Abstract:
Leishmaniasis, malaria, toxoplasmosis, and acanthamoebiasis are protozoan parasitic infections. They remain important contributors to the development of kidney disease, which is associated with increased patients' morbidity and mortality. Kidney injury mechanisms are not fully understood in protozoan parasitic diseases, bringing major difficulties to specific therapeutic interventions. The aim of this review is to present the biochemical and molecular mechanisms in kidneys infected with Leishmania spp., Plasmodium spp., Toxoplasma gondii, and Acanthamoeba spp. We present available mechanisms of an immune response, oxidative stress, apoptosis process, hypoxia, biomarkers of renal injury in the serum or urine, and the histopathological changes of kidneys infected with the selected parasites. Pathomechanisms of Leishmania spp. and Plasmodium spp. infections have been deeply investigated, while Toxoplasma gondii and Acanthamoeba spp. infections in the kidneys are not well known yet. Deeper knowledge of kidney involvement in leishmaniasis and malaria by presenting their mechanisms provides insight into how to create novel and effective treatments. Additionally, the presented work shows gaps in the pathophysiology of renal toxoplasmosis and acanthamoebiasis, which need further research.
Insights
Protozoan parasitic infections like leishmaniasis and malaria significantly impact kidney health, causing injury through complex mechanisms. Further research into renal toxoplasmosis and acanthamoebiasis is crucial for developing effective treatments.
Area of Science:
- * Parasitology
- * Nephrology
- * Immunology
Background:
- * Protozoan parasitic infections, including leishmaniasis, malaria, toxoplasmosis, and acanthamoebiasis, are linked to kidney disease, increasing patient morbidity and mortality.
- * The precise mechanisms of kidney injury in these parasitic diseases are not fully understood, hindering targeted therapeutic strategies.
Purpose of the Study:
- * To review the biochemical and molecular mechanisms of kidney injury caused by *Leishmania* spp., *Plasmodium* spp., *Toxoplasma gondii*, and *Acanthamoeba* spp.
- * To elucidate the roles of immune response, oxidative stress, apoptosis, hypoxia, and renal injury biomarkers in parasitic kidney disease.
Main Methods:
- * Comprehensive literature review of existing studies on protozoan parasitic infections and kidney involvement.
- * Analysis of biochemical, molecular, and histopathological data related to renal pathogenesis.
Main Results:
- * Mechanisms of kidney injury in leishmaniasis and malaria are relatively well-investigated.
- * Pathophysiology of renal toxoplasmosis and acanthamoebiasis remains less understood, highlighting research gaps.
- * Identified key factors: immune response, oxidative stress, apoptosis, hypoxia, and specific biomarkers.
Conclusions:
- * Understanding the detailed mechanisms of kidney involvement in leishmaniasis and malaria can guide the development of novel treatments.
- * Further investigation into the renal pathophysiology of toxoplasmosis and acanthamoebiasis is essential for comprehensive patient care and disease management.
