Is Serum Uric Acid Level Associated with Disease Activity in Rheumatoid Arthritis Patients.

Background: An association between serum uric acid (UA) and disease activity in rheumatoid arthritis (RA) patients has not been well studied. We describe RA patients with high and normal UA and study its association with RA activity. Methods: Adult RA patients from the Kuwait Registry for Rheumatic Diseases (KRRD) were studied from February 2012 through March 2022. Patients with documented UA levels were included. UA of >357 µmol/L (6mg/dL) was considered high. Statistical comparison and correlation were made using multivariate logistic regression. Results: Overall, 1054 patients with documented UA. A total of 158 patients (15%) had high UA level with a mean of 409± 44.4µmol/L. The mean age for the high UA group and low UA group were 59.3 ± 10.7 years and 54.5 ± 12.4 years, respectively (p<0.001). 49.4% were female in high UA group, and 62.2% were female in low UA group, respectively (p<0.05). Logistic analysis showed an inverse relation between DAS28 and UA, as lower DAS28 score was associated with higher UA level (p=0.032) OR 1.39. There was a direct relation with HAQ, creatinine and UA. A higher HAQ is associated with a higher UA level (p=0.019) OR 0.78. High creatinine level is also associated with high UA level (p<0.001) OR 0.24. The use of antirheumatic drugs was similar among patients with high and normal UA. Conclusion: RA patients with a higher UA had a lower disease activity despite using similar antirheumatic drugs. The reasons behind this association need to be further studied.

Adherence to the Mediterranean diet is associated with a reduced DAS28 index among patients with rheumatoid arthritis: Case study from KRRD.

BACKGROUND: Rheumatoid arthritis (RA) is a chronic, autoimmune disease that mostly affects the synovial joints. It has been hypothesized that dietary and other environmental and lifestyle factors contribute to the development of RA and its severity. OBJECTIVE: The present study aims to measure the effect of the Mediterranean diet (MedDiet) on the disease activity scores (DAS28) among patients with RA. METHODS: Adult patients who satisfied the American College of Rheumatology (ACR) classification criteria for RA from major hospitals in Kuwait were evaluated. A cross-sectional study conducted on 754 RA patients visits aged (21-79) years. Patients were evaluated using the DAS28. Patients' levels of adherence to the MedDiet are assessed using a validated 14-item Questionnaire (paper or web-based). The data was analyzed using both multivariate and univariate statistics. Multivariate logistic regression was used to analyze the statistical relationship between MedDiet and RA disease activity. RESULTS: The finding suggests that a MedDiet can have a positive impact on DAS28 among patients with RA. In the DAS28 cohort (DAS28 < 3.2, DAS28 ≥ 3.2), several Mediterranean survey components showed statistically significant differences. Patients with a Mediterranean score ≤ 5 was more likely to have hazard effects for DAS28 than those with a Mediterranean score of ≥10 (HR = 0.17, CI [0.08-0.37], p < .001). The finding shows that, Mediterranean levels ≤5, on biologics treatment, CRP, and patient global assessment were significantly associated with overall survival. Additionally, the MedDiet was found to be a significant predictor of DAS28 in the random forest decision tree plot, along with tender, RF, and creatinine. MedDiet patients had a lower DAS28 score than others. CONCLUSION: The findings suggest that optimal drug treatment and a restrictive diet can help to improve DAS28 score for patients with RA. More patients in the cohort DAS28 <3.2 used olive oil, servings of vegetables, fruits, and legumes. In contrast, more patients in the cohort DAS28 ≥ 3.2 consumed red meat, butter, sweetened or soft drinks, cakes, cookies, or biscuits, and tomato sauce.

Eczema among adolescents in Kuwait: Prevalence, severity, sleep disturbance, antihistamine use, and risk factors.

Background: Eczema (atopic dermatitis) is a common inflammatory skin disease that is more prevalent in children and adolescents than adults. In Kuwait, there is a lack of empirical knowledge on eczema epidemiology among adolescents. Therefore, this study aimed to estimate the prevalence of eczema symptoms and severity, assess the frequency of eczema-related nocturnal sleep disturbance and its relation to antihistamine use, and determine factors that are associated with eczema prevalence and eczema-related nocturnal sleep disturbance. Methods: A school-based cross-sectional study enrolled adolescents (n = 3864) aged 11-14 years across Kuwait. Information on eczema symptoms and clinical history, use of antihistamines, parental history of eczema, mode of delivery, and childhood life-style factors and exposures were reported by parents. Current eczema was defined as chronic or chronically relapsing itchy dermatitis with characteristic morphology and distribution in the past 12 months. Among subjects reporting current itchy rash, frequency of nocturnal sleep disturbance due to itchy rash in the past 12 months was reported as: never, <1 night per week, and ≥1 nights per week. Associations were assessed by applying a modified Poisson regression to estimate adjusted prevalence ratios (aPR) and 95% confidence intervals (CI). Results: The prevalence estimate of current (past 12 months) itchy rash was 20.5% (735/3593) and current eczema was 10.2% (388/3791), with 19.5% (736/3775) reporting history of ever doctor-diagnosed eczema. Among subjects with current itchy rash, nocturnal sleep disturbance due to itchy rash affected 21.7% (157/724) of participants for <1 night per week and affected 12.7% (92/724) of participants for ≥1 nights per week. Antihistamine use at least once per month increased as the frequency of nocturnal sleep disturbance due to itchy rash increased (Ptrend <0.001). Factors that demonstrated association with current eczema prevalence included underweight body mass index (aPR = 1.71, 95% CI: 1.16-2.53), Cesarean section delivery (1.29, 1.01-1.65), and maternal (1.72, 1.35-2.19) and paternal (1.83, 1.44-2.32) history of eczema. Frequent (≥1 nights per week) nocturnal sleep disturbance was associated with Cesarean section delivery (1.98, 1.37-2.85), exposure to household tobacco smoke (1.70, 1.18-2.47), and dog-keeping (1.93, 1.06-3.52). Conclusions: Eczema symptoms are common among adolescents in Kuwait, with similar epidemiological patterns as those observed in western countries. A large proportion of affected adolescents reported nocturnal sleep disturbance due to itchy rash. Modifiable risk factors were associated increased prevalence of eczema and night awakenings.

Compartment syndrome following a jellyfish sting: a case report.

BACKGROUND: While the majority of reported cases of jellyfish envenomation are self-limited with few lasting complications, a few can cause life-threatening and debilitating illnesses. We present the case of a 15-year-old male who had an unusual presentation of a jellyfish sting that led to acute compartment syndrome. CASE PRESENTATION: A 15-year-old Lebanese (Arab) boy was stung by a jellyfish, which led to acute compartment syndrome in the left arm. Decompression fasciotomy and local application of diluted nitroglycerin helped to relieve the ulnar and radial artery spasms. The patient was left with shoulder and elbow pain and elbow flexion weakness, which improved after physiotherapy over a period of 6 weeks. CONCLUSIONS: Current therapy recommendations for acute compartment syndrome following jellyfish stings are mainly based on case reports. Urgent fasciotomy and local application of nitroglycerin have been demonstrated to be helpful in severe jellyfish stings associated with acute compartment syndrome.

Noninvasive High-Frequency Oscillatory Ventilation: A Retrospective Chart Review.

OBJECTIVE: This study aimed to review the feasibility of nasal high-frequency oscillatory ventilation (NHFOV) in preventing reintubation in preterm infants. STUDY DESIGN: This is a retrospective cohort study of all premature newborn infants placed on NHFOV in a single-center neonatal intensive care unit. RESULTS: Twenty-seven patients (birth weight: 765 ± 186 g, gestational age: 28 ± 2 weeks) were commenced on NHFOV on 32 occasions. NHFOV was used immediately postextubation as the primary mode of noninvasive ventilation (NIV; prophylaxis) in 10 of 32 occasions and as "rescue" (failure of NCPAP or biphasic CPAP) in 22 of 32 occasions. Treatment with NHFOV was successful in 22 occasions (69%) while on 10 occasions (31%) reintubation was required within 72 hours. In the rescue group, there was significant reduction in the mean (standard deviation [SD]) number of apneas (0.9 ± 1.07 vs. 0.3 ± 0.29, p < 0.005), but there were no significant changes in the PCO2 level (52 [ ± 9.8] vs. 52 [ ± 8.6] mm Hg, p = 0.8), or the FiO2 requirement (0.39 ± 0.19 vs. 0.33 ± 0.10, p = 0.055) before and after commencing NHFOV, respectively. CONCLUSION: The use of NHFOV is feasible as a prophylactic or rescue mode of NIV following extubation and was associated with decrease in the number of apneas without significant changes in PCO2 or oxygen requirements. A well-designed randomized control trial is needed to determine the indications, clinical outcomes, and safety of this treatment modality. KEY POINTS: · NHFOV is a new and evolving mode of noninvasive ventilation.. · The use of NHFOV is feasible as a prophylactic or rescue mode of noninvasive ventilation.. · A well-designed randomized control is needed to evaluate the efficacy and safety of NHFOV safe..

Rheumatologic Aspects of the COVID-19 Pandemic: A Practical Resource for Physicians in Kuwait and the Gulf region as Recommended by the Kuwait Association of Rheumatology.

The Kuwait Association of Rheumatology members met thrice in April 2020 to quickly address and support local practitioners treating rheumatic disease in Kuwait and the Gulf region during the coronavirus disease 2019 (COVID-19) pandemic. Because patients with rheumatic and musculoskeletal disease (RMD) may need treatment modifications during the COVID-19 pandemic, we voted online for the general guidance needed by local practitioners. In this review, we have addressed patients' vulnerability with rheumatic disease and issues associated with their optimum management. Our recommendations were based on the formulation of national/international guidelines and expert consensus among KAR members in the context of the Kuwaiti healthcare system for patients with RMD. The most recent reports from the World Health Organization, the Center for Disease Control, the National Institutes of Health-National Medical Library, and the COVID-19 educational website of the United Kingdom National Health Service have been incorporated. We discuss the management of RMD in various clinical scenarios: screening protocols in an infusion clinic, medication protocols for stable patients, and care for patients with suspected or confirmed COVID infection and whether they are stable, in a disease flare or newly diagnosed. Further, we outline the conditions for the hospital admission. This guidance is for the specialist and non-specialist readership and should be considered interim as the virus is relatively new, and we rely on the experience and necessity more than evidence collection. The guidance presented should be supplemented with recent scientific evidence wherever applicable.

Debriefing: A Tool to Enhance Education and Practice in NICU.

Debriefing, a facilitator-guided reflection of an educational experience or critical incident, is an important tool in improving the safety and quality of practice in the NICU. Unlike feedback, which is often a one-way discussion, debriefing is a purposeful, 2-way reflective discussion which is based on experiential learning theory. The purpose of this article is to review the theoretical basis of debriefing and describe styles and tools for debriefing that can be applied in the NICU.

Don't close the book on tocilizumab for the treatment of severe COVID-19 pneumonia-the jury is still out: The Kuwait experience.

PURPOSE: This cross-sectional observational study aims to report preliminary data from the first experience using tocilizumab for patients with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection in three of Kuwait's largest public hospitals City. PATIENTS AND METHODS: This chart review study examined the benefits of tocilizumab treatment among 127 patients diagnosed with severe coronavirus disease of 2019 (COVID-19) pneumonia. RESULTS: 90 of 127 patients (71%) survived. Mortality was highest in the elderly with multiple medical conditions. CONCLUSION: Despite the small sample size and retrospective nature of the work, our findings are consistent with recent studies suggesting tocilizumab administration in patients presenting with severe COVID pneumonia with associated hyperinflammatory features conferred mortality benefit.

Accessibility to biologics and its impact on disease activity and quality of life in patients with rheumatoid arthritis in Kuwait.

OBJECTIVE: Biologics are indicated in rheumatoid arthritis (RA) in case of persistent high disease activity despite conventional disease-modifying anti-rheumatic drugs (cDMARDs) or patients with contraindications to cDMARDs or poor prognostic factors. The purpose of this study was to compare the prescription rates of biologics in Kuwaiti and non-Kuwaiti patients and to assess whether this had an impact on disease activity and quality of life in RA patients. METHODS: Data were extracted from the Kuwait Registry for Rheumatic Diseases. Adult patients who satisfied the ACR classification criteria for RA from four major hospitals in Kuwait were evaluated from February 2013 through May 2018. The treatment agents, disease activity, and quality of life of Kuwaiti patients were compared with non-Kuwaiti patients. RESULTS: A total of 1651 RA patients were included; 806 (48.8%) were Kuwaiti patients. Among Kuwaiti patients, 62.5% were on biologic drugs in comparison with 14% of non-Kuwaiti patients. In comparison with non-Kuwaiti patients, Kuwaiti patients had significantly lower numbers of swollen joints (p < 0.001) and disease activity score-28 scores (p = 0.02) and less steroid use (p < 0.001) yet a significantly higher health assessment questionnaire-disability index (p < 0.001). Regression analysis showed that DAS-28 scores were significantly associated with the treatment type (p < 0.001) and that nationality was significantly predictive of the treatment type (p < 0.001). CONCLUSION: In the setting of easy accessibility to treatment for Kuwaiti patients, biologics were prescribed by rheumatologists at a higher rate than for non-Kuwaitis. This may explain the lower disease activity and the lower rate of steroid use in Kuwaiti patients than non-Kuwaitis. KEY POINTS: • Significant discrepancies in the rates of prescribing biologic therapies between KP and NKP in Kuwait were observed. • Several treatment outcomes were significantly better in the KP group than in the NKP group even after adjustment of confounding factors. • The poor access to biologic therapies was suggested to limit the effectiveness of RA treatments in the NKP group.

The treatment journey for patients with axial spondyloarthritis in North Africa and the Middle East: From diagnosis to management.

The management of axial spondyloarthritis (axSpA) is challenging worldwide, and the particular challenges shared by North Africa and the Middle East are mainly related to early diagnosis and standardized management. We believe there are several reasons for these challenges, including: (a) limited awareness of the disease manifestations and prevalence in the region among physicians; (b) the concept of nonradiographic axSpA, while accepted with some difficulty by the rheumatology community, may not be well understood by the referring primary care physicians; (c) access to, and training in magnetic resonance imaging varies greatly between countries in the North Africa and Middle East region, and this may have a large impact on early diagnosis; (d) country-specific treatment guidelines are unavailable; and (e) economic and cultural factors influence patients' attempts to seek and continue treatment. In this review, we will discuss the prevalence of axSpA in North Africa and the Middle East, as well as the challenges to diagnose and treat patients in this region. As rheumatologists practicing in North Africa and the Middle East, we also provide suggestions to assist physicians, other healthcare professionals, and researchers in facilitating early, accurate diagnosis and treatment of axSpA.

Recommendation for the Management of Spondyloarthritis Patients in Kuwait.

OBJECTIVE: In 2016, ASAS and EULAR made joint recommendations for the management of patients with spondyloarthritis. Although Global and European perspectives are important, they cannot accurately reflect the situation for all patients in all countries and regions. As such, the group worked to tailor the existing international recommendations to suit the specific demographic needs of local populations in the Gulf region, with a specific focus on Kuwait. METHODS: Recommendations drafted following a PubMed search for relevant literature were reviewed and then underwent Delphi vote to reach consensus on those to be included. Advice for newly approved agents, including targeted synthetic disease-modifying anti-rheumatic drugs, was included based on the group's clinical experience. RESULTS: The resulting 41 recommendations are grouped into five categories covering key definitions and principles for the management and treatment of both axial and peripheral forms of spondyloarthritis. CONCLUSION: Through adaptation of existing guidelines and incorporating the current evidence and clinical experience of the members of the group, these recommendations have been developed to reflect the unique situation in Kuwait with regard to differing patient profiles, local culture and approved therapeutic approaches, and are designed to aid in clinical decision-making.

Psoriasis Among Adolescents in Kuwait and the Role of Siblings, Breastfeeding, and Household Cat and Secondhand Smoke Exposure: A Cross-Sectional Study.

INTRODUCTION: Globally, the epidemiology of psoriasis is poorly understood, and most countries lack essential epidemiologic data regarding disease burden and its determinants. This study sought to estimate the prevalence of psoriasis among adolescents in Kuwait and assess its association with different risk factors, including obesity, sibship size, breastfeeding, and exposure to household secondhand smoke (SHS) and pets. METHODS: Schoolchildren aged 11-14 years (n = 3864) were enrolled in a cross-sectional study. Lifetime and current (past 12 months) prevalence of psoriasis were ascertained according to ever having a history of doctor-diagnosis plus current active lesion(s) and/or current use of treatment of psoriasis. Associations were assessed using Poisson regression with robust variance estimation, and adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) were estimated. RESULTS: The lifetime and current prevalence of psoriasis were estimated to be 3.6% (136/3806) and 1.1% (42/3806), respectively. Commonly reported anatomical sites affected by psoriasis included scalp (47.6%) and the extensor surface of the knees (50%) and elbows (38.1%). Household SHS exposure was associated with increased lifetime psoriasis (aPR = 1.41, 95% CI 1.07-1.98), and showed a trend for association with current psoriasis (1.77, 0.89-3.53). Similarly, cat-keeping during infancy was associated with lifetime psoriasis (1.96, 1.14-3.37), and demonstrated a trend for association with current psoriasis (1.49, 0.52-1.98). In contrast, breastfeeding was associated with a decreased lifetime psoriasis (0.62, 0.44-0.89), but was not associated with current psoriasis. Trend analyses showed that the prevalence of lifetime and current psoriasis increased with increasing numbers of total, older, and younger siblings. CONCLUSIONS: Psoriasis affects a considerable proportion of schoolchildren in Kuwait. Interestingly, psoriasis prevalence was related to risk factors also found in allergic diseases, such as exposure to SHS, cat-keeping in infancy, breastfeeding, and sibship size, possibly suggesting a role of immune dysregulation.

Rhinoconjunctivitis among Adolescents in Kuwait and Associated Risk Factors: A Cross-Sectional Study.

Rhinoconjunctivitis is a public health problem that causes major illness and disability worldwide. Epidemiological studies intended to determine the burden of rhinoconjunctivitis in Kuwait are limited. Hence, this study sought to estimate the prevalence of rhinoconjunctivitis among adolescents in Kuwait and explore its association with different risk factors. Schoolchildren aged 11-14 years (n = 3,864) were enrolled in a cross-sectional study. Parents completed questionnaires regarding their children's clinical history and symptoms of rhinoconjunctivitis and relevant exposures. Associations were assessed using Poisson regression with robust variance estimation, and adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs) were estimated. The 12-month (current) prevalence estimates of rhinitis, rhinoconjunctivitis, and severe rhinoconjunctivitis were 28.6% (1,040/3,643), 13.5% (497/3,689), and 1.2% (44/3,689), respectively. The prevalence of current rhinoconjunctivitis symptoms was higher in boys compared to girls (aPR = 1.19, 95% CI: 1.01-1.41). Parental history of rhinitis and asthma showed positive associations with rhinoconjunctivitis in offspring. Trend analyses showed that rhinoconjunctivitis prevalence decreased with increasing numbers of total siblings (aPR = 0.92, P trend < 0.001) and older siblings (aPR = 0.90, P trend < 0.001). Rhinoconjunctivitis is common among adolescents in Kuwait and its epidemiology is similar to that found in western countries.

Kuwait association of rheumatology 2018 treatment recommendations for patients with rheumatoid arthritis.

The Kuwait Association of Rheumatology (KAR) aimed to develop a set of recommendations for the treatment of patients with rheumatoid arthritis (RA), tailored to the unique patient population and healthcare system of Kuwait. Each recommendation was developed based on expert opinion and evaluation of clinical practice guidelines from other international and national rheumatology societies. Online surveys were conducted to collate feedback on each KAR member's level of agreement (LoA) with definitions of disease-/treatment-related terms used and the draft recommendations. Definitions/recommendations achieving a pre-defined cut-off value of ≥ 70% agreement were accepted for inclusion. Remaining statements were discussed and revised at a face-to-face meeting, with further modifications until consensus was reached. A final online survey was used to collect feedback on each KAR member's LoA with the final set of recommendation statements on a scale of 0 (complete disagreement) to 10 (complete agreement). Group consensus was achieved on 66 recommendation statements, including 3 overarching principles addressing the pharmacological treatment and management of RA. Recommendations focused on treatment of early RA, established RA, patients with high-risk comorbidities, women during pregnancy and breastfeeding, and screening and treatment of opportunistic infections. The KAR 2018 Treatment Recommendations for RA reported here are based on a synthesis of other national/international guidelines, supporting literature, and expert consensus considering the Kuwaiti healthcare system and RA patient population. These recommendations aim to inform the clinical decisions of rheumatologists treating patients in Kuwait, and to promote best practices, enhance alignment and improve the treatment experience for patients.

Integrated evaluation of hemodynamics: a novel approach for the assessment and management of preterm infants with compromised systemic circulation.

OBJECTIVE: To establish normal reference values for tissue oxygen delivery and consumption in preterm infants and demonstrate the usefulness of the integrated evaluation of hemodynamics (IEH) in preterm infants with compromised systemic circulation (CSC). METHODS: This study included 32 stable preterm infants and 6 infants (selected cases) who underwent IEH. IEH is a multimodal approach which integrates clinical parameters: data obtained from near-infrared spectroscopy (NIRS) and targeted neonatal echocardiography (TNE). RESULTS: Thirty-two hemodynamically stable preterm infants underwent 57 IEH studies. The mean (10th and 90th percentiles) were 0.23 (0.14 and 0.29) for cerebral fractional oxygen extraction (crFOE), 0.2 (0.13 and 0.24) for renal fractional oxygen extraction (rnFOE), and 0.22 (0.19 and 0.27) for mesenteric fractional oxygen extraction (msFOE). The time to full clinical recovery in all sick infants after the change of management was between 4 and 48 h. CONCLUSION: IEH was useful in targeting the management of preterm infants with CSC.

Kuwait Recommendations on Vaccine Use in People with Inflammatory Rheumatic Diseases.

People with IRD are at increased risk of infection, and in 2011 EULAR made general recommendations for vaccination in these patients. Global and European perspectives are important, but they cannot accurately reflect the individual situations of patients in different countries and regions. Based on our clinical experience and opinions, we have sought to tailor the original EULAR recommendations to include advice for vaccination with new agents approved in the intervening years-including the new class of targeted synthetic disease-modifying antirheumatic drugs. We have also considered the specific demographic needs of patients in local populations in the Gulf region. The resulting 16 recommendations are grouped into four main categories covering general vaccination guidelines and best-practice for all patients with IRD, followed by a set of recommended vaccines against specific pathogens. The last two categories include recommendations for certain patient subgroups with defined risks and for patients who wish to travel.

Low Prevalence of Nodules in Rheumatoid Arthritis Patients in Kuwait: A Description and a Comparison of Patients from the Kuwait Registry for Rheumatic Diseases.

OBJECTIVES: To describe the prevalence of rheumatoid nodules (RN) in patients with rheumatoid arthritis (RA) and to compare their features with those of patients without RN. SUBJECTS AND METHODS: Adult RA patients (n = 952) in the Kuwait Registry for Rheumatic Diseases from February 2013 to December 2015 were evaluated for RN. Demographic and serological features and disease activity and severity were obtained from the registry. RESULTS: Of the 952 RA patients, 22 (2.3%) had RN and 930 (97.7%) did not. Age, sex, disease duration, smoking, and family history of an autoimmune rheumatic disease were similar. Obesity was more prevalent in the RN group, i.e. 11 (50%) vs. 326 (35.1%), p = 0.016. There was no difference in rheumatoid factor (RF) or anti-cyclic citrullinated peptide antibody positivity. Patients with RN had more sicca symptoms, i.e. 8 (36.4%) vs. 152 (16.3%), p = 0.025, a higher mean score on the visual analogue scale pain (3 ± 2.9 vs. 2 ± 2.7, p < 0.001), more tender joints (6.4 ± 8.8 vs. 4.2 ± 7.2, p = 0.001), a higher patient global assessment of disease activity (3.3 ± 2.7 vs. 2.3 ± 2.7, p < 0.001), and more deformities, i.e. 3 (13.6%) vs. 74 (8%), p = 0.034. The mean health assessment questionnaire score in RN patients was 1.1 versus 0.9 in patients without RN (p = 0.08). Patients with RN had a low disease activity (means: disease activity score [DAS-28], 3.02; clinical disease activity index, 7.7; and simple disease activity index, 10.4), similar to the other group. While the rates of methotrexate treatment were comparable, biologic therapy was administered more in patients with RN (i.e. 15 [68.2%] vs. 478 [51.4%], p < 0.001). CONCLUSION: In Kuwait, the prevalence of RN is low among RA patients. Patients with and without RN are similar in terms of demographics and serologic features, except for more obesity. However, patients with RN have more sicca symptoms, joint deformities, and painful and tender joints. Disease activity scores are low with more frequent biologic therapy.

Serum S100A12 and temporomandibular joint magnetic resonance imaging in juvenile idiopathic arthritis Egyptian patients: a case control study.

This study aimed to measure serum levels of the proinflammatory protein S100A12, investigate clinical as well as contrast enhanced magnetic resonance imaging findings of temporomandibular joint inflammation among juvenile idiopathic arthritis patients and to find out the correlation between each of them, moreover with different disease parameters as temporomandibular joint inflammation may occur without clinical manifestations; it is in need for thorough evaluation and S100A12 may be a future anti-inflammatory treatment in JIA. Twenty patients with Juvenile Idiopathic Arthritis (JIA) and 10 healthy control subjects underwent measurement of S100A12 serum concentrations by sandwich ELISA. Temporomandibular Joints (TMJs); clinical and post contrast Magnetic Resonance Imaging (MRI) examinations were performed. MRI findings were scored. Results showed that TMJ arthritis was detected in 80% of JIA patients using MRI. Serum S100A12 levels were significantly increased in patients compared to controls. Serum concentrations of S100A12 and total MRI scores were significantly higher in JIA patients with active disease compared to those without activity. Systemic and polyarticular JIA patients showed significant increase in S100A12 levels and total MRI scores compared to those with oligoarticular JIA. The MRI TMJ abnormalities revealed significant association with clinical signs of TMJ inflammation but not with symptoms. A significant correlation was found between serum S100A12 concentrations and MRI score as well as between each of them and different clinical, laboratory disease parameters. Serum S100A12 levels showed significant positive correlation with synovial enhancement score. To conclude TMJ arthritis could be detected in most cases of JIA patients using contrast enhanced MRI. Increased S100A12 levels may point to synovial inflammation. Clinical signs of TMJ arthritis may be used as filter for MRI examination. Further studies on larger scale of JIA patients are needed for monitoring TMJ inflammation and S100A12 may be a potential target of future anti-inflammatory therapy.

Can tumor necrosis factor inhibitors be safely used in pregnancy?

OBJECTIVE: We review available safety data for use of currently approved tumor necrosis factor (TNF) inhibitors during pregnancy and lactation and suggest guidelines for use of these agents among women of reproductive age. Method. Although regulatory agencies encourage the inclusion of pregnant women and those of child-bearing age in randomized controlled trials, pregnant and lactating women have universally been excluded from studies because of unknown or potential risks to the fetus. Thus, strong evidence-based treatment recommendations during pregnancy are usually lacking and safety information is derived from voluntary reports of adverse events during postmarketing surveillance or via uncontrolled, observational studies, reviewed here. RESULTS: Uncommon adverse pregnancy outcomes observed with TNF inhibitor therapy appear to approximate those seen in women not receiving such therapy and may include premature birth, miscarriage, low birthweight, hypertension, and preeclampsia. There are rare reports of fetal malformations or congenital anomalies in patients exposed to TNF inhibitors during conception or pregnancy. However, the incidence of these events appears to be far below the 3% rate of congenital anomalies in the general population. CONCLUSION: If the activity or disease severity precludes the cessation of a TNF inhibitor and/or DMARD, uncontrolled observations suggest that conception and early pregnancy are not adversely affected by use of TNF inhibitors. Nearly 70% of pregnant patients can discontinue their TNF inhibitor early in the pregnancy (or with determination of pregnancy) without augmenting maternal or fetal risks.
