Diarrhea among hospitalized children under five: A call for inclusion of rotavirus vaccine to the national immunization program in Indonesia.

CONTEXT: Rotavirus diarrhea is a common disease worldwide which mostly affects children under five years old. Rotavirus infection causes severe diarrhea and leads to substantial health care costs. In Indonesia the rotavirus vaccine has been available since 2011, however it has not been included into the National Immunization Program. This study aims to describe the proportion of rotavirus in children under 5 in Indonesia, the clinical characteristics of rotavirus infections, and the rotavirus strains circulating in the country during 2010-2015. METHODS: Children under five years of age with acute watery diarrhea were prospectively identified and enrolled through the active diarrhea surveillance system in 5 sites in four provinces in Indonesia during 2010-2015. The rotavirus specimens were tested using Enzyme Immunoassay. Bivariate logistic regression tests were performed to compare rotavirus positive and negative results with respect to the collected demographic and clinical variables. RESULTS: From January 2010 to December 2015, the average annual rotavirus prevalence among children hospitalized with acute watery diarrhea in four provinces in Indonesia was 47.5%. Rotavirus diarrhea occurred mostly in children under 2 years of age. Of all age groups, children aged 6-11 and 12-23 months had the highest prevalence of rotavirus diarrhea in all years (54.2% and 50.6%, respectively). This study found that the most prevalent of G and P genotypes were G1P8 in 2010 (63.2%), 2011 (64.1%) and 2012 (74.6%) and G3P8 in 2013 (49.7%), 2014 (82.5%) and 2015 (84.4%) CONCLUSIONS: This study demonstrates that rotavirus is a major cause of diarrhea in hospitalized children in Indonesia. These findings highlight the need for inclusion of the rotavirus vaccine to the National Immunization Program in Indonesia.

Liver transplant score for prediction of biliary atresia patients' survival following Kasai procedure.

OBJECTIVES: Recently, a scoring system has been developed to predict which patients with biliary atresia (BA) who underwent a Kasai procedure should be considered for liver transplant. Here, we applied the scoring system to predict the survival of BA patients following the Kasai procedure at Dr. Sardjito Hospital, Yogyakarta, Indonesia from January 2012 to January 2016. RESULTS: There were 26 patients, of whom 14 were males and 12 females. Outcomes of BA patients after the Kasai surgery were 15 survived and 11 died. There were significant associations between ascites and sepsis with the liver transplant score of ≥ 8 (p value = 0.006 and 0.014, respectively), whereas post-operative bilirubin level, ALT level, prothrombin time, cirrhosis, esophageal varices, portal hypertension, and cholangitis did not significantly correlate to the score. The patients with a score ≥ 8 have a relatively greater risk by 3.5-fold to die compared with patients with a score < 8, but it did not reach a significant level (p value = 0.13). In conclusions, the incidence of ascites and sepsis might predict the poor prognosis of BA patients following the Kasai procedure. Moreover, patients with a score ≥ 8 are prone to die after the Kasai surgery if they do not undergo a liver transplant.

Efficacy of Hepatitis B Vaccination among Children in Special Region of Yogyakarta, Indonesia: Evaluation of Humoral and Cellular Immunity.

Hepatitis B remains a global burden, with estimated 15 to 40 percents of infected individuals eventually suffer from liver cirrhosis, liver failure, and hepatocellular carcinoma. Vaccination aims to form anti-HBs antibody with protective titer to prevent infection. CD4 T cell lymphocytes are known to play a major role in establishing immunity after vaccination. This study aimed to investigate protective titer rate among Indonesian children in Special Region of Yogyakarta following hepatitis B vaccination and correlation between anti-HBs titer and CD4 count. This is a cross-sectional study with 52 subjects between 8 months to 5 years of age in Bungas Community Health Service, Special Region of Yogyakarta, Indonesia. Anti-HBs titer was examined using enzyme immunoassay and CD4 count was examined using immunocytochemistry method. Of 52 subjects, median anti-HBs titer was 72.965 IU/L (interquartile range 360.98), mean CD4 count was 49.73% ± 29.75. Protective level of antibody was found in 73.1% of subjects. Correlation test was conducted and no correlation was found between anti-HBs titer and CD4 count (r=-0.104, p=0.464). Age was found to have a weak negative correlation with anti-HBs titer (r=-0.367, p=0.007). We found high rate of protective titer among children in Special Region of Yogyakarta who have completed hepatitis B vaccination series. No correlation was established between anti-HBs titer and CD4 count.
