Introduction
Hypoadiponectinaemia is an important risk factor for non-alcoholic fatty liver disease (NAFLD). However, little is known about its role in the Chinese population. This study sought to assess the prevalence of NAFLD and its association with hypoadiponectinaemia in middle-aged and elderly Chinese.Material and methods
We conducted a population-based cross-sectional study in an urban Shanghai sample of 2201 participants age 50 years to 83 years (973 men, 1228 women). Hepatic ultrasonographic examination was performed for all participants. Serum adiponectin concentrations were measured by ELISA methods.Results
The prevalence of NAFLD was 19.8% (16.0% in men, 22.8% in women). Serum adiponectin levels were significantly higher in female than in male subjects (p < 0.001). Serum adiponectin levels were significantly lower in NAFLD subjects than those in control subjects (p < 0.001). The prevalence of NAFLD progressively increased with declining adiponectin levels (p for trend < 0.001). The participants in the lowest adiponectin quartile had a significantly increased risk for acquiring NAFLD (OR = 2.31, 95% CI 1.72-3.15) after adjustment for potential confounders.Conclusions
Population-based screening suggests that NAFLD is highly prevalent in middle-aged and elderly people in Shanghai, particularly among women. Serum adiponectin level is negatively associated with NAFLD independently of potential cofounders, indicating that hypoadiponectinaemia may contribute to the development of NAFLD. 相似文献2.

Background/Aims
Waist circumference (WC) is a risk factor for metabolic syndrome and is related to insulin resistance (IR) and nonalcoholic fatty liver disease (NAFLD). The purpose of this study was to determine the association between WC and IR and NAFLD in apparently healthy Korean adults.Methods
The volunteers included in this cross-sectional study comprised 9,159 adults (5,052 men, 4,107 women) who participated in a comprehensive health checkup program. IR was evaluated by the homeostasis model assessment of IR (HOMA-IR) and was considered to be present when the HOMA-IR score was >2. NAFLD was evaluated by ultrasound examination. Elevated alanine aminotransferase (ALT) was defined as >40 IU/L in men and >35 IU/L in women. Logistic regression was performed to determine the odds ratios (ORs) and 95% confidence intervals (95% CIs) for NAFLD, IR, and ALT according to categorized levels of WC.Results
NAFLD was found in 2,553 (27.9%) of the participants (82.6% men, 17.4% women), while IR and elevated ALT were found in 17.2% (68.1% men, 31.9% women) and 10% (83% men, 17% women), respectively. After adjusting for confounding factors, the prevalence of NAFLD, IR, and elevated ALT was significantly associated with increases in WC quartile: highest quartile for NAFLD in men, OR=15.539, 95% CI=12.687-19.033; highest quartile for NAFLD in women, OR=48.732, 95% CI=23.918-99.288 (P<0.001); and highest quartile for IR in men, OR=17.576, 95% CI=13.283-23.255; highest quartile for IR in women, OR=11.078, 95% CI=7.813-15.708 (P<0.001); highest quartile for elevated ALT in men, OR=7.952, 95% CI=6.046-10.459; and highest quartile for elevated ALT in women, OR=8.487, 95% CI=4.679-15.395 (P<0.001).Conclusions
WC contributes to IR and NAFLD in apparently healthy Korean adults, and thus may be an important factor in the development of IR and NAFLD. 相似文献3.

Background/Aims:
A low vitamin D level has been associated with metabolic syndrome and diabetes. However, an association between a low vitamin D level and nonalcoholic fatty liver disease (NAFLD) has not yet been definitively established. This study aimed to characterize the relationship between a vitamin D level and NAFLD in Korea.Methods:
A cross-sectional study involving 6,055 health check-up subjects was conducted. NAFLD was diagnosed on the basis of typical ultrasonographic findings and a history of alcohol consumption.Results:
The subjects were aged 51.7±10.3 years (mean±SD) and 54.7% were female. NAFLD showed a significant inverse correlation with the vitamin D level after adjusting for age and sex [odds ratio (OR)=0.85, 95% confidence interval (CI)=0.75–0.96]. The age- and sex-adjusted prevalence of NAFLD decreased steadily with increasing vitamin D level [OR=0.74, 95% CI=0.60–0.90, lowest quintile (≤14.4 ng/mL) vs highest quintile (≥28.9 ng/mL), p for trend <0.001]. Multivariate regression analysis after adjusting for other metabolic factors revealed that NAFLD showed a significant inverse correlation with both the vitamin D level (>20 ng/mL) [OR=0.86, 95% CI=0.75-0.99] and the quintiles of the vitamin D level in a dose-dependent manner (p for trend=0.001).Conclusions:
The serum level of vitamin D, even when within the normal range, was found to be inversely correlated with NAFLD in a dose-dependent manner. Vitamin D was found to be inversely correlated with NAFLD independent of known metabolic risk factors. These findings suggest that vitamin D exerts protective effects against NAFLD. 相似文献4.
Purpose
In this study, we aimed to evaluate whether nonalcoholic fatty liver disease (NAFLD) was associated with the presence and morphology of coronary atherosclerotic plaques shown by multidetector computed tomography (MDCT) in asymptomatic subjects without a history of cardiovascular disease.Materials and Methods
We retrospectively enrolled 772 consecutive South Korean individuals who had undergone both dualsource 64-slice MDCT coronary angiography and hepatic ultrasonography during general routine health evaluations. The MDCT studies were assessed for the presence, morphology (calcified, mixed, and non-calcified), and severity of coronary plaques.Results
Coronary atherosclerotic plaques were detected in 316 subjects (40.9%) by MDCT, and NAFLD was found in 346 subjects (44.8%) by hepatic ultrasonography. Subjects with NAFLD had higher prevalences of all types of atherosclerotic plaque and non-calcified, mixed, and calcified plaques than the subjects without NAFLD. However, the prevalence of significant stenosis did not differ between groups. After adjusting for age, smoking status, diabetes mellitus, hypertension, dyslipidemia, and metabolic syndrome, NAFLD remained a significant predictor for all types of coronary atherosclerotic plaque [odds ratio (OR): 1.48; 95% confidence interval (CI): 1.05-2.08; p=0.025] in binary logistic analysis, as well as for calcified plaques (OR: 1.70; 95% CI: 1.07-2.70; p=0.025) in multinomial regression analysis.Conclusion
Our study demonstrated that NAFLD was significantly associated with the presence and the calcified morphology of coronary atherosclerotic plaques detected by MDCT. Further prospective clinical studies are needed to clarify the exact physiopathologic role of NAFLD in coronary atherosclerosis. 相似文献5.
Purpose
We investigated how serum low-density lipoprotein (LDL) level is related to various isoforms of apolipoprotein (ApoE) polymorphism in association with obesity and metabolic syndrome.Materials and Methods
We gathered total 332 sample of postmenopausal Korean women and analyzed ApoE isoforms, serum lipid level including LDL, blood pressure, fasting glucose, and anthropometry. The relationship between ApoE isoforms and serum lipid level, metabolic syndrome, and obesity was investigated.Results
Six ApoE isoforms were found, ApoE2 [E2/2 (n=1), E2/3 (n=54), E2/4 (n=14)], ApoE3 (E3/3, n=200), ApoE4 [E3/4 (n=55), and E4/4 (n=8)]. The prevalence of metabolic syndrome and obesity showed higher ApoE3 isoform than that of other isoforms. In additon, ApoE3 isoform was related to higher serum LDL and total cholesterol level than to ApoE2 isoform. The odds ratio of having the highest LDL cholesterol quartile in ApoE3 with obesity, compared to ApoE2 without obesity, was 3.46 [95% confidence interval (CI); 1.07-11.14, p=0.037], and odds ratio of ApoE3 with metabolic syndrome compared to ApoE2 without metabolic syndrome was 5.06 (95% CI; 1.14-22.29, p=0.037). Serum LDL cholesterol was positively associated with obesity or metabolic syndrome in ApoE3 isoform.Conclusion
This study suggests that obesity or metabolic syndrome risk should be effectively managed in ApoE3 isomform groups to reduce serum LDL in postmenopausal Korean women. 相似文献6.

Purpose
As Korean society has become industrialized and westernized, the prevalence of diabetes has increased rapidly. Environmental factors, especially socio-economic status (SES), may account for the increased prevalence of diabetes. We evaluated the associations between the prevalence of diabetes and SES as reflected by household income and education level.Materials and Methods
This study was based on data obtained from the fifth Korea National Health and Nutrition Examination Survey, conducted in 2010-2012. Diabetes referred to a fasting plasma glucose ≥126 mg/dL in the absence of known diabetes, previous diagnosis of diabetes made by a physician, and/or current use of oral hypoglycemic agents or insulin.Results
Household income and education level were inversely associated with the prevalence of diabetes among individuals aged 30 years or older. These associations were more prominent in females aged 30-64 years. According to household income, the odds ratio (OR) [95% confidence interval (CI)] for the lowest quartile group versus the highest quartile group was 4.96 (2.87-8.58). According to education level, the OR (95% CI) for the lowest quartile group versus the highest quartile group was 8.02 (4.47-14.4).Conclusion
Public policies for the prevention and management of diabetes should be targeted toward people of lower SES, especially middle-aged females. 相似文献7.

Purpose
To assess the estimate prevalence and risk factors for age-related maculopathy (ARM) in Seoul, Korea.Patients and Methods
We examined 9,530 subjects with, 40 years of age or older between January 2006 and December 2006 in Seoul, Korea. Subjects underwent fundus photography, clinical examinations (including blood analyses), and completed detailed questionnaires. Fundus images were graded according to definitions from the Wisconsin Age-Related Maculopathy Grading System.Results
ARM was present in 235 subjects, corresponding to an estimate prevalence of 2.46%. Hepatitis B infection (positive status for HBsAg and HBcAb), serum triglyceride levels and high density lipoprotein levels remained as significant risk factors after age-adjustment. Multivariate analyses showed that the prevalence of ARM was significantly higher in older subjects [odds ratio (OR) 1.134; 95% CI 1.114-1.154] and those who were seropositive for hepatitis B surface antigen (OR 2.566; 95% CI 1.519-4.335).Conclusion
The estimated prevalence of ARM was 2.46%. Age and hepatitis B infection may increase the risk of ARM. 相似文献8.

Background/Aims
Transferrin and alpha-1 antitrypsin are reportedly associated with liver fibrosis. We evaluated the usefulness of serum transferrin and alpha-1 antitrypsin as new liver fibrosis markers in patients with chronic hepatitis B.Methods
The study included 293 patients with chronic hepatitis B who underwent a liver biopsy between October 2005 and June 2009, and who had no history of hepatocellular carcinoma. Serum markers and liver fibrosis stages were compared.Results
Univariate analysis revealed that age (P<0.001), serum platelet count (P<0.001), and serum alkaline phosphatase level (P=0.003) differed significantly between the patients with and without liver cirrhosis. Serum transferrin levels were significantly lower in advanced fibrosis than in mild fibrosis in both univariate analysis (P=0.002) and multivariate analysis (P=0.009). In addition, the serum transferrin level was significantly lower in cirrhotic patients than in noncirrhotic patients (P=0.020). However, the serum level of alpha-1 antitrypsin was not significantly associated with liver cirrhosis in patients with chronic hepatitis B.Conclusions
Serum transferrin could be promising serum marker for predicting advanced liver fibrosis in patients with chronic hepatitis B. 相似文献9.

OBJECTIVE:
The individual components of metabolic syndrome may be independent predictors of mortality in patients with liver disease. We aimed to evaluate the prevalence of metabolic syndrome and its related components in hepatitis C virus–infected patients who are not obese and do not have type 2 diabetes.METHODS:
This cross-sectional study included 125 patients infected with hepatitis C virus genotype 1. Metabolic syndrome was defined according to the International Diabetes Federation. Anthropometric data were measured according to standardized procedures. Bioimpedance analysis was performed on all patients.RESULTS:
Metabolic syndrome was diagnosed in 21.6% of patients. Of the subjects with metabolic syndrome, 59.3% had hypertension, 77.8% had insulin resistance, 85.2% were overweight, 48.1% had a high waist circumference, 85.2% had an increased body fat percentage, and 92.3% had an elevated waist:hip ratio. In the bivariate analysis, female sex (OR 2.58; 95% CI: 1.09–6.25), elevated gamma-glutamyl transferase (γGT) (OR 2.63; 95% CI: 1.04–7.29), elevated fasting glucose (OR 8.05; 95% CI: 3.17-21.32), low HDL cholesterol (OR 2.80; 95% CI: 1.07–7.16), hypertriglyceridemia (OR 7.91; 95% CI: 2.88–22.71), elevated waist circumference (OR 10.33; 95% CI: 3.72–30.67), overweight (OR 11.33; 95% CI: 3.97–41.07), and increased body fat percentage (OR 8.34; 95% CI: 2.94–30.08) were independent determinants of metabolic syndrome. Using the final multivariate regression model, similar results were observed for abdominal fat (OR 9.98; 95% CI: 2.63–44.41) and total body fat percentage (OR 8.73; 95% CI: 2.33–42.34). However, metabolic syndrome risk was also high for those with blood glucose ≥5.55 mmol/L or HDL cholesterol <0.9 mmol/L (OR 16.69; 95% CI: 4.64–76.35; OR 7.23; 95% CI: 1.86–32.63, respectively).CONCLUSION:
Metabolic syndrome is highly prevalent among hepatitis C virus–infected patients without type 2 diabetes or obesity. Metabolic syndrome was significantly associated with hypertension, insulin resistance, increased abdominal fat, and overweight. 相似文献10.
Background
Hepatitis viral infections are major health challenge leading to high morbidity and mortality worldwide.Objectives
Although the magnitude of hepatitis in Pakistan has been well documented, information regarding the prevalence of hepatitis C virus (HCV) infection in Faisalabad, Pakistan is scarce. The present retrospective study was undertaken to determine the epidemiology of HCV in Faisalabad, Pakistan.Methods
Between May, 2010 and December, 2012, medical records of 39780 subjects visiting sexually transmitted infections (STIs) clinic, district headquarter (DHQ) hospital, Faisalabad, Pakistan were reviewed. Regression analysis was used to determine independent risk factorsResults
HCV prevalence was 21.99%. With mean age of 49.5 ± 2.7 years (range 27–63 years), majority (67.15%) of the individuals were male. Marital status and low literacy rates were associated with HCV (P<0.05). Reference to the potential risk factors, the injection drug use was the major mode (72.77%) of infection transmission. Age (OR 1.5, 95% CI 1.2–1.9), male gender (OR 1.2, 95% CI 0.9–1.6) and injection use (OR 1.9, 95% CI 1.0–2.7) were significantly associated with HCV.Conclusions
Most important finding was higher HCV prevalence in Faisalabad region as compared to the previous assessments that demands an urgent need for preventive intervention strategies. 相似文献11.

Background
The prevalence and severity of chronic kidney disease (CKD) in primary care patients with diabetes or hypertension is unknown.Aim
To assess the prevalence and severity of CKD in patients with diabetes and hypertension; and identify whether age, sex, diabetes, and hypertension are associated with CKD.Design of study
Cross-sectional survey.Setting
Two Dutch primary health care centres (15 954 enlisted patients).Method
Patients, aged ≥25 years, with known diabetes type 2 (n = 471) or hypertension (n = 960), were selected on 1 October 2006. Initial screening uptake rates were assessed from the electronic patient records, and patients were invited when blood or urine measurements were missing. The presence of albuminuria was determined, glomerular filtration rate estimated, and clinical characteristics extracted.Results
Initial screening uptake rates were 93% and 69% for diabetes and hypertension, respectively, and increased to 97% (n = 455) and 87% (n = 836) after active invitation. The prevalence of CKD was 28% in diabetes and 21% in hypertension only. The presence of diabetes was independently associated with albuminuria (odds ratio [OR] 4.23; 95% confidence interval [CI] = 2.67 to 6.71), but not with decreased estimated GFR (eGFR) (OR 0.75; 95% CI = 0.54 to 1.04). Age showed the strongest association with decreased eGFR (OR 2.73; 95% CI = 2.02 to 3.70).Conclusion
In primary care, more than one-quarter of patients with diabetes and about one-fifth of patients with hypertension have CKD. The high prevalence justifies longitudinal follow-up in order to evaluate whether intensified cardiovascular risk management is beneficial in this primary care population. 相似文献12.

Background/Aims
Nonalcoholic fatty liver disease (NAFLD) has recently been found to be a novel component of metabolic syndrome (MS), which is one of the leading causes of chronic liver disease. The serum alanine aminotransferase (ALT) and γ-glutamyltransferase (GGT) levels are suggested to affect liver fat accumulation and insulin resistance. We assessed the associations of serum ALT and GGT concentrations within the reference ranges with MS and NAFLD.Methods
In total, 1,069 subjects enrolled at the health promotion center of Wonkwang University Hospital were divided into 4 groups according to serum ALT and GGT concentrations levels within the reference ranges. We performed biochemical tests, including liver function tests and lipid profiles, and diagnosed fatty liver by ultrasonography. Associations of ALT and GGT concentrationgrading within the reference range with fatty liver and/or MS were investigated.Results
The presence of MS, its components, and the number of metabolic abnormalities [except for high-density lipoprotein-cholesterol (HDL-C) and fasting blood glucose] increased with the ALT level, while the presence of MS, its components, and the number of metabolic abnormalities (except for HDL-C) increased with the GGT level. The odds ratios for fatty liver and MS increased with the ALT level (P<0.001 and P=0.049, respectively) and the GGT level (P=0.044 and P=0.039, respectively).Conclusions
Serum ALT and GGT concentrations within the reference ranges correlated with the incidence of NAFLD and MS in a dose-dependent manner. There associations need to be confirmed in large, prospective studies. 相似文献13.

Background/Aims
Patients with various chronic liver diseases frequently have increased body iron stores. Prohepcidin is an easily measurable precursor of hepcidin, which is a key regulator of iron homeostasis. This study investigated the serum prohepcidin levels in patients with various chronic liver diseases with various etiologies.Methods
Serum prohepcidin levels were measured in patients with chronic hepatitis C (CH-C) (n=28), nonalcoholic fatty liver disease (NAFLD) (n=24), and alcoholic liver disease (ALD) (n=22), and in healthy controls (n=25) using commercial ELISA. Serum interleukin 6 (IL-6) levels and blood iron indices were also measured.Results
The serum levels of both prohepcidin and IL-6 were significantly higher in CH-C patients than in healthy controls, and there was a positive correlation between the IL-6 and prohepcidin levels (r=0.505, p=0.020). The prohepcidin levels in ALD patients did not differ from those in controls, despite their significantly elevated IL-6 levels. There was a tendency for a negative correlation between serum prohepcidin levels and transferrin saturation in ALD patients (r=-0.420, p=0.051). Neither prohepcidin nor IL-6 was significantly elevated in the NAFLD group, despite the presence of elevated serum iron and ferritin levels.Conclusions
The role of prohepcidin may differ in different human liver diseases. In the setting of CH-C, both the serum prohepcidin and IL-6 levels were significantly elevated and were positively correlated with each other. 相似文献14.
Background
Oxygen saturation is a good marker for disease severity in emergency care. However, studies have not considered its use in identifying individuals infected with Plasmodium falciparum at risk of deaths.Objective
To investigate the prevalence and predictive value of hypoxaemia for deaths in under-5s with severe falciparum malaria infection.Methods
Oxygen saturation was prospectively measured alongside other indicators of disease severity in 369 under-5s admitted to a tertiary hospital in Nigeria. Participants were children in whom falciparum malaria parasitaemia was confirmed with blood film microscopy in the presence of any of the World Health Organization-defined life-threatening features for malaria.Results
Overall mortality rate was 8.1%. Of the 16 indicators of the disease severity assessed, hypoxaemia (OR=7.54; 95% CI=2.80, 20.29), co-morbidity with pneumonia (OR=19.27; 95% CI=2.87, 29.59), metabolic acidosis (OR=6.21; 95% CI=2.21, 17.47) and hypoglycaemia (OR=19.71; 95% CI=2.61, 25.47) were independent predictors of death. Cerebral malaria, male gender, wasting, hypokalaemia, hyponatriaemia, azotaemia and renal impairment were significantly associated with death in univariate analysis but not logistic regression model.Conclusions
Hypoxaemia predicts deaths in Nigerian children with severe malaria, irrespective of other features. Efforts should always be made to measure oxygen saturation as part of the treatments for severe malaria in children. 相似文献15.
Purpose
Blood mercury levels are associated with inflammation, and chronic low-grade inflammation is a cause of insulin resistance. This study aimed to investigate the association between serum mercury and insulin resistance.Materials and Methods
Subjects from the 2008-2010 Korean National Health and Nutrition Examination Survey were selected (n=29235) and the relevant data of 5388 subjects (2643 males and 2745 females) were analyzed cross-sectionally. Homeostasis Model Assessment for Insulin Resistance (HOMA-IR) was compared according to blood mercury quartiles, and the odds ratio (OR) of having the highest quartile of HOMA-IR according to blood mercury quartiles was calculated.Results
Blood mercury levels in men and women were 29.4 nmol/L and 20.5 nmol/L, respectively, and fasting blood sugar (FBS), insulin, and HOMA-IR were significantly correlated with blood mercury levels. The correlation was stronger in men than in women. In men, FBS and HOMA-IR showed step-wise increases as the quartiles of blood mercury increased; only HOMA-IR differed significantly in the third and fourth blood mercury quartiles, compared to the first quartile. In women, however, both FBS and HOMA-IR differed significantly in the third and fourth blood mercury quartiles, compared to the first quartile. Among men, the OR of being in the highest HOMA-IR quartile was greatest for the highest blood mercury quartile (OR=1.720, 95% CI; 1.172-2.526), compared with the lowest quartile.Conclusion
In this large population-based study, blood mercury levels were weakly correlated with HOMA-IR and may be a risk factor for insulin resistance in nondiabetic Koreans. 相似文献16.

Background/Aims
Abdominal ultrasonography is useful for the detection and diagnosis of nonalcoholic fatty liver disease (NAFLD). The aims of this study were to establish a predictive model for the selection of subjects for abdominal ultrasonography for the diagnosis of NAFLD and to assess validity of the model.Methods
The subjects included 901 people who visited the health examination center of the Busan Medical Center. We conducted multiple logistic regression analyses of potential risk factors to identify independent risk factors for NAFLD, and developed an index system.Results
Four independent risk factors were identified. The index system was developed by assigning 1 clinical scoring point to approximately 0.7 logistic regression coefficients to each factor as follows: alanine aminotransferase/aspartate aminotransferase ratio >1.5 (odds ratio [OR], 2.22; 95% confidence interval [CI], 1.21-4.07; P=0.010), 1 point; γ-glutamyl transpeptidase >50 (OR, 2.15; 95% CI, 1.13-4.07; P=0.019), 1 point; triglyceride >150 mg/dL (OR, 1.92; 95% CI, 1.14-3.24; P=0.015), 1 point; 23 kg/m2≤BMI<25 kg/m2 (OR, 3.68; 95% CI, 2.05-6.63; P<0.001), 2 points; and BMI 25 kg/m2 (OR, 7.65; 95% CI, 4.29-13.62; P<0.001), 3 points. The area under the receiver operating characteristics curve was 0.797 (95% CI, 0.751-0.842), and when 3 points was used as a cut-off value, the sensitivity and specificity were 71.7% and 75.9%, respectively.Conclusions
NAFLD can be predicted through the clinical application of the index system established herein. If abdominal ultrasonography is used for high-risk patients, NAFLD will be diagnosed and managed in its early stage. 相似文献17.

Background/Aims
The prevalence of nonalcoholic fatty liver disease (NAFLD) in Korea has increased recently. The aim of the present study was to determine the regional differences in the prevalence and characteristics of NAFLD.Methods
From January 2009 to December 2010, 161,891 Seoul and Gyeonggi-do residents receiving a health examination at our institution were enrolled in this cross-sectional study. After applying exclusion criteria, the data of 141,610 subjects (80,943 males, 60,667 females) were analyzed. The presence of NAFLD was established by ultrasound examination.Results
The overall prevalence of NAFLD was 27.3% (38.3% in men, 12.6% in women). When standardized according to age, area, and sex, the prevalence of NAFLD was 25.2%. The age and area standardized prevalence of NAFLD was higher for men (34.4%) than for women (12.2%; P<0.001). The overall prevalence of NAFLD was higher in Gyeonggi-do (27.7%) than in Seoul (26.9%; P<0.001). Among the men, the prevalence of NAFLD was higher in Gyeonggi-do (39.2%) than in Seoul (37.4%; P<0.001), while for the women it was higher in Seoul (13.2%) than in Gyeonggi-do (12.0%; P<0.001).Conclusions
The regional prevalence of NAFLD differed between Seoul and Gyeonggi-do. Further studies are needed to establish the etiology of this difference. 相似文献18.

Purpose
Cephalosporins can induce occupational allergies, such as asthma, urticaria, and anaphylaxis. We investigated the prevalence and risk factors of sensitization to cephalosporin.Methods
A total of 161 health care workers (HCW), including 138 nurses and 23 pharmacists, and 86 unexposed non-atopic healthy controls were recruited from a single tertiary hospital and the general population. A questionnaire regarding work-related symptoms was administered along with skin prick tests (SPT) to the three most commonly used cephalosporins (cefotiam, ceftriaxone, and ceftizoxime). Serum specific IgE antibodies to conjugates of the three cephalosporins and human serum albumin (HSA) were measured by enzyme-linked immunosorbent assay (ELISA). Binding specificities were confirmed by ELISA inhibition tests.Results
The prevalence of work-related symptoms in association with cephalosporins was 17.4%. The sensitization rate to any cephalosporin was 3.1% by SPT. Sensitization rates determined by measurement of serum specific IgE antibodies were 17.4% for any cephalosporin, 10.4% for cefotiam, 6.8% for ceftriaxone, and 3.7% for ceftizoxime. A personal history of any antibiotic allergy was a risk factor for work-related symptoms (OR, 24.93; 95% CI, 2.61-238), but not for the presence of serum specific IgE antibodies to cephalosporins (OR, 0.9; 95% CI, 0.18-4.53). A personal history of atopic dermatitis was a risk factor for the presence of serum specific IgE antibodies to cefotiam-HSA conjugate (OR, 6.30; 95% CI, 1.23-32.3).Conclusions
A high cephalosporin sensitization rate (17.4%) was detected by ELISA in HCW exposed to cephalosporins. Monitoring of serum specific IgEs to cephalosporin-HSA conjugates will be useful for detecting sensitized subjects. 相似文献20.
