Popis: Background:The rate of co-occurrence of Familial Mediterranean Fever (FMF) and axial spondyloarthritis (axSpA) in adults is reported ranging from 0.5% to 7.5%. The clinical implications of this co-occurrence in the course of FMF is still a research question.Objectives:To compare of demographic and clinical features of patients with FMF and FMF+axSpA.Methods:A total of 9630 FMF patients was detected according to the ICD-10 code (E85.0) of FMF in Hacettepe University Hospital database. 241 of these patients also had axSpA according to the ICD-10 code (M45). FMF diagnosis was confirmed by Tel-Hashomer criteria. AxSpA was diagnosis was confirmed by either presence of sacroiliitis on sacroiliac radiography according to the Modified New York Criteria (mNY) or presence of active sacroiliitis according to ASAS criteria on magnetic resonance imaging. 136 patients were confirmed according to these criterias as having FMF+axSpA. As a control group, 231 consequent FMF patients without axSpA recorded on the “FMF in Central Anatolia (FiCA) database” and followed up at our center were included in the analysis. Demographic and clinical features of those patients in both groups were compared. pResults:136 patients were included in FMF+axSpA group and 231 patients were included in FMF group. 114 (83.8%) patients in FMF+axSpA group had radiographic sacroiliitis according to mNY criteria; median cervical mSASSS was 0 (available for 49 patients, min-max, 0-36), median lumber mSASSS was 4 (available for 121 patients, min-max, 0-36), 33 (27%) patients had cervical or lumber syndesmophyte. Twenty-six (19.1%) of these patients had radiologically documented inflammatory hip disease 12 (8.8%) of these patients underwent total hip replacement. Female gender was more prevalent in FMF+axSpA group (53.7% vs 32.5%, pConclusion:The coexistence of spondyloarthritis in FMF patients appears to be associated with the increased prevalence of amyloidosis. The inflammatory burden of a second disease and the increased prevalence of the homozygous M694V mutation may explain this risk.Table 1.Comparison of demographic and clinical features of two groups.FMF+AxSpA(n=136, 37.1%)FMF(n=231, 62.9%)pFemale, n(%)73 (53.7)75 (32.5)Age at FMF symptom onset, years med (IQR)12 (5-20)10 (6-18)0.046Symptom duration, years, med (IQR)24 (18-32)20 (14-29)0.007Age at FMF diagnosis, years, med (IQR)24 (13-33)20 (11-30)0.10Duration after diagnosis, years, med (IQR)16 (10-22)13 (7-17)FMF signs and symptoms, n(%)-Fever128 (94.1)204 (88.3)0.067-Abdominal pain123 (90.4)217 (93.9)0.21-Pleuritis31 (22.8)87 (37.7)0.003-Pericarditis3 (2.2)2 (1.0)0.34-Arthritis64 (47.1)92 (39.8)0.17-Erysipelas24 (17.6)38 (16.5)0.77-Febrile myalgia9 (6.6)13 (5.6)0.70Inflammatory back pain, n(%)92 (67.6)26 (11.3)Inflammatory bowel disease, n(%)6 (4.4)4 (1.7)0.12FMF family history, n(%)-Any degree66 (48.5)137 (59.8)0.04-First degree48 (35.8)97 (42.0)0.24-Second degree25 (18.7)86 (37.2)Number of attacks at recent year, med (min-max)1 (0-12)1 (0-10)0.13Amyloidosis9 (6.6)4 (1.7)0.014M694V status (N=273)-Present (one or two allels)91 (80.5)120 (75.0)0.28-Two allels45 (39.8)43 (28.9)0.02Disclosure of Interests:None declared
