Data also showed that these inhibitors, particularly Remicade (infliximab), may work slightly better for patients who have symptoms of sarcoidosis also outside the lungs (extrapulmonary sarcoidosis) than for those who have only lung involvement (pulmonary sarcoidosis). The study, “Role of anti-tumor necrosis factor-alpha agents in treatment of sarcoidosis: A meta-analysis,” was published in the European Journal of Internal Medicine.

Most people with sarcoidosis experience problems in the lungs, often manifesting as shortness of breath and persistent dry cough. Many do not need treatment, but if pharmacological treatment is recommended, it usually includes corticosteroids to help reduce inflammation. If corticosteroids are not enough or there are worries about side effects, other immunosuppressive treatments may sometimes be used. While they are not approved for sarcoidosis, TNF-alpha inhibitors are used off-label by about one in 10 sarcoidosis patients in the U.S. who do not respond well to other medications. TNF-alpha inhibitors work by blocking the activity of TNF-alpha, a molecule present in high amounts in inflamed tissues, where it helps prolong inflammation. By suppressing TNF-alpha, these treatments are expected to reduce inflammation. Efficacy data of anti-TNF-alpha treatments in hard-to-treat (refractory) sarcoidosis are “mixed and inconclusive,” the researchers wrote. Although [TNF-alpha inhibitors] are the last option in treatment for some patients, they appear to be a practical and advantageous treatment option Meta-analysis included a total of 398 sarcoidosis patients To know more, a team of researchers in Iran and the U.S. performed a meta-analysis, a type of analysis that combines data from a number of different studies from the literature. They performed a systematic review of published studies up to April 10, 2022, that reported the efficacy of TNF-alpha inhibitors in people with pulmonary and extrapulmonary sarcoidosis in clinical trials. Of the 22 studies assessed for eligibility, eight — involving a total of 398 sarcoidosis patients — were included in the meta-analysis. Most of these clinical trials were conducted in the U.S. Four tested Remicade, two used etanercept (sold as Enbrel, among others), one evaluated adalimumab (sold as Humira, with biosimilars also available), and one tested Simponi (golimumab) in combination with Stelara (ustekinumab). Patients’ mean age was 48.5 years, and their treatment period ranged from 14 weeks (3.5 months) to 45 weeks (about 10 months). All medications were given as an under-the-skin injection, with the exception of Remicade, which was administered directly into the bloodstream. Treatment success, defined as symptom reduction or no disease progression, was observed in 69.9% of people with pulmonary sarcoidosis. In those with extrapulmonary sarcoidosis, the rate was slightly better (74.5%). When looking at treatment success rates across various organ involvements, Remicade appeared to work best, both for pulmonary sarcoidosis (80%–100% success rate) and extrapulmonary sarcoidosis (93%–100% success rate). Etanercept was associated with a treatment success rate of 31% among pulmonary sarcoidosis patients and 66% for those with eye manifestations. In sarcoidosis-related skin lesions, adalimumab treatment reduced or stabilized symptoms in 60% of patients, while the Simponi-Stelara combo was associated with a success rate of 32%.

Future appropriately controlled clinical trials, “using a standardized definition for objective treatment success,” are needed to confirm these findings, the team concluded.
