Progressive multifocal leukoencephalopathy in non-HIV patient

Please help leucoencefalpoatia this section by adding citations to reliable sources. Restoration of the adaptive immune response is crucial in controlling JCV replication and stabilizing disease.

D ICD – However, other causes of immunosuppression such as organ transplantation, chemotherapy, immunotherapies with monoclonal antibodies, autoimmune diseases and lymphoma, may also be associated with PML.

How to cite this article.

T1-weighted image post-contrast reveals cortical-subcortical hypointensity in left temporal lobe, without enhancement white arrow. However, the widespread use of HIV antiretroviral drugs and new selective immunomodulatory and immunosuppressive medications, such as Rituximab and Natalizumab, had recently modified the epidemiology, clinical presentation and prognosis of PML 3.

Progressive multifocal leukoencephalopathy – Wikipedia

PML occurs almost exclusively in patients with severe immune deficiencymost commonly multifoccal patients with acquired immune deficiency syndrome AIDSbut people on chronic immunosuppressive medications including chemotherapy are also at increased risk of PML, such as patients with transplants, Hodgkin’s lymphomamultiple sclerosispsoriasisand other autoimmune diseases.

Insomnia Hypersomnia Sleep apnea Obstructive Congenital central hypoventilation syndrome Narcolepsy Cataplexy Kleine—Levin Circadian rhythm sleep disorder Advanced sleep phase disorder Delayed sleep phase disorder Nonhour sleep—wake disorder Jet lag. In general, demyelination occurs in a multifocal and asymmetric manner.


Since restoration of the cellular immune response against JCV is the best predictor of survival in PML 8the introduction of combined antiretroviral drugs led to a significant improvement in mortality.

Infectious elucoencefalopatia — viral systemic diseases A80—B34— The most prominent symptoms are “clumsiness, progressive weakness, and visual, speech, and sometimes personality changes”.

PML is a demyelinating diseasein which the myelin sheath covering the axons of nerve cells is gradually destroyed, impairing the transmission of nerve impulses. The breakdown of myelin is commensurate with the degree of immunocompromise. Progressive multifocal leukoencephalopathy PML is a rare and often fatal viral umltifocal characterized by progressive damage -pathy or inflammation of the white matter leuko- of the brain -encephalo- at multiple locations multifocal.

Migraine Familial hemiplegic Cluster Tension. Mirtazapine, an antidepressant that acts inhibiting this receptor has been used in treatment of PML.

Clin Microbiol Rev ; There are reports of JCV isolation in the CSF of immunocompetent and immunosuppressed patients with a meningeal syndrome and no focal symptoms The presence of seizures, vertigo, headache and aphasia is less frequent.

Incidence of progressive multifkcal leukoencephalopathy in patients without HIV. Two case reports of using interleukin-2 successfully have been published.

Rarely, JCV has been associated with meningitis and encephalitis 28 On the other hand, immune surveillance performed by these cells against JCV and other virus may be impaired resulting in the development of PML.


Archived from the original on 4 January Therefore, treatment aims at reversing the immune deficiency to slow or stop the disease progress.

PML can still occur in people on immunosuppressive therapy, such as efalizumab, [7] belatacept, [8] and various transplant drugs, which are meant to weaken the immune system. JC virus meningitis in a patient with systemic lupus erythematosus. It usually follows the rapid restoration of the immune function and is often self-limited, but it can be fatal or associated with permanent sequelae.

Treatment There are no specific antivirals drugs against JCV.
