Development of exclusively cutaneous sarcoidosis in patient with rheumatoid arthritis during treatment with etanercept

An update on the diagnosis and management of ocular sarcoidosis

PURPOSE OF REVIEW

Ocular sarcoidosis is one of the most common causes of uveitis worldwide. The diagnosis and treatment of patients with ocular sarcoidosis remains challenging in some cases. It is important for clinicians to keep up to date with new diagnostic and treatment tools for this disease.

RECENT FINDINGS

The International Workshop on Ocular Sarcoidosis diagnostic criteria were first proposed in 2009 and revised in 2017. The new criteria contained two parts: ocular presentation and systemic investigation. The diagnostic value of liver enzymes was reduced in the new criteria, whereas the value placed of lymphopenia and the CD4/CD8 ratio in bronchoalveolar lavage fluid were increased. Despite not being included in the criteria, recent studies have also highlighted the diagnostic value of serum soluble interleukin-2 receptors. Recent ophthalmologic imaging also provides useful insights for the differential diagnosis.Many new treatments for ocular sarcoidosis have been developed in recent years. The introduction of biological immunomodulatory agents for uveitis treatment represents a big improvement. Antitumor necrosis factor-alpha antibodies, including adalimumab, have been proven to be effective for treating ocular sarcoidosis. Many studies have also suggested that other biological agents could be effective and well tolerated. Newer intravitreal dexamethasone and fluocinolone implants have been developed. Patients treated with these implants have experienced good and sustained control of their intraocular inflammation.

SUMMARY

Diagnosis and treatment options for ocular sarcoidosis have changed over time. However, challenges still exist in some difficult patients. Future studies should focus on finding more sensitive biomarkers and developing more effective immunomodulatory treatments with longer efficacy and less side effects.

Systemic Sarcoidosis Associated with Certolizumab Pegol Treatment for Rheumatoid Arthritis: A Case Report and Review of the Literature

A 69-year-old woman presented with appetite loss, fatigue, and a low-grade fever. She had been receiving certolizumab pegol for rheumatoid arthritis for six years. Computed tomography of the chest showed multiple micronodules in both lungs and bilateral hilar and mediastinal lymphadenopathy. An ophthalmic examination showed the findings of uveitis. Lymphocytosis with an increased CD4/CD8 ratio was seen in the bronchoalveolar lavage fluid. Video-assisted thoracoscopic biopsy specimens obtained from the right lung and a right hilar lymph node showed noncaseous epithelioid cell granulomas. Anti-tumor necrosis factor-α-induced sarcoidosis was diagnosed, and she was successfully treated with cessation of certolizumab pegol and systemic corticosteroid therapy.

Necrotizing Granulomas in a Patient With Psoriasis and Sarcoidosis After Adalimumab-Medication-Induced Reaction or Reactivation of Latent Disease?

In this report, we describe a case of a patient with a clinical history of systemic sarcoidosis and psoriasis who developed biopsy-confirmed perforating and necrotizing cutaneous granulomas after 12 months of treatment with adalimumab, a tumor necrosis factor-alpha-inhibiting, anti-inflammatory, biologic medication, prescribed for the patient's psoriasis. Although rare reports of a "sarcoidosis-like" reaction associated with select tumor necrosis factor-alpha agents exist, to the best of our knowledge, perforating and necrotizing cutaneous granulomas after treatment with adalimumab has not been previously reported. Given the patient's history of systemic sarcoidosis, the differential diagnosis includes reactivation of latent sarcoidosis with adalimumab as a trigger.

Cutaneous sarcoidosis

PURPOSE OF REVIEW

Cutaneous sarcoidosis occurs in up to 30% of patients with sarcoidosis and skin findings are often the initial presenting symptom. Cutaneous sarcoidosis is a rare skin disease and many aspects of the disease presentation and treatment are not well understood. This review will highlight developments in the epidemiology, clinical presentation, diagnosis and treatment of cutaneous sarcoidosis over the past several years.

RECENT FINDINGS

Epidemiological studies from several different populations reaffirm that cutaneous sarcoidosis is more common in women and is often the presenting symptom of systemic sarcoidosis. Recently, more cases are being reported in association with oncologic immune modulators, which will be of great interest as use of those agents increases. Also, ultrasound has shown promise for the imaging of cutaneous granulomas for disease assessment and measuring response to treatment. Finally, the treatment of cutaneous sarcoidosis remains difficult and is based largely on retrospective data with a paucity of large, prospective trials. There have been recently introduced and validated cutaneous scoring tools which show promise and may lead to more high-quality studies going forward.

SUMMARY

The recent developments in cutaneous sarcoidosis have identified many new pharmacologic and physical triggers of disease, but the evidence for effective treatment is still lacking. Further research is necessary to improve the care of patients with cutaneous sarcoidosis.
