Prostatic and testicular parameters in lepromatous patients

To evaluate PSA (Prostate-specific antigen) parameters in patients with lepromatous leprosy (LL).

In a retrospective study, 23 male patients with LL were evaluated. PSA parameters (serum total PSA (tPSA), free PSA (fPSA), free-to-total PSA ratio (f/tPSA), PSA Density (PSAD)) were assessed. PSA parameters were compared with a control group.

The mean tPSA, fPSA, f/tPSA, prostate volume, and PSAD values of the patient group with LL were 1.87 +/- 0.81 ng/ml, 0.67 +/- 0.29 ng/ml, 0.36 +/- 0.11, 41.08 +/- 23.65 ml and 0.055 +/- 0.037, respectively. The mean tPSA, fPSA, f/tPSA, prostate volume, and PSAD values of the control group were 2.71 +/- 0.91 ng/ml, 0.80 +/- 0.34 ng/ml, 0.30 +/- 0.08, 65.0 +/- 28.73 ml and 0.049 +/- 0.028, respectively. The mean tPSA and prostate volume values were found to be significantly lower in the patient group with LL (p = 0.002 and 0.004, respectively). No significant difference was found between two groups in terms of mean fPSA and PSAD values (p = 0.18 and 0.5, respectively). The mean f/tPSA value was found to be significantly higher in the patient group with LL (p = 0.02). Testes in 16 (69%) patients with LL were bilaterally atrophic.

Serum tPSA values and prostate volumes in the patients with LL were significantly reduced and f/tPSA values were significantly increased. Testicular atrophy in the lepromatous cases might be due to leprosy-related orchitis and associated with a reduction in prostatic volume.
