Peripheral and autonomic nerve function in diabetic ketoacidosis
Lancet (London, England)
|July 24, 1976
Summary
Diabetic ketoacidosis can damage peripheral nerves, but function improves over three months. Autonomic nerves showed no consistent changes, suggesting peripheral nerves are more vulnerable to acute metabolic injury.
Area of Science:
- Neurology
- Endocrinology
- Metabolic disorders
Background:
- Diabetic ketoacidosis is a serious complication of diabetes mellitus.
- Nerve damage (neuropathy) is a known complication of diabetes.
- The specific impact of ketoacidosis on peripheral and autonomic nerve function requires further investigation.
Purpose of the Study:
- To assess peripheral and autonomic nerve function in diabetic patients following ketoacidosis.
- To evaluate the recovery of nerve function over a 3-month period.
- To determine the relative susceptibility of peripheral versus autonomic nerves to acute metabolic damage.
Main Methods:
- Longitudinal study design over 3 months.
- Assessment of peripheral nerve function (motor conduction velocity, terminal latency) in ulnar and common peroneal nerves.
- Evaluation of autonomic function using standardized tests.
Main Results:
- All seven diabetic patients showed significant improvement in peripheral nerve function.
- Motor conduction velocity and terminal latency of tested nerves markedly improved.
- Five patients had abnormal autonomic function tests, but no consistent changes were observed during the study period.
Conclusions:
- Peripheral nerve function demonstrates notable recovery within 3 months after diabetic ketoacidosis.
- Autonomic nerve function showed less consistent changes, indicating potential differential vulnerability.
- Peripheral nerves may be more susceptible to acute metabolic damage from ketoacidosis compared to autonomic fibers.
