Understanding Inflammation in PANDAS
Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections (PANDAS) is a condition where a Group A Streptococcus infection triggers a misdirected immune response. This response is believed to produce autoantibodies that target the basal ganglia of the brain, leading to inflammation and a sudden onset or worsening of symptoms such as obsessive-compulsive disorder (OCD), tics, and anxiety. Because neuroinflammation is at the heart of the symptoms, anti-inflammatory therapies are a crucial part of the comprehensive treatment approach. The "best" anti-inflammatory is not a single drug but rather a tailored choice based on the child's specific presentation, disease severity, and overall health. A multi-pronged approach that includes treating the underlying infection, managing symptoms, and using immune-modulating strategies is often necessary.
First-line anti-inflammatory treatments: NSAIDs
For mild to moderate flares, Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) like ibuprofen or naproxen are often the initial anti-inflammatory treatment recommended. These over-the-counter medications can be particularly helpful for exacerbations that occur in the weeks following immunotherapy.
How NSAIDs help with PANDAS
NSAIDs work by inhibiting the body's production of prostaglandins, which are compounds that promote inflammation, pain, and fever. By reducing systemic inflammation, NSAIDs can help alleviate the neuroinflammation thought to contribute to PANDAS symptoms. A study published in 2017 found that NSAIDs given early in a flare might shorten the duration of neuropsychiatric symptoms. The PANDAS Physicians Network suggests that while NSAIDs may not be as effective as other treatments for severe cases, they can be a helpful tool for symptom relief, particularly in less severe flares.
Key considerations for NSAIDs
While generally well-tolerated, NSAIDs carry risks, including potential gastrointestinal side effects like stomach pain and irritation, as well as risks to the heart and kidneys. They should always be used under the supervision of a physician, especially concerning correct dosage and duration of therapy. The cyclo-oxygenase inhibitor celecoxib is another NSAID that has been reported to be helpful.
More potent options: Corticosteroids and IVIG
For more severe or persistent symptoms, stronger anti-inflammatory and immunomodulatory treatments may be necessary. Corticosteroids and Intravenous Immunoglobulin (IVIG) are two such options.
Corticosteroids
Corticosteroids, such as prednisone, are powerful anti-inflammatory agents that suppress the immune system. Some studies have shown that corticosteroids given early in a flare may shorten symptom duration and lead to more durable remissions. However, their use requires careful consideration. A significant concern is that corticosteroids can sometimes temporarily worsen emotional and behavioral symptoms, including aggression and mood swings. For this reason, and due to other potential side effects with long-term use, their application is often limited to short bursts and under close medical supervision.
Intravenous Immunoglobulin (IVIG)
IVIG is a therapy that involves the infusion of a high dose of pooled human antibodies to help modulate the immune system. It is typically reserved for children with severe or refractory symptoms that have not responded to first-line treatments. The anti-inflammatory mechanisms of IVIG are not fully understood, but it is believed to help neutralize the misdirected autoantibodies and "retrain" the overactive immune response. Clinical studies have indicated that IVIG can significantly reduce symptom severity in PANDAS and PANS patients. However, it is an expensive and invasive procedure that can cause side effects like headaches, fatigue, and nausea.
Complementary approaches and supplements
In addition to medical treatments, some families incorporate dietary changes and supplements to help manage inflammation. An anti-inflammatory diet that reduces processed foods, sugars, and potential allergens like gluten and dairy is often recommended.
Supplements with anti-inflammatory properties
- Omega-3 Fatty Acids: Found in fish oil, omega-3s are known to reduce inflammation and support brain function.
- Curcumin: The active compound in turmeric, curcumin has potent anti-inflammatory effects.
- Vitamin D: Research has revealed that many PANDAS patients have a Vitamin D deficiency, and supplementation may play a role in modulating immune function.
While these natural options can be beneficial, they should be used as complementary strategies under the guidance of a healthcare provider rather than as a replacement for conventional medical treatment.
Comparison of Anti-inflammatory Therapies for PANDAS
| Therapy | Use Case | Reported Effectiveness | Key Considerations |
|---|---|---|---|
| NSAIDs (Ibuprofen, Naproxen) | Mild to moderate flares, post-immunotherapy exacerbations. | Moderate for symptom relief and potentially shortening flares. | Readily available, but requires medical guidance for dosing and duration due to GI side effect risk. |
| Corticosteroids | Moderate to severe flares, potentially hastening symptom resolution. | Potentially effective, with studies showing shortened flare durations. | Can temporarily worsen behavior and has significant side effects, requiring cautious, short-term use. |
| Intravenous Immunoglobulin (IVIG) | Severe, refractory cases unresponsive to first-line treatment. | Moderate to high for significant symptom reduction or remission. | Invasive, very high cost, potential for side effects like headache, and not always covered by insurance. |
| Dietary Strategies & Supplements | Complementary, long-term support for immune health and inflammation. | Anecdotal or supportive, not a primary treatment. | Generally safe but should not replace conventional therapy; requires consistency. |
Conclusion: Finding the optimal anti-inflammatory approach
There is no single best anti-inflammatory for PANDAS; rather, the optimal strategy is personalized and often evolves over the course of the condition. For mild-to-moderate flares, short courses of NSAIDs like ibuprofen are a common starting point, but they must be used under medical direction. In more severe or treatment-resistant cases, therapies like corticosteroids or IVIG may be considered, but they come with increased risks and complexity. Complementary approaches such as an anti-inflammatory diet and certain supplements can provide additional support. The selection of an anti-inflammatory regimen is a critical decision that requires close collaboration with healthcare professionals experienced in treating PANDAS, often involving a team of specialists to address both the immune and neuropsychiatric aspects of the disorder. Early and proactive treatment, including addressing the underlying strep infection, is key to managing the condition and improving outcomes.

Choosing the right anti-inflammatory for PANDAS
- Prioritize professional guidance: The choice of anti-inflammatory should always be made in consultation with a qualified medical professional, preferably one experienced in PANDAS.
- Start with conservative options: For mild-to-moderate flares, oral NSAIDs like ibuprofen or naproxen are often the first step, but their use requires caution due to potential side effects.
- Consider potent treatments for severe cases: Intravenous Immunoglobulin (IVIG) and corticosteroids are reserved for severe, refractory cases, and the benefits must be weighed against their higher risks and costs.
- Supplement with complementary strategies: An anti-inflammatory diet and supplements like Omega-3s can support overall immune health but are not a substitute for primary medical treatment.
- Address the root cause: While anti-inflammatories address symptoms, treating the underlying strep infection with antibiotics is a crucial part of managing PANDAS.
- Weigh risks vs. benefits: Each anti-inflammatory option has a different risk profile. For example, corticosteroids can temporarily worsen behavior in some children.
- Monitor closely: Regardless of the treatment chosen, close monitoring is necessary to assess effectiveness and manage potential side effects.
