Pure red cell aplasia in systemic lupus erythematosus

Area of Science:

• Hematology
• Immunology
• Rheumatology

Background:

• Pure red cell aplasia (PRCA) is a rare disorder causing severe anemia.
• PRCA can be associated with autoimmune diseases like systemic lupus erythematosus (SLE).
• PRCA in SLE patients is difficult to manage with high mortality, and optimal treatment lacks consensus.

Purpose of the Study:

• To report the first case of PRCA in an SLE patient treated successfully with splenectomy.
• To evaluate splenectomy as a therapeutic option for corticosteroid-refractory PRCA in SLE.

Main Methods:

• Case report of a patient with SLE who developed PRCA.
• Initial treatment with prednisone and intravenous gamma globulin.
• Subsequent splenectomy for refractory PRCA.

Main Results:

• The patient achieved complete resolution of PRCA following splenectomy.
• Normal hemoglobin levels were maintained for 3 years post-splenectomy without further therapy.
• This is the 14th reported case of PRCA in SLE and the first treated with splenectomy.

Conclusions:

• Splenectomy can be an effective treatment for PRCA in patients with SLE.
• Consider splenectomy for managing corticosteroid-refractory PRCA in SLE patients.
