The UC Davis Department of Pediatrics has the only pediatric nephrology, renal transplant and pediatric home peritoneal dialysis program in the Sacramento region. The Nephrology Clinic cares for children on dialysis and those with chronic kidney disease (CKD), renal transplants, hypertension, urinary tract infections, glomerulonephritis, stones, renal tubular acidosis, systemic lupus erythematosus (and other autoimmune disease) and hydronephrosis (and other prenatally diagnosed renal anomalies). Diagnostic and therapeutic services performed by the section include:
- peritoneal dialysis
- continuous dialysis
- ambulatory blood pressure monitoring
- renal biopsy
- renal transplantation
Our nephrologists are widely sought for their consultation services by health care professionals in the Northern California, Southern Oregon, Northern Nevada, and the Greater Sacramento area. We attribute our success to our team approach in which transplant surgeons, urologists, social workers, psychiatrists, psychologists, dietitians, pharmacists and clinical nurses participate in the care of our patients.
Members of our team are recognized nationally for advances in treatment and research studies benefiting patients who have CKD and those with renal transplants. The section is also very active in providing medical education to all levels of learners (preclinical and clinical medical students, residents, faculty and nursing staff) using a variety of teaching techniques. Members of our section are also engaged in clinical trials, multi-center national research projects and quality improvement collaboratives. We are active in research related to medical education, hypertension, glomerulonephritis, hypercalciuria/stone disease, and ways to improve graft survival and quality of life of children with renal transplantation by using newer medications and treatment approaches. Recently completed and ongoing studies are looking at:
- Effectiveness of health care providers in recognizing hypertension in high-risk populations such as children with CKD, diabetes, and obesity
- Benefits and challenges associated with novel steroid-free immunosuppressive regimens in children after renal transplants
- Correlation between microalbuminuria and serum inflammatory markers in adolescents of different ethnic backgrounds and of varying BMI
- Diagnostic tests for hypercalciuria
- Development of valid tools to measure resident performance as teachers and clinical role models
- Clinical trials for children affected by focal segmental glomerulonephritis and electrolyte abnormalities associated with chronic kidney disease
