Abstract
ABSTRACT Background The objective of our study was to describe the availability of diagnostic tests and treatment for MS and NMOSD in Latin America (LATAM). Methods A survey instrument was used in a sample of physicians from LATAM countries. The goal of the survey was to understand availability of: 1) imaging tests for diagnosing MS and NMOSD and its barriers; 2) diagnostic laboratory tests for diagnosing MS and NMOSD and its barriers; and 3) treatments for MS and NMOSD in the acute and chronic phases of the disease. Results Responses were received from 80 physicians. AQP4-ab test was available in 54% of the countries and MOG-ab test in 42%. All of countries had available use of high doses of intravenous methylprednisolone, oral steroids, plasmapheresis, and intravenous immunoglobulins for relapses. For NMOSD, 93% of the countries were able to use azathioprine and mycophenolate mofetil, and 87% rituximab. In MS, 93% of countries had available to them IFN beta, 69% glatiramer acetate, 75% teriflunomide, 93% fingolimod, 69% dimethyl-fumarate, 75% cladribine, 69% natalizumab, 93% ocrelizumab and 81% alemtuzumab. The most common challenge and barrier identified was the cost of medications. Conclusion The present study allows an understanding of the delivery of care for MS and NMOSD in the region.
