TC2C USE OF CANNABIS IN A EAST-LONDON FIRST EPISODE PSYCHOSIS SAMPLE: DATA FROM THE GAP — GENETICS AND PSYCHOSIS — STUDY

Weight loss and muscle wasting are common features reported in COPD patients and they are all related with systemic inflammation. In this study, the relationship between pulmonary functions and inflammatory and metabolic parameters in low weight COPD patients were investigated.Fifty male COPD patients were grouped according to the Global Initiative for Chronic Obstructive Lung Disease criteria. Group 1: Mild–moderate COPD patients (n = 18; with a mean age of 66.4 ± 9.2 yrs; body mass index (BMI):19.7 ± 1.5 kg/m2), group 2: Severe–very severe COPD patients (n = 32; with a mean age of 65.9 ± 10.0 yrs; BMI:19.3 ± 1.6 kg/m2), group 3: Control group composed of healthy nonsmoking males (n = 17; with a mean age of 50.2 ± 8.4 yrs; BMI:21.85 ± 1.5 kg/m2). Anthropometric parameters, serum levels of adiponectin (ApN), ghrelin, leptin, hsCRP, IL-6, IL-1β, IL-8, TNF-α and pulmonary functions were compared.Adiponectin concentration was higher in group 1 (43.3 ± 28.6 ng/mL; p < 0.05) and group 2 (59.9 ± 31.8 ng/mL; p < 0.001) when compared with the control group (23.5 ± 13.6 ng/mL). Ghrelin concentrations were higher in COPD groups (1281.0 ± 1173.7 and 1840.0 ± 403.6 pg/mL; p < 0.05) compared to the control subjects (554.0 ± 281.9 pg/mL). When the groups were compared, no significant difference was found for leptin, IL-1β, TNF-α, and IL-8. Interleukin-6 and hsCRP levels were higher in group 1 than in the control group. ApN was negatively correlated with BMI and FEV1. In all groups, FEV1 showed positive correlation with BMI, skinfold thicknesses, insulin and triglyceride; negative correlation with age, pack/years, HDL-Chol and ApN.Increased SHBG with decreased insulin level and HOMA-IR may indicate increased insulin sensitivity in COPD groups.The anti-inflammatory effect of ApN and ghrelin is more evident in severe–very severe COPD patients.
