ABSTRACT

SUMMARY OBJECTIVES: This study aimed to investigate the ability of the biomarkers to predict the surgery treatment and mortality in patients above 18 years of age who were hospitalized with the diagnosis of bowel obstruction from the emergency department. METHODS: This is a 2-year retrospective study. The patients' demographic data, laboratory parameters on admission to emergency department, treatment modalities, and the length of hospital stay were recorded. Patients were divided into two groups: conservative and surgical treatment. Statistical analysis was performed to investigate the value of biomarkers in predicting mortality and the need for surgery. Data were analyzed using IBM SPSS version 22. RESULTS: A total of 179 patients were included in this study. Of these, 105 (58.7%) patients were treated conservative and 74 (41.3%) were treated operatively. The elevated procalcitonin (PCT) level, C-reactive protein, blood urea nitrogen-to-albumin ratio, and lactate-to-albumin ratio were significantly correlated with surgical treatment, length of hospital stay, and mortality. procalcitonin threshold value of 0.13 ng/mL was able to predict the need for surgical treatment, with a sensitivity of 79% and a specificity of 70.3%. Procalcitonin threshold value of 0.65 ng/mL was able to predict the mortality rate of the patients, with a sensitivity of 92.9% and a specificity of 78.1%. CONCLUSIONS: Biomarkers, especially procalcitonin, may be useful in bowel obstruction treatment management and may predict mortality.

ABSTRACT

SUMMARY OBJECTIVE: The aim of this study was to evaluate and compare C-reactive protein and C-reactive protein-to-albumin ratio performances in predicting mortality of geriatric patients who visited the emergency department. METHODS: The data of patients with COVID-19 and aged 65 years and above, who visited emergency department during the study period, were retrospectively analyzed. The data were obtained from an electronic-based hospital information system. The area under the receiver operating characteristic curve and the area under the curve were used to assess each cutoff value discriminatory for predicting mortality. RESULTS: The mean age of the population included in this study was 76 (71-82) years, while 52.7% were males. The sensitivity, specificity, and area under the curve values for C-reactive protein in terms of mortality were calculated as 71.01, 52.34, and 0.635%, respectively, while the sensitivity, specificity, and area under the curve values for C-reactive protein-to-albumin ratio were calculated as 75.74, 47.66, and 0.645%, respectively (p<0.001). In the pairwise comparison for the receiver operating characteristic curves of C-reactive protein and C-reactive protein-to-albumin ratio, no statistically significant difference was found. CONCLUSIONS: Geriatric patients are the "most vulnerable" patient group against the COVID-19. In this study, both C-reactive protein and C-reactive protein-to-albumin ratio were found to be successful in predicting mortality for geriatric COVID-19 patients.

ABSTRACT

Background: Anatomopathological staging is the primary method to determine the prognosis of patients with colorectal carcinoma (CRC). However, new tools have been developed that can complement it, such as the analysis of the elevation of systemic inflammatory markers. Objective: To evaluate the impact of the elevation of scores based on inflammatory markers (the neutrophil-to-lymphocyte ratio [NLR], the Glasgow Prognostic Score [GPS], and isolated C-reactive protein [CRP]) in the prognosis of patients diagnosed with CRC and submitted to potentially curative surgery in Hospital de Braga, Portugal, between January 1st, 2005, and December 31st, 2010. Methods: A retrospective analysis of the data of 426 patients was performed, with a collection of several clinico-pathological variables, as well as the levels of lymphocytes, neutrophils, albumin and CRP, in the pre- and postoperative periods, to apply the different scores to the sample. Results: From the analysis of the survival curves, we concluded that patients with increased NLR in the pre- and postoperative periods present a lower cancer-related survival than patients with normal NLR (preoperative period: 93.7 versus 122 months; p<0.001; postoperative period: 112 versus 131 months; p=0.002). Patients with increased NLR in the pre- and postoperative periods also had a lower disease-free survival (preoperative period: 88.0 versus 122 months; p<0.001; postoperative period: 111 versus 132 months; p=0.002). In addition, increased pre- and postoperative NLR was associatedwith a higher risk of death due to CRC (preoperatively: hazard ratio [HR]=2.25; p<0.001; postoperatively: HR=2.18; p=0.003). However, the multivariate analysis shows that only postoperative NLR (ajusted HR =2.66; p=0.002) does so independently of the remaining variables. Conclusion: Regarding the scores applied to the sample, the NLR was the one that most consistently related to the prognosis of the patients. However, it would be useful to develop a prospective study that could confirm this relationship. (AU)

ABSTRACT

Resumo Fundamento: A proteína C-reativa (PCR) é um biomarcador de inflamação preditor de eventos adversos em procedimentos cardiovasculares. Na avaliação do implante da válvula aórtica transcateter (transcatheter aortic valve implantation, TAVI) em relação ao prognóstico de longo prazo ainda é incipiente. Objetivo: Avaliar a PCR como marcador prognóstico no primeiro ano pós-TAVI na estenose aórtica (EAo). Métodos: A PCR foi avaliada na primeira semana do peroperatório numa coorte de casos retrospectiva com EAo. Correlacionou-se a PCR pré- e pós-TAVI com a mortalidade e foram pesquisados fatores preditores de mortalidade em 1 ano. Realizada regressão de Cox multivariada para identificar os preditores independentes de óbito em 1 ano. Resultados: Estudados 130 pacientes submetidos a TAVI, com mediana de idade de 83 anos, sendo 49% deles do sexo feminino. A PCR pré-TAVI elevada (> 0,5 mg/dL) ocorreu em 34,5% dos casos. O pico de PCR foi 7,0 (5,3-12,1) mg/dL no quarto dia. A mortalidade em 1 ano foi 14,5% (n = 19), sendo maior nos grupos com PCR pré-TAVI elevada (68,8% vs 29,1%; p = 0,004) e pico de PCR ≥ 10,0 mg/dL (64,7% vs 30,8%; p = 0,009). Os fatores preditores independentes de mortalidade foram insuficiência renal aguda (IRA) [razão de risco (RR) = 7,43; intervalo de confiança de 95% (IC95%), 2,1-24,7; p = 0,001], PCR pré-TAVI elevada [RR = 4,15; IC95%, 1,3-12,9; p=0,01] e hemotransfusão volumosa [HR = 4,68; 1,3-16,7; p = 0,02]. Conclusões: A PCR pré-TAVI elevada mostrou-se fator preditor independente de mortalidade no primeiro ano, assim como a ocorrência de IRA e hemotransfusões volumosas.


Abstract Background: C-reactive protein (CRP) is an inflammation biomarker that can be a predictor of adverse events in cardiovascular procedures. Its use in the assessment of long-term prognosis of transcatheter aortic valve implantation (TAVI) is still incipient. Objective: To evaluate CRP as a prognostic marker in the first year after TAVI in aortic stenosis (AoS). Methods: CRP was assessed on the first postoperative week in a retrospective cohort of patients with AoS. Pre- and post- CRP levels were correlated with mortality, and predictors of 1-year mortality were investigated. Multivariate Cox regression was performed to identify independent factors of 1-year mortality. Results: This study evaluated 130 patients who underwent TAVI, with median age of 83 years, and 49% of women. High pre-TAVI CRP (> 0.5 mg/dL) was observed in 34.5% of the cases. Peak CRP was 7.0 (5.3-12.1) mg/dL no quarto dia. The rate of 1-year mortality was 14.5% (n = 19), being greater in the groups with high pre-TAVI CRP (68.8% vs 29.1%; p = 0,004) and with peak CRP ≥ 10.0 mg/dL (64.7% vs 30.8%; p = 0,009). Independent predictors of mortality were acute renal failure (ARF) (hazard ratio [HR] = 7.43; 95% confidence interval [95%CI], 2.1-24.7; p = 0,001), high pre-TAVI CRP (HR 4.15; 95%CI, 1.3-12.9; p = 0.01), and large blood transfusion [HR 4,68; 1,3-16,7; p = 0.02]. Conclusions: High pre-TAVI CRP showed to be an independent predictor of 1-year mortality, as well as the presence of ARF and large blood transfusions.

ABSTRACT

Abstract Background: The pathophysiology of urticaria is still poorly understood. Recent studies demonstrate that the activation of coagulation is correlated with the clinical activity of Chronic Spontaneous Urticaria. Coagulation and inflammation are strongly linked. Objectives: To correlate the severity and activity of Chronic Spontaneous Urticaria with the levels of D-dimer, C-reactive protein, and autologous serum test in patients with Chronic Spontaneous Urticaria. Methods: The study included 55 patients diagnosed with chronic spontaneous urticaria. D-dimer levels were measured using enzyme-linked fluorescent assay and C-reactive protein levels were measured using the nephelometric method; autologous serum testing was performed on patients who discontinued antihistamine therapy. The severity of the disease was assessed using the urticaria activity score. Results: patients with severe, spontaneous, and difficult-to-control chronic urticaria had elevated serum levels of D-dimer, as well as a positive autologous serum test. Little correlation was demonstrated between the severity of chronic spontaneous urticaria and the levels of C-reactive protein. Conclusion: The authors concluded that patients with severe Chronic Spontaneous Urticaria showed signs of activated fibrinolysis. Most patients with high clinical scores had high D-dimer values. Patients with positive results for the autologous serum test also had more severe Chronic Spontaneous Urticaria and needed more drugs to control the disease. Finally, little correlation was found between C-reactive protein levels and disease severity. Study limitations: The main limitation was the small sample of patients. In the present patients, it was demonstrated that serum D-dimer levels and the autologous serum test can act as predictive markers of severity and activity of Chronic Spontaneous Urticaria.

ABSTRACT

INTRODUCCIÓN: El hipotiroidismo subclínico (HSC) se define bioquímicamente por una elevación en la concentración sérica de la hormona estimulante de la tiroides (TSH), con niveles normales de tiroxina libre (T4L). La asociación entre el HSC y el daño cardiovascular ha sido un tema controversial. OBJETIVO: determinar la asociación entre el HSC y el desarrollo de la enfermedad cardiovascular mediante la cuantificación de la proteína C reactiva ultrasensible PCR-us y la determinación de lípidos circulantes asociados a la enfermedad cardiovascular y la ateroesclerosis. MÉTODOS: Estudio descriptivo, correlacional de corte transversal realizado en el Hospital IESS de Riobamba, Ecuador en el periodo comprendido desde enero a diciembre de 2019. Se estudiaron 70 individuos (40 pacientes con HSC y 30 controles) con edades entre 18 y 75 años. Se realizaron las historias clínicas y el examen físico a cada paciente y la toma de las muestras sanguíneas para determinar la concentración sérica de los siguientes parámetros bioquímicos y hormonales: colesterol total, triglicéridos, HDL colesterol y LDL colesterol, TSH, T4L y PCR-us. RESULTADOS: Se encontró un incremento significativo en la concentración de colesterol total (p<0.0001), LDL colesterol (p<0.01) y PCR-us (p<0.0001) en los pacientes con HSC vs los controles. Se observó una correlación positiva (p<0.0001; r=0.9148) entre la TSH y la PCR-us en los pacientes con HSC. CONCLUSIÓN: los pacientes con HSC experimentan una elevación en los niveles séricos de PCR-us la cual está correlacionada con un incremento en la concentración sérica de TSH. Estos parámetros asociados a un aumento del colesterol total y de la LDL colesterol sugieren un estado inflamatorio de bajo grado que podría estar asociado con el desarrollo de aterosclerosis y daño cardiovascular.


INTRODUCTION: Subclinical hypothyroidism (SH) is defined biochemically by an elevation in serum thyroid stimulating hormone (TSH) concentration, with normal levels of free thyroxine (T4L). The association between SH and cardiovascular damage has been a controversial issue. OBJECTIVE: to determine the association between SH and the development of cardiovascular disease through the quantification of the high sensitivity C-reactive protein (hs-PCR) and the determination of circulating lipids associated to cardiovascular disease and atherosclerosis. METHODS: Observational, correlational cross-sectional study with patients captured in the internal medicine office as well as those attending screening activities at the IESS Hospital in Riobamba- Ecuador, in the period from January to December 2019. Seventy individuals (40 patients with SH and 30 controls) between the ages of 18 and 75 years were studied. Each patient's medical history and physical examination were performed, and blood samples were taken to determine the serum concentration of the following biochemical and hormonal parameters: total cholesterol, triglycerides, HDL cholesterol and LDL cholesterol, TSH, T4L and hs-PCR. RESULTS: A significant increase in the concentration of total cholesterol (p<0.0001), LDL cholesterol (p<0.01) and hs-PCR (p<0.0001) was found in patients with SH vs. controls. A positive correlation (p<0.0001; r=0.9148) was observed between TSH and hs-PCR in patients with SH. CONCLUSION: patients with SH experience an elevation in serum hs-PCR levels which is correlated with an increase in serum TSH concentration. These parameters associated with an increase in total cholesterol and LDL cholesterol suggest a low-grade inflammatory state that may be associated with the development of atherosclerosis and cardiovascular damage.

ABSTRACT

Resumen Introducción: La relación entre 25-OH-vitamina D y el sistema inmune en pacientes con enfermedad renal crónica es objeto de atención. Objetivos: Evaluar la prevalencia de la deficiencia de vitamina D en pacientes en hemodiálisis e investigar la asociación entre la vitamina D y proteína C reactiva ultrasensible (PCRus), índice neutrófilo/linfocito (INL) e índice plaqueta/linfocito (IPL). Método: Estudio transversal de 80 pacientes en hemodiálisis, divididos en dos grupos: un nivel sérico de 25-OH-vitamina D < 20 ng/mL se consideró como deficiencia de vitamina D y ≥ 20 ng/mL, como normal. Con el análisis de correlación de Spearman se definió la relación entre los parámetros. Resultados: 40 % de los pacientes presentó deficiencia de vitamina D. Hubo diferencias significativas entre los grupos en PCRus (p = 0.047), INL (p = 0.039), IPL (p = 0.042) y tratamiento con análogos de vitamina D (p = 0.022). La vitamina D tuvo una correlación negativa significativa con PCRus (p = 0.026), INL (p = 0.013) e IPL (p = 0.022). Conclusiones: La deficiencia de vitamina D fue de 40 %. Los niveles de PCRus, INL e IPL fueron significativamente más altos ante deficiencia de vitamina D. Se encontró correlación inversa significativa entre vitamina D y PCRus, INL e IPL.


Abstract Introduction: The relationship between 25-OH-vitamin D and the immune system in patients with chronic kidney disease is a subject of attention. Objectives: To assess the prevalence of vitamin D deficiency in patients on hemodialysis and to investigate the association between vitamin D, ultra-sensitive C-reactive protein (US-CRP), neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). Method: Cross-sectional study of 80 patients on hemodialysis, divided into two groups: a serum 25-OH-vitamin D level < 20 ng/mL was considered to be vitamin D deficiency and a serum level ≥ 20 ng/mL was regarded as normal. The relationship between the parameters was defined with Spearman’s correlation analysis. Results: 40 % of the patients had vitamin D deficiency. There were significant differences between groups in US-CRP (p = 0.047), NLR (p = 0.039), PLR (p = 0.042) and treatment with vitamin D analogues (p = 0.022). Vitamin D had a significant negative correlation with US-CRP (p = 0.026), NLR (p = 0.013) and PLR (p = 0.022). Conclusions: The prevalence of vitamin D deficiency was 40 %. The values of US-CRP, NLR and PLR were significantly higher in the presence of vitamin D deficiency. A significant inverse correlation was found between vitamin D levels and US-CRP, NLR and PLR.

ABSTRACT

In December 2019 a novel coronavirus (SARS-CoV-2) was identified in Wuhan, China, and became rapidly the worst pandemic in 100 years. Coronaviruses are respiratory viruses that can cause diseases ranging from mild to fatal lower respiratory tract infections. In a fraction of the affected patients, coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, can lead to acute respiratory distress syndrome (ARDS) and intensive care unit (ICU) admission, both associated with high mortality. To date, the existing evidence suggests a leading role of the immune system in the pathogenesis of severe COVID-19, including mechanisms associated with hyperinflammation, immune evasion, cytokine release syndrome, depletion of functional T cells, and ineffective humoral immunity. Here we discuss the current evidence regarding these findings.

ABSTRACT

La colecistitis aguda (CA) es la principal complicación de la litiasis vesicular. Existe evidencia que respalda el hecho que la proteína C reactiva (PCR) se elevaría en distintos niveles según gravedad de la CA. El objetivo de este estudio fue determinar asociación entre valores de PCR y estadios clínicos de gravedad de CA. Serie de casos consecutivos de adultos con CA diagnosticada por clínica, ultrasonografía y criterios de Tokio; tratados en un centro de salud terciario de La Paz, Bolivia (diciembre 2019 y enero 2020). La variable resultado fue niveles de PCR. Otras de interés fueron variables biodemográficas. Se aplicó estadística descriptiva (cálculo de porcentajes, de medidas de tendencia central y de dispersión); y posteriormente, se aplicaron estadísticas analíticas para estudiar asociación entre variables (test exacto de Fisher para variables categóricas y t de student para variables continuas). Se estudiaron 44 pacientes (33 con CA leve y 10 con CA moderada), con edad promedio de 51,7±15,3 años; 59,1 % de sexo femenino. El peso, estatura e IMC promedio fueron 69,6±10,3 kg; 1,6±0,1 m; y 27,0±3,1 kg/m2 respectivamente. Las cifras promedio de PCR fueron 9,0±11,6 y 29,5±20,2 en los subgrupos CA leve y moderada respectivamente (p=0,001). Los valores de PCR se asociaron a dos estadios de gravedad clínica de CA.


Serum levels of C-reactive protein as a marker of gravity of acute cholecystitis. Prospective series of cases. Acute cholecystitis (AC) is the main complication of cholelithiasis. There is evidence supporting the fact that C-reactive protein (CRP) would rise at different levels depending on severity of AC. The objective of this study was to determine the association between CRP values and clinical stages of CA severity. Series of consecutive cases of adults with AC diagnosed by clinical, ultrasound and Tokyo criteria; treated at a tertiary health center in La Paz, Bolivia between December 2019 and January 2020. The result variable was CRP determination. Others of interest were biodemographic variables. Descriptive statistics (calculation of percentages, measures of central tendency and dispersion) were applied; later, analytical statistics were applied to study the association between variables (Fisher's exact test for categorical variables and Student's t test for continuous variables). Also, 44 patients were treated (33 with mild AC and 10 with moderate AC), with an average age of 51.7±15.3 years; 59.1 % female. Average weight, height and BMI were 69.6±10.3 kg; 1.59±0.1 m; and 27±3.1 kg/m2 respectively. The mean CRP values were 9.0±11.6 and 29.5±20.2 in the mild and moderate AC subgroups respectively (p=0.001). CRP values were associated with two stages of clinical severity of Acute Cholecystitis.

ABSTRACT

Chronic hepatotoxicity is a debilitating and frequently life-threatening disease resulting in progressive liver failure. The toxic chemical, thioacetamide (TAA) is used to evaluate hepatoprotective agents, and the polyphenolic compound, resveratrol was proposed as a novel treatment for diseases with hyperactivation of the mammalian target of rapamycin (mTOR) cell signaling pathway. This analysis sought to investigate the potential protective effect of resveratrol against liver injury induced by TAA via the inhibition of hepatic mTOR. Model group rats received several injections of TAA (200 mg/kg; twice a week for 8 weeks) before being sacrificed at week 10 and the protective group was pretreated with resveratrol (20 mg/kg) daily for two weeks prior to TAA injections and continued receiving both agents until the end of the experiment. Harvested liver tissues were examined using light microscopy and liver homogenates were assayed for biomarkers of inflammation and assessed the levels of mTOR protein in all animal groups. In addition, blood samples were assayed for biomarkers of liver injury enzyme. TAA substantially damaged the hepatic tissue of the model group such as infiltration of inflammatory cells, vacuolated cytoplasm, dark pyknotic nuclei, and dilated congested blood vessel that were effectively protected by resveratrol. Resveratrol also significantly (p<0.05) inhibited TAA-induced mTOR, high sensitivity c-reactive protein (hs-CRP), tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in harvested liver homogenates and blood samples. Thus, we conclude that resveratrol effectively protects against TAA-induced hepatotoxicity in rats, possibly due to the inhibition of mTOR and inflammation.


La hepatotoxicidad crónica es una enfermedad debilitante y potencialmente mortal que produce insuficiencia hepática progresiva. La toxicidad del químico de la tioacetamida (TAA) se utiliza para evaluar los agentes hepatoprotectores y el compuesto polifenólico, resveratrol, se propuso como un nuevo tratamiento para enfermedades con hiperactivación de la vía de señalización celular mTOR (mammalian Target of Rapamycin). Aquí buscamos investigar el posible efecto protector del resveratrol contra la lesión hepática inducida por TAA a través de la inhibición de la vía de señalización mTOR en hepatocitos. Las ratas del grupo modelo recibieron varias inyecciones de TAA (200 mg / kg; dos veces por semana durante 8 semanas) antes de ser sacrificadas en la semana 10 y el grupo protector se trató previamente con resveratrol (20 mg / kg) diariamente durante dos semanas antes de las inyecciones de TAA y continuó recibiendo ambos agentes hasta el final del experimento. Se examinaron los tejidos hepáticos recolectados usando microscopía óptica y se analizaron los homogeneizados hepáticos para detectar biomarcadores de inflamación y se evaluaron los niveles de proteína mTOR en todos los grupos de animales. Además, se analizaron muestras de sangre para detectar biomarcadores de la enzima de lesión hepática. TAA dañó sustancialmente el tejido hepático del grupo modelo, con infiltración de células inflamatorias, citoplasma vacuolado, núcleos picnóticos oscuros y vasos sanguíneos congestionados dilatados que estaban efectivamente protegidos por el resveratrol. El resveratrol también inhibió significativamente (p <0.05) mTOR, proteína C-reactiva (hs-CRP), factor de necrosis tumoral alfa (TNF-α), interleucina-6 (IL-6), alanina aminotransferasa (ALT ) y aspartato aminotransferasa (AST) en las muestras de sangre y de hígados recolectados. En conclusión, el resveratrol protege eficazmente contra la hepatotoxicidad inducida por TAA en ratas, posiblemente debido a la inhibición de mTOR y de la inflamación.

ABSTRACT

Abstract Introduction: Sudden hearing loss is a significant otologic emergency. Previous studies have revealed a coexistence of sudden hearing loss with chronic inflammation. The predictive importance of C-reactive protein/albumin values as a prognostic factor has been shown in various inflammatory and tumoral conditions. Objectives: The aim of this study was to determine whether the C-reactive protein/albumin ratio in sudden hearing loss can be used for prognostic purposes and whether there is a relationship between the neutrophil/lymphocyte ratio and the C-reactive protein/albumin ratio. Methods: A retrospective examination was made of 40 patients diagnosed with idiopathic sudden hearing loss and a control group of 45 healthy subjects. The pure tone averages of all the patients were determined on first presentation and repeated at 3 months after the treatment. The patients were separated into 2 groups according to the response to treatment. The neutrophil/lynphocyte ratio and the C-reactive protein/albumin ratios were calculated from the laboratory tests. Results: The patients included 16 females and 24 males with a mean age of 44.1 ± 14.2 years and the control group was composed of 23 females and 22 males with a mean age of 42.2 ± 13.8 years. The mean C-reactive protein/albumin ratio was 0.95 ± 0.47 in the patient group and 0.74 ± 0.13 in the control group. The difference was statistically significant (p = 0.009). The mean C-reactive protein/albumin ratio was 0.79 ± 0.12 in the response to treatment group and 1.27 ± 0.72 in the non-response group, with no significant difference determined between the groups (p = 0.418). The mean neutrophil/lymphocyte ratio was 3.52 ± 3.00 in the response to treatment group and 4.90 ± 4.60 in the non-response group, with no statistically significant difference determined between the groups (p = 0.261). Conclusion: C-reactive/albumin ratio was significantly higher in patients with sudden hearing loss than in the control group. Although C-reactive protein/albumin ratio was found to be lower in sudden hearing loss patients who responded to treatment compared to those who did not, the difference between two groups was not statistically significant.


Resumo Introdução: A perda auditiva neurossensorial súbita ou surdez súbita é uma emergência otológica significativa. Estudos anteriores revelaram uma coexistência dessa condição com inflamação crônica. A importância preditiva dos valores da relação proteína C-reativa/albumina como fator prognóstico tem sido demonstrada em várias condições inflamatórias e tumorais. Objetivos: O objetivo deste estudo foi determinar se a relação proteína C-reativa/albumina na perda auditiva neurossensorial súbita pode ser usada para fins prognósticos e se existe uma associação entre as relações neutrófilo/linfócito e proteína C-reativa/albumina. Método: Foram avaliados retrospectivamente 40 pacientes com diagnóstico de perda auditiva neurossensorial súbita idiopática e um grupo controle de 45 indivíduos saudáveis. As médias de tons puros de todos os pacientes foram determinadas na primeira consulta e repetidas 3 meses após o tratamento. Os pacientes foram separados em 2 grupos de acordo com a resposta ao tratamento. As relações neutrófilo/linfócito e proteína C-reativa/albumina foram calculadas a partir de testes laboratoriais. Resultados: Os pacientes incluíam 16 mulheres e 24 homens, com média de 44,1 ± 14,2 anos, e o grupo controle por 23 mulheres e 22 homens, com média de 42,2 ± 13,8 anos. A média da relação proteína C-reativa/albumina foi de 0,95 ± 0,47 no grupo de pacientes e de 0,74 ± 0,13 no grupo controle e a diferença foi estatisticamente significante (p = 0,009). A média da relação proteína C-reativa/albumina foi de 0,79 ± 0,12 do grupo com resposta ao tratamento e de 1,27 ± 0,72 no grupo sem resposta, sem diferença significante entre os grupos (p = 0,418). A média da relação neutrófilo/linfócito foi de 3,52 ± 3,00 no grupo com resposta ao tratamento e de 4,90 ± 4,60 no grupo sem resposta, sem diferença estatisticamente significativa entre os grupos (p = 0,261). Conclusão: A relação proteína C-reativa/albumina foi significantemente maior nos pacientes com perda auditiva neurossensorial súbita do que no grupo controle. No entanto, embora a relação proteína C-reativa/albumina tenha sido menor nos pacientes com perda auditiva neurossensorial súbita que responderam ao tratamento em comparação a aqueles que não apresentaram resposta, a diferença entre os dois grupos não foi estatisticamente significante.

ABSTRACT

Abstract Background: Periodontitis and coronary artery disease (CAD) share an inflammatory etiology; there is a recent concern regarding the investigation of an association between these two conditions. Current theories indicate that cytokines and proteins have an important role in this process. C-reactive protein and interleukin-6 are inflammatory derivatives produced in the presence of periodontitis and in the pathophysiology of coronary disease. The polymorphisms of CRP + 1444 C > T and IL6-174 G > C are recognized in the literature as being related to CAD. Objective: This study investigates the association between periodontitis and coronary artery disease, through the presence of PCR and IL-6 polymorphisms. Methods: We selected 80 patients who underwent diagnostic catheterization in the HU of UFSM. The presence of periodontitis was determined by the Community Periodontal Index, whereas the CAD was established by the medical report. DNA was collected from a saliva sample and the presence of polymorphism was determined by PCR and restriction enzymes. A significance level of 5% was adopted. Results: The mean age of all participants (p = 0.035, OR 2.65; 95%CI: (1.02-6.87) male gender (p = 0.012, OR 3.37; 95% CI: (1.28- (p = 0.013, OR 3.66; 95% CI: (1.27-10.5)), PCR polymorphism + 1444C > T (p = 0.001, OR 6.37; 95% CI:, (2.25-17.9)) and IL6 -174 G > C polymorphism (p = 0.025, OR 2.87, 95% CI: (1.09-7.55)) were statistically associated with the presence of CAD. Age > 60 years and presence of the PCR +1444 C > T polymorphism remained independently associated with CAD after adjustment by logistic regression. Conclusions: The presence of the PCR + 1444 C > T polymorphism in this study was independently associated with the presence of coronary artery disease.


Resumo Fundamento: A periodontite e a doença arterial coronariana (DAC) compartilham uma etiologia inflamatória. Existe preocupação na investigação de associação entre essas duas condições. Há citocinas e proteínas com papel importante neste processo, como a proteína C-reativa (PCR) e a interleucina 6 (IL-6), que são derivados inflamatórios produzidos na presença da periodontite e na fisiopatologia da DAC. Os polimorfismos da PCR+1444 C > T e da IL-6 -174 G > C são reconhecidos na literatura como relacionados à DAC. Objetivo: Este estudo objetiva comprovar a associação entre periodontite e DAC, através da presença dos polimorfismos da PCR e da IL-6. Métodos: Foram selecionados 80 pacientes que se submeteram ao cateterismo diagnóstico no Hospital Universitário da Universidade Federal de Santa Maria (UFSM). A periodontite foi determinada pelo índice periodontal comunitário; a DAC, pelo laudo médico. Foi coletado o ácido desoxirribonucleico (DNA) pela saliva e estabelecido o polimorfismo pela avaliação da PCR/RFLP. Foi adotado um nível de significância estatística de 5%. Resultados: A idade mediana de todos os participantes (p = 0,035; OR 2,65; IC 95% [1,02-6,87]), gênero masculino (p = 0,012; OR 3,37; IC 95% [1,28-8,9]), periodontite (p = 0,013; OR 3,66; IC 95% [1,27-10,5]), polimorfismo da PCR +1444 C > T (p = 0,001; OR 6,37; IC 95% [2,25-17,9]) e polimorfismo da IL-6 -174G > C (p = 0,025; OR 2,87; IC 95% [1,09-7,55]) foram estatisticamente relacionados à DAC. Após ajuste com a regressão logística, mantiveram-se independentemente associadas à DAC a idade maior que 60 anos e o polimorfismo da PCR +1444 C > T. Conclusões: O polimorfismo da PCR +1444 C > T, neste estudo, esteve independentemente relacionado à DAC.

ABSTRACT

Abstract Alzheimer's disease (AD) is the most common cause of dementia. Despite numerous studies on the subject, the pathologies for AD are still unclear and there is still no ideal biomarker for diagnosis. The present study aimed to investigate clinical significance of human complement factor H (CFH) in patients with late-onset AD. Methods: The present prospective study included 187 late-onset AD patients who went to our hospital from January 2015 to December 2017. One hundred patients with mild cognitive impairment (MCI) and 80 healthy individuals who were age and gender matched to AD patients were enrolled as controls. Demographic data such as age, gender, and education duration were recorded. Blood samples were collected and serum levels of C-reactive protein (CRP), CFH, and brain-derived neurotrophic factor (BDNF) were determined by Enzyme-linked immunosorbent assay (ELISA). The mini-mental state examination (MMSE) score was measured for all patients. Results: No significant difference was found in age, gender, and education duration for all participants. The MMSE scores showed AD patients had lower MMES scores than the other two groups. All factors of CFH, CRP, and BDNF were dramatically decreased in AD patients compared with the MCI and the ealthy control. Levels of CFH were found to be positively correlated with levels of CRP; however, no significant correlation was found between CFH and BDNF, nor CFH and MMSE. Conclusion: CFH was decreased in late-onset AD patients, and serum levels of CFH was correlated with serum levels of CRP, but not MMSE and BDNF. These results may provide more clinical evidences for the role of CFH in AD patients.


Resumo A doença de Alzheimer (DA) é a causa mais comum de demência. Apesar de inúmeros estudos sobre DA, suas patologias ainda não são claras e ainda não existe um biomarcador ideal para o diagnóstico da condição. O presente estudo teve como objetivo investigar a significância clínica do fator H do complemento humano (CFH) em pacientes com DA de início tardio. Métodos: O presente estudo prospectivo incluiu um total de 187 pacientes com DA de início tardio que foram ao nosso hospital entre janeiro de 2015 e dezembro de 2017. Cem pacientes com comprometimento cognitivo leve (CCL) e 80 indivíduos saudáveis com idade e sexo pareados com pacientes com DA foram incluídos como controle. Dados demográficos como idade, sexo e duração da educação foram registrados. As amostras de sangue foram coletadas e os níveis séricos de proteína C-reativa (PCR), CFH e fator neurotrófico derivado do cérebro (BDNF) foram determinados pelo ensaio imunoabsorvente ligado à enzima (ELISA). O escore do miniexame do estado mental (MEEM) foi medido para todos os pacientes. Resultados: Não foram encontradas diferenças significativas em idade, sexo e duração da educação para todos os participantes. Pacientes com DA tinham os menores escores de MEEM em relação aos outros dois grupos. Todos os fatores de CFH, PCR e BDNF diminuíram drasticamente em pacientes com DA em comparação com o CCL e o controle saudável. Os níveis de CFH mostraram correlação positiva com os níveis de PCR; no entanto, não foi encontrada correlação significativa entre CFH e BDNF, nem CFH e MEEM. Conclusão: A CFH diminuiu nos pacientes com DA de início tardio e os níveis séricos de CFH foram correlacionados com os níveis séricos de PCR, mas não o MEEM e o BDNF. Esses resultados podem fornecer mais evidências clínicas do papel da CFH em pacientes com DA.

ABSTRACT

Abstract Background: Psoriasis is a chronic immune-mediated inflammatory skin disease that is associated with cardiovascular comorbidities. Objectives: The objective of this retrospective study is to assess the C-reactive protein, monocyte-to-high-density-lipoprotein ratio, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and monocyte-to-lymphocyte ratio as inflammatory markers in patients with psoriasis and to search for a relationship between these parameters and psoriasis severity, as defined by the psoriasis area and severity index. Methods: There were 94 patients with psoriasis and 118 healthy controls enrolled in the study. The C-reactive protein, monocyte-to-high-density-lipoprotein ratio, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and monocyte-to-lymphocyte ratio values of two groups were retrospectively evaluated. Results: Statistically significant differences were observed in terms of C-reactive protein, monocyte-to-high-density-lipoprotein ratio, neutrophil-to-lymphocyte ratio and monocyte-to-lymphocyte ratio between the patient and control groups (p = 0.001, p = 0.003, p = 0.038, and p = 0.007, respectively). Positive correlations were found between the psoriasis area and severity index and the values of C-reactive protein, monocyte-to-high-density-lipoprotein ratio, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and monocyte-to-lymphocyte ratio (r: 0.381; p < 0.01, r: 0.203; p < 0.05, r: 0.268; p < 0.01, r: 0.374; p < 0.01, r: 0.294; p < 0.01, respectively). Study limitations: The small sample size and the retrospective design of the study are limitations. Conclusion: Elevated C-reactive protein, monocyte-to-high-density-lipoprotein ratio, neutrophil-to-lymphocyte ratio, and monocyte-to-lymphocyte ratio were significantly associated with psoriasis. A positive correlation between C-reactive protein and monocyte-to-high-density-lipoprotein ratio leads to the suggestion that monocyte-to-high-density-lipoprotein ratio might be a reliable parameter in psoriasis during the follow-up. The relationship between the diasease and inflammatory parameters might provide early detection of cardiovascular morbidities in psoriasis patients.

ABSTRACT

Abstract Introduction Obstrutive sleep apnea syndrome is characterized by repeated episodes of upper airway obstruction, associated with intermittent hypoxia and hypercapnia, and the main risk factor in childhood is adenotonsillar hypertrophy. The lymphocytes in these structures are responsible for local and systemic immune responses. Objective Verify the levels of the inflammatory markers, IL-1β, IL-4, IL-6, IL-8, IL-10, IL-15, TNF-α, CRP and α1-GP, in the tonsils of children with and without obstructive sleep apnea syndrome. Methods This cross-sectional prospective study included 34 children with complains of snoring, difficulty breathing during sleep or recurrent tonsillitis. Patients underwent to a complete otorhinolaryngological examination, nasal endoscopy and polysomnography and were divided into two groups with 17 children each: obstructive sleep apnea syndrome group and control group. All underwent an adenotonsillectomy. Cytokines were measured in the collected tonsils (ELISA and Multiplex methods). Results Statistically significant increasing were observed between IL-8 and IL-10 cytokines of patients with obstructive sleep apnea when compared to the control group; also between c-reactive protein and α1-GP of the tonsils cortical region in children with obstructive sleep apnea syndrome when compared with the medullary region. There were no statistically significant differences for the remaining inflammatory mediators. Conclusion After the analysis of the levels of pro and anti-inflammatory markers (IL-1β, IL-4, IL-6, IL-8, IL-10, Il-15, TNF-α, CRP, α1-GP) in the tonsils, we observed higher levels of markers IL-8 and IL-10 in pediatric patients with obstructive sleep apnea syndrome.


Resumo Introdução A síndrome da apneia obstrutiva do sono é caracterizada por episódios repetidos de obstrução das vias aéreas superiores, associados a hipóxia intermitente e hipercapnia, e o principal fator de risco na infância é a hipertrofia adenotonsilar. Os linfócitos nessas estruturas são responsáveis por respostas imunes locais e sistêmicas. Objetivo Dosar os marcadores inflamatórios, IL-1β, IL-4, IL-6, IL-8, IL-10, IL-15, TNF-α, PCR e α1-GP, nas tonsilas de crianças com e sem síndrome da apneia obstrutiva do sono. Método Estudamos prospectivamente 34 crianças que se queixavam de ronco, dificuldade para respirar durante o sono ou tonsilites recorrentes. Os pacientes foram submetidos a exame otorrinolaringológico completo, endoscopia nasal e polissonografia e foram divididos em dois grupos com 17 crianças cada: síndrome de apneia obstrutiva do sono e controle. Todos foram submetidos à adenotonsilectomia. As citocinas foram medidas nas tonsilas coletadas (métodos ELISA e Multiplex). Resultados Com diferenças estatisticamente significantes, observou-se aumento das citocinas IL-8 e IL-10 em pacientes com apneia obstrutiva do sono em comparação ao grupo controle, assim como aumento dos níveis de proteína C reativa e de α1-GP na região cortical das tonsilas de crianças portadoras de síndrome da apneia obstrutiva do sono em comparação com a região medular. Não houve diferenças estatisticamente significantes para o restante dos mediadores inflamatórios. Conclusão Após a análise dos níveis de marcadores pró e anti-inflamatórios (IL-1β, IL-4, IL-6, IL-8, IL-10, Il-15, TNF-α, PCR, α1-GP) nas tonsilas, observamos níveis mais altos de marcadores IL-8 e IL-10 em pacientes pediátricos com síndrome da apneia obstrutiva do sono.

ABSTRACT

Abstract The evidence is inconclusive regarding the effect of periodontal treatment on glycemic control and systemic inflammation in patients with type 2 diabetes (T2D) and periodontitis Objective: To evaluate the effect of scaling and root planing (SRP) on the metabolic control and systemic inflammation of patients with type 2 diabetes (T2D). Methodology: A literature search was conducted using the MEDLINE database via PubMed and the Cochrane Central Register of Controlled Trials, from their oldest records up to July 2018. Only randomized clinical trials (RCT) were considered eligible for evaluating the effect of periodontal treatment on markers of metabolic control [glycated hemoglobin (HbA1C)] and systemic inflammation [C-reactive protein (CRP)] in patients with T2D. The quality of the studies was evaluated using the Cochrane Collaboration risk assessment tool. Meta-analyses were performed for HbA1c and CRP using random effects models. The size of the overall intervention effect was estimated by calculating the weighted average of the differences in means (DM) between the groups in each study. Heterogeneity was assessed using the Q-statistic method (x2 and I²). The level of significance was established at p<0.05. Results: Nine RCT were included. SRP was effective in reducing HbA1c [DM=0.56 (0.36-0.75); p<0.01] and CRP [DM=1.89 (1.70-2.08); p<0.01]. No heterogeneity was detected (I2=0%, p>0.05). Conclusions: SRP has an impact on metabolic control and reduction of systemic inflammation of patients with T2D.

ABSTRACT

OBJECTIVE@#To explore the therapeutic effect and the mechanism of the adjuvant treatment with moxibustion on coronavirus disease 2019 (COVID-19).@*METHODS@#A total of 95 patients with COVID-19 were randomly divided into a moxibustion group (45 cases) and a basic treatment group (50 cases). The routine treatment of western medicine was applied in the patients of both groups. In the moxibustion group, on the base of the treatment of western medicine, moxibustion was applied to Dazhui (GV 14), Feishu (BL 13), Qihai (CV 6) and Zusanli (ST 36), once daily and consecutively for 14 days. At the end of treatment courses, clinical symptom scores for cough, asthmatic breathing, chest oppression and short breath, as well as their remission rates were compared between the two groups before and after treatment. Before and after treatment, the white blood cell (WBC) count, the levels of c-reactive protein (CRP) and interleukin-6 (IL-6) and the absolute number of T lymphocyte subsets, i.e. , and of the peripheral blood were compared in the patients between the two groups. The principal component analysis was adopted to analyze the common data extracted from the above 10 clinical indexes variables and comprehensively evaluate the differences in the therapeutic effect of two regimens.@*RESULTS@#The clinical symptom scores were all decreased after treatment in both of the moxibustion group and the basic treatment group as compared with those before treatment (@*CONCLUSION@#On the base of the routine treatment with western medicine, moxibustion therapy supplemented relieves the clinical symptoms, reduces the levels of inflammatory indexes, i.e. IL-6 and CRP as well as improves the absolute number of peripheral T lymphocyte subsets. The clinical therapeutic effect of such regimen with moxibustion supplemented is significantly better than the simple routine treatment of western medicine.

ABSTRACT

OBJECTIVE@#To study the clinical significance and cut-off value of white blood cell (WBC) count in the diagnosis of early-onset sepsis (EOS) in neonates.@*METHODS@#A retrospective analysis was performed on 306 neonates with EOS who were admitted from January 2019 to March 2020. A total of 580 children without infection who were admitted during the same period of time were enrolled as the control group. General status and WBC count were compared between the two groups. The diagnostic value of WBC count was analyzed based on the diagnostic and therapeutic protocol of neonatal sepsis in 2003 (referred to as the 2003 diagnostic and therapeutic protocol) and the expert consensus on the diagnosis and treatment of neonatal sepsis (2019 edition) (referred to as the 2019 expert consensus).@*RESULTS@#According to the two different diagnosis and treatment protocols, the statistical analysis showed that WBC count had a relatively positive rate (51.3% and 32.0% respectively) but a relatively high specificity (93.3% and 98.6% respectively). The receiver operating characteristic (ROC) curve analysis showed that the area under the ROC curve of WBC count in the 2003 diagnostic and therapeutic protocol was larger than that in the 2019 expert consensus (P<0.05).@*CONCLUSIONS@#The cut-off value of WBC ≥25×10
