Prevalence of intestinal parasitic infections in patients with acquired immunodeficiency syndrome in Brazil
AbstractObjectives: To evaluate the prevalence of intestinal parasitic infections and to investigate the possible associations of clinical status and laboratory findings with the different parasites found in stool samples.Methods: Each patient was provided with one standard fecal collection vial containing 10% formalin for detecting ova, larvae, and cysts. To detect Cryptosporidium parvum and Isospora belli, the acid-fast Kinyoun stain and fluorescent auramine-rhodamine stain were used.Results: A total of 200 patients with acquired immunodeficiency syndrome participated in this study; 40% were infected with at least one pathogenic species. The total prevalence of parasites was 16% for Giardia lamblia, 13% for Entamoeba coli, 7% for Cryptosporidium parvum, 3.5% for Endolimax nana, 2.5% for Ascaris lumbricoides, 2.5% for Strongyloides stercoralis, 2% for Isospora belli, and 0.5% for Blastocystis hominis. Results showed that diarrhea was significantly associated with cryptosporidiosis, giardiasis, and isosporiasis. However, no association was observed between the CD4+ cell counts and the manifestation of any particular parasite.Conclusions: The data support the value of standard fecal examinations in human immunodeficiency virus-infected patients, even in the absence of diarrhea, since these examinations easily can be performed, with low costs, and frequently disclose treatable conditions
Perfil lipÃdico, fatores de risco cardiovascular e sÃndrome metabólica em um grupo de pacientes com AIDS
Nutritional and clinical status, and dietary patterns of people living with HIV/AIDS in ambulatory care in Sao Paulo, Brazil
INTRODUÇÃO: Atualmente, a abordagem nutricional desempenha papel essencial no tratamento de pessoas que vivem com HIV/aids, particularmente no caso de alterações metabólicas pelo uso da terapia antirretroviral (TARV) que podem estar associadas ao maior risco de doenças cardiovasculares (DCV). OBJETIVO: Caracterizar o estado nutricional, clÃnico e a qualidade da dieta de pessoas que vivem com HIV/aids. METODOLOGIA: Trata-se de um estudo transversal envolvendo pessoas que vivem com HIV/aids em atendimento na rede de serviços especializados no municÃpio de São Paulo. Os usuários desta rede, em uso ou não de TARV, foram recrutados no perÃodo de dezembro de 2004 a maio de 2006, durante consultas de rotina. Foram coletados dados sociodemográficos, clÃnicos, bioquÃmicos, antropométricos e dietéticos. A qualidade da dieta foi avaliada segundo escores de padrão de consumo predominantemente "não protetor" e "protetor" para DCV. RESULTADOS: A amostra foi constituÃda por 238 pacientes em TARV e 76 sem TARV. A média dos nÃveis de colesterol total, triglicérides e glicemia foram maiores no grupo TARV (p < 0,001). A maior parte dos participantes do estudo, com e sem TARV, apresentava-se eutrófica, com média de Ãndice de massa corporal 24,4 (± 4,3) e 24,3 (± 3,5) kg/m², respectivamente. A relação cintura-quadril foi maior entre homens em TARV que entre aqueles sem TARV (0,90 ± 0,06 versus 0,87 ± 0,05) (p < 0,001). O grupo em TARV apresentou média de escores indicativa de maior consumo de alimentos "não protetores" para DCV (p = 0,001). CONCLUSÃO: Foram evidenciadas condições nutricionais e metabólicas indesejáveis entre aqueles em TARV, predisponentes ao risco de DCV. É apontada a necessidade de direcionamento das intervenções em saúde a pessoas que vivem com HIV/aids, para o controle dos fatores associados a essas doenças antes do desfecho final.INTRODUCTION: Nutrition currently plays a key role in the treatment of people living with HIV/AIDS (PLHA), especially in the case of metabolic alterations due to highly active antiretroviral therapy (HAART), which could be related to cardiovascular diseases (CD). OBJECTIVE: to describe the nutritional and clinical status, and the quality of diet of PLHA. METHODS: It is a cross-sectional study involving a network of ambulatory care facilities for PLHA in the city of São Paulo, Brazil. Patients, in use of HAART or not, were selected from December 2004 to may 2006, through routine clinic visits. We collected: socio-demographic, clinical, biochemical, anthropometric measures and dietary data. Diet quality was evaluated according to a "protecting" or "non-protecting" pattern of consumption scores for CD. RESULTS: The sample had 238 patients on HAART and 76 without treatment. Mean serum levels of total cholesterol, triglycerides and glucose were higher in the HAART group (p < 0.001). The majority of patients of both the treated and untreated group were eutrophic with a mean body mass index (BMI) of 24.4 (± 4.3) kg/m² and 24.3 (± 3.5), respectively. The waist-hip ratio was higher among men on HAART (0.90 ± 0.06 versus 0.87±0.05) (p < 0.001). The HAART group showed a mean food pattern score indicating a higher consumption of "non-protecting" foods for CD (p = 0.001). CONCLUSION: The results showed undesired nutritional and metabolic conditions among patients on HAART associated with CD. It is necessary to manage health intervention programs for PLHA in order to control cardiovascular risk factors before final outcomes.UNESCO - Ministério da Saúd
