Progressive multifocal encephalopathy (PML) is a rare but often fatal infectious brain disease caused by the reactivation of John Cunningham polyomavirus. Reactivation occurs in immunocompromised individuals with AIDS and leukemia, on chemotherapy or being treated with immunosuppressant drugs (e.g. monoclonal antibodies). Cases of PML have been described in patients treated with natalizumab, efalizumab and rituximab used, respectively, for the treatment of (1) multiple sclerosis, (2) psoriasis and (3) haematological malignancies or systemic autoimmune diseases (rheumatoid arthritis and systemic lupus erythematosus). The authors describe an unusual case of acute brainstem and cerebellar PML following chemotherapy for chronic lymphatic leukemia diagnosed 4 years before the onset of PML in a 75-year-old man. The patient was treated with high dose chemotherapy and rituximab with complete response. The onset of symptoms of PML was very rapid and occurred after more than two years from last rituximab infusion;patient had a sudden neurological deterioration, with rapid progression to death in about a month from the onset of symptoms. Lesions were localized in the cerebellum, brainstem and such pattern has been reported in very few cases in the literature.

Epigenetic modifications include DNA methylation, his-tone modifications, and micro RNA. Gene alterations have been found to be associated with cardiovascular diseases, and epigenetic mechanisms are continuously being studied to find new useful strategies for the clinical management of afflicted patients. Numerous cardiovascular disorders are characterized by the abnormal methylation of Cp G islands and so specific drugs that could inhibit DNA methyltransferase directly or by reducing its gene expression(e.g., hydralazine and procainamide) are currently under investigation. The anti-proliferative and anti-inflammatory properties of histone deacetylase inhibitors and their cardio-protective effects have been confirmed in preclinical studies. Furthermore, the regulation of the expression of micro RNA targets through pharmacological tools is still under development. Indeed, large controlled trials are required to establish whether current possible candidate antisense micro RNAs could offer better therapeutic benefits in clinical practice. Here, we updated therapeutic properties, side effects, and feasibility of eme-rging epigenetic-based strategies in cardiovascular diseases by highlighting specific problematic issues that still affect the development of large scale novel therapeutic protocols.

Severe Acute Respiratory Syndrome Coronavirus(SARS-CoV)-2 infection induces an exacerbated inflammation driven by innate immunity *** cells(DCs)play a key role in the defense against viral infections,for instance plasmacytoid DCs(pDCs),have the capacity to produce vast amounts of interferon-alpha(IFN-α).In COVID-19 there is a deficit in DC numbers and IFN-αproduction,which has been associated with disease *** this work,we described that in addition to the DC deficiency,several DC activation and homing markers were altered in acute COVID-19 patients,which were associated with multiple inflammatory ***,previously hospitalized and nonhospitalized patients remained with decreased numbers of CD1c+myeloid DCs and pDCs seven months after SARS-CoV-2 ***,the expression of DC markers such as CD86 and CD4 were only restored in previously nonhospitalized patients,while no restoration of integrinβ7 and indoleamine 2,3-dyoxigenase(IDO)levels were *** findings contribute to a better understanding of the immunological sequelae of COVID-19.
