Challenges for improving quality of life in Chagas disease

Manifestations and strategies of coping with Chagas Disease that interfere in the quality of life of the individual: a systematic review

We aimed to identify the manifestations and coping strategies of Chagas disease that influence the quality of life of the affected subject. This is a literature systematic review carried out in PubMed, SciELO and Lilacs databases, through which sixpapers were retrieved, in addition to six publications identified with the verification of the bibliographic list and four papers through manual search, which were independently evaluated by two reviewers. The variables addressed were set in the thematic axes manifestations of Chagas disease that interfere in the quality of life of the individual and coping strategies that influence the quality of life of patients affected by Chagas disease, subdivided into three realms, namely, physical, psychological and social. The results seen in all addressed realms evidenced a quality of life compromised by the disease, measures mostly limited to the patient's physical realm and incipient records of studies in the area. We suggest further exploring the proposed theme, believing that knowledge of the patient living with the disease promotes the development of effective health intervention strategies.

Quality of life and associated factors in patients with chronic Chagas disease

OBJECTIVES

To evaluate the quality of life (QoL) of patients with Chagas disease (CD) and the association between QoL domains and several clinical, socioeconomic and lifestyle characteristics of this population.

METHODS

Cross-sectional observational study conducted from March 2014 to March 2017 including a total of 361 outpatients followed at Evandro Chagas National Institute of Infectious Disease, Brazil. QoL was assessed using the Portuguese shorter version of the original WHO Quality of Life questionnaire (WHOQOL-BREF). Information about clinical CD presentation, presence of comorbidities, functional class, previous benznidazole treatment, socioeconomic profile and lifestyle was also obtained.

RESULTS

Environment and physical domains presented the worst QoL scores, while the social relationship domain presented the highest score. Multivariate regression analysis demonstrated that variables independently associated with QoL were functional class, sex, clinical presentation of CD, sleep duration, schooling, physical activity level, smoking, income per capita and residents by domicile.

CONCLUSIONS

The low socioeconomic status and the physical limitations imposed by the disease presented an important impact on the QoL reduction among CD patients, especially on environment and physical domains. Strategies to improve QoL among CD patients should be tailored and consider many different variables to maximise improvements not only of patients' physical but also of their mental health.
