Hemolytic uremic syndrome (HUS) consists of an acute onset of microangiopathic hemolytic anemia, thrombocytopenia, and renal dysfunction. HUS-associated colitis can be seen in up to 100% of patients and is usually associated with severe abdominal pain and distention. Colonic perforation is a complication of HUS that has a reported incidence of 1%-2%, and although there are several case reports in the literature describing perforation of the colon, it is still very difficult to discern the abdominal symptoms associated with HUS colitis from perforation. Four cases of colonic perforation are reported here from a consecutive series of 57 patients, in which a trend in the length of time from the onset of symptoms of HUS to colonic perforation was determined. A review of the literature for cases of HUS-associated colonic perforation was also performed. The time from the onset of HUS symptoms to colonic perforation in our series was similar to that found in the literature review (11 +/- 5 vs 14 +/- 8 days). Awareness that this complication has a tendency to occur towards the end of the 2nd week during the course of HUS is essential to avoid an unnecessary and untimely surgical intervention.

Predictive factors for the development of hemolytic uremic syndrome (HUS) were evaluated in 88 inpatients who suffered from enterohemorrhagic E. coli infections in the outbreak in Sakai, 1996. All in- and outpatients received oral or intravenous fosfomycin within acute phase of hemorrhagic colitis, and HUS complicated 1.4% of them. Persistence of bloody stools and diarrhea were longer in HUS patients than in non-HUS patients, but persistence of abdominal pain was not different in either group. Leukocytosis with leukocyte counts over 15,000/microliters and/or elevated CRP level over 2.0 mg/dl at admission, and fever and/or vomiting in the course of hemorrhagic colitis were more frequent in HUS patients than in non-HUS patients. Early intensive treatments including gammaglobulin, urinastatin, aspirin, and dipyridamole were employed in 34 high risk patients for prevention of HUS. These patients were estimated to be at risk of developing HUS because of incomplete HUS, nephropathy, elevated LDH level, thrombocytopenia, or age younger than two years old. These treatments were clinically effective.

We encountered a patient with enterohemorrhagic Escherichia coli (EHEC) O157:H7 infection and secondary hemolytic uremic syndrome (HUS). The patient was a 79-year-old woman with hypertension, constipation, and asymptomatic cholelithiasis. She complained of nausea and abdominal pain, and had bloody stool EHEC O157 was detected by fecal culture. The bloody stool resolved after treatment with antibiotics, but the patient was hospitalized on July 23, 1996 because of abdominal distention. HUS was diagnosed because of proteinuria, hematuria, thrombocytopenia, hemolytic anemia, fragmentation of red blood cells, and increased serum LDH. Treatment was focused on plasma exchange, administration of antibiotics, large doses of gamma-globulin, haptoglobin replacement, and anticoagulation. Within about 2 weeks, the level of hemoglobin, the number of platelets, and the serum LDH had normalized, and the patient recovered from HUS. The decreased intestinal movement continued. On August 23, acute cholecystitis was diagnosed, and percutaneous transhepatic gall bladder drainage was done. Another exacerbation was noted on October 13, and cholecystectomy was done on November 12, when the patient's status had improved after instillation of antibiotics. Macroscopically, the gallbladder wall was thickened. Histopathological examination showed diffuse infiltration of lymphocytes into the mucosa, chronic cholecystitis was diagnosed. Because the postoperative course was satisfactory, the patient was discharged from the hospital on December 15. Acute exacerbation of chronic cholecystitis might have been caused by decreased cholic excretion after the marked decrease in intestinal movement due to O157 infection and secondary HUS. Because elderly people frequently have anamnesis of the digestive system, considerably attention should be paid to the management of anamnesis, as well as O157 infection and secondary HUS.

Verotoxin-producing Escherichia coli (VTEC) O157:H7 is a major cause of hemorrhagic colitis that is often associated with the development of hemolytic uremic syndrome (HUS). In July, 1996, a severe mass outbreak of VTEC O157 infection occurred in Sakai city, Osaka. The present study investigates the risk factors which may contribute to the development of HUS in the early stages of the VTEC O157 infection. There was no significant difference between HUS-developed and non-HUS-developed groups with respect to sex, age, rates of clinical manifestations, such as fever, abdominal pain and bloody stool, use of anti-diarrheal agents, anti-motility agents, and/or antibiotic agents, and serum sodium concentrations at the early stage of VTEC O157 infection. Thus, these factors did not appear to be risk factors associated with the development of HUS. In contrast, leukocyte counts and C-reactive protein levels in the early stage of VTEC O157 infection were significantly higher in the HUS-developed group (P < 0.001), suggesting that these are risk factors associated with the development of HUS.

We report a case of a nine-year old boy with vomiting, abdominal pain and fever, who underwent surgery with a diagnosis of appendicitis in Mendoza and from whom a Shiga toxin-producing Escherichia coli (STEC) O127:H21 strain was recovered. Forty-eight hours after surgery he presented bilious vomiting and two episodes of intestinal bleeding. Laboratory findings included: hematocrit, 35%; blood urea nitrogen, 0.22 g/L. The urinary output was normal. The following day physical examination showed an alert mildly hydrated child, without fever but with distended and painful abdomen. The patient was again submitted to surgery with a diagnosis of intestinal occlusion. Bleeding and multiple adhesions in jejunum and ileum were found. The patient still had tense and painful abdomen and presented two bowel movements with blood; hematocrit fell to 29% and blood urea nitrogen rose to 0.32 g/L. STEC O127:H21 eae(-)/Stx2/Stx2vh-b(+)/E-Hly(+) was isolated from a stool sample. He was discharged after 10 days of hospitalization and no long-term complications such as HUS or TTP were observed. This is the first report, to our knowledge, on the isolation of E. coli O127:H21, carrying the virulence factors that characterize STEC strains, associated to an enterohemorrhagic colitis case. This serotype was previously characterized as a non-classic enteropathogenic E. coli (EPEC). STEC infections can mimic infectious or noninfectious pathologies. Therefore an important aspect of clinical management is making the diagnosis using different criteria thereby avoiding misdiagnoses which have occasionally led to invasive diagnostic and therapeutic procedures or the inappropriate use of antibiotics.

We report on 4 cancer patients with transient unspecific elevations of the serum tumor markers CA 19-9, CEA, CA 125 and CA 72-4, respectively. In one patient cholangitis due to biliary obstruction induced a significant transient increase of CA 19-9, in another patient HUS, probably as a severe complication after Mitomycin-C + Gemcitabine therapy resulted in a significant increase of serum CA 125. One patient demonstrated an extensively elevated and inexplicable serum CA 19-9 concentration (9450 u/ml) during a period of abdominal pain with continuous decrease and finally normalization within the following 5 years. Also inexplicable is an unexpected remittent increase of serum CA 72-4 in the course of chemotherapy after gastrectomy for gastric carcinoma. The presented data underline the necessity of interpreting serum courses of tumor markers only in the light of all available clinical data, imaging data and other laboratory tests in order to avoid misinterpretations.

The Shiga-toxin-producing E. coli represent a major class of pathogens that have been defined over the last twenty years. They cause distinctive clinical manifestations such as afebrile bloody diarrhea with severe abdominal pain (hemorrhagic colitis) and microangiopathic hemolytic anemia with renal failure (hemolytic uremic syndrome). The most common Shiga-toxin-producing E. coli is serotype O157:H7, although at least one hundred different serotypes share the virulence traits and clinical manifestations with this organism. Understanding the pathophysicology, improving diagnostic tools, and developing a treatment strategy are important areas of ongoing investigations.

Shiga toxin producing E. coli (STEC) may cause severe hemorrhagic colitis followed by hemolytic uremic syndrome (HUS). In Korea, there had been a few case reports of HUS by STEC, mostly due to O157 serotype. The reports of HUS caused by STEC non-O157 serotype were rare. We report a sporadic case of HUS associated with hemorrhagic colitis. A 51-year-old woman was admitted to our hospital due to intractable abdominal pain and bloody diarrhea. Three days after admission, azotemia and microangiopathic hemolysis developed. E. coli, serotype O111 was identified. Conservative management with plasmapheresis resulted in a complete recovery.

Various hematological abnormalities including fall in serial values of hemoglobin or hematocrit, coagulation factor abnormalities, leukocytosis, acute hemolytic anemia, thrombocytopenia, and thrombotic thrombocytopenic purpura or hemolytic uremic syndrome have been reported in patients with acute pancreatitis. Similarly, abnormalities of blood coagulation factors consistent with disseminated intravascular coagulopathy (DIC) have also been noticed in patients with pancreatitis. We report a case of a 33-year-old female with acute pancreatitis who presented with one episode of epistaxis and abnormal prothrombin time and partial prothrombin time. Coagulation work-up revealed thrombin time 24.3 s fibrinogen 110 mg/dl, D-dimers >1 and < 2, and fibrin degradation products >22. Pancultures did not show any evidence of infection. The patient maintained a normal renal and mental status during her illness. Her D-dimers continued to decrease with resolution of acute pancreatitis as evidenced by decreased abdominal pain, relief of nausea, control of vomiting, and decrease in serum amylase and lipase levels. This case report suggests that coagulation abnormalities are encountered in patients with acute pancreatitis. It is hypothesized that such hemostatic abnormalities may be related to early intravascular consumption of coagulation factors secondary to circulating pancreatic enzymes, particularly trypsin, or secondary to vascular injury. Recognition of these hematological complications including DIC is paramount. Physicians caring for these patients should be aware of such a complication of acute pancreatitis.

An 11-year-old girl presented to a central California children's hospital with a 3-day history of erythematous lesions on her forehead, neck, and trunk, abdominal pain, persistent emesis, and decreased urinary output. One day prior to admission she had a mild bout of diarrhea with a small amount of blood in her stool. Upon admission her condition rapidly worsened with acute renal failure, anemia, and thrombocytopenia. One of the possible causes of this condition included hemolytic uremic syndrome. Stool cultures of this patient tested at the children's hospital and at a state reference laboratory were repeatedly negative for Escherichia coli O157:H7. However, the state reference laboratory detected a toxigenic strain of Hafnia alvei active on Vero cells from two consecutive stool cultures during the acute phase of her illness.
