How Mobile Health Can Change the Contexts of Living With HIV and Engaging With Treatment and Care in Iran: A Realist-Informed Qualitative Study.

Mobile health (mHealth) interventions are increasingly used to address the challenges of living with HIV and engaging with antiretroviral therapy. A wealth of evidence supports the efficacy of mHealth in supporting living with HIV. Yet, there is a dearth of evidence on how mHealth improves outcomes, which features are effective, and why these work in a particular setting. This study uses stakeholder views, including patients, providers, peer supporters, counsellors, and program directors, to conceptualize how specific mHealth features could interact with contexts of living with HIV and mechanisms that shape engagement with treatment. The study is part of an ongoing research project on engagement with HIV care in Iran. We draw on the perspectives of recently diagnosed and more treatment-experienced patients and their providers, using purposive sampling, conducting 9 focus group discussions with a total of 66 participants, in addition to 17 interviews. Our findings suggest that mHealth designs that feature provider connection, proactive care, and privacy and personalization are expected to dilute the harsh contexts of living with HIV. We build on previously identified socioecological pathways that disrupt antiretroviral therapy in Iran and find that mHealth can enhance the relation between the health system and patients. Our findings suggest that personalized mHealth features and provisions can partially mitigate the compounded impacts of harsh socioecological pathways that impede treatment success in Iran. Our social constructivist study was augmented with realist-informed analysis and could have transferability to similar contexts that trigger similar mechanisms of treatment disruption.

The effectiveness of health-related quality of life (HRQOL) model in people with HIV: A cross sectional study.

Background and Aims: Acquired immune deficiency syndrome (AIDS) are a chronic and disabling disease that has a significant impact on quality of life due to weakening of physical health, financial problems and social stigma. This study aims to validate the Health-related quality of life (HRQOL) model in people with human immunodeficiency viruses (HIV) in Iran. Methods: Four hundred and fifty-two people with HIV from Imam Khomeini Hospital between the age of 18 and 65 years (men: 308, women: 144) participated in the research. anonymously completed a battery of questionnaires, namely the Persian basic psychological need satisfaction and frustration scale, SF-36, PSQI and mindful attention awareness scale. The method of the present study was the structural equation model. Results: Current findings indicated there is a significant positive between mindfulness and need satisfaction, physical and mental health and, significant negative between mindfulness and quality and quantity of sleep. Mindfulness and need satisfaction are significant positive predictors of quality of life in people with HIV. Quality and quantity of sleep are significant negative predictors of quality of life in people with HIV. There is a positive significance between need satisfaction and physical and mental health but there is a negative significance between need satisfaction and quality and quantity. there is a negative significant between the quality and quantity of sleep with physical and mental health. Mindfulness facilitates the satisfaction of more psychological needs and improves the quality of sleep. The quality of sleep is a negative significant predictor for physical and mental health but the quantity of sleep is a negative significant predictor for physical health. Conclusion: The HRQOL model can explain 18% of physical health and 16% of mental health in people with HIV in Iran. The elements of this model can be useful in evaluating and treating people with HIV in the Iranian Population. They also can use the models to plan for better services.

An empirical test of the chronic illness quality of life model: the prominent role of barrier to health care and social support.

The Chronic Illness Quality of Life (CIQOL) model highlights satisfaction with life in individuals with a chronic illness (i.e., HIV-related diseases) determined by factors such as barriers to health care, AIDS-related discrimination, social support, physical well-being, and engagement coping. Despite the empirical evidence supporting the CIQOL model, its validation in the Iranian population has not yet been conducted. This study aimed to validate the CIQOL model among Iranian patients with HIV-related diseases. Four hundred fifty-two patients completed the study questionnaire including Barriers to Care Scale (BACS), Satisfaction with Life Scale (SWLS), Chronic Illness Anticipated Stigma Scale (CIASS), Social Provision Scale (SPS), The Functional Assessment of Human Immunodeficiency Virus Infection (FAHI), and the Brief COPE Scale. Structural equation modeling (SEM) was used to analyze the data. The assumed model demonstrated an acceptable level of fit to study data. Findings showed that this model could explain 39% of variances in life satisfaction in Iranian patients with HIV-related diseases. Therefore, in psychological interventions aimed at enhancing life satisfaction, the CIQOL model factors especially barriers to health care and social support can be taken into consideration.

Risky Sexual Behaviors and Condom Use Barriers in Iranian Women with Substance Use Disorders.

Background: Scant information exists on Iranian women's protective behaviors mainly constant condom use. Inconsistent condom use seems prevalent among women with substance use problems. We aimed to investigate risky sexual behaviors (RSBs) and condom use barriers in Iranian women with substance use disorders (SUDs). Methods: In our cross-sectional study, we recruited 300 women who sought treatments for their SUDs from the active outpatient drug free (ODF) and Methadone Maintenance Therapy (MMT) centers in Tehran, Iran during 2017-2021. We used three batteries including demographic questionnaire, the Risky Sexual Behavior Questionnaire (RSBQ); and the Condom Barriers Scale (CBS). The statistical software R, analysis of variance post hoc and multivariate analysis of variance (MANOVA) logistic regression tests were used in data analysis. Results: The majority reported at least one lifetime experience of RSBs. Our results show that only 22% of the participants 'always' use condom in their sexual encounters. The lowest and highest subscale scores of the CBS were related to Sexual Experience (SE) (2.47 ± 0.86) and access/availability structure (3.52 ± 0.7), respectively. RSBs had negative significant association with Partner Barrier (PB) subscale scores (OR = 0.4; 95% CI: 0.22 to 0.73) and effect on SE subscale scores (OR= 0.54; 95% CI: 0.31 to 0.94). Conclusion: RSBs was prevalent among our study population. RSBs and condom use barriers are significantly interwoven. The condom use barriers were highly associated with the types of sexual encounters such as group sex or casual sexual relations than specific mean of sexual performance (i.e. anal sex). Gender-specific RSBs, STIs/HIV/AIDS prevention program is recommended for women with SUDs.

Efficacy and safety of an inactivated virus-particle vaccine for SARS-CoV-2, BIV1-CovIran: randomised, placebo controlled, double blind, multicentre, phase 3 clinical trial.

OBJECTIVE: To report the efficacy, safety, and exploratory immunogenicity findings of two 5 µg doses of the BIV1-CovIran vaccine. DESIGN: Randomised, placebo controlled, double blind, multicentre, phase 3 clinical trial. SETTING: In six cities of Iran, including Bushehr, Isfahan, Karaj, Mashhad, Shiraz, and Tehran. The first vaccine or placebo injection of the first participant was on 16 May 2021 in Tehran. The last vaccine or placebo injection of the last participant occurred on 15 July 2021 in Isfahan. PARTICIPANTS: 20 000 participants aged 18-75 years were randomly assigned to the intervention or placebo groups with a ratio of 2:1. INTERVENTION: 5 µg vaccine or placebo with the interval of 28 days. MAIN OUTCOME MEASURES: Vaccine efficacy for a 90 day follow-up period, safety and explanatory immunogenicity assessment, and variant detection during the trial. RESULTS: 20 000 participants were recruited and randomly assigned to receive BIV1-CovIran (n=13 335 (66.7%)) or placebo (n=6665 (33.3%)). Participants' mean age was 38.3 (standard deviation 11.2) years, and 6913 (34.6%) were female. Among vaccinated participants that had covid-19 reported during the follow-up (median 83 days), 758 (5.9%) had symptoms, 144 (1.1%) had severe infection, and seven (0.1%) were critical. Among participants who received placebo during the follow-up, 688 (10.7%) had symptoms, 221 (3.4%) had severe infection, and 19 (0.3%) were critical. Overall efficacy was 50.2% (95% confidence interval 44.7% to 55.0%) against symptomatic covid-19, 70.5% (63.7% to 76.1%) against severe disease, and 83.1% (61.2% to 93.5%) against critical cases. Two deaths were reported in the efficacy population in the placebo group, no deaths were from the intervention group. During follow-up, 41 922 adverse events were reported: 28 782 (68.7%) were adverse reactions, of which 19 363 (67.3%) were in the intervention group. Most adverse reactions were mild or moderate in severity (grade 1 or 2) and self-limiting. No serious adverse events were related to the injections. For variant investigation, of 119 participants positive for the SARS-CoV-2 variant, 106 (89.1%) were positive for the delta variant. CONCLUSIONS: A two dose regimen of the BIV1-CovIran vaccine conferred efficacy of 50.2% against symptomatic covid-19, 70.5% against severe disease, and 83.1% against critical disease. Vaccination was well tolerated, with no safety concerns raised. TRIAL REGISTRATION: Iranian Registry of Clinical Trials, IRCT20201202049567N3. FUNDING: Shifa-Pharmed Industrial Group.

Gamified Educational Learning Path on HIV/AIDS Stigma and Discrimination (REDXIR): Design, Development and Pilot Study.

Background: HIV/AIDS-related stigma and discrimination are among the main barriers to controlling the HIV epidemic. Discriminatory behavior in healthcare settings deprives people of accessing high-quality health services. Methods: This study presents the design, development, and pilot study of a novel web-based application ("REDXIR"), which is designed based on behavioral and gamification principles and aims to eliminate HIV/AIDS-related discriminatory behavior among health professions students. REDXIR storyline is set in an imaginary world where the students' journey is like a 10-level game, in which each level consists of several missions with a certain amount of score. The participants have to accomplish the mission to reach the minimum amount of score to pass each level. Finally, each becomes an individual who has not only the knowledge but also the competency to educate and advocate appropriately in the field. Results: The pilot was done in six medical sciences universities in Tehran, Iran. The feasibility of the instructional design, specifically gamification strategies in the field of HIV education, and the executive functions to run the program on a bigger scale were evaluated. In total, 241 students were included and performed 1952 missions. The program evaluation showed a mean satisfaction score of 4.16 (from 1, the lowest, to 5, the highest) and participants considered their learning practical and gamification method appropriate for HIV education. Conclusion: A meaningful gamification design for an online medical education program could be a suitable, functional, and applicable learning model to reduce HIV/AIDS stigma and discrimination among health professions students.

Relationships among COVID-19 phobia, health anxiety, and social relations in women living with HIV in Iran: A path analysis.

INTRODUCTION: The COVID-19 pandemic and its consequences have caused fear and anxiety worldwide and imposed a significant physical and psychological burden on people, especially women living with HIV (WLHIV). However, WLHIV were not studied as well as others during the pandemic. Hence, this study aimed to determine the relationships between COVID-19 phobia, health anxiety, and social relations in WLHIV. MATERIALS AND METHODS: This cross-sectional study enrolled 300 WLHIV who had records at the Iranian Research Center for HIV/AIDS of Tehran University of Medical Sciences. Data were collected using sociodemographic questionnaire, the fear of COVID-19 scale, the social relations questionnaire, the socioeconomic status scale and the health anxiety inventory. Path-analysis was used to assess the direct and indirct associations between variables. RESULTS: Based on the path analysis, among variables that had significant causal relationships with social relations, socioeconomic status (ß = -0.14) showed the greatest negative relationship, and health anxiety (ß = 0.11) had the strongest positive relationship on the direct path. On the indirect path, fear of COVID-19 (ß = 0.049) displayed the greatest positive relationship. The level of education (ß = 0.29) was the only variable showing a significant positive relationship with social relations on both direct and indirect paths. CONCLUSION: Our result showed that increased fear and health anxiety related to a higher social relations score in WLHIV. Hence, due to their vulnerability, these people require more support and education to adhere to health protocols in future pandemics and similar situations.

Immediate and Long-Term Effects of a Computerized Cognitive Rehabilitation Therapy on Cognitive Function in People Living with HIV in Iran: A Single-Blind Two-Arm Parallel Randomized Controlled Trial.

ABSTRACT: Up to 50% of people with HIV (PWH) experience neurocognitive impairments (NCIs) that can interfere with everyday functioning and reduce quality of life. To address this problem, this study examined the immediate and long-term efficacy of computerized cognitive rehabilitation therapy (CCRT) on cognitive function in PWH in Tehran, Iran. Thirty PWH with NCI engaged in 24 biweekly 90-min CCRT sessions. A control group of 30 PWH and NCI received treatment-as-usual, but no CCRT. The cognitive rehabilitation protocol focused on attention, visual memory, nonverbal learning, and planning. Pretest, posttest, and follow-up cognitive measurements showed that the designed CCRT protocol was effective in improving performance in selected cognitive domains along with the global neurocognitive performance scores of PWH. These findings suggest that this CCRT protocol be considered as part of a treatment plan to address cognitive impairment for PWH. Implications for clinical practice and research are provided.

A case report of ulceroglandular tularemia caused by Francisella tularensis subsp. Holarctica in Iran.

BACKGROUND: Tularemia is a zoonotic disease that has been reported in many countries of the Northern Hemisphere. However, in some countries, such as Iran, this disease has been neglected by the health care system, and it is under-reported. CASE PRESENTATION: Here we report an unusual case of ulceroglandular tularemia occurring in a 35-year-old woman who presented with a skin lesion of the left flank, inguinal lymphadenopathy, and an abdominal abscess. The serological and real-time PCR tests for tularemia were positive for this patient, and infection by Francisella tularensis subsp. holarctica was confirmed. CONCLUSIONS: It is necessary to implement various educational programs to increase the awareness of physicians with tularemia.

Safety and immunogenicity of an inactivated virus particle vaccine for SARS-CoV-2, BIV1-CovIran: findings from double-blind, randomised, placebo-controlled, phase I and II clinical trials among healthy adults.

OBJECTIVE: Assessing safety and immunogenicity of an inactivated whole virus particle vaccine. DESIGN: Single-centre, double-blind, randomised, placebo-controlled, phase I (stage I: 18-50, stage II: 51-75 years), phase II (18-75 years) clinical trials. SETTING: 29 December 2020 to 22 April 2021. PARTICIPANTS: Stage I-phase I: 56 participants; stage II-phase I: 32; phase II: 280. INTERVENTION: During stage I, participants randomly (3:3:1) received 3 µg, 5 µg vaccine or placebo in a 14-day interval. Participants in stage II received two shots of 5 µg vaccine or placebo (3:1). In phase II, participants received 5 µg vaccine or placebo (4:1) in a 28-day interval. PRIMARY AND SECONDARY OUTCOME MEASURES: Safety assessment and immunogenicity assessment via antibody response and conventional virus neutralisation test (cVNT). RESULTS: All adverse events (AEs) were mild or moderate and transient in both phase I and phase II, and no AEs of special interest were reported. The seroconversion-rate of neutralising, antireceptor binding-domain (RBD) and anti-spike-glycoprotein (anti-S) antibodies 14-days after second dose of 5 µg vaccine in stage I was 70.8% (95% CI 48.9% to 87.4%), 87.5% (95% CI 67.6% to 97.3%), 91.7% (95% CI 73.0% to 99.0%). The antibody titres increased more among 5 µg than 3 µg. The corresponding rates for 3 µg vaccine were 45.8% (95% CI 25.6% to 67.2%), 54.2% (95% CI 32.8% to 74.5%) and 70.8% (95% CI 48.9% to 87.4%), respectively. In stage II, 100% (95% CI 84.6% to 100%), 86.4% (95% CI 65.1% to 97.1%) and 86.4% (95% CI 65.1% to 97.1%) of participants seroconverted for neutralising, anti-RBD and anti-S antibodies. In phase II, the seroconversion rate of neutralising-antibody was 82.8% (95% CI 77.0% to 87.6%), anti-RBD 77.0% (95% CI 70.7% to 82.6%) and anti-S 79.9% (95% CI 73.8% to 85.1%) on day 42. In the cVNT, the sera at 1/64 times dilution would neutralise SARS-CoV-2 among 91.7%, 77.3% and 82.5% of vaccinated participants in phase I-stage I, phase I-stage II and phase II clinical trials, respectively. CONCLUSIONS: These results support further evaluation of this inactivated whole virus particle vaccine. TRIAL REGISTRATION NUMBERS: IRCT20201202049567N1 and IRCT20201202049567N2 for phase I and IRCT20201202049567N3 for phase II.

Assessment of BIV1-CovIran inactivated vaccine-elicited neutralizing antibody against the emerging SARS-CoV-2 variants of concern.

OBJECTIVES: The BIV1-CovIran vaccine is highly effective against COVID-19. The neutralizing potency of all SARS-CoV-2 vaccines seems to be decreased against variants of concern. We assessed the sensitivity of the Alpha (B.1.1.7), Beta (B.1.351), and Delta (B.1.617.2) variants to neutralizing antibodies (NAbs) present in sera from individuals who had received the BIV1-CovIran candidate vaccine compared with an original Wuhan-related strain. METHODS: The ability of vaccine serum to neutralize the variants was measured using the conventional virus neutralization test. The correlation of spike (S) protein antibody and anti-receptor binding domain with neutralizing activity was investigated. RESULTS: The current study demonstrated that 29 of 32 (90.6%; 95% CI: 75.0-98.0) of the vaccinees developed NAbs against a Wuhan-related strain. It is noteworthy that 28 (87.50%) and 24 of 32 (75%) of the recipients were able to produce NAbs against Alpha, Beta, and Delta variants, respectively. Serum virus-neutralizing titres for different SARS-CoV-2 strains were weakly correlated with anti-receptor binding domain antibodies (Spearman r = 36-42, p < 0.05), but not S-binding antibodies (p > 0.05). DISCUSSION: Although there was a reduction in neutralization titres against the Alpha, Beta, and Delta variants compared with the Wuhan strain, BIV1-CovIran still exhibited potent neutralizing activity against the SARS-CoV-2 variants of concern.

Prevalence, Demographic Correlates, and Medical Correlates of Cognitive Impairment Among Iranian People Living With HIV: A Cross-sectional Survey Study.

ABSTRACT: While taking antiretroviral therapy, 30%-60% of people living with HIV (PLWH) experience neurocognitive impairment (NCI). To determine NCI prevalence among Iranian PLWH, by the computerized Vienna Test System, 63 adults living without HIV and 63 Iranian PLWH aged 18-50 years ( M = 35.3, SD = 7.9) were assessed for cognitive function. NCI was determined by receiver operating characteristic curve cutoff points based on the adults living without HIV. Associations between demographics, HIV serostatus markers, and mean T-scores were investigated. Performance differences were tested by including significant covariates in an analysis of covariance. NCI prevalence rates were 57.14% in PLWH and 19.05% in adults living without HIV. Global neurocognitive performance and all cognitive domains were significantly different between the groups, except for visual memory and selective attention. In Iran, NCI prevalence parallels that reported in PLWH worldwide. There should be a strategy to screen Iranian PLWH for NCI.

'You just prefer to die early!': how socioecological context impedes treatment for people living with HIV in Iran.

INTRODUCTION: Despite the low prevalence of HIV and broad provision of antiretroviral therapy, the Middle East and North Africa (MENA) remains the only region where new HIV infections and AIDS-related deaths are not declining. There is a dearth of evidence from MENA on antiretroviral therapy engagement. In this qualitative study, we sought to identify the ways in which successful treatment is hindered in Iran, which is home to 24% of HIV infections in MENA. METHODS: From August 2018 to January 2019, we used purposive sampling and conducted 12 individual interviews and 8 focus group discussions with 27 female and 31 male patients, in addition to 5 individual interviews with HIV care providers and 1 focus group discussion with 8 care providers. Social constructivism augmented with realist-informed thematic analysis was used to understand how the socioecological context triggers cognitive and affective mechanisms that disrupt antiretroviral therapy. RESULTS: The use of Thematic Network Analysis resulted in the identification of three key cognitive and affective mechanisms that appear to shape treatment experience and are triggered via HIV's socioecological context and changing economic conditions in Iran: denial in response to societal negative perceptions of HIV; fear in response to societal lack of awareness regarding HIV and misinformation; and despair in response to HIV-related stigma and enacted discrimination, economic insecurity and social support. CONCLUSIONS: To our knowledge, this is the first study within MENA to identify pathways through which successful treatment is hindered. It appears that lack of societal awareness regarding HIV is specific to low prevalence settings, such as MENA countries, where negative perceptions, stigma, discrimination and misinformation regarding HIV and its treatment produce denial, fear and despair, acting as mechanisms that disrupt antiretroviral therapy. The experience of despair, in response to changing economic conditions and social support, further impacts treatment experience.

Tailored mHealth intervention for improving treatment adherence for people living with HIV in Iran (HamRaah): protocol for a feasibility study and randomised pilot trial with a nested realist evaluation.

INTRODUCTION: Middle East and North Africa (MENA) has a rising rate of new HIV infections and AIDS-related mortality. Consistent adherence to antiretroviral therapy (ART) leads to viral suppression, preventing HIV transmission and treatment failure. mHealth interventions can improve ART adherence by providing tailored support and directing patients to existing healthcare services. HamRaah (Persian for 'together-in-path') is the first mHealth-based intervention in a MENA country and is designed to improve adherence through two-way mobile messaging for people recently diagnosed with HIV in Tehran, Iran. The objectives of this pilot randomised controlled trial (RCT) are to examine the feasibility, acceptability and preliminary effectiveness of HamRaah, and to develop an explanatory theory for any observed effects through a nested realist evaluation. METHODS: A feasibility study and two-arm RCT of HamRaah, with an embedded realist evaluation will be conducted. Participants will be randomised 1:1 to HamRaah or routine care for a 6-month intervention. The initial effectiveness of HamRaah will be assessed through the primary outcome of self-reported ART adherence and several secondary outcomes: retention in care, CD4 count and viral suppression. A theory-driven realist evaluation framework will be used to develop an explanatory theory regarding what works, for whom, how and in what context. ETHICS AND DISSEMINATION: The study received ethical clearance from Tehran University of Medical Sciences Ethics Committee and Oxford Tropical Research Ethics Committee People living with HIV in Tehran and key country stakeholders in HIV policy and programming have been involved in the development of HamRaah and this pilot trial. Participants will provide informed consent prior to study enrolment. The results will be disseminated to all stakeholders and presented in peer-reviewed journal publications and conferences. TRIAL REGISTRATION NUMBER: IRCT20100601004076N23; Pre-results.

Clinical outcomes of patients with mild COVID-19 following treatment with hydroxychloroquine in an outpatient setting.

The role of hydroxychloroquine (HCQ) in early outpatient management of mild coronavirus disease 2019 (COVID-19) needs further investigation. This study was a multicenter, population-based national retrospective-cohort investigation of 28,759 adults with mild COVID-19 seen at the network of Comprehensive Healthcare Centers (CHC) between March and September 2020 throughout Iran. The baseline characteristics and outcome variables were extracted from the national integrated health system database. A total of 7295 (25.37%) patients who presented with mild COVID-19 within 3-7 days of symptoms onset received HCQ (400 mg twice daily on day 1 followed by 200 mg twice daily for the next four days and were then followed for 14 days). The main outcome measures were hospitalization or death for six months follow-up. COVID-19-related hospitalizations or deaths occurred in 523 (7.17%) and 27 (0.37%) respectively, in HCQ recipients and 2382 (11.10%) and 287 (1.34%) respectively, in non-recipients. The odds of hospitalization or death was reduced by 38% (odds ratio [OR] = 0.62; 95% confidence interval [CI]: 0.56-0.68, p = < 0.001) and 73% (OR = 0.27; 95% CI: 0.18-0.41, p = < 0.001) in HCQ recipients and non-recipients. These effects were maintained after adjusting for age, comorbidities, and diagnostic modality. No serious HCQ-related adverse drug reactions were reported. In our large outpatient national cohort of adults with mild COVID-19 disease who were given HCQ early in the course of the disease, the odds of hospitalization or death was reduced significantly regardless of age or comorbidities.

Single-pill sofosbuvir and daclatasvir for treating hepatis C in patients co-infected with human immunodeficiency virus.

BACKGROUND: The current recommendation for treating hepatitis C virus (HCV) in HIV patients includes the combination of sofosbuvir (SOF) and daclatasvir (DCV). DCV should be used at different doses to compensate for interactions with antiretroviral therapy (ART). Up to three pills a day might be required which will significantly add to the pill burden of these patients. In this study, we have used a single-tablet approach to treating HCV-HIV coinfection. METHODS: Patients coinfected with HIV and HCV were prospectively enrolled from 10 centers throughout the country. Patients received a single once-daily fixed dose combination (FDC) pill containing 400 mg SOF and 30, 60 or 90 mg DCV depending on the type of ART they were receiving for 12 or 24 weeks. (ClinicalTrials.gov ID: NCT03369327). RESULTS: Two hundred thirty-three patients were enrolled from 10 centers. Twenty-three patients were lost to follow-up and two patients died from causes unrelated to treatment. Two hundred eight patients completed the treatment course of which 201 achieved SVR (96.6%). CONCLUSION: Single-tablet combination of DCV and SOF is an effective and safe treatment for patients coinfected with HIV and HCV. The combination works well in patients on ART in which dose adjustment is required. Patients with cirrhosis, previous treatment failure and various genotypes respond identically. The expenses of genotyping can be saved.

Sociodemographic Characteristics, HIV-Related Risk Behaviors and HIV Prevalence of Vulnerable Men in Tehran, Iran.

BACKGROUND: Sexual minorities, such as men who have sex with men (MSM), are disproportionately impacted by HIV/AIDS compared to heterosexual men. The increased prevalence of HIV/AIDs among this group of individuals is associated with increased participation in HIV-related risk behavior, such as multiple sexual partnerships and injection drug use. However, very little is known about the prevalence of HIV and the risk behaviors related to HIV infection among MSM in Iran. This absence of data is due to the increased discrimination and stigmatization MSM, and other vulnerable populations face in Iran. This study was conducted to identify HIV-related risks, HIV prevalence and sociodemographic characteristics of the MSM population in Iran. METHODS: A cross-sectional study was conducted among MSM attending the Sexual Health Clinic at Imam Khomeini Hospital in 2018. A sexual health screening questionnaire was used to aid in identifying HIV-related risk behaviors. HIV status was determined using an HIV rapid test and confirmed by an ELISA. RESULTS: One hundred MSM enrolled in this study, out of which 41% were 18-25 years old. The majorities were single; almost one-third had a diploma degree. Only a fifth were employed, and about a quarter (25%) reported substance abuse. Among eighty-three people (83%) reported having sex during the past three months, and only 27 (27.3%) of participants always used condoms for sex. Among 80 participants tested for HIV, two positive results were detected (2.5%). CONCLUSION: Data collected through a sexual health questionnaire indicated that the prevalence of HIV is increased among MSM in Iran. This finding sheds light on the urgent need for the implementation of social programs providing counseling and healthcare to vulnerable populations in Iran.

Frequency of Cytomegalovirus Viral Load in Iranian Human Immunodeficiency Virus-1-Infected Patients with CD4+ Counts <100 Cells/mm3.

OBJECTIVES: The aim of present work was to assess cytomegalovirus (CMV) viremia in Iranian human immunodeficiency virus (HIV)-1-infected patients with a CD4+ count <100 cells/mm3 and to explore whether CMV DNA loads correlate with CD4+ cell counts or associated retinitis. METHODS: This study was conducted at the AIDS research center in Iran on HIV-1-infected patients with CD4+ count <100 cells/mm3, antiretroviral therapy-naive, aged ≥18 years with no previous history of CMV end-organ disease (CMV-EOD). RESULTS: Thirty-nine of 82 patients (47.56%) had detectable CMV viral load ranging from 66 to 485,500 IU/mL. CMV viral load in patients with retinitis ranges from 352 to 2,720 IU/mL, and it was undetectable in 2 patients. No significant associations between CMV viremia and CD4+ cell count was found (p value = 0.31), whereas significant association of CMV viremia in HIV-infected patients with retinitis was found (p < 0.02). CONCLUSIONS: We estimated the frequency of CMV viral load infection in Iranian HIV-1-infected patients with a CD4+ cell count <100 mm3/mL in the largest national referral center for HIV-1 infection in Iran. Further research is required on the relevance of CMV viral load in diagnostic and prognostic value of CMV-EOD.

Expression of mir-221, mir-29a, mir-155 and mir-146a in Peripheral Blood Mononuclear Cell (PBMC) in HIV-1 Infected Patients.

AIMS AND OBJECTIVES: In patients infected by HIV-1, some cellular biomarkers such as microRNAs have an important function in the suppression or progression of the disease. The aim of the current study is to evaluate the expression of mir-221, mir-29a, mir-155, and mir-146a in HIV-1 infected patients. METHODS: The miRNAs of 60 HIV-1 infected patients (sample group) and 20 healthy controls (normal group) were extracted from their peripheral mononuclear cells. We used TaqMan-based Real-- time PCR for evaluation of expression mir-155, mir-221, mir-29a and mir-146a by the comparative method. To evaluate differences among the data, one-way ANOVA was used. The expression of mir-155 and mir-146a in HIV-1 patients (sample group) was down-regulated in comparison with healthy controls (normal group) with a confidence value (p <0.001). In addition, in the sample group, the expression of mir-221 was downregulated compared to the normal group (p <0.001). RESULTS: There was no significant difference in expression mi-29a in the sample and control group. In the sample group, mir-221 had a low expression, and mir-29a had a high expression, respectively. According to the results of the current study and comparative studies, it seems that the microRNA has an important role in the progression or suppression of HIV-1 infection. CONCLUSION: However, the data showed that besides other cellular and viral factor, these miRNAs could be used as a biomarker. However, the miRNAs field experts are in general agreement that more investigation is needed to use miRNAs as a biomarker in HIV.

Combination of resistance and aerobic exercise for six months improves bone mass and physical function in HIV infected individuals: A randomized controlled trial.

To evaluate the effect of combined resistance and aerobic training (RT+AT) on regional bone mineral density (BMD) and physical performance in people living with HIV (PLWH). Forty PLWH (20 men and 20 women) were randomized into RT+AT group (n = 20; age = 38.3 ± 4.9) or non-exercise control group (n = 20; age = 37.9 ± 5.1). The RT+AT group was required to perform a nonlinear periodized resistance training program targeting large muscle groups followed by 20 min aerobic exercise at 65-80% of maximal heart rate. Participants in RT+AT performed three supervised sessions per week for 6-months, whereas participants in the control group were instructed to continue with their current lifestyle habits. The primary outcome was bone mineral density (lumbar spine (L2-L4), femoral neck, and distal 1/3 radius). Secondary outcomes included physical function, anthropometry, inflammatory markers, and growth factors. The RT+AT group demonstrated a significant increase in BMD at follow-up for the Lumbar spine (L2-L4), femoral neck, and 1/3 radius (all, P < .05), and There were no gender differences in the training response between men and women for any of the BMD regions. Similar findings were also observed for lean body mass, IGF1and Adiponectin (P < .001). We observed a decrease in percent body fat, fat mass, IL-6, TNF-α, and myostatin in the RT+AT group (P < .001). Finally, there was a significant increase in handgrip strength and gait speed for both women and men in the RT+AT group (P < .001). A combination of resistance and aerobic training appears to be a feasible and effective means for counteracting bone loss and improving various inflammatory markers, physical function, and growth hormones in PLWH.
