Abstract
BACKGROUND Acute graft pyelonephritis (AGPN) is thought to affect graft and patient survival among renal transplant recipients. The objective was to compare outcomes among early AGPN (<6 months from transplant) versus late AGPN (>6 months from transplant). METHODS This retrospective study analysed 150 patients with AGPN dividing them into early and late AGPN from 2008 to 2016. Predictors of graft loss and mortality were compared using logistic regression analysis. Graft survival and patient survival were analysed using Kaplan-Meyer survival plots. RESULTS 55.3% (n = 83) had early AGPN and 44.7% (n = 67) had late AGPN. In an early AGPN group, 13.3% had CMV disease on the follow-up, compared to only 3% in the late AGPN group (p > 0.05). Furthermore, 38.6% had prolonged DJ stent in-situ (> 2 weeks) following transplant surgery in the early AGPN compared to only 19.4% in the late AGPN group (p < 0.05). Recurrent GPN was more common in the late AGPN group - (35.8% versus 18.1%). The presence of renal abscess was predictive of graft loss in Univariate analysis (HR-6.12, p < 0.004). There was decreased death-censored graft survival in the early AGPN group (p = 0.035), without a significant difference in the patient survival among the two groups. CONCLUSION The occurrence of early AGPN had a significant impact on long-term graft survival in renal transplant recipients, with no significant effect on patient survival. This study underlines the paramount importance of the prevention of urinary tract infection (UTI) in renal transplant recipients.

Abstract
INTRODUCTION Living kidney donation is a complex psychological experience for donors. The present study examined the psychosocial impact of kidney donation on donors. METHODS The retrospective study included 506 donors who donated a kidney between 2010 and 2018 at a transplant centre in India. These donors responded via a donor insight questionnaire about their hospital anxiety, and their possible level of depression. The information included socio-demographic form with multiple information. The health survey was used periodically evaluate the psychosocial impact among donors following donation, including the transplant outcomes. RESULTS The majority of donors were females (79.4%). There was a significant improvement in the quality of life among donors (SF-36) following the donation of a kidney, especially among those donors who maintained good graft functions themselves as well as those who were informed about good kidney function in transplanted recipients. These donors showed a lesser degree of depressive and anxiety scores (HAD score 3.5 and BDI II 4.8) than donors who had problems themselves and/or whose donated kidneys did not function well. Most living donors (89.1%) felt that the act of donation had a positive impact on their lives and those donors would encourage others to donate a kidney. Overall, the graft outcomes impacted the donor's state of mind. CONCLUSION The study showed a very positive impact of the acknowledgment of the donor by the recipient, especially those donors whose kidney transplants were well functioning. The state of depression, anxiety, and psycho-social outcomes correlated with the graft outcomes. Donors showed positive insight towards donation, with inner conscience still conclusively willing to donate and encourage others.

Abstract
INTRODUCTION The incidence of delayed gastric emptying (DGE) following oesophagogastrectomy with gastric conduit reconstruction is reported to be between 1.7% and 50%. This variation is due to differing practices of intraoperative pylorus drainage procedures, which increase the risk of postoperative biliary reflux and dumping syndrome, resulting in significant morbidity. The aim of our study was to establish rates of DGE in people undergoing oesophagogastrectomy without routine intraoperative drainage procedures, and to evaluate outcomes of postoperative endoscopically administered Botulinum toxin into the pylorus (EBP) for people with DGE resistant to systemic pharmacological treatment. METHODS All patients undergoing oesophagogastrectomy between 1 January 2016 and 31 March 2018 at our unit were included. No intraoperative pyloric drainage procedures were performed, and DGE resistant to systemic pharmacotherapy was managed with EBP. RESULTS Ninety-seven patients were included. Postoperatively, 29 patients (30%) were diagnosed with DGE resistant to pharmacotherapy. Of these, 16 (16.5%) were diagnosed within 30 days of surgery. The median pre-procedure nasogastric tube aspirate was 780ml; following EBP, this fell to 125ml (p<0.001). Median delay from surgery to EBP in this cohort was 13 days (IQR 7-16 days). Six patients required a second course of EBP, with 100% successful resolution of DGE before discharge. There were no procedural complications. CONCLUSIONS This is the largest series of patients without routine intraoperative drainage procedures. Only 30% of patients developed DGE resistant to pharmacotherapy, which was managed safely with EBP in the postoperative period, thus minimising the risk of biliary reflux in people who would otherwise be at risk following prophylactic pylorus drainage procedures.

Abstract
Background:ATI-450, is an investigational small molecule inhibitor of the MAPK-activated protein kinase 2 (MK2) signaling pathway. This pathway drives the expression of multiple cytokines including TNFα, IL-1α and β, and IL-6.Objectives:We evaluated the safety and tolerability of ATI-450 in healthy volunteers as well as pharmacokinetics (PK) and pharmacodynamics (PD). Here we present data from single and multiple ascending dose cohorts. The aim was to select a dose for evaluation in phase 2 in patients with rheumatoid arthritis.Methods:Safety, PK and PD were assessed in a randomized, observer-blind, placebo-controlled, phase 1 study in male and female healthy subjects aged 18-55 (n=77).Part A: Single Ascending Dose (SAD) (n=32, 8 subjects per dose cohort - 2 placebo, 6 active). A single dose of 10mg, 30mg, 50mg and 100mg was tested.Part B: Multiple Ascending Dose (MAD) (n=30, 10 subjects per dose cohort - 2 placebo, 8 active). 10mg BID, 30mg BID and 50mg BID doses were tested over 7 days of administration.Safety and tolerability of ATI-450 was evaluated based on adverse events, clinical laboratory, vital signs, 12-lead ECG, Holter monitoring, and physical examination. Blood was drawn for PK analysis at 0.5, 1, 2, 4, 6, 8, 12 hours, 24, 36, and 48 hours post dose in the SAD cohort and on day 7 of the MAD cohort. PD of ATI-450 were explored by investigating the inhibition of a target biomarker, phospho-HSP27 (pHSP27) and proinflammatory cytokines, TNFα, IL1β, IL6 and IL8 inex-vivoLPS-stimulated blood samples collected 4 and 12 hours post dose on day 7 from subjects in the MAD cohorts.Results:ATI-450 was generally well tolerated. No serious adverse events or severe adverse events were reported, and no adverse events led to discontinuation of the study medication. The most common adverse events (reported by 2 or more subjects who received ATI-450) observed during the trial were dizziness, headache, upper respiratory tract infection, constipation, nausea, and abdominal pain. All adverse events were mild. A trend of a decrease in absolute neutrophil count (ANC) was observed without correlated clinical sequelae.ATI-450 had dose proportional PK with a terminal half-life (t½) of 9-12 hours in the MAD cohort on day 7. A dose and concentration dependent inhibition ofex vivostimulated cytokines and target biomarker was observed. On day 7, patients in the 50mg BID dose (the dose with the highest degree of inhibition) recorded mean trough drug levels (12 hours post dose) that were 1.4, 2.5, 2.5 and 2.4 times greater than the IC80for TNFα, IL1β, IL8 and pHSP27 respectively. Mean Cmax drug levels (4 hours post dose) were 3.6, 6.4, 6.2 and 6.0 times greater than the IC80for TNFα, IL1β, IL8 and pHSP27 respectively. IL6 levels were inhibited by more than 50% for part of the dosing interval.Conclusion:Oral ATI-450 was generally well tolerated at all doses with dose proportional PK. The t½ suggests that once or twice daily oral dosing may be possible. At the 50mg BID dose, marked inhibition of TNFα, IL1β and IL8, IL6 and pHSP27 was observed. ATI-450 has the potential to be an oral, small molecule drug which can target multiple cytokines. Exploration of its benefit to risk profile in patients with rheumatoid arthritis is warranted.Disclosure of Interests:Judy Schnyder Shareholder of: aclaris therapeutics, Employee of: aclaris therapeutics, Joe Monahan Shareholder of: aclaris therapeutics, Employee of: aclaris therapeutics, Walter Smith Shareholder of: aclaris therapeutics, Employee of: aclaris therapeutics, Heidi Hope Shareholder of: aclaris therapeutics, Employee of: aclaris therapeutics, Deborah Kelly Shareholder of: aclaris therapeutics, Employee of: aclaris therapeutics, David Burt Shareholder of: aclaris therapeutics, Employee of: aclaris therapeutics, E Huff Shareholder of: aclaris therapeutics, Employee of: aclaris therapeutics, A Kaul Shareholder of: aclaris therapeutics, Employee of: aclaris therapeutics, A Hildebrand Shareholder of: aclaris therapeutics, Employee of: aclaris therapeutics, B Burnette Shareholder of: aclaris therapeutics, Employee of: aclaris therapeutics, N Klug Shareholder of: aclaris therapeutics, Employee of: aclaris therapeutics, M Bangs Shareholder of: Aclaris Therapeutics, Employee of: Aclaris Therapeutics, David Gordon Shareholder of: aclaris therapeutics, Employee of: aclaris therapeutics

Abstract
Abnormalities of chromosomes are an important and well documented cause of disorders of sexual development, fertility problems and congenital anomalies in mammals. Detection of low-level 63,X/64,XX mosaicism during routine cytogenetic evaluation is a challenge because its clinical significance is not yet fully clear. This study describes the prevalence and levels of 63,X mosaicism for a cohort of fertile mares and compares the results with eight problem mares for which no clinical cause of sub-fertility was found. The study design allowed for the analysis of micronuclei which are biomarkers of genomic instability and can disturb cell divisions, drive cancer development or cause congenital diseases. Although 27% of the fertile mares were identified to be 63,X mosaics, the results showed that the rates of abnormal cells were very low (1-3%). Levels of abnormal cells in problem mares with 63,X mosaicism were similar or higher. The average rate of micronuclei in the blood of the fertile mares was ∼1%, well below the baseline (5%) which was proposed for peripheral blood of normal healthy humans. We found weak to modest, but not significant, correlations between the age of fertile mares and 63,X cells (Kendall's tau b = 0.2905; p > 0.05) as well as the rate of micronuclei (Kendall's tau b = 0.1896; p > 0.05). Likewise, the correlation between presence of a 63,X cell line and micronuclei rate was not significant (Kendall's tau b = 0.3201; p > 0.05). The presence of 63,X cells in rates greater than 3% may indeed indicate a higher risk for sub-fertility and eventually for associated health problems in such mares. Detection and elimination of mares with high level of X aneuploidies from breeding may have a positive effect on the fertility within the general horse population. This data may support the evaluation of problem mares with mosaic karyotypes involving the X chromosome.

Abstract
More than 50% of patients with systemic lupus erythematosus (SLE) have renal involvement at presentation or during their illness. Lupus nephritis (LN) encompasses several patterns of renal disease, including glomerular, tubulointerstitial, and vascular pathologies. The presence and significance of renal vascular lesions (VLs) are often overlooked. VLs in LN are not rare with an incidence of 10%-40% on renal biopsies from various studies and their presence is often labeled as poor prognostic markers. The current treatment protocol for LN is mainly based on the glomerular pathology, and no guidelines/consensus exists for treatment of LN with VLs. We describe the clinical presentation, course, response to therapy, and outcomes in five patients with SLE with histological evidence of renal VLs.

Abstract
BACKGROUND Adults with cystic fibrosis (CF) have been reported to be at five to ten-fold risk (25 to 30 fold risk after solid organ transplant) of colorectal cancer (CRC) than the general population. Limited publications to date have reported on practical aspects of achieving adequate colonic cleanse producing good visualisation. In this study, we compared two bowel preparation regimens, standard bowel preparation and a modified CF bowel preparation. METHODS A non-randomised study of adults with CF attending a single centre, requiring colonoscopy investigation were selected. Between 2001 and 2015, 485 adults with CF attended the clinic; 70 adults with CF had an initial colonoscopy procedure. After five exclusions, standard bowel preparation was prescribed for 27 patients, and modified CF bowel preparation for 38 patients. Demographic and clinical data were collected for all consenting patients. RESULTS There was a significant difference between modified CF bowel preparation group and standard bowel preparation group in bowel visualisation outcomes, with the modified CF bowel preparation group having a higher proportion of "excellent/good" GI visualisation cleanse (50.0% versus 25.9%) and lower rates of "poor" visualisation cleanse (10.5% versus 44.5%) than standard bowel preparation (p = 0.006). Rates of "fair" GI cleanse visualisation were similar between the two groups (39.4% versus 29.6%) (Additional file 1: Table S1). Detection rates of adenomatous polyps at initial colonoscopy was higher in modified CF bowel preparation cohort than with standard preparation group (50.0% versus 18.5%, p < 0.01). Positive adenomatous polyp detection rate in patient's age > 40 years of age was higher (62.5%) than those < 40 years of age (24.3%) (p = 0.003). Colonic adenocarcinoma diagnosis was similar in both groups. CONCLUSION This study primarily highlights that standard colonoscopy bowel preparation is often inadequate in patients with CF, and that colonic lavage using modified CF bowel preparation is required to obtain good colonic visualisation. A higher rate of polyps in patients over 40 years of age (versus less than 40 years) was evident. These results support adults with CF considered for colonoscopy screening at 40 years of age, or prior to this if symptomatic; which is earlier than CRC screening in the non-CF Australian population.

Abstract
OBJECTIVES Systemic lupus erythematosus (SLE) is a chronic, multisystemic, immune-mediated disorder associated with a substantial hospitalization risk. As a comparatively rare disease, there is a sparsity of research examining the burden of hospital admission in the contemporary era. We aim to describe national trends in hospitalization rates in England between 1998 and 2015 for SLE, using rheumatoid arthritis (RA) and general population rates as comparison cohorts for benchmarking. METHODS Hospital admission rates, emergency and day-case admission rates, length of stay and bed days used were calculated using finished consultant episodes from Hospital Episode Statistics data. Cochran-Armitage tests and linear regression quantified the significance and magnitude of change over time. RESULTS SLE admissions increased from 8.97 to 9.04 per 100,000 (p < 0.001) between 1998 and 2015. By comparison, RA admissions rose from 71.0 to 171.6 per 100,000 (p < 0.001) and all-cause admissions rose from 24,500 to 34,500 per 100,000 (p < 0.001). Emergency admissions decreased both for SLE (2.6 to 1.2 per 100,000) and RA (12.8 to 4.4 per 100,000) despite all-cause emergency admissions increasing from 9400 to 10,300 per 100,000. SLE and RA day cases increased, whilst median length of stay decreased. Despite increasing admissions, total bed days for SLE and RA fell by 60% and 90%, respectively. CONCLUSIONS Whilst all-cause emergency admissions rose in the general population, those for SLE fell. Length of stay and bed days reduced and day cases increased, probably reflecting changing therapeutic strategies. This potentially large reduction in resource utilization warrants consideration when assessing the impact of new therapies.

Abstract
BACKGROUND With increasing graft survival, post-transplant immunoglobulin A nephropathy (IgAN) has emerged as an important cause of chronic graft dysfunction in renal allograft recipients. We studied the clinico-pathological features of post-transplant IgAN regardless of the primary disease. The aim was to study the usefulness of the Oxford classification in predicting survival. METHODS Indication graft biopsy specimens (n = 915) were received during a 10-year period; 27 biopsy specimens from 22 patients were diagnosed as IgAN. RESULTS Post-transplant IgAN was seen in 2.6% of biopsy specimens. Mean time to occurrence was 71.6 ± 47.6 months (range, 6.8 months to 16 years), occurring most commonly 4 to 8 years after transplant. Associated rejection was present in 4 biopsies; 72.7% (16/22), 91% (20/22), and 31.8% (7/22) presented with rise in serum creatinine, proteinuria, and hematuria, respectively. Four (21%) patients had nephrotic range proteinuria. Mesangial hypercelullarity (M1), endocapillary hypercelullarity (E1), segmental glomerulosclerosis (S1), and tubulo-interstitial fibrosis (T1-2) was present in 36.6%, 22.7%, 54.5%, and 31.8% biopsies, respectively. The most frequent Haas class was III (n = 7; 29.1%), followed by classes IV and I (n = 5; 20.8% each). The 2- and 5-year graft survival rates were 75% and 56%, respectively. High serum creatinine, low estimated glomerular filtration rate, E1 and T lesions, and degree of interstitial inflammation predicted graft survival. Interestingly, percentage (>25%) of segmentally sclerosed glomeruli and not S1 correlated with graft outcome. CONCLUSIONS The Oxford MEST scheme is useful in predicting graft survival in post-transplant IgAN. The degree of interstitial inflammation is also an important feature for determining graft outcomes in post-transplant IgAN.

Abstract
Despite kidney transplantation (KT) being considered as the best treatment modality for end-stage renal disease (ESRD), patient and graft survival in the elderly population is poorer than younger individuals. Many authors argue that prolonged life expectancy outweighs the risk of remaining on dialysis, but few studies had compared the treatment modalities, especially with peritoneal dialysis (PD). A retrospective study was conducted at a tertiary care institute to compare outcome of elderly ESRD patients, who received KT with those continued on PD; and to evaluate the predictors of patient survival. Patient survival at 1 year was (76.2% vs. 91.1%); 5 years (53.7% vs. 21.8%); and 10 years (35.6% vs. 0.00%) among KT and PD population, respectively. Infection was the most common cause of death among KT group (35 [41.2%] vs. 34 [28.2%]) while cardiovascular mortality in PD group (55 [46.2%] vs. 7 [8.2%]). Technique survival at 1, 5, and 10 years in PD group was 92.8%, 58.5%, and 0%, respectively. Similarly, graft survival at 1, 5, and 10 years in KT group was 98.7%, 90.2%, and 90.2%, respectively. Multivariate analysis showed body mass index (BMI) (hazard ratio [HR] 0.88, 95% confidence interval [CI] 0.82–0.93, p < 0.001), and albumin (HR 0.55, 95% CI 0.37–0.80, p = 0.002) were significant predictors of survival. In the 1st year, patient survival was better in PD than KT, but after adjustment for BMI and albumin, both short-term and long-term survival in elderly KT group was better than that of PD. Hence, elderly ESRD patients should not be barred from KT just because of age.

Abstract
Calcineurin inhibitors (CNIs) are the preferred drugs for treatment of childhood steroid-resistant nephrotic syndrome (SRNS) who are also resistant to cyclophosphamide (CYC). Although few studies have shown a benefit of one over the other, efficacy and safety of either CNIs (tacrolimus [TAC] or cyclosporine [CSA]) in this special population remained to be assessed in long-term studies. Forty-five children with SRNS who were also resistant to CYC (CYC-SRNS) from January 2006 to June 2011, were included in the study. Patients were treated with CNI either TAC or CSA based on 1:1 allocations and were prospectively observed. Patients who were nonresponsive to CNIs had been treated with mycophenolate mofetil. Outcomes were measured in terms of remission of NS, adverse effects of drugs, and progression of disease. After 6 months of treatment, 16/23 (69.5%) patients on CSA achieved remission and 18/22 (81.8%) on TAC achieved remission (P = 0.3). The side effects hypertrichosis, and gum hyperplasia were significantly less in TAC group as compared to CSA group (P < 0.001). The 1-, 2-, 3-, 4-, and 5-year estimated renal survival (doubling of serum creatinine as event) in CSA group was 96%, 91%, 85%, 54%, and 33% and in TAC group was 96%, 95%, 90%, 89%, and 79%, respectively (P = 0.02). Although TAC and CSA are equally efficacious, TAC has significantly less side effects. The long-term outcome of renal function was significantly better in patients who were treated with TAC as compared to CSA.

Abstract
This study was carried out to look for diagnostic and prognostic role of neutrophil gelatinase-associated lipocalin (NGAL) in early diabetic nephropathy (DN) in type 2 diabetes individuals. NGAL was measured in both urinary and serum sample of 144 type 2 diabetes individuals stratified into three categories based on urinary albumin-creatinine ratio and 54 control populations with estimated glomerular filtration rate >60 mL/min/1.73 m2 and serum creatinine <1.2 mg/dl. The serum NGAL (sNGAL), urine NGAL (uNGAL), and uNGAL/urine creatinine were significantly higher in diabetic individuals than in the control populations with significant difference in between the groups (P < 0.05). Difference of above values between control value and normoalbuminuria was also statistically significant (P < 0.05). Again, sNGAL and uNGAL correlate positively with albuminuria (P < 0.05). Tubular injury may precede glomerular injury in diabetic individuals, and NGAL can be used as a biomarker to diagnose DN even earlier to incipient nephropathy. Both sNGAL and uNGAL can predict albuminuria and be used as a noninvasive tool for diagnosis, staging, and progression of DN.

Abstract
Hepatitis C virus (HCV) infection in renal allograft recipient is associated with increased morbidity and mortality. At present, only few studies related to treatment and outcomes of HCV-infected renal allograft recipients with DAAs have been published. We aimed the study to assess the efficacy and safety of sofosbuvir-based regimens in HCV-infected renal allograft recipients. We analyzed data of 22 eligible HCV-infected renal allograft recipients (14 genotype-3, 6 genotype-1, one each genotype-2 and 4) who were treated with DAAs at our institute. DAA regimen included sofosbuvir and ribavirin with or without ledipasvir or daclatasvir for 12–24 weeks. Patients were followed up for 24 weeks after completion of treatment. A rapid viral response of 91%, end of therapy response of 100%, and sustained viral response at 12 and 24 weeks of 100% with rapid normalization of liver enzymes were observed. Therapy was well tolerated except for ribavirin-related anemia. A significant decrease in tacrolimus trough levels was observed and most patients required increase in tacrolimus dose during the study. Treatment with newer DAAs is effective and safe for the treatment of HCV-infected renal allograft recipients.

Abstract
Objective Evidences suggest that females with CKD are associated with high risk of maternal and fetal complications. Early referral in CKD with pregnancy for specialist care may prove useful for maternal and fetal outcome. Methods Study looked for assessment of impact of CKD detection at the time of pregnancy and its impact on fetal and maternal outcome. Results A total of 465 females were retrospectively evaluated for renal status during their pregnancies, 172 females were unaware about their renal illness at the time of pregnancy, while 208 females were under regular obstetrical and nephrological follow-up during their pregnancy. 44.1% of these females in both groups had GFR < 60 ml/min. Preeclampsia was observed in 17.6% of planned pregnancies, while it was observed in 47.5% of unplanned pregnancies. Worsening of renal failure during and following pregnancy was observed among all stages of CKD, and there was greater decline in GRF with progression to ESRD earlier during or after pregnancy among unplanned pregnancies. Planned pregnancy group had better fetal outcome. Low birth babies weighing < 2500 g in unplanned group were much higher than in planned pregnancies. Conclusions Chronic kidney disease is often clinically silent until renal impairment is advanced. Pregnancy can be a check point for detection of renal disease and managed appropriately for better maternal and fetal outcome.

Abstract
The growing epidemiological and economic burden of neurological diseases on society is tremendous. A correct and timely diagnosis can help in lowering the burden and improving the life quality of both the diseased person and the caretaker. Imaging of the brain (neuroimaging) using CT, MRI, and nuclear imaging methods can provide anatomical and functional information. Neuroreceptors are central to neurotransmission and neuromodulation in the CNS. In vivo imaging of receptors in the brain provides powerful tools for the functional study of the central nervous system (CNS) in normal or diseased states. Presently, PET imaging using non-metallic radiotracers dominates the imaging of neuroreceptors. Metal-based probes for SPECT and PET can be economical and logistically easier to use without compromising the information. This review focuses on the development of metallic radiotracers for (99mTc) SPECT and (68Ga) PET along with future directions based on the metallic probes developed for other imaging modalities namely MRI.

Abstract
BACKGROUND Barrett's oesophagus is a precursor to the development of oesophageal adenocarcinoma. This study sought to clarify the role of genetic, chromosomal and proliferation biomarkers that have been the subjects of multiple studies through meta-analysis. METHODS MEDLINE, Embase, PubMed and the Cochrane Library were searched for clinical studies assessing the value of p53, p16, Ki-67 and DNA content abnormalities in Barrett's oesophagus. The main outcome measure was the risk of development of high-grade dysplasia (HGD) or oesophageal adenocarcinoma. RESULTS Some 102 studies, with 12 353 samples, were identified. Mutation (diagnostic odds ratio (DOR) 10·91, sensitivity 47 per cent, specificity 92 per cent, positive likelihood ratio (PLR) 4·71, negative likelihood ratio (NLR) 0·65, area under the curve (AUC) 0·792) and loss (DOR 16·16, sensitivity 31 per cent, specificity 98 per cent, PLR 6·66, NLR 0·41, AUC 0·923) of p53 were found to be superior to the other p53 abnormalities (loss of heterozygosity (LOH) and overexpression). Ki-67 had high sensitivity in identifying high-risk patients (DOR 5·54, sensitivity 82 per cent, specificity 48 per cent, PLR 1·59, NLR 0·42, AUC 0·761). Aneuploidy (DOR 12·08, sensitivity 53 per cent, specificity 87 per cent, PLR 4·26, NLR 0·42, AUC 0·846), tetraploidy (DOR 5·87, sensitivity 46 per cent, specificity 85 per cent, PLR 3·47, NLR 0·65, AUC 0·793) and loss of Y chromosome (DOR 9·23, sensitivity 68 per cent, specificity 80 per cent, PLR 2·67, NLR 0·49, AUC 0·807) also predicted malignant development, but p16 aberrations (hypermethylation, LOH, mutation and loss) failed to demonstrate any advantage over the other biomarkers studied. CONCLUSION Loss and mutation of p53, and raised level of Ki-67 predicted malignant progression in Barrett's oesophagus.

Abstract
The optimal time for dialysis initiation remains controversial. Studies have failed to show better outcomes with early initiation of hemodialysis; even a few had shown increased adverse outcomes including poorer survival. Few studies have examined the same in patients on peritoneal dialysis (PD). Measured glomerular filtration rate (mGFR) not creatinine-based estimated GFR is recommended as the measure of kidney function in end-stage renal disease (ESRD) patients. The objective of this observational study was to compare the outcomes of Indian patients initiated on PD with different residual renal function (RRF) as measured by 24-h urinary clearance method. A total of 352 incident patients starting on chronic ambulatory PD as the first modality of renal replacement therapy were followed prospectively. Patients were categorized into three groups as per mGFR at the initiation of PD (≤5, >5–10, and >10 ml/min/1.73 m2). Patient survival and technique survival were compared among the three groups. Patients with GFR of ≤5 ml/min/1.73 m2 (hazard ratio [HR] - 3.42, 95% confidence interval [CI] - 1.85–6.30, P = 0.000) and >5–10 ml/min/1.73 m2 (HR - 2.16, 95% CI - 1.26–3.71, P = 0.005) had higher risk of mortality as compared to those with GFR of >10 ml/min/1.73 m2. Each increment of 1 ml/min/1.73 m2 in baseline GFR was associated with 10% reduced risk of death (HR - 0.90, 95% CI - 0.85–0.96, P = 0.002). Technique survival was poor in those with an initial mGFR of ≤5 ml/min/1.73 m2 as compared to other categories. RRF at the initiation was also an important factor predicting nutritional status at 1 year of follow-up. To conclude, initiation of PD at a lower baseline mGFR is associated with poorer patient and technique survival in Indian ESRD patients.

Abstract
It is well known that exposures like those from (226)Ra, (224)Ra and Thorotrast(®) injections increase the risk of neoplasia in bone marrow and liver. The thorium-based radioactive contrast agent Thorotrast(®) was introduced in 1929 and applied worldwide until the 1950s, especially in angiography and arteriography. Due to the extremely long half-life of several hundred years and the life-long retention of the thorium dioxide particles in the human body, patients suffer lifetime internal exposure. The health effects from the incorporated thorium were investigated in a few cohort studies with a German study being the largest among them. This retrospective cohort study was set up in 1968 with a follow-up until 2004. The study comprises 2326 Thorotrast patients and 1890 patients of a matched control group. For those being alive at the start of the study in 1968 follow-up was done by clinical examinations on a biannual basis. For the others, causes of death were collected in various ways. Additionally, clinical, radiological and biophysical studies of patients were conducted and large efforts were made to best estimate the radiation doses associated with incorporation of the Thorotrast. The aim of this paper is to describe the cohort, important results and some open questions. The data from the German Thorotrast Study are available to other interested researchers.

Abstract
Seronegative Invasive Gastro-intestinal cytomegalovirus disease in renal allograft recipients Background -CMV as oppurtunistic infection affecting the gastrointerstinal tract is the most common cause for tissue invasive CMV disease occuring in 10-30% of organ transplant recepients. Gastrointerstinal CMV disease can be diagnosed in presence of clinical suspecion along with histopathological findings (CMV inclusions) and presence of mucosal lesion(s) on endoscopic examination with collaborative evidences via molecular technique. Aims-Few cases of CMV infection affecting the gastrointerstinal tract show no evidences of dissemintion despite use of highly sensitive molecular techniques. We encountered 6 cases where in despite strong clinical suspecion of Gastrointerstinal CMV disease there were seronegative and endoscopic negative evidences for CMV, blind tissue biopsy yeilded positive results for CMV disease with excellent improvement with antiviral therapy. Conclusions-Blind biopsy specimen for tissue PCR could serve as saviour in an immunocompromised individiual who has a strong clinical symptomatology for GI-CMV disease in absence of viremia, normal endoscopy and histopathology, so that the early therapeutic interventions could help in excellent patient and graft survival.

Abstract
We undertook this study to compare subjective global assessment (SGA) and nutrition risk index (NRI) as malnutrition screening tools in peritoneal dialysis (PD) patients. Nutrition status of the patients was categorized into low, moderate and high risk of malnutrition based on both NRI and SGA. The sensitivity, specificity and predictive values of NRI were compared with SGA, an already validated tool of nutrition status assessment in PD patients. Two hundred and eighty-three end-stage renal disease patients (age 50.02 ± 13.76 years; 204 males, 150 diabetic) were included. Based on SGA, 71/283 (25.08%) had normal nutrition, 192/283 (67.84%) mild-moderate and 20/283 (7.07%) severe malnutrition. Based on NRI, 38/283 (13.43%) patients had normal nutritional status, 193/283 (68.20%) mild-moderate and 52/283 (18.37%) severe malnutrition. Twenty-three of 283 (8.1%) were correctly classified as normal by NRI (true negative) and 197/283 (69.6%) as malnourished (true positive), 15/283 (5.3%) as false negative, 48/283 (16.96%) were misclassified as malnourished (false positive). NRI has sensitivity of 92.9% and specificity of 32.39%. Positive predictive value and Negative predictive values (NPVs) of NRI are 80.41% and 60.53%, respectively. Accuracy of the test is 78%. The receiver operating characteristic curve of NRI is 0.63. To conclude, NRI carries high sensitivity but low specificity as compared to SGA. It can be used as screening tool but not as a diagnostic tool for assessment of nutritional status in PD patients because of its low specificity and NPV.

Abstract
Anti-glomerular basement membrane (anti-GBM) disease is an autoimmune disease that most commonly presents as rapidly progressive glomerulonephritis with or without pulmonary involvement. It is characterized by the presence of antibodies directed to antigenic targets within glomerular and alveolar basement membranes. This study was performed to evaluate the clinicopathological features and outcome in anti-GBM crescentic glomerulonephritis (CrGN) at a tertiary care center in North India over a period of 9 years (January 2004 to December 2012). A diagnosis of anti-GBM CrGN was made in the presence of >50% crescents, linear deposits of IgG along GBM, and raised serum anti-GBM antibody titer. Of 215 cases of CrGN diagnosed during this period, 11 had anti-GBM CrGN. Anti-GBM CrGN was found at all ages but was most common in the third to fifth decade with no gender predilection (mean age 48 +/- 15 years, 13–67 years). Patients presented with a mean serum creatinine of 10.2 +/- 5.3 mg/dl and sub-nephrotic proteinuria. Pulmonary involvement was present in two patients. Myeloperoxidase-antineutrophil cytoplasmic antibody was positive in two (2/11) elderly patients. Follow-up was available in four patients for a range of 30-270 (mean 99.5 ± 114.5) days, two remained dialysis dependent while two died due to uremia and sepsis. Our findings show that anti-GBM disease is a rare cause of CrGN in India, accounting for only 5% of patients. It usually presents as a renal-limited disease and is associated with a poor renal outcome.

Abstract
Chronic kidney diseases (CKD) adversely affects fetal and maternal outcomes during pregnancy. We retrospectively reviewed the renal, maternal and fetal outcomes of 51 pregnancies in women with CKD between July 2009 and January 2012. Of the 51 subjects (mean age 27.8 ± 7.04), 32 had 19 had estimated glomerular filtration rate (eGFR) <60 ml/min. There was significantly greater decline in eGFR at 6 weeks (55.8 ± 32.7 ml/min) after delivery as compared to values at conception (71.7 ± 27.6 [P < 0.001]). The average decline of GFR after 6 weeks of delivery was faster in patients with GFR < 60 ml/min/1.73 m(2) at -18.8 ml/min (stage 3, n = 13, -20.2 ml/min; stage 4, n = 6, -15.8 ml/min) as compared to -15.1 ml/min in patients with GFR ≥ 60 ml/min/1.73 m(2). Three of the six patients (50%) in stage 4 CKD were started on dialysis as compared to none in earlier stages of CKD (P = 0.002). At the end of 1 year, all patients in stage 4 were dialysis dependent, while only 2/13 in stage 3 were dialysis dependent (Odds ratio 59.8, 95% confidence interval 2.8-302, P = 0.001). Preeclampsia (PE) was seen in 17.6%. Only 2/32 (6.25%) patients with GFR ≥ 60 ml/min/1.73 m(2) developed PE while 7/19 (36.84%) patients with GFR < 60 ml/min developed PE. Of the 51 pregnancies, 15 ended in stillbirth and 36 delivered live births. Eleven (21.56%) live-born infants were delivered preterm and 7 (13.72%) weighed < 2,500 g. The full-term normal delivery was significantly high (50%) in patients with GFR ≥ 60 ml/min/1.73 m(2) (P = 0.006) and stillbirth was significantly high - 9/19 (47.36%) patients with GFR < 60 ml/min/1.73 m(2). To conclude, women with CKD stage 3 and 4 are at greater risk of decline in GFR, PE and adverse maternal and fetal outcomes as compared to women with earlier stages of CKD.

Abstract
Immunoglobulin A (IgA) dominant membranoproliferative glomerulonephritis (MPGN) is rare, described only as case reports. We report a rare case of an elderly man presenting with rapidly progressive renal failure and nephrotic range proteinuria with histological, immunofluorescence, and ultrastructural findings supporting a diagnosis of IgA dominant MPGN. Autoimmune disease, cryoglobulinemia and infection-associated glomerulonephritis were excluded. Remission was achieved within 3 months of treatment. This case highlights an uncommon diagnosis with a good response to therapy. The differential diagnosis of IgA nephropathy with MPGN-like pattern is discussed.

Abstract
Pregnancy-associated acute kidney injury (PAKI) is encountered frequently in developing countries. We evaluated the maternal, fetal and renal outcomes in women with PAKI who needed at least one session of dialysis. Of the total of 98 cases (mean age 28.85 ± 5.13 years; mean parity 2.65 ± 1.28) of PAKI, the most common cause of PAKI was postabortal sepsis. Eighteen patients died; those with oligoanuria, sepsis and central nervous system (CNS) involvement were at greater risk of mortality. The relative risk (RR) of neonatal mortality was lower after with full-term delivery (RR: 0.17, 95% confidence interval (CI): 0.03-0.96, P = 0.02) compared to preterm delivery. Of the 80 surviving patients, 60 (75%) patients achieved complete recovery of renal function at the end of 3 months; and of the remaining 14 had presumed (n = 4) or, biopsy-proven (n = 10) acute patchy cortical necrosis. The RR of non-recovery of renal function was high (RR: 24.7, 95% CI: 3.4- 179.5) in patients who did not recover at 6 weeks. Of the 14 patients with cortical necrosis, 3 (21.42%) became independent of dialysis at 6 months. PAKI patients should be watched for dialysis independency for 6 months.

Abstract
BACKGROUND Cryptosporidium is one of the common causes of infective diarrhea in post-transplant patients in endemic areas. However, data are limited on Cryptosporidium infection in recipients of solid organ transplantation. The aim of this study was to determine the incidence, disease manifestation, management, and outcome of Cryptosporidium infection in living-donor renal transplant recipients (RTR). METHODS We performed a detailed retrospective review of the data on all RTR who had diarrheal illness requiring evaluation and hospitalization, and Cryptosporidium infection. RESULTS During the study period, 119/1235 (8.98%) RTR developed diarrhea, and Cryptosporidium was found in 34/119 (28.5%). Nine of 680 (1.3%) patients were on a cyclosporine (CSA)-based regimen, and 25/643 (3.8%) patients were on a tacrolimus (Tac)-based regimen. The relative risk of developing Cryptosporidium infection was lower on the CSA-based regimen, compared with the Tac-based regimen (odds ratio [OR]: 0.35, 95% confidence interval [CI]: 0.17-0.72, P = 0.003). Twelve of the 34 patients had acute graft dysfunction, mainly caused by combined Tac toxicity and dehydration. Mean serum creatinine and trough Tac level were 2.04 ± 0.65 mg/dL and 8.24 ± 1.19 ng/dL, respectively. Nitazoxanide alone was used in 13 patients, and nitazoxanide in combination with fluoroquinolone in 21 patients, with duration of treatment ranging from 16 to 60 days. Tac was changed to CSA in 8/11 patients. The clearance of cysts and response to nitazoxanide alone were significantly lower, compared with combination therapy (61.53% vs. 95.23%, P = 0.01, 38.46 vs. 85.71%, P = 0.004, respectively). The OR for cyst clearance and response was also significantly lower with nitazoxanide alone, in comparison with combination therapy (OR: 0.65, 95% CI: 0.34-0.92, P = 0.01, OR: 0.45, 95% CI: 0.21-0.81, respectively). Four (16%) of 24 patients with response had relapse. CONCLUSION Patients with Tac and mycophenolate mofetil combination therapy had a significantly high risk of Cryptosporidium infection. Cryptosporidial infection may require prolonged nitazoxanide therapy, either alone or in combination, with or without reduction in immunosuppression.
