Radioiodinated fibrinogen distribution in cancer patients.

The usefulness of radioiodinated fibrinogen in tumor localization and of coagulation in 80 cancer patients was investigated. Tumors externally detected demonstrated positive localization in 63% of all cases and in 100% of osteosarcomas of limbs. Fibrinogen half-life was reduced in cancer patients particularly in cases with lymphoma, Hodgkin's disease and osteosarcoma irrespectively of basal plasma fibrinogen levels. In lymphoma and ovarian cancer, fibrinogen degradation products were correlated to radiofibrinogen T/2 reduction. In patients with the lowest fibrinogen T/2 and platelet count, heparin infusion therapy returned the fibrinogen half-life to normal range. Present results suggest the existence of enhanced coagulation both inside and around the tumor and/or dissemination in early cancer as well as in the more advanced stage.

Acute reactive stage proteins in gynaecologic cancers.

The authors report the plasmatic variations of ARPS (acute reactive proteins stage) in fifty eight women, admitted to the Obstetric and Gynaecological Clinic of Padua's University in the years 1978-1979 aged between 35 and 80 years old; those patients were affected by different types of gynaecological neoplasms: twenty three had cervical cancer, eight endometrial cancer, twenty six ovarian cancer. An evident increase was seen in the ARPS in the patients studied. In particular there was an increase in he haptoglobin in the ovarian cancer patients as well as an increase in the alpha-1 antitrypsin in the cervical cancer patients. Regarding ARPS and the clinical stage of the tumour the variations were important between T0 and T1 that is between tumours localized in the affected organ and those outside the primitive site but always in the pelvis. No evident alterations were found between T1 or T2; there was no other increase in the ARPS in neoplasm outside the pelvis.

Complement fixing antibody to varicella-zoster virus in cancerous patients.

The titer of complement fixing antibody to Varicella-Zoster virus was studied in sera from 161 cancerous patients and 161 healthy controls. Sera with antibody titers greater than or equal to 1/4 were 74 (45.9%) among cancerous patients and 120 (74.5%) among healthy controls. The difference between these two groups is statistically significant.

Relationship between Hb and HbA2 concentrations in beta-thalassemia trait and effect of iron deficiency anaemia.

The relationship of HbA2 to total Hb has been measured in 204 cases of Beta-Thalassaemia (beta-th-t) where the total Hb varied from 3.6 to 16 g/100 ml. The variation of total Hb in the study population was due, as far as could be defined, only to beta-th-t and a superimposed iron deficiency anaemia (IDA). Superimposed IDA decreases HbA2 proportionately more than it does total Hb (P less than 0.001). A not previously described relationship between HbA2 and total Hb was demonstrated and probably conformed to a second degree parabola.

Relationship between Hb and HbA2 concentrations in untreated and Fe-treated iron deficiency anaemia.

The absolute concentrations of Hb (x) and HbA2 (y) were statistically correlated (a = 0.0208; b = 0.0170; r = 0.4700; P less than 0.05) in 29 subjects with iron deficiency anaemia. 15 days after a month course of iron therapy the mean percentage increase of HbA2 was greater (123.9%) than that of Hb (62.0%). HbA2 concentration was still correlated with that of Hb (r = 0.6632; P less than 0.001), but the values for intercept and slope (a = - 0.1476; b = 0.0383) indicated a relatively greater production of HbA2.

Relationship between Hb and HbA2 concentrations in healthy and iron deficient subjects.

In 23 healthy subjects and in 115 patients with various degrees of chronic iron deficiency anaemia without congenital abnormalities of globin synthesis, Hb ranged from 3.4 to 16.3 g/100 ml. HbA2 ranged from 0.0550 to 0.5250 g/100 ml. Hb and HbA2 were statistically correlated, as shown by linear regression analysis (a equals --0.1387; b equals 0.0372; r equals 0.8198; P smaller than 0.001). The second degree parabola was not statistically different, but it gave a biologically preferable Figure for intercept (a equals --0.0006; b equals 0.0070; c equals 0.0015; r equals 0.8324; P smaller than 0.001). The second degree parabola was to be preferred also on the basis of previous literature results. Shortness of iron seems to reduce more the HbA2 than the Hb levels.

Desferrioxamine B: reversible side effects of high daily doses.

16 patients with chronic liver or haematologic diseases were parenterally given various doses of Desferrioxamine B (DF). Each daily dose of DF (from 1 to 4 g) was given for a 7 days cycle. Liver, kidney and blood functions were investigated at the first and seventh day of each cycle, and 1 and 2 weeks after therapy was stopped. 1 g/day and 2 g/day had no side effects, with the exception of a fall of white blood cell (WBC) count in a single case on 2 g/day. 3 g/day (15 patients) were followed by rises of blood urea, creatinine, alkaline phosphatase and glutamyl-transpeptidase respectively in 4 cases, and by falls of WBC count in 3 cases. 4 g/day (9 patients) caused rises of creatinine, GPT and GOT (1 case) or LDH (1 case), while WBC count dropped in 4 cases. All changes were reversible within one-two weeks. These recorded changes were outside the range of pretreatment values as obtained over the previous four weeks.

Electroimmunoassay of plasma subunits-a and -s in a case of congenital fibrin stabilizing factor deficiency.

Antigenic material related to the fibrin stabilizing factor (Factor XIII-FSF) has been found in all the examined patients with congenital deficiency, albeit in reduced amount. Recently, Bohn et al. (1973) showed that plasma Factor-XIII is composed by two subunits, A (or a) and S (or b); the former active protein, the latter probably FSF-vinding protein. Using specific anti-S and anti-A antisera the Authors found, in a case of congenital deficiency of factor XIII, absence of subunit A. Subunit S presented abnormal behaviour as demonstrated by means of quantitative immunoelectrophoresis according to Laurell.
