Father has sudden delirium with cancer. Kidney and liver functions not perfect but ok.  Has been fighting bladder cancer, has prostate cancer cells and now liver tumor.  Was hospitalized with cellulitis of the leg after radiation tx and three weeks later is slowly regressing.  Was diagnosed with klebsiella pneumoniae in his urine recently and is being treated with third generation cephalosporins via iv.  Mental statis has not improved.  Could it be hospital dementia or progression of cancer.  Multiple tests of brain and chest show no abnormalities.
Hi, Thanks for writing in. Urine infection due to klebsiella requires a culture and sensitivity test to be done. In this test we can know the type of klebsiella which has infected your father. Third generation cephalosporins are used for klebsiella infections. There are many other suitable antibiotics used in case cephalosporins do not cure the infection. In the culture and sensitivity report you will know which antibiotics will treat the infection with maximum response. Then that particular antibiotic might be given in recommended dose. For the mental status not improving, it will help to do a CT scan brain to know if he has any infection or other condition that might be causing his dementia like problems. Please do not worry.
