Case Report: Tuberculosis-Induced Autoimmune Hemolytic Anemia

Area of Science:

• Hematology
• Infectious Diseases
• Immunology

Background:

• Tuberculosis (TB) is a significant global infectious disease with diverse clinical manifestations.
• Hematological complications, such as anemia of chronic disease, are common in TB.
• Autoimmune hemolytic anemia (AIHA) is a rare but documented hematological sequela of TB.

Observation:

• A female patient presented with refractory AIHA, a severe form of red blood cell destruction.
• The refractory AIHA was ultimately attributed to disseminated tuberculosis.
• This highlights the importance of considering TB in unexplained AIHA cases.

Findings:

• The patient's refractory AIHA showed a significant positive response to a multi-modal treatment approach.
• Treatment included corticosteroids, standard anti-tuberculosis medications, and the targeted immunotherapy rituximab.
• This combination therapy effectively managed both the AIHA and the underlying disseminated TB.

Implications:

• This case underscores the potential for disseminated TB to manifest as refractory AIHA.
• It demonstrates the efficacy of a combined treatment strategy involving immunosuppression and anti-infective therapy.
• Further research into the immunological mechanisms linking TB and AIHA may reveal new therapeutic targets.
