Moyamoya Syndrome Secondary to Coinfection of Meningovascular Neurosyphilis and Acquired Immunodeficiency Syndrome.

Moyamoya angiopathy is a rare cerebrovascular condition characterized by insufficient cerebral blood flow resulting from arterial vessel narrowing or occlusion, potentially leading to cerebral ischemia due to inadequate oxygen and nutrient supply to the brain tissue. The development of collateral vessels in stenotic regions, inherently fragile and prone to rupture, may further precipitate intracerebral hemorrhage. Alongside focal neurological symptoms, the common clinical presentations of Moyamoya angiopathy encompass headaches, dizziness, cognitive impairments, seizures, and involuntary movements. When associated with an underlying systemic illness, including Down Syndrome, cranial radiation, neurofibromatosis type 1, or meningitis, the condition is termed Moyamoya syndrome; whereas when idiopathic and a genetic mutation are identified, it is referred to as Moyamoya disease. In this report, we present a case of the rare Moyamoya syndrome, which was attributed to syphilis and HIV infection and was identified during an investigation into the etiology of ischemic stroke in a young patient.

Spontaneous Pneumothorax, Pneumomediastinum, and Pneumopericardium in an HIV Patient With Tuberculosis: A Rare Trio.

A trio of spontaneous pneumomediastinum, pneumopericardium, and pneumothorax is a highly unusual presentation. The majority of reported cases are due to trauma, while the remaining cases are iatrogenic. Among infections, this trio has so far been reported in COVID-19 pneumonia and pneumocystis pneumonia in HIV-positive patients. There are case reports on pneumothorax and pneumomediastinum in tuberculosis, but the trio is not reported. Here, we present a case of a recently diagnosed HIV-positive patient with complaints of cough and shortness of breath whose initial workup was negative for Mycobacterium. The patient was, however, started on antitubercular drugs based on clinical radiological evidence. He developed spontaneous pneumothorax, pneumomediastinum, and pneumopericardium, and repeat bronchoalveolar lavage (BAL) came positive for Mycobacterium. The patient, however, could not be revived and succumbed to obstructive and septic shock.

A Literature Review on the Adherence to Screening Guidelines for Latent Tuberculosis Infection Among Persons Living With HIV.

Human immunodeficiency virus (HIV) infection increases the risk of reactivation of latent tuberculosis infection (LTBI). Although antiretroviral therapy decreases the progression of LTBI to tuberculosis disease (TBD), persons living with HIV (PLHIV) still have higher risk of TBD compared to the general population. LTBI screening is recommended for all newly diagnosed PLHIV to prevent TBD. However, several studies from low TBD incidence countries have reported sub-optimal implementation of these guidelines. This review aims to assess published studies on adherence to LTBI screening among PLHIV by identifying factors and determinants that affect the implementation of LTBI screening among PLHIV in low TBD incidence countries. Electronic databases were used to search for articles describing the adherence to LTBI screening guidelines. Fourteen studies were included in the final review. Ten studies assessed the frequency of PLHIV getting LTBI screening, and 4 studies assessed the compliance of health care providers in implementing the guidelines. PLHIV who were screened for LTBI ranged from 22.4% to 85%, of which 0.8% to 25.6% had positive results. Only 20% to 57.4% of surveyed physicians implemented the guidelines. Country of birth was an independent predictor of receiving LTBI screening. LTBI screening guidelines are inconsistently performed resulting in missed opportunities for TBD prevention. A comprehensive screening policy involving testing all PLHIV may be the best approach, rather than a targeted approach testing foreign-born individuals only. This will minimize missing domestic cases that can worsen disparity in HIV and tuberculosis infection among minority groups, including Asians, Native Hawaiians, and Pacific Islanders.

The Impact of Contemporary Antiretroviral Drugs on Atherosclerosis and Its Complications in People Living With HIV: A Systematic Review.

With the advent of modern antiretroviral therapy (ART), human immunodeficiency virus (HIV) infection has been modified into a chronic manageable condition, prolonging the lifespan of people living with HIV (PLHIV). This has resulted in an increased non-AIDS-related morbidity in the HIV-infected population. Our aim is to study the role of contemporary ART in tackling the risk of atherosclerosis and cardiovascular disease (CVD) in PLHIV. We searched through the databases of PubMed, PubMed Central, and Cochrane Library for pertinent articles using the medical subject headings (MeSH) "HIV infection", "Atherosclerosis", and "Antiretroviral agents". The articles published in the past five years were retrieved, screened for relevance, and assessed for quality before being included in the review. This review was performed following the PRISMA 2020 guidelines. The results indicate that the incidence of dyslipidemia with integrase strand transfer inhibitors (INSTIs) is greater than with non-nucleoside reverse transcriptase inhibitors (NNRTIs) and lesser than with protease inhibitors (PIs). INSTIs are indispensably associated with weight gain and obesity. High triglyceride (TG) and oxidized low-density lipoproteins to low-density lipoproteins (oxLDL/LDL) ratio levels and low high-density lipoprotein (HDL) levels are seen in patients taking PIs. A higher incidence of hypertension and metabolic syndrome (MetS) was noticed with INSTIs compared to NNRTIs. PI intake for >5 years increases the risk of subclinical atherosclerosis. Increased risk of myocardial infarction with INSTIs was observed in a study, while another study reported decreased risk. HIV infection independently increases the risk for atherosclerosis and CVD. Although contemporary ART decreases this enhanced risk, it inherently increases the risk for abnormal lipid profile, MetS, weight gain, and obesity. Further research into the risk of atherosclerosis and CVD with newer ART drugs is essential for decoding the underlying mechanisms and preventing adverse cardiac outcomes in PLHIV.

Post Cryptococcal Moyamoya Syndrome in Adult Human Immunodeficiency Virus Patient With Anterior and Posterior Circulation Involvement: Case Report.

Moyamoya disease (MMD) is a rare idiopathic progressive vaso-occlusive disease characterized by irreversible vascular occlusion and collateral development of distal internal carotid arteries. Initially perceived as an exclusive entity to the East Asian population, the disease is now being reported globally, affecting individuals of diverse ethnicities. We present a case of a 55-year-old African American male patient with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and a prior history of cryptococcal meningitis presenting to the emergency department with recurrent episodic headaches, which was refractory to routine medical therapy. Neuroimaging with computed tomography angiogram of the head and neck and magnetic resonance imaging of the brain led to the subsequent diagnosis of moyamoya syndrome (MMS). To our knowledge, MMS is uncommon in adult HIV/AIDS patients. It is crucial that clinicians are aware of the disease progression. For effective recognition and prevention of the condition, it is of utmost importance that clinicians possess a comprehensive understanding of the disease and its clinical manifestations.

Impact of Lung Disease on COVID-19 Health Outcomes in People Living With HIV.

Introduction COVID-19 most commonly causes pulmonary/lung infection, and these pulmonary diseases can complicate HIV infection. Underlying pulmonary diseases in people living with HIV (PLWH) could affect health outcomes if infected with COVID-19. Therefore, this study was designed to determine the impact of pulmonary diseases on the health outcomes of PLWH that were infected with COVID-19. Materials and methods We conducted a retrospective study to assess the impact of superimposed COVID-19 infection on pre-existing lung pathologies in patients living with human immunodeficiency virus (HIV) infection using data from the Minnesota Fairview network from January 1, 2020 to December 31, 2022. Ordinal logistic regressions were used to determine the effect of lung comorbidities on COVID-19 severity, COVID-19-specific mortality, and all-cause mortality, adjusting for patient age and gender.  Results Two hundred sixteen PLWH tested positive for COVID-19. 24.54% of these patients had one or more pulmonary diseases, including asthma, chronic obstructive pulmonary disease (COPD), and other lung diseases (interstitial lung diseases and pulmonary hypertension). The severity of COVID-19 outcomes was evaluated by the ranking of patients' medical records of testing positive, admitted to the hospital, being admitted to the ICU, and death. COVID-19-specific and all-cause mortality were evaluated separately. PLWH with underlying asthma or COPD was not associated with increased all-cause or COVID-19-specific mortality. Interstitial lung disease or pulmonary hypertension was significantly associated with poor health outcomes for COVID-19-specific mortality and all-cause mortality (Fisher's Exact p-value <0.001), with ICU admissions accounting for the most impact. Using the multivariate models, interstitial lung disease and pulmonary hypertension was significantly associated with an increased risk of more severe COVID-19 outcomes and COVID-19-specific mortality (OR=6.6153, CI=2.5944, 17.0795, p-value < 0.001). Interstitial lung disease and pulmonary hypertension were also significantly associated with an increased risk of more severe COVID-19 outcomes and all-cause mortality (OR=​​5.0885, CI=2.0590, 12.5542, p-value < 0.001). Conclusions To mitigate the poor outcomes associated with interstitial lung diseases and pulmonary hypertension in PLWH due to COVID-19, healthcare providers must educate their patients about safety measures against the COVID-19 vaccine. They can also encourage the COVID-19 vaccine uptake among their eligible patients.

Hemophagocytic Lymphohistiocytosis in a Patient with Hodgkin Lymphoma, HIV, and Epstein-Barr Virus.

Hemophagocytic lymphohistiocytosis (HLH) is an aggressive and life-threatening syndrome of excessive immune activation. It occurs in many underlying conditions and all age groups due to severe and uncontrolled inflammatory reactions, with the resultant overproduction of immune cells and cytokines. This leads to multi-organ damage (if not detected early and treated properly) with a mortality of more than 55%. We present a case of a 38-year-old male patient who presented with HLH with concurrent HIV/AIDS, and Epstein-Barr virus (EBV)-related Hodgkin lymphoma. We aim to emphasize the importance of considering HLH and cancer in patients with HIV/AIDS.

Efficiency of screening for human immunodeficiency virus infection in emergency departments: a systematic review and meta-analysis. / Eficiencia del cribado de VIH en urgencias: revisión sistemática y metanálisis.

OBJECTIVES: The rates of undiagnosed and late-diagnosed human immunodeficiency virus (HIV) infection are high. Screening for HIV infection in hospital emergency departments (EDs) could offer a way to increase the number of diagnoses. Our aim was to analyze whether universal hospital ED screening for HIV is efficient. MATERIAL AND METHODS: We followed the guidelines for Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). PubMed, the Cochrane Library, LILACS, Scopus, EMBASE, and the Web of Science were searched using the following terms: "HIV infections/epidemiology," "AIDS serodiagnosis," "emergency service, hospital," "prevalence," and "mass screening/methods." The searches were limited to a 5-year time frame (2016-2020); only publications in English or Spanish were collected. We included studies of universal HIV screening among hospital ED patients and evaluated them using the Quality Assessment Tool for Quantitative Studies. RESULTS: A total of 273 articles were identified. Twelve met the inclusion criteria. The studies analyzed 103 731 patient samples and yielded 652 new HIV diagnoses. A random effects model estimated an overall new-diagnosis prevalence of 0.60% (95% CI, 0.39%-0.84%). The heterogeneity statistic I2 was high, at 90.02% (P .001). Estimates of prevalence based on studies carried out in Europe, the United States, and Africa were, respectively, 0.48% (95% CI, 0.13%-1.03%), 0.54% (95% CI, 0.33%-0.40%), and 5.6% (95% CI, 3.37%-9.2%). The studies received quality ratings of moderate or strong. CONCLUSION: Although the reviewed studies applied various screening strategies to identify new HIV diagnoses, our findings support the conclusion that universal screening is efficient.

A case of human immunodeficiency virus (HIV) infection without increase in HIV RNA level: A rare observation during the modern antiretroviral therapy era.

It is known that some with human immunodeficiency virus (HIV)-positive patients can remain immunocompetent for long period, maintaining their CD4-positive T lymphocytes (CD4 cells) while suppressing HIV. However, this population became rarely seen recently since potent antiretroviral therapy (ART) became available worldwide, and the latest guidelines recommend initiating ART regardless of the status of immunity of the patients. Herein, we present a rather unusual case of HIV-1 infection, where the patient was hospitalized for 3 years and was accidentally found to have the infection, without increasing his HIV RNA level in serum although his CD4 cells were decreased.

Triumvirate Presentation and Treatment of Psoriasis in the Setting of HIV and Treponema pallidum Infection.

Psoriasis is an autoimmune condition in which the immune system attacks healthy skin cells, causing the accelerated formation of new skin characterized by scaly patches or plaques. These lesions are formed due to the formation of new skin underneath dead skin that has yet to be shed. Although the cause of psoriasis is not completely understood, it has been associated with infections that may trigger or exacerbate the condition. Syphilis, a highly infectious sexually transmitted disease, may trigger a psoriasis outbreak; because syphilis is known as "the great imitator", it can present as many other chronic dermatoses and therefore often makes it very difficult to diagnose. Here, we describe a case of a 17-year-old Vietnamese male from Dong Nai Province who was initially diagnosed with psoriasis and later diagnosed with syphilis and HIV infection upon further investigation and testing.

Continuum of Care UNAIDS Fast-Track Targets Evaluation of Patients Living with Human Immunodeficiency Virus Infection.

The current study evaluated the progress of continuum healthcare for patients living with human immunodeficiency virus (HIV) infection from Cluj County in two moments, 2016 and 2020, and compared the results to the Fast-Track targets (FTTs) proposed by the Joint United Nations Programme (UNAIDS) on HIV/AIDS. By the end of 2020, 368 out of 385 confirmed HIV-positive patients from Cluj County were under surveillance in our center, representing almost 95% of the patients living with HIV and knowing their diagnosis, compared to 87.9% in 2016. Nearly 97% of those in active follow-up from Cluj County were under antiretroviral therapy (ART) in 2020, compared to 89% in 2016. The number of virally suppressed patients from those under ART was almost 94% in 2020, compared to 82.7% in 2016, and the increase is observed regardless of the ART regime. A shift towards integrase strand transfer inhibitors, with a higher efficacy, fewer adverse effects, and fewer drug interactions, is observed, which could contribute to the decrease in HIV transmission.

Hemophagocytic Lymphohistiocytosis Following Skin and Soft Tissue Infection in a Patient With Human Immunodeficiency Virus.

Hemophagocytic lymphohistiocytosis (HLH) is a systemic inflammatory syndrome of inappropriate immune cell activation which can be rapidly fatal if not recognized and treated. Here we discuss a case of a 26-year-old male with HIV on antiretroviral therapy who presented with sepsis secondary to soft tissue infection and ultimately progressed to multi-organ dysfunction despite broad-spectrum antibiotics and an improvement in soft tissue infection. Continued fever and pancytopenia without an explanation found during additional infectious and rheumatologic testing eventually led to bone marrow biopsy and laboratory criteria consistent with HLH. Although pancytopenia is a common finding in patients with HIV, here it marked a more rapidly progressing and fatal disease, HLH. Here we highlight the difficulty in identifying and diagnosing this rare condition, including a discussion of the characteristics, outcomes, underlying etiologies, and treatment of HLH in patients with HIV.

Association of serum total bilirubin and plasma 8-OHdG in HIV/AIDS patients.

Oxidative stress is a major contributor in the pathogenesis of insulin resistance (IR) and DNA damage in HIV/AIDS patients. Bilirubin has been shown to have antioxidant effects. In this case-control study, 600 subjects were included. We determined serum total bilirubin and IR in all subjects. We measured 8-hydroxy-2-deoxyguanosine with 8-hydroxy-2-deoxyguanosine enzyme-linked immunosorbent assay kit. IR and oxidative DNA damage were significantly higher in HIV-positive patients with second-line antiretroviral therapy (ART) and first-line ART than ART-naive patients. However, average serum total bilirubin was higher in ART-naive patients than the HIV-positive patients with second-line ART and first-line ART. In a logistic regression analysis, serum total bilirubin was negatively associated with the IR [odds ratio (OR): 0.0127, 95% confidence interval (CI): 0.023-0.070, p = 0.0000] and DNA damage (OR: 0.525, 95% CI: 0.351-0.783, p = 0.0016). We found that prevalence of IR and DNA damage was less in ART-naive patients compared with ART first-line and ART second-line HIV-positive patients. Larger studies are warranted to determine the molecular mechanisms involved in the negative association of serum bilirubin and DNA damage in ART naive patients.

Association of Metabolic Syndrome and Oxidative DNA Damage in HIV/AIDS Patients.

HIV-infected adults may be likely to have metabolic syndrome (MS) at younger ages and in the absence of obesity compared with general population. In the present study, we determined prevalence of MS and its association with oxidative deoxy nucleic acid (DNA) damage in HIV-1 infected patients with different ART status. We used plasma level of the oxidized base, 8-hydroxy-2-deoxyguanosine (8-OHdG), as a biomarker of oxidative DNA damage. To measure plasma 8-OHdG we used 8-OHdG enzyme-linked, immunosorbent assay. The biomarkers of MS were insulin resistance, Cholesterol/HDL ratio, Waist circumference and Hypertension. MS and oxidative DNA damage were significantly higher in HIV-positive patients with second line ART and first line ART than ART-naive patients. In a logistic regression analysis, increased MS was positively associated with the increased DNA damage (OR: 29.68, 95%:13.47, CI: 65.40) P = 0.0001. ART plays a significant role in the development of MS and oxidative DNA damage in HIV-positive patients taking antiretroviral therapy. Awareness and knowledge of MS and DNA damage in HIV/AIDS patients may prove helpful to clinicians to manage non-AIDS diseases such as cardiovascular disease and cancer. To determine exact role of ART in induction of MS and DNA damage larger studies are warranted.

Protein carbonyl content: a novel biomarker for aging in HIV/AIDS patients

Abstract Background: The major complications of “treated” Human Immunodeficiency Virus (HIV) infection are cardiovascular disease, malignancy, renal disease, liver disease, bone disease, and perhaps neurological complications, which are phenomena of the normal aging process occurring at an earlier age in the HIV-infected population. The present study is aimed to explore protein carbonyl content as a biomarker for detecting oxidative DNA damage induced ART toxicity and/or accelerated aging in HIV/AIDS patients. Objective: To investigate the potential of carbonyl content as a biomarker for detecting oxidative Deoxyribonucleic acid (DNA) damage induced Antiretroviral Theraphy (ART) toxicity and/or accelerated aging in HIV/AIDS patients. Methods: In this case–control study a total 600 subjects were included. All subjects were randomly selected and grouped as HIV-negative (control group) (n = 300), HIV-infected ART naive (n = 100), HIV-infected on first line ART (n = 100), and HIV-infected on second line ART (n = 100). Seronegative control subjects were age- and sex-matched with the ART naive patients and the two other groups. Carbonyl protein was determined by the method described in Levine et al. DNA damage marker 8-OH-dG was determined using 8-hydroxy-2-deoxy Guanosine StressXpress ELA Kit by StressMarq Biosciences. Results: Protein carbonyl content levels and oxidative DNA damage were significantly higher (p < 0.05) in HIV-infected patients on second line ART and HIV-infected patients on first line ART than ART naive patients and controls. In a linear regression analysis, increased protein carbonyl content was positively associated with increased DNA damage (OR: 0.356; 95% CI: 0.287–0.426) p < 0.05. Conclusions: Carbonyl content may has a role as a biomarker for detecting oxidative DNA damage induced ART toxicity and/or accelerated aging in HIV/AIDS patients. Larger studies are warranted to elucidate the role of carbonyl content as a biomarker for premature aging in HIV/AIDS patients.

Antiretroviral Therapy for Prevention of Human Immunodeficiency Virus Infection.

Human immunodeficiency virus (HIV) infection is considered a chronic medical condition. Several new drugs are available, including fixed-dose combination tablets, that have greatly simplified combination antiretroviral therapy (ART) regimens to treat HIV, while increasing the life-expectancy of infected individuals. In the last decade, multiple well-regarded studies have established the benefits of using ART in high-risk, HIV-negative persons to prevent HIV acquisition. The primary care provider must not only understand commonly encountered issues pertaining to ART, such as toxicities and drug interactions, but also needs to be aware of using ART for HIV prevention.

Disrupted Homeostatic Cytokines Expression in Secondary Lymph Organs during HIV Infection.

Research has firmly established that infection by human immunodeficiency virus (HIV) leads to structural disruption in secondary lymph organs (SLOs) and that IL-7 expression by SLOs is downregulated in simian immunodeficiency virus (SIV)-infected rhesus macaques. However, the foregoing has not been demonstrated in HIV-infected patients. As well, SLO-produced chemokines and cytokines, other than IL-7, have not been tested. In this study, SLOs in HIV-infected patients exhibit decreased levels of lymphoid cytokines, such as IL-7 and C-C motif chemokine ligand 21 (CCL21), due to lower expression of lymphotoxin (LT)-ß. Previous research has shown that LT-ß is produced mainly by CD4⁺T cells in rhesus macaques, while our study found the same level of LT-ß expressed by CD4⁺T and CD8⁺T cells in humans. CD8⁺T cells substitute for depleted CD4⁺T cells LT-ß production. Only the total number of CD3⁺T cells can account for the majority of LT-ß in human SLOs. This study indicates a possible mechanism and a potential target for improvement of SLO function in HIV-infected patients, a novel adjuvant therapy for AIDS.

[Prevalence of undiagnosed human immunodeficiency virus infection in an emergency department and the characteristics of newly diagnosed patients]. / Prevalencia y características de los pacientes con infección por virus de la inmunodeficiencia humana (VIH) diagnosticados de novo en un servicio de urgencias.

OBJECTIVES: To estimate the prevalence of undiagnosed human immunodeficiency virus (HIV) infection detected by routine testing of patients seeking care in an emergency department and to describe the characteristics associated with new HIV-infection diagnosis. MATERIAL AND METHODS: Walk-in patients between the ages of 15 and 75 years who required a blood test were included. Routine fourth-generation enzyme-linked immunoassays were performed to detect HIV infection in all samples extracted. Patients with positive results were referred to the infectious diseases department for monitoring and treatment. RESULTS: Blood samples for 1722 patients were analyzed. Twenty-one patients (1.2%) refused to allow their samples to be tested; 19 more samples (1.1%) could not be tested. The prevalence of undiagnosed HIV infection among the remaining 1682 remaining patients was 0.6% (95% CI, 0.23%-0.96%). The prevalence tended to be nonsignificantly higher among patients born outside Spain (0.97% [95% CI, 0.3%-2.20%]) and in 36-50-year-olds (1.46% [95% CI, 0.4%-2.5%]). Characteristics associated with undiagnosed HIV infection were male sex (odds ratio [OR], 5.78 [95% CI, 1.0-31.4]), presenting with a chief complaint that suggested infection (OR, 8.14 [95% CI, 1.6-41.4]), and a history of hepatitis (OR, 5.53 [95% CI, 1.1-27.7]). CONCLUSION: The prevalence of undiagnosed HIV infection in our emergency department was high at 0.6%. The rate of patient acceptance of routine HIV testing was high. Strategies that target improving the detection of undiagnosed HIV infection are advisable.

OBJETIVO: Estimar la prevalencia de la infección por el virus de la inmunodeficiencia humana (VIH) no diagnosticada entre la población que acude al servicio de urgencias hospitalario (SUH) mediante la realización rutinaria del test para VIH, y describir los factores asociados al diagnóstico. METODO: Estudio descriptivo transversal que incluyó a los pacientes entre 15 y 75 años valorados en la zona de pacientes ambulantes del SUH y a los que se les realizó una analítica sanguínea por su motivo de consulta, en la que se obtuvo una muestra para realizar la prueba del VIH de manera rutinaria mediante test de enzimoinmunoanálisis (EIA) de 4ª generación. Los pacientes con resultado positivo fueron remitidos al servicio de infecciosas para seguimiento y tratamiento. RESULTADOS: Se obtuvieron muestras de sangre de 1.722 pacientes. De estos, 21 (1,2%) rechazaron la realización de la serología y 19 (1,1%) no fueron finalmente analizados. La prevalencia de infección VIH no diagnosticada entre los 1.682 pacientes analizados fue del 0,6% [IC 95%: 0,23-0,96%]. Fue, sin significación estadística, mayor en los pacientes nacidos en otros países 0,97% [IC 95%: 0,3-2,20] y en los pacientes de 36 a 50 años 1,46% [IC 95%: 0,4-2,5]. Los factores que se asociaron con infección no conocida por VIH fueron ser hombre [OR: 5,78 (IC 95%: 1,0-31,4)], tener un motivo de consulta sugerente de infección [OR: 8,14 (IC 95%: 1,6-41,4)] y tener antecedentes de hepatitis [OR: 5,53 (IC 95%: 1,1-27,7)]. CONCLUSIONES: Hubo una alta prevalencia (0,6%) de infección por VIH no diagnosticada entre los pacientes atendidos en urgencias, los cuales mostraron una alta aceptación para realizar una serología VIH de manera rutinaria y universal. Estos resultados aconsejan mejorar las estrategias de detección de infección oculta por VIH.
