Advances in modern medicine and critical care interventions have greatly impacted survival of critically ill patients, but these interventions are not without consequences. Although patients may now survive the initial critical illness, these patients may not recover to their pre-illness baseline state of health. Recent data in both the critically ill adult and neonatal patients who survive sepsis or surgical events have been shown to progress to persistent inflammatory, immunosuppressed, catabolic syndrome (PICS). This was first identified in adult trauma patients, and more recently was defined in critically ill neonates. To date, there are no published reports of PICS in the critically ill pediatric population. Our long-term goal is to understand PICS in the pediatric population and how early medical and nutritional interventions may impact overall morbidity and survival. To achieve this goal first PICS must first be characterized in the pediatric population. The hypothesis is that PICS occurs in pediatric patients and is associated with increased time to return to a baseline functional life post-injury or illness. The hypothesis will be tested by pursuing the following specific aims. Specific Aim 1: To determine the incidence of PICS in the pediatric population and associate the diagnosis of PICS to survival and time to return to baseline functional life and Specific Aim 2: To determine if early increased inflammatory and immunosuppressive markers are associated with the development of PICS and increased morbidity and mortality. These aims will be accomplished by conducting a prospective single-center observational pilot study to enroll pediatric patients with an anticipated pediatric intensive care unit (PICU) stay greater than 14 days. Through these two aims, the investigators anticipate that this research will provide an explanation into the interplay of inflammation, immunosuppression, and catabolism in critically ill children, which is imperative to the development of early therapeutic and nutritional interventions that can reduce morbidity and mortality associated with critical illness.

Other: PICS in critically ill pediatric population
Occurrence of PICS in the pediatric critical care population [ Time Frame: July 1, 2018 to June 30, 2019 ]
Diagnosis of PICS will be determined when a patient has been admitted to the PICU for >14 days and has signs of both inflammation (CRP >15mg/L) and immunosuppression (total lymphocyte count < 0.80×109/L), as well as catabolism (Serum albumin < 3.0g/dL, Prealbumin <10mg/dL, Retinol binding protein <10μg/dL, and weight loss >10% or body mass index <18 during hospitalization).
Secondary Outcome Measures :
Mortality [ Time Frame: July 1, 2018 to June 30 2019 ]
Death in the ICU associated with PICS
Biospecimen Retention: Samples With DNA
In addition to CRP and TLC, which will be collected at 14 days (± 1 day) of PICU admission , an additional blood samples will be collected at these time points to be frozen for further analysis. At the time of blood collection, an additional 5 mL of blood will be collected, processed, and stored at -80 degree Celsius. Once desired time-points are identified and further funding obtained, samples will be processed in batches to evaluate biochemical markers of inflammation. This will be performed using The Inflammatory Cytokine Human Magnetic 5-Plex Panel for the Luminex™ platform. This will quantify GM-CSF, IL-1β, IL-6, IL-8 and TNF-α in serum samples.
