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.

HIV Prevalence and Sexual Behaviors Among Transgender Women in Tehran, Iran.

To date, no study has looked at the prevalence of HIV and the high-risk behaviors among transgender women in Iran. Between May 2013 and February 2014, 104 transgender women were recruited for participation in this study. Inclusion criteria consisted of having an official letter from the Tehran Psychiatric Institute, or a well-known psychiatrist, that showed a diagnosis of gender dysphoria and/or completed Gender-Affirming Surgery at least 6 months prior to this study. Of the 104 participants, 2 were diagnosed with HIV, which translates to a HIV prevalence of 1.9%. Condom use with a non-paying partner, casual partner, and paying partner was respectively 39.7%, 34.6%, and 53.3%. A high percentage of transgender women in Tehran engage in high-risk sexual behaviors including condomless receptive anal sex, which is of particular concern given the low rates of HIV testing. Targeted public intervention programs and research are desperately needed for this high-risk group.

HBsAg mutations related to occult hepatitis B virus infection in HIV-positive patients result in a reduced secretion and conformational changes of HBsAg.

BACKGROUND: Occult hepatitis B infection (OBI) is a frequent finding in human immunodeficiency virus (HIV)-infected patients. While several related mutations in the hepatitis B virus (HBV) genome have been reported, their distinct impact on HBsAg synthesis is largely obscure. METHODS: Thirty-one (18%) out of 172 HIV-infected patients, who were selected from HBsAg-negative patients, were positive for HBV-DNA assigned as being OBI-positive. We generated a series of expression constructs of variant HBsAg with "a" determinant amino acid substitutions including P127L, P127T, S136Y, and P127T + S136Y using site-directed mutagenesis. The expression of variant HBsAg was examined by transient transfection in hepatoma cells, followed by HBsAg immunoassay and immunofluorescence stained with specific anti-HBs antibodies. The potential impact of amino acid substitutions at different positions for conformational changes in the HBsAg was investigated using bioinformatics. RESULTS: All variants comprising either single or combined mutations resulted in significantly reduced HBsAg detection in supernatants and in cell lysates of hepatoma cells transfected with the constructs. Moreover, intracellular immunofluorescence staining of cytoblocks showed perinuclear and cytoplasmic fluorescence of HBsAg constructs with significantly diminished fluorescent intensity in comparison to the wild type. Altered protein conformations by predictive models, indicating an impaired detection by the host's immune response as well as by commercial antibody-based test assays. CONCLUSION: Mutations in the "a" determinant region of HBV as often found in OBI remarkably impair the detection of HBsAg from serum and infected cells, emphasizing the relevance of alternative methods such as HBV-DNA quantification for high-risk groups like HIV-infected individuals.

Evaluating the Relationship between Various Risk Factors and COVID-19 Incidence In People Living with HIV: A Cross-Sectional Study.

INTRODUCTION: People living with HIV (PLWH) are more susceptible to acquiring and having serious consequences from COVID-19. The objective of this study was to examine the correlation between COVID-19 infection and other risk factors in these patients. METHODS: This is a descriptive-analytical study recruiting 160 PLWH referred to the Behavioral Disease Counselling Centre of Imam Khomeini Hospital in Tehran in 2021. The patients were selected through convenient sampling. A checklist was used to collect the necessary data. Descriptive statistical tests, such as mean and standard deviation, were employed alongside inferential statistics, including chi-square, Fisher, independent t-tests, and logistic regression, all evaluated at a significance level of p<0.05 using the R software. RESULTS: The patients' average age was 43.15 ± 11.23. Forty-four women and 116 men were present. A notable association was observed between the incidence of COVID-19 and variables such as hepatitis C and the duration of time since HIV diagnosis (p<0.001). Moreover, a strong correlation was found between the amount of COVID-19 vaccination doses given to patients and their probability of acquiring the disease. The first vaccination dose was linked to a 5.45 percent increase in COVID-19 incidence in patients, whereas the second and third doses (t=2.95, t=7.57) reduced the risk of getting COVID-19. Furthermore, no discernible link (p>0.05) was found between the use of various antiretroviral medications and COVID-19 infection. CONCLUSION: This study finds that vaccine type doesn't impact COVID-19 outcomes in HIV-positive patients, but receiving more doses decreases the probability of occurrence of COVID-19, advocating for multiple vaccinations. However, PLWH, especially those non-compliant with antiretrovirals, need strict adherence to health protocols due to heightened vulnerability to viral illnesses.

Prevalence of and risk factors for HCV among incarcerated people at Great Tehran Prison: a cross-sectional study.

PURPOSE: Hepatitis C is one of the major health issues in both developed and developing countries. Hepatitis C virus (HCV) infection is more common in prisoners than in the general population. The purpose of this study was to determine the prevalence of HCV and its associated risk factors in Iranian male prisoners in Tehran. DESIGN/METHODOLOGY/APPROACH: In this cross-sectional study, the authors investigated the frequency and risk factors of hepatitis C infection among male prisoners in the Great Tehran Prison. Information on risk factors including the length of imprisonment, previous history of imprisonment, history of drug injection, history of tattooing, history of piercing, history of high-risk sex and family history of hepatitis C were extracted from patients' records. To evaluate HCV status, blood samples were collected and tested. FINDINGS: In this study, 179 participants were included. Nine participants (5.0%, 95% CI, 2.3-9.3) were positive for hepatitis C. HCV infection was not significantly associated with age, marital status, education, previous history of imprisonment, length of imprisonment, piercing and high-risk sex; however, there was a significant association between a history of tattooing and a history of injecting drug use and Hepatitis C. ORIGINALITY/VALUE: The prevalence of hepatitis C among male prisoners in Great Tehran Prison was 5% in this study, similar to recent studies on prisoners in Tehran. A history of drug injections as well as tattooing were the most important risk factors for hepatitis C in male prisoners.

Famotidine's Possible Cutaneous Rash in COVID-19 Patients: An Adverse Effect Case Series.

BACKGROUND: Various cutaneous manifestations have been observed in patients with COVID-19 infection. However, the side effects on skin of the medications used for COVID-19, such as famotidine, have not been studied. OBJECTIVE: This case series aims to present challenges in defining cutaneous manifestations of famotidine in the context of COVID-19. CASE PRESENTATION: We identified patients from Imam Khomeini hospital complex who were admitted to the ward due to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), were taking famotidine and having cutaneous rash. Clinical data were obtained through observation and intervention. DISCUSSION: We found 4 SARS-CoV-2 patients with cutaneous manifestations. The mean (±SD) age of the patients was 57±2 years, 3 patients were men, and their COVID-19 symptoms appeared 10±3 days before admission. The most common symptoms were cough and shortness of breath. All the patients were admitted for hypoxemic respiratory failure. Patients received famotidine for gastrointestinal prophylaxis, and all 4 patients developed Acral macular mountainous skin lesions in the upper and lower extremities, then we discontinued famotidine and lesions were recovered completely in all patients. CONCLUSION: These cases prompted us to inform clinicians about cutaneous complications of famotidine in COVID-19 patients.

Bone Marrow Aspiration/Biopsy in the Evaluation of Fever of Unknown Origin in Patients with AIDS.

BACKGROUND: HIV can interrupt the normal development of bone marrow cell lines. Bone marrow aspiration/biopsy (BMA/B) has been described as a diagnostic tool in AIDS patients with fever of unknown origin (FUO). In this review, we aimed to study patients with AIDS who had undergone a BMA/B to investigate FUO and describe the pathologies diagnosed in the biopsy. METHODS: Thirty-four BMA/B samples were collected from AIDS patients admitted for work-up of FUO to the infectious disease ward of a tertiary referral HIV center in Tehran, Iran, between September 2014 and September 2015. Data including age, sex, duration of disease, CD4 cell counts, hepatitis B (HBV) and C (HCV) coinfection, the primary presentation of AIDS, and the treatment history were retrieved and analyzed. Patients underwent BMA/B. An expert pathologist reviewed the BMA/B specimens. RESULTS: The mean age of the patients was 37.5 years (range, 26-56), and 27 (79%) were men. Twenty-seven (79%) patients contracted HIV from injection drug use, and 7 (21%) via sexual transmission. Only 3 (9%) of the BMA/B examinations were normal. Hypocellular bone marrow was diagnosed in 22 (65%) patients. Other pathologies included granulomas in 6 (18%), hematologic malignancies in 2 (6%), and leishmaniasis Aspergillosis, each in 1 (3%) patient. Six (17%) of the specimens were found to have tuberculosis infections. CONCLUSION: Hypocellular bone marrow was the most common pathology on BMA/B examinations, followed by the presence of granulomas. Tuberculosis, Aspergillosis, and Leishmaniasis the opportunistic infections diagnosed on BMA/B specimens. Our results support BMA/B as an appropriate diagnostic tool for early diagnosis of opportunistic infections and malignancies in AIDS. BMA/B is indispensable in the armament of diagnostic tools of the physicians managing AIDS patients.

Genotyping and Drug Susceptibility Patterns of M. Tuberculosis Isolated from HIV Seropositive Patients in Tehran Iran.

AIM: This study aims to investigate the prevalence and drug-resistance M. tuberculosis isolated from HIV seropositive individuals in Tehran, Iran. BACKGROUND: Human immunodeficiency virus (HIV) is one of the most important risk factors for developing active tuberculosis (TB). OBJECTIVE: The objective is to determine the rate of transmission and drug-resistant M. tuberculosis (MTB) strains isolated from HIV seropositive patients in Tehran province, Iran. METHODS: This study consecutively enrolled 217 TB/HIV coinfected patients from April 2018 to August 2019 at Emam Khomeini referral hospital and 5 other health centers in Tehran province. The isolates were genotyped using 15 loci Mycobacterial interspersed repetitive unit-variable number tandem repeats (MIRU-VNTR). Minimum inhibitory concentration (MIC) was determined for 6 drugs. In addition, mutations were assessed in rpoB, katG, inhA, and ahpC genes using Reverse Blot Hybridization Assay System. RESULTS: A 20 (9.2%) patients were culture-positive for M. tuberculosis and typed by MIRU-VNTR, 13 (65%) strains formed 5 clusters, but 6 (30%) isolates had a unique pattern. The total Hunter- Gaston discrimination index (HGDI) for all 15 loci was 0.846, and the cluster size was 2 to 4 patients. The estimated proportion of recent transmission was 45%. The mutation was identified in 1 isolate, lost inhAW1 and mutation in MT1 loci, which was resistant to isoniazid (INH). Moreover, 1 (5%) and 3 (15%) isolates were resistant to INH and ethambutol (EMB), respectively, of which 1 was resistant to INH and EMB. CONCLUSION: The transmission rate of TB in HIV patients was relatively high; however, the prevalence of drug-resistant strains and TB infection in females was insignificant in this study (p < 0.05); none of the isolates was MDR strains.

Predictors of the prolonged recovery period in COVID-19 patients: a cross-sectional study.

BACKGROUND: The clinical course of COVID-19 may vary significantly. The presence of comorbidities prolongs the recovery time. The recovery in patients with mild-to-moderate symptoms might take 10 days, while in those with a critical illness or immunocompromised status could take 15 days. Considering the lack of data about predictors that could affect the recovery time, we conducted this study to identify them. METHODS: This cross-sectional study was implemented in the COVID-19 clinic of a teaching and referral university hospital in Tehran. Patients with the highly suggestive symptoms who had computed tomography (CT) imaging results with typical findings of COVID-19 or positive results of reverse transcriptase-polymerase chain reaction (RT-PCR) were enrolled in the study. Inpatient and outpatient COVID-19 participants were followed up by regular visits or phone calls, and the recovery period was recorded. RESULTS: A total of 478 patients were enrolled. The mean age of patients was 54.11 ± 5.65 years, and 44.2% were female. The median time to recovery was 13.5 days (IQR: 9). Although in the bivariate analysis, multiple factors, including hypertension, fever, diabetes mellitus, gender, and admission location, significantly contributed to prolonging the recovery period, in multivariate analysis, only dyspnea had a significant association with this variable (p = 0.02, the adjusted OR of 2.05; 95% CI 1.12-3.75). CONCLUSION: This study supports that dyspnea is a predictor of recovery time. It seems like optimal management of the comorbidities plays the most crucial role in recovery from COVID-19.

Prevalence of hepatitis A virus infection in a HIV positive community.

Hepatitis A is acute and usually self-limiting disease, but sometimes it can be dangerous such as in immunosuppressed patients. Purpose of this study is to investigate the prevalence of hepatitis A serology in HIV/AIDS Patients. 247 HIV positive patients from March 2005 to September 2006 were entered in this study. Participants completed questionnaires to elicit demographic, drug and sex risk information, and were (tested for hepatitis A. They were all referred to Counseling center for behavioral diseases in Imam Khomeini Hospital. Cases were chosen from volunteers with no history of jaundice or acute hepatitis. Data were analyzed by SPSS version 13 and results were compared between seropositive and seronegative groups using T test and chi square. Statistical significance was accepted at a level of P < 0.05.200 (80.98%) were male and 47 (19.02) were female. The mean age was 36 +/- 9.3. 238 (96.3%) of patients were seropositive. One hundred percent and 96% who were born in rural and urban areas were seropositive, respectively. Also, 85.7% and 96.6% who reside in rural and urban areas were seropositive, respectively. Iran is an endemic country for hepatitis A in which most people has asymptomatic infectious during childhood. According to high prevalence of hepatitis A positive serology in HIV/AIDS patients, routine vaccination seems to be unnecessary. But special sub populations like HIV infected infants should be evaluated more precisely and different approaches may be needed for them.

Prevalence of COVID-19-like Symptoms among People Living with HIV, and Using Antiretroviral Therapy for Prevention and Treatment.

BACKGROUND: COVID-19 has spread globally with remarkable speed, and currently, there is limited data available exploring any aspect of the intersection between HIV and SARSCoV- 2 co-infection. OBJECTIVE: To estimate the prevalence of clinical symptoms associated with COVID-19 among people living with HIV (PLWH) in Tehran, Iran. DESIGN: Cross-sectional study. METHODS: A total of 200 PLWH were recruited through the positive club via sampling, and completed the symptom-based questionnaire for COVID-19, which was delivered by trained peers. RESULTS: Of 200 participants, respiratory symptoms, including cough, sputum, and shortness of breath, were the most prevalent among participants, but only one person developed symptoms collectively suggested COVID-19 and sought treatments. CONCLUSION: It appears that existing infection with HIV or receiving antiretroviral treatment (ART) might reduce the susceptibility to the infection with SARS-CoV-2 or decrease the severity of the infection acquired. Further research is needed to understand causal mechanisms.

The Relationship Between HIV Antibody Titer, HIV Viral Load, HIV p24 Antigen, and CD4 T-cell Count Among Iranian HIV-positive Patients.

OBJECTIVE: This study aimed to simultaneously measure and assess the correlation between the available HIV infection parameters including HIV antibody, p24 Antigen, CD4 cell count, and viral load at the different stages of HIV disease among HIV-positive individuals in Iran. MATERIALS AND METHODS: Fifty HIV-positive individuals were classified into three stages (1, 2, and 3) according to the HIV disease stages classification, available in Control of Disease and Prevention (CDC) guideline. 10 ml of the venous blood sample was collected to run the tests for HIV antibody and p24 Ag levels, CD4 cell counts, and viral load. Pearson's correlation test was employed to calculate the coefficients for the in-between correlation of different HIV parameters in each stage. RESULTS: Of 50 participants, 17 (34%), 25 (50%), and 8 (16%) patients belonged to stages 1, 2, and 3, respectively. Sexual relationship was the main route of HIV transmission among the patients (36%); however, injecting drug use (20%) was also reported frequently. There was no significant correlation between the parameters of HIV disease in different stages in the present study. CONCLUSION: The findings showed no correlation between HIV parameters in the present study. Considering the fact that the association of HIV antibodies with HIV disease progression in infected individuals is independent of HIV-1 RNA levels, combined measurement of HIV-1 RNA and CD4 cell counts should be routinely carried out in HIV infected patients follow up.

The effect of selenium and zinc on CD4(+) count and opportunistic infections in HIV/AIDS patients: a randomized double blind trial.

Objectives: We assessed the effect of selenium and zinc supplementation on CD4 cell count and the risk of developing opportunistic infections.Methods: In a double blind clinical trial, 146 HIV(+) patients receiving combination antiretroviral therapy with CD4(+) >200/cubic millimeter were screened for comorbidities and opportunistic infections, and randomized to receive daily selenium (200 µg), zinc (50 mg) or placebo for 6 months, before a 3-month follow-up period. CD4 cell counts were measured in the 3th, 6th and 9th months. The serum selenium and zinc were measured in the 6th month. The incidence of opportunistic infection was assessed monthly for 6 months and at the end of the 9th month.Results: The final incidence of supplement deficiency for placebo, zinc and selenium were 46.7%, 44.7% and 50.0%, respectively. Overall compliance with supplementation was 99.42%. Although the changes from baseline were not statistically significant, zinc supplementation was significantly associated with reduced risk of opportunistic infections.Conclusion: Development of the opportunistic infections after zinc supplementation significantly decreased; however, significant improvement in CD4 count was not observed in this group.

CT-scan findings of COVID-19 pneumonia based on the time elapsed from the beginning of symptoms to the CT imaging evaluation: a descriptive study in Iran.

Background. Coronavirus disease 2019 (COVID-19) was initially detected in Wuhan city, China. Chest CT features of COVID-19 pneumonia have been investigated mostly in China, and there is very little information available on the radiological findings occurring in other populations. In this study, we aimed to describe the characteristics of chest CT findings in confirmed cases of COVID-19 pneumonia in an Iranian population, based on a time classification.Methods. Eighty-nine patients with COVID-19 pneumonia, confirmed by a real-time RT-PCR test, who were admitted to non-ICU wards and underwent a chest CT scan were retrospectively enrolled. Descriptive evaluation of radiologic findings was performed using a classification based on the time interval between the initiation of the symptoms and chest CT-scan.Results. The median age of patients was 58.0 years, and the median time interval from the onset of symptoms to CT scan evaluation was 7 days. Most patients had bilateral (94.4%) and multifocal (91.0%) lung involvement with peripheral distribution (60.7%). Also, most patients showed involvement of all five lobes (77.5%). Ground-glass opacities (GGO) (84.3%) and mixed GGO with consolidation (80.9%) were the most common identified patterns. We also found that as the time interval between symptoms and CT scan evaluation increased, the predominant pattern changed from GGO to mixed pattern and then to elongated-containing and band-like-opacities-containing pattern; on the other hand, the percentage of lung involvement increased.Conclusions. Bilateral multifocal GGO, and mixed GGO with consolidation were the most common patterns of COVID-19 pneumonia in our study. However, these patterns might change according to the time interval from symptoms.

Drug resistance patterns in HIV patients with virologic failure in Iran.

We reviewed the medical charts of 1,700 patients diagnosed with HIV who referred to a central HIV clinic in Tehran between 2004 and 2017. Participants who had a viral load of > 200 copies/mL after six months or more on antiretroviral therapy (ART) were grouped as virologic failure (VF). We assessed the demographic characteristics, diagnosis date, first ART regimen, and resistance to various ART drugs. Out of 1,700 patients, 72 (4.2%) had a treatment failure. Among those with treatment failure, 51.3% were on zidovudine + lamivudine + efavirenz, 13.9% were on tenofovir + lamivudine + lopinavir/ritonavir, and 12.5% were on tenofovir + emtricitabine + efavirenz. In patients with treatment failure, the highest resistance was to nucleoside reverse transcriptase inhibitors (NRTIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs) combination (44.4%). In these patients, resistance to tenofovir (one of the NRTIs) was 29.1%. The highest treatment failure was observed among patients treated with nevirapine (NVP) and efavirenz (EFV)-based regimen. Our findings suggest that protease inhibitors should be considered as first-line drugs in ART regimens in VF patients in Iran.

Prevalence and Associated Risk Factors of Hyperglycemia and Diabetes Mellitus Among HIV Positive Patients in Tehran, Iran.

BACKGROUND: The introduction of Antiretroviral Therapy (ART) has resulted in the emergence of some metabolic complications including hyperglycemia and diabetes mellitus among HIV positive patients. The aim of this study was to investigate the prevalence of hyperglycemia, diabetes mellitus and their associated risk factors in HIV positive patients. METHODS: This cross-sectional study was conducted on HIV positive patients who visited Voluntary Counseling and Testing (VCT) center of Imam Khomeini Hospital, Tehran, Iran (2004-2013). Medical records of patients were reviewed retrospectively. A logistic regression model was applied for analysis of the association between glycemic status and relevant risk factors. RESULTS: Out of 480 patients who were included in this study, 267 (55.6%) had hyperglycemia, including 28 (5.8%) with diabetes mellitus and 239 (49.8%) with pre-diabetes. The higher frequency of hyperglycemia, was found to be significantly associated with older age (OR for patients ˃40 years old, 2.260; 95% CI, 1.491, 3.247), male gender (OR, 1.555; 95% CI, 1.047, 2.311), higher Body Mass Index (OR for patients with BMI˃25 Kg/m², 1.706; 95% CI, 1.149, 2.531) and prolonged duration of HIV infection (OR for patients with duration of HIV infection ≥60 months, 2.027; 95% CI, 1.372, 2.992). CONCLUSION: Hyperglycemia, especially pre-diabetes, is highly frequent among Iranian people living with HIV. Male gender, older age, prolonged duration of HIV infection, and higher BMI were associated with a higher prevalence of hyperglycemia. Hence, it is important to screen all HIV infected patients at the time of diagnosis and then periodically for hyperglycemia.

Stigma and Dissatisfaction of Health Care Personnel in HIV Response in Iran: A Qualitative Study.

BACKGROUND AND AIMS: With regard to the disease pandemics of HIV/AIDS, it is clear that there is need for prevention, treatment, care, and support of HIV positive patients in the health care system. In order to achieve these goals, job satisfaction should be a priority for health care staff. This study examined the problems of health care personnel and the behavior of patients undergoing HIV/AIDS counseling at Imam Khomeini Hospital in Tehran, Iran. METHODS: Interviews were conducted individually with 5 health care personnel who participated in this study. Participants had 30 to 45 minutes each per session at the clinic, during which they were able to discuss the problems they faced in their careers. All conversations were officially recorded. RESULTS: The most common problems mentioned by these health care workers included the lack of safety and standardization of work conditions, the lack of appropriate equipment, limited space, high numbers of patients, low staffing levels and financial and morale problems compounded by the lack of support by hospital authorities. CONCLUSION: The authorities need to allocate more funds to provide facilities and appropriate working conditions for health care staff in order to increase job satisfaction and enable staff to provide the best services and care to HIV positive patients.

Zika Virus Infection, Basic and Clinical Aspects: A Review Article.

BACKGROUND: Zika virus infection has recently attracted the attention of medical community. While clinical manifestations of the infection in adult cases are not severe and disease is not associated with high mortality rates, Zika virus infection can have an impact on fetal development and lead to severe neurodevelopmental abnormalities. METHODS: To gain insight into different aspects of Zika virus infection, a comprehensive literature review was performed. With regard to epidemiology and geographical distribution of Zika virus infection, relevant information was extracted from CDC and WHO websites. RESULTS: In this review, we discuss different basic and clinical aspects of Zika virus infection including virology, epidemiology and pathogenesis of disease. Laboratory methods required for the diagnosis of disease together with ethical issues associated with Zika virus infection will also be discussed in detail. CONCLUSION: Herein, we have tried to provide a multi-faceted view of Zika virus infection, with greater emphasis on disease status in Eastern Mediterranean Region.

The Effect of Psycho-Social Problems on Risky Behaviors in People Living With HIV in Tehran, Iran.

Objective: Over the past years, the prevalence and the progression rate of HIV infection in Iran especially through high-risk sexual relationships have regrettably been reported at very high levels. This cross-sectional study tries to analyze stigma, mental health, and coping skills on risky behaviors in HIV-positive adults in Tehran- Iran. Materials and methods: This cross-sectional study was conducted on a sample of 450 HIV-positive adults. Participants completed a socio-demographic questionnaire, the General HealthQuestionnaire-28, the Berger HIV Stigma Scale as well as the Lazarus Ways of Coping Questionnaire (WOCQ). To analyze the data, the independent-samples t-test and Pearson Correlation were used. Results: The findings of this study revealed that mental health, stigma, and avoidance-escape coping mechanisms were correlated with risky behaviors (p ˂ 0.05).Furthermore, the amount of stigma among female individuals compared to men was reported at higher levels and mental health status in the given group was lower than among male individuals. Conclusion: It seems that psychological treatment techniques could be effective in improving mental health and reducing risky behaviors.

Insights from a survey of sexual behavior among a group of at-risk women in Tehran, Iran, 2006.

Despite high rates of HIV among male injection drug users, the sexual behaviors of at-risk women in Iran remain unknown. A questionnaire on HIV knowledge and risk behavior was administered in a Tehran nongovernmental organization targeting runaways and other women seeking safe haven. Half (total N = 50) were less than 24 years old; baseline HIV knowledge was high. The few who acknowledged using illicit substances said they used "frequently." Nonresponse rates to questions regarding sexual behavior were high (12 of 50). Half admitted a history of sexual activity; 40% of those reported their first sexual contact with someone other than their husband; three people had multiple partners. Three women reported a history of rape. Zero (97.5% one-sided confidence interval [CI] = 0, 0.17) of 35 women tested positive for HIV or syphilis. This study documents the existence of sexual behavior in a population of Iranian women, represents one of the first attempts at sexual research in the Iranian context, and highlights challenges in surveying this vulnerable group.
