title: Chronic Rhinosinusitis and Irritable Bowel Syndrome: A Case Report.
abstract: BACKGROUND
  Chronic rhinosinusitis (CRS) and irritable bowel syndrome (IBS) can be comorbidities that are difficult to treat. In this patient, an evidence-informed treatment pathway guided by laboratory biomarkers was used to address both conditions.
  
  
  METHODS
  A 69-y-old female patient presented with a 50-y history of sinusitis that was worse in the winter, postnasal drip, frequent sore throats, gastrointestinal complaints, headaches, and yeast infections. Two sinus surgeries (in years 2000 and 2002) and multiple courses of antibiotics had not resolved her sinus symptoms. In addition to CRS and IBS, this patient was noted to have intestinal overgrowth of Candida albicans, multiple food sensitivities, and leaky gut syndrome.
  
  
  CONCLUSIONS
  Antifungal medication and dietary changes in the course of 8 mo resulted in the resolution of her CRS and IBS.
