Genetic predisposition to autoimmune hepatitis (AIH) in adults is associatedwith possession of human leukocyte antigen (HLA) class I (A*01,B*08) and class II (DRB1*03,-04, -07, or-13) alleles,depending on geographic region. Juvenile autoimmune liver disease (AILD) comprises AIH-1, AIH-2, and autoimmune sclerosing cholangitis (ASC), which are phenotypically different from their adult counterparts. We aimed to define the relationship between HLA profile and disease course, severity, and outcome in juvenile AILD.

We studied 236 children of European ancestry (152 female [64%], median age 11.15 years, range 0.8-17), including 100 with AIH-1, 59 with AIH-2, and 77 with ASC. The follow-up period was from 1977 to June 2019 (median 14.5 years). Class I and II HLA genotyping was performed using PCR/sequence-specific primers.HLAB*08, -DRB1*03, and theA1-B8-DR3haplotype impart predisposition to all three forms of AILD. Homozygosity forDRB1*03represented the strongest risk factor (8.8). HLADRB1*04,which independently confers susceptibility to AIH in adults, was infrequent in AIH-1 and ASC, suggesting protection; and DRB1*15 (DR15)was protective against all forms of AILD. Distinct HLA class II alleles predispose to the different subgroups of juvenile AILDDRB1*03to AIH-1,DRB1*13to ASC, andDRB1*07to AIH-2. TOFA inhibitor clinical trial Possession of homozygousDRB1*03 or of DRB1*13 isassociated with fibrosis at disease onset, and possession of these two genes in addition toDRB1*07is associated with a more severe disease in all three subgroups.

Unique HLA profiles are seen in each subgroup of juvenile AILD. HLA genotype might be useful in predictingresponsiveness to immunosuppressive treatment and course.

Because of their prothrombotic and neuroinflammatory effects, neutrophils and neutrophil extracellular traps (NETs) represent interesting therapeutic targets for spontaneous intracerebral haemorrhage (sICH). We investigated the presence, spatial and temporal distribution of NETs in a human sICH post-mortem study.

From 2005 to 2019, all sICH patients who came to autopsy within the first month after stroke were included and grouped according to the timing of death 72h, 4-7days, 8-15days and >15days after ICH onset. Paraffin-embedded tissue was extracted from four strategic areas haematoma, peri-haematomal area, ipsilateral surrounding brain tissue and a control contralateral area. Myeloperoxidase and histone H3 citrulline were immunolabelled to detect neutrophils and NETs respectively.

Neutrophils were present in the brains of the 14 cases (4 men, median age 78years) and NETs were found in 7/14 cases. Both neutrophils and NETs were detected within the haematoma but also in the surrounding tissue. The appearance of neutrophils and NETs was time-dependent, following a two-wave pattern during the first 72h and between 8 and 15days after ICH onset. Qualitative examination showed that neutrophils and NETs were mainly located around dense fibrin fibres within the haematoma.

These observations provide evidence for NETs infiltration in the brain of patients who die from sICH. NETs might interact with early haemostasis within the haematoma core, and with the surrounding neuroinflammatory response. These findings open research perspectives for NETs in the treatment of sICH injuries.

Expanded access is the use of investigational treatments outside of clinical trials. Results of expanded access studies provide insights into how investigational treatments work in real-world settings. The objective of this study was to evaluate public availability of results of expanded access studies.

Eligible expanded access studies were identified in ClinicalTrials.gov (CT.gov). Publications matching records of individual studies were searched for in Medline and Embase. In addition, we assessed whether results of the included studies were publicly available from other sources including CT.gov, sponsor web sites and conference proceedings.

After median time of 49.5 (interquartile range, 36.7-64.7) months from study completion, the results of 69 out of the 152 included studies (45.39%) were publicly available, either as a journal publication (53 studies; 34.87%) or from other source (16 studies; 10.52%). The percentage of studies whose results were available as a journal publication after 12, 24, 36 and 48 months from study completion was 13.2, 21.1, 33.1 and 35.7%, respectively. The percentage of studies whose results were publicly available from any source (including journal publications) at 12, 24, 36 and 48 months were 19.1, 29.6, 43.2 and 47.5%, respectively.

Results of a considerable proportion of expanded access studies are not publicly available. In view of the growing importance of real-world data, sponsors and principal investigators of those studies should always consider making their findings public.

During investigation of trends within clinical trials, we have identified a high number of clinical trials involving HDAC inhibitors, prompting us to further evaluate the current status of this class of therapeutic agents. In total, we have identified 32 agents with HDAC-inhibiting properties, of which 29 were found to interact with the HDAC enzymes as their primary therapeutic target. In this review, we provide an overview of the clinical drug development highlighting the recent advances and provide analysis of specific trials and, where applicable, chemical structures. We found haematologic neoplasms continue to represent the majority of clinical indications for this class of drugs; however, it is clear that there is an ongoing trend towards diversification. Therapies for non-oncology indications including HIV infection, muscular dystrophies, inflammatory diseases as well as neurodegenerative diseases such as Alzheimer's disease, frontotemporal dementia and Friedreich's ataxia are achieving promising clinical progress.
