Neutrophil alkaline phosphatase activity in the urinary neutrophils of a patient with chronic myelogenous leukemia.

We report here a patient with Philadelphia chromosome (Ph)-positive chronic myelogenous leukemia (CML) in chronic phase in whom the alkaline phosphatase activity of neutrophils in the peripheral blood was low while at the same time the alkaline phosphatase content of neutrophils present in the urine was elevated. This observation provides independent clinical support for the recent experimental finding that an extrinsic factor (granulocyte colony-stimulating factor) controls alkaline phosphatase expression in human neutrophils.

[Hereditary factors in the etiology of chronic lymphocytic leukemia].

Leukocyte counts, hemoglobin concentration, PAS positivity index in lymphocytes, leukocyte alkaline phosphatase, karyotype, HLA phenotype as wall as the quality of the cellular and humoral immunity have been studied in 45 patients with chronic lymphocytic leukemia (CLL) and in 103 their closest relatives (sibs, parents). The aim was to detect the possible preleukemic condition in the relatives as a strong propensity towards developing has been previously established in families of patients with CLL. In the CLL patients our studies have confirmed the results of the determination of similar parameters by other authors, namely a higher percentage of PAS+ lymphocytes than normal together with a variety of humoral and cellular immunity disturbances. Regarding the morphological and cytochemical changes in lymphocytes in family members of the CLL patients a higher frequency of PAS+ lymphocytes have been observed: it has been established in over 10 per cent lymphocytes (normally 4-8 per cent) in 31 (30%) examinees and in 14 (13.5%) of these persons the percentage of PAS positivity was equal to that found in CLL patients. Cellular immunity examinations established that in one third of examined E rossete counts counts were lower and in 2 persons the degree of this decrease corresponded to the decrease observed in CLL patients. In one fifth of the examined family members T4:T8 ratio was reduced. In the 13 per cent of the examined M rossete counts were increased, a fact which supports the notion that immunity of B cells exists in relatives of CLL patients. The authors contend that the increased percentage of PAS+ lymphocytes and inadequate functional maturity of the T and B cells in a relatively large number of family members of the CLL patients, intimates that a hereditary disturbance in the lymphocyte make up and their role in the immunity pathways exists and could possibly represent one of the factors implicated in a high frequency of CLL in some families.

[Splenectomy in the treatment of idiopathic thrombocytopenic purpura].

During the period from 1985 till 1988, 48 patients with this disease were treated; in 28 patients (58%) conservatively treated with pronisone, immunated with thrombocytes that possessed onkovin, a remission had been achieved. In 20 patients (41%), following an unsuccessful conservative treatment, splenectomy was performed; of whom 14 were female (70%) and 6 were male (30%), with an average age of 36 years (between 20-52 years). Prior to that they were conservatively treated from 1-15 years (on the average 4.7 years). Despite the failure of the conservative treatment, an indication for splenectomy was the high doses of corticosteroids needed, as well as the appearance of serious unwanted effects of this therapy (ulcer, steroid diabetes, hypertension, osteoporosis), also the unsuccessful treatment with thrombocytes which carried onkovin. There was no surgical lethality; 2 female patients developed deep ileofemoral thrombophlebitis of the left leg, one 7 days, and the other 1 1/2 months following the surgery, and after an adnexoparametritis of the left side. Following intensive anticoagulant and fibrinolytic therapy, a complete recanalization of the vein was achieved in both female patients, without any signs of a postphlebitis syndrome. One patient who had previously been treated for 15 years with high doses of pronisone and persistently refused surgery during this period, followed splenectomy developed miliary tuberculosis which ended lethally 2 months following the splenectomy. In 14 patients (73.6%) a complete remission was attained. In 2 patients (10.5%) the number of thrombocytes was not necessary.(ABSTRACT TRUNCATED AT 250 WORDS)

Acute myelomonoblastic leukemia in a patient with multiple myeloma.

A 40-year-old man who developed acute myelomonoblastic leukemia (M4) after 7 years of treatment for multiple myeloma with the alkylating agent melphalan and steroids is presented. Leukemia was treated with courses of adriblastin, cytosine arabinoside, and thioguanin (DAT protocol), with a 8 months' survival.

[Extramedullary blast transformation in chronic granulocytic leukemia].

A patient with Ph1(Philadelphia chromosome) positive chronic granulocytic leukemia and extramedullary blast transformation (crisis) in lymph nodes of neck and axillae which appeared after 4-year of treatment with busulfan is presented. Biopsy of lymph node and histopathological examination showed lymphoblastic infiltration. The patient was treated with radiotherapy and chemotherapy with protocol COP. He survived 7 months and expired due to renal insufficiency.

Blast Crisis

[Orbital lymphomas].

Lymphomas are relatively rare in the orbit: only about 8-11% of all orbital tumours. The most common histological type is diffuse well-differentiated lymphocytic lymphoma (DWDLL--Rappaport's classification)--70%. Orbital lesions are always curable by radiotherapy, but in some 40% of these patients local recurrence or dissemination occur. The authors present two patients with diffuse well-differentiated lymphocytic lymphoma, and one patient with FCC lymphoma of centrocytic type (Kiel classification) localized in the orbit. Two of them were irradiated after an unsuccessful treatment by chemotherapy. In the third patient local radiotherapy is still in the course.

[Acute lymphoblastic leukemia in refractory anemia with "ringed" sideroblasts].

The paper deals with the progression of idiopathic refractory sideroblastic anaemia (IRSA) and its transformation to acute B lymphoblastic leukaemia (ALL). Attention is paid to haematological changes prior to leukaemia development. Acute leukaemia was best expressed in this patient by severe deterioration of dyserythropoiesis, leukopenia, and by an increase of blasts in the bone marrow over 5%. Our patient is an additional evidence to the hypothesis of the common lymphohematopoietic progenitor.

[Disseminated zygomycosis in patients with acute leukemia].

The authors present two patients with acute myeloid leukaemia and pulmonary-disseminated form of zygomycosis developed during the period of bone marrow aplasia. Diagnosis was established on necropsy on the basic of the patho-histological finding of wide, short and nonseptate hyphe with irregular branching. Hyphe were clearly recognized on Gomori methenamine Silver stained preparations. There were multiple haemorrhagic-necrotic infarcts of different organs due to the mycotic invasion of blood vessels. The authors discuss some some important diagnostic and therapeutic problems.

[Tuberculosis of the lymph nodes and spleen preceding Hodgkin's disease].

Tuberculosis of the lymph nodes is not rare today. However tuberculosis of the spleen has been very rare even in the past when many patients had suffered from tuberculosis. The appearance of Hodgkin's disease following tuberculosis is an extremely rare condition. It has thought that deficiency of cellular immunity was responsible for both tuberculosis and malignancy. We present a 44-year-old man in whom lymph node and spleen tuberculosis antedated the clinical onset of Hodgkin's disease for three years. The patient was successfully treated with tuberculostatics until he developed Hodgkin's disease; he was treated according to MOPP protocol. Six years after the onset of disease nodular lesion of the spleen was detected and splenectomy was carried out. The enlarged spleen, g in weight, was removed with tuberculoma in the lower pole, 4 cm in diameter. The tuberculostatic therapy for a year followed splenectomy. The patient stayed symptom-free, with no sign of tuberculosis. He is in the remission stage of Hodgkin's disease with normal clinical and laboratory data.
