RESUMO

Aim: The authors investigated the association of red blood cell distribution width to albumin ratio (RAR) with prognosis and severity in acute ischemic stroke (AIS). Methods: One hundred twenty-seven patients with AIS were prospectively analyzed. The NIH Stroke Scale was used to determine stroke severity. RAR was compared between severe and nonsevere patients. Results: RAR was significantly higher in severe compared with nonsevere patients (p < 0.001). According to receiver operating characteristic analysis, RAR alone predicted mortality better than red blood cell distribution width and albumin (area under the curve: 0.933, 0.911, 0.870, respectively). Additionally, RAR was significantly correlated with NIH Stroke Scale score (p < 0.001). Conclusion: High RAR measured at presentation is a feasible index for prognosis and severity stratification in AIS.

RESUMO

OBJECTIVE: To investigate diagnostic value of ischemia-modified albumin (IMA) levels in patients applying to emergency with symptoms of acute coronary syndrome (ACS) and acute ischemic stroke (AIS). METHODS: Two patient groups (ACS and AIS) and a control group were constituted. The study was discontinued upon reaching 30 patients in each group. Following patient approval at the initial visit, a total of 10 ml venous blood sample was obtained from all patients with a high clinical suspicion of ACS and AIS. The Troponin I and the IMA levels were determined in the blood samples. RESULTS: Statistically significant higher IMA values were determined in the patient groups compared to the control group (p<0.001 for both groups). No statistically significant correlation was found between the IMA and the Troponin I values in the ACS and the AIS groups (p>0.05 for both groups). The sensitivity of IMA was 83% and 87% for ACS and AIS, respectively. The specificity of IMA was 90% and 87% for ACS and AIS, respectively. CONCLUSION: The sensitivity and specificity values, determined according to the optimal cut-off values in the groups demonstrated that IMA could be a useful diagnostic marker in ACS and AIS patients.

RESUMO

Purpose: The present study aimed to investigate the relationship between prognosis and the red cell distribution width (RDW) and the RDW-albumin ratio (RAR) in patients with coronavirus diseases 2019 (COVID-19), since serum albumin and RDW levels may reflect inflammatory conditions. Patients and Methods: A total of 289 patients who had been diagnosed with severe COVID-19 in the emergency department were retrospectively analyzed. The RAR levels were calculated by dividing RDW-CV by albumin. Patient groups (survivors, dying patients, those who received mechanical ventilation (MV) support or not, and those who needed vasopressors or not) were compared with regard to RDW-SD, RDW-CV and the RAR levels. Results: RDW-SD, RDW-CV and the RAR levels were found to be statistically significantly higher in patients who died, and who received MV and vasopressor support, compared to those who survived and did not receive support (p<0.001 for all). In addition, while the cut-off value of RAR was >5.43, the sensitivity was 91.6%, the specificity was 93.7%, NPV was 93.1% and the AUC was 0.965 in predicting mortality (p<0.001). Logistic regression analysis showed that RDW-SD and RAR were independent risk factors for mortality in patients with severe COVID-19. Conclusion: Elevated RDW and RAR levels at the time of admission may independently predict mortality and the need for vasopressor or MV support.

RESUMO

Aim: The study investigated heparin-binding protein (HBP) levels in patients with severe COVID-19 pneumonia and their relation to prognosis. Methods: A total of 134 patients with serious COVID-19 pneumonia were prospectively analyzed. HBP levels were statistically compared between both the patient and healthy control groups and within the patient group itself. Results: HBP was defined to be significantly higher in the patient group compared with the control group. There was a statistically significant distinction between the patients who survived and those who died with regard to HBP levels. When the cutoff value of HBP was >13.47, sensitivity (89.8%), specificity (74.1%) had area under the curve values of 0.806 (p < 0.001). Conclusion: HBP level may be used for prognosis prediction of patients with COVID-19.

RESUMO

Background/aim: Viral infections of the respiratory tract are generally related to many factors such as excessive production of cytokines, inflammation, cellular death, redox imbalance or oxidative stress. The aim of this study was to determine the serum levels of thiol and IMA in patients with severe COVID-19 pneumonia to evaluate oxidative stress. Study design: This was a prospective, sectional cohort study conducted at a pandemics hospital between 01.01.2022 and 01.02.2022. Methods: A total of 153 patients who had been confirmed with severe COVID-19 pneumonia in the emergency unit were prospectively analyzed. The control group was formed by 50 healthy volunteers with similar age and no chronic disease history. Thiol and IMA levels were statistically compared both in the patient and the control groups, and within the patient groups (survived and non-survival). Results: While 96 out of 153 patients had survived, 57 patients had non-survival. There was a statistically significant distinction between the survived and non-survival patients with regard to Thiol and IMA levels (p < 0.001). The thiol levels in the patient group were significantly lower compared to the control group, and the IMA levels were significantly higher (p < 0.001). The sensitivity, specificity and NPV were 70.2%, 86.5% and 83% when thiol cut-off value was ≤345.2 µmol/L (AUC: 0.886, p < 0.001). The sensitivity, specificity and NPV were 70.2%, 85.4% and 82.8% when the IMA cut-off was >302.9 ABSU (AUC: 0.875, p < 0.001). Conclusions: Our results demonstrate that thiol and IMA levels may be used as bioindicators for risk classification and mortality in patients with serious COVID-19 pneumonia.

RESUMO

The aim of this study is to investigate the routine blood parameters of COVID-19 patients at the time of admission to the emergency department and their relationship with the severity of the disease and prognosis. A total of 500 patients, who were diagnosed with severe COVID-19 and hospitalized in the intensive care unit between 01.04.2020 and 01.02.2021 in the emergency department of a pandemic hospital, were retrospectively analyzed. Demographic, clinical, and laboratory data of the patients were obtained from the hospital registry system. Neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR) were calculated using neutrophil, lymphocyte, monocyte, and platelet counts. These patients were divided into two groups: survivors and deceased. All parameters obtained from routine blood analysis were statistically compared between these two groups. While 280 out of 500 patients survived, 220 died. Of all patients, the mean age was 67 years and 51.8% were males. There was a significant difference between the two groups in terms of age, gender, length of hospital stay, need for mechanical ventilation, white blood cell, neutrophil, lymphocyte, monocyte, eosinophil, platelet counts, CRP, ferritin, procalcitonin values, NLR, MLR, and PLR (p < 0.001 for all). While NLR alone and MLR + NEU and NLR + PLR + MLR combinations had the highest AUC values (0.930, 0.947, and 0.939, respectively), MLR and PLR alone showed the lowest AUC values (0.875 and 0.797, respectively). The sensitivity, specificity, positive predictive values (PPVs), and negative predictive values (NPVs) in the prediction of death according to the cutoff values of the parameters have been determined. A significant correlation was determined between age, NLR, MLR, and PLR and duration of hospital stay (p < 0.001 for all). Routine blood parameters and NLR, MLR, and PLR can assist emergency physicians to identify the severity and early prognosis of COVID-19 patients.

RESUMO

BACKGROUND: Acute mesenteric ischemia (AMI) is associated with a high mortality rate, yet diagnostic difficulties persist. Although many biomarkers have been investigated for diagnostic purposes, as well as imaging methods, a sufficiently specific and sensitive marker has not been identified. This research was designed to examine whether heparin-binding protein (HBP), which has a role in the early phase of inflammation, could be useful in the diagnosis of AMI. METHODS: Serum samples obtained from a previously performed rabbit model of AMI were used in the study. HBP, C-reactive protein (CRP) and interleukin 6 (IL-6) levels were measured in blood samples obtained at baseline and 1, 3, and 6 hours from subjects that were separated into 3 groups: control, sham, and ischemia. The change in each marker over time and comparisons of the groups were evaluated statistically. RESULTS: A significant difference was not detected at the first hour in any of the studied markers. At the third hour, the CRP and IL-6 levels in the ischemia group indicated a significant increase in comparison with the control and sham groups (p<0.001). The HBP values showed a significant increase at the sixth hour in the ischemia group in comparison with the others (p<0.001). CONCLUSION: The HBP level demonstrated a slower increase in a rabbit model of AMI compared with CRP and IL-6. However, it still has the potential to become an early diagnostic biomarker. Diagnostic sensitivity and specificity should be evaluated in further clinical trials.

RESUMO

Acar T, Alkan G, Çaksen H, Ertekin B, Ergin M, Koçak S, Cander B. Phenytoin induced dystonia. Turk J Pediatr 2018; 60: 111-112. The abnormalities of dopaminergic activity in the basal ganglia have been emphasized to be effective in dystonia. We hereby report a case of a 2.5-year-old male patient who presented with tonic-clonic sezures and who developed dystonia after being given phenytoin. Biperidene hydrochloride was administered intramuscularly; primidone was added to the treatment regimen. After a 7-day-follow-up at the hospital, the patient had no dystonia and was discharged.

RESUMO

BACKGROUND: The study examined the Lp-PLA2 activity at the patients presented to the emergency department with acute coronary syndrome (ACS) or acute ischemic stroke (AIS), as well as its diagnostic value. METHODS: The prospective study included consecutive male and female patients aged >18 years that presented to the our emergency department with ACS or AIS between November 2009 and January 2010. Blood samples were obtained immediately following diagnosis in the ACS and AIS groups. The diagnostic value of Lp-PLA2 was determined based on receiver operating characteristic curves, sensitivity, specificity, predictive values, likelihood ratios and accuracy rates. RESULTS: In all, 34 ACS and 32 AIS patients were included in the study, and the control group included 35 patients. Lp-PLA2 enzyme activity was significantly lower in the ACS and AIS groups than in the control group (26.7 ± 13.8, 31.4 ± 13.6, and 41.4 ± 8.1 nmol min-1·mL-1, respectively; p < 0.0001, p = 0.022). In the ACS group the area under the curve (AUC) was 0.825 (95%CI: 0.722-0.929), sensitivity was 71% for an optimal Lp-PLA2 cut-off value of 31.4 nmol min-1·mL-1, and specificity was 91%, whereas in the AIS group the AUC was 0.768 (95%CI: 0.652-0.884), sensitivity was 75% for an optimal Lp-PLA2 cut-off value of 38.1 nmol min-1·mL-1, and specificity was 74%. CONCLUSIONS: Lp-PLA2 enzyme activity was significantly lower during the early stage of both ACS and AIS. The obtained statistic data suggest that low Lp-PLA2 enzyme activity can be used for diagnostic purposes.
