Quality of life of patients with scabies

Background  Scabies is a highly contagious disease caused by the mite Sarcoptes scabiei, and the disease is still a major public health problem in many resource-poor regions. Apart from the skin lesions or substantial morbidity, scabies also leads to social stigma. However, quality of life (QoL) has not been investigated in patients with scabies. Objectives  The aim of this study was to assess the impact of scabies on patients’ QoL using the Dermatology Life Quality Index (DLQI) questionnaire, and assess its feasibility and internal consistency. Methods  One hundred consecutive outpatients seeking treatment for scabies in the Department of Dermatology, the Second Hospital of Xi’an Jiaotong University, were assessed for eligibility for this prospective study from 8 August 2008 to 20 December 2008. Sulphur (10%) was selected in the treatment of scabies. Results  A total of 96 patients completed the study. Among them, 78 (81.25%) of patients were considered cured at the end of the study. The mean ± SD DLQI score in our study was 10.09 ± 5.96. QoL of most of (71.9%) our patients has moderately affected. Questions 1 (symptoms), 2 (embarrassment), 7 (work or study) and 9 (sexual difficulties) had the most impact on patients with scabies. Domain 1 (symptoms and feelings) and 5 (personal relationships) scored higher than other domains. There was significant progress of QoL after treatment in our patients. No strong relationship between disease-related characteristics and QoL could be found. Conclusion  Scabies moderately affected the QoL of the patients. Sulphur could be considered as an effective treatment for patients with scabies.
