Impact of Bronchiectasis on COPD Exacerbations

Apr 2018

The presence of bronchiectasis is considered an aggravating factor in COPD patients. In particular, the coexistence of bronchiectasis and COPD was associated with greater frequency and severity of exacerbations. The aim of this study is to investigate the impact of bronchiectasis in patients with COPD exacerbation. We retrospectively collected data from 212 patients admitted to the hospital with diagnosis of COPD exacerbation. In order to detect the presence of bronchiectasis, only patients that had received a chest HRCT scan examination were included in the study. We compared clinical and functional data between COPD patients with bronchiectasis and those without bronchiectasis. The prevalence of bronchiectasis was 31,6% in this study. The presence of bronchiectasis in COPD patients was associated with increased risk for isolation of PPMs in the airway (56,1% vs 28,3%, p 0,02), and in particular of Pseudomonas Aeruginosa (17,5% vs 5,6% p 0,02), and with a longer duration of hospitalization (8,22 ±3,67 vs 6,88 ± 3,43 days, p=0.004). These results could encourage efforts to optimize medical care for patients with COPD and bronchiectasis. Clinical trials with treatments for infective component are needed to investigate their impact on the reductions of exacerbations and improvements in the disease course.

Spirometric profile of people living with HIV on antiretroviral drugs in Abidjan

Jan 2024 DOI 10.14302/issn.2642-9241.jrd-23-4809

Introduction People living with HIV (PLHIV) are susceptible to developing non- communicable chronic respiratory diseases. Our objective was to study the spirometric profile of this population. Material and methods This was a descriptive and analytical cross-sectional retro-prospective study conducted from March 15 to June 15, 2022 and relating to the analysis of the medical files of asymptomatic and eligible for spirometry PLHIV, aged 18 years and above. They were received in the voluntary counselling and testing (VCT) centres of one of the two pulmonology departments in Abidjan. Results The study involved 54 subjects including 22 men (40.7%) and 32 women (59.3%) with an average age of 48.9 years. The majority of patients were non-smokers (81.4%) and the main history was pulmonary tuberculosis (35.2%). Only 29.6% had chronic respiratory symptoms and 42.6% had a normal BMI. The frequency of spirometric abnormalities was 57.4%. These spirometric abnormalities included 40.7% peripheral obstructive pattern; 9.3% restrictive pattern; 3.7% asthma and 3.7% COPD. A more than 10 years duration of HIV infection (p=0.001 OR= 0.2 (0.1 – 0.7)) and a duration of ART of at least 10 years (p=0.001 OR= 0, 2 (0.1 – 0.7)) were significantly associated with the existence of ventilatory abnormalities. Conclusion The high frequency of ventilatory anomalies in PLHIV independently of the existence of chronic respiratory signs leads us to propose spirometry in the follow-up assessment of PLHIV while paying particular attention to those on ARVs for more than 10 years.

Jun 2022 DOI 10.14302/issn.2642-9241.jrd-22-4181

Introduction Worldwide, the Chronic Obstructive Pulmonary Disease (COPD) is a major public health concern; On the basis of epidemiologic data, by 2020, COPD will be the third leading cause of death worldwide. Objective To assess the frequency of Microalbuminuria and the presence of Hypoxemia in patients with COPD. Materials and Methods Study Design Cross-sectional observational study. Place of Study Department of Medicine & Respiratory Medicine in Dhaka Medical College Hospital (DMCH). Study Period Six months after approval of the protocol Study Population Patient suffering from COPD and admitted in Department of Medicine & Respiratory medicine, DMCH, Dhaka, Bangladesh. Total 100 samples were included in this study. COPD usually presents with a history of chronic cough with sputum production or exertional breathlessness which may be associated with relevant clinical findings and a post-bronchodilator FEV1/FVC less than 0.7. In most cases it is associated with smoking Results Total 100 patients of COPD were included in the study. Mean age was 58.16±5.4 years ranging from 50 to 74 years. Out of 100 patients, majority (42%) were from age group 55 to 60 years. Among all, 82% patients were male and 18% were female, of 100 patients, majority (30%) were day laborer. Only 2% were unemployed. The percentage of housewives was 18%. Other 34% were businessman and service holders. COPD severity was assessed using GOLD guideline. Out of 100 COPD patients, 38% had severe COPD (GOLD stage III). 16 % patients were in mild (Stage I) and 32% patients were in moderate stage (Stage II). The condition was very severe for 14% patients (Stage IV). Of 100 COPD patients, 30% had microalbuminuria. Among 100 COPD patients, chance of microalbuminuria increases among COPD patients with the increase of age significantly. There is smoking history of 36 pack year for COPD patients with microalbuminuria. Of 100 patients 26% were hypoxemic. The average forced expiratory volume (FEV1%) was 37.40 with standard deviation 14.48 for patients with microalbuminuria. The PaO2 and PaCO2 is 63.06 with standard deviation 7.09 and 46.09 with standard deviation 2.43 for COPD patients with microalbuminuria respectively. All of these characteristics are significant with p-value 0.00. However, the body mass index (BMI), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were not found significant. The patients who had PaO2 less than 70 mmHg were considered hypoxemic. The patients who had microalbuminuria among them 87% were hypoxemic. Only 13% patients were free from hypoxemia who had microalbuminuria. Patients without microalbuminuria had no history of hypoxemia. There is significant relation exists between hypoxemia and the presence of microalbuminuria (p<0.5). Conclusion In this study, about one-fourth of the patients have hypoxemia and more than one fourth of the patients have microalbuminuria. Stage III was more frequent among the study population but there was no association between severity grading and presence of microalbuminuria. However, significant relation is found between co-existence of both microalbuminuria and hypoxemia in COPD patients.

Evaluation of Anti-Aging Activity of the Biofield Energy Treated Novel Test Formulation Using SIRT1 and Telomerase Activity in in Vitro Model

Sep 2019 DOI 10.14302/issn.2474-7785.jarh-19-2994

Telomerase and SIRT1 (member of the sirtuin protein family) along with the lifestyle and diet are the major determinants of aging and its associated diseases such as cancer and cardiovascular disorders. The study objective was to investigate the effect of Consciousness Energy Healing based novel test formulation in pre-adipocytes (3T3-L1) and human peripheral blood mononuclear cells (PBMCs) for anti-aging activity using SIRT1 and telomerase assay. The test formulation was divided into two parts. One portion was denoted as the untreated test item without any Biofield Energy Treatment, while the other portion was defined as the Biofield Energy Healing Treatment, which received the Biofield Energy Healing Treatment by a renowned Biofield Energy Healer, Mahendra Kumar Trivedi. The cell viability using MTT assay showed that the cell viability of 3T3-L1 and PBMCs cells was more than 70% indicating a safe and nontoxic profile. The experimental data in PBMCs cells showed that the Biofield Energy Treated Test formulation showed a significant improved telomerase activity by 39.25%, 20.86%, and 17.95% at concentrations 0.01, 5, and 100 µg/mL, respectively as compared with the untreated test formulation group. These results indicate that the Biofield Energy Healing Treatment would be the significant approach to prevent aging-related disorders such as decline cardiovascular diseases, osteoporosis, dementia, osteoarthritis, Alzheimer’s, hypertension, cancer, Parkinson's Disease, Chronic Obstructive Pulmonary Disease (COPD), Stress, Asthma, cataract, age-related macular degeneration (AMD), hearing loss and metabolic disorders.

Evaluation of Co-morbidities among Different Chronic Obstructive Pulmonary Disease Phenotypes

Aug 2018

Background: Co-morbidities are associated with increasing risk of mortality, hospitalizations and costs of treatment in Chronic Obstructive Pulmonary Disease patients. Identification of Co- morbidities related to COPD phenotypes may guide individualized therapies and achieve better prognosis. Methods: A prospective study of one hundred ten patients of confirmed COPD diagnosis were carried out and divided into five different phenotypes with related co-morbidities. History taking, clinical examination, Chest X-ray, Computed chest Tomography, laboratory investigations, arterial blood gas, Echocardiography and Electrocardiography were done for all patients. St. George’s Respiratory Questionnaire, COPD assessment test (CAT score) and BODEx (BMI, FEV1, dyspnea and exacerbations) were used for assessment of disease impact on quality of life, severity, and exacerbation respectively. Results: Emphysema group were 31% among all cases with mean age 61.8±9.1, frequent exacerbator group and Chronic bronchitis phenotype were 18% with mean age 64.4±11.3, and 48.8±9 respectively. COPD with bronchiectasis group were 19% with mean age 60.3±6 and Asthma COPD Overlap Syndrome (ACOS) were 12% with mean age 62.8±15.8. There was significant difference as regards age between different group of phenotypes P- value <0.001. There was significance difference in BODEx index and in (CAT) score among different COPD phenotypes P-value 0.020, 0.001 respectively. There was significant difference in all items of SGRQ among different COPD phenotypes P–value 0.001. Diabetes was commonly presented in 50 % ACOS cases, Ischemic heart disease was present more in Emphysema 22.9%, Osteoporosis was more in COPD with bronchiectasis 28.6%, Cor-pulmonale was more present in frequent excerbator 65%, and Anemia more common in COPD with bronchiectasis 23.8%. Depression was more common in frequent excerbator phenotype (45.0 %). Gastro-esophageal reflux was the most common co-morbidities (58 %) then cor-pulmonale 41.8%, systemic hypertension 40 % and pulmonary hypertension 28%. Conclusion: The presence of significant co-morbidities is important modifying risk factors for severity in COPD. They contribute to the overall severity in individual patients, have a major impact on quality of life, and major causes of hospitalization. Co-morbidities can be associated with any clinical phenotype.

Results of Bronchoscopic Lung Volume Reduction with One-way Valve in Patients with Severe Emphysema in Vietnam

Mar 2018 DOI 10.14302/issn.2642-9241.jrd-18-1958

Background Bronchoscopic lung volume reduction (BLVR) has been applied in COPD patients with heterogeneous emphysema. In this first clinical trial in Vietnam, we evaluated the safety and initial results of BLVR by one-way valve in COPD patients with severe emphysema. Methods We performed a prospective, nonrandomized, single center longitudinal study in 30 stable COPD patients with heterogeneous severe emphysema on CT-scanner, the average age of 65.17 years old, FEV1≤35 %pred., TLC ≥ 100 %pred., RV ≥ 150 %pred. and 6MWT < 450 meters. The Zephyr one-way bronchial valves (PulmonX, Redwood City, CA, USA) with the size of 5.5 mm and 4mm were placed in lobar or segmental bronchi via flexible bronchoscopy. 28 patients were placed only one valve, 1 patient with two and 1 patient with three valves. 23 valves with the size 5.5 mm diameters and 10 valves with the size 4.0mm used. All patients received optimal medical treatment at the time of procedure and during the study period. Outcomes will be assessed at 3 months after treatment include the changes of clinic, and lung function, the occurrence of complications. Results After 3 months, mean CAT scores decreased significantly compared with before procedure (17.73 ± 3.53 vs 20.10 ± 3.58) (p<0.05), with the median change of 2.73 points and the improvement more than 2 points in 76.67% of patients. 6 MWT increased at 3 months with mean 32.13 meters, 93.33% of the patients increased 6MWT, 46.67% of the patients increased 6MWT more than 26 meters. MRC decreased with the median change of 0.5 score. VC decreased by a mean 0.2 (L) (0.42 - 0.02), FEV1 increased by a mean 0.05 (L) (0.04 - 0.05) but not statistically significant (p>0.05); FVC increased by a mean 0.14 (L) (0.01 - 0.28), RV decreased by a mean 0.62 (L) (1.05 - 0.2), TLC decreased by a mean 0.52 (L) (0.77- 2.4) with statistically significant (P<0.05). The early complications were 13.33%, the later complications were 23.34% of the patients. Conclusions The unilateral bronchoscopic lung volume reduction with one-way valve (mainly one valve) in treatment of heterogeneous severe emphysema in stable COPD patients in Viet Nam have shown that this procedure is safe with encouraging initial results.

Development of a Chronic Obstructive Pulmonary Disease Severity Classification System Using A Japanese Health Insurance Claims Database

Sep 2017 DOI 10.14302/issn.2474-7785.jarh-17-1727

Background: Healthcare services provided to patients should vary depending on disease severity. However, disease severity bias, a type of selection bias, is a commonly encountered problem in administrative database studies. Herein, we selected chronic obstructive pulmonary disease (COPD), which commonly affects elderly Japanese citizens, for the development and validation of a severity classification system based on a health insurance claims database. Methods: Patients who received COPD-related diagnostic codes in 2011 were selected from a commercially based health insurance claims database. COPD patients were randomly divided into two groups to develop and validate severity scores. A principal component analysis was used to estimate factor loadings used to weight calculations of COPD severity scores. Score validity was evaluated using a linear trend test to predict COPD treatment costs and acute exacerbation events. Results: Using records from 880 patients, ten variables were created: acute exacerbation events, emphysema diagnoses, laboratory test and oxygen therapy procedures, prescribed anticholinergic, inhaled corticosteroid (ICS), short acting beta-agonist, and long acting bronchodilator (LABA) agents, asthma diagnosis and patient birth years. Factor loadings from LABA and ICS prescriptions had the strongest impacts on estimated severity scores (0.50 and 0.49, respectively). Among 300 validation group patients, scores were found to associate with increasing trends of median costs and exacerbation risks (p for trend < 0.05). Conclusions: Estimatedseverity scores would help to predict COPD-related medical costs and exacerbation events. For further clinical implementation, this classification system should be re-evaluated using clinical lung functions information indicative COPD severity and treatment choices.
