Neurotuberculosis immune reconstitution inflammatory syndrome in the setting of HIV infection: A case report and review of literature.

Indian J Radiol Imaging 2016 Oct-Dec;26(4):446-450

Department of Radiodiagnosis, Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Pondicherry, India.

Immune reconstitution inflammatory syndrome (IRIS) is an exaggerated immune response which can occur with various coinfections in human immunodeficiency virus (HIV) infected patients, of which the most commonly implicated in central nervous system (CNS)-IRIS are progressive multifocal leukoencephalopathy (PML), cryptococcosis, and tuberculosis (TB). TB-IRIS is a known complication of pulmonary TB or TB lymphadenitis coinfection in HIV infected patients who are on antituberculosis treatment (ATT) after the initiation of antiretroviral therapy (ART). However, development of IRIS in extrapulmonary TB such as CNS TB is very rare. Read More

[Dementia in Patients with Central Nervous System Mycosis].

Brain Nerve 2016 Apr;68(4):329-39

Division of Neurology, Department of Medicine, Nihon University School of Medicine.

Central nervous system (CNS) mycosis is a potentially life-threatening but treatable neurological emergency. CNS mycoses progress slowly and are sometimes difficult to distinguish from dementia. Though most patients with CNS mycosis have an underlying disease, such as human immunodeficiency virus (HIV) infection, cancer, diabetes mellitus, and/or use of immunosuppressants, cryptococcosis can occur in non-immunosuppressed persons.

Spectrum of imaging appearances of intracranial cryptococcal infection in HIV/AIDS patients in the anti-retroviral therapy era.

Clin Radiol 2016 Jan 10;71(1):9-17. Epub 2015 Nov 10.

Department of Neuroradiology, Imaging Department, Royal London Hospital, Barts Health NHS Trust, Whitechapel, London E1 1BB, UK.

Cryptococcus neoformans infection is the most common fungal infection of the central nervous system (CNS) in advanced human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) patients, but remains a relatively uncommon CNS infection in both the immunocompromised and immunocompetent patient population, rendering it a somewhat elusive and frequently overlooked diagnosis. The morbidity and mortality associated with CNS cryptococcal infection can be significantly reduced by early recognition of the imaging appearances by the radiologist in order to focus and expedite clinical management and treatment. The emergence and evolution of anti-retroviral therapy have also impacted significantly on the imaging appearances, morbidity, and mortality of this neuro-infection. Read More

Paradoxical Immune Responses in Non-HIV Cryptococcal Meningitis.

PLoS Pathog 2015 May 28;11(5):e1004884. Epub 2015 May 28.

Laboratory of Clinical Infectious Diseases, NIAID, NIH, Bethesda, Maryland, United States of America.

The fungus Cryptococcus is a major cause of meningoencephalitis in HIV-infected as well as HIV-uninfected individuals with mortalities in developed countries of 20% and 30%, respectively. In HIV-related disease, defects in T-cell immunity are paramount, whereas there is little understanding of mechanisms of susceptibility in non-HIV related disease, especially that occurring in previously healthy adults. The present description is the first detailed immunological study of non-HIV-infected patients including those with severe central nervous system (s-CNS) disease to 1) identify mechanisms of susceptibility as well as 2) understand mechanisms underlying severe disease.

A retrospective study of contributing factors for prognosis and survival length of cryptococcal meningoencephalitis in Southern part of China (1998-2013).

BMC Infect Dis 2015 Feb 19;15:77. Epub 2015 Feb 19.

Department of Neurology, Nanfang Hospital, Southern Medical University, No.1838 North Guangzhou Avenue, Guangzhou City, Guangdong Province, People's republic of China.

Background: Cryptococcal meningoencephalitis (CM) is the most common opportunistic infection of the central nervous system (CNS). Despite this observation, there have only been a few studies analyzing clinical characteristics as well as cerebrospinal fluid (CSF), electroencephalograph (EEG), and magnetic resonance imaging (MRI) features in CM patients of all ages.

Methods: We reviewed the medical records of all patients diagnosed with cryptococcal meningoencephalitis from 1998 to 2013 in the Nanfang Hospital in China and gathered data on the underlying diseases, bird exposure history, and clinical features, including those from CSF, EEG and MRI. Read More

Acute longitudinal myelitis following Cryptococcus laurentii pneumonia in a patient with systemic lupus erythematosus.

Lupus 2015 Jan 8;24(1):94-7. Epub 2014 Oct 8.

Dipartimento di Medicina Interna e Specialità Mediche - Reumatologia; Sapienza Università di Roma, Rome, Italy.

Central nervous system (CNS) involvement in systemic lupus erythematosus (SLE) is reported in about 50% of patients. Among the neuropsychiatric features of SLE, myelopathy, including acute transverse myelitis (ATM) or acute longitudinal myelitis (ALM), represents an uncommon event. A possible vascular aetiology of SLE myelopathies has been hypothesized and it seems to be much more associated to SLE-associated antiphospholipid syndrome (APS). Read More
