What are the recommended treatment options for outpatient management of enthesophytes?

Outpatient Treatment of Enthesophytes

For outpatient management of enthesophytes, initiate treatment with NSAIDs as first-line therapy, combined with local glucocorticoid injections to the affected enthesis and physical therapy, reserving biological DMARDs for cases that fail to respond to these initial measures. 1

First-Line Treatment Approach

NSAIDs as Primary Therapy

• NSAIDs are the recommended initial pharmacological treatment for enthesopathy in the outpatient setting. 2, 1
• Treatment should continue for at least 3 months at maximal recommended or tolerated anti-inflammatory doses unless contraindicated. 2
• Patients must have adequate therapeutic trials of at least two different NSAIDs before escalating therapy. 2

Local Glucocorticoid Injections

• Local glucocorticoid injections directed to the site of inflammation are conditionally recommended for active enthesitis despite NSAID treatment. 2, 1
• Injections at sites such as the greater trochanter, pelvic rim, and plantar fascia attachment can be considered based on symptom severity. 2
• Critical caveat: Avoid peri-tendon injections around the Achilles, patellar, and quadriceps tendons due to high risk of tendon rupture. 2

Non-Pharmacological Interventions

• Physical therapy and supervised exercise programs are strongly recommended as part of the treatment regimen. 2, 1
• Regular exercise should be incorporated into the management plan. 1

Second-Line Treatment Options

Conventional DMARDs

• Sulfasalazine may be considered specifically for peripheral enthesitis, though evidence shows inconsistent results. 1
• Conventional synthetic DMARDs have limited efficacy specifically for enthesitis and are not routinely recommended for isolated enthesopathy. 1

Third-Line Treatment: Biological Therapy

When to Escalate

• Biological DMARDs should be considered when NSAIDs and local injections provide insufficient relief. 1
• All biological DMARDs demonstrate similar efficacy for enthesitis. 1

Biological Agent Options

• TNF inhibitors (infliximab, etanercept, adalimumab) are established options. 1
• IL-17 inhibitors and IL-12/23 inhibitors are alternative biological therapies. 1

Special Considerations for Outpatient Management

Diagnostic Differentiation

• Distinguish true inflammatory enthesitis from mechanical enthesopathy or widespread pain syndromes before initiating treatment. 1
• Evaluate for asymmetrical pattern of painful entheses, which suggests inflammatory enthesitis. 1
• Assess for concomitant fibromyalgia, which can complicate assessment and cause overestimation of disease severity. 1

Alternative Therapy for Refractory Cases

• Low-dose radiation therapy is a highly effective option with minimal side effects for painful plantar enthesophytes that fail conservative management. 3
• Duration of pain before treatment initiation is a significant prognostic factor—earlier integration of radiation therapy results in superior pain reduction. 3
• At long-term follow-up, 73% of patients achieved complete pain relief with radiation therapy. 3

Context-Specific Treatment Algorithms

For Spondyloarthritis-Associated Enthesopathy

• Follow the treatment ladder from NSAIDs to biological DMARDs as outlined above. 1
• TNF inhibitors are specifically recommended for inadequate response to NSAIDs in ankylosing spondylitis patients. 1

For Psoriatic Arthritis-Associated Enthesopathy

• Apply the same stepwise approach from NSAIDs through biological DMARDs. 1
