Peripheral nerve injuries in haemophilia

Neurological Complications Associated with Hereditary Bleeding Disorders

PURPOSE OF REVIEW

Hereditary bleeding disorders may have a wide variety of clinical presentations ranging from mild mucosal and joint bleeding to severe central nervous system (CNS) bleeding, of which intracranial hemorrhage (ICH) is the most dreaded complication. In this review, we will discuss the pathophysiology of specific hereditary bleeding disorders, namely, hemophilia A, hemophilia B, and von Willebrand disease (vWD); their clinical manifestations with a particular emphasis on neurological complications; a brief overview of management strategies pertaining to neurological complications; and a review of literature guiding treatment strategies.

RECENT FINDINGS

ICH is the most significant cause of morbidity and mortality in patients with hemophilia. Adequate control of bleeding with the administration of specific factors or blood products, identification of risk factors for bleeding, and maintaining optimal coagulant activity are essential for appropriately managing CNS bleeding complications in these patients. The administration of specific recombinant factors is tailored to a patient's pharmacokinetics and steady-state levels. During acute bleeding episodes, initial factor activity should be maintained between 80 and 100%. Availability of monoclonal antibody Emicizumab has revolutionized prophylactic therapies in patients with hemophilia. Management of ICH in patients with vWD involves using plasma-derived factor concentrates, recombinant von Willebrand factor, and supportive antifibrinolytic agents individualized to the type and severity of vWD. Hemophilia and vWD are the most common hereditary bleeding disorders that can predispose patients to life-threatening CNS complications-intracranial bleeds, intraspinal bleeding, and peripheral nerve syndromes. Early care coordination with a hematologist can help develop an effective prophylactic regimen to avoid life-threatening bleeding complications in these patients. Further research is needed to evaluate using emicizumab as an on-demand treatment option for acute bleeding episodes in patients with hemophilia.

Effect of Neurodynamics Nerve Flossing on Femoral Neuropathy in Haemophilic Patients: A randomized controlled study

OBJECTIVE

Heamophilia is considered a disorder in both children and adolescents which may affect their quality of life seriously than their normal peers; this study investigated the impact of the Neurodynamics Nerve Flossing Technique (NFT) on femoral neuropathy in patients with haemophilia.

METHOD

Thirty haemophilic children with Femoral Neuropathy were randomly allocated into two equivalent groups; the study group which received Neurodynamics NFT of the femoral nerve and conventional therapy program, and the control group which received only the conventional therapy program, three sessions/week for 12 weeks. Femoral nerve motor conduction velocity (MCV) and level of pain sensation according to the Visual Analogue Scale (VAS), were assessed pre and post interventions.

RESULTS

post-treatment comparison between both groups revealed that there was a significant increase in femoral nerve MCV and reduction of pain sensation of the study group compared to the control group (p<0.05).

CONCLUSION

Neurodynamics Nerve flossing had a clear effect in the treatment of femoral neuropathy in children with haemophilia.
