Uric acid (UA) levels are associated with many diseases including those related to lifestyle. The aim of this study was to evaluate the influence of clinical and anthropometric parameters on UA and xanthine (X) levels during pregnancy and postpartum in women with physiological pregnancy and pregnancy complicated by gestational diabetes mellitus (GDM), and to evaluate their impact on adverse perinatal outcomes. A total of 143 participants were included. Analyte levels were determined by HPLC with ultraviolet detection (HPLC-UV). Several single-nucleotide polymorphisms (SNPs) in UA transporters were genotyped using commercial assays. UA levels were higher within GDM women with pre-gestational obesity, those in high-risk groups, and those who required insulin during pregnancy. X levels were higher in the GDM group during pregnancy and also postpartum. Positive correlations between UA and X levels with body mass index (BMI) and glycemia levels were found. Gestational age at delivery was negatively correlated with UA and X levels postpartum. Postpartum X levels were significantly higher in women who underwent caesarean sections. Our data support a possible link between increased UA levels and a high-risk GDM subtype. UA levels were higher among women whose glucose tolerance was severely disturbed. Mid-gestational UA and X levels were not linked to adverse perinatal outcomes.


Background: Microalbuminuria is a known risk factor for the development of clinical nephropathy in diabetes and also an independent risk factor for cardiovascular disease. Microalbuminuria is a marker of a pathophysiological process that causes both increased renal albumin loss and atherothrombosis. Microalbuminuria is hallmark for early detection of diabetic nephropathy. An elevated urinary albumin excretion is a marker of endothelial dysfunction that symbolizes the kidney’s way to translate the existence of vascular damage. The aim of this study was to evaluate the independent determinants of urinary albumin excretion, and association between biochemical parameters and socio-demographic factors in Diabetic patients. Materials and Methods: This is a hospital based cross sectional study included diagnosed case of Diabetic patients. Serum uric acid concentrations were measured by enzymatic method (uricase-peroxidase), HbA1c was measured using the principle of dry chemistry, Blood Sugar measured by Glucose oxidase peroxidase (GOD/POD) method and urinary albumin excretion was measured with an immunoturbidometric assay. Results: Based on categorization of Urinary albumin excretion, 65% normoalbuminuric, 27% microalbuminuric and 8% macroalbuminuric are found in our study population. The frequency of hyperuricemia was found to be 43%. The prevalence of albuminuria ncreased significantly with increasing glycaemia. Pearsons Correlation coefficient by bivariate analysis of Urinary albumin excretion with confounding variables shows significant positive correlation with onset of DM (r=0.203, P=0.013), Systolic Blood Pressure (r=0.355, P=0.001), Diastolic Blood Pressure (r=0.405, P=0.001), Uricacid (r=0.352, P=0.001), HbA1c (r=0.212, P=0.005) and Smoking (r=0.265, P=0.01). Multiple regression test shows that independent determinant of UAE are Blood Pressure {Diastolic (β=0.313, P=0.006) /Systolic (β=0.309, P=0.002)}, HbA1c (β=0.187, P=0.010), Uric acid (β=0.331, P=0.0001) and Onset of DM (β=0.199,P=0.041). Conclusion: Albuminuria is therefore an important risk factor to measure in patients at risk. The findings extend the relationship between confounding variables and the urinary albumin excretion which emphasize on the importance of screening for icroalbuminuria, Serum Uric Acid to prevent renal dysfunction, HbA1c measurement on a regular interval for good glycemic control and the other variables for regular physiological process of body. Further examination is needed in a large population size to clarify the validity between the biochemical parameters

Preeclampsia is a multisystem disorder characterized by gestational hypertension after the 20th week of gestation with proteinuria, is common and dangerous adverse event of pregnancy. Several studies reported relationship between uric acid concentrations and severity of disease in pregnant women. The objective of this study was to explore the relation between serum uric acid level and perinatal outcomes. A case–control study conducted in Sulaimani Maternity Teaching Hospital from January 2014 to July 2014. Included 100 pregnant women in third trimester with signs and symptoms of labour, who had no comorbid diseases. Grouped to 30 control without hypertension, 30 with pregnancy induced hypertension (PIH) and 40 with severe preeclampsia based on clinical and laboratory evaluation. SPSS v21 was used for obtain mean, standard deviation, frequency and percentage. One way ANOVA test used to obtain P value with consider <0.05 significant value. Results show serum uric acid mean and standard deviation (±SD) for control, PIH and severe preeclampsia groups were (5.83 ± 9.544), (4.35 ± 1.372) and (7.59 ± 0.508) respectively. The positive and significant (˂ 0.001) correlation coefficient was found between high serum uric acid level and oligohydramnios, low birth weight and low Apgar score. The highest level of serum uric acid was recorded in preeclampsia group and the lowest level was in PIH group. Significant and adverse perinatal outcomes relation were noted in the patients with high serum uric acid (>7 mg/dl); decreased amniotic fluid index (AFI), caused low birth weight and low Apgar score. In   conclusion that severity of illness in pregnant preeclampsia cases can be estimated by serum uric acid level and high serum uric acid indicate high risk cases. Maternal serum uric acid is a useful index for estimate fetal health status and predict neonate outcomes.

Background: Liver cirrhosis is one of the most common causes of morbidity and mortality. The availability of liver transplant has stressed on the need for accurate prognostication. Various scoring systems have been developed for the same and studies have been conducted to find the correlation of various biochemical parameters with these.Methods: This is a cross sectional study conducted on 100 patients with stigmata of liver cell failure on clinical examination and substantiated by imaging. Serum Uric acid and other biochemical parameters were determined. Child Turcotte Pugh Score, Model for End Stage Liver Disease (MELD) score, United Kingdom Model for End Stage Liver Disease (UKELD) score was calculated and the correlation obtained.Results: The study showed significant, positive correlation between uric acid level and CTP, MELD and UKELD score. The study also showed the positive correlation of serum uric acid with various biochemical parameters such as total bilirubin, Prothrombin time/ International Normalized Ratio (PT/INR) and serum creatinine and negative correlation with serum albumin, with a significant p value. The mean serum uric acid was found to be 4.79(4.79± 2.0)Conclusions: The study showed a correlation between serum uric acid and the various available scoring systems such as CTP score, MELD and UKELD score. Hence serum uric acid can be used as an alternative prognostic parameter in predicting the severity and prognosis of cirrhosis of liver.
