First-line treatments
Infection prophylaxis
Prophylactic antibiotics and antifungal medications reduce the risk of opportunistic infections in immunocompromised patients. Regimens are tailored to individual risk factors and pathogen exposure.
Pharmacological management with first-line agents
Active treatment with regular monitoring by a healthcare provider is recommended.
Immunoglobulin replacement therapy
IVIG supplementation provides passive humoral immunity to compensate for antibody deficiencies. Regular infusions help maintain protective antibody levels and reduce infection frequency.
Additional treatment options
Hematopoietic stem cell transplantation
HSCT offers potential curative therapy by restoring functional T-cell immunity. This intensive procedure is considered for severe cases with poor prognosis on conventional management.
surgicalInfection prevention measures
Strict hand hygiene, food safety practices, and avoidance of crowded indoor spaces significantly reduce infection risk. Patient education on recognizing early infection signs is essential.
lifestyleImmune function monitoring
Regular assessment of lymphocyte subsets, immunoglobulin levels, and clinical infection burden guides treatment decisions. Frequency increases during active management changes.
