In 9 groups of liver diseases, 11 serum protein parameters were studied. Prealbumin, retinol-binding protein, albumin, alpha-lipoprotein and Normotest (NT) were usually highly intercorrelated and separated best among groups with different types of functional impairment. Haptoglobin, C3 and total iron-binding capacity were probably also sometimes reduced by restricted protein synthesis but appeared to be more easily affected by other factors, alpha1-antitrypsin was often increased in different liver diseases, but a pattern compatible with the "acute-phase reaction" was regularly present only in hepatic tumors. Bile retention was often accompanied by relatively high levels of ceruloplasmin, C3, and alpha-lipoprotein and by high NT values.

Analysis of 25 plasma proteins was performed on blood drawn from 7 females before and during treatment with danazol. This steroid was found to induce a pattern of plasma protein changes similar to but not identical with that of other 17 alpha-alkylated anabolic steroids. For comparison, the same 25 plasma proteins were analyzed in blood from pregnant women in their third trimester, when the estrogen influence on plasma protein synthesis is most pronounced. Five major types of response were found. 1) Albumin and orosomucoid were not influenced by danazol or, after correction for volume expansion, by pregnancy. 2) Prealbumin, C1-esterase inhibitor, and haptoglobins increased substantially during danazol treatment but were not significantly influenced by pregnancy. 3) Transferrin, antithrombin III, prothrombin, and plasminogen showed marked increases after administration of danazol and during pregnancy. 4) Transcortin, ceruloplasmin, and alpha 1-antitrypsin doubled in pregnancy but were not influenced by danazol. 5) The concentrations of T4-binding globulin, pregnancy zone protein, and sex hormone-binding globulin more than doubled in pregnancy, and all three decreased to one third or less on administration of danazol. The plasma estradiol content fell correspondingly. The different types of plasma protein response found in these two groups of patients fit the hypothesis that hepatocytes contain steroid receptors capable of reacting with estrogens and/or other steroids such as danazol and, thus, influence the biosynthetic rate of many but not all plasma proteins according to a specific pattern. The synthesis of some of the estrogen-sensitive proteins is depressed after intake of danazol, which suggests that there is a competition for the receptors in the hepatocytes as there is for other estrogen target tissues.

Thirty-nine women admitted to the Main Medical Center for biopsy of a lump in the breast has been followed sequentially for six months to determine whether a diagnostic profile of plasma protein changes occurs in early breast cancer, compared to non malignant breast disease, and whether plasma protein changes in breast cancer patients could be correlated with the spread of the tumor. Eighteen women had early operable breast cancer and twenty-one had benign breast disease. Each patient had 10 serum proteins measured preoperatively and post-operatively at three and six months. The patients with breast cancer had significantly higher levels of beta 2 glycoprotein preoperatively and ceruloplasmin at six months postoperatively than those with benign breast disease. There were a number of significant correlations between serum protein levels and the progression of breast cancer as measured by the clinical score. There were significant correlation with ceruloplasmin properatively and at three months postoperatively. Prealbumin and hemopexin showed correlations preoperatively: alpha 1 antitrypsin and beta 2 glycoprotein only correlated at three months postoperatively. Longer follow up will be required to establish the value of serum protein changes which could predict the development of metastases in patients with breast cancer.

Sixty women admitted to the King's College Hospital group for biopsy of a lump in the breast have been followed sequentially for one year. Thirty women had early operable breast cancer and 30 had benign breast disease. Each patient had 10 serum proteins measured preoperatively and postoperatively at three months and at one year. The patients with breast cancer had significantly higher levels of beta2 glycoprotein preoperatively and caeruloplasmin at one year postoperatively than those with benign breast disease. There were a number of significant correlations between serum protein levels and the progression of breast cancer as measured by the clinical score. There were significant correlations with caeruloplasmin preoperatively and at three months postoperatively. Prealbumin and haemopexin showed correlations preoperatively; alpha1 antitrypsin and beta2 glycoprotein only correlated at three months postoperatively. A longer follow-up will be required to establish the value of serum protein changes which could predict the development of metastases in patients with breast cancer.

In 92 patients with multiple myeloma and IgG monoclonal proteinemia concentrations of seventeen different serum proteins were specifically determined. Prealbumin, albumin, alpha, HS-glycoprotein, alpha-macroglobulin, transferrin and immunoglobulins IgA, IgM and IgD were significantly decreased in patients with IgG myeloma. On the contrary the means found for the typical acute phase proteins i.e. haptoglobin, orosomucoid and CRP were significantly elevated. No significant differences were demonstrated for less typical acute phase protients, i.e. alpha1-antitrypsin, ceruloplasmin and C3-component as well as for hemopexin and beta2-glycoprotein I. CRP values were strongly elevated in some sera, however in majority of patients they were within the normal limits. Negative correlation was found between monoclonal IgG and the most of the studied proteins inclusive immunoglobulins IgA, IgM and IgD. No correlation was demonstrated between the monoclonal IgG and the triad of typical acute phase proteins. Positive correlation was found between monoclonal IgG and the total serum protein and further among the proteins negatively correlated with monoclonal IgG as well as among the individual acute phase proteins. Explanation of the correlations reported has been suggested.

Due to the stress imposed by the process of bone marrow transplantation (BMT), we hypothesized that individuals receiving such a transplant underwent an acute phase response (APR). Circulating levels of C-reactive protein (CRP), haptoglobin (HAP), alpha-1 acid glycoprotein (AAG), ceruloplasmin (CER), zinc (Zn), copper (Cu), interleukin-6 (IL-6), albumin (ALB), and thyroxine-binding prealbumin (TBPA), were measured at baseline (Day -7), Day -4, Day 0 (Transplant Day), Day +2, +7, and weekly until day 28 in 14 adults receiving an autologous bone marrow transplant as Phase 1 treatment for various hematologic or solid tumor malignancies. Ten of 14 recipients survived, 9 of which had a significant increase in CRP (p = 0.012), HAP (p = 0.011), AAG (p = 0.002), and decrease in ALB (p = 0.002) and TBPA (p = 0.004) on Day +7, but not Day 0, after bone marrow reinfusion. These findings document the presence of an APR and suggest that the bone marrow transplant process (post reinfusion) initiates a stress response in the recipient.

116 women 21-36 years old, who had been taking oral contraceptives (OC) for at least 1 and 1/2 years and, at the most, for 4 years, were studied. The subjects underwent detailed clinical, biochemical, and immunological tests using samples of their blood sera. Their OC was Neogest consisting of .15 mg levonorgestrel and .03 mg ethinyl estradiol. Prealbumin values were higher than normal .40 g/l ) in 23 of 83 women studied. Alpha-1-antitrypsin values were below normal in 55 and above normal 4.0 g/l in 13 of 114 subjects studied. Alpha-2-macroglobulin was below normal (1.75 g/l) in 18 and above normal 4.20 g/l in 3 women of 67 studied. In 26 women, orosomucoid (alpha-1-glycoprotein) values were below normal (.55 g/l) and in 2 women the values were above normal (1.40 g/l) among 116 women. The ceruloplasmin values were below normal in 2 (.15 g/l) and above normal in 51 women (.60 g/l) of 115 studied. The effect of OCs on these proteins and possible metabolic changes and pathological associations were also addressed. All of these differences were statistically significant (p 0.01). The relationship of deviation from normal was the largest for alpha-1-antitrypsin with a below normal direction (1/1 = .482) and for ceruloplasmin with an above normal direction (1/1 = .440). The main reason of departure was the large number of above normal values in the case of prealbumin and ceruloplasmin and the large number of below normal values for alpha-1-antitrypsin, alpha-2-macroglobulin, and orosomucoid.

The authors present a system for the appraisal of the nutritional and inflammatory condition in patients suffering from cystic fibrosis (CF) in the phase of apparent inactivity of pulmonary infection, using a system of indices based on the quantification of some plasmatic proteins. The plasmatic appraisals of 4 visceral proteins (albumin, thyroxine-binding prealbumin, retinol-binding protein and transferrin) and, as well, of 5 proteins of the acute phase (alpha-1-acid glycoprotein, alpha-1-antitrypsin, alpha-2-macroglobulin, haptoglobin and ceruloplasmin) were obtained in a control group of 16 healthy children and in another of 14 children affected by CF. With the proteic plasmatic appraisals of the control group, the knowledge of their biological value and after a statistical-mathematical analysis, the most sensitive, specific and independent proteins were determined for evaluating the nutritional and inflammatory condition, obtaining two simple formulas which were denominated Nutritional-Inflammatory Prognostic Indices (NIPI) A and B (NIPI A = alpha-1-acid glycoprotein + haptoglobin/albumin + prealbumin; NIPI B = haptoglobin/albumin). From the analysis of the results, it can be deduced that the children with CF are affected by an inflammatory process, very probably infectious.

Prealbumin, albumin, alpha 1-antitrypsin, alpha 1-antichymotrypsin, ceruloplasmin, haptoglobin, transferrin, IgG, IgM and IgA were studied in blood serum of healthy donors and of patients with chronic alcoholism by means of cross immuno-electrophoresis and immunodiffusion. Only content of alpha 1-antitrypsin was distinctly altered in blood serum of the patients with alcoholism as compared with normal state, while individual variations in content of the proteins studied were considerably higher in blood serum of the patients. At the same time, distinct dissimilarity of the patterns studied was found between healthy donors and patients with chronic alcoholism when concentration ratios of some positively and negatively charged acute phase proteins were calculated (alpha 1-antitrypsin/albumin, haptoglobin/albumin, haptoglobin/transferrin).

Serum sex-hormone-binding globulin (SHBG), transferrin, prealbumin, retinol-binding protein, and ceruloplasmin concentrations were evaluated in 12 women with anorexia nervosa before and after weight gain and in 12 healthy women with normal weight. The serum SHBG concentrations were higher in patients with anorexia nervosa before weight gain than in control subjects and they returned to the normal range after weight gain. The changes of SHBG concentrations were not associated with any change in plasma testosterone, estradiol, or free thyroxin concentrations. The body mass index in our patients after weight gain was lower than in control subjects. Prealbumin, retinol-binding protein, ceruloplasmin, and transferrin in anorectic patients before weight gain did not differ from those of the control subjects and increased after weight gain. The changes of serum SHBG concentrations in patients with anorexia nervosa during weight gain make SHBG determination a reliable index of nutritional status in this type of eating disorder.
