Abstract

The aim of the study was to assess plasma and scales levels of interleukin (IL) 18 collected from psoriatic patients with different disease activity. IL-18 concentrations were measured using an enzyme immunoassay in the plasma and scales of 34 patients with chronic plaque type psoriasis. IL-18 levels were analysed with respect to plasma-transforming growth factor β1 (TGF-β1), the disease duration and the duration of the present relapse, and psoriasis area and severity index (PASI). Plasma IL-18 concentration varied from 90 to 1300 pg ml?1 and means (368.2±42.4 pg ml?1) were significantly elevated in comparison with healthy controls (205.9±31.8 pg ml?1). The presence of IL-18 was also demonstrated in scales from skin lesions. Treatment caused a significant decrease of plasma IL-18 concentration to 250.2±13.8 pg ml?1. There was a significant correlation between plasma IL-18 levels and PASI values (r=0.554). There was no correlation between IL-18 concentration in scales and PASI, between IL-18 concentrations in plasma and scales, and between plasma IL-18 and the disease duration or duration of present relapse. Plasma TGF-β1 concentration demonstrated a significant correlation with PASI (r=0.353), but not with IL-18 levels in plasma (r=0.063) and scales (0.141). The sum of plasma levels of IL-18 and TGF-β1 divided by the optimal coefficient demonstrated a statistically significant correlation with the highest r-value. The findings confirm an association between plasma IL-18 concentration and psoriasis severity. Moreover, it was shown that combined measurement of IL-18 and TGF-β1 in plasma can be considered as a possible biomarker of psoriasis activity.  相似文献

ABSTRACT

Background: Jet-lag may affect air-travelers crossing at least two time-zones and has several health-care implications. It occurs when the human biological rhythms are out of synch with respect to the day-night cycle at the country destination. Its effect in psoriasis is missing. We aimed to evaluate the effect of Jet-lag in psoriatic patients’ management. Methods: This is a prospective observational study that enrolled psoriatic patients that underwent a flight: patients who experienced jet-lag were compared to patients who did not experience jet-lag. Before the flight, a dermatologist recorded clinical and demographical data with particular attention to Psoriasis Area Severity Index (PASI) and Disease Activity in Psoriatic Arthritis (DAPSA). Patients performed Self-Administered Psoriasis Area Severity Index (SAPASI), the Dermatology Life Quality Index (DLQI) and the pruritus Visual Analog Scale (VAS) scores. After the flight, patients completed the SAPASI, DLQI and pruritus-VAS scores. Results: The sample recruited comprised of 70 psoriatic patients aged 42.4 ± 9.7 years (median 42.5 years). Thirty (42.9%) were males, mean BMI was 25.5 ± 2.2 kg/m2. Average disease duration was 15.2 ± 7.1 years, and 20 (28.6%) subjects had developed PsA. Average hours of flight were 5.4 ± 3.5 (median 3.5 h), with 34 (48.6%) subjects reporting jet-lag. At the multivariate regression analysis, the change in the SAPASI score resulted correlated with jet-lag (regression coefficient 1.63, p = .0092), as well the change in the DLQI score (regression coefficient = 1.73, p = .0009), but no change on the pruritus VAS scale was found. Conclusions: The present study suggests that jet-lag may influence disease severity and DLQI scores, but not itch in psoriatic patients.  相似文献

Background

Red cell distribution width (RDW) is a routine laboratory measure associated with poor outcomes in adult critical illness.

Objective

We determined the utility of RDW as an early pragmatic biomarker for outcome in pediatric critical illness.

Methods

We used multivariable logistic regression to test the association of RDW on the first day of pediatric intensive care unit (PICU) admission with prolonged PICU length of stay (LOS) >48 hours and mortality. The area under the receiver operating characteristic curve (AUROC) for RDW was compared to the Pediatric Index of Mortality (PIM)-2 score.

Results

Over a 13-month period, 596 unique patients had RDW measured on the first day of PICU admission. Sepsis was an effect modifier for LOS >48 hours but not mortality. In sepsis, RDW was not associated with LOS >48 hours. For patients without sepsis, each 1% increase in RDW was associated with 1.17 (95% CI 1.06, 1.30) increased odds of LOS >48 hours. In all patients, RDW was independently associated with PICU mortality (OR 1.25, 95% CI 1.09, 1.43). The AUROC for RDW to predict LOS >48 hours and mortality was 0.61 (95% CI 0.56, 0.66) and 0.65 (95% CI 0.55, 0.75), respectively. Although the AUROC for mortality was comparable to PIM-2 (0.75, 95% CI 0.66, 0.83; p = 0.18), RDW did not increase the discriminative utility when added to PIM-2. Despite the moderate AUROC, RDW <13.4% (upper limit of lower quartile) had 53% risk of LOS >48 hours and 3.3% risk of mortality compared to patients with an RDW >15.7% (lower limit of upper quartile) who had 78% risk of LOS >48 hours and 12.9% risk of mortality (p<0.001 for both outcomes).

Conclusions

Elevated RDW was associated with outcome in pediatric critical illness and provided similar prognostic information as the more complex PIM-2 severity of illness score. Distinct RDW thresholds best discriminate low- versus high-risk patients.  相似文献

The aim of the study was to examine the influence of alcohol consumption on the severity of psoriasis and selenium (Se) concentration and Se-dependent gluathione peroxidase activity in plasma (pl-GSH-Px) and in erythrocytes (RBC-GSH-Px) in psoriatic patients. Thirty-five in-patients with psoriasis lasting <10 mo and 42 with psoriasis lasting >3 yr constituted groups 1 and 2, respectively. The severity of psoriasis was assessed using the PASI scoring system and the consumption of alcohol, using a structured questionnaire. The Se concentration was 47.11±11.61 μg/L in group 1 and 38.69±13.22 μg/L in group 2 (p<0.05), the pl-GSH-Px was 0.15±0.04 U/mL and 0.14±0.04 U/mL (p>0.05), and the RBC-GSH-Px was 13.97±4.27 U/g Hb and 13.16±3.85 U/g Hb (p>0.05), respectively. In excessive drinkers (<10% of patients, all males), the Se concentration was 32.84±10.88 μg/L, the pl-GSH-Px was 0.15±0.03 U/mL, and the RBC-GSH-Px was 11.64±3.32 U/g Hb. A low RBC-GSH-Px correlated to the consumption of high-grade alcoholic beverages (R=−0.45, p<0.05) and to the PASI value (R=−0.37, p<0.05) in group 2. Depressed Se concentration and Se-dependent GSH-Px can be related to the severity and a duration of psoriasis. The excessive consumption of alcohol is associated with severity of the disease and with low activity of GSH-Px in erythrocytes in patients with long-lasting psoriasis.  相似文献

Transforming growth factor-β1 (TGFβ1) is thought to be an inhibitor of the keratinocyte hyperproliferation associated with psoriasis. The aim of this study was to evaluate plasma TGFβ1 and TGFβ2 concentrations in psoriatic patients as possible indicators of treatment efficacy. TGFβ concentrations were measured in the plasma of 26 patients with psoriasis using an enzyme immunoassay and analysed with respect to the psoriasis area and severity index (PASI) before and after treatment with salicylic acid and/or sulphur followed by dithranol ointment. Baseline plasma concentrations of both TGFβ1 and TGFβ2 (20.3±2.2 ng ml?1 and 0.14±0.02 ng ml?1, respectively) did not differ significantly from control values (18.3±1.6 ng ml?1 and 0.14±0.03 ng ml?1, respectively). However, a significant positive correlation (r=0.69) between the baseline PASI and TGFβ1, but not TGFβ2, values was demonstrated. The pretreatment TGFβ1 concentration in patients with a PASI ≥15 (26.6±3.2 ng ml?1) was significantly higher than control values. There were no significant elevation of pretreatment TGFβ1 concentrations in patients with a PASI<15, or with respect to TGFβ2 in both groups. Treatment caused a significant decrease in TGFβ1, but only in patients with a PASI≥15. Patients with baseline TGFβ1 concentrations exceeding the mean of the control group had a PASI value that was significantly higher than that of patients with a TGFβ1 concentration below the mean of the controls. These results confirmed an association between plasma TGFβ1 concentration and psoriasis severity, and demonstrated its normalization during treatment. Measurement of TGFβ1 in plasma should be considered as a possible biomarker of psoriasis activity during its management.  相似文献

Vascular endothelial growth factor (VEGF) demonstrating pro-angiogenic activity promote new blood vessel formation in psoriatic lesions. The aim of this study was to evaluate the serum concentrations of VEGF, its soluble receptors (sVEGF R1 and R2) and VEGF content in scales of patients with psoriasis. To analyze possible association with activity of the disease, serum and scales from plaques were collected from 59 patients with exacerbated chronic plaque-type psoriasis. Mean concentrations of VEGF and sVEGF R1 in sera of patients were respectively two and four times higher than in healthy controls. Serum VEGF and sVEGF R1, but not sVEGF R2 demonstrated significant correlation with psoriasis area and severity index (PASI). There was also significant correlation between VEGF levels in serum and scales. Serum sVEGF R1 concentration was significantly elevated even in patients with low psoriasis activity (PASI < 10), whereas increase of serum VEGF became significant in patients with medium activity (PASI: 10–20). Levels of serum VEGF and sVEGF R1 were the highest in patients with PASI > 20. We confirmed association of both serum and scales VEGF concentrations with degree of psoriasis activity and demonstrated predominant increase of sVEGF R1 vs. VEGF in serum of patients with low psoriasis activity.  相似文献

Transforming growth factor-beta(1) (TGFbeta(1)) is thought to be an inhibitor of the keratinocyte hyperproliferation associated with psoriasis. The aim of this study was to evaluate plasma TGFbeta(1) and TGFbeta(2) concentrations in psoriatic patients as possible indicators of treatment efficacy. TGFbeta concentrations were measured in the plasma of 26 patients with psoriasis using an enzyme immunoassay and analysed with respect to the psoriasis area and severity index (PASI) before and after treatment with salicylic acid and/or sulphur followed by dithranol ointment. Baseline plasma concentrations of both TGFbeta(1) and TGFbeta(2) (20.3+/-2.2 ng ml(-1) and 0.14+/-0.02 ng ml(-1), respectively) did not differ significantly from control values (18.3+/-1.6 ng ml(-1) and 0.14+/-0.03 ng ml(-1), respectively). However, a significant positive correlation (r=0.69) between the baseline PASI and TGFbeta(1), but not TGFbeta(2), values was demonstrated. The pretreatment TGFbeta(1) concentration in patients with a PASI >/=15 (26.6+/-3.2 ng ml(-1)) was significantly higher than control values. There were no significant elevation of pretreatment TGFbeta(1) concentrations in patients with a PASI<15, or with respect to TGFbeta(2) in both groups. Treatment caused a significant decrease in TGFbeta(1), but only in patients with a PASI>/=15. Patients with baseline TGFbeta(1) concentrations exceeding the mean of the control group had a PASI value that was significantly higher than that of patients with a TGFbeta(1) concentration below the mean of the controls. These results confirmed an association between plasma TGFbeta(1) concentration and psoriasis severity, and demonstrated its normalization during treatment. Measurement of TGFbeta(1) in plasma should be considered as a possible biomarker of psoriasis activity during its management.  相似文献

BackgroundRed cell distribution width (RDW), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) are known inflammatory indices. Elevated values are found in many cancers and may be associated with a poor prognosis. The article aimed to assess the impact of RDW, NLR, and PLR on overall survival (OS) of patients with oropharyngeal cancer treated with radiotherapy (RT).Materials and methodsThis retrospective study includes 208 patients treated for oropharyngeal cancer with definitive RT or RT combined with neoadjuvant or concurrent systemic therapy, at one institution between 2004 and 2014. The receiver operating characteristic (ROC) method, log-rank testing, and Cox proportional hazards regression model were used for the analysis.ResultsThe OS was significantly higher in RDW ≤ 13.8% (p = 0.001) and NLR ≤ 2.099 (p = 0.016) groups. The RDW index was characterized by the highest discriminatory ability [area under the curve (AUC) = 0.59, 95% confidence interval (CI): 0.51–0.67], closely followed by NLR (AUC = 0.58, 95% CI: 0.50–0.65). In the univariate Cox regression analysis, RDW [hazard ratio (HR): 1.28, 95% CI: 1.12–1.47, p < 0.001] and NLR (HR: 1.11, 95% CI: 1.06–1.18, p < 0.001) were associated with an increased risk of death. In the multivariate analysis, among the analyzed indices, only NLR was significantly associated with survival (HR: 1.16, 95% CI: 1.03–1.29, p = 0.012).ConclusionsIn the study, only NLR proved to be an independent predictor of OS. However, its clinical value is limited due to the relatively low sensitivity and specificity.  相似文献

OBJECTIVE: To investigate expression patterns and relationship of vascular endothelial growth factor (VEGF), vascular endothelial receptor-3 (VEGF-R3) (FLT-4) and cyclooxygenase-2 (COX-2) in psoriasis. STUDY DESIGN: Forty-three patients were included in this study. The clinical severity of psoriasis was assessed using the psoriasis area and severity index (PASI). Punch biopsy samples both from psoriatic and nonlesional skin were taken and VEGF, VEGF-R3 and COX-2 expressions determined. RESULTS: VEGF, VEGF-R3 and COX-2 expressions were detected in 90.9%, 78.0% and 86.4% of psoriatic and 84.1%, 71.8%, and 84.1% of nonlesional skin, respectively. Epidermal VEGF, VEGF-R3 and COX-2 expressions were detected in 56.8%, 77.8% and 34.1 of psoriatic and 75%, 78.1% and 65.9% of nonlesional skin, respectively. In dermis, VEGF, VEGF-R3 and COX-2 expression was observed in 88.6%, 77.5% and 84.1% of psoriatic and 81.8%, 64.1% and 77.3% of nonlesional skin, respectively. Among the PASI subgroups no statistically significant differences were detected for VEGF, VEGF-R3 and COX-2 expression. CONCLUSION: Our study demonstrated that VEGF, VEGF-R3 and COX-2 expression in psoriatic and nonlesional skin is significantly high in epidermis and dermis. Although there was significant concordance between VEGF and VEGF-R3 expressions in psoriatic lesions, there seems to be no concordance between the others.  相似文献

Background

Red cell distribution width (RDW), one of many routinely examined parameters, shows the heterogeneity in erythrocyte size. We investigated the association of RDW levels with clinical parameters and prognosis of lung cancer patients.

Methods

Clinical and laboratory data from 332 patients with lung cancer in a single institution were retrospectively studied by univariate analysis. Kaplan-Meier survival analysis and Cox proportional hazard models were used to examine the effect of RDW on survival.

Results

The RDW levels were divided into two groups: high RDW (>=15%), n=73 vs. low RDW, n=259 (<15%). Univariate analysis showed that there were significant associations of high RDW values with cancer stage, performance status, presence of other disease, white blood cell count, hemoglobin, mean corpuscular volume, platelet count, albumin level, C-reactive protein level, and cytokeratin 19 fragment level. Kruskal-Wallis tests revealed an association of RDW values with cancer stage in patients irrespective of comorbidity (patient with/without comorbidity: p<0.0001, patient without comorbidity: p<0.0001). Stages I-IV lung cancer patients with higher RDW values had poorer prognoses than those with lower RDW values (Wilcoxon test: p=0.002). In particular, the survival rates of stage I and II patients (n=141) were lower in the high RDW group (n=19) than in the low RDW group (n=122) (Wilcoxon test: p<0.001). Moreover, multivariate analysis showed higher RDW is a significant prognostic factor (p=0.040).

Conclusion

RDW is associated with several factors that reflect inflammation and malnutrition in lung cancer patients. Moreover, high levels of RDW are associated with poor survival. RDW might be used as a new and convenient marker to determine a patient’s general condition and to predict the mortality risk of lung cancer patients.  相似文献

To identify diagnostic markers for psoriasis vulgaris and psoriatic arthritis, autoantibodies in sera from psoriasis vulgaris and psoriatic arthritis patients were screened by two-dimensional immunoblotting (2D-IB). Based on 2D-IB and MADLI TOF/TOF-MS analyses, eleven proteins each in psoriasis vulgaris and psoriatic arthritis were identified as autoantigens. Furthermore, serum levels of moesin, keratin 17 (K17), annexin A1 (ANXA1), and stress-induced phophoprotein-1 (STIP1), which were detected as autoantigens, were studied by dot blot analysis with psoriasis patients and healthy controls. The levels of moesin and STIP1 were significantly higher in sera from patients with psoriasis vulgaris than in the controls (moesin: P<0.05, STIP1: P<0.005). The area under the curve (AUC) for moesin and STIP1 between patients with psoraisis vulgaris and controls was 0.747 and 0.792, respectively. STIP1 and K17 levels were significantly higher in sera from patients with psoriatic arthritis than in those with psoriasis vulgaris (P<0.05 each). The AUC for STIP1 and K17 between patients with psoriatic arthritis and psoriasis vulgaris was 0.69 and 0.72, respectively. The STIP1 or moesin, CK17 serum level was not correlated with disease activity of psoriasis patients. These data suggest that STIP1 and moesin may be novel and differential sero-diagnostic markers for psoriasis vulgaris and psoriatic arthritis.  相似文献

Psoriasis is a chronic inflammatory skin disease, which has been linked to dyslipidemia with potential functional impairment of lipoproteins. This cross-sectional study was designed to characterize the biological activities of plasma lipoproteins in 25 patients with psoriasis and 25 age- and sex-matched healthy controls.In the present study, we found that plasma levels of high-density lipoprotein (HDL) cholesterol were decreased in the psoriasis group compared to healthy controls. The malondialdehyde (MDA) content in plasma, in HDL3 and in low-density lipoprotein (LDL) were increased. However, the activity of plasma paraoxonase-1 (PON-1) decreased in psoriasis and negatively correlated with the psoriasis area and severity index (PASI). Moreover, plasma levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were increased in psoriasis and positively correlated with the PASI. High-sensitivity C-reactive protein (hs-CRP) was increased in psoriasis, but did not reach significance when correlated with PASI. In vitro tests displayed that the functionalities of HDL3 isolated from psoriatic patients significantly decreased, which were assessed in four independent ways, namely (1) protection against LDL oxidation, (2) inhibition of tumor necrosis factor-α (TNF-α) induced monocyte adherence to endothelial cells, (3) prevention of oxidized low density lipoprotein (ox-LDL) induced monocyte migration, and (4) protection of endothelial cells from TNF-α induced apoptosis. Further, pro-oxidative and pro-inflammatory properties of LDL isolated from psoriatic patients were increased. In conclusion, the biological activities of psoriatic lipoproteins are impaired in both HDL and LDL, which may provide a link between psoriasis and cardiovascular disease.  相似文献

Global Registry of Acute Coronary Events (GRACE) risk score and red blood cell distribution width (RDW) content can both independently predict major adverse cardiac events (MACEs) in patients with acute coronary syndrome (ACS). We investigated the combined predictive value of RDW and GRACE risk score for cardiovascular events in patients with ACS undergoing percutaneous coronary intervention (PCI) for the first time. We enrolled 480 ACS patients. During a median follow-up time of 37.2 months, 70 (14.58%) patients experienced MACEs. Patients were divided into tertiles according to the baseline RDW content (11.30–12.90, 13.00–13.50, 13.60–16.40). GRACE score was positively correlated with RDW content. Multivariate Cox analysis showed that both GRACE score and RDW content were independent predictors of MACEs (hazard ratio 1.039; 95% confidence interval [CI] 1.024–1.055; p < 0.001; 1.699; 1.294–2.232; p < 0.001; respectively). Furthermore, Kaplan–Meier analysis demonstrated that the risk of MACEs increased with increasing RDW content (p < 0.001). For GRACE score alone, the area under the receiver operating characteristic (ROC) curve for MACEs was 0.749 (95% CI: 0.707–0.787). The area under the ROC curve for MACEs increased to 0.805 (0.766–0.839, p = 0.034) after adding RDW content. The incremental predictive value of combining RDW content and GRACE risk score was significantly improved, also shown by the net reclassification improvement (NRI = 0.352, p < 0.001) and integrated discrimination improvement (IDI = 0.023, p = 0.002). Combining the predictive value of RDW and GRACE risk score yielded a more accurate predictive value for long-term cardiovascular events in ACS patients who underwent PCI as compared to each measure alone.  相似文献

Abstract

The purpose of the study was to analyze the relationship between the serum concentration of soluble tumour necrosis factor-α type 1 (sTNF-R1), the severity of plaque-type psoriasis and therapeutic response. We compared sTNF-R1 in 25 patients treated with narrowband ultraviolet B (NB-UVB) radiation and 25 patients treated with systemic photochemotherapy (psoralen plus UVA – PUVA). The pretreatment Psoriasis Area and Severity Index (PASI) score and sTNF-R1 concentration were 16.32±5.26 and 1.99±0.40 ng ml?1, respectively, in the group treated with NB-UVB, and 17.22±3.48 and 2.07±0.31 ng ml?1, respectively, in the group treated with PUVA. The concentration of sTNF-R1 in healthy controls was 1.49±0.34 ng ml?1 (p<0.05 compared with patients with psoriasis). The pretreatment PASI score correlated with sTNF-R1 in both treatment groups (r=0.46 and r=0.44, p<0.05). NB-UVB and PUVA gave similar therapeutic effects (the PASI score after 20 treatments was 4.42±1.67 in the NB-UVB-treated group and 5.55±2.10 in PUVA-treated patients); however, the sTNF-R1 concentration at the same time differed significantly: 1.52±0.37 ng ml?1 and 1.98±0.39 ng ml?1 (p<0.001), respectively. Moreover, the decline in sTNF-R1 in both treatment groups was significant only in patients in whom the duration of skin lesions was less than 3 months. The results suggest that the value of serum sTNF-R1 concentration as a marker of response to phototherapy may depend on duration of skin lesions and the treatment method.  相似文献
