    Summary

    A Mycoplasma pneumoniae infection triggered a rare anti-Pr antibody, causing severe autoimmune hemolytic anemia in a 41-year-old man. Despite treatment, the rapid and fatal hemolysis led to death within five days.

    Area of Science:

    • Hematology
    • Immunology
    • Infectious Diseases

    Background:

    • Mycoplasma pneumoniae infections can occasionally trigger autoimmune phenomena.
    • Autoimmune hemolytic anemia (AIHA) is a condition where the immune system attacks red blood cells.

    Observation:

    • A 41-year-old man developed an anti-Pr antibody following Mycoplasma pneumoniae infection.
    • The patient presented with livedo reticularis as an initial warning sign.
    • A severe autoimmune hemolytic reaction rapidly ensued within five days.

    Findings:

    • The autoantibody exhibited broad thermal reactivity from 4°C to 37°C.
    • Massive whole blood exchanges were ineffective in halting the hemolytic process.
    • The patient succumbed to hemolysis and uremia on the fifth day of admission.

    Implications:

    • This case highlights a rare and aggressive autoimmune complication of Mycoplasma pneumoniae.
    • The broad thermal range of the autoantibody may contribute to its severity.
    • Understanding such rare antibody-mediated reactions is crucial for diagnosing and managing severe AIHA.
