Intestinal microflora and inflammation are associated with the risk of inflammatory bowel diseases. Noni (Morinda citrifolia L.) has various bioactivities, but its effect on colon health remains unknown. This study focused on the effects of fermented noni fruit extracts on colon microflora and inflammation of colon epithelial cells. The anti-inflammatory activities of ethanol and ethyl acetate extracts on Caco-2 cells were evaluated including interleukin-8 (IL-8) and cyclooxygenase-2 (COX-2). The growth of Lactobacillus and Bifidobacterium species was promoted by ethanol extract. Ethyl acetate extract decreased intracellular reactive oxygen species and significantly suppressed COX-2, IL-8, and prostaglandin E2 production and neutrophil chemotaxis by suppressing the translocation of the p65 subunit. Quercetin was the main contributor to the anti-inflammatory activity. The fermented noni fruit promoted probiotic growths and downregulated the intracellular oxidation and inflammation in Caco-2 cells. These results suggest that fermented noni fruit might protect against inflammatory diseases of the colon.

Purpose: To investigate the changes in urinary nerve growth factor (uNGF) levels after acute urinary tract infection (UTI) and to assess the role of uNGF in predicting UTI recurrence in women. Methods: Women with uncomplicated, symptomatic UTIs were enrolled. Cephalexin 500 mg (every 6 hours) was administered for 7–14 days to treat acute UTIs. Subsequently, the patients were randomized to receive either sulfamethoxazole/trimethoprim 800 mg/160 mg daily at bedtime, or celecoxib 200 mg daily for 3 months and were monitored for up to 12 months. NGF levels in the urine were determined at baseline, 1, 4, and 12 weeks after the initiation of prophylactic therapy, and were compared between women with first-time UTIs and recurrent UTIs, sulfamethoxazole/trimethoprim and celecoxib-treated women, and no UTI recurrence and UTI recurrence that occurred during the follow-up period. Twenty women free of UTIs served as controls. Results: A total of 139 women with UTI and 20 controls were enrolled in the study, which included 50 women with a firsttime UTI and 89 women with recurrent UTIs. Thirty-seven women completed the study. Women with recurrent UTIs (n=23) had a trend of lower uNGF levels than women with first-time UTIs (n=14). During follow-up, 9 women had UTI recurrence. The serial uNGF levels in women with UTI recurrence were significantly lower than those in women who did not have UTI recurrence during the follow-up period. Conclusions: The lower levels of uNGF in women with recurrent UTI and the incidence of UTI recurrence during follow-up suggest that lower uNGF might reflect the defective innate immunity in women with recurrent UTI.
