Schistosoma mansoni infection as a predictor of severe anaemia in schoolchildren in eastern Sudan

AbstractA cross-sectional study was carried out to investigate the prevalence and risk factors for severe anaemia among schoolchildren in New Halfa, eastern Sudan. After taking age and gender, haemoglobin (Hb) levels were measured and all children were screened for malaria and intestinal parasitic infections, including schistosomiasis. Six hundred and forty (230 boys, 410 girls) schoolchildren aged 8–18 years were enrolled. The mean (SD) of the haemoglobin was 9.6 (1.7) mg/dl. One hundred and eleven (17.3%) and 33 (5.2%) children had Schistosoma mansoni infection and Hymenolepis nana infection, respectively. Five hundred and eighty (90.6%) of these children had anaemia (Hb < 12 g/dl), and 103 (16.0%) of them had severe anaemia (Hb < 8 g/dl). Girls (OR = 2.5, 95% CI = 1.1–5.3; P = 0.01) were at higher risk for severe anaemia in univariate and multivariate analyses. Schistosoma mansoni infections were associated with severe anaemia in univariate analyses only. Thus, there was a high prevalence of severe anaemia among these children. This needs to be investigated in more depth in the future, and more attention should be paid to the health of adolescent girls.

Abstract Background This cross-sectional study was carried out in different settlements of Gabon to determine the influence of single or multiple parasite carriage on haemoglobin (Hb) levels. Methods Between April 2015 and June 2016, healthy volunteers from urban, peri-urban and rural areas were screened for malaria, blood filariasis and intestinal parasitic infections using microscopic methods. Hb concentration was measured with a Hemocue analyser. The association between parasite carriage and anaemia was assessed. Results Among the 775 volunteers examined, 319 (41.2%) were from rural villages and 76.0% were adults. Filariasis, intestinal parasitic infections, Plasmodium falciparum and polyparasitism were detected in 15.6, 14.6, 9.5 and 6.8% of participants, respectively. Anaemia prevalence was 72.6%, with rates of mild, moderate and severe anaemia being 30.9, 61.1 and 8.0%, respectively. The median Hb level was lowest in the presence of hookworms (7.1 g/dl [interquartile range {IQR} 6.8–7.5]), Schistosoma intercalatum (6.9 g/dl), Trichuris trichiura (10.1 g/dl [IQR 8.9–11.5]) and Plasmodium falciparum (10.0 g/dl [IQR 9.1–11.2]) compared with filariaemia (12.1 g/dl [IQR 10.5–13.2]) (p=0.03). Moderate to severe anaemia predominated among those single-infected with P. falciparum (69.5%) or co-infected with intestinal parasitic infections and P. falciparum (76.2%), while it was found in only 23.2% of individuals with filariasis. All participants with soil-transmitted helminths and more than half with a Blastocystis sp. (68.8%) infection had moderate anaemia. Conclusions The prevalence of anaemia is high. Asymptomatic parasite carriage is associated with anaemia in this surveyed population in Gabon.

Study Participants

Background Intestinal Parasitic Infections are the most prevalent diseases in the world, predominantly in developing countries. It is estimated that more than two billion people are affected globally, mostly in tropical and sub-tropical parts of the world. Ethiopia is one of the countries in Africa with a high prevalence of intestinal parasites. However, there is a limited study conducted in the study area. Hence, this study was to assess the prevalence and associated factors of intestinal parasitosis among patients attending at Sanja Primary Hospital, Northwest Ethiopia. Methods An institutional-based cross-sectional study was conducted at Sanja Primary Hospital from January 1 to August 20, 2019. Stool samples were collected from 1240 study participants and analyzed by direct wet mount and formal ether concentration techniques. Furthermore, sociodemographic and explanatory variables were collected using a face-to-face interview. Data were entered into Epi data version 4.4.2.1 and transferred to SPSS version 23 for analysis. Bivariate and multivariate binary logistic regression models were fitted to identify associated factors of intestinal parasitic infections. Adjusted Odds Ratio (AOR) with 95% confidence interval (CI) was considered to ascertain the significance of the association. Results The overall prevalence of intestinal parasitic infection was 52.9% (95% CI: 50.2%-55.5%). Entamoeba histolytica/dispar (21.5%) was the leading cause of intestinal parasitosis followed by Hookworm species (13.3%). Furthermore, the rate of double and triple parasitic infections was observed in 6.1% and 0.5% of study participants respectively. Being Illiterate (AOR: 2.87, 95% CI: 1.06–7.47, p = 0.038), swimming habits of more than 4 times a month (AOR = 2.91, 95% CI 1.62–5.24, p< 0.001) and not washing hands before a meal (AOR: 3.92, 95% CI: 1.74–8.83, p = 0.001) were the key factors significantly associated with intestinal parasitic infection. Conclusions The present study showed that the prevalence of intestinal parasitosis is high in the study area. Therefore, there is a need for an integrated control program, including improving personal, environmental sanitation and health education should be given to have a lasting impact on transmission.

Background: Soil-transmitted helminths and protozoan parasitic infections are endemic throughout the world. The problem of intestinal parasitic infection is higher among developing countries where children are the most vulnerable groups. Although health information related to parasitic infections is available globally, it is often limited in rural setups in least developed countries. This study was, therefore, conducted to assess socioeconomic predictors of intestinal parasitic infections among under-five children in rural Dembiya, Northwest Ethiopia. Methods: This cross-sectional study was conducted among 224 randomly selected households with under-five children. We used questionnaire to collect data and direct stool examination to identify intestinal parasitic infections. Adjusted odds ratio (AOR) with 95% confidence interval (CI) and P < .05 was used to identify socioeconomic predictors of parasitic infections. Results: We found that 25.4% (95% CI = [20.2, 31.1]) under-five children had intestinal parasitic infection. Ascaris lumbricoides was the leading infection, which accounted 44 of 224 (19.6%). The prevalence of childhood intestinal parasitic infections was higher among households with no members whose education level is secondary and above (AOR = 3.36, 95% CI = [1.23, 9.17]). Similarly, intestinal parasitic infections were statistically associated with presence of 2 under-five children in a household (AOR = 3.56, 95% CI = [1.29, 9.82]), absence of frequent health supervision (AOR = 3.49, 95% CI = [1.72, 7.09]), larger family size (AOR = 2.30, 95% CI = [1.09, 4.85]), and poor household economic status (AOR = 2.58, 95% CI = [1.23, 5.41]). Conclusions: Significant proportion of children was infected with intestinal parasitic infection in rural Dembiya. Educational status of family members, number of under-five children in a household, health supervision, family size, and wealth index were statistically associated with parasitic infections. Provision of anthelmintic drugs, health supervision, and health education targeted with transmission and prevention of infections are recommended.

Abstract Background Intestinal parasitic infection is one of the parasitic infections affecting people living in prison. Helminths and intestinal protozoan infections are the most common parasitic infection that may cause serious life-threatening diseases in inmates living in developing countries. This study was aimed to investigate the prevalence and associated factors of intestinal parasitic infections (IPIs) among inmates living in Arba Minch prison, southern Ethiopia. Methods Institutional based cross sectional study was conducted on Arba Minch inmates, southern Ethiopian. Pre-tested semi-structured questionnaire was used to gather the data of socio-demographic characteristics, hygiene status of the prisoners, sanitation condition of the prison, and associated factors for IPIs by face to face interview. Direct wet-mount examination and formol-ether sedimentation techniques were used to examine intestinal parasitic infection from stool specimens. Binary logistic regression analysis was used to see the association between different variables and the IPI. Odds ratio with 95% CI was computed to determine the presence association and strength of the associated factors. Result A total of 320 prisoners were participated in this study. Of these, 154(48.1%) of them were infected with one or more intestinal parasites. Eight different intestinal parasites species were identified and Giardia lamblia was the predominant parasite. Among infected inmates, nearly one out of four of them had multiple parasitic infections dominated by Giardia lamblia and E. histolytica/dispar co-infection. Sleeping in group [AOR = 1.9; 95% CI: (1.0–3.8)], married prisoners [AOR = 1.8; 95% CI: (1.1–2.9)], and hand washing habits after handling soil [AOR = 2.4; 95% CI: (1.0–5.6)] were independently associated with IPI. Conclusion High prevalence of intestinal parasitic infection was detected in Arba Minch inmates, southern Ethiopian. Absence of hand washing, marital status, and way of sleeping were the factors associated with the IPI. Implementation of mass drug administration, education on water, sanitation and hygiene (WASH) and periodic screening of intestinal parasitic infection is very important to reduce the high prevalence IPIs in prison.
