ABSTRACT
Objective:To study the predictive value of total serum bilirubin (TSB) and the ratio of bilirubin to albumin (B/A) in neonatal acute bilirubin encephalopathy (ABE).Methods:Neonates with extremely severe hyperbilirubinemia (TSB≥425 μmol/L) treated in the Nanjing Maternal and Child Health Hospital, Maternity and Child Health Care of Guangxi Zhuang Autonomous Region, Northwest Women and Children's Hospital, Yinchuan Maternal and Child Health Hospital and Liaocheng People's Hospital from March 2018 to August 2019 were selected as prospective subjects for this study. According to the score of brain injury induced by bilirubin, the subjects were divided into ABE group and non-ABE group, and the predictive value of TSB peak and B/A for neonatal ABE were analyzed.Results:A total of 194 infants with extremely severe hyperbilirubinemia were recruited in this study, including 20 in ABE group and 174 in non-ABE group. The peak value of bilirubin ranged from 427 to 979 μmol/L. The optimal critical values of TSB peak value and B/A for ABE prediction were 530 μmol/L and 9.48, respectively. The sensitivity and specificity of ABE prediction were 85.0% and 92.8% when combined with TSB peak and B/A values.Conclusions:TSB peak combined with B/A value can effectively identify neonatal ABE. When the TSB peak value was greater than 530 μmol/L and the B/A value was greater than 9.48, the neonates had a higher risk of neonatal ABE.

ABSTRACT
Objective:To study the correlation between transcutaneous bilirubin (TcB) level measured from shielded skin and total serum bilirubin (TSB) level after phototherapy in premature infants.Methods:From July 2019 to July 2021,preterm infants with jaundice admitted to the Department of Neonatology of our hospital and received phototherapy were prospectively enrolled in the study. The infants were assigned into 26~31w group, 32~34w group and 35~36w group according to their gestational ages. During phototherapy, the forehead, the chest and the perineum were shielded. TcBs were measured at the above mentioned areas three times each before and after phototherapy and TSB was measured from venous blood samples.Results:A total of 306 premature infants were included, with 51 cases in 26~31w group, 126 cases in 32~34w group and 129 cases in 35~36w group. Before phototherapy, TcBs of the forehead, the chest and the perineum of all infants were correlated with TSB ( r=0.699, 0.913, 0.734, P<0.001) with TcB of the chest showed the best correlation. A linear regression equation was established using the TSB before phototherapy and the TcB of the chest: TSB=0.634+0.912TcB. After phototherapy, TcBs of the forehead, the chest and the perineum of all infants were also correlated with TSB ( r=0.586, 0.879, 0.690, P<0.001) with TcB of the chest showed the best correlation and the linear regression equation was TSB=1.910+0.736TcB. Conclusions:For preterm infants with gestational age of 26~36w, TcB of the shielded chest skin after phototherapy is correlated with TSB and a linear regression model can be established.
ABSTRACT
Objective To investigate the correlation between smoking, white blood cell counts, and serum bilirubin levels in male radiation workers, and to explore the role of systemic inflammatory response in the changes of serum bilirubin level induced by smoking. Methods Occupational health examination data of 1 320 male radiation workers in a medical institution was collected. Linear regression analysis method was used to analyze the correlations between smoking and white blood cell counts, between smoking and serum bilirubin levels, and between white blood cell counts and serum bilirubin levels. Results There was a significant positive correlation between smoking and white blood cell counts (P 0.05). By dividing white blood cell counts into two groups, an inverse correlation was found between smoking and serum bilirubin levels in the high white blood cell count group (P < 0.05). Conclusion Serum bilirubin may be an effective indicator of early health damage caused by smoking in male radiation workers. Smoking may induce inflammatory reaction, thus deplete serum bilirubin and cause its levels to drop.
ABSTRACT
Objective:To study the predictive value of hour-specific total serum bilirubin(TSB) nomogram combined with clinical risk factors in the risk of hyperbilirubinemia.Method:Perinatal clinical data of newborns born in Shanghai Pudong New Area Health Care Hospital for Women and Children, Shanghai Pudong New Area People's Hospital and Shanghai Pudong Hospital from August 2017 to July 2018 were collected in this prospective study. Transcutaneous bilirubin (TcB) was monitored before discharge from hospital. Enrolled neonates were followed up for 28 days. The patients were assigned to neonatal hyperbilirubinemia group (NHB) and non-hyperbilirubinemia group (Non-HB) according to the occurrence of hyperbilirubinemia. The predictive value of models for the risk of hyperbilirubinemia was evaluated by receiver operating characteristic (ROC) curves and Logistic regression analysis.Result:A total of 8 664 newborns were included in this study, with 1 196 cases of hyperbilirubinemia, with an incidence of 13.8%. Logistic regression analysis showed that maternal blood type O, premature rupture of membranes, male gender, gestational age 35~37 weeks, subcutaneous ecchymosis/cranial edema, and breastfeeding were independent risk factors for NHB ( P<0.05). The area under receiver operative characteristic curve (ROC) of predischarge bilirubin risk zone only was 0.874(95% CI 0.861~0.885, P<0.05)and for all independent risk factors was 0.664 (95% CI 0.647~0.680, P<0.05). The area under ROC curve was 0.891 (95% CI 0.880~0.902, P<0.05) by combining predischarge bilirubin risk zone with clinical risk factors. Conclusion:Predischarge bilirubin risk zone combined with clinical risk factors can reasonably predict neonatal hyperbilirubinemia well.
ABSTRACT
Background: Malaria is a parasitic disease which is majorly caused by the bite of an infected Anopheles mosquito. It has been estimated that the most common type of malaria affecting the human race is known as Plasmodium vivax. Human malaria is a global burden with 3.4 billion people at risk over 91 endemic countries. According to the WHO, the involvement of liver dysfunction in Plasmodium vivax malaria is not an uncommon phenomenon. Aim of the research was to study various clinical manifestations and biochemical parameter for liver dysfunction in association with Plasmodium vivax malaria.Methods: It was an observational study carried out at Teerthanker Mahaveer Medical College and Research Centre, a tertiary care hospital situated in Moradabad for a period of 1 year (March 2017-Feb 2018). Total of 200 patients aged above 15 years, with either sex were part of it. All the patients having mixed malaria with dengue, pregnant women and the patients who did not give written consent for being a part of the study were excluded from the study. A detailed clinical examination was done, including all the hematological and biochemical examinations.Results: The results depicted that the number of male patients was 95, and the number of female patients was 105. The majority of the patients belonged to 15-30 years of age group. The major clinical features of the patients suffering from P. Vivax were fever and jaundice. The number of patients with serum bilirubin >3 mg/dl was 55.Conclusions: In light of the above results, it was evident that Plasmodium vivax has the capability of producing jaundice, hepatic dysfunction and anemia. The doctors must be very vigilant while treating the patients with Plasmodium vivax for any symptoms of jaundice as they are often misunderstood as hepatitis.
ABSTRACT
Background: NH affects nearly 60% of term and 80% of preterm neonates during first week of life. 6.1% of well term newborn have a serum bilirubin over 12.9 mg%. Serum bilirubin over 15 mg% is found in 3% of normal term newborns. Neonatal Hyperbilirubinemia (NH) is a cause of concern for the parents as well as for the paediatricians. Aim of study to find out the association between various levels of cord serum albumin (CSA) and significant neonatal hyperbilirubinemia requiring interventions like phototherapy or exchange transfusion and whether it can be used as a risk indicator for subsequent development of significant jaundice.Methods: The present study was conducted on 150 randomly selected eligible term neonates delivered at Department of Pediatrics, Rajkiya Mahila Chikitsalaya, JLN Medical College and Associated Group of Hospitals, Ajmer, India.Results: Authors conducted a prospective study on 150sequentially born term babies. Cord blood was collected at birth and cord serum albumin estimation was done within 4-6 hours of collection of the blood. Cohort was grouped into Group 1, Group 2 and Group 3 based on CSA level ≤ 2.8g/dl, 2.9-3.3g/dl and ≥ 3.4 g/dl respectively. Knowledge of risk factors of NH in neonates could influence decision of early discharge vs. prolonged observation cord serum albumin level of ≤ 2.8g/dl has a correlation with incidence of significant hyperbilirubinemia in term newborns. So this ≤ 2.8g/dl of cord serum albumin level can be used as risk indicator to predict the development of significant hyperbilirubinemia. Whereas cord serum albumin level ≥3.4g/dl is considered safe.Conclusions: Term neonates with hyperbilirubinemia with a total serum bilirubin level ≥17 mg/dl had levels of cord serum albumin of ≤ 2.8 g/dl, and this can be used as a risk indicator to predict the development of NH.
ABSTRACT
Background: Acute appendicitis is the commonest cause of acute surgical abdomen. Appendicectomy is the most frequently performed urgent abdominal operation and is often the first major procedure performed by a surgeon in training. Delay in diagnosis and treatment results in increased rate of perforation, morbidity, mortality and hospital stay.Methods: A prospective study where a total of 100 patients with clinical, radiological and histopathological diagnosis of acute appendicitis or appendicular perforation were studied. The liver function tests were carried out in all the patients.Results: In a study group of 100 patients (74 males and 26 females); 59 cases were acute appendicitis and 41 cases were appendiceal perforation proven histopathological. Out of which 48 cases had elevated serum bilirubin levels i.e., 17 in acute appendicitis group and 31 in appendicular perforation group. The mean serum total bilirubin is 1±0.4 in acute appendicitis cases and 1.9±1.13 in the appendicular perforation cases. Similarly, the sensitivity and specificity of elevated serum bilirubin as a diagnostic marker in appendicular perforation was found to be 75.6% and 71.2% respectively.Conclusions: Elevated serum bilirubin levels appears to be a promising new supplemental diagnostic serum marker in Appendicular Perforation and perhaps be a decision-making investigation.
ABSTRACT
Background: Jaundice is a very common neonatal problemand contributes a lot to the admission into neonatal care unitsand hospitals. Early estimation of TcB may help identifyingneonates with significant jaundice requiring serum bilirubinestimation. This may help avoiding unnecessary estimation ofserum bilirubin by invasive method in preterm and termneonates. TcB has been practised mostly in the whitepopulation and studies in the nonwhite population is relativelyscarce. In Bangladesh, estimation of TcB is a very newapproach and not in practice in most of the centres; andinvolves only term and near-term neonates sparing pretermones.Objective: To evaluate the correlation of transcutaneousbilirubin with serum bilirubin in term and preterm neonates withjaundice.Methods: This cross sectional study was conducted in thedepartment of Neonatology, Bangabandhu Sheikh MujibMedical University (BSMMU) from September 2015 to August2016. Jaundiced neonates ranging from 28 to 42 weeks ofgestation were studied. JM-103 device and DichlorophenylDiazonium method were used to measure TcB and TSBrespectively. TcB measurements were obtained over thesternum 30 minutes prior or after blood sampling for TSB.Pearson’s correlation coefficient and linear regression analysiswere used to determine the correlation between TcB and TSB.Bland-Altman plot was used to analyse the agreement betweenTcB and TSB. ROC curve was constructed both for term andpreterm infants to determine the best cut-off values with theirsensitivity and specificity.Results: A total of 148 paired TcB-TSB readings for 102jaundiced term and preterm infants were obtained. Correlationcoefficient in total population, term and preterm neonates were0.83, 0.92 and 0.69 respectively. Bland-Altman plot showedreasonable agreement in term newborns but not in pretermbabies. Overall best sensitivity and specificity of TcB in termneonates was 90% and 73%, and in preterm neonates 65%and 60% respectively. Area under the curve for TcB was 86%in term neonates, whereas it was 63% in preterm neonates.
ABSTRACT
Background: Neonatal hyperbilirubinemia, though benign in 80% cases, can lead to kernicterus if not diagnosed and treated early. The golden method of estimation is measuring serum bilirubin levels. Both Kramer's scale and Transcutaneous bilirubinometer are non -invasive methods. Its high time the pediatricians choose an ideal non-invasive and reliable method to detect hyperbilirubinemia. Objective of this study is to find out which has a better correlation with serum bilirubin - transcutaneous bilirubinometer reading (TcB) or Kramer's scale.Methods: The study was conducted in a tertiary newborn center from November 2014 to June 2016. The inclusion criteria included all babies above 34 weeks gestation and exclusion criteria included babies with established direct hyperbilirubinemia, neonatal septicemia, major congenital/ gastrointestinal malformations and those on phototherapy. The sample size was 450 and the correlation was analyzed using ROC curves and plots of agreement was done using Bland Altman charts.Results: The incidence of significant Hyperbilirubinemia is 12%. Transcutaneous bilirubin level had a better correlation and prediction level compared to Kramer at both 24 hours and 48 hours. Bland Altman analysis showed that transcutaneous values were closer to the total serum bilirubin level compared to Kramer values.Conclusion: Transcutaneous bilirubinometry is a better and more ideal choice to replace serum bilirubin levels. In settings where TcB is not feasible, it's always best to screen for jaundice using Kramer's scale rather than estimating serum bilirubin values in all babies. In babies where TcB levels are above the cut off range, it's better to do serum bilirubin levels.
ABSTRACT
Background: Infants who are clinically jaundiced in the first few days are more likely to develop hyperbilirubinemia. The present study was made attempt to evaluate the predictive value of serum bilirubin level on day one postnatal age for identifying term neonates at risk for subsequent hyperbilirubinemia.Method: The present hospital based prospective study involving neonate's ?37 weeks of gestational age included 200 healthy term newborn babies (?37weeks GA) born at GSL medical college and hospital at Rajahmundry during study period. The purpose of this study was explained to the parents/ guardian and written consent was taken prior to the study. Data collected was kept securely. Permission was obtained from the Ethical Committee of GSL medical College before starting the study.Result: Newborns who developed significant hyperbilirubinemia male: female ratio was 1.07:1. 9(33%) newborns with significant hyperbilirubinemia had jaundice in previous siblings. In the present study, the value of 4.9 mg/dl was determined to have the best combination of sensitivity and specificity to predict neonates at risk of hyper birubinemia subsequently. At this value of 4.9 mg/dl there is high sensitivity and a very high negative predictive value, although a low positive predictive value for predicting neonates likely to develop significant hyperbilirubinemia.Conclusion: Early screening and appropriate management of hyperbilirubinemia is needed for prevention of complications in the newborn. This decreases the significant burden of untreated severe neonatal jaundice, causing potential neurological sequelae. Prediction of neonatal hyperbilirubinemia has widespread implication especially in our country where there are limited resources.
ABSTRACT
Background: Hyperbilirubinemia is one of the common problems in neonates. The transcutaneous bilirubin (TCB) measurement is non-invasive, easy and rapid not requiring expertise and manpower. Fewer studies have been carried out to whether newer TCB measurements can correlate with serum bilirubin measurements using newer generation of transcutaneous bilirubinometer in our region.Methods: An observational cross-sectional study to compare serum and transcutaneous bilirubin measurements in newborns admitted to a neonatal intensive care unit, conducted from December 2015 to November 2017. Blood samples were obtained from neonates collected from venous sample into plain bulb and sent for analysis. For transcutaneous bilirubin measurement, the reading from forehead and sternum were taken using bilirubinometer and an average reading was taken for comparison.Results: Total 172 neonates were admitted during study period and enrolled in the study. It was observed that out of 172 patients, studied 102(59%) patients were male and 70(41%) patients were female. Out of 172 patients maximum 89(51.74%) mother have O positive blood group and only 2(1.1%) have O negative blood group. Common cause of neonatal hyperbilirubinemia was ABO incompatibility 81(48%), Rh incompatibility 11(6%), and other causes 80(46%). The mean and standard deviation of TSB for first, second and third reading were 19.21'3.44, 15.76'2.79 and 12.89'2.44 respectively. While mean and standard deviation of TCB for first, second and third reading were 18.34'2.99, 15.48'2.36 and 12.31'2.28 respectively with correlation coefficient of r=0.806513, r=0.694273, r=0.785471 respectively indicating linear relationship between two.Conclusions: There was a strong correlation between serum and transcutaneous bilirubin levels before and even after the phototherapy. As transcutaneous bilirubin estimation is non-invasive, gives quick and reproducible results. So, by using this method has potential screening value especially in the high-risk neonates to start early intervention.
ABSTRACT
Introducción: Las pautas para prevención y tratamiento de hiperbilirrubinemia neonatal recomiendan medición de bilirrubina sérica total (BST) o bilirrubina transcutánea (BTc) para determinar el grado de ictericia antes del alta del recién nacido (RN); ésta última no invasiva, proporciona información instantánea y de calidad superior a la evaluación clínica. A pesar de ello aún no ha sido aplicada en forma sistemática en los hospitales de Paraguay. Objetivo: evaluar la aplicación en nuestro medio de la medición de bilirrubinemia transcutánea antes del alta correlancionando con la bilirrubina sérica. Materiales y Métodos: Estudio observacional, descriptivo con componente analítico, de corte transversal. Fueron incluidos RN con edad gestacional ≥ a 35 semanas, con peso ≥ a 2000 gramos, luego de las 24 hs de vida hasta los 8 días; bajo consentimiento informado de los padres, durante un año. Los datos fueron consignados en una planilla de Microsoft Excel y procesado por el software IBM SPSS Statistics ®. Resultados: De 271 RN que ingresaron al estudio, en la primera medición con el Bilirrubinómetro transcutáneo, cumplían con criterios para toma de bilirrubina sérica 90 (33,2%) de ellos. En los restantes 181 RN (66,8%), los datos emparejados no estaban disponibles debido a que siguiendo las recomendaciones de las guías actuales no fue necesario medir la bilirrubina sérica. El valor del coeficiente de correlación para la primera medición fue r = 0.574. Para la segunda medición las medidas emparejadas estaban disponibles para 131 RN. En este caso se encontró correlación positiva entre ambos métodos de 0,590. Conclusión: La bilirrubina transcutánea puede utilizarse en forma rápida, segura y válida, como un test de screening para la detección de hiperbilirrubinemia y podría evitar una proporción importante de toma de muestras sanguíneas, mejorando la seguridad del paciente.
Introduction: The guidelines for prevention and treatment of neonatal hyperbilirubinemia recommend measurement of total serum bilirubin (BST) or transcutaneous bilirubin (BTc) to determine the degree of jaundice before discharge of the newborn (NB); the latter non-invasive method provides instant information which is superior to the clinical evaluation. Despite this, it has not yet been systematically applied in hospitals in Paraguay. Objective: to evaluate transcutaneous measurement of bilirubin concentration as compared to serum bilirubin levels prior to discharge in our setting. Materials and Methods: This was an observational, cross-sectional, descriptive study with an analytical component. For a period of one year, we tracked NBs with a gestational age ≥ 35 weeks, weighing ≥ 2000 grams, from 24 hours of life until 8 days of life, obtaining the informed consent of the parents. The data was entered in a Microsoft Excel spreadsheet and processed by the IBM SPSS Statistics ® software. Results: Of 271 NBs who entered the study, 90 (33.2%) met criteria for measurement of serum bilirubin at their first measurement with the transcutaneous bilirubinometer. In the remaining 181 RN (66.8%), the paired data were not available as measurement of serum bilirubin was not required per the recommendations of current guidelines. The correlation coefficient value for the first measurement was r = 0.574. For the second measurement, paired measurements were available for 131 NBs. In this case, a positive correlation was found between both methods of 0.590. Conclusion: Transcutaneous bilirubin can be used quickly, safely and accurately as a screening test for the detection of hyperbilirubinemia and could avoid a significant proportion of blood sampling, improving patient safety.

OBJECTIVE: To analyze the relationship between clinical characteristics and postoperative complications in patients with hilar cholangiocarcinoma(HCCA) who underwent major liver resection(MLR).METHODS: Clinical characteristics and postoperative complications of 335 patients with HCCA who underwent MLR from January 2010 to October 2017 were retrospectively analyzed.According to the severity of complications,the patients were divided into two groups:low clavien-dindo group(LCD)and high clavien-dindo group(HCD).RESULTS: There were 219 patients in LCD group and 116 patients in HCD group.Elevated INR,Bismuth Ⅲa/Ⅳ type and the right liver/expanding right/right trilobites resection were high risk factors of postoperative serious complications.The incidence of severe postoperative complications in the group with preoperative biliary drainage was 34.18%(67/196),which was not statistically significant different from that in the group without preoperative biliary drainage [35.25%(49/139),P=0.8396].The dose-response curve and Logistic regression indicated that there was a statistical difference in postoperative complication risk between patients with total bilirubin(TB)<140 mol/L and patients with TB≥ 140 mol/L(OR=1.917,95% CI 1.147～3.203,P=0.0130).After statistical correction,the statistical correlation remained,among which,the preoperative biliary drainage rate was 59.2%(151/255) in the group with TB<140 mol/L,and 56.3%(45/80)in the group with TB≥ 140 mol/L.CONCLUSION: In patients with HCCA combined with MLR,patients with TB ≥ 140 mol/L should be routinely treated with preoperative biliary drainage.Especially for the right liver resection,preoperative high INR patients,more attention should be paid to.METHODS: of preoperative biliary drainage have no significant effect on the overall postoperative complications and can be flexibly selected according to the needs of the disease.
ABSTRACT
Bilirubin encephalopathy is still one of the challenges for neonatal society.In recent years,the incidence in Europe and North America is 1/100 000 ～ 1/40 000,while it is 1.13‰ in China.The current guideline for neonatal hyperbilirubinemia is based on total serum bilirubin (TSB),combined with gestational age,birth weight,age and risk factors.TSB is used as a main index for phototherapy and exchange transfusion.However,only unbound serum bilirubin (UB) can cross blood brain barrier and neuron membrane to cause neurotoxicity,so it is important to monitor UB.In view of the difficulties to measure UB directly,it has been proposed to measure serum albumin (SA),the TSB/SA ratio,TSB/SA molar ratio and the affinity of SA for TSB in addition to monitor TSB,but their clinical practice value is limited.Previously,the methods for direct detection of UB such as oxidase method,modified peroxidase method and photometric method have not been accepted nor routinely used.Recently Martelanc has piloted to use high performance liquid chromatography to directly measure UB with precision up to pmol/L.This recent progress offers reference for measuring UB in neonates,but the threshold of UB predicting bilirubin encephalopathy needs to be further studied.This article will review the important role of UB in predicting bilirubin encephalopathy,predicting experimental parameters of neonatal bilirubin encephalopathy,current methodologies for direct detection of UB.
ABSTRACT
BACKGROUND@#Timely initiation of therapy for neonatal hyperbilirubinemia is routinely made based on total serum bilirubin levels. However, serial samplings by invasive needle pricks are needed for laboratory analyses. Studies comparing the correlation between serum bilirubin and transcutaneous bilirubin have yielded diverse results. A meta- analysis was done to find out the relationship between transcutaneous bilirubin measurements and serum bilirubin values.@*OBJECTIVE@#This study aims to analyze scientific articles regarding the accuracy of transcutaneous bilirubin measurements among healthy neonates as an alternative screening for hyperbilirubinemia.@*STUDY DESIGN@#Diagnostic Accuracy meta- analysis.@*METHODS@#Studies on the accuracy of transcutaneous bilirubin measurements were identified through intensive literature search. Local studies were confirmed thru personal communication.@*RESULTS@#Three hundred eighteen studies were identified through literature search. Ten studies met the eligibility criteria. Eight of the ten studies reported results as correlation coefficients. The pooled estimates of correlation coefficients is high at r = 0.85 (95% CI = 0.84 to 0.857). Five studies reported results with data for diagnostic accuracy. The pooled analysis for sensitivity and specificity are high at 0.84 (95% CI 0.8-0.88) and 0.79 (95% CI 0.77-0.81) respectively. The pooled likelihood ratio has a significant difference with a pooled positive LR of 4.19 (95% CI 2.98-5.9, P<0.01) while the negative likelihood ratio is 0.23 (95% CI: 0.17 to 0.29). The AUC for transcutaneous bilirubinometry is 0.89.@*CONCLUSIONS@#Transcutaneous bilirubin measurement can be an alternative in monitoring the risk of healthy neonates for hyperbilirubinemia based on the pooled analysis of correlation coefficient and diagnostic accuracy.
ABSTRACT
Background: The protective effect of bilirubin relates to the antioxidant property of bilirubin, which prevents lipid oxidation, especially low-density lipoprotein (LDL), and inhibits free radical-induced dam-ages. Lower serum bilirubin level has been proven to be associated with endothelium and microvascular malfunction. The aim of the present study was to assess the association between serum bilirubin levels and coronary artery disease in comparison with controls without coronary artery disease.Methods: A cross-sectional study was conducted for a period of a one year in our medical college hospital. Patients with evidence of coronary artery disease for not more than 10 years of duration confirmed by ECG, ECHO and other previous case records were taken as cases. Controls were selected matched with age, gender and other co-morbid conditions. Total of 200 subjects were included in the study with 100 cases and 100 controls. General and systemic examination was conducted on all study subjects including laboratory investigations like complete blood count, renal function test, lipid profile, viral markers such as HBsAG, HCVIgM and liver function test which includes total bilirubin, direct and indirect, liver enzymes, albumin and globulin levels. A 12 lead ECG and a transthoracic echocardiogram was performed for all patients.Results: The various liver function test parameters were compared between the cases and controls it was found that the serum bilirubin levels which includes total bilirubin, direct bilirubin and indirect bilirubin was found to be lower among the case group compared to the control group and this difference was found to be statistically significant (p <0.05). A perfect linear correlation between the ejection fraction and serum bilirubin levels, as the ejection fraction decreases the serum bilirubin levels was also decreasing.Conclusions: This study showed a significant association between the reduced serum bilirubin levels and the occurrence of CAD; therefore, bilirubin level can serve as a predictive factor, together with other influential factors for identifying a person at risk of developing coronary artery disease.
ABSTRACT
Background: Hypertension is one of the known cardiovascular risk factors. Several epidemiological studies have found an association between various anthropometric indicators and hypertension. The present study was conducted to investigate the relationship between different commonly and uncommonly used anthropometric parameters, various biochemical parameters and hypertension in adults.Methods: A hospital based cross sectional study conducted among 300 adults aged 40 years and more, attending Medicine OPD of a tertiary care institution after obtaining their consent and permission from institutional ethical committee. Anthropometric measurements, blood pressure examination and relevant laboratory investigations were done.Results: Hypertension was seen in both obese and non-obese study subjects. BMI, waist circumference, neck circumference, sagittal abdominal diameter and CRP was higher in hypertensive males than normotensives and it was statistically significant. BMI, waist circumference, hip circumference, neck circumference, sagittal abdominal diameter and CRP had a positive correlation with systolic and diastolic blood pressure and it was found to be statistically significant.Conclusions: CRP, serum ferritin, sagittal abdominal diameter, hip circumference, waist circumference and neck circumference showed a positive correlation with both systolic and diastolic blood pressure, which means that WC and SAD can be used to get information about visceral obesity in an individual. This also suggests that decrease in intra-abdominal fat could decrease the blood pressure.
ABSTRACT
Background: Cardiovascular risk factors for ACS are on the rise in people of Indian origin and ACS is now the leading cause of death. More recent evidence suggests that bilirubin is a potent physiological antioxidant that may provide important protection against atherosclerosis and inflammation. Substantial evidence has documented that the development of CAD involves lipid oxidation and formation of oxygen radicals as atherosclerosis and inflammation are associated with formation of oxygen and peroxyl radicals. Keep of these points in mind, the present study was undertaken to find relation between Serum Bilirubin and Acute Coronary Syndrome.Methods: The present descriptive cross-sectional study conducted at A.J Institute of Medical Sciences and Research Centre, Mangaluru from October 2016 to April 2017. A detailed history, general physical examination, systemic examination and investigations was performed on all patients who fulfill the inclusion criterion and age >18yrs, both sexes who are admitted in CCU.Results: Hypertension had statistically significant correlation with ACS. All risk factors were more associated with STEMI compared to unstable angina or NSTEMI. On Correlation of LDL and Total leucocyte count with bilirubin both were statistically significant when compared to bilirubin levels.Conclusions: The study showed an inverse correlation of bilirubin with ACS, which in shows fact that bilirubin acts as an antioxidant and has cardioprotective action and patients with ACS have lower levels of bilirubin. This can use as a factor for screening individuals who have high risk for ACS and preventive strategies applied in them before the onset of overt ACS.
ABSTRACT
Objective To study the antioxidant effect of serum bilirubin,an endogenous antioxidants,in the patients with lung cancer. Methods A total of 402 patients with lung cancer(patient group)and 422 healthy individuals(control group)were enrolled in this study. The concentrations of total bilirubin(TBIL)and direct bili-rubin(DBIL)were measured using Diazonium Salts reagent on an automated chemistry analyzer(AU5821,Beck-man Coulter)and concentrations of indirect bilirubin(IBIL)were calculated based on concentrations of TBIL and DBIL. The total activity of SOD and MDA concentrations of 104 patients and 57 controls were measured using Xan-thine oxidase and TBA reagents respectively. All data were analyzed using SPSS 19.0 Software. Results Compared with the control group,the concentrations of TBIL,DBIL,IBIL and the activity of SOD in the patient group were decreased(P < 0.05)but the concentrations of MDA were increased. However,no tendency was found from T1 to T4(TNM)groups. Conclusion There is antioxidant dysfunction within patient with lung cancer and the serum bilirubin would be involved in this process.
