Objectives: 

To describe the characteristics and the prevalence of respiratory diseases in the homeless population in Marseilles.

Methods: 

Snapshot study 2 nights in January 2005, by a medical team of 40 persons including infectious diseases senior, residents and fellows, pneumologists, nurses, X-ray technicians in the 2 shelters in Marseilles. Homeless were interviewed, examined, and received care. Blood was sampled for cell count, detection of bacteraemia and antibodies to Chlamydia, Mycoplasma, Legionella pneumophila, and Coxiella burnetii. A chest-X radiograph was performed.

Results: 

A total of 221 homeless persons were enrolled. The mean age was 41 years ± 13 and 94% of the population were men; 38% were born in North Africa, 37% in France, and 14% in Central/Eastern Europe; the subjects have been homeless less than 7 months in 43%, from 7 to 12 months in 12%, from 13 to 24 months in 8.1%, and more than 24 months in 36%. Among study population, 77% were current smokers, 65% were alcohol abusers, 2 persons were infected by HIV, 30% reported prior contact with tuberculosis patients (in shelter 23% and in family and relatives in 77%). The most frequent reported symptoms were weight loss (43%), chronic cough (39%), sputum production (33%), sweats (16%), and dyspnoea (16%). Clinical diagnosis was established as bronchitis in 19%, chronic obstructive bronchitis in 17%, asthma in 2%, and acute pneumonia in 1%. All blood cultures; as well as serological tests were negative. Chest radiographs performed in 219 persons and subsequently analysed showed abnormalities in 14 persons (6%). Of these 14 homeless persons, 4 have not been reached for follow up and 10 have hospitalized for further investigations. The final diagnosis made were active tuberculosis in 2 persons (1%) who have been homeless for 10 and 11 years, sequels of tuberculosis in 4 (2%), lung cancer in 1 (0.5%), obstructive lung disease in 1 (0.5%), acute pneumonia in 1 (0.5%), and no specific diagnosis in 1 (0.5%). A specific care was given for each of these homeless persons.

Conclusion: 

This snapshot investigation revealed that 6 % of this homeless population had life threatening respiratory diseases in which 1% had active contagious tuberculosis. Systematic chest radiography could be an efficient strategy to rapidly identify and prevent the spread of this transmissible disease among homeless population of shelters.
