The US Military HIV Natural History Study: Informing Military HIV Care and Policy for Over 30 Years.

In October 1985, 4 years after the initial descriptions of the acquired immunodeficiency syndrome (AIDS), the U.S. Department of Defense (DoD) began routine screening for human immunodeficiency virus (HIV) infection to prevent infected recruits from exposure to live virus vaccines, implemented routine active-duty force screening to ensure timely care and help protect the walking blood bank, and initiated the U.S. Military HIV Natural History Study (NHS) to develop epidemiologic, clinical, and basic science evidence to inform military HIV policy and establish a repository of data and specimens for future research. Here, we have reviewed accomplishments of the NHS over the past 30 years and sought to describe relevant trends among NHS subjects over this time, with emphasis on combination antiretroviral therapy (cART) use and non-AIDS comorbidities. Subjects who were prospectively enrolled in the NHS from 1986 through 2015 were included in this analysis. Time periods were classified by decade of study conduct, 1986-1995, 1996-2005, and 2006-2015, which also correlate approximately with pre-, early-, and late-combination ART (cART) eras. Analyses included descriptive statistics and comparisons among decades. We also evaluated mean community log10 HIV viral load (CVL) and CD4 counts for each year. A total of 5,758 subjects were enrolled between 1986 and 2015, of whom 92% were male with a median age of 28 years, and 45% were African-American, 42% Caucasian, and 13% Hispanic/other. The proportion of African-Americans remained stable over the decades (45%, 47%, and 42%, respectively), while the proportion of Hispanic/other increased (10%, 13%, and 24%, respectively). The CD4 count at HIV diagnosis has remained high (median 496 cells/uL), while the occurrence of AIDS-defining conditions (excluding low CD4 count) has decreased by decade (36.7%, 5.4%, and 2.9%, respectively). Following the introduction of effective cART in 1996, CVL declined through 2000 as use increased and then plateaued until guidelines changed. After 2004, cART use again increased and CVL declined further until 2012-15 when the vast majority of subjects achieved viral suppression. Non-AIDS comorbidities have remained common, with approximately half of subjects experiencing one or more new diagnoses overall and nearly half of subjects diagnosed between 2006 and 2015, in spite of their relatively young age, shorter median follow-up, and wide use of cART. The US Military HIV NHS has been critical to understanding the impact of HIV infection among active-duty service members and military beneficiaries, as well as producing insights that are broadly relevant. In addition, the rich repository of NHS data and specimens serves as a resource to investigators in the DoD, NIH, and academic community, markedly increasing scientific yield and identifying novel associations. Looking forward, the NHS remains relevant to understanding host factor correlates of virologic and immunologic control, biologic pathways of HIV pathogenesis, causes and consequences of residual inflammation in spite of effective cART, identifying predictors of and potential approaches to mitigation of excess non-AIDS comorbidities, and helping to understand the latent reservoir.

Challenges to eliminating the AIDS pandemic in China.

Based on data from the Chinese Center for Disease Control and Prevention (CDC), there were a total of 861,042 people with human immunodeficiency virus (HIV)/ immune deficiency syndrome (AIDS) as of December 31, 2018 in China, a total of 148,589 new HIV infections, and 38,134 AIDS-related deaths in the year 2018. As of 2017, only 74% of people living with HIV knew their status, 80% of people living with HIV were receiving treatment, and 91% were virally suppressed in China. Although mankind has made great progress in the fight against AIDS in recent years, the vision of ending the AIDS epidemic still faces many challenges in China. Due to the huge population and the imbalance in the prevalence of HIV/AIDS in China, expanding HIV screening and early detection remains the key to Chinas response to HIV. Limitations of antiviral therapy (ART), rejection or discontinuation of an immediate ART strategy by people infected with HIV, and the difficult search for a cure for AIDS all limit the coverage and quality of treatment. The high price of drugs and lack of vaccines present enormous challenges; social discrimination still exists, and participation by non-governmental organizations in prevention, treatment, and care is limited. As part of the future response to HIV, HIV eradication programs should continue to be explored, and attention should be paid to long-term care for people living with HIV.

1284. Pre-exposure Prophylaxis (PrEP) for HIV in Vermont: an Assessment of Prescribing in a Uniquely Rural State

BackgroundIn the United States and Vermont, men who have sex with men (MSM) make up the majority of new human immunodeficiency virus (HIV) infections every year. Despite HIV prevention campaigns and approval of antiviral therapy for pharmacologic HIV pre-exposure prophylaxis (PrEP), HIV cases in Vermont—a predominantly rural state—are on the rise. The primary objective of this study was to assess prescribing practices and barriers surrounding PrEP for adult MSM in Vermont.MethodsA web-based healthcare provider survey was deployed electronically over a 10 week period in 2019 to a convenience sample of licensed primary care, sexual health, and infectious disease providers in Vermont. Questions were designed to target factors thought to influence PrEP prescribing, with a focus on prescribing behaviors and perceived barriers.ResultsAn estimated 500 providers received the survey. There were 137 survey respondents, 106 (77%) were physicians, primarily in internal medicine. Though only 47 (34%) providers had experience prescribing PrEP to MSM patients, over 89% identified as willing to prescribe PrEP to high-risk groups. Among PrEP prescribers, screening frequency for HIV and bacterial sexually transmitted infections (STIs) while on PrEP fell below the current guideline recommendations at 72% and 53%, respectively. Less than 70% of providers routinely obtain sexual history for male patients. Among providers willing to prescribe PrEP, concern regarding medication toxicity was the only statistically significant barrier (χ 2 = 5.5, P = 0.02). Concerns regarding risk compensation behavior and lack of knowledge or experience regarding prescribing PrEP also demonstrated an association with provider willingness to prescribe PrEP, however did not reach statistical significance.ConclusionThe majority of Vermont providers sampled are willing to prescribe PrEP, suggesting there is great opportunity to increase prescribing and use, potentially having an impact on reducing HIV transmission among MSM in the state. Provider education targeted toward guidelines for STI and HIV screening on therapy, obtaining sexual histories, and minimal toxicity risk may serve to increase prescribing of PrEP among Vermont providers.Disclosures All authors: No reported disclosures.

320. UK-HOPS (HIV Osteoporosis Prevention and Screening)-Gaps in the Care of HIV Patients with Bone Disease

BackgroundWith increasing life expectancy among people living with Human Immunodeficiency Virus (HIV), long-term complications such as osteoporosis/osteopenia and fractures are frequently seen. Although screening guidelines exist for bone disease in the HIV population, quantitative and qualitative gaps exist in screening and prevention. Bone disease in HIV is multifactorial, and FRAX may not accurately predict fracture risk. The aim of our study is to describe diagnostic features of bone disease and estimate the population at risk, and evaluate the frequency of screening, referral and treatment in patients attending an HIV Clinic.MethodsWe performed a retrospective analysis of 1220 patients with HIV infection ≥40 years of age who attended the HIV clinic under the Ryan White program, during January 2016 to December 2018, at University of Kentucky. We obtained demographic details (Table 1), comorbidities, laboratory testing, bone mineral density (BMD) testing and specialty bone clinic referral data from electronic health records, applying ICD -10 and CPT codes. We estimated the frequency of BMD measurement and prevalence of risk factors for bone disease specific to this population.ResultsBMD testing was performed in only 158 (13%) patients (CMS targets 60% for testing at-risk populations). Of these patients, 76 (48%) had osteopenia and 59 (37%) had osteoporosis; 22 (14%) received treatment (Figure 1). Seven patients with osteoporosis/osteopenia and fracture had bone biopsy, with low bone turnover in four (57%). Potential risk factors for secondary osteoporosis are presented in Table 2; at least one factor was present in 98% of patients. Fracture prevalence was likely underestimated because the ICD-10 /CPT coding was available only in 23 (2%) patients.ConclusionBone disease is under-recognized and undertreated, and targeted screening programs are needed for earlier diagnosis and management in this population. Bisphosphonates may not be optimal first-line therapy for all HIV patients with bone loss. In addition to stress or fragility fractures and worsening osteoporosis, metabolic bone work-up should be performed in patients with secondary osteoporosis related to CKD, renal phosphate loss, prior bisphosphonate/Tenofovir/glucocorticoid treatment.

307. Overcoming Hepatitis C Elimination Challenges in the Coachella Valley through the Collaboration of Linkage to Care, a Managed Care Organization, and a Federally Qualified Health Center

BackgroundPer the Centers for Disease Control and Prevention, 2.4 million Americans have the hepatitis C virus (HCV). New cases increased by 14% from 2014 to 2016 in California with 400,000 infections, 4,000 infections in the Coachella Valley and about 50% unaware of their diagnosis. A barrier to elimination is the lack of rapid screenings and linkage to care (LTC) of infected individuals into an integrated system. Thus, we developed a program at the Hepatitis Center of Excellence (HCE) where pharmacists in a managed care organization (MCO) provide opportunities to overcome these boundaries. The partnership of the MCO and federally qualified health center (FQHC) was established in 2017 to expand access to care to the HCV community. We anticipate that our program will eliminate HCV in the Coachella Valley by modeling past success in human immunodeficiency virus (HIV) testing and LTC at the FQHC through an interdisciplinary approach.MethodsA single-center, retrospective analysis from January 2017 to December 2018 of HCV individuals was conducted at the pharmacist-led HCE in Palm Springs, California. The LTC team approached barriers through prompt free screenings and major advocacy. Pharmacists and specialty physicians collaborated to ensure rapid assessment, treatment initiation and completion, and sustained virologic response (SVR). The HCE has adapted the HIV testing and LTC model in hopes of achieving similar feats. From 2014 to 2018, 92,947 total HIV tests were performed with 90.2% of HIV-positive patients linked to care. HCV testing was then added to HIV screening and expanded to other testing sites.ResultsThe first visit with a clinical pharmacist consists of education, reviewing lab tests, cost assistance, and providing treatment options. From 2017 to 2018, 169 of 172 HCV positive individuals (98.2%) achieved SVR by treatment completion. The HCV LTC program demonstrated a 3.8% increase in HCV testing from 2017 to 2018.ConclusionPharmacist-led care for a large volume of HCV patients allows time for specialty physicians to manage more complex cases. The collaboration between the FQHC, MCO, and LTC team showed HCV elimination is possible based on high SVR rates. HCE is projecting successful linkages to care and continuous campaigning for individuals to be treated for HCV in the Coachella Valley.Disclosures All authors: No reported disclosures.

Long-term results achieved by guideline-based stage-dependent management of anal cancer in a non-HIV population.

Therapy of anal cancer follows national and international guidelines that are mainly derived from randomized trials. This study aimed to analyze long-term results of stage-dependent treatment of anal cancer in a non-selected patient cohort. All consecutive patients treated for anal cancer between 2000 and 2015 were retrieved from a prospective database. Risk-dependent screening for human immunodeficiency virus showed no infection. Main outcome measure was overall survival with respect to tumor site and treatment. Secondary endpoints were cause-specific survival, stoma free survival, and the rate of salvage operations. In total, 106 patients were treated for anal cancer. Of those, 69 (65.1%) suffered from anal canal cancer and 37 (34.9%) from anal margin cancer. Three patients with synchronous distant metastases were excluded from analysis. The majority of patients (n = 79, 76.7%) were treated by chemoradiotherapy in curative intention. Twenty-two patients underwent local surgery. Five-year overall survival was 73.1% and cause-specific survival at 5years was 87.4%. Overall, 14 patients (13.6%) needed salvage surgery. Their 5-year cause-specific survival was 57.7%. A permanent ostomy was avoided in 77.7%. Treatment of anal cancer results in low rates of salvage surgery and permanent ostomies, when therapy was determined by a multidisciplinary team following national and international guidelines.

Evolution of an Electronic Health Record Based-Human Immunodeficiency Virus (HIV) Screening Program in an Urban Emergency Department for Diagnosing Acute and Chronic HIV Infection.

Since 2006, Centers for Disease Control and Prevention guidelines recommend routine opt-out human immunodeficiency virus (HIV) testing among sexually active 13- to 64-year-olds. Earlier diagnosis and treatment of HIV infection reduces morbidity and mortality and can limit transmission to others. Our aim was to increase HIV testing, diagnosis, and linkage to care in the emergency department (ED). Beginning May 4, 2015, we utilized our electronic health record (EHR) to enhance HIV testing in patients seen in the Rush University Medical Center emergency department in Chicago, IL, who were 13-64years of age, did not have HIV listed on their problem list, and did not have an HIV antigen/antibody (Ag/Ab) test in the EHR within the past rolling 12-month period. Strategies included use of a "Best Practice Advisory" and later auto-order screening linked to a complete blood count order. Our baseline HIV test rate was 2.5% of the target population by age (average of 93 tests per month). From May 4, 2015 to January 31, 2019, 137,749 patients of 240,091 ED visits met our test criteria and 23,588 (17.1% of the target population) HIV Ag/Ab tests were performed, resulting in 164 positive tests. We identified 18 acute seroconverters, 51 new chronically infected persons, and 95 known infected, many of who had not disclosed their status. Our positive test rate was 0.70%, which dropped to 0.29% if only newly diagnosed individuals were counted. EHR enhancements in a large urban ED identifies both newly diagnosed acute and chronically HIV-infected persons. Identification of previously diagnosed patients offers an opportunity to relink them to care.

Experiences of Screening for Human Immunodeficiency Virus, Viral Hepatitis B, and Viral Hepatitis C Infections at a Hospital in Thailand: Test Utilization and Outcomes.

BackgroundTo prevent the transmission of HIV and hepatitis B and C viruses, early detection is necessary; however, in the early stage, most infected people are symptomless. Screening for these infections should be targeted to certain clinical settings to increase the early detection rate.Material/MethodsThis retrospective study was conducted by analyzing data from patients’ medical records to determine how the screening tests for these viral infections were utilized and what the clinical outcomes from the test utilization were.ResultsFrom 11 676 collected records, the screening tests for HIV, HBV, and HCV infections were utilized in 871, 556, and 236 cases, respectively. The tests for HIV and HCV were utilized the most in people with chronic non-infectious diseases, while the test for HBV infection was utilized the most in pregnant women. The positive results of these tests were highly found in the group of patients with acute non-infectious diseases. HIV infection was newly detected in 1.38% of patients, and HBV and HCV infections were newly detected in 5.58% and 2.12%, respectively.ConclusionsScreening for HIV and HBV infections was performed according to the guidelines of the national HIV and HBV programs. The Outpatient Department (OPD) and medical ward may be the most appropriate clinical settings for HIV screening because most patients are there and blood tests are often ordered there, too. The national programs helped slow the rates of HIV and HBV infections in this community.

Team Triage Intervention, Including Licensed Practical Nurse, to Increase HIV Testing Rates in the Emergency Department: A Quality Improvement Project

IntroductionEmergency departments have an important role in screening for human immunodeficiency virus infection and reducing the morbidity, mortality, and transmission of the human immunodeficiency virus. There are debates about human immunodeficiency virus screening, including opt-in, opt-out, and active choice models. Previous studies have shown that multiple factors affect the patient rate of acceptance, including where, when, and by whom the screening is offered. The purpose of this quality improvement project was to test a team-based triage intervention to improve the amount of HIV testing done in our emergency department. MethodsThe design was a single site quality improvement intervention with post-intervention monthly rates compared to historic monthly rate controls. The intervention focused on the introduction of a Licensed Practical Nurse in addition to the current triage process and personnel. The percentage of patients receiving human immunodeficiency virus testing and the number of tests sent per month before and after the implementation of the intervention were measured. ResultsOur results show that 0.6% (SD < 0.01) and 2.5% (SD 2.2) of patients received human immunodeficiency virus testing before and after implementation of the intervention, respectively (χ2 = 501.76, P < 0.05). A mean of 37.4 (SD = 12.91) and 151.3 (SD = 33.34) human immunodeficiency virus tests were sent per month before and after implementation of the intervention, respectively (t = 8.53, P < 0.001). DiscussionThis process intervention, in which licensed practical nurses offered human immunodeficiency virus screening tests during team triage, resulted in a 3-fold increase in the percentage of patients being tested for human immunodeficiency virus.

Primary care provider adherence to reproductive healthcare guidelines in adolescents and young adults with disabilities: A retrospective matched cohort study1.

Assessing provider adherence to preventative sexual and reproductive healthcare guidelines in adolescents and young adults (AYA) patients with physical and intellectual disabilities (PWD). Records of PWD (N= 42) age 12-26 receiving health maintenance between 01/01/11-12/31/16 were reviewed for: (1) initiation and completion of human papilloma virus (HPV) vaccination series, (2) initiation and completion of meningococcal vaccination, (3) screening for human immunodeficiency virus (HIV), and documentation of (4) sexual, (5) menstrual, and (6) pregnancy histories. Unaffected age and gender-matched patients provided comparison data (Comparison Cohort, CC). The mean age of both groups was 17.3 years ± 3.8 and 40.5% were female. There was no significant difference between groups regarding the completion of HPV or meningococcal vaccine series. Among those 15+ years of age, 7.1% of PWD and 28.6% of CC were screened for HIV (p= 0.04). Sexual history was documented in 19.0% of PWD versus 73.8% of CC (p< 0.001). Among females, menstrual regularity was recorded in 11.8% of PWD versus 47.1% of CC (p= 0.02) and pregnancy history in 0.0% of PWD versus 29.4% of CC (p= 0.04). Adherence to sexual health guidelines was suboptimal, and lower among PWD. Vaccination rates did not differ between the two groups.

Screening for human immunodeficiency virus using a newly developed fourth generation lateral flow immunochromatography assay

BackgroundHigh sensitivity for detection of HIV-1 p24 antigen allows for early detection of primary HIV-1 infections. ObjectivesTo evaluate the detection sensitivity and specificity of the Daina Screen® HIV Combo assay using clinical specimens in Japan where the pretest probability (prevalence) is low. Study designWe screened 17,373 preoperative outpatient blood samples using 4th generation lateral flow immunochromatography Daina Screen® HIV Combo assay for simultaneously detecting anti-HIV-1/2 and HIV-1 p24 antigen. ResultsOf the samples tested, 24 were positive for HIV-1 p24 antigen and 49 for HIV-1/2 antibody. Of the 49 samples, 36 were WB and HIV-1 RNA negative, 10 were WB and HIV-1 RNA positive, and 3 were WB positive, HIV-1 RNA negative, and in-house HIV-1 proviral DNA positive. RT-PCR revealed that of the 24 samples that were p24 antigen positive, one sample was HIV-1 RNA positive, which was reconfirmed using an in-house HIV-1 provirus DNA assay. From the 17,300 HIV-1 p24 antigen and anti-HIV-1/2 negative samples, pools containing 10 negative samples each were tested for HIV-1 by RT-PCR; all results were negative. ConclusionThe Daina Screen® HIV Combo assay had a sensitivity and specificity of 100% and 99.7%, respectively, which sufficiently detected HIV infection in the cohort.

False-positive fourth-generation HIV test associated with autoimmune hemolytic anemia. Case report

Introduction: The fourth-generation ELISA human immunodeficiency virus (HIV) screening test has a high sensitivity and specificity &gt;99% to detect both antigens and antibodies. Estimates are that only 0.5% yield false positive results.Case description: 61-year-old female patient with a clinical picture consisting of malaise, unquantified fever, asthenia and adynamia. Laboratory tests revealed anemia, so a Coombs test was performed, obtaining a positive result along with other findings of mixed autoimmune hemolytic anemia. Two fourth-generation ELISA HIV screening tests were performed obtaining positive results. Given the national recommendations on the diagnosis of HIV infection, a viral load was performed, which turned out to be negative, so the result was considered a false positive.Discussion: Clinical and biological factors are related to false positive results. There are descriptions about autoimmunity phenomena, such as systemic lupus erythematosus or autoimmune hemolytic anemia, with few cases in older adults.Conclusions: Rapid tests have changed the diagnosis of HIV infection worldwide; however, like any other diagnostic test, they may yield false positive results with differential diagnoses, including autoimmune hemolytic anemia.

Pharmacist Comfort and Awareness of HIV and HCV Point-of-Care Testing in Community Settings.

To address the public health concern of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) transmission, various intrapersonal and organizational factors were identified to explore opportunities for pharmacists as part of a HIV/HCV prevention strategy. The awareness and comfort of pharmacists practicing in independent pharmacies and student pharmacists on providing HIV and HCV point-of-care (POC) tests in an urban setting were investigated. Surveys were anonymously completed by pharmacists practicing in independent pharmacies within a 2-mile radius of our institution and student pharmacists attending our institution. Surveys were administered over a period of 10 weeks. Data were analyzed using descriptive statistics. A total of 119 pharmacy students and 23 practicing licensed pharmacists completed the survey. Only 21.7% of pharmacists were aware that HIV and HCV screenings are available as POC tests. Pharmacists were more likely to feel comfortable administering other POC tests and not HIV or HCV POC tests. Student pharmacists felt more comfortable than pharmacists in administering HIV and HCV POC tests and had a higher perceived level of comfort of their ability to administer these tests as licensed pharmacists. In this urban setting, awareness and comfort in pharmacist-provided HIV and HCV POC testing is low, however, with proper training and education, pharmacists in these community pharmacy practice settings can expand HIV and HCV screening opportunities for the community.

Assessing the National Prevalence of HIV Screening in the United States using Electronic Health Record Data.

The Centers for Disease Control and Prevention and the U.S. Preventive Services Task Force recommend population-based screening for human immunodeficiency virus (HIV) at least once in each patient's life. National surveys estimate that 42.5% of the population has been screened; however, these studies have relatively low sample sizes and inherent survey biases. Using a national, de-identified cloud-based electronic health record (EHR) information from over 48 million patients, we found that only 6.4% of Americans over the age of 18 had laboratory evidence of a prior HIV test. Further investigation is necessary to determine if single-item questions on national surveys correlate with objective evidence of HIV testing, as well as addressing the numerous limitations related to the use of EHR data that likely grossly underestimates the prevalence of HIV screening nationally.

HIV Testing in 50 Local Jurisdictions Accounting for the Majority of New HIV Diagnoses and Seven States with Disproportionate Occurrence of HIV in Rural Areas, 2016-2017.

Since 2006, CDC has recommended universal screening for human immunodeficiency virus (HIV) infection at least once in health care settings and at least annual rescreening of persons at increased risk for infection (1,2), but data from national surveys and HIV surveillance demonstrate that these recommendations have not been fully implemented (3,4). The national Ending the HIV Epidemic initiative* is intended to reduce the number of new infections by 90% from 2020 to 2030. The initiative focuses first on 50 local jurisdictions (48 counties, the District of Columbia, and San Juan, Puerto Rico) where the majority of new diagnoses of HIV infection in 2016 and 2017 were concentrated and seven states with a disproportionate occurrence of HIV in rural areas relative to other states (i.e., states with at least 75 reported HIV diagnoses in rural areas that accounted for ≥10% of all diagnoses in the state).† This initial geographic focus will be followed by wider implementation of the initiative within the United States. An important goal of the initiative is the timely identification of all persons with HIV infection as soon as possible after infection (5). CDC analyzed data from the Behavioral Risk Factor Surveillance System (BRFSS)§ to assess the percentage of adults tested for HIV in the United States nationwide (38.9%), in the 50 local jurisdictions (46.9%), and in the seven states (35.5%). Testing percentages varied widely by jurisdiction but were suboptimal and generally low in jurisdictions with low rates of diagnosis of HIV infection. To achieve national goals and end the HIV epidemic in the United States, strategies must be tailored to meet local needs. Novel screening approaches might be needed to reach segments of the population that have never been tested for HIV.

Kaposi sarcoma in Southern Finland (2006-2018).

Kaposi sarcoma (KS) age-standardized incidence rate is below 0.3 per 100,000 in Nordic countries. Data on KS in Finland have been sparse. A retrospective review of all the patients with KS cases managed in the Helsinki University Central Hospital between 2006 and 2018. Forty patients (median age at diagnosis 45years, 38 males) were included. About 2.5 new cases were diagnosed per year (incidence 0.16 /100,000). The different subtypes of KS were: human immunodeficiency virus (HIV) (65%), classical KS (30%), and immunodepression (5%). Patients with HIV were significantly younger, more likely to have cutaneous lesions of the face, the trunk, and mucosal lesions,and KS withinlymph nodes and inner organs. KS was diagnosed at the same time as HIV in 77% of cases, 28% with CD4-cell level above 300cells/mm3 . Among the patients with classical KS (n=12), 75% were of Finnish origin, 41% had a second primary malignancy diagnosed, and 25% had noninsulin dependent diabetes mellitus. Among HIV patients, 27% had another AIDS-related illness, 7% of the patients developed lymphoproliferative disorders, and 7% a hemophagocytic syndrome. Patients with HIV were always treated with antiviral therapy, with pegylated liposomal doxorubicin in 57% of the cases. Local radiotherapy was the main treatment for other KS types. None of the 5 deaths during follow-up was related to KS. Classical KS (KS-CLA) occurs among native Finns, frequently with other present malignancies. Screening of HIV and other malignancies is warranted in new cases of KS.

A rare case of an HIV-seronegative AIDS patient with Pneumocystis jirovecii pneumonia

BackgroundAs technology progresses, several highly sensitive human immunodeficiency virus (HIV) screening kits are being researched and developed to quickly and efficiently identify serum HIV antibodies within the non-window period. In individuals who are HIV-seronegative, HIV infections that are not within a window period are rare. In such cases, all antibody detection methods will fail, and misdiagnosing these patients will have catastrophic consequences.Case presentationA 22-year-old male Chinese patient with diffuse exudative lesions in both lungs and initial symptoms of cough and dyspnoea was diagnosed with Pneumocystis jirovecii pneumonia (PJP) by aetiological examination, and the patient’s plasma CD4+ T-cell count was extremely low. In China, PJP is prevalent in HIV-infected individuals. Pneumocystis jirovecii (P. jirovecii) has a high colonisation rate in patients with HIV infections. This patient was naturally suspected of being an HIV patient; however, serum HIV antibody tests were negative using both an enzyme-linked immunosorbent assay (ELISA) and a latex agglutination assay, and HIV was not detected by western blotting. Subsequently, the plasma HIV viral load was found to be extremely high on two repeated plasma HIV RNA tests, thus confirming HIV-seronegative acquired immunodeficiency syndrome (AIDS) in this patient. With administration of effective anti-P. jirovecii treatment and highly active antiretroviral therapy (HAART) after diagnosis, the patient’s disease condition was rapidly controlled.ConclusionThis is the second reported case in China of an HIV-seronegative AIDS patient. Such cases are also rare worldwide. Although HIV-seronegative HIV infections are rare, AIDS should be considered in immunodeficient patients with opportunistic infections, even if the test results are HIV-seronegative. Plasma HIV RNA testing is important for such patients.

Usability Study of a Self-test Prototype for Human Immunodeficiency Virus (HIV) Screening

Usability Study of a Self-test Prototype for Human Immunodeficiency Virus (HIV) Screening

Sero-epidemiology and risk factors of syphilis in Makassar, Indonesia

Abstract Introduction. Syphilis is an infectious disease caused by Treponema pallidum spirochete and is mainly transmitted by sexual contact. Syphilis has the potential to cause serious complications and is closely related to human immunodeficiency virus (HIV) infection thus making syphilis still a major public health problem. In Indonesia, surveys of high-risk populations in 2007 and 2011 reported an increase in the prevalence of syphilis, especially in men who have sexual relationships with other men (MSM). Moreover, studies have described risk factors for HIV transmission including MSM, heterosexual contacts, Intravenous (IV) drug use, and infected partners. Objectives. To assess the epidemiological aspects and risk factors for syphilis in Makassar, as well as the correlation with a coinfection of other sexually transmitted infections. Material and Methods. This study is a multi-centre cross-sectional descriptive study with consecutive sampling. We evaluated cases for eligibility by confirming the diagnosis based on the serological result using rapid plasma reagin assay (RPR), Treponema pallidum haemagglutination (TPHA), and HIV screening kit. The cases were analyzed based on epidemiological features, risk factors and clinical findings, co-infection with other sexually transmitted infection (ST), and stadium of the disease. Results. A total of 79 serologically confirmed syphilis cases were collected between January 2017 and December 2018 in Makassar, the capital city of South Sulawesi province in Indonesia. Of the 63 male subjects (79.7%), 38 (48.1%) were homosexual/MSM, and in 41 cases of HIV-infected subjects, 25 (60.9%) of them were also MSM. Conclusion. Our study showed there was a significant correlation between syphilis and an increased risk of HIV transmission in MSM groups. The higher number of cases of syphilis and HIV co-infection among MSM can increase transmission of both infections and should be considered a major risk factor for syphilis in Makassar.

Mother-to-child transmission of HIV: An 11-year experience in a single center and HIV prevention effectiveness in Taiwan

Mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) has become an essential global health issue and its elimination is a crucial target. A prenatal "opt-out" HIV screening program was initiated in 2005 in Taiwan. In recent 3 years, approximate screening and MTCT rates were 99% and 2.27% (1/44), respectively. Here, we describe the clinical management of mothers infected with HIV and MTCT rate at National Taiwan University Hospital (NTUH), Taipei, Taiwan, in the years after the program was initiated. We retrospectively reviewed charts of pregnant women infected with HIV, who were managed at NTUH between January 2005 and December 2016. HIV infection status of 39 infants born to mothers infected with HIV was available. Between 2005 and December 2016, 50 pregnant women infected with HIV, with 57 parities were managed at NTUH, and 57 live infants were born. We excluded 18 parities because of missing data. Maternal antiviral treatment was administered in 37 of 39 infants. Only one infant tested positive for an HIV antibody test at 18 months, but showed definitive HIV exclusion at 20 months after a series of tests without administration of antiviral treatment. MTCT rate was 0%. Successful implementation of available perinatal HIV intervention dramatically reduced vertical transmission rate of HIV. MTCT rate was 0% in NTUH after the program. However, as NTUH is an HIV referral center, additional efforts are needed to achieve the World Health Organization criteria of lowering the vertical transmission rate of HIV to <2% in Taiwan.
