Table 1. Platelet Count, White Blood Cells, Red Blood Cells, Anti-DNA and Complement According to Exposure to and Interruption of Hydroxychloroquine (HCQ).

Hydroxychloroquine is used in the long-term therapy of systemic lupus erythematosus (SLE). Although considered to be a safe treatment, side effects have been documented. An uncommon side effect is thrombocytopenia. In order to establish the diagnosis of thrombocytopenia secondary to Hydroxychloroquine, non-pharmacological causes must be ruled out and it is necessary to determine a recurrence after re-exposure to the drug. We present one case of severe thrombocytopenia occurring in a patient with SLE undergoing treatment with Hydroxychloroquine.

Systemic lupus erythematosus

La hidroxicloroquina es un fármaco antimalárico, empleado como terapia a largo plazo en el lupus eritematoso sistémico (LES). A pesar de considerarse un tratamiento seguro, existen efectos adversos descritos. Uno muy infrecuente es la trombocitopenia. Para establecer el diagnóstico de trombocitopenia causada por hidroxicloroquina es necesario descartar otras causas no farmacológicas y objetivar la recurrencia tras la reexposición al fármaco. Presentamos un caso de trombocitopenia severa en un paciente con LES durante el tratamiento con hidroxicloroquina.
