| The national blood transfusion policies have been changed significantly in recent years in Turkey. The purpose of this study was to determine the prevalence of HBV, HCV, and HIV in blood donors at the Red Crescent Center in Istanbul and to evaluate the effect of changes in the national blood transfusion policies on the prevalence of these infections. The screening results of 72695 blood donations at the Red Crescent Center in Istanbul between January and December 2007 were evaluated retrospectively. HBsAg, anti-HCV, and anti-HIV-1/2 were screened by microparticle enzyme immunoassay (MEIA) method. Samples found to be positive for anti-HIV 1/2 and anti-HCV were confirmed by Inno-Lia HCV Ab III and Inno-Lia HIV I/II Score, respectively. The seropositivity... |

| ABSTRACT Osteomyelitis due to Cryptococcus neoformans are described in mostly 10% of patients with disseminated cryptococcosis, being direct inoculation even more uncommon. We report the case of an HIV-infected patient with history of recurring itching on his scalp and repetitive local trauma. For eighteen months, he noticed a painful and slow growing lump on his scalp. He was submitted to an excisional biopsy of the lesion but no etiological diagnosis was identified. After this procedure, the post-surgical wound never completely healed. At admission, the patient presented nausea and headache for three days and an open orifice into his skull. Investigations confirmed meningitis and skull osteomyelitis caused by Cryptococcus neoformans. He was treated with... |

| The pandemic of HIV/AIDS continues to grow daily. Incident cases among women, intravenous drug users and ethnic minorities comprise the fastest growing segment of the HIV-infected population, and the number of HIV-infected individuals over the age of 50 is growing rapidly. Today, the central nervous system and the immune system are seen as main targets of HIV infection. Significant progress in the knowledge and treatment of AIDS has been obtained in recent years. The neurological manifestations directly related to HIV are acute viral meningitis, chronic meningitis, HIV-associated dementia (HAD), vacuolar myelopathy, and involvement of the peripheral nervous system. |

| 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... |

| There still is no cure for the acquired immunodeficiency syndrome (AIDS). Its etiologic agent is the human immunodeficiency virus (HIV), and transmission occurs through sexual relationships, contacts with blood, and vertically (mother to child). In this study, we sought to determine the prevalence of HIV among blood donors at a blood bank in Curitiba. We studied 213,666 blood donations made from March 1, 1992, to April 25, 1999. Each potential blood donor first answered a questionnaire, submitted to a clinical examination, and filled out a self-exclusion card. Blood was collected and analyzed only from the candidates approved by the first two criteria. Two tests were used to detect HIV: ELISA for screening, and Western-Blot for confirmation. The results... |

| ABSTRACT Background: Class I human leukocyte antigens, especially the molecules encoded at the B locus (HLA-B), are associated with AIDS progression risk. Different groups of HLA-B alleles have been associated to a protective effect or increasing susceptibility to HIV infection and are expressed from the earliest stages of gestation. Objective: The aim of this study was to evaluate which variants of HLA-B are associated with the risk of HIV vertical transmission in infected pregnant women and in their offspring, in a referral center in Salvador Bahia. Methods: We performed HLA-B genotyping in 52 HIV-infected mothers and their children exposed to HIV-1 during pregnancy (N = 65) in Salvador, Brazil. We compared the HLA-B alleles frequency in mothers,... |

| Enteroparasites are related to gastrointestinal alterations among patients with HIV/AIDS, some causing severe manifestations in the period before the institution of the highly active antiretroviral therapy (HAART). The prevalence of enteroparasitoses in patients with HIV/AIDS seen at two hospitals in Ceará , Brazil, was compared in the pre-HAART (Group 1; n = 482) and HAART (Group 2; n = 100) eras. Fecal parasitologic examinations (FPE) were performed using the direct, Lutz, Baermann-Moraes and modified Ziehl-Neelsen methods. The following parasites were detected in Groups 1 and 2, respectively: Strongyloides stercoralis - 30.1% and 11% (p<0.0001), Ascaris lumbricoides - 15.6% and 2% (p<0.0001), hookworms - 13.7% and 2% (p<0.0001), Trichuris... |

| OBJECTIVE: To study whether patients with HIV-1 associated lipodystrophy (LD) on highly active antiretroviral treatment (HAART) have more psychopathology and worse psychosocial adjustment than a similar group without this syndrome. METHODS: In a cross-sectional, observational study we compared 47 HIV-1 infected patients with LD (LD group) with 39 HIV-1 infected patients without LD (non-LD group). All participants were on HAART. The Beck Depression Inventory (BDI), the State and Trait Anxiety Inventory (STAI) and the Goldberg Health Questionnaire (GHQ-60) were administered. Levels of familial, work and social adjustment and adjustment to stressful events were evaluated in a semi-structured interview. Clinical information was extracted from the clinical... |

| We describe a case of a male patient, 38 years old, HIV-positive (most recent CD4 count about 259/mm³), with abdominal pain, nausea, vomiting, anorexia, weight loss, and vespertine high fever with chills. His hemogram showed normocytic and normochromic anemia, with a high erythrocyte sedimentation rate (ESR) and gross granulations in the neutrophils. Transaminases were normal. Bone marrow biopsy evidenced a chronic disease anemia pattern and a lack of infectious agents. Abdominal ultrasound examination showed a normal-size spleen, which exhibited heterogeneous parenchyma and multiple small hypoechoic images, together with small ascites, peripancreatic and para-aortic lymphadenopathy. These findings were confirmed by abdominal CT. The liver was normal in... |

| Abstract Abacavir can cause a multi-systemic hypersensitivity reaction (HSR) in 5-8% of the patients, which is related to HLA-B*57-01 allele. In Brazil, the HLA-B*57-01 screening test became available only in March 2018, several years after abacavir was in use. In this retrospective study we reviewed medical charts of all patients receiving an abacavir-containing regimen to evaluate the frequency of HSR in patients followed at a referral center in Salvador, Brazil. A total of 192 patients who received abacavir were identified, most male (67.1%), black or racially mixed (77.8%), and having diagnosis of a previous AIDS defining conditions (83.7%). Only one patient developed HSR (incidence: 0.52%). The main reasons for abacavir-containing antiretroviral... |
