ABAR is an acronym that stands for "Against BILAG-associated Renal lupus." It is a medical term used in the field of rheumatology to describe a specific type of kidney disease that occurs in individuals with systemic lupus erythematosus (SLE). Lupus nephritis is a common manifestation of SLE, characterized by inflammation and damage to the kidneys.
When referring to ABAR, it implies the presence of specific antibodies called anti-BILAG domain antibodies. These autoantibodies are directed against various proteins in the kidney and are often associated with more severe renal involvement in SLE patients. ABAR-positive lupus nephritis cases tend to have a higher risk of progressive kidney damage and poorer long-term outcomes compared to those without ABAR antibodies.
The term ABAR is mainly used in research and clinical settings to identify a subgroup of lupus nephritis patients who might require more aggressive treatment strategies. It helps physicians in assessing disease severity and determining appropriate therapeutic interventions to manage the renal complications associated with lupus.
In conclusion, ABAR refers to a subset of lupus nephritis patients with autoantibodies against BILAG domains, which can indicate a higher risk for severe kidney damage in individuals with SLE.
