Prevalence of depressive symptoms and related risk factors in Japanese patients with pulmonary nontuberculous mycobacteriosis.

The objective of this study was to administer commonly used tools, the Center for Epidemiological Studies Depression Scale (CES-D) and the Hospital Anxiety and Depression Scale - Depression subscale (HADS-D), to screen for depressive symptoms in patients with nontuberculous mycobacterial pulmonary disease (NTM-PD). In addition, we sought to identify whether differences existed in the prevalence of depressive symptoms as assessed by CES-D and HADS-D, and by various predictors of depression. The presence of depressive symptoms in 95 patients with NTM-PD was assessed using the CES-D and HADS-D. Data regarding age, body mass index, pulmonary function, dyspnea, cough, and exercise capacity were obtained to examine their independent contribution as predictors of depressive symptoms. The prevalence of depressive symptoms was 37.9% based on CES-D and 26.3% based on HADS-D. The prevalence of depressive symptoms based on CES-D and HADS-D revealed significant differences between the two instruments. Analysis suggested that the presence of cough is a significant predictor of depressive symptoms as assessed by both CES-D and HADS-D. Countermeasures are necessary because some patients with NTM-PD disease have depressive symptoms. It is possible that assessment of the prevalence of depressive symptoms differs in accordance with the screening tool used.

Health-related quality of life, comorbidities and mortality in pulmonary nontuberculous mycobacterial infections: A systematic review.

Nontuberculous mycobacterial (NTM) infections are increasing in disease frequency worldwide. This systematic review examines health-related quality of life (HRQOL), comorbidities and mortality associated with pulmonary NTM disease. We searched MEDLINE, EMBASE, CINAHL, Scopus Life Sciences, conference proceedings and Google (earliest date available to February 2015) for primary studies. Eligible studies compared populations with and without pulmonary NTM disease in high-income jurisdictions. We excluded studies on HIV/AIDS. All languages were accepted. Two reviewers followed MOOSE and PRISMA reporting guidelines and independently appraised quality using STROBE. All studies were summarized qualitatively regardless of quality. Of 3193 citations screened, we included 17 studies mostly from Taiwan (n = 5) and the USA (n = 4). Two studies assessed HRQOL; one assessed comorbidities, 11 assessed mortality, and three assessed multiple outcomes. Populations with pulmonary NTM reported significantly worse or similar HRQOL than the general population, depending on the instruments used. Some suggested greater prevalence of having bronchiectasis (n = 2) and greater risk of developing pulmonary tuberculosis (n = 1). Most (n = 7) suggested no difference in mortality, although only one was age-matched and gender-matched to the general population. Four suggested NTM populations had higher mortality-two of which compared with the general population and were deemed of high quality, while two compared with non-NTM patients from hospital. High clinical heterogeneity in study design may explain discordant results. Bias assessments and controlling for confounding were carried out poorly. No consistent trends were observed although there is suggestion of an increased health burden from respiratory diseases and increased mortality associated with pulmonary NTM disease.

Improvement in Quality of Life after Therapy for Mycobacterium abscessus Group Lung Infection. A Prospective Cohort Study.

RATIONALE: Mycobacterium abscessus group lung infection is characterized by low cure rates. Improvement in quality of life may be a reasonable treatment goal. OBJECTIVES: The objective of this study was to evaluate change in quality of life in response to therapy, predictors of improvement in quality of life, and association of quality of life with traditional outcome measures. METHODS: Forty-seven patients were treated for Mycobacterium abscessus group lung infection (including one with Mycobacterium chelonae) and were followed prospectively for 2 years between December 2009 and May 2012. St. George's Respiratory Questionnaire (SGRQ) was administered, chest computed tomography (CT) imaging was carried out, and culture data were collected at multiple time points. Predictors of improvement in the SGRQ total score greater than or equal to a minimal clinically important difference (MCID) at 12 months were evaluated. MEASUREMENTS AND MAIN RESULTS: Patients were 85% female and 94% white, with a mean age of 65 years. Nine (20%) had a genetic diagnosis of cystic fibrosis (none F508del homozygous). Coinfection with Mycobacterium avium complex occurred in 28% and Pseudomonas in 26%. Chest CT imaging universally indicated bronchiectasis and nodules; 51% had lung cavities. Treatment included a mean of 17 months of antibiotics, and lung resection in 34%. Seventeen patients with M. avium complex (36%) and one with Mycobacterium kansasii were treated for coinfection. The mean SGRQ total score (SD) at baseline was 35 (20). At all follow-up time points, the mean SGRQ total score (SD) was significantly lower (better) than at baseline: 27 (17) at 3 months, P < 0.01; 27 (19) at 6 months, P < 0.01; 27 (20) at 12 months, P < 0.01; and 30 (22) at 24 months, P = 0.02. At 12 and 24 months, respectively, 60% and 56% had improvement greater than or equal to the MCID in SGRQ total score. Improvement greater than or equal to the MCID at 12 months was positively associated with a history of respiratory exacerbation, isolate susceptible to imipenem-cilastatin, and lung resection surgery, and negatively associated with nodules >4 mm in diameter on chest CT imaging, but these associations were not statistically significant in multivariable analysis. At 24 months, 16 patients (48%) with complete data were culture negative for 1 year and had discontinued M. abscessus group treatment. CONCLUSIONS: Quality of life was a sensitive indicator of treatment response and has the potential to be a useful parameter to guide treatment.

Factors associated with quality of life measured by EQ-5D in patients with nontuberculous mycobacterial pulmonary disease.

PURPOSE: The impact of pulmonary nontuberculous mycobacterial (pNTM) disease on health-related quality of life (HRQoL) has not received significant attention in the literature. In this study, we compared the HRQoL in patients with pNTM disease and healthy subjects and identified influencing factors using EuroQol 5D (EQ-5D) data. METHODS: The present study used an age- and sex-matched case-control analysis from a cohort of 85 pNTM patients and 340 participants from a national survey. Baseline EQ-5D utility scores and EQ-5D visual analog scale (VAS) scores were measured in both groups. In patients with pNTM disease, the factors affecting EQ-5D were identified using multiple linear regression analysis. RESULTS: While the median EQ-5D VAS scores were lower in pNTM patients than in the control subjects (pNTM, 70; control, 80; P < 0.001), the median EQ-5D utility scores were similar in two groups (both, 1.000, P = 0.878). Interestingly, the percentage of subjects reporting problems on the anxiety/depression dimension was higher for patients with pNTM disease (18.8 %) compared with the control subjects (11.5 %, P = 0.07). In multivariate analysis, increasing severity of forced expired volume in one second (FEV1) decline was associated with a significant decrease in EQ-5D scores of pNTM patients. CONCLUSIONS: This study suggested the EQ-5D may not be useful instrument in pNTM patients due to ceiling effect of EQ-5D and mild disease activity. Patients with pNTM disease tended to report more reduced health status and more problems with anxiety/depression than the healthy controls. Lung function, measured by FEV1, was independently associated with EQ-5D scores in patients with pNTM disease.

[Knowledge-attitudes-practices survey of the Songololo population (D.R. Congo) about Buruli ulcers]. / Enquête connaissances-attitudes-pratiques (CAP) de la population de Songololo (R.D. Congo) sur l'ulcère de Buruli.

The Buruli ulcer (B. U.) is rampant in many tropical and subtropical countries. In D.R. of Congo, some cases of Buruli ulcer have been reported between 1950 and 1970 in the endemic focus of Songololo-Kimpese (Lower-Congo Province). The objective of this study was to provide some anthropological knowledge for better treatment of this pathology; to confirm the presence of Buruli ulcer in that focus and to describe general caracteristics of the subjects. This disease looked upon as "mbasu" (in the Ndibu population in majority in that focus) is experienced as a malediction, or punishment. The success of a program to fight against Buruli ulcer lies on health education which takes into account the representation systems of diseases.

Psychosocial aspects of health seeking behaviours of patients with Buruli ulcer in southern Benin.

We investigated cultural beliefs and psychosocial factors associated with Buruli ulcer in southern Benin in order to elaborate and deliver appropriate health education messages. We conducted a qualitative study among 130 adults and 30 children in Zou province, a highly endemic region. Focus group interviews of inhabitants, patients and their assistants, health care professionals and traditional healers took place in Dasso, Ouinhi, Sagon and Zagnanado. Drawing sessions followed by individual interviews were organized among school children in Dasso and Sagon. We found that although Buruli ulcer is well known and recognized - even at a very early stage of the disease - and perceived as threatening, most people are reluctant to seek treatment at the health care centre. They are unclear about the origin of the disease (environmental factors or sorcery) and treatment is considered devastating, expensive and ineffective in some cases.
