Effect of amitriptyline in treatment interstitial cystitis or bladder pain syndrome according to two criteria: does ESSIC criteria change the response rate?
ESSIC criteria did not decrease the response rate of amitriptyline treatment for BPS patients compared to IC patients with complaint of bladder pain or discomfort. Cystoscopy showed no predictive effect for the treatment outcome of amitriptyline.
We conclude that the two investigated techniques yield results with an acceptable agreement. The agreement of both measurements indicates a good external consistency and reliability of both analytical methods. In the absence of a gold standard for ghrelin measurement, our data are a cross-validation for both methods.
