These recommendations are based on the consensus of clinical experts from a wide range of disciplines taking available evidence into account while balancing the benefits and risks of nonpharmacological, pharmacological, and surgical treatment modalities, and incorporating their preferences and values. Different backgrounds in terms of patient education or drug availability in different countries were not evaluated but will be important.

This is the first culture-independent study characterizing the gut microbial community in postinfectious arthritis. Although bacterial factors correlated with disease presence and clinical features of ReA, host genetics also appeared to be a major independent driver of intestinal community composition. Understanding of these gut microbiota-host genetic relationships may further clarify the pathogenesis of postinfectious spondyloarthritides.

At this time, reactive arthritis (ReA) is considered to be part of the spectrum of the spondyloarthritis, previously known as Reiter's syndrome, and refers to an infection induced systemic illness, characterized by a sterile synovitis occurring in a genetically predisposed individual, secondary to an infection localized in a distant organ/system, but also accompanied with multiple extra articular manifestations.

The most prevalent musculoskeletal diseases in Guatemala seem to be similar to those in most previous Community Oriented Program for Control of Rheumatic Diseases studies. Most subjects were still working. Further studies examining medical care received and impact on function can now be of interest.
