Concomitant Infection of Helicobacter pylori and Intestinal Parasites: Burden, Sociodemographic and Clinical Characteristics in Hospitalized Children and Adolescents in Northern Lebanon

Background Helicobacter pylori and intestinal parasites are well-known for their high prevalence in children, especially in developing countries. However, their concomitant infections are poorly documented. In this study, we aimed to evaluate the association between intestinal parasites and H. pylori among hospitalized children and adolescents with upper gastrointestinal complaints in Northern Lebanon. Methods A cross-sectional study was conducted involving 297 hospitalized pediatric patients, aged between 1 and 15 years, who presented with gastrointestinal symptoms. The socio-demographic, lifestyle, and gastrointestinal characteristics of all participants were analyzed. Fresh stool samples were collected and screened for the presence of intestinal parasites and H. pylori infections. Results 6.4% of the patients were positive for intestinal parasitic infections, 5.4% were positive for H. pylori infection, and 11.8% were co-infected. The results of the Chi-square test showed that H. pylori infection is significantly associated with parasitic infection but not with a particular species. The most frequent coinfection was H. pylori-Entamoeba histolytica (77.1%). Moreover, H. pylori infection was associated with overcrowding and infrequent washing of vegetables before eating. The prevalence of co-infections increased in patients of mothers with a primary educational level or less. In regards to clinical characteristics, our findings showed a statistically significant relationship between i) gastric reflux and H. pylori, and ii) severe diarrhea and parasitic infection. Conclusion Our data highlighted the association between H. pylori and intestinal parasitic infections. Thus, H. pylori detection could be taken into consideration while screening for parasitic infections in children and adolescents.

Pattern of intestinal parasitic infections in children with malnutrition in Somalia

ObjectivesChildren living in conflict zones plagued with adverse climatic conditions often suffer from acute malnutrition. Being coinfected with intestinal parasites could worsen the prognosis if adequate interventions are not promptly instituted. We determined the pattern of intestinal parasitic infections (IPIs) in children with acute malnutrition in the Bay and Banadir regions of Somalia. MethodsA hospital-based cross-sectional study was conducted from August to October 2023 in 222 children with acute malnutrition aged 6-59 months, using a structured questionnaire and stool examination by a trained laboratorian. The prevalence of IPI was estimated and the pattern of IPI was explored. The relationship between the presence of IPI and demographic characteristics was examined with multiple logistic regression at a 95% level of confidence. ResultsThe mean age was 20.4 ± 12.3 months, 125 (56.3%) were females, and 41.9% were internally displaced. The prevalence of IPI was 82.9% (95% confidence interval: 77.4-87.3), Of the infected, 73.9% (136 of 184) had single parasitic infection and 23.4% (43 of 184) had double parasitic infections. Ascaris lumbricoides (46.6%), Giardia lamblia (22.1%), and Entamoeba histolytica (17.6%) were the most common parasites identified. The age of 13-36 months (adjusted odds ratio: 1.13, P = 0.02) and eating once a day (adjusted odds ratio: 1.13, P = 0.06) were associated with being infected with intestinal parasites. ConclusionsThe prevalence of intestinal parasitic infection was high in children with malnutrition in the Bay and Banadir regions. Deworming should be extended to all children with malnutrition. Food, sanitation, and water provision initiatives should be improved at the community level.

Intestinal parasitic infections in children from marginalised Roma communities: prevalence and risk factors

BackgroundIntestinal parasitic infections remain a significant global health issue, particularly affecting poor and marginalised populations. These infections significantly contribute to children’s diseases, malnutrition, poor school performance, cognitive disorders, and future economic losses. This study aimed to explore and compare the occurrence of intestinal parasites in early childhood among the group of infants from the Slovak majority population and from marginalised Roma communities (MRCs). Furthermore, it aimed to explore the health complaints of children with and without intestinal parasitic infection in the past month and assess the effect of various risk factors on the occurrence of intestinal parasitic infection in infants from MRCs.MethodsWe obtained cross-sectional data from mothers and stool samples of their children aged 13–21 months using the first wave of the longitudinal RomaREACH study. A total of 181 stools from infants were analysed: 105 infants from the Slovak majority population and 76 from MRCs.ResultsInfants from MRCs are significantly more often infected by Ascaris lumbricoides, Trichuris trichiura and Giardia duodenalis than their better-off peers from the majority population. Infection rates are 30% in infants from MRCs vs. 0% in the majority population (p < 0.001). Single and mixed infections were observed in children from MRCs. Infants with intestinal parasitic infections suffer significantly more often from various health complaints, particularly cough, stomach ache, irritability, and diarrhoea. Within MRCs, the risk of parasitic infections in infants is significantly increased by risk factors such as the absence of flushing toilets in households (OR = 4.17, p < 0.05) and contact with un-dewormed animals (OR = 3.61, p < 0.05). Together with the absence of running water in the household, these three factors combined increase the risk more than ten times (p < 0.01).ConclusionMaintaining hygienic standards in conditions of socioeconomic deprivation in MRCs without running water and sewage in the presence of un-dewormed animals is problematic. These living conditions contribute to the higher prevalence of parasitic infections in children from MRCs, causing various health complaints and thus threatening their health and healthy development.

Intestinal Parasitic Infection in Children and Adolescents With Ocular Diseases: The Prevalence, Spectrum, and Effect of Lockdown During the COVID-19 Pandemic.

People with visual impairments and blindness face challenges in performing regular tasks such as maintaining proper sanitation, which makes them vulnerable to intestinal parasitic infections. This study aims to examine the prevalence and distribution of intestinal parasitic infections in children and adolescents with ocular diseases and to assess if the lockdown during the COVID-19 pandemic affected these rates. This retrospective, hospital record-based study was conducted among children and adolescents attending the Regional Institute of Ophthalmology in Kolkata, India. It involved routine stool examinations as part of their treatment during 2019-2020. Early morning stool specimens were collected and brought to the institute laboratory in containers. Stools were examined under a microscope for cysts, ova, parasites, and adult worms. Findings were recorded in the laboratory record book. These data were then extracted into a spreadsheet and analyzed using IBM SPSS Statistics for Windows, Version 26 (Released 2019; IBM Corp., Armonk, New York). The prevalence of intestinal parasitic infections was 8.59% (59 out of 687 patients). Among those 59 positive cases, Ascaris lumbricoides, Giardia lamblia, Entamoeba histolytica, Trichuris trichiura, Taenia spp., Enterobius vermicularis, and Isospora belli were detected in 27 (45.8%), 15 (25.4%), 8 (13.6%), 6 (10.2%), 3 (5.1%), 2 (3.4%), and 1 (1.7%) patients, respectively. The positivity rate of stool samples was higher from September and thereafter from January to March. The sample positivity rate was higher post-pandemic and lockdown, but not statistically significant (11.5% vs. 5.3%; χ²=4.044, df=1, p=0.44). Ascaris lumbricoides was the most commonly observed intestinal parasite in children and adolescents with ocular disease in our setting. Seasonal variation was noted with higher case positivity at the end of the rainy season and thereafter in winter. Therefore, we propose to strengthen the routine deworming program during this period in Eastern India. Higher sample positivity after the pandemic may be attributed to school closures during the lockdown period, which might have caused some children to miss their routine deworming medication.

Prevalence and Determinants of Intestinal Parasitic Infections in Children from Four Cities in Kyrgyz Republic

Prevalence and Determinants of Intestinal Parasitic Infections in Children from Four Cities in Kyrgyz Republic

Intestinal Parasitic Infections and Associated Factors Among Primary School Students in Tehran

Background: Parasitic infections in children can negatively impact their growth, health, nutrition status, and cognitive development. Objectives: This study aimed to investigate intestinal parasitic infection and its relationship with the nutritional status of primary school students in Tehran in 2020. Methods: The current study was conducted on 250 samples collected by the available sampling method from 2 selected residential settlements in Tehran. The samples were tested using both direct and formalin ether concentration (sedimentation) methods. The nutritional status of participants was evaluated using the Mini Nutritional Assessment (MNA) questionnaire. The data were analyzed by the χ2 test. A significant level was considered 0.05. Results: Of the 250 student samples surveyed, 45 exhibited parasitic infection. In terms of nutrition, 18 cases were malnourished, 212 cases were exposed to malnutrition, and 20 cases had normal nutrition. The frequency of parasitic infection was higher in malnourished students (P &lt; 0.05). It was also higher in students whose parents' education levels (especially the mother) were lower. Conclusions: It seems that parasitic infections are associated with students’ nutritional status and their parent education.

Global prevalence of enterobiasis in young children over the past 20 years: a systematic review and meta-analysis.

Parasitic infections are the most common diseases worldwide, and enterobiasis is a common parasitic infection in children. Various studies have reported on the prevalence of Enterobius vermicularis in different regions of the world. However, no study has gathered and analyzed this data systematically. Our systematic review and meta-analysis investigated the overall prevalence of E. vermicularis among children globally. Data were extracted from 4 available databases for studies published from January 2002 to April 2022. The quality of the included studies was scored based on the standard Strengthening the Reporting of Observational Studies in Epidemiology. A random-effect model was chosen to calculate the pooled prevalence and corresponding 95% confidence interval (CI) according to the degree of heterogeneity in the included studies. Thus, 40 publications (42 data sets) that included 3,279 children with enterobiasis met all criteria and were included in the analysis. The meta-analysis showed that heterogeneity among the included studies was high (Q=4,399.35, I2=99.96%; df=41; p<0.001). The pooled global prevalence of enterobiasis among the studied children was 12.9% (95% CI, 8.2%-17.7%). Our systematic review and meta-analysis estimated that, for the past 20 years, 12.9% of children around the world have been infected with E. vermicularis.

Prevalence of Intestinal Parasitic Infections, Genotypes, and Drug Susceptibility of Giardia lamblia among Preschool and School-Aged Children: A Cross-Sectional Study in Thailand.

This study aimed to estimate the prevalence of intestinal parasitic infections in children and assess the drug susceptibility and genotypes/assemblages of Giardia lamblia in Thailand. This cross-sectional study was conducted among children aged 3-12 years in Sangkhlaburi District, Kanchanaburi Province, Thailand, between 25 September 2017 and 12 January 2018. Parasites were identified by stool microscopic examination, cultivation of intestinal parasitic protozoa, and enzyme-linked immunosorbent assay (ELISA). Drug susceptibility and genotype of G. lamblia were performed, respectively, by a resazurin assay and Triosephosphate Isomerase A and B genes using modified primers and probes. Among the 661 participants, 445 had an intestinal parasitic infection, resulting in a prevalence of 67.32% (95% CI: 63.60-70.89%). Blastocystis hominis was the most prevalent protozoa infection (49.32%; 95% CI: 45.44-53.22%), while Ascaris lumbricoides was the most prevalent helminth infection (0.91%; 95% CI: 0.33-1.97%). The prevalence of G. lamblia was 17.40%, with genotype B being the most common. According to our study, intestinal parasitic infections were commonly found in Thai children. G. lamblia was the most common pathogenic protozoa infection identified and exhibited less susceptibility to metronidazole compared to furazolidone and mebendazole.

The Pattern of Pediatric Parasitic Skin Diseases in a Secondary Hospital in East Java: A Retrospective Study

Background: Epidermal parasitic skin diseases (EPSDs) are a group of neglected infectious diseases caused by parasites that infect the upper layer of the skin. A parasitic infection of the skin is caused by small insects or worms that burrow into the skin to live there or lay their eggs. EPSDs are a public health issue and can occur in children of all ages. Purpose: This study aims to describe the pattern and incidences of parasitic skin infections in children. Methods: This is a cross-sectional study utilizing medical records from the Dermatology and Venereology Clinic of Dr. Harjono Ponorogo General Public Hospital from 2016 to 2020. Result: Our study showed that, of the 1426 children brought to our clinic, parasitic infection was the second most common skin disease found in children with a prevalence of 27.1%. Parasitic infection in children was dominated by males with a proportion of 69.7%, and occurred mostly in the ≥13-year-old age group. Among all ages, scabies is the most frequent parasitic infection found, followed by cutaneous larva migrant (CLM) and pediculosis. Conclusion: The prevalence of EPSDs is increasing with age and is more common in males. This high prevalence is probably due to increased intensity of contact with other people, decreased parental care, and low socio-economic status.

Clinical profile and severity of Plasmodium vivax and falciparum malaria in hospitalized children from North India.

Malaria is the most common parasitic infection in children and the most common cause of mortality by vector-borne disease in tropical countries. In these endemic countries there is limited published literature on the clinical profile and severity of Plasmodium vivax malaria in children. We highlight the clinical presentations and severity of malaria in children belonging to Uttar Pradesh, North India Methods: This observational study was conducted in a tertiary care hospital, in Moradabad, western Uttar Pradesh, India. Children (aged 6 months-18 years) hospitalized from June 2019 to May 2020 with a clinical picture consistent with malaria along with a positive rapid malaria antigen test (RMAT) and/or positive peripheral blood smear for malaria were enrolled. All data about the clinical profile and laboratory features were recorded. Results were analyzed for significance using appropriate statistical tests for continuous and categorical data. One hundred children were enrolled in this study; 59 cases had Plasmodium vivax (PV) malaria, 33 cases had Plasmodium falciparum (PF) malaria, and 8 cases had mixed infections (both PV and PF). Among 59 children with P V malaria, 44 (74%) had severe malaria and 15 (26%) had uncomplicated malaria. Severe malarial anaemia (43.2%), followed by jaundice (36.4%), impaired renal function (21.6%), significant bleeding (18.9%), shock (18.9%), and prostration (16.2%), were the main severity parameters of malaria among these hospitalised children. Impaired renal function (P-value = 0.01) and unconsciousness (P-value = 0.02) were more frequent in Plasmodium falciparum cases. Other severity parameters were not significant between the vivax and falciparum species. We conclude that a significant proportion of severe malaria was caused by Plasmodium vivax in this region, where both species coexist. Plasmodium vivax malaria is no longer the benign entity it was around ten years ago in hospitalised children. Severe malarial anaemia was the most common severity parameter found in both Plasmodium vivax and P. falciparum species. The clinical presentation and a change in the severity parameters in vivax malaria indicate a recent shift in the disease severity from benign to fatal.

Is pinworm infection still a public health concern among children in resource-rich regions? Trends in pinworm infection prevalence and associated factors among children in Hualien County, Taiwan: a retrospective cross-sectional study

BackgroundEnterobius vermicularis (pinworm) is a common intestinal parasitic infection in children. A gradual decrease in the prevalence of pinworm infection has been noted in resource-rich settings, such as Taiwan. However, the influence of sociodemographic factors on the temporal trend in pinworm infection rates in children under the current pinworm infection prevention policy in Taiwan is not well characterized. This study aimed to evaluate the trend of pinworm infection prevalence and the associated factors among children in Hualien County, Taiwan.MethodologyIn this retrospective cross-sectional study, we included a total of 56,197 students (aged 6–10 years) in grades 1 and 4 in Hualien in 2009–2018. Children were screened for pinworm infection using adhesive cellophane perianal swabs in the routine student health examination. Logistic regression was conducted to evaluate the factors associated with pinworm infection. Associations between dependent and independent variables were measured by odds ratios. The Cochran–Armitage test was used to assess whether there were significant trends in different stratifications. Variables with P-values < 0.05 were considered statistically significant.ResultsA total of 56,197 school-age children from grades 1 and 4 during 2009–2018 were included. Young age and male sex were risk factors for pinworm infection (P < 0.001). A negative correlation between body mass index and enterobiasis was observed, and decreased pinworm infection was noted during the study reference period. Children living in suburban and rural areas had higher odds of having a pinworm infection than those living in urban areas (P < 0.001). A significant decrease in the overall prevalence rate of pinworm infection was observed among children in 2009–2018 (P < 0.001). However, there was no obvious change in the pinworm infection rate in rural areas during this period (P = 0.953), and it was higher than that in urban and suburban areas.ConclusionsThe overall prevalence of pinworm infection gradually decreased from 2009 to 2018 among school-age children in Hualien. However, there was no declining trend in pinworm infection in rural areas. Young age, male sex, and rural residence were significantly associated with pinworm infection. Pinworm infection remains a major public health concern among children in rural areas of Hualien.

Parasitic infections as potential risk factors for attention deficit hyperactivity disorder (ADHD) in children.

Attention deficit hyperactivity disorder (ADHD) represents a mysterious neuropsychiatric alarming concern due to indefinite etiopathogenesis among children. Notably, the studies which investigated the correlation between ADHD and parasitic infections are insufficient. Therefore, this research aimed to assess the correlation between ADHD and some tissue dwelling and intestinal parasitic infections in children. The study was conducted on 200 children, including 100 children suffering from ADHD (Group I) and 100 healthy children as a control group (Group II). All caregivers fulfilled predesigned sociodemographic form and Conners parent rating scale (CPRS-48) questionnaire. Blood samples were collected to determine hemoglobin level as well as relative eosinophilic count. The presence of anti-Toxoplasma IgG and anti-Toxocara IgG in serum by Enzyme-Linked Immunosorbent Assay (ELISA) was further investigated. Also, micronutrients as zinc, iron, and copper levels were measured. Schistosoma antigen was investigated in urine samples. Stool samples were subjected to direct wet smear, concentration technique and modified Ziehl-Neelsen (MZN) staining for coccidian parasites detection. Cryptosporidium parvum, Giardia lamblia and Entamoeba histolytica antigens were investigated in stool samples. Group I expressed more liability to sociodemographic risk factors, decreased levels of Hb, iron, zinc, and copper with statistically significant difference (P < 0.001). Comparison between Group I and Group II regarding the detected parasitic infections exhibited statistically significant difference except Schistosoma antigen positivity which expressed no statistical significance. The present study concluded that the parasitic infections with their consequences are potential risk factors in children with ADHD indicating that their early diagnosis and treatment may help in ADHD prevention.

Incidence of Soil Transmitted Helminth (STH) Infection in School-Age Children in the Archipelago of North Sulawesi

Archipelagic areas are areas that are still lacking in the application of good sanitation life. One of the infectious diseases related to sanitation is worm infection. This study aims to identify the presence or absence of Soil Transmitted Helminth (STH) intestinal parasitic infection in children in the archipelago. This research was carried out at the Bethel Alo Christian Education Foundation Elementary School, Talaud Regency. This research is a descriptive research. The sampling technique is Porposive sampling, the sample of this research is 35 samples. After microscopic examination using faecal samples, it was found that 5 samples were positive for helminthiasis while 30 other samples were negative. Of the 5 samples, 2 positive samples of Ascaris lumbricoides worm eggs, 2 samples of Trichuris trichiura, and 1 sample of mixed infection of Ascaris lumbricoides and Trichuris trichiura. The results showed as many as 5 positive samples or 14.29% of the 35 samples consisting of 2 samples or 5.71% of Ascaris lumbricoides, 5.71% of Trichuris trichiura, and 1 sample of Mix infection or 2.85%.

A bibliometric analysis of research productivity on parasitic infections in children during the 15-year period / Uma análise bibliométrica da produtividade da investigação sobre infecções parasitárias em crianças durante o período de 15 anos

Parasitic infections in children (PIC) represent an important public health issue regarding that children are more vulnerable to these infections and its consequences. Many countries have neglected PIC in their health agendas and budgets, which has hindered scientific production about it. In this sense, bibliometric analyzes have been useful to identify the panorama of scientific production for many diseases and thus assist in decision-making. Thus, this review aims to analyze the brazilian and worldwide scientific production of PIC between 2006 and 2020. The terms “Parasitic diseases” and “Children” were used for search in Scopus database. The variables were organized and simple linear regression was applied using Graphpad Prism 7. Values of p&lt;0.05 were considered statistically significant. was USA (18.5%), UK (8.9%) and Brazil (7.8%) were the countries that performed more scientific research on IPC. Among Brazil´s federal unities, São Paulo (34.3%), Rio de Janeiro (32%) and Minas Gerais (17.3%) published more scientific papers on PIC. The Brazilian research were mostly performed by public institutions, especially FIOCRUZ, USP and UFMG which published 19%, 16% and 10.6% of total Brazilian scientific production about PIC, respectively. There was a significant increase in scientific production about PIC over the 15 years analyzed, especially about schistosomiasis, giardiasis and trichuriasis. In addition, scientific journals from developed countries such as London School of Hygiene &amp; Tropical Medicine and Plos Neglected Tropical Diseases were the main publishers of papers about PIC. Scientific production on PIC increased between 2006 and 2020 with participation of developed countries (USA and UK) and developing countries (Brazil). This increase in scientific production seems to be driven by the increase in studies on giardiasis, trichuriasis and especially schistosomiasis.

Neglected Diseases-Parasitic Infections among Slovakian Children from Different Populations and Genotypes of Giardia duodenalis.

Children are most prone to parasitic infections. The objectives of the study were to examine the occurrence of parasitic infections in children from different populations and to perform molecular characterization of human Giardia duodenalis isolates. We examined 631 stool samples from Roma and non-Roma children for the presence of parasitic developmental stages. Samples were collected from three eastern Slovakia districts. The ages of the children ranged from 1 months to 17 years. Subsequently, the molecular characterization of human G. duodenalis isolates by PCR detected triosephosphate isomerase (tpi) and beta-giardin (bg) genes was performed. The overall prevalence of parasitic infection was 19.8%. Ascaris lumbricoides eggs were the most frequent, with an occurrence of about 13.8%. G. duodenalis cysts were present in 6.3% of samples. G. duodenalis isolates obtained from 13 children were subjected to DNA sequencing with tpi and bg genes. Five isolates were categorized as bearing subassemblage BIII, the three isolates as subassemblage BIV, one person was infected with a mixture of subassemblages BIII and BIV, four children had subassemblage AII, and one isolate revealed a structure corresponding with subassemblage AI. Our work is proof that poverty and poor hygiene contribute the most to public health problems associated with neglected parasitic diseases.

The Impact of Maternal Depression and Parent\u2013Child Interactions on Risk of Parasitic Infections in Early Childhood: A Prospective Cohort in Benin

ObjectivesMaternal depression occurs in 13–20% of women from low-income countries, which is associated with negative child health outcomes, including diarrheal disease. However, few studies have investigated its impact on child risk of infectious disease. We studied the impacts of maternal depressive symptoms and parent–child interactions, independently, on the risk of Plasmodium falciparum malaria and soil-transmitted helminth infection in Beninese children.MethodsOur population included mothers and children enrolled in a clinical trial during pregnancy (MiPPAD) in Benin. The Edinburgh Postnatal Depression Scale (EPDS) assessed maternal depressive symptoms and the home observation measurement of the environment (HOME) assessed parent–child interactions. Blood and stool sample analyses diagnosed child malaria and helminth infection at 12, 18, and 24 months. Negative binomial and Poisson regression models with robust variance tested associations.ResultsOf the 302 mother–child pairs, 39 (12.9%) mothers had depressive symptoms. Median number of malaria episodes per child was 3 (0–14) and 29.1% children had at least one helminth infection. Higher EPDS scores were associated with lower HOME scores; relative risk (RR) 0.97 (95% confidence interval (CI) 0.95, 0.99), particularly with lower acceptance, involvement, and variety subscales; RR 0.92 (95% CI 0.85, 0.99), RR 0.82 (95% CI 0.77, 0.88), RR 0.93 (95% CI 0.88, 0.99), respectively. However, neither exposure was associated with risk of parasitic infection in children.Conclusions for PracticeMaternal depressive symptoms are associated with poor parent–child interactions, particularly acceptance of behavior, involvement with children, and variety of interactions, but these exposures do not independently impact risk of parasitic infection in children.

PREVALENCE OF PARASITIC INFECTIONS IN CHILDREN OF BOKE, GUINEA.

Helminthic and intestinal protozoan infections and malaria infections are common in children less than 15 yr old in sub-Saharan Africa, but little is known about these infections in Guinea. The aim of this study was to determine the prevalence of parasitic infections in children aged less than 15 yr and the relationship of these infections with anemia. The cross-sectional study was done in Dabbis sub-prefecture in the Boke region of Guinea from 18 to 26 March 2017. A simple random sampling at the household level was performed, and 1 child under the age of 15 was included per eligible household. A total of 392 children were included in the analysis. Clinical and parasitological information were assessed, including anthropometric measures (weight and height), disease symptoms, hemoglobin level, and malaria parasitemia. Helminthic and protozoan intestinal infections were present in 59.7% of the children surveyed. Malaria infection prevalence was 45.5% when assessed by microscopy and 43.6% when assessed by a rapid diagnostic test. Plasmodium falciparum, accounting for 84.2% of malaria infections, was the main malaria species infection. Gastrointestinal parasites were present in 19.1% of children. The main gastrointestinal parasites present included Entamoeba coli (5.4%) and Giardia intestinalis (5.1%). There was no association between the presence of anemia and the parasitic status of the children. Parasitic screening and mass treatment in this age group, as well as household awareness raising, would reduce cases of parasitic infections in rural Guinea.

Geographic differences in the distribution of parasitic infections in children of Bolivia

BackgroundA high percentage of the population in Latin America lives with intestinal parasitic infections, a neglected tropical disease frequently not treated. Intestinal parasitism is associated with other disorders, but information about the epidemiological situation in countries like Bolivia is scarce. Environmental conditions play a role in the prevalence of certain parasites. The main objective was to know the current situation of parasitic infections among children under 12 years old from different geographical areas of Cochabamba – Bolivia. MethodsWe analysed the laboratory reports of four second-line hospitals in different areas and the Tertiary Care Hospital. Results of stool examinations performed between 2011 and 2015 in children under 12 years of age were collected. ResultsWe gathered the results of 23,221 examinations. The 89% of children were less than five years old. Pathogenic parasites were found in 31%. Entamoeba histolytica and Giardia lamblia were the two most prevalent parasites in all areas. Helminths were 19% of positive samples and Ascaris lumbricoides was the most prevalent. Parasitic infections are more frequent in tropical areas where helminths are highly concentrated. Pre-school age children (OR: 5.296; 95% CI: 4.81–5.83) and semi-tropical area (OR: 3.26; 95% CI: 2.90–3.66) were strongly associated to the presence of pathogenic parasites. ConclusionsParasitic infections in children are still very prevalent in Bolivia. Protozoan infections are a major problem, while the prevalence of helminths seems to be decreasing. The most vulnerable population is still concentrated in semi-tropical and tropical areas, where the risk of parasitic infection is probably increased due to poor environmental conditions. Our results could allow reconsideration of more effective parasitic disease control policies, taking into account regional characteristics.
