tuberculosis in renal transplant patients

Tuberculosis (TB) infection of the genitourinary tract (GU TB) is rare in renal transplant recipients, with only a few published case series. GU TB is difficult to diagnose with or without immunosuppression but must always be suspected in any patient with unexplained sterile pyuria. As GU TB is associated with graft rejection, prompt diagnosis and treatment are vital. Treatment is challenging, as rifampicin, the most effective drug used to treat tuberculosis, is a significant inducer of cytochrome P-450 3A metabolism, with the potential to cause significant reductions in the serum levels of calcineurin inhibitors...

Introduction: Infection with SARS-CoV-2 increases the risk of acute graft dysfunction (AGD) in renal transplant recipients (RTR), and the risk of concurrently presenting with opportunistic infections is also increased. There is no current consensus on the management of immunosuppression during SARS-CoV-2 infection in RTR. Case Presentation . A 35-year-old male RTR from a living related donor presented with SARS-CoV-2 infection (January 2021). Two months later, despite alterations to his immunosuppression regimen (tacrolimus (TAC) was reduced by 50%, and the mycophenolic acid (MMF) was suspended with the remission of symptoms), the patient presented with pulmonary tuberculosis, pneumonia due to respiratory syncytial virus (RSV), cytomegalovirus (CMV) pneumonitis, and histoplasmosis (HP)...

Tuberculosis (TB)-associated glomerulonephritis is difficult to diagnose that usually presents with hematuria, proteinuria, edema, hypertension, or renal insufficiency, which is similar to symptoms of primary glomerulonephritis. Membranous nephropathy (MN) is uncommonly seen in TB patients. We report a case of a 30-year-old female with Koch's chest who developed anti-phospholipase A2 receptor antibody-positive MN after initiation of anti-Koch's therapy and resolved after completion of anti-Koch's therapy.

The incidence of Nocardiosis was c.1-2 per 100,000 population worldwide in the early 2000s. Co-infection with Nocardia and MOTT (mycobacterium other than tuberculosis) is even more uncommon and has been described only in the setting of pulmonary manifestations in an immunocompromised (HIV) patient. However, over the last two decades, the incidence of Nocardiosis has increased to about 7-8 per 100,000 population, with pulmonary manifestations being the most common. With this background, we present the case of a middle-aged immunosuppressed man (post renal transplant with rejection), who presented with fever with extensive skin lesions and features suggestive of sepsis, without pulmonary involvement...

OBJECTIVE: The aim of this study was to estimate global TB incidence in patients with CKD. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method was followed to perform the study. Electronic and gray literature sources were investigated for studies published between 2000 and 2021. The Joanna Briggs Institute critical appraisal checklist was used to assess the quality of the studies, and STATA version 16 was used for analysis...

We present a case of a young kidney transplanted man. He was admitted with lymphadenopathy, fluctuating fever and night sweats 2 months after a cat bite. After admission, he developed severe pain around his right hip. An 18 F-fluorodeoxyglucose (FDG)-positron emission tomography/CT revealed intense FDG-uptake in lymph nodes, spleen and bone, suggestive of lymphoma. An extracted lymph node showed confluent granulomas, microabscesses with neutrophils and scattered multinucleated giant cells histologically. The patient had history of latent tuberculosis and proteinase 3 -anti-neutrophil cytoplasmic antibodies associated (PR3-ANCA) vasculitis, making differential diagnostic considerations complicated...

Cyclospora spp. is an important cause of traveler's diarrhea or water and food-borne diarrhoeal diseases. We present an interesting but rare case report of cyclosporiasis in a 51-year-old male who had undergone renal allograft transplant six years ago. He also had a past history of tuberculosis, cytomegalovirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and hepatitis C infection and was being treated with immunosuppressants. The patient had a prolonged history of gastrointestinal manifestations with recent acute onset of watery diarrhea associated with abdominal cramps...

BACKGROUND AND OBJECTIVES: In patients with chronic kidney disease the risk of developing Tuberculosis is increased, while the presentation is often atypical making the diagnosis more difficult. The aim of this study is to describe the presentation of Tuberculosis in dialysis and kidney transplant patients, including the range of diagnostic approaches and the utility of different sample types. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS: In this retrospective study, case records of dialysis and kidney transplant patients were reviewed, including all those treated for Tuberculosis between January 2009 and December 2020...

We report a case of disseminated histoplasmosis and COVID-19 infection in a renal transplant recipient in Argentina. The patient exhibited respiratory symptoms, and a chest computed tomography scan (CT) showed multiple bilateral centrilobular opacities with a tree-in-bud pattern in both lobes. The patient was initially treated as having bacterial community-acquired pneumonia, and then tuberculosis. A month later, histoplasmosis was diagnosed, and Histoplasma capsulatum LAmB clade was isolated from sputum, skin and oral lesions...

Background With tuberculosis (TB) being among the top 13 leading cause of death and second leading infectious disease killer next to COVID-19 globally, there is a need for continued study and a better understanding of the risk factors and management approaches. One in five tuberculosis (TB) deaths occurs in individuals who have contracted human immunodeficiency virus (HIV). However, other risk factors play a role in its morbidity pattern. Therefore, descriptions of these comorbidities between TB, HIV, and other risk factors such as diabetes are needed...

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...

Severe lactic acidosis, a mitochondrial toxicity caused by the recommended standard dosage of linezolid (LZD), may occur in patients with impaired renal function. We describe an adult male who underwent kidney transplantation with stably impaired renal function, severe dyspnea, and abdominal discomfort. He received a standard oral dose of LZD (600 mg twice daily) and azithromycin for three weeks with a reduced immunosuppressant dose due to pulmonary non-tuberculosis mycobacterial infection. He was alert and afebrile, with a blood pressure of 140/60 mmHg...

Introduction: Identification of latent tuberculosis (TB) infection is important in kidney transplant candidates. Due to the absence of a gold standard, both tuberculin skin test (TST) and interferon-gamma release assays (IGRA) are used to screen patients. The aim of this study was to evaluate the agreement of these two tests in patients undergoing renal transplantation. Materials and Methods: Two hundred kidney transplant candidates at a referral center in 2014-2017 were included in this study...

OBJECTIVE: Granulomatous interstitial nephritis is a rare finding, and etiology differs by geography. We aimed to investigate the distribution of causes of granuloma/granulomata in the kidney and renal survival of these patients in a tertiary care hospital in Western Turkey. MATERIAL AND METHOD: Medical records of adults who underwent a kidney biopsy procedure in our institution between January 2000 and June 2019 were reviewed. Pathology reports were searched for biopsies where a granuloma was identified...

Despite the high prevalence of tuberculosis (TB) in developing countries, pancreatic TB remains a rare disease. Pancreatic TB usually presents as fever, night sweats, and abdominal pain in an immunocompromised individual. We present a case of a patient with end-stage renal disease undergoing pre-transplant workup who had an incidental finding of a pancreatic mass and necrotic peri-pancreatic lymph nodes on a CT scan. The patient was diagnosed via endoscopic ultrasound-guided biopsy as pancreatic TB. Anti-TB therapy was started with positive results...

INTRODUCTION: Renal transplant recipients are at high risk of tuberculosis (TB). We started isoniazid (INH) prophylaxis of 1 year duration in all renal transplant recipients from April 2009. Our aim was to assess the incidence of TB on INH prophylaxis and its tolerability. METHODS: This was a retrospective observational study. The files of renal transplant recipients from April 2009 to December 2011 were reviewed till June 2015. We noted the incidence of TB, INH tolerability, and development of resistance...

BACKGROUND: Along with the medical development, organ transplant patients increase dramatically. Since these transplant patients take immunosuppressants for a long term, their immune functions are in a suppressed state, prone to all kinds of opportunistic infections and cancer. However, it is rarely reported that the kidney transplant recipients (KTRs) have pulmonary tuberculosis and lung cancer simultaneously. CASE PRESENTATION: A 60-year-old male was admitted because of persistent lung shadow for 2 years without any obvious symptom 8 years after renal transplant...

Objective : To present the first Egyptian clinical practice guideline for kidney transplantation (KT). Methods : A panel of multidisciplinary subspecialties related to KT prepared this document. The sources of information included updates of six international guidelines, and review of several relevant international and Egyptian publications. All statements were graded according to the strength of clinical practice recommendation and the level of evidence. All recommendations were discussed by the panel members who represented most of the licensed Egyptian centres practicing KT...

Multidrug-resistant tuberculosis (MDR-TB) is caused by mycobacterium tuberculosis that is resistant to isoniazid (INH) and Rifampin (Rif). The use of immunosuppressive drugs in solid organ transplant (SOT) recipients can increase the risk of TB. Management of MDR-TB is quite challenging in general population with poor compliance due to lengthy treatment duration and drug toxicities. New drugs as well as shorter regimen have been used to increase the likely hood of adherence. The experience of treating MDR-TB in transplant recipients is limited...

Hypercalcemia is common in patients after kidney transplantation (KTx) and is associated with persistent hyperparathyroidism in the majority of cases. This retrospective, single-center study evaluated the prevalence of hypercalcemia after KTx. KTx recipients were evaluated for 7 years after receiving kidneys from living or deceased donors. A total of 301 patients were evaluated; 67 patients had hypercalcemia at some point during the follow-up period. The median follow-up time for all 67 patients was 62 months (44; 80)...
