Abatacept has been approved by the FDA for use in reducing signs and symptoms of moderately to severely active polyarticular juvenile RA (juvenile idiopathic arthritis) in pediatric patients 6 years and older.  The approval was based on data from the AWAKEN study (Abatacept Withdrawal study to Assess efficacy and safety in Key Endpoints in juvenile idiopathic arthritis Not responding to current treatment), a 3-part study including an open-label extension in children with polyarticular juvenile RA.  Overall, the 3-part trial showed that abatacept therapy yielded improvements across 3 major subtypes of juvenile RA through 1 year in patients aged 6 to 17 years whose disorder had not responded to 1 or more DMARDs, such as methotrexate or tumor necrosis factor (TNF) antagonists.  Patients had a disease duration of approximately 4 years with moderately to severely active disease at study entry, as determined by baseline counts of active joints (mean of 16) and joints with loss of motion (mean of 16); patients had elevated C-reactive protein (CRP) levels (mean of  mg/dL) and ESR (mean of 32 mm/h).

Recognition of these variants may have prognostic value in individuals with primary focal segmental glomerulosclerosis (. where no underlying cause is identified). The collapsing variant is associated with higher rate of progression to end-stage renal disease , whereas glomerular tip lesion variant has a low rate of progression to end-stage renal disease in most patients. Cellular variant shows similar clinical presentation to collapsing and glomerular tip variant but has intermediate outcomes between these two variants. However, because collapsing and glomerular tip variant show overlapping pathologic features with cellular variant, this intermediate difference in clinical outcomes may reflect a sampling bias in cases of cellular focal segmental glomerulosclerosis (. unsampled collapsing variant or glomerular tip variant). The prognostic significance of perihilar and NOS variants has not yet been determined. The NOS variant is the most common subtype. Collapsing variant is the most common type of glomerulopathy caused by HIV infection.
