Impact of Nutritional Status on the Severity of Dengue Infection Among Pediatric Patients in Southern Thailand.

ABSTRACT: BACKGROUND:Given the lack of specific antiviral drugs and effective vaccine for dengue infection, factors such as host nutritional status that may alter disease progression require investigation. This study examined the relationship between baseline nutritional status and severity of dengue infection in pediatric patients. METHODS:Data from dengue patients aged 1 to 14 years treated at four hospitals in southern Thailand (2017-2018) were reviewed. Dengue infection was classified as dengue fever, dengue hemorrhagic fever and dengue shock syndrome. Children's nutritional status was assessed based on international and national growth charts. Binary logistic regression was used to identify factors associated with dengue severity and malnutrition. RESULTS:Overall, 248, 281 and 43 patients had dengue fever, dengue hemorrhagic fever and dengue shock syndrome, respectively. Overweight was associated with increased risk of dengue severity [odds ratio (OR) = 1.76, 95% confidence interval (CI): 1.13-2.75, P = 0.012; OR = 1.84, 95% CI: 1.09-3.09, P = 0.022, per international and national growth criteria, respectively). Stunting was associated with decreased risk of dengue severity (OR = 0.54, 95% CI: 0.33-0.88, P = 0.013; OR = 0.61, 95% CI: 0.39-0.95, P = 0.030, per international and national growth criteria, respectively). Being overweight was significantly and positively associated with levels of hemoglobin >14 g/dL, hematocrit >42%, hemoconcentration ?20% and platelet count ?50,000/mm, whereas being stunted was significantly and negatively associated with levels of hemoglobin >14 g/dL and hematocrit >42%. CONCLUSIONS:These findings support a hypothesis that malnutrition might influence the severity of dengue infection through host immune response. Overweight children with dengue infections should be closely observed for early signs of severe dengue infection.

Project description:BackgroundToxoplasmosis, being one of the TORCH's infections in pregnant women, is caused by Toxoplasma gondii, an obligate intracellular protozoan parasite. This parasitic infection in pregnancy congenitally causes severe outcomes to their fetus and newborn. This study aimed to determine the seroprevalence and stages of Toxoplasma infection in pregnant women and its associated risks exposures.MethodsThe study was conducted within the pregnant women attending the antenatal clinic (ANC) at Songklanagarind hospital, Hat Yai, Songkhla province, Thailand. The sera of a total of 760 consecutive pregnant women were screened using standard commercial ELISA kits for detection of anti-Toxoplasma IgG and IgM antibodies. IgG avidity in the seropositive for both anti-Toxoplasma IgG and IgM antibodies were also assessed. The pregnant women's socio-demographic, obstetrics and risk factors associated with Toxoplasma seropositivity data were analyzed using univariate and multivariate analyses.ResultsFrom the total 760 pregnant women, 190 (25%, 95% CI = 22.05-28.20) were positive for anti-Toxoplasma antibodies. Of these, 167 (22.0%, 95% CI = 19.0-25.0) were positive for only anti-Toxoplasma IgG antibody and 23 (3.0%, 95% CI = 2.0-4.0) were positive for both anti-Toxoplasma IgG and IgM antibodies. All these samples were high avidity, indicated the infection occured prior to four to five months. By applying statistical univariate analysis, age group, occupation and sources of drinking water showed a significant association with Toxoplasma seropositivity (p < 0.05). Multivariate logistic regression analysis further indicated that the significant factors associated with Toxoplasma seropositivity are age ?26 (OR = 1.65, 95% CI = 1.11-2.44), working as laborer (OR = 1.57, 95% CI = 1.13-2.18) and drinking unclean (piped/tap/rain) water (OR = 1.75, 95% CI = 1.08-2.84).ConclusionThe pregnant women in the active age group, working as laborers and exposure to unclean drinking water from various sources were at higher risk of Toxoplasma infection. Therefore, health education and the awareness of risk exposures regarding this parasitic disease are required to minimize the effects of this parasitic infection in pregnant women as well as in the general population.

Project description:To develop more effective intervention strategies against dengue, it is necessary to identify determinants of knowledge, attitudes, and practices (KAP), which may be influenced by the dengue experiences of the population at risk. The aim of this study was to assess and compare KAP regarding dengue prevention between Thai primary school children with and without experiences of dengue. A cross-sectional study was conducted among children between ages 8 and 13, attending the 50 public primary schools in Kanchanadit district, between October and November 2019. A 32-item questionnaire was used to collect children's socio-demographic characteristics (4 items), health information (2 items), knowledge (10 items), attitudes (7 items), and practices (9 items) towards dengue prevention, which required 30 min to complete. The KAP between groups was then statistically compared, to identify possible causes of observed differences. Of 1979 children, 15.6% self-reported that they had been infected with dengue, while 84.4% had no history of the disease. Most children indicated that they obtained dengue-related information from primary school teachers (73.6%) and their parents (68.5%). No statistically significant differences in mean KAP scores were observed between children with and without dengue experiences (P > 0.05). When KAP scores were categorized as good or poor levels, based on an 80% cut-off, 12.3% of all children had good dengue-related knowledge, 41.6% had good attitudes, and 25.9% reported good preventive practices. Dengue experience was significantly and positively associated with exercising good preventive practices (odds ratio [OR] = 1.34, 95% confidence interval [CI]: 1.03-1.75, P = 0.031). There were significant positive correlations between attitudes and practices in both children with and without dengue experiences (P < 0.001). To enhance KAP towards dengue prevention, further efforts are needed to increase routine dengue health education programs for primary school students who have and have not experienced dengue, and to improve health education programs within communities, especially to assist guardians with the dissemination of dengue literature.
