Overview
The mainstay of management for eosinophilic granulomatosis with polyangiitis is glucocorticoids and cyclophosphamide. Immunosupressive agents (eg, azathioprine and methotrexate) can be used for maintenance therapy. Rituximab, interferon-alpha, anti IgE antibodies and plasma exchange can be used as a second line therapies in the management of eosinophilic granulomatosis with polyangiitis.
Medical Therapy
- Medical therapy for eosinophilic granulomatosis with polyangiitis is according to the guidelines proposed by:[1][2]
- EGPA Consensus Task Force recommendations by EULAR (European League Against Rheumatism)
- American College of Rheumatology (ACR)
- Pharmacologic therapy for EGPA include systemic glucocorticoids(eg, prednisone), immunosupressive agents (eg, cyclophosphamide, azathioprine, methotrexate), inhaled glucocorticoids, IVIG (intravenous immune globulin), anti-IgE (eg, omalizumab), anti-IL-5 antibodies (eg, mepolizumab), and plasma exchange.
- Five factor score(FFS) and Birmingham vasculitis activity score (BVAS) can be used to assess the vasculitis severity and disease activity. These two scoring systems can be helpful in initiating therapy.[3][4]
Initiating pharmacotherapy
Systemic glucocorticosteroids
- The first line treatment for all the patients with eosinophilic granulomatosis with polyangiitis are systemic glucocorticoids. Most commonly used drug is prednisone.[1][5][6]
- Preferred regimen:
- Oral dose of 0.5 to 1.0 mg/kg/day for 2-3 weeks then gradual tapering the dose to 0.3 mg/kg/day after 3 months and 0.15 mg/kg/day after 6 months.
- Higher doses of corticosteroids can be given in pulses up to 7.5-15mg/kg/day may be required in severe vasculitis involving heart, kidney, and GIT.
- For life-threatening vasculitis, intravenous glucocorticoids can be administered.
- Preferred regimen: 1 gm/day/3 days followed by treatment with oral glucocorticoids 0.5-1 mg/kg/day.
- Once remission is achieved, dose is gradually tapered over months. Patients who achieve remission will require long term low dose of corticosteroids.
- Most common side effects:
Cyclophosphamide
- Cyclophosphamide can be admistered in EGPA patients with severe and life threatening multiple organ involvement in addition to glucocorticoids.[7][8]
- Preferred regimen:
- Oral therapy: 2 mg/kg/day
- Intravenous pulses: For first 3 doses 15 mg/kg/every 2 weeks, for 4-6 doses 15 mg/kg/ every 3 weeks.
- Common side effects:
- Severe drug induced neutropenia
- Opportunistic infection
- Gonadal toxicity
- Low renal clearance
Maintenance therapy
- Once induction of remission has occured, maintenance therapy with azathioprine or methotrexate can be recommended.[5]
- Maintenance with cyclophosphamide is associated with frequent relapses.
- Preferred regimen: 10-30 mg/day for 12-18 months.
- Folic acid supplementation is necessary during immunosuppressant therapy.
Additional therapy
Rituximab
- Administration of rituximab can be beneficial in ANCA positive patients with progressieve renal failure, CNS involvement, and refractory disease.[9]
Interferon-alpha
- Second line therapy drug, may be useful for patients who are not responding to glucocorticoids or immunosuppressieve agents[10]
- Preferred regimen: Subcutaneous administration of 3 million I.U./3 times weekly
- Relapses are more frequent
Anti-IgE therapy
- Omalizumab may be administered to control asthma, sinusitis and eosinophilia refractory to systemic and inhaled glucocorticoids.[11]
Anti-IL-5 antibodies
- Mepolizumab: Preferred regimen: 300mg given every 4 weeks.
Inhaled glucocorticoids
- They can be used to relieve symptoms of upper airway disease.
Intravenous immunoglobulins
- High doses of intravenous immunoglobulins may be considered in patients whose flare are refractory to standard therapy and during pregnancy.[12]
- Preferred regimen: 2 g/kg for 2–5-day cycles for every 3-4 weeks.
Plasma exchange
- The benificial role of plasma exchange in addition to glucocorticoid or immunosuppressieve therapy to improve survival rate in patients with eosinophilic granulomatosis with polyangiitis is unclear.[13]
- Plasma exchange may be considered for patients with severe and rapidly progressieve renal failure, and diffuse alveolar hemorrhage.[14]
