RESUMO
Introduction: Millions of deaths and co-morbidities have been brought on by the COVID-19 epidemic worldwide. Acute respiratory distress syndrome (ARDS), multiple organ failure, and death can result from the condition in some people. The disease's course can range from a moderate upper respiratory tract infection to severe pneumonia. Numerous reports have been made on the occurrence of pneumothorax in COVID-19 ICU patients, particularly in those who are receiving invasive ventilation. This study assesses factors associated with pneumothorax among mechanically ventilated COVID-19 ICU patients in Addis Ababa, Ethiopia. Methods: A case-control study design was employed from August 1, 2022, to August 31, 2022, GC, with a sample size of 281, where cases are 94 and controls are 187. A pre-tested structured quantitative tool was used to collect data on ODK and export it to SPSS version 26 for analysis. Descriptive statistics were presented using text and tables. The association between variables was analyzed with binary logistic regression. A statistical significance was declared at a p-value of 0.05 with a 95% confidence interval. Assumptions like model fitness and multicollinearity were checked to be satisfied. Results: A total of 281 (94 cases and 187 controls) patient charts were carefully reviewed. After adjustment for possible confounders in multivariate analysis, ARDS (AOR = 0.214, 95% CI (0.088, 0.519), P value =0.001) and invasive ventilation (AOR = 0.311, 95% CI (0.121, 0.796), P value =0.015) had a significant association with pneumothorax. Conclusion: Despite the introduction of preventive breathing methods, pneumothorax is still a frequent and deadly consequence in COVID-19 patients with ARDS. ARDS and invasive mechanical ventilation were found to be significantly associated with the development of pneumothorax. Health facilities should be well equipped with recent medical equipment in intensive care units and with well-trained and organized manpower.
RESUMO
BACKGROUND: The COVID-19 pandemic has been linked to chronic pulmonary complications all over the world. Respiratory complications such as chronic cough, dyspnea, increased respiratory rate, and oxygen support demand are prevalent in recovered COVID-19 patients. These problems are long-term and have a negative impact on one's quality of life. Patients must be evaluated for potential complications, and risk factors must be found. Some reports around the world explain the factors that contribute to the development of these complications. However, to the best of our understanding, no reports of post-COVID-19 complications have been reported from Ethiopia. METHODS: Facility based cross-sectional study was done among 405 participants selected by simple random sampling technique. Structured questionnaire which includes participants' demographic, clinical and 3rd month visit characteristics was collected by Open Data Kit and exported to SPSS version 25.0 for analysis. Percentage with frequency and median with Interquartile range was used in descriptive statistics. The association between variables was analyzed with bivariate and multi variable logistic regression. A statistical significance was declared at p-value < 0.05, with 95% confidence interval. RESULTS: The median (Interquartile range) age of participants was 57.0 (43.0, 65.0) years, 63.2% were males. The prevalence of post-COVID-19 pulmonary complication in recovered COVID-19 patients was 14.1% (95% CI: 10.8%, 17.8%). After adjusting for possible confounders on multivariate analysis, older age [AOR = 0.227, 95% CI (0.08-0.66)] and consolidation [AOR = 0.497, 95% CI (0.258-0.957)] were shown to have significant association with post COVID-19 pulmonary complications. CONCLUSION: The prevalence of post COVID-19 pulmonary complication was observed to be lower than other reports globally. Older age and the presence of consolidation on lung imaging were associated with those complications. Clinicians are recommended to consider assessing the lasting effects of the pandemic, beyond immediate care, and should also investigate the COVID-19 history in patients presenting with respiratory issues.

BACKGROUND: Studies have indicated that hospitalized COVID-19 patients benefit from anticoagulation therapy in terms of survival; however, there is an ongoing controversy over the optimum anticoagulant dosage. This study aimed to compare clinical outcomes between patients who received prophylactic anticoagulation and those who received therapeutic anticoagulation. METHODS: A multi-center retrospective cohort study was conducted to determine the impact of anticoagulation dosage in hospitalized COVID-19 patients in Ethiopia. The primary outcome measure was in-hospital mortality, and it was assessed using multivariable binary logistic regression and covariate-adjusted Cox Proportional Hazard model. For critical and severe COVID-19 patients, subgroup analyses were performed using multivariable binary logistic regression model and multivariable Cox regression models. RESULT: A total of 472 hospitalized COVID-19 patients were included in this study, of whom 235 (49.8%) received therapeutic anticoagulation and 237 (50.2%) received prophylactic dose. The demographic and baseline clinical characteristics were roughly similar between the groups. After adjustment for several confounders, in critical COVID-19 subgroup, therapeutic dose of anticoagulation was significantly associated with a higher inpatient mortality (AOR 2.27, 95% CI, 1.18-4.35, p = 0.013), whereas in severe COVID-19 subgroup, anticoagulation dosage was not associated with inpatient mortality (OR, 1.02, 95% CI, 0.45 - 2.33, p = 0.958). In severe COVID-19 patient group however, the incidence of thrombosis was slightly lower in the therapeutic group as compared with prophylactic group although the difference was not statistically significant (AOR 0.15, 95% CI, 0.02 - 1.20, p = 0.073). Although there were only six major bleeding events in this study, all these were recorded from patients in the therapeutic subgroup, making the difference statistically significant (p = 0.013). CONCLUSION: Although this study is limited by its observational design, our results are not consistent with current recommendations on anti-coagulation dose for hospitalized patients with COVID-19, necessitating the need for RCT in resource limited settings.

INTRODUCTION: In hospitalized COVID-19, neutrophil-to-lymphocyte ratio (NLR) and serum creatinine is sometimes measured under assumption they predict disease severity and mortality. We determined the potential value of NLR and serum creatinine as predictors of disease severity and mortality in COVID-19. METHODS: Prospective cohort study of COVID-19 patients admitted to premier COVID-19 treatment hospitals in Ethiopia. Predictive capability of biomarkers in progression and prognosis of COVID-19 was analyzed using receiver operating characteristics. Survival of COVID-19 patients with different biomarker levels was computed. Logistic regression assessed associations between disease severity and mortality on NLR and serum creatinine adjusted for odds ratio (AOR). RESULTS: The study enrolled 126 adults with severe (n = 68) or mild/moderate (n = 58) COVID-19, with median age 50 [interquartile range (IQR 20-86)]; 57.1% males. The NLR value was significantly higher in severe cases [6.68 (IQR 3.03-12.21)] compared to the mild/moderate [3.23 (IQR 2.09-5.39)], with the NLR value markedly associated with disease severity (p<0.001). Mortality was higher in severe cases [13 (19.1%)] compared to mild/moderate cases [2 (3.4%)] (p = 0.007). The NLR value was significantly higher in non-survivors [15.17 (IQR 5.13-22.5)] compared to survivors [4.26 (IQR 2.40-7.90)] (p = 0.002). Serum creatinine was significantly elevated in severe cases [34 (50%)] compared with mild/moderate [11 (19%)] (p<0.001). Disease severity [AOR 6.58, 95%CI (1.29-33.56), p = 0.023] and NLR [AOR 1.07, 95%CI (1.02-1.12), p = 0.004)] might be associated with death. NLR had a sensitivity and specificity of 69.1% and 60.3% as predictor of disease severity (cut-off >4.08), and 86.7% and 55.9% as prognostic marker of mortality (cut-off >4.63). CONCLUSION: In COVID-19, NLR is a biomarker with only modest accuracy for predicting disease severity and mortality. Still, patients with NLR >4.63 are more likely to die. Monitoring of this biomarker at the earliest stage of the disease may predict outcome. Additionally, high creatinine seems related to disease severity and mortality.

Data from much of Africa are still scarce on the clinical characteristics, outcomes of treatment, and factors associated with disease severity and mortality of COVID-19. A cross-sectional study was conducted at Eka Kotebe General Hospital, Ethiopia's first COVID-19 treatment center. All consecutive symptomatic SARS CoV-2 RT-PCR positive individuals, aged 18 and older, admitted to the hospital between March 13 and September 16, 2020, were included. Of the total 463 cases, 319 (68.9%) were male. The median age was 45 years (interquartile range 32-62). The most common three symptoms were cough (69%), shortness of breath (SOB; 44%), and fatigue (37%). Hypertension was the most prevalent comorbidity, followed by diabetes mellitus. The age groups 40 to 59 and ≥ 60 were more likely to have severe disease compared with those < 40 years of age (adjusted odds ratio [aOR] = 3.45, 95% confidence interval [CI]: 1.88-6.31 and aOR = 3.46, 95% CI: 1.91-6.90, respectively). Other factors associated with disease severity included the presence of any malignancy (aOR = 4.64, 95% CI: 1.32-16.33) and SOB (aOR = 3.83, 95% CI: 2.35-6.25). The age group ≥ 60 was significantly associated with greater in-hospital mortality compared with those < 40 years. In addition, the presence of any malignancy, SOB, and vomiting were associated with higher odds of mortality. In Ethiopia, most COVID-19 patients were male and presented with cough, SOB, and fatigue. Older age, any malignancy, and SOB were associated with disease severity; these factors, in addition to vomiting, also predicted mortality.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection results in a spectrum of clinical presentations. Evidence from Africa indicates that significantly less COVID-19 patients suffer from serious symptoms than in the industrialized world. We and others previously postulated a partial explanation for this phenomenon, being a different, more activated immune system due to parasite infections. Here, we aimed to test this hypothesis by investigating a potential correlation of co-infection with parasites with COVID-19 severity in an endemic area in Africa. Methods: Ethiopian COVID-19 patients were enrolled and screened for intestinal parasites, between July 2020 and March 2021. The primary outcome was the proportion of patients with severe COVID-19. Ordinal logistic regression models were used to estimate the association between parasite infection, and COVID-19 severity. Models were adjusted for sex, age, residence, education level, occupation, body mass index, and comorbidities. Findings: 751 SARS-CoV-2 infected patients were enrolled, of whom 284 (37.8%) had intestinal parasitic infection. Only 27/255 (10.6%) severe COVID-19 patients were co-infected with intestinal parasites, while 257/496 (51.8%) non-severe COVID-19 patients were parasite positive (p<0.0001). Patients co-infected with parasites had lower odds of developing severe COVID-19, with an adjusted odds ratio (aOR) of 0.23 (95% CI 0.17-0.30; p<0.0001) for all parasites, aOR 0.37 ([95% CI 0.26-0.51]; p<0.0001) for protozoa, and aOR 0.26 ([95% CI 0.19-0.35]; p<0.0001) for helminths. When stratified by species, co-infection with Entamoeba spp., Hymenolepis nana, Schistosoma mansoni, and Trichuris trichiura implied lower probability of developing severe COVID-19. There were 11 deaths (1.5%), and all were among patients without parasites (p = 0.009). Interpretation: Parasite co-infection is associated with a reduced risk of severe COVID-19 in African patients. Parasite-driven immunomodulatory responses may mute hyper-inflammation associated with severe COVID-19.
