Catastrophic antiphospholipid syndrome after pregnancy complicated by hemolysis, elevated liver enzymes and low platelets syndrome.

Background: Antiphospholipid syndrome (APLS) is rarely complicated by catastrophic antiphospholipid syndrome (CAPS). Peripartum CAPS is rarer still and can masquerade as other obstetric disorders. A high degree of suspicion is critical for early diagnosis and specific management given the significant morbidity and mortality associated with this disorder.

Case: We report a case of a 27-year-old at 22 week's gestation with a history of APLS found to have severe hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome, resulting in termination of pregnancy. Further workup revealed the diagnosis of CAPS followed by prompt treatment with triple therapy leading to clinical improvement.

Conclusion: CAPS should be considered within the differential in an obstetric patient with a history of APLS who has evidence of multiorgan involvement with macro- or microvascular thrombosis. Although this may mimic alternative disorders, prompt diagnosis is imperative for appropriate therapy and reduction in maternal morbidity and mortality.
