Transient exocrine pancreatic insufficiency as a possible complication of an enterovirus infection.

UNLABELLED: Exocrine pancreatic insufficiency is an exceptional problem in children, mostly associated with diseases like cystic fibrosis, Shwachman-Diamond syndrome or chronic pancreatitis, as is the case in idiopathic fibrosing pancreatitis. Many viral infections are known to cause acute pancreatitis. Most of them, however, are transient with no remaining damage. The differential diagnosis of persisting diarrhoea after gastrointestinal infection does not routinely include a search for exocrine pancreatic insufficiency. CONCLUSION: This is the first description of a child with a transient but severe exocrine pancreatic insufficiency probably induced by an ordinary enterovirus infection

Four cases of vesicular lesions in adults caused by enterovirus infections.

Echovirus types 4 and 33 and coxsackievirus type B1 were recovered from vesicular lesions in four adults. Patient 1 had cutaneous localized vesicles, patient 2 had a recurrent cutaneous vesicle, and patients 3 and 4 had mucosal vesicles. Three of the patients were suspected of having herpesvirus lesions. One of the patients was a human immunodeficiency virus type 1-seropositive man, and the enterovirus infection was the first clinical manifestation. Our results underline the importance of virological diagnosis before treatment with acyclovir, especially for immunocompromised patients.

Immunofluorescent IgG and IgM antibodies in human sera by enterovirus infections.

IgG and IgM antibodies to selected enterovirus serotypes (P2, CB 1-5, E2, 4, 20), to prototype collection strains and to fresh isolates were examined by immunofluorescence in paired sera of 11 children and 4 adults in whom enterovirus had been isolated, or a rise of specific antibodies had been proved by neutralization test. One six-month- and one seven-month-old child had antibodies of both classes to the isolated virus strain and to poliovirus only. Children from eight month onwards and adults had antibodies to the majority of enterovirus serotypes tested. Among all enteroviruses tested, heterologous reactions were observed not only with IgG but also with IgM class antibodies.

Cell mediated responses in a porcine enterovirus infection in piglets.

Sixteen pathogen-free piglets were infected orally with procine enterovirus strain T80 and the cell mediated response to the virus was measured at intervals after infection. Five uninfected piglets were used as controls. Indirect macrophage migration inhibition tests were performed with lymphocytes from blood, ileal lamina propria and mesenteric lymph node. Blood lymphocyte culture supernatants showed no consistent T80 specific on macrophage migration, suggesting the absence of a systemic cell-mediated response. Ileal lamina propria lymphocyte culture supernatants showed irregular migration stimulation. The mesenteric lymph node lymphocyte culture supernatants produced migration inhibition at seven days postinfection, followed by stimulation of migration from ten to 22 days postinfection. Subsequently, migration was again inhibited from 24 to 31 days postinfection. Mesenteric lymph node lymphocyte culture supernatants contained only trace amounts of interferon activity at 28 and 31 days postinfection. It was concluded that the cell mediated responses in this infection were weak and localized and not associated with significant antiviral activity.

Identification of genes involved in the host response to enterovirus 71 infection.

Enterovirus 71 (EV71) infection may be asymptomatic or may cause diarrhea, rashes, and hand, foot, and mouth disease (HFMD). However, EV71 also has the potential to cause severe neurological disease. To date, little is known about the molecular mechanisms of host response to EV71 infection. In this report, we utilized cDNA microarray to profile the kinetics and patterns of host gene expression in EV71-infected human neural SF268 cells. We have identified 157 genes with significant changes in mRNA expression and performed hierarchical clustering to classify these genes into five different groups based on their kinetics of expression. EV71 infection led to increases in the level of mRNAs encoding chemokines, proteins involved in protein degradation, complement proteins, and proapoptotis proteins. cDNA microarray expression comparisons of EV71- and mock-infected cells also revealed the down-regulation of several genes encoding proteins involved in host RNA synthesis. Expression of interferon-regulated proteins was increased early in the infection and then decreased. Expression of proteins involved in cellular development and differentiation, some oncogenes, and transcription and translation regulators were suppressed and then stimulated late in the infection. Our findings illustrate the overall host response to EV71 infection, and will aid in understanding the host response to this virus.

Detection of neutralizing IgM antibodies in the diagnosis of enterovirus infections.

Data are presented of IgM detection by a neutralization test used routinely in 1,062 patients. Antigens isolated during the period of investigation were EV4, EV7, EV11, EV18, EV21, EV24, EV33, CA9, CB2, CB4, and CB5. No difference was observed in the distribution of IgM-positive sera according to age and sex. Total antibodies are at higher titres when IgM antibodies are present. Polytypic IgM responses are not frequent (less than 10%). The frequency of the IgM-positive sera for a given serotype correlated with the frequency of isolates for the serotype except for CA9. Other than for babies under age 6 months, IgM detection is more frequent than is isolation. The susceptibility of the elderly and the frequency of IgM-positive sera among adults over age 40 years suggests possible underestimation of enterovirus infections in adults. The duration of IgM remains a major question.

Association of clinical presentation, laboratory findings, and virus serotypes with the presence of meningitis in hospitalized infants with enterovirus infection.

One hundred eight hospitalized infants with enteroviral infections were studied to determine the association of clinical presentation, laboratory findings, and virus serotypes with the presence of meningitis. Of 108 infants, 55 (51%) had meningitis. Clinical manifestations on admission did not distinguish between infants with and those without meningitis. Echoviruses 30 and 11 and coxsackie virus B were frequently associated with meningitis (34/38; 90%) whereas echoviruses 18, 24, and 25 were not (5/35; 4%). The virus isolation rate was directly proportional to the number of leukocytes in cerebrospinal fluid: 5 of 58 (9%) when up to 9 cells/mm3 were found, 10 of 21 (48%) when 10 to 99/mm3 cells were found, and 25 of 29 (86%) when greater than equal to 100 cells/mm3 were found. Meningitis is often unsuspected in children hospitalized with enterovirus infection. The frequency of meningitis among hospitalized infants is serotype dependent and is most frequently, but not exclusively, found with pleocytosis of the cerebrospinal fluid.

Viremia in hospitalized children with enterovirus infections.

In a prospective study during the summer and fall of 1982, enterovirus was isolated from 48 hospitalized children; in 29 (60%) enterovirus was isolated from CSF or blood, and in 19 (40%) only a presumptive diagnosis was established. Blood was positive in 21 (44%) and was the only positive specimen in two children. A presumptive diagnosis was provided within 4 days of admission in 38 (80%) and within 48 hours in 19 (40%) of the children from whom enterovirus was isolated. Viremia was most often detected in febrile infants younger than 3 months of age with a clinical picture simulating bacterial sepsis. The presence of viremia was inversely related to the presence of CSF pleocytosis and to virus isolation from CSF. The diagnosis of diseases caused by enterovirus is more accurate when blood culture is added to CSF stool and throat cultures.

Molecular probes for detection of persisting enterovirus infection of human heart and their prognostic value.

Enteroviruses are well recognized in the aetiology of myocarditis. Molecular hybridization using enterovirus group-specific probes shows that virus can be detected in endomyocardial biopsies and persists in myocardium after the inflammation heals. Virus persistence is associated with the subsequent development of dilated cardiomyopathy, progressing to end-stage disease requiring cardiac transplantation. Infectious virus cannot usually be isolated from myocardium nor can virus-specific antigens be detected after the initial inflammatory stage. Patients with healed myocarditis or dilated cardiomyopathy may have no histological evidence of inflammation despite detection of virus-specific RNA sequences by molecular hybridization. Persisting enterovirus RNA in dilated cardiomyopathy is the strongest known predictor of poor prognosis. The molecular mechanism of virus persistence is the selection of defective virus mutants during the initial phase of disease.
