RESUMO
Australasia, encompassing Australia, New Zealand, and Papua New Guinea, has some of the highest prevalence's of inflammatory bowel disease (IBD) in the world. The way IBD medicine is practiced varies between and within these countries. There are numerous shared issues of IBD care between Australia and New Zealand, whereas Papua New Guinea has its' own unique set of circumstances. This review looks to explore some of the barriers to IBD care across the continent from the perspective of local IBD healthcare professionals. Barriers to IBD care that are explored include access to IBD multidisciplinary teams, provision of nutritional-based therapies, the prevalence and engagement of IBD-associated mental health disorders, access to medicine, access to endoscopy, rural barriers to care, Indigenous IBD care and paediatric issues. We look to highlight areas where improvements to IBD care across Australasia could be made as well as address research needs.
RESUMO
OBJECTIVE: This study examines the outcomes of de novo kidney transplants treated by a sequential protocol, designed to target the succession of immunologic events following engraftment. SUBJECTS: A total of 113 sequential live-donor recipients were randomized into 2 arms. Patients in arm A received prednisolone, cyclosporine, and sirolimus for 3 months (phase 1), followed by replacement of cyclosporine with mycophenolate mofetil (phase 2). Those in arm B (controls) received prednisolone/cyclosporine/mycophenolate mofetil throughout the study. The primary endpoints were patient and graft survival rates at 2 years. Secondary endpoints included biopsy-proven acute rejection, early and late graft function, hypertension, and adverse reactions. RESULTS: The 2-year intent-to-treat patient and graft survival rates (95.8% vs 91.4% and 94.6% vs 90.2%) were numerically but not significantly higher in arm A. The overall incidence of biopsy-proven acute rejection was numerically lower (13.5% vs 18.9%), yet it occurred exclusively with cyclosporine C2 levels below 770 ng/mL (P = .28). Mean time for serum creatinine to reach 132 micromol/L was significantly longer in arm A (7.3 vs 2.9 days). Graft function at 2 years (eGFR, 70.2 vs 55.9 mL/min) and number of drugs needed to control blood pressure (mean 1.7 vs 2.25) were significantly more favorable in group A. Significant adverse effects for patients in arm A included proteinuria (36.8% vs 18.6%), hyperlipidemia (peak cholesterol > 7.75 mmol/L in 32.9% vs 23.7% of patients) and thrombocytopenia (platelet count < 100 x 109/L in 32.9% vs 13.5 % of patients). CONCLUSIONS: The described protocol reduced the incidence of biopsy-proven acute rejection in patients after kidney transplant, particularly in those with adequate cyclosporine blood levels. Despite the significantly higher incidence of certain adverse effects (ie, delayed graft function, proteinuria, hyperlipidemia, and transient thrombocytopenia), patient and graft survival rates at 2 years were numerically, though not statistically, improved in patients in arm A. At 2-year analysis, compared with patients in the control arm (arm B), graft function significantly improved in patients in arm A, and the number of drugs needed to control blood pressure was significantly lower.
