To investigate the association between the urinary levels of prostaglandins (PGE(2) and PGF(2α)), nerve growth factor (NGF) and substance P, and overactive bladder (OAB) symptoms in patients with suprapontine brain diseases.. The subjects were 114 patients in the chronic phase of a brain disease and 27 healthy controls with no brain disease or lower urinary tract symptoms (LUTS). The OAB symptoms were assessed with the OAB symptom score and the subjects were then classified into 5 groups: healthy control, patients without LUTS, increased bladder sensation (IBS), OAB dry, and OAB wet. Urinary mediator concentrations were measured using enzyme-linked immunosorbent assay and normalized to the urinary creatinine concentration, and then compared among the 5 groups.. The urinary PGE(2) level was significantly higher in patients with brain diseases than in healthy controls, even in the patients without any OAB symptoms, and compared with patients without LUTS, a significant increase in the urinary PGE(2) was observed in patients with OAB dry or wet (P = .004 or .015, respectively). The PGF(2α) level showed a significant increase in OAB wet compared with patients without LUTS (P = .001). The urinary levels of NGF and substance P were not significantly associated with OAB as a result of this type of brain disease.. The urinary PGE(2) level was putatively elevated in patients with suprapontine brain diseases and associated with the presence of OAB. The PGF(2α) level may also be associated with OAB.

Oxidative stress and NO are thought to play important roles in arteriosclerosis pathogenesis, a major cause of white matter lesions in the brain. Therefore, we examined whether NO metabolites (NOx) and 8-iso-prostaglandin F(2alpha) (IsoP) levels in vivo correlated with the severity of periventricular hyperintensity (PVH) to evaluate potential roles of oxidative stress and NO in white matter lesions.. Participants (687 males and 528 females) of a health-screening examination were recruited into the study. The plasma NOx and urinary IsoP levels were measured using the Griess method and ELISA, respectively. PVH was diagnosed on the basis of MRIs. In nonparametric univariate trend analyses, plasma NOx as well as aging, presence of hypertension and of lacunes, mean blood pressure, and high-density lipoprotein cholesterol showed highly significant monotone correlation with PVH severity (P
