The value of assessing disease activity with indices devised for rheumatoid arthritis (RA) was investigated in 72 patients with seronegative PA. Thirty patients had a peripheral polyarthritis including the distal inter-phalangeal joints (DIPJs) and 15 a symmetrical arthritis sparing DIPJs (RA-like). Significant correlations (Spearman rank test) were seen between the clinical variables (pain score, grip strength, Ritchie articular index and a summated index of disease activity) in these two groups. Ten patients with a markedly asymmetrical arthritis showed a poor correlation between clinical variables. Although the objective indices \u2013 erythrocyte sedimentation rate (ESR) and C-reactive protein \u2013 correlated together in the first two groups, the ESR correlated solely with clinical indices, and then only in RA-like patients.<\/jats:p>\n                  <jats:p>These results cast some doubt on the value of assessment methods based on RA when evaluating subgroups of PA other than RA-like disease.<\/jats:p>","DOI":"10.1177\/014107688708000907","type":"journal-article","created":{"date-parts":[[2018,3,8]],"date-time":"2018-03-08T01:06:16Z","timestamp":1520471176000},"page":"556-558","source":"Crossref","is-referenced-by-count":22,"title":["Indices of Disease Activity in Psoriatic Arthritis"],"prefix":"10.1177","volume":"80","author":[{"given":"A O'N","family":"Daunt","sequence":"first","affiliation":[{"name":"Wessex Rheumatology Research Group, Southampton General Hospital, Salisbury General Infirmary, and Royal Hampshire County Hospital, Winchester"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N L","family":"Cox","sequence":"additional","affiliation":[{"name":"Wessex Rheumatology Research Group, Southampton General Hospital, Salisbury General Infirmary, and Royal Hampshire County Hospital, Winchester"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J C","family":"Robertson","sequence":"additional","affiliation":[{"name":"Wessex Rheumatology Research Group, Southampton General Hospital, Salisbury General Infirmary, and Royal Hampshire County Hospital, Winchester"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M I D","family":"Cawley","sequence":"additional","affiliation":[{"name":"Wessex Rheumatology Research Group, Southampton General Hospital, Salisbury General Infirmary, and Royal Hampshire County Hospital, Winchester"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1987,9,1]]},"reference":[{"key":"bibr1-014107688708000907","doi-asserted-by":"publisher","DOI":"10.1016\/0049-0172(73)90035-8"},{"key":"bibr2-014107688708000907","doi-asserted-by":"publisher","DOI":"10.1016\/S0049-0172(79)80001-3"},{"key":"bibr3-014107688708000907","first-page":"513","volume":"21","author":"Dowart B.B.","year":"1978","journal-title":"Ann Rheum Dis"},{"key":"bibr4-014107688708000907","doi-asserted-by":"publisher","DOI":"10.1136\/ard.39.3.279"},{"key":"bibr5-014107688708000907","doi-asserted-by":"publisher","DOI":"10.1007\/BF03342624"},{"key":"bibr6-014107688708000907","first-page":"393","volume":"37","author":"Ritchie D.M.","year":"1968","journal-title":"Q J Med"},{"key":"bibr7-014107688708000907","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/20.1.14"}],"container-title":["Journal of the Royal Society of Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/014107688708000907","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/014107688708000907","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T05:38:03Z","timestamp":1777527483000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/014107688708000907"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1987,9]]},"references-count":7,"journal-issue":{"issue":"9","published-print":{"date-parts":[[1987,9]]}},"alternative-id":["10.1177\/014107688708000907"],"URL":"https:\/\/doi.org\/10.1177\/014107688708000907","relation":{},"ISSN":["0141-0768","1758-1095"],"issn-type":[{"value":"0141-0768","type":"print"},{"value":"1758-1095","type":"electronic"}],"subject":[],"published":{"date-parts":[[1987,9]]}}}
