Low glomerular filtration rate is a risk factor for ribavirin-associated anaemia in old patients with chronic hepatitis C.

Elderly patients with chronic hepatitis C have a reduced responsiveness to antiviral therapy with Peg-interferon and ribavirin. The dose reduction or the discontinuation of ribavirin due to the occurrence of anaemia is one of the most important causes for the low sustained viral response observed in older patients. We aimed to evaluate the relationship between baseline renal function and the early onset of ribavirin-associated anaemia in older (≥60 years) patients. Using data from 348 patients with chronic hepatitis C consecutively treated with peg-interferon plus ribavirin, we investigated which factors were associated with the occurrence of anaemia in elderly patients (≥60 years). Ribavirin-induced anaemia occurred in 40.5% of patients. Older patients showed a rate of anaemia significantly higher than younger patients (51.5% vs 36.3%; P = 0.009). Consequently, the rate of ribavirin dose reduction or discontinuation due to anaemia was 35.1% in older patients and 23.5% in younger patients (P = 0.029). A significantly higher proportion of older patients had a low baseline glomerular filtration rate (GFR) compared with younger patients (56.7% vs 27.1%; P < 0.001). At the multivariate regression analysis, low baseline GFR (<70 mL/min) was associated with an increased risk of ribavirin-associated anaemia only in the older patients (OR: 3.526; 95% CI: 1.385-8.979; P = 0.008). In this subset, baseline GFR was significantly correlated with both absolute (r = -0.320; P < 0.001) and relative (r = -0.324; P < 0.001) haemoglobin decrease within the first 8 weeks of treatment. In patients aged >60 years, a low pre-treatment GFR was strongly associated with the risk to develop ribavirin-related anaemia with consequent reduction in ribavirin doses.

Complete response in 5 out of 38 patients with advanced hepatocellular carcinoma treated with stem cell differentiation stage factors: case reports from a single centre.

Hepatocellular carcinoma (HCC) represents the third cause of cancer-related death. Because HCC is multi-centric with time, excluding the few transplanted patients, sooner or later it becomes untreatable with loco-regional therapies and, until some years ago, it was not responsive to systemic therapies. In 2005 a randomized trial indicated the efficacy of a product containing stem cell differentiation stage factors (SCDSF) taken from zebra fish embryos during the stage in which the totipotent stem cells are differentiating into the pluripotent adult stem cells. In such a trial the patients, with "intermediate" and "advanced" HCC according to BCLC/AASLD guidelines, presented benefit in terms of performance status (PS) and objective tumoral response, with some cases (2.4%) of complete response (CR). The aim of this cohort study is to report the experience of a tertiary referral center on the evidence of cases of CR in patients with "advanced" stage HCC treated with SCDSF as supportive care. CR was regarded as sustained disappearance of the neoplastic areas or blood supply therein, accompanied by normalization of AFP levels. Out of 49 patients consecutively recruited and retrospectively evaluated, 38 had "advanced" stage and 11 "terminal" stage. In 5 patients with "advanced" stage a sustained CR was reported (13.1%). Improvement on PS was obtained in 17 patients (34.6%). No side effects occurred. SCDSF treatment confirmed its efficacy in patients with "advanced" HCC, in terms of PS and tumoral response.
