Overview
• To Evaluate the role of uromodulin level in early diagnosis of cast nephropathy and to detect its prognostic value in multiple myeloma patients
Detailed description
Multiple myeloma (MM) is a malignant plasma cell disorder . It is the second most common hematologic malignancy worldwide . It accounts for 15%-20% of all hematologic malignancies and has a 5-year survival rate of 60% .
About 31% of newly diagnosed MM patients presented with renal impairment and about 6% to 13% need dialysis , which significantly increases morbidity and mortality, and limits treatment strategies . Most common renal disease in MM is myeloma cast nephropathy that derived from secreted free light chains that combined with uromodulin to form cast which obstructs the distal tubules and presented with severe acute kidney injury . Renal biopsy is the only method to accurately diagnose myeloma cast nephropathy.
Uromodulin, also known as Tamm-Horsfall protein, is a kidney specific glycoprotein which is produced only by the epithelial cells lining the thick ascending limb (85%-90%) and early distal convoluted tubule (10%-15%), and is released to urine and blood . About 200 mg/day of uromodulin is normally excreted in urine . Recently, uromodulin being involved in many pathological processes as hypertension, urinary tract infections, nephrolithiasis, chronic and acute kidney disease.
Limited is known about role of uromodulin in management of myeloma. Measurement of serum uromodulin in patients that newly diagnosed multiple myeloma with and without renal impairment and follow up these patients for 1 year may provide a useful non-invasive predictor of cast nephropathy and may has a prognostic value in myeloma.
Interventions
- Diagnostic test - Serum Uromodulin level quantitative test by ELISA technique at day 0, day 21 of 1st cycle and at the end of 2nd cycle of bortezomib based protocol of chemotherapy.
\- Serum Uromodulin level quantitative test by ELISA technique at day 0, day 21 of 1st cycle and at the end of 2nd cycle of bortezomib based protocol of chemotherapy.
Primary outcome measures
- To assess the predictive value of serum uromodulin level in newly diagnosed patients with multiple myeloma with and without renal impairment as non-invasive marker for myeloma cast nephropathy.. [Time frame: 1 year]
Secondary outcome measures (1)
- To detect correlation between serum uromodulin level and risk stratification, staging and prognosis of newly diagnosed patients with multiple myeloma. [Time frame: 1 year]
Eligibility criteria
Inclusion criteria
- Adult patients ≥ 18 years old that newly diagnosed with multiple myeloma according to 2024 updates in diagnosis of multiple myeloma (10) with and without renal impairment at nephrology and haematology unit of internal medicine department.
Exclusion criteria
- any patient have evidence of renal impairment due to any cause other than multiple myeloma as diabetic nephropathy, hypertensive nephropathy or lupus nephritis ... etc.
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
