The evaluation of disease awareness, caregiver burden, and workday loss in caregivers of COPD patients.

BACKGROUND: Our aim is to determine the caregiver burden of chronic obstructive lung disease (COPD) patient's caregivers, and to determine whether there is a workday loss. METHODS: 252 COPD patients and their caregivers were included. Disease information of the patients were recorded and a questionnaire was applied. Socio-demographic characteristics of the caregivers were recorded and a questionnaire consisting of 24 questions including COPD disease, treatment and loss of working days, and the Zarit Scale were used. RESULTS: 128(50.8%) of the patients according to GOLD were group-D, 97(38.5%) of the patient's relatives were working, 62(24.7%) were not able to go to work for 1-14 days, and 125(57.1%) spent outside the home from 1-14 nights, because those accompanied to patients. In univariate analysis were detected modified medical research council (mMRC) (p < 0.001), CAT (p < 0.001), the number of comorbidities of patients (p = 0.027), forced expiratory volume in 1 FEV1cc (p = 0.009), FEV1% (p < 0.001), the presence of long term oxygen therapy (LTOT), and the number of comorbidities of the patient's relatives (p = 0.06) increased the care load. In multiple linear regression analysis, age (p = 0.03), COPD assessment test (CAT) score (p = 0.001), FEV1% (<0.068) and the number of comorbidities of patients (p = 0.01) and the number of comorbidities of caregivers (p = 0.003) increased the caregiving burden. DISCUSSION: In COPD increases caregiving burden. This burden is greater in symptomatic patients and when comorbidities are present. Psychosocial and legal regulations should be investigated and solutions should be produced for the caregivers of COPD patients.

Short-acting ß2-agonist prescription patterns in patients with asthma in Turkey: results from SABINA III.

BACKGROUND: Over-reliance on short-acting ß2-agonists (SABAs) is associated with poor asthma outcomes. However, the extent of SABA use in Turkey is unclear owing to a lack of comprehensive healthcare databases. Here, we describe the demographics, disease characteristics and treatment patterns from the Turkish cohort of the SABA use IN Asthma (SABINA) III study. METHODS: This observational, cross-sectional study included patients aged ≥ 12 years with asthma from 24 centres across Turkey. Data on sociodemographics, disease characteristics and asthma treatments were collected using electronic case report forms. Patients were classified by investigator-defined asthma severity (guided by the 2017 Global Initiative for Asthma [GINA]) and practice type (primary/specialist care). The primary objective was to describe SABA prescription patterns in the 12 months prior to the study visit. RESULTS: Overall, 579 patients were included (mean age [standard deviation; SD]: 47.4 [16.1] years; 74.3% female), all of whom were treated by specialists. Most patients had moderate-to-severe asthma (82.7%, GINA steps 3-5), were overweight or obese (70.5%), had high school or university/post-graduate education (51.8%) and reported fully reimbursed healthcare (97.1%). The mean (SD) asthma duration was 12.0 (9.9) years. Asthma was partly controlled/uncontrolled in 56.3% of patients, and 46.5% experienced ≥ 1 severe exacerbation in the preceding 12 months. Overall, 23.9% of patients were prescribed ≥ 3 SABA canisters in the previous 12 months (considered over-prescription); 42.9% received no SABA prescriptions. As few patients had mild asthma, only 5.7% were prescribed SABA monotherapy. Therefore, most patients (61.5%) were prescribed SABA in addition to maintenance therapy, with 42.8% receiving ≥ 3 SABA canisters in the previous 12 months. Inhaled corticosteroids (ICS), ICS + a long-acting ß-agonist fixed-dose combination and oral corticosteroids were prescribed to 14.5%, 88.3% and 28.5% of all patients, respectively. Additionally, 10.2% of patients purchased SABA over the counter, of whom 27.1% purchased ≥ 3 canisters in the preceding 12 months. CONCLUSIONS: Despite all patients being treated by specialists and most receiving fully reimbursed healthcare, nearly a quarter of patients received prescriptions for ≥ 3 SABA canisters in the previous 12 months. This highlights a public health concern and emphasizes the need to align clinical practices with the latest evidence-based recommendations.

The View of the Turkish Thoracic Society on the Report of the GOLD 2017 Global Strategy for the Diagnosis, Management, and Prevention of COPD.

Since the Global Initiative for Obstructive Lung Disease (GOLD) published its first guidelines on chronic obstructive pulmonary disease (COPD) in 2001, much has changed till 2017. Previous versions of GOLD guidelines mentioned the forced expiratory volume in one second (FEV1)-based approach for staging and treatment modalities. Since 2011, a composite multi-dimensional approach has been introduced to cover various aspects of the disease. Unfortunately, this approach was not found to be correlated with mortality as well as the FEV1-based approach, despite the fact that it was better for estimating exacerbation rates. Although this assessment tool has been considered as a big step in personalized medicine, the system was rather complex to use in daily practice. In 2017, GOLD introduced a major revision in many aspects of the disease. This mainly includes a revised assessment tool and treatment algorithm. This new ABCD algorithm has excluded spirometry for guiding pharmacological therapy. Treatment recommendations are mainly based on symptoms and exacerbation rates. Escalation and de-escalation strategies have been proposed for the first time. The spirometric measurement has only been retained to confirm the diagnosis and lead to nonpharmacological therapies. In this report, the Turkish Thoracic Society COPD assembly aimed to summarize and give an insight to the Turkish interpretation of GOLD 2017.

Updates in Chronic Obstructive Pulmonary Disease for the Year 2014.

Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality in the world. Research conducted over the past decade has contributed much to our current knowledge of the pathogenesis and treatment of COPD. Additionally, an evolving literature has recently accumulated information about the management of COPD and also about exacerbations. This article reviews a concise summary on the updates in COPD including 1) new pathogenic mechanisms and therapeutic targets, 2) management of patients in Group B, C and D according to GOLD 2014 report; 3) prevention and management of exacerbation; 4) monitoring of natural history; and 5) essential but usually forgotten parts of the management.

Assessment of long-term omalizumab treatment in patients with severe allergic asthma long-term omalizumab treatment in severe asthma.

OBJECTIVE: Several clinical studies have demonstrated the effectiveness of omalizumab in patients with severe allergic asthma but the treatment period has always been relatively short (4-12 months). In the literature, there are a few data about the long-term omalizumab therapy. We aimed to assess the long-term clinical and functional effectiveness of omalizumab treatment in severe allergic asthmatic patients, METHODS: Medical records describing the patients' status before the start of treatment, and also having been registered at the end of 4th, 12th, and 36th months from the commencement of treatment, and at the last visit where the patient was evaluated were used for omalizumab effectiveness assessments. Twenty-six patients (female/male: 21/5) with severe allergic asthma, uncontrolled despite GINA 2006 Step 4 therapy, were included in the study. Effectiveness outcomes included spirometry measurements, level of asthma control measured by asthma control test (ACT), systemic glucocorticosteroid (sGCS) use, emergency room (ER) visits, and hospitalizations for severe exacerbations. In addition, the quality of life was assessed using the quality of life questionnaire AQLQ(S) before, 4, and 36 months after treatment, RESULTS: The mean age was 47.6 ± 13.9 and duration of allergic asthma was 22.7 ± 10.1 years. Serum total IgE levels were 322.0 ± 178.1 IU/mL. Mean duration of omalizumab treatment was 40.81 ± 8.2 months. FEV1 improved significantly at all control points versus baseline (p < .05). The level of asthma control as evaluated by ACT improved significantly after treatment (p < .05). We determined significantly reduced numbers of exacerbation, emergency visits, hospitalizations, sGCS, and SABA use by the end of 36 months (p < .05). The proportion of patients with improvements larger than 1.5 points in AQLQ(S) total score was 80.7% at the 4th month and 96.1% at the 36th month of treatment, CONCLUSIONS: This study showed that long-term therapy with omalizumab for up to 3 years was well tolerated with significant improvement both in symptoms and lung functions. Accordingly, long-term omalizumab treatment may be recommended for responders.

An integrated index combined by dynamic hyperinflation and exercise capacity in the prediction of morbidity and mortality in COPD.

BACKGROUND: Dynamic hyperinflation (DH) and exercise limitation develop in patients with COPD; however, there is lack of knowledge about their long-term clinical consequences. We aimed to assess the impact of DH and exercise capacity in predicting mortality and also morbidity, as evaluated by emergency visits and hospital admissions in COPD patients during a 4-year period. METHODS: We recruited 73 stable COPD patients. The relationships of different respiratory parameters (FEV(1)%, body mass index, 6 min walk test distance [6MWD], static hyperinflation as measured by the ratio of inspiratory capacity to total lung capacity (IC/TLC) at rest, DH as measured by the change between the post- and pre-exercise values of IC/TLC [ΔIC/TLC], P(aO(2)), and P(aCO(2))) with emergency visits and hospital admissions because of exacerbations and also with respiratory and all-cause mortality were assessed. RESULTS: The median follow-up period was 47 months (IQR 45-48 months, n = 73). During the follow-up there were 8 (11%) deaths. The ΔIC/TLC value was 3.9 ± 4.6%. The Kaplan-Meier survival curve showed that the cumulative survival rate was significantly lower in the patients with ΔIC/TLC > 4 and with 6MWD ≤ 439.56 m, using these values as thresholds. (The rates for sensitivity were 100% and 87.5%, and for specificity were 56.92% and 87.69%, respectively). The Cox proportional hazards model showed that DH (hazard ratio = 1.4, 95% CI = 1.09-1.84, P = .009) and 6MWD (hazard ratio = 0.98, 95% CI = 0.97-0.99, P = .006) were independent predictors of all-cause and respiratory mortality. 6MWD, FEV(1)%, IC/TLC, and ΔIC/TLC were found to be significantly related to emergency visits (r = -0.28, r = -0.41, r = -0.24, and r = 0.38, respectively) and hospital admissions (r = -0.41, r = -0.45, r = -0.36, and r = 0.28, respectively). CONCLUSIONS: DH and exercise capacity are reliable and independent predictors for mortality and morbidity in COPD patients. We propose that DH and exercise capacity be considered in the assessment of long-term clinical consequences of COPD patients.
