Moyamoya syndrome in a pediatric patient with congenital human immunodeficiency virus type 1 infection resulting in intracranial hemorrhage.

J Infect Chemother 2018 Mar 11;24(3):220-223. Epub 2017 Nov 11.

National Center for Global Health and Medicine, Department of Pediatrics, Japan.

In the era of Antiretroviral Therapy (ART) in which human immunodeficiency virus type 1 (HIV-1) infection affected children can expect a better prognosis, the importance of careful follow up of pediatric HIV-1 cases for neurological complications has been growing. We present a case of hemorrhagic Moyamoya syndrome in a child with congenital HIV-1 infection. A 10-year-old girl was referred to our hospital for the treatment of Pneumocystis Jirovecii Pneumonia (PCP: Pneumocystis pneumonia). Read More

Neurologic Complications in Treated HIV-1 Infection.

Curr Neurol Neurosci Rep 2016 07;16(7):62

Departments of Neurology and Medicine (Infectious Diseases), University of California, San Francisco, CA, USA.

Effective combination antiretroviral therapy has transformed HIV infection into a chronic disease, with HIV-infected individuals living longer and reaching older age. Neurological disease remains common in treated HIV, however, due in part to ongoing inflammation and immune activation that persist in chronic infection. In this review, we highlight recent developments in our understanding of several clinically relevant neurologic complications that can occur in HIV infection despite treatment, including HIV-associated neurocognitive disorders, symptomatic CSF escape, cerebrovascular disease, and peripheral neuropathy.

Cytomegalovirus coinfection is associated with an increased risk of severe non-AIDS-defining events in a large cohort of HIV-infected patients.

J Infect Dis 2015 Jan 31;211(2):178-86. Epub 2014 Jul 31.

San Paolo Hospital.

Background: Chronic cytomegalovirus (CMV) infection has been associated with immunosenescence and immunoactivation in the general population. In human immunodeficiency virus type 1 (HIV-1)-infected people, CMV coinfection, in addition to residual HIV replication and microbial translocation, has been proposed as a key factor in sustaining immune activation, even in individuals with a controlled HIV load.

Methods: Patients from the ICONA Study with at least 1 CMV immunoglobulin G (IgG) test available without active CMV disease were included in the analysis. Read More

Characterization of platelet-monocyte complexes in HIV-1-infected individuals: possible role in HIV-associated neuroinflammation.

J Immunol 2014 May 11;192(10):4674-84. Epub 2014 Apr 11.

Department of Microbiology and Immunology, University of Rochester Medical Center, Rochester, NY 14642.

HIV-1-associated neuroinflammation persists even with effective combined antiretroviral therapy, and it is associated with the presence of activated monocytes/macrophages within the CNS. To infiltrate the CNS, monocytes transmigrate across the selectively permeable blood-brain barrier, which is compromised during HIV-1 infection. Interestingly, platelet-derived excess soluble CD40 ligand found in the plasma and cerebrospinal fluid of HIV-1-infected individuals with cognitive impairment has previously been implicated in increased blood-brain barrier permeability.

Immuno-virological discordance and the risk of non-AIDS and AIDS events in a large observational cohort of HIV-patients in Europe.

PLoS One 2014 31;9(1):e87160. Epub 2014 Jan 31.

Department of Medicine I, Infectious Diseases Unit, University Medical Center Hamburg-Eppendorf, Hamburg, Germany.

Background: The impact of immunosuppression despite virological suppression (immuno-virological discordance, ID) on the risk of developing fatal and non-fatal AIDS/non-AIDS events is unclear and remains to be elucidated.

Methods: Patients in EuroSIDA starting at least 1 new antiretroviral drug with CD4<350 cells/µl and viral load (VL)>500 copies/mL were followed-up from the first day of VL< = 50 copies/ml until a new fatal/non-fatal non-AIDS/AIDS event. Considered non-AIDS events included non-AIDS malignancies, pancreatitis, severe liver disease with hepatic encephalopathy (>grade 3), cardio- and cerebrovascular events, and end-stage renal disease.

Transient hypercapnia reveals an underlying cerebrovascular pathology in a murine model for HIV-1 associated neuroinflammation: role of NO-cGMP signaling and normalization by inhibition of cyclic nucleotide phosphodiesterase-5.

J Neuroinflammation 2012 Nov 20;9:253. Epub 2012 Nov 20.

Department of Microbiology and Immunology, University of Rochester Medical Center, 601 Elmwood Avenue, Box 672, Rochester, NY 14642, USA.

Background: Cerebral blood flow (CBF) is known to be dysregulated in persons with human immunodeficiency virus 1 (HIV-1), for uncertain reasons. This is an important issue because impaired vasoreactivity has been associated with increased risk of ischemic stroke, elevated overall cardiovascular risk and cognitive impairment.

Methods: To test whether dysregulation of CBF might be due to virally-induced neuroinflammation, we used a well-defined animal model (GFAP-driven, doxycycline-inducible HIV-1 Tat transgenic (Tat-tg) mice). Read More

Cerebrovascular ischemic events in HIV-1-infected patients receiving highly active antiretroviral therapy: incidence and risk factors.

Cerebrovasc Dis 2009 24;27(6):559-63. Epub 2009 Apr 24.

Stroke Unit, Neurology Service, Hospital Ramón y Cajal, Madrid, Spain.

Background: Stroke risk is increased in AIDS patients, and highly active antiretroviral therapy (HAART) may accelerate atherosclerosis, but little is known about the incidence and risk factors for ischemic stroke in patients under HAART. We have studied the incidence, types of stroke and possible risk factors for cerebrovascular ischemic events in a large cohort of HIV-1-infected patients treated with HAART.

Methods: We conducted a retrospective review of ischemic strokes and transient ischemic attacks occurring in a cohort of HIV-1-infected patients treated with HAART from 1996 to 2008. Read More

HIV-associated vascular diseases: structural and functional changes, clinical implications.

Int J Cardiol 2009 Apr 7;133(3):293-306. Epub 2009 Jan 7.

AP-HP, Hôpital René Muret, Policlinique médicale, Université Paris, Sevran, France.

After more than two decades of AIDS epidemic, the spectrum of HIV-associated vascular diseases has mainly evolved from infectious and inflammatory vasculitides to premature atherosclerosis, its related contributing conditions (metabolic syndrome, dyslipidemia, insulin resistance syndrome) and complications (acute coronary and cerebrovascular syndromes). Today, as the AIDS epidemic further progresses worldwide and as the life expectancy of HIV-infected patients treated with effective antiviral regimens has dramatically increased, more than 10% of patients experience cardiovascular manifestations. The complex interplay between viral infection, inflammatory and cytokines pathways, protease inhibitors-induced hyperlipidemia and direct effects on endothelial cells has not, by far, been integrated in a single comprehensive pathogenesis network.

QJM 2004 Jul;97(7):413-21

Division of Radiology, Department of Radiation Sciences, School of Clinical Medicine, Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, South Africa.

Background: HIV-associated focal brain lesions (HFBL) are caused by opportunistic infections, neoplasms, or cerebrovascular diseases. In developed countries, toxoplasma encephalitis (TE) is the most frequent cause, followed by primary CNS lymphoma (PCNSL). Guidelines based on these causes however are poorly suited to developing countries, where treatable infections predominate as causes of HFBL. Read More

Cognitive impairment in older HIV-1-seropositive individuals: prevalence and potential mechanisms.

AIDS 2004 Jan;18 Suppl 1:S79-86

University of Hawaii, NeuroAIDS Specialized Neuroscience Research Program, John A. Burns School of Medicine, Honolulu, Hawaii 96816, USA.

Individuals over 50 years of age comprise 11% of AIDS cases reported to the Centers for Disease Control and Prevention. A higher prevalence of AIDS in older individuals has been reported in certain states including Hawaii (20%) and Florida (13%). Although life expectancy in individuals with AIDS has increased with advances in antiretroviral therapy, it is likely that there are health consequences both of long-term infection and chronic antiretroviral therapy.

[Aids: is it a risk factor in cerebrovascular disease?].

Rev Neurol 2002 Nov 1-15;35(9):808-11

Policlinico Docente "Heroes del Moncada". Municipio de Salud Plaza, La Habana, Cuba.

Introduction: Cerebrovascular disease (CVD) has become an important health problem throughout the world. It is generally one the main causes of morbidity and mortality in the world, especially in developed countries. In these countries the frequency with which it appears is linked with the progress reached in the organisation of the public health system and the higher economic and social standards of their populations, which have given rise to prolonged life expectancy and a greater number of elderly people.

Aging and neuro-AIDS conditions and the changing spectrum of HIV-1-associated morbidity and mortality.

J Clin Epidemiol 2001 Dec;54 Suppl 1:S35-43

Department of Psychiatry and Behavioral Sciences, University of Miami School of Medicine, 1400 NW 10th Ave, #803-A, Miami, FL 33136, USA.

Older individuals (>50 years of age) now comprise over 11% of patients with AIDS in the United States. This percentage is expected to continue to grow, due both to the improved longevity of patients prescribed highly active antiretroviral therapy (HAART) and to new infections among older individuals. This review focuses on the neuropsychiatric and neurological conditions that are most likely to be affected by advancing age-HIV-1-associated cognitive-motor disorder, peripheral neuropathy, progressive multifocal leukoencephalopathy, primary CNS lymphoma, and risk for cerebrovascular accident.

Neurological and developmental problems in pediatric HIV infection.

Authors:
M Mintz

J Nutr 1996 10;126(10 Suppl):2663S-2673S

Cooper Hospital/University Medical Center, Camden, New Jersey 08103, USA.

Human immunodeficiency virus type-1 (HIV-1)-associated neurologic disease, known as "HIV-1-associated progressive encephalopathy" (PE), is a common concomitant in the progression towards AIDS. PE, characterized by a triad of symptoms including impaired brain growth, progressive motor dysfunction, and loss or plateau of developmental milestones, is believed to result from both direct and indirect effects of HIV-1 infection on the central nervous system (CNS). Consequent to the hallmark systemic immune deficiency of HIV infection, the CNS becomes susceptible to opportunistic infections which add further morbidity and mortality, and may contribute either directly or indirectly to neurologic symptoms which can often mimic PE.
