Over 15 years, 14 patients with yersiniosis in two North American comprehensive thalassemia clinics (0.6 cases per 100 patient-years) presented with fever (100%), diarrhea (86%), right-lower-quadrant abdominal pain (71%), bacteremia (57%), a palpable abdominal mass (36%), and pharyngitis (28%). Clinically apparent infection occurred within 10 days of blood transfusion in 57% of patients. Nine patients (64%) had only a modest elevation in serum level of ferritin (< 2,000 micrograms/L). Patients with focal abdominal findings had a higher body iron burden, as estimated by the serum ferritin level, and significant intraabdominal suppurative complications. Two patients were not receiving iron-chelating therapy with deferoxamine; one patient was receiving the experimental chelator deferiprone (L1). Iron-loaded patients with beta-thalassemia are at greatly increased risk for severe yersiniosis, even when their body iron burden (as indicated by the serum ferritin level) is only moderately elevated and they are not receiving iron-chelating therapy with deferoxamine.

A 31/2-year-old girl presented with persistent abdominal pain, fever, vomiting, and diarrhea accompanied by rash, oral ulceration, anemia, and an elevated sedimentation rate. Initial evaluation revealed no pathogens and was extended to include abdominal ultrasound and computed tomography showing marked ileocecal edema and mesenteric adenopathy. Colonoscopy revealed focal ulceration from rectum to cecum with histology of severe active colitis with mild chronic changes. Enteroclysis demonstrated a nodular, edematous terminal ileum. Because of the patient's clinical deterioration despite antibiotics, these features were construed consistent with Crohn's disease, and glucocorticoid therapy was begun. By the ninth hospital day, admission cultures grew Yersinia enterocolitica, and trimethoprim/sulfamethoxazole was begun followed by prompt clinical improvement. The delay in diagnosis afforded an unusually comprehensive clinical description of the presentation and diagnosis of Yersinia enterocolitis in childhood.

Important points during differential diagnosis of ulcerative colitis from other inflammatory disorders are endoscopic examination and microbial studies of stools. In acute phase of enterocolitis in which waterly diarrhea with bloody stool and abdominal pain appeared, infectious enterocolitis by Shigella, Salmonella, Campylobacter and Yersinia, which sometimes causes mucosal edema, hyperemia, erosions and ulceration should be distinguished carefully. Microbial studies of stool would bring helpful information in such situation. In chronic phase of inflammatory diseases of bowel, they often showed chronic diarrhea associated with mucobloody stools and abdominal pain. They often revealed mucosal inflammation mimicking ulcerative colitis during endoscopic evaluation. Among them, most important diseases are amebic colitis, ischemic colitis, radiation colitis and antibiotics associated hemorrhagic colitis.

The high-pathogenicity island (HPI) of Yersinia has been observed in 93% of 60 enteroadhesive Escherichia coli strains and 80% of E. coli strains isolated from blood samples. In the present study we investigated 671 fecal samples from patients with diarrhea in Shandong Province, China, and isolated HPI-harboring E. coli from 6. 26% of the samples. The isolation rates for patients with diarrhea in three age groups, 10 to 20, 30 to 40, and 50 to 60 years, were 6. 70, 12.35, and 10.81%, respectively. Therefore, HPI-harboring E. coli is the third most frequently isolated enteric pathogen from patients with diarrhea. Vomiting and abdominal pain were recorded for 33.33 and 66.67% of the patients, respectively. Stools with blood were observed for 9.52% of the patients. Twenty-four of 42 (57%) patients experienced a temperature over 37.4 degrees C. These observations indicate that HPI-harboring E. coli is one of the major causes of diarrheal disease in China and that the clinical symptoms caused by HPI-harboring E. coli differ from those caused by enteroadhesive E. coli.

A 60-year-old man, although treated with antibiotics, suffered from a severe pyrexial illness of unknown origin, weight loss and intermittent abdominal pain. There was no history of diarrhea or common infections. Computed tomography and ultrasound imaging showed uncharacteristic multiple small lesions of the entire liver parenchyma. These lesions were histologically pyogenic abscesses. In addition, an unexpected, pronounced accumulation of iron pigment in hepatocytes and second degree fibrotic changes of the liver were detected. Serum iron and serum transferrin were low, but serum ferritin concentration and transferrin saturation were increased to the maximum. The demonstration of the cysteine-282-tyrosine mutation confirmed underlying primary hemochromatosis. Bacteriological cultures of the abscess material yielded Yersinia enterocolitica serotype O:3, while stool and blood cultures were negative. Antibiotic therapy with piperacillin/tazobactam and tobramycin was successful within a few days. A repeat CT scan and ultrasound imaging demonstrated complete regression of the pathologic liver morphology. The patient was discharged and treated with an orally administered fluoroquinolone for an additional 6 months. After this time the patient had no morphological residues of the infection except one enlarged lymph node near the portal vein but still was so weak that he was unable to work again. In conclusion, severe septic forms of yersiniosis are mainly found in patients with iron overload, due to a handicapped iron metabolism of the Yersinia bacteria. Mortality is high despite treatment.

A prospective study of 62 chemotherapy-induced neutropenic episodes in patients with acute leukaemia was conducted to determine the incidence and causes of abdominal infections, and to assess the diagnostic value of the combined use of ultrasonography (US) and microbiology. Each patient underwent US of liver, gallbladder and complete bowel before chemotherapy, on days 2-4 after the end of chemotherapy and in cases of fever, diarrhoea or abdominal pain. US was combined with a standardized clinical examination and a broad spectrum of microbiological investigations. From January to August 2001, 243 US examinations were performed. The overall incidence of abdominal infectious diseases was 17.7% (11 out of 62, 95% confidence interval (CI): 9-29%). Four patients (6.5%) developed neutropenic enterocolitis; two of them died, two survived. Bowel wall thickening (BWT) > 4 mm in these four patients ranged from 5.8 to 23.6 mm and was detected only in one patient with mucositis. In three other patients (4.8%) Clostridium difficile, and in one patient (1.6%) Campylobacter jejuni, caused enterocolitis without BWT. Cholecystitis was diagnosed in three patients (4.8%) and hepatic candidiasis was strongly suspected in one patient. Abdominal infections caused by gastroenteritis viruses, cytomegalovirus (CMV) or Cryptosporidium were not observed. We conclude that in neutropenic patients with acute leukaemia receiving chemotherapy: (i) BWT is not a feature of chemotherapy-induced mucositis and should therefore be considered as sign of infectious enterocolitis; (ii) viruses, classic bacterial enteric pathogens (Salmonella, Shigella, Yersinia, Campylobacter, Aeromonas, Vibrio subsp., enterohaemorrhagic Escherichia coli) and Cryptosporidium have a very low incidence; and (iii) abdominal infections may be underestimated when US is not used in every patient with abdominal pain.

Computed tomography (CT) is useful for evaluating the diagnosis of gastrointestinal disease, such as infectious colitis, in patients with severe pain and bloody diarrhea. During the 7 years between November 1993 and October 2000, 34 patients with infectious colitis (18 male, 16 female; mean age 42 +/- 19 yrs), received emergency CT and colonoscopy because of severe abdominal pain and dysentery. The following organisms were isolated: pathogenic Escherichia coli (12), 6 of which were O157:H7 (O-157), Salmonella species (11), Campylobacter species (5), Vibrio parahaemolyticus (3), Yersinia enterocolotica (2) and Shigella species (1). Thickening of the intestinal wall greater than 10 mm was seen in the ascending colon in the 6 cases with E. coli O 157, in 5/11 cases with Salmonella, 4/5 with Campylobacter and 1/6 with non-O157 pathogenic E. Coli. Marked intestinal wall thickening, greater than 20 mm, was seen in the ascending colon of the 4 of the patients with an O-157 infection. In all patients with O-157 colitis, slight ascites was noted in the pelvic space. In additions, ascites was also seen in 3/13 patients with Salmonella and 1/5 patients with Campylobacter colitis. The CT findings, in the patients with infectious colitis, are non-specific but knowledge and recognition of the findings will help in patient evaluation and proper treatment.

Although the literature on infections transmitted via transfused blood focuses on viruses, Yersinia enterocolitica can also cause severe infections in patients receiving transfusions. A 13-year-old patient developed severe sepsis after an autologous blood transfusion contaminated with Y. enterocolitica. The patient was an otherwise healthy female undergoing posterior spinal fusion for congenital scoliosis. Prior to surgery, the patient donated blood for perioperative and postoperative use. A few days before the donation, she had complained of abdominal pain and was experiencing mild diarrhea. The patient received four units of packed red blood cells (PRBCs) during the surgery. Intraoperatively, the patient developed fever up to 103.6 degrees F, became hypotensive requiring epinephrine and dopamine, and developed metabolic acidosis with serum bicarbonate concentration dropping to 16 mmol/l. The surgery team believed the patient was experiencing malignant hyperthermia and attempted to cool patient during the procedure. Postoperatively, the patient was transferred to the pediatric intensive care unit and treated for severe shock of unknown etiology. The patient further developed disseminated intravascular coagulation. The patient received supportive care and was started on ampicillin/sulbactam on postoperative day (POD) one which was changed to clindamycin, ciprofloxacin and tobramycin on POD two when blood cultures grew gram-negative bacilli. On POD three, cultures were identified as Y. enterocolitica and antibiotics were changed to tobramycin and cefotaxime based on susceptibility data. Sequelae of the shock included adult respiratory distress syndrome requiring intubation and a tracheostomy and multiple intracranial hemorrhagic infarcts with subsequent seizure disorder. Due to severe lower extremity ischemia, she required a bilateral below the knee amputation. The cultures of the snippets from the bags of blood transfused to the patient also grew Y. enterocolitica. This case illustrates the importance of considering transfusion related bacterial infections in patients receiving PRBCs. All patients in shock following any type of transfusion may require aggressive antibiotic therapy, until the diagnosis and etiology are known.

Bacterial diarrhea can be classified into two clinical entities, noninflammatory diarrhea and inflammatory diarrhea syndromes. The latter type of diarrhea is characterized by bloody and puruloid mucus stool, and is often accompanied by fever, tenesmus, and severe abdominal pain. Pathogenic bacteria causing the inflammatory diarrhea syndrome include Salmonella, Vibrio, Shigella, enteroinvasive and enterohemorrhagic Escherichia coli, Campylobacter, Yersinia, Chlamydia, and Clostridium difficile. The pathologic changes in the inflammatory diarrhea syndrome range from a superficial exudative enterocolitis to a transmural enterocolitis with overt ulceration. This syndrome is also designated as bacterial hemorrhagic enterocolitis because of its usual manifestation by bloody diarrhea. The diagnostic approach needs information on the patient's age, travel history, epidemiological associations, sexual practice, and medical history, including usage of antibiotics. Bacterial information can be obtained by microscopic study, culture, and the identification of specific bacterial toxins. Flexible colonoscopy with biopsy is useful for the differentiation of bacterial hemorrhagic enterocolitis from idiopathic ulcerative colitis and ischemic colitis. Physicians should be familiar with the diagnostic modalities used to detect the specific pathogens causing hemorrhagic bacterial enterocolitis; namely, bacterial culture, serology, histology, and nucleic acid technologies.

Human infections due to Yersinia enterocolitica have been reported worldwide, predominantly in Europe. However, there have been few reports of Yersinia enterocolitica infection in Taiwan. We report a case of Y. enterocolitica sepsis in a 15-year-old Taiwanese girl with Cooley's anemia and insulin-dependent diabetes mellitus. She presented at admission with fever, shock and consciousness disturbance. She had symptoms of abdominal pain, vomiting and diarrhea for three days before admission. Blood pressure stabilized after intravenous normal saline rescue. Blood culture yielded Y. enterocolitica 2 days later and ceftriaxone was administered according to the results of sensitivity tests. She recovered well after a course of antibiotic treatment. Though Y. enterocolitica sepsis is rare in Taiwan, clinicians should be aware of its tendency to develop in patients with Cooley's anemia, fever and enterocolitis and that its clinical course may include sepsis leading to shock.
