The records of 50 patients with abdominal pain and severe neutropenia were retrospectively reviewed to identify factors that may have influenced survival and surgical decisions. Ninety-two percent of these patients had hematologic malignant neoplasms. The patients were divided into four groups: 23 treated nonsurgically who died in the hospital, 10 treated nonsurgically who survived, 10 treated surgically who survived, and 7 treated surgically who died. Abdominal distention was the only symptom or sign found to be associated with mortality. Ninety-five percent of survivors recovered their white blood cell count above 1.0 x 10(9)/L, while 70% of nonsurvivors did not. No symptom or sign was found to be pivotal in the decision for or against surgical intervention. Overall, 60% of the patients in this series died. Thirty-four percent of patients underwent a surgical procedure, the majority of whom survived. We designed an algorithm for the evaluation and treatment of neutropenic patients with abdominal pain.

In a series of 320 patients with lymphoid neoplasms treated with polychemotherapy, three patients with non-Hodgkin's lymphoma and one with myeloma were diagnosed as having neutropenic enterocolitis (NEC). All patients were adult, all had received multiple chemotherapeutic drugs and, during neutropenia, they had clinically presented with fever and abdominal pain, generally in the right lower quadrant. The diagnosis was clinical in all cases, and the imaging techniques provided only the suspicion of retro-cecal abscess in one of them. Two patients were operated on because of the development of features of peritoneal involvement, another because of septic shock and another because of retro-cecal abscess. Surgery and pathological study confirmed the diagnosis. The fundamental findings were ileocecal wall edema, mucosa ulceration, local necrosis, hemorrhage and thrombosis, and clusters of bacterial colonies without evidence of granulocytic or tumoral infiltration. NEC can develop with varying types of morphological involvement resulting in a highly variable clinical severity spectrum ranging from nonspecific abdominal symptoms to acute abdomen. Thus, diagnosis is very difficult and is only possible with a high suspicion index. It should rely on clinical data, which are unique, to assess the evolution and to indicate medical or surgical therapy. These therapeutic modalities should be individualized in each patient. All physicians treating neutropenic patients should be familiar with this condition and consider it in the differential diagnosis of abdominal pain.

We report 2 patients with myonecrosis due to Clostridium septicum and associated colon carcinoma and have reviewed the English language literature for all reported cases of atraumatic C. septicum infection. A total of 162 cases of C. septicum infection have been reported. Eighty-one percent of these patients had an associated malignancy. Thirty-four percent of all patients had associated colon carcinoma, while 40% had a hematologic malignancy. Thirty-seven percent of reported patients had an occult malignancy at the time of their infection with C. septicum. In many patients, the portal of entry was found in the large intestine. In a particularly lethal form (79% mortality) of C. septicum infection, known as "distant myonecrosis," infection metastatic from the initial site of infection causes severe myonecrosis, gangrene, and often death within hours of clinical detection. Overall, survival of patients with C. septicum infection is only 35%. Review of all cases of C. septicum infection suggests several conclusions. 1) Patients with malignancy, particularly colonic or hematologic, and patients with cyclic neutropenia who develop signs and symptoms of sepsis, especially with associated findings of abdominal pain or pain in an extremity, should be treated for possible clostridial infection. 2) C. septicum infection does not appear to be a result of a single specific defect in either humoral or cell-mediated immunity. Rather, it may occur in patients who are granulocytopenic and therefore prone to an enterocolitis. 3) Patients in whom an infection with C. septicum is found must undergo a vigorous search for malignancy following acute therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

Three cases of fatal clostridial septicemia in patients with acute leukemia are described. Predisposing factors and treatment are discussed. Clostridium septicemia should always be suspected when a patient with neutropenia suddenly develops diffuse abdominal pain, fever, and tachycardia over 120/min. The importance of early treatment with penicillin or another adequate antibiotic is discussed.

Neutropenic typhlitis is a frequently fatal disease most commonly reported in leukemics. The authors have treated eight such patients over the last 18 months. All patients had abdominal pain and sepsis during chemotherapy-induced neutropenia. CT scanning was diagnostic in six patients thought to have typhlitis. Two patients were not diagnosed before exploratory laparotomy. The authors have found nonoperative treatment highly effective in patients who do not manifest signs of peritonitis, perforation, gastrointestinal hemorrhage, or clinical deterioration. Recurrent typhlitis was frequent after conservative therapy (recurrence rate, 67 percent), however. One patient underwent an elective right hemicolectomy after a second episode, and typhlitis did not recur despite neutropenia associated with a subsequent course of chemotherapy. It is concluded that successful treatment of this disease hinges on: 1) early diagnosis provided by a high index of suspicion and the use of CT scanning, 2) nonoperative treatment for uncomplicated cases, and 3) elective right hemicolectomy to prevent recurrence.

Between 1976 and 1982, 113 children aged 6 months to 16 years with documented Epstein-Barr virus-induced infectious mononucleosis were studied prospectively, and in most instances serially. An unexpected finding was the large number of young children, less than 4 years old, with this disease. Children with infectious mononucleosis, in particular the very young, tended to have more rashes, significant neutropenia, abdominal pain (older children only), and possible hepatosplenomegaly than have been reported in adult patients. The intensity of the characteristic relative atypical lymphocytosis found in peripheral blood was age-related; it was less in the very young. Findings of failure to thrive, otitis media, and episodes of recurrent tonsillopharyngitis appeared to be unique or more closely associated with childhood disease. Complications such as thrombocytopenia with hemorrhagic manifestations, significant airway obstruction, and neurologic problems occurred more frequently whereas jaundice occurred less frequently than noted in adult patients. Six children, all less than 4 years old, developed pneumonia during the disease course. The increased availability of Epstein-Barr virus-specific testing should continue to expand our knowledge of this disease in children of all ages.

Amphethinile is a new spindle poison with a novel structure that has shown activity in the L1210, ADJ/PC6 and Walker carcinoma rodent tumours. In addition the agent appeared to have an improved therapeutic ratio compared to existing spindle poisons and is well absorbed when administered orally. The starting dose for the phase I study was 40 mg m-2 (1/10th mouse LD10) and further patients were studied at 200, 400, 800 and 1200 mg m-2, dose escalation being based on pharmacological monitoring. Significant toxic effects were seen only at 800 and 1200 mg m-2. At these doses patients experienced nausea and vomiting, light headedness during the infusion and varying degrees of lethargy following therapy. Two of six patients at 800 mg m-2 developed severe pain in the tumour bearing area 1-2 h after treatment and one experienced colicky abdominal pain. At 1200 mg m-2 two patients died within 48 h of treatment from what appeared to be vascular causes. Following these episodes the trial was discontinued. Neutropenia and alopecia occurred in two patients, one at 800 and one at 1200 mg m-2. These patients achieved the highest drug exposure in terms of area under the concentration x time curve. It was not possible to achieve an AUC consistently high enough to produce cytotoxic effects due to the occurrence of dose limiting toxicities thus amphethinile cannot at present be recommended for phase II testing by the i.v. route. The dose escalation scheme based on pharmacological monitoring resulted in a considerable saving in the duration of the trial. Further evaluation of this methodology is recommended.

The treatment of acute leukemia in childhood has been increasingly successful. Infectious complications are the major cause of morbidity and mortality among these patients receiving aggressive chemotherapy. In particular, neutropenic enterocolitis or typhlitis has had a reported mortality of 50% to 100%. The authors reviewed a series of 77 previously untreated patients with acute myelogenous leukemia begun on treatment from March 1976 to June 1984 to better define the characteristics of typhlitis and its optimum management. Twenty-five patients had episodes of typhlitis, characterized by fever, abdominal pain, and tenderness, occurring during periods of neutropenia. Ten of these patients had watery diarrhea as a major additional symptom, and nine patients had a significant episode of gastrointestinal bleeding. In seven instances, blood culture results were positive, all for intestinal flora. The episodes of typhlitis occurred most frequently during the induction therapy (19 patients). Five patients experienced typhlitis during maintenance therapy, and one patient had acute appendicitis. Two patients had typhlitis during their reinduction therapy, and of note, one had had abdominal symptoms during her initial induction. All patients were treated initially with broad-spectrum antibiotics and bowel rest. Four criteria have been used for surgical intervention: (1) persistent gastrointestinal bleeding after resolution of neutropenia and thrombocytopenia and correction of clotting abnormalities; (2) evidence of free intraperitoneal perforation; (3) clinical deterioration requiring support with vasopressors, or large volumes of fluid, suggesting uncontrolled sepsis; and (4) development of symptoms of an intra-abdominal process, in the absence of neutropenia, which would normally require surgery. Using these criteria, five patients required surgical intervention for typhlitis or its sequelae and one for acute appendicitis. There was one perioperative death resulting from miliary tuberculosis. Among the 21 patients managed medically, there was 1 death resulting from typhlitis in a patient in whom surgery was deferred because of her multiple failures to enter remission.

Neutropenic enterocolitis, also known as typhlitis or ileocecal syndrome, is a recognized complication of the treatment of hematologic malignancies and usually is fatal. The pathologic findings consist of bowel-wall ulcerations and necrosis with bacterial or fungal invasion. These findings are usually limited to the ileum, cecum, ascending colon, and appendix. The syndrome occurs in a select patient population who generally have 1) a hematologic malignancy, 2) neutropenia, 3) thrombocytopenia, 4) a recent course of chemotherapy, and 5) a recent course of antibiotics. This syndrome also can arise spontaneously in patients with aplastic anemia or cyclic neutropenia. The clinical presentation consists of a high fever and right-sided abdominal pain with evidence of peritoneal irritation. Recommended therapy is right hemicolectomy.

Ceftriaxone is a new parenteral cephalosporin with a prolonged half-life and an expanded Gram-negative spectrum. Before it can be used as a single agent for infections of unknown etiology, its efficacy in treating infections caused by Gram-positive organisms, particularly Staphylococcus aureus, must be proven. Ceftriaxone was administered to 12 children for treatment of infections due to S. aureus alone or in the presence of other organisms. Sites of infection included soft tissue, respiratory tract, bone and joint. Patients received ceftriaxone at 68 to 100 mg/kg/day in two doses for 3 to 20 days. Clinical and bacteriologic responses were satisfactory in all patients. One patient experienced abdominal pain during infusion and another developed a skin rash. Five patients had platelet counts of 500,000/mm3 or greater; four had an eosinophil count of 7% or greater and one patient had transient neutropenia. These abnormalities resolved during or after therapy. Ceftriaxone was a safe and effective single antibiotic for the treatment of infections caused by S. aureus in children.
