Serum albumin

The large mass of data that has been collected demonstrates that albumin distribution has a fairly constant ratio in many disease states, and that the extravascular pool appears to maintain the intravascular content by supplying albumin. The distribution of extravascular albumin may play some role in osmotic regulation of albumin synthesis. The skin is the major source of extravascular albumin. Factors influencing albumin production are state of health, environment, nutrition, hormonal balance, and osmotic equilibrium. Of these, the nutritional status is probably the most important. Sites of degradation of albumin are unknown. Stress and some hormones appear to enhance degradation. Metabolism of another protein does not affect albumin degradation, and albumin degradation and synthesis are not interdependent.     

Serum albumin

The liver manufactures albumin at a massive rate and decreases production in times of environmental, nutritional, toxic and trauma stress. Osmotic pressure is a basic evolutionary regulatory factor, and hormonal control over albumin production has been demonstrated. Where and why new or old albumin is degraded are questions which have not been clarified, although the vascular endothelium may well be the degradative site. Albumin is important as a transport protein, as a measure of evolution and as a model to study secretion following synthesis without the intervening steps of glycosylation. Investigations as to how this protein enters the endoplasmic membrane may well answer some of the questions concerning signal peptide insertion (288). The role of the urea cycle intermediate ornithine and its participation in polyamine synthesis, which has a positive effect on albumin synthesis, is under study. Likewise, the inverse relation between acute-phase protein synthesis and albumin synthesis regulated by interleukin 1 and other cytokines will merit further study. These are a few of the concepts which will be tested in the future.     

Serum thrombomodulin

Objective. Soluble thrombomodulin (sTM), a proposed serum marker of endothelial cell injury, was investigated as a parameter of disease activity in patients with systemic lupus erythematosus (SLE). Methods. Levels of sTM were determined by enzyme-linked immunosorbent assay. Disease activity was assessed using 3 established scoring systems: the American College of Rheumatology (ACR), the New York Hospital for Special Surgery (NYHSS), and the Systemic Lupus Activity Measure (SLAM) systems. Results. A close correlation was found between sTM levels and disease activity as assessed with all 3 scoring systems: r = 0.52 by the ACR, 0.75 by the NYHSS, and 0.82 by the SLAM. Conclusion. We found that sTM is a sensitive serologic marker of organ involvement in patients with SLE. Furthermore, sTM may prove to be an important marker for vasculitis in general.     

Serum ferritin

PURPOSE: There is increasing evidence that screening for colorectal cancer may save lives, and consequently, both professional and public interest in screening for colorectal cancer is increasing. As yet, however, there is no perfect screening test. Insidious blood loss is a common feature of colorectal cancer and may lead to a fall in serum ferritin before the patient becomes anemic. Measurement of serum ferritin, which is widely available and easily and inexpensively performed, has, therefore, been postulated as a potential screening test for colorectal cancer. METHOD: This study used samples of serum collected from 148 patients recruited to a screening study for colorectal cancer. All patients were thoroughly investigated by double-contrast barium enema and/or colonoscopy. Patients were selected randomly from each of three clinical diagnostic groups: 50 patients with proven colorectal cancer, 49 patients without colon disease, and patients with adenomas of the colon. Serum ferritin was assayed by immunoradiometry. The expected adult reference range is 25 to 350 µg/l, and results were reported without patient identification. RESULTS: There were no significant differences in serum ferritin levels among any of the three groups. CONCLUSION: Serum ferritin is unlikely to be of value as a screening test for colorectal cancer.
