Conditions
Brief summary
Patients with sickle cell disease may be at risk for acute kidney injury (AKI)during sickle cell crisis (pain or acute chest syndrome). This study will evaluate the role of hemolysis during SCD crisis on the development of AKI and the role for monitoring urine biomarkers during an admission for crisis and during well clinic follow-up.
Detailed description
Patients admitted to the hospital for acute chest syndrome or vaso-occlusive pain events may consent to participate in this study. Patients will consent to daily blood and urine collection during their hospitalization and during well clinic visits. Each AM, participants will have blood and urine collected, processed, and strored for future analysis of hemolytic markers and biomarkers of kidney injury. Patients will also have strict urine output recorded. Acute kidney injury (AKI) will be defined by the current KDIGO definition based on either a rise in serum creatinine or decline in urine output. Patient medical course will be reviewed to determine interventions and outcomes of their admission based on the development of AKI.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of Acute Kidney Injury | Hospitalizations through study completion, an average of one year | Evaluate the incidence of KDIGO defined AKI among patients admitted for pain or acute chest syndrome. AKI is defined by KDIGO as an increase in SCr by 50% or ≥0.3mg/dL from baseline, or UOP \<0.5mL/kg/hr for 12 hrs |
| Impact of Acute Kidney Injury during Pain or Acute Chest Syndrome Hospitalizations on the Development of Chronic Kidney Disease as defined by KDIGO. | One year | We will evaluate the impact of AKI on eGFR. To evaluate this impact, we will compare the change in eGFR, as measured by cystatin C, obtained from each patient during their non-acute clinic visit both immediately prior to their AKI events and after AKI events. |
| Impact of free heme and endothelin on development of AKI | two years | We will test the hypothesis that free heme and endothelin are elevated in patients that develop AKI as compared to patients without AKI. |
