RESUMO

INTRODUCTION: Early diagnosis of gestational diabetes mellitus (GDM) is a prerequisite to reducing fetal and neonatal complications of GDM. OBJECTIVES: (a) To ascertain the prevalence of GDM in a Sri Lankan pregnant population. Using the 75 g oral glucose tolerance test (GTT) and WHO criteria. (b) To establish the predictive value of a 50 g glucose challenge test (GCT) compared to the GTT (c) To compare the outcome of pregnancy in GDM with 'non-diabetic pregnancy' (NDP) STUDY DESIGN: Prospective study on a cohort of pregnant women attending antenatal clinics. SETTING: Sri Jayawardenepura General Hospital (SJGH) RESULTS: Of the 721 patients, 131 (18%) had a positive GCT. 40 (5.5%) patients had GDM. If a one-hour GCT of 7.8 mmol/l was considered suspicious of GDM the sensitivity of the glucose challenge test was 63% and the specificity 84%. Statistically significant differences in the prevalence was found when the women were > 35 years [Relative risk (RR) = 3.87 (95% CI-2.06 to 7.27)] or the body mass index > or = 25. (RR = 2.45 (95 CI-1.30 to 4.61) Presence or absence of high parity, family history of diabetes or recurrent abortions had no significant impact on the prevalence of GDM. Mean birth weight was higher (p < 0.05) in GDM (3615 SD 103) than in NDP (2898 SD 143.6). The likelihood of having a caesarean section was higher (p < 0.01, Relative risk (RR) 2.50, 95% CI 1.56-3.95) in GDM when compared to NDP. A higher incidence of hydramnios (p < 0.01 RR 3.41 95% CI 1.44-8.05) was recorded in GDM when compared to NDP. CONCLUSION: The prevalence of GDM in the antenatal clinics at SJGH is 5.5%. Traditional risk factors did not predict GDM. GDM is associated with a higher risk of caesarean section, hydramnios and macrosomia. Hence screening for GDM should be performed in all pregnant women at 24 to 28 weeks of pregnancy using a GCT.

RESUMO

INTRODUCTION: Neuropathy is considered to be a longterm complication of diabetes. AIMS: To determine the prevalence of peripheral neuropathy in 112 Sri Lankan patients with recently diagnosed non-insulin-dependent diabetes and a control population of 100 people. METHODS: A diagnosis of peripheral neuropathy was made using a clinical symptom score, clinical examination, quantitative sensory testing and electrophysiological studies. RESULTS: 9.8% of diabetic patients at diagnosis had peripheral neuropathy, 2.6% had foot ulcers, 7.1% had signs of neuropathy, abnormal vibration perception threshold and nerve conduction abnormalities and 15.1% had abnormal nerve conduction velocity without signs or symptoms of neuropathy. The peroneal nerve conduction velocity was higher in diabetic patients when compared to controls. There was an inverse correlation between nerve conduction velocity and fasting blood glucose in diabetic patients (p < 0/05). This association was stronger for peroneal nerve conduction velocity (r = -0.73) than for median nerve motor conduction velocity (r = -0.42). CONCLUSIONS: Symptomatic peripheral neuropathy is common among Sri Lankans with newly diagnosed non-insulin-dependent diabetes. This may be due to a later presentation of diabetes or a genetic predisposition.

RESUMO

OBJECTIVE: To determine the prevalence of hyperlipidaemia in Sri Lankan patients with non-insulin dependent diabetes mellitus (NIDDM) and a normal control population. DESIGN: A cross-sectional study. SETTING: Patients with NIDDM randomly selected from a diabetic clinic register and non-diabetic controls randomly selected from an electoral register. PATIENTS: 498 patients with NIDDM (197 females mean age 53.5, SD 6.2 years) and 253 non-diabetic controls (101 females, mean age 53, SD 5.5 years matched for age and sex. METHODS: Diabetes and impaired glucose tolerance (IGT) were excluded in the control group by a 75g oral glucose tolerance test. Total cholesterol, high density cholesterol and triglycerides were determined in fasting blood samples. RESULTS: The prevalence of lipid abnormalities was significantly higher in diabetic patients than in controls. The prevalence of hypercholesterolaemia was 21% vs 14% and that of hypertriglyceridaemia 16% vs 8.3%. Mean fasting blood glucose was higher (9.7 + 2.7) in hyperlipidaemic patients than in normolipidaemic diabetic patients (7.5 + 2.1) CONCLUSIONS: Hyperlipidaemias are common in Sri Lankan patients with NIDDM and screening for them should be an essential component of management of patients with diabetes mellitus.

RESUMO

OBJECTIVE: To determine the prevalence of diabetic retinopathy among patients with non-insulin dependent diabetes (NIDDM) attending a Sri Lankan diabetes clinic and assess the skills of non-ophthalmologist in screening for retinal disease. RESEARCH DESIGN AND METHOD: One thousand and three consecutive diabetic patients were screened for diabetic eye disease using a standardised technique based on the WHO Multinational Study. RESULTS: 31.3% (95% confidence intervals 28.0% to 31.6%) had retinopathy, 23% (95% confidence intervals 21% to 25%) had cataract and 20% (95% confidence intervals 17% to 23%) had previously undetected refraction errors. 4.1% (95% confidence intervals 2.1% to 6.0%) of patients were blind due to advanced retinal disease while 6.2% (95% confidence intervals 5.0% to 7.2%) were blind as a result of cataract. General physicians had a 90.6% sensitivity and 100% specificity in screening for retinal disease. CONCLUSIONS: Retinopathy accounts for significant visual handicap. Untreated cataract is more commonly associated with blindness. Undiagnosed errors of refraction account for significant visual handicap in Sri Lankan diabetic patients. Physicians trained in techniques of retinal screening can correctly assess diabetic retinal changes in a high proportion of patients.
