Background: The neonate is more susceptible to acute kidney injury (AKI) than others due to functional and developmental immaturity, hemodynamic changes that occur at birth, and possibility of hypovolemia due to increased insensible water losses. The aim of this work was early detection of the occurrence of AKI through measurement of serum cystatin C (CysC) and assessment of renal function in patients with bronchopulmonary dysplasia (BPD) in order to initiate early and appropriate therapeutic measures as indicated. Methods: This prospective observational study was carried out on 50 neonates diagnosed as cases of BPD with gestational age ranging from 28w to 38w. Urea, creatinine and serum CysC were measured twice, the first measurement was at the time of diagnosis of BPD and the second one was 3 days later with estimation of creatinine based Glomerular filtration rate (GFR) and cystatin based GFR.renal Doppler ultrasound was performed to measure peak systolivc velocity, end diastolic velocity and resistive index. Results: There were 7 cases with abnormal GFR According to the first creatinine based GFR. There were 16 cases with abnormal GFR according to the first cystatin C based GFR with no statistically significance difference between both measurements. 5 patients were classified to have AKI based on serum creatinine level. There was statistically significant increase in 1st, 2nd serum creatinine, 1st and 2nd serum cystatin C levels in the AKI patients in comparison to non AKI group. On the other hand, there was statistically significant decrease in 1st, 2nd creatinine based GFR, 1st and 2nd cystatin C based GFR. There was statistically significant increase in mortality in the AKI patients if compared to non AKI patient. There was statistically significant increase in SBP, DPB and PCO2 in the AKI patients in comparison to non AKI group. Conclusions: Measurement of serum CysC and estimation of cystatin based GFR can help in early detection of cases with renal malfunction among the patients with BPD before rise of serum creatinine Early diagnosis will lead to improvement of the outcome and shortening of the hospital stay.

Background: A good survival rate among patients with beta thalassemia major (beta-TM) has led to the appearance of an unrecognized renal disease. Therefore, we aimed to assess the role of serum cystatin-C as a promising marker for the detection of renal glomerular dysfunction and N-acetyl beta-D-glucosaminidase (NAG) and kidney injury molecule 1 (KIM-1) as potential markers for the detection of renal tubular injury in beta-TM children. Methods: This case-control study was implemented on 100 beta-TM children receiving regular blood transfusions and undergoing iron chelation therapy and 100 healthy children as a control group. Detailed histories of complete physical and clinical examinations were recorded. All subjected children underwent blood and urinary investigations. Results: There was a significant increase in serum cystatin-C (p < 0.001) and a significant decrease in eGFR in patients with beta-TM compared with controls (p = 0.01). There was a significant increase in urinary NAG, KIM-1, UNAG/Cr, and UKIM-1/Cr (p < 0.001) among thalassemic children, with a significant positive correlation between serum cystatin-C, NAG and KIM-1 as regards serum ferritin, creatinine, and urea among thalassemic patients. A negative correlation between serum cystatin-C and urinary markers with eGFR was noted. Conclusion: Serum cystatin-C is a good marker for detection of glomerular dysfunction. NAG and KIM-1 may have a predictive role in the detection of kidney injury in beta-TM children.

Objectives: Serum creatinine levels are often used to diagnose acute kidney injury (AKI), but may not necessarily accurately reflect changes in glomerular filtration rate (GFR). This study aimed to compare the prevalence of AKI in children with severe malaria using diagnostic criteria based on creatinine values in contrast to cystatin C. Methods: This prospective cross-sectional study was performed between June 2016 and May 2017 at the University of Ilorin Teaching Hospital, Ilorin, Nigeria. A total of 170 children aged 0.5–14 years old with severe malaria were included. Serum cystatin C levels were determined using a particle-enhanced immunoturbidmetric assay method, while creatinine levels were measured using the Jaffe reaction. Renal function assessed using cystatin C-derived estimated GFR (eGFR) was compared to that measured using three sets of criteria based on creatinine values including the Kidney Disease: Improved Global Outcomes (KDIGO) and World Health Organization (WHO) criteria as well as an absolute creatinine cut-off value of >1.5 mg/dL. Results: Mean serum cystatin C and creatinine levels were 1.77 ± 1.37 mg/L and 1.23 ± 1.80 mg/dL, respectively (P = 0.002). According to the KDIGO, WHO and absolute creatinine criteria, the frequency of AKI was 32.4%, 7.6% and 16.5%, respectively. In contrast, the incidence of AKI based on cystatin C-derived eGFR was 51.8%. Overall, the rate of detection of AKI was significantly higher using cystatin C compared to the KDIGO, WHO and absolute creatinine criteria (P = 0.003, <0.001 and <0.001, respectively). Conclusion: Diagnostic criteria for AKI based on creatinine values may not indicate the actual burden of disease in children with severe malaria.
