The Need for European Surveillance of CDI.

Since the turn of the millennium, the epidemiology of Clostridioides difficile infection (CDI) has continued to challenge. Changes in clinical presentation, severity of disease, descriptions of new risk factors and the occurrence of outbreaks all emphasised the importance of early diagnosis and standardised surveillance systems. However, a lack of consensus on case definitions, clinical guidelines and optimal laboratory diagnostics across Europe has led to the underestimation of CDI and impeded comparison between countries. These inconsistencies have prevented the true burden of disease from being appreciated.Acceptance that a multi-country CDI surveillance program and optimised diagnostic strategies are required has built the foundations for a more robust, unified surveillance. The concerted efforts of the European Centre for Disease Prevention and Control (ECDC) CDI networks led to the development of the European surveillance protocol and an over-arching long-term CDI surveillance strategy for 2014-2020, which has been followed by the development of surveillance systems in at least 20 European countries. However, surveillance activities in individual countries have slowed during the COVID-19 pandemic as resources were diverted to the global health crisis. A renewed and strengthened focus on CDI surveillance and prevention is therefore urgently needed post COVID-19.

Five-year review of ocular Neisseria gonorrhoeae infections presenting to ophthalmology departments in Greater Glasgow & Clyde, Scotland.

INTRODUCTION: As gonococcal infections continue to increase, we wanted to review the number and clinical course of recent ocular gonococcal cases presenting to ophthalmology departments in NHS Greater Glasgow and Clyde. METHODS: A 5-year retrospective review of adult ocular gonococcal cases, where the diagnosis of Neisseria gonorrhoeae was made on microbiological culture, was undertaken. RESULTS: Fifteen cases were identified (80% male). Average age was 26 years (range 17-42; median 24). Most common presenting features included purulent discharge (14/15; 93%), haemorrhagic conjunctivitis (10/15; 67%) and pre-septal cellulitis (9/15; 60%). Corneal involvement was documented in 5 (33%), with marginal ulceration in 1 (7%) but none had corneal perforation. Most common systemic treatment was IV ceftriaxone, alone or in combination with another antibiotic (6/15; 40%), followed by IM ceftriaxone, alone or in combination with another antibiotic (5/15; 33%). Median time from presentation to treatment was 1 day (0-23). All patients were referred or recommended to attend sexual health services. Seven patients (47%) attended and received complete sexually transmitted infection (STI) testing and contact tracing: 3 patients had systemic treatment initiated or changed at this visit and 1 patient had concurrent syphilis identified. CONCLUSIONS: This series confirms purulent conjunctivitis and cellulitis as the main presenting features of ocular gonococcal infection requiring hospital review. Early identification with appropriate systemic antibiotic treatment avoided corneal melting in this cohort. As concurrent STIs were identified and/or treatments changed in 4/7 (57%) following sexual health review, we recommend a shared care approach between ophthalmology, microbiology and sexual health services to effectively address all management issues.

Lessons from an Educational Invasive Fungal Disease Conference on Hospital Antifungal Stewardship Practices across the UK and Ireland.

Invasive fungal disease (IFD) is a growing health burden. High mortality rates, increasing numbers of at-risk hosts, and a limited availability of rapid diagnostics and therapeutic options mean that patients are increasingly exposed to unnecessary antifungals. High rates of prescriptions promote patient exposure to undue toxicity and drive the emergence of resistance. Antifungal stewardship (AFS) aims to guide antifungal usage and reduce unnecessary exposure and antifungal consumption whilst maintaining or improving outcomes. Here, we examine several AFS approaches from hospitals across the UK and Ireland to demonstrate the benefits of AFS practices and support the broader implementation of AFS as both a necessary and achievable strategy. Since the accuracy and turnaround times (TATs) of diagnostic tools can impact treatment decisions, several AFS strategies have included the development and implementation of diagnostic-driven care pathways. AFS informed treatment strategies can help stratify patients on a risk basis ensuring the right patients receive antifungals at the optimal time. Using a multidisciplinary approach is also key due to the complexity of managing and treating patients at risk of IFD. Through knowledge sharing, such as The Gilead Antifungal Information Network (GAIN), we hope to drive practices that improve patient management and support the preservation of antifungals for future use.

A 20-year observational cohort of a 5 million patient population-Tonsillectomy rates in the context of two national policy changes.

AIM: (a) To report national trends for tonsillectomy, tonsillitis, peritonsillar abscess and deep neck space infection in secondary care. (b) To report national trends in sore throat consultations in primary care. (c) To report national trends in antibiotic prescribing in both primary and secondary care between 2011 and 2015. DESIGN: Retrospective nationwide cohort study. Data requested from Information Statistics Department (ISD) Scotland for tonsillectomy, tonsillitis admissions, peritonsillar abscess admissions and deep neck space infection (DNSI) admissions in Scotland, between 1993/94 and 2015/16. Data for antibiotic prescriptions in general practice and hospital admissions between 2011 and 2015. SETTING: Scottish ENT departments and GP practices. PARTICIPANTS: Scottish patients who underwent tonsillectomy or were admitted to hospital with tonsillitis, peritonsillar abscess or deep neck space infection. Scottish patients that attended their GP with tonsillitis. RESULTS: Tonsillectomy rates between 1993/94 and 2015/16 decreased by 48% (P < 0.001). Over the same time period, there has been a corresponding 136% increase in tonsillitis admission (P < 0.001) and a 167% increase in peritonsillar abscess admissions, (P < 0.001). Between 1996/97 and 2015/16, there was a 500% increase in deep neck space abscesses (P < 0.001). CONCLUSION: There has been a significant decrease in tonsillectomy rates over the past two decades. Over the same time period, there has been a significant increase in admissions to secondary care with tonsillitis, peritonsillar abscess and deep neck space infection. These changes have happened in the context of two separate national policies being introduced-Scottish Intercollegiate Guideline Network (SIGN) guidelines for management of sore throat and the Scottish Reduction in Antibiotic Prescribing.

The Need for European Surveillance of CDI.

Since the turn of the millennium, the epidemiology of Clostridium difficile infection (CDI) has continued to challenge. Over the last decade there has been a growing awareness that improvements to surveillance are needed. The increasing rate of CDI and emergence of ribotype 027 precipitated the implementation of mandatory national surveillance of CDI in the UK. Changes in clinical presentation, severity of disease, descriptions of new risk factors and the occurrence of outbreaks all emphasised the importance of early diagnosis and surveillance.However a lack of consensus on case definitions, clinical guidelines and optimal laboratory diagnostics across Europe has lead to the underestimation of CDI and impeded comparison between countries. These inconsistencies have prevented the true burden of disease from being appreciated.Acceptance that a multi-country surveillance programme and optimised diagnostic strategies are required not only to detect and control CDI in Europe, but for a better understanding of the epidemiology, has built the foundations for a more robust, unified surveillance. The concerted efforts of the European Centre for Disease Prevention and Control (ECDC) CDI networks, has lead to the development of an over-arching long-term CDI surveillance strategy for 2014-2020. Fulfilment of the ECDC priorities and targets will no doubt be challenging and will require significant investment however the hope is that both a national and Europe-wide picture of CDI will finally be realised.

Schistosomiasis in Scottish travellers: public health importance of laboratory testing and the need for enhanced surveillance.

Background: Imported schistosomiasis is of significant public health importance and is likely to be underestimated since infection is often asymptomatic. We describe data from travellers residing in Scotland which includes a subset of group travellers from one of the largest Health Boards in Scotland. Methods: Clotted bloods were obtained during the period 2001-15 from a total of 8163 Scottish travellers. This included seven groups comprising of 182 travellers. Sera were examined for the presence of Schistosome species antibody at the Scottish Parasite Diagnostic and Reference Laboratory (SPDRL). Results: Of all, 25% (n = 1623) tested positive with 40% (n = 651) of those patients aged between 20 and 24 years. Although 62% (n = 1006) of those who tested positive reported travel to Africa, important information on the specific region visited was lacking in almost one-third of samples received. Overall, 62 (34%) of group travellers tested positive and 95% (n = 59) reporting travel to Africa. Conclusions: Globalization, affordable air travel and improved awareness, are likely to contribute towards the increasing number of imported schistosomiasis cases. Therefore, enhanced surveillance capturing detailed travel history and fresh water exposures will improve risk stratification, pre-travel advice and optimize testing and treatment regimes for this increasingly important parasitic disease.
