Objective: This study aimed to investigate the effectiveness and safety of single and repeated courses of rituximab in patients with refractory lupus. Methods: LESIMAB is a multicenter, retrospective, longitudinal study of lupus patients who have not responded to standard therapy and have been treated with rituximab. Response rates at six months and at follow-up were defined as efficacy outcomes. Complete response was defined as a SELENA-SLEDAI score ≤ two and a SELENA-SLEDAI Flare Index of zero. Partial response was defined as a reduction in the SELENA-SLEDAI score of ≥four points with no new or worsening of symptoms. Adverse events were collected. Results: Seventy-three (62.9%) of 116 patients achieved a response at six months (complete in 22 and partial in 51). Ninety-seven (77.6%) of 128 patients achieved a response after a mean follow-up of 20.0 ± 15.2 months (complete in 50 and partial in 47). High baseline SLEDAI score, previous treatment with ≥100 mg/day prednisone, and no history of severe hematologic flare were associated with response after the first treatment course. The median time to response was 6.5 months (95% CI, 5.0–8.0). Thirty-seven patients (38.1%) relapsed after the first infusion. The flare was severe in seven cases and mild to moderate in 29 cases. Serious infection rate was 12.6/100 patient-years. A schedule of four weekly doses was associated with more serious infections. Six patients died: two of infection and four of lupus complications. Conclusion: Rituximab can be an effective treatment option for patients who have refractory lupus with severe or life-threatening disease with an acceptable tolerance profile. [ABSTRACT FROM AUTHOR]

Summary: Our purpose was to assess the impact of a secondary prevention program for osteoporotic fractures in patients with fragility fracture and to determine its effect on long-term compliance with bisphosphonate treatment. Persistence with bisphosphonate use was 71%. Attending follow-up visits was the only variable significantly associated with adherence to bisphosphonates. Introduction: The aim of this study is to assess the impact a secondary prevention program for osteoporotic fractures in a prospective cohort of patients with at least one fragility fracture and to determine the effect of this intervention on long-term compliance with bisphosphonate treatment. Methods: All patients older than 50 years with a fragility fracture attended at the emergency department over a 2-year period were appointed for a clinical visit through a telephone call. Two follow-up controls at 4 and 12 months were scheduled. After a mean of 4 years, a telephone survey was conducted to assess compliance with treatment. Results: Of 683 eligible patients, 380 (55.6%) were visited at the hospital. Previous treatment with bisphosphonates was recorded in 17.9% of patients. DXA scan was considered normal in 61 patients and revealed osteopenia in 184 and osteoporosis in 135. Pharmacological treatment was indicated in 90% of patients (alendronate in 76%). Among 241 patients who participated in the survey, eight patients had new fractures (four were on treatment with bisphosphonates and four had discontinued treatment). Of 187 patients in which bisphosphonates were prescribed at the initial visit, 133 (71.1%) continued using bisphosphonates. Attendance of scheduled visits was associated with adherence to bisphosphonates (odds ratio, 3.33; 95% confidence interval, 2.99-3.67). Conclusions: The efficacy of the program to recruit patients was 55%. In patients visited at the hospital, treatment with bisphosphonates increased from 17.9% to 76%. Persistence with bisphosphonate use after a mean of 4 years was 71%. Attending follow-up visits was significantly associated with adherence to bisphosphonates. [ABSTRACT FROM AUTHOR]
