Epidemiological characteristics of 333 proven and probable invasive mould infections (IMIs) among solid organ transplant recipients (SOTRs) identified between 2004 and 2008 from the Prospective Antifungal Therapy Alliance (PATH) registry are presented. Liver transplant recipients (LTRs) had the lowest median time to IMIs (109 days; interquartile range [IQR] 24-611 days), the highest rate of disseminated disease (n/N = 18/33; 55%), and highest mortality (n/N = 21/33; 64%). Lung transplant recipients had highest median time to IMIs (486 days; IQR 117-1358 days) and lowest mortality (n/N = 31/184; 17%). Complete or partial response at week 12 in patients with invasive aspergillosis (IA) was 67% (n/N = 189/281), and 41% (n/N = 9/22) in mucormycosis patients. In the composite outcome of death or no response to therapy, LTRs had the worst outcome. Higher suspicion of mold infection and institution of appropriate antifungal prophylactic strategies are warranted, especially in high risk LTRs.
