Hypertension is commonly associated with Wilms tumor, but hypertension secondary to renin-secreting Wilms tumor is uncommon. We present an infant with severe hypertension and renin hypersecretion, which was resistant to multiple antihypertensive agents. Blood pressure was eventually controlled with a combination of captopril and losartan.

Familial Mediterranean fever (FMF) is an autosomal recessive disorder characterized by recurrent and self-limited attacks of serosal inflammation with abdominal pain, chest pain, and arthritis usually accompanied by fever. Different vasculitides such as polyarteritis nodosa (PAN) and Henoch-Schönlein syndrome (HSS) may be associated with FMF. ⋯ Neither sister developed amyloidosis until the age of 30 years. This observation suggests that early events in the pathogenesis of PAN and HSS are generally quite similar.

Acute renal failure (ARF) with fluid overload (FO) occurs often in stem cell transplant (SCT) recipients. We have previously demonstrated that an increased percentage of FO prior to the initiation of continuous renal replacement therapy (CRRT) is associated with mortality in children with ARF. Based on these data, we devised a protocol for the prevention of FO in SCT patients with ARF. ⋯ The use of one or more pressors, the presence of graft-versus-host disease, and septic shock were not correlated with survival. Our data demonstrate that maintenance of euvolemia ( <10% FO) is critical but not sufficient for survival in SCT patients with ARF, as all non-euvolemic patients died. We suggest that aggressive use of diuretics and early initiation of RRT to prevent worsening of FO may improve the survival of SCT patients.
