Sensorineural hearing loss is a well-known complication of Streptococcus pneumoniae meningitis. Given the propensity for fibrosis and ossification of the cochlea in bacterial meningitis, implantation must be performed in a timely fashion because a delayed attempt at implantation can frustrate obtaining an optimal technical result or lead to an inability to implant. Obtaining optimal audiometric outcomes is reliant on early hearing screening in patients with streptococcal meningitis. In the absence of standardized protocols, audiometric testing is often overlooked or delayed in the workup and management of meningitis. Our institution implemented a meningitis protocol with a particular focus on timing of audiometric testing in patients with meningitis. We present a patient diagnosed with streptococcal meningitis in the first week of life. Early hearing screening allowed the diagnosis of profound unilateral sensorineural hearing loss and subsequent cochlear implantation at 10 weeks of age, the youngest described in the medical literature. Despite early implantation, there was cochlear fibrosis at the time of implantation. Fortunately, the majority of electrodes were implanted to achieve a serviceable hearing outcome. Serial magnetic resonance imaging scans were obtained because of her contralateral ventriculoperitoneal shunt that allowed unique visualization of the progression of cochlear fibrosis over time. This case demonstrates the importance of including audiometric testing in a standardized meningitis protocol to diagnose hearing loss in a timely and accurate way and to achieve optimal long-term hearing outcomes.

A case of neonatal sepsis caused by Edwardsiella tarda, an uncommon pathogen typically associated with aquatic lifeforms, is described. The infant presented in septic shock with seizures and respiratory failure and was found to have meningitis, ventriculitis and a brain abscess requiring drainage. Only a small number of case reports of neonatal E. tarda infection, several with sepsis with poor auditory or neurodevelopmental outcomes or meningitis, have been described in the literature. This case report suggests that E. tarda, while uncommon, can be a cause of serious central nervous system disease in the neonatal population and that an aggressive approach to pursuing and treating complications may lead to improved neurodevelopmental outcomes.

Importance: Subarachnoid hemorrhage is typically diagnosed by noncontrast head computed tomography (CT); lumbar puncture is recommended if computed tomography is nondiagnostic, although CT cerebral angiography has been promoted as an alternative to lumbar puncture in this diagnostic pathway. The outcomes of this debate in practice have not been studied. Objective: To determine whether CT cerebral angiography use has increased in lieu of lumbar puncture among emergency department (ED) patients with headache, with an increase in unruptured intracranial aneurysm detection. Design, Setting, and Participants: This retrospective cohort study took place in 21 community EDs of an integrated health care system in Northern California between 2015 and 2021. Participants were adult (aged >17 years) health plan members with a chief concern of headache. Exclusions were prior diagnoses of subarachnoid hemorrhage, unruptured intracranial aneurysm, cerebral arteriovenous malformation, or cerebrospinal fluid shunt. Data were analyzed from October to November 2023. Exposures: CT cerebral angiography and/or lumbar puncture during the ED encounter. Main Outcomes and Measures: Primary and secondary outcomes were 14-day and 90-day unruptured intracranial aneurysm detection, respectively. Safety outcomes were missed diagnoses of subarachnoid hemorrhage or bacterial meningitis. The annual incidence of unruptured intracranial aneurysm detection was normalized to the incidence of subarachnoid hemorrhage (UIA:SAH ratio). Average annualized percentage changes were quantified using joinpoint regression analysis. Results: Among 198â¯109 included ED encounters, the mean (SD) age was 47.5 (18.4) years; 140â¯001 patients (70.7%) were female; 29â¯035 (14.7%) were Black or African American, 59â¯896 (30.2%) were Hispanic or Latino, and 75â¯602 (38.2%) were White. Per year, CT cerebral angiography use increased (18.8%; 95% CI, 17.7% to 20.3%) and lumbar punctures decreased (-11.1%; 95% CI, -12.0% to -10.4%), with a corresponding increase in the 14-day UIA:SAH ratio (3.5%; 95% CI, 0.9% to 7.4%). Overall, computed tomography cerebral angiography use increased 6-fold relative to lumbar puncture, with a 33% increase in the detection of UIA. Results were similar at 90 days and robust to sensitivity analyses. Subarachnoid hemorrhage (1004 cases) and bacterial meningitis (118 cases) were misdiagnosed in 5% and 18% of cases, respectively, with no annual trends (P = .34; z1003 = .95 and P = .74; z117 = -.34, respectively). Conclusions and Relevance: In this cohort study of ED patients with headache, increases in CT cerebral angiography use were associated with fewer lumbar punctures and higher detection of unruptured intracranial aneurysms, with no significant change in missed diagnoses of subarachnoid hemorrhage or bacterial meningitis. While this shift in diagnostic strategy appeared safe in the short-term, the long-term consequences remain unclear.

Streptococcus suis is one of the most common zoonotic pathogens, in humans and can cause meningitis, endocarditis, arthritis and sepsis. Human cases of Streptococcus suis infection have been reported worldwide, and most of those cases occurred in Asia. Hearing loss is the most common sequela of Streptococcus suis meningitis. Streptococcus suis infection complicated with acute cerebral infarction has rarely been reported. Therefore, to provide a reference for this disease, we reported a case of acute multiple brain infarctions associated with Streptococcus suis infection. In our report, a 69yearold male patient had Streptococcus suis meningitis and sepsis, which were associated with multiple acute cerebral infarctions in the pons and bilateral frontotemporal parietal occipital lobes. After treatment, the patient exhibited cognitive impairment, dyspraxia and irritability. There are limited case reports of cerebral infarction associated with Streptococcus suis infection, and further research is needed to determine the best treatment method.

BACKGROUND: Hearing loss is a common sequala of Streptococcus suis (S. suis) meningitis, but few have addressed cochlear implantation (CI) candidates with S. suis meningitis. OBJECTIVES: To assess the clinical characteristics and CI postoperative outcomes in S. suis meningitis patients. MATERIAL AND METHODS: Eight S. suis meningitis patients underwent CI at Sun Yat-sen Memorial Hospital between 2020 and 2023. Control groups included (1) non-Suis meningitis patients (n = 12) and (2) non-meningitis patients (n = 35). Electrode impedances and neural response telemetry (NRT) thresholds were recorded at one month after surgery. The auditory performance-II (CAP) and speech intelligibility rating (SIR) were recorded at the last visit. RESULTS: CAP scores of S. suis meningitis patients were significantly lower than those of non-Suis meningitis and non-meningitis patients (p = .019; p<.001). And NRT thresholds of S. suis meningitis patients were higher than those of non-Suis meningitis and non-meningitis patients (p = .006; p = .027). CONCLUSIONS AND SIGNIFICANCE: It is recommended for S. suis meningitis CI candidates to undergo CI promptly after controlling infection, preferably within four to six weeks. CI users with S. suis meningitis tend to exhibit suboptimal hearing rehabilitation outcomes, possibly associated with the more severe damage on spiral ganglion cells after S. suis meningitis.

Bacterial meningitis is a life-threatening disease. Bacterial meningitis patients are prone to develop acute hyponatremia. In the central nervous system infection hyponatremia could be due to the Syndrome of Inappropriate Anti Diuretic Hormone secretion. The frequency of hyponatremia in adults with acute bacterial meningitis patients was seen in this study. This cross-sectional study was conducted in the Internal Medicine Department of Mymensingh Medical College Hospital, Mymensingh, Bangladesh from February 2016 to July 2016. A total of 50 patients were enrolled in this study by purposive sampling. Among 50 acute bacterial meningitis patients, 33 (66%) were diagnosed as hyponatremic state. The mean serum sodium level of 33 hyponatremic bacterial meningitis cases was 130.66±2.95 mmol/L. Most of the cases (78.79%) were mild hyponatremic state (130 mmol/L-135 mmol/L) whereas 18.18% were revealed as moderate hyponatremia (125 mmol/L-129 mmol/L). Only 3.03% of cases were presented as severe cases (≤124 mmol/L). The result revealed that a large number of patients with acute bacterial meningitis were suffering from hyponatremia and in the majority of cases were mildly hyponatremic.

OBJECTIVE: The primary objective was to elucidate the epidemiologic characteristics, risk determinants, and clinical outcomes associated with Pseudomonas aeruginosa-induced meningitis. METHODS: All cases of meningitis caused by Pseudomonas aeruginosa that were treated at the hospital between 2012 and 2022 were retrospectively analyzed and detailed. RESULTS: During a 10-year period, only 10 patients satisfied the inclusion criteria. Three patients had previously undergone neurosurgical procedures and 4 patients had leukemia. CONCLUSIONS: Although Pseudomonas aeruginosa meningitis possesses a low incidence rate, the rate of mortality is high. Patients with leukemia or those who have undergone neurosurgery are the most susceptible to diagnosis. Cases of severe neutropenia present only mild or no cerebrospinal fluid pleocytosis. In patients with sensitive Pseudomonas aeruginosa meningitis, the timely use of anti-Pseudomonas carbapenems for intravenous treatment is highly effective. For drug-resistant Pseudomonas aeruginosa meningitis, intrathecal polymyxins administration can be an effective treatment option.

PURPOSE: Pneumococcal meningitis is a major cause of hearing loss and permanent neurological impairment despite widely available antimicrobial therapies to control infection. Methods to improve hearing outcomes for those who survive bacterial meningitis remains elusive. We used a mouse model of pneumococcal meningitis to evaluate the impact of mononuclear phagocytes on hearing outcomes and cochlear ossification by altering the expression of CX3CR1 and CCR2 in these infected mice. METHODS: We induced pneumococcal meningitis in approximately 500 C57Bl6 adult mice using live Streptococcus pneumoniae (serotype 3, 1 × 105 colony forming units (cfu) in 10 µl) injected directly into the cisterna magna of anesthetized mice and treated these mice with ceftriaxone daily until recovered. We evaluated hearing thresholds over time, characterized the cochlear inflammatory response, and quantified the amount of new bone formation during meningitis recovery. We used microcomputed tomography (microCT) scans to quantify cochlear volume loss caused by neo-ossification. We also performed perilymph sampling in live mice to assess the integrity of the blood-perilymph barrier during various time intervals after meningitis. We then evaluated the effect of CX3CR1 or CCR2 deletion in meningitis symptoms, hearing loss, macrophage/monocyte recruitment, neo-ossification, and blood labyrinth barrier function. RESULTS: Sixty percent of mice with pneumococcal meningitis developed hearing loss. Cochlear fibrosis could be detected within 4 days of infection, and neo-ossification by 14 days. Loss of spiral ganglion neurons was common, and inner ear anatomy was distorted by scarring caused by new soft tissue and bone deposited within the scalae. The blood-perilymph barrier was disrupted at 3 days post infection (DPI) and was restored by seven DPI. Both CCR2 and CX3CR1 monocytes and macrophages were present in the cochlea in large numbers after infection. Neither chemokine receptor was necessary for the induction of hearing loss, cochlear fibrosis, ossification, or disruption of the blood-perilymph barrier. CCR2 knockout (KO) mice suffered the most severe hearing loss. CX3CR1 KO mice demonstrated an intermediate phenotype with greater susceptibility to hearing loss compared to control mice. Elimination of CX3CR1 mononuclear phagocytes during the first 2 weeks after meningitis in CX3CR1-DTR transgenic mice did not protect mice from any of the systemic or hearing sequelae of pneumococcal meningitis. CONCLUSIONS: Pneumococcal meningitis can have devastating effects on cochlear structure and function, although not all mice experienced hearing loss or cochlear damage. Meningitis can result in rapid progression of hearing loss with fibrosis starting at four DPI and ossification within 2 weeks of infection detectable by light microscopy. The inflammatory response to bacterial meningitis is robust and can affect all three scalae. Our results suggest that CCR2 may assist in controlling infection and maintaining cochlear patency, as CCR2 knockout mice experienced more severe disease, more rapid hearing loss, and more advanced cochlear ossification after pneumococcal meningitis. CX3CR1 also may play an important role in the maintenance of cochlear patency.

We report the case of a 69-year-old man with bacterial meningitis who presented with ataxie optique in the peripheral part of the left visual field in both hands. A detailed neurological examination with contrast-enhanced brain MRI in the early stage of the clinical course identified a small subdural abscess and pialitis in the right parietal area. A favorable outcome was obtained with antibiotic therapy alone. In a case with higher brain dysfunction of unknown cause in the clinical course of bacterial meningitis, a detailed neurological examination may be helpful to identify the causative site.

AIM: A low Glasgow Coma Scale Score (GCS) on admission is a known predictor of poor outcome from childhood bacterial meningitis. In turn, the factors associated with the admission GCS are less known. Our aim was to identify them, both for clinical alerts of reserved prognosis and to find potential targets for intervention. METHODS: This study is a secondary analysis of data collected prospectively in Angola and in Latin America between 1996 and 2007. Children with bacterial meningitis were examined on hospital admission and their GCS was assessed using the age-adjusted scale. Associations between on-admission GCS and host clinical factors were examined. RESULTS: A total of 1376 patients with confirmed bacterial meningitis were included in the analysis (609 from Latin America and 767 from Angola). The median GCS was 13 for all patients (12 in Angola and 13 in Latin America). In the multivariate analysis, in the areas combined, seizures, focal neurological signs, and pneumococcal aetiology associated with GCS <13, as did treatment delay in Latin America. CONCLUSION: Besides pneumococcal aetiology, we identified characteristics, easily registrable on admission, which are associated with a low GCS in childhood bacterial meningitis. Of these, expanding pneumococcal vaccinations and treatment delays could be modified.

OBJECTIVES: Bacterial meningitis is a leading cause of acquired sensorineural hearing loss (SNHL). Treatment and prevention of bacterial meningitis have improved over time, but rates of neurologic complications have not been recently studied. The objective here is to present an updated population-based review of hearing loss as a sequela of bacterial meningitis. METHODS: A retrospective cohort study was conducted between 2010 and 2022 of children discharged with bacterial meningitis, using the Pediatric Health Information System's (PHIS) database. Rates of hearing loss and mortality were evaluated over time. RESULTS: A total of 6138 children with a primary diagnosis of bacterial meningitis were identified (3520 male [57.3%], mean age 5.8 months [2.0, 61.2]). Of these, 277 (4.51%) were diagnosed with hearing loss. Children with hearing loss were significantly older (23.6 vs. 5.3 months, p < 0.01), but differences in gender, race, or ethnicity had no association with hearing loss. Streptococcus pneumoniae, Hemophilus influenzae, and Neisseria meningiditis were associated with significantly higher rates of hearing loss than other etiologies (p < 0.01). Children with hearing loss had a higher rate of receiving dexamethasone than children without hearing loss. Overall mortality rate was 2.1%. Hearing loss and mortality demonstrated significant decreases over the study period. CONCLUSION: Hearing loss remains a common sequela of bacterial meningitis despite widespread uptake of vaccines for preventing S. pneumoniae, H. influenzae, and N. meningitidis. Dexamethasone was not associated with decreased rates of hearing loss in this cohort. From 2010 to 2022, there was a significant decrease in overall rates of mortality and hearing loss for children with bacterial meningitis. LEVEL OF EVIDENCE: 3: retrospective case-control series Laryngoscope, 134:3820-3825, 2024.

INTRODUCTION: Although concomitant pneumonia is sometimes diagnosed in childhood bacterial meningitis, its role in the illness course and prognosis is not known. We examined these associations using prospectively collected data from Finland, Latin America and Angola. METHODS: This was a secondary descriptive analysis of prospectively collected data (clinical and laboratory findings at admission, during hospitalisation and outcome) from five clinical bacterial meningitis trials. We included children aged 2 months to 15 years from sites with confirmed bacterial meningitis and potential concomitant pneumonia (diagnosed clinically with or without a chest radiograph). RESULTS: Pneumonia was not observed in the 341 children included in Finland. Pneumonia was observed in 8% (51/606) of children in Latin America and in 46% (377/819) in Angola (p < 0.0001). In multivariate analyses, predisposing factors for pneumonia in Latin America were age <1 year, seizures and severe anaemia; the corresponding factors for Angola were preadmission duration of illness >3 days and non-meningococcal meningitis. Concomitant pneumonia increased the severity of the disease and disabling sequelae. CONCLUSION: Bacterial meningitis with pneumonia is a major, previously undescribed entity of severe bacterial meningitis, especially in Angola.

Here, we report the case of a woman in her 40s who came with pyogenic meningitis and infarcts in the brain. While on treatment with antibiotics, she developed new-onset weakness involving bilateral lower limbs and one upper limb 2 weeks into the course of illness. MRI of the spine showed an infarct in the spinal cord. Spinal cord infarction as a complication of pyogenic meningitis is not well recognised unlike tuberculosis meningitis. Unlike ischaemic strokes where thrombolysis is done, for stroke related to infections, there are no definite strategies. Our patient was treated with physiotherapy, continued on antibiotics and slowly recovered over months and at 18-month follow-up, she was walking with a walker. The exact mechanism of thrombosis is not known but may be due to inflammation of the arterial wall and activation of the procoagulant cascade by infection-triggered inflammation. Spinal cord infarction can occur at any phase of the infection and may occur despite appropriate response to antibiotic treatments.

A man in his 30s, with sinonasal undifferentiated carcinoma status post resection 6 years prior, presented with acute onset of fever, headache and altered mentation. The patient was diagnosed with bacteremia and meningitis due to Streptococcus pneumoniae A standard antibiotic and corticosteroid regimen was started. Brain MRI showed an encephalocele abutting the superolateral nasopharynx mucosa. After several days of clinical improvement, the patient's mental status and headache acutely relapsed. A CT head venogram showed a large volume pneumocephalus originating from the region of a surgical defect. Management included external ventricular drain placement followed by right pterional craniotomy with skull base packing. Skull base defects increase the risk of life-threatening conditions such as bacterial meningitis and pneumocephalus. It is crucial for clinicians to be aware of the possibility of cranial surgical defects developing years after surgery.

Importance: Few studies have examined the incidence of long-term disabilities due to bacterial meningitis in childhood with extended follow-up time and a nationwide cohort. Objective: To describe the long-term risks of disabilities following a childhood diagnosis of bacterial meningitis in Sweden. Design, Setting, and Participants: This nationwide retrospective registry-based cohort study included individuals diagnosed with bacterial meningitis (younger than 18 years) and general population controls matched (1:9) by age, sex, and place of residence. Data were retrieved from the Swedish National Patient Register from January 1, 1987, to December 31, 2021. Data were analyzed from July 13, 2022, to November 30, 2023. Exposure: A diagnosis of bacterial meningitis in childhood recorded in the National Patient Register between 1987 and 2021. Main Outcomes and Measures: Cumulative incidence of 7 disabilities (cognitive disabilities, seizures, hearing loss, motor function disorders, visual disturbances, behavioral and emotional disorders, and intracranial structural injuries) after bacterial meningitis in childhood. Results: The cohort included 3623 individuals diagnosed with bacterial meningitis during childhood and 32â¯607 controls from the general population (median age at diagnosis, 1.5 [IQR, 0.4-6.2] years; 44.2% female and 55.8% male, median follow-up time, 23.7 [IQR, 12.2-30.4] years). Individuals diagnosed with bacterial meningitis had higher cumulative incidence of all 7 disabilities, and 1052 (29.0%) had at least 1 disability. The highest absolute risk of disabilities was found for behavioral and emotional disorders, hearing loss, and visual disturbances. The estimated adjusted hazard ratios (HRs) showed a significant increased relative risk for cases compared with controls for all 7 disabilities, with the largest adjusted HRs for intracranial structural injuries (26.04 [95% CI, 15.50-43.74]), hearing loss (7.90 [95% CI, 6.68-9.33]), and motor function disorders (4.65 [95% CI, 3.72-5.80]). The adjusted HRs for cognitive disabilities, seizures, hearing loss, and motor function disorders were significantly higher for Streptococcus pneumoniae infection (eg, 7.89 [95% CI, 5.18-12.02] for seizure) compared with Haemophilus influenzae infection (2.46 [95% CI, 1.63-3.70]) or Neisseria meningitidis infection (1.38 [95% CI, 0.65-2.93]). The adjusted HRs for cognitive disabilities, seizures, behavioral and emotional disorders, and intracranial structural injuries were significantly higher for children diagnosed with bacterial meningitis at an age below the median. Conclusions and Relevance: The findings of this cohort study of individuals diagnosed with bacterial meningitis during childhood suggest that exposed individuals may have had an increased risk for long-term disabilities (particularly when diagnosed with pneumococcal meningitis or when diagnosed at a young age), highlighting the need to detect disabilities among surviving children.

Streptococcus salivarius is part of the normal oral cavity and gastrointestinal tract microflora and an unusual cause of acute bacterial meningitis. We herein report an 81-year-old man with S. salivarius meningitis, which led to a diagnosis of early esophageal cancer and early gastric cancer. S. salivarius infection may occur through the gastrointestinal mucosa when it is disrupted in association with early gastrointestinal cancer. To our knowledge, this is the first report describing S. salivarius meningitis associated with multiple early gastrointestinal cancers in the absence of other sources of infection.

PURPOSE: Bacterial meningitis remains a global threat due to its high mortality. It is estimated that >1.2 million cases of bacterial meningitis are reported annually. Intracranial vasculopathy is an important, under-documented complication, easily detected by transcranial Doppler (TCD) ultrasonography. Following the PRISMA Guidelines, we reviewed the utility of TCD in bacterial meningitis. METHODS: This is a systematic review of observational studies on the use of TCD in patients with CSF-proven bacterial meningitis. Characteristic changes in TCD parameters along the course of the disease, correlation of TCD findings with neuroimaging, and functional outcomes were evaluated. RESULTS: Nine studies were included with a total of 492 participants (mean age of 42). The most common TCD finding was intracranial arterial stenosis of the MCA (50%-82%) and ischemia (33%) was the predominant neuroimaging finding. The presence of an abnormal TCD finding increased the risk of poor outcomes as high as 70%. CONCLUSIONS: Patients diagnosed with bacterial meningitis who underwent TCD show alterations in cerebral blood flow, correlating with imaging findings and poor outcomes. It aids in the diagnosis of its sequelae and can predict the prognosis of its outcome. TCD is a cost-effective, reliable modality for diagnosing vasculopathy associated with bacterial meningitis. It may prove useful in our armamentarium of management. Large prospective studies with long-term follow-up data may help establish the use of TCD in bacterial meningitis.

The optimal duration of antibiotic treatment for the most common bacterial meningitis etiologies in the pediatric population, namely Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis, is not well-established in the literature. Therefore, we aimed to perform an updated meta-analysis comparing shorter versus longer antibiotic treatment in children with meningitis. PubMed, EMBASE, and Cochrane databases were searched for randomized controlled trials (RCTs) that compared shorter (up to 7 days) versus longer (10 days or double the days of the equivalent short course) duration of antibiotic treatment in children with meningitis and reported the outcomes of treatment failure, death, neurologic sequelae, non-neurologic complications, hearing impairment, nosocomial infection, and relapse. Heterogeneity was examined with I2 statistics. RevMan 5.4.1 was used for statistical analysis and RoB-2 (Cochrane) for risk of bias assessment. Of 684 search results, 6 RCTs were included, with a cohort of 1333 children ages 3 weeks to 15.5 years, of whom 49.51% underwent a short antibiotic course. All RCTs included monotherapy with ceftriaxone, except one, which added vancomycin as well. No differences were found comparing the short and long duration of therapy concerning treatment failure, relapse, mortality, and neurologic complications at discharge and at follow-up. Conclusion: Because no statistically significant differences were found between groups for the analyzed outcomes, the results of this meta-analysis support shorter therapy. However, generalizing these results to complicated meningitis and infections caused by other pathogens should be made with caution. (PROSPERO identifier: CRD42022369843). What is Known: ⢠Current recommendations on the duration of antibiotic therapy for bacterial meningitis are mostly based on clinical practice. ⢠Defining an optimal duration of antibiotic therapy is essential for antimicrobial stewardship achievement, improving patient outcomes, and minimizing adverse effects. What is New: ⢠There are no differences between shorter versus longer antibiotic treatment duration in regard to treatment failure, relapse, mortality, neurologic complications, and hearing impairment at discharge and at follow-up.
