Quality of life among tuberculosis (TB), TB retreatment and/or TB-HIV co-infected primary public health care patients in three districts in South Africa.

INTRODUCTION: TB and HIV co-morbidity amount to a massive burden on healthcare systems in many countries. This study investigates health related quality of life among tuberculosis (TB), TB retreatment and TB-HIV co-infected public primary health care patients in three districts in South Africa. METHODS: A cross sectional study was conducted among 4900 TB patients who were in the first month of anti-TB treatment in primary public health care clinics in three districts in South Africa. Quality of life was assessed using the social functioning (SF)-12 Health Survey through face to face interviews. Associations of physical health (Physical health Component Summary = PCS) and mental health (Mental health Component Summary = MCS) were identified using logistic regression analyses. RESULTS: The overall physical and mental health scores were 42.5 and 40.7, respectively. Emotional role, general health and bodily pain had the lowest sub-scale scores, while energy and fatigue and mental health had the highest domain scores. Independent Kruskal-Wallis tests found significant positive effects of being TB-HIV co-infected on the domains of mental health functioning, emotional role, energy and fatigue, social function and physical role, while significant negative effects were observed on general health, bodily pain and physical function. In multivariable analysis higher educational, lower psychological distress, having fewer chronic conditions and being HIV negative were significantly positively associated with PCS, and low poverty, low psychological distress and being HIV positive were positively significantly associated with MCS. CONCLUSION: TB and HIV weaken patients' physical functioning and impair their quality of life. It is imperative that TB control programmes at public health clinics design strategies to improve the quality of health of TB and HIV co-infected patients.

Health-related quality of life (HRQL) in all-patients treated with chemotherapy only: a report from the late effects surveillance system in Germany.

BACKGROUND: The study examines the HRQL in children suffering from ALL over time. PATIENTS: 96 patients (average age 7.1 years) were included, treated with chemotherapy in 15 German study centres between 1997 and 2003. METHODS: The HRQL was assessed based on both the parent report (POQOLS) and the patient self-report (KINDL) at 3 intervals: up to 2 weeks after diagnosis (T1), upon completion of the re-induction therapy (T2) and at the end of the maintenance therapy (T3). To analyse the changes of HRQL over time, the differences between the individual scores (T2-T1 and T3-T1) were calculated and statistically tested. The HRQL results from KINDL were also compared to a sample from the German general population. RESULTS: POQOLS (scale 0 (optimum) to 6): A decrease of HRQL was found in the domain "activity" at T1 (mean score=3.1) and T2 (mean score=2.6). Over time, HRQL improved significantly with a mean score-difference T3-T1=-0.7 (p=0.001). KINDL (scale 0 to 100 (optimum)): The individual HRQL-scores improved over time with the major increases occurring in the domains "physical" with a mean score-difference T2-T1=21.7 (p<0.0001) and a mean score-difference T3-T1=20.6 (p=0.0002) and "mental" with a mean score-difference T2-T1=7.1 (p=0.02) and T3-T1=8.1 (p=0.02). However, the mean overall HRQL-score was significantly lower compared to the general population. CONCLUSIONS: Children with ALL show lower HRQL compared to the general population. Over time, HRQL improved significantly from both the patient and the parent perspective.
