Extremely elevated serum alkaline phosphatase level upon treatment with teriparatide: a case report.
Article in Journal of medical case reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTeriparatide is a homolog of human parathyroid hormone (1-34), which is approved for the treatment of postmenopausal and glucocorticoid-induced osteoporosis. Several minor and transient side effects have been reported for teriparatide. However, controversial findings showed an increased risk of more significant adverse effects, including osteosarcoma in humans, although this finding has been demonstrated primarily in murine models. CASE PRESENTATION: We present a case of a 22-year-old Persian man with a previous history of systemic lupus erythematosus and glucocorticoid-induced osteoporosis. He had a previous history of joint hypermobility, idiopathic kyphoscoliosis, mitral valve prolapse, and bilateral congenital inguinal hernia, which were probably compatible with an inherited connective tissue disease. He was treated with teriparatide for 7 months because of glucocorticoid-induced osteoporosis. He was referred with a complaint of generalized bone pain and an extremely elevated serum alkaline phosphatase concentration of 6480 U/L (normal range, 80-306). A whole-body bone scan revealed a diffuse increased osseous uptake. Furthermore, the patient's systemic lupus erythematosus was clinically inactive on the basis of laboratory findings during this period. The medication was discontinued, and the patient's serum alkaline phosphatase level began to decline.
conclusionsTo the best of our knowledge, this is the first case of an osteoblast hyperactivation state observed during treatment with teriparatide. It appears that the osteoblastogenic effect of teriparatide might induce this condition and, most likely, osteosarcoma in certain populations. However, the potential influence of the patient's young age, systemic lupus erythematosus, underlying inherited connective tissue disease, and medication use cannot be ignored. The potential risk factors of this side effect shall be studied in specific subpopulations of patients with osteoporosis in future studies.
