OBJECTIVES: Vitamin D may play an important role in immunity and its deficiency has been related to increased respiratory infections. The aim of this study was to detect the prevalence of vitamin D deficiency and to investigate the relationship between radiological and clinical effects on adult bronchiectasis (BR) patients.
MATERIALS AND METHODS: A total of 130 patients with BR and 73 healthy individuals (control group) were enrolled in this study. Radiological severity was assessed using Modified Reiff Score.
RESULTS: The mean age of patients was 41.9±9.1 years (range, 18–85). The mean 25-hydroxyvitamin D (25(OH)D) level was 14.7±9.6 ng/mL in BR patients and 19.8±6.9 ng/mL in the control group (p=0.001). Moreover, 95 (73.1%) adult BR patients were categorized as vitamin D deficient. Patients in the vitamin D deficiency group had significantly higher Modified Medical Research Council scores than those in the group without vitamin D deficiency (p=0.036) The mean modified Reiff score was higher in the vitamin D deficient group than the without vitamin D deficiency group (6.9±3.8 vs 4.9± 2.7, p=0.001). Additionally, the vitamin D deficient group had lower forced vital capacity% predicted value (p=0.02). This model showed that Reiff score (OR, 1.285[1.039–1.590]; p=0.021) was independently related to vitamin D deficiency.
CONCLUSION: We found that vitamin D deficiency is commonly seen in adult BR patients in a stable period. Moreover, it might be related to severe radiological findings on chest computed tomography and worse lung functions.
