Sexual dysfunction and self-perceived sexual health in patients with rheumatoid arthritis and systemic lupus erythematosus: results from a cross-sectional survey.

Sexual dysfunction (SD) has been associated with worse quality of life and higher disease activity in patients with rheumatic diseases, yet it is still not regularly addressed during routine rheumatologic evaluations. This study aimed to determine the prevalence of sexual dysfunction in patients with rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE) and evaluate their perception of their sexual health. We performed a retrospective study in an outpatient rheumatology clinic to evaluate patients over 18 years old with a diagnosis of RA or SLE through the Spanish version of the Arizona Sexual Experiences Scale (ASEX) and the Sexual Health Perception Survey (SHEPS), a questionnaire of 6 items designed in our clinic. Additionally, we applied the Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F version 4) and the Hospital Anxiety and Depression Scale (HADS). A total of 567 patients were evaluated with SHEPS, most of whom were women with a median age of 50 years (IQR: 34) and a median disease duration of 5 years (IQR: 9). Through the ASEX, we found that 67% of the patients with RA and 60% of the patients with SLE experienced SD. Patients reported the level of sex drive, arousal, and the ability to achieve orgasms as the areas with the most difficulties. Most patients did not know their disease could affect their sexuality and had never addressed these issues with their rheumatologists, but almost all of them were willing to. Our findings highlight the importance of addressing sexual health issues regularly during rheumatologic evaluations.

Rheumatoid arthritis-associated antibodies in healthy first-degree relatives of RA patients.

Rheumatoid arthritis (RA) affects approximately 1.5% of the population worldwide and 0.5-3.3% of the Mexican population. The presence of rheumatoid factor (RF), anti-citrullinated protein antibodies (ACPA) and anti-carbamylated protein (anti-CarP) antibodies has been described in populations at risk of RA development, such as first-degree relatives (FDR). Anti-CarP antibodies are present in RA patients (44%), FDR of RA patients (18%) and healthy controls (4.7%). Anti-CarP antibodies have not been described in FDR of the Mexican population. The objective of this study was to determine the prevalence of Rheumatoid Factors (RF) isotypes, ACPA and anti-CarP antibodies isotypes in FDR of RA patients. An observational, cross-sectional study, in an FDR of RA cohort, was performed. We measured IgA, IgG and IgM isotypes of RF, ACPA and anti-CarP antibodies. A total of 144 FDRs from 99 RA patients were enrolled. The prevalence of anti-CarP antibodies was 2.8% for IgA, 4.2% for IgG, whereas IgM was not detected. The serologic association was for RF/ACPA 4.48%, RF/anti-CarP 2.7%, FR 64.5%, ACPA 1.3%, ACPA/anti-CarP 0.69%, anti-CarP 3.4%, and no RF/ACPA/anti-CarP was observed. We found a low prevalence of anti-CarP antibodies in our cohort of FDR of RA patients, but the prevalence of ACPA and RF were higher than other cohorts previously reported.
