Thanks for your query and specific information and understanding cause of failed treatment can be either of the following:-The ATT is ineffective, so may need a second line of ATT anti tuberculosis treatment with of lox and other medicines under the guidance of the Specialist.-Needs exploration, removal of the lymph nodes and subject to histopathology as there is possibility of another diagnosis like Lymphoma.-Supportive treatment of proteins and iron, -Get all relevant blood tests particularly the Liver function tests.
