Joint Pain Linked to Increasing Temperature, Not Rainfall

Every rheumatologist knows and every rheumatic patient woes about the havoc weather inflicts on joint pains. Yet, research on this issue has seldom confirmed these impressions.  A novel new look has shown by linking online search terms with published weather conditions that increasing climate temperatures increased rates of hip and knee pain (searches), while precipitation had no effect.

Researchers explored this issue by linking online search terms and behavior (as a surrogate for patient symptomatology) with local weather data for temperature, relative humidity, barometric pressure, and precipitation from 50 US metropolitan areas.

They found that for temperatures between -5°C and 30°C, search volumes for hip pain increased by 12 index points, and knee pain increased by 18 index points. Precipitation had a negative effect on search volumes for these terms. Higher temperatures >30°C, were linked with a modest reduction in arthritis related pain searches (-7 index points).  Such patterns were not observed with pain searches unrelated to the musculoskeletal system (e.g., stomach pain).

The authors postulated that these observations may be related to relative changes in physical activity levels associated with meteorological conditions.

Update on Osteoporosis

This session was an update on the management of osteoporosis given by Professor Christian Roux from France.

He emphasised the use of composite risk score like the FRAX. He highlighted that the risk of vertebral fracture is increased by both the recency and severity of previous vertebral fracture. So it is important that those with vertebral fractures are followed up and treated appropriately to prevent subsequent fractures.

Adults with osteoarthritis (OA) of the knee who frequently experienced restless sleep were less likely to engage in potentially beneficial moderate-to-vigorous physical activity, analysis of data from the Osteoarthritis Initiative found.

FDA Approves Denosumab for Glucocorticoid-Induced Osteoporosis

Amgen announced that the U.S. Food and Drug Administration (FDA) has approved the use of Prolia® (denosumab) for the treatment of glucocorticoid-induced osteoporosis (GIOP) in men and women at high risk of fracture, defined as a history of osteoporotic fracture, multiple risk factors for fracture, or patients who have failed or are intolerant to other available osteoporosis therapy.

Bisphosphonate Drug Holidays May Result in Fractures

A report in Endocrine Practice shows that drug holidays from bisphosphonates results in a 15% risk of fractures.  (Citation source: http://bit.ly/2FHbFwp)

USPSTF Recommendations on Vitamin D, Calcium Supplementation to Prevent Fractures

The U.S. Preventive Services Task Force (USPSTF) concludes current scientific evidence is insufficient regarding the use of vitamin D and calcium, alone or in combination, to prevent fractures in men and premenopausal women. The USPSTF recommends against daily supplementation with 400 IU or less of vitamin D and 1,000 mg or less of calcium to prevent fractures in postmenopausal women. Current scientific evidence is insufficient regarding the use of vitamin D and calcium at doses greater than 400 IU of vitamin D and greater than 1,000 mg of calcium in postmenopausal women.
