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

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

OBJECTIVES: COVID-19 has emerged as a global pandemic with significant impacts on health care systems. The present study was conducted to analyze the effects of the COVID-19 pandemic on nephrology and transplant services and clinical training at our center. MATERIALS AND METHODS: This observational study was conducted at the Institute of Kidney Disease and Research Centre (Ahmedabad, India). Our institute is one of the largest tertiary care centers of its kind in India with around 400 total inpatient beds for nephrology, urology, and transplant patients. In 2019, our center had annual outpatient and inpatient numbers of 132 181 and 7471, respectively, and conducted 412 renal transplant procedures. For this study, monthly data on number of outpatients, inpatients, and patients undergoing renal transplant, as well as various nonelective procedures, conducted in 2019 and 2020 were collected and analyzed. We investigated the impact of the COVID-19 pandemic on various non-COVID-19-related health care facilities and on clinical training and research activities at our institute. RESULTS: During the 2020 COVID-19 period, the number of outpatients and inpatients was greatly reduced compared with data from 2019. A similar decrease was seen in patients undergoing hemodialysis, renal transplant, and nonelective procedures at our center. The COVID-19 period also greatly affected clinical training of residents enrolled at our institute and research activities, as a result of focus on COVID-19 as a priority. CONCLUSIONS: The effects of reduced numbers of outpatients and inpatients on workflow, as well as reduced numbers of renal transplants and nonelective procedures on the health of our patients, are unknown. Hence, a strategic scheme is needed to develop new health care models that can help manage the COVID-19 pandemic at present and any further waves arising in the future.

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

OBJECTIVES: There are limited clinical data on feasibility and safety of convalescent plasma therapy in kidney transplant recipients with severe COVID-19. The present study was conducted to explore the feasibility of convalescent plasma treatment in 10 kidney transplant recipients with severe COVID-19. MATERIALS AND METHODS: The prospective observational cohort study was conducted at the Institute of Kidney Disease and Research Centre, Ahmedabad, India. All patients were admitted to the intensive care unit and received antiviral therapy, glucocorticoids, and other supportive care. Two doses of 200 mL each of convalescent plasma with neutralization activity of >1:640 were transfused into patients 24 hours apart following the World Health Organization blood transfusion protocol. The endpoints were the improvement of clinical symptoms and laboratory parameters within 1 day and 7 days after convalescent plasma transfusion. RESULTS: The patients showed resolution of clinical symptoms, and there was a significant decrease in inflammatory markers (P < .05) within 7 days of convalescent plasma transfusion. Of the 10 patients, 9 patients had full recovery and 1 patient died. CONCLUSIONS: Convalescent plasma therapy is highly safe and clinically feasible and reduces mortality in kidney transplant recipients with severe COVID-19. Larger clinical registries and randomized clinical trials should be conducted to further explore the clinical outcomes associated with convalescent plasma use in kidney transplant recipients with severe COVID-19.

RESUMO

BACKGROUND: There is a scarcity of data on the consequences of coronavirus disease-19 (COVID-19) infections in kidney transplant recipients (KTRs) from emerging countries. METHODS: Here, we present a cohort study of 13 transplant centers in India including 250 KTR (226 living and 24 deceased donors) with polymerase chain reaction-confirmed COVID-19 positivity from March 23, 2020, until September 15, 2020. We detailed demographics, immunosuppression regimen, clinical profile, treatment, and outcomes. RESULTS: Median age of transplant recipients was 43 years, and recipients presented at a median of 3.5 years after transplant. Most common comorbidities (94%) included arterial hypertension (84%) and diabetes (32%); presenting symptoms at the time of COVID-19 included fever (88%), cough (72%), and sputum production (52%). Clinical severity ranged from asymptomatic (6%), mild (60%), and moderate (20%) to severe (14%). Strategies to modify immunosuppressants included discontinuation of antimetabolites without changes in calcineurin inhibitors and steroids (60%). Risk factors for mortality included older age; dyspnea; severe disease; obesity; allograft dysfunction before COVID-19 infection; acute kidney injury; higher levels of inflammatory markers including C-reactive protein, interleukin-6 level, and procalcitonin; chest X-ray abnormality, and intensive care unit/ventilator requirements. Overall patient mortality was 11.6% (29 of 250), 14.5% (29 of 200) in hospitalized patients, 47% (25 of 53) in intensive care unit patients, and 96.7% (29 of 30) in patients requiring ventilation. KTRs with mild COVID-19 symptoms (n = 50) were managed as outpatients to optimize the utilization of scarce resources during the COVID-19 pandemic. CONCLUSIONS: Mortality rates in COVID-19-positive KTR appear to be higher than those in nonimmunosuppressed patients, and high mortality was noted among those requiring intensive care and those on ventilator.

RESUMO

OBJECTIVES: Gujarat, Tamil Nadu, Telangana, Maharashtra, Kerala, Chandigarh, and Karnataka are states in India with active programs for deceased donor kidney transplant. We report our experience of 2 decades of deceased donor kidney transplant at the Institute of Kidney Diseases and Research Center, Dr. H. L. Trivedi Institute of Transplantation Sciences, Ahmedabad, Gujarat, India. MATERIALS AND METHODS: This single-center retrospective study comprised data from 831 deceased donor kidney transplant recipients between January 1, 1997 and December 31, 2018. Mean recipient age was 38 ± 14 years; 564 were male, and 267 were female. Mean donor age was 45.3 ± 17.13 years; 565 were men, and 266 were women. RESULTS: Between January 1, 1997 and March 15, 2020, 5838 kidney transplants were completed, including 4895 living donor kidney transplants, 943 deceased donor kidney transplants, and 440 kidney paired donation transplants. Over the mean follow-up time of 8 ± 5.4 years, patient survival rate was 70% (n = 581) and death-censored graft survival rate was 84% (n = 698). Delayed graft function was shown in 210 patients (25%) and biopsy-proven acute rejection rate in 180 patients (21%). Our experience of favorable outcomes with deceased donor kidney transplants has expanded the donor pool in many ways, including transplant from expanded criteria donors to younger recipients; transplant from older donors to older recipients; donation after cardiac death; successful intercity organ procurement; dual-kidney transplant; en bloc transplant from a pediatric deceased donor; and transplant from brain death deceased donors who died from neurotoxic snakebite, recurrent primary brain tumor, bacterial meningitis, or head injury, or with disseminated intravascular coagulation and deranged renal functions. The pathway to increase organ donation was investigated. CONCLUSIONS: Deceased donor kidney transplant can achieve acceptable graft function with patient/graft survival, which may encourage the use of this approach to increase the number of available organs.

RESUMO

The kidney is the most common organ involved in systemic amyloidosis. We aimed to study etiology and clinicopathological profile of renal amyloidosis. This was a retrospective study of 40 consecutive adult patients with biopsy-proven renal amyloidosis evaluated over a period of two years. Emphasis was given to describing the clinical presentation, renal function, proteinuria, type of amyloidosis, and its etiology. Mean age of the study cohort was 44 ± 15 years (with a male-to-female ratio of 3:1). Amyloid A (AA) amyloidosis was the most common type of amyloidosis observed in 72.5% of cases. Amyloid light chain (AL) amyloidosis accounted for 17.5% of cases, and the rest remained undetermined. AA amyloidosis had widespread age distribution while AL amyloidosis was confined to those >40 years. Proteinuria was the most common renal manifestation observed in all patients. Nephrotic syndrome was seen in 70% of patients. Mean 24 h proteinuria was 6.4 g. Renal failure was the second most common manifestation seen in 70% of patients, of whom 21.4% required hemodialysis. Tuberculosis (TB) accounted for 90% cases of AA amyloidosis. The most prevalent form was pulmonary TB while the rest accounted for by rheumatoid arthritis and bronchiectasis. Among patients with TB induced amyloidosis, 61.5% had received adequate treatment for TB in the past. All patients with AL amyloidosis had nephrotic range proteinuria, five had renal failure out of which two required dialysis. Cardiac involvement was seen in two patients. AA amyloidosis was the most common type of renal amyloidosis in the present study and pulmonary TB was the most common etiology.

RESUMO

Epstein syndrome constitutes macrothrombocytopenia without neutrophil inclusion bodies along with deafness and renal failure. A diagnosis of Epstein syndrome was made in a 17 year-old-male patient with macrothrombopathic thrombocytopenia, renal failure and sensorineural hearing loss. Our patient is unique as he presented with rapidly progressive renal failure and developed chronic kidney disease in second decade of life with no symptomatic hearing loss or bleeding tendency. Epstein syndrome needs to be differentiated from Alport syndrome which is more common disease with similar clinical presentation.

RESUMO

Introduction: The kidneys are involved in significant number of patients with multiple myeloma (MM) who can present with acute or chronic renal failure, nephritic syndrome, non-nephrotic proteinuria or tubular function defects. Objectives: To assess the clinical profile of kidney involvement preceding diagnosis of multiple myeloma Patients and Methods: Renal involvement in 29 cases with MM admitted over an 18-month period to our tertiary care center was retrospectively examined. Diagnosis of MM was confirmed by two or more of the following four features: lytic bone lesions, serum or urine monoclonal peak, Bence-Jones proteinuria, and greater than 20% plasma cells in bone marrow. Results: Renal disease was present in all patients before MM was diagnosed. Non-steroidal anti-inflammatory drugs (NSAIDs) was the most common precipitating factor for acute kidney injury (AKI). All 29 patients received combination chemotherapy of bortezomib, dexamethasone and thalidomide. More than half of the total number of patients did not complete chemotherapy because of death or lost to follow-up. Twenty-two of 29 patients required hemodialysis support. AKI was the most common renal presentation of MM. Four patients with AKI had complete renal recovery. Eleven patients who required hemodialysis support initially later on recovered to non-dialyzable range of renal failure. Seven patients became hemodialysis dependent. Twelve patients died from infection, uremia or hyperkalemia. Nine patients lost to follow up. Remission of MM was seen in 8 patients who completed chemotherapy. Conclusion: In our study AKI is the most common renal presentation preceding the diagnosis of MM. Reversal of renal function was achieved with chemotherapy and high flux hemodialysis in few cases.

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

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

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

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

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

We conducted a single-center prospective double-arm open-labeled study on kidney transplant patients from 2010 to 2011 to evaluate the efficacy of induction therapy using low, single-dose rabbit-antithymocyte globulin (r-ATG), 1.5 mg/kg on Day 0 (n = 80, 60 males, mean age 35.9 years), versus basiliximab (Interleukin-2 blocker) 20 mg on Days 0 and 4 (n = 20, 12 males, mean age 45.1 years) on renal allograft function in terms of serum creatinine (SCr), rejection and infection episodes and patient/graft survival and cost. Demographic and post-transplant follow-up including immunosuppression was similar in both groups. In the r-ATG group, donors were unrelated (spouse, n = 25), deceased (n = 31) and parents/siblings (others), with a mean HLA match of 1.58. Donors in the basiliximab group were living unrelated (spouse, n = 15) and deceased (n = 5), with a mean HLA match of 1.56. No patient/graft was lost in the r-ATG group over a mean of one year follow-up, and the mean SCr was 1.28 mg/dL with 7.5% acute rejection (AR) episodes; infections were also not observed. In the basiliximab group, over the same period of follow-up, there was 95% death-censored graft survival, and the mean SCr was 1.23 mg/dL with 10% AR episodes. One patient died due to bacterial pneumonia and one succumbed to coronary artery disease; one graft was lost due to uncontrolled acute humoral and cellular rejection. The cost of r-ATG and basiliximab were $600 and $2500, respectively. We conclude that induction immunosuppressive therapy with a low-dose r-ATG may be a better option as compared with basiliximab in terms of graft function, survival and cost benefit in kidney transplant 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: 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.
