ABSTRACT

Introducción: La urolitiasis se ha incrementado en las últimas décadas. La enfermedad renal poliquística autosómica dominante (ERPAD), enfermedad renal hereditaria más frecuente, ocupa un lugar preponderante. Objetivos: Identificar la frecuencia de presentación de los trastornos metabólicos urinarios en pacientes litiásicos cubanos con ERPAD y sin ella Métodos: Estudio descriptivo, transversal. Fueron estudiados 579 pacientes adultos sin ERPAD, seleccionados por muestreo simple aleatorio y los 21 pacientes con ERPAD, del total de pacientes con litiasis urinaria que se realizó estudio metabólico renal en el Laboratorio de Fisiopatología Renal del Instituto de Nefrología, en el periodo 2010-2015. Los datos fueron tomados de la historia clínica y del informe de estudio metabólico renal. La información se procesó de forma automatizada (SPSS 22.0). Se utilizó el promedio, desviación estándar, análisis de distribución de frecuencias y el test de homogeneidad. Resultados: En los pacientes con ERPAD predominó el sexo femenino (57,1 por ciento), mientras que en los pacientes sin ERPAD, el masculino (63,4 por ciento). Los trastornos más frecuentes en la población no poliquística fueron hipercalciuria (45,3 por ciento) e hipofosfatemia (17,1 por ciento). En los poliquísticos, aclaramiento aumentado de ácido úrico (38,1 por ciento) e hipercalciuria (23,8 por ciento). Se encontraron diferencias estadísticamente significativas para aumento del aclaramiento de ácido úrico (p = 0,01) e hiperfosfatemia (p = 0,04). Conclusiones: Los principales trastornos metabólicos de los pacientes litiásicos, tanto poliquísticos como no poliquísticos, son el aclaramiento de ácido úrico aumentado, hipercalciuria, hiperuricosuria e hipofosfatemia, aunque el orden de presentación es diferente. El aclaramiento de ácido úrico aumentado y la hiperfosfatemia se presentan con mayor frecuencia en los pacientes litiásicos poliquísticos(AU)


Introduction: Urolithiasis has increased in recent decades. Autosomal dominant polycystic kidney disease (ADPKD), the most common of all hereditary kidney diseases, occupies a predominant position in terms of incidence. Objectives: Identify the frequency of occurrence of urinary metabolic disorders in Cuban urolithiasis patients with and without ADPKD. Methods: A descriptive cross-sectional study was conducted of 579 adult patients without ADPKD selected by simple random sampling, and 21 patients with ADPKD, from the total urolithiasis patients undergoing renal metabolic evaluation at the Renal Physiopathology Laboratory of the Institute of Nephrology in the period 2010-2015. Data were obtained from medical records and reports of renal metabolic studies. Information was processed with the statistical software SPSS version 22.0. Average and standard deviation were estimated and use was made of frequency distribution analysis and homogeneity testing. Results: A predominance was found of female sex among patients with ADPKD (57.1 percent) and male sex among patients without ADPKD (63.4 percent). The most common disorders were hypercalciuria (45.3 percent) and hypophosphatemia (17.1 percent) in the non-polycystic population, and increased uric acid clearance (38.1 percent) and hypercalciuria (23.8 percent) in polycystic patients. Statistically significant differences were found in uric acid clearance increase (p = 0.01) and hyperphosphatemia (p = 0.04). Conclusions: The main metabolic disorders of lithiasis patients, polycystic as well as non-polycystic, are increased uric acid clearance, hypercalciuria, hyperuricosuria and hypophosphatemia, with a varying order of presentation. Increased uric acid clearance and hyperphosphatemia are more common in polycystic lithiasis patients(AU)

ABSTRACT

OBJECTIVE@#To carry out genetic testing and prenatal diagnosis for a Chinese couple whom had conceived two fetuses featuring multiple malformations including polycystic kidney, polydactyly and encephalocele.@*METHODS@#Following elective abortion, the fetus from the second pregnancy was subjected to whole exome sequencing. Suspected pathogenic variants were verified by Sanger sequencing of the fetus and its parents.@*RESULTS@#The fetus was found to harbor compound heterozygous variants of the CEP290 gene, namely c.2743G>T (p.E915X) and c.2587-2A>T, which were respectively inherited from its father and mother. The same variants were not detected among 100 healthy controls nor reported previously. Bioinformatic analysis suggested both variants to be deleterious. The fetus was diagnosed with Meckel-Gruber syndrome. Prenatal diagnosis for the couple during their next pregnancy suggested that the fetus did not carry the above pathogenic variants.@*CONCLUSION@#The compound heterozygous variants of the CEP290 gene probably underlay the pathogenesis of Meckel-Gruber syndrome in the second fetus. Above finding has provided a basis for genetic counseling and prenatal diagnosis for the couple, and also enriched the mutational spectrum of the CEP290 gene.

ABSTRACT

Many diseases can be associated with kidney cysts and they may be classified as hereditary and non-hereditary renal cystic disease. The first group can be sub-classified as autosomal recessive cystic disease, such as autosomal recessive polycystic kidney disease and nephronophthisis, as autosomal dominant kidney disease such as autosomal dominant polycystic kidney disease, glomerulocystic disease and tuberous sclerosis, and as cysts associated with syndromes. Cystic dysplasia, multicystic dysplastic kidney, simple cyst, multilocular cysts, Wilm's tumor and acquired cystic kidney disease are classified in the second group. The genetic study of renal cysts is becoming increasingly important, due to the possible therapeutic interventions that could be devised in the future. The aim of this review is to provide a fast and easy clinical approach to renal cystc.

ABSTRACT

El síndrome de Joubert (SJ) es una afección autosómica recesiva caracterizada por taquipnea neonatal episódica, anormalidades oculomotoras (apraxia oculomotora, nistagmus, estrabismo), hipotonía desde el nacimiento con posterior aparición de ataxia, retardo madurativo, deficiencia mental y algunos rasgos faciales distintivos. Es clínicamente heterogéneo presentando algunos pacientes amaurosis congénita de Leber, nefronoptisis y/o enfermedad renal medular quística. Existe igualmente heterogeneidad genética. Las imágenes de resonancia magnética revelan hipoplasia/aplasia de vermis, prominencia y elongación de los pedúnculos cerebelosos superiores y fosa interpeduncular ensanchada, evocando conjuntamente la silueta de una muela o “signo del molar”. También se evidencian alteraciones morfológicas del 4º ventrículo, que adquiere forma de “alas de murciélago”. El SJ es incluido actualmente en el espectro malformativo de síndromes cerebelo-óculo-renales (SCOR). Objetivo: Presentar los casos clínicos de dos pacientes con SJ diagnosticado por hallazgos clínicos y resonancia magnética, y revisar los aportes de las recientes investigaciones genéticas.

ABSTRACT

La presencia de carcinoma de células renales durante la evolución de una enfermedad poliquística renal autosómica dominante es muy rara y poco reportada en la literatura internacional. Se reporta un caso de enfermedad poliquística renal asociado con carcinoma de células renales. La forma de presentación fue un síndrome febril prolongado, pérdida de peso, eritrosedimentación acelerada y aumento de volumen de una imagen compleja en el riñón izquierdo que duplicó su tamaño en un mes. En el acto quirúrgico se comprobó presencia de ganglios parahiliares renales y paraaórticos infiltrados; en el estudio patológico macroscópico, infiltración de la vena renal, y en el microscópico, presencia de tejido neoplásico en el parénquima renal

ABSTRACT

Meckel Gruber syndrome is an uncommon, lethal, autosomal recessive disorder, associated consistently with polycystic kidneys, posterior encephalocoele and polydactly. We report three cases in non-consanguineous marriages, suggesting that the single gene defect occurs more commonly in non-consanguineous marriages than mutant genes associated with other autosomal recessive disorders that are usually related with consanguineous marriages. The usefulness of prenatal diagnosis is discussed.

ABSTRACT

We herein describe two cases of Meckel-Gruber Syndrome identified in stilborn infants. Both had all three elements of the classical triad, namely, occipital encephalocele, renal cystic dysplasia and post-axial polydactyly. In addition, many of the other well-known accompanying abnormalities were present. Awareness of this entity in this region is important because of its high risk of recurrence in subsequent pregnancies

ABSTRACT

Se hace una definición conceptual de la poliquistosis renal congénita, descubriendose su carácter hereditario. Se señalan además, las diferentes clasificaciones propuestas por varios autores. Se presentan tres casos que fallecieron a causa de esta enfermedad, dos de ellos eran hermanas, y la tercera tenía antecedentes de hermana fallecida por igual diagnóstico. En dos de las pacientes se asoció y predominó la sintomatología hepática y en la tercera tuvo predominio el cuadro de insuficiencia renal crónica. Se hace, finalmente, breve discusión de los casos presentados
