Pseudomembranous colitis as a complication in Covid-19.

OBJECTIVE: Aim: To improve the results of treatment of patients with pseudomembranous colitis against the background of coronavirus infection. PATIENTS AND METHODS: Materials and Methods: The study presents the results of a retrospective analysis of 96 patients with pseudomembranous colitis, who were treated in the infectious Covid department at the base of the Uzhhorod City Clinical Hospital since 2020 to 2022. The average age of patients was 55.2 years, there were 38 (39.5%) men and 58 (60.5%) women. Diagnosis of complications - pseudomembranous colitis (PMC) - was based on clinical data, ultrasound and CT of the abdominal organs, fibrocolonoscopy, laparoscopy. RESULTS: Results: The frequency of PMC from the total number of patients who were in hospital treatment (8205 patients) due to COVID-19 was 1.17%, and this indicator was 0.62% in 2020, and 2.28% in 2021. Indications for operative treatment were: colon perforation - 9.4% of patients; peritonitis (diffuse, widespread) without obvious perforation of the colon wall - 85.5% of patients; mesenteric thrombosis - 4.1% of patients. In the case of perforation of the colon, resection of the colon was performed with the formation of a proximal colostomy and ileostomy. In case of mesenteric thrombosis, resection of the affected part of the small intestine was performed. In case of peritonitis without clear intraoperative detection of perforation of the colon wall, intraoperative lavage was performed. CONCLUSION: Conclusions: 1) The frequency of detection of PMC in patients with COVID-19 in 2020 was 0.62%, and in 2021 - 2.28%. 2) The sensitivity of CT in the diagnosis of surgical complications of PMC was 72%, and the specificity was 58%. 3) Conservative treatment was effective in patients with PMC in 88.8% of cases, 21.2% had complications that required emergency surgical interventions. 4) The total mortality in patients with PMC was 11.36%, although this indicator was significantly higher in the event of surgical complications and operative treatment (22.4%).

Pseudomembranous colitis and Parabacteroides distasonis bacteraemia: a rare clinical presentation.

We present the case of a male with end-stage diabetic nephropathy on haemodialysis who initially presented with acute-on-chronic digital ulceration. While awaiting vascular intervention, he became septic with abdominal pain and diarrhoea. Flexible sigmoidoscopy confirmed pseudomembranous colitis secondary to Clostridium difficile. Blood cultures grew Parabacteroides distasonis, a Gram-negative gut anaerobe. Enterobacter cloacae, another Gram-negative anaerobic gut bacilli, was grown in colonic cultures and swabs of the digital ulcers. We hypothesise that the pseudomembranous colitis increased gut translocation and thus led to the systemic spread of both gut anaerobes. This is the first reported case of Parabacteroides distasonis bacteraemia in the context of Clostridium difficile infection. Our patient recovered with antibiotics and went on to have vascular intervention for his digital ulceration.

Investigating the impact of antibiotic-induced dysbiosis on protection from Clostridium difficile colitis by mouse colonic innate lymphoid cells.

Innate lymphoid cells (ILCs) play a critical role in maintaining intestinal health in homeostatic and diseased conditions. During Clostridium difficile infection (CDI), IL-33 activates ILC2 to protect from colonic damage and mortality. The function of IL-33 and ILC is tightly regulated by the intestinal microbiota. We set out to determine the impact of antibiotic-induced disruption of the microbiome on ILC function. Our goal was to understand antibiotic-induced changes in ILC function on susceptibility to C. difficile colitis in a mouse model. We utilized high-throughput single-cell RNAseq to investigate the phenotypic features of colonic ILC at baseline, after antibiotic administration with or without IL-33 treatment. We identified a heterogeneous landscape of colonic ILCs with gene signatures of inflammatory, anti-inflammatory, migratory, progenitor, plastic, and antigen-presenting ILCs. Antibiotic treatment decreased ILC2 while coordinately increasing ILC1 and ILC3 phenotypes. Notably, Ifng+, Ccl5+, and Il23r+ ILC increased after antibiotics. IL-33 treatment counteracted the antibiotic effect by downregulating ILC1 and ILC3 and activating ILC2. In addition, IL-33 treatment markedly induced the expression of type 2 genes, including Areg and Il5. Finally, we identified amphiregulin, produced by ILC2, as protective during C. difficile infection. Together, our data expand our understanding of how antibiotics induce susceptibility to C. difficile colitis through their impact on ILC subsets and function.IMPORTANCEClostridium difficile infection (CDI) accounts for around 500,000 symptomatic cases and over 20,000 deaths annually in the United States alone. A major risk factor of CDI is antibiotic-induced dysbiosis of the gut. Microbiota-regulated IL-33 and innate lymphoid cells (ILCs) are important in determining the outcomes of C. difficile infection. Understanding how antibiotic and IL-33 treatment alter the phenotype of colon ILCs is important to identify potential therapeutics. Here, we performed single-cell RNAseq of mouse colon ILCs collected at baseline, after antibiotic treatment, and after IL-33 treatment. We identified heterogeneous subpopulations of all three ILC subtypes in the mouse colon. Our analysis revealed several potential pathways of antibiotic-mediated increased susceptibility to intestinal infection. Our discovery that Areg is abundantly expressed by ILCs, and the protection of mice from CDI by amphiregulin treatment, suggests that the amphiregulin-epidermal growth factor receptor pathway is a potential therapeutic target for treating intestinal colitis.

An Updated View on the Cellular Uptake and Mode-of-Action of Clostridioides difficile Toxins.

Research on the human gut pathogen Clostridioides (C.) difficile and its toxins continues to attract much attention as a consequence of the threat to human health posed by hypervirulent strains. Toxin A (TcdA) and Toxin B (TcdB) are the two major virulence determinants of C. difficile. Both are single-chain proteins with a similar multidomain architecture. Certain hypervirulent C. difficile strains also produce a third toxin, namely binary toxin CDT (C. difficile transferase). C. difficile toxins are the causative agents of C. difficile-associated diseases (CDADs), such as antibiotics-associated diarrhea and pseudomembranous colitis. For that reason, considerable efforts have been expended to unravel their molecular mode-of-action and the cellular mechanisms responsible for their uptake. Many of these studies have been conducted in European laboratories. Here, we provide an update on our previous review (Papatheodorou et al. Adv Exp Med Biol, 2018) on important advances in C. difficile toxins research.

The microbial metabolite urolithin A reduces Clostridioides difficile toxin expression and toxin-induced epithelial damage.

Clostridioides difficile is a Gram-positive, anaerobic, spore-forming bacterium responsible for antibiotic-associated pseudomembranous colitis. Clostridioides difficile infection (CDI) symptoms can range from diarrhea to life-threatening colon damage. Toxins produced by C. difficile (TcdA and TcdB) cause intestinal epithelial injury and lead to severe gut barrier dysfunction, stem cell damage, and impaired regeneration of the gut epithelium. Current treatment options for intestinal repair are limited. In this study, we demonstrate that treatment with the microbial metabolite urolithin A (UroA) attenuates CDI-induced adverse effects on the colon epithelium in a preclinical model of CDI-induced colitis. Moreover, our analysis suggests that UroA treatment protects against C. difficile-induced inflammation, disruption of gut barrier integrity, and intestinal tight junction proteins in the colon of CDI mice. Importantly, UroA treatment significantly reduced the expression and release of toxins from C. difficile without inducing bacterial cell death. These results indicate the direct regulatory effects of UroA on bacterial gene regulation. Overall, our findings reveal a novel aspect of UroA activity, as it appears to act at both the bacterial and host levels to protect against CDI-induced colitis pathogenesis. This research sheds light on a promising avenue for the development of novel treatments for C. difficile infection.IMPORTANCETherapy for Clostridioides difficile infections includes the use of antibiotics, immunosuppressors, and fecal microbiota transplantation. However, these treatments have several drawbacks, including the loss of colonization resistance, the promotion of autoimmune disorders, and the potential for unknown pathogens in donor samples. To date, the potential benefits of microbial metabolites in CDI-induced colitis have not been fully investigated. Here, we report for the first time that the microbial metabolite urolithin A has the potential to block toxin production from C. difficile and enhance gut barrier function to mitigate CDI-induced colitis.

Estudio de casos-controles de la infección por Clostridioides difficile en un área sanitaria rural / Case-control study of Clostridioides difficile in a rural health care area

Objetivo: Determinar los factores de riesgo y factores pronósticos de la infección por Clostridioides difficile (ICD). Pacientes y métodos: Estudio prospectivo de casos-controles (61 casos y 64 controles) de 2 años o más con diarrea, atendidos en un área sanitaria manchega durante 14 meses. El diagnóstico se realizó mediante inmunocromatografía (glutamato deshidrogenasa y toxina A/B), realizando amplificación isotérmica en los casos discordantes. Se recogieron variables demográficas, comorbilidades, tipo de adquisición, administración previa de antibióticos, antiácidos e inmunosupresores y evolución. Los datos se analizaron mediante la prueba de χ2 y el efecto de los factores de riesgo y pronósticos se cuantificó mediante odds ratio con intervalos de confianza del 95%. Resultados: Como factores de riesgo independientes de ICD encontramos el ingreso hospitalario las 4 semanas previas a la infección, la hipoalbuminemia y la administración previa de antibióticos. Presentar estos 3 factores supuso un riesgo casi 3 veces mayor de infectarse. En el grupo de adquisición nosocomial se encontró mayor número de ingresos hospitalarios las 4-12 semanas previas a la ICD y, aunque hubo mayor tendencia a las recurrencias y al pronóstico desfavorable entre los casos intrahospitalarios, estas diferencias no fueron significativas. Identificamos como factores de pronóstico desfavorable la fiebre y el ingreso hospitalario las 4 semanas previas a la infección. Conclusiones:Los factores de riesgo independientes de ICD fueron: ingreso hospitalario las 4 semanas previas a la infección, hipoalbuminemia y administración previa de antibióticos. La fiebre y la hospitalización las 4 semanas anteriores se identificaron además como factores pronósticos de evolución desfavorable.(AU)

Objective: To determine the risk and prognostic factors for Clostridioides difficile infection (CDI). Patients and methods: Prospective, case-control study with 61 cases and 64 controls, aged ≥2 years with diarrhoea, carried out in Castilla-La Mancha Health Care Area for 14 months. The diagnosis was made by immunochromatography technics (glutamate dehydrogenase and toxin A/B), confirming discordant cases by isothermal amplification. Demographic variables, comorbidities, type of acquisition, previous administration of antibiotics, antacids and immunosuppressants, and evolution were collected. The data were analysed using the chi-square test and the effect of risk and prognostic factors was quantified using an odds ratio with 95% confidence intervals. Results: Hospital admission 4 weeks prior to infection, hypoalbuminemia, and previous administration of antibiotics were identified as independent risk factors for CDI. Presenting these 3 factors constitutes nearly 3-fold increase in the risk of becoming infected. A greater number of hospital admissions in the 4-12 weeks prior to CDI were found in the group of nosocomial acquisition. Although there was a greater tendency to recurrence and an unfavourable prognosis among nosocomial cases, these differences were not significant. We found that fever and hospital admission in the 4 weeks prior to infection were unfavourable prognostic factors of CDI. Conclusions: The independent risk factors for CDI were: Hospital admission in the 4 weeks prior to infection, hypoalbuminemia, and previous administration of antibiotics. Fever and hospitalisation in the previous 4 weeks were also identified as prognostic factors of unfavourable evolution.(AU)

Clostridioides difficile infection following procalcitonin-guided antibiotic therapy for COVID-19

@#We present a case of a 50-year-old man with chronic kidney disease (CKD) presenting with acute diarrhea and fever. He was admitted a month prior for COVID-19, where he received antibiotics for radiographic findings of pneumonia and elevated procalcitonin. In the emergency department, his stool sample tested positive for Clostridioides difficile antigen and toxin. He was given oral vancomycin and intravenous metronidazole for fulminant C. difficile infection and was discharged with resolution of symptoms. This case documents a potential risk associated with routine antibiotic use during the pandemic and the pitfalls in interpreting procalcitonin, especially in patients with COVID-19 and CKD.

Analysis of biofilm production and expression of adhesion structures of circulating Clostridioides difficile strains from Mexico / Análisis de la producción de biopelícula y expresión de estructuras de adhesión de cepas circulantes de Clostridioides difficile en México

Introduction: Clostridioides difficile biofilms are believed to protect the pathogen from antibiotics, in addition to potentially contributing to recurrent infections. Methodology: Biofilm production of 102 C. difficile isolates was determined using the crystal violet staining technique, and detachment assays were performed. The expression levels of cwp84 and slpA genes were evaluated by real-time PCR on selected isolates. Results: More than 70% of isolates (75/102) were strong biofilm producers, and the highest detachment of biofilm was achieved with the proteinase K treatment (>90%). The overall mean expression of cwp84 was higher in RT027 than in RT001 (p=0.003); among strong biofilm-producing strains, the slpA expression was lower in RT027 than in RT001 (p<0.000). Conclusions: Proteins seem to have an important role in the biofilm's initial adherence and maturation. slpA and cwp84 are differentially expressed by C. difficile ribotype and biofilm production level.(AU)

Introducción: Se cree que las biopelículas de Clostridioides difficile (C. difficile) protegen al patógeno de los antibióticos, además de contribuir potencialmente a las infecciones recurrentes. Metodología: Se determinó la producción de biopelículas de 102 aislados de C. difficile, mediante la técnica de tinción con violeta cristal y se realizaron ensayos de desprendimiento. Los niveles de expresión de los genes cwp84 y slpA se evaluaron mediante PCR en tiempo real en aislados seleccionados. Resultados: Más del 70% de los aislados (75/102) fueron fuertes productores de biopelículas y el mayor desprendimiento de biopelícula se logró con el tratamiento con proteinasa K (> 90%). La expresión media global de cwp84 fue mayor en RT027 que en RT001 (p = 0,003); entre las cepas productoras fuertes de biopelícula, la expresión de slpA fue menor en RT027 que en RT001 (p < 0,000). Conclusiones: Las proteínas parecen tener un papel importante en la adhesión y maduración inicial de las biopelículas; slpA y cwp84 se expresan de forma diferente según el ribotipo de C. difficile y el nivel de producción de biopelículas.(AU)

Clostridium perfringens α and ß recombinant toxoids in equine immunization / Toxóides recombinantes α e ß de Clostridium perfringens na imunização de equinos

Clostridium perfringens is considered one of the main causative agents of superacute enterocolitis, usually fatal in the equine species, due to the action of the ß toxin, and is responsible for causing severe myonecrosis, by the action of the α toxin. The great importance of this agent in the equine economy is due to high mortality and lack of vaccines, which are the main form of prevention, which guarantee the immunization of this animal species. The aim of this study was to evaluate three different concentrations (100, 200 and 400µg) of C. perfringens α and ß recombinant toxoids in equine immunization and to compare with a group vaccinated with a commercial toxoid. The commercial vaccine was not able to stimulate an immune response and the recombinant vaccine was able to induce satisfactory humoral immune response in vaccinated horses, proving to be an alternative prophylactic for C. perfringens infection.(AU)

Clostridium perfringens é considerado um dos principais agentes causadores de enterocolites superagudas, geralmente fatais na espécie equina, devido à ação da toxina ß, além de ser responsável por causar quadros graves de mionecrose, pela ação da toxina α. A grande importância desses agentes na equinocultura, deve-se a elevada mortalidade e a inexistência de vacinas, principal forma de prevenção, que garantam a imunização dessa espécie animal. O objetivo deste trabalho foi avaliar três diferentes concentrações (100, 200 e 400µg) dos toxóides recombinantes α e ß de C. perfringens na imunização de equinos, bem como comparar com um grupo vacinado com um toxóide comercial. A vacina comercial não se mostrou capaz de estimular uma resposta imune e a vacina recombinante foi capaz de induzir resposta imune humoral satisfatória em equinos vacinados, provando ser uma alternativa profilática para infecção por C. Perfringens.(AU)

Transplantes de microbiota fecal para tratamento da colite pseudomembranosa (1958-2013): prioridade de descoberta e estilos de pensamento na literatura acadêmica / Fecal microbiota transplants in the treatment of pseudomembranous colitis (1958-2013): priority of discovery and thought styles in the academic literature

Resumo Em 1958, Eiseman e colaboradores publicaram o primeiro artigo científico relatando o uso de transplante de microbiota fecal para tratar casos graves de colite pseudomembranosa. A relevância desse trabalho inovador só foi reconhecida em 1990. A literatura acadêmica sobre o tema caracteriza-se por sucessivas reconstruções. Sugerimos que tais reconstruções foram orientadas por questões de atribuição de prioridade de descoberta científica nos termos propostos por Merton. A retomada do uso de transplantes de microbiota fecal é interpretada como processo de gênese de um fato científico, conforme Fleck: ocorre a mudança de um estilo de pensamento baseado no uso de antibióticos no tratamento de doenças infecciosas para outro que considera as relações ecológicas entre hospedeiros, vetores e agentes etiológicos de doenças.

Abstract In 1958, Eiseman and contributors published the first scientific paper reporting the use of fecal microbiota transplant for treating pseudomembranous colitis. The relevance of this innovative paper was only acknowledged in 1990. The academic literature on the theme is characterized by a narrative that has undergone successive revisions. We suggest that such revisions were based on claims of priority of scientific discoveries, as described by Merton. The revival of fecal microbiota transplants is interpreted as a process of genesis of a scientific fact, as defined by Fleck: there is a switch from a thought style based on the use of antibiotics to treat infectious diseases to another that accepts the ecological relations between hosts, vectors and parasites.

Diarrea clostridial. Un patógeno nosocomial a tener en cuenta / Clostridial diarrhea. A nosocomial pathogen to take into account

La diarrea clostridial es una enfermedad aguda con compromiso colónico que puede poner en riesgo la vida de un paciente. Su agente etiológico es el Clostridium difficile y se ha asociado al uso indiscriminado y por largo plazo de antibióticos de amplio espectro. Su cuadro clínico es variable, puede ir desde un cuadro de diarrea hasta la perforación colónica, que puede determinar la realización de una colectomía de urgencia o incluso provocar la muerte del enfermo. El diagnóstico de certeza se realiza mediante la detección de la toxina clostridial en materia fecal, por técnicas de inmunoensayo enzimático. La terapéutica se realiza con metronidazol o vancomicina por vía oral. El tratamiento quirúrgico está indicado ante la presencia de megacolon tóxico o perforación intestinal, y en aquellos pacientes con toxicidad sistémica con fracaso de la terapéutica médica. (AU)

Clostridial diarrhea is an acute disease with colonic involvement that can be life-threatening for a patient. Its etiologic agent is the Clostridium difficile and it has been associated with the indiscriminate and long-term use of broad-spectrum antibiotics. Its clinical picture varies from a picture of diarrhea to colonic perforation that can determine the performance of an emergency colectomy or even the death of the patient. The certainty diagnosis is carried out by detecting clostridial toxin in fecal matter by enzyme immunoassay techniques. The therapy is carried out with metronidazole or vancomycin orally. Surgical treatment is indicated in the presence of toxic mega colon, intestinal perforation or in those patients with systemic toxicity with failure of medical therapy. (AU)

Doctor, my patient has CDI and should continue to receive antibiotics. The (unresolved) risk of recurrent CDI

Recurrence rate ranges from 12% to 40% of all cases of Clostridium difficile infection (CDI) and proposes an exceptional clinical challenge. Conventionally, treatment options of CDI have been limited to regimes of established antibiotics (eg, pulsed/tapered vancomycin) or "improvised" alternative antibiotics (eg. teicoplanin, tigecycline, nitazoxanide or rifaximin) occasionally even in combination, but faecal microbiota transplantation is emerging as a useful and quite safe alternative. In recent years, promising new strategies have emerged for effective prevention of recurrent CDI (rCDI) including new an-timicrobials (eg, fidaxomicin) and monoclonal antibodies (eg, bezlotoxumab). Despite promising progress in this area, difficulties remain for making the best use of these resources due to uncertainty over patient selection. This positioning review describes the current epidemiology of rCDI, its clinical impact and risk factors, some of the measures used for treating and preventing rCDI, and some of the emerging treatment options. It then describes some of the barriers that need to be overcome

Incidence and characterization of Clostridium difficile in a secondary care hospital in Spain

Introduction: Clostridium difficile (C. difficile) is a major nosocomial infectious agent in hospitals. Previous studies have addressed the high proportion of infection episodes that are overlooked in health care facilities. Objective: the main aim of this study was to characterize C. difficile clinical cases that occurred in a secondary care hospital during a five-month period. Material and methods: for this purpose, a total of 137 stool samples from the same number of patients with diarrhea were analyzed for the presence of C. difficile by culture techniques. An enzyme immunoassay (EIA) test for the detection of C. difficile and its toxins was also used in 50 cases (36.5%) for diagnostic purposes. Results: a total of 14 (10.2%) C. difficile isolates were obtained, of which nine (64.3%) were toxigenic. A mean incidence of 3.2 episodes of C. difficile infections (CDI) per 10,000 patients-days was estimated for the study period. Around 56% of the CDI cases were determined as hospital-acquired, whereas 44% originated in the community. Among these, only two episodes (22.2%) were detected in the hospital by the EIA test, which indicated that the hospital CDI detection protocol needed to be revised. One unusual C. difficile isolate was negative for all toxin genes examined and also for the non-toxigenic strain assay, which highlights the need to perform genome sequencing to study its pathogenicity locus insertion site organization. A stable metronidazole-resistant C. difficile strain and three strains showing multidrug resistance were detected in this study, suggesting that C. difficile antimicrobial susceptibility surveillance programs should be established in this health-care facility

Colitis pseudomembranosa: a propósito de un caso / Pseudomembranosa colitis: apropos of a case

Fundamento: la colitis pseudomembranosa es una enfermedad causada por el clostridium difficile en los últimos tiempos ha llamado la atención de la comunidad médica, por aumento en la incidencia en las instituciones de salud, así como, en la comunidad, motivado por el consumo frecuente y a veces no ordenado de antimicrobianos. Objetivo:describir un caso de un paciente con diagnóstico postmorten de colitis pseudomembranosa. Caso clínico: paciente masculino de 71 años con antecedentes de enfermedad pulmonar obstructiva crónica y válvula protésica mitral, con esquemas de tratamientos antimicrobianos profilácticos cada mes para evitar infecciones respiratorias, el cual ingresó por presentar deposiciones diarreicas de escasa cantidad pero frecuentes con abundante sangre y moco acompañado de fiebre y dolor abdominal, con una evolución intrahospitalaria tórpida hasta su fallecimiento, el diagnóstico en la necropsia realizada arrojó una colitis pseudomembranosa. Conclusiones: la colitis pseudomembranosa producida por el clostridium difficile es una enfermedad que hay que tener presente en los diagnósticos de paciente hospitalizados los cuales se encuentran con tratamiento antimicrobianos o que procedan de la comunidad donde se les prescribió con este tipo de fármacos(AU)

Background: pseudomembranous colitis is a disease caused by Clostridium difficile in recent times has attracted the attention of the medical community, due to an increase in the incidence in health institutions, as well as in the community, motivated by the more frequent use and sometimes not ordered antimicrobials.Objective: to describe a case of a patient with a postmortem diagnosis of pseudomembranous colitis. Clinical case: a 71-year-old male patient with a history of chronic obstructive pulmonary disease and mitral prosthetic valve to receive from several months prophylactic antimicrobial cycles every month to avoid respiratory infections, who is admitted due to scarce diarrheic stools, but frequent with abundant blood and mucus accompanied by fever and abdominal pain, with an intra-hospital torpid evolution until his death, performing the diagnosis of pseudomembranous colitis in the necropsy study. Conclusions: the pseudomembranous colitis produced by Clostridium difficile is a disease that has to be kept in mind in the diagnoses of hospitalized patients who are under antimicrobial treatment or who come from the community where they were prescribed with this type of drugs(AU)

A comprehensive approach for the patient with Clostridium difficile infection / Valoración integral del paciente con infección por Clostridium difficile

During the last decade there have been many changes and advances in the research on Clostridium difficile infection (CDI). We have improved diagnostic and therapeutic tools and, at the same time, we have learned that the CDI implies, especially in the most vulnerable patients, an important morbidity. CDI has traditionally been undervalued and it is widely dispersed in hospitals. Surely, there is inertness in its management and there are also broad areas of improvement. If we add to this the high cost of the new drugs and the practical difficulties to implement the faecal microbiota transplant, we realize that we may not be taking full advantage of all the opportunities to improve patient's outcomes. The implementation of policies that favour the supervision of all CDI cases by an expert in infectious diseases will contribute to a better global management of this important disease

Durante la última década ha habido muchos cambios y avances en la investigación sobre la infección por Clostridium difficile (ICD). Han mejorado las herramientas diagnósticas y el tratamiento de la enfermedad al mismo tiempo que hemos aprendido que la ICD implica, especialmente en los pacientes más vulnerables, una importante morbilidad. La ICD ha sido tradicionalmente infravalorada y su atención médica está muy dispersa en los hospitales. Seguramente, hay una gran inercia en el manejo de esta enfermedad y, por ello, amplias áreas de mejora. Si a lo anterior sumamos el alto coste de los nuevos medicamentos y las dificultades prácticas para implementar el trasplante de microbiota fecal, es fácil concluir que no aprovechemos al máximo todas las oportunidades para mejorar los resultados clínicos que padecen ICD. La implementación de políticas que favorezcan la supervisión de todos los casos de ICD por parte de un experto en enfermedades infecciosas contribuirá a un mejor manejo global de esta importante enfermedad
