This study was designed to establish reference ranges for serum uric acid among healthy adult Assamese population. Samples from 1470 aged 35–86 years were used to establish age and sex related reference range by the centile method (central 95 percentile) for serum uric acid level. There were 51% (n=754) males and 49% (n=716) females; 75.9% (n=1115) of them were from urban area and the rest 24.1% (n=355) were from the rural area. Majority of the population were nonvegetarian (98.6%,n=1450) and only 1.4% (n=20) were vegetarian. The mean age, weight, height, and uric acid of the studied group were53.6±11.3years,62.6±10.5 kg,160±9.4 cm, and5.5±1.4 mg/dL, respectively. There is a statistically significant difference in the mean value of the abovementioned parameters between male and female. The observed reference range of uric acid in the population is 2.6–8.2 mg/dL which is wider than the current reference range used in the laboratory. Except gender (P<0.0001), we did not find any significant relation of uric acid with other selected factors.

Background: Serum uric acid has been closely linked and considered as an independent risk factor for development of hypertension. This study was carried out to assess the serum uric acid levels in essential hypertension and its correlation with the severity and known duration of hypertension.Methods: The present observational case control study was conducted between November 2019 to February 2020 on total 100 out patients (30-65 years) of which 50 known cases of essential hypertension irrespective of treatment status and were graded into different stages of hypertension as per Joint National Committee VII (JNC VII) guidelines. Rest 50 patients who were age- sex matched and without any co-morbidity were included as control. Relevant clinical and laboratory data were recorded using proforma. Statistical analysis was done using Statistical package for social software (SPSS) software.Results: Mean systolic/diastolic blood pressure (BP) was found significantly higher in cases 168/102 mmHg compare to control 114/74 mmHg. Among cases maximum patients were found in stage 2 hypertension which has significant difference in mean systolic/diastolic BP (186/112 mmHg, p<0.001) compare with stage 1 (146/94 mmHg) and isolated hypertensive patients (148/85 mmHg). Serum uric acid levels were significantly higher in stage 2 than other two hypertensive stages among cases and also compare to controls. Patients with >5 years of hypertension also has significant high serum uric acid level than <5 years of hypertension.Conclusions: Serum uric acid can be used probably as an early biochemical marker to determine the severity of hypertension as stage 2 hypertensive had more elevation in serum uric acid levels as compared to other hypertensive patients.

Background: Few studies have assessed the relation of uric acid level with the severity of coronary  artery disease (CAD). This study investigated the association between high uric acid levels with the  presence and severity of CAD.Materials and Methods: This study was designed as an observational cohort study. The study was  composed of 180 patients admitted at our institution due to symptoms related to CAD. Patients  having angiographic evidence of stenosis in coronary artery were as case group and without stenosis  control group. Patients with high uric acid (hyperuricemia) were defined as serum uric acid  concentration ?7.0mg/dl or ?420 ?mol/L in men and ?6mg/dl or ?360 ? mol/L in women. The  presence of CAD has been defined as the Gensini score being ?1.  Results: There was a statistically significant difference between the mean uric acid levels of patients  with and without CAD (358.23±71.11 ?mol/l vs251.32±54.92 ?mol/l respectively, p<0.001). There  was a statistically significant difference between ejection fraction of patients with and without CAD  (54.50±9.25 vs. 63.16±6.56 respectively, p?0.001). Spearman correlation analysis demonstrated a  positive correlation between the serum uric acid level and the severity of CAD (p=?0.001, r=0.39).  When patients were classified into four groups according to their Gensini score, mean serum uric  acid level was found to be significantly increased across the tertiles, and a statistically significant  difference was detected between the tertiles (p= ?0.001).  Conclusion: In conclusion, a significant association has been found between serum uric acid level  and the presence and severity of CAD. In addition to the evaluation of conventional risk factors in  daily clinical practice, the measurement of uric acid level might provide significant prognostic  benefits in terms of global cardiovascular risk and management of the patients.

Abstract Introduction: Elevated fibrinogen levels are well recognized as an independent risk factor for cardiovascular events in adults. Current research highlights the need to understand the mechanisms that influence fibrinogen levels in adolescents in order to elucidate its role in early onset ischaemic heart disease in young people. Depressed levels of fibrinogen are observed in a range of pathological conditions including acquired and congenital hypo- and afibrinogenaemias, consumptive coagulopathies, carcinoma and liver disease. Appropriate determination of the status of fibrinogen levels in patients is vital in identifying fibrinogen as a risk factor for cardiovascular events and in the investigation of coagulopathy. Ascertaining the meaningful status of the fibrinogen level in a patient relies on comparison with a reference range determined by the same methodology using an analogous population from which the patient originates. We present a reference range for Clauss fibrinogen determination in adolescents aged 12–14 years using the Sysmex CA-1500 coagulometer (Sysmex Corp., Kobe; Japan). Methodology: Blood samples for fibrinogen determination were collected from 240 adolescent schoolchildren aged between 12 and 14 years (M=119; F=121). All of the children were healthy with no apparent underlying pathology. Early morning samples were collected into siliconised glass BD Vacutainers containing tri-sodium citrate (Ref: 367691) and analysed within 4 hours of collection. Fibrinogen determination was performed using Dade-Behring thrombin and Owrens Veronal buffer reagents. Calibration of the Clauss fibrinogen assay was performed using NIBSC WHO International reference plasma for human fibrinogen (product number 98/612). Results: Fibrinogen results for males and females were examined for normality using Anderson-Darling and Kolmogorov-Smirnov tests. Results were found to be normally distributed and reference ranges constructed using the arithmetic mean +/− 1.96SDs. Male and female results were examined using the two-sample T- test for gender differences where p&lt;0.05 indicates a statistically significant difference. Fibrinogen data from the adolescent group (Table) were compared with 209 healthy adults (F=151; M=58: aged 21–55 years for both gender) tested in the same way. N Mean (g/l) SD Ref Range (g/l) Two sample test for gender difference (p) Adolescents Male 119 2.66 0.464 1.76 – 3.58 0.76 Female 121 2.67 0.467 1.76 – 3.59 Total sample 240 2.67 0.465 1.76 – 3.58 Adults Male 58 2.71 0.672 1.37 – 4.05 &lt;0.05 Female 151 2.99 0.653 1.68 – 4.29 Total sample 209 2.93 0.663 1.60 – 4.30 Conclusion: Reference ranges for Clauss fibrinogen for school children aged 12–14 years (1.8–3.6g/l) determined using the Sysmex CA-1500 coagulometer differ from the reference range for the healthy adult population (1.6–4.3g/l) determined using the same analyzer and methodology. No statistically significant difference was observed between adolescent male and female cohorts in contrast to significant gender differences observed within the healthy adult population. Reference ranges described in our study show the upper limit in adolescents to be lower than in the healthy adult population. The meaningful assessment of fibrinogen as a risk factor for cardiovascular events in young people should take cognizance of the age specific reference interval. The use of an appropriate, robust reference range for young people is essential in evaluating the influence of contributory risk factors for cardiovascular disease such as diet, body mass and exercise. Assessment of haemostatic function and investigations of coagulopathies in adolescents should be undertaken with reference to age specific ranges where available. This study was approved by the LREC and informed consent was obtained from parents/guardians.

The purpose of this study is to determine the activity of serum adenosine deaminase (ADA) in healthy people, in connection with significant differences in published reference ranges from different authors. In our study, we examined 160 healthy subjects aged 18 to 84, of whom 64 were men and 96 women. We have determined serum adenosine deaminase levels using a method based on the ability of the enzyme adenosine deaminase to catalyze the deamination of adenosine to inosine and ammonia. The catalytic concentration is determined spectrophotometrically by the rate of reduction of NADH measured at 340 nm. We found that normal serum ADA values among our healthy subjects are higher than the recommended reference range for the method we use, namely below 18 U/l. Using the percentile method, we worked out the following reference ranges: for women 14.53 - 25.73 U/l and for men 18.46 – 27.50 U/l. For women, the mean value is 21.07 U/l, and for men 21.30 U/l. At 95% CI, the serum ADA values of almost all subjects included in the study are within the recommended and other authors range of 11.50 - 25.00 U/l.

Hyperuricemia is associated with higher mortality in patients suffering from hypertension, coronary heart disease, cerebrovascular events, metabolic syndrome, insulin resistance, gout and renal stone formation and it is more in individuals with diabetes. The prevalence of hyperuricemia is high in T2DM. The aim of the present study was to assess the relationship between hyperuricemia and blood pressure in T2DM subjects and thus to help the clinician for early diagnosis, treatment and to prevent further complications. Total 350 study subjects were enrolled for this study; among them 203 were T2DM with normal level of serum uric acid level and 147 were T2DM with high serum uric acid level. It was observed that systolic blood pressure was significantly higher (134.5±9.6 mm of Hg) in T2DM with hyperuricemia (p<0.001) than T2DM with normal serum uric acid level (123.3±10.9 mm of Hg). On the other hand diastolic blood pressure was significantly higher (87.1±5.9 mm of Hg) in T2DM with hyperuricemia (p<0.001) than T2DM with normal serum uric acid level (79.6±8.3 mm of Hg). Age (years) showed no significant difference between T2DM with serum uric acid<7 mg/dl and T2DM with serum uric acid>7 mg/dl (p<0.05). In our study it was revealed that males were in greater risk of developing hyperuricemia. BMI was significantly (p<0.001) greater in T2DM subjects who had normal serum uric acid level (27.9±3.8) than with those who had serum uric acid>7 mg/dl (24.4±3.83). No significant differences were found in FBS, blood sugar 2 hours after breakfast, HbA1C, serum creatinine and blood urea between groups.Bangladesh J Med Biochem 2016; 9(2): 49-53

Background: Pre-eclampsia is a serious disorder of pregnancy with unknown ethological factors that may occur at any stage of second or third trimester of pregnancy. The objectives of the present study were to assess changes in complete blood counts including platelets, liver enzymes and serum uric acid in pre-eclamptic cases compared to second-half normal pregnant and non-pregnant Sudanese women and their correlations to other biomarkers.Methods: This was a cross-sectional, case-control study performed from December 2008 to December 2010; in Omdurman Maternity Hospital, in concomitance with other studies in pre-eclampsia. The sample size included three groups, 72 up pre-eclamptic cases in their recent pregnancies, 96 normal pregnant in their second half of pregnancy and 63 non- pregnant (control) women; a total of 231 subjects. Questionnaire Interviews and clinical examination were done for all participants. Laboratory investigations were done including complete blood picture, liver enzymes and uric acid.  Results: The mean Hb concentration of the pre-eclamptic (11.3g/dl±1.7) was statistically significantly lower than that of the non-pregnant (12.1g/dl±0.2) (P=0.01) but not from that of the normal pregnant (11.4g/dl±0.1) (P=0.882) .There was no statistical significant difference in the mean WBC count between the pre-eclamptic (7.4x103/mm3±0.3) and non-pregnant (7.3x103/mm3±0.3) (P=0.797) and between the pre-eclamptic and normal pregnant (7.7x103/mm3±0.2) (P=0.270). There was a considerable statistical significant decrease in the mean platelets count of the pre-eclamptic (236.4/mm3±8.3) compared to the non-pregnant group (322.0/mm3±10.4) (P=0.0001) s well as to the normal pregnant (275.0/mm3±8.9) (P = 0.003). In the pre-eclamptic cases, serum ALT correlated significantly with TWCC (r=0.26, P=0.03) and serum AST (r=0.65, P=0.000). In the pre-eclamptic cases, serum AST correlated significantly with Hb (r=0.26, P=0.03), serum ALT and serum uric acid (r=0.36, P=0.01).Conclusions: There was a considerable statistical significant decrease in mean platelets count of the pre-eclamptic compared to the non-pregnant group and to the normal pregnant may be explained by hemodilution; whereas further decrease was due to pre-eclampsia. ALT and AST are strong prognostic indicators of pre-eclampsia.

Background: Pre-eclampsia is a leading cause of fetomaternal and perinatal morbidity and mortality. The role of serum uric acid (SUA) in determining the complications of preeclampsia has been controversial. This study compared mean SUA levels between severe pre-eclamptics and normotensive women at term and ascertained its correlation with outcomes of preeclampsia; as well as determined if there is a threshold value of SUA level beyond which fetomaternal complications occur.Methods: A case-controlled study where 80 severe pre-eclamptics at term and 80 normotensive women matched for gestational age were recruited. Blood samples were collected from them for assay of SUA levels and they were followed till delivery. The fetomaternal outcomes and the corresponding SUA levels at diagnosis were documented and variables statistically analyzed. A receiver operating characteristic curve was used to determine the cut-off value of SUA beyond which adverse fetomateral complications are likely to occur in pre-eclampsia.Results: The mean SUA level in severe pre-eclamptics (0.283±0.09 mmol/l) was not significantly higher than that of normotensive women (0.263±0.09 mmol/l, p=0.13). There was a weak positive correlation between the SUA levels and fetomaternal outcomes [maternal (r=0.102, p=0.236) and fetal (r=0.096, p=0.226)]. The study was unable to identify the threshold SUA level at which adverse fetomaternal outcomes occur as the values of SUA were closely related.Conclusions: SUA levels of pre-eclamptics and normotensive women did not show significant difference and correlated weakly with fetomaternal outcomes and are therefore poor predictor of fetomaternal outcomes in pre-eclampsia.

AbstractSerum uric acid (SUA) level has been suggested to be associated with cardiovascular disease, diabetes and metabolic syndrome. However, little is known about the relationship between SUA and liver enzymes activity in the general population. The present study aimed to assess the relationship between SUA and serum liver enzymes in an adult population in Bangladesh. In this cross-sectional study, a total of 410 blood samples were collected from apparently healthy adults aged > 18 years. SUA, liver enzymes, lipid profile and other biochemical markers were measured in the collected samples by using standard methods. Multinomial logistic regression model was used to assess the relationship between SUA and elevated levels of liver enzymes among the participants. Overall, the prevalence of hyperuricemia was 30.1% with 32.2% in male and 18.6% in female participants. About 33% of the participants had at least one or more elevated levels of liver enzymes. The mean level of SUA was significantly higher in males (389.3 ± 96.9 µmol/L) than in the female (290.4 ± 89.8 µmol/L) subjects (p < 0.001). There was a significant difference in the mean levels of serum ALT and GGT between the male (34.5 ± 16.0 U/L and 26.7 ± 19.5 U/L, respectively) and female (25.0 ± 13.0 U/L and 19.5 ± 13.2 U/L, respectively) participants (p < 0.001 and p < 0.01, respectively). An increasing trend was observed in the mean levels of serum ALT and GGT across the SUA quartile groups (p < 0.001 and p < 0.01, respectively). SUA showed a positive and significant correlation with serum ALT (p < 0.001) and GGT (p < 0.01). In further statistical analysis after adjustment for potential confounders, SUA showed an independent and significant association with serum ALT and GGT in all regression models. In conclusion, SUA was strongly associated with serum levels of ALT and GGT after adjustment for potential confounders. More prospective studies are needed to clarify the complex relationship between SUA and liver enzymes in the general population.
