Cross-border spread of blaNDM-1- and blaOXA-48-positive Klebsiella pneumoniae: a European collaborative analysis of whole genome sequencing and epidemiological data, 2014 to 2019

An alert regarding an outbreak of carbapenem-resistant Klebsiella pneumoniae carrying bla NDM-1 and bla OXA-48 carbapenemase-encoding genes was sent by Germany to European Union (EU)/European Economic Area (EEA) countries in October 2019. Since only limited whole genome sequencing (WGS) data on bla NDM-1- and bla OXA-48-positive K. pneumoniae were available in the public domain, national public health reference or equivalent expert laboratories from EU/EEA countries were invited to share WGS data from their national collections with the European Centre for Disease Prevention and Control (ECDC) to investigate the international dissemination of this epidemic strain. The analysis identified a Finnish case with an isolate closely related to the German outbreak strain and with an epidemiological link to St. Petersburg, Russia. In addition, several other clusters of genetically related bla NDM-1- and bla OXA-48-positive K. pneumoniae unrelated to the German outbreak strain but affecting numerous EU/EEA countries were identified. The aim of this follow-up investigation was to characterise these clusters based on the integrated analysis of the WGS dataset on bla NDM-1 - and bla OXA-48-positive K. pneumoniae submitted from 13 EU/EEA countries and additional epidemiological data

Candida auris: epidemiological situation, laboratory capacity and preparedness in the European Union and European Economic Area*, January 2018 to May 2019.

Between January 2018 and May 2019, 349 cases of Candida auris were reported in the European Union/European Economic Area*, 257 (73.6%) colonisations, 84 (24.1%) bloodstream infections, seven (2.0%) other infections and one case of unknown infection/colonisation status (0.3%). Most cases (97.1%, n = 339) were reported from Spain or the United Kingdom, but also for the first time in Greece, the Netherlands and Poland. Laboratory capacity and preparedness has improved since January 2018

Haemolysis associated with the treatment of malaria with artemisinin derivatives: a systematic review of current evidence

Background: Artemisinin derivatives are the mainstay of antimalarial treatment, both for uncomplicated malaria and for severe disease. Artemisinins are known for their rapid onset of action, good tolerability, and safety. However, besides the sporadic but worrying reports of delayed parasite clearance after treatment with artemisinins, there have been an increasing number of reports of acute haemolytic anaemia following their use and the safety of this class of antimalarials is being questioned. Methods: In this systematic review, all reports of patients experiencing haemolysis following the use of artemisinins for the treatment of malaria were identified and collated into an electronic database. Summary statistics were calculated to characterize the epidemiology and clinical features of this safety concern related to artemisinin derivatives. Results: A total of 37 patients were identified suffering from haemolysis following the treatment of severe malaria with artemisinin derivatives. Thirty-one cases had received intravenous artesunate, while the remaining cases were attributed to other parenteral or oral regimens of artemisinin derivatives. The majority of patients were returning travellers (n = 30), and six clinical cases had been reported in paediatric patients. The median onset of haemolysis was 15 (interquartile range (IQR) 13–15) days after the initiation of treatment for the ‘delayed-onset’ pattern and 17 (IQR 13–22) days for the ‘persistent’ haemolysis pattern. The median reduction in haemoglobin due to haemolysis was 6 g/dl (IQR 4–8 g/dl). The estimated proportion of patients suffering from severe malaria experiencing haemolysis after treatment with artemisinin derivatives was 13% (95% confidence interval 9–18%), and 73% of these (i.e., 9% of the total population) required blood transfusions. No fatal outcome has been reported in the literature to date. Conclusions: Haemolysis is commonly associated with the class of artemisinin drugs when used for the treatment of severe malaria. Potential causes of this safety issue are discussed. Although no deaths attributed to haemolysis have been reported so far, this safety issue may lead to life-threatening anaemia and is particularly worrying for regions where safe blood products are not readily available

Toxocariasis in humans in Africa - A systematic review

Background: Toxocariasis is a globally distributed zoonosis. The most important definitive hosts are dogs, whereas humans serve as paratenic hosts. Transmission to humans occurs by accidental ingestion of eggs, e.g. by consumption of contaminated fruits or vegetables. Although exposure to Toxocara is usually considered as relatively benign, it is implicated in a range of neurological, ophthalmologic and other organ-specific conditions, some of them with grave consequences. This review provides an overview on the epidemiology, presentation and risk factors of exposure to Toxocara in Africa. Methods: A systematic search was performed for studies published after January 1st, 1990, in English, French, Portuguese, Spanish, Dutch or German. The review was prepared according to PRISMA guidelines. Studies on toxocariasis in human populations and contamination in human environments were included. Results: Sixty-five papers were included. Antibodies against Toxocara spp. in humans were found to be very common across Africa. Severe manifestations have been reported mainly from North Africa. Environmental contamination including soil, vegetables and fruits sold on markets was demonstrated in various locations in Africa. Conclusions: Exposure to Toxocara is prevalent across the African continent. However, the complication frequency, the impact of the condition on the individual and the public health relevance of this zoonosis, and the economic impact have never been systematically evaluate

Neuropsychological long-term sequelae of Ebola virus disease survivors - A systematic review

The recent West African Ebola virus disease (EVD) outbreak had catastrophic impact on populations, health care systems and economies of the affected countries. Somatic symptoms have been reported to persist long beyond the acute infection. This review was conducted to provide an overview on neuro- and socio-psychological long-term sequelae of EVD survivors. Utilizing Pubmed and PsycInfo databases, a systematic review prepared according to PRISMA guidelines. Only studies reporting quantitative data on neuropsychological sequelae three weeks or later after discharge from the Ebola-treating unit were included. Pooled proportions of common outcomes were calculated. In total, 224 papers were identified, of which 10 were included. Depression, insomnia, fatigue, anxiety and post-traumatic stress were common sequelae in EVD survivors. However, data from high-quality studies were scarce. EVD survivors have been thought to commonly face neuropsychological long-term sequelae. Methodological drawbacks and heterogeneity of current studies limit conclusions of the impact and magnitude of such sequelae. We advocate the preparation of a prospective, controlled cohort study protocol in preparation for a future outbrea

Epidemiological situation, laboratory capacity and preparedness for carbapenem-resistant Acinetobacter baumannii in Europe, 2019

International audienceTo update information on the epidemiological situation and national capacity for detection, surveillance and containment of carbapenem-resistant Acinetobacter baumannii (CRAb) in Europe, we performed a survey in 37 countries. Nine countries reported regional or inter-regional spread and seven an endemic situation. Laboratories with a reference function, surveillance systems, and a national containment plan for CRAb existed in 30, 23 and eight countries, respectively. A pan-European molecular survey would provide in-depth understanding of the CRAb epidemiology
