Hirschsprung's disease. Identification of risk factors for enterocolitis.

From 1975 to 1985, 80 infants and children were treated at a major pediatric hospital for Hirschsprung's disease, 19 (24%) of whom developed enterocolitis. In 9 neonates (18%) and 4 infants (29%) enterocolitis was present at diagnosis of Hirschsprung's disease, while 4 children acquired enterocolitis following a pull-through procedure. Significant risk factors for development of Hirschsprung's-associated enterocolitis (HAEC) were delay in diagnosis beyond 1 week of age and the presence of trisomy 21. HAEC did not occur more frequently in patients with long-segment aganglionosis, nor did an initial episode of HAEC confer a higher risk of recurrent enterocolitis. HAEC following a pull-through procedure was correlated with an anorectal stricture in three of four cases. Although neonates with HAEC had a low mortality rate (5%), their morbidity rate was 30% and their hospitalization was twice as long as neonates without enterocolitis.

Increased incidence of necrotizing enterocolitis in premature infants born to HIV-positive mothers.

OBJECTIVE: To examine if being born to an HIV-positive mother may increase the risk of necrotizing enterocolitis in premature infants. DESIGN: Case-control study. SETTING: Neonatal unit of a level 3 perinatal centre. METHODS: : Over a period of 8.5 years, all cases of necrotizing enterocolitis occurring in premature infants admitted to the neonatal unit were identified. For each case, two controls were retrospectively chosen that matched for postmenstrual age at birth, intrauterine growth and year of birth. Perinatal characteristics were studied in all infants. MAIN RESULTS: There were 79 cases of necrotizing enterocolitis, which were compared with 158 controls. Using multivariate analysis, multiple pregnancy [odds ratio (OR), 2.29; 95% confidence interval (CI), 1.23-4.25; P = 0.009], abnormal umbilical artery velocity (OR, 2.21; 95% CI, 1.08-4.54; P = 0.030), abnormal fetal heart rate (OR, 2.14; 95% CI, 1.05-4.36; P = 0.036) and HIV-positive mother (OR, 6.63; 95% CI, 1.26-34.8; P = 0.025) were significantly more frequent in fetuses who subsequently developed necrotizing enterocolitis. CONCLUSIONS: This preliminary report suggests an association, not previously reported, between maternal HIV-positive status and an increased risk of necrotizing enterocolitis in premature infants. Despite the limitations of this study, we suggest that premature newborn infants of HIV-positive mothers should be monitored very carefully for a possible increased risk of necrotizing enterocolitis.

The prognostic value of a risk score for necrotising enterocolitis.

Necrotising enterocolitis is the most common severe acquired gastrointestinal disorder in the neonate yet there remains disagreement on predictive and prognostic factors. A previously published risk score purports to predict infants at greater risk of the disease. Fifty-nine cases and 59 matched controls were evaluated using data from the first 24 h after birth to determine the predictive and prognostic value of the score for necrotising enterocolitis. In simple models the risk score was significantly, but inversely, associated with necrotising enterocolitis, primarily due to greater respiratory problems among controls. This finding contrary to the premise is clarified by a significant interaction of the risk score with feeding variables. Odds ratios for the risk score varied at different levels of daily feeding increments. However, the risk score was not statistically significant in any models which controlled for feeding increment and the interaction. The risk score was significantly associated with mortality among necrotising enterocolitis cases. Though the score was not statistically significant when the outcome was disease stage or surgery, trends were in the expected direction. The data suggest that the risk score itself may not be an independent predictor of necrotising enterocolitis, but may indicate infants more vulnerable to other potential risk factors and, in addition, may be related to prognosis for those who do develop necrotising enterocolitis.

Perinatal risk factors for necrotizing enterocolitis.

The perinatal histories of 50 very low birthweight infants weighing 1500 g, or less, with necrotizing enterocolitis were compared with those of the remaining 325 very low birthweight infants who were admitted to this hospital during a four year study period. Many factors previously reported to be associated with necrotizing enterocolitis were found with equal frequency in both groups of babies. The only adverse factor which was more frequently present in patients with necrotizing enterocolitis was hypothermia on admission to hospital. Those infants who developed severe necrotizing enterocolitis also had a higher incidence of polycythaemia. A further controlled study which examined feeding practices showed that the timing, type, and volume of milk feeding were not different in infants with necrotizing enterocolitis and matched controls. Prematurity is clearly the greatest risk factor which predisposes to the development of necrotizing enterocolitis and most of the factors previously implicated in the aetiology may simply represent the descriptive characteristics of a population of sick, very low birthweight infants.

Doppler flow velocimetry in the superior mesenteric artery on the first day of life in preterm infants and the risk of neonatal necrotizing enterocolitis.

OBJECTIVE: The purpose of this work was to relate Doppler indices of splanchnic perfusion and vascular resistance to the risk of developing necrotizing enterocolitis. METHODS: We conducted a prospective cohort study with analysis of Doppler flow velocity waveforms of splanchnic vessels on the first day of life. Clinical management and diagnosis of necrotizing enterocolitis were performed blind to the Doppler results in a tertiary NICU on 64 eligible preterm neonates admitted for intensive care. We measured necrotizing enterocolitis using an objective diagnostic classification. RESULTS: When adjusted for gestational age at birth, the following indices of the Doppler flow velocity wave form in the superior mesenteric artery were significantly predictive of the risk of necrotizing enterocolitis: end-diastolic velocity, mean velocity, and pulsatility index. The association between necrotizing enterocolitis and Doppler velocimetry indicative of high vascular resistance was independent of a range of other factors and comorbidities (race, mode of delivery, umbilical arterial catheter, growth restriction, patent ductus arteriosus, jaundice, respiratory distress syndrome, mechanical ventilation, and hypotension). CONCLUSIONS: We concluded that neonates with high resistance patterns of blood flow velocity in the superior mesenteric artery on the first day of life are at increased risk of developing necrotizing enterocolitis.

Comparison of serum parathyroid hormone and ionized calcium and magnesium concentrations and fractional urinary clearance of calcium and phosphorus in healthy horses and horses with enterocolitis.

OBJECTIVE: To evaluate calcium balance and parathyroid gland function in healthy horses and horses with enterocolitis and compare results of an immunochemiluminometric assay (ICMA) with those of an immunoradiometric assay (IRMA) for determination of serum intact parathyroid hormone (PTH) concentrations in horses. ANIMALS: 64 horses with enterocolitis and 62 healthy horses. PROCEDURES: Blood and urine samples were collected for determination of serum total calcium, ionized calcium (Ca2+) and magnesium (Mg2+), phosphorus, BUN, total protein, creatinine, albumin, and PTH concentrations, venous blood gases, and fractional urinary clearance of calcium (FCa) and phosphorus (FP). Serum concentrations of PTH were measured in 40 horses by use of both the IRMA and ICMA. RESULTS: Most (48/64; 75%) horses with enterocolitis had decreased serum total calcium, Ca2+, and Mg2+ concentrations and increased phosphorus concentrations, compared with healthy horses. Serum PTH concentration was increased in most (36/51; 70.6%) horses with hypocalcemia. In addition, FCa was significantly decreased and FP significantly increased in horses with enterocolitis, compared with healthy horses. Results of ICMA were in agreement with results of IRMA. CONCLUSIONS AND CLINICAL RELEVANCE: Enterocolitis in horses is often associated with hypocalcemia; 79.7% of affected horses had ionized hypocalcemia. Because FCa was low, it is unlikely that renal calcium loss was the cause of hypocalcemia. Serum PTH concentrations varied in horses with enterocolitis and concomitant hypocalcemia. However, we believe low PTH concentration in some hypocalcemic horses may be the result of impaired parathyroid gland function.

Does exposure to magnesium sulfate in utero decrease the risk of necrotizing enterocolitis in premature infants?

BACKGROUND: The objective of this study is to assess whether antenatal exposure to magnesium sulfate may decrease the risk of necrotizing enterocolitis in preterm infants. METHODS: We have compared the rate of magnesium sulfate exposure before birth among 23 consecutive infants diagnosed with necrotizing enterocolitis with that of 46 controls matched by gestational age at delivery and gender. Relevant obstetric and neonatal variables were compared between the two groups using chi-square and Fisher's exact test for categorical data, and one-way analysis of variance for continuous variables, with a two-tailed p-value <0.05 considered significant. RESULTS: No significant differences were present between the two groups in mode of delivery (p=0.9), rate of Apgar score at five minutes below seven (p=0.4), prenatal exposure to indocin (p=0.5) or steroids (p=0.6), or neonatal administration of surfactant (p=0.1). Similar proportions of babies with necrotizing enterocolitis and controls were diagnosed with respiratory distress syndrome (p=0.5), intraventricular hemorrhage grades three or four (p=0.9), and sepsis (p=0.6). Babies with necrotizing enterocolitis had a significantly longer hospital stay (74.6+/-64.0 vs. 41.9+/-37.0 days, p=0.01) and intubation period (31.4+/-24.1 vs. 16.8+/-15.6 days, p=0.01) than controls. The rates of prenatal exposure to magnesium sulfate were similar in the necrotizing enterocolitis and control groups (30% vs. 39% respectively, p=0.4). Power analysis demonstrated that 385 babies would be required in each group to reach statistical significance (alpha=0.05, beta=80%). CONCLUSION: In this retrospective case-control study, maternal administration of magnesium sulfate prior to delivery does not appear to confer a significant protective effect for the neonatal occurrence of necrotizing enterocolitis.

[Factors associated with necrotizing enterocolitis].

OBJECTIVE: To evaluate the features of clinical presentation of neonatal necrotizing enterocolitis and its associated factors. METHODS: Retrospective study of the cases of neonatal necrotizing enterocolitis (n = 56) diagnosed at Neonatal Intensive Care Unit Lagoa (NICU), between December 1986 and July 1992. Diagnosis and stages of the disease followed the modified Bell's criteria. Diagnosis and follow-up of all cases were evaluated. The cases of enterocolitis - degrees II and III (n = 44) - were subsequently selected and compared to a case-control group (n = 44), selected according to birthweight (+/- 250 g) and hospitalization period (+/- 2 weeks). The statistically significant analysis was considered as p < 0.05. RESULTS: Out of 2,447 newborns admitted to the NICU, 56 (2.3%) presented enterocolitis. Mean weight was 1908.5 g; mean gestational age was 35 weeks and 1 day; mean period for diagnosis was 10.7 days; 51 (91.1%) patients were fed before diagnosis; 18 (32.1%) needed urgent surgery; nine (16.9%) hemocultures were positive; 10 (17.8%) patients died. Four clinical standards were observed: fulminant, acute with pneumatosis, insidious and suspect. Comparatively to the case-control group, three factors were significantly associated with enterocolitis: apnea (p = 0.045), rapid increase of food intake (< 20 ml/kg/day) - (p = 0.048) and presence of infectious agent (p = 0.000). CONCLUSIONS: Significant factors associated with enterocolitis were occurrence of apnea, rapid increase of food intake and identification of the infectious agent.

Bacteremia in infants with Salmonella enterocolitis.

In order to determine the incidence of Salmonella bacteremia in children with Salmonella enterocolitis and to predict the risk factors of bacteremia, we conducted a prospective study on 264 infants and children with Salmonella enterocolitis from January 1, 1988 to December 31, 1989. They were admitted to the Pediatric Department of Mackay Memorial Hospital with the chief problem of diarrhea. The rectal swab cultures were all positive for nontyphoidal Salmonella. Blood cultures were done immediately when Salmonella enterocolitis was confirmed. Clinical features including age, clinical symptoms, laboratory data, and serogroup were all recorded and analyzed to predict the risk factors of bacteremia in Salmonella enterocolitis. Twenty patients had bacteremia. Among them, 4 had meningitis simultaneously. There was one death, resulting in a 5% mortality in the bacteremia group. The overall rate of bacteremia was 7.6%. For those less than 3 months of age, it was 11.5%. We were unable to find any relationship between the bacteremia and the risk factors such as age, body temperature, clinical symptoms, white blood cell counts and differential counts. Interestingly, it was noted that Salmonella serogroup D1, a highly virulent and invasive Salmonella serogroup, was more closely related to the occurrence of bacteremia. It accounted for 40% of all cases of bacteremia. In conclusion, this study showed that the incidence of bacteremia in cases of Salmonella enterocolitis was 7.6% and the only risk factor of bacteremia was a culture of Salmonella serogroup D1. Therefore, in cases of Salmonella serogroup D1 enterocolitis, antibiotics treatment may be considerable.

Effect of necrotizing enterocolitis on urinary epidermal growth factor levels.

The pattern of urinary epidermal growth factor/creatinine levels in necrotizing enterocolitis was examined in 75 infants (in 28 infants the diagnosis of necrotizing enterocolitis was considered; 47 infants were studied for effect of surgery or nutrition on epidermal growth factor levels). There was a consistent and significant increase in epidermal growth factor/creatinine values at the time of diagnosis of necrotizing enterocolitis compared with baseline values. Epidermal growth factor levels in infants without necrotizing enterocolitis and in early nutrition remained unchanged. These results suggested that urinary epidermal growth factor/creatinine levels may differentiate stage II and III necrotizing enterocolitis from stage I disease. The increased epidermal growth factor/creatinine levels may be related to the absorption into the circulation of preexisting gastrointestinal tract epidermal growth factor through damaged tissue or to increased synthesis by the gastrointestinal tract in response to the injury caused by necrotizing enterocolitis.

[Clinico-pathological re-examination on the first diagnosis as enterocolitis unclassified].

Sixteen surgical resected cases of "enterocolitis unclassified" diagnosed on the first pathological examination were re-examined. Their incidence was 3.0% of non-neoplastic bowel diseases registered in our department. On the re-examination including additional microscopic sections, histological reconstruction, special stainings and precise clinical data of each lesion, the 16 lesions were macroscopically divided to nine types and re-diagnosed as follows: (1) definite diseases: ulcerative colitis and phlegmonous enterocolitis, (2) probable diseases: intestinal tuberculosis and infective enterocolitis, (3) possible diseases: healed ischemic colitis, healed ischemic enteritis, healed infective colitis, and healed Crohn's disease or healed ulcerative colitis, (4) enterocolitis unclassified in a narrow sense. In conclusion, patho-morphologically the 16 lesions of enterocolitis unclassified might be subdivided into 13 lesions with the similarity to the already known inflammatory bowel diseases and three lesions with enterocolitis unclassified in a narrow sense.

High morbidity of enterostomy and its closure in premature infants with necrotizing enterocolitis.

OBJECTIVE: To review the morbidity and mortality among 68 premature infants treated with enterostomy for necrotizing enterocolitis. DESIGN: Data were collected retrospectively from hospital medical records to include the period between January 1, 1987, and September 30, 1997. SETTING: Tertiary care children's hospital. PATIENTS: A group of 68 infants aged 2 to 35 days (mean age, 12.5 days), weighing 1500 g or less, with necrotizing enterocolitis necessitating surgical enterostomy for treatment. INTERVENTIONS: Creation of any enterostomy during exploratory laparotomy for necrotizing enterocolitis and subsequent closure. MAIN OUTCOME MEASURES: Morbidity and mortality associated with infant enterostomy and its closure. RESULTS: Thirty-nine infants underwent ileostomy with mucous fistula, 16 underwent ileostomy with a Hartmann pouch, 7 had jejunostomy with mucous fistula, 2 had colostomy with mucous fistula, and 4 had colostomy with a Hartmann pouch. Eighteen (26%) of the 68 infants died in the postoperative period of sepsis (n = 10), continuing necrotizing enterocolitis (n = 5), or respiratory distress (n = 3). Of the remaining 50 infants, complications developed in 34 (68%). These complications included strictures requiring further resection at the time of enterostomy closure in 20 infants; stricture of the enterostomy requiring surgical revision in 6; incisional hernia in 3; parastomal hernia in 4; enterostomal prolapse or intussusception in 6 and 1, respectively; wound dehiscence in 4; wound infection in 8; small-bowel obstruction requiring laparotomy in 2; and anastomotic complications in 2. Only 16 enterostomies were closed uneventfully, with 3 of these infants subsequently dying of sudden infant death syndrome between 6 and 8 months after the operation. Of the surviving infants, 3 (6%) continue to require home hyperalimentation. CONCLUSIONS: Although enterostomy in infants with low birth weight with necrotizing enterocolitis may be lifesaving, it is also a major cause of morbidity. These data suggest the feasibility of a prospective study comparing resection and primary anastomosis with resection and enterostomy.

Surgical treatment of cytomegalovirus enterocolitis in severe human immunodeficiency virus infection. Report of eight cases.

PURPOSE: The aim of this study was to describe our experiences of surgical removal of inflamed bowel in cytomegalovirus enterocolitis. METHODS: Eight homosexual males with a mean age of 41 years (range, 29-59 years) and a mean CD4 count of 21 x 10(6)/l (1-60 x 10(6)/l) with advanced human immunodeficiency virus infection and severe cytomegalovirus enterocolitis were treated with ileocecal resection (4 patients) or right-sided hemicolectomy (4 patients). Symptoms were lower abdominal pain, severe diarrhea, fever, and weight loss, unrelieved by anticytomegalovirus therapy. Radiologic examination showed that ulcerative inflammation was limited to the right colon and terminal ileum. Microscopic examination confirmed the cytomegalovirus enterocolitis. Intermittent cytomegalovirus treatment, usually with foscarnet for 10 to 14 days every 4 to 6 weeks was given postoperatively. RESULTS: Two minor postoperative complications occurred: a lesser wound infection and a moderate bleeding from the abdominal wound edges. One patient died after three weeks because of gastrointestinal bleeding from an ulcerating Kaposi's sarcoma lesion and another patient died from unrelated causes three weeks after discharge from the hospital. The remaining 6 patients experienced complete or partial palliation of the abdominal symptoms for a mean of 14 months (range, 5-35 months) until death or the end of observation time. One patient is still alive two years after the operation. The overall mean survival was 12 months (range, 0.5-35 months). Recurrent or persistent symptoms and/or signs of cytomegalovirus enterocolitis occurred in four patients after a mean of seven months. CONCLUSION: Resection of inflamed bowel combined with postoperative anticytomegalovirus treatment leads to excellent palliation and a relatively favorable survival in AIDS patients with cytomegalovirus enterocolitis.

Bacterial hemorrhagic enterocolitis.

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.

Neutropenic enterocolitis in adults: case series and review of the literature.

Necrotizing enterocolitis in adults is a rare disease and, in the past, has been associated with nearly uniform mortality. In recent years, necrotizing enterocolitis, now termed neutropenic enterocolitis, in adults has become more prevalent as a complication of aggressive systemic chemotherapy. In this report, we discuss two cases of neutropenic enterocolitis secondary to the administration of systemic chemotherapy in adult cancer patients: one with lung carcinoma, the other with leukemia. Both patients were successfully treated with early surgical intervention for resection of all necrotizing enteric lesions, and subsequent aggressive critical care support. Our experience suggests that early surgical intervention in adult patients with intestinal necrosis due to chemotherapy is essential to avoid mortality from this condition. Given the widespread, aggressive use of systemic chemotherapy in the neoadjuvant setting, patients at risk for this potentially lethal complication of neutropenic enterocolitis are increasingly common.

Neonatal necrotizing enterocolitis. A 10 year experience.

Neonatal necrotizing enterocolitis was seen in 42 of 5,030 infants (0.83 percent) admitted to our neonatal intensive care units. The condition developed more than 1 week after birth in most infants. This group included most of the very low birth weight infants. Forty-one of the 42 infants had enteral feedings before the onset of enterocolitis, which developed within 72 hours from the start of feedings in 19 infants (45 percent). Twenty-nine patients (69 percent) underwent surgery. Mortality in this group was 38 percent overall and 28 percent in the infants considered salvageable at laparotomy. The interval from diagnosis to surgery was 24 hours or less in 65 percent of cases, emphasizing the fulminant nature of the disease in many patients. Three of the 14 patients who died underwent no surgery. Pneumoperitoneum was one of the initial radiologic signs in 10 patients (24 percent). The necrotizing enterocolitis observed was similar clinically to that reported by others. The strikingly low incidence of enterocolitis in the neonatal intensive care units in Oregon (0.83 percent) contrasts with the generally reported incidence of 3 to 8 percent in other neonatal intensive care units. We attribute the low incidence of necrotizing enterocolitis in our experience to delay of enteral feedings and reliance on prolonged peripheral or central total parenteral nutrition, or both, for nutritional maintenance of stressed or low birth weight infants.

Tissue interleukin 1 and interleukin-1 receptor antagonist expression in enterocolitis in resistant and susceptible rats.

BACKGROUND/AIMS: Subserosal injection of purified group A streptococcal peptidoglycan-polysaccharide (PG-APS) induces chronic relapsing granulomatous enterocolitis and systemic inflammation in susceptible inbred Lewis rats but only transient intestinal injury in Buffalo and Fischer rats. Cecal interleukin 1 (IL-1) and IL-1 receptor antagonist (IL-1ra) expression was measured in inbred rats displaying differential susceptibility to experimental enterocolitis. METHODS: The ileum and cecum of Lewis, Buffalo, and Fischer rats were subserosally injected with purified PG-APS or albumin. IL-1 and IL-1ra messenger RNA (mRNA) and protein (IL-1 only) were measured 1 or 27 days later. PG-APS-injected Lewis rats were treated with recombinant human IL-1ra. Kinetics of IL-1 and IL-1ra mRNA expression were studied in peritoneal cells. RESULTS: All rats strains developed acute inflammation with increased cecal concentrations of IL-1 beta and IL-1ra mRNA. Lewis rats developed chronic enterocolitis and had higher IL-1 and IL-1ra mRNA tissue levels than Buffalo or Fischer rats, which displayed no chronic inflammation. IL-1 beta and IL-1ra were produced by submucosal granulomas and correlated with inflammation. IL-1 alpha protein levels paralleled IL-1 beta mRNA expression. IL-1ra treatment attenuated acute and chronic enterocolitis, adhesions, and arthritis. PG-APS induced IL-1 and IL-1ra expression in peritoneal cells from Lewis and Fischer rats. CONCLUSIONS: Bacterial cell wall polymers stimulate IL-1 and IL-1ra expression in vivo and in vitro. These counterbalancing cytokines are increased in experimental enterocolitis and have important immunoregulatory roles in intestinal inflammation.

ED presentation of neutropenic enterocolitis in adult patients with acute leukemia.

The purpose of this study was to investigate the initial clinical features and subsequent outcomes in patients with adult leukemia with typhlitis or neutropenic enterocolitis. A retrospective review of 10 episodes of neutropenic enterocolitis in nine patients (age range, 21-71 years) with acute leukemia from March 1, 1990, through February 28, 2002, was conducted. In clinical presentations, fever appears in all patients, followed by abdominal pain or tenderness (90%) and diarrhea (60%), respectively. In particular, three cases were coincidentally diagnosed as leukemia before any chemotherapy. The most common diagnostic modality used for the diagnosis of neutropenic enterocolitis was computed tomography (CT) scan (seven episodes). Medical treatments, including broad-spectrum antibiotics, bowel rest, and total parenteral nutrition, were applied to seven patients. Laparotomy with bowel resection was performed on two patients with bowel necrosis and severe peritonitis. Of all nine cases, six were fatal as a result of sepsis, a common complication of neutropenic enterocolitis. As the incidence of neutropenic enterocolitis increases in patients with acute leukemia, EPs should be alert and make an early diagnosis of this rapidly deteriorated and life-threatening disease.
