[|AI|]  Hello, It is challenging to come to diagnosis with a limited history provided in the query. However, the use of long term antibiotic therapy is called for patients who suffer with immunodeficiency. The antibiotics prevent the risk of acquiring recurrent severe infections in such patients. As you have mentioned your grand child is five months old; it is likely that she is suffering from some form of rare congenital immunodeficiency. In this condition the normal infection-fighting system of the body does not function fully, making the person prone to severe infections. Apart from antibiotics other forms of treatment available for such patients includes antibody infusion, and stem cell transplantation. In addition, kidneys are usually normal as the immune cells are usually a component of blood.  Hope I have answered your query. Let me know if I can assist you further.
