The clinical efficacy and toleration of amikacin was investigated in 22 patients most of whom had chronic urinary tract infections that had already been treated unsuccessfully on several occasions with other antibiotics. Amikacin was administered i.m. in a dosage of 7.5 mg per kg twice daily for an average of 11.4 days. This new aminoglycoside antibiotic proved highly effective in the treatment of chronic pyelonephritis and cystitis, as well as in septicaemia caused by gentamicin-resistant Pseudomonas. The pharmacokinetic studies did not show any retention after a ten day treatment with amikacin. Thorough nephrologic and otologic investigations for side-effects did not show any permanent nephrotoxic or ototoxic damage or delayed damage. The results were compared with the clinical and experimental data in the literature and with the results of experimental studies which have not yet been published.

The antibody-coated bacteria (ACB) immunofluorescence test has emerged as the preferred noninvasive technique to distinguish reliably between pyelonephritis and cystitis. Investigators have recently correlated a positive test with chronic bacterial prostatitis and cystitis complicating a bladder tumor or stone. We present data that appear to prove that acute bacterial epididymitis associated with bacteriuria can also evoke a positive ACB determination.

Using the fluorescent antibody test, the presence of antibody-coated bacteria in 10 out of 17 urine sediment samples from cattle infected with Corynebacterium renale is described. These antibodies were mainly of the immunoglobulin class IgG, and to a lesser extent IgA. This finding is characteristic for infections of the upper urinary tract (pyelonephritis). In seven samples no antibody coating of the bacterial surface was detected. In these cases an infection of the lower urinary tract (cystitis) is suggested.

It has been shown that some, but not all, Escherichia coli strains isolated from urine adhere, in vitro, to the surface of uroepithelial or vaginal cells. In the present study, 212 strains, isolated from urine of 212 infected patients, were tested for adhesion by using an in vitro human cell line assay. A variable degree of attachment to the cell monolayer was detected in these strains. From patients with cystitis, only 19 (9.7%) of the 195 strains examined were adherent, whereas 5 (29.4%) of the 17 pyelonephritis strains had similar properties (P less than 0.05). To investigate the incidence of adhesion in the clinical manifestations of urinary tract infection, a sample of patients was picked at random from those with cystitis. During cystitis caused by adhesive bacteria, patients suffer more often from macroscopic hematuria than from dysuria, frequency, or recurrency (P less than 0.05). This study shows that E. coli strains isolated from urine samples possess a strikingly difference in capacity to adhere to a human cell line surface as demonstrated previously with uroepithelial or vaginal cells. Moreover, according to these data, the adhesion of E. coli may be considered as a virulent factor and would play a part in the infection of the urinary tract in humans.

New methods to localize the source of bacteriuria were evaluated in monkeys with experimental urinary tract infection. A high level of diagnostic accuracy was obtained with the combined study of antibody-coated urinary bacteria by immunofluorescence, 131I hippuran scintiphotos in the hydropenic state and 67gallium citrate scintiphotos. Unique patterns were found, which differentiate cystitis, ureteritis, pyelonephritis and renal or perinephric abscesses.

Sterilized and unsterilized catheters were passed into the urinary bladders of 9 clinically normal adult male dogs once daily for 5 consecutive days, and the dogs were examined for up to 30 days to determine whether urinary tract infections developed. Two dogs that were catheterized with clean unsterilized catheters (1 clinically normal dog and 1 dog given immunosuppressant drugs) developed persistent cystitis and pyelonephritis due to infection with Proteus sp. One dog given immunosuppressant drugs developed a mixed bacterial infection (Proteus sp and Escherichia coli) that resolved without treatment between 22 and 30 days later.

Two young ponies had the prescrotal portion of their penises accidentally amputated during castration. They both developed ascending urinary tract infections over the next 4 weeks. One pony had a necrotising cystitis and pyelonephritis, the other improved markedly after a urethrostomy had been performed but was destroyed several months later.

A clinical investigation was carried out on a new penicillin derivative, bacampicillin with the following results. (1) Clinical effect--Bacampicillin was administered orally to 18 patients with acute simple cystitis, acute simple pyelonephritis, chronic prostatitis and acute gonorrhoic urethritis. Daily doses ranged from 750 mg to 1,000 mg. The administration continued for 4 to 14 days. Clinical effect was excellent in 10 patients and good in 5 patients. (2) Side effect--Side effects were noticed in 4 patients, one was allergic eruption and other 3 were gastralgia. In a patient the drug was discontinued to administer.

The test for antibody-coated bacteria in urine for the diagnosis of the anatomical level of urinary tract infections was evaluated in children with UTI. The ability of the test to differentiate between an upper and lower infection is influenced by the antiglobulin preparation used, since too sensitive an antiglobulin probably detects nonspecifically bound antibodies. Staphylococcal protein A seems to be well suited for use as an antiglobulin in this test. Using staphylococcal protein A all children with X-ray findings suggesting renal damage had antibody-coated bacteria in the urine, however, nine infants and 5 children and clinical symptoms of pyelonephritis had a negative test. Of 28 children with clinical symptoms of cystitis only one had a positive test. Of 50 children with asymptomatic bacteriuria 9 had antibody-coated bacteria in the urine; 41 had not. The findings indicate that the method might be useful in establishing the anatomical level of urinary tract infection and might also be useful for screening children with asymptomatic bacteriuria who risk developing kidney infections.

Eighty patients with urinary tract infections were randomly divided into two equal groups; one group received tobramycin, and the other received gentamicin. The daily dose of antibiotic for each group was 3 mg/kg. Mean levels in serum were 4.5 and 4.7 mug/ml, respectively, 1 hr after an intramuscular injection, and the mean duration of therapy was 6.5 days. Mean ages and sex ratios were similar in the two groups. Essentially equal numbers of patients with pyelonephritis and cystitis were assigned randomly to each group. Eradication of infection was similar in patients in the two treatment groups, and there was not a significant number of relapses or reinfections in either group. Renal function was abnormal in seven patients treated with gentamicin and in two patients treated with tobramycin. One patient in the gentamicin group developed a skin eruption. Our data suggest that tobramycin is as effective as gentamicin in the treatment of acute urinary tract infection and may be less nephrotoxic at similar doses.
