Plasma concentrations of soluble vascular cell adhesion molecule-1 (sVCAM-1), E-selectin (sE-selectin) and intercellular adhesion molecule-1 (sICAM-1) were measured by enzyme-linked immunosorbent assay in four groups of children. Group 1 consisted of 20 patients with acute diarrhoea-associated haemolytic uraemic syndrome (D+HUS), the aetiology of HUS being verocytotoxin-producing Escherichia coli infection in each case. Controls consisted of 11 patients who had previously had D+HUS (group 2), 12 with chronic renal failure (group 3) and 8 healthy controls (group 4). When compared with healthy controls, the acute D+HUS group had higher sVCAM-1 (median 1,875 ng/ml, range 1,200-6,450 ng/ml vs. 1,200 ng/ml, range 975-2,125 ng/ml), von Willebrand factor antigen, (1.9 U/ml, range 0.85-5.1 U/ml vs. 0.55 U/ml, range 0.3-1.57 U/ml), white cell count (WBC, 14.5 x 10(9)/l, range 7.8-43.1 10(9)/l vs. 8.9 10(9)/l, range 5.7-10.8 10(9)/l) and neutrophil count (PMN, 10.1 x 10(9)/l, range 4.3-26.5 10(9)/l vs. 4.3 10(9)/l, range 3.7-6.6 10(9)/l), all P < 0.005, and sICAM-1 was reduced (230 ng/ml, range 130-340 ng/ml vs. 400 ng/ml, range 260-690 ng/ml), P < 0.05. Within the acute D+HUS group there was a significant correlation between sICAM-1 and PMN (r = 0.56, P < 0.01). There was no correlation between any adhesion molecule and plasma creatinine or von Willebrand factor. Comparing the acute HUS group with children with chronic renal failure, WBC (P < 0.001), PMN (P < 0.01) and sVCAM-1 (P < 0.01) were significantly elevated, but there was no difference between the von Willebrand factor (P = 0.08) or the sICAM-1 (P > 0.1). sVCAM-1 is elevated and sICAM-1 decreased in acute D+HUS. This pattern of altered adhesion molecule concentration is unlike that in adults with vasculitis and suggests that different endothelial regulatory factors are at play.

The aim of the study was to investigate the presence of antibodies to lipopolysaccharides obtained by modified Boivin's method from E. coli serotype O104:H4 and O26, O103, O111, O121, O145, O157 in sera of 7 patients with acute diarrhea, suspected in clinical investigation for infection caused by E. coli O104:H4. Additionally, to determine the cut-off levels, the 75 sera from blood donors were tested. The high level of antibodies to LPS E. coli O104 was diagnosed in three patients from family outbreak caused by E. coli serotype O104:H4. In one of those patients, 7-years boy with HUS, we observed also a significant decrease of level of IgA, IgG and IgM antibodies in serum sample obtained in chronic phase of the disease. Furthermore, we showed that two others patients with clinical evidence of VTEC infection, not connected with this family outbreak, had a high level of antibodies to E. coli of other serotypes: one to O157 and one to O103. We did not observe presence of antibodies to LPS from E. coli O26, O111, O121 i O145 in the sera of tested patients. In conclusion, we confirmed that ELISA based on lipopolysaccharides obtained from different serotypes of E. coli may be helpful in laboratory diagnosis of infection caused by VTEC in humans.

Infectious diarrhea, a common disease of children, deserves permanent monitoring in all social groups. To know the etiology and clinical manifestations of acute diarrhea in children up to 5 years of age from high socioeconomic level households, we conducted a descriptive, microbiological, and clinical study. Stools from 59 children with acute community-acquired diarrhea were examined, and their parents were interviewed concerning symptoms and signs. Rotavirus, adenovirus, and norovirus were detected by commercially available qualitative immunochromatographic lateral flow rapid tests. Salmonella, Campylobacter, Yersinia, and Shigella were investigated by standard bacteriological methods and diarrheagenic E. coli by PCR assays. We identified a potential enteric pathogen in 30 children. The most frequent causes of diarrhea were enteropathogenic E. coli (EPEC), viruses, Campylobacter, Salmonella, and Shiga-toxin-producing E. coli (STEC). Only 2 patients showed mixed infections. Our data suggest that children with viral or Campylobacter diarrhea were taken to the hospital earlier than those infected with EPEC. One child infected with STEC O26 developed "complete" HUS. The microbiological results highlight the importance of zoonotic bacteria such as atypical EPEC, Campylobacter, STEC, and Salmonella as pathogens associated with acute diarrhea in these children. The findings also reinforce our previous communications about the regional importance of non-O157 STEC strains in severe infant food-borne diseases.
