We previously reported results of a Phase II trial of UFT [Taiho Pharmaceutical Ltd., Tokyo, Japan; (BMS-200604) Bristol-Myers Squibb, Princeton, NJ], an oral 4:1 molar concentration of uracil and tegafur, plus oral leucovorin for metastatic colorectal carcinoma (Pazdur et al., J. Clin. Oncol. 12:2296-2300, 1994]. Our results demonstrated that a 28-day schedule of this combination produced a response rate similar to that obtained with conventional intravenous fluorouracil (5-FU)-plus-leucovorin regimens but without the severe or life-threatening neutropenia or oral mucositis that complicates intravenous 5-FU regimens. The current Phase I trial examines the dose-limiting toxic effects and maximum tolerated dose of a 14-consecutive-day schedule of UFT plus oral leucovorin in 14 patients who had histologically proven cancer and had received prior chemotherapy. The daily UFT plus leucovorin dose was divided into three doses administered orally every 8 hours. In this study, the UFT dose was escalated while the leucovorin dose remained at 150 mg/day. Of the 14 patients, 4 were initially treated at the 350-mg/m2/day UFT level for 14 days without any dose-limiting toxic reactions. Subsequently, another 7 patients were treated at the 400-mg/m2/day level; grade 3 diarrhea developed in 3 of these 7 (with severe abdominal cramping in 2 cases and severe nausea and vomiting unresponsive to antiemetics in the third). To better define the starting dose for phase II studies, an additional 3 patients were treated at the 350-mg/m2/day dose level. Of the total 7 patients treated at 350 mg/m2/day, grade 3 toxic events (diarrhea) developed in 2 patients. Grade 1-2 toxic effects noted at this level included fatigue, stomatitis, skin rash, abdominal pain, nausea, and vomiting. Neither partial nor complete responses were observed in this trial. The maximum tolerated dose of this schedule is 350 mg/m2/day UFT plus 150 mg/day oral leucovorin. However, because of this schedule's inferior dose intensity compared with that of the 28-day schedule of UFT plus leucovorin, subsequent development of UFT in the United States has focused on the 28-day regimen.

A syndrome involving periodic fever, pharyngitis, adenitis and aphthous stomatitis is described in 8 children. Attacks are characterized by abrupt onset of fever and, in addition to the above symptoms, by malaise, headache and abdominal pain. Mild leukocytosis and elevation of the erythrocyte sedimentation rate are found in the laboratory. Patients exhibit normal growth and development and are otherwise healthy. PFAPA is clinically benign, with no long-term sequelae. Recognition and diagnosis of the syndrome eliminate the need for intensive work-up. The cause remains unknown. No evidence linking bacterial, viral, or fungal pathogens to this syndrome has been found. No patient has exhibited atypical lymphocytosis or neutropenia, and all patients had normal levels of immunoglobulin. All had received antibiotics early in the course of their illness but without effect. Cimetidine has been discussed in the literature as a possible treatment, but the results are controversial.

Seven patients with gastrointestinal necrosis following paclitaxel chemotherapy are reported. Four of seven patients had platinum refractory disease, while 3/7 patients received primary paclitaxel therapy. Complications occurred 5 to 16 days following paclitaxel therapy. The most common clinical presentation was fever (7/7 patients), neutropenia (6/7 patients), and abdominal pain (6/7 patients). All seven patients developed gastrointestinal necrosis following the first cycle of paclitaxel chemotherapy. The exact mechanism by which this complication occurs is poorly understood. We postulate that gastrointestinal necrosis may be the result of a direct drug effect on the gastrointestinal epithelium and might involve a synergistic interaction between compromised bowel and paclitaxel-induced mitotic arrest. We observe that the incidence of gastrointestinal necrosis in patients with platinum refractory disease is 4 of 108 patients (3.7%). The incidence of this complication in patients receiving primary paclitaxel at our institution is 3 of approximately 128 patients (2.3%). Eighteen cases to date have been identified in the literature. A high index of suspicion of this complication should be considered for patients presenting with neutropenic fever and abdominal pain following paclitaxel chemotherapy.

Sixteen cases of acute idiopathic toxaemic colitis developed in a veterinary hospital over a period of three years. Before the onset of colitis, 15 horses had received antibiotics, 11 had undergone general anaesthesia and various surgical procedures, and 10 had been treated with non-steroidal anti-inflammatory drugs. The horses had acute onset, profuse watery diarrhoea, profound depression, mild to moderate abdominal pain, reduced intestinal borborygmi, tachycardia, dehydration and endotoxic shock. Leucopenia, neutropenia and pyrexia were common early indicators of impending colitis. Metronidazole appeared to be an effective treatment; eight horses treated with metronidazole survived whereas five of seven horses that received other treatments, but no metronidazole, died or had to be euthanased. The aetiology of the colitis could not be determined, but the clinicopathological features resembled those of colitis attributed to an intestinal overgrowth of Clostridium perfringens type A. No Salmonella species were isolated from 52 samples of faeces, colonic contents and colonic mucosa which were collected from the horses antemortem and postmortem.

An effective local-regional therapy is needed for adenocarcinomas of the pancreas. Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton NJ) may enhance the effect of radiation therapy. Paclitaxel synchronizes cells at G2/M, a relatively radiosensitive phase of the cell cycle. We have shown that response to paclitaxel and concurrent radiation (paclitaxel/RT) was not affected by p53 mutations in non-small cell lung cancer (NSCLC). This suggested that paclitaxel/RT was a rationale treatment approach for other malignancies which frequently harbor p53 mutations such as upper gastrointestinal malignancies. We have completed a phase I study of paclitaxel/RT for locally advanced pancreatic and gastric cancers. The maximum tolerated dose (MTD) of paclitaxel was 50 mg/m2/week for 6 weeks with abdominal radiation. The dose limiting toxicities were abdominal pain within the radiation field, nausea and anorexia. Twenty-five patients with locally advanced pancreatic cancer have now completed treatment at the phase II dose level of paclitaxel 50 mg/m2/week with 50 Gy concurrent RT. Thus far, the only grade 3/4 toxicities have been hypersensitivity reactions in 2 patients, asymptomatic grade 4 neutropenia in 3 patients, and non-neutropenic biliary sepsis in 1 patient. Of the first 22 assessable patients treated at the phase II study, 8 obtained a partial response (PR) for a preliminary response rate of 36%. These findings demonstrate that paclitaxel/RT is well tolerated with substantial activity for locally advanced pancreatic cancer.

Cryptosporidium was detected in 21 (3.8%) individual stool samples collected from 553 pediatric patients hospitalized in our center employing a Telemann concentration technique (formalin-ether-centrifugation) and stained with the modified Kinyoun method. The mean age of populations with Cryptosporidiosis (16 boys and 5 girls) was 11 months; 15 months for girls and 6.5 for boys. Ages of 81% of them were less than 19 months. Seventy-six per cent of patients lived on the outskirts of Buenos Aires and 71% lacked pretreated running water at home. In 62% of the cases parasitological diagnoses coincided with warm seasons. At diagnosis mucous (63%) or watery (36%) diarrhea was presented in 90% of the patients with a median of 5 (3-8) bowel movements per day. Fever was presented in 66% of patients while abdominal pain and vomits in 60% and 52%, respectively. The median time from hospitalization up to parasitologic diagnosis was 20 days. Concomitant diseases observed were malnutrition, acute leukemia, bronchiolitis, HIV infection, anemia, celiac disease, myelofibrosis, vitelline sac tumor, neutropenia, osteosarcoma and dehydration. Cryptosporidiosis in our environment seems to occur more frequently in children younger than 18 months of age; who present diarrhea; are immunodeficient; come from a low socioeconomical background; and who live in poor sanitary conditions with no potable running water.

An effective locoregional therapy is needed for adenocarcinomas of the pancreas, stomach, and gastroesophageal junction. Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) may enhance the effect of radiation therapy (RT). Paclitaxel synchronizes cells at G2/M, a relatively radiosensitive phase of the cell cycle. We have shown that response to paclitaxel and concurrent RT (paclitaxel/RT) was not affected by p53 mutations in non-small cell lung cancer. This finding suggested that paclitaxel/RT was a rational treatment approach for other malignancies that frequently harbor p53 mutations, such as upper gastrointestinal malignancies. We completed a phase I study of paclitaxel/RT for locally advanced pancreatic and gastric cancer. The maximum tolerated dose of paclitaxel was 50 mg/m2/wk for 6 weeks with abdominal RT. The dose-limiting toxicities were abdominal pain within the radiation field, nausea, and anorexia. Phase II studies are now under way. Twenty-five patients with locally advanced pancreatic cancer have been entered at the phase II dose level of paclitaxel 50 mg/m2/wk with concurrent RT (total dose, 50 Gy). Thus far, the only grade 3/4 toxicities have been hypersensitivity reactions (n = 2), asymptomatic grade 4 neutropenia (n = 3), and nonneutropenic biliary sepsis (n = 1). Of the first 18 assessable patients with pancreatic cancer treated on the phase II study, six obtained a partial response, for a preliminary response rate of 33%. In the phase II study for locally advanced gastric cancer, 20 patients have been enrolled. Of the first 19 patients who have completed treatment, nine (47%) had grade 3/4 toxicities, including nausea, anorexia, esophagitis, and gastritis. Of the first 16 patients with gastric cancer, complete and partial responses have been observed in one and eight patients, respectively, for a preliminary response rate of 56%. We have also completed treatment on 24 patients with potentially resectable adenocarcinomas of the gastroesophageal junction with neoadjuvant paclitaxel 60 mg/m2 and cisplatin 25 mg/m2, weekly for 4 weeks, with concurrent RT (total dose, 40 Gy) followed by surgical resection. Ten patients (41%) had grade 3/4 toxicities, including neutropenia, nausea, and dehydration. Of 24 patients, four complete responses (17%) and 14 partial responses (58%) were observed, for an overall response rate of 75%. Severe esophagitis was uncommon, making this a well-tolerated outpatient regimen for adenocarcinomas of the distal esophagus. These findings demonstrate that paclitaxel-based chemoradiation for locally advanced upper gastrointestinal malignancies is well-tolerated with substantial activity.

A prospective study was carried out to assess the occurrence and character of adverse cutaneous reactions in patients receiving ticlopidine hydrochloride to prevent subacute thrombosis after having undergone placement of coronary stents. During a 1-year period such patients were requested to report any adverse cutaneous reactions, and those with skin reactions were referred for dermatological evaluation. Among the 136 patients who underwent stent placement by one of the authors, 20 were referred for dermatological evaluation. Of these, 16 (11.8%) fit the case definition of ticlopidine-associated cutaneous reactions. In the first 8 consecutive patients ticlopidine was withdrawn (in 2 of these a rechallenge test was later performed); in the next 8 patients ticlopidine was not discontinued before completion of the intended 4-week period of treatment. Patients remained under weekly follow-up and underwent a weekly blood count. Skin biopsies were obtained in 5 patients with different types of eruptions. The skin reactions appeared from 2 to 21 days after commencement of ticlopidine (mean, 10 days), lasting from 2 to 30 days (mean, 5 days). Only 3 patients had other adverse effects: neutropenia in 1 and abdominal pain and nausea in 2. The most common presentations were urticaria, pruritus, and maculopapular eruption. In 3 patients there were previously unreported reactions: fixed drug eruption, erythromelalgia-like eruption, and erythema multiforme-like eruption. Of note was the rapid clearing of the skin eruption in most cases even when the drug was not withdrawn. It was concluded that adverse cutaneous reactions are relatively common in association with ticlopidine treatment but that serious reactions are rare and the disappearance of the signs and symptoms is rapid, suggesting that discontinuation of the drug is not usually imperative.

This was an open study of oral antifungal prophylaxis in 103 neutropenic children aged 0-14 (median 5) years. Most (90%) were undergoing transplantation for haematological conditions (77% allogeneic BMT, 7% autologous BMT, 6% PBSC transplants and 10% chemotherapy alone). They received 5.0 mg/kg itraconazole/day (in 10 mg/ml cyclodextrin solution). Where possible, prophylaxis was started at least 7 days before the onset of neutropenia and continued until neutrophil recovery. Of the 103 who entered the study, 47 completed the course of prophylaxis, 27 withdrew because of poor compliance, 19 because of adverse events and 10 for other reasons. Two patients died during the study and another five died within the subsequent 30 days. No proven systemic fungal infections occurred, but 26 patients received i.v. amphotericin for antibiotic-unresponsive pyrexia. One patient received amphotericin for mycologically confirmed oesophageal candidosis. Three patients developed suspected oral candidosis but none was mycologically proven and no treatment was given. Serious adverse events (other than death) occurred in 21 patients, including convulsions (7), suspected drug interactions (6), abdominal pain (4) and constipation (4). The most common adverse events considered definitely or possibly related to itraconazole were vomiting (12), abnormal liver function (5) and abdominal pain (3). Tolerability of study medication at end-point was rated as good (55%), moderate (11%), poor (17%) or unacceptable (17%). Some patients had poor oral intakes due to mucositis. No unexpected problems of safety or tolerability were encountered. We conclude that itraconazole oral solution may be used as antifungal prophylaxis for neutropenic children.

To develop a T-cell-based therapy for carcinomas, the superantigen staphylococcal enterotoxin A (SEA) was supplied with tumor specificity by means of a recombinant fusion of the Fab fragment of the monoclonal antibody C242 recognizing human colorectal (CRC) and pancreatic carcinomas (PC). Using this Fab-SEA fusion protein (PNU-214565), potent cytotoxicity by activation of T cells can be obtained in the targeted area. Twenty-one patients with CRC and 3 with PC were treated with single, escalating doses of PNU-214565 to establish the maximum tolerated dose (MTD) and to define toxicities. The doses ranged from 0.01 ng/kg to 4.0 ng/kg with three patients at each dose level, except for the dose of 1.5 ng/kg with which six patients were treated because of dose-limiting toxicity. Adverse events (AE) were transient: 13 patients experienced mild to moderate fever. In one patient, a grade 3 fever was followed by a grade 2 hypotension. Other mild or moderate AEs were fatigue, nausea, vomiting, diarrhea, and abdominal pain. No significant hematological toxicity occurred. Immune activation was highly variable with strong activity in peripheral blood seen only in two patients at the dosage level 1.5 ng/kg. They showed pronounced elevations of interleukin-2 (IL-2), IL-6, tumor necrosis factor-alpha, and interferon-gamma, 3-5 hours after the start of infusion. In one patient, IL-2 and IL-6 increased substantially (2,925 U/mL and 32,000 U/mL) concomitantly with grade 3 fever and transient grade 2 neutropenia, grade 2 lymphopenia, and grade 2 monocytopenia. In conclusion, a single 3-hour infusion of PNU-214565 could be safely administered up to 4 ng/kg. MTD was not determined. Instead, a repeat-dose trial was initiated starting at 0.5 ng/kg, considered safe in this trial, with the objective of defining the MTD.
