Transgastric Jejunostomy (PEG-J) for Continuous Infusion of Levodopa-Carbidopa Intestinal Gel: An Approach for Parkinson's Disease Treatment.

BACKGROUND Parkinson's disease (PD) is a neurodegenerative disorder that often requires long-term management of motor symptoms. Continuous infusion of levodopa-carbidopa intestinal gel (LCIG) has shown promising results in alleviating motor fluctuations and improving quality of life. This study aimed to evaluate the efficacy and safety of transgastric jejunostomy (PEG-J) as a delivery method for LCIG in a cohort of 43 PD patients. MATERIAL AND METHODS Forty-three PD patients who were candidates for LCIG therapy underwent transgastric jejunostomy to facilitate continuous infusion of LCIG. The primary outcomes assessed were motor symptom improvement, reduction in motor fluctuations, and medication-related adverse events. Secondary outcomes included changes in quality of life, dyskinesia severity, and healthcare resource utilization. RESULTS The results of this study demonstrated significant improvements in motor symptoms, reduction in motor fluctuations, and enhanced quality of life following PEG-J for LCIG infusion. The treatment was generally well-tolerated, with a low incidence of procedure-related complications. Notably, the use of PEG-J allowed for precise and continuous delivery of LCIG, minimizing variations in drug absorption and ensuring consistent therapeutic levels. CONCLUSIONS Transgastric jejunostomy (PEG-J) offers an effective approach for the continuous infusion of LCIG in Parkinson's disease treatment. This method provides a stable and reliable delivery system, leading to improved symptom control and enhanced quality of life for PD patients.

Remission Factors for Ustekinumab Treatment of Ulcerative Colitis: A Multicenter Retrospective Study of Real-World Data in Japan.

Ustekinumab (UST) is an anti-IL-12/23p40 monoclonal antibody used to treat inflammatory bowel disease. The aim of this retrospective, multicenter study was to investigate the effectiveness of UST administration in achieving remission in patients with ulcerative colitis (UC) and to determine patient characteristics that influence its effectiveness. Of 88 UC patients who received UST from March 2020 to August 2023, 47 with traceable data and for whom 56 weeks had elapsed since the start of treatment received UST to induce remission. The remission rates at 8 weeks were 66% overall, 73.7% for Bio Naïve (never used biologics/JAK inhibitors), and 60.7% for Bio Failure (used biologics/JAK inhibitors) groups. Remission rates at 56 weeks were 70.2% overall, 73.7% for Bio Naïve, and 67.9% for Bio Failure groups. Ustekinumab showed good mid-to-long-term results in the induction of remission of UC in both Bio Naïve and Bio Failure groups. The group showing remission at 8 weeks had a significantly higher non-relapse or continuation rate (proportion of patients with no worsened symptoms necessitating surgery/drug change) at 56 weeks. Predictive factors for achieving remission after UST in UC were female gender, low body mass index, and low lymphocyte-to-monocyte ratio. Thus, UST is effective for moderate-to-severe UC.

Comparison of the Effectiveness of Vedolizumab and Ustekinumab in Patients with Ulcerative Colitis: A Real-World Retrospective Study.

Ulcerative colitis (UC) is a chronic inflammatory disorder of the large intestine. Data on the comparative effectiveness of biological therapies such as vedolizumab (VDZ) and ustekinumab (UST) remain limited. This retrospective study compared the effectiveness and safety of VDZ and UST in UC patients. Between November 2018 and November 2023, 106 patients were included: 64 received VDZ and 42 received UST. Bio-failure was significantly higher (p = 0.005) in the UST group versus the VDZ group. The remission rates at 6, 22, and 54 weeks in VDZ group were 51.6%, 61.3%, and 66.7%. The remission rates at 8, 24, and 56 weeks in the UST group were 66.7%, 65.0%, and 66.7%, respectively. Both treatments were comparable in inducing and maintaining clinical remission over 54-56 weeks, with no significant differences observed in the Lichtiger clinical activity index. Subgroup analyses highlighted the potential short-term effectiveness of UST among cases of bio-failure and a white blood cell level ≥ 9000/µL. Safety profiles were generally favorable, with no significant adverse events. Usutekinumab demonstrated effectiveness as a salvage therapy in patients who failed VDZ. Despite the increased disease severity in the UST group compared to the VDZ group, both groups demonstrated similar remission rates, suggesting UST shows significant efficacy even in moderate to severe UC.
