Paraneoplastic neuromuscular syndromes at the outpatient level

Abstract

Objective: to develop tactics for the differential diagnosis of paraneoplastic neuromuscular syndromes in patients at the outpatient level.Materials and methods: the study included 50 patients with classical neuromuscular paraneoplastic syndromes (experimental group) and 50 patients with neuromuscular syndromes of non-paraneoplastic nature (control group). All patients underwent a comprehensive laboratory and instrumental examination at the Regional Consultative and Diagnostic Center of the Ministry of Health of the Rostov Region from 2014 to 2018.Results: the evaluation of clinical differences in patients of the experimental and control groups was created. When comparing the laboratory parameters, it was revealed that the SFMC, D-dimer, CRP-2 levels significantly increased in patients with paraneoplastic lesions (p <0.05). In the experimental group, a significant increase in the amplitude of the M-response from the sensory nerves (> 5.25 mV) was noted. Based on obtained data, differential diagnosis algorithms for patients with studied neuromuscular lesions at the outpatient level have been developed.Conclusions: the conducted study allows the implementation of non-serological diagnostics algorithms for classical neuromuscular paraneoplastic syndromes in outpatient practice.
