- ItemInvestigation of pepsin levels in bronchial lavage in patients with interstitial lung disease and chronic cough(Elsevier, 2024-11) Ala Çitlak, Fatma Selen; Köksal, Nurhan; Avci, Bahattin; Tibel Tuna, Nazmiye; Güllü, Yusuf Taha; 156045Aim: Pepsin is an enzyme that helps digest protein secreted only from the gastric chief cell in an inactive state. Pepsin is a good marker for acidic gastroesophageal reflux (GER). Its presence in sputum or saliva is considered pathologic. In GER, cough is stimulated by broncho-esophageal neurogenic reflex and aspiration of gastric contents into the airways. GER is the most common cause of cough. Gastric acid reflux is also thought to play a role in Interstitial Lung Disease (ILD) etiology. In many studies, pepsin and bile acid levels in bronchial lavage were high in patients with interstitial lung disease and chronic cough. In our study, we aimed to evaluate pepsin levels in bronchial lavage in patients with ILD and chronic cough and to investigate the relationship between symptoms and reflux treatment. Methods: Between January 2021 and February 2022, 212 patients who underwent bronchoscopy in our tertiary clinic were evaluated. These patients were divided into three groups: 52 patients with interstitial lung disease, 81 patients with chronic cough, and 79 patients who underwent bronchoscopy with a pre-diagnosis of lung cancer as the control group. Bronchial lavage obtained by bronchoscopy was analyzed for pepsin levels. Results: Shortness of breath and cough were the most common symptoms in all three groups. Pepsin levels were 16.71 ± 8.6 ng/ml in the chronic cough group, 15.6 ± 8.9 ng/ml in the ILD group, and 10.58 ± 5.4 ng/ml in the lung cancer (control) group. Pepsin levels in the ILD and chronic cough group were statistically significantly higher than in the lung cancer group (p:0.00). There was no statistical difference between the ILD group and the chronic cough group regarding pepsin levels. It was found that pepsin levels were lower in the three groups who received anti-reflux treatment. There was no difference in pepsin levels between ILD subgroups. Conclusion: Pepsin levels in bronchial lavage were higher in the ILD and chronic cough groups. This suggests that reflux may be involved in the etiology of chronic cough and ILD. Low pepsin values in patients receiving antireflux therapy have shown that occult reflux may occur. In our study, the high level of pepsin in bronchial lavage, especially in the chronic cough and ILD group, may be instructive in the etiology and treatment planning of the disease.
- ItemOutcomes of Liver Transplantation in Infants: A Retrospective Cohort Study(Elsevier, 2024-12) Erbiş, Halil; Kılınç, Eyyüp Mehmet; Fırat, Aynur; Aliosmanoğlu, Çiğdem; Ağca, Mevlüt Harun; Aliosmanoğlu, İbrahim; 104930Background. Liver transplantation (LT) is a crucial treatment for infants with end-stage liver disease, yet specific data on LT outcomes in infants under 12 months old remain limited. This study aims to present the clinical course and outcomes of infants who underwent LT, assessing the impact of demographic and etiological differences on mortality and survival. Methods. A retrospective analysis was conducted on 64 infants (< 12 months) who underwent LT between January 2019 and March 2024. Demographic, clinical, and laboratory data were collected from their medical records. LT-specific details, postoperative complications, and survival data were analyzed. Results. The median age of the infants was 157 days, with 37 boys (57.8%) and 27 girls (42.2%). Biliary atresia was the most common diagnosis (85.9%), and seven infants had undergone a previous Kasai procedure. The median pediatric end-stage liver disease (PELD) score was 15.5. Left lateral segmentectomy was the predominant graft type (60.9%). The median pediatric intensive care unit (PICU) and hospital stays were 5 and 21 days, respectively. Complications occurred in 20 infants (31.3%), with vascular and biliary complication rates both at 12.5%. The overall mortality rate was 17.2%, with early (30-day) and late mortality rates of 6.3% and 10.9%, respectively. The median overall survival (OS) was 204.5 days, and the 1-year survival rate was 32.8%. Kaplan-Meier and log rank analyses showed no significant impact of sex, age, diagnostic groups, graft type, or surgical complications on OS (P> .05). Conclusions. LT in infants can be performed with acceptable morbidity and mortality rates, particularly with increased experience and standardized protocols.
