Role of Nuclear Factor-Kappa B Activation and Inflammatory Biomarkers in Critically Ill Children.

Mortality prediction is important for cautious monitoring and optimal management of critically ill children. The serum cytokine levels are elevated early in critical illness before the physiological parameters are deranged. This cross-sectional descriptive study included the critically ill children admitted in intensive care unit. Serial serum levels of IL-6, NF-κB and PELOD 2 scoring were measured and compared in 45 children (40 survivors, 5 non-survivors). The median IL-6 levels at 24 h and 72 h were significantly high in non-survivors when compared to survivors [median (IQR) = 1122 (1305) pg/ml vs. 564.39 (153) pg/ml and 1263 (626) pg/ml vs. 82 (191) pg/ml respectively; p <0.0001)]. There was an increasing trend of IL-6 in non-survivors when compared to the survivors. The NF-κB values were comparable. The IL-6 levels correlated well with the illness severity. IL-6 had superior prognostic value compared with NF-κB in predicting mortality.

UGT2B7 gene polymorphism and linkage disequilibrium in pediatric epileptic patients and their influence on sodium valproate monotherapy: A cohort study.

Background: Uridine 5'-diphospho glucuronosyl transferase (UGT) is the main enzyme responsible for the glucuronide conjugation, the principal metabolic pathway of sodium valproate. The objective of the study was to explore if there was an association between the UGT2B7 genetic polymorphism and clinical efficacy and safety in paediatric epileptic patients on sodium valproate monotherapy. Methods and materials: The cohort study included 100 pediatric epileptic patients aged 2-18 years who had been on sodium valproate monotherapy for at least 1 month. PCR-RFLP was carried out to assess the genetic polymorphism patterns of UGT2B7 (C161T, A268G, G211T). Based on the extent of seizure control throughout the 1-year follow-up, clinical outcome was assessed in terms of responders and non-responders. Hepatic, renal, and other lab parameters were assayed to determine safety. The SNPstat web software was used to calculate linkage disequilibrium. Results: Out of 100 patients, CC (38%), CT (43%), TT (19%) pattern was observed in UGT2B7 (C161T) gene, AA (15%), AG (39%), GG (46%) in (A268G) gene and GG (80%), GT (18%), TT (02%) in (G211T) gene. There was no statistical difference in clinical outcome with distinct UGT2B7 genetic polymorphism patterns, according to the findings. With low D' and R2 values, linkage disequilibrium between alleles was statistically insignificant. However, the associations of C161T and G211T with treatment response were significant (p = 0.014) in determining treatment response. Conclusion: Our findings show that the genetic variation of UGT2B7 had no bearing on the clinical outcome of epilepsy. Gene interactions, on the other hand, had an impact on treatment response.

UGT1A6 and UGT2B7 Gene Polymorphism and its Effect in Pediatric Epileptic Patients on Sodium Valproate Monotherapy.

OBJECTIVES: To evaluate the pattern of UGT1A6 and UGT2B7 gene polymorphism in pediatric epileptic patients and to compare the sodium valproate concentration in different patterns of UGT gene polymorphism. METHODS: In this cross-sectional study, 99 pediatric epileptic patients aged 2-18 y receiving Sodium valproate monotherapy for the past one month were included from JusticeK S Hegde Charitable hospital, Mangalore after obtaining informed consent. Genetic polymorphism patterns were evaluated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Trough level serum valproate concentration was estimated by high-performance liquid chromatography (HPLC). Sodium valproate concentration in different UGT genotypes was compared by Analysis of Variance (ANOVA). P value <0.05 was considered significant. RESULTS: In the present study population, the predominant mutant allele pattern was observed in UGT1A6 (T19G, A541G, A552C) gene. In UGT2B7 (A268G, C161T) showed predominant mutant allele pattern while (G211T) showed predominant wild type. Mean steady-state sodium valproate concentration was 105.40 ± 49.9 µg/ml and adjusted sodium valproate concentration was 5.5 ± 3.2 mg/kg/L. It was found that there was no statistical difference in sodium valproate concentration in different UGT1A6 and UGT2B7 gene polymorphism. CONCLUSION: The present study concluded that though there was a difference in pattern of gene polymorphism with concerning UGT1A6 and UGT2B7, however, it has not contributed to variation in serum concentration of sodium valproate in the present study population.

Effects of Long-term Antiepileptic Therapy on Carotid Artery Intima- Media Thickness.

BACKGROUND: Common first-line antiepileptic drugs (AEDs) used in children are valproate, phenytoin, and levetiracetam. Many side effects for these AEDs are reported including obesity, atherosclerosis, and metabolic syndrome. The aim of our study was to evaluate changes in carotid artery intima-media thickness (CIMT) in epileptic children and to correlate with lipid profile of those who are on long-term antiepileptic therapy. MATERIALS AND METHODS: This case-control study was done over 18 months in department of pediatrics. Sample size was 84 with equal number of cases and controls. Epileptic children between 1 and 18 years of age receiving monotherapy with valproate, phenytoin, or levetiracetam for at least 6 months were included in the study. Measurement of CIMT was done by B mode ultrasonography. Lipid profile was analyzed. Statistical analysis was performed using one-way analysis of variance (ANOVA) test and Pearson correlation. RESULTS: Among 42 cases of epilepsy, 30 were on valproate, 9 on phenytoin, and 3 on levetiracetam monotherapy. No significant difference was noted in body mass index (BMI) among children receiving AED compared with that of controls (P = 0.82). Mean value for CIMT was significantly higher among valproate (0.43 ± 0.04, P ≤ 0.001), phenytoin (0.44 ± 0.04, P ≤ 0.001), and levetiracetam group (0.43 ± 0.03, P = 0.01) compared to controls (0.39 ± 0.01). Significant correlation was noted between CIMT and total cholesterol (P = 0.034), triglyceride (P = 0.011), low-density lipoprotein (P = 0.008), and very low-density lipoprotein (P = 0.011). CONCLUSION: Children on long-term monotherapy with valproate, phenytoin, and levetiracetam have significantly abnormal CIMT. This might be associated with atherosclerotic changes, and these children may require close follow-up to prevent cardiovascular and cerebrovascular risks.

Effect of gestational diabetes on the vitamin D levels in the neonates: a case control study.

BACKGROUND AND OBJECTIVES: The present study was conducted to determine the effect of maternal gestational diabetes on the Vitamin D levels of the mother and their newborns and to compare it with healthy mother-infant pairs. METHODS: The study design was a Case Control study. It was conducted at the antenatal unit of Obstetrics and Neonatal unit of Pediatrics department of a tertiary care hospital in costal Karnataka. Consecutive sample of otherwise healthy pregnant women presenting with Gestational Diabetes Mellitus (GDM) and their healthy term neonates were taken as study group. The weight matched healthy mothers and their healthy term neonates were taken as controls. The blood samples of the mothers, at term and the cord blood samples of the neonates were collected for estimating the Vitamin D levels. Vitamin D levels in the cases and controls were the primary outcome measures. RESULTS: The mean value of Vitamin D levels in the GDM mothers was 10.74 ng/ml and in the mothers forming the control group was 23.53ng/ml (p value < 0.001). The mean value of Vitamin D levels in GDM babies was 8.47ng/ml and was 19.51ng/ml in the control (p value < 0.001). CONCLUSION: Comparison of Vitamin D levels of mothers and infants of both groups showed a positive correlation. GDM seems to exacerbate the Vitamin D deficiency in the mothers and their neonates.

Pregnancy Outcome in Occupational Tobacco Exposure: A Cohort Study from South India.

BACKGROUND: Women constitute a significant labor pool in the Indian tobacco industry as bidi (hand-rolled cigarette) rollers. On an average, they roll around 600 bidis/day and are exposed to 120 g of tobacco and 3 g of nicotine. Bidis do not have chemical preservatives or stabilizing agents, and therefore, the rollers are exposed only to nicotine by handling and inhalation. The study objective was to assess pregnancy outcome in these women with occupational tobacco exposure. MATERIALS AND METHODS: A prospective cohort study of bidi-rollers (n = 177) and women with no tobacco exposure (n = 354), followed up for pregnancy outcome, neonatal anthropometry, and nicotine absorption by cotinine assays. Adjusted risk and adjusted mean differences with a 95% confidence interval were derived. RESULTS: Outcomes included increased adjusted risk for gestational hypertension (3.54 [1.21, 10.31]; P = 0.021) and fetal growth restriction (2.71 [1.39, 5.29]; P = 0.004). Risk for prematurity was not statistically significant (1.81 [0.74, 4.45]; P = 0.194). Lower adjusted mean difference of birth weight (-104 g [-177, -31]; P = 0.005), length (-0.4 cm [-0.8, -0.1]; P = 0.006), and head circumference (-0.4 cm [-0.6, -0.1]; P = 0.002) were seen with increased risk for small for gestational age (1.75 [1.12, 2.73]; P = 0.015). Nicotine absorption was evident in one-third of maternal and cord blood estimations. CONCLUSION: Occupational passive tobacco exposure results in adverse pregnancy outcome.

The presentation of long-chain fatty acid oxidation disorders (FAOD), unlike short and medium-chain disorders can be with secondary defects in mitochondrial function along with typical features of FAOD. We report an infant with Reye-like presentation and acylcarnitine profile suggestive of very-long-chain acyl-CoA dehydrogenase deficiency who had lactic acidosis and urine gas chromatographic pattern of mitochondrial defects.

Prevalence of Community-Acquired Methicillin-Resistant Staphylococcus aureus Nasal Colonization Among Children.

BACKGROUND: Invasive infections from community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) are increasingly being encountered in healthy children. Nasal colonization of MRSA is associated with increased risk for acquiring invasive disease. The objective of this study was to determine prevalence and risk factors for CA-MRSA nasal colonization among a healthy paediatric population and to determine antibiotic susceptibilities of S. aureus isolates. MATERIALS AND METHODS: Using a cross-sectional study design, children aged 1mnth-17y attending well-child clinic at an academic hospital and a local public school in Mangalore, India were screened for S. aureus colonization via nasal swabs. A questionnaire was administered and data on risk factors for nasal colonization was collected. Samples were obtained from the anterior nares and cultured quantitatively. S. aureus isolates were confirmed by growth on selective media and coagulase testing. Disk diffusion antibiotic susceptibility tests were performed according to Clinical and Laboratory Standard Institute guidelines. RESULTS: Of the 500 children included in the study, S. aureus was isolated from the anterior nares in 126 (25%) children; four (3%) isolates were classified as CA-MRSA. Factors associated with S. aureus nasal colonization were children <6 y old (p=0.030) and members of joint families (p=0.044). Resistance to many classes of antibiotics were noted among S. aureus isolates including trimethoprim-sulfamethoxazole (39%), ciprofloxacin (16%), erythromycin (19%) and clindamycin (5%). Inducible clindamycin resistance (positive D test) was detected in 11 of the erythromycin-resistant strains not already classified as resistant to clindamycin. No resistance to vancomycin was observed. CONCLUSION: Children in India have a high rate of nasal colonization of S. aureus. Nasal colonization of community-associated methicillin-resistant S. aureus exists but is still low among healthy children. The high rate of resistance to many classes of antibiotics among S. aureus strains is of great concern warranting continued surveillance and antimicrobial stewardship.

Otitis media with effusion in relation to socio economic status: a community based study.

Otitis media with effusion (OME) is the presence of non purulent effusion within the middle ear cleft. The symptoms of this disease are not alarming as in suppurative otitis media. The disease is common in young children. The main symptom of this disease is decreased hearing, which may sometime go unnoticed more so if the parents are not attentive. We conducted a community based study among 1,020 school children of the age group 5-10 years from schools of sub-urban areas of Dakshina Kannada district, Karnataka, to explore the relationship of OME in relation to socioeconomic status. Diagnosis of OME was done by clinical examination and tympanometry. Prevalence of OME was 4.5%. Out of 46 cases, 4% belong to upper class, 26% to upper middle class, 26% to lower middle class, 43% to upper lower class.

Mycoplasma pneumoniae infection in children with acute respiratory infection.

A prospective study was performed on 93 children admitted to Kasturba Medical College Hospital, Manipal and TMA Pai Rotary Hospital of Udupi and Karkala. Blood samples from 93 children admitted to the ward with no respiratory illness were taken as age-matched controls for the inpatients, IgM antibody against Mycoplasma pneumoniae was detected using a commercial kit (Virion-Serion ELISA, Germany) following the manufacturer's instructions. 23.96% of the inpatients with respiratory tract symptoms had IgM antibodies against Mycoplasma pneumoniae. The highest infection rate was found to be in the 2-5 and 5-10 year age group. The most common mode of presentation was an upper respiratory focus of infection with cervical lymphadenopathy. Bronchial breathing signifying pneumonic consolidation was significantly less in the Mycoplasma positive group (p = 0.006). There was no statistically significant difference in the radiological findings in the Mycoplasma positive and Mycoplasma negative groups.

Surgical implications of snakebites.

OBJECTIVE: Snakebites are a common problem in the pediatric age group. Local complications such as necrosis and compartment syndrome threaten limb survival even after control of systemic manifestations. Few recommendations exist about the nature and timing of surgical treatment. METHODS: A retrospective review of all children with snakebites presenting to the hospital was undertaken over a 6-year period. Records were reviewed with special emphasis on the type of surgical lesions seen and the treatment offered and their results. RESULTS: 44 of the 58 children required some form of local therapy. In the majority conservative treatment was successful. 28% of the patients needed debridement for local necrosis, and only 5 needed a skin graft, with good functional results over a period of 1 to 45 days. One child underwent an above knee amputation. Patients who required surgical intervention received significantly more vials of antivenin. CONCLUSION: Local complications of snakebite are frequent, but can be managed conservatively. Delayed excision of the resultant local necrosis is associated with good outcomes. The need for fasciotomy is rare.
