Non-typhoidal (NTS) rarely causes bacteremia and subsequent focal infections as an extraintestinal complication, even in immunocompetent adults. A 25-year-old man was hospitalized for several days with difficulty moving due to fever, acute buttock pain, and shivering. He had no recent or current respiratory symptoms and no clear gastrointestinal symptoms. Physical examination revealed mild redness around the left buttock and difficulty raising the left lower extremity due to pain, in addition to which blood tests showed high levels of inflammatory markers. His clinical course and laboratory findings suggested sepsis, and magnetic resonance imaging revealed a high-intensity area in the left piriformis muscle on diffusion-weighted imaging; therefore, acute piriformis pyomyositis was strongly suggested. Cephazolin was started upon hospitalization; however, blood and stool cultures proved positive for NTS, and the antibiotics were changed to ceftriaxone. Follow-up MRI showed a signal in the left piriformis muscle and newly developed left pyogenic sacroiliitis. On the 25th hospital day, a colonoscopy was performed to identify the portal of entry for bacteremia, which revealed a longitudinal ulcer in the sigmoid colon in the healing process. His buttock pain gradually improved, and the antibiotics were switched to oral levofloxacin, which enabled him to continue treatment in an outpatient setting. Finally, the patient completed seven weeks of antimicrobial therapy and returned to daily life without leaving any residual disability. Invasive NTS infection due to bacteremia is rare among immunocompetent adults. Piriformis pyomyositis and subsequent pyogenic sacroiliitis should be added to the differential diagnosis of acute febrile buttock pain. In the case of NTS bacteremia, the entry site must be identified for source control. Additionally, the background of the host, especially in such an immunocompetent case, needs to be clarified; therefore, the patient should be closely examined.

INTRODUCTION
Brucellosis is a zoonotic illness caused by Brucella bacteria, primarily transmitted through contaminated dairy products or direct contact with infected animals. Brucellosis is highly prevalent in Iran, with Brucella melitensis biovar 1 being the primary causative agent. Musculoskeletal symptoms, including spondylitis, sacroiliitis, and peripheral arthritis, are common in brucellosis patients, but avascular necrosis of the hip joint is extremely rare.
CASE PRESENTATION
This case report presents a middle-aged woman from Iran with untreated brucellosis infection, who developed rapidly progressing avascular necrosis affecting both hip joints. The patient's social history did not indicate any use of tobacco or alcohol. Furthermore, there was no indication of any traumatic events affecting the patient's hip joints. The patient's family history did not reveal any rheumatologic disorders, and the patient had not been diagnosed with or reported using immune suppressant medications. Laboratory results confirmed that the patient was not diagnosed with sickle cell anemia. The patient had been intolerant to the prescribed medications, Rifampin and Doxycycline. Initially, she presented with severe bilateral hip pain, anorexia, vomiting, periodic chills and fever, myalgia, and night sweats. Pelvis X-ray confirmed bilateral hip avascular necrosis, and total hip arthroplasty was scheduled but subsequently canceled due to persistent brucellosis infection. Physical examination revealed limited hip motion, pain, and inability to bear weight. Laboratory tests indicated leukocytosis, elevated levels of CRP, and high titers on Wright and 2ME tests. Intravenous Ciprofloxacin was initiated, and further investigations were scheduled.
DISCUSSION
Osteoarticular complications are common in individuals with brucellosis. The sacroiliac joints are affected in 80 % of cases, while the spinal joints are affected in 50 %. Brucella-induced arthritis can be found in over 50 % of patients, with the lower limb joints being the most commonly affected. Failure to diagnose and treat hip arthritis caused by brucellosis promptly can lead to severe complications, including dislocation and avascular necrosis of the femoral head. Avascular necrosis is a condition where bone tissue dies due to compromised blood supply. It often remains asymptomatic initially and is usually found incidentally during radiographic imaging. Osteonecrosis of the femoral head can manifest as Legg-Calve-Perthes disease or as a complication of other medical conditions. Various factors can contribute to avascular necrosis, including hip dislocation or fracture, prolonged use of certain medications, excessive alcohol consumption, and certain medical conditions. Magnetic resonance imaging is considered the standard method for diagnosing avascular necrosis. Delay in diagnosing and treating brucellosis can result in permanent bone complications.
CONCLUSION
Brucellosis, a disease prevalent in endemic regions, should be considered as a cause of severe hip pain and other vague symptoms. Timely diagnosis and management are important, especially for high-risk patients with other health conditions and poor drug compliance, to prevent complications such as avascular necrosis.

VEXAS syndrome is a recently described autoinflammatory syndrome caused by the somatic acquisition of mutations in myeloid precursors and is frequently associated with hematologic malignancies, chiefly myelodysplastic syndromes. Disease presentation can mimic several rheumatologic disorders, delaying the diagnosis. We describe a case of atypical presentation resembling late-onset axial spondylarthritis, later progressing to a systemic inflammatory syndrome with chondritis, cutaneous vasculitis, and transfusion-dependent anemia, requiring high doses of steroids. Ruxolitinib was used as the first steroid-sparing strategy without response. However, azacitidine showed activity in controlling both inflammation and the mutant clone. This case raises the question of whether azacitidine's anti-inflammatory effects are dependent on or independent of clonal control. We discuss the potential relevance of molecular remission in VEXAS syndrome and highlight the importance of a multidisciplinary team for the care of such complex patients.

OBJECTIVES
This study aimed to assess the predictive factors of functional impairment in spondyloarthritis (SpA) patients assessed with bath ankylosing spondylitis functional index (BASFI) and Lequesne Index (LI).
METHODS
This retrospective study was conducted at the Rheumatology Department of Mohamed Kassab Institute of Orthopedics, Manubah, Tunisia, and collected data from 2008 to 2019 over a period of 4 months (August to November 2019). Socio-demographic and disease-related data of SpA patients were collected. Disease activity was assessed using the bath ankylosing spondylitis-global score (BASG-s) and the bath ankylosing spondylitis disease activity index (BASDAI). The spinal mobility was evaluated by the bath ankylosing spondylitis metrology index (BASMI). Structural progression was evaluated with the bath ankylosing spondylitis radiologic index (BASRI) and modified stoke ankylosing spondylitis spine score (mSASSS). A multivariate analysis was done to search for predictive factors associated with BASFI and LI.
RESULTS
A total of 263 patients were included. The mean age was 38.9 ± 12.7 years and the gender ratio was 2.7. The mean age of onset of SpA was 27.6 ± 10.8 years and disease duration was 11.3 ± 9.5 years. Occupation was significantly associated with BASFI and LI scores. A significant functional impact was notably correlated with a long duration of the disease. The two scores were correlated with a limitation of spinal mobility (BASMI), a greater disease activity (BASDAI and erythrocyte sedimentation rate) and a greater impact of the disease on health status (BASG-s). Significant functional impairment was also correlated with structural impairment (mSASSS, BASRI and sacroiliitis grade). The variables independently related to BASFI were the mSASSS score and the BASDAI. The variables independently related to LI were profession (unemployed subjects had higher scores), the mSASSS score and the BASMI.
CONCLUSION
Occupation, disease activity, mobility and structural progression predicted functional impairment in Tunisian SpA patients.

Axial spondyloarthropathy(AS) is a chronic inflammatory disease primarily affecting the axial skeleton, often characterized by sacroiliitis. While pulmonary embolism (PE), a potentially lethal condition, has been linked to several autoimmune diseases, limited data exist regarding PE risk among patients with AS. This retrospective cohort study utilized the Clalit Healthcare Services (CHS) database, including 5825 patients with AS and 28,356 matched controls. Follow-up began at the date of first AS diagnosis for patients and at the matched patient's diagnosis date for controls and continued until PE diagnosis, death, or study end date. Prevalence of PE before AS diagnosis in patients compared to controls was 0.4% vs. 0.2% ( < 0.01). The incidence rate of PE was 11.6 per 10,000 person-years for patients with AS and 6.8 per 10,000 person-years for controls. The adjusted hazard ratio (HR) for PE in patients with AS was 1.70 ( < 0.001). Subgroup analysis demonstrated excess risk for PE in patients with AS regardless of gender and age, with variations among AS treatment categories. Our findings highlight a significant association between AS and PE, indicating an increased risk in patients with AS independent of age and sex and suggests a subclinical level of inflammation. Preliminary results suggest a protective role of immunosuppressing drugs. Further research into the impact of treatment strategies should be conducted and could inform clinical management and reduce the life-threatening risk of PE in Patients with AS.

OBJECTIVE
Familial Mediterranean fever is the most common monogenic autoinflammatory disease. This study aimed to evaluate the relationship between sacroiliitis observed in familial Mediterranean fever and hematological inflammatory markers.
METHODS
In this study, 168 familial Mediterranean fever patients were examined. A total of 61 familial Mediterranean fever patients who had sacroiliac magnetic resonance imaging due to waist and hip pain were included in the study. According to the magnetic resonance imaging findings, patients were divided into two groups: with and without sacroiliitis. The relationship between hematological inflammatory markers and sacroiliitis was investigated.
RESULTS
The frequency of sacroiliitis was found to be 13.6% in all familial Mediterranean fever patients and 37.8% in patients with low back pain who underwent sacroiliac magnetic resonance imaging. Neutrophil count, neutrophil/lymphocyte ratio, monocyte/lymphocyte ratio, and systemic immune-inflammatory index were significantly higher in the sacroiliitis group than in the other group, and this difference was found to be statistically significant (p<0.05). As a result of the receiver operating characteristic analysis, it was observed that neutrophil/lymphocyte ratio, monocyte/lymphocyte ratio, and systemic immune-inflammatory index were very sensitive parameters in determining sacroiliitis in patients with familial Mediterranean fever.
CONCLUSION
It was observed that the frequency of sacroiliitis was increased in familial Mediterranean fever patients. It is predicted that hematological inflammatory markers such as neutrophil/lymphocyte ratio, monocyte/lymphocyte ratio, and systemic immune-inflammatory index can be used in the diagnosis of sacroiliitis.

OBJECTIVE
In the absence of axial psoriatic arthritis (axPsA)-specific tools, the BASDAI and Ankylosing Spondylitis Disease Activity Score (ASDAS) are used to assess axial symptoms in patients with PsA. Here, we assessed the performance of BASDAI and ASDAS in patients with PsA.
METHODS
Patients with active PsA in DISCOVER-1 and DISCOVER-2 (ClinicalTrials.gov: NCT03162796 and NCT03158285, respectively) with or without axPsA but with available baseline BASDAI information were analysed; those with investigator-identified axial symptoms and imaging-confirmed sacroiliitis comprised the axPsA cohort. Correlations between BASDAI/ASDAS and clinical variables were assessed with Pearson's coefficient (). Longitudinal effects of enthesitis (Leeds Enthesitis Index [LEI]), swollen joint count and presence versus absence of axPsA on BASDAI/ASDAS (normalized 0-10 scale) were analysed with mixed models for repeated measures.
RESULTS
At baseline in the axPsA ( = 312) and non-axPsA ( = 124) cohorts, BASDAI scores showed no or weak correlation with swollen joint count (0.18-0.20), tender joint count (0.12-0.29), LEI (-0.04 to 0.24) and physician global assessment (0.35-0.43); moderate correlation with fatigue (both -0.56); and strong correlation with patient global assessment of disease activity (0.62-0.69) and patient-reported pain (0.66-0.70). Similar correlations were observed for ASDAS. Axial involvement versus non-involvement was associated with higher BASDAI scores and ASDAS (all β ≥ 0.5), without differences between instruments; longitudinal associations between swollen joint count (β ≤ 0.06)/LEI (β ≤ 0.19) and BASDAI/ASDAS were clinically unimportant.
CONCLUSION
BASDAI and ASDAS performed similarly in patients with active PsA and axial involvement, independent of peripheral disease involvement, supporting their performance in assessing axial disease activity.

BACKGROUND
Patients with inflammatory bowel disease (IBD) may also experience extraintestinal manifestations (EIMs), which can affect various organ systems, and their occurrence is based on disease activity.
OBJECTIVES
To determine the prevalence of EIMs and their most common types among IBD patients from Saudi Arabia.
MATERIALS AND METHODS
This retrospective study included all IBD patients aged 14-80 years who visited the Gastroenterology and Hepatology clinics at King Fahad Medical City, Riyadh, between February 2017 and December 2022. The collected data included demographic characteristics, disease characteristics, EIMs, and treatment.
RESULTS
The study included 578 IBD patients, of which 65 (11.2%) had at least one EIM, with primary sclerosing cholangitis (46.2%) and sacroiliitis (16.9%) being the most common. Patients with ulcerative colitis were more likely to have EIMs than those with Crohn's disease (15.1% vs. 9%; = 0.026). Patients with ileocolonic (L3) Crohn's disease reported a higher prevalence of EIMs (7.5%) than those with other disease locations ( = 0.012), while in patients with ulcerative colitis, those with extensive colitis (E3) reported higher prevalence of EIMs (19.2%) ( = 0.001). Patients receiving 6 MP had a significantly high prevalence of EIMs ( = 0.014).
CONCLUSION
The prevalence of extraintestinal manifestations among IBD patients in Saudi Arabia is 11.2%. These findings suggest the need for clinicians to screen for EIMs and manage them early. Further research is needed to understand the mechanisms underlying EIMs for the development of more effective treatments.

Randomized Controlled Trial
OBJECTIVE
There is a paucity of data on long-term clinical responses in patients with non-radiographic axial spondyloarthritis (nr-axSpA) based on their baseline objective signs of inflammation such as MRI or C-reactive protein (CRP) levels. This study reports clinical outcomes up to 3 years of the C-axSpAnd trial, including safety follow-up extension (SFE) from Weeks 52 to 156, stratified by patients' baseline MRI and CRP status.
METHODS
C-axSpAnd (NCT02552212) was a phase 3, multicentre study that evaluated certolizumab pegol (CZP) in patients with active nr-axSpA who had active sacroiliitis on MRI and/or elevated CRP. In this post hoc analysis, efficacy outcomes are reported to Week 156 of C-axSpAnd for patients stratified according to their MRI and CRP status at Week 0 (MRI+/CRP-, MRI-/CRP+ and MRI+/CRP+).
RESULTS
Across all outcome measures, including major improvement in Ankylosing Spondylitis Disease Activity Score (ASDAS-MI) and Assessment of SpondyloArthritis international Society criteria ≥40% response (ASAS40), outcomes were generally sustained in SFE patients from Week 52 to Week 156. MRI+/CRP+ patients showed numerically higher or comparable responses relative to MRI-/CRP+ and MRI+/CRP- patients at Weeks 52 and 156; however, all three subgroups demonstrated substantial improvements from Week 0 (in CZP-randomised patients, ASDAS-MI at Week 156 [observed case]: MRI+/CRP+: 73.1%, MRI-/CRP+: 52.2%, MRI+/CRP-: 30.4%; ASAS40: MRI+/CRP+: 76.9%, MRI-/CRP+: 62.5%, MRI+/CRP-: 65.2%).
CONCLUSIONS
In patients with nr-axSpA and objective signs of inflammation, long-term clinical outcomes achieved after 1 year were generally sustained at 3 years across MRI+/CRP+, MRI-/CRP+ and MRI+/CRP- subgroups.

INTRODUCTION
Brucellosis is a common global zoonotic disease with a wide range of complex and nonspecific clinical manifestations that may lead to misdiagnosis and delayed treatment. Osteoarticular involvement is the most common complaint in brucellosis.
OBJECTIVE
This present study aims to describe the clinical and laboratory characteristics and treatment of brucellosis patients with arthritis and sacroiliitis.
METHODS
This retrospective descriptive study was performed on patients presenting to a teaching hospital in Kermanshah, Iran with a diagnosis of brucellosis from 2011 to 2019. The demographic and clinical characteristics, complications, laboratory findings, and treatment were recorded during the study period. Then, the difference in the collected data was investigated between brucellosis patients with and without arthritis or sacroiliitis.
RESULTS
Of 425 patients studied, 130 (30.58%) had osteoarticular involvement. Among them, 41 (9.64%) and 58 (13.6%) patients were diagnosed with arthritis and sacroiliitis, respectively. There were no significant demographic differences between patients with and without brucellar arthritis or sacroiliitis ( > 0.05). The patients with arthritis had a significantly higher frequency of arthralgia and radiculopathy ( ⩽ 0.05). Sacroiliitis was significantly more common in patients with arthralgia, neck pain, and low back pain, positive flexion-abduction-external rotation (FABER) test, radiculopathy, and vertebral tenderness compared to patients without sacroiliitis ( ⩽ 0.05), while fever and headache were significantly more common in patients without sacroiliitis ( ⩽ 0.05). The median Wright and 2-Mercapto Ethanol titers were higher in brucellosis patients with arthritis or sacroiliitis patients without arthritis or sacroiliitis, but the difference was not significant ( > 0.05). Synovial fluid had been analyzed in 20 cases. The mean white blood cell count, glucose, and protein level were 3461 ± 2.70 cells/mm, 58.54 ± 31.43 mg/dL, and 8.6 ± 11.85 g/dL, respectively. In 80% of the subjects, neutrophil cells were predominant. There were no significant laboratory differences between patients with and without brucellar arthritis or sacroiliitis, except for a higher median platelet count in patients with arthritis and higher median levels of aspartate aminotransferase (AST) and alkaline phosphatase (ALP) in patients with sacroiliitis. Most cases of arthritis and sacroiliitis were diagnosed with ultrasound (31.8%) and FABER test (79.3%), respectively.
CONCLUSION
Arthritis and sacroiliitis were the two most important and common manifestations of brucellar osteoarthritis with a frequency of 9.64% and 13.6%, respectively. Any complaints of low back pain and radiculopathy as well as the presence of spondylitis in patients should raise suspicion of sacroiliitis. High levels of AST and ALP and a high platelet count may be associated with brucellar sacroiliitis and arthritis, respectively. The use of imaging methods such as MRI and bone scan seems necessary for the diagnosis of sacroiliitis.
