Focal segmental glomerulosclerosis (FSGS) is the most common cause of adult-onset nephrotic syndrome, but its pathophysiology is poorly understood. The question as to why only a subset of patients responds to treatment in unanswered. In the past few years, change of podocytic phenotype from stationary type in health to migratory type in disease has been described, of which loss of subpodocytic space is a surrogate marker. Diagnostic biopsies of adult-onset steroid-resistant calcineurin inhibitor-naïve primary FSGS cases, which were subsequently treated with tacrolimus were included in this retrospective study conducted from 2011 to 2013. The ultrastructure of all cases was studied in detail, especially in context to the presence or absence of subpodocytic space. In the present study, we have compared presence or absence of subpodocytic space in tacrolimus-responsive versus tacrolimus-resistant cases to identify potential electron microscopic features predictive of response to treatment, of which loss of subpodocytic space indicating migratory phenotype is the most important and consistent feature. The present series included 7 tacrolimus responsive cases (includes two cases with partial response) and seven tacrolimus-resistant cases. The tacrolimus-resistant patients were of older age, had a longer duration of illness, and a lower eGFR as compared to tacrolimus responsive cases. The subpodocytic space was preserved in patients on tacrolimus with complete remission and lost in patients with partial response and tacrolimus-resistant cases. [ABSTRACT FROM AUTHOR]

A 63-year-old diabetic gentleman with microvascular complications presented with advanced azotemia and anemia. He was stabilized with blood transfusion and hemodialysis. With the probable diagnosis of diabetic nephropathy-related end-stage renal disease, he underwent kidney transplantation. He had delayed graft function. Graft biopsy done on the 2nd postoperative day showed acute tubular necrosis. Graft biopsy repeated after 2 weeks for persistent graft dysfunction showed myeloma cast nephropathy (MCN) and light chain proximal tubulopathy. Work-up for multiple myeloma was positive. He was started on plasmapheresis and chemotherapy. However, he suffered sudden cardiac death during dialysis after 1 week. The presence of MCN in the early graft biopsy implies that it must have been the cause for his native kidney failure. Thus, renal failure in a diabetic should not always be presumed to be due to diabetic nephropathy, and kidney biopsy should be done in diabetics with atypical features. [ABSTRACT FROM AUTHOR]

IgG4-related kidney disease (IgG4 RKD) is increasingly reported with varied manifestations. The present study was carried out to study the spectrum of IgG4 RKD. All patients with renal manifestation associated with conditions known to be associated with IgG4-related diseases (IgG4 RDs), or renal imaging or histology suggestive of IgG4 RKD were included and evaluated further. Patients with known extrarenal IgG4RD were also screened for renal involvement. Out of 40 patients screened over a period of 15 months, IgG4 RKD was diagnosed in 8. Majority were male (87.5%) with mean age being 56 years. Disease spectrum ranged from normal renal function in one to renal failure requiring dialysis in another two patients. Significant proteinuria was uncommon (12.5%) while hematuria was not seen in any patient. Tubulointerstitial nephritis was seen in all four patients who underwent kidney biopsy. Two patients had associated glomerular lesions in the form of immune complex crescentic glomerulonephritis. The most common imaging abnormality was hypodense renal lesions seen in 2 patients. Elevated IgG4 levels had 87.5% sensitivity and 78.3% specificity for IgG4 RKD and levels did not correlate with disease severity. Of 4 patients treated with steroids, 3 showed improvement in renal function. IgG4 RKD is an uncommon disease even at a referral tertiary care center. Elevated IgG4 levels alone are neither sensitive nor specific for the diagnosis of IgG4 RKD, and a combination of clinical, imaging, serological, and histological features are required for diagnosis.

The spectrum of biopsy-proven glomerular disease was studied from a single center in Northwestern India, among adolescents aged 13-19 years. From January 2009 to December 2012, a total of 177 patients with biopsy-proven glomerular disease were studied. The same pathologist reported all the biopsy specimens after subjecting to light, immunofluorescence, and electron microscopy. The clinical profile and laboratory findings of the patients were correlated with the histopathological spectrum of glomerular diseases. Males formed 71.19% (n = 126) and the remaining 28.81% (n = 51) were females. Lupus nephritis had a strong female predominance, whereas minimal change disease (MCD) and focal segmental glomerulosclerosis (FSGS) had a male predominance. Nephrotic syndrome was the indication for biopsy in 65% of the cases. Rapidly progressive renal failure and acute nephritis were the next common indications accounting for 14% and 7%, respectively. FSGS was the most common glomerular disease in adolescents (n = 45, 25.4%). The next common were MCD and lupus nephritis each contributing 21.6% and 10.7%, respectively. Primary glomerular diseases accounted for 84.75% (n = 150) of the total. The remaining 15.25% (n = 27) were attributed to secondary glomerular diseases, of which lupus nephritis was the most common, i.e., in 70.4% patients (n = 19). FSGS was the most common histology in adolescent nephrotic participants (37%). MCD was the next common, found in 31% of nephrotic patients. Electron microscopy changed the diagnosis made by light microscopy and immunofluorescence in 5.6% cases only, and it confirmed the diagnosis in another 21.6%. Kidney biopsy in adolescents is a safe procedure. The spectrum of glomerular diseases in adolescents is different from that seen in adults and smaller children. [ABSTRACT FROM AUTHOR]

Donation after circulatory death (DCD) has never been attempted in India because of legal constraints and lack of guidelines for the withdrawal of life support in end-of-life situations. The present report describes the initial experience of transplantation of organs from DCD donors in a tertiary care center in India. Between 2011 and 2015, five donors had kidneys retrieved after cardiac arrest. These patients were declared dead after waiting for 5 min with no electrocardiographic signal on monitor following cardiopulmonary resuscitation (CPR), which was restarted in three patients till organ retrieval. All donors received heparin and underwent rapid cannulation of aorta, infusion of preservative cold solution, and immediate surface cooling of organs during retrieval surgery. 9/10 kidneys were utilized. Mean donor age was 29.6 ± 16.3 years, M:F 4:1 and mean age of recipients was 38.7 ± 10.8 years, M:F 7:2. Seven patients required dialysis in postoperative period. Mean postoperative day 0 urine output was 1.9 ± 2.6 L. Baseline creatinine achieved was 1.38 ± 0.35 mg/dl after a mean duration of 26.12 ± 15.4 days. Kidneys from donors where CPR was continued after the declaration of death (n = 3) had better recovery of renal function (time to reach baseline creatinine 21.2 ± 7.2 vs. 34.3 ± 23.7 days, baseline creatinine 1.36 ± 0.25 vs. 1.52 ± 0.45 mg%). In donors without CPR, one kidney never functioned and others had patchy cortical necrosis on protocol biopsy, which was not seen in the kidneys from donors with CPR. Kidneys from DCD donors can serve as a useful adjunct in deceased donor program. Continuing CPR after the declaration of death seems to help in improving outcomes. [ABSTRACT FROM AUTHOR]

Anti-glomerular basement (anti-GBM) disease is an uncommon disorder with a bimodal age of presentation. Patients presenting with dialysis-dependent renal failure have poor renal outcomes. There is limited data regarding the clinical presentation and outcomes of anti-GBM disease from India. We conducted this prospective study to analyze the clinical presentation and outcomes of anti-GBM disease at a large tertiary care hospital in North India over 1 1/2 years. Subjects with a biopsy proven anti-GBM disease (light microscopic examination showing crescents and immunofluorescence examination showing linear deposition of IgG) with or without positive anti-GBM antibodies in serum were included in the study and followed-up for at least 12 months. All the patients were treated with steroids, cyclophosphamide, and plasma exchange. A total of 17 patients (nine males) were included. The mean age at presentation was 39.11 ± 16.58 (range 11-72) years. Twelve patients (70%) presented with rapidly progressive glomerulonephritis (RPGN), 4 (23.5%) presented with Goodpasture syndrome, while 1 (5.8%) had nephritic syndrome, 7 (41%) were hypertensive, and 14 (82.3%) required dialysis at the time of presentation. Four patients (23.5%) had associated anti-neutrophil cytoplasmic antibody positivity (anti-myeloperoxidase antibodies in all). Fourteen (87.5%) patients had crescentic glomerulonephritis, while 5 (31.25%) showed necrotizing (n = 4) or granulomatous (n = 1) in the vasculitis. Of 16 patients who received treatment, four (23.25%) achieved complete remission. In this single-center study, the majority of anti-GBM disease patients presented with RPGN and had crescentic glomerulonephritis on biopsy with poor treatment outcome. [ABSTRACT FROM AUTHOR]

Massive rectal bleeding is an uncommon presentation of ileal tuberculosis (TB). We report an uncommon cause of anemia in a post-renal transplant patient due to massive lower gastrointestinal (LGI) bleed. The index case had a normal upper and LGI endoscopy, but the 99technetium labeled red blood cell scan showed active bleeding from terminal ileum and caecum. Microscopic examination of the resected specimen revealed tubercular granuloma with acid-fast bacilli. Intestinal TB should be a differential diagnosis for massive LGI bleed in immunosuppressed patients in developing country. [ABSTRACT FROM AUTHOR]

Collapsing focal segmental glomerulosclerosis (cFSGS) is characterized by rapid progression to end-stage renal disease (ESRD). We evaluated the clinicopathological spectrum of cFSGS and compared its clinical behavior to steroid and tacrolimus (TAC)-resistant noncollapsing focal segmental glomerulosclerosis (FSGS). All patients (>14 years) diagnosed with cFSGS were enrolled in the study. Staining for differentiated podocyte markers such as WT 1, PAX and KI67 were performed in all patients. The outcome and histological features of cFSGS was compared with a prospectively followed cohort of steroid and TAC-resistant noncollapsing FSGS. The study included 22 cFSGS patients and 19 cases of steroid and TAC-resistant FSGS. Complete remission, partial remission, steroid resistance, progression to ESRD and death were observed in 13.6%, 4.5%, 27.3%, 36.4% and 18.2% patients, respectively. Patients with cFSGS had higher serum creatinine and more advanced tubulointerstitial changes compared to resistant FSGS. Twenty-six percent of therapy resistant noncollapsing FSGS progressed to ESRD after two years of stopping TAC. However, there was no difference in progression to ESRD between cFSGS and therapy-resistant noncollapsing FSGS at the end of two years. Glomerular collapse in the setting of FSGS is poorly responsive to treatment and has a high rate of progression to ESRD. The long-term prognosis of cFSGS and steroid and TAC-resistant FSGS are similar. [ABSTRACT FROM PUBLISHER]

Collapsing glomerulopathy (CG) is a pathological entity characterized by collapse and wrinkling of glomerular tuft, podocyte dedifferentiation and hyperplasia. CG may be idiopathic or secondary to other diseases. CG has been described with IgA nephropathy, membranous glomerulopathy, diabetic nephropathy, and lupus nephritis. However, till date there is no report of CG in association with the anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV). Here, we present a case of CG that developed during follow-up in a case of AAV with biopsy proven pauci-immune glomerulonephritis. [ABSTRACT FROM AUTHOR]

Proliferative glomerulonephritis occurring as a consequence of monoclonal glomerular deposits of IgG is uncommon. It is a form of renal involvement in monoclonal gammopathy that mimics immune complex glomerulonephritis. Here, we report the first series of proliferative glomerulonephritis with monoclonal IgG deposits (PGNMID) from the Indian subcontinent highlighting use of light chain immunofluorescence (IF) in routine renal biopsy interpretation. We retrieved 6 patients diagnosed as proliferative glomerulonephritis with monoclonal IgG deposits (PGNMID) out of 160 biopsies (3.7%) with membranoproliferative patterns over 5 1/2 years (2009-2014), one of whom had recurrence 6 months post-renal transplant. Four (67%) patients presented with rapidly progressive renal failure and two (33%) with nephrotic syndrome. None of these patients had overt multiple myeloma. The predominant histologic pattern was membranoproliferative with all the biopsies showing IgG3 Kappa deposits on IF. The deposits were primarily subendothelial on electron microscopy.

Steroids are used in the management of drug-induced acute interstitial nephritis (AIN). The present study was undertaken to compare the efficacy of pulse methyl prednisolone with oral prednisolone in the treatment of drug-induced AIN. Patients with biopsy-proven AIN with a history of drug intake were randomized to oral prednisolone (Group 1) 1 mg/kg for 3 weeks or a pulse methyl prednisolone (Group II) 30 mg/kg for 3 days followed by oral prednisolone 1 mg/kg for 2 weeks, tapered over 3 weeks. Kidney biopsy scoring was done for interstitial edema, infiltration and tubular damage. The response was reported as complete remission (CR) (improvement in estimated glomerular filtration rate [eGFR]to ≥60 ml/min/1.73 m²), partial remission (PR) (improvement but eGFR <60 ml/min/1.73 m#178;) or resistance (no CR/PR). Atotal of 29 patients, Group I: 16 and Group II: 13 were studied. Offending drugs included nonsteroidal anti-inflammatory drugs, herbal drugs, antibiotics, diuretic, rifampicin and omeprazole. There was no difference in the baseline parameters between the two groups. The biopsy score in Groups I and II was 5.9 ± 1.1 and 5.1 ± 1.2, respectively. At 3 months in Group I, eight patients each (50%) achieved CR and PR. In Group II, 8 (61%) achieved CR and 5 (39%) PR. This was not significantly different. Percentage fall in serum creatinine at 1 week (56%) was higher in CR as compared to (42%) those with PR. (P 0.14). Patients with neutrophil infiltration had higher CR compared to patients with no neutrophil infiltration (P = 0.01). Early steroid therapy, both oral and pulse steroid, is equally effective in achieving remission in drug-induced AIN. [ABSTRACT FROM AUTHOR]

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 FROM AUTHOR]

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 g) 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 FROM AUTHOR]

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 FROM AUTHOR]

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 FROM AUTHOR]

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 FROM AUTHOR]

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.

Monoclonal immunoglobulin deposition disease (MIDD) is an uncommon disease with a peak incidence between the 5th and 6th 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.

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 FROM AUTHOR]

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 FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Signaling through Toll-like receptor-9 (TLR9), a mediator of innate immune responses, could have a role in the pathogenesis of systemic lupus erythematosus (SLE). Some studies have shown an association between polymorphisms in the TLR9 gene and disease manifestations. We investigated whether two single nucleotide polymorphisms (-1486 T>C and +1174 G>A) in the TLR9 gene are associated with the risk of renal involvement in SLE. DNA samples from 112 SLE patients (62 with lupus nephritis) and 100 healthy controls were obtained. TLR9 polymorphisms (-1486 T>C and +1174 G>A) were analyzed by polymerase chain reaction–restriction fragment length polymorphism. Genotype and allelic frequencies were compared between lupus patients and healthy controls. Clinical and laboratory manifestations and activity scores on renal biopsy of patients with lupus nephritis were compared between various genotypes. There was no difference in the frequency of genotype or allele distribution at either of the two loci between lupus patients and controls and in lupus patients with or without nephritis. Patients with CC/CT genotype at the -1486 position had higher serum creatinine (P = 0.03) and Austin activity scores (P = 0.015). Patients with AA/AG genotype at +1174 position showed higher serum creatinine (P = 0.04), proteinuria (P = 0.011), anti-dsDNA titers (P < 0.001) and Austin activity scores (P = 0.003) than the GG genotype. Variations at the -1486 and +1174 positions of TLR9 gene are not associated with increased risk of SLE or that of kidney involvement in North Indians. CC/CT genotypes at -1486 and AA/AG at +1174 positions are associated with more severe kidney disease at presentation. [ABSTRACT FROM AUTHOR]

Uremia is a state of heightened inflammatory activation. This might have an impact on several parameters including anemia management. Inflammation interferes with iron utilization in chronic kidney disease through hepcidin. We studied the body iron stores, degree of inflammatory activation, and pro-hepcidin levels in newly diagnosed patients with end-stage renal disease (ESRD), and compared them with normal population. In addition to clinical examination and anthropometry, the levels of iron, ferritin, C-reactive protein, tumor necrosis factor alfa, interleukin-6, and prohepcidin were estimated. A total of 74 ESRD patients and 52 healthy controls were studied. The ESRD patients had a significantly lower estimated body fat percentage, muscle mass, and albumin; and higher transferrin saturation (TSAT) and raised serum ferritin. Inflammatory activation was evident in the ESRD group as shown by the significantly higher CRP, IL-6, and TNF-α levels. The pro-hepcidin levels were also increased in this group. Half of the ESRD patients had received parenteral iron before referral. Patients who had received intravenous iron showed higher iron, ferritin, and TSAT levels. These patients also showed more marked inflammatory activation, as shown by the significantly higher CRP, TNF-α, and IL-6 levels. We conclude that our ESRD patients showed marked inflammatory activation, which was more pronounced in patients who had received IV iron. High hepcidin levels could explain the functional iron deficiency. The cause of the relatively greater degree of inflammatory activation as well as the relationship with IV iron administration needs further studies. [ABSTRACT FROM AUTHOR]

A 25-year-old female presented with decreased urine output, deranged renal function, thrombocytopenia, and hemolytic anemia. Kidney biopsy was consistent with thrombotic microangiopathy with acute cortical necrosis and Immunoglobulin A nephropathy (IgAN). Hemolytic anemia, thrombocytopenia and urine output improved after five sessions of plasma exchange. Renal function showed a delayed recovery and serum creatinine normalized by 3 months. This is first case of successful use of plasma exchange in hemolytic uremic syndrome with cortical necrosis associated with IgAN. [ABSTRACT FROM AUTHOR]

"Cocoon abdomen" or sclerosing encapsulating peritonitis is a rare cause of intestinal obstruction. It has been described in patients on continuous ambulatory peritoneal dialysis. The exact etiology is unknown, but pathogenesis rests on chronic peritoneal inflammation. No case has been reported so far in patients on hemodialysis. We hereby report a case of cocoon abdomen presenting as refractory ascites with intestinal obstruction in a patient on maintenance hemodialysis. [ABSTRACT FROM AUTHOR]

Purpose: We retrospectively reviewed the CT findings in 24 cases of autosomal dominant polycystic kidney disease (ADPKD) to assess the role of CT in the diagnostic work-up of patients with complicated ADPKD.Material and Methods: Twenty-four patients with ADPKD underwent unenhanced and contrast-enhanced CT for flank pain, haematuria, or fever. The images were retrospectively reviewed for presence of complicated cysts, their morphological features and associated findings in the perinephric space/retroperitoneum.Results: Cyst haemorrhage was present in all patients, seen as high-density cysts, which were mostly bilateral. Most of these cysts had sharply outlined contours, sharp interfaces with adjacent renal parenchyma, imperceptible walls, and homogeneous density, and did not enhance following i.v. contrast administration. However, a few haemorrhagic cysts (9 cysts in 6 patients) showed inhomogeneous density (n=7), dependent layering of high-density blood leading to fluid-fluid level (n=2), and contour irregularity (n=3). CT revealed presence of cyst infection in 6 cases; the involved cysts were larger (average size 4.2 cm) than adjacent cysts, had only a mildly increased or near water density, and showed wall thickening and enhancement. Other findings included air within the infected cyst (n=1), thickening and enhancement of peri- and paranephric fasciae (n=5), and abscesses in the posterior paranephric space and adjoining psoas muscle (n=2). In 2 other patients, although CT suggested cyst infection because of presence of wall enhancement, diagnostic needle aspiration revealed only sterile haemorrhagic fluid. In 1 case, CT revealed a soft tissue density enhancing mass in one of the cysts; this proved to be a renal cell carcinoma by fine-needle biopsy. Calculi were observed in 7 patients, and cyst wall calcification in 11 cases.Conclusion: A combination of unenhanced and contrast-enhanced CT allows correct diagnosis and differentiation amongst the various complications affecting patients with ADPKD. However, in a small subgroup of patients, it may not be possible to differentiate between haemorrhage and infection; such cases require diagnostic needle aspiration for diagnosis.

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 FROM AUTHOR]

Training needs analysis is considered essential to professional and organizational development, for continuing education and for incorporation into professional practice. Increasingly, nurses are encouraged to develop their health promotion role. Despite this there has been relatively little research in Scotland into the health promotion role of the hospital nurse. This study describes the results of a health promotion training needs analysis undertaken on qualified, hospital-based nurses in Lanarkshire, Scotland. Information on the nurses’ current health promotion practices, their attitudes and beliefs, their views on role development and priorities for further training were collated, analysed and discussed within the framework of the Health Action Model. This model was originally designed to assist understanding of the gap that exists between an individual intention to act and the eventual health action. However, in this study the ways in which ’cognitive factors’ (knowledge and beliefs) and ’motivational factors’ (considering values, attitudes and drives) and pressures from social norms and significant others assisted in the understanding of the nurse’s orientation to, and beliefs about, health promotion practice. Fifty-seven per cent of nurses in the study considered health promotion activities to be emerging in clinical care and 4% considered them to be advanced. The interest respondents have in role development and the further integration of health promotion activities into nursing practice was explored by ascertaining the nurses’ attitudes and beliefs about their own health promotion role. Of 107 respondents, a majority 72 (67%) agreed health promotion interventions to be an important function of the nurse with 29 (27%) strongly agreeing (n = 107). Sixty per cent stated they would be interested in developing their role and 30% were very strongly interested. Recommendations are therefore made for future planning and development strategies for the health promotion role of hospital nurses. [ABSTRACT FROM AUTHOR]

Health and lifestyle surveys undertaken in Scotland during 1986-95 were reviewed by interviewing two individuals from each of the 15 Scottish health boards. Information was collected on the number, extent, cost, motivation for, and outputs from the surveys. Thirteen boards had undertaken a total of 30 surveys (15 with adults and 15 with young people). National health status targets were not cited as important reasons for undertaking earlier surveys, but are becoming increasingly important. Accurate records of costs (including opportunity costs) were not kept. Surveys provided new (but unsurprising) information on boards' populations and there was a sense of disappointment at the overall impact of the surveys. Thirteen boards had future plans for surveys with more qualitative and locality-based approaches. [ABSTRACT FROM AUTHOR]

This study assesses the economic benefits of misoprostol in the prophylaxis of gastric ulcers larger than 0.3 cm in patients with osteoarthritis receiving non-steroidal anti-inflammatory drugs. Independent epidemiological data were obtained for patients in Scotland and the West Midlands. Co-diagnosis of arthritis with gastric ulcer recorded in the routine data was substantially less (4% Scotland, 10% West Midlands) than the 21% found at case review. These data were combined with cost and patient management data in a decision analysis model to explore whether prophylactic use of misoprostol altered substantially the average cost of managing gastric ulcer. Using conservative assumptions and a daily dose of 400 micrograms, cost savings per patient to the National Health Service of 5-8 pounds over a 3-month period are expected in the groups of patients studied, while at the 800 micrograms dose there would be a net cost of 23-25 pounds. Sensitivity analysis showed that under many assumptions misoprostol is expected to be cost saving or cost neutral. [ABSTRACT FROM PUBLISHER]

OBJECTIVES: To examine the effect of socioeconomic status on the attitudes parents of preschool children towards child home safety issues and practice of home safety measures. SETTING: A community based study in the Lanarkshire Health Board area, a mixed urban-rural setting in central Scotland. METHODS: A postal survey of two random samples of parents of preschool children (aged 3 years). One sample (A) involved parents living in more affluent areas and the other (B) parents living in less affluent areas. RESULTS: In general, parents in both groups showed similar attitudes towards home safety. The only significant differences to emerge were over parental perceptions of the safety of the neighbourhood in which they lived and over the availability of money to keep their child safe (group B > group A, p < 0.0042). Parents from group B also tended to report similar or safer levels of home safety behaviour to parents from group A. CONCLUSIONS: The findings do not suggest that differences in the injury experience of children from more and less affluent backgrounds are due to differences in parental attitude, knowledge, or practice of home safety measures. Thus, the study does not support the selective targeting of families from less affluent areas with educational interventions. Instead, the findings do support the use of a multi-method approach to home safety, where educational approaches are complemented by environmental modification. [ABSTRACT FROM PUBLISHER]

A total of 139 patients with acute renal failure (ARF) were studied, of which 41 (29.4%) were elderly with mean age of 67.1 years and 98 (70.6%) were younger with mean age of 32.3 years. Surgical causes accounted for 65% of geriatric ARF while medical causes were predominant in the younger patients (55.1%). Amongst the surgical causes, prostate-related problems due to obstruction or following transurethral resection of prostate were seen in 20 patients (74%). Drugs and sepsis were the predominant causes of medical ARF in the geriatric patients (85.7%). Of all the causes of geriatric ARF, which included both medical and surgical, nephrotoxic drugs either alone or in combination with other predisposing factors were the cause in 22 (51%) patients. Haemodialysis was needed in 15 of geriatric (36.6%) and 64 of younger (65.3%) ARF patients. Recovery from ARF, as evidenced by normalization of serum creatinine, was delayed in the elderly as compared to the younger patients (32.0 versus 11.4 days, < 0.001). Mortality, though higher in the elderly as compared to the younger patients, was not significantly different (9.75% versus 6.1%). [ABSTRACT FROM PUBLISHER]
