The noticeable spike in the prevalence of co-infection with human immunodeficiency virus (HIV) and Treponema pallidum (syphilis) has generated renewed interest in the subject. While it has been well-established that HIV infection does exert some effect on the natural history of syphilis, it was not until the recent resurgence in the contraction of syphilis by HIV patients that researchers were able to document the impact that this disease has on the course of the HIV infection. A correct assertion is that there exists a complex interaction between HIV and syphilis and that this interaction remains partly understood. New data, though, have emerged that augment our comprehension of the interaction between syphilis and HIV infection as it applies to the heterosexual population, bi-sexual partners, and men who have sex with men (MSM).
人类免疫缺陷病毒(HIV)和梅毒螺旋体(梅毒)共同感染的流行率显著上升,这引起了人们对这一主题的新兴趣。虽然人们已经确定,艾滋病毒感染确实会对梅毒的自然史产生一些影响,但直到最近艾滋病毒患者的梅毒收缩再次出现,研究人员才能够记录这种疾病对艾滋病毒感染过程的影响。一个正确的断言是,艾滋病毒和梅毒之间存在着复杂的相互作用,这种相互作用仍有部分了解。然而,新的数据已经出现,增强了我们对梅毒和艾滋病毒感染之间相互作用的理解,因为它适用于异性恋人群、双性恋伴侣和男男性行为者。

Acute viral infection belong to the group of anthropode [1,2]. Chikungunya fever now a days is spreading worldwide and some recent studies shown the different t features and most clinical features is topic of inertest is bony pain, which is the most severe form [3-6]. In India the Chikungunya fever is going to be the increasing number in the financially and economical burden [7]. Dengue and Chikungunya are major worldwide wellbeing worries because of their proceeded with spread and strengthening plague exercises all through a large portion of the tropical and subtropical areas of the world. Consistent flare-ups of dengue have been accounted for all through the majority of the tropical and sub-tropical areas of the world for a very long while [8-10] while Chikungunya pandemics have accomplished worldwide dispersion inside the previous ten years; yet extensive scale pestilences of dengue fever and Chikungunya fever has just as of late introduced as a developing wonder in Africa [11]. Tanzania, the same number of other African nations, is encountering a move in illness transmission designs with respect to febrile irresistible maladies. While the quantity of instances of intestinal sickness are diminishing in a few nations of subSaharan Africa [12-15], the quantity of febrile cases because of different causes than jungle fever are still high [16].
急性病毒感染属于类人猿[1,2]。基孔肯雅热目前正在世界范围内传播,最近的一些研究表明其不同的特征和大多数临床特征是骨痛,这是最严重的形式[3-6]。在印度,基孔肯雅热将成为日益增加的财政和经济负担。登革热和基孔肯雅热是世界范围内主要的健康问题,因为它们在世界大部分热带和亚热带地区继续传播和加强鼠疫演习。在很长一段时间内,世界上大多数热带和亚热带地区都发生了登革热的持续突发事件[8-10],而基孔肯雅大流行在过去十年中已经在世界范围内扩散;然而,登革热和基孔肯雅热的大规模流行最近在非洲成为发展中的奇迹。坦桑尼亚和其他数目相同的非洲国家一样,正面临着与发热的不可抗拒的疾病有关的疾病传播设计的变化。虽然在撒哈拉以南非洲的一些国家,肠道疾病的病例数量正在减少[12-15],但与丛林热不同,由不同原因引起的发热病例数量仍然很高。

Although dengue was once a periodic disease that caused long-interval epidemics, today it is considered the most important mosquito-borne viral disease in the world [1]. Per year, approximately fifty to one hundred million cases of dengue fever are recorded worldwide [2]. Half a million of these cases result in the most severe form of dengue fever (DF) known as dengue hemorrhagic fever (DHF) [2]. DHF is a disease that predominantly affects children under 15 years of age and is characterized by the sudden onset of fever, thrombocytopenia, and vascular leak syndrome [3]. DHF occurs due to an infection by the dengue virus, which is part of the Flaviviridae family [4]. The virus is icosahedral, enveloped, single-stranded, positive-sense RNA [5]. The icosahedral core is forty to fifty nanometers in diameter and contains the C protein that encapsulates the viral genome [5]. Two viral proteins, M and E, which compose the lipid envelope, surround the core [5]. The infection is caused by one of the four serotypes of the dengue virus (DENV): DENV-1, DENV-2, DENV3, and DENV-4 [4]. Infection by one of the serotypes does not provide immunity against infection with the other serotypes [4].
虽然登革热曾经是一种周期性疾病,会引起长时间间隔的流行病,但今天它被认为是世界上最重要的蚊媒病毒性疾病。每年,全世界大约有5千万到1亿登革热病例。其中50万例导致最严重形式的登革热(DF),即登革出血热(DHF)[2]。登革出血热是一种主要影响15岁以下儿童的疾病,其特征是突然发热、血小板减少和血管渗漏综合征[3]。登革出血热是由于感染登革病毒而发生的,登革病毒是黄病毒科的一部分。病毒是二十面体,包膜,单链,正义RNA[5]。二十面体核心直径为40至50纳米,含有包裹病毒基因组[5]的C蛋白。两种病毒蛋白,M和E,组成脂质包膜,包围核心[5]。感染是由登革热病毒(DENV)的四种血清型之一引起的:DENV-1、DENV-2、DENV- v3和DENV-4[4]。其中一种血清型感染不能提供对其他血清型感染的免疫力。

Submit Manuscript | http://medcraveonline.com condition as a situation where the host’s genome was invaded, manipulated and exploited by a viral intruder. By the end of 2016, there were 36.9 million HIV-infected individuals living around the world and 19.5 million people were accessing antiretroviral therapy (UNAIDS 2017). We can typically treat patients with antiretroviral therapies and other symptomatic treatments or we can develop new ways to prevent the HIV infection with the development of new vaccines. However, while different vaccines are being tested with various degrees of success, there is still no evidence vaccination will be the best choice due to the HIV infection strategy. Therefore, while scientists keep testing and designing new vaccines against HIV/AIDS, recent advances in personalized medicine can be a game changer. Scientists are evaluating a new CRISPR-Cas9 strategy to achieve a permanent cure for HIV infection. There have been different approaches to treat HIV/ AIDS but there are several reasons preventing scientists from finding a viable cure for the HIV infection, for example, the HIV virus plasticity and its ability to remain in a latent state in hidden HIV reservoirs away from the host immune defense system [1]. A hallmark of the AIDS pathogenesis is the progressive depletion of CD4+ T-cell populations in association with an impaired immunity response [2]. It is that immune response weakening and the inability to initiate an effective cellular immune response against HIV that increases the susceptibility to opportunistic and often deadly infections. An updated list of opportunistic diseases and recommended responses is prepared yearly by the Centers for Disease Control and Prevention, the National Institutes of Health, and the HIV Medicine Association of the Infectious Diseases Society of America [3]. Recent studies identified a new CD4 T-cell HIV reservoir marker that might pave the way for the development of new HIV treatments [4, 5]. CD32a+ lymphocytes can be used to identify the elusive HIV-1 reservoir. That finding may lead to novel insights that will allow the specific targeting and elimination of this resistant HIV reservoir. Establishing CD32a+ as a marker to identify those quiescent HIV cells is the perfect target to unleash the most recent genetic engineering tool that allows the modification of the hosts’ genome, the CRISPR-Cas9 method. The CRISPR-Cas9 gene editing complex is an elegant tool from the Streptococcus pyogenes [6]. The Cas9 nuclease protein uses a guide RNA sequence to cut DNA at a complementary site making this process the ideal mechanism to direct a precise genetic deletion and modification of the genome.
提交手稿|http://medcraveonline.com宿主基因组被病毒入侵者入侵、操纵和利用的情况。截至2016年底,世界各地有3690万艾滋病毒感染者,1950万人正在接受抗逆转录病毒治疗(联合国艾滋病规划署,2017年)。我们通常可以用抗逆转录病毒疗法和其他症状治疗来治疗患者,或者我们可以通过开发新疫苗来开发预防艾滋病毒感染的新方法。然而,尽管不同的疫苗正在测试中,并取得了不同程度的成功,但由于艾滋病毒感染策略,仍然没有证据表明接种疫苗将是最佳选择。因此,当科学家们不断测试和设计新的艾滋病毒/艾滋病疫苗时,个性化医学的最新进展可能会改变游戏规则。科学家们正在评估一种新的CRISPR-Cas9策略,以实现HIV感染的永久治愈。治疗HIV/AIDS有不同的方法,但有几个原因阻碍了科学家找到治疗HIV感染的可行方法,例如,HIV病毒的可塑性及其在远离宿主免疫防御系统的隐藏HIV库中保持潜伏状态的能力[1]。艾滋病发病机制的一个标志是CD4+T细胞群的逐渐耗竭与免疫反应受损有关[2]。正是这种免疫反应减弱,无法启动针对艾滋病毒的有效细胞免疫反应,增加了对机会性感染的易感性,而且往往是致命的感染。美国疾病控制与预防中心、美国国立卫生研究院和美国传染病学会HIV医学协会每年都会编制一份最新的机会性疾病和建议应对措施清单[3]。最近的研究发现了一种新的CD4 T细胞HIV库标志物,可能为开发新的HIV治疗方法铺平道路[4,5]。CD32a+淋巴细胞可用于鉴定难以捉摸的HIV-1库。这一发现可能会带来新的见解,从而能够特异性地靶向和消除这种具有耐药性的艾滋病毒库。建立CD32a+作为识别那些静止的HIV细胞的标记物,是释放最新的基因工程工具CRISPR-Cas9方法的完美靶点,该工具可以修饰宿主的基因组。CRISPR-Cas9基因编辑复合体是化脓性链球菌的一种优雅工具[6]。Cas9核酸酶蛋白使用引导RNA序列在互补位点切割DNA,使这一过程成为指导基因组精确遗传缺失和修饰的理想机制。

HIV is continuum of progressive damage traversed through survival time. Using data from 204 positive women and men, we carried-out survival analysis using Kaplan– Meier curves, Cox proportional hazard regression and Markov-chain model to map CD4 progression and health-condition outcomes. Progression was better among nondefaulters {adjusted hazard ratio [AHR]-0.11, 95% CI 0.03–0.31 (Log rank p<0.001) (chi2=73.62, p<0.001)}, those with higher self-perceived adherence and early initiation of ART. TB-HIV co-infection translated in lower progression and even lower among women [AHR]-0.08, 95% CI 0.02–0.28; Log rank p<0.001) (chi2=71.72, p<0.001). Similar result was observed in women who reported side effects and who defaulted treatment. Immune reconstitution emerged strongly from Markov-chain model, with striking gender gap. Probability of women maintaining working condition was quite low (0.88) as compared to men (0.94). Transition to better health from bed-ridden state was also lower among women. A health-care delivery gender-responsive.
艾滋病毒是一种连续的渐进式损害,贯穿整个生存时间。使用来自204名阳性女性和男性的数据,我们使用Kaplan - Meier曲线、Cox比例风险回归和马尔可夫链模型进行生存分析,绘制CD4进展和健康状况结果。非违约者(校正风险比[AHR]-0.11, 95% CI 0.03-0.31 (Log rank p<0.001) (chi2=73.62, p<0.001))、自我感觉依从性较高和早期开始抗逆转录病毒治疗的患者进展更好。TB-HIV合并感染在女性中转化为较低的进展,甚至更低[AHR]-0.08, 95% CI 0.02-0.28;Log rank p<0.001) (chi2=71.72, p<0.001)。在报告副作用和未接受治疗的妇女中也观察到类似的结果。免疫重构在马尔可夫链模型中表现强烈,性别差异显著。女性维持工作状态的可能性(0.88)比男性(0.94)低得多。女性从卧床状态向更好的健康状态过渡的比例也较低。促进性别平等的保健服务。
