Abstract
Several studies reported that Familial Mediterranean Fever (FMF) diagnosis may be missed or delayed even in countries with a high FMF prevalence. Our aim was to study on a large cohort of European FMF patients the frequency and associated factors of diagnosis delay. Clinical data were extracted from the Juvenile Inflammatory Rheumatism (JIR)-cohort. All FMF patients fulfilled Livneh Criteria and had been sequenced for MEFV exon 10. FMF-diagnostic delay (d-FMF) was defined as the duration between the onset of the symptoms and the diagnosis of more than 10 years. 960 FMF patients were enrolled: delayed diagnosis (d-FMF) was noted in 200 patients (20%). d-FMF patients were significantly older compared to non d-FMF with a median age of 46.4 years old vs. 15.5 (p < 0.0001). Women displayed more d-FMF compared to men (56 vs. 47%, p = 0.03). Clinical presentation during attacks was not statistically significant except for erysipelas-like erythema, which was higher among d-FMF patients (33 vs. 22%, p = 0.0003). The presence of one or two pathogenic MEFV mutation was not different between patients. Compared to other FMF, d-FMF patients displayed significantly more AA amyloidosis (10 vs. 2.6%, p < 0.0001) and received more biotherapy (18 vs. 3.8%, p < 0.0001). Twenty percent of FMF patients had a diagnostic delay >10 years, including more women. The differential diagnosis of abdominal attacks with menstrual pain may be an explanation, and erysipelas-like erythema may not be recognized as FMF by all practitioners.
期刊介绍:
RHEUMATOLOGY INTERNATIONAL is an independent journal reflecting world-wide progress in the research, diagnosis and treatment of the various rheumatic diseases. It is designed to serve researchers and clinicians in the field of rheumatology.
RHEUMATOLOGY INTERNATIONAL will cover all modern trends in clinical research as well as in the management of rheumatic diseases. Special emphasis will be given to public health issues related to rheumatic diseases, applying rheumatology research to clinical practice, epidemiology of rheumatic diseases, diagnostic tests for rheumatic diseases, patient reported outcomes (PROs) in rheumatology and evidence on education of rheumatology. Contributions to these topics will appear in the form of original publications, short communications, editorials, and reviews. "Letters to the editor" will be welcome as an enhancement to discussion. Basic science research, including in vitro or animal studies, is discouraged to submit, as we will only review studies on humans with an epidemological or clinical perspective. Case reports without a proper review of the literatura (Case-based Reviews) will not be published. Every effort will be made to ensure speed of publication while maintaining a high standard of contents and production.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
