To evaluate the diagnostic significance of the demonstration in urine of antibodies to Mycoplasma hominis, 1,000 samples of urine with more than 5 leukocytes per high-power field were serologically investigated by indirect hemagglutination, using glutaraldehyde-fixed erythrocytes coated with M. hominis antigen. The samples were collected from 702 patients. Antibodies were demonstrated in the urine of nine patients, all of whom had signs of acute attack of pyelonephritis. In seven of these patients, characterized by mild or moderate clinical signs and absence of lower urinary tract symptoms, bacterial causes were not observed, whereas M. hominis organisms were isolated from the upper urinary tract in most cases and from the bladder urine in all cases. In two patients, characterized by severe clinical signs and presence of lower urinary tract symptoms, both M. hominis and bacteria were isolated from the upper urinary tract and ballder urine. The demonstration of antibodies to M. hominis in urine is of high diagnostic value as they were only observed in patients in whom M. hominis infection in the upper urinary tract was evident or likely and only in the presence of clinical signs of acute attacks of pyelonephritis.

Mycoplasma hominis was isolated from the upper urinary tract in 7 of 80 patients with acute pyelonephritis and from 0 of 60 patients with noninfectious diseases of the urinary tract, a significant difference. In four cases M. hominis was isolated in pure culture, in one it was isolated together with Ureaplasma urealyticum, and in two it was isolated with bacteria. U. urealyticum was isolated from the upper urinary tract of five patients, all with acute pyelonephritis; this was not significantly different from the control group.

This study was carried out to elucidate by serological examination the etiological significance of mycoplasmas isolated from the upper urinary tract of patients with pyelonephritis. The occurrence of antibodies in patients with acute pyelonephritis, chronic pyelonephritis with or without exacerbation, or noninfectious urinary tract disease was compared by the indirect hemagglutination method. Antibody response was demonstrated significantly more often in patients yielding growth of Mycoplasma hominis from the upper urinary tract than in patients not yielding growth. Antibodies against M. hominis were demonstrated in ureteric and bladder urine from three patients with acute pyelonephritis and from one patient with exacerbation of chronic pyelonephritis. M. hominis was isolated from the upper urinary tract of all four patients. Urine antibodies could not be demonstrated in any other cases. Thus, it seems highly possible that M. hominis may play a role in pyelonephritis of humans. The investigations did not disclose a similar role for Ureaplasma urealyticum.

The authors consider the current state of the problem and personal data on the role of L-forms of bacteria and mycoplasma in human infectious pathology. L-forms of bacteria were isolated from the urine in 10% of the patients suffering from pyelonephritis and mycoplasmae--in over one third of all the patients both with pyelonephritis and with cystites and prostatitis. Some of the isolated strains of mycoplasmae produced a cytopathogenic effect on the cell cultures, whereas the rest caused a latent infection. Drug sensitivity determined to ten antibacterial preparations with a wide range of action differed in strains of the same species. The efficacy of treatment and the prospects of microbiological studies in cases with atypical and latent courses of inflammatory processes of the urogenital organs in discussed.

Bacteriological analysis of urine of 150 patients with chronic pyelonephritis was performed. As a result mycoplasma was isolated from urine of 25 patients. Mycoplasma and Coli bacteria or Proteus were isolated simultaneously from urine of 10 patients. Biochemical properties and sensitivity to antibiotics of 9 isolates were studied. The data provided recommendation of the urine analysis for the presence of mycoplasma.

The effects on the urinary tract after inoculation of Ureaplasma urealyticum into the rat bladder were evaluated and compared to that seen after Mycoplasma hominis, Escherichia coli and Proteus mirabilis inoculation. The inoculation of the urease-producing organisms P. mirabilis and U. urealyticum were associated with the formation of struvite bladder stones and predominantly hyperplastic lesions of the bladder. The P. mirabilis inoculated rats also displayed marked pyelonephritis. A similar but much less pronounced reaction also occurred in the kidneys of some of the U. urealyticum inoculated rats. P. mirabilis could frequently be recultured. In contrast, this was not possible with U. urealyticum, but the organism was detected by scanning electron microscopy 2 weeks after the inoculation. Inoculation of M. hominis was associated with a few mild lesions of the bladder, but inflammatory lesions were not present in the kidneys. The study confirms the potential of Ureaplasma to form struvite stones in rat urinary tract. It also demonstrates that it can induce inflammatory changes in both bladder and kidney of rats without concomitant stone formation.

A number of organisms, including Mycoplasma, group B Streptococcus, Bacteroides, Neisseria gonorrhoeae and Chlamydia trachomatis, have been isolated more frequently from patients in premature labor than from controls. Prophylactic antibiotic treatment in some studies lowered the incidence of prematurity. Silent chorioamnionitis has been noted in 15% of patients in premature labor. Untreated pyelonephritis is clearly associated with premature labor; however, the association of asymptomatic bacteriuria, appropriately treated pyelonephritis and premature labor is less clear. Some microorganisms have been demonstrated to produce phospholipase A2 and possibly prostaglandins, which might be the mechanism for some of the associations between premature labor and bacteria.

From the urine cultures of 1238 patients with renal or suspicious for renal disease mycoplasmas were isolated in 119 (9.6%). In 75 patients the mycoplasmas were typified. In 56 patients M. hominis and in 24 patients Ur. urealyticum were isolated. In 52 patients there were data for pyelonephritis, in 46 patients there was no renal infection. In 21 patents there were mycoplasmas and arterial hypertension without sufficient data for pyelonephritis. In the group of patients with pyelonephritis and arterial hypertension the infection with M. hominis, which is considered pathogenic for the kidneys, prevailed. In 23 patients a mixed flora was isolated and in 19 of them there was pyelonephritis. In 33 patients (27.7%) there were data for pyelonephritis and an independent Mycoplasma infection. Cases with Mycoplasma hominis prevailed. It is isolated in 16 out of 20 typified strains. All isolated mycoplasmas showed high sensitivity to tetracycline and gentamycin. 51 patients were treated by antibiotics. 35 patients were treated with methacycline, 33 of them successfully. 10 patients were treated with other antibiotics. The tetracyclines are recommended for the treatment of Mycoplasma infections.

We investigated the clinical efficiency and safety of ofloxacin, a new fluoroquinolone, for the treatment of various documented bacterial infections in 26 patients (10 females, 16 males) aged 17 to 84 years. Ofloxacin monotherapy was given orally in a dose of 200 mg twice (25) or three times (1) a day. Antibiotic levels and serum bactericidal activity were measured using a microbiological method on the second and sixth days, before and 2 and 6 hours after a single dose. The infectious episode treated was enterocolitis in 7 cases (5 Shigella, 2 Salmonella), Salmonella septicemia in 9 (7 typhoid fevers and 2 Salmonella minor infections), chronic osteoarthritis in 3 (1 E. coli, 2 S. aureus + P. aeruginosa), a soft tissue infection in 3 (2 S. aureus, 1 E. coli), acute pleuropneumonia in 2 (2 Klebsiella pneumoniae), pyelonephritis with bacteremia in 1 (Klebsiella pneumoniae), and pneumococcal pneumonia with septicemia in 1. Mean duration of therapy was ten days for 23 patients (range 7 to 30 days). The three patients with osteoarthritis were treated for 35, 95 and 270 days respectively. 24 patients recovered free of sequelae or germ carriage. Treatment failed in 1 case of chronic osteitis (S. aureus + P. aeruginosa) and in 1 staphylococcal soft tissue infection. No adverse reactions were observed except a slight increase in transaminases in 3 patients. Peak and through serum ofloxacin levels were 3.70 micrograms/ml and 0.95 micrograms/ml respectively on the second day and 3.25 micrograms/ml and 0.80 microgram/ml respectively on the sixth day.(ABSTRACT TRUNCATED AT 250 WORDS)

A study was made of the clinical, x-ray and immunological features of acute pneumonias (AP) developing against a background of chronic pyelonephritis in 28 patients aged 60 and over this age. Routine microbiological inoculation of the sputum as well as noncultural methods (definition of antigen substances and specific antibodies in the blood serum) were employed for etiological deciphering. A modern program of etiological diagnosis ensured the detection of a wide spectrum of agents including viruses, Mycoplasma and Legionella. Pneumococci, streptococci, hemophilic bacteria in the form of monocultures as well as part of associations of microorganisms were shown to be the most frequent agents causing AP. The resistance of 495 strains of pneumococci, streptococci and hemophilic bacteria to antibiotics was considered. A low sensitivity of these cultures to tetracyclines and biseptol was observed. Caramycin and chloramphenicol were recommended for the treatment of AP combined with chronic pyelonephritis.
