SAT0627-HPR SEXUAL QUALITY OF LIFE IN 39 FEMALE PATIENTS WITH IDIOPATHIC INFLAMMATORY MYOPATHIES

Background: Symptoms related to idiopathic inflammatory myopathies (IIM) such as weakness of skeletal muscles, pulmonary and articular involvement may have a negative impact on all aspects of life including sexual life. Objectives: To assess sexual functioning in female IIM patients compared to age-/sex-matched healthy controls (HC) and to analyze the potential impact of clinical features on sexual health. Methods: In total, 39 women (29 currently have a partner) with IIM [mean age: 54.7, disease duration: 11.8 years, dermatomyositis (DM, 19)/ polymyositis (PM, 16)/ necrotizing myopathy (IMNM, 3)/ inclusion body myositis (IBM, 1)] and 39 healthy controls (30 currently have a partner, mean age: 54.7 years) without rheumatic diseases filled in 11 well-established and validated questionnaires assessing sexual function (FSFI, SFQ28, BISFW), quality of sexual life (SQoL-F), pelvic floor function (PISQ-12, PFIQ-7), fatigue (FIS, MAF), physical activity (HAP), and depression (BDI-II). A standard laboratory testing was performed. Data are presented as mean ± SEM. Results: Patients with IIM reported significantly higher prevalence and greater severity of sexual dysfunction (FSFI, BISF-W, SFQ28) and worse sexual quality of life (SQoL-F) compared to HC (table 1). Worse scores in IIM patients were associated with increased inflammation [CRP: FSFI (r=-0.378, p=0.0190), SFQ-28 Satisfaction domain (r=-0.346, p=0.0356), SQoL-F (r=-0.331, p=0,0479], greater muscle weakness of m. gluteus maximus/ m. gluteus medius/ m. iliopsoas [FSFI: (r=0.426, p=0.0368), (r=0.370, p=0.0368), (r=0.394, p=0.0252), SQoL-F (r=0.504, p=0.0044), (r=0.421, p=0.0204), (r=0.462, p=0.0100)], greater fatigue [FIS: FSFI (r=-0.358, p=0.0154), BISF-W (r=-0.415, p=0.0084), SQoL-F (r=-0.327, p=0.0481)], more severe depression [BDI-II: FSFI Arousal domain (r=-0.357, p=0.0299)], deteriorated quality of life [HAQ: BISF-W (r=-0.464, p=0.0033)], and worse ability to perform physical activities [HAP: FSFI (r=0.405, p=0.0105), BISF-W (r=0.480, p=0.0019)]. No associations were found with disease duration, prednisone dose or serum levels of muscle enzymes. Conclusion: Women with IIM reported significantly impaired sexual function and sexual quality of life compared to age-matched healthy controls. Worse scores in IIM were associated with disease activity, physical activity, fatigue, depression and quality of life. Acknowledgments: Supported by MHCR 023728, SVV 260373 and GAUK 1578119.
