Methods and compositions for the detection and diagnosis of renal disease and periodontal disease
The disclosure provides compositions and methods for the detection of renal disease and periodontal disease in mammals.
1. A method for diagnosis and treatment of renal disease in a subject comprising detecting an amount of cystatin B polypeptides, comparing the amount of the cystatin B polypeptides to a control sample or control standard, wherein the cystatin B polypeptides are selected from the group consisting of SEQ ID NOs:2, 3, 5, 6, 7, 11, and 12, diagnosing the subject with renal disease where elevated levels of cystatin B polypeptides compared to the control sample or control standard are present, and treating the subject for acute kidney injury or chronic kidney renal disease, wherein the treating comprises surgery for obstructive nephron/ureteroliths, chemotherapy for renal neoplasia, dietary management, enteric phosphate binders, administration of antiproteinurics, administration of antihypertensives, fluid therapy, management of acidosis, administration of diuretics, dialysis, correction of electrolyte abnormalities, administration of antiemetics, administration of antacids, or administration of recombinant erythropoietin.
2. The method of claim 1 , wherein the sample is obtained from a non-human animal.
3. The method of claim 1 , wherein the sample is blood, serum, plasma or urine.
4. The method of claim 1 , wherein the cystatin B polypeptides are detected by, a competitive immunoassay, a sandwich immunoassay, an enzyme-linked immunosorbent assay (ELISA), a turbidimetric immunoassay, a particle-enhanced turbidimetric immunoassay, a radioimmunoassay (RIA), or a western blot assay.
5. The method of claim 1 , wherein the cystatin B polypeptides are detected by an immunoassay.
6. The method of claim 1 , wherein the cystatin B polypeptides are SEQ ID NO:2.
7. The method of claim 1 , wherein the cystatin B polypeptides are SEQ ID NO:3.
8. The method of claim 1 , wherein the cystatin B polypeptides are SEQ ID NO:5.
9. The method of claim 1 , wherein the cystatin B polypeptides are SEQ ID NO:6.
10. The method of claim 1 , wherein the cystatin B polypeptides are SEQ ID NO:7.
11. The method of claim 1 , wherein the cystatin B polypeptides are SEQ ID NO:11.
12. The method of claim 1 , wherein the cystatin B polypeptides are SEQ ID NO:12.
