The efficacy of trimethoprim-sulfamethoxazole (TMP-SMX) and placebo were compared in a randomized double-blind study of 141 Mexican children with acute diarrhea. Patients who met specific entry criteria received TMP-SMX or an identical appearing placebo for 5 days. Stools were examined for bacterial, viral, and parasitic pathogens. Enterotoxigenic Escherichia coli were the most commonly isolated pathogens (22% of total). Patients given TMP-SMX had a significantly shorter time to "last illness stool" than did those given placebo, but no difference in number of unformed stools in 5 days was found between treatment groups. However, TMP-SMX significantly shortened the illness in patients with fever or many fecal leukocytes. When stool cultures positive for any bacterial pathogen or for enterotoxigenic E. coli were analyzed as separate groups, a significantly faster recovery was observed in patients given TMP-SMX. TMP-SMX is efficacious in the treatment of Mexican children with diarrhea and culture-proved bacterial infection or when the clinical signs and symptoms suggest bacterial enteritis.

Acute diarrhea in adults is usually caused by bacterial infection, parasitic infestation, food poisoning, or drugs. In this review, we summarize the pros and cons of medical therapies, point out certain areas of controversy, and propose a rationale for early intervention. Discussion is limited to the use of antidiarrheal agents and antibiotics in acute infectious diarrhea.

The aim of this study was to describe the etiology, morbidity and hospitalization costs associated with acute diarrhea among hospitalized children in Greece. During 1999, 294 hospitalized children (median age 1 y) with acute diarrhea were prospectively studied. Bacterial and viral enteropathogens were detected in 100 (34%) and 37 (12.5%) patients, respectively; 17 (6%) patients had mixed infections. Isolated agents included Salmonella spp. (43 patients; 15%), rotavirus (32; 11%), Campylobacter spp. (26; 9%), enteropathogenic Escherichia coli (16; 5.5%), Shigella spp. (11; 4%), Aeromonas spp. (7; 2.5%), adenovirus (6; 2%), Yersinia enterocolitica (6; 2%), enterohemorrhagic Escherichia coli (2; 0.5%) and Giardia lamblia (1; 0.5%). Of the patients with bacterial infection, 70% were admitted between April and September 1999. A rotavirus-associated peak was noted in March. Patients with a bacterial infection were hospitalized for longer periods than those with viral infections. It is concluded that bacterial enteropathogens account for one-third of admissions due to acute diarrhea among children in Greece and are associated with significant hospitalization costs. Rotavirus is also a frequent cause of acute diarrhea necessitating hospitalization.

The present study, conducted from March 1998 to July 2000, determined the etiology of acute diarrhea in 253 young children and infants from Cartagena and Sincelejo, Colombia. In 253 stool samples, the following enteric pathogens were recovered: rotavirus type A (36.6%) as the major agent, Salmonella spp (9.0%), Shigella spp (8.0%), enteric pathogenic Escherichia coli (6.0%), enteric hemorragic Esc. coli (2.8%), Providencia alcalifaciens (2.8%), Aeromonas hydrophila (2.0%), Yersinia enterocolitica (0.8%), Entamoeba hystolitica (10%), Giardia lamblia (4%), Endolimax nana (3.2%), Ascaris lumbricoides (2.8%), Ent. coli (1.2%), Balantidium coli (0.8%), Blastocystis hominis (0.8%), Dypilidium caninum (0.4%) and hook worm sp. (0.4%). Infection with more than one pathogen occurred in 96 (37.9%) patients. Rotavirus and enteric pathogenic Esc. coli were frequent. Concurrent infection by more than one parasite occurred in 18.6% of the infants. Most rotavirus infections (76.7%) occurred in infants under 12 months. Vomiting, severe dehydration and fever were frequent in children with rotavirus infection. At least one fecal marker of inflammatory diarrhea was registered in patients with bacterial infection. To our knowledge, this is first report of P. alcalifaciens associated with infantile diarrhea in Colombia and the first description of Esc. coli O157:H7 and Y. enterocolitica in our region.

Group A rotaviruses are the major cause of diarrhea in young children worldwide. From March 2001 to April 2002, 836 children less than 5 years of age were investigated in Hanoi, Vietnam. This included 587 children with diarrhea and 249 age-matched controls. Group A rotavirus was identified in 46.7% of the children with diarrhea and 3.6% of the controls, which was a significant difference. Within the diarrhea group, the highest prevalence was seen in children from 13 to 24 months of age, and the prevalence was higher in males than in females. The symptoms of acute diarrhea caused by rotavirus were watery diarrhea, vomiting, fever, and dehydration. A higher prevalence of rotavirus detection was obtained for children who had all of these symptoms, followed by those who had diarrhea with vomiting-dehydration, fever-dehydration, and dehydration. The high rates occurred from September to December, although the infection was encountered all year round. In 58 patients (21.2% of the rotavirus-infected children), rotavirus infection was detected in association with either diarrheagenic Escherichia coli or Shigella spp. The most frequent combinations were rotavirus-enteroaggregative E. coli and rotavirus-enteropathogenic E. coli. At least one enteropathogen was identified from about 64% percent of the samples. The bacterial infection may not have given rise to clinical symptoms of such severity. The present study demonstrates the burden of rotavirus diarrhea in Hanoi, Vietnam. Continuous surveillance of diarrhea caused by rotavirus in young children would play an important role in diagnosis, treatment, and prophylaxis in order to improve the health of children in Vietnam.

The prognosis of acute diarrhoea in infants is most often satisfactory in industrialized countries. However, it has been estimated that 10 to 15 children die every year in France from acute dehydration due to acute diarrhoea. In spite of an increasing use over the least few years, oral rehydration solutions (ORS) are used in only 70% of infants presenting with acute diarrhoea. The use of homemade ORS, plain water or fizzy drink should be strictly avoided. In case of acute diarrhoea there is no indication to stop breastfeeding or the use of infant formula for more than 4 hours. Lactose intolerance is observed in only 5-10% of infants. Lactose free formulae should only be used in infants with severe, persistent or recurrent diarrhoea. Under 3-4 months of age, infants with severe diarrhoea should receive for a period of 2-4 weeks lactose free protein hydrolysate formulae. Racecadotril is the only drug with anti-diarrheal properties, with a reduction of the stool output of 50%. Oral antibiotics should only be used in case of Shigella infection or in case of bacterial infection with severe sepsis or underlying debilitating disease. Oral Rotavirus vaccine, that is not reimbursed yet in France, has been shown to dramatically reduce the number of severe cases of diarrhoea with dehydration, and has been associated with a striking reduction of both morbidity and mortality, as well as of the number of hospitalisations during periods of epidemics.

This retrospective study was conducted during January to September in the year 1997. Three hundred and forty nine stool samples were collected from diarrhoea patients from different places of Kathmandu valley and examined at National Public Health Laboratory (NPHL), Teku, Kathmandu. Acute diarrhoea becomes epidemic in rainy season and is a major public health problem of the city. In this study, people with poor hygiene practice and poor education were infected more than other people. Among the 349 patients with the gastrointestinal disease, 26.0% were found to have bacterial infection. Out of which, 88 (25.1%), one (0.28%), one (0.28%), and one (0.28%) were found to be Vibrio cholerae 01, Vibrio cholerae 0139, Shigella dysenteriae and Escherichia coli respectively. Cholera cases were found almost throughout the year in the city though the numbers increased during the rainy season. It was highest during July (34.6%) followed by August (32.35%), September 32% and June (6.89%). The uncommon species of Vibrio i.e. Vibrio cholerae 0139 was also found in the study. Higher prevalence was found in urban areas (83.52%) than in rural areas (16.48%). Antimicrobial susceptibility testing of bacterial isolates showed that Ciprofloxacin (97.85%) was found to be the most effective antibiotic followed by Tetracycline (92.34%), Erythromycin (92.34%), Norfloxacin (93.34%), Cholramphenicol, Ampicillim, but Cotrimoxazole were found to be resistant to all isolated Vibrio cholerae.

Acute infectious gastroenteritis is one of the most common diseases among all ages, particularly in developing countries. The pathogen spectrum may differ among different regions and seasons. To investigate the etiology of acute diarrhea in Shenzhen, a prospective study was conducted from August 2014 to September 2015. Stools from 412 patients with diarrhea (286 of whom were adults) including the general epidemiological information of the patients were collected. The 19 pathogens were detected by conventional culture method or multiplex PCR assay, which included five viruses (rotavirus, adenovirus, sapovirus, norovirus, and astrovirus), 11 bacterial pathogens (Salmonella, Campylobacter jejuni, Shigella, Listeria monocytogenes, Vibrio parahaemolyticus, Vibrio cholera, Enterohemorrhagic (EHEC), enteropathogenic (EPEC), enteroinvasive (EIEC), enterotoxigenic (ETEC); and enteroaggregative Escherichia coli (EAEC)) and three parasites (Entamoeba histolytica, Giardia lamblia, and Cryptosporidium parvum). A potential pathogen and coinfection was found in 41.5 and 7.0% of cases, respectively. The bacterial infection was the dominant cause of diarrhea (32.3%), and the three most frequently identified organisms were Salmonella (12.1%), ETEC (8.0%), and Campylobacter jejuni (4.9%). Salmonella enteritidis was the leading serotype of Salmonella sp. Norovirus (8.3%) and sapovirus (2.2%) were the most common viral pathogens, followed by adenovirus (1.5%) and rotavirus (1.2%). No EHEC, L. monocytogenes, V. cholera, Shigella, and parasites were found. The single most important causes of diarrhea were Salmonella spp. and Campylobacter jejuni, which points toward the need for testing and surveillance for these pathogens in this region.

Objective: To explore pathogen spectrum constitution of acute diarrhea in outpatient and emergency of Zhejiang Province, and provide basis for treatment, prevention and control of the disease. Methods: During January 2009 to December 2014, we selected seven sentinel hospitals in different regions of Zhejiang, monitored and researched on pathogen spectrum in patients with acute diarrhea from outpatient and emergency. We recorded patients' personal basic information, the main symptoms and signs, and collected stool samples (5 g). Eight kinds of bacteria (Vibrio cholerae, Shigella spp., Salmonella spp., Diarrheagenic E. coli, Vibrio parahaemolyticus, Aeromonas hydrophila, Yersinia enterocolitica and Plesiomonas shigelloides) and five kinds of viruses (Rotavirus, Norovirus, Sappovirus, Astrovirus and Adenovirus) were detected. Chi-square test and Fisher's exact probability method were used to compare different characteristics of patients with single bacterial infection, single virus infection and multiple infection (bacteria-bacteria, bacteria-viruses, virus-virus). Results: During 2009 to 2014, 9 364 fecal samples from acute diarrhea patients were collected and tested, among which 3 500 cases were tested positive, with total positive rate of 37.38%. Positive rates of bacteria and viruses were 13.14% (1 230 cases) and 20.75% (1 943 cases), respectively. Mixed infection positive rate of multiple pathogens was 3.49% (327 cases). Positive rate of Vibrio parahaemolyticus (5.96% , 558 cases) was the highest among bacterial pathogens, followed by pathogenic Escherichia coli (3.86%, 361 cases). Viruses were mainly Norovirus (10.73%, 1 005 cases) and rotavirus (8.35%, 782 cases). A big difference existed in diarrheogenic pathogen spectrum between patients less than 15 years old and patients equal or older than 15 years old. Pathogens for patients less than 15 years old were mainly virus, with the positive rate of 32.69% (1 014 cases). However, the positive rate of bacteria was 16.86% (1 056 cases) in patients equal or older than 15 years old. Single bacterial infection was highest in age group of 25-34 years old (18.62%, 302 cases) , single virus infection was highest in age group of 1-4 years old (41.12%, 435 cases) , and mixed infections of multiple pathogens were mainly existed in age group of 1-4 years old (7.37%, 78 cases) . Pathogen positive rate were increasing year by year. Pathogen positive rate of patients with acute diarrhea has obvious seasonality, with single bacterial infection being highest during July to September and single virus infection being highest during December to March. Pathogen spectrum of outpatient and emergency patients with acute diarrhea in Zhejiang Province changed a little from 2009 to 2014, mainly rotavirus (22.34% (782/3 500)), norovirus (28.71% (1 005/3 500)), vibrio parahaemolyticus (15.92% (558/3 500)) and Escherichia coli (10.31% (361/3 500)). However, pathogen spectrums in different years owned different features. Conclusion: Common pathogens in outpatient and emergency patients with acute diarrhea in Zhejiang Province were tested with significant seasonal epidemic law. The composition of pathogenic spectrum was variant in different age group. Constitutes of major pathogen spectrum in different years differed a little.
