Brief Summary: This study seeks to address the limitations in previous related studies on vitamin D replacement and bronchiectasis exacerbation occurrence through a self-controlled pilot study The investigators aim to investigate whether vitamin D replacement in bronchiectasis patients with vitamin D deficiency can reduce hospitalized bronchiectasis exacerbation occurrence Patients who participated in the prior study entitled Prospective clinical study on serum 25-hydroxyvitamin D 25-OH D level and risk of bronchiectasis exacerbation UW 22-317 will be invited for participation during regular clinic follow-up and management in Queen Mary Hospital If participants are willing to join the further research participants will be recruited in this self-controlled study There are some differences from usual management to non-CF bronchiectasis subjects The study subjects would be checked for their blood 25-hydroxyvitamin-D level during the study period The non-CF bronchiectasis subjects with Vitamin D deficiency would be given 1000 IU and 2000 IU if needed The investigators aim to correct their Vitamin D deficiency completely aiming at blood 25-hydroxyvitamin-D level 50 ie treat to target The dose depends on the level of Vitamin D after replacement If blood 25-hydroxyvitamin-D level is 50 or above then 1000 IU is suffice If blood 25-hydroxyvitamin-D level is still below 50 the investigators will increase to 2000 IU
