Pneumococcal nasopharyngeal carriage in Indonesia infants and toddlers post-PCV13 vaccination in a 2+1 schedule: A prospective cohort study.

BACKGROUND: The PCV13 immunization demonstration program began in October 2017 in Indonesia. The aim of this study is to assess the dynamic changes of pneumococcal serotype before and after PCV13 administration, with two primary and one booster doses. METHODS: The prospective cohort study was conducted as a follow up study measuring the impact of PCV13 demonstration program by the Indonesian Ministry of Health in Lombok Island, West Nusa Tenggara, Indonesia, from March 2018 to June 2019. The subjects were two-month-old healthy infants who were brought to the primary care facility for routine vaccination and followed until 18 months of age. We use convenience sampling method. There were 115 infants in the control group and 118 infants in the vaccine group, and the PCV immunization was given on a 2+1 schedule. Nasopharyngeal (NP) swabs were collected four times during the vaccination periods by trained medical staff. Specimens were analyzed by culture methods to detect S. pneumonia colonization and multiplex polymerase chain reaction (mPCR) to determine serotype. The most frequently detected serotypes will be named as dominant serotypes. Descriptive analysis of demographic characteristics, the prevalence of overall and serotype colonization, and the distribution of serotypes were performed. The prevalence of both cohort groups were compared using chi-square test. Statistical significance was set at p < 0.05. RESULTS: Two hundred and thirty three infants age two months old were recruited, with 48.9% of the subjects were male and 51.1% of the subjects were female. Sociodemographic data in both cohort groups were relatively equal. Nasopharyngeal pneumococcal colonization before PCV13 administration occurred in 19.1% of the control and 22.9% of the vaccine group. The prevalence increased with increasing age in both groups. The prevalence of VT serotypes in control groups aged 2 months, 4 months, 12 months, and 18 months was 40.9%, 44.2%, 53.8%, and 54.3%, respectively, and in the vaccine group, 25.9%, 40.4%, 38.0%, and 22.6%, respectively. The most common VT serotypes in both groups were 6A/6B, 19F, 23F, and 14. The prevalence of VT serotypes decreased significantly compared to non-vaccine type serotypes after three doses of the PCV13 vaccine (p < 0.001). Another notable change was the decline in prevalence of serotype 6A/6B after PCV13 administration using the 2+1 schedule. CONCLUSIONS: This study shows lower prevalence of VT and 6A/6B serotypes in the nasopharynx among children who were PCV13 vaccinated compared with those who were unvaccinated. The result from this study will be the beginning of future vaccine evaluation in larger population and longer period of study.

Knowledge and healthcare-seeking behavior of family caregivers of children with pneumonia: A qualitative study in an urban community in Indonesia.

Background: Childhood pneumonia is the leading cause of death. Family caregivers may have a poor understanding of pneumonia, especially related to prevention and treatment. It is crucial to understand country-specific knowledge and healthcare-seeking behaviors of caregivers of children with pneumonia before planning programmatic responses, particularly in an urban community where the culture-social economic status is diverse. Objective: This study aimed to describe the knowledge and healthcare-seeking behavior of family caregivers of children with pneumonia in Indonesia's urban community. Methods: A descriptive qualitative study was conducted at a public hospital in Jakarta, Indonesia, from 10 December 2019 to 28 January 2020. Ten family caregivers of children with pneumonia were included, and a semi-structured interview was conducted for data collection. The audio recording was transcribed verbatim, and the data were analyzed using content analysis. Results: The emerged data indicated low knowledge of the family caregivers, especially mothers, which considered pneumonia a common cold only, and they failed to understand the risk of its transmission. Using traditional medicines was the first stage of healthcare-seeking behavior. If the symptoms worsened, the caregivers brought their children to the nearest health center. If there was no change in the symptoms, they headed to the hospital. The health center's location, condition, services, and staff attitude were considered factors to choose the services. Conclusion: Living in an urban area does not guarantee the family caregivers have better knowledge and good healthcare-seeking behavior. Therefore, nurses should provide comprehensive education about pneumonia, its symptoms, and treatment management to improve family care and prevent pneumonia-related deaths. Integrated management of children with illness is recommended to help the family caregivers of children with pneumonia receive treatment as quickly as possible.

Asymptomatic proteinuria in Indonesian adolescent students.

Proteinuria is one of the common manifestations of kidney disease that has a serious impact on the progressive deterioration of kidney function. In developed countries, school screening for asymptomatic proteinuria is routinely performed, especially in adolescent students, to detect early stage of chronic kidney disease. This study aimed to find out the prevalence of asymptomatic persistent proteinuria in adolescent students. This was a multi-assessment study. Screening for proteinuria was conducted on five junior high schools across Jakarta, Indonesia, in April-June 2015. Healthy students aged 12-14 years whose parents provided informed consent were selected randomly. Urine collections were performed thrice. We used dipstick tests and protein-to-creatinine ratio to measure protein in the urine. From 536 students, 485 were eligible and recruited for this study. They were more female and well-nourished students. Hypertension constituted 12.9% of students. Proteinuria accounted for 7.42%. Transient, orthostatic, and persistent proteinuria were found in 5.77%, 1.03%, and 0.62% of students, respectively. The prevalence of asymptomatic persistent proteinuria among adolescent students in Jakarta is higher than that in other populations in Asia. Consequently, a routine screening to detect proteinuria should be considered in Indonesia to detect chronic kidney disease in children.

Vitamin D status in under-five children with a history of close tuberculosis contact in Padang, West Sumatra.

BACKGROUND AND OBJECTIVE: Serum vitamin D influences cellular immunity against Mycobacterium tuberculosis, particularly in under-five children. Vitamin D insufficiency and deficiency as well as tuberculosis (TB) are highly prevalent in Indonesia. This study described the association of serum vitamin D in the incidence of latent TB in under-five children with a history of close TB contact. METHODS AND STUDY DESIGN: This cross-sectional study examined 178 under-five children with a history of close TB contact, with 98 index cases from primary health care facilities in Padang. Latent TB was defined based on a positive tuberculin skin test. Serum vitamin D was determined using ELISA method. General characteristics for age, sex, socioeconomic status, contact score, BCG scars, and nutritional status were also collected. RESULTS: Of 168 eligible subjects, 40.5% had latent TB, however no differences between 'latent TB' and 'without latent TB' were observed in participant characteristics. Vitamin D deficiency, insufficiency, and sufficiency were observed in 23.3%, 43.5%, and 33.3% of children, respectively. In general, the 'latent TB' group had lower serum vitamin D than those in the 'without latent TB' group, stratified by age, contact score and nutritional status; however, significant differences were observed in children age <1 years (18.0±2.6 vs 31.2±10.5, respectively, p=0.013). Nevertheless, no associations between the two groups were observed using multivariate analysis. CONCLUSION: Vitamin D status was not associated with the incidence of latent TB among under-five children with a history of close TB contact, although this may not obtain in children aged <1 year old.

Invasive pneumococcal disease among hospitalized children aged 28 days to 60 months in Jarkarta.

Streptococcus pneumoniae is a leading cause of morbidity and mortality among children worldwide. Prevention of invasive pneumococcal disease (IPD) with a pneumococcal conjugate vaccine (PCV) is an effective approach to reduce the burden of pneumococcal disease. Nationwide epidemiological data is required prior to considering universal pneumococcal immunization for Indonesia. This preliminary study aimed to quantify the burden of IPD among hospitalized children at Cipto Mangunkusumo Hospital and Fatmawati Hospital, Jakarta. We studied 205 subjects aged 28 days to 60 months who were admitted with the diagnosis of pneumonia, meningitis, sepsis, and suspected occult bacteremia. Streptococcus pneumoniae was isolated from 1 of 205 blood specimens, giving an IPD proportion of 0.5%. The IPD case in this study was a 3-month-old baby with meningitis and bilateral lobar pneumonia. The Quellung test demonstrated serotype 7F. The isolate was susceptible to amoxicillin and Cotrimoxazole. Incidence of IPD could not be calculated due to low number of cases; this underscores the importance of surveillance of pneumococcal disease in Indonesia.

Risk factors of obstructive sleep apnea syndrome in obese early adolescents: a prediction model using scoring system.

AIM: to obtain the OSAS prevalence and risk factors of OSAS in obese early adolescents and to create a scoring system based on risk factors for diagnosing OSAS. METHODS: an observational study in Jakarta, November 2007 until December 2008 on obese adolescents aged 10-12 years with snoring. Subjects underwent clinical examination, lung function test, paranasal sinus X-ray, and polisomnography. Measured outcomes were diagnosis of OSAS; sensitivity, specificity, predictive values, and likelihood ratios of a scoring system based on risk factors. RESULTS: the prevalence of OSAS in obese early adolescents is 38.2% using AHI cut-off point of ≥3 on PSG. Tonsillar hypertrophy, adenoid hypertrophy, and neck circumference were the main risk factors. Scoring system was designed based on these results: OS= T + A + NC; OS= OSAS score; T= tonsil hypertrophy (≥T3 scored 1,
