Fecal Transplants for Psoriatic Arthritis?


#1

Because there appears to be a strong association between microbiome and psoriatic arthritis, I looked to see if there has been any research on fecal transplants and psoriatic arthritis. This is what I’ve found so far:

Recent years have seen growing recognition of the complexity of the role of the microbiota in shaping the immune system and its potential effects for health and disease. In particular, the gut bacteria composition has been associated with the pathogenesis of autoimmune and inflammatory diseases. Intriguingly, presence of intestinal inflammation in psoriatic arthritis (PsA) patients has been documented in several studies. Also, in genetically predisposed patients reactive arthritis, which share some of the clinical manifestations of PsA, can be triggered by certain types of bacterial gut infections. Furthermore, a recent study has reported that several intestinal bacteria including Akkermansia and Ruminoccocus, which are known to play an important role in maintaining gut homeostasis, were practically absent in PsA patients. Mechanisms through which the microbiota may be involved in the pathogenesis of PsA include an abnormal activation of the gut-associated lymphoid tissue (GALT) and/or an altered mucosal permeability thus compromising the capacity of the intestine to provide adequate containment of luminal microorganisms and molecules.

By conducting a double-blinded, randomized, placebo-controlled trial of a non-related donor fecal microbiota transplantation (FMT) infused into the small intestine, this study will reveal whether FMT is more effective than an identically appearing placebo (saline) in reducing disease activity in psoriatic arthritis patients presenting with a minimum of three swollen joints despite at least three months of s.c. methotrexate treatment (maximal tolerable dosis ≥ 15 mg/week). All patients will throughout the study continue their individual treatment with weekly s.c. methotrexate.

and:

Core tip: Fecal microbiota transplantation (FMT) achieved a successful cure rate in recurrent Clostridium difficile infection. Although there is a deficiency of randomized controlled trials, the present review reveals that FMT could be a promising rescue therapy in extra-intestinal disorders associated with gut microbiota, including metabolic diseases, neuropsychiatric disorders, autoimmune diseases, allergic disorders, and tumors.

I would not hesitate to try it.
