ABSTRACT

Multiple sclerosis (MS) prevalence is higher in Caucasian (CA) populations, narrowing the analysis of the impact of Afro-descendant (AD) populations in disease outcomes. Even so, recent studies observed that AD patients have a more severe course. The main objective of this study is to confirm and discuss, through a systematic review, that being AD is a risk factor for disability accumulation and/or severe progression in patients with MS. A systematic review of published data in the last eleven years was performed, which evaluated clinical aspects and long term disability in patients with MS. Fourteen studies were included. Of these fourteen articles, thirteen observed a relationship between ancestry and poorer outcome of MS. African ancestry is a condition inherent in the patient and should be considered as an initial clinical characteristic affecting prognosis, and influencing which therapeutic decision to make in initial phases.

RESUMO

A prevalência da esclerose múltipla (EM) é maior em populações caucasianas (CA), o que limita a análise do impacto da Afrodescendencia (AD) nos desfechos da doença. Apesar disto, estudos recentes observaram que a AD determina um curso clínico mais severo. O principal objetivo deste estudo é confirmar e discutir, por meio de uma revisão sistemática, que a afrodescendência é um fator de risco para acúmulo de incapacidade e/ou progressão mais severa em pacientes com EM. Foi realizada uma revisão sistemática de trabalhos publicados nos últimos onze anos que avaliaram aspectos clínicos e incapacidade a longo prazo em pacientes com EM. Quatorze artigos foram incluídos. Entre eles, treze observaram uma relação entre AD e pior prognóstico da EM. AD é uma condição inerente ao paciente e deveria ser considerada, assim como as características clínicas relacionadas ao prognóstico, influenciando a decisão terapêutica a ser tomada nas fases iniciais da doença.
