Hello, this is tough to handle like these situations when you are the relative of a suffering person. When I check your clinical history, Diabetic Fever and infection in kidney. Renal failure on dialysis and recent dialysis Rashes peels of skin vomiting diarrhoea Most striking point at present is, rashes and peel off skin, these things common with drug reaction.doctor should visualize exactly the nature Of skin rashes, it may stevene jhonson syndrome due to drugs. Diabetic are prone to develop sepsis (spread of bacteria throughout the blood) especially from kidney source of infection.(may be pyelonephritis). Sepsis is very morbid state we have to treat the patient in icu setup with higher antibiotics. What those antibiotics are good for that patient. If patient renal failure because of sepsis than chance of recovery from dialysis is high. If it s diabetic neuropathy with chronic renal failure(ckd) we have to continue the dialysis. At present the care is correct, check once with your consultant if these reactions because of drug.
