ABSTRACT

El virus chikungunya (CHIKV) es un Alfavirus causante de la fiebre chikungunya (CHIKF). En Venezuela, una región desprovista de inmunidad contra CHIKV y con presencia de Aedes aegypti y Aedes albopictus, el primer caso importado fue reportado por las autoridades sanitarias en junio de 2014. Por la relevancia del hecho, se analizaron 94 muestras de pacientes febriles que acudieron a los centros de salud públicos y privados del estado Aragua entre enero y diciembre de 2014, mediante la detección de los fragmentos de los genes nsP4 (Alfavirus) y E1 (CHIKV) utilizando técnicas moleculares, como Transcripción Reversa acoplada a Reacción en Cadena de la Polimerasa (RT-PCR) y/o secuenciación nucleotídica. Los resultados indicaron positividad en 19,2 % de las muestras analizadas. Se vieron afectados pacientes con edades entre 6 y 66 años, con predominio del sexo femenino (12/18). Clínicamente, todos los pacientes positivos a CHIKV manifestaron signos y síntomas asociados a CHIKF, tales como fiebre (18/18), artralgia (18/18) y erupción (16/18), entre otros. A pesar de que la positividad puede considerarse baja con relación a lo reportado en otras comunidades, este estudio representa el primer reporte local de detección molecular de CHIKV en Venezuela (estado Aragua) durante el año 2014.


Chikungunya virus is an Alphavirus that causes chikungunya Fever (CHIKF). In Venezuela, a region devoid of immunity against CHIKV and presence of Aedes aegypti and Aedes albopictus. The first imported case was reported by health authorities in June 2014. The relevance of the fact, 94 samples of febrile patients who came to the centers of public and private health Aragua state between january and december for detection of the nsP4 (Alphavirus) and E1 (CHIKV) fragments were analyzed by molecular techniques (Reverse Transcriptase Polymerase Chain Reaction and/or nucleotide sequencing). The results showed 19.2 % of positivity by CHIKV. Clinically all CHIKV positive patients showed signs and symptoms related with CHIKF, such as fever (18/18), arthralgia (18/18) and rash (16/18), among others. Were affected patients between the ages of 6 and 66 years with a predominance of the female sex (12/18). Although the positivity may be considered low compared to those reported in other communities, this represents the first local report of molecular detection of CHIKV in Venezuela (Aragua state) during 2014.

ABSTRACT

Linfoma não-Hodgkin é uma das complicações oncológicas mais freqüentes em portadores da Síndrome da Imunodeficiência Adquirida (AIDS). Em outros países, após a introdução da terapia anti-retroviral de alta atividade (HAART), a queda na incidência dos linfomas agressivos sistêmicos ficou aquém das expectativas, embora a sobrevida destes pacientes tenha triplicado. No Brasil, pouco se conhece a respeito do comportamento clínico e da sobrevida dos pacientes com linfoma e AIDS na era pós-HAART. O objetivo deste estudo foi avaliar retrospectivamente 25 pacientes com linfoma e AIDS, tratados com a associação de quimioterapia e HAART. Em concordância com a literatura, a maior parte dos pacientes era do sexo masculino - 20 (80 por cento), com mediana de idade de 39 anos. Houve predomínio do subtipo histológico Difuso de Grandes Células B - 13 (52 por cento), de pacientes em estádios avançados - 15 (60 por cento), com envolvimento extranodal - 22 (88 por cento) e com sintomas B - 18 (72 por cento). O diagnóstico prévio de AIDS observado em 14 (56 por cento) foi superior em nossa casuística em relação ao descrito por outros autores. Cinqüenta e dois por cento dos pacientes obtiveram RC, com SLD e SG em três anos de 54 por cento e 42 por cento, respectivamente e mediana de SG de 15 meses. Toxicidade hematológica e infecções foram freqüentes, porém nenhum óbito foi relacionado à sua ocorrência. Concluímos que o tratamento combinado com quimioterapia e HAART é factível em pacientes brasileiros, podendo propiciar uma sobrevida global similar à descrita por alguns grupos internacionais, com um perfil aceitável de toxicidade.


Non-Hodgkin lymphoma is one of the most frequent oncologicalcomplications in patients with the Acquired Immune-DeficiencySyndrome (AIDS). In other countries, after the introduction of the Highly Active Antiretroviral Therapy (HAART), the drop inthe incidence of systemic aggressive lymphomas was belowexpectations, although the survival of these patients rose. InBrazil, little is known about the clinical behavior and survival ofthe patients with lymphoma and AIDS in the post-HAART era.The aim of this study was to retrospectively evaluate 25 patientswith lymphomas and AIDS, treated with the combination ofchemotherapy and HAART. In agreement with the literature mostof the patients were male (20 patients - 80%) with a median ageof 39 years. We observed a predominance of the Diffuse Large BCell Lymphoma subtype (13 patients - 52%), advanced stage(15 patients - 60%), with extra-nodal disease (22 patients - 88%)and B symptoms (18 patients - 72%). Previous AIDS diagnosiswas present in 14 patients (56%), higher than that reported inother series. Fifty-two percent achieved CR, the estimatedprobability of overall survival and disease-free survival at 3years were 54% e 42%, respectively. The median overall survivaltime was 15 months. Hematological toxicity and infections werefrequently observed, but no toxicity-related deaths were seen.Therefore we conclude that the combined chemotherapy-HAARTtreatment is feasible in Brazilian patients and can provide similaroverall survival than that described for some internationalgroups, with an acceptable toxicity profile.
