| Abstract |
Psoriasis and psoriatic arthritis (PsA) are related inflammatory diseases with some shared genetic and environmental risk factors. It has been suggested that environmental factors, including infections, can trigger the development of PsA among psoriasis patients. The aim of this review was to systematically examine available data evaluating the effect of infections on the risk of developing PsA. A systematic search of the Cochrane Library, PubMed, Scopus, and Web of Science was conducted on March 16 2017, in accordance with the PRISMA statement. The following search terms were used along with "psoriatic arthritis": "infections", "risk", "bacteria", and "virus". Abstracts were reviewed and publications meeting the following criteria included: (1) Observational studies on psoriasis and PsA patients, including case-control, cohort, or ecologic studies and (2) presenting original data on the association between infections and PsA. The protocol for this systematic review was registered on PROSPERO (ID: 79432). Twenty-seven original studies presenting data on infections among PsA patients were included. Eight studies showed a statistically significant association between infections and PsA. In addition, seven studies reported mixed result with some statistically significant associations and five studies did not find statistically significant associations. This included studies of bacterial as well as viral pathogens and those of infections in general. The remaining seven studies lacked data to determine statistical significance. Out of all included studies, the total number of included patients was 933 PsA patients and 1611 controls. While the studies summarized did not all provide evidence supporting an association between infections and PsA certain trends emerged. The available data are inconsistent and further studies are needed to verify or refute this purported association. In particular, laryngeal infections and infections involving streptococci should be studied more carefully. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 12 November 2017.
All research outputs
#20,459,801
of 23,016,919 outputs
Outputs from Rheumatology International
#1,992
of 2,203 outputs
Outputs of similar age
#288,655
of 331,148 outputs
Outputs of similar age from Rheumatology International
#41
of 49 outputs
Altmetric has tracked 23,016,919 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,203 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.6. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 331,148 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 49 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
