About

COVID-19 is associated with increased morbidity and mortality in patients with chronic kidney disease (CKD) on dialysis. CKD requires particular emphasis during the pandemic due to concern for increased susceptibility to infection from greater use of health facilities in people undergoing maintenance hemodialysis. COVID-19 due to SARS-CoV-2 involves multiple organs and lung injury is one of the most clinical manifestations. The binding of SARS-CoV-2 to the ACE2 receptors at target cells ,including type II pneumocytes ,and alveolar macrophages in the lung could arise into acute systemic inflammatory responses and cytokine storm.The consequentially leading to lung-resident dentritic cells (rDCs) activation, T lymphocytes production and release antiviral cytokines into the alveolar septa and interstitial compartments resulting in diffuse alveolar epithelium destruction,hyaline membrane formation, alveolar septal fibrous proliferation and pulmonary fibrosis.Although it has been reported that subgroups of COVID-19 survivors developed persistent lung parenchymal injury that persisted at least after 6 months 5-6 ,the data in CKD patients has not been reported yet.In addition, a study of pulmonary function test after COVID-19 is needed to be investigated.Thus,we plan to assess pulmonary sequalae of COVID-19 in hemodialysis (HD) patients and pulmonary function test after recovered of infection at least 3 months.

Full description

This is the prospective,observational cohort study including CKD stage 5 on hemodialysis who survived acute COVID-19 and presented for clinical follow-up after either mild/moderate or severe COVID-19.The study was conducted at Faculty of Medicine ,Vajira Hospital ,Navamindradhiraj University from June 2022 -September 2022.We adhered to the Declaration of Helsinki,and all patients provided written informed consent before inclusion.Ethics approval was obtained from Institutional Review Board (IRB) prior to start of the study (COA No 302/64 E).
