[PMID: 30717133 PMCID: PMC6406803 DOI: 10.3390/jcm8020163] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2019] [Revised: 01/18/2019] [Accepted: 01/22/2019] [Indexed: 12/17/2022] Open
Abstract
The current trends and spectrum of acquired immunodeficiency syndrome (AIDS)-related opportunistic illnesses (AOIs) among newly diagnosed human immunodeficiency virus (HIV)-infected patients after the implementation of the 2006–2015 national anti-tuberculosis (TB) programmes in Taiwan remain unknown. We retrospectively reviewed 1757 patients at two centres in southern Taiwan between 2001 and 2015. Based on the anti-TB programme, patients were classified into periods 1 (2001–2005), 2 (2006–2010), and 3 (2011–2015). We further analysed factors associated with Mycobacterium tuberculosis (MTB) at presentation and during follow-up. The overall AOI incidence rate (23.6%) remained unchanged across the periods, with 81.4% of AOIs occurring at presentation. Pneumocystis jirovecii pneumonia was the leading AOI across the periods. MTB declined significantly from period 1 to period 3 (39.3% vs. 9.3%). Age and CD4+ cell count <200 cells/µL (vs. ≥501) were the risk factors associated with MTB at presentation, whereas period 2/3 (vs. period 1) was the protective factor. Intravenous drug use (vs. homosexual contact) was the risk factor associated with MTB during follow-up, and period 3 (vs. period 1) was the protective factor. AOI statistics in Taiwan must be closely monitored for fluctuations. Although MTB decreased substantially after implementation of the anti-TB programmes, additional efforts to reduce MTB are required.

Disparities in the Magnitude of Human Immunodeficiency Virus-related Opportunistic Infections Between High and Low/Middle-income Countries: Is Highly Active Antiretroviral Therapy Changing the Trend? Ann Med Health Sci Res 2016; 6:4-18.

Abstract
Opportunistic infections (OIs) cause significant morbidity/mortality in human immunodeficiency virus (HIV)-infected individuals globally. Disparities between high-income countries (HICs) and low/middle-income countries (LMICs) in the magnitude of HIV-related OIs in pre-highly active antiretroviral therapy (HAART) populations was reviewed, and HAART-induced decline in OIs was further compared between the two settings. Studies published in English from onset of HIV epidemic up to December 2013 were searched in PubMed, Google, Google Scholar, and African Journal online. An article was included if (a) the study was conducted in HIC or LMIC, (b) the age of the participants was ≥12 years, (c) the HAART status of the participants was stated, and (d) various types of OIs were investigated. In predominantly pre-HAART populations, the incidence and prevalence of overall HIV-related OIs in HIC ranged from 5.5 to 50.0 per 100 person-years (PY) and 27.4-56.7%, respectively. In LMIC, the respective overall incidence and prevalence of OIs were 12.2-93.9 per 100 PY and 32.0-77.7%. Pneumocystis jirovecii pneumonia, candidiasis, Cytomegalovirus disease, Mycobacterium avium complex disease, and Kaposi's sarcoma were the most frequent OIs in HICs while tuberculosis, candidiasis, chronic diarrhea, and cryptococcosis were predominant in LMICs. The introduction of HAART led to substantial reduction in the incidence of OIs with more impressive percentage decline in HICs (43-97%) compared to 30-79% in LMICs. Disparities in the magnitude of HIV-related OIs between HICs and LMICs are evident both in the pre-HAART and post-HAART era. Efforts to optimize HAART-induced decline in HIV-related OIs should become a global health priority irrespective of prevailing socioeconomic circumstances.

McMahon T, Ward PR. HIV among immigrants living in high-income countries: a realist review of evidence to guide targeted approaches to behavioural HIV prevention. Syst Rev 2012; 1:56. [PMID: 23168134 PMCID: PMC3534573 DOI: 10.1186/2046-4053-1-56] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2012] [Accepted: 10/29/2012] [Indexed: 11/10/2022] Open
Abstract
UNLABELLED BACKGROUND Immigrants from developing and middle-income countries are an emerging priority in HIV prevention in high-income countries. This may be explained in part by accelerating international migration and population mobility. However, it may also be due to the vulnerabilities of immigrants including social exclusion along with socioeconomic, cultural and language barriers to HIV prevention. Contemporary thinking on effective HIV prevention stresses the need for targeted approaches that adapt HIV prevention interventions according to the cultural context and population being addressed. This review of evidence sought to generate insights into targeted approaches in this emerging area of HIV prevention. METHODS We undertook a realist review to answer the research question: 'How are HIV prevention interventions in high-income countries adapted to suit immigrants' needs?' A key goal was to uncover underlying theories or mechanisms operating in behavioural HIV prevention interventions with immigrants, to uncover explanations as how and why they work (or not) for particular groups in particular contexts, and thus to refine the underlying theories. The realist review mapped seven initial mechanisms underlying culturally appropriate HIV prevention with immigrants. Evidence from intervention studies and qualitative studies found in systematic searches was then used to test and refine these seven mechanisms. RESULTS Thirty-four intervention studies and 40 qualitative studies contributed to the analysis and synthesis of evidence. The strongest evidence supported the role of 'consonance' mechanisms, indicating the pivotal need to incorporate cultural values into the intervention content. Moderate evidence was found to support the role of three other mechanisms - 'understanding', 'specificity' and 'embeddedness' - which indicated that using the language of immigrants, usually the 'mother tongue', targeting (in terms of ethnicity) and the use of settings were also critical elements in culturally appropriate HIV prevention. There was mixed evidence for the roles of 'authenticity' and 'framing' mechanisms and only partial evidence to support role of 'endorsement' mechanisms. CONCLUSIONS This realist review contributes to the explanatory framework of behavioural HIV prevention among immigrants living in high-income countries and, in particular, builds a greater understanding of the suite of mechanisms that underpin adaptations of interventions by the cultural context and population being targeted.

Abstract
The immigrant population in Spain, whether legal or not, has been entitled to healthcare under the same conditions as the Spanish population since the year 2000. The entry into vigour of the Royal Decree-Law 12/2012 of 20 April has significantly restricted this right, so that unauthorized or non-resident foreigners may now only receive emergency care, if they are under 18 or pregnant women. Out of an estimated 459,909 illegal immigrants in our country, 2,700 to 4,600 are probably infected with HIV; 1,800 to 3,220 know that they are infected, and 80% of the latter could receive antiretroviral treatment. The Royal Decree-Law is likely to cause many undesirable consequences in this population infected with HIV: increasing mortality, promoting the emergence of opportunistic diseases, increasing hospital admissions, increasing infections in the population (by HIV and other pathogens), or contributing to mother to child transmission of HIV. The expected increase in morbidity and mortality will be a greater cost in patient care, a cost which will be significantly higher in the more immunosuppressed patients. Therefore, the enforcement of the Royal Decree-Law will be much less cost-effective in the short term than was expected, and will negatively affect our country's public health, especially for those patients infected with HIV who will not be covered, thus increasing healthcare medium to long term costs, and moving away from the international health goals that were established.

Abstract
INTRODUCTION The number of HIV-positive immigrants have increased in Spain in the last few years, and now represent a significant proportion of the epidemic. Our objective is to describe the clinico-epidemiological characteristics of HIV-positive immigrants seen in a specialist unit in Madrid. MATERIAL AND METHODS Retrospective study. Every patient born in a country other than Spain and attended an HIV Unit in Madrid between 1992 and 2009 was included. RESULTS Of the 371 patients included, 53.1% were Latin Americans, 24.5% Sub-Saharan Africans, and 22.4% others), and 60% were males. Immigrants represented 0.3% of new patients in 1992 and rose to 49.2% in 2009. The principal reason for HIV testing had been pregnancy/delivery among women (32.7%) and having a category-B disease among men (17.4%). Sexual transmission accounted for 92% of patients. Tuberculosis was the principal AIDS-diagnosing illness. Respectively 90%, 7.7%, 60%, 26.7%, 96% and 95% of patients had an IgG for HAV, HCV, Toxoplasma, Treponema, CMV and VZV. VHB-Ags+: 5.4%; PPD+: 17%. At least one syphilis episode was recorded in 62% of the men who have sex with men (MSM). Prevalence of HLA-B5701 was 6%, 0.9% and 3.8% in Caucasians, Amerindians and Afro-Americans, respectively. CONCLUSIONS Immigrants represent a significant proportion of new HIV-positive patients. It is a very heterogeneous group according to their clinical and epidemiological characteristics.

Abstract
Compared to the incidence in adults, cryptococcosis is inexplicably rare among children, even in sub-Saharan Africa, which has the highest prevalence of coinfection with HIV and Cryptococcus neoformans. To explore any mycological basis for this age-related difference in the incidence of cryptococcosis, we investigated isolates of C. neoformans recovered from pediatric and adult patients during a 2-year period in South Africa. From reports to the Group for Enteric, Respiratory, and Meningeal Disease Surveillance in South Africa (GERMS-SA), we reviewed all cases of cryptococcosis in 2005 and 2006. We analyzed one isolate of C. neoformans from each of 82 pediatric patients (<15 years of age) and determined the multilocus sequence type (ST), mating type, ploidy, and allelic profile. This sample included isolates of all three molecular types of serotype A or C. neoformans var. grubii (molecular types VNI, VNII, and VNB) and one AD hybrid. Seventy-seven (94%) of the strains possessed the MATα mating type allele, and five were MATa. Seventy-five (91%) were haploid, and seven were diploid. A total of 24 different STs were identified. The ratios of each mating type and the proportion of haploids were comparable to those for the isolates that were obtained from 86 adult patients during the same period. Notably, the most prevalent pediatric ST was significantly associated with male patients. Overall, these pediatric isolates exhibited high genotypic diversity. They included a relatively large percentage of diploids and the rarely reported MATa mating type.

Abstract
The number of HIV infected immigrants has increased sharply in Spain. These patients are prone to contracting several different types of opportunistic infections, including bacterial, mycobacterial, fungal and parasitic infections. The present article provides an in-depth review of bacterial and fungal infections, with particular emphasis on those not endemic in our country.

Abstract
Highly-active antiretroviral therapy is effective in reducing opportunistic infections in industrialized countries. However, opportunistic parasitic infections remain the leading cause of HIV-related mortality in developing countries. These infections can also affect HIV-positive immigrants residing in Spain, as well as HIV-infected patients traveling to low-income countries. In addition, immigrants often have viral infections caused by herpesvirus, papillomavirus and polyomavirus, which are closely related to risk behaviors and commercial sex. The present article reviews the characteristics of parasitic and viral infections in patients with HIV infection with the aim of improving understanding of this vulnerable population group.

Abstract
OBJECTIVE To determine the effect of highly active antiretroviral therapy (HAART) on incidence of initial AIDS-defining illnesses (ADIs) and survival after individual ADIs. METHODS Australian AIDS notification data over the period 1993 to 2000 were examined. Analyses were based on all initial ADIs. To examine the impact of HAART, two periods of AIDS diagnosis were chosen: pre-HAART (1993-1995) and HAART (1996-2000). Comparisons between these two periods included proportion of individual ADIs, median CD4 lymphocyte counts at and survival following AIDS and individual ADIs. Median survival was based on Kaplan-Meier estimates, with examination of factors influencing survival in a Cox proportional hazards model. RESULTS Over the period 1993 to 2000 in Australia, 5017 initial ADIs were diagnosed among 4351 AIDS cases. At AIDS diagnosis, changes from the pre-HAART (1993-1995) to HAART (1996-2000) periods included an increased proportion of Pneumocystis carinii pneumonia (PCP) (25.9% to 30.4%; p =.001), AIDS dementia complex (5.2% to 6.8%; p = 0.029), non-Hodgkin lymphoma (NHL) (4.4% to 6.3%; p =.005), and tuberculosis (0.5% to 2.7%; p <.0005). Median survival following AIDS increased from 19.6 months for AIDS cases diagnosed in 1993 to 1995 to 39.6 months for AIDS cases diagnosed in 1996 to 2000 (p <.0005). Median survival was stable for NHL (7.5-8.8 months; p =.26), but increased significantly for almost all other ADIs. CONCLUSIONS An increased proportion of PCP relative to other ADIs suggests an increasing proportion of AIDS patients not receiving specific prophylaxis, presumably because of "late" HIV diagnosis. Survival following almost all ADIs has increased in the era of HAART, although the prognosis after NHL remains extremely poor.
