Economic analysis of an educational human security model in southwestern bateyes of the Dominican Republic / Análisis económico de un modelo educativo de seguridad humana en los bateyes del suroeste de la República Dominicana

Objetivos: realizar un análisis económico para evaluar los costos de una intervención educativa, utilizando los principios de un modelo de seguridad humana en Bateyes del suroeste de la República Dominicana. Métodos: se consideraron cuatro recursos de intervención, incluyendo la capacitación del personal, los incentivos mensuales, la supervisión de las actividades de campo y el costo total asociado al tratamiento anual de la diarrea aguda. El gasto se comparó entre el programa estándar de atención (Batey Control) y la intervención con el modelo de seguridad humana (Batey Caso). Resultados: el ahorro del costo total anual para el Ministerio de Salud de República Dominicana asociado con la reducción de la incidencia de episodios de diarrea aguda fue de US$252,399. Si se extrapolan a los 300 Bateyes de República Dominicana, se podría ahorrar aproximadamente US$75 millones en prevención de enfermedades infecciosas. Conclusiones: el modelo de seguridad humana luce ser un método eficaz para mejorar el conocimiento sobre la prevención de enfermedades y aumentar el empoderamiento de la comunidad para la movilización de recursos. Aplicada a otros entornos, la intervención podría tener una incidencia beneficiosa en las poblaciones de refugiados e indocumentados bajo el impacto de la violencia estructural.

Objectives: To conduct an economic analysis to evaluate the costs of an educational intervention, using the human security model, and potential sources of economic benefits, in Southwestern Bateyes in the Dominican Republic. Methods: Four intervention resources were considered, including staff training, monthly incentives, supervision of field activities, and total cost associated with annual treatment for acute diarrhea. The expenditure was compared between the standard program of care and the intervention using the human security model. Results: The total annual cost saving to the Dominican Republic Ministry of Health, associated with reducing the incidence of acute diarrhea episodes, was US$252,399. If this is extrapolated to the 300 Bateyes of the Dominican Republic, the Ministry of Health could save approximately US$75 million in infectious disease prevention by implementing this intervention model in these isolated rural communities. Conclusions: The educational intervention, which incorporated a human security approach, appeared to be an effective method to enhance knowledge about disease prevention and to increase empathy among community members for resource mobilization and local empowerment. Applied to other settings, the intervention could have a beneficial impact on refugee and undocumented populations under the

Actitud de los estudiantes en tres facultades de odontología en Santiago de Cali, Colombia, frente a pacientes con VIH / Atitude dos estudantes em três faculdades de odontologia em Santiago de Cali, Colômbia, frente a pacientes com HIV / Attitudes of students at three dental schools in Santiago de Cali, Colombia, toward HIV+ patients

Objetivos: Conocer la actitud de estudiantes de odontología de Cali respecto del manejo de personas con diagnóstico de VIH/SIDA. Método: Estudio observacional descriptivo mediante aplicación de una encuesta aplicada en 1.173 estudiantes de tres facultades de odontología de Cali, clasificados en tres grupos (preclínica, clínica inicial y clínica final). Resultados: participó un 63,4 por ciento; 50 por ciento tenía menos de 20 años, 68 por ciento mujeres. 92 por ciento solteros y 82 por ciento católicos. Se encontró actitud positiva entre 86 por ciento y 92 por ciento, la disposición de atender pacientes fue más favorable en preclínica (p=0.03). Aunque 88,7 por ciento mostró disposición de atender pacientes VIH+; entre los que pensaban que sería difícil hacerlo para su personal auxiliar, se encontró 33 por ciento de estudiantes con probabilidad de hacerlo, (p= 0.03). Cuando se interrogó sobre conocimientos acerca del VIH/SIDA, 66,7 por ciento (clínica final) y 82,2 por ciento (preclínica) percibían que no habían recibido entrenamiento previo (p<0,001). Conclusiones: Se evidenció que la intención de atender pacientes VIH+ era similar a lo reportado en otros países americanos e Irlanda. Los estudiantes necesitan recibir un mejor entrenamiento con el fin de disminuir sus temores y mejorar su actitud para atenderlos.

Objective: To know attitude of students at three dental schools in Santiago de Cali, Colombia, toward HIV+ patients. Methods: This is a cross-sectional study with using a questionnaire to 1173 invited to attend students from three dental schools in Cali. Students were classified in three groups (Pre-clinic: semester I-IV; initial clinic: V to VII and last clinical: VIII to X). Results: Participation rate was 63.4 percent. 50 percent under 20 years old, 68 percent female, 92 percent single, and 82 percent Catholics. Between 86 percent and 92 percent had positive attitudes; when asked about their willingness to care patients being more favorable preclinical students (p=0.03). Although, 88.7 percent of all students showed a willingness to address HIV patients. Among those who believed that it would be difficult for assistant staff to accept treating such patients there was a 33 percent chance of doing so (p=0.003). When we asked about training to manage, between 67 percent (clinical) and 82 percent (preclinical) perceive not receiving any. Conclusions: The intention to dental care was similar to that reported in the other American countries, and Ireland. Dental students need better training, because they do not perceived adequate training, to reduce their fear and increase positive attitudes to care for HIV/AIDS patients.

Conclusões: Foi evidenciado que a intenção de atender pacientes HIV+ era similar ao reportado em outros países americanos e Irlanda. Os estudantes necessitam receber um melhor treinamento com a finalidade de diminuir seus temores e melhorar sua atitude para atendê-los.

VIH y vulnerabilidad: una comparación de tres grupos en Cali, Colombia / HIV and vulnerability: a comparison of three groups in Cali, Colombia

OBJETIVO: determinar las características socio-demográficas, comportamientos de riesgo para VIH/Sida y presencia de VIH en tres grupos de participantes de diferentes grupos socio-económicos en Cali. METODOLOGIA: entre 2005 y 2007, Durante campañas de búsqueda activa focal integral de VIH, 4055 participantes dieron voluntariamente su consentimiento informado, respondieron un cuestionario estructurado, recibieron asesoría de VIH pre-prueba y post-prueba, así como prueba para diagnóstico presuntivo de VIH. Los participantes fueron agrupados en tres categorías: personas de bajo nivel socio-económico, baja escolaridad y alto desempleo (N1=1217); trabajadores empleados con escolaridad técnica-superior y de estrato medio-alto (N2=899); y estudiantes de universidades de carácter privado, de estrato medio-alto (N3=1939). Se determinaron características socio-demográficas, comportamientos sexuales y auto percepción de conocimientos sobre VIH. Análisis estadístico: uso de Chi-Cuadrado y prueba de muestras independientes t-student, significancia<0.05 e intervalos de confianza al 95%. RESULTADOS: prevalencia global de VIH 0.62%; para el grupo N1 la prevalencia fue 1.97%, mayor que en los otros grupos (p<0.0001). CONCLUSIONES: una alta prevalencia de VIH en el grupo N1 fue evidente, junto con una historia previa más frecuente de Enfermedad de Transmisión Sexual (ETS) y pobre auto-percepción de conocimientos sobre VIH, destacando la necesidad de fortalecer las estrategias de prevención y tamizaje de ETS y VIH dirigidas a este grupo.

OBJECTIVE: to identify socio-demographical characteristics and risk behaviors for HIV /Aids and HIV status in three groups of participants from different socio-economic background in Cali. METHODOLOGY: between 2005 and 2007, an active surveillance campaigns was done and included 4055 voluntary participants who gave informed consent, answered a structured questionnaire, and received pre- and post-test counseling and HIV testing. The participants were grouped in three categories: a total of 1217 from low socio-economic status (lse), with low education and high unemployment (N1), 899 employed workers with technical-professional schooling and upper-middle socio-economic status (N2), and 1939 students of private universities and upper-middle socio-economic status (N3). Socio-demographic characteristics, sexual behaviors and HIV knowledge self-perception were assessed. Statistical analyses: Chi Square, and independent T tests with significance <0.05, 95% confidence intervals. RESULTS: overall prevalence of HIV was 0.62%; in the N1 group prevalence was 1.97%, significantly higher than in the other two groups, (p<0.0001). CONCLUSIONS: a higher prevalence of HIV in the N1 (lse) group was evident, along with a more frequent history of previous Sexual Transmision Disease (std), and poorer self-perception of HIV knowledge, highlighting the need to strengthen std and HIV prevention and testing strategies targeting this group.

Dominican Children with HIV not Receiving Antiretrovirals: Massage Therapy Influences their Behavior and Development.

Forty-eight children (M age = 4.8 years) infected with HIV/AIDS and living in the Dominican Republic were randomly assigned to a massage therapy or a play session control group. The children in the massage therapy group received two weekly 20-min massages for 12 weeks; the children in the control group participated in a play session (coloring, playing with blocks) for the same duration and length as the massage therapy group. Overall, the children in the massage therapy group improved in self-help abilities and communication, suggesting that massage therapy may enhance daily functioning for children with HIV/AIDS. Moreover, the HIV infected children who were six or older also showed a decrease in internalizing behaviors; specifically depressive/anxious behaviors and negative thoughts were reduced. Additionally, baseline assessments revealed IQ equivalence below normal functioning for 70% of the HIV infected children and very high incidences of mood problems (depression, withdrawn) for 40% of the children and anxiety problems for 20% of the children, suggesting the need for better monitoring and alternative interventions in countries with limited resources to improve cognition and the mental health status of children infected with HIV/AIDS.

Psychosocial and Clinical Characteristics and Psychiatric Co-morbidity Among Men and Women with HIV/AIDS under Medical Treatment at a Tertiary Health Care Center in Cali, Colombia

Introduction: Better understanding of psychosocial and health care needs of complex HIV/AIDS patients may facilitate disease management and virologic control. Objectives: To examine the behavioral, psychosocial, and co-morbid characteristics of HIV/AIDS illness in men and women being followed at a tertiary health care center in Colombia. Methods: A sample of HIV+ patients, 114 men and 29 women, was selected for review of clinical records. Results: Men were older (40 vs. 32 yrs.) and more likely to be employed (83 vs. 50%). Of those reporting sexual preference, 33% of men and 100% of women indicated being heterosexual. A higher percentage of men (34%) had CD4 count < 200 cells/mm2 when compared with the women (21%). More men than women had opportunistic infections (75 vs. 48%) and more men tended to be on complex medication regimens (68 vs. 48%). Viral load data was available for 53% of the cases, half of which had > 400 copies/ml. Only 40% of patients attended every scheduled 3-month visit. Less than one-quarter (22%) of the sample was diagnosed by a psychiatrist with a mental disorder and only a small proportion (one-fifth) had a psychiatric follow-up. Conclusions: Our study reveals several important findings among this sample of HIV patients attending a tertiary care private hospital in Cali: (1) the epidemic is rising among women, (2) undetected and under-treated psychiatric illness is highly prevalent, and (3) adherence to scheduled clinical visits is low among patients with a viral load >400 copies/ml. Thus, integrating psychosocial care with behavioral interventions to improve adherence is warranted to counteract these critical issues. An important weakness of this study was that clinical records did not include complete documentation of all variables...

Introducción: Una mejor comprensión de las necesidades psicosociales y de salud de pacientes con VIH/sida de mayor complejidad puede facilitar su manejo y control virológico. Objetivo: Estudiar las características de comportamiento, psicosociales y de comorbilidad en la enfermedad por VIH/sida en hombres y mujeres de un centro de atención nivel tres en Colombia. Método: Revisión de una muestra de pacientes con VIH+ de 114 hombres y 29 mujeres y de sus historias clínicas. Resultados: Los hombres eran de mayor edad (40 vs. 32 años) y estaban empleados (83% vs. 50%). En los que reportaron preferencia sexual, 33% de los hombres y 100% de las mujeres refirieron heterosexualidad. Un mayor porcentaje de hombres (34%) que de mujeres (21%) tuvo un recuento de CD4 <200 células/mm2. Más hombres tenían infecciones oportunistas (75% vs. 48%) y estaban en tratamientos médicos de mayor complejidad (68% vs. 48%). Datos de carga viral estaban disponibles en el 53% de los casos. Solamente 40% asistieron a cada una de las citas trimestrales. El 22% tenía un diagnóstico de enfermedad mental realizado por un psiquiatra, y sólo una quinta parte, seguimiento por psiquiatra. Conclusiones: Nuestro estudio revela tres hallazgos importantes para la población que acude a un hospital privado de nivel tres en la ciudad de Cali: (i) la epidemia está aumentando en mujeres, (ii) la enfermedad psiquiátrica no detectada y no tratada es altamente prevalente y (iii) la adherencia a las visitas programadas fue baja en los pacientes con carga viral >400 copias/ml. Por lo tanto, para mejorar adherencia es prioritario integrar el cuidado psicosocial con las intervenciones sobre el comportamiento y así controlar estos críticos aspectos...

HIV/AIDS knowledge and health-related attitudes and behaviors among deaf and hearing adolescents in southern Brazil.

HIV/AIDS knowledge and health-related attitudes and behaviors among deaf and hearing adolescents in southern Brazil are described. Forty-two deaf students attending a special nonresidential public school for the deaf and 50 hearing students attending a regular public school, ages 15-21 years, answered a computer-assisted questionnaire. (There was simultaneous video translation of questions to Brazilian Sign Language.) A branched decision-tree structure was used to determine level of sexual experience and hearing status. Deaf participants scored lower on HIV/AIDS knowledge, demonstrating a need to improve school-based instruction and develop campaigns tailored to this group's requirements. Though the hearing students reported more sexual activity than the deaf students, no other significant differences were found in health-related attitudes and behaviors. Two findings of concern are the high rate of sexual abuse reported by deaf participants and the large number of deaf adolescents reporting having a friend with AIDS.

The relationship between nutritional and sociodemographic factors and the likelihood of children in the Dominican Republic having a BCG scar.

OBJECTIVES: To critically assess the prevalence among schoolchildren 6 to 9 years of age throughout the Dominican Republic of a bacille Calmette-Guérin (BCG) vaccination scar, and to examine the relationship between nutritional and sociodemographic factors and the likelihood of having a BCG scar. METHODS: This correlational study used the database of the Second National Census on Height and Weight of Elementary School First Grade Students, which was conducted in the Dominican Republic August 2001-May 2002, to provide a critical assessment of BCG coverage nationwide. The Census information for the children included the presence of BCG scar, their nutritional status, and basic demographic data. We developed a new sociodemographic indicator, the "Rosa Index," to examine the potential influence of poverty and other environmental characteristics on scar presence. We used logistic regression models to predict the presence of a BCG scar. RESULTS: An overall BCG scar prevalence of 55.3% (85,644/154,887) was found. Malnourished children were less likely to have a BCG scar than were children with adequate nutritional status (odds ratio = 0.91; 95% confidence interval: 0.87, 0.95, P < 0.05). Children who were 7-9 years old were less likely to have a BCG scar than were children 6 years old. Children in the areas of the country more than two hours' driving distance from the capital city of Santo Domingo more often exhibited lower BCG scar prevalence levels than did children in Santo Domingo. A higher Rosa Index (better level of socioeconomic characteristics) was correlated with higher BCG scar prevalence values (r = 0.54, P < 0.05). CONCLUSIONS: Our study findings indicate that BCG coverage appears to be inadequate for schoolchildren in the Dominican Republic. Nevertheless, the presence of a scar in a higher proportion of younger children suggests that coverage has improved in recent years. More programmatic and economic emphasis needs to be placed on extending early BCG vaccination coverage to the areas of the country where vaccination coverage is lower, and on examining the potential role that poverty may have on vaccination effectiveness.

OBJETIVOS: Evaluar críticamente la prevalencia de cicatrices por la vacunación con el bacilo de Calmette-Guérin (BCG) en niños de 6 a 9 años de la República Dominicana y examinar la relación entre los factores nutricionales y socioeconómicos y la probabilidad de tener cicatriz de BCG. MÉTODOS: Para este estudio correlacional se empleó la base de datos del II Censo Nacional de Talla y Peso en Escolares de Primer Grado de Básica, realizado en la República Dominicana entre agosto de 2001 y mayo de 2002, para evaluar críticamente el nivel de cobertura nacional de la vacunación con BCG. Entre la información censal de los niños estaban si tenían cicatriz de BCG, su estado nutricional y sus datos demográficos básicos. Se desarrolló un nuevo indicador sociodemográfico, el "índice de Rosa", para analizar la posible influencia de la pobreza y de otras características ambientales en la presencia de esa cicatriz. Se emplearon modelos de regresión logística para predecir la presencia de la cicatriz de BCG. RESULTADOS: La prevalencia general de cicatrices de BCG fue de 55,3 por ciento (85 644/ 154 887). Los niños desnutridos presentaron una menor probabilidad de tener cicatriz de BCG que los niños con un adecuado estado nutricional (razón de posibilidades = 0,91; intervalo de confianza de 95 por ciento: 0,87 a 0,95; P < 0,05). Los niños de 7-9 años tuvieron menor probabilidad de tener cicatriz de BCG que los niños de 6 años. Los niños de zonas del país que se encuentran a más de dos horas de viaje de Santo Domingo, la capital, presentaron menor prevalencia de cicatrices de BCG con mayor frecuencia que los niños de Santo Domingo. Se encontró correlación entre tener un mayor índice de Rosa (mejor nivel en las características socioeconómicas) y una mayor prevalencia de cicatrices de BCG (r = 0,54; P < 0,05). CONCLUSIONES: Los resultados del presente estudio indican que la cobertura de vacunación de escolares con la vacuna BCG parece no ser la adecuada...

Suppression of human immunodeficiency virus type 1 viral load with selenium supplementation: a randomized controlled trial.

BACKGROUND: Despite findings that selenium supplementation may improve immune functioning, definitive evidence of its impact on human immunodeficiency virus (HIV) disease severity is lacking. METHODS: High selenium yeast supplementation (200 mug/d) was evaluated in a double-blind, randomized, placebo-controlled trial. Intention-to-treat analyses assessed the effect on HIV-1 viral load and CD4 count after 9 months of treatment. Unless otherwise indicated, values are presented as mean +/- SD. RESULTS: Of the 450 HIV-1-seropositive men and women who underwent screening, 262 initiated treatment and 174 completed the 9-month follow-up assessment. Mean adherence to study treatment was good (73.0% +/- 24.7%) with no related adverse events. The intention-to-treat analyses indicated that the mean change (Delta) in serum selenium concentration increased significantly in the selenium-treated group and not the placebo-treated group (Delta = 32.2 +/- 24.5 vs 0.5 +/- 8.8 microg/L; P<.001), and greater levels predicted decreased HIV-1 viral load (P<.02), which predicted increased CD4 count (P<.04). Findings remained significant after covarying age, sex, ethnicity, income, education, current and past cocaine and other drug use, HIV symptom classification, antiretroviral medication regimen and adherence, time since HIV diagnosis, and hepatitis C virus coinfection. Follow-up analyses evaluating treatment effectiveness indicated that the nonresponding selenium-treated subjects whose serum selenium change was less than or equal to 26.1 microg/L displayed poor treatment adherence (56.8% +/- 29.8%), HIV-1 viral load elevation (Delta = +0.29 +/- 1.1 log(10) units), and decreased CD4 count (Delta = -25.8 +/- 147.4 cells/microL). In contrast, selenium-treated subjects whose serum selenium increase was greater than 26.1 microg/L evidenced excellent treatment adherence (86.2% +/- 13.0%), no change in HIV-1 viral load (Delta = -0.04 +/- 0.7 log(10) units), and an increase in CD4 count (Delta = +27.9 +/- 150.2 cells/microL). CONCLUSIONS: Daily selenium supplementation can suppress the progression of HIV-1 viral burden and provide indirect improvement of CD4 count. The results support the use of selenium as a simple, inexpensive, and safe adjunct therapy in HIV spectrum disease. Trial Registration isrctn.org Identifier: ISRCTN22553118.

Impact of a massage therapy clinical trial on immune status in young Dominican children infected with HIV-1.

PURPOSE: The effectiveness of massage therapy on immune parameters was evaluated in young Dominican HIV+ children without current access to antiretroviral therapies. METHODS: Eligible children, who were followed at the Robert Reid Cabral Hospital (San Domingo, Dominican Republic), were randomized to receive either massage treatment or a control/friendly visit twice weekly for 12 weeks. Blood was drawn at baseline and following the 3-month intervention for determinations of CD4, CD8, and CD56 cell counts and percentage, along with activation markers (CD25 and CD69). RESULTS: Despite similar immune parameters at baseline in the two groups, significantly more of the control group exhibited a decline in CD4 cell count (>30%, p = 0.03), postintervention. The decrease was particularly evident in older (5-8 years) children in the control arm, who demonstrated a significant reduction in both CD4 and CD8 cell counts compared to massage-treated older children who remained stable or showed immune improvement. Additionally, a significant increase in CD4+CD25+ cells was observed over the 12-week trial in the massage-treated older children (p = 0.04) but not in the control group. In younger massage-treated children, (2-4 years old), a significant increase in natural killer cells was shown. CONCLUSION: Together these findings support the role for massage therapy in immune preservation in HIV+ children.

HIV knowledge and risk behaviors among women in law enforcement in Bogota, Colombia: potential role as community educators.

As HIV infection is increasing among women, evaluation, prevention, and education campaigns need to target this vulnerable population. Because of their frequent and accepted contact with members of the community, female law officers, if knowledgeable, could be well suited to provide information/education related to HIV/STD transmission. A survey of HIV/AIDS knowledge and risk behaviors was administered to 120 law enforcement women (LEW) and 60 women from the general population (GPW) in Bogotá, Colombia. LEW indicated a very high (90%) understanding of basic HIV knowledge. Although most (52%) of the LEW did not report high-risk behaviors, 29% indicated having unprotected sex during menses, and 17% had unprotected anal sex. This contrasts, however, with GPW, who were of similar age, but had a significantly higher prevalence (73%) of risky behaviors (P=.004). Moreover, 52% of the GPW reported having unprotected anal sex, and approximately half of this group (55%) indicated having unprotected sex during menses. Alcohol and drug users were also more prevalent in the GPW: 14% frequently used alcohol and 3% inhaled drugs during sexual encounters, contrasted to 2% of LEW reporting alcohol use. GPW were four times more likely than LEW, to engage in high-risk sexual practices [95% confidence interval (CI)=1.9-10.4, P=0.034]. Multivariate analyses indicated that alcohol and/or drug use were significantly associated with high-risk sexual practices [odds ratio (OR)=4.7, 95% confidence intervals (CI)=1.3-18.4, P=.02). Improved educational HIV/AIDS programs are needed, particularly for women in the general population, who use alcohol/drugs during sexual encounters, which account, at least in part, for their high-risk behaviors. Women in law enforcement, who appear knowledgeable and exhibit safer behaviors, could be useful educators for GPW. Because of their professional role in the community, training for LEW in HIV/AIDS education/prevention programs should be considered.

Increased risk of Pneumocystis carinii and community-acquired pneumonia with tobacco use in HIV disease.

OBJECTIVES: Tobacco smoking-related diseases continue to be of great health concern for the public, in general, and may be particularly deleterious for immunosuppressed HIV-positive individuals, who exhibit widespread tobacco use. METHODS: A total of 521 HIV-infected subjects consecutively admitted to Jackson Memorial Hospital between 2001-2002 were enrolled in the study. Research data included a medical history, details of tobacco and illicit drug use and complete computerized hospital information. Blood was drawn to obtain T lymphocyte profiles and viral load levels. Statistical analysis methods included Pearson, Student's t- and Chi-square tests and SAS Proc CATMOD. RESULTS: Tobacco use was prevalent, with 65% of the 521 HIV-positive hospitalized patients being current smokers. Overall, current tobacco users reported smoking an average of 15+/-13 cigarettes per day for an average of 15+/-14 years, with 40% smoking more than one pack per day. Pulmonary infections accounted for 49% of the total hospital admissions: 52% bacterial pneumonias, 24% Pneumocystis carinii pneumonia (PCP), 12% non-tuberculous mycobacterial diseases (NTM), 11% tuberculosis and 1% bronchitis. Many of the respiratory patients (46%) had been on highly active antiretroviral therapy (HAART) for over six months and 42% had received PCP and/or NTM prophylaxis. After matching the cases by HAART and CDC stage, the hazardous risk of being hospitalized with a respiratory infection was significantly higher for smokers than non-smokers (95% CI 1.33-2.83; p=0.003). Respiratory infections were noted in (37%) of the HAART-treated patients, and most (67%) occurred in smokers. CATMOD analyses controlling for HAART, viral load and CD4, indicated that HIV-infected smokers were three times more likely to be hospitalized with PCP and twice as likely to be hospitalized with community-acquired pneumonia than non-smokers, with increased risk related to the number of cigarettes/day in a dose-dependent manner. CONCLUSIONS: Tobacco use, which is widespread among HIV-infected subjects, increases the risk of pulmonary diseases, particularly PCP and CAP, two respiratory infections with high prevalence and morbidity risks even in the era of HAART.

Massage treatment in HIV-1 infected Dominican children: a preliminary report on the efficacy of massage therapy to preserve the immune system in children without antiretroviral medication.

OBJECTIVES: More than 1.4 million children are living with HIV and global access to antiretrovirals is not yet readily available. Massage therapy, which has been shown to improve immune function in HIV+ adults and adolescents, may provide an important complementary treatment to boost immune status in young children living with HIV disease, especially those without access to antiretroviral medications. No studies have been conducted, however, that specifically target massage therapy to enhance immune function in HIV+ children. DESIGN: Clinical trial with eligible, consented HIV+ children randomized to receive either massage therapy or a friendly visit (controls). SETTINGS/LOCATION: CENISMI/Robert Reid Cabral Hospital, Santo Domingo, Dominican Republic. SUBJECTS: HIV+ children ages 2-8 years. INTERVENTION: Massage therapy sessions (20 minutes, twice weekly, for 12 weeks), conducted by trained nurses, following a structured protocol of moderate pressure stroking and kneading of muscles, using a non-scented oil. The friendly visit control group, (reading, talking, playing quiet games), met with the nurse twice weekly for 12 weeks. OUTCOME MEASURES: At the initial evaluation, and following the 12-week intervention, blood was drawn to determine absolute helper (CD4/T4) and suppressor (CD8/T8) counts. RESULTS: Children in the control arm had a greater relative risk of CD4 count decline (>20%) than massage-treated children (RR = 5.7, p = 0.03). Lymphocyte loss was also more extensive in the controls (p < 0.02), and more of the control group than the massage group lost >50 CD8 lymphocytes (p = 0.03). CONCLUSIONS: The efficacy of massage therapy in maintaining immunocompetence may offer a viable alternative to the thousands of children worldwide without antiretroviral access.

"I will miss the study, God bless you all": participation in a nutritional chemoprevention trial.

Randomized controlled clinical trials are often considered to be the "gold standard" for health research. Consequently, understanding the reasons people participate in these trials, especially minority groups who are often under-represented in clinical trials, or populations who have chronic illnesses or abuse drugs, is salient for successful recruitment, retention, and project design. This paper describes the results of a study that was designed to examine some of the ways in which participants in a randomized double blind clinical trial perceived their participation in the clinical trial, and the reasons they gave for continuing in the study. All of the participants were individuals who were using drugs and were infected with the HIV-1 virus, and had participated in a chemoprevention trial. The data from an exit interview were analyzed thematically in order to reveal units of meaning concerning participation and continuation in the clinical trial. The analysis revealed 3 higher-level concepts, or themes, that guided participation: increased health awareness, personal enhancement, and sociability. The data clearly indicated that involvement and retention in the trial were directly related to the ways in which the participants interpreted the study, perceived the benefits they derived from participating, and imbued their participation with value so that it was important and relevant to their own perceptions of health, as well as personal and social well being.

Preventing mother-to-child HIV transmission in a developing country: the Dominican Republic experience.

Transmission of HIV in the Dominican Republic occurs primarily through heterosexual contact. As part of a continuing strategy to prevent and contain the spread of HIV infection, the Ministry of Health of the Dominican Republic established an integrated package of interventions to reduce HIV mother-to-child transmission that was initiated on May 15, 2000. The program was designed to be implemented in 3 phases. The 1st phase included 4 mother and child hospitals; the 2nd phase included 8 mother and child health institutions in Santo Domingo, the capital of the Dominican Republic, and 7 additional mother and child hospitals. The 3rd phase will include the remaining 12 mother and child health care institutions of the Dominican Republic. Evaluation of the 1st year of this program, involving 8 hospitals and >40000 pregnant women, identified specific benefits and limitations. Low numbers of voluntary counseling sessions (6528/42666 = 28%) and inadequate number of HIV rapid tests (23067/42666 = 54%) were the 2 main obstacles encountered. From the 23067 pregnant women tested, 581 (2.5%) were HIV positive. Advantageous aspects included the successful administration of antiretroviral treatment to 89% (164/185) of the mothers and 98% (183/186) of the children. Cesarean section was performed in 67% (124/185) of the HIV-positive pregnant women, and infant formula was dispensed to 47% (87/186) of all cases. These findings demonstrate the feasibility of implementing a large-scale program to prevent mother-to-child transmission in a developing country.

Psychological burden in the era of HAART: impact of selenium therapy.

OBJECTIVE: To determine the impact of nutritional (selenium) chemoprevention on levels of psychological burden (anxiety, depression, and mood state) in HIV/AIDS. METHOD: A randomized, double-blind, placebo-controlled selenium therapy (200 microg/day) trial was conducted in HIV+ drug users from 1998-2000. Psychosocial measures (STAI-State and Trait anxiety, BDI-depression, and POMS- mood state), clinical status (CD4 cell count, viral load), and plasma selenium levels were determined at baseline and compared with measurements obtained at the 12-month evaluation in 63 participants (32 men, 31 women). RESULTS: The majority of the study participants reported elevated levels of both State (68%) and Trait (70%) anxiety. Approximately 25% reported overall mood distress (POMS > 60) and moderate depression (BDI > 20). Psychological burden was not influenced by current drug use, antiretroviral treatment, or viral load. At the 12-month evaluation, participants who received selenium reported increased vigor (p = 0.004) and had less anxiety (State, p = 0.05 and Trait, p = 0.02), compared to the placebo-treated individuals. No apparent selenium-related affect on depression or distress was observed. The risk for state anxiety was almost four times higher, and nearly nine times greater for trait anxiety in the placebo-treated group, controlling for antiretroviral therapy, CD4 cell decline (> 50 cells) and years of education. CONCLUSIONS: Selenium therapy may be a beneficial treatment to decrease anxiety in HIV+ drug users who exhibit a high prevalence of psychological burden.

HIV treatment in drug abusers: impact of alcohol use.

Studies of alcohol use in HIV-1 infected patients have resulted in conflicting and limited information regarding prevalence, as well as impact on HIV replication, disease progression and response to antiretroviral therapy. Alcohol, drug abuse and past medical information, including antiretroviral treatment, were obtained using research questionnaires and medical chart review in 220 HIV-1 infected drug users. A physical examination was conducted and blood was drawn to evaluate immune measures and nutritional status. Heavy alcohol consumption, defined as daily or 3 - 4 times per/week, was reported in 63% of the cohort. Men (odds ratio (OR) = 2.6, 95% CI 1.13 - 5.99, p = 0.013), and participants between 35 and 45 years of age were three times more likely to be heavy alcohol users (p = 0.006 and 0.0009, respectively). Low serum albumin levels were more evident in heavy alcohol users than non-drinkers (p = 0.003). Heavy alcohol users receiving antiretroviral therapy were twice as likely to have CD4 counts below 500 than light or non-drinkers (95% CI, 1 - 5.5, p = 0.03), and highly active antiretroviral therapy (HAART)-treated heavy alcohol users were four times less likely to achieve a positive virological response (95% CI, 1.2 - 17, p = 0.04). Alcohol consumption is prevalent in our HIV-1 infected drug user cohort and significantly impacts both immunological and virological response to HAART treatment.
