Background: Streptococcus pneumoniae (S. pneumoniae) and Hemophilus influenzae (H. influenzae) are among the main vaccine-preventable bacterial infections in immunocompromised individuals including solid organ transplant (SOT) recipients. There is a lack of information about incidence and outcomes of these infections in SOT recipients. Methods: We determined the incidence of S. pneumoniae and H. influenzae, the related hospitalization, and 30- and 180-days mortality in a large cohort of 1182 adult SOT recipients. We calculated 95% confidence intervals (CI) of incidence rate (IR) using Byar’s approximation to the Poisson distribution. Results: The overall IR of S. pneumoniae and H. influenzae were 1086 (95% CI, 796–1448) and 1293 (95% CI, 974–1687) per 100,000 person-years of follow-up (PYFU), respectively. The IR of invasive infections were 76 (95% CI, 21–202) and 25 (95% CI, 2.3–118) per 100,000 PYFU, respectively. Hospital admission was required in >50%, 30-days mortality was 0, and 180-days mortality was 8.8% and 4.5% after S. pneumoniae and H. influenzae infections, respectively. Conclusions: The IR of invasive S. pneumoniae and H. influenzae infections in SOT recipients were much higher than reports from the general population in Denmark. Furthermore, a large proportion of infected SOT recipients were hospitalized. These findings highlight the need for further studies to assess uptake and immunogenicity of vaccines against S. pneumoniae and H. influenzae in SOT recipients.

Introduction: Depression and anxiety are common affective experiences during the first year following a solid organ transplant. This study examined the degree to which an evidenced-based clinical intervention implemented by social workers—Symptom Targeted Intervention—can alter self-reported depression and anxiety in heart, kidney, liver, and lung transplant recipients. Research Questions: This investigation explored 2 questions: (1) Can symptom-targeted interventions significantly reduce posttransplant recipients’ self-reported depression and anxiety at the conclusion of treatment and at 1-month follow-up? and (2) Does the response differ by gender? Design: A 1-group pretest–posttest design with a 1-month follow-up was used to test for changes in anxiety and depression after transplantation. Forty-eight patients at 2 US transplant centers were enrolled between January 2016 and May 2017. Data were collected using an online platform and analyzed to assess for differences over time and by gender. Results: Anxiety decreased significantly between pretest and posttest using the General Anxiety Disorder-2 ( P < .05). Comparisons by gender indicated that women had a significant decrease in anxiety between pretest and posttest ( P < .001); however, there was no significant decrease in anxiety for men. Analyses by gender and time yielded no significant differences for depression. Discussion: Symptom-targeted interventions have the potential to reduce anxiety in solid organ transplant patients and enhance their psychosocial adjustment after surgery.

Abstract Background: Post-transplant lymphoproliferative disease (PTLD) confers a high morbidity and mortality in a vulnerable population. We present the epidemiology and outcomes of PTLD in a large UK cohort of solid organ transplant (SOT) recipients who were transplanted over a 20-year period. Methods: This is a retrospective study of 5365 SOT recipients who had their first transplant between 2000 and 2021 at two UK transplant centres (Addenbrooke's Hospital and Papworth Hospital). We reviewed the records of all patients and found 142 who subsequently developed PTLD. For each type of transplant, we calculated the incidence rate of PTLD and cumulative incidence using a competing risk of death model. Survival was compared with the age-adjusted life expectancy of the UK population using the National life tables and a landmark analysis was performed to compare overall survival (OS) of PTLD patients from the date of diagnosis with the background survival of the transplant population. To compare treatment outcomes, a subset of 90 cases of monomorphic PTLD, DLBCL subtype were identified. 66 were treated with first-line Rituximab monotherapy and 24 received first-line R-Chemotherapy. Demographics, treatment response, and survival data were analysed with univariate and multivariate analysis to identify covariates associated with death in the first year post diagnosis of PTLD. Results: With a median follow-up time of 5.3 years, 142 of 5365 solid organ transplant recipients have developed PTLD (56/1965 kidney, 22/1428 liver, 12/327 simultaneous kidney-pancreas (SPK), 21/113 multivisceral (MVT), 10/778 heart, 15/503 bilateral lung, 3/148 single lung and 3/85 heart and lung). The incidence rate of PTLD was highest in the first year post-transplant in lung and MVT recipients. Cumulative incidence (shown in Figure 1) was 18% at 5 years post-MVT and 1-3% at 5 years following the other SOT types. Cumulative incidence was lowest for liver and heart transplants and was 10% at 20 years post-kidney transplantation. Median OS following SOT was 16 years which is significantly reduced compared with the age-adjusted UK population. There is a relatively high early mortality rate following diagnosis of PTLD and only patients surviving two years post diagnosis regained a similar longer-term survival to the non-PTLD SOT cohort. Treatment with rituximab monotherapy (RM) is now a standard of care for monomorphic PTLD 1. Outcomes for monomorphic patients were compared between those treated with RM (n=66, median follow-up 2.2 y) and R-Chemotherapy (n=24, median follow-up 5.2 y). The two groups were well matched for age and IPI. Of the 66 RM patients, 22 (33%) achieved complete remission with RM and required no further treatment. A further 18 (27%) patients achieved remission following further treatment with chemotherapy/surgery/CTL. 6/66 (9%) patients died of progressive disease (PD), 9/66 (14%) died pre-remission of non-PTLD causes and 11/66 (17%) died in remission of unrelated causes. In the R-Chemotherapy group, 22 patients received R-CHOP and 2 received R-CVP (n=24). 8 (33%) patients are alive and in remission after first line treatment and a further 3 patients (13%) after second line treatment. 2/24 (8%) patients died of PD, 4/24 (17%) died pre-remission of non-PTLD causes and 7/24 (30%) died post-remission of unrelated causes. There is no significant difference in OS between the two groups. Only a minority of deaths were due to PD and death from non-lymphoma causes pre and post remission remain considerably higher than non-PTLD SOT patients up to 2 years post treatment (Figure 1). Multivariate analysis of all 90 monomorphic PTLD patients identified IPI3+ as the strongest pre-treatment variable associating with inferior 1 year OS. Interestingly IPI3+ did not retain this significance when R-chemo patients were analysed alone. Conclusion: With this large SOT dataset we have mapped the cumulative incidence of PTLD over a 20 year period and highlight transplanted organ-specific differences in PTLD incidence over time. Treating monomorphic DLBL patients first-line with RM rather than R-chemotherapy does not appear to compromise OS, but the number of patients dying from non-lymphoma causes pre- and post-treatment remains high with both treatment approaches, with poor OS compared with age-matched non-PTLD SOT recipients. 1Trappe et al.

Abstract Background The coronavirus disease 2019 (COVID-19) pandemic has led to significant reductions in transplantation, motivated in part by concerns of disproportionately more severe disease among solid organ transplant (SOT) recipients. However, clinical features, outcomes, and predictors of mortality in SOT recipients are not well described. Methods We performed a multicenter cohort study of SOT recipients with laboratory-confirmed COVID-19. Data were collected using standardized intake and 28-day follow-up electronic case report forms. Multivariable logistic regression was used to identify risk factors for the primary endpoint, 28-day mortality, among hospitalized patients. Results Four hundred eighty-two SOT recipients from &gt;50 transplant centers were included: 318 (66%) kidney or kidney/pancreas, 73 (15.1%) liver, 57 (11.8%) heart, and 30 (6.2%) lung. Median age was 58 (interquartile range [IQR] 46–57), median time post-transplant was 5 years (IQR 2–10), 61% were male, and 92% had ≥1 underlying comorbidity. Among those hospitalized (376 [78%]), 117 (31%) required mechanical ventilation, and 77 (20.5%) died by 28 days after diagnosis. Specific underlying comorbidities (age &gt;65 [adjusted odds ratio [aOR] 3.0, 95% confidence interval [CI] 1.7–5.5, P &lt; .001], congestive heart failure [aOR 3.2, 95% CI 1.4–7.0, P = .004], chronic lung disease [aOR 2.5, 95% CI 1.2–5.2, P = .018], obesity [aOR 1.9, 95% CI 1.0–3.4, P = .039]) and presenting findings (lymphopenia [aOR 1.9, 95% CI 1.1–3.5, P = .033], abnormal chest imaging [aOR 2.9, 95% CI 1.1–7.5, P = .027]) were independently associated with mortality. Multiple measures of immunosuppression intensity were not associated with mortality. Conclusions Mortality among SOT recipients hospitalized for COVID-19 was 20.5%. Age and underlying comorbidities rather than immunosuppression intensity-related measures were major drivers of mortality.

The Impact

OBJECTIVEClostridium difficileinfection (CDI) is common in solid organ transplant (SOT) recipients, but few studies have examined long-term outcomes. We studied the impact of CDI after SOT on mortality and transplant organ complication-related hospitalizations (TOH).METHODSSOT recipients ≥18 years of age with at least 1 year of posttransplant data were analyzed using the MarketScan database for 2007–2014. Patients who died within one year of transplant were followed until death. Patients were grouped as early CDI (ie, first occurrence ≤90 days posttransplant), late CDI (ie, first occurrence >90 days posttransplant) and controls (ie, no CDI occurrence during follow-up). The risk of mortality or TOH after CDI was evaluated using Cox and logistic regressions, respectively.RESULTSOverall, 96 patients had early CDI, 97 patients had late CDI, and 5,913 patients were used as controls. The risk for death was significantly higher in the early CDI group than the control group (hazard ratio [HR],1.92; 95% confidence interval [CI], 1.12–3.29;P=.018); there was no significant difference between the late CDI group and the control group (HR, 0.86; 95% CI, 0.38–1.94;P=.717). Both the early CDI group (odds ratio [OR], 2.19; 95% CI, 1.45–3.31;P<.001) and the late CDI group (OR, 4.36; 95% CI, 2.84–6.71;P<.001) had higher risk for TOH than the control group. For those patients who survived >90 days posttransplant, both the early CDI group (n=89) and the late CDI group (n=97) had increased risk for death or TOH during follow-up than the control group (n=5,734).CONCLUSIONThough our study could not prove causality, both early and late CDI occurrence in SOT recipients were associated with worse future outcomes than for SOT recipients without CDI.Infect Control Hosp Epidemiol2018;39:563–570

Abstract Background Epstein-Barr virus (EBV) donor positive (D+), recipient negative (R-) serostatus is a major risk factor for post-transplant lymphoproliferative disorder (PTLD) in adult solid organ transplant recipients (SOTR). Few studies have systematically characterized absolute organ transplant type-specific incidence, timing, and outcomes of PTLD in adult EBV D+R- SOTR. Methods We retrospectively assessed the incidence, timing, and associated morbidity and mortality of biopsy-confirmed PTLD (WHO classification) among consecutive adult SOTR between Jan 1, 2000 and Apr 30, 2018 at a single university center, and who had a minimum 2 years of follow-up. Antibodies to EBV (viral capsid antigen and nuclear antigen) were assessed in candidates and donors by FDA-cleared ELISA assay. Donors with unknown serology were considered seropositive based on the known prevalence of &gt;93% seropositivity in this donor population. Results Among 4,923 SOTR, prior to transplant, 4,770 (96.9%) were R+ (regardless of donor status), 144 (2.9%) were D+R-, and 9 (0.2%) were D-R-. PTLD incidence by last follow-up was higher among D+R- (15/144 [10.4%]) than R+ (61/4,770 [1.2 %]), P &lt; 0.0001, and occurred earlier after transplant (median 9.6 months [IQR 6.1-34.2] versus 35.1 months [IQR 7.1-73.1]), P= 0.003, respectively. Among D+R-, incidence was higher among recipients of non-kidney versus kidney organs (13/89 [14.6%] vs. 2/55 [3.6%], P = 0.05, respectively). Incidence in rank order was: pancreas (2/9 [22.2%]), lung (6/29 [20.7 %]), heart (2/21 [9.5%]), and liver (3/30 [6.7%]). PTLD histopathology was monomorphic in 9/15 [60%] and EBV-encoded RNA-1 (EBER-1) positive in 12/12 evaluable cases. Outcomes among the 15 PTLD cases included: graft failure without transplant in 3 (20%), graft failure with re-transplant in 2 (13.3%), and death within 6 months in 3 (20%). Table 1: Characteristics of the EBV Donor seropositive, Recipient seronegative (D+R-) cohort Figure 1: Cumulative Incidence of PTLD among the EBV D+R- cohort (all organs) Figure 2: Incidence of PTLD among the D+R- cohort, stratified by organ transplant type Conclusion Although rare overall, we identified a specific subgroup of adult SOT patients (EBV D+R- non-kidney recipients) whose absolute PTLD incidence and associated morbidity and mortality are high, and who should be targeted for future mechanistic or therapeutic studies.
