Antifibrotics and lung transplantation: A Spanish multicentre case-controlled study.

BACKGROUND AND OBJECTIVE: Antifibrotic drugs are the standard treatments for patients with idiopathic pulmonary fibrosis (IPF). This study aims to assess the safety of antifibrotic treatment in IPF patients undergoing lung transplantation. METHODS: Patients with a diagnosis of IPF who received a lung transplant between January 2015 and June 2019 at four Spanish hospitals specialized in lung transplantation were retrospectively recruited. Cases were defined as patients receiving antifibrotic treatments at time of transplant. Each case was matched with a control who did not receive antifibrotic treatment. RESULTS: A total of 164 patients were included in the study cohort (103 cases and 61 controls). There were no statistically significant differences between the cases and controls in any of the items studied related to transplantation except the time until the appearance of chest wall dehiscence: although there were no differences in the incidence of wall dehiscence in either group (12.3% vs. 13.7%; p = 0.318), the patients on antifibrotic drugs experienced it earlier (21 days [IQR = 12.5-41.5] vs. 63 days [IQR = 46.75-152.25]; p = 0.012). There were no differences in overall post-transplant survival between the two groups (p = 0.698) or in conditional survival at 30 days, 90 days, 3 years or 5 years. However, 1 year survival was significantly greater among controls (80.6% vs. 93.3%; p = 0.028). CONCLUSION: There was evidence that chest wall dehiscences appeared earlier post-transplant in patients using antifibrotics, even though this factor did not significantly impact survival.

Morbidity and mortality of serious gastrointestinal complications after lung transplantation.

BACKGROUND: Gastrointestinal complications after lung transplatation are associated with an increased risk of morbidity and mortality. This study aims to describe severe gastrointestinal complications (SGC) after lung transplantation. METHODS: We performed a prospective, observational study that included 136 lung transplant patients during a seven year period in a tertiary care universitary hospital. SGC were defined as any diagnosis related to the gastrointestinal or biliary tract leading to lower survival rates or an invasive therapeutic procedure. Early and late complications were defined as those occurring < 30 days and ≥ 30 days post-transplant. The survival function was calculated through the Kaplan-Meier estimator. Variables were analyzed using univariate and multivariate analysis. Statistical significance was defined as p < 0.05. RESULTS: There were 17 (12.5%) SGC in 17 patients. Five were defined as early. Twelve patients (70.6%) required surgical treatment. Mortality was 52.9% (n = 9). Patients with SGC had a lower overall survival rate compared to those who did not (14 vs 28 months, p = 0.0099). The development of arrhythmias in the first 48 h of transplantation was a risk factor for gastrointestinal complications (p = 0.0326). CONCLUSIONS: SGC are common after lung transplantation and are associated with a considerable increase in morbidity-mortality. Early recognition is necessary to avoid delays in treatment, since a clear predictor has not been found in order to forecast this relevant comorbidity.

Treatment of bronchus intermedius stenosis in lung transplantation with Montgomery T-tube stent. A novel technique.

Airway complications after lung transplant are relatively common although the rates vary according to the different studies. Pathogenesis is diverse but the principal mechanism is usually bronchus intermedius ischemia in the post-transplant period. One major complication is bronchial stenosis, with relatively frequent involvement of the bronchus intermedius in the case of right lung transplantation. Various treatments have been proposed for bronchus intermedius stenosis, such as endobronchial balloon dilation, laser, cryosurgery and bronchial stents. We present two cases of lung transplant recipients with bronchus intermedius stenosis treated with a Montgomery stent or T-stent, commonly used for tracheal stenosis, who showed positive clinical and functional response.

Recommendations of diagnosis and treatment of pleural effusion. Update.

Although during the last few years there have been several important changes in the diagnostic or therapeutic methods, pleural effusion is still one of the diseases that the respiratory specialist have to evaluate frequently. The aim of this paper is to update the knowledge about pleural effusions, rather than to review the causes of pleural diseases exhaustively. These recommendations have a longer extension for the subjects with a direct clinical usefulness, but a slight update of other pleural diseases has been also included. Among the main scientific advantages are included the thoracic ultrasonography, the intrapleural fibrinolytics, the pleurodesis agents, or the new pleural drainages techniques.
