Abstract
BACKGROUND Bronchiolitis obliterans organising pneumonia is a rare complication associated with calcineurin inhibitors and mammalian target of rapamycin inhibitors. While bronchiolitis obliterans organising pneumonia in adult transplant patients has been reported, it has not been well described in pediatric transplant patients. CASE DESCRIPTION We present a case of a 19-month-old male patient with dilated cardiomyopathy who underwent orthotropic heart transplantation at 14 months of life for heart failure refractory to medical therapy. Approximately 4 months post-transplant, he presented with diarrhea and vomiting with acute kidney injury secondary to dehydration. His tacrolimus level on admission and first week of hospitalisation was within target range of 10-12 ng/ml. He was diagnosed with esophagitis and prescribed proton pump inhibitors. Our patient subsequently developed significant respiratory distress with initial chest radiograph showing right lower lobe opacities. Repeat tacrolimus at the time of worsening respiratory status was 84.2 ng/dL and his tacrolimus was held. He required intubation due to significant hypoxia with progression of lung to disease and development of diffuse bilateral opacities consistent with acute respiratory distress syndrome. Despite initiation of steroids and aggressive ventilator management, he continued to be hypoxic on maximal respiratory support. After 28 days post admission, support was withdrawn. On autopsy, his lung biopsy findings were consistent with bronchiolitis obliterans organising pneumonia. CONCLUSION Life-threatening bronchiolitis obliterans organising pneumonia can be seen in pediatric transplant patients on tacrolimus or when transitioning from tacrolimus to sirolimus, highlighting the need for close monitoring of heart transplant patients on immunosuppressive medications presenting with hypoxia.

Abstract
Sirolimus is an immunosuppressive medication often used in solid organ transplantation. It has been associated with severe side effects, including pulmonary toxicity. In adult patients, a single center study found that 14% of those treated with sirolimus developed pulmonary pneumonitis; however, the incidence in the pediatric population is not known. Most reports in adult patients indicate that elevated drug concentrations and a prolonged duration of use are associated with pulmonary toxicity. We report a case of a 17-year-old male kidney transplant recipient who developed rapid-onset respiratory failure, necessitating mechanical ventilation and acute renal replacement therapy for ultrafiltration secondary to sirolimus-induced pneumonitis. He had been treated for acute rejection with corticosteroids 17 days prior to the development of pneumonitis. His symptoms developed within 1 week of initiation of sirolimus and with a serum concentration of 1.1 ng/mL. Sirolimus was discontinued, and, following aggressive diuresis and ventilatory support, his respiratory status returned to baseline. Sirolimus-induced pneumonitis is an important diagnosis to be considered in any transplant recipient receiving sirolimus with new onset fever, cough, or dyspnea without an identifiable source, especially if there is a preceding history of treatment with high-dose corticosteroids.

Abstract
Pulmonary complications following solid organ transplantation are common and often infectious in nature. Articles describing noninfectious pulmonary complications overwhelmingly rely on clinical and radiographic data. There are a limited number of studies with companion histology delineating the clinical diagnoses of pulmonary complications. This contrasts with blood and bone marrow transplantations. Using a retrospective cohort approach, the current study aimed to assess antemortem and postmortem pulmonary findings in solid organ transplantation recipients. Medical records and autopsy materials from 92 solid organ transplantation recipients were reviewed. Pulmonary complications were identified in 70 patients (76%). For patients with pulmonary complications at autopsy the mean survival posttransplantation was 3.48 years as compared to 7.29 years for patients without pulmonary complications at autopsy (P = .01). Twenty-eight infectious complications (fungal pneumonia, n = 20; cytomegalovirus pneumonia, n = 7; bacterial pneumonia, n = 1) and 113 noninfectious pulmonary complications were identified. The most common noninfectious findings were diffuse alveolar damage (n = 32), organizing pneumonia (n = 31), and pulmonary thromboemboli (n = 26). Disseminated infections and respiratory failure were the most common immediate causes of death (n = 24 and n = 23, respectively). Most noninfectious complications were not diagnosed antemortem.

Abstract
BACKGROUND Sirolimus is immunosuppressive drug used to prevent rejection in kidney transplantation. Pulmonary problems are one of the serious complications which may be seen after administration of this drug and it is believed that it could be life threatening. CASE PRESENTATION Here in this paper we presented a 49-years-old man with bronchiolitis obliterans organizing pneumonia (BOOP) induced by chronic use of Sirolimus. The disease was diagnosed and successfully treated. CONCLUSIONS Sirolimus uses after kidney transplantation may lead to lung complications, especially BOOP, and the prompt diagnosis would allow earlier treatment.

Abstract
Background Two novel mammalian targets of rapamycin (mTOR) inhibitors everolimus and temsirolimus are now approved by regulatory agencies and have been widely investigated among various types of solid tumors, but the risk of fatal adverse events (FAEs) with these drugs is not well defined. Methods We searched PubMed, EMBASE, and Cochrane library databases for relevant trials. Eligible studies included prospective phase II and III trials evaluating everolimus and temsirolimus in patients with all malignancies and data on FAEs were available. Statistical analyses were conducted to calculate the summary incidence, RRs and 95% confidence intervals (CIs) by using either random effects or fixed effect models according to the heterogeneity of the included studies. Results A total of 3322 patients with various advanced solid tumors from 12 trials were included. The overall incidence of mTOR inhibitors associated FAEs was 1.8% (95%CI: 1.3–2.5%), and the incidences of everolimus related FAEs were comparable to that of temsirolimus (1.7% versus 1.8%). Compared with the controls, the use of mTOR inhibitors was associated with an increased risk of FAEs, with a RR of 3.24 (95%CI: 1.21–8.67, p = 0.019). On subgroup analysis, a non-statistically significant increase in the risk of FAEs was found according to different mTOR inhibitors, tumor types or controlled therapy. No evidence of publication bias was observed. Conclusion With the present evidence, the use of mTOR inhibitors seems to increase the risk of FAEs in patients with advanced solid tumors. More high quality trials are still needed to investigate this association.

Abstract
OBJECTIVES Immunosuppressive pharmacologic agents prescribed to patients with diffuse interstitial and inflammatory lung disease and lung transplant recipients are associated with potential risks for adverse reactions. Strategies for minimizing such risks include administering these drugs according to established, safe protocols; monitoring to detect manifestations of toxicity; and patient education. Hence, an evidence-based guideline for physicians can improve safety and optimize the likelihood of a successful outcome. To maximize the likelihood that these agents will be used safely, the American College of Chest Physicians established a committee to examine the clinical evidence for the administration and monitoring of immunosuppressive drugs (with the exception of corticosteroids) to identify associated toxicities associated with each drug and appropriate protocols for monitoring these agents. METHODS Committee members developed and refined a series of questions about toxicities of immunosuppressives and current approaches to administration and monitoring. A systematic review was carried out by the American College of Chest Physicians. Committee members were supplied with this information and created this evidence-based guideline. CONCLUSIONS It is hoped that these guidelines will improve patient safety when immunosuppressive drugs are given to lung transplant recipients and to patients with diffuse interstitial lung disease.

Abstract
PURPOSE Sirolimus is a potent immunosuppressive agent used with increasing frequency in kidney transplantation. However, sirolimus can increase the rate of unexplained interstitial pneumonitis. The aim of this study was to evaluate the clinical characteristics of sirolimus-induced pneumonitis and the therapeutic results in renal transplant recipients. PATIENTS AND METHODS Seventy-two patients received sirolimus, conversion or de novo regimen, at our center between January 2007 and April 2011. Twelve of the 72 patients (16.7%) developed interstitial pneumonitis. The patients were divided into three groups according to the following indications of sirolimus use: de novo, early conversion, and late conversion groups. RESULTS The mean duration of follow-up was 11.0 ± 11.5 months. The mean blood level of sirolimus measured by microparticulate enzyme immunoassay was 16.5 ± 7.4 ng/mL at the time of diagnosis. The mean time from the start of sirolimus to pneumonitis onset was 14.7 ± 8.0 months. The clinical presentation included fever, cough, dyspnea, general weakness, and periorbital edema. In most cases, radiological imaging tests revealed bilateral lower-lobe involvement. Bronchoalveolar lavage was performed in three patients and two patients showed lymphocytic alveolitis. Sirolimus was discontinued or reduced for the treatment of pneumonitis. All cases of pneumonitis were resolved within 2 to 4 weeks. CONCLUSION Sirolimus blood level should be monitored tightly and early intervention is important when sirolimus-induced pneumonitis is suspected.

Abstract
Sirolimus is a potent immunosuppressant agent that has utility in solid-organ transplantation (SOT), particularly for its renal-sparing effects. However, lung toxicity can be a significant issue and a variety of different lung injury patterns have been described. We report an unrecognized association of sirolimus with lung cavitation in patients who have undergone cardiothoracic transplantation. Between 1996 and 2010, lung and heart transplant patients received sirolimus-based immunosuppression as a second-line agent after initial therapy with calcineurin inhibitors. All cases of sirolimus-induced lung cavities were recorded and a retrospective review of the case notes of these patients was undertaken. A total of 9 patients were identified. Clinical symptoms, time to first cavity and mean levels were variable. Some patients showed complete resolution, whereas others had persistent cavitatory lung lesions. Patients who developed persistent lung cavities had a worse outcome than those who did not have cavitation.

Abstract
Cryptogenic organizing pneumonia (COP, formerly bronchiolitis obliterans organizing pneumonia) is rare in children. We describe an 11-year-old girl with Epstein-Barr virus (EBV) reactivation/presumed post-transplant lymphoproliferative disease (PTLD) 15 months after undergoing a deceased donor kidney transplantation. Treatment with reduced immunosuppression, ganciclovir, and cytomegalovirus immunoglobulin was complicated by severe graft rejection, prompting therapy with methylprednisolone, anti-thymocyte globulin and four weekly doses of rituximab (total 1500 mg/m(2)). Tacrolimus- and prednisone-based anti-rejection prophylaxis was complemented with low-dose sirolimus. When the lactate dehydrogenase and uric acid levels rose 10 weeks after the first rituximab infusion and bilateral pulmonary nodules were detected by computerized tomography, recurrence of PTLD was suspected. Open lung biopsy of the clinically asymptomatic patient identified the nodules as COP, characterized by abundant CD3(+) T-cells, few B-cells, and the absence of EBV, cytomegalovirus, or adenovirus antigens. With normalization of the peripheral B-cell count, EB viremia reappeared and persisted, despite minimal immunosuppression. Four years later, the patient was diagnosed with classical Hodgkin lymphoma-type PTLD with multiple pulmonary and abdominal nodes. This first report of rituximab-associated, pediatric COP highlights the risk of pulmonary complications after treatment with B-cell depleting agents in solid organ transplant recipients, and the importance of a histopathologic diagnosis and vigilant follow-up of such lesions.

Abstract
Mammalian target of rapamycin (mTOR) inhibitors induce pneumonitis, an unusual but potentially fatal side effect of this drug group. We retrospectively collected the cases of pneumonitis induced by sirolimus or everolimus among 1471 adult cadaveric renal transplant recipients who were grafted at our institution from 1980-2008. Due to chronic transplant dysfunction or tumor, 205 patients were switched from calcineurin inhibitors to sirolimus (n = 88) or to everolimus (n = 117). Six patients (2.9%) developed pneumonitis: 1 was associated with sirolimus and 5 with everolimus (5 males and 1 female; median age, 60 years [range, 47-73 years]). Median times from conversion to pneumonitis onset were 34 days in 4 patients (range, 24-46 days) and 491 days in 2 subjects (range, 454-528 days). The mean drug trough level at presentation was 8.2 microg/L (range, 5.5-13.8 microg/L). The most common symptoms were dry cough (n = 6), fever (n = 5), and dyspnea (n = 4). Imaging tests revealed lower lobe involvement in all patients. Bronchoalveolar lavage performed in 4 patients showed lymphocytic alveolitis. All patients completely recovered after drug withdrawal. Five patients received steroids, 5 were switched to a calcineurin inhibitor, and 1 was switched to the other mTOR inhibitor. In conclusion, mTOR inhibitor-associated pneumonitis is a rare disease. Sirolimus did not cause more cases of pneumonitis than everolimus. Pneumonitis development was not dependent upon the drug blood level. Lower lobe involvement and lymphocytic alveolitis were usually present. Discontinuation of the mTOR inhibitor with steroid prescription resulted in adequate outcomes. A change to the other mTOR inhibitor should be contemplated if patient circumstances require this type of immunosuppression.

Abstract
PURPOSE OF REVIEW Standard immunosuppression after cardiac transplantation includes a calcineurin inhibitor in combination with mycophenolate mofetil or azathioprine and corticosteroids. These agents have led to excellent outcomes but have shortcomings in terms of efficacy and toxicity. A new class of immunosuppressants, proliferation signal inhibitors, may meet some of these shortcomings. RECENT FINDINGS The efficacy of the available proliferation signal inhibitors - sirolimus and its derivative everolimus - has been compared with azathioprine in three randomized clinical trials. Sirolimus or everolimus use was associated with lower rates of acute rejection and reduced development of chronic allograft vasculopathy. Sirolimus was not found to be superior to mycophenolate mofetil in a randomized trial. Proliferation signal inhibitors have been reported to be effective in refractory recurrent acute rejection. Nonrandomized studies have demonstrated that proliferation signal inhibitor-based immunosuppression enables recovery from renal dysfunction secondary to calcineurin inhibitor treatment. Proliferation signal inhibitor-based treatment is associated with a lower risk of malignancy than calcineurin inhibitor-based regimens. Proliferation signal inhibitors have significant adverse effects that may limit widespread use. SUMMARY Proliferation signal inhibitors are important new immunosuppressive agents that have added considerably to the armamentarium allowing further tailored immunosuppression to individualize patient care after heart transplantation.

Abstract
Sirolimus is a mammalian target of rapamycin (mTOR) inhibitor that inhibits cell cycle progression and has proven to be a potent immunosuppressive agent for use in solid organ transplant recipients. The drug was initially studied as an adjunct to ciclosporin (cyclosporine) to prevent acute rejection in kidney transplant recipients. Subsequent studies have shown efficacy when combined with a variety of other immunosuppressive agents. The most common adverse effects of sirolimus are hyperlipidaemia and myelosuppression. The drug has unique antiatherogenic and antineoplastic properties, and may promote immunological tolerance and reduce the incidence of chronic allograft nephropathy. Although sirolimus is relatively non-nephrotoxic when administered as monotherapy, it pharmacodynamically enhances the toxicity of calcineurin inhibitors. Ironically, the drug has been used to facilitate calcineurin inhibitor-free protocols designed to preserve renal function after solid organ transplantation. Whether sirolimus can be used safely over the long term with low doses of calcineurin inhibitors requires further study. The use of sirolimus as a corticosteroid-sparing agent also remains to be proven in controlled trials. Postmarketing studies have revealed a number of unforeseen adverse effects including impaired wound healing and possibly proteinuria, oedema, pneumonitis and thrombotic microangiopathy. Overall, sirolimus is a powerful agent when used judiciously with other available immunosuppressants. As is true for all immunosuppressive drugs available for treatment of solid organ transplant recipients, the efficacy of the drug must be balanced against its considerable adverse effects.

Abstract
Sirolimus-associated interstitial pneumonitis is a severe side effect of sirolimus therapy; fatal outcomes have been described. We report 4 patients with sirolimus-associated interstitial pneumonitis and review the literature for risk factors for the development of disease. Until June 2005, 48 patients received either de novo sirolimus treatment (n = 7) or were switched from a calcineurin inhibitor-containing regimen to a sirolimus-based protocol for various indications (n = 41). Compared with the 44 patients on sirolimus therapy with no evidence of a disorder, the 4 patients (8.3%) who developed suspected sirolimus-associated interstitial pneumonitis showed no difference in gender, immunosuppressive therapy, days posttransplantation, comorbidity, or preexistent lung disease. Several points, however, are of interest. None of the de novo-treated patients except 4 patients (9.8%) with late administration of sirolimus developed interstitial pneumonitis. The 4 patients with interstitial pneumonitis tended to be older (58.7 +/- 5.5 vs 46.9 +/- 1.7 years) and received higher sirolimus doses (3.5 +/- 0.5 vs 1.4 +/- 0.2 mg/d) with greater trough levels (15.4 +/- 2.9 vs 8.0 +/- 1.2 micro g/L) at the onset of symptoms. Most notably, all patients with interstitial pneumonitis had a loading dose at the start of therapy, and an increase in sirolimus dose (or trough level) within 3 weeks prior to the onset of symptoms. Additional potential risk factors identified from the literature include allograft dysfunction, hypervolemia, and male gender. With careful monitoring (or even exclusion from therapy) of patients at risk for the development of disease, we have had no case of sirolimus-associated interstitial pneumonitis since September 2004.

Abstract
Lung transplantation is now a viable therapeutic option in the care of patients with advanced pulmonary parenchymal or pulmonary vascular disease. Lung transplantation, however, with chronic posttransplant immunosuppression, creates a uniquely vulnerable population of patients likely to experience significant life-threatening complications requiring intensive care. The introduction of several novel immunosuppressive agents, such as sirolimus and mycophenolate mofetil, in conjunction with more established agents such as cyclosporine and tacrolimus, has greatly increased treatment options for lung transplant recipients and likely contributed to improved short-term transplant outcomes. Modern transplant immunosuppression, however, is associated with a host of complications such as opportunistic infections, renal failure, and thrombotic thrombocytopenic purpura. The main focus of this review is to provide a comprehensive summary of modern immunotherapy in lung transplantation and to increase awareness of the serious and potentially life-threatening complications of these medications.

Abstract
INTRODUCTION Sirolimus is a new immunosuppressive drug used in organ transplantation, particularly in renal transplantation. In the future, it could replace calcineurin inhibitors such as cyclosporine. It is currently associated with side effects, such as thrombocytopenia and hyperlipidemia. Several interstitial pneumonitis associated with sirolimus has been previously described in renal transplant recipients associated with marked general symptoms. EXEGESIS We report on a 65-year-old renal recipient presenting with a non typical case of sirolimus interstitial pneumonitis. He presented with fever and marked general symptoms for several months. CT scan showed a unilateral interstitial pneumonitis. After infectious, inflammatory and tumoral diseases were ruled out, sirolimus associated interstitial pneumonitis was evoked. The patient improved quickly after discontinuation of sirolimus. CONCLUSION It is important to evoke, after eliminating other aetiologies, sirolimus induced pneumonitis in face of an organ transplant recipient presenting with marked general symptoms even if the pulmonary symptoms are not predominant.
