Decreasing Rate of Unknown Bronchiectasis Etiology: Evaluation of 319 Adult Patients with Bronchiectasis

OBJECTIVE: Bronchiectasis can have several causes, but there are only a limited number of studies about the prevalence of these causes. Most of the studies in adults are from previous years. This study aimed to identify etiologies in adult patients with bronchiectasis

The natural course of progressive systemic sclerosis patients with interstitial lung involvement

Objective: The aim of the study is to assess the natural course of systemic sclerosis (SSc) in patients with interstitial lung involvement and to evaluate the effects of treatment. Materials and methods: Sixty SSc patients with interstitial lung involvement were included in the study and history and retrospective data records of the patients were reviewed. Results: It was observed that 47 patients (78.3%) had Raynaud's phenomenon, 7 patients (11.7%) had skin involvement, 5 patients (8.3%) had joint involvement, and 1 patient (1.7%) had gastrointestinal system involvement as the first manifestation of the disease. Lung involvement had developed on an average of 113 +/- 106 months after the first manifestation of the disease and was apparent within the first year in 10 patients (16.7%), between 1 and 2 years in 3 patients (5%), between 2 and 3 years in 2 patients (3.3%), between 3 and 4 years in 5 patients (8.3%), between 4 and 10 years in 21 patients (35%), and after 10 years in 19 patients (31.7%). When the symptoms of lung involvement appeared, 37 patients (61.7%) were not receiving treatment while 23 (38.3%) were using an immunosuppressive agent. The time interval of lung involvement for the treated patients was 131 +/- 95 months while it was 101 +/- 112 months in untreated patients (p > 0.05). Conclusion: In SSc patients with intersititial pulmonary involvement, the disease frequently starts with Raynaud's phenomenon and pulmonary symptoms tend to appear at a mean of 7 years after the onset of disease. The first sign of the disease, the probability of interstitial pulmonary involvement, is highest during the first 15 years after. Although this probability decreases after 15 years, in up to 10% of the patients, interstitial pulmonary involvement can still occur even up to 40 years. Immunosuppressive treatment is not effective in preventing the development of pulmonary involvement. However, it delays the manifestation of pulmonary symptoms for nearly 4 years

Investigating the Differences in Polysomnography Results Evaluated According to the Recommended and Alternative Hypopnea Criteria Utilized in the Evaluation of Polysomnography

OBJECTIVE: The criteria of hypopnea recommended by the American Academy of Sleep Medicine until 2012 was 3% desaturation and 50% decline in the signal amplitude. The recommended and alternative criteria for hypopnea were determined as 3% desaturation accompanied by a 30% decline in the signal amplitude and 4% desaturation accompanied by a 30% decline in the amplitude by the 2013 update of the guideline was published by the American Academy of Sleep Medicine in 2012. The objective of our study was to investigate to what degree scoring of hypopneas has great importance in the diagnosis and severity grading of obstructive sleep apnea syndrome according to different criteria. MATERIAL AND METHODS: The present study was designed as a retrospective study in which the results of the polysomnography of 62 patients were recorded after evaluation according to 3 different hypopnea criteria. Criteria 1, criteria 2, and criteria 3 were accepted as a 3% drop in SaO 2 accompanied by a 30% decline in the amplitude, as a 4% drop in SaO 2 accompanied by a 30% decline in the amplitude, and as a 3% drop in SaO 2 accompanied with a 50% decline in the amplitude, respectively. RESULTS: Statistically significant differences were determined between criteria 1 and criteria 2, criteria 1 and criteria 3, and criteria 2 and criteria 3 regarding the numbers of hypopneas. CONCLUSION: For the same polysomnography, evaluations with different accepted hypopnea criteria cause different polysomnography results

Comparison of the effectiveness of cyclophosphamide and rituximab treatment in patients with systemic sclerosis-related interstitial lung diseases: a retrospective, observational cohort study

Objectives To compare the effectiveness of cyclophosphamide and rituximab in the treatment of patients with systemic sclerosis with pulmonary involvement (SSc-ILD)

The frequency of obstructive sleep apnea in patients with primary Sjogren's syndrome

Introduction There is a lack of information about the frequency of obstructive sleep apnea (OSA) in primary Sjogren's syndrome (pSS). Using all-night polysomnography (PSG), this study aimed to investigate the frequency of OSA in pSS and the factors affecting the frequency of OSA in this condition

Maternal and Fetal Problems in Patients with Non-Cystic Fibrosis Bronchiectasis During Pregnancy

OBJECTIVE: To detect the maternal and fetal problems experienced by patients with non-cystic fibrosis (non-CF) bronchiectasis during pregnancy

The Frequency of Obstructive Sleep Apnea in Patients with Non-cystic Fibrosis Bronchiectasis

OBJECTIVE: Interruption or reduction in airflow and desaturation is a theoretically expected result in bronchiectasis accompanied by excessive secretions in the airways, bronchial wall thickening, and destruction of the wall structure. The same mechanism of interruption or reduction in airflow and desaturation is valid for obstructive sleep apnea (OSA). However, data on the association of bronchiectasis with OSA are scarce. We aimed to investigate the frequency of OSA and related parameters in patients with non-cystic fibrosis bronchiectasis (NCFB)
