Microbiota is Related With Increasing Infection Rates After Splenectomy

Status Recruiting

Clinical Trial Summary

Studies has shown an increasingly infection rate after splenectomy, and there is a potential correlation between microbiota and immune system. investigators suppose that increasingly infection can be associated with the alteration composition of the gut microbiota after splenectomy. It's investigators' aim to discover if any difference of gut microbiota is exist in patients who suffer from traumatic splenectomy compared with normal people, ultimately aim toreduce and mitigation infection rate through controlling gut microbiota.

Clinical Trial Description

The spleen is crucial in regulating immune homoeostasis through its ability to link innate and adaptive immunity and to protect against infections. Asplenia refers to the absence of the spleen, a disorder that is rarely congenital and is more frequently as a result of surgery. Splenic hypofunction, as a result of asplenia can lead a series of changes in body systems. Recent study has show an increasingly infection rate after splenectomy including abdominal infection, pulmonary infection and cranial cavity infection.

The gastrointestinal tract plays host to a diverse and metabolically complex community of microorganisms. Recent literature suggests that organisms in the gastrointestinal tract, referred to collectively as gut microbiota, play an indispensable role in the maintenance of host's homeostasis. Study has proved a potential correlation between microbiota and immune system. Lymphocyte, in either peripheral circulation or mesenteric lymph node, altered can lead to an composition change in microbiota.

Investigators suppose that this phenomenon can be associated with the alteration of the resident commensal microenvironment after splenectomy compared to commensal communities. It's investigators' aim to discover if any difference of gut microbiota is exist in patients who suffer from traumatic splenectomy compared with normal people, ultimately aim toreduce and mitigation infection rate through controlling gut microbiota. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
