What This Study Did, in Plain Language

What Was Tested

This randomized controlled trial paper looks at Teriparatide and Parathyroid Hormone (PTH 1-84) in the context of osteoporosis and bone density.

The purpose of the present study was to determine whether the bisphosphonate alendronate could preserve or enhance bone density in patients previously treated with PTH.

Why It Was Studied

However, this effect is rapidly reversed when the treatment is stopped.

Markers of bone turnover included skeletal alkaline phosphatase, osteocalcin, and N-telopeptide.

Who Took Part

By PubMed's age tags, the people studied were middle-aged adults and older adults, women only.

How the Study Was Run

The design is described as randomized, double-blind and placebo-controlled.

Because people in this Teriparatide study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Neither the participants nor the staff measuring them knew who was on Teriparatide, so expectations could not easily colour the readings.

The comparison arm used a placebo, so changes seen with Teriparatide could be set against what happens without it.

BMD was measured in the femoral neck, lumbar spine, and whole body.

What Was Measured

Topics PubMed links to this paper include Alendronate, Alkaline Phosphatase, Biomarkers, Bone Density, Collagen, Collagen Type I and Femur.

What This Means in Plain Language

The paper is a randomized, double-blind and placebo-controlled study of Teriparatide and Parathyroid Hormone (PTH 1-84) in people with osteoporosis and bone density.

The publication is from 2000 (The Journal of clinical endocrinology and metabolism), a journal based in United States.

Our Notes on the Compounds

Teriparatide: A parathyroid hormone fragment, PTH(1-34), with human trials and approved-pen labeling; the research vial is not the approved pen.

Parathyroid Hormone (PTH 1-84): The 84-amino-acid hormone that raises blood calcium; full-length PTH (Natpara) has been used in hypoparathyroidism. Teriparatide is its 1-34 fragment.
