Liver Fibrosis progression using Fibroscan in HIV/HCV coinfected patients with undetectable HIV viral load.

INTRODUCTION: Several factors such as duration of infection, age, male gender, consumption of alcohol, HIV infection and low CD4 count have been associated with fibrosis progression rate. However, it is relatively scarce, the knowledge about the liver fibrosis progression rate in HIV-infected patients with undetectable HIV viral load (VL). For this reason, we performed the present study. MATERIALS AND METHODS: Observational and multicenter study (2008-2012) conducted in four hospitals of the northern Spain. HIV/HCV (hepatitis c) virus coinfected patients ≥18 years on stable combination antiretroviral therapy (cART) (≥6 months) and with a HIV VL <50 copies/mL were selected to analyze their liver fibrosis progression. Fibrosis progression was assessed using a Fibroscan® (502 STEP 3 model) and measuring a basal test and a second one at least 12 months apart from baseline. This evolution was compared with different variables such as duration of HIV/HCV coinfection, gender, age, previous treatment for HCV, HCV genotype, CD4 lymphocyte counts and the cART employed at the basal test. RESULTS: A total of 608 patients were included (median age 29.4 years, 71.7% men). Of these, 463 patients met the inclusion criteria. In these patients, the liver fibrosis progression was nearly flat and the only variables related to a higher liver fibrosis progression were the increasing age of the patients (p=0.02) and the duration of the coinfection (p=0.001). CD4 lymphocyte counts showed a tendency to improved liver fibrosis (p=0.056). CONCLUSIONS: In HIV/HCV coinfected patients on stable cART and HIV undetectable VL, the increase in liver fibrosis rate progression was nearly flat, although it was significantly associated with the duration of the coinfection and the age of the patient. The beneficial effects of the cART were independent of the antiretroviral drug employed. A tendency to a lower fibrosis progression was observed in those patients with a higher CD4 count.

Diferencias clínicas y terapéuticas de la afectación neurooftalmológica secundaria a sífilis / Clinical and therapeutic differences in neuro-ophthalmological involvement secondary to syphilis

Introducción. Existen múltiples formas de afectación neurooftalmológica secundaria a sífilis, no siempre bien conocidas. Nuestro objetivo es conocer las diferencias clínicas y de tratamiento en estos pacientes. Casos clínicos. Se incluyeron ocho pacientes diagnosticados de afectación ocular y neurooftalmológica por sífilis durante los años 2012 y 2013. Cinco presentaron uveítis, siendo la panuveítis la forma más frecuente, con tres casos. Dos casos presentaron papiledema, y otro, neuropatía óptica retrobulbar. Un 62,5% fue diagnosticado de neurosífilis, cuya presencia se relacionó con la afectación del nervio óptico (p = 0,035). Ninguno de ellos presentó positividad para VDRL en el líquido cefalorraquídeo, y se diagnosticaron por la presencia de anticuerpos FTA junto con hiperproteinorraquia, pleocitosis linfocitaria o síntesis intratecal de anticuerpos. En ausencia de uveítis, se produjo un retraso diagnóstico medio de 2,6 meses (p = 0,047). Todos los pacientes, salvo uno que precisó vitrectomía, evolucionaron favorablemente con antibioterapia intravenosa. Conclusiones. En casos de afectación neurooftalmológica, inflamatoria y no inflamatoria, el clínico debe tener en cuenta la sífilis como potencial etiología para evitar un retraso diagnóstico, puesto que un adecuado tratamiento precoz puede evitar una pérdida de visión permanente (AU)

Introduction. There are many forms of neuro-ophthalmological involvement secondary to syphilis, and not all of them are well known. Our aim is to determine the clinical and therapeutic differences in these patients. Case reports. Our sample included eight patients diagnosed with an ocular and neuro-ophthalmological disorder due to syphilis over the years 2012 and 2013. Five of them presented uveitis, pan-eveitis being the most frequent, with three cases. Two cases presented papilloedema and another displayed retrobulbar optic neuropathy. A total of 62.5% were diagnosed with neurosyphilis, the presence of which was related with compromise of the optic nerve (p = 0.035). None of them gave positive for VDRL in cerebrospinal fluid and they were diagnosed by the presence of FTA antibodies together with high protein levels in cerebrospinal fluid, lymphocytic pleocytosis or intrathecal synthesis of antibodies. In the absence of uveitis, diagnosis was delayed by a mean time of 2.6 months (p = 0.047). All the patients, except one who required a vitrectomy, progressed favourably with intravenous antibiotic therapy. Conclusions. In cases of neuro-ophthalmological compromise, whether inflammatory or non-inflammatory, the physician must bear syphilis in mind as a potential causation in order to avoid delays in the diagnosis, since early well-tailored treatment can prevent permanent loss of sight(AU)
