La prevalencia del síndrome de antifosfolípidos en pacientes con lupus eritematoso sistémico en el Hospital Universitario de Puerto Rico / Prevalence of antiphospholipid syndrome in patients with systemic lupus erythematosus at the University Hospital of Puerto Rico

ABSTRACT

This is a retrospective study based on a population of 80 patients with connective tissue diseases from the University Hospital of Puerto Rico. Among the population, 62 (77.5) of the patients had Systemic Lupus Erythematosus (SLE), whom we were most interested to monitor. The investigation revealed an incidence of 13.8 of anthiophospholipid syndrone within the general population. Among the patients with SLE it was 12.9, and only 5.5 among the population with other diagnoses. The antibody found with the highest frequency within the systemic lupus erythematosus population was the anticardiolipin IgG (30.6) and lupus anticoagulant (17.7). The antibody frequency among patients with other diagnoses was only 5.5 for lupus anticoagulant and 5.5 for anticardiolipin IgM (the only one found). Among SLE's clinical manifestations, the most frequently found were thrombocitopenia and pregnancy complications.
