3

Anti-inflammatory therapy

Targeted anti-inflammatory medications to reduce excessive immune activation when elevated HLA-DR expression indicates pathologic immune response.

medication

Additional treatment options

Corticosteroid therapy (short-term)

Brief course of corticosteroids may be indicated in acute settings with severe immune activation, followed by careful tapering.

medication

Leukapheresis (if indicated)

Selective removal of activated immune cells from circulation in severe cases of immune dysregulation refractory to pharmacological management.

procedure

Immune-supportive lifestyle modifications

Implementation of balanced exercise routines, smoking cessation, and alcohol moderation to reduce exogenous factors contributing to immune activation.
