Abstract:
Objective:To understand the clinical characteristics of serotonin syndrome (SS) induced by combined use of linezolid and serotonergic drugs.Methods:Relevant databases at home and abroad as of February 2021 were searched and case reports of SS induced by linezolid combined with serotonergic drugs were collected. Clinical information including patients′ basic characteristics (gender, age, underlying disease, etc.), linezolid and serotonergic drugs application (medication reasons, usage and dosage, drug elution period, etc.), and the occurrence time, clinical manifestations, intervention measures, and outcomes of SS were extracted and analyzed by descriptive statistical method.Results:A total of 50 patients derived from 46 literature were enrolled in the study, including 23 males and 27 females. Of them, 49 patients were aged from 23 to 98 years, and one patient was 4 years old. The reasons for using serotonergic drugs were mental illness (36 patients), pain (8 patients), and Parkinson′s disease (2 patients), etc.; the reasons for using linezolid were staphylococcal infection (24 patients), enterococcal infection (13 patients), and empirical anti-infection treatments (11 patients), etc. Among the 50 patients, 48 were treated with serotonergic drugs and then with linezolid, and 2 were treated with linezolid and then with serotonergic drugs; the drug washout period was not recorded in 44 patients and not long enough in the other 6 patients; the serotonergic drugs were given orally in 40 patients and by intravenous infusion in 10 patients; 35 patients had usage and dosage records, which were all in line with the requirements of drug labels; 27, 16, 5, and 2 patients were treated with 1, 2, 3, and 4 kinds of serotonergic drugs respectively, and the drugs used mainly were selective serotonin reuptake inhibitors, serotonergic drugs and norepinephrine reuptake inhibitors, tricyclic antidepressants, and opioids, etc. Except the administration route of linezolid was not mentioned in 12 patients, it was given by intravenous infusion in 27 patients and orally in 11 patients. The frequency of medication met the requirements of drug labels in 49 patients, and the medication frequency of one child was lower than that specified in the drug labels. SS occurred 3 hours to 20 days after combined use of drugs, mostly 1 to 5 days. The clinical manifestations were mental state change, autonomic nerve dysfunction, and neuromuscular dysfunction in 45, 47, and 45 patients, respectively. After discontinuation of linezolid and/or serotonergic drugs and receiving symptomatic treatments for 2 hours to 9 days, 43 patients were improved, 1 patient died of cardiac arrest after SS occurrence, and 6 patients died of the primary diseases after the symptoms of SS were controlled.Conclusions:SS due to linezolid combined with serotonergic drugs mostly occurred 1 to 5 days after combined use of above 2 drugs, and the clinical manifestations were similar to SS induced by other reasons. After discontinuation of linezolid and serotonergic drugs and symptomatic and supportive treatments, the overall prognosis is acceptable, but serious SS can lead to death.
