Abstract Cryptococcal infection of central nervous system commonly involves meningitis or meningoencephalitis, but rarely mimics inflammatory myelitis. We present short segment myelitis as a dominant manifestation caused by Cryptococcus neoformans in a patient with nephrotic syndrome under immunosuppressive therapy. This case report highlights Cryptococcus neoformans as a potential etiological factor for short segment myelitis in immunocompromised hosts.

Abstract Cryptococcus neoformans, Cryptococcus gattii and Candida albicans are opportunistic fungal pathogens associated with infections in immunocompromised hosts. Cryptococcal meningitis (CM) is the leading fungal cause of HIV-related deaths globally, with the majority occurring in Africa. The human immune response to C. albicans infection has been studied extensively in large genomics studies whereas cryptococcal infections, despite their severity, are comparatively understudied. Here we investigated the transcriptional response of immune cells after in vitro stimulation with in vitro C. neoformans, C. gattii and C. albicans infection of peripheral blood mononuclear cells (PBMCs) collected from healthy South African volunteers. We found a lower transcriptional response to cryptococcal stimuli compared to C. albicans and unique expression signatures from all three fungal stimuli. This work provides a starting point for further studies comparing the transcriptional signature of CM in immunocompromised patients, with the goal of identifying biomarkers of disease severity and possible novel treatment targets.

Abstract Background In mid-2018, the Australian childhood 13-valent pneumococcal conjugate vaccine schedule changed from 3+0 to 2+1, moving the third dose to 12 months of age, to address increasing breakthrough cases of invasive pneumococcal disease (IPD), predominantly in children aged >12 months. This study assessed the impact of this change using national IPD surveillance data.Methods Pre- and postschedule change 3-dose 13-valent pneumococcal conjugate vaccine breakthrough cases were compared by age group, serotype, and clinical syndrome. Annual rates of breakthrough cases were calculated (per 100 000) using respective birth cohort sizes and 3-dose vaccine coverage. Using time-series modelling, observed IPD rates in children aged 12 months was 2.8 per 100 000 (n = 557; 11 birth cohorts). Serotype 3 replaced 19A as predominant breakthrough serotype (respectively, 24% and 65% in 2013 to 60% and 20% in 2022) followed by 19F. In breakthrough cases, the most frequent clinical phenotype was bacteremic pneumonia (69%), with meningitis accounting for 3%–4%. In cohorts eligible for 2+1 versus 3+0 schedules, rate of breakthrough cases was lower for all vaccine serotypes, except type 3 (incidence rate ratio, 0.50 [95% confidence interval, .28–.84] and 1.12 [0.71–1.76], respectively). Observed compared to expected IPD was 51.7% lower (95% confidence interval, −60.9 to −40.7%) for vaccine serotypes, but the change for nonvaccine types was not significant 12% (−9.6 to 39.7).Interpretations The 2+1 schedule is likely superior to 3+0 for overall IPD control, a finding that may be worth consideration for other countries considering or using 3+0 PCV schedules.

by Musa Mohammed Ali Background Meningitis poses a significant challenge to public health in low-income nations, such as Ethiopia, with a particular impact on newborns. The magnitude and etiologies of meningitis vary based on geographic location and age of patients. There is limited data regarding the magnitude and etiology of meningitis from Sidama Regional State, Ethiopia. This study aimed to determine the magnitude and bacterial profile of meningitis among newborns aged less than 90 days at Hawassa University Comprehensive Specialized Hospital (HUCSH). Methods A retrospective cross-sectional study was conducted among newborns under 90 days who were suspected of meningitis at HUCSH from January 2019 to July 2023, and for whom Cerebrospinal fluid (CSF) culture was performed. At HUCSH, bacteria are isolated and identified using standard microbiological techniques. Socio-demographic characteristics and culture results were extracted from the laboratory register. Data were entered into Excel and exported it to SPSS version 20 for analysis. Results Overall 1061 newborns suspected of meningitis were included in the study. Among the participants, 767 individuals (72.3%) fell within the age range of 8 to 90 days. Of the total participants, 437 (41.2%) were females. The magnitude of culture-confirmed meningitis was 90(8.5%) 95% CI: 6.8%−10.1%. The magnitude of culture-confirmed meningitis among newborns aged 0−7 days and 8−90 days were 1.6% and 6.9% respectively. The proportion of bacteria among newborns aged 0−7 days and 8−90 days were 18.9% and 81.1% respectively. Coagulase-negative Staphylococci (CONS) were the most common bacteria (n = 26; 28.9%) recovered followed by Acinetobacter species (n = 12, 13.3%), Escherichia coli (n = 9; 10%), and Klebsiella pneumoniae (n = 7; 7.8%). K. pneumoniae was the predominant bacteria among newborns within the age group of 0 to 7 days while Acinetobacter species was the most common among newborns within the 8 to 90 days age group. The prevalence of culture-confirmed neonatal meningitis was found to be greater in male newborns (x2 = 1.74, p = 0.18), newborns aged between 8 to 90 days (x2 = 0.07, p = 3.4), and newborns admitted in 2022 (x2 = 2.4, p = 0.66), Conclusions In this study, the overall magnitude of culture-confirmed meningitis was relatively high. Culture-confirmed meningitis was high in newborns within the age range of 8 to 90 days. The most common bacteria were CONS in both age groups followed by Acinetobacter species, E. coli, and K. pneumoniae.

ObjectivesDiagnostic prediction models exist to assess the probability of bacterial meningitis (BM) in paediatric patients with suspected meningitis. To evaluate the diagnostic accuracy of these models in a broad population of children suspected of a central nervous system (CNS) infection, we performed external validation. MethodsWe performed a systematic literature review in Medline to identify articles on the development, refinement or validation of a prediction model for BM, and validated these models in a prospective cohort of children aged 0–18 years old suspected of a CNS infection. Primary and secondary outcome measuresWe calculated sensitivity, specificity, predictive values, the area under the receiver operating characteristic curve (AUC) and evaluated calibration of the models for diagnosis of BM. ResultsIn total, 23 prediction models were validated in a cohort of 450 patients suspected of a CNS infection included between 2012 and 2015. In 75 patients (17%), the final diagnosis was a CNS infection including 30 with BM (7%). AUCs ranged from 0.69 to 0.94 (median 0.83, interquartile range [IQR] 0.79–0.87) overall, from 0.74 to 0.96 (median 0.89, IQR 0.82–0.92) in children aged ≥28 days and from 0.58 to 0.91 (median 0.79, IQR 0.75–0.82) in neonates. ConclusionsPrediction models show good to excellent test characteristics for excluding BM in children and can be of help in the diagnostic workup of paediatric patients with a suspected CNS infection, but cannot replace a thorough history, physical examination and ancillary testing.

Abstract Introduction Intracranial fungal infections’ (IcFIs) varying clinical manifestations lead to difficulties in diagnosis and treatment. African populations are disproportionately affected by the high burden of the disease. There is a lack of clarity as to the diagnostic and treatment modalities employed across the continent. In this review, we aim to detail the management, and outcome of IcFIs across Africa. Methods This scoping review was conducted using the Arksey and O\'Malley framework. MEDLINE, EMBASE, Cochrane Library, African Index Medicus, and African Journals Online were searched for relevant articles from database inception to August 10th, 2021. The Preferred Reporting Items for Systematic Review and Meta-Analysis extension for Scoping Reviews guidelines were used to report the findings of the review. Results Of the 5,779 records identified, 131 articles were included. The mean age was 35.6 years, and the majority (56.4%) were males. The majority (n = 8,433/8,693, 97.0%) of IcFIs presented as a meningitis, the most common communicable predisposing factor of IcFIs was HIV/AIDS (n = 7,815/8,693, 89.9%), and the most common non-communicable risk factor was diabetes mellitus (n = 32/8,693, 0.4%). Cryptococcus species was the most common (n = 8,428/8,693, 97.0%) causative organism. The most commonly used diagnostic modality was cerebrospinal (CSF) cultures (n = 4,390/6,830, 64.3%) for diffuse IcFIs, and MRI imaging (n = 12/30, 40%) for focal IcFIs. The most common treatment modality was medical management with antifungals only (n = 4,481/8,693, 51.6%). The most commonly used antifungal agent in paediatric, and adult patients was amphotericin B and fluconazole dual therapy (51.5% vs 44.9%). The overall mortality rate was high (n = 3,475/7,493, 46.3%), and similar for both adult and paediatric patients (47.8% vs 42.1%). Conclusion Most IcFIs occurred in immunosuppressed individuals, and despite the new diagnostic techniques, CSF culture was mostly used in Africa. Antifungals regimens used was similar between children and adults. The outcome of IcFIs in Africa was poor for both paediatric and adult patients.

Abstract Background Cryptococcal meningitis is a leading cause of AIDS-related mortality. Cryptococcal antigen (CrAg) predicts the development of meningitis. Historically, despite standard- of-care fluconazole, 25%–30% of asymptomatic CrAg-positive persons develop breakthrough meningitis or death. We evaluated whether adding single high-dose liposomal amphotericin B to standard pre-emptive fluconazole therapy could improve meningitis-free survival.Methods Participants with human immunodeficiency virus (HIV) and asymptomatic cryptococcal antigenemia in Uganda were randomized to liposomal amphotericin B (10 mg/kg once) with fluconazole or fluconazole alone through 24 weeks. We compared 24-week, meningitis-free survival time between treatment groups. After the second interim review, the Data Safety and Monitoring Board recommended no further enrollment of participants with low plasma CrAg lateral flow assay titers (≤1:80) due to futility. Herein, we present the results of participants with low plasma CrAg titers.Results 168 participants enrolled into the ACACIA trial had low plasma CrAg titers (≤1:80). During 24 weeks of follow-up, meningitis or death occurred in 14.5% (12/83) of participants randomized to liposomal amphotericin B with fluconazole versus 10.6% (9/85) assigned to fluconazole alone (hazard ratio, 1.42; 95% CI, .60–3.36; P = .431). Adverse events were more frequent in participants assigned to the intervention versus standard-of-care (28% vs 12%; P = .011).Conclusions Among CrAg-positive persons with low titers (≤1:80), the addition of single-dose liposomal amphotericin B to fluconazole as pre-emptive therapy provided no additional clinical benefit. This trial provides supportive evidence that, in asymptomatic populations with low plasma CrAg titers, lumbar punctures are likely unnecessary as administration of meningitis treatment did not improve outcomes.Clinical Trials Registration Clinicaltrials.gov (NCT03945448).

Abstract Follow-up of previously healthy patients surviving cryptococcal meningitis found that cryptococcal antigen could be detected for more than one year in serum from 38 of 44 (86%) patients and in CSF from 20 of 31 patients (67%), far beyond the time of culture conversion. The speed of titer decline, measured as the number of days for a two fold drop in titer to occur, was slower in serum than in CSF. Speed of decline of antigen titers was much slower in serum and CSF for patients infected with C. gattii than C. neoformans. The speed of decline in CSF and serum titers was also much slower in patients who had received a ventriculoperitoneal shunt for increased intracranial pressure. The variable and extraordinarily slow rate of clearance in our patients did not appear to reflect differences in disease control but rather differences in species and shunting for increased intracranial pressure.

Abstract Background Leprosy is a chronic infectious disease caused by Mycobacterium leprae (M. leprae) that is responsible for deformities and irreversible peripheral nerve damage and has a broad spectrum of clinical and serological manifestations. Leprosy primarily affects the peripheral nerves and rarely presents with central nervous system involvement. Diagnosing leprosy can still be difficult in some cases, especially when the infection involves uncommon clinical manifestations and extracutaneous sites. Delayed diagnosis and treatment of leprosy may lead to irreversible damage and death. Case Presentation We report a case of a 30-year-old female presenting with “repeated high fever with symptoms of headache for 14 days”. On the day of admission, physical signs of lost eyebrows and scattered red induration patches all over her body were observed. The patient’s diagnosis was based on the clinical characteristics using a combination of metagenomic next-generation sequencing (mNGS) of cerebrospinal fluid (CSF) and slit-skin smear. After confirming Listeria meningitis and multibacillary leprosy with erythema nodosum leprosum (ENL), a type 2 reaction, she was treated with ampicillin sodium, dapsone, rifampicin, clofazimine, methylprednisolone, and thalidomide. At the 1-year follow-up, the frequency and severity of headaches have significantly decreased and a good clinical response with improved skin lesions was found. Conclusion This case highlights the importance of considering leprosy, which is a rare and underrecognized disease, in the differential diagnosis of skin rashes with rheumatic manifestations, even in areas where the disease is not endemic, and physicians should be alerted about the possibility of central nervous system infections. In addition, mNGS can be used as a complementary diagnostic tool to traditional diagnostic methods to enhance the diagnostic accuracy of leprosy.

Abstract Objective To investigate risk factors associated with long-term mortality in patients with stage II and III tuberculous meningitis (TBM). Methods This retrospective analysis examined patients who were first diagnosed with stage II and III TBM at West China Hospital of Sichuan University between January 1, 2018 and October 1, 2019. Patients were followed via telephone and categorized into survival and mortality groups based on 4-year outcomes. Multivariate logistic regression identified independent risk factors for long-term mortality in stage II and III TBM. Results In total, 178 patients were included, comprising 108 (60.7%) males and 36 (20.2%) non-survivors. Mean age was 36 ± 17 years. Compared to survivors, non-survivors demonstrated significantly higher age, heart rate, diastolic blood pressure, blood glucose, rates of headache, neurological deficits, cognitive dysfunction, impaired consciousness, hydrocephalus, and basal meningeal inflammation. This group also exhibited significantly lower Glasgow Coma Scale (GCS) scores, blood potassium, albumin, and cerebrospinal fluid chloride. Multivariate analysis revealed age (OR 1.042; 95% CI 1.015–1.070; P = 0.002), GCS score (OR 0.693; 95% CI 0.589–0.814; P

Abstract Background Limited data exist on the antifungal activity of daily liposomal amphotericin B with flucytosine induction regimens for cryptococcal meningitis, which are recommended in high-income countries. Liposomal amphotericin B monotherapy at 3 mg/kg previously failed to meet non-inferiority criteria compared to amphotericin B deoxycholate in its registrational clinical trial. We aimed to compare the quantitative antifungal activity and mortality between daily amphotericin B deoxycholate and daily liposomal amphotericin among persons with HIV-related cryptococcal meningitis receiving adjunctive flucytosine 100 mg/kg/day.Methods We analyzed data from three clinical studies involving participants with HIV-associated cryptococcal meningitis receiving either daily liposomal amphotericin B at 3 mg/kg/day with flucytosine (N = 94) or amphotericin B deoxycholate at 0.7–1.0 mg/kg/day with flucytosine (N = 404) as induction therapy. We compared participant baseline characteristics, CSF early fungicidal activity (EFA), and 10-week mortality.Results We included 498 participants in this analysis, of whom 201 had available EFA data (N = 46 liposomal amphotericin; N = 155 amphotericin deoxycholate). Overall, there is no statistical evidence that the antifungal activity of liposomal amphotericin B (mean EFA = 0.495 log10 CFU/mL/day; 95%CI, 0.355–0.634) differ from amphotericin B deoxycholate (mean EFA = 0.402 log10 CFU/mL; 95%CI, 0.360–0.445) (P = 0.13). Mortality at 10 weeks trended lower for liposomal amphotericin (28.2%) vs amphotericin B deoxycholate (34.6%) but was not statistically different when adjusting for baseline characteristics (adjusted Hazard Ratio = 0.74; 95%CI, 0.44–1.25; P = 0.26).Conclusions Daily liposomal amphotericin B induction demonstrated a similar rate of CSF fungal clearance and 10-week mortality as amphotericin B deoxycholate when combined with flucytosine for the treatment of HIV-associated cryptococcal meningitis.

DesignSingle-centre retrospective study. SettingThe Tuberculosis Diagnosis and Treatment Center of Zhejiang Chinese and Western Medicine Integrated Hospital. ParticipantsWe enrolled 64 adult patients with presumptive TBM admitted to our hospital from August 2021 to August 2023. MethodsWe calculated the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of AFB smear, culture, Xpert MTB/RIF and nanopore sequencing to evaluate their diagnostic efficacy compared with a composite reference standard for TBM. ResultsAmong these 64 patients, all tested negative for TBM by AFB smear. The sensitivity, specificity, PPV and NPV were 11.11%, 100%, 100% and 32.2% for culture, 13.33%, 100%, 100% and 2.76% for Xpert MTB/RIF, and 77.78%, 100%, 100% and 65.52% for nanopore sequencing, respectively. ConclusionThe diagnostic accuracy of the nanopore sequencing test was significantly higher than that of conventional testing methods used to detect TBM.

Tick-borne encephalitis (TBE) virus is a major flavivirus causing central nervous system (CNS) infections in Europe [1,2] and is also endemic in many parts of Asia [1]. The European TBE virus subtype generally causes milder disease than Asian subtypes and will be the focus of this study. In symptomatic cases, TBE presents as meningitis (40-50%), meningoencephalitis (50%), or meningoencephalomyelitis (10%) [1,3,4]. The most common clinical signs of parenchymal CNS involvement in TBE are altered consciousness, ataxia, tremor, and muscle paralysis [3,4].

Abstract Purpose To investigate clinical characteristics and outcomes of patients with pneumococcal meningitis during the COVID-19 pandemic. Methods In a Dutch prospective cohort, risk factors and clinical characteristics of pneumococcal meningitis episodes occurring during the COVID-19 pandemic (starting March 2020) were compared with those from baseline and the time afterwards. Outcomes were compared with an age-adjusted logistic regression model. Results We included 1,699 patients in 2006–2020, 50 patients in 2020–2021, and 182 patients in 2021–2023. After March 2020 relatively more alcoholism was reported (2006–2020, 6.1%; 2020–2021, 18%; 2021–2023, 9.7%; P = 0.002) and otitis–sinusitis was less frequently reported (2006–2020, 45%; 2020–2021, 22%; 2021–2023, 47%; P = 0.006). Other parameters, i.e. age, sex, symptom duration or initial C-reactive protein level, remained unaffected. Compared to baseline, lumbar punctures were more frequently delayed (on admission day, 2006–2020, 89%; 2020–2021, 74%; 2021–2022, 86%; P = 0.002) and outcomes were worse (‘good recovery’, 2020–2021, OR 0.5, 95% CI 0.3–0.8). Conclusion During the COVID-19 pandemic, we observed worse outcomes in patients with pneumococcal meningitis. This may be explained by differing adherence to restrictions according to risk groups or by reduced health care quality.

After March 2020 relatively more alcoholism was reported (2006–2020, 6.1%; 2020–2021, 18%; 2021–2023, 9.7%; P = 0.002) and otitis–sinusitis was less frequently reported (2006–2020, 45%; 2020–2021, 22%; 2021–2023, 47%; P = 0.006). Other parameters, i.e. age, sex, symptom duration or initial C-reactive protein level, remained unaffected. Compared to baseline, lumbar punctures were more frequently delayed (on admission day, 2006–2020, 89%; 2020–2021, 74%; 2021–2022, 86%; P = 0.002) and outcomes were worse (‘good recovery’, 2020–2021, OR 0.5, 95% CI 0.3–0.8). Conclusion During the COVID-19 pandemic, we observed worse outcomes in patients with pneumococcal meningitis. This may be explained by differing adherence to restrictions according to risk groups or by reduced health care quality.

Abstract Background and objectives Central nervous system infections, typified by bacterial meningitis, stand as pivotal emergencies recurrently confronted by neurologists. Timely and precise diagnosis constitutes the cornerstone for efficacious intervention. The present study endeavors to scrutinize the influence of inflammatory protein levels associated with neutrophils in cerebrospinal fluid on the prognosis of central nervous system infectious maladies. Methods This retrospective case series study was undertaken at the Neurology Department of the Second Hospital of Shandong University, encompassing patients diagnosed with infectious encephalitis as confirmed by PCR testing and other diagnostic modalities spanning from January 2018 to January 2024. The quantification of MPO and pertinent inflammatory proteins within patients’ cerebrospinal fluid was accomplished through the utilization of ELISA. Results We enlisted 25 patients diagnosed with bacterial meningitis, ascertained through PCR testing, and stratified them into two groups: those with favorable prognoses (n = 25) and those with unfavorable prognoses (n = 25). Following assessments for normality and variance, notable disparities in CSF-MPO concentrations emerged between the prognostic categories of bacterial meningitis patients (P
