Effect of Probiotics on Immunosuppressive-drug-associated Diarrhea Among Renal Transplant Recipients

The goal of this pilot project is to 1) examine whether oral administration of probiotics are helpful in reducing immunosuppressive drugs-associated diarrhea and adhering to the required dose of immunosuppressive drugs and 2) determine how this treatment works by examining fecal microbiome and immunological markers among living and deceased donor renal transplant recipients. The main questions it aims to answer are: 1. Does low dose probiotics effective in reducing immunosuppressive drugs-associated diarrhea? 2. Does probiotics effective in reducing inflammation? 3. Is there any connection between fecal microbiome and immunological markers? Participants will receive one probiotics capsule or placebo capsule daily for 6 months from the onset of diarrhea post-surgically. Researchers will compare the data obtained through probiotics group and placebo group to answer the above mentioned research questions.
