Endometriosis as a Comorbid Condition in Chronic Fatigue Syndrome (CFS): Secondary Analysis of Data From a CFS Case-Control Study

Abstract:

Background: Endometriosis (EM) is a recognized co-morbid condition in women with chronic fatigue syndrome (CFS). This analysis evaluates the impact of EM on the health of women with CFS by comparing selected health characteristics and laboratory parameters in women with CFS with and without EM (CFS+EM and CFS-only).

Methods: This secondary analysis included all 36 women with CFS from a cross-sectional study of CFS in Wichita, KS, conducted between 2002 and 2003. The health characteristics and laboratory parameters of interest included functioning, fatigue, CFS-related symptoms, gynecologic history, routine laboratory parameters, inflammatory markers, cortisol levels, allostatic load, and sleep parameters (overnight polysomnography). We used parametric or non-parametric tests to compare group differences in the selected health characteristics and laboratory parameters. For examining the association between EM and variables of interest, logistic regression models were performed and odds ratios (OR) with 95% confidence intervals (CI) were reported for the magnitude of associations. Statistical significance was set at 0.05 (two-sided).

Results: The mean age of this study sample was 50.9 years. Of women with CFS, 36.1% reported having EM. Age and body mass index (BMI) did not differ between CFS+EM and CFS-only groups. When examining the impact of EM, compared to women with CFS-only, women with both CFS and EM were more likely to report chronic pelvic pain [OR = 9.00 (95% CI, 1.47-55.25)] and hysterectomy [OR = 10.3 (1.82-58.39)], had more CFS symptoms (6.8 ± 0.3 vs. 5.5 ± 0.3, p = 0.02), younger mean age at menopause onset (36.4 ± 3.0 vs. 47.0 ± 2.7 years, p = 0.03), higher mean number of obstructive apnea episodes per hour (20.3 vs. 4.4, p = 0.05) and reported more negative life events (15.8 vs. 4.4, p = 0.05). Other parameters did not differ significantly between the two groups.

Conclusions: We found more than a third of women with CFS reported endometriosis as a comorbid condition. The endometriosis comorbidity was associated with chronic pelvic pain, earlier menopause, hysterectomy, and more CFS-related symptoms. However, endometriosis in women with CFS did not appear to further impact functioning, fatigue, inflammatory markers, or other laboratory parameters. Further investigations including younger women are warranted.

Link between early menopause, chronic fatigue syndrome discovered

A newfound link between chronic fatigue syndrome (CFS) and early menopause was reported online today in Menopause, the journal of The North American Menopause Society (NAMS). This link, as well as links with other gynecologic problems and with pelvic pain, may help explain why CFS is two to four times more common in women than in men and is most prevalent in women in their 40s. Staying alert to these problems may also help healthcare providers take better care of women who may be at risk for CFS, say the authors of this population-based, case-control study.

Based on a long-term study of CFS and fatiguing illnesses in Georgia, this analysis from Centers for Disease Control scientists included 84 women with CFS and 73 healthy control women who completed detailed gynecologic history questionnaires. Striking differences emerged from the comparison between those groups.

The women with CFS were some 12 times more likely to have pelvic pain that wasn’t related to menstruation (such as pelvic floor dysfunction, interstitial cystitis/painful bladder syndrome or IC/PBS, and irritable bowel syndrome) than the control women. The women with CFS also reported excessive bleeding (74% vs 42%) much more often as well as significantly more bleeding between periods (49% vs 23%) and missing periods (38% vs 22%). In addition, they used hormones for purposes other than contraception (such as to treat irregular periods, menopausal symptoms or bone loss) much more often (57% vs 26%).

Also striking, most women with CFS–66%–had undergone at least one gynecologic surgery, compared with only 32% of controls, most commonly hysterectomy (55% versus 19%). Women with CFS underwent menopause early (at or before age 45) because of hysterectomy much more often (62% vs 33%). (Surgical menopause occurs immediately when both ovaries are removed at hysterectomy and often prematurely even when ovaries are preserved.) Bleeding as the reason for hysterectomy was significantly more common in the women with CFS. They also underwent natural menopause earlier, but the numbers were too small to show a significant difference.

Although CFS has previously been linked with pelvic pain and gynecologic conditions such as endometriosis, IC/PBS, polycystic ovaries, and menstrual abnormalities, this is the first study to show a link with early menopause. Sex hormone abnormalities or their early decrease or disappearance may underlie these links, and the authors called for more research to find out whether they do play a role in causing or perpetuating CFS in some women. But meanwhile, they emphasized, women’s healthcare providers need to stay alert for symptoms of CFS, such as sleep or memory problems, muscle and joint pain, and worse symptoms after exertion, developing in women who have these gynecologic or pelvic pain problems.

“CFS can take a tremendous toll on women’s lives at midlife and on our society and healthcare system. Being aware of the association of CFS and earlier menopause can help providers assist women in sorting out symptoms of CFS from symptoms of menopause,” says NAMS Executive Director Margery Gass, MD, NCMP. This paper also raises the chicken and egg question: Is early menopause the cause of later health problems or simply the result of earlier health problems not recognized as the cause of early menopause?

Early menopause and other gynecologic risk indicators for chronic fatigue syndrome in women

Abstract:

OBJECTIVE: This study aims to examine whether gynecologic conditions are associated with chronic fatigue syndrome (CFS).

METHODS: This study includes a subset of 157 women from a population-based case-control study in Georgia, United States, conducted in 2004-2009. Gynecologic history was collected using a self-administered questionnaire. Crude odds ratios (ORs) with 95% CIs and ORs adjusted for body mass index and other covariates, where relevant, were estimated for gynecologic conditions between 84 CFS cases and 73 healthy controls.

RESULTS: Cases and controls were of similar age. Women with CFS reported significantly more gynecologic conditions and surgical operations than controls: menopause status (61.9% vs 37.0%; OR, 2.37; 95% CI, 1.21-4.66), earlier mean age at menopause onset (37.6 vs 48.6 y; adjusted OR, 1.22; 95% CI, 1.09-1.36), excessive menstrual bleeding (73.8% vs 42.5%; adjusted OR, 3.33; 95% CI, 1.66-6.70), bleeding between periods (48.8% vs 23.3%; adjusted OR, 3.31; 95% CI, 1.60-6.86), endometriosis (29.8% vs 12.3%; adjusted OR, 3.67; 95% CI, 1.53-8.84), use of noncontraceptive hormonal preparations (57.1% vs 26.0%; adjusted OR, 2.95; 95% CI, 1.36-6.38), nonmenstrual pelvic pain (26.2% vs 2.7%; adjusted OR, 11.98; 95% CI, 2.57-55.81), and gynecologic surgical operation (65.5% vs 31.5%; adjusted OR, 3.33; 95% CI, 1.66-6.67), especially hysterectomy (54.8% vs 19.2%; adjusted OR, 3.23; 95% CI, 1.46-7.17). Hysterectomy and oophorectomy occurred at a significantly younger mean age in the CFS group than in controls and occurred before CFS onset in 71% of women with records of date of surgical operation and date of CFS onset.

CONCLUSIONS: Menstrual abnormalities, endometriosis, pelvic pain, hysterectomy, and early/surgical menopause are all associated with CFS. Clinicians should be aware of the association between common gynecologic problems and CFS in women. Further work is warranted to determine whether these conditions contribute to the development and/or perpetuation of CFS in some women.
