Zero prevalence of diabetes in camel milk consuming Raica community of north-west Rajasthan, India.

OBJECTIVES: Preliminary trials reflected the low prevalence of diabetes in Raica community consuming camel milk habitually. Our objective was to describe the prevalence and clinical factors associated with impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and diabetes (DM) among adults (>or=20 years) in large population group. DESIGN: Population based, cross sectional study METHODS: 2099 participants from different villages of north-west Rajasthan were selected using stratified sampling of a representative Raica and non-Raica Community, consuming or not consuming camel milk. Demographic, clinical, anthropometric parameters were obtained and oral glucose tolerance tests were performed in all individuals to diagnose IFG, IGT and DM. Associations were investigated using multivariate logistic regression using SPSS Version 10.0. RESULTS: In the present study, the prevalence of diabetes in Raica community consuming camel milk (RCCM, n=501) was 0%; Raica community not consuming camel milk (RCNCM, n=554) was 0.7%; non-Raica community consuming milk (NRCCM, n=515) was 0.4% and non-Raica community not consuming camel milk (NRCNCM, n=529) was 5.5%. Stepwise logistic regression analysis showed that consumption of camel milk was statistically highly significant as protective factor for diabetes. Multiple logistic regression analysis revealed that camel milk consumption and community factor were associated with decreased prevalence of diabetes. CONCLUSION: Camel milk consumption and lifestyle have definite influence on prevalence of diabetes. Hence, adopting such life pattern may play protective role in preventing diabetes to some extent.

Prevalence of rheumatic heart disease in school children in Bikaner: an echocardiographic study.

OBJECTIVE: To determine prevalence of rheumatic heart disease (RHD) using clinical and echocardiographic criteria and to study influence of socioeconomic status (SES) we studied school children in a north-western Indian town. METHODS: 3292 school children, age range 5-14 years, in two private schools, ten middle SES government schools and six low SES government schools were invited to participate in the study. 3002 (1837 boys, 1165 girls) were clinically examined (response 91%) of which 1042 were in private schools, 1002 in middle SES schools and 958 in low SES schools. Prevalence of cardiac murmurs and RHD based on clinical diagnosis was determined in school by a trained team of physicians. Those with a murmur were further evaluated by Doppler-echocardiography in the hospital. Group-specific and age-specific rates (prevalence/thousand) of murmurs and cardiac lesions were determined. RESULTS: A significant cardiac murmur was observed in 55 subjects (18.3/1000) with similar prevalence in boys (20.7) and girls (14.6). The prevalence of murmur was significantly greater in children belonging to low SES schools (29.2/1000) as compared to middle SES (18.9) and higher SES schools (7.6). RHD prevalence based on clinical diagnosis was observed in 50 children (16.7/1000) and was similar in boys (19.1) and girls (12.9). Clinical RHD was more in the low SES school children (28.2/1000) as compared to middle (17.0) and high SES schools (5.8). RHD was demonstrated on echocardiography in 2 children (0.67/1000). Other prevalent cardiac lesions were congenital heart disease in 5 (1.66/1000) and mitral valve prolapse in 37 (12.3/1000). CONCLUSIONS: There is a low prevalence of RHD in school children in this region compared to previous Indian studies. Cardiac murmurs are more prevalent among low SES children.

Alcohol and Indian porphyrics.

The role of alcohol as the precipitating factor in the induction of acute attacks of acute intermittent porphyria was studied in an Indian population. Thirty-four teetotal patients with acute intermittent porphyria, in remission, were given 60 ml of 30% ethanol. Except for two patients, all had negative Watson-Schwartz tests prior to the alcohol. Within 24 hours, the Watson-Schwartz test became positive in 16 of these 32 patients (50%). In 8 out of the 34 patients (23.5%) a clinical attack was precipitated, including both patients who had a positive Watson-Schwartz test prior to the alcohol. It was concluded that alcohol does precipitate an acute attack in a significant percentage of patients of Indian origin with acute intermittent porphyria. Patients already excreting porphobilinogen are at a greater risk of developing an acute attack on alcohol ingestion. This study is the first from India and probably first of its kind to be reported from any country.

Assessment of left ventricular function in chronic severe anaemia. An echocardiographic study.

Left ventricle (LV) performance was assessed by echocardiography (2-D and M-mode) in 30 patients with chronic severe anaemia and an equal number of age and sex matched healthy controls. Patients with anaemia were divided into two groups: those with tachycardia (pulse rate more than 100 per min) and those without. LV performance indices computed were LV ejection fraction (LVEF), % fractional shortening (FS), cardiac index (CI) and stroke volume index (SVI). In patients of anaemia with tachycardia, LVEF was 48.6 +/- 8.41 (mean +/- SEM) vs 71.6 +/- 4.96 among controls. Percentage FS was 19.93 +/- 4.21 vs 36.0 +/- 4.5, CI 5.46 +/- 1.2 vs 3.1 +/- 0.78 l/min/m2, and stroke index 48.6 +/- 12.2 vs 41.5 +/- 10.7 ml/beat/m2. In patients without tachycardia, LVEF was 55.1 +/- 8.86, percentage FS 23.6 +/- 5.42, CI 2.87 +/- 0.526 and stroke index 41.34 +/- 12.1. These findings suggest that LV performance was depressed in both groups of patients with anaemia but LV function was better in patients without tachycardia.

Propranolol in acute intermittent porphyria.

Twenty cases of acute intermittent porphyria were studied during the acute phase. Cardiovascular manifestations were noted in all the cases, with tachycardia in 20 and with hypertension in 17. Propranolol in doses ranging from 20--200 mg was given to all the cases and produced adequate control of tachycardia and hypertension. At follow-up, smaller doses of propranolol were found to maintain the pulse rate and BP within normal limits and also to prevent acute attacks.
