Liver changes in Wilson's disease: the full spectrum. A report of 127 biopsies from 43 patients.

Objective: Wilson's Disease (WD) is an autosomal recessive copper overload. Several mutations of the copper pump named ATP7B have been involved. WD is difficult to diagnose mainly because of its heterogeneity of presentation.

HCV transmission in family members of subjects with HCV related chronic liver disease.

To investigate the risk of sexual and intrafamilial transmission of HCV, 220 family members of 76 patients (index cases) with chronic type C viral liver disease were tested for serological markers of HCV. Of the family members, 129 were offspring, 64 sexual partners, 15 parents and 12 siblings of the index cases. Anti-HCV was tested in all the household contacts; HCV-RNA was tested in antibody positive samples.

Scanning electron microscopy of chronic hepatitis C. An OsO4 maceration study on human biopsies.

A study at the scanning electron microscope (SEM) on the liver changes in chronic hepatitis C was carried out in human needle biopsies from four patients. Intracellular structures were visualized by a novel modification of the OsO4 maceration method that allows to investigate human pathological specimens. At low magnification we observed both sinusoidal and hepatic cells alterations: sinusoids appeared occluded by lymphocytes, hypertrophic Kupffer cells, activated perisinusoidal cells, necrotic material and apoptotic bodies.

[Hypothalamo-pituitary-adrenal function in liver cirrhosis of viral etiology].

With the aim of evaluating the glucocorticoid function and the role of the adrenal gland in hypogonadism and feminization of cirrhotic patients, we examined 11 patients with virus-induced liver cirrhosis and 8 normal subjects as controls. In each subject serum levels of cortisol (C), progesterone (P), dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulphate (DHEAS), delta 4-androstenedione (A), estrone (E1), testosterone (T), luteinizing hormone (LH) were assayed in basal conditions and after adrenocorticotropic hormone (ACTH) stimulation. Serum levels of ACTH, C, E1, estradiol (E2), T were assayed in basal condition and after dexamethasone suppression test.

Idiopathic adulthood ductopenia presenting with chronic recurrent cholestasis. A case report.

The paucity of the intrahepatic bile ducts, also known as ductopenia, is a well recognized disorder in pediatric patients. Recently, however, a similar disorder has been reported in adults and termed idiopathic adulthood ductopenia (IAD). We describe a 30-year-old patient with a 15 year history of episodes of jaundice.
