Summary

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.

Conditions

  • COVID-19
  • Lung Function Decreased
  • Xray Complication

Interventions

DIAGNOSTIC_TEST

Pulmonary function test

Spirometry was performed by trained nurse at division of pulmonology, Vajira hospital. The forced vital capacity (FVC), forced expiratory volume in first second of exhalation (FEV1), forced mid-expiratory flow (FEF25-75%), and the FEV1/FVC ratio before and after bronchodilators (2 puffs of salbutamol via spacer) were collected in all cases. Total lung capacity (TLC) using the spirometry (Masterscreen PFT, Jaeger, Germany) and diffusion capacity of carbon monoxide was performed in selected case with abnormalities of lung parenchyma found from computed tomography of the chest.

DIAGNOSTIC_TEST

Chest computer scan

High-resolution computed tomography (HRCT) was performed in a single breath-hold on a 128 slice multidetector computed tomography (MDCT) scanner (Philips Healthcare Nederland B.V, Ingenuity 128, Netherlands). HRCT was performed with the patient in the supine position during end-inspiration, supine position during end-expiration, and prone position during end-inspiration with 1 millimeter (mm) slice thickness.
