Abstract: Renal transplantation is the optimal treatment for children with ESRD. We undertook this study to establish the outcome of pediatric renal transplants in a resource-constrained environment in a developing country. A retrospective analysis on 90 pediatric renal transplants (age at transplant 2 rejection episodes (p = 0.05), while sepsis (p = 0.01) was the most important contributor to patient loss. Pediatric renal transplantation in India can be accomplished successfully. The graft and patient survival in our study, the largest from India, is comparable to those published from developed countries and is encouraging given the limited resources.

Abstract: Studies examining associations between dietary patterns and Framingham risk score (FRS) and predicted 10-year cardiovascular diseases (CVD) risk in an Asian population are lacking. This study aimed to identify a posteriori dietary patterns across three major ethnic groups in Singapore and ascertain their associations with locally modified FRS and predicted 10-year CVD risk. This cross-sectional study included 8594 Singapore residents (aged 21-75 years) from the Singapore Multi-Ethnic Cohort. Data on sociodemographic and lifestyle factors were collected via questionnaires. Food consumption was assessed using a validated Food Frequency Questionnaire. Dietary patterns were identified using principal component analysis and associations with CVD risk factors, FRS and predicted CVD risk (%) were analysed using multiple linear and logistic regression. Four dietary patterns emerged that explained 25.6% of variance. The 'processed food and sugar-sweetened beverages' pattern was significantly associated with higher FRS (β: 0.13 95% CI: 0.04, 0.23), while the 'ethnic breads, legumes and nuts' (β: 0.13 95% CI: 0.22, -0.04) and 'whole grains, fruit and dairy' (β: 0.17 95% CI: 0.24, -0.10) patterns were significantly associated with lower FRS. The 'meat and vegetables' pattern was not significantly associated with FRS. Increased adherence to the 'whole grains, fruit and dairy' pattern was associated with lower odds of having predicted CVD risk of ≥10% (p-trend: 0.03). Adherence to the 'ethnic breads, legumes and nuts' and 'whole grains, fruit and dairy' patterns was associated with a lower predicted CVD risk, and an inverse association for the 'processed food and sugar-sweetened beverages' pattern in an Asian population. These findings can inform the development of culturally sensitive dietary interventions to prevent CVD.

Abstract: Urinary tract infection is the most common form of bacterial infection encountered in a renal transplant recipient. Studies explaining the long-term consequences of acute graft pyelonephritis (AGPN) are few. A total of 1022 consecutive renal allograft recipients were studied retrospectively over a period of 10 years for evidence of AGPN. These patients were classified into two groups according to the presence or absence of at least one AGPN episode. Only culture-proven infections were included in the study. Of the 1022 renal transplant recipients, 169 patients (16.5%) developed AGPN. In the multivariate analysis with stepwise logistic regression, significant associations were observed between AGPN and placement of ureteric stent (odds ratio [OR]=4.6), urological malformations of native kidney (OR=2.1), cytomegalovirus (CMV) disease (OR=2.0), mycophenolate mofetil (MMF)-based regimen (OR=1.9), and acute rejection episodes (OR=1.5). However, age>40 years, female gender, induction therapy, anti-CD3 treatment, and hyperglycemia did not show such an association. In comparison with the non-AGPN group, these patients had a lower graft and patient survival (though it did not attain statistical significance). In the multivariate analysis using the Cox model for the entire study population, AGPN did not independently contribute to poor graft or patient survival. AGPN in the renal transplant setting is an ominous event, as these patients are also more prone to develop bacteremia, acute rejection, and CMV disease, which could then lead to poor graft and patient survival. Its association with MMF needs further clarification.

Abstract: IgA nephropathy (IgAN) is not well characterized in India. This retrospective study of 478 patients with IgAN was performed to clarify the presenting features, prognostic factors and the renal survival rates of the disease. Three hundred and forty-seven patients who had been followed on average for 27 months after diagnosis were ided into two groups based on renal function at diagnosis. In group 1 (229 patients), the creatinine clearance estimated by the Modification of Diet in Renal Disease formula was /=85 mL/min. The predominant modes of presentation were nephrotic syndrome, hypertension and renal failure. Twenty-nine percent of patients had more than a 20% decline in renal function at the last follow up. Multivariate analyses with stepwise logistic regression identified hypertension (odds ratio (OR) 3.5), nephrotic range proteinuria (OR 3.4) and sclerosed glomeruli on biopsy (OR 4.1) to be independently associated with progression in group 1 and hypertension (OR 2.3) in group 2. Seventeen percent of patients progressed to end-stage renal disease (ESRD). Using multivariate analysis by the Cox model, four risk factors for developing ESRD were identified: hypertension (hazard ratio (HR) 3.1) nephrotic proteinuria (HR 1.9) interstitial fibrosis (HR 2.5) and sclerosed glomeruli (HR 1.8). The renal survival rates at 1, 5 and 10 years were 84, 55 and 33%, respectively, with a median renal survival of 61 months from the time of biopsy. The relatively rapid rate of progression of IgAN in India is suggestive towards a 'malignant' nature of the disease in this country.
