Methods: One-hundred-and-two patients with NAFLD diagnosed in the period 1994-2001 were identified. Eighty were broug ht in for new investigations, including LFTs, blood pressure, BMI, lipid profile , blood glucose and insulin. Original liver biopsy was re-evaluated. Results: S ixty-two patients (77%) were males (median age 46 years; mean follow-up time 2.8 ±1.2 years). Fifty-four patients (68%) were light to moderately overweigh t with body mass index (BMI) 25-30 kg/m 2. Mean BMI (28.2) was the same at diag nosis and at follow-up (28.3). At the new examination, 18 patients (23%) had d eveloped diabetes mellitus type II (n = 6) or had impaired fasting glucose (IFG) (n = 12), compared to only 2 patients at diagnosis. Hyperinsulinemia was observ ed in 19 patients (24%). Dyslipidemia, with elevated triglycerides and/or hyper cholesterolemia, was now present in 65 patients (81%). Twenty-two patients (27 %) had hypertension compared to 9 (11%) at diagnosis. Liver biopsy was perform ed in 24%, and 89%of those fulfilled the criteria for NAFLD. However,mild infl ammation and fibrosis was observed, grade 1-2 (n = 17), stage I-II (n = 13) an d none had cirrhosis. Conclusion: A significant proportion of patients with both clinical and histological diagnosis of NAFLD develop metabolic problems soon af ter diagnosis. These patients should be screened regularly for metabolic disorde rs.展开更多
