Restrictive pulmonary deficit is associated with inflammation in suboptimally controlled obese diabetics
Caribbean data linking inflammation, pulmonary dysfunction and diabetes is unavailable. Spirometry, acanthosis nigricans, hs-CRP were assessed in 109 type 2 diabetics (43% males) mean age =55.6 years, BMI =29.29 kg/m2, waist circumference =103.86 cm. Residual FEV1/FVC increased with age (P=0.005), BMI (P=0.011) and waist circumference (P=0.003). Residual FVC related inversely to hs-CRP (–0.178), P<0.06) systolic (–0.028, P<0.031), diastolic (–0.247, P<0.010) pressure and weight (–0.25, P<0.009). Residual FEV1 related inversely to diastolic pressure (–0.219, P<0.023), hs-CRP (–0.234, P<0.015), acanthosis nigricans (–0.029, P<0.029). HbA1C and residual FEV1 predict high hs-CRP (P=0.011, P=0.046). Low FVC with inflammation presents in poorly controlled obese diabetics.
