Long Term Sequelae of COVID-19: Follow-up Study in Dhaka, Bangladesh

Summary

COVID-19 or coronavirus disease 2019 is an emerging infectious disease. The disease was first identified in China and then spread worldwide; hence, declared as a global pandemic on March 11, 2020 by World Health Organization (WHO). The pandemic is posing formidable challenges to healthcare systems and humanities worldwide resulting in morbidities and mortalities unthought of. Rapidly accumulating clinical evidence on COVID-19 paved the way for an extensive and prompt characterization of the acute phase of the disease. The clinical presentation is generally that of a respiratory infection with a symptom severity ranging from a mild common cold-like illness, to a severe viral pneumonia leading to acute respiratory distress syndrome that is potentially fatal. Characteristic symptoms include fever, cough, and dyspnoea, although some patients may be asymptomatic. Complications of severe disease include, but are not limited to, multi-organ failure, septic shock, and acute respiratory distress syndrome. The COVID-19 infection fatality rate is between 0.5 and 1 percent and the remaining affected patients will mostly recover but need convalescent care. However, discharge should not be considered as the final point of overcoming coronavirus and till date evidence on sequelae of the COVID-19 recovered patients is very limited. COVID-19 is a complex multisystem disease that affects pulmonary function, as well as renal, cardiovascular, and neuropsychiatric health, metabolic derangement; and nutritional status. The extent to which these alterations may persist remains obscure, till date evidence on long term sequelae of the COVID-19 recovered patients is very limited. Some of the aftereffects of it may have a profound impact on 'recovered' patients in the future.

Long-term morbidities were observed in survivors of severe acute respiratory syndrome but it is unidentified whether experience from SARS is applicable to COVID-19. The SARS-CoV-2 infection is severe in older, immune deficient people and who have any pre-existing medical conditions. Hence, it is imperative to comprehend the possible long-term sequelae of the COVID-19 recovered patients, and if they will develop any other harmful illnesses. This study would help us to understand the in-depth prognosis and sequelae of the disease, as well as help to uncover to what extent would COVID-19 recovered patients require post-acute care to recuperate from any further infections or multi-organ damage.

Observational study

\- Baseline data of prognostic importance, including demographic, social information, lifestyle factors, medical history, underlying comorbidities, anthropometric measurements, clinical, laboratory, imaging and treatment records will be collected using a standard case report form. A detailed clinical examination including measurement of vital signs, blood pressure, pulse oximetry, anthropometric measurements, neurological, pulmonary, cardiovascular system examination, mental and fuctional status assessment. routine laboratory assays including complete blood count (CBC), serum alanine transaminase (ALT), serum creatinine, fasting capillary blood glucose using glucometer and urine routine examination, ECG, echocardiography, chest X-ray and pulmonary function test. Additional tests when required such as fasting blood sugar, glycated haemoglobin, MRI/CT scan of brain, Thyroid function tests such as FT4, FT3 and TSH and C peptide etc
