From the Guidelines
Sarcoidosis treatment should prioritize reducing morbidity and mortality risk, as well as improving quality of life (QoL), with corticosteroids as the first-line treatment for symptomatic disease. The management of sarcoidosis can be challenging, and the clinician must consider various manifestations of the disease, both initially and over time 1. The outcome of the disease is variable, with some patients having a very good outcome and never requiring treatment, while less than 10% of patients die, mostly from advanced lung disease 1.
Treatment Approach
For mild cases with minimal symptoms, observation alone may be sufficient. However, for symptomatic disease, corticosteroids are the first-line treatment, typically starting with prednisone 20-40mg daily for 1-3 months, followed by a slow taper over 6-12 months 1. In cases requiring steroid-sparing agents, methotrexate (10-25mg weekly), hydroxychloroquine (200-400mg daily), or azathioprine (50-200mg daily) may be used.
Severe or Refractory Disease
For severe or refractory disease, TNF-alpha inhibitors like infliximab (3-5mg/kg IV at weeks 0,2, and then every 4-8 weeks) can be effective 1. Pulmonary sarcoidosis often requires treatment when pulmonary function tests show restriction or when symptoms like cough and dyspnea are present. Cardiac sarcoidosis, neurosarcoidosis, and ocular disease typically warrant aggressive treatment due to potential serious complications.
Disease Pathophysiology and Monitoring
The disease pathophysiology involves an exaggerated immune response to unknown antigens, with CD4+ T-cells and macrophages forming the characteristic non-caseating granulomas. Regular monitoring of organ function, medication side effects, and disease progression is essential for optimal management 1. The majority of studies regarding treatment of symptomatic sarcoidosis have focused on pulmonary disease, but several studies have evaluated other manifestations such as skin, heart, and neurologic disease 1.
Key Considerations
- The indications for treatment remain unclear and mostly based on a case-by-case basis 1
- Measurements of response to treatments are still too heterogeneous 1
- Clinical trials may provide more information 1
- Single end-points are often used, which may not fully capture the complexity of the disease 1
From the Research
Treatment Options for Sarcoidosis
- Corticosteroids are the primary treatment for sarcoidosis, but their long-term use can lead to severe side effects 2, 3
- Second-line treatment options include cytotoxic agents such as methotrexate, azathioprine, leflunomide, and hydroxychloroquine 2, 4, 5
- Third-line treatment options include tumor necrosis factor-alpha inhibitors like infliximab and adalimumab, as well as experimental therapies like rituximab 2, 4, 6
Factors Influencing Treatment Choice
- The decision to treat sarcoidosis depends on the severity of symptoms and the risk of organ damage 3, 6
- Treatment strategies often follow a progression, with corticosteroids as the initial treatment and second-line and third-line therapies added as needed 4, 6
- Patient-specific factors, such as the presence of polymorphisms, may influence treatment response and toxicity 2
