Article: Rosuvastatin and ciprofibrate in the treatment of dyslipidemia in patients with HIV.
[show abstract] [hide abstract]
ABSTRACT: BACKGROUND: Dyslipidemia secondary to highly active antiretroviral therapy in patients with HIV is associated with a significant increase in cardiovascular morbidity and mortality due to atherosclerotic disease, requiring, thus, immediate and effective treatment. OBJECTIVE: To demonstrate the effectiveness and safety of rosuvastatin and ciprofibrate in the treatment of dyslipidemia associated with highly active antiretroviral therapy in patients with HIV. METHODS: Three hundred and forty-six patients with dyslipidemia underwent pharmacological treatment as follows: 200 patients with hypertriglyceridemia received ciprofibrate (Group I); 79 patients with hypercholesterolemia received rosuvastatin (Group II); and 67 patients with mixed dyslipidemia received ciprofibrate associated with rosuvastatin (Group III). The lipid profile was assessed before and after the lipid-lowering treatment, and the Wilcoxon test was used for statistical comparison. Liver transaminases and creatine phosphokinase were measured to assess liver and muscle toxicity. RESULTS: The serum concentrations of triglycerides and total cholesterol were significantly lower than those obtained before the lipid-lowering treatment in the three experimental groups (p < 0.002). A significant increase in HDL-cholesterol was observed in Groups I and III (p < 0.002). In Groups I and II, LDL-cholesterol was significantly lower (p < 0.001). None of the patients experienced elevations in transaminases or creatine phosphokinase to significantly toxic levels. CONCLUSION: The results of this study show that ciprofibrate and rosuvastatin or a combination of both can be considered an effective, safe and well-tolerated lipid-lowering treatment for patients with AIDS on highly active antiretroviral therapy.Arquivos brasileiros de cardiologia 10/2012; · 1.32 Impact Factor -
Article: Vulnerability to AIDS among the elderly in an urban center in central Brazil.
[show abstract] [hide abstract]
ABSTRACT: As the world population ages with an improved quality of life and sexual longevity, the prevalence of AIDS is rising among the elderly. The purpose of this study was to estimate the vulnerability to AIDS among individuals attending senior community centers in Campo Grande, Mato Grosso do Sul, Brazil. This descriptive, exploratory investigation included 329 subjects selected in a probabilistic manner. Individuals with scores on the Mini-Mental State Examination indicating cognitive impairment were excluded from the analyses. Barthel's and Lawton's functional assessment scales were applied. Interviews were conducted to evaluate the presence of cognitive and behavioral factors associated with HIV transmission. Most subjects were non-dependent, fell within the 60- to 69-year age bracket and were female. A majority of individuals reported having knowledge about AIDS and were aware that the elderly are vulnerable to the disease. More than a quarter (26.9%) of the sample reported previous HIV testing. No participants reported drug use, homosexual orientation, or alcohol abuse. A minority of participants reported using medication for erectile dysfunction. Casual and multiple partners accounted for 12% and 34% of reported intercourse experiences, respectively. Condom use was reported by 14% of respondents. Unprotected sex was the primary factor accounting for vulnerability to AIDS among the elderly.Clinics (São Paulo, Brazil) 01/2012; 67(1):19-25. · 1.59 Impact Factor -
Article: Hepatitis B virus infection in isolated Afro-Brazilian communities.
[show abstract] [hide abstract]
ABSTRACT: The prevalence and genotypes of hepatitis B virus (HBV) have distinct geographical distribution. In Brazil, some African-descendants have been maintained as small isolated communities since the slavery period. In this study, HBV infection among these communities of African origin was examined. Individuals (1,058) living in 12 communities were interviewed and serum samples screened for the presence of HBV markers. HBsAg-positive sera were tested for HBV DNA by PCR and positive samples were genotyped by restriction fragment length polymorphism (RFLP). The overall prevalence of HBV infection was 19.8% (95% CI: 17.5-22.3), ranging from 5.5% to 42.4%, depending on the communities studied. Multivariate analysis of risk factors showed that increasing age, family history of hepatitis, and sexual activity were associated significantly with this infection. HBsAg was detected in 23/1,058 (2.2%) individuals. HBV DNA was present in 2/2 of HBeAg-positive serum samples and in 18/21 (85.7%) anti-HBe-positive samples. All HBV isolates belonged to genotype A, subtype Aa. Three RFLP patterns were identified: AI (17 isolates), AIV (1 isolate), and AVI (2 isolates). These findings suggest a common introduction of HBV during the slave trade from Africa to Brazil.Journal of Medical Virology 11/2005; 77(2):188-93. · 2.82 Impact Factor -
Article: Paracoccidioidomicose: estudo clínico e epidemiológico de 422 casos observados no Estado de Mato Grosso do Sul
[show abstract] [hide abstract]
ABSTRACT: São descritas as características clínicas e epidemiológicas de 422 casos de paracoccidioidomicose atendidos no Hospital Universitário da Universidade Federal do Mato Grosso do Sul (Campo Grande, Mato Grosso do Sul, Brasil) no período de Janeiro de 1980 a Agosto de 1999. A média de idade foi de 43,4 anos e a proporção homem: mulher foi de 10:1. Quase metade (45,5%) dos doentes era trabalhadora rural no momento do diagnóstico. A forma aguda/subaguda (tipo juvenil)(15,4% dos casos) revelou-se com importante comprometimento do sistema fagocítico-monocitário, manifestado principalmente por adenomegalia (95,4%); hepatomegalia (40%); esplenomegalia (23,1%). A forma crônica (tipo adulto)(84,6% dos casos) apresentou-se com maiores proporções de lesões em orofaringe (66,4%); rouquidão (31,4%) e tosse (50,7%). Para o diagnóstico, foram utilizados o exame micológico direto em 365 pacientes e o histopatológico em 302, com positividade de 50,7% e 97,3%, respectivamente. O tratamento antifúngico preferencial foi a associação de sulfametoxazol e trimetoprim (co-trimoxazol), utilizado em 90,3% dos doentes. Seqüelas foram observadas em 30,3% e óbito em 7,6% dos casos.Revista da Sociedade Brasileira de Medicina Tropical. 01/2003; -
Article: Meningite paracoccidioidomicótica: relato de caso
[show abstract] [hide abstract]
ABSTRACT: O envolvimento do sistema nervoso central na paracoccidioidomicose tem sido pouco descrito na literatura, sendo rara sua apresentação sob a forma meníngea. Descreve-se o caso de um paciente de 23 anos que desenvolveu meningite paracoccidioidomicótica comprovada pela positividade do fungo na pesquisa direta e cultura do líquido cefaloraquidiano. Discute-se a apresentação da forma meníngea da paracoccidioidomicose, seu diagnóstico laboratorial e neurorradiológico. Destaca-se a importância da investigação rotineira do fungo.Arquivos de Neuro-Psiquiatria. 01/2002;
