To investigate three possible causes of the acute hemolysis in the hemolytic-uremic syndrome, we studied prospectively 207 children and 34 adults with shigellosis in Bangladesh. Nineteen children showed acute hemolytic anemia, a leukemoid reaction, thrombocytopenia and
oliguria
; nine other had, in addition, a serum urea nitrogen level of over 100 mg per diciliter. Eight of the nine had pseudomembranous colitis, and six of the nine died. The frequency of bacteremia was similar in all grades of shigellosis. Circulating immune complexes were found in 10 of 20 patients with uncomplicated shigellosis and in four of six with severe hemolytic-uremic syndrome. Limulus assay for endotoxemia was positive in nine of 18 patients with hemolysis (50 per cent) and three of 61 with uncomplicated shigellosis (5 per cent) (P less than 0.001). These data support the hypothesis that severe
colitis
in shigellosis is associated with circulating endotoxin from the colon producing coagulopathy, renal microangiopathy and hemolytic anemia.

Escherichia coli O.157:H7 is a serious and common human pathogen that can cause diarrhea, hemorrhagic
colitis
, and the hemolytic uremic syndrome (HUS). During a massive outbreak of infection with E coli O157:H7 in January 1993 in Washington State, more than 600 people, mostly children, acquired symptomatic infection, and 37 were hospitalized with HUS at Children's Hospital and Medical Center in Seattle, and six at other hospitals in Washington. Twenty-one (57%) required dialysis. Nineteen (51%) had significant extrarenal pathology: gastrointestinal in 14 patients (38%), cardiovascular in 13 (35%), pulmonary in 9 (24%), and neurological in 6 (16%). Most patients were managed nonoperatively, but three required total abdominal colectomy and one a left colectomy. No child had perforation. Three patients died, all of whom had multisystem disease. The authors recommend (1) that all patients with bloody diarrhea undergo microbiological evaluation for E coli O157:H7 before any surgical intervention; (2) avoidance of antibiotics and antimotility agents in patients with proven or suspected infection with E coli O157:H7 until the safety and efficacy of such interventions have been established in controlled trials; (3) that patients with E coli O157:H7 infections be evaluated for microangiopathic changes consistent with HUS in the week after onset of diarrhea; (4) nasogastric suction for severe symptoms, and frequent abdominal evaluations, tests (electrolytes/amylase), and roentgenograms to exclude treatable abdominal disorders; and (5) institution of hemodialysis for
oliguria
/anuria, acidosis, or rising creatinine. The authors recommend surgical exploration for toxic megacolon, colonic perforation, acidosis unresponsive to dialysis, or recurrent signs of obstruction or colonic stricture.

We report the case of a 21-year-old man who had been developing acute renal failure with Methicillin-resistant Staphylococcus aureus (MRSA)
colitis
and sepsis. He was admitted for consciousness disturbance, nausea, vomiting, and diarrhea.
Oliguria
was also observed and his serum creatinine level was elevated to 10 mg/dl. Urinary protein was positive and an abundance of hyaline cast were seen in urinary sedimentation. Diarrhea and pyrexia were prolonged and serum C-reactive proteins were elevated, but lymphocyte and leukocyte counts temporarily decreased from the 3rd to the 6th hospital day and remained low until normalizing after the 14th day. His clinical symptoms improved with hemodialysis (HD) and effective antibiotic therapies. An MRSA strain producing toxic shock syndrome toxin-1 (TSST-1), a super antigen which specifically stimulates human V beta 2-positive T cells, was separated from his feces and blood. To ascertain the cause of his renal dysfunction, a renal biopsy was performed on the 8th day. His renal histology revealed acute interstitial nephritis with severe inflammatory cell infiltration around the medullary areas without glomerular changes. Most of the infiltrated cells were small monocytes, and lymphoid cells were rich in the interstitium. With immunohistochemical staining, over 70% of T-cells were V beta 2-positive. TSST-1-producing MRSA was detected in his blood specimen. Furthermore, V beta 2-positive T cells were accumulated in the renal intersititium, and transient lymphocytopenia was observed. These data suggested the following possible pathogenesis for interstitial nephritis: TSST-1 acts as a super antigen in the renal interstitium where major histocompatibility complex (MHC) is class-2-positive, thereby resulting in interstitial nephritis with T cell migration.

The hemolytic-uremic syndrome (HUS) has been recognized for more than 45 years and consists of the combination of hemolytic anemia, thrombocytopenia, and acute renal failure. HUS occurs predominantly in children younger than 4 years of age. It is the most frequent cause of acute renal failure in children. The most common form of the syndrome (D+ HUS) occurs in healthy young children (>6 mo to <5 y of age) and is preceded by watery diarrhea that can evolve to hemorrhagic
colitis
. The diarrhea precedes the hemolysis and thrombocytopenia by 5 to 7 days;
oliguria
/anuria follows several days later. Although the pathogenesis is unknown, available evidence strongly suggests that endothelial cell damage is necessary. The outcome for most patients who have D+ HUS is favorable: 65% to 85% recover completely, 5% to 10% die (usually during the acute illness), recurrence is uncommon, and only a few patients slowly progress to end-stage renal disease (ESRD).

Escherichia coli strains producing Shiga toxins (Stxs) colonize the lower gastrointestinal tract and cause watery diarrhea, hemorrhagic
colitis
, and hemolytic-uremic syndrome (HUS). HUS is characterized by hemolytic anemia, thrombocytopenia, and acute renal failure.
Oliguria
associated with acute tubular necrosis and microangiopathic thrombosis has been reported as the most common cause of renal failure in Argentinean children. Our study was undertaken to obtain a model of HUS in rats that was similar to the clinical and renal histopathology findings described in humans. Rats were intraperitoneally inoculated with culture supernatant from recombinant E. coli expressing Stx2. Glomerular filtrate volume evaluated from clearance of creatinine resulted in a progressive reduction (from 53% at 24 h to 90% at 48 h). Urine volume increased significantly at 24 h but returned to normal levels at 48 h. Evidence of thrombocytopenia, anemia and leukocytosis was documented. Macroscopic analysis revealed a hyperemic peritoneal face with intestinal water accumulation. The kidneys were friable and congestive. Histopathological analysis showed glomerular and tubular necrosis as well as microangiopathic thrombosis. Our findings indicated vascular damage and kidney lesions similar to those described in humans with HUS.

Clostridium difficile colitis, although rare, could represent a serious complication following chemotherapy. Prior antibiotic use has been considered the single most important risk factor in the development of C. difficile infection. Recently, the association between antineoplastic therapy and C. difficile-associated diarrhea in the absence of a prior antibiotic therapy has become more apparent. A 75-year-old woman with serous adenocarcinoma of the ovary developed lethal pancolitis caused by C. difficile after five cycles of paclitaxel- and carboplatin-based chemotherapy. She presented with diarrhea, coffee-ground emesis, and
oliguria
and was hospitalized immediately for aggressive treatment. Despite all the medical efforts, her condition worsened and she died after twenty days. We describe the second case reported of a patient developing a severe C. difficile
colitis
following chemotherapy without any recent antibiotic use and review the data of the literature, emphasizing the need to a prompt diagnosis and management that can significantly decrease the morbidity and life-threatening complications associated with this infection.

It is important to consider that between Jul-October 2009 in the pathologic center of infectious diseases (Tbilisi State Medical University Department of Infectious Diseases) among hospitalized patients with hemorrhagic
colitis
25 patients developed HUS syndrome. Most of patients were rural residents 20 (80%), only 5 (20%) were urban. 11 (44%) patients were children, 14 (56%) were adults. Male and female rate was equal. All the patients related the onset of the disease with the consumption of notwashed raw fruits or vegetables, nonpasteurized dairy products, food from street vendors, soft cheeses made from raw milk and untreated water in areas lacking adequate chlorination. The onset of the disease was not acute: low grade fever (37,5-37,8(0)C), severe diffuse pain in abdomen accompanied with cramps, frequent bowel movement with loose, watery stools 5-6 times a day. On the 2-3rd days of disease condition was worsened by increased of intoxication and frequent bowel movement with bloody stools about 10-15-20 times a day. On the 3-4 rd days of the onset of the diarrhea developed
oliguria
, anuria, edema. Among other complications important were: polyserosit - 8 (32%), encephalopathy - 2 (8%), disseminated intravascular coagulation - 3 (14%), ileus -1 (4%,) acute reactive phsycosis - 1 (4)%. In 15 (60%) cases became necessary to carry out hemodialysis. died 5 patients, lethality is - 5 (20%). Treatment options included: pathogenetic and symptomatic. Thus, increased rate of patients in the recent years indicates to circulation of shiga-toxin producing E.Coli in Georgia.

The aim of the research: identification of etiological structure of acute diarrheas and hemorrhagic
colitis
in Georgia, manifestation of clinical peculiarities and predictors of hemorrhagic
colitis
complicated by HUS ( Hemolytic-Uremic syndrome). In 2011-2013 we studied 274 hospitalized patients at the Center of Infectious Diseases, AIDS and Clinical Immunology (160 hemorrhagic
colitis
and 114 non-bloody diarrhea). Causative agents of hemorrhagic
colitis
(160 patients) were determined in 110 (69%) cases; etiology of the non-bloody diarrhea (114 patients) was established in 46 (40%) cases. Enteronterohaemorrhagic E. coli (EHEC) strains are major causes of hemorrhagic
colitis
. For the confirmation of STEC infection by the bacteriological investigation some significant additional methods were used: serologic examination of feces on shiga- toxin molecular markers by ImmunoCard STAT and PCR methods. Thus, these above mentioned investigations contribute to diagnosis STEC infection at the early stage of the disease. Based on our findings we were able to reveal predictors of complications of hemorrhagic
colitis
by HUS. They include: Delayed hospitalization, rural residents, premorbid background, onset of the disease with low-grade fever accompanied with abdominal cramps, manifestation of bloody diarrhea on the 2-3-rd days of the disease, frequent bowl movement (>20 times a day), development of
oliguria
and edema on the following days, leucocytosis in hemogram, elevation of LDH, creatinine and urea, hypoalbuminemia and development of ascites.

Background Euphorbia granulata is herb of family Euphorbiaceae having several traditional uses. The aim of the study is to summarize reported nutritional and medicinal value along with ethnomedical records. Methods The papers on nutritional and medicinal value of E. granulata are collected from electronic search engines (Google Scholar, PubMed). Synonyms are confirmed from "The plant List." Results Pharmacological studies suggest that the extracts of E. granulata possess antioxidant, antibacterial, antifungal, diuretic, antiulcerative
colitis
and spasmolytic properties. Moreover, it is rich with nutritive components such as carbohydrates, lipid contents (saturated and unsaturated fatty acids), minerals and protein (amino acids). Toxicological data of E. granulata showed that it may be poisonous and toxic at higher doses. Conclusion Research studies suggest that E. granulata has sufficient pharmacological potential against several diseases including infections, gastric ulcers, anuria,
oliguria
and spasmodic disorders; however, more research is required to confirm its pharmacological potential. Moreover, dose fixation studies should be carried out to avoid its toxicity.
