Abstract: To examine the prevalence and prognostic implications of low serum testosterone levels in men with chronic liver disease.We conducted an observational study at a tertiary referral centre.Baseline serum testosterone was measured in 171 men presenting to the Victorian Liver Transplant Unit for liver transplant evaluation. Patients were followed up to liver transplant or death.Sixty-one per cent of men had a low total testosterone level (TT, <10 nm), and 90% of men had a low calculated free testosterone level (cFT, <230 pm). During the available observation time (median 8 months, interquartile range 4-14 months), 56 men (33%) died and 63 (37%) received a liver transplant. Fifty-two (30%) survived without a transplant. Median time to death was 8 months (range 2-13) and to liver transplant was 8 months (4-14). Baseline low TT and cFT levels both (P < 0·0001) predicted mortality. Moreover, in a Cox proportional hazard model, both low total (P = 0·02) and free testosterone (P = 0·007) levels remained predictive of death independently of established prognostic factors, such as the model for end-stage liver disease (MELD) score and serum sodium levels. A decrease in TT by 1 nm and in cFT by 10 pm was associated with an 8% increase in mortality.Low testosterone levels are common in men with severe liver disease and predict mortality independent of MELD, the standard score used to prioritize the allocation of liver transplants.
