| N-acetyl-L-cysteine (NAC) has been proposed as an additional therapeutic agent for AIDS patients because it reduces human immunodeficiency virus type 1 (HIV-1) replication in stimulated CD4+ lymphocytes, and it ameliorates immunological reactivity. In a randomized, 180-day, double-blind, placebo-controlled trial performed with HIV-infected patients classified as A2 and A3 according to the criteria of the Center for Disease Control and Prevention, we investigated the effects of oral administration of NAC on HIV-infected patients undergoing their first anti-retroviral therapy; viral load, CD4+ lymphocyte, lymphocyte viability and apoptosis, and TNF-alpha and IL-8 levels were determined. Sixteen patients who received anti-retroviral therapy plus a placebo... |

| 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... |

| The association of HIV infection and hepatitis C virus (HCV) infection often occurs because both viruses share the same transmission routes, increasing the possibility of HIV/HCV coinfection. World prevalence greater than 30% of coinfected cases is estimated, and it can reach 90% depending on the transmission route. With the aim of determining the frequency and profile of HIV/HCV coinfected patients, a descriptive analysis was carried out with patients with HIV/AIDS whose serology was positive for hepatitis C virus (HCV), cared for at the Fundação de Medicina Tropical do Amazonas from 2000 to 2007. In the present study, of the 2,653 AIDS cases notified in SINAN, 1,582 patients underwent serology test for hepatitis C, and a frequency of 4.42% (n = 70) of... |

| Several strategies aim at characterizing the AIDS epidemic in different parts of the world. Among these, the identification of recent HIV-1 infections using the recently described serologic testing algorithm for recent human immunodeficiency virus (HIV) seroconversion (STARHS) strategy was employed in four testing sites of the City of São Paulo Public Health Department (CSPPHD). Those identified as recently infected were invited to participate in a prospective clinical and laboratory evaluation study. We describe the establishment of the patient identification network and the success in enrolling the participants, as well as their clinical and laboratory characteristics. From May to December 2002, 6,443 persons were tested for HIV in the four participating... |

| The HIV, in hemotheraphy, may be transmitted by erythrocyte, platelets, crioprecipitated, frozen fresh plasma and possibly, by other blood components. Appropriate legislations for this new reality were elaborated normatizing the hemotheraphy practices in Brazil, creating a set of procedures and actions aiming at guaranteeing the quality of the blood, during, during the whole process. However, the residual risk remains, and it can be calculated as a product of the incidence and period of the immunological window. The objetive of the present study was to determine the rate of residual risk of the HIV blood transmission, in the blood donors from the Mountain Region of Santa Catarina. In order to calculate the residual risk of the HIV markers, 4,857 donors of... |

| The increase in survival rates of patients affected by AIDS is associated with physical disabilities that can compromise their functional independence. We examined the degree and types of disabilities in hospitalized AIDS patients , as well the clinical and immunological parameters associated with disability. The lowered functional status was associated with increased time since AIDS had been diagnosed, with complaints of weakness, and with the involvement of more than one set of systems in the definition of AIDS. The inability to perform daily living activities was associated with higher viral loads (log) c/mL, lower CD4+/mL and CD4+/CD8+ ratios, and with involvement of the central nervous system, in the cause of hospitalization. Both the inability to... |

| Human immunodeficiency virus (HIV) and intestinal parasites are common in Brazil. Previous studies have shown that infection with Strongyloides stercoralis is frequently associated with HIV infection. Strongyloidiasis is difficult to diagnosis and stool examination with conventional techniques fails to detect the helminth larvae. We made a prospective study, to test the efficacy of the agar plate technique to detect S. stercoralis in 211 HIV-positive patients and 213 HIV-negative patients in the city of Itajaí, Brazil, between September 2001 and June 2002. The feces samples of these patients were processed and analyzed according to the following methods: Lutz, formalin ethyl acetate, Baermann, Harada-Mori and agar plate culture. HIV-positive patients were... |

| Wage-differentials by education of men and women are examined from African household surveys to suggest private wage returns to schooling. It is commonly asserted that returns are highest at primary school levels and decrease at secondary and postsecondary levels, whereas private returns in six African countries are today highest at the secondary and post secondary levels, and rates are similar for women as for men. The large public subsidies for postsecondary education in Africa, therefore, are not needed to motivate students to enroll, and those who have in the past enrolled in these levels of education are disproportionately from the better-educated families. Higher education in Africa could be more efficient and more equitably distributed if the... |

| Abstract Background Development of drug-resistance mutations is the main cause of failure in antiretroviral therapy. In Brazil, there is scarce information on resistance pattern for patients failing antiretroviral therapy. Objectives To define the HIV mutational profile associated with drug resistance in Brazilian patients from 5 large cities, after first, second or further failures to antiretroviral therapy. Methods We reviewed genotyping results of 1520 patients failing therapy in five Brazilian cities. Frequency of mutations, mean number of active drugs, viral susceptibility to each antiretrovirals drug, and regional differences were assessed. Results Mean time of antiretrovirals use was 22.7 ± 41.1 months. Mean pre-genotyping viral load was 4.2 ±... |

| This study evaluates clinical, virological and immunological responses to antiretroviral (ARV) therapy based on Lopinavir/ritonovir (LPV/r) in previously protease -inhibitor-experienced children. The study included 29 Brazilian children (median age = 5.91 years) who had failed previous ARV therapy and had begun a regimen based on LPV/r. At 12 months follow-up, a good virological response to LPV/r therapy was defined as achieving an undetectable viral load or as a decrease in plasma HIV RNA levels to > 1 log. A good immunological response was defined as an increase in CD4+ cell count from baseline sufficient to attain a better CDC immune stage classification. The number of infectious episodes 12 months before and 12 months after beginning LPV/r was... |

| ABSTRACT Highly active antiretroviral therapy (HAART) has significantly improved survival of people living with HIV/Aids (PLWHA). However, poor treatment adherence to HAART and other problems, still cause therapy failure and contribute to increased morbidity and mortality of PLWHA. In this retrospective cohort study (2013-2015), we sought to evaluate the factors associated with mortality of PLWHA failing HAART in 2013, who were receiving care at a reference center for sexually transmitted diseases (STD) and HIV/AIDS. A total of 165 individuals over 18 years of age who were failing antiretroviral therapy were evaluated. In two-year follow-up, 19 (11.5%) deaths were documented. There were a significant association between mortality and report of illicit drug... |

| Infection with both Human Immunodeficiency Virus (HIV) and Mycobacterium tuberculosis is currently the world's leading cause of death due to infectious agents. We evaluated factors related to the development of tuberculosis (TB) in HIV-infected patients who were being treated at an infectious diseases hospital in Fortaleza, Ceará, Brazil. From January 2004 to December 2005, we made an epidemiological study through the analysis of the medical records of 171 patients, who were diagnosed as having both HIV and tuberculosis. Among these co-infected patients, most (81%, p=0.0006) were male. Co-infection was more frequent (87.8%) among patients over 40 years of age and those with lower educational levels (less than eight years of schooling). Forty-one percent of... |
