【 摘 要 】

Background: Osteoporosis, sarcopenia, pulmonary hypertension are common with COPD. There are only few studies which have evaluated the relationship of these co-morbidities with COPD severity.Aim: To study osteoporosis in terms of bone mineral density (BMD) and sarcopenia in terms of fat free mass index (FFMI) with dual energy x-ray absorptiometry (DEXA); and their relation with forced expiratory volume in one second (FEV1%). To study relation of pulmonary hypertension (PH) with forced expiratory volume in 1 second (FEV1) and BODE index in COPD.Materials and Methods: In 30 stable COPD patients, BMD and FFMI were calculated with DEXA scan. Two groups of FEV1 ?50% and FEV1<50% and three groups of BODE index <5, 5-6 and ?7 were compared with PH severity.Results: All patients had low BMD (33% osteopenia & 66% osteoporosis) and 83.3% had sarcopenia. Chi-square test to assess the significance of osteoporosis and sarcopenia in relation to FEV1 groups was statistically insignificant (p value=0.88).5/7 had normal pulmonary artery pressure (PAP) and 2 had mild PH in group I i.e. FEV1 ?50%, whereas in group II i.e. FEV1<50 %, 2 had normal PAP; 15, 3 and 2 had mild, moderate and severe PH respectively. Binary logistic regression to assess PH in relation to FEV1 and BODE index showed odds ratio for FEV1 ? 50% statistically significant (p value= 0.016).Conclusion: Osteoporosis and sarcopenia are very common in COPD in Indian population but there is no correlation with FEV1. Though BODE index is a good prognostic indicator, FEV1 is more likely to correlate with severity of PH than BODE index.
