class="elsevierStyleSections"><p id="par0005" class="elsevierStylePara elsevierViewall"><span class="elsevierStyleItalic">Clostridium difficile</span> infection (CDI) is the leading cause of hospital-acquired diarrhoea and a growing cause of community-acquired diarrhoea.<a class="elsevierStyleCrossRef" href="#bib0005"><span class="elsevierStyleSup">1</span></a> It has a broad clinical spectrum, and some patients with certain risk factors develop recurrent CDI (rCDI). These risk factors include: advanced age, immunosuppression, chronic kidney disease, concomitant use of antibiotics or of proton pump inhibitors (PPIs), prior episodes of CDI, and presence of hypervirulent strains such as ribotypes 027 or 244.<a class="elsevierStyleCrossRefs" href="#bib0005"><span class="elsevierStyleSup">1,2</span></a></p><p id="par0010" class="elsevierStylePara elsevierViewall">CDI treatment is based on antibiotics such as vancomycin, fidaxomicin or metronidazole; the latter is now considered inferior in terms of efficacy.<a class="elsevierStyleCrossRef" href="#bib0005"><span class="elsevierStyleSup">1</span></a> Faecal microbiota transplantation (FMT) also plays an important role,<a class="elsevierStyleCrossRefs" href="#bib0015"><span class="elsevierStyleSup">3,4</span></a> as it reduces recurrence by 85%–95%. Monoclonal antibodies represent a new approach to preventing recurrence. These include bezlotoxumab, which targets the micro-organism’s toxin B, blocking its action and decreasing intestinal damage.<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">5</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">We report the case of a 62-year-old man with a medical history of: hypertension; Barret’s oesophagus; liver transplantation in 2005 due to liver cirrhosis (caused by hepatitis C virus and alcohol), with recurrence of hepatitis C in the transplant in 2006 (treated with direct-acting antivirals in 2015, which achieved a sustained viral response), evidence of advanced fibrosis in 2016 (12.5 kPa on elastography, METAVIR score F3), but with normal transplanted liver function parameters; osteoporosis; multifactorial chronic kidney disease (stage G3a according to the KDIGO guidelines); and two episodes of intraparenchymal cerebral haemorrhage in 2016 and 2017, with secondary vascular epilepsy, requiring prolonged hospital admission, including a stay in the intensive care unit (ICU). His regular treatment consisted of mycophenolate mofetil (500 mg/8 h), prednisone (5 mg/24 h), levetiracetam, pantoprazole and oral calcium.</p><p id="par0020" class="elsevierStylePara elsevierViewall">In May 2017, in the last months of admission for cerebral haemorrhage, he had an initial episode of CDI that did not meet criteria to be considered severe. He was treated with a regular regimen of oral vancomycin (125 mg/6 h for 10 days), and his signs and symptoms resolved. Two weeks later, he had his first CDI recurrence, which was again treated with vancomycin, with a down-titration regimen at discharge. In October 2017, his second recurrence occurred; he was given fidaxomicin 200 mg/12 h for 10 days, responding favourably. Three months later, the third recurrence occurred and, after vancomycin treatment, underwent a first FMT. Despite this procedure, he had further recurrences in February and April 2018, and a decision was made to perform a second FMT. In the months that followed, the patient was admitted for new episodes, which were treated with vancomycin. With his eighth recurrence in March 2019, it was decided to administer bezlotoxumab during the course of treatment with vancomycin. It was administered in a single intravenous infusion for 60 min, at a dose of 10 mg/kg, with no need to make adjustments based on kidney or liver function. No short- or middle-term side effects were documented and, after 12 months, no new episodes of rCDI have occurred. It should be noted that the initial episode and all recurrences were mild, not meeting criteria for severity, and accompanied by diarrhoea and mild worsening of kidney function on every occasion.</p><p id="par0025" class="elsevierStylePara elsevierViewall">Several risk factors for recurrence of CDI converged in our patient: advanced age, immunosuppression, chronic kidney disease, PPI use and numerous recurrent episodes with exhaustion of available treatment options, including two FMTs. Treatment with bezlotoxumab is indicated in patients 18 years of age and older receiving treatment for CDI and at high risk of recurrence<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">5</span></a>; in our case, these criteria were fulfilled. Bezlotoxumab is the first drug authorised to prevent rCDI, and the results of the clinical trials conducted<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">5</span></a> confirm that it reduces recurrence rates. However, there is still no experience with repeat administration of the drug and there are still no data comparing it to other drugs.</p><p id="par0030" class="elsevierStylePara elsevierViewall">Solid organ transplant recipients are under-represented in the majority of clinical trials and registry studies.<a class="elsevierStyleCrossRef" href="#bib0015"><span class="elsevierStyleSup">3</span></a> They also have higher rates of morbidity and mortality due to their clinical condition, their treatments and factors such as more frequent hospitalisations and greater use of antibiotics.<a class="elsevierStyleCrossRef" href="#bib0020"><span class="elsevierStyleSup">4</span></a> The choice of a specific treatment should be tailored to each patient’s condition and risk of recurrence.</p></span>" "pdfFichero" => "main.pdf" "tienePdf" => true "NotaPie" => array:1 [ 0 => array:2 [ "etiqueta" => "☆" "nota" => "<p class="elsevierStyleNotepara" id="npar0005">Please cite this article as: Hernández M, Saura N, García S, Velamazán R, Abad D, Hijos G, et al.
