Steroids with and Without Antivirals in the Treatment of Bell’s Palsy: Does It Make any Difference in Recovery? A Study at a Tertiary Care Center, Karachi, Pakistan

Objectives: To compare the pharmacological effects of steroids in comparison to steroids with antiviral drugs for the treatment of Bell’s Palsy. Methods: A total 60 patients were enrolled and segregated equally into two groups, where patients on prednisolone were labeled as group A (Control group), whereas patients on prednisolone + acyclovir were labeled as group B (study group). All patients had House Brackmann score. The control group started oral prednisolone 1 mg/kg for 10 days, whereas the study group started acyclovir 400 mg 4 times a day for 10 days along with prednisolone tablets. Patients were regularly observed till the study was completed. Primary outcome measure was facial nerve recovery. Health-related quality of life and facial appearance were considered secondary outcomes. Results: The primary outcomes assessed as complete recovery from Bell’s Palsy by Brackmann score at week 4 were found in 17/30 (57%) patients and 23/30 (77%) patients at week 8 in the control group. Complete recovery from Bell’s Palsy was also shown in the experimental group (Prednisolone + acyclovir) where 25/30 (83%) patients completed recovery at week 4, while 27/30 (90%) patients at week 8. Comparison of the two groups showed a significant improvement in the study group (prednisolone + acyclovir) (P = 0.047) at week 4 and (P = 0.02) at week 8. The secondary outcomes were assessed as improvement in the quality of life and facial appearance from Bell’s Palsy. Health utility score was 0.84 ± 0.01 in the control group (On prednisolone) with facial appearance score of (Derriford appearance scale 59) 61 ± 28. At week 4, the study group (on prednisolone+ acyclovir) showed 0.88 ± 0.12 score on Health utility index scale-3 and 46 ± 26 score on Derriford appearance scale. Comparison of the quality of life (Health quality index scale-3) and facial appearance among both control and study groups showed a significant improvement in the study group (P = 0.001 and P = 0.005, respectively). Moreover, when health utility score and Derriford appearance were compared among both groups, it showed a significant improvement in the study group (P = 0.001 and 0.016, respectively). Conclusions: The combination of prednisolone with acyclovir is found superior to prednisolone alone, and this combination treatment results in improvement in both recovery and quality of life.
