The detection of CPK1 (BB) in serum. A summary of sixteen cases
Insights
Creatine phosphokinase type 1 (BB isoenzyme) was detected in patient sera, often indicating brain damage, particularly after cardiopulmonary resuscitation. The brain is the likely source in most cases, though other conditions can also elevate CPK1 levels.
Area of Science:
- Biochemistry
- Neurology
- Clinical Diagnostics
Background:
- Creatine phosphokinase type 1 (BB isoenzyme), or CPK1 (BB), is an enzyme predominantly found in the brain.
- Elevated serum levels of CPK1 (BB) can suggest tissue damage, but the source requires investigation.
Purpose of the Study:
- To investigate the source of elevated serum CPK1 (BB) in patients over an 18-month period.
- To determine the correlation between CPK1 (BB) detection and specific clinical conditions, particularly neurological events.
Main Methods:
- Serum samples from 16 patients with detected CPK1 (BB) were analyzed.
- Clinical histories, including procedures like cardiopulmonary resuscitation, and evidence of cerebral damage (clinical or EEG) were reviewed.
- Other potential sources of CPK1 (BB), such as intestinal conditions, were considered.
Main Results:
- CPK1 (BB) was detected in 16 patients over 18 months.
- Eight patients had undergone cardiopulmonary resuscitation; four showed clinical or EEG evidence of cerebral damage, implicating the brain as the CPK1 source.
- Two patients with confirmed brain damage (cerebral infarct, cerebral hematoma) also had elevated CPK1 (BB). One patient with membranous enterocolitis suggested an intestinal source, while the source in five other cases was likely the brain.
Conclusions:
- Serum CPK1 (BB) detection is a potential indicator of brain damage, especially in patients who have experienced cardiac arrest or ventricular fibrillation.
- While the brain is the most probable source of CPK1 (BB) in many clinical scenarios, other conditions like enterocolitis should also be considered.
Abstract:
CPK1 (BB) was detected in the sera of 16 patients during an 18-month period. Eight of 16 had undergone cardiopulmonary resuscitation for cardiac arrest or ventricular fibrillation. Four of these eight had clinical or EEG evidence of cerebral damage. The brain is the most probable source for CPK1 in these eight cases. Two others had proven brain damage, one a massive cerebral infarct and one a traumatic cerebral hematoma requiring craniotomy. One patient had membranous enterocolitis, suggesting an intestinal source for CPK1. The source for the CPK1 in the other five cases was much less obvious, but was probably the brain.
