Abstract

Aim: We evaluated the etiology and risk factors for transient and persistently elevated aspartate and/or alanine aminotransferase levels in virus-free blood donors. Methods: Inclusion criteria: HBsAg/HBV-DNA and anti-HCV/HCV-RNA negative blood donors with elevated aspartate aminotransferase and/or alanine aminotransferase, observed in 5 blood transfusion centres in Italy from 2004 to 2005. Aspartate aminotransferase/alanine aminotransferase levels were measured at entry and every 2 months during a period of 6 months. Results: 291 individuals were evaluated (144 with persistent and 147 with transient abnormal aminotransferases). High body mass index was the most frequent (75.5%) etiological factor and was more common in the persistent elevated levels group, compared to the transient elevated levels group (82.0% vs 65.3%; p2 units/day) was reported in 23.6%, with no differences between the two groups. Instead, recent use of medication or paint exposure were most frequently associated with transient elevated levels than persistent elevated levels (61.6% vs 23.3% for drugs and 13.7% vs 4.3% for paint, p29.9). Conclusions: In virus-free blood donors, excessive body mass index is the most frequent etiological factor of abnormal aminotransferases and it is the sole risk factor associated with persistently elevated aminotransferases.
