Cytokines are important in many pathobiological processes of chronic obstructive pulmonary disease (COPD). This study aimed to determine the relationship between serum levels of interleukin-33 (IL- 33) and the severity of COPD disease.

In this cross-sectional research, the study population consisted of all COPD patients referring to the pulmonary clinic of Imam-Ali Hospital of Zahedan city. Sixty patients were selected using the available sampling method. Serum IL-33 levels were measured by the quantitative ELISA method.

Of 60 patients, 23 (38.3%) and 37 (61.7%) subjects were male and female, respectively. Analysis shows a significant difference between serum IL-33 of the two groups with regard to the severity of COPD disease. There was a statistically significant negative relationship between the serum level of IL-33 and the severity (decrease of forced expiratory volume in one second (FEV1)) of COPD disease.

Our results indicate a systemic release of IL-33 correlated with the severity of COPD.

The current study tried to assess the effects of CKD on the severity and outcome of COPD in a population of patients who referred to our tertiary center in Tehran through a 3-year time section.
Through a retrospective cross-sectional design, the current study tried to assess the effects of chronic kidney disease (CKD) on the health situation and some spirometric and para-clinical parameters as well as their outcomes in patients who had been hospitalized for COPD. The participants had already COPD and we separate them into two groups with or without CKD.
Regarding the outcome of hospitalizations, 94% of the COPD and 77.9% of the COPD+CKD group were discharged in good health condition while 6% and 22.1% deceased, respectively. This shows significantly higher death rate in the latter group and the findings obtained the odds ratio of 4.5 for CKD to raise this rate.
The current study could suggest an absolute relationship between CKD and COPD in terms of respiratory and blood parameters as well as the mutual effects of the diseases on the outcome of each.

Inhaled corticosteroids (ICSs) have been widely used in the maintenance therapy of chronic obstructive pulmonary disease (COPD). Eosinophilic airway inflammation is a recognized inflammatory endotype in COPD. Nevertheless, the benefits and risks of ICS treatment remain controversial.

Therefore, in this study, we determine the frequency of eosinophilia in COPD patients and compare the effects of ICSs in patients with and without eosinophilia referring to the lung clinics of Zahedan University of Medical Sciences.

In this study, 58 COPD patients were examined. Peripheral blood smears (PBS) were collected from all patients, and they were randomly divided into 2 groups. First, a 6-minute walking test (6MWT) was performed on all patients. Thereafter, two groups of patients received standard treatment with the Symbicort spray for 3 months. They were followed for this period, and the 6MWT was performed again at the end of the 3 months.

The mean results of the 6MWT test before and after intervention in the eosinophilia-positive group were 164.02 meters and 192.11 meters, respectively. Therefore, there was a significant difference in patient activity levels before and after ICSs (P = 0.017). In the eosinophilia-negative group, there was a significant difference in patient activity levels based on the 6MWT test before and after taking ICSs (P < 0.001). However, there was no difference in activity levels between the two groups before and after the intervention (P = 0.68 and P = 0.36).

Our finding showed that treatment with inhaled β2-agonists plus corticosteroids did not affect the response to this treatment in subjects' groups with and without eosinophilia compared to the pre-treatment conditions.

Chronic Obstructive Pulmonary Disease (COPD) exacerbation is characterized by both airway and systemic inflammation. The present study aimed to investigate the relationship between serum levels of some inflammatory biomarkers and the phenotypes of COPD exacerbation.
This study includes known COPD patients, presenting to a hospital with acute exacerbation of COPD. Serum levels of CRP, ESR, CBC, TNF-α, IL-8, and IL-6 were measured at the time of admission. According to the previously done HRCT, the patients were divided into two groups including emphysema and chronic bronchitis. Levels of serum biomarkers were compared in the two groups. The relationships between biomarkers and duration of hospitalization were assessed too.
  Comparison of quantitative CRP levels, WBC, and platelet counts did not show a statistically significant difference between emphysema and chronic bronchitis but it was significantly higher than control subjects. Although not statistically significant, ESR level was higher in emphysema. TNF-alpha was 6.0±1.5 ng / ml and 1.5 ng / ml in the emphysema and chronic bronchitis groups, respectively. TNF-α had no significant difference compared to the groups. Although higher than the control group, IL-6 and IL-8 did not show significant differences between emphysema and chronic bronchitis. The two groups did not statistically differ in terms of hospital stay but patients with higher serum TNF-α tended to have longer hospitalization and ICU admission. The present study showed predictably higher inflammatory biomarkers in COPD exacerbation but no significant difference between the two phenotypes of COPD and these two entities could not be discriminated based on inflammatory bio-factors.

Chronic obstructive pulmonary disease (COPD) is one of the most common pulmonary diseases. The current therapeutic outcomes are not satisfactory and may cause adverse events such as cardiovascular complications. In this study, we aimed to discuss some effective medicinal herbs for the management of COPD.

In this review, we looked for effective medicinal herbs for productive cough with thick and sticky mucus in Persian medicine sources such as Qanoon fi al-Teb, Exir Azam, and Zakhire Kharazmshahi. Then, to find relevant evidence about them, the data sources (PubMed and Google Scholar) were searched in the English language without time restriction from inception up to March 2022.

We found that Zataria multiflora, Thymus vulgaris L, Glycyrrhiza glabra L., Crocus sativus L., Nepeta bracteata Benth., and Hyssopus officinalis have beneficial effects on COPD due to their properties including anti-inflammatory and antioxidant activity. In addition, considering asthma COPD overlap (ACO), medicinal herbs including Cordia myxa, Adiantum capillus-veneris, Cinnamomum verum, Viola odorata, Borago officinalis, Linum usitatissimum and Vitis viniferia L. were found to have useful effects on asthma.

Considering the mentioned beneficial mechanisms of action of these medicinal herbs, they could be used as a complementary therapy in COPD and asthma. However, more experimental and clinical research should be done to confirm their clinical effects.

Chronic obstructive pulmonary disease (COPD) has become a global public health problem due to its high mortality. So there is an urgent need to find an effective treatment

The targeting relationship among circABCB10, miR-130a and PTEN was predicted by  the targetscan database. The lung condition was detected by CT(Computed Tomograph). The expression levels of circABCB10, miR-130a and PTEN in lung tissues were determined by qRT-PCR. The COPD model was established by stimulating normal and silenced 16HBE cells in circABCB10 genes with cigarette smoke extract (CSE) at different concentrations. qRT-PCR was conducted for the expression levels of circABCB10, miR-130a and PTEN, WB for the expression levels of apoptotic proteins,ELISA for the content of inflammatory factors,and CCK8 for the effect of CSE on the proliferation of cells.

CircABCB10 expression increased in lung tissues from patients with COPD and in 16HBE cells treated with CSE. The stimulation on cells with CSE increased the expression of inflammatory factors, while knocking down circABCB10 could reverse this response. The inflammatory response to the knockdown of circABCB10 was reversed by miR-130a inhibitor, which increased the expression of c-caspase 3. The targetscan database predicted the target factor downstream miR-130a was PTEN. Transfecting OE-PTEN reversed the inflammation of knocking down circABCB10, and increased the apoptosis and inflammation.

CircABCB10 can cause the inflammatory response by targeting miR-130a/PTEN axis, which is a mechanism that may lead to the occurrence and development of COPD.

Asthma and chronic obstructive pulmonary disease (COPD) are the most common chronic diseases with a high global burden of disease. Today, the use of complementary and alternative medicine (CAM) has become more popular. In general, in developing countries, easy access and low cost of traditional medicine, and in developed countries, more access to health information, the prevalence of old age and the increase in chronic diseases are the reasons for this increasing use of traditional medicine. This study aimed to determine the rate and pattern of CAM used and their relationships with demographic characteristics among asthmatic and COPD patients. This research was a cross-sectional study performed on asthma and COPD patients (n=357) referring to the Pulmonary Diseases affiliated with Ardabil University of Medical Sciences, Ardabil, Iran from 2019 to 2020. Data were collected by using semi-structured questionnaires including open and closed questions and face-to-face interviews. Three hundred and thirty-nine patients (95%) used at least one type of CAM in the last year of study. About half of the patients (49.9%) used more than two types of CAM during the last 12 months. Three hundred and four patients (85.2%) used medicinal plants. Few patients reported with the use of CAM to their physician or health care providers (16.1%, 12.5%, and 16.7% of the users of medicinal plants, bloodletting, and dry cupping respectively). Relatives and friends (77.9%) were with the most common sources of recommendation of CAM to the patients. The present study showed the high prevalence of using different types of CAM, especially herbal medicines in Iranian asthmatic and COPD patients. The main incentive for using CAM was for friends and family members, not health care providers. The use of CAM is associated with age patients age, family size, habitat, education, and occupation.

Context: 

A wide range of complications, including chronic respiratory diseases, asthma attacks, cardiovascular diseases (CDs), various cancers (blood, lung, and brain), and even death, can result from air pollution. It is essential to assess the health effects on humans caused by environmental air pollutants and non-communicable diseases (NCDs), including coronavirus disease 2019 (COVID-19). The purpose of this review study was to investigate the synergistic effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and air pollutants on the risk factors for chronic obstructive pulmonary disease (COPD), CDs, and respiratory diseases (RDs).

Evidence Acquisition: 

An extensive literature review was conducted. A total of 1 005 articles were retrieved from sources, including Google Scholar, Springer, PubMed, Web of Science, and Springer databases. In the final stage of the literature review, a significant association between mortality related to COVID-19 and air pollution emissions was identified, contributing to the risk factors associated with CDs and RDs.

The result showed that air pollution can have synergistic effects on the transmission of SARS-CoV-2 viruses and has an increasing effect on the incidence of RDs [such as SARS and Middle East respiratory syndrome (MERS)] and CDs. According to the findings, exposure to toxic air pollutants, whether chronic or acute, can have severe effects, including a decrease in airway ciliary function, damage to the mucous membrane, reduced air sac elasticity, decreased lung capacity, and an increased risk of CDs.

COVID-19 and air pollutants pose a serious threat to human and animal health. Epidemiological studies have shown that in addition to environmental conditions, individual sensitivity plays a key role in the development of conditions such as COPD, CDs, RDs, cancer, and mortality.

 Limitations of activities of daily living (ADLs) are well-known in chronic obstructive pulmonary disease (COPD) patients. However, a lack of consensus regarding the concept of ADL in COPD patients causes problems in their measurement. This study was conducted to clarify and conceptualize the concept of ADLs in COPD.

 The hybrid model of concept analysis consisting of a literature review phase, a fieldwork phase, and an analytical phase was applied. In the first phase, an extensive literature review was performed by searching the accredited databases for relevant articles published within 2000-2022. In the second phase, 18 in-depth interviews with COPD patients were carried out in Tehran, Iran. Field observational notes were transcribed verbatim, and qualitative content analysis was performed. In the analytical phase, attributes of ADLs were derived from the previous two phases.

 Based on the attributes derived from the final analytical phase, ADLs in COPD patients are complex and multifactorial and are affected by dyspnea and factors influencing it. The pattern of daily activities, communication, and self-care in COPD patients changes toward living normally and independently.

 The concept analysis of ADLs in COPD patients revealed some key attributes. The results might be useful for designing nursing models, developing theories and measurement tools, and increasing the capacity to perform ADLs in COPD patients.

Gamma-glutamyl transferase (GGT) is a liver enzyme that is involved in inflammation and oxidative stress. It has been hypothesized that elevated GGT may occur secondary to oxidative stress in acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and can be used as an indicator of inflammation in these patients. The present study aimed to determine the relationship between serum GGT and arterial blood gas (ABGs) on the one hand and COPD severity in AECOPD patients on the other hand. Patients with AECOPD were evaluated for disease severity based on the global initiative for chronic obstructive lung disease (GOLD), Modified British Medical Research Council (mMRC), COPD Assessment Test (CAT), and spirometry assessment upon admission at the hospital. Moreover, the GGT level in patients was analyzed based on the severity of the disease. The data were analyzed using SPSS software (version 25.0) by proper statistical tests. The significance level was P˂0.05. The mean±SD of the CAT score in the patients was obtained at 19.6± 4.6. According to the mMRC scale, most patients were grade 2 (n=29, 52.7%) and grade 1 (n=17, 30.9%), respectively. In addition, according to GOLD criteria, most patients (n=34, 61.8%) had moderate and severe (n=16, 29.1%) disease, respectively. The median (IQR) GGT levels in patients with mMRC 0-1 were 28.7 (12.98) IU/L, and those with mMRC 2-4 were 21 (33) IU/L (P=0.770). Additionally, the median (IQR) of GGT levels in patients in GOLD A-B were obtained at 26(18) IU/L, and in patients in GOLD C-D were reported as 18 (23.80) IU/L (P=0.222). The results showed a significant positive relationship between GGT level and AECOPD severity (r=+0.277, P=0.04). Moreover, a significant negative relationship was observed between GGT level and forced vital capacity (FVC) (r=-0.268, P=0.04). According to the Pearson correlation test, There was no significant correlation between GGT level with arterial HCO3 (P=0.123), PCO2 (P=0.511), PO2 (P=0.888), FEV1 (P=0.356), and FEV1/FVC (P=0.975). In conclusion, while a significant positive relationship was found between GGT levels and AECOPD severity, the study suggests that serum GGT levels may not have clinical efficacy in differentiating between patients with varying intensities of AECOPD periods. Further research with larger sample sizes and consideration of additional factors is warranted to confirm these findings.

COPD and metabolic syndrome are highly prevalent and contribute significantly to morbidity and mortality worldwide. Limited evidence suggests a higher prevalence of metabolic syndrome in COPD patients, indicating a potential link between metabolic syndrome and impaired lung function. We aimed to study the correlation between COPD severity and metabolic syndrome components, and between CRP and COPD severity.

This cross-sectional observational study involved 100 COPD outpatients. Metabolic syndrome parameters were assessed using NCEP criteria. Patients were categorized per GOLD classification using MMRC grading and spirometry. We compared blood pressure, blood glucose, cholesterol, triglycerides, and waist circumference across GOLD stages, and clinical, metabolic, and spirometry parameters between those with and without metabolic syndrome. Analysis was performed using GraphPad Prism 9 and SPSS 26.0.

48% of COPD patients had metabolic syndrome. SBP, blood glucose and triglycerides were significantly higher in severe COPD compared to stages I and II. Among metabolic parameters, blood glucose and SBP were significant negative predictors of FEV1/FVC adjusted for age, smoking and BMI. CRP level, diabetes, hypertension, and abdominal adiposity were associated with airflow limitation severity. FEV1/FVC was significantly lower in extreme BMI groups. Those with metabolic syndrome had higher MMRC grade, exacerbation rate, and CRP, but lower FEV1/FVC and smoking history than those without.

This study emphasizes assessing and managing metabolic syndrome in COPD patients, and suggests links between inflammation, metabolic syndrome, and impaired lung function.

Context:

 Fatigue and the reduced quality of life are among the most common problems of patients with chronic obstructive pulmonary disease (COPD), affecting all aspects of life in these patients.

 This study aimed to evaluate the effects of self‑care program based on the Orem self‑care model on fatigue and quality of life in patients with COPD.

Setting and Design: 

This was a randomized controlled trial conducted on 66 patients with COPD who were admitted to hospitals of Shahrekord University of Medical Sciences, Iran.

 The patients were randomized either to the intervention group or control group using random numbers by random allocation software. The intervention group received self‑care program based on the Orem’s self‑care theory, including four educational sessions as well as a 2‑month follow‑up. The control group received only usual care. The needed data were collected using the Fatigue Severity Scale and 12‑item Short‑Form Health Survey questionnaire once before and once after the interventions and then analyzed using descriptive and analytic statistics.

Statistical Analysis Used: 

These data were analyzed by SPSS software using descriptive and analytic statistics.

 In the intervention group, the mean score of fatigue reduced and the mean score of quality of life significantly increased after performing the interventions (P < 0.05). Moreover, the mean scores of fatigue and quality of life were significantly different between the groups (P < 0.05). The mean changes in terms of fatigue and quality of life scores were significantly greater in the intervention group compared to the control group (P < 0.05).

 Orem’s self‑care theory is an effective nursing theoretical framework used to reduce fatigue and improve quality of life, thus it can be used for other chronic diseases and conditions as well.
