The knowledge level of rheumatoid arthritis patients about their disease in a developing country. A study in 168 Bangladeshi RA patients.

OBJECTIVES: To assess disease-related knowledge of rheumatoid arthritis (RA) patients PATIENTS AND METHODS: Consecutive RA patients were invited from the rheumatology departments of BSMM University, Dhaka, Bangladesh. The Bangla version of the Patient Knowledge Questionnaire (B-PKQ) was used. Correlations between the B-PKQ scores and clinical-demographic data were measured using Pearson's correlation coefficient. Impact of independent variables on the level of knowledge about RA was analyzed through multiple regression analysis. Possible explanatory variables included the following: age, disease duration, formal education level, and Bangla Health Assessment Questionnaire (B-HAQ) score. Analysis of variance (ANOVA) was used to test the difference between demographical, clinical, and socioeconomic variables. For statistical analysis, SPSS statistics version 20 was used. RESULTS: A total of 168 RA patients could be included. The mean B-PKQ score was 9.84 (range 1-20) from a possible maximum of 30. The mean time for answering the questionnaire was 24.3 min (range 15-34). Low scores were observed in all domains but the lowest were in medications and joint protection/energy conservation. Knowledge level was higher (15.5) in 6 patients who had RA education before enrollment. B-PKQ showed positive correlation with education level (r = 0.338) and negative correlation with HAQ (r = -0.169). The B-PKQ showed no correlation with age, disease duration, having first degree family member with RA, education from other sources (neighbor, RA patient, nurses), or information from mass media. CONCLUSIONS: Disease-related knowledge of Bangladeshi RA patients was poor in all domains. Using these findings, improved education and knowledge will result in better disease control.Key Points• Little is known about the knowledge of RA patients regarding their disease and its treatment in Bangladesh and in developing countries in general.• We found that the knowledge of Bangladeshi RA patients regarding their disease was poor in all domains; it correlated positive with education level and negative with function (HAQ), but showed no correlation with age or disease duration.• The findings of this study can be used for improving current patient education programs by health professionals and through mass media.• Better disease control of RA may be achieved by improving patient knowledge in a developing country like Bangladesh, but also in other parts of the world.

Evidence of Economically Sustainable Village-Scale Microenterprises for Arsenic Remediation in Developing Countries.

Although unknown 25 years ago, natural arsenic contamination of groundwater affects over 50 countries and up to 200 million people. The economic viability was analyzed and modeled of eighty-eight community-based arsenic mitigation systems existing for up to 20 years in India and Bangladesh. The performances of three community-based arsenic mitigation systems that are ethnically different and separated across two different countries were monitored closely for 24 months of self-sustainable, long-term operation at WHO standards through local, paid caretakers. Based on data from the use of hybrid ion exchange materials (HIX-Nano) and the broad set of field operations, Monte Carlo simulations were used to explore the conditions required for self-sustainable operation and job creation in low-income communities (<$2/day/capita). The results from field data and cost modeling provided clear evidence of economic growth and job creation for systems managed by villagers' committee through collection of monthly tariffs. Ethnicity and religion did not have perceptible impacts on day-to-day operations or cumulative long-term revenue. The cost of the treatment technology (i.e., HIX-Nano) had minimal impact on the operational profitability, while number of customers and water delivery significantly affected profitability. Local employment generation with income significantly higher than poverty level was the most enduring outcome and led to enhanced sustainability.

Inflammatory back pain and associated disease conditions among patients with chronic low back pain in Bangladesh.

AIM: Inflammatory back pain (IBP) is the earliest symptom of axial and other forms of spondyloarthritis (SpA). However, there are no published data on prevalence of IBP among patients suffering from chronic low back pain (CLBP) in Bangladesh. In this study, we estimated the prevalence of IBP and the subtypes of SpA in a tertiary hospital in Bangladesh. METHODS: This 1 year cross-sectional study was conducted among 240 CLBP patients in a rheumatology outpatient clinic. Assessment of Spondyloarthritis International Society classification criteria of IBP and predefined recognized classification criteria were followed to define different subtypes of SpA. Means and standard deviations were reported for continuous variables. Descriptive and bi-variate analyses were accordingly performed. RESULTS: Of 240 CLBP patients, 60 (25%) had IBP and 180 (75%) had mechanical back pain (MBP). Among the 60 IBP patients, 52 (86.6%) had predominantly axial SpA (axSpA) and eight (13.4%) had predominantly peripheral spondyloarthritis. In the axSpA group, 49 (94.2%) had radiographic axSpA (rd-axSpA) also known as AS and three (5.8%) had non-radiographic axSpA (nr-axspA). AxSpA patients could be divided into eight (15.35%) with psoriasis, two (3.8%) with reactive arthritis and one patient (1.9%) had arthritis associated with inflammatory bowel disease. Fifty (83.3%) IBP and 73 (40.6%) MBP patients had age at onset of back pain < 40 years. Forty-two (70%) of the IBP and 100 (55.6%) of the MBP patients had normal body mass index. All these differences were statistically significant (P ≤ 0.0001). CONCLUSIONS: Inflammatory back pain is common among patients presenting with CLBP. The commonest cause of IBP is AS, followed by PsA and nr-axSpA.

Prevalence of rheumatic diseases and associated outcomes in rural and urban communities in Bangladesh: a COPCORD study.

OBJECTIVE: To estimate the burden of rheumatic disorders in adults (age >/= 15 yrs) in Bangladeshi rural and urban communities. METHODS: The survey was carried out in a rural community, an urban slum, and an affluent urban community with samples of 2635, 1317, and 1259 adults, respectively. Through door-to-door surveys, trained interviewers identified subjects with musculoskeletal pain. A socio-culturally adapted and validated Bengali version of the COPCORD (Community Oriented Program for Control of Rheumatic Disorders) questionnaire was used. Trained internists and rheumatologists examined the positive respondents using an English COPCORD examination sheet to identify respondents with definite rheumatic disorders and to reach a diagnosis. RESULTS: The overall point prevalence of musculoskeleletal pain was 26.3%. The point prevalence estimates of musculoskeletal pain in rural, urban slum, and affluent urban communities were 26.2% (women 31.3%, men 21.1%), 24.9% (women 27.5%, men 22.6%), and 27.9% (women 35.5%, men 18.6%), respectively. Most commonly affected sites were low back, knees, hips, and shoulders in all 3 communities. The point prevalence of definite rheumatic disorders was 24.0%. The commonest rheumatic disorders were osteoarthritis of the knees, nonspecific low back pain, lumbar spondylosis, fibromyalgia, and soft tissue rheumatism. Their prevalence estimates were 7.5%, 6.6%, 5.0%, 4.4%, and 2.7%, respectively, in the rural, 9.2%, 9.9%, 2.0%, 3.2%, and 2.5%, respectively, in the urban slum, and 10.6%, 9.2%, 2.3%, 3.3%, and 3.3% in the urban affluent community. The point prevalence of functional disability was 25.5%, 23.3%, and 24.8%, respectively, in the rural, urban slum, and urban affluent communities. Among the positive respondents, 22%, 52%, and 22% reported loss of work for durations of 49.3 +/- 47.5, 50.90 +/- 103.3, and 29.25 +/- 56.5 days, respectively, within the previous year. CONCLUSION: Rheumatic disorders are common causes of morbidity, disability, and work loss in rural and urban communities of Bangladesh. Women are affected more frequently than men. Mechanical disorders are more common than inflammatory arthropathies.
