Plasma prostaglandin E 2 concentration in nephrotic syndrome

Abstract

of palliative shunts for coarctation repair, pulmonary artery banding, or ductus arteriosus ligation often result in local damage to one or two ribs, which may be accompanied by spreading of ribs and distortion of the bony architecture. The follow-up studies available in our patients suggest that prostagtandin periostitis may be a benign, self-limited process with no apparent effect on subsequent bone growth and development: Complete resolution occurred in most of the bones reexamined six months to one year later. Bone resorption secondary to prostaglandins is well documented. 6.7 Periosteal new bone formation in dogs in response to long-term (14 to 30 days) PGE~ infusions has been experimentally demonstrated. 8 Recent work has suggested that alterations in the ratio of PGE1 and PGF may result in periosteal new bone formation. 7'9 In addition, inhibition of prostaglandin production with salicylates significantly reduced bone destruction and new bone formation in rabbits with experimental osteomyelitis. 7 This research affords a theoretical basis for the periosteal changes noted. Prostaglandin-induced periostitis must be considered in any infant receiving PGE~ who develops periosteal reaction of irregular, asymmetric distribution. Other causes related to postoperative trauma, metabolic bone disease, Caffey disease, battered child syndrome, and hand-foot syndrome have their own distinctive clinical findings and must be excluded? ~ It would also be prudent to investigate possible infectious causes such as congenital syphilis.
