title: Demodex folliculorum in renal transplant patients.
abstract: BACKGROUND
  Demodex folliculorum (DF), which is a resident in human pilosebaceous follicles, has been implicated in infections of patients under cancer chemotherapy and with AIDS.
  
  
  OBJECTIVE
  We aimed to determine the influence of immunosuppression on carriage of DF.
  
  
  METHODS
  Mite density was compared, of 30 renal transplant (RT) patients under a combination therapy of cyclosporine, azathioprine and prednisolone with that of age- and sex-matched controls. Two samples of standardized skin surface biopsies were taken from each subject.
  
  
  RESULTS
  DF was not found in any of the RT patients while a mean density of 0.55 DF/cm2 was present in healthy subjects (Fisher's exact test, p < 0.0001). The relationship between mite density and classic risk factors was not found to be statistically significant (Fisher's exact test, p > 0.05).
  
  
  CONCLUSIONS
  Our findings indicate that there may be other factors than immunosuppressive therapy influencing DF density.
