# Alternative Treatment Approaches for IgG4-Related Disease
Corticosteroids (conventional first-line treatment)
Corticosteroids, particularly prednisone or prednisolone, are the first choice for IgG4-related disease. These medications suppress the inflammatory response and can often achieve remission, especially in early stages of the disease.
ProveniIncluded in official guidelines, or approved by EMA or FDA
Many patients achieve a good response to moderate doses. The goal is usually to gradually reduce the dose as the disease comes under control, because long-term use causes side effects. The response varies: some people can stop treatment, others require maintenance doses. Monitoring tests (blood, imaging) help determine whether the disease is under control.
Steroid-sparing agents (immunosuppressants)
When corticosteroids are ineffective, poorly tolerated, or when the dose cannot be further reduced without symptom recurrence, steroid-sparing agents are used. These are typically azathioprine, mycophenolate mofetil, or methotrexate.
ProveniIncluded in official guidelines, or approved by EMA or FDA
These medications work by suppressing the immune system and allow doctors to reduce the corticosteroid dose. They require regular blood tests and caution due to infection risks and other possible side effects.
Rituximab (anti-B-cell therapy)
Rituximab targets B cells, which are involved in IgG4 production. This monoclonal antibody is used in patients who do not respond to conventional treatment or who do not tolerate it well.
ResearchediPositive results in clinical studies, not yet standard treatment
Experience is growing, and multiple case reports and small studies show promising results, especially with repeated treatment. However, it is not considered standard first-line therapy, but rather an option after exhausting other possibilities. Efficacy and long-term safety are still being investigated.
Mycophenolate mofetil (MMF)
This immunosuppressant is widely used as a steroid-sparing agent and is known to be well tolerated compared to other options.
ProveniIncluded in official guidelines, or approved by EMA or FDA
Many patients can reduce their corticosteroid dose with this without relapse. It requires regular blood tests and caution with infections and pregnancy.
Azathioprine (AZA)
A classic immunosuppressant that has been used for decades in autoimmune diseases.
ProveniIncluded in official guidelines, or approved by EMA or FDA
Effective as a steroid-sparing agent. Requires regular monitoring of blood values and liver function, and can increase infections.
Tocilizumab (anti-IL-6 therapy)
This medication inhibits the inflammatory substance interleukin-6, which may play a role in IgG4-related disease.
ResearchediPositive results in clinical studies, not yet standard treatment
Some case reports and small open-label studies suggest potential benefit, especially in patients who respond poorly to conventional treatment. Its place in the treatment regimen and long-term effects are not yet well established.
Abatacept (CTLA4-Ig)
This co-stimulation blocking agent interferes with T-cell activation, which can help suppress the immune response.
ResearchediPositive results in clinical studies, not yet standard treatment
Only a few case reports available; no strong evidence to date, but being investigated in certain scenarios.
Chinese herbal medicine / traditional remedies
Online and in alternative clinics, reports circulate about Chinese herbal therapies, sometimes as "natural" or "complementary" approaches.
UnproveniNo scientific evidence that it works
For IgG4-related disease specifically, no solid scientific evidence is available. Some general anti-inflammatory herbs have been studied in vitro, but this does not automatically translate to effectiveness in this complex autoimmune disease. Depending on the content, certain herbs may also have interactions with immunosuppressants or other medications.
Dietary interventions and lifestyle adjustments
Some patient groups promote diets aimed at reducing inflammation (e.g., low-FODMAP, elimination diets) or supplements (vitamin D, omega-3, probiotics).
UnproveniNo scientific evidence that it works
For IgG4-related disease specifically, good research is lacking. General anti-inflammatory nutrition can contribute to overall wellbeing, but should never replace regular treatment. Some diets can also be harmful (e.g., nutritional deficiency) or cause interactions.
Homeopathy
Homeopathic preparations are sometimes offered as "support" or "natural alternative".
Advised againstiProven ineffective or harmful, or dangerous in combination with your treatment
Homeopathy has no scientific evidence for effectiveness in IgG4-related disease or any other condition. Worse still: relying on homeopathy instead of proven treatment can lead to disease progression, serious complications (e.g., airway stenosis, kidney damage) and delayed investigation. The disease requires regular follow-up and rapid response to relapse.
Hyperbaric oxygen therapy (HBOT)
Occasionally promoted for autoimmune diseases with "improved circulation" and "inflammation reduction".
Advised againstiProven ineffective or harmful, or dangerous in combination with your treatment
For IgG4-related disease, no evidence exists. Moreover, HBOT can be risky when combined with certain medications and provides no benefit alongside standard treatment. There is a risk that patients seek this instead of, or delay, essential diagnostics and immunosuppression.
Stem cell therapy and experimental biologics outside evaluated protocols
Offers of "stem cell cures" circulate on the internet in countries with less regulation.
Advised againstiProven ineffective or harmful, or dangerous in combination with your treatment
There is no evidence whatsoever that stem cell therapy cures IgG4-related disease. On the contrary: the risks (infections, distorted immune response, financial harm) are real, and patients can lose precious time when proven treatment would be more effective. These therapies are not yet part of clinical trials with ethical review.
