    The drug compliance among patients with diabetes in Sri Lankan setting
    (Endocrine Society of Sri Lanka, 2017) Gunathilake, G.; Kottahachchi, D.; Siyambalapitiya, S.
    INTRODUCTION: Diabetes mellitus is a chronic non-communicable disease that is associated with vascular complications. Treatment of diabetes complications are expensive and it is much more expensive than the treatment for the disease itself. However, most of these vascular complications can be prevented with good glycaemic control and to achieve this, compliance to medication is essential. Similar to most of the other chronic diseases, drug compliance has been poor among patients with diabetes. The objective of this study was to assess the level of drug compliance and the factors that influence the drug compliance among Sri Lankan patients with diabetes. METHOD: Three sets of patients were recruited from three different clinical settings, the diabetes clinic, the medical clinics and the general practitioner clinics in the community. Data were collected using an interviewer administered questionnaire. RESULTS: There were 247 patients recruited for the study and majority were females (80.2%). The majority (79.4%) attended the clinics regularly. However, a good compliance to medication was seen in 38.4% of patients. The large number of tablets that they need to swallow, fear of side effects with long-term drug intake and unclear instructions are the main reasons for poor drug compliance among our patients. CONCLUSIONS: Similar to most of the previously done studies, drug compliance is poor among our patients with diabetes. However, the compliance can be improved by avoiding polypharmacy by using combined pills and with proper patient education regarding drug intake and the side-effects.

    Thyroid gland and male reproductive anomalies among fuel handlers in Gampaha district, Sri Lanka
    (Endocrine Society, 2021) Kottahachchi, D.C.; Warnakularuriya, T.; de Silva, D.; Madagoda, K.; Wadasinghe, D.; Dayanath, B.K.T.P.I.; Siyambalapitiya, S.; Devanarayana, N.
    Introduction:Fuel handlers at petrol stations are continuously exposed to organic solvents from fuel and vehicle emissions. Endocrine disrupting chemicals (EDC) are present in fuel, which are harmful to endocrine organs. Thyroiditis and hypogonadism are reported among fuel handlers. Thyroid gland and male reproductive function anomalies were investigated among fuel handlers in the Gampaha district of Sri Lanka. Method: 43 were recruited from 6 fuel stations in the Gampaha district for the study and 28 age matched male workers who were not exposed to fuel in an occupational setting were recruited as controls. Thyroid gland was examined clinically and TSH, free T4, FSH, LH and Testosterone were done on all the participants. TPO antibody and a thyroid scan was done on the fuel handlers. Results: Median (IQR) age was 38 years (27-46 years). The mean TSH value was 1.62 IU/mL (1.15-2.35) vs 1.33 IU/mL (0.83-1.79) respectively in study and control populations with significantly higher levels in the study population (p=0.023). The median (IQR) TSH value above the reference range was identified in 7% of fuel handlers and all controls were within the normal range, while 16.9% of fuel handlers had a derangement in the TPO levels. On examination, only one control had a small goiter but his T4 and TSH levels were normal. On ultrasound thyroid scans, benign nodules were seen in 2 fuel handlers. TPO levels did not correlate with the TSH levels among the fuel handlers (r=-0.078, p=0.652). Inability to sustain an erection was reported by 35.5% fuel handlers which was significantly higher than controls who reported 5.6% (p=0.019). Premature ejaculation was reported by 27.9% of fuel handlers which was significantly higher than controls (p=0.023). The testosterone levels were significantly higher among fuel handlers compared to controls (p=0.048). The FSH and LH levels positively correlated with each other as expected in each subgroup and the total population (p<0.005). The TSH levels significantly negatively correlated with the testosterone levels among the fuel handlers. (r=- 0.338, p=.0.023). When the fuel handlers with premature ejaculation was considered the FSH, LH, Testosterone levels were not significantly different between the two groups, however the duration of employment was significantly longer among those reporting premature ejaculation. (p=0.024). Conclusion: There are thyroid and reproductive abnormalities among those exposed to fuel in an occupational setting. Disturbances to sexual functions may also be related to alteration of autonomic functions. Limiting exposure to fuel vapor will eliminate these detrimental effects and we propose self-service fuel pumps to be the best alternative to avoid occupational health hazards among fuel handlers.
