Abstract

Abstract : Background: Rheumatoid arthritis (RA) is an inflammatory and disabling disease whose expression and clinical course is influenced by gender. In developed countries the prevalence of RA is 0.5–1%, with a ratio 3:1 female:male. Comparative gender studies have shown that women have greater functional disability, disease activity and pain than men1. Objectives: The purpose of this study is to describe and compare the clinical and serological characteristics of a cohort of men with RA. Methods: A cross-sectional study was conducted in patients with established diagnosis of RA (American College of Rheumatology criteria 1988) from the Luis Vernaza Hospital and a private rheumatology center (CERER). The data included clinical manifestations, demographic data, comorbidities, habits, treatment, activity index DAS28-CRP, HAQ-DI disability index and the PHQ-9 questionnaire. The statistical program SPSS V. 22 was used to analyze the data and calculate frequencies, percentages, means, ranges, Spearman correlation and ANOVA coefficient. Statistical significance used was 0.05, with a 95% reliability. Results: A cohort of 50 men was compared with a control group of 50 women. Most men worked while women stayed at home (72% and 66%, respectively, p=0.000). Tobacco and alcohol were more common in men (34% vs 8% p=0.001 and 38% vs. 0% p=0.000 respectively). The delay in the first visit to the specialist was shorter in men than in women (24 vs 32 months) and they had a longer follow-up (55 vs 41 months). In clinical manifestations, women had greater fatigue (60% vs 30% p=0.003), weight loss (44% vs 20% p=0.010), loss of appetite (54% vs 12% p=0.000) and depression (60% vs 22% p=0.000). There was no significant difference in comorbidities and treatment between the groups. Men had lower disease activity: VSG (23 vs 47 p=0.046), DAS 28 (2.5 vs 3.4 p=0.011), HAQ DI (0.37 vs 1.12 p=0.000), functional disability (12% vs 36% p=0.005), severe disability (2% vs 22% p=0.002), painful joints (2 vs 8 p=0.000), swollen joints (2 vs 6 p=0.000) and VAS of doctor (2 vs 3 p=0.047). Conclusions: This is the first cohort study of men with RA in Ecuador. As shown in other international studies2–3, our results confirm that men have a less aggressive disease.
