RESUMO
BACKGROUND: Diabetes is frequently diagnosed in patients with cirrhosis and represents an important risk factor for morbidity and mortality. Pharmacological therapy is limited due to hepatotoxicity and the risk of hypoglycemia. Investigations on medical practice in this patient population, frequency of diabetes-associated complications and the impact of quality of metabolic control are rare. AIMS AND METHODS: A retrospective analysis was performed to compare the effects of hypoglycemic treatment, the achieved glycemic control under therapy, the prevalence of typical cirrhosis-related or microangiopathic complications, and cardiovascular comorbidities between a group of diabetic patients with cirrhosis (n = 87) and a nondiabetic cirrhotic population (n = 198). RESULTS: The prevalence of diabetes in our cohort was 30.5%. Of all diabetic patients, 39.1% received therapy which might potentially result in serious side effects in patients with end-stage liver disease. The rate of ongoing alcohol abuse (28.7%) and noncompliance under medication (41.4%) was high. Only 28.7% of all diabetic subjects showed satisfactory (as defined by HbA1c ≤ 6.5%) glycemic control under therapy. Patients achieving satisfactory control experienced a lower rate of certain cirrhosis-related complications such as hepatic encephalopathy (HE) and hepatocellular carcinoma (HCC), arterial hypertension, and hypercholesterolemia. HE was significantly more frequent in diabetic than nondiabetic cirrhotic patients.

Uip to 20% of patients with liver cirrhosis develop hepatogenous diabetesdue to the hepatocellular functional loss and insulin resistance. Optimizing diabetic metabolic conditions is not only important to avoid typical late complications of diabetes, but also cirrhosis-associated complications e.g. gastrointestinal bleeding, hepatic encephalopathy or the occurence of hepatocellular carcinoma. So far there have beenno recommendations orguidelines for the diagnosis and treatmentof hepatogenous diabetes. The medical teatment of a diabetic condition is mainly influenced by its side effects. The risk of hypoglycemia must be considered carefully during drug treatment, especially in patients with chronic alcohol abuse. Suitable oral antidiabetics are glinides and short-acting sulfonylureas or possibly meal-related insulin administration with short-acting insulins or rapid-acting insulin analogues. Biguanide and PPAR-gamma agonists are contraindicated because of side effects in liver cirrhosis. Regarding basic treatment, an adequate daily energy and protein supply should be ensuredbecause the majority of patients with liver cirrhosis are malnourished.

Medical treatment of patients with liver cirrhosis consists mainly of symptomatic therapy of associated complications. Apart from the classical complications of cirrhosis, e. g. ascites, portal hypertension or hepatic encephalopathy, other frequent complications are neglected in everyday medicine. The incidence of metabolic disturbances seems to be similar to the prevalence of classical complications of liver cirrhosis, such as portal hypertension or ascites. Osteoporosis is an important manifestation of hepatic osteopathy, especially in chronic cholestatic diseases and in candidates for liver transplantation, which necessitates timely adequate diagnostic test (e. g. osteodensitometry) and treatment (pre-emptive and causal). Malnutrition, especially when related to protein- and energy supply, is very common in patients with liver cirrhosis and has prognostic significance regarding mortality and complication rates. A sufficient daily energy and protein supply should be ensured, one which is higher than that for the normal population. Additional substitution of vitamins and trace elements is indicated when symptoms of deficiency became apparent.
