Steen et al listed criteria for renal crisis associated with scleroderma. A scleroderma renal crisis may be hypertensive or normotensive. The authors are from Georgetown University, the University of Texas Health Science Center in Houston and Boston University.
Parameters:
(1) rise in blood pressure (new onset hypertension)
(2) rise in serum creatinine
(3) proteinuria
(4) hematuria
(5) thrombocytopenia
(6) hemolysis
(7) changes on renal biopsy
Criteria for new onset hypertension - one or more of the following:
(1) systolic blood pressure >= 140 mm Hg
(2) diastolic blood pressure >= 90 mm Hg
(3) rise in systolic blood pressure >= 30 mm Hg
(4) rise in diastolic blood pressure >= 20 mm Hg
Criteria for a rise in serum creatinine - one of the following:
(1) increase > 50% over baseline
(2) serum creatinine >= 1.2 * (upper limit of reference range)
Additional Findings |
Criteria |
proteinuria |
>= 2+ on dipstick |
hematuria |
>= 2+ on dipstick OR >= 10 RBC per high power field (hpf) in urine sediment |
thrombocytopenia |
< 100,000 per µL |
hemolysis |
anemia not due to other cause with either (a) schistocytes or red cell fragments in blood smear OR (b) increased reticulocyte count |
renal biopsy |
microangiopathy consistent with scleroderma renal crisis |
Criteria for hypertensive scleroderma renal crisis - both of the following:
(1) presence of new onset hypertension
(2) one or more of the following:
(2a) rise in serum creatinine
(2b) proteinuria
(2c) hematuria
(2d) thrombocytopenia
(2e) hemolysis
Criteria for normotensive scleroderma renal crisis - all 3 of the following:
(1) absence of new onset hypertension
(2) rise in serum creatinine
(3) one or more of the following:
(3a) proteinuria
(3b) hematuria
(3c) thrombocytopenia
(3d) hemolysis
(3e) renal biopsy findings
