Abstract

Background:: Obesity is an epidemic and chronic disease that can bring other comorbidities to the patient. Non-alcoholic fatty liver disease is present in up to 90% of these patients and can progress to hepatitis and hepatocarcinoma. The relationship of this liver disease and obesity is already well known; however, it is possible that some parameters of the comorbidities are more related than others in the pathophysiology of the disease. Aim:: Was analyzed the relationship between non-alcoholic fatty liver disease (NAFLD) and the comorbidities of metabolic syndrome in morbidly obese patients. Methods:: Was involved ultrasonography and laboratory assessment of obese patients before bariatric surgery. NAFLD was assessed using the same sonography parameters for all patients. Based on the results, the patients were divided into groups with and without NAFLD. Comparisons between them involved clinical and laboratory variables such as fasting blood glucose, insulin, HOMA-IR (homeostasis model assessment - insulin resistance), glycated hemoglobin, total cholesterol and fractions, triglycerides, alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, C-reactive protein, albumin and ferritin. Patients who reported alcohol abuse (defined as the consumption of >14 drinks per week) or who had hepatitis were excluded. Results:: Eighty-two patients (74 women and 8 men) were studied, of whom 53 (64.6%) had NAFLD and 29 (35.4%) did not. The levels of glycated hemoglobin (p=0.05) and LDL cholesterol (p=0.01) were significantly altered in patients with NAFLD. However, weight, body mass index and excess weight did not differ significantly between the groups (p=0.835, p=0.488 and p=0.727, respectively). Conclusions:: Altered LDL cholesterol and glycated hemoglobin levels were related to the presence of NAFLD. Racional: : A obesidade é doença epidêmica e crônica que pode trazer outras comorbidades ao paciente. A doença hepática gordurosa não alcoólica está presente em até 90% desses pacientes e pode evoluir para hepatite e hepatocarcinoma. A relação desta hepatopatia e a obesidade já é bem conhecida; porém, é possível que alguns parâmetros das comorbidades estejam mais relacionados do que outros na fisiopatogenia da doença. Objetivo:: Correlacionar a doença hepática gordurosa não alcoólica (DHGNA) com as comorbidades da síndrome metabólica em pacientes obesos mórbidos em pré-operatório de cirurgia bariátrica. Métodos:: Avaliação ultrassonográfica e laboratorial de pacientes obesos em pré-operatório para cirurgia bariátrica. Durante o preparo para a operação em todos os pacientes foi avaliada DHGNA através de ultrassonografia. De acordo com o resultado, os pacientes foram separados em dois grupos: sem DHGNA e com DHGNA. Para análise entre os grupos, avaliaram-se as seguintes variáveis clínicas e laboratoriais: insulina, HOMA-IR, hemoglobina glicada, colesterol total e frações, triglicerídeos, transaminase pirúvica, transaminase glutâmico oxalacética, gama glutamil transferase, proteína C reativa, albumina, ferritina. Os pacientes que relataram uso de bebida alcoólica ou que apresentaram hepatite foram excluídos do estudo. Resultados:: Avaliou-se um total de 82 pacientes (74 mulheres e 8 homens), sendo 53 (64.6%) com DHGNA e 29 (35.4%) sem. Os níveis de hemoglobina glicada (p=0.05) e de LDL (p=0.01) mostraram-se mais relacionados no grupo de pacientes com DHGNA. Conclusão:: A hemoglobina glicada e o LDL tiveram relação com a presença de DHGA.
