Popis: Background:Adult-onset Still’s disease (AOSD) is a rare systemic inflammatory disorder. In recent years biological disease modifying antirheumatic drugs (bDMARDs) are becoming increasingly important for its treatment.Objectives:To evaluate disease outcomes, treatment strategies and their long-term safety in a cohort of AOSD patients treated with bDMARDs.Methods:A single-center retrospective study of patients diagnosed with AOSD until 2019 was conducted. Patients were included if they: a) were 16 years old or older, b) met the Yamaguchi criteria and c) had received a bDMARDDemographics, clinical and laboratory parameters were collected at the time of diagnosis.Data regarding treatment lines included: the previous and concomitant conventional disease modifying antirheumatic drugs (cDMARDs), the type of initial bDMARD, switches, survival and corticosteroids discontinuation. Adverse events related to treatment and disease outcomes including death and amyloidosis were also recorded.Results:Sixteen patients with AOSD (Table 1) refractory to cDMARDs were administered biologics. The median duration of follow-up was 14 years (range 1-24). Consistent with recent literature1, two distinct disease patterns were recognized: the systemic form (SF) and the chronic articular form (CAF). In the SF the leading clinical symptoms were fever, pericarditis and pleuritis. In CAF the leading clinical symptom was persistent RA-like arthritis.Table 1.Some clinical and laboratory features of patients with FMF or MEFV mutations accompanied by demyelination diseaseCasesAge/SexDiseasesMEFV mutationsThe onset age/diagnostic age for FMFThe onset age for DD/MS/Presenting manifestations/MRI findingsTreatment for FMF /DD/MSCase 1(F1)17/FFMF+DDM694V homozygous3/515OB (-)Fusiform plaques in the cingulate gyrus; plaques in T4-6ColchicineIL-1 RAGlatiramer acetateCase 2(F1)46/FFMF+MSM694V homozygous8/928Optic nerve involvementOB(+)Plaques (+)ColchicineGlatiramer acetateCase 3(F1)17/FFMF+MSM694V heterozygous3/515Loss of the right eye, vertigoOB(+)PlaquesColchicinePulse steroidBeta-interferonTeriflunomideCase 4(F2)36/FMS+MEFV mutationM694V/R202Q-27Headache, blurred vision, optic nerve atrophyOB(+)Plaques (+)Glatiramer acetateCase 5(F2)16/FMS?+FMF+Cutaneous vasculitisM694V/R202Q16/1611Headache, blurred visionNo LP (denied by pt)Plaques-F: Female, F1: Family 1, F2: Family 2; DD: Demyelination disease;MS: Multiple sclerosis;MRI: Magnetic resonance imaging; OB:Oligoclonal band; LP: Lumbar punctionTable 1.Summary of patient characteristics at the time of diagnosisCharacteristicsResultsAge at the time of diagnosis median, (range) years32.5 (18-64)Sex (N)11 female, 5 maleFever14 (87.5%)Rash8 (50%)Lymphadenopathy2 (12.5%)Arthritis15 (93.75%)Pleuritis7 (43.7%)Pericarditis9 (56.25%)Hepatosplenomegaly2 (12.5%)Elevated liver enzymes2 (12.5%)Hyperferritinaemia4 (25%)Patients with the SF were treated with anakinra (n=4), tocilizumab (TCZ; n=3), canakinumab (n=1) and anti-TNFa (1 adalimumab, 1 etanercept) (n=2). Patients with the CAF received anti-TNFa (3 infliximab, 1 etanercept) (n=4) and TCZ (n=2). The median time from biologic initiation to corticosteroids discontinuation was 6.5 months, (range 2-32), (Table 2). 9 patients (56.25%) remained on treatment with the initial bDMARD, 4 patients (25%) received treatment with two and 3 patients (18.75%) with ≥ 3 bDMARDs. All patients with the CAF were on bDMARD at the end of follow-up, while 4/10 patients (40%) with the SF discontinued it. During follow-up only one serious adverse event was attributed to bDMARD (allergic reaction to infliximab infusion). There were no cases of amyloidosis or deathsConclusion:Dichotomous phenotype in AOSD can determine treatment strategy for initial biologic treatment. Inhibition of IL-1 and IL-6 was the preferred therapeutic option for systemic form while inhibition of TNF and IL-6 was the preferred option for the chronic articular form. All of the above bDMARDs have favorable long-term safety profile in patients with AOSD.References:[1]François Vercruysse et al.
