Abstract

Cystitis means inflammation of the bladder, specifically inflammation of bladder wall. Evaluating the level of urinary MMP-9 as a prognostic biomarker in cystitis (schistosomal and non schistosomal) was the aim of the study. Urine samples and bladder biopsies were collected from 50 cystitis patients who were included schistosomal chronic cystitis and non schistosomal cystitis and also from 38 healthy individuals as control. Urinary concentration of MMP-9 was measured by ELISA technique. Specificity and sensitivity of marker were also calculated. The results showed that MMP-9 urinary level was significantly increased in cystitis patients (3842.90pg/ml) compared to healthy (634.80pg/ml), there was a significant differences in the mean levels of urine MMP-9 for different age groups of patients, but non-significant between females and males. MMP-9 was elevated in both schistosomal chronic cystitis and non-schistosomal cystitis patients and this elevation of marker was higher in schistosomal chronic cystitis but with non-significant, also urine MMP-9 showed significant increase in males than females schistosomal cystitis, and statistical differences between age groups. Matrix Metalloproteinase was specific (87.47%) and was more sensitive (93.22 %) in cystitis patients. We concluded that MMP-9 has a role in inflammation processes of cystitis.
