IgG-related disease: an atypical presentation of steroid-responsive renal mass.

IgG-related disease (IgG-RD) is a systemic fibroinflammatory disease characterised by dense lymphoplasmacytic infiltration rich in IgG-positive plasma cells, storiform fibrosis and obliterative phlebitis. Serum IgG levels are typically elevated but half of the patients had normal serum IgG levels. IgG-RD represents a spectrum of diseases that involve various organs such as the pancreas, liver, kidneys, and salivary glands often manifesting as diffuse organ enlargement or a mass-like lesion mimicking cancer.

Degraded microarchitecture by low trabecular bone score is associated with prevalent vertebral fractures in patients with systemic lupus erythematosus.

Purpose: Recently, trabecular bone score (TBS) has emerged as an important supplementary assessment tool in osteoporosis diagnosis and management. The high incidence of fragility fracture within the non-osteoporotic range of bone mineral density (BMD), among systemic lupus erythematosus (SLE) patients, highlights the crucial role of bone microarchitecture in osteoporosis. This study aimed to evaluate whether TBS identified existing vertebral fractures (VF) more accurately than BMD in SLE patients.

Maternal and perinatal outcomes of pregnancies in systemic lupus erythematosus: A nationwide population-based study.

Objectives: Systemic lupus erythematosus (SLE) is an autoimmune disease that develops mainly in women of reproductive age. We aimed to explore the risk of pregnancy complications in Asian patients with SLE.

Methods: From January 2005 to December 2014, we conducted a nationwide case-control study, using Taiwan's National Health Insurance Research Database.
