Malaria Epidemiology and COVID-19 Pandemic: Are They Interrelated?

Coronavirus disease 2019 (COVID-19) is a systemic disease, impacting multiple organs in the human body. But COVID-19 also impacts other diseases of relevance to public and planetary health. To understand and respond to the COVID-19 pandemic, we need an intersectional conceptual lens and systems thinking. For example, the strain on health care systems due to COVID-19 has adversely impacted global malaria elimination programs. With many epidemiological, clinical, and biological parallels documented, we examined in this study the scenario of malaria and COVID-19 syndemic in India. The disruptive influence of COVID-19 on the National Framework for Malaria Elimination (NFME), impact of unintended chemoprophylaxis, population genetic influences, and the shifting patterns of epidemiology are compared. Importantly, a time series analysis forecasted the burden of malaria increasing in the upcoming years. Although reported malaria cases showed a decline in 2020 compared to the previous years, an increase in cases was documented in 2021, with nine states reporting an increase up to July 2021. Pandemics often cause crosscutting disruptions in health care. Reshaping the priorities of the malaria elimination program and a diligent implementation of the priorities in the NFME would, therefore, be well-advised: (1) vector control, (2) antimalarial therapy recommendations, (3) monitoring drug resistance, (4) prevention of the spread of asymptomatic disease-causing low-density transmission, and (5) large-scale testing measures. In conclusion, the findings from the present study inform future comparative studies in other world regions to better understand the broader, systemic, temporal, and spatial impacts of the COVID-19 pandemic on existing and future diseases across public health systems and services.

Alpha-lipoic acid may protect patients with diabetes against COVID-19 infection

COVID-19 pandemic is spreading rapidly worldwide, and drug selection can affect the morbidity and mortality of the disease positively or negatively. Alpha-lipoic acid (ALA) is a potent antioxidant and reduces oxidative stress and inhibits activation of nuclear factor-kappa B (NF-kB). ALA reduces ADAM17 activity and ACE2 upregulation. ALA is known to have antiviral effects against some viruses. ALA may show antiviral effect by reducing NF-kB activation and alleviating redox reactions. ALA increases the intracellular glutathione strengthens the human host defense. ALA activates ATP dependent K+ channels (Na+, K+-ATPase). Increased K+ in the cell raises the intracellular pH. As the intracellular pH increases, the entry of the virus into the cell decreases. ALA can increase human host defense against SARS-CoV-2 by increasing intracellular pH. ALA treatment increases antioxidant levels and reduces oxidative stress. Thus, ALA may strengthen the human host defense against SARS-CoV-2 and can play a vital role in the treatment of patients with critically ill COVID-19. It can prevent cell damage by decreasing lactate production in patients with COVID-19. Using ALA with insulin in patients with diabetes can show a synergistic effect against SARS-CoV-2. We think ALA treatment will be beneficial against COVID-19 in patients with diabetes.
