Randomized trial comparing ceftriaxone with cefonicid for treatment of spontaneous bacterial peritonitis in cirrhotic patients.

We compared cefonicid (2 g every 12 h) and ceftriaxone (2 g every 24 h) for their efficacy and safety in treating spontaneous bacterial peritonitis in cirrhotic patients in an open randomized clinical trial (30 patients in each group). Clinical, laboratory, and bacteriologic characteristics were similar in both groups. Ceftriaxone-susceptible strains were isolated on 44 occasions (94%), and cefonicid-susceptible strains were isolated on 43 occasions (91.5%). The antibiotic concentration in ascitic fluid/MIC ratio for ceftriaxone was > 100 throughout the dose interval (24 h), while it was lower for cefonicid (between 1 and 18). A total of 100% of patients treated with ceftriaxone, and 94% of those treated with cefonicid were cured of their infections (P was not significant). Hospitalization mortality was 37% in the cefonicid group and 30% in the ceftriaxone group (P was not significant). The time that elapsed between the initiation of treatment and the patient's death was shorter in the cefonicid group patients (5.3 +/- 3.90 days) than in the ceftriaxone group patients (11.8 +/- 9.15 days) (P < 0.05). None of the patients presented with superinfections, and only two patients treated with cefonicid and three patients treated with ceftriaxone developed colonizations with Enterococcus faecalis or Candida albicans. Ceftriaxone and cefonicid are safe and useful agents for treating cirrhotic spontaneous bacterial peritonitis, although the pharmacokinetic characteristics of ceftriaxone seem to be more advantageous than those of cefonicid.

Successful treatment of haemodialysis catheter-related sepsis without catheter removal.

Thirty-six Permcath double-lumen catheters implanted in 36 chronic renal failure patients for haemodialysis treatment were prospectively studied. When catheter-related sepsis was suspected a quantitative blood culture was obtained simultaneously from the catheter and from a peripheral vein. If bacterial colonies in the catheter blood specimen were fourfold greater than identical bacterial colonies in the peripheral blood specimen, the test was considered indicative of catheter sepsis and an empirical antibiotic regimen was begun while the central line remained in situ. Eleven patients suffered 13 episodes of catheter-related sepsis. Staphylococcus epidermidis and Pseudomonas aeruginosa accounted for 77% of the strains isolated. All episodes were successfully treated with vancomycin or ciprofloxacin and yielded negative results on follow-up quantitative blood cultures. Fever subsided within the first 48 h of therapy and no complications occurred. None of these patients required catheter removal for cure of the catheter-related sepsis.

[Pseudolupus induced by a vasculotropic drug (author's transl)]. / Pseudo-lupus induit par un médicament vasculotrope.

The authors report eight cases of women suffering from pseudolupus erythematosus, with positive antimitochondrial antibodies. In six in the past history, a vasculotropic drug, Venocuran or Venopyridum, had been taken. All the patients had had episodes of fever, a pericarditis and/or myocarditis. A pleural effusion was present in six and pulmonary infiltrates in four. The course of the disease was for a limited period (1 to 3 months) in four cases and was chronic in the other four. One patient developed severe mitral incompetence and a cardiomyopathy.
