Clinical and nutritional correlates of bacterial diarrhoea aetiology in young children: a secondary cross-sectional analysis of the ABCD trial.

OBJECTIVE: The objective was to assess the association between nutritional and clinical characteristics and quantitative PCR (qPCR)-diagnosis of bacterial diarrhoea in a multicentre cohort of children under 2 years of age with moderate to severe diarrhoea (MSD). DESIGN: A secondary cross-sectional analysis of baseline data collected from the AntiBiotics for Children with Diarrhoea trial (NCT03130114). PATIENTS: Children with MSD (defined as >3 loose stools within 24 hours and presenting with at least one of the following: some/severe dehydration, moderate acute malnutrition (MAM) or severe stunting) enrolled in the ABCD trial and collected stool sample. STUDY PERIOD: June 2017-July 2019. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Likely bacterial aetiology of diarrhoea. Secondary outcomes included specific diarrhoea aetiology. RESULTS: A total of 6692 children with MSD had qPCR results available and 28% had likely bacterial diarrhoea aetiology. Compared with children with severe stunting, children with MAM (adjusted OR (aOR) (95% CI) 1.56 (1.18 to 2.08)), some/severe dehydration (aOR (95% CI) 1.66 (1.25 to 2.22)) or both (aOR (95% CI) 2.21 (1.61 to 3.06)), had higher odds of having likely bacterial diarrhoea aetiology. Similar trends were noted for stable toxin-enterotoxigenic Escherichia coli aetiology. Clinical correlates including fever and prolonged duration of diarrhoea were not associated with likely bacterial aetiology; children with more than six stools in the previous 24 hours had higher odds of likely bacterial diarrhoea (aOR (95% CI) 1.20 (1.05 to 1.36)) compared with those with fewer stools. CONCLUSION: The presence of MAM, dehydration or high stool frequency may be helpful in identifying children with MSD who might benefit from antibiotics.

Azithromycin for Bacterial Watery Diarrhea: A Reanalysis of the AntiBiotics for Children With Severe Diarrhea (ABCD) Trial Incorporating Molecular Diagnostics.

BACKGROUND: Bacterial pathogens cause substantial diarrhea morbidity and mortality among children living in endemic settings, yet antimicrobial treatment is only recommended for dysentery or suspected cholera. METHODS: AntiBiotics for Children with severe Diarrhea was a 7-country, placebo-controlled, double-blind efficacy trial of azithromycin in children 2-23 months of age with watery diarrhea accompanied by dehydration or malnutrition. We tested fecal samples for enteric pathogens utilizing quantitative polymerase chain reaction to identify likely and possible bacterial etiologies and employed pathogen-specific cutoffs based on genomic target quantity in previous case-control diarrhea etiology studies to identify likely and possible bacterial etiologies. RESULTS: Among 6692 children, the leading likely etiologies were rotavirus (21.1%), enterotoxigenic Escherichia coli encoding heat-stable toxin (13.3%), Shigella (12.6%), and Cryptosporidium (9.6%). More than one-quarter (1894 [28.3%]) had a likely and 1153 (17.3%) a possible bacterial etiology. Day 3 diarrhea was less common in those randomized to azithromycin versus placebo among children with a likely bacterial etiology (risk difference [RD]likely, -11.6 [95% confidence interval {CI}, -15.6 to -7.6]) and possible bacterial etiology (RDpossible, -8.7 [95% CI, -13.0 to -4.4]) but not in other children (RDunlikely, -0.3% [95% CI, -2.9% to 2.3%]). A similar association was observed for 90-day hospitalization or death (RDlikely, -3.1 [95% CI, -5.3 to -1.0]; RDpossible, -2.3 [95% CI, -4.5 to -.01]; RDunlikely, -0.6 [95% CI, -1.9 to .6]). The magnitude of risk differences was similar among specific likely bacterial etiologies, including Shigella. CONCLUSIONS: Acute watery diarrhea confirmed or presumed to be of bacterial etiology may benefit from azithromycin treatment. CLINICAL TRIALS REGISTRATION: NCT03130114.

Burden of diarrhea and antibiotic use among children in low-resource settings preventable by Shigella vaccination: A simulation study.

BACKGROUND: Shigella is a leading cause of diarrhea and dysentery in children in low-resource settings, which is frequently treated with antibiotics. The primary goal of a Shigella vaccine would be to reduce mortality and morbidity associated with Shigella diarrhea. However, ancillary benefits could include reducing antibiotic use and antibiotic exposures for bystander pathogens carried at the time of treatment, specifically for fluoroquinolones and macrolides (F/M), which are the recommended drug classes to treat dysentery. The aim of the study was to quantify the reduction in Shigella attributable diarrhea, all diarrhea, and antibiotic use in the first 2 years of life that could be prevented by a Shigella vaccine. METHODS AND FINDINGS: We used data from the Etiology, Risk Factors, and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED) study, a birth cohort study that followed 1,715 children with twice weekly surveillance for enteric infections, illnesses, and antibiotic use for the first 2 years of life from November 2009 to February 2014 at 8 sites. We estimated the impact of 2 one-dose (6 or 9 months) and 3 two-dose (6 and 9 months, 9 and 12 months, and 12 and 15 months) Shigella vaccines on diarrheal episodes, overall antibiotic use, and F/M use. Further, we considered additional protection through indirect and boosting effects. We used Monte Carlo simulations to estimate the absolute and relative reductions in the incidence of diarrhea and antibiotic use comparing each vaccination scenario to no vaccination. We analyzed 9,392 diarrhea episodes and 15,697 antibiotic courses among 1,715 children in the MAL-ED birth cohort study. There were 273.8 diarrhea episodes, 30.6 shigellosis episodes, and 457.6 antibiotic courses per 100 child-years. A Shigella vaccine with a mean vaccine efficacy of 60% against severe disease given at 9 and 12 months prevented 10.6 (95% CI [9.5, 11.5]) Shigella diarrhea episodes of any severity per 100 child-years (relative 34.5% reduction), 3.0 (95% CI [2.5, 3.5]) F/M courses for Shigella treatment per 100 child-years (relative 35.8% reduction), and 5.6 (95% CI [5.0, 6.3]) antibiotic courses of any drug class for Shigella treatment per 100 child-years (relative 34.5% reduction). This translated to a relative 3.8% reduction in all diarrhea, a relative 2.8% reduction in all F/M courses, a relative 3.1% reduction in F/M exposures to bystander pathogens, and a relative 0.9% reduction in all antibiotic courses. These results reflect Shigella incidence and antibiotic use patterns at the 8 MAL-ED sites and may not be generalizable to all low-resource settings. CONCLUSIONS: Our simulation results suggest that a Shigella vaccine meeting WHO targets for efficacy could prevent about a third of Shigella diarrhea episodes, antibiotic use to treat shigellosis, and bystander exposures due to shigellosis treatment. However, the reductions in overall diarrhea episodes and antibiotic use are expected to be modest (<5%).

Etiology, Presentation, and Risk Factors for Diarrheal Syndromes in 3 Sub-Saharan African Countries After the Introduction of Rotavirus Vaccines From the Vaccine Impact on Diarrhea in Africa (VIDA) Study.

BACKGROUND: Diarrheal disease is heterogeneous, including watery diarrhea (WD) and dysentery, some cases of which become persistent diarrhea (PD). Changes in risk over time necessitate updated knowledge of these syndromes in sub-Saharan Africa. METHODS: The Vaccine Impact on Diarrhea in Africa (VIDA) study was an age-stratified, case-control study of moderate-to-severe diarrhea among children <5 years old in The Gambia, Mali, and Kenya (2015-2018). We analyzed cases with follow-up of about 60 days after enrollment to detect PD (lasting ≥14 days), examined the features of WD and dysentery, and examined determinants for progression to and sequelae from PD. Data were compared with those from the Global Enteric Multicenter Study (GEMS) to detect temporal changes. Etiology was assessed from stool samples using pathogen attributable fractions (AFs), and predictors were assessed using χ2 tests or multivariate regression, where appropriate. RESULTS: Among 4606 children with moderate-to-severe diarrhea, 3895 (84.6%) had WD and 711 (15.4%) had dysentery. PD was more frequent among infants (11.3%) than in children 12-23 months (9.9%) or 24-59 months (7.3%), P = .001 and higher in Kenya (15.5%) than in The Gambia (9.3%) or Mali (4.3%), P < .001; the frequencies were similar among children with WD (9.7%) and those with dysentery (9.4%). Compared to children not treated with antibiotics, those who received antibiotics had a lower frequency of PD overall (7.4% vs 10.1%, P = .01), and particularly among those with WD (6.3% vs 10.0%; P = .01) but not among children with dysentery (8.5% vs 11.0%; P = .27). For those with watery PD, Cryptosporidium and norovirus had the highest AFs among infants (0.16 and 0.12, respectively), while Shigella had the highest AF (0.25) in older children. The odds of PD decreased significantly over time in Mali and Kenya while increasing significantly in The Gambia. CONCLUSIONS: The burden of PD endures in sub-Saharan Africa, with nearly 10% of episodes of WD and dysentery becoming persistent.

Mucosal Immune Profiles Associated with Diarrheal Disease Severity in Shigella- and Enteropathogenic Escherichia coli-Infected Children Enrolled in the Global Enteric Multicenter Study.

Enteropathogenic Escherichia coli (EPEC) and Shigella are etiologic agents of diarrhea in children <5 years old living in resource-poor countries. Repeated bouts of infection lead to lifelong morbidity and even death. The goal of this study was to characterize local mucosal immune responses in Shigella- and EPEC-infected children <5 years of age with moderate to severe diarrhea (MSD) enrolled in the Global Enteric Multicenter Study (GEMS). We hypothesized that infection with each of these pathogens would induce distinct gut mucosal immune profiles indicative of disease etiology and severity. To test this hypothesis, innate and adaptive immune markers were measured in stools from children with diarrhea due to EPEC, Shigella, or other organisms and in children who had no diarrhea. Shigella-positive diarrhea evoked robust proinflammatory and TH1/TH2 cytokine responses compared to diarrhea caused by EPEC or other organisms, with the exception of interleukin 5 (IL-5), which was associated with EPEC infection. The presence of IL-1ß, IL-4, IL-16, and tumor necrosis factor beta (TNF-ß) was associated with the absence of dysentery. EPEC-positive diarrhea evoked high levels of IL-1ß, vascular endothelial growth factor (VEGF), and IL-10. Granulocyte-macrophage colony-stimulating factor (GM-CSF) had opposing roles in disease severity, being associated with absence of diarrhea in EPEC-infected children and with dysenteric Shigella infection. High levels of antigen-specific antibodies were detected in the controls and children with Shigella without dysentery, which suggests a protective role against severe disease. In summary, this study identified distinct local immune responses associated with two clinically relevant diarrheagenic pathogens, Shigella and EPEC, in children and identified protective immune phenotypes that can inform the development of preventive measures. IMPORTANCE Shigella and enteropathogenic Escherichia coli are primary agents of moderate to severe diarrhea in children <5 years of age living in resource-poor countries. Repeated bouts of illness lead to lifelong health impairment and even death. Aiming to understand the local host immunity to these pathogens in relation to disease prognosis and to identify prophylaxis and therapeutic targets, we investigated innate and adaptive immune profiles in stools from children infected with EPEC with and without diarrhea, Shigella with and without dysentery, and controls in well characterized clinical samples obtained during the Global Enteric Multicenter Study. For the first time, we report pathogen-specific mucosal immune profiles associated with severity or absence of disease in children <5 years of age that can inform prevention and treatment efforts.

Diarrhea due to parasites: a short, updated point of view from the clinical setting.

Diarrhea represents a common manifestation of several gastrointestinal diseases. Infectious agents are the most common causes of diarrhea in developing countries, where the inadequate sanitation and hygiene are prevalent. In these countries, the scarcity of preventive measures as well as the limited health resources cause a substantial increase in incidence, morbidity and mortality due to infectious diseases, including diarrhea. Currently, with the availability of rapid and inexpensive air transportation millions of people travel for tourism, work and immigration from developing countries to industrialized countries and vice versa. This leads to a high number of imported pathogens such as parasites causing infectious diarrhea. Importantly, while most cases of parasitic diarrhea are short, mild and self-limited, other cases may be associated with chronic diarrhea and serious morbidity and mortality. The aim of the current review was to provide an update, from a clinician's point of view, of the main parasites causing diarrhea, with a focus on their diagnosis and management in the clinical setting.

Nontyphoidal Salmonella among Children under 5 Years Old in Sub-Saharan Africa and South Asia in the Global Enteric Multicenter Study.

Factors associated with nontyphoidal Salmonella (NTS) infection have not been well characterized to date. We aimed to compare the associated factors among children under age 5 years with NTS infection in sub-Saharan Africa and South Asia. Data from children having moderate-to-severe diarrhea (MSD) and asymptomatic children with NTS isolated from fecal specimens were extracted from the Global Enteric Multicenter Study (GEMS), conducted from December 2007 to March 2011. Compared with NTS-negative children, NTS-associated MSD cases in South Asia were associated with the presence of goat in the house (adjusted odds ratio [aOR]: 2.15; 95% confidence interval [CI]: 1.25-3.70) and handwashing after handling an animal (aOR: 2.26; 95% CI: 1.36-3.74). In sub-Saharan Africa, children with NTS associated MSD had a greater association with stunting (1.21 95% CI: 1.01-1.45), longer duration of diarrhea (aOR: 1.25 95% CI: 1.19-1.31); presence of cow in house (aOR: 1.54 95% CI: 1.09-2.16), handwashing after handling animal (aOR: 2.41 95% CI: 1.74-3.33). Drinking tube well water (aOR: 0.54 95% CI: 0.32-0.91), availability of toilet facility (aOR: 0.58 95% CI: 0.53-0.65), and handwashing before eating (aOR: 0.76 95% CI: 0.57-1.00) and after defecation (aOR: 0.80 95% CI: 0.69, 0.94) were found to be protective. The differentials between children of both regions having fecal NTS are distinct and underscore the need for policymaking for preventive and control strategies targeting stunted children.

Efficacy and safety of fixed-dose combination of drotaverine hydrochloride (80 mg) and paracetamol (500 mg) in amelioration of abdominal pain in acute infectious gastroenteritis: A randomized controlled trial.

BACKGROUND AND AIM: This randomized controlled trial was undertaken to assess efficacy and safety of fixed-dose combination of drotaverine hydrochloride (80 mg) and paracetamol (PCM) (500 mg). This was performed by comparison of mean pain intensity difference, total pain relief at 2 h, onset of pain relief, decrease in number of pain episodes, global improvement, and adverse effects. METHODS: A randomized double-blind controlled trial for adults between 18 and 59 years of either gender with acute infectious diarrhea (≥ 3 unformed, watery, or soft stools with symptoms at least within the last 24 h preceding randomization with duration of illness not more than 72 h) with moderate-to-severe abdominal pain. Participants were treated with either a fixed-dose combination of oral drotaverine hydrochloride (80 mg) and PCM (500 mg) or oral PCM (500 mg) three times a day for 3 days. RESULTS: Of 252 (126 in each group) participants, all received at least one dose of medication. Two hundred forty-two completed the study. Mean pain intensity difference at 60 min after administration of study medication by Visual Analogue Scale (VAS) and total pain relief at 2 h using both VAS and Verbal Rating Scale showed statistically significant improvement in drotaverine hydrochloride (80 mg) and PCM (500 mg) group. The onset of pain relief was also significantly better in drotaverine hydrochloride (80 mg) and PCM (500 mg) group when using VAS. CONCLUSION: Fixed-dose combination of drotaverine hydrochloride (80 mg) and PCM (500 mg) is an effective and safe antispasmodic agent in abdominal pain associated with acute infectious gastroenteritis.

Aspectos clínicos y epidemiológicos de las enfermedades diarreicas agudas secretoras. Hospital General Docente "Juan B. Viñas González". 2014 / Clinical and epidemiological aspects of acute diarrheal secretory diseases. General Hos-pital "Juan B. Viñas González". 2014

Se realizó un estudio observacional, descriptivo, de corte transversal, con una población de estudio compuesta por 634 pacientes pediátricos con cuadro de diarrea aguda secretoria, que fueron ingresados en el Hospital General Docente "Juan B. Viñas González" de Palma Soria-no, Cuba, durante el período enero-diciembre, 2014. Los resultados arrojaron un predominio del rango de edades de 1 a 4 años, para un 30.4%; la mayoría de ellos, residentes en zonas rurales (64.5%), donde la calidad del agua de consumo no era la adecuada (46.8%) y la dispo-sición de las excretas tenían deficiencias en un 45.1% de los casos. Los síntomas predomi-nantes fueron fiebre y vómitos para un 47.4% y 45 % respectivamente y los signos fueron: los ojos hundidos en un 57.4% y sequedad de las mucosas (45.1%), como complicaciones se reportó: la deshidratación con 55.2%, la hipoglucemia (50.9%) y la acidosis metabólica (34.9%), presentando en ocasiones, un niño más de una complicación, lo que motivó un 35% de ingresos en los servicios de cuidados progresivos; sin embargo, no hubo fallecidos por esta causa en el tiempo estudiado.

An observational, descriptive, and cross-sectional study was carried out. 634 pediatric patients with acute diarrhea were the study population who were admitted to the General Hospital "Juan B. Viñas González" of Palma Soriano, Cuba, during the period January-De-cember 2014. The results showed a predominance of the age range between 1 and 4 years (30.4%); most of them, residents in rural areas (64.5%) where the quality of drinking water was not adequate (46.8%) and the disposal of excreta were deficient in 45.1% of cases. The predominant symptoms were fever and vomiting 47.4% and 45% respectively and the signs were: the sunken eyes (57.4%) and dryness of the mucous membranes (45.1%). There were some complications such as: dehydration (55.2%), hypoglycaemia (50.9%) and metabolic acidosis (34.9%); it was sometimes presented a child with more than one complication, which motivated a 35% of income in the progressive care services. However, there were no deaths due to this cause in the time studied.

Isoflavones and gastrointestinal infection: Two potential triggers for reversible cerebral vasoconstriction syndrome.

Background Reversible cerebral vasoconstriction syndrome (RCVS) is an important differential diagnosis of singular or recurrent thunderclap headache. Prognosis is generally good, however complications of the transient segmental vasospasms of cerebral arteries such as stroke, subarachnoidal hemorrhage and brain edema may worsen the clinical outcome. Although the exact pathomechanism is still unclear, various vasoactive substances and conditions (e.g. post partum) have been identified as triggering RCVS. Cases We report on the clinical course and management of two cases of typical RCVS that were associated with two different precipitants previously not described: A gastrointestinal infection and isoflavones, which are phytoestrogens used for menopausal vasomotor symptoms. Discussion In the case of gastrointestinal infection, either systemic inflammatory processes might lead to disturbances of vascular tone, or the repetitive vomiting that resembles Valsalva manoeuvers known to trigger RCVS. In the case of isoflavone intake, it may be their estrogenic potential that induces dysregulation of cerebral arteries, a mechanism known from other states of hormonal change such as post-partum angiopathy. However, the association of both precipitating factors with RCVS in our two cases is not a proof for a causal relationship, and there may have been additional potential triggers for RCVS. Conclusion In patients with (gastrointestinal) infection and concomitant thunderclap headache, RCVS should be considered as an important differential diagnosis due to its major complications. Since RCVS may be triggered by various vasoactive substances, taking the medical history should always include over-the-counter drugs and dietary supplements (such as the isoflavones) beside the regular medication.

Trichuris dysentery syndrome: Do we learn enough from case studies?

Trichuris Dysentery Syndrome (TDS) is a severe persistent trichuriasis associated with heavy worm build-up in the colon that continues to be neglected and underestimated in endemic countries. Trichuriasis is most prevalent in children in tropical countries, and that increases the risk of TDS. We reported a series of four preschool children of both genders chronically having TDS over a period ranging from several months to years presenting with anaemia. The hemoglobin levels ranged from 4.6 to 9.1 g/dl on first admissions. Despite treatment, the cases were reported to have failure to thrive with persistent anaemia. It was concluded that TDS should be considered in endemic areas among children presenting with chronic bloody diarrhea and anaemia.

Predictors of the risk of malnutrition among children under the age of 5 years in Somalia.

OBJECTIVE: To investigate the predictors of wasting, stunting and low mid-upper arm circumference among children aged 6-59 months in Somalia using data from household cross-sectional surveys from 2007 to 2010 in order to help inform better targeting of nutritional interventions. DESIGN: Cross-sectional nutritional assessment surveys using structured interviews were conducted among communities in Somalia each year from 2007 to 2010. A two-stage cluster sampling methodology was used to select children aged 6-59 months from households across three livelihood zones (pastoral, agro-pastoral and riverine). Predictors of three anthropometric measures, weight-for-height (wasting), height-for-age (stunting) and mid-upper arm circumference, were analysed using Bayesian binomial regression, controlling for both spatial and temporal dependence in the data. SETTING: The study was conducted in randomly sampled villages, representative of three livelihood zones in Somalia. SUBJECTS: Children between the ages of 6 and 59 months in Somalia. RESULTS: The estimated national prevalence of wasting, stunting and low mid-upper arm circumference in children aged 6-59 months was 21 %, 31 % and 36 %, respectively. Although fever, diarrhoea, sex and age of the child, household size and access to foods were significant predictors of malnutrition, the strongest association was observed between all three indicators of malnutrition and the enhanced vegetation index. A 1-unit increase in enhanced vegetation index was associated with a 38 %, 49 % and 59 % reduction in wasting, stunting and low mid-upper arm circumference, respectively. CONCLUSIONS: Infection and climatic variations are likely to be key drivers of malnutrition in Somalia. Better health data and close monitoring and forecasting of droughts may provide valuable information for nutritional intervention planning in Somalia.

[Hemolytic anemia and dysenteric syndrome: a case of ulcerative colitis]. / Anemie hémolytique et syndrome dysentérique : à propos d'un cas de rectocolite ulcéro-hémorragique.

A 53-years-old man has a dysentery since two weeks. The blood test shows Coombs-positive hemolytic anemia and inflammation. Autoimmune hemolytic anemia (AIHA) is treated with corticosteroid. A colonoscopy reveals an ulcerative colitis. The evolution of the patient is complicated by a spontaneous digestive perforation treated by total proctocolectomy. After this intervention, there is a resolution of the AIHA and the patient is gradually weaned from corticosteroids. AIHA is a rare extra-intestinal manifestation of inflammatory bowel disease essentially ulcerative colitis. Identification of this cause of secondary AIHA is important for the therapeutic strategy. However treatment is nonspecific and based on low levels of evidence.

[Acute diarrhea]. / Akute Diarrhoe.

Diarrhea, defined as three or more loose or watery stools per day, represents a frequent problem in outpatients as well as inpatients. As most of the patients with acute diarrhea show a self-limiting disease course, the main challenge for the physician is to discriminate patients for whom symptomatic therapy is sufficient from those with severe disease course and threatening complications. This review aims to provide a practical guidance for such decisions.

[Campylobacter fetus bacteremia complicating a dysenteric syndrome in a young epileptic]. / Bactériémie à Campylobacter fetus compliquant un syndrome dysentérique chez un jeune épileptique.

Campylobacter fetus bacteremia is rare and occurs mainly in elderly and immunosuppressed patients. We report an original observation of C. fetus bacteremia complicating acute mucoid diarrhea in a young epileptic with no known risk factors. Our observation suggests that antiepileptic treatment could increase the risk of blood-borne of C. fetus infection.

[Infectious diarrhea - key reflections for approaching this problem]. / Infektiöser Durchfall.

Diarrhea is a frequent and complex entity which is caused by a large number of infectious and non-infectious reasons. A detailed clinical and epidemiological history will define whether an additional laboratory work-up and treatment is indicated. Acute diarrhea is predominantly caused by viral or bacterial pathogens and is usually of short duration without any therapeutic intervention. A parasitic or non-infectious cause must be primarily considered if the diarrhea persists over two weeks. Work-up of stool specimens must target the most likely pathogens or other causes considered. The key element of treatment of acute diarrhea is rehydration. An empirical anti-infective therapy may be considered in critically ill patients, persistent or chronic diarrhea as well as in selected epidemiological or risk situations.

La diarrhée est une maladie fréquente et complexe qui est causée par de nombreuses raisons infectieuses ou non-infectieuses. Une anamnèse détaillée qui focalise sur la clinique et les circonstances épidémiologiques va définir si des examens du laboratoire supplémentaires et si un traitement sont indiqués. La diarrhée aiguë est surtout dûe à des origines virales ou bactériennes et est normalement de courte durée même sans traitement. Si la diarrhée dure plus que deux semaines, il faut considérer des parasites ou des raisons non-infectieuses à l'origine de la diarrhée. Un diagnostic des selles ciblé s'impose. Le traitement clé de la diarrhée aiguë est la réhydratation. Un traitement empirique est indiqué chez les patients très malades, chez des patients avec une diarrhée persistante ou chronique ainsi que dans des situations spéciales épidémiologiques ou à risque.

Severe chronic iron deficiency anaemia secondary to Trichuris dysentery syndrome - a case report.

Trichuris dysentery syndrome is caused by Trichuris trichiura which contributes to one of the most common helminthic infections in the world. It is associated with heavy colonic infection that manifests as mucoid diarrhoea, rectal bleeding, rectal prolapse, iron deficiency anaemia, and finger clubbing. Here, we report a case of trichuris dysentery syndrome complicated with severe chronic iron deficiency anaemia in a 4-year-old girl who required blood transfusion. The nematode was visualized on stool microscopic and colonoscopic examination. A longer duration of anti-helminthic treatment is required to achieve effective and better outcome.
