Weather and air-pollution linked to lupus flares

Different weather conditions appear to have organ-specific effects, say researchers

Changes in the weather and air pollution may contribute to organ-specific exacerbation in patients with SLE, a study shows.

Using data from the US Environmental Protection Agency (EPA), researchers examined the effects of fine particulate matter (PM2.5) concentration, temperature, relative humidity, winds, ozone concentration and barometric pressure on flare-ups associated with different organs in more than 1600 patients with SLE.

They calculated the average values for each factor 10 days prior to a patient visit.
