heroin and Osteoporosis

Osteoporosis has been associated with several disorders; however, there have been only a limited number of reports on heroin-induced osteoporosis. We report a rare case presented with bilateral femoral neck insufficiency fractures without trauma history, caused by heroin-induced osteoporosis. We collect sufficient clinical data and further shed light on the potential mechanism of how heroin affects bone formation and decreases bone density.. A 55-year-old male patient with normal body mass index (BMI) suffered from bilateral hips pain gradually without trauma history. He had intravenous heroin addiction for more than 30 years. Radiography revealed bilateral femoral neck insufficiency fractures. Laboratory tests showed elevated alkaline phosphatase levels (365 U/L) and decreased inorganic phosphate (1.7 mg/dL), calcium (8.3 mg/dL), 25-(OH)D3 (20.3 ng/ml) and testosterone levels (2.12 ng/ml). Magnetic resonance imaging (MRI) revealed increased signals on STIR images over the sacral ala and bilateral proximal femur, and multiple band-like lesions at the vertebrae of the thoracic and lumbar spine. Bone densitometry revealed osteoporosis with a T score of minus 4.0. The screen for urine morphine was positive (> 1000 ng/ml). Through assessment of the patient, the diagnosis was insufficiency fractures of bilateral femoral neck caused by opioid-induced osteoporosis. After hemiarthroplasty, regular medication with vitamin D3 and calcium, and detoxification treatment, and the patient recovered well after 6 months of follow-up.. The aim of this report is to highlight the laboratory and radiology findings in a case of osteoporosis caused by opioid addiction and discuss the potential pathway by which osteoporosis is induced by opioids. When an unusual osteoporosis presents with insufficiency fractures, heroin-induced osteoporosis should be considered.

Risk factors for osteoporosis are prevalent in chronic heroin users who often start using opiates in their late teens. This study was the first to evaluate bone mineral density (BMD) in relatively young heroin-dependent patients on injectable heroin maintenance.. Using cross-sectional design, BMD was assessed in a convenience sample of 19 patients (mean age ± SD = 33.9 ± 5.4; 13 men) prescribed injectable diacetylmorphine for heroin dependence. BMD of the lumbar spine and proximal femur was measured by dual-energy X-ray absorptiometry. Substance use and menstrual history, psychopathology and risk factors for low BMD were assessed by questionnaire-based interviews.. According to World Health Organisation criteria almost three-quarters (74%) of the sample had osteopenia (n = 11) or osteoporosis (n = 3) at one or more sites of measurement. All patients showed multiple risk factors for bone loss, with pack-years of tobacco use and years of heroin use reaching marginally significant associations with spine Z-scores. Moreover, BMD Z-scores correlated significantly negatively with increasing age at all sites, indicating that the older the patient, the greater the BMD deviation from an age-controlled population.. Prolonged heroin dependence appears to be associated with lower-than-normal bone mass already at early age and these individuals might be at greater risk for fracture with advancing age. The negative correlation of age-adjusted Z-scores with increasing age suggests factors other than age for low BMD in this population (e.g. smoking, heroin use). Prospective studies are warranted to determine the necessity for diagnostic and preventive measures.
