leptin and Musculoskeletal-Pain

Musculoskeletal pain (MSP) has been recently linked with high plasma leptin levels. Our objective was to study if obese women, who have higher leptin levels, could have a higher frequency of MSP. We studied 6079 Latin-American women, 40-59 years old. Their epidemiological data were recorded and the Menopause Rating Scale (MRS), Golberg Anxiety and Depression Scale and Insomnia Scale were applied. MSP was defined as a score ≥2 on MRS11. Women with MSP were slightly older, had fewer years of schooling and were more sedentary. They also complained of more severe menopausal symptoms (29.2% versus. 4.4%, p < 0.0001). Furthermore, they had a higher abdominal perimeter (87.2 ± 12.0 cm versus 84.6 ± 11.6 cm, p < 0.0001) and a higher prevalence of obesity (23.1% versus 15.2%, p < 0.0001). Compared to normal weight women, those with low body weight (IMC <18.5) showed a lower risk of MSP (OR 0.71; 95%CI, 0.42-1.17), overweight women had a higher risk (OR 1.64; 95%CI, 1.44-1.87) and obese women the highest risk (OR 2.06; 95%CI, 1.76-2.40). Logistic regression analysis showed that obesity is independently associated to MSP (OR 1.34; 95%CI, 1.16-1.55). We conclude that obesity is one identifiable risk factor for MSP in middle-aged women.

Obesity's association with hand osteoarthritis cannot be fully explained by mechanical loading. We examined the relationship between adipokines and radiographic hand osteoarthritis severity and pain.. In a pilot study of 44 hand osteoarthritis patients (39 women and 5 men), serum adipokine concentrations and hand x-ray Kallman-scores were analyzed using linear regression models. Secondary analyses examined correlates of hand pain.. The cohort had a mean age of 63.5 years for women and 72.6 for men; mean (standard deviation) Kallman-scores were 43.3(17.4) for women and 46.2(10.8) for men. Mean body-mass-index was 30 kg/m(2) for women and men. Mean leptin concentration was 32.2 ng/ml (women) and 18.5 ng/ml (men); mean adiponectin-total was 7.9 ng/ml (women) and 5.3 ng/ml (men); mean resistin was 7.3 ng/ml (women) and 9.4 ng/ml (men). No association was found between Kallman-scores and adipokine concentrations (R(2) = 0.00-0.04 unadjusted analysis, all p-values>0.22). Secondary analyses showed mean visual-analog-scale pain of 4.8(2.4) for women and 6.6(0.9) for men. Leptin, BMI, and history of coronary artery disease were found to be associated with visual-analog-scale scores for chronic hand pain (R(2) = 0.36 unadjusted analysis, p-values≤0.04).. In this pilot study, we found that adipokine serum concentrations were not associated with hand osteoarthritis radiographic severity; the most important correlates of joint damage were age and disease duration. Leptin serum concentration, BMI, and coronary artery disease were associated with the intensity of chronic hand OA pain.
