Iron status was evaluated in 103 elderly institutionalized individuals using haemoglobin concentration, red cell indices, serum iron, serum transferrin, serum ferritin and basic red cell ferritin. Inflammatory processes were identified by measuring concentrations of orosomucoid and C-reactive protein in serum and leukocyte counts. Anaemia was present in 16.5% of the individuals. No serum ferritin values were in the range of depleted iron stores; however 6% of the elderly individuals presented basic red cell ferritin less than 3 attog/cell (3 x 10(-18) g/cell). Serum ferritin was positively correlated with markers of inflammation. Basic red cell ferritin measurement was not influenced by inflammation and may provide a reliable indicator of iron status in the elderly.

The serum and urinary ferritin levels in 52 RA patients were measured by the 2-site immunoradiometric assay method. Serum ferritin levels in RA patients correlated with C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) but not with serum iron levels and hemoglobin concentrations, although they were within the normal range. High serum ferritin levels were associated with sera with hyper gamma-globulin and rheumatoid factors. In sequential studies, serum ferritin changed in parallel with ESR, CRP and disease activity in a majority of the patients. The urinary ferritin levels and u/s ratios in some RA patients were higher than control values. Higher values were found particularly in the group of patients under gold therapy but not in groups under other treatments.

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.

This study was undertaken to gain insight into the mechanisms responsible for the hypoferremia occurring after severe exercise. To this end, 18 athletes who were competing in a 160-km triathlon involving canoeing, cycling, and running were evaluated before the race, immediately after the finish, and thereafter at 30 min, 24 h, and 48 h. The evaluation included plasma iron, total iron-binding capacity, lactoferrin, ferritin, haptoglobin, cortisol, various enzymes, and white cell count. The cortisol, white cell count, and lactoferrin were significantly increased immediately after the race, while the plasma iron and transferrin saturation were significantly decreased. There was a 40% but nonsignificant rise in the plasma ferritin at the completion of the race, while the C-reactive protein was raised by nearly 300% at 24 h. In contrast, haptoglobin declined significantly by 24 h but was normal again 24 h later. Quantitative considerations suggested that the lactoferrin was not responsible for removing transferrin iron from circulation and hence causing the hypoferremia. Instead, it seemed more likely that the iron-related changes were occurring as part of an acute phase response initiated by muscle injury.

The content of normal serum proteins, acute phase (C-reactive protein, pregnancy-associated alpha 2-glycoprotein) and tissue proteins (ferritin, nonspecific tissue esterase) was studied in the sputum of 256 patients with different pulmonary pathology, over time using immunochemical methods. Protein elimination with the sputum was shown to depend upon the nature and gravity of bronchitis and pulmonary destruction. Analysis of the qualitative composition of the sputum proteins and their content can be used in pulmonology for differential diagnosis and assessment of a course of pulmonary diseases.

To define the hematologic changes during a mild viral infection, 93 infants were immunized with live attenuated measles virus and studied prospectively at 0, 4, 9, 14, 21, and 30 days. Hemoglobin concentration decreased significantly by days 9 and 14. The decrease was greater than 1.0 g/dL in 8.6% and greater than 0.6 in 24.3% of the infants. Of the nonanemic infants, 22% became anemic. Serum iron and percentage saturation of transferrin decreased, whereas serum ferritin increased significantly. Mean cell volume, iron-binding capacity, protoporphyrin, and haptoglobin did not show changes. Reticulocyte index and erythropoietin increased significantly at 30 days. Leukocyte counts, Zetacrit, and C-reactive protein did not help to predict the hemoglobin decrease. These results suggest that a mild viral infection in infants induces a significant decrease in hemoglobin that may persist for 14 to 30 days and may be difficult to distinguish from iron deficiency.

The concentrations of tissue-polypeptide antigen (TPA), ferritin, alpha 1-acid glycoprotein (alpha 1-aGP), transthyretin (TBPA), alpha 1-antitrypsin (alpha 1-Pi), alpha 2-macroglobulin (alpha 2-MG), C-reactive protein and IgA were determined in broncho-alveolar lavage fluid of 13 patients with chronic bronchitis and 11 with bronchial carcinoma and accompanying bronchitis. Measurement of TPA, alpha 1-Pi, ferritin and transthyretin provides useful additional information in the diagnosis of bronchial carcinoma. The ratios of TPA/TBPA, alpha 1-Pi/TBPA and alpha 1-aGP/TBPA differentiate highly sensitively between bronchial carcinoma and chronic bronchitis.

The differentiation of bacterial from aseptic meningitis in postoperative neurosurgical patients has traditionally been based on the clinical setting, a recent history of steroid administration, and cerebrospinal fluid (CSF) studies, including the total and differential leukocyte counts, Gram stain, glucose, and total protein. Recent reports questioning both the validity of a relative CSF lymphocytosis in excluding bacterial meningitis and the usefulness of standard CSF testing prompted the authors to reevaluate these standard criteria. The type of operation, the presence of a foreign body, use of steroids, postoperative day on which symptoms developed, altered mental status, neck stiffness, headache, and nausea were not helpful in the differential diagnosis. High fever, new neurological deficits, an active CSF leak, and elevated leukocyte counts in the CSF and peripheral blood favored a bacterial etiology. The CSF glucose level and the differential leukocyte count were less helpful. No criterion or combination of criteria was sensitive and specific enough to reliably differentiate aseptic from bacterial meningitis in the majority of patients. The possibility of improving diagnostic accuracy with newer tests, such as CSF lactate, ferritin, total amino acids, C-reactive protein, and amyloid-A, should be assessed.

The nutritional status of an unselected group of 111 children from the village of Bouansa, People's Republic of the Congo, was studied. Comprehensive clinical examinations, anthropometrical measurements and analysis of albumin, prealbumin, ferritin, C-reactive protein (CRP), IgA, IgG, IgM, IgE, IgG- and IgM-circulating immune complexes (CIC) were carried out. The results show, by anthropometrical classification, a high prevalence of moderate malnutrition. Low levels of plasma proteins and high levels of immunoglobulins and CIC were found. No correlation between anthropometrical classification and plasma proteins was established. Children with increased levels of CRP showed low prealbumin values and increased levels of ferritin. Patterns of immunoglobulins and CIC were close to those found in other studies in tropical countries. To evaluate the anthropometrical and biochemical findings it is necessary to take into consideration the apparently healthy appearance of the children, which shows the degree of adaptation to the limited availability of food and the high rate of acute and chronic infections.

In order to discriminate between malignant and benign effusions, the values of carcinoembryonic antigen (CEA), ferritin, beta2-microglobulin (BMG), acid-soluble glycoprotein (ASP), tissue polypeptide antigen (TPA), adenosine deaminase (ADA), and immunosuppressive acidic protein (IAP) were measured in the pleural fluid of 54 patients with lung cancer, 20 with malignancies other than lung cancer, 18 with tuberculous pleurisy, and 22 with benign diseases other than tuberculosis. CEA levels in malignant effusions were significantly higher than those in benign effusions. At a cutoff level of 5 ng/ml, 68% of the patients with lung cancer and 44% of the patients with other malignancies showed elevated pleural fluid CEA levels. In 13 lung cancer cases with negative pleural fluid cytology, nine cases had elevated pleural fluid CEA levels. The mean pleural fluid BMG level of patients with benign diseases was significantly higher than that of patients with malignant diseases, but there was a marked overlap between those with malignant and benign diseases. No significant differences were found in the pleural fluid ferritin, ASP, TPA, and IAP levels between malignant and benign conditions. ASP and IAP pleural fluid levels showed significant correlations with the pleural fluid C-reactive protein (CRP) concentrations suggesting that they also reflect inflammatory activity. The mean ADA activity in tuberculous effusion was significantly higher than that resulting from other causes of pleural effusion.
