Introduction Chronic kidney disease (CKD) remains a prevalent public health problem that disproportionately affects minorities and the poor, despite intense efforts targeting traditional risk factors. Periodontal diseases are common bacterial plaque-induced inflammatory conditions that can respond to treatment and have been implicated as a CKD risk factor. However there is limited evidence that treatment of periodontal disease slows the progression of CKD. Methods/design We describe the protocol of the Kidney and Periodontal Disease (KAPD) study, a 12-month un-blinded, randomized, controlled pilot trial with two intent-to-treat treatment arms: 1. immediate intensive non-surgical periodontal treatment or 2. rescue treatment with delayed intensive treatment. The goals of this pilot study are to test the feasibility of conducting a larger trial in an ethnically and racially diverse, underserved population (mostly poor and/or low literacy) with both CKD and significant periodontal disease to determine the effect of intensive periodontal treatment on renal and inflammatory biomarkers over a 12-month period. Results To date, KAPD has identified 634 potentially eligible patients who were invited to in-person screening. Of the 83 (13.1%) of potentially eligible patients who attended in-person screening, 51 (61.4%) were eligible for participation and 46 enrolled in the study. The mean age of participants is 59.2 years (range 34 to 73). Twenty of the participants (43.5%) are Black and 22 (47.8%) are Hispanic. Discussion Results from the KAPD study will provide needed preliminary evidence of the effectiveness of non-surgical periodontal treatment to slow CKD progression and inform the design future clinical research trials.
