About this study

Official title: Early Predictor of Acute Kidney Injury in Newborns With Perinatal Asphyxia

The aim of the study is to investigate the role of serum cystatin C (sCysC) as an early predictor for both diagnosis and short term outcome evaluation of acute kidney injury (AKI) in neonates with perinatal asphyxia admitted to Neonatal Intensive Care Unit (NICU) of Assiut University Children Hospital

Read the detailed description

Acute Kidney Injury is defined as the inability of the kidneys to excrete nitrogenous waste products and maintain fluid and electrolyte homeostasis. It is fairly common in newborn population and is a major contributor factor of neonatal mortality and morbidity.

The most common form of Acute Kidney Injury in neonates is prerenal failure due to renal hypo-perfusion or ischemia. Pre-renal failure may result in intrinsic kidney failure if it is not treated promptly. The kidneys of neonates are particularly susceptible to hypo-perfusion because of the physiologic characteristics of neonatal kidneys, including high renal vascular resistance, high plasma renin activity, low glomerular filtration, decreased intra-cortical perfusion rate and decreased reabsorption of sodium in the proximal tubules in the first days of a neonatal life. Thus, newborn infants are vulnerable to acute tubular necrosis or cortical necrosis.

The cause of Acute Kidney Injury in neonates is of multi-factorial etiology and, usually, there is one or more associated contributing factor. In most studies, perinatal asphyxia and sepsis are the most commonly associated conditions.

Perinatal asphyxia is defined as abnormal neurological incident resulting in neonatal hypoxic ischemic encephalopathy , which occurs usually due to brain hypoxia and ischemic incidents. Perinatal asphyxia can result in multi-organ dysfunction through redirection of cardiac output to maintain cerebral, cardiac, and adrenal perfusion while potentially compromising perfusion to non-vital organs including kidneys, this causing Acute Kidney Injury.

The incidence of Acute Kidney Injury after Perinatal asphyxia in term neonates was shown to be around 30% to 56%. Early detection of Acute Kidney Injury could optimize and improve patient outcomes. therefore, the use of biomarkers to predict renal damage has been of interest. Serum creatinine is the most commonly used clinical measure of renal function; however, it is a poor diagnostic marker and its utility is further questionable in neonates since kidneys undergo maturational changes in postnatal period.

Human Cystatin C is a low molecular weight protein, belonging to the cystatin superfamily of protease inhibitors, which is produced at a constant rate in all nucleated cells. Cystatin C is freely filtered through the glomerular membrane, then completely reabsorbed and degraded by the proximal tubule. Serum Cystatin C is being promoted as a more accurate estimate of neonatal glomerular filtration rate.

Acute Kidney Injury was diagnosed on the basis of changes in the serum creatinine level according to the modified neonatal Acute Kidney Injury of Kidney Disease Improving Global Outcome definition (Table 1). AKI was defined as an increase in the serum creatinine level by ≥ 0.3 mg/dL within 48 hours or ≥ 1.5 times from the baseline within 7 days.

Newborns are unique in that the serum creatinine level immediately after birth often reflects maternal levels. Studies have reported that the mean serum creatinine level in preterm infants rises during the first two days of postnatal life, reaches a plateau for a few days, and then decreases thereafter .Therefore, the baseline serum creatinine level was defined as the lowest previous serum creatinine level after 24 hours of age.

TABLE 1 Acute Kidney Injury of Kidney Disease Improving Global Outcome definition:

Stage serum creatinine Urine Output 0 No change or rise < 0.3 mg/dL. ≥ 0.5 mL/kg/h.

  1. rise ≥ 0.3 mg/dL within 48 h or rise ≥1.5-1.9 × reference level* within 7 days. < 0.5 mL/kg/h for 6 to 12 h.
  2. rise ≥ 2.0-2.9 × reference level * < 0.5 mL/kg/h for ≥ 12 h.
  3. rise ≥ 3 × reference level * or serum creatinine level ≥ 2.5 mg/dL or Receipt of dialysis. < 0.3 mL/kg/h for ≥ 24 h or anuria for ≥ 12 h.
  • Reference level will be defined as the lowest previous serum creatinine.

The goal of Acute Kidney Injury management in newborns is to maintain homeostasis until the renal functions return, and is accomplished by addressing fluid and electrolyte imbalance, nutritional needs, and acidosis.Unfortunately, available data on the long-term outcome of neonatal Acute Kidney Injury patients is limited.

The short-term outcome of therapy for Acute Kidney Injury in newborns is dependent on the underlying etiology of Acute Kidney Injury, the involvement of other organs and the availability of renal replacement therapy. As expected, mortality is more frequent and morbidity is much worse in neonates with multi-organ failure.
