Registry Efficacy of Rituximab in Refractory SLE

Rituximab (RTX) treatment of lupus (SLE) patients remains a therapeutic option, especially in refractory SLE.  An observational UK cohort of 261 refractory SLE patients were followed in the BILAG-BR registry.

Patients starting biologic therapy between 2010 and 2015 were enrolled. Glucocorticoids were used in 93% of patients.

Response rates at 6 months were available for 68% of patients. After 6 mos. of RTX, median BILAG scores dropped from at baseline to 3 at 6 months (P < 0.0001).

During the same period the median SLEDAI-2K reduced from 8 to 4 (0-7) (P < 0.001).

Half (49%) of patients achieved a response along with a significant reduction of glucocorticoid dose to 7.5 mg at 6 months (P < 0.001).

Serious infections occurred in 10% patients.

Despite large randomized trials failing to show the efficacy of RTX in SLE (LUNAR https:/ and EXPLORER, uncontrolled observational data suggests possible efficacy and safety of RTX in refractory SLE.

Best of 2017: Death Rates from Lupus Remain Disproportionately High

The Annals of Internal Medicine reports that despite improving trends in mortality, death rates from systematic lupus erythematosus (lupus) remain high compared to those in the general population, and disparities persist between subpopulations and geographic regions. Underreporting of lupus on death certificates may have resulted in underestimates of mortality rates. 

Best of 2017: Are ANA Tests Unreliable?

Pisetsky and colleagues have reported in the Annals of Rheumatic Disease that ANA tests done on established SLE patients may yield surprisingly disparate results.

While ANA negative lupus was a problem of old assays and the loss of ANA positivity may be seen with chronicity or age, most rheumatologists believe that ANA positivity is an absolute requirement for the diagnosis of systemic lupus erythematosus.

Abatacept Misses in Lupus Nephritis

Dr. Richard Furie, MD, of Northwell Health in New York, presented the findings ofa large phase III trial of abatacept (Orencia) in lupus nephritis showing the agent failed to achieve a complete renal response.

Data presented at EULAR 2018 showed that at one year, a total of 35.1% of patients receiving abatacept achieved complete renal response, as did 33.5% of those randomized to placebo (P=0.73).
