Ribavirin in hepatitis C related cryoglobulinemia.

OBJECTIVE: An open, uncontrolled trial of ribavirin, an oral guanosine nucleoside analog for treatment of hepatitis C, in patients with hepatitis C virus (HCV) associated cryoglobulinemia intolerant to interferon. METHODS: Five patients with cryoglobulinemia related to HCV infection unresponsive to interferon therapy received oral ribavirin (100 to 1200 mg daily) for 10 to 36 months. RESULTS: Patients treated with ribavirin had prompt decrease in serum aminotransferase levels and marked improvement of manifestations of cryoglobulinemia within a few weeks. Ribavirin did not eradicate HCV RNA from the sera, but a decrease in viral load was observed in 3 patients, from 232 to 86 x 10(5) copies HCV/ml. Relapse occurred within 3 months once therapy was discontinued. The drug was well tolerated, but mild dose related hemolysis was common. CONCLUSION: Ribavirin monotherapy may be effective in patients with symptomatic cryoglobulinemia related to HCV infection, but this effect is not sustained when ribavirin therapy is discontinued.

Gas chromatographic-mass spectrometric method to characterise the transfer of dietary odorous compounds into plasma and milk.

The flavours contained in a mammalian mother's milk can exert a marked influence on her offspring's proximate suckling behaviour and later preferences. The aim of this study was to establish a reliable analytical procedure to characterise the mammary transfer of selected volatile constituents of maternal food from non-pregnant and recently parturient ewes. Six known volatile compounds, most representative of cumin aroma (alpha-pinene, gamma-terpinene, cuminaldehyde, p-cymene, limonene and cineole), were traced in the blood and milk of ewes fed with cumin seeds, using liquid-liquid extraction combined with gas chromatography-specific ion monitoring mass spectrometry. Among the six cumin odour markers, only one, p-cymene, was transferred in quantifiable amounts into the venous plasma. The other cumin markers could only be detected as traces corresponding to amounts lower that the limit of quantification. In milk, four of the cumin markers could be detected, and two of these were quantified.
