From 1907 patients with chronic hepatitis C proposed for treatment, we analysed 1380 (1124 naive and 256 treatment-experienced) with complete follow-up. Genotype and HCV RNA quantification were assayed by commercial tests. Viremia was considered high if >800,000IU/mL, and low if <400,000IU/mL. Liver fibrosis was staged in 614 patients. RESULTS: Genotype 1 was the most frequent (60%), followed by 3 (25%), 4 (9%)...

A reactivação do vírus da hepatite B em doentes com neoplasias hematológicas é uma complicação frequente da quimioterapia ou da terapêutica imunomoduladora. Os autores descrevem o caso dum doente com linfoma não-Hodgkin e história de infecção passada pelo VHB que desenvolveu hepatite fulminante após quimioterapia. Os mecanismos de reactivação do VHB são discutidos e as recomendações sobre profilaxia são apresen...
A determinação dos níveis séricos de transferrina deficiente em carbo-hidratos (CDT) e do rácio de transferrina no consumidor abusivo persistente de álcool aparece com promissora utilidade na área da alcoologia. Na série actual demonstra-se excelente especificidade (970 o) no entanto com fraca sensibilidade (52° o) para o CDT. Contudo o rácio CDT Tft adiciona-lhe uma sensibilidade acrescida atingindo 740 o mant...
The determination of serum levels of carbohydrate deficient transferrin (CDT) and transferrin ratio in the persistent abusive alcohol consumer arises with promising utility in the study of alcohol related disorders. This series shows the excellent specificity (97%), though poor sensitivity (52%), for CDT. However the CDT/Tft ratio affords a higher sensitivity, reaching 74%, maintaining the high specificity. In ...
