Successful Rapid Drug Desensitization with A Modified Protocol To Alemtuzumab in A Multiple Sclerosis Patient with Severe Immediate-Type Hypersensitivity Reaction

Alemtuzumab is a humanized monoclonal antibody targeting the CD52 antigen on lymphocyte surfaces. The intravenous administration of alemtuzumab provokes the depletion of lymphocytes by antibody-dependent and complement-mediated cellular cytotoxicity. Resulting cytotoxicity leads to 'first-dose infusion-related reactions in more than 90% of the patients, fewer than 3% being severe cases. We present the first successful modified rapid drug desensitization (RDD) protocol to alemtuzumab in an active relapsing-remitting multiple sclerosis (RRMS) patient. The forty-year-old female patient had an immunologically-mediated mixed-type (co-occurring IgE-mediated and cytokine release syndromes) hypersensitivity reaction (HSR) verified with a drug skin test. As the patient had severe HSR and there was no other option to treat RRMS at that time; two courses of 12 mg alemtuzumab with one-year intervals were administrated successfully using the modified 12-step intravenous RDD protocol. By experience, RDD is known as a safe and effective therapy option allowing alemtuzumab treatment targeted for the aforementioned type of MS

Coexistence of restless legs syndrome and multiple sclerosis aggravates anxiety and depression

Background: Among the comorbidities that accompany multiple sclerosis (MS), restless legs syndrome (RLS) is one of the most common. Anxiety and depression are common psychological comorbidities that impact the quality of life of patients with MS (PwMS), as well as patients with RLS. Objective: To investigate the psychiatric burden of MS and RLS coexistence, we conducted a nationwide, multicenter and cross-sectional survey. Methods: Participants were assessed by using demographic and clinical parameters along with the Hamilton Anxiety and Hamilton Depression Scales (HAM-A and HAM-D). Results: Out of the 1,068 participants, 173 (16.2%) were found to have RLS [RLS(+)] and 895 (83.8%) did not [RLS(-)]. The mean scores for HAM-A and HAM-D were significantly higher among RLS(+) subjects than among RLS(-) subjects (p<0.001 for all variables). Conclusions: According to our data, the presence of RLS in PwMS may increase the occurrence of both anxiety and depression symptoms. Awareness and treatment of RLS in PwMS could possibly reduce the symptoms of psychiatric comorbidities originating from RLS
