Neurologic Manifestation HIV AIDS

BACKGROUND The iceberg phenomenon (in which the most of a problem is invisible) of people living with HIV/AIDS, particularly those with unknown HIV status, has been epidemiologically challenging. Central nervous system (CNS) opportunistic infections in patients with HIV/AIDS are one of the leading causes of morbidity and mortality in people living with HIV/AIDS. There are currently limited data on the immunogenicity, safety, and efficacy of COVID-19 vaccines in people living with HIV/AIDS with its associated opportunistic CNS infections as well as those without antiretroviral treatment...

Human immunodeficiency virus (HIV)-associated disease is known for its protean manifestations. However, many of the characteristic findings on physical examination are not associated with HIV infection per se but the numerous opportunistic infections (OIs) that are common in patients with advanced HIV disease. Common findings of acute HIV infection include fever, adenopathy, rash, and oral ulcers. Chronic HIV infection is associated with skin, rheumatologic, and neurologic manifestations. OIs also cause skin, oropharyngeal, ocular, and neurologic manifestations...

Perilesional edema, associated or not with neurological manifestations, is a well-characterized finding in cases of calcified neurocysticercosis. There are no previous reports of HIV-related calcified toxoplasmosis that mimics this presentation of neurocysticercosis. We report on five patients, four of them with new-onset neurological manifestations, who showed brain calcifications associated with perilesional edema. All cases had a history of HIV-related toxoplasmosis and current virological and immunological control of HIV infection...

Toxoplasmosis encephalopathy (TE) is a kind of encephalopathy parasitic disease caused by Toxoplasma gondii . It is the most common opportunistic for central system infection in patients with acquired immunodeficiency syndrome (AIDS) or human immunodeficiency virus. Without early diagnosis and proper treatment, this opportunistic infection can be life-threatening. The common clinical manifestations of the disease include altered mental state, epilepsy, cranial nerve damage, paresthesia, cerebellar signs, meningitis, motor disorders, and neuropsychiatry...

INTRODUCTION: Human Immunodeficiency virus (HIV) is a virus that causes several diseases by attacking the human immune system. It is transmitted by contact with certain bodily fluids of an infected person, most commonly during unprotected sex, through sharing needles, or from mother to baby during pregnancy, birth or breastfeeding. The central nervous system is not spared from this virus, as HIV has been shown to induce several neurological disorders. However most neurological pathologies (such as dementia, infections, meningitis, and neuropathy) rarely show until late stages, in this case, after the patients develop acquired immunodeficiency syndrome (AIDS)...

So far, only two retroviruses, human immunodeficiency virus (HIV) (type 1 and 2) and human T-cell lymphotropic virus type 1 (HTLV-1), have been recognized as pathogenic for humans. Both viruses mainly infect CD4+ T lymphocytes. HIV replication induces the apoptosis of CD4 lymphocytes, leading to the development of acquired immunodeficiency syndrome (AIDS). After a long clinical latency period, HTLV-1 can transform lymphocytes, with subsequent uncontrolled proliferation and the manifestation of a disease called adult T-cell leukemia (ATLL)...

An isolated cranial nerve VI palsy is a rare initial manifestation of undiagnosed neurosyphilis. A 33-year-old male presented with a one month history of progressive headache and diplopia. Neurologic examination only revealed an isolated abducens palsy on the left. Cranial imaging was unremarkable. Examination of his cerebrospinal fluid revealed lymphocytic predominant leukocytosis and elevated protein. Microbiologic work-up were all negative. Further work-up revealed the patient to be serum Rapid Plasma Reagin and Enzyme Immunoassay reactive...

INTRODUCTION: Cranial nerve (CN) VI palsy is a common complaint seen in the emergency department (ED) and has a wide range of causes. Bilateral CN VI palsies are uncommon and appear to be associated with more severe complications. CASE REPORT: A 29-year-old male presented to the ED from an ophthalmology office for diplopia, headache, and strabismus. He was found to have bilateral CN VI palsies and new-onset seizure in the ED. A lumbar puncture revealed cryptococcal meningitis...

Background: The aim of this study was to evaluate the frequency, spectrum, in-hospital mortality rate, and factors associated with death in people living with HIV/AIDS (PLWHA) presenting with neurological diseases from a middle-income country, as well as estimate its one-year global death rate. Methods: This prospective observational cohort study was conducted at a Brazilian tertiary health center between January and July 2017. HIV-infected patients above 18 years of age who were admitted due to neurological complaints were consecutively included...

BACKGROUND: Defining socio-demographic factors, clinical presentations and underlying diseases associated with COVID-19 severity could be helpful in its management. This study aimed to further clarify the determinants and clinical risk factors of the disease severity in patients infected with COVID-19. METHODS: A multi-centre descriptive study on all patients who have been diagnosed with COVID-19 in the province of Tehran from March 2020 up to Dec 2020 was conducted...

Among all the viral infections, acquired immunodeficiency syndrome (AIDS) is considered as one of the most morbid infections caused by the human immunodeficiency virus (HIV). The prime reason for the pathogenesis is the profound immunosuppression that leads to lethal opportunistic infections (OI), neurological disorders, unexpected malignancies and pathologies of the orofacial region. Patients with OI whose HIV status is unknown have shown a mortality rate higher than those with known HIV status. Among HIV-associated infections, orofacial lesions contribute a major proportion of the OI attributed to the plethora of micro-organisms present in the oral cavity...

Individuals with HIV may present to the emergency department with HIV-related or HIV-unrelated conditions, toxicity associated with antiretroviral therapy or primary HIV infection (seroconversion). In individuals with HIV infection, central nervous system toxoplasmosis occurs from reactivation of disease, especially when the CD4+ count is <100 cells/μL, whereas in those taking immunosuppressive therapy, this can be either due to newly acquired or reactivated latent infection. It is a rare occurrence in immune-competent patients...

Toxoplasma gondii is a known cause of encephalitis in human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients. Toxoplasma pneumonitis is a manifestation of extracerebral toxoplasmosis and can be clinically indistinguishable from other opportunistic infections including Pneumocystis jirovecii pneumonia (PJP) and miliary tuberculosis. In this case report, Toxoplasma pneumonitis and disseminated toxoplasmosis was diagnosed using next-generation sequencing (NGS) and polymerase chain reaction (PCR) assessment...

Objectives  To determine the neurological manifestations in AIDS patients with a recent diagnosis. Materials and methods A descriptive, retrospective study was carried out on 82 patients, admitted to the University Hospital in Curitiba for a period of 30 months, with positive serology for HIV, using the enzyme-linked immunosorbent assay (ELISA) method for diagnosis and confirmation. Results Of the 82 patients studied, 28 (34.1%) presented neurological manifestations; 16 were male (57.14%) and 12 female (42...

BACKGROUND: Patients with retroviral disease are prone to opportunistic infections (OIs) of the central nervous system which cause significant mortality and morbidity. Cryptococcosis, tuberculosis, and toxoplasma are the most commonneuroinfections occurring at all stages of the disease. OBJECTIVE: This study was undertaken to evaluate the clinical pattern of OIs and in-hospital mortality in patients with acquired immunodeficiency syndrome (AIDS). MATERIALS AND METHODS: This retrospective analysis was conducted in a teaching hospital from 2001 to2014...

BACKGROUND: Meningitis is a leading cause of death among patients living with HIV. There is no adequate tracking of the disease occurrence, distribution and etiologic agents among this risk group in Egypt, although the pattern could differ from that of the general population. OBJECTIVES: We aimed to describe the spatio-temporal distribution of meningitis in HIV patients in a region of Northern Egypt over 18 years (2000-2018). METHODS: We conducted a retrospective study of 352 adult HIV patients admitted to a tertiary care fever hospital with neurological manifestations suggesting meningitis...

Efavirenz (EFV) is a well-known, effective anti-retroviral drug long used in first-line treatment for children and adults with HIV and HIV/AIDS. Due to its narrow window of effective concentrations, between 1 and 4 μg/mL, and neurological side effects at supratherapeutic levels, several investigations into the pharmacokinetics of the drug and its genetic underpinnings have been carried out, primarily with adult samples. A number of studies, however, have examined the genetic influences on the metabolism of EFV in children...

Taenia solium cysticercosis and taeniasis (TSCT), caused by the tapeworm T. solium, is a foodborne and zoonotic disease classified since 2010 by WHO as a neglected tropical isease. It causes considerable impact on health and economy and is one of the leading causes of acquired epilepsy in most endemic countries of Latin America, Sub-Saharan Africa, and Asia. There is some evidence that the prevalence of TSCT in high-income countries has recently increased, mainly due to immigration from endemic areas. In regions endemic for TSCT, human cysticercosis can manifest clinically as neurocysticercosis (NCC), resulting in epileptic seizures and severe progressive headaches, amongst other neurological signs and/or symptoms...

Cerebral toxoplasmosis is one of the neurological infections with high morbidity and mortality in patients with AIDS, so the accurate method for diagnosis of cerebral toxoplasmosis seems necessary. In this study, nested PCR assay using B1 gene was evaluated in diagnosis of toxoplasmosis in serum and peripheral blood mononuclear cell (PBMC) among HIV/AIDS patients. One hundred eight blood samples from HIV/AIDS patients, including four patients with cerebral toxoplasmosis and 104 HIV/AIDS patients without cerebral toxoplasmosis were evaluated for the Toxoplasma gondii antibodies using Enzyme Linked immunosorbent Assay...
