minocycline and Pelvic-Pain

The pathogenesis of chronic prostatitis/chronic pelvic pain syndrome is unknown and factors including the host's immune response and the nervous system have been attributed to the development of CP/CPPS. We previously demonstrated that mast cells and chemokines such as CCL2 and CCL3 play an important role in mediating prostatitis. Here, we examined the role of neuroinflammation and microglia in the CNS in the development of chronic pelvic pain.. Experimental autoimmune prostatitis (EAP) was induced using a subcutaneous injection of rat prostate antigen. Sacral spinal cord tissue (segments S14-S5) was isolated and utilized for immunofluorescence or QRT-PCR analysis. Tactile allodynia was measured at baseline and at various points during EAP using Von Frey fibers as a function for pelvic pain. EAP mice were treated with minocycline after 30 days of prostatitis to test the efficacy of microglial inhibition on pelvic pain.. Prostatitis induced the expansion and activation of microglia and the development of inflammation in the spinal cord as determined by increased expression levels of CCL3, IL-1β, Iba1, and ERK1/2 phosphorylation. Microglial activation in mice with prostatitis resulted in increased expression of P2X4R and elevated levels of BDNF, two molecular markers associated with chronic pain. Pharmacological inhibition of microglia alleviated pain in mice with prostatitis and resulted in decreased expression of IL-1β, P2X4R, and BDNF.. Our data show that prostatitis leads to inflammation in the spinal cord and the activation and expansion of microglia, mechanisms that may contribute to the development and maintenance of chronic pelvic pain.

The purpose of this study was to describe our experience with ultrasound-guided aspiration of postoperative pelvic lymphocysts followed by intracavitary minocycline injection as sclerotherapy.. From 1997 to 2003, patients who developed either symptomatic or persistent lymphocyst after pelvic lymphadenectomy for gynecological malignancy were recruited in this study. All of the lymphocysts were palpable and were further examined by ultrasonography. Percutaneous ultrasound-guided needle aspiration of the lymphocyst was performed and then immediately followed by a single-dose injection of minocycline into the collapsed cavity. Follow-up was conducted every 4 weeks with pelvic examination and ultrasonography.. Nineteen patients with a total of 21 pelvic lymphocysts underwent this procedure. The median size of the lymphocysts was 6 cm in diameter (range, 4-9 cm). Fifteen patients received 1 treatment, 3 received 2, and 1 patient with bilateral lymphocysts received 3 treatments. Complete resolution occurred in 14 patients (74%), and the other 5 patients (26%) had partial resolution with the volume of the lymphocyst decreasing at least 50%. For the 14 patients with complete resolution, the median time from treatment to disappearance of the lymphocyst was 3 months (range, 1-10 months), and none of them developed recurrence during the average follow-up period of 40 months (range, 2-62 months). No significant complication occurred with this procedure except for transient mild to moderate pelvic pain.. Minocycline sclerotherapy seems to be a simple and safe method with a satisfactory success rate in treating lymphocysts which develop after pelvic lymphadenectomy. It can be performed in an outpatient setting and can be repeated if necessary. This procedure may be considered as the initial treatment modality for patients suffering from symptomatic or persistent lymphocysts after radical gynecological surgery.

To report changes in the white blood cell (WBC) counts in expressed prostatic secretions (EPS) in men with pelvic symptoms undergoing thrice-weekly prostatic massage combined with antimicrobial therapy.. The study comprised a retrospective analysis of the records of 35 patients (mean age 45.3 years, range 28-70, SD, 12.03) with pelvic pain, pain in the lower back, obstructive urinary symptoms, irritative urinary symptoms, or sexual dysfunction, who had undergone the same diagnosis and treatment protocol in a genitourinary clinic in Manila, Philippines, from September 1992 to September 1995.. EPS were obtained 347 times in 35 patients (median 9 times per patient, range 6-16). In 26 of the 35 (74%) patients the WBC count in the EPS was < 10 per oil-immersion field (OIF, x1000) at the first prostatic massage. In 34 of 35 (97%) patients the WBC count rose to > or = 10 as prostatic massage continued on a thrice-weekly schedule. The mean (range, SD) initial WBC count in the EPS was 8.4 (1-48, 8.43) and the maximum was 40.9 (6-60, 19.05); the difference between these values was 32.5 (3-57, 18.78; 95% confidence interval 26.1-40.1) and the difference was statistically significant (paired t-test, P < 0.001).. The classification of patients into those with prostatodynia or prostatitis based on one EPS examination is misleading and thrice-weekly massage of the prostate is better than a single collection of EPS to obtain the most purulent sample for Gram staining and culture.
