| ABSTRACT This study aimed to identify the 516 G>T polymorphism of the CYP2B6 gene and evaluate its influence on central nervous system (CNS) side effect development in HIV-positive individuals undergoing Efavirenz (EFV) treatment in a population from southern Brazil. Additionally, we performed a survey on the clinical and epidemiological characteristics of our sample. In addition to medical records evaluation, whole blood of 89 individuals was analyzed for viral load, T lymphocyte count (CD4+ and CD8+), and the polymorphism. Considering the side effects of the CNS reported by individuals but without considering the genetic variables, no statistically significant association was noted between the adverse effects and the antiretroviral treatment... |

| We examined the characteristics of the AIDS epidemic in the northeastern region of Brazil, comparing it to the epidemic in Brazil as a whole, and to the state of São Paulo, with respect to the temporal evolution of morbidity and mortality during the period 1990 to 1999, using information from communicable disease reports and mortality records. Since 1996, the incidence rate of AIDS in adults in Brazil as a whole and in São Paulo has been showing a trend towards stability, whereas in the Brazilian northeast the incidence rates of the disease continue to grow. In the northeast, sexual transmission is responsible for more than 80% of cases, injectable drug users (IDU) comprising only a small percentage of cases. There is a greater incidence of AIDS among... |

| A patient with HIV infection developed the first episode of AIDS-defining opportunism (severe Candida albicans esophagitis) with an underlying CD4+ lymphocyte count of 1,025 cells/µL. After treatment with a highly active antiretroviral therapy (HAART), taken with insufficient compliance and leaving a residual viral load, our patient suffered from two relapses of esophageal candidiasis, which occurred three months and seven years later, when his CD4+ lymphocyte count was 930 and 439 cells/µL, respectively, and a viral load slightly above 10(4) copies/mL was still present. Also in the HAART era, Candida esophagitis remains one of the most common AIDS-defining diseases, but a presentation with a concurrent CD4+ count above 1,000 cells/µL remains a rare... |

| ABSTRACT Antiretroviral therapy (ART) has modified the outcome of patients with HIV infection, providing virological control and reducing mortality. However, there are several reasons as to why patients may discontinue their antiretroviral therapy, with adverse events being one of the main reasons reported in the literature. This is a case-control nested in a cohort of people living with HIV/AIDS, conducted to identify the incidence of ART modification due to adverse events and the associated factors, in two referral services in Recife, Brazil, between 2011 and 2014. Of the modifications occurred in the first year of ART, 25.7% were driven by adverse events. The median time elapsed between initiating ART and the first modification due to adverse events was... |

| It is currently recommended that antiretroviral prophylaxis to prevent mother-to-child transmission (MTCT) of HIV be initiated at 14 weeks of gestation. However, the relevance of early-gestation HIV viral load level for intrauterine MTCT is unknown. The objective of this study was to determine the relationship between prenatal maternal viral load and intrauterine MTCT. Records of HIV-infected pregnant women in two centers in Brazil, from 1999 to 2004 were analyzed. Three pregnancy periods were considered: earlier than 14 weeks, 14 to 27 6/7 weeks, and 28 weeks of gestation or more. Peripartum HIV exposure was also computed. Maximum viral load in each period was the measure of HIV exposure. Four hundred fifty-seven HIV-infected pregnant women were... |

| ABSTRACT Early initiation of antiretroviral therapy increases the likelihood of effective immune restoration, quality of life, and greater life expectancy for HIV-infected individuals. We evaluated the evolution of mean CD4+ cells count at diagnosis of HIV/AIDS in Salvador, Brazil from 2002 to 2015. We identified HIV/AIDS patients older than 18 years with diagnosis of HIV infection from 2002 to 2015, who had their first laboratory evaluation at Complexo Hospitalar Prof. Edgard Santos, Federal University of Bahia. Initial mean CD4+ cells count and age, over time were evaluated. A total of 1801 patients randomly selected individuals were included in the analysis. Overall mean CD4+ count at diagnosis in the whole period was 279 ± 265, varying from 191 in 2015... |

| INTRODUCTION: Studies disagree as to whether there is a greater prevalence of hypertension among HIV/AIDS patients and the role of antiretroviral therapy. OBJECTIVE: Evaluate the prevalence of hypertension and risk factors in a cohort of HIV-infected patients, with emphasis on antiretroviral therapy. METHOD: Case-control study conducted at baseline of a cohort, between June/2007 and December/2008 in Pernambuco/Brazil. Blood pressure was classified as normal, prehypertension, and hypertension. RESULTS: Of 958 patients, 245 (25.6%) had hypertension (cases), 325 (33.9%) had prehypertension, and 388 (40.5%) were normotensive (controls). Comparison between hypertensive and normotensive patients showed that traditional factors, such as age > 40 (OR = 3.06, CI... |

| Forty-nine AIDS patients, most of who were antiretroviral therapy (ARV) naïve, with active tuberculosis, were treated with Rifampin 600mg, Isoniazid 400mg and Pirazinamide 2g daily. They also received ARV, consisting of Efavirenz (600mg/day) plus 2 NRTIs. All patients were prospectively followed for at least 24 months. Baselines were: male/female ratio 2:1, mean age 34.7 ± 9.4 yrs; weight 51 ± 9.0 kg, viral load 5.6 ± 0.6 logs, CD4 cell count 101 ± 128 cells/ mm³. Follow up mean values of data logs of VL and CD4+ cell /mm³ counts were: VL 1.7 and CD4+ 265; VL 1.3 and CD4+ 251; VL 1.4 and CD4+ 326 at 6, 12 and 24 months, respectively. Weight gain changes were: 5 ± 9.9 ± 12 and 21 ± 16 kg respectively at 6, 12 and 24 months. A non-concomitant ARV regimen was... |

| Abstract Introduction Advances in the treatment of HIV infection in the last decades have increased life expectancy of these patients and raise the question of what kind of effect chronic infection and its treatment might exert on the behavior of age-related conditions such as neurodegenerative diseases. Patient data We performed a retrospective analysis of patients’ records to assess the frequency of the association between HIV infection and parkinsonian symptoms in our hospital population. Among 249 records we identified four individuals with reported parkinsonian symptoms initiated after HIV diagnosis. Three of them had no other identifiable cause of secondary parkinsonism. All had symptom onset before the age of 60. Based on this study sample one... |

| Treatment of HIV-1 infection with highly active antiretroviral therapy has led to sustained viral suppression in the plasma in a large number of children. However, studies have suggested that the integrated provirus in resting CD4+ T lymphocytes could be a source of reactivatable virus and maintain drug-resistant virus. We evaluated the resistance-related mutations in children receiving antiretroviral therapy with prolonged viral suppression. Thirty-two peripheral blood mononuclear cell samples from 16 children with viral loads that had been below detection limits for at least 12 months were obtained at two different time points and the DNAs sequenced. The median CD4 cell count was 1,016 cells/mm³ (347-2,588) and 938 cells/mm³ (440-3,038) at the first and... |
