The zone immunoelectrophoresis assay (ZIA) for C-reactive protein (CRP) determinations is easy to perform and requires only small amount of antiserum, e.g., 25-100 and 0.5-1.0 microliter anti-CRP antibody/20 serum and CSF samples, respectively. For quantitating CSF-CRP the immunoprecipitates formed were stained using alkaline phosphatase-conjugated secondary antibodies and the lowest standard concentration used was 30 micrograms/l. The immunoprecipitates formed when measuring CRP in serum were stained by Coomasie brilliant blue R250 with a detection limit of about 300 micrograms/l. CRP was determined in cerebrospinal fluid in 27 patients with bacterial meningitis (range less than 0.03-23.0 mg/l) and in 25 patients with viral meningitis (range less than 0.03-0.23 mg/l). CRP was quantitated in 52 sera by both the CRP ZIA method (y) and by electroimmunoassay (x). The correlation coefficient was r = 0.992 with the regression line y = 1.024 x + 0.855.

To detect antigens in the plasma of pregnant women that were not found in nonpregnant untreated normal women or males, highly sensitive immunodiffusion techniques with hyperimmune rabbit antiserum were used. The number of pregnancy-associated plasma constituents increased as pregnancy progressed in the 165 patients studied, with all 4 constituents usually seen in the third trimester. The 60 males and 111 nonpregnant women studied did not show any of these antigens. There were significant differences between second and third trimester reactions. (p less than .001). None of the antigens represented human chorionic gonadotropin, human placental lactogen, oxytocin, C-reactive protein, oxytocinase, alkaline phosphatase, or esterase. One of these constituents is present during combined estrogen-progesterone therapy.

A patient with pyoderma gangrenosum without associated disease was studied. Routine investigations showed several abnormalities. High ESR, high alkaline phosphatase and glutamyl transferase (gamma-GT) levels, low iron and iron binding capacity, altered protein spectrum, presence of Staphylococcus aureus and group G hemolytic streptococci in ulcer culture, higher than normal antistreptolysin titers in the serum, and perivascular infiltration in the skin. Biochemical investigations aimed at finding any excessive hydrolytic activity did not reveal the presence of neutral proteases in circulation leaked out from PMN-leukocytes or elsewhere. Lysozyme levels were higher than normal, amylase and lipase levels were normal and 5' nucleotidase levels were below normal range. TCA-soluble polypeptides were present in the serum at levels two times higher than those in normal individuals. Immunochemical investigations showed the absence of immune complexes in the serum but presence of high amounts of C-reactive protein. Total complement activity was higher than normal and so was C3c level. Clq, C4, and C3d levels were within normal range. Biologic studies showed the presence of a factor in patient serum that made guinea pig skin hard, painful, erythematous, and eventually hairless, but not necrotic. A similar factor was either absent in normal serum or present in very low concentration. After salazopyrine treatment, all the above mentioned abnormalities corrected except that 5' nucleotidase activity remained slightly lower than normal, alkaline phosphatase levels remained slightly higher than normal, and C-reactive protein levels remained very high, though lower than those during intense disease activity.

The diagnostic value of 7 laboratory parameters for the detection of metastases was investigated in 136 patients with verified breast carcinoma after mastectomy. The post-operative interval was 6 to 80 months (means = 27.5). 61 patients had multiple metastases as determined by physical examination, X-rays, computertomography, sonographic and scan procedures, while the other 75 patients had no evidence of metastases. Carcinoembryonic antigen (CEA), alkaline phosphatase (AP) and lactate dehydrogenase (LDH) proved to be reliable parameters for the presence of metastases; the combination of these 3 parameters had a sensitivity of 73.0% and a specificity of 94.7% in the detection of metastases. The additional determination of gamma-glutamyltranspeptidase (gamma-GT), blood sedimentation rate (BSR), C-reactive protein (CRP) and serum iron (Fe) increased the sensitivity of metastases detection to 83.8%, but the specificity decreased to 46.2%.

Peripheral blood specimens were obtained from 50 patients with various stages of breast cancer (I-II = 7, III = 6, IV = 24, treated and NED = 13), and 20 biochemical tests were performed. There are significant differences of hemoglobin, LDH, SGPT, serum protein, albumin, and alpha globulin values between patients with early (I, II, NED) and late (III, IV) lesions. Among patients with stage IV diseases, those patients with bony metastases had significantly higher values of alkaline phosphatase, alpha-1 globulin, IgA, and C-reactive protein than those with nonosseous lesions. Neither CEA nor pregnancy-associated alpha-2 glycoprotein showed any correlation with different stages or sites of breast cancer in these small series of patients.

A new sensitive assay for the calcium-dependent binding of rabbit C-reactive protein to phosphorylcholine has been developed. The assay involves coating the wells of polyvinylchloride microtiter plates with a bovine serum albumin-phosphorylcholine conjugate followed by the addition of C-reactive protein. The quantity of C-reactive protein is determined by indirect enzyme-linked immunoadsorbent assay using first, affinity purified goat anti-C-reactive protein immunoglobulin followed by a commercial rabbit anti-goat immunoglobulin-alkaline phosphatase conjugate. The binding of rabbit C-reactive protein to the bovine serum albumin-phosphorylcholine conjugate is completely inhibited by free phosphorylcholine, by pneumococcal C-polysaccharide and by calcium chelators but not by high concentrations of neutral, cationic or zwitterionic detergents. The assay is sensitive to 2 ng C-reactive protein.

Osteocalcin is a vitamin K-dependent bone protein synthesized by osteoblasts. In generalized bone disorders serum osteocalcin correlates with osteoblast activity. Bone resorption and new bone formation occur in chronic osteomyelitis, dependent on the level of inflammatory activity. In 17 patients with active chronic osteomyelitis undergoing surgery, the serum levels of osteocalcin, alkaline phosphatase and C-reactive protein were measured before and after treatment. The osteocalcin levels were within the normal range preoperatively (10.8 +/- 11.0 micrograms/l), in the early postoperative period, and at discharge. It is therefore not a helpful marker in the clinical management of this condition.

The occurrence of hepatosplenic candidiasis following prolonged neutropenic periods has emerged as a major problem for patients with leukemia. In order to evaluate the diagnostic value of various available procedures, we analyzed our findings regarding 26 leukemic patients with hepatosplenic candidiasis. A significantly increased level (> 50 mg/L) of serum C-reactive protein (S-CRP) was significantly more common than a daily fever (for which the mean temperature peak was > 37.5 degrees C) or raised levels of liver enzymes (serum alanine transferase, aspartate transferase, or alkaline phosphatase). Focal changes in the liver, spleen, or kidneys were detected in > 90% of the patients examined by computed tomography (CT) but in < 50% of those examined by ultrasonography. Seventeen diagnoses were based on the findings from microscopy of samples obtained invasively, whereas a positive fungal culture was the basis of the diagnosis for only five patients. In conclusion, monitoring the S-CRP level after a patient's recovery from neutropenia is useful in that its elevation is cause for early suspicion of hepatosplenic candidiasis. In detection of the hepatosplenic foci, CT is superior to ultrasonography. For establishing the specific diagnosis, aggressive collection of samples for microscopy is essential.

Phospholipase A2 (PLA2) modifications were investigated in patients with acute and chronic liver diseases, PLA2 variations were related to indices of liver function as well as to parameters of the acute phase response. Serum PLA2 activity modifications were fluorimetrically measured in 105 patients affected by acute and chronic liver diseases or extra-hepatic diseases. One-way ANOVA demonstrated a significant difference among groups (F = 4.53, P < 0.001); Bonferroni's test for pairwise comparisons showed that patients with hepatocellular carcinoma had higher mean values than subjects with benign extra-hepatic diseases (P < 0.01) and mild chronic liver disease (P < 0.05). Multiple regression analysis, performed choosing PLA2 as the dependent variable and blood urea nitrogen, C-reactive protein, alkaline phosphatase and alpha 1-fetoprotein as predictor variables was significant (multiple R = 0.7056, multiple R2 = 0.4978, F = 15.36, P = < 0.0001). The standardized regression coefficients found to be significant were those of C-reactive protein, blood urea nitrogen and alpha 1-fetoprotein. In conclusion, in patients with chronic liver disease, serum PLA2 activity increases parallel to disease severity and accompanies the expression of proteins of the acute phase response that, like PLA2 activity, increase in serum while liver synthesis declines.

A 61-year-old man became ill with a fever of 39.4 degrees C, decreased exercise tolerance and headache as well as chest pain. Physical examination 3 weeks after the onset of symptoms merely revealed irregular heart rate at 100 beats/min. Erythrocyte sedimentation rate was increased (30/61 mm), as were serum bilirubin, lactate dehydrogenase, alkaline phosphatase, gamma-GT and C-reactive protein. The ECG showed atrial fibrillation with a rapid and irregular ventricular rate, as well as ventricular extrasystoles (Lown type IIIA), there were no abnormal findings on either the chest radiography or transthoracic echocardiography. Antiarrhythmic treatment brought about atrial flutter with 4:1 a-v conduction. Transoesophageal echocardiography now revealed vegetation on the pulmonary valve and microthrombi in the left atrial appendage. Ten days after starting intravenous penicillin G (10 mega units four times daily), gentamycin (60 mg three times daily) and heparin (30,000 units over 24 h) sinus rhythm was restored, the vegetation had got smaller and no thrombi were demonstrated. After 27 days antibiotic treatment was changed to oral penicillin V. After 4 weeks the patient was discharged symptom-free.
