RESUMEN

Background: There is an enormous knowledge gap on management strategies, clinical outcomes, and follow-up after kidney transplantation (KT) in recipients that have recovered from coronavirus disease (COVID-19). Methods: We conducted a multi-center, retrospective analysis in 23 Indian transplant centres between June 26, 2020 to December 1, 2021 on KT recipients who recovered after COVID-19 infections. We analyzed clinical and biopsy-confirmed acute rejection (AR) incidence and used cox-proportional modeling to estimate multivariate-adjusted hazard ratios (HR) for predictors of AR. We also performed competing risk analysis. Additional outcome measures included graft loss, all-cause mortality, waiting time from a positive real-time polymerase test (RT-PCR) to KT, laboratory parameters, and quality of life in follow-up. Findings: Among 372 KT which included 38(10·21%) ABO-incompatible, 12(3·22%) sensitized, 64(17·20%) coexisting donors with COVID-19 history and 20 (5·37%) recipients with residual radiographic abnormalities, the incidence of AR was 34 (9·1%) with 1(0·26%) death censored graft loss, and 4(1·07%) all-cause mortality over a median (interquartile range) follow-up of 241 (106-350) days. In our cox hazard proportional analysis, absence of oxygen requirement during COVID-19 compared to oxygen need [HR = 0·14(0·03-0·59); p-value = 0·0071], and use of thymoglobulin use compared to other induction strategies [HR = 0·17(0·03-0.95); p-value = 0·044] had a lower risk for AR. Degree of Human leukocyte antigen (HLA) DR mismatch had the highest risk of AR [HR = 10.2(1·74-65·83); p-value = 0·011]. With competing risk analysis, with death as a competing event, HLA DR mismatch, and oxygen requirement continued to be associated with AR. Age, gender, obesity, inflammatory markers, dialysis vintage, steroid use, sensitization and ABO-incompatibility have not been associated with a higher risk of AR. The median duration between COVID-19 real time polymerase test negativity to transplant was 88(40-145) days (overall), and ranged from 88(40-137), 65(42-120), 110(49-190), and 127(64-161) days in World Health Organization ordinal scale ≤ 3, 4, 5, and 6-7, respectively. There was no difference in quality of life, tacrolimus levels, blood counts, and mean serum creatinine assessed in patients with a past COVID-19 infection independent of severity. Interpretation: Our findings support that the outcomes of KT after COVID-19 recovery are excellent with absence of COVID-19 sequelae during follow-up. Additionally, there does not seem to be a need for changes in the induction/immunosuppression regimen based on the severity of COVID-19. Funding: Sanofi.

RESUMEN

BACKGROUND: There is limited current knowledge on feasibility and safety of kidney transplantation in coronavirus disease-19 (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 severe acute respiratory syndrome coronavirus 2 PCR tests, normal chest imaging with complete resolution of symptom for at least 28 d and significant social distancing for 14 d before 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 d (overall) and increased significantly from asymptomatic, mild, moderate, and severe disease (49, 57, 83, 94 d, P 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) d 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 pretransplant evaluation, and individualized risk-benefit analysis. Further large-scale prospective studies with longer follow-up will better clarify our initial findings. To date, this remains the first and the largest study of kidney transplantation in COVID-19 survivors.

RESUMEN

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.

RESUMEN

The outcome of chronic kidney disease (CKD) patients admitted to the Intensive Care Unit (ICU) is difficult to predict. This study assessed the outcome of CKD patients admitted to the ICU and evaluated prediction of 30-day mortality using the Acute Physiology and Chronic Health Evaluation (APACHE II), Simplified Acute Physiology Score (SAPS II), and Sequential Organ Failure Assessment (SOFA) score. One hundred consecutive CKD patients admitted to the ICU at a tertiary care hospital, Ahmedabad between 2011 and 2013 were included prospectively. Data on demographics, indication for admission, cause of CKD, use of vasoactive drugs and mechanical ventilation (MV), mode of renal replacement therapy (RRT), and 30-day mortality were recorded. The APACHE II, SAPS II, and SOFA scores were calculated based on the admission characteristics. The mean APACHE II, SAPS II, and SOFA scores were 28.22 ± 7.53, 43.04 ± 16.40, and 10.39 ± 5.20, respectively, and area under receiver operating characteristics curve in predicting 30-day mortality were 0.961, 0.994, and 0.950, respectively. The scores were significantly higher in 30-day nonsurvivors as compared to survivors (P = 0.001). During the ICU stay, MV and vasoactive drugs were required in 57% and 67% of the patients, respectively, and the requirement was significantly greater in nonsurvivors as compared to survivors (P = 0.001). About 85% of patients were on intermittent hemodialysis and 15% of patients were on continuous venovenous hemodiafiltration. Sepsis was the main reason for hospital admission, and the mean length of stay in the ICU was 7.74 ± 5.34 days. The study indicates that all three scores (APACHE II, SAPS II, and SOFA) perform equally well and have equal diagnostic utility in predicting 30-day mortality.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Atypical hemolytic uremic syndrome (aHUS) although rare is the commonest cause of acute renal failure (ARF) in children and has poor prognosis. We present single centre experience of aHUS. Thirty six children (29 males, 7 females) with mean age, 7.9 years presented with ARF, 2 children also had tonic-clonic type convulsions. Their hematology examination revealed hemolytic anemia with s. creatinine (SCr), 5.54 mg/dl. Acute HUS was observed in 75 %, acute on chronic HUS in 19.4 % and patchy cortical necrosis (PCN) in 5.6 % biopsies. Mean 5.4 plasma exchanges (PE) were carried out. Supportive management of anti-hypertensives and prednisone was also given. Recovery end points were establishment of urine output, improvement of SCr and hematological profile. Hematology and renal function profile improved variably in all children, 5.6 % died, relapse was observed in 80.5 % over mean 70 days; 13.9 % children are doing well over mean follow-up of 268.8 days. Thus poor prognosis was observed in 86.1 % children. Children with acute on chronic HUS and PCN did not recover. Six children who recovered had acute HUS. aHUS in Indian children occurs at an older age of around 8 years and chronic/irreversible changes on histopathology examination are harbingers of poor prognosis. PE is life-saving however further research for developing strategies to improve long-term survival is needed.

RESUMEN

BACKGROUND: Stem cell therapy (SCT) is used for immunosuppression minimization in renal transplantation (RT). We carried out a prospective study to evaluate the benefits of co-infusion of donor adipose-derived mesenchymal stem cells (AD-MSC) + hematopoietic stem cells (HSC) in living donor RT (LDRT) under non-myeloablative conditioning. METHODS: In a demographically balanced three-armed LDRT trial with 95 patients in each arm, group-1 received portal co-infusion of AD-MSC + HSC, group-2 received HSC and group-3 received no SCT. Lymphoid irradiation and anti-thyroglobulin were used for conditioning. RESULTS: SCT was safe. At 1 and 5 years post-transplant, patient survival was 100% and 94.7% in group-1, 100% and 95.7% in group-2, and 94.7% and 84% in group-3, death-censored graft survival was 100% and 94.6% in group-1, 100% and 91.3% in group-2, and 98.9% and 94.4% in group-3 with mean serum creatinine (mg/dL) of 1.38 and 1.39 in group-1, 1.48 and 1.51 in group-2, and 1.29 and 1.42 and in group-3. Rejection episodes and immunosuppression requirement were lesser in SCT groups versus controls with best results noted in group-1. CONCLUSION: Coinfusion of donor AD-MSC +HSC in portal circulation pre-transplant under non-myeloablative conditioning is safe and effective for immunosuppression minimization in LDRT.

RESUMEN

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.

RESUMEN

Fungal pathogens can be the source of serious and sometimes fatal infections following organ transplantation. To the best of our knowledge, we present the first case of cutaneous blastomycosis in a renal allograft recipient in India, a country outside the known endemic regions. This case, with the very rare and unexpected diagnosis of blastomycosis, not only reflects the tremendous diversity of infections in transplant recipients but also emphasizes the utility of serological methods even in the immunosuppressed host.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Acute kidney injury (AKI) is one of the most challenging and serious complications of pregnancy. We present our experience on the clinical profile and outcome of 57 patients with pregnancy-related AKI, of a total of 580 patients with AKI seen during the study period. This is a prospective single-center study in a civil hospital conducted from January to December 2010. The most common age group of the study patients was 20-25 years; 43.8% of the patients had received antenatal care. AKI was observed in the puerperium (n = 34), early pregnancy (n = 10) and late pregnancy (n = 13). The cause of AKI included puerperal sepsis (63.1%), pregnancy-induced hypertension (PIH) (33.33%), post-abortion (22.80%), ante-partum hemorrhage (APH) (14%) and post-partum hemorrhage (PPH) (8%). Complete, partial and no renal recovery was observed in 52.64%, 21.05% and 26.31% of the patients, respectively. Low platelet count and plasma fibrinogen and high bilirubin, D-dimer and activated partial thromboplast in time were observed more commonly in patients with partial recovery. Of the 57 patients, 50 received hemodialysis, three received peritoneal dialysis and seven patients were managed conservatively. A total of 13 patients developed cortical necrosis that was associated with sepsis in six, PPH and pre-eclampsia/eclampsia in three patients each and APH in one. Nine patients died, and the cause of death was septicemia in four, pre-eclampsia in three and APH and PPH in one patient each. In our study, puerperal sepsis was the most common etiological factor for pregnancy-related AKI. Prolonged oliguria or anuria were bad prognostic factors for renal recovery. Sepsis, thrombocytopenia, disseminated intra-vascular coagulation and liver involvement were associated with increased mortality.

RESUMEN

Acute renal failure (ARF) is a serious medical complication during pregnancy, and, in the post-partum period, is associated with significant maternal morbidity and mortality as well as fetal loss. The objective of our study is to find the etiology and maternal outcome of ARF during pregnancy. The study was conducted at the Obstetrics and Gynecology Department of the Institute of Kidney Disease and Research Center, Ahmedabad, India from January 2009 to January 2011. Fifty previously healthy patients who developed ARF, diagnosed on oliguria and serum creatinine >2 mg%, were included in the study. Patients with a known history of renal disease, diabetes and hypertension were excluded from the study. All patients were followed-up for a period of six months. Patient re-cords, demographic data, urine output on admission and preceding history of antepartum hemorrhage (APH), post-partum hemorrhage (PPH), septicemia, operative interventions and retained product of conception were noted and need for dialysis was considered. Patients were thoroughly examined and baseline biochemical investigations and renal and obstetrical ultrasound were performed on each patient and bacterial culture sensitivity on blood, urine or vaginal swabs were performed in selected patients. The age range was 19-38 years (mean 26 ± 3.8). The first trimester, second trimester and puerperal groups comprised of four (8%), 25 (50%) and 21 patients (42%), respectively. Hemorrhage was the etiology for ARF in 15 (30%), APH in ten (20%) and PPH in five (10%) patients. Eleven (22%) patients had lower segment cesarian section (LSCS) while 36 (78%) patients had normal vaginal delivery. In 20 (40%) patients, puerperal sepsis was the etiological factor, while pre-eclampsia, eclampsia and HELLP syndrome accounted for 18 (36%) patients. Two (4%) patients had disseminated intravascular coagulation on presentation while one (2%) patient was diagnosed with hemolytic uremic syndrome. Maternal mortality was 12% (n = 6). Of the 38 (88%) surviving patients, 21 (42%) had complete recovery of renal function, eight (16%) patients had partial and 15 (30%) patients required dialysis on a long-term basis. ARF in pregnancy is associated with poor maternal and renal outcome if not detected and treated in time.

RESUMEN

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.

RESUMEN

Churg-Strauss syndrome (CSS) also called allergic granulomatosis and angiitis is a multisystem disorder. Churg-Strauss syndrome is defined as an eosinophil-rich, granulomatous inflammation involving the respiratory tract, along with necrotizing vasculitis affecting small- to medium-sized vessels, and is associated with asthma and eosinophilia. Renal involvement in CSS varies from 26 to 88 % but is usually of mild to moderate stage, and advanced renal failure is uncommon. We encountered an unusual case of 27-year-old man with asthma and primary focal segmental glomerulosclerosis diagnosed as CSS showing myeloperoxidase anti-neutrophil cytoplasmic antibody-associated acute kidney injury with crescentic glomerulonephritis. Patient responded to steroid and cyclophosphamide. Over a follow-up of 2 months, he has no hematuria/eosinophilia and serum creatinine of 2.3 mg/dL has decreased to 1.7 mg/dL.

RESUMEN

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.
