Clinical analysis of patients with connective tissue diseases and autonomic neuropathy / 中华风湿病学杂志

ABSTRACT

Objective To summarize the clinical characteristics of patients with connective tissue diseases (CTD) and autonomic neuropathy. Methods The medical records of inpatients with CTD and autonomic neuropathy from 2005 to 2015 were retrospectively analyzed including clinical manifestations, laboratory examinations, treatment and outcome. Categorical data were expressed in percentages. Kolmogorov-Smirnov test was used to examine normal distribution. Continuous data of normal distribution were expressed as x ±s deviation, while data without a normal distribution were described as median and interquartile range (P25, P75). Results Among the nine patients included in this study, all were female, and the median age was 42 years (32~50 years old). Four patients (4/9) were systemic lupus erythematosus (SLE), three patients (3/9) were primary Sj?gren's syndrome (pSS), two patients (2/9) were rheumatic arthritis (RA), and four patients were secondary Sj?gren's syndrome (SS) (two with SLE and two with RA). Five patients (5/9) had autonomic nervous dysfunction before they were diagnosed of CTD, while four patients (4/9) developed autonomic nervous dysfunction after diagnosis of CTD. The most common symptom of autonomic nervous dysfunction was postural hypotension (9 patients, 9/9), followed by hypohidrosis (4 patients, 4/9), urinary retention (2 patients, 2/9), gastrointestinal dysmotility (2 patients, 2/9) and tonic pupil (1 patient, 11%). After treatment of CTD, autonomic symptoms of three patients improved, while the others didn't. Four of the remaining 6 patients improved after receiving other assistant treatments including vasoconstrictor, pyri-dostigmine bromide, and plasma exchange. Conclusion Patients with CTD could present with autonomic neuropathy, which is mainly characterized with postural hypotension. If patients had related symptoms, clinicians should pay more attention to whether CTD exists. If treatment for CTD couldn't improve patients' condition, other assistant treatment might be considered.
