연구목적 섬망은 뇌 기능의 일시적 장애로 전신 염증반응이 위험 요인으로 알려져 있다. 염증지표 중 하나인 호중구림프구비(neutrophil-lymphocyte ratio, NLR)가 섬망 환자에서 염증지표로 활용 가능할지 C반응 단백질(Creactive protein, CRP)과의 비교를 통해 탐색하였다. 방 법 일병원에서 1년간 섬망으로 협의진료한 환자의 의무기록을 후향적으로 검토하였다. 치료 방법에 따라 내과적 치료군과 수술적 치료군으로 나누어 입원시와 섬망시의 NLR과 CRP 값을 확인하였고, 반복측정 분산분석을 통해 이들 사이의 상호작용을 확인하였다. 결 과 검사 종류, 측정시기, 치료군간 유의한 상호작용을 보였다. CRP는 수술적 치료군에서는 입원시에 비해 섬망일 때 증가하였으나 내과적 치료군에서는 감소하였다. NLR은 두 군 모두에서 입원시와 섬망시에 유의한 차이를 보이지 않았다. 결 론 섬망환자에서 NLR은 일정하게 유지되었으나 CRP는 치료군 및 섬망 유무에 따라 변화하는 양상을 보였다. 이는 NLR이 섬망 환자의 염증지표로 CRP와 상호보완적으로 활용될 가능성을 시사한다.

The purpose of this study was to determine the association between serum uric acid, abdominal obesity, and waist circumference (WC) in Korean. A total of 208 healthy examinees were examined at Gimcheon Medical Center from July 2011 to December 2011. WC and body mass index (BMI) of subjects were measured as well as blood pressure, fasting blood sugar level, High Density Lipoprotein (HDL) and Low Density Lipoprotein (LDL) cholesterol, C-reactive protein (CRP), triglycerides, and serum uric acid (SUA). In both men (p<0.05) and women (p<0.01), BMI and SUA were significantly correlated with WC. In men, triglycerides (r=0.501, p<0.01) had a positive correlation with WC, and CRP (r=0.442, p<0.01) had a positive correlation with BMI. In women, triglycerides (r=0.470, p<0.01) and CRP (r=0.366, p<0.01) had a positive correlation with WC. Therefore, WC and SUA may be the most effective anthropometric indices of obesity for screening Korean population.

Purpose: The aim of this study was to evaluate the clinical significance of inflammatory biomarkers in acute infectious diarrhea among children. Methods: Clinical parameters including fever, bacterial and viral etiology based on stool culture and multiplex polymerase chain reaction, and nine biomarkers including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and leukocytes in blood and calprotectin, lactoferrin, myeloperoxidase, polymorphonuclear elastase, leukocytes, and occult blood in feces were evaluated in children who were hospitalized due to acute diarrhea without underlying disease. Results: A total of 62 patients were included. Among these patients, 33 had fever, 18 showed bacterial infections, and 40 patients were infected with 43 viruses. Of all the biomarkers, CRP was significantly correlated with fever (p<0.001). CRP, ESR, calprotectin, lactoferrin, myeloperoxidase, fecal leukocytes, and occult blood were significantly associated with infection with bacterial pathogens (p<0.001, p=0.04, p=0.03, p=0.003, p=0.02, p=0.03, p=0.002, respectively). The combination of CRP and fecal lactoferrin at their best cut-off values (13.7 mg/L and $22.8{\mu}g/mL$, respectively) yielded a sensitivity of 72.2%, and a specificity of 95.5% for bacterial etiology compared with their individual use. Conclusion: Blood CRP is a useful diagnostic marker for both fever and bacterial etiology in acute pediatric diarrhea. The combination of CRP and fecal lactoferrin yields better diagnostic capability for bacterial etiology than their use alone for acute diarrhea in children without underlying gastrointestinal disease.

Background: In rotator cuff repair, the long head of the biceps tendon (LHB) is commonly used as graft material. However, factors influencing LHB tear severity are poorly understood, and predicting grade II LHB tears is challenging. This study aimed to identify these factors preoperatively. Methods: The demographics, medical parameters, and pain severity of 750 patients who underwent arthroscopic surgery from January 2010 to February 2021 were evaluated to determine the factors associated with LHB tear severity and grade II tears. Both overall and large-to-massive rotator cuff tear (RCT) cohorts underwent ordinal and binary logistic regression analyses. Predictive accuracy for grade II LHB tears was determined using the area under the receiver operating characteristic curve (AUC). Results: In the overall cohort, high-sensitivity C-reactive protein (hs-CRP) >1 mg/L (P<0.001), subscapularis tear (P<0.001), hypothyroidism (P=0.031), and the tangent sign (P=0.003) were significantly associated with LHB tear severity, and hs-CRP>1 mg/L, subscapularis tear, and Patte retraction degree were significantly associated with grade II LHB tears (P<0.001). In the large-to-massive RCT cohort, hs-CRP>1 mg/L, hypertension, and age ≥50 years (P<0.05) were significantly associated with LHB tear severity, and hs-CRP>1 mg/L (P<0.001) and hypertension (P=0.026) were significantly associated with grade II LHB tears. In both cohorts, hs-CRP >1 mg/L demonstrated good predictive accuracy for grade II LHB tears (AUCs: 0.72 and 0.70). Conclusions: Serum hs-CRP >1 mg/L is associated with LHB tear severity and serves as a reliable predictor of grade II LHB tears, facilitating preoperative assessment of the LHB as potential graft material in arthroscopic rotator cuff repair. serves as a reliable predictor of grade II LHB tears, facilitating preoperative assessment of the LHB as potential graft material in arthroscopic rotator cuff repair. Level of evidence: III.

Objectives: The purpose of this study was to investigate the relationship between periodontal disease, number of remaining teeth with high-sensitivity C-Reactive protein in Korean adults aged 40 and older. Methods: The study used the Sixth Korea National Health and Nutrition Examination Survey (KNHANES VI-3), 2015. The study sample consisted of 3,883 aged 40 years or older who had completed the health survey and the health examination. Logistic regression analyses were performed to examine the odds ratios of high-sensitivity C-Reactive protein by periodontal disease and number of remaining teeth, adjusting for demographic characteristics, chronic diseases and oral health behavior-related variables. Results: When the demographic and chronic diseases were adjusted, the risk of high-sensitivity C-Reactive protein (hs-CRP) average 1.23 mg/L or higher was 1.36 times higher in patients with periodontal disease between the ages of 40 and 49, but it was not significant (OR=1.36; 95% CI=0.82-2.23). In addition, in the group of 0~23 remaining teeth aged 40~49 years, the risk of higher than the average 1.23 mg/L of high-sensitivity C-Reactive protein was 2.03 times higher (OR=2.03; 95% CI=1.10-3.74), and 1.49 times higher in 60~69 years (OR=1.07; 95% CI=1.04-2.76). Conclusions: This study found that periodontal disease and tooth loss in Korean adults aged 40 and older was significantly associated with high-sensitivity C-reactive protein.

Baicalin has antioxidant, anti-inflammatory and anti-diabetic properties. IL-6 is a primary proinflammatory cytokine that contributes to impaired insulin signaling in liver. This study was carried out to investigate whether baicalin improves IL-6-mediated insulin resistance in liver. Hepa-1c1c7 cells were pre-treated with 50 and 100 ${\mu}M$ baicalin in complete media for 1 h and then cultured in the presence or absence of IL-6 (20 ng/ml). These results demonstrated that baicalin restored IL-6-suppressed expression of insulin receptor substrate (IRS)-1 protein, downregulated IL-6-increased gene expression of C-reactive protein (CRP) and suppressor of cytokine signaling (SOCS)-3, and inhibited LPS-induced production of IL-6 in Hepa-1c1c7 cells. These findings indicate that baicalin may ameliorate hepatic insulin resistance via improvement of IL-6-mediated impaired insulin signaling in hepatocytes.

Objective : C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) are often utilized to evaluate for postoperative infection. Abnormal values may be detected after surgery even in case of non-infection because of muscle injury, transfusion, which disturbed prompt perioperative management. The purpose of this study was to evaluate and compare the perioperative CRP, ESR, and white blood cell (WBC) counts after spine surgery, which was proved to be non-infection. Methods : Twenty patients of lumbar open discectomy (LOD) and 20 patients of posterior lumbar interbody fusion (PLIF) were enrolled in this study. Preoperative and postoperative prophylactic antibiotics were administered routinely for 7 days. Blood samples were obtained one day before surgery and postoperative day (POD) 1, POD3, and POD7. Using repeated measures ANOVA, changes in effect measures over time and between groups over time were assessed. All data analysis was conducted using SAS v.9.1. Results : Changes in CRP, within treatment groups over time and between treatment groups over time were both statistically significant F(3,120)=5.05, p=0.003 and F(1,39)=7.46, p=0.01, respectively. Most dramatic changes were decreases in the LOD group on POD3 and POD7. Changes in ESR, within treatment groups over time and between treatment groups over time were also found to be statistically significant, F(3,120)=6.67, p=0.0003 and F(1,39)=3.99, p=0.01, respectively. Changes in WBC values also were be statistically significant within groups over time, F(3,120)=40.52, p<0.001, however, no significant difference was found in between groups WBC levels over time, F(1,39)=0.02, p=0.89. Conclusion : We found that, dramatic decrease of CRP was detected on POD3 and POD7 in LOD group of non-infection and dramatic increase of ESR on POD3 and POD7 in PLIF group of non-infection. We also assumed that CRP would be more effective and sensitive parameter especially in LOD than PLIF for early detection of infectious complications. Awareness of the typical pattern of CRP, ESR, and WBC may help to evaluate the early postoperative course.

Objectives: Epidemiological studies have reported that vitamin D deficiency is associated with inflammatory disease. Smoking is a well-known risk factor for inflammation. However, few studies have investigated the interactive effect of vitamin D deficiency and smoking on inflammation. This study aims to investigate the interaction of vitamin D and smoking with inflammatory markers in the urban elderly. Methods: We used data from the Korean Elderly Environmental Panel Study, which began in August 2008 and ended in August 2010, and included 560 Koreans ${\geq}60$ years old living in Seoul. Data was collected via questionnaires that included items about smoking status at the first visit. Vitamin D levels, high-sensitivity C-reactive protein (hs-CRP), and white blood cell (WBC) counts were repeatedly measured up to three times. Results: The association of vitamin D and hs-CRP was significant after adjusting for known confounders (${\beta}=-0.080$, p=0.041). After separate analysis by smoking status, the association of vitamin D deficiency and hs-CRP in smokers was stronger than that in nonsmokers (smokers: ${\beta}=-0.375$, p=0.013; non-smokers: ${\beta}=-0.060$, p=0.150). Smoking status was an effect modifier that changed the association between vitamin D deficiency and hs-CRP (interaction estimate: ${\beta}=-0.254$, p=0.032). Vitamin D was not significantly associated with WBC count (${\beta}=0.003$, p=0.805). Conclusions: Vitamin D deficiency was associated with hs-CRP in the urban elderly. Smoking status was an effect modifier of this association. Vitamin D deficiency was not significantly associated with WBC count.
