Management of bacteriuria in pregnancy.

Bacteriuria of pregnancy is a common condition which, although usually asymptomatic, may give rise to potentially serious sequelae. All pregnant women should therefore be screened for the presence of bacteriuria, which if detected should be treated with an antimicrobial agent believed to be safe for use in pregnancy. Appropriate antimicrobial drugs include penicillins, cephalosporins and nitrofurantoin. Nalidixic acid, aminoglycosides and sulphonamides may be used under certain circumstances and with some precautions. Tetracyclines, trimethoprim and co-trimoxazole (trimethoprim-sulphamethoxazole) should be avoided. There is some evidence that short-course therapy in pregnant women is less effective than longer courses, and we continue to recommend a 7-day course. Follow-up after completing a treatment course is an essential part of managing bacteriuria of pregnancy.

The isolation of Moellerella wisconsensis from stool samples in the U.K.

Three strains of Moellerella wisconsensis were isolated from a total of 400 stool specimens screened for this organism by means of a new selective medium developed in this laboratory. This is the first report of the isolation of this organism in the U.K. The exact role of M. wisconsensis in causing diarrhoea remains to be elucidated.

Comparative study of amoxicillin-clavulanic acid and cephalexin in the treatment of bacteriuria during pregnancy.

A comparative clinical trial of amoxicillin-clavulanic acid and cephalexin was carried out in 80 women with bacteriuria of pregnancy. Treatment was randomly allocated and consisted of either one tablet of amoxicillin plus clavulanic acid (250 and 125 mg, respectively) three times daily or cephalexin (250 mg) three times daily for 7 days. Overall bacteriological cure rates at 2 weeks were 77% in the amoxicillin-clavulanic acid group and 74% in the cephalexin group. At 6 weeks the respective rates were 76 and 60%. Twenty-five episodes of infection were with ampicillin-resistant strains; cure rates were 82% (2 weeks) and 80% (6 weeks) in the amoxicillin-clavulanic acid group and 85 and 64%, respectively, in the cephalexin group. Differences in cure rates were not statistically significant. No significant difference in the rate of side effects was found. In particular, no toxicity to the fetus was seen which could be ascribed to either drug. Amoxicillin-clavulanic acid would appear to be a safe and effective treatment for bacteriuria of pregnancy.

Treatment of acute urinary infection by norfloxacin or nalidixic acid/citrate: a multi-centre comparative study.

The efficacy, tolerability and side effects of a 3-day treatment for acute urinary infection in general practice with norfloxacin (400 mg 12 hourly) or nalidixic acid/citrate (1 sachet 8 hourly) were compared in a randomized study. Patient groups had similar demography, symptomatology and initial infecting bacteria. Of the evaluable 55 patients in each treatment group with initial bacteriuria, 53 (96%) had no bacteriuria at immediate follow-up after treatment with norfloxacin and 45 (82%) with nalidixic acid/citrate. The corresponding rates at late follow-up were 40/45 (89%) and 29/43 (67%) (P less than 0.05). Among the bacteriuric patients a significantly greater proportion were recorded as having cured and improved symptoms. The tolerability of norfloxacin seemed to be better than that of nalidixic acid/citrate.

Ceftazidime therapy for serious infections.

Thirty-two episodes of severe infection in 23 patients were treated with parenteral ceftazidime: 96% of the infections were cured or improved. Of 15 chest infections in cystic fibrosis patients, 14 responded satisfactorily to treatment, including 9 cases where Pseudomonas aeruginosa and 7 cases where Staphylococcus aureus was a pathogen. All seven cases of peritonitis in peritoneal dialysis patients were cured or improved. Other infections that responded to treatment were urinary tract infections (3), septicaemias (2), wound infections (2), acute bronchitis (2) and cholangitis (1). Ceftazidime was shown to produce good blood and peritoneal dialysis fluid levels and to penetrate into sputum. Adverse effects were few and not serious.

Peritonitis in continuous ambulatory peritoneal dialysis. Laboratory and clinical studies.

During a three year period, 1979-81, 82 patients were treated by continuous ambulatory peritoneal dialysis (CAPD). The incidence of peritonitis was reduced significantly during the three years from one episode per 20 patient-weeks to one episode every 37 patient-weeks. 83% of the 136 episodes of peritonitis were treated successfully by antibiotic therapy alone. 62% of the total episodes were managed successfully with intraperitoneal cefuroxime. in 13 (16%) patients, CAPD failed because of peritonitis. Hospital admission for peritonitis has been reduced to a mean of 4.3 days per patient per year of CAPD. Fron January to September, 1982, Clostridium-difficile colitis developed in 13 patients. This complication was associated with considerable mortality and morbidity and has prompted a change in antibiotic policy. Patients with peritonitis are now given intraperitoneal netilmicin and intravenous vancomycin. Peritonitis remains the main complication of CAPD, but can be minimised by development of adequate facilities for performing CAPD.

Effect of single-dose prophylactic co-trimoxazole on the incidence of gynaecological postoperative urinary tract infection.

One hundred patients having abdominal hysterectomy for benign conditions were randomized into two groups; 50 received co-trimoxazole by intramuscular injection immediately before operation and a control group of 50 were given no antibacterial cover. Single-dose chemoprophylaxis with co-trimoxazole was effective in reducing the incidence of postoperative urinary tract infection from 35% in the control group to 4% in the treated group.

Simple method for isolation and presumptive identification of Clostridium difficile.

Clostridium difficile can be isolated from stools and presumptively identified by inoculating the stools onto CCCBA and the culture looked at under ultra violet light where the golden-yellow fluorescent colonies show up against a dark background. The colonies are then identified by testing them using the API ZYM system and the results further confirmed by testing the culture for toxin production using the tissue culture technique employing Cl. sordellii antitoxin.

Adverse antibiotic drug interactions.

There is enormous potential for drug interactions in patients who, today, often receive many drugs. Antibiotics are prominent amongst the groups of drugs commonly prescribed. Many interactions take place at the absorption stage. Antacids and antidiarrhoeal preparations, in particular, can delay and reduce the absorption of antibiotics such as tetracyclines and clindamycin, by combining with them in the gastrointestinal tract to form chelates or complexes. Other drugs can affect gastric motility, which in turn often controls the rate at which antibiotics are absorbed. Some broad spectrum antibiotics can alter the bacterial flora of the gut which may be related to malabsorption states. The potentiation of toxic side effects of one drug by another is a common type of interaction. Antibiotics which are implicated in this type of interaction are those which themselves possess some toxicity such as aminoglycosides, some cephalosporins, tetracyclines and colistin. Some of the most important adverse interactions with antibiotics are those which involve other drugs which have a low toxicity/efficacy ratio. These include anticoagulants such as warfarin, anticonvulsants such as phenytoin and phenobarbitone and oral antidiabetic drugs like tolbutamide. Risk of interaction arises when the metabolism of these drugs is inhibited by liver microsomal enzyme inhibitors such as some sulphonamides and chloramphenicol, or is enhanced by enzyme inducers such as rifampicin.

The sensitivity of gentamicin-resistant gram-negative bacilli to cefotaxime, other cephalosporins and aminoglycosides.

The sensitivities of 80 gentamicin-resistant gram-negative bacilli to cefotaxime, cefuroxime, cefoxitin, cefamandole, cefazolin, tobramycin, netilmicin and amikacin were determined. Amikacin was the most active amino-glycoside. However, the percentage sensitivity to cefotaxime of most of the species was higher than, or equal to any of the other antibiotics tested. Cefotaxime was particulary active against Providencia spp., Serratia spp., Klebsiella spp., and Pseudomonas maltophilia, being 16 to 256 times more active than the next best cephalosporin or cephamycin. Clinical trials of cefotaxime are now required.
