Background: The aim of this study was to assess the serum chitotriosidase (ChT) and neopterin levels in patients with ankylosing spondylitis (AS) and to evaluate whether serum ChT and neopterin levels are related to disease activity. Methods: A total of 86 patients with AS were included in the study. Patients were divided into two groups based on Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores: The active AS patients group included 40 patients who had a BASDAI score ⩾4. The inactive AS patients group included 46 patients who had a BASDAI score <4. We compared the serum level of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), ChT and neopterin between the two groups. Results: Active AS patients had significantly higher ESR, CRP, serum ChT and neopterin levels compared with the inactive AS patients group ( p < 0.05). Positive correlations were found between serum ChT levels and ESR ( r = 0.87, p = 0.005), and CRP levels ( r = 0.86, p = 0.006). Also, there was a positive significant correlation between serum ChT levels and BASDAI scores ( r = 0.67, p = 0.03). No correlation was found between serum neopterin levels and the BASDAI scores, ESR, and CRP levels ( p > 0.05). Higher disease activity (BASDAI score ⩾4) was found to be associated with ChT ( p = 0.012) in the multiple logistic regression analysis. Conclusion: The present study emphasized that serum ChT levels can be useful in the determination of the disease activity of AS patients.

The C-reactive protein to prealbumin ratio (CPR) and fibrinogen to prealbumin ratio (FPR) in serum are two emerging biomarkers. The purpose of this study is to explore the relationship between these two markers and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Ankylosing Spondylitis Disease Activity Scores (ASDAS). A total of 163 patients with AS and 120 healthy examinees were included in this study. The t-test and Mann-Whitney U ranking test were used to analyze the differences between groups. The spearman-test was used to analyze the correlation between erythrocyte sedimentation rate (ESR), c-reactive protein (CRP), fibrinogen (Fib), prealbumin (PAlb), CPR, FPR, and AS disease activity in the test group. We generated the receiver operating characteristic curves (ROC) of CPR and FPR and determined the discriminating ability by calculating the area under the curve (AUC). Compared with the healthy group, ESR ( p < 0.001), CRP ( p < 0.001), Fib ( p < 0.001), CPR ( p < 0.001), and FPR ( p < 0.001) of AS patients were significantly increased, while PAlb was significantly reduced. CPR and FPR were more correlated to ASDAS-CRP. CPR was positively correlated with CRP, ESR, BASDAI, and ASDAS-CRP in AS patients ( r = 0.959, p < 0.001, r = 0.717, p < 0.001, r = 0.704, p < 0.001, r = 0.763, p < 0.001). FPR was positively correlated with CRP, ESR BASDAI, and ASDAS-CRP in AS patients ( r = 0.779, p < 0.001, r = 0709, p < 0.001, r = 0.551, p < 0.001, r = 0.763, p < 0.001). ROC showed that the AUC levels of CPR and FPR were high (AUC = 0.952 and AUC = 0.893). CPR and FPR are two promising new biological indicators for assessing disease activity in AS patients.

Background. Ankylosing spondylitis (AS) is a chronic, progressive inflammatory rheumatic disease that leads to structural damage, functional impairment, and decrease in the quality of life. Red cell distribution width (RDW) is a part of the complete blood count (CBC) and estimates erythrocyte variability. Objective. To analyse RDW in patients with AS and to evaluate the relationships with acute phase reactants (APRs) and disease activity index. Patients and Methods. A total of 100 patients with AS (78 males and 22 females) were diagnosed according to the modified New York classification criteria for AS and 146 (99 males: 47 females) healthy individuals matched in age and sex as controls enrolled in the study. Demographic data, disease activity scores using Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), medical history, C-reactive protein (CRP), erythrocytes sedimentation rate (ESR), and complete blood count (CBC) were measured. Results. The mean age for patients and controls was 38.0 ± 9.0 and 35.8 ± 9.0 years, respectively (p=0.057). RDW was significantly higher in patients with AS compared with controls (14.133 ± 1.613 versus 12.299 ± 1.031, p < 0.001). There was a direct correlation of RDW with both ESR and CRP (P < 0.001); RDW had r=0.38 for C-reactive protein (CRP) and r=0.413 for ESR. Also BASDAI was directly correlated with RDW (r=0.326 p<0.001). RDW was a valid measure to differentiate between patients with AS and controls (AUC=0,84, p<0.001) and at optimum cut-off value>13% has highest accuracy (78.9%) with very good sensitivity test (81%) and NPV (85.6%) as well as good specificity (77.4%) and PPV (71.1%). Conclusion. RDW was higher in AS patients compared with controls and was directly correlated with ESR, CRP, and BASDAI. RDW was a valid simple measure with good accuracy to differentiate between patients with AS and controls.

The Impact

Background:Spondyloarthritis is a group of chronic inflammatory diseases involving axial and peripheral joints. It mainly affects young patients typically of working age. Therefore, its impact on work outcomes may be considerable particularly in military patients.Objectives:The aim of this study was to evaluate the impact of spondyloarthritis on work ability and productivity in military patients, and to assess relationship between work productivity loss and disease activity.Methods:Thirty Three patients diagnosed with spondyloarthritis in the militay hospital of Tunis were included in the study. Age, gender and C-reactive protein were recorded. Data related to duration of the disease, Ankylosing Spondylitis Disease Activity Score (ASDAS) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were also recorded. Employed patients completed Work Productivity and Activity Impairment (WPAI) questionnaire witch assesses four subscales: presenteism, absenteism, overall work impairemend and daily activity impairement in the 7 past days.Results:Among the thirty three patients, 63 % were men and 37% were women. The average age was 43,7 ± 13,5. The average duration of disease was 8,5 ± 7,75 years. Mean C-Reactive protein was 27,5 ± 39,3. Mean ASDAS and BASDAI were 3,12 ± 1,39 and 4,26 ± 1,78 respectively. 22 patients (66%) had an active disease and 11 (33%)were in remission. 48,4% of patients were using NSAIDs, 48,4% were under DMARDs and 42% were under biologics (12 patients using TNF-alpha blockers and 2 patients were given IL-17 inhibitors). Among this patients, 27 were employed. Three patients (11%) had a total work disability and were retired from work and two have been outplaced.Employed patients worked an average of 35,6 ± 10,3 hours per week and missed an average of 3,48 ± 6,49 hours per week. The mean rates of absenteeism, presenteeism and work productivity loss were 8,8 ± 16,9 %, 48,4 ± 19,9 % and 48,6 ± 19,7 %.There was a statistically significant correlation between BASDAI and work missed hours (p<0,05, r=0,48), absenteeism (p<0,05, r=0,48), presenteeism (p<0,01, r=0,669), work impairement (p<0,01, r=0,669), activity impairement (p<0,05, r=0,475) and work productivity loss (p<0,05, r=0,475), as well as between ASDAS CRP and presenteeism (p<0,05, r= 0,593), work impairement (p<0,05, r=0,593), activity impairement(p<0,05, r=0,460) and work productivity loss (p<0,05, r=0,460). No relation was found between WPAI indexes and C-reactive protein.Conclusion:This study demonstrates that spondyloarthritis has a major impact on military patients’ work productivity with a significant correlation between WAPI indexes and disease activity scores (ASDAS CRP and BASDAI). No relation was found with C-reactive protein.Disclosure of Interests:None declared.

Background:Axial spondyloarthritis (ax-SpA) is a chronic rheumatic disease that mainly affects men. However, the female form of ax-SpA remains insufficiently studied.Objectives:The aim of this study was to determine the clinical characteristics, the disease activity and the functional impact of female ax-SpA in comparison with male ax-SpA.Methods:This is a retrospective study including patients diagnosed with ax-SpA fulfilling the criteria of the Assessment of SpondyloArthritis international Society (ASAS) 2009.Clinical parameters, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Bath ankylosing spondylitis disease activity index (BASDAI) and Bath ankylosing spondylitis functional index (BASFI) were compared between groups of female and male ax-SpA.Results:Two hundred ax-SpA patients were included with 31% of female (n=62) and a mean age of 43,3 ± 11,2 years.The mean age at onset of symptoms was 31,8 ± 8,9 years for women and 25,3 ± 9,1 years for men (p <0,0001). The mean age at diagnosis was 36,4 ± 9,6 years for women and 31,7 ± 10,4 years for men (p = 0,003). Ax-SpA with juvenile onset was noted in 1,7% of women and 12,1% of men (p = 0,02). Male ax-SpA were significantly more smokers (46.8% vs 5.4%; p <0.001). The mean duration of morning stiffness was 11,3 ± 9,2 minutes for women versus 21,6 ± 19,3 minutes for men (p = 0,005).The mean ESR was 42,4 ± 29,8 mm for women and 28,3 ± 23,4 mm for men (p = 0,001). Radiographic sacroiliitis was present in 69,3% of women versus 84,7% of men (p = 0,01). The use of anti-TNF alpha was less frequent in women (29% vs 48,5%; p = 0,01).Our study didn’t found a statistically significant difference in peripheral manifestations, extraarticular manifestations, CRP, BASDAI and BASFI between the two groups.Conclusion:Female ax-SpA seems to have a better prognosis than male with older age in disease onset, less inflammation, less radiographic sacroiliitis and less use of biological treatments.References:[1]Rusman T, et al.

Cilj: Svrha rada bila je utvrditi i usporediti učinkovitost te preživljenje TNF-α (engl. tumor necrosis factor-α) inhibitora (adalimumab, golimumab, infliksimab) tijekom trogodišnjeg praćenja u liječenju ankilozantnog spondilitisa. Materijali i metode: Ovim retrospektivnim istraživanjem obuhvaćena je skupina od 29 ispitanika koji su primili prvi biološki lijek na Odjelu reumatologije i kliničke imunologije Kliničkog bolničkog centra Rijeka. Započeli su s biološkim lijekom u razdoblju od siječnja 2009. do lipnja 2015. godine i bili praćeni tri godine nakon početka terapije. Parametri kojima se pratila aktivnost bolesti bili su BASDAI (engl. Bath Ankylosing Spondylitis Disease Activity Index), BASFI (engl. Bath Ankylosing Spondylitis Functional Index), CRP (engl. C reactive protein) i VAS (engl. Visual Analogue Scale), a mjereni su prije početka terapije te nakon 3 i 36 mjeseci od njenog uvođenja. Rezultati: Od ukupno 29 ispitanika, 11 ih je bilo na adalimumabu, 10 na golimumabu, a 8 na infliksimabu. Analizirajući parametre uključene u ovo istraživanje (BASDAI, BASFI, CRP, VAS), ni u jednom promatranom periodu nije zabilježena statistički značajna razlika između ispitanika s obzirom na primijenjeni TNF-α inhibitor (svi p &gt; 0,05). Ukupno trogodišnje preživljenje TNF-α inhibitora iznosilo je 75,8 %. Kod ispitanika liječenih adalimumabom trogodišnje preživljenje iznosilo je 72,8 %, za golimumab 80 % te infliksimab 75 % (svi p &gt; 0,05). Zaključci: Uspoređujući ispitanike liječene adalimumabom, golimumabom i infliksimabom u prvoj liniji biološke terapije, naše istraživanje na malom broju ispitanika pokazalo je kako nema značajne razlike u njihovoj učinkovitosti i preživljenju.
