OBJECTIVES: Molluscum contagiosum (MC) is viral skin infection that is most commonly observed in children. Zinc homeostasis is essential for proper immune function, especially in host-virus interactions. This study aimed to investigate the effectiveness of oral zinc sulfate treatment in children with MC.

METHODS: The subjects included 23 children with MC and 30 age/sex-matched healthy children as controls. Children with MC received oral zinc sulfate for 2 mo, and serum zinc levels were measured before and after the treatment period. Patients were examined every 4 wk for evidence of partial or complete lesion regression. Lesion numbers were recorded before treatment and during follow up.

RESULTS: The mean serum zinc levels in children with MC did not differ from those in controls (80.57 ± 10.14 vs 81.90 ± 8.47 μg/dL, respectively, P = 0.370). After zinc sulfate supplementation, the mean serum zinc levels increased from 80.57 ± 10.14 to 100.5 ± 9.95 μg/dL (P < 0.001) in subjects with MC. After a 2-mo treatment period, six subjects exhibited resolution of lesions at the 1-mo follow up, 10 subjects at the 2-mo follow-up, and three subjects at the 3-mo follow up. Disease recurrence was not observed. A 6-y-old boy and two 4-y-old girls without other systemic symptoms had MC lesions that persisted after zinc sulfate therapy and throughout the 1-y follow up. One female subject experienced complete recovery in after treatment month 4, but recurrence was observed in month 7 and persisted for 18 mo.

CONCLUSIONS: Our findings support the use of oral zinc sulfate as a therapy for children with MC.
