The present work entitled "Self-esteem and unconditional acceptance of oneself, in seropositive people", highlights the problem of real states, which seropositive people face, to situations and intercessions related to self-esteem. This followed the behavior of HIV positive people, attitudes towards other people or vis-à-vis their own lives. Self-esteem is an element of the self and refers to affective living, to the emotions that the individual experiences when referring to himself. It is a make-up of the cognitive scheme relating to oneself. The idea that self-esteem is one of the factors that are associated with mental health is an integral part of psychology. The level of self can influence the habits and manifestations of the individual, so in the case of a low level the person gives up a succession of attractive goals, such as establishing close interpersonal relationships, choosing desired professions or living a pleasant life full of accomplishments and satisfactions. A low self-esteem can turn a healthy and intelligent person into a powerless person. The transition from a healthy and high self-esteem to a low self-esteem can be achieved by triggering strong mechanisms, in critical situations such as in the case of the presented theme, the establishment of a positive serodiagnostic. This fact causes the person to adopt ub devaluation behavior. The work being focused on self-esteem is designed so as to highlight the main aspects of the subject, so it is structured on chapters as follows in those presented below.

La percepción social del Sida se construye por el contexto cultural. Los factores sociales influyen la percepción del riesgo a la infección por VIH y en las actitudes hacia las personas que viven con la enfermedad. Con el objetivo de examinar si existen diferencias culturales en la percepción social del sida, se evaluaron a 200 jóvenes españoles (Medad = 20,25; DT = 1,88) y 183 jóvenes argentinos (Medad = 22,30; DT = 2,89). Se utilizó el Cuestionario de Prevención del Sida que evalúa los principales componentes de los modelos de prevención sobre el VIH. Los resultados muestran diferencias estadísticamente significativas en la probabilidad percibida de infección por VIH, siendo los argentinos los que identifican mayor riesgo que los españoles (p≤.001). No existen diferencias estadísticamente significativas en el temor percibido (p = .408). Los jóvenes de ambos países atribuyen mayor riesgo de infección al colectivo de drogodependientes, seguido de los heterosexuales y homosexuales. No obstante, los españoles atribuyen mayor probabilidad de infección a los drogodependientes (p≤.001) comparados con los argentinos. Al contrario, los argentinos atribuyen más riesgo a los heterosexuales (p≤.001) y homosexuales (p≤.001) con respecto a los españoles. Por otra parte, los jóvenes argentinos valoran de forma más elevada el sufrimiento a nivel físico y social que experimenta una persona que vive con VIH (p≤.001). No se encuentran diferencias significativas a nivel estadístico en la solidaridad hacia los enfermos (p = .403). Por último, los jóvenes de ambos países se comportarían igual o apoyarían más si se enterasen que un amigo es portador del VIH (p = .053). La percepción social puede actuar como factor protector o dificultador de la prevención primaria y secundaria y ser un importante factor en la disminución o potenciación del estigma hacia los enfermos.

to understand the representational content about HIV/AIDS among seropositive elderly people. a qualitative study carried out from April to May 2017, in the city of Recife/PE, with 48 seropositive elderly people, through a semi-structured interview. The Social Representations Theory was used as theoretical framework and the method of lexical analysis through IRAMUTEQ software. it was observed that the social representation of HIV is structured around the proximity of death and that it is a disease of restricted groups, leading to feelings of sadness. On the other hand, it is evident a transformation of the representation linked to the reified knowledge, leading to the process of naturalization of the disease. it is concluded that the elderly living with HIV, when they undergo a process of reframing about the disease, become more flexible to deal with their condition of seropositivity.

AimThis study determined the factors associated with pregnancy uptake decision among seropositive HIV people receiving antiretroviral therapy in sub‐Saharan Africa.DesignSystematic review.MethodsThe population, intervention, comparison and outcomes framework was adopted to search for literature after a scoping review using the preferred reporting items for systematic reviews and meta‐analyses guidelines adopted in searching, and screening articles from four databases (PubMed, Cumulative Index to Nursing and Allied Health Literature, Embase, and Google scholar) to find 12 articles suitable for this study.ResultsMotivators of pregnancy uptake among HIV‐positive women include desire to have children, knowledge about PMTCT, cultural duty for married women to have children, and household income. Demotivating factors included the modern method of contraception and burden associated with pregnancy.ConclusionThere is a need to improve on services that reduce conception‐related risks especially for women who choose to conceive and to incorporate fertility‐related counselling into HIV treatment services.

Reactivation in the oral cavity either symptomatically (recrudescence) or without symptoms (recurrence) may contribute to the transmission of herpes simplex virus type 1 (HSV-1), especially in critical areas of exposure such as dentistry. In order to measure the frequency of HSV-1 reactivation, nested polymerase chain reaction (PCR) was performed on oral swabs collected from 30 healthy people over a period of 58-161 days. In total 19 of 25 (76%) seropositive people were PCR-positive at least once, 6 of these 19 (32%) had recrudescence and 13 (68%) had only asymptomatic reactivation. Frequencies of additional recurrences were higher in people showing symptomatic reactivation than in those who had only recurrences. Recrudescence is a risk factor for elevated levels of asymptomatic HSV-shedding. In most cases HSV-1 was detected only by nested PCR investigated by early onset of therapy or time span before sampling.

Minimal data exist on pregnancy following recovery from Ebola in people of child-bearing potential (females aged roughly 18-45 years). The aim of this study was to assess viral persistence or reactivation in pregnancy, the frequency of placental transfer of anti-Ebola IgG antibodies, and pregnancy outcomes in this population. In this observational cohort study, we studied self-reported pregnancies in two groups: seropositive people who had recovered from Ebola virus disease (seropositive group) and seronegative people who had close contact with people with Ebola (seronegative group). Participants had enrolled in the PREVAIL III longitudinal study and were exposed during the 2014-2016 Liberian Ebola outbreak. The primary outcome was pregnancy result. We assessed rates of livebirths and other pregnancy results in both study groups, and presence of Ebola RNA by PCR in samples of placenta, maternal and cord blood, breastmilk, and vaginal secretions from people who had recovered from Ebola who conceived a median of 14 months after acute Ebola virus disease. Mixed-model logistic regression evaluated associations between first-reported pregnancy outcome, age, and study group. Growth and neurodevelopment in the infants born to people in the seropositive group were assessed at 6-month intervals for 2 years. Data were accrued by PREVAIL III study staff. 1566 participants were enrolled between June 17, 2015, and Dec 14, 2017, of whom 639 became pregnant (215 seropositive, 424 seronegative) and 589 reported pregnancy outcomes (206 seropositive, 383 seronegative). 105 infants born to 98 mothers in the seropositive group were enrolled in the birth cohort. Ebola RNA was not detected in 205 samples of placenta, cord blood, or maternal blood taken at birth from 54 mothers in the seropositive group, nor in 367 vaginal swabs. Viral RNA was found in two of 354 longitudinal breastmilk samples. All but one of 57 infants born during these 54 births were seropositive for anti-Ebola antibodies. Neonates showed high concentrations of anti-Ebola IgG, which declined after 6 months. Odds of adverse pregnancy outcome among the two groups were indistinguishable (OR 1·13, 95% CI 0·71-1·79). Compared with WHO standards, infants born to those in the seropositive group had lower median weight and length, and larger median head circumference over 2 years. Compared with a cohort from the USA accrual of gross motor developmental milestones was similar, whereas attainment of pincer grasp and early vocalisation were mildly delayed. The risks of Ebola virus reactivation in the peripartum and postpartum period and of adverse birth outcomes are low in those who have recovered from Ebola virus disease and become pregnant approximately 1 year after acute Ebola virus disease. The implication for clinical practice is that care of people who are pregnant and who have recovered from Ebola can be offered without risks to health-care providers or stigmatisation of the mothers and their offspring. The implication for prospective mothers is that safe pregnancies are entirely possible after recovery from Ebola.

Immunogenic Nature of a Pol Gene Product of HTLV-III/LAV

The probability that an uninfected Triatoma infestans would become infected with Trypanosoma cruzi after a single feed on people or dogs seropositive for T. cruzi was estimated in Amama, a rural village in northwest Argentina where transmission had resurged four years earlier. The prevalence of seropositivity for T. cruzi was 34.2% among 225 people tested, and 65.1% among 83 dogs tested. Parasitemia was detected by xenodiagnosis in 29.3% of 41 seropositive persons and in 85.3% of 34 seropositive dogs. Parasitemia decreased with age more sharply in seropositive people than in seropositive dogs. Seropositive humans infected 2.6% (95% confidence interval = 1.6%-3.6%) of 963 third or fourth instar nymphs fed once on them, whereas dogs infected 48.7% (44.7%-52.7%) of 610 nymphs. The probability of bug infection increased significantly with instar and was positively related to molting success. The infectivity to bugs of seropositive dogs was 12 times higher than that of seropositive children, and 100 times higher than that of seropositive adults. The weighted probability of infection of an uninfected bug fed randomly on any dog (0.3082) was about 50 times higher than that of bugs fed on any human (0.0062). Such differences in relative infectivity, combined with the relative host-feeding preference of domiciliary Triatoma infestans for dogs, reinforces the important role of domestic dogs as a risk factor for the domestic transmission of T. cruzi.

SummaryBackgroundPeople living with HIV are at an increased risk of fatal outcome when admitted to hospital for severe COVID-19 compared with HIV-negative individuals. We aimed to assess safety and immunogenicity of the ChAdOx1 nCoV-19 (AZD1222) vaccine in people with HIV and HIV-negative individuals in South Africa.MethodsIn this ongoing, double-blind, placebo-controlled, phase 1B/2A trial (COV005), people with HIV and HIV-negative participants aged 18–65 years were enrolled at seven South African locations and were randomly allocated (1:1) with full allocation concealment to receive a prime-boost regimen of ChAdOx1 nCoV-19, with two doses given 28 days apart. Eligibility criteria for people with HIV included being on antiretroviral therapy for at least 3 months, with a plasma HIV viral load of less than 1000 copies per mL. In this interim analysis, safety and reactogenicity was assessed in all individuals who received at least one dose of ChAdOx1 nCov 19 between enrolment and Jan 15, 2021. Primary immunogenicity analyses included participants who received two doses of trial intervention and were SARS-CoV-2 seronegative at baseline. This trial is registered with ClinicalTrials.gov, NCT04444674, and the Pan African Clinicals Trials Registry, PACTR202006922165132.FindingsBetween June 24 and Nov 12, 2020, 104 people with HIV and 70 HIV-negative individuals were enrolled. 102 people with HIV (52 vaccine; 50 placebo) and 56 HIV-negative participants (28 vaccine; 28 placebo) received the priming dose, 100 people with HIV (51 vaccine; 49 placebo) and 46 HIV-negative participants (24 vaccine; 22 placebo) received two doses (priming and booster). In participants seronegative for SARS-CoV-2 at baseline, there were 164 adverse events in those with HIV (86 vaccine; 78 placebo) and 237 in HIV-negative participants (95 vaccine; 142 placebo). Of seven serious adverse events, one severe fever in a HIV-negative participant was definitely related to trial intervention and one severely elevated alanine aminotranferase in a participant with HIV was unlikely related; five others were deemed unrelated. One person with HIV died (unlikely related). People with HIV and HIV-negative participants showed vaccine-induced serum IgG responses against wild-type Wuhan-1 Asp614Gly (also known as D614G). For participants seronegative for SARS-CoV-2 antigens at baseline, full-length spike geometric mean concentration (GMC) at day 28 was 163·7 binding antibody units (BAU)/mL (95% CI 89·9–298·1) for people with HIV (n=36) and 112·3 BAU/mL (61·7–204·4) for HIV-negative participants (n=23), with a rising day 42 GMC booster response in both groups. Baseline SARS-CoV-2 seropositive people with HIV demonstrated higher antibody responses after each vaccine dose than did people with HIV who were seronegative at baseline. High-level binding antibody cross-reactivity for the full-length spike and receptor-binding domain of the beta variant (B.1.351) was seen regardless of HIV status. In people with HIV who developed high titre responses, predominantly those who were receptor-binding domain seropositive at enrolment, neutralising activity against beta was retained.InterpretationChAdOx1 nCoV-19 was well tolerated, showing favourable safety and immunogenicity in people with HIV, including heightened immunogenicity in SARS-CoV-2 baseline-seropositive participants. People with HIV showed cross-reactive binding antibodies to the beta variant and Asp614Gly wild-type, and high responders retained neutralisation against beta.FundingThe Bill & Melinda Gates Foundation, South African Medical Research Council, UK Research and Innovation, UK National Institute for Health Research, and the South African Medical Research Council.

<i>Background: </i>For unsuppressed viral load count, World Health Organization (WHO) currently encourages enhanced adherence counseling (EAC) for human immunodeficiency virus (HIV) seropositive people on antiretroviral therapy (ART) before switching the treatment to the second-line regimen. This study aimed to assess viral load suppression after EAC and its predictors among clients on ART. <i>Methods: </i>Institutional-based retrospective cohort study design was used to assess viral load suppression after EAC and its predictors among 175 high viral load and 175 virally suppressed HIV seropositive clients in selected public health centers at Lideta sub-city from November 2019 to December 2022. The magnitude of viral load suppression was determined by proportion. For comparing the probability of viral load suppression Kaplan–Meier curve was used. Cox-regression was used to identify predictors of viral resuppression after EAC. <i>Result:</i> The overall viral load suppression after EAC was 76.2% while viral load suppression among exposed and unexposed group were 72.6% and 80% respectively. The median time to complete the EAC of exposed group was 3 months. In this study, participants who were on ART for more than 12 months had more probability of viral load suppression (13-35 months AHR=6.586, 95% CI: 3.307-13.117, 36-59 months AHR=6.826, 95% CI: 4.316-10.796, ≥60 months AHR=6.596, 95% CI: 4.485-9.700) when compared with ART experience ≤ 12 months. Participants who had not disclosed their serostatus, had history of ART drug discontinuation, were free of opportunistic infection and daily laborer had more viral load suppression, too. <i>Conclusion:</i> This study showed that viral suppression after enhanced adherence counseling was greater than the WHO’s finding (70%) but still below United Nations’ 90-90-90 target. The study findings showed gaps in dalliance of completing recommended time of EAC with repeat viral load testing and needs another assessment with issue of groups’ comparison.

21 - Assessment of Young People and HIV Pandemia: Results from an Original Italian Questionnaire

BackgroundLeprosy remains an important public health problem in some specific high-burden pockets areas, including the Brazilian Amazon region, where it is hyperendemic among children.MethodsWe selected two elementary public schools located in areas most at risk (cluster of leprosy or hyperendemic census tract) to clinically evaluate their students. We also followed anti-PGL-I seropositive and seronegative individuals and households for 2 years to compare the incidence of leprosy in both groups.ResultsLeprosy was detected in 11 (8.2 %) of 134 school children in high risk areas. The difference in the prevalence was statistically significant (p < .05) compared to our previous findings in randomly selected schools (63/1592; 3.9 %). The 2-year follow-up results showed that 22.3 and 9.4 % of seropositive and seronegative individuals, respectively, developed leprosy (p = .027). The odds of developing overt disease in seropositive people were 2.7 times that of negative people (p < .01), indicating that a follow-up of 10 seropositives has a >90 % probability to detect at least one new case in 2 years. The odds of clinical leprosy were also higher in “positive houses” compared to “negative houses” (p < .05), indicating that a follow-up of ten people living in households with at least one seropositive dweller have a 85 % probability to detect at least one new case in 2 years.ConclusionsTargeted screening involving school-based surveillance planned using results obtained by spatial analysis and targeted household and individual continuous surveillance based on serologic data should be applied to increase the early detection of new leprosy cases.
