Increased psoriasis frequency in patients with familial Mediterranean fever

Objective: Familial Mediterranean fever (FMF) is a periodic fever syndrome caused by MEFV mutations. FMF may be associated with psoriasis in some cases. The prevalence of psoriasis in the normal Turkish population is 0.42%. We aimed to investigate the prevalence of psoriasis among FMF patients and their relatives.

Methods: FMF patients followed at Hacettepe University Adult and Pediatric Rheumatology Departments between January and August 2016 were included. FMF patients/their relatives were accepted to have psoriasis if the diagnosis was made by a dermatologist.

Results: A total of 351 FMF patients (177 adults; 174 children) were included. The median (min–max) age of adult and pediatric patients was 35 (19–63) and 10 (2–18) years, respectively. Thirteen (3.7%) FMF patients (11 adults, 2 children) had psoriasis. Psoriasis was more common in adult than pediatric patients (p?=?0.02). Psoriasis was present in 22 (12.4%) of adult and 9 (5.2%) of pediatric patients’ relatives (p?=?0.023). The frequency of psoriasis in ≥1 relatives of FMF patients was found to be 8.8%. Abdominal pain and fever were significantly higher, and arthralgia, arthritis, pleural chest pain, and pericarditis were significantly less frequent in the pediatric group than in adults (p?<?0.05).

Conclusion: Psoriasis was more common in FMF patients than in the normal population. Thus, FMF patients should be questioned and carefully examined for psoriasis lesions and psoriasis family history. Prospective multicenter studies may be important to find the incidence of psoriasis in FMF.     

Association between Metabolic Syndrome and Carotid Atherosclerosis: A Cross-sectional Study in Northern China

ObjectiveIncreased carotid artery intima-media thickness (CIMT) and carotid plaque as manifestations of carotid atherosclerosis have been used as markers of cardiovascular disease (CVD). The components of metabolic syndrome (MetS) are linked to CVD, but the association between MetS and CVD is controversial.MethodsA total of 8,933 Chinese adults aged 40 years or older from 2010 to 2014 were selected from the Jidong and Kailuan communities. MetS was defined by the International Diabetes Federation criteria. CIMT and carotid plaque were measured using color Doppler ultrasound. Logistic regression models were used to assess the association of MetS with carotid plaque and CIMT.ResultsMetS was found among 3,461 (3,461/8,933) participants. The odds ratio and 95% confidence internal (CI) for carotid plaques in participants with MetS was 1.16 (1.03–1.30). The risk of carotid plaques increased with the number of MetS components. The average CIMT was higher in participants with MetS (β = 0.020, 95% CI, 0.014–0.027) and in participants with more MetS components.ConclusionIndividuals with MetS are at an increased risk for carotid atherosclerosis compared to those without MetS.     

Anxiety,depression and harmful use of alcohol in severe chronic plaque psoriasis: A cross-sectional study

BackgroundPsoriasis is a common, chronic T cell–mediated disease characterised by erythematous, scaly plaques. Psoriasis is associated with depression, anxiety, poor quality of life, harmful use of alcohol and suicidal ideation. We performed this study to find out prevalence of psychological morbidity in our patients with severe psoriasis and to know clinical variables associated with higher risk of psychological morbidity.MethodThis study is a cross-sectional, observational study conducted in a dermatology outpatient department (OPD) of a tertiary care centre. Study population included patients with severe psoriasis area severity index (PASI>10). Clinical and epidemiological data, Patient health questionnaire-9, Generalised anxiety disorder-7, Dermatology life quality index (DLQI) and Alcohol Use Disorders Identification Test questionnaires were recorded. Data were analysed using SPSS, version 24. Chi-square test and Spearman's rank correlation test (ρ) were performed, and p value of <0.05 was considered statistically significant.ResultA total of 140 patients were included in the study and consisted of 67 men and 73 women. The median age was 44 years, median duration of disease was 10 years and median PASI was 13.6. Scoring revealed moderate-to-severe depression in 69 (49.3%) patients, moderate-to-severe anxiety in 40 (28.6%), severe impairment in quality of life in 98 (70%), harmful use of alcohol in 23 (16.4%) and suicidal ideation in 11 (7.8%) patients. Young age, recent onset, higher PASI and facial involvement show significant association with depression, anxiety and poor quality of life.ConclusionScreening for psychological morbidity should be performed in patients with severe psoriasis especially younger patients with recent onset disease. Higher DLQI points to concomitant psychological morbidity and it should be performed in all the patients.     

An examination of the prevalence of IDF- and ATPIII-defined metabolic syndrome in an Irish screening population

Objectives  To investigate the prevalence of ATPIII- and IDF-defined metabolic syndrome (MetS) in an Irish screening population and to determine the calculated cardiovascular risk for each group. Design  A total of 1,716 subjects were enrolled over a 12-month period. Main outcomes  The ATPIII-defined prevalence of MetS in this population was 13.2%. Using IDF criteria, 21.4% of subjects were identified as having the MetS. Correlation between the two definitions was high; however, IDF criteria identified an additional 9.5% (n = 164) of the population as having MetS, which ATPIII criteria failed to recognise. Conclusion  We noted a higher prevalence of MetS in the studied population when defined by IDF criteria. However, those identified by IDF and not by ATPIII definition did not have a higher cardiovascular risk score by either Framingham or European Score than those without MetS. Thus, application of the ATPIII definition of MetS, may be the more practical.     

Diagnostic performance of waist-to-height ratio in identifying cardiovascular risk factors and metabolic syndrome among adult Saudis: A cross-sectional study

Objectives:To evaluate the diagnostic performance of waist to height ratio (WHtR) to screen for cardiovascular risk factors (CVRF) and metabolic syndrome (MetS) among Saudis.Methods:Between June 2013 and August 2014, a cross-sectional study of 3,063 adult Saudis of both genders from King Khalid Hospital, Riyadh, Saudi Arabia was conducted. Using the “WHO STEPwise Surveillance-Instrument V2.1”, which uses sequential steps including questionnaires and anthropometric and biochemical measurements of MetS and CVRF. Waist to height ratio validity in defining central obesity, MetS, and CVRF were tested using receiver operating characteristic curve (ROC), sensitivity, specificity, positive and negative predictive values, and accuracy. Using multivariate regression analyses for adjustment of confounders as age and gender were applied to compute adjusted odds ratios (aOR).Results:The diagnostic potential of WHtR was excellent for central obesity (area under the curve [AUC] = 0.98), and MetS (AUCs = 0.86); it was good for CVRF ≥2 (AUCs = 0.79) and was satisfactory for dyslipidemia (AUCs = 0.66). The sensitivities and negative predictive values exceeded 85% for diagnosing central obesity, diabetes, and hypertension. Adjusted odds ratios for age and gender showed that WHtR ≥0.50 significantly increased the risk of diabetes, hypertension, and ≥2 CVRF by almost 4-fold, and increased the risk of dyslipidemia by 2-fold.Conclusion:Waist height ratio showed a good diagnostic performance for CVRF and MetS among Saudis. Furthermore, WHtR ≥0.5 increased the risk of dyslipidemia, diabetes mellitus and hypertension.     

Changes in the prevalence of comorbidity of mental and physical disorders in Singapore between 2010 and 2016

INTRODUCTIONFew studies have examined the changes in the prevalence of comorbidity of mental and physical disorders in recent years. The present study sought to examine whether the prevalence of comorbidity of mental and physical disorders in Singapore showed any changes between 2010 and 2016.METHODSWe extracted data from two repeated nationally representative cross-sectional surveys conducted among resident adults aged ≥ 18 years in Singapore. Significant changes were tested using pooled multinomial logistic regression analyses.RESULTSThe prevalence of comorbid mental and physical disorders increased significantly from 5.8% in 2010 to 6.7% in 2016. Among those with physical disorders, there were significant increases over time in the prevalence of comorbid generalised anxiety disorder (GAD) (0.1% vs. 0.4%) and obsessive-compulsive disorder (OCD) (1.4% vs. 3.9%) in diabetes mellitus, and alcohol dependence in cardiovascular disorders (0.1% vs. 1.3%). Among those with mental disorders, there were significant increases over time in the prevalence of comorbid diabetes mellitus in OCD (4.1% vs. 10.9%), cancer in major depressive disorder (0.4% vs. 2.4%), and cardiovascular disorders in GAD (0.4% vs. 6.7%) and alcohol dependence (0.9% vs. 11.8%). Significant changes in the overall prevalence of comorbid mental and physical disorders were also observed across age group, education and employment status.CONCLUSIONThe prevalence of comorbid mental and physical disorders increased significantly over time. This finding supports the need for more appropriate clinical management with better integration between mental health and general medical care professionals across all aspects of the healthcare system to treat this comorbidity in Singapore.

Metabolic syndrome defined by new criteria in Japanese is associated with increased liver enzymes and C-reactive protein

Metabolic syndrome (MetS) is characterized by the presence of atherogenic risk factors, and is associated with a marked increase in the risk of cardiovascular disease. Recently, the criteria of MetS were newly defined in Japan. We examined the relationship between MetS and the various metabolic parameters in Japanese subjects. This study included 458 Japanese subjects undergoing medical checkups at Nagoya University Hospital. New criteria developed by the joint committee of eight Japanese medical societies for the clinical recognition of MetS were adopted. We examined the association between MetS and various metabolic parameters, including liver enzymes (alanine aminotransferase, ALT; gamma glutamyltransferase, GGT) and highly sensitive C-reactive protein (hsCRP). The mean overall prevalence of MetS was 8.7% (male: 12.9%; female: 2.2%, p = 0.0001). MetS was significantly associated with elevated ALT (> 45 IU/L) (OR: 3.37, 95% CI: 1.19-9.52, p < 0.05) and GGT (> 64 IU/L in males, > 45 IU/L in females) (OR: 4.96, 95% CI: 2.31-10.66, p = 0.0001), respectively. MetS was also significantly associated with elevated hsCRP (> or = 0.1 ng/mL) (OR: 2.77, 95% CI: 1.20-6.41, p < 0.05). Thus, MetS was associated with elevated liver enzymes (especially, GGT), and inflammation (hsCRP).     

Prevalence of the metabolic syndrome in patients with diabetes mellitus

Background  Metabolic syndrome (MetS) is a vascular risk factor with prevalence in the general population of 17–25%. Aim  To determine the prevalence of MetS in patients with diabetes mellitus (DM). Methods  A total of 200 patients [18% type 1 (T1DM), 82% type 2 (T2DM)] attending for annual review were studied. Standard blood tests were requested. Blood pressure and waist circumference were measured. Adult Treatment Panel III (ATP III) criteria for diagnosis of MetS were applied. Results  A total of 122 (61%) patients had MetS. More patients with T2DM (69.5%) than TIDM (22.2%) had MetS. Despite treatment of DM (100%), hypertension (69.5%) and dyslipidaemia (48.3%), 114 patients (57%) still met the criteria for MetS at time of study. Conclusions  Most T2DM patients have MetS but it is uncommon in T1DM. Despite treatment, almost half of patients still met the criteria for MetS. Aggressive treatment of MetS components is required to reduce cardiovascular risk in DM.     

Effects of secukinumab and adalimumab on serum uric acid level in patients with plaque psoriasis

Background:Psoriasis is a chronic systemic inflammatory disease, and hyperuricemia is a common comorbidity in patients with psoriasis. However, there are limited reports on the relationship between serum uric acid levels and biological treatment efficacy. The purposes of this study were to compare the differences in serum uric acid levels between patients with psoriasis and healthy controls and analyze the risk of hyperuricemia.Methods:A total of 196 patients with psoriasis and 191 age- and sex-matched healthy controls were enrolled in this retrospective cohort study. One hundred and twenty-seven patients with severe psoriasis were treated with biologics. Sixty-eight patients received adalimumab, and 59 patients received secukinumab. Serum uric acid levels were measured at baseline, week 24, and week 48 of treatment.Results:Patients with psoriasis had higher serum uric acid levels than healthy controls (6.4 ± 1.7 mg/dL vs. 5.7 ± 1.5 mg/dL, P < 0.001). Hyperuricemia was found in 33.7% (66/196) of patients with psoriasis, which was significantly higher than that in healthy controls (13.1% [25/191], P < 0.001). Serum uric acid levels and hyperuricemia were not related to the severity of psoriasis (P > 0.05). No significant changes in serum uric acid levels and hyperuricemia were observed following adalimumab treatment (P > 0.05). The serum uric acid level in patients treated with secukinumab was 6.7 ± 1.6 mg/dL at week 24, which was not statistically different from that at baseline (6.6 ± 1.4 mg/dL, P = 0.885). Serum uric acid levels were significantly decreased at week 48 (6.3 ± 1.5 mg/dL vs. 6.6 ± 1.4 mg/dL, P = 0.007) in patients treated with secukinumab. Secukinumab had no significant effect on hyperuricemia either (P > 0.05).Conclusions:The serum uric acid levels and prevalence of hyperuricemia in patients with psoriasis were significantly higher than those in healthy controls. Secukinumab treatment for 48 weeks successfully decreased serum uric acid levels in patients with psoriasis, whereas adalimumab had no significant effect on serum uric acid levels.     

Association of Red Meat Usual Intake with Serum Ferritin and the Risk of Metabolic Syndrome in Chinese Adults: A Longitudinal Study from the China Health and Nutrition Survey

Objective The present study aimed to investigate the association of red meat usual intake with metabolic syndrome(Met S), and explore the contribution of red meat usual intake to serum ferritin.Methods Based on the data from the longitudinal China Health and Nutrition Survey(CHNS), 2,797 healthy adults aged 18–75 years without hypertension, diabetes, and Met S were selected in 2009 as subjects and follow-up studies were carried out till 2015. We used the National Cancer Institute(NCI)method to estimate the usual intake of foods. Multivariable logistic regressions were performed to evaluate the association between red meat usual intake and the risk of Met S. Quantile regression analysis was used to study the relationship between red meat consumption and serum ferritin levels.Results After adjusting for potential confounders, red meat, and fresh red meat were positively associated with the risk of Met S(RR = 1.41, 95% CI: 1.05–1.90 and RR = 1.37, 95% CI: 1.02–1.85,respectively). These relationships showed increasing trend(P 0.05). The level of serum ferritin increased significantly with the number of Met S components(P 0.05). The quantile regression analysis showed that red meat and fresh red meat usual intake had a significant positive association with serum ferritin levels across the entire conditional serum ferritin distribution(P 0.05). Processed red meat did not exhibit a similar association.Conclusion Higher red meat usual intake was associated with an increased risk of Met S and elevated serum ferritin levels.

Prognostic impact of stress echocardiography with discordant stress electrocardiography in patients with suspected coronary artery disease

INTRODUCTIONDuring stress echocardiography, the echocardiologist routinely collects both echocardiographic images and stress electrocardiogram (ECG) concurrently. The managing physician faces a dilemma when the stress ECG and stress echocardiography results are discordant; for example, when a patient has negative stress echocardiography but positive stress ECG. We therefore sought to evaluate the prognostic value of stress echocardiography in relation to concordant or discordant stress ECG findings in our local Singapore setting, which has a well-defined Southeast Asian population.METHODSThis was a retrospective observational study of all patients who underwent stress echocardiography in 2012 at Changi General Hospital, Singapore. All study patients were followed up for 18 months via electronic medical records.RESULTSThere was no difference in the major adverse cardiovascular events (MACE) outcome of patients with normal stress echocardiography and normal stress ECG (reference group) as compared with patients with normal stress echocardiography but positive (discordant) stress ECG (odds ratio 2.02, 95% confidence interval 0.82‑4.98; p = 0.125).CONCLUSIONThis study will help to reassure cardiologists that discordant results (negative stress echocardiography but positive stress ECG) do not portend a higher risk of MACE when compared to concordant results (i.e. both stress echocardiography and stress ECG are negative).     

银屑病住院患者1604例共患疾病临床分析

目的探讨银屑病及其共患疾病发病情况及影响因素。方法对上海市皮肤病医院2009年至2015年的1604例银屑病患者进行回顾性分析,比较银屑病与其共患疾病的相关性及影响因素。结果银屑病共患疾病主要有高血压、糖尿病、高脂血症、高尿酸血症、肝脏疾病（脂肪肝、肝炎、肝功能异常）、心血管疾病等。银屑病女性患者更易患心血管疾病(P＜0.05),男性更易患高脂血症、高尿酸血症(P＜0.05);从银屑病发病年龄看,有心血管病组较无心血管病组年龄大,糖尿病组较无糖尿病组大,高血压组较无高血压组大,高脂血症组较无高脂血症组大,高尿酸血症组较无高尿酸血症组大(P均＜0.05);有心血管病、高血压的患者银屑病平均病程长(P＜0.05);有吸烟史的银屑病患者更易罹患高脂血症(P＜0.05)。结论银屑病患者最易伴发血脂异常及肝脏疾病,其次为高血压、高尿酸血症、糖尿病,且性别、发病年龄、病程、家族史、吸烟史这5个因素可能是影响银屑病患者发生共患疾病的危险因素。     

Metabolic syndrome and C-reactive protein among cardiology patients

BACKGROUND: Associations between inflammation, metabolic syndrome (MetS), and cardiovascular disease have been reported. Limited information, however, is available on the prevalence of MetS and its relation to inflammation among Georgian cardiology patients. We investigated MetS components (elevated blood pressure, abdominal obesity, elevated triglyceride concentrations, decreased HDL-cholesterol concentrations, and elevated fasting glucose) and their relationships with C-reactive protein (CRP) concentrations in this population. METHODS: A total of 167 patients (mean age 53.1 years, 54% male) who attended an Emergency Cardiology Center in Tbilisi, Republic of Georgia were enrolled in this cross-sectional study. In-person interviews and clinical exams, as well as laboratory studies, were conducted to characterize MetS (using the ATP III criteria) and cardiac conditions in the study population. CRP concentrations were determined using standardized immunoassays. RESULTS: Overall prevalence of MetS was 40.7%. Patients with coronary heart disease (CHD) had higher CRP concentrations compared with non-CHD patients. A linear relationship between increase in number of MetS components and CRP concentrations was observed among females (p value for linear trend <0.05), but not males. Further, among females, all components of MetS except HDL-C concentrations were correlated with CRP concentrations after adjustment for age and body mass index (all p values <0.05). However, among males, only abdominal obesity was significantly correlated with CRP. CONCLUSIONS: MetS is prevalent among Georgian cardiology patients. CRP concentrations are positively associated with MetS. Further prospective studies are required to determine whether combining MetS and CRP data may have utility in the assessment of risk for developing future cardiovascular events in both males and females.     

Prevalence of hyperuricemia and its relationship with metabolic syndrome in Thai adults receiving annual health exams

BACKGROUND: Associations between hyperuricemia, metabolic syndrome, cardiovascular disease and diabetes have been reported. Limited information, however, is available concerning the prevalence and correlates of hyperuricemia among Thai men and women. We sought to estimate the prevalence of hyperuricemia among a population of patients receiving annual health exams and to evaluate its relationship with metabolic syndrome (MetS). METHODS: We conducted a cross-sectional study of 1,381 patients (376 men and 1,005 women) who first participated in annual health examinations at the Preventive Medicine Clinic of the King Chulalongkorn Memorial Hospital in Bangkok, Thailand during the period July 1999 through February 2000. Hyperuricemia was defined as >7.0 mg/dL in men and >6.0 mg/dL in women. MetS was defined using the modified ATP III criteria. RESULTS: The overall prevalence of the hyperuricemia was 10.6%. The condition was more common in men than in women (18.4 vs. 7.8%). Among women, serum uric acid was statistically significantly correlated with body mass index (BMI), systolic and diastolic blood pressure, high-density lipoprotein-cholesterol, triglyceride and fasting plasma glucose (all p <0.05). Men with serum uric acid concentrations >6.7 mg/dL (upper quartile) had a 3.91-fold increased in risk of MetS (95% CI:1.36-11.23), as compared with those who had concentrations <5.1 mg/dL (lowest quartile). Among women, the risk of MetS increased at least 2-fold for concentration of serum uric acid concentrations >4.0 mg/dL (p for trend <0.001). CONCLUSIONS: Hyperuricemia is prevalent among Thai men and women receiving routine health exams. Additionally, serum uric acid is positively associated with MetS.

Nailfold capillaroscopy in psoriasis

BackgroundPsoriasis a chronic inflammatory skin disease manifests with microcirculatory changes within skin which may precede skin manifestations, correlate with their severity, joint involvement and resolve with treatment. Nailfold capillaroscopy (NFC) is used in rheumatology for connective tissue disorder assessment and is assuming significance in psoriasis. The aim was to study the nailfold capillaroscopic findings in patients with psoriasis.MethodsA cross-sectional observational study was carried out at a skin center of a tertiary care hospital from January 2016 to June 2017. Selected cases underwent NFC using a portable color capillaroscope with an attached computer with software to analyze the nailfold capillaries for morphological parameters and abnormalities. Independent-samples t test and chi-square test was used to analyze the relationships between variables.ResultsMean capillary loop density in 96% of study population was subnormal (<9 capillaries/mm), mean arterial limb diameter 11.37 ± 2.434μ; mean venous limb diameter 15.89 ± 3.131μ, top of the loop diameter 14.41 ± 4.373μ and length of the loop was 152.51 ± 57.21μ. Only 3 had length of loop >300μ. Bizarre morphology was seen in 15.5% of capillaries (p value < 0.001). Crossed loops/tortuous capillaries were seen in 17.3% of patients (p value < 0.001). Ramified capillaries were seen in 9.1% of patients with psoriasis (p value < 0.001). Other abnormalities observed were hemorrhage, avascular areas and subpapillary plexus. Widespread disease and psoriatic arthritis (18.2%) had irregular and haphazard distribution of capillaries (p value < 0.001). Analysis of Psoriasis Area Severity Index score, age of the patient and NFC did not reveal any statistically significant relationship.ConclusionsNailfold capillaroscopy (NFC), a non invasive imaging technique for microcirculation evaluation can serve to prognosticate and follow up patirents with psoriasis as a simple and highly reproducible tool. Nailfold capillaroscopy is a simple and an easy method to study the microvascular abnormalities in psoriasis. Findings correlate with disease severity. It can be used for follow-up as a predictor of disease worsening or response to treatment.     

血浆微RNA-126表达水平对银屑病患者阿维A、甲氨蝶呤联合光疗应答的预测价值

目的 探索接受阿维A、甲氨蝶呤联合光疗治疗的银屑病患者血浆微RNA-126（miRNA-126）表达水平在治疗前后的变化及其对于疗效的预测作用。方法 连续纳入196例接受阿维A、甲氨蝶呤联合紫外线光疗治疗的中重度银屑病患者作为研究对象,并纳入同期200名健康志愿者作为对照。分别于基线期及治疗1个月、3个月和6个月后采集银屑病患者的血液样本,在入组后采集健康受试者的血液样本,测量血浆miRNA-126表达水平。采用银屑病皮损面积及严重度指数（PASI）评估疾病严重程度,PASI 50应答（治疗后PASI与基线期相比下降50%）和PASI 75应答（治疗后PASI与基线期相比下降75%）评估治疗效果。采用Spearman等级相关检验分析患者血浆miRNA-126表达水平与PASI的相关性,受试者工作特征（ROC）曲线评估miRNA-126相对表达量对银屑病的诊断价值,单因素和多因素logistic回归模型分析PASI 50和PASI 75应答的影响因素。结果 基线期银屑病患者血浆中miRNA-126呈低表达,其表达水平与患者PASI呈负相关（r=-0.222,P=0.002）。ROC曲线分析结果显示血浆miRNA-126表达水平可以较好地分辨银屑病患者与健康对照（曲线下面积为0.700）。治疗1个月、3个月和6个月后,银屑病患者血浆miRNA-126表达水平均比基线期增高（P<0.01）,PASI 50应答率分别为7.1%（14/196）、37.2%（73/196）及64.8%（127/196）,PASI 75应答率分别为1.5%（3/196）、14.3%（28/196）及35.7%（70/196）。PASI 50应答和PASI 75应答患者基线期血浆miRNA-126相对表达量高于未应答患者（P<0.05）。Logistic回归分析结果显示基线期血浆miRNA-126相对表达量与患者PASI 50应答和PASI 75应答独立负相关。结论 银屑病患者血浆miRNA-126表达水平在接受阿维A、甲氨蝶呤联合紫外线光疗治疗后逐渐升高,且其基线期表达水平与治疗效果独立负相关。     

Cholesterol goal achievement and lipid-lowering therapy in patients with stable or acute coronary heart disease in Singapore: results from the Dyslipidemia International Study II

INTRODUCTIONDyslipidaemia is a major risk factor for coronary heart disease (CHD). There is a lack of data on the extent of lipid abnormalities and lipid-lowering therapy (LLT) in Singapore.METHODSThe Dyslipidemia International Study (DYSIS) II was a multinational observational study of patients with stable CHD and hospitalised patients with an acute coronary syndrome (ACS). A full lipid profile and use of LLT were documented at baseline, and for the ACS cohort, at four months post-hospitalisation.RESULTS325 patients were recruited from four sites in Singapore; 199 had stable CHD and 126 were hospitalised with an ACS. At baseline, 96.5% of the CHD cohort and 66.4% of the ACS cohort were being treated with LLT. In both cohorts, low-density lipoprotein cholesterol (LDL-C) levels were lower for the treated than the non-treated patients; accordingly, a higher proportion of patients met the LDL-C goal of < 70 mg/dL (CHD: 28.1% vs. 0%, p = 0.10; ACS: 20.2% vs. 0%, p < 0.01). By the four-month follow-up, a higher proportion of the ACS patients that were originally not treated with LLT had met the LDL-C goal (from 0% to 54.5%), correlating with the increased use of medication. However, there was negligible improvement in the patients who were treated prior to the ACS.CONCLUSIONDyslipidaemia is a significant concern in Singapore, with few patients with stable or acute CHD meeting the recommended European Society of Cardiology/European Atherosclerosis Society goal. LLT was widely used but not optimised, indicating considerable scope for improved management of these very-high-risk patients.
