Case Report: A Promising Treatment Strategy for Noninfectious Uveitis.

Background: Uveitis refers to inflammation in the uvea, retina, retinal blood vessels, and vitreous, which can lead to irreversible eye damage and permanent vision loss. Glucocorticoid drugs are the first-line treatment, but side effects, such as obesity and hyperglycemia, can occur. Therefore, biologics have become a new treatment choice. Case Presentation: A 18-year-old girl developed eye pain and was diagnosed with binocular uveitis. Prednisone 50 mg was administered once a day, and the redness and pain in both eyes improved. Later, the prednisone dose was gradually reduced, and treatment was discontinued 3 years ago. Two years ago, the patient's condition relapsed, with both eyes becoming red and painful. She was administered prednisone 20 mg once daily and adalimumab. Visual acuity in both eyes continued to progressively decrease, accompanied by cataracts. At the same time, the patient experienced complications, including obesity and hyperglycemia. Subsequently, a new treatment regimen, oral prednisone 20 mg once a day, tofacitinib 5 mg twice a day, and methotrexate 10 mg once a week, as well as the use of insulin to control blood sugar, was initiated. One month later, the patient's redness and eye pain eased, and her vision gradually improved. The dosage of prednisone was gradually reduced to 5 mg once daily. At the same time, her blood sugar returned to normal, and insulin was stopped. Outcomes: The patient was treated with tofacitinib for 10 months. Subsequently, her best-corrected visual acuity of the right eye rose from 0.06 to 0.075, and the best-corrected visual acuity of the left eye rose from CF/30 cm to CF/100 cm. Redness and eye pain were relieved, her glucocorticoid consumption reduced from 15 to 2.5 mg, and her blood sugar gradually normalized. Conclusion: This case study shows that tofacitinib relieves ocular inflammation in patients with uveitis and improves eyesight. We believe that JAK inhibitors could be another treatment option for noninfectious uveitis in patients who do not respond to conventional anti-TNF-α inhibitors (such as adalimumab).

Advances in Drug Therapy for Systemic Lupus Erythematosus.

BACKGROUND: Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by a local or systemic inflammatory response. At present, the increasing research results show that the pathogenesis of the disease is complex, and the methods of clinical treatment also show diversity. This review analyzes and summarizes the existing mechanism research and drug treatment methods in order to provide a reference value for further drug research and development. METHOD: We carried out a thorough literature search using databases. According to the main purpose of the article, irrelevant articles were excluded after further examination and directly relevant articles were included. Finally, the information related to the article was summarized. RESULT: In this article, seventy-four articles are included. According to related articles, there are mainly four kinds of drugs, namely antimalarial drugs, glucocorticoids, immunosuppressive agents and biological agents. About fifty-five articles summarized the drugs for the treatment of systemic lupus erythematosus. The rest of the articles were related to the research progress of the mechanism of systemic lupus erythematosus. CONCLUSION: This article describes the pathogenesis of systemic lupus erythematosus, and summarizes the traditional and new therapeutic drugs, which is not only beneficial to the treatment of lupus erythematosus patients, but also plays a vital reference significance for the future development of new systemic lupus erythematosus drugs.

Expression Pattern of Long Non-coding RNA Growth Arrest-specific 5 in the Remission Induction Therapy in Childhood Acute Lymphoblastic Leukemia.

BACKGROUND: Long non-coding RNA growth arrest-specific 5 (GAS5) is deregulated in many cancers because of its role in cell growth arrest and apoptosis. Additionally, GAS5 interacts with glucocorticoid receptor, making it a potential pharmacotranscription marker of glucocorticoid (GC) therapy. In this study, we aimed at analysing GAS5 expression in the remission induction therapy phase of childhood acute lymphoblastic leukemia (ALL), in which GCs are mandatorily used, and to correlate it with therapy response. METHODS: GAS5 expression was measured in peripheral blood mononuclear cells taken from 29 childhood ALL patients at diagnosis, on day 15 and day 33 of remission induction therapy using RT-qPCR methodology. RESULTS: Our results have shown interindividual differences in GAS5 expression at all time points. For each ALL patient, GAS5 expression was higher on day 15 in comparison to its level at diagnosis (p<0.0005). On day 33, the level of GAS5 expression decreased in comparison with day 15 (p<0.0005), but it was still significantly higher than at diagnosis for the majority of patients (p=0.001). Patients whose number of blasts on day 8 was below 100 per µL of peripheral blood had a higher GAS5 expression at diagnosis (p=0.016), and lower ratio day 15/diagnosis (p=0.009). CONCLUSIONS: Our results suggest that the expression level of GAS5 could be a potential marker of therapy response in remission induction therapy of childhood ALL.
