OBJECTIVES: Muscle strength is an important determinant of physical function in women with systemic lupus erythematosus (SLE). Serum biomarkers of inflammation, including interleukin-6 (IL-6) and C-Reactive Protein (CRP), are associated with differences in muscle strength among individuals without rheumatologic disease. We examined whether serum levels of IL-6 and CRP are associated with upper and lower extremity muscle strength among adult women with SLE. METHODS: One hundred thirty-six women with SLE participated in this cross-sectional study...

We describe the case of a 26-year-old African female who was treated successfully with belimumab in a case of severe membranous lupus nephritis and retinal vasculitis, resistant to first line therapy. She presented initially with chronic dacryoadenitis and screening showed nephrotic-range proteinuria. Biopsy of the kidney confirmed the diagnosis of membranous lupus nephritis. Clinical features (joint pain, dacryoadenitis, retinal vasculitis and lupus nephritis) in combination with serology (positive anti-double-stranded DNA (ds-DNA) antibodies, hypocomplementemia) confirmed the diagnosis of systemic lupus erythematosus (SLE)...

BACKGROUND: A false-positive screening result is associated with harmful treatment or follow-up costs. This study aimed to estimate the rate of false positive proteinuria with the dipstick in patients with systemic lupus erythematosus (SLE) taking hydroxychloroquine. METHODS: A total of 334 patients with a positive dipstick and confirmed by total urine protein with quantification assay were enrolled. The experimental group included those with SLE taking hydroxychloroquine, and the rest was the control group...

OBJECTIVE: Blood concentrations of hydroxychloroquine (HCQ) vary widely among patients with systemic lupus erythematosus (SLE). A pharmacokinetic/pharmacodynamic relationship has been found in different situations, and a very low blood concentration of HCQ is a simple marker of nonadherence to treatment. Therefore, interest in blood HCQ concentration measurement has increased, but little is known about factors that influence blood HCQ concentration variability. This study was undertaken to analyze determinants of blood HCQ concentrations...

OBJECTIVES: Growing evidence suggests that vitamin D plays a key role in the pathogenesis and progression of autoimmune diseases, including systemic lupus erythematosus (SLE). Recent studies have found an association between lower serum 25-hydroxyvitamin D (25(OH)D) levels and higher SLE activity. We studied the relationship between 25(OH)D levels and Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score, and we assessed for the first time the role of vitamin D in predicting SLE flare-ups...

Patients with multiple comorbidities often develop decreased intestinal motility resulting in abdominal distention. A variety of etiologies such as electrolyte abnormalities, medications, and sometimes unusual anatomical pathologies are responsible for this distention. Cecal bascule represents an exceedingly rare anatomical variance that leads to abdominal distention, and mimics a potentially isolated cecal distention. This rare diagnosis, if missed, can lead to severe complications. We present a case of a 64-year-old male with a past medical history of emphysema, rheumatoid arthritis for which he was recently started on Plaquenil, and alcohol abuse who was admitted with a diffuse rash and was noted to have worsening abdominal distention...

The discovery that circulating nucleic acid-containing complexes in the serum of autoimmune lupus patients can stimulate B cells and plasmacytoid dendritic cells via Toll-like receptors 7 and 9 suggested that agents that block these receptors might be useful therapeutics. We identified two compounds, AT791 {3-[4-(6-(3-(dimethylamino)propoxy)benzo[d]oxazol-2-yl)phenoxy]-N,N-dimethylpropan-1-amine} and E6446 {6-[3-(pyrrolidin-1-yl)propoxy)-2-(4-(3-(pyrrolidin-1-yl)propoxy)phenyl]benzo[d]oxazole}, that inhibit Toll-like receptor (TLR)7 and 9 signaling in a variety of human and mouse cell types and inhibit DNA-TLR9 interaction in vitro...

IMPORTANCE: Hydroxychloroquine-induced pigmentation is not a rare adverse effect. Our data support the hypothesis that hydroxychloroquine-induced pigmentation is secondary to ecchymosis or bruising. OBJECTIVE: To describe the clinical features and outcome of hydroxychloroquine (HCQ)-induced pigmentation in patients with systemic lupus erythematosus (SLE). DESIGN, SETTING, AND PARTICIPANTS: In a case-control study conducted at a French referral center for SLE and antiphospholipid syndrome, 24 patients with SLE, with a diagnosis of HCQ-induced pigmentation, were compared with 517 SLE controls treated with HCQ...

Offspring of women with anti-SSA/Ro-SSB/La antibodies are believed to be at risk for congenital heart block (CHB). Whether this risk can be reduced, and what constitutes standard of care treatment is, however, unclear. The objective of this review therefore was to determine whether currently proposed standard of care treatments to avoid CHB in offspring of mothers at risk are evidence-based. To do so, we conducted a review of the literature under appropriate keywords and phrases in Medline/PubMed and Google Scholar for the years 2000-2013...
