Indian Journal of Transplantation 2020 14(4):275-282

Background: The literature on the impact of comorbidities on the severity and outcome of COVID-19 in kidney transplant patients is limited. We aimed to review the same. Methods: We conducted this review as per Preferred Reporting Items for Systematic Reviews and Meta-Analysis recommendations. PUBMED, Embase, Scopus, and Science Direct were searched for studies, available online till May 31, 2020. Studies reporting comorbidities, clinical course, and outcome of each kidney transplant patient with COVID-19 were included. Studies on any other organ transplant, recommendations, or review articles were excluded. The impact of comorbidities on severity and outcome was assessed. The study appraisal was done using Joanna Briggs Institute Critical Appraisal Checklist. Continuous variables were compared using Mann–Whitney U-test. Categorical variables were compared using Fisher's exact test. A univariate and multivariate logistic regression for predictors of severity and outcome, was done. P < 0.05 was considered statistically significant. The study protocol was registered with PROSPERO (CRD42020190114). Results: We analyzed 19 studies (56 patients) out of the 355 identified. The most common comorbidity was hypertension (83.92%). Nearly 30.35% of the patients had severe clinical course. The mortality rate was 19.64%. Advanced age was statistically significantly associated with severe course (P = 0.0173) and death (P = 0.0005). Men were more likely to have nonsevere course (P < 0.0001). No comorbidity had any impact on the severity or outcome. Patients with severe disease had higher odds of dying (P = 0.002). Conclusions: Comorbidities were not found to have any significant impact, hence the contribution of immunosuppression toward the severity of COVID-19 needs to be studied. Ours is the first review to assess the impact of comorbidities in kidney transplant patients with COVID-19 but limited by the number of patients.

Background: In India, 8.27 million documented cases of COVID 19 and a total of 123K deaths have been reported till October 2020. We were able to estimate the clinical consequences of SARS CoV 2 in 16 patients over a period of 5 months. The disease prevalence and mortality rate observed in transplant recipients were found to be higher than in the general population. Aims and Objectives: A retrospective analysis of COVID 19 infections in kidney transplant recipients and the outcome. Materials and Methods: A single centre observational study of all patients who have undergone kidney transplant between March 2001 and December 2019 and documented evidence of SARS CoV 2 infection between March 2020 and October 2020. From a large cohort of 720 kidney transplant recipients, 16 recipients who developed COVID 19 infection were studied. They were all on maintenance immunosuppression in varying doses. None of the patients in this cohort had any recent episodes of cellular rejection requiring heightened immunosuppression. The vintage of the transplant varied from 9 to 192 months. Results: Acute kidney injury was identified in two patients. Eight patients were home quarantined and eight patients were hospitalized. All patients had a reduction in immunosuppression during the covid 19 infection dosage based on the severity of the disease. Out of the hospitalized patients, three died, two of whom had stable functioning grafts and the cause of death was identified as acute lung injury 1 patient had post covid ACR which was treated with Injection. Methyl Prednisolone. Conclusions: In our study, 2.22% developed COVID-19 disease and the mortality rate was 18.75% among those who developed COVID-19. The disease prevalence and mortality rate observed in transplant recipients were found to be higher than in the general population. Obesity, diabetes mellitus, and systemic hypertension were identified as independent risk factors.

Objectives: Diagnosis of active cytomegalovirus (CMV) infection in hematopoietic stem cell (HSC)-transplanted patients is essential because of the serious complications it causes, especially CMV disease. Such diagnosis allows the initiation of a preemptive antiviral therapy, which avoids the development of such disease. In this retrospective study made as a part of routine work for transplanted patients, we compared two diagnosis testing for CMV-active infection such as pp65 CMV antigenemia and a quantitative real-time polymerase chain reaction (QPCR). Our purpose was to assess the contribution of these tools to the diagnosis and monitoring of active CMV infections. Materials and Methods: Five hundred and fifty-eight and 156 samples belonging to 24 HSC transplanted patients were, respectively, tested by antigenemia and QPCR. Results: For the 156 samples analyzed by both testing, a number of positive samples by a QPCR were higher than that by antigenemia (44.8% vs. 13%), with a statistically significant difference (P < 0.0001). A statistically significant correlation between viral loads of these two testing was also found (rs = 0.765). In median, QPCR becomes positive 14 days before antigenemia (P < 0.0001) and its positivity lasts for 91 days, whereas antigenemia positivity lasts only for 56 days (P < 0.001). No statistically significant difference was found between the results of these two testing in CMV disease cases. Conclusions: QPCR is a rapid, standardized assay, which permits a precocious detection of CMV DNA. Kinetic of DNA evolution is a reliable diagnostic tool and more effective than antigenemia-based assays in monitoring CMV infection.

Introduction: There are limited data on the symptoms of immune-suppressive therapy after transplant on Indian patients and how tacrolimus blood level correlates with graft function and its adverse effects. This study was planned to study these factors. Materials and Methods: The study was conducted as a prospective longitudinal study. Adult patients who underwent the live renal transplant and matched the inclusion criteria from March 2018 to April 2019 were enrolled for the study. Trends of all the parameters were analyzed and their correlation was done with corresponding tacrolimus blood levels. Blood for tacrolimus level was collected at d1, 5, 15, 30, 90, and 180, and values of serum creatinine, diabetes status, hypertensive status, lipid profile, infection occurrence, and liver function tests were recorded at the same time. The subjective symptom occurrence was also recorded by Modified Transplant Symptom Occurrence and Symptom Distress Scale questionnaire at 3 months. Results: The mean age of the study population was 33.7 ± 10.1 years. The incidence of infection was highest at 48% in the 1–3 month period. The incidence of posttransplant diabetes mellitus (PTDM) was 13.7%. Patients requiring antihypertensive decreased from 93.1% immediate posttransplant to 51.5% after 6 months of transplant. There was an increase in posttransplant triglyceride levels, total cholesterol, and low-density lipoprotein level with only high-density lipoprotein showing a protective trend. Liver functions did not show any derangements during the study period. There was no significant correlation between any of the adverse effects and tacrolimus blood levels. Excessive appetite was the most commonly experienced symptoms whereas tremor was the most distressing one. There was a statistically significant increase in symptoms experienced in patients whose tacrolimus blood level was above the normal level for that period. Conclusion: Our study showed no significant correlation between blood levels of tacrolimus and graft function and also with hypertension, dyslipidemia, PTDM, and incidence of posttransplant infections. The incidence of adverse effects was significantly higher in patients who had tacrolimus blood levels higher than recommended.

Indian Journal of Transplantation 2020 14(4):306-312

Objective: Lymphatic complications (lymphorrhea or lymphocele) are one of the most common and frustrating complications of renal transplantation. It was well documented in literatures that excessive lymphatic leak in the early postoperative period leads to lymphorrhea, which may transform into lymphocele. Povidone-iodine has been used as a sclerosant in lymphocele management for the past 30 years. In this study, our aim is to establish the role of povidone-iodine to prevent lymphorrhea after kidney transplant surgery. Materials and Methods: A total of 106 (live donor transplant patient = 63 and deceased donor transplant patient 43) patients had undergone renal transplantation from May 2019 to May 2020. Those patients were randomized into three groups – Group A (n = 35): where 1% povidone-iodine was used, Group B (n = 35): where 5% povidone-iodine was used, and Group C (n = 36): control group, where povidone-iodine was not used. Fifty milliliters of 1% or 5% povidone-iodine was used to wash the bed and kept for 5 min in contact with the bed and again 1% (Group A) or 5% (Group B) povidone-iodine wash was given after completion of ureteroneocystostomy and was kept for 5 min. Results: On postoperative day 6, there is a statistically significant decrease in drain output in the 5% and 1% povidone-iodine groups in comparison with the control group, but no statistically significant difference exists between 5% versus 1% povidone-iodine group. Conclusion: Intraoperative instillation povidone-iodine is a cheap, safe, and very effective procedure to prevent lymphorrhea following renal transplant surgeries.

Background: Kidney transplantation (KT) is widely accepted as most successful treatment option for patients with end-stage kidney disease (ESKD) for better survival and quality of life for both children as well as adults. Data scarcity on long term outcome of living donor (LD) versus deceased donor (DD) pediatric KT in developing countries prompted us to review our experience. Aims and Objectives: To determine(1) long term graft, (2)patient survival outcome and (3) rejection episodes in LD versus DD pediatric KT in developing country. Patients and Methods: This was a retrospective observational analysis of 151 LD and 37 DD pediatric renal transplants (age ≤18 years) performed at a tertiary care center between 1998 and 2011. This study was under taken to evaluate long term patient and graft survival, rejection episodes and other complications. Demographic details for all patients was retrieved. Kaplan-Meier curves were used for survival analysis. Results: Over a mean follow-up of 4.2 ± 3.61 years, one-, five- and ten- year death-censored graft survival in LDKT was 87.4%, 72.1%, 72.1% and patient survival was 92.5%, 80.9%, 75.1% respectively; 19.8% (n = 30) patients had biopsy proven acute rejection (BPAR) and 17.8% (n = 27) patients died, mainly due to infections (n = 12). In DDKT, over mean follow-up of 3.93 ± 3.5 years, one-, five- and ten-year death-censored graft survival was 90.4%, 86.4% ,73.3% and patient survival was 83.4%, 67.9%, 67.9 %, respectively; 21.6% (n = 8) patients had BPAR and 27% (n =10) patients died, mainly owing to infections (n = 6). Conclusion: LDKT or DDKT in children has acceptable graft function with patient/graft survival over long-term follow-up, encouraging to develop sustained deceased donor program in developing countries. However, infections are major cause of morbidity and mortality.


Establishing a deceased donor transplantation program and its impact in a public sector hospital in India – A single centre experience from India
JIPMER Deceased Donor Transplantation Committee (JDDTC)

Indian Journal of Transplantation 2020 14(4):321-332

Introduction: Organ transplantation is growing in India but is mostly dependent on living donors. Deceased donor organ procurement has grown in certain parts of the country in the past decade. However, brain death certification and organ procurement predominantly happen in private health-care sector, with less contribution from public sector hospitals. Expanding the infrastructure for deceased donor transplantation program, especially in the public sector hospitals, is likely the most important step toward improving deceased donor organ donation rates in a country like India. Methods: Here, we describe our experience with setting up a deceased donor program in a public sector hospital and its outcomes. Results: We harvested organs and tissues from 42 deceased donors between December 2013 and March 2020. The deceased donor program has helped in establishing a multi-organ transplantation program at our center, including liver and hand transplantation, in addition to kidney and corneal transplantation. Conclusion: Gathering a committed team of direct stakeholders with domain expertise, creating an organizational system, and establishing clear standard operating procedures (SOPs) are critical for success, in addition to physical infrastructure.


Renal transplantation in polycythemia vera:- A rare case report from India
Prashant Bharat Malviya, Sanjay Maitra

Indian Journal of Transplantation 2020 14(4):333-334

Polycythemia vera (PV) is a rare myeloproliferative neoplasm usually associated with JAK2 mutation. Manifestations include blood circulation disorder, hypertension and cerebral infarction. Renal disease is quite uncommon in PV and only few cases have been reported in the literature. In majority of these cases it was considered that PVinduced glomerular hyperperfusion and hyperfiltration as a cause of CKD. PV with ESRD and undergoing successful renal transplantation is much rarer. We here report one such patient of PV who had Budd Chiari syndrome, underwent hepatic vein stenting. He developed CKD which progressed to ESRD and underwent renal transplantation. To the best of our knowledge it is first case report from India.

Indian Journal of Transplantation 2020 14(4):335-337

A 16-year-old boy has been reported 3 months postcardiac transplantation with chief complaints of nausea, vomiting, pain in abdomen, and fever. The patient had remarkably increased serum lactate dehydrogenase levels, triglycerides, serum amylase, and serum lipase. The B-type natriuretic peptide level more than 35,000 ng/mL and troponin T was increased (0.57 μg/ml). Last known concentration of tacrolimus was 9 ng/ml. Supraventricular tachycardia was remarkable on electrocardiogram. His computed tomographic findings revealed bilateral pneumothorax with bilateral pleural effusion with an opacity seen in the right upper lobe. Bedside echo revealed dilated right atrium and right ventricle with left ventricular ejection fraction of 60%. He was kept on immunosuppression of mycophenolate mofetil 360 mg (2 tablets twice a day) and tacrolimus (2.5 mg twice a day). His reverse transcriptase-polymerase chain reaction throat swabs of the patient were sent for testing 2019-nCoV and were found to be negative. The patient could not be revived in spite of all medical management.
