Abstract
Background and objective Membranous glomerulonephritis (MGN) is a common cause of adult nephrotic syndrome. Tumor necrosis factor-α (TNF-α) is a proinflammatory cytokine that signals by attaching to TNF receptors. TNF-α plays a pivotal role in the development and progression of different forms of glomerulonephritis. Several research findings suggest that TNF-α receptors (TNFR1 and TNFR2) are predictors of estimated glomerular filtration rate (eGFR) decline. In light of this, this study aimed to explore the relationship between TNFR2 and eGFR, as well as the predictive role of TNFR2 in eGFR decline in MGN. Methods A total of 50 consecutive patients with a diagnosis of primary MGN based on renal biopsies and clinical workups were included in the study. TNFR2 levels in serum, urine, and gene expression were evaluated at baseline and after three months of follow-up by using enzyme-linked immunosorbent assay (ELISA) kits for TNFR2 (KTE60215, Abbkine, Wuhan, China). Cox regression was employed to determine the predictive significance of TNFR2 in persistent eGFR decline. Additionally, an ROC curve analysis was conducted to assess the prognostic value of TNFR2 in predicting persistent eGFR decline among MGN patients. Results We assessed the levels of inflammatory markers TNF-α and TNFR2, examined their correlation with eGFR and renal injury, and investigated their potential in predicting persistent eGFR. Patients with MGN exhibited elevated levels of TNFR2 in their serum, urine, and gene expression compared to healthy individuals. Additionally, there was a positive correlation between serum TNFR2 and TNF-α, urine protein-creatinine ratio (UPCR), uric acid, and total cholesterol. Conversely, there was a negative correlation with eGFR, serum albumin, and calcium. Serum TNFR2 showed statistical significance in a univariate Cox regression analysis (HR: 1.010, 95% CI: 1.00-1.01, p = 0.045) for predicting a persistent decline in eGFR. However, it did not show significance concerning relapse and remission. An ROC curve was created to assess TNFR2's prognostic potential as a biomarker, demonstrating an AUC of 0.683, with a sensitivity of 68% and specificity of 64%. Conclusions Based on our findings, TNFR2 is a predictive biomarker for eGFR decline in MGN, correlating with renal inflammation and predicting deterioration in renal function. TNFR2 emerges as a promising biomarker for early identification in patients at risk of renal function decline.

Abstract
BACKGROUND The presence of microvascular inflammation (MVI) characterized by leukocyte margination in the glomeruli (glomerulitis, Banff score 'g') and peritubular capillaries (peritubular capillaritis, Banff score 'ptc') is a hallmark histological feature of antibody-mediated rejection (AMR), even in the absence of circumferential C4d positivity. In this study, we assessed the efficacy of pre-transplant plasma cytokines as an ancillary screening tool to identify MVI in kidney allograft indication biopsies to facilitate better graft survival. METHOD This single-center prospective analytical study comprises 38 kidney transplant recipients whose peripheral blood was collected before transplant and assessed for the plasma cytokine concentrations of FOXP3, IL-6, TGF beta, and IL-17 using enzyme-linked immunosorbent assays (ELISA). Histopathological assessment was done in post-transplant indication biopsies, and Banff scores of 'g+ ptc' were calculated to categorize recipients into three MVI groups. The correlational, regression, and ROC curve analyses were used to assess the association and predictive ability of the cytokines with respect to MVI. RESULTS In our study cohort, 27 recipients had MVI=0, five had MVI=1, and six had MVI≥2. A significant difference in plasma cytokines was observed between these groups, and we found a strong negative correlation of FOXP3 with MVI, whereas a strong positive correlation of IL-6, TGF beta, and IL-17 was recorded with MVI. We have also assessed the predictive ability of these cytokines, FOXP3, IL-6, TGF-beta, and IL-17, through the ROC curve, which showed an AUC of 0.70, 0.76, 0.84, and 0.72, respectively. CONCLUSION Our findings suggest that the pre-transplant levels of cytokines FOXP3, IL-6, TGF-beta, and IL-17 could be measured to identify recipients at risk of post-transplant MVI, which could further serve as an additional tool for effective management of the kidney allograft.

Abstract
The incidence of acute kidney injury (AKI) has increased in the recent past. Patients with AKI have an increased risk of mortality. They are also at increased risk of developing chronic kidney disease (CKD). AKI can lead to irreversible loss of renal function despite complete clinical recovery. Currently, no tools are available to diagnose this subclinical loss of renal function. Renal functional reserve (RFR) can serve as an essential tool for analyzing this subclinical loss of renal function, and patients with loss of RFR post-AKI may be closely followed for the development of CKD. This prospective observational study, conducted at the Department of Nephrology, Jawaharlal Institute of Postgraduate Medical Education & Research (JIPMER), aimed to investigate RFR in 223 patients with AKI requiring dialysis. The study excluded patients with CKD and obstructive uropathy. Methods included RFR assessment three months post-AKI recovery, utilizing technetium-99m (Tc-99m) diethylenetriaminepentaacetic acid (DTPA) plasma clearance during amino acid infusion. Statistical analyses and logistic regression were applied, receiving ethical approval. Results revealed a high in-hospital mortality rate of 78.02%, associated with elevated Sequential Organ Failure Assessment (SOFA) scores. Among 24 patients with complete AKI recovery, the RFR at three months was 10.06% (interquartile range (IQR) 5.60-20.15), with the measured GFR significantly lower than the estimated glomerular filtration rate (GFR). The study concludes that AKI requiring dialysis is linked to high mortality and emphasizes the predictive value of SOFA scores. Additionally, RFR testing at three months post-recovery provides insights into potential long-term impacts on renal function. This study contributes valuable insights into the prognosis of AKI patients requiring dialysis. It underscores the need for further research on RFR as a diagnostic tool and the lasting consequences of AKI.

Abstract
We report an incident case of herpetic keratitis in a renal transplant recipient treated for acute renal allograft rejection. A lady in her forties, a renal transplant recipient on treatment for allograft rejection, was referred with mild ocular symptoms in the right eye for two days. On evaluation, she had mild conjunctival hyperemia and extensive herpetic epithelial keratitis involving the limbal and central corneas. The patient healed without sequelae from the antivirals and lubricants. Viral keratitis in immunosuppressed patients should be suspected, even in patients with mild symptoms, as early initiation of treatment can prevent rapid stromal involvement and scarring.

Abstract
OBJECTIVE To assess the impact of maternal near-miss on late maternal death and the prevalence of hypertension or chronic kidney disease (CKD) and mental health problems at 12 months of follow up. METHODS This prospective cohort study was conducted in a tertiary hospital in the southeastern region of India from May 2018 to August 2019, enrolling those with maternal near-miss and with follow up for 12 months. The primary outcomes were incidence of late maternal deaths and prevalence of hypertension and CKD during follow up. RESULTS Incidence of maternal near miss was 6.7 per 1000 live births. Among those who had a near miss, late maternal deaths occurred in 7.2% (95% confidence interval [CI] 3.1%-11.3%); prevalence of CKD was 23.0% (95% CI 16.2%-29.8%), and of hypertension was 56.2% (95% CI 50.5%-66.5%) and only two women had depression on follow up. After adjusting for age, parity, socioeconomic status, gestational age at delivery, hemoglobin levels, and perinatal loss, only serum creatinine was independently associated with late maternal death and CKD on follow up. CONCLUSIONS Women who survive a life-threatening complication during pregnancy and childbirth are at increased risk of mortality and one or more long-term sequelae contributing to the non-communicable disease burden. A policy shift to increase postpartum follow-up duration, following a high-risk targeted approach after a near-miss event, is needed.

Abstract
OBJECTIVES Patients with diabetes have a higher risk of developing chronic kidney disease (CKD). Early detection of CKD through microalbuminuria screening, followed by treatment, delays the progression of CKD. We evaluated the cost-effectiveness of population-based screening of microalbuminuria among normotensive type 2 diabetes mellitus patients aged >40 years compared with no screening scenario using a decision tree combined with the Markov model. METHODS We considered two scenarios: Scenario I - dipstick microalbuminuria followed by spot-urine albumin-creatinine ratio (ACR) and serum creatinine in sequence; Scenario II - spot urine ACR plus serum creatinine. A mathematical cohort of the target population was simulated over a lifetime horizon with an annual cycle. Data for the model were obtained from secondary resources. The incremental cost-effectiveness ratios (ICERs) were estimated for screening scenarios compared to nonscreening scenario, along with sensitivity analyses. RESULTS The discounted ICER per quality-adjusted life years gained for annual microalbuminuria screening in the normotensive diabetic population in India were ₹ 24,114 (US$ 308) and ₹ 13,790 (US$ 176) for scenarios I and II, respectively. Annual screening by scenarios I and II resulted in a reduction of 180 and 193 end-stage renal disease (ESRD) cases per 100,000 population, respectively, resulting in a cost saving of ₹ 12.3 and 13.3 Crore spent on ESRD management over 10 years. Both scenarios were also cost-effective even at the screening frequencies of 5 and 10 yearly. CONCLUSION Microalbuminuria screening was cost-effective at the threshold of one-time GDP per capita in India.

Abstract
BACKGROUND Sub-clinical inflammation in hyperglycemia is tied to the pathogenesis of diabetic kidney disease (DKD). Though well known for its immunostimulatory function, the significance of extracellular heat shock protein 72 (eHSP72) in DKD is not well studied. We aimed to determine the association of extracellular HSP72 with systemic inflammation and the progression of DKD, and explore its possible clinical significance in DKD. METHODS 160 type 2 diabetic individuals were enrolled in the study. Their anthropometric data, routine biochemical parameters, urinary renal function parameters, and blood count parameters were estimated. Plasma from patients' blood samples were used to estimate HSP72 and interleukin 1β (IL-1β) using sandwich immunoassays. RESULTS Plasma eHSP72 is elevated in DKD. Pairwise comparisons showed the drastic elevation of eHSP72 in the presence of albuminuria. A significant positive relationship was observed between plasma levels of eHSP72 and IL-1β. eHSP72 levels did not statistically differ between micro and macro-albuminuric DKD. However, it was inversely associated with estimated glomerular filtration rate, the index of disease severity, independent of age, gender, diabetes duration and absolute monocyte count. At a cutoff of 0.52 ng/ml, with sensitivity of 64.1 % and specificity of 69.2 %, plasma eHSP72 differentiated the presence of DKD in type 2 diabetics with statistical significance. CONCLUSION The positive relationship of eHSP72 and IL-1β with worsening DKD likely indicates their participation in immunostimulatory pathways of renal fibrosis. eHSP72 may be closely linked to albuminuria-induced tubular injury and likely contributes to fibrotic changes in the progression of DKD. From our study, we infer the possible clinical significance of eHSP72 as a marker of sub-clinical renal damage in DKD, and the implication of IL-1β-associated mechanisms in DKD progression.

Abstract
Introduction Chitotriosidase-1 (CHIT-1) is a marker of macrophage activation and recently attributed to type 2 diabetes mellitus (T2DM). However, its role in the development and progression of diabetic kidney disease (DKD) has been sparsely discussed in the recent literature. Materials and Methods In this cross-sectional exploratory study, 81 participants with T2DM were classified into two groups based on the presence of DKD. Their anthropometric, biochemical, and pathological profiles were estimated. Circulatory CHIT-1 concentration was determined using the enzyme-linked immuno-sorbent assay (ELISA) in plasma. Results CHIT-1 was significantly elevated in diabetic nephropathy, independent of age and gender. It is associated with severity of kidney disease, as assessed using urinary protein-creatinine ratio (uPCR) in a multiple linear regression model, independent of age, gender, diabetes duration, and insulin resistance. CHIT-1 positively predicted the likelihood of DKD in the study population (area under the curve = 0.724, P < 0.05). The duration of diabetes correlated positively with uPCR and negatively with estimated glomerular-filtration rate. Neutrophil-Lymphocyte ratio was elevated in participants with DKD. This well-established marker of systemic inflammation exhibited significant positive association with CHIT-1. Conclusion Plasma CHIT-1 protein is elevated in DKD and associated with disease progression. It is capable of reflecting disease severity and is closely related to systemic inflammation possibly caused by pro-inflammatory circulatory immune cells.

Abstract
Patients with chronic kidney disease (CKD) are at a higher risk of cognitive impairment. Poor quality of life and decreased compliance are frequently observed with cognitive decline among CKD patients. Cognitive impairment among Stage 5 CKD patients varies with different modalities of treatment, and contradicting results have been reported. Fifty-four medically stable Stage 5 CKD patients undergoing different modalities of treatment were recruited: Patients with Stage 5 CKD on maintenance hemodialysis (HD) (n = 18), continuous ambulatory peritoneal dialysis (CAPD) (n = 18), and conservative management (CM) (n = 18). Eighteen apparently healthy participants were recruited as a control group. The cognitive functions assessed were P300 event- related potential, auditory and visual reaction times (VRTs). Kidney function was assessed by serum creatinine and estimated glomerular filtration rate. Creatinine levels were significantly higher in all three treatment groups compared with the control group. Multivariate analysis revealed a significant association between the CKD groups (n = 54) and the parameters of cognitive function. P300 latency was prolonged in all treatment groups compared with the control group and was significantly prolonged in patients on CM compared with HD and CAPD patients. The VRT of CM patients was found to be significantly higher compared with the control group. The auditory reaction time was significantly prolonged in all treatment groups compared with the control group and in the CM group compared with the CAPD group. Cognitive function was more affected in Stage 5 CKD patients on CM compared with patients undergoing HD or CAPD.

Abstract
OBJECTIVES Tacrolimus, an important constituent of the immunosuppressant regimen for renal transplant recipients, can result in posttransplant diabetes mellitus. The adverse effect profile of tacrolimus is yet to be completely understood. The relationship between the blood level of tacrolimus and development of posttransplant diabetes mellitus has not been clearly elucidated in Indian populations. We conducted this study to investigate the frequency of posttransplant diabetes mellitus and other adverse effects of tacrolimus, to enumerate the risk factors associated with posttransplant diabetes mellitus development, and to correlate the blood levels of tacrolimus with its occurrence. MATERIALS AND METHODS This prospective observational study included 77 renal transplant patients receiving tacrolimus. The blood sugar levels (fasting and postprandial) were monitored, and patients were asked regularly about the adverse effects of tacrolimus experienced by them for 6 months posttransplant. Trough levels of tacrolimus in blood were correlated with occurrence of posttransplant diabetes mellitus. RESULTS Posttransplant diabetes mellitus developed in 62.3% (48/77) of renal transplant recipients on a tacrolimus-based regimen. Other adverse effects observed included tremors, diarrhea, alopecia, cyto- megalovirus infection, headache, biopsy-proven calci- neurin inhibitor nephrotoxicity, peripheral neuropathy, and BK virus infection. Higher tacrolimus trough level at month 1 posttransplant was significantly associated with the development of posttransplant diabetes mellitus (adjusted odds ratio = 1.379; 95% CI, 1.02-1.86). The best cutoff of tacrolimus trough level at month 1 posttransplant to reduce the risk of posttransplant diabetes mellitus was 8.1 ng/mL. There was a 5 times increased risk of developing posttransplant diabetes mellitus when tacrolimus trough level at month 1 posttransplant was >8.1 ng/mL (adjusted odds ratio = 5.4; 95% CI, 1.4-19.9). CONCLUSIONS Posttransplant diabetes mellitus is a common adverse effect of tacrolimus among renal transplant recipients. A trough level >8.1 ng/mL at month 1 posttransplant was an important predictor for posttransplant diabetes mellitus.

Abstract
Introduction Angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARB) are the antihypertensive drug class of choice in patients with chronic kidney disease (CKD). Head-to-head comparisons of the renal or non-renal outcomes between ACEI/ARB users and nonusers have not been conducted in all population groups. We examined the renal and cardiovascular outcomes in users and nonusers enrolled in the Indian Chronic Kidney Disease (ICKD) Study. Methods A total of 4,056 patients with mild-moderate CKD were studied. Patients were categorized as ACEI/ARB users or nonusers. Major adverse kidney events [ESKD (end stage kidney disease), ≥50% decline in eGFR and kidney death], all-cause mortality, and cardiovascular mortality were analyzed over a median follow-up period of 2.64 (1.40, 3.89) years between the two groups. Results Out of a total of 4,056 patients, 3,487 (87%) were hypertensive. The adjusted sub-hazard ratio (SHR) and 95 % CI for ACEI /ARB users was 0.85 (0.71, 1.02) for MAKE, 0.80 (0.64, 0.99) for a 50% decline in eGFR, and 0.72 (0.58, 0.90) for ESKD. For cardiovascular mortality, ACEI/ARB users were at lower risk (SHR = 0.55, 95% CI: 0.34, 0.88). Diuretic users were at increased risk of all-cause mortality (HR = 1.95, 95% CI: 1.50, 2.53) and cardiovascular mortality (adjusted SHR = 1.73, 95% CI: 1.09, 2.73). There was non-significant association between the use of other antihypertensives and any of the end points. Discussion ACEI/ARB use is associated with slower rate of decline in eGFR in those with CKD stage 1-3. ACEI/ARB users had a significantly lower risk of renal outcomes, and cardiovascular mortality.

Abstract
Abstract
Objectives The idiopathic group is a significant cause of chronic kidney disease (CKD) in developing countries. Literature available on ocular surface changes has predominantly been reported in patients undergoing hemodialysis. Little is known about the changes in patients undergoing peritoneal dialysis. The present study aimed to identify ocular surface changes in an idiopathic group of CKD undergoing dialysis.
Aim To compare tear film disorders and the severity of ocular surface changes (goblet cell density, squamous metaplasia, and corneoconjunctival calcification) in patients of idiopathic etiology with CKD undergoing hemodialysis and peritoneal dialysis. This is an analytical study.
Materials and Methods Asymptomatic adult patients of idiopathic CKD, on treatment with dialysis underwent comprehensive ophthalmic examination, including best-corrected visual acuity, slit-lamp examination, and a dilated fundus examination. Dry eye assessment was done by ocular surface staining score, Schirmer test, and tear breakup time (TBUT). Conjunctival impression cytology was studied to assess changes on ocular surface. Chest X-rays for aortic calcification were reviewed and data analyzed.
Results Both eyes of 76 patients of hemodialysis and 32 patients of peritoneal dialysis were studied. Ocular surface staining (OSS) scores were low. Impression cytology showed a drop in goblet cell density, presence of squamous metaplasia, and conjunctival keratinization significantly more in the hemodialysis group. No correlation was seen between the presence of conjunctival calcification and aortic calcification.
Conclusion The hemodialysis group had mild subclinical dry eye but keratinization of conjunctiva was seen. Similarly, advanced squamous metaplasia was seen in the peritoneal dialysis group. These changes were positively correlated to decrease in goblet cell density.

Abstract
Introduction Peripheral neuropathy is one of the most common complications in chronic kidney disease (CKD). The neuroprotective role of ghrelin is being explored recently. Here we aim to determine the burden of neuropathy in nondiabetic CKD and to find the association of peripheral nerve function with plasma ghrelin levels in these patients. Methods This was a cross-sectional study conducted in nondiabetic CKD patients on conservative management to determine the magnitude of neuropathy. The association of ghrelin isoforms with nerve functions was assessed between three groups, namely CKD with neuropathy, CKD without neuropathy, and healthy volunteers, with 20 participants in each group. Results The proportion of neuropathy in nondiabetic CKD was 78% (n = 78), of which 51% (n = 40) were asymptomatic. Des acyl ghrelin (DAG) and total ghrelin (TG) levels were 1545.5 ± 487.4 and 1567.4 ± 485.3 pg/mL, respectively, in CKD patients with neuropathy and were found to be elevated compared to those without neuropathy, who had 1000.4 ± 264.2 and 1019.7 ± 264.3 pg/mL of DAG and TG, respectively (P < 0.001). Assessment of correlation between nerve conduction parameters and DAG levels showed positive correlation between DAG levels and common peroneal latency (r = 0.69; P < 0.01), median sensory latency (r = 0.45; P < 0.05), and sural latency (r = 0.51; P < 0.05). We found negative correlation between median velocity (r =-0.56; P < 0.05), common peroneal velocity (r = -0.64; P < 0.01), median sensory velocity (r =-0.49; P < 0.05), and sural velocity (r = -0.54; P < 0.05). There was no statistically significant difference in acyl ghrelin levels among the groups. Conclusion The prevalence of peripheral neuropathy in CKD is significantly higher with almost half of them being asymptomatic. Impaired renal clearance in CKD leads to the accumulation of DAG, which subsequently inhibits the neuroprotective functions of AG leading to neuropathy in CKD.

Abstract
Human immunodeficiency virus (HIV)-associated renal disease is a pan-nephropathy, causing glomerular, tubular, and interstitial changes. The common lesion is the collapsing variant of focal segmental glomerulosclerosis. Multiple myeloma presenting as light chain cast nephropathy in an HIV-positive patient is very rare. A 45-year-old female retropositive patient presented with one episode of hematuria. Kidney biopsy was performed with a clinical diagnosis of acute interstitial nephritis (AIN). Biopsy showed unremarkable glomeruli. Tubules were dilated and showed a few periodic acid-Schiff (PAS) positive and many PAS-negative fractured casts surrounded by histiocytic reaction. Immunofluorescence and immunohistochemistry (IHC) showed lambda restriction by the casts. Bone marrow aspirate showed an increase in plasma cells, and the biopsy showed nodular aggregates of atypical plasma cells, which showed lambda restriction by IHC. PAS-negative fractured tubular casts are known to be associated with HIV-related nephropathy and need detailed hematological workup to rule out an associated plasma cell dyscrasia.

Abstract
OBJECTIVES To evaluate the etiology of pediatric chronic kidney disease (CKD), assess comorbidities, and identify rate of progression of CKD and its risk factors. METHODS Children aged 2-18 y with the Kidney Disease Improving Global Outcome (KDIGO) CKD stages 2-4 were enrolled. The etiology of CKD and its comorbidities were recorded. Kaplan-Meier survival curves were used to analyze the time to progression of CKD. RESULTS Of the 131 patients enrolled, CKD stages 2, 3a, 3b, and 4 constituted 62 (47.3%), 17 (13%), 26 (19.8%), and 26 (19.8%), respectively. At the last follow-up [at median (IQR) 24 (12, 30) mo], the number of children in CKD stages 2, 3a, 3b, 4 and 5 were 48 (36.6%), 16 (12.2%), 23 (17.6%), 28 (21.4%), and 16 (12.2%), respectively. Etiologies of CKD included obstructive uropathy [48 (36.6%)], chronic glomerular disease [19 (14.5%)], reflux nephropathy [14 (10.7%)] and cystic renal disease [11 (8.3%)]. Comorbidities during follow-up included CKD-MBD [87 (66.4%)], metabolic acidosis [95 (72.5%)], hypertension [88 (67.1%)], growth retardation [69 (52.6%)], and anemia [63 (48.1%)]. The number of patients with metabolic acidosis, hypertension, MBD and anemia in CKD stage 2 were 27 (56%), 26 (54.2%), 24 (50%), 15 (30%), respectively. The median (IQR) rate of decline in eGFR was 3.3 (2, 4.6) mL/min/1.73 m2/y. On multivariable analysis, proteinuria [hazard ratio 3.5 (95% CI 1.4, 8.8) p = 0.01] and hyperphosphatemia [hazard ratio 2.2 (95% CI 1.1, 4.3) p = 0.03] were significant predictors for progression of CKD. CONCLUSIONS Even the earlier stages of CKD had significant comorbidities. The median decline in eGFR was 3.3 mL/min/1.73 m2/y. Proteinuria and hyperphosphatemia were the risk factors for progression of CKD.

Abstract
Introduction: Fluid overload in chronic kidney disease (CKD) is an independent risk factor for all-cause mortality. The volume of ultrafiltrate removed during haemodialysis is usually assessed clinically. Assessment of overhydration by body composition monitor (BCM) using bioimpedance spectroscopy is an objective method. This study was conducted to identify the prevalence of overhydration in CKD patients on maintenance haemodialysis and thereby assess the effects of BCM targeted dry weight attainment. Methods: All patients included in the study were assessed for one month before enrolment for blood pressure, intradialytic events during each dialysis and BP medications. Overhydration was defined as the ratio of overhydration to extracellular water (OH/ECW) > 1.1. Overhydrated patients were brought to BCM targeted dry weight by increasing ultrafiltrate to 500mL/week more than their routine intradialytic weight gain. The effect of attaining BCM target dry weight on blood pressure and intradialytic events were analysed. Results: Out of 110 patients, overhydration was seen in 30 (27.2%); only 20 had clinically evident overhydration. Body composition monitor guided dry weight was achieved in 28 of the 30 patients after a mean duration of 20 weeks. After achieving the target dry weight, there was a significant reduction in intradialytic hypertension events (2.37 vs 1.82 events per session, p-value 0.01). Surprisingly, there was a reduction in episodes of intradialytic hypotension as well, though this did not reach statistical significance. There was a clinically significant reduction in mean systolic and diastolic blood pressures (mean of 5.7mmHg and 2.8mmHg, respectively). Conclusion: The study underlines the importance of BCM-based hydration status assessment and target dry weight attainment in better control of intradialytic events and blood pressure in patients on maintenance haemodialysis.

Abstract
Background In renal transplant patients, the biopsy-proven incidence of polyomavirus nephropathy (PVN) is approximately 5%. There is no consensus in the morphologic classification of definitive PVN, which is attempted in the Banff 2019 Working Group classification, which groups histologic changes, reflects clinical presentation, and facilitates comparative outcome analyses. This study aims to analyze the clinical and histopathological findings and outcomes among the three classes in the recent classification. Materials and methods The study was conducted in the department of pathology and nephrology over a period of six years. All cases diagnosed as PVN on renal allograft biopsies were included. The clinical and biochemical findings were obtained from hospital records. Histopathology slides were reviewed and classified according to Banff 2019 criteria and were analyzed with clinical, laboratory, histopathological parameters along with the clinical outcome. Results Out of 205 renal transplants performed during the study period, 14 patients (6.8%) were diagnosed with PVN. The mean age of diagnosis was 38 years, with a Male: Female ratio of 1.8:1. The median period of diagnosis of the viral infection after transplant was 10 months. Histomorphology grading according to Banff 2019 revealed four cases (28.5%) in PVN class 1, eight cases (57.2%) in PVN class 2, and two cases (14.3%) in PVN class 3. Cases in PVN class 1 presented early. PVN class 1 was associated with a single type of inclusion, and multiple type inclusions were observed in higher classes. Associated diseases were thrombotic microangiopathy (TMA), borderline cellular rejection, antibody-mediated rejection (ABMR), and concomitant infections. PVN class 1 had a better outcome compared to PVN class 2 and class 3. Conclusion PVN1 was observed to have better clinical presentation and outcomes than PVN2 and 3; however, this could not be statistically concluded due to the low sample size and other associated diseases.

Abstract
Background Chronic kidney disease (CKD) is an important cause of morbidity and mortality worldwide. There is a lack of information on epidemiology and progression of CKD in low–middle income countries. The Indian Chronic Kidney Disease (ICKD) study aims to identify factors that associate with CKD progression, and development of kidney failure and cardiovascular disease (CVD) in Indian patients with CKD. Methods ICKD study is prospective, multicentric cohort study enrolling patients with estimated glomerular filtration rate (eGFR) 15–60 mL/min/1.73 m2, or >60 mL/min/1.73 m2 with proteinuria. Clinical details and biological samples are collected at annual visits. We analysed the baseline characteristics including socio-demographic details, risk factors, disease characteristics and laboratory measurements. In addition, we compared characteristics between urban and rural participants. Results A total of 4056 patients have been enrolled up to 31 March 2020. The mean ± SD age was 50.3 ± 11.8 years, 67.2% were males, two-thirds of patients lived in rural areas and the median eGFR was 40 mL/min/1.73 m2. About 87% were hypertensive, 37% had diabetes, 22% had CVD, 6.7% had past history of acute kidney injury and 23% reported prior use of alternative drugs. Diabetic kidney disease, chronic interstitial nephritis (CIN) and CKD-cause unknown (CKDu) were the leading causes. Rural participants had more occupational exposure and tobacco use but lower educational status and income. CIN and unknown categories were leading causes in rural participants. Conclusions The ICKD study is the only large cohort study of patients with mild-to-moderate CKD in a lower middle income country. Baseline characteristics of study population reveal differences as compared with other cohorts from high-income countries.

Abstract
OBJECTIVE To evaluate the association of maternal serum biomarkers of myocardial damage, oxidative stress and angiogenic imbalance with maternal adverse outcomes in women with severe pre-eclampsia. METHODS This was a prospective cohort study, where maternal serum biomarkers were evaluated in women admitted with severe pre-eclampsia to a tertiary care centre between March 2019 and February 2020. Serum markers included brain naturetic peptide (BNP), cardiac troponin-T (cTnT), cystatin-C (cys-C), soluble fms-like tyrosine kinase-1 (sFlt-1), placental growth factor (PlGF), Total Anti-Oxidant status (TAO) and malondialdehyde (MAO). Main outcome measures were adverse maternal outcomes defined as eclampsia, pulmonary oedema, acute kidney injury, placental abruption and HELLP syndrome. RESULTS Adverse maternal outcomes occurred in 93(37.2%, 95% CI: 31.2%-43.6%) of the 250 women with severe pre-eclampsia included in the study, including 21 with pulmonary oedema, 25 with acute kidney injury and 36 with eclampsia. BNP levels were higher among women who developed pulmonary oedema (55.4 pg/mL vs 42.0 pg/mL, p = 0.008). TAO levels were higher in women who developed eclampsia (4.6 mM, IQR 3.1-5.7, p < 0.001) and acute kidney injury (4.1 mM, IQR 3.2-6.3, p = 0.002) compared to those who did not develop any complications (2.93 mM, IQR 2.3-4.1). CONCLUSIONS Even though the endothelial dysfunction and oxidative stress biomarkers were associated with development of preeclampsia, it may have limited utility in identifying women who might develop adverse outcomes.

Abstract
Background: Although malignant hypertension begets multiple target organ damage, there is limited data on patients with severe renal injury and evident malignant hypertension in renal histopathology. Methods: We assessed the baseline demographic, histopathological findings and clinical outcomes in this retrospective analysis of patients with biopsy-proven malignant hypertension. Results: Thirty cases were analysed, the mean age of patients was 40 ± 11.5 years, 28 (93.3%) were males and the average systolic and diastolic blood pressures at hospitalisation were 197.04 ± 24.14 and 117.41 ± 18.31 mmHg, respectively. Severe retinopathy was seen in 10 (33.3%). The median eGFR at admission was 6.3 (IQR 4.4–9.15) mL/min and 21 (72.4%) needed dialysis. Nine (30%) cases with glomerular crescents were having the primary glomerular disease (7 IgAN, 1 C3 glomerulonephritis, 1 membranoproliferative glomerulonephritis) and 17 (56.6%) had thrombotic microangiopathy. Three-month ESRD free survival was 34.5% (n = 10) and the ESRD cohort had more incidence of dialysis requiring kidney injury at presentation (94.4% vs. 40% in the non-ESRD cohort). Patient survival at 1 year was 50%. Isolated malignant hypertension, differed from others with regard to lesser incidence of severe retinopathy, less glomerular sclerosis (29.61 ± 15.86 vs. 48.45% ± 30.78; P = 0.03), absence of crescents (P = 0.02), more incidence of tuft wrinkling (100% vs. 35%, P = 0.00) and total vessel occlusion (P = 0.02). Conclusion: Clinicopathologically, accelerated essential hypertension differs from hypertension of glomerular disease. Degree of kidney injury at presentation is risk predictor for long-term morbidity in malignant hypertension.

Abstract
Chronic kidney disease (CKD) not associated with known risk factors has been reported from parts of India and is presumed to be similar to CKD of unknown etiology (CKDu) that has been described from Central America. The reports from India have been fragmented without clear description of the disease phenotype or its determinants. This paper summarizes the current state of knowledge around CKDu in India based on a review of literature, multi-stakeholder consultation, and a survey of Indian nephrologists. We also contacted individual research groups to solicit data. Our findings suggest that that CKDu is reported from most regions in India; however, it is interpreted differently from the phenotype described from Central America and Sri Lanka. The differences include lack of a clear demographic or occupation group, older age of affected participants, and presence of mild hypertension and low-grade proteinuria. Well-designed prospective field studies with appropriate diagnostic workup are needed to establish the disease burden and identify etiologies, along with socioeconomic and health consequences, the intersection with the environment, and the public health response. Community-based research should phenotype the entire CKD population rather than be restricted to cases with presumed CKDu based on predefined criteria. Guidelines are needed for clinical evaluation, referral, management, and harmonization of clinical documentation and health records. More data are needed to support the existence of a unique CKDu phenotype in India.

Abstract
Introduction Patients with chronic kidney disease (CKD) require multiple medications. There is no information on prescription patterns or the use of evidence-based therapies for management of CKD from low-middle-income countries. Using baseline data from the Indian CKD (ICKD) cohort, we describe the drug prescription practices in patients with mild to moderate CKD. Methods The ICKD study is a prospective, observational cohort study of mild to moderate kidney disease across 11 centers in India. We analyzed all the prescriptions captured at enrollment in the ICKD study. Drugs were categorized into 11 different groups. We provide descriptive data on prescription details and evaluate the appropriateness of medication use. Results Complete prescription data were available in 3966 out of 4056 (97.8%) subjects enrolled in the ICKD database. Most patients had stage 3 CKD, 24.9% had diabetic kidney disease, 87% had hypertension, and 25.5% had moderate to severe proteinuria. Renin-angiotensin-aldosterone system blockers were prescribed in less than half (47.9%) and in 58.8% of patients with proteinuric CKD. Metformin was prescribed in 25.7% of diabetic subjects with CKD. Only 40.4% of patients were taking statins; 31.1% and 2.8% subjects with anemia were receiving iron and erythropoiesis-stimulating agents, respectively. Conclusion This study highlights the missed opportunities for improving outcomes through appropriate prescriptions of drugs in patients with CKD. There is need for dissemination of evidence-based guidelines and institution of sustainable implementation practices for improving the overall health of patients with CKD.

Abstract
This study was performed to evaluate the efficacy of cholecalciferol in improving renal and vascular functions in vitamin D-deficient patients with type 2 diabetes mellitus (T2DM) along with chronic kidney disease (CKD). One hundred patients (18 - 65 years), having T2DM along with CKD (stage IIIA and IIIB) and hypovitaminosis D were randomized (1:1) to receive either oral cholecalciferol 60,000 IU (Group A) or placebo (Group B) weekly for 8 weeks along with standard background treatment. They were followed up for another 24 weeks. Various parameters of renal and vascular functions were compared. Except for serum calcium and phosphate levels which were significantly higher in Group A (p < 0.001), there was no significant difference in any of the biochemical or vascular parameters between the two groups at 8 weeks. There were comparable changes in urinary albumin-creatinine ratio and carotid-femoral pulse wave velocity in the two groups at 8 and 24 weeks. There was no improvement in any of the vascular parameters from the corresponding baseline values in the two groups at 8 and 32 weeks. No improvement in renal and vascular functions was observed following treatment with oral cholecalciferol in patients with T2DM and CKD.

Abstract
Background There is only limited information on the utility of urinary biomarkers in predicting long-term kidney function following acute kidney injury (AKI). The current study assessed whether urinary beta 2 microglobulin/creatinine (B2M/creat) and kidney injury molecule-1/creatinine (KIM-1/creat) ratios, measured in the early recovery phase of AKI, are predictive of kidney function at one year. Methods This is a prospective study done in a tertiary care centre in South India, from March 2017 to December 2018. Adult patients who survived an episode of AKI were followed up for one year (n=125). B2M/creat and KIM-1/creat ratio were measured at two weeks and three months following AKI. Results In the AKI survivors, the B2M/creat ratio at 2 weeks [18.3mg/g (IQR 2.3, 52.9)] and KIM-1/creat ratio [1.1 µg/g (IQR 0.5, 4.0) at two weeks were higher compared to healthy controls [B2M/creat ratio 0.35 mg/g (0.17,0.58) and KIM-1/creat ratio 0.40 µg/g (0.23,1.00); P=<0.001]. After adjusting for covariates, the eGFR and urinary B2M/creat ratio at two weeks following AKI were predictive of eGFR at one year (P<0.001). KIM-1/ creat ratios were not predictive of eGFR at one year. A urinary B2M/creat ratio of 10.85 at two weeks following AKI had an 85.5% sensitivity (95% CI 74, 93) and 64.3% (95% CI 53, 75) specificity to predict CKD at one year. An eGFR cutoff of 60 mL/min/1.73 m2 at two weeks had a sensitivity of 81.8% (95% CI 69, 90) and specificity of 71.4% (95% CI 60, 81) for predicting CKD. The presence of either one criteria (urinary B2M/creat ratio >10.85 (mg/g) or eGFR <60 mL at two weeks) had a sensitivity of 100% (95% CI 94%, 100%) in predicting CKD at one year. Conclusion An eGFR <60 mL/min/1.73m2 and elevated urinary B2M/creat ratio at two weeks following AKI is predictive of low eGFR at one year. Urinary KIM-1/creat ratios do not predict CKD progression.

Abstract
Introduction: Upper gastrointestinal symptoms such as nausea, vomiting, abdominal bloating, and poor appetite are more frequent among chronic kidney disease (CKD) patients and may contribute to poor nutritional intake and malnutrition. Delayed gastric emptying (GE), one of the important contributors to these symptoms, has not been evaluated systematically in different stages of non-diabetic CKD, among Indian patients. Materials and Methods: This hospital-based, cross-sectional analytical study aimed to find out the frequency of delayed GE in non-diabetic CKD (stages: 3,4,5) patients and also to study the correlation between delayed GE and symptoms of gastroparesis, autonomic neuropathy and nutritional parameters. Patients were subjected to evaluation of symptoms of gastroparesis by standardized questionnaire (gastroparesis cardinal symptom index), nutritional status (by anthropometric measures and serum albumin), autonomic function by heart rate variability (HRV) and GE by gastric scintigraphy with a standardized solid rice idli (savory cake) meal labeled with technetium-99m sulfur colloid. Results: Of the 89 non-diabetic CKD (stages-3,4,5) patients evaluated, 22 (≈25%) had delayed GE and 8 (≈9%) rapid GE. Prevalence of delayed GE was higher among stage 5 (15/49, 31%) compared to stages 3 and 4 (7/40, 17.5%), though the difference was statistically insignificant. There was no association between delayed GE and symptoms of gastroparesis and autonomic neuropathy. Though not statistically significant, nutritional parameters (body mass index, skinfold thickness, and serum albumin) were poorer in the delayed GE group compared to the rest. Conclusion: Delayed GE, irrespective of symptoms, may contribute to malnutrition and hence should be looked for in non-diabetic CKD patients with unexplained malnutrition.

Abstract
Snake bite is an important cause for acute kidney injury (AKI) in the tropics and the victims are often otherwise healthy young adults without conventional risk factors for chronic kidney disease (CKD). Available literature on long-term outcomes of AKI -snake envenomation is limited, with only two small retrospective studies with follow-up periods of two years or less. In a hospital-based prospective and retrospective follow-up study, all consecutive adult patients who developed AKI and discharged alive were recruited in the prospective group and for retrospective analysis, we retrieved medical records of patients hospitalized with snake bite from the digitized medical records. Clinical and biochemical characteristics during hospitalization and on follow-up were collected. We recruited 193 patients with snake bite and AKI in a prospective (140) and a retrospective (53) group. Of the 193 AKI patients, 162 (84%) had estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 at the time of discharge from hospital and at follow-up (n = 171) 29 (16.9%) had eGFR<60 mL/min/1.73 m2. Of the 116 patients with follow-up beyond one year, 30 (26%) had CKD. Overall 26 to 28% of patients went on to develop CKD depending on the duration of follow-up. Only very few (1.16%) patients progressed to ESRD. This is the largest follow-up study so far on snake bite-related AKI and provides further evidence that snake bite-associated AKI causes CKD on long-term follow-up. Older age, diabetes, severe AKI, and inadequate anti-snake venom administration were risk factors for the development of CKD on follow-up.

Abstract
Introduction Chronic kidney disease (CKD) is being increasingly recognized as a public health problem in India. The entity of CKD of undetermined etiology (CKDu) is increasingly being reported globally. Here we describe the burden of CKDu in a heretofore undescribed population in South India. Methods We prospectively enrolled all patients with CKD referred to the nephrology department in an observational registry. We analyzed their sociodemographic and clinical features over 4 years. The diagnosis of CKD and its etiology was determined using predefined criteria. Geolocalization of CKD patients was performed. Subsequently, CKD screening was conducted in a village located in an area of CKDu clustering. Results A total of 2424 patients were analyzed; the median age was 52 years and 75.3% were male. Seventy-five percent had advanced CKD. CKDu was the most common (51.7%) etiologic category. This is the highest proportion of CKDu reported among all published CKD studies to date from India. The clinical and demographic profile of this patient population match that of CKDu patients reported from Sri Lanka and Central America, where CKDu is endemic. A clustering of cases of CKDu was noted in specific districts using a geographic information system software. Screening of 447 people in an outreach program at a village located in an area identified to have clustering of CKDu showed a CKD prevalence of 19%. Conclusion We report a previously unrecognized endemic area of CKDu among the underprivileged population engaged in agricultural labor in coastal southeastern India in the states of Tamil Nadu and Puducherry (Tondaimandalam) in India.

Abstract
BACKGROUND Metabolic acidosis (MA) is associated with a loss of muscle mass and faster deterioration of kidney function in patients with chronic kidney disease (CKD). A few single-centre randomized trials have reported favourable outcomes following correction of MA. Additional good quality evidence on the safety and efficacy of alkali supplementation is required in epidemiologically different patient subsets with CKD. METHODS A single-centre, open-label, randomized, prospective parallel-group study was conducted to assess the effect of correction of MA on body composition and kidney function. A total of 188 patients with CKD stages 3 and 4, with venous bicarbonate levels <22 mEq/L were randomized. The intervention arm received standard care as per Kidney Disease: Improving Global Outcomes (KDIGO) 2012 guidelines along with oral sodium bicarbonate supplementation to maintain venous bicarbonate levels at 24-26 mEq/L, whereas the control group received standard care alone. The mid-arm muscle circumference (MAMC), lean body mass (LBM) and estimated glomerular filtration rate (eGFR) were compared between the groups at the end of 6 months. RESULTS The intervention arm showed a higher LBM {36.8 kg [95% confidence interval (CI) 36.5-37.1] versus 36 [35.7-36.4]; P = 0.002} and MAMC [22.9 cm (95% CI 22.8-23) versus 22.6 (22.5-22.7); P = 0.001] when compared with the control group. The GFR in the intervention arm was higher [32.74 mL/1.73 m2 (95% CI 31.5-33.9) versus 28.2 (27-29.4); P ≤ 0.001]. A rapid decline in GFR was documented in 39 (41.5%) patients in the control arm and 19 (20.2%) patients in the intervention arm (P = 0.001). CONCLUSIONS Alkali supplementation to increase venous bicarbonate levels to 24-26 mEq/L is associated with preservation of LBM and kidney function in patients with CKD stages 3 and 4.

Abstract
INTRODUCTION The ORNATE India project is funded by the UK Research and Innovation (UKRI) through the Global Challenges Research Fund. The aim is to build research capacity and capability in India and the UK to tackle global burden of diabetes-related visual impairment. As there are over 77 million people with diabetes in India, it is challenging to screen every person with diabetes annually for sight-threatening diabetic retinopathy (DR). Therefore, alternate safe approaches need to be developed so that those at-risk of visual impairment due to DR is identified promptly and treated. METHODS The project team utilised diverse global health strategies and research methods to co-design work packages to build research capacity and capability to ensure effective, affordable and efficient DR services are made available for the population. The strategies and methods employed included health system strengthening; implementation science; establishing care pathways; co-designing collaborative studies on affordable technologies, developing quality standards and guidelines to decrease variations in care; economic analysis; risk modelling and stratification. Five integrated work packages have been developed to deal with all aspects of DR care. These included implementation of a DR screening programme in the public health system in a district in Kerala, evaluating regional prevalence of diabetes and DR and assessing ideal tests for holistic screening for diabetes and its complications in 20 areas in India, utilising artificial intelligence on retinal images to facilitate DR screening, exploring biomarker and biosensor research to detect people at risk of diabetes complications, estimating cost of blindness in India and risk modelling to develop risk-based screening models for diabetes and its complications. A large collaborative network will be formed to propagate research, promote shared learning and bilateral exchanges between high- and middle-income countries to tackle diabetes-related blindness.

Abstract
BACKGROUND AND OBJECTIVES Patient-reported outcomes have gained prominence in the management of chronic noncommunicable diseases. Measurement of health-related quality of life is being increasingly incorporated into medical decision making and health care delivery processes. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The Indian Chronic Kidney Disease Study is a prospective cohort of participants with mild to moderate CKD. Baseline health-related quality of life scores, determined by the standardized Kidney Disease Quality of Life 36 item instrument, are presented for the inception cohort (n=2919). Scores are presented on five subscales: mental component summary, physical component summary, burden, effect of kidney disease, and symptom and problems; each is scored 0-100. The associations of socioeconomic and clinical parameters with the five subscale scores and lower quality of life (defined as subscale score <1 SD of the sample mean) were examined. The main socioeconomic factors studied were sex, education, occupation, and income. The key medical factors studied were age, eGFR, diabetes, hypertension, and albuminuria. RESULTS The mean (SD) subscale scores were physical component summary score, 43±9; mental component summary score, 48±10; burden, 61±33; effects, 87±13; and symptoms, 90±20. Among the socioeconomic variables, women, lower education, and lower income were negatively associated with reduced scores across all subscales. For instance, the respective β-coefficients (SD) for association with the physical component summary subscale were -2.6 (-3.4 to -1.8), -1.5 (-2.2 to -0.7), and -1.6 (-2.7 to -0.5). Medical factors had inconsistent or no association with subscale scores. The quality of life scores also displayed regional variations. CONCLUSIONS In this first of its kind analysis from India, predominantly socioeconomic factors were associated with quality of life scores in patients with CKD.

Abstract
OBJECTIVES Skinfold thickness measurements for assessing body composition are reported to have good reproducibility compared to the reference method of dual energy absorptiometry (DXA). In the current study, we compared the level of agreement between body composition measured with DXA and skinfold thickness (SFT) in CKD Stage 3 and 4, at 2 occasions, 6 months apart. METHODS Body composition was assessed in 177 Indian patients with CKD Stage 3 and 4 using DXA and anthropometry (SFT). The body fat mass obtained by the 2 methods was compared by paired t-test, intraclass correlation coefficients, regression analysis, and Bland-Altman plots. A linear regression analysis was done to identify the patient-related parameters which would account for the intermethod differences between DXA and SFT. RESULTS Compared to DXA, SFT underestimated the fat mass at baseline as well as 6 months [DXA vs. SFT at entry: 15.85 kg (95% confidence interval, CI 15.07-16.65) vs. 13.71 kg (95% CI 13.21-14.32), P < .001; at 6 months: 16.13 (95% CI 15.33-16.93) vs. 13.85 (95% CI 13.25-14.45), P < .001]. The intraclass correlation coefficients at entry and 6 months were 0.894 (0.857-0.921) and 0.896 (0.860-0.923), respectively. The intermethod differences between DXA and SFT at baseline and 6 months were comparable: 2.08 kg (95% CI 1.66-2.5) at baseline versus 2.27 kg (95% CI 1.83-2.71) at 6 months, P = 0.200. Gender and body mass index turned out to be the significant predictors of intermethod differences at base line and exit (P < .001). CONCLUSIONS SFT-based measurements show good reproducibility compared to DXA over a period of 6 months. However, SFT systematically underestimates the fat mass by 2 Kg compared to DXA.

Abstract
BACKGROUND Organ donation is considered to be a noble act. Medical and nursing students will be the major healthcare providers in this field in the future. Hence, their knowledge, attitude, and perception toward organ donation are essential to improve this field in the future. OBJECTIVE The objective of this study is to assess the knowledge, attitude, and perception on organ donation among undergraduate medical and nursing students. This study brings forth the basic understanding level of the medical and nursing students on the concept of organ donation. METHODS A cross-sectional descriptive study was conducted among the first 4 academic years of medical and nursing students in a tertiary care teaching hospital using convenient sampling. A total of 620 students participated in this study. They were assessed using a pretested semi-structured self-administered questionnaire. The data were analyzed using Statistical Package of the Social Sciences version 19. RESULTS The median score on knowledge, attitude, and perception among the medical students was 16 (14-17), 25 (23-28), and 41 (38-45), respectively, and among the nurses, the scores were 14 (12-16), 25 (22-27), and 39 (33-42), respectively. Almost half (46.9%) of the study participants knew the definition for brain death. Twenty-nine percent of the study participants knew about the existence of law toward organ donation; more than half of those participants (52.7%) mentioned few rules and regulation involved in the laws pertaining to organ donation. CONCLUSION Media is the major source for information. Only less than half of the study participants were knowledgeable on the definition of brain death and existence of organ donation law. Although they are in favor of organ donation, doubts still exist among few of the participants which could be understood through further research in this field.

Abstract
Background Rising rates of resistance to antimicrobial drugs among Enterobacteriaceae limit the choice of therapeutic agents to treat urinary tract infections. In this context we assessed the in-vitro effect of fosfomycin against extended-spectrum beta-lactamases, AmpC beta-lactamases and carbapenemase-producing strains of Escherichia coli, Klebsiella pneumoniae, Enterobacter spp, and Pseudomonas aeruginosa isolated from the patients with urinary tract infection (UTI) and also studied the effect of fosfomycin on their biofilm formation. Materials and methods A total of 326 multidrug-resistant (MDR) isolates comprising of Escherichia coli, Klebsiella pneumoniae, Enterobacter spp, and Pseudomonas aeruginosa from the urine samples of the patients with a diagnosis of UTI were included in the study. MIC 50 and MIC 90 were detected by agar dilution method and the capacity to form biofilm in the presence of fosfomycin by these MDR isolates was assessed by the tissue culture plate method. Results The MIC50 for meropenem (0.5 µgm/mL) and nitrofurantoin (32 µgm/mL) was within the susceptible range only for E. coli. Fosfomycin was the only antibiotic that inhibited 100% E.coli, 70% Klebsiella spp, and 50% Pseudomonas spp and 40% Enterobacter spp which included the extended-spectrum beta-lactamases producers. It showed a similar effect on carbapenemase producers and AmpC producers. Fosfomycin disrupted biofilm in 67% (n=141) E.coli, 74% (n=50) Klebsiella spp, 88% (n=27) Pseudomonas spp and 36% (n=23) Enterobacter spp at 24 hrs of incubation with a concentration of 2 fold dilution lower than that of the MIC. Conclusion Fosfomycin showed a good inhibitory effect on the biofilms produced by the MDR organisms studied here.

Abstract
Rapidly progressive renal failure in anti-neutrophil cytoplasmic antibody (ANCA)- associated renal disease customarily implies crescentic glomerulonephritis with approximately 50% of the glomeruli will have crescents. The tubulointerstitial inflammation is often proportionate to the glomerular inflammation and may have granulomatous pattern adjacent to the glomeruli or an inflamed vessel. A 77-year-old male with rapidly progressive renal failure was myeloperoxidase-ANCA positive, and renal histopathology revealed thrombotic microangio-pathy, significant interstitial inflammation, interstitial granulomas, and arteritis. Pathology is unique for the paucity of the classical crescents and the myriad of extraglomerular features. His renal function improved and stabilized after induction with cyclophosphamide and maintenance with azathioprine.

Abstract
Background Snakebite is a common occupational hazard in tropical countries. To date, the literature on snakebite-related acute kidney injury (AKI) has been limited by retrospective study designs, lack of uniformity in case definitions of AKI and limited follow-up. This study aims to identify the in-hospital outcomes and long-term changes in kidney function that follow haemotoxic envenomation. Methods All adult patients admitted with AKI following haemotoxic envenomation from January 2016 to June 2017 were recruited and followed up until July 2018. Predictors of in-hospital mortality was assessed. Long-term follow-up data on kidney function were collected from survivors. Results In total, 184 patients with haemotoxic envenomation and AKI were recruited. The mean age of the subjects was 42.2 years [95% confidence interval (CI) 40.3–44.7]. The majority were male (71.2%). The mortality of patients with haemotoxic envenomation was 21.5%. The mortality was considerably higher in patients with Kidney Disease: Improving Global Outcomes (KDIGO) Stage 3 AKI [relative risk (RR) 4.45 (95% CI 1.14–17.42)] and those who met KDIGO urine output criteria [RR 20.45 (95% CI 2.84–147.23)]. A Cox regression model identified mechanical ventilation [odds ratio (OR) 5.59 (95% CI 2.90–10.81)], hypotension [OR 2.48 (95% CI 1.31–4.72)] and capillary leak syndrome [OR 2.02 (95% CI 1.05–3.88)] as independent predictors of mortality. Long-term follow-up data were available for 73 patients. A total of 21 patients (28.7%) developed adverse renal outcomes (glomerular filtration rate <60 mL/min/1.73 m2, urine albumin excretion >30 mg/g and new-onset hypertension or prehypertension). Conclusions AKI resulting from snake envenomation is associated with considerable risk of mortality. The greater the AKI stage the greater the likelihood of mortality. One-third of patients with AKI developed long-term complications like chronic kidney disease, prehypertension and hypertension over the follow-up period.

Abstract
Metabolic acidosis is known to have adverse consequences in patients with chronic kidney disease (CKD) including protein-energy wasting, inflammation, bone disease, and disturbance in endocrine function. Unlike in the management of patients with predialysis CKD, bicarbonate levels were not being routinely monitored in dialysis patients at our center. The KDOQI guidelines recommend serum bicarbonate levels ≥22 mEq/L in patients on dialysis. We measured the predialysis serum bicarbonate levels in 100 adult patients on regular hemodialysis (HD) and 41 adult patients on peritoneal dialysis (PD). We also studied the extent of rise in serum bicarbonate levels from predialysis levels after HD in our patients. Predialysis serum bicarbonate level was <22 mEq/L in 73% of patients on HD and 12% of patients on PD. The serum bicarbonate levels remained <22 mEq/L at the end of HD in 41% of patients on HD. Thirty-nine percent of patients were on a HD schedule of thrice a week, and 93% of PD patients performed three PD exchanges a day. The dialysate bicarbonate level was 34 mEq/L. There was a significant increase in serum bicarbonate levels with HD, but the mean postdialysis bicarbonate level was 23.45 mEq/L. A very high proportion of our patients on HD continued to have uncorrected metabolic acidosis, with metabolic acidosis persisting in the immediate postdialysis period in a significant number of patients. Predialysis serum bicarbonate level needs to be monitored in patients on HD. There is an urgent need to modify HD prescription to ensure better correction of metabolic acidosis in our HD population. Compared to HD, the proportion of patients having persistent metabolic acidosis is significantly lower in PD.
