Background Chronic rhinosinusitis (CRS) is one of the most common diseases with no specific long-term treatment. CRS can present in two phenotypes: chronic rhinosinusitis without nasal polyps (CRSsNP) and chronic rhinosinusitis with nasal polyps (CRSwNP). Vitamin D (VD) is considered to have an immunomodulatory role, especially in allergic diseases. Recent studies have found that patients with CRS have VD level lower than normal, especially patients with CRSwNP. Aim The aim of this study was to systematically evaluate and find out whether there is a relationship between serum VD level and CRS and its phenotypes. Materials and methods Using Medline database, we conducted a systematic search to find all related articles published up to 31 August 2016 using the keywords Vitamin D, allergic rhinitis, CRSwNP, and CRSsNP and applying certain inclusion and exclusion criteria. Results Six articles were included with a total number of participants of 309 with serum VD level. Four comparisons were made. The first comparison showed no statistically significant difference in VD level between the CRSsNP and the control group. The second comparison showed a statistically significantly lower VD level in the CRSwNP group than in the control group. The third comparison showed a statistically significantly lower VD level in the CRSwNP than in the CRSsNP group. The last comparison showed no statistically significant difference in VD level between CRS with or without nasal polyps and controls. Conclusion VD level was significantly low in patients with CRSwNP, which might have a causative relationship. However, there was no relation between VD level and CRSsNP.
