Miliary tuberculosis in a Caucasian male transplant recipient and the role of intravenous immunoglobulin as an immunosuppressive sparing agent

Opportunistic infections are a common and anticipated accompaniment of transplantation, but are generally somewhat predictable in their timing and epidemiology. The authors report here a case of miliary tuberculosis occurring within 3 weeks of transplantation, in a patient not expected to be significantly at risk, and with a normal chest X-ray at the time of transplantation. A 25-year-old Caucasian male dialysis patient who received two paediatric kidneys as an en bloc renal transplant developed fever 3 weeks following transplantation; this eventually proved to be miliary tuberculosis. As well as antituberculous therapy and a significant reduction in the patient's conventional immunosuppression, intravenous immunoglobulin was used as anti-rejection prophylaxis. The case highlights the immunosuppressed status of dialysis patients prior to transplantation and the need for broad differential diagnosis in transplant recipients even in the absence of recognized epidemiological factors. The case also emphasizes the role of intravenous immunoglobulin as an anti-rejection therapy that does not add to the patient's immunosuppressive burden.
