To study the disease process in the brain in subacute sclerosing panencephalitis (SSPE), sequential changes in ferritin, creatine kinase (CK), and neopterin in the cerebrospinal fluid (CSF) of two patients with SSPE were compared with the changes in the clinical signs and symptoms and the findings by magnetic resonance imaging (MRI). On the basis of changes in various substances in the CSF, especially ferritin, CK and neopterin, we concluded that the high-intensity area in MRI might be evidence of local inflammation and the resulting cell damage. Ferritin, CK and neopterin seemed to be biochemical markers in patients with SSPE for detection of the extent of lesions, and their measurement may provide information useful for evaluation of the therapeutic response.

1. It has been suggested that the physiological consequences of strenuous exercise are analogous to those of the acute-phase response. 2. In 70 male and 20 female competitive distance runners, a marked, but transient, neutrophil leucocytosis occurred immediately after these athletes completed a standard (42 km) marathon race. Concomitant significant increases were noted in the plasma cortisol levels, creatine kinase activity, C-reactive protein level, total protein level and albumin level (P less than 0.01). 3. The plasma fibrinogen, C-reactive protein and total protein concentrations were markedly increased both 24 h and 48 h after exercise (P less than 0.01). The serum haptoglobin level was significantly decreased after exercise (P less than 0.01), and increased 48 h later (P less than 0.05). There was no change in the serum iron level, total iron-binding capacity, per cent saturation of transferrin and serum ferritin level. 4. A significant increase in interleukin-1-type activity was demonstrated immediately and 24 h after exercise (P less than 0.01). 5. It is concluded that the metabolic sequelae of sustained exercise are similar, but not analogous, to the acute-phase response, and interleukin-1, probably plays a significant role in linking the haematological and immunological changes observed after sustained strenuous exercise.

The usefulness of tumor-associated trypsin inhibitor (TATI) in the diagnosis of various solid tumors was compared to other tumor markers occurring in serum and urine (CEA, CA19-9, CA125, CA72-4, CA50, CA15-3, CA72-4, NSE, TPA, AFP, CK-BB and ferritin). TATI was particularly well suited for the diagnosis of tumors of the pancreas, ovary, oesophagus and bladder. For tumors of these organs TATI may be considered the marker of choice. TATI was also a good marker for distinguishing between disease with or without liver metastasis in cancer of the colon and the breast.

Plasma zinc, iron, copper, and selenium and selected blood proteins were measured in 66 men before (BHW) and after (AHW) a 5-d period of sustained physical and psychological stress called Hell Week. Recovery blood samples were obtained from 26 men 7 d after Hell Week. Dietary intakes were determined BHW and during Hell Week; zinc, iron, copper, and selenium intakes during Hell Week averaged 23.6 +/- 3.4 mg/d, 35.4 +/- 3.9 mg/d, 3.0 +/- 0.5 mg/d, and 92.5 +/- 26.7 micrograms/d, respectively. C-reactive protein was detected in only five subjects BHW and in all subjects AHW. Zinc, iron, selenium, and albumin decreased by 33%, 44%, 12%, and 9%, respectively, whereas ferritin, ceruloplasmin, and creatine kinase concentrations increased AHW by 59%, 8%, and 266%, respectively. Haptoglobin concentrations increased 57% in 30 subjects but decreased 32% in 23 subjects AHW. The biochemical changes were transitory because protein (except ferritin) and mineral concentrations were similar to BHW values 7 d after Hell Week. Hell Week induced changes characteristic of an acute-phase response in physically active men.

Serum levels of total sialic acid, carcinoembryonic antigen (CEA), ferritin, lactate dehydrogenase, and creatine phosphokinase were measured both in tumor drainage blood (axillary vein) and in peripheral blood obtained from 121 breast cancer patients during surgery. No significant differences between mean values in peripheral and tumor draining blood, between cancer patients and healthy controls, or between patients with or without axillary lymph node metastases were found for any of the markers. Both ferritin and CEA levels were higher in axillary and peripheral blood from patients with central breast cancer versus other sites but the difference was significant only for CEA (p less than 0.05). CEA levels were significantly higher (p less than 0.01) in patients with greater than 2 cm diameter carcinomas versus T1 stage patients in axillary but not in peripheral blood. When the cephalic vein was clamped before the axillary sample was taken, ferritin showed a significant increase (p less than 0.05). We conclude that measurement of sialic acid, CEA, and ferritin in axillary venous blood in breast cancer patients is not of clinical benefit, although further data are needed to clarify whether other advantages can be derived.

In a case-control study of 84 myocardial infarction patients and 84 population controls we investigated the association between iron status parameters and myocardial infarction during the acute phase and after six weeks. Immediately after the infarction mean ferritin levels were significantly higher, whereas iron levels and iron saturation of transferrin were significantly lower in cases than in controls. Six weeks after the infarction, serum iron levels were still significantly lower in cases than in controls. Neither serum ferritin levels nor serum iron levels did show a clear association with the size of the ischemic tissue damage as estimated by creatine phosphokinase levels. Our results indicate that serum ferritin and iron levels are influenced by the traumatic effects of the myocardial infarction. Possibly, these transient changes are an acute effect, as seen in infections. An increased uptake of iron in the reticulo-endothelial system for synthesis of ferritin, may account for the lowered serum iron level and the iron saturation of transferrin.

Eleven potential biochemical markers were measured in serum from 33 patients with malignant and 13 with benign colorectal disease: four isoenzymes (creatine kinase-BB, homoarginine-sensitive alkaline phosphatase, salivary-type amylase, and macro-creatine kinase type 2), five specific proteins (ferritin, alpha 1-acid glycoprotein, C-reactive protein, alpha 1-antitrypsin, and ceruloplasmin), one oncofetal antigen (carcinoembryonic antigen, CEA), and one hormone (beta human choriogonadotropin). The sensitivity of individual markers for the detection of early-stage malignancy (n = 11) ranged from 0% to 64% (CEA 18%); for late-stage colon malignancy (n = 12) from 8% to 83% (CEA 83%). Specificity in patients (n = 10) with benign intestinal disease ranged from 80% to 100% (CEA 100%). The five most-sensitive markers--C-reactive protein, alpha 1-glycoprotein, CEA, macrocreatine kinase type 2, and homoarginine-sensitive alkaline phosphatase--were selected for use as a "colon panel." In retrospective comparison, use of the colon panel instead of CEA alone increased sensitivity by 17% and 64% for late-and early-stage cancer, respectively; specificity, however, decreased by 30%, but should improve with serial testing.

Many biological substances are commonly used as markers for malignant neoplasms, but no single marker with high specificity and sensitivity has been found for cancer to date. In this study we evaluated simultaneously the serum levels of five biomarkers of malignancy: phosphohexose-isomerase (PHI), creatine kinase isoenzyme BB (CK-BB), alpha 1-acid glycoprotein (AAG), beta 2-microglobulin (BMG), and ferritin. In 89 female patients with breast lesions, we identified 30 benign lesions, 32 primary breast cancers, and 27 metastatic breast cancers (pulmonary and/or bone metastases). Each marker was assayed individually and in a combination and was compared with other markers. The results revealed that in benign lesions only 7% had PHI values higher than our cut-off limit value, while 3% had elevated values of AAG, BMG, and ferritin. In primary breast cancer we discovered pathological values of CK-BB and AAG in 71%, of PHI in 69%, of BMG in 50%, and of ferritin in 47%. Metastatic disease was associated with elevated values in 88% of CK-BB, in 70% of PHI and AAG, and in only 55% of BMG and ferritin. Combined pathological values for primary and metastatic breast cancer were 79% for CK-BB, 71% for AAG, 70% for PHI, and only 55% for BMG and ferritin. These data were assessed by the Student t test, which revealed for each marker a significant capacity (P less than 0.01) to discriminate between benign lesions and neoplastic diseases. The same capacity to distinguish between primary and metastatic cancer was obtained by the simultaneous use of three markers (CK-BB, PHI, and AAG).(ABSTRACT TRUNCATED AT 250 WORDS)

Polycationic derivatives of ferritin containing primary amino groups (CFah) or tertiary amino groups (CFdmp) were potent platelet agonists inducing shape change, aggregation and secretion, but also agglutination in the presence of EDTA. Pretreatment of platelets with neuraminidase, PGE1, indomethacin, or creatine kinase/creatine phosphate inhibited CF-induced activation. In contrast, neuraminidase and PGE1 increased the agglutination by CF, indicating an inverse relationship between activation and CF-induced agglutination. At pH 7.4, the cationic charges of CFdmp exceeded those of CFah by a factor of 1.5 and the platelets bound approximately 1.5 times more CFah than CFdmp, suggesting the same number of anionic surface sites for both CF preparations. The capacity of the platelets to bind CF was diminished by 55% at 0 degree C or by 62% after aldehyde fixation and by 13% with PGE1. This suggests that the binding capacity depends on the mobility of the binding sites in the plane of the membrane but is only slightly increased by platelet activation. Binding to fixed or cold platelets approached equilibrium within a few seconds whereas saturation required several minutes at 37 degrees C. Neuraminidase preferentially reduced the slow binding and much less the rapid binding. Since activation by CF developed during seconds, suppressible by a brief treatment with neuraminidase 25 mU/ml, a small portion of neuraminidase-sensitive sites appears to be necessary for CF-induced platelet activation. Full activation and agglutination occurred at CF concentrations far below saturating concentrations. The results show that neither CF-induced activation nor agglutination depend on a simple neutralization of the negative surface charge.

Concentrations of total serum N-acetyl-neuraminic acid, carcinoembryonic antigen, ferritin, lactate dehydrogenase, creatine phosphokinase and total proteins were measured in both tumor drainage blood (axillary vein) and in peripheral blood taken during surgery from 44 breast cancer patients. There were no significant differences in any of the markers between mean values in peripheral and tumor drainage blood, between cancer patients and healthy controls, between patients with or without axillary lymph node metastases, or according to the site of breast mass.
