en: Isolated adrenocorticotropic hormone deficiency presenting with arthritis: A case report

en: This case report describes a case of isolated adrenocorticotropic hormone (ACTH) deficiency that presented with arthritis. Initial investigations, including blood tests, imaging, and musculoskeletal ultrasonography, did not confirm any specific connective tissue disease, making it initially difficult to identify the cause of the arthritis. Subsequent adrenal crisis led to the diagnosis of isolated ACTH deficiency through comprehensive endocrine evaluation. The patient's musculoskeletal symptoms, together with generalised symptoms, were resolved following corticosteroid replacement therapy. This report highlights isolated ACTH deficiency as a rare but one of the causes of polyarticular joint pain and underscores the importance of considering endocrine disorders in the differential diagnosis of unexplained arthritis, particularly when accompanied by systemic symptoms.

en: A novel BRD4 degrader, ARV-825, attenuates lung fibrosis through senolysis and antifibrotic effect.

en: These results suggest that ARV825 may impact the progressive and irreversible course of fibrotic lung diseases.

ja: For senescent cells, ARV825 induced the expression of an apoptosis marker while reducing the expression of BRD4 and senescence markers. On the other hand, for early passage pre-senescent cells, ARV825 reduced the expression of collagen type 1 and α-smooth muscle actin. In an experimental mouse model of lung fibrosis, ARV825 attenuated lung fibrosis and improved lung function. Immunohistochemical staining revealed a significant decrease in the number of senescent alveolar type 2 cells in lung tissue due to ARV825 treatment.

en: A polo-like kinase inhibitor identified by computational repositioning attenuates pulmonary fibrosis.

en: These findings suggest that targeting PLK1 may be a novel therapeutic approach for pulmonary fibrosis by inhibiting lung fibroblast proliferation without affecting lung epithelial cells. In addition, while in silico screening is useful, it is essential to fully determine the biological activities of candidates by wet-lab validation studies.

en: The lymphocyte-specific protein tyrosine kinase-specific inhibitor A-770041 attenuates lung fibrosis via the suppression of TGF-β production in regulatory T-cells.

en: These results suggest that Lck inhibition attenuated lung fibrosis by suppressing TGF-β production in Tregs and support the role of Tregs in the pathogenesis of lung fibrosis.

en: Neuropsychiatric systemic lupus erythematosus with cerebellar vasculitis and obstructive hydrocephalus requiring decompressive craniectomy.

en: A 36-year-old woman who had been diagnosed with systemic lupus erythematosus (SLE) was admitted to our hospital due to increasing disease SLE activity. Despite the intensification of immunosuppressive treatment, headache newly developed and worsened. Magnetic resonance imaging (MRI) revealed spreading of a high-intensity area along the sulci of the bilateral cerebellar hemispheres. She was diagnosed with neuropsychiatric SLE and methylprednisolone (mPSL) pulse therapy was started. However, consciousness disorder due to cerebellar oedema with obstructive hydrocephalus appeared and required decompressive craniectomy. The histological findings of the biopsy specimens from cerebellar vermis were compatible with features of vasculitis. She was successfully treated adding intravenous cyclophosphamide therapy.


en: Clinical features of interstitial pneumonia associated with systemic lupus erythematosus.

en: In SLE cases, IP primarily occurred in male and elderly patients. In addition to the NSIP pattern, the UIP pattern was evident on HRCT scans of IP-related SLE. The survival of SLE patients was unrelated to IP.


en: A case of interstitial pneumonia associated with anti-PL-7 antibody in a patient with rheumatoid arthritis.

en: A 65-year-old female had been treated rheumatoid arthritis (RA), interstitial pneumonia (IP) and nephrotic syndrome with prednisolone and cyclosporine. She was emergently admitted to our hospital due to the worsening exertional dyspnea and severe hypoxemia. Chest computed tomography (CT) showed new diffuse ground-glass opacities (GGOs) with slight consolidations along with bronchovascular bundle were observed in addition to pre-existing reticular shadows in both lungs with lower lobe-predominance. An acute exacerbation (AE) of pre-existing IP triggered by an infection was suspected, and the treatment with antibiotics and corticosteroid pulse therapy improved her general condition and chest radiological findings. Because some auto-antibodies associated with acute/subacute onset IP have recently become available in clinic, we examined those including anti-aminoacyl tRNA synthetase (ARS) antibodies, and found that she was positive for anti-PL-7 antibody. We diagnosed her anti-synthetase syndrome (ASS) without symptom of myositis, and her IP was considered to be ASS-related. The careful consideration is necessary to precisely diagnose and treat the patients with RA-associated interstitial lung diseases as the several etiologies may be overlapped in the same patient. J.
