Childhood Intussusception after Introduction of Indigenous Rotavirus Vaccine: Hospital-Based Surveillance Study from Odisha, India.

OBJECTIVE: To study the epidemiology of intussusception in children < 2 y of age, postintroduction of Rotavac® (an indigenous oral rotavirus vaccine). METHODS: A multicenter hospital-based surveillance was conducted in Odisha from February 2016 to June 2019. The cases were diagnosed according to Brighton level-1 criteria. Data were collected regarding the time of onset, signs and symptoms, radiological diagnosis, management, complications, and outcome (discharged/died). RESULTS: One hundred and twenty children < 2 y of age were enrolled. The median age was 7 mo (M:F ratio = 2:1). The most common clinical feature was abdominal distention and blood in stool. The most common method for treatment was hydrostatic/pneumatic reduction. Median time (days) between symptom onset and admission was 2. Median (IQR) duration (days) of hospitalization was 5. Most common location of intussusceptions was ileo-colic. CONCLUSIONS: Hydrostatic/pneumatic reduction was possible in the majority presenting ≤ 48 h of symptom onset, and those presenting > 48 h mostly required surgical reduction. Intestinal resection was required in some cases presenting on day 5 of symptom onset. Majority of cases were managed by surgical reduction in Government facility.

Clinical Profile, Risk-Factors, and Outcome of Rotaviral Diarrhea and Non-rotaviral Diarrhea Among Under-Five Children at Cuttack, Odisha, India.

OBJECTIVE: To understand the prevalence of rotavirus diarrhea and its associated clinical and socio-demographic characteristics. METHODS: The prospective hospital-based study was conducted at SVP Post Graduate Institute of Pediatrics and SCB Medical College, Odisha, India among children under-five years of age from April 2016 to July 2019. From all eligible children admitted at hospital, a case-report form containing information on clinical and socio-demographic characteristics was collected and an attempt was made to collect stool sample. A simple logistic regression method was used to assess factors associated with rotavirus diarrhea. RESULTS: Of the 1963 children, median (IQR) age was 12 (8-19) mo with a female/male ratio was 1:2.05. The prevalence of rotavirus diarrhea was 36.4% (95% CI, 34.2%-38.6%). Children in the age group of 6-11 (OR 1.64, 95% CI, 1.24-2.18), 12-23 (OR 1.73, 95% CI, 1.31-2.29) mo had higher odds of getting rotavirus diarrhea, compared to those in that of 24-59 mo. The prevalence of wasting, stunting, underweight among children with rotavirus diarrhea was 25.2% (95% CI, 22%-28.4%), 2.1% (95% CI, 1.1%-3.1%), 9.0% (95% CI, 6.8%-11.2%), respectively. CONCLUSION: The results of this study confirmed that diarrhea remains an important cause of hospitalization in children. Further studies are required in the community for Rotavirus and its genotyping.

Genetic Characteristics of Rotavirus Acute Gastroenteritis Among Hospitalized Children of Odisha in Eastern India.

OBJECTIVE: To generate epidemiological data of rotavirus diarrhea among hospitalized children less than 5 y of age and to characterize the circulating rotavirus genotypes post introduction of rotavirus vaccine in Universal Immunization Program (UIP). METHODS: This prospective study was conducted from April 2016 to July 2019 at Sardar Vallabhbhai Patel Post Graduate Institute of Paediatrics & SCB Medical College, Cuttack, Odisha among hospitalized children with acute gastroenteritis (AGE) under five years of age. Stool samples collected were tested for rotavirus by a commercial enzyme immunoassay and strains were characterized by reverse-transcription polymerase chain reaction (PCR). The data was analysed using a chi-square test with 95% confidence interval and risk ratio. RESULTS: Rotavirus diarrhea was seen in 715 (36.4%) of the 1963 samples tested. The peak incidence of rotavirus diarrhea was during the winter season, i.e., from the month of December to February. Most of the infections were in children between 6 mo to 2 y of age, affecting boys and girls equally. The commonest genotypes were G3P[8] (50.34%) followed by G1P[8] (17.46%). CONCLUSION: This study highlights the high prevalence of rotavirus diarrhea among children which emphasize the need for continued rotavirus vaccination. The changing patterns of genotype distribution stress the need for continued surveillance post introduction of vaccines to understand the effect of vaccines on strain evolution over a longer period and detect emergence of new genotypes.

Clinical Feature and Outcome of Childhood Status Epilepticus in a Teaching Hospital, Odisha, India.

Objectives The main aim is to find out the clinical feature and outcome of status epilepticus (SE) in children managed in a teaching hospital. The secondary aim is to identify the risk factors influencing the adverse outcomes. Methods In this prospective cohort, children aged 1 month to 14 years with SE as per the International League Against Epilepsy's new guideline (2016) who presented to the emergency department during the period of November 2017 to October 2019 were enrolled. Clinical profile, treatment, and outcome of cases (n = 94) were noted. Results The majority of children, 60 (63.82%), were less than five years of age. Prior history of seizures was present in 33 (35.1%) cases, whereas 61 (64.9%) cases presented with SE as the first episode of seizure. In 14 (42.4%) previous seizure cases, SE was due to drug default. No response to first-line antiepileptic drug (AED) was seen in 84 (89.37%) cases. Acute symptomatic etiology was the commonest etiology of SE in 64 (68%) cases, of which neuro-infections accounted for 44 (46.80%) cases. Longer duration (>60 minutes) of status (p < 0.01), ventilator support (p < 0.0001), and circulatory impairment (p < 0.0001) were attributable risk factors for mortality. A total of 28 children died (mortality rate, 29.8%), and 11 showed the persistence of their neuro-deficit. Conclusions Neuro-infection is the most common etiology of SE in children. Longer duration of SE, more lag time for receiving the first AED, respiratory failure, and presence of shock are independent predictors for poor outcome. Hence, cessation of convulsion at the earliest leads to improved outcomes.
