Human immunodeficiency virus and acquired immune deficiency syndrome HIV and AIDS

HIV-1 infection is characterized by a clinically asymptomatic phase that eventually leads to immune deficiency, opportunistic infections, neurological symptoms and malignancies which constitute AIDS. The clinical course of HIV-1 infection is highly variable, with untreated individuals developing AIDS from 2-3 years after seroconversion or remaining asymptomatic for over 15 years (Hendriks et al., 1993). The first gene to be associated with resistance to HIV infection was isolated when individuals who had been frequently exposed to HIV-1 but were uninfected, were identified. The gene was the chemokine receptor CCR5 and the resistance was conferred by being homozygous for a 32 bp deletion (CCR5D32) within the coding region (Dean et al., 1996 Liu et al., 1996 Samson et al., 1996). This deletion leads to a premature frame shift and a nonfunctional protein that is not expressed on the cell surface. The discovery of the involvement of CCR5 led to a detailed elucidation of the mechanism of...

Immune Function

The innate immunity is preserved over the life-span. Immune changes, dysregulations, mainly affect acquired immunity and lead to a gradual increase in T-helper (Th) 2 T-helper 1 cells. This change is the result initially of decreased thymic function, and later of accumulative antigen pressure over the life-span. T-Cell subset distribution in peripheral lymphocytes changes with age to a higher memory naive cell ratio, accompanied by changes in cytokine production patterns (Fernandes and Venkatraman, 1993 Fernandes et al., 1997 Thoman and Weigle, 1989 Venkatraman and Fernandes, 1994 Venkatraman et al., 1994). Proliferative capacity of T-cells declines with age (Venkatraman & Fernandes, 1997 Makinodan, 1998 Makinodan et al., 1987). The composition of T-cell subsets in the periphery gradually change with age, resulting in the alteration of T-cell functions in the elderly. There appears to be a macrophage-lymphocyte disequilibrium in aged persons (Lesourd, 1999). There is a shift in the...

Epidemiology and immunogenetics

Important in susceptibility to disease. Several studies have shown an association with HLA-DR3 and the linked genes B8, DQ2 and the C4 null gene. This haplotype is common in the healthy population (20-25 ) and its components are in tight linkage disequilibrium so it has been difficult to identify the component which confers risk of SS. It is now known that the immune response genes are more strongly linked to autoantibody specificity than disease. In West European Caucasian patients with anti-Ro La antibodies the frequency of DR3 is increased to 60-90 in both SS and SLE. In Black patients with anti-Ro La antibodies the frequency of DR3 is increased to 80 . One of the first studies which attempted to identify the part of the haplotype associated with anti-Ro and La found that patients heterozygous for HLA-DQwl and DQw2 had the highest anti-Ro antibody levels. These findings might explain studies of Greek and Israeli patients with primary SS in whom the only significant HLA association...

Other diseases of the intestinal epithelium

The classification of IDI is probably incomplete, since other forms with abnormal small-bowel mucosa have been described. These include mitochondrial DNA rearrangements congenital ente-rocyte heparan sulfate deficiency, phosphoman-nose isomerase deficiency and a carbohydrate-deficient glycoprotein syndrome with hepatic-intestinal presentation.54-59 Rare diseases involving the immune system and small-bowel mucosa,60 or severe intractable enterocolitis of infancy,6 seem clearly different from the above-described diseases. The so-called 'pheno-typic diarrhea' that is an IDI syndrome associated with phenotypic abnormalities and immune deficiency is one of these rare diseases recently reported. The patients present with diarrhea starting within the first 6 months of life (< 1 month in most cases), and have several features in common. They are small for gestational age and have an abnormal phenotype.11 All have facial dysmor-phism with prominent forehead, broad nose and hypertelorism....

The Search For Novel Nonmhc Susceptibility Genes

Recently, it has been described that the position of provisional loci found in T1DM colocalize or overlap with loci found in different autoimmune inflammatory diseases (48,172). This is consistent with the hypothesis that, like the MHC, some of these provisional loci may involve common susceptibility genes or biochemical pathways that are central to normal immune function. Concannon et al. (148) identified a novel locus for T1DM (MLS 3.31) (Table 2) at human chromosome 1q at marker D1S1617. This locus colocalizes with loci for systemic lupus erythematosus (SLE) (49) and ankylosing spondylitis (50). In human SLE, this locus is linked to high serum levels of antichromatin antibody, and in mouse SLE. This locus is linked to both anti-chromatin and anti-DNA antibody production (173,174). This colocalization of suggestive genetic linkage for three autoimmune diseases suggests that genes at this locus may be involved in a pathway that might affect the quantitative regulation of antibody...

Discharge And Home Healthcare Guidelines

Teach the patient the importance of avoiding exposure to individuals who are known to have acute infections. Emphasize the need for preventing trauma, abrasions, and breakdown of the skin. Be sure the patient understands the need to maintain a good nutritional intake to enhance the immune system and resistance to infections. Teach the patient the potential for bleeding and hemorrhage, and offer instruction in measures to prevent bleeding, including the use of a soft toothbrush and an electric razor. Discuss the need for regular dental examinations. Explain the importance of maintaining regular bowel movements to prevent straining COMPLICATIONS. Teach the patient to recognize the indicators of a systemic infection. Stress the fact that fever and usual wound infection signs may or may not be present since the immune system may be depressed. Instruct the patient about the symptoms that require immediate medical intervention, and make sure the patient knows whom to notify....

From immunogenetics to immunomics functional prospecting of genes and transcripts

Human and mouse genome and transcriptome projects have expanded the field of 'immunogenetics' beyond the traditional study of the genetics and evolution of MHC, TCR and Ig loci into the new interdisciplinary area of 'immunomics'. Immunomics is the study of the molecular functions associated with all immune-related coding and non-coding mRNA transcripts. To unravel the function, regulation and diversity of the immunome requires that we identify and correctly categorize all immune-related transcripts. The importance of intercalated genes, antisense transcripts and non-coding RNAs and their potential role in regulation of immune development and function are only just starting to be appreciated. To better understand immune function and regulation, transcriptome projects (e.g. Functional Annotation of the Mouse, FANTOM), that focus on sequencing full-length transcripts from multiple tissue sources, ideally should include specific immune cells (e.g. T cell, B cells, macrophages,...

What is Multiple Sclerosis

MS has been actively studied for more than a century, but much about MS, including its cause, remains a mystery. What is known MS is one of the first chronic CNS neurodegenerative diseases recognized to have an inflammatory component driving pathogenesis and clinical disability (11,12). Although MS-initiating agents events remain a subject of speculation, pedigree and epidemiological studies indicate that MS susceptibility has both environmental and genetic components. On the genetic level, the MHC class II locus has been most consistently correlated with MS susceptibility, although many loci appear to have roles in modulating MS risk and pathogenesis. From these observations, inappropriate activation of myelin-specific CD4+ T cells are suspected to have causative roles in MS pathogenesis. Interestingly, epidemiology studies also suggest that encounters with unknown environmental factors around puberty prime individuals to develop MS 10 to 20 yr later. Furthermore, researchers have...

Effect of Genetic Background on Antigen Presentation

The association of HLA-DR3 with SCLE likely has a strong influence on antigen presentation. The linkage disequilibrium of the -308A TNF promoter polymorphism with DR3 seen in SCLE is likely to be important in determining immune response (Werth et al. 2002). One could imagine that increased TNF-a production from the -308A polymorphism leads to increased apoptosis and Ro antigen presentation. In the context of HLA-DR3, this could stimulate an autoantibody response and trigger the development of autoimmunity.

Therapeutic Agents Inhibit Retrovirus Replication

Replication Cycle Hiv

The success of HAART in treating AIDS has opened discussion of whether it might be possible to eradicate all virus from an infected individual and thus actually cure AIDS. Most AIDS experts are not convinced that this is possible, mainly because of the persistence of latently infected CD4+ T cells and macrophages, which can serve as a reservoir of infectious virus if the provirus should be activated. Even with a viral load beneath the level of detection by PCR assays, the immune system may not recover sufficiently to clear virus should it begin to replicate in response to some activation signal. In addition, virus may persist in sites such as the brain, not readily penetrated by the antiretroviral drugs, even though the virus in circulation is undetectable. The use of immune modulators, such as recombinant IL-2, in conjunction with HAART is be- ing examined as a strategy to help reconstitute the immune system and restore normal immune function.

KIR Defense Against Microorganisms

Inhibition mediated by specific KIR HLA combinations has also been implicated in the outcome of HCV infection (Khakoo et al. 2004) based on a genetic study of these loci among individuals who either cleared the virus or had persistent infection. The presence of alleles encoding the inhibitory KIR2DL3 and its HLA-C group 1 ligands was shown to associate with HCV clearance, and this effect appeared to be codominant two complete pairs of KIR2DL3 and HLA-C group 1 (i.e., homozygosity of KIR2DL3 and HLA-C group 1 KIR2DL3 KIR2DL3 C1 C1) was strongly associated with viral clearance, whereas one complete pair was relatively neutral, and no complete pairs of KIR2DL3 C1 associated with viral persistence. The binding affinity of KIR2DL3 for HLA-C group 1 allotypes is measurably lower than that of KIR2DL2 and KIR2DL1 for their cognate ligands (group 1 and group 2 allotypes, respectively) (Winter et al. 1998), resulting in transmission of weaker inhibitory signals to the effector cell. In HCV...

Metabolic Function and Essentiality

As noted above, CoA is required for Golgi function, involved in protein transport. Pantothenate deficiency can therefore cause reductions in the amounts of some secreted proteins. Other metabolic responses to deficiency include a reduction in urinary 17-ketosteroids, a reduction in serum cholesterol, a reduction in drug acetylation, a general reduction in immune response, and an increase in upper respiratory tract infection.

Factors to Be Considered on an Individual Basis Favoring Treatment of Otitis Media with Effusion

Demonstrate their efficacy in eliminating middle ear effusion.15 Despite the apparent efficacy of systemic corticosteroid therapy in clinical trials, a recent official government guideline found the risks of this option in children to outweigh its possible benefits.16 Clinical trials have not been reported that have tested the efficacy of topical nasal corticosteroid treatment, immunotherapy, and control of allergy in children who have nasal allergy and middle ear disease. Nevertheless, this method of management seems reasonable in children who have frequently recurrent or chronic otitis media with effusion and evidence of upper respiratory allergy.

Antidiuretic hormone ADH See vasopressin

Antigen A substance inducing and reacting in an immune response. Normally antigens have molecular weights greater than about 1 kDa. The antigenic determinant group is termed an epitope, and the association of this with a carrier molecule (that may be part of the same molecule) makes it active as an antigen. Thus dinitrophenol-modified human serum albumin is antigenic to humans, dinitrophe-nol being the hapten. Usually antigens are foreign to the animal in which they produce immune reactions.

Eligibility criteria 167

Effector An organ or part of an immune system that becomes active in response to stimulation. effector cells The active cells of the immune system responsible for destroying or controlling foreign antibodies. Also cell or organ by which an animal responds to internal or external stimuli, often via the nervous system.

Oilbased lubricant See lubricant

Opportunistic infection Infection that arises when the immune system is suppressed or otherwise compromised. The primary effect of HIV on the body is the gradual destruction of key immune-system cells, particularly helper T lymphocytes. Helper T cells, also known as CD4 lymphocytes, play a key role in initiating and coordinating immune responses. The loss of CD4 lymphocytes and other cells with the CD4 receptor, especially mono-cytes macrophages, causes a progressive weakening of the immune system. This in turn gives microbes that are normally kept in check by the immune system an opportunity to flourish and cause disease. For this reason, the diseases induced by these microbes are known as opportunistic infections. opportunistic infections are responsible for up to 90 percent of all AIDS-related deaths. They develop primarily from two sources. Some, such as toxoplasmosis, occur through the reactivation of an infection acquired by many people earlier in life, often during childhood....

HLA Associations with Extraocular Disease

Graves' disease has been associated with HLA-DRBi*030i as well as HLA-DRBi*o8 in early onset disease in Caucasians i4, i2i , but not in Taiwanese patients, in whom HLA-A*0207 was weakly associated 39 . HLA-DQ associations were thought to be by linkage disequilibrium i2i . A mouse transgenic for HLA-DRBi*030i developed inflammatory thyroid disease when immunized with a plasmid encoding human thyrotropin receptor 22 . In a review of studies involving genome wide scans in autoimmune thyroid disease, the author felt the HLA associations with Graves' disease most likely were modulating genes, increasing risk but not primary to disease pathogenesis ii0 . Another gene important in the immune response that was implicated was the gene for CTLA-4 and several other candidate loci were described ii0 .

Neuromuscular Junction And Muscle

All small cell lung cancers with or without paraneoplastic symptoms express the Hu antigen, and 16 percent of patients with small cell lung cancer but lacking neurological dysfunction develop low titers of anti-Hu antibody. There is no overlap between the titers of anti-Hu antibodies in small cell lung cancer with paraneoplastic encephalomyelitis and sensory neuronopathy (average titer, 4592 U ml) and those without neurological symptoms (average titer, 76 U ml). All patients with low titers of anti-Hu antibody had the tumor confined to the thorax at diagnosis. In contrast, more than 50 percent of patients with small cell lung cancer without the anti-Hu antibody had systemic metastases at diagnosis. These findings, and the tendency of small cell lung cancer from patients with paraneoplastic encephalomyelitis and sensory neuronopathy to remain localized and undetectable until autopsy, suggest that the antitumor immune response contributes to the more...

The T Cell Receptor Cofactor CTLA4 in MG

Of the Immune System CTLA-4 is an essential component of the immune system present on T cells, B cells, monocytes, and many other cells. It serves as a negative regulator for T cell activation. Animals deficient for the gene coding for CTLA-4 (Ctla-4) show a massive T cell lymphoproliferative disorder with increased numbers of activated T cells and elevated basal levels of serum immunoglobulins, resulting in autoimmune-like tissue destruction (Waterhouse etal., 1995). Defect in expression function of CTLA-4 should thus result in an abnormal T cell activation and an exaggerated inflammatory immune response. Ctla-4 variants that are associated to decreased expression function have been described in many autoimmune disorders, including MG (Huang et al, 1998a Kristiansen et al., 2000). The gene is located on human chromosome 2q33. Genetic variants of Ctla-4 includes an (AT)n microsatellite within the 3' untranslated region of exon 3 (3'UTR) at position +642, SNPs in the promoter region at...

Other MHCassociated diseases

A number of ''third-party'' diseases are associated with the MHC but are apparently structurally and functionally unrelated to HLA class I and class II loci and associated immune response pathways. They are most likely the result of chance events in evolution that brought genes into juxtaposition with HLA loci, although a functional connection cannot be ruled out. A classic example is the linkage of congenital adrenal hyperplasia, which is due to defective alleles in the CYP21 genes that encode an enzyme involved in biosynthesis of steroids, by cortical cells in the adrenal gland, namely 21-hydroxylase.

Immunogenetic Polymorphisms

The association of the MHC genes with abacavir hypersensitivity and carbamaze-pine hypersensitivity is biologically plausible because drug-specific T-cells have been demonstrated in affected individuals confirming the immune nature of the reactions (120). However, an association with genes on the MHC should not necessarily imply that the adverse reaction is immune-mediated. This is because there is extensive linkage disequilibrium within the MHC, and at least 40 of the genes do not have an immune function (121). This is also exemplified by the iron-handling disorder hemochromatosis, which shows an association with various HLA genes (122), but in fact has been shown to be caused by mutations in the linked HFE gene (123,124). Two examples of ADRs may also fall into this category.

Acute exposure Inhalation

Changes in lymphocyte populations associated with reduced immune function have been demonstrated in floor-laying workers exposed to a number of solvents including methyl n-butyl ketone (Denkhaus et al., 1986), but functional changes in immunocompetence have not been shown (Topping et al., 2001).

Adverse Effects Contraindications and Drug Interactions

Vaccinations should be deferred until several months after the administration of y-globulin because the antibodies contained in this preparation may interfere with the development of the host immune response. Individuals who were vaccinated shortly before receiving immune globulin may require revaccination at a later time.

Therapy of Zoster Pain Postherpetic Neuralgia and Other Neurological Complications

All data on opioid use in chronic nonmalignant pain collected so far are insufficient to address the long-term efficacy of opioids and the development of adverse effects that might only arise during long-term use, e.g. their effect on the immune system. However, many patients with pain due to central and peripheral nerve injury can be successfully and safely treated on a chronic basis with stable doses of strong opioids without signs of tolerance. The use of opioids requires caution in patients with a history of chemical dependence or pulmonary disease. We recommend using long-acting opioid analgesics (e.g. sustained release morphine preparation) when alternative approaches to treatment have failed. An opioid trial should be tested before invasive therapies are instituted. Furthermore, a trial of opioids should not be delayed to a 'last resort' status. Prophylactic treatment of common side effects notably nausea or constipation is necessary and improves patients' compliance.

Stress Its Definition And Classification

Given the complexity of the stressors that have been used to investigate the changes in the immune system, and the differences in the responses of the individual to these stressors depending on the age, sex, genetic composition, etc., it is perhaps not surprising to find a wide variation in their results that are expressed in the literature regarding the causal relationship between stress and the immune system.

Clinical Features

Mazzotti Reaction Ivermectin

Individual variation (Manson-Bahr and Bell, 1987). The most frequent symptom is itching. This may of be of any degree of severity and is sometimes incapacitating. It is usually generalised and often associated with excoriations. Other acute reactive dermal lesions include papular eruptions anywhere on the body, representing intraepithelial abscesses, transient localised intradermal oedema, and lymphadeno-pathy, particularly of the inguinal and femoral glands. These are typically firm and non-tender and show histological evidence of atrophy, chronic inflammation and fibrosis (Gibson and Connor, 1978). Later, skin lesions give the appearance of premature ageing, with lichenoid change, hyperkeratosis and exaggerated wrinkling of the skin atrophy of the epidermis, with loose, redundant, thin and shiny skin (Anderson et al., 1974a) dispigmentation, often initially hyperpigmented macules, but more typically a spotty depigmentation of the shins, which represents islands of repigmentation...

Treating Torticollis Dizziness

Recurrent mucocutaneous disease is best treated in the prodromal stage or within 48 hours after formation of vesicles. Treatment should consist of 200 mg acyclovir given orally five times per day or 500 mg valacyclovir given orally twice per day or 125 mg famciclovir given orally three times per day for five days. In patients with intact immune systems, adding a regimen of steroid drugs lessens the severity of disease and dries the vesicles but does not shorten the course of the disease. Use of steroid agents in patients with HIV can cause fulminant oral candidiasis.

Mycobacterial disease leprosy

Two successful genome screens have been carried out on affected sib pairs with leprosy so that this is arguably the infectious disease that has been most successfully tackled by family-based linkage analysis. The first initially identified a linkage to chromosome 10p13 (Siddiqui et al., 2001) in Indian subjects and then by typing additional markers a second locus on chromosome 20p12 was identified (Tosh et al., 2002). Intriguingly, this was in a similar position to peaks of linkage identified in genome screens for atopic dermatitis and psoriasis, two disorders also characterized by immune system mediated damage of the skin (Trembath et al., 1997 Cookson et al., 2001). The second genome screen

General aspects of allergy and intolerance 1421 Definitions

Allergy is defined as an abnormal reaction of the immune system to foreign (not infectious) material, leading to injury to the body that may be either reversible or irreversible. In Types of hypersensitivity There are four types of immunological hypersensitivity reactions. Of the four types of hypersensitivity reactions, type I reactions are probably the most important, as will become evident in this chapter. This does not mean though, that other types of reactions or combinations do not occur. A food-allergic reaction takes place only if the immune system of the body reacts to food in a specific way. This is the case if the food has antigenic potency and has the opportunity to stimulate the immune system. Most food allergic reactions occur in infants. This can partly be explained by the fact that the permeability of the intestine in neonates is high, so that proteins can pass across the intestinal mucosa and interact with the immune system. Further, because of the immaturity...

Clinical Appearence Classification

Dermatitis Herpetiformis Palms

It is now well-accepted that all DH patients have celiac disease (CD), although most patients have no overt gastrointestinal symptoms. Marks et al. (1966) first reported abnormalities of the jejunal mucosa in patients with DH. Subsequently, it was recognized that the gastrointestinal abnormalities in DH are the same as in CD (Fry et al. 1967). Confusion concerning the incidence of the enteropathy in patients with DH is derived mainly from two aspects firstly, from the inadequate criteria for the diagnosis of CD, and secondly from confusing DH and linear IgA disease. Before being able to differentiate between the two diseases, one may have thought that some patients with linear IgA-disease were suffering from DH with the absence of bowel disease. Essentially all DH patients have histologic changes of CD that vary from mononuclear infiltrates in the lamina propria and minimal villous atrophy to complete flattening of the small intestinal mucosa (Fig. 2). The typical histological changes...

Neurologic signs and symptoms

Past medical history should be thoroughly explored. A history of malignancy, previous neck problems, associated musculoskeletal disorders, metabolic bone diseases, and smoking habits should be pursued. Patients with a history of rheumatoid arthritis often exhibit signs and symptoms of C1-2 instability. Patients with a history of psoriatic arthritis, ankylosing spondylitis, severe rheumatoid arthritis, or juvenile rheumatoid arthritis also often have associated cervical pathology. A history of intravenous drug abuse or a compromised immune system increases the chance of an infectious process. Because myocardial ischemia and aortic disease can present as neck pain, a complete medical history is needed.

Hyperimmunoglobulinemia 239

Hyperimmunoglobulinemia Abnormally high levels of antibodies in the system. A condition often seen at the outset of HIV infection as the body tries to fight the virus. It was initially not known why this occurred, because patients did not become ill immediately, often for years. As tests to determine the virus in the body became available and easier to use, it became clear that the immune system was engaged in a constant battle with the virus from day one of infection and that the hyper-immunoglobulinemia was part of the body's fight.

Dr Harold Buttram

A combination of subtle brain damage from environmental chemicals, nutritional deficiencies, a crippling of the detoxification systems of the body, food allergies, and an overgrowth of candida in the system produces a very sick child. The manifestation of this will be a crippled immune system. This means the child will have more allergies. He will be sick a lot of the time and on antibiotics. The brain function cannot possibly be normal it would be a miracle if it were. The hyperactivity, attention deficit, and behavioral problems, in my opinion, are all actually a continued spectrum of the same thing.

FCommon side effects

Novel biologic agents and immunotherapy in rheumatoid arthritis. Impressive research focused on the pathogenesis of RA has discovered many new mechanisms that illustrate the complex and multicellular nature of the disease. Potential sites for therapeutic intervention include cells such as T and B lymphocytes, macrophages, fibroblasts, endothelial cells, and dendritic cells, and their many products such as cytokines and adhesion molecules. The development of these agents have already revolutionized the treatment possibilities for patients with RA. How such agents will be merged with presently accepted and effective DMARDs such as MTX will be defined by their effectiveness as disease-controlling and disease-modifying agents, their side effect profile, and their cost.

IL10 Polymorphisms

Single nucleotide polymorphisms (SNPs) or microsatellites, located within the promoter, affect gene transcription and cause inter-individual variations in cytokine production. Such differential cytokine production may confer a certain degree of flexibility in the immune response, with protective or aggressive effects leading to resistance or susceptibility with regard to autoimmune diseases.28


As noted in the section on antioxidant vitamins, antioxidant compounds may have several beneficial effects on MS. However, most antioxi-dant compounds, including selenium, activate the immune system, and this immune-system stimulation may conceivably worsen MS. In fact, in one study of animals with EAE, an experimental form of MS, selenium supplementation worsened the disease course and increased the mortality rate. Also, the severity of the disease was the same for animals fed low-selenium and normal-selenium diets. The results of this study suggest that selenium supplementation may actually be harmful for people with MS. Because of the limited information about selenium, it is not clear whether selenium supplementation in MS produces beneficial effects, harmful effects, or no effects at all. It may be most reasonable for people with MS to avoid selenium supplements until more information is available. Selenium may be obtained in the diet from seafood, meat, and whole grains. If...


Precautions Continued or excessive use can lead to dependence or addiction, and possibly severe psychotic episodes. It should be used with caution by those with glaucoma or other visual problems, high blood pressure, epilepsy or seizures, or those who are generally tense, agitated, or allergic to the drug. It is a stimulant that can mask symptoms of fatigue, and so should be used with caution by those driving or using hazardous equipment. Since it is a stimulant that causes the release of norepi-nephrine, feelings of depression and a severely compromised immune system could occur between the time the neu-rotransmitter is metabolized and the body is able to make more.


Astragalus An herb (Astragalus memranaceious) used in China, reportedly for the purpose of boosting the immune system and preventing chemotherapy-related bone marrow suppression and nausea. In the former Soviet Union and in Japan it is used to treat heart attacks and strokes. The active substances are taken from the root of the plant. Studies have reported that an extract of astragalus, Fraction 3 (F3), has stimulated immune responses in the test tube and in animal studies. Clinical trials of astragalus in people will determine whether such effects can be duplicated in the body. Astragalus is believed to be nontoxic, but there are reports that it can trigger low blood pressure and increase the amount of urine produced, resulting in dizziness and fatigue. Overdosing of astragalus may cause immunosuppression, and plants from different sources may vary in quality and produce different results.

Lovastatin 289

Long-term survivor An individual infected with HIV for at least seven to 12 years (different researchers and authors use different time spans) who yet retains a CD4 cell count within normal range. It has been found that the good health of long-term survivors probably is due to multiple factors, which may vary from individual to individual. Multiple immune system factors, genetic and other host factors, and viral factors contribute to the clinical profiles of these patients, who usually have preserved immune function and low levels of HIV in their bodies.

Features of the MHC

For instance, MHC class I and class II molecules are polygenic and highly polymorphic so that different individuals are likely to select different peptides for presentation. Another striking property of MHC genes, that may also help them to keep pace with rapidly evolving pathogens, is their evolution by sequence exchange, by either intra-allelic or intra-locus gene conversion. The clustering of polymorphic genes in the MHC and strong linkage disequilibrium across the complex may also assist in coordinating the battery of different immune response mechanisms.


There is no clinical evidence of the efficacy of opioids for the treatment of FMS (31). Short-acting opioids may be useful when taken 30 to 60 minutes prior to exercise or physical therapy for patients in whom pain prevents the treatment. Chronic, moderate-to-high dose opioid usage may induce problems with deep sleep and with the immune system (32). However, chronic opioid analgesic therapy (COAT) for select patients who need significant help to become functional and maintain their functionality, may be indicated. Extended time-release opioids such as Oxycontin, Durgesic patches, or extended release morphine may be used. An opiate agreement must be used, and the patients told of the possibility of dependence. They should be monitored regularly to evaluate the patients' function and their appropriate use of the medication (33).

Fat Soluble Vitamins

High intakes of vitamin E and vitamin K appear to be relatively nontoxic. Some studies show that intakes of vitamin E greater than ca. 500 mg d (50 times the recommended daily intake) can impair functioning of white cells and the immune system. It also is known that excess amounts of vitamin E can antagonize vitamin K's role in the clotting mechanism. Although vitamin K is fat soluble, it is readily excreted from the body, making toxicity unlikely. However, one form of vitamin K

How Much is Known

Endocrine disruption, linked to asthma, developmental and reproductive effects. Medical waste with PVC and pthalates is regularly incinerated causing public health effects from the release of dioxins and mercury, including cancer, birth defects, hormonal changes, declining sperm counts, infertility, endometriosis, and immune system impairment.


An allergy is a reaction of the immune system to a substance that is typically harmless to most people. In a person with an allergy, the body treats the substance, called an allergen, as an invader. Some of the most common allergens are pollen, dust mites (tiny bugs that live in household dust particles), molds, cockroaches, animal dander (especially cats and dogs), and foods such as peanuts, egg whites, wheat, fish (including shellfish), soy, citrus, and dairy products (milk products). Insect bites or stings can also cause allergic reactions. Allergy symptoms can be seasonal, occurring only when the allergen (such as pollen) is in the air, or chronic, such as an allergy to dust mites. With most common allergies, the person's immune system produces antibodies against the particular allergen involved. When the person is exposed to the allergen, the attack mounted by the immune system against this substance triggers the release of certain body chemicals that cause the symptoms...


Oxamniquine is a tetrahydroquinoline, active against S. mansoni in a single dose of 15mg kg body weight (Bassily et al., 1978). Its mechanism of action is not completely understood. It is probably metabolized by the parasite into an ester and subsequently alkylates macro-molecules. Oxamniquine also disrupts the tegument of the male schistosome and could work in synergism with the immune system in a way analogous to praziquantel (Lambertucci et al., 1989). Female worms may survive, but cannot lay eggs. Vaccination against schistosomiasis has been under active investigation for over three decades. Most vaccines have been targeted toward prevention of infection. More recently, investigators have worked toward developing a vaccine that would minimize end-organ damage by inducing a modification in the immune response to eggs. This would be an antidisease vaccine (Bergquist and Colley, 1998). Finally, Dr Capron in France is currently pursuing a vaccine whose primary effort is directed at...

Secondary Syphilis

Syphilis Mucous Patches

Approximately eight weeks after the initial presentation of a chancre, a generalized infection ensues. This is a result of proliferation and systemic dissemination of T. pallidum and persists until a sufficient immune response develops. Constitutional symptoms including fever, headache, arthralgias, malaise, pharyngitis, and generalized lymphadeno-pathy are common. The dominant feature of secondary syphilis is a mucocutaneous rash, which appears in 90 of patients. While there is significant variation, the characteristic rash begins as small pink to red macules symmetrically distributed on the trunk and extremities, also involving mucous membranes. This will progress to a papular rash and spread to the distal extremities to involve the palms and soles. Eventually the rash will develop a coppery color and become papulosquamous. It will often have the appearance of pityriasis rosea and follow skin cleavage lines, although distinguishable by its involvement with the palms and soles. The...


A distinct extended haplotype called the high human immune responder 8.1 ancestral haplotype (A*01, B*08, DRB1*0301, DQB1*0201, TNFAB*a2b3, C2*C) has also been linked with anti-Ro SSA production (Price et al. 1999, Lio et al. 2001). Located on human chromosome 6, the 8.1 ancestral haplotype is in linkage disequilibrium with the gene for tumor necrosis factor-alpha (TNF-a), an important proinflammatory mediator of the cutaneous innate immune response. A single nucleotide polymorphism in the promoter region of TNF-a G-308A, has been found to be associated with the SCLE phenotype (Werth et al. 2000, Millard et al. 2001a). Following exposure to UVB radiation in the presence of IL-1a, this promoter polymorphism produced


Effects An adaptogen that boosts the immune system, balances the bodily systems, counteracts stress, and improves mental functioning. It may reduce symptoms of altitude sickness by thinning the blood. It has been used to treat viral hepatitis, may protect the liver from various toxins, and may be useful in treating chronic bronchitis, peptic ulcer disease, hypertension, insomnia, and high cholesterol.


The discussion so far has been devoted to nonselective CB1 and CB2 agonists, such as THC, because most of the analgesic literature has been generated with these compounds. The discovery of the CB2 receptor in nonneuronal tissues such as immune cells attracted interest in its potential modulation of immune function. However, there are now numerous reports that CB2 selective agonists have analgesic properties. One such CB2 selective agonist is AM 1241, which was shown to be highly active in a thermal pain model in rats (93). It was also shown to suppress capsaicin-induced hyperalgesia (94). HU 308 is another CB2 selective agonist that has been reported to produce analgesic effects in rodents (95). The advantage of these compounds is that they are devoid of the behavioral effects produced by CB1 selective agonists. At present there are no reports of clinical efficacy of CB2 selective agonists.


Recent evidence also strongly suggests that opioids may alter immune function and opioid-related receptors have been found to reside on immune cells (Makman 1994). However, pain itself can impair immune function and it is not clear that long-term opioid use leads to clinically significant immunosuppression.


The diagnosis of neurocysticercosis should be considered in any patient who is a resident or immigrant from areas endemic for cysticercosis, or who has traveled to areas endemic for cysticercosis, and has new onset partial seizures, with or without secondary generalization, cognitive impairment, confusion, stupor, or signs of raised ICP. In the majority of patients, the clinical manifestation of parenchymal granulomas is partial seizures. Patients with meningeal cysticercosis may present with headache, vertigo, vomiting, papilledema, an altered level of consciousness, and gait disturbances due to the intense and widespread immune response in the subarachnoid space and the subsequent development of hydrocephalus. Cysticerci located in the spinal canal may manifest with signs and symptoms similar to an intraspinal tumor. 124

Parasitic Pathogens

C. parvum also causes a watery diarrhea that can be persistent or chronic, especially in patients with compromised immunity. There is no effective antimicrobial therapy for cryptosporidiosis. Paromomycin (500 mg by mouth three times daily for 7 days) has been variably reported to have clinical efficacy and has, as reported by Smith and colleagues (1998), been used with some success in combination with azithromycin (Zithromax) for the treatment of cryptosporidiosis in patients with AIDS. For patients with cryptosporidiosis and AIDS, improvement of immune function with highly active antiretroviral therapy may be successful in clearing cryptosporidial infection. There is a separate chapter on treatment of gastrointestinal in HIV-infected patients (see Chapter 46, Gastrointestinal and Nutritional Complications of HIV Infection).

Group A Strep

Are spread by direct contact with nose and throat discharge, or by touching infected skin lesions. The risk is greatest when the child is ill or has an infected wound. Health conditions that impair the immune system make infection with GAS more likely. In addition, there are some strains of GAS that are more likely to cause serious disease.


The mechanism of action is still unclear. It is known that it downregulates TNF-a in conditions with increased TNF-a production 38 . TNF-a is secreted by macrophages and T-helper lymphocytes upon activation and is thus found in many inflammatory diseases such as uveitis. However, it is not a simple inhibitor of TNF-a it can switch off the overproduction of TNF, but does not inhibit the basal level needed for normal cellular function. It also inhibits angiogen-esis, which is essential for many physiologic and pathologic pathways. Other effects of thalidomide on the immune system include inhibition of leukocyte chemotaxis, decrease in density of adhesion molecules, inhibition of lymphocyte proliferative responses, change in the levels of different cytokines and reduction of phagocytosis, thus preventing the invasion of the eye by inflammatory cells 56 .


The penetration of cercariae through the skin may result in an itchy, papular rash, known as swimmer's itch. This is a sensitisation phenomenon because it rarely occurs on primary exposure. This reaction is most severe when the skin is penetrated by avian schistosomes, which die in the dermis. Migration and development of the cercariae into adult worms then occurs. Between four and eight weeks after acute infection, oviposition results in an acute immune response, which may result in fever, eosinophilia, skin rashes, hepatosplenomegaly and abdominal pain. This syndrome is most severe with the S. japonicum form of the disease but also occurs in immu-nologically naive travellers it is known as Katayama fever (Doherty, 1996). Although symptoms and signs usually subside within a few weeks, Katayama fever may be fatal. The next symptoms that develop are associated with the emergence of eggs into the faeces (S. japonicum, S. mekongi, S. intercalatum and S. mansoni) or urine (S. hae-

Sunlight Even before studies were published about the effect of sunlight on HIV, AIDS-knowledgeable physicians were cautious about the dangers of sunlight to persons with AIDS or asymptomatic hiv infection. It had long been known that ultraviolet light can damage or suppress the Langerhans cells of the skin. These cells are an important part of the immune system, and are cells which HIV is known to infect. Strong sunlight, probably the ultraviolet rays, can impair immune response. Laying out in the sun or playing volleyball in one's swimsuit for hours at a time are examples of activities about which to be worried. t-helper cell counts drop almost invariably after someone spends a long weekend at the beach. while regular exposure during daily activities is not of concern, it is noted that a number of drugs used by persons with HIV AIDS make the skin much more sensitive to the sun than usual. Additionally, in the late 1980s, researchers at the centers for disease control and prevention...


Insulin deficiency causes diabetes mellitus (die-uh-BEET-eez muh-LIET-uhs), a condition in which cells are unable to obtain glucose, resulting in abnormally high blood glucose concentrations. In type I diabetes the immune system attacks the insulin-producing islet cells. The cells die. Type I generally is treated with daily injections of insulin into the blood and sometimes with islet cell transplant. Type II diabetes usually occurs after age 40, and it is more common than type I. Type II is caused by insufficient insulin or less responsive target cell receptors. Although type II is hereditary, its onset correlates with obesity and an inactive lifestyle. Type II diabetes can often be controlled through exercise and diet. In diabetes, excess glucose inhibits water reabsorption by the kidneys, producing large amounts of urine. Dehydration and kidney damage can result. Lack of insulin can lead to acid-base and electrolyte imbalances. These changes may result in nausea, rapid breathing,...


Large amounts (several hundred milligrams or more) intensify users' high, but may also lead to bizarre, erratic, and violent behavior. These users may experience tremors, vertigo, muscle twitches, paranoia, or, with repeated doses, a toxic reaction closely resembling am-fetamine poisoning. Physical symptoms may include chest pain, nausea, blurred vision, fever, muscle spasms, convulsions, and coma. Death from a cocaine overdose can occur from convulsions, heart failure, or the depression of vital brain centres controlling respiration. With repeated administration over time, users experience the drug's long-term effects. Euphoria is gradually displaced by restlessness, extreme excitability, insomnia, and paranoia - and eventually hallucinations and delusions. These conditions, clinically identical to amfetamine psychosis and very similar to paranoid schizophrenia, disappear rapidly in most cases after cocaine use is ended. While many of the physical effects of heavy continuous use are...
