Purpose: Co-morbidities are common in chronic obstructive pulmonary disease (COPD) and are associated with increased morbidity and mortality. The aim of the present study was to explore the prevalence of several comorbid conditions in severe COPD, and to investigate and compare their associations with long-term mortality.
Methods: In May 2011 to March 2012, 241 patients with COPD stage 3 or 4 were included in the study. Information was collected on sex, age, smoking history, weight and height, current pharmacological treatment, number of exacerbations the recent year and comorbid conditions. At December 31st, 2019, mortality data (all-cause and cause specific) were collected from the National Cause of Death Register. Data were analyzed using Cox-regression analysis with gender, age, previously established predictors of mortality and comorbid conditions as independent variables, and all-cause mortality and cardiac and respiratory mortality, respectively, as dependent variables.
Results: Out of 241 patients, 155 (64%) were deceased at the end of the study period; 103 patients (66%) died of respiratory disease and 25 (16%) of cardiovascular disease. Impaired kidney function was the only comorbid condition independently associated with increased all-cause mortality (HR (95% CI) 3.41 (1.47-7.93) p=0.004) and respiratory mortality (HR (95%CI) 4.63 (1.61 to 13.4), p = 0.005). In addition, age ≥70, BMI <22 and lower FEV1 expressed as %predicted were significantly associated with increased all-cause and respiratory mortality.
Conclusion: In addition to the risk factors high age, low BMI and poor lung function; impaired kidney function appears to be an important risk factor for mortality in the long term, which should be taken into account in the medical care of patients with severe COPD.

Purpose: When first-line chronic rhinosinusitis (CRS) treatment fails, patients can either be treated with oral or injected systemic corticosteroids. Although the EPOS and international guidelines for CRS do not mention injected corticosteroids, it is commonly used by ear, nose, and throat specialists. While the risks of systemic corticosteroids, in general, are known, the pros and cons of injected and oral corticosteroids (OCS) in CRS treatment are unclear.
Methods: A systematic review of studies that report the effects and/or side effects of injected and oral corticosteroids in the treatment of CRS was made according to the PRISMA guidelines.
Results: Altogether, 48 studies were included, only five studies reported on injected corticosteroids, and five attended with side effects. Three studies found beneficial effects of OCS perioperatively on sinus surgery, while four articles found no effect. Nineteen articles reported that OCS resulted in an improvement in symptoms. Two articles presented a longer-lasting effect of injected corticosteroids than OCS. Three studies reported adverse side effects of systemic corticosteroids, while two studies showed no adverse side effects. One study showed less adrenal suppression after injected corticosteroids compared to OCS. The evidence is not strong but shows a positive effect of systemic corticosteroids that lasts longer with injections.
Conclusion: Although systemic corticosteroids are widely used to treat CRS, there is a lack of studies comparing the OCS and injected corticosteroids. The evidence is sparse, however, injected steroids show longer effects with fewer side effects. An RCT study is needed to compare OCS and injected corticosteroids.

Objective: To evaluate if high-intensity interval training three times weekly for 12 weeks improves asthma control in overweight, postmenopausal women with uncontrolled, late-onset asthma.
Methods: The reported study is a randomized clinical pilot study (www.clinicaltrials.gov; NCT03747211) that compared 12 weeks of high-intensity interval training (spinning) with usual care. The five-question Asthma Control Questionnaire (ACQ-5) was used as primary outcome. Secondary measures included systemic inflammation and inflammation of the airways, body composition, and cardiac function during exercise.
Results: We included 12 women with asthma (mean age 65 years (SD 6); mean body mass index 30 kg/m2 (SD 2)) from whom eight were randomized to exercise and four to control. Baseline ACQ-5 was 1.95 (SD 0.53) in the control group and 2.03 (0.54) in the exercise group. Patients had a mean blood eosinophil level of 0.16 × 109cells/L (SD 0.07) and a mean fraction of exhaled nitric oxide of 23 ppb (SD 25). Mixed models showed that participants in the exercise group reduced their ACQ-5 by 0.55 points (95%CI -1.10 to -0.00; P = 0.08) compared with the control group. The exercise group significantly reduced their mean body fat percentage (-2.7%; 95%CI -4.5 to -0.8; P = 0.02), fat mass (-2.8 kg; 95%CI -5.1 to -0.4; P = 0.044) and android fat mass (-0.33 kg; 95%CI -0.60- -0.06; P = 0.038). In analyses of cardiac measures, we saw no significant effects on right ventricular function (fractional area change), diastolic function or left ventricular function.
Conclusions: Although changes in ACQ-5 were slightly insignificant, these preliminary findings indicate that aerobic exercise training can be used as a means to improve asthma control in overweight, postmenopausal women with asthma.

Objectives: For patients admitted with an acute exacerbation of COPD (AECOPD) and a need for supplementary oxygen therapy, to determine if peripheral oxygen saturation < 88% (hypoxemia) or >92% (hyperoxemia), within first 24 hours of admission, is associated with 'treatment failure' or fewer days alive and out of hospital within 14 days after admission.
Design: A retrospective multicenter observational study, reviewing consecutive data on SpO2, oxygen, and drug administration at three predefined time points, on adverse events in patients admitted with COPD between December 2019 and June 2020. Multivariable logistic regression analysis, Mann Whitney U- and Chi-square-test were used.
Setting: Acute hospital setting, across four different hospitals in the capital region of Denmark.
Participants: Patients with a confirmed diagnosis of COPD admitted with an acute exacerbation and an oxygen need within the first 24 hours admission.
Results: In total 289 COPD patients were included. The median age was 74.8 years [interquartile range (IQR):69.6 to 81.8], 191 were female and 132 patients experienced 'treatment failure'. A minimum of one episode of hypoxemia (SpO2 < 88%) within first 24 hours was associated with having a low number (≤4) of days alive and out of hospital within 14 days after admission: OR 2.4 (95%CI 1.2 to 4.8), p = 0.02, absolute risk 44% vs. 26% p = 0.01, Chi-square. Comparable results were observed after 30 days of follow-up: OR 2.6 (95% CI 1.0 to7.1), p = 0.05. A minimum of one measurement of hyperoxemia (SpO2 > 92%), within first 24 hours of admission was not associated with low number of days alive and out of hospital within 14 days OR 1.0 (95% CI 0.5 to 2.1) nor at 30 days.
Conclusion: For admitted patients with AECOPD, being hypoxemic ever within the first 24 hours after admission is associated with a substantially increased risk of a poor prognosis.

Background: Lung cancer patients undergoing treatment with immune checkpoint inhibitors (ICIs) are at risk of developing immune-related (ir-)pneumonitis. Since lung cancer patients have competing reasons for respiratory symptoms, this poses a diagnostic challenge. This study aimed to explore diagnosis and management of ir-pneumonitis in this patient group.
Materials and methods: Suspected ir-pneumonitis was frequent in this group of patients. The cohort was characterized by high heterogeneity and lack of unequivocal diagnostic conclusions. Treatment of ir-pneumonitis was longer than recommended and involvement of pulmonologist was very infrequent. The result of this study reflects the difficulties in a daily clinical setting to diagnose and manage patients with lung cancer presenting with pulmonary symptoms.

Introduction: Long-term High Flow Nasal Cannula (LT-HFNC), defined as High Flow Nasal Cannula treatment provided to patients with chronic pulmonary conditions during stable phases, has emerged as a home treatment in different categories of patients with chronic lung diseases in recent years.
Methods: This paper summarizes the physiological effects of LT-HFNC and evaluates the clinical knowledge to date about treatment in patients with chronic obstructive lung disease, interstitial lung disease and bronchiectasis. The guideline is translated and summarized in this paper and presented unabridged as an appendix to the paper.
Results: The paper describes the working process behind the Danish Respiratory Society's National guideline for treatment of stable disease, which has been written to support clinicians in both evidence-based decision making and practical issues concerning the treatment.

Background: Invasive pneumococcal disease (IPD) is a major cause of morbidity and mortality globally. However, the literature on the vaccine effectiveness (VE) of 23-valent polysaccharide vaccine (PPV23) and 13-valent conjugated vaccine (PCV13) against IPD in adults is sparse. The aim was to summarize the available evidence on the VE of the PPV23 and the PCV13 in elderly individuals against IPD and to investigate how age and comorbidities influence VE against IPD.
Methods: A systematic search was conducted in Medline and Embase in February 2021. We used combinations of terms related to PPV23, PCV13, elderly, high-risk populations, and IPD. Eligible articles published since 2010 were included. Two authors reviewed and extracted data.
Results: Eight studies met the inclusion criteria for PPV23. The meta-analysis showed a reduced OR for all-type IPD with the use of PPV23 vaccine compared with unvaccinated controls (OR 0.69; 95%CI 0.54, 0.88) and a reduced OR for vaccine-type IPD compared with non-vaccine type IPD (0.69; 95%CI 0.63, 0.76). VE against vaccine-type IPD ranged from 28% to 54.1% for individuals aged 65-79 and from 7.5% to 34% for those aged ≥80-85 years. Most studies found a lower VE of PPV23 in populations with comorbidities and in immunocompromised populations compared with the VE for individuals without comorbidities.One study met the inclusion criteria for PCV13. The vaccine efficacy of PCV13 against IPD in individuals aged ≥65 was 75.0% (95% CI, 41.4 to 90.8).
Conclusion: The results from this review show a reduction of IPD in elderly and high-risk populations vaccinated with PPV23 and PCV13. The protective effect may be lower in elderly individuals aged >80 and in individuals with comorbidities. However, the literature is sparse; large-scale prospective studies are required to evaluate the VE of PPV23 and PCV13 vaccination in adults against IPD.

Background: Sedating antihistamines such as promethazine are used as anxiolytics and hypnotic agents for patients with chronic obstructive pulmonary disease (COPD) with and without asthma despite limited knowledge of its effects and side effects. We evaluated if treatment with promethazine had a lower risk of harmful outcome.
Methods: Nationwide retrospective cohort study of Danish specialist diagnosed outpatients with COPD treated with promethazine or an active comparator (melatonin). Patients with collection of promethazine or melatonin were propensity score matched 1:1. The primary outcome was a composite of severe COPD exacerbations and death from all causes analyzed by Cox proportional hazards regression. We performed an interaction analysis for comorbid asthma.
Results: In our registry of 56,523 patients with COPD, 5,661 collected promethazine (n = 3,723) or melatonin (n = 1,938). A cohort of 3,290 promethazine- or melatonin-treated patients matched 1:1 was available for the primary analysis.Within 1-year patients treated with promethazine were at higher risk of the primary outcome than matched controls with a Hazard Ratio (HR) of 1.42 (CI 1.27-1.58, p < 0.0001). Similarly, the risk of death was higher for promethazine-treated patients (HR 1.53, CI 1.32-1.77, p < 0.0001). An interaction analysis for comorbid asthma showed no interaction between comorbid asthma and the likelihood of a primary outcome when collecting promethazine (p = 0.19). Adjusted Cox analysis on the entire population indicated a further increased risk with more promethazine (HR for primary outcome among patients collecting ≥ 400 promethazine tablets/year=2.15, CI 1.94-2.38, p<0.0001).
Conclusions: Promethazine-treated patients with COPD had a concerning excess risk of a composite outcome of severe exacerbations and death from all causes compared to melatonin.
背景:镇静抗组胺药如异丙嗪被用作慢性阻塞性肺疾病(COPD)伴或不伴哮喘患者的抗焦虑药和催眠药,尽管对其作用和副作用的了解有限。我们评估异丙嗪治疗是否有较低的有害后果风险。方法:在全国范围内对丹麦专家诊断的门诊COPD患者进行回顾性队列研究,这些患者使用异丙嗪或活性比较物(褪黑激素)治疗。收集异丙嗪或褪黑素的患者倾向评分为1:1匹配。通过Cox比例风险回归分析,主要结局是严重COPD恶化和全因死亡的综合结果。我们对共病哮喘进行了相互作用分析。结果:在56,523例COPD患者的登记中,5,661例收集了异丙嗪(n = 3,723)或褪黑素(n = 1,938)。3,290名异丙嗪或褪黑激素治疗的患者进行了1:1的配对,可用于初步分析。在1年内,异丙嗪治疗的患者发生主要结局的风险高于对照组,风险比(HR)为1.42 (CI 1.27-1.58, p p p = 0.19)。对整个人群进行校正后的Cox分析表明,服用异丙嗪的风险进一步增加(在服用异丙嗪≥400片/年的患者中,主要结局HR =2.15, CI 1.94-2.38)。结论:与褪黑激素相比,异丙嗪治疗的COPD患者存在严重恶化和全因死亡的复合结局风险。

Background: Treatment guidelines for asthma management are derived almost exclusively from the results of controlled clinical trials undertaken in carefully selected patient populations; meaning that their outcomes may not reflect the true performance of treatments when used in general daily medical practice. The aim of this meta-analysis was to combine the results of observational studies investigating the fluticasone propionate/formoterol (FP/FORM) fixed-dose combination in real-world asthma patients.
Methods: A systemic literature review was completed in March 2019 using the PubMed database. We identified 394 studies. Five studies, which included a total of 4756 patients treated with FP/FORM, were judged eligible and included in the meta-analysis.
Results: The estimated severe asthma exacerbation rate was 11.47% (95% CI, 5.8 to 18.72%), calculated from the random effect model. A sensitivity analysis excluding 2 studies (one was an outlier, and the exacerbation rate for the studied treatment alone could not be determined in the other) showed a 7.04% rate of severe asthma exacerbations. The estimated relative risk of the incidence of severe asthma exacerbations was 0.323 (95% CI, 0.159 to 0.658). The estimated asthma control rate was 60.6% (95% CI, 55.7% to 65.6%). The odds of achieving asthma control significantly increased by FP/FORM compared with pre-study conditions (estimated odds ratio: 2.214 [95% CI, 1.292 to 3.795]; p < 0.001).
Conclusions: The findings of this meta-analysis confirm the effectiveness of FP/FORM for the treatment of asthma patients in a real-world setting beyond the limitations of RCTs.

To the Editor: It has been 3 years since the world was confronted with a new challenge: coronavirus disease 2019 (COVID-19) [1]. COVID-19 typically manifests with respiratory symptoms, such as dry cough and dyspnea; however, it is not unusual for other organ signs and symptoms to appear [2]. A 2020 meta-analysis found that 53% of COVID19 patients suffer from taste and smell impairments [3]. Anosmia, the loss of the sense of smell, is one of them and is regarded both as a symptom and as a complication of COVID-19, which may remain even after the patient is no longer infected [3]. Sixty to seventy percent of patients recover from this disorder within 4 weeks after having COVID19, either entirely or partially [2]. Seventy-eight percent of patients recover their sense of smell entirely after 2 months, while 95% do so after 6 months [2,3]. Nonetheless, some people may endure anosmia for more than a year. These patients undergo numerous diagnostic and therapeutic procedures but do not heal completely [4]. Several therapy approaches might be pursued when anosmia persists for longer than 2 weeks [4]. Current options for treatment include intranasal corticosteroids, sodium citrate, and olfactory exercises [2]. Some patients do not respond to these treatments and have permanent olfactory loss. These patients may be candidates for other experimental therapies, such as stem cell therapy [2]. On 10 April 2020, a 23-year-old woman presented to the pulmonology clinic of Imam Khomeini Hospital in Sari, Mazandaran Province, Iran, with a complaint of a dry cough, fever, and loss of smell. On physical examination, her vital signs and organ examinations were normal. She tested positive for COVID-19 with a PCR test. The patient was ultimately diagnosed with mild COVID19. On the subsequent follow-up, her respiratory symptoms improved, but her anosmia did not. On 1 November 2022, she returned and reported that she could once again detect odors. She stated that approximately a month ago, she occasionally detected odors for a short period. Over time, the duration and intensity of the odor from these episodes began to increase. Now, she has regained her original sense of smell. Several hypotheses have been proposed as potential anosmic mechanisms. A study by Torabi et al. [5]. Based on the fact that TNFand IL-1 are high in COVID-19 patients, they suggested that inflammation of the olfactory epithelium could be a cause of short-term anosmia. This can explain why intranasal corticosteroids have the desired effects on COVID-19 anosmia. Cazzolla et al. [6] evaluated the IL-6 levels in venous blood samples of anosmic COVID-19 patients and concluded that recovery of the sense of smell correlates with a decrease in IL-6 blood levels. Other pathways associated with persistent anosmia in COVID-19 patients include olfactory cleft syndrome, olfactory epithelium or bulbar injury, microglial cell destruction, and apoptosis of olfactory neurons and stem cells [2]. Moreover, prolonged S
