Introduction: Perinatal asphyxia is one of the leading causes of perinatal morbidity and mortality. Feasible and early biochemical markers to diagnose and predict the neurologic outcome is a great need of time as APGAR score alone is inuenced by various factors. The present study was performed to determine the urinary uric acid to creatinine ratio in perinatal asphyxia and its correlation with APGAR score and compare urinary uric acid to creatinine ratio with Sarnat and Sarnat staging. Materials and Methods: This study was carried out on 100 term neonates with an equal number of cases and control 50 each, control group being the neonates with Apgar score ≥ 7 at 1 minute of life and cases being the neonates who suffered from perinatal asphyxia with Apgar < 7 at 1 minute of life. The spot urine sample was collected within 24 hours of birth and their uric acid and creatinine levels were measured and the ratio calculated. Asphyxiated neonates were classied according to Sarnat and Sarnat staging. We Compare UA/Cr ratio with Apgar score and HIE staging using Sarnat and Sarnat staging.Results: On comparison of UUA/Cr among cases and controls we found that ratio was signicantly higher in asphyxiated neonates as compared to non asphyxiate neonates. (Control vs. Cases Group: 2.4 ± 1 vs. 3.6 ± 1.5; p –value < 0.0001). On comparison of UUA/Cr among cases with Sarnat and Sarnat staging of HIE, there is a signicant difference observed in mean UA/Cr ratio across Sarnat and Sarnat staging of HIE (F – Value = 68.760; p – value = 0.0001). Conclusion: Urinary uric acid and creatinine ratio can be used as markers for perinatal asphyxia for screening in centers where other markers for assessing perinatal asphyxia are not available. Urinary uric acid and creatinine ratio is a non-invasive, cheap and easily available marker for assessing the severity perinatal asphyxia.

Background: Perinatal asphyxia is a common neonatal problem and there is significant contribution to neonatal morbidity and mortality. It is regarded as an important and common cause of preventable cerebral injury. The prediction of perinatal asphyxial outcome is important but formidable. There is only a limited role for the Apgar score for predicting the immediate outcome, such as HIE and the long-term neurological sequelae observational error can happen in APGAR. But biochemical parameters can be truly relied upon. This study was to evaluate the utility of urinary uric acid to creatinine ratio (UA/CR ratio) as non-invasive, easy, cheap and at the same time early biochemical means of asphyxia diagnosis.Methods: In this prospective case control study conducted in KAPV Government medical college between Feb 2017 to Sept 2017, 100 asphyxiated and 100 non-asphyxiated newborns were included. Detailed history and assessment were for all the enrolled newborns. Spot urine samples were sent for uric acid and creatinine estimation. Results were recorded, and statistical analysis was done.Results: The mean Uric acid/Creatinine ratio in the cases and controls groups were 2.58±1.09 and 0.86±0.17 respectively. The ratio also correlated well with the stage of HIE.Conclusions: The ratio of UA/Cr enables early and rapid recognition of asphyxial injury and also the assessment of its severity and the potential for short term morbidity or death.

Objective: The value of urinary uric acid and creatinine ratio in neonatal asphyxia. Method: This was a prospective observational study conducted over one year, on 45 newborns admitted in NICU with perinatal asphyxia. Cord blood from the umbilical artery was sent for pH analysis and urinary uric acid and creatinine levels were estimated in spot urine samples. Results: The urinary uric acid and creatinine ratio had a positive correlation with low APGAR scores at the 1st and 5th minute. Also, urinary uric acid to creatinine ratios was significantly higher in infants with severe HIE (3.18±0.61) when compared with infants of moderate HIE (2.19±0.32). It showed a significant negative correlation with pH of cord blood in neonates with perinatal asphyxia. Conclusion: The urinary uric acid and creatinine ratio can be used as a supportive diagnostic test for early diagnosis of perinatal asphyxia.

Fructose consumption has been recently related to an epidemic of metabolic syndrome, and hyperuricemia plays a pathogenic role in fructose-induced metabolic syndrome. Fructose-fed rats showed hyperuricemia and renal dysfunction with reductions of the urinary uric acid/creatinine ratio and fractional excretion of uric acid (FEur), as well as other features of metabolic syndrome. Lowering serum uric acid levels with allopurinol, rutin, and quercetin increased the urinary uric acid/creatinine ratio and FEurand attenuated other fructose-induced metabolic abnormalities in rats, demonstrating that hyperuricemia contributed to the deficiency of renal uric acid excretion in this model. Furthermore, we found that fructose upregulated the expression levels of rSLC2A9v2 and renal-specific transporter (rRST), downregulated the expression levels of organic anion transporters (rOAT1 and rUAT) and organic cation transporters (rOCT1 and rOCT2), with the regulators prostaglandin E2(PGE2) elevation and nitric oxide (NO) reduction in rat kidney. Allopurinol, rutin, and quercetin reversed dysregulations of these transporters with PGE2reduction and NO elevation in the kidney of fructose-fed rats. These results suggested that dysregulations of renal rSLC2A9v2, rRST, rOAT1, rUAT, rOCT1, and rOCT2 contributed to fructose-induced hyperuricemia and renal dysfunction. Therefore, these renal transporters may represent novel therapeutic targets for the treatment of hyperuricemia and renal dysfunction in fructose-induced metabolic syndrome.

Background: Perinatal asphyxia is amongst the common problem of neonates and there exists a significant contribution to the neonatal morbidity and mortality. It is observed as a common and a vital cause of the preventable cerebral injury. The prediction of the perinatal asphyxial outcome is very important but dreadful. There is a limited role for APGAR score to predict the immediate outcome, like HIE and the long-term neurological sequelae observational error may happen in APGAR. But the biochemical parameters can truly be relied upon. This study was done to assess urinary uric acid/urinary creatinine ratio (UA/Cr) as a non-invasive marker for perinatal asphyxia and co-relate its absolute value to the degree of the perinatal asphyxia.Methods: In this prospective case control study conducted in the Pediatrics Department of Shri Ram Murti Smarak Institute of Medical Sciences between Nov 2017 to May 2019, 42 asphyxiated and 42 non-asphyxiated newborns were included. Detailed history and assessment were for all the enrolled newborns. Spot urine samples were sent for the uric acid and creatinine estimation. Results were documented, and statistical analysis was performed.Results: Urinary uric acid to creatinine ratio used as additional non-invasive, early and easy biochemical marker of the birth asphyxia that biochemically supports severity grading and clinical diagnosis of the asphyxia by APGAR score.Conclusions: The ratio of the urinary uric acid and creatinine enables rapid and early recognition of asphyxial injury and also the evaluation of its severity and potential for short-term morbidity or death.

Abstract Background and Aims Hypercalciuria can clinically present itself as gross hematuria, microscopic hematuria, dysuria or abdominal pain without urinary lithiasis. It is also one of main metabolic causes of urinary lithiasis in children. In Nelson pediatrics, hypercalciuria is defined by a 24 -hour urine for calcium excretion&gt;4mg/kg/day. A spot urine calcium creatinine ratio of &gt;0.2, is considered abnormal in older children and adolescents. Both of them are not a standardized detect in children. Fasting and postprandial spot urinary calcium creatinine ratios may not detect hypercalciuria so accurately, that a 24-hour urine is preferred. In addition, 24hr urine collection is frequently under- or over-collected, which leads to an inadequate sampling hard to pick up which one the more accurate calculating methodology for the hypercalciuria detection with 24hr urine is. In this study, we evaluated the comparisons of 24 hr urine calcium creatinine ratio(Ca/Cr), 24hr urine calcium excretion(mg/kg)(Ca/Kg) and CCCR in school aged children. 24-hour urine for calcium excretion&gt;4mg/kg/day 24-hour urine calcium creatinine ratio of &gt;0.2 Calcium creatinine clearance ratio(CCCR); (24-hour U-calcium/P-total calcium) / (24-hour U-creatinine/P-creatinine), as known as fractional excretion of calcium(FeCa) Method We enrolled 250 normal kidney function patients who’s age is 7 to 18 year, was able to collect 24 hr urine in a single hospital unit. We conducted 24 hr urine collection, serum calcium creatinine levels on the same day from January 2007 to December 2019. We analyze of each values. We used SPSS. 25.0 Results

Background: Perinatal asphyxia is a common neonatal problem and contributes significantly to neonatal morbidity and mortality. Every hour, 104 children die as a result of asphyxia. In India; between 250,000 to 350,000 infants die each year secondary to birth asphyxia and mostly within the first three days of life. The present study was performed to determine the Urinary Uric Acid to Creatinine Ratio in perinatal asphyxia and its correlation between APGAR score and urinary uric acid to creatinine ratio in perinatal asphyxia.Methods: A randomized case control hospital-based study was conducted on 50 asphyxiated and 50 normal newborn. Urinary uric acid and creatinine were estimated in spot urine within 24 hours after birth in both cases and controls. A ratio between the concentrations of uric acid to creatinine was estimated and comparison done between cases and controls.Results: Urinary uric acid to creatinine ratio can be used as an additional non-invasive, easy and early biochemical marker of birth asphyxia which biochemically supports the clinical diagnosis and the severity grading of asphyxia by APGAR score.Conclusions: Urinary uric acid to creatinine ratio can be used as an additional non-invasive, easy and early biochemical marker of birth asphyxia which biochemically supports the clinical diagnosis and the severity grading of asphyxia by APGAR score.

Background: Uric acid levels in urine are measured using urine specimens 24 hours or by uric acid glomerular filtration rate (UAGFR) with spot urine, which additionally requires a blood sample. This study aimed to investigate whether urinary uric acid creatinine ratio (UUACr) obtained by spot urine alone could be recognized as a substitute for UAGFR value, and hyperuricosuria can be screened by UUACr. UUACr is known to vary with age and regional differences. This study focused on the reference value of each value in Korean young populations.Method: We enrolled Korean subjects 1–20 years with normal kidney function, from a single hospital, classified into 5 age groups, 1–5 years, 6–8 years, 9–12 years, 13–15 years, and 16–20 years. We checked spot urine uric acid, creatinine and serum uric acid, creatinine levels on the same day from February 2014 to December 2018. We measured the average of UAGFR and UUACr in each groups. The UUACr cut-off value of the upper 2 standard deviation (SD) of UAGFR were taken.Results: The upper 2 SD of UUACr (mg/mg) and UAGFR (mg/dL) were determined in all age groups. UUACr decreased with grown up (P=0.000), but UAGFR were not statistically different among the groups. UUACr and UAGFR were not significantly different by gender. UUACr and UAGFR were positively correlated; UUACr cut-off value of upper 2 SD UAGFR (0.54 mg/dL) was 0.65 mg/mg in total age.Conclusions: UUACr could potentially be used to screen for hyperuricosuria.
