    ABSTRACT: New-onset diabetes after transplant (NODAT) is associated with serious morbidity and mortality. The incidence of NODAT is higher with tacrolimus (Tac) compared with cyclosporine (CsA); however, the effects of switching from Tac to CsA in NODAT have not been studied well. This was a single-center, open-label, prospective, randomized study, including renal transplant recipients who were on Tac-based immunosuppression and developed NODAT. Those with pretransplant diabetes, hypersensitivity to CsA or Tac, severe infections, and denying consent were excluded. Subjects were randomized to either switch to CsA or to continue on Tac. Fasting and postprandial plasma glucose, fasting insulin and C-peptide levels, insulin and oral hypoglycaemic agents (OHA) use were monitored monthly for 3 months, whereas glycosylated haemoglobin (HbA1c) was checked at baseline and 3 months. Sixty-seven subjects were randomized to switch to CsA (n = 32) or continuation of Tac (n = 35). Both groups had similar baseline characteristics. After randomization, there was significant improvement in fasting plasma glucose, fasting insulin levels, C-peptide levels, and insulin requirement in both groups, whereas HbA1c improved significantly only in the CsA group. The decline in fasting plasma glucose and insulin requirement was more significant in subjects on CsA. An equal number of subjects in each group (59.4% in CsA group and 40% in Tac group, P = ns) had resolution of NODAT. Weight gain was more significant in the CsA group; however, there was no difference in other side effects or rejection episodes. A switch from tacrolimus to cyclosporine is a safe and effective strategy in patients with NODAT. Copyright © 2015 Elsevier Inc. All rights reserved.

    ABSTRACT: A 60-year male was admitted with advanced renal failure and bilaterally enlarged kidneys. Kidney biopsy revealed diffuse interstitial infiltration by CD20 + lymphomatous cells suggestive of diffuse large B-cell, non-Hodgkin's lymphoma. Bone marrow examination was negative for malignant cells. Positron emission tomography-computed tomography showed uniformly diffuse and avid flurodeoxy glucose uptake in both kidneys, multiple hypodense areas of both lobes of liver, and axial and appendicular skeleton. Patient was treated with rituximab, cyclophosphamide, hydroxydaunorubicin, vincristine and prednisolone, became afebrile and serum creatinine normalized.

    ABSTRACT: We report a 50-year-old female who presented with inflammatory arthritis, upper respiratory tract symptoms, and microscopic hematuria with nephrotic range proteinuria. Antineutrophil cytoplasmic antibodies (ANCA) were detectable and kidney biopsy showed pauci-immune focal necrotizing crescentic glomerulonephritis. She was treated with pulse intravenous cyclophosphamide (CYC) and prednisolone. Patient developed severe leucopenia after the first dose and subsequently had leucopenia to low dose CYC, mycophenolate mofetil and azathioprine were also tried. However, patient developed leukopenia with all the above agents. Initiation of tacrolimus (TAC) was followed by dramatic response: Proteinuria decreased, serum albumin normalized and C-ANCA and anti-PR3 ANCA assays became negative. This is the first successful case of TAC as an induction agent in a patient with GPA (ANCA associated vasculitis with renal involvement).

    ABSTRACT: Pulse methyl prednisolone followed by oral prednisolone and abrupt switch to chlorambucil/cyclophosphamide (Ponticelli/modified Ponticelli regimen) is used in patients with idiopathic membranous nephropathy. This therapy where steroids are stopped abruptly is unphysiologic and expected to have hypothalamic pituitary adrenal (HPA) axis suppression; however, this has not been evaluated. A total of 13 consecutive adult patients with idiopathic membranous nephropathy who had completed modified Ponticelli regimen were studied. The regimen included administration of pulse methylprednisolone 1 g for 3 days followed by oral prednisolone 0.5 mg/kg/day for 27 days followed by oral cyclophosphamide at a dose of 2 mg/kg/day for the next month. This was repeated for three courses. Patients who had received corticosteroids prior to therapy were excluded. The HPA axis was evaluated after 1 month of completing the last course of steroid therapy. The evaluation was done using a low-dose adrenocorticotropic hormone stimulation test. A single intravenous bolus dose of synacthen (1 μg) was given at 9.00 am and the serum cortisol levels were estimated by radioimmunoassay at 0, 30, and 60 min. A peak cortisol level of 550 nmol/L or higher was considered as normal. Mean baseline cortisol levels was 662.3 ± 294.6 nmol/L and peak cortisol level was 767 ± 304.4 nmol/L. A total of 6 patients (46.2%) had low basal cortisol levels, only 3 (23%) had both basal and peak cortisol levels < 550 nmol/L suggestive of HPA axis suppression. To conclude, 23% of patients had suppression of HPA axis after modified Ponticelli regimen.

    ABSTRACT: This study was designed to compare the outcomes of spousal donor (SD) with related donor (RD) kidney transplants performed at our center between January 2010 and October 2012. A total of 323 adult, ABO-compatible kidney transplants (SD 150 [46.4%], RD 173 [53.6%]) were included. Data on outcomes at 6 months post-transplant was collected retrospectively (2010-2011) and prospectively (January-October 2012). Majority of the donors (SD 88%, RD 72.2%) were females. In the SD group, donors were younger (SD 35.6 ± 8.2 years, RD 45.2 ± 11.5 years; P < 0.0001), whereas recipients were older (SD 42.2 ± 8.3 years, RD 30.0 ± 9.5 years; P < 0.0001). A significantly higher proportion of patients in the SD group were given induction therapy (43% vs 12%; P < 0.001). Biopsy proven acute rejections were more common in the RD group (16% vs 28.3%; P = 0.01). Majority (80.8%) of the acute rejections occurred in the first 2 weeks post-transplant in both groups. Isolated acute cellular rejections (ACRs) and isolated antibody mediated rejections constituted 50% and 25% of rejection episodes in both groups, whereas the remainder had histological evidence of both. The proportion of steroid responsive ACRs was similar in both groups (SD 83.3%, RD 65.4%; P = 0.2). The number of patients with abnormal graft function at the end of the study was higher in the RD group (2.3% vs. 12.3%; P = 0.001). Patient survival and infection rates were similar in the two groups. We conclude that short-term outcomes of SD transplants are not inferior to RD transplants. Lesser use of induction therapy in the RD group may explain the poorer outcomes as compared to the SD group.

    ABSTRACT: Glomerular diseases are an important cause of chronic renal failure in developing countries. The spectrum of diseases causing nephrotic syndrome is changing globally in the last few decades. The aim of this prospective study was to look at this spectrum at a tertiary care center in North India and to analyze the changing trends over the last five decades. Patients in the age group 18-60 years with nephrotic syndrome were consecutively included in the study. Renal biopsies were performed in all patients and were subjected to light microscopy, immunofluorescence (IF) and electron microscopy (EM). While the IF was performed in 78% of cases, EM was available in one-fourth of cases. During 2002-2007, 364 patients (60.2% males) were included in the study. The mean age was 31.5 years. Primary glomerular diseases accounted for 89% of cases while lupus nephritis was the most common secondary glomerular disease. Focal segmental glomerulosclerosis (FSGS) accounted for 30.6% of primary glomerular diseases making it the most common cause of nephrotic syndrome. It was followed by membranous glomerulonephritis (MGN) in 24.4%, mesangiocapillary glomerulonephritis in 17.9% and minimal change disease in 14.8%. In the age group >40 years, MGN was the most common lesion (32.5%) followed by FSGS (27.7%). Over the last five decades, there was a nearly five-fold increase in the incidence of FSGS, 3-fold increase in MGN and a 10-fold reduction in diffuse proliferative glomerulonephritis while there was no major change in incidence of other diseases. The biopsy diagnosis of FSGS has increased considerably in last few decades and it is now the most common cause of nephrotic syndrome in adults in North India. MGN is the most common lesion in patients over 40 years of age.

    ABSTRACT: Diabetes mellitus is a common cause of pyelonephritis. Both emphysematous pyelonephritis (EPN) and non-EPN (NEPN) are associated with poor outcome. This study was aimed at analyzing the clinical features, microbiological profile, prognostic factors, and treatment outcome of pyelonephritis in diabetic patients. A total of 105 diabetic patients with pyelonephritis were admitted from July 2010 to June 2012. Patients were treated with appropriate antibiotics and percutaneous drainage (PCD) as indicated. Nephrectomy was carried out in patients of EPN who were refractory to conservative measures. NEPN and EPN were seen in 79 (75.2%) and 26 (24.7%) patients, respectively. Escherichia coli was the most common organism. Pyelonephritis was associated with renal abscess and papillary necrosis in 13 (12.4%) and 4 (3.8%) patients with EPN and NEPN, respectively. Worsening of renal functions were seen in 92 and 93% of patients with EPN and NEPN, respectively. Class 1 EPN was seen in 2 (7.7%), Class II in 8 (30.7%), IIIa in 7 (27%), IIIb in 5 (19.3), and IV in 4 (15.4%) patients. Antibiotics alone were sufficient in 38.5% of EPN versus 62% in NEPN; additional PCD was required in 42.3% in EPN and 21.4% in NEPN. Nephrectomy was required in 5 (19.2%) EPN patients with Class IIIB or IV. A total of 13 patients (12.4%) expired, 4 (15.4%) in EPN, and 9 (11.4%) in NEPN group. Patients with EPN had a higher incidence of shock (6% vs. 0; P < 0.05) and poorly controlled blood sugar (26% vs. 50%; P < 0.05) compared with NEPN. Presence of shock and altered sensorium were associated with poor outcome in patients with EPN. Diabetics with pyelonephritis have severe disease. Patients of EPN have poorer treatment outcome compared with those with NEPN. However, there is no difference in the mortality, but a greater need of nephrectomy in EPN compared with NEPN patients. Presence of shock and altered sensorium at presentation were poor prognostic factors in EPN.

    ABSTRACT: Non-depleting antibody induction has the best safety profile in transplant recipients without an increased risk of infection or malignancy. This observational study was performed in intermediate immunologic risk live donor renal transplants to assess basiliximab efficacy in patients on tacrolimus, mycophenolate, and prednisolone immunosuppression. A total of 46 patients on basiliximab induction were compared to risk matched 56 controls at the end of 6 and 12 months post-transplant. An additional cost of approximately Rs. 100,000/patient was incurred by the basiliximab group. The incidence of biopsy proven acute rejection in the control group (12.5%, 6 months and 20.5%, 1 year) and the basiliximab group (13%, 6 months and 18.9%, 1 year) was similar. At 6 months, there was a non-significant trend toward more steroid sensitive rejections and better glomerular filtration rate preservation in the basiliximab group (83.3%, 71.9 ml/min) versus the control group (28.6%, 62.2 ml/min). However, this difference was lost at 1 year (70.1 ml/min vs. 67.6 ml/min). The incidence of infections was similar and none of the patients had a malignancy. Death censored graft survival (94.6% basiliximab and 94.8% control) and the mean number of hospitalizations for all reasons at the end of 1 year were not different among the two groups. In our study, basiliximab induction did not confer an additional advantage in the intermediate risk live donor transplants in patients on tacrolimus and mycophenolate based triple drug immunosuppression.

    ABSTRACT: Monoclonal immunoglobulin deposition disease (MIDD) is an uncommon disease with a peak incidence between the 5(th) and 6(th) decades of life. It is characterized by non-fibrillar, Congo red negative deposition of monoclonal immunoglobulins in various organs, including in the kidneys. MIDD can be of three types depending on the composition of the deposits, and includes light chain deposition disease (LCDD), heavy chain deposition disease and light and heavy chain deposition disease, of which LCDD is the most common. Renal involvement is a universal finding in MIDD, and is in the form of renal insufficiency, microscopic hematuria and nephrotic range proteinuria. Gross hematuria is a rare occurrence. Renal biopsy usually shows nodular sclerosing glomerulopathy on light microscopy and diffuse linear staining of glomerular and tubular basement membrane on immunofluorescence microscopy. We report a young male who presented with rapidly progressive renal failure and gross hematuria and was diagnosed as LCDD with nodular glomerulopathy and crescents on renal biopsy.

    ABSTRACT: Post-transplant lymphoproliferative disorder (PTLD) is a well-recognized, but uncommon complication of organ transplantation. This study was a retrospective analysis of 2000 patients who underwent renal transplantation over a period of 30 years (1980-2010). Forty malignancies were diagnosed in 36 patients. Of these, 29 patients (1.45%) had PTLD (7 females, 22 males) accounting for 72.5% of all malignancies after transplantation. Twenty-two (75.8%) developed non-Hodgkin lymphoma and seven patients (24.2%) had myeloma. Diagnosis was made by biopsy of the involved organ in 21 patients (72.4%) and aspiration cytology in five patients (17.2%). In three patients, the diagnosis was made only at autopsy. Mean age at the time of diagnosis of PTLD was 41.9 years (range 21-69 years). Time interval from transplantation to the diagnosis of PTLD ranged from 3 months to 144 months with a median of 48 months. Only five patients (17.2%) developed PTLD within a year of transplantation. Twelve patients developed PTLD 1-5 years and 12 patients 5-10 years after transplantation. Organ involvement was extra nodal in 18 patients (82%). Thirteen (59%) patients had disseminated disease and nine (41%) had localized involvement of a single organ (brain-3, liver-1, allograft-1, perigraft node-1, retroperitoneal lymph nodes-3). Infiltration of the graft was noted in two patients. Patients with myeloma presented with backache, pathological fracture, unexplained anemia or graft dysfunction. PTLD was of B cell origin in 20 cases (70%). CD 20 staining was performed in 10 recent cases, of which 8 stained positive. Of the 26 patients diagnosed during life, 20 (69%) died within 1 year of diagnosis despite therapy. In conclusion, PTLD is encountered late after renal transplantation in the majority of our patients and is associated with a dismal outcome. The late onset in the majority of patients suggests that it is unlikely to be Epstein Barr virus related.

    ABSTRACT: This study was carried out to evaluate the efficacy and safety of doxercalciferol as therapy for secondary hyperparathyroidism (SHPT) in patients with chronic kidney disease (CKD) stage 4 in a prospective clinical trial. A total of 35 CKD-4 patients who had a baseline parathyroid hormone (iPTH) >150 pg/mL and had not received any vitamin D analog in the preceding 8 weeks were followed up at intervals of 6 weeks for 18 weeks on oral therapy with doxercalciferol. The starting dose was 1.5 μg/day, and the dose was increased in steps of 1 μg/day if iPTH did not decrease by at least 30% on the subsequent visit. Doxercalciferol was stopped temporarily if low iPTH (<70 pg/mL), hypercalcemia (>10.7 mg/dL), or severe hyperphosphatemia (>8.0 mg/dL) occurred, and was restarted at a lower dose on reversal of these abnormalities. Calcium acetate was the only phosphate binder used. Mean iPTH decreased by 35.4 ± 4.4% from 381.7 ± 31.3 pg/mL to 237.9 ± 25.7 pg/mL (P < 0.001). The proportion of patients who achieved 30% and 50% suppression of iPTH levels was 83% and 72%, respectively. Mean serum calcium, phosphorus, and calcium-phosphorus product values did not differ significantly from the baseline values. Four, two, and nine patients developed hypercalcemia, severe hyperphosphatemia, and high CaxP (>55), respectively. Almost all patients recovered to an acceptable level within 2 weeks of stopping doxercalciferol and adjusting the phosphate binder dose. In all, 21 patients required temporary stoppage of therapy. Most of them were restarted on therapy at a reduced dose during the study. It can, therefore, be concluded that doxercalciferol is effective in controlling SHPT in CKD-4 patients with an acceptable risk of hyperphosphatemia and hypercalcemia.

    ABSTRACT: Abnormalities in mineral and bone disease are common in chronic kidney disease (CKD). Evaluation of bone health requires measurement of parameters of bone turnover, mineralization, and volume. There are no data on bone health in CKD patients from India. In this cross-sectional study, we evaluated serum biomarkers of bone turnover: Bone-specific alkaline phosphatase (BAP) and total deoxypyridinoline (tDPD) along with parathyroid hormone, 25(OH) vitamin D, and bone mineral density (BMD) using dual absorption X-ray absorptiometry in a cohort of 74 treatment-naive patients with newly diagnosed stage 4 and 5 CKD (age 42 ± 14.5 years, 54 men) and 52 non-CKD volunteers (age 40.2 ± 9.3 years, 40 men). Compared to the controls, CKD subjects showed elevated intact PTH (iPTH), BAP, and tDPD and lower BMD. There was a strong correlation between iPTH and BAP (r = 0.88, P < 0.0001), iPTH and tDPD (r = 0.51, P < 0.0001), and BAP and tDPD (r = 0.46, P = 0.0004). The iPTH elevation was greater than twice the upper range of normal in 73% cases, and BAP was >40 U/L in 66% cases. The combination of these markers suggests high turnover bone disease in over 60% cases. The prevalence of osteopenia and osteoporosis was 37% and 12%, respectively. Osteoporotic subjects had higher iPTH, BAP, and tDPD, suggesting a role of high turnover in genesis of osteoporosis. Vitamin D deficiency was seen in 80%, and another 13% had insufficient levels. Vitamin D correlated inversely with BAP (r = -0.3, P = 0.009), and levels were lower in those with iPTH >300 pg/ml (P = 0.0.04). In conclusion, over 60% of newly diagnosed Indian stage 4-5 CKD patients show biochemical parameters consistent with high turnover bone disease. High turnover could contribute to the development of osteoporosis in CKD subjects. Deficiency of 25 (OH) vitamin D is widespread and seems to have a role in the genesis of renal bone disease. Studies on the effect of supplementation of native vitamin D are needed.
