Provedor de dados: 55
Autores: Ricci,Gabriela; Netto,Eduardo Martins; Luz,Estela; Rodamilans,Cynthia; Brites,Carlos.
Abstract  Background Successful treatment of HIV-positive children requires a high level of adherence (at least 95%) to highly active antiretroviral therapy. Adherence is influenced by factors related to the child and caregivers.  Objectives To evaluate children and caregivers characteristics associated to children's adherence.  Methods Cross-sectional study, from September 2013 to June 2015, comprising a sample of caregivers of perinatally HIV-infected children, in the age group of 1–12 years, under antiretroviral therapy for at least 6 months and on follow-up in two AIDS reference centers in Salvador, Bahia. Caregiver self-reports were the sole source of 4 days adherence and sociodemographic information. Study participants who reported an intake &gt;95%...

Autores: Souza,Breno Frederico de Carvalho Dominguez; Drexler,Jan Felix; Lima,Renato Santos de; Rosário,Mila de Oliveira Hughes Veiga do; Netto,Eduardo Martins.
Introduction:The human hepatitis B virus causes acute and chronic hepatitis and is considered one of the most serious human health issues by the World Health Organization, causing thousands of deaths per year. There are similar viruses belonging to the Hepadnaviridae family that infect non-human primates and other mammals as well as some birds. The majority of non-human primate virus isolates were phylogenetically close to the human hepatitis B virus, but like the human genotypes, the origins of these viruses remain controversial. However, there is a possibility that human hepatitis B virus originated in primates. Knowing whether these viruses might be common to humans and primates is crucial in order to reduce the risk to humans.Objective:To review the...

Evaluation of the genotypic pattern of HIV-1 resistance in AIDS patients failing antiretroviral therapy
Provedor de dados: 55
Autores: Bahia,Fabianna; Pedroso,Célia; Netto,Eduardo Martins; Figueiredo,Ricardo; Pinto Neto,Lauro; Brites,Carlos.
We analyzed the first 96 patients tested for HIV resistance to antiretroviral therapy in three Brazilian states. The HIV-1 reverse transcriptase (RT) and protease (PR) were sequenced by using the ABI ViroSeq system. The drugs previously used for each patient were recorded and correlated with the mutations found in the samples. Viral load (VL) and CD4 count were also recorded. Only one patient had the wild type sequence. The most prevalent mutations were: 184V (59%), 41L (47.9%), 63P (53%), 215Y (50%), 36I (46%), 10I (35%), 67N (42%), 77I (37%), 90M (36%) and 210W (33%). A positive correlation between the number of previously used ARVs and the number of mutations was observed (p&lt;0.05). Associations between mutations and ARV drugs were identified at...

Evaluating total lymphocyte counts as a substitute for CD4 counts in the follow up of AIDS patients
Provedor de dados: 55
Autores: Angelo,Ana Luiza Dias; Angelo,Camila Dias; Torres,Alex José Leite; Ramos,André Maurício Costa; Lima,Márcia; Netto,Eduardo Martins; Brites,Carlos.
This study evaluated total lymphocyte count (TLC) as a substitute marker for CD4+ cell counts to identify patients who need prophylaxis against opportunistic infection (CD4 &lt; 200 cells/mm³) and patients with CD4 &lt; 350 cells/mm³ (Brazilian threshold value of CD4 count to define AIDS). We evaluated TLC and CD4+ cells count of 1,174 HIV-infected patients, in Salvador, Brazil, from May 2003 to September 2004. CD4+ cell counts were performed by flow cytometry, and TLC was measured with an automated hematological counter. The mean CD4 count was 430 cells/mm³ (range: 4 to 2,531 cells/mm³). Mean TLC was 1,900 cells/mm³ (range: 300 to 6,200 cells/mm³). Using a threshold value of 1,000 cells/mm³ for TLC, the positive predictive value (PPV) was 77% for CD4 &lt;...

Use of new antiretroviral drugs and classes in Bahia, Brazil: a real life experience on salvage therapy of AIDS patients
Provedor de dados: 55
Autores: Brites,Carlos; Nóbrega,Isabella; Netto,Eduardo Martins.
ABSTRACTAntiretroviral therapy has significantly evolved in the last decade, with an increasing number of new drugs and classes. Currently, even heavily experienced patients can be successfully treated with new regimens. In Brazil, the recent incorporation of some new antiretroviral drugs made it possible to suppress HIV plasma viremia in most treated patients, with significant benefits in terms of quality of life and survival. However, little has been published on outcomes of patients under new drugs-based regimens. We reviewed the safety and efficacy of antiretroviral regimens using recently introduced drugs in Bahia. Our results confirm that patients using darunavir, raltegravir, enfuvirtide, or etravirine presented with a high rate of virological...

HLA-Bw4-B*57 and Cw*18 alleles are associated with plasma viral load modulation in HIV-1 infected individuals in Salvador, Brazil
Provedor de dados: 55

Host genetic factors play an important role in mediating resistance to HIV-1 infection and may modify the course of infection. HLA-B alleles (Bw4 epitope; B*27 and B*57) as well as killer cell immunoglobulin-like receptors have been associated with slow progression of HIV-1 infection. OBJECTIVE: To evaluate the association between serological epitopes HLA-Bw4 and HLA-Bw6 and prognostic markers in AIDS. METHODS: 147 HIV-infected individuals in Bahia, Northeast Brazil, were genotyped for HLA class I locus. HLA class I genotyping was performed by hybridization with sequence-specific oligonucleotide probes following amplification of the corresponding HLA-A, HLA-B and HLA-C genes. Statistical analysis was performed using Fisher's exact and ANOVA tests for...

Use of rhu-GM-CSF in pulmonary tuberculosis patients: results of a randomized clinical trial
Provedor de dados: 55
Autores: Pedral-Sampaio,Diana Brasil; Netto,Eduardo Martins; Brites,Carlos; Bandeira,Antonio Carlos; Guerra,Conceição; Barberin,Maria Goreth; Badaró,Roberto.
It has been postulated that deficient or incomplete clinical and/or microbiological response to tuberculosis treatment is associated with cell-mediated immunological dysfunction involving monocytes and macrophages. A phase 2 safety trial was conducted by treating patients with either recombinant human granulocyte-macrophage colony-stimulating factor (rhu-GM-CSF) or a placebo, both in combination with anti-tuberculosis chemotherapy. Thirty-one patients with documented pulmonary tuberculosis were treated with rifampin/isoniazid for six months, plus pyrazinamide for the first two months. At the beginning of treatment, rhu-GM-CSF (125µg/M²) was randomly assigned to 16 patients and injected subcutaneously twice weekly for four weeks; the other 15 patients...
