Late side-effects of stem cell transplantation include hypogonadism with infertility and sexual dysfunction, but gynaecomastia is less well recognised. We report five cases of gynaecomastia with features of hypergonadotrophic hypogonadism (primary testicular failure), who received either a TBI/cyclophosphamide conditioned allograft (n = 3) or a BEAM autograft (n = 2). Patients receiving an allograft had gynaecomastia, Leydig cell insufficiency (LCI) diminished libido and erectile dysfunction. Surgery was required in one case, while in two cases the gynaecomastia resolved spontaneously after 6 months. Two patients also had gynaecomastia and sexual dysfunction, severe hypogonadism, very low testosterone levels and marked hyperprolactinaemia following autoBMT. Both responded well to testosterone replacement therapy (TRT). As a group, all patients had primary testicular failure and all except one, had LCI (compensated or frank). However, there was no correlation between the severity of gynaecomastia and the degree of endocrine dysfunction. This preliminary study is the first to suggest that gynaecomastia, due to primary hypogonadism and LCI, may be a significant complication of myeloablative conditioning therapy. Therefore gynaecomastia in BMT recipients must always be treated as a pathological entity as it may be the external manifestation of a complex endocrine pathology. It is a potentially treatable condition. Although spontaneously reversible, some patients may require TRT or even surgery. We recommend comprehensive endocrine testing in conjunction with a reproductive endocrinologist and prompt intervention to alleviate embarrassment and anxiety in afflicted BMT recipients.

The development of reduced-intensity conditioning (RIC) and the success of BMT for paediatric sickle cell disease (SCD) have raised the possibility of revisiting this prospect in adults as well. In a chronic debilitating disorder managed with supportive therapy, the patients' perception is critical in the advancement of any potential curative therapy. To explore this aspect, we undertook a questionnaire-based survey on 30 adults with SCD. Sixty two per cent of the patients were ready to accept a transplant-related mortality (TRM) >10%; 30% of them a TRM >30%. A risk of graft failure (GF) >10% was acceptable to 64%, with a risk >30% acceptable to 41%. Infertility was acceptable to only 50%. Chronic graft-versus-host disease (GVHD) was unacceptable to the majority (80%). Seventy six per cent% of patients had a full sibling and 60% were willing to participate in a clinical trial of RIC transplantation. This survey suggests that the majority of adults with SCD might be willing to consider a curative option such as RIC transplantation even with a high TRM or GF. The major concerns relate to chronic GVHD and infertility. There is an urgent need to explore RIC transplants in SCD patients within the framework of a clinical trial, considering patient perception regarding cure and complications.
