Abstract. Background: A large number of patients with Bell’s palsy fail to recover facial function completely after steroid therapy. Only a few small trials have been conducted to test whether outcomes can be improved by the addition of antiviral therapy. Objective: To evaluate the efficacy of treatment with steroid alone versus steroid + antiviral in a group of patients with moderately severe to severe acute Bell’s palsy. Methods: Fifty eligible patients out of a total of 65 with acute onset Bell’s palsy were randomized to receive the two treatments. Evaluation was performed before starting treatment, after 2 weeks of treatment and 3 months after onset, using the House and Brackmann facial nerve grading system (HB) and the Sunnybrook grading system. This study was registered with ClinicalTrials.gov, number NCT02328079. Results: Both treatments had comparable demographics and clinical scores at baseline. There was greater improvement in the mean HB and Sunnybrook scores of the steroid + antiviral group in comparison to steroid group at 3 months. At the end of the 3rd month, 17 patients (68%) had good recovery and 8 patients (32%) had poor recovery in the steroid group compared with 23 patients (92%) and 2 (8%) respectively in the steroid and antiviral group (p = 0.034). Conclusion: The combination of steroid and antiviral treatment increases the possibility of recovery in moderately severe to complete acute Bell’s palsy.

Abstract Our study aimed to study regulatory T cells (Tregs) and their expression of CD45RA, HLA-DR, and CD39 in preterm and full-term infants. In an observational study, we used a three-color flow cytometry for determination of Tregs and their expression of CD45RA, HLA-DR, and CD39 in preterm and full-term infants. The percentages of CD4+CD25+highFoxp3+, CD39+ Tregs, HLA-DR+ Tregs and the expression of Foxp3+ in CD4+CD25+highFoxp3 Tregs cells were significantly lower in neonates when compared to healthy adult controls. The levels of naïve resting Tregs (CD45RA+Tregs) were significantly higher in neonates than controls. The percentages of CD4+CD25+highFoxp3+Tregs, total CD4+CD25+ and CD4+CD25+high were significantly higher in preterm infants when compared to the full-term group. Moreover, CD45RA+Tregs were significantly higher in preterm than in term infants. We found significant inverse correlations between the gestational age and the levels of both Tregs (r = −0.395, p=0.017) and CD45RA+Tregs (r = −0.422, p=0.010). Relative to full-term, the frequencies, and phenotypes of Tregs were affected by prematurity. A larger longitudinal study with a sufficient number of newborns is needed to investigate the Treg pool of term and preterm infants thoroughly and to explore the association between the Treg pool and clinical variables
