Incidence and outcomes of primary central nervous system lymphoma in solid organ transplant recipients.

ABSTRACT: Primary central nervous system lymphoma (PCNSL) risk is greatly increased in immunosuppressed human immunodeficiency virus-infected people. Using data from the US transplant registry linked with 17 cancer registries (1987-2014), we studied PCNSL and systemic non-Hodgkin lymphoma (NHL) in 288 029 solid organ transplant recipients. Transplant recipients had elevated incidence for PCNSL compared with the general population (standardized incidence ratio = 65.1; N = 168), and this elevation was stronger than for systemic NHL (standardized incidence ratio=11.5; N = 2043). Compared to kidney recipients, PCNSL incidence was lower in liver recipients (adjusted incidence rate ratio [aIRR] = 0.52), similar in heart and/or lung recipients, and higher in other/multiple organ recipients (aIRR = 2.45). PCNSL incidence was higher in Asians/Pacific Islanders than non-Hispanic whites (aIRR = 2.09); after induction immunosuppression with alemtuzumab (aIRR = 3.12), monoclonal antibodies (aIRR = 1.83), or polyclonal antibodies (aIRR = 2.03); in recipients who were Epstein-Barr virus-seronegative at the time of transplant and at risk of primary infection (aIRR = 1.95); and within the first 1.5 years after transplant. Compared to other recipients, those with PCNSL had increased risk of death (adjusted hazard ratio [aHR] = 11.79) or graft failure/retransplantation (aHR = 3.24). Recipients with PCNSL also had higher mortality than those with systemic NHL (aHR = 1.48). In conclusion, PCNSL risk is highly elevated among transplant recipients, and it carries a poor prognosis.

Project description:ImportanceLittle is known about the incidence and outcomes of Clostridioides difficile infection (CDI) in solid organ transplant (SOT) recipients.ObjectiveTo estimate the CDI incidence and outcomes in SOT recipients.Design, setting, and participantsA population-based cohort study was conducted using administrative health care data for all Ontario, Canada, residents who received organ allografts from April 1, 2003, to December 31, 2017; March 31, 2020, was the end of the study period.Main outcomes and measuresThe primary outcome was hospital admission with CDI diagnosis. The secondary outcomes included all-cause death, intensive care unit admission, acute kidney injury requiring dialysis, and fulminant CDI comprising any of the following: toxic megacolon, ileus, perforation, or colectomy. The association between short- vs long-term mortality (ie, death occurring within or after 90 days post-CDI) and the following variables was evaluated: age, sex, Deyo-Charlson Comorbidity Index, SOT type, early- vs late-onset CDI, fulminant CDI, intensive care unit admission, and acute kidney injury requiring acute dialysis.ResultsOverall, 10 724 SOT recipients (6901 [64.4%] men; median age, 54 [IQR, 44-62] years) were eligible. Kidney transplant was the most common SOT type (6453 [60.2%]). The median follow-up time was 5.0 (IQR, 2.3-8.8) years, resulting in 61 987 person-years of follow-up. A total of 726 patients (6.8%) were hospitalized with CDI. The 1-year CDI incidence significantly increased in annual cohorts (ie, from 23.1; 95% CI, 12.8-41.8 per 1000 person-years in 2004 to 46.7; 95% CI, 35.0-62.3 per 1000 person-years in 2017; P = .001). Clostridioides difficile was associated with a 16.8% rate (n = 122) of 90-day mortality. In patients who underwent kidney transplant, CDI was typically late-onset (median interval, 2.2; IQR, 0.4-6.0 years) compared with recipients of other organs. Acute kidney injury requiring dialysis was significantly associated with short-term (adjusted odds ratio [aOR], 1.86; 95% CI, 1.07-3.26) and long-term (adjusted hazard ratio [aHR], 1.89; 95% CI, 1.29-2.78) mortality, and late-onset CDI was also significantly associated with a greater risk of short-term (aOR, 4.26; 95% CI, 2.51-7.22) and long-term (aHR, 2.49; 95% CI, 1.78-3.49) mortality.Conclusions and relevanceIn this study, increasing CDI trends in annual cohorts of SOT recipients were observed. Posttransplant CDI was associated with mortality, and late-onset CDI was associated with a greater risk of death than early-onset CDI. These findings suggest that preventive strategies should not be limited to the initial months following transplantation. Comprehensive therapeutic approaches targeting acute kidney injury risk factors in SOT recipients may reduce short- and long-term post-CDI mortality.

Project description:ImportanceTransplant recipients experience high rates of adverse pregnancy outcomes; however, contemporary estimates of the association between solid organ transplantation and adverse pregnancy outcomes are lacking.ObjectiveTo evaluate the association between solid organ transplantation and adverse pregnancy outcomes and to quantify the incidence of allograft rejection and allograft loss during pregnancy.Data sourcesPubMed/MEDLINE, EMBASE and Scopus databases were searched from January 1, 2000, to June 20, 2024, and reference lists were manually reviewed.Study selectionCohort and case-control studies that reported at least 1 adverse pregnancy outcome in pregnant women with solid organ transplantation vs without solid organ transplant or studies that reported allograft outcomes in pregnant women with solid organ transplantation were included following independent dual review of abstracts and full-text articles.Data extraction and synthesisTwo investigators abstracted data and independently appraised risk of bias using the Newcastle Ottawa Scale. A random-effects model was used to calculate overall pooled estimates using the DerSimonian-Laird estimator. Reporting followed the Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guideline.Main outcomes and measuresPrimary pregnancy outcomes were preeclampsia, preterm birth (<37 weeks), and low birth weight (<2500 g). Secondary pregnancy outcomes were live birth rate, gestation, very preterm birth (<32 weeks), very low birth weight (<1500 g), and cesarean delivery. Allograft outcomes were allograft loss and rejection during pregnancy.ResultsData from 22 studies and 93 565 343 pregnancies (4786 pregnancies in solid organ transplant recipients) were included; 14 studies reported adverse pregnancy outcomes, and 13 studies provided data for allograft outcomes. Pregnancies in organ transplant recipients were associated with significantly increased risk of preeclampsia (adjusted odds ratio [aOR], 5.83 [95% CI, 3.45-9.87]; I2 = 77.4%), preterm birth (aOR, 6.65 [95% CI, 4.09-12.83]; I2 = 81.8%), and low birth weight (aOR, 6.51 [95% CI, 2.85-14.88]; I2 = 90.6%). The incidence of acute allograft rejection was 2.39% (95% CI, 1.20%-3.96%; I2 = 68.5%), and the incidence of allograft loss during pregnancy was 1.55% (95% CI, 0.05%-4.44%; I2 = 69.2%).Conclusions and relevanceIn this systematic review and meta-analysis, pregnancies in recipients of a solid organ transplant were associated with a 4 to 6 times increased risk of preeclampsia, preterm birth, and low birth weight during pregnancy. There was a low overall risk of graft rejection or loss during pregnancy.

Project description:BACKGROUND:Immunosuppressed solid organ transplant recipients [SOTRs] have elevated rates of certain rare cancers caused by viruses. Evaluating risk of rare cancers among SOTRs may provide etiological clues for additional cancers linked to poor immunity and viral infections. METHODS:We performed a cohort study of 262,455 SOTRs (1987-2014) from the US SOTR registry linked to 17 population-based cancer registries. First cancers in SOTRs were categorized using an established classification scheme based on site and histology. Standardized incidence ratios (SIRs) compared risk in SOTRs to the general population. We used Poisson regression to calculate incidence rate ratios (IRRs) according to immune-related SOTR characteristics, including time since transplant (i.e., duration of immunosuppression). All statistical tests are two-sided. RESULTS:We examined 694 distinct cancer subtypes, with 33 manifesting statistically significantly elevated SIRs (Bonferroni p?<?7.2 x 10-5). All 33 are rare (incidence <6 per 100,000 person-years) and several have known viral etiology (e.g. Merkel cell carcinoma (SIR = 24.7, 95%CI = 20.8 to 29.1). Additional cancers that were increased include squamous cell carcinomas (SCCs) of the lip (SIR range = 18.3-19.8), eye/adnexa (SIR = 13.8, 95%CI = 7.9 to 22.3), salivary gland (SIR = 9.3, 95%CI = 6.1 to 13.5), and nasal cavity/sinuses (SIR = 4.5, 95%CI = 2.8 to 6.8); sebaceous adenocarcinoma (SIR = 34.3, 95%CI = 26.3 to 44.0); malignant fibrous histiocytoma (15.4); and subtypes of bladder, kidney, lung, and colon cancer (SIR range = 3.2-13.3). Incidence of several cancers increased over time since transplant (ptrend<0.05), including SCCs of the lip, salivary gland, and anogenital sites. CONCLUSIONS:SOTRs experience elevated rates of several rare cancers. Because some of these cancers exhibit aggressive behavior with poor outcomes, it is important to further characterize the role of immunity and the potential involvement of oncogenic viruses to improve prevention and treatment.
