Bleeding secondary to vitamin K deficiency in patients receiving parenteral cephem antibiotics.

Thirteen patients who were treated with cephem antibiotics developed blood coagulation disorders due to vitamin K deficiency. At the time of detection of prolongation of the prothrombin time, cefazolin was being administered in four cases, cefmetazole and latamoxef (moxalactam) in three cases each, and cefoperazone, cefpiramide and ceftazidime in one case each. Bleeding occurred in ten patients, but administration of vitamin K rapidly eliminated the prothrombin time prolongation and the haemorrhagic tendency. To date, we have not detected prothrombin time prolongation or a haemorrhagic tendency with cefotaxime, ceftizoxime, cefotiam, cefoxitin or cefsulodin. Thus, different cephem antibiotics show different effects on the prothrombin time.

Bacteriology of acute obstructive suppurative cholangitis of the aged.

Bacteriological examination was performed on bile from 23 patients with acute obstructive suppurative cholangitis. Of 23 bile cultures, 15 yielded aerobic and anaerobic bacteria and 8 yielded aerobic bacteria only. No specimen grew anaerobic bacteria only. A total of 20 cultures yielded a polymicrobial flora, and 3 cultures grew one single aerobic bacterium. Escherichia coli, Klebsiella sp., enterococci, Bacteroids fragilis, and Clostridium perfringens were the predominant bacterial flora in bile of these patients. Bacteremia was documented in 10 of the 12 patients cultured. All bacteremias involved aerobic bacteria and were polymicrobial in three patients. The frequent presence of anaerobes in bile of patients with acute obstructive suppurative cholangitis suggests that antimicrobial therapy should provide adequate coverage for anaerobic bacteria and enteric organisms.

[Bacteriological and clinical studies on metronidazole in Bacteroides fragilis infections (author's transl)].

The antimicrobial activity of 24 Bacteroides fragilis, 13 Bacteroides thetaiotaomicron and 5 Bacteroides vulgatus, all of which were recent clinical isolates, was determined by the agar dilution technique. These three species had similar susceptibility patterns, but the B. thetaiotaomicron strains were generally less susceptible than the B. fragilis strains. Clindamycin was very active against 81% of the Bacteroides strains at 3.1 mcg/ml of less while 21% of the Bacteroides strains had MICs of 100 mcg/ml or above. Metronidazole was active against all Bacteroides strains at 1.6 mcg/ml or less. The patients with decubitus ulcers and B. fragilis septicemia, who responded satisfactorily to the combination of metronidazole and tobramycin, were presented.

Anaerobic bacteria in biliary disease in elderly patients.

Gallbladder bile from 52 elderly subjects who had undergone biliary tract surgery was examined for the presence of bacteria. Twelve patients had sterile bile, 18 specimens of bile yielded anaerobes as well as aerobes, and 22 yielded aerobic bacteria only. Escherichia coli was the most commonly isolated organism (30 strains). Bacteroides fragilis was the most frequently encountered anaerobic bacterium and was found in 15 patients. The Klebsiella-Enterobacter group was the second most commonly isolated group and B. fragilis was third. Clostridium perfringens was recovered in 10 specimens of bile. Anaerobic bacteria were recovered more frequently in patients with ductal obstruction. The relatively frequent isolation of anaerobes, especially of B. fragilis, in this study may be related to the anaerobic techniques used, to the age of the patients, and to the high incidence of pigment stones among the subjects.

Biliary tract infection with anaerobes and the presence of free bile acids in bile.

Gallbladder bile from 24 patients (five with anaerobic biliary tract infection, 10 with aerobic biliary tract infection, and nine without biliary tract infection) was examined by thin-layer chromatography (TLC) for the presence of free bile acids. All five patients with an anaerobic biliary tract infection had small amounts of free bile acids in gallbladder bile. Seven of 10 patients with aerobic biliary tract infection and nine patients with sterile bile had no detectable free bile acids. Minute amounts of free bile acids were detectable on TLC in bile of three patients with aerobic infections. Calcium bilirubinate stones were more common in patients with free bile acids in bile.
