Inclusion criteria

Inclusion criteria: Patients who meet all of the following conditions are eligible. 1) Patients who will be newly administrated glucocorticoids (higher than prednisolone 0.3mg/kg or equivalent) for systemic autoimmune diseases such as connective tissue diseases or patients for whom screening tests can be conducted using blood samples collected before starting glucocorticoids administration 2) Patients with performance status (Eastern Coop erative Oncology Group) 0 or 1 3) Written consent must be obtained from the patient or the patient's guardian. 4) Patient must be 20 years of age or older at the time of consent.

Exclusion criteria

Exclusion criteria: Patients who meet any of the following conditions are not eligible. 1) A history of continuous systemic administration of glucocorticoids within 6 months. (Inhaled and topical glucocorticoids are acceptable, and even systemic administration is acceptable if used within one month.) 2) Prior use of any of the following osteoporosis drugs a) bisphosphonate (BP) b) selective estrogen receptor modulators c) Activated VitD d) Ca preparations e) Denosumab f) Teriparatide g) Romosozumab 3) Patients who are unsuitable for the use of BP products in the following cases a) Patients with severe renal impairment (creatinine clearance of less than 30). b) Patients with oral problems and high risk of osteonecrosis of the jaw. 4) The patients have been taking supplements containing Ca or VitD. 5) There is scheduled surgery during this study. 6) Pregnant or lactating women and those who may or intend to become pregnant during this study (if pregnancy is suspected, a pregnancy reaction te st should be performed). 7) The high risk for an allergic reaction to this study drug. 8) There are a health, psychological, or social condition that interferes with participation in the study or evaluation of results, such as substance abuse. 9) Other conditions that may compromise patient safety in the conduct of the study or make compliance with the study protocol difficult.
