Lower urinary tract symptoms and perineal function in women with and without fibromyalgia: a cross-sectional study

Pelvic floor dysfunctions in women with fibromyalgia: A cross-sectional study

BACKGROUND

Fibromyalgia (FM) is a rheumatic syndrome that causes musculoskeletal disorders and is associated with several problems that affect quality of life. As the musculoskeletal system is affected, it can have an impact on the pelvic floor muscles, leading to pelvic floor dysfunction (PFD).

OBJECTIVE

Investigate the occurrence of PFD, such as urinary incontinence (UI) and anal incontinence (AI), sexual problems, and pelvic organ prolapse (POP), in women with FM compared to a control group composed of women without FM; and investigate the association between FM and PFD.

STUDY DESIGN

This was an online cross-sectional survey. Demographic and anthropometric data, the description of PFD (UI, nocturia, AI, genital-pelvic pain/penetration disorder, and POP), and previous obstetric history were collected through a web-based questionnaire. The groups were compared using the independent t-test for quantitative variables and the chi-square test for categorical variables. The association between FM and PFD was tested using logistic regression analysis.

RESULTS

A total of 175 women answered the questionnaire (97 with FM and 78 healthy controls). The women with FM reported significantly more UI, mixed urinary incontinence, AI, POP, and vaginismus than the healthy controls (p ≤ 0.05). FM was associated with mixed urinary incontinence (OR: 2.6; 95 % CI: 1.1-6.4; p = 0.04), anal incontinence (OR: 2.9; 95 % CI: 1.3-6.1; p = 0.01), and flatus incontinence (OR: 2.6; 95 % CI: 1.2-5.4; p = 0.01).

CONCLUSION

The prevalence of PFD was significantly higher in women with FM compared to healthy women. Indeed, the women with FM were 2.6-fold to 2.9-fold more likely to report mixed urinary incontinence, anal and flatus incontinence than those in the control group. The present findings show possible impairment of the pelvic floor musculature in women with FM.

The association between overactive bladder and fibromyalgia: A systematic review and meta-analysis

BACKGROUND

Overactive bladder is a common syndrome that significantly affects the quality of life. Fibromyalgia is characterized by widespread pain, impacting patients' lives. The exact mechanisms of the two syndromes remain unknown, but there is an overlap between the suspected pathophysiologies.

OBJECTIVE

To present an overview of the current research on the association between overactive bladder (OAB) and fibromyalgia.

SEARCH STRATEGY

A systematic search of four electronic databases was conducted.

SEARCH STRATEGY

Studies examining the correlation between OAB and fibromyalgia with female patients aged over 18 years were included.

DATA COLLECTION AND ANALYSIS

Two reviewers screened the studies for eligibility. Eligible studies were screened for quality. A meta-analysis was performed for eligible studies.

MAIN RESULTS

Seven studies were included in the final review, of which six presented a positive association between the syndromes. The studies demonstrated a positive association between fibromyalgia and the severity of OAB and an adverse effect on the quality of life related to OAB. A mean effect size of 1.96 (95% confidence interval 0.85-3.06) was calculated.

CONCLUSION

OAB and fibromyalgia are both complex and multifactorial syndromes. The study presents an association between them, but additional studies on the topic should be conducted for a more precise conclusion.

Lower urinary tract symptoms in rheumatoid arthritis and spondyloarthritis male patients versus controls

Background. We aimed to evaluate the severity of lower urinary tract symptoms (LUTS) in rheumatoid arthritis (RA) and spondyloarthritis (SpA) male patient versus control, then to determine the relation of LUTS with rheumatic diseases (RD) characteristics and with erectile dysfunction (ED).

Methods. We conducted a cross-sectional case control study including 50 men with RA or SpA and 50 healthy controls. LUTS were evaluated by the International Prostate Symptom Score (IPSS). LUTS bother was evaluated by the Quality of life (QoL) score, which ranges from 0 to 6. LUTS bother was considered if QoL score exceeded 2. Moreover, erectile function was assessed by the International Index of Erectile Function-5 (IIEF5) (ED if score < 21).

Results. LUTS were significantly more severe in RD patients than controls (p = 0.03). However, there was no difference between the two groups in LUTS bother (QoL) (p = 0.2). Comparing RA and SpA showed no difference as to the severity of LUTS or effect of bother on QoL (p = 0.13, p = 0.5). The prevalence of ED in RD patients was not significantly higher than controls (80% versus 70%; p = 0.2).There were also no differences either between RA and SpA groups (p = 0.74).

The severity of LUTS for patients with RD (RA and SpA) was significantly associated with age (p = 0.001), age at disease onset (p = 0.002) and ED (p = 0.008).

Conclusion. According to our study, men with RD seem to be exposed to more severe LUTS than controls. Also, the severity of LUTS was associated with ED, age of patients and the age of disease onset.

Sexual performance and pelvic floor muscle strength in patients with fibromyalgia: a controlled cross-sectional study

BACKGROUND

Fibromyalgia (FM) is characterized by chronic and widespread pain, sleep disturbances, fatigue, psychological distress and morning stiffness. These patients also present symptoms such as depression, sexual dysfunctions and reproductive problems. Sexuality involves several aspects, including pelvic floor functionality, and one question is whether the sexual performance of women with fibromyalgia is associated with pelvic floor function or other characteristics of the disease.

OBJECTIVE

The aim of this study was to gauge the association between perineal function and sexual performance in women with and without fibromyalgia.

METHODS

We performed a cross-sectional study with 109 sexually active women from 19 to 65 years of age, either suffering from fibromyalgia (FM group, n = 51) or free from fibromyalgia (non-FM group, n = 58). Perineal function was measured with the use of perineometry and digital vaginal palpation (PERFECT Scheme), while sexual performance was assessed by the Sexual Quotient Female questionnaire (QS-F).

RESULTS

Patients with fibromyalgia presented poor sexual performance compared to those without fibromyalgia (QS-F score 58 (32-66) vs. 66 (56-70); p = 0.002) as well as lower pelvic floor muscle strength measured by perineometry (32.5 (18.2-40.5) vs. 37.9 (23.4- 57.3); p = 0.03). Patients without fibromyalgia presented a positive correlation between perineometry and QS-F (r = 0.22; p = 0.038), while those with fibromyalgia presented no correlation between those two variables (r = 0.22; p = 0.12). The regression model showed an association between sexual performance and the presence of fibromyalgia, pelvic floor muscle strength (perineometry) and age, according to the following equation: sexual performance = 48.52 + (9.5 * non-FM group) + (0.23 * perineometry)-(0.4 * age), with adjusted R² = 0.19.

CONCLUSION

Women with FM present poor sexual performance and lower pelvic floor muscle strength compared to those without FM. However, the correlation between these variables among women without FM was not observed in women with FM. Sexual performance showed a positive association with absence of fibromyalgia and higher pelvic floor muscle strength, and a negative association with age.

Electrodiagnostic Abnormalities Associated with Fibromyalgia

PURPOSE

Increasing evidence suggests that fibromyalgia most likely represents a neurological dysfunction. We previously hypothesized that at least some fibromyalgia cases may be caused by irritation of nerve root fibers and sensory neurons due to moderately increased cerebrospinal pressure. Because of the rostro-caudal hydrostatic pressure gradient, neurogenic abnormalities are expected to be most pronounced in sacral nerve roots. The purpose was to review electrodiagnostic tests of patients with fibromyalgia.

METHODS

A retrospective review of electrodiagnostic test results, including the lumbar and sacral nerve root myotomes of patients diagnosed with fibromyalgia according to the 1990 criteria of the American College of Rheumatology was done.

RESULTS

All 17 patients were female. Sural nerve responses could not be elicited in 12% and S1-Hoffmann reflex latencies were increased in 41%. In 12% of the patients, fibular motor nerve distal latency and conduction velocity were outside normal limits. Needle-EMG revealed neurogenic motor unit potentials in 0% of L2, 6% of L3, 29% of L4, 71% of L5, 47% of S1, 94% of S2, and 76% of S3-S4 myotomes. S3-S4 nerve-supplied anal reflexes were delayed in 94%.

CONCLUSION

This is the first time that electrodiagnostic data of both lumbar and sacral nerve root myotomes in fibromyalgia patients are presented. All patients showed neurogenic abnormalities that were more pronounced in the sacral than in the lumbar myotomes with a rather patchy distribution pattern. We propose that, in addition to skin punch biopsies to assess small fiber neuropathy, assessment of the anal reflex may be a useful part of the diagnostic pathway in patients with fibromyalgia.

The Fibromyalgia Bladder Index in 100 consecutive women with fibromyalgia

INTRODUCTION AND HYPOTHESIS

The Fibromyalgia Bladder Index (FBI) is a validated instrument to quantify bothersome bladder symptoms specifically in women with fibromyalgia syndrome (FMS). The FBI includes two sub-scales: one addressing urinary urgency and bladder pain (UP), the other addressing urinary frequency and nocturia (FN). The objectives of this study are to evaluate the FBI in a cohort of patients with FMS, to correlate it with certain characteristics in this cohort, and to compare it with controls.

METHODS

We performed a case-control study of 100 women with FMS and 155 controls. Demographic data, comorbidities, and other characteristics were registered. Comparison between FBI scores of participants with and without FMS, as well as correlation of FBI scores with the characteristics of FMS patients, were undertaken using independent two-sample t test for continuous outcomes and Pearson's Chi-squared test for categorical outcomes.

RESULTS

The mean UP subscale score of the FBI was significantly higher in the FMS group (10.29 ± 5.61) compared with the controls (1.65 ± 2.65; (p = 0.001). The mean FN subscale score was significantly higher in the FMS group (9.93 ± 5.37) compared with the controls (2.95 ± 3.27; p = 0.001). FMS patients diagnosed >3 years ago had a higher UP subscale score and a higher FN subscale score compared with FMS patients diagnosed <3 years ago (p = 0.020 and p = 0.024 respectively). Menopause and parity significantly increased the FBI scores. Smoking and a history of depression did not significantly affect any of the FBI subscale scores in the FMS group.

CONCLUSION

Women with FMS suffer from bothersome bladder symptoms that can be readily identified and quantified.
