Evaluation of patients with fibrotic interstitial lung disease: Preliminary results from the Turk-UIP study

OBJECTIVE: Differential diagnosis of idiopathic pulmonary fibrosis (IPF) is important among fibrotic interstitial lung diseases (ILD). This study aimed to evaluate the rate of IPF in patients with fibrotic ILD and to determine the clinical-laboratory features of patients with and without IPF that would provide the differential diagnosis of IPF. MATERIAL AND METHODS: The study included the patients with the usual interstitial pneumonia (UIP) pattern or possible UIP pattern on thorax high-resolution computed tomography, and/or UIP pattern, probable UIP or possible UIP pattern at lung biopsy according to the 2011 ATS/ERSARS/ALAT guidelines. Demographics and clinical and radiological data of the patients were recorded. All data recorded by researchers was evaluated by radiology and the clinical decision board. RESULTS: A total of 336 patients (253 men, 83 women, age 65.8 +/- 9.0 years) were evaluated. Of the patients with sufficient data for diag-nosis (n=300), the diagnosis was IPF in 121 (40.3%), unclassified idiopathic interstitial pneumonia in 50 (16.7%), combined pulmonary fibrosis and emphysema (CPFE) in 40 (13.3%), and lung involvement of connective tissue disease (CTD) in 16 (5.3%). When 29 patients with definite IPF features were added to the patients with CPFE, the total number of IPF patients reached 150 (50%). Rate of male sex (p<0.001), smoking history (p<0.001), and the presence of clubbing (p=0.001) were significantly high in patients with IPE None of the women <50 years and none of the men <50 years of age without a smoking history were diagnosed with IPE Presence of at least 1 of the symptoms suggestive of CTD, erythrocyte sedimentation rate (ESR), and antinuclear antibody (FANA) positivity rates were significantly higher in the non-IPF group (p<0.001, p=0.029, p=0.009, respectively). CONCLUSION: The rate of IPF among patients with fibrotic ILD was 50%. In the differential diagnosis of IPF, sex, smoking habits, and the presence of clubbing are important. The presence of symptoms related to CTD, ESR elevation, and EANA positivity reduce the likelihood of IPF

Multidrug resistance-1 gene C3435T single nucleotide polymorphism in OSAS patients

WOS: 000512905300018Aim: Obstructive sleep apnea syndrome (OSAS) is characterized by decreased airflow (hypopnea) or complete interruption (apnea) and is characterized by airway narrowing, decreased oxyhemoglobin saturation, hypercapnia, and hyperventilation associated therewith. It is known that genetic factors play role in the pathogenesis of OSAS. Multi-drug resistant-1 (MDR-1) gene products have a role in the pathogenesis of several diseases related to oxidative stress. We aimed to evaluate the frequency of MDR-1 gene C/T polymorphism in patients with OSAS. Material and Method: This study was performed on 43 OSAS and 23 healthy individuals. Blood samples from each individual were collected in tubes with ethylenediaminetetraacetic add (EDTA). DNA was extracted from the blood samples. The MDR-1 gene polymorphism was detected by polymerase chain reaction (PCR) and enzyme digestion techniques. Results: The frequencies of MDR-1 genotypes were found 27.9% for CC, 41.9% for CT and 30.2% for TT in the OSAS group and 17.4% for CC, 65.2% for CT and 17.4% for TT in the control group. The distribution of MDR-1 gene C alleles was found to be 48.8% in COPD group and 50.0% in the control group; T alleles were found to be 51.2% in OSAS group and 50.0% in the control group. There was no statistically significant difference observed between the groups for genotype and allele frequency of MDR-1 gene (p>0.05). Discussion: We believe these results can be useful for large-scale population genetic research considering the frequency of the MDR-1 gene variation in OSAS patients in the Turkish population

Mean Platelet Volume is Associated with Glycaemic Control and Retinopathy in Patients with Type 2 Diabetes Mellitus

Annakkaya, Ali Nihat N/0000-0002-7661-8830WOS: 000333443700007PubMed: 24756738Objectives: To investigate the relationship between mean platelet volume (MPV) and glycometabolic indices, to compare MPV according to HbA1c levels, and to analyse the difference in MPV between patients with and without microvascular complications. Methods: This retrospective study was conducted on 60 Type 2 diabetic patients and 50 age- and sex-matched non-diabetic controls. We obtained demographic, clinical and laboratory data including MPV platelet count, fasting and postprandial blood glucose (FBG and PBG), haemoglobin A1c (HbA1c), lipid profile, creatinine, systolic and diastolic blood pressure (BP) in patient and control groups, and diabetic microvascular complications including nephropathy, neuropathy, and retinopathy in the patient group. All analyses were performed using SPSS version 15.0 for Windows. Results: Mean platelet volume in the diabetic group was higher than in the control group (p = 0.001). Mean platelet volume was positively correlated with FBG and HbA1c levels (p = 0.03 and p 7% was significantly higher than those with HbA1c <= 7% (p < 0.001). Mean platelet volume was significantly increased in patients with retinopathy compared to those without retinopathy (p = 0.04). Conclusion: This study has shown that an increased MPV is closely associated with poor glycaemic control, which may be a risk factor for diabetic retinopathy. Nonetheless, further prospective studies are needed to assess the relationship between MPV, glycaemic indices and microvascular complications

Is the sleep perception of obstructive sleep apnea patients reliable? [Obstrüktif uyku apnesi hastalarının uyku algıları güvenilir mi?]

Aim: The aim of this study, is to evaluate the consistency with the polysomnography (PSG) data of the patients and the data reported by the patients themselves after PSG examination in the morning. Material and Methods: One hundred and thirty-four consecutive individuals who were admitted to the Chest Disease Polyclinic for Sleep Disorders of Duzce University Medical Faculty were included in the study. PSG and the questions related to sleep perception was applied by the same physician with face to face interview to all participants. Results: Of the patients included in the study 90 (67.2%) were male and 44 (32.8%) were female, and the mean age was 47.3±12.6 years. While there was a significant correlation (p=0.042, r=0.301) between the sleep time reported by the patients themselves after waking up in the morning and the sleep time measured by the PSG in patients without obstructive sleep apnea (OSA), there was no correlation in OSA (+) patients (p=0.269, r=0.125). Similarly, while there was a significant correlation (p=0.026, r=0.352) between the sleep latency reported by the patients themselves after waking up in the morning and the sleep latency measured by the PSG in OSA (-) patients, there was no correlation in OSA (+) patients (p=0.060, r=0.223). Conclusion: While evaluating OSA patients and explaining their treatment before and after PSG, it should be kept in mind that they might have impaired perception. Therefore, we thought that we should spend more time to patients, and to make our explanations more clearly and understandably. © 2019, Duzce University Medical School. All rights reserved

Effects of cruroraphy and laparoscopic Nissen fundoplication procedures on pulmonary function tests in gastroesophageal reflux patients

Annakkaya, Ali Nihat N/0000-0002-7661-8830WOS: 000333151800015PubMed: 24600501Gastroesophageal reflux disease plays a role in the etiology of asthma, chronic bronchitis, aspiration pneumonia, bronchiectasis and interstitial lung fibrosis by affecting the upper respiratory system. To investigate the changes in pulmonary function tests in patients who underwent cruroraphy and laparoscopic Nissen fundoplication for gastroesophageal reflux disease. Between January and October of 2012, cruroraphy and laparoscopic Nissen fundoplication have been carried out on 40 patients with gastroesophageal reflux disease in the Department of General Surgery, Faculty of Medicine, Duzce University. Patients had pulmonary function tests were measured preoperatively and on postoperative day 20. Increases in forced vital capacity, forced expiratory volume in 1 second/forced vital capacity and forced expiratory flow between 25-75% of vital capacity were observed postoperatively in all patients and these increases were found to be statistically significant (p=0.001). Change in the forced expiratory volume in 1 second was not statistically significant (p=0.182). We conclude that treatment of reflux in early stages by surgical procedures could prevent development of chronic lung disease by safeguarding the pulmonary system functions
