In this prospective study of consecutive patients with suspected ARVD/C evaluated by a standard protocol including biopsy, the incidence of cardiac sarcoid was surprisingly high (15%). Clinical features, with the exception of left ventricular dysfunction and histological findings, did not discriminate between the two entities.

Background Gastroesophageal reflux disease (GERD) is thought to be a risk factor for the development or progression of chronic rejection after lung transplantation. However, the prevalence of GERD and its risk factors, including esophageal dysmotility, hiatal hernia and delayed gastric emptying after lung transplantation, are still unknown. In addition, the prevalence of Barrett’s esophagus, a known complication of GERD, has not been determined in these patients. The purpose of this study was to determine the prevalence and extent of GERD, as well as the frequency of these risk factors and complications of GERD in lung transplant patients. Methods Thirty-five consecutive patients underwent a combination of esophageal function testing, upper endoscopy, barium swallow, and gastric emptying scan after lung transplantation. Results In this patient population, the prevalence of GERD was 51% and 22% in those who had been retransplanted. Of patients with GERD,36% had ineffective esophageal motility (IEM), compared with 6% of patients without GERD (P = .037). No patient demonstrated hiatal hernia on barium swallow. The prevalence of delayed gastric emptying was 36%. The prevalence of biopsy-confirmed Barrett’s esophagus was 12%. Conclusion Our study shows that, after lung transplantation, more than half of patients had GERD, and that GERD was more common after retransplantation. IEM and delayed gastric emptying are frequent in patients with GERD. Hiatal hernia is rare. The prevalence of Barrett’s esophagus is not negligible. We conclude that GERD is highly prevalent after lung transplantation, and that delayed gastric emptying and Barrett’s esophagus should always be suspected after lung transplantation because they are common risks factors and complications of GERD.

In our lung transplant recipient cohort, GCV levels were subtherapeutic in all patients with persistent suboptimal response to GCV, each of whom had GCV-R CMV infection. In contrast, GCV levels were therapeutic in CMV-infected patients with delayed GCV response.

Background Although gastroesophageal reflux disease (GERD) is highly prevalent in lung transplantation, the pathophysiology of GERD in these patients is unknown. We hypothesize that the pathophysiology of GERD after lung transplantation differs from that of a control population, and that the 30-d morbidity and mortality of laparoscopic antireflux surgery (LARS) are equivalent in both populations. Methods We retrospectively compared the pathophysiology of GERD and the 30-d morbidity and mortality of 29 consecutive lung transplant patients with 23 consecutive patients without lung transplantation (control group), all of whom had LARS for GERD between November 2008 and May 2010. Results Both groups had a similar prevalence of endoscopic esophagitis and Barrett’s esophagus, comparable manometric profiles, and similar prevalence of abnormal peristalsis. However, hiatal hernia was more common in controls than in lung transplant patients (57% versus 24%; P = 0.04). Lung transplant patients had a higher prevalence and severity of proximal GERD (65% versus 33%; P = 0.04). The 30-d morbidity and mortality following LARS were similar in both groups regardless of the higher surgical risk of lung transplants (median ASA class: 3 versus 2 for controls, P < 0.001). Conclusions These results show that despite similar manometric profiles, lung transplant patients are more prone to proximal reflux than the general population with GERD; the prevalence of endoscopic esophagitis and Barrett’s esophagus is the same in both groups of patients; a hiatal hernia is uncommon after lung transplantation; and the morbidity and mortality of LARS are the same for lung transplant patients as the general population with GERD.
