Efficacy of Anakinra Treatment in two Moroccan Patients With Mevalonate Kinase Deficiency

Mevalonate kinase deficiency (MKD) is a rare hereditary autoinflammatory disease, with a widely variable clinical spectrum. It is characterized by febrile recurrent episodes and systemic inflammation. Data on therapeutic options for MKD are still limited and remain unknown in our country. We report Moroccan cases with MKD referred in our unit and treated with Anakinra, an interleukin-1 receptor antagonist. Through this study, we evaluate the efficacy of this bioagent, in our 2 MKD patients, in whom Anakinra has shown a complete clinical remission, with a remaining mild inflammation for one case, and normalization of growth with rare episodes of cervical adenopathies for the second case. Our experience provides an additional argument supporting the efficacy of Anakinra treatment, demonstrated previously but still lacks of objective data.
