OBJECTIVE: To analyze the clinical characteristics and outcomes of multiple myeloma (MM) patients infected with Listeria monocytogenes (LM) in novel agent era, so as to improve clinicians' understanding. METHODS: Clinical data of 4 MM patients infected with LM in Beijing Chao-yang Hospital from October 2018 to October 2022 was analyzed retrospectively. RESULTS: The average age of the 4 patients was (57.5±4.1) years old. All the patients did not reach deep remission from induction therapy or experienced multiple recurrences of MM, with significant decreased immunoglobulin levels and lymphocyte counts. The initial clinical manifestation was all fever. Three patients developed nervous system symptoms 2-3 days after onset and cerebrospinal fluid examination indicated meningitis. The sensitive anti-infection agents were given according to pathogenic test results 4-5 days after onset. After treatment, two patients recovered, one patient gave up treatment and died after discharged from hospital, and one critical patient died despite exposure to sensitive antibiotics. CONCLUSION MM patients, with the application of novel agents, may have increased risk of LM infection, even critical cases. LM prevention and prompt therapy in early stage for suspected patients is key to reducing the risk of severe infection and mortality.

Listeria brainstem encephalitis with myelitis is extremely rare in clinical practice.Since the clinical manifestations are non-specific,MRI is helpful for diagnosis.Positive cerebrospinal fluid culture is considered the gold standard for diagnosis.This article reports a case of an immunocompetent individual with listeria brainstem encephalitis with myelitis,aiming to enhance the awareness of this condition.

OBJECTIVES: To investigate the clinical characteristics of patients with listeriosis and to provide a basis for diagnosis, treatment, prevention and control of hospital infection. METHODS: A total of 10 inpatients, who suffered from the listeriosis in Xiangya Hospital, Central South University from January 2013 to June 2019, were retrospectively collected for this study. The characteristics of the patients' age, gander, basic information, case type, clinical manifestations, first consultation department, days of diagnosis, infection indicator, specimen type, results of drug sensitivity, treatment plan, hospital infection or not, outcome, follow-up data were analyzed. RESULTS: Two cases were pregnant women and other were non-pregnant adults among 10 patients with listeriosis. Among them, there were 3 cases with hospital acquired infection. The age of patient onset was 27-71 years old, and the time from onset to diagnosis was 5-36 days. Five cases had fever, and other 5 cases had not fever. There were headache, fatigue, local pain, and other specialized symptoms in the 10 patients.The white blood cell count,the neutrophil ratio, the inflammatory index C-reactive protein, the procalcitonin were all increased, and the erythrocyte sedimentation was accelerated in the 10 patients.All the patients were sensitive to ampicillin, penicillin G, meropenem, and compound sinomine. CONCLUSIONS Listeriosis often affects the patients with low immunity, which often leads to misdiagnosis or missed diagnosis in clinic.So early prevention, early diagnosis, and early treatment can reduce mortality; it is important for departments of nosocomial infection management to manage patients' diet for avoiding outbreaks of listeriosis in hospital.
