Chronic neuropathic pain emerges as a challenge in the treatment of leprosy patients aſter multidrug therapy discharge. e aim
of this study was to determine the quality of life and its repercussions in leprosy patients with chronic pain. We studied male
and female patients with chronic neuropathic pain in the last year. Neuropathic pain was confirmed using Douleur Neuropathique
en 4 (DN4) and its intensity evaluated by visual analogue scale (VAS). A general questionnaire was applied to evaluate quality
of life (WHOQOL-bref). Statistical analyses were composed by descriptive and central tendency. Spearman correlation was used
to identify the relation between pain intensity, quality of life domains, and facets. Multiple linear regressions were performed to
verify the influence of pain intensity on each facet. Neuropathic pain patients scored worst in physical and environment domains.
e low facets were related to pain and discomfort, thinking and concentration, sexual activity, and recreation opportunities. Pain
intensity has a high negative influence on psychological domain and recreation opportunities. ese findings should contribute to
the development of rehabilitation programs considering patients needs to improve their quality of life and true social reintegration.
1. Introduction
Leprosy is a chronic granulomatous infection, principally
affecting the skin and peripheral nerves, caused by Mycobac-
terium leprae [1]. Neuropathic pain is a common complaint
due to leprosy-induced neuritis, whether spontaneous or
upon palpation of a nerve trunk (silent neuritis), which
may be associated with impairment of function [1–6]. In
addition to not knowing the precise number of patients who
develop disabilities aſter multidrug therapy (MDT), chronic
pain arises as a new disabling condition during or aſter
bacteriological treatment [7–12].
e International Association for the Study of Pain
(IASP) defined pain as an “unpleasant sensory and emotional
experience associated with actual or potential tissue damage,
or described in terms of such damage.” Neuropathic pain
is defined as “pain arising as a direct consequence of a
lesion or disease affecting the somatosensory system [13, 14].
According to new theories, pain is a subjective experience
influenced by a combination of cortical mechanisms [15].
It is widely believed that pain has a profound effect on
a person’s quality of life (QoL). Considering that leprosy
causes sensory loss, it was expected that patients do not
experience pain, and it has not been well studied in leprosy
[10]. erefore, a lack of knowledge persists regarding chronic
pain in leprosy [12]. e aim of this study was to examine the
repercussions of chronic pain in leprosy patients’ QoL.
