Background:
Primary biliary cirrhosis (PBC) is a chronic cholestatic disease, which can progress to hepatic failure.
Aim:
To study the clinical presentation, pathological features, treatment and outcome of a group of patients with PBC.
Material And Methods:
Retrospective review of medical records of 115 patients (110 females, age range 30-76 years) with PBC. Clinical presentation, pathological stage, treatment, outcome and eventual use of liver transplantation, were recorded.
Result:
Seventy eight percent of patients were symptomatic at presentation (itching in 69% and malaise in 62%). Antimitochondrial antibodies were positive in 56%. No clinical or laboratory differences were observed between symptomatic patients or those with positive antimitochondrial antibodies and the rest of the study group. Sjögren syndrome was present in 38%, hypothyroidism in 13%, scleroderma in 7% and rheumatoid arthritis in 5%. Initially, 61% had fibrosis and/or cirrhosis, and ursodeoxycholic acid was indicated in 94% of the patients. Fifteen patients underwent liver transplantation due to upper digestive bleeding or itching. Survival has been 67% at 36 months after transplantation. In one transplanted liver, PBC recurred.
Conclusions:
An early diagnosis and treatment of a progressive disease such as PBC will reduce the incidence of complications and the use of costly treatments.

Crossover Experiments
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
