Lupus Outcomes Influenced by Race/Ethnicity

A lupus registry from San Francisco County analyzed racial/ethnic differences in lupus manifestations and found significant differences in SLE manifestations among racial/ethnic groups. Researchers found that Blacks, Asians/Pacific Islanders (API), and Hispanics are more likely to develop severe manifestations following a diagnosis of SLE.

From their database, they identified 724 SLE patients, and identified specific features in different subgroups. 

  • Renal manifestations: were increased in blacks, APIs, and Hispanics [PR 1.74, PR 1.68, PR 1.35,  respectively]
  • Neurologic manifestations: were increased in blacks [PR 1.49 (95%CI: 1.12–1.98)]
  • Hematologic disease: was increased in blacks [PR 1.09 (95%CI: 1.04–1.15)] and APIs [PR 1.07 (95%CI: 1.01–1.13)]
  • Lupus nephritis: blacks, APIs, and Hispanics had a higher risk of developing nephritis [HR 2.4, HR 4.3, HR 2.3]
  • Thrombocytopenia was more likely in  blacks, APIs, and Hispanics [HR 2.3, HR 2.3, HR 2.2, respectively].
  • Anti-Phospholipid syndrome: a higher risk was seen in APIs and Hispanics [HR 2.5, HR 2.6, respectively].

FDA Grants Breakthrough Status for Potential Lupus Nephritis Drug

Obinutuzumab (Gazyva) has been granted Breakthrough Therapy Designation (BTD) by the U.S. Food and Drug Administration (FDA) for use in adults with lupus nephritis (LN). The drug made by Genentech, is going forward based on the Phase II NOBILITY study in adult patients with proliferative lupus nephritis (LN). Currently, there are no FDA-approved medicines for lupus nephritis.

Riociguat Fails in Systemic Sclerosis-Associated Digital Ulcers

Riociguat is an oral, selective soluble guanylate cyclase stimulator that has been studied in patients with digital ulcers (DU) due to systemic sclerosis (SSc) but study results show that short term (16 weeks) riociquat therapy does not sufficiently reduce the DU burden in SSc patients.

Nintedanib FDA Approved for Scleroderma Lung Disease

Last Friday, the US Food and Drug Administration approved Ofev (nintedanib) to slow the rate of decline in pulmonary function in adults with interstitial lung disease associated with systemic sclerosis or scleroderma, called SSc-ILD. ILD as a complication of SSc may lead to progressive loss of lung function and may be associated with a significant mortality risk. Prior to the approval of Olev, there were no FDA approved drugs for SSc-ILD.
