The aim of this study was to compare the frequency of metabolic syndrome (MetS) in patients with and without interstitial cystitis/bladder pain syndrome (IC/BPS).
This case-control study evaluated the indicators of MetS in 287 females with IC/BPS and in 287 females without IC/BPS in West China Hospital between January 2010 and January 2020. Then, the number of voids per day, frequency of night urination, O'Leary-Sant Interstitial Cystitis Symptom/Problem Index, and visual analog scale were examined in the two groups.
Based on both the National Cholesterol Education Program Adult Treatment Panel III recommendations and the International Diabetes Federation criteria, the distribution of MetS was statistically higher in patients with IC/BPS than in the control group, with 34.8% vs 17.8% (P < 0.0001) and 34.2% vs 20.9% (P = 0.0005), respectively. Regarding symptom scores, the IC/BPS group demonstrated significantly higher scores than the control group in all aspects (P < 0.0001). More patients with anxiety (P < 0.0001), insomnia (P < 0.0001), hypertension (P = 0.0001), and diabetes mellitus (P = 0.017) were observed in the IC/BPS group. Moreover, the findings indicated that patients with IC/BPS had a higher BMI (P = 0.0001) and larger waist circumference (P = 0.0001). Blood tests presented a significantly higher level of fasting glycemia, serum cystatin-C, and triglycerides in patients with IC/BPS. Furthermore, higher ORs for the occurrence of MetS among cases were observed, although this was not statistically significant.
MetS frequency was relatively high in patients with IC/BPS. Further research is needed to understand the common pathophysiologic mechanism of IC/BPS and MetS.
