Background few studies reported the incidence of rheumatic disease in Italy using the most recent classification criteria.
Objectives The aim of the CAMPO-RE study was to assess the new incidence cases of Rheumatoid Arthritis (RA), Psoriatic Arthritis (PsA) and Polymyalgia Rheumatic (PMR) attending a primary rheumatologic outpatient's clinic of new institution, integrated in the community of Campobasso, a small town in the centre of Italy.
Methods Campobasso has a population of 49,501 inhabitants (1st January 2016) and Public Health is managed from a single health authority in the entire area. In Italy, all citizens are registered with a National Health System of General Practitioner Physicians (GPP). Between 1st June 2014 to 31st May 2016 all consecutive adult patients, sent by GPP of the municipality of Campobasso with any diagnosis of musculoskeletal symptoms/signs complains were evaluated in a single rheumatology outpatient clinic of our Academic Unit, that represent the first and unique reference for the GPP about rheumatic diseases in the territory. Subjects were classified using the EULAR criteria for RA, the CASPAR criteria for PsA and the 2012 ACR classification criteria for PMR. New incident cases were calculated using the number of cases as the numerator and population based on 1st January census of the municipality of Campobasso as the denominator.
Results 1003 adult patients, sent by GPP with articular or musculoskeletal complains were visited in our clinic. Of these, 409 patients inhabitants of the municipality of Campobasso were evaluated for the study. During the 2-years study period we diagnosed 18, 19 and 12 new cases of RA, PsA and PMR respectively, with a new incident cases rate of 18.18, 19.19 and 12.12/100,000/year on the whole population of Campobasso municipality. Age-related incident cases were also calculated (table 1).
Conclusions The results of our study could contribute to better define the new incident cases of these rheumatic disease classified with the new classification criteria. The incidences of RA, PsA and PMR seem to be similar to those reported in previous study1–3.
