Abstract
The prevalence of chronic polyneuropathy will increase due to the aging population, and therefore, it becomes ever so important to optimize the diagnostic process. However, it is uncertain which blood tests are required and when nerve conduction studies (NCS) should be done in the workup of chronic polyneuropathy. We aimed to investigate the methodology used to develop national polyneuropathy guidelines and to provide an overview and strength of evidence of the recommendations. We searched PubMed and websites of national neurological associations as listed on the website of the World Federation of Neurology to identify national guidelines pertaining to the workup of chronic polyneuropathy by neurologists in an outpatient clinic setting. We identified three national guidelines in the United States and seven national guidelines in Denmark, France, Germany, the Netherlands, Norway, Spain, and Turkey. The methodology used to develop the guidelines differed greatly. All guidelines recommend a series of blood tests. Some guidelines advise to conduct NCS in all patients, while other guidelines advise to conduct NCS when certain symptoms are present. There is variation in recommendations about the extensiveness of NCS, but all mention measuring the sural nerve and the motor peroneal nerve. The evidence for the recommendations is graded as low. Despite some overlap, there are disparities between guidelines regarding the workup that is advised to do in patients with chronic polyneuropathy. It remains unclear which combination of blood tests are to be strongly recommended. Furthermore, it is undetermined whether NCS are always necessary.
期刊介绍:
The Journal of the Peripheral Nervous System is the official journal of the Peripheral Nerve Society. Founded in 1996, it is the scientific journal of choice for clinicians, clinical scientists and basic neuroscientists interested in all aspects of biology and clinical research of peripheral nervous system disorders.
The Journal of the Peripheral Nervous System is a peer-reviewed journal that publishes high quality articles on cell and molecular biology, genomics, neuropathic pain, clinical research, trials, and unique case reports on inherited and acquired peripheral neuropathies.
Original articles are organized according to the topic in one of four specific areas: Mechanisms of Disease, Genetics, Clinical Research, and Clinical Trials.
The journal also publishes regular review papers on hot topics and Special Issues on basic, clinical, or assembled research in the field of peripheral nervous system disorders. Authors interested in contributing a review-type article or a Special Issue should contact the Editorial Office to discuss the scope of the proposed article with the Editor-in-Chief.
