Biomass Smoke Exposure

Objective: Asthma-chronic obstructive pulmonary disease overlap (ACO) indicates that its characteristics with pulmonary exaggerated reactivity and airflow limitation chronically. We aimed to investigate the differences among women non smoker participants who have asthma, chronic obstructive pulmonary disease (COPD) and ACO with biomass smoke exposure. Method: Patients were examined at the outpatient clinic from September 2017 to March 2020. Non-smoker women patients aged ≥40 years, diagnosed with obstructive pulmonary disease were included in the study. pulmonary function tests (PFT), early reversibility testing (bronchodilator test), and sputum eosinophil analysis were performed to all patients. Results: A total of 102 patients were included. The mean age was 46.95±9.50 years. In the differential diagnosis, 65 patients (63.7%) had asthma and 37 patients (36.3%) had COPD. Among COPD patients, 10 (27.0%) were diagnosed with ACO. The actual prevalence rates of COPD and ACO were 26.5% and 9.8%, respectively. Poisson regression analysis showed that COPD compared to asthma, while holding the others variable constant in the model, are expected to have 2.976 times greater rate for exacerbations.( IRR, 95%CI ,2.976 (0.687 to 1.494), 5.296 (1.203 to 2.130), P<0.001, Coef. 1.091, 1.667 respectively). Logistic Regression analysis demonstrated that, the count of sputum, blood eosinophil and total IgE results were correlated with the exacerbation times. Conclusion: Biomass smoke exposure in the women population is revealed as a significant factor for the diagnosis of ACO.

Biomass Smoke Exposure

Background: Chronic Obstructive Pulmonary Disease (COPD) is of public health importance. Indoor biomass (wood, cowdung etc) smoke exposure from cooking is associated with respiratory conditions and may predispose to COPD. The objective of this study was to evaluate the risk of biomass smoke exposure and COPD.Methods: A cross sectional study was conducted at a rural setting of Bangladesh. Rural women over 40 years and exposed to biomass fuel, liquid petroleum gas or natural gas smoke were evaluated using a questionnaire and their lung function was assessed using a portable spirometry.Results: The overall prevalence of COPD in the rural women was 20.4%. It was significantly higher in women using biomass fuel for cooking than in those using natural gas/LPG (p<0.001). Biomass smoke exposure was found significantly associated with COPD (OR= 3.385, CI=1.60-7.13, p<0.05). Lung function was significantly reduced (p<0.05) among women who were using biomass than those using natural gas/LPG.Conclusion: Biomass fuel smoke exposure is a risk factor for development of COPD.Chatt  Shi Hosp Med Coll J; Vol.15 (1); Jan 2016; Page 8-11

Inflammatory Profile

Background. Chronic obstructive pulmonary disease (COPD) is an inflammatory disease with predominant involvement of neutrophils, macrophages and CD8+ lymphocytes. Eosinophilic airway inflammations are reported in stable state and during acute exacerbations of tobacco smoke-associated COPD (TS-COPD). Women exposed to biomass fuel smoke are known to have eosinophils in sputum. However, little is known about the sputum cellular inflammatory profile in biomass fuel smoke-associated COPD (BMS-COPD). We therefore aimed to compare the sputum cellular inflammatory profile in tobacco smoke- and biomass smoke-associated COPD. Methods. The study was conducted in a tertiary care hospital in Goa, India. A total of 113 patients with stable COPD reporting to the outpatient pulmonary clinic were recruited. All participants were ≥ 40 years of age. Sputum induction studies were performed by the method of Pizzichini et al. after baseline subject characterization. Significant eosinophilia was defined as induced sputum eosinophils ≥ 3%. Results. There were 85 TS-COPD and 28 BMS-COPD patients. The mean age [standard deviation (SD)] was 64.7 (7.8) and 63.0 years (8.3), p = 0.32 in TS and BMS-COPD, respectively. Eighteen subjects (21.1%) were female smokers. The smoking pack-year median [interquartile range (IQR)] was 36 (20, 58) and hour-years of biomass smoke exposure mean (SD) was 192.4 (61). The TS-COPD and BMS-COPD cases showed a post-bronchodilator forced expiratory volume in one second (FEV1%) mean (SD) of 57.9 (17.1), and 62.6 (19.4), p= 0.22, respectively. Both groups had similar symptoms and severity of disease. Induced sputum total cell count per gram of sputum × 106 mean (SD) was 3.05 (1.53) for TS-COPD, and 2.55(1.37) for BMS-COPD p=0.12. The neutrophils % mean (SD) was 86.4 (16.5) and 87.9 (10.2), p = 0.64; eosinophils % median (IQR) was 2.5 (1, 10) and 8 (2, 12.8), p = 0.07; lymphocytes % median (IQR) was 0 (0, 0.75) and 0 (0, 1) p = 0.13; macrophages % median (IQR) was 2.5 (0.75, 5.7) and 1 (0, 4.7) p = 0.13; and significant eosinophilia (eosinophils ≥3%) was 42 (49.4%) and 20 (71%), p=0.04, for TS-COPD and BMS-COPD, respectively. Conclusions. For similar severity of disease and clinical symptoms, significant eosinophilic inflammation was observed in stable BMS-COPD, while both groups had similar neutrophilic inflammation.

Background: Skeletonized dissection of the internal thoracic artery (ITA) decreases the occurrence of sternal devascularization, thus decreasing the risk of postoperative sternal complications in patients undergoing bilateral ITA grafting. Methods: From April 1996 to July 1999, 1000 consecutive patients underwent bilateral skeletonized ITA grafting. Of the 770 male and 230 female patients, 420 were older than 70 years, and 312 had diabetes. Results: Operative mortality was 3.3%. Follow-up (4078 months) revealed 79 late deaths, and the Kaplan-Meier 6-year survival rate was 88%. Cox regression analysis revealed increased overall mortality (early and late) in patients with preoperative congestive heart failure (risk ratio [RR], 2.13; 95% confidence interval [CI], 1.31-3.45), in patients with peripheral vascular disease (RR, 5.52; 95% CI, 3.31-9.19), and in patients older than 70 years (RR, 2.18; 95% CI, 1.37-3.47). Early postoperative morbidity included sternal infection (2.2%), cerebrovascular accident (1.6%), and perioperative myocardial infarction (1%). Multiple regression analysis showed repeat operation (odds ratio [OR], 7.5; 95% CI, 1.77-31.6) and chronic obstructive pulmonary disease (OR, 3.6; 95% CI, 1.27-10.75) to be independent predictors of sternal infection. During follow-up, angina returned in 95 patients, 24 of whom required reintervention (20 cases of percutaneous balloon angioplasty and 4 reoperations). Postoperative coronary angiography performed in 87 patients revealed an ITA patency rate of 91%. Conclusions: Bilateral skeletonized ITA grafting is associated with satisfactory early and midterm results. We do not recommend the use of this surgical technique in patients with chronic obstructive pulmonary disease.

Objective We aimed to clarify the cognitive function of patients with chronic obstructive pulmonary disease (COPD) and different nutritional status. Methods Among 95 patients with COPD in this retrospective study, we administered the Nutritional Risk Screening 2002 (NRS 2002) and Mini-Mental State Examination (MMSE). We recorded patients’ clinical characteristics, comorbidities, and laboratory measurements. According to NRS 2002 scores, patients were divided into two groups: no nutritional risk with NRS 2002 < 3 ( n = 54) and nutritional risk, with NRS 2002 ≥ 3 ( n = 41). Results We found a negative correlation between NRS 2002 and MMSE scores in participants with COPD ( r = −0.313). Patients with nutritional risk were more likely to be cognitively impaired than those with no nutritional risk. Multivariate logistic regression analysis indicated that malnutrition was an independent risk factor for cognitive impairment, after adjusting for confounders (odds ratio [OR] = 4.120, 95% confidence interval [CI]: 1.072–15.837). We found a similar association between NRS 2002 and MMSE scores at 90-day follow-up using a Pearson’s correlation test ( r = −0.493) and logistic regression analysis (OR = 7.333, 95% CI: 1.114–48.264). Conclusions Patients with COPD at nutritional risk are more likely to have cognitive impairment.

Rationale. Exposure to biomass smoke (BMS) has been implicated in chronic obstructive pulmonary disease (COPD). About 3 billion people worldwide use biomass fuel for cooking and heating. Women in rural communities of low- and lower-middle-income countries are disproportionately exposed to massive amounts of BMS during active cooking hours (4–6 h/day). Therefore, BMS exposure is considered as a risk factor for COPD in the same order of magnitude as tobacco smoke. In rural India, due to cultural reasons, women are the primary cook of the family and are mostly nonsmokers. Thus, BMS-induced COPD is predominant among rural Indian women. However, BMS-COPD remains a relatively unexplored health problem globally. Therefore, we investigated the serum chemokine and cytokine signatures of BMS-COPD and tobacco smoke-induced COPD (TS-COPD) patients compared to their control in a rural South Indian population for this field study. Methods. Concentrations of 40 serum chemokines and cytokines were measured using a multiplexed immunoassay. The study cohort consisted of BMS-COPD (female; n=29) and BMS-exposed subjects without COPD (BMS-CONTROL; female; n=24). For comparison, data from TS-COPD patients (male, n=23) and tobacco smokers without COPD (TS-CONTROL; male, n=22) were investigated. Subjects were matched for age, sex, and biomass exposure. Tobacco consumption was slightly higher in TS-COPD subjects compared to TS-CONTROL. BMS-exposed and TS-exposed subjects (currently exposed) were from the same locality with similar dwelling habits and socioeconomic status. A validated structured questionnaire-based survey and spirometry was performed. An additional control group with no tobacco and BMS exposure (TS-BMS-CONTROL; n=15) was included. Statistical significance was set at p≤0.01. Results. Serum median concentrations (pg/ml) of CCL15 [8799.35; 5977.22], CCL27 [1409.14; 1024.99], and CXCL13 [37.14; 26.03] were significantly higher in BMS-CONTROL compared to BMS-COPD subjects. Nine analytes exhibited higher concentrations in TS-CONTROL compared to TS-COPD subjects. Comparison of chemokine and cytokine concentrations among BMS-COPD versus TS-COPD and BMS-CONTROL versus TS-CONTROL subjects also revealed distinct molecular signatures. Conclusion. Our data identifies CCL27 and CXCL13 as putative, plausibly homeostatic/protective biomarkers for BMS-COPD within the investigated population that warrants validation in larger and multiple cohorts. The findings further indicate exposure-specific systemic response of chemokines and cytokines.
