Abstract
Lung transplantation is a well-established treatment for children facing advanced lung disease and pulmonary vascular disorders. However, organ shortage remains highest in children. For fitting the small chest of children, transplantation of downsized adult lungs, lobes, or even segments were successfully established. The worldwide median survival after pediatric lung transplantation is currently 5.7 years, while under consideration of age, underlying disease, and peri- and posttransplant center experience, median survival of more than 10 years is reported. Timing of referral for transplantation, ischemia-reperfusion injury, primary graft dysfunction, and acute and chronic rejection after transplantation remain the main challenges.

Abstract
BACKGROUND Due to the complex therapy and the required high level of immunosuppression, lung recipients are at high risk to develop many different long term complications. METHODS From 1993-2000, a total of 54 lung transplantation (LuTx) were performed at our center. Complications, graft and patient survival of this cohort was retrospectively analyzed. RESULTS One/five and ten-year patient survival was 71.4%, 41.2% and 25.4%; at last follow up (4/2010), twelve patients were alive. Of the 39 deceased patients, 26 died from infectious complications. Other causes of death were myocardial infarction (n=1), progressive graft failure (n=1), intracerebral bleeding (n=2), basilary vein thrombosis (n=1), pulmonary emboli (n=1), others (n=7). Surgical complication rate was 27.7% during the first year and 25% for the 12 long term survivors. Perioperative rejection rate was 35%, and 91.6% for the 12 patients currently alive. Infection incidence during first hospitalization was 79.6% (1.3 episodes per transplant) and 100% for long term survivors. Commonly isolated pathogens were cytomegalovirus (56.8%), Aspergillus (29.4%), RSV (13.7%). Other common complications were renal failure (56.8%), osteoporosis (54.9%), hypertension (45%), diabetes mellitus (19.6%). CONCLUSIONS Infection and rejection remain the most common complications following LuTx with many other events to be considered.

Abstract
PURPOSE OF REVIEW Lung transplantation for infants and children is an accepted but rarely exercised option for the treatment of end-stage lung disease, with outcomes equivalent to those for adults. However, widespread misconceptions regarding pediatric outcomes often confound timely and appropriate referral to specialty centers. We present the updated information for primary pediatricians to utilize when counseling families with children confronted by progressive end-stage pulmonary or cardiovascular disease. RECENT FINDINGS We provide general guidelines to consider for referral, and discuss allocation of organs in children, information regarding standard treatment protocols, and survival outcomes. SUMMARY Lung transplantation is a worthwhile treatment option to consider in children with end-stage lung disease. The treatment is complex, but lung transplant provides substantial survival benefit and markedly improved quality of life for children and their families. This timely review provides comprehensive information for pediatricians who are considering options for treatment of children with end-stage lung disease.

The Role of Infections in BOS. BRONCHIOLITIS OBLITERANS SYNDROME IN LUNG TRANSPLANTATION 2013.

Abstract
Background: Infectious agents, particularly cytomegalovirus (CMV), have long been considered to be potential triggers for BOS, although the exact magnitude of the role of infections and the mechanisms thereof remain an area of active research. Methods: This chapter will review previous literature and newer results concerning the possible roles of CMV, other herpesviruses, community-acquired respiratory viruses, bacteria (including Pseudomonas, other gram-negative, gram-positive, and atypical organisms), and fungi, including colonization as well as invasive infection. Results: The text reviews and evaluates the body of literature supporting a role for these infectious agents as risk factors for BOS and time to BOS. Changing patterns of infection over time are taken into account, and studies that have shown an association between BOS (or lack thereof) and CMV are reviewed. Strategies for prevention or early treatment of infections are discussed as potential means of preserving allograft function long term. Immunizations, stringent infection-control practices, and antimicrobial treatment including newer therapies will be discussed. Conclusion: In addition to the classic literature that has focused on CMV, an expanding spectrum of infectious organisms has been implicated as possible risk factors for BOS. Increasing knowledge of the impact of long-term antiviral suppression, prophylaxis, and outcomes of early therapy will help guide future recipient management.

Abstract
Seventy-six cytomegalovirus (CMV)-seropositive lung transplant recipients receiving valganciclovir (900 mg/day) for CMV prophylaxis were compared with a group of 87 patients receiving oral ganciclovir (3000 mg/day). Prophylaxis was administered to day 120 post-transplantation and follow-up was 1 year. In addition, a study was conducted on risk factors for CMV infection/disease. CMV disease incidence was 7.9% and 16.1% for valganciclovir and oral ganciclovir, respectively (p = 0.11). Patients receiving valganciclovir had fewer viral syndromes (2.6% vs. 11.5%, p < 0.05), a similar rate of tissue-invasive disease (5.2% vs. 4.6%, p = ns), longer time-to-onset of CMV infection/disease (197.5 vs. 155.2 days, p < 0.05), and a lower probability of infection/disease while on prophylaxis (1.3% vs. 12.6%, p < 0.01). Nonetheless, leukopenia incidence was higher with valganciclovir (15.8% vs. 2.3%, p < 0.01), as was the need for treatment withdrawal due to adverse effects (11.8% vs. 1.1%, p < 0.01). CMV infection was similar in both groups (32.9% vs. 34.5%). Induction therapy with basiliximab and glucocorticosteroid treatment were independent risk factors for developing CMV infection/disease. In conclusion, valganciclovir prophylaxis results in a low incidence of CMV disease in lung transplant recipients and appears more effective than oral ganciclovir. Despite the comparatively higher incidence of adverse events with valganciclovir, the drug can be considered safe for prophylaxis.

J Heart Lung Transplant 2008; 27:875-81.

Abstract
BACKGROUND Universal ganciclovir (GCV) prophylaxis is a strategy aimed at reducing cytomegalovirus (CMV) infection and delaying the development of bronchiolitis obliterans syndrome (BOS). However, the optimal duration of GCV prophylaxis remains unclear. We report our experience with GCV prophylaxis administered indefinitely and its effect on CMV pneumonitis, BOS and survival after lung transplantation (LT). METHODS One hundred fifty-one patients surviving >100 days after LT were analyzed. GCV was given to 130 CMV donor- or recipient-seropositive patients. Data from 90 patients who received indefinite GCV prophylaxis (IND) and 40 patients who discontinued their GCV prophylaxis (STOP) were compared. RESULTS CMV pneumonitis occurred in 16%, 8%, 17% and 19% of patients in the D+R+, D-R+, D+R- and D-R- groups, respectively. In the STOP cohort, 15 of 40 patients developed CMV pneumonitis (median time 79 days) after GCV was stopped. Ten of these 15 patients developed BOS (median time 116 days) after discontinuing GCV. The risk of CMV pneumonitis in the STOP cohort was significantly higher when GCV prophylaxis was discontinued within the first year. Cumulative incidence of CMV pneumonitis in the IND and STOP groups at 5 years was 2% and 57%, respectively (p < 0.001). BOS-free survival and survival were similar across both groups. CONCLUSIONS Indefinite GCV prophylaxis prevents CMV pneumonitis in 98% of LT recipients. Thirty-eight percent of patients discontinuing prophylaxis developed CMV pneumonitis, 50% of whom progressed to BOS within 1 year. Continuing ganciclovir prophylaxis indefinitely after lung transplantation should be considered.
