Prevalence of chronic obstructive pulmonary disease in Fez, Morocco: results from the BOLD study

OBJECTIVE

To present population-estimated prevalence of spirometrically confirmed chronic obstructive pulmonary disease (COPD) in adults (age ⩾40 years), living in the city of Fez, Morocco.

DESIGN

Following the Burden of Lung Disease (BOLD) methodology, population-based sampling plans were used for the recruitment of eligible adults. The study collected questionnaire data on respiratory symptoms, medical history, health status, exposure to risk factors for COPD and quality of life. Post-bronchodilator spirometry was performed and COPD and its stages were defined according to Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines.

RESULTS

Among 768 individuals with valid data and acceptable quality post-bronchodilator spirometry results, the overall prevalence of stage 1 or higher COPD was 12.6%. The prevalence of GOLD stage 2 or higher COPD was 7.9%. The population-estimated prevalence of lower limit of normal (LLN) modified stage 1 or higher COPD was 8% among non-smokers, and it increased with number of pack-years (17.8% for >20 pack-years vs. 3.8% for <10 pack-years). The prevalence of physician-diagnosed COPD was 3.2%; this was associated with an increase in smoking pack-years.

CONCLUSION

These results emphasise the urgent need to take necessary measures to reduce the prevalence of tobacco smoking.

Cholangiopathy and intrahepatic stones in sickle cell disease: coincidence or ischemic cholangiopathy?

Hepatic and bile duct involvement are common in sickle cell disease. This article reports the case of a young woman with cholangiopathy, homozygous sickle cell disease, and protracted anemia. We suggest that sickle cell disease was directly responsible for ischemic cholangiopathy through anoxia.
