A Case Report of Listeria Meningitis with Severe Rhabdomyolysis and Normal Renal Function.

BACKGROUND Listeria monocytogenes is known to cause meningitis, bacteremia, and rhabdomyolysis, typically associated with acute kidney injury. We present the case of a young woman who developed severe rhabdomyolysis without kidney failure in the setting of listeriosis. CASE REPORT A 22-year-old woman with a past medical history of type 1 diabetes mellitus presented with fever, headache, and vomiting. Initial blood work revealed a white blood cell count of 22 K/µL, creatine phosphokinase (CPK) level of 275 U/L, blood urea nitrogen of 9 mg/dL, and creatinine of 0.89 mg/dL. A lumbar puncture (LP) was performed and was positive for Listeria monocytogenes. Her initial point-of-care ultrasound demonstrated hyperdynamic left ventricular (LV) function. Although she was immediately started on empiric coverage for bacterial and viral meningitis with intravenous vancomycin, ceftriaxone, and acyclovir, the antimicrobial regimen was changed to ampicillin and gentamicin after the LP results were obtained. On the second hospital day, a repeat echocardiogram demonstrated a dilated LV with severely reduced function with an ejection fraction (EF) of 30%. Her CPK increased and peaked at 299 637 U/L by day 6. Despite the low EF and elevated CPK, her kidney function remained at baseline at all times. Her EF improved to 60% by hospital day 20. She received large volumes of intravenous fluids, completed a 3-week course of ampicillin, continued to improve, and was discharged to a rehabilitation facility with no deficits. CONCLUSIONS Listeria infection can be associated with severe rhabdomyolysis, which is usually associated with kidney dysfunction. Administration of large volumes of intravenous fluids may decrease this likelihood.

Persistent Severe Cerebral Edema with Neutrophil Infiltration Following Listeria Meningitis.

A 51-year-old man was admitted to the hospital with a diagnosis of Listeria monocytogenes meningitis. Diffuse cerebral edema appeared after improvement of meningitis with appropriate treatment and worsened for two months. Due to brain herniation, brain tissue leaked through the incision made during the drain insertion in a hydrocephalus surgery. We found pathological evidence of significant neutrophil infiltration with a few lymphocytes without bacterial detection in the degraded brain tissue. The present case indicates that fatal cerebral edema with significant neutrophil infiltration may develop even after appropriate treatment for L. monocytogenes meningitis.

[Post colonoscopic Listeria monocytogenes meningitis in a patient with multiple myeloma during daratumumab-based therapy].

A 69-year-old man with an unremarkable medical history presented with asymptomatic pancytopenia and diagnosed with Bence Jones protein-λ multiple myeloma (MM). Despite treatment with various chemotherapeutic regimens, myelosuppressive neutropenia occurred after each successive course; therefore, the treatment was determined to be ineffective and was discontinued. Consequently, one year after the diagnosis, a daratumumab-based therapy was initiated, and the MM was stabilized without clinical or laboratory evidences of myelosuppression. However, 18 months after the daratumumab induction, the patient developed hematochezia. Following an unremarkable lower gastrointestinal endoscopy, he presented fever and disturbed consciousness. Serum laboratory results showed liver dysfunction, and Listeria monocytogenes meningitis was diagnosed by cerebrospinal fluid examination. Empiric antibacterial treatment was administered for 3 weeks, which resolved the symptoms with no permanent neurological deficit.Daratumumab, a CD38 monoclonal antibodies, binds to expressed CD38 on myeloma cells and has an anti-myeloma cytotoxic effect but also binds to CD38 on activated macrophages. Additionally, activated macrophages play an important role in the immune defense of Listeria monocytogenes. Furthermore, inactivation of macrophages may increase the susceptibility to Listeria infection. Therefore, the possibility of infections such as Listeria meningitis should be considered in patients with MM receiving daratumumab-based therapy.

Listeria meningitis complicated by hydrocephalus in an immunocompetent child: case report and review of the literature.

BACKGROUND: Listeria monocytogenes is a Gram-positive bacteria transmitted to human by animal stools, contaminated water and food. In children, Listeria monocytogenes typically affects newborns and immunocompromised patients often leading to invasive syndromes including sepsis, brain abscesses, meningitis, meningoencephalitis and rhombencephalitis. In healthy and immunocompetent children, Listeria meningitis is rare, but can progress rapidly and may be associated with severe complications (hydrocephalus, ventriculitis, cranial nerves palsy and cerebrospinal abscesses) and high mortality rate. CASE PRESENTATION: We describe a very uncommon case of meningoencephalitis due to Listeria monocytogenes in a 11-month-old immunocompetent girl. Cerebrospinal fluid (CSF) culture was positive on the second day. Antibiotic therapy was promptly started but the disease was complicated by neurological deterioration and decompensated hydrocephalus. The child required a very demanding pediatric and neurosurgical management and was discharged after 40 days without major sequelae. CONCLUSION: Listeria is difficult to isolate and it is not susceptible to first-line treatment for bacterial meningitis with extended-spectrum cephalosporins. Early recognition is therefore crucial for a positive outcome. Pediatricians have to perform close clinical monitoring of these children and be aware of possible complications. A review of all cases of Listeria meningitis complicated by hydrocephalus in healthy children has been performed, to provide an overview on clinical features, treatment options and outcome.

Listeria monocytogenes infections: Analysis of 41 patients / Infección por Listeria monocytogenes: análisis de 41 pacientes

OBJECTIVE: We describe and analyze Listeria-related demographics and clinical features to determine the predisposing conditions for severe infections. METHODS: We performed a retrospective study using positive isolation of Listeria monocytogenes from blood, cerebrospinal fluid, and other organic fluids. Electronic health records were used to determine the epidemiological and clinical features of infections caused by L. monocytogenes. Mortality and sepsis were considered dependent variables in the statistical analyses. RESULTS: We included 41 patients in an observation period of 15 years (2003-2018), with an annual incidence rate of 1.3 cases per 100,000 population. Three main population profiles were identified: newborns, pregnant women, and other adults (17.1%, 12.2%, and 82.9%, respectively). Neuroinvasive infection was present in 17 patients (41.5%). In both univariate and multivariate analyses, neurological infections, whether meningoencephalitis, rhombencephalitis, or brain abscesses, were the main risk factors for severe forms of Listeria-related infections (odds ratio 1.8, 95% CI 1.52-2.14, p = 0.01). Malignancies, whether solid tumors or hematological neoplasms, immunosuppression, and chronic diseases were not related to either mortality or severe clinical syndromes. CONCLUSION: Infections caused by L. monocytogenes were uncommon but could cause severe sepsis and mortality, especially in susceptible populations. Our study focused on neurological involvement and severe invasive forms of listeriosis. Neuroinvasive forms were the most important risk factors for severe illness but not for mortality

INTRODUCCIÓN: Describir y analizar las características demográficas y clínicas de las infecciones por Listeria para determinar los factores predisponentes para infecciones severas. MÉTODOS: Diseñamos un estudio retrospectivo utilizando los aislamientos positivos de Listeria monocytogenes en sangre, líquido cefalorraquídeo u otros fluidos orgánicos. Se obtuvieron los registros electrónicos para conseguir las características clínicas y epidemiológicas de las infecciones causadas por L. monocytogenes. Mortalidad y sepsis fueron las variables dependientes en los análisis estadísticos. RESULTADOS: Se incluyeron 41 pacientes en un período de 15 años (2003-2018), con una incidencia anual de 1,3 casos por cada 100.000 habitantes. Identificamos tres perfiles de población: neonatos, mujeres embarazadas y resto de adultos (el 17,1%, el 12,2% y el 82,9%, respectivamente). Las formas neuroinvasivas se identificaron en 17 pacientes (41,5%). Tanto en los análisis univariados como en los multivariados, las infecciones neurológicas, bien meningoencefalitis, rombencefalitis o abscesos cerebrales, fueron los principales factores de riesgo para considerar formas severas de infección por Listeria (odds ratio 1,8; IC 1,52-2,14, p = 0,01). Las neoplasias sólidas o hematológicas, la inmunosupresión o las enfermedades crónicas no estuvieron relacionadas ni con la mortalidad ni con la presencia de severidad en la infección. CONCLUSIÓN: Las infecciones causadas por L. monocytogenes son infrecuentes, pero son causa de sepsis severa y mortalidad en poblaciones susceptibles. Nuestro estudio estuvo dirigido a la infección neuroinvasiva y otras formas graves. La forma neuroinvasiva fue el factor de riesgo más importante asociado a la infección severa, pero no a la mortalidad

Isolated De Novo Headache as the Presenting Symptom of Listeria Meningitis: A Report of 2 Cases.

BACKGROUND: Headache is a frequent symptom at the onset of Listeria meningitis, accompanied by others such as fever, altered mental status and meningeal signs, but never reported so far as an isolated symptom. METHODS AND RESULTS: Two immunocompetent males, with no history of primary headaches, went to the emergency department because of headache. The first after a sudden severe, holocranial headache without other associated symptoms, and the second after a subacute, moderate oppressive headache in temples, which 8 days later added a mild left hemiparesis. None of them had fever or meningeal signs. The initial cranial CT was unremarkable in both cases. Lumbar puncture was diagnostic for Listeria meningitis serotype IVb. CONCLUSIONS: Listeria meningitis may present as an isolated headache, with different clinical patterns, which should be taken into account when evaluating de novo unclassified headaches according to the ICHD-3 criteria.

High incidence of severe neurological manifestations and high mortality rate for adult Listeria monocytogenes meningitis in Taiwan.

The clinical characteristics and therapeutic outcomes of adult Listeria monocytogenes meningitis are not commonly examined in isolation in the literature. During a study period of 19 years (2000-2018), 366 patients with culture-proven adult bacterial meningitis (ABM) were identified in the author's hospital (264 patients in 2000-2010 and 102 patients in 2011-2018). Of the 366 ABM patients, 330 had monomicrobial infections while the other 36 had mixed infections. L. monocytogenes infection was identified in 11 of the 330 patients with monomicrobial ABM (3 in 2000-2010 and 8 in 2011-2018). These 11 patients included 5 males and 6 females, aged 47 to 76 years (median age = 61.7). None of the 11 patients had a postneurosurgical state as the underlying cause, but 3 of them contracted the infection nosocomially. Common underlying conditions included liver cirrhosis (4), systemic malignancy (3), diabetes mellitus (3), and renal disease (2). The most common clinical manifestations were fever (11), altered consciousness (8), seizure (8), bacteremia (7) and hydrocephalus (5). The therapeutic result revealed a mortality rate of 72.7% (8/11), but no significant prognostic factors were identified. The clinical features of 8 additional Taiwanese L. monocytogenes ABM patients reported in the literature, were also included for analysis. The present study revealed an increase in L. monocytogenes ABM in recent years and most patients presented with severe neurological manifestations. The current study is a preliminary overview of L. monocytogenes meningitis in adults and a further large-scale study is needed for improved delineation of this specific infectious syndrome.

Listeria Meningitis in an Immunocompetent Child: Case Report and Literature Review

We present a case of a 23 month-old boy presenting with fever, irritability and diarrhea who subsequently developed symptoms of photophobia and lethargy. Cerebrospinal fluid culture grew Listeria monocytogenes. Immunology investigations were normal. This patient had a complete and uncomplicated recovery. Listeria meningitis is a rare presentation in immunocompetent children, but should be considered in the setting of diarrhea, failure to respond to cephalosporin therapy, or suspected immunodeficiency.

Acquired immunodeficiency associated with thymoma: a case report.

BACKGROUND: Acquired immunodeficiency associated with thymoma is a rare disorder. Here we reported a case of acquired immunodeficiency with thymoma, with an unusual pattern of low CD4+ count with normal gammaglobulin levels. CASE PRESENTATION: A 70-year-old man presented to the emergency room of our hospital with a high-grade fever, headache, and nausea. He had a five-year history of unresectable thymoma treatment, including several cytotoxic regimens. He had received thoracic palliative radiotherapy 2 months prior to the emergent visit. During the previous month, he had experienced multiple febrile episodes, dry cough, fatigue, weight loss, and watery diarrhea. Upon admission, he had a high-grade fever, nausea, and immobility. Physical examination revealed indistinct consciousness, neck stiffness, and oropharyngeal candidiasis. Both cerebrospinal fluid and blood cultures yielded multiple short chains of Gram-positive rods later identified as Listeria monocytogenes, so he was diagnosed with Listeria meningitis. Intravenous administration of antibiotics was initiated, and the patient fully recovered and was discharged. Additional examination found normal immunoglobulin levels. Peripheral-blood cell counts revealed low CD4+ cell count (108 CD4+ cells/µl). His CD4+ cell count remained low after discharge. CONCLUSIONS: Our findings suggest that physicians need to be aware of severe infections due to immunodeficiency with thymoma.

Mortality from Listeria monocytogenes meningoencephalitis following escalation to alemtuzumab therapy for relapsing-remitting Multiple Sclerosis.

We report the case of a patient who died from the rare complication of Listeriosis in the immediate phase following alemtuzumab administration one month after discontinuing dimethyl fumarate (DMF). There is considerable overlap with typical post-infusion symptoms therefore high surveillance and low threshold for empirical or possible prophylactic antibiotic therapy is advocated.

The case of septical form of listeriosis with numerous abscesses of liver

The article describes the case of a septic form of a listeriosis with multiple abscesses of the liver. Given clinical example illustrates the severe course of listeriosis with the development of septicemia and lesions of internal organs. Despite the adequate etiotropic and pathogenetic treatment for listeriosis meningoencephalitis, there was a lethal outcome of the disease. The polymorphism of clinical manifestations and the range of course variants often make it difficult to diagnose listeriosis, which in turn requires a more thorough examination of patients as well as carrying out all relevant bacteriological and serological tests.

Early trigeminal nerve involvement in Listeria monocytogenes rhombencephalitis: case series and systematic review.

Listeria monocytogenes is associated with rhombencephalitis. However, the exact mechanisms of brainstem invasion remains poorly understood. Here, we demonstrate clinical and radiological data suggesting that Listeria may invade the brainstem via the trigeminal nerve. Three females (41, 64 and 70 years) with culture proven L. monocytogenes bacteremia and rhombencephalitis were investigated in the period of 2014-16. T2-weighted and contrast-enhanced T1-weighted MRI revealed a cerebellopontine abscess in all three patients, including the involvement of the trigeminal nerve root. In two patients, MRI also revealed selective contrast enhancement of the sensory trigeminal tract in the pons and medulla oblongata. Prior to any other neurological symptoms, two patients complained of hypoesthesia and a tingling sensation in the ipsilateral half of the face, consistent with sensory trigeminal nerve dysfunction on that side. In addition, we identified another 120 cases of Listeria rhombencephalitis following a systematic review. Cranial nerves VII, V, IX, and X, respectively, medulla oblongata, cerebellum and pons, were the most frequently involved brain structures. The present clinical and radiological findings corroborate earlier data from animal experiments, indicating that L. monocytogenes may be capable of retrograde intra-axonal migration along the cranial nerves. We suggest that in a subset of patients with rhombencephalitis L. monocytogenes enters the cerebellopontine angle through the trigeminal nerve, invading the brainstem via the sensory trigeminal nuclei.

Successful treatment of refractory listeria meningitis and bacteremia with trimethoprim-sulfamethoxazole in an immunocompetent child.

Listeria monocytogenes is an important cause of life-threatening bacteremia and meningoencephalitis in neonates, pregnant women, the elderly, and immunocompromised individuals. However, it is an uncommon cause of illness in immunocompetent children beyond the neonatal period. Ampicillin with or without an aminoglycoside remains the best treatment for listeriosis. Here, we report a rare case of Listeria meningitis and bacteremia in a 7-month-old immunocompetent girl, which was refractory to ampicillin plus gentamicin treatment and successfully treated by the addition of TMP/SMX.

Meningitis por Listeria monocytogenes en paciente inmunocompetente / Listeria monocytogenes meningitis in immunocompetent patient

Listeria monocytogenes es un patógeno de origen alimentario que suele producir gastroenteritis, procesos febriles, sepsis y meningitis. Afecta característicamente a neonatos, embarazadas, ancianos e inmunocomprometidos, con una epidemiología controvertida y poco conocida. Se presenta un caso de meningitis y síndrome de secreción inadecuada de hormona antidiurética secundario en paciente inmunocompetente (AU)

Listeria monocytogenes is a foodborne pathogen that usually cause gastroenteritis, fever, sepsis and meningitis, which characteristically affects immunocompromised, newborns, pregnant women and elderly people, with controversial and unknown epidemiology. We report a case of meningitis and secondary inadequate secretion of antidiuretic hormone syndrome in immunocompetent patient (AU)

An unusual presentation of paediatric Listeria meningitis with selective spinal grey matter involvement and acute demyelinating polyneuropathy.

BACKGROUND: Paediatric Listeria meningitis is rare, especially in immuno-competent children, but associated with significant mortality and morbidity and frequent complications. METHODS: We report an unusual case of Listeria meningitis in a previously healthy 35 month-old girl with selective spinal grey matter involvement and demyelination in neurophysiological studies. Despite adequate antibiotic treatment, the case was initially complicated by ventriculitis, hydrocephalus and tonsillar herniation through the foramen magnum, requiring external ventricular drainage and subsequent ventriculoperitoneal shunt insertion. Paucity of movements, hypotonia, areflexia and bladder dysfunction then became evident. RESULTS: Electromyogram and nerve conduction studies showed acute inflammatory demyelinating polyneuropathy and the patient received intravenous immunoglobulin followed by corticosteroids. MRI scans with contrast revealed extensive whole cord selective grey matter signal changes. She required extensive neurorehabilitation, making gradual (but incomplete) recovery. CONCLUSION: Spinal cord involvement is rare in neuro-listeriosis and there no previous paediatric reports of Listeria-related myelitis or demyelinating polyneuropathy. The mechanism behind these presentations is unclear but an auto-immune response to the infection might be considered.

A Delayed Cerebral Vasospasm with Infarction Is Secondary to Listeria monocytogenes Meningitis: MRI and MRA Are Diagnostically Useful.

Among patients with bacterial meningitis, a cerebral vasospasm typically occurs during the acute phase. We experienced a case of delayed cerebral vasospasm with infarction that was secondary to Listeria monocytogenes meningitis. An 82-year-old woman with Listeria monocytogenes meningitis, whose symptoms had been improving after the initiation of antibacterial therapy, fell into a coma on day 15 and developed generalized seizure. Magnetic resonance imaging (MRI) and MR angiography (MRA) indicated a cerebral vasospasm with multiple infarctions. The risk of vascular complications following acute bacterial meningitis requires close follow-up to identify neurological changes and a low threshold for vascular evaluation. In such cases, MRI and MRA have diagnostic utility.
