Changes in liver function test levels in HIV patients undergoing highly active antiretroviral therapy (HAART). Longitudinal study in Lima, Peru / Cambios en los valores de las pruebas de función hepática en pacientes con VIH en terapia antirretroviral de gran actividad (TARGA). Estudio longitudinal en Lima, Perú

Abstract Introduction: Estimating and monitoring changes in liver function tests is necessary to prevent the occurrence of chronic liver disease in HIV patients undergoing highly active antiretroviral therapy (HAART). Objective: To determine the variation liver profile test levels in HIV patients undergoing HAART. Materials and methods: Retrospective longitudinal study conducted in 100 HIV patients treated at the Hospital Nacional Hipólito Unanue, Lima, Peru, between 2015 and 2017. Patients in all stages of clinical infection under HAART and with liver function panel results for alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), and total protein (TP) were included. Three follow-up liver function tests (every 3 months) were performed while undergoing HAART and participants were categorized as having normal or elevated levels for all liver markers. Differences between the samples analyzed were determined using the paired-samples T test, with a 95% confidence interval and a significance level of p<0.05. Results: Participants' mean age was 33±9.56 years and 67% were male. Mean serum AST, ALT and ALP values decreased between the first and the third measurement (p=0.021, p=0.076 and p=0.002, respectively). No significant differences in GGT and TP levels were observed between the three measurements, nor between patients with normal and elevated AST, ALT, ALP and TP values, but significant differences were observed for GGT (p=0.010). Conclusions: Variations in liver marker levels were observed in all participants, with a decreasing trend in AST, ALT and ALP between the early and late stages of HAART, implying that this therapy could play a role in liver tissue damage.

Resumen Introducción. Para prevenir el desarrollo de enfermedad hepática crónica en pacientes con VIH, durante la terapia antirretroviral de gran actividad (TARGA) se deben estimar y monitorear cambios en el perfil hepático. Objetivo. Determinar la variación de las concentraciones del perfil hepático en pacientes con VIH durante la TARGA. Materiales y métodos. Estudio retrospectivo longitudinal realizado en 100 pacientes con VIH atendidos en el Hospital Nacional Hipólito Unanue, Lima, Perú, entre 2015 y 2017. Se incluyeron pacientes en todos los estadios de infección clínica que estuvieran recibiendo TARGA y en los que se contara con resultados del perfil hepático para alanina aminotransferasa (ALT), aspartato aminotransferasa (AST), fosfatasa alcalina (FA), gammaglutamiltranspeptidasa (GGT) y proteínas totales (PT). Se realizaron tres análisis de control de la función hepática durante la TARGA (1 cada 3 meses) y los participantes se agruparon en niveles normales y elevados para todos los marcadores hepáticos. Las diferencias entre las muestras analizadas fueron determinadas mediante la prueba t-Student para muestras relacionadas, con un intervalo de confianza de 95% y un nivel de significancia de p<0.05. Resultados. La edad promedio fue de 33±9.56 años y el 67% fueron varones. Los valores séricos promedio de AST, ALT y FA disminuyeron entre la primera y la tercera medición (p=0.021, p=0.076 y p=0.002, respectivamente). No se observaron diferencias significativas en los niveles de GGT y PT entre las tres mediciones, ni entre los pacientes con valores normales y elevados para AST, ALT, FA y PT, pero sí para GGT (p=0.010). Conclusiones. Se observaron variaciones en los niveles de los marcadores hepáticos de todos los participantes, con una tendencia a la reducción en AST, ALT y FA entre las etapas iniciales y finales de la terapia, lo que implica que la TARGA podría ejercer un rol en el daño tisular hepático.

Online Training in Accessibility and Design for All: A Tool to Train Post-COVID Inclusive Graduates.

Agenda 2030 expresses, through the Sustainable Development Goals (SDG), and in particular through No. 4, the need to ensure an inclusive and equitable education, which promotes learning opportunities for all. At the university level, all students are urged to acquire the necessary theoretical and practical knowledge to promote sustainable development, so that they become graduates capable of facing the challenges of the future and the real demands of a society marked by heterogeneity, including the needs of people with some kind of disability. In this sense, the present work analyzed the impact of a transversal training program in Design for All on university degree students. For this purpose, a descriptive and comparative ex post facto study was developed in which the impact of an online training program was quantified by establishing comparative pre- and post-training. The results indicate that the approach, through the delivery of a training xplain eon Design for All, contributed to a change in the perceptions of students regarding disability, its role in the university and in the future workplace. Furthermore, it increased the knowledge of institutional action undertaken in terms of awareness and approach to human disability.

Lack of Association of IL6 polymorphism with the susceptibility to Chagas disease in Latin American populations.

The aim of the present study was to analyze IL6 rs1800795 genetic variant in the susceptibility to Trypanosoma cruzi infection and in the development of chronic Chagas cardiomyopathy (CCC), in five independent Latin American cohorts. A total of 3,087 individuals from Latin American countries (Argentina, Bolivia, Peru, and two cohorts from Colombia) were studied. In all cohorts, patients were classified as seropositive for T. cruzi antigens (n= 1,963) and seronegative (n= 1,124). Based on clinical evaluation, the seropositive patients, were classified as CCC (n= 900) and asymptomatic (n= 1,063). No statistically significant differences in the frequency of IL6 rs1800795 between seropositive and seronegative, or between CCC and asymptomatic patients, were found. Furthermore, after the meta-analysis no statistically significant differences were observed. Our results do not support a contribution of IL6 rs1800795 genetic variant in the susceptibility to the infection and the development of chronic Chagas cardiomyopathy in the studied populations.

Genetic polymorphisms of IL17A associated with Chagas disease: results from a meta-analysis in Latin American populations.

Genetic factors and the immunologic response have been suggested to determine the susceptibility against the infection and the outcome of Chagas disease. In the present study, we analysed three IL17A genetic variants (rs4711998, rs8193036 and rs2275913) regarding the predisposition to Trypanosoma cruzi infection and the development of chronic Chagas cardiomyopathy (CCC) in different Latin American populations. A total of 2,967 individuals from Colombia, Argentina, Bolivia and Brazil, were included in this study. The individuals were classified as seronegative and seropositive for T. cruzi antigens, and this last group were divided into asymptomatic and CCC. For T. cruzi infection susceptibility, the IL17A rs2275913*A showed a significant association in a fixed-effect meta-analysis after a Bonferroni correction (P = 0.016, OR = 1.21, 95%CI = 1.06-1.41). No evidence of association was detected when comparing CCC vs. asymptomatic patients. However, when CCC were compared with seronegative individuals, it showed a nominal association in the meta-analysis (P = 0.040, OR = 1.20, 95%CI = 1.01-1.45). For the IL17A rs4711998 and rs8193036, no association was observed. In conclusion, our results suggest that IL17A rs2275913 plays an important role in the susceptibility to T. cruzi infection and could also be implicated in the development of chronic cardiomyopathy in the studied Latin American population.

HIV Testing and Mistaken Beliefs about Immigration Laws.

Evidence suggests that migrants may underutilize USA health care because of misconceptions about immigration-related consequences of health care use. This study aimed to explore whether common misconceptions about the immigration consequences of seeking health care, receiving an HIV test, and being diagnosed with HIV were associated with participant self-report of never having received an HIV test. The study sample comprised 297 adult, sexually active, documented and undocumented Spanish-speaking Latino migrants. Participants completed a cross-sectional survey via ACASI. In multiple logistic regression analyses controlling for sociodemographic variables and HIV stigma, misconceptions about laws emerged as a strong predictor of never having received an HIV test (p < .001). Associations between participants' endorsement of misconceptions and their HIV testing history suggest that incorrect perceptions of laws do deter some subgroups of USA Latino migrants from HIV testing. Identifying misconceptions about negative immigration consequences of engaging in important health behaviors should be a community health research priority.

Rituximab-Treated Pemphigus Foliaceus in a Schizophrenic Patient: A Challenging Exercise in Diagnosis, Management, and Follow-Up.

Dermatology was consulted in the care of a 58-year-old man with a history of paranoid schizophrenia, neuroleptic malignant syndrome, a positive purified protein derivative test, and a lack of bathing for approximately 4 years who had been admitted to the hospital because of thick, crusted lesions over an increasing portion of his body. Admitted involuntarily, he was disinterested in the history, physical examination, and diagnostic testing. Comorbid schizophrenia presented a unique challenge because he was unable to participate in his care effectively. His story was told through caregivers. Although mostly compliant, the patient was reserved and indifferent, and had little to add even with direct questions.

The Development and Psychometric Properties of the Immigration Law Concerns Scale (ILCS) for HIV Testing.

To develop, pilot test, and conduct psychometric analyses of an innovative scale measuring the influence of perceived immigration laws on Latino migrants' HIV-testing behavior. The Immigration Law Concerns Scale (ILCS) was developed in three phases: Phase 1 involved a review of law and literature, generation of scale items, consultation with project advisors, and subsequent revision of the scale. Phase 2 involved systematic translation- back translation and consensus-based editorial processes conducted by members of a bilingual and multi-national study team. In Phase 3, 339 sexually active, HIV-negative Spanish-speaking, non-citizen Latino migrant adults (both documented and undocumented) completed the scale via audio computer-assisted self-interview. The psychometric properties of the scale were tested with exploratory factor analysis and estimates of reliability coefficients were generated. Bivariate correlations were conducted to test the discriminant and predictive validity of identified factors. Exploratory factor analysis revealed a three-factor, 17-item scale. subscale reliability ranged from 0.72 to 0.79. There were significant associations between the ILCS and the HIV-testing behaviors of participants. Results of the pilot test and psychometric analysis of the ILCS are promising. The scale is reliable and significantly associated with the HIV-testing behaviors of participants. Subscales related to unwanted government attention and concerns about meeting moral character requirements should be refined.

Psoriasiform Sarcoidosis: Collision of Two Entities or Expression of One Common Pathogenesis?

BACKGROUND: Psoriasiform lesions are an established, but rare, manifestation of sarcoidosis. Only 0.9 percent of patients with cutaneous sarcoidosis develop this form of the disease. OBSERVATION: The authors present a case of a 61-year-old woman with a history of pulmonary sarcoidosis who presented to their dermatology clinic with thick plaques resembling psoriasis. Biopsy of one of the lesions revealed sarcoidal granulomas in association with psoriasiform changes. CONCLUSION: Psoriasiform lesions are a rare manifestation of sarcoidosis. The authors theorize that the co-expression of TNF-α in both entities is a possible explanation of the psoriasiform expression of sarcoidosis.

Eosinophil-dependent skin innervation and itching following contact toxicant exposure in mice.

BACKGROUND: Contact toxicant reactions are accompanied by localized skin inflammation and concomitant increases in site-specific itch responses. The role(s) of eosinophils in these reactions is poorly understood. However, previous studies have suggested that localized eosinophil-nerve interactions at sites of inflammation significantly alter tissue innervation. OBJECTIVE: To define a potential mechanistic link between eosinophils and neurosensory responses in the skin leading to itching. METHODS: BALB/cJ mice were exposed to different contact toxicants, identifying trimellitic anhydride (TMA) for further study on the basis of inducing a robust eosinophilia accompanied by degranulation. Subsequent studies using TMA were performed with wild type versus eosinophil-deficient PHIL mice, assessing edematous responses and remodeling events such as sensory nerve innervation of the skin and induced pathophysiological responses (ie, itching). RESULTS: Exposure to TMA, but not dinitrofluorobenzene, resulted in a robust eosinophil skin infiltrate accompanied by significant levels of degranulation. Follow-up studies using TMA with wild type versus eosinophil-deficient PHIL mice showed that the induced edematous responses and histopathology were, in part, causatively linked with the presence of eosinophils. Significantly, these data also demonstrated that eosinophil-mediated events correlated with a significant increase in substance P content of the cutaneous nerves and an accompanying increase in itching, both of which were abolished in the absence of eosinophils. CONCLUSIONS: Eosinophil-mediated events following TMA contact toxicant reactions increase skin sensory nerve substance P and, in turn, increase itching responses. Thus, eosinophil-nerve interactions provide a potential mechanistic link between eosinophil-mediated events and neurosensory responses following exposure to some contact toxicants.

Lessons learned while preparing a tailored, self-help, technology-driven intervention for national dissemination.

Tailored health interventions have been found to be effective in various areas of health promotion because of their delivery of customized content, which focuses the prevention messages more closely on the individual's risk behavior. However, the use of tailored interventions in the prevention of STD/HIV has been limited, and there is a void in the literature on translating tailored interventions into practice. This paper discusses the process of translating a tailored, self-help, technology-driven STD/HIV prevention intervention from research-to-practice. Three agencies were selected during the translation process to test the intervention materials and provided valuable lessons learned for translating a tailored intervention into practice. A racially diverse group of more than 250 women in six states participated in the intervention during this pilot test. Lessons learned for research-to-practice efforts for tailored interventions are presented, including expanding the reach of such interventions by making them more compatible for mobile technology.

SOMOS: evaluation of an HIV prevention intervention for Latino gay men.

Latino gay men face multiple barriers to human immunodeficiency virus (HIV) prevention, in particular a lack of intervention programs that integrate prevention messages with cultural norms and address issues of social marginalization from multiple communities (gay community and Latino community), homophobia and racism. In order to address these specific issues, a multilayered HIV intervention was designed to incorporate and integrate psychosocial and community factors through multiple session groups, social marketing and community presentations. Participants learned strategies for effective community leadership and were encouraged to provide HIV education and address internalized homophobia in their communities. There were a total of 113 Latino gay male participants. Pretests and post-tests at 90-day follow-up were administered to measure knowledge, attitudes and behaviors related to HIV infection, self-efficacy, internalized homophobia and connectedness (i.e. gay community affiliation and social provisions); a risk index was calculated to measure level of behavioral risk for HIV infection. Participants demonstrated lower risk indices and a decrease in partners at 3 and 6 months after the intervention. There was also an increase in reported social support resources, along with an increase in group identification. Connectedness was a strong predictor of the number of sexual partners at the 90-day follow-up. This homegrown program represents a culturally responsive, highly needed and relevant intervention that should be subjected to further rigorous testing.

The CHANGE approach to capacity-building assistance.

The CHANGE approach to capacity-building assistance (CBA), developed over 4 years by the Latino Commission on AIDS Manos Unidas' Program to assist Latino-serving community-based HIV prevention programs in eight northern U.S. states, Puerto Rico, and the U.S. Virgin Islands, is a system for providing community-based organizations (CBOs) with not only the skills to implement interventions from the Centers for Disease Control and Prevention's Diffusion of Effective Behavioral Interventions (DEBI) project, but also the capacity to reorient to the disruptive innovation of the DEBIs. The CHANGE (customized, holistic, analytical, network-building, grassroots, evaluatory) approach entails an integrated CBA-model emphasizing community and programmatic diagnosis and reflection and the enhancement of staff skills through tailored curricula in six areas: community-assessment, target-refinement, recruitment and retention, basic skills, program implementation, and evaluation. The CHANGE model encourages active CBO participation in the learning process rooted in the experiences of the organization as a member of its community.

Acquisition of new sexual partners among women with HIV infection: patterns of disclosure and sexual behavior within new partnerships.

UNLABELLED: This study describes the sexual behavior of HIV-positive women within new versus more established relationships and determines whether beliefs about HIV antiretroviral therapy (ART) impact these behaviors. The Women's Interagency HIV Study is a longitudinal cohort study of HIV among women in the United States. Sexually active HIV-positive women (N = 1,090) completed interviews on beliefs and behaviors at 6-month intervals. Data were analyzed for the period between April 2002 and March 2003. Of 1,517 sexual partners reported, 32% were newly acquired within the previous 6 months. As compared with more established sexual relationships, newer partnerships were characterized by greater condom use consistency (odds ratio = 1.8, 95% confidence interval = 1.4 -2.3). Holding beliefs that ART is protective for HIV transmission impacted the relationship between partner type and condom use. In established relationships, 63% reported consistent condom use if they believed that ART is not protective, whereas 54% reported consistent condom use if they believed that ART is protective. CONCLUSIONS: These findings highlight the importance of ongoing support for sexual risk reduction among women with HIV-infection and for strategies that reduce the strength of relationships between ART beliefs and sexual risk behavior.

Diagnosis and treatment of malignant melanoma of the foot.

BACKGROUND: Patients diagnosed with melanoma of the foot have been reported to have a poor prognosis. We reviewed our experience at a tertiary-care medical clinic to determine the disease course in patients diagnosed with melanoma of the foot. METHODS: A retrospective review was performed of 38 patients with a diagnosis of primary or locally recurrent melanoma of the foot treated between January, 1988, and July, 2004. The main outcome measures included methods of diagnosis, clinical and histopathologic features, and patterns of recurrence. RESULTS: The mean age at diagnosis was 61 years; most were women (58%) and Caucasian (95%). The average time to diagnosis was 17 months. Initial clinical diagnosis had been considered benign in 12 (32%). The median Breslow thickness was 1.75 mm, T1 lesions were the most common, and acral lentiginous melanoma accounted for 42%. Thirteen patients (34%) had ulcerated lesions. Sentinel lymph node biopsy specimens of 25 patients identified four (16%) with metastatic disease. Surgical complications occurred in 12 patients, usually after skin graft or soft-tissue flap reconstruction. Systemic recurrence developed in six patients, four of whom also had regional recurrence. CONCLUSIONS: Most patients were elderly Caucasian women and most presented with early-stage disease, but diagnosis can be difficult and a subgroup presented with thick melanomas. Reconstructive surgical procedures had a high rate of complications; however, overall functional outcomes were good. Stage of cancer at diagnosis was associated with systemic metastases.

Social marketing techniques for public health communication: a review of syphilis awareness campaigns in 8 US cities.

OBJECTIVES: To describe the social marketing approaches used to increase syphilis awareness in 8 US cities. METHODS: We reviewed the typical academic approach for developing social marketing campaigns and interviewed health department staff responsible for social marketing campaigns in each city. RESULTS: Using social marketing techniques such as target segmentation, concept testing of materials, and formative evaluation, campaign planners throughout the 8 cities developed a variety of approaches to reach their target audiences. Preliminary results suggest 71% to 80% of men who have sex with men interviewed were aware of the campaigns, and 45% to 53% of them reported they were tested due to the campaigns. CONCLUSIONS: Campaigns should address the local epidemic and target audience with culturally appropriate messages.
