Association of serum magnesium levels with frequency of acute exacerbations in chronic obstructive pulmonary disease: A prospective study

PubMed: 25485151Background. The course of chronic obstructive pulmonary disease (COPD) is accompanied by acute exacerbations. The purpose of this study is to determine the association of serum magnesium level with acute exacerbations in COPD (COPD-AE). Materials and Methods. Eighty-nine patients hospitalized with COPD-AE were included. Hemogram, biochemical tests, and arterial blood gases were analyzed. Pulmonary function tests were performed in the stable period after discharge. Patients were followed up at 3 monthly periods for one year. Results. Mean age of the patients was 70.4 ± 7.8 (range 47-90) years. Mean number of COPD-AE during follow-up was 4.0 ± 3.6 (range 0-15). On Spearman correlation analysis there were significant negative correlations between number of COPD-AE and predicted FEV1% (P = 0.001), total protein (P = 0.024), globulin (P = 0.001), creatinine (P = 0.001), and uric acid levels (P = 0.036). There were also significant positive correlations between number of COPD-AE and serum magnesium level (P < 0.001) and platelet count (P = 0.043). According to linear regression analysis predicted FEV1% (P = 0.011), serum magnesium (P < 0.001), and globulin (P = 0.006) levels were independent predictors of number of COPD-AE. Conclusions. In this small prospective observational study we found that serum magnesium level during exacerbation period was the most significant predictor of frequency of COPD-AE. © 2014 Aziz Gumus et al

Thyroid gland disease as a comorbid condition in COPD

Introduction. Chronic obstructive pulmonary disease (COPD) is one of the most common causes of morbidity and mortality worldwide. The disease is characterized by progressive airway inflammation, which not only affects the airways but also has systemic effects that are associated with comorbidities. Although comorbid conditions such as hypertension and coronary artery disease are very well-known in COPD patients, diseases of the thyroid gland have not been sufficiently studied. Therefore, thyroid diseases are not considered among the comorbid conditions of COPD. The purpose of this study was to determine the thyroid gland disease (TGD) prevalence in COPD and associated factors. Materials and Method. The study included 309 (297 (96%) male) patients. The patients were subjected to spirometry and thyroid function tests (TFT) in the stable period. The thyroid gland disease they were diagnosed with was recorded after face-to-face meetings and examining their files. Results. The mean age of the patients who were included in the study was 65.9 +/- 9.8 (40-90). Thyroid disease was determined in 68 (22%) individuals. There were hypothyroidism in 7 (2%), euthyroidism in 45 (15%), and hyperthyroidism in 16 (%5) patients. No relationship was found between the severity of airflow limitation and the prevalence of TGD. Conclusion. Thyroid abnormalities are commonly observed in COPD. The most frequently encountered TGDs are euthyroid multinodular goiter, euthyroid sick syndrome (ESS), and toxic multinodular goiter

Common variable immunodeficiency at adult age

Common Variable Immunodeficiency (CVID) is a heterogeneous group of diseases progressing with recurrent infections. This disease should be considered in cases experiencing recurrent lung infection, otitis media, rhinosinusitis, and urinary tract infection. Since it is generally seen in the childhood age group, the diagnosis in adults may be delayed. A Common Variable Immunodeficiency case, which was followed up in our clinic and characterized by recurrent upper respiratory tract infection and pneumonia, was presented to raise awareness on this issue. CVID should be kept in mind in patients who are admitted to outpatient clinics with recurrent infections, who do not respond despite appropriate treatments, and who develop complications

Is it worth using thrombolytic therapy in elderly patients with pulmonary embolism

Objective: Antithrombotic treatment is avoided in geriatric population owing to its side effects. Thus, we aimed to examine complication rates related to thrombolytic treatment in geriatric patients with pulmonary thromboembolism (PTE). Materials and Methods: The study included patients aged >65 years who received thrombolytic treatment for a diagnosis of PTE. Patient files were screened retrospectively to extract data on etiology, clinical risk scores, laboratory values, thrombolytic treatment-related complications, and early mortality development. Results: The study included 68 patients (female: 70.6%; mean age: 77.8 years). The Simplified Pulmonary Embolism Severity Index score was high in all patients. Early mortality risk classification at admission was high, medium-high, and medium-low risk in 64.7%, 23.5%, and 11.8% patients, respectively. In-hospital mortality was 30.9%. The causes of death were secondary to PTE in 85.7% patients, respiratory failure in 9.6%, and sepsis in 4.7%. Complication-related mortality was not observed. The only independent risk factor for mortality was change in consciousness. Conclusion: Mortality and complication rates in geriatric patients receiving thrombolytic treatment are not as high as expected

A novel biomarker in the diagnosis of parapneumonic effusion: neutrophil gelatinase-associated lipocalin

Background: The protein neutrophil gelatinase-associated lipocalin (NGAL) is a mediator synthesized and released by neutrophils. Its physiological function is as yet unclear. Levels in blood increase in several inflammatory diseases. High serum values indicate poor prognosis for several diseases. Pleural effusion may appear as the result of various pathologies. The most common cause is heart failure (HF). Other common causes include parapneumonic (PPE) and malignant (MPE) pleural effusions, and pulmonary embolism. Tubercular effusion (TE) is commonly encountered in Turkey and similar developing countries. The purpose of this study was to investigate the effectiveness of NGAL, a current inflammation marker, in discriminating between different etiological diseases that cause pleural effusion. Methods: The study was performed at the Recep Tayyip Erdoğan University Faculty of Medicine Chest Diseases Clinic. One hundred patients were included in the study, 25 with parapneumonic effusion, 25 with heart failure-related effusion, 25 with tubercular effusion and 25 with cancer-related effusion. NGAL was measured in patients' serum and pleural fluids. Results: Serum NGAL levels in PPE (171 ± 56 ng/ml) were significantly higher (p < 0.001) than those in HF (86 ± 31 ng/ml), CA (103 ±42 ng/ml) and TE (63 ± 19 ng/ml). Pleural NGAL levels were also significantly higher in PPE compared to HF, MPE and TE (p < 0.001). Serum NGAL levels exhibited a positive correlation with white blood cel (WBC), neutrophil, C-reactive protein (CRP), sedimentation, serum LDH, creatinine, pleural leukocyte and pleura neutrophil numbers. The most significant correlation was between NGAL level and WBC (p < 0.001, r= 0.579). Both serum and pleural NGAL levels are highly effective in differentiating patients with PPE from those without PPE (AUC: 0.910 and 0.790, respectively). Conclusions: NGAL can be used in the diagnosis of diseases with an acute inflammatory course. Serum and pleural NGAL levels can differentiate PPE from other diseases causing pleural fluid with high sensitivity and specificity. © 2014 Gümüs et al

The effect of a single hemodialysis session on pulmonary functions in patients with end-stage renal disease

Objective: Changes in pulmonary functions have not been thoroughly investigated in patients undergoing hemodialysis (HD). The aim of this study was to determine the effect of a single HD session on pulmonary functions, measured by spirometry, in patients with end-stage renal disease (ESRD) undergoing chronic hemodialysis (CHD) treatment. Methods: Thirty patients with ESRD who were on CHD treatment for at least 12 months between January 2018 and January 2020 were enrolled. The pre-dialysis and post-dialysis spirometric measurements were recorded by a portable spirometry device. Results: The mean age and HD vintage of 30 patients (70% male, 20% diabetic, mean BMI: 26.0 +/- 4.7 (kg/m(2))) were 55.6 +/- 11.4 years and 117.6 +/- 66.3 months, respectively. Half of the patients (50%) were smokers (mean 11.5 +/- 13.59 packs/year). The spirometric measurements of most of the patients were abnormal (40% restrictive, 30% obstructive respiratory disorder, 30% normal). The FEV3(L), predicted FEV1(%), FEF25(L), and predicted FEF25(%) values were significantly increased after the HD session. A positive correlation between BMI and Delta FEV3 (L) values (r = 0.377, P =.04) was observed. A significant improvement in FEV3 values after a single HD session was recorded, which was independently related to higher BMI (beta = 0.501, P <.01) and non-smoking (beta = 0.495, P <.05). Conclusion: Spirometric measurements are abnormal in most CHD patients, and a considerable improvement in pulmonary functions is possible with a single HD session. Having a high BMI and being a non-smoker appear to have significant positive effects on amelioration in FEV3 (L). Larger trials are needed to evaluate pulmonary functions in CHD patients
