RESUMO
Pregnancy is an important goal for many women with CKD or kidney failure, but important barriers exist, particularly as CKD stage progresses. Women with advanced CKD often have a limited fertility window and may miss their opportunity for a pregnancy if advised to defer until after kidney transplantation. Pregnancy rates in women with advanced kidney failure or receiving dialysis remain low, and despite the improved outcomes in recent years, these pregnancies remain high risk for both mother and baby with high rates of preterm birth due to both maternal and fetal complications. However, with increased experience and advances in models of care, this paradigm may be changing. Intensive hemodialysis regimens have been shown to improve both fertility and live birth rates. Increasing dialysis intensity and individualizing dialysis prescription to residual renal function, to achieve highly efficient clearances, has resulted in improved live birth rates, longer gestations, and higher birth weights. Intensive hemodialysis regimens, particularly nocturnal and home-based dialysis, are therefore a potential option for women with kidney failure desiring pregnancy. Global initiatives for the promotion and uptake of home-based dialysis are gaining momentum and may have advantages in this unique patient population. In this article, we review the epidemiology and outcomes of pregnancy in hemodialysis and peritoneal dialysis recipients. We discuss the role home-based therapies may play in helping women achieve more successful pregnancies and outline the principles and practicalities of management of dialysis in pregnancy with a focus on delivery of home modalities. The experience and perspectives of a patient are also shared.
RESUMO
AIM: Rates of simultaneous liver and kidney transplantation (SLKT) have increased, but indications for SLKT remain poorly defined. Additional data are needed to determine which patients benefit from SLKT to best direct use of scarce donor kidneys. METHODS: Data were extracted from the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA) database for all SLKT performed until the end of 2017. Patients were divided by pretransplant dialysis status into no dialysis before SLKT (preemptive kidney transplant) and any dialysis before SLKT (nonpreemptive). Baseline characteristics and outcomes were compared. RESULTS: Between 1989 and 2017, inclusive, 84 SLKT procedures were performed in Australia, of which 24% were preemptive. Preemptive and nonpreemptive SLKT recipients did not significantly differ in age (P = .267), sex (P = .526), or ethnicity (P = .870). Over a median follow-up time of 4.5 years, preemptively transplanted patients had a statistically equivalent risk of kidney graft failure (hazard ratio (HR) 1.83, 95% confidence interval [CI]: 0.36-12.86, P = .474) and all-cause mortality (HR 1.69, 95% CI: 0.51-5.6, P = .226) compared to nonpreemptive patients. Overall, 1- and 5-year survival rates for all SLKTs were 92% (95% CI: 86-96) and 60% (95% CI: 45-75), respectively. CONCLUSION: Kidney graft and overall patient survival were similar between patients with preemptive kidney transplant and those who were dialysis dependent.
