Abstract
Since the discovery of Clostridium difficile infection (CDI) in the 1970s, there has been an increase in the incidence, severity, and recurrence rate of the disease. We reviewed the recent CDI literature in PubMed published before February 28, 2016 that focused on advances in therapy. Despite a large number of studies describing methods for diagnosing the disease, there is currently no definitive test that identifies this infection with certainty, which complicates therapy. Recommended therapy for CDI includes oral metronidazole for mild cases and oral vancomycin or fidaxomicin for moderate to severe cases, each given for 10 to 14 days. For infection with spore-forming C difficile, this length of treatment may be insufficient to lead to cure; however, continuing antibiotics for longer periods of time may unfavorably alter the microbiome, preventing recovery. Treatment with metronidazole has been associated with an increasing failure rate, and the only clear recommended form of metronidazole for treatment of CDI is the intravenous formulation for patients unable to take oral medications. For vancomycin or fidaxomicin treatment of first CDI recurrences, the drug used in the initial bout can be repeated. For second or future recurrences, vancomycin can be given in pulsed or tapered doses. New modalities of treatment, such as bacteriotherapy and immunotherapy, show promise for the treatment of recurrent CDI.

Abstract
Carbapenem-resistant organisms are increasingly common worldwide, particularly in India and are associated with high mortality rates especially in patients with severe infection such as bacteremia. Existing drugs such as carbapenems and polymyxins have a number of disadvantages, but remain the mainstay of treatment. The tetracycline class of antibiotics was first produced in the 1940s. Minocycline, tetracycline derivative, although licensed for treatment of wide range of infections, has not been considered for treatment of multidrug-resistant organisms until recently and needs further in vivo studies. Tigecycline, a derivative of minocycline, although with certain disadvantages, has been frequently used in the treatment of carbapenem-resistant organisms. In this article, we review the properties of minocycline and tigecycline, the common mechanisms of resistance, and assess their role in the management of carbapenem-resistant organisms.

Abstract
Standard treatment for severe Clostridium difficile infection (CDI) is oral vancomycin with metronidazole. After failure of this standard regimen, treatment becomes challenging. A young woman treated for septic shock developed CDI. Standard treatment failed and she was ineligible for fecal transplant. Addition of tigecycline to her regimen resulted in cure.

Abstract
Clostridium difficile infection (CDI) is known to be associated with prior exposure to many classes of antibiotics. Standard therapy for CDI (i.e., metronidazole and vancomycin) is associated with high recurrence rates. Although tetracycline derivatives such as tetracycline, doxycycline or tigecycline are not the standard therapeutic choices for CDI, they may serve as an alternative or a component of combination therapy. Previous tetracycline or doxycycline usage had been shown to have less association with CDI development. Tigecycline, a broad-spectrum glycylcycline with potency against many gram-positive or gram-negative pathogens, had been successfully used to treat severe or refractory CDI. The in vitro susceptibility of C. difficile clinical isolates to tigecycline in many studies showed low minimal inhibitory concentrations. Tigecycline can suppress in vitro toxin production in both historical and hypervirulent C. difficile strains and reduce spore production in a dose-dependent manner. Tetracycline compounds such as doxycycline, minocycline, and tigecycline possess anti-inflammatory properties that are independent of their antibiotic activity and may contribute to their therapeutic effect for CDI. Although clinical data are limited, doxycycline is less likely to induce CDI, and tigecycline can be considered one of the therapeutic choices for severe or refractory CDI.

Abstract
Fulminant colitis is not a well-defined entity, that constitutes a severe complication. It usually occurs in the course of úlcerative colitis and Clostridium difficile colitis. A multidisciplinary management combining gastroenterologist and surgeons is crucial with intensive medical treatment and early surgery in non-responders. It is important to distinguish if we are facing a flare of IBD or, on the contrary, it is an infectious colitis, due to the fact that although general therapeutic measures to adopt will be the same, they will demand opposed specific measures.

Abstract
Clostridium difficile is mainly a nosocomial pathogen and is a significant cause of antibiotic-associated diarrhea. It is also implicated in the majority of cases of pseudomembranous colitis. Recently, advancements in next generation sequencing technology (NGS) have highlighted the extent of damage to the gut microbiota caused by broad-spectrum antibiotics, often resulting in C. difficile infection (CDI). Currently the treatment of choice for CDI involves the use of metronidazole and vancomycin. However, recurrence and relapse of CDI, even after rounds of metronidazole/vancomycin administration is a problem that must be addressed. The efficacy of alternative antibiotics such as fidaxomicin, rifaximin, nitazoxanide, ramoplanin and tigecycline, as well as faecal microbiota transplantation has been assessed and some have yielded positive outcomes against C. difficile. Some bacteriocins have also shown promising effects against C. difficile in recent years. In light of this, the potential for emerging treatment options and efficacy of anti-C. difficile vaccines are discussed in this review.

Abstract
Introduction Clostridium difficile infection (CDI) is a common cause of nosocomial diarrhea. Metronidazole and vancomycin are the primary treatment options for CDI, but increasing rates of antimicrobial resistance and severe, refractory disease have prompted the need for alternative agents. Tigecycline has previously demonstrated favorable in vitro activity against C. difficile isolates, but clinical data on its use in the treatment of CDI are severely lacking. The objective of this study was to describe our experience using tigecycline in the treatment of severe and severe complicated CDI. Methods This was a retrospective case series of hospitalized patients with severe and severe complicated CDI who were treated with tigecycline. Disease severity assessments were determined according to current practice guidelines. Diagnosis of toxigenic CDI was confirmed by polymerase chain reaction and patients were excluded if they received tigecycline for <48 h. Data were collected by review of the electronic medical record. The primary outcome was clinical cure. Secondary outcomes were sustained response, hospital mortality, and 28-day all-cause mortality. Results A total of 7 cases of severe and complicated CDI were reviewed. Intravenous tigecycline administered as a 100-mg loading dose followed by 50 mg twice daily resulted in clinical cure in 85.7% (n = 6/7) of cases. The majority of patients (n = 4/5) were treated with the novel triple therapy combination of tigecycline, vancomycin, and metronidazole and resulted in clinical cure in 80% (n = 4/5) cases. Sustained response at 28 days was 100% among evaluable cases (n = 5/5). Hospital mortality did not occur in any patients, and 28-day all-cause mortality was 28.6% (n = 2/7). Conclusion Tigecycline appears to be a reasonable addition to the therapeutic regimen in the treatment of severe or complicated CDI, including cases that are refractory to standard therapy. A prospective clinical trial confirming these observational findings is warranted.

Abstract
BACKGROUND Clostridium difficile infection (CDI) is mediated by potent extracellular toxins and is spread largely via bacterial spores. We and others have shown that some antibiotics stimulate C. difficile toxin production in a strain-specific manner; however, the effects of newer anti-C. difficile antibiotics on this process remain to be investigated. METHODS The effects of the protein synthesis inhibitor tigecycline on sporulation and toxin A and toxin B production were compared in historical (strain 9689) and hypervirulent BI/NAP1/027 (strain 5325) isolates of C. difficile in vitro. RESULTS Tigecycline at 1/4× MIC stimulated an increased and earlier toxin A and/or B gene expression in both the historical and the hypervirulent strains, although a commensurate increase in toxin protein production was observed only in the 9689 strain. In fact, in the hypervirulent 5325 strain, toxin production was dramatically suppressed. By comparison, subinhibitory concentrations of vancomycin and metronidazole also stimulated increased protein toxin production by the historical, but not the hypervirulent, strain. In addition, tigecycline dose-dependently reduced viable spore production by both the 9689 and 5325 strains. Vancomycin treatment also suppressed spore formation in both C. difficile strains; however, metronidazole, while reducing spore formation in the 9689 strain, stimulated a near 2 log increase in spore production by the 5325 isolate. CONCLUSIONS In summary, these findings suggest that the treatment of CDI patients with tigecycline could effectively both control disease progression and limit its spread by disrupting sporulation.

Abstract
Clostridium difficile is an anaerobic, Gram-positive pathogen that causes C. difficile infection, which results in significant morbidity and mortality. The incidence of C. difficile infection in developed countries has become increasingly high due to the emergence of newer epidemic strains, a growing elderly population, extensive use of broad spectrum antibiotics, and limited therapies for this diarrheal disease. Because treatment options currently available for C. difficile infection have some drawbacks, including cost, promotion of resistance, and selectivity problems, new agents are urgently needed to address these challenges. This review article focuses on two parts: the first part summarizes current clinical treatment strategies and agents under clinical development for C. difficile infection; the second part reviews newly reported anti-difficile agents that have been evaluated or reevaluated in the last five years and are in the early stages of drug discovery and development. Antibiotics are divided into natural product inspired and synthetic small molecule compounds that may have the potential to be more efficacious than currently approved treatments. This includes potency, selectivity, reduced cytotoxicity, and novel modes of action to prevent resistance.

Abstract
Fulminant colitis is an ill-defined entity that is usually viewed as the most severe form of uncomplicated acute colitis. It usually occurs in the course of ulcerative colitis and infectious colitis, but can also be seen in other forms of colitis. Every patient with clinical criteria for severe or fulminant colitis should be approached in a systematic way, based on two premises - intense medical treatment and early surgery in non-responders.
