Severity of COVID-19 in bacillus Calmette-Guérin vaccinated population
Iffat Khanum,Lokesh Kumar,Safia Awan,Bushra Jamil 대한백신학회 2021 Clinical and Experimental Vaccine Research Vol.10 No.3
Purpose: Considering the cross-protection reported for bacillus Calmette-Guérin (BCG) vaccination on viral respiratory infections, it has been proposed that it could reduce the severity of coronavirus disease 2019 (COVID-19). The objective of the current study is to investigate the association between the severity of COVID-19 with prior BCG vaccination in adult patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Materials and Methods: Adult patients (18 years or above) with positive SARS-CoV-2 polymerase chain reaction admitted in July 2020 were included in this cross-sectional study. Patients were classified into non-severe, severe, and critical diseases. History of prior BCG vaccination and the presence of a BCG vaccination scar were recorded. Results: Out of 103 patients, 64 patients with prior history of BCG vaccinations were compared with 39 patients without BCG vaccination in childhood. The median age was 55 years and 64 years in BCG vaccinated & non-BCG vaccinated patients (p-value=0.002). There was male predominance in both groups and frequent comorbid illnesses were hypertension and diabetes mellitus. Severe COVID-19 was found in 91 patients (88.3%) followed by non-severe disease and critical diseases i.e., 7 (6.8%) and 5 (4.9%) patients, respectively. No association of prior BCG vaccination with disease severity of COVID-19 was found in this study and mortality was 8.7%. Out of nine patients who expired only 2 (22.2%) had a prior history of BCG vaccination (p-value=0.01). Secondary infections were present in 26 patients and the majority had pneumonia. Conclusion: The BCG vaccine has no impact on the severity of COVID-19 but could have a protective role with a low mortality rate in already infected patients.

Risk factors for intensive care unit admission and mortality in hospitalized COVID-19 patients
Ayaz Ahmed,Arshad Ainan,Malik Hajra,Ali Haris,Hussain Erfan,Jamil Bushra 대한중환자의학회 2020 Acute and Critical Care Vol.35 No.4
Background: This study investigated the clinical features and outcome of hospitalized coronavirus disease 2019 (COVID-19) patients admitted to our quaternary care hospital. Methods: In this retrospective cohort study, we included all adult patients with COVID-19 infection admitted to a quaternary care hospital in Pakistan from March 1 to April 15, 2020. The extracted variables included demographics, comorbidities, presenting symptoms, laboratory tests and radiological findings during admission. Outcome measures included in-hospital mortality and length of stay. Results: Sixty-six COVID-19 patients were hospitalized during the study period. Sixty-one percent were male and 39% female; mean age was 50.6±19.1 years. Fever and cough were the most common presenting symptoms. Serial chest X-rays showed bilateral pulmonary opacities in 33 (50%) patients. The overall mortality was 14% and mean length of stay was 8.4±8.9 days. Ten patients (15%) required intensive care unit (ICU) care during admission, of which six (9%) were intubated. Age ≥60 years, diabetes, ischemic heart disease, ICU admission, neutrophil to lymphocyte ratio ≥3.3, and international normalized ratio ≥1.2 were associated with increased risk of mortality. Conclusions: We found a mortality rate of 14% in hospitalized COVID-19 patients. COVID-19 cases are still increasing exponentially around the world and may overwhelm healthcare systems in many countries soon. Our findings can be used for early identification of patients who may require intensive care and aggressive management in order to improve outcomes.
