This article reviews current recommendations of therapy with antidiarrheal compounds and antimicrobial agents for acute infectious diarrhea in children. In most infants and children with acute infectious diarrhea, treatment with antidiarrheal compounds is not indicated. Many of these compounds interfere with identification of enteropathogens in stool specimens, and the antimotility class has an overdose potential. Antimicrobial therapy is given to reduce symptoms and to prevent the spread of infection by decreasing fecal shedding of organisms. Although effective therapy is not available for patients with enteric viruses, Cryptosporidium, and Microsporidium, therapy is useful for children with amebiasis, antimicrobial-associated colitis, cholera, giardiasis, various forms of Escherichia coli diarrhea and Salmonella disease, isosporiasis, shigellosis, and strongyloidiasis. For several other conditions, antimicrobial therapy is of questionable benefit (infection with Campylobacter jejuni or Yersinia enterocolitica, intestinal salmonellosis and enterohemorrhagic E. coli infection). Compounds such as the fluoroquinolones, which are effective in the treatment of acute infectious diarrhea in adults, are not approved for use in children because of potential side effects. Many bacterial, viral, and parasitic organisms cause acute infectious diarrhea; appropriate antimicrobial therapy requires the accurate, rapid identification of the offending enteropathogen. In children with an underlying illness such as acquired immunodeficiency syndrome, manifestations may be prolonged, severe, and recurrent despite appropriate therapy.

Patients infected by Salmonella, Shigella, Giardia, Campylobacter, Yersinia, and Hepatitis A virus were interviewed during a 15-month period to evaluate the benefit of intensive follow-up, to assess the proportion of cases who had contact with children less than four years of age, and to determine risk factors. Of 746 reported infections, we interviewed 345 patients (46%) and identified 199 other ill people. Follow-up of sporadic, passively reported cases required considerable resources, but no large outbreaks were uncovered. Investigation of patients [N = 103 (43%)] who had contact with children less than four years of age, or children who attended daycare centers often resulted in identification of additional illness, especially for cases of giardiasis. Primary health care providers can play a key role in reducing enteric disease by increasing efforts to identify illness among daycare and family contacts of their patients.

Clostridium difficile has been associated with diarrhea in hospitalized patients receiving antibiotic therapy, and may be nosocomially acquired. Rehabilitation hospital inpatients may require frequent antibiotic intervention and are thus at risk, though few reports of epidemics at such centers have been published. This study describes the evaluation and prevalence of C difficile-related disease, among rehabilitation hospital inpatients. A retrospective review was conducted of all diarrhea evaluations performed among inpatients in two freestanding rehabilitation hospitals over a two-year period. A total of 303 laboratory tests were performed among the 115 patients evaluated. C difficile was determined to be the etiologic agent of diarrhea in 25% of patients undergoing enteric evaluation, and in 39% of patients specifically assayed for C difficile toxin B. Giardiasis was detected in one patient, and no evidence of Salmonella, Shigella, Campylobacter, or Yersinia infection was found. The estimated prevalences for diarrhea and C difficile-related disease were 3.7% and 1.1%, respectively. Thus, C difficile is an important cause of diarrhea among rehabilitation hospital inpatients, though its true prevalence may be underestimated due to inadequate diagnostic evaluation. Enteric bacterial pathogens such as Campylobacter, Salmonella, Shigella, Yersinia, and Giardia are insignificant causes of diarrhea among these patients. Elimination of routine testing for these pathogens would reduce costs without compromising diagnostic utility. Diagnostic evaluation should include C difficile toxin assay, and if positive, appropriate therapy instituted.

Data from the first sentinel site (Waterloo Region, Ontario) of the Canadian Integrated Enteric Disease Surveillance System (C-EnterNet) were used in a secondary-based case-control study of laboratory-confirmed Cryptosporidium infections to study the role of various exposure factors. The incidence of cryptosporidiosis in Waterloo Region was almost double both the provincial and national rates. Persons ill with one of nine other enteric infections (amoebiasis, campylobacteriosis, cyclosporiasis, giardiasis, listeriosis, salmonellosis, shigellosis, verotoxigenic E. coli infections, yersiniosis) captured by the surveillance system were used as the control group. Of 1204 cases of enteric illness in the sentinel area between April 2005 and December 2007, 36 cases and 803 controls were selected after excluding outbreak and international travel-related cases. Univariable analyses (Pearson chi2 and Fisher's exact tests) and multivariable logistic regression were performed. Results of the multivariable analysis found that cryptosporidiosis was associated with swimming in a lake or river (OR 2.9, 95% CI 1.2-7.4), drinking municipal water (a potential surrogate for urban respondents vs. rural) (OR 2.4, 95% CI 1.04-5.7), and having a family member with a diarrhoeal illness (OR 2.9, 95% CI 1.3-6.4).
