The potential influence of pre-existing parasitic infections on COVID-19 morbidity PLOSNTDs disease infection parasite COVID19 coronavirus covid morbidity
By Dr. Sanchari Sinha Dutta, Ph.D.Oct 13 2022Reviewed by Danielle Ellis, B.Sc. A study recently published in PLOS Neglected Tropical Diseases has explored the association between the prevalence of pre-existing parasitic diseases and outcomes of coronavirus disease 2019 at the national level.
Several hypotheses have been put forward to explain this noticeable difference in COVID-19 outcomes between countries. Several causative factors have been identified, including socio-demographic and geographical factors, the prevalence of comorbidities, climatic conditions, as well as the possibility of underreporting.
Of various human-infecting parasites, only Schistosoma spp., soil-transmitted helminthiases, and Plasmodium spp. were considered in the study. Regarding socioeconomic factors, country-level healthcare infrastructure, income, and overall standard of living were considered. Moreover, the country-level population density, population density in urban regions, and average surface temperature were considered geographic factors.
The assessment of the relationship between one independent and one dependent variable revealed that countries with a high prevalence of parasitic diseases have a lower incidence of COVID-19.

Elevated vascular transformation blood biomarkers in Long-COVID indicate angiogenesis as a key pathophysiological mechanism - Molecular MedicineBackground Long-COVID is characterized by prolonged, diffuse symptoms months after acute COVID-19. Accurate diagnosis and targeted therapies for Long-COVID are lacking. We investigated vascular transformation biomarkers in Long-COVID patients. Methods A case–control study utilizing Long-COVID patients, one to six months (median 98.5 days) post-infection, with multiplex immunoassay measurement of sixteen blood biomarkers of vascular transformation, including ANG-1, P-SEL, MMP-1, VE-Cad, Syn-1, Endoglin, PECAM-1, VEGF-A, ICAM-1, VLA-4, E-SEL, thrombomodulin, VEGF-R2, VEGF-R3, VCAM-1 and VEGF-D. Results Fourteen vasculature transformation blood biomarkers were significantly elevated in Long-COVID outpatients, versus acutely ill COVID-19 inpatients and healthy controls subjects (P | 0.05). A unique two biomarker profile consisting of ANG-1/P-SEL was developed with machine learning, providing a classification accuracy for Long-COVID status of 96%. Individually, ANG-1 and P-SEL had excellent sensitivity and specificity for Long-COVID status (AUC = 1.00, P | 0.0001; validated in a secondary cohort). Specific to Long-COVID, ANG-1 levels were associated with female sex and a lack of disease interventions at follow-up (P | 0.05). Conclusions Long-COVID patients suffer prolonged, diffuse symptoms and poorer health. Vascular transformation blood biomarkers were significantly elevated in Long-COVID, with angiogenesis markers (ANG-1/P-SEL) providing classification accuracy of 96%. Vascular transformation blood biomarkers hold potential for diagnostics, and modulators of angiogenesis may have therapeutic efficacy.
