The present review summarized the effect of parasitic infections as the risk factors or protective agents in the COVID-19 pandemic. Parasites could proficiently modulate immune responses. Thus, parasitic infections could have a different impact on the incidence and clinical severity of COVID-19 in different regions of the world. Also, restoring programs to prevent, treat, and control NIDs, in particular helminths, could help in reducing the incidence and mortality of COVID-19 in endemic areas and help to increase vaccination effectiveness. Changes in the gut microbiome associated with helminth infection may have systemic immunomodulatory effects toward suppressing host immune responses, reducing vaccine efficacy and increasing the severity of other infectious diseases. The cytokine storm observed in severe cases of COVID-19 is characterized by a predominance of proinflammatory cytokines, such as IL-6. However, it is possible that helminth infection could change the outcome of infection by modifying the Th2 response to limit the inflammatory component; this would be particularly apparent in areas endemic for helminthic infections, which suggests a possible protective effect against COVID-19. Because parasitic infections affect more than 2 billion people throughout the world, their impact on COVID-19-associated effects on public health could be considerable. Further studies with larger sample sizes would be needed to explore the possible role of neglected parasitic infections in the COVID-19 pandemic.</p>","PeriodicalId":7987,"journal":{"name":"Annals of parasitology","volume":"68 4","pages":"667-672"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10353788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Type-2 diabetics are among the population categories most vulnerable to a variety of infections, including IPIs. Therefore, this study determined the prevalence and risk factors associated with IPIs among Yemeni type-2 diabetics in Sana'a city. This hospital-based, cross-sectional study recruited 389 type-2 diabetics seeking healthcare in Sana'a from December 2019 to February 2020. Sociodemographic data and risk factors were collected from interviewed participants using a structured questionnaire. Stool samples were collected and examined for parasites using standard techniques. The association of sociodemographic characteristics and risk factors with IPIs was tested using univariate analysis, and a multivariable logistic regression model was developed to identify the independent predictors of IPIs at a significance level of <0.05. The overall prevalence of IPIs among diabetics was 38.6%. Entamoeba histolytica/dispar (30.3%) was the most frequent parasite, followed by Cryptosporidium species (8.2%). The significant independent predictors of IPIs were duration of diabetes mellitus > 10 years (AOR = 1.6; 95% CI: 1.10-2.47, P = 0.029), eating unwashed vegetables/fruits (AOR = 3.2; 95% CI: 1.44-6.92, P = 0.004) and not practicing handwashing before meals (AOR = 2.4; 95% CI: 1.10-5.48, P = 0.035). Over one-third of type-2 diabetics seeking healthcare in Sana'a city are infected with one or more IPIs, predominantly with E. histolytica/dispar, followed by Cryptosporidium species. Such infections cannot be predicted from the sociodemographic characteristics of diabetics. Nevertheless, prolonged duration of diabetes mellitus, eating unwashed vegetables/fruits and not practicing handwashing before meals are independent predictors of IPIs among type-2 diabetics.

This was investigated and proven using monoclonal antibody, western blot analysis and immunofluorescence (IFA) technique. It has also been used in various studies regarding the biological control of malaria by killing Anopheles mosquito larvae.
