title: Immunologic findings in Peyronie's disease: a controlled study.
abstract: OBJECTIVE
  Recent literature suggests the hypothesis of an immune etiology of Peyronie's disease. In this controlled study, the immune response pattern of the disease is investigated.
  
  
  METHODS
  Sixty-six patients with Peyronie's disease and 20 age-matched controls were studied. In all patients, skin test (multitest), in vitro lymphocyte transformation test (LTT), serum immunoglobulin (Ig) A, G, and M, anti-DNA, antinuclear and anti-smooth muscle cell antibodies, C3 and C4 complement fractions, antistreptolysin, and C-reactive protein titers were evaluated.
  
  
  RESULTS
  A fair percentage (75.8%) of the patients with Peyronie's disease exhibited at least one abnormal immunologic test, in comparison to only 10% among controls (chi-square = 27.8, df = 1; P < 0.0001). Alterations of cell-mediated immunity (multitest, LTT) were observed in 48.5% of patients, alterations of humoral immunity (Ig) in 31.8%, and alterations of markers of autoimmune disorders (autoantibodies, complement activation) in 37.9% of the cases.
  
  
  CONCLUSIONS
  Our results support the hypothesis that there is some involvement of the immune system in the pathogenesis of Peyronie's disease, although the available data still appear to be insufficient to formulate a definite pathogenetic hypothesis.
