MS in South America

 Cristiano E, Rojas J, Romano M, Frider N, Machnicki G, Giunta D, Calegaro D, Corona T, Flores J, Gracia F, Macias-Islas M, Correale J.  The epidemiology of multiple sclerosis in Latin America and the Caribbean: a systematic review. Mult Scler. 2012 Oct 8. [Epub ahead of print]

The incidence and prevalence of multiple sclerosis (MS) varies geographically as shown through extensive epidemiological studies performed mainly in developed countries. Nonetheless, scant data is available in Latin America and the Caribbean (LAC). The objective of this review is to assess epidemiological data of MS in LAC. We conducted a systematic review of published articles and gray literature from January 1995 to May 2011. Twenty-two studies met the inclusion criteria after full-text review. Incidence data were found in only three studies and ranged from 0.3 to 1.9 annual cases per 100,000 person-years. Prevalence was reported in 10 studies and ranged from 0.83 to 21.5 cases per 100,000 inhabitants. The most prevalent sub type of MS was the relapsing-remitting form (48% to 91% of the series). No data about mortality were found. This study showed low frequency for MS in LAC compared with North American and European countries. The role of environmental and genetic factors should be well studied, providing new insights about its aetiology.
You can read the information, do we need yet more genetic studies?

  1. Has there ever been a study done on first-generation Americans or Europeans with LAC origins? I'm a first-generation American and so far as my Peruvian relatives know, the only one in the family who's been diagnosed with MS. So I remain the only one, I've told my younger sibling to get his vitamin D levels tested and start taking D3 daily.

  2. The article is so helpful, since there are lots of information on diagnosis & multiple sclerosis treatment which I have been looking for the past few weeks for my father. Hope he will get well soon after the treatment.
