Abstract

Beckground: Despite the recent advances in the field of autoinflammatory diseases, most patients with recurrent fever episodes do not have any defined diagnosis. The present study aims at describing a cohort of patients suffering from apparently unexplained recurrent fever, in whom non-radiographic axial spondylarthritis (SpA) represented the unique diagnosis identified after a complete clinical and radiologic assessment.

Materials and methods: Patients' data were obtained from the international registry on Undifferentiated Systemic AutoInflammatory Diseases (USAIDs) developed by the AutoInflammatory Disease Alliance (AIDA) network.

Results: A total of 54 patients with recurrent fever episodes were also affected by non-radiographic axial SpA according to the international classification criteria. SpA was diagnosed after the start of fever episodes in all cases; the mean age at the diagnosis of axial SpA was 39.9 ± 14.8 years with a diagnostic delay of 9.3 years. The highest body temperature reached during flares was 42°C, with a mean temperature of 38.8 ± 1.1°C. The most frequent manifestations associated to fever were: arthralgia in 33 (61.1%) cases, myalgia in 24 (44.4%) cases, arthritis in 22 (40.7%) cases, headache in 15 (27.8%) cases, diarrhea in 14 (25.9%) cases, abdominal pain in 13 (24.1%) cases, and skin rash in 12 (22.1%) cases. Twenty-four (44.4%) patients have taken daily or on-demand non-steroidal anti-inflammatory drugs (NSAIDs) and 31 (57.4%) patients have been treated with daily or on demand oral glucocorticoids. Colchicine was used in 28 (51.8%) patients, while other conventional disease modifying anti-rheumatic drugs (cDMARDs) were employed in 28 (51.8%) patients. Forty (74.1%) patients underwent anti-tumor necrosis factor (TNF) agents and 11 (20.4%) were treated with interleukin (IL)-1 inhibitors. The response to TNF inhibitors on recurrent fever episodes appeared more effective than that observed with anti-IL-1 agents; colchicine and other cDMARDs were more useful when combined with biotechnological agents.

Conclusion: Signs and symptoms referring to axial SpA should be inquired in patients with apparently unexplained recurrent fever episodes. The specific treatment for axial SpA may lead to a remarkable improvement in the severity and/or frequency of fever episodes in patients with unexplained fevers and concomitant axial SpA.

Response to different treatments performed by patients included in the study; monotherapy and combination treatment with conventional or biotechnological disease modifying anti-rheumatic drugs (cDMARDs and bDMARDs, respectively) or colchicine were pointed out. The figure specifically describes treatment with colchicine (A), cDMARDs (B), anti-tumor necrosis factor (TNF) (C), and anti-interleukin (IL)-1 (D).
Figure 3
Figure 3
Bar charts describe the frequency of the main clinical manifestations observed during inflammatory attacks at the start and at the last assessment while on treatment with anti-tumor necrosis factor (TNF) agents (A) and interleukin (IL)-1 inhibitors (B). Skin manifestations observed among patients treated with TNF inhibitors consisted of urticarial skin rash in 2 patients, pustular rash in one patient, erythematous skin rash in one patient; the latter one persisted at the last assessment. Skin manifestations observed among patients treated with IL-1 inhibitors consisted of erythematous skin rash in one patient and maculo-papular skin rash in a second patient. None of them resolved during IL-1 inhibition.
