Impact of depression on quality of life in people living with human T cell lymphotropic virus type 1 (HTLV-1) in Salvador, Brazil.

PURPOSE: A previous study found the prevalence of depression in HTLV-1-infected patients to be approximately 30%, but few studies have attempted to correlate depression with quality of life (QOL) in these patients. The present study investigates the association between depression and QOL in people living with HTLV-1. METHODS: A clinical-epidemiological questionnaire, the Mini International Neuropsychiatric Interview and the WHOQOL-Bref were applied to 88 HTLV-1-infected patients (32 with TSP/HAM) at the HTLV Center of the Bahiana School of Medicine and Public Health, Salvador, Brazil. RESULTS: The prevalence of depression among people living with HTLV-1 was 34.1%. Depression was significantly associated with a poor QOL in the physical, psychological, social relationship and environment domains, when controlling for other variables, such as gender, age, time of knowledge of serological diagnosis and presence of tropical spastic paraparesis/HTLV-1associated myelopathy (TSP/HAM). Moreover, patients with TSP/HAM experienced a reduction in their QOL in the physical, psychological and environment domains. CONCLUSION: Our results showed that depression negatively affects the quality of life of people living with HTLV-1, regardless of the presence of TSP/HAM. Since it is possible to improve a patient's QOL by treating depression, psychological evaluations are strongly recommended as a measure to integrate the treatment protocols of HTLV-1 intervention programs.

Integrative and Multidisciplinary Care for People Living With Human T-Cell Lymphotropic Virus in Bahia, Brazil: 20 Years of Experience.

Brazil is home to the highest absolute number of human T-cell lymphotropic virus type-1 (HTLV-1)-infected individuals worldwide; the city of Salvador, Bahia, has the highest prevalence of HTLV-1 infection in Brazil. Due to the complex nature of several diseases associated with this retrovirus, a multidisciplinary health care approach is necessary to care for people living with HTLV-1. The Bahia School of Medicine and Public Health's Integrative Multidisciplinary HTLV Center (CHTLV) has been providing support to people living with HTLV and their families since 2002, striving to ensure physical and mental well-being by addressing biopsychosocial aspects, providing clinical care and follow-up, including to pregnant/postpartum women, as well as comprehensive laboratory diagnostics, psychological therapy, and counseling to family members. To date, CHTLV has served a total of 2,169 HTLV-infected patients. The average patient age is 49.8 (SD 15.9) years, 70.3% are female, most are considered low-income and have low levels of education. The majority (98.9%) are HTLV-1 cases, and approximately 10% have been diagnosed with tropical spastic paraparesis/HTLV-1-associated myelopathy (TSP/HAM), while 2.2% have infective dermatitis and 1.1% have adult T-cell lymphoma. In all, 178 pregnant/postpartum women [mean age: 32.7 (±6.5) years] have received care at CHTLV. Regarding vertical transmission, 53% of breastfed infants screened for HTLV tested positive in their second year of life, nearly 18 times the rate found in non-breastfed infants. This article documents 20 years of experience in implementing an integrative and multidisciplinary care center for people living with HTLV in Bahia, Brazil. Still, significant challenges remain regarding infection control, and HTLV-infected individuals continue to struggle with the obtainment of equitable and efficient healthcare.

HAM/TSP and major depression: the role of age.

OBJECTIVE: To investigate the role of demographic variables in the relationship between the presence of HAM/TSP and current major depression. METHODS: It is a cross-sectional study of 108 HTLV-1 infected patients (47 with TSP/HAM) resident of Salvador, Brazil. The Mini International Neuropsychiatric Interview, Brazilian Version 5 was used to evaluate the presence of depression. Prevalence ratios were used to describe relationship between HAM/TSP and depression. The HAM/TSP classification was carried out according to the criteria proposed by Castro-Costa et al. RESULTS: Prevalence of depression was 37.96%. No association was observed between presence of HAM/TSP and diagnosis of current major depression in the global analysis of patients (PR: 0.94; CI 95%: 0.57-1.55). In the stratified analysis, however, greater prevalence of depression was observed amongst individuals with HAM/TSP in the 18-39 age group (PR: 2.59; CI 95%: 1.36-4.95). CONCLUSION: Our findings suggest that age is an effect modifier in the relationship between HAM/TSP and depression, and this aspect should be considered in future studies on the topic.
