The Microbiome and Lupus Connection Reviewed

In the current issue of the New England Journal of Medicine, Drs. James Rosenbaum and Gregg Silverstein review the pathogenesis of systemic lupus erythematosus (SLE) from the viewpoint of a dysbiolsis.

The complexity of the trillions of organisms that constitute our microbiome underscores its multiplicity of functions, including nutrient, metabolic and immune shaping functions.

It is therefore not surprising to consider new lines of evidence point to the potential of a dysbiolsis contributing to the pathogenesis of SLE.  Recent evidence includes:

  • Manfredo Vieira et al. has shown that the gram-positive bacterium Enterococcus gallinarum has a causative role in a murine lupus model.
  • Oral antibiotics may extend the lifespan of lupus prone mice and lower autoantibody production
  • Lupus-prone mice have increased bowel permeability that can be diminished with certain antibiotics.
  • Certain bacteria such as E. gallinarum, can induce cells to produce interferon-α and beta-2 glycoprotein 1 and induce  lupus-like disease in mice.

They speculate whether these findings may drive and contribute to lupus and whether the microbiome could be therapeutically manipulated. Clearly, more research is needed.

Genetic Diagnosis for Previously Undiagnosed Disorders

The NEJM has reported the NIH's Undiagnosed Diseases Network (UDN) study results of genetically identifying new diseases from prospectively followed persons with undiagnosed disorders. The UDN was formed in 2014 as a network of seven clinical sites, two sequencing cores, a coordinating center, central biorepository, a metabolomics core, and a model organisms screening center. It was established to apply a multidisciplinary model in the evaluation of the most challenging cases and to identify the biologic characteristics of newly discovered diseases.

SLE and Risk of Malignancy

The risk for cancer in systemic lupus erythematosus (SLE) patients has been inconsistently studied.  A new metanalysis shows that SLE has an increased risk for 16 specific cancers and decreased risk for prostate cancer and cutaneous melanoma. 

The Benefits of a Lupus Clinic

A comparative cohort study assessing the quality of care in patients with systemic lupus erythematosus (SLE) suggests that a dedicated lupus clinic has better quality measure performance compared to lupus management in a general rheumatology clinic.

A study from Rush University enrolled 150 consecutive SLE patients - with 73 followed in the general rheumatology clinic and 77 followed in a dedicated lupus clinic. 

Diagnosing Early Lupus from Mimics

A multicenter study of early systemic lupus erythematosus (SLE) patients examined manifestations at disease onset and found that certain clinical features can help to distinguish early SLE from other SLE‐mimicking conditions. 

High CV Risk in Lupus

Patients with systemic lupus erythematosus (SLE) remain at risk for accelerated atherosclerosis, and important questions have yet to be answered, British investigators reported.
