[Immunologic studies for the diagnosis of chronic prostatitis].

A prospective study comparing the results of Antibody-Coating-Test (ABC) in semen and aspiration biopsy of the prostate with immunodiffusion of the former was carried out. In 143 patients with clinical signs of prostatitis only 98 showed a positive ABC in their ejaculates. IGA-specific ABC was positive in 75%, IGG-specific ABC in 48%, and IGM-specific ABC in 9.6% respectively. Specimens gained by aspiration biopsy of the prostate were also demonstrating positive ABC. Consistently negative was the ABC in 15 healthy male who served as a control. In 30 patients the ABC-Test of ejaculate speciments was compared with complement (C3) and coeruloplasmin content of the ejaculates using immunodiffusion technique. Contrary to the reports in the literature, however, elevated levels of complement (C3) and coeruloplasmin were not correlated with local infection of the prostate proven by ABC.
