In 138 adults with monomicrobial E. coli urinary tract infections, IgG coated bacteriuria (ACB) are found in 9/10 acute
pyelonephritis
, 21/24 chronic
pyelonephritis
, 2/5 acute prostatitis, and in only 6/99 lower
UTI
. These urinary antibodies are synthetised localy because IgA-S are found in 75%, in the kidney because humoral IgG antibodies are detected in only 40% of the ACB + patients. O6, O18, O22, O75, are the four most frequent O antigens (47,5%) and no difference were found in the distribution of O serotypes according to ACB production or clinical signs. But rough strains are significantly more frequent in
pyelonephritis
, suggesting a modification of the bacterial wall. The use of ACB test and O serotyping allows a better follow-up of patients, but relapses with ACB- and reinfection with ACB+ show the complexity of the relation host-E. coli.

Girls with various forms of urinary tract infections and a reference material were analyzed for autoantibodies in serum to the Tamm-Horsfall glycoprotein. Such antibodies could be detected in all sera analyzed. In the control subjects cord blood contained very low IgA and IgM anti-TH, which increased significantly up to the age of 8 months. The IgG anti-TH levels in cord blood correlated with maternal levels. After the age of 2 months the IgG anti-TH followed the anti-TH levels of the other immunoglobulin classes. Among the infants aged 2 to 7 months with acute
UTI
, no anti-TH increases were found. In girls more than one year of age with acute nonobstructive
UTI
, IgG and IgA anti-TH levels were significantly higher in those with acute
pyelonephritis
and reflux, with or without parenchymal reduction, than in those with acute
pyelonephritis
and normal radiologic findings. The latter group had significantly higher levels of IgG and IgA but not IgM anti-TH than did those with acute cystitits. In contrast, girls with renal parenchymal reduction but no signs of infection at the time of testing had significantly depressed anti-TH levels compared to control values.

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.

The immunofluorescente technique detecting antibody-coated bacteria for diagnosis of site of
UTI
has been applied to 52 urine samples coming from : 11 patients with clinical diagnosis of pylonephritis, 21 infections of the lower urinary tract, 8 asymptomatic bacteriurias and 2 samples of urine obtained directly by pyelocentesis. The technique confirmed to be specific and sensible: strongly fluorescent germs were observed only in samples coming from
pyelonephritis
or urine from pyelocentesis. Repeatedly, from single samples were isolated more bacterial strains; only one of them was present in significant quantity. The some observation has been made also in 5 patients clinically affected with P.N., where 2 strains were isolated from each sample. In only one sample both strains were fluorescent, white in the remaining 4 samples the strain present in insignificative quantity was fluorescent. These observations, rather than a double localization (pyelo-renal and lower urinary tract) with different aetiologic agents, were interpreted to be the outcome of repeated antibiotic treatments. It is possible that they could have reduced the fluorescent "bacterial load" of the pyelo-renal region under significant number, simultaneously facilitating the emergence of superinfecting germs at the level of the lower urinary tract. We discuss the therapeutic involvements for a proper antibiotic treatment and the usefulness of flanking the test at the quantitative urine culture.

Clinical usefulness of a newly developed assay kit for ACB (SD-8828) which detects urinary bacteria coating IgG was evaluated and compared to the enzyme antibody plate method. A total of 48 patients including 20 patients with acute simple cystitis and 28 patients with acute or chronic
pyelonephritis
, who were shown to have pyuria of at least 5 cells/HPF, bacteriuria of at least 10(4) CFU/ml were enrolled in this study. By enzyme antibody method. ABC was positive in 92.9% of patients with upper urinary tract infection and negative in 100% of patients with lower
UTI
, this difference being statistically significant (p < 0.02). By SD-8828, 85% of positive coincidence rate and 100% of negative coincidence rate, compared to the enzyme antibody technique, was obtained. The overall coincidence rate was high (91.7%). This SD-8828, a new simple assay for ACB, which detects IgG alternating the plate method, may be used as a convenient method in clinical practice.

We clinically evaluated the usefulness of a new oral antimicrobial agent, TFLX, in the field of urology. The dose administered was 150 mg t.i.d and the duration of administration was 3 days. The clinical effect was evaluated according to the criteria of the Japanese
UTI
committee. The clinical response obtained on 164 female patients with acute simple cystitis was excellent in 118, moderate in 44 and poor in 2 patients. The efficacy rate was 98.78%. The clinical response obtained on 4 male patients with acute simple cystitis was excellent in 2 and moderate in 2 patients. The efficacy rate was 100%. The clinical response obtained on 3 female patients with simple
pyelonephritis
was excellent in 2 and moderate in 1 patient. The efficacy rate was 100%. The clinical response obtained on one patient with non-gonococcal urethritis was excellent by doctor's evaluation. The clinical response obtained on 7 patients with complicated
UTI
was excellent in 3 and moderate in 4 patients. The efficacy rate was 100%. Three patients complained of stomach distress or malaise and 2 patients developed rash. No abnormal laboratory data were observed. Thus, TFLX appears to be safe and suitable for use in the field of urology.

A basic and clinical study was made on the significance of stagnancy of urinary flow as a factor causing urinary tract infections. A bacterial solution was inoculated into the bladder of untreated and diabetic mice with model ascending
pyelonephritis
. The longer the external urethral opening was clamped, the lower became the value of ID50, thus showing infection easily caused by urinary stagnancy in the bladder. Patients who had
UTI
within 6 months after prostatic operation were divided into two groups, one with residual urine and the other without residual urine. Then, the type of the causative organism, and the severity of pyuria and bacteriuria were determined. In the former, there were slightly more patients with infection caused by plural bacteria. However, no other differences were observed. The administration of cephem antibiotics revealed no differences in effectiveness between the two groups. In conclusion, stagnancy of urinary flow has been considered a factor easily causing infection. However, so far as residual urine is concerned, it is not an intractable factor in treatment.

The maximal urine concentration capacity was studied in patients with acute
pyelonephritis
and in patients with clinically diagnosed acute cystitis. In the former group renal concentration ability was reduced in 16 of 22 patients and improved in all but two patients. Among patients with symptoms of acute cystitis 6 of 22 had a concentration capacity below 2 SD of normal values. Several of these patients had raised acute phase proteins and increased their urine osmolality at follow-up indicating that cases of acute
pyelonephritis
could have been included. It is concluded that the wide overlap between the groups makes the maximal urinary concentration capacity a method of limited value for level diagnosis in acute
UTI
infection. The test should be reserved for follow-up to reveal permanent renal damage.

Recent retrospective surveys have supported previous investigations in demonstrating the incidence of
UTI
during infancy; 0.3% to 1.2% of infants develop symptomatic
UTI
during the first year of life. Boys are more commonly infected during the first 3 months of life. After the first year, symptomatic
UTI
is much more frequent among girls. Similarly, asymptomatic bacteriuria is more frequently detected in boys than in girls during the first 12 months of life. Thereafter, the incidence decreases markedly in boys but increases in girls. Recent investigations indicate that lack of circumcision is a risk factor for
UTI
among male infants. Recurrent UTI is common and frequently asymptomatic. The most important microbiologic factor that is associated with E. coli causing acute
pyelonephritis
is adherence mediated by P fimbriae. Other factors, such as capsule, lipopolysaccharide, aerobactin production, and serum resistance, also determine the invasiveness of E. coli. Vesicoureteral reflux appears to be an important host factor predisposing to
UTI
. Microbiologic and host factors that are determinants of renal scarring are under investigation.

Acute uncomplicated
UTI
is one of the most common problems for which young women seek medical attention, and it accounts for considerable morbidity and health care costs. Acute cystitis is a superficial infection of the bladder mucosa, whereas
pyelonephritis
involves tissue invasion of the upper urinary tract. Localization tests suggest that as many as one third of episodes of acute cystitis are associated with silent upper tract involvement. Acute cystitis or
pyelonephritis
in the adult patient should be considered uncomplicated if the patient is not pregnant or elderly, if there has been no recent instrumentation or antimicrobial treatment, and if there are no known functional or anatomic abnormalities of the genitourinary tract. Most of these infections are caused by E. coli, which are susceptible to many oral antimicrobials. Because of the superficial nature of cystitis, single-dose and 3-day regimens have gained wide acceptance as the preferred methods of treatment. Review of the published data suggests that a 3-day regimen is more effective than a single-dose regimen for all antimicrobials tested. Regimens with trimethoprim-sulfamethoxazole appear to be more effective than those with beta-lactams, regardless of the duration. Acute pyelonephritis does not necessarily imply a complicated infection. Upper tract infection with highly virulent uropathogens in an otherwise healthy woman may be considered an uncomplicated infection. The optimal treatment duration for acute uncomplicated
pyelonephritis
has not been established, and 14-day regimens are often used. We prefer to use antimicrobials that attain high renal tissue levels, such as trimethoprim-sulfamethoxazole or quinolones, for
pyelonephritis
. Women with frequently recurring infections can be successfully managed by continuous prophylaxis, either daily or thrice-weekly, by postcoital prophylaxis, or, in compliant patients, by early self-administration of single-dose or 3-day therapy as soon as typical symptoms are noted. Our drug of choice for all these regimens is trimethoprim-sulfamethoxazole. Acute uncomplicated cystitis in adult men is very uncommon, but it is occasionally noted in homosexual men who practice insertive and intercourse or in heterosexual men whose partners have vaginal colonization with E. coli.
