Creatine kinase isoenzyme (CK-BB) by RIA as a follow-up marker in stage D cancer of the prostate: comparison with PAP RIA

Fifty-nine patients with stage D carcinoma of the prostate under different modalities of treatment were studied for creatine phosphokinase isoenzyme BB (CK-BB) and prostatic acid phosphatase (PAP) levels in serum by radioimmunoassay (RIA) technique, in order to study the possible use of CK-BB as a follow-up marker compared to PAP. Thirty-three patients were in stable, 19 in progressive, and seven in regressive clinical state. CK-BB was above normal level in 52 (88%) out of 59 patients with no statistically significant difference between the three clinical states. On the other hand, PAP was above normal level in only 23 patients (38.98%) with statistically significant difference between the three clinical states (P less than 0.001). The PAP/CK-BB index was below 1 in stable and regressive condition, while it was above 1 in eight out of 19 patients with progressive disease. The PAP/CK-BB index may be of prognostic importance. CK-BB by RIA was abnormal in more cases than PAP. In this way CK-BB reflects the presence of the tumor and may be used for diagnosis; however, it does not reflect the clinical response as PAP does.     

Bone mineral density and laboratory evaluation of a type II autosomal dominant osteopetrosis carrier

Type II autosomal dominant osteopetrosis (ADO2) is an inherited disorder characterized by increased skeletal mass and characteristic abnormalities evident on radiography. Although previous investigators have described nonpenetrant individuals (carriers), it is not known whether carriers manifest subtle abnormalities. We hypothesized that ADO2 carriers would have an abnormality of osteoclast function that would lead to changes in bone mineral density (BMD), in serum tartrate-resistant acid phosphatase (TRAP), or in creatine kinase isoenzyme BB (CK-BB) levels that would permit carrier recognition. We identified a female carrier in a well-established ADO2 family and measured BMD, serum TRAP, and CK-BB concentrations. She had normal BMD, serum TRAP, and CK-BB concentrations. Thus, these measurements cannot be used to exclude carrier status in individuals who are seen for genetic counseling. However, measurements in other asymptotic carriers are necessary before concluding that these measurements are normal in all or most nonpenetrant individuals. Am. J. Med.

Derivation of a bioclinical prognostic index in severe head injury

We investigated the problem of outcome prediction from seven risk factors in 40 severely head injured patients-13 favorable and 27 unfavorable outcomes. By applying stepwise logistic discriminant analysis to the patients' data, we selected three significant risk variables: cerebrospinal fluid (CSF) CK-BB isoenzyme activity recorded on admission, severely raised intracranial pressure (more than 40 mmHg) and age, respectively. CSF CK-BB activity, which quantifies the initial neurological damage, proved to be the best prognostic factor. The presence of severe intracranial hypertension was always associated with a bad outcome, whereas its absence was not necessarily indicative of good prognosis. Finally, we combined the three selected variables into a single risk index, which allowed correct predictions in 92% of patients with favorable outcome and in 85% of patients with unfavorable outcome (total predictive efficiency 88%).
