Background: A strategy of administering a neonatal rotavirus vaccine at birth to target early prevention of rotavirus gastroenteritis may address some of the barriers to global implementation of a rotavirus vaccine.Methods: We conducted a randomized, double-blind, placebo-controlled trial in Indonesia to evaluate the efficacy of an oral human neonatal rotavirus vaccine (RV3-BB) in preventing rotavirus gastroenteritis. Healthy newborns received three doses of RV3-BB, administered according to a neonatal schedule (0 to 5 days, 8 weeks, and 14 weeks of age) or an infant schedule (8 weeks, 14 weeks, and 18 weeks of age), or placebo. The primary analysis was conducted in the per-protocol population, which included only participants who received all four doses of vaccine or placebo within the visit windows, with secondary analyses performed in the intention-to-treat population, which included all participants who underwent randomization.Results: Among the 1513 participants in the per-protocol population, severe rotavirus gastroenteritis occurred up to the age of 18 months in 5.6% of the participants in the placebo group (28 of 504 babies), in 1.4% in the neonatal-schedule vaccine group (7 of 498), and in 2.7% in the infant-schedule vaccine group (14 of 511). This resulted in a vaccine efficacy of 75% (95% confidence interval [CI], 44 to 91) in the neonatal-schedule group (P<0.001), 51% (95% CI, 7 to 76) in the infant-schedule group (P=0.03), and 63% (95% CI, 34 to 80) in the neonatal-schedule and infant-schedule groups combined (combined vaccine group) (P<0.001). Similar results were observed in the intention-to-treat analysis (1649 participants); the vaccine efficacy was 68% (95% CI, 35 to 86) in the neonatal-schedule group (P=0.001), 52% (95% CI, 11 to 76) in the infant-schedule group (P=0.02), and 60% (95% CI, 31 to 76) in the combined vaccine group (P<0.001). Vaccine response, as evidenced by serum immune response or shedding of RV3-BB in the stool, occurred in 78 of 83 participants (94%) in the neonatal-schedule group and in 83 of 84 participants (99%) in the infant-schedule group. The incidence of adverse events was similar across the groups. No episodes of intussusception occurred within the 21-day risk period after administration of any dose of vaccine or placebo, and one episode of intussusception occurred 114 days after the third dose of vaccine in the infant-schedule group.Conclusions: RV3-BB was efficacious in preventing severe rotavirus gastroenteritis when administered according to a neonatal or an infant schedule in Indonesia.

Background: Although both hemodialysis and continuous ambulatory peritoneal dialysis (CAPD) are covered by national healthcare insurance, 98% of kidney failure disease patients are treated with hemodialysis. This study compared the health-related quality of life (HRQoL) and utility scores of patients receiving hemodialysis and CAPD in Indonesia and determined factors associated with HRQoL and utility scores., Methods: A cross-sectional study was performed using the Kidney Disease Quality of Life-36 and EQ-5D-5L instruments at six hospitals. Utility scores were presented as SF-6D and EQ-5D scores. Factors associated with the EQ-5D were evaluated using Tobit regressions due to ceiling effects, while the SF-6D and HRQoL were assessed using generalized linear models since the data were not normally distributed., Results: Among the 613 patients, 76% were treated with hemodialysis. After adjusting for sociodemographic characteristics and clinical parameters, CAPD patients reported better HRQoL compared to hemodialysis patients in terms of the SF-6D ( p = .038), mental component summary ( p = .020), symptoms ( p = .005), and effects of kidney disease ( p <.001), but no significant differences were reported in EQ-5D ( p = .083), physical component summary ( p = .323), burden of kidney disease ( p = .111), and kidney summary scores ( p = .068). Poorer HRQoL and utility scores were likely experienced by older patients who were male, married, with diabetes, treated in Class A hospitals, and with lower education, hemoglobin, and albumin levels., Conclusion: In Indonesia, patients treated with CAPD had better HRQoL and utility scores compared to patients undergoing hemodialysis. Therefore, CAPD should be promoted by healthcare professionals as the first treatment option for patients who are eligible for both hemodialysis and CAPD., Competing Interests: Declaration of conflicting interestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: MJP and CB reported grants and honoraria from various pharmaceutical companies.

Background: Histo-blood group antigen (HBGA) status may affect vaccine efficacy due to rotavirus strains binding to HBGAs in a P genotype-dependent manner. This study aimed to determine if HBGA status affected vaccine take of the G3P[6] neonatal vaccine RV3-BB., Methods: DNA was extracted from stool samples collected in a subset (n = 164) of the RV3-BB phase IIb trial in Indonesian infants. FUT2 and FUT3 genes were amplified and sequenced, with any single-nucleotide polymorphisms analyzed to infer Lewis and secretor status. Measures of positive cumulative vaccine take were defined as serum immune response (immunoglobulin A or serum-neutralizing antibody) and/or stool excretion of RV3-BB virus. Participants were stratified by HBGA status and measures of vaccine take., Results: In 147 of 164 participants, Lewis and secretor phenotype were determined. Positive vaccine take was recorded for 144 (97.9%) of 147 participants with the combined phenotype determined. Cumulative vaccine take was not significantly associated with secretor status (relative risk, 1.00 [95% CI, .94-1.06]; P = .97) or Lewis phenotype (relative risk, 1.03 [95% CI, .94-1.14]; P = .33), nor was a difference observed when analyzed by each component of vaccine take., Conclusions: The RV3-BB vaccine produced positive cumulative vaccine take, irrespective of HBGA status in Indonesian infants., Competing Interests: Potential conflicts of interest.

Objectives: The aim of this review is to appraise and assimilate evidence from studies that have reported on the cost-effectiveness of screening programs for chronic kidney disease (CKD)., Methods: The study protocol was registered on International Prospective Register of Systematic Reviews (PROSPERO). The final search was conducted on 18 January 2023 using 7 databases. Screening of articles, data extraction, and quality assessment was performed by 2 independent reviewers. The ISPOR-AMCP-NPC checklist was used to assess the credibility of the included studies., Results: From 4948 retrieved studies, a final total of 20 studies were included in the qualitative synthesis. Studies found that screening in diabetic populations was cost-effective (n = 8, 57%) or even cost-saving (n = 6, 43%). Four studies (67%) found that screening in hypertensive populations was also cost-effective. For the general population, findings were inconsistent across studies in which many found screening to be cost-effective (n = 11, 69%), some cost-saving (n = 2, 12%), and others not cost-effective (n = 3, 19%). The most influential parameters identified were prevalence of CKD and cost of screening., Conclusions: Screening for CKD in patients with diabetes or hypertension is recommended from a cost-effectiveness point of view. For the general population, despite some inconsistent findings, the majority of studies demonstrated that screening in this population is cost-effective, depending mainly on the prevalence and the costs of screening. Healthcare decision makers need to consider the prevalence, stratification strategies, and advocate for lower screening costs to reduce the burden on healthcare budgets and to make screening even more favorable from the health-economic perspective., Competing Interests: Author Disclosures Prof Dr Postma reports grants and personal fees from Pharmacoeconomics Advice Groningen (PAG) B.V., grants and personal fees from Health-Ecore, outside the submitted work; Prof Dr Postma holds stocks in Health-Ecore and PAG B.V., all pharmacoeconomic consultancy companies.

ABSTRACT Although mammography is the gold standard for breast cancer screening, the World Health Organization recommends clinical breast examination (CBE) as the preferred early detection method in countries with limited resources. However, its effectiveness as a 'stand-alone' screening modality compared with other techniques remains unclear. Therefore, we evaluated a risk-based opportunistic breast cancer screening programme using three modalities. Between June and December 2018, we conducted a cross-sectional study in Yogyakarta, Indonesia, of women aged >40 years with at least one risk factor for breast cancer. Subjects underwent CBE, mammography, and ultrasonography. We calculated the proportion of breast lesions detected through each modality and compared their mass size. A total of 503 eligible subjects were screened. Five cases of potential malignant lesions were detected; pathological tests conducted for 4 of them confirmed breast cancer diagnoses. A combined assessment of mammography and ultrasonography examinations revealed 343 breast lesions (68.2%), whereas CBE screening detected only 76 breast lesions (15.1%). The mean lesion sizes detected by mammography or ultrasonography, but not through CBE, were significantly smaller ( p -values of 0.037 and 0.007 for mammography and ultrasonography, respectively). In conclusion, mammography and ultrasonography produced higher detection rates for benign and malignant breast lesions compared with CBE.

Background: Low- and middle-income countries (LMICs) have limited resources compared to high-income countries (HICs). Therefore, it is critical that LMICs implement cost-effective strategies to reduce the burden of breast cancer. This study aimed to answer the question of whether mammography is a cost-effective breast cancer screening method in LMICs., Methods: A systematic article search was conducted through Medline, Embase, Web of Science, and Econlit. Studies were included only if they conducted a full economic evaluation and focused on mammography screening in LMICs. Two reviewers screened through the title and abstract of each article and continued with full-text selection. Data were extracted and synthesized narratively. Quality assessment for each included study was conducted using the Consensus Health Economic Criteria (CHEC) extended checklist., Results: This review identified 21 studies economically evaluating mammography as a breast cancer screening method in LMICs. Eighteen of these studies concluded that mammography screening was a cost-effective strategy. Most studies (71%) were conducted in upper-middle-income countries (Upper MICs). The quality of the studies varied from low to good. Important factors determining cost-effectiveness are the target age group (eg, 50-59 years), the screening interval (eg, biennial or triennial), as well as any combination with other breast cancer control strategies (eg, combination with treatment strategy for breast cancer patients)., Conclusions: Mammography screening appeared to be a cost-effective strategy in LMICs, particularly in Upper MICs. More studies conducted in lower-middle-income and low-income countries are needed to better understand the cost-effectiveness of mammography screening in these regions., Competing Interests: Competing interests: The authors completed the ICMJE Unified Competing Interest Form (available upon request from the corresponding author) and declare no conflicts of interest., (Copyright © 2022 by the Journal of Global Health.

Background: Breast cancer is the deadliest cancer among women worldwide including Indonesia. Both FAC and Taxane-based chemotherapies are often used for patients with early node-positive breast cancer. However, the study regarding the cost-effectiveness of those regiments is still rare. This study aims to analyze the cost-effectiveness of Taxane versus FAC in the Indonesia setting., Methods: Twenty-four patients with stage I-IIIA breast cancer who had received surgery, FAC or Taxane-based adjuvant chemotherapy, and radiation were included in this study. Health-related quality of life was assessed using INA-BCHRQoL. INA-BCHRQoL was mapped to the EuroQoL 5D (EQ-5D) index calculator to get the utility score. All direct cost was retrieved from electronic medical records and hospital information system. Whereas, a questionnaire was designed to collect information about society cost from patients. ICER was counted to summarize the cost-effectiveness of two chemotherapy regiments (Taxane versus FAC). A sensitivity analysis was done to assess the uncertainty result., Results: The results showed there was no significant difference between the score of quality of life and utility in respondents who received FAC chemotherapy and Taxane-based chemotherapy. However, in terms of cost, Taxane was 6.5 times higher than the FAC group per patient for chemotherapy drugs only. Moreover, the total cost of treatments in Taxane-based chemotherapy was approximately 3.7 times more costly than the counterpart in the FAC arm (p=0.000). Taxane-based chemotherapy dominated with ICER IDR 765.213.092 per QALY gained. Overall, FAC was found more cost-effective compared to the Taxane regiment., Conclusion: FAC represents the value of money compared to Taxane-based for breast cancer patients with stage I-IIIA in Indonesia.

Background: Diarrhea remains a major cause of child morbidity and mortality in low- and middle-income countries. Reliable data on the economic burden of diarrhea is required to support the selection of appropriate health intervention programs. This study aimed to estimate the costs of acute diarrhea in children under five years of age in Indonesia, a large middle-income country with a substantial diarrheal burden., Methods: Direct medical cost data were extracted retrospectively for 1050 children under five years of age with acute diarrhea receiving inpatient care across 45 health facilities in seven Indonesian provinces during 2017-2020. Direct medical costs for children treated in outpatient settings were estimated by collecting unit costs associated with standard diarrhea case management in children. A structured interview of 240 caregivers of inpatients was also conducted retrospectively to estimate direct non-medical costs as well as indirect costs from caregiver income loss., Results: The weighted average direct medical cost for treatment of acute diarrhea as an inpatient and outpatient across health facility types was US$99.8 (SD±$56.8)(35% room costs, 29% professional fees, 26% medication costs, 10% diagnostic costs) and US$7.6 (SD±$4.3) (34% diagnostic costs, 28% medication costs, 27% professional fees, 10% registration fees), respectively. The average direct non-medical household cost for an acute diarrheal admission was US$4.90 and the indirect cost was US$9.90., Conclusion: There is a significant economic burden associated with acute diarrhea in children in Indonesia. This study, based on a wide variety of health care settings and geographical regions, provides data to inform the economic evaluation of rotavirus vaccines and other diarrheal prevention programs., Funding: This work was supported by a research grant from the Murdoch Children's Research Institute (MCRI) and PATH; and the Indonesian Technical Advisory Group on Immunization (ITAGI)., Competing Interests: JEB and EW are employed as researchers at MCRI. All other authors do not have an association that might pose a conflict of interest., (© 2021 Published by Elsevier Ltd.)

Background: Despite safe and effective WHO prequalified rotavirus vaccines, at least 84 million children remain unvaccinated. A birth dose schedule of the RV3-BB vaccine was reported to be highly efficacious against severe rotavirus disease in Indonesian infants and is under further development at PT Bio Farma, Indonesia. The aim is to develop a rotavirus vaccine starting from birth that could improve the implementation, safety, and effectiveness of vaccines., Methods: A multi-site phase I study of a human neonatal RV3 rotavirus vaccine (Bio Farma) in adults, children, neonates in Indonesia from April 2018 to March 2019. The adult and child cohorts were open-labeled single-dose, while the neonatal cohort was randomized, double-blind, and placebo-controlled three-doses at the age of 0-5 days, 8-10 weeks, and 12-14 weeks. The primary objective was to assess the safety of vaccines with the immunogenicity and vaccine virus fecal shedding as the secondary endpoints in neonates., Results: Twenty-five adults, 25 children, and 50 neonates were recruited, and all but one in the neonatal cohort completed all study procedures. Three serious adverse events were reported (1 adult & 2 neonates), but none were assessed related to investigational product (IP). The neonatal vaccine group had a significantly higher positive immune response (cumulative seroconverted SNA and IgA) 28 days after three doses than those in the placebo group (72% vs. 16.7%, respectively). The GMT of serum IgA in the vaccine group was significantly higher at post IP dose 1 (p < 0.05) and post IP dose 3 (p < 0.001) compared to the placebo group., Conclusion: The trial results show that the RV3 rotavirus vaccine (Bio Farma) is well tolerated in all participant cohorts (adults, children, and neonates). Three doses of this vaccine administered in a neonatal schedule were immunogenic. These promising results support further clinical development of the RV3 rotavirus vaccine (Bio Farma)., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: [J.F., R.M.S. and N.S.B. are employees of PT Bio Farma who provided funds to support this study and plan to manufacture RV3 rotavirus vaccine (Bio Farma).

Background: Rational medication use for treatment is mandatory, particularly in children as they are vulnerable to possible hazards of drugs. Understanding the medication use pattern is of importance to identify the problems of drug therapy and to improve the appropriate use of medication among this population., Methods: A post-hoc study of the RV3-BB Phase IIb trial to children aged 0-18 months which was conducted in Indonesia during January 2013 to July 2016. Any concomitant medication use and health events among 1621 trial participants during the 18 months of follow-up were documented. Information on medication use included the frequency, formulation, indication, duration of usage, number of regimens, medication types, and therapeutic classes., Results: The majority of participants (N = 1333/1621; 82.2%) used at least one non-antibiotic medication for treatment during the 18-month observation period. A total of 7586 medication uses were recorded, mostly in oral formulation (90.5%). Of all illnesses recorded, 24.7% were treated with a single drug regimen of non-antibiotic medication. The most common therapeutic classes used were analgesics/antipyretics (30.1%), antihistamines for systemic use (17.4%), cough and cold preparations (13.5%), vitamins (8.6%), and antidiarrheals (6.6%). The main medication types used were paracetamol (29.9%), chlorpheniramine (16.8%), guaifenesin (8.9%), zinc (4.6%), and ambroxol (4.1%). Respiratory system disorder was the most common reason for medication use (51.9%), followed by gastrointestinal disorders (19.2%), pyrexia (16.9%), and skin disorders (7.0%)., Conclusion: A large number of children were exposed to at least one medication during their early life, including those where evidence of efficacy and safety in a pediatric population is lacking. This supports the need for further research on pediatric drug therapy to improve the appropriate use of medication in this population., Competing Interests: The authors have the following interests: NSB is a paid employee of PT Biofarma. PT Biofarma is a state-owned company (owned by Indonesia government) that provides all vaccines for Indonesia National Immunization Program. Additionally, PT Biofarma was one of the non-commercial funders for the RV3-BB Phase IIB trial. No consultation was done to the funder relating to the trial. The trial was a phase IIB trial and while the RV3-BB rotavirus vaccine is not yet marketed, this vaccine is being developed with the intention for eventual usage in the national immunization program. This does not alter our adherence to PLOS ONE policies on sharing data and materials.

Background: Placental or breast milk maternal antibodies can potentially reduce oral rotavirus vaccine efficacy in developing countries. We aimed to examine the relationship between the level of rotavirus specific immunoglobulin A (IgA) and neutralising antibodies (NA) in colostrum and breast milk and cord IgG, with cumulative vaccine take following one and three doses of oral RV3-BB rotavirus vaccine within a Phase IIb trial in Indonesia., Methods: 196 infants received three doses of RV3-BB in a randomized, double-blinded trial, using a neonatal schedule (first dose at 0-5 days of age, n = 61), an infant schedule (first dose at ~ 8 weeks of age, n = 67) or placebo (n = 68). Rotavirus specific IgA and NA in colostrum and breast milk, rotavirus specific cord IgG, Serum IgA and stool excretion were measured., Results: There was little evidence of an association between IgA in colostrum or breast milk and cumulative vaccine take after three doses in the neonatal or infant groups. In the neonatal group, there was a negative association between IgG titre in cord blood and cumulative vaccine take (odds ratio [OR] 0.96; 95% confidence interval [CI] 0.92-1.00; p = 0.03) and serum IgA response (OR 0.94; 95%CI 0.89-0.99; p = 0.02) after one dose of vaccine, which were not evident after three doses in the neonatal or infant groups., Conclusions: Amongst Indonesian infants we did not find an association between IgA in colostrum or breast milk and vaccine take after 3 doses of RV3-BB vaccine. Maternal rotavirus antibodies in breast milk appear to have minimal impact on RV3-BB vaccine take when administered with a short delay in breast-feeding in settings with a high rotavirus disease burden., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd.

Background: The RV3-BB human neonatal rotavirus vaccine was developed to provide protection from severe rotavirus disease from birth. The aim of this study was to investigate the potential for mutual interference in the immunogenicity of oral polio vaccine (OPV) and RV3-BB., Methods: A randomized, placebo-controlled trial involving 1649 participants was conducted from January 2013 to July 2016 in Central Java and Yogyakarta, Indonesia. Participants received three doses of oral RV3-BB, with the first dose given at 0-5 days (neonatal schedule) or ~8 weeks (infant schedule), or placebo. Two sub-studies assessed the immunogenicity of RV3-BB when co-administered with either trivalent OPV (OPV group, n = 282) or inactivated polio vaccine (IPV group, n = 333). Serum samples were tested for antibodies to poliovirus strains 1, 2 and 3 by neutralization assays following doses 1 and 4 of OPV., Results: Sero-protective rates to poliovirus type 1, 2 or 3 were similar (range 0.96-1.00) after four doses of OPV co-administered with RV3-BB compared with placebo. Serum IgA responses to RV3-BB were similar when co-administered with either OPV or IPV (difference in proportions OPV vs IPV: sIgA responses; neonatal schedule 0.01, 95% CI -0.12 to 0.14; p = 0.847; infant schedule -0.10, 95% CI -0.21 to -0.001; p = 0.046: sIgA GMT ratio: neonatal schedule 1.23, 95% CI 0.71-2.14, p = 0.463 or infant schedule 1.20, 95% CI 0.74-1.96, p = 0.448)., Conclusions: The co-administration of OPV with RV3-BB rotavirus vaccine in a birth dose strategy did not reduce the immunogenicity of either vaccine. These findings support the use of a neonatal RV3-BB vaccine where either OPV or IPV is used in the routine vaccination schedule., (Copyright © 2019 The Authors. Published by Elsevier Ltd..

Background: Antimicrobial resistance has become a global health emergency and is contributed to by inappropriate antibiotic use in community clinical settings. The aim of this study was to evaluate the antimicrobial use pattern in infants from birth until 18 months of age in Indonesia., Methods: A post-hoc analysis was conducted in 1621 participants from the RV3BB Phase IIb trial conducted in Indonesia from January 2013 through July 2016. Any health events were documented in the trial as adverse events. Concomitant medication surveillance recorded all medications, including antibiotics during the 18 months of follow-up. Information included the frequency, duration of usage, formulation, classes, and their indications, including prophylactic antibiotic and perinatal use., Results: Of 1621 participants, 551 (33.99%) received at least one antibiotic for treatment of infections during the 18 months observation period. Additionally, during the perinatal period, prophylactic antibiotics were used in 1244 (76.74%) participants and antibiotics consumed in 235 mothers of participants (14.50%). A total of 956 antibiotic consumptions were recorded for 18 months follow up, 67 (7.01%) as part of antimicrobial combinations. The average duration of antibiotic course was 4.92 days. Penicillin and sulfonamides were the most common antibiotic classes consumed (38.81% and 24.48%, respectively)., Conclusions: Despite the low community consumption rate, the overuse of antibiotic in URTIs and non-bloody diarrhea in our setting represents a major opportunity for antimicrobial stewardship, particularly in early life., Competing Interests: The authors have the following interests: NSB is a paid employee of PT Biofarma. PT Biofarma is a state-owned company (owned by Indonesia government) that provides all vaccines for Indonesia National Immunization Program. Additionally, PT Biofarma was one of the funders for the RV3-BB Phase IIB trial. The trial was a phase IIB trial and while the RV3-BB rotavirus vaccine is not yet marketed, this vaccine is being developed with the intention for eventual usage in the national immunization program.
