Life-Threatening Severe Thrombocytopenia and Mild Autoimmune Hemolytic Anemia Associated with Brucellosis

Abstract

Methods. We report the case of a 73-year-old Saudi female who presented with severe thrombocytopenia and mild autoimmune hemolytic anemia associated with brucellosis. The coexistence of published cases of two hematological disorders with brucellosis is rare. Results. Despite the initial treatment with eltrombopag and intravenous immunoglobulin (IVIG), our patient’s platelets count remained low and significantly improved after initiation of brucellosis treatment in the form of rifampicin and doxycycline. Discussion. We conclude by reviewing the case that in many parts of Saudi Arabia, brucellosis remains a prevalent infection. Hence, it should be considered as a possible diagnosis in febrile individuals with no localizing indications and the presence of severe thrombocytopenia in acute febrile illness. Although it is a rare association, it could be related to brucellosis. Conclusion. This is our region’s first published case of severe thrombocytopenia and mild autoimmune hemolytic anemia associated with brucellosis. It contributes to the literature on the successful use of rifampicin and doxycycline to treat hematological disorders associated with brucellosis.
