RESUMO
BACKGROUND: Obesity is a multifactorial disease characterized by fat accumulation, usually associated with non-alcoholic fatty liver disease, which can lead to advanced fibrosis or even cirrhosis. Bariatric surgery (BS) is a treatment approved for weight loss in morbidly obese patients. However, complications from this modality of treatment have been reported and liver cirrhosis connotes more risk procedure. AIMS: Evaluate non-invasive methods transient elastography (THE) and scores to establish the degree of liver fibrosis in patients submitted to BS, comparing their performance with liver histology. METHODS: We calculated liver fibrosis by non-invasive scores AST to platelet ration index (APRI), fibrosis-4 (FIB-4) and non-alcoholic fatty liver disease (NAFLD) score and THE before and 6 months after the bariatric surgery. The results were compared to liver histology. RESULTS: We included 85 patients, 69.4% females, with a mean age of 36 years, with a mean body mass index (BMI) of 41 kg/m2. The non-invasive scores were able to exclude clinically significant fibrosis in 85.9% (APRI) and advanced fibrosis in 96.5% (FIB-4) and 51.8% (NAFLD score). When comparing with the histological findings, the correlation with elastography was 45.9% for the same degree of fibrosis, with high negative predictive value (94.4%) in pre-surgical analysis. In the post-surgical analysis, the correlation with histology was 69.4% for THE and the negative predictive value to exclude clinically significant fibrosis was 98.5%. CONCLUSION: THE showed low correlation with histology in the pre-surgical analysis. All the methods had better results in post bariatric evaluation comparing with pre-bariatric data and the non-invasive FIB-4 score showed the best of them.

Gaucher's disease and alpha-1 antitrypsin deficiency are genetic diseases that can cause different kinds of liver damage, but are rarely associated with cirrhosis. Here, we describe the case of a patient with both diseases who presented with cirrhosis, followed by liver failure and death. Although the interaction between these two diseases remains unclear, we suspect the involvement of an epigenetic factor in the evolution of the aggressive liver disease.

Amiloidose cardíaca é causada por um depósito amiloide entre as fibras cardíacas que pode levar a distúrbio de condução, cardiomiopatia restritiva, baixo débito e comprometimento atrial isolado. Relata-se caso de paciente feminina, 66 anos que há três anos iniciou com perda de peso significativa (40,4 kg)evoluindo com edema de membros inferiores. Na investigação observou-se aumento cardíaco global, e o ecocardiograma evidenciou cardiopatia restritiva infiltrativa e derrame pericárdico. Pela alta suspeição clínica, solicitou-se ressonância magnética cardíaca que foi altamente sugestiva de amiloidose cardíaca.O diagnóstico definitivo se confirma pela biopsia endomiocárdica, porém a ressonância cardíaca é descrita como bom método diagnóstico com raros resultados falso-positivos.
Cardiac amyloidosis is caused by amyloid deposits in cardiac fibers that can lead to conduction disturbance, restrictive cardiomyopathy, low output and isolated atrial involvement. This case report described a female patient, 66 years old, with significant weight loss (40.4kg) that began three year sago, progressing to lower limb edema. On investigation, overall cardiac enlargement was noted,with the echocardiogram showing infiltrative restrictive cardiomyopathy and pericardial effusion. High clinical suspicions prompted a request for a cardiac MRI that strongly suggested cardiacamyloidosis. Although definitive diagnoses require endomyocardial biopsies, cardiac MRI is described as a good diagnostic method with rare false-positive results.
