Granulocyte elastase as a sensitive diagnostic parameter of silent male genital tract inflammation.
Elastase, a specific inflammatory parameter of polymorphonuclear (PMN) granulocytes, was quantified with a sensitive enzyme immunoassay in the ejaculates of 188 patients consulting the andrological outpatient service. Correlations of the elastase concentrations to other parameters used up to now for the diagnosis of silent male genital tract inflammation were statistically evaluated by the CHI2-test. A correlation was found neither to the percentage of morphologically intact spermatozoa in the differential spermiocytogram and the total number of spermatozoa nor to the pH-value and viscosity of the ejaculate. However, release of elastase into the ejaculates was clearly associated with the occurrence of bacteria in native and stained smears or with the numbers of round cells present. Moreover, leukocyte counts in stained smears as well as an inflammation coefficient were highly significantly correlated to elastase concentrations. Obviously, quantification of granulocyte elastase in seminal plasma enables a rapid diagnosis of silent male genital tract inflammation, since even a single determination gives a reliable criterion and sequential determinations may allow the control of the course of the disease during therapy.
