A 74-year-old housewife was admitted to the hospital with complaints of high fever and general fatigue. The physical examinations on admission showed no particular findings except for mild hepatomegaly, but laboratory findings showed severe liver dysfunction, active inflammation and negative tuberculine test. On the 4th day, she suddenly complained of severe respiratory distress. A chest X-ray film demonstrated surprising changes in comparison with that taken on admission. On suspicion of adult respiratory distress syndrome (ARDS) associated with military tuberculosis (Miliary TB), administration of Methylpredonisolone (1000 mg a day for 3 days) in addition to antituberculous drugs was immediately started. With this therapy she was recovered from such ill condition, but the general exhaustion and slight fever continued. We suspected that her condition might be due to adrenocortical involvement of Miliary TB and hormonal examinations were performed. Unexpectedly, Cushing's syndrome was suspected on the basis of the following; high level of plasma cortisol without normal daily variation, normal ACTH level, an absent response to the Dexamethasone suppression test. Computed tomography revealed left side adrenal mass. During these examinations, renal dysfunction probably due to Miliary TB grew gradually worse and she died of renal failure on the 56th day. Necropsy revealed disseminated tuberculosis involving the lungs and the liver, but the adrenal glands were not examined.

Abnormal liver tests, right upper quadrant pain and hepatomegaly occurring in an obese or in a diabetic patient may point to the presence of fat or of glycogen accumulation in the liver parenchymal cells. Marked hepatomegaly due to cytoplasmic glycogen deposition is mainly found in poorly controlled insulin-dependent diabetic patients. If accompanied by cushingoid features, growth retardation and by delayed puberty, a diagnosis of Mauriac syndrome can be made. Hyperglycaemia, insulin administration and increased concentrations of the counterregulatory hormone cortisol may all play a role in the glycogen deposition by their concerted actions on the glycogen phosphorylase and synthase enzymes, promoting the accumulation of glycogen. Hypercortisolism may be responsible for growth retardation and delayed puberty in Mauriac patients. Regression of hepatomegaly and of the associated clinical characteristics may be obtained by a better metabolic control due to the administration of long-acting insulin and the change from single to twice daily injections. Fatty liver is rare in insulin-dependent diabetic patients and is indicative of a poor diabetic control. This process is quickly reversible by adequate insulin treatment. Steatosis is frequently found in maturity-onset diabetics and in obese patients. The pathogenetic mechanisms leading to the accumulation of triglycerides and of fatty acids in the hepatocytes can easily be understood from the normal cycling of fatty acids between the adiopose tissue and the liver. Histologic features of nonalcoholic steatohepatitis can also be found in obese and in diabetic patients. Steatohepatitis may rarely evolve into cirrhosis. In general, there is no correlation between the degree of the biochemical alterations and the severity of the histological findings.(ABSTRACT TRUNCATED AT 250 WORDS)

Patients with type 1 diabetes and poor metabolic control can develop hepatomegaly due to intrahepatic glycogen deposition. If these patients also have elevated liver enzymes, dyslipidemia, cushingoid features and delayed growth or sexual maturation, Mauriac syndrome can be diagnosed. This disorder is common and reversible with optimization of insulin therapy. We report three adolescents with type 1 diabetes and a long-standing history of poor glycemic control, who developed hepatomegaly, elevated liver enzymes and dyslipidemia with preserved liver function. One of these patients also had delayed growth and another had hypogonadotropic hypogonadism. Liver ultrasound showed changes suggestive of glycogenosis. In all three patients, optimization of insulin therapy achieved good glycemic control and reversed the manifestations within 2 weeks. The etiology of Mauriac syndrome is controversial since both prolonged hyperglycemia and hyperinsulinization produce glycogen accumulation in the liver. Hypercortisolism (due to ketosis or hypoglycemia) contributes to glycogen storage and also causes growth and sexual maturation delay.
