If you qualify and want to join this study, you will go to the clinic for your regular doctor visits. No extra visits are needed. On these visits, we will collect information from your medical records. This includes your year of birth, gender, race and ethnicity, if you smoke, your medical history like lupus nephritis diagnosis and biopsy results, treatments you had for lupus nephritis, other medicines you take, other health problems, blood pressure, height, weight, hospital stays, and blood test results. We will collect this information from up to 12 months before you started belimumab (and biopsy results from up to 24 months before), when you started belimumab, and then every 6 months at your regular visits for up to 48 months. We will also collect data at your 5-year (60-month) visit. You will be asked to do two short surveys about your tiredness and how lupus affects your life. You will take these surveys when you join, then every 6 months up to 24 months, and then once a year until 5 years after starting belimumab. Each survey takes about 15 minutes and will be done on a tablet given by the study staff. You will get $25 for each survey you finish. You can get paid for up to seven surveys, or $175 total, after the study staff checks that you completed them.
