Updates on the Epidemiology of the Human T-Cell Leukemia Virus Type 1 Infection in the Countries of the Eastern Mediterranean Regional Office of the World Health Organization with Special Emphasis on the Situation in Iran. Viruses 2022; 14:v14040664. [PMID: 35458394 PMCID: PMC9029775 DOI: 10.3390/v14040664] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 03/12/2022] [Accepted: 03/21/2022] [Indexed: 02/04/2023] Open
Abstract
Background: The epidemiology and prevalence of the Human T-cell leukemia virus type-1 (HTLV-1) infection represent a recommended priority by global health agencies. An in-depth revision to update the status of this infection in countries including those of the Eastern Mediterranean Regional Office (EMRO) of the World Health Organization is hence required. Methods: Ninety-seven studies evaluating the HTLV-1 infection in low- and high-risk populations in EMRO countries were retrieved from the international electronic databases and were used to assess the epidemiological status of the infection in these countries. Results: Most epidemiologic reports were published from Iran, with more than 50% of Iranian prisoners and around 4% of healthy individuals reported to have the infection. In Egypt, a considerable prevalence of the virus spans around 1.11% of blood donors. Foci of HTLV-1 infection are also present in some countries and require a careful epidemiological evaluation. In the other EMRO countries, a lower prevalence that does not exceed 1% was reported. Conclusion: The epidemiology and prevalence of HTLV-1 in the EMRO countries require a tight revision and update. Published studies reveal a scarce distribution of the virus in the African countries of EMRO, while a lower prevalence is denoted in the Asian countries of EMRO, except in Iran, where the prevalence is high.

Abstract
Purpose: The number of bone allograft transplantations required in low- and middle-income countries (LMICs) is growing very quickly. No previous study has investigated the challenges clinical banks face to sustain operations or meet this demand. The purpose of this study was to conduct a systematic review of the barriers to implementation and sustainability of clinical bone tissue banks in LMICs. Barriers identified in clinical bone banking can shed light on strategies for overcoming obstacles in other biobanking programs. Methods: A systematic review protocol was registered with PROSPERO under identification number CRD42019136045. LMIC was defined using World Bank criteria. A search strategy targeting PubMed, Cumulative Index of Nursing and Allied Health Literature (CINAHL), and the World Health Organization (WHO) Global Health Library was used. Studies from the inception of bone banking until June 4, 2019, that discussed an identifiable barrier to bone banking were included. Study quality was assessed using The Critical Appraisals Skills Programme (CASP) Qualitative Checklist. Results: Of studies identified, 33 studies were included in the final analysis. Based on the full-text review, the primary barriers identified were lack of regulation, low donor rates, and insufficient training and staffing. CASP analysis performed on the 24 qualitative articles showed an average of 3.6 qualitative measurements met. Conclusions: As international organizations such as the International Atomic Energy Agency (IAEA) restructure their participation in global bone banking regulation, these barriers such as lack of regulation, low donor rates, and insufficient training and staffing could pose a challenge to meeting the rising demand for bone transplantation in LMICs. Articles with higher quality evidence are needed to better define barriers and propose evidence-based solutions.

Abstract
Aim: This study aimed to investigate the frequency and phylogenetic distribution of human T-lymphotropic virus type 1 (HTLV-1) in thalassemia cases. Methods: Between 2006 and 2013, a total of 100 thalassemic individuals were investigated for HTLV-1 infections. Results: Four people (4%) were reactive for HTLV antibodies. No considerable correlation was seen between factors such as age, blood transfusion history, surgery, marital status, gender and blood types. All HTLV-1 sequences belonged to the transcontinental (A) subgroup in the cosmopolitan (a) subtype. Conclusion: In addition to phylogenetic distribution, our results demonstrate that the prevalence of HTLV-1 infection among thalassemia patients in Mashhad is higher than that of previous studies.

Abstract
BACKGROUND Prisoners are at high risk of blood borne and sexually transmitted infections due to their high involvement in risky behaviors. In this descriptive/cross-sectional study, the prevalence, sero-prevalence, and risk factors for bloodborne tumor viruses including HTLV-I, HBV, HCV, and KSHV were evaluated among inmates of two central prisons in the northeast of Iran. METHODS Blood samples of 1114 inmates were analyzed for the presence of anti HTLV-I, KSHV, and HCV antibodies and HBsAg by ELISA. PCR tests were performed to confirm the presence of these viruses in plasma and identify the current infections. RESULTS The sero-prevalence of HCV, HBV, HTLV-I, and KSHV was 24.5%, 4.2%, 3.4%, and 3.2% and the prevalence of HCV, HBV, HTLV-I, and KSHV was 19.1%, 2.1%, 2%, and 3%, respectively. HCV infection was significantly associated with history of imprisonment, tobacco consumption, alcohol consumption, intravenous drug use, length of imprisonment, and type of crime committed. Thirty one (2.8%) prisoners had HCV-KSHV co-infection, 16 (1.5%) had HCV-HTLV-I co-infection, and 14 (1.3%) had HBV-HCV co-infection. Triple co-infection was observed in seven cases and one case had four infections concomitantly. CONCLUSIONS This epidemiological study indicated different rates and transmission risks for these viruses. HCV was the most contagious viral infection and HTLV-I was the weakest in the prisoners. Apart from KSHV infection which its prevalence was as twice as in the general population, the prevalence of HBV and HTLV-I in prisoners was nearly in ranges of the general population.

Abstract
Human T-cell leukemia virus (HTLV) indeterminate Western blot (WB) serological patterns are frequently observed in plasma/serum from persons living in intertropical areas. In the framework of ongoing projects on HTLV-1/2 and related viruses in Central Africa, we systematically analyzed plasma from villagers living in South Cameroon by WB. The group included 1,968 individuals (mean age, 44 years; age range, 5 to 90 years; 978 women/990 men), both Bantus (1,165) and Pygmies (803). Plasma samples were tested by WB analysis (MPD HTLV Blot 2.4) and interpreted according to the manufacturer's instructions. Only clear bands were considered in the analysis. Among the 1,968 plasma samples, 38 (1.93%) were HTLV-1, 13 (0.66%) were HTLV-2, and 6 (0.3%) were HTLV WB seropositive. Furthermore, 1,292 (65.65%) samples were WB sero-indeterminate, including 104 (5.28%) with an HTLV-1 Gag-indeterminate pattern (HGIP) and 68 (3.45%) with a peculiar yet unreported pattern exhibiting mostly a strong shifted GD21 and a p28. The other 619 (31.45%) samples were either WB negative or exhibited other patterns, mostly with unique p19 or p24 bands. DNA, extracted from peripheral blood buffy coat, was subjected to PCR using several primer pairs known to detect HTLV-1/2/3/4. Most DNAs from HTLV-1- and HTLV-seropositive individuals were PCR positive. In contrast, all the others, from persons with HTLV-2, HGIP, new WB, and other indeterminate patterns, were PCR negative. Epidemiological determinant analysis of the persons with this new peculiar WB pattern revealed that seroprevalence was independent from age, sex, or ethnicity, thus resembling the indeterminate profile HGIP rather than HTLV-1. Moreover, this new pattern persists over time.

Abstract
Bovine leukemia virus (BLV) is a retrovirus closely related to the human T-lymphotropic virus type 1 (HTLV-1). BLV is a major animal health problem worldwide causing important economic losses. A series of attempts were developed to reduce prevalence, chiefly by eradication of infected cattle, segregation of BLV-free animals and vaccination. Although having been instrumental in regions such as the EU, these strategies were unsuccessful elsewhere mainly due to economic costs, management restrictions and lack of an efficient vaccine. This review, which summarizes the different attempts previously developed to decrease seroprevalence of BLV, may be informative for management of HTLV-1 infection. We also propose a new approach based on competitive infection with virus deletants aiming at reducing proviral loads.
