An allergic reaction called serum sickness occurs when a foreign protein or antigen is introduced into the body and causes a delayed reaction. In this blog post, we'll explore the causes, symptoms, diagnosis, treatment, and prevention strategies related to serum sickness. These antigens can trigger an immune response, causing a range of symptoms.
In most cases, serum sickness is caused by the introduction of foreign proteins or antigens into the body, often through medications, vaccinations, or animal proteins.
Antibiotics (e.g., penicillin), antiserums (e.g., snake antivenom), and monoclonal antibodies (e.g., rituximab) can induce serum sickness.
Some vaccines, especially those containing foreign proteins or antigens, may trigger serum sickness in susceptible individuals.
Insect stings, bites, or animal-derived products can also expose you to animal proteins.
Within one to three weeks after exposure to the triggering antigen, serum sickness symptoms may include:
Chills and fever
Itching, rashes, or hives
Swelling and pain in the joints
Weakness and muscle aches
Lymph nodes swollen
Malaise and fatigue
A thorough medical history, physical examination, and evaluation of symptoms are all required to diagnose serum sickness. An elevated level of C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), or immunoglobulin E (IgE) may also be a sign of inflammation and allergic response. To identify specific triggers, skin testing or allergy tests may be conducted.
The treatment of serum sickness aims to alleviate symptoms and prevent complications. Some common treatment approaches are:
Remove the source of the immune response, such as stopping the offending medication or avoiding further exposure to the triggering antigen.
Itching, rash, and joint pain can be relieved with over-the-counter medications, such as antihistamines (e.g., diphenhydramine) and nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen.
Serum sickness can be treated with oral or intravenous corticosteroids to reduce inflammation and suppress the immune system.
Serum sickness can be managed effectively with adequate hydration, rest, and supportive measures.
A few preventive strategies include minimizing exposure to known triggering antigens and taking precautions when receiving medications or vaccines.
Prior to receiving medications or vaccines, allergy testing or skin testing is undertaken to identify potential allergens or triggers.
Providing a detailed medical history to healthcare providers and informing them of known allergies and adverse reactions.
Following recommended immunization schedules and discussing any concerns or allergies with your healthcare provider before receiving vaccines.
Wearing protective clothing and using insect repellent when outdoors is one way to avoid insect stings or bites.
