Abstract

Background Systemic Lupus Erythematosus (SLE) is an autoimmune systemic rheumatic disease that, in our area, presents hematologic manifestations in approximately 70% of cases1. Some of them are very rare, there are no large series whose analysis could provide relevant information.

Objectives To study the characteristics of patients with Pure Red Cell Aplasia (PRCA) in a large sample of SLE patients.

Methods SLE patients from RELESSER database were studied. We analysed the clinical and analytical SLE manifestations at 12 different domains (mucocutaneous, renal, musculoskeletal, constitutional, haematologic, vascular, cardiac, respiratory, neuropsychiatric, gastrointestinal, ophthalmic and serological) before, during and after PRCA diagnosis and until the last available assessment. We also studied activity (SELENA-SLEDAI) and damage (SLICC/ACR DI)indices at each of those times.

We evaluated the treatment received, PRCA recurrences and the number of deaths by this entity.

Results 3,656 patients from 45Rheumatology Units across Spain were studied. 5 cases of PRCA were found (<0.5%of total)

There were not viral infections in relation with the PRCA.

All patients had a good response to treatment, reaching complete remission without relapses or deaths. The mean number of treatment lines (± SD)that were necessary was 2.2 (±1.01)and the mean (± SD)number of treatments used was 2.8 (±1.92). Except for the patient diagnosed with PRCA before SLE, all of them received glucocorticoids as initial treatment. Of these 4patients only 1achieved complete remission without requiring immunosuppressive therapy.

The following table shows the characteristics of each patient:

Conclusions PRCA is a very rare cause of anemia in SLE. In most cases it appears several years after the diagnosis of SLE. It is a serious manifestation but in our series, with a proper management showed a favourable response.
