Phenotypic expression variability in Best Disease: a purpose of a series of cases

Rev. bras. oftalmol; 77 (2), 2018
Abstract The objective of the following work is to document the phenotypic expression variability in Best Disease in first-degree relatives. The information was collected by assessing medical notes, interviewing the patient and obtaining photographic record of the diagnostic methods to which the patient ...

HCMV UL97 phosphotransferase gene mutations may be associated with antiviral resistance in immunocompromised patients in Belém, PA, Northern Brazil

Abstract INTRODUCTION: Human cytomegalovirus is one of the causes of opportunist infections in immunocompromised patients, and is triggered by factors such as state of viral latency, weakened immune responses, and development of antiviral resistance to ganciclovir, the only drug offered by the public h...

Diagnóstico tardío de síndrome WHIM
Late diagnosis of WHIM sydrome

Medicina (B.Aires); 78 (2), 2018
El síndrome WHIM es una inmunodeficiencia primaria de herencia autosómica dominante, debida a mutaciones en el gen CXCR4, que se caracteriza por verrugas cutáneo-mucosas, hipogammaglobulinemia, infecciones bacterianas recurrentes y mielocatesis. El tratamiento se basa en el uso de antibióticos profil...

HIV-1 genetic diversity and resistance to antiretroviral drugs among pregnant women in Ribeirão Preto (SP), Brazil. Cross-sectional study

Säo Paulo med. j; 136 (2), 2018
ABSTRACT BACKGROUND: Increasing genetic diversity of HIV-1 and emergence of drug-resistant mutations may reduce the efficacy of antiretroviral therapy and prophylaxis that are used to prevent mother-to-child transmission. The aim of this study was to assess the genetic diversity and prevalence of drug-r...

Prevalencia de resistencia a los anti-retrovirales en niños y adolescentes uruguayos infectados con el virus de la inmunodeficiencia humana en el Centro de Referencia VIH-SIDA. Centro Hospitalario Pereira Rossell. Montevideo-Uruguay

Rev. chil. infectol; 35 (5), 2018
Resumen Introducción: A nivel mundial, la tasa global de resistencia primaria y secundaria a los anti-retrovirales (ARV) es de 15 y 40%, respectivamente. Se desconoce su prevalencia en Uruguay. Objetivo: Conocer la prevalencia de resistencia a los ARV en niños y adolescentes uruguayos bajo 15 años d...

Utilidad de la cuantificación de carga viral de VIH en líquido cefalorraquídeo, a propósito de un caso

Rev. chil. infectol; 35 (5), 2018
Resumen La detección de virus en el líquido cefalorraquídeo (LCR) en pacientes infectados por VIH con carga viral (CV) indetectable en el plasma se ha denominado escape viral. Estas fugas pueden ser asintomáticas o asociadas con enfermedad neurológica. La discordancia de la carga viral de VIH entre ...

Identification of a novel UMOD mutation (c. 163G>A) in a Brazilian family with autosomal dominant tubulointerstitial kidney disease

Braz. j. med. biol. res; 51 (3), 2018
Autosomal dominant tubulointerstitial kidney disease (ADTKD) is characterized by autosomal dominant inheritance, progressive chronic kidney disease, and a bland urinary sediment. ADTKD is most commonly caused by mutations in the UMOD gene encoding uromodulin (ADTKD-UMOD). We herein report the first confi...

CCAT2 is an oncogenic long non-coding RNA in pancreatic ductal adenocarcinoma

Biol. Res; 51 (), 2018
Abstract Background Pancreatic ductal adenocarcinoma (PDAC) is highly aggressive with poor prognosis. Long non-coding RNAs (lncRNAs), a group of non-coding RNAs, play important roles in the progression of PDAC. This study aimed to investigate the potential involvement of lncRNA CCAT2 in PDAC tumorigenes...

Ferritin light chain gene mutations in two Brazilian families with hereditary hyperferritinemia-cataract syndrome

Einstein (Säo Paulo); 15 (4), 2017
ABSTRACT Hereditary hyperferritinemia-cataract syndrome is an autosomal dominant genetic disorder associated with mutations in the 5'UTR region of the ferritin light chain gene. These mutations cause the ferritin levels to increase even in the absence of iron overload. Patients also develop bilateral cat...
