Are therapeutic stem cells justified in bilateral multicystic kidney disease? A review of literature with insights into the embryology.
Aim was to describe the challenges faced in the management of bilateral multicystic kidney disease (MCKD). A case of antenatally detected bilateral polycystic disease was referred at 28 weeks of gestation. The patient was advised to continue pregnancy till term and be in regular follow-up. Postnatally, the male baby passed urine in normal stream and was diagnosed as bilateral multicystic kidney disease on ultrasonography. He developed symptoms of renal failure. The baby was operated with right pyeloplasty and left pyelostomy, as the left ureter was atretic. The histopathology was consistent with bilateral multicystic kidney disease. Postoperatively, the baby was stable with intermittent episodes of metabolic acidosis that were managed medically and with peritoneal dialysis. Autologous stem cells were injected at the age of 1 year into the aorta at the level of the renal arteries clamping the aorta below. Repeat biopsy at time of stem cell injection showed 5/10 glomeruli showing global sclerosis on right side and 5/15 glomeruli showing global sclerosis on left side. The only improvement seen was in decreased doses of medicines to keep the child metabolically stable. The baby kept struggling but succumbed at the age of 17 months and 15 days. Post mortem bilateral renal biopsies demonstrated presence of primitive renal tubules and blastemal cells that were not demonstrated earlier. Survival for few months in bilateral multicystic kidney disease is thus possible with adequate treatment, the novel use of stem cells in these cases may prove beneficial in future though it is too early to comment further.
