# Prevalence of Osteoporosis in Sickle Cell Disease

**NCT ID:** [NCT04299594](https://clinicaltrials.gov/study/NCT04299594)

## Key Facts

- **Status:** COMPLETED
- **Study Type:** OBSERVATIONAL
- **Target Enrollment:** 142
- **Lead Sponsor:** Hospices Civils de Lyon
- **Conditions:** Sickle Cell Disease
- **Start Date:** 2020-06-18
- **Completion Date:** 2021-12-18
- **CT.gov Last Update:** 2023-02-09

## Brief Summary

Sickle cell disease is the most common single-gene disease in the world. Its prevalence is increasing in France, with patients' life expectancy increasing into developed countries. It mainly affects populations originating from sub-Saharan Africa. Among the chronic bone complications associated with sickle cell disease, osteoporosis has previously been highlighted but remains a poorly known complication in this very particular context. A dedicated evaluation of osteoporosis and associated risk factors in sickle cell disease patients living in France may enable better bone management of these patients in the future, as this problem, specific to their disease, is likely to become more frequent as their life expectancy increases.

This is a prospective interventional and monocentric study whose objective is to describe the prevalence of osteoporosis in black patients with sickle cell disease in France

## Eligibility

- **Minimum age:** 20 Years
- **Maximum age:** 40 Years
- **Sex:** ALL
- **Healthy Volunteers:** No

```

## Arms

- **sickle cell disease patients** — 150 black patients with sickle cell disease living in France, 20 to 40 years old will be included in this study

## Interventions

- **Questionnaire** (OTHER) — For each subject recruited, will be collected for the study a questionnaire looking for a history of low energy fracture, and the origins of the patient (or relatives), as well as medical history, lifestyle (alcohol and tobacco consumption), weight and height. This data will be used for the secondary outcomes.

## Primary Outcomes

- **Bone mineral density** _(time frame: Day 1)_ — Bone mineral density is measured by systematic bone densitometry at 3 sites: lumbar spine, femoral neck and total hip. These data will be collected in the patient's medical record

## Locations (1)

- Hôpital Edouard Herriot, Lyon, France
