ABSTRACT

The study was designed to investigate the effect of Coconut Oil on the levels of some liver and hematological parameters in carbon tetrachloride intoxicated rabbits. Also the antioxidant capacity of Coconut Oil for various concentrations was assessed on the basis of percent scavenging of (DPPH) free radical. Experimental animals were divided into five groups, eight rabbits in each group. These were: group A (Normal control), group B (Toxic control), group C (Standard control), group D (Treated with Coconut Oil 50 mL/kg body weight after CCl4 intoxication), group E (Treated with Coconut Oil 200 mL/kg body weight after CCl4 intoxication). The effects observed were compared with a standard hepatoprotective drug silymarine (50 mL/kg body weight). The Coconut Oil (200 mL/kg body weight) significantly (P<0.05) reduced the elevated serum levels of alanine transaminase (ALT), aspartate transaminase (AST) and alkaline phosphatase (ALP) when compared to a toxic control rabbits. The results of extract treated rabbits were similar to silymarine administered rabbits group. Treatment with Coconut Oil root and silymarine caused no significant changes in RBC, Platelets, (Hb), (MCH) concentration and (HCT) values. However, significant (P<0.05) increase was observed in the total WBC count. The present study suggested that Coconut Oil can be used as an herbal alternative (need further exploration i.e to detect its bioactive compound and its efficacy) for hepatoprotective activit.


O estudo foi desenhado para investigar o efeito do óleo de coco nos níveis de alguns parâmetros hepáticos e hematológicos em coelhos intoxicados com tetracloreto de carbono. Também a capacidade antioxidante do óleo de coco para várias concentrações foi avaliada com base na porcentagem de eliminação de radicais livres (DPPH). Os animais experimentais foram divididos em cinco grupos, oito coelhos em cada grupo. Estes foram: grupo A (controle normal), grupo B (controle tóxico), grupo C (controle padrão), grupo D (tratado com óleo de coco 50 mL/kg de peso corporal após intoxicação por CCl4), grupo E (tratado com óleo de coco 200 mL/kg de peso corporal após intoxicação por CCl4). Os efeitos observados foram comparados com um fármaco hepatoprotetor padrão silimarina (50 mL/kg de peso corporal). O óleo de coco (200 mL/kg de peso corporal) reduziu significativamente (P<0,05) os níveis séricos elevados de alanina transaminase (ALT), aspartato transaminase (AST) e fosfatase alcalina (ALP), quando comparado a um coelho controle tóxico. Os resultados dos coelhos tratados com extrato foram semelhantes aos do grupo de coelhos administrados com silimarina. O tratamento com raiz de óleo de coco e silimarina não causou alterações significativas nos valores de RBC, Plaquetas, (Hb), (MCH) e (HCT). No entanto, observou-se aumento significativo (P<0,05) na contagem total de leucócitos. O presente estudo sugeriu que o óleo de coco pode ser usado como uma alternativa fitoterápica (precisa de mais exploração, ou seja, para detectar seu composto bioativo e sua eficácia) para atividade hepatoprotetora.

ABSTRACT

Introdução: A disbiose intestinal é uma característica comum na síndrome cardiorrenal e está associada ao aumento de toxinas urêmicas, como o N-óxido de trimetilamina (TMAO), que estão envolvidas com a inflamação e mortalidade cardiovascular. A castanha-do-Brasil (semente típica brasileira) possui propriedades anti-inflamatórias e antioxidantes, mas não há evidências dos seus efeitos na modulação da microbiota intestinal e redução de toxinas urêmicas. Objetivo: Avaliar o impacto do consumo de castanha-do-Brasil nos níveis de TMAO e marcadores de inflamação em um paciente com síndrome cardiorrenal. Métodos: Um paciente com doença arterial coronariana (66 anos e IMC, 26 kg/m2), estágio 3 da DRC (TFGe 36 mL/min), recebeu uma castanha-do-Brasil por dia durante três meses. Resultados: Os níveis plasmáticos de TMAO e a expressão de mRNA de NF-κB foram reduzidos e a atividade da glutationa peroxidase (GPx) aumentou após esta intervenção. Conclusão: A prescrição de castanha-do-Brasil pode ser uma estratégia promissora para mitigar as complicações relacionadas à síndrome cardiorrenal. Este caso apoia o conceito de "alimento como remédio" visando o fenótipo urêmico na síndrome cardiorrenal.


Introduction: Gut dysbiosis is a common feature in cardiorenal syndrome, and it is linked to increased uremic toxins, like trimethylamine-n-oxide (TMAO), which are involved with inflammation and cardiovascular mortality. Brazil nut (typical Brazilian seed) has anti-inflammatory and antioxidant properties, but there is no evidence of the effects of gut microbiota modulation and reduction of uremic toxins. Objective: To assess the impact of Brazil nut consumption on TMAO levels and inflammation markers in a patient with cardiorenal syndrome. Methods: Acoronary artery disease patient(66 years and BMI, 26 kg/m2),stage-3 of CKD (eGFR 36 mL/min), receivedone Brazil nut per day for three months. Results: TMAO plasma levels and NF-κB mRNA expression were reduced, and glutathione peroxidase (GPx) activity increased after this intervention. Conclusion: Brazil nut prescription may be a promising strategy to mitigate complications related tothe cardiorenal syndrome. This case supports the concept of "Food as medicine" targeting the uremic phenotype in cardiorenal syndrome.

ABSTRACT

The study was aimed to evaluate the therapeutic effects of Zizyphus oxyphyla leaves methanolic (ZOX-LME), on serum liver, kidney and hematology along with other serum parameters in Carbon tetrachloride (CCl4) intoxicated rabbits. Experimental animals were divided into five groups, six rabbits in each. These were: group NC (normal control), group, TC (toxic control) and group ST i.e. silymarine administered group at dose rate (50) mg/kg body weight (BW). Group ET1 and group ET2 treated with (ZOX-LME) at dose 200 mg/kg BW and 400 mg/kg BW. CCl4 administration caused significant (P> 0.05) impairment in serum liver enzymes, blood factors and other serum indices. Treatment with (ZOX-LME) significantly (P<0.05) reduced and normalized the levels of serum alanine transaminase (ALT) aspartate transaminase (AST) and alkaline phosphatase (ALP) and hematological indices. Also significant (P< 0.05) reduction was observed in creatinine, urea, uric acid, blood urea nitrogen (BUN), and albumin and glucose concentrations. The altered levels of lipid profile and serum electrolytes (Ca, Mg, Cl, Na, K, and P) were significantly (P<0.05) change toward normal levels with (ZOX-LME) feeding. In addition (ZOX-LME) ingestion caused significant improvement in GSH, GST and CAT levels, while reducing the TBARS levels, exhibited antioxidant capacity. Also (ZOX-LME) showed increase inhibition against percent scavenging of 2, 2-diphenile-1-picrylehydrazyle (DPPH) free radical. Significant (P<0.05) normalizing effects were observed with high dose 400 mg/kg BW of (ZOX-LME and were equivalent to silymarine administered groups. The histological study of liver supported the hepatoprotective and renal curative activity of (ZOX-LME).


O estudo teve como objetivo avaliar os efeitos terapêuticos das folhas metanólicas de Zizyphus oxyphyla (ZOX-LME) no fígado, rim e hematologia séricos, juntamente com outros parâmetros séricos em coelhos intoxicados com tetracloreto de carbono (CCl4). Os animais experimentais foram divididos em cinco grupos, seis coelhos em cada. Estes foram: grupo NC (controle normal), grupo TC (controle tóxico) e grupo ST, isto é, grupo administrado com silimarina na taxa de dose (50) mg / kg de peso corporal (PC). Grupo ET1 e grupo ET2 tratado com (ZOX-LME) na dose de 200 mg / kg de peso corporal e 400 mg / kg de peso corporal. A administração de CCl4 causou prejuízo significativo (P > 0,05) nas enzimas hepáticas séricas, fatores sanguíneos e outros índices séricos. O tratamento com (ZOX-LME) reduziu significativamente (P < 0,05) e normalizou os níveis de alanina transaminase (ALT), aspartato transaminase (AST) e fosfatase alcalina (ALP) e os índices hematológicos. Também foi observada redução significativa (P < 0,05) nas concentrações de creatinina, ureia, ácido úrico, nitrogênio ureico no sangue (BUN), albumina e glicose. Os níveis alterados de perfil lipídico e eletrólitos séricos (Ca, Mg, Cl, Na, K e P) foram significativamente (P < 0,05) mudando em direção aos níveis normais com a alimentação (ZOX-LME). Além disso, a ingestão de (ZOX-LME) causou melhora significativa nos níveis de GSH, GST e CAT, enquanto reduzia os níveis de TBARS, exibindo capacidade antioxidante. Também (ZOX-LME) mostrou inibição aumentada contra a eliminação percentual do radical livre 2, 2-difenila-1-picrilehidrazila (DPPH). Efeitos de normalização significativos (P < 0,05) foram observados com altas doses de 400 mg / kg de peso corporal de (ZOX-LME) e foram equivalentes aos grupos administrados com silimarina. O estudo histológico do fígado confirmou a atividade hepatoprotetora e curativa renal de (ZOX-LME).

ABSTRACT

This study aimed to investigate the effective substances and mechanism of Yishen Guluo Mixture in the treatment of chronic glomerulonephritis(CGN) based on metabolomics and serum pharmacochemistry. The rat model of CGN was induced by cationic bovine serum albumin(C-BSA). After intragastric administration of Yishen Guluo Mixture, the biochemical indexes related to renal function(24-hour urinary protein, serum urea nitrogen, and creatinine) were determined, and the efficacy evaluations such as histopathological observation were carried out. The serum biomarkers of Yishen Guluo Mixture in the treatment of CGN were screened out by ultra-performance liquid chromatography-quadrupole time-of-flight/mass spectrometry(UPLC-Q-TOF-MS) combined with multivariate statistical analysis, and the metabolic pathways were analyzed. According to the mass spectrum ion fragment information and metabolic pathway, the components absorbed into the blood(prototypes and metabolites) from Yishen Guluo Mixture were identified and analyzed by using PeakView 1.2 and MetabolitePilot 2.0.4. By integrating metabolomics and serum pharmacochemistry data, a mathematical model of correlation analysis between serum biomarkers and components absorbed into blood was constructed to screen out the potential effective substances of Yishen Guluo Mixture in the treatment of CGN. Yishen Guluo mixture significantly decreased the levels of 24-hour urinary protein, serum urea nitrogen, and creatinine in rats with CGN, and improved the pathological damage of the kidney tissue. Twenty serum biomarkers of Yishen Guluo Mixture in the treatment of CGN, such as arachidonic acid and lysophosphatidylcholine, were screened out, involving arachidonic acid metabolism, glycerol phosphatide metabolism, and other pathways. Based on the serum pharmacochemistry, 8 prototype components and 20 metabolites in the serum-containing Yishen Guluo Mixture were identified. According to the metabolomics and correlation analysis of serum pharmacochemistry, 12 compounds such as genistein absorbed into the blood from Yishen Guluo Mixture were selected as the potential effective substances for the treatment of CGN. Based on metabolomics and serum pharmacochemistry, the effective substances and mechanism of Yishen Guluo Mixture in the treatment of CGN are analyzed and explained in this study, which provides a new idea for the development of innovative traditional Chinese medicine for the treatment of CGN.

ABSTRACT

Introducción: la mortalidad asociada a infarto del miocardio (IM) no solo se debe a complicaciones cardiovasculares, sino también a complicaciones intrahospitalarias no cardiovasculares (CIHNC). El índice leuco-glucémico (ILG) se ha utilizado como un marcador pronóstico para el desarrollo de complicaciones cardiovasculares en el IM. Centramos este estudio en identificar el punto de corte de ILG para el desarrollo de CIHNC en pacientes con infarto de miocardio con elevación del segmento ST (IAMCEST). Material y métodos: en este diseño de un solo centro y transversal, incluimos pacientes con IAMCEST. El análisis bioquímico incluyó glucosa y leucocitos; se calculó ILG. Se realizaron análisis univariados y bivariados, curva ROC y análisis multivariado para el desarrollo de IAMCEST. Resultados: incluimos 1294 pacientes, 79.8% hombres y 20.2% mujeres. Las principales comorbilidades fueron: hipertensión arterial sistémica, diabetes mellitus y dislipidemia. Seiscientos cuarenta y cuatro pacientes (49.8%) presentaron CIHNC. El ILG > 1200 con área bajo la curva (AUC) 0.817 predice el desarrollo de CIHNC en pacientes con IAMCEST. Las variables que aumentaron el desarrollo de CIHNC fueron: ILG > 1200, creatinina > 0.91 mg/dL, diabetes mellitus y edad > 65 años. La neumonía intrahospitalaria y las complicaciones cardiovasculares aumentaron el riesgo de muerte entre los pacientes con IAMCEST. Conclusión: un LGI > 1200 aumentó más de nueve veces el riesgo de desarrollo de CIHNC en pacientes con IAMCEST.


Background: The myocardial infarction-associated (MI) mortality is not only due cardiovascular complications, but intrahospital non-cardiovascular complications (IHnCVCs). The leuko-glycemic index (LGI) has been used as a prognostic marker for the development of cardiovascular complications in MI. We focused this study on identifying the cut-off point of LGI for the IHnCVCs development in patients with ST-segment elevation myocardial infarction (STEMI).Material and methods: In this single-center and cross-sectional design, we included patients with STEMI. The biochemical analysis included glucose and leucocytes; with them we calculated the LGI. Receiver operating characteristic curve, univariate and bivariate analysis, and multivariate analysis for IHnCVCs development were performed. A p < 0.05 was considered statistically significant. Results: We included 1294 patients, 79.8% were men and 20.2% women. The main comorbidities were hypertension, diabetes mellitus and dyslipidemia. Six hundred forty-four (49.8%) patients presented IHNCVCs. The LGI > 1200 (AUC 0.817) predict the IHNCVCs development in STEMI patients. The variables that increased the IHNCVCs development were LGI > 1200, creatinine > 0.91 mg/dL, diabetes mellitus and age > 65 years. Hospital acquired pneumonia and cardiovascular complications increase the risk of death among STEMI patients. Conclusion: A LGI > 1200 increased, just over nine times, the risk of IHnCVC development in STEMI patients.

ABSTRACT

Background: Organic colonic manifestation may be difficult to be differentiated from functional one. Inflammatory bowel disease (IBD) is a common chronic inflammatory and destructive disease of the bowel wall. Chronic inflammation is associated with ulcerations, strictures, perforations, and it is a risk factor for dysplasia and cancer. To reduce these long-standing complications, IBD patients are in a continuous need for early diagnosis1. Markers, such as erythrocyte sedimentation rate (ESR), and c-reactive protein (CRP), fecal calprotectin (FC) have been widely used as noninvasive parameters for IBD monitoring. We aimed, in this current study, to evaluate the value of fecal calprotectin and other noninvasive biomarkers in predicting abnormal histologic findings in patients undergoing colonoscopy.in addition to determine the cutoff value which predict IBD2. Methods: The present prospective study included 160 patients with complaint of colicky abdominal pain with frequent diarrhea associated with mucous and infrequent bleeding per rectum for more than 6 months. They presented partial improvement with medication and recurrence once stopping the treatment These patients had been recently diagnosed with IBD at many primary healthcare centers covering the areas of the Kafrelsheikh and Zagazik governorate in the North of Egyptian Nile delta. After complete history, clinical examination, and laboratory investigation, they were referred to the IBD clinic at Kafrelsheikh University Hospital for assessment and ileocolonoscopy with biopsies. Results: There was a wide spectrum of age of the studied patients, with mean age 40.12±7.88 (minimum 18 and maximum 56 years). Regarding gender, males represented 87.5% of the studied patients. Forty percent of the patients with colonic manifestation were smokers, 57% preferred a spicy diet, and the majority had low educational level (77.5%). Forty percent had obvious blood in stool, 55% had occult blood, and raised ESR CRP occurred in 32.5% and 50%, respectively. Fecal calprotectin cutoff was>159, with sensitivity 92.8% and specificity 97.5%. Conclusions: Biomarkers (FC, ESR, CRP) can be used as noninvasive parameters for the early diagnosis and prediction of organic colonic disease. Fecal calprotectin in the IBD group revealed significant area under the curve (AUC) values and cutoff> 159, with sensitivity 92.8% and specificity 97.5%. (AU)

ABSTRACT

Objective: To explore the value of the assessment of plasma trimethylamine N-oxide (TMAO) combined with N-terminal pro-B-type natriuretic peptide (NT-proBNP) on predicting the all-cause mortality, length of hospitalization, and hospital cost in ischemic heart failure (IHF) patients. Methods: This prospective cohort study included 189 patients (157 males, mean age (64.0±10.5) years) with a left ventricular ejection fraction<45% caused by coronary artery disease, who hospitalized in our department from March 2016 to December 2020. Baseline data, including demographics, comorbid conditions and laboratory examination, were analyzed. The cumulative rate of all-cause mortality was evaluated using the Kaplan-Meier method and compared between the groups according to the log-rank test. Relative risks were reported as hazard ratios (HR) and 95% confidence interval (95%CI) calculated using the Cox proportional-hazards analysis, with stepwise adjustment for covariables. Spearman correlation analysis was then performed to determine the relationship between TMAO combined with NT-proBNP and length of hospitalization and hospital cost. Results: There were 50 patients in the low TMAO+low NT-proBNP group, 89 patients in high TMAO or high NT-proBNP group, 50 patients in high TMAO+high NT-proBNP group. The mean follow-up period was 3.0 years. Death occurred in 70 patients (37.0%), 27 patients (54.0%) in high TMAO+high NT-proBNP group, 29 patients (32.6%) in high TMAO or high NT-proBNP group and 14 patients (28.0%) in low TMAO+low NT-proBNP group. TMAO, in combination with NT-proBNP, improved all-cause mortality prediction in IHF patients when stratified as none, one or both biomarker(s) elevation, with the highest risk of all-cause mortality in high TMAO+high NT-proBNP group (HR=3.62, 95%CI 1.89-6.96, P<0.001). ROC curve analysis further confirmed that TMAO combined with NT-proBNP strengthened the prediction performance on the risk of all-cause death (AUC=0.727(95%CI 0.640-0.813), sensitivity 55.0%, characteristic 83.1%). Spearman correlation analysis showed that IHF patients with high TMAO and high NT-proBNP were positively associated with longer duration of hospitalization (r=0.191,P=0.009), but not associated with higher hospital cost (r=0.030, P=0.686). Conclusions: TMAO combined with NT-proBNP are valuable prediction tool on risk stratification of patients with IHF, and those with two biomarkers elevation face the highest risk of mortality during follow-up period, and are associated with the longer hospital stay.

ABSTRACT

OBJECTIVES@#There is a high coagulation state in pregnant women, which is prone to coagulation and fibrinolysis system dysfunction. This study aims to explore the latest coagulation markers-thrombomodulin (TM), thrombin-antithrombin complex (TAT), plasmin-α2 plasmin inhibitor complex (PIC), and tissue plasminogen activator/plasminogen activator inhibitor compound (tPAI-C) in different stages of pregnancy, establish reference intervals (RIs) for healthy pregnant women of Chinese population, and to provide an effective and reliable reference for clinicians.@*METHODS@#A total of 492 healthy pregnant women, who underwent pregnancy examination and delivery in the Department of Obstetrics, Second Xiangya Hospital of Central South University from October 2019 to October 2020, were enrolled for this study. They were assigned into the first trimester group, the second trimester group, the third trimester group, and the puerperium group according to the pregnancy period, and 123 healthy non-pregnant women were selected as the controls. Plasma levels of TM, TAT, PIC and tPAI-C were analyzed by automatic chemiluminescence immunoassay analyzer. The RIs for TM, TAT, PIC, and tPAI-C were defined using non-parametric 95% intervals, determined following Clinical and Laboratory Standards Institute Document C28-A3c (CLSI C28-A3c), and Formulation of Reference Intervals for the Clinical Laboratory Test Items (WS/T402-2012).@*RESULTS@#TM and TAT levels increased gradually in the first, second, and third trimester women and decreased in the puerperium women (P<0.05 or P<0.01). PIC level of healthy non-pregnant women was lower than that of pregnant women (P<0.05 or P<0.01), but PIC level of pregnant and puerperium women did not differ significantly (P>0.05). tPAI-C level in healthy non-pregnant women was lower than that of pregnant women (P<0.05 or P<0.01), and tPAI-C level was significantly decreases in the puerperium women (P<0.01). The RIs for TM were as follows: Healthy non-pregnant women at 3.20-4.60 TU/mL, the first and second trimester at 3.12-7.90 TU/mL, the third trimester at 3.42-8.29 TU/mL, puerperium at 2.70-6.40 TU/mL. The RIs for TAT were as follows: Healthy non-pregnant women at 0.50-1.64 ng/mL, the first and second trimester at 0.52-6.91 ng/mL, the third trimester at 0.96-12.92 ng/mL, puerperium at 0.82-3.75 ng/mL. The RIs for PIC were as follows: Healthy non-pregnant women at 0.160-0.519 ng/mL, pregnant women at 0.162-0.770 μg/mL. The RIs for tPAI-C were as follows: Healthy non-pregnant women at 1.90-4.80 ng/mL, the first and second trimester at 2.03-9.33 ng/mL, the third trimester at 2.80-14.20 ng/mL, puerperium at 1.10-8.40 ng/mL.@*CONCLUSIONS@#The levels of 4 new coagulation markers TM, TAT, PIC, and tPAI-C in pregnant women are increased significantly during pregnancy and gradually return to normal after delivery. The RIs for TM, TAT, PIC, and tPAI-C in pregnant women by trimester are established according to CLSI C28-A3c, thus providing a clinical reference for clinician in judgement of thrombotic risk.

ABSTRACT

Objectives: To analyze the association of inflammatory and coagulation biomarkers with mortality in geriatric patients with COVID-19. Methods: This is a retrospective cohort study of 206 patients aged 60 years or older who were hospitalized with COVID-19 at an intensive care unit. The analyzed variables were age, sex, length of hospital stay, and inflammatory biomarkers (C-reactive protein, neutrophil-to-lymphocyte ratio, procalcitonin, fibrinogen, ferritin, and d-dimer). We constructed a receiver operating characteristic curve and analyzed the area under the curve to evaluate the accuracy of biomarkers associated with mortality in patients with COVID-19. Results: Mean age was 72 (± 8) years. There were 101 deaths (49% of the total sample), which were significantly more frequent (p = 0.006) in the older age groups and were distributed as follows: 37.50% (60 ­ 69 years old); 50% (70 ­ 79 years old); 67.50% (80 ­ 89 years old); and 75% (over 90 years old). Mortality was associated with increased serum levels of procalcitonin, neutrophil-to-lymphocyte ratio, C-reactive protein, and d-dimer, and decreased fibrinogen levels. Neutrophil-to-lymphocyte ratio occupied the largest area under the receiver operating characteristic curve (area under the curve 0.859) in this group. Conclusions: In this study, inflammatory biomarkers neutrophil-to-lymphocyte ratio, procalcitonin, C-reactive protein, and d-dimer were associated with mortality in older patients with COVID-19 hospitalized at an intensive care unit, and neutrophil-to-lymphocyte ratio presented the best accuracy.


Objetivos: Analisar associação de biomarcadores inflamatórios e da coagulação com mortalidade em pacientes geriátricos com COVID-19. Metodologia: Estudo do tipo coorte retrospectiva de 206 pacientes com 60 anos de idade ou mais internados em unidade de terapia intensiva (UTI) com COVID-19. As variáveis analisadas foram idade, sexo, tempo de permanência hospitalar e biomarcadores inflamatórios, sendo esses proteína C reativa (PCR), relação neutrófilo-linfócitos (RNL), procalcitonina, fibrinogênio, ferritina e D-dímero. Empregou-se a curva ROC, com análise da área sob a curva (ACR), para avaliar a acurácia dos biomarcadores associados à mortalidade nos pacientes com COVID-19. Resultados: A média de idade foi de 72 (± 8) anos. Ocorreram 101 óbitos (49,02% da amostra total), significativamente mais frequente (p = 0,006) nas faixas etárias mais elevadas, distribuídos por faixa etária: 37,50% (60 ­ 69 anos); 50% (70 ­ 79 anos); 67,50% (80 ­ 89 anos); e 75% (nos maiores de 90 anos). A mortalidade foi associada a aumento dos níveis séricos dos biomarcadores procalcitonina, relação neutrófiloslinfócitos (RNL), proteína C reativa (PCR) e D-dímero, bem como diminuição dos níveis de fibrinogênio. A RNL ocupou a maior área sob a curva ROC (ACR 0,859) nesse grupo. Conclusões: Neste estudo, os biomarcadores inflamatórios RNL, procalcitonina, PCR e D-dímero foram associados com mortalidade em pacientes idosos portadores de COVID-19 internados em UTI, e a RNL foi a que apresentou a melhor acurácia.

ABSTRACT

El hiperaldosteronismo primario (HAP) es la causa más común de hipertensión arterial secundaria. A pesar de la prevalencia del HAP (6-10%) y sus consecuencias, los mecanismos que median los efectos deletéreos renales y extrarenales originados por la aldosterona más allá de la hipertensión arterial (ej. inflamación renal, alteraciones cardiacas y disfunción vascular), siguen siendo poco conocidos. Estudios previos sugieren que el exceso de aldosterona aumentaría proteínas sensibles a la activación del receptor de mineralocorticoides (MR), como las lipocalinas LCN2 (NGAL) y ORM1. OBJETIVO: Determinar la concentración de las lipocalinas ORM1, NGAL y NGAL-MMP9 en sujetos HAP. SUJETOS Y MÉTODOS: Estudio de cohorte transversal en sujetos adultos (similares en sexo, edad e IMC) separados en controles normotensos (CTL), hipertensos esenciales (HE) y con screening positivo de HAP (aldosterona ≥9 ng/dL y ARP < 1 ng/mL*h acorde a las guías internacionales de HAP). Se determinó la presión arterial sistólica (PAS) y diastólica (PAD), aldosterona plasmática, actividad renina plasmática (ARP) y la relación aldosterona / actividad de renina plasmática (ARR). Se determinó la concentración de NGAL, NGAL-MMP9 y ORM1 en suero por ELISA. RESULTADOS: Detectamos mayores niveles de ORM1 en sujetos HAP. No se detectaron diferencias en NGAL ni NGAL-MMP9 entre los grupos. Detectamos una asociación positiva de ORM1 con ARP (rho= -0,407, p=0,012) y con ARR (rho= 0,380 p= 0,021). CONCLUSIÓN: La mayor concentración de ORM1 en sujetos HAP y las asociaciones de ORM1 con aldosterona, ARP y ARR, proponen a esta proteína como un potencial biomarcador de HAP y de utilidad en el desarrollo de algoritmos diagnósticos de HAP.


Primary hyperaldosteronism (PA) is the most common cause of secondary hypertension. Despite the prevalence of PA (6-10%) and its consequences, the mechanisms that mediate the deleterious renal and extrarenal effects caused by aldosterone beyond arterial hypertension (eg renal inflammation, cardiac alterations and vascular dysfunction), remain barely known. Previous studies suggest that excess aldosterone would increase proteins sensitive to activation of the mineralocorticoid receptor (MR), such as lipocalins LCN2 (NGAL) and ORM1. AIM: To determine the concentration of the lipocalins ORM1, NGAL and NGAL-MMP9 in PA subjects. SUBJECTS AND METHODS: Cross-sectional study in adult subjects (similar in sex, age and BMI) grouped as normotensive controls (CTL), essential hypertensive (HE) and subjects with positive PA screening (aldosterone ≥ 9 ng/dL and PRA <1 ng/mL*h, according to international PA guidelines). Systolic (SBP) and diastolic (DBP) blood pressure, plasma aldosterone, plasma renin activity (PRA), and plasma aldosterone renin ratio (ARR) were determined. The concentration of NGAL, NGAL-MMP9 and ORM1 in serum was determined by ELISA. RESULTS: We detected higher levels Recibido: 03-09-2021 of ORM1 in PA subjects. No differences in NGAL or NGAL-MMP9 were detected between the groups. We detected a positive association of ORM1 with ARP (rho = -0.407, p < 0.05) and with ARR (rho = 0.380 p <0.05). CONCLUSION: The high levels of ORM1 in PA subjects and the associations of ORM1 with aldosterone, ARP and ARR, suggest ORM1 is a potential biomarker of PA, and useful in the development of a diagnostic algorithm for PA.

ABSTRACT Objective To identify the main risk factors for metabolic syndrome and its relationship with the perception of quality of life in Brazilian fishing colonies. Methods We included 77 participants aged > 18 years. Metabolic syndrome and quality of life were the main study outcomes. We considered a significance level < 0.05 and all procedures were approved by the ethics committee. Results Most participants are male, single, economic class D-E, working hours of 6 to 8 hours, length of service from 1 to 5 years, and dedicated exclusively to fishing. Conclusion Abdominal perimeter and blood pressures were the most frequent criteria and the greatest contribution to metabolic syndrome. Although quality of life had a higher score for the social relationship domain, in this study, the physical domain was the only one associated with another observation, in which we observed a significant correlation with systolic blood pressure.

ABSTRACT

ABSTRACT Objective: To investigate the effects of an interdisciplinary intervention on biomarkers of inflammation and their relationship with fibroblast growth factor 21 (FGF21) concentrations in women with overweight and obesity. Subjects and methods: Thirty-one women were enrolled in a 12-week interdisciplinary weight loss program delivered by a team comprising an endocrinologist, nutritionist and exercise physiologist. Body composition; anthropometric measures; metabolic and inflammatory markers including adiponectin, leptin, and atrial natriuretic peptide (ANP) were assessed at baseline and post-therapy. The homeostasis model assessment of insulin resistance (HOMA-IR) and the homeostasis model assessment of adiponectin (HOMA-AD) were calculated. The participants were divided into two groups: those with increased FGF21, and those with decreased FGF21. Results: The sample comprised women aged 32 ± 5 years with a body mass index of 33.64 ± 3.49 kg/m2. Body weight, waist circumference and leptin concentration were decreased in the whole sample after therapy. However, only the group with an increase in FGF21 concentration presented significant improvements in adiponectin concentration and adiponectin/leptin ratio. Moreover, although there was a reduction of leptin in both groups, it was greater in the increased FGF21 groups. There was a reduction in ANP in the decreased FGF21 group. Conclusions: Changes in FGF21 concentrations were different among the women participating in the weight loss program, with some having increased levels and some reduced levels. Furthermore, improvements in adiponectin and the adiponectin/leptin ratio were found only in the group with increased FGF21 concentration.

ABSTRACT

INTRODUCCIÓN. La enfermedad relacionada con IgG4 es una patología fibroinflamatoria multiorgánica, de origen desconocido, que simula trastornos malignos, infecciosos e inflamatorios. Los criterios del American College of Rheumatology y la European League against Rheumatism 2019, son útiles para el diagnóstico diferencial de ésta enfermedad cuando se no se cuenta con evidencia de inmunoglobulina G4 en sangre. CASO CLÍNICO. Paciente hombre de 45 años de edad, nacido en Ambato-Ecuador, con ingreso en noviembre del 2017, en emergencias del Hospital de Especialidades Carlos Andrade Marín, con presencia de tos con hemoptisis leve, febrícula, astenia, pérdida de peso e hiporexia de dos semanas de evolución. Se realizó múltiples exámenes, tras observar infiltrados pulmonares intersticiales, con elevación de inmunoglobulina G en suero, negativas para malignidad; se sospechó de enfermedad relacionada a inmunoglobulina G4. Se ampliaron los estudios para descartar otras patologías más prevalentes y cuyo diferencial es primordial. Se inició tratamiento con prednisona y micofenolato con buena respuesta clínica; durante dos años. DISCUSIÓN. La evidencia científica registró que el hallazgo más importante en la enfermedad relacionada con inmunoglobulina G4 fue un aumento de sus niveles séricos. La recurrencia de la enfermedad en un órgano afectado o la aparición de un nuevo órgano involucrado pudo conducir al diagnóstico en el caso presentado. CONCLUSIÓN. La enfermedad relacionada con inmunoglobulina G4 al ser una patología heterogénea, inmunomediada, al simular otras afecciones puede retrasar el diagnóstico; se debe tener una alta sospecha clínica, si al excluir otros procesos infecciosos, autoinmunes y/o eoplásicos, hay evidencia de patología fibroesclerosante multiorgánica sin causa establecida.


INTRODUCTION. IgG4-related disease is a multiorgan fibroinflammatory pathology of unknown origin that mimics malignant, infectious, and inflammatory disorders. The criteria of the American College of Rheumatology and the European League against Rheumatism 2019 are useful for the differential diagnosis of this disease when there is no evidence of immunoglobulin G4 in blood. CLINICAL CASE. 45-year-old male patient, born in Ambato-Ecuador, with admission in November 2017, in the emergency room of the Hospital de Especialidades Carlos Andrade Marín, with the presence of cough with mild hemoptysis, fever, asthenia, weight loss and hyporexia of two weeks of evolution. Multiple tests were performed, after observing interstitial pulmonary infiltrates, with elevated serum immunoglobulin G, negative for malignancy; immunoglobulin G4-related disease was suspected. Studies were extended to rule out other more prevalent pathologies whose differential is paramount. Treatment with prednisone and mycophenolate was started with good clinical response; for two years. DISCUSSION. The scientific evidence recorded that the most important finding in immunoglobulin G4-related disease was an increase in its serum levels. Recurrence of the disease in an affected organ or the appearance of a new involved organ could have led to the diagnosis in the presented case. CONCLUSION. Immunoglobulin G4-related disease, being a heterogeneous, immune-mediated pathology, by simulating other conditions may delay diagnosis; a high clinical suspicion should be maintained if, when other infectious, autoimmune and/or neoplastic processes are excluded, there is evidence of multiorgan fibrosclerosing pathology without established cause.

ABSTRACT

Abstract Background The analysis of the atherogenic potential of the lipid profile for biomarkers, such as the TG/HDL-c ratio, predicts cardiovascular risk better than isolated lipids. Objective To identify the TG/HDL-c cutoff points for multiple risks (hypertension, Diabetes Mellitus, obesity) and to evaluate the association between sociodemographic, clinical, laboratory, anthropometric, and life habit variables and the TG/HDL-c ratio in hypertensive and/or diabetic individuals in the context of Primary Health Care. Methods This was a cross-sectional study with 833 hypertensive and/or diabetic patients, conducted between August 2017 and April 2018. The cutoff point of the TG/HDL-c were obtained by the ROC curve. Cardiovascular risk was discriminated by TG/HDL-c, categorized by the cutoff and evaluated in relation to multiple risks. The magnitude of the association between TG/HDL-c and independent variables was estimated by logistic regression. The significance level of p<0.05 was adopted for all tests. Results The cutoff values of TG/HDL-c (3.26 for men and 2.72 for women) were more sensitive and less specific than those in the literature. Women (OR=1.90 and 95% CI 1.13-3.20) and men (OR=4.58 and 95% CI 1.78-11.76) with multiple risks, and white men, alcohol users, with a history of stroke, had a higher chance of altered GT/HDL-c. Increases in glycosylated hemoglobin, glycemia, and phosphorus in women, and cholesterol, glycemia, and microalbuminuria in men increased the chances of altered TG/HDL-c. Being a former smoker and black reduced the chance of altered TG/HDL-c in women. Conclusions TG/HDL-c proved to be a good indicator for habitual use in Primary Care.

ABSTRACT

Hematological and serum biochemical characteristics and prevalence of microorganisms in the uterine content of bitches with pyometra were described, according to type and age. This study was carried out at the Veterinary Medicine Hospital Renato Rodenburg de Medeiros Netto of the UFBA with 132 patients diagnosed with pyometra through imaging and laboratory tests, divided into two groups: Group 1 - less than eight years (n=72) and Group 2 - more than eight years (n=60). Both groups were submitted to Ovariohysterectomy (OH), in which blood and uterine lumen secretion samples were collected. The highest incidence of pyometra was found in bitches under 8 years (54.5%), Poodle breed (31.8%) and mixed-breed (27.3%). Open pyometra represented 80.3% of all cases. The death rate (6.0%) did not show significant difference between the types. Anemia (73.0%), thrombocytopenia (41.2%) and leukocytosis (77.0%) were observed. Urea and ALP were above the reference values in 41.8% and 52.2% of each group, respectively, while ALT (94.0%) and creatine (82%) remained normal in most animals. Serum biochemistry did not show significant differences (P<0.05). Escherichia coli and Klebsiella sp. grew in 33.3% and 16.7% of the samples, respectively. Therefore, no significant hematological and serum biochemical differences were observed in bitches with pyometra in both age categories.


Descreveu-se características hematológicas, bioquímicas séricas e prevalência de microrganismos no conteúdo uterino de cadelas com piometra, de acordo com o tipo e idade. Realizou-se este estudo no Hospital de Medicina Veterinária Renato Rodenburg de Medeiros Netto da UFBA com 132 pacientes diagnosticadas com piometra, por exames de imagem e laboratoriais, divididas em dois grupos: Grupo 1 – menos de oito anos (n=72) e Grupo 2 – mais de oito anos (n=60), submetidas a Ovariectomia (OH), quando se coletou amostras de sangue e secreção do lúmen uterino. A incidência maior deu-se em cadelas abaixo de 8 anos (54,5%), da raça Poodle (31,8%) e sem raça definida (SRD) (27,3%), sendo 80,3% de piometra aberta. A taxa de óbito (6,0%) não apresentou diferença significativa entre os tipos. Observou-se a ocorrência de anemia (73,0%), trombocitopenia (41,2%) e leucocitose (77,0%). Os valores de ureia e FA estiveram acima dos valores de referência em 41,8% e 52,2% das cadelas respectivamente, enquanto a ALT (94,0%) e a creatina (82%) mantiveram-se dentro dos valores de referência na maioria dos animais. A bioquímica sérica não apresentou diferenças significativas (P<0,05). Observou-se crescimento de Escherichia coli e Klebsiella sp. em 33,3% e 16,7% das amostras, respectivamente. Sendo assim, não se observou diferenças significativas hematológicas e na bioquímica sérica de cadelas com piometra nas categorias de idade.

ABSTRACT

Marcadores sorológicos são rotineiramente utilizados na prática clínica para o estadiamento de linfomas e para a determinação de seu prognóstico em humanos. No entanto, pouco se sabe sobre sua utilização em cães, mesmo os linfomas sendo neoplasias com alta prevalência nessa espécie. No presente estudo, as concentrações séricas do receptor solúvel de interleucina-2 (sIL-2R) e do antígeno do câncer 125 (CA 125) foram mensurados em 10 cães saudáveis e em 15 cães com linfoma cutâneo, utilizando-se o kit ELISA canino e a leitura em um Stat Fax modelo 2100 (sIL-2R), bem como o kit ELISA humano e a leitura pelo ELISYS UNO humano (CA 125). Os resultados mostraram que não houve diferença significativa (P<0,05) nas concentrações dos marcadores entre os grupos. Além disso, os resultados não apontaram significância clínica no estadiamento tumoral e estabelecimento do prognóstico em cães diagnosticados com linfoma cutâneo.(AU)
