Incidence of Acute Kidney Injury and Risk Factors in Newborns With Congenital Diaphragmatic Hernia
Study Overview
Status
Detailed Description
There is an overwhelming number of studies showing that complication with acute kidney injury (AKI) in critically ill patients, including children and newborns results in increased morbidity and mortality. The more severe AKI, the higher risk of bad outcome. In the neonatal intensive care unit (NICU), the incidence of AKI is approximately 30 %, even higher in full-term babies (36 %).
Newborns with congenital diaphragmatic hernia (CDH) often present with severe cardio-respiratory dysfunction, often complicated by pulmonary hypertension (PPHN) requiring mechanical ventilation and vasoactive/inotropic drugs, especially during the first week in the intensive care. Some of these patients deteriorates and cannot maintain vital parameters despite conventional treatment and will therefore require extra corporeal membrane oxygenation). During the ICU-stay, the patients are subjected to several risk factors for developing AKI. Among physiological risk factors, PPHN, low oxygenation and blood pressure may result in renal dysfunction. Iatrogenic factors include the need for nephrotoxic drugs, not least antibiotics (Vancomycin, Gentamycin) and antimycotics. In addition, hyperchloremia may contribute to the development of AKI, since impaired renal blood flow is associated with hyperchloremia. The AKI incidence and its risk factors in CDH patients is not well studied.
The objectives of this well characterized retrospective cohort study is to establish AKI incidence in critically ill CDH-patients and investigate possible associations between risk factors and AKI (exposure to nephrotoxic drugs, degree of multiple organ failure, PPHN, vasoactive/inotropic requirement, oxygenation index, fluid overload and hyperchloremia) during PICU stay. The association of the risk factors to different stages of AKI will also be investigated.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Incidence of acute kidney injury in newborn patients with congenital diaphragmatic hernia (CDH) (n=108)
Time Frame: Acute kidney injury evolving during PICU-stay (from birth up to 10 weeks, which is the longest PICU-stay among the patients).)
|
Patients having or not having acute kidney injury will be determined by the score: neonatal Kidney Diseases: Improving Global Outcomes (n-KDIGO), based upon creatinine concentration (mikromoles/L).
A 1.5-fold increase in creatinine concentration increase from first sampling will be classified as acute kidney injury.
|
Acute kidney injury evolving during PICU-stay (from birth up to 10 weeks, which is the longest PICU-stay among the patients).)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pulmonary hypertension
Time Frame: Developing during PICU-stay (from birth up to 10 weeks)
|
A patient is classified as having PPHN on the first echocardiogram if the right ventricular systolic blood pressure is 67% or more of the systemic blood pressure.
Acute kidney injury will be determined using n-KDIGO described in Primary Outcome Measure.
In the statistic analysis, the variables will be dichotomous.
Possible association will be analysed using logistic regression analysis in this cohort of newborn patients with CDH (n=108)
|
Developing during PICU-stay (from birth up to 10 weeks)
|
Use of nephrotoxic drugs
Time Frame: Given during PICU-stay (from birth up to 10 weeks)
|
If given 3 days or more during PICU-stay, Nephrotoxic drugs (Vancomycin, Meropenem, Gentamycin, Amphotericin B, Tazobactam and Fluconazole) will be investigated using logistic regression analysis to elucidate if there is an association with the development of acute kidney injury (defined by n-KDIGO) in this cohort of newborn patients with CDH (n=108)
|
Given during PICU-stay (from birth up to 10 weeks)
|
Duration (days during first week in the PICU) of hyperchloremia
Time Frame: From birth up to one week in the. PICU.
|
Plasma chloride concentration has been obtained from blood gas analysis on a daily basis during the first week in the PICU.
It will be investigated if days with a chloride concentration >110mmol/L is associated with the development of acute kidney injury (defined by n-KDIGO) using logistic regressionin this cohort of newborn patients with CDH (n=108)
|
From birth up to one week in the. PICU.
|
Development of multiple organ failure.
Time Frame: From birth up to one week in the PICU
|
Maximum development of multiple organ failure during the first week in the PICU will be determined defined by the PEdiatric Logistic Organ Dysfunction Score (PELOD-2-score).
Higher values means a worse.
outcome.
A possible association between PELOD-2 score and the development of acute kidney injury will be investigated using logistic regression in this cohort of newborn patients with CDH (n=108)

Mortality during PICU-stay (max 10 weeks).
Time Frame: PICU-stay. (up to 10 weeks).

Association between the development of acute kidney injury defined by n-KDIGO and mortality occurring during PICU stay will be investigated using logistic regression in this cohort of newborn patients with CDH (n=108)
