Liver parasites: A global endemic and journey from infestation to intervention.

Parasites have coexisted with humans throughout history, forming either symbiotic relationships or causing significant morbidity and mortality. The liver is particularly vulnerable to parasitic infections, which can reside in, pass through, or be transported to the liver, leading to severe damage. This editorial explores various parasites that infect the liver, their clinical implications, and diagnostic considerations, as discussed in the article "Parasites of the liver: A global problem?". Parasites reach the liver primarily through oral ingestion, mucosal penetration, or the bloodstream, with some larvae even penetrating the skin. Hepatic parasites such as cestodes (Echinococcus), trematodes (Clonorchis, Opisthorchis), nematodes (Ascaris), and protozoa (Entamoeba histolytica) can also cause systemic infections like visceral leishmaniasis, malaria, cryptosporidiosis, and toxoplasmosis. Chronic infections like clonorchiasis and opisthorchiasis are linked to persistent hepatobiliary inflammation, potentially progressing to cholangiocarcinoma, a fatal bile duct cancer, particularly prevalent in Southeast Asia. The global nature of liver parasite infestations is alarming, with hundreds of millions affected worldwide. However, control over treatment quality remains suboptimal. Given the significant public health threat posed by these parasites, international medical organizations must prioritize improved diagnosis, treatment, and preventive measures. Strengthening educational efforts and enhancing healthcare provider training are critical steps toward mitigating the global impact of parasitic liver diseases.
