By April 26, 2020, infections related to coronavirus disease 2019 (COVID-19) affected people from 210 countries and caused 203,818 reported deaths worldwide. A few studies discussed the outcome of COVID-19 in kidney transplant recipients. This short series demonstrates our experience in managing COVID-19 disease in renal transplant patients in the absence of strong evidence. We report 8 cases of kidney transplant recipients infected with COVID-19 (median age = 48.5 years; range = 21–71 years), including 4 males and 4 females. The most frequently associated comorbidity was hypertension. The most common presenting features were fever and cough. The main radiological investigation was a portable chest X-ray. Other common features included lymphopenia, high C-reactive protein, and a very high ferritin level. Overall, 1 patient was managed as an outpatient, the remaining 7 required hospital admission, 1 of them referred to the intensive therapy unit. Management included supportive treatment (intravenous fluid therapy, monitoring renal function, and symptomatic treatment with or without ward-based oxygen therapy depending on oxygen saturation) and discontinuation of the antiproliferative immunosuppressive drugs. Seven patients recovered and discharged home to self-isolate. One patient required intensive care treatment and mechanical ventilation. Supportive treatment could be sufficient for the management or to be tried first. We also found that short hospital stay with self-isolation on discharge reduces the burden on the health service and protect the staff and the public.

ABSTRACT Cryptococcosis is the second most common invasive fungal infection reported in renal transplant recipients. Tissue granulomatous inflammation is necessary to contain Cryptococcus infection. This study aims to analyze the granuloma patterns and in situ expression of regulatory T (Treg) immune response in tissue samples from 12 renal transplant recipients with cryptococcosis. Fungal isolates were molecularly identified as Cryptococcus neoformans species complex. A detailed characterization of granulomas in tissue samples from 12 kidney transplant recipients with cryptococcosis was described by checking six lung and six skin biopsies by conventional histology and for immunohistochemical detection of CD4 and Treg markers: forkhead box P3 (FoxP3), interleukin (IL)-10 and transforming-growth factor (TGF)-β. Granulomas were classified as compact, loose or mixed. Patients with mixed (n = 4) and compact (n = 3) granulomatous inflammation patterns were associated with a better prognosis and presented a higher number of CD4+FoxP3+T cells compared to the group of patients with loose granulomas. In counterpart, three out of five patients with loose granulomas died with cryptococcosis. We suggest that Treg may have a protective role in the tissue response to Cryptococcus infection given its association with compact and mixed granulomas in patients with better clinical outcomes.

New-onset diabetes after transplantation (NODAT) is a common comorbidity after renal transplantation. Though metformin is the first-line agent for the treatment of type 2 diabetes, in renal transplant recipients, metformin is frequently avoided due to concerns about renal dysfunction and risk for lactic acidosis. Therefore, alternative first-line agents for the treatment of NODAT in renal transplant recipients are needed. Sitagliptin, a dipeptidyl-peptidase-4 (DPP-4) inhibitor, has a low incidence of hypoglycemia, is weight neutral, and, in a small study, did not affect immunosuppressant levels. However, long-term sitagliptin use for the treatment of NODAT in kidney transplant recipients has not been studied. We retrospectively analyzed renal transplant recipients diagnosed with NODAT and treated with sitagliptin to assess safety and efficacy. Twenty-two patients were started on sitagliptin alone. After 12 months of followup, 19/22 patients remained on sitagliptin alone with a significant improvement in hemoglobin A1c. Renal function and immunosuppressant levels remained stable. Analysis of long-term followup (32.5±17.8 months) revealed that 17/22 patients remained on sitagliptin (mean hemoglobin A1c < 7%) with 9/17 patients remaining on sitagliptin alone. Transplant-specific adverse events were rare. Sitagliptin appears safe and efficacious for the treatment of NODAT in kidney transplant recipients.

Abstract Background Sclerostin is a hormone contributing to the bone-vascular wall cross talk and has been implicated in cardiovascular events and mortality in patients with chronic kidney disease (CKD). We analyzed the relationship between sclerostin and mortality in renal transplant recipients. Methods 600 stable renal transplant recipients (367men, 233 women) were followed for all-cause mortality for 3 years. Blood and urine samples for analysis and clinical data were collected at study entry. We performed Kaplan–Meier survival analysis and Cox regression models considering confounding factors such as age, eGFR, cold ischemia time, HbA1c, phosphate, calcium, and albumin. Optimal cut-off values for the Cox regression model were calculated based on ROC analysis. Results Sixty-five patients died during the observation period. Nonsurvivors (n = 65; sclerostin 57.31 ± 30.28 pmol/L) had higher plasma sclerostin levels than survivors (n = 535; sclerostin 47.52 ± 24.87 pmol/L) (p = 0.0036). Kaplan–Meier curve showed that baseline plasma sclerostin concentrations were associated with all-cause mortality in stable kidney transplant recipients (p = 0.0085, log-rank test). After multiple Cox regression analysis, plasma levels of sclerostin remained an independent predictor of all-cause mortality (hazard ratio, 1.011; 95% CI 1.002–1.020; p = 0.0137). Conclusions Baseline plasma sclerostin is an independent risk factor for all-cause mortality in patients after kidney transplantation.

Royal Melbourne Hospital (RMH) performs over 140 kidney transplant operations annually. Kidney transplant recipients require regular medical review, which results in loss of time and costs from travel, particularly for regional patients, and places high demand on the hospital outpatient service. The RMH renal transplant unit initiated a telehealth service in 2016 to provide cost effective, patient-centred clinical care for regional patients. To date, 263 clinical reviews have been conducted via telehealth, potentially saving 203,202 kilometres in travel distance; 2771 hours in car travel time; an estimated AUD $31,048 in petrol savings and 51 tonnes CO2 equivalents of greenhouse gas emissions. Lessons learnt have included the importance of using technology that allows patients to access telehealth from their place of choice. The option of a joint consultation with local healthcare providers has facilitated the development of extended care networks for our patients. Incorporation of telehealth into our outpatient system has been achieved with the existing nephrology workforce, making it a sustainable long-term review option. Our renal transplant telehealth outpatient clinic has been a successful change in the way we provide care to regional patients. Formal comparison of clinical outcomes and the patient experience of telehealth versus in person reviews are underway.

Introduction: Both cytomegalovirus (CMV) infection and CMV disease have been linked with several long-term indirect effects in kidney transplant recipients. Research questions: We conducted a retrospective study to assess the association between cytomegalovirus disease and risks of death, shortterm cardiovascular events and graft loss in a cohort of renal transplant recipients. Design: The associations between CMV disease and death and cardiovascular events were determined using Cox regression models, while the association between viral disease and graft loss risk was analyzed through a competing risks regression according to the Fine and Gray method. Death with a functioning graft was considered as a competing risk event. Results: A total of 865 consecutive renal transplant recipients were included. The prevalence of seropositive donor/seronegative recipient (D+/R-) group was 89.9% with the remaining patients classified as seropositive recipient (R+). After median follow-up time of 24.4 months, CMV disease was not a risk factor for all-causes mortality (HR = 1.75; 95% CI 0.94-3.25), early cardiovascular events (HR = 0.54; 95% CI 0.16-1.82) or graft loss (subhazard ratio [the HR adjusted for competing risk of death with functioning graft] = 0.99; 95% CI 0.53-1.84). Conclusions: In this cohort with high prevalence of CMV IgG antibodies, we found no association between cytomegalovirus disease and risk of death or graft loss. The relationship between CMV and cardiovascular disease remains to be unraveled and probably corresponds to a multifactorial phenomenon involving individual risk factors and the immune response to infection rather than the virus effect itself.

Relevance. Retroperitoneal lymphocele is one of the most common complications in renal transplant recipients.Objective. To improve the results of treatment of kidney transplant recipients with retroperitoneal lymphocele by using a modern diagnostic and treatment algorithmMaterials and methods. Materials and methods: From June 2018 to March 2021 at the State Clinical Hospital named after S.P. Botkin, Moscow performed 174 kidney transplants from a posthumous donor. The accumulation of lymph in the retroperitoneal space was recorded in 24 patients, which amounted to 13.7%. Indications for surgical correction were found in 16 patients, which amounted to 9.1%. Computed tomography in 10 patients (62.5%) showed a wide adherence of the lymphocele cavity to the parietal peritoneum; peritoneum, the complexity of the planned laparoscopic surgery was assessed as high. These patients underwent laparoscopic peritoneal fenestration with ultrasound navigation. In 2 patients (12.5%), lymphocele adherence to the peritoneum was not revealed; these patients underwent open surgery.Results. Results: No relapses of lymphocele were detected after surgery. Mortality was not recorded. In the group of patients who underwent laparoscopic peritoneal fenestration with predictable low complexity, one postoperative complication was diagnosed – migration of the loop of the small intestine into the lymphocele cavity with subsequent infringement. The duration of hospitalization with laparoscopic intervention was 2.1 ± 0.43 (2–3) days, with open one it was 8.45 ± 3.25 (7–12) (p = 0.001).Conclusion. The use of a modern diagnostic and treatment algorithm can improve the results of treatment of kidney transplant recipients with retroperitoneal lymphocele.

Fatigue is one of the most distressing symptoms in renal transplant patients, causing functional impairment and worsening their quality of life. However, the mechanism by which fatigue affects physical activity is unclear. A cross-sectional study using a convenient sampling approach was utilized to investigate 665 kidney transplant recipients recruited from the transplantation centers of six general hospitals from July and September 2019. Structural equation modeling was used to examine the interaction among fatigue, fear of movement, physical self-efficacy, and physical activity. Our study found fatigue was directly negatively associated with physical activity and had an indirect impact on physical activity through the mediating effects of physical self-efficacy and fear of movement. These variables accounted for 44.4% of the variation in physical activity. Our findings alert healthcare providers for the importance of fatigue management for physical activity and focused attention on fear of movement and physical self-efficacy in renal transplant recipients.

Background. Fasting during the lunar month of Ramadan is mandatory to all healthy adult Muslims. Renal transplant recipients are often worried about the impact of fluid and electrolyte deprivation during fasting on the function of their allograft. We aimed to examine the effect of fasting Ramadan on the graft function in renal transplant recipients. Methods. This retrospective cohort study included patients who underwent kidney transplantation in our tertiary referral center. Baseline pre-Ramadan estimated glomerular filtration rate (eGFR), mean arterial pressure (MAP), and urinary protein excretion were compared to those during and after Ramadan within and between the fasting and non-fasting groups. Results. The study population included 280 kidney transplant recipients who chose to fast during the Ramadan month (June-July 2014) and 285 recipients who did not fast. In the fasting group, baseline eGFR did not change from that during or post-Ramadan (72.6±23.7 versus 72.3±24.5 mL/min/1.73 m2, P=0.53; and 72.6±23.7 versus 72±23.2 mL/min/1.73 m2, P=0.14, respectively). Compared to baseline, there were no significant differences between the fasting and the non-fasting groups in terms of mean percent changes in eGFR, MAP, and urinary protein excretion. Conclusion. Fasting during the month of Ramadan did not have significant adverse effects on renal allograft function.

Objectives: Proteinurea is one of the major causes of early graft rejection and high degree mortality in renal transplant patients. Our objective was to assess risk in post transplant patient for proteinurea and it’s appropriate management. Methods: This cross sectional study includes fifty adult kidney allograft recipients, transplanted in kidney transplant unit of Urology Department, Bangabandhu Sheikh Mujib Medical University in the period of January 2012 to December 2012. Results: In our series, proteinuria was detected in 44% of the renal transplant recipients in variant amount. In this study the male and female ratio was 7:3. There was a highly significant level of proteinuria in proteinuric group than that of non-proteinuric group [538.09 (313.36) mg/24 hr vs. 44.48 (23.39) mg/24 hr; p value <0.0001]. Acute rejection and death was found in 22% and 8% recipients respectively, which were more observed in proteinuric group. Conclusion: Based on these data, proteinuria should be monitored periodically at posttransplant period and investigation of the cause should be pursued vigorously.

The aim of our study is to determine characteristics and outcomes of kidney cancer in renal transplant recipients. MEDLINE® database was searched in June 2015 to identify cases of kidney cancer in renal transplant recipients. We include also a new case. Descriptive statistics were used for analysis. Forty-eight (48) recipients reported in 25 papers met the eligibility criteria. The median age was 47 years (range 9-66); 27% were females. Chronic glomerulonephritis, cystic kidney disease and hypertension were common indications for renal transplant. Among donors 24% were females and the median age was 52.5 years (17-73); 62% of kidney cancers were donor-derived. The median interval between transplant and cancer diagnosis was shorter for cancer of recipient versus donor origin (150 vs. 210 days). Clear cell carcinoma was diagnosed in 17%. 25% had metastasis at diagnosis. Kidney explantation or excision was done in 90% and 84% of cases with and without metastasis respectively. The median survival was 72 months. Actuarial 1-year and 5-year survival rates were 73.4% and 55.1% respectively. Among the recipients from 7 donors who subsequently developed malignancy, 57% were dead within a year. Kidney transplant recipients have a small risk of kidney cancer, which affects younger patients and occurs within a year of transplant, likely due to immunosuppression. Whether the use of older donors may increase the likelihood needs further investigation. The presence of metastasis, explantation or excision of affected kidney and development of cancer in donors predict outcomes. The results may guide patient education and informed decision-making.
