Venous blood samples were obtained from 42 children hospitalized for the recurrent episode of scarlet fever: immediately after admission and toward the end of one week's hospitalisation, after a three-week period and at a later control after four months. The 14 specific proteins were simultaneously quantitated in the serum specimens using radial immunodiffusion on antibodyagar plates. Antistreptolysin O titres were also determined and compared with the corresponding immunoglobulin levels. However, the titres showed only minor differences in various stages of illness the course of which was mild and without complications. Serum levels of prealbumin, albumin, alpha2HS-glycoproetin, transferrin and beta 2-glycoprotein I were found decreased at the acute clinical stage. Of the "negative acute phase reactants" prealbumin proved to be the most expressive one. Of a triad of "positive reactants" the largest relative increments showed haptoglobin, its increase was twofold of orosomucoid and that threefold of ceruloplasmin. C-reactive protein was increased almost in two thirds of patients on admission, but normalized in all cases about the end of the first week of penicillin therapy. No significant changes were found for alpha 2-macroglobulin. We could demonstrate significant rise and fall of IgD concentration in serum together with IgG, IgA, and IgM, all manifested the peak values already after one week's hospitalisation. In the recurrent episode of scarlet fever IgA showed significantly minor increments compared with the first illness.

The evidence that the acute phase glycoproteins of plasma are synthesized by the liver parenchymal cells is critically examined, and is found to be inconclusive. Some evidence is cited which favors the reticulo-endothelial system (RES) in general, and Kupffer cells in particular, as the site of synthesis of these proteins: 1. The entire RES contains non-glycogenic periodic acid Schiff-positive substances. 2. The diseases which affect glycoprotein levels are also known to affect the function of the RES. 3. When the animal is subjected to stress, the RES function is initially depressed and then stimulated. A similar biphasic behavior is shown by plasma glycoprotein levels. 4. Adrenal cortico-steriods are the major regulators of the RES function and of the synthesis of acute phase proteins. Moreover, both are stimulated at low concentrations, and depressed at high concentrations of the hormone. Some of the glycoproteins of the acute phase (prothrombin, the third component of complement, haptoglobin, transferrin and ceruloplasmin) have defense-related functions. The others seem to participate in phenomena like detoxification, promotion of phagocytosis, wound healing, prevention of tissue injury by lysosomal enzymes, prevention of trauma and recovery from inflammation. It is proposed that the acute phase proteins, together with antibodies, form major components of the definse system, and the RES attempts to deal with injury by mobilization of increased amounts of these substances.

Several serum proteins, such as prealbumin, protease inhibitors, immunoglobulins, metalloproteins and inflammatory glycoproteins were determined in the sera of heavily burnt patients by radial immunodiffusion. An increase of acute phase reactant glycoproteins (orsomucoid, haptoglobin, haemopexin, C-reactive protein), C3-complement, immunoglobulins, prealbumin and of the protease inhibitors (a1-antitrypsin, a2-macroglobulin) was found. For some proteins, such as prealbumin, haemopexin, immunoglobulins, this increase was preceeded by a decrease on days 3 to 5 post-burn. The time course of the increase was variable, faster for some patients and slower for others: orosomucoid, C-reactive protein, C3-complement reached peak values between days 6 and 8; immunoglobulins and hemopexin decreased then towards normal values. No significant increase was found for ceruloplasmin, transferrin, beta2-glycoprotein, a2-SH glycoprotein and GC-globulin. It is proposed that the selective overproduction of the above mentioned proteins may be related to the stimulation of acute-phase reactant protein synthesis by the liver as a result of tissue breakdown produced by the circulating proteases and especially by elastases and collagenases as was shown previously (Miskulin et al., 1978; Moati et al., 1978a).

Plasma concentrations of various physiologically important proteins, including transferrin, ceruloplasmin, haptoglobin, transcortin, sex hormone-binding globulin, thyroxin-binding globulin, renin-substrate, fibrinogen, coagulation factors VII and VIII, antithrombin-III, plasminogen, prealbumin, albumin, retinol-binding protein, and lipoprotein fractions, were measured before treatment with oral contraceptives (OCs) and then again after 6 cycles of treatment to measure changes in the daily synthesis rate of 2 proteins, albumin and fibrinogen, under the influence of various OC formulations. Results are presented for 38 women using high-dose (50 mcg estrogen) preparations, 38 using low-dose (30 mcg estrogen preparations), and 20 using a continuous-dose progestagen-only minipill (30 mcg levonorgestrel). Most of the proteins measured showed significant alterations in women using the high-dose OCs. Changes with the lower dose product were less marked, and most proteins were unchanged in women using the minipill. (For example, synthesis rates of fibrinogen, mg/kg/day, for controls, high-, low-, and mini-dose subjects were: 24, 43, 28, and 25 respectively). Data from isotope studies indicated that synthetic estrogens act on liver synthesis and secretion rates for many plasma proteins; hence the clinical associations seen with OC use.

A study of the serum proteins pattern of 30 patients with primary liver cell carcinoma and 11 with amoebic liver abscess was carried out. When compared with controls significant differences were found for both conditions in the values of pre-albumin, transferrin, albumin, haptoglobin, alpha 2-macroglobulin, and alpha 2HS-glycoprotein. In the differential diagnosis of amoebic liver abscess and primary hepatic carcinoma, the estimation of albumin, alpha 1-acid glycoprotein, haptoglobin ceruloplasmin, alpha 2H2-glycoprotein and transferrin was found helpful.

Plasma concentrations of lipoprotein-lipids, apolipoprotein B (apoB) and of seven other proteins have been estimated serially in 27 patients up to three months following myocardial infarction. Results were compared with those from age- and sex-matched control subjects. At three months the mean total, low density lipoprotein (LDL) and high density lipoprotein (HDL) cholesterol concentrations were higher than those of the control subjects, whereas very low density lipoprotein (VLDL) cholesterol, total and VLDL triglyceride, and total and LDL apolipoprotein B concentrations were not significantly different. Relative to concentrations at three months total and LDL cholesterol and apolipoprotein B concentrations fell markedly, and a slight fall occurred in HDL cholesterol following infarction. VLDL cholesterol and total and VLDL triglyceride were decreased only on day one. Albumin and transferrin concentrations were higher and alpha 1-acid glycoprotein was lower at three months than in the control subjects; alpha 2-macroglobulin, caeruloplasmin, haptoglobin and immunoglobulin IgM were not significantly different. Following infarction albumin and transferrin fell, alpha 2-macroglobulin did not change, and alpha 1-acid glycoprotein, caeruloplasmin, haptoglobin and IgM rose. The changes in both lipids and protein are probably part of the general metabolic response to trauma.

Parallel determinations were made, of 10 individual serum proteins and of proteins in the bronchial secretion obtained by aspiration from 8 subjects that did not show manifest bronchopulmonary disease. By application of the formula suggested by Deuschl and Johansson it was found that 37 percent of IgG, 84,5 percent of IgA, 48,9 percent of transferrins, 15,2 percent of alpha-1-anti-trypsin and 11,3 percent of ceruloplasmin present in the bronchial secretion are synthetised in the bronchial mucosa itself, while the rest occur as a result of diffusion from the blood. Acid alpha-1-glycoprotein and haptoglobin from the bronchial secretion originate in the blood. IgM was evidenced in the bronchial aspirate in only 3 subjects, and alpha-2 macroglobulin was not found in any of the subjects.

A new case of analbuminaemia is described in a 6 month old child of algerian origin. The condition was discovered fortuitously, the clinical manifestations consisting only of slight oedema. Serum albumin concentration was 64 mg/l and its immunochemical behavior identical to that of normal albumin. The body react by an increase in the synthesis of globulins. In the propositus, levels of alpha, antitrypsin, caeruloplasmin, haptoglobin, jalpha2 macroglobulin, transferrin, immunoglobulin M were more than 3 times normal. Analysis of non-esterified fatty acids normally carried by albumin was normal. By contrast, it was shown that the presence of free bilirubin not bound to proteins was detected from 17 micronmol/l. Study of the family showed a normal distribution of albumin and globulins. The genetic origin seen in previously reported cases was confirmed by the co-sanguinity of the parents.

LP, a saline extract of exudate-derived rabbit granulocytes, shown to be free of endotoxin contamination by sensitive LAL assay, can elicit brisk acute-phase responses in the rabbit. Following a single large intravenous dose of LP (875 mce) there is a brisk fall in serum iron at 8 hr and marked elevations in concentrations of CxRP, haptoglobin, fibrinogen, and ceruloplasmin and a lesser rise in sialic acid in the blood at 24 hr, which return toward baseline to varying degrees by 48 hr. When the crude LP solution is fractionated by column chromatography on Sephadex G75, all detectable acute-phase mediating activity elutes in a fraction (pool C) which contains all the pyrogenic activity and about 15% of the total eluted protein. Within the limitations of the methods employed, the acute phase stimulating activity and the pyrogenic activity of LP preparations appear to be closely linked.

Numerous changes occur in the sera of patients bearing malignant neoplasms. These changes may take the form of appearance of oncofetal proteins that are normally not detectable in non-cancer-bearing patients, or an alteration in the normally present serum constituents such as the serum proteins. Monitoring of these serum factors may be of considerable value in assessing the progress of cancer patients following treatment of their primary tumour. This paper reviews progress in this area to date and documents our early results with six non-specific serum factors (total protein, total protein hexose, total protein hexosamine, ceruloplasmin, alpha-1-antitrypsin, and haptoglobin), in 64 patients bearing a variety of malignant neoplasms in various stages of the disease. Present methods of postoperative assessment of cancer patients are inadequate for detecting early recurrence. Preliminary results indicate that the nonspecific serum factors that we are studying may be of considerable value for monitoring of cancer patients, and may also possibly serve as a diagnostic screen in high-risk groups.
