Granulocyte function in chronic granulocytic leukemia. II. Bactericidal capacity, phagocytic rate, oxygen consumption, and granule protein composition in isolated granulocytes.

The initial rate of phagocytosis, oxygen consumption rate during phagocytosis, bactericidal capacity against Escherichia coli, and the granule protein composition of isolated mature-appearing granulocytes were studied in 23 patients with chronic granulocytic leukemia (CGL) with the simultaneous use of normal controls. The initial rate of phagocytosis was decreased (p less than 0.05) in the CGL patient group, as were oxygen consumption rate (p less than 0.001) and bactericidal capacity (p less than 0.001). Kinetic analysis of the ingestion rate showed CGL granulocytes to have the same capacity to bind the particles as normal granulocytes. Both specific and primary granule protein deficiencies were shown for CGL granulocytes, and these deficiencies were more pronounced at or near blast cell transformation. Analysis of all different granulocyte function parameters showed an inverse correlation to white blood cell counts (p less than 0.01) and to the percentage of immature granulocytes in peripheral blood (p less than 0.001). The leukocytosis doubling time was progressively shortened during the chronic course of the disease. A correlation was found between granulocyte function parameters and leukocytosis doubling time (p less than 0.001), indicating that granulocyte function was progressively deteriorating during chronic phase CGL, and may be an expression of increasing disturbance of the differentiation process.

[Bladder carcinoma producing granulocyte colony-stimulating factor (G-CSF): a case report].

An 84-year-old male was admitted to our hospital with complaints of leg edema and general fatigue. He had undergone transurethral resection of transitional cell bladder cancer, grade 3, pT1b, one year previously. The computed tomographic scan revealed a hypoattenuating bladder tumor, protruding extravesically. Laboratory examination showed remarkable leukocytosis of 46,900/mm3 in the peripheral blood and high value of granulocyte colony-stimulating factor (G-CSF) 226 pg/ml (normal: less than 30 pg/ml). The resection of the tumor (partial cystectomy) was performed. The histological diagnosis was transitional cell carcinoma, grade 3. The production of G-CSF was confirmed by immunohistochemical examination in the recurrent tumor and the surgical sample from the transurethral resection. The leukocyte count in the peripheral blood decreased to the normal range after surgery. But leukocytosis recurred one month postoperatively and the computed tomographic scan revealed intrapelvic tumor recurrence. He died due to drastic progression of recurrent tumor at three months postoperatively.

[A case of large cell carcinoma of the lung which is suspected of producing granulocyte colony-stimulating factor].

A 41-year-old male complaining of fever and left shoulder pain was admitted to our hospital for further examination of an abnormal shadow on chest X-ray film. His laboratory data on admission showed marked leukocytosis and elevation of serum alkaline phosphatase. The diagnosis of large cell carcinoma of the lung was made by percutaneous biopsy and he was staged clinically as T3N0M0. Chemotherapy including CDDP and VDS resulted in resolution of symptoms and normal laboratory data. After three courses of chemotherapy, he underwent left upper lobectomy with chest wall resection. Pathological diagnosis of the resected tumor was large cell carcinoma with giant cells, and he was staged postoperatively as T3N0M0. Since colony stimulating activity was demonstrated in both homogenate of tumor cells and tumor conditioned medium, and preoperative serum granulocyte colony-stimulating factor (G-CSF) was 105 pg/ml, we concluded that leukocytosis in this patient was caused by G-CSF produced by tumor cells. The patient was in good health two years after surgery with no signs of recurrence.

[Pulmonary undifferentiated carcinoma associated with severe inflammatory response; report of 2 cases].

We present 2 cases with pulmonary undifferentiated carcinoma accompanying severe inflammatory responses. Both patients initially complained high-grade fever. Laboratory data on admission showed leukocytosis and elevation of serum CRP level. In both cases, the tumors were characterized by a low-density mass with the enhanced wall on chest computed tomography (CT). The presence of tumor cells could not be identified by bronchoscopical examination. One patient was suffered from left adrenal metastasis at the diagnosis. Both patients underwent pulmonary resection for the primary tumor. The tumors consisted of marked necrotic tissue and were histologically diagnosed as pulmonary undifferentiated carcinoma cells with sarcomatous elements, which was compatible with pleomorphic carcinoma by new World Health Organization (WHO) classification (1999). After operation, systemic inflammatory response such as high-grade fever, leukocytosis, high level of serum CRP continued and progressed. Furthermore, extrathoracic metastatic lesions newly appeared. Both patients died within 100 days after operation.

Induction of colitis in young rats by dextran sulfate sodium.

Models using dextran sulfate sodium (DSS) to induce experimental colitis in rodents have been performed mostly in adult animals. For this reason, we aimed to develop a model of colitis in young rats. DSS was administered to 30-day-old rats at concentrations ranging from 0.5 to 5% in drinking water. Young rats were remarkably sensitive to DSS since clinical symptoms rapidly rose with 5% DSS and most animals died after the fifth day. With 1 and 2% DSS, the severity of mucosal lesions was also high on day 7, the animals showing leukocytosis and anemia. At 0.5% DSS, leukocytosis and mild colonic lesions were induced. This concentration of DSS significantly increased myeloperoxidase activity and goblet cell number in the colon, indicating mucosal inflammation. Since food consumption was not reduced by 0.5% DSS, we suggest that this protocol can be used to study the effects of dietary supplements on intestinal inflammatory processes.

[Infection status and clinical significance of Epstein-Barr virus in pediatric leukemia---a report of 35 cases].

BACKGROUND & OBJECTIVE: Epstein-Barr virus (EBV) is associated with genesis of many human tumors. This study was to detect EBV infection in pediatric leukemia, and to explore its clinical significance. METHODS: EBV DNA in peripheral blood mononuclear cells in 35 pediatric leukemia patients, including 26 cases of acute lymphoblastic leukemia (ALL) (24 received initial treatment and 2 received retreatment), 8 cases of acute non-lymphocytic leukemia (ANLL) and 1 case of chronic lymphocytic leukemia (CLL), and in 14 healthy children was detected by fluorescent quantitative polymerase chain reaction (FQ-PCR). Its clinical significance was analyzed according to the clinical manifestations, prednisone sensitivity test, and complete remission (CR) rate after induction chemotherapy. RESULTS: EBV DNA was detected in 8 (22.86%) of the 35 pediatric leukemia patients. The positive rate of EBV DNA was 26.92% (7/26) in ALL with quantity of (5.144+/-6.91)x10(5) copies/ml, and 12.5% (1/8) in ANLL patients with quantity of 4.031x10(3) copies/ml. No EBV DNA was detected in CLL patients and healthy controls. The occurrence rates of peripheral leukocytosis and hepatosplenomegaly were significantly higher in the patients with EBV infection than in the patients without EBV infection (P <0.001). In ALL, the rate of no response to prednisone was significantly higher in the patients with EBV infection than in the patients without EBV infection (100% vs. 26.32%, P =0.001); CR rate after induction chemotherapy was significantly lower in the patients with EBV infection than in the patients without EBV infection (28.57% vs. 84.21%, P=0.003). In ANLL, the differences of CR rate and relapse rate were not significant between the patients with and without EBV infection (P=0.5). CONCLUSIONS: Pediatric leukemia patients with EBV infection have higher incidence of peripheral leukocytosis and hepatosplenomegaly. ALL patients with EBV infection have poor prednisone response and low CR rate.

[Kinetics of polynuclear cells].

Polymorphonuclear leukocytosis and granulopenia in infectious diseases have been studied for several years, either by intravascular kinetics of the polymorphs labelled previously in vitro, or by isotopic labelling in vivo and autoradiography of the bone marrow, using medullary kinetic study of granulopoiesis. Polymorpho-nuclear leukocytosis is usually due to an increased production and a relative mobilisation of reserves. Leukopenia may be due to various mechanisms, but there does not seem to be any qualitative disorder of circulating polymorphonuclear leukocytes with corpuscular hyperdestruction nor any abnormalities of multiplication of the bone marrow nor of maturation. On the other hand, one frequently finds abnormalities of distribution between the marginal and circulating compartments, increased extracorpuscular destruction, reduction in production due to reduction in absolute number or differentiation of the granulopoietic parent cells.

[Involvement of infections in asthmatic attack: with special reference to changes in leukocytes and eosinophils].

Changes in leukocytes and eosinophils in 60 patients with non-infectious attack (NIA patients) were compared with those in 50 patients with infection-related attack (IRA patients). In 30 (50%) of the 60 NIA patients, eosinophilia without leukocytosis was observed on admission, and in 23 (76%) of these 30 patients eosinophilia disappeared within 2 weeks of admission. In 36 (72%) of the 50 IRA patients, leukocytosis without eosinophilia was observed on admission, and the periods from the onset of infection to admission were inversely correlated with leukocyte counts. In 22 eosinophilia patients among the 50 IRA patients, the periods from the onset of infection to admission were correlated with eosinophil counts for up to 40 days, and in 13 (76%) of 17 eosinophilia patients not receiving a long-term steroid therapy during admission, eosinophilia continued for more than 2 weeks even after anti-asthmatic and anti-infectious therapies. There was no significant difference in serum IgE levels between the two groups on admission. These results suggest that evaluations of leukocytes/eosinophils on admission and clinical courses are very useful in the management of asthmatic patients with or without bacterial infections.

Correction of canine cyclic hematopoiesis with recombinant human granulocyte colony-stimulating factor.

Canine cyclic hematopoiesis (CH) is an autosomal recessive disease of gray collie dogs that is characterized by neutropenic episodes at 14-day intervals. The biochemical basis for CH is not known but may involve a regulatory defect of the response to or production of a hematopoietic growth factor. Administration of recombinant human granulocyte colony-stimulating factor (rhG-CSF) to two CH and one normal dog caused a marked leukocytosis (greater than 50,000 WBCs) in all three dogs. The leukocytosis was due largely to a greater than tenfold increase in neutrophils. Less pronounced but significant elevations in monocytes occurred during G-CSF treatment. The elevated WBC count was maintained for more than 20 days in all three dogs, and two predicted neutropenic episodes were prevented in both CH dogs during rhG-CSF treatment. A decline in the WBC count occurred simultaneously in all three dogs during the last five treatment days and was presumably associated with the development of neutralizing antibodies to the heterologous rhG-CSF protein. Bone marrow evaluation indicated that the swings in the myeloid/erythroid progenitor cells that are characteristic of CH were eliminated by rhG-CSF treatment in both CH dogs. These results suggest that the regulatory defect in canine CH can be temporarily alleviated by treatment with rhG-CSF and point to the potential treatment of human cyclic neutropenia with this agent.

[Granulocyte functional characteristics of mice with transplanted tumors].

The Ehrlich ascitic carcinoma (EAC) growing subcutaneously in (CBA X C57B1)F1 mice was found to induce leukocytosis with the elevated number of mature granulocytes in the peripheral blood. At the same time depletion of the cell amount in the thymus and an increase of cells, especially granulocytic ones, in the spleen was observed. Granulocyte contamination of the ficoll-verografin gradient interphase was detected in mononuclear cells separated from tumour host blood. Simultaneously, expression of Fc G-receptors of granulocytes decreased in tumour-bearing mice. These data are discussed in terms of inhibitory effect of the EAC on granulocyte functions in the presence of paraneoplastic leukocytosis.

An ongoing surveillance study of persistent crying and hypotonic-hyporesponsive episodes following routine DTP immunization: a preliminary report.

Hypotonic-hyporesponsive episodes and persistent crying are specific complications of pertussis immunization. Hyperinsulinemia, hypoglycemia, and leukocytosis have been noted after pertussis vaccine administration in a murine model. Five children with hypotonic-hyporesponsive episodes and 6 children with persistent crying following DTP immunization were studied. The children were found to have leukocytosis acutely, similar to findings reported in children following routine DTP immunization. No abnormalities were noted in plasma insulin or serum glucose. Five of 6 children with persistent crying had severe local reactions, suggesting that localized inflammation may be a cause of persistent crying.

Acute inflammatory effects of intratracheally instilled Escherichia coli endotoxin and sonicated suspension of Haemophilus pleuropneumoniae in swine.

A single bolus of either Escherichia coli endotoxin, sonicated suspension of Haemophilus pleuropneumoniae, or pyrogen-free normal saline was intratracheally instilled in six week old specific-pathogen-free pigs. Pigs exposed to E. coli endotoxin developed fever, leukopenia followed by leukocytosis, and endotoxemia. Leukocytosis was the only clinical abnormality noted in pigs receiving the sonicated suspension of H. pleuropneumoniae. At one day postexposure, focal areas of atelectasis and consolidation were observed in the caudal lung lobes of animals receiving either E. coli endotoxin or the sonicated suspension of H. pleuropneumoniae. Lesions were characterized by a neutrophilic bronchitis and bronchiolitis with alveolitis in the surrounding tissue. Increased numbers of alveolar macrophages and evidence of phagocytosis were observed by light and electron microscopy. No clinical abnormalities or lesions were observed in animals receiving normal saline. Lesions typical of acute porcine Haemophilus pleuropneumonia were not produced by either E. coli endotoxin or sonicated suspension of H. pleuropneumoniae, indicating that multiple virulence factors are probably involved in lesion development.

Elevated blood neutrophil concentration in mania.

Total, differential, and absolute blood cell counts were compared in 66 untreated manics and 178 untreated schizophrenics. Mania was associated with significantly higher total leukocyte counts (p less than .001), accounted for by a significant increase (p less than .0001) in the number of neutrophils. There were no significant differences between the two groups in any other blood cell elements. Using normative values, manic patients had significantly higher frequencies of both leukocytosis (25.8% vs. 12.4%) and neutrophilia (34.8% vs. 12.4%) than the schizophrenic group. These data suggest a significant association between leukocytosis, neutrophilia, and mania.

[Clinical laboratory characteristics of croupous pneumonia in recent years (based on data from the N. I. Pirogov Institute (RNPISMP) for 1980-1984)].

The results from retrospective clinical-laboratory study of 110 patients are reported, discharged with the final clinical diagnosis--croupous pneumonia, from the clinics of internal secretion of the institute for the period 1980 to 1984 including. It was established that the disease has become, in the last several years, more frequent, affecting younger subjects, with a predomination of males; the cases with sudden onset, occurring in younger people, have been reduced. In 1/4 of the cases bilateral involvement of the lungs by the disease was observed but at the same time, only several segments were very often involved and not the whole lobe; in about 1/3 of the cases, pleura was also involved. No cases with leukopenia were reported and leukocytosis was established in about 2/3 of the patients; shifting to the left is a more frequent sign of the disease as compared with leukocytosis.

Suppression of T lymphocyte functions by human C3 fragments. I. Inhibition of human T cell proliferative responses by a kallikrein cleavage fragment of human iC3b.

Cleavage of human iC3b by kallikrein isolated from human plasma generates a fragment, C3d-K, which is capable of inhibiting mitogen-, antigen-, and alloantigen-induced T lymphocyte proliferation. Native C3, C3a, C3b, and C3c-K had no effect on lymphocyte proliferative responses. In addition to being a potent suppressor of mitogen- and antigen-induced proliferation, C3d-K is capable of inducing leukocytosis in both mice and rabbits. Intravenous injection of C3d-K, but not C3, C3a, C3b, or C3c-K, results in a twofold to threefold increase in the number of circulating leukocytes. Thus, C3d-K exhibits two apparently independent functions, namely suppression of T cell proliferation and leukocytosis. Cleavage of iC3b by kallikrein results in the production of only two fragments. The larger fragment, C3c-K, is 144,000 m.w. and has a chemical structure analogous to that of C3c obtained from the cleavage of C3 by trypsin or elastase. The smaller fragment, C3d-K, is 41,000 m.w. and contains the metastable binding site of C3. It is through this site located in the C3d region of the molecule that C3 attaches covalently to target cells. Analysis of the amino terminal region of C3d-K provided a sequence that fails to overlap with any sequence yet reported for other characterized C3 fragments, including C3d originally obtained from elastase digestion. A revised model of the C3 molecule is proposed, with locations of the C3e and C3d fragments assigned on the basis of chemical analyses.

[Chronobiological evaluation of leukocyte curves].

Experiments on 87 dogs were performed to study a trajectory of reactive leukocytosis in response to different stimulants. The studies were carried out daily throughout 14 days after stimulation. The trajectory was found to be typical and independent of the stimulant dose, quality, administration site, or the status and species of the animal. It is suggested that this trajectory should be taken into consideration while evaluating reactive leukocytosis.

Acute febrile neutrophilic dermatosis. Sweet's syndrome.

Acute febrile neutrophilic dermatosis (AFND) (Sweet's syndrome) is characterized by warm, erythematous plaques, accompanied by arthralgias, fever, and leukocytosis. A 53-year-old man was seen with chronic, recurrent, and unusually persistent AFND. The patient had a history of a gastrojejunostomy for peptic ulcer disease and had symptoms of the blind loop syndrome. Medical therapy for the blind loop syndrome failed to control his skin lesions, fever, or leukocytosis. His symptoms did respond to prednisone therapy, however. The relationship of AFND to the bowel bypass syndrome is discussed.
