This study aimed to measure internal and external HIV stigma and their associated factors among people living with HIV in the southeast of Iran. Using convenience sampling and a standard questionnaire, we recruited 104 HIV-positive patients (40% women) in 2018-2019 from two public clinics in Kerman, Iran. The internal stigma scale ranged from 0-22 and the external stigma scale ranged from 0-11 in which a higher score indicates higher stigma. The mean internal stigma score was 10.7 (SD: 5.2), and that of the external stigma score was 3.1 (SD: 2.9). In multivariable regression analysis, women (Adjusted (Adj). ᵦ=-3.3; p=0.08), and married people (Adj. ᵦ=-5.5; p=<0.001) experienced less internal stigma. In contrast, those who were a member of support group of PLHIV (Adj. ᵦ=2.8; p=0.04), and those infected by sexual contact (Adj. ᵦ=2.1; P=0.006) experienced a higher internal stigma. Moreover, married people (Adj. ᵦ=-1.4; p=0.01), those with high school or higher education (Adj. ᵦ=-1.7; p=0.002), and those with other transmission routes (Adj. ᵦ=-1.4; P=0.01) experienced lower external stigma. People living with HIV feel considerable internal and external stigma. Addressing HIV stigma should be tailored based on gender, education, marriage, peer groups, and risk groups as these factors have different effects on stigma experiences.

Bhutan has a low-level HIV epidemic, with sporadic cases across the whole population. Our society is witnessing momentous social and cultural changes coinciding with the arc of the HIV pandemic. Therefore, this paper systematically assesses socio cultural determinants of HIV in Bhutan for appropriate responses to end the AIDS epidemic by 2030.

We reviewed the literature relevant to HIV in Bhutan using appropriate search engines. We adapted Dahlgren and Whitehead’s model of social health determinants in the population as a conceptual framework.

Young age played the salient role between rapid sociocultural changes and HIV in Bhutan. Most teens are sexually active, has relaxed sexual norms, low condom use, and has multiple sexual partners. Gender identity and sexual orientation are increasingly fluid among transgender and gay/bisexual men. Worksites with migrants and entertainment venues are nexuses for sexual networking resulting in transactional/sex work.

Our findings suggest ahigh potential for a shift from diffuse cases of HIV to more concentrated HIV epidemic. HIV responses need to be tailored specifically for key populations instead of the current generalized approach. We recommend community-based HIV Self Testing and social support to overcome the structural barriers to enhance case diagnosis

To apply a novel method to adjust for HIV knowledge as an unmeasured confounder for the effect of unsafe injection on future HIV testing.

The data were collected from 601 HIV-negative persons who inject drugs (PWID) from a cohort in San Francisco. The panel-data generalized estimating equations (GEE) technique was used to estimate the adjusted risk ratio (RR) for the effect of unsafe injection on not being tested (NBT) for HIV. Expert opinion quantified the bias parameters to adjust for insufficient knowledge about HIV transmission as an unmeasured confounder using Bayesian bias analysis.

Expert opinion estimated that 2.5%–40.0% of PWID with unsafe injection had insufficient HIV knowledge; whereas 1.0%–20.0% who practiced safe injection had insufficient knowledge. Experts also estimated the RR for the association between insufficient knowledge and NBT for HIV as 1.1-5.0. The RR estimate for the association between unsafe injection and NBT for HIV, adjusted for measured confounders, was 0.96 (95% confidence interval: 0.89,1.03). However, the RR estimate decreased to 0.82 (95% credible interval: 0.64, 0.99) after adjusting for insufficient knowledge as an unmeasured confounder.

Our Bayesian approach that uses expert opinion to adjust for unmeasured confounders revealed that PWID who practice unsafe injection are more likely to be tested for HIV – an association that was not seen by conventional analysis.

Mass screening for the coronavirus disease 2019 (COVID-19) began in Iran on March 23, 2020, with the purpose of improving early detection of patients for their own health and to prevent onward transmission to others. In this study, we evaluated the impact of the change towards mass screening on new cases reported, cases recovered, and deaths due to COVID-19.

This study analyzed the daily reports on the number of new cases confirmed by polymerase chain reaction (PCR) testing, cases recovered, and deaths due to COVID-19 provided to the Ministry of Health and Medical Education of Iran. Changes in trends on these outcomes were evaluated using interrupted time series analysis.

From February 19 to May 6, 2020, a total of 519544 COVID-19 tests were done and 101650 diagnoses were made (case/ test ratio 19.6%). For the same period, 6418 deaths due to COVID-19 were reported (case fatality ratio 6.3%). The number of cases detected increased significantly over the period of scale-up of mass screening (P=0.003), as did the number of recovered cases (P=0.001). The number of deaths due to COVID-19 did not change before versus after mass screening.

Following the scale-up of mass screening for COVID-19 in Iran, the rate of new cases detected and reported recovered accelerated significantly. Mass screening is likely to have detected many mild and asymptomatic cases that were infectious. Our data support the role that mass screening, coupled with isolation and contract tracing, can have in slowing the COVID-19 epidemic

Antiretroviral (ARV) therapy extends life for persons living with HIV. Antiretroviral treatment (ART) has been rapidly expanding coverage around the world, including in Iran. However, ART drug resistance also rapidly develops with expanding use and limits effectiveness and treatment options. The aim of this study was to monitor the appearance of new mutations conferring HIV pretreatment drug resistance in the treatment of naïve patients with HIV in Iran. Blood samples were obtained from ARV treatment‑naïve patients from 8 different provinces in Iran in 2016 for genotyping for drug resistance mutations. Sequences were successfully obtained from 90 specimens. Of these, 2 (2%) mutations conferring resistance to protease inhibitors, 2 (3%) conferring resistance to nucleoside reverse transcriptase inhibitors (NRTIs), and 9 (13%) conferring resistance to non‑NRTI (NNRTI) were detected. Any ARV‑resistant drug mutation was found in 11 patients (12%). Nearly one in 8 ARV‑naïve patients had mutations associated with NNRTI resistance in diverse areas of Iran in 2016. Iranian ARV therapy guideline for HIV could consider non‑NNRTI‑based first‑line therapies and expand routine drug resistance testing before treatment initiation as according to HIV drug resistance recommendations of the World Health Organization.

Throughout the world, many migrant and mobile populations are at elevated risk for HIV. Iran has a large immigrant population from neighboring Afghanistan; however, few data exist on the prevalence of HIV in this community. In 2008, we conducted a study to assess the presence of HIV infection among 477 immigrants in a town to the northeast of Tehran using a rapid test in the field. HIV prevalence was 0.2% (95% CI 0.005-1.2) with one person HIV-positive. We recommend periodic HIV sero-surveillance with detailed behavioral measures for this population in the future.

We report a rare case of brucellosis presenting with pleural and pericardial effusions in a 35 year-old male rancher in Iran with fever and dyspnea. Such findings should prompt inclusion of brucellosis in the differential diagnosis in endemic areas.

Prostate cancer is a major cause of morbidity and mortality in Iran, yet there are few studies examining risk factors specific to the Iranian context. We conducted a case-control study to explore risk factors for prostate cancer in Mazandaran, Iran from 2005 to 2008. The cases were 137 men with clinicopathologically confirmed prostate cancer. Controls were 137 neighborhood and age match men without prostate cancer by PSA and digit examination. Analysis comprised an exploratory stage to identify potential risk factors, defined as variables associated with case status at the P < 0.20 level in conditional logistic regression. A second stage included all potential risk factors in multiple conditional logistic regression analysis, retaining those associated with prostate cancer at the P < 0.05 level. Potential risk factors for prostate cancer in exploratory analysis included family history of prostate cancer, history of other cancer, prostatitis, alcohol consumption, pipe or hookah smoking, walking to work, duration of occupational physical activity, intensity of occupational physical activity, body mass index, and older age. Multivariate analysis found intensity of occupational physical activity, prostatitis, and older age as independent predictors of increased risk for prostate cancer in this Iranian population. Our study confirms several recognized risk factors for prostate cancer, contributes evidence to the discussions of other hypothesized risk factors, and points to potentially new factors. Findings, along with confirmatory studies, can help guide efforts for early detection, treatment, and prevention for this common malignancy that is set to increase in Iran in future decades.

We measured the prevalence of HBV surface antigen (HBsAg) among male injection drug users (IDUs) in Detention, Tehran, Iran. A cross-sectional survey included 499 male IDUs arrested by police during a predetermined police sweep in Tehran (February, 2006). A questionnaire was filled out for each individual. Blood specimens were collected for HBsAg testing. Prevalence of HBsAg was 5.8% (95% CI 3.6-7.9). The majority of chronic HBV infections, 69.2%, were among adults age 25 to 34 years. The high prevalence of HBsAg highlights the need for special efforts to increase vaccination among adult populations at risk for HBV infection in order to reducing continuing transmission and stave off future high burden of disease.
