RESULTS The VAS was significantly lower after bilateral submandibular duct ligation at follow-up compared to BoNT-A treatment (mean difference -33, p≤0.001; 95% confidence interval [CI]=-43.3 to -22.9). The mean drooling quotient did not significantly differ between BoNT-A treatment and bilateral submandibular duct ligation at follow-up (3.3, p=0.457; 95% CI=-4.35 to 9.62) or between 8 and 32 weeks (4.7, p=0.188; 95% CI=-2.31 to 11.65). INTERPRETATION BoNT-A treatment and bilateral submandibular duct ligation are both effective treatment modalities for drooling. At 32-week follow-up, subjective drooling severity after bilateral submandibular duct ligation was significantly lower compared to previous BoNT-A injections in participants. However, treatment success with BoNT-A is no precursor to achieving success with bilateral submandibular duct ligation. © 2020 The Authors.

We analyzed vitamin D status and the immune assessment, focusing on T cell subpopulations and dendritic cells (DCs) in a cohort of 17 pediatric 22q11.2DS patients and 17 age-matched healthy subjects. As antigen presenting cells, DCs are the main target of vitamin D, promoting a tolerogenic T-cell response. Patients were subdivided into three groups according to the parameters of phospho-calcium metabolism and serum levels of 25OHD normal values, vitamin D deficiency, and hypoparathyroidism. Different degrees of T cell deficiency, ranging from normal/partial T cell number were observed in the cohort of patients. The group with vitamin D deficiency showed a significant reduction of naïve T cells and a significant increase of central memory T cells compared to controls. In this group the number of circulating DCs was significantly reduced. DC decrease affected both myeloid and plasmacytoid DC subsets (mDCs and pDCs), with the most relevant reduction involving pDCs. A direct correlation between 25OHD levels and recent thymic emigrant (RTE) and DC number was identified. Despite the limited cohort analyzed, our results show that deficiency of the pDC subset in patients with 22q11.2DS may be included among the causative factors of the progressive increase of risk of autoimmune diseases in these patients. Ropsacitinib manufacturer As most patients suffer from increased susceptibility to infections and heightened prevalence of autoimmune disorders, we suggest a potential role of vitamin D supplementation in preventing autoimmune or proinflammatory diseases in 22q11.2DS.

METHODS This non-randomized controlled trial included 357 anterior teeth from 30 Chinese adult patients with skeletal Angle class III malocclusion for whom the proposed treatment was augmented corticotomy. Jaws receiving surgery were allocated to a test group (S group, n = 47) and jaws not receiving surgery were allocated to into a control group (NS group, n = 13). Changes in the periodontal biotype, width of the keratinized gingiva (WKG), and labial and lingual horizontal bone thicknesses (BTs) were compared 6 months after surgery by univariate and multivariate analyses. RESULTS After adjustment for confounding variables, average gains of 0.473 mm in the WKG and 0.649 mm in the labial BT were found in the S group relative to the NS group (p less then 0.05). The odds of transition from a thin periodontal biotype to a thick biotype in the S group were about 230 times those in the NS group, and the odds of the reverse biotype transition in the NS group were about 83 times those in the S group (p less then 0.05). CONCLUSION Within the limitations of the present study, augmented corticotomy is a promising approach to improve insufficient periodontal soft and hard tissues in Chinese adult patients with skeletal Angle class III malocclusion.

Our objective was to evaluate the potential drug-drug interaction between GBP and cetirizine (CTZ), an inhibitor of transporters for organic cations. An open-label, 2-period, crossover, nonrandomized clinical trial was conducted in patients with neuropathic pain to evaluate the effect of CTZ on GBP pharmacokinetics. Twelve participants were treated with a single dose of 300 mg GBP (treatment A) or with 20 mg/d of CTZ for 5 days and 300 mg GBP on the last day of CTZ treatment (treatment B). Blood sampling and pain intensity evaluation were performed up to 36 hours after GBP administration. The interaction of GBP and CTZ with transporters for organic cations was studied in human embryonic kidney (HEK) cells expressing the organic cation transporters (OCTs), multidrug and toxin extrusion proteins (MATEs), and OCTN1. CTZ treatment resulted in reduced area under the concentration-time curve and peak concentration compared with treatment A. In treatment B, the lower plasma concentrations of GBP resulted in reduced pain attenuation. GBP renal clearance was similar between treatments. GBP has low apparent affinity for OCT2 (concentration of an inhibitor where the response [or binding] is reduced by half [IC50 ] 237 µmol/L) and a high apparent affinity for hMATE1 (IC50 1.1 nmol/L), hMATE2-K (IC50 39 nmol/L), and hOCTN1 (IC50 2.1 nmol/L) in HEK cells. At therapeutic concentrations, CTZ interacts with hMATE1 and OCTN1. In summary, CTZ reduced the systemic exposure to GBP and its effect on neuropathic pain attenuation. However, CTZ × GBP interaction is not mediated by the renal transporters. © 2020, The American College of Clinical Pharmacology.Itacitinib is a novel, selective, Janus kinase 1 inhibitor in development for treatment of graft-versus-host disease. The objective of this study was to assess pharmacokinetics and safety of 300-mg itacitinib dosed in participants with normal renal function (n = 10), severe renal impairment (n = 8), and end-stage renal disease (ESRD) on hemodialysis (n = 8). Serial plasma and urine samples (urine from normal and severe groups only) were collected before dosing until 72 hours after dosing. In the ESRD group, itacitinib was evaluated in 2 periods, when dosed before (period 1) and after (period 2) a hemodialysis session. Geometric mean ratios (90% confidence interval) in participants with severe renal impairment, ESRD period 1 and ESRD period 2 relative to participants with normal renal function were 1.65 (1.13-2.39), 0.71 (0.49-1.03), and 0.83 (0.57-1.20) for maximum plasma drug concentration and 2.23 (1.56-3.18), 0.81 (0.57-1.16), and 0.95 (0.66-1.35) for area under the plasma concentration-time curve from time zero to infinity.
