Monitoring aminoglycoside use in patients with severely impaired renal function.

Twenty patients with severely impaired renal function, 17 of wnom had recently transplanted kidneys, were treated with aminoglycosides for severe infections acquired in hospital. Serum aminoglycoside concentrations were closely monitored and dosages adjusted individually to obtain peak and trough concentrations that ensured adequate treatment while avoiding toxicity. Causative organisms were susceptible to treatment in 21 out of 26 episodes of infection (81%), and 12 of the 17 patients (71%) in whom organisms were isolated were cured. Nephrotoxicity attributable to aminoglycosides alone was not observed during the 35 courses of treatment. Ototoxicity occurred in only one patient, who had excessively high serum concentrations of amikacin. Serum aminoglycoside concentrations were directly affected by carbenicillin and flucytosine. The concurrent administration of cephradine and cephalexin with gentamicin may have produced nephrotoxicity. We conclude that aminoglycosides, when carefully monitored, are effective and safe in patients with severely impaired renal function.

Pleuropulmonary lung infection by anaerobic bacteria.

Two patients with severe pleuropulmonary infection caused by non-sporing anaerobic bacteria are described. One had an empyema with foul-smelling pus and developed bacteraemia, and the other developed a lung abscess. Both were successfully treated with antibiotics and drainage, chest surgery being avoided. The successful diagnosis and treatment of these patients involved close liaison between clinical and laboratory staff.

The use of a fluorescence typing method in an epidemiological study of Klebsiella infection in a London hospital.

The fluorescent antibody technique was used to investigate an epidemic of Klebsiella infection in a urological ward and to trace the probable source to a contaminated sink in the treatment room. It was also shown that cross infections by particular capsular types were very common within each ward. Certain types of Klebsiella occurred in cut flower water but could not be associated with the types infecting the patients. Antibiotic resistance patterns within one capsular type were found to vary whether the type was from different sources in one patient or from different patients in the same ward. One capsular type was observed to develop resistance to increasing numbers of antibiotics over a 3-year period. This was probably due to the acquisition of R-plasmids. There also appeared to be a relation between capsular type and the site of infection. The frequency of Klebsiella infections in the urological wards dropped significantly after up-grading the treatment room, improving catheter storage and reducing ampicillin use.

Outbreak of necrotising enterocolitis caused by Clostridium butyricum.

12 hospital-born babies had necrotising enterocolitis, of varying severity, within six weeks, 5 of them within ten days. The usually described predisposing causes were absent in most, though no baby was exclusively breast -fed. Evidence of the presence of Clostridium butyricum was found in the blood of 9 out of 10 babies examined. Cl. butyricum is probably a primary, not a secondary invader.

Prophylactic systemic antibiotics in colorectal surgery.

The prophylactic value of gentamicin combined with either lincomycin or metronidazole in 52 patients undergoing colorectal surgery was investigated. The results confirmed the value of this practice. In a control group, the sepsis-rate was 48% with 1 death attributable to sepsis, compared with a sepsis-rate of 4% in the treated group. The combination of gentamicin and lincomycin was effective against sepsis but pseudomembranous colitis developed in 2 of the 14 patients treated with this combination of drugs. Lincomycin was discontinued, and when metronidazole was substituted the results were equally good and there were no toxic side-effects.
