Fourteen children (ages 2-15 years) with acute leukemia in relapse were treated with daily recombinant interferon gamma for 14 days by subcutaneous injections at fixed dose levels of 0.1, 0.25, 0.5, or 0.75 mg/m2 (1.0, 2.5, 5.0, or 7.5 x 10(6) units/m2) without intrapatient escalation. Patients received a second 14-day course of therapy followed by thrice weekly administration unless there were signs of progressive disease or grade 3 or 4 toxicity. Side effects in the 13 evaluable patients included fever (n = 10), fatigue (9), decreased Karnofsky performance score (8), hypertriglyceridemia (8), myalgia (5), weight loss > 5% (4), elevated liver transaminases (4), and abdominal pain (3). There was only one grade 4 toxicity: one of the six patients at the 0.5 mg/m2 dose level developed reversible acute renal failure. One patient died of gastrointestinal hemorrhage due to disease-related refractory thrombocytopenia. One child had an oncolytic response and two others stable disease for 138 and 148 days. An appropriate dose level for phase II studies in children is 0.5 mg/m2 per day.

Human blood monocytes (Mo) and monocyte-derived macrophages (M phi) are known to be potent antitumor cytotoxic effector cells through activation with recombinant human interferon gamma (rIFN-gamma), bacterial muramyldipeptide or the synthetic derivative muramyltripeptide phosphatidylethanolamine entrapped in liposomes (L-MTP-PE). Large-scale generation of ex vivo activated Mo from the blood of cancer patients proved feasible. We report our experience with a fixed rotor speed counterflow centrifugation elutration (CEE) procedure using the newly available Beckman high capacity JE-5.0 rotor system that reproducibly isolates up to 1.0-1.5 x 10(9) Mo with greater than 90% purity, in suspension and functionally intact derived from peripheral blood mononuclear cell-enriched suspensions obtained by leukapheresis (LP) from healthy volunteers and cancer patients. The semiclosed, easy to handle CCE system, was adapted to a sterile technique that permitted clinical trials in adoptive monocyte immunotherapy. Freshly isolated Mo did not lose morphological or functional integrity and had no spontaneous activation. Their abilities to become activated to the cytotoxic state after 18-h stimulation with 500 U/ml rIFN-gamma or 1 microgram/ml L-MTP-PE and to differentiate into matured M phi in vitro were not altered. The system was therefore used to isolate large numbers of Mo for a phase I clinical trial of intraperitoneal immunotherapy with L-MTP-PE activated autologous Mo in nine patients with peritoneal carcinomatosis. Each patient received weekly Mo infusions (n = 5) with an intrapatient dose escalation schedule (from 10(7) to 10(9) Mo). Toxicities were mild including fever, chills and abdominal pain. There was no treatment-induced thromboembolic event or capillary leak syndrome.(ABSTRACT TRUNCATED AT 250 WORDS)

Peritoneal tuberculosis remains a common problem in impoverished areas of the world. Immigrants and AIDS patients are two population groups at particular risk for abdominal tuberculosis in our country. The most common presenting symptoms of tuberculous peritonitis are abdominal pain, ascites and weight loss in more than 80% of cases. Results of sonographics studies are non specific and high serum CA 125 levels can be found. Pulmonary tuberculosis is concomitantly discovered in 50% of cases. Tuberculous peritonitis is of the exsudative type in 95% of cases and requires multiple studies of peritoneal fluid. Tuberculous peritonitis is suspected when exsudate and lymphocytes are present with no malignant cells, and high interferon gamma and adenosine desaminase activity. AFB is detected in the peritoneal fluid cultured conventionally in 80% of cases. Laparoscopy combined with peritoneal biopsy is effective for the diagnosis of tuberculous peritonitis in 75 to 85% of cases. Peritoneal tuberculosis is treated with antituberculous drugs for a period of nine months.

Chronic granulomatous disease (CGD), an inherited disorder of phagocytic leukocyte function, is characterized by recurrent infections with catalase-positive organisms. Gastrointestinal (GI) tract involvement, present in the majority of affected individuals, may be present initially and recurrently, mimics other entities such as inflammatory bowel disease, and causes substantive morbidity and mortality. Disorders of motility, ulceration, obstruction, and infection (e.g., abscesses) occur from the mouth to the anus and stereotypically manifest with vomiting, diarrhea, abdominal pain, weight loss, and fever. Careful physical examination, in concert with appropriate diagnostic studies, is necessary to delineate intraabdominal pathologic processes. Abdominal radiographs, ultrasonography, computerized tomography, and endoscopy are useful ancillary diagnostic procedures. Drainage of accessible abscesses, antimicrobial therapy based on organisms cultured from blood and tissue, and interferon gamma may lead to suppression or eradication of infections and resolution of symptoms. Corticosteroids are useful for gastric outlet obstruction and sulfasalazine and cyclosporine for large bowel disease. Gallbladder dysfunction may be ameliorated, as in our patient, with administration of cholestyramine.
