{"doi":"10.1177/0961203320966393","title":"Predictors of the start of declining eGFR in patients with systemic lupus erythematosus","abstract":"OBJECTIVE: To characterize the longitudinal trajectory of estimated glomerular filtration rate (eGFR) in patients with systemic lupus erythematosus (SLE) and identify predictors of the change in eGFR trajectory. METHODS: per year) states. The transition rate between states and the impact of clinical parameters were estimated by a Markov model. RESULTS: The analysis was based on 494 SLE patients. At a mean follow-up of 8.8 years, 347 (70.2%), 107 (21.7%), 33 (6.7%), and 7 (1.4%) patients had zero, one, two, and three state transitions, respectively. In patients with no transition, 37 (10.7%), 308 (88.8%), and 2 (0.6%) were in declining, stable, and increasing state, respectively. In patients with one transition, 43 (40.2%) changed from declining to stable state while 29 (27.1%) changed from stable to declining state. When patients were in a non-declining GFR state, those who were younger and African Americans were more likely to transition to a declining GFR state. In adjusted analyses, high blood pressure, C4 and low hematocrit were associated with change from non-declining to declining state. High urine protein-to-creatinine ratio also tended to be associated with change from non-declining to declining state. African American patients were less likely to move from declining to non-declining state. Use of prednisone was associated with change from declining to non-declining state. CONCLUSIONS: Patients with high blood pressure, low complement C4, low haematocrit, and high urine protein-to-creatinine ratio are more likely to have a declining eGFR trajectory, while the use of prednisone stabilizes the declining eGFR trajectory.","journal":"Lupus","year":2020,"id":89493,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":9,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.7394,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":37868,"name":"Suchi Saria","orcid":"0000-0002-7667-5210","position":1,"is_corresponding":false},{"id":278767,"name":"Michelle Petri","orcid":"0000-0003-1441-5373","position":2,"is_corresponding":false},{"id":285334,"name":"Laurence S.
