ABSTRACT
It has been suggested that soluble CD30 (sCD30) serum levels in chronic hepatitis C are correlated with the activity of the disease and with the outcome of interferon (IFN) treatment. In this study, sCD30 serum levels in 25 patients with chronic hepatitis C, before and after treatment with IFN-2alpha, were measured. A total of 20 healthy subjects were used as controls. High sCD30 levels in serum were found in 36% of patients and in 5% of controls. In patients with sCD30 levels above or within the normal range, no significant differences in age, gender, serum transaminases and histology activity index were found. In relation to IFN treatment, only responder patients had serum sCD30 higher than controls, although the difference between responders and non-responders was not significant. No changes from baseline values were observed after treatment. Although high, sCD30 serum levels in chronic hepatitis C are not correlated with the disease activity, are not affected by IFN treatment and are not predictors of response to IFN treatment.

OBJECTIVES: Fatigue, which may have a significant impact on quality of life, is the most common reported symptom in primary biliary cirrhosis (PBC). Multiple instruments to quantify fatigue and quality of life in liver disease have been validated, but have not been broadly applied to U.S. PBC patients. This study examines the extent of fatigue and its effect on quality of life in U.S. PBC patients. METHODS: Seventy patients with PBC were administered two validated questionnaires about quality of life (the Mayo version of the NIDDK-QA) and fatigue (the Fisk Fatigue Impact Score) and a proposed physical measure of fatigue in PBC (the grip strength test) on the day of routine physician visit. Nonparametric methods were employed. RESULTS: The fatigue and quality of life domain scores (physical functioning, liver symptoms, health satisfaction, Karnofsky index) discriminated between patients with and without self-reported fatigue (p < 0.05), as opposed to the grip strength results. Fatigue and quality of life domains correlated strongly with each other (r between 0.33 and 0.74, p
