Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Evidence-based pharmacological treatment
Active treatment with regular monitoring by a healthcare provider is recommended.
Immunoglobulin replacement therapy
Regular intravenous or subcutaneous immunoglobulin infusions to provide passive immunity and compensate for deficient antibody production. This is the cornerstone of treatment for most forms of primary immunodeficiency affecting innate immunity.
Prophylactic antibiotics
Long-term antibiotic prophylaxis to prevent bacterial infections that patients with innate immune defects are susceptible to. Selection depends on specific pathogen risks and local resistance patterns.
Additional treatment options
Regular infection surveillance
Frequent monitoring for signs of infection with low threshold for investigation given the heightened infection risk in innate immune defects. Includes regular laboratory assessments and imaging as warranted.
monitoringInfection prevention practices
Strict adherence to hygiene measures including hand hygiene, food safety, and avoidance of known infectious exposures. Patient and family education on recognizing early infection signs.
lifestyleVaccination consultation
Careful review of vaccination status with administration of inactivated vaccines when appropriate. Live vaccines may be contraindicated depending on the specific genetic defect.
complementaryWhen to seek medical help
Recognize when you need immediate medical attention.
See a doctor within 24 hours
Moderate to severe symptoms that may indicate worsening of this condition. Prompt medical evaluation is recommended.
Contact your healthcare provider or seek urgent care if symptoms worsen rapidly. Go to the emergency department for life-threatening symptoms.
