Fecal microbiota(Mikrobiomik Healthcare)

Patients with microbiota alterations developed after being exposed to antibiotics are especially susceptible to Clostridioides difficile infections (CDI). The incidence and severity of CDI has increased in recent years and CDI recurrences (r-CDI) due to the appearance of new episodes in patients with a previous cured CDI, represent a serious and complex clinical issue. Although antibiotics are the recommended therapy for the first episode of CDI, treatment with oral vancomycin and/or metronidazole often results in significant treatment failure. In addition, the treatment of r-CDI is not adequately standardized, and although the most widely used treatment is the administration of fidaxomicin and bezlotoxumab, its efficacy in patients who already have r-CDI is not proven. In the late years, Fecal Microbiota Transfer (FMT) has emerged as the preferred non-pharmacological treatment to manage CDI with multiple recurrences and recent clinical trials have evaluated its potential efficacy and safety in the treatment of patients with primary CD infection.
The objective of this study is to assess the efficacy and safety of the MBK-01 medication, consisting of heterologous lyophilized fecal microbiota capsules coming from healthy donors in comparison to the treatment with Fidaxomicin, in 66 patients with primary or r-CDI.

Infections caused by carbapenemase-producing Enterobacteriaceae are frequent and often associated with high rates of mortality. Colonized patients are at increased risk of infection for these microorganisms. Moreover, they can act as a reservoir facilitating the transmission to other patients. To date, decolonization strategies with antibiotics have not obtained convincing results. For that reason our main objective is to investigate the efficacy of fecal microbiota transplantation (FMT) for selective intestinal decolonization of patients colonized by KPC-producing Klebsiella pneumoniae (Kp-KPC) at 30 days after FMT. Our hypothesis is that FMT is effective and safe for selective intestinal decolonization in patients colonized by Kp-KPC. The design of the study is a randomized, superiority, double blind controlled with placebo clinical trial.
The main variable is the percentage of patients with intestinal decolonization at 30 days after FMT in intention to treat population (all randomized patients). Decolonization will be considered as the abscence of isolation of Kp-KPC in culture from rectal swab together with the abscence of detection of carbapenemase by mean of polymerase chain reaction.
Secondary objectives are:
* To evaluate the safety of FMT.
* To determine if FMT is associated with decrease in the amount of bacteria at 7 days after FMT and 30 days after FMT.
* To evaluate if FMT is associated with persistent intestinal decolonization at 3 months after intervention.
* To study if FMT is associated with decrease in the incidence of Kp-KPC infections at 3 months after intervention.
* To evaluate if FMT is associated with decrease in mortality due to Kp-KPC infections at 3 months after intervention.
