Incidence, Risk Factors, and Outcomes of Acute Kidney Injury in Preterm Neonates Hospitalized in the Neonatology Unit, North India: A Single-center Experience.

Acute kidney injury (AKI) is common in premature newborns and is associated with high mortality. It is unclear which risk factors lead to AKI in these neonates. We aimed to determine the incidence, risk factors, and outcomes of AKI in preterm neonates in the neonatal intensive care unit (NICU). They were screened and staged for AKI as per the amended neonatal criteria of Kidney Disease Improving Global Outcomes and followed up until discharge or death. Serum creatinine levels and urine output were measured. The incidence of AKI was 18.5% (37/200 neonates). The majority developed non-oliguric AKI. The risk factors significantly associated with AKI in neonates were the presence of sepsis, birth asphyxia, shock, respiratory distress syndrome, and hypothermia. The majority of neonates with AKI had a birthweight <1500 g and a gestational age of <32 weeks and had a higher risk of mortality, in contrast to than those without AKI. Mortality and NICU stay were significantly higher among those with Stage 3 AKI compared with Stage 2 and Stage 1 AKI. To prevent AKI and reduce the burden of high mortality in premature neonates, it is essential to prevent sepsis, birth asphyxia, and respiratory distress syndrome, as well as to detect shock and patent ductus arteriosus as early as possible. There is a need for good antenatal care to reduce the burden of prematurity.

Neonatal mortality risk assessment using SNAPPE- II score in a neonatal intensive care unit.

BACKGROUND: There are many scoring systems to predict neonatal mortality and morbidity in neonatal intensive care units (NICU). One of the scoring systems is SNAPPE-II (Score for Neonatal Acute Physiology with Perinatal extension-II). This study was carried out to assess the validity of SNAPPE-II score (Score for Neonatal Acute Physiology with Perinatal Extension-II) as a predictor of neonatal mortality and duration of stay in a neonatal intensive care unit (NICU). METHODS: This prospective, observational study was carried out over a period of 12 months from June 2015 to May 2016. Two hundred fifty five neonates, who met the inclusion criteria admitted to NICU in tertiary care hospital, BPKIHS Hospital, Nepal were enrolled in the study and SNAPPE-II score was calculated. Receiver Operating Characteristic (ROC) curve was constructed to derive the best SNAPPE-II cut-off score for mortality. RESULTS: A total of 305 neonates were admitted to NICU over a period of one year. Among them, 255 neonates fulfilled the inclusion criteria. Out of 255 neonates, 45 neonates (17.6%) died and 210 were discharged. SNAPPE-II score was significantly higher among neonates who died compared to those who survived [median (IQR) 57 (42-64) vs. 22 (14-32), P < 0.001]. SNAPPE II score had discrimination to predict mortality with area under ROC Curve (AUC): 0.917 (95% CI, 0.854-0.980). The best cut - off score for predicting mortality was 38 with sensitivity 84.4%, specificity 91%, positive predictive value 66.7% and negative predictive value 96.5%. SNAPPE II score could not predict the duration of NICU stay (P = 0.477). CONCLUSION: SNAPPE- II is a useful tool to predict neonatal mortality in NICU. The score of 38 may be associated with higher mortality.

Assessment of control of bronchial asthma in children using Childhood Asthma Control Test.

BACKGROUND: The use of Childhood Asthma Control Test (C-ACT) has been advised for monitoring asthma control by the Global Initiative for Asthma (GINA) guidelines. OBJECTIVE: To validate the tool C-ACT for the assessment of control of asthma and to examine the correlation between C-ACT score and lung function assessed by forced expiratory volume in one second (FEV1). METHODS: This was a prospective observational study conducted between January 2010 to January 2011. Children diagnosed to have bronchial asthma and aged 5 to 14 years, were enrolled in the study. Asthma severity and control status were classified according to the National Asthma Education and Prevention Programme (NAEPP) and GINA guidelines, respectively. Patients were followed-up at three and six months and C-ACT and spirometric measurements were obtained. RESULTS: Significant positive correlations were found between C-ACT score and FEV1 at enrollment (r = 0.772) (p < 0.001), three months (r = 0.815) (p < 0.001) and at six months follow-up (r = 0.908) (p < 0.001). Baseline C-ACT score was useful for predicting the levels of control of asthma upto three months (0.004), but not at six months follow-up (0.787). A cut-off C-ACT value of > or = 19 had a sensitivity, specificity, positive predictive value, negative predictive value and area under the curve (AUC) 98.5%, 89.1%, 94.9%, 96.6%, 0.717, respectively for the control of asthma. CONCLUSION: C-ACT is a simple and feasible tool to assess and predict the levels of control in children with bronchial asthma upto three months.

The functional, social and economic impact of acute encephalitis syndrome in Nepal--a longitudinal follow-up study.

BACKGROUND: Over 133,000 children present to hospitals with Acute Encephalitis Syndrome (AES) annually in Asia. Japanese encephalitis (JE) accounts for approximately one-quarter of cases; in most cases no pathogen is identified and management is supportive. Although JE is known to result in neurological impairment, few studies have examined the wider impact of JE and AES on patients and their families. METHODOLOGY/PRINCIPAL FINDINGS: Children (aged 1 month-14 years) with AES were assessed 5-12 months after discharge from two Nepali hospitals. Assessment included clinical examination, the Liverpool Outcome Score (LOS) - a validated assessment of function following encephalitis, questionnaires about the child's social participation since discharge, and out-of-pocket costs to the family. Children were classified as JE or 'other AES' based on anti-JE virus antibody titres during acute illness. Contact was made with the families of 76% (73/96) of AES children. Six children had died and one declined participation. 48% (32/66) reported functional impairment at follow-up, most frequently affecting behaviour, language or limb use. Impairment was more frequent in JE compared to 'other AES' cases (68% [13/19] versus 40% [19/47]; p = 0.06). 49% (26/53) had improvement in LOS between discharge and follow-up. The median out-of-pocket cost to families, including medical bills, medication and lost earnings was US$ 1151 (10 times their median monthly income) for children with severe/moderate impairment and $524 (4.6 times their income) for those with mild/no impairment (P = 0.007). Acute admission accounted for 74% of costs. Social participation was limited in 21% of children (n = 14). CONCLUSIONS/SIGNIFICANCE: Prolonged functional impairment was common following AES. Economic impact to families was substantial. Encouragingly, almost half the children improved after discharge and most reported sustained social participation. This study highlights a need for long-term medical support following AES. Rationalisation of initial expensive hospital treatments may be warranted, especially since only supportive treatment is available.

Clinical and etiological profile of acute febrile encephalopathy in eastern Nepal.

OBJECTIVE: To investigate the clinical and etiological profile of acute febrile encephalopathy in children presenting to a tertiary care referral center of Eastern Nepal. METHODS: 107 children (aged 1 month to 14 yrs) presenting to the emergency with fever (> 38 C) of less than 2 weeks duration with altered sensorium with/or without seizure were prospectively investigated for etiological cause. The investigations included blood and CSF counts, blood and CSF cultures, peripheral smear and serology for malarial parasite, and serology for Japanese encephalitis (JE) virus. Other investigations included EEG and CT or MRI wherever indicated. RESULTS: The most common presenting complaints apart from fever and altered sensorium were headache and vomiting. Convulsions, neck rigidity, hypertonia, brisk deep tendon reflexes, extensor plantar response and focal neurological deficits were seen in 50%, 57%, 22.4%, 28%, 39.3% and 9.3% of the subjects, respectively. The diagnoses based on clinical presentation and laboratory findings were pyogenic meningitis in 45 (42%), non JE viral encephalitis in 26 (25%), JE in 19 (18%), cerebral malaria in 8 (7%), herpes encephalitis and tubercular meningitis in 4 (4%) each, and typhoid encephalopathy in 1 case. CONCLUSION: Pyogenic meningitis and viral encephalitis including JE are the most common causes of acute presentation with fever and encephalopathy. Preventive strategies must be directed keeping these causes in mind.
