RESUMO

AIM: In India, 85% of organ donations are from living donors and 15% are from deceased donors. One-third of living donors were rejected because of ABO or HLA incompatibility. Kidney exchange transplantation (KET) is a cost-effective and legal strategy to increase living donor kidney transplantation (LDKT) by 25%-35%. METHODS: We report our experience with 539 KET cases and the evolution of a single-centre program to increase the use of LDKT. RESULTS: Between January 2000 and 13 March, 2024, 1382 deceased donor kidney transplantations and 5346 LDKT were performed at our centre, including 10% (n = 539) from KET. Of the 539 KET, 80.9% (n = 436) were ABO incompatible pairs, 11.1% (n = 60) were compatible pairs, and 8% (n = 43) were sensitized pairs. There were 75% 2-way (n = 2 × 202 = 404), 16.2% 3-way (n = 3 × 29 = 87), 3% 4-way (n = 4 × 4 = 16), 1.8% 5-way (n = 5 × 2 = 10), 2.2% 6-way (n = 6 × 2 = 12), and 1.8% 10-way KET (n = 10 × 1 = 10). Of the recipients 81.2% (n = 438) were male and 18.8% (n = 101) were female, while of the donors, 78.5% (n = 423) were female and 21.5% (n = 116) were male. All donors were near relatives; wives (54%, n = 291) and mothers (20%, n = 108) were the most common donors. At a median follow-up of 8.2 years, patient survival, death censored graft survival, acute rejection, and median serum creatinine levels of functioning grafts were 81.63% (n = 440), 91% (n = 494), 9.8% (n = 53) and 1.3 mg/dL respectively. We credited the success to maintaining a registry of incompatible pairs, high-volume LDKT programs, non-anonymous allocation and teamwork. CONCLUSION: This is the largest single-centre KET program in Asia. We report the challenges and solutions to replicate our success in other KET programs.

RESUMO

BACKGROUND: There is a scarcity of data comparing the consequences of first and second COVID-19 waves on kidney transplant recipients (KTRs) in India. METHODS: We conducted a single-centre retrospective study of 259 KTRs with COVID-19 to compare first wave (March 15-December 31 2020, n = 157) and second wave (April 1-May 31 2021, n = 102). RESULTS: KTRs during second wave were younger (43 vs. 40 years; p-value .04) and also included paediatric patients (0 vs. 5.9%; p-value .003). Symptoms were milder during the second wave (45 vs. 62.7%; p-value .007); COVID-19 positive patients had less frequent cough (32 vs. 13.8%; p-value .001), fever was less frequent (58 vs. 37%; p-value .001), and we observed fewer co-morbidities (11 vs. 20.6%; p-value .04). The percentages of neutrophils (77 vs. 83%; p-value .001) and serum ferritin (439 vs. 688; p-value .0006) were higher during second wave, while lymphocyte counts were reduced (20 vs. 14%; p-value .0001). Hydroxychloroquine (11 vs. 0%; p-value .0001) and tocilizumab (7 vs. 0%; p-value .004) were more frequently prescribed during first wave, while utilization of dexamethasone (6 vs. 27%; p-value .0001) and remdesivir (47 vs. 65%; p-value .03) increased during the second wave. Mucormycosis (1.3 vs. 10%; p-value .01) and ICU admissions (20 vs. 37.2%; p-value .002) were more frequent during second wave. The 28-day mortality rate (9.6 vs. 10%; p-value 1) was not different. CONCLUSIONS: There has been a different clinical spectrum of COVID-19 amongst KTR with similar mortality between the two waves at a large Indian transplant centre.

RESUMO

Recent reports suggest that bridge-donor reneging is rare (1.5%) in non-simultaneous kidney exchange chains. However, in developing countries, the non-directed donors who would be needed to initiate chains are unavailable, and furthermore, limited surgical space and resources restrain the feasibility of simultaneous kidney exchange cycles. Therefore, the aim of this study was to evaluate the bridge-donor reneging rate during non-simultaneous kidney exchange cycles (NSKEC) in a prospective single-center cohort study (n = 67). We describe the protocol used to prepare co-registered donor-recipient pairs for non-simultaneous surgeries, in an effort to minimize the reneging rate. In addition, in order to protect any recipients who might be left vulnerable by this arrangement, we proposed the use of standard criteria deceased-donor kidneys to rectify the injustice in the event of any bridge-donor reneging. We report 17 successful NSKEC resulting in 67 living-donor kidney transplants (LDKT) using 23 bridge-donors without donor renege and no intervening pairs became unavailable. We propose that NSKEC could increase LDKT, especially for difficult-to-match sensitized pairs (25 of our 67 pairs) in countries with limited transplantation resources. Our study confirms that NSKEC can be safely performed with careful patient-donor selection and non-anonymous kidney exchanges.

RESUMO

BACKGROUND: To determine the knowledge, attitudes and practices regarding organ donation in western India. METHODS: Convenience sampling was used to generate a sample of 250; 200 interviews were successfully completed and used for analysis. Data collection was carried out via face to face interviews based on a pre-tested questionnaire in selected public areas of Ahmedabad, Gujarat state of India. Data entry was made in excel software in codes and analysis was done by SPSS software. RESULTS: About 86% of participants were aware of the term organ donation but knowledge about its various aspects was low. About 48% aware people heard about organ donation through medical fraternity, whereas only about 21% became aware through mass media. About 59% of aware people believed there is a potential danger of donated organs being misused, abused or misappropriated. About 47% of aware people said they would consider donating organs, while only 16% said they would definitely donate irrespective of circumstances. Around 97.67% participants said they would prefer to donate to nonsmokers. About 74.41% participants were unaware about any legislation regarding organ donation. About 77% participants showed their will to donate to mentally sound persons, and 42.04% participants showed their will to donate even physically challenged people. Around 78 participants felt that they would donate organs to persons irrespective of their religion. About 81% of aware people were of the opinion that consent for organ donation after death should be given by family members. None of the interviewed participants had a donor card. CONCLUSION: Better knowledge and awareness will help in promoting organ donation. Effective campaign needs to be driven to educate people with relevant information with the involvement of media, doctors and religious scholars.

RESUMO

Because access to transplantation with HLA-desensitization protocols and ABO incompatible transplantation is very limited due to high costs and increased risk of infections from more intense immunosuppression, kidney paired donation (KPD) promises hope to a growing number of end-stage renal disease (ESRD) patient in India. We present a government and institutional ethical review board approved study of 56 ESRD patients [25 two-way and 2 three-way pairs] who consented to participate in KPD transplantation at our center in 2013, performed to avoid blood group incompatibility (n = 52) or positive cross-match (n = 4). All patients had anatomic, functional, and immunologically comparable donors. The waiting time in KPD was short as compared to deceased donor transplantation. Laparoscopic donor nephrectomy was performed in 54 donors. Donor relationships were spousal (n = 40), parental (n = 13), others (n = 3), with median HLA match of 1. Graft survival was 97.5%. Three patients died with functioning graft. 16% had biopsy-proven acute rejection. Mean serum creatinine was 1.2 mg/dl at 0.73 ± 0.32 months follow-up. KPD is a viable, legal, and rapidly growing modality for facilitating LDRT for patients who are incompatible with their healthy, willing living donor. To our knowledge, this is the largest single-center report from India.

RESUMO

According to the Indian chronic kidney disease registry, in 2010 only 2% of end stage kidney disease patients were managed with kidney transplantation, 37% were managed with dialysis and 61% were treated conservatively without renal replacement therapy. In countries like India, where a well-organized deceased donor kidney transplantation program is not available, living donor kidney transplantation is the major source of organs for kidney transplantation. The most common reason to decline a donor for directed living donation is ABO incompatibility, which eliminates up to one third of the potential living donor pool. Because access to transplantation with human leukocyte antigen (HLA)-desensitization protocols and ABO incompatible transplantation is very limited due to high costs and increased risk of infections from more intense immunosuppression, kidney paired donation (KPD) promises hope to a growing number of end stage kidney disease patients. KPD is a rapidly growing and cost-effective living donor kidney transplantation strategy for patients who are incompatible with their healthy, willing living donor. In principle, KPD is feasible for any centre that performs living donor kidney transplantation. In transplant centres with a large living donor kidney transplantation program KPD does not require extra infrastructure, decreases waiting time, avoids transplant tourism and prevents commercial trafficking. Although KPD is still underutilized in India, it has been performed more frequently in recent times. To substantially increase donor pool and transplant rates, transplant centres should work together towards a national KPD program and frame a uniform acceptable allocation policy.

RESUMO

OBJECTIVES: To evaluate whether the outcomes of renal grafts from living related donors older than 60 years are acceptable, in terms of renal function and patient/graft survival. MATERIAL AND METHODS: One hundred and forty-seven patients who received kidneys from donor age ≥60 years constituted the study group (group 1). The control group (group 2) consisted of 1310 patients who received renal transplants from donor age <60 years. Outcome measures included graft, patient survival, acute rejection rate and serum creatinine (SCr) in patients/donors. Graft and patient survivals were compared using the Kaplan-Meier method. RESULTS: The mean age of donors was 62.7 ± 3.39 years in group 1 and 43.45 ± 9.65 years in group 2. Patient survival at 1, 3 and 5 years was 95.7%, 89.4% and 82.6% in group 1 and 93.8%, 89.1% and 83.1% in group 2 (p = 0.785), respectively. Death-censored graft survival at 1, 3 and 5 years was 98.5%, 94.8% and 94.8% in group 1 and 96.1%, 92.9% and 89% in group 2 (p = 0.166), respectively. Biopsy-proven acute rejections were 21% and 16.8% (p = 0.206) and chronic rejections 5% and 3.4% in group 1 and 2, respectively (p = 0.542). Recipient SCr (mg/dL) was 1.8 ± 0.31 in group 1 and 1.58 ± 0.37 in group 2. The donor SCr levels at the last follow-up were 1 mg/dL and 0.9 mg/dL in group 1 and 2, respectively. CONCLUSIONS: Donor age did not affect patient and graft survival in the 5-year follow-up in our study. Age alone seems not to be an exclusion criterion to living kidney donation.

RESUMO

BACKGROUND: Kidney paired donation (KPD) is a rapidly growing modality for facilitating living donor kidney transplantation (LDKTx) for patients who are incompatible with their healthy, willing and living donor. The impact of donor-recipient age difference on long and short-term graft and patient survivals in LDKTx is still uncertain. METHODS: A total of 1502 LDKTx recipients who received regular follow-up in our center from 1999 to 2012 were studied. Donor-recipient age difference was divided into subgroups (donor-recipient 0-10, 11-20, 0-20, 21-30, 31-40, and 21-40 years). Outcome measures included death censored graft, patient survival and acute rejection rate. RESULTS: The 1-, 5-, 10-year patient survival of the donor-recipient age difference ≤20 years group showed no difference compared with the age difference >20 years group (94.5%, 83.2%, 71.9% and 95.2%, 86%, 77.8%, p = 0.053). The 1-, 5-, 10-year graft survival of the donor-recipient age difference ≤20 years group showed no difference compared with the age difference >20 years group (94.6%, 81.6%, 72.1% and 94%, 80%, 72.2%, p = 0.989). The rejection were also similar (17.5% vs. 16.5%, p > 0.05). There was no statistically significant difference in graft survival and acute rejection rate in all subgroups. CONCLUSIONS: Older donors (usually within families) are not associated with worse outcome is reassuring. KPD should not be prohibited due to high donor-recipient age difference, when size of donor pool is small as in single center KPD program.

RESUMO

Despite heightened international interest in performing living donor kidney paired donation (KPD) transplantation after the publication of a research protocol by Ross and colleagues in 1997, only a few hundred have been performed worldwide. The major obstacle is that many individuals in end-stage renal disease are of blood type O and can only receive an organ from a donor of blood type O, whereas blood type O donors are "universal donors" and will be able to donate directly with an intended recipient of any blood type unless there is a positive crossmatch. To overcome this, patients with compatible but non-HLA identical donors over 45 years of age should be approached for inclusion in KPD program especially O blood group donors. Inclusion of all these additional pairs into the algorithm greatly increases chances of possible matches for O blood group recipients. We report successful three-way KPD transplantation resulting in transplantation of O blood group patient using compatible O blood group donor from India. None of the patients had delayed graft function or rejection and all had stable graft function on discharge without any medical and surgical complications. We need to allocate O blood group kidneys from compatible donors to overcome the barrier of HLA, non-HLA antibodies and other donor related factors to improve transplant quality and long term outcomes. This will increase transplantation of O blood group patients.

RESUMO

BACKGROUND: Chronic heart failure (CHF) and chronic kidney disease (CKD) are serious medical conditions with significant morbidity and mortality and often coexist. Because of perioperative risks in these patients, they may not be considered a candidate for renal transplantation (RTx). MATERIAL AND METHODS: We compare retrospectively RTx outcomes [graft/patient survival, rejection rates and adverse cardiac events] in study group [low left ventricular ejection fraction (LVEF) ≤ 45% by echocardiogram, n = 63] and control group [normal LVEF ≥ 50%, n = 537] from a developing country. RESULTS: The mean EF was 35 ± 5.6 and 57 ± 3% for the study and control groups, respectively (p < 0.001). Majority of these patients (98%) showed normalization of LVEF post-transplant. The median EF was 60% at 1-3 months post-transplant. No difference was noted in graft survival, patient survival, rejection rates, serum creatinine and adverse cardiac events of study group at 1.3-year mean follow-up compared to control group. Outcome was not adversely affected by preexisting LV dysfunction. The study and control groups had nearly similar percent of patients with established CAD but significantly more hospitalization for CHF pre RTx in the study group compared with the control group. CONCLUSION: RTx may play a role in reversing LV systolic dysfunction. Once thought by many to be a contraindication for renal transplantation, this appears not to be the case. The outcomes between the 2 groups are comparable and transplant is an option for even low EF patients.

RESUMO

BACKGROUND: In India, there are a large number of end-stage renal disease (ESRD) patients waiting for renal transplantation (RT). Organ retrieval from brain dead deceased donor (DD) is getting increased attention as the waiting list for organ recipients far exceeds the organ donor pool. In our country, despite a large population, the number of brain dead donors undergoing organ donation is very less. DDRT is the possible solution to bridge the disparity between organ supply and demand. In India, the potential for DDRT is huge due to the high number of fatal road traffic accidents and this pool is yet to be tapped. PATIENTS AND METHODS: We report DDRT outcome in 294 patients (age: 36.5 ± 14.1 years; male:female, 200:94) between 2005 and 2012. All patients received single-dose rabbit-anti-thymocyte globulin for induction and steroids, calcineurin inhibitor, and mycophenolate mofetil/azathioprine for maintenance immunosuppression. RESULTS: Our retrospective study in 294 DDRT shows a fairly successful outcome. Over a mean follow-up of 3.93 years, patient and graft survival rates were 81.7% and 92.6%, respectively, with a median serum creatinine of 1.5 mg/dL. 20.7% had biopsy-proven acute rejection. CONCLUSION: Given the widespread organ shortage, DDRT has a potential to expand the donor pool and shorten the waiting list for RT, encouraging the use of this approach even in low-income countries. Aggressive donor management, increasing public awareness about the concept of organ donation, good communication between clinician and the family members, and a well-trained team of transplant coordinators can help in improving the number of organ donations.

RESUMO

BACKGROUND: Kidney paired donation (KPD) is feasible for any center that performs living related donor renal transplantation (LRDRTx). Lack of awareness, counseling and participation are important hurdles in KPD patients with incompatible donors. MATERIALS AND METHODS: This is an institutional review board approved study of 10 ESRD patients who consented to participate in the KPD transplantation at our center. All the surgeries were carried out on the same day at the same center on the occasion of World Kidney Day (WKD) (14 March 2013). All recipients had anatomic, functional and immunological similar donors. RESULTS: KPD were performed to avoid blood group incompatibility (n = 8) or to avoid a positive crossmatch (n = 2). None of the patients experienced delayed graft function and surgical complications. At 3 month follow-up, median serum creatinine was 1 (range 0.6 to 1.25) mg/dL and two patients developed allograft biopsy-proven acute rejection and responded to antirejection therapy. Due to impact of our awareness activity, 20 more KPD patients are medically fit for transplantation and waiting for permission from the authorization committee before transplantation. CONCLUSION: This is a report of 10 simultaneous KPD transplantations in a single day in a single centre on WKD raising awareness of KPD. KPD is viable, legal and rapidly growing modality for facilitating LRDRTx for patients who are incompatible with their healthy, willing LRD.

RESUMO

BACKGROUND: Kidney Paired Donation (KPD) is a rapidly growing modality for facilitating living related donor kidney transplantation (LRDKTx) for patients who are incompatible with their healthy, willing, and living donors. Data scarcity on the outcome of KPD versus LRDKTx prompted us to review our experience. MATERIALS AND METHODS: This was a single-center study of 224 patients on regular follow-up, who underwent LRDRTx from January 2010 to June 2012 at our institute. The aim of this study was to compare short-term graft survival, patient survival and rejection rates of KPD (group 1, n = 34) with those of LRDKTx (group 2, n = 190). All the recipients received triple immunosuppression and thymoglobulin induction in KPD group. Kaplan-Meier curves were used for survival analysis. In group 1, mean recipient age was 35.5 ± 13.2 years, 29 were men and mean donor age was 44.4 ± 8.17 years, 10 were men. In group 2, mean recipient age was 29.1 ± 10 years, 155 were men and mean donor age was 47.5 ± 9.69 years, 74 were men. Mean human leukocyte antigen (HLA) matching in group 1 and 2 was 1 versus 3.2 (p < 0.05). RESULTS: One- and two-year patient survival showed no significant difference between the two groups (97.1%, 97.1% vs. 96.2%, 94.8%, respectively, p = 0.81). Death-censored graft survival also showed no significant difference between the two groups (97.1%, 97.1%, vs. 97.6%, 97.6%, p = 0.73). Acute rejection incidence was also similar (8.7% vs. 9.9%, p > 0.62). CONCLUSIONS: Our study showed similar graft survival, patient survival and rejection rates of KPD versus LRDKTx over 2 years post-transplantation, encouraging the use of this approach for national KPD program.

RESUMO

Down syndrome is one of the most common genetic causes of learning disabilities in children. Although the incidence of renal and urological involvement in Down syndrome is not very common, monitoring of patients with Down syndrome for renal diseases should be done regularly as patient's age into the second and third decades. With increased survival, it appears that a growing number of these patients present with chronic renal failure. Down syndrome patients are apparently not suited for peritoneal dialysis because of lacking cooperation. This procedure can be prone to failure, mainly because of an increased risk of peritonitis. Handling such patients especially those on peritoneal dialysis is challenging. Here we report a case of Down syndrome with end-stage renal disease treated with hemodialysis for 6 months. To the best of our knowledge and current literature review this is the first case report of a patient with Down syndrome undergoing hemodialysis.

RESUMO

OBJECTIVES: There are scarce data on the incidence and resistance pattern of rifampicin-resistant Mycobacterium tuberculosis among kidney transplant recipients. MATERIALS AND METHODS: This is a retrospective, single- center study of kidney transplantrecipients suspected of M. tuberculosis infection. The GeneXpert assay we used detected mutations in the rpoB gene that confer rifampicin resistance using 5 overlapping probes (A, B, C, D, and E). The probes can detect mutations in the codons 507 to 511 (probe A), 511 to 518 (probe B), 518 to 523 (probe C), 523 to 529 (probe D), and 529 to 533 (probe E).We also detailed the treatment protocol and outcomes of kidney transplantrecipients infected with rifampicin-resistant M. tuberculosis. RESULTS: In total, 2700 samples were processed during the period from October 2018 to February 2022 with successful results in 2640 samples (97.04%). One hundred and ninety (7.19%) samples were positive for M.tuberculosis, and rifampicin resistance was detected in 12 (0.45%) cases (11 pulmonary, 1 genitourinary). The most common rpoB mutation was located in the region of probe E (75.0%), followed by probe A (16.6%) and in 1 combination probe DE (8.33%). The rpoB mutations were not observed in probe B and probe C. Six patients received bedaquiline-based treatmentfor a short course of 11 months, whereas the other 6 patients required a long course of 18 to 20 months. Three patients died, 2 were lost to follow-up, and 7 were cured. During treatment, 4 patients experienced acute rejection, and 1 graft loss was reported. CONCLUSIONS: We report for the first time the incidence and pattern of rifampicin resistance among kidney transplant recipients with tuberculosis infection. Further investigations are required for exploring the molecular and clinical phenotypes.

RESUMO

Introduction: Chronic kidney disease patients on hemodialysis (CKD-5D) are among the worst hit by the coronavirus disease 2019 (COVID-19) pandemic. Need to travel for dialysis, comorbidities, and immunosuppressive state put them at risk of severe disease and poor outcomes. We report our experience of COVID-19 in a cohort of CKD-5D from a public sector tertiary-care center from western India. Material and Methods: We retrospectively analyzed the records of 58 CKD-5D patients with confirmed COVID-19 admitted to our COVID-19 hospital. Suspected COVID-19, acute kidney injury (AKI), or AKI on CKD were excluded. We studied the clinical, demographic, radiological, and laboratory profiles; treatment; and outcomes of the patients. We assessed the potential clinical and laboratory parameters to predict mortality. Results: The mean age of the patients was 48.7 ± 16.9 years, with 55% males. Comorbidities included hypertension (65%), diabetes (19%), and cardiovascular disease (15.5%). The presenting features included fever (69%), respiratory distress (50%), upper respiratory symptoms (36%), and diarrhea (13%). Five (8.6%) were asymptomatic. Bilateral infiltrates on chest imaging were the commonest radiological pattern. The patients were managed with oxygenation, hydroxychloroquine, steroids, anticoagulation, remdesivir, and favipiravir. Twenty-two (37.9%) patients died, predominantly due to respiratory failure. Disease severity and C-reactive protein (CRP) above 175 mg/L at admission were the only parameters predictive of mortality. Conclusion: CKD-5D patients with COVID-19 were less likely to present with the classical syndrome of fever and respiratory distress compared with reports from the general population and had higher mortality. Only disease severity and high CRP (>175 mg/L) were predictive of mortality in our cohort.

RESUMO

Coronavirus disease (COVID-19) has engulfed the whole world, and India has been the second worst-hit nation. Organ transplant services were halted in both the public and private care sectors of India, with public care sectors more adversely affected. Deceased donations were disproportionately more affected, with unfavorable rates at the peak of the pandemic. Mortality outcomes of COVID-19 among different organ transplant recipients in India have been lower compared with the Western world, with younger age and less comorbidities among Indian populations partly responsible for the lower mortality. Mortality and graft loss were mostly associated with older age and those with chronic graft dysfunction. During the pandemic, invasive fungal infections, like mucormycosis, have been reported, illustrating the need for multidisciplinary management. The Indian transplant societies have formulated and timely revised guidelines for transplantation in the COVID-19 era. Living donor transplants (both liver and kidney) after recovery from COVID-19 were both first described in India, providing a guiding tool for the world. Follow-up reports of recovered solid-organ transplant recipients have also been reported in Indian studies, showing reassuring long-term outcomes. Data of breakthrough COVID-19 cases after vaccination among both transplant recipients and waitlist candidates and research in vaccine efficacy for solid-organ transplant recipients is still underway. We suggest continuing and intensifying research activities for a better plan and strategy in case of a future pandemic.

RESUMO

INTRODUCTION: Tunneled cuffed catheters (TCC) provides a short and intermediate-term access solution for dialysis patients who fail to get an arteriovenous fistula (AVF). They are associated with high morbidity and mortality along with high rates of infectious complications. METHODS: We present a single-center prospective cohort of 159 TCCs inserted over one year. Patients were dialyzed in-hospital and in various peripheral dialysis units attached to the institute. The primary endpoint was catheter drop-out. RESULTS: The mean age of patients was 41.8 ± 16.9 years. The right internal jugular vein was the commonest site of TCC insertion (66%). The absence of suitable veins was the predominant reason for TCC insertion. The mean time to catheter drop-out was 134.4 ± 83.3 days (5-399 days). Death with a working catheter was the most common cause of catheter drop-out (22.6%). About 25% of catheters were lost to catheter-related bloodstream infections (CRBSI), either alone or as overlap with poor flow. CRBSI rates were 3.74 episodes per 1000 catheter-days. No difference in survival between the staggered tip and split-tip catheters was found. CONCLUSIONS: With the advent of the "hub and spoke" model for dialysis in the public sector healthcare, TCCs are suboptimal with regards to patient and catheter survival, with high infection rates. It must be regarded as a temporary solution and AVF creation should be prioritized.

RESUMO

OBJECTIVES: Data are so far limited on outcomes of kidney transplant recipients with COVID-19 seen at public sector hospitals in developing countries with limited resources. MATERIALS AND METHODS: We retrospectively investigated a cohort of 157 kidney transplant recipients (75% living and 25% deceased donors) seen at a public sector transplant hospital in India from March to December 2020 who had reverse-transcriptase polymerase chain reaction tests that confirmed COVID-19. Demographic data, immunosuppression regimens, clinical profiles, treatments, and outcomes were analyzed. In our center, maintenance immunosuppression was reduced according to disease severity and case-by-case evaluations. There were also 53 patients with asymptomatic or mild COVID-19 symptoms who received home care to optimize the utilization of scarce resources during travel restrictions. RESULTS: In our kidney transplant recipient group, median age was 43 years (133 male; 24 female patients); recipients presented at a median of 4 years after transplant. The most common comorbidities included arterial hypertension (73%) and diabetes (24%); presenting symptoms at the time of COVID-19 positivity included cough (49%), fever (58%), and sputum production (32%). Clinical severity ranged from asymptomatic (4%), mild (45%), moderate (31%), and severe (20%) disease. Statistically significant risk factors for mortality included older age, dyspnea, severe disease, obesity, allograft dysfunction prior to COVID-19, acute kidney injury, higher levels of inflammatory markers (C-reactive protein, interleukin 6, procalcitonin), abnormality in chest radiography, and intensive care/ventilator requirements (P < .05). Overall patient mortality was 9.5% (15/157) in hospitalized patients, 21% (15/71) in patients in the intensive care unit, 100% (15/15) in patients who required ventilation, and 0% among those in home treatment. CONCLUSIONS: The mortality rate in kidney transplant recipients with COVID-19 was higher than in the nonimmunosuppressed general population (1.2%) in India. To our knowledge, this is a largest single-center study of kidney transplant recipients with COVID-19 so far.
