Comparison of two oral antibiotics, roxithromycin and amoxicillin plus clavulanic acid, in lower respiratory tract infections.

In a randomized, multicenter, open-label study, 490 ambulatory adult patients with lower respiratory tract infection (LRTI) were randomized to roxithromycin (ROX) 150 mg b.i.d. orally (n = 244) or amoxicillin plus clavulanic acid (AMX + CA) as 500 mg AMX + 125 mg CA t.i.d orally (n = 24). Clinical results were analyzed in 477 patients with acute bronchitis (79%), chronic bronchitis (CB) (14%), and pneumonia (7%). There were significantly more patients with underlying disease (cardiovascular diseases, p = 0.045; and alcoholism, (p less than 0.001), and more patients over the age of 65 years (p = 0.045) in the ROX group. Overall clinical efficacy was similar in both groups: 88% (206:235) in the ROX group and 85% (205:242) in the AMX + CA group. Side effects were reported in 67 cases (28%) in the AMX + CA group and in 21 cases (9%) in the ROX group (p less than 0.0001), causing withdrawal in 21 and three cases, respectively (p less than 0.001). Thus, despite being administered to a significantly older and more ill group of patients with LRTI, roxithromycin was as effective as amoxicillin plus clavulanic acid and better tolerated.

[Peliosis hepatis in dermatomyositis treated with azathioprine and corticoids].

We report a case of peliosis hepatis in a 47-year old male patient with dermatomyositis treated with azathioprine and corticosteroids. Three months after the combined treatment was initiated, the patient developed right thoracic herpes zoster, agranulocytosis and liver enlargement with signs of portal hypertension. Needle biopsy of the liver revealed peliosis. Azathioprine was withdrawn. The clinical and laboratory abnormalities disappeared progressively. The main causes of peliosis hepatis are considered. Up to now, azathioprine had been held responsible for peliosis hepatis only in renal transplant recipients.

[Respiratory manifestations of hemorrhagic rectocolitis].

The spectrum of respiratory diseases associated with ulcerative colitis. The respiratory diseases associated with ulcerative colitis have recently been recognized, and principally affect the bronchi. Both chronic bronchitis and bronchiectasis may develop after many years, some of the patients having already undergone colectomy. Chronic bronchitis is characterized by cough and chronic mucopurulent sputum, and these symptoms may be exacerbated during acute flare-ups of ulcerative colitis. The bronchial lesions are inflammatory and can be reversed by corticosteroid therapy. Bronchiectasis produces similar symptoms, but has distinctive radiological features. Corticosteroids may sometimes reduce the symptoms, but they have no effect on the bronchial lesions. Salicylazosulfapyridine might be responsible for hypersensitivity lung diseases with eosinophilia, but the drug does not seem to be involved in the genesis of these bronchial manifestations. There have been occasional reports of other respiratory diseases associated with ulcerative colitis, including obliterative bronchiolitis, isolated and asymptomatic airflow obstruction, inflammatory tracheal stenosis, pulmonary vasculitis, pleurisy and pleuropericarditis, chronic pneumonia and interstitial fibrosis which may be diffuse or localized to the apices.

[Interstitial pneumopathies: criteria of drug side-effects. Results of consensus meetings].

Since 1984, the use of the official method for determining the responsibility of drugs in side-effects has been compulsory in France. This method offers, but does not define, different qualificatives for chronological and semeiological criteria. Consensus workshops have been set up to define the undesirable side-effects themselves and the different qualificatives in each of the principal fields of pathology. As regards drug-induced interstitial pneumonia, chest specialists from university hospitals, members of the national system of pharmacovigilance and representatives of the Roussel-Uclaf central department of pharmaco-vigilance have determined: the limits of time elapsed between the beginning and end of drug administration and the occurrence of the adverse reaction; how to interpret various courses of the side-effect with and without temporary discontinuation of the drug, and how to interpret a possible readministration. A list of investigations aimed at excluding the main possible causes of interstitial pneumonia has been drawn up.

[Drug-induced respiratory complications. Study of 27 cases].

Over 8 1/2 years, we observed 27 patients with drug-induced respiratory disease (DIRD). The inducer drugs were mainly those used in cardiology (9 patients, of whom 8 had amiodarone pneumonitis), in oncology (8 patients), in rheumatology (4 patients; 3 from d-penicillamine and 1 from gold), and in neurology (4 cases from ergoline derivatives). The main pattern of DIRD was a diffuse interstitial lung disease having either a rapid, a slowly progressive or a chronic course. Only the two former patterns offered clearing following withdrawal of the drug. Severe bronchiolitis obliterans from d-penicillamine (2 cases) and pulmonary eosinophilia (2 cases) was also observed. The onset of DIRD occurred earlier, i.e. following shorter periods of drug administration (months), in the acute interstitial lung disease variant, while it occurred after years of drug exposure in subacute and chronic forms. In contrast to other reports, bronchoalveolar lavage lymphocytosis was not a prominent feature in amiodarone pneumonitis. The outcome was favourable in 16 patients; deaths was encountered during the florid phase of DIRD in 3; incapacitating sequelae were noted in 6 patients, leading to subsequent death in 2; the underlying disease accounted for 7 additional deaths. Therefore, DIRD are relatively common, develop often in patients with severe underlying conditions, and interstitial pneumonitis is their pattern of predilection. Amiodarone emerges as a common inducer, and accounted for more cases than all chemotherapeutic agents grouped together in our series.

[Pericarditis in bird raiser's disease (author's transl)].

The authors report the case of a 53 years-old male who was presenting signs of a chronic interstitial pneumonitis. A pericarditis was found and the ECG abnormalities first disappeared, then reappeared with new exposure to birds, before making the diagnosis of bird raiser's lung on the history and the immunologic findings. The possibility of pericardial involvement during bird raiser's lung or farmer's lung is found in 4 previously reported cases.
