Alpha-gal syndrome-Food or drug allergy: A case report.

Alpha-gal syndrome is an immunoglobulin E-mediated hypersensitivity characterized by delayed allergic reactions to ingested products containing alpha-gal carbohydrate. We present a patient with recurrent urticaria and suspected repaglinide hypersensitivity, who was eventually diagnosed with alpha-gal syndrome, wanting to emphasize possible drug allergy misdiagnosis and required caution with the medication choice.

Delphi-Based Consensus on Interstitial Lung Disease Screening in Patients with Connective Tissue Diseases (Croatian National-Based Study).

The aim of this study was to develop a Croatian Delphi-based expert consensus for screening interstitial lung disease (ILD) associated with connective tissue disease (CTD). A systematic literature review was conducted on risk factors for the development of ILD, prevalence and incidence of ILD, diagnostic and screening methods for ILD, and prognosis of ILD in idiopathic inflammatory myopathy (IIM), mixed connective tissue disease (MCTD), primary Sjögren's syndrome (pSS), rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and systemic sclerosis (SSc) were performed. Based on the evidence found, experts developed questionnaires for screening and monitoring ILD in each CTD, which were provided via an online survey. Following the electronic survey, two screening algorithms were developed based on the consensus opinions. The detection strategy for ILD included high-resolution computed tomography (HRCT) in addition to pulmonary function testing for IIM, MCTD, and SSc. and pulmonary function testing for newly diagnosed pSS, RA and SLE. However, in patients with identified risk factors for ILD HRCT, these tests should also be performed. A screening strategy for early identification of patients with various CTD-ILD was first developed by a multidisciplinary team of rheumatologists, pulmonologists, and radiologists to identify early CTD patients at risk of ILD, a severe extra-articular manifestation of CTD.

Clinical efficacy and safety of adalimumab versus etanercept in patients with ankylosing spondylitis and total spinal ankylosis in Croatia: a multicentre 12-month follow-up study.

OBJECTIVE: To evaluate the 12-month efficacy and safety profile of adalimumab and etanercept in patients with ankylosing spondylitis (AS) and total spinal ankylosis (TSA). TYPE OF STUDY DESIGN: Case-series follow-up study. DESIGN: Twenty-eight patients (26 men and 2 women) with active AS (BASDAI > 4) and TSA were treated as follows: 19 patients receiving adalimumab and 9 patients receiving etanercept. Twelve-month data related to the efficacy and safety of these two TNF-alpha inhibitors were evaluated. The primary endpoint was ASAS 20 (the ASsessment in AS International Working Group criteria for 20% improvement) at weeks 12 and 52. Other measures that were evaluated were function (BASFI), disease activity (BASDAI), patient's and physician's global disease assessment on visual analogue scale (VAS) and C-reactive protein. RESULTS: In both adalimumab and etanercept groups, there was a significant improvement in all observed variables (baseline compared to weeks 12 and 52). This improvement was sustained for the whole follow-up period. In the adalimumab group, at week 12, ASAS 20 was achieved in 18/19 patients and at week 52 in 17/19 patients. In the etanercept group, at week 12 ASAS 20 was achieved in all patients and at week 52 in 6/9 patients. CONCLUSION: In patients with active AS and TSA, adalimumab and etanercept treatment showed significant improvement in function and disease activity. No serious side effects or adverse effects were observed in our cohort. Key Points • TNF-alpha inhibitors can be effective treatment options for patients with AS and having total spinal ankylosis. • Patients with advanced AS should not be disregarded as good candidates for treatment with biologic disease-modifying antirheumatic drugs.

Phenotype of limited cutaneous systemic sclerosis patients with positive anti-topoisomerase I antibodies: data from the EUSTAR cohort.

OBJECTIVES: To characterize patients with positive anti-topoisomerase I (ATA) in lcSSc. METHODS: SSc patients enrolled in the EUSTAR cohort with a disease duration of ≤3 years at database entry were considered. We assessed the risk of major organ involvement in the following groups: ATA-lcSSc vs ACA-lcSSc and vs ANA without specificity (ANA)-lcSSc, and ATA-lcSSc vs ATA-dcSSc. Cox regression models with time-dependent covariates were performed with the following outcomes: new-onset interstitial lung disease (ILD), ILD progression [forced vital capacity (FVC) decline ≥10% and ≥5% vs values at ILD diagnosis), primary myocardial involvement (PMI), pulmonary hypertension (PH), any organ involvement and all-cause mortality. RESULTS: We included 1252 patients [194 ATA-lcSSc (15.5%)], with 7.7 years (s.d. 3.5) of follow-up. ILD risk was higher in ATA-lcSSc vs ACA- and ANA-lcSSc and similar to ATA-dcSSc, although with less frequent restrictive lung disease. The risk of FVC decline ≥10% (35% of ATA-lcSSc) was lower in ATA-lcSSc than in ATA-dcSSc, whereas FVC decline ≥5% occurs similarly between ATA-lcSSc (58% of patients) and other SSc subsets, including ATA-dcSSc. The risk of PMI was similar in ATA-lcSSc and ANA-lcSSc but lower than in ACA-lcSSc; no difference in PH and mortality risk was observed among lcSSc subsets. The risk of any organ involvement, PMI and PH was lower and the mortality tended to be lower in ATA-lcSSc vs ATA-dcSSc. CONCLUSION: ATA-lcSSc patients have a high risk of ILD, albeit with a lower risk of progression compared with ATA-dcSSc, supporting careful screening for ILD in this subgroup.

Very Early Diagnosis of Systemic Sclerosis in Clinical Practice - Case Report and Review of the Literature.

Systemic sclerosis (SSc) is a systemic autoimmune disease characterised by generalized microangiopathy and fibrosis of skin and internal organs. The 2013 American College of Rheumatology (ACR) / European League Against Rheumatism (EULAR) criteria have contributed considerably to classifying patients with SSc in earlier stages, but they still lack sensitivity for a very early stage of the disease. Criteria for a very early diagnosis of SSc (VEDOSS) have been proposed by EULAR Scleroderma Trial and Research group (EUSTAR) which include three red flags: Raynaud's phenomenon, puffy fingers and antinuclear antibody positivity, plus SSc specific antibodies positivity and/or abnormal nailfold capillaroscopy. We report a case of a 54-year-old female patient with 6-week history of puffy fingers, Raynaud phenomenon and positive antinuclear antibodies. Further workup revealed early pathologic capillary pattern by nailfold capillaroscopy and positive anticentromere antibodies. Screening for internal organ involvement detected no heart, lung, or upper gastrointestinal tract involvement. The patient was started on pentoxifylline with further follow-up. The aim of the implementation of VEDOSS criteria is to diagnose SSc at the earliest possible stage, so that subclinical internal organ involvement could be detected and appropriate treatment started at a potentially reversible stage.

Association of polymorphisms in promoter region of TNF-α -238 and -308 with clinical outcomes in patients with immune-mediated inflammatory diseases on anti-TNF therapy.

The hypothesis of the study was that polymorphisms in promoter regions -238 and -308 of TNF-α could be associated with different clinical outcomes in inflammatory bowel diseases (IBD) and immune-mediated rheumatic diseases (IMRD). The aim was to examine the possible association of both polymorphisms with concentration of C-reactive protein (CRP) and fecal calprotectin (fCAL), onset of the remission and development of the ADA in patients on therapy with anti-TNF inhibitors. The prospective study was done in patients with IBD and IMRD on infliximab (IFX) or adalimumab (ADM). Patients were genotyped for TNF-α -238 and -308 polymorphisms. The concentration of CRP, fCAL, IFX or ADM and antibodies to drugs were measured according to manufacturer's instructions and followed-up for 6 or 12 months. Out of all patients (N = 112), number of patients in remission did not differ according to genotypes (for IBD patients P = 0.509 vs 0.223; for IMRD patients P = 0.541 vs 0.132 for TNF-α -238 and -308, respectively). Initial CRP concentration was higher in IBD patients with TNF-α -308 GG than GA/AA genotypes in patients who failed to achieve remission [11.8 (4.4-39.6) vs 3.1 (1.5-6.5), P = 0.033]. In IBD patients with remission, fCAL concentration after at least 6 months of therapy was higher in TNF-α-308 GG than in GA genotype [52 (25-552) vs 20 (20-20) µg/g, P = 0.041]. Our results showed the association of TNF-α -308 GG genotype with a higher concentration of CRP and fecal calprotectin in patients with inflammatory bowel diseases on IFX or ADM therapy. Clinical remission and development of antibodies to anti-TNF drugs were not associated with TNF-α -238 and -308 polymorphisms.

The Onset of Systemic Oxidative Stress Associated with the Accumulation of Lipid Peroxidation Product Acrolein in the Skin of Patients with Small-Vessel Vasculitis.

Small-vessel vasculitis (SVV) is the inflammation of the vessel wall that can result in hemorrhage and/or ischemia. Among the histological findings in SVV are increased infiltrating neutrophils, which, due to their oxidative burst and myeloperoxidase activity, release excessive reactive oxygen species, triggering a chain reaction of lipid peroxidation and yielding reactive aldehydes such as acrolein. The implication of oxidative stress in the pathogenesis of SVV was studied, focusing on acrolein immunohistochemistry in the affected skin vessels and systemic stress response. Samples from SVV patients and healthy subjects were collected and analyzed for total serum peroxides, total antioxidant capacity, inflammatory and immunological parameters, as well as for the presence of acrolein-protein adducts in the skin tissue specimens. The obtained data showed that systemic redox homeostasis and iron metabolism are altered in SVV patients. Possible biomarkers in the evaluation of oxidative status, disease activity and prevalence were indicated. Furthermore, a strong correlation between the accumulation of acrolein-protein adducts in the skin and the progression of the disease was revealed. Thus, the results of this study demonstrate that SVV is not only associated with systemic oxidative stress but also with tissue-specific oxidative stress that promotes acrolein formation and protein modification correlating with the severity of cutaneous vasculitis.

Treatment Satisfaction, Patient Preferences, and the Impact of Suboptimal Disease Control in a Large International Rheumatoid Arthritis Cohort: SENSE Study.

BACKGROUND: Patients' needs and perspectives are important determinants of treatment success in rheumatoid arthritis (RA). Assessing patients' perspectives can help identify unmet needs and enhance the understanding of treatment benefits. OBJECTIVE: The SENSE study assessed the impact of inadequate response to disease-modifying antirheumatic drugs (DMARDs) on treatment satisfaction, disease outcomes, and patient perspectives related to RA disease management. METHODS: SENSE was a noninterventional, cross-sectional study conducted in 18 countries across Europe, Asia, and South America. Adult patients with poorly controlled RA of moderate/high disease activity were eligible. Patient satisfaction was assessed by the Treatment Satisfaction Questionnaire for Medication (TSQM v1.4). Treatment adherence, healthcare resource utilization (HRU), quality of life (QoL), work ability, digital health literacy (DHL), patient preference information, and treatment strategy were also assessed. RESULTS: A total of 1624 patients were included in the study: most were female (84.2%) and middle-aged, and mean disease duration was 10.5 years. Mean TSQM global satisfaction subscore was 60.9, with only 13.5% of patients reporting good treatment satisfaction (TSQM global ≥80). The strongest predictor of good treatment satisfaction was treatment with advanced therapies. Most patients (87.4%) reported good treatment adherence. In general, patients had impaired QoL and work ability, high HRU, and 67.4% had poor DHL. Leading treatment expectations were "general improvement of arthritis" and "less joint pain". Most patients preferred oral RA medications (60.7%) and rapid (≤1 week) onset of action (71.1%). "Increased risk for malignancies" and "increased risk for cardiovascular disease" were the least acceptable side effects. Despite suboptimal control, advanced therapies were only used in a minority of patients, and DMARD switches were planned for only half of the patients. CONCLUSION: Suboptimal disease control negatively impacts treatment satisfaction, work ability, QoL, and HRU. Data collected on patient perspectives may inform shared decision-making and optimize treat-to-target strategies for improving patient outcomes in RA.

Effects of Yoga in Daily Life program in rheumatoid arthritis: A randomized controlled trial.

OBJECTIVES: To explore the feasibility and effectiveness of a yoga program in improving health-related quality of life (HQOL), physical and psychological functioning in rheumatoid arthritis (RA) patients. DESIGN: Single-centre parallel-arms randomized controlled trial comparing yoga (n = 30) and education control group (n = 27). SETTING: Tertiary care University hospital. INTERVENTION: A 12-week yoga program, based on the Yoga in Daily Life system, included 2x weekly/90-minute sessions. The control group had 1xweekly/60-minute educational lectures on arthritis-related topics. MAIN OUTCOME MEASURES: Assessments were performed at baseline, 12 (post-intervention) and 24 weeks (follow-up). The primary outcome was change in The Short Form-36 (SF-36) HQOL at 12 weeks. Linear regression analysis was adjusted for baseline scores. RESULTS: No significant between-group differences were found for SF-36 (all p > 0.05). At 12 weeks the adjusted mean difference between groups favoured yoga for Functional Assessment of Chronic Illness Therapy-fatigue (5.08 CI 1.29 to 8.86; p = 0.009) and Hospital Anxiety and Depression Scale (HADS)-depression (-1.37 CI -2.38 to -0.36); p = 0.008) and at 24 weeks for HADS-anxiety (-1.79 CI -3.34 to - 0.23; p = 0.025), while the impact on fatigue was sustained (5.43 CI 1.33 to 9.54, p = 0.01). The program had no impact on RA disease activity. Feasibility outcomes included recruitment rate 16 %, retention 80.7 %, and adherence to yoga 87.5 vs 82.7 % for control. No serious adverse events were recorded. CONCLUSIONS: Yoga in Daily Life program was not associated with change in health-related quality of life of RA patients. Significant improvements in fatigue and mood were observed at postintervention and follow-up. This yoga program was found feasible and safe for patients and may complement standard RA treat-to-target strategy.

Influence of Biological Therapeutics on Patient-Reported Quality-Of-Life Outcomes (Whoqol-Bref), Functional Scores and Disease Activity among Croatian Patients with Rheumatoid Arthritis: Our Experience.

BACKGROUND: Rheumatoid arthritis (RA) is a chronic and disabling disease with a great impact on the quality of life (QOL). The aim of this study was to assess QOL and health in RA patients treated with biological disease-modifying drugs (bDMARDs) as opposed to those treated with conventional synthetic DMARDs (csDMARDs). We analysed four domains of QOL: physical health (D1), mental health (D2), social relationships (D3) and one's surroundings (D4); as well as general quality of life (W1), general state of health (W2), and disease activity and physical disability. SUBJECTS AND METHODS: Seventy-seven RA patients (group A=29 on bDMARDs, group B=48 on csDMARDs) were enrolled in the study. QOL was evaluated using WHO questionnaire (WHOQOL-BREF), disease activity using Disease Activity Score 28C-reactive protein (DAS28CRP) and functional status using Health Assessment Questionnaire (HAQ). RESULTS: There was no statistically significant difference of mean values in the four domains of QOL, nor in the general QOL, between groups A and B. There was also no statistically significant difference regarding RA activity (3.51 vrs 3.54, p=0.56). However, we have found that the variable of the general state of health domain was statistically significantly higher in group B (2.66 vrs 2.89, p=0.001), while HAQ was statistically significantly higher in group A (1.19 vrs 1.07, p=0.018), as well as the duration of RA (6.25vrs 3.75 years, p=0.0006). Statistically significant correlation was found between HAQ and W2, disease duration and D3 in group A and DAS28CRP and D1, D2, W2 and HAQ and D1 and D2 in group B. CONCLUSION: These findings suggest that the inclusion of bDMARDs in the treatment regimen was overdue, with RA already advancing with developed functional disability, which prevented the achievement of the primary goals of treatment: low disease activity or remission and the improvement of patient's QOL.

The effect of smoking on disease activity in rheumatoid arthritis - our experience.

The aim of this study was to investigate the association of smoking with disease activity, seropositivity, age and gender in patients with rheumatoid arthritis. We included 89 rheumatoid arthritis patients. All patients fulfilled the 2010 American College of Rheumatology/European League Against Rheumatism rheumatoid arthritis classification criteria. Activity of the disease was measured by Disease Activity Score 28-joint count C-reactive protein (DAS28CRP). The subjects were stratified into smoking and non-smoking groups and cross-sectionally analyzed. There were 24 (27%) smokers and 65 (73%) nonsmokers. The mean age of patients was 57.1±8.8 years. The mean DAS28CRP was 5.81 in the smoking group and 5.57 in the non-smoking group, without statistically significant difference between the two groups (p=0.148). Similarly, smokers did not differ significantly from non-smokers according to age (p=0.443), gender (p=0.274), rheumatoid factor positivity (p=0.231), anti-citrullinated protein antibody positivity (p=0.754) or seropositivity (p=0.163). In this study, we found no association between smoking status and disease activity, seropositivity, age or gender in rheumatoid arthritis patients. Furthermore, disease activity was not related to age, gender or seropositivity. Additional studies on the effects of smoking on rheumatoid arthritis activity are needed.

Do We Pay Enough Attention to Neuropathic Pain in Knee Osteoarthritis Patients?

The aim of the study was to determine the prevalence of neuropathic pain in knee osteoarthritis patients using painDETECT questionnaire, and to evaluate correlations between pain intensity, gender, age and types of treatment, and the presence of neuropathic pain. The study included 122 patients. All participants completed a questionnaire on sociodemographic data, duration of symp-toms, types of treatment and preventable risk factors (body mass index and waist circumference). The presence of neuropathic pain was assessed by painDETECT, according to which subjects were classified into three groups (neuropathic pain likely, possible, or unlikely). Neuropathic pain was likely in 18 (14.8%), possible in 30 (24.6%) and unlikely in 74 (60.7%) subjects. A significant positive correlation was found between visual analog scale for pain and painDETECT score. There was no statistically significant difference in gender, age, waist circumference and body mass index among three groups of participants according to painDETECT score. In conclusion, knee osteoarthritis patients with neuropathic pain component were experiencing higher levels of pain, implicating poorer pain control with common analgesics. Recognizing these patients as a distinct subgroup would allow clinicians to improve their treatment by using unconventional analgesics with central activity.

Validity of the rheumatoid arthritis impact of disease (RAID) score and definition of cut-off points for disease activity states in a population-based European cohort of patients with rheumatoid arthritis.

OBJECTIVES: To assess the validity of the rheumatoid arthritis impact of disease (RAID) for measuring disease activity of rheumatoid arthritis (RA) and to determine cut-off values for defining the disease activity states. METHODS: A total of 622 RA patients from an European database have been included. Cross-validation was based on assessment of convergent and discriminant validity. Optimal cut-offs were determined against external criteria by calculating the respective 25th and 75th percentiles mean values of RAID. External criteria included definitions for remission (REM), low disease activity (LDA), moderate disease activity (MDA) and high disease activity (HDA), cut-offs of the 28-joint disease activity score-C-reactive protein (DAS28-CRP) score. RESULTS: The RAID showed a moderate degree of correlation with respect to DAS28-CRP (rho=0.417; P<0.0001). The receiver operating characteristic (ROC) curves to discriminate the ability of RAID to distinguish patients with active and non-active disease was very good with an area under the curve (AUC) of 0.847 (95% confidence interval [CI]: 0.816 to 0.878; P<0.0001). Based on the distributions of RAID in the different disease activity groups, we propose the following cut-off values for REM: RAID ≤3; for LDA: RAID >3 and ≤4; for MDA: RAID >4 and ≤6; for HDA: RAID >6. Mean RAID differed significantly between patients classified as REM, LDA, MDA or HDA (P=0.001). CONCLUSIONS: The cut-offs revealed good measurement characteristics in cross-validation analysis, had great discriminatory performance in distinguishing patients with different levels of disease activity and are suited for widespread use in everyday practice application and research.

European multicentre pilot survey to assess vitamin D status in rheumatoid arthritis patients and early development of a new Patient Reported Outcome questionnaire (D-PRO).

OBJECTIVE: To collect data on vitamin D (25(OH)D) serum levels in a large number of rheumatoid arthritis (RA) patients from different European countries, to investigate their relation with disease activity, disability, quality of life, and possibly to construct a new Patient Reported Outcome (PRO) questionnaire in order to self-estimate if they are at risk for vitamin D insufficiency/deficiency-related clinical implications (D-PRO). METHODS: This was a European League Against Rheumatism (EULAR) supported cross-sectional study (project No CLI064) which involved 625 RA patients (mean age 55±11years, mean disease duration 11±9years), 276 age and sex matched healthy subjects, and rheumatologists working in academic institutions or hospital centres, as well as PARE organizations (patient representatives) from 13 European countries. Serum samples for 25(OH)D level measurement were collected during winter time and analyzed in a central laboratory using chemiluminescence immunoassay (DiaSorin). Patient past medical history was recorded. RA patients were provided with three questionnaires: the Rheumatoid Arthritis Impact Diseases score (RAID), the Health Assessment Questionnaire (HAQ), and the new D-PRO questionnaire at the time of 25(OH)D serum sampling. D-PRO questionnaire consisted of three domains, Symptom Risk Score (SRS), Habitus Risk Score (HRS) and Global Risk Score (SRS+HRS=GRS), constructed with items possibly related to vitamin D deficiency. D-PRO was correlated with both clinical and PRO scores. DAS28-CRP was also evaluated. Statistical analysis was performed by non parametric tests. RESULTS: Mean serum concentration of 25(OH)D in RA patients (17.62±9.76ng/ml) was found significantly lower if compared to the levels obtained in matched controls (18.95±9.45ng/ml) (p=0.01), with statistically significant differences among several European countries. Negative correlations were found between 25(OH)D serum levels and DAS28-CRP (p<0.001), RAID (p=0.05) and HAQ (p=0.04) scores in the RA patients group. Negative correlations were also found in the cohort of enrolled RA patients between 25(OH)D serum concentrations and SRS (p=0.04), HRS (p=0.02) and GRS (p=0.02) domains of the D-PRO questionnaire. CONCLUSIONS: This first multicentre European survey add new evidences that vitamin D insufficiency/deficiency is frequent in RA patients with statistically significant differences among several countries. Vitamin D serum concentrations seem to correlate negatively and significantly with the D-PRO Global Risk Score, clinimetric indexes for quality of life, disease activity and disability in present cohort of RA European patients.

QuantiFERON-TB Gold In-Tube Test in the Diagnosis of Latent Tuberculosis Infection in Arthritis Patients Treated with Tumor Necrosis Factor Antagonists.

The aim of this study was to investigate the role of the QuantiFERON-TB Gold In-Tube test (QFT-GIT) in detecting latent tuberculosis in immunocompromised patients before introducing tumor necrosis factor (TNF-α) antagonists. The study included 300 subjects of similar age. The study group comprised of 150 QuantiFERON (QFT) positive subjects with rheumatoid arthritis, Crohn's disease, ulcerative colitis, ankylosing spondylitis and psoriatic arthritis, while control group comprised of 150 QFT negative respondents with the same diseases. Exhaustive medical history was documented for all patients. Screening tests were performed including QFT-GIT, tuberculin skin test (TST), chest radiography and detection of Mycobacterium tuberculosisin sputum culture 2 times. A positive QFT-GIT test result, regardless of TST result, was considered as an indication for latent tuberculosis infection (LTBI) treatment. Results of this study showed good correlation between the conclusive results of QFT-GIT and TST. All study group patients had normal clinical findings, normal radiologic findings and negative results of sputum microbiological analysis during the course of prophylaxis and after its completion and during the course of biological therapy. Conversion of positive QFT-GIT test to negative was observed in 4% of study group patients, while QFT negative respondents remained negative. There was a statistically significant positive correlation between QFTGIT, TST results and patient age, smoking habit and contact with tuberculosis. Study results showed that along with good clinical evaluation and detailed medical history, it is important to conduct testing in order to avoid disease progression or unnecessary isoniazid prophylaxis.

Ambulatory arterial stiffness index and carotid intima-media thickness in hypertensive rheumatoid patients: a comparative cross-sectional study.

AIM: Rheumatoid arthritis is associated with accelerated atherosclerosis. However, little is known about preclinical atherosclerosis in hypertensive rheumatoid arthritis patients. In this cross-sectional study we assessed the expression of preclinical atherosclerosis in hypertensive rheumatoid arthritis patients in comparison with matched hypertensive non-rheumatoid arthritis patients. METHODS: The study included 52 hypertensive rheumatoid arthritis patients and 42 hypertensive non-rheumatoid arthritis patients. The patients were extensively examined clinically and laboratory tested. The expression of preclinical atherosclerosis was estimated by assessing ambulatory arterial stiffness index and common carotid intima-media thickness. RESULTS: Arterial stiffness index and common carotid intima-media thickness were higher in hypertensive rheumatoid arthritis patients than in hypertensive non-rheumatoid arthritis patients. There was no correlation between arterial stiffness index and common carotid intima-media thickness with markers of inflammation and disease activity in hypertensive rheumatoid arthritis patients. CONCLUSION: The expression of subclinical atherosclerosis is more pronounced in hypertensive rheumatoid arthritis than in hypertensive non- rheumatoid arthritis patients.

[GRANULOMATOSIS WITH POLYANGIITIS (GPA) LIMITED TO UPPER RESPIRATORY TRACT--A CASE REPORT]. / GRANULOMATOZA S POLIANGIITISOM (GPA) I LOKALIZIRANIM ZAHVACANJEM GORNJEGA DISNOG SUSTAVA PRIKAZ BOLESNICE.

Granulomatosis with polyangiitis (Wegener's granulomatosis) is one of the anti-neutrophil cytoplasmic anti-body-associated small vessel vasculitides. Upper and lower respiratory system and kidneys are most commonly affected. The disease is characterized by granulomatous inflammation of the respiratory tract and necrotizing vasculitis of small to medium-sized blood vessels. Most patients show involvement of more than one organ systems at the time of diagnosis, and constitutional symptoms may be present. In around a quarter of patients the disease is initially localised, with involvement of upper respiratory tract or lungs. We report a 21-year-old female patient with chronic rhinitis, saddle nose deformity and subglottic stenosis who presented with inspiratory stridor and impending respiratory failure. Initially, urgent tracheotomy was performed. The patient was diagnosed with granulomatosis with polyangiitis limited to upper respiratory tract. Treatment with glucocorticoids and methotrexate was followed by clinical improvement.

Different Therapeutic Paths (Colchicine vs. Anakinra) in Two Patients With Schnitzler's Syndrome.

Schnitzler's syndrome is a rare autoinflammatory syndrome with unidentified mechanism of disease and etiology with unknown definitive treatment algorithm. The two obligatory criteria for the diagnosis of Schnitzler's syndrome include chronic urticarial rash and monoclonal gammopathy (immunoglobulin M or immunoglobulin G). In this article, we describe two patients with different courses of disease with different average lengths of time between initial symptoms and the final diagnosis (6 months to 8 years). Exclusion of more common conditions is needed to ensure the correct diagnosis. Treatment strategy depends on the patient's constitutional symptoms (fever, malaise, generalized myalgia, and arthralgias) and laboratory tests of inflammation. Treatment includes usage of conventional drugs and cytokine blockade (interleukin-1 and interleukin-6). Further studies are needed to determine the precise mechanism of disease and the appropriate targeted therapy.
