The effect of anti-coagulation dosage on the outcome of hospitalized COVID-19 patients in Ethiopia: a multi-center retrospective cohort study.

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.

Acute limb ischemia in COVID-19 patients despite therapeutic anticoagulation: Experience from Africa

Background Hypercoagulability is a common complication seen in COVID-19 infection. However, arterial thrombosis such as acute limb ischemia (ALI) is far less common. Data on the incidence and nature of arterial thromboembolic complications in patients with COVID-19 is limited, originating from a few case reports and case series. Data in the African continent is very scarce. Method This is a case series of 10 patients with COVID-19 who developed ALI while on treatment at Eka Kotebe General Hospital, Addis Ababa, Ethiopia. All patients with ALI and COVID-19 admitted between February 1, 2021, and December 31, 2021, were retrospectively identified and reviewed. COVID-19 was confirmed by RT-PCR and ALI was confirmed by Doppler ultrasound and/or computed tomography angiography in the presence of clinical suspicion. Results A total of 3098 patients were hospitalized with confirmed COVID-19 during the study period. In a series of 10 patients, 8 (80%) males with a median age of 53.5 years were included. All except one (10%) had one or more risk factors for ALI and one had a ‘possible' case of vaccine-induced thrombotic thrombocytopenia (VITT) associated with ALI. All were admitted with severe COVID-19 and most (80%) developed ALI during hospitalization (median of seven days from admission). The median duration between COVID-19 and ALI symptom onset was 14.5 days (IQR, 11–15). The majority (60%) were taking therapeutic anticoagulation at the time of ALI onset which is the standard of care for patients with severe disease. Five (50%) were successfully revascularized (median time of 3.5 days) and the rest underwent amputation. All survived and were discharged improved. Conclusion ALI can occur in the context of COVID-19 even while a patient is on therapeutic dose anticoagulation and in the absence of traditional risk factors. It is wise to be vigilant of this complication for timely intervention and better treatment outcomes.

Characteristics and outcomes of COVID-19 among people living with HIV at Eka Kotebe General Hospital, Addis Ababa, Ethiopia.

Introduction: Evidence on the interplay between HIV and COVID-19 is not entirely consistent. Methods: A retrospective cohort study was conducted on the medical records of patients who had a positive RT-PCR for COVID-19 and were admitted to Eka Kotebe General Hospital between March 2020 and October 2021. Results: A total of 427 patients, including 108 people living with HIV/AIDS (PLWH) and 319 people without HIV/AIDS, were included in the study. The median age of PLWH and people without HIV was 49.5 years (interquartile range 40-59 years) and 48 years (interquartile range 32-65 years), respectively. Of these patients, 258 (60.4%) were male and 169 (39.6%) were female. There were significant differences between PLWH and people without HIV in terms of age, tuberculosis, pregnancy, chronic liver disease, complications, shock, white blood cell count, and end outcome (alive or dead). There was no association between HIV status and the need for oxygen, intensive care unit admission, or disease severity. After adjusting for other variables, mortality was significantly higher among PLWH (adjusted odds ratio 2.25, 95% confidence interval 1.11-5.56; P = 0.023). Conclusions: PLWH with COVID-19 had a higher rate of in-hospital mortality than people without HIV, although no association was found between HIV status and the requirement for intensive care unit admission, mechanical ventilation, oxygen support, or the severity of the disease at the time of admission.

Clinical Characteristics and Treatment Outcomes of COVID-19 Patients at Eka Kotebe General Hospital, Addis Ababa, Ethiopia.

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.

Rhino-Orbital-Cerebral Mucormycosis in a Young Diabetic Patient with COVID-19 in Ethiopia: A Case Report.

Background: There has been a rise in secondary invasive fungal infections reported in COVID-19 patients globally. We report the first published case of COVID-19 associated rhino-orbital-cerebral mucormycosis in Africa in a newly diagnosed diabetic female who presented with diabetic ketoacidosis (DKA) and discuss the prevalence and risk factors of fungal co-infection with the clinical presentation, diagnosis, and management of mucormycosis in COVID-19. Case Presentation: A 39 years old female patient was admitted to ICU with a diagnosis of severe COVID-19 and newly diagnosed diabetes mellitus (DM) with DKA based on HgbA1c of 13.8% and positive RT-PCR. The patient was treated with dexamethasone in line with evidence in the RECOVERY trial and developed right facial and orbital swelling on her second hospital day. Brain MRI showed characteristic peri-sinonasal invasion with central nervous system (CNS) involvement, features suggestive of invasive fungal infection. Despite all medical and surgical treatments including liposomal amphotericin B and debridement, the patient died within 7 days of symptom onset. Conclusion: Clinicians should be aware of the potential for Rhino-Orbital-Cerebral Mucormycosis (ROCM) as a complication of COVID-19, especially in steroid taking diabetics who develop periorbital swelling and sinusitis. Timely diagnosis and multidisciplinary treatment are very critical.

Clinical Characteristics and Outcomes of Patients with COVID-19 Infection and Acute Ischemic Stroke at Eka Kotebe General Hospital in Addis Ababa, Ethiopia.

Background: Acute ischemic stroke has been reported to occur in a significantly higher number of COVID-19 patients as compared to healthy controls with variable proposed pathophysiologic mechanisms. To our knowledge, sufficient data regarding this subject is lacking in Ethiopia and the African continent at large. In this case series, we report the clinical characteristics and management of 5 cases with COVID-19 infection and acute ischemic stroke to shed light on the diagnostic and therapeutic challenges in resource-limited setups. Methods: This is a case series including data collected from the medical records of 5 participants with confirmed RT-PCR positive COVID-19 infection and radiologically confirmed acute ischemic stroke, admitted at Eka Kotebe General Hospital Intensive Care Unit (ICU) in Addis Ababa, Ethiopia from June 10, 2020, to November 04, 2020. Results: Cryptogenic stroke was documented in 4/5 participants included in this series with the most common vascular risk factors identified for stroke being hypertension and diabetes mellitus. The median time from onset of COVID-19 symptoms to the identification of stroke was 07 days. Two fifth of the participants in this series died during their ICU admission with the immediate cause of deaths reported to be related to the severe COVID-19 infection but not stroke. Conclusion: Cryptogenic stroke was documented in 4/5 patients in this series despite the presence of vascular risk factors for other stroke subtypes. The overall prevalence, subtypes, and outcomes of stroke in COVID-19 patients in Ethiopia and the African continent as a whole needs additional research to elucidate the local burden of the disease and define the predominant pathophysiologic mechanisms for stroke in COVID-19 in the region.

Clinical outcome of bronchoalveolar lavaged COVID ARDS patients.

Introduction: One of the biggest pandemics of the human race, Coronavirus disease, has reported mortality rates as high as 80% for critically ill patients. It has killed more than 3.9 million people worldwide with no strongly proven management options to decrease its mortality. One of the options gaining interest is fiberoptic bronchoscopy and bronchoalveolar lavage. Our study was conducted to assess the clinical outcome of intubated Coronavirus disease patients that had a fiberoptic bronchoscopy and bronchoalveolar lavage done. Methods and materials: A consecutive prospective case series of intubated patients with critical Coronavirus disease pneumonia were conducted at Bethzatha general hospital from April 20, 2021, to July 30, 2021 GC. Results: Five patients with a median age of 55 years were included in the study. The median APACHE II, SAPS II, and SOFA scores on admission were 13, 37, and 4 respectively. The difference in the mean values of; positive end-expiratory pressure, static compliance, plateau pressure, fractional inspired oxygen, and arterial oxygen tension to fractional inspired oxygen ratio between the time of intubation and the last fiberoptic bronchoscopy and bronchoalveolar lavage were 4.4 cmH2O, 11 ml/cmH2O, 6.2 cmH2O, 45%, and 76 mmHg. All patients were liberated from mechanical ventilation. Conclusion: - There was a numerically and clinically significant improvement in lung mechanics and oxygenation leading to a 100% ventilator liberation rate. Fiberoptic bronchoscopy and bronchoalveolar lavage in Coronavirus disease patients can improve lung mechanics, oxygenation, and rates of extubation.
