The aetiology of rotavirus and adenovirus in acute gastroenteritis was studied in a prospective series that comprised 283 children admitted consecutively with diarrhoea during a 1-year period. Rotavirus was associated in 49% of the cases by solid-phase radioimmunoassay and electron microscopical examination of stool specimens, or by serology. Adenovirus was detected by radioimmunoassay in the stool specimens of 29 (11%) patients, including 8 cases of possible dual infection with rotavirus. Rotavirus infections showed a typical age distribution and seasonal clustering between January and June, whereas the adenovirus-associated cases did not form a distinctive subgroup. Enteropathogenic bacteria were found in 10% of cases, and were nearly as common in association with rotavirus infection as not. Respiratory symptoms accompanied diarrhoea in 34% of the patients with rotavirus and in 25% of those with neither rotavirus nor adenovirus. Therefore we could not confirm the existence of a 'rotavirus syndrome', nor could we confirm an association of respiratory symptoms with rotavirus infection. Use of antibiotics before the onset of diarrhoea was more common among those with non-viral diarrhoea (23%) than in the rotavirus group (13%). Rotavirus infections appeared to be common among cases of 'antibiotic-induced' diarrhoea.

Fastidious enteric adenovirus have recently been recognized as an important cause of acute gastroenteritis in young children. Their inability to grow in vitro has hampered classification by conventional methods. With modern immunological and chemical techniques the enteric adenoviruses have been shown to be distinct from the 39 established human adenovirus serotypes. In a prospective study of the viral, bacterial and parasitic aetiology of acute gastroenteritis 410 children and 205 age-matched controls were studied. An enteropathogenic agent was detected in 67% of the diarrhoeic patients and 57% were of viral origin. Rotavirus was the major agent found in 43% of the patients whereas adenovirus was found in 13%. Of the 50 adenovirus specimens, so far fully characterized by electron microscopy, ELISA-assays, DNA-restriction analysis and isolation studies 70% were identified as enteric adenoviruses. Two serotypes, adeno 40 and 41, were detected representing the new subgroups F and G. Twelve of 17 paired serum specimens, from children with enteric adenovirus showed a significant rise in hemagglutination inhibition titers. Infection with enteric adenoviruses showed 2 small seasonal peaks in summer and late winter. Infection occurred early in life, 85% of the children aged less than 3 years. Diarrhoea was the main symptom with an average duration of 9 days. Adenovirus type 41 seemed to cause diarrhoea of longer duration. Fever and vomiting was mild with a mean of 2 days. Respiratory symptoms occurred in 20% of the cases. The incubation period could be estimated as 7 days. Virus was excreted for 10-14 days.

Adenovirus (AdV) is a common cause of respiratory illness in both children and adults. Respiratory symptoms can range from those of the common cold to severe pneumonia. Infection can also cause significant disease in the immunocompromised and among immunocompetent subjects in close quarters. Fortunately, infection with AdV in the normal host is generally mild. This is one reason why its initial use as a gene-therapy vector appeared to be so promising. Unfortunately, both innate and adaptive responses to the virus have limited the development of AdV vectors as a tool of gene therapy by increasing toxicity and limiting duration of transgene expression. This article will focus on the innate immune response to infection with wild-type AdV and exposure to AdV gene-therapy vectors. As much of the known information relates to the pulmonary inflammatory response, this organ system will be emphasized. This article will also discuss how that understanding has led to the creation of new vectors for use in gene therapy.
