NCT03277547

Brief Summary

This is a prospective clinical cohort study that involves a baseline study visit followed by up to 3 annual follow-up study visits for a total follow-up of 36-48 months to evaluate the age- and sex-adjusted rate of change in kidney function, and to identify biomarkers of endothelial function, metabolomic profiles and clinical characteristics for the worsening of kidney function and for a rapid decline in kidney function.

Outcome Measures

Primary Outcomes (4)

  • Age- and sex-adjusted rate of change, over 36 - 48 months, in estimated glomerular filtration rate in patients with sickle cell anemia

    Estimated glomerular filtration rate will be ascertained using the CKD EPI equation

    36-48 months

  • Age- and sex-adjusted rate of change, over 36 - 48 months, in albuminuria in patients with sickle cell anemia

    Evaluate the rate of change in albuminuria by spot urine measurements of albumin-creatinine ratio during designated study visits

    36-48 months

  • Cross-sectional association of biomarkers of endothelial function with kidney function (estimated glomerular filtration rate and albuminuria) in patients with sickle cell anemia

    Plasma levels of ET-1, VEGF and soluble VCAM-1 from samples obtained at designated study visits will serve as measures of endothelial function

    36-48 months

  • Cross-sectional association of urine and plasma metabolomics profiles with kidney function (estimated glomerular filtration rates and albuminuria) in patients with sickle cell anemia

    Untargeted metabolic profiling of plasma and urine will be performed using high-resonance nuclear magnetic resonance spectrometry. Plasma and urine analytes which are significantly associated with estimated glomerular filtration rate and albumin-creatinine ratio will be ascertained.

    36-48 months

Study Population

Patients with HbSS or HbSB0 thalassemia between the ages of 18 and 65 years who meet the eligibility criteria and provide consent to participate in the study

You may qualify if:

  • age of 18 to 65 years;
  • confirmed diagnosis of sickle cell anemia (HbSS and SB0 thalassemia);
  • non-crisis, "steady state" with no severe pain episodes requiring medical contact during the preceding 4 weeks;
  • ability to understand the requirements of the study and be willing to give informed consent.

You may not qualify if:

  • bone marrow transplantation;
  • history of long-standing diabetes mellitus with suspicion for diabetic nephropathy as determined by a nephrologist;
  • known diagnosis of hepatitis B or C infection (patients will not be screened specifically for this during the study);
  • known HIV positive (patients will not be screened specifically for this);
  • history of cancer, except non-melanoma skin cancer;
  • pregnant or breastfeeding;
  • connective tissue disease such as SLE;
  • known glomerular disease unrelated to SCD;
  • patients with ESRD on chronic dialysis.
