Bridging Gaps in Long COVID Therapy: A Mini Review.

Abstract

Introduction: Long COVID-19 (LC) is a condition that follows SARS-CoV- -2, an acute infection defined by persistent fatigue, dyspnea, and impaired cognitive function. LC presents a complex array that imposes ongoing challenges on global health, patients' quality of life, and functional capacity. Many inconsistencies surround its pathophysiology, diagnosis, prevention, and treatment. This review aims to cover missed gaps in LC with a special focus on therapeutic strategies concerning non-pharmacological, pharmacological, experimental, and innovative approaches for better patient management and outcomes, as well as to evaluate their effectiveness and guide future research.

Methods: An online search was conducted using five digital repositories: PubMed, Scopus, Google Scholar, Web of Science, and the Cochrane Library. A combination of keywords associated with LC therapy was employed: "long COVID, "pharmacological options," "non-pharmacological options," "innovative strategies," "experimental", and" quality of life (QOL)." Relevant data were extracted and synthesized to categorize therapeutic approaches into subtypes. A critical analysis was conducted on their mechanism of action, indication, outcome, and limitations.

Results: The pooled prevalence of LC was 42%, and the symptom duration ranged from 3 months to 2 years. The most important risk factors for LC were female sex, unvaccinated status, and cases with co-morbidities. Diagnosis of LC was challenging due to a lack of diagnostic standardization and reliable biomarkers.

Discussion: Non-pharmacological strategies were employed first, showing diverse efficacies; however, the reported literature was hindered by small sampling. Pharmacological agents show promising results but need further validation. Experimental and innovative strategies need longer studies and validations.

Conclusion: LC has imposed a significant burden on community health, necessitating the appropriate allocation of health resources and community support. Preventive and therapeutic interventions show promise, but the variability in patient response underscores the need for personalized approaches and more well-designed trials. Collaborative research and multi-disciplinary teams are needed to mitigate the long-term effects of LC and improve patient outcomes.
