Mucosal Candida infection and colonisation as well as associated risk factors in solid organ transplant recipients.

More detailed information on Candida colonisation and infection of the mucous membranes in organ transplant recipients (OTR) is of particular interest. Therefore, this issue was prospectively evaluated in 400 different OTR in different posttransplantation periods as well as in 405 healthy age- and sex-matched controls. In addition, possible risk factors and the clinical condition in the OTR were evaluated. Independent of the transplanted organ there is a statistically significant decrease in the number of positive culture results, of symptomatic candidiasis and an increase of isolated non-albicans Candida species corresponding to length of the posttransplantation period. No significant differences could be observed in the OTR in association with different immunosuppressive regimen; however, higher dosages of corticosteroids and tacrolimus correlated with symptomatic candidiasis. As Candida spp. may also cause systemic infection and dissemination, additional knowledge about cofactors and associated strains may have an impact on therapeutic decisions.
