Popis:	Vitamin D has been demonstrated to have an immunomodulatory role in cystic fibrosis with allergic bronchopulmonary aspergillosis (ABPA). Herein, we evaluate supplemental vitamin D in acute-stage ABPA complicating asthma. Thirty subjects were randomised to receive either prednisolone (n = 15, control) or prednisolone and oral vitamin D (n = 15, intervention arm). Serum vitamin D levels were significantly higher in the intervention versus the control arm, following therapy. The mean decline in total IgE at 2 months (primary outcome) was 10% higher in the intervention arm than the control arm; however, this was not statistically significant (48.6% vs 38.1%, P = 0.27). The percentage decline in total IgE after 4 and 6 months of randomisation was also similar in the two arms. There was no difference in asthma exacerbations (0 vs 2, intervention vs control; P = 0.16). No ABPA exacerbation occurred in either arm. The other outcomes including the Th2 (IL-4, IL-6 and IL-10) and Th17 (IL-17) cytokine levels were similar in the two groups. None of the participants experienced hypervitaminosis D. There was no significant improvement in the clinical or immunological outcomes following vitamin D supplementation. A larger trial is required to ascertain the role of vitamin D in ABPA complicating asthma [Clinicaltrials.gov: NCT03133299].
