ABSTRACT
Background: South Africa experienced five COVID-19 waves and over 90% of the population have developed immunity. HIV prevalence among adults is 19% and over 2 million people have uncontrolled viral loads, posing a risk for poor COVID-19 outcomes. Using national hospital surveillance data, we aimed to investigate trends in admission and factors associated with in-hospital COVID-19 mortality among people with HIV (PWH) in South Africa. Method(s): Data between March 5, 2020 and May 28, 2022 from the national COVID-19 hospital surveillance system, SARS-CoV-2 case linelist and Electronic Vaccine Data System were linked and analysed. A wave was defined as the period for which weekly incidence was >=30 cases/100,000 people. Descriptive statistics were employed for admissions and mortality trends. Postimputation random effect multivariable logistic regression models compared (a) characteristics of PWH and HIV-uninfected individuals, and (b) factors associated with mortality among PWH. Result(s): 68.7% (272,287/396,328) of COVID-19 admissions had a documented HIV status. PWH accounted for 8.4% (22,978/272,287) of total admissions, and 9.8%, 8.0%, 6.8%, 12.2% and 6.7% of admissions in the D614G, Beta, Delta, Omicron BA.1 and Omicron BA.4/BA.5 waves respectively. The case fatality ratio (CFR) among PWH and HIV-uninfected was 24.3% (5,584/22,978) vs 21.7% (54,110/249,309) overall, and in the respective waves was 23.7% vs 20.4% (D614G), 27.9% vs 26.6% (Beta), 26.2% vs 24.5% (Delta), 18.2% vs 9.1% (Omicron BA.1) and 16.8% vs 5.5% (Omicron BA.4/BA.5). Chronic renal disease, malignancy and past TB were more likely, and hypertension and diabetes were less likely in PWH compared to HIV-uninfected individuals. Among PWH, along with older age, male sex and presence of a comorbidity, there was a lower odds of mortality among individuals with prior SARS-CoV-2 infection (aOR 0.6;95% CI 0.4-0.8);>=1 dose vaccination (aOR 0.1;95% CI 0.1-0.1);and those admitted in the Delta (aOR 0.9;95% CI 0.8-0.9), Omicron BA.1 (aOR 0.5;95% CI 0.5-0.6) and Omicron BA.4/BA.5 (aOR 0.5;95% CI 0.4-0.7) waves compared to the D614G wave. PWH with CD4< 200 had higher odds of in-hospital mortality (aOR 1.9;95% CI 1.8-2.1). Conclusion(s): In South Africa, mortality among PWH was less likely in the Delta and Omicron waves but PWH had a disproportionate burden of mortality during the two Omicron waves. Prior immunity protected against mortality, emphasizing the importance of COVID-19 vaccination among PWH, particularly PWH with immunosuppression.
ABSTRACT
Objective: Few data have been published regarding the holistic approach of post- Covid patients, examining physical health. The purpose of our study was to examine the impact of arterial hypertension in the cardiopulmonary status of post-covid patients 3 months after the first day of infection. Design and Method: All participants who recovered Covid-19 infection underwent cardiorespiratory exercise using either Bruce or modified Bruce protocol where all parameters were evaluated and transthoracic echocardiogram. The population was separated into two groups based on history of hypertension. Group I (n = 29) included hypertensive subjects and Group II (n = 75) included normotensive subjects. Results and Conclusion: A total of 104 patients were assessed 3 months after the onset of COVID-19 symptoms. We recorded a mean age of 49 ± 15 years, 50.5% of them were males, 8.7% had a history of coronary heart disease. Hypertensives had higher BMI (29.24 ± 24 vs 26.64 kg/m2 p < 0.01) and BSA (2.09 ± 0.25 vs. 1.95 ± 0.58, p = 0.001). They were hospitalized in higher percentage comparing to normotensives (72.4% vs. 41.3%, p < 0.01). Left atrial diameter (41 ± 6 vs. 35 ± 5.5 mm, p < 0.001) was significantly larger in hypertensives. Furthermore, A wave (79 ± 21 vs. 58 ± 18 cm/s p < 0.001) and ratios of E/A (1.01 ± 0.42 vs. 1.28 ± 0.44, p < 0.01) and E/E (7.3 ± 3.7 vs. 5.9 ± 4.3, p < 0.01) differed between two groups. Finally, LVEF (%) was significantly impaired in hypertensive comparing to normotesive subjects (53 ± 13% vs. 59 ± 7%). This finding was depicted in lower maximum oxygen consumption (VO2 22 ± 4.5 vs. 28 ± 8 ml/kg/min p < 0.001), metabolic equivalents (METS) at peak, 9.1 ± 3 vs. 14 ± 20 p < 0.001), maximum heart rate (maxHR 147 ± 17 vs. 165 ± 21 bpm p < 0.001) and HR1st minute recovery (123 ± 28 vs. 138 ± 21 bpm, p: 0.02) comparing to normotensive. Systolic blood pressure (SBP 180 ± 29 vs. 165 ± 25mmHg, p: 0.02) during the 1st minute of recovery was higher in hypertensives. Finally, the duration of exercise was significantly lower in patients with hypertension (7.3 ± 2.7 vs. 9 ± 4 min, p:0.02). To conclude, the current study highlighted the negative impact of hypertension in the ability to exercise. Regardless of the disease severity, post-covid patients need a comprehensive approach for rehabilitation including the modification of risk factors like hypertension and obesity.
