Background There is limited current knowledge on feasibility and safety of kidney transplantation in COVID-19 survivors. Methods We present a retrospective cohort study of 75 kidney transplants in patients who recovered from polymerase chain reaction (PCR) confirmed COVID-19 performed across 22 transplant centers in India from July 3, 2020 to January 31, 2021. We detail demographics, clinical manifestations, immunosuppression regimen, laboratory findings, treatment and outcomes. Patients with a previous diagnosis of COVID-19 were accepted after documenting 2 negative SARS-CoV-2 PCR tests, normal chest imaging with complete resolution of symptom for at least 28 days and significant social distancing for 14 days prior to surgery. Results Clinical severity in patients ranged from asymptomatic (n=17, 22.7%), mild(n=36,48%), moderate(n=15,20%) and severe(n=7,9.3%) disease. Median duration between PCR positive to transplant was 60 days (overall) and, increased significantly from asymptomatic, mild, moderate and severe disease (49,57,83,94 days, P-value 0.019) respectively. All recipients and donors were asymptomatic with normal creatinine after surgery at a median (interquartile range) follow up of 81 (56-117) days without any complications relating to surgery or COVID-19. Patient and graft survival was 100%, and acute rejection was reported in 6.6%. Conclusions Prospective kidney transplant recipients post-COVID-19 can be considered for transplantation after comprehensive donor and recipient screening before surgery using a combination of clinical, radiologic, and laboratory criteria, careful pre-transplant evaluation, and individualized risk-benefit analysis. Further large-scale prospective studies with longer follow-up will better clarify our initial findings. Till date, this remains the first largest study of kidney transplantation in COVID-19 survivors.Supplemental Visual Abstract; http://links.lww.com/TP/C180.

Background To ascertain the validity of kidney paired donations (KPDs) as an alternative strategy for increasing living donor kidney transplantations (LDKTs) in an LDKT-dominated transplant programme since directed kidney transplantation, ABO-incompatible or crossmatch-positive pairs are not feasible due to costs and infectious complications. Methods This was a prospective single-centre study of 77 KPD transplantations (25 two-way, 7 three-way and 1 six-way exchange) from 1 January 2015 to 1 January 2016 of 158 registered donor recipient pairs. During this period, a total of 380 kidney transplantations [71 deceased donor kidney transplantations (DDKTs), 309 LDKTs] were performed. The reasons for opting for KPD were ABO incompatibility (n = 45), sensitization (n = 26) and better matching (n = 6). Results KPD matching was facilitated in 62% (n = 98) of transplants. In all, 48.7% (n = 77) of the transplants were completed in 2015, whereas 13.3% (n = 21) of the matched patients were to undergo transplant surgery in early 2016 after getting legal permission. The waiting time for KPD was shorter compared with DDKT. The death-censored graft survival and patient survival were 98.7% (n = 76) and 93.5% (n = 72), respectively. In all, 14.2% (n = 11) of patients had acute rejection. Match rates among sensitized (n = 60) and O group patients (n = 62) were 58.3% (n = 35) and 41.9% (n = 26), respectively. Of these, 43.3% (n = 26) and 29% (n = 18) of transplants were completed and 15% (n = 9) and 12.9% (n = 8), respectively, are waiting for legal permission. Conclusions LDKT increased by 25% in 1 year in our single-centre KPD programme. Our key to success was the formation of a KPD registry, awareness and active counselling programs and developing a dedicated team.

One third of healthy willing living kidney donors are rejected due to ABO blood group incompatibility and donor specific antibody. This increases pre-transplant dialysis duration leading to increased morbidity and mortality on the kidney transplantation waiting list. Over the last decade kidney paired donation is most rapidly increased source of living kidney donors. In a kidney transplantation program dominated by living donor kidney transplantation, kidney paired donation is a legal and valid alternative strategy to increase living donor kidney transplantation. This is more useful in countries with limited resources where ABO incompatible kidney transplantation or desensitization protocol is not feasible because of costs/infectious complications and deceased donor kidney transplantation is in initial stages. The matching allocation, ABO blood type imbalance, reciprocity, simultaneity, geography were the limitation for the expansion of kidney paired donation. Here we describe different successful ways to increase living donor kidney transplantation through kidney paired donation. Compatible pairs, domino chain, combination of kidney paired donation with desensitization or ABO incompatible transplantation, international kidney paired donation, non-simultaneous, extended, altruistic donor chain and list exchange are different ways to expand the donor pool. In absence of national kidney paired donation program, a dedicated kidney paired donation team will increase access to living donor kidney transplantation in individual centres with team work. Use of social networking sites to expand donor pool, HLA based national kidney paired donation program will increase quality and quantity of kidney paired donation transplantation. Transplant centres should remove the barriers to a broader implementation of multicentre, national kidney paired donation program to further optimize potential of kidney paired donation to increase transplantation of O group and sensitized patients. This review assists in the development of similar programs in other developing countries.

C1q nephropathy is a rare glomerular disease defined by the presence of characteristic mesangial dominant or codominant C1q deposition on immunofluorescence microscopy. Neurofibromatosis type 1 (NF-1) is an autosomal dominant syndrome caused by a mutation of a gene located on chromosomal segment 17q11.2. Nephrotic syndrome has rarely been reported in patients of NF-1, and the relation of NF-1 with nephrotic syndrome is unclear. Here, we present a rare case of C1q nephropathy in a patient of NF-1.

The best and most cost-effective treatment for end-stage renal disease patients is living donor (LD) renal transplantation. It has survival benefit compared to deceased donor (DD) kidney transplant (DDKT) and long-term dialysis and provides a better quality of life. Efficient and effective kidney allocation methods are increasingly necessary to address the problem of organ scarcity. The use of kidney paired donation transplant has increased access to LD kidney transplantation (LDKT) with outstanding results. ABO-incompatible kidney transplantation (KT) and desensitization protocol can expand the donor pool, but as integral to any aggressive immunosuppression protocol, they are associated with increased risk of infection and malignancy. Given the widespread organ shortage, DDKT from donors with sepsis, donors who died from snakebite or acute kidney injury, controlled donation after cardiac death, older donors, can be considered for KT with an acceptable outcome. The acceptable outcome can be achieved with dual KT using kidneys from expanded criteria donors in older population. Dual KT from pediatric donors to adult recipients or from adult marginal DDs is a promising way to expand the donor pool. Carefully selected donor with HIV, HCV, and HBV positivity is not a contraindication for living kidney donation. Careful and meticulous selection of patient and donor is essential for successful outcome. Affordable or free transplantation is other way to increase transplantation rate in developing country. The community support can make transplantation available free to the poor patients under community-government partnership. Various steps should be taken to promote LDKT and DDKT program.

AIM To avoid desensitization protocols and ABO incompatible kidney transplantation (KT) due to high costs and increased risk of infections from intense immunosuppression. METHODS We present institutional ethical review board - approved study of single center 6-way kidney exchange transplantation. The participants comprised ABO incompatibility (n = 1); positive cross-match and/or presence of donor specific antibody (n = 5). The average time required from registration in kidney paired donation (KPD) registry to find suitable donors was 45 d and time required to perform transplants after legal permission was 2 mo. RESULTS Graft and patient survival were 100%, and 100%, respectively. One patient had biopsy-proven acute borderline T cell rejection (Banff update 2013, type 3). Mean serum creatinine was 0.8 mg/dL at 9 mo follow-up. The waiting time in KPD was short as compared to deceased donor KT. CONCLUSION We report first non-simultaneous, single center, 6-way kidney exchange transplantation from India. Our experience will encourage other centers in India to undertake this practice.

Sjogren's syndrome is a systemic autoimmune disorder characterized by chronic inflammation of the exocrine glands with extra-glandular manifestations. Renal involvement occurs in 18–67% of cases, with chronic tubulo-interstitial nephritis being the most frequent pathology which can lead to distal renal tubular acidosis characterized by normal anion gap acidosis with hypokalemia and alkaline urinary pH. Hypokalemic periodic paralysis can be primary or secondary to potassium deficiency which can arise from several causes. Primary Sjogren's syndrome is a rare cause which can lead to renal involvement producing distal renal tubular acidosis with hypokalemic paralysis.

In a living donor kidney transplantation (LDKT) dominated transplant programme, kidney paired donation (KPD) may be a cost-effective and valid alternative strategy to increase LDKT in countries with limited resources where deceased donation kidney transplantation (DDKT) is in the initial stages. Here, we report our experience of 300 single-centre KPD transplantations to increase LDKT in India. Between January 2000 and July 2016, 3616 LDKT and 561 DDKT were performed at our transplantation centre, 300 (8.3%) using KPD. The reasons for joining KPD among transplanted patients were ABO incompatibility (n = 222), positive cross-match (n = 59) and better matching (n = 19). A total of 124 two-way (n = 248), 14 three-way (n = 42), one four-way (n = 4) and one six-way exchange (n = 6) yielded 300 KPD transplants. Death-censored graft and patient survival were 96% (n = 288) and 83.3% (n = 250), respectively. The mean serum creatinine was 1.3 mg/dl at a follow-up of 3 ± 3 years. We credit the success of our KPD programme to maintaining a registry of incompatible pairs, counselling on KPD, a high-volume LDKT programme and teamwork. KPD is legal, cost effective and rapidly growing for facilitating LDKT with incompatible donors. This study provides large-scale evidence for the expansion of single-centre LDKT via KPD when national programmes do not exist.

AIM To report the first international living related two way kidney paired donation (KPD) transplantation from India which occurred on 17th February 2015 after legal permission from authorization committee. METHODS Donor recipient pairs were from Portugal and India who were highly sensitized and ABO incompatible with their spouse respectively. The two donor recipient pairs had negative lymphocyte cross-matching, flow cross-match and donor specific antibody in two way kidney exchange with the intended KPD donor. Local KPD options were fully explored for Indian patient prior to embarking on international KPD. RESULTS Both pairs underwent simultaneous uneventful kidney transplant surgeries and creatinine was 1 mg/dL on tacrolimus based immunosuppression at 11 mo follow up. The uniqueness of these transplantations was that they are first international KPD transplantations in our center. CONCLUSION International KPD will increases quality and quantity of living donor kidney transplantation. This could be an important step to solving the kidney shortage with additional benefit of reduced costs, improved quality and increased access for difficult to match incompatible pairs like O blood group patient with non-O donor and sensitized patient. To the best of our knowledge this is first international KPD transplantation from India.

The combination of kidney paired donation (KPD) with desensitization represents a promising method of increasing the rate of living donor kidney transplantation (LDKT) in immunologically challenging patients. Patients who are difficult to match and desensitize due to strong donor specific antibody are may be transplanted by a combination of desensitization and KPD protocol with more immunologically favorable donor. We present our experience of combination of desensitization protocol with three-way KPD which contributed to successful LDKT in highly sensitized end stage renal disease patient. All recipients were discharged with normal and stable allograft function at 24 mo follow up. We believe that this is first report from India where three-way KPD exchange was performed with the combination of KPD and desensitization. The combination of desensitization protocol with KPD improves access and outcomes of LDKT.
