Profiles of Independent-Comorbidity Groups in Senior COVID-19 Patients Reveal Low Fatality Associated with Standard Care and Low-Dose Hydroxychloroquine over Antivirals.

Introduction: The lack of feasible therapies and comorbidities aggravate the COVID-19 case-fatality rate (CFR). However, reports examining CFR associations with diabetes, concomitant cardiovascular diseases, chronic kidney disease, and chronic liver disease (CLD) are limited. More studies assessing hydroxychloroquine (Hcq) and antivirals are needed. Purpose: To examine associations of COVID-19 CFR in comorbid patient groups each with single comorbidities and after treatment with Hcq, favipiravir, and dexamethasone (Dex), either alone or in combination versus standard care. Methods: Using statistical analysis, we descriptively determined these associations among 750 COVID-19 patient groups during the last quarter of 2021. Results: A diabetes comorbidity (40%, n=299) showed twice the fatality (CFR 14%) of the others (CFR 7%; P=0.001). Hypertension (Htn) was the second-commonest comorbidity (29.5%, n=221), with similar CFR to diabetes (15% and 7% for Htn and non-Htn, respectively), but with higher significance (P=0.0006167). Although only 4% (n=30) heart failure (HF) was reported, the CFR (40%) was much higher than in those without it (8%). A similar rate (4%) for chronic kidney disease was reported, with CFRs of 33% and 9% among those with and without it, respectively (P=0.00048). Ischemic heart disease was 11% (n=74), followed by chronic liver disease (0.4%) and history of smoking (1%); however, these were not significant due to the sample sizes. Treatment indicated standard care and Hcq alone or in combination were superior (CFR of 4% and 0.5%, respectively) compared to favipiravir (25%) or Dex (38.5%) independently or in combination (35.4%). Furthermore, Hcq performed well (CFR 9%) when combined with Dex (9%; P=4.28-26). Conclusion: The dominance of diabetes and other comorbidities with significant association with CFR implied existence of a common virulence mechanism. The superiority of low-dose Hcq and standard care over antivirals warrants further studies.

General Measures for the Treatment of Pulmonary Arterial Hypertension According to the New Guidelines

Treatment of PAH involves a multidisciplinary approach that includes general measures. Supervised exercise and rehabilitation, diuretics, vaccination against influenza, pneumococcus and SARS-CoV-2, iron administration for iron deficiency anaemia, and in-flight O (2) administration for low oxygen saturation are now clearly recommended. No general recommendation can be made for the use of anticoagulation, the choice of an anaesthetic procedure, the use of cardiovascular drugs or the administration of long-term oxygen administration. Treatment choices should be based on individual decisions involving a PH expert centre. The management of women of childbearing potential with PAH is complex and requires comprehensive counselling, psychological support and close medical care regarding risks of and alternatives to pregnancy, contraception, as well as multidisciplinary support for existing or desired pregnancy and abortion.

A Novel Case Report of Severe Aplastic Anemia with COVID Infection.

Aplastic anemia is a rare disease of the hematopoietic system. Although some viral agents have been implicated, the association between COVID-19 and aplastic anemia is unclear. In this way, several cases of aplastic anemia have been reported following infection with COVID-19. Importantly, we reported a 16-year-old girl with severe aplastic anemia with no history of disease following an Omicron infection who did not respond well to treatment despite supportive treatment and immunosuppression.

Clinical features of elderly patients with COVID-19 in Wuhan, China.

BACKGROUND: Elderly patients with coronavirus disease 2019 (COVID-19) who have comorbidities, frailty or profound disabilities experience poor outcomes. We analyzed the clinical characteristics of elderly patients from Wuhan who had COVID-19 during the early stages of the pandemic. AIM: To identify factors affecting the early mortality of elderly patients with COVID-19. METHODS: The records of 234 patients who were 65-years-old or more and were hospitalized in Wuhan Huoshenshan Hospital from February 4 to March 4, 2020 were reviewed. All patients had confirmed COVID-19 and the final date of follow-up was April 4, 2020. RESULTS: There were 163 cases of mild disease (69.66%), 39 cases of severe disease (16.67%) and 32 cases of critical disease (13.68%). Twenty-nine patients died within 1 mo (12.40%), all of whom had critical disease. Surviving patients and deceased patients had no significant differences in age or chronic diseases. Overall, the most common symptoms were fever (65.4%), dry cough (57.3%), fatigue (47.4%) and shortness of breath (41%). The deceased patients had higher levels of multiple disease markers (C-reactive protein, D-dimer, lactate dehydrogenase, alanine amino transferase, aspartate aminotransferase, creatinine kinase and creatinine kinase-MB) and higher incidences of lymphocytopenia and hypoproteinemia. CONCLUSION: This single-center study of elderly patients from Wuhan, China who were hospitalized with COVID-19 indicated that age and chronic diseases were not associated with mortality. Hypertension, diabetes and cardiovascular disease were the most common comorbidities and the most common symptoms were fever, dry cough, fatigue and shortness of breath. Lymphocytopenia, increased levels of D-dimer and other markers indicative of damage to the heart, kidneys or liver were associated with an increased risk of death.

Efficacy and sustainability of natural products in COVID-19 treatment development: opportunities and challenges in using agro-industrial waste from Citrus and apple.

Natural products have been used in the treatment of illnesses throughout the history of humankind. Exploitation of bioactive compounds from natural sources can aid in the discovery of new drugs, provide the scaffold of new medicines. In the face of challenging diseases, such as the COVID-19 pandemic, for which there was no effective treatment, nature could offer insights as to novel therapeutic options for control measures. However, the environmental impact and supply chain of bioactive production must be carefully evaluated to ensure the detrimental effects will not outweigh the potential benefits gained. History has already proven that highly bioactive compounds can be rare and not suitable for medicinal exploitation; therefore, the sustainability must be accessed before expensive, time-demanding, and large trials can be initialized. A sustainable option to readily produce a phytotherapy with minimal environmental stress is the use of agro-industry wastes, a by-product produced in high quantities. In this review we evaluate the sustainability issues associated with the production of phytotherapy as a readily available tool for pandemic control.

Possibility of magnesium supplementation for supportive treatment in patients with COVID-19.

Magnesium as an enzymatic activator is essential for various physiological functions such as cell cycle, metabolic regulation, muscle contraction, and vasomotor tone. A growing body of evidence supports that magnesium supplementation (mainly magnesium sulfate and magnesium oxide) prevents or treats various types of disorders or diseases related to respiratory system, reproductive system, nervous system, digestive system, and cardiovascular system as well as kidney injury, diabetes and cancer. The ongoing pandemic coronavirus disease 19 (COVID-19) characterized by respiratory tract symptoms with different degrees of important organ and tissue damages has attracted global attention. Particularly, effective drugs are still lacking in the COVID-19 therapy. In this review, we find and summarize the effectiveness of magnesium supplementation on the disorders or diseases, and provide a reference to the possibility of magnesium supplementation for supportive treatment in patients with COVID-19.

Symptomatic and optimal supportive care of critical COVID-19: A case report and literature review.

BACKGROUND: Coronavirus disease 2019 (COVID-19) severity is classified as asymptomatic, mild, moderate, severe, and critical. Mild cases account for a large percentage of cases in the epidemic and typically exhibit a favorable prognosis. However, a 49%-67% mortality is noted in critical cases. No COVID-19-specific drug has been reported to date, and symptomatic and optimal supportive care, including oxygenation, anti-coinfection treatments, and ventilation, represent the mainstay of treatment for this disease, especially in critical patients. CASE SUMMARY: In the above-mentioned context, we share our experience with the treatment of one critical COVID-19 case and review the relevant literature. CONCLUSION: Timely tracheal intubation, reasonable mechanical ventilation support, appropriate anti-infection treatment, and early anticoagulation and immunity support are key factors in the successful treatment of this case.

Clinical characteristics, treatment regimen and duration of hospitalization among COVID-19 patients in Ghana: a retrospective cohort study.

INTRODUCTION: COVID-19 is a global pandemic seen in modern times. The clinical characteristics, treatment regimen and duration of hospitalization of COVID-19 patients remain unclear in Ghana. METHODS: we retrospectively reviewed the secondary data of 307 discharged COVID-19 patients to characterize their demographics, clinical symptoms, treatment regimen given and duration of hospitalization. RESULTS: the mean age and temperature of the patients were 37.9 years and 36.3°C, respectively. The majority (85.7%) of the cases reviewed were asymptomatic; for those presenting with symptoms, the main ones were cough (50%), fever (29.6%), headache (27.3%), and sore throat (22.7%). Comorbidities were present in 25.1% of the patients; the popularly reported comorbidities were hypertension (71.4%), asthma (7.8%) and diabetes (6.5%). The average duration of hospitalization was 13.8 days, and the duration of hospitalization for patients managed with azithromycin + chloroquine (AZ+CQ) was 10.4 days, followed closely by those managed with hydroxychloroquine (HCQ) only, 11.0 days. There was longer duration of hospitalization among patients who received AZ only compared to patients receiving AZ + CQ (3.24 ± 1.10 days, p=0.037; 95% CI 0.11, 6.37). Linear regression analysis showed that the duration of hospitalization for patients who received AZ only was 2.7 days, which was higher than that of patients who received AZ+CQ and HCQ only (95% CI 0.44, 4.93; p=0.019). CONCLUSION: in this cohort of COVID-19 patients, the common symptoms were cough, fever, headache, and sore throat. The use of AZ+CQ or HCQ only as a therapy for managing COVID-19 patients shortened the duration of hospitalization.
