Objectives: Acute kidney injury (AKI) is a major cause of morbidity and mortality. Whether aminophylline administration can prevent or treat AKI among pediatric patients are not clear. This meta-analysis aimed to assess the efficacy and effectiveness of aminophylline for pediatric AKI.
Methods: We carried out a systematic search of six databases: PubMed, EMBASE/Excerpta Medica, Scopus, Cochrane library, and Google Scholar from January 1995 up till May 2019. Summary measures of risk ratios and standard mean difference were calculated using the random effects model.
Results: We identified seven papers containing data on aminophylline use in children with AKI. Meta-analysis of single-arm studies indicated no statistically significant difference in mean rate of serum creatinine clearance (-0.39 [-0.80-1.58], = 0.52), mean urine output (1.99 [-1.43-5.42]; = 0.25), or mean blood urea nitrogen levels (0.83 [-1.86-3.03], = 0.54) before and after aminophylline administration. However, among double-arm studies, aminophylline administration in the intervention arm significantly reduced the serum creatinine level as compared to control arm (mean diff = -34 [-55.18--12.83]; = 0.002). Mean urine output (-112.68 [-27.43-48.9], = 0.17), incidence of AKI (RR = 1.05 [0.80-1.37], = 0.72), and mortality rates (RR = 0.79 [0.42-1.47], = 0.45) were found to be statistically insignificant.
Conclusions: Aminophylline administration in children with AKI reduces serum creatinine level without significant adverse effects or effect on the incidence of AKI, urine output, or mortality. Further, large-scale well-planned randomized controlled trials are needed to evaluate its use and its potential long-term effects.

Article Synopsis
- Fluid overload in pediatric cardiac surgery can lead to serious health issues, and managing it is challenging, with traditional methods potentially harming kidney function.
- This study evaluated aminophylline's effect on fluid balance, urine output, and kidney function in pediatric patients after cardiac surgery, analyzing data from 72 patients who received the drug between September 2022 and December 2023.
- Results showed that aminophylline significantly reduced fluid balance by 115% and doubled urine output in the 24 hours following administration without negatively impacting kidney function markers, indicating it is a safe option for these patients.
Role of aminophylline in prevention of acute kidney injury in term neonates with severe perinatal asphyxia: a randomized open-label controlled trial.

Article Synopsis
- Acute kidney injury (AKI) is a common complication in neonates who experience severe perinatal asphyxia, and the role of aminophylline in preventing it is debated.
- A study involving 81 severely asphyxiated term neonates evaluated the effectiveness of aminophylline as an adjunct to standard care, showing a lower but not statistically significant incidence of AKI in the aminophylline group compared to the control group.
- While aminophylline treatment seemed to temporarily improve urine output, it did not significantly change renal function or lower AKI rates overall.
Methotrexate-induced leukoencephalopathy presenting as acute-onset limb weakness in a child: a case report.

Article Synopsis
- Methotrexate is a key medication for treating childhood cancers like acute lymphoblastic leukemia but can lead to severe side effects such as neurotoxicity, specifically leukoencephalopathy, which usually presents with gradual neurological symptoms.
- A case involving a 10-year-old boy showed acute neurological symptoms, including limb weakness and involuntary movements, after taking oral methotrexate, a rare occurrence compared to traditional administration routes like injection.
- MRI scans revealed brain abnormalities consistent with methotrexate-induced neurotoxicity, highlighting the need for careful monitoring of neurological effects even with oral use of the drug.
Outcomes in patients who received ECMO and/or volatile anesthetics as rescue therapies for status asthmaticus★.
J Extra Corpor Technol

Article Synopsis
- In Kentucky, a study examined children with status asthmaticus (SA) in the Pediatric Intensive Care Unit (PICU) who received treatments like inhaled volatile anesthetics (IVA) and/or Extracorporeal Membrane Oxygenation (ECMO).
- Out of 1772 children with SA, seven received rescue therapies: one received only IVA, five received both IVA and ECMO, and one received only ECMO; all had undergone standard asthma treatments before escalation.
- The findings suggest that while there wasn't a clear benefit of using IVA before ECMO, many patients transitioned to ECMO, hinting that earlier ECMO interventions might be more advantageous despite the risks and high costs involved.
Methylxanthine use in infants with hypoxic-ischemic encephalopathy: a retrospective cohort study.

Article Synopsis
- Therapeutic hypothermia is the main treatment for moderate to severe hypoxic-ischemic encephalopathy (HIE), but it still has high mortality and neurodevelopmental impairment rates of about 30%.
- Methylxanthines, like caffeine and aminophylline, could offer neuroprotective benefits during hypoxic-ischemic injuries, yet data on their safety and effectiveness alongside therapeutic hypothermia is scarce.
- A study involving 52 infants suggested that outcomes for those receiving both methylxanthines and hypothermia were similar to those only getting hypothermia, highlighting the need for further clinical trials to evaluate methylxanthines for HIE treatment, focusing on their safety, efficacy, dosing, and timing
