Clostridium difficile infection (CDI),  a potentially fatal disease,  is one
of the most common healthcare acquired infections ^[1]

Today marks the launch of the EU ropean, multi-centre, prospective bi-annual
point prevalence study of CL ostridium difficile  I nfection in hospitalised
patients with D iarrhoea (EUCLID), the largest study of the prevalence of CDI
ever conducted in Europe. For the first time experts will get a clear picture
of the true incidence of CDI; a significant cause of morbidity and mortality
and a condition that is thought to be widely under-estimated. ^[2] ^, ^[3]

CDI is the leading cause of infectious diarrhoea in industrialised countries
^[4] and is estimated to kill one in 50 patients affected. ^[3] CDI
represents a huge economic burden, ^[5] patients who develop CDI stay in
hospital an extra 1-3 weeks ^[5] ^, ^[6] ^, ^[7] at an estimated additional
cost of €7,147 ^[5] compared to those without CDI. The incidence and severity
of CDI continues to increase. ^[3] ^, ^[8] ^, ^[9] ^, ^[10] ^, ^[11] The most
recent large-scale prevalence study was carried out in Spain in 2008 and
looked at the number of CDI cases within the general population at a certain
time. Results revealed that two thirds of cases of CDI were either not picked
up or were misdiagnosed within the hospital due to low clinical awareness of
CDI. ^[2]

The EUCLID study, which involves 20 European countries and approximately 500
hospitals, aims to identify the underlying incidence of CDI in hospitalised
patients with diarrhoea and highlight the extent of under-testing and
under-diagnosis per country. The study was initiated and sponsored by Astellas
Pharma Europe Ltd and endorsed by the European Society of Clinical
Microbiology and Infectious Diseases study group for Clostridium  difficile

"This study represents an important step forward in understanding the true
incidence of CDI and will provide us with much needed information about the
epidemiology of a debilitating disease in Europe," said Dr Ed Kuijper,
Chairman of the ESCMID study group for Clostridium difficile . 

The EUCLID study will be coordinated out of University of Leeds andLeeds
Teaching Hospitals NHS Trust, UK, under Professor Mark Wilcox, with support
from the EUCLID Core Group. The study is funded by Astellas Pharma Europe Ltd.
In each of the participating 20 countries, hospitals will submit samples of
all un-formed faeces received on a specified day to a national coordinating
laboratory where they will be tested for CDI using a standardised protocol.
The sampling will be performed at two different time points in the year to
reflect seasonal variations in CDI which peaks during the winter months. ^[12]
Data will also be collected on any diagnostic CDI test(s) requested within
the hospital for each sample submitted and if so, the test used and the
result. These data, along with reported CDI rates from the previous year, will
be used to calculate the level of under-recognition and under-diagnosis.

A full report and analysis of the findings will be published at the end of the
EUCLID study which is anticipated in mid-2013.

About  Clostridium  Difficile  Infection (CDI)

CDI is a serious illness resulting from infection of the internal lining of
the colon by C.  difficile bacteria. The bacteria produce toxins that cause
inflammation of the colon, diarrhoea and, in some cases, death. ^[13]
Patients typically develop CDI after the use of broad-spectrum antibiotics
that disrupt normal bowel flora, allowing C.  difficile bacteria to
flourish. ^[13] ^, ^[14] The risk of CDI and disease recurrence is
particularly high in patients aged 65 years and older. ^[15] Recurrence of CDI
occurs in up to 25% of patients within 30 days of initial treatment with
current therapies. ^[16] ^, ^[17] ^, ^[18] ESCMID has identified recurrence
as being the most important problem in the treatment of CDI. ^[19] CDI
represents a huge economic burden, ^[5] patients who develop CDI stay in
hospital an extra1-3 weeks ^[5] ^, ^[6] ^, ^[7] at an estimated additional
cost of €7,147 ^[5] compared to those without CDI.
