Background: Acute exacerbation of chronic fibrotic idiopathic interstitial pneumonia (AE-IIP) is associated with a high mortality rate. In 2016, the International Working Group classified the etiology of AE-IIP into idiopathic and triggered. Several factors can trigger AE-IIP; however, the triggers associated with the worst prognosis have not been identified. The aim of this study was to investigate the prognosis of patients with various types of AE-IIP, particularly infection-triggered, non-infection-triggered, and idiopathic AE-IIPs. Methods: We retrospectively collected data for 128 patients with chronic fibrotic IIP (CF-IIP) who were hospitalized because of respiratory failure during the period between April 2009 and March 2019 at Juntendo University Hospital. There were 79 patients who developed AE-IIP, and 21 patients who developed bacterial pneumonia combined with CF-IIP. AE-IIP was classified into idiopathic, infection-triggered, and non-infection-triggered. We analyzed differences in patient characteristics, examination findings, and prognosis among the types. Finally, we evaluated risk factors for early death due to AE-IIPs. Results: Idiopathic, infection-triggered, and non-infection-triggered AE-IIPs were diagnosed in 34, 25, and 20 patients, respectively. The survival time was significantly longer for bacterial pneumonia combined with IIP than for AE-IIP. Moreover, the survival time was significantly longer for infection-triggered AE-IIP than for idiopathic or non-infection-triggered AE-IIP. The mortality rate was significantly lower with infection-triggered AEIIP than with other types of AE-IIP. Finally, a multivariate analysis revealed that radiological findings at the time of onset of AE-IIPs and AE-IIP patterns were independent risk factors for early death. Conclusion: Our results suggest that patients with infection-triggered AE-IIP may have a better prognosis than those with other types of AE-IIP.

Background/Aims: Helicobacter pylori infection causes gastritis, peptic ulcers and gastric malignancies, and its eradication has been advocated by many groups. We determined the H. pylori carrier status and eradication rates of patients with chronic hepatitis C virus (HCV) infection. Methods: In total, 76 chronically HCV-infected patients were enrolled for comparison with 228 HCV-noninfected, age- and sex-matched controls. H. pylori infection was confirmed by H. pylori antibody and urea breath testing. Results: The H. pylori infection rate was significantly higher for HCV-infected patients (67 of 76, 88.2%) than for HCV-noninfected controls (158 of 228, 69.3%). Endoscopic fi ndings showed that the rates of gastric ulcers and gastritis were significantly higher for the 67 HCV-infected patients with H. pylori infection (34.3% and 77.6%) than for the 158 HCV-noninfected controls with H. pylori infection (15.2% and 57.6%). Treatment to eradicate H. pylori had a signifi cantly higher success rate for HCV-infected patients (61 of 67, 91.0%) than for HCV-noninfected controls (115 of 158, 72.8%). Conclusions: The markedly high H. pylori eradication rate observed in this study shows that eradication of H. pylori holds promise for the improvement of the long-term health condition of patients with chronic HCV infection.
