CDC HAN404: Patients Receiving Eculizumab at High Risk for Meningococcal Disease Despite Vaccination7/10/2017
Message Details Date Sent: 07/07/2017 12:26 PM EDT Sender: Michigan Health Alert Network Subject: CDC HAN404: Patients Receiving Eculizumab at High Risk for Meningococcal Disease Despite Vaccination Message:
Summary Eculizumab (Soliris®) recipients have a 1,000 to 2,000-fold greater risk of invasive meningococcal disease compared to the general U.S. population. The Food and Drug Administration (FDA)-approved prescribing information for eculizumab includes a black box warning for increased risk of meningococcal disease, and the Advisory Committee on Immunization Practices (ACIP) recommends meningococcal vaccination for all patients receiving eculizumab. Recent data show that some patients receiving eculizumab who were vaccinated with the recommended meningococcal vaccines still developed meningococcal disease, most often from nongroupable Neisseria meningitidis, which rarely causes invasive disease in healthy individuals. Recommendations for Healthcare Providers Healthcare Providers:
Eculizumab is most commonly prescribed for treatment of 2 rare blood disorders: atypical hemolytic uremic syndrome (aHUS) and paroxysmal nocturnal hemoglobinuria (PNH). Through a request for data on meningococcal disease cases reported to state health departments, the U.S. Centers for Disease Control and Prevention (CDC) identified 16 cases of meningococcal disease in eculizumab recipients in the United States from 2008 through 2016; 11 (69%) of these were caused by nongroupable N. meningitidis. Meningococcal conjugate (MenACWY) vaccine targets serogroups A, C, W, and Y, and provides no protection against nongroupable N. meningitidis. Serogroup B meningococcal (MenB) vaccines are licensed specifically for protection against serogroup B meningococcal disease. Researchers have not assessed the extent of any potential cross protection for nongroupable N. meningitidis strains. For More Information
