Background: The aim of this case study was to explore the possible link between viral infections and collapsing focal segmental glomerulosclerosis (cFSGS) in patients who underwent kidney transplantation.
Methods: This case study included 3 case reports of patients who underwent kidney transplantation. The case reports were presented clinically and pathohistologically with cFsGS as a possible consequence of viral infections.
Results: The first patient developed cFSGS after polymerase chain reaction for SARS-CoV2 was positive twice. He gradually developed terminal stage chronic kidney disease. The second patient developed cFSGS with high range proteinuria after cytomegalovirus infection, which has been treated with 3 lines of antiviral medicaments. The third patient developed cFSGS as a possible consequence of hepatitis B virus infection.
Conclusions: This case study highlighted the importance of viral etiology in the pathway of cFSGS. Pathogenic links between viral infections and concomitant glomerulopathies are challenging, especially in immunocompromised transplanted patients.
