    The International Planned Parenthood Medical Advisory Panel has developed recommendations to assist family planning associations in playing a more active role in the prevention and control of acquired immunodeficiency syndrome (AIDS). Of primary importance is an effective program of information and education aimed at communicating the following facts: AIDS is a fatal disease for which there is no cure; AIDS is spread by sexual intercourse, contaminated blood, and contaminated needles; an infected woman can transmit AIDS to her fetus during pregnancy; a monogamous sexual relationship is the surest way to avoid AIDS infection; condom use is good protection; an infected person can look and feel well, yet still be able to transmit the AIDS virus; and AIDS is not spread by ordinary contact with an infected person. Family planning associations should include information on AIDS in all existing IEC projects, as well as develop new materials. Among the target audiences for IEC activities are family planning workers, family planning clients, and the general public including youth, teachers, parents, employers, and national leaders. Special attention should be given to high-risk groups such as homosexual and bisexual men, hemophiliacs, male and female prostitutes, clients of sexually transmitted disease clinics, people with many sexual partners, illegal users of intravenous drugs, and the sexual partners of those in any of these groups. Wide promotion of condom use is a priority activity for family planning organizations. PMID:12340977

    A 33-year-old homosexual man with symptoms and signs of a focal brain process was subsequently found to have an acquired immune deficiency syndrome (AIDS) with biopsy-proven progressive multifocal leukoencephalopathy. This report reemphasizes the association of progressive multifocal leukoencephalopathy with AIDS and probably is best viewed as another example of an opportunistic CNS infection complicating deficient cell-mediated immunity.

    The acquired immune deficiency syndrome (AIDS) is a syndrome requiring unique knowledge of its versatile manifestations for accurate diagnosis and skillfull management of its numerous complications for successful treatment. The human T-cell lymphotropic virus type III (HTLV-III), a replication-complete virus, is now reported as the etiologic agent. The neurologic complications of AIDS cover the spectrum of neurologic diseases and usually have multiple causative factors, all of which should be appropriately managed. These complications can be successfully treated, although constant monitoring is required because recurrence is frequent. The neurologic complications are the second most frequent cause of death in AIDS patients. Tests that are usually reliable in diagnosing neurologic diseases may not be reliable in patients with AIDS. The management of AIDS is a multidisciplinary effort, and the neurologist should fulfill a role in the management team. ImagesFigure 1Figure 2Figure 3Figure 4 PMID:3334059

    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.

    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.

    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.

    A 34-year-old male prisoner with a history of intravenous drug abuse presented with fever, lymphadenopathy, weight loss, and recent onset of congestive heart failure. Serologic testing was positive for antibodies to human immune deficiency virus. There was intense myocardial uptake of gallium. Autopsy showed a primary immunoblastic lymphoma involving only the myocardium. While primary cardiac lymphoma is an extremely rare condition, the incidence may be higher in patients with acquired immune deficiency syndrome (AIDS) and should be suspected in cases with atypical cardiomyopathy.

    Rhodococcus equi, formerly known as Corynebacterium equi, was isolated repeatedly from the blood of two patients with the acquired immune deficiency syndrome (AIDS). Neither of the patients had pneumonia while they were bacteraemic, whereas pneumonia has been present in all previously reported cases of human infection with R equi. One of our patients had diarrhoea and the organism was isolated from a stool culture; the other patient had a large granulomatous soft tissue mass in his pelvis caused by R equi. Both isolates were resistant to penicillin and one produced a beta-lactamase. Both patients were treated with vancomycin but only one recovered. Images Figure PMID:3584508

    Non-Hodgkin's lymphoma (NHL) is designated as an acquired immune deficiency syndrome defining condition. Although uncommon, it is essential to be wary of this neoplasm since intraoral manifestations may be the first clinical manifestation of HIV disease. The gingiva is one of the rarest intraoral sites with a prevalence of 0.6%. Careful evaluation of patients presenting with solitary atypical gingival mass can lead to early detection of HIV disease. Here, we report a case of NHL manifesting as a gingival mass in a 45-year-old HIV-positive female patient. PMID:27190419

    Increased levels of 3% PEG precipitable circulating immune complexes (CIC) were found in healthy homosexual men, in homosexual patients with the acquired immune deficiency syndrome (AIDS), and in the AIDS related lymphadenopathy syndrome (LAS). The degree of CIC elevation increases from healthy homosexual men to LAS and AIDS. Patients suffering from AIDS associated with opportunistic infections had a more pronounced increase in CIC than patients with AIDS associated Kaposi's sarcoma. In LAS and AIDS the amount of CIC correlated with the degree of inversion of the T4/T8 lymphocyte ratio, whereas in healthy homosexual men with increased levels of CIC the T4/T8 ratio was not significantly altered. Laser nephelometric partial components analysis revealed that these complexes were of a complement poor subtype with low component levels of C4, C1q and C3c. IgM and IgG were found to be the major components. It is suggested that these CIC might represent a marker of the total antigenic burden of the immune system. Possibly, they are of prognostic and monitoring value for clinical handling of patients at risk for AIDS. PMID:3156700

    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.

    1994-01-01

    New drugs and therapies are continually emerging in an effort to delay the progression of human immunodeficiency virus (HIV)-positive status to acquired immune deficiency syndrome (AIDS). One such treatment is passive hyperimmune therapy (PHT), which was first researched and subsequently published in 1988. Passive hyperimmune therapy involves plasmapheresis of an asymptomatic HIV-positive donor with high p24 antibodies, no detectable p24 antigen, and a helper-inducer T-cell count greater than 400. The plasma is then pooled, sterilized, and administered to symptomatic HIV-positive patients as a monthly intravenous infusion in an effort to provide passive immunotherapy. In this article, an overview of PHT is provided, including benefits, adverse reactions, and other similar therapies available, so that the nurse who cares for HIV-positive patients can continue to be a significant source of information to them.

    Diarrhoea and malnutrition are common findings in patients with the Acquired Immune Deficiency Syndrome (AIDS). In this disease, enteropathy leads to fat and D-xylose malabsorption and chronic non-specific inflammation of the small bowel. Moreover, gastrointestinal infection can induce severe diarrhoea. Depletion in real body cell mass, body fat content, and weight loss have been observed. Nutritional therapy is mandatory when weight loss is 10% or greater. Enteral feeding is not easily achieved. Parenteral feeding including fat as a nonprotein calorie source improves general condition. The use of intravenous fat emulsions has been hypothesized to have several beneficial effects. Fluidisation of human immunodeficiency virus membranes by lipid emulsions through cholesterol extraction could decrease the infectivity of the virus. Long term intravenous nutrition may be more than a treatment for malabsorption and depletion; it may possibly have direct pharmacological effects. PMID:16837303

    Purpose To update information on cytomegalovirus (CMV) retinitis in patients with the acquired immune deficiency syndrome (AIDS) and to integrate information on its pathogenesis and clinical outcomes. Design Literature review. Methods Selected articles from the medical literature, particularly large epidemiologic studies, including the Johns Hopkins Cytomegalovirus Retinitis Cohort Study, the Longitudinal Study of the Ocular Complications of AIDS, and the Cytomegalovirus Retinitis and Viral Resistance Study, were reviewed. Clinical information is discussed in light of knowledge on CMV, its pathogenesis, and its interactions with human immunodeficiency virus (HIV). Results Cytomegalovirus uses several mechanisms to evade the immune system and establish latent infection in immunologically normal hosts. With immune deficiency, such as late-stage AIDS, CMV reactivates, is disseminated to the eye, and establishes a productive infection, resulting in retinal necrosis. HIV and CMV potentiate each other: CMV accelerates HIV disease, and CMV retinitis is associated with increased mortality. Randomized clinical trials have demonstrated the efficacy of treatments for CMV retinitis. Systemically-administered treatment for CMV retinitis decreases AIDS mortality. Highly active antiretroviral therapy (HAART), effectively suppresses HIV replication, resulting in immune recovery, which, if sufficient, controls retinitis without anti-CMV therapy. Resistant CMV, detected in the blood, correlates with resistant virus in the eye and is associated with worse clinical outcomes, including mortality. Host factors, including host genetics and access to care, play a role in the development of CMV retinitis. Conclusions Clinical outcomes of CMV retinitis in patients with AIDS are dependent on characteristics of the virus and host and on HIV–CMV interactions. PMID:21168815

    Significantly higher proportions of patients with acquired immune deficiency syndrome (AIDS) or lymphadenopathy syndrome (LAS) were positive for antibodies to cytomegalovirus (CMV) and herpes simplex virus (HSV) compared with control groups of commercial blood donors. In contrast, no differences were found in the incidence of individuals positive for antibodies to rubella in these groups of subjects. Of those positive for antibodies to CMV and HSV in each group, the mean antibody levels were significantly higher in AIDS-LAS patients compared with the controls. The entire distribution of antibody concentrations to CMV and HSV in AIDS patients was shifted upward, so that significantly more patients showed high values and significantly fewer showed low values, indicating hyperactive humoral immune responses to these viruses. In sharp contrast, the AIDS patients with antibody levels for rubella showed the same distribution of antibody levels as did two groups of controls. No correlation was found between concentrations of CMV and HSV antibodies in individual AIDS-LAS patients. PMID:3009534

    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.

    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.

    Responses to a lifestyle questionnaire among 13 patients with Kaposi's sarcoma and 18 with an opportunistic infection were compared with those of 29 symptom-free referred individuals. Odds ratios (OR) with 95% confidence limits were calculated as an estimate of risk. Significantly elevated odds ratios (P less than 0.05) were found for cigarette smoking (OR = 3.4), marijuana use (OR = 3.7), nitrite use (OR = 5.5), frequenting bathhouses (OR = 7.6), prior syphilis (OR = 3.4), and fist-rectal sexual practices (OR = 3.5). A response gradient for the risk estimates was found for marijuana use (OR = 2.7 for occasional, OR = 4.3 for frequent use); nitrites (OR = 4.0 for occasional; OR = 6.3 for frequent use); and prior syphilis (OR = 2.9 for one to two previous infections and 9.0 for three or more). We believe the evidence is now sufficient to recommend preventive practices which may reduce the male homosexual's risk for developing acquired immune deficiency syndrome, Kaposi's sarcoma, and/or opportunistic infections. These include cessation of cigarette smoking, marijuana use, and nitrite inhalation; reduction in number of anonymous sexual partners to decrease risk of sexually transmitted diseases; and avoidance of fisting.

    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. PMID:26699285

    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. PMID:21210240

    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. PMID:2596454

Knowledge of the geographical distribution of the HIV/AIDS epidemic is needed for the prevention and control of AIDS. Thus, the cumulative number of reported cases of HIV/AIDS from the period 1985-2013, and the incidence rate of AIDS in 2013 were determined. Spatial autocorrelation analysis and hotspot analysis were conducted using ArcGIS10.2 to explore the spatial distribution of the HIV/AIDS epidemic. Both the thematic map and the global spatial autocorrelation Moran's I statistics revealed a clustered distribution of the spatial pattern. A local spatial autocorrelation analysis indicated hotspots of AIDS incidence rate that were confined to the provinces of Guangxi, Yunnan and Sichuan. The hotspots encompassed Guangxi and Yunnan, while Henan Province displayed a negative autocorrelation with more variable numbers that included neighbouring regions. The Getis-Ord Gi* statistics identified 6 hotspots and 8 coldspots for the incidence of AIDS, and 7 hotspots and 1 coldspot for the cumulative number of reported cases of HIV/AIDS. The spatial distribution pattern of the HIV/AIDS epidemic in China is clustered, demonstrating hotspots located in the Southwest. Specific interventions targeting provinces with severe HIV/AIDS epidemic are urgently needed. PMID:27245799

    Enteric infections, chronic diarrhea frequently with no obvious etiology, and weight loss cause major morbidity and mortality in acquired immune deficiency syndrome (AIDS). Alterations in mucosal immunity may explain the increased incidence of enteric infections, and contamination of the upper small intestine with bacteria may be the cause of weight loss observed in these patients. To test this hypothesis we studied the mucosal T lymphocyte subset in duodenal mucosal biopsies in 14 AIDS and seven control patients. Duodenal fluid was also cultured for aerobic and anaerobic bacteria. There was a significant decrease among leu-3a T cells (helper/inducer) subset in AIDS. The proportion of mucosal T cells reacting with leu-2a (cytotoxic/suppressor) was significantly increased in AIDS patients. These patients also had a significant reversal of the normal mucosal helper/suppressor T cell ratio. There was no change in the number of leu-7 cells (cells mediate natural killer and antibody-dependent cellular cytotoxicity) as compared to controls. All patients with diarrhea and three of five patients without diarrhea had bacteria in their duodenal fluid. Mean number of organisms was 4.5 X 10(4)/ml. Cultures were negative in all control subjects. The results reveal that the abnormalities of T cell subpopulation in the blood of AIDS patients also occur in their duodenal mucosa. This immunological abnormality is associated with the bacterial colonization of upper gastrointestinal tract which may explain the diarrhea and weight loss observed in majority of our patients. The results also indicate that increased incidence of enteric infections in AIDS may be explained on the basis of altered mucosal immunity. PMID:2953237

    A 73-year-old heterosexual man developed a high-grade non-Hodgkin's lymphoma at the site of an ileostomy only 2 years after proctectomy for undetermined colitis not cured by previous colectomy. In fact, the early occurrence of this usually very late and rare complication of ileostomy was probably favored by the simultaneous presence of acquired immune deficiency syndrome (AIDS) due to repeated blood transfusions for refractory anemia with excess blasts. The intestinal location of the tumor, its high-grade malignancy and B-cell origin are all features of AIDS-related non-Hodgkin's lymphoma. This case report seems to be one of the rarely identified examples of the cooperation between general predisposing factors and local irritating agents at the origin of a malignant tumor.

    Introduction. Wernicke's encephalopathy is a well-described syndrome characterized by the classic triad of confusion, ataxia, and ophthalmoplegia. Wernicke's encephalopathy results from thiamine (vitamin B1) deficiency. Common causes include alcoholism and gastric disorders. Wernicke's has been described in patients with acquired immune deficiency syndrome (AIDS); however, given these patients' immunosuppressed state, the diagnosis of Wernicke's encephalopathy is not apparent. Case Presentation. A 31-year-old previously healthy male presented to the ER complaining of progressive dyspnea. Workup revealed HIV/AIDS and PCP pneumonia. He was treated and improved. On day 14 he became confused and developed nystagmus and ataxia. Considering his immunocompromised state, infectious and neoplastic etiologies topped the differential diagnosis. CT head was negative. Lumbar puncture was unremarkable. Brain MRI revealed increased T2 signal in the medial thalamus bilaterally. Intravenous thiamine was administered resulting in resolution of symptoms. Discussion. The classic triad of Wernicke's encephalopathy occurs in 10% of cases. When immunosuppressed patients develop acute neurologic symptoms infectious or neoplastic etiologies must be excluded. However, given the relative safety of thiamine supplementation, there should be a low threshold for initiating therapy in order to reverse the symptoms and prevent progression to Korsakoff dementia, which is permanent.

    Refractory and relapsing crytocococcosis in acquired immune deficiency syndrome (AIDS) patients have a poor prognosis. The risk factors for this complicated infection course were evaluated by comparing refractory and/or relapsing cryptococcosis in human immunodeficiency virus-coinfected patients (cohort 1) with another group of AIDS patients who adequately responded to antifungals (cohort 2). Except for one isolate of Cryptococcus gattii from a cohort 2 case, all other isolates were identified as Cryptococcus neoformans var. grubii, sex type α, genotype VNI, including Cryptococcus reisolated from the relapse or in the refractory state. No differences were observed with respect to Cryptococcus capsule size and in the melanin and phospholipase production. The cohort 1 patients presented higher prevalence of cryptococcemia, cerebral dissemination, chronic liver disease, and leucopenia, and have increased death rate. Apparently, the refractory and/or relapsing cryptococcosis in the AIDS patients were more related to the host and the extent of the infection than to the fungal characteristics. PMID:26928832

    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

    This report presents systematic clinical data regarding psychiatric diagnoses, personal and family psychiatric histories, and symptomatologic aspects of 90 consecutive human immunodeficiency virus (HIV)-seropositive and acquired immune deficiency syndrome (AIDS) patients, of whom slightly less than two thirds were at risk due to intravenous drug abuse. In addition, a comparison was made between the distribution patterns of these variables at various stages of HIV illness and related at-risk behaviors. Eighty-four percent of the patients met criteria for a spectrum of DSM-III-R diagnoses (mostly affective) that were associated with high rates of affective and alcohol abuse disorders among first-degree relatives. Mood disorders did not differ significantly between the two main groups at risk (intravenous drug users [IVDUs] v others) by gender, age, or stage of illness. The overall data from the rating scales show high levels of psychic and somatic anxiety in the early stages of illness, whereas cognitive symptoms, retardation, and disorientation are dominant in later stages. A noteworthy finding in this study is that many depressed patients demonstrated current and/or past hypomanic, hyperthymic, or cyclothymic features with no evidence of brain damage detectable by computed axial tomography (CAT). These temperamental attributes, which preceded HIV infection, may have served as risk factors for both drug abuse and impulsive sexual behavior in all types of at-risk groups. PMID:8826691

    The expression of HLA-DR (a class II histocompatibility antigen) on monocytes isolated from the peripheral blood of normal individuals and patients with acquired immune deficiency syndrome (AIDS) was investigated by the use of dual fluorescent staining and cytofluorometry. In animal models the absence of class II positive monocytes is linked to a failure of T cells to respond to antigens. We now report that patients with AIDS have a paucity of HLA-DR+ monocytes. The percentage of HLA-DR+ monocytes among eight normal individuals ranged from 49.3 to 95.0%+, and only one individual had less than 50% HLA-DR+ monocytes. HLA-DR expression on monocytes from homosexual male patients with lymphadenopathy was similar to that of normal subjects (range, 58.0 to 97.4%+). In contrast, seven of nine patients with AIDS had less than 50% HLA-DR+ monocytes (range, 13.4 to 78.8%+). The in vitro incubation of monocytes from AIDS patients with cloned human interferon-gamma resulted in an increase of the expression of HLA-DR to near normal levels. PMID:6439741

    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.

    Twenty patients with the acquired immune deficiency syndrome (AIDS) and suspected Pneumocystis carinii pneumonia were evaluated by /sup 67/Ga scintigraphy and fiberoptic bronchoscopy for initial diagnosis and response to therapy. Lung uptake of /sup 67/Ga was demonstrated in 100% of AIDS patients with P. carinii pneumonia, including those with subclinical infection. Fiberoptic bronchoscopy identified P. carinii in the bronchial washings of 100% of cases (19 patients), whereas only 13 of 16 (81%) patients had P. carinii in lung tissue obtained by transbronchial biopsy. Repeat fiberoptic bronchoscopy was performed in 16 of 20 patients. After 2 to 4 wk of therapy, P. carinii was identified in bronchial washings in 8 of 16 (50%) patients and in transbronchial biopsy in 1 of 10 (10%) patients examined. Bronchial washing has a higher yield than transbronchial biopsy in demonstrating P. carinii in patients with AIDS and may evolve as the procedure of choice in such patients. Based on the clinical course and results of /sup 67/Ga scintigraphy and fiberoptic bronchoscopy in AIDS patients with P. carinii pneumonia, optimal therapy may require at least 3 wk of treatment.

    No comparative studies exist for relapsed/refractory (rel/rfr) acquired immune deficiency syndrome (AIDS)-related lymphoma (ARL). To determine practices over the last decade and to assess the outcomes of salvage chemotherapy with curative intent and autologous stem cell transplant (ASCT), we retrospectively evaluated treatment outcomes in patients with rel/rfr ARL who were treated in 13 national AIDS Malignancy Consortium (AMC) sites between 1999 and 2008 (n = 88). The most commonly used second-line therapies were ICE (ifosfamide/carboplatin/etoposide, n = 34), dose adjusted EPOCH (etoposide/prednisone/vincristine/cyclophosphamide/doxorubicin, n = 17) and ESHAP (etoposide/methylprednisolone/cytarabine/cisplatin, n = 11). The odds of achieving a response were lower for those with non-Hodgkin lymphoma (NHL) than for those with HL and for those with primary refractory disease than for those with relapse. Overall survival (OS) was significantly longer for those with relapsed disease compared to those with refractory disease and for those with non-Burkitt NHL compared to those with Burkitt. OS was longer in patients who underwent ASCT compared to those who did not (1-year OS: 63.2% vs. 37.2%). However, among 32 patients (36%) who achieved a complete or partial response (CR/PR) after second-line therapy, 1-year OS was not different between the two groups (87.5% for ASCT vs. 81.8% for non-ASCT). Long-term survival in some patients with rel/rfr ARL may be possible without transplant, although transplant remains the standard of care for chemotherapy sensitive disease. PMID:22642936

    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.

    This case report describes new manifestations of the acquired immune deficiency syndrome (AIDS) in a promiscuous homosexual man. Investigation of upper gastrointestinal bleeding in the patient lead to discovery of a high-grade, small, noncleaved cell (Burkitt-like) gastroduodenal lymphoma with visceral and extralymphatic extension. Specific phenotyping of the lymphoma revealed that it was a monoclonal B cell lymphoma of mu kappa isotype. An in vitro cell line was established that was Epstein-Barr virus nuclear-associated antigen-positive. The lymphoma cells displayed a t(8;14) translocation similar to endemic African Burkitt lymphoma. Epstein-Barr virus genomes were identified in the lymphoma and an axillary lymph node biopsy specimen by molecular hybridization. These data strongly suggest that Epstein-Barr virus actively infected this patient. However, he showed normal Epstein-Barr virus-specific serologic responses, indicating an immune defect against the virus. PMID:2981469

    The immunomodulatory effects of a dietary supplement of purple sweet potato extract (PSPE) in LP-BM5 murine leukemia virus (MuLV)-induced immune-deficient mice were investigated. Mice were divided into six groups: normal control, infected control (LP-BM5 MuLV infection), positive control (LP-BM5 MuLV infection+dietary supplement of red ginseng 300 mg/kg), purple sweet potato water extract (PSPWE) (LP-BM5 MuLV infection+dietary supplement of PSPE 300 mg/kg), PSP10EE (LP-BM5 MuLV infection+dietary supplement of 10% ethanol PSPE 300 mg/kg), and PSP80EE (LP-BM5 MuLV infection+dietary supplement of 80% ethanol PSPE 300 mg/kg). Dietary supplementation began on the day of LP-BM5 MuLV infection and continued for 12 weeks. Dietary supplementation of PSPE inhibited LP-BM5 MuLV-induced splenomegaly and lymphadenopathy and attenuated the suppression of T- and B-cell proliferation and T helper 1/T helper 2 cytokine imbalance in LP-BM5 MuLV-infected mice. Dietary supplement of PSPE increased the activity of the antioxidant enzymes, superoxide dismutase and glutathione peroxidase. The data suggest that PSPE may ameliorate immune dysfunction due to LP-BM5 MuLV infection by modulating antioxidant defense systems. PMID:26076116

    In the age of antiretroviral therapy (ART), unraveling specific aspects of stigma that impede uptake and adherence to human immunodeficiency virus (HIV) services and the complex intersections among them might enhance the efficacy of stigma-reduction interventions targeted at the general public. Few studies have described community stigma in high HIV prevalence regions of Mozambique where program scale-up has been concentrated, but fear of stigma persists as a barrier to HIV service uptake. Principal components analysis of attitudinal data from 3749 female heads of households surveyed in Zambézia Province was used to examine patterns of agreement with stigmatizing attitudes and behavior toward people living with HIV. Inferences were based on comparison of factor loadings and commonality estimates. Construct validity was established through correlations with levels of knowledge about HIV transmission and consistency with the labeling theory of stigma. Two unique domains of community stigma were observed: negative labeling and devaluation (NLD, α = 0.74) and social exclusion (SoE, α = 0.73). NLD is primarily an attitudinal construct, while SoE captures behavioral intent. About one-third of the respondents scored in the upper tertile of the NLD stigma scale (scale: 0-100 stigma points) and the equivalent was 41.3% in the SoE stigma scale. Consistent with literature, NLD and SoE stigma scores were inversely correlated with HIV transmission route knowledge. In item level analysis, fear of being labeled a prostitute/immoral and of negative family affect defined the nature of stigma in this sample. Thus, despite ART scale-up and community education about HIV/acquired immune deficiency syndrome (AIDS), NLD and SoE characterized the community stigma of HIV in this setting. Follow-up studies could compare the impact of these stigma domains on HIV services uptake, in order to inform domain-focused stigma-reduction interventions. PMID:24274172

    The majority of adult cows in a certain dairy herd, were found to have very low levels of immunoglobulins (Igs) in their colostrum. This phenomenon was defined by us as Lactogenic-Immune-Deficiency-Syndrome (LIDS). The mean IgG levels were 44.5 and 57.2 mg ml-1 respectively (on two different occasions) as compared to that of a control group which was 103.4 mg ml-1. The levels of Igs in the colostra of heifers from the same herd were found to be higher than those of adult cows. The degree of LIDS was found to be closely related to the age of cows in the herd. The low levels of Igs in the colostra were not directly linked to their concentrations in the sera of the affected cows. The relatively low amount of IgA in the affected colostra suggests that the local production in the lymph tissue associated with the mammary glands is impaired as well. In order to investigate the etiology of the phenomenon, tests were carried out to reveal whether bovine leucosis virus (BLV) infection or immune complexes were involved in the pathogenesis of LIDS. The results were negative. The etiology of LIDS remains for the time being unknown. PMID:1632067

    Background We describe the first case of a patient with factitious disorder who closely simulated a primary immune deficiency disorder – Common Variable Immune Deficiency (CVID), by surreptitiously ingesting non-steroidal anti-inflammatory agents. Case description He was treated with several expensive and potentially dangerous drugs before the diagnosis was established through collateral information. In retrospect he did not meet the proposed new criteria for CVID. These criteria may prove useful in distinguishing cases of CVID from secondary hypogammaglobulinemia. Conclusion It is imperative clinicians recognise patients with factitious disorder at the earliest opportunity to prevent iatrogenic morbidity and mortality. PMID:24341706

    The simian immunodeficiency virus (SIV) of the common chimpanzee is widely acknowledged as the direct ancestor of HIV-1. There is increasing historical evidence that during the late 1950s, kidneys were routinely excised from central African chimpanzees by scientists who were collaborating with the polio vaccine research of Dr Hilary Koprowski, and sent - inter alia - to vaccine-making laboratories in the USA and Africa, and to unspecified destinations in Belgium. While there is no direct evidence that cells from these kidneys were used as a substrate for growing Dr Koprowski's oral polio vaccines, there is a startling coincidence between places in Africa where his CHAT vaccine was fed, and the first appearances in the world of HIV-1 group M and group-M-related AIDS. Because of the enormous implications of the hypothesis that AIDS may be an unintended iatrogenic (physician-caused) disease, it is almost inevitable that this theory will engender heated opposition from many of those in the scientific establishment, and those with vested interests.

    Pneumonia is the leading cause of death after acute spinal cord injury and is associated with poor neurological outcome. In contrast to the current understanding, attributing enhanced infection susceptibility solely to the patient's environment and motor dysfunction, we investigate whether a secondary functional neurogenic immune deficiency (spinal cord injury-induced immune deficiency syndrome, SCI-IDS) may account for the enhanced infection susceptibility. We applied a clinically relevant model of experimental induced pneumonia to investigate whether the systemic SCI-IDS is functional sufficient to cause pneumonia dependent on spinal cord injury lesion level and investigated whether findings are mirrored in a large prospective cohort study after human spinal cord injury. In a mouse model of inducible pneumonia, high thoracic lesions that interrupt sympathetic innervation to major immune organs, but not low thoracic lesions, significantly increased bacterial load in lungs. The ability to clear the bacterial load from the lung remained preserved in sham animals. Propagated immune susceptibility depended on injury of central pre-ganglionic but not peripheral postganglionic sympathetic innervation to the spleen. Thoracic spinal cord injury level was confirmed as an independent increased risk factor of pneumonia in patients after motor complete spinal cord injury (odds ratio = 1.35, P < 0.001) independently from mechanical ventilation and preserved sensory function by multiple regression analysis. We present evidence that spinal cord injury directly causes increased risk for bacterial infection in mice as well as in patients. Besides obvious motor and sensory paralysis, spinal cord injury also induces a functional SCI-IDS ('immune paralysis'), sufficient to propagate clinically relevant infection in an injury level dependent manner.

    Most autosomal genetic causes of childhood-onset hypogammaglobulinemia are currently not well understood. Most affected individuals are simplex cases, but both autosomal-dominant and autosomal-recessive inheritance have been described. We performed genetic linkage analysis in consanguineous families affected by hypogammaglobulinemia. Four consanguineous families with childhood-onset humoral immune deficiency and features of autoimmunity shared genotype evidence for a linkage interval on chromosome 4q. Sequencing of positional candidate genes revealed that in each family, affected individuals had a distinct homozygous mutation in LRBA (lipopolysaccharide responsive beige-like anchor protein). All LRBA mutations segregated with the disease because homozygous individuals showed hypogammaglobulinemia and autoimmunity, whereas heterozygous individuals were healthy. These mutations were absent in healthy controls. Individuals with homozygous LRBA mutations had no LRBA, had disturbed B cell development, defective in vitro B cell activation, plasmablast formation, and immunoglobulin secretion, and had low proliferative responses. We conclude that mutations in LRBA cause an immune deficiency characterized by defects in B cell activation and autophagy and by susceptibility to apoptosis, all of which are associated with a clinical phenotype of hypogammaglobulinemia and autoimmunity.

    We report the cases of 2 boys and 1 girl suffering from Netherton syndrome. Both boys presented with a non-bullous congenital erythroderma and were diagnosed early as Netherton syndrome with hair biopsies. Both had severe failure to thrive, signs of atopy, several episodes of bacterial infection, and rickets (with a high blood level of vitamin D in the first boy, and vitamin D deficiency in the second). In the third case, the pilar abnormality appeared at the age of 3 years. The girl had ichtyosis linearis circumflexa, failure to thrive and severe constipation. Netherton syndrome is a rare disorder characterized by severe ichtyosis, signs of atopy, immune deficiency and failure to thrive. The disease is severe and comprises many complications in early infancy. It is due to a genetic disorder of recessive autosomal transmission, and the gene, SPINK5, is located in the chromosome 5. Prenatal diagnosis is possible. Two of our patients had rickets, which has never been described in such patients population. PMID:15935629

    Background The approach to the diagnosis of Severe Combined Immunodeficiency Disease (SCID) and related disorders varies among institutions and countries. Objectives The Primary Immune Deficiency Treatment Consortium (PIDTC) attempted to develop a uniform set of criteria for diagnosing SCID and related disorders, and has evaluated the results as part of a retrospective study of SCID in North America. Methods Clinical records from 2000 through 2009 at 27 centers in North America were collected on 332 children treated with hematopoietic cell transplant (HCT), enzyme replacement therapy (ERT) or gene therapy (GT) for SCID and related disorders. Eligibility for inclusion in the study and classification into disease groups were established by set criteria and applied by an expert review group. Result Two hundred eighty-five (86%) of the patients were determined to be eligible and 47 (14%) were not eligible. Of the 285 eligible patients, 84% were classified as typical SCID; 13% were classified as leaky SCID, Omenn syndrome, or reticular dysgenesis; and 3% had a history of enzyme replacement or gene therapy. Detection of a genotype predicting a SCID phenotype was accepted for eligibility. Reasons for non-eligibility were failure to demonstrate either impaired lymphocyte proliferation or maternal T cell engraftment. Overall (n = 332) rates of testing were: proliferation to PHA 77%, maternal engraftment 35%, and genotype 79% (mutation identified in 62%). Conclusion Lack of complete laboratory evaluation of patients prior to HCT presents a significant barrier to definitive diagnosis of SCID and related disorders and prevented inclusion of individuals in our observational HCT study. This lesson is critical for patient care as well as the design of future, prospective treatment studies for such children, since a well-defined and consistent study population is important for precision in outcomes analysis.

    Acquired von Willebrand syndrome (aVWS) is a rare, but probably underestimated, bleeding disorder that mimics the congenital form of von Willebrand disease (VWD) in terms of laboratory findings and clinical presentation. However, unlike congenital VWD, it arises in individuals with no personal or family history of bleeding. AVWS occurs in association with a variety of underlying disorders, including lymphoproliferative disorders, myeloproliferative disorders and cardiovascular diseases. The main pathogenic, clinical, laboratory and therapeutic aspects of this syndrome are concisely reported in this review. PMID:16913181

    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 the utmost importance. PMID:1544049

    The pattern of distribution of gallium uptake in the thorax was investigated in patients (pts) with AIDS. Eleven pts (ages 18-53), all active homosexual males suspected of having acute pulmonary infection were studied. Ga lung scans were performed at 24-48 and/or 72 hrs. post injection. The diagnosis of AIDS was based on appropriate clinical and laboratory findings. The Ga activity in the lung was graded from zero = background to 4+ which is > liver activity. Eight of eleven pts have positive Ga scan while seven of eleven pts had positive CXR. Six pts had both positive CXR and Ga scan. One pt had a positive Ga scan with negative CXR, and one with positive CXR and negative Ga scan. The positive Ga scans included 3 pts with 4+ diffuse uptake, two pts with 2+ diffuse uptake, two pts with 1+ diffuse uptake, and two with hilar node uptake. Three pts have focal increased uptake superimposed on diffuse uptake. Two pts with 4+ diffuse uptake had mild abnormality on their CXR. One pt with 4+ uptake in the initial scan shows decreased activity on follow-up with clinical improvement after therapy. Thus, all but two pts with positive Ga scans had diffuse lung uptake. These two patients alone had B cell immunoblastic sarcoma and oral candidiasis. The pattern of Ga lung uptake in pts with AIDS reveal that a majority of positive scans are diffuse (6/8) and the intensity may suggest more active disease than CXR (2 normal) and, thus, the study may be useful in detecting changes from atypical pulmonary infection in this population.

    Purpose To evaluate the risk of cataract in the setting of AIDS. Design Prospective cohort study. Participants Subjects with AIDS free of ocular opportunistic infections throughout catamnesis. Methods During 1998–2008 inclusive, subjects ≥13 years of age were enrolled. Demographic characteristics and clinical characteristics were documented at enrollment and semiannually. Main Outcome Measures Cataract was defined as high-grade lens opacity observed by biomicroscopy and judged to be the cause of a best-corrected visual acuity worse than 20/40. Eyes that underwent cataract surgery during follow-up were considered to have developed cataract prior to the first visit when pseudophakia or aphakia was observed. Results Among 1,606 participants (3,212 eyes), at enrollment 1.9% (95% confidence interval (CI): 1.3%−2.7%) were observed to have cataract or prior cataract surgery. Among the 2,812 eyes initially free of cataract, and followed longitudinally (median follow-up=4.6 years), the incidence of cataract was 0.37%/eye-year (95% CI: 0.26%– 0.53%). In addition to age, significant cataract risk factors included prior cataract in the contralateral eye (adjusted hazard ratio (aHR)=21.6, 95% CI: 10.4–44.8), anterior segment inflammation (aHR=4.40, 95% CI: 1.64–11.9), prior retinal detachment (aHR=4.94, 95% CI: 2.21–11.0), and vitreous inflammation (aHR=7.12, 95% CI: 2.02– 25.0), each studied as a time-updated characteristic. Detectable HIV RNA in peripheral blood was associated with lower risk of cataract at enrollment (adjusted odds ratio=0.32, 95% CI: 0.12–0.80) but not of incident cataract (aHR=1.58, 95% CI: 0.90–2.76). After adjustment for other factors, neither the then current absolute CD4+ T cell count nor antiretroviral therapy status showed consistent association with cataract risk, nor did an additive diagnosis of other other co-morbidities. Compared to the available population-based studies that used similar definitions of cataract, the age-specific prevalence of cataract in our cohort was higher than in one of two such studies, and the age-specific incidence of cataract surgery was higher. Conclusions Our results suggest cataract may occur earlier among patients with AIDS free of ocular opportunistic infections than in the general population. Cataract risk was associated most strongly with age and with other ocular morbidity in this population. With improved survival, the burden of cataract likely will increase for persons with HIV/AIDS.

    Attention is focused on the segmentation of the audience (urban, rural, urban slum) and messages, and on how appropriate communication and educational strategies can be adopted to create awareness of AIDS among the African population. It is important to determine the scope, nature, and content of the message in addition to the delivery of these messages through proper channels. Channels of communication vary in reach and influence, and different segments of the population vary in the capacity to absorb information. Rural people are considered susceptible because of their penchant for continually using injections for treatment of any ailment; the source of concern is unsterilized needles and syringes. The semantics of AIDs is discussed to emphasize the problem of how to identify AIDs among the multiplicity of languages in individual countries. For instance, in Nigeria there may be 150-400 languages, and these languages lack systematically developed metalanguage and specialized vocabularies. The view that local language use must be one way, linear is accepted, and the difficulties surmounted. Local languages may be used to transmit information of a nontechnical nature. The literate minority should have access to detailed information on causes, modes of transmission, symptoms, treatment or management, but not everyone needs this extent of detail. The rural and urban residents should know about the incurability of the disease, the mode of transmission, its symptoms, and what should be done if someone is suspected of having an HIV infection. Already the Hausa of Nigeria have a term for AIDs, Karya-Garkuwa, which suggests a disease that breaks down the mechanism of the biological functioning of the body. Communicators must be knowledgeable and able to effectively transmit facts not myths. Of the 3 modes of transmission (sex, blood, mother to child), sexual transmission is the most important. Blood routes are through transfusions, contaminated blood products for hemophilia patients, contaminated needles and syringes of intravenous drug users, unsterilized needles and syringes used for medical treatment, knives for circumcision or body marking, razor blades in barber shops, and toothbrushes. All media should be used as well as community based informal and political channels. Traditional communication modes in rural areas are required. A multidisciplinary team of experts in modern and traditional media and instructional communication design and operation is needed. PMID:12317080

    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. PMID:26279989

    The Primary Immune Deficiency Treatment Consortium (PIDTC) is a collaboration of 41 North American centers studying therapy for rare primary immune deficiency diseases (PIDs), including severe combined immune deficiency (SCID), Wiskott-Aldrich syndrome (WAS), and chronic granulomatous disease (CGD). An additional 3 European centers have partnered with the PIDTC to study CGD. Natural history protocols of the PIDTC analyze outcomes of treatment for rare PIDs in multicenter longitudinal retrospective, prospective, and cross-sectional studies. Since 2009, participating centers have enrolled more than 800 subjects on PIDTC protocols for SCID, and enrollment in the studies on WAS and CGD is underway. Four pilot projects have been funded, and 12 junior investigators have received fellowship awards. Important publications of the consortium describe the outcomes of hematopoietic cell transplantation for SCID during 2000-2009, diagnostic criteria for SCID, and the pilot project of newborn screening for SCID in the Navajo Nation. The PIDTC Annual Scientific Workshops provide an opportunity to strengthen collaborations with junior investigators, patient advocacy groups, and international colleagues. Funded by the National Institute of Allergy and Infectious Diseases and the Office of Rare Diseases Research, National Center for Advancing Translational Sciences, the PIDTC has recently received renewal for another 5 years. Here we review accomplishments of the group, projects underway, highlights of recent workshops, and challenges for the future. PMID:27262745

    Central nervous system complications depicted by CT in ten patients with acquired immunodeficiency syndrome are described. Three patients had multifocal intra-axial enhancing lesions representing atypical brain abscesses (two with toxoplasmosis, one with candidiasis). A fourth patient with multifocal "ring" lesions whose biopsy was interpreted as suggestive of toxoplasmosis responded poorly to treatment. Following his death three months later of Pneumocystis carinii pneumonia, autopsy revealed primary intracerebral immunoblastic lymphoma. One patient had Kaposi sarcoma involving the right frontal lobe (seen as an enhancing mass on the CT scan). CT findings in the remaining five patients revealed mild to moderate enlargement of cerebrospinal fluid spaces (including ventricles and basal cisternae) as a result of cryptococcal meningitis in three patients and "aseptic" meningitis in two. The two patients in whom early biopsy confirmed toxoplasmosis responded well to anti-infective therapy, resulting in dramatic clinical recoveries. PMID:6622693

    Two HIV-positive male patients presented with a variety of symptoms including hemiparesis, unsteadiness, progressive loss of vision and poor memory. There were multiple non-enhancing lesions shown by CT scan in the white matter of the cerebral hemispheres. Specimens obtained by burr-hole biopsy showed the features of progressive multifocal leucoencephalopathy (PML) in both cases. Electron microscopy demonstrated round and rod shaped particles of papovavirus in the nuclei and cytoplasm of oligodendrocytes and in processes of astrocytes where abnormal and florid modes of viral replication were seen. Additional features observed were viral particles suggestive of an enterovirus in Case 1 and, in both specimens, massive membrane proliferation within both nuclei and cytoplasm of infected cells together with the presence of tubuloreticular structures (TRS) in the cytoplasm of endothelial cells. At post-mortem, the brain of patient 2 showed PML and HIV encephalitis. The presence of HIV was confirmed by immunohistochemical methods. We suggest that in AIDS patients the abnormality of the immune system induced by HIV causes abnormal replication patterns of papovavirus in the brain. In addition, these cases confirm the frequent occurrence in AIDS patients of TRS, now considered to be a marker for HIV. PMID:2555730

    Early in the human immunodeficiency virus (HIV) epidemic, infected patients presented to medical attention with striking abnormalities in each of the major blood cell lineages. The reasons for these derangements remain complex and multifactorial. HIV infects multipotent haematopoietic progenitor cells and establish latent cellular reservoirs, disturbs the bone marrow microenvironment and also causes immune dysregulation. These events lead to cytokine imbalances and disruption of other factors required for normal haematopoiesis. Activation of the reticulo-endothelial system can also result in increased blood cell destruction. The deleterious effects of medications, including first and second generation anti-retroviral agents, on haematopoiesis were well documented in the early years of HIV care; in the current era of HIV-care, the advent of newer and less toxic anti-retroviral drugs have had a more beneficial impact on haematopoiesis. Due to impaired regulation of the immune system and potential side effects of one or more anti-retroviral agents, there is also an increase in coagulation abnormalities such as thromboembolism, and less frequently, acquired disorders of coagulation including thrombotic thrombocytopenic purpura, immune thrombocytopenic purpura and acquired inhibitors of coagulation. In this article we review the epidemiology and aetiology of select non-oncological haematological disorders commonly seen in people living with HIV-acquired immune deficiency syndrome. PMID:26452169

    The Primary Immune Deficiency Treatment Consortium (PIDTC) is a network of 33 centers in North America that study the treatment of rare and severe primary immunodeficiency diseases (PID). Current protocols address the natural history of patients treated for Severe Combined Immunodeficiency (SCID), Wiskott-Aldrich Syndrome and Chronic Granulomatous Disease through retrospective, prospective and cross-sectional studies. The PIDTC additionally seeks to: encourage training of junior investigators; establish partnerships with European and other International colleagues; work with patient advocacy groups to promote community awareness; and conduct pilot demonstration projects. Future goals include the conduct of prospective treatment studies to determine optimal therapies for PID. To date, the PIDTC has funded two pilot projects: newborn screening for SCID in Navajo Native Americans; and B cell reconstitution in SCID patients following hematopoietic stem cell transplantation. Ten junior investigators have received grant awards. The PIDTC Annual Scientific Workshop has brought together consortium members, outside speakers, patient advocacy groups, and young investigators and trainees to report progress of the protocols and discuss common interests and goals, including new scientific developments and future directions of clinical research. Here we report the progress of the PIDTC to date, highlights of the first two PIDTC workshops, and consideration of future consortium objectives. PMID:24139498

    The Primary Immune Deficiency Treatment Consortium (PIDTC) is a network of 33 centers in North America that study the treatment of rare and severe primary immunodeficiency diseases. Current protocols address the natural history of patients treated for severe combined immunodeficiency (SCID), Wiskott-Aldrich syndrome, and chronic granulomatous disease through retrospective, prospective, and cross-sectional studies. The PIDTC additionally seeks to encourage training of junior investigators, establish partnerships with European and other International colleagues, work with patient advocacy groups to promote community awareness, and conduct pilot demonstration projects. Future goals include the conduct of prospective treatment studies to determine optimal therapies for primary immunodeficiency diseases. To date, the PIDTC has funded 2 pilot projects: newborn screening for SCID in Navajo Native Americans and B-cell reconstitution in patients with SCID after hematopoietic stem cell transplantation. Ten junior investigators have received grant awards. The PIDTC Annual Scientific Workshop has brought together consortium members, outside speakers, patient advocacy groups, and young investigators and trainees to report progress of the protocols and discuss common interests and goals, including new scientific developments and future directions of clinical research. Here we report the progress of the PIDTC to date, highlights of the first 2 PIDTC workshops, and consideration of future consortium objectives. PMID:24139498

    Acquired von Willebrand syndrome (aVWS) is a rare bleeding disorder with laboratory findings similar to those for congenital von Willebrand disease (VWD). However, unlike congenital VWD, it arises in individuals with no personal or family history of bleeding. aVWS occurs in association with a variety of underlying disorders, most frequently in lymphoproliferative disorders, myeloproliferative disorders, and cardiovascular diseases. Through an analysis of the more recent literature data, the pathophysiology and the clinical, laboratory, and therapeutic aspects of this syndrome are concisely reported in this review.

    The acquired immunodeficiency syndrome (AIDS) is a major health problem for gay men in the United States. About three fourths of all reported cases have occurred in this population, and the number is projected to double in the next year. In Manhattan and San Francisco, AIDS is now the leading cause of premature mortality in men aged 25 to 44 years who have never married. In a sample of a cohort of gay men enrolled in a San Francisco clinic, 2.7% of the men had the syndrome and 26% had related conditions in 1984. Antibody to human T-lymphotropic virus, type III/lymphadenopathy-associated virus was found in sera from 67% of the men, including 58% of asymptomatic men. Behavioral factors associated with an increased risk of AIDS include large numbers of sexual partners, receptive anal intercourse, and "fisting." The adoption of safer lifestyles is currently the basis of attempts to control the syndrome in gay men. PMID:2996396

    The skin is the largest organ of our body; it consists of the epidermis, dermis, hair follicles, sweat glands, blood vessels, and connective tissue matrix. Its main function is to act as a barrier to the outside world and protect us from infections. Any component of the skin is subject to insults from the environment and/or from within the body. Primary immune deficiency patients present with recurrent or prolonged infections not frequently seen in healthy individuals. Oftentimes, these infections involve the skin. Primary immune deficiency may also present with noninfectious cutaneous signs, such as eczema; erythroderma; granulomas; dysplasia of the skin, hair, nails, or teeth; pigmentary changes; angioedema; urticaria; vasculitis; or autoimmune skin disease due to immune dysregulation. Prompt recognition of the underlying diagnosis and initiation of treatment decrease morbidity. This review provides the reader with an up-to-date summary of the common dermatologic manifestations of primary immune deficiency diseases. PMID:25269404

    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. PMID:26577336

    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.

    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.

    Acquired von Willebrand syndrome (AVWS) is a rare acquired bleeding disorder similar to the congenital von Willebrand disease (VWD) in terms of laboratory findings. Diagnosis of AVWS can be very difficult, with treatment normally taking an empirical form. Although more than 200 cases have been reported since 1968, no retrospective or prospective studies are available on AVWS. Recently, an International Registry on AVWS, gathering data directly from worldwide Departments of Haematology-Oncology and Haemophilia Centres, has been organised by a group working on behalf of the Subcommittee on VWF in the Scientific Standardisation Committee (SSC) of International Society on Thrombosis and Haemostasis (ISTH). Information about an additional 211 AVWS patients is now available, with more detailed data on demography, type of haemorrhage, diagnostic tests for AVWS and management of bleeding episodes. The additional 211 AVWS cases are associated with lymphoproliferative (47%) or myeloproliferative (19%) disorders, cardiovascular diseases, neoplasia (7%) and other miscellaneous diseases (14%). Bleeding episodes of AVWS patients were managed by different compounds including desmopressin (22%), FVIII/VWF concentrates (26%) and high-dose immunoglobulin (10%), plasmapheresis (2%), steroids (5%) and immunosuppressive drugs (20%). Based on complied data, we can conclude that none of the therapeutic approaches proposed are 100% effective in all AVWS cases. Therefore, treatment must be customized for each patient according to the underlying disorder, as well as to the type and the severity of bleeding episode and must be targeted to each specific case.

    Blood and a variety of tissues from 97 patients with the acquired immunodeficiency syndrome (AIDS) and 25 with the AIDS prodrome were studied ultrastructurally. Tubuloreticular structures (TRS) were found in 85 per cent of the patients with AIDS and in 92 per cent of those with the prodrome. Test tube and ring-shaped forms (TRF), found in 41 per cent of the patients with AIDS and in 8 per cent of those with the prodrome, increased with disease progression. Among the patients with AIDS, as the number of sites examined per case increased, the incidence of TRS and TRF tended to approach 100 per cent, suggesting that they are present in all patients with AIDS. Other changes seen frequently were immunologic capping of blood lymphocytes, intramitochondrial iron in blood reticulocytes and marrow normoblasts, megakaryocytic immaturity and platelet phagocytosis, collections of membranous rings in hepatocytic cytoplasm, suggestive of non-A, non-B hepatitis, and proliferations and engorgement of hepatic Ito cells with lipid. The data suggest that TRS and TRF can be used as diagnostic and prognostic markers. PMID:3872253

    The aim of this study was to assess the mechanical characteristics of the respiratory system in patients with acquired immune deficiency syndrome (AIDS) and acute respiratory distress syndrome (ARDS) caused by Pneumocystis carinii pneumonia (PCP). In 12 mechanically ventilated patients, total respiratory system mechanics was assessed using the technique of rapid airway occlusion during constant flow inflation, and was partitioned into lung and chest wall components using the oesophageal balloon technique. We measured interrupter resistance (Rint), which mainly reflects airway resistance, additional resistance (deltaR) due to viscoelastic behaviour and time constant inequalities, and static elastance (Est). In addition, the static inflation volume-pressure (V-P) curve was assessed. In eight patients, computed tomography scans were performed within 2 days of the assessment of respiratory mechanics. Compared to values reported in the literature for normal subjects, Est and deltaR were markedly increased in AIDS patients with PCP, whilst Rint exhibited a relatively smaller increase. These changes, which involved only the lung and airways, were mainly due to the reduction of ventilated lung units, but additional factors were involved to cause independent modifications of lung stiffness, airway calibre, and viscoelastic properties. The changes in Rint, deltaR, and Est were similar to those observed in other studies on patients with ARDS of different aetiologies. At variance with common observations in the latter patients, none of the AIDS patients with PCP exhibited an inflection point on the static inflation V-P curve, suggesting little or no alveolar recruitment during lung inflation. This finding could be related to the distinctive histopathology of Pneumocystis carinii pneumonia. Indeed, computed tomography revealed homogeneous diffuse interstitial and alveolar infiltration rather than the dense, dependent opacities observed in other studies on acute respiratory

    Significant streptococcal (non-pneumococcal, non-enterococcal) bacteraemia was detected in 100 patients in two Health Districts of North Yorkshire in the decade 1978-1988. Patients with these infections accounted for 11% of the total 902 patients in the districts in whom bacteraemia was diagnosed during the period. Infection was most often seen with beta-haemolytic streptococci (52 patients) comprising Lancefield group A (Streptococcus pyogenes) (20 patients), group B (13), group C (5), group G (9), haemolytic Streptococcus milleri and non-groupable streptococci (5). The wide variety of serious infections included cellulitis, abscess, septicaemia, pneumonia, septic arthritis, necrotising fasciitis, acute endocarditis and mycotic aneurysm. Of these 52 patients, 21 (40%) died. alpha-Haemolytic streptococcal bacteraemia was diagnosed in 38 patients of whom 24 (63%) suffered from endocarditis and three (8%) died. Three of ten patients with non-haemolytic or anaerobic streptococcal bacteraemia died also. Six of the 100 patients with streptococcal bacteraemia had concomitant acute virus infections. Of the total 56 patients with infective endocarditis diagnosed in the districts during the period, streptococci were responsible in 30 (54%) of them. The predisposing factors, clinical features and outcome of the infections are described and discussed. PMID:2663996

    Current UK national standards recommend routine bacteriology surveillance in severe antibody-deficient patients, but less guidance exists on virology screening and viral infections in these patients. In this retrospective audit, we assessed the proportion of positive virology or bacteriology respiratory and stool samples from patients with severe, partial or no immune deficiency during a 2-year period. Medical notes were reviewed to identify symptomatic viral infections and to describe the course of persistent viral infections. During the 2-year period, 31 of 78 (39·7%) severe immune-deficient patients tested had a positive virology result and 89 of 160 (55.6%) had a positive bacteriology result. The most commonly detected pathogens were rhinovirus (12 patients), norovirus (6), Haemophilus influenzae (24), Pseudomonas spp. (22) and Staphylococcus aureus (21). Ninety-seven per cent of positive viral detection samples were from patients who were symptomatic. Low serum immunoglobulin IgA levels were more prevalent in patients with a positive virology sample compared to the total cohort (P = 0·0078). Three patients had persistent norovirus infection with sequential positive isolates for 9, 30 and 16 months. Virology screening of symptomatic antibody-deficient patients may be useful as a guide to anti-microbial treatment. A proportion of these patients may experience persistent viral infections with significant morbidity. PMID:25677249

    PubMed Central

    2010-01-01

    Common variable immunodeficiency is a rare immune deficiency, characterized by low levels of serum immunoglobulin G, A, and/or M with loss of antibody production. The diagnosis is most commonly made in adults between the ages of 20 and 40 years, but both children and older adults can be found to have this immune defect. The range of clinical manifestations is broad, including acute and chronic infections, inflammatory and autoimmune disease, and an increased incidence of cancer and lymphoma. For all these reasons, the disease phenotype is both heterogeneous and complex. Contributing to the complexity is that patient cohorts are generally small, criteria used for diagnosis vary, and the doses of replacement immune globulin differ. In addition, routines for monitoring patients over the years and protocols for the use of other biologic agents for complications have not been clarified or standardized. In the past few years, data from large patient registries have revealed that both selected laboratory markers and clinical phenotyping may aid in dissecting groups of subjects into biologically relevant categories. This review presents my approach to the diagnosis and treatment of patients with common variable immunodeficiency, with suggestions for the use of laboratory biomarkers and means of monitoring patients.

    Primary immune deficiencies (PIDs) are a growing group of over 230 different disorders caused by ineffective, absent or an increasing number of gain of function mutations in immune components, mainly cells and proteins. Once recognized, these rare disorders are treatable and in some cases curable. Otherwise untreated PIDs are often chronic, serious, or even fatal. The diagnosis of PIDs can be difficult due to lack of awareness or facilities for diagnosis, and management of PIDs is complex. This document was prepared by a worldwide multi-disciplinary team of specialists; it aims to set out comprehensive principles of care for PIDs. These include the role of specialized centers, the importance of registries, the need for multinational research, the role of patient organizations, management and treatment options, the requirement for sustained access to all treatments including immunoglobulin therapies and hematopoietic stem cell transplantation, important considerations for developing countries and suggestions for implementation. A range of healthcare policies and services have to be put into place by government agencies and healthcare providers, to ensure that PID patients worldwide have access to appropriate and sustainable medical and support services.

    Toll-like receptors (TLRs) recognize common microbial or host-derived macromolecules and have important roles in early activation of the immune system. Patients with primary immune deficiencies (PIDs) affecting TLR signaling can elucidate the importance of these proteins to the human immune system. Defects in interleukin-1 receptor-associated kinase-4 and myeloid differentiation factor 88 (MyD88) lead to susceptibility to infections with bacteria, while mutations in nuclear factor-κB essential modulator (NEMO) and other downstream mediators generally induce broader susceptibility to bacteria, viruses, and fungi. In contrast, TLR3 signaling defects are specific for susceptibility to herpes simplex virus type 1 encephalitis. Other PIDs induce functional alterations of TLR signaling pathways, such as common variable immunodeficiency in which plasmacytoid dendritic cell defects enhance defective responses of B cells to shared TLR agonists. Dampening of TLR responses is seen for TLRs 2 and 4 in chronic granulomatous disease (CGD) and X-linked agammaglobulinemia (XLA). Enhanced TLR responses, meanwhile, are seen for TLRs 5 and 9 in CGD, TLRs 4, 7/8, and 9 in XLA, TLRs 2 and 4 in hyper IgE syndrome, and for most TLRs in adenosine deaminase deficiency. PMID:25930993

    The use of gene therapy in the treatment of primary immune deficiencies (PID) has advanced significantly in the last decade. Clinical trials for X-linked severe combined immunodeficiency, adenosine deaminase deficiency (ADA), chronic granulomatous disease, and Wiskott-Aldrich syndrome have demonstrated that gene transfer into hematopoietic stem cells and autologous transplant can result in clinical improvement and is curative for many patients. Unfortunately, early clinical trials were complicated by vector-related insertional mutagenic events for several diseases with the exception of ADA-deficiency SCID. These results prompted the current wave of clinical trials for primary immunodeficiency using alternative retro- or lenti-viral vector constructs that are self-inactivating, and they have shown clinical efficacy without leukemic events thus far. The field of gene therapy continues to progress, with improvements in viral vector profiles, stem cell culturing techniques, and site-specific genome editing platforms. The future of gene therapy is promising, and we are quickly moving towards a time when it will be a standard cellular therapy for many forms of PID. PMID:27056559

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.

    Development of autoantibodies against coagulation factor VIII (FVIII) leads to a rare condition defined as acquired hemophilia (AH). If not diagnosed and treated early, AH may be associated with high mortality and morbidity. A 65-year-old woman presented with history of macrohematuria, acute renal failure, cardiogenic shock, and acute respiratory failure. Blood investigation revealed azotemia, prolonged activated partial thromboplastin time (aPTT), coagulation FVIII level of <1%, and presence of FVIII inhibitor. Echocardiography showed global hypokinesia and ultrasonography and computed tomography (CT) revealed bilateral hydroureteronephrosis. The final diagnosis was acquired hemophilia A, complicated by acute obstructive renal failure and cardiorenal syndrome (CRS) type 3. Patient was managed with mechanical ventilation, heparin-free hemodialysis, negative fluid balance, recombinant activated factor VII, and prednisolone. Hematuria was relieved, renal function improved, and cardiac function showed improvement on repeat echocardiography. Patient was discharged on prednisolone with subsequent follow ups. PMID:24501492

    Acquired long QT syndrome (LQTS) is a disorder of cardiac repolarization most often due to specific drugs, hypokalemia, or hypomagnesemia that may precipitate torsade de pointes and cause sudden cardiac death. Common presentations of the LQTS are palpitations, presyncope, syncope, cardiac arrest, and seizures. An abnormal 12-lead electrocardiogram obtained while the patient is at rest is the key to diagnosis. The occurrence of drug-induced LQTS is unpredictable in any given individual, but a common observation is that most patients have at least 1 identifiable risk factor in addition to drug exposure. The cornerstone of the management of acquired LQTS includes the identification and discontinuation of any precipitating drug and the correction of metabolic abnormalities, such as hypokalemia or hypomagnesemia. Most of the episodes of torsade de pointes are short-lived and terminate spontaneously. We propose a management protocol that could be useful for the daily practice in the emergency pediatric department to reduce the risk of acquired QT prolongation. PMID:24694881

    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

    A consultative meeting was convened by the World Health Organization in Geneva on 22-25 November 1983 to assess the present situation of AIDS (the acquired immunodeficiency syndrome) in the world and to encourage collaboration between the different nations affected by this disease. AIDS was first reported in the USA in 1981, but probably existed there as early as 1978. Soon after its recognition in the USA, similar cases were identified in other areas of the world. In most western European countries and Canada, the epidemiological pattern is very similar to that in the United States, the majority of cases being in homosexual men. In other areas such as equatorial Africa and the Caribbean, the pattern seems to be different with no identifiable risk factors for the majority of cases. The disease is manifested by opportunistic infections and/or selected malignancies, with apparent differences in the clinical presentation between the cases in North America and Europe, on the one hand, and those in the tropics. To date there is no treatment that has significantly improved the underlying cellular immune deficiency, and the mortality is very high. The etiology of AIDS is unknown, but the epidemiological pattern is most consistent with its being caused by a transmissible agent; retroviruses come on top of the list of candidate agents. Despite the unknown etiology and the lack of laboratory diagnostic tests, sufficient information is available to permit health authorities to make recommendations that may reduce appreciably the incidence of the disease. AIDS is an important health problem in a number of countries and has international implications. Collaborative laboratory, epidemiological and clinical research between countries is needed to accelerate control efforts. In the meantime, WHO will coordinate exchange of information among countries. ImagesFig. 1 PMID:6331905

    A 33-year-old Saudi woman presented with right hemiballismus of recent onset. Brain CT showed a left thalamo-subthalamic lesion which was thought initially to be a metastasis or a tuberculoma. The presence of severe subacute diarrhea, multiple lymphadenopathies and lymphopenia suggested an acquired immunodeficiency syndrome (AIDS). Tests for HIV-1 infection were positive and, despite the absence of antitoxoplasma antibodies in the serum, antitoxoplasmic treatment by pyrimethamine and sulfadiazine was given. One and a half month later, both abnormal movements and CT images had disappeared. The probable source of HIV infection was imported packed red blood cells received by the patient 5 years earlier. Toxoplasmic brain abscess associated with AIDS should be considered as a possible cause of hemiballismus in young adult even in the regions where AIDS is still infrequent. PMID:8303164

    We present a case of acquired von Willebrand syndrome (AVWS) due to a monoclonal gammopathy of undetermined significance. Initially this case was diagnosed as congenital von Willebrand disease (VWD); however, re-examination of the medical history rendered a congenital bleeding disorder unlikely. A normal plasma von Willebrand factor (VWF) propeptide level and a very short half-life of VWF after a test infusion with factor VIII/VWF concentrate confirmed the diagnosis AVWS. Two major surgical procedures were successfully managed using high-dose intravenous immunoglobulin. The differential diagnosis with congenital VWD and the diagnostic and therapeutic approaches of AVWS are discussed. We conclude that the diagnosis of AVWS relies primarily on clinical suspicion and a careful bleeding history. A correct diagnosis is essential for optimal perioperative management and treatment of bleeding episodes. PMID:16986130

    Approximately one-third of children with an acquired demyelinating syndrome (ADS) will be diagnosed with multiple sclerosis (MS), either at onset according to the 2010 McDonald criteria, or on the basis of clinical or MRI evidence of relapsing disease, in the majority of patients within 2-4 years. ADS in adolescents, female patients, and patients with polyfocal deficits is associated with the highest likelihood of MS, while children with acute disseminated encephalomyelitis, those with documented preceding infection, and ADS presentation in young children more commonly portends a monophasic outcome. While pediatric MS associates with similar genetic risk alleles as have been documented in adult-onset MS, such associations are not diagnostically valuable at the individual level. The presence of antibodies directed against aquaporin-4 strongly supports a diagnosis of neuromyelitis optica, and should be assayed in children manifesting with severe optic neuritis, longitudinally extensive myelitis, or brainstem/hypothalamic syndromes. Further research will determine whether other antibody signatures are indicative of relapsing demyelination distinct from MS. PMID:27572864

    Patients with the acquired immunodeficiency syndrome (AIDS) represent a novel referral population for rehabilitation services. Limited information about the rehabilitation needs of individuals with human immunodeficiency virus infection is available. We reviewed 51 consecutive patients with AIDS referred to a rehabilitation consult service. Common problems encountered included generalized deconditioning (27%) and neurologic dysfunction (45%). Neurologic presentations were diverse and included hemiparesis, diffuse cognitive dysfunction and dementia, myelopathy, myopathy and peripheral neuropathy. Other patients were referred for wound care as well as the management of the local effects of Kaposi's sarcoma, various musculoskeletal syndromes and new onset blindness. Problems identified included impaired mobility (76%), difficulty with self-care (57%), impaired cognition (29%) and uncontrolled pain (37%). Among the rehabilitation interventions utilized were therapeutic exercise (73%), gait aids (45%), bathroom and safety equipment (45%), orthotics (29%), vocational counseling (4%), pain management (29%) and whirlpool treatments (10%). Five patients were too ill or refused treatment. We conclude that AIDS patients referred for rehabilitation have a wide variety of physical deficits, demonstrate a considerable degree of functional impairment and may require multiple rehabilitation interventions.

    Acquired von Willebrand syndrome (AVWS) is an uncommon, underdiagnosed, and heterogeneous disease which is increasingly recognized as a cause of bleeding diatheses. Systemic lupus erythematosus (SLE) is an infrequent cause of AVWS. Herein, we report a case of AVWS diagnosed during the initial presentation of SLE in a previously healthy young man with no family history of bleeding diathesis who presented with worsening epistaxis, gastrointestinal bleeding, and anasarca. He was found to have severe anemia and prolonged activated partial thromboplastin time (aPTT) with severely decreased levels of von Willebrand factor (VWF) measurements in addition to markedly decreased factor VIII levels. Further evaluation revealed nephrotic syndrome and interstitial lung disease due to SLE. He initially received combination therapy with intravenous immunoglobulin (IVIG) and von Willebrand factor/factor VIII concentrates without significant improvement. Treatment with steroids, cyclophosphamide, and rituximab was followed by clinical improvement evidenced by cessation of bleeding. The short follow-up did not allow us to definitely prove the therapeutic effect of immunosuppressive treatment on AVWS in SLE patients. This case adds to the literature supporting the relationship between AVWS and SLE and highlights the importance of combination therapy in the treatment of severe AVWS as well as the role of IVIG, cyclophosphamide, and rituximab in AVWS associated with SLE.

    Community-acquired pneumonia remains a most widespread acute infectious disease of socio-economic significance all over the world. Up to 30% of the patients present with anemia responsible for the unfavourable prognosis and elevated mortality. Not infrequently, anemia is not diagnosed during the hospital stay und therefore remains uncorrected. Severe anemia results in enhanced hypercapnia and slowed maturation of red blood cells in the bone marrow which facilitates the development of ischemic syndrome. Hepcidin, a mediator of inflammation and iron-regulatory hormone, plays an important role in the clinical course of community-acquired pneumonia. Hepsidin production increases during inflammation; it suppresses erythtropoiesis and depletes the iron depot leading to so-called anemia of inflammation. Hypoxia and anemia activate erythtropoiesis, and the released erythropoietin inhibits hepsidin production. During pneumonia resolution, hepsidin promotes recovery from anemia by activating iron absorption. The curreni literature contains few data on the use of hepcidin as a diagnostic marker of anemia. The necessity oftreating anemia in patients with pneumonia under hospital conditions is a matter of discussion. Direct involvement of hepcidin in iron metabolism creates a prerequisite for the treatment of anemia. Medicamental suppression of its activity by stimulating erythtropoiesis can facilitate normalization of iron metabolism and restoration of hemoglobin level. PMID:27172725

    Acquired loss of functional von Willebrand factor (VWF) has been termed the acquired von Willebrand syndrome (AVWS). AVWS is a rare adult-onset bleeding diathesis that is clinically similar to congenital von Willebrand disease (VWD), and occurs with a variety of autoimmune, lymphoproliferative, or myeloproliferative disorders. We have identified four patients with AVWS in association with immunoglobulin light chain (AL) amyloidosis. These patients, lacking any pre-existing or family history of abnormal bleeding, developed cutaneous, mucosal, or gastrointestinal bleeding in the course of their disease without deficiency of clotting factor X or other factors; the activated partial thromboplastin time (aPTT) was prolonged in three out of the four cases. Despite normal VWF antigen levels, VWF ristocetin cofactor activity (VWF:RCo) was low. Electrophoresis patterns of high molecular weight (HMW) VWF multimers were abnormal in two of the four cases. Two of the patients were treated with high-dose intravenous melphalan followed by autologous stem cell transplantation (HDM/SCT) and achieved hematologic remission. In these two patients, the bleeding diathesis improved and the coagulation parameters normalized, confirming a causal relationship between the plasma cell dyscrasia and the AVWS. AVWS should be considered in AL amyloidosis patients with hemorrhagic diatheses and normal clotting factor levels. PMID:17205535

    Background Identifying genetic syndromes that lead to significant atopic disease can open new pathways for investigation and intervention in allergy. Objective To define a genetic syndrome of severe atopy, elevated serum IgE, immune deficiency, autoimmunity, and motor and neurocognitive impairment. Methods Eight patients from two families who had similar syndromic features were studied. Thorough clinical evaluations, including brain MRI and sensory evoked potentials, were performed. Peripheral lymphocyte flow cytometry, antibody responses, and T cell cytokine production were measured. Whole exome sequencing was performed to identify disease-causing mutations. Immunoblotting, qRT-PCR, enzymatic assays, nucleotide sugar and sugar phosphate analyses along with MALDI-TOF mass spectrometry of glycans were used to determine the molecular consequences of the mutations. Results Marked atopy and autoimmunity were associated with increased TH2 and TH17 cytokine production by CD4+ T cells. Bacterial and viral infection susceptibility were noted along with T cell lymphopenia, particularly of CD8+ T cells, and reduced memory B cells. Apparent brain hypomyelination resulted in markedly delayed evoked potentials and likely contributed to neurological abnormalities. Disease segregated with novel autosomal recessive mutations in a single gene, phosphoglucomutase 3 (PGM3). Although PGM3 protein expression was variably diminished, impaired function was demonstrated by decreased enzyme activity and reduced UDP-GlcNAc, along with decreased O- and N-linked protein glycosylation in patients’ cells. These results define a new Congenital Disorder of Glycosylation. Conclusions Autosomal recessive, hypomorphic PGM3 mutations underlie a disorder of severe atopy, immune deficiency, autoimmunity, intellectual disability and hypomyelination. PMID:24589341

    A retrospective review of a 24-month experience on the neurosurgical service at a large metropolitan hospital identified 33 patients with the acquired immunodeficiency syndrome (AIDS) who underwent diagnostic or therapeutic procedures. Intracranial mass lesions unresponsive to empiric medical therapy for presumed Toxoplasma gondii encephalitis underwent diagnostic biopsy in 22 patients: primary lymphoma was identified in 10 (45%) of these patients, and biopsy led to a treatable diagnosis in 16 of the 22. Patients with lymphoma were significantly more likely to have a single mass lesion than those with other diagnoses. The remaining 11 patients had a wide variety of neurologic disorders, including multiple strokes and transverse myelitis, aspergillous fungal infection of the base of the skull, primary lymphoma of the spinal cord, cat-scratch fever of the spine causing painful radiculopathy, hydrocephalus associated with cryptococcal meningitis, and progressive inflammatory peripheral neuropathy. Two patients had lymphoma within the subarachnoid space. Three patients with well-controlled AIDS underwent elective neurosurgical therapy for intractable radiculopathies due to herniated lumbar discs in 2 and cervical spondylosis in 1. Current treatment strategies in AIDS appear to have limited the need for brain biopsy, but the spectrum of neurologic disorders has broadened, requiring continued participation by neurologists and neurosurgeons. With improved long-term survival, the elective treatment of non-AIDS-related neurologic disorders in selected patients may be appropriate. Images PMID:8460506

    Myelodysplastic syndromes (MDS) are clonal myeloid disorders characterized by progressive peripheral blood cytopenias associated with ineffective myelopoiesis. They are typically considered neoplasms because of frequent genetic aberrations and patient-limited survival with progression to acute myeloid leukemia (AML) or death related to the consequences of bone marrow failure including infection, hemorrhage, and iron overload. A progression to AML has always been recognized among the myeloproliferative disorders (MPD) but occurs only rarely among those with essential thrombocythemia (ET). Yet, the World Health Organization (WHO) has chosen to apply the designation myeloproliferative neoplasms (MPN), for all MPD but has not similarly recommended that all MDS become the myelodysplastic neoplasms (MDN). This apparent dichotomy may reflect the extremely diverse nature of MDS. Moreover, the term MDS is occasionally inappropriately applied to hematologic disorders associated with acquired morphologic myelodysplastic features which may rather represent potentially reversible hematological responses to immune-mediated factors, nutritional deficiency states, and disordered myelopoietic responses to various pharmaceutical, herbal, or other potentially myelotoxic compounds. We emphasize the clinical settings, and the histopathologic features, of such AMD that should trigger a search for a reversible underlying condition that may be nonneoplastic and not MDS.

    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. PMID:26676359

    The acquired von Willebrand syndrome (AVWS) is a bleeding disorder that is frequently unrecognized or is misdiagnosed as von Willebrand disease. AVWS is characterized by structural or functional defects of von Willebrand factor (VWF) that are secondary to autoimmune, lymphoproliferative or myeloproliferative, malignant, cardiovascular, or other disorders. VWF abnormalities in these disorders can result from (1) antibody-mediated clearance or functional interference, (2) adsorption to surfaces of transformed cells or platelets, or (3) increased shear stress and subsequent proteolysis. Diagnosis can be challenging as no single test is usually sufficient to prove or exclude AVWS. Furthermore, there are no evidence-based guidelines for management. Treatments of the underlying medical condition, including chemo/radiotherapy, surgery, or immunosuppressants can result in remission of AVWS, but is not always feasible and successful. Because of the heterogeneous mechanisms of AVWS, more than one therapeutic approach is often required to treat acute bleeds and for prophylaxis during invasive procedures; the treatment options include, but are not limited to, desmopressin, VWF-containing concentrates, intravenous immunoglobulin, plasmapheresis or recombinant factor VIIa. Here, we review the management of AVWS with an overview on the currently available evidence and additional considerations for typical treatment situations. PMID:21540459

    Left ventricular assist devices (LVAD) provide cardiac support for patients with end-stage heart disease as either bridge or destination therapy, and have significantly improved the survival of these patients. Whereas earlier models were designed to mimic the human heart by producing a pulsatile flow in parallel with the patient's heart, newer devices, which are smaller and more durable, provide continuous blood flow along an axial path using an internal rotor in the blood. However, device-related hemostatic complications remain common and have negatively affected patients' recovery and quality of life. In most patients, the von Willebrand factor (VWF) rapidly loses large multimers and binds poorly to platelets and subendothelial collagen upon LVAD implantation, leading to the term acquired von Willebrand syndrome (AVWS). These changes in VWF structure and adhesive activity recover quickly upon LVAD explantation and are not observed in patients with heart transplant. The VWF defects are believed to be caused by excessive cleavage of large VWF multimers by the metalloprotease ADAMTS-13 in an LVAD-driven circulation. However, evidence that this mechanism could be the primary cause for the loss of large VWF multimers and LVAD-associated bleeding remains circumstantial. This review discusses changes in VWF reactivity found in patients on LVAD support. It specifically focuses on impacts of LVAD-related mechanical stress on VWF structural stability and adhesive reactivity in exploring multiple causes of AVWS and LVAD-associated hemostatic complications.

    Haematological abnormalities are common in systemic lupus erythematosus (SLE). In some cases of acquired von Willebrand syndrome (AvWS), von Willebrand disease (vWD) is associated with autoimmune or lymphoproliferative disorders. In this study, we describe a 36-year-old woman with SLE and AvWS. The patient was referred to our hospital because of easy bruisability and recurrent vaginal bleeding. She had no history of bleeding tendency and no family history of bleeding diathesis, but she had a history of recurrent arthralgia, photosensitivity and sicca symptoms. Tests for antinuclear, anti-double stranded DNA, anticardiolipin and anti-beta2-glycoprotein I antibodies were all positive. Analysis of haemostatic parameters showed complete absence of von Willebrand factor ristocetin cofactor (vWF:Rco), von Willebrand antigen (vWF:Ag) and ristocetin-induced platelet aggregation (RIPA). Electrophoretic analysis of plasma showed a complete absence of high-molecular weight vWF multimer. The presence of antibody to vWF was detected by enzyme linked immunosorbent assay (ELISA). Treatment with corticosteroids improved SLE symptoms and corrected bleeding diasthesis. Also, the multimeric patterns of vWF became normalised and anti-vWF antibody disappeared. These findings indicated that this patient had SLE associated with AvWS, which was ameliorated by corticosteroid treatment. PMID:18755868

    The congenital disorders of immune competence are known as primary immunodeficiencies (PID) and are mainly characterized by a pathological susceptibility to infection. These infections are mostly of time repetitive and drug resistant in nature. The number of infected infants has reached over 200 and is on the increase. Additionally, clinical severity of the disease has been confirmed to be extensive. The increasing number of these severe PIDs is due to the lack of specific as well as efficient management avenues. New assays and concepts for newborn screening of severe primary immune deficiencies are being explored and the present review focused on these new upcoming strategies for improved screening of neonates.

    Common variable immune deficiency (CVID) and chronic granulomatous disease (CGD) are two of the well-characterized primary immune deficiencies with distinct pathologic defects. While CVID is predominantly a disorder of the adaptive immune system, in CGD, innate immunity is impaired. In both syndromes, the clinical manifestations include an increased susceptibility to infections and a number of non-infectious, inflammatory conditions including systemic autoimmunity, as well as organ-specific pathology. Among the organ-associated disorders, gastrointestinal (GI) manifestations are one of the most intractable. As such, non-infectious inflammatory disorders of the GI tract are clinically challenging as they have protean manifestations, often resembling inflammatory bowel disease (IBD) or celiac disease, are notoriously difficult to treat, and hence are associated with significant morbidity and mortality. Therefore, assessing the pathogenesis and defining appropriate therapeutic approaches for GI disease in patients with CVID and CGD is imperative. PMID:26951230

    The field of Primary Immune Deficiency Disorders (PIDD) has advanced rapidly over the past several years with over 200 different gene mutations defined. With the recent institution of newborn screening for T cell deficiencies in many states and earlier recognition of the signs and symptoms of patients with immune deficiency, it is now apparent that PIDD is not as "rare" as was originally thought several decades ago. With the earlier recognition of patients with recurrent infections and various immune perturbations, advancements in the treatment of these immune deficiency disorders have led to enhanced survival and quality of life. In this issue, the diagnosis of PIDD through laboratory testing and skin manifestations is reviewed. The more recently described cellular immune deficiencies, selective immune deficiencies, and advances in the use of bone marrow transplantation in the correction of some of these immune deficiencies are discussed.

    To help clinicians better assess and treat functional disabilities in persons with acquired immunodeficiency syndrome (AIDS), the authors estimate empirical relations among biologic and physiologic variables, symptoms, and physical functioning in persons with AIDS. The sample of 305 persons with AIDS for this cross-sectional analysis came from three sites in Boston, Massachusetts: a hospital-based group practice, a human immunodeficiency virus clinic at a city hospital, and a staff-model health maintenance organization. Physical functioning, 10 AIDS-specific symptoms, and mental health were assessed by interview. Clinical diagnoses, comorbidities, health habits such as smoking, laboratory results, and selected medication use were assessed by chart review. Significant predictors of physical functioning P < 0.01, R2 = .58) in a multivariable regression model included energy/fatigue, neurologic symptoms, fever symptoms, a lower hemoglobin level, and current non-pneumonia bacterial infection. Ninety-six percent of the explained variance in physical functioning was accounted for by three symptom complexes: energy/fatigue, neurologic symptoms, and fever symptoms. Significant predictors of energy/fatigue in multivariable models included poorer mental health, lower white blood cell count, longer time since diagnosis, and weight loss (P < 0.01, R2 =.36). Significant predictors of neurologic symptoms included poorer mental health, weight loss, and no zidovudine use (P < 0.001, R2 = .30). Predictors of fever symptoms included poorer mental health, no zidovudine use, weight loss, and history of asthma or chronic obstructive pulmonary disease (P < 0.05, R2 = .25). In conclusion, symptom reports were strong predictors of physical functioning. Poorer mental health and weight loss were correlated consistently with worse symptoms, and not using zidovudine was correlated with worse neurologic and fever symptoms. These variables, and the others the authors identified, may represent

  14. Diagnosis and treatment of acquired von Willebrand syndrome.

    Acquired von Willebrand syndrome (AVWS) is a rare bleeding disorder that is characterized by structural or functional alterations in von Willebrand factor (VWF) caused by a range of lymphoproliferative, myeloproliferative, cardiovascular, autoimmune, and other disorders. The pathogenic mechanisms responsible for the VWF abnormalities depend on the underlying condition, but include clearance due to binding of paraproteins, inhibition of VWF, adsorption to the surface of platelets, increased fluid shear stress, and resultant proteolysis or, more rarely, decreased synthesis. The diagnosis and treatment of AVWS are complicated by the need for multiple laboratory tests and the management of bleeding risk in a typically elderly population with serious underlying conditions that predispose towards thrombosis. Recently developed diagnostic algorithms, based on standard laboratory assays, may assist clinicians with the diagnostic workup and help differentiate between AVWS and von Willebrand disease (VWD) types 1 and 2. AVWS should be considered in all patients with new-onset bleeding whenever laboratory findings suggest VWD, particularly in the presence of an AVWS-associated disorder. AVWS testing is also recommended prior to surgery or an intervention with a high risk of bleeding in any individual with an AVWS-associated disorder. Treatment of the underlying condition using immunosuppressants, surgery, or chemotherapy, can lead to remission of AVWS in some individuals and should always be considered. Strategies to prevent and/or treat bleeding episodes should also be in place, including the use of VWF-containing factor VIII concentrates, desmopressin and tranexamic acid. Treatment success will depend largely on the underlying pathogenesis of the disorder. PMID:23439003

    Abdominal computed tomography (CT) was performed in 31 patients with Kaposi sarcoma (KS) related to acquired immunodeficiency syndrome (AIDS), three patients with classic KS, and 12 patients with the newly described lymphadenopathy syndrome (LNS). The frequency, distribution, and appearance of lymphadenopathy and splenomegaly were similar in the AIDS-related KS and LNS groups. Rectal and perirectal disease was identified in 86% of homosexual men studied; rectal KS could not be distinguished from proctitis on CT criteria alone. No CT abnormalities were seen in patients with classic KS. The CT demonstration of retroperitoneal, mesenteric, or pelvic adenopathy or of rectal or perirectal disease in patients with AIDS-related KS is not necessarily indicative of widespread involvement with the disease.

    The acquired von Willebrand syndrome (AvWS) is a rare bleeding disorder with laboratory findings similar to those of congenital von Willebrand disease (vWD). Despite the numerous cases reported in the literature until 1999 (n = 266), large studies on AvWS are not available. Moreover, diagnosis of AvWS has been difficult and treatment empirical. These considerations prompted us to organize an international registry. A questionnaire, devised to collect specific information on AvWS, was sent to all the members of the International Society on Thrombosis and Haemostasis (ISTH), who were invited to respond if they had diagnosed cases with the AvWS cases. 156 members answered the questionnaire and 54 of them sent information on 211 AvWS cases from 50 centers. Data were compared with those already published in the literature and 25 cases already described or not correctly diagnosed were excluded. The 186 AvWS cases that qualified for the registry were associated with lymphoproliferative (48%) and myeloproliferative disorders (15%), neoplasia (5%), immunological (2%), cardiovascular (21%) and miscellaneous disorders (9%). Ristocetin cofactor activity (vWF:RCo) or collagen binding activity (vWF:CBA) were usually low in AvWS (median values 20 U/dL, range 3-150), while factor VIII coagulant activity was sometimes normal (median 25 U/dL, range 3-191). FVIII/vWF inhibiting activities were present in only a minority of cases (16%). Bleeding episodes in AvWS were mostly of mucocutaneous type (68%) and were managed by DDAVP (32%), FVIII/vWF concentrates (37%), intravenous immunoglobulins (33%), plasmapheresis (19%), corticosteroids (19%) and immunosuppressive or chemotherapic agents (35%). Based upon the data of this international registry, it appears that AvWS is especially frequent in lympho- or myeloproliferative and cardiovascular diseases. Therefore, AvWS should be suspected and searched with the appropriate laboratory tests especially when excessive bleeding occurs in

    Primary immune deficiency diseases (PIDs) are a heterogeneous group of inherited diseases characterized by variable genetic immune defects, conferring susceptibility to recurrent infections. They have a vast array of manifestations some of which involve the gastrointestinal and hepatobiliary systems. These complications can be the consequence of five different factors, namely, infection, autoimmune process, unregulated inflammation, malignancies and complications of therapeutic intervention. They may precede the PID diagnosis and, once developed, they pose high risk of morbidity. Untrained clinicians may treat these manifestations only at the level of their presentation, leaving the PIDs dangerously undiagnosed. In fact, early diagnosis of PIDs and accompanied gastrointestinal and hepatic complications clearly require appropriate treatment, and in-turn lead to an improved quality of life for the patient. To improve the awareness of gastroenterologists and related health care providers about these diseases, we have reviewed herein the complications of different PIDs focusing on gastrointestinal and hepatic manifestation.

    The paper presents a microflora analysis of a 5-year-old male child with severe combined immune deficiency who was delivered by Caesarean section and continuously maintained in an isolator. Despite precautions, it was found that the child had come in contact with at least 54 different microbial contaminants. While his skin autoflora was similar to that of a reference group of healthy male adults in numbers of different species and the number of viable cells present per square centimeter of surface area, the subject's autoflora differed from the reference group in that significantly fewer anaerobic species were recovered from the patient's mouth and feces. It is suggested that the child's remaining disease free shows that the reported bacteria are noninvasive or that the unaffected components of the child's immune defense mechanisms are important.

    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.

    Aim: Immunoglobulin replacement therapy is required to reduce the frequency and severity of infections in patients with primary antibody deficiencies. Immunoglobulin G (IgG) can be administered intramuscularly, intravenously or subcutaneously. We aimed to evaluate the efficacy, dose adjustment and adverse events in subcutaneous immunoglobulin therapy by retrospectively presenting the records of 16 patients who received subcutaneous immunoglobulin therapy. Material and Methods: The demographic findings, clinical and laboratory findings, subcutaneous immunoglobulin dosage and dose frequency, infusion time, area and methods, adverse events and frequency of infections were obtained from patient files and recorded. Results: Sixteen patients (seven female, nine male) aged between 0–33 years who were diagnosed with primary immune deficiency and treated with subcutaneous immunoglobulin were enrolled. All patients had been receiving intravenous imunoglobulin (5–10%) at a dose of 0.33–1.25 gr/kg/dose with two-four week intervals before subcutaneous immunoglobulin. Subcutaneous immunoglobulin (10%) was administered at a dose of 0.03–0.43 gr/kg/dose with one-two week intervals. No significant difference was found between serum through IgG levels before administration of intravenous imunoglobulin and steady state IgG levels during subcutaneous immunoglobulin therapy. When five patients whose serum through IgG levels were below 600 mg/dL were evaluated, however, a significant increase was found in steady state IgG levels with subcutaneous immunoglobulin therapy (p=0.043). In a ten-month follow-up period, seven infections were observed in four patients (three upper respiratory infectons, two lower respiratory tract infections and three acute gastroenteritis). No acute severe bacterial infection was observed. Local advers reaction was reported in only 10 of 180 infusions (6%). No serious adverse events were reported. All 16 patients were willing to continue IgG replacement

    Infectious complications constitute the second most common cause of mortality and a main cause of morbidity in beta-thalassemia. Besides the high risk of blood-borne infections associated with multiple transfusions, the increased susceptibility of these patients to infectious diseases has been attributed to a coexistent immune deficiency. Immune abnormalities have also been held responsible for the frequent occurrence of malignancies in beta-thalassemia, especially leukemia and lymphomas. Recent studies on immune competence in beta-thalassemia have revealed numerous quantitative and functional defects, involving T and B lymphocytes, immunoglobulin production, neutrophils and macrophages, chemotaxis, and phagocytosis, as well as the complement system. Regarding pathogenesis, iron overload, a primary complication of both thalassemia itself and transfusion therapy, is thought to be the main precipitating mechanism, due to the important immunoregulatory properties of iron and its binding proteins; iron excess may derange the immune balance in favor of the growth of infectious organisms. Other factors include multiple transfusions, associated with constant allo-antigenic stimulation, as well as with transmission of immunosuppressive viruses; splenectomy, resulting in increased susceptibility to infections by encapsulated bacteria and to immune system modifications; low levels of zinc, another immune regulator; iron chelation therapy, which predisposes to serious infections by yersinia species; and the circulation of abnormal native thalassemic erythrocytes, forming another permanent immune stimulus. Thus surveillance for infections in patients with beta-thalassemia is crucial, while further studies are warranted on immune function abnormalities and the implicated mechanisms. PMID:12552254

    The frequency and pathophysiology of hyponatremia were studied in the acquired immunodeficiency syndrome. Of 71 hospitalized patients surveyed retrospectively, hyponatremia was observed in 37 (52%). Of 48 patients studied prospectively, 27 (56%) were hyponatremic. In 16 hyponatremic patients, volume status; serum and urine osmolalities; renal, adrenal, and thyroid function; and plasma vasopressin levels were assessed. Urine osmolalities were inappropriately elevated relative to serum osmolalities. Four patients had moderate renal insufficiency. Plasma vasopressin levels, measured by radioimmunoassay, were elevated in 15 patients, with the highest levels seen in patients who died. Hyponatremia of multiple etiologies occurred in a majority of inpatients with the acquired immunodeficiency syndrome, often following the administration of hypotonic fluids, and was associated with a 30% (8/27) short-term mortality.

    Severe combined immunodeficiency (SCID) represents a syndrome comprising the most severe forms of inherited immunodeficiencies. Defects in cytokine signaling pathways can result in impaired development of lymphoid cells and/or defective functioning of these cells, and most cases of SCID result from defective signaling through the common cytokine receptor g chain (g(c)) or associated molecules and signaling pathways. Studies of these patients and the analysis of gene-targeted mice provide insight into the underlying signaling defects in inherited immunodeficiencies. The identification of the genetic defects in humans with SCID provides the basis for future therapies for these patients. More subtle deficiencies in cytokine signaling have also been found as causes of other forms of immunodeficiency, and the knowledge learned could lead to novel approaches to antimicrobial therapy.

    Diagnostic bone marrow aspiration, biopsy, and culture are useful procedures in the evaluation of patients with suspected or proven acquired immunodeficiency syndrome (AIDS) who are febrile. In as many as one fourth of these patients, the information provided by the bone marrow examination may establish a diagnosis of a disseminated opportunistic infection when other studies are not informative. We have also discovered a previously unreported association between thrombocytopenia and the presence of bone marrow granulomas in our patients with AIDS and suggest that thrombocytopenia may be a clue to enable the clinician to predict a positive bone marrow result more accurately. The explanation for this apparent association remains to be elucidated. PMID:2733050

    The immune deficiency (IMD) signal pathway mediates immunity against Gram-negative bacteria in Drosophila. Recent studies show that the IMD pathway also involves in antiviral innate immune responses. The functions of the pathway in crustacean immunity are largely unknown. In this paper, two IMDs (FcIMD and PcIMD), one of the key elements of the IMD pathway, were identified from Chinese white shrimp Fenneropenaeus chinensis and red swamp crayfish Procambarus clarkii. Both proteins have a death domain located at the C-terminal. FcIMD was mainly expressed in the gills and stomach and PcIMD was mainly detected in the heart, hepatopancreas, and stomach. FcIMD peaked in hemocytes at 12 h after white spot syndrome virus (WSSV) challenge and it peaked in the gills at 6 h after WSSV challenge, but it was decreased at 2 h and kept the low level to 24 h in hemocytes and no obviously change in gill after Vibrio anguillarum challenge. PcIMD first decreased in hemocytes at 2 h and peaked at 12 h in hemocytes after V. anguillarum challenge. It was also upregulated in gill after bacterial challenge, peaked at 2 h, and decreased at 6 h, and then gradually increased at 12-24 h. PcIMD has no significant change in hemocytes and gill after WSSV challenge. Western blot analysis detected FcIMD protein in all tissues, and immunocytochemical analysis localized FcIMD in the cytoplasm of hemocytes. RNA interference analysis showed that the IMD pathway was involved in regulating the expression of three kinds AMP genes, including crustins, anti-lipopolysaccharide factors and lysozymes, in shrimp and crayfish. They are Cru 1, Cru 2, ALF 1, ALF 2 and Lys 1 in crayfish, and Cru1, Cru 3, ALF 6, ALF 8, and Lys2 in shrimp. These results suggest that although IMD distribution and expression patterns have some differences, the IMD pathway may have conserved function for AMP regulation in shrimp and crayfish immunity against Gram-negative bacteria.

    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.

    Purpose Immune-deficient mice serve as critical hosts for transplantation of xenogeneic cells for in vivo analysis of various biological processes. Since investigators typically select one or two immune-deficient mouse strains as recipients, no comprehensive study has been published documenting differences in human tumor engraftment. Taking advantage of the increased metastatic potential of RhoC-expressing human (A375) melanoma cells, we evaluate 4 immune-deficient mouse strains: scid, NOD-scid, NOD-scid β2mnull, and NOD-scid IL2Rγnull as xenograft tumor recipients. Experimental design Bioluminescence, magnetic resonance imaging and histopathology was employed to monitor serial tumor growth. NK cell function was examined in each mouse strain using standard 51 Chromium release assays. Results Melanoma metastases growth is delayed and variable in scid, and NOD-scid mice. In contrast, NOD-scid β2mnull and NOD-scid IL2Rγnull mice show rapid tumor engraftment, although tumor growth is variable in NOD-scid β2mnull mice. NK cells were detected in all strains except NOD-scid IL2Rγnull, and in vitro activated scid, NOD-scid and NOD-scid β2mnull NK cells kill human melanoma lines and primary melanoma cells. Expression of human NKG2D ligands MHC class I chain-related A and B molecules renders melanoma susceptible to murine NK cell-mediated cytotoxicity and killing is inhibited by antibody blockade of murine NKG2D. Conclusions Murine NKG2D recognition of MICA/B is an important receptor-ligand interaction employed by NK cells in immune-deficient strains to limit engraftment of human tumors. The absolute NK deficiency in NOD-scid IL2Rγnull animals makes this strain an excellent recipient of melanoma and potentially other human malignancies. PMID:19447870

    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.

    Acute constriction ring syndrome (ACRS) is a rare clinical condition characterized by formation of a circumferential constriction ring around an appendage or genitalia. Cases are mostly reported in infants and young children. Early recognition and a definitive treatment are of paramount importance in order to avoid irreversible ischemia and possible auto-amputation. We describe a case of a 14-month-old child presented to casualty with a history of refusal to feed and inconsolable cry. Parents noticed a recent swelling of left third toe. On careful examination the child was found to have an acquired constriction ring secondary to a tightly wrapped hair around left third toe. An urgent surgical decompression was done by the orthopaedic team with complete resolution of symptoms. We summarized the pathophysiology of ACRS underlining the need of awareness in treating physicians. The possible medico legal implications should be kept in mind bearing a suggested link with non-accidental injury. PMID:18702819

    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.

    A defective murine leukemia virus is the causative agent of murine acquired immunodeficiency syndrome (MAIDS). We have cloned cDNAs from both virus infected and non-infected cells using the PCR methods with primers corresponding to the franking sequence of the unique p12 gag gene. Sequence analysis of these cDNA clones revealed: (i) the presence of endogenous virus related to MAIDS virus in C57BL/6 mice, (ii) B cell lineage specific expression of endogenous virus and (iii) extensive heterogeneity of MAIDS virus recovered from virus infected cells due to the recombination of the related viruses (defective pathogenic virus, ecotropic virus and endogenous virus). These findings suggest that the creation of virus variants in infected cells may play an important role in virus pathogenesis and escape from immune attack during the development of MAIDS.

    We report a patient with acquired immunodeficiency syndrome dementia complex (ADC) that presented human immunodeficiency virus infection as an initial manifestation. A 34-year-old man developed disturbance of consciousness and severe abulia over 3 months. The CD4 lymphocyte count was 7.9/microl, while human immunodeficiency virus RNA in blood amounted to 4.2 x 10(4) copies/ml. T2-weighted magnetic resonance imaging showed diffusely high signal intensity in the deep white matter of both cerebral hemispheres. On the 20th hospital day, the patient died of sepsis caused by methicillin-resistant Staphylococcus aureus. Autopsy findings in the brain included increased glial cells and multinucleated giant cells in cerebral white matter and subcortical gray matter. These features were compatible with ADC.

    We report a unique case of Turner syndrome associated with acquired von Willebrand disease (AvWD), primary biliary cirrhosis (PBC), and inflammatory bowel disease (IBD). During 7 years of close follow-up, the patient presented with multiple major episodes of upper and lower gastrointestinal bleeding caused by different pathogenic mechanisms, such as IBD, AvWD, gastric varices, and thrombocytopenia. AvWD mimicking familial vWD type III on laboratory testing was most probably triggered by autoimmune mechanism associated with PBC. Therapy of PBC with ursodeoxycholic acid (UDCA) resulted in significant decrease of liver enzymes followed by normalization of vWF and FVIII levels. Portosystemic shunt placement with ligation of gastric varices improved hypersplenism and severe thrombocytopenia and led to clinical stability for more than 24 months. The clinicopathological features of these disorders and of the recurrent bleeding episodes are discussed in the text along with a review of the literature. PMID:12116986

    A case of acquired Brown syndrome caused by surgical repair of medial orbital wall fracture is reported in the present paper. A 23-year-old man presented at the hospital with right periorbital trauma. Although the patient did not complain of any diplopia, the imaging study revealed a blow-out fracture of the medial orbital wall. Surgical repair with a calvarial bone autograft was performed at the department of plastic surgery. The patient was referred to the ophthalmologic department due to diplopia that newly developed after surgery. The prism cover test at distant fixation showed hypotropia of the right eye, which was 4 prism diopters (PD) in primary gaze, 20 PD in left gaze, while orthophoric in right gaze. Eye movement of the right eye was markedly limited on elevation in adduction with normal elevation in abduction with intorsion in the right eye present. Forced duction test of the right eye showed restricted elevation in adduction. Computerized tomography scan of the orbits showed the right superior oblique muscle was entrapped between the autografted bone fragment and posterior margin of the fracture. When repairing medial orbital wall fracture that causes Brown syndrome, surgeons should always be careful of entrapment of the superior oblique muscle if the implant is inserted without identifying the superior and posterior margin of the orbital fracture site.

    Acquired von Willebrand syndrome (AVWS) is a rare bleeding disorder with laboratory findings similar to those for congenital von Willebrand disease (VWD). Unlike VWD, AVWS usually occurs in individuals with no personal or family history of bleeding. The prevalence of AVWS in the general population is unknown because data from large prospective studies of this syndrome are not available. Although AVWS is more frequently associated with lympho-myeloproliferative and cardiovascular disorders, it can also occur in solid tumors and in immunological and other miscellaneous conditions. Among these miscellaneous conditions, hypothyroidism has been associated with AVWS type 1 with a frequency of ~2 to 5%. In the 47 cases reported in the literature, the low VWF is apparently due to a reduction in its synthesis and/or secretion. Diagnosis of AVWS is based on assays measuring the level and activity of von Willebrand factor (VWF). These tend to be low, whereas factor VIII (FVIII) coagulant activity can be normal. In patients with AVWS associated with hypothyroidism, mucocutaneous bleeding episodes are the most frequent and can be managed with local therapy and/or systemic administrations of antifibrinolytic agents and desmopressin. VWF/FVIII concentrates have been used in only a few patients. The use of thyroid hormones can reverse this abnormality. PMID:21305800

    Community physicians may play an increasing role in treating patients with acquired immunodeficiency syndrome (AIDS) because of the shift away from inpatient care. At a community hospital in New York, NY, we surveyed 230 attending physicians in a department of medicine to determine their attitudes toward the care of patients with AIDS. Factor analysis produced three clusters of attitudes termed antipathy, liability, and isolation. These factors, together with physicians' "knowledge" and background, were analyzed as predictors of treating patients with AIDS. While antipathy, isolation, and fear of acquiring AIDS were not predictors, liability scores were inversely correlated with the likelihood of treating the disease (r = -.18). Liability was influenced by patients' attitudes toward AIDS. Primary care physicians had higher liability and isolation scores than subspecialists and were more likely to see support groups, guaranteed funding, and education as incentives to treat patients with AIDS. Further study is needed to target measures that support primary care physicians in their care of patients with this disease. PMID:2297299

    Acquired von Willebrand syndrome (AvWS) is a rare bleeding disorder with clinical and laboratory features closely resembling hereditary von Willebrand disease (vWD), arising in previously haemostatically normal individuals. We present a retrospective review of 10 cases with AvWS diagnosed over 17 years. The severity of the bleeding tendency varied from mild to severe forms. Multimers electrophoresis showed that 8/10 patients had a normal pattern similar to type 1 vWD, 1/10 had a type 2A vWD pattern (with absence of high and intermediate molecular weight multimers) and 1/10 had a type 3 vWD pattern. An inhibitor screen was performed in 6/10 patients and autoantibodies against von Willebrand factor were found in only two cases. The underlying cause/associated conditions were identified in 8/10 patients. Treatment of the bleeding diathesis was successfully achieved with desmopressin or clotting factor concentrates. Resolution of underlying hypothyroidism (in two cases) and multiple myeloma (in one case) led to normalization of the coagulation parameters. The report on this cohort of 10 patients with AvWS illustrates the complexity of AvWS and its multifactorial aetiology. A brief review of the recent literature on AvWS is also presented, with emphasis on the current opinions in pathogenesis and treatment. Acquired von Willebrand syndrome (AvWS) is an acquired bleeding disorder, characterized by a phenotype similar to the inherited von Willebrand disease (vWD), with a prolonged bleeding time and low plasma levels of factor VIII - von Willebrand factor (vWF) measurements. It occurs in patients with no family history of vWD, who present with recent onset of bleeding symptoms. AvWS appears to be associated mainly with lymphoproliferative disorders, immunological conditions and neoplasia. AvWS is a rare condition and it is difficult to conduct prospective studies, therefore it is important to document the experience with such cases. The aim of this paper is first, to

    Hematopoietic cell transplantation (HCT) is a curative therapeutic option for severe combined immunodeficiency (SCID), a group of diseases which otherwise carry life expectancies that are of limited duration and quality. Survival following HCT for SCID has improved from approximately 23 to 91 % over the last 40 years. Success with SCID prompted efforts to apply HCT to the therapeutic challenge of well over 20 molecularly defined primary immune deficiency diseases (PID). Such success is due to both early recognition of PIDs and advances in the field of transplantation. Such advances include high-resolution HLA DNA donor-recipient matching, expansion of donor sources, better tolerated conditioning, new antibiotics, and wider availability. International collaborative efforts have provided patients and caregivers information that permit better treatment decisions now, and direct clinicians and investigators to ensure progress in the future. Pioneers in screening for SCID have taken steps to correct the fundamental challenge to successful treatment, which is the rapid discovery and characterization of cases and offering the transplant option to an affected child early in life; blood spot testing for T and B cell receptor quantification is now available to a growing fraction of newborns. Organizations including the Primary Immune Deficiency Treatment Consortium in the USA, The European Society for Primary Immunodeficiency, the European Group for Blood and Marrow Transplantation, the Pediatric Blood and Marrow Transplant Consortium, the United States Immunodeficiency Network, the Immune Deficiency Foundation, and the Jeffrey Modell Foundation are contributing mightily to increase awareness and standardize optimal utilization to the benefit of patients. This review will update the allergist-immunologist concerning disease presentations, indications for transplantation, methodologies, conditioning regimens, and clinical outcomes for patients with PID for which timely HCT is

    One of the complications of the use of antiretroviral therapy (ART), immune reconstitution inflammatory syndrome (IRIS), is particularly problematic in the management of cryptococcal meningitis. We present the case of a 35-year-old male with acquired immune deficiency syndrome diagnosed with extensive central nervous system (CNS) cryptococcal disease, including meningitis and multiple intracranial cysts, diagnosed eight weeks after the initiation of ART. The patient experienced a relapsing and remitting clinical course despite repeated courses of potent antifungal therapy and aggressive management of raised intracranial pressure. This review highlights therapeutic dilemmas and strategies in the management of CNS cryptococcosis complicated with IRIS and highlights gaps in available treatment guidelines. PMID:25568756

    Patients with common variable immunodeficiency (CVID) have a higher incidence of autoimmune disease, which may mark the disease onset; however, anemia secondary to pure red cell aplasia is an uncommon presenting feature. Here, we describe a case of CVID-like humoral immune deficiency in a child who initially presented with red cell aplasia and ultimately developed progressive bone marrow failure. Although bone marrow transplantation (BMT) has been associated with high mortality in CVID, our patient was successfully treated with a matched sibling BMT and engrafted with >98% donor chimerism and the development of normal antibody titers to diphtheria and tetanus toxoids.

    Seven patients with acquired immunodeficiency syndrome (AIDS) and Pneumocystis carinii pneumonia were studied to define the pathophysiology of their respiratory failure. The patients had fever, cough, dyspnea, hypoxemia, and diffuse infiltrates on chest x-ray. Biopsies revealed a spectrum of alveolar filling, interstitial edema and infiltration, and fibrosis. The patients were studied on mechanical ventilation to assess the effect of positive end-expiratory pressure (PEEP) and supplemental oxygen on shunt fraction. Mean anatomic shunt (measured on 100% oxygen) was 34 +/- 8%, which increased significantly (p less than .001) to 43 +/- 9% when the FIO2 was decreased to 40% to 60% (physiologic shunt), indicating ventilation/perfusion (V/Q) imbalance or impaired diffusion. Increasing PEEP by 9 +/- 2 cm H2O reduced the anatomic shunt to 30 +/- 7% (p less than .01) and the physiologic shunt to 37 +/- 7% (p less than .02). There was a similar decrease in anatomic and physiologic shunts in five studies, a greater decrease in physiologic shunt in four, and a greater decrease in anatomic shunt in two. Evidence of alveolar recruitment with PEEP, measured by an increase in static thoracic compliance, was found in only one study. There was no correlation between the effect of PEEP on compliance and its effect on shunt. The data suggest that in patients with AIDS and P. carinii pneumonia, PEEP can decrease shunt by reducing the anatomic shunt, improving V/Q imbalance, and converting areas of anatomic shunt to areas of low V/Q. P. carinii pneumonia in patients with AIDS can produce a clinical and pathophysiologic pattern similar to that described in the adult respiratory distress syndrome. PMID:3516574

    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

    Humoral immune deficiencies have been associated with noninfectious disease complications including autoimmune cytopenias and pulmonary disease. Herein we present a patient who underwent splenectomy for autoimmune cytopenias and subsequently was diagnosed with humoral immune deficiency in the context of recurrent infections. Immunoglobulin analysis prior to initiation of intravenous immunoglobulin (IVIG) therapy was notable for low age-matched serum levels of IgA (11 mg/dL), IgG2 (14 mg/L), and IgG4 (5 mg/L) with a preserved total level of IgG. Flow cytometry was remarkable for B cell maturation arrest at the IgM+/IgD+ stage. Selective screening for known primary immune deficiency-causing genetic defects was negative. The disease course was uniquely complicated by the development of pulmonary arteriovenous malformations (AVMs), ultimately requiring bilateral lung transplantation in 2012. This is a patient with humoral immune deficiency that became apparent only after splenectomy, which argues for routine immunologic evaluation prior to vaccination and splenectomy. Lung transplantation is a rare therapeutic endpoint and to our knowledge has never before been described in a patient with humoral immune deficiency for the indication of pulmonary AVMs. PMID:25379312

    Common variable immune deficiency (CVID) is the most common symptomatic primary immune deficiency, affecting ∼1 in 25,000 persons. These patients suffer from impaired antibody responses, autoimmunity, and susceptibility to lymphoid cancers. To explore the cellular basis for these clinical phenotypes, we conducted high-throughput DNA sequencing of immunoglobulin heavy chain gene rearrangements from 93 CVID patients and 105 control subjects and sorted naïve and memory B cells from 13 of the CVID patients and 10 of the control subjects. CVID patients showed abnormal VDJ rearrangement and abnormal formation of complementarity determining region 3 (CDR3). We observed decreased selection against antibodies with long CDR3 regions in memory repertoires and decreased V gene replacement, offering possible mechanisms for increased patient autoreactivity. Our data indicate that patient immunodeficiency might derive both from decreased diversity of the naïve B cell pool and decreased somatic hypermutation in memory repertoires. CVID patients also exhibited abnormal clonal expansion of unmutated B cells relative to controls. Although impaired B cell germinal center activation is commonly viewed as causative in CVID, these data indicate that CVID B cells diverge from controls as early as the pro-B cell stage and suggest possible explanations for the increased incidence of autoimmunity, immunodeficiency, and lymphoma CVID patients.

    More than 20 North American academic centers account for the majority of hematopoietic stem cell transplantation (HCT) procedures for primary immunodeficiency diseases (PIDs), with smaller numbers performed at additional sites. Given the importance of a timely diagnosis of these rare diseases and the diversity of practice sites, there is a need for guidance as to best practices in management of patients with PIDs before, during, and in follow-up for definitive treatment. In this conference report of immune deficiency experts and HCT physicians who care for patients with PIDs, we present expert guidance for (1) PID diagnoses that are indications for HCT, including severe combined immunodeficiency disease (SCID), combined immunodeficiency disease, and other non-SCID diseases; (2) the critical importance of a high degree of suspicion of the primary care physician and timeliness of diagnosis for PIDs; (3) the need for rapid referral to an immune deficiency expert, center with experience in HCT, or both for patients with PIDs; (4) medical management of a child with suspicion of SCID/combined immunodeficiency disease while confirming the diagnosis, including infectious disease management and workup; (5) the posttransplantation follow-up visit schedule; (6) antimicrobial prophylaxis after transplantation, including gamma globulin administration; and (7) important indications for return to the transplantation center after discharge. Finally, we discuss the role of high-quality databases in treatment of PIDs and HCTas an element of the infrastructure that will be needed for productive multicenter clinical trials in these rare diseases.

    Histoplasmosis occurs in approximately 5% of acquired immunodeficiency syndrome (AIDS) patients in endemic areas and often evolves to a disseminated picture if diagnosis is delayed and/or CD4 count falls below 150 cells x mm(3) without high active antiretroviral therapy (HAART). This report presents clinical features of patients with histoplasmosis admitted from 1992 to 2005. Of the 57 individuals, 45 (79%) were male, aged 20-40 years; 30 (52.6%) presented histoplasmosis together with HIV diagnosis and 35 (61.4%) referred illness course up to 4 weeks. Fever, hepatomegaly and/or splenomegaly, dyspnea and skin lesions were noticed in 50 (87.7%), 38 (66.7%), 30 (52.6%) and 25 (43.9%) patients respectively. High levels of lactic acid dehydrogenase, X-ray lung interstitial pattern, pancytopenia and CD4 count <100 cells x mm(3) were observed in 48 (84.2%), 35 (66%), 34 (59.6%) and 33 (94%) patients respectively. Mycological diagnosis was performed by one or more methods in all patients. Thirty nine (68.4%) received amphotericin B and/or itraconazole. A cure rate was observed in 76.9% and nine (23.1%) died early during therapy. Otherwise death occurred in 18 (31.6%) before diagnosis was completed. Despite free HAART disposal in public Brazilian health services, histoplasmosis still occurs as the first AIDS baseline condition in patients without antiretroviral therapy, many of whom are not receiving any medical care for HIV infection.

    22 homosexual or narcotic addict patients at risk for acquired immunodeficiency syndrome (AIDS) or with AIDS, were studied for the presence of antiimmunoglobulin antibodies and circulating immune complexes (20 were thrombocytopenic, 6 had AIDS). Circulating immune complex levels were 10-fold higher than levels in normal subjects. IgG anti-F(ab')2 antibodies were noted in homosexual as well as narcotic addict patients. Of 16 homosexual patients, 7 had IgG anti-F(ab')2 antibody of moderate to marked titer with broad reactivity against autologous, homologous, and control F(ab')2 fragments. Three others demonstrated limited reactivity against one or two F(ab')2 fragments. The remaining six patients were negative. Six of six narcotic addict patients had IgG anti-F(ab')2 antibody, five with limited reactivity, one with broad reactivity. In contrast, neither elevated circulating immune complexes nor anti-F(ab')2 antibodies were detectable in six autoimmune thrombocytopenic patients. Anti-F(ab')2 antibody could be affinity purified from serum or circulating immune complexes. Anti-F(ab')2 reactivity correlated with circulating immune complex levels, r = 0.83, P less than 0.01.

    Fourteen patients with acquired immunodeficiency syndrome (AIDS) or suspected AIDS underwent percutaneous needle lung aspiration (PNLA) for evaluation of 16 occurrences of acute pneumonitis. A 22-gauge spinal needle was passed 2 to 3 times in the area of greatest radiographic involvement under fluoroscopic guidance. The specimen was immediately placed on microscope slides for Gomori's methenamine silver and Papanicolaou staining. The needle was then flushed with sterile water for bacterial, Legionella, viral, mycobacterial, and fungal cultures, and for Legionella immunofluorescent staining. Diagnostic information was provided by 14 of the 16 procedures. Of 11 patients ultimately found to have P. carinii pneumonitis, PNLA specimens were diagnostic in 10 (91%). Infectious agents other than P. carinii also were identified by PNLA, including cytomegalovirus (4 cases), M. avium-intracellulare (1 case), and pyogenic bacteria (3 cases). Complications of PNLA were: pneumothorax in 7 cases (44%), 3 (19%) of which required chest tube evacuation; and minor hemoptysis (less than 50 ml) in 2. The PNLA can be a useful diagnostic procedure in the patient with AIDS and pneumonitis. It has the advantages of being less costly and time-consuming than fiberoptic bronchoscopy. It is, however, frequently complicated by pneumothorax, making it an inappropriate approach for patients with significant respiratory compromise. PMID:3872089

    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. PMID:26751889

    The acquired hyperostosis syndrome (AHS) is a chronic inflammatory disorder of bone of unknown etiology. It is accompanied by circumscribed hyperostosis which can be associated with ossifying lesions at sites of tendinous and ligamentary insertions and erosive or non-erosive arthritis. The predominant location of lesions is the sternocostoclavicular region (approximately 80% of patients), less frequent are involvement of the spine, pelvis, and appendicular skeleton. In 20%-60% of cases AHS is associated with palmoplantar pustulosis, psoriasis, or severe acne (acne fulminans or conglobata). The X-ray appearance of AHS is a more or less homogeneous increase in density with blurred margins, which on scintiscan with labeled phosphate compounds is associated with intense accretion of tracer. These features are associated with a variable increase in the acute phase reactants and a conspicuously low increase, if any, in serum alkaline phosphatase. The therapeutic modalities which have been used so far are entirely symptomatic. Long-lasting improvement has been reported following percutaneous anti-inflammatory radiation therapy. PMID:8136615

    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.

    Purpose To describe an unusual case of rapidly progressive outer retinal necrosis (PORN) with vitreous hemorrhage in a 41-year-old woman with acquired immunodeficiency syndrome (AIDS), who had retinitis developed from what was probably varicellar-zoster virus combined with cytomegalovirus (CMV) and herpes simplex type 1,2, as proven by the polymerase chain reaction restriction fragment length polymorphism method (PCR-RFLP). Methods This study is a case report detailing clinical follow-up and an aqueous humor test by PCR-RFLP. Results The deep, white retinal lesions coalesced and progressively expanded in a circumferential manner, with sparing of the perivascular retina. However, retinal and vitreous hemorrhages, unusual findings for PORN, could be noted around the optic nerve. Varicellar-zoster virus (VZV), cytomegalovirus (CMV), and herpes simplex types 1,2 (HSV-1,2) were detected in the aqueous humor by PCR. Conclusions PORN has been described as a variant of necrotizing herpetic retinopathy, occurring particularly in patients with AIDS. Although the etiologic agent has been reported to be VZV, concurrent or combined etiologic agents can include HSV-1, HSV-2, and CMV in AIDS patients. Therefore, combined antiviral therapy with acyclovir and ganciclovir could be more reasonable as an initial therapy. PMID:17460434

    Patients with bacteremia, bacterial endocarditis, or acquired immunodeficiency syndrome (AIDS) were prospectively studied using monoclonal antibody reagents to assess alterations in T-lymphocyte subpopulations. Patients with endocarditis had significantly higher ratios of T-helper (OKT4+) to T-suppressor-cytotoxic (OKT8+) cells than did patients with bacteremia alone. Staphylococcus aureus endocarditis patients had a mean ratio of 8.49 (range 4.73-22.36) while S aureus bacteremia had a mean ratio of 2.75 (range 2.15 to 3.21). Similar results were found with Staphylococcus epidermidis endocarditis (mean 1.62) and bacteremia (mean 1.23). Klebsiella pneumoniae endocarditis (5.10) and sepsis (4.32), and E coli bacteremia (2.15). Nine male patients with AIDS had markedly depressed ratios (mean 0.25, range 0.04 to 0.67) while eight male homosexuals with unexplained lymphadenopathy ("pre-AIDS") had normal or increased ratios. Bacteremic infections are associated with an increased OKT4+/OKT8+ ratio with the degree of increase dependent upon virulence, location, and duration of infection. The immunomodulating effects of infection are manifested in changes in T-cell subsets, and these measurements can be useful in clinical management. PMID:6094086

    Acquired von Willebrand syndrome (AVWS) is a rare bleeding disorder that may cause life-threatening hemorrhages in patients with plasma cell dyscrasias (PCDs). Early diagnosis and treatment require a thorough understanding of its underlying pathophysiology. Two patients with IgG MGUS presented with dramatically decreased plasma von Willebrand factor (VWF) and a severe type-1 pattern on multimer analysis. A prompt response to intravenous immunoglobulins (IVIG), but not to VWF/FVIII, was consistent with accelerated immunologic clearance of plasma VWF. Another IgG MGUS patient showed a type-2 pattern and a less pronounced response to IVIG, suggesting that additional mechanism(s) contributed to AVWS evolution. In a patient with Waldenström's macroglobulinemia and severe depletion of plasma VWF, multimer analysis indicated association of the IgM paraprotein with VWF before, but not after plasmapheresis, resulting in destruction of the agarose gel and a characteristically distorted band structure of VWF multimers. A type-2 pattern with highly abnormal VWF triplets and laboratory evidence of excessive fibrinolytic activity suggested that plasmin-mediated VWF degradation contributed to AVWS in a patient with multiple myeloma (MM) and AL amyloidosis. Finally, in a patient with IgG MM, maximally prolonged PFA-100® closure times and a specific defect in ristocetin-induced platelet agglutination, both of which resolved after remission induction, indicated interference of the paraprotein with VWF binding to platelet GPIb. Importantly, in none of the six patients, circulating autoantibodies to VWF were detected by a specific in-house ELISA. In summary, when evaluating PCD patients with severe bleeding symptoms, AVWS due to various pathogenic mechanisms should be considered. PMID:27040683

    BACKGROUND AND AIMS: The optimum diagnostic investigation for patients with acquired immunodeficiency syndrome (AIDS) and diarrhoea is not known. Often no pathogen is detected and it is unclear whether this is because pathogens are absent in some patients or the investigations used fail to detect them. The hypothesis that AIDS related diarrhoea is usually due to an infection, which can be identified by a simple diagnostic strategy based on the results of intensive investigation of a cohort of such patients, was investigated. METHODS: 155 patients with AIDS and chronic diarrhoea underwent contemporaneous examination of stools, duodenal, jejunal, and rectal biopsy specimens and duodenal aspirate for bacterial, protozoal, and viral pathogens. A decision tree analysis was used to determine the best sequential diagnostic strategy for clinicians. RESULTS: 128 of 155 patients investigated (83%) had at least one potential pathogen. The presenting clinical features could not predict the presence or site of the pathogens. Stool analysis identified the most pathogens (93 of 199, 47%). Rectal biopsy was essential for the diagnosis of cytomegalovirus and adenovirus. Duodenal biopsy was as helpful as jejunal biopsy and detected some treatable pathogens missed by other methods. Electron microscopy, impression smears, and duodenal aspirate yielded little extra information. If gut biopsy was reserved for patients without a stool pathogen, some treatable pathogens would have been missed. CONCLUSION: Most patients with AIDS and chronic diarrhoea have at least one gut pathogen, which can be identified by stool analysis and light microscopic examination of duodenal and rectal biopsies. Some pathogens will be missed unless all these investigations are done on all such patients. PMID:9038664

    We report a case of acquired von Willebrand syndrome (AVWS) in a 20-year-old-woman with systemic lupus erythematosus, in whom severe bleeding complications followed kidney biopsy. Coagulation studies demonstrated undetectable levels of ristocetin-induced platelet aggregation (RIPA), von Willebrand factor antigen (VWF:Ag) and VWF ristocetin cofactor activity (VWF:RCo), associated with significantly prolonged bleeding time; unlike type 3 von Willebrand disease (VWD), platelet VWF was reduced but not undetectable. The plasma VWF multimer pattern was characterized by the presence of only two bands, one of low molecular weight (MW) running as the protomer of plasma VWF in normals, the other of abnormally high MW without detectable intermediate multimers; this pattern resembles that of VWF present in endothelial cells. A search for an anti-VWF antibody demonstrated the presence of an inhibitor at high titre. This anti-VWF antibody did not interfere in the interaction of VWF with platelet glycoprotein (GP) Ib through the A1 domain, and did not react with the A2 domain of VWF; instead, it seemed to modify the relative representation of high and low MW VWF multimers released by normal human umbilical vein endothelial cells (HUVEC). After Azathioprine and corticosteroid treatment, the anti-VWF antibody disappeared and the patient's haemostatic profile normalized, except for the platelet VWF content which still remained decreased. We suggest that the anti-VWF antibody present in the AVWS described compromised both circulating VWF levels and their multimeric organization, inducing the maintenance of the multimer structure that VWF normally has before or in the early phase after secretion from endothelial cells.

    In this report, we provide evidence of an acquired von Willebrand syndrome (AVWS) with a type 2B phenotype rather than the expected type 1 or 2A. The patient was referred prior to surgical removal of a fibrous mass within the maxillary sinus. His first bleeding 7 years earlier following a retinal tear had been complicated by monocular blindness. Several mucocutanous bleedings followed. Hematological investigations revealed von Willebrand factor (VWF):Ag 91 IU/ml, factor VIII 86 IU/ml, VWF:RCo 34 IU/ml and profound thrombocytopenia with platelet clumping. VWF multimer analysis showed a loss of high-molecular-weight multimers and his plasma aggregated normal platelets under low ristocetin concentration, consistent with type 2B von Willebrand disease (VWD). Sequencing of VWF exon 28 and of the platelet GP1BA gene to investigate the possibility of platelet-type VWD failed to reveal mutations. Serum protein electrophoresis showed a monoclonal IgG protein and led to the diagnosis of monoclonal gammopathy of unknown significance (MGUS), raising suspicion of an AVWS. Over 2 years, he experienced severe gingival bleedings and traumatic intracerebral hemorrhage. Following debridement of the sinus mass, the patient required 20 units of packed red blood cells, despite high-dose Humate-P, continuous Amicar and twice-daily platelet transfusions. Bleeding finally ceased following infusion of activated factor VIIa. A history of prior uncomplicated vasectomy and tendon laceration, no family history of bleeding, the inability to identify a causative mutation in either exon 28 VWF or platelet GP1BA and the MGUS led to diagnosis of AVWS with a type 2B phenotype. This case highlights the difficulties in assigning a diagnosis and the management of bleeding in a patient with an atypical presentation of AVWS. PMID:24296552

    Lymphocytic interstitial pneumonitis (LIP) is currently recognized as a frequent pediatric manifestation of the acquired immunodeficiency syndrome (AIDS). We report the gallium scan findings in a 3-yr-old girl with this disorder and review its clinical, radiologic, and pathologic features. LIP must be a prime consideration in the differential diagnosis of diffuse pulmonary gallium uptake in pediatric AIDS patients. Further experience will afford greater perspective on the diagnostic role that nuclear medicine will ultimately play in this disease. 49 references.

    Sub-Saharan Africa is considered home to more than 60% of all human immunodeficiency virus (HIV) infected cases, with an estimated adult prevalence of 8.0%. It is stated that this region has contributed more than 90% of childhood deaths related to HIV infection and about 93% of childhood acquired immunodeficiency syndrome (AIDS)-related deaths. Although no country in Africa is spared of the infection, the bulk is seen in East and South Africa, with the highest recorded rates of 20% to 50% in Zimbabwe. On the other hand, West Africa is less affected, while countries in Central Africa have relatively stable infection rates. Although infections, especially tuberculosis, have emerged as the most important HIV/AIDS-associated killers in recent times, AIDS-associated malignancies are increasingly identified in the late stages. As a result of incomplete data from African countries, it is unclear whether the epidemiology and risks of these cancers are the same as observed in the developed countries. Since the advent of AIDS, epidemic Kaposi's sarcoma (KS) has become more common in both sexes in Africa, with a dramatic lowering of the male to female ratio from 19:1 to 1.7:1, especially in East Africa. Although there has been a rising trend of AIDS-associated non-Hodgkin's lymphoma (NHL) worldwide, there is an apparently lower risk in Africa compared with that in the developing world. At present, there is no strong evidence linking increased incidence of invasive cervical cancer to the HIV epidemic; however, some studies have demonstrated an association between HIV and the increased prevalence of human papilloma virus (HPV) and cervical intraepithelial neoplasia (CIN). On the other hand, HIV infection is now established as a risk factor for the development of squamous cell neoplasia of the conjunctiva based on studies from Rwanda, Malawi, and Uganda. Despite the problems and limitations of information from sub-Saharan Africa, interesting trends of HIV/AIDS-related cancers

    Although human immunodeficiency virus (HIV) disease is increasing rapidly among women, no prior studies have investigated gender-based therapeutic strategies for the treatment of acquired immunodeficiency syndrome (AIDS) and its complications in this population. Markedly decreased serum androgen levels have been demonstrated in women with AIDS and may be a contributing factor to the wasting syndrome in this population. To assess the effects of androgen replacement therapy in women with AIDS wasting, we conducted a randomized, placebo-controlled, pilot study of transdermal testosterone administration. The primary aim of the study was to determine efficacy in terms of the change in serum testosterone levels, safety parameters and tolerability. A secondary aim of the study was to investigate testosterone effects on weight, body composition, quality of life, and functional indexes. Fifty-three ambulatory women with the AIDS wasting syndrome defined as weight less than 90% of ideal body weight or weight loss of more than 10% of the preillness maximum, free of new opportunistic infection within 6 weeks of study initiation, and with screening serum levels of free testosterone less than the mean of the normal reference range (< 3 pg/mL) were enrolled in the study. Subjects were age 37 +/- 1 yr old (mean +/- SEM), weighed 92 +/- 2% of ideal body weight, and had lost 17 +/- 1% of their maximum weight. CD4 count was 324 +/- 36 cells/mm3, and viral burden was 102,382 +/- 28,580 copies. Subjects were randomized into three treatment groups, in which two placebo patches (PP), one active/one placebo patch (AP group), or two active patches (AA group) were applied twice weekly to the abdomen for 12 weeks. The expected nominal delivery rates of testosterone were 150 and 300 microg/day, respectively, for the AP and AA groups. Forty-five subjects completed the study (PP group, n = 13; AP group, n = 14; AA group, n = 18). Two additional subjects from the PP group and two from the AP

    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.

    The case of a 20-year old female, who had been followed because of von Willebrand disease (vWD) was presented in this paper . She had a past history of menorrhagia and bleeding after dental procedures and the activity of von Willebrand factor (vWF) was decreased. Because of suggestive clinical features, the workup for hypothyroidism was performed and the patient was found to have severe hypothyroidism due to Hashimoto thyroiditis. After the institution of replacement therapy with levothyroxine, von Willebrand factor activity returned to normal range and symptoms of von Willebrand disease disappeared. Based on these findings, the diagnosis of acquired von Willebrand syndrome (AvWS) due to hypothyroidism was made. The development of myasthenia led to the final diagnosis of autoimmune polyglandular syndrome type 3 (APS) with myasthenia gravis and vitiligo. PMID:18335399

    The use of high dose chemotherapy followed by autologous hematopoietic stem cell transplantation for remission consolidation after initial induction represents standard of care for patients with multiple myeloma. Patients with myeloma and Acquired von Willebrand Syndrome (AVWS) undergoing autologous stem cell transplant (ASCT) are at significant risk of bleeding due to the profound thrombocytopenia, low Factor VIII levels, fever, and toxicities associated with the preparative regimen. We report a patient with AVWS associated with multiple myeloma who underwent autologous stem cell transplants as consolidation after initial induction and again at relapse. He was successfully treated with high dose intravenous immunoglobulin (IVIG) prior to each transplant with rapid resolution of AVWS. PMID:25922770

    The cumulative number of cases of acquired immunodeficiency syndrome (AIDS) in the United States has grown as the cube of time rather than exponentially. We explain this by interactions involving partner choice and sexual frequency in a risk-behavior model with biased mixing. This leads to a saturation wave of infection moving from high- to low-risk groups. If this description is correct, then the decreasing growth rate of AIDS cases is not due to behavior changes; rather it is due to the intrinsic epidemiology of the disease. PMID:2543987

    A syndrome of acquired immunodeficiency within a group of outdoor-housed rhesus macaques (Macaca mulatta) with unusually high mortality has been identified at the California Primate Research Center. The cause of death for most of the affected animals included septicemia and/or chronic diarrhea with wasting, often complicated by other problems. In many cases, multiple or unusual infectious agents were isolated or recognized, including cytomegalovirus, Cryptosporidium spp., and Candida albicans. Septicemias due to usually innocuous agents such as Staphylococcus epidermidis and Alcaligenes faecalis were seen. Two animals developed cutaneous fibrosarcomas. Affected animals had generalized lymphadenopathy and splenomegaly, with depletion of T-cell populations, initially follicular hyperplasia followed by depletion, and absence of plasma cells. This spontaneous disease syndrome in nonhuman primates has similarities to acquired immune deficiency syndrome (AIDS) in humans, providing an animal model for the study of the complex factors modulating the immune system.

    A 6-year-old spayed female Jack Russell Terrier presented with a 1-month history of lethargy, anorexia, vomiting and weight loss. The dog was fed beef and chicken jerky treats daily in addition to a commercial diet. Laboratory tests revealed azotemia, hypokalemia, hyperchloremia, metabolic acidosis and glucosuria with normoglycemia. Urine amino acid analysis showed significant amino acid loss into the urine. Thus, Fanconi syndrome was diagnosed, and based on the case history and extensive diagnostic testing, excessive consumption of jerky treats was strongly suspected as the cause. Glucosuria resolved 7 days after the withdrawal of jerky treats and fluid therapy. Aminoaciduria was substantially, but not completely, improved 3 months after diagnosis. Mild azotemia remained, suggesting chronic renal disease. To the best of our knowledge, this is the first reported case of Fanconi syndrome following the consumption of jerky treats in Japan.

    Primary immune deficiency disorders (PIDs) are rare conditions for which effective treatment is available. It is critical these patients are identified at an early stage to prevent unnecessary morbidity and mortality. Treatment of these disorders is expensive and expert evaluation and ongoing management by a clinical immunologist is essential. Until recently there has been a major shortage of clinical immunologists in New Zealand. While the numbers of trained immunologists have increased in recent years, most are located in Auckland. The majority of symptomatic PID patients require life-long immunoglobulin replacement. Currently there is a shortage of subcutaneous and intravenous immunoglobulin (SCIG/IVIG) in New Zealand. A recent audit by the New Zealand Blood Service (NZBS) showed that compliance with indications for SCIG/IVIG treatment was poor in District Health Boards (DHBs) without an immunology service. The NZBS audit has shown that approximately 20% of annual prescriptions for SCIG/IVIG, costing $6M, do not comply with UK or Australian guidelines. Inappropriate use may have contributed to the present shortage of SCIG/IVIG necessitating importation of the product. This is likely to have resulted in a major unnecessary financial burden to each DHB. Here we present the case for a national service responsible for the tertiary care of PID patients and oversight for immunoglobulin use for primary and non-haematological secondary immunodeficiencies. We propose that other PIDs, including hereditary angioedema, are integrated into a national PID service. Ancillary services, including the customised genetic testing service, and research are also an essential component of an integrated national PID service and are described in this review. As we show here, a hub-and-spoke model for a national service for PIDs would result in major cost savings, as well as improved patient care. It would also allow seamless transition from paediatric to adult services. PMID:27355232

    About half of all subjects with common variable immune deficiency (CVID) are afflicted with inflammatory complications including hematologic autoimmunity, granulomatous infiltrations, interstitial lung disease, lymphoid hyperplasia and/or gastrointestinal inflammatory disease. The pathogenesis of these conditions is poorly understood but singly and in aggregate, these lead to significantly increased (11 fold) morbidity and mortality, not experienced by CVID subjects without these complications. To explore the dysregulated networks in these subjects, we applied whole blood transcriptional profiling to 91 CVID subjects, 47 with inflammatory conditions and 44 without, in comparison to subjects with XLA and healthy controls. As compared to other CVID subjects, males with XLA or healthy controls, the signature of CVID subjects with inflammatory complications was distinguished by a marked up-regulation of IFN responsive genes. Chronic up-regulation of IFN pathways is known to occur in autoimmune disease due to activation of TLRs and other still unclarified cytoplasmic sensors. As subjects with inflammatory complications were also more likely to be lymphopenic, have reduced B cell numbers, and a greater reduction of B, T and plasma cell networks, we suggest that more impaired adaptive immunity in these subjects may lead to chronic activation of innate IFN pathways in response to environmental antigens. The unbiased use of whole blood transcriptome analysis may provides a tool for distinguishing CVID subjects who are at risk for increased morbidity and earlier mortality. As more effective therapeutic options are developed, whole blood transcriptome analyses could also provide an efficient means of monitoring the effects of treatment of the inflammatory phenotype.

    Common variable immune deficiency (CVID) is the most frequent symptomatic primary immune deficiency in adults. The standard of care is intravenous immunoglobulin (IVIG) or subcutaneous immunoglobulin (scIG) therapy. The cause of CVID is currently unknown, and there is no universally accepted definition of CVID. This creates problems in determining which patients will benefit from IVIG/scIG treatment. In this paper, we review the difficulties with the commonly used European Society of Immune Deficiencies (ESID) and the Pan American Group for Immune Deficiency (PAGID) definition of CVID. We propose new criteria for the diagnosis of CVID, which are based on recent scientific discoveries. Improved diagnostic precision will assist with treatment decisions including IVIG/scIG replacement. We suggest that asymptomatic patients with mild hypogammaglobulinaemia are termed hypogammaglobulinaemia of uncertain significance (HGUS). These patients require long-term follow-up, as some will evolve into CVID. PMID:23859429

    The prevalence of lymphoma in primary immunodeficiency cases and autoimmune diseases, as well as on a background of immunodeficiency following organ transplants, is increasing. The lymphoma treatment success rate is known to be a low prognosis. Our study aimed to emphasize the low survival rates in immunodeficient vs. immunocompetent lymphoma patients and also to investigate the effect of rituximab in patients with ataxia telangiectasia and other immunodeficiencies. We summarized the clinical characteristics and treatment results of 17 cases with primary immunodeficiency that developed non-Hodgkin lymphoma (NHL) and Hodgkin lymphoma (HL) retrospectively. Seven patients were diagnosed with ataxia-telangiectasia, two with common variable immunodeficiency, two with selective IgA deficiency, one with X-related lymphoproliferative syndrome, one with Wiskott-Aldrich syndrome, one with Epstein-Barr virus-related lymphoproliferative syndrome, one with interleukin-2-inducible T-cell kinase (ITK) deficiency, and one with lymphoma developing after autoimmune lymphoproliferative syndrome (ALPS). One patient underwent a renal transplant. Of the nine males and eight females (aged 3-12 years, median = 7) that developed lymphoma, seven were diagnosed with HL and ten with NHL (seven B-cell, three T-cell). The NHL patients were started on the Berlin-Frankfurt-Münster, POG9317, LMB-96, or R-CHOP treatment protocols with reduced chemotherapy dosages. HL cases were started on the doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) and/or cyclophosphamide, vincristine, procarbazine, and prednisone (COPP) protocol, also with modified dosages. Importantly, all seven cases of HL are alive and in remission, while six of the ten NHL patients have died. Primary immunodeficiency is a strong predisposing factor for developing lymphoma. Low treatment success rates relative to other lymphomas and difficulties encountered during treatment indicate that new treatment agents are needed

    Introduction: Ondine’s Curse is a catastrophic but rare condition in adults. It is referred to as a congenital or acquired condition, in which the patient cannot breathe automatically while asleep. Acquired causes of this disease can be any cause affecting the ventrolateral part of the medulla, which is considered to be the breathing center in humans.  Case Report: A 51-year-old woman, with ataxia and the symptoms and signs of rising Intra-Cranial Pressure, who underwent ventriculoperitoneal shunting and removal of tumour, developed episodic apnea during sleep after surgery and hypercapnia when awake. In her post-operative CT scan, some fine spots of hypodensity in the left lateral part of the medulla were observed. She was managed pharmacologically and underwent tracheotomy. After 50 days, she was discharged from the hospital when she was able to breathe normally. Conclusion: Having experience with this condition after resection of a fourth ventricle tumor, it was found that Ondine’s Curse can be considered as one of the complications of posterior fossa surgery and is curable by proper management.

    We analyzed cases of disseminated nontuberculous mycobacterial infection (DNTM) in patients with AIDS reported to the Centers for Disease Control. Between 1981 and 1987, 2,269 cases were reported. In 96% of cases, infection was caused by M. avium complex (MAC). The number of cases has risen steadily since 1981, but the rate as a percentage of AIDS cases has remained stable at 5.5%. DNTM was seen less frequently in AIDS cases with Kaposi's sarcoma than in other AIDS cases (p less than 0.01). Rates of DNTM were lower in Hispanics and declined with age but were not significantly different by patient sex or means of acquiring HIV infection. Rates of disseminated MAC varied by geographic region from 3.9% to 7.8% (p less than 0.0001). As assessed by helper/suppressor T-cell ratios, AIDS patients with DNTM were not more immunologically impaired than those with other opportunistic infections. Life table analysis revealed that AIDS patients with DNTM survived a shorter time (median, 7.4 months) than did other AIDS patients (median, 13.3 months; p less than 0.0001). We conclude that DNTM is acquired by unpreventable environmental exposures. Because DNTM adversely affects survival of AIDS patients, effective therapeutic agents must be vigorously sought.

    A 91-year-old woman affected with acquired Von Willebrand (VW) syndrome and intestinal angiodysplasias presented with severe gastrointestinal bleeding (hemoglobin 5 g/dl). Despite replacement therapy with VW factor/factor VIII concentrate qid, bleeding did not stop (eleven packed red blood cell units were transfused over three days). 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.

    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. PMID:24686099

    Acquired von Willebrand syndrome (AVWS) is a rare bleeding disorder with laboratory findings similar to those for congenital von Willebrand disease (VWD). Unlike the congenital disease, AVWS usually occurs in individuals with no personal or family history of bleeding. The prevalence of AVWS in the general population is unknown because data from large prospective studies of this syndrome are not available. Although AVWS is particularly frequent in lymphoproliferative or myeloproliferative disorders, it can also be associated with solid tumors, immunologic and cardiovascular disorders, and other miscellaneous conditions. Diagnosis of AVWS is based on assays measuring the activity of von Willebrand factor (VWF). This tends to be abnormally low, but factor VIII (FVIII) coagulant activity can sometimes be normal. FVIII/VWF inhibiting activity is found in only a minority of cases. Bleeding episodes in patients with AVWS are mostly of the mucocutaneous type and can be managed with desmopressin, plasma-derived FVIII/VWF concentrates, and intravenous immunoglobulin (IVIg). Recombinant activated factor VII can be useful in patients unresponsive to standard therapy. An updated version of the International Registry on AVWS, recently available online, will provide more information on this rare, but underdiagnosed and misdiagnosed, disorder. PMID:16427386

    Background Lemierre’s Syndrome (LS) is a highly aggressive rare disease process with a predilection for young, healthy adolescents. Often beginning with a primary cervicofacial infection, LS rapidly progresses to thrombophlebitis of the cerebral vasculature, metastatic infection, and septicemia. Untreated LS can be rapidly fatal. Thrombus within the cerebral vasculature can have devastating neurological effects. Advances in antibacterial therapy have resulted in a global decline in the incidence of LS, and clinicians may not consider LS early in the disease process. While the mortality of LS has declined, the morbidity associated with the disease has increased, particularly the neurological sequelae. Objectives This report will provide readers with a better understanding of the etiology, clinical presentation, evaluation methods, and appropriate treatment of LS. Case Report We present an atypical case of LS secondary to community-acquired methicillin-resistant Staphylococcus aureus (MRSA) infection progressing to bilateral cavernous sinus and ophthalmic vein thromboses with resultant binocular vision loss secondary to optic nerve and retinal ischemia. Conclusion This case highlights the importance of early recognition of LS in the setting of a community-acquired MRSA infection as the unifying condition in a young patient with multiple acute neurologic impairments.

    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.

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

    PubMed Central

    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.

    Since the detection of antibodies against the human immune deficiency virus (HIV) does not definitely prove HIV infection in hemophiliacs, virus detection was attempted by virus isolation from the peripheral blood monocytes (PBL), by demonstration of p24 antigen and decline of p24 antibody, and by detection of viral DNA by the polymerase chain reaction (PCR). Virus isolation was optimized by immediate coculture of PBL and by replacement of the reverse transcriptase test by the p24 antigen test, whereas the elimination of CD8+ lymphocytes proved to be unnecessary. Virus detection was dependent on the clinical stage of the illness. Virus isolation in 70 of 211 patients (33%) was more sensitive than detection of p24 antigen or decline of p24 antibody. PCR was performed in 25 patients and indicated infection in all of 15 isolation-positive cases and in 6 of 10 patients from whom virus was not isolated. Changes from negative to positive virus culture and from a weakly fusiogenic to a highly fusiogenic isolate were often accompanied by a progression of the disease. The results suggest that reactivation of HIV occurs when immune deficiency has become manifest. Apparently virus isolation detects only the virus already reactivated in vivo, whereas the PCR may also detect latent virus. PMID:2689596

    To better define the role of environmental factors on LDL phenotypic expression, the authors determined LDL patterns in patients with acquired immunodeficiency syndrome (AIDS), and infection characterized by hypertriglyceridemia and weight loss. Similar to previous studies, plasma triglyceride levels were increased, whereas plasma cholesterol, LDL cholesterol, and HDL cholesterol levels were decreased in the AIDS subjects compared to those in age-matched controls. The percentage of AIDS subjects with the LDL B phenotype was increased 2.5-fold, demonstrating an increased prevalence of the LDL B phenotype in an acquired form of hypertriglyceridemia. For each LDL phenotype in AIDS, serum triglyceride levels were higher than the same phenotypic pattern in controls, with the most marked elevations in triglycerides found in AIDS subjects with the LDL B phenotype. In contrast to what was observed in controls, HDL cholesterol levels were decreased in all AIDS subjects and were unrelated to LDL pattern. Total and LDL cholesterol levels were higher in controls with the LDL B phenotype than in those with the LDL A phenotype, but there was no difference in total and LDL cholesterol in AIDS subjects with LDL B compared to A. On multiple regression analysis in subjects with AIDS, plasma triglyceride levels, age, and HDL cholesterol all contribute to the occurrence of the LDL B phenotype, but elevations in plasma triglyceride levels are the strongest independent predictor. Body mass index was not a predictor of LDL B phenotype in AIDS. These results suggest that disturbances in triglyceride metabolism that are caused by AIDS lead to the appearance of the LDL subclass B phenotype and provide further evidence that environmental or disease states that perturb lipid metabolism can produce an increased prevalence of the LDL B phenotype. 35 refs., 1 fig., 5 tabs.

    Patients with monoclonal gammopathies of uncertain significance (MGUS) may develop an acquired bleeding disorder similar to congenital von Willebrand disease, called acquired von Willebrand syndrome (AvWS). In these patients, measures to improve hemostasis are required to prevent or treat bleeding episodes. We diagnosed 10 patients with MGUS and AvWS: 8 had IgGkappa (3) or lambda (5) MGUS and 2 IgM-kappa MGUS. Three therapeutic approaches were compared in them: (1) desmopressin (DDAVP), (2) factor VIII/von Willebrand factor (FVIII/vWF) concentrate, and (3) high-dose (1 g/kg/d for 2 days) intravenous Ig (IVIg). In patients with IgG-MGUS, DDAVP and FVIII/vWF concentrate increased factor VIII and von Willebrand factor in plasma, but only transiently. IVIg determined a more sustained improvement of the laboratory abnormalities and prevented bleeding during surgery (short-term therapy). In addition to the standard 2-day infusion protocol, a long-term IVIg therapy was performed in 2 patients with IgG-MGUS: repeated (every 21 days) single infusions of IVIg did improve laboratory abnormalities and stopped chronic gastrointestinal bleeding. On the other hand, IVIg failed to correct laboratories abnormalities in patients with IgM-MGUS. These comparative data obtained in a relative large and homogeneous group of patients with AvWS and MGUS confirm that DDAVP and FVIII/vWF concentrates improve the bleeding time (BT) and FVIII/vWF measurements only transiently, whereas IVIg provides a sustained treatment of AvWS associated with IgG-MGUS, but not with IgM-MGUS.

    A 52-year-old man with a medical history of intravenous drug abuse was admitted to our hospital with syncope due to torsades de pointes (TdP). Two days earlier, he had used methadone. The electrocardiogram showed a prolonged corrected QT interval (QTc) of 600 ms. Continuous telemetry observation showed multiple episodes of TdP. The patient was diagnosed with bradyarrhythmia-induced TdP with acquired long QT syndrome resulting from methadone use. The QTc normalised within 2 weeks after discontinuation of the methadone. In this case of a patient with opioid dependency, there is a reasonable risk of repeated methadone use. Therefore, implantable cardioverter defibrillator or pacemaker implantation is justified but risky because of possible infections when using intravenous drugs. Given the high mortality rates seen in untreated illicit opioid users, this patient needs an alternative pharmacological treatment. Buprenorphine is an opiate-receptor agonist associated with less QTc prolongation. The patient was referred to a rehab clinic and treated with an oral combination of buprenorphine and naloxone (Suboxone). During this therapy, his QTc remained normal. PMID:22020456

    The prevalence of Epstein-Barr virus (EBV) and human immunodeficiency virus (HIV) in acquired immunodeficiency syndrome (AIDS)-related primary central nervous system (CNS) lymphoma was examined. Deoxyribonucleic acid (DNA) extracted from 12 formalin-fixed, paraffin-embedded tumors was used as substrate for the polymerase chain reaction (PCR). Targets for amplification were the EBNA-1 region of EBV, the gag region of HIV, and a single copy cellular sequence as a control. The cases studied were autopsy and surgical specimens collected between the years 1985 and 1989. By the working formulation for non-Hodgkin's lymphomas, five had large cell, four had mixed large and small cleaved cell, two had small cleaved cell, and one had an unclassified histology. Epstein-Barr virus was detected in 6 of 12 tumors studied. Human immunodeficiency virus was not detected in any of the tumors. The presence of EBV was not correlated with any particular histologic tumor type. It is concluded that EBV, not HIV, can be detected in a large percentage (50%) of AIDS-related primary central nervous system (CNS) lymphomas. This viral association may be significant in light of the demonstrated ability of EBV to induce lymphoid tumors in experimental mammalian systems. Images Figure 1 Figure 2 PMID:1323221

    Acute thyroiditis is an extremely rare complication of nocardiosis. We report a patient with hyperthyroidism due to suppurative thyroiditis caused by Nocardia brasiliensis. A 38-year-old Black male presented with features of thyrotoxicosis, sepsis and airway obstruction. He had no evidence of underlying thyroid disease, but was severely immunocompromised as a result of acquired immunodeficiency syndrome. He had previously been diagnosed with pulmonary nocardiosis and also had nocardial abscesses on his anterior chest wall. Investigations revealed thyrotoxicosis, with a FT4 of 43.2 pmol/l and a suppressed TSH <0.01 mIU/l. Serum anti-thyroperoxidase and anti-thyroglobulin antibodies were absent. Computed tomography scan showed a large abscess in the anterior neck involving the left lobe and isthmus, as well as inhomogeneous changes in the right lobe of the thyroid. The radioisotopic scan showed absent uptake of tracer in keeping with thyroiditis. Although the initial presentation was that of hyperthyroidism, destruction of the gland later resulted in sustained hypothyroidism, necessitating thyroid hormone supplementation. The hyperthyroidism can be explained by the release of presynthesized and stored thyroid hormone into the circulation as a result of inflammation and disruption of the thyroid follicles, and the subsequent hypothyroidism by the fact that much of the gland was destroyed by the abscess and the extensive inflammatory process. This is the first documented case of hyperthyroidism in a patient with acute suppurative thyroiditis caused by Nocardia. PMID:24847469

    It is unclear whether seasonal influenza vaccination results in a net increase or decrease in the risk for Guillain-Barré syndrome (GBS). To assess the effect of seasonal influenza vaccination on the absolute risk of acquiring GBS, we used simulation models and published estimates of age- and sex-specific risks for GBS, influenza incidence, and vaccine effectiveness. For a hypothetical 45-year-old woman and 75-year-old man, excess GBS risk for influenza vaccination versus no vaccination was -0.36/1 million vaccinations (95% credible interval -1.22% to 0.28) and -0.42/1 million vaccinations (95% credible interval, -3.68 to 2.44), respectively. These numbers represent a small absolute reduction in GBS risk with vaccination. Under typical conditions (e.g. influenza incidence rates >5% and vaccine effectiveness >60%), vaccination reduced GBS risk. These findings should strengthen confidence in the safety of influenza vaccine and allow health professionals to better put GBS risk in context when discussing influenza vaccination with patients.

    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.

    The human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) epidemic is of unprecedented gravity and is spreading rapidly, notably in the most disadvantaged regions of the world. The search for a preventive vaccine is thus an absolute priority. For over 10 years the French National Agency for AIDS research (ANRS) has been committed to an original program combining basic science and clinical research. The HIV preventive vaccine research program run by the ANRS covers upstream research for the definition of immunogens, animal models, and clinical research to evaluate candidate vaccines. Most researchers in 2004 believe that it should be possible to obtain partial vaccine protection through the induction of a strong and multiepitopic cellular response. Since 1992, the ANRS has set up 15 phases I and II clinical trials in order to evaluate the safety and the capacity of the candidate vaccines for inducing cellular immune responses. The tested candidate vaccines were increasingly complex recombinant canarypox viruses (Alvac) containing sequences coding for certain viral proteins, utilized alone or combined with other immunogens (whole or truncated envelope proteins). ANRS has also been developing an original strategy based on the utilization of lipopeptides. These comprise synthetic fragments of viral proteins associated with lipids that facilitate the induction of a cellular immune response. These approaches promptly allowed the assessment of a prime-boost strategy combining a viral vector and lipopeptides. PMID:15867969

    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

    Acquired von Willebrand syndrome (AVWS) usually mimics von Willebrand disease (VWD) type 1 or 2A. However, in rare cases, the characteristics of other VWD types can predominate in AVWS that might require careful consideration of differential treatment options. The diagnosis and the treatment of a case of type 2B-like AVWS are discussed. Diagnosis of AVWS was ascertained by determining ristocetin cofactor activity, ristocetin-induced platelet aggregation, von Willebrand factor antigen, collagen binding and characterization of von Willebrand factor (VWF) multimers. Inhibitor presence was sought through mixing experiments, the Bethesda method, and calculation of the in-vivo recovery and plasma half-life of VWF after administration of factor VIII/VWF concentrate. Mutations in the A1 domain of VWF were ruled out by sequencing of exon 28 of the VWF gene. A 34-year-old male patient, putatively diagnosed with type 2B VWD, and undergoing laparoscopic cholecystectomy, did not respond adequately to perioperative hemostatic treatment with desmopressin and high doses of factor VIII/VWF concentrate, requiring the administration of recombinant activated factor VII. Further diagnostic workup revealed AVWS mimicking type 2B VWD, most likely owing to an autoantibody developed in the course of underlying monoclonal gammopathy of undetermined significance. The presence of AVWS should be considered before a diagnosis of type 2B VWD is made, especially in patients with a history atypical for inherited disease. PMID:21178586

    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.

    Background Familial sick sinus syndrome is associated with gene mutations and dysfunction of ion channels. In contrast, degenerative fibrosis of the sinus node tissue plays an important role in the pathogenesis of acquired sick sinus syndrome. There is a close relationship between transforming growth factor-β1 mediated cardiac fibrosis and acquired arrhythmia. It is of interest to examine whether transforming growth factor-β1 is involved in the pathogenesis of acquired sick sinus syndrome. Methods Overall, 110 patients with acquired SSS and 137 age/gender-matched controls were screened for transforming growth factor-β1 and cardiac sodium channel gene polymorphisms using gene sequencing or restriction fragment length polymorphism methods. An enzyme-linked immunosorbent assay was used to determine the serum level of transforming growth factor-β1. Results Two transforming growth factor-β1 gene polymorphisms (C-509T and T+869C) and one cardiac sodium channel gene polymorphism (H588R) have been identified. The C-dominant CC/CT genotype frequency of T869C was significantly higher in acquired sick sinus syndrome patients than in controls (OR 2.09, 95% CI 1.16–3.75, P = 0.01). Consistently, the level of serum transforming growth factor-β1 was also significantly greater in acquired sick sinus syndrome group than in controls (5.3±3.4 ng/ml vs. 3.7±2.4 ng/ml, P = 0.01). In addition, the CC/CT genotypes showed a higher transforming growth factor-β1 serum level than the TT genotype (4.25 ± 2.50 ng/ml vs. 2.71± 1.76 ng/ml, P = 0.028) in controls. Conclusion Transforming growth factor-β1 T869C polymorphism, correlated with high serum transforming growth factor-β1 levels, is associated with susceptibility to acquired sick sinus syndrome.

    Guanine-adenine-thymine-adenine 2 (GATA2) mutated disorders include the recently described MonoMAC syndrome (Monocytopenia and Mycobacterium avium complex infections), DCML (dendritic cell, monocyte, and lymphocyte deficiency), familial MDS/AML (myelodysplastic syndrome/acute myeloid leukemia) (myeloid neoplasms), congenital neutropenia, congenital lymphedema (Emberger's syndrome), sensorineural deafness, viral warts, and a spectrum of aggressive infections seen across all age groups. While considerable efforts have been made to identify the mutations that characterize this disorder, pathogenesis remains a work in progress with less than 100 patients described in current literature. Varying clinical presentations offer diagnostic challenges. Allogeneic stem cell transplant remains the treatment of choice. Morbidity, mortality, and social costs due to the familial nature of the disease are considerable. We describe our experience with the disorder in three affected families and a comprehensive review of current literature. PMID:25619630

    The number of patients with secondary immune deficiencies (SID) is on the rise, mostly since the arrival on the market of novel targeted therapies that have increased the survival rates of patients with hematological malignancies. The recent changes in the SID landscape have brought with them new and diverse medical needs that treatments for SID management should strive to meet. In this special report, we study the opportunities provided by facilitated subcutaneous immunoglobulin administration (fSCIg) to treat patients for whom the conventional routes (intravenous and subcutaneous) are sub-optimal. Experts in the treatment of SID describe real-life cases from their daily practice, in which fSCIg has led to reducing the burden of treatment and increasing the treatment satisfaction.

    Torsade de pointes is a rare but potentially fatal ventricular arrhythmia associated with drug-induced delayed repolarization and prolongation of the QT interval. To determine if the arrhythmogenic potential of noncardiac drugs can be assessed in vitro, we evaluated the effects of 12 drugs on the action potential duration (APD) of cardiac Purkinje fibers and compared results with clinical observations. APD changes in canine and porcine fibers were evaluated under physiologic conditions (37 degrees C, [K+]0 = 4 mM) using standard microelectrode techniques. Six of seven drugs associated with QT prolongation or torsade de pointes in man (cisapride, erythromycin, grepafloxacin, moxifloxacin, sertindole, and sotalol) affected concentration-dependent prolongation of the APD in canine fibers during slow stimulation (2-s basic cycle length), attaining greater than 15% prolongation at high concentrations (> or = 10-fold clinically encountered plasma levels). Each of five drugs not linked clinically to QT prolongation and torsade de pointes (azithromycin, enalaprilat, fluoxetine, indomethacin, and pinacidil) failed to attain 15% prolongation, with fluoxetine, indomethacin, and pinacidil abbreviating the APD. Drugs eliciting the greatest prolongation also demonstrated prominent reverse rate-dependent effects. The antihistamine terfenadine (linked to dose-dependent QT prolongation and torsade de pointes clinically) only minimally prolonged the APD in canine and porcine fibers (and exerted no effect on midmyocardial fibers from left ventricular free wall) at supratherapeutic concentrations. On the basis of concentration-dependent APD prolongation and reverse rate-dependent effects, this Purkinje fiber model detects six of seven drugs linked clinically to acquired long QT syndrome and torsade de pointes, and clears each of five drugs not associated with repolarization abnormalities (overall 92% accuracy), validating the utility of this Purkinje fiber model in the preclinical

    The acquired immunodeficiency syndrome (AIDS) was first recognized among hemophiliacs in 1982. The authors have conducted investigations to determine the onset and incidence of AIDS among hemophiliacs and to determine trends in hemophilia mortality since the introduction of clotting-factor concentrates in the late 1960s. A survey of United States hemophilia treatment centers, supported by the Centers for Disease Control and the National Hemophilia Foundation, defined a population of hemophiliacs which was monitored for AIDS cases through June 1984. Death reports from the United States Vital Statistics System and from the hemophilia treatment center survey provided mortality trends for 1968-1979 and for 1978-1982, respectively. The results of these investigations demonstrate the following points. 1) The AIDS epidemic is a new and important cause of illness and mortality among hemophiliacs, although a very low incidence of AIDS among hemophiliacs prior to 1982 cannot be ruled out. 2) The AIDS cases who attended the surveyed hemophilia treatment centers were distributed throughout the United States and were older than hemophilia treatment center patients without AIDS. AIDS cases also used more lyophilized clotting-factor concentrate, but only a small number of cases were reported with this information. 3) Improved care for hemophilia, including the use of clotting-factor concentrates, dramatically reduced hemophilia mortality rates during the 1970s. 4) In 1982, hemorrhage was the major cause of death among hemophiliacs. Deaths from non-alcoholic liver disease were also increased. AIDS incidence among hemophilia treatment center attendees was stable at 0.6 cases per 1,000 hemophilia treatment center attendees per year during 1982 and 1983 but increased sharply to 5.4 cases per 1,000 during the first quarter of 1984.

    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. PMID:3969698

    Acquired von Willebrand syndrome (AvWS) has been reported in eight children with Wilms tumor (nephroblastoma in four boys and four girls) at a mean age of 3.3 years (range, 0.33-9 years). Only three of eight patients with AvWS in Wilms tumor presented with mild mucocutaneous bleeding symptoms. The AvWS in seven children with Wilms tumor featured either undetectable or very low von Willebrand factor antigen (vWF.Ag) levels (mean, 3%) and decreased values for vWF ristocetin cofactor (RCF) activity (mean, 20%) and factor VIII coagulant (VIIIc) activity (mean, 16%). The response to 1-desamino-8-arginine vasopressin (DDAVP) was good in two and poor in one patient. Multimeric analysis of the vWF showed a normal pattern of type I von Willebrand disease (vWD) in three patients and an absence of multimers consistent with type III vWD in two patients. The higher functional levels, as compared with antigen levels, with increased ratios for factor VIIIc/vWFAg (mean, 5.3) and vWF.RCF/vWF.Ag (mean, 6.6) in seven patients with Wilms tumor are unexplained physiologically and are not consistent with type I vWF deficiency. The absence of vWD in the patient's family, and the return of factor VIII-vWF parameters to normal after chemotherapy or surgical removal of the Wilms tumor, support the diagnosis of AvWS causally related to the Wilms tumor. The causative agent is thought to be hyaluronic acid secreted by nephroblastoma cells of the Wilms tumor. Prospective studies to determine the nature of AvWS in children with Wilms tumor are warranted. PMID:11292185

    Cryptococcal meningitis is one of the most lethal fungal infections in patients with acquired immune deficiency syndrome (AIDS). The incidence of and mortality from cryptococcal meningitis have markedly decreased since the introduction of combination antiretroviral therapy (cART). However, despite its benefits, the initiation of cART results in immune reconstitution inflammatory syndrome (IRIS) in some patients. Although IRIS is occasionally difficult to distinguish from relapse or treatment failure, the distinction is important because IRIS requires a different treatment. Here, we present the case of a patient with AIDS who developed symptoms of cryptococcal IRIS 41 months after starting cART. To the best of our knowledge, the time between cART initiation and the onset of cryptococcal IRIS in this patient is the longest that has been reported in the literature. PMID:26425133

    Morbidity and mortality of suppurative bacterial meningitis show a very constant behavior over many decades. The introduction of antibiotics certainly lowered the lethality considerably, but since then it has remained fairly unchanged at about 15-20%. However, in the principal groups of pathogens--meningococci, pneumococci, Haemophilus influenzae--antibiotic resistence plays no special role. The significance of disorders of defense against infections for the course of the disease has not yet been investigated. Of 92 children examined with purulent meningitis, 49 showed a selective antibody deficiency syndrome against bacterial antigens, 38 of 48 children investigated showed further disorders of bactericidal activity. The proportion of these disorders is particularly high in children with defective healing of a meningitis. PMID:826806

    Objectives Patients with the acquired immunodeficiency syndrome (AIDS) have an abnormality of retina/optic nerve function, manifested as decreased contrast sensitivity (in the absence of ocular opportunistic infections or media opacity), abnormalities on automated perimetry, and loss of retinal nerve fiber layer, even among those with good visual acuity, termed the HIV-neuroretinal disorder. The objectives of this study were to determine the prevalence, incidence, risk factors for, and outcomes of HIV-neuroretinal disorder. Design Prospective cohort study Participants 1822 patients with AIDS without ocular infections or media opacities. Methods Patients with HIV-neuroretinal disorder were identified by a contrast sensitivity < 1.50 log units in either eye in the absence of ocular opportunistic infections or media opacity. Main outcome measures Incidence of HIV-neuroretinal disorder, mortality, visual impairment (visual acuity 20/50 or worse), and blindness (20/200 or worse) on logarithmic visual acuity charts. Results Sixteen percent of participants had HIV-neuroretinal disorder at enrollment. The estimated cumulative incidence by 20 years after AIDS diagnosis was 51% (95% confidence interval [CI] 46%–55%). HIV-neuroretinal disorder was more common in women and African American persons. Risk factors for it included hepatitis C infection, low CD4+ T cells, and detectable HIV RNA in the blood. Patients with HIV neuroretinal disorder had a 70% excess mortality vs. those without it, even after adjusting for CD4+ T cells and HIV load (hazard ratio=1.7, 95% CI= 1.3–2.1, P<0.0001). Patients with HIV-neuroretinal disorder had increased risks of bilateral visual impairment (hazard ratio=6.5, 95% CI=2.6–10.6, P<0.0001) and blindness (hazard ratio=5.9, 95% CI=2.8–13.7, P=0.01) vs. those without HIV neuroretinal disorder. Conclusions HIV-neuroretinal disorder is a common finding among patients with AIDS, and it is associated with an increased mortality and an increased

    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

    The immune deficiency (Imd) signaling pathway is activated by Gram-negative bacteria for producing antimicrobial peptides (AMPs). In Drosophila melanogaster, the activation of this pathway is initiated by the recognition of Gram-negative bacteria by peptidoglycan (PGN) recognition proteins (PGRPs), PGRP-LC and PGRP-LE. In this study, we found that the Imd pathway is involved in enhancing the promoter activity of AMP gene in response to Gram-negative bacteria or diaminopimelic (DAP) type PGNs derived from Gram-negative bacteria in an immune responsive silkworm cell line, Bm-NIAS-aff3. Using gene knockdown experiments, we further demonstrated that silkworm PGRP L6 (BmPGRP-L6) is involved in the activation of E. coli or E. coli-PGN mediated AMP promoter activation. Domain analysis revealed that BmPGRP-L6 contained a conserved PGRP domain, transmembrane domain, and RIP homotypic interaction motif like motif but lacked signal peptide sequences. BmPGRP-L6 overexpression enhances AMP promoter activity through the Imd pathway. BmPGRP-L6 binds to DAP-type PGNs, although it also binds to lysine-type PGNs that activate another immune signal pathway, the Toll pathway in Drosophila. These results indicate that BmPGRP-L6 is a key PGRP for activating the Imd pathway in immune responsive silkworm cells. PMID:26991439

    Cisplatin, paclitaxel and bortezomib are effective chemotherapy drugs in cancer treatment. However, they share severe peripheral neurotoxicity (PN) as one of their major dose-limiting side effects, often impairing cancer patients' quality of life and sometimes being permanent. Even if preclinical oncology is largely based on the use of immune-deficient mice, rodent models used to study the chemotherapy-induced PN are available only in immune-competent animals. In this study we characterized for the first time the PN induced by these chemotherapies through neurophysiological, behavioral, morphological and morphometric studies in athymic nude mice, a commonly employed strain in the preclinical oncology. The animals, divided into four groups, were chronically treated with cisplatin, paclitaxel or bortezomib once or twice a week for 4 or 6 weeks or were left untreated. These schedules were tolerated, neurotoxic and in the range of antineoplastic effectiveness. Despite similarities, differences in the features of PN were evident if compared with immune-competent models under comparable regimens of treatment. The results of this study may provide a basis for future combined analysis of antineoplastic and neurotoxic effects of chemotherapy in the same animals. PMID:25450467

    Patients can develop malignancies due to various reasons including genetic factors, chemical carcinogens, radiation, and defects in their immune system. The immune system is postulated to carry out routine surveillance for malignancy. Patients who have defective immune responses may be susceptible to malignancies due to complicated underlying mechanisms. These include defective immune response to cancer-causing bacteria, transforming viruses, and concomitant molecular, cellular and immunoregulatory defects. Common variable immune deficiency (CVID) is characterized by hypogammaglobulinemia, impaired antibody responses and an increased susceptibility to infections. A disorderly immune response, or immune dysregulation, may also lead to autoimmune complications and possibly to malignancy. The treatment of CVID involves infusion of replacement doses of immunoglobulin, either intravenously (IGIV) or subcutaneously (SCIG). However, it is unclear whether adequate replacement of immunoglobulins is sufficient to prevent the increased risk of malignancy seen in this disease. We present two cases of unusual solid tumors complicating CVID treated with adequate doses of intravenous immunoglobulins. In this study we review the occurrence of malignancy in patients with CVID and postulate mechanisms that may be involved indigent to this disease. We will also review the role of replacement immunoglobulin and discuss cancer screening in these high risk individuals. PMID:22746346

    The acquired immunodeficiency syndrome (AIDS) wasting syndrome (AWS) is a devastating complication of human immunodeficiency virus infection characterized by a disproportionate decrease in lean body mass. The pathogenesis of the AWS is unknown, but recent data suggest that endogenous secretion of the potent anabolic hormone, testosterone; is decreased in 30-50% of men with AIDS. However, it is unknown whether decreased androgen levels are associated with decreased lean body mass and/or functional decreases in muscle strength and aerobic capacity in hypogonadal men with the AWS. In addition, testosterone is known to have stimulatory effects on GH secretion, and the loss of these effects on the GH-insulin-like growth factor I (IGF-I) axis may be an additional mechanism of decreased lean body mass in this population. Twenty hypogonadal subjects (free-testosterone < 12 pg/mL) with weight loss > 10% of preillness weight or absolute weight < 90% ideal body weight (IBW) were enrolled in the study. None of the subjects were receiving Megace. Lean body mass and fat-free mass were determined by potassium-40 isotope analysis (40K) and dual-energy x-ray absorptiometry, respectively, and analyzed with respect to gonadal function by linear regression analysis. Muscle mass was determined by urinary creatinine excretion, and exercise functional capacity was assessed by a 6-min walk test, a sit-to-stand test, and a timed get-up-and-go test. Results also were compared with gonadal function by regression analysis. IGF-I and mean overnight GH levels, determined from frequent sampling (q20 min from 2000-0800 h), were compared with results obtained from age- and sex-matched normal controls. Subjects were 26-58 yr of age (39 +/- 7 yr, mean +/- SD) with a CD4 cell count of 150 +/- 186 cells/mm3. Serum levels of FSH were elevated in 30% of the subjects.

    Acquired von Willebrand syndrome (AVWS) is an acquired bleeding disorder with clinical and laboratory features similar to those of the inherited form of the disease. AVWS is reported in many disorders, most frequently in myeloproliferative neoplasms and in, among others, essential thrombocythemia (ET). Interestingly, ET is associated with both the thrombotic and haemorrhagic complications, which occur in 20 % and 5-30 % of patients, respectively. The present report concerns a 38-year-old man, suffering from ET, who presented with two episodes of post-arthroscopic joint bleeding after synovectomy required for the treatment of synovial hypertrophy and chronic left knee joint synovitis. We discuss the current diagnostic approaches, as well as the risk factors predisposing to bleeding and its management, in patients with essential thrombocythemia. PMID:25432436

    In a group of HIV positive young male patients without any significant neuropsychiatric signs, computer-analyzed EEG (CEEG) and Dynamic Brain Mapping evaluations were conducted. These patients, who only had micro-neuropsychiatric symptoms, demonstrated CEEG profiles that more closely resemble those of patients diagnosed as suffering from mild dementia than age-related normals from our CEEG data base. The CEEGs of patients diagnosed as having Acquired Immune Deficiency Syndrome (AIDS), compared to patients with HIV positive, showed greater similarity in CEEG patterns to severely demented patients than to normal control groups. The findings of this pilot study suggest that CEEG may be useful for early determination of the Central Nervous System's (CNS) involvement with the AIDS virus and monitoring the progress of the illness.

    To estimate the incidence of adverse drug reactions (ADRs) in Human immune deficiency virus (HIV) patients on highly active antiretroviral therapy (HAART). To identify the risk factors associated with ADRs in HIV patients. To analyze reported ADRs based on various parameters like causality, severity, predictability, and preventability. Retrospective case-control study. An 18-month retrospective case-control study of 208 patients newly registered in ART center, RIMS hospital, Kadapa, were intensively monitored for ADRs to HAART. Predictability was calculated based on the history of previous exposure to drug. Multivariate logistic regressions were used to identify the risk factors for ADRs. Data were analyzed using the chi-square test for estimating the correlation between ADRs and different variables. All statistical calculations were performed using EpiInfo version 3.5.3. Monitoring of 208 retrospective patients by active Pharmacovigilance identified 105 ADRs that were identified in 71 patients. Skin rash and anemia were the most commonly observed ADRs. The organ system commonly affected by ADR was skin and appendages (31.57%). The ADRs that were moderate were 90.14% of cases. The incidence of ADRs (53.52%) was higher with Zidovudine + Lamivudine + Nevirapine combination. CD4 cell count less than <250 cells/μl were 80.28%, male gender were observed to be the risk factors for ADRs. Our study finding showed that there is a need of active pharmaceutical care with intensive monitoring for ADRs in Indian HIV-positive patients who are illiterate, of male and female gender, with CD4 count ≤250 cells/mm(3) with comorbid conditions.

    Methicillin-resistant Staphylococcus aureus (MRSA) clones harboring the toxic shock syndrome toxin 1 (tst) gene have been detected in France and in Switzerland since 2002. During a passive survey conducted between 2002 and 2003, we collected 103 tst-positive S. aureus isolates from 42 towns in France, of which 27 were resistant to methicillin. The tst-positive MRSA belonged to two clones: a major clone comprising 25 isolates of sequence type (ST) 5 and agr group 2 and a minor clone comprising two isolates of ST30 and agr3. The tst-positive MRSA clones were associated with both hospital-acquired (12 cases) and community-acquired (8 cases) infections. The MRSA clones were mainly isolated from children (overall median age, 3 years). They caused a variety of clinical syndromes, including toxic shock syndrome and suppurative infections. Both clones were found to harbor a type IV staphylococcal chromosomal cassette mec (SCCmec) and to have similar antibiotic resistance profiles (usually resistant to oxacillin, kanamycin, and tobramycin and with intermediate resistance to fusidic acid). The origin of these clones is unclear. The tst-positive agr2 MRSA clone has the same sequence type (ST5) of two pandemic nosocomial MRSA clones, namely, the Pediatric clone and the New York/Japan clone. These findings suggest that all these clones are phylogenetically related. The pulsotype of the tst-positive MRSA clones differed from that of methicillin-sensitive S. aureus (MSSA) clones by a single band involving the SCCmec element. These findings suggest that the tst-positive MRSA clones may have emerged from their respective MSSA counterparts. PMID:16517865

    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 (aLQTS). We developed a computational approach to reveal the pharmacological properties of I(Kr) blocking drugs that are most likely to cause aLQTS in the setting of subtle alterations in I(Kr) channel gating that would be expected to result from benign genetic variants.Weused themodel to predict themost 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 I(Kr) channels, corresponding to activation, inactivation, deactivation and recovery from inactivation of I(Kr) channels. We then screened and identified the properties of I(Kr) blockers that caused acquired long QT and therefore unmasked mutant phenotypes formild,moderate and severe variants. Mutant I(Kr) 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 I(Kr)-drug interactions in order to identify the characteristics that selectively exacerbate the AP duration (APD) differences between wild-type and I(Kr) mutated cells.

    Patients with acquired immunodeficiency syndrome (AIDS) have been reported to develop abnormalities of the endocrine system and in particular of the hypothalamic-pituitary-adrenal (HPA) axis. To define the abnormalities of HPA function in AIDS patients better, we performed ACTH and ovine corticotropin-releasing hormone (oCRH) testing in a group of AIDS patients and oCRH testing in a group of healthy subjects. Our study found that in AIDS patients with normal ACTH testing, oCRH testing revealed a variety of subclinical abnormalities of ACTH and cortisol responses. Although we did not find frank adrenal insufficiency in any of these AIDS patients, it remains to be determined if any of the subclinical abnormalities we identified are predictive of clinically significant adrenal insufficiency; it may be that as AIDS patients live longer, the subclinical abnormalities will progress to adrenal insufficiency.

    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.

    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/mm3: 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. PMID:26798547

    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.

    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). PMID:26631594

    PubMed Central

    2014-01-01

    Background Lemierre's syndrome is a rare condition characterized by thrombophlebitis of internal jugular vein, septicemia and septic metastatic infection of different organs. It is preceded by an oropharyngeal infection by anaerobic organisms. Community-acquired methicillin-resistant Staphylococcus aureus is now emerging as a causative organism in Lemierre's syndrome. Clinical manifestations vary depending on the organ system affected by the infection. Although rare, patients may present with life-threatening conditions such as cardiac tamponade. Case presentation We report the first case, to our knowledge, of Lemierre's syndrome presenting with cardiac tamponade secondary to community-acquired methicillin-resistant S. aureus in a previously well 45-year-old Sri Lankan lady. Fever, sore throat and left-sided neck pain complicated with facial and left upper limb swelling were followed by severe shortness of breath for 24 h. There was tachycardia with pulsus paradoxus, low blood pressure and soft heart sounds. Pericardial effusion with cardiac tamponade was detected on echocardiogram and methicillin-resistant S. aureus species were isolated in both blood and pericardial fluid cultures. Venous duplex of neck veins and computed tomography scan of the neck showed thrombosis of left-sided internal jugular, external jugular, subclavian and axillary veins. Diagnosis of Lemierre's syndrome was made, and patient had a satisfactory recovery following emergency pericardiocentesis and a prolonged course of antibiotics. Conclusions Although uncommon, Lemierre's syndrome is a life-threatening condition. Patients may present with cardiac tamponade secondary to purulent pericarditis in Lemierre's syndrome, where emergency pericardiocentesis is lifesaving. Community-acquired methicillin-resistant S. aureus is emerging as a causative agent in Lemierre's syndrome, and awareness is required amongst physicians for prompt diagnosis and appropriate empirical treatment to prevent mortality

    Severe combined immune deficiency due to adenosine deaminase (ADA) deficiency is a rare, potentially fatal pediatric disease, which results from mutations within the ADA gene, leading to metabolic abnormalities and ultimately profound immunologic and nonimmunologic defects. In this study, recombinant adeno-associated virus (rAAV) vectors based on serotypes 1 and 9 were used to deliver a secretory version of the human ADA (hADA) gene to various tissues to promote immune reconstitution following enzyme expression in a mouse model of ADA deficiency. Here, we report that a single-stranded rAAV vector, pTR2-CB-Igκ-hADA, (1) facilitated successful gene delivery to multiple tissues, including heart, skeletal muscle, and kidney, (2) promoted ectopic expression of hADA, and (3) allowed enhanced serum-based enzyme activity over time. Moreover, the rAAV-hADA vector packaged in serotype 9 capsid drove partial, prolonged, and progressive immune reconstitution in ADA-deficient mice. Overview Summary Gene therapies for severe combined immune deficiency due to adenosine deaminase (ADA) deficiency (ADA-SCID) over two decades have exclusively involved retroviral vectors targeted to lymphocytes and hematopoietic progenitor cells. These groundbreaking gene therapies represented an unprecedented revolution in clinical medicine but in most cases did not fully correct the immune deficiency and came with the potential risk of insertional mutagenesis. Alternatively, recombinant adeno-associated virus (rAAV) vectors have gained attention as valuable tools for gene transfer, having demonstrated no pathogenicity in humans, minimal immunogenicity, long-term efficacy, ease of administration, and broad tissue tropism (Muzyczka, 1992 ; Flotte et al., 1993 ; Kessler et al., 1996 ; McCown et al., 1996 ; Lipkowitz et al., 1999 ; Marshall, 2001 ; Chen et al., 2003 ; Conlon and Flotte, 2004 ; Griffey et al., 2005 ; Pacak et al., 2006 ; Stone et al., 2008 ; Liu et al., 2009 ; Choi et al., 2010

    A T-cell tropic retrovirus, simian immunodeficiency virus (SIV), has recently been isolated from immunodeficient rhesus monkeys. This virus has remarkable similarities to human immunodeficiency virus (HIV), the etiologic agent of acquired immunodeficiency syndrome. Subsequent studies of simian infection with SIV have shown it to be a relevant animal model for studying the pathogenesis of AIDS in man. In both HIV-infected humans and SIV-infected monkeys, a cutaneous maculopapular eruption has been described. To date, the pathogenesis and possible relationship of these exanthema to the evolution of systemic immunosuppression have remained obscure. In this study, the mononuclear cell infiltrates that characterize skin rashes of SIV-infected rhesus monkeys were found to be composed predominantly of cells with phenotypic characteristics of cytotoxic/suppressor (T8+) lymphocytes and natural killer cells. Many of these cells expressed membrane-bound interleukin-2 receptor molecules. Double labeling and immunoelectron microscopy revealed these cells in direct contact with degenerative Langerhans cells within the epidermis and dermis. These observations suggest that the cutaneous rash associated with SIV infection may be the consequence of target cell injury of Langerhans cells by effector cells with cytotoxic potential.

    Although antiretroviral therapy has made human immunodeficiency virus (HIV) infection a controllable disease, it is still unclear how viral replication persists in untreated patients and causes CD4(+) T-cell depletion leading to acquired immunodeficiency syndrome (AIDS) in several years. Theorists tried to explain it with the diversity threshold theory in which accumulated mutations in the HIV genome make the virus so diverse that the immune system will no longer be able to recognize all the variants and fail to control the viraemia. Although the theory could apply to a number of cases, macaque AIDS models using simian immunodeficiency virus (SIV) have shown that failed viral control at the set point is not always associated with T-cell escape mutations. Moreover, even monkeys without a protective major histocompatibility complex (MHC) allele can contain replication of a super infected SIV following immunization with a live-attenuated SIV vaccine, while those animals are not capable of fighting primary SIV infection. Here we propose a recursion-based virus-specific naive CD4(+) T-cell depletion hypothesis through thinking on what may happen in individuals experiencing primary immunodeficiency virus infection. This could explain the mechanism for impairment of virus-specific immune response in the course of HIV infection. PMID:27515208

    The Texas Center for Health Disparities, a National Institute on Minority Health and Health Disparities Center of Excellence, presents an annual conference to discuss prevention, awareness education and ongoing research about health disparities both in Texas and among the national population. 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. PMID:24227993

    Sudden acquired retinal degeneration syndrome (SARDS) is one of the leading causes of currently incurable canine vision loss diagnosed by veterinary ophthalmologists. The disease is characterized by acute onset of blindness due to loss of photoreceptor function, extinguished electroretinogram with an initially normal appearing ocular fundus, and mydriatic pupils which are slowly responsive to bright white light, unresponsive to red, but responsive to blue light stimulation. In addition to blindness, the majority of affected dogs also show systemic abnormalities suggestive of hyperadrenocorticism, such as polyphagia with resulting obesity, polyuria, polydipsia, and a subclinical hepatopathy. The pathogenesis of SARDS is unknown, but neuroendocrine and autoimmune mechanisms have been suggested. Therapies that target these disease pathways have been proposed to reverse or prevent further vision loss in SARDS-affected dogs, but these treatments are controversial. In November 2014, the American College of Veterinary Ophthalmologists' Vision for Animals Foundation organized and funded a Think Tank to review the current knowledge and recently proposed ideas about disease mechanisms and treatment of SARDS. These panel discussions resulted in recommendations for future research strategies toward a better understanding of pathogenesis, early diagnosis, and potential therapy for this condition.

    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.

    Purified helper-inducer (T4+) and suppressor-cytotoxic (T8+) lymphocytes from eight patients with acquired immunodeficiency syndrome (AIDS) and eight healthy heterosexual donors were examined by limiting dilution analysis for their ability to be clonally expanded. It was demonstrated that viable T4+ and T8+ lymphocytes from patients with AIDS had markedly reduced proportions of clonable cells compared to the healthy donors (T4 = 1:255 vs. 1:34, P = 0.06; T8 = 1:355 vs. 1:55, P = 0.01). However, the cloned T cells that were obtained from the patients with AIDS demonstrated normal proliferation in response to phytohemagglutinin and alloantigen, and normal ability to help or suppress pokeweed mitogen-driven IgG synthesis. These results strongly suggest that, in addition to a quantitative diminution of T4+ lymphocytes in AIDS, there is an intrinsic functional defect in the surviving T4+ and T8+ lymphocytes, which is reflected by a severe decrease in their potential for clonal expansion.

    Background: Identifying factors, which influence health behaviors is critical to designing appropriate and effective preventive programs. Human immunodeficiency virus (HIV) transmission is highly related to people behaviors and understanding factors influencing healthy behaviors among Iranian people living with HIVs (PLHIVs)/acquired immunodeficiency syndrome (AIDS) is very important to tailor an effective response to HIV/AIDS epidemic. Methods: This study was conducted as a qualitative study by methods of focus group discussion and in-depth interview in six provinces of Iran with 64 PLHIVs to determine factors influence engagement in positive prevention. Results: Knowledge and education, feelings of responsibility and positive prevention practices were identified as the primary domains of engagement. These domains were found to be influenced by feelings of ostracism and frustration, poverty, barriers to disclosure of HIV status, access to and utilization of drug abuse treatment services and antiretroviral therapy, adherence to treatment, age, religiousness, sex work, singleness, and incarceration. Conclusions: Designing new interventions and updating current interventions directed toward the aforementioned factors should be addressed by responsible Iranian authorities in order to have a national effective response on the HIV/AIDS epidemic.

    Acquired von Willebrand syndrome (AVWS) has been associated mainly with monoclonal gammopathy of uncertain significance (MGUS), clonal lymphoproliferative or myeloproliferative disorders and autoimmunity. In the present work we studied 6 patients with AVWS: four with MGUS IgG (lambda or kappa), one with small lymphocytic lymphoma and one with agnogenic myeloid metaplasia (AMM). All the patients underwent a pharmacokinetic analysis at presentation in order to study potential differences in recovery, clearance (CL) or terminal half-life (THL) following administration of von Willebrand factor (VWF) concentrate. In all the patients with AVWS an increase in clearance and a decrease in THL was observed as compared to these parameters in patients with hereditary type 3 von Willebrand disease (VWD). No difference in recovery was observed among the groups. The increase in clearance and the decrease in THL were significantly more pronounced in the group of MGUS patients (57.93 +/- 25.6 ml/h/kg, and 1.39 +/- 0.5 h, respectively) as compared to these parameters in the AMM (8.06 ml/h/kg, and 6.96 h, respectively) or the lymphoma (4.76 ml/h/kg, and 6.76 h. respectively) patients (p = 0.03 for clearance and 0.001 for THL). These data indicate that the pharmacokinetic analysis can be a useful tool to distinguish between MGUS-related and other causes of AVWS, and to plan an appropriate treatment accordingly.

    A 4-year study of a boy with combined immune deficiency is presented, and the impact of this disease on various aspects of his growth and development is examined. There is no evidence of immune deficiency in either parent or in the genetic background on the maternal side. Three children of a brother of the mother's father may have had immune deficiencies but two have grown to be teenagers with no problems. Another died. At autopsy, however, lymph nodes appeared normal. The deceased older brother had severe combined immune deficiency (SCID). The autopsy findings showed Pneumocystis carinii pneumonia to be the direct cause of death and these findings contributed to the diagnosis of SCID. After a successful germ-free birth, the male infant (DV) was placed in the isolator. Laboratory tests were normal except that the x-rays showed no thymic shadow, his absolute lymphocyte count ranged from 399-440/mm and the lymphocytes showed no proliferative response to phytohemagglutinin (PHA). Specific tests showed the antibody-producing immune system and the cell-mediated immune system to be severely defective. The patient's lymphocytes elicited positive responses by lymphocytes from father, mother, and sister. Subsequent search in national and international tissue-typing laboratories has shown four HLA matches but none has been nonreactive in mixed lymphocyte culture (MLC). therefore, this patient has remained in isolation to the present; now he is 4 years old. Approximately 35 species of microorganisms, mostly transient contaminants, have been isolated, taking into account that the same organism may have been identified under different names in different laboratories. Those isolated frequently and in sufficiently high concentration to indicate colonization have been speciated as follows: anaerobes-Propionibacterium acnes, Lactobacillus catenaforme (disappeared spontaneously), Bacteroides oralis ss. elongatus, Clostridium (perenne, hastiforme, bifermentans), Bacteroides

    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.

    Progressive multifocal leukoencephalopathy (PML) is a fatal demyelinating disease of the central nervous system (CNS) caused by the human polyomavirus JC (JCV). JCV has a hypervariable noncoding transcriptional control region (TCR) that spans the origin of replication of the JCV genome through to the first ATG start codon for late gene transcription. The archetype form of TCR is frequently found in the urine and kidneys of healthy and immunocompromised subjects. However the rearranged forms, whose prototype is Mad-1, possibly generated by deletion and duplication of segments of the archetype sequence, are found in the brain and cerebrospinal fluid (CSF) of PML patients. In this study the authors compared JCV TCR detected in paired CSF, plasma, and urine samples of 11 acquired immunodeficiency syndrome (AIDS) patients affected by PML to try to determine where the rearranged JCV TCRs are selected. In one patient, it was also possible to amplify and sequence the TCR in the brain and lymphocytes. Moreover, in 5/11 patients, the CSF, plasma, and urine samples corresponding to 2 months after PML development were available; and in another patient, it was possible to sequence the TCR in plasma and lymphocytes sampled 8 months before the onset of PML. The presence of the same TCR sequences in all the CSF and plasma samples taken from individual patients could strengthen the hypothesis that the blood is a compartment where JCV may replicate and undergo rearrangement of the TCR. This further supports the hypothesis that JCV reaches the brain by a hematogenous route and indicates that the JCV TCR sequences detected in plasma could be used as an early marker of JCV pathogenicity before the clinical appearance of PML in immunocompromised patients.

    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

  4. Recommendations for assisting in the prevention of perinatal transmission of human T-lymphotropic virus type III/lymphadenopathy-associated virus and acquired immunodeficiency syndrome.

    1985-12-01

    The majority of cases of pediatric acquired immunodeficiency syndrome (AIDS) are transmitted perinatally. 165 (76%) of the cases of AIDS in children under 13 years of age reported as of December 1, 1985, in the US had as the only known risk factor a mother from a high-risk group. However, perinatal transmission from an infected mother to her infant is not automatic; studies have placed the rate of transmission from 0%-65%. A concern in addition to the risk posed to infants born to infected mothers is evidence of an increased likelihood of developing full-blown AIDS when infection with the AIDS virus occurs in association in pregnancy. Target groups for counseling and testing for antibodies to the AIDS virus should include pregnant women or those who may become pregnant who already have evidence of AIDS infection, are intravenous drug abusers, were born in countries where there is a high rate of heterosexual transmission of AIDS, are prostitutes, or are the sexual partners of men in high-risk groups. Such counseling and testing should be made available through the settings that women at increased risk frequent, including drug abuse treatment programs and sexually transmitted diseases clinics. Infected women should be advised to delay pregnancy until more is known about the perinatal transmission of AIDS. Pregnancy infected women should be closely monitored for the development of opportunistic infections as well as psychosocial difficulties. Although these recommendations pertain to women, men who are infected with the AIDS virus also should be counseled about risks of perinatal transmission. PMID:2999576

    Cutaneous hyperpigmentations are frequent complaints, motivating around 8.5% of all dermatological consultations in our country. They can be congenital, with different patterns of inheritance, or acquired in consequence of skin problems, systemic diseases or secondary to environmental factors. The vast majority of them are linked to alterations on the pigment melanin, induced by different mechanisms. This review will focus on the major acquired hyperpigmentations associated with increased melanin, reviewing their mechanisms of action and possible preventive measures. Particularly prominent aspects of diagnosis and therapy will be emphasized, with focus on melasma, post-inflammatory hyperpigmentation, periorbital pigmentation, dermatosis papulosa nigra, phytophotodermatoses, flagellate dermatosis, erythema dyschromicum perstans, cervical poikiloderma (Poikiloderma of Civatte), acanthosis nigricans, cutaneous amyloidosis and reticulated confluent dermatitis PMID:24626644

    Over one third of the patients sero-positive for the human immunodeficiency virus (HIV) with signs of the acquired immune deficiency syndrome (AIDS), and under treatment with anti-retroviral therapy (ART), develop the immune reconstitution inflammatory syndrome (IRIS). It is not clear what variables are that determine whether a patient with HIV/AIDS will develop ART-related IRIS, but the best evidence base thus far indicates that HIV/AIDS patients with low CD4 cell count, and HIV/AIDS patients whose CD4 count recovery shows a sharp slope, suggesting a particularly fast "immune reconstitution", are at greater risk of developing IRIS. Here, we propose the hypothesis that one important variable that can contribute to low CD4 cell count number and function in ART-treated HIV/AIDS patients is altered hypothalamic-pituitary-adrenal (HPA) cell-mediated immune (CMI) regulation. We discuss HPA-CMI deregulation in IRIS as the new frontier in comparative effectiveness research (CRE) for obtaining and utilizing the best evidence base for treatment of patients with HIV/AIDS in specific clinical settings. We propose that our hypothesis about altered HPA-CMI may extend to the pathologies observed in related viral infection, including Zika PMID:27212842

    Background Today’s rapid growth of migrant populations has been a major contributor to the human immunodeficiency virus (HIV) epidemic. However, relatively few studies have focused on HIV/acquired immunodeficiency syndrome (AIDS)-related knowledge, attitudes, and practice among rural-to-urban migrants in China. This cross-sectional study was to assess HIV/AIDS-related knowledge and perceptions, including knowledge about reducing high-risk sex. Methods Two-phase stratified cluster sampling was applied and 2,753 rural migrants participated in this study. An anonymous self-administered questionnaire was conducted in Guangdong and Sichuan provinces in 2007. Descriptive analysis was used to present the essential characteristics of the respondents. Chi-square test and multiple logistic regression models were performed to examine the associations between identified demographic factors and high-risk sex, sexually transmitted disease (STD) symptoms, and access to HIV screening services among the seven types of workers. Results 58.6% of participants were knowledgeable about HIV/AIDS transmission, but approximately 90% had a negative attitude towards the AIDS patients, and that 6.2% had engaged in high-risk sex in the past 12 months. Logistic regression analysis revealed sex, marital status, income, migration and work experience to be associated with high-risk sex. Among the 13.9% of workers who reported having STD symptoms, risk factors that were identified included female gender, high monthly income, being married, daily laborer or entertainment worker, frequent migration, and length of work experience. Only 3% of migrant workers received voluntary free HIV screening, which was positively associated with monthly income and workplace. Conclusions HIV/AIDS knowledge, attitudes, and practices among rural migrants in China remain a thorny health issue, and use of healthcare services needs to be improved.

    Primary immunodeficiency diseases comprise a group of heterogeneous genetic defects that affect immune system development and/or function. Here we use in vitro differentiation of human induced pluripotent stem cells (iPSCs) generated from patients with different recombination-activating gene 1 (RAG1) mutations to assess T-cell development and T-cell receptor (TCR) V(D)J recombination. RAG1-mutants from severe combined immunodeficient (SCID) patient cells showed a failure to sustain progression beyond the CD3(--)CD4(-)CD8(-)CD7(+)CD5(+)CD38(-)CD31(-/lo)CD45RA(+) stage of T-cell development to reach the CD3(-/+)CD4(+)CD8(+)CD7(+)CD5(+)CD38(+)CD31(+)CD45RA(-) stage. Despite residual mutant RAG1 recombination activity from an Omenn syndrome (OS) patient, similar impaired T-cell differentiation was observed, due to increased single-strand DNA breaks that likely occur due to heterodimers consisting of both an N-terminal truncated and a catalytically dead RAG1. Furthermore, deep-sequencing analysis of TCR-β (TRB) and TCR-α (TRA) rearrangements of CD3(-)CD4(+)CD8(-) immature single-positive and CD3(+)CD4(+)CD8(+) double-positive cells showed severe restriction of repertoire diversity with preferential usage of few Variable, Diversity, and Joining genes, and skewed length distribution of the TRB and TRA complementary determining region 3 sequences from SCID and OS iPSC-derived cells, whereas control iPSCs yielded T-cell progenitors with a broadly diversified repertoire. Finally, no TRA/δ excision circles (TRECs), a marker of TRA/δ locus rearrangements, were detected in SCID and OS-derived T-lineage cells, consistent with a pre-TCR block in T-cell development. This study compares human T-cell development of SCID vs OS patients, and elucidates important differences that help to explain the wide range of immunologic phenotypes that result from different mutations within the same gene of various patients.

    Nonacog beta pegol is a 40-kDa polyethylene glycosylated (PEGylated) human recombinant coagulation factor IX, intended for the treatment of hemophilia B. Human coagulation factors are immunogenic in animals; therefore, to evaluate the long-term toxicity of nonacog beta pegol, an immune-deficient, athymic rat (Rowett nude; Crl:NIH-Foxn1(rnu)) was used. Rats (n = 216) were given intravenous nonacog beta pegol 0, 40, 150, 600, or 1,200 IU/kg every 5th day for 26 weeks. To avoid infections, the animals were housed in a full-barrier environment with sterilized food and bedding. Standard toxicity end points were unaffected by treatment. All treated animals were exposed to nonacog beta pegol throughout the study, and no animals developed antidrug antibodies. Immunohistochemical staining revealed PEG in choroid plexus epithelial cells in a dose-dependent manner. Transmission electron microscopy showed that PEG was distributed in cytoplasmic vesicles of these cells, with no apparent effect on cellular organelle structures. Fourteen (6.5%) animals were euthanized or died prematurely due to nontreatment-related infections in the urogenital system and skin. In conclusion, the athymic rat is a suitable model for testing chronic toxicity of human proteins that are immunogenic in animals. Nonacog beta pegol was generally well tolerated, with no adverse effect of PEG on choroid plexus epithelial cells. PMID:26940713

    ABSTRACT Despite the identification of horseshoe bats as the reservoir of severe acute respiratory syndrome (SARS)-related coronaviruses (SARSr-CoVs), the origin of SARS-CoV ORF8, which contains the 29-nucleotide signature deletion among human strains, remains obscure. Although two SARS-related Rhinolophus sinicus bat CoVs (SARSr-Rs-BatCoVs) previously detected in Chinese horseshoe bats (Rhinolophus sinicus) in Yunnan, RsSHC014 and Rs3367, possessed 95% genome identities to human and civet SARSr-CoVs, their ORF8 protein exhibited only 32.2 to 33% amino acid identities to that of human/civet SARSr-CoVs. To elucidate the origin of SARS-CoV ORF8, we sampled 348 bats of various species in Yunnan, among which diverse alphacoronaviruses and betacoronaviruses, including potentially novel CoVs, were identified, with some showing potential interspecies transmission. The genomes of two betacoronaviruses, SARSr-Rf-BatCoV YNLF_31C and YNLF_34C, from greater horseshoe bats (Rhinolophus ferrumequinum), possessed 93% nucleotide identities to human/civet SARSr-CoV genomes. Although these two betacoronaviruses displayed lower similarities than SARSr-Rs-BatCoV RsSHC014 and Rs3367 in S protein to civet SARSr-CoVs, their ORF8 proteins demonstrated exceptionally high (80.4 to 81.3%) amino acid identities to that of human/civet SARSr-CoVs, compared to SARSr-BatCoVs from other horseshoe bats (23.2 to 37.3%). Potential recombination events were identified around ORF8 between SARSr-Rf-BatCoVs and SARSr-Rs-BatCoVs, leading to the generation of civet SARSr-CoVs. The expression of ORF8 subgenomic mRNA suggested that the ORF8 protein may be functional in SARSr-Rf-BatCoVs. The high Ka/Ks ratio among human SARS-CoVs compared to that among SARSr-BatCoVs supported that ORF8 is under strong positive selection during animal-to-human transmission. Molecular clock analysis using ORF1ab showed that SARSr-Rf-BatCoV YNLF_31C and YNLF_34C diverged from civet/human SARSr-CoVs in approximately 1990. SARS

    A recent addition to the lymphokine network is human IL-10 (hIL-10). This novel lymphokine has striking homology to BCRF1 protein, the product of a previously uncharacterized open-reading frame in the Epstein-Barr virus (EBV) genome. To date, IL-10 expression has been described in several T clones induced with anti-CD3 and phorbol myristate acetate (PMA), in monocytes stimulated with lipopolysaccharide (LPS), and in murine B-cell lymphomas. We sought to determine whether human B cells express hIL-10 and, if so, its relationship to EBV and to other B-cell lymphokines. We studied 21 EBV-positive B-cell lines derived from patients with acquired immunodeficiency syndrome (AIDS) and Burkitt's lymphoma (n = 6), American Burkitt's (n = 3), African Burkitt's (n = 5), and normal lymphoblastoid cell lines (n = 7), in comparison with seven EBV-negative cell lines. All cell lines were activated with the tumor promoters PMA and teleocidin and were studied by Northern blot analysis, reverse transcription-polymerase chain reaction (RT-PCR), and enzyme-linked immunoadsorbent assay (ELISA). We demonstrated that EBV-positive cell lines derived from patients with American Burkitt's lymphoma, and especially those from patients with AIDS, constitutively express large quantities of hIL-10 by Northern blot analysis and ELISA (range, 3,101 to 25,915 pg/mL), and that both teleocidin and PMA induce hIL-10 in these cell lines. In contrast, six of seven EBV-negative cell lines did not express hIL-10 even by RT-PCR, and hIL-10 was not triggered by PMA or teleocidin. To assure that the 350 bp amplified by PCR was hIL-10 and not BCRF1, we used PCR primers, which do not amplify a fragment from plasmid templates containing BCRF1. Cloning and sequencing of the 350 bp product also demonstrated that B-cell IL-10 is identical to hIL-10 from the T-cell clone B21. Correlation of hIL-10 with other B-cell lymphokines secreted by these B-cell lines demonstrated that hIL-10 secretor cell lines also

    Peripheral blood leukocytes (PBL) from 18 homosexual men who did not have acquired immunodeficiency syndrome (AIDS) and from 9 heterosexual men were repetitively tested for their ability to generate HLA self-restricted cytotoxic T lymphocyte responses to influenza virus (flu-self) over a 2-yr period. The sera of the same donors were tested for antibodies to human T lymphotropic virus-III (HTLV-III). Six of the homosexual and none of the heterosexual donors consistently generated weak cytotoxic T lymphocyte responses to flu-self. Seven of the homosexual and none of the heterosexual donors were seropositive for antibodies to HTLV-III. No obvious correlation was detected between weak flu-self cytotoxic T lymphocyte responses and antibodies to HTLV-III. However, one homosexual donor generated no detectable cytotoxic T lymphocyte activity to flu-self, although he was a strong responder to HLA-alloantigens. This donor had an OKT4:OKT8 ratio of 0.4 and was seropositive for HTLV-III antigens; HTLV-III virus was identified in his PBL; and he developed AIDS during the course of this study. A second donor with lymphadenopathy and who was seropositive for HTLV-III antigens exhibited marginal cytotoxic T lymphocyte activity to flu-self which he subsequently lost. PBL from two patients, one with Kaposi's sarcoma and one with generalized lymphadenopathy, were also tested for cytotoxic T lymphocyte responses to flu-self and to alloantigens. Both donors failed to generate cytotoxic T lymphocyte to flu-self, but generated strong cytotoxic T lymphocyte responses to alloantigens. The selective loss of an HLA-restricted cytotoxic T lymphocyte response without loss of HLA alloantigenic cytotoxic T lymphocyte activity may be an important functional immunologic characteristic in the development of AIDS.

    Analyses of arthropod genomes have shown that the genes in the different innate humoral immune responses are conserved. These genes encode proteins that are involved in immune signalling pathways that recognize pathogens and activate immune responses. These immune responses include phagocytosis, encapsulation of the pathogen and production of effector molecules for pathogen elimination. So far, most studies have focused on insects leaving other major arthropod groups largely unexplored. Here, we annotate the immune-related genes of six arachnid genomes and present evidence for a conserved pattern of some immune genes, but also evolutionary changes in the arachnid immune system. Specifically, our results suggest that the family of recognition molecules of beta-1,3-glucanase-related proteins (βGRPs) and the genes from the immune deficiency (IMD) signalling pathway have been lost in a common ancestor of arachnids. These findings are consistent with previous work suggesting that the humoral immune effector proteins are constitutively produced in arachnids in contrast to insects, where these have to be induced. Further functional studies are needed to verify this. We further show that the full haemolymph clotting cascade found in the horseshoe crab is retrieved in most arachnid genomes. Tetranychus lacks at least one major component, although it is possible that this cascade could still function through recruitment of a different protein. The gel-forming protein in horseshoe crabs, coagulogen, was not recovered in any of the arachnid genomes; however, it is possible that the arachnid clot consists of a related protein, spätzle, that is present in all of the genomes.

    Although severe combined immune deficiency (SCID) is a very important research model for mice and SCID mice are widely used, there are only few reports describing the SCID pig models. Therefore, additional research in this area is needed. In this study, we describe the generation of Recombination activating gene-1 (Rag-1)-deficient neonatal piglets in Duroc breed using somatic cell nuclear transfer (SCNT) with gene targeting and analysis using fluorescence-activated cell sorting (FACS) and histology. We constructed porcine Rag-1 gene targeting vectors for the Exon 2 region and obtained heterozygous/homozygous Rag-1 knockout cell colonies using SCNT. We generated two Rag-1-deficient neonatal piglets and compared them with wild-type neonatal piglets. FACS analysis showed that Rag-1 disruption causes a lack of Immunoglobulin M-positive B cells and CD3-positive T cells in peripheral blood mononuclear cells. Consistent with FACS analysis, histological analysis revealed structural defects and an absence of mature lymphocytes in the spleen, mesenteric lymph node (MLNs), and thymus in Rag-1-deficient piglets. These results confirm that Rag-1 is necessary for the generation of lymphocytes in pigs, and Rag-1-deficient piglets exhibit a T and B cell deficient SCID (T-B-SCID) phenotype similar to that of rodents and humans. The T-B-SCID pigs with Rag-1 deficiency generated in this study could be a suitably versatile model for laboratory, translational, and biomedical research, including the development of a humanized model and assessment of pluripotent stem cells.

    The increasing number of cancer survivors the past decades, has sparked the need for fertility preservation strategies. Due to predominantly ethical constraints, human research material is scarce. A bovine in vitro model is a valuable alternative. Therefore, the following objectives were defined: 1) to xeno-graft bovine ovarian cortex tissue in immune deficient mice as a study-model for female fertility preservation strategies; 2) to stereologically quantify vascularization in Vascular Endothelial Growth Factor (VEGF)-treated and non-treated tissue; 3) to study preantral follicular survival in situ, after xenotransplantation. Bovine ovarian tissue strips were incubated with or without VEGF prior to grafting into female, neutered BALB/c-nu mice (n=16). Non-transplanted cortical tissue was used as a control. At time zero (control), two (2 weeks) and four (4 weeks) weeks after transplantation, grafts were retrieved and assessed by von Willebrand Factor and caspase-3 immunostaining. Data were analyzed using a linear mixed model. In the VEGF+ grafts, 31% of the follicles were considered 'alive' 2 weeks after transplantation, compared to only 17% in the VEGF- grafts (P<0.05). However, no difference could be detected 4 weeks after transplantation (P=0.76) with less follicles being considered 'alive' after transplantation (22%), compared to the control (47.5%) (P<0.05). Finally, the vascular surface density was significantly less in the grafts, irrespective of the transplantation period or the use of VEGF. Although the transplantation process overall negatively influenced the number of viable follicles and vascular density, VEGF exposure prior to transplantation can favor follicle survival during a 2 weeks transplantation period.

    We describe a 65-year-old Thai woman who developed cytomegalovirus retinitis (CMVR) in the setting of Good syndrome-a rare, acquired partial immune deficiency caused by thymoma. The patient subsequently developed vitritis with cystoid macular edema (CME) similar to immune recovery uveitis (IRU) despite control of the retinitis with antiviral agents. A comprehensive review of the literature through December, 2014, identified an additional 279 eyes of 208 patients with CMVR in the absence of human immunodeficiency virus (HIV) infection. Including our newly reported case, 9 of the 208 patients (4.3 %) had Good syndrome. Twenty-one of the 208 patients (10.1 %) had CMVR related to intraocular or periocular corticosteroid administration. The remaining 178 patients (85.6 %) acquired CMVR from other causes. Within the subset of patients who did not have Good syndrome or did not acquire CMVR followed by intraocular or periocular corticosteroid administration, there were many other factors contributing to a decline in immune function. The most common included age over 60 years (33.1 %), an underlying malignancy (28.7 %), a systemic autoimmune disorder requiring systemic immunosuppression (19.1 %), organ (15.2 %) or bone marrow (16.3 %) transplantation requiring systemic immunosuppression, and diabetes mellitus (6.1 %). Only 4.5 % of the patients had no identifiable contributor to a decline in immune function. While the clinical features of CMVR are generally similar in HIV-negative and HIV-positive patients, the rates of moderate to severe intraocular inflammation and of occlusive retinal vasculitis appear to be higher in HIV-negative patients.

Data on the immunologic consequences of folic acid, protein and iron deficiencies were reviewed in the medical literature. Investigations are difficult because of the patients' poor general condition. Results are difficult to interpret as many etiologic factors are often combined and mechanisms of immunologic responses are complex. Attention is drawn to the danger of iron therapy in patients with transferrin deficiency. PMID:6297076

    Objectives To describe the time course of recovery of walking function and other activities of daily living in patients with intensive care unit (ICU)-acquired muscle weakness. Design This is a cohort study. Participants We included critically ill patients with ICU-acquired muscle weakness. Setting Post-acute ICU and rehabilitation units in Germany. Measures We measured walking function, muscle strength, activities in daily living, motor and cognitive function. Results We recruited 150 patients (30% female) who fulfilled our inclusion and exclusion criteria. The primary outcome recovery of walking function was achieved after a median of 28.5 days (IQR=45) after rehabilitation onset and after a median of 81.5 days (IQR=64) after onset of illness. Our final multivariate model for recovery of walking function included two clinical variables from baseline: the Functional Status Score ICU (adjusted HR=1.07 (95% CI 1.03 to 1.12) and the ability to reach forward in cm (adjusted HR=1.02 (95% CI 1.00 to 1.04). All secondary outcomes but not pain improved significantly in the first 8 weeks after study onset. Conclusions We found good recovery of walking function for most patients and described the recovery of walking function of people with ICU-acquired muscle weakness.

    Good's syndrome is a relatively rare immunodeficiency condition that presents in the fourth or fifth decade of life and is defined by hypogammaglobulinemia in the setting of a thymoma. The humoral defect may be severe enough to cause an absence in B cells, with a consequent recurrence of sinopulmonary disease, chronic non-infectious diarrhea and opportunistic infections. The prognosis in patients with Good's syndrome appears to be worse than in those with X-linked agammaglobulinemia (XLA) and common variable immune deficiency (CVID). There have only been three cases of Good's syndrome associated with mycobacterium, and only one case with a cavitary lesion in the lungs. We present here a unique case of Good's syndrome with a non-mycobacterial cavitary lesion. PMID:25287948

    Objectives Coenzyme Q10 (CoQ10) deficiency syndrome is a rare condition that causes mitochondrial dysfunction and includes a variety of clinical presentations as encephalomyopathy, ataxia and renal failure. First, we sought to set up what all have in common, and then investigate why CoQ10 supplementation reverses the bioenergetics alterations in cultured cells but not all the cellular phenotypes. Design Modelling study This work models the transcriptome of human CoQ10 deficiency syndrome in primary fibroblast from patients and study the genetic response to CoQ10 treatment in these cells. Setting Four hospitals and medical centres from Spain, Italy and the USA, and two research laboratories from Spain and the USA. Participants Primary cells were collected from patients in the above centres. Measurements We characterised by microarray analysis the expression profile of fibroblasts from seven CoQ10-deficient patients (three had primary deficiency and four had a secondary form) and aged-matched controls, before and after CoQ10 supplementation. Results were validated by Q-RT-PCR. The profile of DNA (CpG) methylation was evaluated for a subset of gene with displayed altered expression. Results CoQ10-deficient fibroblasts (independently from the aetiology) showed a common transcriptomic profile that promotes cell survival by activating cell cycle and growth, cell stress responses and inhibiting cell death and immune responses. Energy production was supported mainly by glycolysis while CoQ10 supplementation restored oxidative phosphorylation. Expression of genes involved in cell death pathways was partially restored by treatment, while genes involved in differentiation, cell cycle and growth were not affected. Stably demethylated genes were unaffected by treatment whereas we observed restored gene expression in either non-methylated genes or those with an unchanged methylation pattern. Conclusions CoQ10 deficiency induces a specific transcriptomic profile that promotes

    In vivo magnetic resonance spectroscopy (MRS), a non-destructive biochemical tool for investigating live organisms, has yet to be used in the fruit fly Drosophila melanogaster, a useful model organism for investigating genetics and physiology. We developed and implemented a high-resolution magic-angle-spinning (HRMAS) MRS method to investigate live Drosophila at 14.1 T. We demonstrated, for the first time, the feasibility of using HRMAS MRS for molecular characterization of Drosophila with a conventional MR spectrometer equipped with an HRMAS probe. We showed that the metabolic HRMAS MRS profiles of injured, aged wild-type (wt) flies and of immune deficient (imd) flies were more similar to chico flies mutated at the chico gene in the insulin signaling pathway, which is analogous to insulin receptor substrate 1–4 (IRS1–4) in mammals and less to those of adipokinetic hormone receptor (akhr) mutant flies, which have an obese phenotype. We thus provide evidence for the hypothesis that trauma in aging and in innate immune-deficiency is linked to insulin signaling. This link may explain the mitochondrial dysfunction that accompanies insulin resistance and muscle wasting that occurs in trauma, aging and immune system deficiencies, leading to higher susceptibility to infection. Our approach advances the development of novel in vivo non-destructive research approaches in Drosophila, suggests biomarkers for investigation of biomedical paradigms, and thus may contribute to novel therapeutic development.

    This review focuses on the acquired causes, diagnosis, and treatment of intestinal malabsorption. Intestinal absorption is a complex process that depends on many variables, including the digestion of nutrients within the intestinal lumen, the absorptive surface of the small intestine, the membrane transport systems, and the epithelial absorptive enzymes. Acquired causes of malabsorption are classified by focussing on the three phases of digestion and absorption: 1) luminal/digestive phase, 2) mucosal/absorptive phase, and 3) transport phase. Most acquired diseases affect the luminal/digestive phase. These include short bowel syndrome, extensive small bowel inflammation, motility disorders, and deficiencies of digestive enzymes or bile salts. Diagnosis depends on symptoms, physical examination, and blood and stool tests. There is no gold standard for the diagnosis of malabsorption. Further testing should be based on the specific clinical context and the suspected underlying disease. Therapy is directed at nutritional support by enteral or parenteral feeding and screening for and supplementation of deficiencies in vitamins and minerals. Early enteral feeding is important for intestinal adaptation in short bowel syndrome. Medicinal treatment options for diarrhoea in malabsorption include loperamide, codeine, cholestyramine, or antibiotics. PMID:27086886

    Percutaneous continuous-flow (CF) micro axial blood pumps, like the Impella 5.0, are commonly used for short-term (ST) mechanical circulatory support in patients with acute decompensated heart failure. The Impella device often serves as a bridge to implantation of a long-term (LT) CF left ventricular assist device (CF-LVAD), such as the centrifugal-flow HeartWare (HVAD). All patients supported with axial CF-LVADs develop acquired von Willebrand syndrome (AVWS) as a result of mechanical shear stress. Increased shear stress leads to excessive proteolysis of von Willebrand factor and loss of high molecular weight multimers, thus contributing to platelet dysfunction and increased gastrointestinal bleeding. Bleeding events associated with AVWS have been reported in patients supported with LT CF-LVADs; however, the relation between early perioperative bleeding complications and AVWS remains poorly characterized in ST CF-LVADs. We sought to describe the relation between the development of AVWS and excessive intraoperative bleeding in a patient who was sequentially bridged with an ST micro axial device to a LT centrifugal CF-LVAD. This case highlights the importance of monitoring these hemostatic changes when bridging to LT CF-LVADs. PMID:24614358

    Features of Miller-Dieker syndrome (MDS, 17p13.3 deletion syndrome, LIS1-associated lissencephaly) include classic lissencephaly, microcephaly, cardiac malformations, growth restriction, and characteristic facial changes. Individuals with 22q11.2 deletion syndrome (DiGeorge syndrome or velocardiofacial syndrome) are known to have congenital cardiac malformations (in particular conotruncal defects), palatal abnormalities (especially velopharyngeal insufficiency), hypocalcemia, immune deficiency, learning disabilities, and characteristic facial features. This case report describes phenotypic characteristics of a patient with extremely rare instance of having both MDS and 22q11.2 deletion syndrome that is unique in the medical literature. Prognosis in this concurrent phenotype is poor with our patient suffering from several malformations seen in both conditions and expiring in the neonatal period. PMID:27617133

    2016-03-01

    The developmental disorder Rubinstein-Taybi syndrome (RTS) is frequently complicated by recurrent respiratory infections. In many cases this is likely to be the result of microaspiration or gastro-oesophageal reflux but, in a proportion, underlying antibody deficiency is a potentially modifiable susceptibility factor for infection. Relatively subtle, specific defects of pneumococcal antibody production have previously been described in the context of RTS. Here, we report a rare association between the syndrome and an overt, major primary antibody deficiency disorder (common variable immune deficiency) which was successfully managed with immunoglobulin replacement therapy. Early recognition and investigation for antibody deficiency associated with RTS allied to effective and optimized treatment are essential to minimize morbidity and mortality and improve quality and duration of life.

    1988-05-13

    As of March 21, 1988, 136 countries or territories throughout the world had reported a total of 84,256 cases of AIDS to the Global Programme on AIDS (GPA) (formerly the Special Programme on AIDS) of the World Health Organization (WHO). 37 countries or territories had reported no AIDS cases. Reports are based on either the Centers for Disease Control (CDC)/WHO surveillance definition, the WHO clinical definition, or a physician's diagnosis. From 1979 through March 21, 1988, the number of AIDS cases increased markedly in all geographic regions. The cumulative world total increased from 11,965 in 1984 to 25,150 in 1985 (a 11% increase) and to 48,413 in 1986 (a 92% increase). Because of reporting lags, the global total of AIDS cases reported for 1987 is not yet complete; however, as of March 21, 1988, 34,913 cases had been reported for 1987 (a 72% increase). Data on the distribution of AIDS cases by region are presented, followed by a discussion of the findings. Regions include: Americas, Europe, Africa, Oceania, Asia, and eastern Mediterranean countries. Epidemiologic studies indicate 3 broad yet distinct geographic patterns of transmission. Pattern I is typical of industrialized countries with large numbers of reported AIDS cases, such as North America, Western Europe, Australia, New Zealand, and parts of Latin America. In these areas, most cases occur among homosexual or bisexual males and urban intravenous (IV) drug users. Pattern II is observed in areas of central, eastern, and southern Africa and in some Carribean countries. In these areas, most cases occur among heterosexuals. Pattern III is found in areas of Eastern Europe, the Middle East, Asia, and most of the Pacific. Only small numbers of cases have been reported in these areas. PMID:3129644

    Introduction Extranodal non-Hodgkin lymphomas (NHLs) are commonly described in patients with acquired immunodeficiency syndrome (AIDS) and are related with an atypical morphology and aggressive clinical course. AIDS-associated lymphomas are characterized by their rapid progression, frequent extranodal manifestations, and poor outcome. Objective The aim of this article is to remake the clinical features of head and neck (HN) NHL in patients with AIDS to facilitate early diagnosis and treatment. Methods We evaluated the epidemiologic, clinical, immunologic, virologic, and histopathologic characteristics of 24 patients with human immunodeficiency virus (HIV)/AIDS with primary HN NHL treated at a single institution between 2002 and 2012. Histopathologic diagnosis was made according to the criteria of the World Health Organization Classification of Tumors of Hematopoietic and Lymphoid Tissues. Additional immunohistochemical stains were applied in all cases. Results Eighteen patients (75%) were men and the median of age was 39 years. The gingiva and the hard palate were the most common sites of the lesions (15 patients, 62.5%). Lactate dehydrogenase levels were elevated in 16 cases (84%). Bone marrow infiltration was detected only in 4 cases (16.6%). The median CD4 T-cell count was 100 cells/µL. According to the histopathologic evaluation, the most common subtype was diffuse large B-cell lymphoma (12 cases, 50%), followed by plasmablastic lymphoma (9 cases, 37.5%) and Burkitt lymphoma (3 cases, 12.5%). Conclusion HN NHL is a severe complication of advanced HIV/AIDS disease. Early diagnosis followed by chemotherapy plus highly active antiretroviral treatment is necessary to improve the prognosis and the survival of these patients. PMID:25992103

    Background. Histoplasmosis-associated hemophagocytic lymphohistiocytosis (HLH) is a relatively rare disorder for which data are limited regarding optimal treatment and clinical outcomes in adults. We describe the clinical features, treatment, and outcomes of patients with histoplasmosis-associated HLH at our institution. Methods. We performed a retrospective chart review of all inpatients at Parkland Hospital diagnosed with HLH associated with Histoplasma capsulatum from 2003 to 2013. Results. Eleven cases of histoplasmosis-associated HLH over this time period were identified. Nine of eleven cases were males (82%). Nine of these patients had human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS), 1 was a renal transplant patient on immunosuppressants, and the other had no documented immunocompromise. The most common HLH criteria were splenomegaly (n = 10), fever (n = 10), and ferritin >500 ng/dL (n = 9). Urine Histoplasma antigen was positive in every patient tested (n = 9 of 9), and most antibodies for Histoplasma were positive if checked (n = 4 of 5). A majority of patients received liposomal amphotericin B (n = 9) with an average treatment duration of 11 days, and 5 patients also received prednisone, intravenous immunoglobulin (IVIG), or both. Overall, 5 patients died within 30 days (45.5%), and 7 patients died within 90 days (63.6%). Of the 5 patients that received immunosuppression, 4 died (80%), whereas in the group not given additional immunosuppression (n = 5), 2 died (40%). Conclusions. Histoplasmosis-associated HLH among adults is a lethal disease of highly immunocompromised patients, especially patients with HIV/AIDS. Clinical features such as splenomegaly, elevated ferritin, and cytopenias should prompt evaluation for HLH in this population. Further data are needed to define the role of immunosuppression, IVIG, and highly active antiretroviral therapy in treating this condition. PMID:26380347

    Patient 6 - year- old boy, with history of recurrent otitis, cleft palate, was admitted to the hospital for fever, abdominal pain; He had high ESR,CRP, low T lymphocytes, VSD. Peritoneal fluid was positive for pseudomona aeroginoza. Diagnosis of DiGeorge syndrome was confirmed by further genetical study. Immune deficiencies should be considered when infections are severe, persistent resistant to standard treatment, or caused by opportunistic organisms. Treatments can often correct many of the critical and immediate problems associated with DiGeorge syndrome such as heart defects, calcium defects, poor immune system functions and cleft palate. People who had poor immune function as children due to small or missing thymus, may have an increased risk of autoimmune disorders, such as a rheumatoid arthritis and Graves disease. Because DiGeorge syndrome can result in so many disorders, a number of specialists should be involved in diagnosing specific conditions, recommending treatments and providing care. PMID:21617283

    Good's syndrome and common variable immune deficiency (CVID) are associated with chronic rhinosinusitis. Good's syndrome is characterized by hypogammaglobulinemia, B-cell depletion, variable defects in cellular immunity and thymoma. Immunodeficiency and recurrent infections can initially present after thymectomy. The pathogenesis can involve cytokines from bone marrow along with genetic defects. Intravenous gamma globulin (IVIG) restores defective signaling and can reestablish immune homeostasis. IVIG at regular intervals is the most effective way to improve the clinical symptoms and reduce patient mortality. Increased awareness of the clinical and immunological profile of this syndrome may increase its early recognition. CVID patients have hypogammaglobulinemia, respond to IVIG and have a dysregulated antimicrobial peptide response to pathogenic bacteria in the upper respiratory tract. This article reviewed selected literature on Good's syndrome, described an unusual case of Good's syndrome, CVID including SAD related to chronic rhinosinusitis. PMID:24682771

    High-grade B-cell-type non-Hodgkin's lymphomas are observed in 5% to 8% of patients positive for the human immunodeficiency virus. Nearly all cases belong to one of the three major histologic types: centroblastic or large noncleaved cell, immunoblastic and Burkitt's lymphoma, or small noncleaved cell. Some cases that are polymorphic are termed high-grade B-cell, not otherwise specified (NOS). The authors determined the immunophenotype of each histologic category of acquired immunodeficiency syndrome (AIDS)-related non-Hodgkins' lymphoma and sought a relationship with the presence of the Epstein-Barr virus (EBV). B-cell differentiation antigens, activation marker expression (human leukocyte antigen-DR, CD10, CD19, CD20, CD21, CD22, CD23, CD25, CD30, CD38), and epithelial membrane antigen were analyzed. The clonality was determined by the detection of cytoplasmic immunoglobulin, surface immunoglobulin, and the analysis of joining region (JH) immunoglobulin gene configuration by Southern blot. Epstein-Barr virus was detected either by Southern blot analysis using BamHI W probe fragment or by in situ hybridization with EBV-encoded RNA transcripts-1 specific probe. The immunophenotypic and genotypic results were compared with the morphology results and with the presence or absence of EBV. Burkitt's lymphomas were associated with EBV in 50% of cases, were monoclonal, and expressed mostly immunoglobulin (Ig) MK, CD10, CD19, CD20, CD22, and CD38. This immunophenotypic profile closely resembled those of the centroblastic cases (large noncleaved cell), in which EBV was absent. Epstein-Barr virus was associated with 90% of immunoblastic cases, and only CD10, CD20, and CD38 were expressed. CD71 was expressed in all categories of non-Hodgkin's lymphoma, and CD21 and CD23 were rarely expressed. Two cases of immunoblastic lymphoma and one case of high-grade B-NOS were polyclonal regarding JH rearrangement, but EBV tested with 1.9-Kb Xhol fragment was clonal. No significant

Community-acquired pneumonia is considered in a broad sense, without excluding certain variants that, in recent years, a number of authors have managed to delineate, such as healthcare-associated pneumonia. The latter form is nothing more than the same disease that affects more frail patients, with a greater number of risk factors, both sharing an overall common approach. PMID:26186969

    2002-02-01

    Acquired von Willebrand disease (AvWD) is a relatively rare acquired bleeding disorder that usually occurs in elderly patients, in whom its recognition may be delayed. Patients usually present predominantly with mucocutaneous bleeding, with no previous history of bleeding abnormalities and no clinically meaningful family history. Various underlying diseases have been associated with AvWD, most commonly hematoproliferative disorders, including monoclonal gammopathies, lymphoproliferative disorders, and myeloproliferative disorders. The pathogenesis of AvWD remains incompletely understood but includes autoantibodies directed against the von Willebrand factor (vWF), leading to a more rapid clearance from the circulation or interference with its function, adsorption of vWF by tumor cells, and nonimmunologic mechanisms of destruction. Laboratory evaluation usually reveals a pattern of prolonged bleeding time and decreased levels of vWF antigen, ristocetin cofactor activity, and factor VIII coagulant activity consistent with a diagnosis of vWD. Acquired vWD is distinguished from the congenital form by age at presentation, absence of a personal and family history of bleeding disorders, and, often, presence of a hematoproliferative or autoimmune disorder. The severity of the bleeding varies considerably among patients. Therapeutic options include desmopressin and certain factor VIII concentrates that also contain vWF. Successful treatment of the associated illness can reverse the clinical and laboratory manifestations. Intravenous immunoglobulins have also shown some efficacy in the management of AvWD, especially cases associated with monoclonal gammopathies. Awareness of AvWD is essential for diagnosis and appropriate management. PMID:11838652

    Synopsis Since the histological description of the hamartomatous polyp in 1957 by Horrilleno et al., several different syndromes have been described with the propensity to develop these polyps in the upper and lower GI tracts. These include Juvenile Polyposis, Peutz-Jeghers syndrome, hereditary mixed polyposis syndrome, and the PTEN hamartoma tumor syndromes (Cowden and Bannayan-Riley-Ruvalcaba syndromes), which are autosomal-dominantly inherited, and Cronkhite-Canada syndrome, which is acquired. The clinical aspects, the molecular pathogenesis, the organ systems affected, the risks of cancer, and the management of these hamartomatous polyposis syndromes will be reviewed in this paper. Although the incidence of these syndromes is low, it is important for clinicians to recognize these disorders in order to prevent morbidity and mortality in these patients, and to perform presymptomatic testing in patients at risk.

The management of acquired scalp alopecia is also reviewed including newer, promising therapies. More specific agents targeting components of the androgen system will make the treatment of androgenetic alopecia more rewarding. Similarly new immunomodulatory therapies show great promise for the lymphocyte-associated alopecias and include a new generation of macrolide immunosuppressives (tacrolimus, SDZ ASM 981, and SDZ 281-240), some of which appear to have good transcutaneous absorption.

    Introduction We compared features of nerve enlargement in inherited and acquired demyelinating neuropathies using ultrasound. Methods We measured median and ulnar nerve cross-sectional areas in proximal and distal regions in 128 children and adults with inherited (Charcot-Marie Tooth-1 (CMT-1) (n=35)) and acquired (Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) (n=55), Guillaine-Barre Syndrome (GBS) (n=21) and Multifocal Motor Neuropathy (MMN) (n=17)) demyelinating neuropathies. We classified nerve enlargement by degree and number of regions affected. We defined patterns of nerve enlargement as: none- no enlargement; mild-nerves enlarged but never more than twice normal; regional- nerves normal at at least one region and enlarged more than twice normal at atleast one region; diffuse- nerves enlarged at all four regions with atleast one region more than twice normal size. Results Nerve enlargement was commonly diffuse (89%) and generally more than twice normal size in CMT-1, but not (p<0.001) in acquired disorders which mostly had either no, mild or regional nerve enlargement (CIDP (64%), GBS (95%), and MMN (100%)). In CIDP, subjects treated within three months of disease onset had less nerve enlargement than those treated later. Discussion Ultrasound identified patterns of diffuse nerve enlargement can be used to screen patients suspected of having CMT-1. Normal, mildly, or regionally enlarged nerves in demyelinating polyneuropathy suggests an acquired etiology. Early treatment in CIDP may impede nerve enlargement. PMID:24101129

    Community-acquired Acinetobacter meningitis in adults is an extremely rare infection of the central nervous system (CNS). Here we report one adult case of this rare CNS infection and review the clinical data of another seven cases reported in the English language literature. In total, eight patients (six men and two women) aged between 19 and 63 years were studied. The causative pathogen in our patient was Acinetobacter baumannii; in the other reported cases they were most likely Acinetobacter Iwoffii, Acinetobacter johnsonii, Acinetobacter junii, a genomic species 3 or 6. No underlying disease was found in seven of the eight cases and six of the eight patients acquired the infections before the age of 30 years. Fever and consciousness disturbance were the most common clinical manifestations. Waterhouse-Friderichsen syndrome (WFS) was found in two cases. Unlike the Acinetobacter strains found in nosocomial infections, the strain of Acinetobacter meningitis in the community-acquired case did not show multiple antibiotic resistance. Most adult patients with community-acquired Acinetobacter meningitis can be saved by timely therapy with appropriate antibiotics before deterioration of the systemic condition and impairment of consciousness.

    Despite the remarkable advances in antibiotic therapies, diagnostic tools, prevention campaigns and intensive care, community-acquired pneumonia (CAP) is still among the primary causes of death worldwide, and there have been no significant changes in mortality in the last decades. The clinical and economic burden of CAP makes it a major public health problem, particularly for children and the elderly. This issue provides a clinical overview of CAP, focusing on epidemiology, economic burden, diagnosis, risk stratification, treatment, clinical management, and prevention. Particular attention is given to some aspects related to the clinical management of CAP, such as the microbial etiology and the available tools to achieve it, the usefulness of new and old biomarkers, and antimicrobial and other non-antibiotic adjunctive therapies. Possible scenarios in which pneumonia does not respond to treatment are also analyzed to improve clinical outcomes of CAP. PMID:21242952

    Currently, the porphyrias are classified in four main groups: congenital porphyria, acute intermittent porphyria, porphyria cutanea tarda hereditaria, and porphyria cutanea tarda symptomatica. The acquired form of porphyria (porphyria cutanea tarda symptomatica) occurs in older males and is nearly always associated with chronic alcoholism and hepatic cirrhosis. The main clinical changes are dermatological, with excessive skin fragility and photosensitivity resulting in erosions and bullae. Biochemically, high levels of uroporphyrin are found in the urine and stools. Treatment to date has been symptomatic and usually unsuccessful. A case of porphyria cutanea tarda symptomatica is presented showing dramatic improvement of both the skin lesions and porphyrin levels in urine and blood following repeated phlebotomy. Possible mechanisms of action of phlebotomy on porphyria cutanea tarda symptomatica are discussed. ImagesFig. 1Fig. 2 PMID:14341652

    ICU acquired neuromyopathy (IANM) is the most frequent neurological pathology observed in ICU. Nerve and muscle defects are merged with neuromuscular junction abnormalities. Its physiopathology is complex. The aim is probably the redistribution of nutriments and metabolism towards defense against sepsis. The main risk factors are sepsis, its severity and its duration of evolution. IANM is usually diagnosed in view of difficulties in weaning from mechanical ventilation, but electrophysiology may allow an earlier diagnosis. There is no curative therapy, but early treatment of sepsis, glycemic control as well as early physiotherapy may decrease its incidence. The outcomes of IANM are an increase in morbi-mortality and possibly long-lasting neuromuscular abnormalities as far as tetraplegia. PMID:23958176

    Introduction: Acquired erythroblastopenia (AE) is a rare clinical situation. It is characterized by the reduction of erythroid precursors in the bone marrow together with the low reticulocyte counts in the peripheral blood. Background: Main secondary causes of AE are drugs, Parvovirus B19 and other infectious reasons, lymphoid and myeloid neoplasia, autoimmune diseases, thymoma and pregnancy. The aim of this study is to assess the frequencies and clinical associations of AE via analyzing 12340 bone marrow samples in a retrospective manner. Material and method: Bone marrow aspirations which were obtained from patients who applied to Hacettepe University Hematology Clinic between 2002 and 2013, were analyzed retrospectively. Results: Thirty four erythroblastopenia cases were found. Patients ranged in age from 16 to 80 years with a median of 38 years. Fifteen patients were men (44%) and nineteen were women (56%). In these patients, detected causes of erythroblastopenia were MDS, idiopathic pure red cell aplasia (PRCA), parvovirus infection, post chemotherapy aplasia, plasma proliferative diseases, copper deficiency due to secondary amyloidosis, fever of unknown origin, hemophagocytic syndrome, enteric fever and legionella pneumonia. We found that between those reasons the most common causes of erythroblastopenia are MDS (17.7%) and idiopathic PRCA (17.7%). Discussion: As a result, erythroblastopenia in the bone marrow may be an early sign of MDS. In those AE cases possibility of being MDS must be kept in mind as it can be mistaken for PRCA. Conclusion: To conclude, in adults MDS without excess blast is one of the most common causes of erythroblastopenia in clinical practice and in case of erythroblastopenia the presence of MDS should be investigated.

    Abstract Acute acquired concomitant esotropia (AACE) is a rare, distinct subtype of esotropia. The purpose of this retrospective study was to describe the clinical characteristics and discuss the classification and etiology of AACE. Charts from 47 patients with AACE referred to our institute between October 2010 and November 2014 were reviewed. All participants underwent a complete medical history, ophthalmologic and orthoptic examinations, and brain and orbital imaging. Mean age at onset was 26.6 ± 12.2 years. Of the 18 cases with deviations ≤ 20 PD, 16 presented with diplopia at distance and fusion at near vision at the onset of deviation; differences between distance and near deviations were < 8 PD; all cases except one were treated with prism and diplopia resolved. Of the 29 cases with deviations > 20 PD, 5 were mild hypermetropic with age at onset between 5 and 19 years, 16 were myopic, and 8 were emmetropic with age at onset > 12 years; 24 were surgically treated and 5 cases remained under observation; all 24 cases achieved normal retinal correspondence or fusion or stereopsis on postoperative day 1 in synoptophore; in 23 cases diplopia or visual confusion resolved postoperatively. Of the 47 cases, brain and orbital imaging in 2 cases revealed a tumor in the cerebellopontine angle and 1 case involved spinocerebellar ataxia as revealed by genetic testing. AACE in this study was characterized by a sudden onset of concomitant nonaccommodative esotropia with diplopia or visual confusion at 5 years of age or older and the potential for normal binocular vision. We suggest that AACE can be divided into 2 subgroups consisting of patients with relatively small versus large angle deviations. Coexisting or underlying neurological diseases were infrequent in AACE. PMID:26705210

    We report a 6 year old girl with an isolated humoral immune deficiency and a unique combination of dysmorphic features. Physical findings include microcephaly, micrognathia, sickle shaped eyebrows, hypoplastic alae nasi, thenar hypoplasia, partial 4-5 syndactyly of toes, recessed great toes, anterior anus, and hypoplastic labia minora. Radiographic findings include triphalangeal thumbs and hypoplastic first metatarsals. She has postnatal growth retardation and her development is substantially slower than her twin's. Her clinical course has been complicated by recurrent sinopulmonary infections and pneumococcal bacteraemia. Laboratory evaluation revealed hypogammaglobulinaemia, absent B cells, and a 46,XX karyotype. A review of the literature and the London Dysmorphology Database did not produce any recognizable syndromes that match her constellation of findings. She may represent a unique syndrome of unknown etiology. PMID:11152140

    2007-01-01

    The purpose of this investigation was to enhance the efficiency of differential diagnosis of pneumonia and pulmonary tuberculosis. A hundred and fifty-nine adult patients were examined. These included 78 patients with pulmonary tuberculosis and 81 with community-acquired p neumonia. The clinical features of infiltrative pulmonary tuberculosis (n = 48) and mild community-acquired pneumonia (n = 51) were compared. The course of caseous pneumonia (n = 30) was compared with that of moderate and severe community-acquired pneumonia (n = 30). Significant differences in the manifestations of the intoxication and bronchopulmonary syndrome were not found in patients with community-acquired pneumonia and infiltrative pulmonary tuberculosis. Physical studies showed that in patients with community-acquired pneumonia, moist rale (54.9%) and crepitation (11.8%) were prevalent, but in those with infiltrative tuberculosis rale was absent in 60.4% of cases and the pattern of respiration was unchanged in 79.2%. Chest X-ray studies indicated that in patients with community-acquired pneumonia, lower lobar inflammatory changes were predominant in 62.8% of cases whereas in those with infiltrative pulmonary tuberculosis the process was mainly bilateral (43.8%) with the presence of destructive changes (83.3%) and bronchogenic dissemination (66.7%). In patients with caseous pneumonia, the intoxication syndrome was more significant than in those with severe community-acquired pneumonia. Chest X-ray studies demonstrated that in patients with caseous pneumonia, specific changes were bilateral with the involvement of 2 lobes or more, with destruction and bronchogenic dissemination while in those with community-acquired pneumonia, the pulmonary processes were predominantly bilateral (76.6%) at the lower lobar site (36.7%).

    Hypertrichosis is the excessive hair growth in any area of the skin surface. Acquired localized hypertrichosis may be secondary to multiple causes and there is a secondary form due to several drugs, which is usually reversible with discontinuation of the causative agent. Rivastigmine is a reversible and competitive inhibitor of acetylcholinesterase and butyrylcholinesterase used for symptomatic treatment of Alzheimer dementia and Parkinson's disease. It has an adequate safety profile and cutaneous side effects are unusual. Irritant contact dermatitis, allergic dermatitis, baboon syndrome, and cutaneous rash due to rivastigmine have been reported. We report on a Caucasian 80-year-old male with personal history of Alzheimer's disease. The patient started therapy with oral rivastigmine one month prior to clinical presentation of localized hypertrichosis on both forearms. Norgalanthamine has been shown to promote hair growth activity via the proliferation of dermal papilla. Acetylcholinesterase inhibitors can induce hair growth. PMID:27073702

    The neuromuscular junction is vulnerable to autoimmune attack both at the pre-synaptic nerve terminal and at the post-synaptic muscle membrane. Antibodies directed to the nicotinic acetylcholine receptor at the muscle surface are the cause of myasthenia gravis in the majority of cases. Myasthenia gravis is an acquired condition, characterised by weakness and fatigability of the skeletal muscles. The ocular muscles are commonly affected first, but the disease often generalises. Treatment includes symptom control and immunosuppression. The thymus gland plays an important role in the pathogenesis of myasthenia gravis and thymectomy is indicated in certain subgroups. Lambert-Eaton myasthenic syndrome is associated with antibodies directed to the voltage-gated calcium channel antibodies at the pre-synaptic nerve terminal. It is an acquired condition and, in some cases, may be paraneoplastic, often secondary to underlying small cell lung carcinoma. Clinical presentation is distinct from myasthenia gravis, with patients often first presenting with lower limb muscle fatigability and autonomic symptoms. Congenital myasthenic syndromes are inherited neuromuscular disorders due to mutations in proteins at the neuromuscular junction. Various phenotypes exist depending on the protein mutation. Treatment is directed towards symptom control and immunosuppression is not indicated. PMID:21365067

    We present two patients who acquired factor VIII antibodies in the immediate postoperative period. One patient was receiving warfarin that was temporarily discontinued but reintroduced after the procedure. Preoperatively, none gave a history of bleeding, even with past surgeries, and both had normal coagulation tests. Within days of surgery, hemorrhage with prolonged activated partial thromboplastin time, low factor VIII levels, and demonstrable factor VIII antibodies were observed. For the patient who was receiving warfarin the severe bleeding was attributed, at the beginning, only to the high international normalized ratio (INR), which resulted in a fatal delay in diagnosis and appropriate treatment. We would like to raise awareness of surgery as a precipitating cause of acquired hemophilia, which is something to be considered with unusual postoperative bleeding. This syndrome is remarkable for its abrupt onset within days of surgery, severe bleeding but potential successful outcome with combined hemostatic control with recombinant activated FVII (rFVIIa) and elimination of the antibody by immunosuppression.

    CHARGE syndrome is a variable, multiple congenital malformation syndrome. Patients with CHARGE syndrome have frequent infections that are presumed to be due to anatomical anomalies of the craniofacial region and upper airway, and cranial nerve problems resulting in swallowing difficulties and aspiration. The possible contribution of immunological abnormalities to these infections has not been systematically studied even though immune deficiencies have been described in patients with 22q11.2 deletion syndrome, a condition which shares remarkable clinical overlap with CHARGE syndrome. We assessed the frequency and nature of immune dysfunction in 24 children with genetically proven CHARGE syndrome. All patients, or their parents, completed a questionnaire on infectious history. Their immune system was extensively assessed through full blood counts, immunoglobulin levels, lymphocyte subpopulations, peripheral B- and T-cell differentiation, T-receptor excision circle (TREC) analysis, T-cell function, and vaccination responses. All CHARGE patients had a history of infections (often frequent), mainly otitis media and pneumonia, leading to frequent use of antibiotics and to hospital admissions. Decreased T-cell numbers were found in 12 (50%) patients, presumably caused by insufficient thymic output since TREC amounts were also diminished in CHARGE patients. Despite normal peripheral B-cell differentiation and immunoglobulin production in all patients, 83% of patients had insufficient antibody titers to one or more early childhood vaccinations. Based on our results, we recommend immunological evaluation of CHARGE patients with recurrent infections. PMID:26544072

  14. Diagnosis and treatment of chronic acquired demyelinating polyneuropathies.

    PubMed

    Latov, Norman

    2014-08-01

    Chronic neuropathies are operationally classified as primarily demyelinating or axonal, on the basis of electrodiagnostic or pathological criteria. Demyelinating neuropathies are further classified as hereditary or acquired-this distinction is important, because the acquired neuropathies are immune-mediated and, thus, amenable to treatment. The acquired chronic demyelinating neuropathies include chronic inflammatory demyelinating polyneuropathy (CIDP), neuropathy associated with monoclonal IgM antibodies to myelin-associated glycoprotein (MAG; anti-MAG neuropathy), multifocal motor neuropathy (MMN), and POEMS syndrome. They have characteristic--though overlapping--clinical presentations, are mediated by distinct immune mechanisms, and respond to different therapies. CIDP is the default diagnosis if the neuropathy is demyelinating and no other cause is found. Anti-MAG neuropathy is diagnosed on the basis of the presence of anti-MAG antibodies, MMN is characterized by multifocal weakness and motor conduction blocks, and POEMS syndrome is associated with IgG or IgA λ-type monoclonal gammopathy and osteosclerotic myeloma. The correct diagnosis, however, can be difficult to make in patients with atypical or overlapping presentations, or nondefinitive laboratory studies. First-line treatments include intravenous immunoglobulin (IVIg), corticosteroids or plasmapheresis for CIDP; IVIg for MMN; rituximab for anti-MAG neuropathy; and irradiation or chemotherapy for POEMS syndrome. A correct diagnosis is required for choosing the appropriate treatment, with the aim of preventing progressive neuropathy. PMID:24980070
