Epidemiology of invasive meningococcal disease in Cyprus 2004 to 2018.

ABSTRACT: BackgroundDespite progress in the management of invasive meningococcal disease (IMD) it causes significant mortality and sequelae.AimThis study aims to describe the epidemiology and clinical characteristics of IMD in Cyprus and discuss the current immunisation programmes.MethodsThis is a retrospective study of all cases of IMD notified to the Ministry of Health between 2004 and 2018. Demographic, epidemiological, clinical and microbiological data were collected when a new case was notified. Risk factors associated with mortality were investigated using univariable logistic regression.Results54 cases of IMD were recorded, an overall incidence of 0.4 cases per 100,000 population. The incidence rate was highest among infants (7.2/100,000) and adolescents (1.4/100,000). Case fatality rate was 10.4%. Serogroup B accounted for 24 of 40 cases caused by known serogroup. Serogroups W and Y comprised nine cases and were responsible for most fatal cases. Serogroup C was the cause in only four cases. There was an increase in the odds of death with increasing age, while the presence of meningitis in the clinical picture was found to be associated with lower odds of death.ConclusionDespite the low incidence of IMD in Cyprus, it remains an important cause of morbidity and mortality. Serogroup B is the most frequent serogroup, while incidence of serogroups W and Y is rising. Monitoring new cases and yearly evaluation of the immunisation programmes by the National Immunization Technical Advisory Group (NITAG) is essential for successful control of the disease.

Project description:BackgroundInvasive meningococcal disease (IMD) represents a global health burden. However, its epidemiology in the Eastern Mediterranean (EM) and North Africa (NA) regions is currently not well understood. This review had four key objectives: to describe asymptomatic meningococcal carriage, IMD epidemiology (e.g. serogroup prevalence, case-fatality rates [CFRs]), IMD presentation and management (e.g. clinical diagnosis, antibiotic treatments) and economic impact and evaluation (including health technology assessment [HTA] recommendations) in EM and NA.MethodsA systematic literature search (MEDLINE and EMBASE) was conducted (January 2000 to February 2021). Search strings included meningococcal disease and the regions/countries of interest. Identified publications were screened sequentially by title/abstract, followed by screening of the full-text article; articles were also assessed on methodological quality. Literature reviews, genetic sequencing or diagnostic accuracy studies, or other non-pertinent publication type were excluded. An additional grey literature search (non-peer-reviewed sources; start date January 2000) was conducted to the end of April 2019.ResultsOf the 1745 publications identified, 79 were eligible for the final analysis (n = 61 for EM and n = 19 for NA; one study was relevant to both). Asymptomatic meningococcal carriage rates were 0-33% in risk groups (e.g. military personnel, pilgrims) in EM (no data in NA). In terms of epidemiology, serogroups A, B and W were most prevalent in EM compared with serogroups B and C in NA. IMD incidence was 0-20.5/100,000 in EM and 0.1-3.75/100,000 in NA (reported by 7/15 countries in EM and 3/5 countries in NA). CFRs were heterogenous across the EM, ranging from 0 to 57.9%, but were generally lower than 50%. Limited NA data showed a CFR of 0-50%. Data were also limited in terms of IMD presentation and management, particularly relating to clinical diagnosis/antibiotic treatment. No economic evaluation or HTA studies were found.ConclusionsHigh-risk groups remain a significant reservoir of asymptomatic meningococcal carriage. It is probable that inadequacies in national surveillance systems have contributed to the gaps identified. There is consequently a pressing need to improve national surveillance systems in order to estimate the true burden of IMD and guide appropriate prevention and control programmes in these regions.
