Incidence of Bacteriuria after Urodynamic Study with or without Antibiotic Prophylaxis in Women with Urinary Incontinence / Incidência de bacteriúria após estudo urodinâmico com ou sem profilaxia antibiótica em mulheres com incontinência urinária

Abstract Introduction The presence of bacteria in urine is called bacteriuria, which may be symptomatic or asymptomatic. The manipulation of the urinary tract during urodynamic study (UDS), which is an invasive procedure, can result in urinary tract infection (UTI). Studies on the use of prophylactic antibiotics for UDSs are contradictory. Some investigators concluded that they were valuable and others did not. The objective of this study is to evaluate the efficacy of antibiotic prophylaxis before UDS. This is a placebo-control randomized double-blind study. Methods Two-hundred and seventeen women affected by urinary incontinence were eligible for this study. All patients had presented negative urine culture previous to the UDS. They were randomized in four groups: group A received placebo, group B received 500 mg of levofloxacin, group C received 80 mg trimethoprim and 400 mg sulfamethoxazole and group D received 100 mg of nitrofurantoin. A urine culture was performed 14 days after the UDS. Results We observed asymptomatic bacteriuria after the UDS in five patients in group A, one in group B, one in group C and one in group D. Only one patient on group A had symptomatic bacteriuria.We didn't observe statistical difference between the groups. When we recategorized the patients in two groups, the incidence of bacteriuria was significantly higher in the placebo group compared with the antibiotic group. Conclusion The conclusion is that antibiotic prophylaxis before the UDS did not reduce the incidence of UTI in women within the target population.

Resumo Introdução A presença de bactéria na urina é denominada bacteriúria, que pode ser sintomática ou assintomática. A manipulação do trato urinário pelo estudo urodinâmico (EUD), que é um procedimento invasivo, pode resultar em infecção do trato urinário (ITU). Os estudos sobre o uso de profilaxia antibiótica para EUD são contraditórios. Alguns investigadores concluíram que era necessário e outros não. O objetivo deste estudo é avaliar a eficácia da antibióticoprofilaxia antes da realização do EUD. Trata-se de um estudo randomizado duplo-cego. Métodos Duzentas e dezessete mulheres comqueixa de incontinência urinária foram recrutadas para este estudo. Todas as pacientes apresentaram urocultura negativa antes do EUD. As pacientes foram randomizadas em quatro grupos: o grupo A recebeu placebo, o grupo B recebeu 500 mg de levofloxacina, o grupo C recebeu 80 mg de trimetoprim e 400 mg de sulfametoxazol e o grupo D recebeu 100 mg de nitrofurantoína. Uma urocultura foi realizada 14 dias após o EUD. Resultados Observamos bacteriúria assintomática após o EUD em cinco pacientes do grupo A, uma no grupo B, uma no grupo C e uma no grupo D. Apenas uma paciente do grupo A apresentou bacteriúria sintomática. Não observamos diferença estatística entre os grupos. Quando recategorizamos as pacientes em dois grupos, a incidência de bacteriúria foi significativamentemaior no grupo placebo emcomparação como grupo antibiótico. Conclusão A conclusão deste estudo é que a antibióticoprofilaxia antes do EUD não reduz a incidência de ITU nesse grupo de mulheres.

Asymptomatic bacteriuria in pregnant women

Asymptomatic bacteriuria could lead to serious complications in pregnant women if untreated. The aim of this study is to evaluate the prevalence of asymptomatic bacteriuria in pregnant women attending antenatal clinic. Antenatal Clinic at King Abdulaziz University hospital, Saudi Arabia. Retrospective Descriptive Cross-Sectional Hospital-Based Study. Nine hundred eighty-seven pregnant women in the second trimester were included in this study, from January 2008 to December 2010. All patients had no signs and symptoms of urinary tract infection [UTI]. Clean catch midstream urine sample was collected from each patient into sterile universal container. The urine samples were examined microscopically and then cultured. Identification of isolates was by standard microbiological technique. Three hundred forty-seven had significant bacteriuria, a prevalence rate of 35.2%. The highest age-specific prevalence was found in the 26-30 years, 113 [11.4%] and the lowest in the 46-48 years, 3 [0.3%]. Streptococcus agalactia was the most predominant organism closely followed by Escherichia coli. The study revealed that the prevalence of asymptomatic bacteriuria in pregnant women was 35.2%. The predominant organisms were Streptococcus agalactia and E. coli. Routine urine cultural test should be performed on all antenatal patients to identify unsuspected infection

Fatores associados à bacteriúria após sondagem vesical na cirurgia ginecológica / Factors associated with bacteriuria after indwelling urethral catheterization in gynecologic surgery

OBJETIVOS: Determinar a frequência e os principais fatores associados à bacteriúria após a sondagem vesical em mulheres submetidas à cirurgia ginecológica eletiva. MÉTODOS: Realizou-se um estudo do tipo coorte em mulheres submetidas à cirurgia ginecológica após sondagem vesical no Instituto de Medicina Integral Prof. Fernando Figueira, no período de janeiro a maio de 2007. As uroculturas foram coletadas até 24 horas após a retirada da sonda e 7/10 dias após a sondagem vesical. A análise estatística bivariada e multivariada foi realizada calculando-se a razão de risco e os seus intervalos de confiança a 95 por cento. RESULTADOS: Foram incluídas no estudo 249 mulheres. A frequência de uroculturas positivas até 24 horas depois da retirada da sonda foi de 23,6 por cento, diminuindo para 11,1 por cento 7/10 dias após a sondagem. Destas, apenas 2,4 por cento eram sintomáticas. Verificou-se menor risco de bacteriúria com 7/10 dias após a sondagem vesical quando a paciente referiu vulvovaginite tratada nos últimos três meses, não permanecendo estatisticamente significativa após a análise multivariada. Não houve associação significativa com idade, escolaridade, número de gestações, paridade, fase da vida reprodutiva, tipo e duração da cirurgia, tipo da anestesia, uso de antibiótico profilático, profissional que colocou a sonda e o tempo de permanência da sonda vesical. CONCLUSÃO: A frequência de bacteriúria foi de 23,6 por cento e 11,1 por cento com 24 horas e 7/10 dias, respectivamente. Não se encontrou associação significativa das variáveis pesquisadas com a bacteriúria evidenciada na urocultura com 7/10 dias.

OBJECTIVES: To determine the frequency and risk factors associated to bacteriuria after urinary catheterization in women submitted to elective gynecological surgery. METHODS: A cohort study was carried out among women submitted to gynecological surgery after urinary catheterization. This study took place at the "Instituto de Medicina Integral Professor Fernando Figueira" from January to May of 2007. Uroculture samples were collected during two periods: in the first 24 hours and seven to ten days after catheter removal. To demonstrate the association between risk factors and bacteriuria, the relative risk was calculated with a confidence interval of 95 percent. RESULTS: This study included 249 women. At 24 hours after catheter removal, 23.6 percent of the urocultures collected were positive, while on days 7 to 10 this was reduced to 11.1 percent. Of all participants studied only 2.4 percent had symptomatic bacteriuria. Risk of bacteriuria at 7/10 days was reduced when the patient reported a positive history of treatment for vulvovaginitis in the previous three months. However this association was not found after multivariate analysis. There was no significant association with age, education, stage of reproductive phase, number of pregnancies and deliveries, type and duration of surgery, type of anesthetics, use of prophylactic antibiotic, professional who introduced the catheter and time of urinary catheterization. CONCLUSION: Frequency of bacteriruria was 23.6 percent at 24 hours and 11.1 percent seven days after catheter removal. There was no association between bacteriuria at 7/10 days and any of the variables analyzed.

Association between periurethral colonization with uropathogens and subsequent bacteriuria in catheterized patients

To determine the number of catheterized patients who develop bacteriuria due to the presence of organisms in their periurethral flora, which may subsequently cause Urinary Tract Infection [UTI] in these patients. Non-interventional, cohort study. This study was conducted on patients of Medical Intensive Care, Surgical and Urology Units of Combined Military Hospital, Lahore, from February to April 2006. A total of 60 hospitalized patients, who were catheterized for various underlying diseases, were included in the study. Urine samples and periurethral swabs were obtained from all patients and cultured on appropriate culture media. Various tests used for the identification of microorganisms were: Gram-staining, catalase test, coagulase test and esculin hydrolysis for the identification of Gram-positive bacteria, API 20e for Gram-negative bacilli, whereas lactophenol blue preparation and germ tube test were used for the identification of yeasts. Out of 60 patients, 41[68.3%] were males and 19 [31.7%] were females. The mean duration of catheterization was 4.5 days. In males, culture of periurethral swabs revealed coagulase negative staphylococci in 11 [40.7%], Staphylococcus aureus in 10 [37%] and Enterococcus fecalis in 3 [11.1%] patients. In females, the organisms isolated were coagulase negative staphylococci in 4 [25%], Staphylococcus aureus in 4 [25%], Enterococcus fecalis in 4 [25%], Pseudomonas aeruginosa in 2 [12.5%], Escherichia coli in 3 [18.6%] and Candida albicans in 3 [18.6%] patients. Twenty nine patients developed bacteriuria [p < 0.05]. Escherichia coli was the commonest organism causing bacteriuria in either gender followed by other Gram-negative organisms. Coagulase negative Staphylococcus was isolated in the urine of one male patient only. In males, 2 [10%] out of 20 patients with Gram-negative bacteriuria were colonized by the same organism, whereas in females, 4 [44.4%] out of 9 bacteriuric patients were colonized by the same organism. Predominantly Gram-positive organisms colonized the periurethral area in males as well as in the majority of females, whereas Gram-negative bacteria were mainly responsible for the bacteriuria in both genders. There was a significant association between periurethral colonization and subsequent bacteriuria, however, prior colonization with a particular organism is not a decisive event in the initiation of bacteriuria

Asymptomatic bacteriuria in users of intrauterine devices

The aim of this study was to compare the frequency of asymptomatic bacteriuria in women who use intrauterine devices [lUDs] as contraceptive method with subjects who use tubal ligation [TL]. A cohort study was conducted on women who were candidates for IUD insertion or TL [control]. The patients were followed for three months, and urine cultures were assessed for bacteriuria at the end of study. Overall, 131 women [mean age, 31.9 +/- 4.25 years] in the IUD group and 78 [mean age, 32.1 +/- 4.0 years] in the control group were studied. The parity score was 2 or more in 72% of the women in the IUD group and in 74% of the controls. The average intercourse frequency was twice per week in 82% of IUD users and 80% of controls. Fifty-seven percent of the women in IUD group and 55%ofthe women in the control group had graduated from secondary school [high school]. Asymptomatic bacteriuria was detected in 13 IUD users [9.9%] and in 1 woman [1.3%] in the control group [risk ratio = 7.74, confidence interval: 1.03 to 58.03; P =.019]. The detected microorganism in the urine culture was Escherichia coli in 12 IUD users and in 1 patient in control group. Klebsiella was found in 1 IUD user. Use of an IUD is a risk factor for urinary tract infection and should be considered, especially in women with recurrent urinary tract infections

Bacteriúria assintomática / Asymptomatic bacteriuria

A bacteriúria assintomática (BA) é um evento relativamente freqüente na prática médica e que confronta o médico da necessidade de tratá-Ia ou não. A seguir, serão feitas algumas considerações sobre o achado de BA na urocultura

Bacteriuria in patients with gallbladder and biliary tract diseases.

Urinary tract infections (UTI) are important hospital acquired entities, resulting in bacteriuria indicated by the presence of significant numbers of bacteria in the urine. This study examined the prevalence of bacteriuria in our patients with gallbladder diseases. Three hundred and forty eight patients with various gallbladder (GB) diseases were enrolled in our study. Routine bacteriological cultures of midstream urine specimens were done. Significant bacteriuria was defined as the growth of 105 or more organisms in pure culture per milliliter of urine. Forty four (12.6%) of the patients (18 symptomatic; 26 asymptomatic) showed bacteriuria. Escherichia coli was the predominant isolate followed by Klebsiella pneumoniae, Enterobacter, Pseudomonas aeruginosa, Enterococci and several others. Thus UTI is also a frequent concomitant of gall bladder diseases and is a sign of the fact that kidneys are in a condition endangered by pyelonephritis.

Asymptomatic bacteriuria and inflammatory response urinary tract infection of elderly ambulatory women in nursing homes

Background. Bacteriuria = 10 to fifth CFU/ml is evidence of urinary tract infection in the absence of associated signs or symptoms. The presence of pyuria with asymptomatic bacteriuria established the response of elderly women against microorganisms capable of causing invasiveness or tissue injury of the urinary tract. Methods. The association between bacteriuria and pyuria was determined in 178 elderly, ambulatory women without symptoms of urinary tract infection in seven nursing homes. Urine culture results were subsequently analyzed in conjunction with absolute leukocyte count in urine. In this cross-sectional study, asymptomatic bacteriuria in elderly women was classified with and without pyuria. Results. The prevalence of asymptomatic bacteriuria was found in 44 (24.7 percent) elderly women. The presence of pyuria had a sensitivity of 63.6 percent for bacteriuria and a specificity of 91 percent. The positive predictive value for the presence of pyuria predicting those with bacteriuria was 70 percent, and the negative predictive value for the absence of pyuria predicting those without bacteriuria was 88.4 percent. Escherichia coli was the most common organism isolated in 81.8 percent of the women. Conclusions. bacteriuria = 10 to fifth CFU/ml associated with pyuria was detected in 77 percent of elderly women with asymptomatic urinary tract infections bacteriuria of < 10 to fifth CFU/ml with pyuria proves less sensitive as an indicator of urinary tract infection. Elderly women with pyuria but without bacteriuria should be studied for other causes of urinary tractinflammation

Bacteriúria em pacientes com diabetes mellitus / Bacteriuria in patients with diabetes mellitus

Realizamos o presente trabalho com o objetivo de compreender melhor a associaçäo: diabetes mellitus e infecçäo urinária (IU). Trezentos e dezesseis diabéticos (88 por cento ambulatoriais) fortam acompanhados por um período de um a oito anos. Verificou-se prevalência de 24,7 por cento de bacteriúria significativa (BS>- 105 germes/ml): 32,3 por cento entre mulheres e 13,4 por cento entre os homens. Ambos os grupos de diabéticos, com e sem BS, caracterizaram-se por terem 40 ou mais anos de idade, serem diabéticos näo-insulinodependentes e portadores das complicaçöes crônicas. Ainda näo diferiram quanto ao tempo e grau de controle da doenca. Entretanto, no grupo com BS houve maior número de pacientes internados e com outros fatores predisponentes: hiperplasia prostática, cistocele, calculose renal. Os agentes etiológicos mais frequentes foram E.coli e Klebsiella pneumoniae (61, 6 por cento e 15,2 por cento das BS, respectivamente) e houve 67,9 dos casos com BS e assintomáticos. As amostras testadas destas bactérias prevalentes foram sensíveis à maioria dos antimicrobianos comumente utilizados, com exceçäo da ampiclina. Assim, recomendamos a realizaçäo de urinocultura em diabéticos semelhantes aos deste estudo, que infelizmente, ainda representam a maioria dos que procuram os cuidados médicos, mesmo na ausência de evidência clínica e dos fatores correlacionados à mesma

Urinary tract infection in the elderly: a clinical study.

Urinary tract infection is one of the most common causes of infection in the elderly living in the community as well as in institutions. While the preventive measures involve the enhancement of immunological status, perineal hygiene and avoiding unnecessary instrumentation, the clinical manifestation predicting the outcome, the main objective of the study, is also no less important after the infection takes place. Cross-sectional study was designed recruiting 107 cases from the general medical wards to compare various relevant clinical parameters in terms of the final outcome. The result showed that the aged group 75 years old or more, the catheter-related cases, prior bedbound status, confusion, anorexia with nasogastric tube feeding, respiratory failure requiring mechanical ventilation, septic shock, the presence of candida in urine, the extreme temperature either less than 37 degrees C or more than 40 degrees C and finally the mistake in interpreting the gram stain of the urine were found more common in the dead group with statistical significance. Multiple logistic regression analysis revealed anorexia with nasogastric tube feeding, prior bedbound status, the need for mechanical ventilation, septic shock and extreme body temperature response independently predicted the outcome of the elderly with urinary tract infection.

Significance of pyuria and bacteria in chronic spinal cord injury Patients

Five hundred patients with chronic spinal cord injury have been studied clinically, radiologically and bacteriologically over a period of one year. Methods of urinary drainage included condom [300], catheter [63], bladder training [107] and intermittent catheterization [30]. 96% of patients had significant pyuria [>5 WBC/HPF]. Low pyuria level [5-30 WBC] was associated with 90% incidence of bacteriuria and 7.5% incidence of symptomatic urinary tract infection. Moderate pyuria [30-100 WBC] was 28%, incidence and high pyuria [>100 WBC] was 19%, incidence and both were similarly associated with 100% incidence of bacteriuria and 25% incidence of symptomatic urinary tract infection. Bacteriuria was presented in 91.2% of all patients. Symptomatic bacteriuria was presented in only 16.4% of bacteriuric patients. The most common isolated organisms were E. coli [65%] and Proteus mirabilis [22%]. In conclusion, low pyuria level [<30 WBC/HPF] has less bacteriuria and lower incidence of symptomatic urinary tract infection. On the other hand, pyuria level [>30 WBC/HPF] has a higher incidence of symptomatic infection. Symptomatic bacteriuria is presented in only 16.4% of bacteriuric patients. Antimicrobial therapy is recommended in pyuria level [>30 WBC/HPF] and symptomatic bacteriuria

When chronic prostatitis is to be considered?

We studied 50 patients with lower urinary symptoms, sexual symptoms and/or bacteruria. Their age ranged between 25-50 years. All patients were subjected to: full history taking, clinical and laboratory investigation including urine analysis and culture and sensetivity; prostatic smear analysis and culture; prostatic needle biopsy and culture. All specimens were grown on aerobic cultures and blood agar plates. The most common presentations of our cases were sexual troubles as weak erection [40%] and lower urinary symptoms as burning micturation [18%]. Significant bacteriuria was found in only 20% of patients and E.coli was the most common isolated organism. Infected prostatic secretion with pus cells over 100/H P.F. was found in most cases [45%]. Prostatic secretion, semen and prostatic needle biopsy cultures revealed bacteriological growth in 76%, 67%, and 72% respectively. Regarding cost benefit and invasion, prostatic biopsy was of significant value in diagnosis of chronic prostatitis

Asymptomatic bacteriuria in haemodialysis patients

This study was designed to assess the frequency significance and possible pathogenic factors of asymptomatic bacteriuria in chronic haemodialysis patients. A hundred patients suffering from endstage renal failure under regular haemodialysis treatment [divided into 3 groups according to the underlying cause of renal failure whether primary glomerulonephritis [forty cases] tubulointerstitial nephritis [thirty cases] or diabetic nephropathy [thirty cases] were randomely selected from the dialysis unit of Ain Shams University Hospital, El Sahil Teaching Hospital and Cairo Kidney Centre. None of these patients suffered symptoms nor signs suggestive of urinary tract infection and all were subjected to full history and clinical examination, clean catch midstream urine analysis with culture [aerobic and anaerobic]. Bacterial isolates were identified by bacteriological methods and sensitivity [when needed] in addition to microscopic examination for pus cells. Also, assessment of blood urea and serum creatinine were done. A subgroup of patients [proved to have asymptomatic bacteriuria 10 cases] as well as an equal subgroup of those having no significant bacteriuria were further studied by assessment of residual kidney function, total and differential WBCs counts, serum Ig[G], Ig[A] level, urinary Ig[A] level, opsonophagocytic function and migration inhibition test. Though we had high prevalence of significant bacteriuria in our patients [50%]. Pyuria was detected in only 14% of cases, all except one were associated with significant bacteriuria and the most prevalent organism was Staphylococcus aureus followed by Staph. saprophyticus. We didn't detect any significant correlation between significant bacteriuria and either age of the patients, duration, frequency of dialysis, blood urea or serum creatinine but female patients and chronic interstitial nephritis were associated with significant high prevalence of assymptomatic bacteriuria. In the two subgroups studied no correlation was detected between significant bacteriuria and either W.B.Cs count, residual kidney function, macrophage migration inhibition test, opsonophagocytic activity, Ig[A] or Ig[M] level. Though low Ig[G] level was associated with higher prevalence of asymptomatic bacteriuria. It is conducted that local factors may be more important than systemic factors in the pathogenesis of asymptomatic bacteriuria in haemodialysis patients and that routine urine analysis should be regularly performed in these patients to detect and possibly treat such cases especially female patients and cases of chronic interstitial nephritis

Diagnóstico, pronóstico y tratamiento del reflujo vesicoureteral de primero a tercer grados: su perspectiva futura / Diagnosis, prognosis and treatment of vesicoureteral reflux of first to third degrees: future perspectives

Se analizaron los expedientes de los 160 pacientes con reflujo vesicoureteral (RVU), pero solamente 86 reunieron todos los requisitos de información para ser incluidos en el estudio. Se investigaron al momento del diagnóstico edad, existencia de familiares (especialmente hermanos con RVU, manifestaciones clínicas, sexo, grado de reflujo, lado afectado, clasificación en primario o secundrio, trastornos petológicos acompañantes, presencia o no de nefropatía de reflujo, tratamiento realizado y progreso de la enfermedad. Para los efectos de este estudio, los RVU de grados I a III se consideraron de bajo grado, pues el daño que producen en las vías urinarias superiores es limitado. Los exámenes de laboratorio efectuasdos fueron biometría hemática, química sanguínea, análisis general de orina, urocultivo, depuración de creatinina, estudio imagenológicos urografía excretora, cistouretrograma miccional, ultrasonido renal y estudios especiales realizados en algunos pacientes, como cistometría, estudios endoscópicos, biopsias renales, etcétera. El tratamiento fue variado, y dependió del grado de reflujo, edad del niño, presencia de secuelas al momento del diagnóstico y etiología. En este estudio se analizó en forma separada a los pacientes con RVU de bajo grado. El grado consistió en 40 pacientes, de los que 18 eran del sexo masculino y 22 del femenino; los límites de edad se encontraron entre el periodo del recién nacido hasta los 11 años de edad, con una media de tres años. De los 40 pacientes, 28 se clasificaron casos de RVU primario y 12 de tipo secundario. Siete eran del grado I y 14 del grado III. El tratamiento fue siempre médico en primera instancia y, según grado de reflujo, secuelas en el riñon, edad del paciente y fracaso del tratamiento médico en algunos pacientes, se procedió con el tratamiento quirúrgico

Asymptomatic bacteriuria in chronic haemodialysis patients

Symptomless bacteriuria could be considered as a dormant source of overt urinary tract infection [UTI] and possible bacteremia in maintenance haemodialysis [HD] population. The study was conducted to detemine the magnitude and pattern of asymptomatic bacteriuria among HD patients and show the effect of HD session on the bacterial counts. Forty-four patients with chronic renal failure on regular HD treatments [five hours twice weekly] for 5 to 57 months duration were included. Bacterial counts were performed twice for each patient before and after dialysis to determine the effect of HD on total viable bacteria [T.V.B.], Staphylococcus aureus, Streptococcus haemolyticus, E. coli, Proteus, Klebsiella and Pseudomonas areuginosa. It was found that thirty patients [72.7%] showed positive urine cultures, 18% of the patients showed. an increase of the bacterial counts in the post-dialysis urine samples and 24% showed decrease of the bactrial counts in the post-dialysis samples. The difference was not statistically significant [P > 0.05]. Urine volume and haemoglobin level were found to be significantly lower, while serum aspartate and alanine aminotransferase [AST and ALT] were significantly higher in bacteriuric group than those in nonbacteriuric group. Age, sex, clinical data and serum creatinine, urea, glucose, calcium, phosphorus and albumin did not significantly differ in the two comparison groups. The bacteria encountered in the asymptomatic bacteriuric HD patients were Staphylococcus aureus [86.8%], Streptococci spp. [52.7%], E. coli [37.2%], Klebsiella spp. [18.6%], Proteus [12.4%] and Pseudomonas spp. [12.4%]. There were no significant differences in bacterial counts of the various types of bacteria before and after dialysis. In vitro sensitivity to antibiotics showed that more than 80% of isolated strain; are sensitive to Norfloxacin

An unusual infected hydrocele: a case report

Of acute scrotal lesions in the neonates, cases needing emergent exploration are quite rare and differential diagnosis of them is not easy. Only a few cases of inflamed hydroceles occurring in young boys have been reported to have been caused by bacterial infection in the literature. We couldn't find any case concerning simultaneous bacterial infection in urine and hydrocele by the same organisms. We present an unusual case of infected hydrocele in a neonate with bacteriuria.

Bacteriuria e infección urinaria en pacientes ancianos / Urinary tract infection bacteriuria in elderly patients

La infección del tracto urinario es una enfermedad importante en los ancianos. Su prevalencia, etiología, manifestaciones clínicas y manejo se diferencian sifnificativamente de la infección observada en la población general. La bacteriuria es un problema serio de los pacientes añosos que residen en las Instituciones geriátricas. El tratamiento de la bacteriuria asintomática no tiene ningún beneficio potencial y, por lo tanto, no se recomienda

Bacteriuria and pregnancy outcome: a prospective hospital-based study in Pakistan women

The prevalence of bacteriuria in Pakistani women and its association with complications of pregnancy was studied. Out of 1579 women,77 had bacteriuria [4.8%]. There was no association of age, gravidity, parity, haemoglobin, pre-eclampsia, mode of delivery, gestational age at delivery, preterm delivery and low birth-weight with presence of bacteriuria. With detection and treatment the pregnancy outcome of women with bacteriuria in pregnancy was the same as that of those without

Infecciones urinarias e inmunodeficiencias / Urinary infections associated with inmunoallergic disease

Se estudiaron 12 pacientes con manifestaciones de infecciones urinarias repetitivas o recidivantes en forma crónica. Dichos pacientes previo urocultivo y antibiograma con posterior tratamiento antibiótico específico continuaban con manifestaciones clínicas de bacteriuria por más de cuatro años. Todos los casos estudiados corresponden al sexo femenino. Sin alteraciones anatómicas demostrables del tracto urinario, ni causas obstructivas que justificaran la sintomatología. Un alto porcentaje de pacientes presentaban asociados cuadros inmunológicos, como Rinosinusitis crónica; Asma Bronquial; dermatitis eczematosa y Rinosisnusitis con Asma Bronquial. Se les estudió el sistema inmune competente humoral y celular. Se realizó inmunoestimulación específica e inespecífica, en períodos asintomáticos, siguiendo con la antibioticoterapia adecuada en el período de infección. El análisis de los resultados obtenidos abre una perspectiva de estudio y terapéutica interdisciplinaria del huésped, tendiendo a dar una respuesta a pacientes que con sus problemas padecen una considerable morbilidad y conducen a menudo a menudo a una severa incapacidad
