Tsang RSW, Deceuninck G, Meilleur C, Zhou J, Lefebvre B, De Wals P. Temporal variations in the serogroup distribution of invasive meningococcal disease in Quebec, Canada, due to emerging unique clade of serogroup Y strain belonging to the Sequence Type-23 clonal complex. J Infect 2024; 88:106163. [PMID: 38670267 DOI: 10.1016/j.jinf.2024.106163] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Revised: 04/11/2024] [Accepted: 04/17/2024] [Indexed: 04/28/2024]
Abstract
OBJECTIVE To identify recent trends in invasive meningococcal diseases (IMD) in Quebec, Canada, with a focus on MenY cases and MenY strains. METHODS IMD cases and MenY strains from January 1, 2015 to August 11, 2023 were analyzed for clonal analysis and prediction of susceptibility to MenB vaccines. MenY strains of ST-23 CC from Quebec were analyzed with global MenY strains by core-genomic multi-locus sequence typing (cg-MLST). RESULTS Since 2015 the serogroup distribution of IMD in Quebec has shifted from predominantly MenB to mainly MenY, with most (80.9 %) of the latter belonging to ST-23 CC. The median age of MenY cases due to ST-23 CC were statistically younger than MenY cases due to non-ST-23 CC. MenY of ST-23 CC showed genetic diversity and the major genetic cluster were similar to the Swedish Y1 strain. The increase in invasive MenY disease in Quebec was due to a sub-clade of Lineage 23.1 which caused an elevated proportion of severe disease in young adults. CONCLUSION The increase in invasive MenY disease in Quebec, Canada was driven by the expansion of a sub-clade of Lineage 23.1 in young adults. Currently available quadrivalent A,C,W,Y-conjugate meningococcal vaccines were predicted to provide protection against these strains.

Leong LE, Coldbeck-Shackley RC, McMillan M, Bratcher HB, Turra M, Lawrence A, Kahler C, Maiden MC, Rogers GB, Marshall H. The genomic epidemiology of Neisseria meningitidis carriage from a randomised controlled trial of 4CMenB vaccination in an asymptomatic adolescent population. THE LANCET REGIONAL HEALTH. WESTERN PACIFIC 2024; 43:100966. [PMID: 38169944 PMCID: PMC10758868 DOI: 10.1016/j.lanwpc.2023.100966] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 10/18/2023] [Accepted: 11/01/2023] [Indexed: 01/05/2024]
Abstract
Background Oropharyngeal carriage of Neisseria meningitidis is frequent during adolescence, representing a major source of invasive meningococcal disease. This study examined the impact of a serogroup B vaccination (Bexsero, GSK 4CMenB) programme on adolescent N. meningitidis carriage using genomic data. Methods A total 34,489 oropharyngeal samples were collected as part of a state-wide cluster randomised-controlled trial in South Australia during 2017 and 2018 (NCT03089086). Samples were screened for the presence of N. meningitidis DNA by porA PCR prior to culture. Whole genome sequencing was performed on all 1772 N. meningitidis culture isolates and their genomes were analysed. Findings Unencapsulated meningococci were predominant at baseline (36.3% of isolates), followed by MenB (31.0%), and MenY (20.5%). Most MenB were ST-6058 from hyperinvasive cc41/44, or ST-32 and ST-2870 from cc32. For MenY, ST-23 and ST-1655 from cc23 were prevalent. Meningococcal carriage was mostly unchanged due to the vaccination programme; however, a significant reduction in ST-53 capsule-null meningococci prevalence was observed in 2018 compared to 2017 (OR = 0.52; 95% CI: 0.30-0.87, p = 0.0106). This effect was larger in the vaccinated compared to the control group (OR = 0.37; 95% CI: 0.12-0.98, p = 0.0368). Interpretation While deployment of the 4CMenB vaccination did not alter the carriage of hyperinvasive MenB in the vaccinated population, it altered the carriage of other N. meningitidis sequence types following the vaccination program. Our findings suggest 4CMenB vaccination is unlikely to reduce transmission of hyperinvasive N. meningitidis strains and therefore ongoing targeted vaccination is likely a more effective public health intervention.

Abstract
INTRODUCTION Invasive meningococcal disease (IMD) due to serogroup W meningococci (MenW) is consistently reported with atypical clinical manifestations, including gastrointestinal symptoms, bacteremic pneumonia, and septic arthritis. We undertook a systematic review of the literature for a comprehensive assessment of the clinical presentation of IMD caused by MenW. METHODS PubMed and Embase databases were searched from inception to June 2022 using a combination of MeSH terms and free text for articles that reported symptoms and signs of MenW IMD, and associated manifestations. RESULTS The most commonly reported symptoms identified included: fever (range 36-100% of cases), nausea and/or vomiting (range 38-47%), vomiting (range 14-68%), cough (range 7-57%), sore throat (range 13-34%), headache (range 7-50%), diarrhea (range 8-47%), altered consciousness/mental status (range 7-38%), stiff neck (range 7-54%), and nausea (range 7-20%). Sepsis (range 15-83% of cases) was the most commonly reported manifestation followed by meningitis (range 5-72%), sepsis and meningitis (range 6-74%), bacteremic pneumonia (range 4-24%), arthritis (range 1-15%), and other manifestations (e.g., pharyngitis/epiglottitis/supraglottitis/tonsillitis/conjunctivitis; range 1-24%). The case fatality rates ranged from 8-40%, and among the survivors 4-14% had long-term sequelae. CONCLUSIONS Clinicians need to be aware of the nonspecific symptoms and signs of IMD, as well as of the atypical manifestations in regions where MenW is known to circulate to ensure timely diagnoses and treatment.

Abstract
Waterhouse-Friderichsen syndrome (WFS), defined as severe adrenal insufficiency due to bilateral adrenal gland haemorrhagic necrosis, occurred in a 59-year-old woman. An underlying serogroup Y Neisseria meningitidis (NM) infection was diagnosed, with a rapid progression to purpura fulminans, disseminated intravascular coagulation and WFS. Intensive treatment including fluid resuscitation, broad-spectrum antibiotic therapy, ventilatory support, platelet and factor replacement were administered. The meningococcaemia in the presence of WFS had a fulminant progression, leading to a fatal outcome within 24 hours of symptom onset. This case details the diagnosis and management challenges of the WFS, a rare complication of NM septicaemia, and describes the identification of a NM serogroup that is rare in Portugal in middle-aged patients.
