According to findings published in Pain Medicine, sulfated dehydroepiandrosterone (DHEA-S) concentrations in blood serum were reduced among women with chronic pain.

For this study, participants (N=1216) provided blood samples between 6:00 and 8:00 AM following an overnight fast and were surveyed about symptoms of chronic pain.

Of the participants, 57% were women; 43.6% of the men and 44.0% of the women were aged 50 to 64 years; 79.0% of the men and 71.4% of the women were white, and 47.4% of the men and 38.2% of the women had a bachelor’s degree or higher. More of the women – 37% – reported chronic pain than the men, 34%.

Among men, serum DHEA concentrations did not differ on the basis of chronic pain status (4.83 vs 4.79 ng/mL; P =.87), and neither did DHEA-S levels (107.7 vs 110.0 mg/dL; P =.74). Women with chronic pain had DHEA levels of 4.23 ng/mL and DHEA-S levels of 54.6 mg/dL which were significantly lower than women without chronic pain (5.04 ng/mL; P =.002; 68.6 mg/dL; P <.001).

DHEA-S was significantly associated with pain status among women (b, -0.072; 95% CI, -0.127 to -0.017; P =.010) and remained significant after adjusting for medication use, lag time, and symptoms of depression (b, -0.076; 95% CI, -0.132 to -0.021; P =.007). DHEA was not significantly associated with pain status among women (b, -0.038; 95% CI, -0.086 to 0.011; P =.13).

With a continuous linear analysis, number of pain locations (DHEA: b, -0.046; 95% CI, -0.078 to -0.014; P =.0005; DHEA-S: b, -0.059; 95% CI, -0.095 to -0.022; P =.002) and degree of interference (DHEA: b, -0.014; 95% CI, -0.027 to -0.001; P =.034; DHEA-S: b, -0.026; 95% CI, -0.041 to -0.012; P <.001) were significantly associated among women.

Chronic pain explained 29.3% of the variance observed for DHEA among women and 28.9% of the DHEA-S variance. Additional predictors for DHEA among women were age (b, -0.010; P <.001), use of opioid medication (b, -0.149; P <.001), black race (b, -0.094; P =.002), use of lipid-lowering medication (b, -0.067; P =.013), and constipation (b, -0.083; P =.050).

Additional predictors for DHEA-S among were age (b, -0.010; P <.001), black race (b, -0.108; P =.001), use of opioid medication (b, -0.145; P =.002), current use of female hormone (b, -0.083; P =.013), thyroid hormone levels (b, -0.092; P =.014), use of antihypertensive medication (b, -0.066; P =.022), autoimmune disorder (b, -0.228; P =.026), moderate alcohol consumption (b, 0.057; P =.030), and use of antidiabetic medication (b, 0.097; P =.039).

Comparing sexes, the sex-specific coefficients differed significantly (DHEA:b, -0.062; P =.046; DHEA-S: b, -0.073; P =.041).

This study was limited by its cross-sectional design, in which causal relationships could not be tested.

These data indicated that DHEA or DHEA-S may be biomarkers for chronic pain among women. Future studies are needed to determine whether DHEA supplementation could provide an effective pain therapeutic.
