[Post COVID-19 Pandemic Care for HIV Caregivers].

The COVID-19 pandemic that swept the world in 2020 has highlighted the dangers and challenges posed by infectious diseases and encouraged healthcare providers to further re-think the stigma of epidemic and pandemic diseases. HIV infection was reclassified as a chronic disease in Taiwan after highly active antiretroviral therapy was introduced in the country. Because HIV infection is related to behavior, people living with HIV are often affected by a negative social image that is influenced by multiple stereotypes and the general stigma toward AIDS. In Taiwan, this stigma is deeply influenced by Eastern philosophy and Confucian culture, making the context and effect of stigma different from Western countries. The current "U=U" concept of HIV treatment holds that someone under treatment for HIV with an undetectable HIV viral load cannot sexually transmit the virus to others. Therefore, in the post-pandemic era, HIV medical care personnel should apply evidence-based-care thinking. This article describes HIV stigma in the context of Confucianism, U=U as the leading concept of HIV treatment, and the recommended approach to care for HIV healthcare practitioners in the post-COVID-19 era. Reducing HIV stigma will enable Taiwan to achieve the ' Three Zeros' of zero discrimination, zero infection, and zero death advocated by the Joint United Nations Program on HIV/AIDS for ending the AIDS epidemic by 2030.

[Ideal Medication-Readiness Cutoff Score for Initiating Antiviral Therapy in HIV Patients].

BACKGROUND: There has been a global consensus since 2016 that antiretroviral therapy (ART) should be initiated following HIV diagnosis regardless of CD4-count test results. Identifying an instrument that is able to accurately assess the readiness of HIV-infected persons for treatment initiation is thus critical. PURPOSE: (1) To evaluate the comparative readiness of patients receiving ART and those who are not yet on ART; (2) to evaluate the respective readiness variation within these 2 groups over a one-year period; and (3) to identify the cutoff value for medication readiness that indicates the ideal time to initiate ART. METHODS: A multicenter cohort study design was conducted and 297 newly diagnosed patients with HIV were enrolled at four time points, including: baseline and at 1, 3-6, and 9-12 months after ART initiation. Data collection included a demographics datasheet, the Chinese version of the HIV Medication Readiness Scale (HMRS), and 2 items, readiness to take ART for a long period of time and confidence in adhering to ART, which were scored using a 10-point Likert scale. RESULTS: Overall, 224 (75.4%) of the participants had initiated ART. Over time, the medication readiness of participants with ART initiation had increased significantly over that of non-ART user (p < .001). The mean scores of the 2-item self-rated readiness scale for patients with ART initiation were significantly greater than those without (p < .001). The cutoff values for HMRS, self-rating readiness for ART, and confidence in adherence to ART were 23.5, 5.5, and 6.5, respectively. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The optimal cutoff value of the Chinese version HMRS for evaluating HAART initiation among persons with HIV infection was 23.5. HIV healthcare professionals may apply the Chinese version HMRS and the two simple self-rated items as a clinical tool for quickly assessing the initiation of ART in people living with HIV.

[Applying the Modified Delphi Technique to Develop the Role of HIV Case Managers and Essential Nursing Competencies in HIV Care].

BACKGROUND: Since 2005, the Taiwan Centers for Disease Control (Taiwan CDC) initiated an HIV case management program in AIDS-designated hospitals to provide integrative services and risk-reduction counseling for HIV-infected individuals. In light of the increasingly complex and highly specialized nature of clinical care, expanding and improving competency-based professional education is important to enhance the quality of HIV/AIDS care. PURPOSE: The aim of this study was to develop the essential competency framework for HIV care for HIV case managers in Taiwan. METHODS: We reviewed essential competencies of HIV care from Canada, the United Kingdom, and several African countries and devised descriptions of the roles of case managers and of the associated core competencies for HIV care in Taiwan. The modified Delphi technique was used to evaluate the draft framework of these roles and core competencies. A total of 15 HIV care experts were invited to join the expert panel to review and rank the draft framework. RESULTS: The final framework consisted of 7 roles and 27 competencies for HIV case managers. In Round 1, only 3 items did not receive consensus approval from the experts. After modification based on opinions of the experts, 7 roles and 27 competencies received 97.06% consensus approval in Round 2 and were organized into the final framework for HIV case managers. These roles and associated core competencies were: HIV Care Expert (9 competencies), Communicator (1 competency), Collaborator (4 competencies), Navigator (2 competencies), Manager (4 competencies), Advocate (2 competencies), and Professional (5 competencies). CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The authors developed an essential competency framework for HIV care using the consensus of a multidisciplinary expert panel. Curriculum developers and advanced nurses and practitioners may use this framework to support developments and to ensure a high quality of HIV care.

Immune reconstitution inflammatory syndrome of Kaposi's sarcoma in an HIV-infected patient.

We present a case of Kaposi's sarcoma-related immune reconstitution inflammatory syndrome in an HIV-infected patient who developed fever, worsening pulmonary infiltrates with respiratory distress, and progression of skin tumors at the popliteal region and thigh that resulted in limitation on movement of the right knee joint at 3.5 months following a significant increase of CD4 count after combination antiretroviral therapy.

Seroprevalence of hepatitis virus infection in men who have sex with men aged 18-40 years in Taiwan.

BACKGROUND/PURPOSE: Men who have sex with men (MSM) are at increased risk for hepatitis A virus (HAV), hepatitis B virus (HBV), and hepatitis C virus (HCV) infections than the general population. Comparisons of the seroprevalence rates of these hepatitis viruses between HIV-positive and HIV-negative MSM are rarely performed in Taiwan. METHODS: Between January 2009 and June 2010, data on the serologies for HAV, HBV, and HCV were collected from two groups of patients: HIV-negative MSM, aged 18-40 years, who sought voluntary counseling and testing (VCT) for HIV infection, and HIV-positive MSM of the same age group who sought HIV care at the National Taiwan University Hospital. Both groups of patients were also tested for syphilis. RESULTS: During the 18-month study period, 690 HIV-negative MSM and 438 HIV-positive MSM were enrolled and tested for anti-HAV antibody, HBV surface antigen (HBsAg), hepatitis B core antibody (anti-HBc antibody), and anti-HCV antibody. HIV-positive MSM were older than HIV-negative MSM (30.5 ± 5.4 vs. 25.8 ± 4.7 years, p < 0.01). For HIV-positive MSM, the mean CD4 lymphocyte count was 477.6 ± 230.0 cells/µL and 46% of them had undetectable plasma HIV RNA load (< 40 copies/mL by reverse transcription-polymerase chain reaction assay). The overall seroprevalence rates of HAV, HBsAg, and HCV in HIV-positive MSM were 15.1%, 16.4%, and 5.5%, respectively, while in HIV-negative MSM, they were 7.4%, 6.2%, and 0.4%, respectively. In the multivariate analysis, age was significantly associated with seropositivity for HAV (OR [per one age group increase]: 1.96; 95% CI: 1.6-2.5), HBsAg (OR: 2.02; 95% CI: 1.6-2.6), anti-HBc (OR: 2.68; 95% CI: 2.3-3.2), anti-HCV (OR: 1.67; 95% CI: 1.0-2.7), and anti-HBs (OR: 1.25; 95% CI: 1.0-1.5). HIV infection was associated with seropositivity for HBsAg (OR: 1.73; 95% CI: 1.1-2.7), anti-HBc (OR: 2.44; 95% CI: 1.8-3.3), HCV (OR: 8.91; 95% CI: 2.5-31.4), and syphilis (OR: 11.21; 95% CI: 6.7-18.9). CONCLUSION: HIV-positive MSM have a higher seroprevalence rate of HBV and HCV infection than HIV-negative MSM in Taiwan. Vaccination and safe-sex counseling should be provided to prevent the transmission of hepatitis viruses among MSM who may be engaged in high-risk behaviors.

Maximising the potential of voluntary counselling and testing for HIV: sexually transmitted infections and HIV epidemiology in a population testing for HIV and its implications for practice.

OBJECTIVES: This study aimed to describe the epidemiology of HIV infection and sexually transmitted infections (STIs) among persons who attended voluntary counselling and testing (VCT) service for HIV and to assess whether the VCT programme reached the right population at risk in Taiwan. METHODS: From 2006 to 2010, questionnaire interview, integrated pretesting and post-testing counselling, followed by serological tests for HIV, Treponema pallidum and Entamoeba histolytica were performed for all VCT clients; additional tests for Chlamydia trachomatis and Neisseria gonorrhoeae using PCR assays of urine specimens were provided when the assays became available in two periods. RESULTS: During the study period, 10 198 VCT attendances occurred in 6863 clients, in whom 1685 (24.6%) had re-attendances. Male clients, men who have sex with men and clients with one-night stand and casual sexual partners were more likely to re-attend VCT service in the next 12 months. The overall STI prevalence was 3.5% for HIV infection, 2.2% syphilis, 1.0% amoebiasis, 4.7% chlamydia and 0.7% gonorrhoea. In logistic regression model, men who have sex with men were consistently independently associated with HIV infection, syphilis and amoebiasis. Among the repeaters, the incidence rate of HIV infection and syphilis was 3.4 and 1.6 per 100 person-years of follow-up, respectively. In Cox regression analysis, clients who used illicit non-injection recreational drugs and who practiced unprotected anal sex were at significantly higher risk of acquiring HIV infection and syphilis. CONCLUSIONS: With higher rates of re-attendances and STIs, the VCT programme reached the population most at risk for HIV and STIs compared with other screening programmes in Taiwan. The potential of VCT programme can be maximised in the prevention and control of HIV infection and STIs by providing tests for more STIs and counselling to avoid use of recreational drugs and to promote safe sex.

Evaluation of macrolide resistance and enhanced molecular typing of Treponema pallidum in patients with syphilis in Taiwan: a prospective multicenter study.

Studies of macrolide resistance mutations and molecular typing using the newly proposed enhanced typing system for Treponema pallidum isolates obtained from HIV-infected patients in the Asia-Pacific region are scarce. Between September 2009 and December 2011, we conducted a survey to detect T. pallidum using a PCR assay using clinical specimens from patients with syphilis at six major designated hospitals for HIV care in Taiwan. The T. pallidum strains were genotyped by following the enhanced molecular typing methodology, which analyzed the number of 60-bp repeats in the acidic repeat protein (arp) gene, T. pallidum repeat (tpr) polymorphism, and the sequence of base pairs 131 to 215 in the tp0548 open reading frame of T. pallidum. Detection of A2058G and A2059G point mutations in the T. pallidum 23S rRNA was performed with the use of restriction fragment length polymorphism (RFLP). During the 2-year study period, 211 clinical specimens were obtained from 136 patients with syphilis. T. pallidum DNA was isolated from 105 (49.8%) of the specimens, with swab specimens obtained from chancres having the highest yield rate (63.2%), followed by plasma (49.4%), serum (35.7%), and cerebrospinal fluid or vitreous fluid (18.2%) specimens. Among the 40 fully typed specimens, 11 subtypes of T. pallidum were identified. Subtype 14f/f (18 isolates) was the most common isolates, followed by 14f/c (3), 14b/c (3), and 14k/f (3). Among the isolates examined for macrolide resistance, none had the A2058G or A2059G mutation. In conclusion, we found that type 14 f/f was the most common T. pallidum strain in this multicenter study on syphilis in Taiwan and that none of the isolates exhibited 23S rRNA mutations causing resistance to macrolides.

Trends of transmitted drug resistance of HIV-1 and its impact on treatment response to first-line antiretroviral therapy in Taiwan.

OBJECTIVES: To determine the impact of transmitted drug resistance (TDR) of HIV-1 on treatment outcome in areas where routine testing for drug resistance mutations may not be available before combination antiretroviral therapy (cART) is initiated. METHODS: Genotypic resistance assays were performed on HIV isolates from archived blood samples obtained from 1349 antiretroviral-naive HIV-1-infected patients in Taiwan from 2000 to 2010. Resistance mutations were interpreted with the use of the HIVdb program of the Stanford University HIV Drug Resistance Database. The genotypic sensitivity score (GSS) of the regimens prescribed was calculated. A matched case-control study was conducted to assess the impact of TDR on treatment outcomes. RESULTS: The overall prevalence of TDR to any antiretroviral agent was 8.0%, declining from 12.3% in 2003-06 to 5.1% in 2007-10. In the matched case-control study, 31 patients with high- or intermediate-level resistance, 16 with low-level resistance and 89 controls were enrolled. Compared with regimens with GSS >2.5, initiation of regimens with GSS ≤2.5 was associated with a higher treatment failure rate (39.3% versus 15.7%, P = 0.02) and shorter time to treatment failure (log-rank P < 0.001). In patients receiving regimens with GSS ≤2.5, protease inhibitor-based regimens were less likely to result in treatment failure, compared with non-nucleoside reverse-transcriptase inhibitor-based regimens (hazard ratio 0.26, 95% CI 0.06-1.12, P = 0.07). CONCLUSIONS: In Taiwan the prevalence of TDR of HIV-1 strains declined and stabilized between 2007 and 2010. Receipt of antiretroviral regimens with GSS ≤2.5 was associated with poorer treatment responses than regimens with GSS >2.5.

Metabolic syndrome among HIV-infected Taiwanese patients in the era of highly active antiretroviral therapy: prevalence and associated factors.

OBJECTIVES: Metabolic complications related to antiretroviral therapy are rarely investigated among HIV-infected patients in Asian countries. We investigated the prevalence of and factors associated with metabolic syndrome among HIV-infected patients who are ethnic Chinese in the era of highly active antiretroviral therapy (HAART). METHODS: A cross-sectional survey was performed to collect information on the demographic and clinical characteristics and antiretroviral therapy prescribed in 877 HIV-infected patients at a university hospital in Taiwan from May 2008 to April 2009. The modified Adult Treatment Panel III criteria were used to define metabolic syndrome after adjusting for the waist circumference criteria for Asians. RESULTS: Of the 877 patients, 75.3% were male homosexuals, 80.7% were receiving HAART and 88.7% had CD4 counts ≥ 200 cells/mm(3). Metabolic syndrome was diagnosed in 210 patients (26.2%). After adjusting for age, gender, smoking status, family history of diabetes mellitus, cardiovascular disease and hypertension, and baseline CD4 and plasma HIV RNA load, use of protease inhibitors (PIs) was significantly associated with the presence of metabolic syndrome (OR 1.63; 95% CI 1.10-2.43). In addition, exposure to PI for ≥ 3 years, to HAART for ≥ 6 years and to nucleoside reverse transcriptase inhibitor(s) for ≥ 6 years was significantly associated with the presence of metabolic syndrome with an adjusted OR of 1.96 (95% CI 1.13-3.42), 1.78 (95% CI 1.03-3.07), and 1.91 (95% CI 1.11-3.30), respectively. CONCLUSIONS: Approximately one-fourth of HIV-infected Taiwanese patients developed metabolic syndrome in the HAART era. Receipt of HAART and prolonged exposure to PI and nucleoside reverse transcriptase inhibitor(s) were associated with metabolic syndrome.

Recent hepatitis C virus infections in HIV-infected patients in Taiwan: incidence and risk factors.

Outbreaks of sexually transmitted hepatitis C virus (HCV) infections have been recently reported in HIV-infected men who have sex with men (MSM) in Europe, Australia, and North America. Little is known concerning whether this also occurs in other Asia-Pacific countries. Between 1994 and 2010, a prospective observational cohort study was performed to assess the incidence of recent HCV seroconversion in 892 HIV-infected patients (731 MSM and 161 heterosexuals) who were not injecting drug users. A nested case-control study was conducted to identify associated factors with recent HCV seroconversion, and phylogenetic analysis was performed using NS5B sequences amplified from seroconverters. During a total followup duration of 4,270 person-years (PY), 30 patients (3.36%) had HCV seroconversion, with an overall incidence rate of 7.03 per 1,000 PY. The rate increased from 0 in 1994 to 2000 and 2.29 in 2001 to 2005 to 10.13 per 1,000 PY in 2006 to 2010 (P < 0.05). After adjustment for age and HIV transmission route, recent syphilis remained an independent factor associated with HCV seroconversion (odds ratio, 7.731; 95% confidence interval, 3.131 to 19.086; P < 0.01). In a nested case-control study, seroconverters had higher aminotranferase levels and were more likely to have CD4 ≥ 200 cells/µl and recent syphilis than nonseroconverters (P < 0.05). Among the 21 patients with HCV viremia, phylogenetic analysis revealed 7 HCV transmission clusters or pairs (4 within genotype 1b, 2 within genotype 2a, and 1 within genotype 3a). The incidence of HCV seroconversion that is associated with recent syphilis is increasing among HIV-infected patients in Taiwan.

Late diagnosis of human immunodeficiency virus infection in the era of highly active antiretroviral therapy: role of socio-behavioral factors and medical encounters.

BACKGROUND/PURPOSE: Despite provision of free-of-charge human immunodeficiency virus (HIV) care and antiretroviral therapy in Taiwan, a substantial proportion of patients experience late HIV diagnosis. We investigated the risk factors for late HIV diagnosis in Taiwan. METHODS: Structured interviews were conducted among newly diagnosed HIV-infected patients to collect data on demographics, socio-behavioral variables and clinical profiles within 1 year preceding HIV diagnosis from August 2006 to July 2008. Multivariate analysis was performed to identify factors associated with missed opportunities for HIV testing and late HIV diagnosis (< 200 CD4 cells/µL). RESULTS: Among 227 newly diagnosed HIV-infected patients, 107 (47%) had late HIV diagnosis. Patients who had first positive tests for HIV at voluntary testing sites [odds ratio (OR): 0.22; 95% confidence interval (CI): 0.10-0.50], regular sexual partners at HIV diagnosis (OR: 0.30; 95% CI: 0.14-0.68), and unprotected sex in the preceding 3 months (OR: 0.16; 95% CI: 0.07-0.34) were less likely to have late HIV diagnosis. Missed opportunities for HIV testing after seeking medical attention occurred in 47 patients (20.7%) and were more common in patients with late HIV diagnosis than in those who received an earlier diagnosis (23.0% vs. 15.8%, p = 0.03). Patients with late HIV diagnosis were more likely than their counterparts to have received a diagnosis of seborrheic dermatitis (7.4% vs. 0.8%, p = 0.02) and community-acquired pneumonia (5% vs. 0%, p = 0.02), for which HIV testing was not offered by the health care providers. CONCLUSION: Late HIV diagnosis is not uncommon in Taiwan. Regular risk assessment and provision of routine HIV testing in medical encounters and increase of accessibility to voluntary HIV testing could facilitate earlier diagnosis of HIV infection.
