RESUMO

PURPOSE: To validate and culturally adapt the Sexual Health Inventory for Men (IIEF-5) and the Premature Ejaculation Diagnostic Tool (PEDT), to compare the frequency and severity of erectile dysfunction (ED) and premature ejaculation (PE) in male individuals with MS (mwMS) in comparison with healthy controls (HC) and to investigate predictors of the severity of ED and PE in mwMS. METHODS: 216 consecutive mwMS and 37 HC completed IIEF-5 and PEDT. Additionally, 114 mwMS completed the Modified Fatigue Impact Scale (MFIS), Beck Depression Inventory (BDI-2), Composite Autonomic System Score-31 (COMPASS-31), and the 5-level EQ-5D questionnaire. RESULTS: The test-retest reliability was satisfactory for both questionnaires, with acceptable reliability for both questionnaires. mwMS scored less on IIEF-5 compared to HC (23, IQR 18.25-25 vs 24, IQR 20.25-25, p = 0.028). ED was present in 39.4 % of mwMS and 27.8 % of HC (p = 0.198). Definite PE was present in 12.1 %, and possible PE in 7.8 % of mwMS; and 5.6 % and 11.1 % of HC respectively (p = 0.496). An increase in EDSS was a positive predictor (Exp(B) 1.455, 95 %CI 1.135-1.886, p = 0.003) and the presence of cremasteric reflex was a negative predictor (Exp(B) 0.381, 95 %CI 0.183-0.790, p = 0.010) for the presence of ED. For the PE, disease duration was the only positive predictor in a univariable logistic regression (Exp(B) 1.084, 95 %CI 1.019-1.153, p = 0.070). CONCLUSION: SD is frequent in mwMS with EDSS being a positive and the presence of cremasteric reflex a negative predictor of ED and disease duration a positive predictor of PE symptoms.

RESUMO

OBJECTIVES: To investigate differences in beat-to-beat systolic blood pressure variability (SBPV) in people with secondary progressive MS (pwSPMS), clinically isolated syndrome (pwCIS) and healthy controls (HC). METHODS: This retrospective case-control study included 46 pwSPMS, 46 pwCIS and 44 HC. A semi-automated software made with MATLAB R2019b (The MathWorks, Inc.) was used for the evaluation of SBPV. The frequency domain characteristics observed were the power spectrum in the LF and HF bands and the LF/HF ratio. Data is expressed in absolute power (mmHg2) of LF and HF and ratio (LF/HF) during both supine and tilt-up phases of testing. RESULTS: There were no significant differences in mean systolic (sBP) or diastolic blood pressure (dBP) values during supine and tilt-up phases of testing between groups. During the supine phase of testing LF and LF/HF were significantly lower in the SPMS group (4.17±5.38 and 3.52±2.34, respectively) compared to the CIS (5.42±3.59, p = 0.015 and 5.92±4.63, p = 0.029, respectively) and HC group (6.03±4.55, p = 0.011 and 6.52 ±â€¯5.09, p = 0.010, respectively), while during the tilt-up phase, LF was significantly lower compared to both the CIS and HC group, and HF was significantly lower only compared to the CIS group. CONCLUSION: SBPV is altered in pwSPMS compared to pwCIS and normal controls. Further research in the field of MS related dysautonomia is warranted not only because of its relevance to comorbidities and MS symptoms, but also because of its likely involvement in the pathophysiology of MS.

RESUMO

OBJECTIVES: The aim of this study was to investigate the short- and long-term effects of siponimod on autonomic nervous system (ANS) function, in people with secondary progressive multiple sclerosis (pwSPMS) METHODS: The following ANS tests were performed in 26 pwSPMS: a 10 min supine resting position, Valsalva maneuver, deep breathing test and a 10 min tilt-up table test. Heart rate variability (HRV) was performed for the 10 min in supine resting position (M0) and for a 3 h period after siponimod treatment initiation (M0s1-6). All ANS tests were repeated after at least 6 months of treatment with siponimod (M6). RESULTS: In all 6 intervals after siponimod ingestion (M0s1-6), standard deviation of NN intervals (SDNN) was higher compared to M0. After 6 months of continuous treatment with siponimod, SDNN was significantly lower compared to M0. At M6, Valsalva ratio and respiratory sinus arrhythmia were lower compared to M0 values (1.510±0.338 vs 1.864±0.456, p=0.003 and 7.969±2.865 vs 13.091±4.687, p<0.001, respectively). Cardiovagal index was significantly higher at M6 compared to M0 (1 (range 0-2) vs 0 (range 0-1), p=0.008, respectively). Active Magnetic Resonance Imaging (MRI) one year prior to starting siponimod was a positive predictor of M6 SDNN and Adrenergic Index (AI) at M0 was a negative predictor of M6 SDNN. CONCLUSION: This study has shown an inverse relationship in short- versus long-term effects of siponimod on ANS function. A shift towards parasympathetic predominance was observed during the first three hours after ingestion, while after 6 or more months of continuous treatment with siponimod, a shift towards sympathetic predominance was observed.
