In recent years, Zika, Chikungunya, Dengue, West Nile Fever, and Yellow Fever epidemics have generated some concerns. Besides difficulties related to vector control, there are challenges related to behavior of pathologies not yet fully understood. The transplanted population requires additional care due to immunosuppressive drugs. Furthermore, the potential risk of transmission during donation is another source of uncertainty and generates debate among nephrologists in transplant centers. Do the clinical outcomes and prognoses of these infections tend to be more aggressive in this population? Is there a risk of viral transmission via kidney donation? In this review article, we address these issues and discuss the relationship between arbovirus and renal transplantation.
Resumo Entre as terapias renais substitutivas, o transplante renal preemptivo (TRP) apresenta os melhores resultados clínicos, sociais e econômicos. No entanto, ainda é raramente escolhido como primeira terapia para pacientes com falência renal irreversível. Foram desenvolvidas iniciativas em diferentes partes do mundo para identificar as razões pelas quais o TRP ainda não é amplamente utilizado e para facilitar o acesso de pacientes com doença renal em estágio terminal às vantagens associadas ao mesmo. Este artigo aborda as principais vantagens e dificuldades do TRP e discute quando ele deve ser indicado e como preparar potenciais receptores para o TRP.
Renouncement of renal replacement therapy (RRT) is a medical dilemma. This review covers the concept, the magnitude, the prognosis, and discusses strategies and management approaches about this subject in patients with CKD and AKI. Evidence suggests that refusal is more frequent and carries a more guarded prognosis than withdrawal of RRT. When RRT is not expected to be beneficial in terms of survival or quality of life, conservative treatment and palliative care are alternatives. We review the historical evolution of guidelines about renouncement of RRT and palliative care, and highlight the absence of specific recommendations in Brazil. However renouncement of RRT may be ethically and legally accepted in Brazil, as the right to a dignified death. Longer life expectancy, economic pressures, and greater awareness will require a more detailed discussion about indications and sustainable use of RRT, and possibly the elaboration of national guidelines.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
