Translational research for Diabetes Self-Management in Sri Lanka: A randomized controlled trial.

AIMS: The study tested the hypothesis that a theory driven Diabetes Self-Management (DSM) intervention delivered by trained nurses would result in a clinically significant improvement in glycaemic control. METHODS: Patients with an HbA1c >7.5% (58mmol/mol) and free of diabetes complications were enrolled into a randomized controlled trial (n=85). Intervention consisted of four sessions and monthly follow up for 6 months. Biochemical tests, and diet and physical activity assessments were done in both groups. Analysis of covariance was used to test the effectiveness of the intervention. RESULTS: At 6 months, there was a significant difference (P=0.001) in HbA1c between the groups controlling for baseline values and other variables. Based on the primary outcome, 28% in the intervention group achieved the target value of 6.5% HbA1c, compared to 8% in the "usual care" group (P<0.001; η(2)=0.65). The reduction in total energy intake and increase in physical activity was significant in the intervention group between baseline and follow up. CONCLUSIONS: The DSM intervention has resulted in a clinically significant impact on glycaemia, change in diet and physical activity, and has demonstrated the feasibility of using it within existing care arrangements in a developing country setting.

The burden of diabetes mellitus and impaired fasting glucose in an urban population of Sri Lanka.

AIMS: To describe the burden of diabetes mellitus and impaired fasting glucose in middle-aged residents (35-64 years) in an urban area of Sri Lanka. METHODS: A cross-sectional survey was conducted in the Ragama Medical Officer of Health area, from which 2986 participants (1349 men and 1637 women) were randomly selected from the electoral registry between January and December 2007. The participants underwent a physical examination and had their height, weight, waist and hip circumferences and blood pressure measured by trained personnel. Fasting blood samples were taken for measurement of glucose, HbA(1c) and lipids. The prevalence of diabetes (fasting plasma glucose > 7 mmol/l) and impaired fasting glycaemia (fasting plasma glucose 5.6-6.9 mmol/l) and major predictors of diabetes in Sri Lanka were estimated from the population-based data. RESULTS: Age-adjusted prevalence of diabetes mellitus in this urban population was 20.3% in men and 19.8% in women. Through the present screening, 263 patients with diabetes and 1262 with impaired fasting glucose levels were identified. The prevalence of newly detected diabetes was 35.7% of all patients with diabetes. Among patients with diabetes, only 23.8% were optimally controlled. In the regression models, high BMI, high waist circumference, high blood pressure and hypercholesterolaemia increased the fasting plasma glucose concentration, independent of age, sex and a family history of diabetes. CONCLUSIONS: Our data demonstrate the heavy burden of diabetes in this urban population. Short- and long-term control strategies are required, not only for optimal therapy among those affected, but also for nationwide primary prevention of diabetes.

Antenatal care provided and its quality in field clinics in Gampaha District, Sri Lanka.

A descriptive cross-sectional study was carried out in the Gampaha District in Sri Lanka to assess the quality of care provided at antenatal field clinics. Checklists were used to assess the structure and process attributes of quality. An interviewer administered questionnaire assessed the quality of information provided to the clients and client satisfaction. The findings indicated that several resource components need upgrading in the district. The majority of clinics did not have adequate seating arrangements, lacked a footstool, a height measuring instrument and Vitamin C. Less than 50% of the staff were present at 8.00 a.m. in eight clinics. Health education material was substandard in nine clinics. No supervisory notes were made during the preceding year in fourteen clinics. Testing urine for sugar and albumin was substandard in 11 and eight clinics, respectively. Physical examination of pregnant females was substandard in all 20 clinics. No information was provided on some routine procedures carried out at the clinic such as blood pressure monitoring, weight gain and vaccines given. Client satisfaction exceeded 95% in all aspects except building and infrastructure and time spent at the clinic.

Anti-tuberculosis drug inducd hepatitis - a Sri Lankan experience.

OBJECTIVE: To assess the incidence of anti-tuberculosis (TB) drug induced hepatitis (AIH) in Sri Lankan patients, determine risk factors of AIH, and to address management options in AIH. DESIGN: A prospective study. SETTING: Chest Hospital, Welisara, Sri Lanka, from April 2001 to April 2002. PATIENTS: Seven hundred and eighty three patients with a confirmed diagnosis of TB and resident in the Colombo and Gampaha districts who presented to Chest Hospital, Welisara, Sri Lanka. METHODS: WHO recommended treatment was commenced in all cases. AIH was diagnosed when patients complained of decreased appetite with nausea or vomiting and elevated serum bilirubin (SB; >1.1 mg/dL) or elevated serum alanine transferase (ALT; > 3 times upper limit of normal). RESULTS: Of 783 enrolled patients, 74 (9.5%) developed AIH, the majority (58%) developing AIH within the first 2 weeks of the intensive phase of treatment. AIH was more common among patients over 60 years (p = 0.018), who developed pulmonary TB (p = 0.028), and in patients weighing 33-55 kg (p = 0.004). Age, weight and rifampicin overdosage were significant predictors of AIH. Of the 74 AIH patients, standard treatment was restarted in 60, treatment modified in six, two defaulted and six died. CONCLUSIONS: The incidence of AIH in Sri Lanka is 9.5% in treated patients. AIH was associated with age, low body weight and rifampicin overdosage.
