Although many manifestations of giant cell arteries are increasingly recognized, little attention has been paid to respiratory symptoms associated with this disorder. We report the cases of 16 patients with giant cell arteritis who had prominent symptoms related to the respiratory tract including cough, sore throat, and hoarseness. These symptoms were the initial finding in 10 patients and obscured the diagnosis in some instances, but resolved quickly when corticosteroids were given. It is estimated that 9% of patients with giant cell arteritis have prominent respiratory tract symptoms, which are the initial manifestation in 4%. This disorder should be considered in an older patient with a new cough or throat pain without obvious cause.

The alleged prescribing habits of 44 randomly chosen Dutch family doctors were compared with those of 59 family doctors from England and Wales by inference from their prescribing responses to 10 hypothetical patients presented in a mail survey. The response options were: (a) neither prescribing nor advising over-the-counter (OTC) medication; (b) advising OTC medication; or (c) prescribing medication. Although sample numbers were small, the sample appeared to be broadly representative of GPs in each country. There were significant differences in stated treatment habits between doctors of the 2 countries, especially with regard to treatment of sore throat, temporal arteritis, epigastric pain, travellers' diarrhoea and polyarthralgia. The results suggest substantial differences in management of common general practice problems exist between England/Wales and The Netherlands, despite their similar healthcare systems. These differences point to the need for rationalisation of management through improved education and audit.

Giant cell arteritis (GCA) is a common vasculitis of unknown cause that affects persons in middle age and older. Its incidence rises with increasing age. The inflammatory lesions involve larger arteries that contain an abundance of elastic tissue. Although cranial symptoms such as headache, tender scalp, jaw claudication and visual symptoms are common, the disease presents in many different fashions, often with symptoms not directly related to the arteries. These latter presentations include fever, severe malaise, polymyalgia rheumatica, high erythrocyte sedimentation rate and anemia, thrombocytosis, sore throat, and hepatic dysfunction. GCA appears to have a self-limited course, but is also characterized by relapses and recurrences. Visual loss due to occlusion of the optic arteries is the most important early manifestation and aortic aneurysm is the most important late complication. Patients respond promptly to varying doses of glucocorticoids but drug side effects are common.

Some arguments are in favor of the role of Chlamydia in the pathogenesis of atherosclerosis and some vasculitis. Illustrating this possible relation, we report the case of a patient developing consecutively a Chlamydia psittacci infection and a temporal arteritis. A 73-year-old woman, with no significant medical history, was hospitalized for constitutional symptoms. Three weeks before, she had described fever and sore throat of two days' duration. Since that time, she had remained exhausted and developed a mild intermittent claudication of the jaws. Clinical examination was poor. A biological inflammatory syndrome was noticed. Chest X-ray revealed bilateral interstitial opacities. The titer of anti-C. psittaci antibodies was significant (positive 1g G at 1/2048). Soon after initiation of doxycycline, a temporal arteritis biopsy was performed, due to the persistence of clinical symptoms and high inflammatory syndrome, conclusive for the diagnosis of temporal arteritis. Corticotherapy was added to antibiotic therapy, resulting in the decrease of inflammatory syndrome and an improvement in the general status of the patient. X-ray opacities decreased in three weeks. Serological control after three months showed a decrease of the titer of anti-C. psittacci antibodies to 1/256, confirming the initial diagnosis of Chlamydia pneumopathy. Our observation could provide one more argument for the role of bacteria-like Chlamydia in the pathogenesis of vascular diseases. Prospective seroepidemiological and molecular biology studies could allow us to clarify the association between Chlamydia infections and inflammatory vasculitis-like temporal arteritis.

Temporal arteritis is a chronic vasculitis of medium and large-size vessels and involves particularly extracranial branches of the aortic arch arteries. Authors report the case of a 73-year-old woman who presented to the hospital after looking for medical counselling three times because of unexplained fever, fatigue, nonproductive cough, and throat pain. She already completed two antibiotic prescriptions. This 3-week history completed in the last days with temporal bilateral headache and visual disturbance. Physical examination was notable for fever and bilateral thickened tender temporal arteries. The erythrocyte sedimentation rate was elevated. A biopsy specimen of the left temporal artery confirmed the diagnosis of giant cell temporal arteritis. The diagnostic suspicion of this disease is clinical and usually simple, but in 10% there are throat pain, non-productive cough and fever which are misunderstood as superior respiratory tract infections leading to diagnosis and treatment delay.
