Lupus Nephritis in Indian Children: Flares and Refractory Illness

ABSTRACT

Objective: To evaluate the incidence of flares and treatment resistance in children with lupusnephritis and their association with renal outcomes. Methods: We retrospectively reviewedthe case records of 34 children treated for lupus nephritis (Class II-IV) at a single center.Patients were followed for a minimum of five years to evaluate treatment response, onset offlares, and renal survival. Regression analyses were performed to identify the factorsassociated with treatment refractoriness, incidence of flares and renal survival. Results: Theincidence of flares was 0.16 episodes/person/year. Eight patients (23.5%) were refractory totreatment. The five-year renal survival was 79%. Multiple episodes of flares (P=0.028) andtherapy refractoriness (P=0.003) were associated with poor renal survival. Conclusions:Prevention and aggressive management of renal flares is expected to prevent progression toend stage renal disease in lupus nephritis.
