We report a rare and intricate case of nesidioblastosis, marked by hyperinsulinemic hypoglycemia, in a patient with diabetes and chronic kidney disease (CKD). PET-CT imaging and histopathology confirmed the condition, culminating in a comprehensive treatment strategy comprising subtotal pancreatectomy and pharmacotherapy. This case marks the first documented occurrence of nesidioblastosis in a patient with CKD and diabetes. The presence of CKD further complicated the clinical picture, influencing hypoglycemic risk, drug efficacy, insulin clearance, and counter-regulatory mechanisms.

Background: Continuous renal replacement therapy (CRRT) is used in hemodynamically unstable patients with acute kidney injury (AKI). Heparin, the most commonly used anticoagulant, has a significant bleeding risk and is associated with heparin-induced thrombocytopenia. Regional citrate anticoagulation is an alternative anticoagulation strategy in CRRT.

Materials and methods: A randomized controlled trial was conducted in the Intensive Care Unit over one year, from October 2020 to September 2021, in patients with AKI requiring CRRT. Fifty-two patients were randomized into two groups: group 1 received regional citrate anticoagulation, and group 2 received heparin anticoagulation.

Results: The mean age in group 1 was 50.46 years, while it was 49.35 years in group 2. The mean filter lifespan in group 1 was 45.11 hours, while in group 2, it was 26.11 hours and was statistically significant (P < 0.001). The mean effective delivered RRT dose was higher in group 1 (26 ml/kg/hour) compared to group 2 (24.23 ml/kg/hour), which was statistically significant (P < 0.001). Bleeding episodes were higher in group 2 than in group 1 (42.3% vs 11.5%), which was statistically significant (P = 0.027). The RCA group had various electrolyte and metabolic complications, but these were not statistically significant.

Conclusion: Regional citrate anticoagulation is better than heparin anticoagulation in terms of filter lifespan, effective delivered RRT dose, bleeding episodes, and metabolic complications.

Point of care ultrasound (POCUS) is gaining wide recognition in its bedside applications. The day-to-day practice of nephrology requires several ultrasonographic parameters for diagnosis. Hence, familiarity with basics of renal ultrasound imaging is becoming a necessary skill for every nephrologist. This review provides an overview of the normal and abnormal findings in a graft kidney and its environment throughout graft survival and after its failure. The correlative understanding of the clinical features with image findings provides the greatest advantage in applying POCUS at the bedside.

Background: There are two criteria to diagnose and stage acute kidney injury (AKI) in children: pediatric-Risk, Injury, Failure, Loss (p-RIFLE) and Kidney Disease Improving Global Outcomes (KDIGO). This study aims to find out the extent of agreement in diagnosis (by p-RIFLE and KDIGO) and risk factors of AKI in pediatric diabetic ketoacidosis (DKA).

Materials and methods: A retrospective cohort study involving children aged ≤15 years with DKA was conducted between January 2014 and December 2022. Those with inborn errors of metabolism, septic shock, and urinary tract disease were excluded. The primary outcome was the extent of agreement in diagnosis of AKI by p-RIFLE and KDIGO. The secondary outcomes were staging agreement, risk factors, complications (hypoglycemia, hypokalemia, and cerebral edema), time to resolution of DKA, and hospital and pediatric intensive care units (PICU) stay.

Results: Data from 161 patients were collected. Mean (SD) age was 8.6 (3.7) years. Good agreement between p-RIFLE and KDIGO criteria for diagnosis of AKI was noted at admission (Kappa = 0.71, p ≤ 0.001), at 24 hours (Kappa = 0.73, p ≤ 0.001) and discharge (Kappa = 0.60, p ≤ 0.001), and for the staging of AKI at admission (Kappa = 0.81, p ≤ 0.001) at 24 hours (Kappa = 0.75, p ≤ 0.001) and discharge (Kappa = 0.48, p ≤ 0.001). On multivariate analysis, age (≤5 years: aOR = 3.03, 95% CI 1.04-8.79) is an independent risk factor for AKI at discharge by KDIGO. Cerebral edema (n = 6, 3.7%), hypoglycemia (n = 66, 41%), and hypokalemia (n = 59, 36.6%) were noted. Resolution and stay in PICU and hospitals were longer for patients with AKI.

Conclusion: p-RIFLE and KDIGO criteria showed good agreement in diagnosis and staging of AKI in pediatric DKA.
