title: [Clinical single case study (n-of-1 trial)].
abstract: We conducted a single case (N-of-1) randomized trial in two patients. In the first case with bronchiolitis obliterans after lung transplantation a beneficial effect of inhaled steroids could be documented. The second patient suffered from symptoms compatible with HIV-associated M. Addison improving after cortisone, but the adrenocortical function was normal. Because the patient required the cortison treatment to be continued, we performed a n-of-1 trial which demonstrated the inefficacy of cortisone. This experience underscores the feasibility and usefulness of N-of-1 randomized clinical trials in medical practice.
