    Acquired immunodeficiency syndrome, or AIDS, is a new illness that occurs in previously healthy individuals. It is characterized by immunodeficiency, opportunistic infections and unusual malignant diseases. Life-threatening single or multiple infections with viruses, mycobacteria, fungi or protozoa are common. A rare neoplasm, Kaposi's sarcoma, has developed in approximately one third of patients with AIDS. More than 800 cases of AIDS have been reported in North America, over 24 of them in Canada. The majority of patients are male homosexuals, although AIDS has also developed in abusers of intravenously administered drugs, Haitian immigrants, individuals with hemophilia, recipients of blood transfusions, prostitutes, and infants, spouses and partners of patients with AIDS. The cause of AIDS is unknown, but the features are consistent with an infectious process. Early diagnosis can be difficult owing to the nonspecific symptoms and signs of the infections and malignant diseases. Therefore, vigilance by physicians is of utmost importance. PMID:6342737

    A recently recognized syndrome of acquired immunodeficiency (Acquired Immunodeficiency Syndrome-AIDS) has arisen since June 1981. It has received international attention. The clinical spectrum consists of repeated opportunistic infections, rare malignancies, and autoimmune phenomena, occurring in previously healthy adults with no history of an immunologic disorder. The population subset at risk for this syndrome appears to be predominantly homosexual American males and intravenous drug abusers with rare cases being reported in heterosexuals, hemophiliacs, and foreign patients, especially Haitians. The immunologic aberrancy in all patients described appears limited to T-lymphocyte hyporesponsiveness and imbalance of T-helper and suppressor cells. This disordered immunoregulation is a consistent finding in all reported cases and appears to predispose to the opportunistic infections and malignancies which have been associated with a 40 percent mortality. The underlying factor responsible for the immunoregulatory defect is unknown but possible etiologies include a transmissible infectious agent, drug use, chronic antigen stimulation, and spermatozoa exposure. Treatment of the associated infections and malignancies has been a frustrating endeavor as many patients respond incompletely or relapse soon after successful treatment course. Preventive measures, including patient education, physician awareness, and immunomodulating agents, are discussed. PMID:6134399

    On June 4, 1981, MMWR published a report about Pneumocystis carinii pneumonia in homosexual men in Los Angeles. This was the first published report. A years later, this disease was named acquired immunodeficiency syndrome (AIDS). In the following year, Montangier et al in France discovered the causative agent, which they called lymphadenopathy virus (LAV), now known as human immunodeficiency virus (HIV). In 1985, solid-phase enzymeimmunoassay for the detection of the antibody to HIV was developed. Since then, other new techniques for the identification of HIV infection have been become available. These include more sensitive methods (for example; polymerase chain reaction techniques). Although these techniques facilitate early and definite diagnosis of infection, these tests may fail to detect the antibody in sera during window period of infection or overdiagnose infection in sera contaminated with genes not related to HIV. Although preventing blood exposure is the primary means of preventing occupationally acquired human immunodeficiency virus (HIV) infection, appropriate post-exposure management is an important element of workplace safety. Information suggesting that zidovudine (ZDV) postexposure prophylaxis (PEP) may reduce the risk for HIV transmission after occupational exposure to HIV infected blood prompted a Public Health Service (PHS) interagency working group, with expert consultation, and recommendations on PEP and management of occupational exposure to HIV in relation to these findings were discussed.

  7. Mycobacterial disease, immunosuppression, and acquired immunodeficiency syndrome.

    PubMed Central

    Collins, F M

    1989-01-01

    The mycobacteria are an important group of acid-fast pathogens ranging from obligate intracellular parasites such as Mycobacterium leprae to environmental species such as M. gordonae and M. fortuitum. The latter may behave as opportunistic human pathogens if the host defenses have been depleted in some manner. The number and severity of such infections have increased markedly with the emergence of the acquired immunodeficiency syndrome (AIDS) epidemic. These nontuberculous mycobacteria tend to be less virulent for humans than M. tuberculosis, usually giving rise to self-limiting infections involving the cervical and mesenteric lymph nodes of young children. However, the more virulent serovars of M. avium complex can colonize the bronchial and intestinal mucosal surfaces of healthy individuals, becoming virtual members of the commensal gut microflora and thus giving rise to low levels of skin hypersensitivity to tuberculins prepared from M. avium and M. intracellulare. Systemic disease develops when the normal T-cell-mediated defenses become depleted as a result of old age, cancer chemotherapy, or infection with human immunodeficiency virus. As many as 50% of human immunodeficiency virus antibody-positive individuals develop mycobacterial infections at some time during their disease. Most isolates of M. avium complex from AIDS patients fall into serotypes 4 and 8. The presence of these drug-resistant mycobacteria in the lungs of the AIDS patient makes their effective clinical treatment virtually impossible. More effective chemotherapeutic, prophylactic, and immunotherapeutic reagents are urgently needed to treat this rapidly increasing patient population. PMID:2680057

    All gallium-67 citrate scans obtained in patients with acquired immunodeficiency syndrome (AIDS) at the Clinical Center, National Institutes of Health (Bethesda, Md.) were retrospectively analyzed and correlated with the results of bronchoscopy, chest radiography, and endoscopy. There were 164 scans of 95 patients. Twenty scans were from patients with Pneumocystis carinii pneumonia; 19 were abnormal, for a sensitivity of 95%. Ga-67 uptake tended to be less in patients receiving therapy for P. carinii pneumonia. Chest radiographs were normal at least initially in three patients with abnormal scans and P. carinii pneumonia. Unusually prominent colonic activity was associated with infection in some patients. No lesions of Kaposi sarcoma showed tracer uptake. Gallium scanning is useful for detecting P. carinii pneumonia and other opportunistic infections in patients with AIDS, but it is not useful for localizing Kaposi sarcoma.

    AIDS (acquired immunodeficiency syndrome) seems to be related to human immunodeficiency virus (HIV) and is characterized by severe T-helpers lymphocyte dysfunction. Many of the AIDS patients (47-70%) develop pulmonary manifestations, both infectious and neoplastic, in the course of their disease. In the Department of Infectious Diseases of our Hospital are studied many patients HIV+. Every year 246 seropositive new patients have been discovered. Among them we have studied 25 subjects with respiratory disease, by chest radiographs; successively, according to clinical picture, we have performed thoracic computed tomography, Gallium scintigraphy, fiberoptic bronchoscopy with transbronchial biopsy (TBB), bronchoalveolar lavage (BAL); the majority of these patients (68%) had AIDS, only 28% had ARC and 4% had PGL. In our experience, the diagnosed diseases were mainly infections (92%), and most frequently (52%) due to Pneumocystis carinii, alone or in association with other etiologic agents. We have not found pathognomonic radiographic abnormalities, but chest X-ray evaluated with clinical and laboratory data, may often be useful to obtain diagnostic indications and in order to determine a more specific and aggressive diagnostic approach.

    Patients infected by the human immunodeficiency virus are predisposed to many infectious and noninfectious complications and often receive a variety of drugs. Furthermore, they seem to have a particular susceptibility to idiosyncratic adverse drug reactions. It is therefore surprising that only a few cases of the neuroleptic malignant syndrome have been described in patients with the acquired immunodeficiency syndrome. A high index of suspicion is required to diagnose the neuroleptic malignant syndrome in these patients, as its usual manifestations, including fever and altered consciousness, are frequently attributed to an underlying infection.

    1987-01-01

    In addition to abnormalities in systemic immune function, patients with the acquired immunodeficiency syndrome (AIDS) and the pre-AIDS syndromes have significant abnormalities in the distribution of T-cell subsets in the intestinal tract. Such immune deficits predispose such patients to opportunistic infections and tumors, many of which involve the gastrointestinal tract. For example, Candida albicans often causes stomatitis and esophagitis. Intestinal infections with parasites (Cryptosporidium, Isospora belli, Microsporidia) or bacteria (Mycobacterium avium-intracellulare) are associated with severe diarrhea and malabsorption, whereas viruses like cytomegalovirus and herpes simplex virus cause mucosal ulcerations. Clinically debilitating chronic diarrhea develops in many AIDS patients for which no clear cause can be identified. Enteric pathogens like Salmonella and Campylobacter can be associated with bacteremias. Kaposi's sarcoma and lymphoma involving the intestinal tract are now well-recognized complications of AIDS. Although AIDS is not associated with a pathognomonic liver lesion, opportunistic infections and Kaposi's sarcoma or lymphoma may involve the liver. ImagesFigure 3.Figure 4.Figure 5.Figure 6.Figure 7.

    2002-04-01

    The purpose of this study was to determine if older African Americans are disproportionately affected by acquired immunodeficiency syndrome (AIDS), and to review the clinical impact of AIDS and the importance of prevention and treatment efforts. A review of the literature and statistics was obtained using Medline and the AIDS Public Information Data Set offered by the Centers for Disease Control and Prevention. Twenty-seven percent of the U.S. population is above the age of 50, and the number of AIDS cases in this group is growing, with African Americans accounting for the highest proportion of cases and deaths. Testing for HIV may be delayed and symptoms attributed to other illnesses. Though 5% of new cases occur in those over 50, prevention programs, testing, and the perception of risk by providers may be insufficient. There are few research studies on HIV treatment in older patients and no specific guidelines for antiretroviral treatments available. Although death rates for AIDS has been declining, adults over 50 still have the highest mortality rate. Co-morbid conditions, such as heart disease and hypertension, may require taking multiple drugs, which may complicate treatment. Increasing heterosexual transmission rates and a lack of information on HIV reinforces the need for specific prevention programs targeted toward older African Americans.

    Antisense oligodeoxynucleotides containing internucleoside methylphosphonate linkages were examined for their ability to inhibit human immunodeficiency virus (HIV)-induced syncytium formation and virus expression. HIV inhibitory activity was found to be dependent on both chain length and the number of phosphonate residues. Introduction of 18 phosphonate groups in an oligomer of chain length 20 significantly increased HIV inhibitory activity relative to the parent oligonucleotide, whereas 5 such groups showed little or no increase in the HIV inhibition capacity. Methylphosphonate-linked oligomers are more stable to nuclease degradation and hence could be potentially useful in the treatment of acquired immunodeficiency syndrome. PMID:3174646

    A 53-year-old white man had fever, malaise, and dyspnea on exertion. His chest roentgenogram was normal, but pulmonary function tests showed impaired diffusion capacity and a gallium scan showed marked uptake in the lungs. Results of an open-lung biopsy documented Pneumocystis carinii pneumonia. Immunologic test results were consistent with the acquired immunodeficiency syndrome. The patient denied having homosexual contact or using intravenous drugs. Twenty-nine months before the diagnosis of pneumocystis pneumonia was made, the patient had had 16 transfusions of whole blood, platelets, and fresh-frozen plasma during coronary artery bypass surgery at another medical center. This patient is not a member of any currently recognized high-risk group and is believed to have contracted the acquired immunodeficiency syndrome from blood and blood-product transfusions.

    As health care professionals, we face a grave risk of acquiring HIV infection in the course of our work. But how many of us really know the precautions to be applied in the hospital set up in dealing with HIV infected patients? A knowledge, attitude and practice (KAP) study was conducted in Pune hospitals to assess the current status. Among the results 65% servants had not heard of AIDS, 85% nursing staff did not apply the Universal Safety Precautions (USP) approach, 13.5% resident thought that the HIV was not transmitted by blood, 30% consultants would avoid contact with an HIV positive patient. This study has shown that definite lacunae exist in knowledge specific to the particular population in question. A proposal for an education programme which is target specific and one of constant renewal is sought.

    Acquired immunodeficiency syndrome (AIDS) remains ill-defined by lists of symptoms, infections, tumors, and disorders in metabolism and immunity. Low CD4 cell count, severe loss of body weight, pneumocystis pneumonia, and Kaposi's sarcoma are the major disease indicators. Lines of evidence indicate that patients living with AIDS have both immunodeficiency and autoimmunity. Immunodeficiency is attributed to deficits in the skin- and mucosa-defined innate immunity, CD4 T cells and regulatory T cells, presumably relating human immunodeficiency virus (HIV) infection. The autoimmunity in AIDS is evident by: (1) overproduction of autoantibodies, (2) impaired response of CD4 cells and CD8 cells, (3) failure of clinical trials of HIV vaccines, and (4) therapeutic benefits of immunosuppression following solid organ transplantation and bone marrow transplantation in patients at risk of AIDS. Autoantibodies are generated in response to antigens such as debris and molecules de novo released from dead cells, infectious agents, and catabolic events. Disturbances in metabolic homeostasis occur at the interface of immunodeficiency and autoimmunity in the development of AIDS. Optimal treatments favor therapeutics targeting on the regulation of metabolism to restore immune homeostasis.

    We report a case of a 39-year-old West African man with unknown human immunodeficiency virus status diagnosed with gastric toxoplasmosis as the presenting manifestation of acquired immunodeficiency syndrome. Toxoplasma gondii is common in severely immunosuppressed patients and most frequently involves the central nervous system, followed by the eye, myocardium and skeletal muscle, lungs, bone marrow, and peripheral blood. For unclear reasons, gastrointestinal involvement is exceedingly rare and occurs in the context of severe immunosuppression and disseminated disease. To our knowledge, this is the first report in the English literature of a patient with isolated, manifest gastric toxoplasmosis without evidence of concomitant cerebral or extracerebral involvement. It is important for both the clinician and the pathologist to maintain a high index of suspicion for toxoplasmosis in immunosuppressed patients presenting with nonspecific symptoms of gastritis and radiologic and endoscopic presence of thickened gastric folds with or without ulceration.

    We report a case of a patient with acquired immunodeficiency syndrome (AIDS) and ileocecal ulcer. A 31-year-old man was admitted with chief complaints of decreased body weight and abdominal pain. Colonoscopy revealed a round punched-out ulcer on the ileocecal valve. Initially, we suspected entero-Behçet's disease and simple ulcer as the cause of the ileocecal ulcer. However, after histologic examination of tissue biopsies obtained during colonoscopy, we diagnosed the patient as having cytomegalovirus (CMV) enteritis. Based on the patient's white blood cell depletion and CMV enteritis, we performed a human immunodeficiency virus (HIV) antibody test. The test was positive, and the diagnosis of AIDS was established. The number of patients with AIDS has been increasing in Japan; thus, we should consider the possibility of CMV enteritis and AIDS in young adult patients affected by ileocecal ulcer with no notable history.

Only few patients die as a direct result of cardiac dysfunction. Clinico-pathological findings of three cases of toxoplasma myocarditis are reported, one of which presented and died due to massive pericardial effusion. All cases showed diffuse myocarditis with parasites on histopathological examination. Incidence of toxoplasma myocarditis in patients dying with AIDS was 8.3% (3 out of 36 cases).

    Human immunodeficiency virus (HIV) infection is a pandemic disease characterised by impairment of the immune system; the main parameter is a progressive decline in the number of CD4 lymphocytes. This circumstance paves the way for opportunistic infections and the development of neoplastic processes that can lead the patient to a state known as acquired immunodeficiency syndrome (AIDS) and ultimately, results in death. The incorporation of treatment based on a cocktail of different active drugs (highly active antiretroviral therapy) has made it possible to drastically change the panorama of the disease in developed nations; improving quality of life for the patient and delaying the progression of the disease. The oral manifestations of HIV infection have been and continue to be an important component of the disease from the very first descriptions and are indicative of progression. At some point in the course of the disease, nine out of every ten patients will present oral manifestations and, on occasion, these symptoms will be the first sign of the syndrome. It is essential that oral healthcare professionals recognize the hallmarks of the illness. In developed countries, the emergence of new therapies has made it possible to significantly reduce immune deficiency-related oral manifestations, both in terms of frequency, as well as severity. This review analyses the most important oral lesions associated with HIV infection and the current state of affairs in this regard.

    The acquired immunodeficiency syndrome is now the leading cause of death in the world. Liver involvement in opportunistic infections and neoplasms affecting patients with human immunodeficiency disease syndrome are common. Many of these patients also take many medicines and toxins that are potentially harmful to the liver. This is an overview on the aetiology and possible diagnostic guide to determine liver involvement in patients with HIV infection. A literature review was performed on major published series on the liver and HIV infection between 1985 and 1999, both years inclusive. Data and opinions from 5 general reviews and 31 original articles from MEDLINE on liver disease in patients with HIV infection regarding aetiology, pathology, presentation and patient evaluation are summarised. The liver is frequently affected in patients with AIDS. The majority of the patients have hepatomegaly and abnormal liver enzymes secondary to involvement with opportunities infections, AIDS associated neoplasms and drug therapy. Most of the infections reach the liver by lymphohaematogeneous spread from other sites in the body. Methodical approach in patient evaluation is therefore essential for prompt diagnosis and treatment to minimise morbidity and early mortality.

    Diarrhea is a common problem in patients with acquired immunodeficiency syndrome (AIDS), and infections of the colon constitute a significant etiology. Cytomegalovirus (CMV) is the most common opportunistic infection of the colon in patients with AIDS, and it can involve any portion of the colon and the gastrointestinal tract. Because CMV is potentially treatable with either ganciclovir or foscarnet, it is important to evaluate endoscopically the entire colon of patients with AIDS with protracted diarrhea and no cause identifiable with routine stool and laboratory tests. In addition to CMV, there are a variety of other viral, bacterial, protozoal, and fungal infections seen in patients with AIDS. A thorough evaluation will help identify these pathogens, and those that are treatable can be given appropriate therapy.

    Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) is a multisystem disease that can involve the human eyes. Using ophthalmic examination records from January 2006 to November 2015, we retrospectively reviewed all patients who were diagnosed with HIV/AIDS in our hospital. The study was performed at a tertiary referral center in southern Taiwan. Data included age, gender, ophthalmic examinations, systemic conditions, CD4 cell counts, course, and treatment. Eleven patients were identified as having AIDS with uveitis as their presenting manifestation. All were men, with a mean age of 39.5 ± 11.4 years (range 24-56). The mean CD4(+) T-cell counts were 91.7 ± 50.3 cells/μl (range 27-169). Ocular diagnoses included cytomegalovirus (CMV) retinitis in five patients, ocular syphilis in four patients, and ocular toxoplasmosis in two patients. Uveitis resolved in all patients after medical treatment. However, a retinal detachment developed in two eyes in CMV retinitis and one eye in ocular syphilis. Ocular manifestations are among the most common clinical features in patients with HIV/AIDS who have varying clinical presentations that affect almost all ocular structures. This study demonstrated that ocular findings could be an initial manifestation of an underlying disease. Awareness of ocular lesions in HIV/AIDS is important for early recognition and management.

    In the United States, most new cases of human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) occur among women of color (primarily African American and Hispanic women). Most women of color acquire the disease from heterosexual contact, often from a partner who has undisclosed risk factors for HIV infection. Safe sex practices, especially consistent condom use, must be emphasized for all women, including women of color. A combination of testing, education, and brief behavioral interventions can help reduce the rate of HIV infection and its complications among women of color. In addition,biomedical interventions such as early treatment of patients infected with HIV and pre-exposure antiretroviral prophylaxis of high-risk individuals offer promise for future reductions in infections.

    2002-01-01

    Focal neurological disease in patients with acquired immunodeficiency syndrome may be caused by various opportunistic pathogens and malignancies, including Toxoplasma gondii, progressive multifocal leukoencephalopathy (PML), cytomegalovirus (CMV), and Epstein-Barr virus-related primary central nervous system (CNS) lymphoma. Diagnosis may be difficult, because the findings of lumbar puncture, computed tomography (CT), and magnetic resonance imaging are relatively nonspecific. Newer techniques have led to improved diagnostic accuracy of these conditions. Polymerase chain reaction (PCR) of cerebrospinal fluid specimens is useful for diagnosis of PML, CNS lymphoma, and CMV encephalitis. Recent studies have indicated the diagnostic utility of new neuroimaging techniques, such as single-photon emission CT and positron emission tomography. The combination of PCR and neuroimaging techniques may obviate the need for brain biopsy in selected cases. However, stereotactic brain biopsy, which is associated with relatively low morbidity rates, remains the reference standard for diagnosis. Highly active antiretroviral therapy has improved the prognosis of several focal CNS processes, most notably toxoplasmosis, PML, and CMV encephalitis.

    To evaluate the histomorphometric skin changes over aging patients with autopsied acquired immunodeficiency syndrome (AIDS). In 29 skin fragments of autopsied elderly (older than 50 years) and nonelderly patients with AIDS, epidermal thickness, the number of layers, the diameter of cells, the percentage of collagen and elastic fibers in the dermis, and the number and morphology of Langerhans cells were assessed. Statistical analysis was performed by SigmaStat 2.03 program. The thickness of the epidermis (92.55 × 158.94 μm), the number of layers (7 × 9 layers), and the diameter of the cells (13.27 × 17.6 μm) were statistically lower among the elderly. The quantity of collagen fibers (9.68 × 14.11%) and elastic fibers (11.89 × 15.31%) was also significantly lower in the elderly. There was a decrease in total (10.61 × 12.38 cel/mm(2)) and an increase in immature Langerhans cells (6.31 × 4.98 cel/mm(2)) in elderly patients with AIDS. The aging of the skin of patients with AIDS is amended in different histomorphometric aspects, the epidermis constituents suffer less pronounced changes in normal aging, and the dermis has more intense changes in elastic fibers and collagen.

    The Brazilian response to the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) epidemic is being observed all over the world because of its success. Understanding the role of injection drug users (IDUs) in the epidemic and the political response thereto is a key factor in the control of the epidemic in Brazil. This paper summarizes some of the most important analyses of the Brazilian response to the HIV/AIDS epidemic among and from IDUs. Key elements of the response include the support of the Brazilian Universal Public Health System, the provision of universal access to highly active antiretroviral therapy, and the creation of harm reduction projects that are politically and financially supported by the federal government. The response among and from IDUs is a key element in overall control of the HIV/AIDS epidemic. The response to the epidemic among and from IDUs has been headed in the correct direction since its beginning and is now being intensively expanded.

    Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS)-related knowledge and behaviors were assessed in face-to-face structured interviews with 314 Ethiopian military personnel. A significant finding of this research was the association between HIV/AIDS knowledge and risky sexual behavior. That is, military personnel who had inaccurate knowledge about HIV/AIDS transmission and prevention were 3.4 times as likely to engage in combined sexual risk behaviors compared with personnel with accurate knowledge, after controlling for age, military rank, and marital status (odds ratio, 3.4; 95% confidence interval, 1.86-6.22). This finding highlights the potential value of educational programs in slowing the spread of HIV/AIDS in sub-Saharan Africa.

    Neurological complications in patients with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS) are still common, even in the era of highly active antiretroviral therapy. Opportunistic infections, immune reconstitution, the virus itself, antiretroviral drugs and neurocognitive disorders have to be considered when establishing the differential diagnosis. Toxoplasmic encephalitis remains the major cause of space-occupying lesions in the brain of patients with HIV/AIDS; however, spinal cord involvement has been reported infrequently. Here, we review spinal cord toxoplasmosis in HIV infection and illustrate the condition with a recent case from our hospital. We suggest that most patients with HIV/AIDS and myelitis with enhanced spine lesions, multiple brain lesions and positive serology for Toxoplasma gondii should receive immediate empirical treatment for toxoplasmosis, and a biopsy should be performed in those cases without clinical improvement or with deterioration.

    2005-04-01

    In people infected with the human immunodeficiency virus (HIV) both the CD4 T-cell count and the viral load are used to monitor disease progression to acquired immunodeficiency syndrome (AIDS). CD4 counts of <500/mm(3) are associated with opportunistic infections and certain malignancies, so-called 'AIDS-defining' conditions. Highly active antiretroviral therapy, using combinations of reverse transcriptase inhibitors and/or protease inhibitors, can improve considerably the prognosis of people who are HIV-positive, but such therapy is not yet widely available in many developing countries. People with AIDS are predisposed to urinary tract infection (UTI) by uncommon bacteria and pathogens, e.g. fungi, parasites and viruses, which may affect any urogenital organ; treatment should be culture-specific and long-term, because there is a tendency to recurrence, infection with multiple organisms and resistant isolates. Voiding dysfunction in patients with AIDS is usually a result of neurological complications caused by opportunistic infections, and has a poor prognosis. Of patients with AIDS, 30-50% develop a cancer, especially Kaposi's sarcoma (KS) and non-Hodgkin's lymphoma (NHL). KS may involve any urogenital organ, but is usually part of systemic disease. Small lesions on the external genitalia can be treated with laser, cryotherapy or surgical excision, larger lesions with radiotherapy, and disseminated or visceral KS with multidrug chemotherapy. NHL may involve the kidneys, testes and retroperitoneal lymph nodes, thus obstructing the ureters, which may require ureteric stenting or percutaneous nephrostomy. NHL can be treated with radiotherapy and combination chemotherapy. Urolithiasis in patients with AIDS may be caused by indinavir, a protease inhibitor, but the more common types of stones may also occur. Fluid-electrolyte and acid-base disturbances are common in patients with advanced AIDS, secondary to vomiting, diarrhoea, malnutrition or septicaemia. HIV

    1985-01-01

    The infectious complications of the acquired immunodeficiency syndrome (AIDS) are discussed, and the conventional and nonconventional therapies used for these infections are reviewed. The infections most commonly encountered in patients with AIDS are Pneumocystis carinii pneumonia (58%), Candida esophagitis (31%), toxoplasmosis (21%), cytomegalovirus infections (15%), and herpes-simplex virus infections (12%). Pneumocystis carinii pneumonia is the most common life-threatening process in these patients. Trimethoprim-sulfamethoxazole (TMP-SMZ) is considered the drug of choice for its treatment. Oral candidiasis often indicates the progression to AIDS in the high-risk populations of homosexual or bisexual men, intravenous drug abusers, and individuals with hemophilia. Nystatin suspension is commonly used to treat oral candidiasis, while Candida esophagitis demands systemic therapy with ketoconazole. Toxoplasmosis most commonly manifests itself in patients with AIDS as a cerebral mass lesion. The recommended therapy includes sulfadiazine and pyrimethamine. AIDS patients frequently experience protozoal invasion of the intestinal tract with Giardia lamblia, Isospora belli, and Cryptosporidium muris. Various drugs have been tried for these infections, including quinacrine hydrochloride, metronidazole, TMP-SMZ, and spiramycin. Cytomegalovirus (CMV) infections commonly involve the lungs, gastrointestinal tract, eyes, brain, and nervous system. Attempts to treat these disseminated CMV infections with antiviral agents, including acyclovir, have not been successful. However, acyclovir has been found beneficial in the treatment of herpes-simplex virus infections. Multiple infectious complications may occur in patients with AIDS as a result of the cellular-immune deficiency associated with this disease. Until more research is done with AIDS patients, therapy must be based on the data available from the treatment of these infections in immunosuppressed patients without AIDS.

    Strategies for confronting the epidemic of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) have included a range of different approaches that focus on prevention and treatment. However, debate persists over what levels of emphasis are appropriate for the different components of the global response. This paper presents an overview of this debate and briefly summarizes the evidence on a range of interventions designed to prevent the spread of HIV infection, paying particular attention to voluntary counselling and testing, treatment for sexually transmitted infections and prevention of mother-to-child transmission. We also review the experience with antiretroviral therapy to date in terms of response rates and survival rates, adherence, drug resistance, behavioural change and epidemiological impact. Although various studies have identified strategies with proven effectiveness in reducing the risks of HIV infection and AIDS mortality, considerable uncertainties remain. Successful integration of treatment and prevention of HIV/AIDS will require a balanced approach and rigorous monitoring of the impact of programmes in terms of both individual and population outcomes.

  1. Pro- and anti-inflammatory cytokines in human immunodeficiency virus infection and acquired immunodeficiency syndrome.

    PubMed

    Breen, Elizabeth Crabb

    2002-09-01

    In persons with human immunodeficiency virus (HIV) infection and/or acquired immunodeficiency syndrome (AIDS), the immune system becomes dysfunctional in many ways. There is both immunodeficiency due to the loss of CD4-positive T helper cells and hyperactivity as a result of B-cell activation. Likewise, both decreases and increases are seen in the production and/or activity of cytokines. Cytokine changes in HIV infection have been assessed by a variety of techniques, ranging from determination of cytokine gene expression at the mRNA level to secretion of cytokine proteins in vivo and in vitro. Changes in cytokine levels in HIV-infected persons can affect the function of the immune system, and have the potential to directly impact the course of HIV disease by enhancing or suppressing HIV replication. In particular, the balance between the pro-inflammatory cytokines interleukin (IL)-1, IL-6, and tumor necrosis factor-alpha, which up-regulate HIV expression, and IL-10, which can act both as an anti-inflammatory cytokine and a B-cell stimulatory factor, may play an important role in the progression to AIDS. In light of its ability to suppress the production of pro-inflammatory cytokines and, under some conditions, suppress HIV replication, increased IL-10 may be viewed as beneficial in slowing HIV disease progression. However, an association between increased IL-10 and the development of AIDS-associated B-cell lymphoma highlights the bifunctional nature of IL-10 as both an anti-inflammatory and B-cell-stimulatory cytokine that could have beneficial and detrimental effects on the course of HIV infection and AIDS.

    Infections of the central nervous system (CNS) in individuals with human immunodeficiency virus (HIV) remain a substantial cause of morbidity and mortality despite the introduction of highly active antiretroviral therapy (HAART) especially in the resource-limited regions of the world. Diagnosis of these infections may be challenging because findings on cerebrospinal fluid (CSF) analysis and brain imaging are nonspecific. While brain biopsy provides a definitive diagnosis, it is an invasive procedure associated with a relatively low mortality rate, thus less invasive modalities have been studied in recent years. Diagnosis, therefore, can be established based on a combination of a compatible clinical syndrome, radiologic and CSF findings, and understanding of the role of HIV in these infections. The most common CNS opportunistic infections are AIDS-defining conditions; thus, treatment of these infections in combination with HAART has greatly improved survival.

    Brewster, David

    2011-09-01

    The human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) epidemic in Africa has raised important ethical issues for both researchers and clinicians. The most notorious controversy has been related to the zidovudine (AZT) trials in Africa in the late 1990s, in which the control groups were given a placebo rather than an effective drug to prevent vertical transmission. This raised concerns in the sponsoring country about exploitation of subjects, injustice and an ethical double standard between donor countries and resource-poor settings. However, the real double standard is between clinical practice standards in Western versus African countries, which must be addressed as part of the increasing global inequity of wealth both between countries and also within countries. There are important limitations to ethical declarations, principles and guidelines on their own without contextual ethical reasoning. The focus on research ethics with the HIV epidemic has led to a relative neglect of ethical issues in clinical practice. Although the scientific advances in HIV/AIDS have changed the ethical issues since the 1990s, there has also been progress in the bioethics of HIV/AIDS in terms of ethical review capability by local committees as well as in exposure to ethical issues by clinicians and researchers in Africa. However, serious concerns remain about the overregulation of research by bureaucratic agencies which could discourage African research on specifically African health issues. There is also a need for African academic institutions and researchers to progressively improve their research capacity with the assistance of research funders and donor agencies.

A one year study of toxoplasmosis prevalence was carried out among patients with acquired immunodeficiency syndrome and blood donors in Bamako. The toxoplasmosis prevalence was 60% from AIDS patients, 22.6% from the HIV-seropositive blood donors and 21% from the HIV-seronegative blood donors. The specific antibodies were IgG and IgA. The specific IgM were not detected.

    Renal syndromes associated with the Acquired immunodeficiency syndrome include: potentially reversible acute renal failure, AIDS associated nephropathy which leads to end stage renal disease, and AIDS developing in patients who are being treated by maintenance hemodialysis. The longitudinal study of 95 patients with AIDS and various forms of renal syndrome at two urban institutions indicates that both acute and chronic renal failure is increasing yearly. While some patients with acute renal failure recover renal function and survive for prolonged period, the mortality of dialyzed patients with irreversible renal failure continues to be unsatisfactory. There is a great need for collecting data from high risk areas to analyze the results of maintenance dialysis therapy in patients with AIDS, to assess the economic impact of uremia therapy, and for long-term planning of available resources.

    Glioblastoma of the brain stem is rare and there is no description of such a lesion in patients suffering from acquired immunodeficiency syndrome. The majority of intracerebral mass lesions are due either to toxoplasmosis or primary central nervous system lymphomas so that it is usually not included in the differential diagnosis of enhancing lesions of the central nervous system in these patients. A 31-year-old human immunodeficiency virus (HIV) infected man presented with a four months history of slowly progressive deterioration of brainstem associated symptoms despite antitoxoplasmic therapy. Magnetic resonance imaging revealed a large ring enhancing lesion in the brainstem. Clinical and neuroradiological data could not establish a proper diagnosis and a stereotactic serial biopsy was undertaken. Histological examination of the specimen showed a glioblastoma multiforme (GBM) as the first reported case of GBM located in the brainstem in an acquired immunodeficiency syndrome (AIDS) patient. Patient management and effectiveness of stereotactic serial biopsy are discussed.

She presented abdominal distension, dehydration, tachypnea, crackles and wheezing in both lungs, anemia, thrombocytopenia and coagulopathy. She received broad-spectrum antibiotics and exploratory laparotomy was performed with appendectomy and lymph node biopsy. After 72 hours the patient presented tonic clonic seizure, impaired sensory, fever, hypoxemia, hepatosplenomegaly, ascites and peripheral edema. She developed bicytopenia, hyperferritinemia and bone marrow microscopic examination with hemophagocytosis. She received intravenous gammaglobulin, steroids and blood transfusions. Mycobacterium tuberculosis was cultured in gastric aspirate, bone marrow and abdominal lymph node biopsy. She was treated with isoniazid, rifampicin, streptomycin and ethambutol, showing marked improvement.

    We reported a case of acquired immunodeficiency syndrome (AIDS) via multiple blood transfusions, who manifested progressive multifocal leukoencephalopathy (PML) about 18 months after the development of AIDS. PML initiated with right hemiparesis, dysphasia, and Gerstmann's syndrome and resulted in death within 2 months after the onset. Neuroimaging examinations revealed white matter lesions mainly in the left posterior parietal lobe. The cortical gray matter also showed abnormal signal intensity. Peripheral CD4+ lymphocyte count was 81/microl. Routine cerebrospinal fluid (CSF) examinations were negative. CSF antibodies against herpes simplex virus, varicella-zoster virus, cytomegalovirus, Epstein-Barr virus as well as serum antibody against toxoplasma gondii were negative. Though autopsy or biopsy of the brain was not performed, JC virus genomes were detected in the CSF sample by a polymerase chain reaction, and their sequencing showed unique alterations of the regulatory regions, characteristic to PML-type JC virus.

    Fresh stool specimens, collected at random from 63 medical in-patients with acquired immunodeficiency syndrome (AIDS), were studied prospectively for Cryptosporidium oocyst. The diagnosis of AIDS was made according to the clinical case definition of the Bangui criteria. These patients presented with profuse watery diarrhoea, significant weight loss and other associated symptoms and signs of clinical manifestations of symptomatic human immunodeficiency virus (HIV) infection. Using the modified Kinyoun acid fast staining technique, 25(39.7%) of the stool specimens were positive for Cryptosporidium oocyst. This study showed that the protozoan, Cryptosporidium parvum, may be responsible for a significant proportion of cases of chronic diarrhoea among AIDS patients in Ethiopia.

    Varicella zoster virus (VZV) immunization aids in the prevention of future VZV infections in immunocompetent patients; however, severely immunocompromised patients remain at increased risk of VZV infection. We report a case of a 10-year-old boy previously immunized to Varicella who presented with herpes zoster with hematogenous dissemination as the Acquired Immunodeficiency Syndrome-defining illness. Disseminated VZV is more commonly seen in human immunodeficiency virus (HIV)-infected individuals with more advanced disease, as was the case with our patient. Disseminated VZV infection in a previously immunized child should raise suspicion for underlying immunosuppression.

    Cerebral toxoplasmosis commonly affects patients with advanced HIV immunodeficiency. Toxoplasmosis in patients who are immunocompromised can be severe and debilitating in patients with Central Nervous System (CNS) involvement and the condition may be fatal. We report the case of a 40-year-old man who was a known case of HIV and presented with cerebral toxoplasmosis. His Magnetic Resonance Imaging (MRI) scan showed multiple ring enhancing lesions with extensive surrounding oedema in supratentorial as well as infratentorial region. Lesions were mainly located in the periventricular region as well as at the grey-white matter junction and showed enhancement in the periphery as well as a tiny nodular enhancement in the centre. Patient was started on Septran DS, empirically for toxoplasmosis and steroids to reduce intracranial pressure. On follow up MRI scan after 10 days there was a reduction in size, number and enhancement of the masses with decrease in the surrounding oedema. Patient was clinically stable, oriented and his fever settled. He was discharged from hospital on same medication and advised to continue regular follow-up.

    Although Toxoplasma gondii frequently causes lesions of the central nervous system in AIDS, the exact incidence of extracerebral toxoplasmosis in these immunodepressed patients remains difficult to determine. Isolation of the parasite outside the central nervous system is rarely performed ante mortem, and most diagnoses of extracerebral toxoplasmosis are made post mortem. This article describes 23 cases of extracerebral toxoplasmosis diagnosed between 1987 and 1991 in an autopsy series of 170 patients infected with the human immunodeficiency virus (HIV). Ante mortem diagnosis of extracerebral involvement was affirmed in 4 of these 23 patients by identification of trophozoites in bronchoalveolar lavage fluid (2 cases), a surgical pulmonary biopsy specimen, and a bladder biopsy. Clinical and paraclinical findings suggested cardiac involvement in 4 other patients. Post mortem examination demonstrated disseminated toxoplasmosis in 18 cases and extracerebral monovisceral involvement in 5 cases. Extracerebral toxoplasmosis was directly responsible for the death of 6 patients. The most frequent extracerebral sites of Toxoplasma gondii involvement were the heart (21/23 cases; 91%), the lungs (14/23 cases; 61%) and the pancreas (6/23 cases; 26%). The tissular consequences of toxoplasmic involvement varied considerably, from formation of pseudocysts or cysts without any surrounding inflammatory reaction to necrotic lesions rich in neutrophilic polynuclear cells containing numerous free parasites. Immunoperoxidase study using antitoxoplasmic antibodies contributed to the diagnosis of 8 extracerebral localizations. Electron microscopy examination of a surgical lung biopsy and myocardial specimens (2 cases) demonstrated the ultrastructural characteristics of Toxoplasma gondii trophozoites.(ABSTRACT TRUNCATED AT 250 WORDS)

    In this study the authors describe a non-Hodgkin's lymphoma histologically typed "large non-cleaved cell immunophenotype B cell", placed primitively into the liver. It affected a woman twenty seven years old, who contracted HIV infection due to heterosexual intercourse with at risk partner. At the time of diagnosis the woman was already considered AIDS patient on account of a previous Pneumocystis carinii pneumoniae and severe immunodeficiency (DC4 = 13 cells/mm3). The patient received cycles of chemotherapy (adriamycin 40 mg/iv, teniposide 50 mg/iv, cyclophosphamide 500 mg/iv, vincristine 2 mg/iv, bleomycin 15 mg/iv, betamethasone 4 mg/iv). At the 15th day of therapeutic cycle vincristine 2 mg/iv, bleomycin 15 mg/iv and betamethasone 4 mg/iv were given. After one cycle of therapy, hepatic echography showed signs that the lymphoma was reduced significantly. The authors stress the uncommon non-Hodgkin lymphoma localization, which is frequently underestimated in HIV-patients.

    The clinicopathologic features of 4 AIDS patients with cutaneous colesional Kaposi sarcoma (KS) and cryptococcosis, a rare phenomenon, are described. Biopsies from 3 patients who were highly active antiretroviral therapy (HAART)-naive demonstrated predominant KS with a conspicuous spindle cell component and small aggregates of cryptococcal yeasts in 2 biopsies and predominant gelatinous cryptococcosis with attenuated KS spindle cells in 1 biopsy. One patient was HAART exposed. He had childhood pulmonary tuberculosis, was treated for disseminated cutaneous cryptococcosis 18 months earlier and presented with cutaneous lesions, odynophagia and massive cervical lymphadenopathy in the eighth week of HAART, after achieving viral suppression and a CD4 cell increase from 28 to 184 cells/μL. His skin biopsy demonstrated a dense lymphoplasmacytic infiltrate, neutrophils, and granulomas with admixed aggregates and single Cryptococcus neoformans and focal aggregation of human herpes virus 8-immunopositive spindle cells. Acid fast bacilli were not identified and mycobacterial molecular studies were negative. The features were compatible with cutaneous cryptococcal immune reconstitution inflammatory syndrome. His nodal and oropharyngeal biopsies demonstrated dense mixed, including granulomatous, inflammation with few cryptococcal yeasts and acid fast bacilli, confirmed to be Mycobacterium tuberculosis on polymerase chain reaction testing, without KS. These features were also compatible with immune reconstitution inflammatory syndrome, but the exact role of each infection in the extracutaneous sites was unconfirmed. Colesional KS and cryptococcosis served as the sentinel lesion of AIDS in 3 patients and of immune reconstitution inflammatory syndrome in 1 patient.

    To assess the utility of the National Death Index (NDI) in improving the ascertainment of deaths among people diagnosed with acquired immunodeficiency syndrome (AIDS), the authors determined the number and characteristics of additional deaths identified through NDI linkage not ascertained by using standard electronic linkage with Florida Vital Records and the Social Security Administration's Death Master File. Records of people diagnosed with acquired immunodeficiency syndrome between 1993 and 2007 in Florida were linked to the NDI. The demographic characteristics and reported human immunodeficiency virus (HIV) transmission modes of people whose deaths were identified by using the NDI were compared with those whose deaths were ascertained by standard linkage methods. Of the 15,094 submitted records, 719 had confirmed matches, comprising 2.1% of known deaths (n = 34,504) within the cohort. Hispanics, males, people 40 years of age or older, and injection drug users were overrepresented among deaths ascertained only by the NDI. In-state deaths comprised 59.0% of newly identified deaths, and human immunodeficiency virus was less likely to be a cause of death among newly identified compared with previously identified deaths. The newly identified deaths were not previously ascertained principally because of slight differences in personal identifying information and could have been identified through improved linkages with Florida Vital Records.

    In Spain, approximately 10 years passed between the time when human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) harm-reduction programs should have been developed with sufficient coverage to have an optimum impact on public health (before the HIV/AIDS epidemic's explosion in 1984) and the date of their actual implementation. This delay yielded an enormous cost for the country. The introduction of the virus in drug injector networks during a period of widespread diffusion of heroin injection and the lack of political awareness of the growing problem were 2 important factors that contributed to the important diffusion of the HIV infection among Spanish injection drug users. Lessons can be learned that may be of great interest in countries or territories facing similar challenges now and in the future.

    Urinary excretion of modified nucleosides and beta-aminoisobutyric acid, subsequently referred to as markers, was determined in populations of patients with acquired immunodeficiency syndrome (AIDS) or at risk for development of AIDS. Our results show that asymptomatic adult male homosexuals excreted elevated amounts of markers as compared to male heterosexuals. This aberrant excretion was more pronounced in asymptomatic adult male homosexuals with antibodies to HTLV-III. Significantly greater excretion of 1-methylinosine, N4-acetylcytidine, and N2-methylguanosine was observed in asymptomatic adult male homosexuals with antibodies to HTLV-III than in asymptomatic male homosexuals without antibodies to HTLV-III. Increased amounts of markers were also excreted by subjects with the generalized or chronic lymphadenopathy syndrome, AIDS related complex (ARC), or AIDS. In these subjects, the most pronounced differences between groups were between subjects with chronic lymphadenopathy syndrome and those with ARC; subjects with ARC excreted greater amounts of seven of the ten urinary markers. There were few differences between subjects with ARC and those with AIDS, Kaposi's sarcoma, or AIDS with opportunistic infections. This observation may be useful for identifying subjects who are at risk of developing AIDS. A prospective study to test this hypothesis is under way.

    At least 6 million people in the Asia-Pacific region have human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome (AIDS). The numbers of HIV-infected women and children are increasing at an alarming rate. Important components of infection control that need to be addressed if mother-to-child transmission of HIV is to be prevented successfully include voluntary and confidential counseling and testing, family planning, obstetric care, use of antiretroviral agents, and availability of alternatives to breast-feeding. Many services can aid in the prevention of mother-to-child transmission of HIV and the care of HIV-infected mothers and their children. Each country needs to take into account the features of HIV and AIDS epidemiology that are peculiar to it, its infrastructure, and the resources that are available. Providing services in a stepwise manner can help prevent mother-to-child transmission of HIV.

    Chinese medicine (CM) has been used in the treatment of human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) for 30 years and the demonstrated therapeutic effects of CM, such as reducing plasma HIV viral load, increasing CD4(+)T cell counts, promoting immunity reconstitution, ameliorating symptoms and signs, improving the health related quality of life (HRQOL) and counteracting against the effects of anti-retroviral drugs, were summarized and reviewed in this article. The authors point out that it had been a good opportunity to use CM for the treatment of HIV infection and AIDS in the past and also there are huge challenges ahead for CM research and clinicians to discover more effective CM and its underlying mechanisms for treatment of AIDS.

    Acquired immunodeficiency syndrome (AIDS), caused by human immunodeficiency virus (HIV), has become, because of the rapid spread of the disease, a serious global problem and cannot be treated. Recent studies indicate that VIF is a protein of HIV to prevent all of human immunity to attack HIV. Molecular compounds of traditional Chinese medicine (TCM) database filtered through molecular docking and molecular dynamics simulations to inhibit VIF can protect against HIV. Glutamic acid, plantagoguanidinic acid, and Aurantiamide acetate based docking score higher with other TCM compounds selected. Molecular dynamics are useful for analysis and detection ligand interactions. According to the docking position, hydrophobic interactions, hydrogen bonding changes, and structure variation, the study try to select the efficacy of traditional Chinese medicine compound Aurantiamide acetate is better than the other for protein-ligand interactions to maintain the protein composition, based on changes in the structure.

    Pancreatic tuberculosis (TB) is a relatively rare disease that can mimic carcinoma, lymphoma, cystic neoplasia, retroperitoneal tumors, pancreatitis or pseudocysts. Here, I report the case of a 31-year-old immigrant Burmese woman who exhibited epigastralgia, fever, weight loss and an epigastric mass. The patient was diagnosed with pancreatic TB and acquired immunodeficiency syndrome, and was treated with antituberculous drugs and percutaneous catheter drainage without a laparotomy. The clinical presentation, radiographic investigation and management of pancreatic TB are summarized in this paper to emphasize the importance of considering this rare disease in the differential diagnosis of pancreatic masses concomitant with human immunodeficiency virus infection. I also emphasize the need for both histopathological and microbiological diagnosis via fine-needle aspiration.

    Thirty-two patients with AIDS related complex (ARC) or acquired immunodeficiency syndrome (AIDS) underwent /sup 67/Ga scans as part of their evaluation. Three patterns of /sup 67/Ga biodistribution were found: lymph node uptake alone; diffuse pulmonary uptake; normal scan. Gallium-67 scans were useful in identifying clinically occult Pneumocystis carinii pneumonia in seven of 15 patients with ARC who were asymptomatic and had normal chest radiographs. Gallium scans are a useful ancillary procedure in the evaluation of patients with ARC or AIDS.

    The challenge of the acquired immunodeficiency syndrome (AIDS) for nuclear medicine has been the early detection of related intrathoracic opportunistic infections, inflammatory conditions, and neoplasms. Gallium-67 citrate scanning has proved a sensitive test not only for Pneumocystis carinii pneumonia but for many of the other opportunistic infections and malignancies, including mycobacterial infections and lymphoma. Patterns and intensity of gallium uptake may suggest more specific diagnoses. Indium-111-labeled white blood cells may also be a valuable diagnostic tool in the AIDS patient.41 references.

Definitive diagnosis was confirmed by direct microscopic examination, which revealed numerous Sarcoptes scabei. Dermoscopy showed pathognomonic scabetic burrows and brownish structures in the shape of a hand-glider with a millipede-like appearance. The latter constitutes a diagnostic feature in the pathology of Norwegian scabies that has not yet been described. The patient responded well to oral ivermectin and topical vaseline with sulphur at a proportion of 10%. There was a simultaneous improvement in dermoscopic parameters.

    Clinical features of 49 episodes of Pneumocystis carinii pneumonia in patients with the acquired immunodeficiency syndrome were compared with those of 39 episodes in patients with other immunosuppressive diseases. At presentation patients with the syndrome were found to have a longer median duration of symptoms (28 days versus 5 days, p = 0.0001), lower mean respiratory rate (23.4 versus 30, p = 0.005), and higher median room air arterial oxygen tension (69 mm Hg versus 52 mm Hg, p = 0.0002). The survival rate from 1979 to 1983 was similar for the two groups (57% and 50% respectively). Patients with the syndrome had a higher incidence of adverse reactions to trimethoprim-sulfamethoxazole (22 of 34 versus 2 of 17, p = 0.0007). Survivors with the syndrome at initial presentation had a significantly lower respiratory rate, and higher room air arterial oxygen tension, lymphocyte count, and serum albumin level compared to nonsurvivors. Pneumocystis carinii pneumonia presents as a more insidious disease process in patients with the syndrome, and drug therapy in these patients is complicated by frequent adverse reactions.

    Human immunodeficiency virus (HIV) infection is associated with increased intestinal translocation of microbial products and enteropathy as well as alterations in gut bacterial communities. However, whether the enteric virome contributes to this infection and resulting immunodeficiency remains unknown. We characterized the enteric virome and bacterial microbiome in a cohort of Ugandan patients, including HIV-uninfected or HIV-infected subjects and those either treated with anti-retroviral therapy (ART) or untreated. Low peripheral CD4 T cell counts were associated with an expansion of enteric adenovirus sequences and this increase was independent of ART treatment. Additionally, the enteric bacterial microbiome of patients with lower CD4 T counts exhibited reduced phylogenetic diversity and richness with specific bacteria showing differential abundance, including increases in Enterobacteriaceae, which have been associated with inflammation. Thus, immunodeficiency in progressive HIV infection is associated with alterations in the enteric virome and bacterial microbiome, which may contribute to AIDS-associated enteropathy and disease progression.

    During a 4.4-year period, nonspecific interstitial pneumonitis was seen in 41 of 110 (38%) patients with the acquired immunodeficiency syndrome and accounted for 32% (48/152) of all episodes of clinical pneumonitis. Diffuse alveolar damage was typically a feature of nonspecific interstitial pneumonitis, but neither lung biopsy nor bronchoalveolar lavage detected a pathogen. Of these 41 patients, 13 had no associated pulmonary tumor and had not been exposed to pulmonary toxins, whereas 28 patients had either concurrent pulmonary Kaposi sarcoma, previous experimental therapies, or a history of pneumocystis pneumonia or drug abuse. Of these 41, 23 had normal chest radiographs. The clinical features of patients with nonspecific interstitial pneumonitis were similar to those of patients with pneumocystis pneumonia, although histologic findings showed less severe alveolar damage in patients with nonspecific interstitial pneumonitis (p less than 0.001). Pathologic evaluation and clinical follow-up suggest that many clinical episodes of pneumonitis in patients with the acquired immunodeficiency syndrome are due to nonspecific interstitial pneumonitis of unknown cause.

    Objective: This study aimed to determine whether the human immunodeficiency virus (HIV) exists in giant idiopathic esophageal ulcers in the patients with acquired immune deficiency syndrome (AIDS). Methods: 16 AIDS patients with a primary complaint of epigastric discomfort were examined by gastroscopy. Multiple and giant esophageal ulcers were biopsied and analyzed with pathology staining and reverse transcription-polymerase chain reaction (RT-PCR) to determine the potential pathogenic microorganisms, including HIV, cytomegalovirus (CMV) and herpes simplex viruses (HSV). Results: HIV was detected in ulcer samples from 12 out of these 16 patients. Ulcers in 2 patients were infected with CMV and ulcers in another 2 patients were found HSV positive. No obvious cancerous pathological changes were found in these multiple giant esophageal ulcer specimens. Conclusion: HIV may be one of the major causative agents of multiple benign giant esophageal ulcers in AIDS patients. PMID:27830031

    We studied 52 patients with disseminated histoplasmosis, 30 with the acquired immunodeficiency syndrome (AIDS) (cohort 1) and 22 not co-infected with the human immunodeficiency virus (cohort 2). Demographic, clinical, laboratory, mycologic findings, as well as antifungal therapy and highly active antiretroviral (HAART), were analyzed. Skin lesions were significantly higher in cohort 1 than in cohort 2 (P = 0.001). Anemia, leukopenia, and an elevated erythrocyte sedimentation rate were also more pronounced in cohort 1 than in cohort 2 (P < 0.001). Histoplasma capsulatum was isolated more often in cohort 1 than in cohort 2 (P < 0.05) patients, but antibodies to H. capsulatum were detected more frequently in cohort 2 than in cohort 1 (P < 0.05). Itraconazole treatment was less effective in cohort 1 than in cohort 2 (P = 0.012). In cohort 1 patients, HAART improved response to antifungals when compared with individuals not given HAART (P = 0.003), who exhibited higher mortality rates (P = 0.025). Cohort 1 patients who were given dual antifungal and anti-retroviral therapies responded as well as the non-HIV patients in cohort 2, who were treated only with itraconazole. These results indicate the need to promote restoration of the immune system in patients with AIDS and histoplasmosis.

    Histoplasmosis has attained increasing relevance in the past 3 decades because of the appearance of the human immunodeficiency virus (HIV). In most immunocompetent persons, the infection is asymptomatic or can produce a respiratory condition with symptoms and radiological images similar to those observed in pulmonary tuberculosis; in non-HIV+ immunocompromised patients, it can cause respiratory symptoms or evolve into a disseminated infection. The same can occur in acquired immunodeficiency syndrome (AIDS) patients. We have observed a series of HIV+ patients with AIDS who presented with cutaneous histoplasmosis and in whom the clinical and histopathological features were highly unusual, including variable mucocutaneous lesions that were difficult to diagnose clinically. These patients displayed unusual, previously undescribed, histological patterns, including lichenoid pattern, nodular pseudomyxoid pattern, pyogenic granuloma-like pattern, perifollicular pattern, and superficial (S), mid (M), and deep perivascular dermatitis; and more commonly encountered patterns, such as histiocytic lobular panniculitis and focal nodular dermatitis. The novel histopathological patterns of cutaneous involvement by histoplasmosis seen in these patients resembled other common inflammatory and infectious conditions and required a high level of suspicion and the application of special stains for organisms for confirmation. These new, clinical, and histological findings do not seem to be commonly encountered in HIV- patients infected with the fungus but seem to be displayed most prominently in HIV+ patients with AIDS.

    As newer methods of management are made available, and accessible, survival rates with human immunodeficiency virus (HIV) are increasing. This means that chronic, metabolic complications of HIV are becoming more frequent in clinical practice, as acute morbidity is controlled. Management of HIV/acquired immunodeficiency syndrome (AIDS) is gradually expanding to include these chronic and metabolic complications of the disease, and the adverse effects associated with its treatments, including diabetes. Unfortunately, no guidelines are available to help the medical practitioners choose appropriate therapy for patients with these conditions. The aim of the South Asian Consensus Guidelines is to provide evidence-based recommendations to assist healthcare providers in the rational management of type 2 diabetes mellitus in patients with HIV. The development of these guidelines used systematic reviews of available evidence to form its key recommendations. These guidelines and associated review of literature represent a compilation of available knowledge regarding rational management of diabetes in HIV. Patients of diabetes with concomitant HIV infection are managed optimally with insulin therapy and judicious use of highly active antiretroviral therapy with suitable alternatives is also recommended. These guidelines should prove helpful to physicians, not only in South Asia, but also across the globe, while managing patients with coexistent HIV and diabetes. PMID:22028994

    We studied the frequency with which unexplained oral candidiasis led to unequivocal acquired immunodeficiency syndrome (AIDS) in patients at risk. Twenty-two previously healthy adults with unexplained oral candidiasis, of whom the 19 tested had a reversed T4/T8 ratio and 20 had generalized lymphadenopathy, were compared with 20 similar patients with a reversed T4/T8 ratio and generalized lymphadenopathy who did not have oral candidiasis. All were intravenous-drug abusers, homosexual or bisexual men, or both. Thirteen of the 22 patients with oral candidiasis (59 per cent) acquired a major opportunistic infection or Kaposi's sarcoma at a median of three months (range, 1 to 23) as compared with none of 20 patients with generalized lymphadenopathy and immunodeficiency but without candidiasis who were followed for a median of 12 months (range, 5 to 21) (P less than 0.001). AIDS developed in 12 of 15 patients with candidiasis and T4/T8 ratios less than or equal to 0.51, as compared with none of four with ratios equal to or greater than 0.60 (P less than 0.01). We conclude that in patients at high risk for AIDS, the presence of unexplained oral candidiasis predicts the development of serious opportunistic infections more than 50 per cent of the time. Whether the remainder will have AIDS is not yet known.

    More than 40 million people are infected with human immunodeficiency virus (HIV), and a successful vaccine is at least a decade away. Although highly active antiretroviral therapy prolongs life, the maintenance of viral latency requires life-long treatment and results in cumulative toxicities and viral escape mutants. Gene therapy offers the promise to cure or prevent progressive HIV infection by interfering with HIV replication and CD4+ cell decline long term in the absence of chronic chemotherapy, and approximately 2 million HIV-infected individuals live in settings where there is sufficient infrastructure to support its application with current technology. Although the development of HIV/AIDS gene therapy has been slow, progress in a number of areas is evident, so that studies to date have significantly advanced the field of gene-based immunotherapy. Advances have helped to define a series of ongoing and planned trials that may shed light on potential mechanisms for the successful clinical gene therapy of HIV.

    Although brain has been the most common site for toxoplasma infection in acquired immunodeficiency syndrome patients, involvement of spinal cord by toxoplasma has been rarely found. Spinal cord toxoplasmosis can present as acute onset weakness in both lower limbs associated with sensory and bladder dysfunction. A presumptive diagnosis can be made in patients with CD4 count <100/mm(3) based on a positive serum Toxoplasma gondii IgG antibodies, no recent prophylaxis against toxoplasmosis, intramedullary ring enhancing lesion in spinal cord supported by similar lesions in brain parenchyma. Institutions of antitoxoplasma treatment in such patients result in prompt clinical response and therefore avoiding the need of unnecessary invasive diagnostic tests. Here, we report a case of toxoplasmic myelitis in immunocompromised patient presenting as myelopathy who showed significant clinical improvement after starting antitoxoplasma treatment. Hence toxoplasmic myelitis should be considered in toxoplasma seropositive immunocompromised patients presenting as myelopathy and imaging studies showing ring enhancing intramedullary lesion.

    Toxoplasmosis and lymphoma are the two most common causes of intraparenchymal cerebral mass lesions in patients with acquired immunodeficiency syndrome (AIDS). The clinical and radiographic features of the intracranial lesions have been well described. Because of the high frequency of toxoplasmosis in the AIDS population, common therapy for patients presenting with intracranial mass lesions consists of an empirical trial of anti-Toxoplasma chemotherapy, with biopsy reserved for cases demonstrating features considered to be more consistent with lymphoma, or for lesions that do not improve despite adequate anti-Toxoplasma treatment. A similar treatment algorithm does not exist for intramedullary lesions of the spinal cord. The authors describe a patient who presented with paraparesis resulting from an isolated thoracic intramedullary lesion. An open biopsy of the lesion revealed characteristic structures containing Toxoplasma tachyzoites. The clinical and radiographic presentation of the lesion is discussed, the available literature is reviewed, and a treatment strategy for spinal cord lesions in AIDS patients is proposed.

    Automated N-terminal microsequencing of immune affinity-purified acquired immunodeficiency syndrome retrovirus polypeptides from infected cells was used to locate the N termini of 64-, 51-, and 34-kilodalton (kDa) polypeptides within the pol open reading frame (ORF) of the proviral DNA. The 64- and 51-kDa proteins had identical N termini (Pro-Ile-Ser-Pro-IIe-Glu-Thr-Val-) positioned 156 residues from the beginning of the pol ORF. The N terminus of the 34-kDa pol gene product, Phe-Leu-Asp-Gly-Ile-Asp-Lys-, mapped 716 residues into the pol ORF. These polypeptides were absent in an RT-negative, CD4-negative, persistently infected cell line (8E5) carrying a single defective copy of a constitutively expressed, integrated proviral DNA.

    Disseminated cutaneous histoplasmosis is an opportunistic infection in patients with acquired immunodeficiency syndrome. We report a series of 23 cases (21 men, two women; median age 29 years) with disseminated cutaneous histoplasmosis seen at two hospital centres. Most of the patients (21/23) were classified as stage C3. The most common dermatological findings were papules, crusting plaques, nodules and ulcers, mainly located on the face and chest. Of the 23 cases, 15 (65%) had pulmonary involvement. Amphotericin B and itraconazole were the main drugs used for treatment. Treatment response was variable: four of the patients were cured, six improved and remain stable, nine patients died, and four patients were lost to follow-up.

    We report on a 29-year-old severely compromised acquired immunodeficiency syndrome patient who developed retrobulbar optic neuritis 5 weeks after an episode of cutaneous herpes zoster infection. During the optic neuritis, varicella zoster virus could be demonstrated in the cerebrospinal fluid. The neuritis responded well to treatment with foscarnet, but, 3 weeks into therapy, varicella zoster retinitis developed. Additional treatment with intravenous acyclovir stopped progression of the retinitis and resulted in healing of the retinal lesions. This case suggests that retrobulbar optic neuritis can be regarded as a prodrome of imminent acute retinal necrosis. Early recognition and prompt therapy with combined antivirals may prevent the development of this devastating ocular complication of varicella zoster infection.

    Eighty-six (/sup 67/Ga)citrate chest scans were performed in 71 adult patients with the acquired immunodeficiency syndrome. Forty-five of these patients also had Kaposi's sarcoma. Only 29 of 57 abnormal scans were correlated with abnormal chest radiographs. Chest radiographs were negative for 27 scans and unavailable for one. Several scan patterns were seen. Diffusely increased lung uptake was seen most commonly with Pneumocystis carinii pneumonia, but also other infections and noninfectious inflammatory conditions. Focal uptake corresponding to regional lymph node groups occurred most often with Mycobacterium avium-intracellulare but aslo with lymphoma. Localized intrapulmonary uptake was seen in bacterial pneumonias. Perihilar activity occurred in two cases. When chest radiographs were abnormal and /sup 67/Ga scans negative, the most common diagnosis was pulmonary Kaposi's sarcoma.

    Kaposi's sarcoma (KS) is a malignant vascular neoplasm characterized, in its classical form, by a slow evolutive course, beginning in the lower extremities. Lately have been reported more and more cases of this entity associated with the acquired immunodeficiency syndrome (AIDS), running much more aggressively. In ENT-pathology are not uncommon this kind of neoplasm in the oral cavity and oropharynx. However at larynx's level such descriptions till now had been sporadic. The AA. present a KS case sitting in the epiglottis of an AIDS patient. They emphasize the importance of a throughout ENT-examination of these patients and also remark the necessity of performing various and deep biopsies in order to gain a diagnosis that can be relied on. Finally, they review the updated management alternatives for this sort of pathology.

    Two heterosexual men, aged 31 and 40 years, with the acquired immunodeficiency syndrome and presenting with the acute form of Chagas' disease are reported. The first patient, a carrier of hemophilia A, was treated for 20 years with Chilean and Brazilian cryoprecipitates. This patient acquired both diseases through this medium. The second patient, an inhabitant of northern Chile (fourth region), was allegedly bitten by Triatoma infestans and was an intravenous drug addict. The hemophilic patient presented with a neurologic syndrome; a brain biopsy showed a necrotizing encephalitis with an obliterative angiitis and abundant macrophages. The second patient developed intractable congestive heart failure; necropsy showed a dilated myocarditis with rupture of myofibers and an inflammatory infiltrate rich in plasma cells, lymphocytes, and macrophages. Using light and electron microscopy, abundant amastigotes of Trypanosoma cruzi were seen in brain tissue, especially in the cytoplasm of macrophages, as well as in some myocardial fibers. In both cases, determination of anti-T cruzi antibodies (indirect hemagglutination technique) and xenodiagnosis were positive.

    On January 1, 1993, the case definition of the acquired immunodeficiency syndrome (AIDS) in adults and adolescents used for monitoring the AIDS epidemic in California was expanded to include persons infected with the human immunodeficiency virus (HIV) with CD4 T-lymphocyte counts of less than 200 x 10(6) per liter (< 200 per mm3), pulmonary tuberculosis, recurrent pneumonia, or invasive cervical cancer. To assess the implications of this revision on AIDS case reporting in California, we compared cases reported through the end of 1994 based on 1 or more of the 4 new AIDS-defining conditions added in 1993 to cases reported based on pre-1993 AIDS-defining opportunistic infections and cancers. The 4 new conditions included in the 1993 expanded AIDS case definition accounted for a 23% increase in cumulative AIDS cases reported in California by the end of 1993, a 170% increase in the number of cases reported during 1993, and an 88% increase in the number of patients with AIDS living at the end of 1993. The number of cases reported in 1993 (19,629) was 124% more than that reported in 1992 (8,780) and 69% more than that reported in 1994 (11,587). The proportion of cases among women, injection-drug users, and African Americans also increased as a result of this change in the case definition. The expansion of the case definition may have resulted in a peak or plateau in the AIDS incidence in California because of reporting earlier in the HIV disease progression. The expanded case definition has enhanced the usefulness of AIDS surveillance data for targeting secondary prevention efforts, but more behavioral and HIV serosurveys are still needed to adequately target primary HIV prevention efforts.

    Background: Human immunodeficiency virus (HIV) pandemicity is a major concern today as it causes greater loss of productivity than any other disease. HIV infection leads to profound immune deficiency and patients become highly susceptible to opportunistic infections (OIs). HIV epidemic in India is heterogeneous in nature, both in terms of routes of transmission as well as geographical spread. Aims: (1) Determine prevalence of OIs among HIV-seropositive patients and their relation to CD4 count and to focus on the routes of transmission. (2) Analyze the route of transmission. Methods: This is a single-center prospective study including all the patients attending acquired immunodeficiency syndrome (AIDS) care center during the period of January 2014 to December 2014. Results: Among 71 patients included in this study, mean age was 30 years, 57.7% (41 patients) were male, 42.3% (30 patients) were female. Mean CD4 cell count of the study group was 260.11 and of patients on antiretroviral therapy increased subsequently to 553.37 cells/ml. Among the infections, the prevalence of candidiasis, tuberculosis (TB), tinea infections, seborrheic dermatitis, giardiasis, cryptosporidiosis, and Entamoeba histolytica were 36.6%, 29.58%, 4.22%, 2.82%, 4.22%, 1.4%, and 1.4%. Most predominant routes were heterosexual transmission at 94.3%. It was followed by vertical transmission seen in 2.8%. Homosexual transmission is 1.4% and intravenous drug abuse 1.4%. Conclusion: The frequency of infections among HIV/AIDS patients has got a similar linear relation with CD4 cell count. This study reports data will serve as a matrix for future evaluation. It is concluded that candidiasis, TB are the most common infections in the HIV-seropositive patients in the present study group. PMID:27890948

    With the incidence of patients infected with human immuno-deficiency virus (HIV) increasing in India, the central nervous system (CNS) manifestations of the disease will be seen more frequently. The CNS may be primarily afflicted by the virus or by opportunistic infections and neoplasms secondary to the immune suppression caused by the virus. In India, although mycobacterium tuberculosis has been reported to be the most common opportunistic infection, toxoplasmosis may become as common owing to the ubiquitous nature of the protozoan. Since an empirical trial of medical therapy without histopathological diagnosis is recommended, the true incidence of this condition may remain under estimated. The role of ancillary tests such as radiology and serology in the initial diagnosis of this condition remain crucial. This report highlights two patients who were diagnosed to have acquired immuno-deficiency syndrome (AIDS) only after the biopsy of the intracranial lesion was reported as toxoplasmosis. Presently all patients for elective neurosurgery are tested for HIV antigen. The management protocol to be followed in a known patient with AIDS presenting with CNS symptoms is discussed in detail. The value of ancillary tests is also reviewed.

    Since the beginning of the acquired immunodeficiency syndrome (AIDS) epidemic, malignancies have been an important feature of this disease. Several cancers, including Kaposi sarcoma (KS), certain aggressive B-cell lymphomas, and cervical cancer, are considered AIDS-defining when they occur in patients infected with human immunodeficiency virus. Most AIDS-defining tumors are associated with one of 3 DNA viruses: KS-associated herpesvirus, Epstein-Barr virus, or human papillomavirus. With the introduction of highly active antiretroviral therapy (HAART), the incidence of KS and certain lymphomas has decreased, whereas that of other tumors, such as cervical cancer, has undergone little change. Several new drugs and therapies have been developed for KS and AIDS-related lymphomas, and these treatments, plus the development of HAART, have contributed to improvements in morbidity and mortality. At the same time, the improved overall survival of patients with HAART has contributed to an increase in the number of patients living with AIDS in developed countries such as the United States. With the development of HAART and improved prevention and treatment of opportunistic infections, an increasing percentage of the deaths in AIDS patients have been from malignancies. Strategies for prevention, screening, and therapy remain important areas of research in this developing field.

    Since prevalent cohorts may be biased by the duration of human immunodeficiency virus (HIV) infection (onset bias), it is useful to assess the potential predictive value of markers in incident cohorts of HIV-positive subjects for whom the date of seroconversion is known or can reliably be estimated. Of 131 homosexual men with HIV-1 seroconversion from New York City and Washington, DC, who were evaluated annually beginning in 1982, 60 developed acquired immunodeficiency syndrome (AIDS) by the end of 1989. The prognostic significance of immunologic markers (proportion of CD4+ T-lymphocytes, neopterin, beta 2-microglobulin, serum interferon, and anti-p24 antibody) and of a virologic marker (HIV p24 antigen) was determined using measurements made at defined time intervals after the known or estimated date of HIV seroconversion. When measurements made 3 years after seroconversion were used, all markers except anti-p24 antibody were found to be significant estimators of AIDS risk in univariate analyses. In multivariate Cox regression modeling, the maximum information was obtained by including neopterin, interferon, and the CD4+ T-lymphocyte proportion. The predictive value of markers after HIV seroconversion could change considerably from one interval to another. Elevated levels of beta 2-microglobulin and neopterin significantly predicted the development of Kaposi's sarcoma. These two markers were highly correlated (r = 0.74). The authors conclude that immunologic markers can be important for an HIV staging system for estimating prognosis and facilitating early therapeutic intervention in HIV-positive patients.

    Cystoisospora belli in patients with the acquired immunodeficiency syndrome (AIDS) has been described as cause of chronic diarrhea and disseminated cystoisosporosis. Diagnosis of intestinal cystoisosporosis can be achieved at the tissue level in the villus epithelium of the small bowel. Disseminated cystoisosporosis is diagnosed by microscopy identification of unizoite tissue cysts in the lamina propria of the intestine. We report a case of disseminated cystoisosporosis in a human immunodeficiency virus (HIV)-infected patient with detection of parasitemia. We studied a 39-year old patient with AIDS and chronic diarrhea by analysis of stool and duodenal biopsy samples. Blood samples were also collected and examined by light microscopy and molecular techniques for C. belli DNA detection. The unizoite tissue cyst stages were present in the lamina propria, with unsporulated oocysts in feces. Zoites were present in blood smears and DNA of C. belli was detected in blood samples. Our study identified a new stage in the life cycle of C. belli. Detection of parasitemia is a novel and noninvasive tool for diagnosis of disseminated cystoisosporosis.

    We studied the effects of sera from patients with the acquired immunodeficiency syndrome (AIDS) on interleukin-2 (IL-2) production to help elucidate the mechanism of immunodeficiency. Compared with sera from healthy controls, sera from AIDS patients suppressed phytohemagglutinin (PHA)-induced IL-2 production by normal blood mononuclear cells. Sera from homosexual contacts of AIDS patients and from adults with acute cytomegalovirus infection generally lacked this suppressive activity. The effect of the AIDS sera could not be attributed to absence of a stimulatory or nutritive factor, to inactivation of IL-2, to inhibition of the IL-2 assay, nor to increased turnover of IL-2. The suppressive effect of the sera was not mediated by radiosensitive or T8 antigen-bearing suppressor cells or by increased prostaglandin production or decreased interleukin-1 production. The sera acted directly on the groups of cells that produce IL-2, T cells and large granular lymphocytes; suppression occurred at an early, probably pretranslational, stage. When cells were incubated with AIDS sera and then washed, the suppressive effect persisted. The sera did not cause direct or complement-mediated cytotoxic effects on normal mononuclear cells nor did they suppress PHA-induced interferon production, nor proliferation of T lymphoblasts or lymphocyte lines. The suppressive effect was not mediated by interferon, cortisol, immunoglobulin G or M, or immune complexes. The activity was stable at pH 3, pH 10, and 60 degrees C; inactivated at 100 degrees C; and not ether extractable. Because IL-2 plays a central role in the development of many immune responses, the serum factor(s) that inhibits IL-2 production could contribute significantly to the immunodeficiency of AIDS.

    PubMed

    2001-01-01

    Post-transplant lymphoproliferative disorders (PTLDs) comprise a histologic spectrum, ranging from hyperplastic-appearing lesions to frank non-Hodgkin's lymphoma or multiple myeloma histology. Multiple clones may coexist, each representing a discrete lymphomagenic event, a situation that is unique to immunodeficiency states. The incidence varies from 1% in renal recipients to 5% in heart recipients, but can be markedly increased by the use of anti-T-cell therapies or by T-cell depletion in bone marrow transplantation. PTLD continues to arise, even many years after transplantation, and late T-cell lymphomas have recently been recognized. Pretransplant Epstein-Barr virus (EBV) seronegativity increases risk to as high as 30%-50%. PTLD has a highly variable clinical picture; certain patterns are, however, seen. Reversibility of PTLD with reduction in immunosuppressives has long been recognized. Predicting reversibility has been difficult. The presence or absence of bcl-6 mutations has recently been identified as being of predictive value. Surgical resection can be curative. Cytotoxics, although problematic, can also be curative. Long-term remission has been achieved with anti CD21 and CD24 antibodies; efficacy has been reported for interferon alfa and for rituximab. In vitro expanded EBV-specific T cells have been effective as treatment and as prophylaxis in the setting of bone marrow transplantation. EBV viral load measured in blood appears to associate with the emergence of PTLD and may facilitate prophylactic studies. PTLD is a model of immunodeficiency-related EBV lymphomagenesis. Pathogenetic, therapeutic, and prophylactic insights gained from the study of PTLD are likely to be applicable to the acquired immunodeficiency syndrome setting.

    A case of primary Pneumocystis carinii infection involving the left middle ear of a patient with acquired immunodeficiency syndrome is described, and the literature on the otic and ophthalmic pneumocystosis is reviewed. Otic pneumocystosis typically presents as a unilateral polypoid mass, and it is clinically manifested as otalgia, hearing loss, or, sometimes, otorrhea without evidence of current respiratory disease or previous Pneumocystis pneumonia. In contrast, choroidal pneumocystosis usually occurs in a patient with acquired immunodeficiency syndrome with at least one previous episode of Pneumocystis pneumonia and aerosolized pentamidine treatment, it is usually asymptomatic and bilateral, and it may be discovered only because of other concurrent human immunodeficiency virus-related ophthalmic disease. The diagnosis is made clinically, and intravenous antiparasite treatment is successful.

    The aim of the present study was to characterize the phonological awareness abilities of a child with Acquired Immunodeficiency Syndrome (AIDS) before and after speech-language therapy. The participant was a 6-year-old girl, first-grade Elementary School student, with AIDS acquired by vertical transmission. The child's phonological awareness abilities were evaluated using the Instrument of Sequential Evaluation of Phonological Awareness (CONFIAS). After this first evaluation, a closed therapeutic program (15 sessions) for phonological awareness was developed, consisting of activities for syllabic and phonemic levels. The CONFIAS was reapplied in the last session in order to investigate therapy effectiveness. In the pre-therapy assessment, the child scored 18 points in syllable tasks and 1 point in phoneme tasks, with a total score of 19 points. In the post-therapy assessment, the child scored 26 points in syllable tasks and 11 points in phoneme tasks, with a total score of 37 points. This study allowed us to characterize the performance of a child with AIDS in tasks of phonological awareness and the effectiveness of the therapeutic program. The score obtained before therapy was much lower than expected for the child's age, and presented significant improvement after speech-language therapy. Thus, professionals working with this population must be aware of therapeutic programs that approach phonological processing abilities in addition to other aspects.

    2013-04-01

    Human herpes viruses cause significant morbidity in patients with the acquired immunodeficiency syndrome. Even after the introduction of highly active anti-retroviral therapy (HAART), herpes viruses remain the leading causes of blindness in AIDS patients. Cytomegalovirus (CMV) retinitis and the closely-related immune reconstitution uveitis syndrome are the most common causes of blindness, but progressive outer retinal necrosis and acute retinal necrosis due to varicella zoster and herpes simplex are also important causes of vision loss. Successful treatment of these conditions requires an aggressive approach with multi-drug intravenous therapy or repeated intravitreal antiviral injections. Since the rate of retinal detachment is alarmingly high despite successful antiviral therapy, internists and ophthalmologists must work closely together to recognize and treat complications as they arise. Fortunately, Epstein-Barr virus is a rare cause of retinal infection and human herpes virus (HHV)-6, HHV-7, and HHV-8 do not appear to be primary pathogens. However, increasing evidence suggests that HHV-6 and HHV-7 play important roles in modulating the immune system and potentiating infection by CMV.

    The opportunistic infections, malignancies, and causes of death related to acquired immunodeficiency syndrome (AIDS) are changing, perhaps as a result of improved treatment, prophylaxis, and education. With its high percentage of persons who acquired the human immunodeficiency virus from intravenous drug (IVD) use, the population of patients with AIDS in the Bronx is potentially unique. All of the 257 consecutive adult human immunodeficiency virus and/or AIDS cases from two Bronx teaching hospitals from 1982 through 1995 were collected. The reports were reviewed for patient demographics, opportunistic infections, malignancies, and causes of death. One hundred thirteen cases from 1982 through 1988 were compared with 144 cases from 1989 through 1995, separated by the institution of antiretroviral therapy and Pneumocystis carinii (PCP) prophylaxis in the latter period. Male homosexuality as a risk factor significantly decreased from 24.8% of the cases in our study from the 1982/88 period to 12.5% during the 1989/95 period (P = 0.014), but IVD use cases showed no change. Cases of AIDS in heterosexual patients increased from 23.9 to 36.1% (P = 0.041) but did not achieve statistical significance unless the unknown risk category (a population shown to be infected predominantly through heterosexual transmission) was included. The prevalence of PCP at autopsy as an opportunistic infection decreased from 37.2 to 25% (P = 0.04), and its prevalence as a cause of death decreased from 31.9 to 13.9% (P = 0.007). This decrease was seen in the homosexual and heterosexual populations but not in the population of IVD users. The homosexual population, as opposed to the population of IVD users, may have taken greater advantage of PCP treatment and prevention. As a result, bronchopneumonia, not PCP, is now the leading cause of death among the patients with AIDS in this study. These findings have important implications for therapy and prophylaxis to control the spread of AIDS and its

    Since the human immunodeficiency virus was identified as etiological agent of the acquired immunodeficiency syndrome, great advances have been accomplished in the therapeutic field leading to reduced morbidity and mortality among infected patients. However, the high mutation rate of the viral genome generates strains resistant to multiple drugs, pointing to the importance of finding new therapeutic targets. Among the HIV structural genes, the POL gene codes for three essential enzymes: reverse transcriptase, protease, and integrase; nineteen of the twenty drugs currently approved by the Food and Drug Administration to treat this viral infection, inhibit the reverse transcriptase and the protease. Although intense research has been carried out in this area during the last 10 years, HIV integrase inhibitors are not yet approved for clinical use; however the fact that presence of this enzyme is a sine qua non for a productive HIV life cycle joined to its unique properties makes it a promissory target for anti-HIV therapy. Many compounds have been claimed to inhibit integrase in vitro; however, few of them have proven to have antiviral activity and low cytotoxicity in cell systems. Diketoacid derivatives are the most promising integrase inhibitors so far reported. Initially discovered independently by Shionogi & Co. and the Merck Research Laboratories, these compounds are highly specific for the integrase with potent antiviral activity in vitro and in vivo, and low cytotoxicity in cell cultures. Some of these compounds have recently entered clinical trials. Due to the high relevance of integrase inhibitors, and specifically of diketoacid derivatives, we review the latest findings and patents in this important field of research.

    Previous research has demonstrated isolated effects of host genetic factors on the progression of human immunodeficiency virus type 1 (HIV-1) infection. In this paper, the authors present a novel use of multivariable methods for estimating the prevented fraction of acquired immunodeficiency syndrome (AIDS) cases attributable to six restriction genes after accounting for their epidemiologic interactions. The methods presented will never yield a prevented fraction above 1. The study population consisted of a well-characterized cohort of 525 US men with HIV-1 seroconversion documented during follow-up (1984-1996). On the basis of a regression tree approach using a Cox proportional hazards model for times to clinical AIDS, the combinations of genes associated with the greatest protection, relative to the lack of a protective genotype, consisted of: 1) C-C chemokine receptor 5 (CCR5)-Delta 32 and C-C chemokine receptor 2 (CCR2)-64I (relative hazard = 0.44); 2) interleukin 10 (IL10)-+/+ in combination with CCR5-Delta 32 or CCR2-64I (relative hazard = 0.45); and 3) IL10-+/+ in combination with stromal-derived factor (SDF1)-3 'A and CCR5 promoter P1/approximately P1 (relative hazard = 0.37). Overall, 30% of potential AIDS cases were prevented by the observed combinations of restriction genes (95% confidence interval: 7, 47). However, the combined effect was confined to the first 4 years following HIV-1 seroconversion. Additional research is needed to identify AIDS restriction genes with stronger and long-lasting protection to better characterize the genetic epidemiology of HIV-1.

    The time of re-evaluation of the role of human immunodeficiency viruses in the pathogenesis of acquired immune deficiency syndrome has now come, now that methods are available for the direct detection of human immunodeficiency viruses and for the detection of cellular anti-human immunodeficiency virus immune reactions. It has been shown that human immunodeficiency virus infections are common among anti-human immunodeficiency virus antibody negative high-risk individuals. The disease is brought under control by cellular immune reactions and the anti-human immunodeficiency virus antibody test remains negative. Apart from proof that infection with human immunodeficiency viruses has occurred, a positive result in an anti-human immunodeficiency virus-antibody test is also an indication of an independent immunosuppression state. According to the definition of the Centers of Disease Control classical acquired immune deficiency syndrome is the consequence of infection with human immunodeficiency virus in association with continuous excessive stress, such as observed in the known risk groups. At the center of the pathogenetic process is hypercortisolism-determined damage of T lymphocytes, in which insufficiency of thymus is prominent. For this reason, in our view, there are indications for shifting efforts from the prophylaxis of infection with human immunodeficiency viruses to the prophylaxis of acquired immune deficiency syndrome by reducing stress factors.

    Toxoplasmosis is a common opportunistic pathogen in patients with acquired immunodeficiency syndrome (AIDS). It usually presents with ocular, central nervous system, or pulmonary disease. Gastric toxoplasmosis is uncommon in AIDS patients, especially in the absence of central nervous system manifestations. In the few reported cases, patients have presented with abdominal pain and other digestive complaints that usually are attributed to the more common gastrointestinal manifestations of human immunodeficiency virus infection. We describe a 49-year-old man with AIDS who presented with abdominal pain, diarrhea, dry cough, and systemic symptoms and was diagnosed with toxoplasmosis by a gastric biopsy.

    Gastrointestinal symptoms attributable to Toxoplasma gondii infection are distinctly unusual, and antemortem diagnosis of gastrointestinal involvement is rarely documented, particularly in the absence of cerebral manifestations or disseminated disease. This case report describes a rare example of T. gondii infection of the stomach diagnosed antemortem in a 22-year-old Haitian woman with acquired immunodeficiency syndrome (AIDS) who presented with fever and abdominal pain. An abdominal computerized tomographic scan showed thickened gastric walls. Endoscopy showed diffusely thickened gastric folds and a fundic ulcer along the greater curvature. Light and electron-microscopic examination of gastric mucosal biopsy specimens showed active Toxoplasma infection with necrosis and intracellular trophozoites within the gastric epithelium, smooth muscle cells, macrophages, and endothelial cells. Both true cysts and pseudocysts were seen. Disseminated disease was documented by the growth of T. gondii in a tissue culture from a venous blood sample. It is concluded that some patients with AIDS, particularly those from areas endemic for Toxoplasma infection, can manifest disseminated disease in unusual locations such as the gastrointestinal tract. Documentation of active T. gondii infection based on tissue cultures of venous blood or on biopsy specimens of symptomatic extracerebral sites can lead to a rapid diagnosis of toxoplasmosis, a treatable disease.

    To characterize the postmortem pulmonary disease and analyze the effectiveness of antemortem diagnosis, we examined the clinical records and autopsy material from 54 patients who died of the acquired immunodeficiency syndrome. At autopsy, all patients had pulmonary disease. One or more specific diagnoses were made in 53, including opportunistic infection, nonopportunistic infection, and Kaposi's sarcoma. Multiple postmortem pulmonary diagnoses were established in 37. Respiratory failure was the most common cause of death. Of the 97 pulmonary disorders discovered at autopsy, only 31 were diagnosed before death. The frequency with which infections were diagnosed during life varied according to the organism, and was significantly higher for Pneumocystis carinii than for cytomegalovirus or bacterial agents. Pulmonary Kaposi's sarcoma was diagnosed in only 7% of patients with autopsy documentation. The yield of diagnostic procedures also varied according to the disease present. Sputum culture was relatively effective in detecting Cryptococcus neoformans and Mycobacterium avium-intracellulare, fiber-optic bronchoscopy was extremely useful for diagnosing P Carinii, and one or more diagnoses were provided in 4 of 7 patients who underwent thoracotomy, but significant disease including cytomegalovirus infection and pulmonary Kaposi's sarcoma was frequently missed. Although the spectrum of lung disease found at autopsy is similar to that observed during life, the frequency of some pathologic processes including cytomegalovirus infection and Kaposi's sarcoma may be underrepresented in antemortem series.

    Nurses who work with seriously ill and dying patients are engaged in helping them live fully until they die. Most theories of death and dying deal with conscious activities only. Yet many people find relief form the fear and loneliness of life-threatening illness if given the opportunity to express their totality, meaning their unconscious as well as conscious processes. Working with the mind may not be enough. Attending to the unconscious through dream work can allow inner healing to occur, which can support that person as he or she moves into the unknown. The article describes the AIDS Dreamwork Project, the goals of which are to understand patients better and to help them better understand themselves, to help them live and die more consciously, and to discern patterns in their dreams that may be unique to people with acquired immunodeficiency syndrome. Six themes have been identified in the dreams collected so far: wake-up dreams; reassurance dreams; dreams of opposition, separation, or coming together; transition dreams; transformation dreams; and spiritual or archetypal dreams.

    Tuberculous osteomyelitis is rare and usually involves the vertebrae but is seldom found in the foot. The uncommon site and ability to mimic other disorders clinically and radiographically leads to diagnostic and therapeutic delays. We report a case of a 40-year-old man who initially presented to his podiatrist with intermittent pain and swelling of his right ankle and foot that lasted for a year. He also started to exhibit significant weight loss and unexplained fevers and was subsequently hospitalized for cellulitis of his right foot. On further workup, patient was found to have miliary tuberculosis (TB) and acquired immunodeficiency syndrome (AIDS). Patient was treated with anti-TB therapy for 9 months and highly active anti-retroviral therapy. Our patient presented with ongoing chronic right foot and ankle pain that was proven to be secondary to TB osteomyelitis of cuneiform bones of the right ankle in the setting of AIDS. The patient's clinical presentation was unusual due to symptom duration and lack of systemic characteristics. Like our case, reported incidence of osteomyelitis of bone/joint in extrapulmonary TB is estimated to be 10%, and out of all bones/joint TB cases, only 1% are found to be in the foot. PMID:27802849

    Ocular complications are known to occur as a result of human immunodeficiency virus (HIV) disease. They can be severe leading to ocular morbidity and visual handicap. Cytomegalovirus (CMV) retinitis is the commonest ocular opportunistic infection seen in acquired immune deficiency syndrome (AIDS). Though posterior segment lesions can be more vision-threatening, there are varied anterior segment manifestations which can also lead to ocular morbidity and more so can affect the quality of life of a HIV-positive person. Effective antiretroviral therapy and improved prophylaxis and treatment of opportunistic infections have led to an increase in the survival of an individual afflicted with AIDS. This in turn has led to an increase in the prevalence of anterior segment and adnexal disorders. Common lesions include relatively benign conditions such as blepharitis and dry eye, to infections such as herpes zoster ophthalmicus and molluscum contagiosum and malignancies such as squamous cell carcinoma and Kaposi′s sarcoma. With the advent of highly active antiretroviral therapy, a new phenomenon known as immune recovery uveitis which presents with increased inflammation, has been noted to be on the rise. Several drugs used in the management of AIDS such as nevirapine or indinavir can themselves lead to severe inflammation in the anterior segment and adnexa of the eye. This article is a comprehensive update of the important anterior segment and adnexal manifestations in HIV-positive patients with special reference to their prevalence in the Indian population.

    In addition to immunologic derangement, hematological abnormalities have been reported in the majority of patients with acquired immunodeficiency syndrome (AIDS). In this study 15 patients with AIDS or AIDS-related complex (ARC) were evaluated for the in vitro growth of hemopoietic progenitor cells. In all patients a significant reduction of growth (mean +/- SEM) of colony-forming unit-granulocyte, erythrocyte, macrophage, (megakaryocyte) (CFU-GEM) (1.2 +/- 0.3), burst-forming unit-erythroid (BFU-E) (17 +/- 10), CFU-megakaryocyte (CFU-Mk) (1.7 +/- 0.6), and CFU-granulocyte-macrophage (CFU-GM) (35 +/- 10) was observed in comparison with normal controls. Depletion of T cells from the bone marrow before culture led to a significant increase in colony growth, which indicated an imbalance of the normally modulating T cell subsets. This increase was reversed by readdition of autologous T cells causing a decrease in colony growth to a degree, dependent on the T4 to T8 ratio. A decreased number of hemopoietic progenitor cells and/or a defective modulation of progenitor cell growth, normally carried out by T lymphocyte subsets, might be the cause of the hematological abnormalities in AIDS patients.

    Entry of acquired immune deficiency syndrome virus into the host immune cell involves the participation of various components of host and viral cell unit. These components may be categorized as attachment of the viral surface envelope protein subunit, gp120, to the CD4(+) receptor and chemokine coreceptors, CCR5 and CXCR4, present on T cell surface. The viral fusion protein, gp41, the second cleaved subunit of Env undergoes reconfiguration and the membrane fusion reaction itself. Since the CD4(+) T cell population is actively involved; the ultimate outcome of human immunodeficiency virus infection is total collapse of the host immune system. Mathematical modeling of the stages in viral membrane protein-host cell receptor-coreceptor interaction and the effect of antibody vaccine on the viral entry into the susceptible host cell has been carried out using as impulsive differential equations. We have studied the effect of antibody vaccination and determined analytically the threshold value of drug dosage and dosing interval for optimum levels of infection. We have also investigated the effect of perfect adherence of drug dose on the immune cell count in extreme cases and observed that systematic drug dosage of the immune cells leads to longer and improved lives.

    Disseminated mycobacterial infections are commonly seen in acquired immunodeficiency syndrome (AIDS) patients, and laboratory culture is the best method for diagnosing these infections. In addition to conventional agar media, we used BACTEC 12A (Johnston Laboratories, Inc., Towson, Md.) broth medium for culture. More isolates of Mycobacterium avium complex and Mycobacterium tuberculosis were recovered from 12A broth than from Lowenstein-Jensen or Middlebrook 7H11 agar. Also, the average detection time of these mycobacteria was the earliest with 12A broth. Stool examination has been helpful in diagnosing mycobacterial disease in AIDS patients, and in this study both acid-fast stain and culture of fecal material was necessary for efficient detection of mycobacteria. Another sensitive and practical method for detecting mycobacterial infections in patients with AIDS is the Isolator lysis-centrifugation system (Du Pont Co., Wilmington, Del.) which offers the advantage of quantitating the degree of mycobacteremia. Laboratories should be alerted to the possibility of mixed mycobacterial infection in patients with AIDS, and positive cultures should be repeatedly examined to detect coinfection with a slower-growing mycobacterium such as M. tuberculosis as well as M. avium complex.

    A methodology based on micellar liquid chromatography to monitor five antiretroviral drugs (lamivudine, stavudine, tenofovir, zidovudine and efavirenz) was proposed. Antiretrovirals were studied in sets of three, corresponding to each highly active antiretroviral therapy (HAART) regime, prescribed to acquired immunodeficiency syndrome (AIDS)-infected patients. Four aqueous micellar mobile phases buffered at pH 7 were optimized to separate these compounds, using sodium dodecyl sulfate as the tensioactive, and 1-propanol or 1-pentanol as the organic modifier. The composition of each mobile phase was optimized for each antiretroviral. The common separation conditions were: C18 apolar column (125 × 4.6 mm, 5 μm particle size), UV detection set at 214 nm, and mobile phase running at 1 mL min(-1) without controlling the temperature. The finally suggested method was validated for five analysed antiretroviral drugs following the US Food and Drug Administration guidelines in terms of: linearity between 0.5 and 50 ppm (r(2) > 0.9995), sensitivity (LOD lower than 0.25 ppm), intra- and inter-day precision (<7.1 and <5.2%, respectively) and accuracy (recovery 88.5-105.3% and 93.5-101.3%, respectively), as well as robustness (<6.5%). The proposed method was used to monitor the level of antiretrovirals in the serum of AIDS patients. The suggested methodology was found to be useful in the routine analysis of antiretrovirals in serum samples.

    A 45-year-old man, a case of acquired immunodeficiency syndrome, received a highly active antiretroviral therapy at the outpatient service for 4 years without regular follow-up. He experienced progressively blurred vision for 6 months and a cutaneous zoster on his back 3 months ago. He was diagnosed with progressive outer retinal necrosis by polymerase chain reaction-restriction fragment length polymorphism using an aqueous humor sample, which revealed an existence of varicella zoster virus. He was given a combination of systemic, intravitreal antiviral and a highly active antiretroviral therapy. Occlusive vasculitis, an unusual finding for progressive outer retinal necrosis, developed in both eyes 1 week after the secondary intravitreal injection. Unfortunately, his vision deteriorated to no light perception in both eyes within 2 weeks. Progressive outer retinal necrosis is characterized clinically as showing minimal or no inflammation in the aqueous and vitreous humors, absence of retinal vasculitis, and patches of yellowish spots located deep in the retina. Physicians should pay attention to this rare case of progressive outer retinal necrosis associated occlusive vasculitis with very poor prognosis in spite of aggressive treatment.

    The aims of this study were to compare outcomes of appendectomy between acquired immunodeficiency syndrome (AIDS) and nonAIDS patients and laparoscopic appendectomy (LA) versus open appendectomy (OA) in AIDS patients. Using the Nationwide Inpatient Sample database, from 2006 to 2008, clinical data of patients with AIDS who underwent LA and OA were evaluated. A total of 800 patients with AIDS underwent appendectomy during these years. Patients with AIDS had a significantly higher postoperative complication rate (22.56% vs 10.36%), longer length of stay [(LOS) 4.9 vs 2.9 days], and higher mortality (0.61% vs 0.16%) compared with non-AIDS patients. In nonperforated cases in patients with AIDS, LA was associated with a significantly lower complication rate (11.25% vs 21.61%), lower mortality (0.0% vs 2.78%), and shorter mean LOS (3.22 days vs 4.82 days) compared with OA. In perforated cases in patients with AIDS, LA had a significantly lower complication rate (27.52% vs 57.50%), and shorter mean LOS (5.92 days vs 9.67 days) compared with OA. No mortality was reported in either group. In patients with AIDS, LA has a lower morbidity, lower mortality, and shorter LOS compared with OA. Laparoscopic appendectomy should be considered as a preferred operative option for acute appendicitis in patients with AIDS.

    Acquired Immunodeficiency Syndrome (Aids) was initially related to HIV-associated wasting syndrome, and its metabolic disturbances to altered body composition. After Highly Active Antiretroviral Therapy (HAART) was started, malnutrition has declined and HIV-associated lipodystrophy syndrome has emerged as an important metabolic disorder. Aids is also characterized by hormonal disturbances, principally in growth hormone/insulin-like growth factor 1 (GH/IGF-1) axis. The use of recombinant human GH (hrGH) was formerly indicated to treat wasting syndrome, in order to increase lean body mass. Even though the use of hrGH in lipodystrophy syndrome has been considered, the decrease in insulin sensitivity is a limitation for its use, which has not been officially approved yet. Diversity in therapeutic regimen is another limitation to its use in Aids patients. The present study has reviewed the main HIV-related endocrine-metabolic disorders as well as the use of hrGH in such conditions.

    whose viral burden was predominantly at 1 x 10(6) copies/ml or greater developed encephalitis. To further investigate the relationship between CD163(+)/CD16(+) MPhis/microglia in the CNS and altered homeostasis in the periphery, the authors performed flow-cytometric analyses of peripheral blood mononuclear cells (PBMCs) from SIV-infected rhesus macaques. The results demonstrate an increase in the percent frequency of CD163(+)/CD16(+) monocytes in animals with detectable virus that correlated significantly with increased viral burden and CD4(+) T-cell decline. These results suggest the importance of this monocyte subset in HIV/SIV CNS disease, and also in the immune pathogenesis of lentiviral infection. The authors further discuss the potential role of CD163(+)/CD16(+) monocyte/MPhi subset expansion, altered myeloid homeostasis, and potential consequences for immune polarization and suppression. The results and discussion here suggest new avenues for the development of acquired immunodeficiency syndrome (AIDS) therapeutics and vaccine design.

    Several sub-Saharan militaries have large percentages of troops with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome. With the arrival of avian influenza in Africa, the potential exists that some of those soldiers might also become infected with H5N1, the virus responsible for the disease. Two possible scenarios have been postulated regarding how such a coinfection of HIV and H5N1 might present. (1) Soldiers already weakened by HIV/acquired immunodeficiency syndrome rapidly succumb to H5N1. The cause of death is a "cytokine storm," essentially a runaway inflammatory response. (2) The weakened immune system prevents the cytokine storm from occurring; however, H5N1 is still present, replicating, and being shed, leading to the infection of others. A cytokine storm is particularly dangerous for individuals of military age, as evidenced by the large number of soldiers who died during the 1918 influenza epidemic. If large numbers of sub-Saharan soldiers suffer a similar fate from avian influenza, then military and political instability could develop.

    Human immunodeficiency virus (HIV) infection associated aneurysmal vasculopathy is a rare complication of HIV infection affecting the pediatric and adult population. We present a case of a 7-year-old male child known to have a congenitally acquired HIV infection presenting with a ruptured left distal internal carotid artery fusiform aneurysm that was diagnosed on MRI scans 6 months prior to his presentation. He underwent craniotomy and successful aneurysm reconstruction. He had uncomplicated postoperative course and experienced a good recovery. This case is among the few reported pediatric cases of HIV-associated cerebral arteriopathy to undergo surgery. We also reviewed the relevant literature of this rare condition. PMID:26166600

    Temporal trends in the incidence of opportunistic diseases (ODs) related to acquired immunodeficiency syndrome (AIDS) were studied during 1989-1997 in 1115 outpatients infected with human immunodeficiency virus (331 of whom had AIDS) in a hospital in Madrid, Spain. We analyzed the effect of adherence to antiretroviral therapy and Pneumocystis carinii pneumonia (PCP) prophylaxis on the incidence of OD. Diseases that showed a significant decreasing trend were esophageal candidiasis, pulmonary and extrapulmonary tuberculosis, and cerebral toxoplasmosis. Patients who adhered to antiretroviral therapy had a smaller risk of OD. Patients who adhered to PCP prophylaxis had a reduced risk of cerebral toxoplasmosis and PCP. A reduction in the incidence of AIDS-related ODs was observed, mainly in patients who underwent prophylaxis. Adherence to antiretroviral treatment and PCP prophylaxis was associated with a reduction in the risk of disease.

    Thirty-nine percent of Argentineans living with acquired immunodeficiency syndrome were infected with human immunodeficiency virus through the injection of drugs. However, it was not until the 1990s that harm reduction programs were created. Research and outreach projects have been developed to identify and interact with the hidden injection drug user (IDU) population. Implementation of rapid assessment and response methodology contributed to the founding of Argentina's first syringe exchange program. Community-based outreach is the appropriate method for working with the impoverished population of Buenos Aires. Seroprevalence studies and focused prevention campaigns targeting IDUs and their sex partners and children have been developed. Collaborations between government and nongovernmental organizations in various cities supported the distribution of prevention and harm reduction messages to 900 IDUs within a 3-month period. Ongoing research, community-based interventions, and collaborative work among different organizations allow for more frequent and more consistent contact with the IDU population of Argentina.

The 2013 Texas Conference on Health Disparities brought together experts, in research, patient care and community outreach, on the "Intersection of Smoking, Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and Cancer". Smoking, HIV/AIDS and cancer are three individual areas of public health concern, each with its own set of disparities and risk factors based on race, ethnicity, gender, geography and socio-economic status. Disparities among patient populations, in which these issues are found to be comorbid, provide valuable information on goals for patient care. The conference consisted of three sessions addressing "Comorbidities and Treatment", "Public Health Perspectives", and "Best Practices". This article summarizes the basic science, clinical correlates and public health data presented by the speakers.

    Primary immunodeficiency diseases (PID) are associated with various autoimmune complications and several manifestations of autoimmunity can be seen in the disorders of T cells, B cells, phagocytes, and complement components. Acquired hemophilia is a rare entity in childhood. Although autoantibodies may develop in various forms of PID, Factor VIII (FVIII) inhibitors have not been described before. Herein, we present a case of acquired hemophilia resulting from FVIII inhibitors who had underlying undefined PID features suggestive of autosomal recessive hyper IgE syndrome. Our patient responded to corticosteroid treatment rather well and quickly, with an increased FVIII level and decreased FVIII inhibitors. However, FVIII inhibitor reappeared 7 months later, and disappeared spontaneously 4 months ago. Long-term and close follow-up is needed to observe the long-term prognosis in this child.

    Thirty-three homosexual patients with thrombocytopenia (mean [+/- SE] platelet count, 50 000 +/- 7000/mm3; range, 7 to 135 000/mm3) have been followed for a mean period of 20 +/- 2 months. Six patients have developed the acquired immunodeficiency syndrome 1 to 37 months after the diagnosis of thrombocytopenia. Six patients spontaneously reverted to normal platelet counts 5 to 27 months (median, 10 months) after the diagnosis of thrombocytopenia, in the absence of splenectomy and while not receiving corticosteroids. Sixteen of seventeen patients had a moderate to excellent response while on corticosteroid treatment. Ten of ten patients had an excellent response to splenectomy which has persisted. Fifteen patients did not require treatment for their thrombocytopenia. Thirteen of fourteen patients had antibody against the retrovirus associated with the acquired immunodeficiency syndrome, as did 4 of 12 homosexual controls without thrombocytopenia. Thrombocytopenia in homosexuals is part of the complex related to the acquired immunodeficiency syndrome.

    An effective vaccine against acquired immune deficiency syndrome is still unavailable after dozens of years of striving. The glycoprotein gp41 of human immunodeficiency virus is a good candidate as potential immunogen because of its conservation and relatively low glycosylation. As a reference of human immunodeficiency virus gp41, gp45 from equine infectious anemia virus (EIAV) could be used for comparison because both wild-type and vaccine strain of EIAV have been extensively studied. From structural studies of these proteins, the conformational changes during viral invasion could be unveiled, and a more effective acquired immune deficiency syndrome vaccine immunogen might be designed based on this information.

    The clinical data, histologic findings, and computed tomographic (CT) abnormalities in eight adult Haitians with toxoplasma encephalitis were analyzed retrospectively. Diagnosis was established by identification of Toxoplasma gondii on autopsy in five and brain biopsy in three specimens and subsequently confirmed by the immunoperoxidase method. All these patiens, six of whom had been in the United States for 24 months or less, had severe idiopathic immunodeficiency syndrome. All were lymphopenic and six were on treatment for tuberculosis when the toxoplasma encephalitis developed. All patients were studied with CT when they developed an altered mental status and fever associated with seizures and/or focal neurologic deficits. Scans before treatment showed multiple intraparenchymal lesions in seven and a single lesion in the thalamus in one. Ring and/or nodular enhancement of the lesions was found in six and hypodense areas in two. Progressions of abnormalities occurred on serial studies. These CT findings that were best shown on axial and coronal thin-section double-dose contrast studies were useful but not diagnostically pathognomonic. In patients with similar clinical presentation CT is recommended to identify focal areas of involvement and to guide brain biopsy or excision so that prompt medical thereapy of this often lethal infection can be instituted.

    Depression can be a chronic and impairing illness in people with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome. Large randomized studies of newer selective serotonin reuptake inhibitors such as escitalopram in the treatment of depression in HIV, examining comparative treatment efficacy and safety, have yet to be done in HIV-positive patients. This was a fixed-dose, placebo-controlled, randomized, double-blind study to investigate the efficacy of escitalopram in HIV-seropositive subjects with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, major depressive disorder. One hundred two participants were randomly assigned to either 10 mg of escitalopram or placebo for 6 weeks. An analysis of covariance of the completers found that there was no advantage for escitalopram over placebo on the Montgomery-Asberg Depression Rating Scale (p = 0.93). Sixty-two percent responded to escitalopram and 59% responded to placebo on the Clinical Global Impression Scale. Given the relatively high placebo response, future trials in this area need to be selective in participant recruitment and to be adequately powered.

    Stigma has been implicated in poor outcomes of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) care. Reducing stigma is important for HIV prevention and long-term treatment success. Although stigma reduction interventions are conducted in Mozambique, little is known about the current nature of stigma and the efficacy and effectiveness of stigma reduction initiatives. We describe action research to generate consensus on critical characteristics of HIV stigma and anti-stigma interventions in Zambézia Province, Mozambique. Qualitative data gathering methods, including indepth key-informant interviews, community interviews and consensus group sessions, were utilized. Delphi methods and the strategic options development analysis technique were used to synthesize qualitative data. Key findings are that stigma enacted by the general public might be declining in tandem with the HIV/AIDS epidemic in Mozambique, but there is likely excessive residual fear of HIV disease and community attitudes that sustain high levels of perceived stigma. HIV-positive women accessing maternal and child health services appear to shoulder a disproportionate burden of stigma. Unintentional biases among healthcare providers are currently the critical frontier of stigmatization, but there are few interventions designed to address them. Culturally sensitive psychotherapies are needed to address psychological distress associated with internalized stigma and these interventions should complement current supports for voluntary counseling and testing. While advantageous for defining stakeholder priorities for stigma reduction efforts, confirmatory quantitative studies of these consensus positions are needed before the launch of specific interventions.

    We briefly review findings from Brazilian settings where the human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) epidemic among injection drug users (IDUs) seems to be decreasing, highlighting recent findings from Rio de Janeiro and discussing methodological alternatives. Former analyses using serologic testing algorithm for recent HIV seroconversion have shown that HIV incidence has been low in IDUs recruited by two different surveys carried out in Rio, where low injection frequencies and infection rates have been found among new injectors. The proportion of AIDS cases among IDUs in Rio has been fairly modest, compared to São Paulo and especially to the southernmost states. Notwithstanding, the interpretation of findings from serial surveys constitutes a challenge, magnified in the assessment of HIV spread among IDUs due to the dynamic nature of the drug scenes and limitations of sampling strategies targeting hard-to-reach populations. Assessment of epidemic trends may profit from the triangulation of data, but cannot avert biases associated with sampling errors. Efforts should be made to triangulate data from different sources, besides exploring specific studies from different perspectives. In an attempt to further assess the observed trends, we carried out original analyses using data from Brazilian AIDS databank.

    We report a case of non-acquired immunodeficiency syndrome-defining lung adenocarcinoma in a multidrug-resistant human immunodeficiency virus (HIV)-positive patient. The patient was a 47-year-old Japanese woman who received salvage combination anti-retroviral therapy with darunavir plus ritonavir plus raltegravir plus tenofovir/emtricitabine in May 2009. She was diagnosed with lung adenocarcinoma (T3N3M1, stage IV) in November 2010 and was not found to possess any activating mutations in the epidermal growth factor receptor gene. Therefore, 6 courses of carboplatin plus pemetrexed and 3 courses of gemcitabine followed by erlotinib were administrated, and therapy was changed to home medical care. The only drug-related adverse event was grade 1 neutropenia, and drug interaction between the simultaneously administered anti-retroviral and chemotherapeutic agents was not confirmed. The patient battled lung adenocarcinoma for 1 year after the diagnosis and died of cancer progression in October 2011. Her performance status was stable and the CD4 (+) lymphocyte count and HIV load were well controlled throughout the course of treatment. In conclusion, the agents used for this patient show high tolerability and can be used as an effective treatment strategy for lung cancer occurring in HIV-positive patients.

    Stigma has been implicated in poor outcomes of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) care. Reducing stigma is important for HIV prevention and long-term treatment success. Although stigma reduction interventions are conducted in Mozambique, little is known about the current nature of stigma and the efficacy and effectiveness of stigma reduction initiatives. We describe action research to generate consensus on critical characteristics of HIV stigma and anti-stigma interventions in Zambézia Province, Mozambique. Qualitative data gathering methods, including in-depth key-informant interviews, community interviews and consensus group sessions, were utilized. Delphi methods and the strategic options development analysis technique were used to synthesize qualitative data. Key findings are that stigma enacted by the general public might be declining in tandem with the HIV/AIDS epidemic in Mozambique, but there is likely excessive residual fear of HIV disease and community attitudes that sustain high levels of perceived stigma. HIV-positive women accessing maternal and child health services appear to shoulder a disproportionate burden of stigma. Unintentional biases among healthcare providers are currently the critical frontier of stigmatization, but there are few interventions designed to address them. Culturally sensitive psychotherapies are needed to address psychological distress associated with internalized stigma and these interventions should complement current supports for voluntary counseling and testing. While advantageous for defining stakeholder priorities for stigma reduction efforts, confirmatory quantitative studies of these consensus positions are needed before the launch of specific interventions.

    Cytokine dysregulation and decontrol of Epstein-Barr virus (EBV) latency by human immunodeficiency virus (HIV) infection are potential mechanisms for acquired immunodeficiency syndrome (AIDS)-related non-Hodgkin lymphoma (NHL). We therefore assessed circulating blood levels in pre-diagnosis plasma or serum from 63 AIDS-related NHL cases 0.1 – 2.0 (median 1.0) years pre-NHL and 181 controls matched for CD4+ T-cell count. Cytokines were measured by Millipore 30-plex Luminex assays and cell-free EBV DNA detected by polymerase chain reaction (PCR). Correlations in multiplex cytokine levels were summarized by factor analysis. Individual cytokines and their principal factors were analyzed for associations with NHL by conditional logistic regression. Cases had higher levels for 25 of the 30 cytokines. In analyses of cytokine profiles, cases had significantly higher scores for a principal factor primarily reflecting levels of interleukin (IL)-4, IL-5, IL-13, and granulocyte-macrophage colony stimulating factor (four gene products with coordinated transcription in vitro), as well as IL-1alpha. Epstein-Barr viremia was not significantly associated based on 113 evaluable samples without PCR inhibition. We found increases of T-helper type 2 interleukins and generalized elevations of other inflammatory cytokines and growth factors up to two years before AIDS-NHL. Cytokine-mediated hyperstimulation of B-cell proliferation may play a role in AIDS-related lymphomagenesis. PMID:22022727

    Low incidence of human immunodeficiency virus (HIV) infections and acquired immunodeficiency syndrome (AIDS) has been detected in Croatia so far. Toxoplasmic encephalitis (TE) is the most common opportunistic cerebral infection in AIDS patients and is highly responsive to antiparasitic chemotherapy, if treated at an early stage. We present the case of the brain biopsy confirmed as TE on a 36-year-old female patient who at admission presented with unconsciousness and a right hemiplegia. A MSCT was performed and two hypodense lesions were diagnosed. The patient's family initially denied the presence or history of any medical problem or infection. An MRI showed multiple ring-enhanced mass lesions. An infectologist required a brain biopsy to exclude cerebral lymphoma and multiple metastases. Pathohistological analysis suggested TE. Meanwhile, patient's blood samples were found to be HIV positive. The patient was transferred to University Hospital for Infectious Diseases in Zagreb, where she died 2 days following admission. The patient's family terminally confessed that the patient had been HIV positive for 10 years and had refused any treatment. Family's denial of infection as well as 'hiding information' concerning patient's health from physicians involved in her treatment caused a delay in proper on-time patient treatment. We would like to emphasize that TE must be considered as a differential diagnosis in patients presenting with multiple cerebral lesions, including patients without acknowledged past history of HIV infection. A stigma towards HIV infection and ignorance of the disease still exist and therefore hinders proper treatment.

    We reviewed the histological features of untreated toxoplasmosis in 18 cases with the acquired immunodeficiency syndrome (AIDS), eight of which were surgical biopsies and 10 of which were autopsy specimens. The results were compared according to the clinical status of the patient at the time the diagnosis of toxoplasmosis was made (early-onset v late-onset AIDS) and according to the source of the specimen (surgical biopsy specimen v autopsy specimen). Cerebral toxoplasmosis was the AIDS-defining illness in half of the cases (six surgical biopsy specimens and three autopsy specimens). Inflammation in these cases was moderate in 44% and severe in 56%. Fibrous capsules were found in five cases. Lymphocytes and plasma cells were more prominent than neutrophils. Cerebral toxoplasmosis developed in or was part of the terminal AIDS illness in the remaining nine cases (two surgical biopsy specimens and seven autopsy specimens). In this group inflammation was sparse in 44%, moderate in 55%, and severe in only 11%. Fibrous capsules were usually absent and neutrophils were the predominant cell type. Comparisons between surgical biopsy specimens and autopsy specimens showed moderate to severe inflammation and frequent fibrous encapsulation in all of the former specimens but only in those autopsy specimens in which toxoplasmosis was the initial manifestation of AIDS. Thus, this study demonstrates varied neuropathological patterns of untreated cerebral toxoplasmosis in patients with AIDS and correlates the inflammatory response in the brain with the clinical stage of the patient's human immunodeficiency syndrome (HIV) infection. Inflammation and fibrous encapsulation were common only in patients with early-onset AIDS in whom cerebral toxoplasmosis was the first manifestation of the illness. This study highlights important differences between the histology of this infection at surgical biopsy and at autopsy, and stresses the need to consider toxoplasma as a potential cause of

    Human immunodeficiency virus (HIV) infection is a serious condition associated to severe immune dysfunction and immunodeficiency. Mechanisms involved in HIV-associated immune activation, inflammation and loss of CD4+ T cells have been extensively studied, including those concerning purinergic signaling pathways. Purinergic signaling components are involved in viral entry and replication and disease progression. Research involving the participation of purinergic signaling in HIV infection has been not only important to elucidate disease mechanisms but also to introduce new approaches to therapy. The involvement of purinergic signaling in the pathogenesis of HIV infection and its implications in the control of the HIV infection are reviewed in this paper.

    Objectives: Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) adversely impacts food security in households of people living with HIV/AIDS (PLWHA). Little research has focused on food insecurity among PLWHA in India. The purpose of this study was to identify the prevalence of and factors relating to food security in households of PLWHA in the Siliguri subdivision of Darjeeling, West Bengal, India. Methods: A cross-sectional community-based study was carried out among 173 PLWHA residing in Siliguri and registered at the Anti-retroviral Therapy Centre of North Bengal Medical College & Hospital. Data was collected at the household level with interviews of PLWHA using a food security survey instrument. We analyzed the associations using logistic regression. Results: The prevalence of household food security among the participants was 50.9% (88/173). Five years or more of schooling, higher socioeconomic class and males were found to be significantly associated with a higher likelihood of food security. A later stage of the disease and the presence of other family members with HIV/AIDS were significantly associated with a lower likelihood of food security. The major coping strategies to deal with food insecurity in the acute phase HIV infection included borrowing money (56.1%), followed by spousal support, loans from microfinance institutions, banks, or money lenders, borrowing food, or selling agricultural products. Conclusions: The present study revealed that only about half of households with PLWHA were food secure. Prior interventions relating to periods of food and economic crisis as well as strategies for sustaining food security and economic status are needed in this area. PMID:27499166

    Although discontinuation of suppressive antifungal therapy for acquired immunodeficiency syndrome (AIDS)-associated histoplasmosis is accepted for patients with immunologic recovery, there have been no published studies of this approach in clinical practice, and minimal characterization of individuals who relapse with this disease. We performed a multicenter retrospective cohort study to determine the outcome in AIDS patients following discontinuation of suppressive antifungal therapy for histoplasmosis. Ninety-seven patients were divided into a physician-discontinued suppressive therapy group (PD) (38 patients) and a physician-continued suppressive therapy group (PC) (59 patients). The 2 groups were not statistically different at baseline, but at discontinuation of therapy and at the most recent follow-up there were significant differences in adherence to therapy, human immunodeficiency virus (HIV) RNA, and urinary Histoplasma antigen concentration. There was no relapse or death attributed to histoplasmosis in the PD group compared with 36% relapse (p < 0.0001) and 5% death (p = 0.28) in the PC group. Relapse occurred in 53% of the nonadherent patients but not in the adherent patients (p < 0.0001). Sixty-seven percent of patients with initial central nervous system (CNS) histoplasmosis relapsed compared to 15% of patients without CNS involvement (p = 0.0004), which may be accounted for by nonadherence. In addition, patients with antigenuria above 2.0 ng/mL at 1-year follow-up were 12.82 times (95% confidence interval, 2.91-55.56) more likely to relapse compared to those with antigenuria below 2.0 ng/mL. Discontinuation of antifungal therapy was safe in adherent patients who completed at least 1 year of antifungal treatment, and had CD4 counts >150 cells/mL, HIV RNA <400 c/mL, Histoplasma antigenuria <2 ng/mL (equivalent to <4.0 units in second-generation method), and no CNS histoplasmosis.

    A total of 128 human oral isolates of Candida albicans were collected from asymptomatic healthy carriers (64 isolates); asymptomatic, nonimmunosuppressed, hospitalized patients (25 isolates); immunosuppressed transplant patients (19 isolates); and human immunodeficiency virus-infected patients with symptoms of acquired immunodeficiency syndrome and oral candidiasis (20 isolates). Isolates were serotyped as A or B and tested for reactivity with an agglutinating immunoglobulin M monoclonal antibody (H9). Immunocompetent individuals colonized by oral C. albicans were almost equally likely to carry serotype A as serotype B cells, while immunocompromised individuals were at least twice as likely to be infected by serotype B than serotype A strains. The reactivity of isolates with H9 antibody followed a similar but more distinctive pattern. Approximately half of the strains from immunocompetent individuals reacted strongly with H9, and the remainder reacted weakly. However, up to 75% of the isolates from immunocompromised patients reacted weakly with H9, while the remainder reacted strongly. A correlation between H9 reactivity and the serotypes of these isolates existed (P = 0.16). The correlation between H9 reactivity and immune status was even stronger (P = 0.025). The monoclonal antibody activities described above were determined by agglutination tests during defined phases of C. albicans growth. Expression of antigen at various times during growth of several isolates was confirmed at the cellular level by analysis using fluorescence-activated cell sorting. Despite the correlation between serotype A and H9 reactivity, H9 antigen was not identical to the serotype A antigen because four serotype A strains reacted only weakly with H9 antibody, and one strain reacted strongly with H9 but was serotype B. These data indicate that oral strains of C. albicans from immunocompetent individuals differ as a group from C. albicans isolated from those who are immunosuppressed. PMID

    Cryptococcosis occurs in acquired immunodeficiency syndrome (AIDS) patients with poor compliance to antiretroviral therapy or unaware of their human immunodeficiency virus status who present severe immunosuppression at admission. Consequently, high mortality rates are observed due to disseminated fungal infection. This report presents clinical and postmortem data of AIDS patients with cryptococcosis in a teaching hospital in Brazil. Retrospectively, medical and necropsy records of AIDS patients with cryptococcosis clinically confirmed and/or postmortem verified were reviewed. Clinical data were compared with those of patients presenting a good outcome to evaluate disseminated fungal infection and the agreement between clinical and postmortem diagnosis. At admission, most of the 45 patients with cryptococcal meningitis who died, presented more altered consciousness (P = 0.0047), intracranial increased pressure (P = 0.047), and severe malnutrition (P = 0.0006) than the survivors. Of 29 (64.4%) patients with cryptococcal meningitis, 23 died before week 2 on antifungal therapy, and the other six during the next 3 months. The remaining 16 (35.6%) cases had other diagnoses and died soon after. At necropsy, 31 (68.9%) presented disseminated infection involving two or more organs, whereas 14 (31.1%) cases had meningeal or pulmonary localized infection. The agreement of 64.4% between clinical and postmortem diagnosis was similar to some studies. However, other reports have shown figures ranging from 34% to 95%. Currently, a progressive worldwide decrease of autopsies is worrying because the role of postmortem examination is pivotal to verify or identify the death causes, which contributes to improve the quality of clinical diagnosis and medical training.

    Acute encephalitis caused by Toxoplasma gondi was diagnosed at autopsy in 10 (20.4%) of the 49 patients. All patients had under lying immunodeficiency due to AIDS and showed selective involvement of central nervous system at autopsy. Sexual promiscuity was the risk factor in nine cases while one case had a history of blood transfusion. Diagnosis of toxoplasmosis was hampered by a lack of suspicion that Toxoplasma could be the agent causing necrotising encephalitis. The large number of cases of CNS toxoplasmosis appearing in AIDs patients emphasize the necessity of including toxoplasmosis in the differential diagnosis of encephalitis of unknown aetiology.

    The authors studied thymus specimens taken at autopsy from eight acquired immune deficiency syndrome (AIDS) patients and compared these with those taken from four patients with congenital immunodeficiency (unrelated to an intrinsic thymus defect) and seven patients after allogeneic bone marrow transplantation. In all cases, histology showed a severely involuted architecture, compatible with a debilitating disease before death. There were no major differences between thymus tissue in AIDS patients and in the other patients studied. This argues against the claim expressed in the literature that the epithelial microenvironment incurs particular HIV-1-induced injury in AIDS. This conclusion is substantiated by immunohistochemistry for HIV-1 gag and env proteins, and by hybridohistochemistry for gag/pol and env mRNA of HIV-1. Positive cells were observed only in low numbers, both inside the epithelial parenchyma and in the (expanded) perivascular areas. An interesting finding was the labeling of subcapsular/medullary epithelium in normal uninvoluted thymus by a number of antibodies to HIV-1 gag p17 and p24 proteins. Compatible with this labeling was the staining of epithelial stalks in hyperinvoluted thymuses irrespective of disease category. The previously reported cross-reactivity between HIV-1 core protein and thymosin alpha 1 cannot fully explain this observation, because the epithelium in the hyperinvoluted state is negative for thymosin alpha 1. This study confirms and extends previous reports on the endogenous presence of epitopes of retroviral antigens in thymic epithelium. Images Figure 1 Figure 2 Figure 3 PMID:2474255

    Because human inmmunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) receives more donor funding globally than that for all other diseases combined, some critics allege this support undermines general health care. This empirical study evaluates the impact of HIV/AIDS funding on the primary health care system in Rwanda. Using a quasi-experimental design, we randomly selected 25 rural health centers (HCs) that started comprehensive HIV/AIDS services from 2002 through 2006 as the intervention group. Matched HCs with no HIV/AIDS services formed the control group. The analysis compared growth in inputs and services between intervention and control HCs with a difference-in-difference analysis in a random-effects model. Intervention HCs performed better than control HCs in most services (seven of nine), although only one of these improvements (Bacille Calmette-Guérin vaccination) reached or approached statistical significance. In conclusion, this six-year controlled study found no adverse effects of the expansion of HIV/AIDS services on non-HIV services among rural health centers in Rwanda.

    Necropsy findings in 395 adult patients with the acquired immunodeficiency syndrome (AIDS) who died in Nice, France, between March 1983 and May 1996 were compared retrospectively with antemortem diagnoses, risk factors and number of positive T CD4 lymphocytes at the time of death. Special emphasis on bacterial infections was made in this study. Lesions observed from 1983 through 1989 and from 1990 through 1996 were compared. We assessed the role of organ lesions in the immediate cause of death. The organ system distribution of major opportunistic infections and neoplasms was similar throughout the years of the study. The most common diagnostic disease entities in all organ sites were cytomegalovirus infection, toxoplasmosis and candidiasis. Toxoplasmosis was more common in the intravenous drug abuser group. Bacterial infections were frequent and contributed to the mortality and morbidity of all risk factor groups. Kaposi' sarcoma continued to occur more frequently in the homosexual population. Cytomegalovirus infection remained one of the most common causes of death from 1983 to 1996. Mortality from fungal and bacterial infections, and mycobacteriosis increased in frequency during the course of this study whereas deaths from pneumocystosis declined. The death rate from malignant lymphoma and carcinoma increased after 1989. The clinical cause of death concurred with the pathological cause in 55% of the cases. Lung was the most frequent organ involved followed by the central nervous system the gastrointestinal tract and the heart.

    We explore the links between substance use, misuse, addiction, and dependency1 and sexuality, sexually transmitted diseases (STD), human immunodeficiency virus (HIV), and acquired immune deficiency syndrome (AIDS) to increase our awareness of their interdependence and to identify new ways to perceive, judge, and intervene (or not to) with associated problems. We consider the sociocultural and economic context in which these behaviors occur; the impact these behaviors have on one another; the personal opinions and attitudes; the religious, moral, or political beliefs and agendas; the physiological and fiscal constraints; and theories of rational decision-making and psychological motivation that act to increase or reduce the incidence of these behaviors and their sequellae, while hindering or facilitating prevention, harm reduction, and treatment interventions. Mechanisms of epidemic spread of STDS/HIV/AIDS are presented in the Appendix. Each of these terms are loaded "container concepts" that are culture-bound and stakeholder-driven and whose dimensions are less than consensus-based. They represent a range of meanings, uses, and misuses in an ongoing politicalized area of human and systemic functioning and adaptations.

    The function of macrophage C3 receptors was assessed in vivo by measuring the clearance of C3-sensitized autologous erythrocytes in seven acquired immunodeficiency syndrome (AIDS) patients, eight healthy homosexual men, eight healthy heterosexual men, and four infected controls. Healthy heterosexual men had an initial clearance of 50.1 +/- 2.0% of the inoculum, with a release of a small portion of these cells (10.9 +/- 1.3%) into the circulation. Healthy homosexual men had a greater initial clearance of 66.0 +/- 4.2% (P less than 0.01) followed by a similar release (14.0 +/- 3.3%). AIDS patients had an initial clearance of 60.6 +/- 7.5% but had a relatively large release of cells (25.6 +/- 3.2%) (P less than 0.005 vs. heterosexuals; P less than 0.05 vs. homosexuals), suggesting a failure of macrophage phagocytosis. Infected controls had an initial clearance of 59.4 +/- 4.9%, with a release of 19.6 +/- 3.8% (P = NS vs. AIDS). These data, in addition to Fc-receptor dysfunction, demonstrate a global reticuloendothelial system dysfunction in AIDS patients. This may contribute to their frequent infections with opportunistic pathogens and inappropriate immune responses against these microorganisms. Images PMID:3546375

    Disseminated Mycobacterium avium-intracellulare (MAI) in patients with the acquired immunodeficiency syndrome (AIDS) is usually unresponsive to antimycobacterial therapy. We examined clinical and laboratory characteristics of MAI organisms and their relationship to the length of survival. We studied factors influencing survival and compared these in 76 patients with AIDS with and without MAI. Serum levels of p24 antigen and erythropoietin, and CD4-positive helper T-lymphocytes in blood were assessed in 36 additional patients with various clinical stages of HIV infection. In patients with MAI infection, survival was significantly related only to total lymphocyte count, hematocrit, platelet count, and sex. Of these, hematocrit and total lymphocyte count were the only linear predictors of survival. Anemia was significantly more profound in patients with AIDS and MAI than in the other patients. This anemia in patients with MAI could not be ascribed to increased peripheral destruction of red cells, deficient nutritional factors, or erythropoietin production, HIV viral or bacterial load, or a general effect on other blood elements such as neutrophils or platelets. The influence of MAI on survival in patients with AIDS did depend upon whether the MAI occurred as an index infection or was preceded by other opportunistic infections. Patients with other preceding opportunistic infection lived for a much shorter duration from the time of diagnosis of MAI.

    In north India the number of paediatric cases with acquired immunodeficiency syndrome (AIDS) is on the rise. Most drug combinations used for treatment of AIDS incorporate nevirapine, resistance to which develops very fast if given singly or because of unplanned interruptions. This paper investigates presence of mutations at codon 103 and codon 215 of the HIV pol gene causing resistance to nevirapine and zidovudine (AZT) respectively in 25 children with AIDS. Mutations T215Y and K103N were detected by a nested cum amplification refractory mutation system polymerase chain reaction (ARMS PCR) and the results were confirmed by direct sequencing in five randomly selected cases. Nineteen patients had received nevirapine containing regimen and six were drug naive. Mutation K103N was observed in 56% (14/25) of the children while mutation T215Y was found in none. Two of the six drug naïve children also showed K103N mutation. Thus, Indian children drug naïve or treated with nevirapine containing regimens show a high rate of mutation conferring resistance to nevirapine which calls for a judicious use of nevirapine both in antenatal and postnatal setting.

    The greenhouse effect cools the stratosphere and increases formation of PSC (polar stratospheric cloud) in polar regions and enhances ozone depletion. If the enhanced ozone depletion diffused to lower latitudes, it could increase ultraviolet radiation (UV), which might increase acquired immunodeficiency syndrome (AIDS). Epidemiological studies are made to test this hypothesis. The relation between AIDS prevalence R and latitude {theta}. Comparison of analyses shows that R of Caucasians would be higher than Non-Caucasians at the same {theta}. These trends are similar to those of skin cancers known to be caused by UV. In developing countries poverty, malnutrition, etc., could cause high R, and since most developing countries are located at low {theta}, the low {theta} increase may be due to these factors. However if so in Africa they are about the same and the low {theta} increase would disappear, but data on African countries also show the low {theta} increase and the significant correlation. Some countries at low {theta} have low R, probably because HIV is not prevalent for them. Then the upper envelope of the distribution of R would be cases when HIV is prevalent and UV is most effective. Therefore analyses are repeated using maxima of R within intervals of {theta} of 1, 3 and 5{degree}. In all cases the low {theta} increase and the correlation becomes more significant. These results support the hypothesis that AIDS is promoted by UV.

    Invasive fungal infections (IFIs) represent one of the main causes of morbimortality in immunocompromised patients. Pneumocystosis, cryptococcosis and histoplasmosis are the most frequently occurring IFIs in patients with acquired immunodeficiency syndrome (AIDS). Fungi, such as Candida spp. and Aspergillus spp., may cause severe diseases during the course of an HIV infection. Following the introduction of highly active anti-retroviral therapy, there has been a marked reduction of opportunistic fungal infections, which today is 20-25 % of the number of infections observed in the mid-1990s. This study is an observational and retrospective study aimed at the characterising IFI incidence and describing the epidemiology, clinical diagnostic and therapeutic features and denouement in HIV/AIDS patients. In HIV/AIDS patients, the IFI incidence is 54.3/1,000 hospitalisation/year, with a lethality of 37.7 %. Cryptococcosis represents the main opportunistic IFI in the population, followed by histoplasmosis. Nosocomial pathogenic yeast infections are caused principally by Candida spp., with a higher candidemia incidence at our institution compared to other Brazilian centres.

    A 36-year-old man with a 5-year history of untreated human immunodeficiency virus (HIV) infection had odynophagia for 14 days. Fifteen days earlier, he had begun taking trimethoprim-sulphamethoxazole and combination antiretroviral therapy that included lamivudine, zidovudine, and nelfinavir. He had no history of opportunistic infection. The CD4 lymphocyte count was 67/microL and HIV-RNA level was 359,396 copies/mL. Esophagogastroduodenoscopy revealed a large, well-circumscribed esophageal ulceration 31 cm from the incisors. Histopathologic examination of esophageal biopsy specimens showed cytopathic changes diagnostic of cytomegalovirus (CMV). In situ DNA hybridization was positive for CMV. While combination antiretroviral therapy was continued, the esophageal symptoms resolved within 4 days of endoscopy without specific therapy for CMV. Follow-up endoscopy 4 weeks later revealed a normal-appearing esophagus, and the patient has remained symptom-free for 10 months.

    Middle East Respiratory Syndrome Coronavirus (MERS CoV) may cause severe pneumonia with significant morbidity and mortality, particularly in patients with multiple comorbid condition. MERS CoV pneumonia has not been previously reported in patients with Human Immunodeficiency Virus (HIV). Herein, we report a case of MERS CoV pneumonia with a successful outcome in a patient recently diagnosed with HIV.

    Disseminated cryptococcosis and recurrent oral candidiasis was presented in a-heterosexual AIDS patient. Candida tropicalis (C.tropicalis) was isolated from the oral pseudomembranous plaques and Cryptococcus neoformans (C. neoformans) was isolated from maculopapular lesions on body parts (face, hands and chest) and body fluids (urine, expectorated sputum, and cerebrospinal fluid). In vitro drug susceptibility testing on the yeast isolates demonstrated resistance to fluconazole acquired by C. tropicalis which was a suggestive possible root cause of recurrent oral candidiasis in this patient.

    As a result of improved diagnosis, treatment, and supportive care for HIV-infected patients, AIDS in developed countries has now become a chronic infection with prolonged survival time, but longterm complications are increasing contributors to morbidity and mortality. HIV-infected patients are at increased risk for the development of pulmonary complications, including chronic obstructive pulmonary disease (COPD); however, the mechanisms associated with this increased susceptibility have not been defined. Infectious agents may contribute to the development of COPD by upregulating inflammatory mediators in the lung that act in concert with cigarette smoke to promote lung pathology. Studies in human subjects and non-human primate models of AIDS suggest that the inflammatory response to asymptomatic carriage or colonization by the opportunistic pathogen, Pneumocystis sp. (Pc), is similar to that of COPD, which is characterized by influx of CD8+ T cells, neutrophils, and macrophages into the lungs. We have shown a high frequency of Pc colonization among asymptomatic HIV-infected subjects and in non-HIV infected subjects with COPD. To investigate the role of Pc in the progression of obstructive lung disease in HIV infections, we developed a non-human primate model of Pc colonizatoin and infection in simian immunodeficiency virus (SIV)-infected macaques. These animals develop a prolonged colonization state characterized by a persistent influx of CD8+ T cells and neutrophils, and local increases in IL-8, IFN-gamma, and TNF-alpha. SIV-infected Pc-colonized monkeys show progressive decline in pulmonary function compared to SIV-infected monkeys. We hypothesize that in the context of AIDS-immune dysfunction, Pc colonization induces inflammatory responses leading to changes in pulmonary function and architecture similar to that seen in emphysema. Information gained from these studies will lead to the development of interventions to prevent lung injury associated with Pc

    A 24-year-old male patient with AIDS diagnosed in 1989, and with several episodes of pneumocystosis, was admitted because of a chronic diarrheic syndrome and severe epigastric pain. Endoscopy showed a granular duodenal mucosa. Light microscopy showed a moderate villous atrophy with round-cell inflammatory infiltration of the chorion. Giemsa, Ziehl-Neelsen, and Gram stains showed microsporidial spores measuring between 1.5 and 2 microns in the supranuclear cytoplasm of some enterocytes. Electron microscopy showed sporoblasts and spores consistent with Enterocytozoon bieneusi, with an apparently non-tubular, rather electron-dense polar filament showing up to 7 coils and also a microtubular internal structure with annular disposition, a finding which has not been adequately emphasized in the pertinent literature, probably representing a contractile property of the polar filament, rather than a mere duct for the parasitic sporoplasm to be inoculated.

    Pediatric cryptococcosis has been documented in various organs, but pediatric renal cryptococcosis (RC) remains undocumented to date. The authors report RC in 2 children with AIDS, 7 and 9 years of age, with proteinuria. Both patients, on antiretroviral therapy (ARV) for 28 (patient 1) and 54 (patient 2) weeks each, had secured viral immunosuppression, but immune restoration was realized by patient 1 only. Cryptococcal immune reconstitution inflammatory syndrome (IRIS) was diagnosed on the renal biopsy from patient 1 based on the clinicopathological profile and the presence of segmental glomerular and an interstitial lymphoplasmacytic and granulomatous reaction to Cryptococcus neoformans, with a predominance of capsule-deficient fungal forms. The renal biopsy from patient 2 demonstrated typical HIV-associated nephropathy with focal intratubular and interstitial C neoformans yeasts. Pediatric AIDS-associated renal disease must be expanded to include RC and cryptococcal IRIS, and the kidney must be included as a potential sentinel site of IRIS.

    We studied whether volunteers giving blood to the Greater New York Blood Program (GNYBP) cooperated with procedures implementing public health recommendations intended to decrease the risk of acquired immunodeficiency syndrome (AIDS) transmission by blood transfusion. Predonation medical screening was expanded to exclude donors who might be ill with AIDS. To exclude possible asymptomatic carriers of the disease, members of groups at increased risk of AIDS were asked either not to give blood or to give it for laboratory studies. A confidential questionnaire, administered to all donors after medical screening, provided the vehicle for donors to advise the GNYBP whether their donation was for laboratory studies or for patient transfusion. We found that the number of male donors decreased; AIDS-related questions in medical history led to a 2 percent increase in donor rejections; 97 percent of donors said their blood could be used for transfusions; 1.4 percent said their blood could be used for laboratory studies only; and 1.6 percent did not respond. Only units designated for transfusion were released to hospitals. People who indicated that their donation was for laboratory studies had a higher prevalence of markers for hepatitis B virus and of antibodies to cytomegalovirus. White cell counts and helper/suppressor T lymphocyte ratios were not significantly different in the two groups. We conclude that volunteer donors have cooperated with the established procedures. None of the laboratory assays identified blood units donated by individuals who, based on information about AIDS high-risk groups, designated their donation for laboratory studies.

    The levels of the 2'-5' oligoadenylate enzyme synthetase in extracts of peripheral blood mononuclear cells from individuals with acquired immunodeficiency syndrome (AIDS) and AIDS-related complex (ARC) were measured and compared with synthetase levels in peripheral blood mononuclear cells (PBMs) from healthy heterosexual and homosexual controls. The mean basal synthetase level in heterosexual and homosexual controls was 14 +/- 13 and 12 +/- 9 pmol per hr/10(5) PBMs, respectively. Thirteen individuals with AIDS had a mean basal level of 129 +/- 75 pmol. Serial levels were persistently elevated in six of these individuals over a one- to 10-month period. Twelve of the 13 individuals had antibodies to human T cell lymphotrophic virus-III/lymphadenopathy-associated virus (HTLV-III/LAV). Thirty-three individuals with ARC had a mean basal synthetase level of 68 +/- 84 pmol. Thirty-two of the 33 had antibodies to HTLV-III/LAV. Eleven (33%) have had consistently normal synthetase levels (less than 2 SD above the mean for the homosexual controls, i.e., 30 pmol) over a three- to nine-month follow-up period. Fourteen (42%) had persistently elevated levels over the same period; four (29%) of these developed AIDS during the follow-up period. Eight have had fluctuating levels but have remained clinically well. These studies suggest that persistently elevated synthetase levels in individuals with ARC and antibodies to HTLV-III/LAV indicate progressive virus-induced disease activity. Elevated synthetase levels may be an important prognostic indicator of increased risk of progression to AIDS.

    Background and Objectives: Human immunodeficiency virus (HIV) is a major public health challenge. Unjustified calls for the isolation of patients with HIV infection might further constrain the potential for expansion of clinical services to deal with a greater number of such patients. This infectious illness can evoke irrational emotions and fears in health care providers. Keeping this in view, a study was conducted to assess the knowledge and attitudes related to HIV/acquired immune deficiency syndrome (AIDS) among dental and medical students. Methodology: Descriptive cross-sectional survey of the entire dental and medical undergraduate students from two colleges was carried out using a pretested, self-administered questionnaire. Descriptive statistics such as percentage was used to present the data. Results: Ninety-eight percentage medical and dental undergraduate graduate students knew about HIV transmission in the hospital. Journals and internet were the leading source of information among both medical and dental undergraduates. The majority of respondents discussed HIV-related issues with their classmates. Surprisingly, 38% medical and 52% dental undergraduates think that HIV patient should be quarantined (isolation) to prevent the spread of infection. 68% medical and 60% dental undergraduates are willing to rendering dental/medical care to HIV-infected patients. Relatively large proportion (98%) of participants was willing to participate for HIV prevention program. Conclusion: The knowledge of medical and dental students is adequate, but the attitude needs improvement. Dental and medical students constitute a useful public health education resource. Comprehensive training, continuing education, and motivation will improve their knowledge and attitude, which enable them to provide better care to HIV patients. PMID:26538940

    Case report of bilateral cavernous sinus syndrome due to primary non-Hodgkin lymphoma of the central nervous system in a patient infected by the human immunodeficiency virus. A 51-year-old male patient infected by the human immunodeficiency virus but without antiretroviral treatment developed paralysis of the V and VI cranial nerves. Imaging studies were obtained to investigate an orbital apex and a cavernous sinus syndrome. A computerized tomography scan of the orbit was normal but a high-resolution magnetic resonance imaging demonstrated bilateral enlargement of the cavernous sinus. Although primary lymphoma of the central nervous system is a rare condition, it should be considered in the differential diagnosis in immunocompromised patients who develop ocular motility abnormalities and imaging signs suggestive of infiltrative cavernous sinus lesions.

    The AIDS epidemics is a serious threat to world health. Transmission of infection follows well defined routes: sexual contact with infected people, transfusion of blood or other contaminated products and the transplacental infection. The bulk of cases is due homo or heterosexual contact. Measures to decrease the risk of transmission associated to blood transfusion are already operative in Chile. Campaigns for public education are starting and should be increased. Risky conducts can be decreased by these measures which are the responsibility of society at large.

    A Pneumocystis jiroveci infection-associated mass clinically mimicking a malignancy (ie, pseudotumor) is rare and usually occurs in the lung in association with Pneumocystis pneumonia. Pneumocystis jiroveci pseudotumors of the small intestine are extremely rare and represent an unusual form of disseminated P jiroveci infection. We present a case of small-intestine P jiroveci pseudotumor as an acquired immunodeficiency syndrome-presenting illness in a patient with coinfection with cytomegalovirus, no pulmonary symptoms, and no known risk factors for human immunodeficiency virus infection. This case reinforces the potential importance of cytomegalovirus coinfection in the disseminated form of Pneumocystis infection and illustrates the importance of an expanded differential diagnosis when confronted with a clinically atypical mass lesion.

    Background. Predictors of thyroid dysfunction in HIV are not well determined. This study aimed to determine the prevalence and predictors of thyroid dysfunction in HIV infected Indians. Methods. Consecutive HIV patients, 18-70 years of age, without any severe comorbid state, having at least 1-year follow-up at the antiretroviral therapy clinic, underwent clinical assessment and hormone assays. Results. From initially screened 527 patients, 359 patients (61.44 ± 39.42 months' disease duration), having good immune function [CD4 count >200 cell/mm(3): 90.25%; highly active antiretroviral therapy (HAART): 88.58%], were analyzed. Subclinical hypothyroidism (ScH) was the commonest thyroid dysfunction (14.76%) followed by sick euthyroid syndrome (SES) (5.29%) and isolated low TSH (3.1%). Anti-TPO antibody (TPOAb) was positive in 3.90%. Baseline CD4 count had inverse correlation with TPOAb after adjusting for age and body mass index. Stepwise linear regression revealed baseline CD4 count, TPOAb, and tuberculosis to be best predictors of ScH after adjusting for age, weight, duration of HIV, and history of opportunistic fungal and viral infections. Conclusion. Burden of thyroid dysfunction in chronic HIV infection with stable immune function is lower compared to pre-HAART era. Thyroid dysfunction is primarily of nonautoimmune origin, predominantly ScH. Severe immunodeficiency at disease onset, TPOAb positivity, and tuberculosis were best predictors of ScH.

    We present the pulmonary findings in 36 autopsies of children affected by the acquired immunodeficiency syndrome (AIDS). Twenty-three patients were male and 13 were female, ranging in age between 3 days and 13 years. Twenty children had human immunodeficiency virus (HIV)-positive parents or parents who were at high risk of exposure (intravenous drug abusers and prostitutes), five had a history of transfusion, and one had a history of renal transplantation and blood transfusion. Clinically, the patients presented with recurrent infections, failure to thrive, hepatosplenomegaly, fever, cough, and/or hemoptysis. Histologically, specific infectious processes were the most common finding (75% of cases), with Pneumocystis carinii pneumonia being the most prevalent type of infection, followed by bacterial pneumonia. Neoplastic conditions and lymphoid interstitial pneumonia were less frequent (approximately 10% of cases). In addition, in approximately 10% of the cases the pulmonary findings were non-specific (ie, pulmonary edema and atelectasis) and probably unrelated to HIV infection. Our findings suggest that specific infectious conditions constitute the most common type of pulmonary pathology in children with AIDS. However, because there is a small percentage of children with nonspecific findings, a transbronchial biopsy is important for proper evaluation before institution of therapy.

    Despite increased funding for research on the human immunodeficiency virus (HIV) and the acquired immunodeficiency syndrome (AIDS), neither vaccine nor cure is yet in sight. Surveillance and prevention are essential for disease intervention, and it is recognised that spatio-temporal analysis of AIDS cases can assist the decision-making process for control of the disease. This study investigated the dynamic, spatial distribution of notified AIDS cases in the State of Rio de Janeiro, Brazil, between 2001 and 2010, based on the annual incidence in each municipality. Sequential choropleth maps were developed and used to analyse the incidence distribution and Moran's I spatial autocorrelation statistics was applied for characterisation of the spatio-temporal distribution pattern. A significant, positive spatial autocorrelation of AIDS incidence was observed indicating that municipalities with high incidence are likely to be close to other municipalities with similarly high incidence and, conversely, municipalities with low incidence are likely to be surrounded by municipalities with low incidence. Two clusters were identified; one hotspot related to the State Capital and the other with low to intermediate AIDS incidence comprising municipalities in the north-eastern region of the State of Rio de Janeiro.

    Background: The human immunodeficiency virus (HIV) infection which manifests as acquired immunodeficiency syndrome (AIDS) is a disease involving the defects of the T-lymphocyte arm of the immune system. Certain laboratory parameters such as the cluster of differentiation (CD4) count and clinical parameters have long been used as markers of disease progression. In industrialized countries, many studies show a highly correlation between the incidence of oral lesions and immunosuppression and hence, can be used as a marker of immunosuppression. This might not be applicable to a developing country like India. In this study, efforts have been made to supplement the present knowledge on various aspects of oral manifestations in HIV patients in the Indian subcontinent. Aims: To correlate the oral manifestations in HIV/AIDS patients to the level of circulating CD4+ T-lymphocyte count and their effect in anti-retroviral therapy (ART). Subjects and Methods: A total of 104 HIV positive patients were examined for oral lesions. The CD4 count estimated on the same day by fluorescent activated cell sort count machine was then correlated with various oral lesions. Results: Oral manifestations appeared when CD4 count decreased below 500 cells/mm3. Moreover, oral lesions found at different stages showed very strong correlation to their respective CD4 count. Furthermore, there was considerable decline in the incidence of oral manifestations in patients undergoing highly active ART. Conclusions: Oral manifestations are highly predictive markers of severe immune deterioration and disease progression in HIV patients. PMID:27994425

    A 35-years-old right-handed man admitted to our hospital with a worsening of dysarthria, left facial palsy and left hemiparesis for 2 days. Acquired immunodeficiency syndrome (AIDS) was diagnosed when he was 28 years old. At that time, he also was treated for syphilis. After highly active antiretroviral treatment (HAART) was introduced at the age of 35 years old, serum level of human immunodeficiency virus (HIV) was not detected, but the number of CD4+ T cells was still less than 200/μl. He had no risk factors of atherosclerosis including hypertension, diabetes and hyperlipidemia. He had neither coagulation abnormality nor autoimmune disease. Magnetic resonance imaging (MRI) showed acute ischemic infarction spreading from the right corona radiate to the right internal capsule without contrast enhancement. Stenosis and occlusion of intracranial arteries were not detected by MR angiography. Although argatroban and edaravone were administered, his neurological deficits were worsened to be difficult to walk independently. Cerebrospinal fluid (CSF) examination showed a mild mononuclear pleocytosis (16/μl). Oligoclonal band was positive. The titer of anti-varicella zoster virus (VZV) IgG antibodies was increased, that indicated VZV reactivation in the central nervous system (CNS), although VZV DNA PCR was not detected. Therefore, acyclovir (750 mg/day for 2 weeks) and valaciclovir (3,000 mg/day for 1 month) were administered in addition to stroke therapy. He recovered to be able to walk independently 2 month after the admission.Angiography uncovered a saccular aneurysm of 3 mm at the end of branch artery of right anterior cerebral artery, Heubner artery, 28 days after the admission. We speculated that VZV vasculopathy caused by VZV reactivation in CNS was involved in the pathomechanism of cerebral infarction rather than HIV vasculopathy in the case.

    The accessibility of high active antiretroviral therapy (HAART) for local human immunodeficiency virus (HIV) patients is improving in Rwanda. It is well known that this therapy is associated with serious adverse effects, such as metabolic and morphologic changes. One of the recommended preventive modalities for these complications is participation in physical activity. The current study aims to determine the anthropometric profile and physical activity levels among people living with HIV and receiving HAART in Kigali, Rwanda. The study was a cross-sectional, descriptive quantitative survey. The participant's levels of physical activity participation and their association with anthropometric profiles were measured, using a structured self-administered questionnaire for 407 clients passing through the clinics. Of the participants, approximately 70% were inactive and in addition, 40% were obese and 43% overweight. Obesity was found to be strongly associated with inactivity. Lack of motivation, and time as well as fear of worsening the disease were found to be barriers to participation in physical activity.

    An atypical case of acquired immunodeficiency syndrome-associated mucocutaneous lesions due to Leishmania braziliensis is described. Many vacuolated macrophages laden with amastigote forms of the parasite were found in the lesions. Leishmanin skin test and serology for leishmaniasis were both negative. The patient was resistant to therapy with conventional drugs (antimonial and amphotericin B). Interestingly, remission of lesions was achieved after an alternative combined therapy of antimonial associated with immunotherapy (whole promastigote antigens). Peripheral blood mononuclear cells were separated and stimulated in vitro with Leishmania antigens to test the lymphoproliferative responses (LPR). Before the combined immunochemotherapy, the LPR to leishmanial antigens was negligible (stimulation index - SI=1.4). After the first course of combined therapy it became positive (SI=4.17). The antigen responding cells were predominantly T-cells (47.5%) most of them with CD8+ phenotype (33%). Very low CD4+ cells (2.2%) percentages were detected. The increased T-cell responsiveness to leishmanial antigens after combined therapy was accompanied by interferon-g (IFN-g) production as observed in the cell culture supernatants. In this patient, healing of the leishmaniasis lesions was associated with the induction of a specific T-cell immune response, characterized by the production of IFN-g and the predominance of the CD8+ phenotype among the Leishmania-reactive T-cells.

    To respond to the human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) epidemic in China, the integration of antiretroviral therapy (ART) and traditional Chinese medicine (TCM) has important implications in health outcomes, especially in China where the use of TCM is widespread. The National Free TCM Pilot Program for HIV Infected People began in 5 provinces (Henan, Hebei, Anhui, Hubei, and Guangdong) in 2004, and quickly scaled up to 19 provinces, autonomous regions, and municipalities in China including some places with high prevalence, 26,276 adults have been treated thus far. Usually, people with HIV infection seek TCM for four main reasons: to enhance immune function, to treat symptoms, to improve quality of life, and to reduce side effects related to medications. Evidences from randomized controlled clinical trials suggested some beneficial effects of use of traditional Chinese herbal medicine for HIV infections and AIDS. More proofs from large, well-designed, rigorous trials is needed to give firm support. Challenges include interaction between herbs and antiretroviral drugs, stigma and discrimination. The Free TCM Program has made considerable progress in providing the necessary alternative care and treatment for HIV-infected people in China, and has strong government support for continued improvement and expansion, establishing and improving a work mechanism integrating Chinese and Western medicines.

    Strains of the Mycobacterium avium complex (MAC) yield opaque and transparent colonial variants when cultivated in vitro. The transparent variants are more virulent than the opaque for animals, but little is known about the respective roles of these colonial variants in humans. To assess which variant infects humans, various blood fractions from eight patients with MAC bacteremia were plated directly onto 7H10 agar. In cell fractionation studies, all the M. avium complex CFU were associated with leukocytes and none were found free in plasma. All colonies on the primary culture plate exhibited the transparent phenotype. However, during subculture in 7H9 broth or on Lowenstein-Jensen agar, opaque variants appeared in seven of eight strains. Isogenic pairs of transparent and opaque variants were prepared and used to infect in vitro human monocyte-derived macrophages from healthy seronegative individuals. Transparent variants invariably grew inside macrophages, but only one of seven opaque variants did so. These observations indicate that the bacteremia of M. avium complex in acquired immunodeficiency syndrome patients consists exclusively of the transparent variants, perhaps because these variants are able to multiply inside macrophages. In contrast, opaque variants appear after in vitro subculture and are controlled by human macrophages, consistent with their reduced virulence in animals. Images PMID:2370109

    Health professionals caring for people living with human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) show poor or negative attitudes because of fear of contagion. Therefore, it is important to know the attitudes of midwives' and nurses' towards people living with HIV/AIDS. The aim of this descriptive and cross-sectional study is to assess the attitudes of Turkish midwives and nurses working at hospitals to people living with HIV/AIDS and to identify factors that affect these attitudes. A group of 46 midwives and 192 nurses working in hospitals were included in the study. Data were collected through AIDS Attitude Scale. Age, professional experience, number of children and marital status influenced the attitudes of the participants towards people living with HIV/AIDS. We concluded that higher level of education appear to positively influence the attitudes of the participants. Education programmes including evidence-based nursing implications might be planned to improve positive attitudes and to prevent stigmatization of people living with HIV/AIDS.

Lack of motivation, and time as well as fear of worsening the disease were found to be barriers to participation in physical activity. PMID:24521093

    Responses from 125 of 290 nursing undergraduates indicated their attitudes ranged from most to least positive regarding people with AIDS acquired through blood transfusion, heterosexual activity, homosexual activity, and needle sharing. Homophobia, fear of AIDS, and perceived susceptibility were inversely related with intention to care for AIDS…

    Background: The present study was directed to evaluate the forms of oropharyngeal candidiasis (OPC) and their correlation with CD4+ cell counts in human immunodeficiency virus (HIV) patients. Materials and Methods: This was a descriptive and analytical cross-sectional study carried out for a 2-year period, in which quantitative data collection methods were used. 50 patients with HIV infection were evaluated. Relationship between OPC and CD4+ was investigated. Results: Five different clinical forms were noticed on examination: pseudomembranous candidiasis 20/38 (P) was the most common one (52.6%) followed by erythematous 5/38 (13.15%), angular cheilitis 5/38 (13.15%) (AC), a combination of AC and E 4/38 (10.52%) or AC, E and P 4/38 (10.52%). Candida albicans was the most frequent specie isolated in 35 cases of OPC (92%). Candida tropicalis was isolated in 2 cases (5.26%) and Candida glabrata in 1 case (2.64%). The majority of patients with OPC had cell counts 28/38 (73%) <200 cells/mm3, followed by 9/38 (23%) at CD4+ cell counts of 201-499 cells/mm3. Conclusion: Oral Candida colonization and invasive infection occur more frequently in HIV-positive patient and is significantly more common in patients with CD4+ cell counts <200 cell/mm3.

    Background Natural killer (NK) cells play an important role in innate immunity and are involved in the host defense against human immunodeficiency virus (HIV) infection. This study examines the potential role of three underlying regulatory systems that have been under investigation in central nervous system research as well as immune and viral research: serotonin, neurokinin, and glucocorticoid systems. Methods Fifty-one HIV-seropositive subjects were recruited to achieve a representative sample of depressed and nondepressed women. The effects of a selective serotonin reuptake inhibitor (SSRI), a substance P (SP) antagonist, and a glucocorticoid antagonist on NK cell function were assessed in a series of ex vivo experiments of peripheral blood mononuclear cells from each HIV-seropositive subject. Results Natural killer cell cytolytic activity was significantly increased by the SSRI citalopram and by the substance P antagonist CP-96345 relative to control conditions; the glucocorticoid antagonist, RU486, showed no effect on NK cytotoxicity. Our results suggest that the effects of the three agents did not differ as a function of depression. Conclusions Our findings provide evidence that NK cell function in HIV infection may be enhanced by serotonin reuptake inhibition and by substance P antagonism. It remains to be determined if HIV-related impairment in not only NK cytolytic activity but also NK noncytolytic activity can be improved by an SSRI or an SP antagonist. Clinical studies are warranted to address these questions and the potential roles of serotonergic agents and SP antagonists in improving NK cell immunity, delaying HIV disease progression, and extending survival with HIV infection.

    During the period from January to December 1987, 2,191 serum samples were collected from different groups of the population in the Ivory Coast (1,126 healthy people selected from the general population, 416 blood donors, 112 healthy anti-HIV carriers, 173 AIDS patients, and 364 patients suffering from icterigenic hepatitis) and tested for anti-HIV (HIV-1 and HIV-2) antibodies, HBsAg, HBeAg, delta antigen (HDAg), and anti-delta (anti-HD) antibody. Anti-HIV antibodies were found in 30 (2.6%) of the general population. 55 (13.2%) blood donors, and 93 (25.5%) patients suffering from icterigenic hepatitis. HBsAg was observed in 103 (9.1%) of the general population, 45 (10.8%) blood donors, 15 (13.4%) healthy anti-HIV carriers, 59 (34.1%) AIDS patients, and 45 (40%) icterigenous hepatitis patients. The simultaneous presence of anti-HIV and HBsAg was noted in 4 (0.4%) of the general population, 8 (2%) blood donors, 15 (13.4%) healthy anti-HIV carriers, 59 (34.1%) AIDS cases, and 36 (10%) patients suffering from icterigenic hepatitis. A high prevalence of HBeAg and serological markers of infection by the delta agent were noted in the different groups. HDAg was noted only among AIDS patients or those suffering from icterigenic hepatitis, with a higher frequency among anti-HIV carriers. Our conclusion from this study is that healthy anti-HIV carriers are no more likely to be HBsAg carriers than the HIV-seronegative subjects. However, immunodeficiency induced previously by HIV infection is likely to be responsible for the high prevalence of HBsAg among AIDS patients.

    The objective of this study was to assess the prevalence and pattern of neuropsychological impairment in cohorts of human immunodeficiency virus (HIV)-infected individuals across pre- and post-HAART (highly active antiretroviral therapy) eras. Two cohorts of HIV-infected individuals attending tertiary referral hospital outpatient clinics were studied. The cohorts represented two eras of antiretroviral medication: monotherapy (n = 51) and HAART (n = 90). Each was compared in nine neuropsychological domains in regard to the prevalence as well as pattern of neuropsychological impairment. Because the authors intended to characterize the prevalence and pattern of neuropsychological deficits in nondemented advanced HIV-infected individuals, patients with a current diagnosis of acquired immunodeficiency syndrome (AIDS) dementia complex were not included. The prevalence of impairment was not significantly different across pre-HAART and HAART eras using a standard criterion to define impairment: -2 SD in two neuropsychological measures (41.1%/38.8%). Prevalence of deficits was not significantly reduced in patients with undetectable plasma viral load. The pattern of neuropsychological impairment was different across pre-HAART and HAART eras, with an improvement in attention, verbal fluency, visuoconstruction deficits, but a deterioration in learning efficiency and complex attention. This change remained even in patients with an undetectable plasma viral load, although the severity was partially diminished. Neuropsychological deficits remain common in the HAART era, essentially uninfluenced by HAART. The finding that some neuropsychological functions are improving while other are deteriorating indicates that these deficits do not reflect "burnt out" damage but rather that there is an active intracerebral process occurring, the nature of which is still to be determined.

    The Human Immunodeficiency Virus (HIV) pandemic is on the increase with the highest burden in sub-Saharan Africa. This descriptive cross-sectional study was carried out in 2008 to assess the knowledge, self-perception of risk of contracting HIV infection and risky sexual practices among patients attending some out-patient clinics at the University Teaching Hospital, Ado-Ekiti, Ekiti State, Nigeria. The knowledge on the modes of transmission and methods of prevention of HIV was high. Although, 53.0% of the study participants perceived themselves not to be at risk of contracting HIV infection, 80.6% were engaged in risky sexual practices within a year preceding the study. Significantly more participants with multiple sexual partners, past and present history of Sexually Transmitted Infections (STI) perceived themselves not to be at risk (P= 0.001, 0.008 and 0.001 respectively). Effective strategies must therefore be developed, to enhance risk-perception since poor risk-perception is known to mitigate behavioral change.

    Background: Although modification of behavioral practices among human immunodeficiency virus (HIV)-affected patients is important in decreasing HIV disease transmission, the knowledge, attitude, and perception studies about HIV infection rarely include persons living with HIV/acquired immuno deficiency syndrome (AIDS). Aims: To assess knowledge, attitude, and perceptions of persons living with HIV/AIDS for the disease and other epidemiological aspects. Materials and Methods: One-hundred and fifty consecutive persons living with HIV/AIDS were enrolled for this questionnaire-based cross-sectional, descriptive study. Results: These 150 patients comprised 93 men and 57 women, aged between 14 and 78 (mean 37.13) years. The majority, 112 (74.67%) patients were between 20 and 50 years of age and 116 (77.3%) patients were either illiterate or high-school dropouts. Drivers, laborers, and self-employed comprised 69 (74.2%) patients among affected males. Only 129 (86%) respondents had heard about HIV/AIDS and knew about its heterosexual transmission. Ninety-eight (65.3%) respondents were aware of disease transmission from infected blood or needle pricks. Interestingly, 106 (70.7%) respondents were aware of the importance of using condom in preventing disease transmission. Television/radio was the most common sources of information for 135 (90%) patients. Nearly, 69% respondents disfavored disclosing their disease to friends/colleagues fearing stigmatization. Conclusions: Information, education, and communication activities are imperative to educate persons living with HIV/AIDS about life-long nature of the disease, modes of its transmission, and significance of preventive measures to bridge the gaps in their knowledge. While improvement in individual economic status, education, and health services remains highly desirable, mass media can play a pivotal role in creating awareness among masses. PMID:27890953

    The human immunodeficiency virus and acquired immune-deficiency syndrome (HIV/AIDS) is still a 'family crises' which marks the beginning of the deterioration of the family unit and the trauma in the emotional, psychological and material lives of both the mother and child. In South African context where the majority of HIV-positive mothers are young single women who live in extended families, disclosure to the sexual partner alone is not an adequate condition for the success of prevention of mother to child transmission (PMTCT). In South Africa, close to one in three women who attend antenatal clinics are HIV positive. KwaZulu-Natal is one of the worst affected provinces, where as many as 40-60% of pregnant women attending antenatal services are living with HIV infection. The study sought to investigate the link between the home environment and its contribution to the success of the programme on PMTCT of HIV/AIDS. A qualitative, explorative, descriptive and contextual study was used in this study to explore whether the home environment for the support system is available for the HIV-positive women on the PMTCT programme. The population of this study included all women who have undergone counselling and tested HIV positive and who have joined the programme on PMTCT of HIV/AIDS in a specific hospital in KwaZulu-Natal Province. Although 14 women agreed to participate in the study, only 10 women were interviewed as saturation was attained. Data were collected using semi-structured interview schedule. Interviews were audio-taped and field notes were taken. Content analysis was used and it was done manually. This study revealed that one of the major issues still surrounding HIV/AIDS and PMTCT is that of non-disclosure, selective disclosure and the stigma and discrimination that surrounds this disease.

    The diagnosis of cryptococcal infection was established in 3 patients with AIDS. Infection was meningo-encephalic in all and presented a violent outset. The chemical characteristics of the CSF were normal. Detection of cryptococcal antigen, presence of encapsulated yeast forms revealed by india-ink staining and positive cultures allowed a definitive diagnosis. Response to therapy with amphotericin B alone or in combination with 5-fluorocytosine was poor. A maintenance therapy with fluconazole is recommended.

    Background Studies show that nearly 40 million people are living with human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) around the world and since the beginning of the epidemic, about 35 million have died from AIDS. Heterosexual intercourse is the most common route for transmission of HIV infection (85%). People with a sexually transmitted infection (STI), such as syphilis, genital herpes, chancroid, or bacterial vaginosis, are more likely to obtain HIV infection during sex. On the other hand, a patient with HIV can acquire other infections such as hepatitis C virus (HCV) and hepatitis B virus (HBV) and also STIs. Co-infections and co-morbidities can affect the treatment route of patients with HIV/AIDs. Sometimes, physicians should treat these infections before treating the HIV infection. Therefore, it is important to identify co-infection or comorbidity in patients with HIV/AIDS. Objectives This study was conducted in order to understand the prevalence of HIV/AIDS/STI co-infection. Patients and Methods In this cross-sectional study, we evaluated all HIV/AIDS patients who were admitted to the infectious wards of Boo-Ali hospital (Southeastern Iran) between March 2000 and January 2015. All HIV/AIDS patients were studied for sexually transmitted infections (STI) such as syphilis, gonorrhea, hepatitis B virus (HBV) and genital herpes. A questionnaire including data on age, sex, job, history of vaccination against HBV, hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), hepatitis B surface antigen (anti-HBs), HCV-Ab, venereal disease research laboratory (VDRL) test, fluorescent treponemal antibody absorption (FTA-Abs) test, and urine culture was designed. Data was analyzed by the Chi square test and P values of < 0.05 were considered significant. Results Among the 41 patients with HIV/AIDS (11 females and 30 males; with age range of 18 to 69 years) five cases (12.1%) had a positive test (1:8 or more) for

    Histoplasma capsulatum var. capsulatum infection is rare outside disease-endemic areas. Clinical presentation and outcome of acquired immunodeficiency syndrome-related histoplasmosis are unknown in non-endemic areas with wide access to highly active anti-retroviral therapy (HAART). Retrospective analysis of cases recorded at the French National Reference Center for Mycoses and Antifungals during two decades: pre-HAART (1985-1994) and HAART (1997-2006). Clinical features and outcome of all adults with proven acquired immunodeficiency syndrome-related histoplasmosis were compared between the two periods. One hundred four patients were included (40 during the pre-HAART era and 64 during the HAART era). Diagnosis was established a mean of 62 days after onset of symptoms. One-year overall mortality rates decreased from 53% (pre-HAART era) to 22% (HAART era). Diagnosis during the pre-HAART era and an older age were the only independent factors associated with death. Histoplasmosis is a rare invasive fungal infection outside disease-endemic areas. Its prognosis improved significantly during the HAART era.

    Three specific pathogen-free cats experimentally infected with feline immunodeficiency virus (FIV) strains Petaluma, TM1 and TM2, respectively were observed for over 8 years. Without showing any significant clinical signs of immunodeficiency syndrome (AIDS) for 8 years and 4 months of asymptomatic phase, the Petaluma-infected cat exhibited severe stomatitis/gingivitis, anorexia, emaciation, hematological and immunological disorders such as severe anemia, lymphopenia, thrombocytopenia, and decrease of CD4/CD8 ratio to 0.075, and finally died with hemoperitoneum at 8 years and 8 months post-infection. Histopathological studies revealed that the cat had systemic lymphoid atrophy and bone marrow disorders indicating acute myelocytic leukemia (aleukemic type). Plasma viral titer of the cat at AIDS phase was considerably high and anti-FIV antibody titer was slightly low as compared with the other FIV-infected cats. In addition, immunoblotting analysis using serially collected serum/plasma samples of these cats revealed that antibodies against FIV proteins were induced in all the infected cats, however in the Petaluma-infected cat anti-Gag antibodies disappeared during the asymptomatic period. These results suggested that plasma viral load and anti-FIV Gag antibody response correlated with disease progression, and supported FIV-infected cats as a suitable animal model of human AIDS.

    Acquired immunodeficiency syndrome (AIDS) is reviewed for dental practitioners, with an emphasis on oral findings; the clinical course, diagnosis, reporting, treatment, prognosis, transmission, and epidemiology are also covered. HIV infection has an incubation period that may be associated with glandular fever, a prodrome called AIDS-Related Complex (ARC) characterized by lymphadenopathy, low fever, weight loss, night sweats, diarrhea, oral candidosis, nonproductive cough and recurrent infections. AIDS is characterized by opportunistic infections. Over 50% present with pneumocystis carinii pneumonia, 21% with Kaposi's sarcoma, and 6% have both. The AIDS virus causes direct neurological symptoms in some cases. Oral candidosis (thrush) in a young male without a local cause such as xerostomia or immune suppression is strongly suggestive of AIDS. Other oral manifestations are severe herpes simplex, varicella-zoster, Epstein-Barr virus, cytomegalovirus, venereal warts, aphthous ulceration, mycobacterial oral ulcers, oral histoplasmosis, sinusitis and osteomyelitis of the jaw. Hairy leukoplakia, usually seen on the lateral border of the tongue, is probably caused by Epstein-Barr virus. Kaposi's sarcoma, an endothelial cell tumor, is characteristic of AIDS, and in 50% of patients is oral or perioral. Cervical lymph node enlargement will be seen in those with ARC as well as AIDS. No guidelines have been issued by the Department of Health and Social Security for dental surgeons in the UK for reporting AIDS cases. Although HIV virions have been isolated from saliva, there are no known incidents of transmission via saliva. HIV is less likely to be transmitted by needle stick injuries than, for example hepatitis B (25% risk), especially if the blood is from a carrier rather than a full blown AIDS case.

    The goal of this presentation is the description of the epidemiologic evolution and changes in natural history of the human immunodeficiency virus infection (HIV) epidemic itself and its relation with the acquired immunodeficiency syndrome-related lymphoma (ARL). We have started with the description of the world's state of the HIV epidemic, its features since the first case report in the United States of America in 1981, through the peak of new diagnoses in 1993 until the event that changed the natural history of the disease: the era of the widespread use of the highly active antiretroviral therapy (HAART), introduced in 1995 in the world and in 1997 in our country. The widespread introduction of HAART led to dramatic reductions in AIDS related mortality and morbidity throughout the developed world with a marked fall in the incidence of the major opportunistic infections in AIDS. We describe the main risk factors for the development of ARL, and the prognostic factors for survival and response to treatment. There is no clear definition in the literature of the roll that has played the use of HAART in relation to survival and response to treatment in ARL, but there is evidence that the basal count of CD4 cells has increased with HAART, leading to a better survival and response in ARL. The debate regarding this issue is surely affected by factors such as degree of antiretroviral treatment compliance, antiretroviral therapy resistance and chemotherapy heterogeneity. Finally we present the preliminary results of the analysis of our experience in ARL from 1986 to 2003.

    Reported herein is the first case of Leishmania-human immunodeficiency virus (HIV) coinfection in Ecuador. In Ecuador, HIV infections overlap endemic areas of leishmaniasis. Immunosuppression is a well-established risk factor for developing severe disease. This is a severe case of a 32-year-old man presenting with disseminated pleomorphic ulcers, papules, and cutaneous plaque-like lesions over his whole body. Numerous amastigotes were observed in both skin scrapings and biopsies. The sequence of the cytochrome b gene confirmed the presence of Leishmania guyanensis The patient was treated but failed to respond to meglumine antimoniate and amphotericin B. Six months later, the patient died due to bacterial septic shock.

    We studied 55 patients with acquired immunodeficiency syndrome (AIDS) and neurotoxoplasmosis (group 1), 37 patients with AIDS and neurological involvement due to another etiology (group 2) and 18 anti-HIV-negative individuals with neurological manifestations, by searching for anti-T. gondii IgG, IgA and IgM immunoglobulins in serum, cerebrospinal fluid (CSF)and saliva, using ELISA. The negative predictive value of the test for IgG in serum was 100% and in CSF, 92.4%. There was no difference among the three groups studied regarding IgA in serum. For IgA, in CSF the test reached 72.7% specificity (p<0.05). In saliva, only the detection of IgG was found to be correlated with a diagnosis of neurotoxoplasmosis. We emphasize that the absence of anti-T. gondii IgG antibodies in serum and CSF strongly indicates the absence of a diagnosis of neurotoxoplasmosis and that specific IgA immunoglobulins in CSF and IgG in saliva may represent two auxiliary markers for the differential diagnosis of toxoplasmic encephalitis in AIDS.

    Neurologic signs and symptoms may represent the initial presentation of AIDS in 10-30% of patients. Movement disorders may be the result of direct central nervous system infection by human immunodeficiency virus (HIV) or the result of opportunistic infections. We report the case of a 59 years old woman who had hemichorea-hemiballismus subsequently found to be secondary to a cerebral toxoplasmosis infection revealing HIV infection. Movement disorders, headache and nausea were resolved after two weeks of antitoxoplasmic treatment. Brain MRI control showed a marked resolution of cerebral lesion. Occurrence of hemichorea-ballismus in patient without familial history of movement disorders suggests a diagnosis of AIDS and in particular the diagnosis of secondary cerebral toxoplasmosis. Early recognition is important since it is a treatable entity.

    Varicella-zoster virus (VZV) infections have declined in many industrialized countries due to vaccination with the attenuated Oka strain virus. Rare cases of severe, disseminated vaccine-strain VZV infection have occurred in the immunocompromised, although rarely in HIV-infected persons. We describe a man with previously-undiagnosed human immunodeficiency virus (HIV) infection who received VZV vaccination and subsequently presented to a combat hospital in Afghanistan with disseminated varicella, respiratory failure, and sepsis. The patient recovered with ventilator and hemodynamic support, intravenous acyclovir, and empiric antibiotic therapy. DNA sequencing detected Oka strain virus from patient blood specimens. Although safe in most populations, the VZV vaccine may cause life-threatening disease in immunocompromised patients. Improved detection of HIV infection may be useful in preventing such cases.

    Virulence of Rhodococcus equi strains from 20 humans in Brazil was investigated by using a polymerase chain reaction to characterize isolates as virulent (VapA), intermediately virulent (VapB), and avirulent. Nine isolates were obtained from human immunodeficiency virus (HIV)-positive patients, six from HIV-negative patients, and five from patients of unknown status. Five isolates were VapB positive, four were VapA positive, and eleven were avirulent. Among the nine isolates from HIV-positive patients, five contained VapB plasmids and two contained VapA plasmids. Five VapB-positive isolates had the type 8 virulence plasmid. Eleven of the patients had a history of contact with livestock and/or a farm environment, and none had contact with pigs.

    We report paired strains of Leishmania parasites, one from the viscera and the other from skin lesions that were isolated from three patients with visceral leishmaniasis and disseminated cutaneous leishmaniasis that were co-infected with human immunodeficiency virus. The causative parasites were characterized by polymerase chain reaction-restriction length polymorphism of the ribosomal DNA internal transcribed spacer 1 and by a panel of multilocus microsatellite markers. We demonstrated that the causative agent was Leishmania donovani in all cases, irrespective of the phenotype of the disease. The paired strains from viscera and skin lesions of the same patients showed genetic identity across the 14 microsatellite markers investigated. These findings demonstrate that the skin lesions in these human immunodeficiency virus-positive patients with visceral leishmaniasis were caused by dissemination of viscerotropic L. donovani parasites as a consequence of severe immunosuppression. However, in all three patients, rapid clearance of the skin lesions was observed after antimonial therapy.

    Background: Human immunodeficiency virus (HIV) infection remains a global health problem, although the development of highly active antiretroviral therapy (HAART) has significantly modified the course of HIV disease into a manageable disease with improved quality-of-life mainly in the developed countries. Very few studies are available regarding effect of HAART on oral lesions in developing countries like India. Aims and Objectives: The aim was to document and compare oral lesions in HIV-seropositive patients before and after HAART. Materials and Methods: Oral manifestations were recorded in 320 HIV seropositive patients attending to the Voluntary Counseling and Confidential Testing Centre at the Government General Hospital, Guntur, before and after treating with HAART and the results were statistically analyzed using Student's t-test and Chi-square test. Results: Oral Candidiasis was significantly reduced in patients under HAART after 3 months. Furthermore, there was decreased incidence of periodontal diseases, but increased hyperpigmentation in patients undergoing HAART. Conclusion: The oral manifestations of HIV infection have changed due to the advent of HAART. Many opportunistic infections have resolved as a result of an improved immune system. Though the risk of hyperpigmentation in those with HAART has increased the prevalence of oral candidiasis and periodontal diseases were less in patients who had access to HAART. PMID:26392652

    Passive immunotherapy with polyclonal or hyperimmune serum immunoglobulin G (IgG) preparations provides an efficient means of protecting immunocompromised patients from microbial infections. More recently, the use of passive immunotherapy to prevent or to treat established infections with the human immunodeficiency virus (HIV) has gained much attention, due to promising preclinical data obtained in monkey and humanized mouse in vivo model systems, demonstrating that the transfer of HIV-specific antibodies can not only prevent HIV infection, but also diminish virus load during chronic infection. Furthermore, an array of broadly neutralizing HIV-specific antibodies has become available and the importance of the IgG constant region as a critical modulator of broadly neutralizing activity has been demonstrated. The aim of this review is to summarize the most recent findings with regard to the molecular and cellular mechanisms responsible for antibody-mediated clearance of HIV infection, and to discuss how this may help to improve HIV therapy via optimizing Fcγ-receptor-dependent activities of HIV-specific antibodies.

    Summary Tuberculosis (TB), caused by Mycobacterium tuberculosis (M.tb) and a few related mycobacteria, is a devastating disease, killing more than a million individuals per year worldwide. However, its pathogenesis remains largely elusive, as only a small proportion of infected individuals develop clinical disease either during primary infection or during reactivation from latency or secondary infection. Subacute, hematogenous, and extrapulmonary disease tends to be more frequent in infants, children, and teenagers than in adults. Life-threatening primary TB of childhood can result from known acquired or inherited immunodeficiencies, although the vast majority of cases remain unexplained. We review here the conditions conferring a predisposition to childhood clinical diseases caused by mycobacteria, including not only M.tb but also weakly virulent mycobacteria, such as BCG vaccines and environmental mycobacteria. Infections with weakly virulent mycobacteria are much rarer than TB, but the inherited and acquired immunodeficiencies underlying these infections are much better known. Their study has also provided genetic and immunological insights into childhood TB, as illustrated by the discovery of single-gene inborn errors of IFN-γ immunity underlying severe cases of TB. Novel findings are expected from ongoing and future human genetic studies of childhood TB in countries that combine a high proportion of consanguineous marriages, a high incidence of TB, and an excellent clinical care, such as Iran, Morocco, and Turkey.

    To analyze the clinical features of AIDS-related Kaposi's sarcoma (AIDS-KS) patients in Xinjiang Autonomous Region and the impact of CD4 (+)T lymphocyte count, highly active antiretroviral therapy (HAART) and systemic chemotherapy on the prognosis. The clinical information of 80 AIDS-KS patients admitted in Sixth People's Hospital of Xinjiang Autonomous Region from January 2008 to August 2014 was retrospectively reviewed. Population characteristics, extent of lesions, KS progress, CD4 (+)T lymphocyte count, combined opportunistic infections, treatment and prognosis of these patients were analyzed. The 80 patients were divided into five groups according to treatment methods, including HAART, HAART + chemotherapy, chemotherapy + HAART, chemotherapy, and untreated groups. The efficacy and prognosis of the five groups were compared. Among the 80 patients, 74 (92.50%) patients were Uygur. The average age was 39.5±9.9 years and male-to-female ratio was 3:1. The median of baseline CD4 (+)T lymphocyte count was 152.5 cells/μL and the interquartile was 233.25 cells/μL. CD4 (+)T lymphocyte counts were significantly increased after treatment in HAART, HAART + chemotherapy, and chemotherapy + HAART groups (P < 0.05). CD4 (+)T lymphocyte count in chemotherapy groups was significantly reduced after treatment (P < 0.05). The untreated group had the highest mortality rate (33.3%). In HAART group, KS-associated immune reconstitution inflammatory response syndrome (KS-IRIS) appeared in 45.5% cases and 2 death cases were caused by KS-IRIS. In Xinjiang Autonomous Region, the incidence of AIDS-KS is high in young Uygur male people. HAART followed by chemotherapy has ideal efficacy, reduces the incidence of KS-IRIS and improves the prognosis.

    Human immunodeficiency virus (HIV)-positive patients have a greater prevalence of coinfection with human papillomavirus (HPV) is of high oncogenic risk. Indeed, the presence of the virus favours intraepithelial squamous cell lesion progression and may induce cancer. The aim of this study was to evaluate the prevalence of HPV infection, distribution of HPV types and risk factors among HIV-positive patients. Cervical samples from 450 HIV-positive patients were analysed with regard to oncotic cytology, colposcopy and HPV presence and type by means of polymerase chain reaction and sequencing. The results were analysed by comparing demographic data and data relating to HPV and HIV infection. The prevalence of HPV was 47.5%. Among the HPV-positive samples, 59% included viral types of high oncogenic risk. Multivariate analysis showed an association between HPV infection and the presence of cytological alterations (p = 0.003), age greater than or equal to 35 years (p = 0.002), number of partners greater than three (p = 0.002), CD4+ lymphocyte count < 200/mm3 (p = 0.041) and alcohol abuse (p = 0.004). Although high-risk HPV was present in the majority of the lesions studied, the low frequency of HPV 16 (3.3%), low occurrence of cervical lesions and preserved immunological state in most of the HIV-positive patients were factors that may explain the low occurrence of precancerous cervical lesions in this population.

    With improved survival, more AIDS patients, especially heavy smokers and alcohol abusers, may be confronted with laryngeal squamous cell carcinoma. Since curative treatment may require aggressive combined therapy, these patients, often suffering from immunosupression and poor general condition, present unique therapeutic challenges. The objective of the study was to describe treatment dilemmas. This case report presents a detailed description of an AIDS patient with carcinoma of the larynx. A patient with T3N0M0 laryngeal carcinoma and AIDS underwent tracheotomy and biopsy, followed by severe neck and pulmonary infection. After convalescence, radiotherapy was administered, with no evidence of a disease during a 3.5-year follow-up. During his remaining life, the patient developed severe psychoaffective disorder, his immune state deteriorated until he demised from sepsis. In conclusion, patients with HIV infection, especially having a history of tobacco or alcohol abuse, should be carefully examined for head and neck carcinoma that is likely to be more aggressive. Following surgery, AIDS patients may have worse wound healing and a greater tendency to contract infections. Radiotherapy and especially chemotherapy may cause life-threatening complications. Although early detection may increase survival, curative treatment should involve many disciplines and extra caution.

    Sixty five patients with AIDS and clinical and/or radiological evidence of pulmonary infection underwent 78 bronchofibroscopies (BF) with protected brushing and bronchoalveolar washing-out. Out of the 78 BF, bacterial infection was diagnosed in 30 cases and associated opportunistic infection in 12 cases. The 18 cases of exclusively bacterial infection accounted for 23% of the total and most of them were due by H. influenzae and pneumococcus. Just in one patient, the thoracic radiography showed a localized infiltration. Given the high incidence of bacterial infections observed, along with the relevance of myxoid infections (opportunistic and pyogenic bacteria) and the low specificity of the thoracic radiography, bronchoalveolar washing-out and protected brushing in the same BF is a recommended practice.

    Acquired immunodeficiency syndrome (AIDS) was first reported in Brazil in 1980. In 1997, its incidence was 147 per million and then declined to 90 per million in 2000. Abnormalities of endocrine organ systems occur frequently in patients with AIDS. We evaluated mineralcorticoid, glucocorticoid, and thyroid hormone axes and glucose and insulin responses to a standardized oral glucose dose in healthy individuals; human immunodeficiency virus (HIV)-seropositive, asymptomatic individuals; HIV-infected patients with general lymphadenopathy, diarrhea, fever, fatigue, nocturnal sweating, and weight loss; and HIV-infected patients diagnosed with secondary infectious diseases or neoplasms. Baseline cortisol levels in the patients with AIDS were significantly higher than those in healthy control subjects. However, after adrenocorticotrophic hormone stimulation, cortisol levels were significantly lower in HIV-infected patients. Insulin concentrations were significantly higher after the glucose load in HIV-infected asymptomatic than in patients with AIDS. There were no significant differences in mineralocorticoid or thyroid function among groups.

We describe three infants, two with failure to thrive, who had dehydration and diarrhea within 1 month after their first or second rotavirus immunization and subsequently received a diagnosis of severe combined immunodeficiency. Rotavirus was detected, by means of reverse-transcriptase–polymerase-chain-reaction (RT-PCR) assay, in stool specimens obtained from all three infants, and gene-sequence analysis revealed the presence of vaccine rotavirus. These infections raise concerns regarding the safety of rotavirus vaccine in severely immunocompromised patients. PMID:20107217

    An outbreak of unexplained immune deficiency associated with opportunistic infection and Kaposi's sarcoma is occurring in the USA and other parts of the world. Affected individuals with what had come to be known as the acquired immune deficiency syndrome (AIDS) have a high mortality. Epidemiological features suggest the presence of a transmissable agent, but no responsible agent has yet been identified. Homosexual and bisexual men make up 75% of these affected individuals. Cytomegalovirus, Epstein Barr and herpes simplex viruses, organisms that commonly affect male homosexuals, may produce some features of AIDS. Individually or collectively, however, they can not account for the emergence of a previously unrecognized clinical syndrome. Hepatitis B is prevalent in patients with AIDS and may play a role as a co-factor in the disease. The properties of a number of other known viruses may provide a model for the pathogenesis of some features of the AIDS immunodeficiency. Newly described simian acquired immune deficiency syndrome (SAIDS) is the best available animal model. In man, the retrovirus, human T-cell leukemia virus (HTLV) may play a role in AIDS. However, HTLV or any other known virus cannot yet be assumed to cause AIDS. It is likely that an as yet unrecognized agent is the key causative agent of AIDS.

    The immunopharmacologic effects of Isoprinosine (INPX) have been associated with clinical benefit to the patient in a number of conditions characterized by immunodeficiency of diverse etiology. Immunodepressed homosexuals at risk of developing acquired immunodeficiency syndrome (AIDS) treated with placebo or INPX experienced an increase in the function and number of immunocompetent cells associated with clinical improvement. A multicenter trial designed to confirm these results has demonstrated that INPX produced an increase in natural killer (NK)-cell activity, total T cells, and T-helper cells, with certain effects persisting for months after completion of the 28-day treatment period. INPX-treated patients also experienced clinical improvement and decreased incidence of progression to AIDS. The administration of INPX for longer periods to patients with frank AIDS under a compassionate-use protocol has also proved useful. Clinical benefit associated with INPX treatment has been demonstrated in other patients with a depressed immune response, such as aged patients, cancer patients, severely burned patients, ill patients, and surgery patients. This program of clinical trials supports the therapeutic use of INPX in the treatment of AIDS and other acquired immunodeficiencies of clinical importance.

    Primary immunodeficiency diseases of the adult are rare disorders, but often lead to serious consequences. Therefore an early diagnosis is critical. The variety in the clinical presentation, the complexity of the immune system and the ongoing discovery of new defects render it a difficult area for the involved physician. Due to the often imprecise complaint of a weak immune system the primary task is the identification of patients with true immunodeficiency. Subsequently, the immune defect needs to be identified in collaboration with a center for immunodeficiency disorders. The diagnostic procedure is dependent on the pattern of infections and follows a defined series of steps. This procedure should prevent costly diagnostic evaluation when not indicated, and also prevent the delayed diagnosis of patients with manifest immunodeficiency disease.

    Horner's syndrome (HS) is related to an interruption of the oculosympathetic nerve pathway. The classic clinical findings associated with this condition are ptosis, miosis, and enophthalmos. Heterochromia is typically described in congenital HS, but it is an uncommon finding in acquired HS. We report a case of post-traumatic HS associated with heterochromia. A literature review indicates that this type of heterochromia may be related to a reduction in the number of iris melanocytes. This mechanism may be the same in the physiological iris color modifications in adulthood.

    Even in cases where viral replication has been controlled by antiretroviral therapy for long periods of time, human immunodeficiency virus (HIV)-infected patients have several non-acquired immunodeficiency syndrome (AIDS) related co-morbidities, including liver disease, cardiovascular disease and neurocognitive decline, which have a clear impact on survival. It has been considered that persistent innate and acquired immune activation contributes to the pathogenesis of these non-AIDS related diseases. Immune activation has been related with several conditions, remarkably with the bacterial translocation related with the intestinal barrier damage by the HIV or by hepatitis C virus (HCV)-related liver cirrhosis. Consequently, increased morbidity and mortality must be expected in HIV-HCV coinfected patients. Disrupted gut barrier lead to an increased passage of microbial products and to an activation of the mucosal immune system and secretion of inflammatory mediators, which in turn might increase barrier dysfunction. In the present review, the intestinal barrier structure, measures of intestinal barrier dysfunction and the modifications of them in HIV monoinfection and in HIV-HCV coinfection will be considered. Both pathogenesis and the consequences for the progression of liver disease secondary to gut microbial fragment leakage and immune activation will be assessed. PMID:26819512

    Background Intracranial vasculopathy in adult patients with human-acquired immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) is a rare but increasingly recognized disease entity. Objective We aimed to contribute to and summarize the adult literature describing patients with HIV/AIDS who have intracranial vasculopathy. Methods A retrospective review of adult patients with HIV/AIDS undergoing diagnostic cerebral angiography at our institution from 2007–2013 was performed. A literature review of relevant existing studies was performed. Results Five adult patients with HIV-related aneurysmal and occlusive vasculopathy were diagnosed and/or treated at our institution. A comprehensive review of the literature yielded data from 17 series describing 28 adult patients with HIV/AIDS and intracranial vasculopathy. Our review suggests that low CD4 count, motor weakness, and meningismus may be associated with the sequelae of intracranial vasculopathy/vasculitis in patients with HIV/AIDS. Conclusion Patients with HIV/AIDS who have aneurysmal and stenotic vascular disease may benefit from earlier surveillance with the onset of neurological symptoms. The roles of medical, open surgical, and endovascular therapy in this unique entity will be further defined as the pathological basis of the disease is better understood. PMID:26023074

    Acquired von Willebrand syndrome (aVWS) accounts for 22% of patients with abnormal von Willebrand factor. Most patients with known pathophysiological mechanisms suffer from cardiovascular, myeloproliferative and lymphoproliferative disorders. Less frequent associations are of autoimmune origin, due to hyperfibrinolysis, adsorption to tumor cells, reduced synthesis and prolonged circulation. The mechanisms leading to aVWS is hitherto not known in patients with liver and kidney diseases, drug use, glycogen storage disease, virus infections and at least 18 other disease entities. Diagnosis is complicated by the battery of tests needed, and their inherent rather low sensitivity and specificity for aVWS. Thus, even in acute bleeding situations it may take days until a firm diagnosis is settled and specific therapies can be initiated. The main aim is to shed more light onto this, compared with inherited von Willebrand disease, rare disease which affects at least 2-3% of the older population.

    According to the 15 autopsies performed at the Department of Pathological Anatomy, Escola Paulista de Medicina, São Paulo, Brazil, it was confirmed that acquired immunodeficiency syndrome (AIDS) occurs preferably in young homosexual males, who die in a short period of time of the disease, which leads to a consumptive state verified by cachexia of the cadavers. The most affected organs of this series were the lungs and encephalum, exactly the ones responsible for the immediate cause of death. In this series of autopsies there were 9 types of microorganisms represented by virus, bacteria, fungi, protozoans and two types of tumors, Kaposi's sarcoma and lymphoma of the central nervous system. From the microorganisms, the most frequent was the Cytomegalovirus and, from the tumors, Kaposi's sarcoma. The various types of microorganisms were frequently associated, principally in the central nervous and digestive systems. There was also association of microorganisms with tumors. Besides the lesions produced by microorganisms there were other associated alterations as brown atrophy of neuronia, which was related to the infiltration of cerebral lymphoma, and the lymphocytic depletion of lymphoid organs due to immunological exhaustion. Cellular reaction to microorganisms was practically none, principally with Pneumocystis carinii and Cryptococcus neoformans, the first one behaving as an inert mould in the pulmonary alveoli and the second proliferating freely in tissues. In two cases there was no granulomatous reaction to Mycobacterium tuberculosis. The primary lymphoma of the central nervous system should be interpreted as a microglioma, i.e., a reticulosarcoma of this system according to Hortega's school.

  7. Recapitulation of acquired immuno deficiency syndrome associated Kaposi's sarcoma

    Acquired immuno deficiency syndrome (AIDS) associated Kaposi's sarcoma (KS) is one of the clinical forms of KS. KS is caused by human herpes viruses 8 or KS associated herpes virus (KSHV). In India, till now, only 16 cases of AIDS associated KS was reported. Of all the clinical forms of KS, AIDS associated KS is distinct in many ways viz.; cutaneous manifestations commonly affects face and trunk rather than lower limbs, more mucosal lesions, rapidly progressive, and early systemic involvement. When human immunodeficiency virus (HIV) is co-infected with KSHV, in addition to the other pathogenic factors for the development of KS, HIV Tat protein promotes the proliferation of cytokine-activated endothelial cells and stimulates KS. Moreover, actions of HIV Tat lead to the aggressive course of KS in patients with AIDS, compared with the more confined behavior of KS in HIV-negative persons. Similarly, latency-associated nuclear antigen of KSHV would enhance HIV replication by activating the long terminal repeats of HIV-1 through its association with Tat. Effective antiretroviral treatment in AIDS associated KS results in reduction of the incidence of AIDS-related KS and regression of the existing lesions. Early diagnosis and treatment of AIDS associated KS would definitely increase the life span and quality of the patients. PMID:27890943

In addition, there have been few reports of T-cell defects in this condition, possibly because most of the reported patients have not been specifically evaluated for T-cell function. In this article, we present a child with an 11q deletion and combined immunodeficiency and we perform a literature overview on immunodeficiency in JS. Our patient presented with recurrent bacterial and prolonged viral infections involving the respiratory system, as well as other classic features of the syndrome. In addition to low IgM, IgG4, and B-cells, also low recent thymic emigrants, helper and naïve T-cells were found. We propose that patients with Jacobsen syndrome need thorough immunological evaluations as T-cell dysfunction might be more prevalent than previously reported. Patients with infections consistent with T-cell defects should be classified as having combined immunodeficiency. © 2016 Wiley Periodicals, Inc.

    The term 'organic brain syndrome' covers a multitude of ills, many of which are treatable conditions. Diagnosis must concentrate on defining which syndrome is involved; this article presents a diagnostic schema with illustrative case histories. Clinical aspects of acquired mental deficit are also outlined. The approach to organic brain syndromes is the classic medical observation of signs and symptoms. PMID:21297811

    To analyze the clinical features of AIDS-related Kaposi’s sarcoma (AIDS-KS) patients in Xinjiang Autonomous Region and the impact of CD4 +T lymphocyte count, highly active antiretroviral therapy (HAART) and systemic chemotherapy on the prognosis. The clinical information of 80 AIDS-KS patients admitted in Sixth People’s Hospital of Xinjiang Autonomous Region from January 2008 to August 2014 was retrospectively reviewed. Population characteristics, extent of lesions, KS progress, CD4 +T lymphocyte count, combined opportunistic infections, treatment and prognosis of these patients were analyzed. The 80 patients were divided into five groups according to treatment methods, including HAART, HAART + chemotherapy, chemotherapy + HAART, chemotherapy, and untreated groups. The efficacy and prognosis of the five groups were compared. Among the 80 patients, 74 (92.50%) patients were Uygur. The average age was 39.5±9.9 years and male-to-female ratio was 3:1. The median of baseline CD4 +T lymphocyte count was 152.5 cells/μL and the interquartile was 233.25 cells/μL. CD4 +T lymphocyte counts were significantly increased after treatment in HAART, HAART + chemotherapy, and chemotherapy + HAART groups (P < 0.05). CD4 +T lymphocyte count in chemotherapy groups was significantly reduced after treatment (P < 0.05). The untreated group had the highest mortality rate (33.3%). In HAART group, KS-associated immune reconstitution inflammatory response syndrome (KS-IRIS) appeared in 45.5% cases and 2 death cases were caused by KS-IRIS. In Xinjiang Autonomous Region, the incidence of AIDS-KS is high in young Uygur male people. HAART followed by chemotherapy has ideal efficacy, reduces the incidence of KS-IRIS and improves the prognosis. PMID:26770484

    It is commonly accepted that the presence of high amounts of maternal T cells excludes Omenn syndrome (OS) in severe combined immunodeficiency (SCID). We report a SCID patient with a novel mutation in the recombination activating gene (RAG)1 gene (4-BP DEL.1406 TTGC) who presented with immunodeficiency and OS. Several assays, including representatives of specific T cell receptors (TCR), Vβ families and TCR-γ rearrangements, were performed in order to understand more clearly the nature and origin of the patient's T cells. The patient had oligoclonal T cells which, based on the patient–mother human leucocyte antigen (HLA)-B50 mismatch, were either autologous or of maternal origin. These cell populations were different in their numbers of regulatory T cells (Treg) and the diversity of TCR repertoires. This is the first description of the co-existence of large amounts of clonal expanded autologous and transplacental-acquired maternal T cells in RAG1-deficient SCID. PMID:24666246

    An in vitro coculture model system of CD34+ stem cells and allogenic cultured thymic epithelia fragments was used to evaluate thymocyte differentiation in a 9-month-old child of Amish descent with Nezelof syndrome. Though the patient`s stem cells differentiate to acquire normal expression of CD2 and CD7, later steps of maturation were abnormal. There was detectable but reduced expression of CD3 and CD4 phenotypes. CD44+ expression, however, was markedly reduced. CD44 is an adhesion molecule, interacting with the matrix ligands hyaluronan and fibronectin, and is expressed early in thymocyte differentiation and subsequently in mature T cells. It is hypothesized that abnormal expression of CD44 in a variant of severe combined immunodeficiency, Nezelof`s syndrome, interferes with normal thymocyte and thymic epithelial interaction, which leads to abnormal thymocyte differentiation. 35 refs., 2 figs., 3 tabs.

    Eighty-percent of 47 parenteral drug abusers with hepatomegaly and acquired immunodeficiency syndrome had HBV DNA in serum, although only 27% were HBsAg or "e" antigen-positive by polyclonal radioimmunoassay. Liver biopsies from each of 37 HBV DNA seropositive patients showed HBV DNA and were HBcAg-positive. The absence of positive HBsAg and "e" antigen in HBV DNA-positive patients was attributable to the presence of immune complexes; after in vitro dissociation of these complexes there was an increase in HBsAg from 24% to 86%, and of "e" antigen from 19% to 62%. These data indicate that actively replicating hepatitis B virus is common in patients with AIDS, and that precautions should be taken to prevent its dissemination. Therapy in these patients should address both human immunodeficiency and hepatitis B virus infections.

    Six patients with the acquired immune deficiency syndrome (AIDS) had exacerbations or recurrences of previously quiescent atopic disease when they developed immunodeficiency. Four developed a different atopic illness from that suffered previously. Atopic symptoms developed within three months after the patients developed AIDS or during prodromal illness. Two of the patients were treated with recombinant interferon gamma: both showed a striking improvement in symptoms and cellular immunity. These results indicate that cellular immunity, through interferon gamma, may have a role in regulating atopic disease. PMID:3109572

    India has a large number of patients with acquired immune deficiency syndrome (AIDS), the third largest population of this group in the world. This disease was first described in patients with Pneumocystis pneumonia in 1981. Ocular lesions can occur at any stage of the disease but are more commonly seen at the late stages. Human immunodeficiency virus (HIV), the causative agent of AIDS is a retrovirus with RNA genome and a unique 'Reverse transcriptase enzyme' and is of two types, HIV-1 and 2. Most human diseases are caused by HIV-1. The HIV-1 subtypes prevalent in India are A, B and C. They act predominantly by reducing the CD4+ cells and thus the patient becomes susceptible to opportunistic infections. High viral titers in the peripheral blood during primary infection lead to decrease in the number of CD4+ T lymphocytes. Onset of HIV-1-specific cellular immune response with synthesis of HIV-1 specific antibodies leads to the decline of plasma viral load and chronification of HIV-1 infection. However, the asymptomatic stage of infection may lead to persistent viral replication and a rapid turnover of plasma virions which is the clinical latency. During this period, there is further decrease in the CD4+ counts which makes the patient's immune system incapable of controlling opportunistic pathogens and thus life-threatening AIDS-defining diseases emerge. Advent of highly active antiretroviral treatment (HAART) has revolutionized the management of AIDS though there is associated increased development of immune recovery uveitis in a few of these patients.

    One out of three pediatric sepsis deaths in high income countries occur in previously healthy children. Primary immunodeficiencies (PIDs) have been postulated to underlie fulminant sepsis, but this concept remains to be confirmed in clinical practice. Pseudomonas aeruginosa (P. aeruginosa) is a common bacterium mostly associated with health care-related infections in immunocompromised individuals. However, in rare cases, it can cause sepsis in previously healthy children. We used exome sequencing and bioinformatic analysis to systematically search for genetic factors underpinning severe P. aeruginosa infection in the pediatric population. We collected blood samples from 11 previously healthy children, with no family history of immunodeficiency, who presented with severe sepsis due to community-acquired P. aeruginosa bacteremia. Genomic DNA was extracted from blood or tissue samples obtained intravitam or postmortem. We obtained high-coverage exome sequencing data and searched for rare loss-of-function variants. After rigorous filtrations, 12 potentially causal variants were identified. Two out of eight (25%) fatal cases were found to carry novel pathogenic variants in PID genes, including BTK and DNMT3B. This study demonstrates that exome sequencing allows to identify rare, deleterious human genetic variants responsible for fulminant sepsis in apparently healthy children. Diagnosing PIDs in such patients is of high relevance to survivors and affected families. We propose that unusually severe and fatal sepsis cases in previously healthy children should be considered for exome/genome sequencing to search for underlying PIDs.

    Malignant atrophic papulosis is a rare disorder characterized by pathognomonic cutaneous lesions that consist of infarctive thrombosis. Visceral involvement often occurs; the gastrointestinal tract and the central nervous system are most frequently involved. Malignant atrophic papulosis has not been previously described in an AIDS patient. We describe a 58-year-old homosexual man with AIDS who developed typical cutaneous lesions of malignant atrophic papulosis. No visceral involvement has been detected in 2 years.

    A twenty nine year old male homosexual presented with malaise, weight loss, fever and profuse sweating. An ill defined abdominal mass was found during physical examination in the right lower quadrant and chest X rays disclosed a pleural effusion. HIV antibodies and hepatitis B surface antigen were positive and immunological parameters were altered. Light and electron microscopic examination of operative biopsies of the abdominal mass revealed the presence of Histoplasma capsulatum. Treatment with Amphotericin B was started with a favorable response and the patient was discharged. He was readmitted with a septic shock and died. Necropsy showed pulmonary histoplasmosis. This is the first case of disseminated histoplasmosis in a patient with AIDS described in Chile.

    The role of nutrition in the management of HIV infection and AIDS is now widely recognized. To highlight the influence of nutrition on the progress of HIV/AIDS and the role and importance of good nutrition in the management of the disease, literature selected from local and international scientific books and journals on the subject of nutrition and HIV/AIDS were reviewed and synthesized in this article. As an intervention, it should begin in the early stages of HIV infection and should include nutrition counseling, and in the later stages of the disease, using more advanced nutrition support methods including enteral and parenteral support. These would enable HIV/AIDS patients to achieve an adequate nutrient intake and energy for as long as possible, thus enhancing the quality of their lives and minimizing the symptoms of the disease.

    Herpes simplex (HSV) infection of the central nervous system is uncommon in AIDS and usually has an atypical topography. This review is centred around the case of a 49-year-old homosexual patient with AIDS who died from diffuse encephalopathy. Neuropathological examination revealed necrotic and haemorrhagic changes involving both temporal lobes, insulae and cingulate gyri. Cowdry type A intranuclear inclusion bodies were abundant but inflammation was minimal. Electron microscopy confirmed characteristic herpes virus particles. Immunocyto-chemistry was positive for HSV type 1 and 2. In situ hybridization and PCR, however, were positive for HSV type 1 but excluded HSV type 2. There was associated cytomegalovirus ventriculitis but clearly separated from HSV encephalitis. There were no histological features of HIV encephalitis and HIV could not be demonstrated by immunocytochemistry or by PCR to demonstrate proviral DNA. Apoptotic neurons were numerous in areas with a severe macrophage reaction. Only two pathological cases with characteristic limbic distribution and necrotic haemorrhagic histologic have been reported previously. The rarity of these reports suggests that in advanced AIDS, the immune reaction causing a typical necrotizing encephalitis cannot be mounted. Distinction between HSV type 1 and 2 infection may be difficult by immunocytochemistry and usually requires in situ hybridization, tissue culture or PCR. In AIDS patients, HSV-1 has been identified as responsible for encephalitis whereas HSV-2 has been more responsible for myelitis. Associated productive HIV infection of the CNS was found in none of the cases. In contrast, cytomegalovirus encephalitis was found in nine of 11 cases of AIDS-associated HSV encephalitis.

    A 47-year-old male with acquired immune deficiency syndrome (AIDS) presented with multiple hyperpigmented papules and nodules on both ankles, dorsum of bilateral feet and soles. It was associated with mild itching and pain. The patient was diagnosed with human immunodeficiency virus (HIV) in 2007. First-line antiretroviral therapy (ART) was started in 2009 to which he responded initially. He was shifted to second-line ART 11 months ago in March 2015 due to treatment failure as suggested by CD4 count of 50 cells/mm3. The present skin lesions started 2 months after the initiation of second-line ART. Differential diagnoses considered were Kaposi's sarcoma and immune reconstitution inflammatory syndrome (IRIS) related infections, but biopsy was suggestive of erythema elevatum diutinum (EED). Patient was started on oral dapsone 100 mg/day and increased to 200 mg/day to which he is responding gradually. In the present case, appearance of the lesions after initiation of second-line ART coupled with increase in CD4 count and decrease of viral load below undetectable level suggest that EED could be an IRIS.

    Several immune mechanisms are suspected in the unknown etiology of West syndrome (WS). We report a male infant who suffered from WS and X-linked T-B+NK- severe combined immunodeficiency (X-SCID) with a missense mutation of the IL2RG gene (c.202G>A, p.Glu68Lys). He promptly began vitamin B6 and valproic acid treatment, but infantile spasms (IS) and hypsarrhythmia persisted. Administration of intravenous immunoglobulin and the change to topiramate (TPM) at 7 months of age resulted in the rapid resolution of IS. The CD4/8 ratio in his peripheral blood increased from 0.04-0.09 to 0.20-1.95 following unrelated cord blood transplantation (UCBT). In vitro lymphocyte proliferation in response to phytohemagglutinin or concanavalin A and the ability of B lymphocytes to produce antibodies improved as well. Electroencephalogram findings became normal 1 month after UCBT. Thus, we consider that T-cell dysfunction and/or impairments in T-B cell interactions due to X-SCID may have played important roles in the onset of WS. Immune-modulating therapies along with the administration of TPM effectively treated this severe epileptic syndrome in our patient.

    A 2-year-old boy, having undergone fundoplication for gastroesophageal reflux disease and fed by gastrostomy, presented with recurrent emesis, syncope with hypoglycemia, and persistently elevated serum liver transaminase levels. Liver biopsy revealed hepatocellular glycogenosis by light and electron microscopy. Further evaluation showed no evidence of diabetes mellitus, glycogen storage disease, or corticosteroid use. Since the hyperglycemic-hyperinsulinemic state of dumping syndrome would provide a mechanism for hepatocellular glycogenosis, the biopsy findings prompted consideration of dumping syndrome. Metabolic evaluation confirmed the diagnosis of dumping syndrome, and appropriate dietary management led to sustained resolution of symptomatology and hypertransaminasemia. Dumping syndrome is proposed to be a cause of hepatocellular glycogenosis, the latter representing a form of acquired glycogenic hepatopathy.

There are subtle but important differences between these conditions that are important to recognize for prognostic and therapeutic purposes. This article provides a clinicopathologic update on how understanding of these B-cell lymphoproliferations in immunodeficiency has evolved over the past decade.

    Unified procedures to control those infections that are transmitted by inoculation of blood are recommended. These should be applied to patients with acquired immune-deficiency syndrome (AIDS), AIDS-related complex, persistent generalized lymphadenopathy or hepatitis B, those with serological evidence of infection by human immunodeficiency virus or hepatitis B virus, and those in medical and social categories with a higher than average prevalence of such infections. When the identification of these categories of patient would be particularly difficult, the precautions should be applied to all patients, in situations of high risk for inoculation incidents. Rational infection-control measures, based on the known mode of spread, permit efficient management of infected patients, with satisfactory protection of staff and other patients.

    An atypical lymphoproliferative process occurred in the liver and spleen of a child with combined immunodeficiency disease and polyglandular failure syndrome. The initial pathologic interpretation was that of malignant lymphoma, although the child's subsequent clinical course was complicated by rheumatoid arthritis, thyroiditis, and chronic active hepatitis, with no clear evidence of lymphoid neoplasia. This case illustrates that unusual lymphoid proliferations in patients with immunodeficiencies may simulate malignant lymphoma.

    The congenital immunodeficiency disorders in which the defect has been clearly traced to the stem cell can be cured with allogeneic stem-cell transplantation (SCT) from an unaffected donor. Widespread application of this treatment modality has been tempered by the fact that risk-benefit considerations do not always favor a procedure that carries a significant risk for morbidity and mortality. Some malignant disorders of childhood eventually have to be treated by an autologous or allogeneic SCT, however nonmalignant disorders can also be treated with this approach. This article reviews the current status of SCT for nonmalignant inherited immunodeficiency disorders.

To date, there have been limited reports of IRIS in the central nervous system (CNS). Here, the authors describe a 43-year-old man with AIDS who presented with subacute meningitis. No pathogenic organism was identified by routine diagnostic tests, and he was treated empirically with an antituberculous regimen and initiated on HAART therapy. Soon after, he had a precipitous neurologic decline leading to his death. Postmortem evaluation showed a basilar Candida meningitis as well as vasculitis characterized by CD8+ T-cell infiltration, consistent with IRIS. The authors discuss the challenges in diagnosing fungal meningitides and the risks of initiating HAART therapy in those with possible undiagnosed underlying opportunistic infections. Additionally, the authors review the literature regarding CNS IRIS.

    Primary immunodeficiencies (PIDs) are uncommon, chronic and severe disorders of the immune system in which patients cannot mount a sufficiently protective immune response, leading to an increased susceptibility to infections. The treatment of choice for PID patients with predominant antibody deficiency is intravenous immunoglobulin (Ig) replacement therapy. Despite major advances over the last 20 years in the molecular characterization of PIDs, many patients remain undiagnosed or are diagnosed too late, with severe consequences. Various strategies to ensure timely diagnosis of PIDs are in place, and novel approaches are being developed. In recent years, several patient registries have been established. Such registries shed light on the pathology and natural history of these varied disorders. Analyses of the registry data may also reveal which patients are likely to respond well to higher Ig infusion rates and may help to determine the optimal dosing of Ig products. Faster infusion rates may lead to improved convenience for patients and thus increase patient compliance, and may reduce nursing time and the need for hospital resources. Data from two recent studies suggest that Gamunex® and Privigen® are well tolerated at high infusion rates. Nevertheless, careful selection of patients for high infusion rates, based on co-morbid conditions and tolerance of the current infusion rate, is advisable. Based on the available data, intravenous Ig offers broad protection against encapsulated organisms. As vaccine trends change, careful monitoring of specific antibody levels in the general population, such as those against pneumococcal and meningococcal bacteria, should be implemented.

    The mitogenic activity of the formalin-treated bacterial strains Branhamella catarrhalis, Haemophilus influenzae and the Cowan I strain of Staphylococcus aureus was assessed in peripheral blood lymphocytes (PBL) from patients with primary immunodeficiencies, acute lymphocytic leukaemia (ALL), chronic lymphocytic leukemia (CLL) and in umbilical cord blood lymphocytes. The bacteria selectively stimulated B cells, as demonstrated by the finding of a normal de novo DNA synthesis in children with a T cell defect and of an absent response in X-linked agammaglobulinaemia and severe combined immunodeficiency. A decreased mitogenic activity was exerted on PBL from four out of seven adults with common variable hypogammaglobulinemia (CVH). In B-CLL the mitogenic activity was normal while in T-ALL it was decreased. Umbilical cord blood lymphocytes responded better than PBL from adults. The selective stimulative ability of the bacteria for B lymphocytes is expressed when PBL are cultured together with the formalin-treated bacteria for 48 to 72 hr. PMID:6976247

    The commonest association of thymic stromal deficiency resulting in T-cell immunodeficiency is the DiGeorge syndrome (DGS). This results from abnormal development of the third and fourth pharyngeal arches and is most commonly associated with a microdeletion at chromosome 22q11 though other genetic and non-genetic causes have been described. The immunological competence of affected individuals is highly variable, ranging from normal to a severe combined immunodeficiency when there is complete athymia. In the most severe group, correction of the immunodeficiency can be achieved using thymus allografts which can support thymopoiesis even in the absence of donor-recipient matching at the major histocompatibility loci. This review focuses on the causes of DGS, the immunological features of the disorder, and the approaches to correction of the immunodeficiency including the use of thymus transplantation.

    In the pediatric population, intracranial fusiform aneurysms have been associated with human immunodeficiency virus/acquired immunodeficiency syndrome and rarely with opportunistic infections related to other immunodeficiencies. The HIV virus and other infectious organisms have been implicated in the pathophysiology of these aneurysms. We present a child with T-cell immunodeficiency but no evidence of human immunodeficiency virus or opportunistic intracranial infections that developed progressive bilateral fusiform intracranial aneurysms. Our findings suggest a role of immunodeficiency or inflammation in the formation of some intracranial aneurysms.

    In the past decade, the availability of powerful molecular techniques has accelerated the pace of discovery of several new primary immunodeficiencies (PID) and revealed the biologic basis of other established PID. These genetic advances, in turn, have facilitated more precise phenotyping of associated skin and systemic manifestations and provide a unique opportunity to better understand the complex human immunologic response. These continuing medical education articles will provide an update of recent advances about PID that may be encountered by dermatologists through their association with eczematous dermatitis, infectious, and non-infectious cutaneous manifestations. Part I will discuss new primary immunodeficiencies that have an eczematous dermatitis. Part II will focus on primary immunodeficiencies that greatly increase susceptibility to fungal infection and the noninfectious presentations of PID. PMID:26282794

    Hemophagocytic lymphohistiocytosis is a hyperinflammatory syndrome defined by clinical and laboratory criteria. Current criteria were created to identify patients with familial hemophagocytic lmyphohistiocytosis in immediate need of immunosuppressive therapy. However, these criteria also identify patients with infection-associated hemophagocytic inflammatory states lacking genetic defects typically predisposing to hemophagocytic lymphohistiocytosis. These patients include those with primary immunodeficiencies, in whom the pathogenesis of the inflammatory syndrome may be distinctive and aggressive immunosuppression is contraindicated. To better characterize hemophagocytic inflammation associated with immunodeficiencies, we combined an international survey with a literature search and identified 63 patients with primary immunodeficiencies other than cytotoxicity defects or X-linked lymphoproliferative disorders, presenting with conditions fulfilling current criteria for hemophagocytic lymphohistiocytosis. Twelve patients had severe combined immunodeficiency with <100/μL T cells, 18 had partial T-cell deficiencies; episodes of hemophagocytic lymphohistiocytosis were mostly associated with viral infections. Twenty-two patients had chronic granulomatous disease with hemophagocytic episodes mainly associated with bacterial infections. Compared to patients with cytotoxicity defects, patients with T-cell deficiencies had lower levels of soluble CD25 and higher ferritin concentrations. Other criteria for hemophagocytoc lymphohistiocytosis were not discriminative.

    Brown syndrome is known as limited elevation of the affected eye during adduction. It is caused by a disorder of the superior oblique tendon, which makes it difficult for the eyeball to look upward, especially during adduction. It is classified into congenital true sheath Brown syndrome and acquired simulated Brown syndrome. Acquired simulated Brown syndrome can be caused by trauma, infection, or inflammatory conditions. The surgical restoration of blowout fractures can also lead to limitations of ocular motility, including Brown syndrome. We report on three patients with acquired simulated Brown syndrome, who complained of diplopia and limitation of ocular motility after operations to treat blowout fractures. PMID:26015892

    The acquired immune deficiency syndrome (AIDS) is a devastating new illness which appears to be sexually and parenterally transmissible. AIDS was first described in the male homosexual community; however, the disease has more recently been described among intravenous drug abusers, Haitians, hemophiliacs, and others. The etiologic agent is unknown. AIDS may represent an infection by a previously undescribed organism, a mutant of a known microorganism, or a multifactorial combination of environmental, immunologic, and genetic factors. As a consequence of the disease's seemingly irreversible ablation of the cell-mediated immune system, AIDS victims succumb to a variety of infections and/or unusual neoplasms. In its fully developed form, mortality approaches 100%. At autopsy the gross and microscopic pathology of the syndrome can be divided into three general categories: 1) morphologic manifestations of profound lymphoid depletion; 2) infections, usually with mixed opportunistic pathogens; and 3) unusual neoplasms, most frequently Kaposi's sarcoma or high-grade lymphomas.

    The spread of human immunodeficiency virus (HIV) infection within Africa led to marked increases in numbers of cases of tuberculosis (TB), and although the epidemic peaked in 2006, there were still 1.8 million new cases in 2013, with 29.2 million prevalent cases. Half of all TB cases in Africa are in those with HIV co-infection. A brief review of the well-documented main immunological mechanisms of HIV-associated increased susceptibility to TB is presented. However, a new threat is facing TB control, which presents itself in the form of a rapid increase in the number of people living with type II diabetes mellitus (T2DM), particularly in areas that are already hardest hit by the TB epidemic. T2DM increases susceptibility to TB threefold, and the TB burden attributable to T2DM is 15%. This review addresses the much smaller body of research information available on T2DM-TB, compared to HIV-TB comorbidity. We discuss the altered clinical presentation of TB in the context of T2DM comorbidity, changes in innate and adaptive immune responses, including lymphocyte subsets and T-cell phenotypes, the effect of treatment of the different comorbidities, changes in biomarker expression and genetic predisposition to the respective morbidities, and other factors affecting the comorbidity. Although significant gains have been made in improving our understanding of the underlying mechanisms of T2DM-associated increased susceptibility, knowledge gaps still exist that require urgent attention.

    Cutaneous granulomas with prominent caseating necrosis are a rare manifestation of immunodeficiency. Extensive and recalcitrant cutaneous viral infections can also be seen. We present a case of an 18-year-old white man with an early onset poorly characterized combined immunodeficiency syndrome who, over the past 5 years, developed enlarging tender red-purple plaques on his extremities and pink near-confluent macules on his chest and back. Previous biopsies of the red-purple plaques showed features of granuloma annulare. Histopathological examination of old and new biopsies revealed both sarcoidal and palisading necrobiotic granulomas with perforating features and elastophagocytosis. Stains and tissue cultures were negative for bacterial and fungal organisms. In addition, biopsy of a macule on the back demonstrated verruca plana with characteristics of epidermodysplasia verruciformis. As an infant, the patient had failure to thrive and a combined immunodeficiency, but was lost to follow-up for 15 years. He currently continues to have severe hypogammaglobinemia and cellular immunodeficiency. Intravenous immunoglobulin and prednisone were initiated and his plaques improved rapidly. Topical imiquimod was ineffective for the verruca plana. The patient and his parents are currently undergoing whole exome sequencing including evaluation for epidermodysplasia verruciformis 1 and 2 gene mutations. This case highlights the importance of including genetic immunodeficiency disorders in the clinical and histopathological differential diagnosis for cutaneous sarcoidal or palisading necrobiotic granulomas and for extensive cutaneous viral infection.

    An increase of sexually transmitted shigellosis is currently being reported in developed countries. In addition, travel-related shigellosis can introduce resistant strains that could be disseminated within this new scenario. Epidemiological features and antimicrobial susceptibility of shigellosis depending on where infection was acquired were investigated. From 2008 to 2013, subjects with shigellosis were studied. Patients were classified according to acquisition of Shigella as traveler's diarrhea (TD) or domestically acquired diarrhea (DAD). Ninety cases of shigellosis were identified: 76 corresponding to the TD group and 14 to the DAD group. In the DAD group, most of patients were human immunodeficiency virus (HIV)-positive men who have sex with men (MSM), being shigellosis associated to male sex (P = 0.007) and HIV infection (P < 0.0001). S. sonnei (47.8%) and S. flexneri (42.2%) were the predominant species. The highest resistance was detected for trimethoprim/sulfamethoxazole (SXT) (81.8%), followed by ampicillin (AMP) (37.8%) and ciprofloxacin (CIP) (23.3%). Resistant Shigella strains were more frequent in subjects with TD than those with DAD, although only for CIP the difference was significant (P = 0.034). Continuous monitoring of patients with shigellosis is necessary to control the spread of resistant Shigella strains and for effective therapy. Men with shigellosis who have not traveled to an endemic area should be screened for HIV infection. PMID:26195465

    Diarrhea is one of the most common symptoms in common variable immunodeficiency, but neurologic manifestations are rare. We presented a 50-year-old woman with recurrent diarrhea and severe weight loss that developed a posterior cord syndrome. Endoscopy found a duodenal villous blunting, intraepithelial lymphocytosis, and lack of plasma cells and magnetic resonance imaging of the spine was normal. Laboratory assays confirmed common variable immunodeficiency syndrome and showed low levels of trace elements (copper and zinc). Treatment was initiated with parenteral replacement of trace elements and intravenous human immunoglobulin and the patient improved clinically. In conclusion, physicians must be aware that gastrointestinal and neurologic disorders may be related to each other and remember to request trace elements laboratory assessment. PMID:28356913

    A 37-year-old man, a hepatitis B virus carrier due to mother-to-child transmission, had a medical examination in September 2008 in nearby hospitals due to anorexia and weight loss. He was transported to our hospital because computed tomography (CT) detected intracranial lesions, and he had a positive human immunodeficiency virus (HIV) antibody test. Head computed tomography (CT) revealed multiple hemorrhagic lesions and enhancement effect, suggesting a thin wall. Also, an enhancement effect was present in the ventricle walls and the subarachnoid space. No accumulation was found in the thallium-201 scintigraphy. The enhancement effect of the ventricle walls and the subarachnoid space disappeared after oral administration of pyrimethamine, sulfadiazine, and calcium folinate, contributing to the diagnosis of an abscess and meningitis due to toxoplasma. However, mass lesions did not reduce. A biopsy was performed on 30 October, and the pathological diagnosis was malignant lymphoma. He died from respiratory function deterioration on 8 November. Lymphoma cells were found in ventricle wall tissue and the subarachnoid space at the autopsy. Toxoplasmosis will typically occur as a brain lesion most commonly in acquired immune deficiency syndrome (AIDS), whereas malignant lymphoma commonly manifests as a brain neoplastic lesion. However, differentiating between images of these lesions is difficult, so diagnosis by early biopsy is recommended.

    The Acquired Immune Deficiency Syndrome (AIDS) is a new disease which first appeared in human populations about 1979. The disease is defined by the development of unusual types of cancer (e.g. Kaposi's sarcoma), or severe cellular immunodeficiency manifested by opportunistic infections (e.g. Pneumocystis carinii infection), or both. Although the etiology of AIDS is unknown, the epidemiologic evidence is consistent with an infectious agent transmitted by blood (e.g. transfusion, needle sharing) or sexual intercourse. Over three-quarters of the cases have been in homosexual or bisexual males and in intravenous drug abusers; about 5% of cases do not have recognized risk factors. A small number of cases have resulted from transfusion of blood or blood products. The early clinical manifestations are non-specific, and may include asymptomatic skin lesions, dyspnea and dry cough, weight loss, chronic diarrhea, and focal and non-focal central nervous system findings. Treatment for the associated cancers and opportunistic infections may be successful in individual instances, but the underlying immunosuppression of AIDS appears to progress inexorably and the fatality rate approaches 100% within a few years from diagnosis. Although nosocomial transmission has not been documented, infection control guidelines have been developed by analogy with hepatitis B infection.

    Substantial progress has been made in China in using traditional Chinese medicine (TCM) to treat acquired immune deficiency syndrome (AIDS). Our objective was to review the latest developments in TCM treatment of AIDS in China between 2004 and 2014. We reviewed the content of original articles investigating the efficacy and safety of TCM for treating AIDS published in Chinese and English language journals. Relevant references from 2004 to 2014 were found using PubMed and the China National Knowledge Infrastructure Database. We found that TCM has been widely used for treating AIDS and its complications in China. The number of TCM studies has increased, which indicates efficacy and safety. Measures of efficacy in the reviewed articles included the alleviation of human immunodeficiency virus (HIV)-related signs and symptoms, improvements in quality of life, improvements in long-term survival, counteraction of the adverse side effects of antiviral drugs, promotion of immune reconstitution, and improvement of laboratory results. In sum, the literature indicates that TCM is safe. TCM plays an important role in the treatment of AIDS. Some studies have attempted to measure the efficacy and safety of TCM for treating AIDS, but more evidence is needed. Therefore, more research on this topic is required in the future.

    By the age of two years, almost all infants are infected with the Respiratory syncytial virus (RSV). One of the main causes of hospitalizations for bronchiolitis and pneumonia at this age is RSV infection. In addition to well-known risks for severe RSV disease, such as prematurity, bronchopulmonary dysplasia and congenital heart disease, immunodeficiencies, chromosomal abnormalities such as Down's syndrome or neuromuscular diseases have also been identified as risks. While the medical needs for RSV prevention in these risk groups are high, clinical evidence to support this is limited. Palivizumab was recently approved in Japan for prophylaxis in children with immunodeficiency or Down's syndrome. A clinical guidance protocol for the prevention of RSV infection using Palivizumab in these risk groups is provided here on the basis of a review of the available literature and on expert opinion. Thus, the present article reviews the published literature related to RSV infections in infants and children with immunodeficiencies or Down's syndrome in order to outline the risks, pathology and physiology of severe RSV disease in these patient groups. The purpose of this article is to facilitate understanding of the medical scientific bases for the clinical guidance.

    Prominent neck extension weakness is an uncommon clinical entity, also termed dropped-head syndrome, that may be part of a generalized neuromuscular disorder. We report here the case of a woman with dropped-head syndrome and pulmonary arterial hypertension secondary to systemic sclerosis. Subsequently, she developed common variable immunodeficiency and subcutaneous immunoglobulin therapy was started. After two months from the start of therapy we did not observe any improvement in the degree of flexion of the head, although the clinical examination shows an improvement in neck extensor muscle strength. Subcutaneous immunoglobulin therapy could be a possible therapeutic option for the treatment of myopathic neck extensor weakness.

    Objective: To investigate the clinical and epidemiologic features of pediatric acquired demyelinating syndromes (ADS) of the CNS in Japan. Methods: We conducted a nationwide survey and collected clinical data on children with ADS aged 15 years or younger, who visited hospitals between 2005 and 2007. Results: Among 977 hospitals enrolled, 723 (74.0%) responded to our inquiries and reported a total of 439 patients as follows: 244 with acute disseminated encephalomyelitis (ADEM), 117 with multiple sclerosis (MS), 14 with neuromyelitis optica (NMO), and 64 with other ADS. We collected and analyzed detailed data from 204 cases, including those with ADEM (66), MS (58), and NMO (10). We observed the following: (1) the estimated annual incidence rate of pediatric ADEM in Japan was 0.40 per 100,000 children (95% confidence interval [CI], 0.34–0.46), with the lowest prevalence in the north; (2) the estimated prevalence rate of MS was 0.69 per 100,000 children (95% CI, 0.58–0.80), with the lowest prevalence in the south; (3) NMO in Japan was rare, with an estimated prevalence of 0.06 per 100,000 children (95% CI, 0.04–0.08); and (4) the sex ratio and mean age at onset varied by ADS type, and (5) male/female ratios correlated with ages at onset in each ADS group. Conclusions: Our results clarify the characteristic clinical features of pediatric ADS in the Japanese population. PMID:27742816

    Acquired immune-deficiency syndrome (AIDS) is becoming an increasing problem to the surgeon. The impact of HIV/AIDS on surgical practice include the undoubted risk to which the surgeon will expose him or herself, the atypical conditions that may be encountered and the outcome and long term benefit of the surgical treatment in view of disease progression. The two factors most associated with surgical outcome and poor wound healing were AIDS and poor performance status (ASA score). This article questions whether gastrointestinal surgical procedures can be safe and effective therapeutic measures in HIV/AIDS patients and if surgical outcome is worthy of the surgeon's ethical responsibility to treat. As HIV/AIDS patients are not a homogeneous group, with careful patient selection, emergency laparotomy for peritonitis confers worthwhile palliation. However, aggressive surgical intervention must be undertaken with caution and adequate peri-operative care is required. Symptomatic improvement of anorectal pathology may make delayed wound healing an acceptable complication. Alternatives to surgery can be contemplated for diagnosis, prophylaxis or palliation.

This article focuses on the most common hematologic disorders associated with human immunodeficiency virus infection and acquired immunodeficiency syndrome, which can precipitate complications and frequently accompany hospitalization. It is important for nurses to have a solid foundation as to the cause of these disorders, their impact on quality of life and outcomes, and management strategies.

    Instability of the heterochromatic centromeric regions of chromosomes 1, 9, and 16 associated with immunodeficiency was found in a four year old girl. Similar phenotypic and chromosomal abnormalities were described in a previous patient studied by us and in four other published cases. All these patients have facial anomalies in addition to combined immunodeficiency and chromosomal instability. Stretching of the heterochromatic centromeric regions of chromosomes 1, 16, and to a lesser extent, 9 and homologous and non-homologous associations of these regions were the most common cytogenetic findings in all the patients. Multi-branched configurations and whole arm deletions of chromosomes 1 or 16 or both were also found. Comparing clinical and chromosomal data we conclude that immunodeficiency, centromeric heterochromatin instability, and facial anomalies form a new syndrome, for which we propose the acronym ICF. A mutation interfering with the normal process of condensation of part of the centromeric heterochromatin is postulated as the basic chromosome defect in this syndrome. Images PMID:3351904

    Patients with the acquired immune deficiency syndrome (AIDS) frequently develop hepatic dysfunction. Although hepatic injury may indirectly result from malnutrition, hypotension, administered medications, sepsis, or other conditions, the hepatic injury is frequently due to opportunistic hepatic infection, directly related to AIDS. Infection with Mycobacterium avium intracellulare typically occurs in patients with advanced immunocompromise and with systemic symptoms due to widely disseminated infection. In contrast, hepatic tuberculosis often occurs with less advanced immunocompromise. Cytomegaloviral infection may produce a hepatitis. Cytomegaloviral and cryptosporidial infections have been implicated as causes of acalculous cholecystitis and of a secondary sclerosing cholangitis. About 10-20% of patients with AIDS have chronic hepatitis B infection. These patients tend to develop minimal hepatic inflammation and necrosis. The clinical findings in patients with hepatic cryptococcal infection are usually due to concomitant extrahepatic infection. Hepatic histoplasmosis usually develops as part of a widely disseminated infection with systemic symptoms. Hepatic involvement by Kaposi's sarcoma is rarely documented ante mortem because an unguided liver biopsy is an insensitive diagnostic procedure. Patients with non-Hodgkin's lymphoma of the liver typically have lymphadenopathy, hepatomegaly, and systemic symptoms. As a pragmatic approach, patients with liver dysfunction and HIV-related disease should have a sonographic or computerized tomographic examination of the liver. Patients with dilated bile ducts should undergo endoscopic retrograde cholangiopancreatography because opportunistic infection may produce biliary obstruction. Patients with a focal hepatic lesion should be considered for a guided liver biopsy. Patients with a significantly elevated serum alkaline phosphatase level should be considered for a percutaneous liver biopsy. When performed for these

    The ineffective immune response in patients with the acquired immune deficiency syndrome (AIDS) contributes to severe and widespread infections and unrestricted growth by certain tumors. To determine whether monocyte dysfunction contributes to this immunosuppressed condition, we investigated monocyte chemotaxis in patients with AIDS. Using three different chemotactic stimuli, N-formylmethionylleucylphenylalanine, lymphocyte-derived chemotactic factor, and C5a des Arg, we studied the chemotactic responses of monocytes from seven homosexual men with AIDS, three homosexuals with lymphadenopathy and an abnormal immunological profile, seven healthy homosexual men, and 23 heterosexual control individuals. Monocytes from each of the AIDS patients with Kaposi's sarcoma and/or opportunistic infection exhibited a marked reduction in chemotaxis to all stimuli compared with the healthy control subjects. The reduced chemotactic responses were observed over a wide range of concentrations for each stimulus. Monocytes from AIDS patients who had clinically apparent opportunistic infection(s) exhibited a greater reduction in monocyte migration to all three stimuli than monocytes from the AIDS patient with only Kaposi's sarcoma. Monocytes from each of three homosexuals with lymphadenopathy and an abnormal immunological profile exhibited decreased chemotactic responses that were intermediate between those of the AIDS patients and the healthy heterosexual control subjects. In contrast to these findings, monocytes from each of seven healthy homosexuals exhibited normal chemotactic responses to the same stimuli. In addition, monocytes from AIDS patients exhibited reduced chemotaxis to soluble products of Giardia lamblia, one of several protozoan parasites prevalent in AIDS patients. Thus the immune abnormality in AIDS, previously thought to involve only the T-, B-, and natural killer lymphocytes, extends to the monocyte-macrophage. Defective monocyte migratory function may contribute to

    Summary Introduction: This prospective study was planned to investigate the frequency and relationship of acquired von Willebrand syndrome (AVWS) with aortic and pulmonary stenosis in patients. Methods: A total of 84 children, ranging from two to 18 years of age, were enrolled in this study. Of these, 28 had isolated aortic stenosis, 32 had isolated pulmonary stenosis and 24 were healthy. Children with aortic and pulmonary stenosis associated with other congenital heart diseases were excluded. Children with hypothyroidism, renal or liver disease, malignancy or autoimmune disease were also excluded. Wholeblood count, blood group, factor VIII level, prothrombin time (PT), activated partial thromboplastin time (aPTT), von Willebrand factor antigen (VWF:Ag), ristocetin co-factor (VWF:RCo), and bleeding time using a platelet-function analyser (PFA-100) were performed in all patients. All of the children in the study underwent a detailed physical examination and echocardiographic evaluation. Results: A history of bleeding was positive in 18% of the aortic stenosis group, 9% of the pulmonary stenosis group, and 4% of the control group. Seven of 60 (12%) patients had laboratory findings that implied a diagnosis of AVWS, and two of these (28%) had a history of bleeding. The frequency of AVWS was 14% in patients with aortic stenosis and 9% in those with pulmonary stenosis. Conclusion: AVWS is not rare in stenotic obstructive cardiac diseases. A detailed history of bleeding should be taken from patients with valvular disease. Even if the history is negative, whole blood count, PT and aPTT should be performed. If necessary, PFA-100 closure time and further tests should be planned for the diagnosis of AVWS. PMID:27841910

    Lack of recognition of human immunodeficiency virus (HIV) infection especially in children and delayed implementation of effective control programs makes HIV infection as a major cause for concern. Information on HIV epidemiology in Iran as well as other Islamic countries is limited. The aim of our study was to describe the clinical manifestation and laboratory finding of HIV infected children who were admitted to a referral Children Medical Center (CMC) in Tehran, Iran, during 11 years from January 2002 to January 2013. This was a retrospective study carried out over a period of 11 years. The records of all patients attending to the CMC with confirmed acquired immunodeficiency syndrome (AIDS) were screened. The patients were evaluated for social circumstance, family history, age, gender, clinical, and laboratory features. Clinical data including fever, respiratory distress, diarrhea, rash, etc. as well as laboratory tests including complete blood count, serum glucose level, electrolytes, liver function test, cultures, CD4 lymphocyte count were evaluated. During the study period, 32 HIV positive children were enrolled. The majority of patients were presented with weight loss, prolonged fever, respiratory infection and chronic diarrhea. In this study, salmonella infections as well as streptococcal pneumonia and candida infections followed by, tuberculosis and Pseudomonas aeruginosa infections were the predominant opportunistic infections. Since the number of HIV-positive children has been alarmingly increasing in recent years and perinatal transmission is the most common route of HIV infection in children, essential recommendations for prenatal HIV testing as well as appropriate antiretroviral therapy by HIV infected mothers are needed.

    The purpose was to determine the prevalence and related factors of vitamin D (VitD) insufficiency in adolescents and young adults with perinatally acquired human immunodeficiency virus. A cohort of 65 patients (17.6 ± 2 years) at the Federal University of Rio de Janeiro, Brazil, were examined for pubertal development, nutrition, serum parathormone and serum 25-hydroxyvitamin D [s25(OH)D]. s25(OH)D levels < 30 ng/mL (< 75 nmol/L) were defined as VitD insufficiency. CD4+ T-cell counts and viral load, history of worst clinical status, immunologic status as nadir, current immunologic status, and antiretroviral (ART) regimen were also evaluated as risk factors for VitD insufficiency. Mean s25(OH)D was 37.7 ± 13.9 ng/mL and 29.2% had VitD insufficiency. There was no difference between VitD status and gender, age, nutritional status, clinical and immunological classification, and type of ART. Only VitD consumption showed tendency of association with s25(OH)D (p = 0.064). Individuals analysed in summer/autumn season had a higher s25(OH)D compared to the ones analysed in winter/spring (42.6 ± 14.9 vs. 34.0 ± 11.9, p = 0.011). Although, the frequency of VitD insufficiency did not differ statistically between the groups (summer/autumn 17.9% vs. winter/spring 37.8%, p = 0.102), we suggest to monitor s25(OH)D in seropositive adolescents and young adults, especially during winter/spring months, even in sunny regions.

    To our knowledge, an association between human immunodeficiency virus infection and pseudo-Cushing's syndrome has not previously been described. We describe four HIV-infected patients with pseudo-Cushing's syndrome, characterized by striking dorsocervical and submandibular fat accumulation and central obesity. In each case, cortisol levels were either normal or suppressed adequately with administration of dexamethasone, excluding the diagnosis of true Cushing's syndrome. Immune function and weight improved significantly preceding the development of pseudo-Cushing's syndrome. Three of the four patients were taking a common protease inhibitor at the onset of symptoms, and the fourth reported the exacerbation of his symptoms with the addition of a protease inhibitor. The observed characteristic pattern of fat deposition may be attributable to a specific effect of new antiretroviral therapies or may relate to recovery independent of medication usage. Distinguishing between pseudo-Cushing's syndrome and true Cushing's syndrome is critical for preventing the unnecessary and potentially harmful treatment of such patients. Further research into the mechanisms of this novel phenomenon is needed.

    Hepatic morphology and immunocytology were evaluated in 4 children with clinical and immunologic characteristics of the acquired immune deficiency syndrome or acquired immune deficiency syndrome related complex. All 4 children had hepatomegaly and increased serum alanine and aspartate aminotransferase activity. Both lobular and portal changes were noted. Lymphocytic infiltration, piecemeal necrosis, hepatocellular and bile duct damage, sinusoidal cell hyperplasia, and endothelialitis were prominent. Vesicular rosettes in sinusoidal lymphocytes and tubuloreticular structures in sinusoidal endothelial cells were demonstrated by electron microscopy. The lymphocytic infiltrate in both the lobular and portal spaces was characterized by a relative increase of cytotoxic/suppressor (T8) cells. Hepatitis may be a common feature of pediatric acquired immune deficiency syndrome and acquired immune deficiency syndrome-related complex. Although the histopathologic changes are consistent with chronic active hepatitis, the specific pathogenesis remains to be determined.

    We report the case of a boy whose development was normal until the age of three when regression with loss of speech occurred. Other anomalies included eating and sleep disorders, sterotyped behavior disorders, suggesting infantile psychosis. The electroencephalogram evidenced paroxysmal anomalies, particularly during sleep, with no clinical seizures. The diagnosis of epilepsia-acquired aphasia syndrome (Landau-Kleffner syndrome) was made. The psychotic disorders were not considered as a differential diagnosis but rather as intertwined with the elements of the syndrome. The relationship between acquired aphasia and psychosis are discussed.

    Hemophagocytic lymphohistiocytosis (HLH) is a syndrome characterized by severe hyperinflammation due to an overwhelming ineffective immune response to different triggers. Most important symptoms are fever, hepatosplenomegaly and cytopenias. Biochemical signs include elevated ferritin, hypertriglyceridemia and low fibrinogen. Hemophagocytosis in the bone marrow is a hallmark of this syndrome. Based on the pathogenetic mechanism, it can be classified into primary (inherited) or secondary (acquired) HLH. We report, to our knowledge, the first case of acquired hemophagocytic syndrome that arose in a 20-year-old man affected by synovial sarcoma as a complication during chemotherapy. PMID:28031902

    Parametric and semiparametric competing risks methods were used to estimate proportions, timing, and predictors of acquired immune deficiency syndrome (AIDS)-related and non-AIDS-related mortality among individuals both positive and negative for the human immunodeficiency syndrome (HIV) in the Multicenter AIDS Cohort Study (MACS) and Women's Interagency HIV Study (WIHS) from 1984 to 2008 and 1996 to 2008, respectively. Among HIV-positive MACS participants, the proportion of deaths unrelated to AIDS increased from 6% before the introduction of highly active antiretroviral therapy (HAART) (before 1996) to 53% in the HAART era (P < 0.01); the median age of persons who died from non-AIDS-related causes after age 35 years increased from 49.0 to 66.0 years (P < 0.01). In both cohorts during the HAART era, median ages at time of non-AIDS-related death were younger for HIV-positive individuals than for comparable HIV-negative individuals (8.7 years younger in MACS (P < 0.01) and 7.6 years younger in WIHS (P < 0.01)). In a multivariate proportional cause-specific hazards model, unemployment (for non-AIDS death, hazard ratio (HR) = 1.8; for AIDS death, HR = 2.3), depression (for non-AIDS death, HR = 1.4; for AIDS death, HR = 1.4), and hepatitis B or C infection (for non-AIDS death, HR = 1.8, for AIDS death; HR = 1.4) were significantly (P < 0.05) associated with higher hazards of both non-AIDS and AIDS mortality among HIV-positive individuals in the HAART era, independent of study cohort. The results illuminate the changing face of mortality among the growing population infected with HIV.

    Serum IgG subclass levels were measured by an indirect competitive immunoenzymatic assay with monoclonal antibodies in 61 adult patients of different geographic origins affected either with the lymphoadenopathy syndrome (LAS, 46 cases) or with the acquired immune deficiency syndrome (AIDS, 15 cases). In spite of considerable variations from patient to patient, IgG-1 and IgG-3 levels were higher than in normal Caucasians, with IgG-1 levels much more elevated in LAS than in AIDS patients. In Caucasians with AIDS or LAS, IgG-4 levels were low. IgG-2 levels tended to be low and correlated negatively with IgG-1 levels. IgG subclass imbalances were especially striking in patients with lymphoid interstitial pneumonitis. The results suggest that the IgG increase predominantly affects the less T-dependent subclasses. The low levels of the more T-dependent isotypes do not appear to play a clear role in the occurrence of pyogenic infections in certain patients. PMID:3955884

    The AIDS epidemic has, to date, had only a minimal impact in India; however, given the low health status of the population and the lack of adequate health care facilities, the emergence of AIDS on a wider scale would be devastating. India's human immunodeficiency virus (HIV) seropositivity rate now stands at about 2-3/1000 people tested. In what is suspected to be a racially motivated move, the Government of India has embarked on testing all foreign students (most of whom are from Africa) for HIV and is returning all those who test seropositive to their countries of origin. Of concern is the steady increase in HIV infection in professional blood donors (1.5/1000 in late 1988). Mandatory screening of donated blood is prohibitively expensive in India, and none of the 9 companies that manufacture blood products in India test their donors for HIV infection. Another concern is the finding that 1 of every 6 prostitutes in Bombay is infected with HIV. The response of the Indian Government to the AIDS threat has tended to be punitive toward AIDS victims rather than based on a sound preventive strategy. For example, the 1989 AIDS Prevention Bill forces individuals who are infected with HIV to reveal their past sexual partners, empowers authorities to hospitalize AIDS victims and drug addicts, and contains no provisions to protect the human and civil rights of AIDS victims. The mass media have treated AIDS in a sensationalized manner rather than presenting scientific information about the prevention and transmission of the disease. It is essential that the Government of India--and all world governments--realize that punitive measures will do little to reduce the spread of AIDS. Needed, instead, is a global prevention and control effort based on generosity and compassion.

    Autoimmune cytopenia is a frequent manifestation of primary immunodeficiencies. Two siblings presented with Evans syndrome, viral infections, and progressive leukopenia. DNA available from one patient showed a homozygous frameshift mutation in tripeptidyl peptidase II (TPP2) abolishing protein expression. TPP2 is a serine exopeptidase involved in extralysosomal peptide degradation. Its deficiency in mice activates cell death programs and premature senescence. Similar to cells from naïve, uninfected TPP2-deficient mice, patient cells showed increased major histocompatibility complex I expression and most CD8+ T-cells had a senescent CCR7-CD127−CD28−CD57+ phenotype with poor proliferative responses and enhanced staurosporine-induced apoptosis. T-cells showed increased expression of the effector molecules perforin and interferon-γ with high expression of the transcription factor T-bet. Age-associated B-cells with a CD21− CD11c+ phenotype expressing T-bet were increased in humans and mice, combined with antinuclear antibodies. Moreover, markers of senescence were also present in human and murine TPP2-deficient fibroblasts. Telomere lengths were normal in patient fibroblasts and granulocytes, and low normal in lymphocytes, which were compatible with activation of stress-induced rather than replicative senescence programs. TPP2 deficiency is the first primary immunodeficiency linking premature immunosenescence to severe autoimmunity. Determination of senescent lymphocytes should be part of the diagnostic evaluation of children with refractory multilineage cytopenias. PMID:25414442

    Autoimmune lymphoproliferative syndrome (ALPS) is mainly caused by defects in the CD95 pathway. Raised CD3+TCRαβ+CD4-CD8- double negative T cells and impaired T cell apoptosis are hallmarks of the disease. In contrast, the B cell compartment has been less well studied. We found an altered distribution of B cell subsets with raised transitional B cells and reduced marginal zone B cells, switched memory B cells and plasma blasts in most of 22 analyzed ALPS patients. Moreover, 5 out of 66 ALPS patients presented with low IgG and susceptibility to infection revealing a significant overlap between ALPS and common variable immunodeficiency (CVID). In patients presenting with lymphoproliferation, cytopenia, hypogammaglobulinemia and impaired B cell differentiation, serum biomarkers were helpful in addition to apoptosis tests for the identification of ALPS patients. Our observations may indicate a role for apoptosis defects in some diseases currently classified as CVID.

    Analysis of tests of coagulation and fibrinolysis from 20 adult nephrotics prior to the onset of therapy disclosed that 40 percent had low factor XII levels. The mean factor XI was normal. The platelet count and fibrinogen concentration were elevated. The findings of this study on adults are similar to those of Honig and Lindley21 in the nephrotic syndrome of childhood. Subjects with minimal change disease constituted a small (15 percent) but readily segregated subpopulation without evidence of fibrinolysis in association with low factor XII activity. Prolongation of the activated partial thromboplastin time corresponded in every instance with factor XII activities of ≤30 percent. Lengthening of the one stage prothrombin time was not directly attributable to factor deficiencies. PMID:7120469

    Immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome is a rare monogenic primary immunodeficiency (PID) due to mutations of FOXP3, a key transcription factor for naturally occurring (n) regulatory T (Treg) cells. The dysfunction of Treg cells is the main pathogenic event leading to the multi-organ autoimmunity that characterizes IPEX syndrome, a paradigm of genetically determined PID with autoimmunity. IPEX has a severe early onset and can become rapidly fatal within the first year of life regardless of the type and site of the mutation. The initial presenting symptoms are severe enteritis and/or type-1 diabetes mellitus, alone or in combination with eczema and elevated serum IgE. Other autoimmune symptoms, such as hypothyroidism, cytopenia, hepatitis, nephropathy, arthritis, and alopecia can develop in patients who survive the initial acute phase. The current therapeutic options for IPEX patients are limited. Supportive and replacement therapies combined with pharmacological immunosuppression are required to control symptoms at onset. However, these procedures can allow only a reduction of the clinical manifestations without a permanent control of the disease. The only known effective cure for IPEX syndrome is hematopoietic stem cell transplantation, but it is always limited by the availability of a suitable donor and the lack of specific guidelines for bone marrow transplant in the context of this disease. This review aims to summarize the clinical histories and genomic mutations of the IPEX patients described in the literature to date. We will focus on the clinical and immunological features that allow differential diagnosis of IPEX syndrome and distinguish it from other PID with autoimmunity. The efficacy of the current therapies will be reviewed, and possible innovative approaches, based on the latest highlights of the pathogenesis to treat this severe primary autoimmune disease of childhood, will be discussed.

    Although various coagulation abnormalities occur in patients with Gaucher disease (GD), von Willebrand factor (vWF) deficiency has rarely been reported. A retrospective review of six treatment naïve cases with GD and concomitant vWF deficiency over a 12-year-period in a single center is presented. All patients had a personal history of prior hemorrhages. Based on both reduced level of vWF antigen (vWF:Ag, range 14-56%) and ristocetin cofactor activity (vWF:RCo, range 12-53%), with a vWF:RCo/Ag ratio >0.7, the diagnosis of type 1 von Willebrand disease was made in all six cases. During enzyme replacement therapy (ERT) of a 2-year duration all patients normalized their vWF:Ag levels. Based on the positive ERT effect on vWF:Ag levels, vWF deficiency was assumed to be acquired. It should be noted that beside vWF deficiency four patients with GD exhibited mild thrombocytopenia (range 81-131×10(9)/L) and three had additional hemostatic defects (reduced collagen platelet aggregation, FV, FXI and FXII deficiencies).

    Rubber band syndrome is a rare entity seen in younger children mainly in communities where rubber bands are worn around the wrist for decorative purposes. When the band is worn for a long duration, it burrows through the skin and soft tissues resulting in distal edema, loss of function, and even damage to the neurovascular structures. These symptoms are difficult to relate to this rare but typical condition. We report a case of a 2¾-year-old girl with the history of a linear circumferential scar at the right wrist combined with the limited use of a swollen hand for several weeks. The child was taken to surgery with the purpose to release the red, indurated scar and eliminate the lymphatic congestion. A rubber band was found lying in a plane superficial to the flexor tendons but had cut through the superficial branch of the radial nerve and partially through the abductor pollicis longus tendon. The band was removed and the lacerated structures were repaired. The child had excellent recovery postoperatively. The cardinal features of a linear constricting scar around the wrist in the presence of a swollen hand should always alert the clinician to the possibility of a forgotten band around the wrist, which might have burrowed into the soft tissues for a period. Early recognition may be important to prevent further damage of essential structures.

    Microglial nodules associated with opportunistic and HIV-related lesions are frequently found in the brains of AIDS patients. However, in many cases, the causative agent is only presumptively suspected. We reviewed 199 brains of AIDS patients with micronodular lesions to clarify their etiology by immunohistochemistry (to Toxoplasma gondii, cytomegalovirus, herpes simplex virus I/II, varicella zoster virus and HIV-p24 core protein), PCR (for herpetic viruses and Mycobacterium tuberculosis) and electron microscopy. Productive HIV infection was observed in 110 cases (55.1%): 30 cases with Toxoplasma gondii encephalitis, 30 with cytomegalovirus encephalitis, eight with multiple cerebral diseases, while in the remaining 42 cases HIV was the only pathogenetic agent. Multinucleated giant cells (hallmark of HIV infection) were found in the MGNs of 85/110 cases with HIV-related lesions; the remaining 25 cases had only p24 positive cells but no multinucleated giant cells. In these latter cases the micronodular lesions had been initially attributed to the main opportunistic agent found in the brain, or defined as subacute encephalitis. Individual microglial nodules positive for an opportunistic pathogen were generally negative for HIV antigens. In 13 cases no opportunistic agent or HIV productive infection was found. In these cases, PCR and electron microscopy examination for HIV and other viral infections were negative. Our data suggest that HIV-immunohistochemistry should be used for the etiological diagnosis of micronodular lesions in AIDS brains, even in the presence of other pathogens. After extensive search, the etiology of the microglial nodules remains unknown in only a small percentage of cases.

    Introducción: el carcinoma escamoso de la conjuntiva (CEC) es un tumor maligno epitelial de la mucosa conjuntival, de etiología multifactorial. Existen varias alternativas de tratamiento para el control de esta enfermedad con diferentes resultados terapéuticos. El objetivo del trabajo fue evaluar la respuesta antitumoral de la preparación de una formulación de cisplatino en 3 pacientes con HIV y CEC recidivante, candidatos a tratamiento de enucleación y exenteración orbitaria, y evaluar los efectos adversos que se presentaron con la administración de la formulación aplicada. Métodos: fueron tratados 3 pacientes masculinos, caucásicos, con media de edad 37 años, a los que se les realizó cirugía exerética y se les administraron 3 ciclos de quimioterapia subconjuntival, con duración de 3 meses. Resultados: todos los pacientes conservaron sus ojos y la visión. No hubo persistencia ni aparecieron recidivas tumorales durante el periodo evaluado. Un paciente falleció por progresión del HIV 2 años después de finalizado el tratamiento, mantuvo visión conservada y sin actividad tumoral. Conclusión: el tratamiento con quimioterapia subconjuntival adyuvante a la cirugía resulta eficaz y es tolerable en la población de pacientes tratados.

    1999-01-01

    This article reports on the prevalence of AIDS and sexually transmitted diseases (STDs) in Southeast Asia. The spread of HIV infection in this region has been predicted to be worse than that of Africa. The high-prevalence countries are Thailand, Cambodia, and Myanmar, where prevalence rates in the population at risk (15-49 year olds) are up to 2%; while low prevalence countries with rates of 0.1% include the Philippines, Indonesia, Laos, Brunei, and Singapore. Heterosexual transmission in Southeast Asia is the main mode of spread of HIV. Another route is through migration, rural-to-urban or international migration of people seeking jobs; with concurrent loneliness and anonymity, they become vulnerable to STDs and HIV infection. Intravenous drug use poses an increasing risk of transmission. The unavailability of data in some countries makes it difficult to evaluate the extent of the epidemic or if there's an impending epidemic. There are a number of caveats to the data compilation from various countries. These include the following: under-reporting of cases; underdiagnosis; missed diagnosis; and differences in the time of data collection. It is clear that poverty, illiteracy, and poor access to educational information in most countries in this region facilitate the rapid spread of HIV. These coupled with lack of primary health care services, and in most instances, enormously high cost of drugs make the pain and suffering due to the HIV/AIDS epidemic a human disaster far worse than the ravages of war.

    Cystoisospora belli is a coccidian protozoan that can cause chronic diarrhoea, acalculous cholecystitis and cholangiopathy in AIDS patients. We applied molecular methods to identify Cystoisospora at species level in AIDS patients presenting with and without the presence of unizoites in lamina propria. Coprological and histological analyses were performed in stool and/or biopsy samples from 8 Cystoisospora-infected patients. DNA from the same samples was used to amplify 2 fragments of the SSU-rRNA gene and the ITS-1 region. Sequencing of the resulting amplicons identified C. belli infections in all cases, independent of the presence or absence of unizoite tissue cysts. Further work should be considered in order to find molecular targets related to strain variations in C. belli.

    The authors retrospectively reviewed the medical records of HIV/AIDS patients who were admitted to the medical service, Siriraj Hospital from January 1, 2002 through December 31, 2002. Demographics, CD4 lymphocyte counts, discharge diagnoses, the incidence of Pneumocystis carinii pneumonia (PCP), cerebral toxoplasmosis and cryptococcosis in patients who received and did not receive appropriate chemoprophylaxis against those opportunistic infections when indicated, and outcome of the patients were collected. Three hundred medical records of 286 HIV/AIDS patients were available for review. One hundred and seventy two patients (60.1%) were male. Mean age of the patients was 36.8 +/- 9.91 years (range 14-74). The mean CD4 lymphocyte count that was determined in 165 patients was 74.7 +/- 134.21 cells/mm3 (range 0-894). Of the 300 admissions, 36 per cent were newly diagnosed HIV infection. Only 23 (7.7%) patients had received antiretroviral drugs at the time of hospitalization. The leading HIV-related diseases were tuberculosis (29.3%), Pneumocystis carinii pneumonia (18.7%), and cryptococcosis (15.7%). The rest of them included cytomegalovirus diseases (6.3%), lymphoma (6.3%), Salmonella bacteremia (6%), cerebral toxoplasmosis (5.7%), cryptosporidiosis (5.3%), disseminated Mycobacterium avium complex infection (1.0%), extrapulmonary histoplasmosis (1.0%), Candida esophagitis (1.0%), progressive multifocal leukoencephalopathy (1.0%), and rhodococcosis (0.7%). Among those for whom HIV infection was established and chemoprophylaxis for PCP, cerebral toxoplasmosis and cryptococcosis were indicated, 9.8 per cent vs 28.2 per cent, 3.6 per cent vs 5.1 per cent, and 10 per cent vs 15.2 per cent of whom received and did not receive the appropriate chemoprophylaxis developed PCP, cerebral toxoplasmosis and cryptococcosis respectively. One hundred and ninety (63.3%) patients were alive at discharge, 84 (28.0%) had died, 21 (7%) were referred to other hospitals, and 5 (1.7%) left hospital against medical advice. The mortality rate in newly diagnosed HIV and in known HIV without antiretroviral treatment were comparable but much lower in known HIV-infected patients who received antiretroviral therapy. Secondary prevention by detection of HIV-infected patients while they are asymptomatic and providing them with appropriate chemoprophylaxis against specific opportunistic infections as well as appropriate antiretroviral treatment would decrease morbidity, mortality, and improve the quality of life of HIV-infected patients in Thailand.

    Since 1985, OCEAC, the organization for control of widespread endemic disease in Central Africa, has managed an epidemiological surveillance programme concerning HIV infection and AIDS in six countries of the Sub-Region: Cameroon, Tchad, Central African Republic, Congo, Equatorial Guinea and Gabon. This programme consists in evaluating longitudinally incidence rates of infection and clinical cases, and mortality rates. It is based on a selective strategy using a network of sentinels (hospitals and maternity care consultation centers), completed by cross sectional epidemiological studies. Thanks to this programme high risk groups of population, high risk places and high risk activities have been identified. These observations will be used to plan national prevention programmes on AIDS.

    There is dearth of information on the haematologic complications of HIV/AIDS in this country. The aim of this work was to evaluate the importance of peripheral blood and bone marrow changes in a population of adult Nigerians managed for symptomatic HIV infection at the OAUTHC, Ile-Ife, between 1995 and 2001. The study was prospective. Peripheral blood cells counts (haemetocrit value, total and differential leucocyte counts, and platelet counts) and bone marrow cytology of serologically confirmed HIV/AIDS patients seen within the study period were studied. The associated opportunistic disorder (s) was noted for each patient. Individuals with conditions that are ordinarily associated with haematologic disorders (e.g. cancer and inherited haemoglobinopathies) and patients diagnosed in pregnancy were not included. Significant levels of differences in mean values of blood cells within groups were determined by student's t-test. Seventy-two patients were recorded, out of which 49 (68%) were evaluable. There were 32 (65%) males and 17 (35%) females, all aged between 21 and 51 (median = 36) years. None of the patients had conventional antiretroviral therapy. Lymphopenia (lymphocytes < 2 x 10(9)/l) was seen in 64.4% of the patients, 50% and over 40% of the patients had moderate-severe anaemia and neutropenia, respectively. Blood cells values were not significantly different between patients with mild disease and those with moderate-severe diseases. The most characteristic marrow abnormality was the abundance of naked nuclei of megakarycytes in 20 (60.1%) of the patients. Dysplatic changes were evident in 15 (45.5%) of the bone marrow specimens studied. Such changes are characterised by dysgranulopoiesis, Pelger-Huet anomaly in some of the mature granulocytes, vacuolation of some erythroid and myeloid cells, unilobular micromegakaryocytes and megaloblastic erythroid precursors (15.1% of the marrow).

    In Mexico cryptococosis ranks third in frequency among the mycoses ocurring as complications in AIDS patients. Neither the prevalence of the two varieties of C. neoformans in these patients nor the morphological and physiological changes suffered by these strains in AIDS patients are known. A total of 60 isolates were obtained from patients with AIDS from the Hospital de Infectología, Centro Médico "La Raza" IMSS. The identity of each isolate was established by: growth at 37 degrees C, colony and microscopic characteristics, urease and phenoloxidase activity, carbon sources assimilation. The canavanine glycine-bromothymol blue agar was used to distinguish C. neoformans var. neoformans and C. neoformans var. gattii. Pathogenicity in mice was also tested. Fifty one isolates of C. neoformans var. neoformans and nine of C. neoformans var. gattii were identified. All strains grew well at 37 degrees C, urease and phenoloxidase were positive, the morphology and the auxanographic profile were variable. C. neoformans var. neoformans was more virulent in mouse than C. neoformans var. gattii. This study has confirmed the presence of the two varieties of C. neoformans in Mexico with 85% prevalence of var. neoformans and 15% of var. gattii in AIDS patients. This frequency was higher than in reports from other countries.

    A 45-year-old man with AIDS presented with extensive erythema and scaling involving the face, trunk, and upper and lower extremities, and mild nail dystrophy. The patient had been diagnosed with psoriasis 2 years previously, and at the time of presentation was using emollients and topical corticosteroid creams with little improvement. He was receiving zidovudine, lamivudine, trimethoprim/sulfamethoxazole, acyclovir, rifabutin, and hydroxyzine. Pertinent laboratory data included CD4 lymphocytes (10 cells/mm(3)), viral load (32,000 copies per mL) white blood cell count (3.4 x 10(3)/microL), hemoglobin (13.5 g/dL), and platelets (204 x 10(3)/microL). Because of the extensive eruption and lack of response to topical agents, the patient was started on acitretin 25 mg daily. The patient had shown no signs of improvement 4 weeks later and was noted to have brownish gray crusted plaques involving the beard area, neck, upper part of the back, arms, trunk, genitals, and thighs in addition to his erythroderma (Figure 1 and Figure 2). Microscopic examination of scales from the upper part of the back revealed numerous scabies mites and eggs. He was then treated with lindane shampoo on the scalp and beard area and permethrin 5% cream to the body. The patient returned 2 weeks later with some improvement after thrice-weekly applications of this regimen; however, scrapings from the trunk once again revealed live scabies mites. Microscopic examination of scales that had fallen on the examination table revealed multiple mites and eggs. The patient was then given permethrin 5% cream, which he applied 3 times a week for 2 weeks, and 1 dose of oral ivermectin, 200 micro/kg. This resulted in a marked decrease in crusting and scaling. With resolution of the scabies lesions, the patient displayed marked erythema and scaling of the trunk and extremities consistent with generalized psoriasis (Figure 3). Treatment with acitretin resulted in gradual resolution of the erythroderma. A few months later, the patient presented with nodules on the upper part of the back, which on biopsy revealed a scabies mite (Figure 4).

The patients belonged to two different epidemiological groups: the first group included thirteen french homosexual men, the second group included 6 Haitians, 6 Africans and a Pakistanian, none of them admit homosexual activity. The clinical manifestations were: chronic watery diarrhea in 17 cases, bloody diarrhea in 2 cases; loss of weight in the 26 cases; dysphagia in five cases; jaundice in one patient (due to Kaposi sarcoma of the ampulla of Vater). The digestive lesions found, alone or associated, were necrotizing enteritis (2), ulcerative colitis (1), pseudomembranous colitis (1), Candida esophagitis (10), erythematous duodenitis (6), proctitis (4), Kaposi sarcoma (3), diffuse (2) or localized (1). Thirteen patients out of the 26 presented opportunistic digestive infections due to one or several germs. These were 10 cases of esophageal infection (due to Candida albicans) and 8 cases of enterocolonic infection due to Cytomegalovirus (3 cases), Cryptosporidium (3 cases), Mycobacterium avium intracellulare (1 case), Cryptococcus neoformans (1 case). The other digestive infections cases were due to non-opportunistic pathogens: Entamoeba histolytica (3 cases); Giardia lamblia (3 cases); Strongyloides stercoralis (2 cases); Salmonella typhi (2 cases); Shigella (1 case); Herpes simplex virus (1 case). No difference was noticed between the homosexual and the heterosexual groups with respect to the nature and the frequency of the digestive infections.

    Ménétrier disease is a rare disorder of unknown etiology. An overexpression of TGF-alpha has been proposed to play a role in the pathophysiology. HIV-1 tat gene product has been shown to stimulate TGF-alpha production leading to a positive feedback autocrine loop. The case of a 41-year-old male with AIDS who presented with weight loss, abdominal pain, ascites, edema, nausea, vomiting, and diarrhea is discussed. A computed tomography (CT) scan of the abdomen showed avid enhancement of the stomach mucosa. Magnetic resonance angiography revealed gastric and small bowel distention with diffuse wall thickening. Biopsies of the stomach showed marked foveolar hyperplasia with active inflammation and gland changes consistent with Ménétrier disease.

    Immunodeficiencies are characterized as primary (genetic) or secondary (acquired). Primary immunodeficiencies are relatively uncommon; however, clinically, they present a significant challenge to the practitioner, especially if the underlying disorder goes unrecognized. Secondary immunodeficiencies may present at any age, but failure of passive transfer in neonatal foals is most commonly encountered. This article provides a general overview of clinical signs and diagnosis of primary and secondary immunodeficiencies currently recognized in horses.

    Three cases of small bowel lymphoma in young homosexual men are presented. All three had acquired immune deficiency syndrome as demonstrated by demography, sexual history, cachexia, opportunistic infections by Cytomegalovirus, Pneumocystis carinii, atypical Mycobacterium, Candida, and/or evidence of immune deficiency, such as skin test anergy, lymphopenia, inversion of T-helper/T-suppressor ratio, and diminished lymphocyte response to either phytohemmaglutinin or pokeweed mitogen. All had peripheral and/or abdominal lymphadenopathy, and gastrointestinal symptoms, e.g., diarrhea, spasms, constipation, and oral candidiasis. The diagnosis of lymphoma was made at laparotomy in all cases. All three had complete removal of localized tumor (stage Ie or IIe), yet died within 6 months of surgery and/or chemotherapy. Thus gastrointestinal complaints may not always be related to "gay bowel" syndrome, or other infectious diseases in patients with acquired immune deficiency syndrome. Small intestinal lymphoma should be added to the list of neoplasms to which this group is susceptible.

    Elimination of a rifamycin from the treatment regimen for tuberculosis negatively impacts outcomes. Cross-reactivity between the rifamycins after drug eruptions is unclear. We report 6 consecutive human immunodeficiency virus-infected patients with rifampicin-associated drug rash with eosinophilia and systemic symptoms (DRESS) syndrome confirmed on diagnostic rechallenge. The patients subsequently tolerated rifabutin. These data inform clinical management of tuberculosis-associated drug reactions. PMID:27419190

    Acquired von Willebrand (vW) syndrome is a rare bleeding disorder which is frequently associated with immunological, malignant or cardiovascular disorders. The underlying pathomechanisms, particularly in patients with IgM monoclonal gammopathies, often remain unknown. We report a patient with indolent small B-cell lymphoma (immunocytoma) and plasmacytic differentiation with an IgM kappa paraprotein who was admitted with retroperitoneal haematoma. Medical history and coagulation testing were consistent with acquired vW syndrome. vW immunohistochemistry showed normal cytoplasmic labelling of endothelial cells and megakaryocytes, whereas the lymphomatous infiltrate was negative. Acquired vW syndrome due to adsorption of vW factor on malignant cells was thus excluded. In the multimeric analysis, all multimers were present similar to that in type 1 vW syndrome, but the triplet structures were blurred. The bands on serum immunofixation electrophoresis were also atypically broadened, which suggested complex formation between the IgM and vW factor. Immunoprecipitation studies showed that the 176-kDa proteolytic fragment of vW factor co-precipitated with the IgM paraprotein in the patient but not in the controls, suggesting a specific interaction between vW factor and the paraprotein in the patient. The patient required surgery and was successfully managed by chemotherapy consisting of rituximab and fludarabin as well as plasma exchange.

    Henan Province in China has a major epidemic of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS). Chinese medicine (CM) has been used throughout the last decade, and a management modality was developed, which can be described by unified-planning, graded-administration, and centralized-controlling (UGC). The UGC modality has one primary concept (patient-centered medicine from CM theory), four basic foundations (classifying administrative region, characteristics of CM on disease treatment, health resource conditions, and distribution of patients living with HIV), six important relationships (the "three uniformities and three combinations," and the six relationships therein guide the treatment of AIDS with CM), and four key sections (management, operation, records, and evaluation). In this article, the authors introduce the UGC modality, which could be beneficial to developing countries or resource-limited areas for the management of chronic infectious disease.

    One hundred hemophiliacs were studied for serological evidence of infection with cytomegalovirus (CMV), Epstein-Barr virus (EBV), and hepatitis B virus. Ninety-eight percent had markers of hepatitis B infection, while 69% had antibody to EBV and only 42% had antibody to CMV, suggesting that factor VIII preparations do not transmit EBV and CMV efficiently. Seventy-one percent of those seropositive to EBV had an antibody pattern suggestive of active infection, as compared with 23% of healthy young adult blood donors. These findings make the patients with hemophilia an unusually favorable population for the study of the role of persistent viral infection in the immunodeficiency now found to be widespread in groups at high risk for acquired immune deficiency syndrome (AIDS) and for the contribution of CMV and EBV to AIDS itself.

    Autoimmune lymphoproliferative syndrome (ALPS) is a disorder of dysregulated lymphocyte homeostasis. Biomarkers including elevated CD3+TCRαβ+CD4-CD8- double negative T cells (TCRαβ+ DNT), IL-10, sCD95L and vitamin B12 can be used to differentiate between ALPS and common variable immunodeficiency (CVID) patients with an overlapping clinical phenotype. We investigated the utility of ALPS biomarkers in 13 CVID patients with lymphoproliferation and/or autoimmune cytopaenia with comparison to 33 healthy controls. Vitamin B12 (P < 0.01) and IL-10 (P < 0.0001), but not sCD95L or TCRαβ+ DNT, were increased in CVID compared to controls. The 95th percentile for TCRαβ+ DNT in healthy controls was used to define a normal range up to 2.3% of total lymphocytes or 3.4% of T cells. These frequencies lie markedly beyond the cut offs used in current ALPS diagnostic criteria (≥ 1.5% of total lymphocytes or 2.5% of CD3+ lymphocytes), suggesting these limits may have poor specificity for ALPS.

    Compartment Syndrome (CS) is a disease that has 2 etiologies, that of acute events and that of chronic. It occurs when the pressure in a fascia-encased compartment exceeds the profusion pressure in tissue. The end result, when left untreated, is muscle and nerve ischemia that can cause significant morbidity. Nerve paralysis, muscle necrosis and fibrosis and, when occurring in an extremity, loss of the limb are some of the potential outcomes of missed diagnosis. This case series involves 2 cases of CS that where caused by vasculitis with etiologies of human immunodeficiency virus and systemic lupus erythematosis. Autoimmune vasculitis has many systemic and local manifestations, but to our knowledge CS has not been described as one of its sequelae. The following is literature review and presentation of these 2 cases.

    Acquired bone marrow failure syndromes encompass a unique set of disorders characterized by a reduction in the effective production of mature cells by the bone marrow (BM). In the majority of cases, these syndromes are the result of the immune-mediated destruction of hematopoietic stem cells or their progenitors at various stages of differentiation. Microbial infection has also been associated with hematopoietic stem cell injury and may lead to associated transient or persistent BM failure, and recent evidence has highlighted the potential impact of commensal microbes and their metabolites on hematopoiesis. We summarize the interactions between microorganisms and the host immune system and emphasize how they may impact the development of acquired BM failure. PMID:28286502

    Since 1981 a new syndrome of acquired immune deficiency (AIDS) has been recognized. Male homosexuals, male and female intravenous drug abusers, and recipients of blood products (i.e., hemophiliacs) appear to be the populations at risk. The syndrome has been manifested by community-acquired opportunistic infections and/or Kaposi's sarcoma (KS). Otolaryngologic manifestations of AIDS are not infrequent. Thirteen AIDS patients at the National Institutes of Health with KS of the head and neck region are presented. All 13 patients were homosexual or bisexual males. Nine initially presented with KS, five with KS of the head or neck. As a group the patients demonstrated lesions involving the oropharyngeal, tracheobronchial, and gastrointestinal regions. Their clinical course and complications are presented in detail. The mortality rate in this subgroup of AIDS patients is extraordinarily high (62%), with an average longevity of 11 months following initial diagnosis.

    Fifteen patients who had Kaposi's sarcoma in conjunction with the acquired immune deficiency syndrome (AIDS) received radiotherapy to a total of 17 selected lesions. All tumors exhibited at least partial regression, and the majority responded completely. The radiosensitivity of these lesions is similar to that observed in the classic form of the disease. The authors conclude that in appropriately selected cases radiotherapy should be considered the treatment of choice.

Because of the overwhelming suspicion of infection in this patient, this diagnosis was not considered until a gallium scan revealed the typical findings of heterotopic ossification. Because of the increasing utilization of gallium imaging in the AIDS population, every imaging specialist should be aware of this potential disorder.

    Wiedemann-Steiner Syndrome (WSS) is an autosomal dominant disorder characterized by hypertrichosis, short stature, intellectual disability, developmental delay, and facial dysmorphism. Since the original reports by Wiedemann and co-workers, and Steiner and Marques, only a few cases have been described. Recently, the clinical variability of the disorder has more precisely been characterized by Jones and co-workers, who also identified heterozygous KMT2A mutations as the molecular defect underlying this condition. Here, we report on a boy with a complex phenotype overlapping WSS but exhibiting epilepsy, feeding difficulties, microcephaly, and congenital immunodeficiency with low levels of immunoglobulins as additional features. Whole exome sequencing allowed identifying a previously unreported de novo KMT2A missense mutation affecting the DNA binding domain of the methyltransferase. This finding expands the clinical phenotype associated with KMT2A mutations to include immunodeficiency and epilepsy as clinically relevant features for this disorder. © 2016 Wiley Periodicals, Inc.

Herein, we present a rare case of an advanced HIV infection and Rhodoccocus equi (R. equi) pneumonia in a young male who had severe paradoxical immune reconstitution inflammatory syndrome (IRIS). Case Report: A 47-year-old nonsmoking Hispanic man with advanced HIV infection presented with severe acute necrotizing pneumonia secondary to R. equi. Although his initial response to antimicrobial therapy was optimal, he became symptomatic again in spite of continuation of antibiotics as he developed severe paradoxical IRIS 3 weeks after starting a new highly active anti-retroviral therapy (HAART). Conclusions: The diagnosis of IRIS remains challenging because of the wide variations in the clinical presentation and etiologies. In spite of its rarity as an opportunistic pathogen, we recommend that R. equi, an intracellular pathogen, be included in the differential list of pathogens associated with IRIS. PMID:28100903

    Abstract Objectives The purpose of the current study was to develop and evaluate the psychometric properties of a culturally- and stage-of-disease-appropriate measure of complementary and alternative medicine (CAM) use among a population of African-American individuals with acquired immune deficiency syndrome (AIDS) using a mixed-method design. Design Data were collected in two phases. In phase 1, qualitative data were used to refine an existing CAM measure for the specific study population in the present study. In phase 2, this refined instrument was implemented in a larger sample. The resulting numeric data were analyzed to evaluate the psychometric properties of the revised CAM instrument. Setting Data were collected from patients who were receiving care from the infectious disease clinic of a large, public, urban hospital in the Southeastern United States. Subjects Patients were eligible to participate if they (1) were receiving their care from the clinic, (2) had an AIDS diagnosis, (3) were identified as African-American, (4) were ≥21 years of age, (5) spoke English, and (6) were not cognitively impaired. Measures Focus groups in phase 1 were conducted with a semistructured focus group guide. Participants also completed a basic sociodemographic survey. Phase 2 participants used programmed laptops to answer questions about their CAM use and several sociodemographic questions. Results Information from the focus groups prompted some substantive revisions in the already-existing CAM survey. The revised instrument had satisfactory face validity and adequate test–retest reliability (r = 0.79). Furthermore, the instrument factored in a manner that was interpretable and consistent with prior findings. Conclusions In order for human immunodeficiency virus health care providers to provide the best care to their patients, they need to be informed about the types and frequency of CAM use among their patients. This can be accomplished by methodologically developing

    Acquired immune deficiency syndrome (AIDS) is a new disease which has recently alerted the medical world. AIDS may also concern dental practitioners and oral surgeons who may be the first to suspect impairment of immunity in patients presenting opportunistic oral infections. Extraordinary resistance to treatment of dental infections, such as encountered in a 27-year-old man developing AIDS, could also be a sign of immunodepression. Epidemiological features of AIDS indicate transmissibility, and interim recommendations for prevention of spread correspond to the measures appropriate for hepatitis B.

    Unified procedures to control those infections that are transmitted by inoculation of blood are recommended. These should be applied to patients with overt acquired immune deficiency syndrome, persistent generalized lymphadenopathy or hepatitis B, those with serological evidence of infection by HTLV III or hepatitis B virus, and those in medical and social categories with a higher than average prevalence of such infections. Rational infection control measures, based on the known modes of spread, permit efficient management of infected patients, with satisfactory protection of staff and other patients.

    The acquired immune deficiency syndrome (AIDS) appeared in the United States in late 1978 and has spread at an epidemic rate through the four major coastal cities of this country. The disease appears to show the same epidemiologic distribution as hepatitis B virus infection, and for this reason, most investigators feel that this new disease is caused by a blood-borne sexually transmitted virus. A number of viral agents have been suggested as the cause of AIDS, but to date, no virus has been consistently isolated. The most likely candidate is a retrovirus that has recently been introduced into the human population and has found its way into two extremely high-risk groups, namely, promiscuous male homosexuals and intravenous drug abusers. The relationship between Kaposi's sarcoma and cytomegalovirus is still unclear, but evidence is mounting that cytomegalovirus may be the agent that initiates this multifocal malignancy. Multiple factors must be involved in this process. It is known that some immunosuppressed individuals develop Kaposi's sarcoma, which completely resolves when the immunosuppression is reversed; however, in individuals with classical Kaposi's sarcoma, the profound degree of helper T-cell depression that characterizes the acquired immune deficiency syndrome is not seen.

    We studied levels of erythrocyte C3b receptors (E-CR1) and correlated them to the level of circulating immune complexes (CIC) and complement activation in patients with or at risk for acquired immunodeficiency syndrome (AIDS). A significant reduction was found in patients with AIDS (185 +/- 93 CR1/cell), AIDS-related complex, and generalized lymphadenopathy, whereas healthy male homosexuals or normal controls had 434 +/- 193 and 509 +/- 140 CR1/cell, respectively (P less than 0.001). Family studies indicate that this defect is acquired. Reduction in E-CR1 was associated with increased levels of CIC when assayed by binding to Raji cells, but not when tested by C1q binding. Complement activation was assessed by levels of C3bi/C3d-g in plasma, measured with a monoclonal antibody specific for a neoantigen in C3d. AIDS patients had increased C3 activation (2.68 +/- 1.67%) when compared with normal controls (0.9 +/- 0.22%) (P less than 0.01). The decreased E-CR1, the presence of CIC, and C3 activation suggest that complement activation by immune complexes may play a role in the clinical expression of the disease. PMID:2944915

The patient suffered from diffuse large B cell lymphoma (DLBCL), which was successfully treated with R-CHOP chemotherapy, and continued with immunoglobulin supplementation. The patient was free of lymphoma and infectious complications for over 20 months despite her persistent immunodeficiency, but eventually developed colorectal adenocarcinoma. To the best of our knowledge, this is the first reported case of CVID associated with multiple solid tumours and DLBCL.

    Severity criteria for community-acquired pneumonia (CAP) have always excluded patients with human immunodeficiency virus (HIV) infection. A 1-yr, multicenter, prospective observational study of HIV-infected patients with bacterial CAP was done to validate the criteria used in the American Thoracic Society (ATS) guidelines for CAP, and to determine the prognosis-associated factors in the HIV-infected population with bacterial CAP. Overall, 355 cases were included, with an attributable mortality of 9.3%. Patients who met the ATS criteria had a longer hospital stay (p = 0.01), longer duration of fever (p < 0.001), and higher attributable mortality (13.1% versus 3.5%, p = 0.02) than those who did not. Three factors were independently related to mortality: CD4(+) cell count < 100/microl, radiologic progression of disease, and shock. Pleural effusion, cavities, and/or multilobar infiltrates at admission were independently associated with radiologic progression. A prognostic rule based on the five criteria of shock, CD4(+) cell count < 100/microl, pleural effusion, cavities, and multilobar infiltrates had a high negative predictive value for mortality (97.1%). The attributable mortality for severe pneumonia was 11.3%, as compared with 1.3% for nonsevere disease (p = 0.008). The ATS severity criteria are valid in HIV-infected patients with bacterial CAP. Our study provides the basis for identification of patients who may require hospitalization determined by clinical judgment and the five clinical criteria of shock, a CD4(+) cell count < 100/microl, pleural effusion, cavities, and multilobar involvement. These prognostic factors should be validated in independent cohort studies.

    The aim of this study was to investigate the relationship between metabolic syndrome (MetS) and acquired premature ejaculation (PE). A total of 100 patients with acquired PE and 100 control cases were enrolled in the study. After obtaining a detailed medical history, anthropometric (weight, height and waist circumference) and blood pressure measurements were performed. Ejaculation and erection functions were evaluated by Premature Ejaculation Diagnostic Tool (PEDT) and International Index of Erectile Function-5 (IIEF-5), respectively. Self-estimated intravaginal ejaculatory latency time (IELT) of the participants was recorded. Fasting blood samples were taken for biochemical and hormonal work-up. The median PEDT scores were 16 (9-22) and 4.5 (2-8) in acquired PE and control groups, respectively (P<0.001). The mean estimated IELT values in PE patients and controls were 36.1±46.5  versus 488.2±313.8 s (P<0.001). MetS was diagnosed in 51 patients (51%) in the PE group and 24 (24%) participants in the control group (P<0.001). A significant negative correlation was observed between the components of MetS and estimated IELT, except for diastolic blood pressure. Moreover, there was a significant positive correlation between the all components of MetS and total PEDT score, except for fasting blood glucose and high-density lipoprotein cholesterol (HDL) levels. Logistic regression analysis revealed that, except blood pressure and HDL levels, MetS components were significant risk factors for PE after adjusting for age and total testosterone. In conclusion, MetS is associated with acquired PE.International Journal of Impotence Research advance online publication, 9 February 2017; doi:10.1038/ijir.2017.3.

    Asymptomatic hemophilia patients receiving Factor VIII concentrate were found to have normal natural killer (NK) cells and B cells, and an inverted T helper/suppressor ratio due to an increase in cells of T suppressor phenotype. In contrast, a hemophilia patient with acquired immune deficiency syndrome (AIDS) exhibited nonfunctional NK cells, low B cells, and an inverted T helper/suppressor ratio due to very low numbers of T helper cells. Hemophilia patients on cryoprecipitate therapy exhibited normal immune parameters. A high percentage of hemophilia patients on both treatments had antibody to hepatitis B virus. The isolated finding of elevated levels of T suppressor cells in hemophilia patients receiving Factor VIII concentrate has not been recognized as an early indicator of impending AIDS, and longitudinal studies will be required to determine its clinical significance.

    The livers of 26 adult males with acquired immune deficiency syndrome (AIDS) were reviewed. The occurrence of portal tracts with diminished lymphocytes, probably reflecting generalized exhaustion of the lymphoid system, was a characteristic morphologic change, and was found in all cases. Kupffer cell hyperplasia was also a frequent finding and probably reflected generalized infection(s). Punched-out clusters of foamy histiocytes filled with acid-fast bacilli, typical for infection with Mycobacterium avium intracellulare (MAC), were found in three patients. In addition, MAC was cultured from two livers without the foamy histiocytic changes. Chronic viral hepatitis (three cases) and deposition of polarizable materials (one case) in the liver might be related to unusual habits of patients with AIDS. In conclusion, livers from patients with AIDS disclosed several kinds of lesions reflecting underlying or associated conditions in AIDS, but these did not contribute to the cause of death in our patients.

    Autopsy and liver biopsy specimens from 30 pediatric patients with acquired immune deficiency syndrome (AIDS) or AIDS-related complex (ARC) were retrospectively reviewed. Of 28 cases with histologic abnormalities, the following findings were noted singly or in combination: giant-cell transformation, cytomegalovirus inclusions, Kaposi's sarcoma, diffuse lymphoplasmocytic infiltrate, granulomatous hepatitis, mild portal inflammation, necrosis around central veins, steatosis, and cholestasis. For the most part, abnormalities in the liver were not predictive of those in other organs, but the two children with the diffuse parenchymal lymphoplasmocytic infiltrate also had lymphoid interstitial pneumonitis (LIP). Liver histopathology in pediatric patients with AIDS shares some features with that in adults, but appreciable differences are noted. In particular, these differences include the higher frequency of giant-cell transformation and the lower frequency of granulomas in children and the observation of diffuse lymphoplasmocytic infiltrate associated with LIP.

    Earlier reported findings of hepatitis B virus (HBV) DNA in white blood cells of patients with hepatoma, and in a patient with autoimmune haemolytic anaemia, led to the examination of HBV DNA in a series of twenty three patients with acquired immune deficiency syndrome (AIDS), including nine with opportunistic infections and fourteen with Kaposi's sarcoma, by Southern blot hybridization method, using 32P labelled HBV DNA specific probe obtained by nick translation of HBV DNA cloned into plasmid pBR325. Four of the patients were found to be positive for HBV DNA or HBV related DNA in their leucocytes. The HBV DNA was found free or integrated in the leucocytes of the patients.

    The published data concerning changes of antithrombin III (ATIII) in nephrotic syndrome (NS) are contradictory. While increased ATIII activity has been reported by some investigators, decreased concentration has been shown by others and normal values by yet another group of authors. We determined plasma and urine concentrations of ATIII in a group of 20 patients with NS using an immunologic assay. In addition, plasma ATIII activity was determined. The results were compared with those obtained in a group of normal volunteers. Plasma concentration and activity of ATIII were both greatly reduced in the patients with NS. In addition, substantial quantities of ATIII were recovered in the urine of all tested patients. The present study, therefore, substantiates the low plasma concentrations of ATIII and its urinary losses in NS. In addition, a parallel reduction in plasma ATIII activity is demonstrated providing functional evidence of acquired ATIII deficiency in this condition.

    This study investigated the social capital of Iranian patients living with acquired immune deficiency syndrome (AIDS) and the associated factors. In a cross-sectional study the Integrated Social Capital Questionnaire was filled by a sequential sample of 300 patients visiting a referral counselling centre in Tehran. The patients' social capital scores were around 50% in the trust, social cohesion, collective action and cooperation and political empowerment domains. The groups and networks membership domain scored the lowest (27.1%). In regression analysis, employment status was significantly associated with groups and networks membership; age, marital status and financial status were associated with collective action and cooperation; period of disease awareness and marital status affected social cohesion and inclusion; and having risky behaviour affected empowerment and political action. Efforts are needed to enhance the social capital of those patients living with AIDS who are younger, unemployed, divorced/widowed, with risky behaviours and shorter disease awareness.

    Thirteen of 40 patients with acquired immune deficiency syndrome (AIDS) admitted to the wards of a large city hospital were seen by the staff of a psychiatric consultation service. Eleven were gay men and two were bisexual men. "Depression" was the stated reason for referral of 10 patients; of these, two met DSM-III criteria for major depression, one had dysthymic disorder, and seven had adjustment disorder with depressed mood. Recurrent psychological themes of the 13 patients were: dealing with a life-threatening illness, uncertainty about the implications of an AIDS diagnosis, social isolation, and guilt over their previous life style. The role of the primary physician and of the mental health professional in the psychological care of AIDS patients is discussed.

    Human immunodeficiency virus (HIV) affects all organ systems. Infection of the heart can manifest with evidence of myocarditis, pericarditis, or cardiomyopathy. The most common gastrointestinal symptom is diarrhea, which can result from infection with a variety of bacterial, fungal, or protozoal organisms. In about 15% of cases, no pathogen is recognized and the diarrhea syndrome is termed AIDS enteropathy. Any portion of the alimentary tract can be affected as well as the liver, gallbladder, and pancreas. Cryptosporidium, a previously infrequent cause of human illness, has emerged as an important pathogen in the HIV-infected patient and is responsible for chronic diarrhea, cholecystitis, and biliary tract obstruction. Evidence of neurologic involvement is present in more than 80% of patients at the time of autopsy. Cryptococcal meningitis, toxoplasma encephalitis, and neurosyphilis are the most often encountered central nervous system infections. While all three are responsive to therapy, treatment must be prolonged or persist for the duration of the patient's life to avoid recurrence. Peripheral nervous system manifestations include myelopathy, myopathy, and a variety of peripheral neuropathies. Retinal infection with cytomegalovirus (CMV) and toxoplasma can lead to irreversible loss of vision. Cotton wool spots are a common benign physical finding that must be differentiated from the early signs of CMV or toxoplasma infection. Management of the HIV-infected patient, while most often conducted by specialists in Internal Medicine or Infectious Diseases, is often an issue for the emergency physician. Many of the commonly afforded therapies are reviewed. Part 1 of this two-part series discussed the pathophysiology and clinical expression, epidemiology, laboratory testing, and the general clinical manifestations of AIDS, as well as dermatologic, pulmonary, and cardiac symptoms. Part 2 discusses the gastrointestinal, neurologic, and ocular symptoms, as well as the

    We herein present the case of a 55-year-old woman with a previous history of malignancies – uterine adenocarcinoma, basal cell carcinoma (which occurred twice consecutively), recurrent respiratory infections due to common variable immunodeficiency (CVID), and systemic granulomatous disease diagnosed at a later age. The patient suffered from diffuse large B cell lymphoma (DLBCL), which was successfully treated with R-CHOP chemotherapy, and continued with immunoglobulin supplementation. The patient was free of lymphoma and infectious complications for over 20 months despite her persistent immunodeficiency, but eventually developed colorectal adenocarcinoma. To the best of our knowledge, this is the first reported case of CVID associated with multiple solid tumours and DLBCL. PMID:25631905

    Listeria monocytogenes bacteremia without meningitis has been reported in patients who have undergone long-term hemodialysis and have transfusional iron overload. On the other hand, cases of Listeria bacteremia without meningitis have occurred sporadically among the acquired immunodeficiency syndrome population, mostly homosexuals. There have been no reports of Listeria meningitis occurring among persons who are antibody positive to human immunodeficiency virus or are intravenous drug abusers having chronic renal failure and undergoing hemodialysis. This patient represents the first case of Listeria bacteremia and meningitis to occur in an intravenous drug abuser who is human immunodeficient antibody positive, is receiving hemodialysis, and has transfusional iron overload.

    Mutations in the dedicator of cytokinesis 8 (DOCK8) gene cause a combined immunodeficiency usually diagnosed as autosomal recessive hyper IgE syndrome. We sought to reveal the varying manifestations in patients with a unique mutation in DOCK8 gene by a retrospective medical record review. Ten patients from five consanguineous families and three tribes were included. Seven patients were homozygous for the c.C5134A, p.S1711X mutation, and the remaining three patients were their siblings manifesting hyper IgE syndrome features without a genetic diagnosis. Prior to the genetic diagnosis, the clinical diagnosis was "hyper IgE syndrome" in six patients and "anti-pneumococcal antibody deficiency," "recurrent pneumonia with bronchiectasis," and "asthma with hypereosinophilic syndrome" each diagnosed once. One additional patient was diagnosed due to family history. The age of presentation varied from 1 to 16 months. Eczema was diagnosed in all patients, food allergies in three, and severe herpes keratitis or malignancy or autoimmunity in two patients. Elevated IgE was recorded in nine patients; however, in six patients, the initial serum IgE concentration was equal to or less than three times the normal concentration for age, and in these patients, the median age at IgE evaluation was 7.5 months compared with 21.5 months in patients with an initial IgE concentration above three times the normal concentration for age (P = 0.067). The spectrum of disease manifestations in patients with a unique mutation in DOCK8 is variable. The genotype-phenotype correlations may be modified by genetic and/or epigenetic modifiers beyond the monogenic effect. Younger patients tend to have lower IgE concentrations at the initial measurement of IgE.

    A human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) intervention using indigenous outreach workers was implemented with Hispanic injection drug users (IDUs) and their sexual partners in three locations: Laredo, Texas; San Diego, California; and San Juan, Puerto Rico. A total of 2,169 subjects were contacted, given health education, HIV antibody testing, and follow-up counseling. This article reports on the 1,616 IDUs (75%) who completed the initial and follow-up interviews. The results indicated significant increases in health knowledge on AIDS, decreases in needle risk drug taking behaviors, some decreases in sex risk behaviors, and more realistic perceptions of personal AIDS risk. Using multivariate analyses, gender (male) and increasing age (older than age 25 years) were the strongest predictors of behavior change. Surprisingly, the identification of a positive HIV serostatus was not a significant predictor of behavior change. Although intended as a comparison study between contrasting levels of intervention, logistical and administrative problems undermined the use of a true quasi-experimental design. Nonetheless, the results from this research suggest that the use of indigenous outreach workers is an effective means of combatting the spread of HIV in this difficult to reach population. Some programmatic recommendations are provided for future efforts of this kind, particularly in relation to role conflicts experienced by outreach workers.

    Background. Syndrome-specific interventions are a recommended approach to antibiotic stewardship, but additional data are needed to understand their potential impact. We implemented an intervention to improve the management of inpatient community-acquired pneumonia (CAP) and evaluated its effects on antibiotic and resource utilization. Methods. A stakeholder group developed and implemented a clinical practice guideline and order set for inpatient, non-intensive care unit CAP recommending a short course (5 days) of a fluoroquinolone-sparing antibiotic regimen in uncomplicated cases. Unless there was suspicion for complications or resistant pathogens, chest computed tomography (CT) and sputum cultures were discouraged. This was a retrospective preintervention postintervention study of patients hospitalized for CAP before (April 15, 2008–May 31, 2009) and after (July 1, 2011–July 31, 2012) implementation of the guideline. The primary comparison was the difference in duration of therapy during the baseline and intervention periods. Secondary outcomes included changes in use of levofloxacin, CT scans, and sputum culture. Results. One hundred sixty-six and 84 cases during the baseline and intervention periods, respectively, were included. From the baseline to intervention period, the median duration of therapy decreased from 10 to 7 days (P < .0001). Prescription of levofloxacin at discharge decreased from 60% to 27% of cases (P < .0001). Use of chest CT and sputum culture decreased from 47% to 32% of cases (P = .02) and 51% to 31% of cases (P = .03), respectively. The frequency of clinical failure between the 2 periods was similar. Conclusions. A syndrome-specific intervention for inpatient CAP was associated with shorter treatment durations and reductions in use of fluoroquinolones and low-yield diagnostic tests.

    Infection with parainfluenza virus typically produces a mild, self-limited upper respiratory infection. However, parainfluenza infections have become increasingly recognized as a source of severe morbidity and mortality in immunocompromised patients. In this retrospective study we identified 6 patients with congenital immunodeficiency and positive respiratory cultures for parainfluenza virus who died and underwent complete autopsy. Tissues obtained at autopsy were studied using hematoxylin and eosin-stained sections, immunoperoxidase staining for parainfluenza virus, and in selected cases, electron microscopy. All 6 patients exhibited typical cytopathic effects of parainfluenza virus, including giant cell formation, in lung and/or bronchial tissues. Parainfluenza virus infection was also documented by giant cell formation and immunohistochemistry in the pancreas (in 3 of 6 patients) and the kidney or bladder (in 2 of 4 patients). Anti-parainfluenza antibody also specifically reacted with cells in the gastrointestinal tract (in 2 of 4), spleen (in 4 of 6), thymus and/or lymph nodes (in 4 of 4), and small blood vessels in various organs (in 4 of 6). Pancreatic, bladder, colon, and thymic epithelial cell lines were susceptible to experimental infections with clinical isolates of parainfluenza virus type 3 in vitro. Parainfluenza virus infection was serious in patients with congenital immunodeficiencies, contributing directly to death in 5 of the 6 patients studied. Because this virus is capable of infecting tissues in the gastrointestinal and urinary systems as well as in the respiratory tract, body secretions and fluids from each of these locations should be considered potentially infectious.

    A retrospective review of 48 liver biopsies in 34 patients with acquired immune deficiency syndrome (AIDS) and 10 patients with AIDS-related complex (ARC) was performed at Harlem Hospital Center to assess the diagnostic yield of liver biopsies in this distinct patient population. Among the patients, 93.2% were black and 32 were males, with a mean age of 36.7 yr. Intravenous drug abuse was a risk factor for AIDS in 81.8% of patients. Liver biopsies were particularly useful in patients with fever of unclear origin, which was positively correlated with the presence of granulomas (p = 0.01). Granulomas due to mycobacteria were present in 16 (33.3%) of the biopsies. Liver biopsy proved to be clinically significant in 14 of 17 patients (82.3%) with mycobacterial disease, or 29.3% of the liver biopsies. Chronic active hepatitis was present in 12 (29.2%) of the biopsies, and in all but one was due to non-A non-B hepatitis viruses. All patients with chronic active hepatitis were intravenous drug abusers or the sexual partners of intravenous drug abusers. Liver biopsy can provide important diagnostic information in AIDS patients. The pathological findings in this series reflect the high risk of exposure to tuberculosis and hepatitis in the intravenous drug abusers in Harlem.

    Clinical data and histologic sections of the liver, including immunohistochemical studies for hepatitis B surface and core antigens, were reviewed in 42 autopsy cases of the acquired immune deficiency syndrome (AIDS). Hepatomegaly, elevation of serum transaminases, and mild elevation of alkaline phosphatase were commonly observed clinical and biochemical abnormalities. Mildly elevated alkaline phosphatase and normal bilirubin levels were present in patients with Mycobacterium avium-intracellulare (MAI) infection, cytomegalovirus (CMV) infection, and Kaposi's sarcoma (KS). Histologic sections demonstrated liver involvement by MAI in eight cases; KS in six cases; cryptococcus in three cases; and CMV in two cases. One case of MAI infection was associated with marked central vein sclerosis, a finding previously unreported. Thirty-two (76%) of 42 cases had serologic or pathologic evidence of hepatitis exposure. Two patients had histologic evidence of chronic active hepatitis. The pathologic processes involving the liver appeared to be secondary to the infections and neoplasms for which this population is susceptible and did not significantly contribute to morbidity or mortality. No findings specific or pathognomic for AIDS were identified in the liver.

    Abstract Objective: to identify the predictive factors for the nursing diagnoses in people living with Acquired Immune Deficiency Syndrome. Method: a cross-sectional study, undertaken with 113 people living with AIDS. The data were collected using an interview script and physical examination. Logistic regression was used for the data analysis, considering a level of significance of 10%. Results: the predictive factors identified were: for the nursing diagnosis of knowledge deficit-inadequate following of instructions and verbalization of the problem; for the nursing diagnosis of failure to adhere - years of study, behavior indicative of failure to adhere, participation in the treatment and forgetfulness; for the nursing diagnosis of sexual dysfunction - family income, reduced frequency of sexual practice, perceived deficit in sexual desire, perceived limitations imposed by the disease and altered body function. Conclusion: the predictive factors for these nursing diagnoses involved sociodemographic and clinical characteristics, defining characteristics, and related factors, which must be taken into consideration during the assistance provided by the nurse.

    Invasive fungal infections (IFIs) have become a major cause of morbidity and mortality among people with acquired immune deficiency syndrome (AIDS), however, little is known about the clinical features and prognosis of IFI in AIDS in China. This study aimed to characterise the clinical features and prognosis of IFI in AIDS patients in China. We retrospectively reviewed the records of all HIV-infected patients at a Chinese university hospital between December 2004 and May 2006. We identified 35 patients with IFI. IFIs included thrush, oesophageal candidiasis, fungal pneumonia, cryptococcosis, penicilliosis and fungaemia, 44.4% of IFIs occurred in the digestive tract, 71.8% of IFIs occurred in patients with CD4(+)T-lymphocyte counts <100 cells mm(-3). Candida albicans accounted for 57.4% of fungal pathogens isolated. All the patients received both antiretroviral and antifungal therapy; 27 patients were cured and eight died. IFI is one of the most common opportunistic infections in AIDS patients in China. IFIs mainly occur in patients with low CD4(+)T-lymphocyte counts. The majority of IFIs occur in the digestive tract. The most common pathogen causing IFI is C. albicans. The mortality rate remains high although antiretroviral therapy and many newer antifungals are available in China.

    84 year old male with past medical history of myelodysplastic syndrome (MDS) presented with progressive subcutaneous and muscle bleed in the right forearm and arm. Workup revealed elevated activated partial thromboplastin time (aPTT) - 71.8 seconds (normal 23 - 32 seconds) which was persistently elevated after mixing study (37.1 seconds immediately and 51.1 seconds after 1 hour). Further laboratory work up revealed low factor VIII level (3%) and elevated factor VIII inhibitor by Bethesda assay (3 units/ml of blood). Acquired hemophilia A (AHA) diagnosis was established and patient was treated with recombinant factor VIIa (rFVlla) to control the bleeding and also prednisone for immunosuppression. Subsequent monitoring suggested reduction of factor VIII inhibitor - antibody levels to undetectable level in 3 days and increase of factor VIII level from 3% to 50% in 5 days. Despite of improvement in the laboratory values he continued to have progression of his bleeding which involved posterior chest wall and also left arm. Due to the progression of the condition and prior expressed wish family decided to stop the aggressive treatment and patient died nine days after the diagnosis. The case report describes a rare presentation of AHA in MDS (With bone marrow cytogenetics abnormality) patient with fatal outcome. PMID:22837802

    Low T3 syndrome was previously reported to be linked to poor clinical outcomes in critically ill patients. The aim of this study was to evaluate the predictive power of low T3 syndrome for clinical outcomes in patients with community-acquired pneumonia (CAP). Data for 503 patients were analyzed retrospectively, and the primary end point was 30-day mortality. The intensive care unit (ICU) admission rate and 30-day mortality were 8.3% and 6.4% respectively. The prevalence of low T3 syndrome differed significantly between survivors and nonsurvivors (29.1% vs 71.9%, P < 0.001), and low T3 syndrome was associated with a remarkable increased risk of 30-day mortality and ICU admission in patients with severe CAP. Multivariate logistic regression analysis produced an odds ratio of 2.96 (95% CI 1.14–7.76, P = 0.025) for 30-day mortality in CAP patients with low T3 syndrome. Survival analysis revealed that the survival rate among CAP patients with low T3 syndrome was lower than that in the control group (P < 0.01). Adding low T3 syndrome to the PSI and CURB-65 significantly increased the areas under the ROC curves for predicting ICU admission and 30-day mortality. In conclusion, low T3 syndrome is an independent risk factor for 30-day mortality in CAP patients. PMID:26928863

    2011-10-15

    Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) are retroviruses with a global impact on the health of domestic cats. The two viruses differ in their potential to cause disease. FIV can cause an acquired immunodeficiency syndrome that increases the risk of developing opportunistic infections, neurological diseases, and tumors. In most naturally infected cats, however, FIV itself does not cause severe clinical signs, and FIV-infected cats may live many years without any health problems. FeLV is more pathogenic, and was long considered to be responsible for more clinical syndromes than any other agent in cats. FeLV can cause tumors (mainly lymphoma), bone marrow suppression syndromes (mainly anemia) and lead to secondary infectious diseases caused by suppressive effects of the virus on bone marrow and the immune system. Today, FeLV is less important as a deadly infectious agent as in the last 20 years prevalence has been decreasing in most countries.

    2010-03-01

    There seems to be an association between type 1 Chiari malformation (CM) and some congenital craniosynostosis syndromes. Type 2 Pfeiffer syndrome is a condition associated with premature fusion of multiple cranial sutures, cloverleaf skull (kleeblatschädel deformity), prominent ptosis, thumb and first toe abnormalities, variable syndactyly, and mutated genes for type 1 or 2 fibroblast growth factor receptor. These children generally do poorly because of significant often severe neurologic and cognitive defects, and many die very young. Roughly half of all patients with Pfeiffer syndrome, and virtually all with type 2 disease, also have type 1 CM. Chiari malformation may not be congenital but acquired as a consequence of the skull deformities and other associated intracranial factors in patients with craniosynostosis. We report a term male infant with type 2 Pfeiffer syndrome, who was not noted to have any CM on initial brain imaging done at 2 months but in whom repeated imaging demonstrated clear evidence of CM by 4 months, despite reconstructive craniotomies and unilateral ventriculoperitoneal shunt insertion. Posterior fossa decompression yielded a good result. This patient provides further evidence to support the concept of acquired tonsillar herniation in patients with craniosynostosis syndromes. The etiology seems multifactorial and related to (1) the disproportionately slow growth of the skull relative to the brain, particularly in the posterior fossa, secondary to early fusion of skull sutures, in turn secondary to congenital deficiencies in fibroblast growth factor receptors; (2) impaired venous sinus drainage; (3) hydrocephalus; and (4) resultant elevations in intracranial pressure.

    Effective antiretroviral therapy leads to rapid decrease in plasma HIV-1 RNA, frequently followed by an increase in CD4 T-helper cell counts. The improvement of immune function during highly active antiretroviral therapy has important impact on natural history of AIDS-related opportunistic disorders. Here we describe cases of unusual clinical inflammatory syndromes in CMV retinitis, hepatitis C, and atypical mycobacteriosis in HIV-1 infected patients associated with the initiation of antiretroviral therapy. Pathogenetic implications and therapeutic management of these new immunopathologic syndromes are discussed.

    The number of surveillance networks for infectious disease diagnosis and response has been growing. In 2000, the World Health Organization (WHO) established the Global Outbreak Alert and Response Network, which has been endorsed by each of the 46 WHO African members since then. Yet, taming the dynamics and plague of the vicious Ebola virus disease (EVD) in African countries has been patchy and erratic due to inadequate surveillance and contact tracing, community defiance and resistance, a lack of detection and response systems, meager/weak knowledge and information on the disease, inadequacies in protective materials protocols, contact tracing nightmare and differing priorities at various levels of the public health system. Despite the widespread acceptance of syndromic surveillance (SS) systems, their ability to provide early warning alerts and notifications of outbreaks is still unverified. Information is often too limited for any outbreak, or emerging or otherwise unexpected disease, to be recognized at either the community or the national level. Indeed, little is known about the role and the interactions between the Ebola infection and exposure to other syndemics and the development of acquired immunity, asymptomatic reservoir, and Ebola seroconversion. Can lessons be learnt from smallpox, polio, and influenza immunity, and can immunization against these serve as a guide? In most endemic countries, community health centers and disease control and prevention at airports solely relies on passive routine immunization control and reactive syndromic response. The frontline and airport Ebola SS systems in West Africa have shown deficiencies in terms of responding with an alarming number of case fatalities, and suggest that more detailed insights into Ebola, and proactive actions, are needed. The quest for effective early indicators (EEE) in shifting the public and global health paradigm requires the development and implementation of a comprehensive and effective

    The acquired immune deficiency syndrome (AIDS) occurs most commonly in homosexual men. This group carries the greatest risk of transmitting AIDS by blood transfusion. Both promiscuous and nonpromiscuous male homosexuals should refrain from giving blood. A leaflet stating this advice was prepared by the Department of Health and Social Security, United Kingdom. In July 1984 a questionnaire was given to all donors attending a blood donor clinic in the west end of London, England. 53% were male. Donors were given a leaflet on AIDS and a questionnaire to complete in private. Those who considered themselves to be in a high risk group were asked to designate their blood for research purposes only. Serum samples from donors who confirmed that they were in the high risk category were tested for antihepatitis B core antigen and anti-human T lymphotropic virus type III (anti-HTLV-III) in addition to the routine screening of donors for hepatitis B surface antigen and syphilis. All high risk donors were men. Homosexuality was the only high risk factor. Of 5000 questionnaires administered between July and October, 614 were not completed or had ambiguous answers. 38 donors who completed the questionnaire beonged to a high risk group. Of these, 7 were positive for antihepatitis B core antigen; none were positive for anti-HTLV-III, T pallidum hemagglatination, or hepatits B surface antigen. Although the homosexual donors had a much lower incidence of sexually transmitted disease than those attending special clinics, this should not encourage complacency. All possible measures must be taken to prevent homosexuals from donating blood.

    Because of reports that acquired immune deficiency syndrome (AIDS) might be transmissible by blood transfusion, we studied potential surrogate tests that could be used for screening donors. Male donors at one volunteer blood center and two plasma centers were screened for total lymphocyte count, OKT3, OKT4, OKT8, OKT11, LEU-7, LEU-M2, antibodies to hepatitis B core (anti-HBc), cytomegalovirus (CMV), and herpes and circulating immune complexes. Total lymphocyte counts and the OKT11 were significantly lower in one plasma center. No significant differences were found for the other lymphocyte or monocyte tests. Low T4/T8 ratios, found in 20 percent of donors, did not correlate with other abnormalities. A small percentage (3.3%) of volunteer donors, 15.4 percent at one plasma center and 20.8 percent at a second plasma center, and 38.5 percent of the male homosexual donors were positive for anti-HBc (significant when comparing the male homosexuals to the volunteers at p = 0.032). Positive CMV and herpes titers were similar in the groups. Circulating immune complex levels greater than two standard deviations above the mean were found in 20 percent of the volunteer donors, 7.7 percent at one plasma center and 8.3 percent at the second plasma center, and none in the male homosexual population. Pearson product moment correlations showed reasonably good agreement among the lymphocyte tests. However, the anti-HBc, CMV, and herpes antibodies and circulating immune complex levels did not correlate with any of the other tests. Surrogate tests for AIDS are nonspecific and unlikely to be helpful in screening blood donor units.

    Despite great improvements in preventing and treating sexually transmitted diseases (STDs) and reproductive tract infections (RTIs), including HIV/AIDS, infections have been increasing significantly throughout the world. The problem of STDs, RTIs, and HIV/AIDS among women aged 15-49 years is increasing at an alarming rate. Certain biological risk factors and cultural practices enhance the vulnerability of women of reproductive age. Among these biological risks are age, gender, blood transfusion during pregnancy and childbirth, and the development of asymptomatic STDs/RTIs. These are exacerbated by cultural practices like douching with pharmaceutical products, use of intravaginal substances, and the practice of anal sex. STDs, RTIs, and HIV/AIDS affect female reproductive health in certain ways: mother-to-child transmission, effects on pregnancy (spontaneous abortion, premature birth, stillbirth, low birth weight, ectopic pregnancy), infertility, cancer, and rise in AIDS-related mortality. On the other hand, society will experience an increase in orphans, destabilization of the family unit, and a reduction in family income. Considering the impact of these diseases on the reproductive health of women and the community, measures should be taken to prevent and control the epidemic. The paper discusses certain interventions and diagnostic and preventive strategies against STDs, RTIs, and HIV/AIDS.

    The authors make out a statement about HIV infection in French Polynesia at the date of 1991 December 31. 96 cases all together of seropositive and AIDS infected people were recorded. These patients are young generally (78 p.c. between 21 and 40 years old) sexually contaminated (72 out of 96) and live in Tahiti island (94 p.c.). Sex-ratio is 2.8 male/1 female. Among them, we noted 55 p.c. of Europeans, 38 p.c. of Polynesians and 7 p.c. of Asiatic people. Epidemiological monitoring of the infection was made easy because of a set of laws and possibilities of detection highly favourable. Progress of the infection is constant, with 20 new cases detected each year with a prevalence of 150 cases of AIDS per 1 million of inhabitants, French Polynesia could be classified as the 5th or 6th region of France as far as the importance of the disease. Clinical, biological and epidemiological taking of charge of patients is detailed as well as the prevention campaign.

  8. Computer simulations of the interaction of human immunodeficiency virus (HIV) aspartic protease with spherical gold nanoparticles: implications in acquired immunodeficiency syndrome (AIDS)

    The interaction of gold nanoparticles (AuNP) with human immune-deficiency virus aspartic protease (HIVPR) is modelled using a regime of molecular dynamics simulations. The simulations of the ‘docking’, first as a rigid-body complex, and eventually through flexible-fit analysis, creates 36 different complexes from four initial orientations of the nanoparticle strategically positioned around the surface of the enzyme. The structural deviations of the enzymes from the initial x-ray crystal structure during each docking simulation are assessed by comparative analysis of secondary structural elements, root mean square deviations, B-factors, interactive bonding energies, dihedral angles, radius of gyration (R g), circular dichroism (CD), volume occupied by C α , electrostatic potentials, solvation energies and hydrophobicities. Normalisation of the data narrows the selection from the initial 36 to one ‘final’ probable structure. It is concluded that, after computer simulations on each of the 36 initial complexes incorporating the 12 different biophysical techniques, the top five complexes are the same no matter which technique is explored. The significance of the present work is an expansion of an earlier study on the molecular dynamic simulation for the interaction of HIVPR with silver nanoparticles. This work is supported by experimental evidence since the initial ‘orientation’ of the AgNP with the enzyme is the same as the ‘final’ AuNP-HIVPR complex generated in the present study. The findings will provide insight into the forces of the binding of the HIVPR to AuNP. It is anticipated that the protocol developed in this study will act as a standard process for the interaction of any nanoparticle with any biomedical target.

    Background.  Pediatric Kawasaki disease (KD) and human immunodeficiency virus (HIV)(+) adult Kawasaki-like syndrome (KLS) are dramatic vasculitides with similar physical findings. Both syndromes include unusual arterial histopathology with immunoglobulin (Ig)A(+) plasma cells, and both impressively respond to pooled Ig therapy. Their distinctive presentations, histopathology, and therapeutic response suggest a common etiology. Because blood is in immediate contact with inflamed arteries, we investigated whether KD and KLS share an inflammatory signature in serum. Methods.  A custom multiplex enzyme-linked immunosorbent assay (ELISA) defined the serum cytokine milieu in 2 adults with KLS during acute and convalescent phases, with asymptomatic HIV(+) subjects not taking antiretroviral therapy serving as controls. We then prospectively collected serum and plasma samples from children hospitalized with KD, unrelated febrile illnesses, and noninfectious conditions, analyzing them with a custom multiplex ELISA based on the KLS data. Results.  Patients with KLS and KD subjects shared an inflammatory signature including acute-phase reactants reflecting tumor necrosis factor (TNF)-α biologic activity (soluble TNF receptor I/II) and endothelial/smooth muscle chemokines Ccl1 (Th2), Ccl2 (vascular inflammation), and Cxcl11 (plasma cell recruitment). Ccl1 was specifically elevated in KD versus febrile controls, suggesting a unique relationship between Ccl1 and KD/KLS pathogenesis. Conclusions.  This study defines a KD/KLS inflammatory signature mirroring a dysfunctional response likely to a common etiologic agent. The KD/KLS inflammatory signature based on elevated acute-phase reactants and specific endothelial/smooth muscle chemokines was able to identify KD subjects versus febrile controls, and it may serve as a practicable diagnostic test for KD.

    Poliovirus transmission has been eliminated in most of the world through the use of inactivated poliovirus vaccine (IPV) and live, attenuated oral poliovirus vaccine (OPV). In the United States, use of OPV was discontinued by the year 2000 because of the potential for vaccine-associated paralytic polio (VAPP); an average of eight cases were reported each year in the United States during 1980-2000. Polio eradication efforts in other parts of the world continue to rely on OPV to take advantage of transmission of poliovirus vaccine strains to unvaccinated persons in the population, lower cost, and ease of administration. In 2013, an infant aged 7 months who recently immigrated to the United States from India was referred to a hospital in San Antonio, Texas. The infant had fever, an enlarging skin lesion in the deltoid region with axillary lymphadenopathy, decreased activity, and inability to bear weight on the left leg, progressing to paralysis of the left leg over a 6-week period. Recognition of lymphopenia on complete blood count led to immune evaluation, which revealed the presence of severe combined immunodeficiency syndrome (SCIDS), an inherited disorder. A history of OPV and bacille Calmette-Guérin (BCG) vaccination in India led to the diagnoses of VAPP and BCG-osis, which were confirmed microbiologically. This report demonstrates the importance of obtaining a comprehensive clinical history in a child who has recently immigrated to the United States, with recognition that differing vaccine practices in other countries might require additional consideration of potential etiologies.

    The Chediak-Higashi syndrome (CHS) is a human recessive autosomal disease caused by mutations in a single gene encoding a protein of unknown function, called lysosomal-trafficking regulator. All cells in CHS patients bear enlarged lysosomes. In addition, T- and natural killer cell cytotoxicity is defective in these patients, causing severe immunodeficiencies. We have analyzed major histocompatibility complex class II functions and intracellular transport in Epstein Barr Virus–transformed B cells from CHS patients. Peptide loading onto major histocompatibility complex class II molecules and antigen presentation are strongly delayed these cells. A detailed electron microscopy analysis of endocytic compartments revealed that only lysosomal multilaminar compartments are enlarged (reaching 1–2 μm), whereas late multivesicular endosomes have normal size and morphology. In contrast to giant multilaminar compartments that bear most of the usual lysosomal markers in these cells (HLA-DR, HLA-DM, Lamp-1, CD63, etc.), multivesicular late endosomes displayed reduced levels of all these molecules, suggesting a defect in transport from the trans-Golgi network and/or early endosomes into late multivesicular endosomes. Further insight into a possible mechanism of this transport defect came from immunolocalizing the lysosomal trafficking regulator protein, as antibodies directed to a peptide from its COOH terminal domain decorated punctated structures partially aligned along microtubules. These results suggest that the product of the Lyst gene is required for sorting endosomal resident proteins into late multivesicular endosomes by a mechanism involving microtubules. PMID:9606205

    Juvenile polyposis syndrome (JPS) is a rare genetic disorder characterized by juvenile polyps of the gastrointestinal tract. We present a new pathogenic mutation of the SMAD4 gene and illustrate the need for a multidisciplinary health care approach to facilitate the correct diagnosis. The patient, a 47-year-old Caucasian woman, was diagnosed with anaemia at the age of 12. During the following 30 years, she developed numerous gastrointestinal polyps. The patient underwent several operations, and suffered chronic abdominal pain, malnutrition, and multiple infections. Screening of the SMAD4 gene revealed a novel, disease-causing mutation. In 2012, the patient suffered hypoalbuminemia and a large polyp in the small bowel was found. Gamma globulin was given but the patient responded with fever and influenza-like symptoms and refused more treatment. The patient underwent surgery in 2014 and made an uneventful recovery. At follow-up two months later albumin was 38 g/L and IgG was 6.9 g/L. Accurate diagnosis is essential for medical care. For patients with complex symptomatology, often with rare diseases, this is best provided by multidisciplinary teams including representatives from clinical genetics. Patients with a SMAD4 mutation should be followed up both for JPS and haemorrhagic hereditary telangiectasia and may develop protein loosing enteropathy and immunodeficiency. PMID:25705527

    The aim of this study was to investigate the causes of death among 129 AIDS patients that were autopsied at the Tropical Medicine Foundation of Amazonas between 1996 and 2003. The degree of concordance between the autopsy diagnoses and the clinical diagnoses was observed. The disease that most frequently caused death was tuberculosis (28%), followed by bacterial pneumonia (17%), histoplasmosis (13%), toxoplasmosis (10%), pneumocystosis (8%), cryptococcosis (5%), bacterial sepsis (4%) and other causes (15%). The concordance between the clinical diagnosis before death and the autopsy was 51.9%. The main organ involved was the lungs (82.2%). The length of survival from the time of the laboratory diagnosis to death ranged from one month to 120 months. The mean length of survival was 15 days and 56% died less than one month after the diagnosis, while 15 patients died on the same day that they were diagnosed. These results show the importance of autopsies in elucidating the causes of death among AIDS patients.

    In the current AIDS pandemics, equipping health professional students with adequate knowledge and positive attitude is necessary to produce graduates who can deliver appropriate intervention to patients infected with HIV or who have developed AIDS. The purpose of this study was 1) to investigate the Nigerian physiotherapy students' knowledge, attitude, and their willingness to provide care for patients living with AIDS (PWA) and to 2) determine the sociodemographic variables that could influence the students' attitude and willingness to provide care for PWA. Physiotherapy students (N = 104) in four training programs in Nigeria were surveyed using a two-part questionnaire. Part I elicited sociodemographic and previous AIDS encounter information, and Part II assessed knowledge, attitude, and willingness to provide care to PWA. Nigerian students showed unsatisfactory knowledge, harbored negative attitude, and many of them were unwilling to render care for PWA. Religious affiliation, training programs, long-term career goals, and previous instructions on AIDS influenced the students' attitude. The study identified the need for a comprehensive AIDS curriculum and recommend that all programs in Nigeria include clinical clerkship, small group discussions, and seminars on ethical and medico-legal issues on AIDS in their curriculum.

    In 1996, one hundred health histories of HIV serum positive patients were reviewed using the Elisa and Western Blot techniques at the Arzobispo Loayza National Hospital. Such cases were defined according to Case Definition 1987 CDC/WHO. 70% of HIV serum positive patients showed gastrointestinal symptoms according to the first medical examination. 57% of the patients were younger than 30 years old, most of them were men (men/ women ratio: 2.7/1). 59% of the patients were heterosexual, 26% bisexual, and 15% homosexual. Chronic diarrhea was the main symptom, characterized by watering depositions over 10c/d. Giardia lamblia was isolated in 32% of the cases, while Isospora Belli in 16% and Criptosporidium in 12.5%. The laboratory findings of 7 patients (12.5%) were negative. Patients showed more than 10% weight loss. 10% of the patients had an anorectal disease while 7 of the patients (10%) had an hepatic-billiary disease. The odynophagia and dysphagia were explained by oropharyngeal candidiasis. 2.8% of the patients had acalculous cholecystitis; 2.8% suffered from acute pancreatic disease and 1.4% ascitis. The hepatic biochemistry was affected by the serum albumin reduction, the transaminases increase over 2-3 times compared to normal levels and the alkaline phosphatase, bilirrubina was about 5 mg. The high endoscopic diagnostic was in connection to the candida esophagitis and inflammatory pathology. In proctoscopy, condyloma acuminatum and perianal fistula were the most usual findings. The counting of CD4 leukocytes in 20 patients showed a great reduction of CD4 lymphocytes, in values lesser than 200 cel/mm3. The relation CD4/CD8 goes from 0.01 to 0.91 rates.

    We performed a two-year cost of illness study of 240 AIDS patients (55 percent of all Massachusetts cases) diagnosed and treated at five hospitals from March 1984 through February 1986. Sociodemographic and clinical data as well as information on medical utilization were obtained from review of inpatient and outpatient hospital records. The yearly inpatient cost per patient decreased by 28 percent from $38,369 in year one to $27,714 in year two. These changes were related to shorter lengths of stay (from 20.6 days to 16.8 days per hospitalization, mean difference of 3.8 days, 95% CI of the difference -.2, 7.8), and less costly hospitalizations (from $12,463 to $9,957, mean difference of $2,506, 95% CI of the difference $135, $4,877). The probability of hospitalization, however, was similar in both years. These patterns of care were still evident after controlling for transmission category, race, site, mortality, insurance, age, gender, number and type of opportunistic diseases and time since diagnosis. Although the cost per patient per year decreased between years one and two, median survival increased by 70 percent (from 10 to 17 months). Hence overall estimated lifetime costs increased by 24 percent. PMID:2356908

    In the early 1980s, the World Health Organization (WHO) designated the Virology Unit of the Faculty of Medicine, Health Sciences Centre, Kuwait University, Kuwait, a collaborating centre for AIDS for the Eastern Mediterranean Regional Office (EMRO), recognizing it to be in compliance with WHO guidelines. In this centre, research integral to the efforts of WHO to combat AIDS is conducted. In addition to annual workshops and symposia, the centre is constantly updating and renewing its facilities and capabilities in keeping with current and latest advances in virology. As an example of the activities of the centre, the HIV-1 RNA viral load in plasma samples of HIV-1 patients is determined by real-time PCR using the AmpliPrep TaqMan HIV-1 test v2.0. HIV-1 drug resistance is determined by sequencing the reverse transcriptase and protease regions on the HIV-1 pol gene, using the TRUGENE HIV-1 Genotyping Assay on the OpenGene® DNA Sequencing System. HIV-1 subtypes are determined by sequencing the reverse transcriptase and protease regions on the HIV-1 pol gene using the genotyping assays described above. A fundamental program of Kuwait's WHO AIDS collaboration centre is the national project on the surveillance of drug resistance in human deficiency virus in Kuwait, which illustrates how the centre and its activities in Kuwait can serve the EMRO region of WHO.

    Negative and discriminatory attitudes towards people living with HIV/AIDS (PLWHA) are one of the biggest experienced challenges by people suffering from HIV, and these attitudes have been regarded as a serious threat to the fundamental rights of all infected people who are affected or associated with this disease in Iran. This study aimed to determine the relationship between public perception about HIV/AIDS and discriminatory attitudes toward PLWHA . The present study was conducted using a descriptive and survey design. Data were collected from 450 patients (236 male and 214 female) in Tehran and Yazd cities. The research instruments were modified HIV-related knowledge/attitude and perception questions about PLWHA, and discriminatory attitudes toward PLWHA. The results showed that prevalence of discriminatory attitudes toward PLWHA in the studied population was 60.0%. There was a significant negative correlation between citizens' awareness about HIV/AIDS, HIV-related attitudes, negative perception toward people with HIV/AIDS symptoms and their discriminatory attitudes toward PLWHA (p < .01). The hierarchical multiple regression analysis showed that components of public perception about HIV/AIDS explained for 23.7% of the variance of discriminatory attitudes toward PLWHA. Negative public perceptions about HIV/AIDS in Iran associated with discriminatory attitudes toward PLWHA and cultural beliefs in Iran tend to stigmatize and discriminate against the LWHA.

  2. Molecular analysis of T-B-NK+ severe combined immunodeficiency and Omenn syndrome cases in Saudi Arabia

    2009-01-01

    Background Children with Severe Combined Immunodeficiency (SCID) lack autologous T lymphocytes and present with multiple infections early in infancy. Omenn syndrome is characterized by the sole emergence of oligoclonal auto-reactive T lymphocytes, resulting in erythroderma and enteropathy. Omenn syndrome (OS) shares the genetic aetiology of T-B-NK+ SCID, with mutations in RAG1, RAG2, or DCLRE1C. Methods Patients diagnosed with T-B-NK+ SCID or phenotypes suggestive of Omenn syndrome were investigated by molecular genetic studies using gene tightly linked microsatellite markers followed by direct sequencing of the coding regions and splice sites of the respective candidate genes. Results We report the molecular genetic basis of T-B-NK+ SCID in 22 patients and of OS in seven patients all of Arab descent from Saudi Arabia. Among the SCID patients, six (from four families) displayed four homozygous missense mutations in RAG1 including V433M, R624H, R394W, and R559S. Another four patients (from three familes) showed 3 novel homozygous RAG2 mutations including K127X, S18X, and Q4X; all of which predict unique premature truncations of RAG2 protein. Among Omenn patients, four (from two families) have S401P and R396H mutations in RAG1, and a fifth patient has a novel I444M mutation in RAG2. Seven other patients (six SCID and one OS) showed a gross deletion in exons 1-3 in DCLRE1C. Altogether, mutations in RAG1/2 and DCLRE1C account for around 50% and 25%, respectively, in our study cohort, a proportion much higher than in previous reported series. Seven (24%) patients lack a known genetic aetiology, strongly suggesting that they carry mutations in novel genes associated with SCID and Omenn disorders that are yet to be discovered in the Saudi population. Conclusion Mutation-free patients who lack a known genetic aetiology are likely to carry mutations in the regulatory elements in the SCID-causing genes or in novel genes that are yet to be discovered. Our efforts are underway

    To assess the spectrum of hepatic abnormalities in acquired immune deficiency syndrome (AIDS), we reviewed clinical, biochemical, and pathological material in 32 patients with AIDS. Eight-four percent of AIDS cases had a history of intravenous drug abuse. Ninety percent of AIDS patients has some liver biochemical abnormality at the first presentation of illness. During the course of AIDS, significant (p less than 0.05, paired Student's t test) rises in alkaline phosphatase and bilirubin occurred, without rises in aminotransferases. Mean abnormalities were mild, reflecting approximately 2-fold increases over baseline. Liver failure was not believed to contribute to the death of any AIDS patient. Pathological findings in AIDS included specific infectious diagnosis in 26%, granulomas in 16%, hemosiderosis in 26%, nonspecific abnormalities in 39%, cirrhosis in 23%, and chronic active hepatitis in 3%. AIDS cases were also compared to 10 selected age, sex, and epidemiologically similar non-AIDS patients. Although granulomas or infections were not seen in our comparison group, only the incidence of chronic active hepatitis was significantly different between the groups. If only those with intravenous drug abuse were studied, then none of 24 AIDS patients versus four of eight non-AIDS cases (p less than 0.005) had chronic active hepatitis. AIDS patients with specific hepatic infections tended to have a higher alkaline phosphatase and aspartate aminotransferase (p less than 0.05) than noninfected cases. However, substantial overlap existed, and no difference in hepatomegaly was noted. Ninety percent of AIDS patients were ingesting at least one potentially hepatotoxic drug. We conclude that AIDS patients have a high incidence of underlying hepatic abnormalities. However, clinical and biochemical abnormalities are similar in our selected liver biopsy patients with intravenous drug abuse with or without AIDS. As expected, AIDS patients have a higher incidence of hepatic

    We report on 11 patients with 8 independent families (3 pairs of sibs) with a complex clinical pattern including microcephaly, peculiar {open_quotes}bird-like{close_quotes} face, growth retardation, and, in some cases, mild-to-moderate mental deficiency. Most of the patients have recurring respiratory tract infections. One girl has developed B-cell lymphoma. A detailed anthropometric study of 15 physical parameters, including 3 cephalic traits, was performed. It was possible to study the chromosomes of PHA-stimulated lymphocytes in all of the patients. We found structural aberrations with multiple rearrangements, preferentially involving chromosomes 7 and 14 in a proportion of metaphases in all individuals. Profound humoral and cellular immune defects were observed. Serum AFP levels were within normal range. Radioresistant DNA synthesis was strongly increased in all 8 patients who were hitherto studied in this respect.

    We describe a 34-year-old male patient with Jacobsen syndrome associated with a broad spectrum of anomalies and an increased susceptibility to infections. Features commonly seen in Jacobsen syndrome were short stature, mental retardation, congenital heart disease, cryptorchidism, strabismus, distal hypospadia glandis, and mild thrombocytopenia. Chromosome analysis disclosed a mosaic 46,XY,del(11)(q24.1)/46,XY karyotype with a very low percentage of normal cells. In addition, transverse upper limb defect, imperforate anus, and hearing impairment were noted. Cellular anomalies include functional impairment and deficiency of T-helper cells, and a low serum immunoglobulin M (IgM)-level. The presence of a transverse limb defect and primary immunodeficiency has not been reported previously in Jacobsen syndrome.

    A girl with 18q deletion syndrome was diagnosed with autoimmune diabetes mellitus and Hashimoto's thyroiditis at the age of 3 yr. In addition, the girl suffered from recurrent infections due to immunoglobulin A and IgG4 deficiency. She was also found to have CD3+CD4+FoxP3+, CD3+CD4+FoxP3+CD25+, and CD3+CD4+CD25+CD127 regulatory T cells deficiency. The exceptional coincidence of the two autoimmune disorders occurring at an early age, and associated with immune deficiency, implies that genes located on deleted 19.4 Mbp region at 18q21.32-q23 (chr18:58,660,699-78,012,870) might play a role in the pathogenesis of autoimmunity leading to β cell destruction and diabetes.

    Leukocyte adhesion deficiency (LAD) is characterized by the inability of leukocytes, in particular neutrophilic granulocytes, to emigrate from the bloodstream towards sites of inflammation. Infectious foci are nonpurulent and may eventually become necrotic because of abnormal wound healing. LAD-1 is characterized by the absence of the beta2 integrins (CD11/CD18) on leukocytes. When expression is completely absent, patients often die within the first year. However, low levels of beta2 expression may result in a milder clinical picture of recurrent infection, which offers a better prognosis. In this paper, we describe the in vivo and in vitro findings on a patient with clinical features of a mild LAD-1 disorder, i.e., suffering from bacterial infections without apparent pus formation in the presence of a striking granulocytosis, showing no delayed-type hypersensitivity reaction upon skin testing, no specific antibody generation, but normal in vitro T cell proliferation responses after immunization. Expression levels of CD11/CD18 proteins were completely normal, but leukocyte activation did not result in CD11/ CD18 activation and high-avidity ligand-binding. In vitro chemotaxis and endothelial transmigration of the neutrophils as well as leukocyte aggregation responses were almost absent. On the other hand, beta1 and beta3 integrin-mediated adhesion functions were completely normal. During follow-up, a bleeding tendency related to decreased beta3 activation became clinically apparent, different from previously described cellular adhesion molecule variants. Therefore, this is the first well-documented case of a clinical combined immunodeficiency syndrome that results from nonfunctional CD11/CD18 molecules, and thus designated LAD-1/ variant.

    In this study we present a patient with Loeffler's syndrome caused by Ascaris lumbricoides who presented with the clinical findings of community-acquired pneumonia (CAP). Our patient, who was twenty-five years old, and who had had symptoms such as coughing, expectorating, dyspnea and fever for approximately ten days, was hospitalized. We auscultated polyphonic rhonchuses at the both hemithoraxes. A chest X-ray revealed bilateral lower zone patch consolidation. Acute bacterial community acquired pneumonia (CAP) was diagnosed due to these findings and empirical antibiotic treatment was begun. Repeated sputum Gram stains were negative, and both sputum and blood cultures were sterile. A sputum smear was negative for acid-fast bacilli. The patient's fever and respiratory complaint did not respond to the empirical antibiotics therapy. During the course of advanced investigations, we measured peripheric eosinophilia, and high levels of total Eo and total IgE, and observed Ascaris lumbricoides eggs during stool examination. The patient was given a diagnosis of Loeffler's syndrome. Thereupon the patient was treated successfully with one dose of albendazol 400 mg. In conclusion, we suggest that Loeffler's syndrome must be considered early in the differential diagnosis for CAP when peripheric eosinophilia is seen in patients if they live in an endemic area for parasitic disease.

    Acquired Dyke-Davidoff-Masson syndrome, also known as hemispheric atrophy, is characterized by loss of volume of one cerebral hemisphere from an insult in early life. Crossed cerebellar diaschisis refers to dysfunction/atrophy of cerebellar hemisphere which is secondary to contralateral supratentorial insult. We describe magnetic resonance imaging findings in two cases of acquired Dyke-Davidoff-Masson syndrome with crossed cerebro-cerebellar diaschisis.

  10. Immunomodulation and immunodeficiency.

    PubMed

    Foster, Aiden P

    2004-04-01

    This article briefly reviews the concepts of immunodeficiency and immunomodulation as they relate to selected skin diseases in the dog and cat. Immunodeficiency states are uncommon and may be associated with a subnormal or down-regulated immune system, including humoral deficiencies, such as IgA, and abnormal lymphocyte or neutrophil function. Establishing a causal relationship between a skin disease and presumed immunodeficient state has been difficult due to the rarity of such conditions, and the limited nature of the techniques used to characterise the immune system response. Severe combined immunodeficiency in dogs is a well characterised primary immunodeficiency state involving lymphocytes; retrovirus infection in cats may lead to an acquired immunodeficient state with some association with certain dermatological conditions although it remains unclear that infection is causally linked with disease. Immunomodulation usually implies stimulating the immune system along a beneficial pathway. Such a therapeutic approach may involve a wide variety of agents, for example intravenous immunoglobulin. There are few randomised controlled trials with veterinary patients that unequivocally demonstrate beneficial responses to immunomodulatory agents. Interferons are cytokines of major interest in human and veterinary medicine for their antiviral, anti-tumour and immunomodulatory effects. The advent of veterinary-licensed products containing recombinant interferon may enable demonstration of the efficacy of interferons for conditions such as canine papillomatosis and feline eosinophilic granuloma complex. Canine pyoderma has been treated with a number of presumed immunomodulatory agents with limited success. With more detailed knowledge of the pathogenesis of pyoderma it may be possible to develop efficacious immunomodulators.

  11. The Role of Spatial Dispersion of Repolarization in Inherited and Acquired Sudden Cardiac Death Syndromes

    2007-01-01

    This review examines the role of spatial electrical heterogeneity within ventricular myocardium on the function of the heart in health and disease. The cellular basis for transmural dispersion of repolarization (TDR) is reviewed and the hypothesis that amplification of spatial dispersion of repolarization underlies the development of life-threatening ventricular arrhythmias associated with inherited ion channelopathies is evaluated. The role of TDR in the long QT, short QT and Brugada syndromes as well as catecholaminergic polymorphic ventricular tachycardia (CPVT) are critically examined. In the long QT Syndrome, amplification of TDR is often secondary to preferential prolongation of the action potential duration (APD) of M cells, whereas in the Brugada Syndrome, it is thought to be due to selective abbreviation of the APD of right ventricular (RV) epicardium. Preferential abbreviation of APD of either endocardium or epicardium appears to be responsible for amplification of TDR in the short QT syndrome. In catecholaminergic polymorphic VT, reversal of the direction of activation of the ventricular wall is responsible for the increase in TDR. In conclusion, the long QT, short QT, Brugada and catecholaminergic polymorphic VT syndromes are pathologies with very different phenotypes and etiologies, but which share a common final pathway in causing sudden cardiac death.

    Monogenic primary immunodeficiency syndromes can affect one or more endocrine organs by autoimmunity during childhood. Clinical manifestations include type 1 diabetes mellitus, hypothyroidism, adrenal insufficiency, and vitiligo. Lipopolysaccharide (LPS)-responsive beige-like anchor protein (LRBA) deficiency was described in 2012 as a novel primary immunodeficiency, predominantly causing immune dysregulation and early onset enteropathy. We describe the heterogeneous clinical course of LRBA deficiency in two siblings, mimicking an autoimmune polyendocrine disorder in one of them in presence of the same underlying genetic mutation. The third child of consanguineous Egyptian parents (Patient 1) presented at 6 months of age with intractable enteropathy and failure to thrive. Later on, he developed symptoms of adrenal insufficiency, autoimmune hemolytic anemia, thrombocytopenia, and infectious complications due to immunosuppressive treatment. The severe enteropathy was non-responsive to the standard treatment and led to death at the age of 22 years. His younger sister (Patient 2) presented at the age of 12 to the endocrinology department with decompensated hypothyroidism, perioral vitiligo, delayed pubertal development, and growth failure without enteropathy and immunodeficiency. Using whole exome sequencing, we identified a homozygous frameshift mutation (c.6862delT, p.Y2288MfsX29) in the LRBA gene in both siblings. To our knowledge, our patient (Patient 2) is the first case of LRBA deficiency described with predominant endocrine phenotype without immunodeficiency and enteropathy. LRBA deficiency should be considered as underlying disease in pediatric patients presenting with autoimmune endocrine symptoms. The same genetic mutation can manifest with a broad phenotypic spectrum without genotype–phenotype correlation. The awareness for disease symptoms among non-immunologists might be a key to early diagnosis. Further functional studies in LRBA deficiency are

    1991-01-01

    Virus-induced acquired immune suppression in mice infected with lymphocytic choriomeningitis virus is shown here to be caused by the CD8+-T-cell-dependent elimination of macrophages/antigen-presenting cells. Surprisingly, this is associated with severe destruction of the follicular organization of lymphoid organs, indicating a crucial role for dendritic cells and marginal zone macrophages in maintaining follicular structure. Once established, this immunopathology cannot be readily reversed by the elimination of CD8+ effector cells. Such a T-cell-mediated pathogenesis may play a pivotal role in acquired virus-induced immunosuppression and may represent one strategy by which virus escapes immune surveillance and establishes persistent infections in initially immunocompetent hosts.

    X-linked severe combined immunodeficiency (XSCID) is caused by mutations of the common gamma chain (gammac) and usually characterized by the absence of T and natural killer (NK) cells. Here, we report an atypical case of XSCID presenting with autologous T and NK cells and Omenn syndrome-like manifestations. The patient carried a splice-site mutation (IVS1+5G>A) that caused most of the mRNA to be incorrectly spliced but produced normally spliced transcript in lesser amount, leading to residual gammac expression and development of T and NK cells. The skin biopsy specimen showed massive infiltration of revertant T cells. Those T cells were found to have a second-site mutation and result in complete restoration of correct splicing. These findings suggest that the clinical spectrum of XSCID is quite broad and includes atypical cases mimicking Omenn syndrome, and highlight the importance of revertant mosaicism as a possible cause for variable phenotypic expression.

    2012-01-01

    Feline immunodeficiency virus (FIV) is a member of the retroviridae family of viruses and causes an acquired immunodeficiency syndrome (AIDS) in domestic and non-domestic cats worldwide. Genome organization of FIV and clinical characteristics of the disease caused by the virus are similar to those of human immunodeficiency virus (HIV). Both viruses infect T lymphocytes, monocytes and macrophages, and their replication cycle in infected cells is analogous. Due to marked similarity in genomic organization, virus structure, virus replication and disease pathogenesis of FIV and HIV, infection of cats with FIV is a useful tool to study and develop novel drugs and vaccines for HIV. Anti-retroviral drugs studied extensively in HIV infection have targeted different steps of the virus replication cycle: (1) inhibition of virus entry into susceptible cells at the level of attachment to host cell surface receptors and co-receptors; (2) inhibition of fusion of the virus membrane with the cell membrane; (3) blockade of reverse transcription of viral genomic RNA; (4) interruption of nuclear translocation and viral DNA integration into host genomes; (5) prevention of viral transcript processing and nuclear export; and (6) inhibition of virion assembly and maturation. Despite much success of anti-retroviral therapy slowing disease progression in people, similar therapy has not been thoroughly investigated in cats. In this article we review current pharmacological approaches and novel targets for anti-lentiviral therapy, and critically assess potentially suitable applications against FIV infection in cats.

    The references provided include data from evidence A and B studies based on the relevant populations. Because many primary immunodeficiencies associated with autoimmune diseases are rare, illustrative cases (evidence D) also are referenced. On the basis of level A evidence, immunoglobulin A deficiency is the most common primary immunodeficiency and is associated with defective mucosal immunity and autoimmune disease. On the basis of strong evidence (level A), Wiskott Aldrich syndrome presents early in life and is associated with autoimmune arthritis and anemia. On the basis of strong evidence in the literature, a number of primary immunodeficiencies are associated with defects in T regulatory cell number and development, cytokine aberrancies, and, as a consequence, production of autoantibodies. On the basis of strong evidence (level A) and case reports (level D), complement deficiency can be associated with autoimmune disease, most notably systemic lupus erythematosus.

In this article, we describe the case of a 42-year-old woman suffering from an aggressive relapsing-remitting multiple sclerosis in which a systematic neuropsychological assessment revealed Gertsmann's syndrome amongst other cognitive disturbances. Brain MRI showed a high concentration of plaques within a left subcortical parietal region that has recently been considered as a crucial node for GS appearance. However, history, taking provided information suggesting that an important part of the GS, may have been present since childhood, evoking a possible neurodevelopmental origin in this patient.

We hypothesize that a ventricular fibrillation occurred after a torsade de pointes, due to drug-induced long QT syndrome during general anesthesia, with probably drug interaction.

    The association in young females of long-standing primary hypothyroidism, isosexual precocious pseudopuberty and multicystic enlarged ovaries was first described in 1960 by Van Wyk and Grumbach. Since then, sporadic case reports have contributed to clarifying the key features of this syndrome. The unique elements that lead to this diagnosis are FSH-dominated sexual precocity combined with a delayed bone age in the presence of hypothyroidism. It is important to recognise this syndrome because initiating simple thyroid hormone replacement completely resolves symptoms and hormone abnormalities, avoiding unnecessary investigations for malignancies or surgical intervention. We describe an 8-year-old girl with autoimmune thyroiditis and severe long-standing hypothyroidism presenting with the clinical features of Van Wyk-Grumbach syndrome, a secondary TSH-secreting adenoma and hyperprolactinaemia. In addition, this girl presented with microcytic anaemia, elevated erythrocyte sedimentation rate (ESR) and two unusual features - a newly developed streaky hyperpigmented skin lesion and parathyroid hormone suppression despite vitamin D deficiency. Thyroxine replacement normalised all hormone abnormalities and shrunk the pituitary adenoma within 9 months, but the new skin lesion persisted. We review the literature and explore the pathophysiology of known and new features that give rise to speculation indicating stimulation of the FSH G protein-coupled receptor by excessive TSH, but LH suppression by hyperprolactinaemia.

    Acquired immunodeficiency syndrome is associated with considerable morbidity in infants and children. It is caused by human immunodeficiency virus (HIV) which can be transmitted vertically from mother to infant early in pregnancy. Transmission might also occur via breast milk. Although the exact transmission rate of HIV from mother to infant is not known, HIV can become a major threat to child survival. This threat is already present in Africa where high seroprevalences have been reported among infants and young children. Transmission via blood products is decreasing due to reliable methods of screening donors for HIV antibody. Where these tests are not available, parenteral transmission will increase the incidence of HIV infection. The clinical picture of HIV infection in children presents with failure to thrive, pulmonary interstitial pneumonitis, hepatosplenomegaly and recurrent bacterial infections. These are common manifestations of diseases prevalent in children in Africa where malnutrition and recurrent parasitic infections already cause immunosuppression. Recognition of the syndrome is therefore difficult. There is no available cure for HIV infection. Supportive treatment and relief of pain and suffering are the only means of management at present. Prevention of spread of the illness to infants and young children is therefore of paramount importance.

    SUMMARY Recently clinical studies have proved without doubts that in patients affect by neurological diseases, like stroke, parkinsonism syndromes and others neurodegenerative pathologies, there is a very elevated incidence of swallowing disorders even severe. The disease can show up in a full blown way, with clinical evident signs like suffocation or frequent and sudden cough, at the moment in which the patient tries to feed or to drink; or it can appear in a less clear way, through an unable protection of the low airway and with possible pathologies ab ingestis. The first signals are represented by frequent resulting of cough reflex at nutrition or hydratation. Important is to assess the validity of this reflection, monitoring the amount of food reflux in the mouth after swallowing, which then could be perceived like foreign body and be aspired. The main diagnostic tests are the pHmetry in 24h, ultrasound, esophagography, videofluoroscopy, endoscopic examination and scintigraphy. Through the FEES (Fiberoptic Endoscopic Evaluation of Swallowing) we can then identify the time of swallowing deficit. Early diagnosis of Dysphagia Syndrome is important to improve living condition and survival of patients. PMID:23285383

    Acquired von Willebrand syndrome (AVWS) is a rare bleeding disorder associated with hematoproliferative disorders, autoimmune conditions, neoplasia and cardiovascular disorders that often present a diagnostic challenge. Monoclonal gammopathy of undetermined significance (MGUS) is one of the most common causes of AVWS that typically presents later in life with mucocutaneous or postsurgical bleeding and multimers consistent with type I or II von Willebrand disease (VWD). Here, we present the case of a patient with a 32-year history of type III VWD that was ultimately found to be AVWS related to an IgG MGUS. In this case report, we highlight the diagnostic challenges of AVWS to ensure proper identification and potentially lifesaving treatment of this rare disorder.

High circulating levels of anti-VW factor immunoglobulin M were documented immunoenzimatically. Heart ultrasound showed abnormalities of the mitral and aortic valves with severe flow alterations. When intravenous immunoglobulins were added to therapy, prompt clinical and laboratory responses occurred: complete cessation of bleeding, raise in hemoglobin, VW factor antigen, VW ristocetin cofactor and factor VIII levels as well as progressive reduction of the anti-VWF autoantibody levels.

    We herein report a case of toxic shock syndrome (TSS) associated with the 2009 pandemic H1N1 (pH1N1) influenza virus and a community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infection in a 16-year-old Vietnamese girl. Staphylococcal enterotoxin B (SEB) was detected in the patient's serum, and the level of anti-SEB antibodies was found to be elevated. A flow cytometric analysis showed evidence of activated SEB-reactive Vβ3+ and Vβ12+ T cells. These data suggest that the CA-MRSA-induced activation of SEB-reactive T cells may cause TSS in patients with pH1N1 virus infection. Moreover, this is the first report describing immunological confirmation of SEB contributing directly to TSS in a patient fulfilling the diagnostic criteria of TSS.

    Twenty different target sites within human immunodeficiency virus (HIV) RNA were selected for studies of inhibition of HIV replication by antisense oligonucleotides. Target sites were selected based on their potential capacity to block recognition functions during viral replication. Antisense oligomers complementary to sites within or near the sequence repeated at the ends of retrovirus RNA (R region) and to certain splice sites were most effective. The effect of antisense oligomer length on inhibiting virus replication was also investigated, and preliminary toxicity studies in mice show that these compounds are toxic only at high levels. The results indicate potential usefulness for these oligomers in the treatment of patients with acquired immunodeficiency syndrome (AIDS) and AIDS-related complex either alone or in combination with other drugs.

Respiratory complications/diseases were: overall pneumonia (n: 14), recurrent pneumonia (n: 10), citomegalovirus associated pneumonia (n: 4), Pneumocystis jiroveci associated pneumonia (n: 1) pulmonary tuberculosis (n: 1), lymphoid interstitial pneumonia (n: 3) and chronic pulmonary disease (n: 7). Microorganisms isolated were mostly atypical and frequently associated with severe and chronic pulmonary damage. A high degree of suspicion is required to detect atypical microorganisms promptly, in order to rapidly implement pathogen targeted therapy that could potentially decrease the possibility of sequelae.

    The acquired immunodeficiency syndrome is a fatal disorder of cell-mediated immunity caused by the human immunodeficiency virus (HIV). As many as one million Americans infected with HIV can expect improved survival with more advanced treatment approaches. Complications of HIV infection occur in the brain, spinal cord, muscle, nerve, joints and other organ systems, which lead to extensive impairments. As survival increases, rehabilitation professionals can anticipate a greater number of referrals for the assessment and management of physical disability in persons with HIV infection. This article reviews HIV-related disease, impairment, disability and handicap pertinent to rehabilitation medicine. An agenda for future research is also proposed. Current knowledge and models or rehabilitation care can be applied to HIV-related physical disability in an effort to improve overall quality of life.

    Ten bronchoscopes that had been used on patients with the acquired immunodeficiency syndrome were sampled to determine the nature and extent of microbial contamination. Samples were taken by irrigating the suction biopsy channel with modified viral transport medium and by swabbing the insertion tube. Sampling was repeated after they had been cleaned in detergent and after two minutes' disinfection in 2% alkaline glutaraldehyde. Before being cleaned the seven bronchoscopes tested by polymerase chain reaction were contaminated with the human immunodeficiency virus, though infectivity and antigen assays gave negative results. Other organisms identified were hepatitis B virus (1), commensal bacteria (9), and Pneumocystis carinii (4). Mean bacterial contamination was 2.27 log colony forming organisms per millilitre. Cleaning the bronchoscope before disinfection removed all detectable contaminants with a reduction in bacterial growth of up to 8 log colony forming units/ml. PMID:1858078

    Twenty different target sites within human immunodeficiency virus (HIV) RNA were selected for studies of inhibition of HIV replication by antisense oligonucleotides. Target sites were selected based on their potential capacity to block recognition functions during viral replication. Antisense oligomers complementary to sites within or near the sequence repeated at the ends of retrovirus RNA (R region) and to certain splice sites were most effective. The effect of antisense oligomer length on inhibiting virus replication was also investigated, and preliminary toxicity studies in mice show that these compounds are toxic only at high levels. The results indicate potential usefulness for these oligomers in the treatment of patients with acquired immunodeficiency syndrome (AIDS) and AIDS-related complex either alone or in combination with other drugs.

    Until recently, the abuse of intravenous drugs was perceived as a problem of the United States, and the acquired immunodeficiency syndrome (AIDS) epidemic was seen mainly as a sexually transmitted disease that tended to affect homosexuals from industrialized nations. However, these perceptions are no longer valid. At present, the abuse of intravenous drugs constitutes the second most common cause of AIDS in the United States and in Europe. This trend has led to a review of the current strategies in the fight against infection with the human immunodeficiency virus (HIV). We analyzed the current epidemiologic trends regarding infection with HIV; we examined the behavioral manifestations of intravenous drug users, particularly from a sexual point of view; and finally, we reviewed the most relevant governmental public policy positions related to drug abuse, specially that focusing on "damage control."

    We studied the immunologic function of 19 sexually active homosexual men, ten of whom had persistent lymphadenopathy. Analysis of mononuclear cell populations distinguished homosexuals from heterosexual controls since, as a group, homosexuals had increased percentages of natural killer cells (Leu 7+), decreased helper-inducer T lymphocytes (OKT-4+), increased suppressor/cytotoxic (OKT-8+) T lymphocytes, low OKT-4:OKT-8 ratios, and depressed mitogenic responses. Homosexuals without lymphadenopathy were distinguishable from controls by increased percentages of Ia+ cells, decreased OKT-4+ cells, and decreased OKT-4:OKT-8 ratios. Four had positive findings simultaneously for hepatitis B surface antigen (HBsAg) and surface antibody, and five had positive findings for HBsAg alone. Homosexuals with lymphadenopathy were distinguishable from controls by increased percentages of Leu 7+ cells, increased total lymphocyte numbers per cubic millimeter, decreased percentages of both OKT-4+ and OKT-8+ cells, abnormal OKT-4:OKT-8 ratios, and depressed mitogenic responses. Only histories of larger numbers of sexually acquired diseases, higher numbers of OKT-8+ cells per cubic millimeter, and lower mitogenic responses in homosexuals with lymphadenopathy distinguished this group from homosexuals without lymphadenopathy. Furthermore, none of the nine patients tested in this group was HBsAg positive. We conclude that homosexuals without lymphadenopathy are distinguishable from those with lymphadenopathy by both immunologic and serologic abnormalities.

    We report 11 patients with multifocal acquired demyelinating sensory and motor (MADSAM) neuropathy, defined clinically by a multifocal pattern of motor and sensory loss, with nerve conduction studies showing conduction block and other features of demyelination. The clinical, laboratory, and histological features of these patients were contrasted with those of 16 patients with multifocal motor neuropathy (MMN). Eighty-two percent of MADSAM neuropathy patients had elevated protein concentrations in the cerebrospinal fluid, compared with 9% of the MMN patients (P < 0.001). No MADSAM neuropathy patient had elevated anti-GM1 antibody titers, compared with 56% of MMN patients (P < 0.01). In contrast to the subtle abnormalities described for MMN, MADSAM neuropathy patients had prominent demyelination on sensory nerve biopsies. Response to intravenous immunoglobulin treatment was similar in both groups (P = 1.0). Multifocal motor neuropathy patients typically do not respond to prednisone, but 3 of 6 MADSAM neuropathy patients improved with prednisone. MADSAM neuropathy more closely resembles chronic inflammatory demyelinating polyneuropathy and probably represents an asymmetrical variant. Given their different clinical patterns and responses to treatment, it is important to distinguish between MADSAM neuropathy and MMN.

  18. Illustrated operative management of spontaneous bleeding and compartment syndrome of the lower extremity in a patient with acquired hemophilia A: a case report

    2014-01-01

    Introduction Spontaneous bleeding resulting in compartment syndrome at the lower adult leg due to acquired hemophilia A is rare. There are no reports on operative management of this entity. Case presentation We present a case of atraumatic compartment syndrome of the lower leg due to acquired factor VIII deficiency, in an 83-year-old Caucasian man of European descent. He was treated surgically with a long and complicated postoperative course after presenting to a community hospital with a 2-day history of increasing pain and swelling in his left lower leg without a previous history of trauma. Conclusions Awareness, prompt diagnosis and effective treatment of compartment syndrome caused by a rare bleeding disorder, which is usually acquired by the elderly, is essential and may spare a patient from surgery or even limb loss, if early administration of recombinant factor VIIa is effective. The course of disease in a patient with operative management of spontaneous bleeding, compartment syndrome and acquired hemophilia A may be prolonged. However, an interdisciplinary approach with meticulous surgical treatment and bleeding management with recombinant factor VIIa as well as inhibitor eradication by immunosuppressive treatment can be successful and expensive.

    Hematological complications occur frequently in patients with both primary and secondary immunodeficiency disorders. Anemia, thrombocytopenia or leukopenias may bring these individuals to the attention of hematologists. Conversely, evidence suggesting a lymphoproliferative disorder may be the cause for referral. This session will provide an update on the diagnosis and treatment of immunodeficiency diseases ranging from isolated defects in antibody production to the severe combined immunodeficiencies (SCID). Immunodeficiency diseases have traditionally been defined as defects in the development and function of T and B cells, the primary effector cells of specific cellular and humoral immunity. However, it has become increasingly evident that innate immune mechanisms contribute greatly to host defense, either through acting alone or by enhancing specific T and B cell responses. In Section I, Dr. Lewis Lanier reviews the burgeoning information on the extensive families of activating and inhibitory immunoreceptors that are expressed on NK cells, dendritic cells, T and B cells, and phagocytic cells. He provides an overview on the biological functions of these receptors in host defense. In Section II, Dr. Mary Ellen Conley defines the spectrum of antibody deficiency disorders, the most frequently occurring types of primary immunodeficiencies. She covers the different defects in B-cell development and function that lead to antibody deficiencies, and includes diagnosis and therapy of these disorders. In Section III, Dr. Jennifer Puck discusses the diagnosis and treatment of the different types of SCID. She describes the genetic basis for SCID, and the benefits, pitfalls, and complications of gene therapy and bone marrow transplantation in SCID patients.

    We investigated a case of acquired von Willebrand syndrome (AVWS) secondary to a nonneutralizing anti-von Willebrand factor (VWF) antibody associated with an autoimmune disorder. At diagnosis, VWF activity (VWF:Act), antigen (VWF:Ag), multimers, and factor VIII coagulant activity were virtually absent. VWF propeptide (VWFpp) was elevated with an infinitely high VWFpp to VWF:Ag ratio (VWFpp:Ag) consistent with rapid VWF clearance. Immunosuppressive treatment resulted in phenotypic remission 1 with normalization of VWF/factor VIII levels and multimer pattern. However, VWFpp:Ag remained elevated (∼2× normal), consistent with ongoing VWF clearance by the remaining anti-VWF antibody still present by enzyme-linked immunosorbent assay. This suggests that increased VWF secretion was compensating for the incomplete remission state. Relapse occurred when VWFpp:Ag was again infinitely high, with associated decreased VWFpp but unchanged anti-VWF titers; switching the balance to favor VWF clearance over secretion. Complete remission with undetectable anti-VWF occurred only when VWFpp:Ag was normal. This case of relapsing-remitting AVWS demonstrates the use of VWFpp:Ag for predicting remission status.

    The acquired demyelinating neuropathies can be divided into those with an acute onset and course and those with a more chronic course. The acute neuropathies present as Guillain-Barré syndrome and include acute inflammatory demyelinating polyradiculoneuropathy (AIDP), Miller Fisher syndrome, acute motor axonal neuropathy (AMAN), acute motor and sensory axonal neuropathy (AMSAN), and acute pandysautonomia. The chronic neuropathies are collectively known as chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and include MADSAM (multifocal acquired demyelinating sensory and motor neuropathy, also know as Lewis-Sumner syndrome) and DADS (distal acquired demyelinating symmetric neuropathy) as variants. The clinical features, pathology, pathogenesis, diagnosis, treatment, rehabilitation, and prognosis of these neuropathies are discussed.

    Hepatitis C virus (HCV) has become a major contributor to morbidity and mortality in patients with human immunodeficiency virus (HIV). It is estimated that 30% to 50% of patients with HIV are coinfected with HCV. Advances in antiretroviral therapy and improved life expectancy of HIV patients have resulted in an emergence of HCV-induced liver disease as a leading cause of significant morbidity and death in this population. Clinically, hepatitis C is a more severe disease in HIV-infected individuals, characterized by rapid progression toward end-stage liver disease. Highly active antiretroviral therapy is the mainstay of current acquired immunodeficiency syndrome management. One of the limiting side effects of combination therapy for HIV is hepatotoxicity, which is more common and often more serious in patients with underlying liver disease. Management of coinfected patients has no strict guidelines, but it is generally accepted that HIV infection needs to be treated before HCV. Hepatitis C in coinfected individuals is probably best treated using combination therapy (interferon alpha and ribavirin). It appears that combination therapy can safely be administered to this population and that previous concerns about ribavirin/zidovudine antagonism are unsubstantiated in clinical practice. Although initial results using only interferon alpha showed poor results in HIV coinfected patients, combination therapy seems to be as effective as in the general population. All HIV-HCV coinfected patients should be vaccinated against hepatitis B and hepatitis A; vaccines are safe and effective.

    LP-BM5 retrovirus complex-infected C57BL/6 mice develop immunodeficiency, somewhat analogous to AIDS, termed murine AIDS (MAIDS). After secondary stimulation with syngeneic B-cell lymphomas from LP-BM5-infected mice, C57BL/6 mice produced vigorous CD8+ cytotoxic T lymphocytes specific for MAIDS-associated tumors. An anti-LP-BM5 specificity was suggested because spleen and lymph node cells from LP-BM5-infected mice served as target cells in competition assays, and cells from LP-BM5, but not ecotropic, virus-infected mice functioned as secondary in vitro stimulators to generate cytotoxic T lymphocytes to MAIDS tumors.

    Virologic and immunologic studies were performed on five patients presenting with primary human immunodeficiency virus type 1 (HIV-1) infection. CD8+ cytotoxic T lymphocyte (CTL) precursors specific for cells expressing antigens of HIV-1 Gag, Pol, and Env were detected at or within 3 weeks of presentation in four of the five patients and were detected in all five patients by 3 to 6 months after presentation. The one patient with an absent initial CTL response had prolonged symptoms, persistent viremia, and low CD4+ T-cell count. Neutralizing antibody activity was absent at the time of presentation in all five patients. These findings suggest that cellular immunity is involved in the initial control of virus replication in primary HIV-1 infection and indicate a role for CTL in protective immunity to HIV-1 in vivo.

    The primary etiologic agent of the acquired immune deficiency syndrome (AIDS) is a human T-lymphotropic retrovirus (the AIDS virus). However, the pathogenesis of this virus suggests that other cofactors may contribute to the development of clinically overt disease. The hepatitis B virus (HBV) has been implicated as a potential cofactor because HBV and AIDS virus infections frequently coexist, striking similarities exist in their epidemiologic patterns, and recent data indicate that HBV is lymphotropic. To establish the prevalence of HBV infections in lymphoid cells from individuals with AIDS-related disorders, sera and peripheral blood mononuclear cells (PBMC) from 16 males with AIDS virus infections were examined for the presence of HBV DNA by DNA X DNA blot hybridization. Fifteen (94%) of these individuals had serologic evidence of a recent or prior HBV infection. HBV DNA was detected in the PBMC of all of these patients, regardless of existing HBV serology. Among the 36 control individuals without AIDS-related symptomatology, PBMC-associated HBV DNA was detected in 8 of 14 carriers of hepatitis B surface antigen (HBsAg) and in 3 of 10 individuals immune to HBV, but it was absent from the PBMC of 12 individuals without HBV infection. In all instances, the HBV DNA was extrachromosomal and existed as replicative intermediates or high molecular weight oligomers of the viral genome. Replicative intermediates and serum-associated HBV DNA were detected in all hepatitis B e antigen-positive carriers, regardless of their clinical status. In contrast, the high molecular weight oligomers of HBV DNA were detected in the PBMC of all of the AIDS virus-infected patients examined, but in only 33% of those in the control group who had evidence of HBV infection. This finding suggests that a unique and complex HBV-host-cell interaction exists in patients infected with the AIDS virus.

    Simian immunodeficiency virus (SIV) is a T-lymphotropic lentivirus that is genetically, immunologically, and morphologically related to the human immunodeficiency viruses type 1 and 2 (HIV-1, HIV-2). In rhesus monkeys, SIV induces a progressively fatal immunodeficiency syndrome strikingly similar to human acquired immunodeficiency syndrome (AIDS). The tissue and cellular tropism of SIV was determined by immunocytochemistry and in situ hybridization using a 3.48 kilobase SIV envelope gene probe labeled with biotin, {sup 35}S, or {sup 3}H. Probes labeled with {sup 35}S nonspecifically bound to tissue eosinophils and produced poor signal resolution compared to tritium labeled probes. Biotin labeled probes did not detect SIV under similar hybridization conditions. Formalin-fixed, paraffin-embedded tissues produced strong hybridization signal with superior morphology compared to frozen tissues. Gastrointestinal, respiratory, and lymphoid tissues most frequently contained SIV RNA. The distribution of SIV did not correlate with sex, or viral inoculum, but was most extensive in animals with SIV induced granulomatous encephalitis. SIV was most frequently observed in lymphocytes and macrophages. In the brain focal granulomas were composed almost entirely of EBM11+, lysozyme+, macrophages which contained large amounts of SIV RNA and p27 core protein detected by the monoclonal antibody R1C7. Cells away from granulomas in the brain parenchyma and around blood vessels contained virus and were compatible with oligodendrocytes and astrocytes. Lymph nodes in follicular hyperplasia contained small numbers of SIV positive cells compatible with lymphocytes in the paracortex and mantle zones as well as in cells of the germinal center. Lymph nodes in various stages of follicular depletion with expanded paracortices contained large numbers of cells with SIV RNA in lymphocytes and macrophages.

    In the modern antiretroviral therapy (ART) era, motivated people living with human immunodeficiency virus (HIV) who have access to therapy are expected to maintain viral suppression indefinitely and to receive treatment for decades. Hence, the current clinical scenario has dramatically shifted since the early 1980s, from treatment and prevention of opportunistic infections and palliative care to a new scenario in which most HIV specialists focus on HIV primary care, ie, the follow up of stable patients, surveillance of long-term toxicities, and screening and prevention of age-related conditions. The median age of HIV-infected adults on ART is progressively increasing. By 2030, 3 of every 4 patients are expected to be aged 50 years or older in many countries, more than 80% will have at least 1 age-related disease, and approximately one third will have at least 3 age-related diseases. Contemporary care of HIV-infected patients is evolving, and questions about how we might monitor and perhaps even treat HIV-infected adults have emerged. Through key published works, this review briefly describes the most prevalent comorbidities and age-associated conditions and highlights the differential features in the HIV-infected population. We also discuss the most critical aspects to be considered in the care of patients with HIV for the management and prevention of age-associated disease. PMID:27419169

    2016-12-01

    Community-acquired pneumonia (CAP) is associated with significant morbidity and mortality in Latin America and the Caribbean (LAC) region. Poverty, socioeconomic factors, and malnutrition influence the incidence and outcome of CAP in LAC. In LAC, Streptococcus pneumoniae is the most frequent microorganism responsible for CAP, (incidence: 24-78%); the incidence of atypical microorganisms is similar to other regions of the world. Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) is a growing problem in the LAC region, with the Caribbean being the second most affected area worldwide after Sub-Saharan Africa. Pneumococcal pneumonia remains the most common cause of CAP in HIV-infected patients, but Pneumocystis jirovecii and tuberculosis (TB) are also common in this population. The heterogeneity of the health care systems and social inequity between different countries in LAC, and even between different settings inside the same country, is a difficult issue. TB, including multidrug-resistant TB, is several times more common in South American and Central American countries compared with North America. Furthermore, hantaviruses circulating in the Americas (new world hantaviruses) generate a severe respiratory disease called hantavirus pulmonary syndrome, with an associated mortality as high as 50%. More than 30 hantaviruses have been reported in the Western Hemisphere, with more frequent cases registered in the southern cone (Argentina, Chile, Uruguay, Paraguay, Bolivia, and Brazil). Respiratory viruses (particularly influenza) remain an important cause of morbidity and mortality, particularly in the elderly. Low rates of vaccination (against influenza as well as pneumococcus) may heighten the risk of these infections in low- and middle-income countries.

    SCID can be caused by various genetic mutations leading to distinctive phenotypes according to the presence of T, B and NK cells. Artemis is a gene encoded on chromosome 10p. The deficiency of this molecule causes an inability to repair DNA double strand breaks and is one of the causes of radiosensitive T-B-NK+ SCID. The syndrome usually presents with opportunistic infections in the first years of life that leads to death if not treated with stem cell transplantation. The spectrum of the disease can be wide because of the heterogeneity of the mutations. Herein we present an atypical SCID (CID) patient with Artemis defect mimicking hyper IgM syndrome. Our patient had high serum IgM with low IgG and IgA levels, lymphocytosis and recurrent infections, intractable diarrhea, growth retardation, systemic CMV infection and sclerosing cholangitis. He also developed large granular lymphocytic leukemia and survived until the age of 6.5 years.

With advancing age, moderate global developmental delay, susceptibility to frequent viral illnesses, otitis media, and purulent conjunctivitis were identified. Because of the repeated infections, an immunological evaluation was pursued and identified impaired antibody memory responses following pneumococcal vaccine administration. Immunoglobulin replacement therapy and nutritional support were employed as mainstays of therapy. The child is now aged 12 years and still without diarrhea. Whole exome sequencing identified compound heterozygous mutations in the TTC37 gene, a known cause of the trichohepatoenteric syndrome (THES). This case extends the known phenotype of THES and defines a potential subset for inclusion as an immune overlap syndrome.

    A non-human primate model for acquired immunodeficiency syndrome (AIDS), the simian immunodeficiency virus (SIV)-infected rhesus monkey, was used to explore the role of the AIDS virus-specific cytotoxic T-lymphocyte (CTL) response in disease pathogenesis. This CTL response was measured using the major histocompatibility complex (MHC) class I/peptide tetramer technology. Large numbers of tetramer-binding CD8+ T lymphocytes were demonstrable not only in the peripheral blood, but in lymph nodes and even in semen of chronically SIV-infected monkeys. The central role of these effector T lymphocytes in containing SIV spread during primary infection was demonstrated by showing that early SIV clearance during primary infection correlated with the emergence of the tetramer binding CD8+ T lymphocytes and that in vivo depletion of CD8+ lymphocytes eliminated the ability of the infected monkeys to contain SIV replication. These observations suggest that an effective AIDS vaccine should elicit a potent virus-specific CTL response. In fact, a live, recombinant SIV vaccine constructed using the attenuated pox virus vector modified vaccinia Ankara (MVA) elicited a high-frequency CTL response, comparable in magnitude to that elicited by SIV infection itself. This suggests that vaccine modalities such as MVA may prove useful in creating an effective human immunodeficiency virus (HIV) vaccine. These studies also indicate the power of both the SIV/macaque model and MHC class I/peptide tetramers for assessing AIDS vaccine strategies.

    The pace of discovery in primary immunodeficiency continues to accelerate. In particular, lymphocyte defects have been the source of the most impressive expansion in recent years. Novel forms of agammaglobulinemia, class-switch defects, and T-B(+) severe combined immunodeficiency have been described. Little by little, the genetic heterogeneity of the common variable immunodeficiency and IgA deficiency phenotypes continues to be unraveled as new molecular defects have been reported in these patients as well. The phenotypic spectrum of DiGeorge syndrome has been further developed, along with promising advances in therapy. Defects of nuclear factor kappaB regulation and Toll-like receptor signaling have been described, along with defects of chemokine receptors and cytoplasmic proteases. Clinically defined immunodeficiencies, such as hyper-IgE syndrome and idiopathic CD4 lymphocytopenia, are also discussed. Finally, significant adverse effects in some patients have tempered initial enthusiasm for gene therapy.

    A prospective study of US Peace Corps volunteers (PCVs) serving in Zaire, central Africa, was undertaken to determine the risk of human immunodeficiency virus (HIV) and hepatitis B virus infection in an acquired immunodeficiency syndrome-aware expatriate population living in an area of high endemicity for both diseases. Of the 338 PCVs who served in Zaire between October 1985 and May 1988, 282 (83%) were enrolled, representing 7776 volunteer-months of service. Analyses of serum samples for HIV and hepatitis B virus were performed on enrollment and at completion of service. All PCVs received extensive education and counseling regarding HIV and acquired immunodeficiency syndrome throughout their stay in Zaire. There were no documented seroconversions to HIV among 282 PCVs who lived in Zaire for periods ranging from 1 to 81 months, with a mean length of stay of 27.4 months. Of the 14 (6.2%) of 226 PCVs tested who had at least one positive serologic marker for infection with hepatitis B virus, none was documented to have seroconverted during service. During the study period, the rate of all sexually transmitted diseases among PCVs in Africa decreased from 131 to 68 per 1000 study population per year, and there were 52 cases of confirmed malaria among volunteers in Zaire. These data suggest that the risk of acquiring infection with HIV or hepatitis B virus in PCVs in Zaire is very low, and there is no evidence for unusual modes of transmission.

    Human immunodeficiency virus type 1 (HIV-1) can be transmitted through blood transfusion. The first transfusion-acquired immunodeficiency syndrome (AIDS) patient in Taiwan was a 46-year-old woman who received two units of whole blood during a hysterectomy at a provincial hospital in 1985. In 1991, she experienced a herpes zoster infection. In March 1993, she had extensive herpetic gingivostomatitis and another herpes zoster attack, and was treated at the same hospital. Two months later, she had oral candidiasis and was treated at a medical center. She was not tested for HIV-1 infection until she developed Pneumocystis carinii pneumonia in June 1993. In February 1994, and developed cytomegalovirus retinitis and died 6 months later. Donor blood given to the patients during the hysterectomy was HIV-1 positive. The donor's HIV infection was discovered in 1991 and he died of AIDS in 1993. As blood centers in Taiwan did not start screening for HIV-1 until January 1988, it is urgently recommended that any individual who received a blood transfusion between 1984 and 1987 in Taiwan and who currently experiences repeated episodes of opportunistic infections have an HIV-1 blood test. The receipt of a blood transfusion between 1984 and 1987 should be listed by the Department of Health as an indication for HIV-1 screening.

    Since the original description of X-linked agammaglobulinemia in 1952, the number of independent primary immunodeficiency diseases (PIDs) has expanded to more than 100 entities. By definition, a PID is a genetically determined disorder resulting in enhanced susceptibility to infectious disease. Despite the heritable nature of these diseases, some PIDs are clinically manifested only after prerequisite environmental exposures but they often have associated malignant, allergic, or autoimmune manifestations. PIDs must be distinguished from secondary or acquired immunodeficiencies, which are far more common. In this review, we will place these immunodeficiencies in the context of both clinical and laboratory presentations as well as highlight the known genetic basis. PMID:17162365

    We describe the first reported case of bacterial pyomyositis of the right thigh caused by Streptococcus anginosus (S. milleri group) in an HIV-infected patient. The clinical presentation was complicated by multiple ring-enhancing lesions detected on magnetic resonance imaging of the brain. Evaluation for central nervous system toxoplasmosis,syphilis, and cryptococcal infection was negative. Aggressive antibiotic therapy directed against S. anginosus and surgical debridement were limb salvaging. Clinicians should considerS. anginosus as a causative pathogen in HIV-associated pyomyositis, particularly in complex presentations. Prompt surgical drainage may minimize complications due to S. anginosus, a pathogen associated with significant sequelae due to its invasive nature.

    In order to assess the efficacy and the toxicity of zidovudine in AIDS patients, we have studied, prospectively, 117 patients that were treated with this drug, in several andalusian hospitals between January 1988 and June 1990. Initial dose of the drug was 200 mg every 4 hours. Mean survival was 100% at 6 months and 66.5% at 23 months. Survival at 19 months was higher in ADVP (77%) than in non-ADVP (48%). A positive influence on weight. Karnofsky index and number of opportunistic infections during the six first months of treatment was recorded, benefit that was lost progressively from that moment onwards. Main adverse effects were hematological, 10.1% of the patients requiring transfusions due to hemoglobin lower than 6.5 gr%. The more frequent cause to stop therapy was severe neutropenia (less than 500 neutrophils per mm). We consider that the beneficial effect of zidovudine is only transient, diminishing gradually when the treatment is prolonged. At present doses adverse effects are moderate not being present in most of the patients.

    Plasma levels of vitamin E (vit E) and polyunsatured fatty acids of phospholipids (PUFA-PL) as well as erythrocyte glutathione peroxidase (GSH-Px) activity are significantly lower (p less than 0.001) in patients HIV sero-positive (AIDS and ARC cases) both affected and not affected with seborrheic dermatitis and in 32% of HIV sero-negative intravenous drug abusers (IVDA, A subgroup) than in controls. The deficiency of PUFA-PL (mainly C20:3 n-6, C20:4 n-6 and C22:6 n-3) which is associated with a significant increase (p less than 0.001) of saturated palmitic and stearic acids and monounsaturated oleic acid, cannot be correlated to an active lipoperoxidative process. In fact the levels of thiobarbituric acid-reactive materials (TBA-RM) are not increased in the plasma of HIV sero-positive patients and A subgroup of IVDA. It is likely that the reduction of PUFA-PL is due to an inhibition of hepatic microsomal desaturase enzymes (delta 6 desaturase, delta 5 desaturase, delta 4 desaturase) which are involved in both n-6 and n-3 pathways. Since IVDA represent, and not only in Italy, a major risk category for HIV infection, we suggest that reduced blood levels of vit E, GSH-Px and particularly PUFA-PL may be added to the list of risk factors favouring the onset and the development of AIDS.

    We describe the case of a homosexual man with asymptomatic infection with human immunodeficiency virus and hepatitis B virus who developed primary hepatic lymphoma. The lymphoma presented with rapid enlargement of the liver, and ultrasound examination revealed multiple hypoechoic lesions within the liver. Histological examination of the liver showed massive replacement by lymphomatous tissue, as well as changes of chronic active hepatitis B. Immunohistochemical stains for hepatitis B surface and core antigens were strongly positive in almost all hepatocytes, but not in tumor tissue. Whereas the occurrence of lymphoma probably is related to HIV infection, possible interactions between hepatitis B virus and HIV infection are discussed. Thus, the presence of mass lesions within the liver in a patient with HIV infection should raise the possibility of hepatic lymphoma even if there is no evidence of generalized lymphadenopathy.

    As at 31 May 1990, fifty Singaporeans with the Human Immunodeficiency Virus (HIV) infection had been detected. Of these, nineteen had the Acquired Immunodeficiency Syndrome (AIDS). The majority of infected persons had been infected through sexual contact (homosexual 52%; bisexual 24%; heterosexual 20%) with men and women from countries where HIV infection was prevalent. The majority of infected patients (88%) were in the age range 20-39 years. There was one case of blood transfusion-associated AIDS. There were no infected paediatric or haemophiliac cases or intravenous drug use in any of the patients. A spectrum of AIDS-related opportunistic infections and cancers was observed, and Pneumocystis carinii pneumonia was the most frequent presentation. Thirteen patients with AIDS had died and the median survival time was about seven months.

    Medical records of 52 human immunodeficiency virus (HIV)-infected patients who underwent a total of 80 anorectal operations from January 1985 to January 1990 were retrospectively reviewed to determined whether anorectal surgical wounds healed in HIV-infected patients and the mean survival time of these patients after surgery. Twenty-four operations were performed in asymptomatic HIV-infected patients, 19 in HIV-infected patients with persistent lymphadenopathy, and 37 in patients with acquired immunodeficiency syndrome. Wounds healed in 49 patients (94%). The mortality rate 30 days after surgery was 2%. There were no major complications. The mean survival time of HIV-infected patients after surgery was 15 months. We conclude that anorectal surgical wounds heal in most HIV-infected patients and that the survival time after surgery of HIV-infected patients with anorectal disease justifies appropriate surgical treatment.

    Nowadays, the human immunodeficiency virus infection (HIV) is a chronic disease. In the frequent clinical situations with fever, lymph nodes and loss weight it is necessary to determine their etiology, for establishing a specific treatment. Gastrointestinal opportunistic infections or gastric lymphomatous or sarcomatous process, which can accumulate Ga67, may be present in the patient with acquired immunodeficiency syndrome. We report 2 cases with gastric uptake in which endoscopy and biopsy was obtained. In the first one, with previous treatment with omeprazol and almalgate for gastroesophagic reflux, endoscopy and biopsy were normal and in the second patient an Helicobacter pylori infection was diagnosed. We think that gastric uptake of Ga67 in HIV patients, must indicate to the clinician to rule out associated pathologies.

    This study is among the first to examine knowledge about human immunodeficiency virus (HIV) and behavioral risks for HIV transmission among veterans with severe mental illness (SMI), a group at high risk for HIV infection. This study examined associations between accuracy of HIV knowledge, risk behaviors, and clinical and demographic characteristics in a sample of male veteran psychiatric inpatients diagnosed with SMI (N = 353). Results showed high rates of inaccurate HIV knowledge, with > 40% of patients demonstrating some inaccuracies, particularly those related to the progression and symptoms of acquired immunodeficiency syndrome. Inaccurate HIV knowledge was associated with older age, minority status, education level, marital status, no homelessness within the previous 6 months, and no reported history of illicit intranasal drug use. There is a need for more effective HIV prevention interventions for persons with SMI.

    Plasmablastic lymphoma is a rare and aggressive subtype of diffuse large B cell non-Hodgkin lymphoma, originally described in the oral cavity of male adults with acquired immune deficiency syndrome. It is composed of neoplastic ceils which resemble immunoblasts but present immunophenotype distinctive of plasma cell and Epstein-Barr virus latent infection. In children, it is an even rarer disease. We present a case of oral plasmablastic lymphoma in a vertically transmitted human immunodeficiency virus-positive five-year-old child.

    Objectives. We determined metabolic syndrome (MetS) prevalence and assessed the agreement between different diagnostic criteria in HIV-infected South Africans. Method. A random sample included 748 HIV-infected adult patients (79% women) across 17 HIV healthcare facilities in the Western Cape Province. MetS was defined using the Joint Interim Statement (JIS 2009), International Diabetes Federation (IDF 2005), and Adult Treatment Panel III (ATPIII 2005) criteria. Results. Median values were 38 years (age), 5 years (diagnosed HIV duration), and 392 cells/mm3 (CD4 count), and 93% of the participants were on antiretroviral therapy (ART). MetS prevalence was 28.2% (95%CI: 25–31.4), 26.5% (23.3–29.6), and 24.1% (21–27.1) by the JIS, IDF, and ATPIII 2005 criteria, respectively. Prevalence was always higher in women than in men (all p < 0.001), in participants with longer duration of diagnosed HIV (all p ≤ 0.003), and in ART users not receiving 1st-line regimens (all p ≤ 0.039). The agreement among the three criteria was very good overall and in most subgroups (all kappa ≥ 0.81). Conclusions. The three most popular diagnostic criteria yielded similarly high MetS prevalence in this relatively young population receiving care for HIV infection. Very good levels of agreement between criteria are unaffected by some HIV-specific features highlighting the likely comparable diagnostic utility of those criteria in routine HIV care settings.

    Henderson, Cailin; Goldbach-Mansky, Raphaela

    2010-01-01

    INTRODUCTION Interleukin -1 was the first cytokine identified and is a powerful inducer of fever and inflammation. The biologically active receptor for IL-1, shares signaling pathways with some pathogen recognition receptors, the toll like receptors (TLRs) which early on suggested an important role in innate immune function. DISCUSSION The discovery that some intracellular “danger receptors”, the NOD like receptors (NLRs) can assemble to form multimolecular platforms, the inflammasomes, that not only sense intracellular danger but also activate IL-1β, has provided the molecular basis for the integration of IL-1 as an early response mediator in danger recognition. The critical role of balancing IL-1 production and signaling in human disease has recently been demonstrated in rare human monogenic diseases with mutations that affect the meticulous control of IL-1 production, release and signaling by leading to decreased or increased TLR/IL-1 signaling. In diseases of decreased TLR/IL-1 signaling (IRAK-4 and MyD88 deficiencies) patients are at risk for infections with gram positive organisms; and in diseases of increased signaling, patients develop systemic autoinflammatory diseases (Cryopyrin associated periodic syndromes (CAPS), and deficiency of the IL-1 receptor antagonist (DIRA)). CONCLUSION Monogenic defects in a number of rare diseases that affect the balance of TLR/IL-1 signaling have provided us with opportunities to study the systemic effects of IL-1 in human diseases. The molecular defects in CAPS and DIRA provided a therapeutic rationale for targeting IL-1 and the impressive clinical results from IL-1 blocking therapies have undoubtedly confirmed the pivotal role of IL-1 in human disease and spurred the exploration of modifying IL-1 signaling in a number of genetically complex common human diseases.

    Purpose of review Neutropenia is a feature of several primary immunodeficiency diseases (PIDDs). Because of the diverse pathophysiologies of the PIDDs and the rarity of each disorder, data are often lacking, leading to the necessity of empiric treatment. Recent developments in the understanding of neutropenia in several of the PIDDs make a review of the data timely. Recent findings The category of severe congenital neutropenia continues to expand. Mutations in G6PC3 have been identified as the cause of neutropenia in a minority of previously molecularly undefined cases. Recent advances have broadened our understanding of the pathophysiology and the clinical expression of this disorder. A possible function of the C16orf57 gene has been hypothesized that may explain the clinical overlap between Clerucuzio-type poikiloderma with neutropenia and other marrow diseases. Plerixafor has been shown to be a potentially useful treatment in the warts, hypogammaglobulinemia, infection, and myelokathexis syndrome. Investigations of patients with adenosine deaminase deficient severe combined immunodeficiency have identified neutropenia, and particularly susceptibility to myelotoxins, as a feature of this disorder. Granulocyte-colony stimulating factor is the treatment of choice for neutropenia in PIDD, whereas hematopoietic cell transplantation is the only curative option. Summary The number of PIDDs associated with neutropenia has increased, as has our understanding of the range of phenotypes. Additional data and hypotheses have been generated helping to explain the diversity of presentations of neutropenia in PIDDs. PMID:23196894

    A Sjögren syndrome was confirmed histologically in a 19 year old woman. Four years later, periarteritis nodosa (PAN) with characteristic vascular lesions on muscle biopsy occurred simultaneously with lymphatic hyperplasia comprising splenomegaly and polyadenopathy. The PAN was cured with corticosteroids and cyclophosphamide and the lymphadenopathy regressed. Several months after treatment was stopped the lymphadenopathy recurred which histologically resembled a malignant non-hodgkin lymphoplasmocytoma secreting an IgM kappa monoclonal immunonoglobulin. During the PAN and the establishment of the lymphoproliferative syndrome a severe C4 deficit was detected which disappeared after chemotherapy.

    Increased risk of developing autoimmune manifestations has been identified in different primary immunodeficiencies (PIDs). In such conditions, autoimmunity and immune deficiency represent intertwined phenomena that reflect inadequate immune function. Autoimmunity in PIDs may be caused by different mechanisms, including defects of tolerance to self-antigens and persistent stimulation as a result of the inability to eradicate antigens. This general immune dysregulation leads to compensatory and exaggerated chronic inflammatory responses that lead to tissue damage and autoimmunity. Each PID may be characterized by distinct, peculiar autoimmune manifestations. Moreover, different pathogenetic mechanisms may underlie autoimmunity in PID. In this review, the main autoimmune manifestations observed in different PID, including humoral immunodeficiencies, combined immunodeficiencies, and syndromes with immunodeficiencies, are summarized. When possible, the pathogenetic mechanism underlying autoimmunity in a specific PID has been explained. PMID:27766253

    Accurate diagnosis of predisposition to long QT syndrome is crucial for reducing the risk of cardiac arrhythmias. In recent years, drug-induced provocative tests have proved useful to unmask some latent mutations linked to cardiac arrhythmias. In this study we expanded this concept by developing a prototype for a computational provocative screening test to reveal genetic predisposition to acquired Long-QT Syndrome (aLTQS). We developed a computational approach to reveal the pharmacological properties of IKr blocking drugs that are most likely to cause aLQTS in the setting of subtle alterations in IKr channel gating that would be expected to result from benign genetic variants. We used the model to predict the most potentially lethal combinations of kinetic anomalies and drug properties. In doing so, we also implicitly predicted ideal inverse therapeutic properties of K channel openers that would be expected to remedy a specific defect. We systematically performed “in silico mutagenesis” by altering discrete kinetic transition rates of the Fink et al. Markov model of human IKr channels, corresponding to activation, inactivation, deactivation and recovery from inactivation of IKr channels. We then screened and identified the properties of IKr blockers that caused acquired Long QT and therefore unmasked mutant phenotypes for mild, moderate and severe variants. Mutant IKr channels were incorporated into the O’Hara et al. human ventricular action potential (AP) model and subjected to simulated application of a wide variety of IKr-drug interactions in order to identify the characteristics that selectively exacerbate the AP duration (APD) differences between wild-type and IKr mutated cells. Our results show that drugs with disparate affinities to conformation states of the IKr channel are key to amplify variants underlying susceptibility to acquired Long QT Syndrome, an effect that is especially pronounced at slow frequencies. Finally, we developed a mathematical

    Acquired Fanconi syndrome (FS) is a rare presentation of monoclonal gammopathy. We retrospectively summarized the cases of eight patients with FS secondary to monoclonal gammopathy at Peking Union Medical College Hospital (PUMCH) from January 2007 to April 2014. All patients had generalized or partial impairment of proximal renal tubular function. Six patients were diagnosed with monoclonal gammopathy of undetermined significance (MGUS), and two were diagnosed with multiple myeloma (MM). Although chemotherapy was administered to the two patients with MM and to one patient with MGUS, decreased paraprotein levels did not lead to improvements in metabolic abnormalities. All patients received continuous supplementation with deficient nutrients, leading to marked remission of bone pain and improved quality of life. Although renal function in most patients gradually declined, none of the patients developed end-stage renal disease (ESRD) during an average follow-up time of 31 months, and no case of MGUS has yet transformed into MM.

    A 52-year-old woman was admitted to the hospital three times in a span of 5 years in hypovolemic shock because of spontaneous and massive bleeding in the pleural and abdominal cavity. Blood tests revealed a high number of blood cells, and bone marrow smears showed trilineage myeloproliferation. Serum erythropoietin level was decreased. Analysis revealed a V617F mutation in the JAK2 protein. Her activated partial thromboplastin time was slightly prolonged, the ratio between von Willebrand factor (vWF) propeptide and vWF antigen was in the normal range, but the ratio between vWF and ristocetin cofactor was decreased dramatically. Further investigation revealed the absence of large and intermediate vWF-multimers. She was diagnosed with polycythemia vera with acquired von Willebrand syndrome. The bleeding was stopped using a transfusion of freshly thawed plasma and cryoprecipitate.

    Compared to healthy homosexual and heterosexual men, homosexual men with acquired immune deficiency syndrome (AIDS) possessed significantly higher levels of IgG antibody to the neutral glycolipid asialo GM1 (ganglio-N-tetraosylceramide) (P less than 0.01). Of 31 homosexuals with AIDS, 36% possessed levels of this antibody that were at least two standard deviations above the mean of the healthy men. Furthermore, asialo GM1 antibody could be removed from serum by adsorption with spermatozoa. Weekly rectal insemination of male rabbits with rabbit semen also led to the appearance of antibody to asialo GM1 by 15 weeks. These results suggest that asialo GM1 is a component of ejaculated spermatozoa and demonstrate that rectal insemination by itself can lead to the production of antibodies to this glycolipid in the rabbit. In addition, asialo GM1 antibodies may be of value as a serological marker for the early detection of individuals with AIDS. PMID:6652964

    Recent data suggest that aminosugar derivatives which inhibit glycoprotein processing have potential anti-human immunodeficiency virus (HIV) activity. These inhibitory effects may be due to disruption of cell fusion and subsequent cell-cell transmission of the acquired immunodeficiency syndrome (AIDS) virus. Free virus particles able to bind CD4-positive cells are still produced in the presence of these compounds with only partial reduction of infectivity. We now report a method to score in parallel both the degree of antiviral activity and the effect on cell division of aminosugar derivatives. We find that (i) the compounds 1,4-dideoxy-1,4-imino-L-arabinitol and N-(5-carboxymethyl-1-pentyl)-1,5-imino-L-fucitol partially inhibit the cytopathic effect (giant cell formation, etc.) of HIV and yield of infectious virus; (ii) the compounds N-methyldeoxynojirimycin and N-ethyldeoxynojirimycin reduce the yield of infectious HIV by an order of four and three logarithms, respectively; and (iii) one compound, N-butyldeoxynojirimycin, of the 47 compounds previously screened reduces infectious viral particles by a logarithmic order greater than five at noncytotoxic concentrations. In addition, long-term growth of infected cells in the presence of N-butyldeoxynojirimycin gradually decreases the proportion of infected cells, leading to eventual elimination of HIV from culture. This result suggests that replication is associated with cytolysis. The ability to break the cycle of replication and reinfection has important implications in the chemotherapy of AIDS. PMID:3264071

    This paper discusses the importance of oral lesions as indicators of infection with human immunodeficiency virus (HIV) and as predictors of progression of HIV disease to acquired immunodeficiency syndrome (AIDS). Oral manifestations are among the earliest and most important indicators of infection with HIV. Seven cardinal lesions, oral candidiasis, hairy leukoplakia, Kaposi sarcoma, linear gingival erythema, necrotizing ulcerative gingivitis, necrotizing ulcerative periodontitis and non-Hodgkin lymphoma, which are strongly associated with HIV infection, have been identified and internationally calibrated, and are seen in both developed and developing countries. They may provide a strong indication of HIV infection and be present in the majority of HIV-infected people. Antiretroviral therapy may affect the prevalence of HIV-related lesions. The presence of oral lesions can have a significant impact on health-related quality of life. Oral health is strongly associated with physical and mental health and there are significant increases in oral health needs in people with HIV infection, especially in children, and in adults particularly in relation to periodontal diseases. International collaboration is needed to ensure that oral aspects of HIV disease are taken into account in medical programmes and to integrate oral health care with the general care of the patient. It is important that all health care workers receive education and training on the relevance of oral health needs and the use of oral lesions as surrogate markers in HIV infection. PMID:16211162

    Introduction: Oral lesions are among the earliest clinical manifestations of human immunodeficiency (HIV) infection and are important in early diagnosis and for monitoring the progression to acquired immunodeficiency syndrome (AIDS). The purpose of this study was to determine the prevalence of oral lesions and their relationship with a number of factors in HIV/AIDS patients attending an HIV center. Materials and Methods: A total of 110 HIV-positive patients were examined to investigate the prevalence of oral lesions according to the criteria established by the European Community Clearing House on Oral Problems Related to HIV Infection. An independent T-test was used for correlation of oral lesions with CD4+ count and a χ2 test was used for analysis of the relationship of co-infection with hepatitis B virus (HBV), sexual contact, route of transmission, history of drug abuse, and history of incarceration. Results: Most of the cases were male patients (82.7%). The mean age across all participants was 36.2±8.1 years. Rampant carries, severe periodontitis and oral candidiasis were the most notable oral lesions. Oral lesions were more prevalent in patients between 26–35 years of age. There was a significant difference between patients with and without pseudomembranous candidiasis and angular cheilitis according to mean level of CD4+. Conclusion: The most common oral presentations were severe periodontitis, pseudomembranous candidiasis and xerostomia. PMID:25745611

    The risk of human immunodeficiency virus (HIV) transmission following a bite injury is important to many groups of people. The first are those who are likely to be bitten as an occupational risk, such as police officers and institutional staff. Another group are represented by the victims and perpetrators of crimes involving biting, both in attack and defense situations. The possibility of these bites transmitting a potentially fatal disease is of interest to the physicians who treat such patients and the legal system which may have to deal with the repercussions of such a transmission. Bite injuries represent 1% of all emergency department admissions in the United States, and human bites are the third most common following those of dogs and cats. The worldwide epidemic of HIV and acquired immunodeficiency syndrome (AIDS) continues, with >5 million new cases last year and affecting 1 in 100 sexually active adults. A review of the literature concerning human bites, HIV and AIDS, HIV in saliva, and case examples was performed to examine the current opinion regarding the transmission of HIV via this route. A bite from an HIV-seropositive individual that breaks the skin or is associated with a previous injury carries a risk of infection for the bitten individual.

    Immunodeficiency-associated thrombocytopenic purpura (IDTP) is a feature of the acquired immunodeficiency syndrome--related complex. Current therapeutic modalities for IDTP include splenectomy and the administration of corticosteroids or other agents. Empiric treatment of IDTP has been analogous to that for immunologic thrombocytopenic purpura (ITP). The present report reviews 15 patients who underwent splenectomy for IDTP, demonstrates the successful use of surgical therapy, and defines our indications for splenectomy in the treatment of this disorder. Thirteen of 15 patients had initially failed to respond to steroid therapy. Fourteen patients (93%) initially responded to splenectomy, with platelet counts increasing to 150 X 10(9)/L (150,000/mm3) or greater. A continuing complete response was achieved in nine patients (60%) following splenectomy. After postsurgical adjunctive therapy, durable remission was achieved in 73% (11/15) of the patients. Complications occurred in three patients, and there were no deaths. The mean follow-up was 12.4 months. Splenectomy may be performed in the treatment of IDTP with acceptable morbidity and likelihood of response.

    Individuals searching for symptomatic relief or a potential cure are increasingly seeking and using nontraditional therapies for their various diseases. Little is known about the potential adverse effects that patients may encounter while undergoing these alternative treatments. Cesium chloride is an unregulated agent that has been reported to have antineoplastic properties. Cesium chloride is advertised as an alternative agent for many different types of cancers and can be purchased easily on the Internet. Recently, QT prolongation and polymorphic ventricular tachycardia were reported in several patients taking cesium chloride as alternative treatment for cancer. We report acquired QT prolongation and sustained monomorphic ventricular tachycardia in a patient who self-initiated and completed a course of cesium chloride as adjunctive treatment for brain cancer.

    Acquired epileptiform aphasia (AEA) is characterized by deterioration in language in childhood associated with seizures or epileptiform electroencephalographic abnormalities. Despite an extensive literature, discrepancies and contradictions surround its definition and nosological boundaries. This paper reviews current conceptions of AEA and highlights variations in the aphasic disturbance, age of onset, epileptiform EEG abnormalities, temporal course, and long-term outcome. We suggest that AEA, rather than being a discrete entity, is comprised of multiple variants that have in common the features of language regression and epileptiform changes on EEG. Viewed this way, we argue that AEA can be conceptualized on a spectrum with other epileptiform neurocognitive disorders that may share pathophysiological features. The implications of this viewpoint are discussed, with emphasis on parallels between the AEA variants and regressive autistic spectrum disorders.

    A 36-year-old woman developed hypokalemic metabolic alkalosis after anti SS-A antibody was found to be positive. Diuretic loading test results were compatible with Gitelman syndrome (GS). The patient had a heterozygous mutation in SLC12A3, which encodes for thiazide-sensitive NaCl cotransporter (NCCT). While the mutation may be responsible for a latent hypofunction of NCCTs, the underlying anti-SSA antibody-associated autoimmunity induced the manifestation of its hypofunction. To the best of our knowledge, this is the first report to demonstrate that anti SS-A antibody-associated autoimmunity may induce GS in a patient with a SLC12A3 heterozygous mutation. PMID:27803420

    A boy with a right congenital hemiparesis due to a left pre-natal middle cerebral artery infarct developed focal epilepsy at 33 months and then an insidious and subsequently more rapid, massive cognitive and behavioural regression with a frontal syndrome between the ages of 4 and 5 years with continuous spike-waves during sleep (CSWS) on the EEG. Both the epilepsy and the CSWS were immediately suppressed by hemispherotomy at the age of 5 years and 4 months. A behavioural-cognitive follow-up prior to hemispherotomy, an per-operative EEG and corticography and serial post-operative neuropsychological assessments were performed until the age of 11 years. The spread of the epileptic activity to the "healthy" frontal region was the cause of the reversible frontal syndrome. A later gradual long-term but incomplete cognitive recovery, with moderate mental disability was documented. This outcome is probably explained by another facet of the epilepsy, namely the structural effects of prolonged epileptic discharges in rapidly developing cerebral networks which are, at the same time undergoing the reorganization imposed by a unilateral early hemispheric lesion. Group studies on the outcome of children before and after hemispherectomy using only single IQ measures, pre- and post-operatively, may miss particular epileptic cognitive dysfunctions as they are likely to be different from case to case. Such detailed and rarely available complementary clinical and EEG data obtained in a single case at different time periods in relation to the epilepsy, including per-operative electrophysiological findings, may help to understand the different cognitive deficits and recovery profiles and the limits of full cognitive recovery.

    Four mouse monoclonal antibodies were developed after immunization with one human immunodeficiency virus (HIV) type 2 isolate and were tested for reactivity with different HIV-1, HIV-2, and simian immunodeficiency virus (SIV) isolates in an immunofluorescence assay and by immunological blot analysis. One of them, an anti-capsid (p24) antibody, called R1C7, reacted with all HIV-1, HIV-2, and SIV isolates tested, thus identifying an epitope shared by all HIV and SIV. Another anti-capsid antibody, named A4F6, reacted with three HIV-2 isolates (HIV-2NIH-Z, LAV-2Rod, and LK001 ST9), some SIV isolates (STLV-IIIAGM, SIV-251, and SIV-309), but no HIV-1 isolates. Two anti-matrix (p16) antibodies, named R5C4 and R5F6, reacted strongly only with the HIV-2 isolates. The use of these monoclonal antibodies for rapid discrimination and identification of acquired immunodeficiency syndrome-related retroviruses is discussed.

    We present a case of acquired dysfibrinogenemia caused by an autoantibody that inhibited fibrin polymerization in a patient previously diagnosed with MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis, stroke-like episodes). The patient showed prolonged PT, aPTT, and thrombin time. There was no factor deficiency but fibrinogen antigen and activity were decreased. ELISA for detection of fibrinogen antibodies were performed and IgG purified from the patient's plasma bound to fibrinogen more strongly than did control IgG, indicating the presence of a fibrinogen-specific antibody. Thrombin-mediated fibrin polymerization was severely impaired in the patient, although thrombin-induced fibrinopeptide A release was normal. Scanning electron microscopy was used to investigate the structure of fibrin clots and revealed many pores on the surface of patient's fibrin clots. Since MELAS is often associated with autoimmune disorders, a work-up for the presence of anti-fibrinogen antibody is necessary when bleeding tendency occurs in MELAS patients along with prolonged thrombin time.

    The life span of patients with primary and secondary immunodeficiency is increasing due to recent improvements in therapeutic strategies. While the incidence of primary immunodeficiencies (PIDs) is 1:10,000 births, that of secondary immunodeficiencies are more common and are associated with posttransplantation immune dysfunction, with immunosuppressive medication for human immunodeficiency virus or with human T-cell lymphotropic virus infection. After infection, malignancy is the most prevalent cause of death in both children and adults with (PIDs). PIDs more often associated with cancer include common variable immunodeficiency (CVID), Wiskott–Aldrich syndrome, ataxia-telangiectasia, and severe combined immunodeficiency. This suggests that a protective immune response against both infectious non-self-(pathogens) and malignant self-challenges (cancer) exists. The increased incidence of cancer has been attributed to defective elimination of altered or “transformed” cells and/or defective immunity towards cancer cells. The concept of aberrant immune surveillance occurring in PIDs is supported by evidence in mice and from patients undergoing immunosuppression after transplantation. Here, we discuss the importance of PID defects in the development of malignancies and the current limitations associated with molecular pathogenesis of these diseases and emphasize the need for further knowledge of how specific mutations can modulate the immune system to alter immunosurveillance and thereby play a key role in the etiology of malignancies in PID patients.

    The aim of this study was to review different animal models of Central Diabetes Insipidus, a neurobiological syndrome characterized by the excretion of copious amounts of diluted urine (polyuria), a consequent water intake (polydipsia), and a rise in the serum sodium concentration (hypernatremia). In rodents, Central Diabetes Insipidus can be caused by genetic disorders (Brattleboro rats) but also by various traumatic/surgical interventions, including neurohypophysectomy, pituitary stalk compression, hypophysectomy, and median eminence lesions. Regardless of its etiology, Central Diabetes Insipidus affects the neuroendocrine system that secretes arginine vasopressin, a neurohormone responsible for antidiuretic functions that acts trough the renal system. However, most Central Diabetes Insipidus models also show disorders in other neurobiological systems, specifically in the secretion of oxytocin, a neurohormone involved in body sodium excretion. Although the hydromineral behaviors shown by the different Central Diabetes Insipidus models have usually been considered as very similar, the present review highlights relevant differences with respect to these behaviors as a function of the individual neurobiological systems affected. Increased understanding of the relationship between the neuroendocrine systems involved and the associated hydromineral behaviors may allow appropriate action to be taken to correct these behavioral neuroendocrine deficits.

    Skin ulcer development in cutaneous leishmaniasis due to Leishmania braziliensis infection is associated with a mononuclear cell infiltrate and high levels of tumor necrosis factor (TNF). Herein, we show that despite the absence of Leishmania-driven TNF, a cutaneous leishmaniasis patient with acquired immunodeficiency syndrome developed a skin ulcer. The presence of mononuclear phagocytes and high levels of TNF, chemokine (C-C motif) ligand 2 (CCL2), and metalloproteinase-9 in tissue are identified as potential contributors to immunopathology observed in L. braziliensis-infected patients.

    Human immunodeficiency virus type 1 (HIV-1) has been clearly associated with a variety of new illnesses, including profound immunodeficiency (acquired immune deficiency syndrome [AIDS]), wasting syndromes (formerly termed AIDS-related complex [ARC]) and neurologic syndromes, including neuropathy, myelopathy and encephalopathy (often termed subacute encephalitis or AIDS dementia complex). HIV-1 preferentially infects T lymphocytes by binding to a membrane receptor protein, CD4, associated with helper function. The virus can also attack macrophages and, possibly, other cells such as neuronal cells, colonic epithelial cells and B lymphocytes. Infection of macrophages or monocytes may be involved in neurologic disease. Knowledge about HIV-1 has rapidly increased, and investigators have characterized its structure, ways in which it infects cells, replicates and is cytopathic for certain cells, and how the immune system responds to it. The ideal vaccine would prevent adsorption of the virus into the cell, but it is difficult to develop stable resistance because the virus has many antigenic patterns and mutates frequently. The results of vaccine trials in animals have not been promising, but work is being done with monoclonal antibodies. Antiviral therapies being investigated include those to prevent virus binding and entry, to inhibit reverse transcription, to inhibit the virus's life cycle and to restore immune competence in immunocompromised patients.

    Middle East respiratory syndrome coronavirus (MERS-CoV) cases without documented contact with another human MERS-CoV case make up 61% (517/853) of all reported cases. These primary cases are of particular interest for understanding the source(s) and route(s) of transmission and for designing long-term disease control measures. Dromedary camels are the only animal species for which there is convincing evidence that it is a host species for MERS-CoV and hence a potential source of human infections. However, only a small proportion of the primary cases have reported contact with camels. Other possible sources and vehicles of infection include food-borne transmission through consumption of unpasteurized camel milk and raw meat, medicinal use of camel urine and zoonotic transmission from other species. There are critical knowledge gaps around this new disease which can only be closed through traditional field epidemiological investigations and studies designed to test hypothesis regarding sources of infection and risk factors for disease. Since the 1960s, there has been a radical change in dromedary camel farming practices in the Arabian Peninsula with an intensification of the production and a concentration of the production around cities. It is possible that the recent intensification of camel herding in the Arabian Peninsula has increased the virus' reproductive number and attack rate in camel herds while the 'urbanization' of camel herding increased the frequency of zoonotic 'spillover' infections from camels to humans. It is reasonable to assume, although difficult to measure, that the sensitivity of public health surveillance to detect previously unknown diseases is lower in East Africa than in Saudi Arabia and that sporadic human cases may have gone undetected there.

  20. The link between abnormal calcium handling and electrical instability in acquired long QT syndrome--Does calcium precipitate arrhythmic storms?

    2016-01-01

    Release of Ca(2+) ions from sarcoplasmic reticulum (SR) into myocyte cytoplasm and their binding to troponin C is the final signal form myocardial contraction. Synchronous contraction of ventricular myocytes is necessary for efficient cardiac pumping function. This requires both shuttling of Ca(2+) between SR and cytoplasm in individual myocytes, and organ-level synchronization of this process by means of electrical coupling among ventricular myocytes. Abnormal Ca(2+) release from SR causes arrhythmias in the setting of CPVT (catecholaminergic polymorphic ventricular tachycardia) and digoxin toxicity. Recent optical mapping data indicate that abnormal Ca(2+) handling causes arrhythmias in models of both repolarization impairment and profound bradycardia. The mechanisms involve dynamic spatial heterogeneity of myocardial Ca(2+) handling preceding arrhythmia onset, cell-synchronous systolic secondary Ca(2+) elevation (SSCE), as well as more complex abnormalities of intracellular Ca(2+) handling detected by subcellular optical mapping in Langendorff-perfused hearts. The regional heterogeneities in Ca(2+) handling cause action potential (AP) heterogeneities through sodium-calcium exchange (NCX) activation and eventually overwhelm electrical coupling of the tissue. Divergent Ca(2+) dynamics among different myocardial regions leads to temporal instability of AP duration and - on the patient level - in T wave lability. Although T-wave alternans has been linked to cardiac arrhythmias, non-alternans lability is observed in pre-clinical models of the long QT syndrome (LQTS) and CPVT, and in LQTS patients. Analysis of T wave lability may provide a real-time window on the abnormal Ca(2+) dynamics causing specific arrhythmias such as Torsade de Pointes (TdP).
