Yahav D, Gitman MR, Margalit I, Avni T, Leeflang MMG, Husain S. Screening for Latent Tuberculosis Infection in Solid Organ Transplant Recipients to Predict Active Disease: A Systematic Review and Meta-Analysis of Diagnostic Studies. Open Forum Infect Dis 2023; 10:ofad324. [PMID: 37559757 PMCID: PMC10407303 DOI: 10.1093/ofid/ofad324] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Accepted: 06/26/2023] [Indexed: 08/11/2023] Open
Abstract
BACKGROUND This is a systematic review and meta-analysis of diagnostic test accuracy studies to assess the predictive value of both tuberculin skin test (TST) and interferon-gamma release assays (IGRA) for active tuberculosis (TB) among solid organ transplantation (SOT) recipients. METHODS Medline, Embase, and the CENTRAL databases were searched from 1946 until June 30, 2022. Two independent assessors extracted data from studies. Sensitivity analyses were performed to investigate the effect of studies with high or low risk of bias. Methodological quality of each publication was assessed using QUADAS-2. RESULTS A total of 43 studies (36 403 patients) with patients who were screened for latent TB infection (LTBI) and who underwent SOT were included: 18 were comparative and 25 noncomparative (19 TST, 6 QuantiFERON-TB Gold In-Tube [QFT-GIT]). For IGRA tests taken together, positive predictive value (PPV) and negative predictive value (NPV) were 1.2% and 99.6%, respectively. For TST, PPV was 2.13% and NPV was 95.5%. Overall, PPV is higher when TB burden is higher, regardless of test type, although still low in absolute terms. Incidence of active TB was similar between studies using LTBI prophylaxis (mean incidence 1.22%; 95% confidence interval [CI], .2179-2.221) and those not using prophylaxis (mean incidence 1.045%; 95% CI, 0.2731-1.817; P = .7717). Strengths of this study include the large number of studies available from multiple different countries; limitations include absence of gold standard for diagnosis of latent TB and low incidence of active TB. CONCLUSIONS We found both TST and IGRA had a low PPV and high NPV for the development of active TB posttransplant. Further studies are needed to better understand how to prevent active TB in the SOT population.

Abstract
Tuberculosis (TB) in kidney transplant (KT) recipients is an important opportunistic infection with higher incidence and prevalence than in the general population and is associated with important morbidity and mortality. We performed an extensive literature review of articles published between 1 January 2000 and 15 June 2022 to provide an evidence-based review of epidemiology, pathogenesis, diagnosis, treatment and outcomes of TB in KT recipients. We included all studies which reported epidemiological and/or outcome data regarding active TB in KT, and we approached the diagnostic and treatment challenges according to the current guidelines. Prevalence of active TB in KT recipients ranges between 0.3–15.2%. KT recipients with active TB could have a rejection rate up to 55.6%, a rate of graft loss that varies from 2.2% to 66.6% and a mortality rate up to 60%. Understanding the epidemiological risk, risk factors, transmission modalities, diagnosis and treatment challenges is critical for clinicians in providing an appropriate management for KT with TB. Among diagnostic challenges, which are at the same time associated with delay in management, the following should be considered: atypical clinical presentation, association with co-infections, decreased predictive values of screening tests, diverse radiological aspects and particular diagnostic methods. Regarding treatment challenges in KT recipients with TB, drug interactions, drug toxicities and therapeutical adherence must be considered.

Abstract
OBJECTIVE This study investigated the clinical characteristics of patients with tuberculosis (TB) following renal transplantation (RT) in order to identify markers or signs that can facilitate early diagnosis. METHODS A retrospective analysis was performed on 12 cases of Mycobacterium tuberculosis infection treated at our hospital between 2005 and 2020. RESULTS The incidence of TB after RT at our hospital was 0.9%, and the median postoperative onset time was 22 months. The average age of patients included in our analysis was 44.2 ± 9.4 years; 11 of the 12 patients were male, and most patients had (low) fever as the first or only manifestation. Five patients had respiratory symptoms; 5 had typical computed tomography (CT) presentation; and 2 had a confirmed history of TB. Two sputum smears from 12 patients were positive by acid fast staining, and M. tuberculosis was detected in peripheral blood samples by metagenomic next-generation sequencing (NGS). One patient had a positive result in the purified protein derivative (PPD) test, 7 were positive with the interferon gamma release assay (IGRA), 8/12 patients were confirmed to have TB infection by NGS and 1 was confirmed positive by lung biopsy. CONCLUSION Because of the use of immunosuppressive agents, most patients with TB following RT have atypical clinical symptoms and CT findings, and may have a high probability of a false negative result with the traditional PPD test and a low probability of M. tuberculosis detection, making early diagnosis difficult. Therefore, in RT recipients with prolonged fever of unknown origin and unusual clinical manifestations, especially those who are unresponsive to antibiotic treatment, a diagnosis of TB should be considered. The interferon gamma release assay and NGS are relatively new detection methods with high sensitivity and specificity; these along with regular, repeated testing by various approaches can aid the early diagnosis of TB.

Abstract
INTRODUCTION Tuberculosis (TB) is a possible serious complication of solid organ transplantation, associated with high mortality and morbidity. Post-transplant TB has varied pathogenesis with many approaches to its prevention, which is the most important way to reduce its incidence. Treatment of TB in organ recipients is challenging because of drug toxicity and interaction with immunosuppressants. CASE REPORT an 18-year-old woman that underwent kidney transplantation from a deceased donor and was discharged with fair renal function was readmitted at 37th postoperative day with fever. CT showed signs of miliary TB and fluid collection besides graft fistulization through the skin. The patient presented positive BAAR in the drained fluid and Koch's bacillus in the urine. She was treated with a four-drug regimen (rifampicin, isoniazid, pyrazinamide, and etambutol), with great response and preserved graft function. We were informed that the recipient of the contralateral kidney also presented post-transplant TB, implying in a donor-derived origin. CONCLUSION TB is an important differential diagnosis for infectious complications in patients after solid-organ transplantation, especially in endemic regions. Its initial clinical presentation can be unspecific and it should be suspected in the presence of fever or formation of fluid collections. The suspicion of TB is the key to early diagnosis and satisfactory outcomes in post-transplant TB.

Abstract
Large-scale evidence comparing the risk of Mycobacterium tuberculosis (TB) between kidney transplant (KT) recipients and dialysis patients is warranted. This is a nationwide retrospective cohort study based on the claims database of South Korea where a moderate prevalence of TB is reported. We included incident KT recipients from 2011 to 2015 and compared their active TB risks with 1:1 matched dialysis and general population control groups, respectively. The risk of incident active TB was assessed by multivariable Cox regression. Associations between active TB and posttransplant death or death-censored graft failure were investigated. The number of matched subjects included in each of the study groups was 7462. The KT group showed a significantly higher risk of active TB than the general population group (hazard ratio [HR] 3.39 [1.88-6.10]), whereas it showed a similar risk to that of the dialysis group (HR 0.98 [0.73-1.31]). In KT patients, active TB was a significant risk factor for both death (HR 2.33 [1.24-4.39]) and death-censored graft failure (HR 2.26 [1.39-3.67]). Although KT recipients may not have to burden the additional risk of active TB when compared with dialysis patients in recent medicine, active TB should not be overlooked as it is associated with a worse prognosis in posttransplant patients.

Abstract
PURPOSE OF REVIEW Due to impaired immune response, solid organ transplant (SOT) recipients are susceptible to tuberculosis (TB) and its subsequent morbidity and mortality. Current prevention strategies, diagnostic and treatment approach to TB infection in donors and recipients were reviewed in this article. RECENT FINDINGS Screening of latent tuberculosis infection (LTBI) in donors and recipients is the cornerstone of TB-preventive strategy in recipients and requires an assessment of TB risk factors, TB-specific immunity testing, and radiographic evaluation. Interferon-gamma release assay has superseded the tuberculin skin test in LTBI evaluation despite its recognized limitations. LTBI treatment should be offered to transplant candidates and living donors before transplantation and donation, respectively. Diagnosis of TB disease can be challenging because of nonspecific clinical presentation in the recipient and is limited by the sensitivity of current diagnostics. The approach to LTBI and TB disease treatment is similar to the general population, but can be challenging because of potential drug interactions and toxicities. SUMMARY The appropriate evaluation of donors and recipients for TB can mitigate posttransplant TB disease. Current approaches to diagnosis and treatment parallels that of immunocompetent hosts. Future research evaluating existing and novel diagnostics and treatment in transplant recipients is needed.

Abstract
INTRODUCTION Tuberculosis (TB) is considered as a serious complication of organ transplant; therefore, the detection and appropriate treatment of active TB infection is highly recommended for the reduction of mortality in the future. The aim of this review was to conduct a systematic review and meta-analysis assessing the prevalence of active TB infection in transplant recipients (TRs). MATERIAL AND METHODS Electronic databases, including MEDLINE (via PubMed), SCOPUS and Web of Science were searched up to December 24, 2017. The prevalence of active TB was estimated using the random effects meta-analysis. Heterogeneity was evaluated by subgroup analysis. Data were analyzed by STATA version 14. RESULTS The pooled prevalence of post-transplant active TB was estimated 3% [95% CI: 2-3]. The pooled prevalence of active TB in different transplant forms was as follows: renal,3% [95% CI: 2-4]; stem cell transplant (SCT), 1% [95% CI: 0-3]; lung, 4% [95% CI: 2-6]; heart, 3% [95% CI: 2-4]; liver, 1% [95% CI: 1], and hematopoietic stem cell transplant (HSCT), 2% [95% CI: 1-3]. The prevalence of different clinical presentations of TB was as follows: pulmonary TB (59%; 95% CI: 54-65), extra pulmonary TB (27%; 95% CI: 21-33), disseminated TB (15%; 95% CI: 12-19) and miliary TB (8%; 95% CI: 4-13). The pooled prevalence of different diagnostic tests was as follows: chest X-ray, 57% [95% CI, 46-67]; culture, 56% [95% CI, 45-68]; smear, 49% [95% CI, 40-58]; PCR, 43% [95% CI, 40-58]; histology, 26% [95% CI, 20-32], and tuberculin skin test, 19% [95% CI, 10-28]. CONCLUSION A high suspicion level for TB, the early diagnosis and the prompt initiation of therapy could increase the survival rates among SOT patients. Overall, renal and lung TRs appear to have a higher predisposition for acquiring TB than other type of recipients. Monitoring of the high-risk recipients, prompt diagnosis, and appropriate treatment are required to manage TB infection among TRs especially in endemic areas.

Abstract
RATIONALE Active tuberculosis constitutes a relevant risk for kidney transplant recipients. In contrast to immunocompetent hosts, kidney transplant recipients often show atypical presentation and course of the disease impeding diagnosis. Especially extrapulmonary or disseminated infection is more frequent and can resemble malignant processes. However, reactivation of tuberculosis mostly develops within the early post-transplant course, whereas malignancies are predominantly long-term complications. We report a case of disseminated abdominal tuberculosis developing 10 years after kidney transplantation and review the underlying literature. PATIENT CONCERNS AND DIAGNOSES A 51-year-old lady presented with epigastric pain, diarrhea, weight loss and night sweats 10 years after deceased-donor kidney transplantation. An epigastric as well as multiple peritoneal masses were found suspicious of a cancer of unknown primary. Colonoscopy revealed a colon tumor with the biopsy showing no dysplasia but histiocytic and granulomatous infiltration with acid-fast bacilli. Mycobacterium tuberculosis was detected in the biopsy and stool and disseminated abdominal tuberculosi was diagnosed. INTERVENTIONS AND OUTCOMES With anti-tuberculosis therapy, the masses regressed, and all cultures became sterile, sparing graft function. LESSONS This case emphasizes how variable and unspecific the presentation of tuberculosis in kidney transplant recipients may be and that tuberculosis constitutes a relevant risk also in the long-term post-transplant course.

Long-Term Outcomes among Kidney Transplant Recipients and after Graft Failure: A Single-Center Cohort Study in Brazil. BIOMED RESEARCH INTERNATIONAL 2019; 2019:7105084. [PMID: 31061825 PMCID: PMC6466891 DOI: 10.1155/2019/7105084] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/15/2018] [Revised: 03/12/2019] [Accepted: 03/14/2019] [Indexed: 12/29/2022]
Abstract
Background The results of kidney transplantation are impacted by the categories of events responsible for patient death and graft failure. The objective of this study was to evaluate the causes of death and graft failure and outcomes after graft failure among kidney transplant recipients. Methodology A retrospective cohort study was conducted with 944 patients who underwent kidney transplantation. Outcomes were categorized in a managed and hierarchical manner. Results The crude mortality rate was 10.8% (n=102): in 35.3% cause of death was infection, in 30.4% cardiovascular disease, and in 15.7% neoplasia and in 6.8%, it was not possible to determine the cause of death. The rate of graft loss was 10.6%. The main causes of graft failure were chronic rejection (40%), acute rejection (18.3%), thrombosis (17.3%), and recurrence of primary disease (16.5%). Failures due to an acute rejection occurred earlier than those due to chronic rejection and recurrence (p<0.0001). As late causes of graft loss, death with the functioning kidney occurred earlier than recurrence and chronic rejection (p=0.008). The outcomes after graft failure were retransplantation in 26.1% and death in 21.4%, at a mean of 25.5 and 21.4 months, respectively. Conclusion It was possible to identify more than 90% of the events responsible for the deaths of transplanted patients, predominantly infectious and cardiovascular diseases. Among the causes of graft failure, chronic and acute rejections and recurrence were the main causes of graft failure which were followed more frequently by retransplantation than by death on dialysis.

Abstract
Patients with chronic kidney disease have impaired immunity that increases their risk of infection. Increased incidence of mycobacterial infections, in particular Mycobacterium tuberculosis, is described in patients undergoing hemodialysis and peritoneal dialysis as well as after kidney transplantation in low-prevalence and high-prevalence settings. Diagnosis of this infection can be challenging because of atypical presentations that may lead to treatment delay and, consequently, increased mortality; however, recent advances in molecular testing have improved diagnostic accuracy. It is imperative to try to identify those patients at increased risk and offer adequate prophylaxis. There are controversies and insufficient data regarding treatment agents, duration, and dosages. Most studies in nontuberculous mycobacteria are based on case series and retrospective studies.

Abstract
Solid organ transplant recipients are at an increased risk of tuberculosis and transplant candidates should be screened early in their evaluation with a detailed history, tuberculin skin test or tuberculosis interferon-gamma release assay, and chest radiograph. For latent tuberculosis treatment, isoniazid and rifamycin-based regimens have advantages and disadvantages; treatment decisions should be customized. Tuberculosis after solid organ transplantation generally occurs after months or years; early infections should raise the possibility of donor-derived infections. Tuberculosis diagnosis and treatment in solid organ transplant recipients may be complicated by protean manifestations, drug interactions, and adverse drug reactions.

The incidence of end-stage renal disease has continued to increase. Similarly, the number of patients living with a functioning renal allograft has also increased. Transplantation has improved with advances in surgical techniques, immunosuppression, and better control of comorbid conditions. Transplantation is transformative and offers the greatest potential for restoring a healthy, productive, and durable life to appropriately selected patients. This article describes factors to address in selection of renal transplant candidates and discusses commonly encountered perioperative events. Paramount to selecting appropriate candidates is the collaboration between a multidisciplinary team focused on a systematic process guided by protocols and common practices.
