[Hemodialysis treatment as a trigger cause of cryoglobulinemic purpura: a case report].

We describe the clinical case of a patient who developed mixed cryoglobulinemia syndrome after hemodialysis treatment with dialysate temperature lower than 36°C despite the negativization of the viral genome for HCV after eradication therapy.

Predictive factors of renal involvement or relapsing disease in children with Henoch-Schönlein purpura.

Predictive factors of renal involvement or relapsing disease in children with Henoch-Schönlein purpura (HSP) are poorly known. We examined clinical and laboratory variables concerning HSP evolution in children hospitalized in the last decade to predict the possibility of renal complications or relapse occurrence. Periodic clinical evaluations with urinalysis were performed for 6 +/- 3.
