All articles are anonymously peer reviewed, and acceptance notification is normally sent within three months of receipt by the journal. Copyright for articles will be automatically transferred to the Brazilian Journal of Nephrology (Jornal Brasileiro de Nefrologia). The content of the material sent for publication may not be previously published or submitted to other journals. To publish, even in part, in another journal, written approval from the editors is necessary. The concepts and declarations contained in the referred manuscripts are the complete responsibility of the authors.


The Brazilian Journal of Nephrology (Jornal Brasileiro de Nefrologia) accepts papers written in Portuguese and English, preferably in English. The submission of manuscripts in both languages ??is stimulated.

Original Articles

These should present unpublished results from research, constituting complete studies that contain all relevant information so that the reader may reproduce the study or evaluate its results and conclusions. They are presented in one of two sections: basic science and clinical research. The manuscripts are classified in six disciplines of Nephrology: a) Acute Renal Injury; b) Chronic Kidney Disease; c) Dialysis and Extracorporeal therapies; d) Epidemiology and Clinical Nephrology; e) Pediatric Nephrology; f) Renal Transplantation.

Review Articles

Reviews are preferably requested to specialists in a particular area (by the Editor). The objective of these articles is to express and critically evaluate the knowledge available on a specific topic, commenting on studies from other authors and using a broad reference base, or on occasion, responding to a spontaneous demand concerning a specific topic.

The manuscript should contain:

  • abstract, not necessarily structured, of no more than 250 words;

Manuscripts are preferably requested by the Editor to a specialist in a particular area, dedicated to the comprehensive presentation and discussion of scientific issues in the field of nephrology. Should clearly formulate a scientific object of interest, logical reasoning, theoretical and methodological review of the studies consulted. This type of article should be elaborated by experienced researchers in the concerned field or by experts of recognized competence.

The manuscript should contain:

A case report should have at least one of the following characteristics to be published in the Journal: a) special interest to the clinical research community; b) a rare case that is particularly useful to demonstrate a mechanism or a difficulty in diagnosis; c) new diagnostic method; d) new or modified treatment; e) a text that demonstrates relevant findings and is well documented and without ambiguity.

The manuscript should contain:

  • abstract, not necessarily structured, of no more than 250 words;
