Tuberculosis miliar con diseminación renal y genitourinaria, Hospital Escuela Universitario, Honduras, 2017 / Tuberculosis Miliar with Renal and Genitourinary Dissemination, University School Hospital. Honduras, 2017

La tuberculosis continúa siendo un reto diagnóstico al presentarse con características clínicas poco usuales. Objetivo: exponer las características clínicas en un caso inusual de tuberculosis miliar, con diseminación genitourinaria. Presentación del caso clínico: p aciente masculino de 48 años, agricultor, de escasos recursos económicos, sin comorbilidades previas; presentó sintomatología constitucional, pérdida de peso, fiebre y dolor lumbar irradiado a ambos flancos de la región abdominal, de características específicas, de un mes de evolución, acompañado de disuria y oliguria, negó síntomas respiratorios. Al examen físico, luce crónicamente enfermo, en mal estado nutricional, sin deterioro de la conciencia, no evidenció adenopatías cervicales ni inguinales, sin presencia de signos pulmonares y con leve dolor renal bilateral a la puño percusión;en área genital se identifica una masa de borde regular, móvil, sobre el polo superior del testículo derecho. Examen hematológico, presencia de Bicitopenia (anemia microcitica hipocromica y trombocitopenia leve). Además con hiperazoemia e hiperkalemia en la bioquímica sanguínea refractaria al tratamiento; en gases arteriales acidosis metabólica con anión gap elevado, por lo que fue sometido a hemodiálisis aguda. A través de los estudios imagenológicos, por medio de la bacteria alcohol acido resistente de sedimento urinario seriado y la tinción Ziehl Neelsen en orina, se determinó el diagnóstico yse inició terapia antifimica. Conclusión: Es necesario considerar a la tuberculosis como diagnóstico diferencial, especialmente en presentaciones poco usuales, dado que es endémica en Honduras...(AU)

Multidetector computed tomography has replaced conventional intravenous excretory urography in imaging of the kidneys: a scoping review of multidetector computed tomography findings in renal tuberculosis

Background: Tuberculosis (TB) is a worldwide infectious disease burden, especially in non-developed countries, with increased morbidity and mortality among human immunodeficiency virus (HIV)-infected patients. Extrapulmonary TB is rare and renal TB is one of the commonest manifestations. The end result of renal TB is end-stage renal disease; however, this can be avoided if the diagnosis is made early. The diagnosis of renal TB is challenging because of the non-specific presentation and low sensitivity of clinical tests. Although the sequel of TB infection in the kidney causes varying manifestations depending on the stage of the disease, multidetector computed tomography (MDCT) is capable of demonstrating early findings. We performed a 20-year scoping review of MDCT findings in renal TB to promote awareness. Aim: To identify specific MDCT imaging characteristics of renal TB, promote early diagnosis and increase awareness of the typical imaging features. Methods and material: We searched published and unpublished literature from 1997 to 2017 using a combination of search terms on electronic databases. We followed the Joanna Briggs Institute guidelines. Results: A total of 150 articles were identified, of which 145 were found through electronic search engines and 5 were obtained from grey literature. Seventy-nine articles that fulfilled our inclusion criteria were reviewed. These included original research, case reports, literature review, organisational reports and grey literature. Conclusion: Multidetector computed tomography can reproduce images comparable with intravenous excretory urography; together with advantages of being able to better assess the renal parenchyma and surrounding spaces, it is important in suggesting the diagnosis of renal TB and clinicians should consider including MDCT when investigating patients with recurrent urinary tract infection not responding to usual antimicrobial therapy

Tuberculosis miliar con diseminación renal y genitourinaria: reporte de un caso / Miliary tuberculosis, with renal and genitourinary disemination; Case Report

Antecedentes: A pesar de los grandes avances en la medicina contemporánea; la Tuberculosis continúa siendo un reto diagnóstico, en especial al presentarse con características clínicas poco usuales. Caso clínico: Paciente masculino de 48 años, agri-cultor, de escasos recursos económicos, sin comorbilidades previas, el cual presenta sintomatología constitucional, pérdida de peso, iebre y dolor lumbar irradiado a ambos lancos de la región abdominal, de características poco especíicas, de un mes de evolución; acompañado de disuria y oliguria, y niega síntomas respiratorios. Al examen físico luce crónicamente enfermo, en mal estado nutricio-nal, sin deterioro de la conciencia, no se evidencia adenopatías cervicales ni inguinales; sin presencia de signos pulmonares, con leve dolor con la puño percusión renal bilateral, en el área genital, se identiica una masa de borde regular, móvil sobre el polo superior del testículo derecho. En el examen hematológico con presencia de Bicitopenia anemia microcitica hipocromica y trombocitopenia leve, en gases arteriales acidosis metabólica con Anión Gap elevado, además con hiperazoemia e hiperkalemia en la bioquímica sanguínea refractaria al tratamiento, razón por la cual fue sometido a Hemodiálisis aguda. Al evaluar radiografía de tórax se observa patrón micro-nodular difuso, no se realiza baciloscopias por falta de expectoración ni por lavado gástrico, en el ultrasonido renal y de vías urinarias se visualizó nefromegalia y la presencia de masa heterogénea de aspecto granulomatoso en testículo derecho; por lo que se solicitó tomografía toracoabdominal, en donde se observa patrón micronodular múltiple a nivel pulmonar, con afectación renal, ganglionar y testicular, se solicita BAAR de sedimento urinario seriado con resultados positivos, y la tinción Ziehl Neelsen en orina con resultado positivo; con ello se inicia terapia antiimica. Discusión: La Tuberculosis renal no tiene un cuadro clínico clásico; generalmente se presenta con manifestaciones atípicas; como en nuestro caso con sintomatología urinaria, hiperazoemia que culmino en terapia de restitución renal de emergencia, con posterior recuperación de la función renal.

Chronic kidney disease related to renal tuberculosis: a case report

Abstract: Genitourinary tuberculosis (TB) is the third most common form of extrapulmonary TB. A 34-year-old man with severe kidney function loss secondary to renal TB initially presented with urinary symptoms, including dysuria and polacyuria. The diagnosis was based on clinical history and laboratory tests; the urinalysis revealed acid-fast bacilli. The patient's condition stabilized after beginning TB-specific treatment, but the right kidney function loss persisted. Renal TB can lead to irreversible loss of renal function. As such, renal function should be considered in all patients from TB-endemic areas who present with urinary symptoms and whose urine cultures are negative for common pathogens.

Abordagem diagnóstica da tuberculose pleural, ganglionar, renal e de sistema nervoso central / Diagnostic Approach to Tuberculosis in the Pleura, Lymph Nodes, Kidneys, and Central Nervous System

O objetivo do presente artigo foi relatar a abordagem diagnóstica da tuberculose pleural, ganglionar, renal e do sistema nervoso central. A forma mais frequente entre essas formas de tuberculose no Brasil é a tuberculose pleural, cujo diagnóstico na prática clínica baseia-se no exame histopatológico, com uma alternativa relatada nos últimos anos: a dosagem da enzima adenosina desaminase. A maioria dos achados laboratoriais encontrados implica na condição paucibacilar dessas formas extrapulmonares

The objective of this study was to report the diagnostic approach to tuberculosis of the pleura, lymph nodes, kidneys, and central nervous system. In Brazil, the most common extrapulmonary form of tuberculosis is that afecting the pleura. In clinical practice, pleural tuberculosis is typically diagnosed on the basis of the histopathological examination. However, in recent years, the determination of adenosine deaminase levels has been used as an alternative. Most laboratory indings indicate that these extrapulmonary forms are paucibacillary

Diagnóstico bacteriológico de tuberculosis renal: experiencia del Laboratorio Regional de Tuberculosis de la provincia de Córdoba

Dada la considerable incidencia de tuberculosis renal entre enfermos con tuberculosis pulmonar, nos propusimos estudiar la frecuencia de esta asociación en pacientes atendidos en centros de salud públicos y privados de Córdoba a lo largo del período 1997-2009. Se tomó en consideración la incidencia según el sexo y las especies del complejo Mycobacterium tuberculosis identificadas. El análisis de 948 muestras de orina de 383 pacientes indicó tuberculosis renal en 24 casos (6,3 %), con presencia mayoritaria de Mycobacterium tuberculosis (95,8 %) y presencia de Mycobacterium bovis en 4,2 % de los casos. La asociación tuberculosis renal-tuberculosis pulmonar activa se encontró en 6 casos. En esta investigación quedó demostrada la importancia del cultivo seriado de muestras de orina y la conveniencia de cultivar en medios sólidos y líquidos. Asimismo, el aislamiento de Mycobacterium bovis pone de relieve la importancia de usar el medio Stonebrink junto con el medio de Lowenstein-Jensen. El medio líquido no tuvo un aporte significativo al diagnóstico de tuberculosis renal; sin embargo, el cultivo de muestras seriadas aumentó la sensibilidad de la detección.

Bacteriological diagnosis of renal tuberculosis: an experience at the Regional Tuberculosis Laboratory in Córdoba province, Argentina. Given the incidence of renal tuberculosis in patients suffering of pulmonary tuberculosis, we seek to study both the frequency of this association in diagnosed cases of renal tuberculosis and the Mycobacterium tuberculosis complex species that were identified (period 1997-2009), observing its incidence by sex, demonstrating the importance of serial culture of urine samples and evaluating the convenience of using solid and liquid media. The analysis of urine samples from 383 patients indicated renal tuberculosis in 24 cases; in most cases, (95.8 %) Mycobacterium tuberculosis complex species prevailed, whereas the presence of Mycobacterium bovis accounted for 4.2 % of the cases. The association of pulmonary and renal tuberculosis was found in 6 cases. The isolation of Mycobacterium bovis indicates the importance of including Stonebrink medium along with Lowenstein- Jensen medium. The liquid medium made no significant contribution to the diagnosis of renal tuberculosis, but indeed, cultivating serial samples increases sensitivity.

Tuberculosis renal / Genitourinary tuberculosis

Paciente femenina de 62 años que consultó por dolor lumbar crónico y fiebre, en quien se diagnosticaban infecciones urinarias a repetición y cuadros de litiasis renal. Se realizaron baciloscopías en orina observándose bacilos ácido alcohol resistentes. La tuberculosis renal es una patología poco frecuente, representa apenas el 3% de las formas extrapulmonares y el diagnóstico se basa en una alta sospecha clínica.

End-stage renal disease due to delayed diagnosis of renal tuberculosis: a fatal case report

Renal TB is difficult to diagnose, because many patients present themselves with lower urinary symptoms which are typical of bacterial cystitis. We report a case of a young woman with renal TB and ESRD. She was admitted with complaints of adynamia, anorexia, fever, weight loss, dysuria and generalized edema for 10 months. At physical examination she was febrile (39°C), and her abdomen had increased volume and was painful at palpation. Laboratorial tests showed serum urea=220mg/dL, creatinine=6.6mg/dL, hemoglobin=7.9g/dL, hematocrit=24.3 percent, leukocytes=33,600/mm³ and platelets=664,000/mm³. Urinalysis showed an acid urine (pH=5.0), leukocyturia (2+/4+) and mild proteinuria (1+/4+). She was also oliguric (urinary volume <400mL/day). Abdominal echography showed thick and contracted bladder walls and heterogeneous liquid collection in the left pelvic region. Two laparotomies were performed, in which abscess in pelvic region was found. Anti-peritoneal tuberculosis treatment with rifampin, isoniazid and pyrazinamide was started. During the follow-up, the urine culture was found to be positive for M. tuberculosis. Six months later the patient had complaints of abdominal pain and dysuria. New laboratorial tests showed serum urea=187mg/dL, creatinine=8.0mg/dL, potassium=6.5mEq/L. Hemodialysis was then started. The CT scan showed signs of chronic nephropathy, dilated calyces and thinning of renal cortex in both kidneys and severe dilation of ureter. The patient developed neurologic symptoms, suggesting tuberculous meningoencephalitis, and died despite of support measures adopted. The patient had ESRD due to secondary uropathy to prolonged tuberculosis of urinary tract that was caused by delayed clinical and laboratorial diagnosis, and probably also due to inadequate antituberculous drugs administration.

Tuberculose genitourinária: relato de dois casos / Genitourinary tuberculosis: report of two cases

A incidência da tuberculose tem diminuido nos últimos anos. No entanto, em consequência da sua apresentaçäo insidiosa, permanece clinicamente importante. As menifestações radiológicas säo variáveis e seu reconhecimento é de suma importância. Nos estádios iniciais, a urografia excretora pode ser normal, mesmo na presença de culturas positivas para bacilos álccol-ácido resistentes. Mais tarde, pode haver irregularidade dos cálices. O uso da ultra-sonografia na avaliaçäo da tuberculose renal tem sido esporadicamente descrito na literatura. O ultra-som pode determinar o local da obstruçäo na presença de um rim excluso. A tomografia computadorizada pode demonstrar a presença e o local da obstruçäo. Qualquer vestígio de funçäo renal pode ser avaliado após injeçäo de contraste. A facilidade de detectar calcuificações supera á do raio-X. O parênquima renal também pode ser avaliado no rim abstruído.
