ABSTRACT

Objective The study aims to investigate the presence of pain amongst multiple sclerosis (MS) patients. Method One hundred MS patients responded to questionnaires evaluating neuropathic and nociceptive pain, depression and anxiety. Statistical analysis was performed using the Mann–Whitney U, Chi-Square and two-tailed Fisher’s exact tests and multivariate logistic regression. Results Women had a statistically higher prevalence of pain (p = 0.037), and chances of having pain after the age of 50 reduced. Women with pain had a statistically significant lower number of relapses (p = 0.003), restricting analysis to those patients with more than one relapse. After the second relapse, each relapse reduced the chance of having pain by 46%. Presence of pain was independent of Expanded Disability Status Scale (EDSS) anxiety, and depression. Conclusion Our findings suggest a strong inverse association between relapses and pain indicating a possible protective role of focal inflammation in the control of pain. .


Objetivo O estudo tem como objetivo investigar a presença de dor entre pacientes com esclerose múltipla (EM). Método Cem pacientes com EM responderam a questionários avaliando dor neuropática e nociceptiva, depressão e ansiedade. A análise estatística foi realizada através dos testes de Mann-Whitney U, Qui-Quadrado, two tailed Fisher exact test e regressão logística multivariada. Resultados As mulheres apresentaram estatisticamente uma maior prevalência de dor (p = 0,037), e as chances de ter dor após a idade de 50 reduziram. As mulheres com dor tinham um número com significância estatística reduzido de surtos (p = 0,003), restringindo a análise aos pacientes com mais de um surto. Após o segundo surto, cada surto reduziu a chance de ter dor em 46%. A presença de dor foi independente da Expanded Disability Status Scale (EDSS) ansiedade e depressão. Conclusão Nossos resultados sugerem uma forte associação inversa entre o surto e a dor, indicando um possível papel protetor da inflamação focal no controle da dor. .
