Prediction of severity of dengue infection in children based on hepatic involvement

Background and Aim

To assess the spectrum of hepatic involvement in children with dengue fever (DF) and prediction of severity of dengue infection by early detection of elevated liver enzymes.

Methods

This prospective observational study was conducted at a tertiary care hospital from June 2019 to September 2019. Children admitted with DF were included. Severity of DF was graded as dengue without warning sign (DNWS), with warning sign (DWS), and severe dengue fever (SDF) according to WHO criteria. Liver injury (LI) was defined as alanine aminotransferase (ALT) more than upper limit of normal irrespective of sex.

Results

Of 190 children (male, 109) with DF, 60 had DNWS, 49 had DWS, and 81 had SDF. A total of 100 children (52.6%) had LI. The distribution of hepatic involvement spectrum involves hepatomegaly (26.3%), hepatic tenderness (25.2%), features of acute liver failure (1.5%), raised level of ALT (52.6%), raised level of aspartateaminotransferase (AST) (65.8%), prolonged prothrombin time (7.3%), and reduced level of serum albumin (44.7%) in children. Of them, 5.8% and 6.8% of children had >tenfold increase in ALT and AST values. The degree of liver function derangement significantly (P < 0.05) increased with DF severity. In our study, ALT at 422 IU/L (10 times upper limit of normal [ULN]) and AST 689 IU/L (17 times ULN) had similar sensitivity and specificity as WHO recommended cutoff of 1000 IU/L (25 times of ULN) to detect SDF.

Conclusion

ALT ≥10 times and AST ≥17 times of ULN are as sensitive as ≥25 times (as recommended by WHO) to detect SDF.

Ratio of aspartate aminotransferase to alanine aminotransferase and alkaline phosphatase to total bilirubin in Wilsonian acute liver failure in children

BACKGROUND

Acute liver failure (ALF) caused by Wilson disease (WD) is always fatal. Therefore, a quick diagnosis of WD is needed to start immediate management. This study aims to determine the ratio of aspartate aminotransferase to alanine aminotransferase (AST/ALT) and the ratio of alkaline phosphatase to total bilirubin (ALP/TB) in diagnosing Wilsonian acute liver failure (WALF) in children.

METHODS

Sixty children with acute liver failure were included in this study, of whom 40 had WALF and 20 had a non-Wilsonian acute liver failure (non-WALF). The serum ALT, AST, alkaline phosphatase, and total bilirubin of each blood sample were measured. We evaluated the sensitivity and specificity of AST/ALT ratio and ALP/TB ratio in WALF diagnosis.

RESULTS

Consanguinity and Kayser-Fleischer (K-F) rings were found in 32.5% and 72.5% of WALF cases, respectively. The mean hemoglobin, median ALT, median alkaline phosphatase, and mean ceruloplasmin of children with WALF were lower than those in the non-WALF group. In WALF cases, the median AST/ALT ratio was higher than in non-WALF cases. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy of the ratio of AST to ALT were 70%, 95%, 96.5%, 61.3% and 78.3%, respectively. However, when the cutoff value is ≥ 1.85, the maximum sensitivity produced by the AST/ALT ratio is 77.5% and the specificity is 95%. The sensitivity, specificity, PPV, NPV, and diagnostic accuracy of the ratio of ALP/TB < 4 were 32.5%, 100%, 100%, 42.5%, and 55%, respectively. The overall mortality rate was 50%, while the WALF mortality was 60%.

CONCLUSION

A positive AST/ALT and ALP/TB ratio strongly suggest WALF, but a negative result does not exclude WALF. We cannot use these ratios as a diagnostic tool for children with WALF. In WALF cases, the mortality rate is remarkably high, and the high score of the new Wilson index predicts the mortality rate without liver transplantation.

Functional constipation in Bangladeshi school aged children: A hidden misty at community

BACKGROUND

Constipation is a common problem in children and a frequent cause of hospital visit in both primary & specialized care, which needs proper evaluation & management. Presentation of constipation is variable among children. In Bangladesh there has been no published data regarding constipation in community among school aged children.

AIM

To determine the magnitude of functional constipation and its risk factors in community among Bangladeshi school children.

METHODS

This descriptive cross sectional study was conducted in different schools of Dhaka division, Bangladesh. All school aged children between 5-16 years of age who attended school were included in this study. Samples were collected randomly. Proper clinical history & physical examinations (without digital rectal examination) & available investigations (if done previously) were recorded. Diagnosis of functional constipation was done by Rome IV criteria and was compared with children without constipation. Children with any red flag sign, known chronic disease or any findings suggestive of organic disease and on treatment of constipation were excluded. Statistical analysis of the results was done by using Windows based software device with Statistical Packages for Social Science 20. For all statistical tests, P value of less than 0.05 was considered as statistically significant.

RESULTS

Total study populations were 707 and male was 443 and female 264. Among them, 134 (19%) children had constipation. In constipated children, 78 children fulfilled the Rome IV criteria for functional constipation and it was 11% of total population. Mean age of children having functional constipation was 11.24 ± 3.54 years and Male female ratio was 1:1.78. Anorexia, nausea, abdominal pain, hard stool, blood with hard stool, alternate hard and loose stool and fecal mass in left iliac fossa were analyzed between two group and all were significantly higher in children with functional constipation group. Children of school, where toilet numbers were inadequate had 2.5 times more constipation risk in comparison to children of school with adequate toilet number (OR = 2.493, 95%CI: 1.214-5.120). Children who feel embarrassed to use toilet at school, had 3.6 times higher risk of constipation (OR = 3.552, 95%CI: 1.435-8.794). Here children with H/O affected sibs and parents/grandparents had 4 and 2.6 times more chance of constipation respectively in comparison to children without H/O affected sibs (OR = 3.977, 95%CI: 1.884–8.397) and parents/grandparents (OR = 2.569, 95%CI: 1.172-5.629). Children with inadequate fluid intake had 2 times more risk of constipation in comparison to children with adequate fluid intake (OR = 1.972, 95%CI: 1.135-3.426). Children who passed electronic screen time of > 2 h/d had 2 times more chance of constipation in comparison to children who passed electronic screen time < 2 h (OR = 2.138, 95%CI: 1.063-4.301).

CONCLUSION

Constipation is not uncommon in Bangladeshi school aged children. Inadequate toilet number, family history of constipation, inadequate fluid intake, feeling embarrassed to use toilet at school, and electronic screen time for > 2 h/d were found as risk factors in the present study for functional constipation.

Overweight, hypertension and microalbuminuria in urban and rural Bangladeshi schoolchildren

Background The prevalence of childhood overweight and obesity has increased over the last two decades due to high caloric intake and decreased physical activity. The dramatic increase in the prevalence of overweight children occurred in conjunction with increasing prevalence of hypertension. Microalbuminuria is an early sign of damage to the kidney and cardiovascular system. Hypertensive, overweight children have an increased chance of microalbuminuria. Objectives To assess the prevalence of overweight, hypertension, and microalbuminuria in urban and rural school going children and contributing risk factors and associations. Methods This cross-sectional study was done in schoolchildren aged 6 to 16 years, from urban and rural areas, in Bangladesh, from September 2015 untill August 2016. Subjects’ weights, heights, and blood pressures (BP) were measured. Overweight and hypertension (HTN) statuses were determined with age-appropriate standardized charts. Subjects were divided into overweight and normoweight groups to evaluate risk factors for overweight such as family history (F/H) of obesity, F/H of HTN, daily physical outdoor activities, and monthly family income by comparative analysis. All overweight children were divided into hypertensive and normotensive groups in order to compare their fasting lipid profiles, urine microalbumin, serum creatinine, and random blood sugar. Results A total of 976 schoolchildren from urban (471, 48.3%) and rural (505, 51.7%) areas were included. Overweight was observed in 22.3% of the urban group and in 8.1% of the rural group (P<0.001). Hypertension was observed in 24.7% of overweight children and in 2.5% of normal weight children (P<0.001).  Contributing risk factors for overweight were less physical outdoor activities, F/H of obesity, F/H of HTN, and higher family income (P<0.001). Microalbuminuria and random blood sugar were significantly increased in the overweight with hypertension group compared to the normotensive group (P <0.005). Conclusion Overweight is a health problem, noted especially in urban areas. Hypertension is also significantly increased in overweight children. Factors like F/H of hypertension, obesity, sedentary lifestyle, and higher socioeconomic status are significantly associated with overweight. Microalbuminuria and increased random blood sugar are also significantly higher observed in hypertensive overweight children compared to normotensive overweight children.

Alagille syndrome with moyamoya disease

<p>We report a 5 year old male child who presented with a history of progressive jaundice since infancy and generalized pruritus. He was also found to have typical triangular facies, posterior embryotoxon on both eyes, peripheral pulmonary stenosis and paucity of bile ducts in liver biopsy. Magnetic resonance angiography of brain showed typical features of moyamoya disease. The child was diagnosed as a case of Alagille syndrome. This particular syndrome with feature of moyamoya disease has been rarely reported.</p>
