Genetic Basis Identification of a NLR Gene, TaRGA5-like, That Confers Partial Powdery Mildew Resistance in Wheat SJ106.

Wheat powdery mildew is an important fungal disease that seriously jeopardizes wheat production, which poses a serious threat to food safety. SJ106 is a high-quality, disease-resistant spring wheat variety; this disease resistance is derived from Wheat-wheatgrass 33. In this study, the powdery mildew resistance genes in SJ106 were located at the end of chromosome 6DS, a new disease resistance locus tentatively named PmSJ106 locus. This interval was composed of a nucleotide-binding leucine-rich repeat (NLR) gene cluster containing 19 NLR genes. Five NLRs were tandem duplicated genes, and one of them (a coiled coil domain-nucleotide binding site-leucine-rich repeat (CC-NBS-LRR; CNL) type gene, TaRGA5-like) expressed 69-836-fold in SJ106 compared with the susceptible control. The genome DNA and cDNA sequences of TaRGA5-like were amplified from SJ106, which contain several nucleotide polymorphisms in LRR regions compared with susceptible individuals and Chinese Spring. Overexpression of TaRGA5-like significantly increased resistance to powdery mildew in susceptible receptor wheat Jinqiang5. However, Virus induced gene silence (VIGS) of TaRGA5-like resulted in only a small decrease of SJ106 in disease resistance, presumably compensated by other NLR duplicated genes. The results suggested that TaRGA5-like confers partial powdery mildew resistance in SJ106. As a member of the PmSJ106 locus, TaRGA5-like functioned together with other NLR duplicated genes to improve wheat resistance to powdery mildew. Wheat variety SJ106 would become a novel and potentially valuable germplasm for powdery mildew resistance.

Sociodemographic predictors associated with the spectrum of non-opportunist neuroretinal disease of non-infectious etiology in patients with HIV/AIDS: A scoping review.

BACKGROUND: Non-infectious retinal disease, even in the HAART era, continues to be one of the most common diagnoses in patients with HIV, with prevalences of up to 27% of cases. This study aims to characterize the association between demographic variables and their role. As a risk factor for the development of non-opportunistic non-infectious retinal disease in patients with HIV/AIDS. METHODS: An integrative review of the literature was carried out according to Arksey O'Malley's approach, based on the PICO methodology and following the PRISMA recommendations; An exhaustive search was carried out in databases of articles that were filtered using established criteria, with their extraction and analysis carried out qualitatively. RESULTS: Ocular manifestations from any cause develop from 35 years of age in patients with HIV/AIDS, with the highest risk for age-related macular degeneration over the fourth decade of life and for the development of neuroretinal disorder on the fifth decade of life; some studies report a slight tendency to diagnose macular degeneration in women and those who acquired AIDS through sexual contact; data contrasted with increased risk for diagnosing neuroretinal disorder in homosexual men who also use intravenous drugs, possibly due to oversampling in studies; non-Hispanic whites and African Americans were the races most commonly affected by neuroretinal disease; the means between the 11.3-14.5 years elapsed since the HIV diagnosis were more frequently associated with cognitive impairment and both in those with high or low CD4 counts, and in patients with high or low viral loads, neuroretinal disease without Statistically significant differences. Adherence and early initiation of HAART had a modest impact on the development of neuroretinal disease. DISCUSSION: Even in the HAART era, non-infectious neuroretinal disease and cytomegalovirus retinitis remain the most frequent ocular diagnoses, however, different studies argue an increase in age-related non-infectious retinal diseases in patients with HIV, theories that are may explain by the increase in life expectancy, the metabolic effects of HAART itself or the generalized pro-inflammatory state in this group of patients, it is essential to recognize this new diagnostic challenge in order to direct preventive efforts through the use of cost-effective sociodemographic risk predictors towards that technological tools for diagnosis and treatment can be targeted. CONCLUSIONS: HIV/AIDS patients who present at the ophthalmological consultation with the suggested sociodemographic predictors have a high risk of visual impairment due to non-infectious retinopathy, therefore prevention, diagnosis and treatment efforts directed at these diseases should be increased.

HCV microelimination in harm reduction centres has benefits beyond HCV cure but is hampered by high reinfection rates.

Background & Aims: Significant scale-up of treatment among people who inject drugs (PWID) is crucial to achieve WHO HCV elimination targets. We explored the impact of on-site HCV diagnosis and treatment on PWID in an externalised hepatology clinic at the biggest harm reduction centre (HRC) in Barcelona attending to a marginalised PWID population with ongoing high-risk practices. Methods: On-site HCV point-of-care testing was performed for diagnosis and treatment delivery. HCV-RNA was assessed at SVR12 (sustained virologic response at 12 weeks) and every 6 months. The programme included behavioural questionnaires at baseline and after treatment. Results: Between 2018 and 2020, 919 individuals were prospectively enrolled. Of these, only 46% accepted HCV screening. HCV-RNA+ prevalence was 55.7% (n = 234). Of the 168 (72%) individuals starting treatment, 48% were foreigners, 32% homeless, 73% unemployed, and 62% had a history of incarceration. At enrolment, 70% injected drugs daily and 30% reported sharing needles or paraphernalia. Intention-to-treat SVR12 was 60%; only 4% were virological failures, the remaining were either early reinfections (20%) or losses to follow-up (16%). The overall reinfection rate during follow-up was 31/100 persons/year. HIV coinfection and daily injection were associated with a higher risk of reinfection. Nonetheless, beyond viral clearance, antiviral therapy was associated with a significant reduction in injection frequency, risk practices, and homelessness. Conclusions: HCV treatment can be successfully delivered to active PWID with high-risk practices and has a significant benefit beyond HCV elimination. However, approaching this difficult spectrum of the PWID population implies significant barriers such as low rate of screening acceptance and high dropout and reinfection rates. Lay summary: People who inject drugs attending harm reduction centres represent the most difficult population to treat for hepatitis C. We show that hepatitis C treatment has a significant benefit beyond viral cure, including improving quality of life, and decreasing injection frequency and risk practices. However, intrinsic barriers and the high reinfection rates hamper the achievement of viral microelimination in this setting.

Sociodemographic predictors associated with the spectrum of non-opportunist neuroretinal disease of non-infectious etiology in patients with HIV/AIDS: a scoping review. / Predictores sociodemográficos asociados al espectro de enfermedad neurorretiniana no oportunista de etiología no infecciosa en pacientes con VIH/SIDA: revisión integrativa.

Epidemiology and outcome of HIV-infected patients admitted to the ICU in the current highly active antiretroviral therapy era.

PURPOSE: To describe the epidemiology of critical disease in HIV-infected patients during the current highly active antiretroviral therapy (HAART) era and to identify hospital mortality predictors. METHODS: A longitudinal, retrospective observational study was made of HIV-infected adults admitted to the ICU in two Spanish hospitals between 1 January 2000 and 31 December 2014. Demographic and HIV-related variables were analyzed, together with comorbidities, severity scores, reasons for admission and need for organ support. The chi-squared test was used to compare categorical variables, while continuous variables were contrasted with the Student's t-test, Mann-Whitney U-test or Kruskal-Wallis test, assuming an alpha level=0.05. Multivariate logistic regression analysis was used to calculate odds ratios for assessing correlations to mortality during hospital stay. Joinpoint regression analysis was used to study mortality trends over time. RESULTS: A total of 283 episodes were included for analyses. Hospital mortality was 32.9% (95%CI: 21.2-38.5). Only admission from a site other than the Emergency Care Department (OR 3.64, 95%CI: 1.30-10.20; p=0.01), moderate-severe liver disease (OR 5.65, 95%CI: 1.11-28.87; p=0.04) and the APACHE II score (OR 1.14, 95%CI: 1.04-1.26; p<0.01) and SOFA score at 72h (OR 1.19, 95%CI: 1.02-1.40; p=0.03) maintained a statistically significant relationship with hospital mortality. CONCLUSIONS: Delayed ICU admission, comorbidities and the severity of critical illness determine the prognosis of HIV-infected patients admitted to the ICU. Based on these data, HIV-infected patients should receive the same level of care as non-HIV-infected patients, regardless of their immunological or nutritional condition.

A wheat NBS-LRR gene TaRGA19 participates in Lr19-mediated resistance to Puccinia triticina.

Wheat leaf rust, caused by Puccinia triticina (Pt), is one of the most severe fungal diseases on wheat globally. Rational utilization of wheat leaf rust resistance (Lr) genes is still the best choice for control this disease. Wheat seedlings carrying Lr19 showed a high resistance phenotype to all Pt races in China. So far, all the cloned seedling Lr genes including Lr1, Lr10 and Lr21, encode protein with NBS-LRR domain. In this study, a wheat gene with NBS-LRR domain from previously established Lr19-resistance-related cDNA library was cloned and designated as TaRGA19. Full length of this gene was amplified by rapid amplification of cDNA ends (RACE). By blast against IWGSC wheat genome database, we have noticed that TaRGA19 was located on chromosome 2DS, which was different from Lr19 located on chromosome 7DL. Compared with susceptible Thatcher line, expression level of TaRGA19 was upregulated in wheat isogenic lines carrying Lr19 (TcLr19) after inoculation of Pt race THTS. By particle bombardment, TaRGA19-GFP fused protein was localized on plasma membrane of epidermal cells. Using virus-induced gene silencing (VIGS), TaRGA19-knockdown plants of TcLr19 showed reduced resistance and few sporulation phenotype upon Pt challenge. Further histological observation indicated that Pt hyphal growth at the infection sites was less suppressed in the TaRGA19-knockdown plants. In conclusion, we speculate this TaRGA19 gene was involved in the Lr19-mediated resistance to wheat leaf rust along with other components.

Métodos: Estudio observacional, transversal, analítico y descriptivo donde se evaluó a 123 pacientes con un cuestionario CEAT-VIH. Se realizó la recolección de datos en el programa Microsoft Excel y el análisis estadístico mediante el programa SPSS v.22. Resultados: Donde encontramos que la edad promedio de los todos los pacientes evaluados es 40.11 años. El tiempo de infección de los pacientes evaluados fue un promedio un año y 7 meses. El tiempo de tratamiento con el TARGA consto de un promedio de 20 meses. El 52 % (64 pacientes) de la población estudiada fue algún familiar del titular, ya sea esposa (o), hijo (a) o padres. El género que prevalece en la muestra es masculino con el 63.4 % (78 pacientes). Y la carga viral, el 77.2 % es indetectable (< 400 copias/ml). El grado encontrado fue una adecuada adherencia al TARGA, con una puntuación de 82.51 y al relacionar el grado de adherencia con las características socio-demográficas no son significativas. Pero si se encontró relación el grado de adherencia con la carga viral. Conclusión: La población estudiada tiene una adecuada adherencia al tratamiento antirretroviral y los 5 factores que mide el cuestionario: cumplimento del tratamiento, antecedentes de la falta de adherencia, interacción médico-paciente, creencias del paciente y estrategia para la toma de medicamentos, tienen muy buena influencia en la adherencia al TARGA.

Objective: To determine the associated factors and the degree of adherence to HAART in patients with HIV / AIDS at the PNP Central hospital "Luis N. Saenz" from October to December 2015. Methods: Observational, cross- sectional, analytical and descriptive study where 123 patients with a CEAT-HIV questionnaire were evaluated. Data collection was performed in the Microsoft Excel program and statistical analysis using the SPSS v.22 program.

Encefalitis por virus de inmunodeficiencia humana, reporte de un caso y revisión de tema / Encephalitis human immunodeficiency virus, a case report and review

En este artículo se presenta el caso de un paciente con diagnóstico histológico de encefalitis por virus de inmunodeficiencia humana - (VIH), con múltiples coinfecciones incluyendo oportunistas. Es un caso llamativo, pues claramente la incidencia de dicha enfermedad ha decrecido ostensiblemente en la era post terapia antiretroviral de gran efectividad (TARGA). Es un paciente masculino heterosexual de 63 años con conductas sexuales de riesgo, que ingresó a un hospital de cuarto nivel con síntomas respiratorios y durante su hospitalización se le diagnosticó VIH / SIDA estadio C3, múltiples infecciones tales como: hepatitis B, neurosífilis, criptococosis sistémica, toxoplasmosis cerebral, histoplasmosis cutánea, candidiasis y herpes oral; recibió tratamiento y falleció 27 días después por criptococosis diseminada. Se le practicó autopsia y se observó en sustancia blanca del sistema nervioso central numerosos nódulos microgliales, linfocitos perivascular y células gigantes multinucleadas sin formación de granulomas, característicos de la encefalitis por VIH. Este paciente es un ejemplo de la historia natural por VIH en estadío avanzado con compromiso del sistema nervioso central.

In this paper we describe the case of a patient with histological diagnosis of human immunodeficiency virus (HIV) encephalitis, which also had multiple co-infections. It is a striking case, because of the incidence of this disease has markedly decreased in the post Highly Active Antiretroviral Therapy HAART era. The patient was a heterosexual male of 63 years old engaged in risky sexual behavior, who was admitted to a reference hospital with respiratory symptoms. During hospitalization He was diagnosed with stage C3 HIV/AIDS, multiple infections such as Hepatitis B, Neurosyphilis, systemic cryptococcosis, cerebral toxoplasmosis, cutaneous histoplasmosis, oral herpes and candida infections; He received appropriate treatments for all of the above, however He died 27 days later by disseminated cryptococcosis. He underwent autopsy and in central nervous system in the white matter were observed numerous microglial nodules, perivascular lymphocytes and multinucleated giant cells without granuloma formation. These giant cells are characteristics of HIV encephalitis. This patient is an example of the natural history of HIV infection that progressed to an advanced stage of AIDS.

Caracterización de la mortalidad por sida en la provincia Sancti Spíritus. 1986-2011 / Characterization of the mortality by AIDS in the county Sancti Spíritus. 1986-2011

Fundamento: El sida es una de principales causas de muerte en pacientes jóvenes y en la provincia esta enfermedad ha tenido un aumento. Objetivo: Caracterizar la mortalidad por VIH/sida en Sancti Spíritus del 1986 al 2011. Metodología: Se realizó un estudio descriptivo, con análisis de información retrospectiva, que incluyó 90 fallecidos por esta causa, las variables incluyeron edad, sexo, años vividos con diagnóstico de VIH/sida, municipio de residencia, causa del fallecimiento, uso de tratamiento antirretroviral y grado de inmunodepresión. Resultados: Cabaiguán y Sancti Spíritus aportaron el mayor número de fallecidos, el sexo masculino y las edades de 21-40 fueron los más frecuentes, en los periodos de 1996-2000 y 2006-2010; la tendencia fue siempre ascendente. Alrededor de 70 de ellos tenían pocos años de infección por VIH y no utilizaron tratamiento, para un 77.8 %, fallecieron 26 antes de recibir Tratamiento Antirretroviral de Gran Actividad en 1996. Las causas de muerte fundamentales fueron: síndrome de desgaste, neumonía por Pneumocisty jeroveci, neurotoxoplasmosis y cryptosporidiasis Conclusiones: En el período se manifestó tendencia ascendente de la mortalidad en la provincia. El estado de inmunodepresión marcada y alto porcentaje de no uso de Tratamiento Antirretroviral de Gran Actividad que favoreció la aparición de enfermedades oportunistas causantes de las defunciones.

Background: The AIDS is one of main causes of death in young patients and in this county where this illness has had an increase. Objective: To characterize the mortality by HIV/AIDS in Sancti Spíritus from 1986 to 2011. Methodology: It was carried out a descriptive study, with retrospective analysis of the information that included 90 deaths by this cause, the variables included age, sex, lived years with the HIV/AIDS diagnose, residence municipality, causes of the death, use of antiretroviral treatment and immunodepression grade. Results: Cabaiguán and Sancti Spíritus contributed to the biggest number of deceases, the masculine sex and the ages from 21-40 were the most frequent, in the period from 1996-2000 and 2006-2010; the tendency was always upward. Around 70 of them had few years of infection for HIV and they didn't use treatment, from a 77.8%, 26 died before receiving Antiretroviral Treatment of Great Activity in 1996. The fundamental causes of death were: waste syndrome, pneumonia for Pneumocystis jeroveci, neurotoxoplasmosis and cryptosporidiosis. Conclusions: In the period it showed an upward tendency of the mortality in the county. The state of marked immunodepression and high percentage of no use of the Antiretroviral Treatment of Great Activity favored the appearance of opportunist illnesses causing the deceases.

Prácticas de autocuidado y la adherencia al TARGA en personas que viven con VIH en un hospital nacional de Lima / Self-care practices and adherence to TARGA in people living with HIV at a national hospital Lima

Objetivo: determinar la relación entre las prácticas de autocuidado y la adherencia al TARGA en personas que viven con VIH de un hospital nacional. Material y métodos: estudio cuantitativo, correlacional, de corte transversal, la muestra estuvo compuesta de 288 personas que viven con VIH; se elaboró un cuestionario de 37 preguntas sobre prácticas de autocuidado y adherencia al TARGA, las cuales fueron validadas a través de una juicio de expertos y una prueba piloto; posteriormente, se obtuvo un listado de personas que viven con VIH de la historia clínica. Resultados: La recolección de datos permitió obtener los resultados que muestran que las prácticas son inadecuadas en su mayoría (99,7 por ciento), solo presentan prácticas de autocuidado adecuadas 0,3 por ciento. El perfil de adherencia, en su mayoría, también son no adherentes en un 70,1 por ciento, mientras que 29,9 por ciento son adherentes. El coeficiente de correlación rho de Spearman (R=0,445) muestra una correlación significativa (p=0,000), la cual resultó positiva y de nivel medio, lo que significa que niveles bajos de prácticas de autocuidado se corresponden con niveles bajos de adherencia, y viceversa. Conclusiones: las prácticas de autocuidado y la adherencia al tratamiento del TARGA se encuentran relacionadas con la decisión personal de lograr la madurez en su propio autocuidado, esto quiere decir que los patrones del comportamiento están interactuados seg£n su estilo de vida.

Objetive: To determine the relation between the practices of auto care and the adherence to the TARGA in persons who live with HIV of a National Hospital. Material and Methods: quantitative Study, correlacional, of transverse court, sample of 288 persons who live with HIV; there was elaborated a questionnaire of practices of auto care and adherence to the TARGA of 37 questions, which were validated across one expertsÆ and a pilot test was realized and later obtained a personsÆ list through that they live with HIV of the clinical history. Results: The compilation of information allowed to obtain the results that show us that the practices are inadequate in the main with 99.7 percent, only they present suitable practices of auto care 0.3 percent. The profile of adherence in the main also adherents are not in 70.1 percent and 29.9 percent adherents. The coefficient of correlation Rho de Spearman (R=0.445) shows a statistically significant correlation (p=0.000), which turned out to be positive and of average level, which means that low levels of practices of auto care correspond with low levels of adherence and vice versa. Conclusions. The practices of auto care and the adherence to the treatment of the TARGA are associated with the personal decision to achieve the maturity in his own auto care; this wants to say that the bosses of the behavior are interacted according to his way of life.

Espectro de patógenos pulmonares en pacientes VIH+ en la era TARGA / Spectrum of pulmonary pathogens in HIV + patients in the HAART era

La infección por el Virus de Inmunodeficiencia Humana es un importante problema de salud pública a pesar del advenimiento de la terapia antiretroviral. Describir los patógenos pulmonares más frecuentes en pacientes VIH+ en la era del uso de terapia antirretroviral de gran actividad (TARGA). Se evaluaron 35 pacientes VIH+ que acudieron al Servicio de Neumonología y Cirugía de Tórax del Instituto Autónomo Hospital Universitario de Los Andes (Mérida, Venezuela). Se realizó evaluación clínica y fibrobroncoscopia con la finalidad de obtener muestras para cultivos cuantitativos bacteriológicos, micológicos y estudio anatomopatológico. Todos los pacientes mostraron síntomas respiratorios; sólo la disnea fue más frecuente en pacientes sin TARGA. Las alteraciones radiológicas no fueron significativamente diferentes entre ambos grupos de pacientes; sin embargo, el engrosamiento septal evidenciado en la TCAR (tomografía de alta resolución) de Tórax y la neumonía intersticial en las muestras histopatológicas fueron más frecuentes en pacientes que no recibían TARGA. El 72% de los pacientes tuvo cultivos bacteriológicos positivos, asociados con niveles bajos de CD4+ (p=0.02). El 37% mostró cultivos micológicos positivos, pero ningún paciente presentó serología positiva para los hongos cultivados del LBA. El 57% presentó evidencias histopatológicas de infección por P. jirovecci, generalmente asociada a coinfección con C. albicans y/o H. capsulatum. A pesar del uso de terapia antiretroviral, las patologías pulmonares infecciosas siguen siendo causa frecuente de morbilidad en pacientes infectados con el VIH en Venezuela.

HIV infection is an important public health problem despite the use of antiretroviral therapy. To determine the pathogens in a group of HIV+ patients with lung infections in the era of current high activity anti-retroviral therapy (HAART). Thirty five patients who consulted to the Pulmonary and Thoracic Surgery Department of the University Hospital of Los Andes (Mérida, Mérida state, Venezuela) were evaluated. Clinical evaluation and flexible bronchoscopy were done to obtain samples for quantitative bacterial culture, mycological culture and anatomopathologic evaluation. All patients showed respiratory symptoms, but dyspnea was more frequent in patients not receiving HAART. Radiologic findings were not different between the two groups of patients although septal thickening in High Resolution Computed Thoracic Tomography (HRCT) and interstitial pneumonia in histopathologic samples were more often found in patients not receiving HAART. 72% of had positive bacterial cultures and these were associated with low CD4+ count (p = 0.02). 37% of patients showed positive my cological culture, although none of them showed positive serology for any of the fungi cultured from bronchoalveolar lavage. 57% of patients showed histopathologic evidence of P. jirovecci infection, generally associated with confection by C. albicans and/or H. capsulatum. Despite the use of antiretroviral therapy, pulmonary infectious diseases continue to be a major cause of morbidity among HIV infected patients in Venezuela.

Múltiples infecciones oportunistas concurrentes al sistema nervioso central en paciente VIH positivo y su respuesta al TARGA: reporte de un caso / Multiple concurrent central nervous system opportunistic infections in an HIV-positive patient and his response to HAART: a case report

En el contexto de una severa inmunodepresión existe una marcada dificultad para hacer diagnóstico definitivo de las infecciones oportunistas que son causa principal de morbilidad y mortalidad. La presencia de infecciones del SNC durante la evolución del paciente con VIH, es frecuente, siendo menos habitual la presencia múltiple y concurrente de éstas, pues tal situación somete a los pacientes a peor pronóstico. Por este motivo se muestra el estudio de un paciente que presentó múltiples infecciones oportunistas en el SNC, quien tras iniciar y continuar el TARGA mostró buena evolución. Caso clínico: varón de 51 años con antecedentes de alcoholismo que acude al hospital con s¡ndrome de hipertensión endocraneana. Es diagnosticado de meningitis criptocócica e infección por VIH estadio C sin TARGA. Durante el tratamiento se evidenci ademas infecciones oportunistas concurrentes, como meningitis tuberculosa, leucoencefalopatia multifocal progresiva y toxoplasmosis cerebral; conjuntamente presentó síndrome inflamatorio de reconstitución inmunológica (IRIS). El paciente al iniciar y mantener el TARGA se recuperó ¡ntegramente y manifestó buena evolución, actualmente es tratado ambulatoriamente y no se ha complicado. Interpretación: los episodios múltiples y concurrentes de infecciones oportunistas del SNC descritos as¡ como el IRIS, generalmente inducen a los pacientes a mal pronóstico, sin embargo, son pocos los casos que se recuperan copiosamente y muestran buen pronóstico. Este es un caso particular de recuperación después de seguir el TARGA correctamente. Se describe este reporte por su importancia para valorar una apropiada adherencia al TARGA.

In the context of severe immunosuppression, there is a marked difficulty in making a definitive diagnosis of opportunistic infections, which are leading causes of morbidity and mortality. The presence of CNS infections during the evolution of HIV patients is common, less common being multiple and concurrent presence of these. This situation undergoes patients with poor prognosis. For this reason we report the case of a patient who developed multiple opportunistic infections in the CNS, who after HAART initiation and continuation showed good performance. Clinical case: 51 year old male with a history of alcoholism, was admitted to hospital with intracranial hypertension syndrome. He was diagnosed with cryptococcal meningitis and HIV infection stage C without HAART. During treatment also showed concurrent opportunistic infections such as TB meningitis, progressive multifocal leukoencephalopathy and cerebral toxoplasmosis, jointly presented immune reconstitution inflammatory syndrome (IRIS). The patient, initiating and maintaining HAART, fully recovered and showed good performance. Currently he is treated as an outpatient and has no complications. Interpretation: The multiple concurrent episodes of opportunistic infections of the CNS described, as well as the IRIS, generally induce poor prognosis in patients. However, there are few cases that improve and show good prognosis. This is a particular case of recovery after HAART follow correctly. We describe this report because of its importance in assessing adherence to HAART.

Respuesta de la terapia antirretroviral en niños con infección por VIH-1. Corte Transversal / Response of antiretroviral therapy in children with HIV-1 infection. Cross-cutting

En el 2003 se inició el Tratamiento Antirretrov iral de Gran Act ividad (TARGA) por parte de la Secretaria de Salud de nuestro país. El seguimiento de estos pacientes se hac ía clí nicamente y con exámenes de laboratorio como hemograma y quím ica Sanginea, del conteo de CD4 se inicio en el 2005 al igual que la carga viral (CV), esta ultima de modo muy irregular. Neuroestudio, inicia en el 2009 con la disponibilidad permanebte de exámenes de CD4 y CV. Nuestro objetivo fueron identificar las respuestas terapeutica de los niños(a) con infección del VIH-1 tratado en el Centro de atención integral del Hospital Nacional del Dr. Mario Catarino Rivas entre el 2009 y el 2011; realizando un análisis descriptivo de la situación clínica, inmunológica y virológica de los niños(as) en tratamiento antirretroviral. utilizamos la Clasificación de CDC para la valoración clínica e inmunológica. Consideramos no detectable la CV que es menor de 50 copias/mi a los 6 meses de iniciado el tratatamiento antirretroviral por el método aplificación por RT-PCR (Abbott Real Time m2000rt). Se analizaron 338 expedientes, encontrando una eficacia terapéutica total del 80.2%. El esquema terapeutico de segunda línea sin falla terapéutica. La causa mas frecuente de falla fue la mala adherencia en un 73.9% y por resistenci a en un 10.1%. En conclusión la adherenci a es un factor importante para mantener la eficac ia terapéutica, aunque en nuestr o estudio no resultó estadísticamente significativo...(AU)

Efectos adversos y uso de antirretrovirales en el centro de atención integral VIH-Sida pediátrico del Hospital Nacional Dr. Mario Catarino Rivas / Adverse effects and use of antiretrovirals at the comprehensive pediatric HIV-AIDS center at the Dr. Mario Catarino Rivas National Hospital

En la tercera dé cada de la infecci ón por VIH, las nuevas terapias antirretrovirales han transformado la enfermedad de mortal a crónica. La realidad actual es reconocer que el prin- cipal y único enemigo del VIH es la preven- ción. Los ni ños infectados por VIH tambi én se han beneficiado de los avances en los conocimientos de la propia infecci ón, t écni cas diagnó sticas y de los tratamientos anti - rretrovirales del momento, igual que los adultos. Desde 1996, los niños infectados por el virus de la inmunodeficiencia humana reci ben tratamientos antirretrovirales denomina dos de gran actividad (TARGA). Se realiz ó un estudio Retrospectivo, anal ítico, longitudinal de dichos efectos en los pacientes atendidos en el Cen tro de Atenci ón integral (CA Í) del Hospital Nacional Dr. Mario Catarino Rivas de San Pedro Sula, en el periodo comprendido desde Enero del añ o 2000, hasta Noviembre del 2010, con una poblaci ón de 406 pacientes los cuales recibieron TARGA en nuestro hospital...(AU)

Response to first line HAART using CD4 cell counts: experience in a University Hospital in Kingston / Respuesta a la terapia TARGA de primera línea usando conteos CD4: experiencia en el Hospital Universitario en Kingston

OBJECTIVES: To assess the extent to which the current practice for first line therapy concurs with the recommended guidelines and to examine the response of treatment naïve patients to first line Highly Active Antiretroviral Therapy (HAART) at the University Hospital of the West Indies, using CD4 cell counts. METHODS: Over a three-month period, a cross-sectional study design was instituted and data were collected on all patients on HAART at the University Hospital ofthe West Indies (UHWI) outpatient HIV clinic. Information was collected by reviewing patient medical records using data collection sheets. The data obtained from the medical records included: age, gender, date of diagnosis of HIV, date at which HAART was commenced, CD4 cell counts prior to the commencement of antiretrovirals, the initial HAART regimes and subsequent CD4 cell counts. RESULTS: A total of 165 persons who met the criteria of being on HAART therapy were enrolled in the study. The average time span between diagnosis of HIV and commencement of antiretroviral therapy was 1.92 years and the range for this was 0 to 12.29 years. The average CD4 count prior to initiation of HAART was 186 cells/mm³. The most common regime used at the UHWI for first line therapy was combivir and efavirenz, n = 78 (47.3%), followed by combivir and nevirapine, n = 29 (17.6%). The average difference between the initial CD4 count prior to the initiation of HAART and first repeated CD4 count was 102 cells/mm³. The mean time between the first and repeated CD4 cell counts was 376 days. CONCLUSION: The recommended guidelines were adhered to for the majority of patients initiated on antiretrovirals at the UHWI. The treatment outcomes achieved at the UHWI were similar to those achieved in developed countries. This gives substantial evidence in support of international efforts to make antiretroviral therapy available in developing countries.

OBJETIVOS: Evaluar hasta que punto la práctica actual de la terapia de primera línea concuerda con las normas recomendadas y examinar la respuesta al tratamiento por parte de los pacientes nunca antes sometidos a la terapia antiretroviral altamente activa, (TARGA) en el Hospital Universitario, usando conteos de células CD4. MÉTODOS: Por un periodo de tres meses, se instituyó un diseno de estudio transversal, y se recogieron datos de todos los pacientes sometidos a TARGA en la clínica de VIH para pacientes externos en el Hospital Universitario de West Indies (UHWI). La información fue obtenida revisando las historias clínicas de todos pacientes, usando hojas de recogida de datos. Los datos obtenidos de las historias clínicas incluían: edad, género, fecha de diagnóstico de VIH, fecha de comienzo de TARGA, conteo de células CD4 antes del comienzo de los antiretrovirales, los regimenes iniciales de TARGA y los subsecuentes conteos de células CD4. RESULTADOS: Un total de 165 personas que satisfacían los criterios de la terapia TARGA fueron enroladas en el estudio. El tiempo promedio que medió entre el diagnóstico de VIHy el comienzo de la terapia antiretroviral fue 1.92 anos, en tanto el rango para esta fue de 0 a 12.29 anos. El conteo promedio de conteo de CD4 antes del comienzo de TARGA fue 186 células/mm3. El régimen más común usado en UHWIpara la terapia de primera línea fue combivir y efavirenz, n = 78 (47.3%), seguido por el combivir y nevirapine, n = 29 (17.6%). La diferencia promedio entre el conteo inicial de CD4 antes del comienzo de TARGA y elprimer conteo repetido de CD4 fue 102 células/mm3. El tiempo promedio entre los primeros conteos CD4 y los repetidos fue 376 días. CONCLUSIÓN: Se siguieron las normas recomendadas en relación con la mayoría de los pacientes iniciados en el tratamiento con antiretrovirales en UHWI. Los resultados del tratamiento logrados en UHWI fueron similares a los logrados en los países desarrollados. Esto ofrece sólidas evidencias en apoyo a los esfuerzos internacionales por poner la terapia antiretroviral a disposición de los países en vías de desarrollo.
