Effect of Egg and Milk Supplement on Breast Milk Volume at 48 and 72 Hours Postpartum: A Randomized-Controlled Trial

Objective:To determine whether egg and milk supplement with regular diet can increase breast milk volume at 48 and 72 hours postpartum.Materials and Methods: A randomized-controlled trial was conducted at Chiangrai Prachanukroh Hospital between January 2013 and December 2013. One hundred and twenty term pregnant women with spontaneous vaginal delivery were randomized into four groups to receive (1) regular postpartum diet, (2) regular diet with milk supplement, (3) regular diet with egg supplement, or (4) regular diet with egg and milk supplement three meals a day. Breast milk volume was measured using an electric breast pump for 15 minutes for each breast at 48 and 72 hours postpartum. The differences in breast milk volume at 48 and 72 hours postpartum between groups were assessed using an analysis of covariance adjusted for the variables significantly different between groups at the time of delivery. Results:Age of postpartum mothers (p=0.039) and experience of breastfeeding (p=0.045) were significantly different between groups, but not body mass index, gestational age at delivery and infant birth weight. In the analysis of covariance adjusted for maternal age and breastfeeding experience, postpartum mothers who received a regular diet with egg and milk supplement had a significantly higher volume of breast milk at 48 and 72 hours compared to mothers who received a regular diet (p<0.001).Conclusion: A diet with both egg and milk supplement three meals a day significantly increased breast milk volume in lactating women

No increase in cervicovaginal proinflammatory cytokines after Carraguard use in a placebo-controlled randomized clinical trial

Background: Assessment of cervicovaginal cytokine levels may be helpful to evaluate subclinical epithelial inflammation during safety evaluations of candidate microbicides. Methods: Fifty-five HIV-seronegative Thai women were enrolled in a safety trial of the candidate microbicide Carraguard and were randomized to use Carraguard or placebo gel before vaginal sex. Cervicovaginal lavages were collected at baseline and after 1 month of gel use; levels of interleukin (IL)-1β, IL-6, IL-8, and secretory leukocyte protease inhibitor (SLPI) were measured using microwell plate-based enzyme immunoassays. Median levels were compared between the baseline and 1-month follow-up visits using paired t tests; the median change between groups was compared using Wilcoxon rank sum tests. Women were examined for the presence of genital findings; the association between genital findings and cytokine levels was studied. Results: No increase in levels of proinflammatory cytokines after use of Carraguard gel or placebo gel was observed during the study. The median change from the baseline to 1 month of follow-up was not significantly different between Carraguard and placebo groups (IL-1β: -0.3 pg/mL vs. -3.93 pg/mL; P = 0.4, IL-6: -0.3 pg/mL vs. 0 pg/mL; P = 0.3, IL-8: -40.1 pg/mL vs. -53.2 pg/mL; P = 0.8, and SLPI: -26.5 pg/mL vs. 12.6 pg/mL; P = 0.07). Genital findings with intact epithelium were found in 16 (29%) women; these women tended to have somewhat higher IL-6 levels than those with normal epithelium (14.9 pg/mL vs. 8.8 pg/mL; P = 0.08). Conclusion: We found no increase in proinflammatory cytokines after Carraguard and placebo gel use, suggesting that neither gel causes inflammation. Further studies to assess the role of cytokines in microbicide safety studies are warranted

Acceptability of Carraguard vaginal gel use among Thai couples

Objectives: To evaluate the acceptability of candidate microbicide Carraguard among couples participating in a safety trial. Study Design: A 6-month randomized, placebo-controlled trial was conducted in sexually active, low-risk couples in Thailand. Methods: Couples who were monogamous, HIV uninfected, and not regular condom users were enrolled. Acceptability data were collected through structured questionnaires at repeated intervals. At the closing study visit, participants were asked questions about hypothetical product characteristics and future use. Compliance with gel use was assessed by questionnaires, coital diaries, and tracking of used and unused applicators. Results: Among 55 enrolled couples, follow up and adherence with gel use were high and sustained, with 80% of women using gel in over 95% of vaginal sex acts. Because acceptability results from Carraguard and placebo arms were similar, they were combined for this analysis. Overall, 92% of women and 83% of men liked the gel somewhat or very much; 66% of women and 72% of men reported increased sexual pleasure with gel use; and 55% of women and 62% of men reported increased frequency of intercourse. Only 15% of women but 43% of men thought that gel could be used without the man knowing. Although men and women had similar views overall, concordance within couples was low, with no kappa coefficients above 0.31. Conclusion: Carraguard gel use was acceptable to low-risk couples in northern Thailand. Reported associations between gel use and increased sexual pleasure and frequency suggest a potential to market microbicide products for both disease prevention and enhancement of pleasure

Zika Virus Immunoglobulin G Seroprevalence among Young Adults Living with HIV or without HIV in Thailand from 1997 to 2017

Zika virus (ZIKV) epidemiological data in Thailand are limited. We assessed ZIKV IgG seroprevalence among young adults during 1997–2017 and determined factors associated with ZIKV IgG seropositivity. This retrospective laboratory study included randomly selected subjects aged 18–25 years participating in large clinical studies conducted in Thailand during 1997–2017. Stored plasma samples were analyzed for ZIKV IgG using an ELISA test (Anti-Zika Virus IgG, EUROIMMUN, Lübeck, Germany). Sociodemographic, clinical and laboratory data were used in univariable and multivariable analyses to identify factors associated with ZIKV IgG positivity. Of the 1648 subjects included, 1259 were pregnant women, 844 were living with HIV and 111 were living with HBV. ZIKV IgG seroprevalence was similar among the HIV-infected and -uninfected pregnant women (22.8% vs. 25.8%, p-value = 0.335) and was overall stable among the pregnant women, with a 25.2% prevalence. Factors independently associated with ZIKV IgG positivity included an age of 23–25 years as compared to 18–20 years, an HIV RNA load below 3.88 log10 copies/mL and birth in regions outside northern Thailand. Our study shows that a large proportion of the population in Thailand probably remains susceptible to ZIKV infection, which could be the ground for future outbreaks. Continued surveillance of ZIKV spread in Thailand is needed to inform public health policies

Early Postpartum Pharmacokinetics of Lopinavir Initiated Intrapartum in Thai Women ▿ †

Lopinavir (LPV) exposure is reduced during the third trimester of pregnancy. We report the pharmacokinetics of standard LPV-ritonavir dosing (400/100 mg twice daily) in the immediate and early postpartum period when initiated during labor. In 16 human immunodeficiency virus-infected Thai women, the median (range) LPV area under the concentration-time curve and maximum and minimum concentrations in plasma were 99.7 (66.1 to 180.5) μg·h/ml, 11.2 (8.0 to 17.5) μg/ml, and 4.6 (1.7 to 12.5) μg/ml, respectively, at 41 (12 to 74) h after delivery. All of the women attained adequate LPV levels through 30 days postpartum. No serious adverse events were reported

Hepatitis B prevalence and associated factors in adults presenting for infection screening in northern Thailand

Background and aims: Hepatitis B is a leading cause of morbidity and mortality worldwide. In view of the World Health Organization 2030 targets, effective screening of chronic infection is crucial. We have assessed the prevalence and risk factors of hepatitis B surface antigen in adults presenting for screening. Methods: Free-of-charge and anonymous services for simultaneous hepatitis B, hepatitis C, human immunodeficiency virus and syphilis screening and counseling were provided in four facilities in northern Thailand. Analyses were performed separately in clients born before integration into the 1992 hepatitis B vaccine Thailand's Expanded Program on Immunization and in clients born afterwards. Results: Between October 2015 and August 2020, hepatitis B surface antigen prevalence was 7.2 % (185/2578) in clients born before 1992 (95 % confidence interval [CI] = 6.2%–8.2 %). In the multivariable analysis, characteristics independently associated with a higher risk of infection were being born male (adjusted odds ratio [aOR] = 1.49, 95 % CI = 1.10–2.01) and being part of a hill tribe (aOR = 1.65, 95 % CI = 1.01–2.70). Forty-two percent were unaware of their infection. In clients born in 1992 or afterwards, prevalence was 1.5 % (43/2933) (95 % CI = 1.1%–2.0 %) and characteristics independently associated with a higher risk were being born between 1992 and 1995 (aOR = 1.90, 95 % CI = 1.00–3.61), being born male (aOR = 2.60, 95 % CI = 1.34–5.07), being part of a hill tribe (aOR = 5.09, 95 % CI = 2.52–10.26) and having ever injected drugs (aOR = 4.33, 95 % CI = 1.23–15.24). Conclusions: Risk factor-based screening would miss many chronic hepatitis cases. Screening all adults once in their lifetime may be beneficial until the second generation of immunized infants have reached adult age

HIV genital shedding and safety of Carraguard use by HIV-infected women: A crossover trial in Thailand

Objective: To evaluate the safety, including impact on genital HIV RNA shedding, of Carraguard vaginal gel in HIV-infected women. Design: This is a randomized, controlled, crossover study of Carraguard in HIV-infected women in Thailand. Methods: Each woman (CD4+ cell count 51–500 cells/µl and not on antiretroviral therapy) used each treatment (Carraguard, methylcellulose placebo, and no-product) once daily for 7 days during each 1-month period (3-week wash-out). Women were randomized to one of the six possible treatment sequences. Safety assessments were conducted at baseline (pregel), 15 min postgel, day 7, and day 14, and included HIV RNA measurements in cervicovaginal lavage (CVL) specimens. Results: Sixty women were enrolled, and 99% of scheduled study visits were completed. At baseline, median age (34 years), CD4+ lymphocyte count (296 cells/µl), plasma HIV viral load (4.6 log_10 copies/ml), CVL HIV viral load (3.1 log_10 total copies per CVL), and sexual behaviors were similar among randomization groups. HIV viral load, leukocyte and hemoglobin levels, and epithelial cell counts in CVLs were lower 15 min after application of Carraguard or placebo compared with no product; CVL HIV viral load was still lower at day 7 but returned to baseline by day 14. Carraguard use was not associated with prevalent or incident genital findings or abnormal vaginal flora. Conclusion: Carraguard appears to be well tolerated for once-daily vaginal use by HIV-infected women. The observed reduction in CVL HIV viral load in the gel months may be clinically relevant but could have resulted from interference with sample collection by study gels

Increased Burden of Concordant and Sequential Anogenital Human Papillomavirus Infections Among Asian Young Adult Women With Perinatally Acquired HIV Compared With HIV-Negative Peers

BACKGROUND: Youth with perinatally acquired HIV (YPHIV) are at higher risk for anogenital human papillomavirus (HPV) infection. METHODS: We enrolled a cohort of YPHIV and HIV-negative youth in Thailand and Vietnam, matched by age and lifetime sex partners, and followed them up for 144 weeks (to 2017). Participants had annual pelvic examinations with samples taken for HPV genotyping. Concordant infection was simultaneous HPV detection in multiple anogenital compartments (cervical, vaginal, anal); sequential infection was when the same type was found in successive compartments (cervicovaginal to/from anal). Generalized estimating equations were used to assess factors associated with concordant infection, and Cox regression was used to assess factors associated with sequential infection. RESULTS: A total of 93 YPHIV and 99 HIV-negative women were enrolled, with a median age of 19 years (interquartile range, 18-20 years). High-risk anogenital HPV infection was ever detected in 76 (82%) YPHIV and 66 (67%) HIV-negative youth during follow-up. Concordant anogenital high-risk HPV infection was found in 62 (66%) YPHIV versus 44 (34%) HIV-negative youth. Sequential cervicovaginal to anal high-risk HPV infection occurred in 20 YPHIV versus 5 HIV-negative youth, with an incidence rate of 9.76 (6.30-15.13) versus 2.24 (0.93-5.38) per 100 person-years. Anal to cervicovaginal infection occurred in 4 YPHIV versus 0 HIV-negative women, with an incidence rate of 1.78 (0.67-4.75) per 100 person-years. Perinatally acquired HIV was the one factor independently associated with both concordant and sequential high-risk HPV infection. CONCLUSIONS: Children and adolescents with perinatally acquired HIV should be prioritized for HPV vaccination, and cervical cancer screening should be part of routine HIV care for sexually active YPHIV
