In a study of 718 women referred for specialist investigation for recurrent urinary tract infections, 250 (34.8%, P less than 0.01) were non-secretors. The proportion of non-secretors among the women with renal scars (42.6%) was higher than that found for women with no evidence of renal scars (36.6%). Among 29 patients in whom symptoms began in childhood or adolescence, 51.7% were non-secretors. The proportion of non-secretors among individuals with renal scars in this study (42.6%) and that reported in the accompanying paper for Swedish children (40%) suggests that non-secretion might influence the pathogenic sequelae of these infections. Possible host-parasite interactions underlying the increased proportion of non-secretors among women with recurrent urinary tract infections and those leading to development of renal scars are discussed. 相似文献

OBJECTIVE--To compare the outcome of pregnancy in women with and without renal scarring after childhood urinary infections with that in unmatched controls. DESIGN--Retrospective study of pregnancies in women prospectively followed up from their first recognised urinary infection. SETTING--Tertiary referral centre in Gothenburg. SUBJECTS--111 Women attending an outpatient clinic for women with urinary infection during 1975-83, of whom 41 (65 pregnancies) were studied (19 women with renal scarring (32), 22 without scarring (33)), and 65 controls (65) randomly selected and matched for parity, age, smoking habits, and date of delivery. MAIN OUTCOME MEASURES--Urinary infections and complications in pregnancy. RESULTS--The incidence of bacteriuria during first pregnancies was significantly greater in women with (9, 47%) and without (6, 27%) renal scarring after childhood urinary infection than in controls (1, 2%) (p less than 0.001, 0.01 respectively). Symptomatic infections were seen only among women with a history of urinary infection: four women with renal scarring (three of whom had vesicoureteric reflux) developed pyelonephritis and three cystitis, and one woman without scarring developed pyelonephritis. Mean blood pressure was higher among women with severe renal scarring than controls (4/11 v 3/44; p less than 0.05) before and during pregnancy. There was no significant difference in the incidence of pre-eclampsia, operative delivery, prematurity, or birth weight. CONCLUSIONS--Women with a history of previous urinary infections had a high incidence of bacteriuria during pregnancy, and those with renal scarring and persistent reflux were prone to develop acute pyelonephritis. The risk of serious complications in pregnancy, however, was not increased in women with severe renal scarring, possibly owing to their continuous clinical supervision. 相似文献

The pathogenesis of recurrent urinary tract infections (UTIs) in preschool children with anatomically correct urinary tract (UT) is rather obscure. In girls, the bladder wall changes of cystitis cystica (CC) may be per se responsible for UTIs recurrence. During the 20-year period, 127 preschool children (125 girls; median age: 6.1 years) with CC, in whom UT anomalies were excluded, were diagnosed. The mean duration of UTIs symptoms prior to diagnosis was 3.31 +/- 2.51 years. Cystoscopical findings were labelled as mild, moderate and severe in 22.8%, 39.4% and 37.8% of patients, respectively. Following the confirmation of CC, long-term chemoprophylaxis with sulfamethoxazole-trimethoprim/nitrofurantoin was administered. A one year UTI-free period after chemoprophylaxis discontinuation was defined as therapeutic success. With 2.5 years median duration of regular chemoprophylaxis this goal was achieved in 58 children mainly with mild/ moderate CC. Thirty children from "improved/unchanged" group taking regular prophylaxis had significant reduction of UTIs ("improved"). Only 12 children belonging to the same group taking regular prophylaxis and all children with irregular prophylaxis had approximately the same number of UTIs as before treatment ("unchanged"). The "improved/unchanged" outcomes were predominantly found in children with severe form of CC. Although urodynamic disturbances detected in more than 50% of patients in whom urodynamics was performed were not found influential on the disease outcome, they could be responsible for its development. The results of our study suggest that regular and long-lasting chemoprophylaxis remains a basis for successful treatment for majority of patients with CC, even those with severe forms. If not treated properly with chemoprophylactic agents and without fair compliance in taking drugs, the disease is prone to recurrent UTIs. 相似文献

Efficiency of ceftriaxone (Rocephin Hoffman Laroche) was assessed in 16 children aged between 3 and 14 years and in 4 adults aged between 17 and 70 years with severe infections of the urinary and respiratory tracts caused by E. coli. S. pneumoniae, P. aeruginosa, P. mirabilis or enterococci. Pyelonephritis as a sole pathology was diagnosed in 10 patients whereas in further 8 patients it complicated other diseases (nephrotic syndrome, hepatitis, cholangitis, leukemia). Pneumonia complicated nephritis leukemia or lymphoma in 8 children. Peritonitis was diagnosed in 1 adult patient. Ceftriaxone was given in a single daily dose of 50 mg/kg to all children and 2.0 g to adult patients for 7-10 days. No adverse reactions were noted. Clinical improvement was achieved in all treated patients. Cultures became negative in 17 cases after the treatment. Significant bacteremia caused by P. aeruginosa persisted in 2 patients and by E. coli in 1 patient. No toxic effects on liver, renal, pancreatic and bone marrow functioning were seen. Ceftriaxone may be safely and efficiently used for the treatment of the urinary and respiratory infections. 相似文献

The purpose of this review is to analyze literature concerning the diagnosis, prevention, and management of catheter-associated urinary tract infection (CAUTI) occurring in patients hospitalized in the intensive care unit (ICU). Analysis was performed from personal and "Pubmed" data, crossing the following keywords: "urinary tract infection", "catheter', and "intensive care unit". Few clinical trials including ICU patients were found despite the abundance of expert opinions. There is no consensus on the use of urinary reagent tests for diagnosis. The prevention of CAUTI in ICU patients does not require expensive devices. Neither complex closed drainage systems nor silver-coated urinary catheters have demonstrated efficacy in comparative randomized clinical trials. Bladder irrigation should not be used, except when an obstruction of the catheter is highly likely. The administration of prophylactic antimicrobial therapy, although effective in reducing the incidence of urinary bacteria, cannot be recommended in ICU patients. The management of CAUTI in ICU patients has not been evaluated in clinical trials. The level of evidence provided in this field is weak, and underlines the need for randomized studies to improve management of patients. 相似文献

BACKGROUND: In a population‐based case‐control study, we investigated the association between congenital cardiovascular malformations (CVMs) and maternal urinary tract infections (UTIs). METHODS: Within the National Birth Defects Prevention Study, 3,690 women who had singleton livebirths with nonsyndromic CVMs, and 4,760 women who had infants without birth defects were identified. Affected infants had: conotruncal, septal, anomalous pulmonary venous return, atrioventricular septal defects, or left‐ or right‐sided obstructive heart defects. Mothers had a UTI if they reported having at least one infection during the first trimester. Adjusted ORs and 95% CIs were computed to determine the association between CVMs and UTIs. Stratified analyses were conducted to investigate if sulfonamide use and/or fever modified the effect between CVMs and UTIs. RESULTS: Women who had offspring with either left ventricular outflow tract obstructive defects or atrioventricular septal defects were more likely than controls to report a UTI. These associations remained among women who did not have fever or used sulfonamides. Maternal use of sulfonamides during the UTI did not appear to modify the relationship between CVM subtypes and maternal UTIs. CONCLUSIONS: In the National Birth Defects Prevention Study there was little evidence to support an association between CVMs and UTIs during the first trimester of pregnancy. Associations between left ventricular outflow tract obstructive defects and maternal UTI as well as between atrioventricular septal defects and maternal UTI were found. Our findings, while not conclusive, suggest that the possible association between maternal UTI and CVMs should be investigated further.
