Recent sequencing studies demonstrated the MYD88 L265P mutation in more than 70% of primary central nervous system lymphomas (PCNSL), and the clinical significance of this mutation has been proposed as diagnostic and prognostic markers in PCNSL. On the other hand, mutational analyses using cell-free DNAs have been reported in a variety of systemic lymphomas. To investigate how sensitively the MYD88 L265P mutation can be identified in cell-free DNA from PCNSL patients, we performed droplet digital PCR (ddPCR) and targeted deep sequencing (TDS) in consecutive 14 PCNSL patients from whom paired tumor-derived DNA and cell-free DNA was available at diagnosis...

Giant cell arteritis (GCA) and Takayasu arteritis (TAK) are the two main large vessel vasculitides. They share some similarities regarding their clinical, radiological and histological presentations but some pathogenic processes in GCA and TAK are activated differently, thus explaining their different sensitivity to biological therapies. The treatment of GCA and TAK essentially relies on glucocorticoids. However, thanks to major progress in our understanding of their pathogenesis, the role of biological therapies in the treatment of these two vasculitides is expanding, especially in relapsing or refractory diseases...

JiGuang Guo, GuoWu Zhang, Dan Tang, JianBin Zhang
RATIONALE: The initial symptoms and signs of Takayasu arteritis vary due to the heterogeneity of affected vessels. Moreover, the vascular lesions are difficult to detect at initial presentation, making diagnosis even more challenging. Although cases of aortic dissection with arteritis history have been reported, Takayasu arteritis in men with aortic dissection as initial presentation is very rare. PATIENT CONCERNS: A 37-year-old man presenting with persistent chest and back pain for 6 days was transferred to our hospital for further treatment...

Nodular glomerulosclerosis -as it was originally described by Kimmelstiel and Wilson- is the main pathognomonic lesion of diabetic nephropathy. However, this particular pattern can also be seen in other conditions such as membranoproliferative glomerulonephritis, light or heavy chain deposition disease, amyloidosis, fibrillary and immunotactoid glomerulonephritis and Takayasu's arteritis. History of diabetes as well as other clinical and pathological features are of crucial importance in order to determine the precise cause of nodular glomerulosclerosis...

Pathogenic variants in genes, which encode DNA repair and damage response proteins, result in a number of genomic instability syndromes with features of accelerated aging. ERCC4 (XPF) encodes a protein that forms a complex with ERCC1 and is required for the 5' incision during nucleotide excision repair. ERCC4 is also FANCQ, illustrating a critical role in interstrand crosslink repair. Pathogenic variants in this gene cause xeroderma pigmentosum, XFE progeroid syndrome, Cockayne syndrome (CS), and Fanconi anemia...

Adipose-derived stem cells (AdSCs) have recently been considered a useful treatment tool for autoimmune disease because of their anti-inflammatory and immunosuppressive effects. We investigated the therapeutic effect of intravenous AdSC transplantation in a mouse model of bleomycin-induced lung injury. AdSCs accumulated in the pulmonary interstitium and inhibited both inflammation and fibrosis in the lung, markedly improving the survival rate of mice with bleomycin-induced lung injury in a cell number-dependent manner...

INTRODUCTION: Long-term outcome studies in Takayasu arteritis (TA) are few and limited by small sample size. In this study, we analysed the outcome of treatment in a large series of TA patients with a minimum follow-up period of ≥12 months by objective instruments. MATERIALS AND METHODS: Patients with TA satisfying the 1990 ACR, Ishikawa's, Sharma's or EULAR/PRESS criteria were recruited from our clinics between 1998 and 2016. Only patients with a minimum follow up of 12 months were studied...

Hearing loss has been rarely reported in Takayasu's arteritis, may present as Sudden Sensorineural Hearing Loss, and usually responds well to corticosteroid therapy. Hyperbaric Oxygen Therapy is commonly used as a supplementary treatment to corticosteroids for Sudden Sensorineural Hearing Loss. We present the case of a 36-year-old woman with Takayasu's arteritis who had two episodes of sudden hearing loss involving one ear at a time with an 11-month delay between each episode. During the first episode, the patient was treated with high-dose intramuscular corticosteroids with a temporary improvement of auditory threshold that deteriorated 14 days after cessation of therapy...

Immunohistochemical investigation of aquaporin (AQP)1 and AQP3 was performed in human skin wounds obtained from forensic autopsy cases. A total of 55 human skin wounds of different postinfliction intervals were collected as follows: group I, 0-3 days (n = 16); II, 4-7 days (n = 11); III, 9-14 days (n = 16); and IV, 17-21 days (n = 12). In uninjured skin samples, AQP1 and AQP3 could be slightly detected in dermal vessels and keratinocytes, respectively. The percentage of AQP1(+) vessels and the number of AQP3(+) keratinocytes were apparently elevated in accordance with wound ages...

GCA shares many clinical features with PMR and Takayasu arteritis. The current mainstay of therapy for all three conditions is glucocorticoid therapy. Given the chronic, relapsing nature of these conditions and the morbidity associated with glucocorticoid therapy, there is a need for better treatment options to induce and sustain remission with fewer adverse effects. Conventional immunosuppressive treatments have been studied and have a modest effect. There is a keen interest in biologic therapies with studies showing the efficacy of IL-6 antagonists in PMR and GCA...

Precise genome editing via homology-directed repair (HDR) in targeted cells, particularly in vivo, provides an invaluable tool for biomedical research. However, HDR has been considered to be largely restricted to dividing cells, making it challenging to apply the technique in postmitotic neurons. Here we show that precise genome editing via HDR is possible in mature postmitotic neurons as well as mitotic cells in mice brain by combining CRISPR-Cas9-mediated DNA cleavage and the efficient delivery of donor template with adeno-associated virus (AAV)...
