BACKGROUND/AIMS: Although erythrocyte sedimentation rate (ESR) is included as a laboratory parameter in Truelove and Witts' classification, C-reactive protein (CRP) is also used for severity assessment in ulcerative colitis (UC). Frequently, the discordance between ESR and CRP is observed in clinical practice. The aim of this study was to determine which parameter is more related with clinical activity in UC patients. METHODS: A total of 155 patients with UC were identified from January 2004 to March 2005. Their medical records were reviewed within these patients, a total of 541 assessments of disease activity were made. Correlation of clinical activity and laboratory tests were evaluated by Pearson's correlation coefficient. RESULTS: Pearson's correlation coefficients of ESR and CRP with clinical symptoms were 0.376 and 0.258, respectively. The correlation coefficient between ESR and CRP was 0.403 (p=0.000). A total of 131 (24.2%) assessments revealed discordance between ESR and CRP. When discordance occurred, the correlation coefficients with clinical symptoms were 0.338 for ESR (p=0.000) and 0.034 for CRP (p>0.01). Dividing discordant patients into high ESR/low CRP group and low ESR/high CRP group, the coefficients were 0.420 for ESR and 0.226 for CRP in high ESR/low CRP group, and 0.333 for ESR and 0.068 for CRP in low ESR/high CRP group. CONCLUSIONS: The correlation analysis indicates that ESR appears to be a more reliable laboratory parameter of disease activity than CRP in assessing the severity of UC. In particular, when the level of ESR and CRP is discordant, ESR is more useful in assessing the disease activity in UC patients.

BACKGROUND AND OBJECTIVES: Systemic activation of the inflammatory system after aortic injury may play a role in the development of complications. The aim of this study was to determine the significance of the inflammatory markers for the mortality of patients suffering with medically treated type B acute aortic syndrome (AAS). SUBJECTS AND METHODS: We analyzed a total of 81 patients who were admitted with AAS within 24 hours from the onset of the symptoms and who were medically treated between January 2000 and December 2004. The patients were divided into two groups: the moribund patients who died within 2 weeks (group I: n=8, mean age: 64.0+/-11.0 years) and the patients who survived over 2 weeks (group II: n=73, mean age: 62.6+/-13.7 years). The serum high-sensitivity C-reactive protein (hsCRP) levels, the white blood cell (WBC) and monocyte counts, and the plasma D-dimer levels were measured on admission. RESULTS: The baseline clinical characteristics were not different between the two groups. The major causes of in-hospital death in group I were extensions or rupture of type B dissection (6 cases) and acute renal failure (2 cases). The multivariate analysis demonstrated that a high monocyte count (>1,250/mm3), and high levels of hsCRP (>11 mg/dL) and D-dimer (>1.2 mg/dL) were independent determinants of the short-term mortality (OR=6.39, 6.14 and 9.00; 95% CI=1.19 to 34.1, 1.14 to 32.9 and 1.20 to 67.4; p=0.02, 0.04 and 0.03, respectively). CONCLUSION: Systemic activation of the inflammatory system in type B AAS patients may be one of the important factors associated with the development of short-term mortality.

BACKGROUND/AIMS: The aims of this study were to identify the value of inflammatory markers as pretreatment prognostic factors for patients with multiple myeloma (MM) and to estimate the value of a prognostic index including these markers at diagnosis. METHODS: A total of 273 newly diagnosed MM patients undergoing active treatment were analyzed in this study. The prognostic values for survival of the pretreatment inflammatory markers were investigated. A myeloma prognostic index (MPI) was derived using prognostic factors determined to be independently significant on multivariate analysis. RESULTS: A high pretreatment neutrophil-lymphocyte ratio (NLR), low platelet count, and high C-reactive protein (CRP) level had independently unfavorable significance for overall survival (OS). The MPI was derived based on these factors. Per the MPI, 1 point each was assigned to high NLR, low platelet count, and high CRP. Risk categories were stratified into low- (score 0), intermediate- (score 1), and high-risk (score 2 or 3) groups. The MPI demonstrated independent statistical significance for OS on multivariate analysis ([intermediate: hazard ratio (HR), 1.91; 95% confidence interval (CI), 1.12 to 3.24] and [high: HR, 3.37; 95% CI, 2.00 to 5.69]; p < 0.001). Moreover, this significance could be observed regardless of age, renal function, and exposure to novel agents. In addition, the International Staging System risk group could be further significantly stratified using the MPI. CONCLUSIONS: The MPI, consisting of pretreatment inflammatory markers, NLR, platelet count, and CRP, might be effective in predicting the survival of newly diagnosed MM patients undergoing active treatment.

BACKGROUND: There are conflicting data in the literature regarding aspirin resistance. This study evaluated the effect of biochemical aspirin resistance on initial stroke severity in acute stroke patients who had taken aspirin. METHODS: We reviewed acute ischemic stroke patients who were already on aspirin. Biochemical aspirin resistance was defined as an aspirin reaction unit score of > or =550, as evidenced by the VerifyNow-Aspirin assay, which was performed after 4 days of continuous aspirin medication. Initial stroke severity was evaluated using National Institutes of Health Stroke Scale (NIHSS) scores at day 4, which were dichotomized into mild (0-7) and severe (> or =8). Modified Rankin Scale scores were determined at 3 months. The Alberta Stroke Program Early CT Scores (ASPECTS) were assessed on initial diffusion-weighted imaging (DWI). We examined the relationships between biochemical aspirin resistance and initial stroke severity. RESULTS: Nine of 106 patients (8.5%) had biochemical aspirin resistance. The initial stroke severity was significantly associated with DWI-ASPECTS (p<0.001), initial C-reactive protein level (p=0.005), biochemical aspirin resistance (p=0.009), and stenosis or occlusion of the relevant artery (p=0.029). Multivariate analysis showed that biochemical aspirin resistance [odds ratio (OR), 15.24; 95% confidence interval (CI), 2.49-93.31; p=0.003] and initial C-reactive protein level (per 1 mg/dL; OR, 2.43; 95% CI, 1.47-4.00; p=0.001) were independently associated with initial stroke severity (NIHSS score > or =8). However, biochemical aspirin resistance was not associated with clinical outcome at 3 months (p=0.366). CONCLUSIONS: Biochemical aspirin resistance was independently associated with initial stroke severity. This suggests that detection of biochemical aspirin resistance in acute ischemic stroke is useful when choosing the optimal treatment.

Intestinal tuberculosis (ITB) remains prevalent in Asia. An interferon-γ assay (QuantiFERON-TB gold test [QFT]) is considered to be an effective supplementary tool for diagnosing ITB. We retrospectively analyzed the clinical features of ITB patients based on the initial results of QFT. A total of 109 patients with ITB were enrolled, and 82 patients (75.2%) showed positive QFT results. In the QFT-positive group, the mean age (44.1±12.0 years) was significantly higher than that in the QFT-negative group (37.0±14.8, p=0.0096). Abdominal pain (p=0.006) and diarrhea (p=0.030) were more frequent in the QFT-negative group. Further, C-reactive protein (CRP) levels were significantly higher in the QFT-negative group (6.4±9.9 mg/dL) than in the QFT-positive group (1.3±2.3, p<0.001). Multivariate analysis confirmed that younger age (p=0.016), diarrhea (p=0.042), and high levels of CRP (p=0.029) were independent predictors of QFT-negative results in patients with ITB. These results suggest that prior exposure to TB, reflected by QFT positivity, may cause mild inflammation in patients with ITB.

BACKGROUND AND OBJECTIVES: The differences in plaque characteristics between non-culprit lesions (NCL) in acute coronary syndrome (ACS) patients (ACS-NCL) and target lesions (TL) in stable angina (SA) patients (SA-TL) are not well understood. We used a virtual histology-intravascular ultrasound (VH-IVUS) to compare the plaque components between ACS-NCL and SA-TL. SUBJECTS AND METHODS: We compared VH-IVUS findings between 290 ACS-NCL and 276 SA-TL. VH-IVUS classified the color-coded tissue into four major components: green (fibrotic); yellow-green (fibro-fatty); white {dense calcium (DC)}; and red {necrotic core (NC)}. Thin-cap fibroatheroma (TCFA) was defined as a NC > or =10% of the plaque area in at least 3 consecutive frames without overlying fibrous tissue in the presence of > or =40% plaque burden. RESULTS: Although the plaque burden was significantly smaller (52+/-13% vs. 54+/-14%, p=0.044), ACS-NCL had a greater %NC area (17.9+/-11.6% vs. 14.3+/-8.7%, p<0.001) and %DC area (9.7+/-9.8% vs. 8.1+/-8.0%, p=0.032) compared with SA-TL at the minimum lumen site. By volumetric analysis, ACS-NCL had a greater %NC volume (15.8+/-9.2% vs. 13.9+/-7.4%, p=0.006) compared with SA-TL. TCFA was observed more frequently in ACS-NCL compared with SA-TL (27.6% vs. 18.1%, p=0.032). Independent predictors of TCFA by multivariate analysis were ACS {odds ratio (OR): 2.204, 95% CI: 1.321-3.434, p=0.021} and high-sensitivity C-reactive protein (OR: 1.101; 95% CI 1.058-1.204, p=0.035). CONCLUSION: Although the plaque burden was significantly smaller, ACL-NCL had more vulnerable plaque components compared with SA-TL, and ACS and high-sensitivity C-reactive protein were the independent predictors of TCFA.

PURPOSE: To investigate the possible associations of neutrophil-to-lymphocyte ratio (NLR) and high sensitivity C-reactive protein (hs-CRP) level with age-related macular degeneration (ARMD). METHODS: Patients were divided to three groups of 40 patients with non-neovascular ARMD (group 1), 40 patients with neovascular ARMD (group 2), and 40 healthy control subjects (group 3). The neutrophil and lymphocyte counts were evaluated using an ABX Pentra DF120/USA biochemical analyzer, and hs-CRP levels were measured using a Beckman Coulter Immage 800. The NLR was measured by dividing neutrophil count by lymphocyte count. RESULTS: The patients in group 2 were older and more often diabetic than the patients in groups 1 and 3 (p < 0.001 and p < 0.001, respectively). The NLR level was 1.65 ± 0.71 in group 1, 1.98 ± 0.84 in group 2, and 1.46 ± 0.44 in group 3. The hs-CRP value was 1.98 ± 0.251 mg/L in group 1, 3.242 ± 0.211 mg/L in group 2, and 1.145 ± 0.193 mg/L in group 3. Both NLR and hs-CRP values were significantly higher in group 2 compared to group 3 (p = 0.002 and p = 0.002, respectively). In multivariate analysis, NLR remained an independent predictor of neovascular ARMD (odds ratio, 3.882; 95% confidence interval, 1.574 to 9.576; p = 0.003) together with age (p < 0.001), diabetes mellitus (p = 0.041), and hs-CRP (p = 0.018). CONCLUSIONS: Our study suggests that increased NLR value is independently associated with neovascular ARMD.
