Summary

Long since it have been suggested that a subpopulation of patients with rheumatoid arthritis (RA), diagnosed with negative rheumatoid factor (RF) tests, represents a clinical entity quite distinct from that of seropositive rheumatoid arthritis. Th e aim of the study was to establish a scientific comparative analysis between RA seronegative and seropositive, regarding course and prognoses of the disease. Two hundred fi ft y patients with rheumatoid arthritis according to the (American College of Rheumatology) criteria were retrospectively studied by analysis the course and prognoses of disease. All examinees were between 25-60 years of age (Xb=49.9, SD=10.3) with disease duration between 1-27 years (Xbox=6.41, SD=6.47). Course of the disease with “remissions and exacerbations”, progressive continual course and bad prognoses, were more presented in seropositive group of patients. Partial remission was more common in seronegative patients but according to serostatus and gender has not shown statistically significant difference. Duration of the disease was a specific prognostic sign for both subsets [(r=0.32, p<0.01) seronegative, (r=0.22, p<0.05) seropositive], while age was only a specific prognostic sign for the seropositive subset [(r=0.01, p>0.05) seronegative, (r=0.18, p<0.05) seropositive]. Seropositive and seronegative RA distinguish in course and prognostic feature, but not enough to differentiate them in two different forms of the disease. Regarding the sero-status, differences within sex, with some exceptions, are not relevant.

Sažetak
Već odavno je sugerirano da subpopulacija bolesnika s reumatidnim artritisom (RA), diagnosticirana s negativnim testom za reumatoidni faktor (RF), predstavlja klinički entitet sasvim različit od populacije sa seropozitivnim reumatoidnim artritisom. Da bi se uspostavila znanstvena komparativna analiza između seronegativnog i seropozitivnog reumatoidnog artritisa (RA), u odnosu na tijek i prognozi bolesti, dvjesto pedeset bolesnika s reumatoidnim artritisom u skladu s kriterijima ACR (American College of Rheumatology), retrospektivno su ispitivani analizom tijeka i prognoze bolesti. Svi ispitanici su bili između 25-60 godina (Xb=49,9, SD=10,3) s trajanjem bolesti od 1-27 godina (Xb=6,41, SD=6,47). Tijek bolesti s “remisijama i egzacerbacijama”, kontinualno progresivni tijek i loša prognoza, bile su prisutnije u seropozitivnoj skupini bolesnika. Djelomična remisija je bila prisutnija u seronegativnoj skupini bolesnika, mada u odnosu na serostatus i spol nije pretstavljala statistički značajnu razliku. Dužina trajanja bolesti se pokazala kao specifični prognostički znak za obe skupine [(r=0,32, p<0,01) seronegativni, (r=0,22, p<0,05) seropozitivni], dok sepokazao specifični prognostički znak samo za seropozitivnu skupinu [(r=0,01, p>0,05) seronegativni, (r=0,18, p<0,05) seropozitivni]. Seropozitivni i seronegativni RA se razlikuju po pitanju karakteristika tijeka i prognoze, ali ne dovoljno da bi ih razlikovali kao dvije različite vrste iste bolesti. U odnosu na spol, osim izvjesnih izuzetaka, razlike nisu značajne.
