Strong correlation by ultrasonography of hepatomegaly and the presence of co-infection in HIV/HCV cirrhotic patients

OBJECTIVES: Progression of hepatic fibrosis is accelerated in patients co-infected with human immunodeficiency virus and hepatitis C virus compared to hepatitis C virus mono-infected patients. This study aimed to compare ultrasound features and selected clinical and biochemical variables between patients with human immunodeficiency virus/hepatitis C virus co-infection (n = 16) versus hepatitis C virus mono-infection (n = 16). METHODS: Each patient underwent abdominal ultrasound, and a specific evaluation was performed in order to detect findings consistent with chronic liver disease. Characterization of spleen size, liver structural pattern, diameter of the portal, spleen, and mesenteric veins was based on classical ultrasound parameters. Propensity score was used for control of selection bias and performed using binary logistic regression to generate a score for each patient. The Fisher and Mann-Whitney tests were used to evaluate categorical variables and continuous variables, respectively. RESULTS: On univariate analysis right hepatic lobe size was larger in human immunodeficiency virus/hepatitis C virus patients (157.06 ± 17.56 mm) compared to hepatitis C virus mono-infected patients (134.94 ± 16.95 mm) (p = 0.0011). The left hepatic lobe was also significantly larger in human immunodeficiency virus/hepatitis C virus patients Cirrhosis (115.88 ±22.69 mm) versus hepatitis C virus mono-infected patients (95.06 ±24.18 mm) (p= 0.0177). Also, there was a strong correlation between hepatomegaly and co-infection (p=0.005). CONCLUSION: Human immunodeficiency virus infection was the primary variable influencing liver enlargement in this population. Hepatomegaly on ultrasound was more common among cirrhotic human immunodeficiency virus/hepatitis C virus co-infected patients than among cirrhotic hepatitis C virus mono-infected patients. This aspect is very important in the management of human immunodeficiency virus/hepatitis C virus co-infected patients, because screening for hepatocellular carcinoma is necessary in this population.

Correlations between biochemical findings and nonalcoholic fatty liver disease (NAFLD) in morbidly obese patients

Controversies about frequency, diagnosis and possibility of progression toward chronic disease of fatty degeneration of the liver in morbidly obese patients exist. Aim - To make an analysis considering the frequency and correlation of NAFLD with bariatric operations / Existem controvérsias sobre a frequência, diagnóstico e possibilidade de progressão para doença crônica da degeneração gordurosa do fígado em portadores de obesidade. Objetivo - analisar a frequência e correlação da NAFD com a cirurgia bariátrica. Pacientes e método - análise retrospectiva em 60 pacientes candidatos à cirurgia bariátrica com indicação de gastroplastia com derivação intestinal em Y de Roux...
