INTRODUCTION: Hydroxyurea is an antimetabolite drug used in the treatment of myeloproliferative disorders. Common adverse effects include haematological, gastrointestinal cutaneous manifestations, and fever. Hydroxyurea-induced pneumonitis is unusual. CASE REPORT: A female patient was treated with hydroxyurea for polycythemia vera. She was admitted 20 days after commencing treatment with a high fever, productive cough, clear sputum and nausea. A chest CT-scan showed diffuse ground-glass opacities. Microbiological investigations were negative. The symptoms disappeared a few days after discontinuation of the drug and rechallenge led to a relapse of symptoms. CONCLUSION: Our case and 15 earlier cases of hydroxyurea-induced pneumonitis are reviewed. Two patterns of this disease may exist: an acute febrile form occurring within 1 month of introduction of hydroxyurea and a subacute form without fever. Even if uncommon, one should be aware of this complication of hydroxyurea.

Résumé : International audience
Chronic obstructive pulmonary disease (COPD) is the chronic respiratory disease with the most important burden on public health in terms of morbidity, mortality and health costs. For patients, COPD is a major source of disability because of dyspnea, restriction in daily activities, exacerbation, risk of chronic respiratory failure and extra-respiratory systemic organ disorders. The previous French Language Respiratory Society (SPLF) guidelines on COPD exacerbations were published in 2003. Using the GRADE methodology, the present document reviews the current knowledge on COPD exacerbation through 4 specific outlines: (1) epidemiology, (2) clinical evaluation, (3) therapeutic management and (4) prevention. Specific aspects of outpatients and inpatients care are discussed, especially regarding assessment of exacerbation severity and pharmacological approach.

Résumé : International audience
Introduction: Hydroxyurea is an antimetabolite widely used in the treatment of myeloproliferative diseases. Usual side effects are mainly hematological, gastrointestinal, neurological disorders and induced-fevers. More rarely, hydroxyurea-induced pneumonitis are reported. Case report: We report a case of a patient treated for polycythemia vera. She was admitted 20 days after introduction of hydroxyurea for a high fever, productive cough and clear sputum associated with nausea. Chest CT-scan found diffuse bilateral ground-glass opacities. The microbiological investigations were negative. Symptoms disappeared few days after discontinuation of treatment. Its reintroduction led to recurrence of symptoms. Conclusion: This additional case completes the 15 cases of hydroxyurea-induced pneumonitis described in the literature. Two forms of this disease seem to exist: an acute form with fever occurring in the month following introduction of hydroxyurea; and a chronic form without fever. Even if it is uncommon, pulmonologists should be aware of this complication.
