Adrenocortical hormone abnormalities in men with chronic prostatitis/chronic pelvic pain syndrome

OBJECTIVES: To identify adrenocortical hormone abnormalities as indicators of endocrine dysfunction in CP/CPPS. METHODS: We simultaneously measured the serum concentrations of 12 steroids in CP/CPPS and control patients, using isotope dilution liquid chromatography followed by atmospheric pressure photospray ionization and tandem mass spectrometry. RESULTS: Twenty-seven CP/CPPS patients and 29 age-matched asymptomatic healthy controls were evaluated. In the mineralocorticoid pathway, progesterone was significantly higher, whereas corticosterone and aldosterone concentrations were significantly lower, in CP/CPPS than in controls. In the glucocorticoid pathway, 11-deoxycortisol was significantly lower, and cortisol concentrations were not different between patients and controls. In the sex steroid pathway, androstenedione and testosterone concentrations were significantly higher in CP/CPPS than in controls. Estradiol, dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) concentrations were not different between patients and controls. NIH-CPSI total and pain domain scores correlated positively with 17-hydroxyprogesterone and aldosterone (P<0.001) and negatively with cortisol concentrations (P<0.001). CONCLUSIONS: Results suggest reduced activity of CYP21A2 (P450c21), the enzyme that converts progesterone to corticosterone, and 17-hydroxyprogesterone to 11-deoxycortisol. Furthermore, these results provide insights into the biological basis of CP/CPPS. Follow-up studies should explore the possibility that CP/CPPS patients meet the diagnostic criteria for nonclassical CAH and if hormonal findings improve or worsen in parallel with symptom severity

2017 cardiovascular and stroke endpoint definitions for clinical trials

This publication describes uniform definitions for cardiovascular and stroke outcomes developed by the Standardized Data Collection for Cardiovascular Trials Initiative and the US Food and Drug Administration (FDA). The FDA established the Standardized Data Collection for Cardiovascular Trials Initiative in 2009 to simplify the design and conduct of clinical trials intended to support marketing applications. The writing committee recognizes that these definitions may be used in other types of clinical trials and clinical care processes where appropriate. Use of these definitions at the FDA has enhanced the ability to aggregate data within and across medical product development programs, conduct meta-analyses to evaluate cardiovascular safety, integrate data from multiple trials, and compare effectiveness of drugs and devices. Further study is needed to determine whether prospective data collection using these common definitions improves the design, conduct, and interpretability of the results of clinical trials
