Plasma fibronectin is regarded to play an important part in a decrease of the resistance to infections. To specify the role of fibronectin in the pathogenesis of infectious complications in patients with depressions of hemopoiesis, the content of this opsonin was measured by ELISA in 113 patients with different patterns of hemoblastoses, lymphoproliferative diseases and with an aplastic syndrome. In 42 patients, the concentration of opsonin was measured in the presence of the superimposed infection of varying gravity. The fibronectin content was examined in 39 patients before, during and after completion of the cytostatic polychemotherapy. It turned out that in patients with paraproteinemic hemoblastoses, lymphogranulomatosis, aplastic anemia, chronic lympholeukemia, acute lympho- and myelo(mono)blastic leukemias, cyclic neutropenia, chronic myelosis and hematosarcomas, the concentration of fibronectin remained normal in the absence of infections. The computation of the linear correlation ratio did not reveal any association between the opsonin level and the concentration of neoplastic elements in the peripheral blood. Repeated measurements of the fibronectin level in patients whose underlying disease ran its course in association with marked neoplastic fever failed to detect any deficiency of the glycoprotein. The lowering of the fibronectin level was recorded in patients with a grave concomitant infection of the type of sepsis, necrotic enteropathy and lobar pneumonia. The degree of opsonin deficiency correlated with the patients' disease gravity. Prolonged reduction in the blood fibronectin level was of unfavourable prognostic importance. Cytostatic polychemotherapy, myelotoxic agranulocytosis as well as infectious complications of low gravity did not influence the concentration of fibronectin.(ABSTRACT TRUNCATED AT 250 WORDS)

In a prospective randomized study of treatment for early-stage Hodgkin's disease presenting above the diaphragm, 76 patients had staging by laparotomy (Group I) and 28 had staging by closed techniques (Group II). Treatment consisted of involved-field radiotherapy alone (44 patients), involved-field radiotherapy followed by chemotherapy (38 patients), total nodal radiotherapy alone (15 patients), or total nodal radiotherapy followed by chemotherapy (seven patients). On presentation, both groups had similar clinical features and similar treatment distribution. With similar follow-up (87 months), no significant differences in remission or survival were observed between Groups I and II: remission 59 versus 68 percent; survival 74 versus 92 percent; p value 0.27 and 0.09, respectively. Multiple areas of relapse were more frequently observed in Group I (11 of 32 had relapse) as compared with Group II (none of nine had relapse, p less than 0.082). In Group I, relapse in the abdomen was observed as an isolated event or as part of disseminated relapse in 12 percent of patients compared with 3 percent (one patient) in Group II with abdominal relapse alone. Seven patients in Group I and two patients in Group II died with Hodgkin's disease. Six other patients in Group I died with complete remission of non-Hodgkin's lymphoma (one patient), leukoencephalopathy (one patient), sepsis during chemotherapy (two patients), myocardial infarction (one patient), and cerebrovascular accident (one patient). Three other patients in this group had other secondary malignancies successfully controlled (histiocytic lymphoma, squamous cell carcinoma of the cervix, and malignant schwannoma). No second primary lesions or death with complete remission were observed in Group II. Staging laparotomy with splenectomy in early-stage Hodgkin's disease did not improve the duration of remission or survival or decrease the number of abdominal relapses compared with closed staging.

The results of 111 children with Hodgkin's disease, who were treated with chemotherapy of different intensity and reduced radiotherapy (Cooperative Therapy Study HD 82, 12/81 - 9/83) are presented. There is no evidence that reduction of radiotherapy and selective splenectomy (splenectomy only in case of high probability of splenic involvement) induce a higher rate of relapses. All 87 patients with pathological stage I, II and IIIA are in first remission. 2 of 24 patients with stage IIIB/IV died of sepsis, 1 of those 24 patients relapsed. Splenectomy could be omitted in 2/3 of patients, in 75% of splenectomy splenic involvement was proved. 7% of all children get splenic irradiation.

Simultaneous combination chemotherapy (CT) (BCNU 40 mg/m2, procarbazine 50 mg/m2, prednisone 40 mg/m2, and vincristine 1.4 mg/m2) with low-dose radiation therapy [(RT) 2000 rad] delivered to all areas of tumor involvement aside from the bone marrow was given to 28 patients with advanced Hodgkin's disease. Upon completion of RT and CT, the BCNU and procarbazine was increased by 100% until a total of six cycles of CT (with and without RT) were given. Eleven patients had received prior CT and had not achieved complete remission (CR) or had relapse from CT-induced CR within 1 year. Seventeen others had not had prior CT (7 had prior RT). Among the previously treated patients, one patient died in autopsy-proven CR during treatment. The other 10 patients achieved CR. Eight had relapsed at 4-36 months (median time to relapse, 6 months). Five patients died of Hodgkin's disease, three others died of status asthmaticus and pneumonia, radiation pneumonitis, and acute nonlymphocytic leukemia, respectively. Three patients are still alive (2 in continuous CR) at 28, 89, and 90 months. Among the previously untreated patients, four died during treatment, one of acute myocardial infarction, two of liver failure, and one of radiation pneumonitis. Twelve of the other 13 patients achieved CR. One of the CR died of pneumonia and sepsis 3 months after completion of treatment; two other patients relapsed at 10 and 15 months. Nine remain in continuous CR at 42-89 months of follow-up, (median follow-up, 81 months). Of 107 tumor areas treated with RT, in-field relapse occurred in two areas (1.9%). Hematologic tolerance to this treatment was good in both groups of patients. Radiation pneumonitis occurred in 50% of the patients whose lungs were irradiated, and it was fatal in two. By design or for other reasons, the median and mean doses of BCNU and procarbazine given to previously treated patients were 62% and 65.2%, respectively. In untreated patients, the median and mean doses of these two agents were 66.6% and 61.4%, respectively. There were no differences in dosage of these two agents between patients who remain alive in CR and those who relapsed and died. The potential of similar programs of radiation and chemotherapy is discussed.

Between January 1978 and December 1982 successful sequential chromosome analyses were carried out on bone marrow cells of five patients previously treated for Hodgkin's lymphoma (HL) presenting unexplained cytopenia or pancytopenia during follow-up. All patients had concurrent morphological examination of bone marrow specimens showing signs of dysplasia and/or hypoplasia, without leukaemic infiltrate. Six other patients treated for HL who had normal haematological parameters served as controls. All the patients with unexplained cytopenias had clonal chromosome abnormalities; monosomy for chromosome No. 5 was the most frequent. No abnormalities were detected in the control group. Two patients have evolved to resistant leukaemia, one died of sepsis before leukaemic conversion while severely neutropenic, and two are in full marrow and cytogenetic recovery after aggressive anti-leukaemic treatment in the pre-leukaemic phase. Our data suggest that cytogenetic studies may be of crucial value in detecting therapy-induced preleukaemia (t-PL) at an early stage of its evolution and in planning appropriate therapy before the establishment of overt leukaemia.

This is a study of 234 children and young adult patients entered in the Intergroup Hodgkin's Disease in Childhood (stage I-II) Study from November 1975 to June 1981 and followed for a mean of 3.8 years after laparotomy. All patients had a staging laparotomy with total splenectomy, liver biopsy, and sampling of abdominal lymph node groups. Four patients (1.7%) have had documented sepsis, and three have had possible sepsis. There has been no sepsis-related death. Intestinal obstruction requiring operation was noted in four patients (no intestinal resection required). Urgent operation was necessary in two patients, one with ureteral obstruction and one with ovarian torsion, following a repositioning procedure, neither of these patients died. Organisms in the four patients with positive blood cultures were Streptococcus pneumoniae (two) and Haemophilus influenzae (two). Of the 234 patients in the study, 194 (83%) had received polyvalent pneumococcal vaccine, and 174 (74%) were taking prophylactic antibiotics. One of the two patients with pneumococcal sepsis had not been vaccinated, and the second was vaccinated only during radiotherapy. Only one of the four patients with positive blood cultures was on a prophylactic antibiotic treatment regimen at the time of the septic episode. The liabilities in employing laparotomy-splenectomy for the evaluation of pediatric patients with Hodgkin's disease include both general surgical complications and an increase in the risk of hyperacute infection, specifically related to encapsulated species. The latter appears to be modified to a major degree by current prophylactic measures or therapy.

In 1975-1982, autopsies of 201 patients dying with leukemias and other tumors of hemopoietic system revealed infectious complications in 68.6%, among them pneumonias in 46.8%, sepsis in 10.9%, and inflammatory-necrotic processes of the digestive tract in 19.4%. More frequent occurrence of infectious complications in acute leukemias (68-75%) as compared with chronic (61-70%), in lympholeukemias (70-75%) as compared with myeloleukemias (61-68%), and virus infections including generalized forms of herpes in lymphogranulomatosis (30.8%) was noted. The importance of immunodeficiency conditions and granulocytopenia in the development of infectious complications which were the immediate cause of death of 56.7% of those dying with leukemias and other tumors of the hemopoietic system is discussed. The increased role in the etiology of these complications of the opportunistic intestinal microflora frequently present in various associations and in combinations with other microbes and fungi is noted.

Between 1956 and 1981, 306 splenectomies for hematologic diseases were performed at the UCLA Medical Center. Of these operations, more than 75% were performed for therapeutic reasons to control anemia, thrombocytopenia, neutropenia, or painful symptoms of splenomegaly. Of the 65 patients who had idiopathic thrombocytopenic purpura, 77% showed an excellent response, and of the 39 patients who had hereditary spherocytosis, 90% responded. Other diseases with predictably good response rates were autoimmune hemolytic anemias, Felty's syndrome, and hairy cell leukemia. Forty patients with Hodgkin's disease had splenectomies for diagnostic purposes the last 10 years. The overall morbidity and mortality were 24% and 6%, respectively, the most common complications being pneumonia, wound infections, and local postoperative bleeding, and the most common cause of death being sepsis. The review supports the thesis that in carefully selected patients, therapeutic splenectomy can have desirable palliative effects and that diagnostic splenectomy has a sufficiently low risk to warrant its consideration in patients with Hodgkin's disease.

After staging splenectomy, the risk of overwhelming sepsis in patients with Hodgkin's disease reaches 21% in certain subgroups. Youth, recent splenectomy and vigorous chemoradiotherapy predispose patients to this complication. Because of its explosive course and its known microbiology, post-splenectomy sepsis is better suited to prevention than to treatment. Since immunisation prior to treatment produces good antibody responses, all patients with Hodgkin's disease should probably be vaccinated against encapsulated bacteria at least 10 days prior to the onset of therapy.

Three hundred ninety-three splenectomies were performed within the Charity Hospital system during the decade from 1969 through 1979. This number included 56 operations in children under 16 years of age, which formed the basis of this report of the risk of infection in young splenectomized patients and provided guidelines for the role of splenectomy under emergency and elective conditions. Eight episodes of serious infection were documented in four patients. There was only one case of overwhelming postsplenectomy infection which resulted in death, for a mortality rate of 1.8 percent (1 of 56 children) for death due to overwhelming postsplenectomy sepsis. It is emphasized, however, that the development of serious postsplenectomy sepsis in our series resulted in a 25 percent mortality rate. The risk of postsplenectomy sepsis is much greater in those individuals who are immunologically compromised, such as those who undergo staging splenectomy for Hodgkin's disease. If splenectomy is indicated for a hematologic disorder, it is wise to defer operation for as long as possible, especially if the acute episodes are self-limiting or mild. Rather than the promiscuous use of polyvalent serum and antibiotic therapy after splenectomy in children, it is recommended that parents be advised to bring the child to the hospital anytime an illness or fever develops that might require an immediate loading dose of an appropriate antibiotic. The role of subtotal splenectomy or hemisplenectomy merits consideration in staging Hodgkin's disease. Preoperative study of certain immunologic parameters may provide guidelines as to the proportion of individuals who may be vulnerable to overwhelming sepsis after splenectomy.
