Abstract

Background Autoimmune thyroiditis may manifest as overt hypothyroidism, subclinical hypothyroidism, euthyroidism, or hyperthyroidism in children. Although there is no consensus on treating euthyroidism and autoimmune thyroiditis in children, some studies have demonstrated the efficacy of levothyroxine in reducing thyroid volume, improving thyroid function, and stabilizing the immunological process. Objective To determine the effect of levothyroxine on thyroid gland volume changes, thyroid function, and thyroid antibodies in euthyroid children with autoimmune thyroiditis. Methods We performed a literature search of electronic databases (the Cochrane Library, MEDLINE, EBSCO, ProQuest, clinicaltrials.gov, and other sources, as well as a non-electronic search (searching journals and conference proceedings by hand) to identify studies of euthyroid children with autoimmune thyroiditis published by August 2018. Only English-language articles were included in the search (electronic and non-electronic). Randomized controlled trials that compared levothyroxine with a control (placebo or no treatment) in euthyroid children with autoimmune thyroiditis were selected. The outcome measures were thyroid volume changes, thyroid function, and thyroid antibody levels in euthyroid children with autoimmune thyroiditis. Two authors independently extracted the data, assessed the risk of bias, and analyzed the pooled data from the included studies using a random effects model. The same authors performed a sensitivity analysis. Results We identified 57 studies. Of these, three studies, involving 97 subjects (51 subjects in an intervention group and 46 subjects in the control group) were selected for inclusion in a systematic review/meta-analysis. The meta-analysis revealed a significant difference in mean thyroid volume changes between the two groups (-1.10 SDs; 95%CI -1.56 to -0.64; P<0.0001; I2=6%). The mean difference in the thyroid-stimulating hormone (TSH) change of the two groups was -1.82 mU/L (95%CI -3.52 to -0.11; I2=87%; P=0.04). The standardized mean difference in free thyroxine (fT4) change of the two groups was 0.82 pmol/L (95%CI -1.14 to 2.78; I2=89%; P=0.41). Conclusion In euthyroid children with autoimmune thyroiditis, levothyroxine treatment reduces the thyroid volume better. The TSH level change in the intervention group is better than those in the control group. Levothyroxine treatment did not significantly improve free T4.

Abstract

Background Dengue infection is still rising globally despite the implementation of preventive efforts in many endemic countries. Monitoring the circulation of dengue virus (DENV) serotypes is not performed routinely in the Indonesian national surveillance program, primarily due to high cost and effort. Objective To evaluate the distribution of DENV serotypes based on serological profile and neutralizing antibody level against all four DENV serotypes in Jakarta, Indonesia. Methods This cross-sectional study was performed as part of a dengue vaccine effectiveness study, 10 years after a dengue vaccination program was initiated. It was conducted in five community public health centers in Jakarta in subjects aged 12 years and above who had not received the dengue vaccine. We collected serum samples and DENV neutralizing antibody titers were measured using a plaque reduction neutralization test (PRNT). Results Eighty healthy subjects with a median age of 15 (range 12-27) years were enrolled. The highest median antibody titer was that to DENV-2 [898 (range 29-91558) 1/dil], followed by that to DENV-3 [297.5 (range 10-36091); 1/dil], DENV-1 [288 (range 0-68237) 1/dil], and DENV-4 [164 (range 0-35812) 1/dil]. Neutralizing antibodies against the four DENV serotypes were found in all the 5 districts studied in Jakarta. A multitypic neutralizing antibody profile was observed in the majority (74/80 subjects; 92.5%). Three subjects were naïve. Conclusion All four dengue serotypes are widely circulating in Jakarta based on neutralizing antibody detection in the community, with the highest neutralizing antibody titer being against DENV-2, followed by DENV-3, DENV-1 and DENV-4.

Abstract

Background The Indonesian COVID-19 immunization program has provided primary doses of a COVID-19 vaccine to adolescents and adults, while booster doses were given to adults only. Evaluation of this program is crucial to determine if boosters should be recommended for adolescents. Objective To compare COVID-19 incidence and SARS-CoV-2 IgG neutralizing antibody levels after COVID-19 vaccination in adolescents given a primary dose vs. adults given a primary dose and a booster. Methods: In this cross-sectional study, participants were given questionnaires on their COVID-19 history and evaluated for SARS-CoV-2 IgG neutralizing antibody titers. We included healthy individuals aged 12 years or older who resided in Jakarta and consented to participate, had received primary COVID-19 vaccine doses, and for adults, booster doses. Participants were stratified into two age groups, adolescents (12-17 years) and adults (18 years and above). We compared the incidence of COVID-19 and SARS-CoV-2 antibody titers between the two age groups. Results Out of 419 participants who met the inclusion criteria, 159 had blood specimens drawn for measurement of SARS-CoV-2 antibody titers. Before the widespread administration of the vaccine, the incidence of COVID-19 in was 4.9% in adolescents vs. 10.2% in adults (P=0.036). After widespread vaccination, the incidence of COVID-19 remained lower in adolescents than in adults (2.2% vs. 8.8%, respectively; P=0.005). The median SARS-CoV-2 antibody titer post-COVID-19 vaccination was 97.85 (range 46.46-98.23) U/mL in adults vs. 96.78 (range 22.08-98.23) U/mL in adolescents (P<0.05). Conclusion While the incidence of COVID-19 was significantly lower in vaccinated adolescents than in vaccinated adults, titers of SARS-CoV-2 IgG neutralizing antibody in adolescents were significantly lower compared to that of adults.
