Abstract
Epstein-Barr virus (EBV)-positive posttransplant lymphoproliferative disorder (PTLD) results in significant morbidity and mortality in pediatric transplant recipients. Identifying individuals at an increased risk of EBV-positive PTLD could influence clinical management of immunosuppression and other therapies, improving posttransplant outcomes. A 7-center prospective, observational clinical trial of 872 pediatric transplant recipients evaluated the presence of mutations at positions 212 and 366 of EBV latent membrane protein 1 (LMP1) as an indicator of risk of EBV-positive PTLD (clinical trials: NCT02182986). DNA was isolated from peripheral blood of EBV-positive PTLD case patients and matched controls (1:2 nested case:control), and the cytoplasmic tail of LMP1 was sequenced. Thirty-four participants reached the primary endpoint of biopsy-proven EBV-positive PTLD. DNA was sequenced from 32 PTLD case patients and 62 matched controls. Both LMP1 mutations were present in 31 of 32 PTLD cases (96.9%) and in 45 of 62 matched controls (72.6%) (P = .005; OR = 11.7; 95% confidence interval, 1.5, 92.6). The presence of both G212S and S366T carries a nearly 12-fold increased risk of development of EBV-positive PTLD. Conversely, transplant recipients without both LMP1 mutations carry a very low risk of PTLD. Analysis of mutations at positions 212 and 366 of LMP1 can be informative in stratifying patients for risk of EBV-positive PTLD.

Abstract
Post-transplant lymphoproliferative disease (PTLD) is the most common malignancy complicating solid organ transplantation (SOT) in adults and children. PTLD encompasses a spectrum of histopathologic features and organ involvement, ranging from benign lymphoproliferation and infectious-mononucleosis like presentation to invasive neoplastic processes such as classical Hodgkin lymphoma. The predominant risk factors for PTLD are Epstein-Barr virus (EBV) serostatus at the time of transplant and the intensity of immunosuppression following transplantation; with EBV-negative recipients of EBV-positive donor organs at the highest risk. In children, PTLD commonly presents in the first two years after transplant, with 80% of cases in the first year, and over 90% of cases associated with EBV-positive B-cell proliferation. Though pediatric kidney transplant recipients are at lower risk (1-3%) for PTLD compared to their other SOT counterparts, there is still a significant risk of morbidity, allograft failure, and an estimated 5-year mortality rate of up to 50%. In spite of this, there is no consensus for monitoring of at-risk patients or optimal management strategies for pediatric patients with PTLD. Here we review pathogenesis and risk factors for the development of PTLD, with current practices for prevention, diagnosis, and management of PTLD in pediatric kidney transplant recipients. We also highlight emerging concepts, current research gaps and potential future developments to improve clinical outcomes and longevity in these patients.

Abstract
BACKGROUND Epstein-Barr virus (EBV) infections can induce post-transplant lymphoproliferative disorder (PTLD). A chronic high load (CHL), as indicated by long-term high EBV DNA levels after transplantation, has been associated with an enhanced risk of PTLD. We aimed to evaluate incidence, time of occurrence, risk factors, and outcome of EBV CHL carrier state after pediatric renal transplantation. METHODS A retrospective study of 58 children aged 1-17 years (median 10), who underwent renal transplantation between January 2004 and June 2017 at a single medical center. EBV IgG antibodies in serum were analyzed before and yearly after transplantation. EBV DNA in whole blood were analyzed weekly for the first 3 months post-transplant, monthly up to 1 year and then at least once yearly. CHL was defined as EBV DNA ≥ 4.2 log10 Geq/ml in > 50% of the samples during ≥ 6 months. RESULTS At transplantation, 31 (53%) patients lacked EBV IgG and 25 (81%) of them developed primary EBV infection post-transplant. Of the 27 seropositive patients, 20 (74%) experienced reactivation of EBV. Altogether, 14 (24%) children developed CHL, starting at a median of 69 days post-transplant and lasting for a median time of 2.3 years (range 0.5-6.5), despite reduction of immunosuppression. Patients with CHL were younger and 11/14 were EBV seronegative at transplantation. No child developed PTLD during median clinical follow-up of 7.8 years (range 0.7-13). CONCLUSIONS CHL was frequent, long lasting, and occurred mainly in young transplant recipients. The absence of PTLD suggests that monitoring of EBV DNA to guide immunosuppression was effective.

Abstract
BACKGROUND Post-transplant lymphoproliferative disease (PTLD) is one of the major complications of organ transplantation, especially in children with Epstein-Barr virus (EBV) viremia (EV). We performed a retrospective study to evaluate risk factors for PTLD in children with EV. METHODS Among 199 pediatric kidney transplantation (KT) recipients at our center from January 2001 to October 2015, records of those with EBV viral loads of > 1,000 copies/mL and/or PTLD were reviewed. RESULTS Diagnosis of PTLD was made in seven patients (PTLD group), and 39 patients had EV only (EV only group). The median time from KT to EV and PTLD diagnosis was 6.7 (range 0.4-47.8) months and 8.2 (range, 2.8-98.9) months, respectively. There were no significant differences between the groups in terms of sex, age at transplantation, donor type, EBV viral load, or EV-free duration after KT. Higher tacrolimus level before EV (hazard ratio, 44.5; P = 0.003) was an independent risk factor for PTLD in multivariate Cox regression analysis. Six patients with a high EBV load (median 171,639 copies/mL) were treated with preemptive rituximab (RTX) therapy, resulting in transient reduction of EBV load. None of these patients developed PTLD (median follow-up 51.5 months); however, two had neutropenia and two developed infection requiring hospital admission. CONCLUSION In pediatric KT recipients, higher tacrolimus levels were associated with a higher incidence of PTLD. Conversely, those who received preemptive RTX for EV did not develop PTLD.

Abstract
OBJECTIVE Previous research demonstrated that salivary shedding of HSV-1 and EBV occurs often in adult renal transplant recipients, but there is a lack of studies on the presence of them in the saliva of paediatric population. Therefore, the objective of this study is to describe oral characteristics and to compare the shedding profile of HSV-1 and EBV in the saliva of children with renal transplant to that of chronic kidney disease patients and controls. METHODS This is a cross-sectional study involving 100 children, being 25 renal transplant recipients, 25 chronic kidney disease patients and 50 healthy children. Demographic and oral clinical characteristics were assessed. Saliva samples were collected and submitted to screening for EBV and HSV-1 by using nested polymerase chain reaction technique. Fisher's exact, Pearson's chi-square and Kruskal-Wallis tests were used for statistical analysis at a significance level of 5%. RESULTS Oral shedding of HSV-1 (28%) and EBV (60%) were significantly higher in renal transplant recipients compared to the other groups. Single vesicles in the oral mucosa were statistically associated with the presence of HSV-1 (p = .035). In children with chronic kidney disease, there was a higher prevalence of pale oral mucosa (32%) and enamel hypoplasia (40%) compared to paediatric renal transplant recipients and controls. Dental calculus (36%), candidiasis (8%), drug-induced gingival overgrowth (16%), mouth blisters (8%), xerostomia (12%) and salivary gland enlargement (20%) were more common in paediatric renal transplant recipients. CONCLUSIONS Therefore, it can be concluded that salivary shedding of HSV-1 and EBV in paediatric patients was more often found in renal transplant recipients than in the renal failure and control children. Transplanted recipients showed more oral manifestations than renal failure and control children did.

Abstract
The development of EBV infection and PTLD is normally associated with a high EBV viral load in peripheral blood. Observations have previously identified existence of a CHL carrier state that demonstrated variable outcomes based upon the organ which was transplanted. Data defining the incidence and outcome of CHL in pediatric KTx are not well described. The charts of children undergoing isolated KTx at Children's Hospital of Pittsburgh between January 2000 and December 2014 were retrospectively reviewed. EBV loads in the peripheral blood were routinely measured as part of surveillance protocols at our center. CHL was defined as the presence of high load for >50% of samples for ≥6 months. PTLD was defined histologically using WHO definitions. Of 188 isolated KTx recipients, we identified a total of 16 (8%) children who developed CHL carrier state. No patient developed EBV-driven late-onset PTLD. Age at the time of KTx was significantly lower in the CHL group (median 3.9 years, interquartile range: IQR 2.9-6.6, P = .0004). Children in the CHL group were more likely to be EBV-seronegative prior to KTx (94%, 15/16), compared to the UVL and LVL groups (55% and 50%, respectively, P < .002). The median duration of CHL carrier state was 20 months (IQR 10.7-35.8). Fifteen of the 16 CHL carriers experienced spontaneous resolution of CHL carrier state. Children in the CHL group were younger at the time of primary EBV infection (P = .023). Finally, antiviral medication was not effective in either preventing or decreasing the EBV viral load in blood (P = .84). Overall incidence of late-onset PTLD is very low compared to heart and intestinal transplant, even though KTx recipients can develop CHL carrier state. The CHL carriers in KTx recipients were EBV-seronegative prior to transplant and were younger both at the time of KTx and at the time of primary EBV infection compared to those in the UVL and HVL groups. Antivirals did not prevent EBV infection or decrease EBV viral loads.

Abstract
Background There is a concern that topical tacrolimus and pimecrolimus, indicated for second-line treatment of atopic dermatitis, may increase the risk of lymphoma and skin cancer, particularly in children. Objective The aim of this study was to compare incidence rates (IRs) of lymphoma and skin cancer between new users of topical tacrolimus or pimecrolimus and users of moderate- to high-potency topical corticosteroids (TCSs) and untreated subjects. Methods This is a multicenter cohort study with frequency matching by strata of propensity scores in population databases in the Netherlands, Denmark, Sweden, and the UK. IR ratios (IRRs) were estimated using Mantel–Haenszel methods for stratified analysis. Results We included 19,948 children and 66,127 adults initiating tacrolimus, 23,840 children and 37,417 adults initiating pimecrolimus, 584,121 users of TCSs, and 257,074 untreated subjects. IRs of lymphoma per 100,000 person-years were 10.4 events in children and 41.0 events in adults using tacrolimus and 3.0 events in children and 27.0 events in adults using pimecrolimus. The IRR (95% confidence interval [CI]) for lymphoma, tacrolimus versus TCSs, was 3.74 (1.00–14.06) in children and 1.27 (0.94–1.71) in adults. By lymphoma type, the highest IRR was 3.17 (0.58–17.23) for Hodgkin lymphoma in children and 1.76 (95% CI, 0.81–3.79) for cutaneous T-cell lymphoma (CTCL) in adults. For pimecrolimus versus TCSs, the highest IRR was 1.31 (95% CI, 0.33–5.14) for CTCL in adults. Compared with untreated subjects, adults using TCSs had a higher incidence of CTCL (IRR, 10.66; 95% CI, 2.60–43.75). Smaller associations were found between tacrolimus and pimecrolimus use and the risk of malignant melanoma or nonmelanoma skin cancer. Conclusion Use of topical tacrolimus and pimecrolimus was associated with an increased risk of lymphoma. The low IRs imply that even if the increased risk is causal, it represents a small excess risk for individual patients. Residual confounding by severity of atopic dermatitis, increased monitoring of severe patients, and reverse causation could have affected the results.

Abstract
Myasthenia gravis (MG), a neuromuscular junction autoimmune disease, sometimes complicates second malignancies; however, T-cell lymphoproliferative disorders have rarely been reported. A 55-year-old man, who received oral tacrolimus and prednisolone for MG for 16 years after thymectomy, presented with left abdominal pain, lymphadenopathy, and splenomegaly. A lymph node biopsy revealed peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). This is the first report of oral tacrolimus leading to a T-cell lymphoproliferative disorder in patient without a history of transplantation. Physicians should be aware of the possibility of rare T-cell lymphoproliferative disorders, such as PTCL-NOS, occurring as complications in MG patients on immunosuppressive regimens after thymectomy.

Abstract
The role of antiviral prophylaxis for the prevention of posttransplant lymphoproliferative disease (PTLD) remains controversial for solid organ transplantation (SOT) recipients who are seronegative for Epstein-Barr virus (EBV) but who received organs from seropositive donors. We performed a systematic review and meta-analysis to address this issue. Two independent assessors extracted data from studies after determining patient eligibility and completing quality assessments. Overall, 31 studies were identified and included in the quantitative synthesis. Nine studies were included in the direct comparisons (total 2366 participants), and 22 were included in the indirect analysis. There was no significant difference in the rate of EBV-associated PTLD in SOT recipients among those who received prophylaxis (acyclovir, valacyclovir, ganciclovir, valganciclovir) compared with those who did not receive prophylaxis (nine studies; risk ratio 0.95, 95% confidence interval 0.58-1.54). No significant differences were noted across all types of organ transplants, age groups, or antiviral use as prophylaxis or preemptive therapy. There was no significant heterogeneity in the effect of antiviral prophylaxis on the incidence of PTLD. In conclusion, the use of antiviral prophylaxis in high-risk EBV-naive patients has no effect on the incidence of PTLD in SOT recipients.

Abstract
Post-transplant lymphoproliferative disorders (PTLD) are a serious complication after solid organ or allogeneic hematopoietic stem cell transplantation and include a range of diseases from benign proliferations to malignant lymphomas. Risk factors for developing PTLD include Epstein-Barr virus (EBV) infection, recipient age, transplanted organ, type of immunosuppression, and genetics. Uncontrolled proliferation of EBV-infected B cells is implicated in EBV-positive PTLD, whereas the pathogenesis of EBV-negative PTLD may be similar to non-Hodgkin's lymphoma in the general population. The World Health Organization (WHO) classifies PTLD into four categories: early lesions, polymorphic PTLD, monomorphic PTLD, and classical Hodgkin's lymphoma (cHL). Treatment is aimed at cure of PTLD, while maintaining transplanted organ function. However, there are no established guidelines for the treatment of PTLD. Immune suppression reduction (ISR) is the first line of treatment in most cases, with more recent data suggesting early use of rituximab. In more aggressive forms of PTLD, upfront chemotherapy may offer a better and more durable response. Sequential therapy using rituximab followed by chemotherapy has demonstrated promising results and may establish a standard of care. Novel therapies including anti-viral agents, adoptive immunotherapy, and monoclonal antibodies targeting cytokines require further study in the prevention and treatment of PTLD.

Abstract
BACKGROUND Previous studies have found that pediatric solid organ transplant recipients suffer from adenotonsillar hyperplasia. However, as this condition is also common in normal children, it remains unclear whether the incidence is truly increased. The aim of this study was to compare the incidences of surgery on the adenoids and tonsils of normal children with those receiving renal transplants and to define risk factors in the transplant population. METHODS Data on 49 consecutive children from a single renal transplant unit were compared to data from a large governmental survey of healthy German children (KiGGS). For analysis of 'survival without operation', controls were matched for gender, region and immigration status (n = 8,650), as well as for age to compare incidence rates (n = 637). RESULTS The age-matched solid organ transplant recipients had a higher incidence of adenoidectomies [2.3-fold, [95 % confidence interval (CI) for relative risk 1.6-3.3) and a higher incidence of tonsillectomies/tonsillotomies (3.5-fold, 95 % CI 2.1-5.7). The normal peak of adenoidectomies was delayed by 2 years in the pre-school group, and transplanted teenagers showed an extra peak for both operations. Boys and those transplanted at a younger age were significantly more likely to need adenoidectomies. Ciclosporin levels, Epstein-Barr virus and cytomegalovirus infections did not influence the incidence of operations. CONCLUSION Children receiving renal transplants are at markedly increased risk of adenotonsillar hyperplasia requiring surgery, especially males and young recipients.

Abstract
A 69-year-old woman, who had been diagnosed as having Sjögren's syndrome at 37 years old and mixed connective tissue disease at 42 years old, was under treatment with oral prednisolone. In 2009, she was diagnosed as having active systemic lupus erythematosus, and started on treatment with tacrolimus at 3 mg/day. In 2010, para-aortic lymphadenopathy and superficial multiple lymphadenopathy were detected. Tacrolimus was discontinued. Axillary lymph node biopsy revealed Epstein-Barr (EB) virus-negative CD5-positive diffuse large B-cell lymphoma (DLBCL). The patient was classified into clinical stage IIIA and as being at high risk according to the international prognostic index. After the discontinuation of tacrolimus, the lymph nodes reduced temporarily in size. In January 2011, the lymphadenopathy increased again, and the patient received a total of 8 courses of therapy with rituximab, pirarubicin, vincristine, cyclophosphamide and prednisolone, followed by intrathecal injection to prevent central nervous system infiltration, which was followed by complete remission. In February 2012, fluorodeoxyglucose positron emission tomography showed relapse in multiple lymph nodes and central nervous system infiltration. The patient was considered to have iatrogenic lymphoproliferative disorder classified as "other iatrogenic immunodeficiency-associated lymphoproliferative disorders" by the WHO, and this is the first reported case of CD5-positive DLBCL and central nervous system infiltration following administration of the drug. The patient was considered to have a poor prognosis as EB virus was negative, discontinuation of tacrolimus was ineffective and there was evidence of central nervous system infiltration.

Abstract
The herpes viruses are responsible for a wide range of diseases in patients following transplant, resulting from direct viral effects and indirect effects, including tumor promotion. Effective treatments and prophylaxis exist for the neurotropic herpes viruses HSV-1, HSV-2, varicella zoster virus, and possibly HHV-6. Antivirals seem to be less effective at prevention of the tumor-promoting effects of Epstein-Barr virus and HHV-8. Reduction in immunosuppression is the cornerstone to treatment of many diseases associated with herpes virus infections.

Abstract
In this article there were regarded the most frequent side effects that appear in the patients who have been treated with topical tacrolimus, and the association between topical tacrolimus and the development of tumors is unfolded. The irritation in the site of application of the tacrolimus can manifiest as pruritus, sensation of burning and/or eritema located to the area of the application. It is the most frequent side effect, independently of the duration of the study. The cutaneous infections, especially the viral ones, tend to be more numerous in patients with atopic dermatitis that receive topic tacrolimus. After reviewing the medical literature one concludes that nowadays there doesn t exist scientific evidence of an increase of skin cancer, lymphomas or systemic immunosuppression in those patients that use or have used topical tacrolimus. Nevertheless, it is not possible to exclude the possibility that there appear cutaneous and/or systemic long-term side effects.

Abstract
BACKGROUND.: Despite the importance of non-Hodgkin lymphoma (NHL) as a posttransplant complication, the relationship between NHL and recipient seropositivity for Epstein-Barr virus (EBV) or cytomegalovirus (CMV) is incompletely understood. METHODS.: Kidney, heart, and liver transplant recipients reported to the Collaborative Transplant Study with known pretransplant EBV and CMV serostatus were analyzed in terms of clinically manifest NHL. Cox multivariate regression analysis was performed to account for a wide range of possible confounders. RESULTS.: In total, 18,682 kidney, 2042 heart, and 2616 liver transplant recipients were analyzed. Regardless of age, pretransplant EBV serostatus was significantly associated with risk of NHL in kidney transplant recipients (P<0.001). There was no significant difference in lymphoma rates according to CMV and CMV serostatus among EBV and EBV recipients (log-rank P=0.55 and P=0.57, respectively), but hospitalization for CMV disease during year 1 posttransplant was associated with subsequent NHL (hazard ratio [HR] 6.1; 95% confidence interval [CI] 2.0-18.4; P=0.001). EBV serostatus was also associated with increased risk of NHL in heart transplant patients (HR 3.6; 95% CI 1.1-11.3; P=0.031) but, contrary to expectation, not in liver recipients (HR 0.6; 95% CI 0.1-1.7; P=0.32). CONCLUSIONS.: In view of the striking increase in risk of NHL in EBV kidney transplant recipients of all ages, EBV serostatus should be determined pretransplant in all age groups. CMV serostatus was not independently associated with risk of NHL after kidney transplantation. Surprisingly, in liver transplantation, the risk of NHL was virtually unaffected by EBV serostatus.

Abstract
Antiviral prophylaxis with valganciclovir is used frequently in pediatric solid organ transplant patients to prevent Epstein-Barr virus (EBV)-induced infections and tissue-invasive disease including post-transplant lymphoproliferative disorder (PTLD). This approach is untested in clinical trials and valganciclovir dosing strategies in children are highly variable. Our objective was to characterize the pharmacokinetics of ganciclovir in the plasma of pediatric kidney and liver transplant patients taking valganciclovir for EBV prophylaxis. Virologic response was also evaluated. Ganciclovir was measured by liquid chromatography/ultraviolet detection. EBV DNA was quantified by TaqMan(®) polymerase chain reaction. NONMEM(®) VI was used for data analysis. Ganciclovir plasma profiles were consistent with a one-compartment model. Final model estimates of apparent oral clearance (L/h), apparent volume of distribution (L), and absorption rate constant were 7.33, 35.1, and 0.85, respectively. There was evidence of lower bioavailability in children younger than three years. All eight subjects achieved ganciclovir plasma concentrations above reported in vitro concentrations needed to inhibit EBV replication by 50%. However, four subjects had detectable EBV DNA with a median (range) of 18,300 (4,400 to 54,900) copies/mL of whole blood. These findings support the need for further studies of the clinical pharmacology and efficacy of valganciclovir for EBV prophylaxis.

Abstract
BACKGROUND Atopic dermatitis (AD) is a chronic disease characterized by periods of remission and relapse. Therapeutic objectives for AD should be to quickly reduce disease symptoms by targeting pathophysiological pathways, and to provide long-term management by reducing recurrences. OBJECTIVE Calcineurin inhibitors currently appear to be one of the most promising alternative systemic and topical compounds to treat AD. This review focuses on new developments of topical calcineurin inhibitors, therapeutic regimens including long-term management, and prophylaxis of AD. METHODS The published clinical studies that present data on treatment of AD with calcineurin inhibitors were assessed. RESULTS/CONCLUSION Topical calcineurin inhibitors such as tacrolimus and pimecrolimus provide an effective treatment for AD. They are useful for long-term management and prophylaxis of AD. Safety concerns with regard to increased risk for lymphomas or skin cancer could not be confirmed but will remain under careful observation.

Abstract
Pediatric renal transplant recipients were enrolled in a multicenter, randomized, double-blind trial of steroid withdrawal. Subjects received basiliximab, calcineurin inhibitor, sirolimus and steroids. Of 274 subjects enrolled, 19 (6.9%) subjects developed posttransplant lymphoproliferative disorder (PTLD). The relative hazard (RH) for PTLD was 5.3-fold higher in children aged < or =5 versus those >12 years (p = 0.0017). EBV seronegative subjects had a 4.7-fold higher RH compared to EBV positive subjects (p = 0.02). Among EBV donor+/recipient- (D+/R-) subjects, the RH increased by 6.1-fold (p = 0.0001). In a multivariate model, risk factors included recipient age < or =5 years (RH 3.2, 95% CI: 1.1-9.6, p = 0.034) and EBV D+/R- status (RH 7.7, 95% CI: 1.6-35.9, p = 0.010). Of 19 patients with PTLD, 17 are alive with functioning grafts and 2 lost their grafts, 1 of whom subsequently died of recurrent PTLD. This 'robust' immunosuppression protocol was associated with low rejection rates but an unacceptably high incidence of PTLD. The combination of basiliximab, calcineurin inhibitor, sirolimus and steroids resulted in over-immunosuppression in a high-risk pediatric population and we do not recommend its use. Future studies must include routine viral monitoring to permit early identification of viral activity and a protocol driven reduction of immunosuppression aimed at avoiding complications.

Abstract
EBV infection is one of major complications arising in pediatric patients who have undergone renal transplantation. A strong correlation between the grade of immunosuppression and the development of PTLD, one of the most severe EBV-associated diseases, has been recognized. In this study, we monitored the serologic profile in conjunction with peripheral blood EBV-DNA load of 32 children who underwent renal transplantation with tacrolimus as an immunosuppressant. Six patients were EBV-seronegative (EBV-) before the transplantation, and the mean DNA load in the EBV- group was significantly higher than that in the EBV-seropositive (EBV+) group. Seroconversion occurred in five of these patients in a mean period of 22 weeks after the transplantation. The EBV-DNA load in the EBV+ group was maintained at a low level for a year, whereas it increased rapidly to over 1 x 10(5) copies/mL in two patients in the EBV- group three to seven months after the transplantation, which corresponds to the timing of seroconversion, and one of them developed PTLD. These observations suggest that the close monitoring of the EBV-DNA load, along with longitudinal observation of seroconversion, is essential in pediatric renal transplantation, particularly for younger children who are more likely to be EVB-.

Abstract
BACKGROUND Primary Epstein-Barr virus (EBV) infection is the most important risk factor for development of posttransplant lymphoproliferative disorder (PTLD). Pediatric patients are often EBV seronegative pretransplant placing them at high risk. In the immune-competent population, primary herpesvirus infection is associated with higher morbidity with increasing age. METHODS We performed a retrospective cohort study to describe the outcome of pediatric renal transplant recipients with primary EBV infection. All patients received 3 months of ganciclovir prophylaxis. Real-time quantitative polymerase chain reaction was used to determine the EBV viral load. Primary EBV infection was categorized as PTLD, symptomatic infection, or subclinical infection. RESULTS There were a total of 46 patients with primary EBV infection: 11 developed PTLD, 12 had symptomatic infection, and 23 had subclinical infection. Adolescents were significantly more likely to develop PTLD than younger transplant recipients (P=0.05, chi-square). Multivariate analysis using logistic regression found that older age was the only significant risk factor for PTLD (odds ratio 1.24, 95% confidence interval 1.04-1.47; P=0.03). Among the 11 cases of PTLD, there were two deaths and two graft failures which all occurred in adolescent recipients (P=0.002). CONCLUSIONS Among pediatric renal transplant recipients with primary EBV infection, adolescents are at significantly higher risk to develop PTLD and have poorer outcomes compared to younger recipients.

Abstract
PURPOSE OF REVIEW The classic role of topical and systemic corticosteroids for allergic dermatoses is discussed, with special attention to the impact on the current clinical treatment paradigm by newer systemic and topical therapies. These products are reviewed and recommendations presented on how to effectively assimilate them into clinical practice. RECENT FINDINGS Current knowledge about the etiopathogenesis of atopic dermatitis has resulted in drug development focused on agents with less toxicity than current topical and systemic corticosteroids. Some agents with ceramide/cholesterol/acid combinations demonstrate efficacy in restoring the dysfunctional skin barrier of atopic patients. Concerns resulting from the recent Federal Drug Administration announcement regarding a theoretical risk of cancer associated with topical calcineurin inhibitors are also addressed. Novel therapeutic entities are presented. SUMMARY Patients seeking relief from atopic dermatitis have historically had few really effective and safe therapeutic options. Topical calcineurin inhibitors represent an exciting new therapy for atopic dermatitis without the side-effect profile associated with topical corticosteroids. Nonsteroidal formulations incorporating glycyrrhetinic acid/telmesteine/Vitis vinifera extract and palmitoylethanolamide as 'active' ingredients recently entered the market, stressing antipruritic, antiinflammatory, and skin barrier repair. This confabulates against previously designed topical therapy paradigms. These new products may be used as monotherapy or alternatives to steroid agents.

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
PURPOSE OF REVIEW Heart transplantation has become a reasonable treatment option for pediatric patients with end-stage heart failure or complex congenital cardiac defects not amenable to conventional surgical intervention. This review will summarize the current state of pediatric cardiac transplantation and review recent advances leading to new therapies. RECENT FINDINGS Improvements in early mortality after cardiac transplantation have occurred consistently over time since the 1980s, short-term survival rates are high, and most patients enjoy an excellent quality of life with minimal restrictions. The reduction of late mortality is still a major challenge, however, largely as a result of transplant-related coronary artery disease causing chronic graft failure and arrhythmogenic sudden death. Additional causes of morbidity and mortality occurring late after transplantation include renal dysfunction related to chronic immunosuppressive therapy with calcineurin inhibitors (tacrolimus or cyclosporine) and posttransplant lymphoproliferative disorders related to chronic immunosuppression. Newer agents (sirolimus, everolimus) have shown promise in immunosuppressive regimens that may alter the development or progression of long-term complications. SUMMARY New immunosuppressive agents allow alterations in drug regimens to minimize renal complications, and may influence the incidence and progression of transplant vasculopathy. Recent studies on posttransplant lymphoproliferative disorders should result in earlier diagnosis and therapy.

Abstract
Posttransplant lymphoproliferative disorder (PTLD) is a serious complication of organ transplantation, with a reported incidence between 0.8% and 32%. The incidence of PTLD mainly depends on the transplanted organ, the immunosuppressive drugs, the viral serology, and the age of the recipient. The aim of our study was to analyze our patients diagnosed with PTLD. Among 1040 transplantations, including 931 renal, 14 heart, 55 liver and 40 allogeneic peripheral blood stem cell (PBSC), 8 patients (7 male, 1 female) were diagnosed with PTLD. Five patients had undergone renal, one cardiac, one liver, and one PBSC transplantations. Four patients were diagnosed within the first year of transplantation. Six patients presented with abdominal disease, one with convulsions, and one with peripheral lymph node involvement. According to the World Health Organization classification system, six patients were diagnosed as diffuse large B-cell lymphoma, one patient Burkitt's lymphoma, and one polymorphic PTLD. At the time of diagnosis, 7 patients showed positive Epstein-Barr virus (EBV) and cytomegalovirus (CMV) Ig G and negative Ig M; one patient, positive EBV Ig M and negative CMV Ig G and M. EBV viral load was extremely high in the plasma of two patients by polymerase chain reaction. One of these patient's pathologic tissue revealed positive EBV DNA, which was not detected in six of the other eight patients. This patient was an 8-year-old boy diagnosed with Burkitt's lymphoma at 31 months after liver transplantation. Seven patients died of disease or complications of chemotherapy. Only one patient survived after the diagnosis of PTLD. In conclusion, even with treatment the mortality rate was high among our patients with PTLD. To decrease the incidence of PTLD and related mortality, risk factors must be evaluated in multicenter studies.

Abstract
Immunosuppression after heart transplantation is implicated in development of post-transplant lymphoproliferative disorder (PTLD). Despite a higher prevalence of PTLD in children, there is scarce knowledge about incidence, pathophysiologic mechanisms and risk factors for PTLD in pediatric recipients of cardiac allografts. We examined retrospectively the medical records of all 143 pediatric patients (mean age 9.2 +/- 6.1 yr) who received donor allografts between 1984 and 2002 and survived over 30 days. Five children (3.5%) developed PTLD over a mean follow-up period of 41.1 +/- 46.0 months. Time from transplant to diagnosis of PTLD ranged from 3.9 to 112 months (mean 48.0 +/- 41.9 months). Excluding PTLD, no other malignancies were found in this population. Actuarial freedom from PTLD was 99.2%, 99.2% and 96.2% at 1, 2, and 5 yr, respectively. Children who developed PTLD were more likely (by univariate analysis) to have been Rh negative (p = 0.01), Rh mismatched (p = 0.003), Epstein-Barr virus (EBV) seronegative (p = 0.001) and transplanted for congenital heart disease (p < 0.02). PTLD was associated with significant morbidity and mortality with a mean survival following diagnosis of 21.2 months. PTLD is a serious complicating outcome of cardiac transplantation that occurs in approximately 3.5% of children. Aside of immunosuppression, risk factors in this series for developing PTLD include EBV seronegativity and Rh negative status and mismatch. Non-hematogenous malignancies are rare in light of short allograft half-life.

Abstract
Pediatric and adult kidney transplantation differ in many ways, but one of the most significant differences is the impact of kidney disease and kidney transplantation on growth and development in pediatric patients. Multiple facets of transplantation may have an impact on growth and development, including the timing of transplantation, choice of immunosuppressive agents, and the presence of hypertension. In addition, graft function has a significant impact on linear growth, and so preservation of function becomes important not only for general health and quality of life but also for optimizing growth. Other concerns in pediatric kidney transplantation include a heightened risk for posttransplantation infectious complications, including lymphoproliferative disease. In addition, the impact of immunosuppressive drugs on adherence to therapy is important. Although adherence is a complex and multifactorial process, immunosuppressive drugs that cause physical side effects may contribute to drug nonadherence because children, and particularly adolescents, may be inclined to stop taking medications associated with physical changes that differentiate them from their peers. Studies that further delineate factors that affect growth and development, risk for infectious complications, and nonadherence will be important to maximize outcomes in pediatric kidney transplantation.

Abstract
The development of Epstein-Barr virus (EBV) associated lymphoproliferative disorder (PTLD) is related to EBV genome numbers in serum or plasma and B-cells, and the level of immunosuppression. EBV DNA viremia, defined as presence of EBV genomes in serum or plasma, is common in immunodeficiency. This survey of EBV viremia was performed by real-time polymerase chain reaction (PCR) on consecutive serum samples of 21 patients with acute (n = 3) or chronic liver disease (n = 18) during the first year after liver transplantation (LTX). Cytomegalovirus (CMV) DNA was analyzed with PCR in serum or leukocytes. The levels of EBV and CMV viremia were related to PTLD and the effect of different anti-rejection regimens. All patients were EBV-seropositive pre-LTX. In total, 24 of 152 (16%) samples from 10 of 21 (48%) individuals were EBV positive [five of 11 cyclosporin A (CsA); five of 10 tacrolimus treated cases]. EBV viremia was demonstrated in five of seven patients with OKT3 therapy. The number of EBV DNA positive samples was highest (26%) at 14 days after LTX. In the OKT3 treated groups, the medians of EBV DNA copy numbers were 1600/ml (range 230-7200) and 380/ml (range 120-860) in the CsA and tacrolimus patients, respectively (P < 0.02). One patient developed EBV lymphoma and another one EBV hepatitis 13 months and 24 days post-LTX, respectively. Both patients had received OKT3. Their EBV genome load was not significantly different from what was found in other patients. After ganciclovir therapy, EBV DNA was eradicated from serum in four of five patients for several months. EBV DNA load was not affected by CMV infection or disease. We conclude that presence of EBV in serum is a possible marker of an active infection and an early ganciclovir therapy may be beneficial. Quantification of EBV load offers the potential to implement pre-emptive interventions.

Abstract
Viral pathogens have emerged as the most important microbial agents having deleterious effects on solid organ transplant (SOT) recipients. Antiviral chemoprophylaxis involves the administration of medications to abort transmission of, avoid reactivation of, or prevent progression to disease from, active viral infection. Cytomegalovirus (CMV) is the major microbial pathogen having a negative effect on SOT recipients. CMV causes infectious disease syndromes, augments iatrogenic immunosuppression and is commonly associated with opportunistic superinfection. CMV has also been implicated in the pathogenesis of rejection. Chemoprophylactic regimens for CMV have included oral aciclovir (acyclovir) at medium and high doses, intravenous and oral ganciclovir, and the prodrugs valaciclovir (valacyclovir) and valganciclovir. CMV prophylactic strategies should be stratified, with the highest-risk patients receiving the most 'potent' prophylactic regimens. Herpes simplex virus (HSV) reactivation in SOT recipients is more frequent, may become more invasive, takes longer to heal, and has greater potential for dissemination to visceral organs than it does in the immunocompetent host. Prophylactic regimens for CMV are also effective chemoprophylaxis against HSV; in the absence of CMV prophylaxis, aciclovir, valaciclovir or famciclovir should be used as HSV prophylaxis in seropositive recipients. Primary varicella-zoster virus (VZV) after SOT is rare and most commonly seen in the paediatric transplant population because of VZV epidemiology. Zoster occurs in 5-15% of patients, usually after the sixth post-transplant month. Prophylactic regimens for zoster are neither practical nor cost effective after SOT because of the late onset of disease and low proportion of affected individuals. All SOT recipients should receive VZV immune globulin after contact with either varicella or zoster. Epstein-Barr virus has its most significant effect in SOT as the precipitating factor in the development of post-transplant lymphoproliferative disorders. Antiviral agents that could be effective are the same as those used for CMV, but indications for and effectiveness of prophylaxis are poorly established. Hepatitis B virus (HBV) and hepatitis C virus (HCV) are important pathogens in the SOT population as indications for transplantation. So-called 'prophylaxis' for recurrent HBV and HCV after liver transplantation is controversial, suppressive rather than preventive, and potentially lifelong. Influenza infection after SOT is acquired by person-to-person contact. During epidemic periods of influenza, transplant populations experience a relatively high frequency of infection, and influenza may affect immunosuppressed SOT recipients more adversely than immunocompetent individuals. Antiviral medications for prevention of influenza are administered as post-exposure prophylaxis to SOT recipients, in addition to yearly vaccine, in circumstances such as influenza epidemics and nosocomial outbreaks, and after exposure to a symptomatic individual during 'flu season'.

Abstract
The Epstein-Barr virus (EBV)-induced post-transplant lymphoproliferative disorder (PTLD) affects 1%-10% of all paediatric renal transplant recipients. This is a heterogeneous group of conditions characterised by EBV-driven proliferation of B-lymphocytes in the face of impaired T-cell immune surveillance. The risk factors predisposing to PTLD are becoming better understood, but its pathogenesis and myriad of clinical and histological features remain poorly defined. While new treatment modalities are being tried with variable success, regular EBV surveillance and carefully monitored reduction of immunosuppression remain the mainstay of treatment. In this review, we have presented the current knowledge of this increasingly common complication in renal transplant recipients.

Abstract
BACKGROUND Lymphoproliferative disease (PTLD) is a life-threatening complication of organ transplantation. In matched, allogeneic, non-T-cell-depleted stem-cell transplantations (SCT) the disease develops early but has been thought to be rare. OBJECTIVES We determined by strict histopathological criteria the incidence of fatal Epstein-Barr-virus (EBV)-related PTLD in a large number of SCT, and assessed the diagnostic value of a real-time quantitative polymerase chain reaction (qPCR) for EBV-DNA in serum specimens. STUDY DESIGN Of the 257 SCT performed in Helsinki during 1994-1999, 132 (51%) recipients were alive and 125 (49%) had succumbed by June 2001. The necropsies were analyzed for EBV-related PTLD as evidenced by disseminated lymphocytic infiltrates labeled histochemically for antigens and RNA (EBER 1 and 2) detectable by in situ technology. From a subset of the PTLD cases (N=12) and a series of corresponding stem-cell recipient controls (N=36), consecutive samples of serum (N=103 and 364, respectively) were studied by qPCR for EBV-DNA, and the clinical data were reviewed. RESULTS The post-mortem analysis revealed 18 cases of PTLD (14% of the deceased), all of whom had received intensive immunosuppressive treatment including anti-thymocyte globulin for treatment or prophylaxis of graft versus host disease (GVHD). By using qPCR all the PTLD patients became EBV-DNA positive, in progressively rising copy numbers. EBV-DNA was first detectable 70 (median; range 24-154) days after SCT or 23 (4-86) days before death; i.e. earlier than the symptoms which appeared 15 (2-85) days before death. Among the SCT controls, EBV-DNA occurred sporadically (in only 3.9% sera). CONCLUSIONS qPCR for EBV-DNA in serum is a highly sensitive (100%) and specific (96%) diagnostic approach. Intensely immunosuppressed stem-cell recipients are at a great risk of developing PTLD, and should be carefully monitored for EBV-DNA, for pre-emptive treatment of this life-threatening disorder.

Abstract
Pediatric transplantation has seen remarkable advances over the past two decades with reduced morbidity and mortality, reduced rejection rates, and improved long-term patient and allograft survival. Infants currently have short-term patient and allograft survival rates better than any other age group; short-term allograft survival rates in CD recipients are equal to those in LD recipients. With decreased rejection, long-term allograft survival is improving dramatically. Transplantation allows for much reduced risks and improved metabolic status, growth and development, and more normal social interactions. The future of transplantation continues to be exciting, with opportunities for reduced immunosuppressive medications and their side effects, and the elusive goal of transplantation tolerance seems within reach.

Abstract
Increased understanding of the mechanisms by which T lymphocytes recognize virus and tumor-specific antigens has fueled the use of adoptive immunotherapy for viral and malignant diseases. An ideal candidate for such treatment is Epstein-Barr virus (EBV). EBV-associated post-transplant lymphoproliferative disorder (PTLD) is a serious complication post-solid organ transplant (SOT) or hematopoietic stem cell transplant (HSCT). The disease is essentially the result of suppression of cytotoxic T-cell function and despite various treatment strategies the course may still be fulminant and lethal. Therefore, an adoptive immunotherapeutic approach using ex vivo derived EBV-specific CTL offers a promising solution not only for the treatment but also as prophylaxis for PTLD. The infusion of EBV-CTL has been demonstrated to be safe and effective in allogeneic HSCT recipients and their use post-SOT is being evaluated.

Abstract
Epstein-Barr virus (EBV) is associated with the development of lymphoproliferative disorders in the immunocompromised host and in particular post-transplant recipients. The development of a rapid real-time quantitative PCR for the detection of the immediate early gene BZLF1 is described using the Roche LightCycler. BZLF1 codes for the ZEBRA protein, one of the cascade of transactivation factors involved in the lytic life cycle of the virus. The assay is rapid and can detect a single copy of EBV DNA. Intra- and inter-assay variability studies using the external quantitative standards and DNA extracted from whole blood and plasma samples were shown to be within a 0.5 log(10) range.

Abstract
BACKGROUND Posttransplant lymphoproliferative disorder (PTLD) remains a difficult management issue; therefore, many studies focus on the identification of risk factors to allow for preventive strategies. We investigated risk factors for PTLD in the adult renal transplant setting. METHODS A single-center, matched case-control study design was used. Cases were identified from patients who underwent a first renal transplant between January 1, 1985, and December 1, 2001. Two controls were chosen per case, matched (+/-1 year) by date of transplant and graft survival. Clinical and demographic data were ascertained from medical records. Pretransplant serology for Epstein-Barr virus (EBV) and cytomegalovirus was confirmed on frozen, stored sera. Statistical analysis included univariate and multivariable examination of putative risk factors using conditional logistic regression. RESULTS Twenty cases of PTLD were identified, an incidence of 2.4%. Median time from transplant to diagnosis was 55 months (range, 3-168 months), with 16 cases of late-onset PTLD (>1 year posttransplant). The only significant risk in univariate analysis was EBV-negative status at transplant (risk ratio 6.0, P=0.03). In multivariable analysis, EBV-negative status remained significant (adjusted risk ratio 8.9, P=0.01). The risk related to EBV status held true when late cases were analyzed separately (adjusted risk ratio 7.1, P=0.03). CONCLUSIONS Pretransplant EBV-seronegative status is a strong risk for development of PTLD in adult renal allograft recipients, even in late disease. These results indicate that primary infection with EBV may have a pathogenic role in some cases of late PTLD.

Abstract
PURPOSE OF REVIEW With the improved long-term outcome of renal allograft recipients, malignant tumours or cardiovascular disease become increasingly important. Malignant tumours develop in 15-20% of graft recipients after 10 years, and thus contribute substantially to the morbidity and mortality of these patients. In contrast to the general population, skin tumours and lymphoproliferative disorders are the most frequent malignancies in transplant recipients. Malignancies can develop in three ways: de-novo occurrence in the recipient; recurrent malignancy in the recipient; or transmission of malignancy from the donor. RECENT FINDINGS The immunosuppressive strategies after renal transplantation differ with respect to the development of malignancies, with cell-depleting antibodies being the highest risk, whereas newer immunosuppressants such as rapamycin could possess anti-tumour potential. The relationship of chronic viral infections to skin tumours and lymphoproliferative diseases has become clearer during recent years. Concomitantly, experience in the management of such diseases has grown. Furthermore, as older donors are accepted, awareness of the possibility of transferring malignancies from the donor to the recipient must increase. SUMMARY Malignancies are a major contributor to morbidity and mortality among kidney transplant recipients as such diseases gain importance with longer graft survival. Immunosuppression and chronic viral infections in combination with the transmission of malignant cells from the donor or recurrent malignancies contribute to the increased incidence of cancer. In kidney transplant recipients, screening before and after transplantation and an individualized choice of immunosuppression are thus mandatory.

Abstract
UNLABELLED We report the case of a 12-year-old boy, who developed Epstein-Barr virus (EBV) associated post-transplant lymphoproliferative disease (PTLD) 7 years after renal transplantation. He responded well to the reduced immunosuppressive therapy and treatment with ganciclovir. Two years later he developed severe pneumonia and hypogammaglobulinaemia related to EBV infection exacerbation. An X-ray film revealed persistent pneumonia in the right lung. Lung biopsy showed a large, diffuse EBV-associated B-cell lymphoma. This constellation suggested re-occurrence of the primary PTLD. CONCLUSION We present a case of recurring Epstein-Barr virus-associated post-transplant lymphoproliferative disease with a remarkably late onset in addition to hypogammaglobulinaemia.

Abstract
We tested blood samples of 25 pediatric renal transplant recipients for Epstein-Barr virus (EBV) DNA load by quantitative polymerase chain reaction (PCR). Eleven of these transplant recipients showed clinical persistent mononucleosis-like symptoms years after transplantation (Tx). A quantitation of EBV DNA by PCR in peripheral blood lymphocyte (PBL) and serum samples revealed variable EBV DNA titers. The majority of EBV PCR results in samples of the 14 asymptomatic transplant recipients was repeatedly below detection limit. In contrast, patients with mononucleosis-like symptoms showed persistent EBV genome titers over a period of 6 months, ranging from 75 to 18 750 copies/10 000 PBL and from 680 to 335 000 copies/mL serum, respectively. One child suffering from this mononucleosis-like condition developed an EBV-associated Burkitt-like lymphoma 29 months after Tx. Whereas clinical and histological investigations did not indicate a post-transplant lymphoproliferative disorder (PTLD) until tumor detection, EBV titers in PBL and serum had been high for at least 8 months. We propose that pediatric transplant recipients who show both, recurrent mononucleosis-like symptoms and a sustained high EBV genome load, are at increased risk for severe EBV-related post-transplant complications.

Abstract
BACKGROUND Infections caused by herpes virus, in particular, Epstein-Barr virus (EBV), remain a major challenge in solid organ transplantation. Little is known about the significance of tissue EBV load. METHODS Twenty-three tissue biopsy specimens (19 kidney, 3 gastrointestinal, and 1 tonsil specimen) and 2 bronchoalveolar lavage specimens from 14 pediatric transplant recipients (10 kidney, 3 liver, 1 combined transplant) were subject to tissue EBV polymerase chain reaction (PCR) semiquantitative analysis and enzyme-linked immunosorbent assay (ELISA) methods. Results of biopsies were correlated with clinical data. RESULTS Five of 14 patients had clinically diagnosed EBV disease: 2 patients presented with a septic picture with multiorgan failure and pneumonitis; 1 patient had mononucleosis; 1 patient had an increase in serum creatinine level, lymphadenopathy, and chronic fatigue; and 1 patient had EBV nephritis. These 5 patients underwent 12 biopsies at the time of clinically active infection; 8 biopsies had positive results (up to 111 copies/10 microL of extracted DNA). Conversely, 1 of the remaining 13 tissue biopsy specimens from asymptomatic patients had positive results on ELISA, but undetectable viral load, whereas 8 patients had a positive EBV immunoglobulin G titer with historic evidence of EBV replication in the blood. No patient without evidence of EBV had positive EBV tissue PCR results. CONCLUSION Increased EBV load was found in more than 50% of patients, pointing to a previously underrecognized importance of EBV detection in tissues from transplant recipients. The presence of EBV in tissue correlated with the presence of viremia, whereas tissue PCR had 100% specificity. EBV load should be included in biopsy evaluation.

Abstract
Lymphomas are a well-known malignancy in individuals with human immunodeficiency virus type 1 (HIV-1) infection. Most lymphomas are of B-cell lineage and cutaneous involvement is rare. Cutaneous T-cell lymphomas have been previously described in adults with HIV-1 infection but are exceptional in HIV-1 infected-children. The authors report here the extremely rare case of a large-cell cutaneous lymphoproliferation of T-cell lineage expressing Epstein-Barr virus (EBV) antigens in a 15-year-old boy with AIDS and his uncommon clinical presentation. The atypical clinical evolution with a nonaggressive treatment emphasizes that for immunosuppressed patients, the diagnosis of immunosuppression-related lymphoproliferative disorder should be considered before giving the diagnosis of malignant lymphoma when tumoral lymphoid cells express EBV antigens.
