We reported a case of ALL complicated with acute pancreatitis caused by L-asparaginase (L-Asp). The patient was a 42-year-old man, who showed eosinophilia in peripheral blood and an increase of lymphoblast in bone marrow. He was diagnosed as ALL (L2) and treated by JALSG '87 protocol. Remission induction chemotherapy including L-Asp was administered by 5,000 IU i.v. for 10 days. The day after giving all dose of L-Asp, slight epigastralgia developed and then became severe. After two days, s-amylase was markedly elevated, and the patient was diagnosed as acute pancreatitis caused by L-Asp. He was treated conservatively, but hyperglycemia occurred. The epigastrial tumor was palpable and gradually grew in size. CT-scan and abdominal ultrasonography revealed pancreatic pseudocyst, so he was treated by percutaneous cyst drainage. The patient died of a relapse of ALL. The prophylaxis and early diagnosis of the pancreatitis and hyperglycemia caused by L-Asp are very difficult. We have to examine more cases and pay greater attention to the chemotherapy, including L-Asp.

We encountered a 44-year-old woman with suspected chronic myelocytic leukemia (CML) in the acute phase that was difficult to be differentiate from Philadelphia chromosome (Ph)-positive acute lymphoblastic leukemia (ALL). At disease onset, her bone marrow showed an increase in blasts that were negative for myeloperoxydase (MPO) and Positive for CD10, 19, 34, and HLA.DR. Standard type Ph was detected by chromosome analysis, and both major and minor BCR/ABL m-RNA were detected by reverse-transcriptase polymerase chain reaction (RT-PCR) methods. Neutrophil alkaliphosphatase (NAP) score was normal, and neither eosinophilia nor basophilia was observed in peripheral blood. Under a presumptive diagnosis of Ph-positive ALL (L2), the patient was given AdVP (doxorubicin, vincristine, and prednisolone) therapy followed by a regimen of LMVP (L-asparaginase, mitoxantrone, and VP), and obtained a complete remission 2 months later. At that time, FISH analyses of her bone marrow and blood cells no longer detected bone marrow Ph or BCR/ABL fusion gene. A month later, however, the leukemia relapsed with an increase in MPO-positive blasts in bone marrow, and the patient died soon thereafter. We finally concluded that her leukemia was not Ph-positive ALL, but CML in the acute phase at disease onset.

This report describes the long-term (23 years) follow-up of a pediatric patient with acute lymphoblastic leukemia and eosinophilia who underwent multiple valve replacements. An 8-year-old boy with this complex disease was admitted in January 1984 and treated with 6-week course of vincristine, L-asparaginase, and prednisolone, which induced complete remission. He developed atrioventricular valvular insufficiency and infectious endocarditis at 13.5 and 17.3 years of ages, respectively, with progressive development of congestive heart failure. At 18.6 years of age, he underwent prosthetic valve replacement of both atrioventricular valves; the mitral valve was replaced with a mechanical prosthetic valve and tricuspid valve with a bioprosthetic valve. Histopathological examination of the ventricular endomyocardium showed extensive fibrous degeneration and persistent infiltration of eosinophils and lymphocytes. The right-side prosthesis was replaced twice, at 22.4 and 29 years of ages, due to degeneration of bioleaflets and thrombosis of the mechanical valve, respectively. Although he tolerated all surgical procedures, he developed liver cancer at 31 years of age and died. Autopsy could not be performed. The present study indicates that a subset of patients in complete remission of acute lymphoblastic leukemia and eosinophilia can show persistent myocardial eosinophilic infiltration and are at risk of late cardiac disease.
