Abstract Background T helper (Th) cell cytokine imbalances have been associated with the pathophysiology of chronic obstructive pulmonary disease (COPD), including the Th1/Th2 and Th17/Treg paradigms. Clarifying cytokine profiles during COPD acute exacerbation (AE) and their relationships with clinical manifestations would help in understanding the pathogenesis of disease and improve clinical management.Methods Patients admitted to the hospital with AEs of COPD from January 2017 to August 2017 were included in this study, and follow-up was conducted after discharge (every 30 days, for a total of 120 days). Sputum samples of patients at different time points (including at admission, discharge, and follow-up) were collected, and sputum cytokine profiling (12 cytokines in total) was performed using a Luminex assay. Clinical data of patients were collected by a unified electronic medical record form.Results A total of 87 patients with COPD were enrolled, aged 72 ± 8.5 years, among whom 1, 12, 32, and 42 cases exhibited GOLD stage I, II, III, and IV, respectively. According to the cytokine profiles at admission, patients were divided into three clusters by a k -means clustering algorithm, namely, Th1 high Th17 high (n=26), Th1 low Th17 low (n=56), and Th1 high Th17 low (n=5), which revealed distinct clinical characteristics. Patients with Th1 high Th17 low profile had a significantly longer length of non-invasive ventilation time and length of hospital stay than patients with Th1 high Th17 high profile (7 vs. 0 days, 22 vs. 11 days, respectively, p < 0.05), and had the highest AE frequency. Sputum levels of Th17 cytokines (IL-17A, IL-22, and IL-23) during AE were negatively correlated with AE frequency in the last 12 months ( r = -0.258, -0.289 and -0.216, respectively, p < 0.05). Moreover, decreased sputum IL-17A levels were independently associated with increased AE frequency, whith an OR (95% CI) of 0.975 (0.958 - 0.993) and a p = 0.006.Conclusion Th1/Th17 imbalance during AE is associated with the severity of COPD. Decreased Th17 cytokine expression is correlated with increased AE frequency. The Th1/Th17 balance may be a specific target for the therapeutic manipulation of COPD.Trial registration: ClinicalTrials.gov ID: NCT03236480.

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.

Background: The aim of this study was to investigate whether physical activity, sarcopenia, and anemia are associated an with increased risk of tuberculosis (TB) among the older population. Methods: We included 1,245,640 66-year-old subjects who participated in the National Screening Program for Transitional Ages for Koreans from 2009 to 2014. At baseline, we assessed common health problems in the older population, including anemia and sarcopenia. The subjects’ performance in the timed up-and-go (TUG) test was used to predict sarcopenia. The incidence of TB was determined using claims data from the National Health Insurance Service database. Results: The median follow-up duration was 6.4 years. There was a significant association between the severity of anemia and TB incidence, with an adjusted hazard ratio (aHR) of 1.28 [95% confidence interval (CI), 1.20–1.36] for mild anemia and 1.69 (95% CI, 1.51–1.88) for moderate to severe anemia. Compared with those who had normal TUG times, participants with slow TUG times (⩾15 s) had a significantly increased risk of TB (aHR 1.19, 95% CI, 1.07–1.33). On the other hand, both irregular (aHR 0.88, 95% CI 0.83–0.93) and regular (aHR 0.84, 95% CI, 0.78–0.92) physical activity reduced the risk of TB. Male sex, lower income, alcohol consumption, smoking, diabetes, and asthma/chronic obstructive pulmonary disease increased the risk of TB. Conclusion: The risk of TB among older adults increased with worsening anemia, sarcopenia, and physical inactivity. Physicians should be aware of those modifiable predictors for TB among the older population.

Introduction: Chronic obstructive pulmonary disease (COPD) affects approximately 174 million people worldwide.The objective was to determine the trends of the use of medications for COPD in a group of Colombian patients. Methods: This was a retrospective study on prescription patterns of bronchodilators and other medications used in COPD from a population database with follow-up at 12 and 24 months. Patients older than 18 years of age of any sex who had COPD between 2017 and 2019 were included. Sociodemographic variables, medications, treatment schedules for COPD, comorbidities, comedications, and the specialty of the prescriber were considered. Results: A total of 9,476 people with a diagnosis of COPD were evaluated. They had a mean age of 75.9 ± 10.7 years, 50.1% were men, and 86.8% were prescribed by a general practitioner. At the beginning of the follow-up, on average, they received 1.6 medications/patient, mainly short-acting antimuscarinics (3784; 39.9%), followed by short-acting β-agonists (2997, 31.6%) and inhaled corticosteroids (ICS) (2239, 23.6%), but 5083 (53.6%) patients received a long-acting bronchodilator. At the beginning of the follow-up, 645 (6.8%) patients were put on triple therapy with antimuscarinics, β-agonists, and ICS, and at 12 months, this rose to 1388 (20.6%). A total of 57.9% had comorbidities, most often hypertension (44.4%). Conclusions: This group of patients with COPD treated in Colombia frequently received short-acting bronchodilators and ICS, but a growing proportion are undergoing controlled therapy with long-acting bronchodilators, a situation that can improve the indicators of morbidity, exacerbations, and hospitalization.

BackgroundIndividual susceptibility to exacerbations in chronic obstructive pulmonary disease (COPD) is likely influenced by genetic factors; however, most such variance is unexplained. We hypothesised that β2-adrenergic receptor genotypes, Gly16Arg (rs1042713, c.46G>A) and Gln27Glu (rs1042714, c.79C>G) influence risk of severe exacerbations in COPD.MethodsAmong 96 762 individuals in the Copenhagen General Population Study, we identified 5262 with COPD (forced expiratory volume in one second divided by forced vital capacity, FEV1/FVC, below 0.7, FEV1 less than 80% of predicted value, age above 40 years and no asthma) who had genotyping performed. Severe exacerbations were defined as acute admissions due to COPD during 5 years of follow-up (mean 3.4 years). 923 individuals with COPD diagnosed similarly in the Copenhagen City Heart Study (CCHS) were used for replication analyses.ResultsWe recorded 461 severe exacerbations in 5262 subjects. The HRs for severe exacerbations were 1.62 (95% CI 1.30 to 2.03, p=0.00002) for 16Gly/Arg heterozygotes and 1.41 (1.04 to 1.91, p=0.03) for 16Arg homozygotes, compared with 16Gly homozygotes. HRs were 1.35 (1.03 to 1.76, p=0.03) for 27Gln/Glu heterozygotes and 1.49 (1.12 to 1.98, p=0.006) for 27Gln homozygotes, compared with 27Glu homozygotes. Similar trends were observed in the CCHS. Among 27Gln homozygotes only, HRs were 5.20 (1.81 to 14.9, p=0.002) for 16Gly/Arg heterozygotes and 4.03 (1.40 to 11.6, p=0.01) for 16Arg homozygotes, compared with 16Gly homozygotes.ConclusionCommon β2-adrenergic receptor genotypes influence risk of severe exacerbations in COPD, potentially mainly by genetic influence of the 16Arg allele in rs1042713.

Alpha-1 antitrypsin (AAT) deficiency is a clinically under recognized inherited disorder. The main clinical manifestations relate to three separate organs: the lung, the liver, and the skin. In the lung, severe deficiency of AAT predisposes to chronic obstructive pulmonary disease. We present a case of 34 years male with a history of recurrent chest infections in past and treated in the line of bronchial asthma but not relieved. He was admitted on 22nd May 2011 at BPKIHS. He presented with type 2 respiratory failure and had features of severe pulmonary arterial hypertension and left lower lobe pneumonia. The patient got improved with the treatment and is doing well on follow up. The diagnosis should be strongly suspected in patients with history suggestive of bronchial asthma and with obstructive features.Journal of Advances in Internal Medicine 2014;3(2):65-67
