Abelson Tyrosine Kinase Inhibitors in Parkinson's Disease and Lewy Body Dementia: A Systematic Review, Meta-analysis, and Meta-regression.

BACKGROUND: Alpha-synucleinopathies are incurable neurodegenerative diseases. Abelson tyrosine kinase inhibitors (Abl TKIs) may be disease-modifying therapies. This systematic review, meta-analysis, and meta-regression evaluated the use of Abl TKIs in their treatment. METHODS: We searched PubMed, Embase, and Cochrane databases for trials using Abl TKIs in patients with Parkinson's disease and Lewy body dementia published until July 2023. The outcome was the change in the MDS-UPDRS-III (Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale III). DerSimonian-Laird random-effects model was used to calculate the pooled effect estimates. Leave-one-out forest plots were used for the sensitivity analysis, and meta-regression (restricted maximum likelihood) was performed. RESULTS: Five studies (197 patients) were included. Nilotinib 300 mg had an effect size of -1.154 (95% confidence interval [CI], -3.000 to 0.692). Nilotinib 150 mg and bosutinib 100 mg versus placebo yielded 0.82 (95% CI, -3.76 to 5.41). Sensitivity analysis showed that 1 trial changed the significance of the nilotinib 300 mg single-arm analysis (MD = -1.723; 95% CI, -2.178 to -1.268). Meta-regression revealed that lower age (EC = -0.9103, SE = 0.2286, P < 0.0001) and higher baseline MDS-UPDRS-III scores (EC = 0.1210, SE = 0.0168, P < 0.0001) could explain the inefficacy of nilotinib 300 mg. CONCLUSIONS: Nilotinib (300 mg) proved effective postsensitivity analysis, unlike lower doses and bosutinib in Parkinson's disease/Lewy body dementia. Abl TKIs showed reduced efficacy in younger, more impaired patients, indicating the need for further testing with higher-potency drugs in patients who have diseases that are in the early stage but with a later onset.

Safety and efficacy of sotagliflozin in patients with type II diabetes mellitus and chronic kidney disease: a meta-analysis of randomized controlled trials.

BACKGROUND: Sotagliflozin is a dual sodium-glucose co-transporter 1 and 2 inhibitor that increases glucosuria and natriuresis in patients with type 2 diabetes mellitus (T2DM). However, the safety and efficacy in patients with concomitant chronic kidney disease (CKD) remains unclear. Therefore, we aimed to conduct a meta-analysis to evaluate the current evidence in this regard. METHODS: We searched PubMed, Embase, Cochrane, and Web of Science for randomized controlled clinical trials on the safety and efficacy of Sotagliflozin in patients with T2DM and CKD compared with placebo. Statistical analysis was performed using RevMan 5.4. Heterogeneity was assessed with I2 statistics. The study was recorded in PROSPERO registry (CRD42023449631). RESULTS : We included three studies totaling 11,648 patients followed for 15.7 ± 5.9 months. Reduction in HbA1C (mean difference - 0.33%; 95% CI [- 0.54, - 0.11]; p = 0.003; I2 = 100%) and weight (mean difference - 1.01 kg; 95% CI [- 1.17, - 0.86]; p < 0.00001; I2 = 96%) were significantly higher in the Sotagliflozin group compared with placebo. All-cause mortality (RR 0.98; 95% CI [0.81, 1.20]; p = 0.87; I2 = 0%) and major adverse cardiovascular events (RR 0.70; 95% CI [0.40, 1.21]; p = 0.20; I2 = 39%) were not significantly different between groups. However, estimated glomerular filtration rate reduction (mean difference - 0.95; 95% CI [- 1.32, - 0.58]; p < 0.00001; I2 = 98%), genital mycotic infections (RR 2.73; 95% CI [1.96, 3.79]; p < 0.00001; I2 = 0%), diarrhea (RR 1.42; 95% CI [1.24. 1.63]; p < 0.00001; I2 = 0%) and volume depletion (RR 1.31; 95% CI [1.11, 1.56]; p = 0.002; I2 = 0%) were more common with Sotagliflozin. CONCLUSIONS: In patients with T2DM and CKD, Sotagliflozin appears to be effective for glycemic control and weight loss. Although the medication seemed safe concerning mortality and cardiovascular events, it induced estimated glomerular filtration rate reduction, and was associated with a higher risk of genital mycotic infections, diarrhea, and volume depletion.

Inherited Fanconi syndrome.

BACKGROUND: Fanconi-Debré-de Toni syndrome (also known as Fanconi renotubular syndrome, or FRST) profoundly increased the understanding of the functions of the proximal convoluted tubule (PCT) and provided important insights into the pathophysiology of several kidney diseases and drug toxicities. DATA SOURCES: We searched Pubmed and Scopus databases to find relevant articles about FRST. This review article focuses on the physiology of the PCT, as well as on the physiopathology of FRST in children, its diagnosis, and treatment. RESULTS: FRST encompasses a wide variety of inherited and acquired PCT alterations that lead to impairment of PCT reabsorption. In children, FRST often presents as a secondary feature of systemic disorders that impair energy supply, such as Lowe's syndrome, Dent's disease, cystinosis, hereditary fructose intolerance, galactosemia, tyrosinemia, Alport syndrome, and Wilson's disease. Although rare, congenital causes of FRST greatly impact the morbidity and mortality of patients and impose diagnostic challenges. Furthermore, its treatment is diverse and considers the ability of the clinician to identify the correct etiology of the disease. CONCLUSION: The early diagnosis and treatment of pediatric patients with FRST improve the prognosis and the quality of life.
