Pain Symptoms in Fibromyalgia Patients with and without Provoked Vulvodynia

Role of sexuality in women with chronic pain: Results from an Italian cross-sectional study on chronic headache, fibromyalgia, and vulvodynia

Background/objectives

To compare sexual functioning, genital pain, and satisfaction among women diagnosed with various Chronic pain (CP) conditions. Additionally, it seeks to explore the role of sexual factors in predicting levels of central sensitization (indicative of CP-related mental and physical distress), physical, and mental quality of life (QoL) for each condition individually.

Methods

From April 2023 to January 2024, 1006 women categorized into five groups (Chronic Headache - CH; Fibromyalgia - FM, Vulvodynia - VU, Comorbidity group - CO, and Healthy Controls - HC) completed an online protocol.

Results

All groups reported sexual impairment: VU group exhibited the highest genital pain prevalence (97.93 %), followed by CO (74.29 %) and FM (55.91 %). ANCOVAs indicated lower sexual functioning scores for FM, VU, and CO compared to HC and CH. VU and CO reported lower satisfaction scores than other groups. Genital pain emerged as the primary predictor of central sensitization across all groups except controls. Regarding mental QoL, sexual satisfaction was significant for CH and CO, while genital pain and sexual satisfaction were significant for VU.

Conclusion

This study emphasizes the importance of integrating genito-pelvic pain assessment and addressing related sexual difficulties in CP diagnostics and care to enhance overall well-being and QoL.

Distinct neural signaling characteristics between fibromyalgia and provoked vestibulodynia revealed by means of functional magnetic resonance imaging in the brainstem and spinal cord

Introduction

Fibromyalgia and provoked vestibulodynia are two chronic pain conditions that disproportionately affect women. The mechanisms underlying the pain in these conditions are still poorly understood, but there is speculation that both may be linked to altered central sensitization and autonomic regulation. Neuroimaging studies of these conditions focusing on the brainstem and spinal cord to explore changes in pain regulation and autonomic regulation are emerging, but none to date have directly compared pain and autonomic regulation in these conditions. This study compares groups of women with fibromyalgia and provoked vestibulodynia to healthy controls using a threat/safety paradigm with a predictable noxious heat stimulus.

Methods

Functional magnetic resonance imaging data were acquired at 3 tesla in the cervical spinal cord and brainstem with previously established methods. Imaging data were analyzed with structural equation modeling and ANCOVA methods during: a period of noxious stimulation, and a period before the stimulation when participants were expecting the upcoming pain.

Results

The results demonstrate several similarities and differences between brainstem/spinal cord connectivity related to autonomic and pain regulatory networks across the three groups in both time periods.

Discussion

Based on the regions and connections involved in the differences, the altered pain processing in fibromyalgia appears to be related to changes in how autonomic and pain regulation networks are integrated, whereas altered pain processing in provoked vestibulodynia is linked in part to changes in arousal or salience networks as well as changes in affective components of pain regulation.

New Insights about Chronic Pelvic Pain Syndrome (CPPS)

BACKGROUND

Chronic pelvic pain syndrome (CPPS) is one of the common diseases in urology and gynecology. CPPS is a multifactorial disorder where pain may originate in any of the urogynecological, gastrointestinal, pelvic musculoskeletal, or nervous systems. The symptoms of CPPS appear to result from an interplay between psychological factors and dysfunction in the immune, neurological, and endocrine systems. The aim of this article was to present new insight about CPPS in order to raise awareness of nursing and medical staff in the identification and diagnosis of the syndrome and to promote an appropriate treatment for each woman who suffers from CPPS.

METHODS

A literature review about the factors associated with CPPS and therapeutic interventions for CPPS was conducted.

RESULTS

CPPS represents a chronic pain syndrome that combines anatomic malfunction of the pelvic floor muscles with malfunction of pain perception linked with psychological and cognitive factors.

CONCLUSIONS

The therapeutic interventions in CPPS cases should, consequently, follow a multidisciplinary approach.

Evaluation of sleep disorder and its effect on sexual dysfunction in patients with Fibromyalgia syndrome

Objective:

Sexual problems are commonly seen in women with fibromyalgia syndrome (FMS). The objective of this study was to reveal the relationship between the severity of symptoms, sleep disorder, and sexual dysfunction in women with FMS.

Materials and Methods:

A total of 140 sexually active women with FMS aged 17-67 years who presented to our physical medicine and rehabilitation outpatient clinic between January 2016 and June 2016 were enrolled in the study. The patients’ age, height, body weight, body mass index (BMI), and general pain score [visual analogue scale, (VAS)] for the last 1 week were recorded. The patients were given three different sets of questionnaires: the Pittsburgh Sleep Quality Index (PSQI), Fibromyalgia Impact Questionnaire (FIQ), and Female Sexual Function Index (FSFI).

Results:

The mean age of the patients was 40.3±8.5 years; the mean BMI was 27.1±4.4 kg/m², VAS (last 1 week) was 6.9±2 cm, the mean PSQI was 24.8±10.8 (one patient with PSQI ≤5), FIQ was 65.9±19.2, and FSFI was 19.0±6.9. No significant relationship was observed between the mean PSQI and BMI values (p=0.401), whereas a significant relationship was found between the mean values of VAS, FIQ, and FSFI (p=0.03; p=0.034; p<0.001, respectively). In Pearson’s correlation analysis, a positive correlation was noted between PSQI and VAS (r=0.324; p<0.001) and FIQ values (r=0.271; p=0.001). A significant relationship was found between the FIQ and VAS values (p<0.001). P less than 0.005 was considered statistically significant.

Conclusion:

Sleep disorder is regarded as the underlying cause for many signs and symptoms in FMS. Sexual dysfunction may develop in women with FMS, based on the severity of the disease and poor sleep quality. We found that sleep dysfunction was significantly related with the severity of disease, pain, and sexual disfunction. We also found a positive correlation between VAS and PSQI.
