Lupus anticoagulant and leg ulcers associated with ankylosing spondylitis.

We describe a 60-year-old man with ankylosing spondylitis (AS), hospitalized for leg ulcers. Laboratory investigations revealed the presence of the lupus anticoagulant. We found no such an association by a computer assisted search of the literature published from 1975 to 1989. The relationship between the AS, the lupus anticoagulant and leg ulcers is discussed.

[Esophagitis in progressive systemic scleroderma. Prevalence and risk factors in forty-six patients].

Forty-six patients with progressive systemic sclerosis (37 women and 9 men) were successively evaluated by endoscopy, manometry, and esophageal pH monitoring. Fourteen patients (30.4 percent) had erosive esophagitis. Twenty-four patients were symptomatic; nineteen patients complained of dysplagia. Erosive esophagitis was significantly more frequent in symptomatic patients than in asymptomatic patients (50.0 percent vs 9 percent, P less than 0.01) and especially in patients complaining of dysphagia (57.9 percent vs 11.1 percent, P less than 0.01). Erosive esophagitis was not correlated with symptoms of gastroesophageal reflux. Abnormal esophageal motility was found in 34 patients (73.9 percent). Occurrence of erosive esophagitis was not linked with esophageal dysmotility. In patients with erosive esophagitis lower esophageal sphincter pressures were significantly lower than those in patients without erosive esophagitis. Twenty-four hr-pH monitoring showed pathological gastroesophageal reflux in 20 patients (43.5 percent). Erosive esophagitis was more frequent in patients with pathological gastroesophageal reflux than in patients with normal gastroesophageal reflux (50.0 percent vs 15.4 percent, P less than 0.02) especially in patients with pathological supine nighttime gastroesophageal reflux (61.5 percent vs 18.2 percent, P less than 0.01). Our data suggest that symptoms, dysphagia, diminished lower esophageal sphincter pressures, and pathologic nighttime gastroesophageal reflux are reliable predictors of the presence of erosive esophagitis in patients with progressive systemic sclerosis.

[Erysipelas: epidemiological, clinical and therapeutic data (111 cases)].

A retrospective study of 111 patients admitted to the Dermatology department of the Bichat hospital, Paris, between 1981 and 1988 for treatment of erysipelas revealed the following data: 1. Erysipelas was located on the lower limbs in 88.3 p. 100 of the cases and on the face in only 9.8 p. 100. 2. Facilitating and/or aggravating factors were: portal of entry in 75 p. 100 of the cases; impairment of venous and lymphatic circulations (41 p. 100); diabetes mellitus (13.5 p. 100); alcoholism and its socio-economic consequences (29 p. 100); unnecessary prescription of anti-inflammatory agents (11 p. 100). 3. Insufficient consideration was given to the clinical diagnosis: in 7.2 p. 100 of the patients erysipelas was diagnosed either after failure of heparin therapy or because phlebography was normal; some clinical features, notably bullae (30 p. 100) or purpura on the lower limbs (13 p. 100), confused the physicians. Delayed treatment was the main cause of local complications, such as abscess (4 cases) or focal cutaneous necrosis (4 cases). Erysipelas was recurrent in 23.5 p. 100 of the patients. 4. Bacteriological data in this series were insufficient to establish percentages of responsible organisms. However, penicillin G in mean doses of 12 million units per day administered intravenously for 5.5 days, then intramuscularly for 10 days was effective as first-line treatment in 80 p. 100 of the cases. Penicillin therapy may fail in patients with insulin-dependent diabetes or belated treatment with complications. No thromboembolic complication was observed (89 p. 100 of patients with lower limb erysipelas had received anticoagulants). There was only one death due to a severe underlying condition.
