Pediatric COVID-19 and Gastrointestinal Symptoms in Africa

Test positivity and clinical presentation of COVID-19 in Mozambican infants hospitalized during the second wave of the pandemic in 2021

Introduction

during the second wave of the COVID-19 pandemic in Mozambique, there was a surge in pediatric hospitalizations at a time when there was relatively little evidence, but significant concern about clinical outcomes in African children, particularly in higher-risk infants requiring, and health system capacity to respond.

Methods

a retrospective cohort study was conducted for patients 1-12 months of age admitted to the Breastfeeding ward at Hospital Central de Maputo from January-February 2021. All had routine SARS-CoV-2 PCR testing performed. For patients with positive results, hospital charts were retrospectively reviewed. Descriptive analyses were performed.

Results

of 209 patients that had SARS-CoV-2 PCR testing performed, 102 (48.8%) received results, of which 37 (36.3%) were positive. Positive results were received prior to discharge for 14 patients (37.8%). Median duration of hospitalization was 3 days. There were two deaths in COVID-positive patients (5.4%), both with complex comorbidities. For the 35 COVID-19 positive patients whose charts were located, the principal admission diagnosis was respiratory for 22 (62.9%), and 14 (40.0%) had oxygen saturation <94% at admission. The white blood cell count was >12.0 x 10³cells/mL in 10 patients (28.6%) and the most common abnormal finding on chest radiograph was peribronchial thickening (38.5% of patients with results). Oxygen therapy was needed for 20 patients (57.1%).

Conclusion

the majority of infants with COVID-19 had a mild, short-duration respiratory illness that did not exceed ward capacity for care, including oxygen treatment. Laboratory capacity for PCR testing was overwhelmed, delaying the return of results and complicating inpatient infection control measures.

Symptomatic, clinical and biomarker associations for mortality in hospitalized COVID-19 patients enriched for African Americans

BACKGROUND AND AIMS

Initial reports on US COVID-19 showed different outcomes in different races. In this study we use a diverse large cohort of hospitalized COVID-19 patients to determine predictors of mortality.

METHODS

We analyzed data from hospitalized COVID-19 patients (n = 5852) between March 2020- August 2020 from 8 hospitals across the US. Demographics, comorbidities, symptoms and laboratory data were collected.

RESULTS

The cohort contained 3,662 (61.7%) African Americans (AA), 286 (5%) American Latinx (LAT), 1,407 (23.9%), European Americans (EA), and 93 (1.5%) American Asians (AS). Survivors and non-survivors mean ages in years were 58 and 68 for AA, 58 and 77 for EA, 44 and 61 for LAT, and 51 and 63 for AS. Mortality rates for AA, LAT, EA and AS were 14.8, 7.3, 16.3 and 2.2%. Mortality increased among patients with the following characteristics: age, male gender, New York region, cardiac disease, COPD, diabetes mellitus, hypertension, history of cancer, immunosuppression, elevated lymphocytes, CRP, ferritin, D-Dimer, creatinine, troponin, and procalcitonin. Use of mechanical ventilation (p = 0.001), shortness of breath (SOB) (p < 0.01), fatigue (p = 0.04), diarrhea (p = 0.02), and increased AST (p < 0.01), significantly correlated with death in multivariate analysis. Male sex and EA and AA race/ethnicity had higher frequency of death. Diarrhea was among the most common GI symptom amongst AAs (6.8%). When adjusting for comorbidities, significant variables among the demographics of study population were age (over 45 years old), male sex, EA, and patients hospitalized in New York. When adjusting for disease severity, significant variables were age over 65 years old, male sex, EA as well as having SOB, elevated CRP and D-dimer. Glucocorticoid usage was associated with an increased risk of COVID-19 death in our cohort.

CONCLUSION

Among this large cohort of hospitalized COVID-19 patients enriched for African Americans, our study findings may reflect the extent of systemic organ involvement by SARS-CoV-2 and subsequent progression to multi-system organ failure. High mortality in AA in comparison with LAT is likely related to high frequency of comorbidities and older age among AA. Glucocorticoids should be used carefully considering the poor outcomes associated with it. Special focus in treating patients with elevated liver enzymes and other inflammatory biomarkers such as CRP, troponin, ferritin, procalcitonin, and D-dimer are required to prevent poor outcomes.
