It is characterised by bladder wall inflammation, defective bladder urothelium, and increased levels of the pro-inflammatory cytokine TNF-α in the bladder tissue. The release of TNF-α by the urothelial cells further aggravates the inflammatory response in patients with IC/BPS. Commonly, Medical grade Manuka honey (Medihoney® (MH)) possesses strong pro-angiogenic and anti-microbial properties. Our recent findings have highlighted its anti-inflammatory effects through inhibition of induced mast cell degranulation. In addition, we demonstrated that MH is well tolerated by the rat urothelial cells where it was cytoprotective against acid damage. In the present study, we investigated the cytotoxic and anti-inflammatory effects of MH using an in vitro model of primary human urothelial cells (HUCs). METHODS: Cytotoxic effect of various concentrations of MH on HUCs at 1, 24, 48, and 72 hours was evaluated using MTT assay. In addition, the release of the pro-inflammatory cytokines IL-8 and IL-6 in the HUCs after 24-hour incubation with TNF-α (10 ng/ml) with/without pre-treatment with 4% MH was assessed using ELISA assays. RESULTS: One hour incubation with MH (2%, 4%, 6% and 8% w/v) did not induce significant cytotoxic effects on the HUCs. However, when the cells were incubated with MH for a longer periods, we observed an incremental cytotoxic effect, especially at 6% and 8% (Figure 1). In addition, 4% MH significantly decreased the TNF-α induced release of IL-6 and IL-8 in the urothelial cells (Figure 2). CONCLUSIONS: Our results indicate that MH is not cytotoxic to urothelial cells and has potential use as an intravesical therapeutic agent for the management for bladder inflammatory conditions such as IC/BPS.
