Nonalcoholic fatty liver disease in patients with coronary disease from a Brazil northeast area.

Background Nonalcoholic fatty liver disease (NAFLD) is the most frequent chronic liver injury around the world. It is associated with metabolic syndrome and cardiovascular diseases. Objective To evaluate the frequency and relevance of NAFLD in patients with coronary artery disease (CAD). Methods Patients from a Brazil Northeast area, who underwent elective coronary angiography (CAG) from 2009 to 2010 were included. All of them had suspicion of CAD. Criteria to CAD: presence of obstructive lesions in the epicardial coronary arteries, or in their major branches. NAFLD criteria: presence of hepatic steatosis on ultrasound; exclusion of other liver diseases; ethanol intake ≤ 20g/day. Statistics analysis included Independent t-test, Mann-Whitney and Pearson's chi-squared test. Multivariate regression analysis measured the relationship between the risk factors and the concomitant presence of CAD and NAFLD. Results A total of 244 patients were evaluated: 63.5% had CAD and 42.2% had NAFLD. NAFLD was observed in 43.9% of the CAD patients. The regression analysis showed that the relationship between CAD and NAFLD was positively correlated with HOMA-IR ≥3.0 or insulin resistance and overweight/obesity. Conclusion NAFLD was frequent among CAD patients; insulin resistance and overweight/obesity were the most relevant risk factors related to the association NAFLD and CAD. The results suggest that patients with CAD should be evaluated for NAFLD.

Contexto Doença hepática gordurosa não alcoólica (DHGNA) é uma das mais frequentes hepatopatias crônicas da atualidade. Associa-se à síndrome metabólica e doenças cardiovasculares. Objetivo Avaliar a frequência e relevância da DHGNA em pacientes com doença arterial coronariana (DAC). Métodos Foram avaliados pacientes de uma área do Nordeste de Brasil, submetidos à angiografia coronariana, com suspeita de DAC, entre 2009-2010. Critérios para DAC: presença de lesões obstrutivas em artérias coronárias epicárdicas ou seus principais ramos. Critérios para DHGNA: esteatose hepática na ultrassonografia; exclusão de outras doenças hepáticas; ingestão de etanol ≤20g/dia. Análise estatística incluiu os testes t, Mann-Whitney e qui-quadrado de Pearson. Análise de regressão multivariada mediu a força da correlação entre fatores de risco e concomitância de DAC e DHGNA. Resultados Foram avaliados 244 pacientes submetidos à angiografia coronariana: 63,5% apresentavam DAC e 42,2% DHGNA. DHGNA foi observada em 43,9% dos doentes com DAC. A análise de regressão mostrou que a possibilidade de ocorrência concomitante de DAC e DHGNA foi positivamente correlacionadas à resistência a insulina e ao sobrepeso/obesidade. Conclusão DHGNA foi frequente entre os pacientes com DAC; resistência à insulina e sobrepeso/obesidade foram os mais relevantes fatores de risco relacionados à associação DHGNA e DAC. Os dados sugerem que pacientes com DAC devem ser avaliados para DHGNA. .

Nonalcoholic fatty liver disease in menopausal women.

CONTEXT: Nonalcoholic Fatty Liver Disease (NAFLD) is common in postmenopausal women. It is associated with metabolic syndrome. However, the influence of hormone replacement therapy in NAFLD development in these women needs to be investigated. This study aimed to describe the clinical characteristics of NAFLD in postmenopausal women, and the relationship between hormone replacement therapy and this disease. METHODS: From April 2009 to April 2011, 292 postmenopausal women from National Health System from Northeast of Brazil were selected, and 251 were included in this study. Menopause was defined as the absence of menstruation for 12 consecutive months in otherwise healthy women. Criteria to NAFLD included: presence of steatosis on abdominal ultrasound; history of alcohol consumption less than 20 g/day and exclusion of other liver diseases. All women underwent a clinical evaluation. Standard univariate and multivariate analyses were performed to evaluate the results. RESULTS: The mean age was 56.5 ± 6.7 years. Hormone replacement therapy was referred by 21.1% (53) women and 78.9% (198) was not. Prevalence of NAFLD was 37.1% (93/251) in postmenopausal women, 26,4% (14/53) in the group with hormone replacement therapy and 39,9% (79/198) without hormone replacement therapy. Gamma-glutamyl transpeptidase (P = 0.001), alanine transaminase (P<0.01), ferritin (P<0.001) and insulin resistance (homeostatic model assessment of insulin resistance ≥3) (P<0.001) were higher in the group of women with NAFLD diagnosis who did not referred the use of hormone replacement therapy. Metabolic syndrome was also more frequent in women with NAFLD, who did not refer hormone replacement therapy. CONCLUSION: In conclusion this data suggests elevated prevalence of NAFLD in postmenopausal women; negative association of hormone replacement therapy and NAFLD.
