BACKGROUND Acute exacerbation of chronic fibrosing interstitial pneumonia (AE-CFIP) is an often fatal condition with no established treatment. Recently, macrolides were found to be beneficial in cases of acute lung injury. OBJECTIVES To examine the clinical effectiveness and safety of intravenous azithromycin in patients hospitalized for AE-CFIP. METHODS A prospective, open-label study with historical controls was conducted. Twenty consecutive patients with AE-CFIP received azithromycin. They were compared with a historical cohort treated with fluoroquinolone (n = 56). All patients received high-dose steroid pulse therapy. The primary end point was mortality at 60 days. The secondary end point was safety of intravenous azithromycin in patients with AE-CFIP. Inverse probability of treatment weighting (IPTW) using the propensity score was performed to investigate the relationship between azithromycin use and survival time. RESULTS Mortality was significantly lower in the patients treated with azithromycin than in those treated with fluoroquinolone (mortality rate at 60 days: 20 vs. 69.6%, p < 0.001; median survival time: not reached vs. 29.5 days, p < 0.001). The IPTW adjusted hazard of mortality at 60 days in patients receiving azithromycin was 0.17 (95% CI 0.05-0.61). No serious adverse events were observed. CONCLUSIONS Azithromycin was associated with improved outcomes in patients with AE-CFIP. Further studies are needed to verify this finding (Clinical trial JMA-IIA00095).

The latter conclusion is based on a metaanalysis of 13 randomized controlled trials that did not show statistically significantly better eff...

Nonspecific Interstitial pneumonia (NSIP)/ Overlap or Distinct Entity: A case report from the National Research Institute of Tuberculosis and Lung Disease (NRITLD)

Background: In many cases of ILD (interstitial lung disease), overlap diagnosis is considered. Here, a few cases with diagnosis of a variety of ILDs, where eventual open lung biopsy has been performed are selected. Reference will be made to reliable sources to show that NSIP can still be a variant of UIP (Usual interstitial pneumonia) with better treatment response and prognosis. Case Presenta...

Impact of lymphocyte differential count > 15% in BALF on the mortality of patients with acute exacerbation of chronic fibrosing idiopathic interstitial pneumonia

BACKGROUND Chronic fibrosing idiopathic interstitial pneumonia (CFIIP) has a potential risk of acute exacerbation (AE). However, the usefulness of cellular analysis of bronchoalveolar lavage fluid (BALF) has never been evaluated. This study aimed to evaluate the impact of the lymphocyte differential count > 15% in BALF on the mortality of patients with AE of CFIIP. METHODS We retrospectively ...
