Abstract
Rheumatoid arthritis (RA) is a highly heritable complex disease with unknown etiology. Multi-ancestry genetic research of RA promises to improve power to detect genetic signals, fine-mapping resolution and performances of polygenic risk scores (PRS). Here, we present a large-scale genome-wide association study (GWAS) of RA, which includes 276,020 samples from five ancestral groups. We conducted a multi-ancestry meta-analysis and identified 124 loci (P < 5 × 10-8), of which 34 are novel. Candidate genes at the novel loci suggest essential roles of the immune system (for example, TNIP2 and TNFRSF11A) and joint tissues (for example, WISP1) in RA etiology. Multi-ancestry fine-mapping identified putatively causal variants with biological insights (for example, LEF1). Moreover, PRS based on multi-ancestry GWAS outperformed PRS based on single-ancestry GWAS and had comparable performance between populations of European and East Asian ancestries. Our study provides several insights into the etiology of RA and improves the genetic predictability of RA.

Abstract
BackgroundSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral load and its impact on disease outcome in patients with autoimmune rheumatic disease (ARD) are lacking. Also, whether patients with ARD receiving immunomodulators have different viral loads compared to the general population is unknown.ObjectivesTo compare the viral load of SARS-CoV-2 and its trending between patients without and with ARD.MethodsRetrospectively, patients with ARD infected with SARS-CoV-2 were matched by age and sex at a ratio of 1:2 to patients without ARD and not receiving immunosuppression or immunomodulator drugs. Viral load was determined by the cycle threshold (CT) value measured by a number of platforms: (a) Automated Platforms - the Roche Cobas 6800 system using the Cobas SARS-CoV-2 Test targeting the E and orf1a/b genes (Roche, Switzerland) and the Xpert Xpress SARS-CoV-2 targeting the E and N genes (Cepheid, USA); (b) Manual platforms - EZ1 (QIAGEN, USA), QIAsymphony (QIAGEN, USA), and Bioneer ExiPrepTM 96 Virus DNA/RNA kits Catalogue No K4614 (Bioneer, South Korea) extraction with thermal cycling using TaqPath™ PCR COVID-19 Combo Kit targeting the N, S and orf1a/b genes (Thermo Fisher Scientific, USA) on ABI 7500 thermal cyclers. Independent samples t-test was used to compare the mean CT values of the study groups at baseline and at 5 subsequent intervals (1 – 5.9, 6 – 11.9, 12 – 17.9, 18 – 23.9 and 24 – 30 days).ResultsMean age (SD) of 197 cases and 420 controls were 45.2 (11.8) and 44.1 (12.3) years, respectively. Females were predominant in both groups 60% vs. 52%, P=0.053. The most common ARD was rheumatoid arthritis in 82 cases (41.6%), followed by spondyloarthropathy in 33 (16.8%) and systemic lupus erythematosus in 31 (15.7%). Of the cases, 67% were on conventional synthetic disease modifying anti-rheumatic drugs (DMARDs), 15.2% on biological DMARDs and 4.6% patients were on rituximab. The mean CT values was significantly lower in the ARD group at baseline and persisted till day 24.Table 1.demographic characteristics and comparison of the mean CT values in the study groups at baseline and at different intervals with the corresponding OR (95% CI)Case (N=197)Control (N=420)OR (95% CI)Mean (SD) age, years45.2 (11.8)44.1 (12.3)1.008 (0.994–1.022)Sex, female N (%)120 (60.9%)221 (52.6)0.713 (0.505–1.006)Mean (SD) CT values at Baseline22.9 (5.5)30 (5.2)0.799 (0.745–0.858)1 – 5.9 days22.1 (4.6)25.7 (6.3)0.901 (0.842–0.963)6 – 11.9 days26.9 (4.9)31.5 (3.9)0.802 (0.724–0.888)12 – 17.9 days29.6 (4.1)32.3 (3.2)0.827 (0.743–0.921)18 – 23.9 days32.1 (4)32.9 (2.5)0.903 (0.728–1.119)24 – 30 days31.2 (1.2)32.7 (2.6)0.824 (0.589–1.151)ConclusionCompared to patients without ARD, the viral load of SARS-CoV-2 in patients with ARD is significantly higher at baseline testing and persists till day 24. This finding may indicate that patients with ARD are at higher risk of severe SARS-CoV-2 infection and prolonged potential transmission. Clinical outcome correlation is needed.ReferencesNoneDisclosure of InterestsNone declared

Abstract
BackgroundData on the extent of treat-to-target (T2T) recommendations application in SpA patients across Asia Pacific region is lacking. APLAR SpA Registry aimed to assess the utility of T2T on long term clinical outcomes, and to improve disease management and inform health care policy.ObjectivesTo provide a snapshot of the registry including demographics, disease activity and medication use.MethodsPatients fulfill the CASPAR 2006 for psoriatic arthritis (PsA) and 2009 ASAS criteria for axial spondylitis (AxSpA) were recruited. This cross sectional analysis included the first 188 patients recruited across 7 Asia Pacific regions (Hong Kong, Singapore, Korea, Thailand, India, Qatar & Pakistan).Results83 patients PsA and 115 AxSpA patients were included. They had moderate inflammation (DAPSA: 19.61±14.29, ASDAS: 2.32±1.07). Majority of PsA patients received conventional synthetic disease-modifying drug (csDMARDs, 81%) with relatively low prevalence of biologic DMARDs (bDMARDs) (24%). Most AxSpA patients used NSAIDs (79%) while nearly half of them received bDMARDs (49%). Other details listed in Table 1. Prevalence of bDMARDs use in our registry was lower than that from the USA (Corrona PsA Registry, 59%), Turkey & Canada (PsArt-ID, 40%) and the Netherlands AxSpA registry (56%) (1-3). Regarding T2T, 28% and 44% of PsA patient achieved minimal disease activity (MDA) and Disease Activity in Psoriatic Arthritis low disease activity (DAPSA LDA) respectively. The proportion of patients achieving target in other cohorts were 46% for MDA (PsArt-ID) and 46% for DAPSA LDA (Corrona) (1, 2). 37% and 47% of AxSpA patient achieved Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)<4 and Ankylosing Spondylitis Disease Activity Score (ASDAS) LDA. Proportion of patients achieving ASDAS LDA were similar to the Netherlands registry for patients with ASDAS LDA or BASDAI<4 (Figure 1A)(3). Patient on bDMARD were more likely to achieve treatment target (Figure 1B). There were no significant difference between socio-economic status and disease features between bDMARD user and non-user.Table 1.Demographics, clinical features and disease activity of patientsPsA (n=83)AxSpA (n=115)Age50.012.836.512.4Male n, %4251%8583%Asian n, %83100%10196%Disease duration, years7.17.35.27.6Any sacroiliitis n, %10299%HLA B27, positive n, %9189%Duration of early morning stiffness, min30392529Tender joint count7901Swollen joint count3400No. of dactylitis digit1100PASI4.05.0SPRACC1201BASDAI2.82.0ESR, mm/h31262016CRP, mg/L10151127HAQ-DI0.610.610.390.51DAPSA19.6114.29ASDAS CRP2.321.07Data given in mean SD unless stated.

Abstract
The diversity in our genome is crucial to understanding the demographic history of worldwide populations. However, we have yet to know whether subtle genetic differences within a population can be disentangled, or whether they have an impact on complex traits. Here we apply dimensionality reduction methods (PCA, t-SNE, PCA-t-SNE, UMAP, and PCA-UMAP) to biobank-derived genomic data of a Japanese population (n = 169,719). Dimensionality reduction reveals fine-scale population structure, conspicuously differentiating adjacent insular subpopulations. We further enluciate the demographic landscape of these Japanese subpopulations using population genetics analyses. Finally, we perform phenome-wide polygenic risk score (PRS) analyses on 67 complex traits. Differences in PRS between the deconvoluted subpopulations are not always concordant with those in the observed phenotypes, suggesting that the PRS differences might reflect biases from the uncorrected structure, in a trait-dependent manner. This study suggests that such an uncorrected structure can be a potential pitfall in the clinical application of PRS.

Abstract
OBJECTIVES There is limited information on the epidemiology and treatment patterns of rheumatoid arthritis (RA) across the Arab region. We aim in this study to describe the demographic characteristics, clinical profile, and treatment patterns of patients of Arab ancestry with RA. METHODS This is a cross sectional study of 895 patients with established rheumatoid arthritis enrolled from five sites (Jordan, Lebanon, Qatar, Kingdom of Saudi Arabia (KSA), and United Arab Emirates). Demographic characteristics, clinical profile, and treatment patterns are compared between the five countries. RESULTS The majority of our patients are women, have an average disease duration of 10 years, are married and non-smokers, with completed secondary education. We report a high (>80%) ever-use of methotrexate (MTX) and steroids among our RA population, while the ever-use of disease modifying anti-rheumatic drugs (DMARDs) and TNF-inhibitors average around 67% and 33%, respectively. There are variations in RA treatment use between the five country sites. Highest utilization of steroids is identified in Jordan and KSA (p-value < 0.001), while the highest ever-use of TNF-inhibitors is reported in KSA (p-value < 0.001). CONCLUSION Disparities in usage of RA treatments among Arab patients are noted across the five countries. National gross domestic product (GDP), as well as some other unique features in each country likely affect these. Developing treatment guidelines specific to this region could contribute in delivering standardized therapies to RA patients.

Abstract
Clinical practice guidelines can assist rheumatologists in the proper prescription of newer treatment for rheumatoid arthritis (RA). The objective of this paper is to report on the recommendations for the management of patients with RA in the Eastern Mediterranean region. We adapted the 2015 American College of Rheumatology guidelines in two separate waves. We used the adolopment methodology, and followed the 18 steps of the "Guidelines 2.0" comprehensive checklist for guideline development. For each question, we updated the original guidelines' evidence synthesis, and we developed an Evidence Profile (EP) and an Evidence to Decision (EtD) table. In the first wave, we adoloped eight out of the 15 original questions on early RA. The strength changed for five of these recommendations from strong to conditional, due to one or more of the following factors: cost, impact on health equities, the balance of benefits, and harms and acceptability. In the second wave, we adoloped eight out of the original 44 questions on established RA. The strength changed for two of these recommendations from strong to conditional, in both cases due to cost, impact on health equities, balance of benefits and harms, and acceptability. The panel also developed a good practice recommendation. We successfully adoloped 16 recommendations for the management of early and established RA in the Eastern Mediterranean region. The process proved feasible and sensitive to contextual factors.

Abstract
Objective To examine the prevalence of rheumatic manifestations among patients with
inflammatory bowel disease (IBD). Methods This prospective study enrolled patients with IBD in whom the diagnosis and
extent of IBD were confirmed by colonoscopy and histopathology. Patients
were interviewed and examined by a rheumatologist. A complete
rheumatological examination, X-rays of the lumbosacral and sacroiliac joints
and HLA-B27 blood tests were performed. Results A total of 127 adult patients were recruited: 46 (36.2%) with Crohn’s disease
(CD) and 81 (63.8%) with ulcerative colitis (UC). Rheumatic manifestations
of any type were present in 57.5% (73 of 127 patients) with no significant
differences between CD and UC. Peripheral manifestations were present in
43.3% (55 of 127 patients), four patients (3.1%) had axial arthritis alone
and 14 patients (11.0%) had both types. Among those with peripheral
manifestations, five patients (7.2%) had type 1 arthritis (pauciarticular)
and one patient (1.4%) had type 2 arthritis (polyarticular). A higher
proportion of patients with CD had axial manifestations with or without
peripheral manifestations (eight of 46; 17.4%) compared with patients with
UC (10 of 81; 12.3%), but no difference was observed in patients with
peripheral manifestations alone. Conclusions Rheumatic manifestations in patients with IBD in Qatar are more prevalent
than in other regions of the world. Peripheral manifestations were more
prevalent than axial.

Abstract
Objective This study assessed the mode of application (oral, intravenous or subcutaneous (SC)) currently employed in the treatment of rheumatoid arthritis (RA) in patients from Qatar in comparison with patients' individual preferences for the mode of application of their treatment. Methods This study included 294 RA patients visiting three clinics at the main referral hospital in Qatar who were interviewed using a standard questionnaire to determine their preference of mode of application for their disease-modifying antirheumatic drug (DMARD) treatment in relation to their currently employed mode of application. Results The majority of patients were female (76%), and 93% of male patients and 61% of female patients in the study clinics were of a nationality other than Qatari. The highest patient preference recorded was for an oral therapy (69%), compared with injection (23%) and intravenous (8%) therapy. In total, 85% of patients expressed a preference to remain on oral therapy compared with 63% and 58% of intravenous and SC injection patients indicating a preference to remain on their current method of administration. Conclusions This high preference for oral therapies highlights the considerable need for incorporation of new oral targeted synthetic DMARD therapies into clinical practice within the region.

Abstract
BACKGROUND Patients with ankylosing spondylitis (AS), who by definition have radiographic sacroiliitis, typically experience symptoms for a decade or more before being diagnosed. Yet, even patients without radiographic sacroiliitis (i.e., nonradiographic axial spondyloarthritis [nr-axSpA]) report a significant disease burden. The primary objective of this study was to estimate the prevalence and clinical characteristics of nr-axSpA among patients with inflammatory back pain (IBP) in rheumatology clinics in a number of countries across the world. A secondary objective was to estimate the prevalence of IBP among patients with chronic low back pain (CLBP). METHODS Data were collected from 51 rheumatology outpatient clinics in 19 countries in Latin America, Africa, Europe, and Asia. As consecutive patients with CLBP (N = 2517) were seen by physicians at the sites, their clinical histories were evaluated to determine whether they met the new Assessment of SpondyloArthritis international Society criteria for IBP. For those who did, their available clinical history (e.g., family history, C-reactive protein [CRP] levels) was documented in a case report form to establish whether they met criteria for nr-axSpA, AS, or other IBP. Patients diagnosed with nr-axSpA or AS completed patient-reported outcome measures to assess disease activity and functional limitations. RESULTS A total of 2517 patients with CLBP were identified across all sites. Of these, 974 (38.70 %) fulfilled the criteria for IBP. Among IBP patients, 29.10 % met criteria for nr-axSpA, and 53.72 % met criteria for AS. The prevalence of nr-axSpA varied significantly by region (p < 0.05), with the highest prevalence reported in Asia (36.46 %) and the lowest reported in Africa (16.02 %). Patients with nr-axSpA reported mean ± SD Ankylosing Spondylitis Disease Activity Scores based on erythrocyte sedimentation rate and CRP of 2.62 ± 1.17 and 2.52 ± 1.21, respectively, indicating high levels of disease activity (patients with AS reported corresponding scores of 2.97 ± 1.13 and 2.93 ± 1.18). Similarly, the overall Bath Ankylosing Spondylitis Disease Activity Index score of 4.03 ± 2.23 for patients with nr-axSpA (4.56 ± 2.17 for patients with AS) suggested suboptimal disease control. CONCLUSIONS These results suggest that, in the centers that participated in the study, 29 % of patients with IBP met the criteria for nr-axSpA and 39 % of patients with CLBP had IBP. The disease burden in nr-axSpA is substantial and similar to that of AS, with both groups of patients experiencing inadequate disease control. These findings suggest the need for early detection of nr-axSpA and initiation of available treatment options to slow disease progression and improve patient well-being.

Abstract
Osteoporosis is a disease that affects the bones. It leads to increased risk of fractures as a result of decreased bone mineral density. The goal of this study was to assess the general perception of osteoporosis as well as knowledge of lifestyle, risk factors, and preventive measures among patients in Qatar. The study was conducted between September 2013 and September 2014. The study subjects (n = 93) were patients diagnosed with osteoporosis who attended the Outpatient Rheumatology Clinic at Hamad General Hospital in Doha, Qatar. The results showed that those with a university or graduate degree had a significantly higher level of knowledge about osteoporosis (p = 0.009) than those with less education. Among those in our study, knowledge related to osteoporosis was principally obtained through media sources such as television and radio (39%). In conclusion, osteoporosis patients in Qatar need a better understanding of the disease. Identifying thought patterns related to the perception of osteoporosis and treatment might assist in building a foundation for management modalities and effective preventive strategies for the disease in Qatar.

Abstract
Axial spondyloarthritis (SpA) is a spectrum of inflammatory disease with stages characterized by both nonradiographic and radiographic sacroiliitis. Nonradiographic axial SpA is associated with health-related quality-of-life impairment and may progress to ankylosing spondylitis. Axial SpA has a low prevalence in some countries in North Africa and the Middle East, and pooling of data and resources is needed to increase understanding of the regional picture. Early diagnosis and effective treatment are required to reduce disease burden and prevent progression. Anti-TNF therapy is recommended for patients with persistently high disease activity despite conventional treatment, and has been shown to be effective in patients without radiographic damage. Diagnostic delays can be an obstacle to early treatment and appropriate referral strategies are needed. In some countries, restricted access to magnetic resonance imaging and anti-TNF agents presents a challenge. In this article, a group of experts from North Africa and the Middle East evaluated the diagnosis and management of axial SpA with particular reference to this region.

Abstract
BACKGROUND We assessed the effects of reduction and withdrawal of treatment in patients with rheumatoid arthritis who had a remission while receiving etanercept-plus-methotrexate therapy. METHODS Patients with early active disease who had not previously received methotrexate or biologic therapy received 50 mg of etanercept plus methotrexate weekly for 52 weeks (open-label phase). We then randomly assigned patients who had qualifying responses at weeks 39 and 52 to receive 25 mg of etanercept plus methotrexate (combination-therapy group), methotrexate alone, or placebo for 39 weeks (double-blind phase). Patients who had qualifying responses at week 39 of the double-blind phase had all treatment withdrawn at that time and were followed to week 65 (treatment-withdrawal phase). The primary end point was the proportion of patients with sustained remission in the double-blind phase. RESULTS Of 306 patients enrolled, 193 underwent randomization in the double-blind phase; 131 qualified for the treatment-withdrawal phase. More patients in the combination-therapy group than in the methotrexate-alone group or the placebo group met the criterion for the primary end point (40 of 63 [63%] vs. 26 of 65 [40%] and 15 of 65 [23%], respectively; P=0.009 for combination therapy vs. methotrexate alone; P<0.001 for combination therapy vs. placebo). At 65 weeks, 28 patients (44%) who had received combination therapy, 19 (29%) who had received methotrexate alone, and 15 (23%) who had received placebo were in remission (P=0.10 for combination therapy vs. methotrexate alone; P=0.02 for combination therapy vs. placebo; P=0.55 for methotrexate alone vs. placebo). No significant between-group differences were observed in radiographic progression of disease. Serious adverse events were reported in 3 patients (5%) in the combination-therapy group, 2 (3%) in the methotrexate-alone group, and 2 (3%) in the placebo group. CONCLUSIONS In patients with early rheumatoid arthritis who had a remission while receiving full-dose etanercept-plus-methotrexate therapy, continuing combination therapy at a reduced dose resulted in better disease control than switching to methotrexate alone or placebo, but no significant difference was observed in radiographic progression.

Abstract
OBJECTIVES The aim of this study is to investigate bone mineral density (BMD) for a large cross-section of midlife Arab women living in Qatar and to evaluate the association of body mass index (BMI), menopause status, and nationality, on BMD of the spine and femur. STUDY DESIGN A cross-sectional study was conducted among women aged 40-60 years recruited from nine primary-care health centers in Qatar. BMD (g/m(2)) was assessed at the lumbar spine and the femur. RESULTS The combined prevalence of osteopenia and osteoporosis was 4% at the femur and 16.2% at the spine. BMI and menstrual status were both independently associated with BMD at the spine and at the femur (all p values < 0.001). As BMI increased, BMD increased at both the spine and femur. Women who menstruated in the past 12 months had 0.82 g/cm(2) and 0.61 g/cm(2) greater BMD at the spine and femur, respectively, compared with women who had not menstruated in 12 months. Nationality was not associated with mean BMD of the spine or the femur. CONCLUSIONS No significant differences were observed between Qatari and non-Qatari women in terms of mean BMD values at the spine and the femur except for the femur in the age group 55-60, where values were lower among non-Qataris (p = 0.04). Multivariable analyses showed that BMI and menstrual status were found to be strongly associated with BMD levels at the spine and femur. The high prevalence of obesity observed in this sample may explain the low levels of osteopenia and osteoporosis observed.

Abstract
Background and objectives: Vitamin D deficiency is very common in pregnant women. Deficiencies have been prevalent even in studies where over 90% of the women took prenatal vitamins. The current guidelines for vitamin D intake during pregnancy of 200–400 IU has little scientific support and has been recently challenged. We conducted this study to determine the prevalence of vitamin D deficiency among pregnant women and to evaluate the effectiveness and level of weekly oral 50,000 IU of vitamin D supplementation for the mother and the newborn. Setting and design: Prospective study at Hamad Medical Corporation outpatient unit and delivery room. Patients and Methods: Ninety seven pregnant women were recruited in their first trimester between December 2007 and March 2010. Weekly oral vitamin D (50,000 IU) were prescribed after an initial testing for serum level of 25-hydroxyvitamin D, parathyroid hormone, calcium, phosphorus, total protein and albumin. Other multivitamins supplementations were allowed during pregnancy. The same tests were repeated at each trimester. Umbilical cords vitamin D levels were determined at birth. Results: Out of 97 patients, 8 patients dropped out from the study for several reasons, and 19 patients had pregnancy loss. Data were available for 97 women in the first trimester, 78 women in the second trimester and 61 women in the third trimester. The mean level of vitamin D level in the first trimester and prior to starting vitamin D supplementation was 17.15 ng/ml, 29.08 ng/ml in the second trimester, 27.3 ng/ml in third trimester and 22.36 ng/ml in newborns. There were no toxic levels of vitamin D in any of the women at the second or third trimesters or in the newborns. The mean levels of vitamin D in the second and third trimester were not significantly different in those women who were taking multivitamin supplementation and those who were not. Conclusion: Weekly doses of 50,000 vitamin D during pregnancy maintains acceptable vitamin D level during pregnancy and the newborn's vitamin D level correlates with the mother's levels.

Abstract
OBJECTIVE To describe the clinical characteristics, serologic, radiological and clinical disease activity, and modality of therapy in patients with rheumatoid arthritis (RA) at tertiary outpatient care in Qatar. METHODS The study design was cross-sectional where 100 consecutive cases who met 1987 American College of Rheumatology criteria for diagnosis of RA were enrolled in this study. Demographic data (sex, nationality and age) numbers of swollen and tender joints, X-rays and current medications were collected during outpatients visits to Hamad General Hospital. Disease Activity Score of 28 joints (DAS28) and Health Assessment Questionnaires (HAQ) scores were calculated. All patients with RA who were seen as rheumatology outpatients were invited to participate in the study. RESULTS One hundred patients were seen and examined during their follow-up at the outpatient clinic; data were collected and analyzed. Females represented 67% of all patients, 6% had more than six swollen joints, 9% had more than six tender joints. DAS28 and erythrocyte sedimentation rate (DAS28) calculation revealed 49% of patients were in remission (DAS28 < 2.6), 15% had low disease activity (DAS28 2.6-3.2) and 36% had DAS28 > 3.2.Mean HAQ score was 1.02. Rheumatoid factor (RF) was positive in 63%, while anti-cyclic citrullinated protein antibody (anti-CCP) was positive in 71%, and 49% were positive for both. Radiography of hands and feet during the previous year was done in 65% of patients: 11% of them had erosions. Sixty-six percent were on one synthetic disease-modifying anti-rheumatic drug (DMARD) and 27% where on more than one synthetic DMARD and 7% where on no DMRD. Glucocorticoids were used in 51% and 29% were on biologics. CONCLUSION Sixty-four percent of rheumatoid arthritis patients in Qatar were in remission or had low disease activity while the remaining 36% had active disease and among these patients 29% were on biologics.

Abstract
OBJECTIVES To investigate the relationships between inflammation, nocturnal back pain and fatigue in ankylosing spondylitis (AS) and the impact of 12 weeks' etanercept treatment versus sulfasalazine or placebo. METHODS Data were combined from four clinical trials for patients with AS who received at least one dose of etanercept, sulfasalazine or placebo and had at least one postbaseline assessment value. Linear regression was performed (controlling for site, protocol and demographics), to explore the relationship between inflammation (C-reactive protein [CRP]), nocturnal back pain (visual analog scale [VAS] 0-100 mm) and fatigue (VAS 0-100 mm Bath AS Disease Activity Index fatigue item). RESULTS Out of 1283 patients (etanercept, n = 867; sulfasalazine, n = 187; placebo, n = 229), improvement in nocturnal back pain was a significant predictor of improvement in fatigue. Significant correlations were found between nocturnal back pain and fatigue, but not CRP levels. Etanercept provided significantly greater pain/fatigue improvement than sulfasalazine or placebo. Improvements in nocturnal back pain and fatigue had weak relationships with improvement in inflammation (CRP level). CONCLUSIONS AS patients treated with etanercept demonstrated superior improvement in nocturnal back pain and fatigue versus sulfasalazine or placebo. Decrease in nocturnal back pain can improve fatigue. Assessing treatment response using CRP levels alone may be misleading without also examining patient-reported outcomes such as back pain and fatigue.

Abstract
The utilization of coronary angiography and percutaneous coronary intervention in the routine care for patients with acute coronary syndromes (ACS) has resulted in significant improvement in their prognosis. Consequently, recommendations on the use of these management strategies are reflected in the ACC/AHA guidelines for the management of patients with unstable angina and myocardial infarction. However, among other causes, the 'phobia' of nephrotoxicity of iodinated contrast media (ICM) in chronic kidney disease (CKD) patients and its claimed adverse effect on shortterm and longterm survival has led to a worryingly low use of ICM-based diagnostic and therapeutic interventions in patients with CKD. We argue that the fear of iodinated contrast media-induced acute kidney injury (ICI-AKI) is not a valid reason to avoid ICMbased investigations/interventions in CKD patients with ACS; the risks of myocardial infarction and death greatly outweigh the risk of ICI-AKI in most of these patients and hence they should always be considered for myocardial revascularization.

Abstract
This first update of the ASAS/EULAR recommendations on the management of ankylosing spondylitis (AS) is based on the original paper, a systematic review of existing recommendations and the literature since 2005 and the discussion and agreement among 21 international experts, 2 patients and 2 physiotherapists in a meeting in February 2010. Each original bullet point was discussed in detail and reworded if necessary. Decisions on new recommendations were made — if necessary after voting. The strength of the recommendations (SOR) was scored on an 11-point numerical rating scale after the meeting by email. These recommendations apply to patients of all ages that fulfill the modified NY criteria for AS, independent of extra-articular manifestations, and they take into account all drug and non-drug interventions related to AS. Four overarching principles were introduced, implying that one bullet has been moved to this section. There are now 11 bullet points including 2 new ones, one related to extra-articular manifestations and one to changes in the disease course. With a mean score of 9.1 (range 8-10) the SOR was generally very good.

Abstract
Background: Early detection and treatment of Hepatitis C can change the natural history of disease.
Aim: The primary aim of this study was to detect infection of hepatitis C using a rapid immunochromatographic assay in a community setting. The secondary aims included assessment of prevalence rate and disease characteristics; including liver function tests, viral load, grade and stage of disease on the liver biopsy.
Methods: Two cohorts of 4000 and 321 2 people (.004% of the population) were surveyed over a three week period each between December 2008 through August 2009. Qualitative detection of hepatitis C antibodies was done using a colloidal gold enhanced rapid immunochromatographic assay (Health Chem Diagnostics LLC, FL-USA).Viral load was calculated using RT PCR (Taqman) and those found positive underwent liver biopsy.28 and 33patients with proven chronic hepatitis C formed the controls for validation of the kit used in the first and the second cohort.

Abstract
Background: Cellular and animal studies suggest that hypercholesterolemia contributes to Alzheimer disease (AD).
However, the relationship between cholesterol and dementia at the population level is less clear and may vary over the lifespan.
Methods: The Prospective Population Study of Women, consisting of 1,462 women without dementia aged 38–60 years, was initiated in 1968–1969 in Gothenburg, Sweden. Follow-ups were conducted in 1974–1975, 1980–1981, 1992–1993, and 2000–2001. All-cause dementia was diagnosed according to DSM-III-R criteria and AD according to National Institute of Neurological and Communicative Disorders and Stroke, Alzheimer's Disease, and Related Disorders Association criteria. Cox proportional hazards regression examined baseline, time-dependent, and change in cholesterol levels in relation to incident dementia and AD among all participants. Analyses were repeated among participants who survived to the age of 70 years or older and participated in the 2000–2001 examination.

Abstract
The objective of this study was to analyze the factors predicting length of stay in a stroke patient rehabilitation unit at Hamad Medical Corporation (HMC) in Qatar. The medical rehabilitation data of 100 stroke patients discharged from a 15-bed inpatient rehabilitation unit (IPRU) were collected retrospectively from medical records during the period from September 2004 to April 2007. A questionnaire was developed, and variables included in the study were age of the patient, length of stay in acute care (LOSa), length of stay in rehabilitation (LOSr), functional independence measure on admission and discharge (FIMa and FIMd), modified disability scale, and modified mobility scale. Patients were grouped by impairments defined by cause as ischemic or hemorrhagic stroke, and right or left body side deficit. A significant negative correlation was observed between LOSr and FIMa (r = -0.44, p = 0.00), and positive correlation between LOSr and LOSa (r = 0.37, p = 0.00). There was no correlation between LOSr and FIMd (r = -0.03, p = 0.76). We observed that low admission FIMa and FIMd were related to extended LOS in both acute and IPRU. Multivariate regression analysis was performed by taking age, LOSa, cause of hemorrhage or ischemia, and FIMa as independent variables, and LOSr as dependent variable. The model could explain only 26% variation for LOSr. This study supports the hypothesis of an association between LOSr, LOSa, and FIMa. Further research is needed to confirm the results of this and other similar studies.

Abstract
A great variety of procedures have been proposed for the cure of sacrococcygeal pilonidal disease. A bilobed fasciocutaneous flap, based on the parasacral perforators, is described. This retrospective study was conducted to evaluate our experience with bilobed fasciocutanous flaps and to review current publications about flap surgery for the treatment of sacrococcygeal pilonidal sinus. Eight bilobed fasciocutanous flaps have been performed between February 2004 and September 2006. Eight males, aged 19 to 35 years (mean age: 26.2 years), presented with chronic and recurrent pilonidal disease. The duration of the disease was ranged from 2 to 6 years (mean age: 3.8 years). The sinuses were excised in a vertical, elliptical fashion and the defect closed using a bilobed fasciocutanous flap. This flap was designed using the parasacral perforators and tailored to obliterate the midline defect. Primary wound healing was achieved in all patients. Large defects after excision can easily be closed using the bilobed fasciocutaneous flap. The flap provides a tensionless wound closure. Hospitalisation is brief, and the postoperative course is comfortable. No recurrence was seen in any of the eight cases. This procedure is indicated in patients in whom wide skin resection is required, because of the tension-free skin closure in such cases. This technique enabled regional reconstruction, conserved tissues, and provided satisfactory aesthetic results. Therefore, this procedure can be considered an additional, useful tool in the treatment of pilonidal sinus.

Abstract
Background: Since some patients with psoriatic arthritis do not respond to typical drug treatments, alternatives are needed. Findings suggest that interleukins 12 and 23 might affect clinical symptoms and pathological joint changes of psoriatic arthritis. Ustekinumab is a human monoclonal antibody that inhibits receptor-binding of these cytokines. We aimed to assess the efficacy and safety of ustekinumab for psoriatic arthritis in this phase II study.

Abstract
Background: Ecological and observational studies suggest that low Vitamin D status could be associated with higher mortality from life-threatening conditions including cancer, cardiovascular disease, and diabetes mellitus that account for 60% to 70% of total mortality in high-income countries. We examined the risk of dying from any cause in subjects who participated in randomized trials testing the impact of Vitamin D supplementation (ergocalciferol (Vitamin D2) or cholecalciferol (Vitamin D3) on any health condition.

Abstract
Background: Ten ASAS/EULAR recommendations for the management of ankylosing spondylitis (AS) were published in 2006. Objectives: (a) To disseminate and (b) to evaluate conceptual agreement with, and (c) application of, these recommendations as well as (d) potential barriers to the application. Methods: A questionnaire was sent to rheumatologists in 10 countries. It included (a) the text of the recommendations; (b) rheumatologists’ demographic variables; (c) two numerical rating scales from 1 to 10 for each recommendation: conceptual agreement with, and application of, the recommendation (10 indicates maximal agreement and maximal application); and (d) a list of potential barriers to the application of the recommendation. Statistical analysis included descriptive and multivariate analyses. Results: 7206 questionnaires were sent out; 1507 (21%) were returned. Of the 1507 answering rheumatologists, 62% were men, mean (SD) age 49 (9) years, and 34% had an academic position. Conceptual agreement with the recommendations was high (mean (SD) for all recommendations 8.9 (0.9)). Self-reported application was also high (8.2 (1.0)). The difference between agreement and application varied across recommendations and countries. The most pronounced discrepancies were reported for use of anti-tumour necrosis factor drugs in a few countries, with funding as the most commonly reported barrier for application of this recommendation. Conclusion: This large project has helped the dissemination of the ASAS/EULAR recommendations for the management of AS and shows that conceptual agreement with the recommendations is very high. The project also highlights inequalities in access to healthcare for European citizens with AS.

Abstract
Aim: To assess the exocrine pancreatic function among cystic fibrosis patients with cystic fibrosis trans-membrane conductance regulator (CFTR) 11234V mutation. METHODS: Cross-sectional study of 40 cystic fibrosis patients with homozygous CFTR 11234V mutation belonging to a large Arab kindred family and 25 healthy subjects as a control group over a period of 12 mo. Assessment of their exocrine pancreatic function was performed by measuring faecal elastase-1 (FE1) concentration with a commercial ELISA kit using polyclonal antibodies (BioServ Diagnostics) in CF patients compared to healthy subjects. The results were compared with those obtained from a second laboratory using another commercial ELISA (ScheBo; Biotech, Germany) that uses two monoclonal antibodies against different specific epitopes of human pancreatic elastase. RESULTS: All CF patients with CFTR 11234V mutation had normal levels of faecal elastase 1. No significant difference was found between the two methods for the CF groups or between the CF patients with and without pancreatic enzyme replacement.

Abstract
Osteonecrosis (ON) is a disease with significant morbidity, it is associated with multiple diseases. The aim of this study was to find out the characteristics of ON in Qatar.Methods: this is a retrospective study done at Hamad Medical Corporation, which is the main hospital in Qatar (Arabian Gulf) with 1300- bed capacity. Inpatients records from 1993 to 2003 with the diagnosis of ON and avascular necrosis (AVN) were reviewed. Patients’ characteristics were recorded.Results: 40patients records were reviewed;only 38 had complete records, the other two incomplete files excluded from the study. The patients'age ranged from 9 to 69 years old, 22 males and 16 female. Twenty patients were Qataris and eighteen were non-Qatari, Time to diagnosis ranged from six days to two years. Forty-seven total joints were affected (more than one joint was affected in eight patients). The hip was the most common site involved 39/ 47 and eight were a non-hip (four knees, three ankles and one wrist). Six (15.7%) patients were on steroids. Associated diseases were as follows: five (13%) patients had sickle cell anemia, seven (18.4%) patients had trauma, four (10.5%) patients had hematological diagnosis (one leukemia, one protein C deficiency, one polycythemia vera (PCV), and one TTP. One (2.6%) had nephrotic syndrome, one had reticular sarcoma of the femur; one had Hodgkin lymphoma with radiation, one patient had polymyositis, one had rheumatoid arthritis and one had systemic lupus erythematosus with nephritis. In 12 patients (31.5%) no obvious cause were found.Conclusions: this is the first study on ON in Qatar, there were some differences of the characteristics of our patients compared to others; notably less trauma and alcohol associations and more hematological association, this study may represent a local demographic data of ON in this region.
