Abstract/Text
SUMMARY: Spinal kyphosis has been speculated to participate in the increased frequency of gastroesophageal reflux disease (GERD) in patients with osteoporosis. The present study provides further evidence that increases in lumbar kyphosis and number of vertebral fractures represent very important risk factors for GERD in patients with osteoporosis.
INTRODUCTION: Osteoporosis and spinal kyphosis have been speculated to participate in the increased frequency of gastroesophageal reflux disease (GERD). The present study examined whether GERD in patients with osteoporosis is affected by spinal factors including spinal kyphosis in the presence of oral pharmacotherapies.
METHODS: Subjects comprised 112 patients with osteoporosis (mean age, 78 years) who responded to the Frequency Scale for Symptoms of GERD (FSSG) questionnaire, regardless of complaints. Relationships between total FSSG score and number of vertebral fractures, angles of kyphosis, use of bisphosphonates and nonsteroidal anti-inflammatory drugs (NSAIDs), and total number of oral medicines per day were evaluated. Logistic regression identified factors associated with GERD.
RESULTS: Bisphosphonates and NSAIDs did not affect total FSSG score. Total FSSG score showed significant positive correlations with total number of medicines (r = 0.283, p = 0.0025), angle of lumbar kyphosis (r = 0.576, p = 0.0001), and numbers of thoracic vertebral fractures (r = 0.214, p = 0.0232) and lumbar vertebral fractures (r = 0.471, p < 0.0001). Angle of lumbar kyphosis and number of lumbar vertebral fractures were identified by multivariate analysis as indices affecting the presence of GERD.
CONCLUSION: Increases in angle of lumbar kyphosis and number of lumbar vertebral fractures may represent very important risk factors for GERD in osteoporotic patients.
