title: [Identification of microorganisms related to chronic rhinosinusitis in adult patients with variable common immunodeficiency].
abstract: The prevalence of chronic rhinosinusitis in adult patients with common variable immunodeficiency (CVID) is 52%. The patients with CVID show higher incidence of chronic rhinosinusitis, which is an inflammatory disease that affects the lining of one or more paranasal sinuses and nasal cavity.
  
  
  
  To identify the microorganisms in the middle meatus secretion obtained by endoscopy associated with chronic rhinosinusitis in adult patients with common variable immunodeficiency (CVID).
  
  
  
  A descriptive, cross-sectional study, which included adult patients with CVID, from whom a sample endoscopic middle meatus secretion from both nostrils was obtained and sent to culture for aerobic, anaerobic bacteria and fungi. Informed consent of all patients was obtained.
  
  
  
  29 patients were studied: 18 women and 11 men with a mean age of 40±13 years. The results were: 2 samples showed no microbial growth, 24 showed growth of aerobic bacteria, 3 cases had fungal growth without development of anaerobic bacteria.
  
  
  
  Our results show that the most common microorganisms associated with CSR in adult patients are: Moraxella catarrhalis, Staphylococcus, Sphingomonas paucimobilis and Citrobacter koseri, and associated fungal agents were: Candida albicans and Aspergillus fumigatus.
