Dr. Randhawa is one of five pathologists in the Division of Transplant Pathology. He has special expertise in the evaluation of native and kidney transplant biopsies. Difficult consult cases in this area are regularly referred to him for his opinion. He is the Course Director of a weekly multidisciplinary clinical conference on kidney allograft pathology. He is an established investigator with a long history of successful funding in the area of polyomavirus infections after kidney transplantation. He teaches medical students, residents and fellows and is regular speaker in national and international meetings focusing on renal transplantation.

Clinical Expertise

Pathologic evaluation of native, donor and allograft liver, kidney and heart, allograft small intestine and pancreas biopsies and surgical resections. He is lead patholgist for the University of Pittsburgh Kidney Transplantation Program with unmatched experience in the light microscopic, immunofluorescence and ultratructural evaluation of kidney biopsies.

Research Interests

The clinical profile of patients with BK virus infection in the renal allograft is being defined. Next generation sequencing of the T-cell receptor is being used to develop tests that can distinguish anti-viral and anti-graft immune responses. DNA sequencing of viral strains is being used to define mutations and genomic rearrangements, which may be relevant to the pathogenesis of an extremely refractory interstitial nephritis seen in these individuals. Quantitative PCR assays have been developed to measure viral load in biopsy samples and body fluids to better manage the immunosuppression levels in these patients. The interplay between host and viral immune factors in this disease is being investigated by cellular immunology, miRNA and RNAseq techniques. Drugs with antiviral activity are being screened in an in-vitro culture model for possible future use in the clinical arena. Efforts are underway to develop a mouse model of polyomavirus nephropathy that better mimics human disease than currently available models.
