    OBJECTIVE: To determine the prevalence, correlates and independent predictors of self-reported depression, anxiety and stress in Rheumatoid arthritis (RA) patients in Hospital Melaka.

    METHODS: This was a cross-sectional survey using convenient sampling of 192 RA patients who attended the Rheumatology Clinic outpatient appointment, Hospital Melaka from June 2013 to December 2013. Depression, Anxiety and Stress Scale (DASS21) questionnaire was used to evaluate symptoms of depression, anxiety and stress. RA disease activity was assessed using the DAS28-ESR formula. Functional status was assessed via the Health Assessment Questionnaire Disability Index (HAQ-DI).

    RESULTS: Out of 189 completed questionnaires, 46%(n=86) patients reported psychological distress symptoms, and 25%(n=48) experienced more than one negative emotional states. The prevalence of depression, anxiety and stress among our patients were 23.3%(n=44), 42.3%(n=80) and 20.1%(n=38) respectively. There were significant positive correlations (p<0.05) between these psychological symptoms with disease activity, number of tender joints, general health, pain and HAQ score. Age was inversely correlated with depression, anxiety and stress. Higher number of swollen joints correlated positively with depression but not with anxiety and stress. HAQ was the only independent predictor for depression (Odds Ratio [OR]=2.07; 95%CI: 1.19 to 3.61) and anxiety (OR=1.81; 95%CI: 1.1 to 3.0) whilst pain was found to be independent predictor for stress (OR=1.04; 95%CI: 1.0 to 1.1).

    CONCLUSION: The incidence of depression and anxiety in our Malaysian sample of RA patient was comparable to that observed in Caucasian populations. Functional status was an independent predictor of depression and anxiety, whereas pain was an independent predictor of stress.

    INTRODUCTION: Uncontrolled asthma may cause an increase in healthcare utilisation, hospital admission and productivity loss. With the increasing burden of asthma in Malaysia, strategies aimed at reducing cost of care should be explored.

    OBJECTIVE: This study aims to determine if a clinical pathway (CPW) for inpatient paediatric asthma would reduce average length of stay (ALOS), improve asthma management and decrease cost.

    METHODS: A quasi-experimental, pre-post study was used to evaluate the CPW effectiveness. Paediatric inpatients aged 5-18 years old, admitted for acute asthma exacerbation from September 2015 to April 2016 were prospectively recruited. Data from patients admitted from January-July 2015 were used as control. CPW training was carried out in August 2015 using standardised modules. Direct admission cost from the provider's prospective was calculated. Outcomes compared were differences in ALOS, discharge medication, readmission within 28 days of discharge and cost.

    RESULTS: ALOS is 26 hours lower in the CPW group for severe exacerbations and underlying uncontrolled asthma (19.2 hours) which is clinically significant as patients have shorter hospital stay. More newly-diagnosed intermittent asthmatics were discharged with relievers in the CPW group (p-value 0.006). None of the patients in the CPW group had readmissions (p-value 0.16). Mean treatment cost for patients in the intervention group is higher at RM843.39 (SD ±48.99, versus RM779.21 SD±44.33).

    CONCLUSION: This study found that management using a CPW may benefit asthmatic patients with uncontrolled asthma admitted with severe exacerbation. Further studies will be needed to explore CPW's impact on asthma management starting from the emergency department.

    INTRODUCTION: Hyponatraemia is the commonest electrolyte abnormality and has major clinical implications. However, few studies of hyponatraemia in the primary care setting has been published to date.

    OBJECTIVES: To determine the prevalence, potential causes and management of hyponatraemia and to identify factors associated with severity of hyponatraemia among older persons in a primary care setting.

    METHODS: Electronic records were searched to identify all cases aged ≥60 years with a serum sodium <135mmol/l, attending outpatient clinic in 2014. Patients' medical records with the available blood test results of glucose, potassium, urea and creatinine were reviewed.

    RESULTS: Of the 21,544 elderly, 5873 patients (27.3%) had electrolyte profile tests. 403 (6.9%) had hyponatraemia in at least one blood test. Medical records were available for 253, mean age 72.9±7.3 years, 178 (70.4%) had mild hyponatraemia, 75 (29.6%) had moderate to severe hyponatraemia. Potential causes were documented in 101 (40%). Patients with moderate to severe hyponatraemia were five times more likely to have a cause of hyponatraemia documented (p<0.01). Medications were the commonest documented cause of hyponatraemia (31.7%). Hydrochlorothiazide use was attributed in 25 (78.1%) of 32 with medication-associated hyponatraemia. Repeat renal profile (89%) was the commonest management of hypotonic hyponatraemia.

    CONCLUSION: Whilst hyponatraemia was common in the clinic setting, many cases were not acknowledged and had no clear management strategies. In view of mild hyponatraemia has deleterious consequences, future studies should determine whether appropriate management of mild hyponatraemia will lead to clinical improvement.

    INTRODUCTION: Numerous studies have found that a majority of systemic lupus erythematosus (SLE) patients have suboptimal vitamin D levels. The major contributory factor is most likely attributed to sun protection measures in order to avoid SLE flares. The objectives of this research included the assessment of vitamin D status and its association with clinical manifestations of SLE, cardiovascular risk factors, autoantibodies, SLE disease activity and damage accrual.

    METHOD: This retrospective study involved SLE patients who attended the Rheumatology Clinic at the Hospital Kuala Lumpur from January 2014 to December 2016. Vitamin D was categorised as normal, insufficient or deficient, and the clinical variables were compared across vitamin D categories with chi-squared tests and Pearson correlation coefficient.

    RESULTS: We included 216 patients. The mean 25(OH)D concentration was 51.3(Standard Deviation; SD 14.8) nmol/L. Fifty (23.1%) patients had vitamin D deficiency, 120 (55.6%) had vitamin D insufficiency, while 46 (21.3%) had adequate vitamin D levels. There were statistically significant associations between vitamin D status and ethnic group, lupus nephritis and hypertension. No correlations were observed between vitamin D status with SLEDAI score (Pearson correlation coefficient -0.015, p=0.829) as well as SDI score (Pearson correlation coefficient -0.017, p=0.801).

    CONCLUSION: SLE patients should be screened for vitamin D concentrations and their levels optimised.

    BACKGROUND: The COVID-19 is a disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This study aims to describe the clinical characteristics of COVID-19 patients admitted to Hospital Tengku Ampuan Afzan (HTAA), Pahang, Malaysia and to identify the clinical and laboratory markers for severe disease, complications and virologic clearance according to clinical staging.

    METHODS: This was a single-centre, retrospective, descriptive study. All COVID-19 patients admitted to HTAA from March 9 to April 15, 2020, were included in the study. Patients were categorised according to clinical staging. Data obtained from the medical report includes baseline characteristics of patients, comorbidities, presenting symptoms, laboratory findings, treatments, complications, and outcomes.

    RESULTS: Of the total of 247 patients hospitalised, the majority consisted at clinical-stage 1 (43%) and stage 2 (39%) disease. Older patients, diabetes mellitus, hypertension, cardiovascular diseases, and chronic kidney disease were found more common among patients with severe disease. Fever was uncommon and the majority had normal haemoglobin levels, white cell counts, and platelet counts. C-reactive protein (CRP) was found statistically significant to predict pneumonia or hypoxia at a cut-off value of 14mg/L (sensitivity 73.8%, specificity 91.3%) and 50mg/L (sensitivity 100%, specificity 96.4%) respectively. Pneumonia was mostly diagnosed radiologically using chest radiography, especially among clinical stage 3. Acute kidney injury (AKI) was a significant complication, with 31% of clinical stage 3 and above developed AKI and 44% of them requiring haemodialysis. Median virologic clearance time was 15 days from onset of illness, and asymptomatic patients had longer clearance time.

    CONCLUSION: COVID-19 presented with a wide spectrum of clinical patterns. CRP was a valuable predictor of severe disease. In this study risk and severity of acute kidney injury were found to be higher. A longer duration of virologic clearance was observed among the asymptomatic patients.

    INTRODUCTION: As the first point of contact for those presenting with asthma symptoms, primary healthcare plays a crucial role in asthma management. This is a nationwide study of assessment of asthma symptom control and adherence to asthma medication among outpatients in public health clinics in Malaysia.

    METHODS: This is a prospective, observational multicentre study (ASCOPE; NCT03804632). Data on asthma control, assessment of control symptoms, and adherence to treatment were collected from medical records and interviews of patients. The level of asthma control was assessed using the Global Initiative for Asthma (GINA) Assessment of Symptom Control. Adherence of patient to medication for asthma was assessed through interview of patients using four questions adapted from the Malaysian Medication Adherence Scale.

    RESULTS: Among the 1011 patients recruited, 416 (41%) had well controlled asthma, 388 (38%) were partly controlled, and 207 (21%) had uncontrolled asthma. Majority (81%) had mild asthma and all patients were on asthma medication. Most patients did not have spirometry data (97%) but underwent peak flow rate measurements (98%). Poor adherence occurred at all levels of asthma control but was worst among those with uncontrolled asthma. This was statistically significant across all four questions on adherence (p<0.05). For example, more patients with uncontrolled asthma forgot doses (56%) or stopped treatment (39%) than those with well-controlled asthma (44% and 27%respectively).

    CONCLUSIONS: Among Malaysian primary care patients with asthma, less than 50% had well-controlled asthma, and low adherence to treatment was common. More effort is needed to improve asthma control among patients in Malaysia, including those with mild asthma.

    INTRODUCTION: The COVID-19 pandemic has prompted the medical world to look at factors that may influence outcomes. There have been connections made between vitamin D and COVID-19, as vitamin D has previously been shown to play a role in the maintenance of immune homeostasis.

    MATERIALS AND METHODS: We performed a prospective cohort study on 103 patients at Wigan Wrightington and Leigh NHS Foundation Trust looking at serum vitamin D levels of patients with positive COVID-19 swabs. Results were collated and correlations were made to compare vitamin D levels with age; severity of illness; hospital outcomes; and frailty. Comparisons were also made between frailty and outcome.

    RESULTS: The results showed that there was a significant statistical difference between vitamin D levels and severity of infection: those who were treated in the intensive care units (ICU) (severe symptoms) had lower vitamin D levels than those treated on the ward (p=0.0446). There was also a correlation between vitamin D levels and frailty: those who were more frail had higher vitamin D levels than fitter patients (P=0.005). Vitamin D and frailty had no effect on hospital outcomes of COVID-19 infection.

    CONCLUSION: Ultimately, we concluded that low vitamin D can increase susceptibility of contracting COVID-19, increase severity of infection but does not affect mortality.

    A scoring system based on therapeutic intervention on critically ill patients called the therapeutic intervention scoring system (TISS) was used to assess the quantity of care provided in a medical intensive care unit. Besides observing the unit census, the severity of illness and the work load were studied. The survival rate was 77 percent. The non-survivors had admission TISS points higher than the survivors and their mean daily TISS was more than 20 points. The survivors at discharge had a mean TISS of five points. The work load showed that a nurse can effectively manage two patients who together may accumulate 24 TISS points per day. TISS points per patient rather than bed occupancy is a better indicator of the nurse's work load. Admission criteria and procedures before death certification are outlined.

    INTRODUCTION: Coronary artery calcification can lead to suboptimal results when performing coronary angioplasty with conventional techniques. The presence of severe coronary artery calcium increases the complications of percutaneous coronary intervention as it may impede stent delivery and optimal stent expansion. The purpose of this study was to determine the procedural success and safety of orbital atherectomy (OA) in calcified lesions.

    MATERIALS AND METHODS: This was a prospective single-centre study regarding the utility of OA in the treatment of calcified coronaries. Intravascular ultrasound (IVUS) or optical coherence tomography (OCT) was used in all cases to characterise the severity of calcium pre-procedure, guide vessel sizing and assess procedural success. The primary endpoint was procedural success, defined by successful stent implantation following OA treatment. The secondary endpoint was in-hospital and 30-day major adverse cardiovascular event (MACE).

    RESULTS: Ten patients with severely calcified lesions were successfully treated with OA. The primary endpoint was achieved in all patients. All of the lesions were severely calcified with concentric calcium. None of the patients suffered in-hospital or 30-day MACE. The average minimal luminal diameter at baseline was 1.7 ± 0.3 mm and the post- PCI luminal diameter was 3.0 ± 0.3 mm, with a significant luminal gain of 1.3 ± 0.3 mm (p < 0.01). Slow flow during procedure occurred in 2 (20%) cases and dissection occurred in 1 (10%) case during procedure. These were successfully treated with stent delivery to achieve TIMI III flow. There were no cases of stent thrombosis or vessel perforation.

    CONCLUSION: Our experience demonstrates the feasibility and safety of OA in the management of calcified coronary stenosis. Intravascular imaging is an important adjunct to the use of OA to assess the severity of calcified coronary lesions, success of OA treatment and to aid sizing of the vessel for stent implantation. OA is an effective treatment approach to disrupt coronary calcification, facilitating stent implantation with optimal results. It is a safe procedure with good success rate and low rate of complications.

    INTRODUCTION: Acne vulgaris (AV) is a common inflammatory skin disease affecting adolescents and young adults. It affects one's self-esteem and social relationship. In addition, poor adherence to treatment can cause poor treatment response and disease recurrence. This study aims to determine the effectiveness of medical education and counselling on treatment adherence and disease severity.

    METHODS: This is a non-randomised interventional study with age- and treatment- matched control conducted in a tertiary dermatology clinic from July 2021 to June 2022. Patients in the intervention group received a 10 min video presentation on acne, followed by treatment counselling. The adherence rate was determined objectively (pill counting and tube weighing) and subjectively (ECOB questionnaire). The disease severity was assessed using the Comprehensive Acne Severity Scale (CASS) and Global Acne Grading System (GAGS).

    RESULTS: A total of 100 patients completed the 12-week study. With intervention, patients have better adherence to topical medication (5% benzoyl peroxide gel: 71% vs 57.9%, p= 0.031; 0.05% tretinoin cream: 58.7% vs 45.4%, p= 0.044) at week 12. However, the intervention program did not improve adherence to oral medication. Overall, with intervention, a significantly higher percentage of improvement in disease severity was noted (47.3% vs. 39.1%, p=0.044). Nonadherence to treatment was attributed mostly to forgetfulness in 54% of the patients, followed by a busy lifestyle (41%) and little knowledge of acne (26%).

    CONCLUSION: Patients have significantly better adherence to topical medication with education and counselling. Better adherence to treatment leads to more remarkable disease improvement.

    INTRODUCTION: Allergic rhinitis (AR) is an inflammatory disease of the nasal mucosa. It is among the most common diseases globally and usually persists throughout life. Allergic Rhinitis and Its Impact on Asthma (ARIA) is a wellestablished guideline applicable to AR and was updated regularly since 2001, aiming to improve the care for AR patients. We proposed a new questionnaire that addresses the severity of allergic rhinitis symptoms, specifically nasal symptoms, and its impact on quality of life in terms of specific vital activities such as sleeping, working, school performance, leisure, or sport, based on the ARIA guideline. The objective was to develop, validate and evaluate Allergic Rhinitis Symptoms and Impact Assessment (ARSIA) questionnaire among allergic rhinitis patients in Hospital Sultan Abdul Halim, Sungai Petani (HSAH), and Hospital Universiti Sains Malaysia (HUSM).

    MATERIALS AND METHODS: This is a prospective observational study to develop, validate and evaluate the ARSIA questionnaire based on ARIA guidelines. The sample will be obtained from the list of patients under follow-up in the ORL clinic HSAH and HUSM with ages of 18 to 60 years, patients clinically diagnosed with allergic rhinitis, and with positive skin prick test.

    RESULTS: A total of 150 patients with a positive skin prick test participated in this study. In the 'nasal symptom' and 'impact on daily activities' domains, calculated Cronbach's alpha shows a value of 0.878 and 0.811 respectively. The inter-item correlation was calculated to analyse internal consistency reliability. Items B3 and B4 were dropped from the questionnaire as both showed a low correlation with other items. New Cronbach's alpha for the daily activities domain was 0.830, which showed better internal consistency reliability. All of the items were analysed for sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). Clinician diagnosis from the proforma was used as a comparison to the participant's responses. In the analysis, a cut-off points of 12 was used to classify the patient's nasal symptoms into intermittent or persistent, with a sensitivity of 75%, specificity of 86%, PPV of 95%, and NPV of 51%. Whereas, a cut-off point of 15 was used to classify the rhinitis impact on daily activities into mild or moderate/severe, with a sensitivity of 58%, specificity of 100%, PPV of 100%, and NPV of 42%. The only item in the 'control' domain has been dropped out following a consensus of experts and judgement as it has not been used in the clinician diagnosis and thus, is unable to test for sensitivity, specificity, PPV, and NPV.

    CONCLUSION: This newly developed, validated, and evaluated questionnaire is a good tool for the evaluation of allergic rhinitis symptoms and their impact on daily activities. It is important to understand that AR symptoms could have a significant impact on daily activities. Although further study and testing are needed, it provides an initial means for evaluating the patient condition and control level, as well as patients' perception of their rhinitis control.

    Haemophilia B is caused by coagulation defects in the factor IX gene located in Xq27.1 on the X chromosome. Identification of mutations contributing to defective factor IX may be advantageous for precise carrier and prenatal diagnosis. We studied 16 patients from 11 families, consisting of 8 patients of the Malay ethnic group, of which 6 were siblings. Factor IX mutations have not been previously reported in the Malay ethnic group. The functional region of the factor IX gene was sequenced and mutations were identified in either the exon or intronic regions in 15 of the patients. One novel mutation, 6660_6664delTTCTT was identified in siblings with moderate form of haemophilia B. Mutations identified in our patients when linked with disease severity were similar to findings in other populations. In summary, this preliminary data will be used to build a Malaysian mutation database which would facilitate genetic counseling.

    In 2003, it was discovered that the entry receptor for the Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) is a protein called the angiotensin-converting enzyme 2 (ACE2). This protein is present in a number of cell types, including those from the respiratory tract. Soon after the emergence of SARS-CoV-2 that is responsible for the disease Covid-19, scientists found that ACE2 was also used by the new coronavirus to infect cells. This opened some interesting possibilities to explain the striking variation in risks of catching and dying from Covid-19. The best recognised of these are the much higher risk of serious illness in older than younger people, in men than women, and in those with pre-existing comorbidities such as hypertension and cardiovascular diseases. There are several ways in which the ACE2 protein might contribute to this variation. The most obvious would be if there is more ACE2, there would be more entry points for the virus to infect the cell, e.g. in older people or in men. However, the evidence for this is rather small, partly because it is not that easy to obtain representative healthy tissues. Alternatively, it could be related to ACE2 membership of a family of proteins that has one end of the protein anchored inside the cell while most of the protein protrudes from the outside of the cell which therefore can be shed when cleaved by proteases at the cell membrane. Herein we review current evidence and theories of ACE2 role on SARS-CoV-2 infectivity and Covid-19 severity.

    INTRODUCTION: To evaluate the association of Procalcitonin (PCT) with severity in Coronavirus disease 2019 (COVID-19), hospitalised patients and to test the hypothesis that it is an independent predictor of mortality.

    MATERIALS AND METHODS: This study was conducted at Chemical Pathology, Department of Pathology and Laboratory Medicine and Department of Medicine, Aga Khan University (AKU), Karachi Pakistan. Electronic medical records of all in-patients including both genders and all age groups with documented COVID-19 from March to August 2020 were reviewed and recorded on a pre-structured performa. The subjects were divided into two categories severe and non-severe COVID-19; and survivors and non-survivors. Between-group differences were tested using the Chi-square and Mann-Whitney's U-test. The receiver operating characteristic curve was plotted for serum PCT with severity and mortality. A binary logistic regression was used to identify variables independently associated with mortality. The data was analysed using SPSS.

    RESULTS: 336 patients were reviewed as declared COVID-19 positive during the study duration, and 136 were included in the final analysis including 101 males and 35 females. A statistically significant difference in PCT was found between severe and non-severe COVID-19 (p value=0.01); and survivors and nonsurvivors (p value<0.0001). PCT, older age and increased duration of hospital stay were revealed as variables independently associated with mortality. On ROC analysis, an AUC of 0.76 for mortality prediction was generated for PCT.

    CONCLUSION: Baseline serum PCT concentration is a promising predictor of mortality and severity in COVID-19 cases when considered in combination with clinical details and other laboratory tests.

    The coronavirus disease 2019 (COVID-19) pandemic is severe and has not shown any signs of warning up to today. Biotech companies around the world have raced to come up with an acceptable vaccine and recently two mRNA vaccines have received emergency usage authorisation from regulatory bodies in several countries. mRNA vaccines, which consist of a new and revolutionary technology have not been previously tested widely on humans. Medium- and long-term safety data are not available. While many experts seem to support the start of a mass vaccination campaign, others feel there are too many unknowns to embark on a mass vaccination campaign. Concerns include uncertainties about the long-term effects of foreign mRNA on human cellular physiology and the possibility of vaccine-enhanced disease severity, which may not be unlikely with the current disease presentation of COVID-19.

    BACKGROUND: Studies have shown that certain genes within the major histocompatibility complex predispose to systemic lupus erythematosus (SLE) and may influence clinical and autoantibody expression. Thus, we studied the frequency of HLA-DR, -DQA, -DQB and -DPB alleles in ethnic Malays with SLE to determine the role of these genes in determining disease susceptibility and their association with clinical and immunological manifestations.
    METHODS: Fifty-six Malay SLE patients were enrolled into the study. Demographic, clinical and immunological findings were obtained from medical records. HLA-DR, DQ and DP typing were done using modified PCR-RELP. Controls were from ethnically-matched healthy individuals.
    RESULTS: We found a strongly significant association of the DR2 and DQB1 *0501 and DQB1*0601 (pcorr = 0.03, rr = 3.83, pcorr = 0.0036, rr = 4.56 and pcorr = 0.0048 and rr = 6.0, respectively). There was also a weak increase of DQB1*0.201 and DPB1*0.0901 with a weak decrease of DQA1*0601 and DQB1*0503 and *0301 which were not significant after corrections for multiple comparisons were made. There was a significant positive association of DR2 and DQB1*0501 with renal involvement and DR8 with alopecia. A nonsignificant increase of DQB1*0503 in patients with photosensitivity was noted. Significant autoantibody associations were also found: DQB1*0601 with anti-Sm/RNP, DR2 with antiSSA (Ro)/SSB (La), and DR2, DQB1*0501 and *0601 with antibodies to ds DNA. There was no specific DR, DQ or DP associations with age of disease onset (below 30 years or those at or above 30 years).
    CONCLUSION: Our data suggests the role of the HLA class II genes in conferring SLE susceptibility and in clinical and autoantibody expression.

    Spinal Muscular Atrophy (SMA) is an autosomal recessive disease, which is characterized by degeneration of the anterior horn cells of the spinal cord. SMA is classified into 3 clinical subtypes, type I (severe), type II (intermediate), and type III (mild). Two genes, SMN1 and NAIP, have been identified as SMA-related genes. The SMN1 gene is now recognized as a responsible gene for the disease because it is deleted or mutated in most SMA patients. However, the role of the NAIP gene in SMA has not been fully clarified. To clarify the contribution of NAIP to the disease severity of SMA, we studied the relationship between NAIP-deletion and clinical phenotype in Malaysian patients. A total of 39 patients lacking SMN1 (12 type I, 19 type II, and 8 type III patients) were enrolled into this study. Seven out of 12 patients with type I SMA (approximately 60%) showed NAIP deletion. On the contrary, only 2 out of 20 type II patients and none of type III patients showed NAIP deletion. There was a statistically significant difference in NAIP-deletion frequency among the clinical subtypes (Fisher's exact probability test, p value = 0.014). In conclusion, according to our data that NAIP deletion was more frequent in type I SMA than in type II-III SMA, the NAIP gene may be a modifying factor for disease severity of SMA.

    The purpose of this study was to compare the serum interleukin (IL)-23 levels between rheumatoid arthritis (RA) patients and healthy controls and to determine the correlation of IL-23 levels with disease activity, joint damage and functional disability in RA. Serum samples were obtained from 45 patients with RA and 45 healthy controls. The enzyme-linked immunosorbent assay method was used for quantitative analysis of IL-23. All the RA patients were assessed for disease activity based on the 28-joint disease activity score, joint damage based on modified Sharp score, and functional ability using the Health Assessment Questionnaire-Disability Index. The mean serum IL-23 level was much higher among the RA patients (24.50 ± 13.98 pg/mL) compared to the controls (5.98 ± 3.40 pg/mL; p < 0.01). There was a significant positive relationship between IL-23 levels and disease activity and questionnaire scores (p = 0.003 and 0.020, respectively). On logistic regression analysis, IL-23 levels were significantly higher in patients with moderate to high disease activity (p = 0.008, odds ratio = 1.073, 95% confidence interval = 1.019-1.130) and patients with significant functional disability (p = 0.008, odds ratio = 1.085, 95% confidence interval = 1.021-1.153). RA patients have significantly higher levels of serum IL-23. The IL-23 levels correlate well with disease activity and functional disability but not with radiographic joint damage.

    OBJECTIVE:
    To assess whether serum levels of CC and CXC chemokines correlate with disease activity in patients with rheumatoid arthritis (RA), and to determine whether these effects predict clinical response.

    METHODS:
    Serum levels of the chemokines CC (CCL2, CCL5) and CXC (CXCL8, CXCL9, CXCL10) were quantified at baseline and after 12 weeks of treatment with disease-modifying antirheumatic drugs or biologic agents in 28 patients using flow cytometry. Serum from 40 healthy individuals was collected for comparison at baseline. Response to treatment was classified according to the European League Against Rheumatism (EULAR) response criteria. Remission of disease was defined as a Disease Activity Score < 2.6.

    RESULTS:
    The baseline serum concentrations of CC and CXC chemokines were significantly elevated in patients with active RA compared to healthy controls (p < 0.05) except for CCL2. Significant improvement in all disease activity measurements was observed after 12 weeks of treatment. Seventeen (60.7%) patients achieved good to moderate response based on the EULAR response criteria, and 5 (17.9%) patients achieved remission. The improvement in clinical activity in patients with RA was accompanied by a significant reduction in the serum concentration of CXCL9 and CXCL10 (p < 0.001). A significant reduction in the serum level of CXCL10 was also observed in the group that achieved EULAR response. Serum concentration of CCL5 remained significantly elevated in patients with RA (n = 5) who achieved remission compared to the healthy controls (p < 0.05).

    CONCLUSION:
    Serum concentration of CXCL9 and CXCL10 may serve as sensitive biomarkers for disease activity in patients with RA.
