Díaz Torres,Héctor M.; Sánchez Ruiz,Julieta; Martín Alfonso,Dayamí; Pérez Nellar,Jesús;
Revista Cubana de Medicina Tropical , 2008,
Abstract: background: the human t cell lymphotropic virus type i (htlv-i) is considered to be endemic in the caribbean area, where it is recognized as the etiologic agent of the tropical spastic paraparesis (tsp). in cuba, 0.037 % seroprevalence has been reported. objectives: to demonstrate the association of the htlv-i infection in a patient showing tropical spastic paraparesis and chronic proliferative knee synovitis. methods: the clinical diagnosis of spastic paraparesis and chronic proliferative knee synovitis was made. humoral and diagnostic imaging studies were performed to support the differential and positive diagnoses. elisa′s and western blot techniques were used for the detection of htlv-i antibodies. results: the htlv-i infection was confirmed by serologic studies. the symptoms and signs were compatible with those established in the who guidelines for the diagnosis of this disease. the case no. 33 with diagnosis of htlv-i infection in cuba was reported. conclusions: it was the first time that the association of tsp and joint manifestations was found in a cuban htlv-i infected patient.

Revista Cubana de Medicina Tropical , 2008,
Abstract: IINTRODUCCIóN: el virus linfotrópico de las células T humanas tipo I (HTLV-I) es endémico en la cuenca del Caribe, donde se reconoce como agente etiológico de la paraparesia espástica tropical. En Cuba se ha reportado una seroprevalencia de 0,037 %. OBJETIVOS: demostrar la asociación de la infección por HTLV-I en una paciente con paraparesia espástica tropical y sinovitis proliferativa de rodilla. MéTODOS: se estableció el diagnóstico clínico de paraparesia espástica y sinovitis proliferativa crónica de rodilla. Se realizaron estudios humorales e imagenológicos para sustentar los diagnósticos positivo y diferencial; se emplearon sistemas de ELISA y western blot para la detección de anticuerpos contra HTLV-I. RESULTADOS: los estudios serológicos confirmaron la infección por HTLV-I. Los síntomas y signos resultaron compatibles con la guía para el diagnóstico establecida por la Organización Mundial de la Salud y se hizo el reporte número 33 de la relación de individuos con infección por HTLV-I diagnosticados en Cuba. CONCLUSIONES: se presentó, por primera vez en una paciente cubana infectada por HTLV-I, la asociación de paraparesia espástica tropical con manifestaciones articulares.

Revista Cubana de Medicina Tropical , 2007,
Abstract: Se expusieron los resultados del dise o y la evaluación del diagnosticador DAVIH VIH-2, sistema ELISA indirecto dise ado para el pesquisaje de anticuerpos al VIH-2, que utiliza en su fase sólida un péptido sintético de la proteína de envoltura gp36 del VIH-2. La evaluación del desempe o del sistema se realizó utilizando paneles de referencia de la OMS y se determinó que la sensibilidad fue 100 %, la especificidad 99,81 %, la eficacia 99,81 % y la concordancia muy buena (índice kappa= 0,978). Las muestras de suero de 959 personas con resultados indeterminados o negativos a la confirmación de anticuerpos al VIH-1 (DAVIH-Blot) se evaluaron en el sistema DAVIH VIH-2. Resultaron reactivas al sistema 24 muestras, confirmándose la presencia de anticuerpos al VIH-2 en 6 de ellas. Estos resultados permitieron sugerir la introducción de este diagnosticador en el algoritmo de diagnóstico de la infección por VIH en Cuba. The results of the design and evaluation of DAVIH VIH-2 diagnosing system, an indirect Elisa for screening of HIV-2 antibodies, which uses a HIV-2 glycoprotein gp36 synthetic peptide in its solid phase, were exposed. In the system evaluation using WHO reference panels, 100 % sensitivity, 99,81 % specificity, 99,81% efficacy and very good concordance level (kappa = 0.978) were attained. Serum samples of 959 individuals with undetermined or negative results to the HIV-1 antibodies confirmation (DAVIH blot) were evaluated by the DAVIH VIH-2 system. Twenty four samples were reactive, six of which had confirmed HIV-2 antibodies. These results allowed recommending the introduction of this diagnostic kit in the HIV infection diagnosing algorithm in Cuba.

Abstract: objective: to determine the prevalence of human t-cell lymphotropic virus type i (htlv-i) infection among patients with lymphoproliferative disorders, as well as among their family members and sexual contacts, at two sentinel sites in cuba. methods: an analysis was conducted of all the patients with a presumptive diagnosis of hematological malignancies seen by the hematology departments of the hospital hermanos ameijeiras (hha), city of havana, and the hospital provincial comandante faustino pérez (hpcfp), matanza, cuba, in january 1996-january 1997. htlv-i seropositivity was determined by elisa and western blot, and infection was confirmed by polymerase chain reaction. the positive patients' family members and sexual contacts were also assessed. the z-test was used to compare proportions. results: seroprevalence of htlv-i infection in patients with lymphoproliferative disorders was 0.4% higher at the hpcfp than at the hha (6.1% versus 0.2%, p < 0.001). there were no significant differences in prevalence by age, sex, or skin color. of the 53 family members and sexual contacts studied, 8 (15.1%) were positive for htlv-i infection. conclusion: the prevalence of htlv-i in the study group was higher than previously found in cuba. the value of seroepidemiological surveillance through sentinel sites was confirmed.
