Transplantation rénale chez un patient hémophile A

Renal transplant in a patient of severe hemophilia

Hemophilia is a rare disorder that is difficult to diagnose and manage. The prevalence of end-stage renal disease is increasing in hemophilic patients because of improved life expectancy. Renal transplant surgery in such patients is often complicated by adverse hematological events such as bleeding and intravesical thrombosis, both with a risk of renal allograft rejection. We report a case of a 46-year-old hemophilia A patient on hemodialysis who underwent renal transplant and show that although challenging, renal transplant in hemophilic patients is possible.

[Clinical management of patients with hemophilia A in nephrology: Diagnostic and therapeutic challenges illustrated by the cases of 2 patients]

Hemophilia A is an X-linked genetic hemorrhagic disorder characterized by a factor VIII deficiency. The availability of secured substitution products has led to a dramatic improvement of life expectancy in hemophiliac patients. Nowadays, adult hemophiliac patients may develop Chronic Kidney Disease (CKD) resulting from age-related comorbidities (hypertension, obesity, diabetes). In addition, the high prevalence of viral infections in this population exposes patients to an increased risk of CKD. The risk of hemorrhage in hemophiliac patients is a challenge for their clinical management, both for diagnostic procedures (kidney biopsy in particular) and for renal replacement therapy (dialysis or renal transplantation) when it is needed. This work provides an update of the literature data concerning the management of hemophiliac patients in nephrology, illustrated by the cases of two patients.
