Immunological underpinnings of infection, reinfection and co-infection and their associated co-morbidities.

Parasitology 2021 Apr 12:1-10. Epub 2021 Apr 12.

Department of Parasitology, Federal University of Minas Gerais, Belo Horizonte, Minas Gerais, Brazil.

Human ascariasis is the most common and prevalent neglected tropical disease and is estimated that ~819 million people are infected around the globe, accounting for 0.861 million years of disability-adjusted life years in 2017. Even with the existence of highly effective drugs, the constant presence of infective parasite eggs in the environment contribute to a high reinfection rate after treatment. Read More

Gastroenterology and Hepatology Unit, Division of Internal Medicine, Faculty of Medicine, Prince of Songkla University, Hatyai, Songkhla, Thailand

Acute cholangitis is a condition of bacterial infection following hepatobiliary tract obstruction, which signifies poor prognosis unless adequately drained. The most common cause of bile duct obstruction is choledocholithiasis, in contrast to parasitic infestation, a rare entity causing acute cholangitis nowadays. Therefore, we reported the case of a 68-year-old Thai man who presented with acute fever, intense right upper quadrant abdominal pain and jaundice for 2 days. Read More

Helminth-derived cystatins: the immunomodulatory properties of an cystatin.

Parasitology 2021 Feb 10:1-13. Epub 2021 Feb 10.

Institute for Immunological Research, University of Cartagena, Cartagena de Indias, Colombia.

Helminth infections such as ascariasis elicit a type 2 immune response resembling that involved in allergic inflammation, but differing to allergy, they are also accompanied with strong immunomodulation. This has stimulated an increasing number of investigations, not only to better understand the mechanisms of allergy and helminth immunity but to find parasite-derived anti-inflammatory products that could improve the current treatments of chronic non-communicable inflammatory diseases such as asthma. A great number of helminth-derived immunomodulators have been discovered and some of them extensively analysed, showing their potential use as anti-inflammatory drugs in clinical settings. Read More
