Abstract:
All living patients transplanted between October 1985 and August
1990 under Faculty of Medicine Kidney Transplant Programme were studied for
PTE. Patents with PTE were defined as those with sustained haemoglobin of
greater or equal to 15g/dl. All weekly clinic follow up data sheets were reviewed.
We identified 12 patients (22.2%), 10 males and 2 females aged 18 to 50 with
PTE was between 3 and 24 months (mean 9.8 months)post- transplant. The
average maximum Hb% was 16.6g/dl. (range 15.4 to 18g/dl). PTE persisted for a
varying period from 2 months to 34 months. No patient had coincidental
leuxocytosis, thrombocytosis or splenomegely, and no other causes of secondary
polycythemia were evident clinically. The graft function was excellent before and
during PTE. (mean serum creatinine 1.34mg/dl, range 1-1.8mg/dl). All patients
but one were hypertensive 8 patients had received diuretic therapy. Cessation or
continuous administration of diuretics did not alter PTE. No surgical
complications like graft artery stenosis, obstructive uropathy were encountered in
our patients. No differences in the pre transplant blood transfusions compared to
other transplant patients could be detected. There was no apparent morbidity
associated with PTE in this group. Only one patient had three episodes of TIA. No
patient required phlebotomy. We conclude that the aetiology of PTE was probably
multi factorial in this group of patients. PTE was characterized by good graft
function and low frequency of complications.
