RESUMEN
Inorganic antigens may contribute to paediatric sarcoidosis. Thirty-six patients matched with 36 healthy controls as well as a group of 21 sickle-cell disease (SCD) controls answered an environmental questionnaire. Patients' indirect exposure to inorganic particles, through coresidents' occupations, was higher than in healthy and SCD controls (median score: 2.5 (0.5-7) vs 0.5 (0-2), p=0.003 and 1 (0-2), p=0.012, respectively), especially for construction, exposures to metal dust, talc, abrasive reagents and scouring products. Wood or fossil energies heating were also linked to paediatric sarcoidosis. This study supports a link between mineral environmental exposure due to adult coresident occupations and paediatric sarcoidosis.

BACKGROUND: Sarcoidosis is a systemic disease characterized by the formation of immune granulomas in various organs, mainly the lungs and the lymphatic system. Exaggerated granulomatous reaction might be triggered in response to unidentified antigens in individuals with genetic susceptibility. The present study aimed to determine the genetic variants implicated in a familial case of sarcoidosis. METHODS: Sarcoidosis presentation and history, NOD2 profile, NF-κB and cytokine production in blood monocytes/macrophages were evaluated in individuals from a family with late appearance of sarcoidosis. RESULTS: In the present study, we report a case of familial sarcoidosis with typical thoracic sarcoidosis and carrying the NOD2 2722G > C variant. This variant is associated with the presence of three additional SNPs for the IL17RA, KALRN and EPHA2 genes, which discriminate patients expressing the disease from others. Despite a decrease in NF-κB activity, IL-8 and TNF-A mRNA levels were increased at baseline and in stimulated conditions. CONCLUSIONS: Combination of polymorphisms in the NOD2, IL17RA, EPHA2 and KALRN genes could play a significant role in the development of sarcoidosis by maintaining a chronic pro-inflammatory status in macrophages.

OBJECTIVES: Infliximab (IFX) appears to be effective in refractory sarcoidosis. However, data are lacking regarding its efficacy in severe sarcoidosis (i.e. with cardiac and/or neurological involvement). METHODS: Retrospective single-centre study including 16 unselected consecutive patients with biopsy proven, severe, and resistant sarcoidosis, who were treated by infliximab (3 or 5 mg /kg at 0, 2 and 6 weeks, then every 8 weeks) between 2005 and 2013. RESULTS: Following IFX therapy we observed an improvement in 92% of cases, with a marked decrease of the severity score [median score 6 (3-12) vs. 2 (1-8), p<0.0001] and trend toward steroid sparing effect [12.5 (0-40) vs. 8.5 mg/d (0-30), p=0.11] between baseline and the end of follow-up, respectively. Regarding the index organ response, we observed a remission of cardiac and central nervous system involvements in 4 out of 4 and 11 out 12 cases, respectively. Thirty-eight percent of patients experienced a relapse. After a median follow-up of 57 months (2 to 91), we observed 7 (44%) infectious complications, 1 paradoxical cutaneous granuloma and 1 leucoencephalopathy. Infectious complications were mostly observed in male [6/7 (86%), p=0.06], with a longer duration of steroids (108 vs. 39 months, p=0.11) and immunosuppressant use prior IFX (42 vs. 24 months, p=0.08) compared to their negative counterpart, respectively. CONCLUSIONS: IFX was efficient in severe and refractory sarcoidosis. Infectious complications were frequent and occurred mainly in male patients with longer duration of steroids and immunosuppressant use prior to IFX.

PURPOSE OF REVIEW: Heart involvement during sarcoidosis is a medical emergency. The review focuses on published data analysis of clinical management and therapy involving a multidisciplinary monitoring of cardiac sarcoidosis. RECENT FINDINGS: With the emergence of new modalities, especially MRI and FDG PET scan, cardiac sarcoidosis is most often suspected and confirmed even in atypical cases. Laboratory investigations may help to diagnose and survey. Cardiac sarcoidosis drastically changes functional and vital prognosis. Recent studies define earlier detrimental predictable criteria to underline how beneficial is the combination of immunosuppressive therapy and cardiac treatment to patients. There are no large prospective studies, but case reports and small series support an appropriate therapeutic approach, which includes corticosteroids and immunosuppressive agents. SUMMARY: Our review illustrates the importance of looking for cardiac sarcoidosis in all sarcoidosis patients and to propose more specific and sensitive investigations when suspected on clinical and/or electrical signs. It emphasizes the need for more adapted criteria and even more prognostic criteria to choose the best therapeutic option.

Sarcoidosis is characterized by extensive local inflammation (granuloma, cytokine secretion) associated with anergy (poor response to antigens in vitro and in vivo). We postulated that this paradoxical situation would correspond to a disequilibrium between effector and regulatory T lymphocytes (T reg cells). We show that CD4+CD25(bright)FoxP3+ cells accumulate at the periphery of sarcoid granulomas, in bronchoalveolar lavage fluid, and in peripheral blood of patients with active disease. These cells exhibited powerful antiproliferative activity, yet did not completely inhibit TNF-alpha production. Sarcoidosis is therefore associated with a global T reg cell subset amplification whose activity would be insufficient to control local inflammation. At the same time, peripheral T reg cells exert powerful antiproliferative activity that may account for the state of anergy. Altogether, these findings advance our conceptual understanding of immune regulation in a way that resolves the immune paradox of sarcoidosis and permit us to envisage a profound clinical impact of T reg cell manipulation on immunity.

BACKGROUND: Neuro-ophthalmologic manifestations are uncommon in sarcoidosis. We aim to assess the prognostic factors and outcome of neuro-ophthalmic sarcoidosis. METHODS: We conducted a multicenter retrospective study on patients with neuro-ophthalmic sarcoidosis. Response to therapy was based on visual acuity, visual field, and orbital MRI exam. Factors associated with remission and relapse were analyzed. RESULTS: Thirty-five patients [median (IQR) age of 37 years (26.5-53), 63% of women] were included. The diagnosis of sarcoidosis was concomitant of neuro-ophthalmologic symptoms in 63% of cases. Optic neuritis was the most common manifestation. All patients received corticosteroids and 34% had immunosuppressants. At 6 months, 61% improved, 30% were stable, and 9% worsened. Twenty percent of patients had severe visual deficiency at the end of follow-up. Nonresponders patients had significantly worse visual acuity at baseline (p = 0.01). Relapses were less frequent in patients with retro-bulbar optic neuropathy (p = 0.03). CONCLUSION: Prognosis of neuro-ophthalmic sarcoidosis is poor.

BACKGROUND AND OBJECTIVES: Spinal cord sarcoidosis is a rare manifestation of sarcoidosis with a consequent risk of neurologic sequelae for the patient. We investigated prognostic factors and efficacy of immunosuppressive treatments in a longitudinal cohort. METHODS: We retrospectively studied patients with spinal cord sarcoidosis followed between 1995 and 2021 in 7 centers in France. Patients with definite, probable, or possible spinal cord sarcoidosis according to the Neurosarcoidosis Consortium Consensus Group criteria and with spinal cord involvement confirmed by MRI were included. We analyzed relapse or progression rate with a Poisson model, initial Rankin score with a linear model, and change in the Rankin score during follow-up with a logistic model. RESULTS: A total of 97 patients were followed for a median of 7.8 years. Overall mean relapse or progression rate was 0.17 per person-year and decreased over time. At last visit, 46 (47.4%) patients had a loss of autonomy (Rankin score ≥2). The main prognostic factors significantly associated with relapse or progression rate were gadolinium enhancement (relative rate [95% CI] 0.61 [0.4, 0.95]) or meningeal involvement (relative rate [95% CI] 2.05 [1.31, 3.19]) on spinal cord MRI and cell count (relative rate [95% CI] per 1 log increase 1.16 [1.01, 1.33]) on CSF analysis. Relapse or progression rate was not significantly associated with initial Rankin score or Expanded Disability Status Scale. Tumor necrosis factor-α (TNF-α) antagonists significantly decreased relapse or progression rate compared with corticosteroids alone (relative rate [95% CI] 0.33 [0.11, 0.98]). Azathioprine was significantly less effective than methotrexate on relapse or progression rate (relative rate [95% CI] 2.83 [1.04, 7.75]) and change in Rankin score (mean difference [95% CI] 0.65 [0.23, 1.08]). DISCUSSION: Regarding the relapse or progression rate, meningeal localization of sarcoidosis was associated with a worse prognosis, TNF-α antagonists resulted in a significant decrease compared to corticosteroids alone, and methotrexate was more effective than azathioprine. CLASSIFICATION OF EVIDENCE: This study provides Class IV evidence that in individuals with spinal cord neurosarcoidosis, TNF-α antagonists were associated with decreased relapse or progression rate compared to corticosteroids alone, but other therapies showed no significant benefit.

The authors report on four patients aged over 50 with chronic myopathy suggestive of sporadic inclusion body myositis. They present progressive and selective weakness of the quadriceps femoris muscles. Asymmetrical and selective atrophy of the forearm muscles were noted in all, with more severe involvement of the flexors than the extensors. Biopsy revealed granulomatous myositis. Histological features of sporadic inclusion body myositis were lacking. Evidence for systemic sarcoidosis was found in one patient. Corticosteroid treatment was associated with a partial but significant improvement in two patients. Granulomatous myositis may mimic inclusion body myositis and may be steroid-responsive.

BACKGROUND: Prognostic factors are lacking in cardiac sarcoidosis (CS), and the effects of immunosuppressive treatments are unclear. OBJECTIVES: To identify prognostic factors and to assess the effects of immunosuppressive drugs on relapse risk in patients presenting with CS. METHODS: From a cohort of 157 patients with CS with a median follow-up of 7 years, we analysed all cardiac and extra-cardiac data and treatments, and assessed relapse-free and overall survival. RESULTS: The 10-year survival rate was 90% (95% CI, 84-96). Baseline factors associated with mortality were the presence of high degree atrioventricular block (HR, 5.56, 95% CI 1.7-18.2, p = 0.005), left ventricular ejection fraction below 40% (HR, 4.88, 95% CI 1.26-18.9, p = 0.022), hypertension (HR, 4.79, 95% CI 1.06-21.7, p = 0.042), abnormal pulmonary function test (HR, 3.27, 95% CI 1.07-10.0, p = 0.038), areas of late gadolinium enhancement on cardiac magnetic resonance (HR, 2.26, 95% CI 0.25-20.4, p = 0.003), and older age (HR per 10 years 1.69, 95% CI 1.13-2.52, p = 0.01). The 10-year relapse-free survival rate for cardiac relapses was 53% (95% CI, 44-63). Baseline factors that were independently associated with cardiac relapse were kidney involvement (HR, 3.35, 95% CI 1.39-8.07, p = 0.007), wall motion abnormalities (HR, 2.30, 95% CI 1.22-4.32, p = 0.010), and left heart failure (HR 2.23, 95% CI 1.12-4.45, p = 0.023). After adjustment for cardiac involvement severity, treatment with intravenous cyclophosphamide was associated with a lower risk of cardiac relapse (HR 0.16, 95% CI 0.033-0.78, p = 0.024). CONCLUSIONS: Our study identifies putative factors affecting morbidity and mortality in cardiac sarcoidosis patients. Intravenous cyclophosphamide is associated with lower relapse rates.

(1) Background: Pediatric sarcoidosis is a rare and mostly severe disease. Very few pediatric series with a prolonged follow-up are reported. We aimed to evaluate the evolution of pediatric sarcoidosis in adulthood. (2) Material and methods: Patients over 18-years-old with a pediatric-onset sarcoidosis (≤15-year-old) who completed at least a three-year follow-up in French expert centers were included. Clinical information at presentation and outcome in adulthood were studied. (3) Results: A total of 52 patients were included (34 prospectively in childhood and 18 retrospectively in adulthood), with a mean age of 12 (±2.7) at diagnosis. The median duration time of follow-up was 11.5 years (range 3-44.5). Relapses mostly occurred during treatment decrease (84.5%), others within the three years after treatment interruption (9.1%), and rarely when the disease was stable for more than three years (6.4%). Sarcoidosis was severe in 11 (21.2%) in adulthood. Patients received a high corticosteroid cumulative dose (median 17,900 mg) for a median duration of five years (range 0-32), resulting in mostly mild (18; 35.3%) and rarely severe (2; 3.8%) adverse events. (4) Conclusions: Pediatric-onset sarcoidosis needed a long-term treatment in almost half of the patients. Around one fifth of pediatric-onset sarcoidosis patients had severe sarcoidosis consequences in adulthood.
RESUMEN
OBJECTIVE: To describe the clinical presentation, distribution of lesions, treatment, and outcomes of osseous sarcoidosis. METHODS: A French retrospective multicenter study of patients with biopsy-proven sarcoidosis analyzed patients with 1) a biopsy-proven granuloma without caseous necrosis, and either 2) osseous clinical manifestations, or 3) abnormal osseous imaging. Sarcoidosis patients with osseous involvement (cases) were compared with 264 age- and sex-matched sarcoidosis patients with no osseous manifestations (controls). RESULTS: In the osseous sarcoidosis group (n=88), forty-two (48%) patients had osseous-related symptoms involving the axial (69%) and/or appendicular (58%) skeleton. On imaging, the most commonly affected bones were in the spine (52%), pelvis (42%), hands (22%) and femur (19%). Compared with controls, cases had higher rates of mediastinal (93% vs. 47%) and extra-thoracic lymph node involvement (66% vs. 21%), pulmonary (90% vs. 65%) and cutaneous involvement (44% vs. 23%) (all P<0.0001), and hypercalcemia (8.5% vs. 2%, P=0.014). Spleen/liver and gastrointestinal involvement were less frequent in the osseous sarcoidosis group (29% vs. 45%, and 1% vs. 17%, respectively, P<0.0001). Response rates to with glucocorticoids alone, glucocorticoids plus methotrexate or glucocorticoids plus hydroxychloroquine were 23/44 (52%), 9/13 (69%) and 4/6 (67%), respectively. CONCLUSION: In patients with osseous sarcoidosis the spine and pelvis were the most commonly affected bones. Compared with controls, cases with osseous sarcoidosis have higher rates of thoracic and extra-thoracic lymph node involvement, pulmonary and cutaneous involvement, and hypercalcemia. Most patients with osseous sarcoidosis had a good response to glucocorticoids in combination with methotrexate or hydroxychloroquine.

When involving some organ systems, sarcoidosis can affect functional outcome and/or constitute a life-threatening condition. Neurological expression is often overt and thus easily diagnosed. However, diagnosing heart involvement requires a thorough history taking and at least one systematic electrocardiogram. These lesions are serious and require a corticosteroid therapy, initiated in most cases at the daily dose of 1 mg/kg. This therapy should be combined with organ-specific treatments, always necessary though not sufficient.

OBJECTIVE: To describe the features of exceptional coexisting Takayasu arteritis (TA) and sarcoidosis, two conditions of unknown cause associated with a common immunologic pattern. METHODS: We report seven cases of concomitant sarcoidosis-Takayasu or Takayasu-like vasculitis, observed in two referral centers between 1995 and 2015. RESULTS: All patients were female. The mean age at sarcoidosis diagnosis and TA diagnosis was 36 and 37 years, respectively. Sarcoidosis occurred in 86% of cases before or together with TA. Sarcoidosis always had a classic expression except for one renal localization. Sarcoidosis was not severe and mostly non-treated (86%). In all cases of TA, supra-aortic arteries were involved; in only two TA cases a more diffuse inflammatory arterial involvement was noted. In one case, Takayasu arteritis occurred despite immunosuppressive therapy given for sarcoidosis. All patients received for TA a treatment with corticosteroids associated with methotrexate (four cases), infliximab (one case) or tocilizumab (one case). After a mean follow-up of 89 months, TA always improved and no death was observed. CONCLUSIONS: TA stands as pathology associated with sarcoidosis. TA occurred in three cases among 50. When sarcoidosis preceded TA, a recovery of sarcoidosis was achieved mostly without treatment. TA is a prognostic and therapeutic factor. Immunosuppressive treatment, including steroids, led to a good prognosis for TA as well as for sarcoidosis.

Background: Tumor necrosis factor (TNF) antagonists have been reported as an efficient third-line therapy for sarcoidosis but there is no data regarding patients who do not respond to this treatment. Objective: To report the characteristics, the outcome and the response to therapy of patients with sarcoidosis resistant to TNF antagonists. Methods: Patients from the French STAT (Sarcoidosis Treatment with Anti-TNF) registry who were classified as non-responders and who were followed-up for >1 year were included. The response to further therapies was classified as complete response, or partial response, and the others were classified as non-responders. Results: Among the 132 patients from the registry, 14 were considered as non-responders to anti-TNF. Nine patients (66% of women; mean age 48 years) were analyzed. The mean number of organs involved was 4.2. Seven patients were previously treated with more than 2 immunosuppressive treatments. The mean duration of the anti-TNF treatment was 9 months (range, 3-24). After a mean follow-up duration of 58 months (median, 35; range, 19-128) a complete response was observed in 2/9 cases, a partial response in 5/9 cases, and 2/9 cases were considered as non-responders. In all but one patient, the immunosuppressant that allowed the clinical response had previously been used. Furthermore, the dosage was not necessarily increased to gain efficacy. Non-responders were treated by corticosteroids only because of their comorbidities or noncompliance. Conclusion: In patients who do not respond to TNF antagonists, previously used immunosuppressants may be useful. Excluding a differential diagnosis, assessing compliance and testing for anti-drug antibodies should be systematic. (Sarcoidosis Vasc Diffuse Lung Dis 2018; 35: 371-375).
RESUMEN
Importance: Prognostic factors are lacking in neurosarcoidosis (NS), and the association of immunosuppressive treatments with outcomes are unclear. Objectives: To identify prognostic factors of and analyze the association of immunosuppressive treatment with relapse of NS. Design, Setting, and Participants: In this retrospective study, a cohort of 234 patients fulfilled the diagnostic criteria for NS in a tertiary referral center in Paris, France, from January 1, 1990, through December 31, 2015. The median follow-up was 8 years (range, 2 months to 23 years). Main Outcomes and Measures: All neurologic and extraneurologic data and treatments were analyzed. Functional outcomes measured by the absolute value and the variation from baseline of the Expanded Disability Status Scale (EDSS) score at 60 months after the diagnosis, overall survival, and relapse-free survival (RFS) were assessed. Analyses were stratified by the period of NS diagnosis (1990-1999 vs 2000-2015). Results: The 234 patients undergoing assessment included 117 women (50.0%) and 117 men (50.0%); median age was 42 years (interquartile range, 32-53 years). The probable 10-year survival rate was 89% (95% CI, 84%-94%). Older age (hazard ratio [HR] per 10 years, 1.64; 95% CI, 1.19-2.27; P = .003), peripheral nervous system involvement (HR, 6.75; 95% CI, 2.31-19.7; P < .001), and higher baseline EDSS score (HR per point, 1.21; 95% CI, 1.06-1.39; P = .005) were associated with mortality. The estimated 10-year RFS rate was 14% (95% CI, 9%-22%) for all relapses and 28% (95% CI, 20%-38%) for neurologic relapses. Encephalic involvement was associated with shorter neurologic RFS (HR, 2.35; 95% CI, 1.44-3.83; P < .001). A lower risk for relapse was associated with cyclophosphamide (HR, 0.26; 95% CI, 0.11-0.59; P = .001), methotrexate sodium (HR, 0.47; 95% CI, 0.25-0.87; P = .02), and infliximab (HR, 0.16; 95% CI, 0.02-1.24; P = .08) treatments. Follow-up was greater than 60 months in 160 patients (68.4%). An elevated baseline EDSS score (odds ratio [OR] per point, 1.92; 95% CI, 1.55-2.37; P < .001), tobacco use (OR, 3.64; 95% CI, 1.36-9.73; P = .01), encephalic symptoms (OR, 3.04; 95% CI, 1.11-8.38; P = .03), and less than 4 extraneurologic sarcoidosis localizations (OR, 3.06; 95% CI, 1.04-8.98; P = .04) were associated with an EDSS value of at least 2.5 at 60 months. Encephalic involvement (16 of 17 patients [94.1%]; P = .008) and peripheral nervous system involvement (5 of 17 patients [29.4%]; P = .03) were associated with worsening of the EDSS score at 60 months. Conclusions and Relevance: This study identifies putative factors affecting morbidity and mortality in patients with NS. Immunosuppressive therapies (ie, intravenous cyclophosphamide, methotrexate, and infliximab) in these patients may be associated with lower relapse rates.

BACKGROUND: Cardiac sarcoidosis (CS) is a severe localization, observed mostly in cardiology departments. Despite appropriate cardiological treatment, CS is a potentially life-threatening condition, and accounts for 13-85% of sarcoidosis-related deaths. AIMS: This retrospective study aimed to give an overview of CS in a non-cardiac unit, to analyse the effect of first-line immunosuppressive treatment on outcome and survival and to evaluate factors associated with relapses. METHODS: From 534 cases of sarcoidosis, we selected 59 patients with CS according to "2006 international criteria". We performed an in-depth analysis regarding symptoms, physical signs and cardiac investigation results. Patients were followed for a median period of 60 months. RESULTS: The median age at cardiac signs was 42 years. Echocardiography abnormalities, isotopic defects and abnormal magnetic resonance imaging findings were observed in 81%, 84% and 92% of patients, respectively. First-line treatment included steroids alone in 24 patients and steroids plus immunosuppressive therapy in 35 patients. Forty-seven (80%) patients recovered; 12 stabilized or worsened. The recovery rate was 75% in the steroids alone group versus 83% in the steroids plus immunosuppressive therapy group. Five (9%) patients died during follow-up, with two deaths attributed to CS. The overall 1- and 5-year survival rates were 98% and 92%, respectively. CONCLUSION: Our series of patients with CS who received steroids alone or combined with immunosuppressive therapy had a good prognosis, with an overall 5-year survival rate of 92%. The recovery rate was 85%, with no significant difference between patients treated with steroids alone or plus immunosuppressive therapy.
RESUMEN
Backgroung: This study investigated the efficacy and safety of TNF antagonists in sarcoid uveitis in unselected cases. Design: This is a multicentre study on patients with sarcoidosis who received TNF antagonists in pneumology and internal medicine departments in France. We present here the subgroup of patients with biopsy-proven sarcoid uveitis included in the nationwide registry STAT (Sarcoidosis treated with TNF AnTagonists). Results: Among the 132 patients included in this multicenter study, 18 patients with refractory uveitis were treated as a first-line TNF antagonist with infliximab (n=14), adalimumab (n=3) and certolizumab (n=1). Before anti-TNF initiation, the median duration of sarcoidosis was 42 months and 83% of the patients have been treated with at least one immunosuppressive drug. Six patients switched for a second-line TNF antagonist. After a mean time under treatment of 29 months, the treatment resulted in a significant decrease of the ophthalmic extrapulmonary Physician Organ Severity Tool (ePOST) (mean score: 4.2 vs. 2.6) scores and a steroid sparing effect (29.4±20.7 vs. 6.2±5.2 mg/d). Overall, the ophthalmic response, either complete or partial, was 67%. Nine patients (50%) presented adverse events, including severe infectious complications in 5 patients, which required anti-TNF treatment interruption in 6 cases (33%). Among the 7 responder patients who discontinued anti-TNF therapy, 71% relapsed. Finally, 12 patients (67%) could continue TNF antagonist treatment. Conclusions: TNF antagonists were efficient in 67% of biopsy-proven refractory sarcoid uveitis. Severe adverse events, mainly infectious complications, were frequent. The high frequency of relapses after anti-TNF-α discontinuation requires a close patient follow-up thereafter. (Sarcoidosis Vasc Diffuse Lung Dis 2017; 34: 74-80).
RESUMEN
Importance: Evidence for the long-term efficacy and safety of anti-tumor necrosis factor α agents (anti-TNF) in treating cutaneous sarcoidosis is lacking. Objective: To determine the efficacy and safety of anti-TNF in treating cutaneous sarcoidosis in a large observational study. Design, Setting, and Participants: STAT (Sarcoidosis Treated with Anti-TNF) is a French retrospective and prospective multicenter observational database that receives data from teaching hospitals and referral centers, as well as several pneumology, dermatology, and internal medicine departments. Included patients had histologically proven sarcoidosis and received anti-TNF between January 2004 and January 2016. We extracted data for patients with skin involvement at anti-TNF initiation. Main Outcomes and Measures: Response to treatment was evaluated for skin and visceral involvement using the ePOST (extra-pulmonary Physician Organ Severity Tool) severity score (from 0 [not affected] to 6 [very severe involvement]). Epidemiological and cutaneous features at baseline, efficacy, steroid-sparing, safety, and relapses were recorded. The overall cutaneous response rate (OCRR) was defined as complete (final cutaneous ePOST score of 0 or 1) or partial response (ePOST drop ≥2 points from baseline but >1 at last follow-up). Results: Among 140 patients in the STAT database, 46 had skin involvement. The most frequent lesions were lupus pernio (n = 21 [46%]) and nodules (n = 20 [43%]). The median cutaneous severity score was 5 and/or 6 at baseline. Twenty-one patients were treated for skin involvement and 25 patients for visceral involvement. Reasons for initiating anti-TNF were failure or adverse effects of previous therapy in 42 patients (93%). Most patients received infliximab (n = 40 [87%]), with systemic steroids in 28 cases (61%) and immunosuppressants in 32 cases (69.5%). The median (range) follow-up was 45 (3-103) months. Of the 46 patients with sarcoidosis and skin involvement who were treated with anti-TNF were included, median (range) age was 50 (14-78) years, and 33 patients (72%) were women. The OCRR was 24% after 3 months, 46% after 6 months, and 79% after 12 months. Steroid sparing was significant. Treatment was discontinued because of adverse events in 11 patients (24%), and 21 infectious events occurred in 14 patients (30%). Infections were more frequent in patients treated for visceral involvement than in those treated for skin involvement (n = 12 of 25 [48%] vs n = 2 of 21 [9.5%], respectively; P = .02). The relapse rate was 44% 18 months after discontinuation of treatment. Relapses during treatment occurred in 35% of cases, mostly during anti-TNF or concomitant treatment tapering. Conclusions and Relevance: Anti-TNF agents are effective but suspensive in cutaneous sarcoidosis. The risk of infectious events must be considered.
