A combination of cyclosporine (CSA) and methylprednisolone (MP) was used as graft-versus-host disease (GVHD) prophylaxis in 25 patients age 11-47 years (median 27 years) who received HLA-compatible sibling marrow transplants after myeloablative therapy for leukemia, myelodysplasia or lymphoma. CSA was initiated at 3 mg/kg/day in two divided doses, and the dose was adjusted to maintain a trough whole blood h.p.l.c. concentration between 200 and 800 ng/ml. While on i.v. CSA, the dose of CSA was increased for 10 of the 25 patients. The actuarial rate of grades II-IV acute GVHD was 37%. Those patients who developed moderate to severe GVHD had a significantly higher early mortality than those who did not (56% vs 12%, p = 0.02). There was a significant association between the development of acute GVHD and a mean week 2 CSA trough concentration less than 250 ng/ml. Life threatening regimen-related toxicities in the first 100 days included capillary leak syndrome, acute pancreatitis and small bowel perforation. Although the combination of CSA and MP in this dosing schedule was active in preventing acute GVHD, nephrotoxicity remained a problem, and outcome was limited by the inability to achieve the target CSA trough concentration in a substantial proportion of patients.

We report two cases of adult T-cell leukemia associated with acute pancreatitis and hypercalcemia. After sudden onset of epigastralgia, acute pancreatitis and hypercalcemia were found in both patients. There were no diseases that could explain the acute pancreatitis except for hypercalcemia probably due to adult T-cell leukemia. Thus we considered that hypercalcemia due to adult T-cell leukemia had led to acute pancreatitis. This is the first report of such a complication in adult T-cell leukemia.

We report here three patients with sepsis and one with acute pancreatitis and possible sepsis who developed granulocytic fragments on blood smears obtained prior to death. In case 1, these fragments were identified cytochemically. In case 3, granulocytic cytoplasmic projections and fragments were identified by electron microscopy of the buffy coat. All patients had leukerythroblastosis. The average corrected white blood count (WBC) was 46 X 10(9)/liter with 34 nucleated red blood cells (nRBC)/100 WBC. Patient 1 had thrombocytosis whereas patients 2, 3, and 4 were thrombocytopenic. Terminal complement levels were decreased in patients 3 and 4 as previously noted in sepsis (Sprung CL, Shultz DR, Marcial E, et al.: Complement activation in septic shock patients. Crit Care Med 14:525, 1986). A general correlation between nRBC and granulocytic fragments/100 hpf (high power field) was observed in patients 3 and 4. Granulocytic fragments were not identified on the blood smears of several patients with leukemoid reactions without erythroblastosis. Although the precise etiology of these fragments is unclear, we believe their recognition is important because all patients died within 32 hours after granulocytic fragments were identified. Furthermore, these fragments can falsely elevate the platelet count. Although myeloid fragments have previously been noted in leukemia and lymphoma, this is the first report of their association with conditions unrelated to hematologic neoplasms. These fragments can easily be recognized by careful examination of the blood smear and represent a newly recognized aspect of the septic shock syndrome.

Infection, hemorrhage and adult respiratory distress syndrome (ARDS) are pulmonary complications occurring after remission induction therapy for acute leukemia. The aim of this study was to analyze the incidence of these causes by serial roentgenogram, clinical, microbiological and laboratory tests in 21 patients (pts) with relapsed acute leukemia (18 X myeloid, 3 X lymphoblastic), an AML-pt (acute myeloid leukemia) suffering from secondary leukemia, and three pts with primary refractory leukemia following treatment with intermediate (IM) and high-dose cytosine arabinoside (HD-Ara C), in combination with amsacrine (AMSA)(n = 19), etoposide (VP 16) (n = 5) or Mitoxantrone (n = 1). Eleven out of 25 pts developed pulmonary complications, one of them with massive hemoptysis and roentgenographic signs of pulmonary bleeding, one suffering from protracted shock after a tumor lysis syndrome, two pts showing symptoms of a cardiogenic pulmonary edema complicating severe Candida pneumonia in one case and legionnaires' disease in the other. Seven of the eleven pts had a non-cardiogenic pulmonary edema with respiratory failure 1-14 days after cessation of induction or consolidation therapy. In six of the seven, there were no signs of cardiogenic, infectious or metabolic reasons, including fluid overload, for the pulmonary edema, one had as a contributing factor a Candida infection of the lung. Three of the seven patients recovered, four died (two following IM and two after HD-Ara C). Other adverse side effects, clearly attributable to HD-Ara C, included delirious state (n = 3), generalized erythema (n = 3), acute pancreatitis (n = 2), acute abdomen (n = 1) and conjunctivitis in almost all patients.(ABSTRACT TRUNCATED AT 250 WORDS)

In the management of children with acute lymphoblastic leukemia, L-asparaginase has become established as an effective drug in the usual multi-agent therapy; and the significance of pancreatitis as a complication of this drug is well recognized. Less well appreciated, however, is the progression of such pancreatitis in some patients to pseudocyst formation and the possible necessity for surgical management. Two adolescent girls who developed pancreatic pseudocysts while being treated with L-asparaginase are described in this report. Both were being treated for acute lymphoblastic leukemia for periods of 18 and 4 months, respectively, prior to the onset of pancreatitis. Both were in remission of their leukemic disease when typical clinical and laboratory manifestations of acute pancreatitis developed. In one girl, a pancreatic pseudocyst became apparent 2 weeks following the diagnosis of acute pancreatitis and in the other girl, this complication developed over a period of 8 weeks. The usual nonsurgical management of pancreatitis over protracted periods of time was ineffective in the treatment of the pseudocysts. Surgical drainage (internal in one and external in the other) was successful in both in eradicating the pseudocyst, and in neither did further evidence of pancreatic disease subsequently occur. In both resumption of chemotherapy, omitting L-asparaginase, was well tolerated. One has been in remission of leukemia and in good health for a 3-year period of follow-up observation, while the other subsequently had a relapse of leukemia and died 18 months following the onset of pancreatitis.

The clinical signs and symptoms of a patient induced us to consider critically the so far known side effects of azathioprine. The literature concerning 643 patients treated with azathioprine reports on reactions as changes in blood count, gastro-intestinal complaints, intrahepatic cholestasis, acute pancreatitis, and leukemia. Irreversible side effects occurred in four cases.

L-Asparaginase-induced pancreatitis is an uncommon but potentially lethal complication. An 8-year-old girl with acute lymphoblastic leukaemia developed acute pancreatitis following treatment with asparaginase. Clinical and laboratory improvements were evident after treatment with somatostatin, with no complications of pancreatitis. Induction therapy for the leukaemia was able to be continued and complete remission was documented during the course of pancreatitis and somatostatin treatment, suggesting a beneficial role of somatostatin in the management of asparaginase-induced pancreatitis.

The behavior of plasma von Willebrand factor (vWF) in patients with acute leukemia (n = 5), decompensated cirrhosis (n = 10), and acute pancreatitis (n = 5) was investigated to evaluate whether the systemic proteolytic states associated with these diseases had affected the structure and function of the molecule. vWF antigen and, to a lesser degree, ristocetin cofactor activity in patient plasma were high. Multimeric analysis of plasma vWF revealed loss of high molecular weight multimers. The subunit composition and proteolytic pattern of vWF immunopurified from patient plasmas and reduced were studied by sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis followed by transblotting and probing with monoclonal antibodies that distinguish cleavages caused by plasmin from those caused by other proteases. There was marked reduction of the relative concentration of the native vWF subunit of 225 Kd in all patient groups, indicating heightened cleavage of the protein. The concentrations of 189- and 140-Kd vWF fragments, normally present in plasma, were increased in cirrhosis and pancreatitis but not in leukemia. Novel fragments, ranging in size from less than 225 to approximately 120 Kd were present in leukemia and cirrhosis, including plasmin-generated fragments of 176 and 145 Kd. These data indicate that in clinical conditions in which there is heightened proteolysis vWF is degraded in vivo by plasmin and other proteases. Degraded vWF may be less effective than native vWF in supporting primary hemostasis, thereby being a cofactor in the multifactorial bleeding diathesis accompanying systemic proteolytic states.

Current data on patients treated with human growth hormone (GH) were analyzed for the following safety topics. New leukemia. Thirteen of 46 new cases of leukemia were in non-Japanese patients without risk factors for leukemia (compared with at least 13 new cases expected). A possible increased occurrence of leukemia with GH treatment appears to be limited to patients with risk factors. Nonleukemic extracranial neoplasms. The number of cases reported (10) does not differ significantly from the number expected. Acute pancreatitis. In five of the seven cases reported risk factors (renal failure, valproic acid use, insulin-dependent diabetes mellitus) were present. The available data do not indicate a clear cause-and-effect relation between GH therapy and pancreatitis. Prepubertal gynecomastia. Of 15 possible cases, two were pubertal, eight resolved or improved with continued GH therapy, and two resolved with the cessation of GH therapy. An effect of GH treatment on prepubertal gynecomastia remains unknown. Scoliosis. Scoliosis is reported in fewer than 1 percent of the patients in the National Cooperative Growth Study (general-population prevalence, 1.5% to 3%). Curvature progression can occur during growth acceleration, and a causal association with GH treatment is not substantiated. Pigmented nevi. Nevi growth may be increased with GH treatment. Biopsies have detected no neoplasia or premalignant nevi transformations.
