I am a 73 year old male who recently (five weeks ago) discovered a very low (12,000) platelet level. To date I have been treated with Prednisone and Rituxan. My counts have been variable but have never gotten above 49,000. In reviewing my recent medical history and blood tests this all seems to have started when I had a major UTI which required one day in the hospital. This occured three months ago. I was treated with Cipro which seems to have knocked out the UTI. though I did have a second bout three weeks later which was also treated with Cipro. All in all I had three rounds of the Cipro.
Is there any evidence that a UTI and Cipro can be the cause of ITP? If so is there any best treatment options since nothing seems to be working right now?
