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

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
