Clinical, laboratory and ultrasonographic correlates of prostate calcifications in patients with chronic prostatitis/chronic pelvic pain syndrome.

ABSTRACT

Introduction: The research aim was to determine the role of clinical, laboratory, immunological and sonographic parameters in the development of an assessment tool for the symptomatic manifestations of prostate calcifications in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Material and methods: All men underwent a transabdominal ultrasonographic examination using a grayscale B-mode and color Doppler mapping, the evaluation of the National Institutes of Health-Chronic Prostatitis Symptom Index and the Patient Health Questionnaire-9, spermogram. Vascular endothelial growth factor (VEGF), serotonin and gamma-aminobutyrate (GABA), interleukins 1ß and 10 were determined in blood serum and ejaculate. Results: This study included 102 men aged 18-45 years. Group 1 (n = 34) consisted of patients with CP/CPPS. Group 2 included patients (n = 34) with asymptomatic prostatitis. Group 3 consisted of healthy volunteers (n = 34). More severe symptoms of prostatitis and depression, as well as frequent exacerbations in patients with CP/CPPS, were associated with ultrasound evidence of prostate calcifications, and especially the twinkling artifact (Spearman's r = 0.481; р <0.001; Spearman's r = 0.437; р <0.001, respectively).The presence of prostate calcifications in both CP/CPPS and asymptomatic prostatitis was accompanied by a significantly higher concentration of pro-inflammatory cytokine IL-1ß and a lower concentration of anti-inflammatory cytokine IL-10 in the ejaculate (p < 0.05 in both cases, Kolmogorov-Smirnov test). The clinical manifestations observed in patients with CP/CPPS and asymptomatic prostatitis were not correlated with the leukocyte count in the ejaculate or the levels of VEGF, GABA, and serotonin in both blood and ejaculate. Conclusions: Twinkling artifact potentially could serve as a valuable tool for evaluating the condition of patients with CP/CPPS and prostate calcifications.
