    La polineuropatia desmielinizante aguda (AIDP) es un desorden inmune que afecta el nervio perif茅rico produciendo lesi贸n axonal o miel铆nica. las infecciones respiratorias altas, gastrointestinales o los cuadros febriles inespec铆ficos usualmente preceden este caudro cl铆nico caracterizado por debilidad progresiva y disminuci贸n de reflejos miotendinosos. En el paciente con infecci贸n VIH la AIDP usulamnete aparece en el periodo de seroconversi贸n cuando el conteo de CD4 es mayor a 500 c茅lulas/uL. Se presume origen infecciosos a pesar de no existir un anticuerpo espec铆fico. reportamos dos casos de paciente con VIH y ADPI con resentaci贸n at铆pica. El primero con un conteo de CD4 menos a 100 c茅lulas/uL, el segundo en el contexto de s铆ndrome de reconstituci贸n inmunol贸gica (IRIS). Ambos pacientes tuvieron recuperaci贸n satisfactoria luego de tratamiento con inmunoglobulina intravenosa y suspensi贸n temporal del tratamiento antiretroviral respectivamente.210-214Acute inflammatory demyelinating polyneuropathy AIDP is an immune mediated disorder that affects the peripheral nerve reflected in myelin damage and sometimes in axonal loss. Upper respiratory infection, gas- trointestinal infection or nonspecific febrile processes are clinical entities that usually precede neurological symptoms represented by progressive weakness of the extremities and attenuation of tendinous reflexes. In the setting of HIV infection AIDP is a peripheral nerve disorder that usually occurs shortly after seroconversion when the CD4 count is higher than 500 cells/碌l. It is presumed to be immune mediated, although the offending antibody has not been identified yet. We report two clinical cases of atypical AIDP in the setting of HIV infection: The first with a T lymphocyte CD4 count lower than 100 cells /碌l and the second in context of immunologic reconstitution inflammatory syndrome IRIS. Both entities are uncommon phenomena. The patients recovered satisfactorily after receiving intravenous immunoglobulin and temporary cessation of antiretroviral therapy respectively

    El s铆ndrome de reconstituci贸n inmunol贸gica inflamatorio (SRII) en pacientes con infecci贸n por el virus de inmunodeficiencia humana (VIH), es una entidad cl铆nica rara caracterizada por un aumento de linfocitos T CD4+ (CLTCD4+) y disminuci贸n de la carga viral servir谩 del VIH, que aparece corto tiempo despu茅s de iniciar terapia antirretroviral de gran actividad (TARGA). Usualmente se manifiesta con un deterioro parad贸jico del estado del paciente secundario a una reactivaci贸n de procesos infecciosos oportunistas. Caso cl铆nico: hombre con diagn贸stico de toxoplasmosis cerebral en el curso de infecci贸n por VIH, quien posterior al inicio de la TARGA desarrollo coriorretinitis. El paciente experimento mejor铆a poco tiempo despu茅s de haber suspendido la TARGA y de administrar esteroides. Conclusi贸n: La incidencia del SRII ha aumentado en los pacientes VIH que cursan con alta carga antig茅nica y CLTCD4+ bajo. Su patofisiolog铆a genera incertidumbre debido a que los biomarcadores diagn贸sticos y pron贸sticos no se conocen del todo. El tratamiento propuesto lo constituye en algunos casos la suspensi贸n temporal de la TARGA con administraci贸n de esteroides, no obstante es necesaria la realizaci贸n de m谩s estudios.Caso clinico63-68Immune reconstitution inflammatory syndrome (IRIS) in context of severe immunosupression secondary to human immunodeficiency virus (HIV), is characterized by a dramatic rise of T lymphocyte CD4+ count in addition to a HIV viral load drop in, typically it is manifested by a paradoxical clinical impairment due to reactivation opportunistic of infectious processes previously under immune surveillance. A 36 years old male with cerebral toxoplasmosis in context of HIV infection developed chorioretinitis 8 weeks after commencing HAART. Workup laboratories only showed a marked T Lymphocyte CD4+ count increase with a HIV viral load lower than 40 copies/ml and other possible causes of chorioretinitis were excluded. After cessation of HAART and establishing corticosteroid therapy clinical improvement of this condition was documented. IRIS incidence has increased among AIDS patients especially with high antigenic burden and very low CD4 + T lymphocyte count. However its mechanism is still unclear due to biomarkers for diagnosis and prognosis are not completely known at all. In order to validate and refine diagnostic criteria and therapeutic approaches of IRIS more studies are needed

    Los pacientes con infecci贸n por VIH tienen una mayor incidencia de eventos cardiovasculares en comparaci贸n con la poblaci贸n general; los factores que contribuyen al incremento del riesgo de eventos cardiovasculares son la prevalencia de factores de riesgo cardiovascular tradicionales (FRCV), la infecci贸n por VIH que condiciona tanto un proceso de inflamaci贸n cr贸nica como alteraci贸n de la funci贸n endotelial y la exposici贸n a los antirretrovirales. Los factores que deben ser objeto de intervenci贸n son los FRCV tradicionales, en especial la alta tasa de fumadores entre este grupo de pacientes, la tamizaci贸n y tratamiento de HTA, el s铆ndrome metab贸lico y el acceso temprano a la terapia antirretroviral con medicamentos con mayor perfil de seguridad . Esta gu铆a pretende proveer informaci贸n y recomendaciones en el 谩mbito nacional acerca de la relaci贸n entre la infecci贸n por VIH/SIDA (S铆ndrome de Inmunodeficiencia Adquirida), uso de antirretrovirales y riesgo cardiovascular.Q1Art铆culo original73-91Patients with VIH infection have greater risk for cardiovascular diseases compared to general population. Risk factors that increase the frequency of cardiovascular events are: presence of cardiovascular traditional risk factors, chronic inflammation by HIV that impairs endothelial function and the exposure to antiretrovirals. The factors that should be the target for intervention are the traditional know cardiovascular factors such, especially high rate of smokers, screening and treatment for hypertension, metabolic syndrome and early access to HAART. The present guidelines provides information about the use of antiretrovirals in patients with HIV and its relation with cardiovascular risk

    Objetivos: Evaluar la frecuencia de alteraci贸n tiroidea y los factores asociados en los pacientes con VIH/SIDA de un hospital universitario en Colombia. Pacientes y M茅todos: Estudio tipo corte transversal de pacientes con VIH/SIDA durante el periodo de 2007 a 2008. Se registr贸 niveles hormonales, inmunol贸gicos, carga viral y tratamiento anti-retroviral. Resultados: En 636 pacientes la prevalencia de hipotiroidismo (TSH > 4,6 渭UI/mL) fue de 15,5% (100/636). El an谩lisis independiente demostr贸 relaci贸n significativa para el uso de nevirapina (RR 1,6; IC 95% 1,1 - 2,3) y estavudina (RR 1,5; IC 95%o 1 - 2,3). Conclusiones: La prevalencia de hipotiroidismo fue alta y se relacion贸 con el uso de nevirapina.59-63Introduction: The objective of this study was to evaluate the frequency of thyroid function alterations and its associated factors in a group of patients from a university hospital in Colombia. Methods: From June 2007 through June 2008, 636 HIV patients were followed in order to assess the relation of thyroid function with the use of HAART. Results: The overall prevalence of hypothyroidism (TSH > 4.6 渭UI/mL) was 15.5% (100/636). The association of hypothyroidism in the independent analysis showed significant relation only for the use of nevirapine (RR 1.6; CI 95% 1.1- 2.34) and stavudine (RR 1.5; CI 95%, 1 - 2.3). Conclusions: The prevalence of hypothyroidism was surprisingly high among the studied population
