Overview
Currently, there is no standard curable treatment for Autoimmune lymphoproliferative syndrome ALPS. Treatment of different features of ALPS as cytopenias, autoimmune syndromes as well as monitoring and treating the consequences as splenomegaly, lymphoma can be helpful.
Treatment
- Mostly commonly directed at autoimmune disease
- Maybe needed to treat bulky lymphoproliferation
- First line therapies
- Corticosteroids
- Very active but toxic with chronic use
- IVIgG
- Not as effective as in other immune cytopenia syndromes
- Corticosteroids
- Second line therapies
- Mycophenolate mofetil (cellcept)[1]
- Inactivates inosine monophosphate
- Active in most patients
- Most studied medicine in clinical trials
- Some patients have complete resolution of autoimmune disease
- Some patients have partial responses
- Some patients relapse
- Does not affect lymphoproliferation or reduce DNTs
- Well-tolerated: Side effects: Diarrhea, neutropenia
- Does not require therapeutic drug monitoring
- No drug-drug interactions
- Can cause hypogammaglobulinemia (transient) requiring IVIgG replacement
- Consider PCP prophylaxis but usually not needed
- Sirolimus (rapamycin, rapamune)
- mTOR (mammalian target of rapamycin) inhibitor[2]
- Active in most patients
- Second most studied agent in clinical trials
- Most patients have complete resolution of autoimmune disease (>90%)[3] [4]
- Most patients have complete resolution of lymphoproliferation, including lymphadenopathy and splenomegaly (>90%)
- Some patients have near complete response (disease flares with viral illness)
- A few patients have had partial responses (most commonly patient with non-cytopenia autoimmune disease)
- Most patients have elimination of peripheral blood DNTs
- mTOR/Akt/PI3K pathway may be activated in abnormal ALPS cells: mTOR inhibitors may be targeted therapy
- May not be as immune suppressive in normal lymphocytes as other agents. Some patients have had improvement in immune function with transition from cellcept to rapamycin[5]
- Not reported to cause hypogammaglobulinemia
- Hypothetically, may have lower risk of secondary cancers as opposed to other immune suppressants
- Always a risk with any agent in pre-cancerous syndrome as immune suppression can decreased tumor immunosurvellence
- mTOR inhibitors active against lymphomas, especially EBV+ lymphomas. Thus, THEORETICALLY could eliminate malignant clones.
- Requires therapeutic drug monitoring
- Goal serum trough 5-15ng/ml
- Drug-drug interactions
- Well tolerated: Side effects: mucositis, diarrhea, hyperlipidemia, delayed wound healing
- Consider PCP prophylaxis but usually not needed
- Other agents:
- Fansidar,[6] [7] mercaptopurine: More commonly used in Europe. Good ancedotal data
- Rituximab: AVOID. Can cause life long hypogammaglobulinemia[8]
- Splenectomy: AVOID. >30% risk of pneumococcal sepsis even with vaccination and antibiotic prophylaxis[9] [10]
- Mycophenolate mofetil (cellcept)[1]
