The increasing trend of blood donation in Iran

BACKGROUND: This is the first study on the blood donation trend in Iran at a national level. We report different characteristics of blood donation such as demographic status, donor type, donation trend, and geographical distribution of blood donation in Iran between 2003 and 2017.METHODS: This study used data registered in the donor vigilance part of the Iranian Blood Transfusion Organization. Statistical analysis was conducted using SPSS (SPSS Inc., Chicago, IL, USA) and ArcMap GIS version 10.2 software. A P-value <0.05 was considered statistically significant.RESULTS: Based on the study results, blood donation in Iran reached >2 million units in 2017; moreover, it is predicted that Iran will achieve >29 donations per 1,000 population in 2022. The proportion of regular and repeated donors increased from 77% in 2013 to 87% in 2017. The average blood donation rate in seven provinces was higher than the national average, and the average growth rate of their blood donation per population was positive.CONCLUSION: The results of the current study showed that there is a recent increasing trend toward blood donation in Iran. Furthermore, the largest share of donations is related to regular donors. The increasing proportion of regular and repeated donors has led to the improvement in the quality and consequently health level of donated blood.

Modeling of human immunodeficiency virus modes of transmission in Iran

Main technique to control acquired immunodeficiency syndrome [HIV] infection is the effective preventive programs among high-risk groups. Modeling is one of the effective methods where there is inadequate data. We used the modes of transmission [MOT] model to predict the transmission of HIV infection in Iran. We systematically searched published and grey literature to find values for the input parameters of MOT in 2010. The data were discussed by experts before being fed into the model. Using the Monte Carlo simulation, we computed the 95% confidence interval [CI] for the outputs of the MOT. The MOT estimates that 9136 new HIV infections would have occurred in Iran in 2010 [95% CI: 6831, 11757]. About 56% [95% CI: 47.7%, 61.6%] of new infections were among intravenous drug users [IDUs] and 12% [95% CI: 9.5%, 15%] among their sexual partners. The major routes of direct and indirect HIV transmission in Iran are unsafe injection [68%] and unprotected sexual contact [34% unprotected heterosexual and 10% homosexual] respectively. If current coverage for safe injection among IDUs increases from 80% to 95%, new HIV infections in this group would decrease around 75%. IDUs remain at highest risk of HIV infection in Iran, so the preventive program coverage for IDUs and their spouses needs to be increased. As the sexual transmission of HIV contributes increasingly to the pool of new infections, serious measures such as harm reduction program are required to reduce sexual transmission of HIV among the relevant key populations.

Assessing the prevalence of HIV among Afghan immigrants in Iran through rapid HIV testing in the field

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
