ABSTRACT
OBJECTIVE: Recent evidence suggests that non-alcoholic fatty liver disease is associated with diet. Our aim was to investigate the dietary patterns of a Brazilian population with this condition and compare them with the recommended diet. METHODS: A cross-sectional study was conducted on 96 non-alcoholic fatty liver disease patients before any dietetic counseling. All patients underwent abdominal ultrasound, biochemical tests, dietary evaluations, and anthropometric evaluations. Their food intake was assessed by a semi-quantitative food-frequency questionnaire and 24-hour food recall. RESULTS: The median patient age was 53 years, and 77% of the individuals were women. Most (67.7%) participants were obese, and a large waist circumference was observed in 80.2% subjects. Almost 70% of the participants had metabolic syndrome, and 62.3% presented evidence of either insulin resistance or overt diabetes. Most patients (51.5, 58.5, and 61.7%, respectively) exceeded the recommendations for energy intake, as well as total and saturated fat. All patients consumed less than the amount of recommended monounsaturated fatty acids, and 52.1 and 76.6% of them consumed less polyunsaturated fatty acids and fiber, respectively, than recommended. In most patients, the calcium, sodium, potassium, pyridoxine, and vitamin C intake did not meet the recommendations, and in 10.5-15.5% of individuals, the tolerable upper limit intake for sodium was exceeded. The patients presented a significantly high intake of meats, fats, sugars, legumes (beans), and vegetables and a low consumption of cereals, fruits, and dairy products compared with the recommendations. CONCLUSIONS: Although patients with non-alcoholic fatty liver disease exhibited high energy and lipid consumption, most of them had inadequate intake of some micronutrients. The possible role of nutrient-deficient intake in the development of non-alcoholic fatty liver disease warrants investigation.

Este estudo retrospectivo investigou os aspectos clínicos de 295 pacientes com hepatite C crônica. A idade variou entre 13 e 81 anos (mediana=49 anos) sendo 55% entre 40 a 60 anos. O fator de risco principal foi hemotransfusão, seguido pelo uso de drogas injetáveis. A maioria dos casos era assintomática. Cinqüenta por cento dos pacientes apresentavam complicações da cirrose hepática ao diagnóstico. Não houve associação entre o genótipo e a gravidade da fibrose hepática. Os fenômenos auto-imunes foram diagnosticados em 10% dos pacientes. A ALT estava aumentada em 69% dos casos. Trinta e dois por cento tinham ALT normal e 8% destes eram cirróticos. Somente 26% dos pacientes tratados com interferon mais ribavirina por 48 semanas apresentaram resposta virológica sustentada. Os resultados deste estudo alertam para a alta morbidade da hepatite C no nosso meio.
Clinical aspects of chronic hepatitis C in a retrospective study including 295 patients were studied. The age ranged from 13 to 81 years (mean = 49 years); 55% were 40 to 60 years old. The mainly risk factor to infection was blood transfusion, followed by drug injection. Most patients were asymptomatic but 50% had cirrhosis by the time of diagnosis. Genotype was not related to worse status of fibrosis. Auto-immune events appeared in 10% of patients. High and normal levels of alanine-aminotransferase (ALT) were found in 69% and 32% of the patients, respectively. Eight per cent of the patients with normal levels of ALT were cirrhotic. Only 26% of treated patients had sustained response to virus after treatment with interferon and ribavirin for 48 weeks. The results show a high morbidity.
