    The object of this study was to determine how many of the patients treated at the Pediatric Odontology Clinic, a branch of the Maxillo-Facial Surgery Service at the Veinte de Noviembre Regional Hospital, ISSSTE, are VIH-positive of show serious manifestations of Acquired Immuno-Deficiency Syndrome (AIDS). For such purpose, 100 pediatric patients suffering from different systemic or local diseases were evaluated, the most common being hematological alterations. Results evidenced the presence of VIH in the blood of five of the pediatric subjects, all suffering from Hemophilia.

    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.

    Full Text Available Background: The course of human immunodeficiency virus infection and the acquired immunodeficiency syndrome can be complicated by a variety of endocrine abnormalities, including abnormalities of thyroid gland. Materials and Methods: This study was designed to understand the spectrum of pathology of thyroid in Indian patients with AIDS. The present study describes the findings of retrospective autopsy findings of 158 patients with AIDS which revealed infectious diseases from a time period before the use of highly active antiretroviral regimen. Results: A wide range of bacterial, fungal, and viral infections were observed. Tuberculosis was recorded in 14 (09% patients, Cryptococcus neoformans in 11 (7% patients and cytomegalovirus in 3 (2% patients. Hashimoto's thyroiditis and lymphocytic thyroiditis were seen in 02 (01% patients each. One patient had dual infection comprising of tuberculosis and cytomegalovirus infection. The other microscopic findings observed were goiter (2 patients, interstitial fibrosis in thyroid (7 patients, and calcification in thyroid (8 patients. Conclusions: Abnormalities of thyroid are uncommon findings in patients with HIV infection however several case reports of thyroid involvement by infectious agents and neoplasm are described in these patients; hence patients with HIV infection should be closely followed up for development of goiter or abnormalities of thyroid functions.

    Background Cytomegalovirus (CMV) retinitis is the most severe intraocular complication that results in total retinal destruction and loss of visual acuity in patients with acquired immunodeficiency syndrome (AIDS). This study aimed to investigate the fundus characteristics, systemic manifestations and therapeutic outcomes of CMV retinitis associated with AIDS.Methods It was a retrospective case series. CMV retinitis was present in 39 eyes (25 patients). Best corrected visual acuities, anterior segment, fundus features, fundus fluorescence angiography (FFA) and CD4+ T-lymphocyte counts of the patients with CMV retinitis associated with AIDS were analyzed. Intravitreal injections of ganciclovir (400 μg) were performed in 4 eyes (2 patients).Results Retinal vasculitis, dense, full-thickness, yellow-white lesions along vascular distribution with irregular granules at the border, and hemorrhage on the retinal surface were present in 28 eyes. The vitreous was clear or mildly opaque.Late stage of the retinopathy was demonstrated in 8 eyes characterized as atrophic retina, sclerotic and attenuated vessels, retinal pigment epithelium (RPE) atrophy, and optic nerve atrophy. Retinal detachment was found in 3 eyes. The average CD4+ T-lymphocyte count in peripheral blood of the patients with CMV retinitis was (30.6±25.3) ×106/L (range,(0-85) × 106/L). After intravitreal injections of ganciclovir, visual acuity was improved and fundus lesions regressed.Conclusions CMV retinitis is the most severe and the most common intraocular complication in patients with AIDS. For the patients with yellow-white retinal lesions, hemorrhage and retinal vasculitis without clear cause, human immunodeficiency virus (HIV) serology should be performed. Routine eye examination is also indicated in HIV positive patients.

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

    Full Text Available Human immunodeficiency virus infection is the first major pandemic of the 20th century. At present, almost 10 million people are known to be infected with this virus, and it is estimated that by the year 2000, approximately 40 million people will be infected. Transmission of this deadly infection is predominantly by sexual contact. Individuals infected with this virus pass through several predictable stages with progressive decrease in circulating CD4+ T cells. During the advanced stage, these patients develop various opportunistic infections or malignancies, or both. It is this advanced stage that was first recognized as AIDS, which has a 100% mortality rate. The opportunistic organisms that can involve the eye in patients with AIDS include cytomegalovirus, herpes zoster, Toxoplasma gondii, Mycobacterium tuberculosis, Cryptococcus neoformans, Mycobacterium avium-intracellulare, Pneumocystis carinii, Histoplasma capsulatum, Candida, and others. Intraocular lesions from these agents often represent disseminated infections. Visual morbidity occurs secondary to retinitis due to cytomegalovirus, herpes zoster, or Toxoplasma gondii. Anti-viral agents such as ganciclovir or foscarnet are effective against cytomegalovirus infection. The role of the ophthalmologist in the diagnosis and management of AIDS is becoming increasingly important. Not only does the eye reflect systemic disease, but ocular involvement may often precede systemic manifestations. In the AIDS patient, the ophthalmologist thus has an opportunity to make not only a slight-saving, but also life-saving diagnosis of disseminated opportunistic infections.

    Cerebral CT scannings were performed in 19 homosexual men with the acquired immunodeficiency syndrome (AIDS). Nearly half of them (9 patients) had cortical atrophy. Three patients with toxoplasmosis had cerebral pathology, in two of them with ring enhancement while the third had an ill-defined nonspecific lesion with slight heterogeneous enhancement without ring formation. Two patients with multifocal leucoencephalopathy and non-Hodgkin's lymphoma, respectively, presented non-enhancing, low attenuating lesions at CT.

    Polymorphous hemangioendotheliomas (PH) are rare and borderline malignant tumors that are among the wide range of vascular tumors. We report here a 13-year-old male presenting with a history of weight loss, opportunistic infections, and lymphadenopathy. He was determined to be HIV positive and to have acquired immunodeficiency syndrome (AIDS). A biopsy of a femoral node was diagnostic of PH. His systemic lymphadenopathy appeared to resolve with anti-retroviral therapy. This tumor should be considered within the differential diagnoses of pediatric and immunocompromised patients.

    1987-06-01

    Four black men with the acquired immunodeficiency syndrome (AIDS) demonstrated profound alterations in hair patterns two to three years after their first symptoms appeared. The hair became longer, lighter, softer, and silky, and it was occasionally discolored. One patient was thought to be of Indian extraction. These changes may not be as apparent in nonblack persons. Possible explanations are a retrogression of hair pattern to an earlier stage of growth, a phenomenon reminiscent of, but not similar to, malnutrition trichosis, or a combination of both. Closer attention should be paid to the hair of AIDS patients. Histologic and chemical analysis may be appropriate.

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

    2014-06-01

    Full Text Available Acquired immunodeficiency syndrome (AIDS is a human immune system disease characterized by increased susceptibility to opportunistic infections, certain cancers and neurological disorders. The syndrome is caused by the human immunodeficiency virus (HIV that is transmitted through blood or blood products, sexual contact or contaminated hypodermic needles. Antiretroviral treatment reduces the mortality and the morbidity of HIV infection but is increasingly reported to be associated with increasing reports of metabolic abnormalities. The prevalence and incidence of diabetes mellitus in patients on antiretroviral therapy is high. Recently, a joint panel of American Diabetes Association (ADA and European Association for the Study of Diabetes (EASD experts updated the treatment recommendations for type 2 diabetes (T2DM in a consensus statement which provides guidance to health care providers. The ADA and EASD consensus statement concur that intervention in T2DM should be early, intensive, and uncompromisingly focused on maintaining glycemic levels as close as possible to the nondiabetic range. Intensive glucose management has been shown to reduce microvascular complications of diabetes but no significant benefits on cardiovascular diseases. Patients with diabetes have a high risk for cardiovascular disease and the treatment of diabetes should emphasize reduction of the cardiovascular factors risk. The treatment of diabetes mellitus in AIDS patients often involves polypharmacy, which increases the risk of suboptimal adherence

    Infection with the Human Immunodeficiency Virus type 1 (HIV-1) may produce a variety of central nervous system (CNS) symptoms and signs. CNS involvement in patients with the Acquired Immunodeficiency Syndrome (AIDS) includes AIDS dementia complex or HIV-1 associated cognitive/motor complex (widely known as HIV encephalopathy), progressive multifocal leucoencephalopathy (PML), opportunistic infections such as Toxoplasma gondii, TB, Cryptococcus and infiltration by non-Hodgkin`s B cell lymphoma. High resolution structural imaging investigations, either X-ray Computed Tomography (CT scan) or Magnetic Resonance Imaging (MRI) have contributed to the understanding and definition of cerebral damage caused by HIV encephalopathy. Atrophy and mainly high signal scattered white matter abnormalities are commonly seen with MRI. PML produces focal white matter high signal abnormalities due to multiple foci of demyelination. However, using structural imaging techniques there are no reliable parameters to distinguish focal lesions due to opportunistic infection (Toxoplasma gondii abscess) from neoplasm (lymphoma infiltration). It is studied the use of radionuclide brain imaging techniques in the investigation of HIV infected patients. Brain perfusion Single Photon Emission Tomography (SPET), neuroreceptor and Positron Emission Tomography (PET) studies are reviewed. Greater emphasis is put on the potential of some radiopharmaceuticals, considered to be brain tumour markers, to distinguish intracerebral lymphoma infiltration from Toxoplasma infection. SPET with {sup 201}Tl using quantification (tumour to non-tumour radioactivity ratios) appears a very promising technique to identify intracerebral lymphoma.

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

    2000-01-01

    Full Text Available The paper summarizes recent findings on the epidemiology and pathogenesis of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/Aids, highlighting the role of co-infections with major tropical diseases. Such co-infections have been studied in the Brazilian context since the beginning of the Aids epidemic and are expected to be more frequent and relevant as the Aids epidemic in Brazil proceeds towards smaller municipalities and the countryside, where tropical diseases are endemic. Unlike opportunistic diseases that affect basically the immunocompromised host, most tropical diseases, as well as tuberculosis, are pathogenic on their own, and can affect subjects with mild or no immunossuppression. In the era of highly active anti-retroviral therapies (HAART, opportunistic diseases seem to be on decrease in Brazil, where such medicines are fully available. Benefiting from HAART in terms of restoration of the immune function, putative milder clinical courses are expected in the future for most co-infections, including tropical diseases. On the other hand, from an ecological perspective, the progressive geographic diffusion of Aids makes tropical diseases and tuberculosis a renewed challenge for Brazilian researchers and practitioners dealing with HIV/Aids in the coming years.

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

    Granulocyte functions were studied in 20 patients with acquired immunodeficiency syndrome (AIDS), 20 subjects with lymphadenopathy syndrome (LAS) and 15 symptom-free drug addicts (SFDA). Polymorphonuclear leucocyte (PMNL) phagocytosis and killing of C. albicans appeared normal in homosexual men with AIDS, while drug addicts with AIDS or LAS and SFDA showed a significant defect of these functions as compared to healthy controls. Migration of PMNL in response to a chemoattractant was normal in SFDA, but markedly defective both in LAS and in AIDS patients. In the AIDS group no significant differences were evident between homosexual men and drug addicts. We conclude that defective PMNL phagocytosis and killing, unlike defective migration, are somehow related to drug abuse rather than to infection with the causative agent of the immunodeficiency.

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.

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

After clinical examination and investigations, she was diagnosed with disseminated tuberculosis (including central nervous system involvement, and Human immunodeficiency virus/acquired immune deficiency syndrome. Her hospital stay was complicated. She developed stridor and a cerebrovascular accident with left hemiplegia. She died approximately 2 weeks after admission. The potential causes of her stridor included a mediastinal mass or a central mechanism secondary to tuberculosis meningitis. Limited resources precluded definitive imaging of the chest to rule out a mediastinal mass. Further, an autopsy was not done. Despite these limitations, this case is unique because it reports the presence of both stridor and tuberculosis meningitis in an adult patient.Keywords: Human immunodeficiency virus, acquired immune deficiency syndrome, meningitis, stridor, tuberculosis

    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.

    Background Increased risk of atherosclerosis has been reported in patients with human immunodeficiency virus (HIV)infection since highly active antiretroviral therapy (HAART) has come into use. However, there is no clear evidence of premature atherosclerosis in Chinese HIV-infected patients. Our study was designed to determine the relationship between HIV infection and atherosclerosis in Chinese HIV-infected patients.Methods One hundred and forty-five patients were enrolled in this study. These included 82 HIV-infected patients (41HAART-treated and 41 antiretroviral therapy (ART) naive patients) and 43 HIV-negative control subjects. Data on traditional cardiovascular risk factors, HIV infection parameters, and treatment regimens were collected. Pulse wave velocity (PWV) was determined using a pulse pressure analyzer to evaluate the function of the arterial wall as an indicator of atherosclerotic vascular damage.Results A higher PWV ((1358.3±117.8) cm/s vs. (1270.2±189.2) cm/s, P=0.010) was found in ART na(i)ve HIV-infected patients compared with control subjects. However, HAART treated patients had lower PWV compared to ART na(i)ve patients ((1283.8±181.4) cm/s vs. (1358.0±117.8) cm/s, P=0.033). Multiple regression analysis revealed that age (B=5.218, 95% confidence interval (CI) 1.420-9.016, P=0.008), current smoking (B=-74.671, 95% CI -147.003 to -2.339, P=0.043) and HAART (92.7% patients on a protease inhibitor-free regimen) (B=-169.169, 95% CI-272.508 to -65.831, P=0.010) were associated with reduced PWV in HIV-infected patients.Conclusions Reduced PWV in HIV-infected Chinese patients indicates that they are more likely to develop arterial wall stiffness, possibly by atherosclerosis. A protease inhibitor-free regime may be protective for arterial wall of HIV infected patients.

The diagnosis of RS was based on the combination of dermatological and articular alterations. The patient's cutaneous lesions were characterized by exfoliation and the formation of crusts located on the face, scalp, genitals, hands, and feet; onychodystrophy with opacity; yellowish coloring; and hyperkeratosis of the nails. Articular lesions led to progressive deformity of phalangeal joints of the hands, and intensive arthralgia, mainly of the larger joints (shoulders, elbows, hips and knees. AIDS treatment was administered with anti-retroviral drugs (zidovudine and didanosine; for tuberculosis (isoniazid, rifampicine, and pyrazinamide; and (prednisone and inometacine for the RS. The patient recovered with the improvement of articular symptoms; however, on the eighth day of treatment, the patient showed significant hemoptysis and hypovolemic shock, and died.

    2006-01-01

    Full Text Available We report a case of cerebral meningoencephalitis due to Trypanosoma cruzi in a patient with acquired immunodeficiency syndrome. The patient presented with seizures and focal neurological signs. Definitive diagnosis of chagasic meningoencephalitis was made by demonstration of free trypomastigote forms in the cerebrospinal fluid. Benznidazol was prescribed with clinical and neurological improvement. Antiretroviral drugs improved cellular immunity and three years later the patient presents a good clinical condition with immune reconstitution and undetectable viral load. Chagasic meningoencephalitis has a poor prognosis when specific treatment is not initiated or is delayed. A high index of diagnosis is necessary for early diagnosis and treatment, especially in endemic areas for Trypanosoma cruzi infection.

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

    Full Text Available Abstract Introduction Diffuse lung infiltrates are a common finding in patients with acquired immunodeficiency syndrome and causes range from infectious processes to malignancies or interstitial lung diseases. Pulmonary alveolar proteinosis is a rare pulmonary disorder rarely reported in patients infected with human immunodeficiency virus. Secondary pulmonary alveolar proteinosis is associated with conditions involving functional impairment or reduced numbers of alveolar macrophages. It can be caused by hematologic malignancies, inhalation of toxic dust, fumes or gases, infectious or pharmacologic immunosuppression, or lysinuric protein intolerance. Case presentation A 42-year-old African American man infected with human immunodeficiency virus was admitted with chronic respiratory symptoms and diffuse pulmonary infiltrates. Chest computed tomography revealed bilateral spontaneous pneumothoraces, for which he required bilateral chest tubes. Initial laboratory investigations did not reveal any contributory conditions. Histological examination of a lung biopsy taken during video-assisted thoracoscopy showed pulmonary alveolar proteinosis concurrent with cytomegalovirus pneumonitis. After ganciclovir treatment, our patient showed radiologic and clinical improvement. Conclusion The differential diagnosis for patients with immunosuppression and lung infiltrates requires extensive investigations. As pulmonary alveolar proteinosis is rare, the diagnosis can be easily missed. Our case highlights the importance of invasive investigations and histology in the management of patients infected with human immunodeficiency virus and pulmonary disease who do not respond to empiric therapy.

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

    Full Text Available Acquired Immunodeficiency Syndrome (AIDS, a global disease, caused by the Human Immunodeficiency Virus (HIV is arguably the greatest health problem of this age and there is need to make first class information on the management of HIV/AIDS available through the use of Web-Based Technology. This paper examined the various ways of contacting HIV and the effort made by Information and Technology to make life easier for people living with the virus in Nigeria. Questionnaires were distributed to Doctors and people living with HIV/AIDS to access their knowledge and belief about the said disease. MySQL was used to generate the database, to store all the vital information about the patients, their Doctors and their complaints. PHP programming for the implementation of the interfaces, Dreamweaver HTML for the design of the web-based application, T-test and Microsoft Excel were used for the analysis of data collected. The study looked into the occupation, age range and the marital status of different categories of people living with the virus. It was discovered that there were quite large numbers of people who are living with the virus.

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

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

    Full Text Available The Centers for Disease Control currently report cervical, vulvar, vaginal, anal and some head and neck cancers as human papillomavirus (HPV-associated cancers. Only cervical cancer is listed amongst acquired immunodeficiency syndrome (AIDS defining illnesses. All of these cancers may represent progression of the immunocompromised state with the inability to eradicate viral infection. This study reports the case of a 27-year old HIV positive female presenting with a persistent right vulvar exophytic lesion. High-risk HPV analysis and immunostaining for P16 were both positive. A biopsy of the lesion revealed invasive squamous cell carcinoma. The patient underwent neoadjuvant radiation and chemotherapy followed by a radical vulvectomy. During treatment, her CD4 T-lymphocyte count decreased to 120 advancing her condition from HIV to AIDS. This case suggests that all HPV-associated cancers should be included as AIDS defining illnesses.

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

    To investigate the features of oral lesions in patients with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS). A total of 127 HIV-seropositive patients were interviewed for health information and examined for their HIV-related oral lesions according to the EC Clearing House Criteria on Oral Problems related to HIV-Infection (1992). The examinations were conducted by dental specialist and HIV specialist. The CD4 T cell count in peripheral blood of the patients was tested by flow cytometry. The patients were divided into HIV- infected group (42) and AIDS group (85) according to CDC Classification System for HIV- Infected Adults and Adolescents (revised in 1993). Chi-square test was used to test the relationship between systemic disease and oral lesions, and the difference of the prevalence of oral lesions between the two groups. Among the 127 patients, oral candidiasis (51/127), oral hairy leukoplakia (24/127) were common oral manifestation. There was no relationship between the oral manifestation and systemic disease (P = 0.397). The occurrence of oral lesions and oral candidiasis was significantly different between the two groups (χ² = 7.684, P = 0.006; χ² = 14.410, P < 0.001). The CD4 count was related to the prevalence of oral lesions (P = 0.006) and oral candidasis (P = 0.003). Most oral lesions appeared before the appearance of systemic disease. Oral candidiasis and oral hairy leukoplakia were the most common lesions.Oral lesions had no relationship with systemic disease but could be still an indicator for disease progress.

    To establish the real localization of rifabutin-related corneal deposits in a patient with human immunodeficiency virus (HIV) infection by in vivo HRT II confocal microscopy with related clinicopathologic implications. Observational case report. After Siena University Institutional Review Board approval in May 2008 and specific informed consent, a 54-year-old patient with HIV infection under rifabutin treatment for acquired immunodeficiency syndrome-related Mycobacterium avium complex prevention who developed diffuse corneal deposits was examined at the Department of Ophthalmology of Siena University. He underwent a complete clinical eye examination, biomicroscopy, and digital slit lamp photographs, endothelial specular microscopy, ultrasound pachymetry, and confocal microscopy by HRT II system. Confocal scans revealed the presence of deep stromal and pre descemetic hyperreflective polymorphous deposits. In vivo confocal examination excluded the presence of rifabutin-related deposits at endothelial level. Confocal microscopy enables establishment of the real localization of rifabutin deposits at deep stromal level, providing a better qualitative analysis of all corneal layers compared to biomicroscopic examination, with clinical and physiopathologic implications.

    Acquired Immunodeficiency Syndrome (AIDS) is one of the most critically acclaimed endemic diseases, caused by two lentiviruses HIV-1 and 2. HIV-2 displays intimate serological and antigenic resemblance to Simian Immunodeficiency Virus (SIV) along with less pathogenicity, lower infectivity and appreciable cross reactivity with HIV-1 antigens. The present era is confronted with the challenge to fabricate a vaccine effective against all clades of both the species of HIV. But vaccine development against HIV-1 has proven highly intricate, moreover the laborious and deficient conventional approaches has slackened the pace regarding the development of new vaccines. These concerns may be tackled with the development of HIV-2 vaccine as a natural control of HIV-1 that has been found in ancestors of HIV-2 i.e. African monkeys, mangabeys and macaques. Thereby, suggesting the notion of cross protection among HIV-2 and HIV-1. Assistance of bioinformatics along with vaccinomics strategy can bring about a quantum leap in this direction for surpassing the bottleneck in conventional approaches. These specifics together can add to our conception that HIV-2 vaccine design by in silico strategy will surely be a constructive approach for HIV-1 targeting.

    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.

    2001-01-01

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

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

    To assess the incidence of oral candidiasis and its influencing factors in patients with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS). An oral examination was conducted in the 1 566 HIV/AIDS patients in the Third Hospital of Kunming from March 2008 to September 2012 (M/F: 1 062/504, age range: 0.2 to 84.0 years old). The HIV viral load (HIV- RNA) and peripheral blood CD4 count were respectively analyzed by Bayer Q340 fluorescence signal surveying instrument (bDNA method) and flow cytometry analysis. The information on usage of highly active anti-retroviral (HAART) drugs and transmission of HIV were obtained through questionnaires. The incidence of oral candidiasis in patients with different HIV-RNA levels and CD4 count and the use of HAART was analyzed and compared. The total incidence of oral candidosis was 31.0% (486/1 566) and there was no difference in sex. The oral lesions were presented by three types, psudomembranous candidosis (PC), erythematous candidosis (EC) and angular cheilitis (AC), and the morbidity was 13.9% (217/1 566), 17.0% (267/1 566) and 4.9% (77/1 566), respectively. The average level of CD4 count in psudomembranous candidosis, erythematous candidosis and angular cheilitis [81.0 (146.0), 74.0 (152.0) and 69.0 (121.5) cell/µl] showed no significant difference (P > 0.05). The incidence of oral candidiasis in non-HAART and HAART subjects were 36.3% (402/1 107) and 18.3% (84/459), respectively (P = 0.000). The CD4 count and absolute counts of HIV viral load in oral candidiasis patients and non-oral candidiasis patients had significant difference (Z = -10.261, P = 0.000 and Z = -4.762, P = 0.000). The morbidity of oral candidiasis in HIV/AIDS patients in Yunnan Province was high, including PC, EC and AC and hyperplastic candidosis was not detected. The incidence was related to the degree of immune suppression and HIV viral load.

    Full Text Available Background: Indonesia’s increase of acquired immunodeficiency syndrome (AIDS cases is one of the fastest. Mortality cases of AIDS also increase per year. Central nervous system (CNS opportunistic infection is one of the most likely manifestations on advanced stage of Human immunodeficiency virus (HIV/AIDS patients. Common CNS opportunistic infections are toxoplasma infection and tuberculous meningitis (TBM. The study aimed to analyze the predictor of mortality in AIDS patients with CNS opportunistic infections. Methods: This study reviewed 151 medical records from AIDS patients with CNS opportunistic infection admitted to the Department of Neurology, Dr. Hasan Sadikin General Hospital Bandung from 2007-2012. This study was conducted from April to November 2013. Patients’ clinical manifestations (seizure, headache, altered consciousness, laboratory examination (CD4+ level count and treatment history (antiretroviral or ART and cotrimoxazole were collected. Chi-square and logistic regression test were used to determine the mortality predictor in patients. Results: Mortality rate was 37.7%. Clinical manifestations from patients were seizure 29.8%, altered consciousness 66.2%, and headache 88.7%. Patients had cotrimoxazole treatment 44.4% and 38.4% patients had ART. CD4+ level count data from 86 patients were obtained, 94% had CD4+ level count ≤200. Bivariate analysis showed altered consciousness had significant mortality predictor (Odd ratio (OR: 29.944; 95% Confidence interval (CI 6.9–129.945; p<0,0. Multivariate analysis showed ART had highest predictive mortality value (OR: 2.968; 95% CI 1.236–7.126; p=0.015. Conclusions: Altered consciousness and no antiretroviral treatment are mortality predictors in AIDS patients with CNS opportunistic infections.

    Full Text Available Abstract The coexistence of systemic lupus erythematosus (SLE in patients with congenital human immunodeficiency virus (HIV infection is rare. This is a case report of a child diagnosed with SLE at nine years of age. She initially did well on non-steroidal anti-inflammatory agents, hydroxychloroquine, and steroids. She then discontinued her anti-lupus medications and was lost to follow-up. At 13 years of age, her lupus symptoms had resolved and she presented with intermittent fevers, cachexia, myalgias, arthralgias, and respiratory symptoms. Through subsequent investigations, the patient was ultimately diagnosed with congenitally acquired immunodeficiency syndrome (AIDS.

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

    Full Text Available Erythrovirus B19 infects erythrocytic progenitors, transiently interrupting erythropoiesis. In AIDS patients it causes chronic anemia amenable to treatment. We looked for evidences of B19 infection in stored bone marrow material from patients with acquired immunodeficiency syndrome. Histological sections were made from stored paraffin blocks from 33 autopsies (39 blocks and 35 biopsies (45 blocks, 30 patients performed from 1988 to 2002. They were examined after hematoxylin-eosin (HE staining, immunohistochemical (IHC, and in situ hybridization. HE revealed intra-nuclear inclusion bodies ("lantern cells" suggesting B19 infection in 19 sections corresponding to 19 of 63 patients examined with this test. Seven of 78 sections subjected to immunohistochemistry were positive, corresponding to 7 of 58 patients examined with this test. Fourteen sections corresponding to 13 of the 20 HE and/or IHC positive patients were subjected to in situ hybridization, with six positives results. Among the 13 patients subjected to the three techniques, only one gave unequivocal positive results in all and was considered a true positive. The frequency of B19 infection (1/63 patients in the material examined can be deemed low.

    1998-12-01

    A 32-year-old man with acquired immunodeficiency syndrome (AIDS) admitted to the hospital for treatment of visceral leishmaniasis was inadvertently given 10 times the prescribed first dose of sodium stibogluconate ([Sb] 6.5 g instead of 0.65 g). He experienced no immediate major toxicity during the first 48 hours, but a significant rise of pancreatic enzyme activities was observed (amylase at 10 times the upper limit of normal, lipase at 50 times the upper limit of normal) without clinical signs or indications on computed tomography (CT) of pancreatitis. The third day after the overdose, he developed appendicitis, which appeared coincidental; he recovered uneventfully from surgery. Most of the overdose of Sb was eliminated within the first few hours. Pharmacokinetics remained linear; the rapid, long elimination half-lives (2.7 hours and 54 hours, respectively) were similar to those in previously published results. The administration of a chelating agent, dimercaptosuccinic acid (DMSA), 72 hours after the Sb overdose did not modify the pharmacokinetics of the medication.

    Eleven of 25 rhesus monkeys which died of simian acquired immunodeficiency syndrome (SAIDS) caused by infection with a type D retrovirus related to Mason-Pfizer monkey virus showed evidence of muscle weakness and atrophy and had elevated levels of muscle enzymes. Biopsies of affected muscle studied with enzyme histochemistry showed the characteristic features of polymyositis. Inflammatory cells consisting of lymphocytes, macrophages, and large vacuolated bizarre-shaped cells of undetermined type were surrounding or invading muscle fibers and were present in the perivascular spaces and endomysia septa. Within the perivascular infiltrates, lymphocytes were abundant but very few macrophages were present. Other myopathic features including profound proliferation of fibrous tissue, necrosis, and phagocytosis of muscle fibers were noted to a variable degree. The retrovirus was isolated from affected muscles. The clinical and historical features of polymyositis in rhesus monkeys with SAIDS are very similar to those of human polymyositis. The polymyositis in SAIDS induced by a type D retrovirus related to Mason-Pfizer monkey virus is an excellent primate model to study the mechanism and morphological changes of viral-induced muscle damage.

    A morphologic evaluation was carried out on adrenal glands from 128 autopsied patients with the acquired immunodeficiency syndrome (AIDS). The adrenal gland was compromised in 99.2% of the cases, with distinct pathological features and infectious agents. Inflammatory infiltrates were observed in 99.2% of the cases with a predominance of mononuclear cells in 97.4%, affecting mainly the medulla. Necrosis, fibrosis, hemorrhages and neoplasias were observed. We also described 3 (2.3%) cases of calcification located in the adrenal gland central vein (AGCV). This is seldom mentioned in the literature. Cytomegalovirus was the most frequent infectious agent, observed in 48.4% of cases. Balamuthia mandrillaris, a free living ameba, was found in one case affecting the entire gland. We also found a nest of Trypanosoma cruzi in the musculature of the AGCV. The presence of the nest of T cruzi in AGCV may play a role in the reactivation of this infection in immunosuppressed individuals. Pathologic processes and opportunistic infections may contribute to the alterations in the adrenal gland that lead to multiple organ failure observed in terminal AIDS patients.

    Computed tomography of the chest was performed on 42 occasions as part of the diagnostic work-up in 26 homosexual men with, or suspected of the acquired immunodeficiency syndrome (AIDS). In 17 cases both the chest radiographs and the lung scans were abnormal, and bronchoscopy and/or lung biopsy established an etiologic diagnosis in the majority of these cases. In 9 cases CT of the lungs revealed unequivocal interstitial infiltration in the presence of a normal chest radiography, and subsequently and etiologic agent was demonstrated in all these cases. In 9 cases, patients with symptoms indicative of pulmonary infection had both a normal chest radiograph and a normal lung scan, and in none of these cases did the clinical course or additional diagnostic procedures indicate the presence of current opportunistic lung infection. CT of the lungs seems to identify accurately those patients with severe HIV-related diseases in whom invasive diagnostic procedures such as bronchoalveolar lavage and/or lung biopsy should be done.

    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.

  14. Can we find a solution to the human immunodeficiency virus/acquired immune deficiency syndrome controversy? Is acquired immune deficiency syndrome the consequence of continuous excessive stressing of the body?

    1996-04-01

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

    To summarize the morbidity, mortality, clinical manifestations and risk factors for IRIS (immune reconstruction inflammatory syndrome) during HAART (highly active antiretroviral therapy) in China. From October 2007 to September 2009, a prospective cohort of 238 AIDS (acquired immunodeficiency syndrome) patients on HAART from Hunan and Jianxi provinces was recruited for a follow-up of 24 weeks. And 47 and 191 patients were assigned into the IRIS and non-IRIS groups respectively. The data of general information, clinical manifestations and treatment of two groups were collected and compared. Blood samples were collected in both groups at pre-and post-HAART 12 weeks, 24 weeks for HIV viral load and CD4(+) cell count examinations. A statistical analysis was performed. A total of 47 (19.7%) IRIS cases was analyzed. The median onset of IRIS was 28 (9 - 36) days. And 29 (61.7%) cases of tuberculosis IRIS were found. There was no significant difference in age, gender, route of transmission and antiretroviral regimens between the IRIS and non-IRIS groups. At baseline, Weeks 12 and 24, both groups showed a significant decline of viral load. And there was no significant difference between them. Both groups showed a significant increase of CD4(+) cell count. But there was no significant difference between two groups. However, the baseline CD4(+) cell count was markedly lower in the IRIS group than that in the non-IRIS group. In 85.1% (40/47) of cases, the CD4(+) cell count was HIV RNA viral load decreases in both IRIS and non-IRIS groups without any significant difference. The patients with a CD4(+) cell count < 100/µl are more vulnerable to develop IRIS.

  17. Acquired immunodeficiency syndrome-associated cancers in Sub-Saharan Africa.

    2001-04-01

    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

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

    2007-07-01

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

    Full Text Available The aim of this study was to verify the occurrence of Cryptosporidium infection in 52 human immunodeficiency virus (HIV/acquired immunodeficiency syndrome (AIDS patients (group 1 and 38 clinically healthy individuals (group 2 by using enzyme immunoassay (EIA. All fecal samples collected were submitted to the Baermann, Lutz, and Ritchie methods, the Safranin/Methylene Blue, and Weber's chromotrope modified Trichrome staining techniques, and EIA. In group 1, parasitological staining techniques and EIA were both positive for Cryptosporidium sp. infection in 3/52 (5.8% samples and both negative in 45/52 (86.5% samples, while 4/52 (7.7% samples were positive in EIA and negative in parasitological staining techniques. Concerning group 2, all samples were negative by EIA and microscopy for Cryptosporidium infection. In conclusion, EIA may be an alternative method for detecting Cryptosporidium-specific coproantigen in HIV/AIDS patients.

    Full Text Available Patent law flexibilities outlined in the Trade-related Aspects of Intellectual Property Rights agreement make it possible for low-income nations to provide affordable essential medicine during health crises. During the rise of the human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS epidemic in South Africa, multinational pharmaceutical companies challenged the implementation of these flexibilities. In response to this lawsuit, the World Trade Organization enacted the Doha Declaration, an affirmation of the right of low-income nations to import and produce generic versions of patented essential medicines. This case study assesses the Doha Declaration's impact on access to HIV/AIDS treatment in South Africa by examining drug pricing, antiretroviral treatment coverage and drug licensing fees. The declaration ultimately contributed to the decrease in HIV/AIDS treatment costs and the subsequent increase in availability and affordability of life-saving drug regimens.

    To analyze the reproductive aspects and knowledge of family planning among women with Acquired Immunodeficiency Syndrome (AIDS). Cross-sectional and descriptive study carried out from January to December, 2015, in the outpatient care of infectious disease unit in a hospital located in Fortaleza, Ceará. Data were collected through a form applied by interview in a private setting. 102 women participated in the study. Most were aware that they were serologically positive with human immunodeficiency virus (HIV) during prenatal care (96.1%) and did not intend to have more children (63.7%). Women who were less than 39 years of age, had a higher educational level, and a shorter time of antiretroviral therapy had better chances of having children (p≤0.05). Having a steady partner increased the chance of desiring to have children, while tubal ligation was higher among women that did not receive counseling on family planning. Knowledge of family planning was limited because of lack of assistance provided by health professionals. Analisar aspectos reprodutivos e conhecimento sobre planejamento familiar de mulheres com síndrome da imunodeficiência adquirida (Aids). Estudo transversal, descritivo, realizado de janeiro a dezembro de 2015, no ambulatório de infectologia de um hospital em Fortaleza, Ceará. Os dados foram coletados por meio de formulário, aplicado por entrevista em ambiente privativo. Participaram do estudo 102 mulheres. A maioria delas teve conhecimento da sorologia positiva para vírus da imunodeficiência humana (HIV) durante o pré-natal (96,1%), e estas não pretendiam mais ter filhos (63,7%). Mulheres com idade menor que 39 anos, maior escolaridade e menor tempo de terapia antirretroviral tiveram maiores chances de ter filhos (p≤0,05). Mulheres com idade menor que 39 anos e maior escolaridade tiveram maiores chances de ter informações corretas sobre ter filhos na vigência do HIV (p≤0,05).

    There is little detailed information on human immunodeficiency virus (HIV) amongst older adults in Singapore. A retrospective study of 121 consecutive referrals of patients presenting for HIV care was conducted. Demographic, clinical and laboratory variables were collected. A prognostic model derived from the North American Veterans' Affairs Cohort Study (VACS) was used to estimate prognosis. The median age at presentation was 43 (range, 18 to 76). Thirty-eight patients (31%) were aged 50 or older and 106 patients (88%) were male. Older patients were more likely to be of Chinese ethnicity (P = 0.035), married (P = 0.0001), unemployed or retired (P = 0.0001), and to have acquired their infection heterosexually (P = 0.0002). The majority of patients in both groups were symptomatic at presentation. Eighty-one (67%) had CD4 counts less than 200 at baseline with no observable differences in HIV ribonucleic acid (RNA) or clinical stage based on age. Non-Acquired Immunodeficiency Syndrome (AIDS) morbidity was observed more frequently amongst older patients. The estimated prognosis of patients differed significantly based on age. Using the VACS Index and comparing younger patients with those aged 50 and above, mean 5 year mortality estimates were 25% and 50% respectively (P HIV/AIDS cases and present with more non-AIDS morbidity. This confers a poor prognosis despite comparable findings with younger patients in terms of clinical stage, AIDS-defining illness, CD4 count and HIV viral load.

    To describe the knowledge, attitudes, and behaviors of runaway and homeless youths regarding infection with the human immunodeficiency virus (HIV). Cross-sectional, descriptive. A crisis shelter for runaway and homeless youths. One hundred one residents, aged 13 to 20 years, of a shelter for homeless and runaway youths in Houston, Tex. None. A self-administered questionnaire was used to examine the knowledge, attitudes, and behaviors of these youths regarding infection with HIV. Nearly one fourth had injected illegal drugs; one fifth had shared needles for other purposes. Sixteen percent had had anal intercourse, 19% had engaged in prostitution, and 67% of all subjects reported having four or more sexual partners. One fifth reported that they always use condoms. While quite knowledgeable about means of transmission, they held prevalent misconceptions about casual contact and risk reduction. Youths perceive few barriers to condom use, have fairly high intentions to practice preventive behavior, and have high self-efficacy to do so. Most believe they are at little or no risk for acquiring HIV. These findings support the need for medical, educational, and social service programs to reduce the risk of HIV among these youths. Runaway and homeless youths practice behaviors that place them at high risk for acquisition of HIV infection. Risk reduction is imperative and will require programs that address the educational, psychological, social, and medical needs of these youths.

    Cerebral aneurysmal arteriopathy of the circle of Willis is an uncommon manifestation of acquired human immunodeficiency virus (HIV) infection and up to now only 15 cases have been published in the literature. For this reason we add our experience of this rare case, and review the most important aspects related to this entity. The patient is a 6 year old male with perinatal transmitted AIDS, tetraparethic, developed symptoms characterized by episodes of dystonic postures. The computed tomography of the brain showed aneurismal arteriopathy of the circle of Willis. He had a previous normal examination. The review of the literature shows the pathological abnormalities of the affected vessels are mainly medial fibrosis, with destruction of the internal elastic lamina and intimal hyperplasia. The etiology for the vasculitis is unknown. Varicela zoster virus, as well as HIV by itself, can be related to the physiopathology of the vasculitis. On conclusion, it can be said that although uncommon, such complications are of great importance by the fact that the patients with vascular aneurismal arteriopathy are in high risk for vascular accidents, and once a diagnosis was made, death occurs in less than 6 months, according to the literature.

    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.

    Full Text Available 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.

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

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

    Full Text Available Background: Human immunodeficiency virus/acquired immunodeficiency syndrome is a global public health problem; enormously affecting the national economy, social development and human rights with posing a challenge to human civilization. Seasonal labor migrants are the most at risk population for HIV/AIDS and their risky sexual behaviors exacerbate its transmission. The aim of the study was to explore the HIV/AIDS related sexual behavior of migrant workers. Materials and Methods: A cross-sectional study was carried out among 372 migrant workers backing to Nepal from Banbasa border of India-Nepal during August-October 2010. Migrants having permanent residents of far western region, Nepal were individually contacted at the entry point of Nepal and interviewed in a confidential environment after obtaining informed consent. Data were analysed using the SPSS (16.0 version. Descriptive and inferencial statistics were applied considering P 3 sex partners. Most (82.25% had vaginal sex and 43.54% reported the consistent use of condom. About 64.76% had sex after drinking alcohol. Age, education, monthly income and nature of works were significant with risky behaviors. Conclusion: Inconsistent condom use, multiple sexual partners and sex after drinking alcohol have a cumulative effect on the risk of HIV transmission.

    Although discontinuation of suppressive antifungal therapy for acquired immunodeficiency syndrome (AIDS)-associated histoplasmosis is accepted for patients with immunologic recovery, there have been no published studies of this approach in clinical practice, and minimal characterization of individuals who relapse with this disease. We performed a multicenter retrospective cohort study to determine the outcome in AIDS patients following discontinuation of suppressive antifungal therapy for histoplasmosis. Ninety-seven patients were divided into a physician-discontinued suppressive therapy group (PD) (38 patients) and a physician-continued suppressive therapy group (PC) (59 patients). The 2 groups were not statistically different at baseline, but at discontinuation of therapy and at the most recent follow-up there were significant differences in adherence to therapy, human immunodeficiency virus (HIV) RNA, and urinary Histoplasma antigen concentration. There was no relapse or death attributed to histoplasmosis in the PD group compared with 36% relapse (p 150 cells/mL, HIV RNA <400 c/mL, Histoplasma antigenuria <2 ng/mL (equivalent to <4.0 units in second-generation method), and no CNS histoplasmosis.

    Full Text Available Background: Cryptococcal meningoencephalitis (CM kills about half a million human immunodeficiency virus (HIV patients per year, mostly in Africa. Aim: The aim of this study was to determine the prevalence, clinical presentation and in-hospital outcome of CM among HIV-infected patients in Douala. Materials and Methods: A cross-sectional clinical note review of 672 HIV-1 patients′ files admitted from January 1 st 2004 to December 31 st 2009 at the Internal Medicine unit of the Douala General Hospital, Cameroon was performed. Only patients diagnosed of CM by microscopy of Indian ink stained cerebrospinal fluid (CSF were studied. Results: The prevalence of CM in the study was 11.2%. Mean age of patients was 36.9 ΁ 12.7 years. Median cluster of differentiation 4 (CD4 cell count was 23 cells/μL, (interquartile range [IQR]: 10-61 and 62.7% of CD4 cell counts were <50 cells/μL. The most prevalent symptom was headache in 97.3% of patients. In CSF, median proteins was 0.9 g/L (IQR: 0.6-1; median glucose 0.2 g/L (IQR: 0.1-0.3 and median leucocyte count 54 cells/μL (IQR: 34-76 mostly of mixed cellularity. The case fatality rate was 52% and low CD4 cell count was strongly associated with death, odd ratio 4.6 (95% confidence interval: 2.6-8.0, P < 0.001. Conclusion: The high case fatality of CM in Douala warrants adequate diagnostic measures and optimization of standardized treatment to reduce mortality.

Methods : Between April 2002 and September 2003, a total of 415 HIV seropositive adult patients (297 males and 118 females attending Regional Institute of Medical Sciences (RIMS hospitals were tested for CD4+ and CD8+ T-lymphocytes by fluorescent activated cell sorter (FACS counter (Becton Dickinson. Symptomatic patients were diagnosed as per NACO clinical case definition. Results : Ranges of 0-50, 51-100, 101-200, 201-300, 301-400, 401-500 and above 500 CD4+ T-lymphocyte per microlitre were seen in 68, 52, 101, 73, 47, 31 and 43 patients respectively whereas CD8+ T-lymphocyte ranges of 0-300, 301-600, 601-900, 901-1500, 1501-2000, 2001-3500 per microlitre were seen in 29, 84, 92, 145, 40 and 25 patients respectively. One hundred and fifty patients were asymptomatic and 265 were symptomatic. CD4/CD8 ratio in asymptomatics and symptomatics were 0.13-1.69 and 0.01-0.93 respectively. Tuberculosis and candidiasis occurred in CD4+ T-lymphocyte categories between 0-400 cells per mL in symptomatics. However, cryptosporidiosis, toxoplasmosis, herpes zoster, cryptococcal meningitis, Pneumocystis carinii pneumonia, penicilliosis and cytomegalovirus retinitis were seen in patients having CD4+ T-lymphocyte less than 200 per mL. Conclusions : CD4+ T-lymphocyte was decreased in both asymptomatic and symptomatic HIV patients, The decrease was greater in symptomatics while CD8+ T-lymphocyte was increased in both except advanced stage symptomatics. CD4:CD8 ratio was reversed in both groups. Opportunistic infections correlated with different CD4+ T-lymphocyte categories.

    Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has continued to ravage the teeming populations in Nigeria, with disastrous consequences. Despite many studies and progress on HIV/AIDS in Africa, the data on the status of the patients at the commencement of therapy is lacking. The aim of this study is to determine the demographic, clinical and some laboratory features of adult HIV/AIDS patients, seen at the commencement of antiretroviral therapy (ART) in Nnamdi Azikiwe University Teaching Hospital, Nnewi, south-east Nigeria between July 2002 and October 2004. The study was a cross-sectional, descriptive study. Adult patients living with HIV/AIDS were studied using an interview administered questionnaire. Data was analyzed using Epi Info 2008 version 3.5.1. A total of 400 respondents participated in this study. The mean age was 36.8 (8.8) years. Almost 60% patients were married and the HIV concordance rate was 53.3% (136/255). Nearly 30% of the families had at least one child positive for HIV. The most common associated risky behavior was injection administered in patent medicine stores 74.5%(302/400) and the most common clinical symptom was respiratory. Of the 400 patients recruited in this study, 19 (4.8%) were lost to follow-up on the 6 months' visit, giving a follow-up rate of 95.2% (381/400). There was statistically significant difference in the mean body weight (P = 0.02), mean total white blood cell count (P HIV/AIDS patients present late and body weight, CD4(+) count and total white blood cell count seemed to recover quickly on commencement of ART. The prevalence of concordance among couples and mother to child transmission rates tended to be high. Administration of injectable at patent medicine stores and multiple sexual partners are the most significant risk factors.

    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. 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. 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. 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.

    C57BL mice (Fv-1b) develop a severe immunodeficiency disease following inoculation as adults with LP-BM5 murine leukemia virus (MuLV), a derivative of Duplan-Laterjet virus which contains B-tropic ecotropic and mink cell focus-inducing MuLVs and a putative defective genome which may be the proximal cause of disease. The stages of development of this disease were defined for C57BL mice on the basis of lymphadenopathy and splenomegaly; histopathological changes consistent with B-cell activation; and alterations in expression of cell surface antigens affected by proliferation of T cells, B cells, and macrophages. By using this disease profile as a standard, the response of adult mice of various inbred strains and selected F1 hybrids was compared. We show that although the strains which are highly sensitive are of the Fv-1b genotype (i.e., permissive for B-tropic MuLVs), certain Fv-1b strains, e.g., BALB/c and A/J, are resistant to murine acquired immunodeficiency syndrome, whereas certain Fv-1n strains (permissive for N-tropic MuLVs but restrictive for B-tropic MuLVs), notably P/N, BDP, and AKR, show moderate sensitivity and (C57BL/6 x CBA/N)F1 mice (Fv-1n/b and thus dually restrictive) are of relatively high susceptibility. The results of virus recovery tests suggest that apparently anomalous sensitivity, based on predicted Fv-1 restriction, may reflect MuLV induction and/or mutation to provide a helper virus for which the host is permissive.

    Full Text Available Background: Human immunodeficiency virus (HIV infection in India has now been prevalent over three decades, and an increasing number of children are being affected with HIV. The spectrum of pathologic lesions in children with acquired immunodeficiency syndrome (AIDS in India has not been well described. Materials and Methods: A review of systematically conducted autopsies of 11 (10 boys and 1 girl children with AIDS is presented. Results: The mode of HIV transmission in 6 children was vertical; in one it was blood transfusion and in 4 children route was presumably vertical as these were children of orphanage. The clinical manifestations were failure to thrive; 9 children, persistent gastroenteritis; 8, recurrent fever; 5, bacterial infections; 5, hepatosplenomegaly; 5, candidiasis; 1, scabies; 1, skin rash; 2, tuberculous (TB meningitis; 1 and paraplegia; in 1 child. The spectrum of pathologic lesions observed were precocious involution in thymus in 3 and dysinvolution in 2 cases. Infectious diseases comprised of TB; 4 cases, cytomegalovirus infection (CMV 4; bacterial pneumonia and meningitis; 7, and esophageal candidiasis in 2 cases. Dual or multiple infections were observed in 9 (82% cases; these comprised of two lesions in 2, three lesions in 2, four lesions in 4, and five lesions in 1 case. TB, bacterial pneumonia, meningitis, and CMV infection are the most frequent causes of death in children with AIDS. Vascular lesions showing features of arteriopathy were observed in 5 cases and brain in one case showed non-Hodgkin's lymphoma. Conclusions: This study provides a better insight into the spectrum of pathologic lesions in children with AIDS in India. TB and CMV infection has been found to be the most prevalent infection in our children.

    Low incidence of human immunodeficiency virus (HIV) infections and acquired immunodeficiency syndrome (AIDS) has been detected in Croatia so far. Toxoplasmic encephalitis (TE) is the most common opportunistic cerebral infection in AIDS patients and is highly responsive to antiparasitic chemotherapy, if treated at an early stage. We present the case of the brain biopsy confirmed as TE on a 36-year-old female patient who at admission presented with unconsciousness and a right hemiplegia. A MSCT was performed and two hypodense lesions were diagnosed. The patient’s family initially denied the presence or history of any medical problem or infection. An MRI showed multiple ring-enhanced mass lesions. An infectologist required a brain biopsy to exclude cerebral lymphoma and multiple metastases. Pathohistological analysis suggested TE. Meanwhile, patient’s blood samples were found to be HIV positive. The patient was transferred to University Hospital for Infectious Diseases in Zagreb, where she died 2 days following admission. The patient’s family terminally confessed that the patient had been HIV positive for 10 years and had refused any treatment. Family’s denial of infection as well as ‘hiding information’ concerning patient’s health from physicians involved in her treatment caused a delay in proper on-time patient treatment. We would like to emphasize that TE must be considered as a differential diagnosis in patients presenting with multiple cerebral lesions, including patients without acknowledged past history of HIV infection. A stigma towards HIV infection and ignorance of the disease still exist and therefore hinders proper treatment. PMID:24091082

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

    Purpose: The imaging characteristics of cryptococcosis in rheumatoid arthritis (RA) patients were analyzed by comparing them with those of acquired immunodeficiency syndrome (AIDS) and immunocompetent patients, and the imaging findings were correlated with pathological findings. Methods: Two radiologists retrospectively compared the computed tomographic (CT) findings of 35 episodes of pulmonary cryptococcosis in 31 patients with 3 kinds of underlying states (10 RA, 12 AIDS, 13 immunocompetent), focusing on the nature, number, and distribution of lesions. The pathological findings of 18 patients (8 RA, 2 AIDS, 8 immunocompetent) were analyzed by two pathologists, and then correlated with imaging findings. Results: The frequencies of consolidation and ground glass attenuation (GGA) were significantly higher, and the frequency of peripheral distribution was significantly lower in the RA group than in the immunocompetent group. Peripheral distribution was less common and generalized distribution was more frequent in the RA group than in the AIDS group. The pathological findings of the AIDS and immunocompetent groups reflected their immune status: There was lack of a granuloma reaction in the AIDS group, and a complete granuloma reaction in the immunocompetent group, while the findings of the RA group varied, including a complete granuloma reaction, a loose granuloma reaction and a hyper-immune reaction. Cases with the last two pathologic findings were symptomatic and showed generalized or central distribution on CT. Conclusion: Cryptococcosis in the RA group showed characteristic radiological and pathological findings compared with the other 2 groups.

    Full Text Available Primary gastric non-Hodgkin's lymphoma (NHL is a co-morbidity that can be observed during the clinical course of acquired immunodeficiency syndrome (AIDS. We evaluated the prevalence, clinical-evolutive aspects and form of endoscopic presentation of primary gastric NHL associated with AIDS. Two hundred and forty-three HIV patients were submitted to upper digestive endoscopy, with evaluation of clinical, endoscopic and histological data. A CD4 count was made by flow cytometry and viral load was determined in a branched-DNA assay. Six cases (five men; mean age: 37 years; range: 29-46 years of primary gastric NHL were detected. The median CD4 count was 140 cells/mm³ and the median viral load was 40,313 copies/mL. Upper digestive endoscopy revealed polypoid (in four patients ulcero-infiltrative (two patients and ulcerated (two patients lesions and combined polypoid and ulcerated lesions (two patients. Histology of the gastric lesions demonstrated B cell NHL (four patients and T cell NHL (two patients. Five of the six patients died of complications related to gastric NHL. We concluded that primary gastric NHL is an important cause of mortality associated with AIDS.

    Kaposi's sarcoma is frequently found in association with acquired immunodeficiency syndrome (AIDS). We report on radiotherapy for patients with AIDS-related Kaposi's sarcoma at Tokyo Metropolitan Komagome Hospital. Between April 1991 and May 1997, radiotherapy was given to 11 lesions in eight men with AIDS-related Kaposi's sarcoma to relieve their symptoms. The lesions involved the head and neck region, the legs, and the gastrointestinal tract. Radiotherapy was carried out with 4-MV photon through parallel opposed field or high energy electrons. Total doses ranged from 20 to 38 Gy, with a median of 30 Gy, delivered in 2- to 3-Gy fractions. Four patients were given other treatments prior to the radiotherapy. Acute reaction was evaluated according to the modified acute radiation morbidity scoring criteria of the Radiation Therapy Oncology Group (RTOG). Radiotherapy had relieved the symptoms in all patients at completion of this therapy. Lesions that involved the hard palate and vocal cords had completely disappeared. The lesions that received radiotherapy were controlled without symptoms until the patients died. Patients who had the head and neck region treated exhibited severe acute mucosal reaction (at a dose of 30 Gy, there was grade 2 morbidity by modified RTOG criteria, in two patients, and grade 3 in three patients) although the radiation therapy was completed for these patients. Radiotherapy promises a favorable outcome for symptom relief in AIDS-related Kaposi's sarcoma. (author)

  6. Agreement between premortem and postmortem diagnoses in patients with acquired immunodeficiency syndrome observed at a brazilian teaching hospital

    1997-01-01

    Full Text Available Acquired immunodeficiency syndrome (AIDS is one of the main causes of death in adults worldwide. More commonly than in the general population, in patients with AIDS there is substantial disagreement between causes of death which are clinically suspected and those established by postmortem examination. The findings of 52 postmortem examinations were compared to the premortem (clinical diagnoses, and there was 46% agreement between them. Fifty two percent of the patients had more than one postmortem diagnosis, and 48% had at least one AIDS-related disease not suspected clinically. Cytomegalovirus infection was the commonest (30.7% autopsy finding, but not a single case had been suspected premortem. Bacterial infection, tuberculosis, and histoplasmosis were also common, sometimes not previously suspected, postmortem findings. This study shows that multiple infections occur simultaneously in AIDS patients, and that many among them are never suspected before the postmortem examination. These findings suggest that an aggressive investigation of infections and cancers should be done in patients with AIDS, particularly in those who do not respond to therapy of an already recognized condition

    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.

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

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

    Scientific publication is commonly used to communicate research findings and in most academic/research settings, to evaluate the potential of a researcher and for recruitment and promotion. It has also been said that researchers have the duty to make public, the findings of their research. As a result, researchers are encouraged to share their research findings with the scientific world through peer review publications. In this study, we looked at the characteristics and publication rate of theses that documented studies on human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome in Cameroon. TO CHECK IF A THESIS RESULTED IN A PUBLICATION, WE SEARCHED: A database of publications on HIV in Cameroon, African Journals Online, PubMed and Google scholar. For each publication we recorded if the student was an author, the position of the student in the author listing, the journal and where the journal was indexed. We also looked at the impact factor of the journals. One hundred and thirty theses/dissertations were included in the study, 74.6% (97/130) were written as part of a medical degree (MD), 23.8% (31/130) a postgraduate (PG) degree and 1.5% (2/130) for a Doctorate/PhD. On a whole, 13.9% (18/130) of the theses resulted in at least one publication in a scientific journal with a total of 22 journal articles, giving a mean publication rate of 0.17 article/thesis, 86.4% (11/22) were indexed on PubMed, 9.1% (2/22) on African Journals Online and 4.6% (1/22) on Google scholar. One PG thesis led to two book chapters. The student was the first author in 22.7% (5/22) of the articles and not an author in 9.1% (2/22) of the articles. Student supervisor was an author in all the articles. This study reveals that most students in Cameroon failed to transform their theses/dissertations to scientific publications. This indicates an urgent need to sensitize students on the importance of presenting their research findings in scientific meetings and peer reviewed journals

    Objective Immunosuppression may increase risk for some skin cancers. We evaluated skin cancer epidemiology among persons with acquired immunodeficiency syndrome (AIDS). Design We linked data from population-based U.S. AIDS and cancer registries to evaluate risk of non-keratinocytic skin cancers (melanoma, Merkel cell carcinoma, and appendageal carcinomas, including sebaceous carcinoma) in 497,142 persons with AIDS. Methods Standardized incidence ratios (SIRs) were calculated to relate skin cancer risk to that in the general population. We used logistic regression to compare risk according to demographic factors, CD4 count, and a geographic index of ultraviolet radiation exposure. Results From 60 months before to 60 months after AIDS onset, persons with AIDS had elevated risks of melanoma (SIR=1.3, 95%CI 1.1-1.4, n=292 cases) and, more strongly, of Merkel cell carcinoma (SIR=11, 95%CI 6.3-17, n=17) and sebaceous carcinoma (SIR=8.1, 95%CI 3.2-17, n=7). Risk for appendageal carcinomas increased with progressive time relative to AIDS onset (p-trend=0.03). Risk of these skin cancers was higher in non-Hispanic whites than other racial/ethnic groups, and melanoma risk was highest among men who have sex with men. Melanoma risk was unrelated to CD4 count at AIDS onset (p=0.32). Risks for melanoma and appendageal carcinomas rose with increasing ultraviolet radiation exposure (p-trend<10-4 and p-trend=10-3, respectively). Conclusions Among persons with AIDS, there is a modest excess risk of melanoma which is not strongly related to immunosuppression and may relate to ultraviolet radiation exposure. In contrast, the greatly increased risks for Merkel cell and sebaceous carcinoma suggest an etiologic role for immunosuppression. PMID:19114864

    The early cases of acquired immune deficiency syndrome and human immunodeficiency virus type 1 (HIV-1) infection in the 1960s and 1970s in Congo-Kinshasa (Zaire), Rwanda and Burundi are reviewed. These countries appear to be the source of the HIV-1 group M epidemic, which then spread outwards to neighbouring Tanzania and Uganda in the east, and Congo-Brazzaville in the west. Further spread to Haiti and onwards to the USA can be explained by the hundreds of single men from Haiti who participated in the UNESCO educational programme in the Congo between 1960 and 1975.

    Human T-cell lymphotropic viruses designated HTLV III or LAV are considered to represent the causative agents of the acquired immunodeficiency syndrome (AIDS). Therefore a simple direct RIA or ELISA method for antibodies to distinct epitopes of HTLV III/LAV structural components would be of great value. The authors describe RIA and ELISA assays which obviate the need for purified virus or virus proteins, do not utilize infected cells and thus do not diminish the source for continuous production of viral antigens and are specific for a major core protein of HTLV III/LAV.

    The authors report two cases of bronchogenic carcinoma in patients with acquired immunodeficiency syndrome. The first patient, a ee-year-old male, developed a left hilar adenocarcinoma, with spleen and bilateral adrenal metastases. The disease progressed unfavourably, resulting in the patient's death in less than a month. The second patient, a 47-year-old male, developed a large mass in the left upper lobe, with invasion of the thoracic wall and destruction of adjacent ribs. The histopathologic study revealed a non-oat-cell carcinoma. Both patients received palliative treatment since diagnosis was established late in the course of the disease. Recent studies suggest an association between bronchogenic carcinoma and human immunodeficiency virus infection. However, an actual increase in the prevalence of bronchogenic carcinoma in HIV-positive patients remains controversial. (author)

    Full Text Available OBJECTIVE - To evaluate the cardiac abnormalities and their evolution during the course of the acquired immunodeficiency syndrome, as well as to correlate clinical and pathological data. METHODS - Twenty-one patients, admitted to the hospital with the diagnosis of acquired immunodeficiency syndrome, were prospectively studied and followed until their death. Age ranged from 19 to 42 years (17 males. ECG and echocardiogram were also obtained every six months. After death, macro- and microscopic examinations were also performed. RESULTS - The most frequent causes of referral to the hospital were: diarrhea or repeated pneumonias, tuberculosis, toxoplasmosis or Kaposi sarcoma. The most frequent findings were acute or chronic pericarditis (42% and dilated cardiomyopathy (19%. Four patients died of cardiac problems: infective endocarditis, pericarditis with pericardial effusion, bacterial myocarditis and infection by Toxoplasma gondii. CONCLUSION - Severe cardiac abnormalities were the cause of death in some patients. In the majority of the patients, a good correlation existed between clinical and anatomical-pathological data. Cardiac evaluation was important to detect early manifestations and treat them accordingly, even in asymptomatic patients.

    We have investigated monocyte function in 17 intravenous drug abusers with the clinical and laboratory features of lymphadenopathy syndrome (LAS). LAS patients had normal numbers of circulating monocytes. Monocytes from LAS patients were comparable to cells from normal donors in terms of phagocytosis of latex beads, interleukin-1 secretion, O2- release and killing of antibody-sensitized lymphoma cells or actinomycin D pretreated WEHI 164 cells. In contrast 13 out of 17 LAS subjects tested in this respect as well as six out of nine AIDS patients showed a marked defect of monocyte chemotaxis. Thus monocytes from patients with LAS or AIDS have a selective defect of monocyte chemotaxis. PMID:2998656

    Full Text Available 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.

    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.

    Full Text Available The authors report a case of metastatic gastrointestinal adenocarcinoma to the cervical spine in a patient with acquired immunodeficiency syndrome (AIDS being treated with antiretroviral therapy. The source of this tumor could not be identified despite a thorough evaluation. A 49-year-old male being treated for AIDS presents with worsening neck pain and left distal arm weakness. MRI demonstrated an erosive mass within the cervical four vertebral body extending through the pedicle on the left side. Patient underwent needle biopsy followed by combined anterior and posterior fusion procedures. Pathology demonstrated metastatic gastrointestinal adenocarcinoma without known primary origin. He is currently undergoing palliative radiotherapy. This is an unusual case of metastatic gastrointestinal adenocarcinoma to the cervical spine. This should be included on the differential diagnosis of spinal lesions in this patient population and may represent a unique tumor in patients with HIV/AIDS who are on immunosuppressive therapy.

    1997-01-01

    Full Text Available With the emergence of the human immunodeficiency virus (HIV, in patients with acquired immunodeficiency syndrome (AIDS, Toxoplasma gondii has arisen as an important opportunist pathogenic agent, especcially in the central nervous system, being the most common cause of intracerebral lesions. The incidence of Toxoplasma gondii in HIV-infected patients depends principally on the existence of latent Toxoplasma parasitosis in the population affected. Through the enzyme-linked immunosorbent assay (ELISA, IgG and IgM anti-Toxoplasma antibodies were found in 92 patients of which 46 (50.0% were IgG seropositive, and only one case (1.0% had IgM antibodies.Of the 92 patients: 53 were HIV seropositives and 39 had AIDS. The detection and monitoring of anti-Toxoplasma antibodies in HIV patients is essential, since in this group there is a high percentage risk of developing cerebral toxoplasmosis, which is the second cause of death in this type of patients.

  2. The socioeconomic impact of human immunodeficiency virus / acquired immune deficiency syndrome in India and its relevance to eye care

    2008-01-01

    Full Text Available Human immunodeficiency virus (HIV infection is aptly called the modern day ′plague′ and has the potential to decimate people in the productive age group. On the other hand, the increasing life expectancy in developing countries spirals age-related blindness. One therefore reduces economic productivity while the other increases economic dependency. Both lead to increased expenditure of households though in different proportions. Human immunodeficiency virus and blindness are both associated with discrimination, stigma and long-term consequences. They impact the socioeconomic fabric of the affected individuals, communities and countries. The loss in productivity and the cost of support to the affected individuals are seen in both. Each is a potent problem on its own but together they spell disaster in geometric proportions rather than a simple additive effect. Strategies need to be evolved to provide solace and improve the quality of life of an HIV-positive blind individual.

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

    Full Text Available Diferentes síndromes reumáticas e fenômenos auto-imunes já foram associados à infecção pelo vírus da imunodeficiência humana (HIV, quer pela maior freqüência de adoecimento, quer pela maior gravidade. Ademais, em muitos casos, sintomas e sinais da doença reumática estão presentes na abertura do quadro de infecção pelo HIV (como na síndrome de soroconversão ou da síndrome de imunodeficiência adquirida (AIDS. O reconhecimento deste horizonte é da maior importância para a prática do reumatologista, tornando-se altamente necessário ampliar a familiaridade com estes conceitos. Revisitar as interseções reumatológicas da infecção pelo HIV - enfatizando-se situações como as espondiloartropatias soronegativas, as artralgias, as artrites infecciosas, fibromialgia, miopatias, vasculites, síndrome linfocítica infiltrante difusa, lúpus eritematoso sistêmico e fenômenos auto-imunes - é, pois, o objetivo do presente artigo.Different rheumatic syndromes and auto-immune phenomena have already been associated with the infection by the human immunodeficiency virus (HIV, either by the higher frequency of the disease or by the greater severity. Furthermore, in many cases, symptoms and signs of rheumatic disease are present at the beginning of the infection condition by HIV (as in the serum conversion or the Acquired Immunodeficiency Syndrome (AIDS. Recognition of these possibilities is of fundamental importance to the rheumatologist practice and is necessary to have familiarity with these concepts. Revisiting the rheumatologic intersections of the infection by HIV - emphasizing situations such as seronegative spondyloarthropathies, arthralgia, infectitious arthritis, fibromyalgia, myopathy, vasculitis, difuse infiltranting lymphocytic syndrome systemic lupus erythematous and auto-immune phenomena - is then, the aim of the present article.

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

    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.

    Full Text Available Background: Illness uncertainty is a source of a chronic and pervasive psychological stress for people living with human immunodeficiency virus (HIV/acquired immune deficiency syndrome (AIDS (PLWH, and largely affects their quality of life and the ability to cope with the disease. Based on the uncertainty in illness theory, the social support is one of the illness uncertainty antecedents, and influences the level of uncertainty perceived by patients. Aim: To examine uncertainty in PLWH and its correlation with social support in Iran. Materials and Methods: This cross-sectional correlational study was conducted with 80 PLWH presenting to AIDS Research Center, Tehran, Iran in 2013. The data collected using illness uncertainty and social support inventories were analyzed through Pearson′s correlation coefficient, Spearman′s correlation coefficient, and regression analysis. Results: The results showed a high level of illness uncertainty in PLWH and a negative significant correlation between perceived social support and illness uncertainty ( P = 0.01, r = -0.29. Conclusion: Uncertainty is a serious aspect of illness experience in Iranian PLWH. Providing adequate, structured information to patients as well as opportunities to discuss their concerns with other PLWH and receive emotional support from their health care providers may be worthwhile.

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

    Virulence of Rhodococcus equi strains from 20 humans in Brazil was investigated by using a polymerase chain reaction to characterize isolates as virulent (VapA), intermediately virulent (VapB), and avirulent. Nine isolates were obtained from human immunodeficiency virus (HIV)–positive patients, six from HIV-negative patients, and five from patients of unknown status. Five isolates were VapB positive, four were VapA positive, and eleven were avirulent. Among the nine isolates from HIV-positive patients, five contained VapB plasmids and two contained VapA plasmids. Five VapB-positive isolates had the type 8 virulence plasmid. Eleven of the patients had a history of contact with livestock and/or a farm environment, and none had contact with pigs. PMID:21896813

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

    The lipodystrophy syndrome is characterized by selective loss of subcutaneous fat on the face and extremities (lipoatrophy) and/or accumulation of fat around the neck, abdomen, and thorax (lipohypertrophy). The aim of this study has been to assess the impact of polymethylmethacrylate facial treatment on quality of life, self-perceived facial image, and the severity of depressive symptoms in patients living with HIV/AIDS. A non-randomized before and after interventional study was developed. Fifty-one patients underwent facial filling. The self-perceived quality of life, facial image, and degree of depressive symptoms were measured by the Short-Form 36 and HIV/AIDS--Targeted quality of life questionnaires, by a visual analogue scale and by the Beck depression inventory, respectively, before and three months after treatment. Six of the eight domains of Short-Form 36 and eight of the nine dimensions of the HIV/AIDS--Targeted quality of life questionnaires, together with the visual analogue scale and by the Beck depression inventory scores, revealed a statistically significant improvement. The only adverse effects registered were edema and ecchymosis. The treatment of facial lipoatrophy improved the self-perceived quality of life and facial image as well as any depressive symptoms among patients with HIV/AIDS. © 2014 The International Society of Dermatology.

Settings and Design: We retrospectively selected cases of AIDS-related benign lymphadenopathy. Cases with lymphomas, frank granulomas and necrosis were excluded. We analyzed different morphological patterns and correlated these with immunophenotypic markers along with viral markers human herpesvirus 8-latency-associated nuclear antigen (HHV8-LANA, and Epstein-Barr virus-encoded ribonucleic acid (EBER studies via in situ hybridization (EBER-ISH. Materials and Methods: We present the morphological patterns of 13 cases of human immunodeficiency virus (HIV-reactive lymph nodes and their clinical, hematological, biochemical and radiological parameters with special emphasis on the presence or absence of viral markers, including HHV8 and EBV. Results: Common patterns included follicular hyperplasia only (five cases, mixed pattern of follicular hyperplasia with burnt-out germinal centres (four cases, completely atretic follicle (two cases, folliculolysis (11 cases, dumbbell-shaped follicles (three each, progressive transformation of germinal centers (four cases, T-zone expansion (two cases, Reed Sternberg (RS cells like immunoblasts (two cases, Castleman′s-like features with lollipop-like follicles (three cases and a spindle cell prominence (one case. CD8+ T-cells were predominant in 12 cases. CD8+ T-cells were prominent in germinal centers (eight cases. Plasmablasts were seen in four cases within the perigerminal center area. Immunohistochemistry for HHV8, i.e. HHV8-LANA were negative in all cases while EBER was detected in 11 cases in the centrocyte-like B cells. Two cases of multicentric Castleman′s disease expressed EBER; however, they did not express HHV8. Conclusion: The wide spectrum of histological changes in HIV-associated lymphadenopathy requires recognition. The histological changes can mimic those of other infective

    We assessed non-liver-related non-acquired immunodeficiency syndrome (AIDS)-related (NLR-NAR) events and mortality in a cohort of human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients treated with interferon (IFN) and ribavirin (RBV), between 2000 and 2008. The censoring date was May 31, 2014. Cox regression analysis was performed to assess the adjusted hazard rate (HR) of overall death in responders and nonresponders. Fine and Gray regression analysis was conducted to determine the adjusted subhazard rate (sHR) of NLR deaths and NLR-NAR events considering death as the competing risk. The NLR-NAR events analyzed included diabetes mellitus, chronic renal failure, cardiovascular events, NLR-NAR cancer, bone events, and non-AIDS-related infections. The variables for adjustment were age, sex, past AIDS, HIV transmission category, nadir CD4(+) T-cell count, antiretroviral therapy, HIV RNA, liver fibrosis, HCV genotype, and exposure to specific anti-HIV drugs. Of the 1,625 patients included, 592 (36%) had a sustained viral response (SVR). After a median 5-year follow-up, SVR was found to be associated with a significant decrease in the hazard of diabetes mellitus (sHR, 0.57; 95% confidence interval [CI], 0.35-0.93; P = 0.024) and decline in the hazard of chronic renal failure close to the threshold of significance (sHR, 0.43; 95% CI, 0.17-1.09; P = 0.075). Our data suggest that eradication of HCV in coinfected patients is associated not only with a reduction in the frequency of death, HIV progression, and liver-related events, but also with a reduced hazard of diabetes mellitus and possibly of chronic renal failure. These findings argue for the prescription of HCV therapy in coinfected patients regardless of fibrosis stage. (Hepatology 2017;66:344-356). © 2017 The Authors.

    Extracerebral and cerebral pathology in AIDS (with particular emphasis on the opportunistic infections). The Authors present the extracerebral pathology of 27 cases of AIDS observed at the Department of Pathology of Milan and the cerebral pathology of 80 cases of AIDS collected by three Institutes (Department of Pathology of Milan, Department of Pathology of Rimini and Department of Neuropathology of Münster) with particular emphasis on the pathology of the opportunistic infections. In the adults' group, the most frequent infections are the protozoan ones (T. gondii) followed with equal incidence by the viral and fungal diseases. In the pediatric group the viral diseases are the most frequently seen. Almost all of the adults show multiple infections in the same organ or in different organs. Diffuse lesions with heavy pathologic fields were observed also without tissue reaction. As to cerebral pathology AIDS' patients with opportunistic infections show focal symptoms, whereas the so called "subacute microglial encephalitis" generally appears as a demential syndrome. In cases with progressive multifocal leukoencephalopathy JC virus was always found and in one case also SV 40 - and BK virus. The diffuse demyelinization in some cases of HIV-Encephalopathy is aspecific. In HIV-positive newborns with cerebral signs, the lesions are characterized by oedema, spongiosis and microcalcifications of the basal ganglia; these are aspecific lesions which can be found in toxic and infectious encephalopathies.

    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.

    Oral health care of patients with human immunodeficiency virus (HIV)/acquired immune-deficiency syndrome (AIDS) is a growing area of concern. Information on HIV- and AIDS-related knowledge among dental students provides a crucial foundation for efforts aimed at developing an appropriate dental curriculum on HIV and AIDS. The purpose of this study was to assess the knowledge and attitude of Indian clinical dental students towards the treatment of patients with HIV/AIDS and perceived sources of information regarding HIV-related issues. Data were collected from clinical dental students (third year, fourth year and internship) from three dental institutions in Delhi National Capital Region (NCR). The questions assessed the knowledge and attitude towards treatment of patients with HIV and the perceived source of information related to HIV. The willingness to treat HIV-positive patients among dental students was 67.0%, and 74.20% were confident of treating a patient with HIV/AIDS. The potential problems in rendering treatment to these patients were effect on the attitude of other patients (49.90%) and staff fears (52.50%). The correct knowledge regarding the infection-control practice (barrier technique) was found among only 15.50% of respondents. The respondents had sufficient knowledge regarding the oral manifestations of HIV/AIDS. There was no correlation between the knowledge and attitude score, demonstrating a gap between knowledge and attitude among dental students regarding treatment of HIV-infected patients. Appropriate knowledge has to be delivered through the dental education curriculum, which can instil confidence in students about their ability to manage HIV-positive patients. © 2014 FDI World Dental Federation.

The majority, 112 (74.67% patients were between 20 and 50 years of age and 116 (77.3% patients were either illiterate or high-school dropouts. Drivers, laborers, and self-employed comprised 69 (74.2% patients among affected males. Only 129 (86% respondents had heard about HIV/AIDS and knew about its heterosexual transmission. Ninety-eight (65.3% respondents were aware of disease transmission from infected blood or needle pricks. Interestingly, 106 (70.7% respondents were aware of the importance of using condom in preventing disease transmission. Television/radio was the most common sources of information for 135 (90% patients. Nearly, 69% respondents disfavored disclosing their disease to friends/colleagues fearing stigmatization. Conclusions: Information, education, and communication activities are imperative to educate persons living with HIV/AIDS about life-long nature of the disease, modes of its transmission, and significance of preventive measures to bridge the gaps in their knowledge. While improvement in individual economic status, education, and health services remains highly desirable, mass media can play a pivotal role in creating awareness among masses.

    Sterno-costo-clavicular hyperostosis (SCCH) is the most common manifestation of a syndrome, consisting of increased bone metabolism, mostly new bone formation and heterotopic ossification of fibrous tissue, which we have characterised as the acquired hyperostosis syndrome. In part I we discuss the terminology, radiological appearances, scintigraphy, clinical and laboratory findings, bacteriology, histology, nosology, complications, treatment and differential diagnosis of SCCH. Chronic recurrent multifocal osteomyelitis (CRMO) is regarded as a phaenotype of SCCH, depending on the age. CRMO occurs in children, adolescents and young adults, SCCH predominantly in middleaged and elderly adults.

    Studies show that nearly 40 million people are living with human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) around the world and since the beginning of the epidemic, about 35 million have died from AIDS. Heterosexual intercourse is the most common route for transmission of HIV infection (85%). People with a sexually transmitted infection (STI), such as syphilis, genital herpes, chancroid, or bacterial vaginosis, are more likely to obtain HIV infection during sex. On the other hand, a patient with HIV can acquire other infections such as hepatitis C virus (HCV) and hepatitis B virus (HBV) and also STIs. Co-infections and co-morbidities can affect the treatment route of patients with HIV/AIDs. Sometimes, physicians should treat these infections before treating the HIV infection. Therefore, it is important to identify co-infection or comorbidity in patients with HIV/AIDS. This study was conducted in order to understand the prevalence of HIV/AIDS/STI co-infection. In this cross-sectional study, we evaluated all HIV/AIDS patients who were admitted to the infectious wards of Boo-Ali hospital (Southeastern Iran) between March 2000 and January 2015. All HIV/AIDS patients were studied for sexually transmitted infections (STI) such as syphilis, gonorrhea, hepatitis B virus (HBV) and genital herpes. A questionnaire including data on age, sex, job, history of vaccination against HBV, hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), hepatitis B surface antigen (anti-HBs), HCV-Ab, venereal disease research laboratory (VDRL) test, fluorescent treponemal antibody absorption (FTA-Abs) test, and urine culture was designed. Data was analyzed by the Chi square test and P values of VDRL. The FTA-Abs was positive for all patients who were positive for VDRL. Gonorrhea was found in seven patients (17%) and three cases had genital herpes in clinical examinations. All patients who had positive test results for these STIs

    @@ Acquired von Willebrand syndrome (AvWS) is kind of bleeding disorder with laboratory findings similar to those in congenital yon Willebrand disease (vWD).AvWS doesn's have any personal or family history of bleeding, but is associated with certain diseases or abnormal conditions or drugs. Although AvWS is being stated as a rare disease, it has gained more and more attention during the past years. Not because of the severity of the disease, but it is more common than we thought and most patients don' t have a proper diagnosis.

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

    We present the main findings observed on the high-resolution computed tomography examinations of 15 patients with acquired immunodeficiency syndrome and Pneumocystis carinii pneumonia. The high-resolution computed tomography and autopsy findings of 5 patients were also compared. The most frequently observed high-resolution computed tomography patterns were ground-glass attenuation, consolidation areas, crazy-paving pattern and cysts. Nodules and intralobular reticulation were less frequently observed. Ground-glass attenuation and consolidation areas corresponded to alveolar filling with inflammatory exudate. Thickening of the interlobular septa was due to cell infiltration and edema. One patient presented interlobular reticulation, and the pathology study revealed alveolar septa thickening due to cell infiltration and fibrosis. Nodules observed in one of the patients corresponded to a patchy intra alveolar accumulation of microorganisms and inflammatory cells forming a 'granulomatous' pattern. (author)

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

    Full Text Available 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.

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

    Full Text Available Dermatophytes are keratinophilic fungi responsible for benign and common forms of infection worldwide. However, they can lead to rare and severe diseases in immunocompromised patients. Severe forms include extensive and/or invasive dermatophytosis, i.e., deep dermatophytosis and Majocchi’s granuloma. They are reported in immunocompromised hosts with primary (autosomal recessive CARD9 deficiency or acquired (solid organ transplantation, autoimmune diseases requiring immunosuppressive treatments, HIV infection immunodeficiencies. The clinical manifestations of the infection are not specific. Lymph node and organ involvement may also occur. Diagnosis requires both mycological and histological findings. There is no consensus on treatment. Systemic antifungal agents such as terbinafine and azoles (itraconazole or posaconazole are effective. However, long-term outcome and treatment management depend on the site and extent of the infection and the nature of the underlying immunodeficiency.

    2011-09-01

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

MÉTODOS: Análise do banco de dados do Sistema de Vigilância Epidemiológica do Programa de Doenças Sexualmente Transmissíveis e Síndrome da Imunodeficiência Adquirida da Cidade do Rio de Janeiro, no período de 1993 a 2002. RESULTADOS: A expansão da definição de casos de síndrome da imunodeficiência adquirida ocorrida em 1998 criou um aumento substancial no número de casos notificados de síndrome da imunodeficiência adquirida, principalmente por aqueles que passaram a ser definidos pelo critério imunológico. Dentre os casos de síndrome da imunodeficiência adquirida que foram definidos apenas por doença, a candidíase em suas diversas formas manteve-se como a doença oportunista de maior freqüência no momento da notificação. Embora a pneumonia por Pneumocystis carinii se apresentasse como a segunda doença mais freqüente na maioria dos anos observados, a partir de 2001, a tuberculose ultrapassou-a em freqüência, tornando-se a segunda doença mais freqüente no momento da notificação dos casos de síndrome da imunodeficiência adquirida. CONCLUSÃO: Apesar da diminuição do número de casos de síndrome da imunodeficiência adquirida definidos por doença, a tuberculose manteve-se como um importante evento definidor dessa síndrome, sendo atualmente de ocorrência mais freqüente do que a pneumonia por Pneumocystis carinii e a toxoplasmose, provavelmente por sua alta taxa de prevalência na cidade.OBJECTIVE: To analyze the frequency of tuberculosis and of the other principal opportunistic infections defining acquired immunodeficiency syndrome at the time such cases were reported in the city of Rio de Janeiro, Brazil.

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

    Full Text Available TEMA: a Síndrome da Imunodeficiência Adquirida (SIDA/AIDS é causada pelo Vírus da Imunodeficiência Humana (VIH/HIV, e resulta numa imunidade reduzida, o que torna o indivíduo mais susceptível a doenças e infecções oportunistas. Com o avanço da doença as estruturas do sistema auditivo central podem ser comprometidas pela ação direta do vírus ou decorrente de infecções secundárias e neoplasias. O portador do HIV/AIDS pode também se tornar mais vulnerável a outras patologias do ouvido. OBJETIVO: o objetivo desta revisão foi exploratório, visando identificar os possíveis pontos de interseção entre distúrbios auditivos e a Síndrome da Imunodeficiência Adquirida. Realizou-se uma revisão da literatura sobre a saúde auditiva dos portadores de HIV/AIDS e foi discutido o impacto potencial de patologias auditivas na qualidade de vida. CONCLUSÃO: a literatura sugere que várias possiveis associações existam entre os distúrbios auditivos e a Síndrome da Imunodeficiência Adquirida e o Vírus da Imunodeficiência Humana. Profissionais de saúde, inclusive aqueles dos serviços públicos no Brasil, deveriam examinar a necessidade de iniciativas de saúde auditiva dirigida aos portadores de HIV/AIDS para prevenir patologias auditivas ou reduzir seu impacto na qualidade de vida.BACKGROUND: Acquired Immunodeficiency Syndrome (or Acquired immune deficiency syndrome or AIDS is caused by the Human Immunodeficiency Virus (HIV and results in reduced immunity, leaving affected individuals more susceptible to illness and opportunistic infections.

    Full Text Available The introduction of highly active antiretroviral therapy (HAART has significantly improved the clinical outcome of HIV disease, with increased survival rates. However, the introduction of HAART has generated a contrast in the cardiac manifestations of AIDS. In developed countries, we observed an approximate 30% reduction in the prevalence of HIV-associated cardiomyopathy, possibly related to a reduction of opportunistic infections and myocarditis. In developing countries, however, where the availability of HAART is limited and the pathogenic impact of nutritional factors is significant, we observed an increase of approximately 32% in the prevalence of HIV-associated cardiomyopathy and a related high mortality rate from congestive heart failure. Also, some HAART regimens in developed countries, especially those including protease inhibitors, have been shown to cause, in a high proportion of HIV-infected patients, a iatrogenic metabolic syndrome (HIV-lipodystrophy syndrome.This is associated with an increased risk of atherosclerosis-related cardiovascular events even in young HIV-infected people. A better understanding of the molecular mechanisms responsible for this syndrome will lead to the discovery of new drugs that will reduce cardiovascular risk in HIV-infected patients receiving HAART.A introdução da terapia antitroviral altamente potente (HAART melhorou significativamente a evolução clínica da infecção pelo HIV com um aumento nas taxas de sobrevida. Apesar deste benefício, o uso da HAART gerou contrastes nas manifestações cardíacas da Aids. Nos países desenvolvidos, observou-se uma redução de aproximadamente 30% na prevalência de cardiomiopatia associada ao HIV, possivelmente relacionada à redução das infecções oportunistas e da miocardite. Nos países em desenvolvimento, entretanto, aonde a disponibilidade da HAART é limitada e o impacto patogênico dos fatores nutricionais é significante, observou-se um aumento de

The high prevalence and complications of esophagitis are well documented. AIM: Graduate esophagitis; identify microorganisms like Candida sp, cytomegalovirus, herpesvirus and mycobacteria; identify by immunohistochemical staining viral agents cytomegalovirus, herpesvirus I, herpesvirus II, Epstein-Barr Virus, human papilloma virus and human immunodeficiency virus; verify how immunohistochemistry changes the profile of esophagitis; verify the association between the histological and endoscopical findings; verify the relevance of the number of fragments studied in the characterization of the histological agents. METHODS: We studied retrospectively esophageal biopsies in 227 patients with acquired immunodeficiency virus syndrome using hematoxylin and eosin, PAS (periodic acid of Schiff, Groccott and Ziehl-Nielsen stains and immunoperoxidase stains to detect opportunistic agents. Endoscopic aspects were studied. RESULTS: The non-specific esophagitis grade III, in the inferior third of the esophagus, was the most frequent type. Candida sp was the most frequent agent, followed by viruses cytomegalovirus, herpesvirus and mycobacteria. The presence of plaque and ulceration suggested the diagnosis of esophageal candidiasis and cytomegalovirus esophagitis. Immunohistochemical allowed the characterization of cytomegalovirus and of herpesvirus in those cases where other techniques could not achieve it, furthermore the cytomegalovirus was also found in histological normal cases, making the use of this technique advisable in routine diagnosis.

    Full Text Available A mathematical model SEIA (susceptible-exposed-infectious-AIDS infected with vertical transmission of AIDS epidemic is formulated. AIDS is one of the largest health problems, the world is currently facing. Even with anti-retroviral therapies (ART, many resource-constrained countries are unable to meet the treatment needs of their infected populations. We consider a function of number of AIDS cases in a community with an inverse relation. A stated theorem with proof and an example to illustrate it, is given to find the equilibrium points of the model. The disease-free equilibrium of the model is investigated by finding next generation matrix and basic reproduction number R0 of the model. The disease-free equilibrium of the AIDS model system is locally asymptotically stable if R0⩽1 and unstable if R0>1. Finally, numerical simulations are presented to illustrate the results.

    The unique nature of the replication cycle of the retroviruses, including HIV, offera number of possible targets for chemotherapeutic agents. These are RNA viruses which have the capacity to make DNA copies through their characteristic enzyme, reverse transcriptase, encoded in the pole region of the viral genoma. Reverse transcription is an attractive target for therapeutic intervention as this event is uniquelly associated with retroviruses. Dideoxynucleoside analogues can compete with endogenous nucleosides that are the natural substrate for reverse transcriptase or may be incorporated intro the growing chain of proviral DNA and terminate elongation. Reverse transcriptase inhibition is the principal mechanism of action of zidovudine (AZT) and related nucleosides, dideoxyinosine (ddl) and dideoxycitidine (ddC), which all attach to reverse transcriptase to the same site. This review will discuss current approaches to the antiretroviral therapy in AIDS patients. Several well controlled clinical trials have established both the efficacy and toxicity of AZT in patients with AIDS and severe ARC and it was shown that this drug decreased the incidence and severity of opportunistic infections, with the highly significant reduction in early mortality. The efficacy of newer reverse transcriptase-inhibiting nucleoside derivatives will be discussed too, as well as the issue of combination therapies.

    Acquired immune deficiency syndrome (AIDS) is an immune deficiency disease. The etiology of hyperthyroidism, which can also be immune-related, is usually divided into six classical categories, including hypophyseal, hypothalamic, thyroid, neoplastic, autoimmune and inflammatory hyperthyroidism. Hyperthyroidism is a rare complication of highly active antimicrobial therapy (HAART) for human immunodeficiency virus (HIV). Hyperthyroidism caused directly by AIDS has not been previously reported. A 29-year-old man who complained of dyspnea and asthenia for 1 month, recurrent fever for more than 20 days, and breathlessness for 1 week was admitted to our hospital. The thyroid function test showed that the level of free thyroxine (FT4) was higher than normal and that the level of thyroid-stimulating hormone (TSH) was below normal. He was diagnosed with hyperthyroidism. Additional investigations revealed a low serum albumin level and chest infection, along with diffuse lung fibrosis. Within 1 month, he experienced significant weight loss, no hand tremors, intolerance of heat, and perspiration proneness. We recommended an HIV examination; subsequently, AIDS was diagnosed based on the laboratory parameters. This is the first reported case of hyperthyroidism caused by AIDS. AIDS may cause hyperthyroidism by immunization regulation with complex, atypical, and easily ignored symptoms. Although hyperthyroidism is rare in patients with AIDS, clinicians should be aware of this potential interaction and should carefully monitor thyroid function in HIV-positive patients.

    Objective To investigate the effects of health education on acquired immunodeficiency syndrome and sexually transmitted disease-related knowledge, attitude and practice among migrant construction workers. Methods Cluster random sampling was adopted to select 1 031 male migrant construction workers from 3 construction sites in a district of Shanghai, health education on acquired immunodeficiency syndrome and sexually transmitted diseases were conducted, and the effects of health education were evaluated. Results The awareness rate of acquired immunodeficiency syndrome and sexually transmitted disease-related knowledge after health education was significantly higher than that before health education among migrant construction workers (P < 0. 001). The awareness rate of transmission routes ( sex transmission, blood transmission and vertical transmission) and non-transmission routes of acquired immunodeficiency syndrome was significantly increased after health education, especially on " antibody can not be detected during window period", "relationship between sexually transmitted diseases and acquired immunodeficiency syndrome" and "sexually transmitted diseases can be prevented by avoiding premarital sex". The attitude toward premarital sex and patients with acquired immunodeficiency syndrome was significantly changed after health education. Among all the migrant construction workers, 49.4% chose not to avoid people infected with human immunodeficiency virus, and 64. 5% believed that patients with acquired immunodeficiency syndrome should live and work like a normal person. Behavior survey indicated that 54. 9% of migrant construction workers were for the use of condoms after health education. AH the above attitude and behavior were significantly different from those before health education ( P < 0. 01). Conclusion Health education is an effective measure to improve acquired immunodeficiency syndrome and sexually transmitted disease-related knowledge, attitude and

    The chromosomal breakage syndromes--ataxia-telangiectasia, Fanconi's anemia, and Bloom's syndrome--are associated with growth failure, neurologic abnormalities, immunodeficiency, and an increased incidence of malignancy. The relationship between these features is unknown. We recently evaluated a 21-year-old female with more severe chromosomal breakage, immunodeficiency, and growth failure than in any of the mentioned disorders. As of November 1985, the patient remains clinically free of malignancy. At age 18, the patient's weight was 22.6 kg (50th percentile for seven years), height was 129 cm (50th percentile for eight years), and head circumference was 42 cm (50th percentile for six months). Laboratory studies demonstrated a marked decrease in both B and T cell number and function. The peripheral blood contained 400 to 900 lymphocytes/microL with 32% T11 cells, 17% T4 cells, and 21% T8 cells. The proliferative responses to phytohemagglutinin (PHA), pokeweed mitogen, and concanavalin A were less than 10% of control. There were 1% surface IgM positive cells, and serum IgG was 185 mg/dL, IgM 7 mg/dL, IgA 5 mg/dL. In lymphocyte cultures stimulated with the T cell mitogens PHA, phorbol ester, and interleukin 2, 55% of the banded metaphases demonstrated breaks or rearrangements. The majority of the breaks involved four fragile sites on chromosomes 7 and 14, 7p13, 7q35, 14q11, and 14q32. These are the sites of the genes for the T cell-antigen receptor and the immunoglobulin heavy chain and are sites of gene rearrangement in lymphocyte differentiation. Epstein-Barr virus stimulated B cells and fibroblast cultures also demonstrated a high incidence of breaks, but the sites were less selective. These findings suggest that the sites of chromosomal fragility in the chromosomal breakage syndromes may be informative and that factors other than the severity of the immunodeficiency or the high incidence of chromosomal damage may contribute to the occurrence of malignancy in the

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

    Full Text Available Abstract Goldenhar syndrome (GS results from an aberrant development of the 1st and 2nd branchial arches. There is a wide range of clinical manifestations, the most common being microtia, hemifacial microsomia, epibulbar dermoids and vertebral malformations. We present two cases of GS and secondary immunodeficiency due to anatomical defects characteristic of this disorder. Case 1 (3-year-old female averaged 6 episodes of sinusitis and otitis media per year. Case 2 (7-year-old female also had recurrent otitis media, an episode of bacterial pneumonia, and 2 episodes of bacterial meningitis. Their immune evaluation included a complete blood count with differential, serum immunoglobulin levels and specific antibody concentrations, lymphocyte phenotyping, and mitogen and antigen responses, the results of which were all within normal ranges. Both children demonstrated major structural abnormalities of the inner and middle ear structures, retention of fluid in mastoid air cells, and chronic sinusitis by computed tomography. These two cases illustrate how a genetically-associated deviation of the middle ear cleft can cause recurrent infections and chronic inflammation of the middle ear and adjacent sinuses, even meninges, leading to a greatly reduced quality of life for the child and parents.

    The acquired alexia with agraphia syndrome is a conspicuous disorder of reading and writing in the absence of significant other language impairments that has mainly been recorded in adults. Pure cases are rare, with most patients displaying mild aphasic deficits. In children, acquired reading and writing disorders are generally reported as part of more encompassing aphasic syndromes affecting oral and written language equally, for example, Broca or Wernicke aphasia. Documented instances of predominant acquired reading and writing disorders in childhood are exceptional. We report an 11-year-old, right-handed boy who sustained a left temporoparieto-occipital hematoma following rupture of an arteriovenous malformation and who consecutively presented with the acquired alexia with agraphia syndrome associated with word-finding difficulties. Neuropsychologic and neurolinguistic data showed that there was no concomitant Gerstmann and/or angular gyrus syndrome. Th e recoveryfrom the anomia was quite favorable, but recovery of written language was more protracted and acted on the patient's further scholastic achievement. This case is reminiscent of a historical childhood case reported in 1939 and is consonant with adult cases in terms of lesion location and semiologic picture.

    Full Text Available DOCK8 immunodeficiency syndrome (DIDS is a combined immunodeficiency characterized by recurrent viral infections, severe atopy, and early onset malignancy. Genetic studies revealed large, unique deletions in patients from different families and ethnic backgrounds. Clinical markers of DIDS include atopic dermatitis, allergies, cutaneous viral infections, recurrent respiratory tract infections, and malignancy. Immune assessments showed T cell lymphopenia, hyper-IgE, hypo-IgM, and eosinophilia. The impaired lymphocyte functions in DIDS patients appear central for disease pathogenesis.

    Full Text Available A dilatação aneurismática dos vasos do polígono de Willis é manifestação incomum da infecção pelo vírus da imunodeficiência adquirida (HIV, tendo sido relatados, até o momento, 15 casos na literatura. O presente estudo tem por objetivo relatar um novo caso dessa apresentação rara, além de revisar aspectos importantes relacionados à mesma. Um paciente, do sexo masculino, 6 anos de idade, com síndrome da imunodeficiência adquirida (AIDS de transmissão perinatal e tetraparesia, desenvolveu sintomas caracterizados por episódios de crises distônicas. A tomografia computadorizada de crânio, que inicialmente era normal, mostrou dilatação aneurismática dos vasos do polígono de Willis. A revisão de literatura demonstra que os principais achados patológicos em casos similares, são, principalmente, fibrose de camada média com destruição da lâmina interna e hiperplasia da íntima. A etiologia da vasculite não é conhecida, acreditando-se que o vírus da varicela-zoster e o próprio HIV possam estar relacionados à mesma. Conclui-se que, apesar de incomum, tal complicação apresenta grande importância pelo fato dos aneurismas colocarem esses pacientes em grupo de alto risco para acidentes vasculares. A sobrevida relatada na literatura é de menos de 6 meses após o diagnóstico da arteriopatia aneurismática cerebral.Cerebral aneurysmal arteriopathy of the circle of Willis is an uncommon manifestation of acquired human immunodeficiency virus (HIV infection and up to now only 15 cases have been published in the literature.

    Full Text Available One out of three pediatric sepsis deaths in high income countries occur in previously healthy children. Primary immunodeficiencies have been postulated to underlie fulminant sepsis, but this concept remains to be confirmed in clinical practice. Pseudomonas aeruginosa (P. aeruginosa is a common bacterium mostly associated with healthcare-related infections in immunocompromised individuals. However, in rare cases, it can cause sepsis in previously healthy children. We used exome sequencing and bioinformatic analysis to systematically search for genetic factors underpinning severe P. aeruginosa infection in the pediatric population. We collected blood samples from 11 previously healthy children, with no family history of immunodeficiency, who presented with severe sepsis due to community-acquired P. aeruginosa bacteremia. Genomic DNA was extracted from blood or tissue samples obtained intravitam or postmortem. We obtained high-coverage exome sequencing data and searched for rare loss-of-function variants. After rigorous filtrations, 12 potentially causal variants were identified. 2 out of 8 (25% fatal cases were found to carry novel pathogenic variants in primary immunodeficiency genes, including BTK and DNMT3B. This study demonstrates that exome sequencing allows to identify rare, deleterious human genetic variants responsible for fulminant sepsis in apparently healthy children. Diagnosing primary immunodeficiencies in such patients is of high relevance to survivors and affected families. We propose that unusually severe and fatal sepsis cases in previously healthy children should be considered for exome/genome sequencing to search for underlying primary immunodeficiencies.

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

    Through the analysis of a rare disorder called ataxia-telangiectasia (A-T), many important biological lessons have been gleaned. Today, it is clear that the underlying defect of A-T lies in the nucleus, as an inability to repair or process double strand breaks. More important, by the A-T phenotype now allows us to appreciate a much more general distinction between immunodeficiencies that are radiosensitive and those that are not.

    Kaposi sarcoma (KS) is an endothelial malignancy caused by human herpes virus-8 (HHV-8) infection. The epidemic and iatrogenic forms of childhood KS result from a profound and acquired T cell deficiency. Recent studies have shown that classic KS of childhood can result from rare single-gene inborn errors of immunity, with mutations in WAS, IFNGR1, STIM1, and TNFRSF4. The pathogenesis of the endemic form of childhood KS has remained elusive. We review childhood KS pathogenesis and its relationship to inherited and acquired immunodeficiency to oncogenic HHV-8.

    acquired immunodeficiency syndrome and to relate it to the antiretroviral regimen employed, to changes in lipid profile and to insulin resistance. METHODS: This was a cross-sectional study that evaluated 30 children and adolescents (median age = 9.1 years with the acquired immunodeficiency syndrome during 2004 and 2005. The following clinical and laboratory evaluations were performed: classification of HIV infection, anthropometric measurements (weight and height, serum glycemia, serum insulin and lipid profile (LDL-c, HDL-c, triglycerides. Lipodystrophy was diagnosed using clinical parameters. The chi-square test was used for statistical analysis. RESULTS: All of the patients were taking antiretroviral therapy regularly (median duration of 28.4 months; 80% were on three drugs in combination (highly active therapy and 30% were on protease inhibitors. Lipodystrophy and dyslipidemia were observed in 53.3 and 60% of the patients, respectively. Children on a highly active therapy regimen with protease inhibitors exhibited a higher percentage of mixed lipodystrophy; the difference between these children and the group on highly active therapy without protease inhibitors and the group not on a highly active therapy was statistically significant (44.4 vs. 16.7%; p = 0.004. There was no statistically significant association between the presence of lipodystrophy and sex, age (> 10 years, changes to the lipid profile or insulin resistance. CONCLUSIONS: The elevated prevalence of dyslipidemia and lipodystrophy observed among children with acquired immunodeficiency syndrome, which exhibited a relationship with the antiretroviral regimen employed, may represent an increased risk for future complications, in particular cardiovascular problems.

    Full Text Available Comorbidities in human immunodeficiency virus infection are of great interest due to their association with unfavorable outcomes and failure of antiretroviral therapy. This study evaluated the prevalence of coinfection by human immunodeficiency virus and viral hepatitis in an endemic area for hepatitis B in the Western Amazon basin. Serological markers for hepatitis B virus, hepatitis C virus and hepatitis D virus were tested in a consecutive sample of all patients referred for treatment of human immunodeficiency virus or acquired immunodeficiency syndrome. The variables sex, age, origin and exposure category were obtained from medical records and from the sexually transmitted diseases and acquired immunodeficiency syndrome surveillance database. Among 704 subjects, the prevalence of chronic hepatitis B carriage was 6.4% and past infection 40.2%. The presence of hepatitis B was associated with birth in hyperendemic areas of the Amazon basin, male sex and illegal drug use. The overall prevalence of hepatitis C was 5% and was associated with illegal drug use. The prevalence of hepatitis B and C among human immunodeficiency virus or acquired immunodeficiency syndrome patients in the Western Amazon basin was lower than seen elsewhere and is probably associated with the local epidemiology of these viruses and the degree of overlap of their shared risk factors. An opportunity presents itself to evaluate the prevention of hepatitis C through harm reduction policies and hepatitis B through vaccination programs among human immunodeficiency virus or acquired immunodeficiency syndrome patients.Co-morbidades na infecção pelo vírus da imunodeficiência humana são de grande interesse devido à associação com desfechos desfavoráveis e falhas na terapia anti-retroviral.

The patient was admitted with fever, asthenia, nausea, diarrhea, and reduced urinary output. He was found to have anemia, thrombocytopenia and severe renal failure. Hemolytic uremic syndrome was diagnosed and he was started on plasmapheresis and hemodialysis. Serological tests were consistent with acute human immunodeficiency virus infection: the enzyme linked immunosorbent assay for human immunodeficiency virus was weakly positive, Western Blot test was negative and human immunodeficiency virus RNA quantification was positive, with > 1,000,000 copies/microl. After 4 daily treatment sessions, patient's clinical condition improved and hemoglobin, platelets, lactic dehydrogenase and renal function normalized.

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

    Sweet\\'s syndrome (SS), a rare reactive neutrophilic dermatosis, has been reported to occur in association with a variety of systemic disorders, categorized by von den Diesch into idiopathic, paraneoplastic, pregnancy and parainflammatory subgroups. The parainflammatory group has been well defined, and includes a wide spectrum of infectious triggers and disorders of immune dysregulation. To date, however, no cases of SS have been described in the context of common variable immunodeficiency (CVID). We report a case of paediatric-onset SS, previously reported as idiopathic, with a subsequent diagnosis of CVID.

METHODS: This is a qualitative and exploratory study; data were collected between July and November 2008, through interviews with five family members of children with AIDS, who were sheltered in an institution of support. RESULTS: The meaning of statements were coded and analyzed, resulting in three categories: experiencing the order, disorder and the organization of a family member of a child with AIDS; dialoguing with the assurance and doubt of disclosing the diagnosis to a child with AIDS; and, facing the limits of unknown, decadence, live and death. CONCLUSION: It was revealed that being a family member and caring for a child with AIDS, is a complex process that requires an understanding of multiple factors (such as: biological, psychological, social, spiritual, and the ones related to the disease and the patient and the attitude of caring focused on the human being - a unique being, complex and multidimensional.

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

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

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

    Full Text Available The introduction of highly active antiretroviral therapy (HAART for the treatment of acquired immunodeficiency syndrome (AIDS has resulted in greater survival of patients infected with the human immunodeficiency virus (HIV. However, the use of these drugs has been associated with lipodystrophic syndrome (LS, which is characterized by metabolic alterations (dyslipidemia, insulin resistance, diabetes, and lactic acidosis and abnormal corporal fat distribution. Clinically, LS may manifest as three different forms: lipohipertrophy (accumulation of fat in the central part of the body, lipoatrophy (loss of fat in the extremities, face and buttocks and mixed (lipohipertrophy + lipoatrophy. Although its physiopathology has not been elucidated, some mechanisms have been described, including leptin and adiponectin deficiency, mitochondrial dysfunction and use of antiretroviral drugs. The type, dose and duration of the antiretroviral treatment, as well as age and puberty are the main risk factors. LS is also associated with increased incidence of cardiovascular illnesses, atherosclerosis and diabetes mellitus. Treatment includes physical activity, cautious restriction of caloric intake, changes in antiretroviral therapy, and use of insulin-sensitizing and lipid-lowering agents. Follow up must be periodic, consisting of measurement of body fat distribution, evaluation of the lipid profile and insulin resistance.

    Full Text Available Artemis, DNA ligase IV, DNA protein kinase catalytic subunit, and Cernunnos/XLF genes in nonhomologous end joining pathways of DNA repair mechanisms have been identified as responsible for radiosensitive SCID. Here, we present a 3-year-old girl patient with severe growth retardation, bird-like face, recurrent perianal abscess, pancytopenia, and polydactyly. Firstly, she was thought as Fanconi anemia and spontaneous DNA breaks were seen on chromosomal analysis. After that DEB test was found to be normal and Fanconi anemia was excluded. Because of that she had low IgG and IgA levels, normal IgM level, and absence of B cells in peripheral blood; she was considered as primary immunodeficiency, Nijmegen breakage syndrome. A mutation in NBS1 gene was not found; then Cernunnos/XLF deficiency was investigated due to clinical similarities with previously reported cases. Homozygous mutation in Cernunnos/XLF gene (NHEJ1 was identified. She is now on regular IVIG prophylaxis and has no new infection. Fully matched donor screening is in progress for bone marrow transplantation which is curative treatment of the disease. In conclusion, the patients with microcephaly, bird-like face, and severe growth retardation should be evaluated for hypogammaglobulinemia and primary immunodeficiency diseases.

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

    Brown syndrome is a rare strabismic disease characterized by a limited elevation in adduction of the eye. The lengthening/weakening of superior oblique muscle is the main way of surgical intervention for this disease. A 7-year-old boy was diagnosed as having acquired Brown syndrome in his right eye after injury in his face. We experienced successful release of this Brown syndrome through mere pulling outward of superior oblique tendon during surgical exploration. We briefly discuss why this manipulation of superior oblique tendon that we performed was successful.

    Aim: To evaluate lung disease on chest radiography (CR), the relative frequency of CR abnormalities, and their clinical correlates in adolescents with vertically-acquired human immunodeficiency virus (HIV) infection. Materials and methods: CRs of 75 patients [59 inpatients (33 males; mean age 13.7 {+-} 2.3 years) and 16 outpatients (eight males; mean age 14.1 {+-} 2.1 years)] were retrospectively reviewed by three independent observers. The overall extent of disease (to the nearest 5%), its distribution, and the proportional extents (totalling 100%) of different radiographic patterns (including ring/tramline opacities and consolidation) were quantified. CR features and clinical data were compared. Results: CRs were abnormal in 51/75 (68%) with 'extensive' disease in 38/51 (74%). Ring/tramline opacities and consolidation predominated (i.e., proportional extent >50%) in 26 and 21 patients, respectively. Consolidation was significantly more common in patients hospitalized primarily for a respiratory illness than patients hospitalized for a non-respiratory illness or in outpatients (p < 0.005, {chi}{sup 2} for trend); by contrast, ring/tramline opacities did not differ in prevalence across the groups. On stepwise logistic regression, predominant consolidation was associated with progressive dyspnoea [odds ratio (OR) 5.60; 95% confidence intervals (CI): 1.60, 20.1; p < 0.01] and was associated with a primary respiratory cause for hospital admission (OR: 22.0; CI: 2.7, 181.1; p < 0.005). Ring/tramline opacities were equally prevalent in patients with and without chronic symptoms and in those admitted to hospital with respiratory and non-respiratory illness. Conclusion: In HIV-infected adolescents, evaluated in secondary practice, CR abnormalities are prevalent. The presence of ring/tramline opacities, believed to reflect chronic airway disease, is not linked chronic respiratory symptoms.

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

    Full Text Available Sexually transmitted infections (STIs are more dynamic than other infections prevailing in the community. It is important that such dynamic epidemiological changes in STIs are acknowledged and kept track of in a vast and populous developing country like India, particularly in this HIV era. It is with this aim that the authors have reviewed the relevant literature in STI epidemiology in India during the past 25 years. Admittedly, there has been heterogeneity of data to account for the subcontinental dimension of this country. But a basic pattern in the changing epidemiology is discernible. Like the developed countries, in India too the bacterial STIs like chancroid and gonorrhea are declining, while viral STIs like HPV and herpes genitalis are on an upswing. The overall decline in the prevalence of STIs has to be interpreted with caution, however. This may partially reflect the improved facilities of treatment in the peripheral centres that obviates the need of many patients in attending the STD clinics in the tertiary centres. Also, the improved pharmacotherapy of many of the bacterial STIs may result in partial clearance and non-reporting of many of these infections.

    Full Text Available Aims and Objectives : To assess the prevalence of metabolic syndrome (MetS in human immunodeficiency virus (HIV positive patients. Prevalence of MetS was compared in patients who were not on highly active antiretroviral therapy (HAART to patients who were on HAART. Materials and Methods: Seventy HIV positive cases were studied. Pregnant and lactating women, patients on drugs other than HAART known to cause metabolic abnormalities and those having diabetes or hypertension were excluded. Cases were evaluated for MetS by using National Cholesterol Education Program Adult Treatment Panel-III. Results: 47 cases were on HAART and 23 cases were not on HAART. Fasting Blood Glucose ≥100 mg/dl was present in 28.6% cases, out of whom 27.7% were on HAART and 30.4% were not on HAART (P = 0.8089. 12.9% cases had BP ≥130/≥85 mm Hg, out of whom 14.9% were on HAART and 8.7% were not on HAART (P = 0.4666. 42.9% cases had TG ≥150 mg/dl, out of whom 44.7% were on HAART and 39.1% were not on HAART (P = 0.6894. HDL cholesterol was low (males <40 mg/dl, females <50 mg/dl in 50% cases, out of whom 55.3% were on HAART and 39.1% were not on HAART (P = 0.2035. Conclusions: Prevalence of MetS was 20%. Majority of patients had only one component of MetS (32.9%. Low HDL was present in 50%, followed by raised triglycerides in 42.9%. Waist circumference was not increased in any of the patients. There was no statistically significant difference between those on HAART and those not on HAART in distribution of risk factors and individual components of MetS.

    Hemophagocytic lymphohistiocytosis is a hyperinflammatory syndrome defined by clinical and laboratory criteria. Current criteria were created to identify patients with familial hemophagocytic lmyphohistiocytosis in immediate need of immunosuppressive therapy. However, these criteria also identify patients with infection-associated hemophagocytic inflammatory states lacking genetic defects typically predisposing to hemophagocytic lymphohistiocytosis. These patients include those with primary immunodeficiencies, in whom the pathogenesis of the inflammatory syndrome may be distinctive and aggressive immunosuppression is contraindicated. To better characterize hemophagocytic inflammation associated with immunodeficiencies, we combined an international survey with a literature search and identified 63 patients with primary immunodeficiencies other than cytotoxicity defects or X-linked lymphoproliferative disorders, presenting with conditions fulfilling current criteria for hemophagocytic lymphohistiocytosis. Twelve patients had severe combined immunodeficiency with immunodeficiencies; (ii) this syndrome can develop despite severe deficiency of T and NK cells, implying that the pathophysiology is distinct and not appropriately described as "lympho"-histiocytosis in these patients; and (iii) current criteria for hemophagocytoc lymphohistiocytosis are insufficient to differentiate hemophagocytic inflammatory syndromes with different pathogeneses. This is important because of implications for therapy, in particular for protocols targeting T cells.

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

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

    Full Text Available Acute febrile neutrophilic dermatosis (AFND, commonly known as Sweet’s syndrome, is a disorder seen in adult females, being extremely rare in children. Typical features include spiky fever, sudden eruption of raised painful erythematous to plum-colored nodules and plaques, neutrophilic leucocytosis, a dermal neutrophili infiltrate an a rapid response to systemic steroid. The eruption is believed to represent a hypersensitivity reaction to an antecedent infection or malignancy. There have been rare reports of acquired cutis laxa (Marshall’s syndrome following Sweet’s syndrome. We report one such case of Sweet’s syndrome leading to acquired cutis laxa (Marshall’ syndrome in a child.

    2016-12-01

    Fanconi syndrome (FS) is well described in humans and dogs, but has not been reported in cats. This case series describes four cats with acquired FS. On the basis of clinical signs and intestinal biopsies, all cats were initially diagnosed with alimentary lymphoma or inflammatory bowel disease. Treatment with chlorambucil and corticosteroids was started at standard doses, based on published protocols. Within 2-26 months of the start of treatment, glucosuria, despite normoglycemia, was identified incidentally on routine biochemical screening; FS was diagnosed with urine metabolic assays, confirming aminoaciduria and glucosuria in all four cases. Neither polyuria nor polydipsia were noted in any case, and only 1/4 cats had any clinical signs at the time of diagnosis. Partial or complete resolution of FS was seen in 3/4 cases within 3 months of discontinuing chlorambucil therapy. This is the first case series to document acquired FS in the cat, and the first to suggest a possible association between chlorambucil and acquired FS. Cats treated with chlorambucil should be monitored for the development of glucosuria, and discontinuation of chlorambucil should be considered if FS is identified. Further study into the association between chlorambucil and acquired FS in cats is warranted. © The Author(s) 2015.

    2014-12-01

    Full Text Available Acquired long QT syndrome results from secondary causes and can be caused by more than 100 non-antiarrhythmic drugs. Cardiac arrest due to Torsades de pointes induced by drugs causing prolonged QT syndrome is a rare but potentially fatal event, even in hospitals. The case of a 47-year-old patient diagnosed with non-Hodgkin lymphoma admitted to the hematology department of the Dr. Gustavo Aldereguía Lima University General Hospital in Cienfuegos is presented. The patient had been previously treated with anthracyclines and developed episodes of palpitations and syncope later. The treatment included monitoring the patient, avoiding other QT prolonging agents and administrating magnesium sulfate and potassium chloride with a proper maintenance of the fluid and acid-base balance. The presentation of this case aims at motivating interest in new reports on the subject and establishing a direct causal relationship through the evidence provided by new experiences.

    Some patients found to have clonal panmyelopathies develop an acquired defect of haemoglobin synthesis clinically similar to haemoglobin H disease. A 58 year-old male diagnosed of simple refractory anaemia developed microcytosis and hypochromia. At the same time, his myelodysplastic syndrome became a refractory anaemia with excess of blasts. 33% of the red blood cells had "golf ball" inclusions after incubation with brilliant cresyl blue. Cellulose acetate electrophoresis revealed an haemoglobin H band. The globin chain synthesis alpha/beta ratio was 0.69. The molecular analysis demonstrated the integrity of both alpha genes in each chromosome. There were no familiar antecedent of haemoglobinopathy.

    2015-01-01

    Full Text Available Rapadilino syndrome is a genetic disease characterized by a characteristic clinical tableau. It is caused by mutations in RECQL4 gene. Immunodeficiency is not described as a classical feature of the disease. We present a 2-year-old girl with Rapadilino syndrome with important lymphadenopathies and pneumonia due to disseminated Mycobacterium lentiflavum infection. An immunological work-up showed several unexpected abnormalities. Repeated blood samples showed severe lymphopenia. Immunophenotyping showed low T, B, and NK cells. No Treg cells were seen. T cell responses to stimulations were insufficient. The IL12/IL23 interferon gamma pathway was normal. Gamma globulin levels and vaccination responses were low. With this report, we aim to stress the importance of screening immunodeficiency in patients with RECQL4 mutations for immunodeficiency and the need to further research into its physiopathology.

    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.

    Full Text Available Context: Acquired von Willebrand syndrome (AVWS is a rare bleeding disorder that mimics the inherited form of von Willebrand disease (VWD in terms of laboratory findings and clinical presentation. Aims: To study the etiology of acquired VWD. Settings and Design: The patients referred from various hospitals in and out of Mumbai were included in the study. Materials and Methods: Six patients with AVWS diagnosed at this center over the last 10 years were analyzed against 171 patients with inherited VWD. The differential diagnosis of AVWS was made based on reduced levels of von Willebrand antigen and von Willebrand ristocetin cofactor, decrease in ristocetin induced platelet aggregation, absence of correction in mixing studies with no prior history of bleeding problems and a negative family history for bleeding disorders. Results: In three patients, the disease was associated with systematic lupus erythematosus, out of which one was also associated with Kikuchi lymphadenitis and second with autoimmune hemolytic anemia. Fourth case was associated with hypothyroidism and fifth was a case of dermatitis and vitiligo. The last patient was a case of hemophilia A with Burkitts lymphoma, who developed autoantibodies to von Willebrand factor. Except two patients, all other patients responded to immune suppressive therapy with corticosteroids, while the patient with hypothyroidism responded to oral thyroxine. Conclusion: AVWS is a rare condition and may often be missed or diagnosed as inherited disease associated with heterogeneous disease conditions.

    Full Text Available Abstract Introduction Few cases of Epstein-Barr virus myelitis have been described in the literature. Multi-centric Castleman's disease is a lymphoproliferative disorder that is well known for its associations with the human immunodeficiency virus, human herpes virus 8, and Kaposi's sarcoma. The concurrent presentation of these two diseases in a patient at the same time is extremely unusual. Case Presentation We describe the case of a 43-year-old Caucasian man with acquired immune deficiency syndrome who presented with fever, weight loss and diffuse lymphadenopathy, and was diagnosed with multi-centric Castleman's disease. He presented three weeks later with lower extremity weakness and urinary retention, at which time cerebrospinal fluid contained lymphocytic pleocytosis and elevated protein. Magnetic resonance imaging demonstrated abnormal spinal cord signal intensity over several cervical and thoracic segments, suggesting the diagnosis of myelitis. Our patient was ultimately diagnosed with Epstein-Barr virus myelitis, as Epstein-Barr virus DNA was detected by polymerase chain reaction in the cerebrospinal fluid. Conclusion To the best of our knowledge, this is the first case of multi-centric Castleman's disease followed by acute Epstein-Barr virus myelitis in a human immunodeficiency virus-infected patient. Clinicians caring for human immunodeficiency virus-infected patients should be vigilant about monitoring patients with increasing lymphadenopathy, prompting thorough diagnostic investigations when necessary.

  4. [Neural mechanism underlying autistic savant and acquired savant syndrome].

    It is well known that the cases with savant syndrome, demonstrate outstanding mental capability despite coexisting severe mental disabilities. In many cases, savant skills are characterized by its domain-specificity, enhanced memory capability, and excessive focus on low-level perceptual processing. In addition, impaired integrative cognitive processing such as social cognition or executive function, restricted interest, and compulsive repetition of the same act are observed in savant individuals. All these are significantly relevant to the behavioral characteristics observed in individuals with autistic spectrum disorders (ASD). A neurocognitive model of savant syndrome should explain these cognitive features and the juxtaposition of outstanding talents with cognitive disabilities. In recent neuropsychological studies, Miller (1998) reported clinical cases of "acquired savant," i.e., patients who improved or newly acquired an artistic savant-like skill in the early stage of frontotemporal dementia (FTD). Although the relationship between an autistic savant and acquired savant remains to be elucidated, the advent of neuroimaging study of ASD and the clarification of FTD patients with savant-like skills may clarify the shared neural mechanisms of both types of talent. In this review, we classified current cognitive models of savant syndrome into the following 3 categories. (1) A hypermnesic model that suggests that savant skills develop from existing or dormant cognitive functions such as memory. However, recent findings obtained through neuropsychological examinations imply that savant individuals solve problems using a strategy that is fairly different from a non-autistic one. (2) A paradoxical functional facilitation model (Kapur, 1996) that offers possible explanations about how pathological states in the brain lead to development of prodigious skills. This model emphasizes the role of reciprocal inhibitory interaction among adjacent or distant cortical regions

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

    As a major tourist attraction for heterosexuals and homosexuals, Thailand stands to experience major increases in the rate of acquired immunodeficiency syndrome (AIDS). This article describes 2 AIDS cases in Thailand, including the 1st documented case. The 1st case involved a 28-year-old unmarried Thai male who travelled to the US in 1981 for postgraduate work and had contact with both female prostitutes and homosexual men. In 1982-83, the patient demonstrated fever, fatigue, meningitis, and finally Pneumocystis carinii. He was hospitalized in 1984 for fever, bilateral deafness, and diarrhea. Serologic analysis revealed antibodies to human T-cell lymphotropic virus type III (HTLV- III). Death occurred in January 1985. The 2nd patient was a 52-year- old single man who had moved from West Germany to Thailand 10 years previously to admission in 1985 for upper gastrointestinal bleeding. The patient, a homosexual, make frequent visits to Germany and was an alcoholic. The initial clinical diagnosis was ruptured esophageal varices with cirrhosis. The patient further had a history of herpes simplex genitalis. The subsequent course of the disease process included massive blood loss and interstitial pneumonitis. Serology revealed antibodies to HTLV-III. Death occurred in August 1985. Both of these patients belonged to groups at high risk of AIDS and had clinical, serologic, and immunologic indicators that enabled confirmation of the AIDS diagnosis.

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

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

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

    Full Text Available Abstract Background PHACE is a neurocutaneous syndrome associated with: Posterior fossa brain malformations, large “segmental” facial hemangiomas, arterial cerebrovascular-, cardiovascular-, and eye anomalies. Case vignette We are reporting a girl with PHACE syndrome. The patient had a congenital right-sided facial hemangioma with plaque-morphology. At age 11 years and 2 months she presented with short stature, markedly decreased growth velocity and signs and symptoms suggestive of hypothyroidism. Magnetic Resonance Imaging (MRI of the brain revealed complex structural and cerebrovascular arterial anomalies, including an empty sella. Testing of pituitary function revealed multiple pituitary dysfunctions, including absolute growth hormone deficiency, hypogonadotropic hypogonadism, central hypothyroidism, and secondary adrenal insufficiency. Conclusions This case suggests the necessity to screen all patients with PHACE syndrome and intracranial malformations for pituitary dysfunction at regular intervals.

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

    Full Text Available Down syndrome (DS is caused by triplication of Human chromosome 21 (Hsa21 and associated with an array of deleterious phenotypes, including mental retardation, heart defects and immunodeficiency. Genome-wide expression patterns of uncultured peripheral blood cells are useful to understanding of DS-associated immune dysfunction. We used a Human Exon microarray to characterize gene expression in uncultured peripheral blood cells derived from DS individuals and age-matched controls from two age groups: neonate (N and child (C. A total of 174 transcript clusters (gene-level with eight located on Hsa21 in N group and 383 transcript clusters including 56 on Hsa21 in C group were significantly dysregulated in DS individuals. Microarray data were validated by quantitative polymerase chain reaction. Functional analysis revealed that the dysregulated genes in DS were significantly enriched in two and six KEGG pathways in N and C group, respectively. These pathways included leukocyte trans-endothelial migration, B cell receptor signaling pathway and primary immunodeficiency, etc., which causally implicated dysfunctional immunity in DS. Our results provided a comprehensive picture of gene expression patterns in DS at the two developmental stages and pointed towards candidate genes and molecular pathways potentially associated with the immune dysfunction in DS.

    Full Text Available Abstract Background Since it's recognition in 1981, a more complete phenotype of Kabuki syndrome is becoming evident as additional cases are identified. Congenital heart defects and a number of visceral abnormalities have been added to the typical dysmorphic features originally described. Case Report In this report we describe the clinical course of a child diagnosed with Kabuki syndrome based on characteristic clinical, radiological and morphologic features who died of a cardiac arrhythmia at 11-months of age. This infant, however, had abnormal pulmonary architecture and alterations in his cardiac conduction system resulting in episodes of bradycardia and asystole. This child also had an immunological phenotype consistent with common variable immunodeficiency. His clinical course consisted of numerous hospitalizations for recurrent bacterial infections and congenital hypogammaglobulinemia characterized by low serum IgG and IgA but normal IgM levels, and decreased antibody levels to immunizations. T-, B- and NK lymphocyte subpopulations and T-cell function studies were normal. Conclusion This child may represent a more severe phenotype of Kabuki syndrome. Recurrent infections in a child should prompt a thorough immunological evaluation. Additionally, electrophysiology testing may be indicated if cardiopulmonary events occur which are not explained by anatomic defects.

    Immunodeficiency, Centromeric Instability, Facial Anomalies (ICF) syndrome is a rare autosomal recessive disorder that is characterized by a marked immunodeficiency, severe hypomethylation of the classical satellites 2 and 3 associated with disruption of constitutive heterochromatin, and facial anomalies. Sixty percent of ICF patients have mutations in the DNMT3B (DNA methyltransferase 3B) gene, encoding a de novo DNA methyltransferase. In the present study, we have shown that, in ICF lymphoblasts and peripheral blood, juxtacentromeric heterochromatic genes undergo dramatic changes in DNA methylation, indicating that they are bona fide targets of the DNMT3B protein. DNA methylation in heterochromatic genes dropped from about 80% in normal cells to approximately 30% in ICF cells. Hypomethylation was observed in five ICF patients and was associated with activation of these silent genes. Although DNA hypomethylation occurred in all the analyzed heterochromatic genes and in all the ICF patients, gene expression was restricted to some genes, every patient having his own group of activated genes. Histone modifications were preserved in ICF patients. Heterochromatic genes were associated with histone modifications that are typical of inactive chromatin: they had low acetylation on H3 and H4 histones and were slightly enriched in H3K9Me3, both in ICF and controls. This was also the case for those heterochromatic genes that escaped silencing. This finding suggests that gene activation was not generalized to all the cells, but rather was restricted to a clonal cell population that may contribute to the phenotypic variability observed in ICF syndrome. A slight increase in H3K27 monomethylation was observed both in heterochromatin and active euchromatin in ICF patients; however, no correlation between this modification and activation of heterochromatic genes was found.

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

    Full Text Available OBJECTIVES: To compare epidemiological aspects of young (15 to 49 years old and older (more than 50 years old AIDS patients. METHODS: We analyzed 511,633 AIDS cases notified to the Brazilian Ministry of Health in the period of 1980-2008 looking at sex, age ranges, educational level and exposure category. Patients were divided into three age groups: under 15, from 15 to 49 and over 50 years old. Using a comparative approach, we analyzed data with regard to category of exposure, education (expressed in years of schooling, and sex ratio among younger (15-49 and older adults (over 50 years old. Time series data were log-transformed and normalized, and the temporal trend was evaluated. RESULTS: AIDS incidence is increasing among people over 50 years old in Brazil, with those older than 50 being responsible for 9.64 % of AIDS cases. There was no significant difference between educational level and gender (p = 0.468, but there was a significant difference in exposure category with a lower proportion of injecting drug users amongst the older group. CONCLUSION: Based on this analysis over the last 10 years, the percentage of AIDS cases has increased almost three times among people over 50 years old when compared with the 15-49 year-old group. Our findings suggest that public campaigns have to be specially targeted to the older segment of the population, aiming at heterosexual transmission.

    Lung diseases are frequently observed in individuals infected with HIV. The aim of this study was to identify infectious agents in the lungs in the autopsied individuals with AIDS performed between march 1990 and july 2000 at the school of medicine (Uberaba- Brazil), using histochemical and immunohistochemical techniques. Analysis was made on lungs obtained from 40 individuals with AIDS. Infectious agents were observed in 34 (85%) cases of the 40 analyzed. Regarding fungis, Pneumocystis carinii was found in 8 (19.1%)cases; Cryptococcus sp in 4 (9.5%)cases, Histoplasma sp in 2 (4.8%)cases and Candida sp in 1 (2.4%)case. Association of Pneumocystis carinii, Citomegalovirus and Cryptococcus sp, was observed in one case, and in another, the association of CMV, and Toxoplasma gondii. There were 5 cases with Candida sp, CMV and Pneumocystis carinii associated with bacteria. In conclusion, this study shows that following bacterial agents fungi were the second most common infectious agents in post mortem examination of the lungs from patients with AIDS, being Pneumocystis carinii the most prevalent.

    PURPOSE: To evaluate and delineate the characteristics of cerebral toxoplasmosis lesions using a combination of magnetic resonance (MR) spectroscopy, diffusion, and perfusion studies. MATERIAL AND METHODS: A total of 8 patients with 23 lesions were evaluated on a 1.5-T MR system. Diffusion-weighted imaging (DWI) was performed with three 'b' values of 50, 500, and 1000 s/mm2, and the apparent diffusion coefficient maps were calculated. The diffusion-weighted appearances and the T2-weighted MR appearances of the lesions were compared. MR spectroscopy was performed using the point-resolved single-voxel technique with two TE values of 135 ms and 270 ms. Perfusion studies were carried out using the dynamic contrast-enhanced technique, and the relative cerebral blood volume maps were qualitatively and quantitatively analyzed. RESULTS: DWI revealed the majority of the lesions as having increased diffusion within their necrotic centers, with the ADC ranging from 0.5 to 3.01 (mean {+-} SD: 1.49 {+-} 0.7). All the lesions revealed a predominant lipid peak on MR spectroscopy and were extremely hypovascular on perfusion MR studies. CONCLUSION: MR diffusion, spectroscopy, and perfusion studies help in characterizing toxoplasmosis lesions and, in most cases, can be used in combination to help establish the diagnosis of toxoplasmosis.

    Full Text Available Bioethical aspects related with the prevention, diagnosis and treatment of patients with AIDS are present in the Cuban strategy to fight the epidemic. Through the revision of the essentials and principles of Bioethics, we analyze the problems that doctors face when treating these patients and aspects related with education for health in the case of this disease. It also outlines the association between these principles and the disposition, manifested or not, of theses patients to be part of some researches. This infection should be the target of permanent analysis by the Bioethics due to the constant challenges that it represent for medical staff and for society, either for the prevention, treatment and care, or for other kids of actions. Cuba has exceptional results in this field.

El objetivo del trabajo fue evaluar la respuesta antitumoral de la preparación de una formulación de cisplatino en 3 pacientes con HIV y CEC recidivante, candidatos a tratamiento de enucleación y exenteración orbitaria, y evaluar los efectos adversos que se presentaron con la administración de la formulación aplicada. Métodos: fueron tratados 3 pacientes masculinos, caucásicos, con media de edad 37 años, a los que se les realizó cirugía exerética y se les administraron 3 ciclos de quimioterapia subconjuntival, con duración de 3 meses. Resultados: todos los pacientes conservaron sus ojos y la visión. No hubo persistencia ni aparecieron recidivas tumorales durante el periodo evaluado. Un paciente falleció por progresión del HIV 2 años después de finalizado el tratamiento, mantuvo visión conservada y sin actividad tumoral. Conclusión: el tratamiento con quimioterapia subconjuntival adyuvante a la cirugía resulta eficaz y es tolerable en la población de pacientes tratados.

    We report a series of thirteen patients with nervous system complications out of a total of thirty AIDS patients admitted to our hospital over the last two years for which CT and/or MRI have been performed. Five were homosexual men and eight patients (5 men, 3 women) were of African origin (Zaire and Rwanda) (n=5) or had had sexual intercourse with the local African population (n=3). The nervous system complications encountered included: Toxoplasma gondii brain abscess (2 patients); cryptococcus neoformans meningitis+toxoplasmosis (1 patient); toxoplasmosis+lymphoma (2 patients); progressive multifocal leucoencephalopathy (1 patient); lymphocytic meningitis or encephalitis (3 patients); lymphoma (1 patient); polyradiculoneuritis (3 patients). Three of thirteen patients had multiple intracranial abnormalities: One had concomitant intraparenchymal toxoplasma abscess and cryptococcal meningitis; in one patient a lymphoma developed after the successful medical treatment of a toxoplasma abscess; conversely, one patient developed a toxoplasma abscess two years after mediastinal radiotherapy for a systemic non-Hodgkin lymphoma. In conclusion, in our experience, nervous system toxoplasmosis is the most frequent AIDS related CNS complication. Our series demonstrates the high frequency of a second neurological disease occurring either concomitantly or separately. In these cases, while CT may readily identify the intracranial abnormalities, it contributes little towards an etiological diagnosis. Finally, our series illustrates the importance of a central African endemic focus for AIDS.

    The mechanisms of chronic infestation by Strongyloides stercoralis (Ss) are unknown. Immunodepression is classically evoked to explain the proliferation of the parasite that is sometimes massive and overwhelming. We present here two retrospective studies of 13 cases of strongyloidiasis (three disseminated strongyloidiasis) out of 26 patients with adult T-cell leukemia/lymphoma (ATL) and of ten cases of strongyloidiasis out of 98 patients with AIDS. Ten patients out of 98 were dually infected with both HIV and HTLV-1: 2/10 also infected by Ss. The frequency of Ss infection appears higher in ATL patients when compared with AIDS patients (P AIDS patients were older than the ones uninfected (p difference was found between ATL and AIDS patients who were over 40 years-old. These data suggest that 1) the particular type of immunodepression produced early by HTLV-1 is more favorable to the development of Ss infection than the one associated with HIV, 2) the latency of expression of HTLV-1, prior to the development of leukemia, is reduced in Ss-infected patients, 3) Ss infection may slow down VIH pathogenic activity.

    To investigate the clinical features, therapeutic approaches, outcomes and alterations of peripheral lymphocytes subsets in cytomegalovirus (CMV) infections in patients with AIDS. Ninety-six cases of AIDS were treated in Peking Union Medical College Hospital and 23 of them had CMV infection. We analyzed the clinical features, peripheral lymphocytes subsets, outcomes, CMV pp65 antigen and/or specific anti-CMV IgM. In the 23 CMV patients, nonspecific symptoms including fever, cough, chest distress and diarrhea occurred in 18, 11, 9 and 8 patients, respectively. Thirteen patients had retinitis identified by ophthalmofundoscopy, 7 of them had blurred vision or floating as primary symptoms. Pneumocystis pneumonia, tuberculosis infection and other infection appeared in 18 patients. Fifteen (65.2%) of the patients had positive serum tests. The positive rates for CMV pp65 and specific anti-CMV-IgM were 43.5% and 30.4%, respectively. CD(4)(+)T cell count in CMV patients was remarkably decreased than that in non-CMV patients [14(4, 39) cells/microl vs (48(12, 128) cells/microl, P = 0.005] and the proportion of CD(8)(+)CD(38)(+)T cells in CMV patients was higher than that in non-CMV patients, whereas the difference of CD(8)(+)T cell was not statistically different between the 2 groups. CMV infection often occurs in advanced AIDS patients. In HIV/AIDS patients with CD(4)(+)T cell count AIDS should be considered.

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

    Computed tomography (CT) delineates the presence or absence of intracerebral focal lesions in most instances. The presence of contrast enhancement, cerebral atrophy, and an intracranial mass are important in consideration of the differential diagnosis and in establishing the diagnosis. Initially the authors utilized a double dose of contrast medium in all patients after single-dose study, but little additional information was obtained. A second dose of contrast medium is now administered only to evaluate further a suspected lesion. Angiography can confirm the location of the lesion(s) and the cortical veins before biopsy. Of one hundred patients with AIDS examined, 33% had neurological symptoms excluding headache and herpes zoster. All patients with neurological symptoms were studied with noncontrast and contrast CT scanning. Twenty-seven patients in the group had abnormal scans. In 13, the abnormality was limited to a diffuse atrophic appearance, while in 14, focal lesions were identified. Representative cases are discussed and illustrated.

    Full Text Available BACKGROUND: Brazil's National STD/AIDS Program is considered a model of success worldwide. However, AIDS-associated malnutrition continues in subgroups of Brazilian patients despite access to free highly active antiretroviral therapy (HAART. We aimed to identify the prevalence of malnutrition and associated factors among patients hospitalized with AIDS. METHODS: We conducted a cross-sectional nutritional assessment among 127 adults hospitalized with AIDS in Brazil's third largest city. Using anthropometric measurements, we determined the prevalence of malnutrition (body mass index <18.5 kg/m2 at hospitalization. Prevalence ratios of malnutrition by demographic, socioeconomic, and clinical conditions were estimated using log-binomial regression. RESULTS: One-third of participants were first informed of their HIV disease during the current hospitalization and recent treatment interruption was common (71% among those on HAART. Forty-three percent were malnourished and 35% had severe weight loss at admission. Patient characteristics independently associated with malnutrition were older age (2% increased prevalence for each year; 95% confidence interval [CI] 0-4% and very low daily per capita household income.

    Zidovudine (azidothymidine, AZT) disposition was examined during a hemodialysis session in an HIV-infected male with mesangial proliferative glomerulonephritis. Serum concentrations of zidovudine and its glucuronidated inactive metabolite (G-ZDV) were measured by HPLC. Zidovudine pharmacokinetics were similar to previous reports in patients with normal renal function, however, G-ZDV concentrations were significantly elevated (23-440 times zidovudine concentration). Hemodialysis did not appreciably reduce zidovudine or G-ZDV levels. Significance of chronically elevated G-ZDV levels is unknown.

    We report a case of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) concomitant with acquired von Willebrand syndrome. A 33-year-old man developed motor and sensory polyneuropathy with electrophysiological conduction slowing. At this time, M-protein was absent He was diagnosed with CIDP and received intravenous immunoglobulin and subsequent oral corticosteroids, which resulted in almost complete remission for over 10 years. At the age of 44, he presented with chronic anemia. Laboratory tests and colonoscopy revealed that he had acquired von Willebrand syndrome with monoclonal gammopathy of undetermined significance (IgG lambda type) and colon cancer. Bleeding symptoms were.resolved with intravenous immunoglobulin, but not with supplementation of factor VIII. Shortly after successful excision of the cancer, CIDP and acquired von Willebrand syndrome simultaneously recurred. Intravenous immunoglobulin produced rapid improvement of both neurological and hematological abnormalities. Concurring CIDP and acquired von Willebrand syndrome in the present case may indicate that the conditions have a partly common immunological background including monoclonal gammopathy and a potential common autoantibody-mediated mechanism. Alternatively, dysfunction of von Willebrand factor may increase blood-nerve barrier permeability, inducing the recurrence of CIDP.

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

  6. Identification of a mutation associated with fatal Foal Immunodeficiency Syndrome in the Fell and Dales pony.

    Directory of Open Access Journals (Sweden)

    Laura Y Fox-Clipsham

    2011-07-01

    Full Text Available The Fell and Dales are rare native UK pony breeds at risk due to falling numbers, in-breeding, and inherited disease. Specifically, the lethal Mendelian recessive disease Foal Immunodeficiency Syndrome (FIS, which manifests as B-lymphocyte immunodeficiency and progressive anemia, is a substantial threat. A significant percentage (∼10% of the Fell ponies born each year dies from FIS, compromising the long-term survival of this breed. Moreover, the likely spread of FIS into other breeds is of major concern. Indeed, FIS was identified in the Dales pony, a related breed, during the course of this work. Using a stepwise approach comprising linkage and homozygosity mapping followed by haplotype analysis, we mapped the mutation using 14 FIS-affected, 17 obligate carriers, and 10 adults of unknown carrier status to a ∼1 Mb region (29.8 - 30.8 Mb on chromosome (ECA 26. A subsequent genome-wide association study identified two SNPs on ECA26 that showed genome-wide significance after Bonferroni correction for multiple testing: BIEC2-692674 at 29.804 Mb and BIEC2-693138 at 32.19 Mb. The associated region spanned 2.6 Mb from ∼29.6 Mb to 32.2 Mb on ECA26. Re-sequencing of this region identified a mutation in the sodium/myo-inositol cotransporter gene (SLC5A3; this causes a P446L substitution in the protein. This gene plays a crucial role in the regulatory response to osmotic stress that is essential in many tissues including lymphoid tissues and during early embryonic development. We propose that the amino acid substitution we identify here alters the function of SLC5A3, leading to erythropoiesis failure and compromise of the immune system. FIS is of significant biological interest as it is unique and is caused by a gene not previously associated with a mammalian disease. Having identified the associated gene, we are now able to eradicate FIS from equine populations by informed selective breeding.

    2017-01-01

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

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

    A pilot project, ¿Youth Inform¿ endorsed by the Ministry of Health and Ministry of Education, Singapore, was undertaken in 1992 for 2 years. It aims to enhance sexually transmitted disease (STDs)/human immunodeficiency virus (HIV) control in Singapore by providing structured information for young people between the ages of 16 to 20 years in Polytechnics, Junior Colleges, Centralised Institutes and Pre-University Centres. Project Youth Inform comprises 8 components. They include a focus group discussion, a training seminar for teachers, a lecture/slide presentation cum question-and-answer session, an educational booklet/bookmark, exhibitions, a video, provisions for anonymous questions, and an evaluation. The programme is conducted during school hours at the premises of the institutions and the attendance per session is between 150 to 350 students. A total of 152 sessions have been completed for all the schools. It is ongoing and is currently administered by the School Health Service and Training and Health Education Department. Feedback from principals, teachers and students was gathered formally through surveys and informally through interviews and observations. One thousand students were randomly selected for the survey to assess their responses towards the programme. Eighty-six percent reported that they found it educational and informative. Indicators found to have an influence on the effectiveness of the programme were timing, vocabulary used (medical terms) and integration of the programme into the school's curriculum. In conclusion, Project Youth Inform was on the whole positively received. However, it is essential to constantly accommodate and adapt to new facts and methods of teaching and maintain close coordination with the Ministries and the schools. An effective STD/acquired immune deficiency syndrome programme is an important step towards the prevention, management and control of the epidemic.

    Elastic fibers in the extracellular matrix are an integral component of dermal connective tissue. The resilience and elasticity required for normal structure and function of the skin may be attributed to the network of elastic tissue. Advances in our understanding of elastic tissue physiology provide a foundation for studying the pathogenesis of elastic tissue disorders. Many acquired disorders are nevertheless poorly understood due to the paucity of reported cases. Several acquired disorders in which accumulation or elastotic degeneration of dermal elastic fibers produces prominent clinical and histopathologic features have recently been described. They include elastoderma, linear focal elastosis, and late-onset focal dermal elastosis and must be differentiated from better-known disorders, among them acquired pseudoxanthoma elasticum, elastosis perforans serpiginosa, and Favré-Racouchot syndrome. Learning objective At the conclusion of this learning activity, participants should understand the similarities and differences between acquired disorders of elastic tissue that are characterized by an increase in elastic tissue, as well as the spectrum of solar elastotic dermatoses.

    Horner syndrome, a triad of ptosis, anisocoria, and anhidrosis, results from interruption in the oculosympathetic pathway. It is classically described as either congenital or acquired to depict its underlying pathophysiology and requisite work-up. We report a case of a 10-month-old infant presenting with an acute onset of left Horner syndrome secondary to a spontaneous extracranial internal carotid artery dissection. To the best of our knowledge, this is the first case report in the literature of acute onset of acquired infantile Horner syndrome in association with spontaneous carotid artery dissection confirmed with magnetic resonance angiogram.

    Almost a decade into the epidemic of acquired immunodeficiency syndrome (AIDS) there is adequate evidence to address the concerns of dental staff about possible transmission of human immunodeficiency virus (HIV) between patient and staff. This paper reviews that evidence and demonstrates that the risk of HIV transmission to health care workers is extremely low. Worldwide there are no reported proven cases of occupational transmission of HIV to dental staff.

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

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

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

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

    Two hundred six dental patients were tested between 1985 and 1987 for antibodies to human immunodeficiency virus (HIV) when a review of their medical histories revealed a high risk for infection. Serologic results are correlated with soft tissue and osseous findings recorded during routine head and neck and radiographic examination. Counseling recommendations for use in association with testing are outlined. A more active role for the dentist as a preventive agent is advocated to combat the spread of acquired immunodeficiency syndrome (AIDS).

    Mutations in the SP110 gene result in infantile onset of the autosomal recessive primary immunodeficiency disease veno-occlusive disease with immunodeficiency syndrome (VODI), which is characterized by hypogammaglobulinemia, T-cell dysfunction, and a high frequency of hepatic veno-occlusive disease. We sought to further characterize the clinical features, B-lineage cellular immunologic findings, and molecular pathogenesis of this disorder in 9 patients with new diagnoses, including 4 novel mutations from families of Italian, Hispanic, and Arabic ethnic origin. Methods used include clinical review; Sanger DNA sequencing of the SP110 gene; determination of transfected mutant protein function by using immunofluorescent studies in Hep-2 cells; quantitation of B-cell subsets by means of flow cytometry; assessments of B-cell function after stimulation with CD40 ligand, IL-21, or both; and differential gene expression array studies of EBV-transformed B cells. We confirm the major diagnostic criteria and the clinical utility of SP110 mutation testing for the diagnosis of VODI. Analysis of 4 new alleles confirms that VODI is caused by reduced functional SP110 protein levels. Detailed B-cell immunophenotyping demonstrated that Sp110 deficiency compromises the ability of human B cells to respond to T cell-dependent stimuli and differentiate into immunoglobulin-secreting cells in vitro. Expression microarray studies have identified pathways involved in B-lymphocyte differentiation and macrophage function. These studies show that a range of mutations in SP110 that cause decreased SP110 protein levels and impaired late B-cell differentiation cause VODI and that the condition is not restricted to the Lebanese population.

    Epileptic encephalopathies with continuous spike-and-waves during sleep (CSWS) are characterized by cognitive or language impairment, and are occasionally associated with pathogenic variants of the GRIN2A gene. In these disorders, speech dysfunction could be either related to cerebral dysfunction caused by the GRIN2A deleterious variant or intense interictal epileptic activity. Here, we present a patient with apraxia of speech, clearly linked to severity of epilepsy, carrying a GRIN2A variant. A 6-year-old boy developed acute regression of expressive language following epileptic seizures, leading to complete mutism, at which time EEG revealed CSWS. MEG showed bilateral superior parietal and opercular independent CSWS onsets and PET with fluorodeoxyglucose demonstrated significant increase in relative glucose metabolism in bilateral superior parietal regions. Corticosteroids induced a regression of CSWS together with impressive improvement in speech abilities. This case supports the hypothesis of a triggering role for epileptic discharges in speech deterioration observed in children carrying a deleterious variant of GRIN2A. When classic antiepileptic drugs fail to control epileptic activity, corticosteroids should be considered. Multimodal functional neuroimaging suggests a role for opercular and superior parietal areas in acquired epileptic opercular syndrome. [Published with video sequences on www.epilepticdisorders.com].

    Cryptococcal meningitis (CM) is a central nervous system infectious disease caused by Cryptococcus. It is the most common fungal infection in the central nervous system, accounting for about 48% of fungal infection. The disease occurs mainly in acquired immunodeifciency syndrome (AIDS) patients and concentrates in the immunocompromised people without AIDS. There are nearly one million new cases of CM each year, and about 70% of them died. In China, CM occurs mainly in people without AIDS and there is an increasing trend in recent years. Early diagnosis and treatment is the key to reducing morbidity and mortality associated with CM. The diagnosis mainly depends on laboratory examination such as morphological examination, fungal culture and antigen detection. History, clinical manifestation and imaging examination are the important parts of auxiliary examination. The initial combined antifungal treatment is emphasized, and the principle of fractional treatment including induction, consolidation and maintenance therapy should be followed. The high intracranial pressure must be reduced actively at the same time. In addition, it is proved that the novel immunotherapy combined with antifungal agents can improve the curative effect and limit the chance of antimicrobial resistance. Large-scale clinical trials are needed for further study.

  14. Selective acquired long QT syndrome (saLQTS upon risperidone treatment

    Directory of Open Access Journals (Sweden)

    Lazarczyk Maciej

    2012-12-01

    Full Text Available Abstract Background Numerous structurally unrelated drugs, including antipsychotics, can prolong QT interval and trigger the acquired long QT syndrome (aLQTS. All of them are thought to act at the level of KCNH2, a subunit of the potassium channel. Although the QT-prolonging drugs are proscribed in the subjects with aLQTS, the individual response to diverse QT-prolonging drugs may vary substantially. Case presentation We report here a case of aLQTS in response to small doses of risperidone that was confirmed at three independent drug challenges in the absence of other QT-prolonging drugs. On the other hand, the patient did not respond with QT prolongation to some other antipsychotics. In particular, the administration of clozapine, known to be associated with higher QT-prolongation risk than risperidone, had no effect on QT-length. A detailed genetic analysis revealed no mutations or polymorphisms in KCNH2, KCNE1, KCNE2, SCN5A and KCNQ1 genes. Conclusions Our observation suggests that some patients may display a selective aLQTS to a single antipsychotic, without a potassium channel-related genetic substrate. Contrasting with the idea of a common target of the aLQTS-triggerring drugs, our data suggests existence of an alternative target protein, which unlike the KCNH2 would be drug-selective.

    Full Text Available Abstract Introduction Hypereosinophilic syndrome is defined as a prolonged state (more than six months of eosinophilia (greater than 1500 cells/μL, without an apparent etiology and with end-organ damage. Hypereosinophilic syndrome can cause coagulation abnormalities. Among hypereosinophilic syndrome types, the lymphocytic variant (lymphocytic hypereosinophilic syndrome is derived from a monoclonal proliferation of T lymphocytes. Here, we describe the case of a patient with lymphocytic hypereosinophilic syndrome who presented with a coagulation abnormality. To the best of our knowledge, this is the first such report including a detailed clinical picture and temporal cytokine profile. Case presentation A 77-year-old Japanese man presented to our facility with massive hematuria and hypereosinophilia (greater than 2600 cells/μl. His eosinophilia first appeared five years earlier when he developed femoral artery occlusion. He manifested with multiple hematomas and prolonged activated partial thromboplastin time. His IgG4 level was remarkably elevated (greater than 2000 mg/dL. Polymerase chain reaction tests of peripheral blood and bone marrow identified lymphocytic hypereosinophilic syndrome. His prolonged activated partial thromboplastin time was found to be due to acquired hemophilia. Glucocorticoids suppressed both the hypereosinophilia and coagulation abnormality. However, tapering of glucocorticoids led to a relapse of the coagulation abnormality alone, without eosinophilia. Tumor necrosis factor α, interleukin-5, and/or eotaxin-3 may have caused the hypereosinophilia, and interleukin-10 was correlated with the coagulation abnormality. Conclusions To the best of our knowledge, this is the first case in which lymphocytic hypereosinophilic syndrome and IgG4-related disease have overlapped. In addition, our patient is only the second case of hypereosinophilic disease that manifested with acquired hemophilia. Our patient relapsed with the

    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.

    A survey conducted in September 1987 among medical doctors and dental surgeons in Singapore found that most respondents expressed personal reservations and inadequacies in dealing with AIDS/HIV-positive patients and homosexuals. They were also concerned about exposure of their staff to AIDS patients and their likely reactions towards treating these patients. The risk of contagion with AIDS was a major deterrent expressed. The majority of the health professionals had no experience in the management of AIDS related conditions. Although many indicated interest in training, only less than half were willing to undergo what they perceived as the more effective clinically based training themselves.

    The aim of this study is to describe the impact of an education intervention programme on nurses' willingness to care for HIV-positive people in Lithuania. The study utilizes a randomized controlled trial design (RCT). The total sample comprises 185 nurses working in medical, surgical and gynaecological units, and primary health care centres from the same hospital areas in three Lithuanian hospitals. The data were analyzed using SPSS 12.0 and descriptive statistics. Our educational intervention did not have an impact on the nurses' willingness to take care of people living with HIV (PLHIV), as their level of willingness was high already before the education intervention. Further research on this issue is needed to try to understand the forces acting on our nursing staff in order to ensure appropriate care for PLHIV. Copyright © 2010 Elsevier Ltd.

    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.

    Natural killer (NK) cells are innate immune cytotoxic effector cells well known for their role in antiviral immunity and tumor immunosurveillance. In parts, this knowledge stems from rare inherited immunodeficiency disorders in humans that abrogate NK cell function leading to immune impairments, most notably associated with a high susceptibility to viral infections. Phenotypically, these disorders range from deficiencies selectively affecting NK cells to complex general immune defects that affect NK cells but also other immune cell subsets. Moreover, deficiencies may be associated with reduced NK cell numbers or rather impair specific NK cell effector functions. In recent years, genetic defects underlying the various NK cell deficiencies have been uncovered and have triggered investigative efforts to decipher the molecular mechanisms underlying these disorders. Here we review the associations between inherited human diseases and NK cell development as well as function, with a particular focus on defects in NK cell exocytosis and cytotoxicity. Furthermore we outline how reports of diverse genetic defects have shaped our understanding of NK cell biology. Copyright © 2015. Published by Elsevier Inc.

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

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

    Fibroblast cultures from six unrelated patients having a familial type of immunodeficiency combined with microcephaly, developmental delay, and chromosomal instability were studied with respect to their response to ionizing radiation. The cells from five of them resembled those from individuals with ataxia telangiectasia (AT) in that they were two to three times more radiosensitive on the basis of clonogenic cell survival. In addition, after exposure to either X-rays or bleomycin, they showed an inhibition of DNA replication that was less pronounced than that in normal cells and characteristic of AT fibroblasts. However, the patients are clinically very different from AT patients, not showing any signs of neurocutaneous symptoms. Genetic complementation studies in fused cells, with the radioresistant DNA synthesis used as a marker, showed that the patients' cells could complement representatives of all presently known AT complementation groups. Furthermore, they were shown to constitute a genetically heterogeneous group as well. It is concluded that these patients are similar to AT patients with respect to cytological parameters. The clinical differences between these patients and AT patients are a reflection of genetic heterogeneity. The data indicate that the patients suffer from a chromosome-instability syndrome that is distinct from AT.

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

    Objective Incidence of CNS acquired demyelinating syndrome (ADS), especially multiple sclerosis (MS) in children, appears to be on the rise worldwide. The objective of this study was to determine prevalence, clinical presentation, neuroimaging features, and prognosis of different types of ADS in Iranian children. Materials & Methods During the period 2002-2012, all the patients (aged 1-18 years) with ADS, such as MS, acute disseminated encephalomyelitis (ADEM), optic neurotic (ON), Devic disease, and transverse myelitis (TM), referred to the pediatric neurology ward, Nemazee Hospital, Shiraz University of Medical Sciences, were included in this study. Demographic data, clinical signs and symptoms, past and family history, preclinical findings, clinical course, and outcome were obtained. Results We identified 88 patients with ADS in our center. The most prevalent disease was MS with 36.5% (n=32), followed by AEDM 26.1% (n=31), ON 17% (n=13), TM 15.9% (n=14), and Devic disease 4.5% (n=4). MS, ON, TM were more common among females while ADEM was more common in males. Children with ADEM were significantly younger than those with other types of ADS. Family history was positive in 10% of patients with MS. Previous history of recent infection was considerably seen in cases with ADEM. Clinical presentation and prognosis in this study was in accordance with those in previous studies on children. Conclusion In this study, the most common type of ADS was MS, which was more common in female and older age cases. ADEM was more common in male and younger children. ADEM and ON had the best and Devic disease had the worst prognosis. PMID:24949046

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

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

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

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

    Françoise Bachelerie

    2010-01-01

    Full Text Available The WHIM syndrome features susceptibility to human Papillomavirus infection-induced warts and carcinomas, hypogammaglobulinemia, recurrent bacterial infections, B and T-cell lymphopenia, and neutropenia associated with retention of senescent neutrophils in the bone marrow (i.e. myelokathexis. This rare disorder is mostly linked to inherited heterozygous autosomal dominant mutations in the gene encoding CXCR4, a G protein coupled receptor with a unique ligand, the chemokine CXCL12/SDF-1. Some individuals who have full clinical forms of the syndrome carry a wild type CXCR4 gene. In spite of this genetic heterogeneity, leukocytes from WHIM patients share in common dysfunctions of the CXCR4-mediated signaling pathway upon exposure to CXCL12. Dysfunctions are characterized by impaired desensitization and receptor internalization, which are associated with enhanced responses to the chemokine. Our increasing understanding of the mechanisms that account for the aberrant CXCL12/CXCR4-mediated responses is beginning to provide insight into the pathogenesis of the disorder. As a result we can expect to identify markers of the WHIM syndrome, as well as other disorders with WHIM-like features that are associated with dysfunctions of the CXCL12/CXCR4 axis.

    2009-01-01

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

    Full Text Available We present a case of pancytopenia and cutaneous cryptococcosis in a young girl with no complaints of fever, headache and vomiting. Fine-needle aspiration cytology and further investigation for pancytopenia revealed presence of Cryptococcus in skin and bone marrow aspirates. Fungal cultures of the skin aspirates, blood and bone marrow confirmed cryptococcal infection. Counselling and human immunodeficiency virus (HIV test revealed the status of the patient to be retropositive. Although meningitis is the commonest manifestation of cryptococcosis among HIV-infected patients, rare cutaneous manifestation with pancytopenia but with no meningeal signs indicate the HIV status in an endemic area of penicilliosis, Manipur.

  20. Immunomodulation and immunodeficiency.

    Science.gov (United States)

    Foster, Aiden P

    2004-04-01

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

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

    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.

    2011-08-01

    Full Text Available We report the case of a 65-year-old Caucasian woman who experienced two separate episodes of acute renal failure within an 18-month period, both requiring emergency admission and complicated treatment. Each episode was precipitated by hypovolaemia from intestinal fluid losses, but from two rare and independent pathologies. Her first admission was attributed to community-acquired Clostridium difficile-associated diarrhoea (CDAD and was treated in the intensive therapy unit. She returned 18 months later with volume depletion and electrolyte disturbances, but on this occasion a giant hypersecretory villous adenoma of the rectum (McKittrick-Wheelock syndrome was diagnosed following initial abnormal findings on digital rectal examination by a junior physician. Unlike hospital-acquired C. difficile, community-acquired infection is not common, although increasing numbers are being reported. Whilst community-acquired CDAD can be severe, it rarely causes acute renal failure. This case report highlights the pathological mechanisms whereby C. difficile toxin and hypersecretory villous adenoma of the rectum can predispose to acute renal failure, as well as the values of thorough clinical examination in the emergency room, and early communication with intensivist colleagues in dire situations.

    The acquired immune deficiency syndrome (AIDS) results from a lymphotropic retrovirus (HTLV-III) infection and is characterized by specific opportunistic infections and malignancies. The virus is transmitted primarily by semen and blood. Infection is limited principally to defined risk groups, i.e., homosexual men and intravenous drug users. Head and neck manifestations include cervical lymphadenopathy and Kaposi's sarcoma. Oral manifestations include Kaposi's sarcoma, candidiasis, hairy leukoplakia, precocious periodontal disease, xerostomia, herpes simplex, recurrent aphthae, erythema multiforme, and venereal warts. Although HTLV-III is present in saliva, there are no reported cases of transmission secondary to dental procedures. Appropriate precautions and techniques are recommended in treating patients at risk for AIDS.

    The spine is the most common site of skeletal involvement in tuberculosis. The radiologic features are reportedly characterized by destruction of the vertebral body, subligamentous extension or subchondral penetration, frequent paravertebral abscess formation and late involvement of the disk space. We experienced a case of a 25-year-old male who was a human immunodeficiency virus carrier without antiretroviral therapy. Incidental findings on abdominal computed tomography included multiple well-demarcated and ovoid osteolytic lesions with hyperdense rims disseminated in the thoracic, lumbar, and sacrum vertebrae, as well as in both ilii. On the lumbar spine magnetic resonance imaging, multiple small round lesions of isointense signal intensity with peripheral hyperintense rims were found on both T1- and T2-weighted imaging. The lesions had peripheral rim enhancement on gadolinium-enhanced T1-weighted imaging. Based on our experience, this rare image finding is one of the manifestations of disseminated tuberculosis.

    Full Text Available Monogenic primary immunodeficiency syndromes can affect one or more endocrine organs by autoimmunity during childhood. Clinical manifestations include type1 diabetes mellitus, hypothyroidism, adrenal insufficiency and vitiligo. LPS-responsive beige-like anchor protein (LRBA deficiency was described in 2012 as a novel primary immunodeficiency, predominantly causing immune dysregulation and early onset enteropathy. We describe the heterogeneous clinical course of LRBA deficiency in two siblings, mimicking an autoimmune polyendocrine disorder in one of them in presence of the same underlying genetic mutation. The third child of consanguineous Egyptian parents (Patient 1 presented at six months of age with intractable enteropathy and failure to thrive. Later on he developed symptoms of adrenal insufficiency, autoimmune haemolytic anaemia, thrombocytopenia, and infectious complications due to immunosuppressive treatment. The severe enteropathy was non-responsive to the standard treatment and led to death at the age of 22 years. His younger sister (Patient 2 presented at the age of 12 to the endocrinology department with decompensated hypothyroidism, perioral vitiligo, delayed pubertal development, and growth failure without enteropathy and immunodeficiency.Using whole-exome sequencing (WES we identified a homozygous frameshift mutation (c.6862delT, p.Y2288MfsX29 in the LRBA gene in both siblings. To our knowledge our patient (patient 2 is the first case of LRBA deficiency described with predominant endocrine phenotype without immunodeficiency and enteropathy. LRBA deficiency should be considered as underlying disease in pediatric patients presenting with autoimmune endocrine symptoms. The same genetic mutation can manifest with a broad phenotypic spectrum without genotype-phenotype correlation. The awareness for disease symptoms among non-immunologists might be a key to early diagnosis. Further functional studies in LRBA deficiency are necessary to

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

    2017-07-01

    Full Text Available We present a 35-year-old male patient with Bureau-Barrière syndrome. Bureau-Barrière syndrome is an ulcero-mutilating acropathy almost invariably associated with excessive alcohol intake. It presents with a triad of trophic skin changes with recurrent ulcerations, bone lesions and nerve damage. The clinical presentation includes chronic painless plantar ulcerations with periulcerous hyperkeratosis, hyperhidrosis, livedoid skin colour, nail dystrophy, widening and infiltration of the toes and common interdigital mycoses. Other non-specific skin changes related to the alcohol consumption are commonly observed as well. The condition affects mainly middle-aged men suffering from alcoholism. Often a bilateral location at the lower limb of male alcoholics has been described, as in our patient. Successful treatment of the Bureau-Barrière syndrome requires an interdisciplinary approach. Cessation of alcohol intake and smoking is of paramount importance.

    Full Text Available Dyskeratosis congenita (DC is a heterogeneous inherited bone marrow failure and cancer predisposition syndrome in which germline mutations in telomere biology genes account for approximately one-half of known families. Hoyeraal Hreidarsson syndrome (HH is a clinically severe variant of DC in which patients also have cerebellar hypoplasia and may present with severe immunodeficiency and enteropathy. We discovered a germline autosomal recessive mutation in RTEL1, a helicase with critical telomeric functions, in two unrelated families of Ashkenazi Jewish (AJ ancestry. The affected individuals in these families are homozygous for the same mutation, R1264H, which affects three isoforms of RTEL1. Each parent was a heterozygous carrier of one mutant allele. Patient-derived cell lines revealed evidence of telomere dysfunction, including significantly decreased telomere length, telomere length heterogeneity, and the presence of extra-chromosomal circular telomeric DNA. In addition, RTEL1 mutant cells exhibited enhanced sensitivity to the interstrand cross-linking agent mitomycin C. The molecular data and the patterns of inheritance are consistent with a hypomorphic mutation in RTEL1 as the underlying basis of the clinical and cellular phenotypes. This study further implicates RTEL1 in the etiology of DC/HH and immunodeficiency, and identifies the first known homozygous autosomal recessive disease-associated mutation in RTEL1.

    Gerstmann's syndrome (GS) is defined by a clinical tetrad including acalculia, finger anomia, left-right disorientation and agraphia. In this article, we describe the case of a 42-year-old woman suffering from an aggressive relapsing-remitting multiple sclerosis in which a systematic neuropsychological assessment revealed Gertsmann's syndrome amongst other cognitive disturbances. Brain MRI showed a high concentration of plaques within a left subcortical parietal region that has recently been considered as a crucial node for GS appearance. However, history, taking provided information suggesting that an important part of the GS, may have been present since childhood, evoking a possible neurodevelopmental origin in this patient. This article reviews the role of the GS concept in contemporary literature, with a special attention to pathophysiological hypotheses and to precautions necessary to study such cases.

This disorder is characterized by a clinical appearance of severe growth hormone deficiency with high levels of circulating growth hormone in contrast to low serum insulin-like growth factor 1 values. Case presentation We report the case of a 15-year-old Caucasian girl who was diagnosed with Silver-Russell syndrome at the age of four and a half years. Recombinant growth hormone was administered for 18 months without an appropriate increase in growth velocity. At the age of seven years, her serum growth hormone levels were high, and an insulin-like growth factor 1 generation test did not increase insulin-like growth factor 1 levels (baseline insulin-like growth factor 1 levels, 52 μg/L; reference range, 75 μg/L to 365 μg/L; and peak, 76 μg/L and 50 μg/L after 12 and 84 hours, respectively, from baseline. The genetic analysis showed that the patient was homozygous for the R217X mutation in the growth hormone receptor gene, which is characteristic of Laron syndrome. On the basis of these results, the diagnosis of primary growth hormone insensitivity syndrome was made, and recombinant insulin-like growth factor 1 therapy was initiated. The patient's treatment was well tolerated, but unexplained central hypothyroidism occurred at the age of 12.9 years. At the age of 15 years, when the patient's sexual development was almost completed and her menstrual cycle occurred irregularly, her height was 129.8 cm, which is 4.71 standard deviations below the median for normal girls her age. Conclusion The most important functional tests for the diagnosis of growth hormone insensitivity are the insulin-like growth factor 1 generation test and genetic analysis. Currently, the only effective

    2015-01-01

    Full Text Available 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.

    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.

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

    Pulmonary complications in children infected by human immunodeficiency virus (HIV) are common and may be the first manifestation of acquired immunodeficiency syndrome (AIDS). The aim of our study was to review pulmonary diseases and complications in pediatric patients with HIV infection in a large tertiary hospital in Santiago, Chile. We performed a retrospective, descriptive analysis of 17 patients with HIV infection controlled at the Hospital Dr. Sótero del Rio. Respiratory complications/diseases were: overall pneumonia (n: 14), recurrent pneumonia (n: 10), citomegalovirus associated pneumonia (n: 4), Pneumocystis jiroveci associated pneumonia (n: 1) pulmonary tuberculosis (n: 1), lymphoid interstitial pneumonia (n: 3) and chronic pulmonary disease (n: 7). Microorganisms isolated were mostly atypical and frequently associated with severe and chronic pulmonary damage. A high degree of suspicion is required to detect atypical microorganisms promptly, in order to rapidly implement pathogen targeted therapy that could potentially decrease the possibility of sequelae.

    1996-12-01

    A national survey of investigators caring for human immunodeficiency virus (HIV)-infected women was undertaken to describe the clinical presentation of idiopathic genital ulcer disease. Patients with negative syphilis and herpes simplex testing and/or negative genital ulcer biopsy were included in this study. Study participants (n = 29) were generally severely immunocompromised (median CD4 cell count was 50/mm3, and 68% had an acquired immunodeficiency syndrome [AIDS]-defining opportunistic process). Thirty-seven percent had coexistent oral ulcers and 19% had their genital ulcer progress to fistula formation (four rectovaginal and one vaginal-perineal). There was generally a favorable response to topical, systemic, and intralesional steroid treatment. This study suggests that idiopathic or probable aphthous genital ulcers in women have similar clinical characteristics to aphthous oroesophageal ulcers. Although infrequent, these genital ulcers can cause severe morbidity. Further research is warranted to better define the pathophysiology and optimal management.

    Over the last 2 decades human immunodeficiency virus (HIV) infection has become a chronic disease requiring long-term management. Aging, antiretroviral therapy, chronic inflammation, and several other factors contribute to the increased risk of cardiovascular disease in patients infected with HIV. In low-income and middle-income countries where antiretroviral therapy access is limited, cardiac disease is most commonly related to opportunistic infections and end-stage manifestations of HIV/acquired immunodeficiency syndrome, including HIV-associated cardiomyopathy, pericarditis, and pulmonary arterial hypertension. Cardiovascular screening, prevention, and risk factor management are important factors in the management of patients infected with HIV worldwide. Copyright © 2016 Elsevier Inc. All rights reserved.

    To determine the effectiveness of a recorded information line in communicating health risk during the emergence of a new disease, hantavirus pulmonary syndrome (HPS), in the Edmonton area and to study the accuracy of recall of information about hantavirus among the general public. A random telephone survey of residents five months after a death from HPS had occurred. The number of residents who received their information from the recorded line was quite low (approximately 2%), and more people remembered receiving their information through the news media, particularly television (74%) and newspaper (57%). An information line by itself will not communicate risk effectively during an outbreak or other emergent health situation. However, an information line used in conjunction with news media proved effective in providing ongoing, accurate information and allaying public fears in a low-risk situation.

    Veno-occlusive disease with immunodeficiency (VODI) is an autosomal recessive disorder of combined immunodeficiency (CID) and hepatic injury. Hematopoietic stem cell transplantation (HSCT) - the only definitive treatment for CID - appeared to have a high rate of complications in a previous report. In this study, we describe a new group of patients with VODI highlighting further clinical and immunologic aspects of this disease and re-evaluating the effectiveness of HSCT for the treatment of this disorder. Review of clinical data, immunologic features, molecular studies, treatment, and final outcome of eight kindred members with VODI. The patients described had clinical and immunologic findings consistent with VODI. The molecular studies revealed a new mutation in the SP110 gene. HSCT was carried out in five patients and was successful in three. The diagnosis of VODI should be considered in all patients regardless of ethnicity with a severe combined immunodeficiency (SCID)-like presentation, especially with a normal mitogen response, or with signs of hepatic injury. VODI is a primary immune deficiency, which can be successfully corrected by bone marrow transplantation if applied early in the course of disease using appropriate conditioning. © 2013 John Wiley & Sons A/S.

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

    The silent sinus syndrome (SSS) is a rare clinical entity characterized by painless spontaneous enophthalmos, hypoglobus, and facial deformities secondary to chronic maxillary sinus atelectasis. The aim of this study was to present an SSS diagnostic feature and evaluate the relationship between nasal septum deviation and maxillary sinus volume. A retrospective chart review of the clinical characteristics of 20 patients diagnosed with SSS between January 2013 and July 2014 were analyzed by the Department of Otorhinolaryngology of University Hospital Complex of Santiago de Compostela. 14 patients were females and six males. The mean age was 43 years (range 28-67 years). The right maxillary sinus was involved in 12 patients and the left maxillary sinus in eight patients. There was no statistical difference between gender and the presence of SSS. Maxillary sinus sizes were significantly smaller on the same side as the deviation (p craneo-caudal photographs. The present study demonstrates that, in adult patients, SSS generally presents a septal deviation to the affected maxillary sinus. We recommend performing a paranasal sinus CT scan when the patient has a deviated nasal septum, retraction of the malar eminence (evidenced from the viewpoint cranio-caudal facial) and hypoglobus. FESS performing postero-anterior uncinectomy and enlargement of the maxillary ostium is recommended to restore sinus pressure and prevent progression of the enophthalmos, hypoglobus and facial deformities.

    One of the great advances in clinical medicine was the recognition of the pleomorphism of the immune response and the multiple afferent and efferent limbs of antigen processing and responsiveness. A significant contribution to this understanding was derived from studies of human immunodeficiency states, including both inherited and acquired syndromes. Amongst these syndromes, one of the most common, and least understood, is common variable immune deficiency (CVID). CVID is a syndrome that leads to a reduction in serum immunoglobulins and complications including recurrent infections. Management includes immunoglobulin replacement therapy; however, patients with CVID are at risk for complications of exogenous immunoglobulin administration as well as CVID-associated diseases such as autoimmune processes and malignancies. To assess the current state of knowledge in the field, we performed a literature review of a total of 753 publications covering the period of 1968 until 2008. From this list, 189 publications were selected for discussion. In this review, we demonstrate that while the molecular basis of CVID in many cases remains incompletely understood, significant strides have been made and it is now clear that there is involvement of several pathways of immune activation, with contributions from both T and B cells. Furthermore, despite the current gaps in our knowledge of the molecular pathogenesis of the syndrome, there have been dramatic advances in management that have led to improved survival and significantly reduced morbidity in affected patients.

    Full Text Available Abstract Introduction Lemierre's syndrome is septic thrombophlebitis of the internal jugular vein leading to metastatic septic complications following an oropharyngeal infection. It is usually caused by the anaerobe, Fusobacterium necrophorum. Of late, meticillin-resistant Staphylococcus aureus is increasingly being recognised as a cause of community-acquired skin and soft tissue infections. We report a rare case of Lemierre's syndrome caused by community-acquired meticillin-resistant Staphylococcus aureus infection. Case presentation A previously healthy 16-year-old girl presented with fever of 13 days duration, painful swelling around the right eye and diplopia followed by the appearance of pulmonary infiltrates. Imaging studies confirmed the clinical suspicion of bilateral jugular venous thrombosis with septic pulmonary embolism. Meticillin-resistant Staphylococcus aureus was isolated on blood cultures. The hospital course was complicated by massive haemoptysis and pulmonary aspiration necessitating mechanical ventilation. The patient subsequently made a complete recovery. Conclusion Lemierre's syndrome, although rare, is a potentially lethal but treatable complication of head and neck sepsis. Early clinical recognition of Lemierre's syndrome and appropriate antibiotic treatment can be life-saving. One should consider the possibility of community-acquired meticillin-resistant Staphylococcus aureus infection in patients with suspected Lemierre's syndrome.

    Ritonavir and atazanavir (ATZ) are protease inhibitors (PI) that inhibit the P450 3A4 cytochrome. They are used together to boost ATZ levels and reduce pill burden in human immunodeficiency virus infection, but association with medications metabolized by this cytochrome can cause serious adverse effects. Several cases of Cushing's syndrome have been reported when patients received inhaled therapy with fluticasone for asthma, sometimes complicated by secondary adrenal failure after stopping fluticasone. We report a case of Cushing's syndrome associated with onset of diabetes mellitus in a patient treated with boosted PI (ATZ and ritonavir) for HIV 2 (CD4360/ml). Asthma was treated with inhaled fluticasone 1500mug/day for several months that was stopped at admission. A few days later, typical secondary adrenal failure developed and was confirmed by dosage of cortisol and ACTH, both low. Hydrocortisone replacement treatment resulted in rapid improvement of symptoms. Diabetes was initially treated with insulin then sulfonyluraes, but repeated hypoglycemias lead to diet alone. Physicians should be aware of the potential danger of the association of "boosted" IP and some kind of inhaled corticotherapy.

    Full Text Available 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.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.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.Transforming growth factor-β1 T869C polymorphism, correlated with high serum transforming growth factor-β1 levels, is associated with susceptibility to acquired sick sinus syndrome.

Older age was associated with lower perceived overall QOL. Females were more likely to have lower QOL scores in the social and psychological domains. Higher CD4 counts and a married status were significant predictors of higher QOL scores in the environmental domain. Conclusion: Being older, female, single, and having advanced clinical stage is associated with lower QOL scores in people living with AIDS. Lowest QOL scores were seen in the psychological domain suggesting the need of psychological interventions. Keywords: quality of life, AIDS, Nepal, WHO QOL-BREF

  16. Genetic Associations in Acquired Immune-Mediated Bone Marrow Failure Syndromes: Insights in Aplastic Anemia and Chronic Idiopathic Neutropenia

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Increasing interest on the field of autoimmune diseases has unveiled a plethora of genetic factors that predispose to these diseases. However, in immune-mediated bone marrow failure syndromes, such as acquired aplastic anemia and chronic idiopathic neutropenia, in which the pathophysiology results from a myelosuppressive bone marrow microenvironment mainly due to the presence of activated T lymphocytes, leading to the accelerated apoptotic death of the hematopoietic stem and progenitor cells, such genetic associations have been very limited. Various alleles and haplotypes of human leucocyte antigen (HLA molecules have been implicated in the predisposition of developing the above diseases, as well as polymorphisms of inhibitory cytokines such as interferon-γ, tumor necrosis factor-α, and transforming growth factor-β1 along with polymorphisms on molecules of the immune system including the T-bet transcription factor and signal transducers and activators of transcription. In some cases, specific polymorphisms have been implicated in the outcome of treatment on those patients.

    To compare acquired immune deficiency syndrome (AIDS) related knowledge, attitudes, behaviors and their influencing factors among college students in different years in Beijing, and to provide evidence for targeted health education among college students in future. College students were selected by the stratified cluster sampling method, and a questionnaire survey was conducted among college students in year 2006 and 2016 in Beijing. The sample sizes were 1 800 and 3 001 college students, respectively. The contents of the questionnaire included: socio-demographic characteristics, AIDS related knowledge, AIDS related attitude, sex intercourse and its related risk behaviors, condom use intension, and AIDS related health education. Compared with the year 2006, the average AIDS knowledge scores of college students in year 2016 dropped from 12.78±1.95 to 11.90±2.56 (t=12.91, Pinfluencing factors of intention on condom use were male (OR=0.713), self-efficacy of condom purchase (OR=0.876), never received sex education before college (OR=0.752), self-efficacy of condom use (OR=1.135), belief of condom use (OR=1.775), and attitude towards AIDS patients (OR=1.136). AIDS related knowledge, attitudes and behaviors among college students have been changed, AIDS related health education should be designed and improved based on new characteristics of college students. AIDS health education in colleges should pay more attention to sex attitude and sex responsibility and self-protection awareness among college students as well.

    Immunodeficiency, centromeric instability, and facial anomalies (ICF) syndrome is an extremely rare autosomal recessive disease. The immune phenotype is characterized by hypogammaglobulinemia in the presence of B cells. T cell lymphopenia also develops in some patients. We sought to further investigate the immune defect in an ICF patient with a novel missense mutation in DNMT3B and a severe phenotype. Patient lymphocytes were examined for subset counts, immunoglobulin levels, T and B cell de novo production (via excision circles) and receptor repertoire diversity. Mutated DNMT3B protein structure was modeled to assess the effect of a mutation located outside of the catalytic region on protein function. A novel homozygous missense mutation, Ala585Thr, was found in DNMT3B. The patient had decreased B cell counts with hypogammaglobulinemia, and normal T cell counts. CD4(+) T cells decreased over time, leading to an inversion of the CD4(+) to CD8(+) ratio. Excision circle copy numbers were normal, signifying normal de novo lymphocyte production, but the ratio between naïve and total B cells was low, indicating decreased in vivo B cell replication. T and B cell receptor repertoires displayed normal diversity. Computerized modeling of the mutated Ala585 residue suggested reduced thermostability, possibly affecting the enzyme kinetics. Our results highlight the existence of a T cell defect that develops over time in ICF patient, in addition to the known B cell dysfunction. With intravenous immunoglobulin (IVIG) treatment ameliorating the B cell defect, the extent of CD4(+) lymphopenia may determine the severity of ICF immunodeficiency.

    2011-11-01

    Full Text Available Abstract Primary immunodeficiency disorder (PID refers to a heterogeneous group of over 130 disorders that result from defects in immune system development and/or function. PIDs are broadly classified as disorders of adaptive immunity (i.e., T-cell, B-cell or combined immunodeficiencies or of innate immunity (e.g., phagocyte and complement disorders. Although the clinical manifestations of PIDs are highly variable, most disorders involve at least an increased susceptibility to infection. Early diagnosis and treatment are imperative for preventing significant disease-associated morbidity and, therefore, consultation with a clinical immunologist is essential. PIDs should be suspected in patients with: recurrent sinus or ear infections or pneumonias within a 1 year period; failure to thrive; poor response to prolonged use of antibiotics; persistent thrush or skin abscesses; or a family history of PID. Patients with multiple autoimmune diseases should also be evaluated. Diagnostic testing often involves lymphocyte proliferation assays, flow cytometry, measurement of serum immunoglobulin (Ig levels, assessment of serum specific antibody titers in response to vaccine antigens, neutrophil function assays, stimulation assays for cytokine responses, and complement studies. The treatment of PIDs is complex and generally requires both supportive and definitive strategies. Ig replacement therapy is the mainstay of therapy for B-cell disorders, and is also an important supportive treatment for many patients with combined immunodeficiency disorders. The heterogeneous group of disorders involving the T-cell arm of the adaptive system, such as severe combined immunodeficiency (SCID, require immune reconstitution as soon as possible. The treatment of innate immunodeficiency disorders varies depending on the type of defect, but may involve antifungal and antibiotic prophylaxis, cytokine replacement, vaccinations and bone marrow transplantation.

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

    Objective To study the clinical characteristic of acquired immune deficiency syndrome (AIDS) patients younger than 15 years old and to explore the influence of human immunodeficiency virus (HIV) infection on them. Methods The clinical information, including demographic profile, clinical stages of the disease, laboratory test results and developmental status were gathered from 275 antiretroviral therapy naive patients. Results Seventy eight point nine percent patients were infected by vertical transmission. Sixteen percent were infected by receiving blood products. The average age was (7.6±3. 7) years, with 5 cases younger than 1 year old, 104 cases ranging from 1 - 5 years and 166 cases elder than 6 years. Seventy point one percent patients were classified as stage 3 or 4 according to World Health Organization definitions. The average CD4 count was ( 137 ± 159 )/μL, ( 304 ± 317 ) /μL and ( 1 246 ± 776 )/μL respectively in children elder than 6 years, ranging from 1 to 5 years and younger than 1 year. One hundred and eighty one cases suffered from anemia on different severity grading. The most common HIV related symdromes included persistent fever, skin damage, persistent diarrhea, oral candidiasis and recurrent upper respiratory tract infection. Among these infected children, 49. 6% showed height lower than x - 2s and 19. 9% showed weight lower than x - 2s. Conclusions Most survival pediatric AIDS patients are elder than 6 years.

    LP-BM5 murine leukemia virus, a derivative of Duplan-Laterjet virus, contains a mixture of replication-competent B-tropic ecotropic and mink cell focus-inducing (MCF) viruses and a defective genome that is the proximal cause of a syndrome, murine AIDS (MAIDS), characterized by lymphoproliferation and immunodeficiency. The defective (BM5d) and ecotropic components of this mixture were molecularly cloned, and complete (BM5d) or partial (ecotropic) nucleotide sequences were determined. BM5d closely resembled the Du5H genome cloned from the Duplan virus, featuring a highly divergent p12 sequence in the gag open reading frame. In MAIDS-sensitive C57BL/6 mice, BM5d was detected in tissues within 2 weeks of infection but was absent from tissues of the MAIDS-resistant strain, A/J, 12 weeks after infection. B-cell-lineage tumors from mice with MAIDS contained and expressed BM5d, and clonal integrations of this genome were variably associated with clonal expansions of B cells in infected mice. Finally, mRNA crosshybridizing with a probe for BM5d was present in spleen but not kidney cells of uninfected B6 mice.

    Abstract Cyclical thrombocytosis, acquired von Willebrand syndrome, aggressive non-melanoma skin cancers and other hydroxyurea complications have been reported in Philadelphia-negative myeloproliferative neoplasms (MPNs), but their incidence and clinical consequences have not been defined in a large cohort of patients. We conducted a retrospective analysis of 188 consecutive patients with MPNs specifically addressing the incidence of these complications. Cyclical thrombocytosis was documented in 29 patients (15%), the majority of whom were receiving hydroxyurea. Acquired von Willebrand syndrome was identified in 17 of the 84 screened patients (20%), but was not associated with any major bleeding complications. Non-melanoma skin cancers were reported in 51 patients (27%). Hydroxyurea-related fever occurred in nine of 149 patients (6%) who received hydroxyurea. Seventy-three patients (39%) experienced a total of 98 major thrombotic events, with the majority of these occurring prior to or within 3 months of the diagnosis. Cyclical thrombocytosis, acquired von Willebrand syndrome, aggressive non-melanoma skin cancers and other hydroxyurea-related complications are not infrequent in MPNs and have important clinical consequences for management.

    Nicholas L Rider

    2015-01-01

    Full Text Available Unbiased genetic diagnosis has increasingly associated seemingly unrelated somatic and immunological phenotypes. We report a male infant who presented within the first year of life with physical growth impairment, feeding difficulties, hyperemesis without diarrhea, and abnormal hair findings suggestive of trichorrhexis nodosa. With advancing age, moderate global developmental delay, susceptibility to frequent viral illnesses, otitis media and purulent conjunctivitis were identified. Because of the repeated infections an immunological evaluation was pursued and identified impaired antibody memory responses following pneumococcal vaccine administration. Immunoglobulin replacement therapy and nutritional support were employed as mainstays of therapy. The child is now aged 12 years and still without diarrhea. Whole exome sequencing identified compound heterozygous mutations in the TTC37 gene, a known cause of the Trichohepatoenteric Syndrome (THES. This case extends the known phenotype of THES and defines a potential subset for inclusion as an immune overlap syndrome.

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

    2012-04-01

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

    2008-08-01

    Full Text Available Abstract Introduction Acquired partial lipodystrophy or Barraquer-Simons syndrome is a rare form of progressive lipodystrophy. The etiopathogenesis of adipose tissue atrophy in these patients is unknown. Case presentation This is a case report of a 44-year-old woman with acquired partial lipodystrophy. To obtain insight into the molecular basis of lipoatrophy in acquired partial lipodystrophy, we examined gene expression in adipose tissue from this patient newly diagnosed with acquired partial lipodystrophy. A biopsy of subcutaneous adipose tissue was obtained from the patient, and DNA and RNA were extracted in order to evaluate mitochondrial DNA abundance and mRNA expression levels. Conclusion The expression of marker genes of adipogenesis and adipocyte metabolism, including the master regulator PPARγ, was down-regulated in subcutaneous adipose tissue from this patient. Adiponectin mRNA expression was also reduced but leptin mRNA levels were unaltered. Markers of local inflammatory status were unaltered. Expression of genes related to mitochondrial function was reduced despite unaltered levels of mitochondrial DNA. It is concluded that adipogenic and mitochondrial gene expression is impaired in adipose tissue in this patient with acquired partial lipodystrophy.

    2006-01-01

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

Methods Two hundred and seventy-seven mothers who acquired HIV prenatally or before pregnancy and their 322children from Yi-ning city of Xinjiang Uygur autonomous region and some counties of central China were enrolled in this study from January 2000 to December 2009.Subtypes of HIV were determined by detection of Gag sequence,the rate of HIV transmission from mother to child was calculated and its related factors were analyzed by Chi-square test and Logistic regression analysis. Results The HIV subtype of all mothers who were infected through blood (n=174) was B'.The major subtype of mothers who were infected via sexuality (n =58) was recombined subtype CRF01-BC (n=35) and CRF-AE (n=20),accounting for 60.3% and 34.5%,respectively,and only 3 mothers with B'subtype (5.2%).Twelve infants died before HIV detection,and 108 infants out of the rest 310infants were found to be HIV positive, giving the HIV mother-to-child transmission rate of 34.8% (95% CI:29.5%-40.1%).The infection rate of bottle feeding infants was lower than that of breastfeeding infants [12.5% (6/48) vs 38.9% (102/262),x2 =12.484,P=0.000].The infection rate of the infants whose mothers' HIV infection <7 years was lower than that of the infants whose mothers' HIV infection ≥7 years [28.8% (46/160) vs 54.2% (32/59),x2 =12.211,P=0.000].Multi-factor Logistic analysis showed that the duration of maternal HIV infection (OR =1.342,95% CI:1.189-1.515,P=0.000) and duration of breastfeeding (OR =1.137,95% CI:1.053-1.227,P=0.001) were risk factors of HIV vertical transmission. Conclusions The HIV subtypes might be associated with transmission route.Formula feeding could decrease the vertical transmission rate of HIV,while long duration of maternal HIV infection and breastfeeding might increase the vertical transmission rate

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

    The authors, after reviewing the current literature about the serological pattern of anti-HIV antibodies detected with Western Blot and the research of the viral antigen in AIDS, report the study of the above mentioned parameters in two HIV seropositive drug addicts. Case 1 (symptomless seropositive) presented a reactivity against p24 and p55 a month after an acute HIV infection and a more delayed reactivity to the whole anti-HIV antibody pattern. Case 2 (which developed full-blown AIDS), together with clinical and immunological deterioration, had a decline and disappearance of antibodies to p24 and persistence of reactivity against gp41 and detection of viral antigen. Diagnostic and prognostic significance of these results are discussed.

    临床上常用的一些药物如抗组胺药、抗微生物药、抗精神病药以及胆碱能拮抗剂等均可诱导获得性长QT综合征(acquired Long QT syndrome,aLQTs)的发生甚至尖端扭转型室性心动过速(Torsades de Pointes,TdP).正常情况下发生概率低,但当存在各种易感因素时发生率增高.主要的易感因素包括致先天性长QT综合征(congenital Long QT syndrome,cLQTs)的基因突变、药物代谢酶遗传多态性,以及药物相互作用、年龄、性别、电解质平衡紊乱等非遗传因素.我们需要正确认识aLQTs发生机理和相关易感因素,进一步构建其遗传背景.%Some drugs, such as antiarrhythmic drugs, antihistamines, antimicrobials, antipsychotics and cholinergic antagonists, can cause acquired long QT syndrome (aLQTs) and Torsades de Pointes (TdP). Although it is rare, the incidence rate becomes higher when several predisposing factors exist. The predisposing factors include mutations that are associated with congenital long QT syndrome (cLQTs) , the polymorphisms of drug's metabolic enzymes, and non-genetic factors such as drug interaction, age, gender and electrolyte disturbances. Recognition of the mechanisms and predisposing factors is necessary for preventing the occurrence of the fatal toxic effect of these drugs. We should establish the genetic background of aLQTs.

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

    Human immunodeficiency virus (HIV), the causative agent of acquired immune deficiency syndrome, has claimed innumerable lives in the past. Many biomolecules which suppress HIV replication and also other biomolecules that inhibit enzymes essential to HIV replication have been reported. Proteins including a variety of milk proteins, ribosome-inactivating proteins, ribonucleases, antifungal proteins, and trypsin inhibitors; peptides comprising cathelicidins, defensins, synthetic peptides, and others; polysaccharides and polysaccharopeptides; nucleosides, nucleotides, and ribozymes, demonstrated anti-HIV activity. In many cases, the mechanism of anti-HIV action has been elucidated. Strategies have been devised to augment the anti-HIV potency of these compounds.

    Kaposi sarcoma-associated herpesvirus (KSHV),also known as human herpesvirus 8 (HHV-8),is discovered in 1994 from Kaposi's sarcoma (KS) lesion of an acquired immunodeficiency syndrome (AIDS)patient.In addition to its association with KS,KSHV has also been implicated as the causative agent of two other AIDS-associated malignancies:primary effusion lymphoma (PEL) and multicentric Castleman's disease (MCD).KSHV is a complex DNA virus that not only has the ability to promote cellular growth and survival for tumor development,but also can provoke deregulated angiogenesis,inflammation,and modulate the patient's immune system in favor of tumor growth.As KSHV is a necessary but not sufficient etiological factor for KS,human immunodeficiency virus (HIV) is a very important cofactor.Here we review the basic information about the biology of KSHV,development of pathogenesis and interaction between KSHV and HIV.

    The psychological problems of the families of human immunodeficiency virus 1 (HIV-1)-infected people, and of the health workers taking care of them, have been addressed in a few empirical studies and in several anecdotal reports and theoretical contributions. Apparently, HIV-1 infection and acquired immunodeficiency syndrome (AIDS) are able to elicit a wide range of emotional reactions, from rejection and refusal to provide care to immersion in the infected person's needs and burnout. Since irrational fears and attitudes play an important role in conditioning these reactions, education may not be sufficient to change behaviour. Counselling sessions and mutual support groups are often the most appropriate contexts where fears and concerns can receive an individually tailored response, and where formal and informal caregivers can be helped to manage stress.

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

    In contrast to the established role of Helicobacter pylori gastritis in gastritis and duodenal ulcer in general, conflicting results have been reported in patients with human immunodeficiency virus (HIV) infection and the acquired immunodeficiency syndrome. The seroprevalence during early HIV...... infection is unknown. We retrospectively studied 102 patients with HIV infection early during the infection and in most cases in asymptomatic patients. Serological IgG antibody response to H. pylori was assessed by ELISA. Compared with an age-matched control group the seroprevalence of H. pylori positivity......) and 2 patients had H. pylori seroconverted, indicating an incidence of new infection of 2%/year. In conclusion, previous reports have underestimated the prevalence of H. pylori infection in HIV patients, which seems to be similar to that in an HIV-negative population....

    Full Text Available Human immunodeficiency virus (HIV endocrinopathy encompasses a broad spectrum of disorders. Almost all the endocrine organs are virtually affected by HIV infection. HIV can directly alter glandular function. More commonly secondary endocrine dysfunction occurs due to opportunistic infections and neoplasms in immunocompromised state. The complex interaction between HIV infection and endocrine system may be manifested as subtle biochemical and hormonal perturbation to overt glandular failure. Antiretroviral therapy as well as other essential medications often result in adverse endocrinal consequences. Apart from adrenal insufficiency, hypogonadism, diabetes and bone loss, AIDS wasting syndrome and HIV lipodystrophy need special reference. Endocrinal evaluation should proceed as in other patients with suspected endocrine dysfunction. Available treatment options have been shown to improve quality of life and long-term mortality in AIDS patients.

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

    Full Text Available Chlamydia trachomatis (CT infections are among the sexually transmitted diseases known to increase the risk for human immunodeficiency virus infection. Serum samples from 34 consenting AIDS patients which attended the Government-approved Antiretroviral Treatment (ART Facility at the National Institute for Pharmaceutical Research and Development (NIPRD, Abuja between April 2005 and March 2006 were screened by enzyme immunoassay (EIA for the presence of anti-CT antibodies using ImmunoComb® Chlamydia Bivalent IgG Test kit (Orgenics, Israel. Anti-CT antibodies were detected in ten (29.4% of the thirty-four patients tested. The detection rate was higher among the females (33.3% than the males (23.1%. Patients of the age group 31-45 years had the highest detection of anti-C. trachomatis antibodies, followed by those of age group 16-30 years. The result of the present study suggests the presence of anti-CT antibodies in AIDS patients, and reinforces the need for routine screening for anti-CT antibodies as a necessary intervention to reduce the burden of chlamydial diseases and to reduce the risk of HIV and its spread in Nigeria. The outcome of this study also provides justification for the possible inclusion of anti-chlamydial agents in the National AIDS Management Plan to treat associated C. trachomatis infections.

    1987-12-01

    Almost all homosexual patients with acquired immunodeficiency syndrome are also actively infected with human cytomegalovirus (HCMV). The authors have hypothesized that an interaction between HCMV and human immunodeficiency virus (HIV), the agent that causes acquired immunodeficiency syndrome, may exist at a molecular level and contribute to the manifestations of HIV infection. In this report, they demonstrate that the immediate-early gene region of HCMV, in particular immediate-early region 2, trans-activates the expression of the bacterial gene chloramphenicol acetyltransferase that is fused to the HIV long terminal repeat and carried by plasmid pHIV-CAT. The HCMV immediate-early trans-activator increases the level of mRNA from the plamid pHIV-CAT. The sequences of HIV that are responsive to trans-activation by the HDMV immediate-early region are distinct from HIV sequences that are required for response to the HIV tat. The stimulation of HIV gene expression by HDMV gene functions could enhance the consequences of HIV infection in persons with previous or concurrent HCMV infection.

    The aim of the present study was to determine the Chlamydia trachomatis prevalence and to identify the demographic, behavioural and clinical factors associated with C. trachomatis in human immunodeficiency virus infected men. This was a cross-sectional study of C. trachomatis prevalence among human immunodeficiency virus-infected men enrolled at the Outpatient clinic of acquired immunodeficiency syndrome of the Fundação de Medicina Tropical Dr. Heitor Vieira Dourado in Manaus, Amazonas, Brazil. C. trachomatis deoxyribonucleic acid from urethral samples was purified and submitted to real time polymerase chain reaction to identify the presence of C. trachomatis. A total of 276 human immunodeficiency virus-infected men were included in the study. The prevalence of C. trachomatis infection was 12% (95% confidence interval 8.1%-15.7%). The mean age of the participants was 34.63 (standard deviation 10.80) years. Of the 276 human immunodeficiency virus-infected men, 93 (56.2%) had more than one sexual partner in the past year and 105 (38.0%) reported having their first sexual intercourse under the age of 15 years. Men having sex with men and bisexuals amounted to 61.2% of the studied population. A total of 71.7% had received human immunodeficiency virus diagnosis in the last three years and 55.1% were using antiretroviral therapy. Factors associated with C. trachomatis infection in the logistic model were being single (p<0.034), men having sex with men (p<0.021), and having previous sexually transmitted diseases (p<0.001). The high prevalence of C. trachomatis infection among human immunodeficiency virus-infected men highlights that screening human immunodeficiency virus-infected men for C. trachomatis, especially among men having sex with men, is paramount to control the spread of C. trachomatis infection.

    To determine if patients of a dentist with the acquired immunodeficiency syndrome (AIDS) became infected with human immunodeficiency virus (HIV) during their dental care and, if so, to identify possible mechanisms of transmission. Retrospective epidemiologic follow-up of the dentist, his office practice, and his former patients. The practice of a dentist with AIDS in Florida. A dentist with AIDS, his health care providers and employees, and former patients of the dentist, including eight HIV-infected patients. Identification of risks for HIV transmission (if present), degree of genetic relatedness of the viruses, and identification of infection control and other office practices. Five of the eight HIV-infected patients had no confirmed exposures to HIV other than the dental practice and were infected with HIV strains that were closely related to those of the dentist. Each of the five had invasive dental procedures, done by the dentist after he was diagnosed with AIDS. Four of these five patients shared visit days (P greater than 0.2). Breaches in infection control and other dental office practices to explain these transmissions could not be identified. Although the specific incident that resulted in HIV transmission to these patients remains uncertain, the epidemiologic evidence supports direct dentist-to-patient transmission rather than a patient-to-patient route.

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

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

    Full Text Available Gastrointestinal (GI opportunistic infections (OIs are commonly encountered at various stages of human immunodeficiency virus (HIV disease. In view of the suppressive nature of the virus and the direct contact with the environment, the GI tract is readily accessible and is a common site for clinical expression of HIV. The subject is presented based on information obtained by electronic searches of peer-reviewed articles in medical journals, Cochrane reviews and PubMed sources. The spectrum of GI OIs ranges from oral lesions of Candidiasis, various lesions of viral infections, hepatobiliary lesions, pancreatitis and anorectal lesions. The manifestations of the disease depend on the level of immunosuppression, as determined by the CD4 counts. The advent of highly active antiretroviral therapy has altered the pattern of presentation, resorting mainly to features of antimicrobial-associated colitis and side effects of antiretroviral drugs. The diagnosis of GI OIs in HIV/ acquired immunodeficiency syndrome patients is usually straightforward. However, subtle presentations require that the physicians should have a high index of suspicion when given the setting of HIV infection.

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

    Full Text Available Primary immunodeficiency disorders are a heterogeneous group of genetic disorders, with different modes of inheritance, consisting of more than 100 different types. We constructed the DNA banking of primary immunodeficiency disorders for the first time in Iran. The DNA of 31 immunodeficient patients and their families (total of 92 samples were collected, as the first step for construction of DNA banking. DNA was isolated from whole blood by salting out method. Among our patients, Common variable immunodeficiency was the most common disorder, followed by X-linked agammaglobulinemia, Ataxia-telangiectasia, Chronic granulomatous disease, Severe combined immunodeficiency, Hyper IgM syndromes, and Leukocyte adhesion defects. DNA banking is a useful method for further detection of mutation in immunodeficient patients and prenatal diagnosis for presence or absence of the disorder in the fetus which can be confirmed by molecular genetics testing.

    effect of a novel compound (NS1643) that activates the rapid delayed-rectifier K+ current, I(Kr), in two rabbit models of acquired LQTS. METHODS AND RESULTS: We used two clinically relevant in vivo rabbit models of TdP in which we infused NS1643 or vehicle: (i) three-week atrioventricular block...... with ventricular bradypacing; (ii) dofetilide-induced I(Kr) inhibition in methoxamine-sensitized rabbits. In addition, we studied effects on ionic currents in cardiomyocytes with I(Kr) suppressed by bradycardia remodelling or dofetilide exposure. Bradypaced rabbits developed QT interval prolongation, spontaneous...... ventricular ectopy, and TdP. Infusion of NS1643 completely suppressed arrhythmic activity and shortened the QT interval; vehicle had no effect. NS1643 also suppressed ventricular tachyarrhythmias caused by infusion of dofetilide to methoxamine-sensitized rabbits, and reversed dofetilide-induced QT...

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

    Full Text Available The human immunodeficiency virus (HIV/ acquired immune deficiency syndrome (AIDS pandemic has pervasive effects on culture, economics, policy, and human development. All organs can be affected by complications of HIV/AIDS, including the eye. When sufficient resources are available and widespread antiretroviral resistance does not exist, the four available classes of antiretroviral agents - nucleoside/nucleotide reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, protease inhibitors, and fusion inhibitors - can be combined to provide highly active antiretroviral therapy (HAART. For many (not all patients, HAART converts an inexorably fatal disease into a chronic disease with a fairly good prognosis. Use of HAART often induces partial immune recovery, which has predominantly beneficial effects on ocular complications of AIDS. However, HAART-induced immune recovery sometimes results in immune recovery inflammatory syndromes, such as immune recovery uveitis. Use of HAART is the single most useful intervention for most patients with ocular complications of AIDS. However, specific ocular therapy is also critical to avoid blindness in the early months before immune recovery can occur, or if HAART is unavailable. Increasing availability of HAART worldwide shows great promise to alleviate one of the world′s greatest plagues. However, predictable secular trends in the AIDS epidemic make it likely that the number of cases of ocular complications of AIDS will increase substantially before they decrease. Ophthalmologists worldwide should be familiar with the diagnosis and management of cytomegalovirus retinitis - the most common ocular complication of AIDS - and should establish partnerships with physicians who are able to provide HAART. Research is needed to determine the optimal approach for managing cytomegalovirus retinitis in resource-constrained settings.

    The authors report two cases of unusual venous thrombosis associated with protein S deficiency in patients with the acquired immunodeficiency syndrome. The first case was a superior mesenteric vein thrombosis caused by HIV-1 infection associated with protein S deficiency in a 53-year-old patient. The second case was a cerebral venous thrombosis in a 34-year-old patient with HIV-1 and HIV-2 infections associated with protein S deficiency. None of the two patients were receiving antiretroviral therapy at the time of diagnosis. The evolution of thrombosis was favorable in both patients with heparin therapy and antivitamin K (AVK).

    We determined the prevalence of seven clinically important pathogens that cause sexually transmitted infections (STIs) (Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Trichomonas vaginalis, herpes simplex virus 1 [HSV-1], HSV-2, and Treponema pallidum), by using a multiplex polymerase chain reaction (M-PCR) in samples from Brazilian woman infected with human immunodeficiency virus 1 (HIV-1) and uninfected Brazilian women (controls). The M-PCR assay identified all STIs tested for and surprisingly, occurred association between the control and STIs. This association was probably caused by excellent HIV infection control and regular monitoring in these women established by public health strategies in Brazil to combat HIV/acquired immunodeficiency syndrome. Studies using this M-PCR in different populations may help to better elucidate the roles of STIs in several conditions.

  12. The role of monocyte-lineage cells in human immuno-deficiency virus persistence: mechanisms and progress

    2011-01-01

    Human immunodeficiency virus type 1 (HIV-1) persistence is a major barrier to the successful treatment and eradication of acquired immunodeficiency syndrome (AIDS). In addition to resting CD4+ T cells, a significant long-lived compartment of HIV-1 infection in vivo includes blood monocytes and tissue macrophages. Studying HIV-1 persistence in monocyte-lineage cells is critical because these cells are important HIV-1 target cells in vivo. Monocyte-lineage cells, including monocytes, dendritic cells (DCs) and macrophages, play a significant role in HIV-1 infection and transmission. These cells have been implicated as viral reservoirs that facilitate HIV-1 latency and persistence. A better understanding of HIV-1 interactions with monocyte-lineage cells can potentially aid in the development of new approaches for intervention. This minireview highlights the latest advances in understanding the role of monocyte-lineage cells in HIV-1 persistence and emphasizes new insights into the mechanisms underlying viral persistence.

  13. The application of root mean square electrocardiography (RMS ECG for the detection of acquired and congenital long QT syndrome.

    Robert L Lux

    Full Text Available BACKGROUND: Precise measurement of the QT interval is often hampered by difficulty determining the end of the low amplitude T wave. Root mean square electrocardiography (RMS ECG provides a novel alternative measure of ventricular repolarization. Experimental data have shown that the interval between the RMS ECG QRS and T wave peaks (RTPK closely reflects the mean ventricular action potential duration while the RMS T wave width (TW tracks the dispersion of repolarization timing. Here, we tested the precision of RMS ECG to assess ventricular repolarization in humans in the setting of drug-induced and congenital Long QT Syndrome (LQTS. METHODS: RMS ECG signals were derived from high-resolution 24 hour Holter monitor recordings from 68 subjects after receiving placebo and moxifloxacin and from standard 12 lead ECGs obtained in 97 subjects with LQTS and 97 age- and sex-matched controls. RTPK, QTRMS and RMS TW intervals were automatically measured using custom software and compared to traditional QT measures using lead II. RESULTS: All measures of repolarization were prolonged during moxifloxacin administration and in LQTS subjects, but the variance of RMS intervals was significantly smaller than traditional lead II measurements. TW was prolonged during moxifloxacin and in subjects with LQT-2, but not LQT-1 or LQT-3. CONCLUSION: These data validate the application of RMS ECG for the detection of drug-induced and congenital LQTS. RMS ECG measurements are more precise than the current standard of care lead II measurements.

    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.

    Full Text Available Restless Legs Syndrome (RLS is a prevalent but poorly understood disorder that ischaracterized by uncontrollable movements during sleep, resulting in sleep disturbance.Olfactory memory in Drosophila melanogaster has proven to be a useful tool for the study ofcognitive deficits caused by sleep disturbances, such as those seen in RLS. A recently generatedDrosophila model of RLS exhibited disturbed sleep patterns similar to those seen in humans withRLS. This research seeks to improve understanding of the relationship between cognitivefunctioning and sleep disturbances in a new model for RLS. Here, we tested learning andmemory in wild type and dBTBD9 mutant flies by Pavlovian olfactory conditioning, duringwhich a shock was paired with one of two odors. Flies were then placed in a T-maze with oneodor on either side, and successful associative learning was recorded when the flies chose theside with the unpaired odor. We hypothesized that due to disrupted sleep patterns, dBTBD9mutant flies would be unable to learn the shock-odor association. However, the current studyreports that the recently generated Drosophila model of RLS shows successful olfactorylearning, despite disturbed sleep patterns, with learning performance levels matching or betterthan wild type flies.

    Revertant somatic mosaicism has been described in an increasing number of genetic disorders including primary immunodeficiency diseases. Both back mutations leading to restoration of wild-type sequences and second-site mutations resulting in compensatory changes have been demonstrated in mosaic individuals. Recent studies identifying revertant somatic mosaicism caused by multiple independent genetic changes further support its frequent occurrence in primary immunodeficiency diseases. Revertant mosaicism acquires a particular clinical relevance because it may lead to selective growth advantage of the corrected cells, resulting in improvement of disease symptoms or atypical clinical presentations. This phenomenon also provides us unique opportunities to evaluate the biological effects of restored gene expression in different cell lineages. Here we review the recent findings of revertant somatic mosaicism in primary immunodeficiency diseases and discuss its clinical implications.

    Gene therapy of severe combined immunodeficiencies has been proven to be effective to provide sustained correction of the T cell immunodeficiencies. This has been achieved for 2 forms of SCID, i.e SCID-X1 (γc deficiency) and adenosine deaminase deficiency. Occurrence of gene toxicity generated by integration of first generation retroviral vectors, as observed in the SCID-X1 trials has led to replace these vectors by self inactivated (SIN) retro(or lenti) viruses that may provide equivalent efficacy with a better safety profile. Results of ongoing clinical studies in SCID as well as in other primary immunodeficiencies, such as the Wiskott Aldrich syndrome, will be thus very informative.

    In the recent past, the gene therapy field has witnessed a remarkable series of successes, many of which have involved primary immunodeficiency diseases, such as X-linked severe combined immunodeficiency, adenosine deaminase deficiency, chronic granulomatous disease, and Wiskott-Aldrich syndrome. While such progress has widened the choice of therapeutic options in some specific cases of primary immunodeficiency, much remains to be done to extend the geographical availability of such an advanced approach and to increase the number of diseases that can be targeted. At the same time, emerging technologies are stimulating intensive investigations that may lead to the application of precise genetic editing as the next form of gene therapy for these and other human genetic diseases.

      We report three cases of Landau-Kleffner syndrome (LKS) in children (two females, one male) in whom diagnosis was delayed because the sleep electroencephalography (EEG) was initially normal.   Case histories including EEG, positron emission tomography findings, and long-term outcome were reviewed.   Auditory agnosia occurred between the age of 2 years and 3 years 6 months, after a period of normal language development. Initial awake and sleep EEG, recorded weeks to months after the onset of language regression, during a nap period in two cases and during a full night of sleep in the third case, was normal. Repeat EEG between 2 months and 2 years later showed epileptiform discharges during wakefulness and strongly activated by sleep, with a pattern of continuous spike-waves during slow-wave sleep in two patients. Patients were diagnosed with LKS and treated with various antiepileptic regimens, including corticosteroids. One patient in whom EEG became normal on hydrocortisone is making significant recovery. The other two patients did not exhibit a sustained response to treatment and remained severely impaired.   Sleep EEG may be normal in the early phase of acquired auditory agnosia. EEG should be repeated frequently in individuals in whom a firm clinical diagnosis is made to facilitate early treatment. © The Authors.

    Full Text Available In September 1985, a prospective study was initiated to monitor the occurrence of occupational exposures to human immunodeficiency virus (HIV-infected blood and body fluids in Canada. This program was coordinated by the Federal Centre for acquired immune deficiency syndrome (AIDS (now the Division of HIV/AIDS Epidemiology at the Laboratory Centre for Disease Control. The objective was to determine the risk to workers of acquiring HIV infection as a result of exposure to HIV-infected blood and other body fluids. To be eligible, a worker must have sustained a documented parenteral, mucous membrane or skin contact exposure to blood or body fluids from an HIV-infected person. A baseline specimen was collected within a week of the exposure and then at six weeks, 12 weeks, six months and 12 months. Information concerning the type of exposure, precautions used and post exposure treatment was submitted to the Federal Centre for AIDS on standard data collection forms. All information was anonymous, identified only by a code number. Guidelines for counselling an exposed employee were provided with enrollment material. As of July 29, 1991, 414 employees have been included in the study. Two hundred and thirty-seven of the 414 exposures (57% were needlestick injuries of which 167 (70% were sustained by nurses. Other exposures consisted of open wound contamination, eye splashes, scalpel wounds and skin contact with blood and body fluids. To date, there have been no seroconversions among workers enrolled in the surveillance program.

    This study represents the first epidemiological study based on the national registry of primary immunodeficiencies (PID) in Korea. Patient data were collected from 23 major hospitals. A total of 152 patients with PID (under 19 yr of age), who were observed from 2001 to 2005, have been entered in this registry. The period prevalence of PID in Korea in 2005 is 11.25 per million children. The following frequencies were found: antibody deficiencies, 53.3% (n = 81), phagocytic disorders, 28.9% (n = 44); combined immunodeficiencies, 13.2% (n = 20); and T cell deficiencies, 4.6% (n = 7). Congenital agammaglobulinemia (n = 21) and selective IgA deficiency (n = 21) were the most frequently reported antibody deficiency. Other reported deficiencies were common variable immunodeficiencies (n = 16), X-linked agammaglobulinemia (n = 15), IgG subclass deficiency (n = 4). Phagocytic disorder was mostly chronic granulomatous disease. A small number of patients with Wiskott-Aldrich syndrome, hyper-IgE syndrome, and severe combined immunodeficiency were also registered. Overall, the most common first manifestation was pneumonia. This study provides data that permit a more accurate estimation PID patients in Korea.

    2015-01-01

    Primary immunodeficiencies (PIDs) have represented a paradigmatic model for successes and pitfalls of hematopoietic stem cells gene therapy. First clinical trials performed with gamma retroviral vectors (γ-RV) for adenosine deaminase severe combined immunodeficiency (ADA-SCID), X-linked SCID (SCID-X1), and Wiskott–Aldrich syndrome (WAS) showed that gene therapy is a valid therapeutic option in patients lacking an HLA-identical donor. No insertional mutagenesis events have been observed in mor...

    Full Text Available We report the updated classification of primary immunodeficiencies compiled by the Expert Committee of the International Union of Immunological Societies. In comparison to the previous version, more than 30 new gene defects are reported in this updated version. In addition we have added a table of acquired defects that are phenocopies of primary immunodeficiencies. For each disorder, the key clinical and laboratory features are provided. This classification is the most up to date catalogue of all known primary immunodeficiencies and acts as a current reference of the knowledge of these conditions and is an important aid for the molecular diagnosis of patients with these rare diseases.

    Severe combined immunodeficiency includes a group of diseases characterized by different inherited immunological defects. A 4-month-old girl diagnosed with Omenn syndrome, a subtype of severe combined immunodeficiency presenting with generalized erythroderma, was referred to our hospital for an allogeneic stem cell transplantation. Days before transplantation, she developed hyperpigmented macules that increased in number in the following months. As the erythroderma resolved after transplantation, diffuse hypopigmentation was simultaneously noted together with the expansion of hyperpigmented lesions. Cutaneous biopsy samples were taken at different moments, showing features of Omenn syndrome at first, and 2 months later changes consistent with hypopigmentation and repigmentation were observed. Although pigmentary disorders are rarely described in this context, these must be taken into account as a possible alternative diagnosis to graft-versus-host disease and toxicoderma in immunosuppressed patients.

    Full Text Available Partial albinism with immunodeficiency is a rare and fatal immunologic disorder characterized by pigmentary dilution and variable cellular immunodeficiency. It was initially described in 1978. Primary abnormalities included silvery grayish sheen to the hair, large pigment agglomerations in hair shafts and an abundance of mature melanosomes in melanocytes, with reduced pigmentation of adjacent keratinocytes. We describe a child with Griscelli syndrome who presented with hepatitis, pancytopenia and silvery hair. The diagnosis was confirmed by microscopic skin and hair examination.

    Autoinflammatory diseases encompass a group of inflammatory diseases that are non-infectious, non-allergic, non-autoimmune and non-immunodeficient. The term was initially coined for a small group of familial periodic fever syndromes of which familial Mediterranean fever (FMF) is the most common and best known. Genetic and molecular analyses demonstrated for the majority of these diseases an impairment of inflammasomes to cause an increased activity of an interleukin-1-dependent inflammatory response. Over the last years an increasing number of either rare hereditary syndromes or acquired common diseases could be summarized under the designation of autoinflammatory disease, thus creating an emerging new rubric of inflammatory diseases. Many of them display cutaneous manifestations as both concomitant or more rarely main symptoms. To name some of them like erysipelas-like erythema in FMF; urticaria-like rashes in tumor necrosis factor receptor 1- or cryopyrin-associated periodic syndromes (TRAPS, CAPS), hyperimmunoglobulin D syndrome (HIDS) or Schnitzler syndrome; pyoderma gangrenosum and acne in PAPA syndrome; or behçetoid aphthous ulcerations in HIDS and PFAPA syndrome. Based on the new insights into pathogenesis one increasingly realizes the good response of these diseases to IL-1 antagonist therapies.

    Full Text Available Acquired methemoglobinaemia is a relatively rare condition and, therefore infrequently encountered in acute medical practice. Suspicion of the condition may be triggered when the measured PaO2 is ‘out of keeping’ with the oxygen saturations that are discovered with pulse oximetry. We describe two separate cases of acquired methemoglobinaemia secondary to the recreational use of alkyl nitrites (’poppers’. The patients presented at separate times to two different teaching hospitals in London, UK. The similarity of these cases has led the authors to conclude that a raised awareness of this potentially fatal condition, and its association with a widely-available recreational drug, is necessary to ensure a correct and timely diagnosis.

    Acquired immune deficiency syndrome (AIDS) complicated with intestinal tuberculosis is rarely reported. Due to lack of typical clinical and endoscopic characteristics,it is easy to be misdiagnosed. In this article,we report and analyze a case of AIDS patient with intestinal tuberculosis,which might be helpful to raise awareness and reduce misdiagnosis or mistreatment.%文献报道获得性免疫缺陷综合征(acquired immune deficiency syndrome,AIDS)合并肠结核很少,临床表现和内镜特点不典型,易误诊.本文对1例手术证实为合并肠结核的AIDS病例进行分析,旨在提高对AIDS继发肠病的诊断认识,减少误诊误治.

  18. Epstein-Barr virus immediate-early gene product trans-activates gene expression from the human immunodeficiency virus long terminal repeat

    Acquired immunodeficiency syndrome patients are frequently coinfected with Epstein-Barr virus (EBV). In this report, the authors demonstrate that an EBV immediate-early gene product, BamHI MLF1, stimulates expression of the bacterial chloramphenicol acetyltransferase (CAT) gene linked to the human immunodeficiency virus (HIV) promoter. The HIV promoter sequences necessary for trans-activation by EBV do not include the tat-responsive sequences. In addition, in contrast to the other herpesvirus trans-activators previously studied, the EBV BamHI MLF1 gene product appears to function in part by a posttranscriptional mechanism, since it increases pHIV-CAT protein activity more than it increases HIV-CAT mRNA. This ability of an EBV gene product to activate HIV gene expression may have biologic consequences in persons coinfected with both viruses.

  20. Current human immunodeficiency virus epidemic and its response in China

    The first patient with acquired immunodeficiency syndrome (AIDS) was identified in 1985; since then, as of October 31, 2010, a total accumulative number of 370 000 patients with human immunodeficiency virus (HIV)/AIDS have been reported. The estimated number of patients living with HIV (PLHIV) in China was 740 000 in 2009. Although China is still a low-HIV prevalence region (rate of 0.057%), the epidemic has spread more widely from the high-risk groups to the general population. This paper covers five topics of importance, i.e., current trends of the HIV epidemic; HIV-1 subtype diversity; emergence of HIV drug resistance (HIVDR); the country's response to the disease; and future challenges and additional actions needed. This paper emphasizes sexual transmission as the predominant route of transmission and it being spread more frequently among men who have sex with men; the epidemic being concentrated over particular areas in China. We also discuss the fact that diverse HIV-1 subtypes have been found throughout the entire country and that recombinant subtypes became predominant. We also explore other topics such as the possibility of HIVDR, including primary and secondary resistance, with the use of free highly active anti-retroviral therapy (HAART); the integrated strategy of HIVDR surveillance and individual clinical HIVDR testing as a new attempt in China. For many years both policy-makers and professionals (including non-governmental organizations) have expressed strong commitment to prevention, control, and care of HIV/sexual transmission infection (STI), promoted the research and conducted different actions to slow the rising trend of the HIV epidemics. Although China is facing many challenges, its citizens need to be persistent on continuing the campaign of the State Council titled "Information of Strengthening Work on Prevention and Control of AIDS".
