Donor proteinuria in the absence of other significant factors influencing organ acceptance, appears to be of little importance in influencing graft outcome. Larger studies are required to further examine this. 254 AMBULATORY VS OFFICE BLOOD PRESSURE MONITORING IN RENAL TRANSPLANT RECIPIENTS J AHMED, V OZORIO, M FARRANT, W VAN DER MERWE North Shore hospital, BGJ398 purchase Auckland,

New Zealand Aim: To investigate correlation between office (OBPM) and ambulatory (ABPM) blood pressure monitoring in renal transplant recipients (RTR). Background: Hypertension is common post renal transplant and has adverse effects on cardiovascular and graft health. Nocturnal hypertension, which is also implicated in poor outcomes, can only be diagnosed via ABPM. ABPM is increasingly being recognized as a better method of measuring BP with discrepancies between office (oBP) and ambulatory BPs (aBP) being noted in RTR. Methods: We undertook a retrospective analysis of 98 renal transplant recipients (RTR) (40% female, average age 55) in our unit and compared oBP and aBP recordings. Baseline demographic data was recorded along with Small molecule library eGFR, proteinuria, medications and co-morbidities. Results: ABPM revealed 28.5% and 13.2% had concordant normotension and hypertension

respectively. There was a discordance between OBPM and ABPM in 58% of patients with 53% due to masked hypertension (of which 34% were due to isolated nocturnal hypertension) and 5% had white coat hypertension. Overall mean systolic BP was 3.6 mmHg (0.5–6.5) and diastolic BP 7.5 mmHg (5.7–9.3) higher via ABPM than

OBPM (95% confidence). This was independent of eGFR, proteinuria, transplant time/type and comorbidities. 41% of patients had their management changed after results from ABPM. Conclusions: There is a significant discordance between OBPM and ABPM with a predominance of masked hypertension. The results of ABPM changed management Methocarbamol in a significant proportion of patients. ABPM is the only means to diagnose nocturnal hypertension and should be routinely offered as part of hypertension management of RTR. 255 ANNUAL SKIN CANCER INCIDENCE IN RENAL TRANSPLANT RECIPIENTS 1997–2013: A SINGLE CENTRE EXPERIENCE G DAS1, B TAN1,2, K NICHOLLS1,3 Departments of 1Nephrology and 2Dermatology, The Royal Melbourne Hospital, Melbourne; 3Department of Medicine, The University of Melbourne, Melbourne, Australia Aim: To evaluate annual incidence of skin cancers (SC) in renal transplant recipients (RTR) in our hospital (RMH) from 1997 to 2013. Background: ANZDATA data indicates that RTR have a 100 fold increased risk of developing SCC. There is no clear evidence that SC incidence has fallen over time, or with different immunosuppressive regimens. Methods: We retrospectively studied RMH patients transplanted between January 1997 and December 2013, extracting data from medical records, our departmental database, and pathology reports.
