Exocoelomic and amniotic fluids were obtained by selective puncture under ultrasound guidance in normal human pregnancies between 5 and 13 weeks of gestation. Evaluation of the protein patterns in the exocoelomic fluid showed qualitative and quantitative changes with advancing gestation. During the second month of gestation, three electrophoretic bands were found with mobility compatible with albumin, alpha 1-globulin and beta-globulin and composed of at least eight proteins including: pre-albumin, albumin, alpha-fetoprotein (alpha-FP), alpha 1-protease inhibitor, haptoglobin, ceruloplasmin, transferrin and immunoglobulin-G, as revealed by immunoblotting. Protein patterns obtained between 9 and 13 weeks were comparable in exocoelomic fluid and in maternal serum except for the presence of alpha-FP in the alpha 1-globulin band. At the same gestational age, protein electrophoresis of amniotic fluid revealed four bands corresponding to albumin, alpha-FP, haptoglobin and transferrin. Creatinine levels were significantly lower (P less than 0.01) in amniotic fluid than in exocoelomic fluid, and alpha-FP levels were similar in both exocoelomic and amniotic fluids. These results suggest that the exocoelomic fluid is a transudate of the maternal serum except for the presence of high levels of alpha-FP, that amniotic and exocoelomic cavities are separated by a non-permeable membrane and that the secondary yolk sac plays an important role in early protein synthesis and transfer.

The serum concentration of four acute phase reactant proteins (haptoglobin, sialic acid, alpha 1-antitripsin, ceruloplasmin) were determined in 160 patients with laryngeal cancer. In 50 cases treated by surgery serial determinations were performed. The control group included healthy persons and patients with non-neoplastic diseases. The levels of haptoglobin, alpha 1-antitripsin and sialic acid were significantly higher in cancer patients than in control group. The levels of ceruloplasmin reveals no statistically significant difference between particular groups of patients. The serum concentrations of haptoglobin, alpha 1-antitripsin and sialic acid correlated with the clinical status of cancer patients. We suggest that serial determination of certain acute phase reactant proteins may be useful as a prognostic acid in following patients with laryngeal carcinoma.

We have developed a modified solvent/detergent (S/D) treatment to inactivate viruses in human plasma using 1% w/w final concentration of tri(n-butyl) phosphate (TNBP) and Triton X-100 and an incubation period of 4 h at 30 degrees C. The procedure inactivates > or = 10(6) chimpanzee-infectious doses (CID50) of HBV, > or = 10(5) CID50 of HCV, and > or = 10(6.2) tissue culture infectious doses (TCID50) of HIV. After virus inactivation, eleven plasma batches were lyophilized and 12 batches were deep-frozen until further use. The batches were characterized by extensive laboratory tests including measurement of clotting factors I-XIII, von Willebrand factor, plasminogen, inhibitors of blood coagulation and fibrinolysis, and other clinically important plasma proteins. All parameters were determined before and after S/D treatment. Twelve conventional single donor plasma units served as control. There were no marked losses of activities of clotting factors, antithrombin III, protein C, plasminogen, and C1-esterase inhibitor due to treatment. After the S/D step, the levels of these parameters were within the normal range in all batches. The same holds true for total protein, immunoglobulins, albumin, complement factors C3 and C4, haptoglobin, hemopexin, caeruloplasmin, alpha 1-antitrypsin, and pH. Protein S and alpha 2-antiplasmin activities decreased by about 50% and were frequently found to be slightly below the lower limit of the respective normal range after treatment. The interindividual variations of all proteins analysed were significantly lower than in the single donor plasma units. The S/D procedure did not lead to increases of markers indicating activation of hemostasis.(ABSTRACT TRUNCATED AT 250 WORDS)

Immunological profile of 42 men working under exposure to chlorine for a period from 2 to 38 years was analysed. Toxicological analyses of air samples which were carried out for 20 years showed similar chlorine concentration ranging from 0.21 to 1.05 mg/m3. The number of B, T, and non-B, non-T lymphocytes was determined as well as the C3c, C4 complement components and proteins of acute phase reaction: alpha 1-acid-glycoprotein, haptoglobin and ceruloplasmin in the serum. Chronic exposure to chlorine produced a stimulating effect on the immune system, which was manifested by elevated IgA, IgD and IgM levels, the concentration of acute phase reaction proteins and increased number of B lymphocytes. The observed phenomenon had no influence on the antibacterial and anticancer immunity of the workers.

In a sample group of 92 women undergoing prenatal echo-guided transabdominal amniocentesis between the 12th and 23rd week of pregnancy the Authors analysed amniotic fluid and maternal serum using the recently developed method of high resolution protein electrophoresis in order to identify the presence of particular proteins in the amniotic fluid which are pathognomonic for a number of maternofetal pathologies. The results obtained in normal and pathological pregnancies or in the case of twins showed a marked dispersion in amniotic fluid of total protein concentrations depending on the period of gestation; in addition, albumin, alpha 1-antitrypsin, alpha 2-glycoprotein acid, alpha 2-macroglobulin and beta 2-protein were also found. Plasma levels of prealbumin, albumin, alpha 1-glycoprotein acid and IgG were slightly reduced, whereas there was a marked increase in ceruloplasmin, transferrin and fibrinogen; C3 and haptoglobin levels were normal. It is therefore possible to ascertain that amniotic fluid proteins analysed by high-resolution 15-band electrophoresis did not vary qualitatively or quantitatively until the 23rd week of gestation and in those cases of twin or pathological pregnancies examined no anomalous band was found in the protein electrophoresis of maternal serum or amniotic fluid which might prove useful in prenatal diagnosis.

The biological activities of the haptoglobin polymorphism are controlled by continuous DNA sequences coding for the HP alpha and Hp beta polypeptide chains and forming with a linked Hp related gene the haptoglobin gene complex on chromosome 16. Probably, this DNA domain originates from the gene family of the serine proteases after having lost the informations for the proteolytic functions. Instead of this, the haptoglobins have acquired other qualities, among them the hemoglobin binding capacity, inserted into the Hp beta chain. The Hp polymorphism is constituted by the evolutionary progressive DNA sequences for the Hp alpha chains, which probably have activation functions. The haptoglobins display immunoregulative abilities, which can be immunosuppressive by inhibition of the lymphocyte reactivity or immunoinductive by influencing the IgM biosynthesis, adapted to the functional requirements. In this field, Hp 2-2 has a stronger effect than the two other Hp types. Moreover, the haptoglobins inhibit the prostaglandin synthesis and protect against harmful oxidation processes. These qualities are based on the hemoglobin binding ability and can be realized by Hp 1-1 with the comparatively highest efficacy. Further on, the haptoglobins are protease inhibitors. Finally, Hp 2-2 is associated with higher albumin and ceruloplasmin serum levels than Hp 2-1 and Hp 1-1. Evidently, the haptoglobins are inserted into a widely ramified network of biological functions. The selective advantages and disadvantages of the Hp polymorphism are noticeable under pathological conditions in case of malignant tumors, inflammations, autoimmune diseases, allergic illness, affective psychoses and affective lability favouring addiction.

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.

In 71 patients with fever and bacteremia without complications, a prospective study of acute-phase reactants is done. Raises in haptoglobin, ceruloplasmin, alpha-1-antitrypsin, protein C, beta-2-microglobulin, IgA and ferritin serum levels, together with leucocytosis and GSR, were very significant when diagnosis was done. Fibronectin, sideremia and transferrin were lowered. After 3 and 6 days of treatment haptoglobins, alpha-1-antitrypsin, protein C, ferritin, leucocytosis and GSR are lowered, while immunoglobulins, sideremia, transferrin and fibronectin raised, the latter until normalization. Fibronectin as well as changes in iron metabolism were very reliable parameters of inflammation and favorable evolution.

An objective approach for monitoring the treatment of acute pulmonary exacerbation in cystic fibrosis was evaluated. Eleven biochemical markers of inflammation (erythrocyte sedimentation rate, neutrophil count, C-reactive protein, alpha-1 antitrypsin, haptoglobin, ceruloplasmin, fibronectin, alpha-1 glycoprotein, alpha-2 macroglobulin, C3, granulocyte elastase and anti-Pseudomonas IgG) were measured in blood serum and plasma from 46 cystic fibrosis patients with chronic Pseudomonas aeruginosa colonization before and after treatment. The overall outcome in each patient was evaluated by means of a pondered sum of clinical, chest X-ray and lung function scores. Biochemical markers were related to the overall clinical improvement: haptoglobin, ceruloplasmin, fibronectin and alpha-1 glycoprotein showed a good sensitivity (64-70%), specificity (60-70%) and positive predictive value (86-89%). Granulocyte elastase showed a similar sensitivity (67%) and positive predictive value (85%) but a lower specificity (33%). The negative predictive value was generally poor (32-39%). Our data suggest that the combined measurement of some markers of inflammation and of conventional clinical parameters, may help in evaluating the efficacy of anti-infective treatment in cystic fibrosis.

Eleven proteins (immunoglobulins IgG, IgA, IgM, orosomucoid, alpha 1-antiproteinase, haptoglobin, ceruloplasmin, C-reactive protein, transferrin, prealbumin and alpha 2-macroglobulin) in human serum were quantitated by a new microparticle-enhanced nephelometric immunoassay. This is a one step competitive assay, based on the nephelometric measurement of light scattered by clusters of protein-coated microparticles specially synthesized for that use. Statistical evaluation (precision, recovery and method comparison) shows that the determination of serum proteins is reliable and accurate for wide ranges of concentration and that the method is quite adequate for strongly increased concentrations. This microparticle-enhanced nephelometric immunoassay appears to offer an alternative method for routine measurement of a great variety of serum proteins at high and intermediate concentrations, which are usually quantified by radial immunodiffusion or conventional immunonephelometry. On account of its sensitivity, it can also be used for the determination of relatively low concentrations of analytes.
