A locally developed snakebite management protocol significantly reduces overall anti snake venom utilization in West Bengal, India

OBJECTIVE

The purpose of this study was to determine the impact of a nationally developed snakebite treatment protocol on the amount of anti snake venom (ASV) used in treating snakebites in a developing country and its effect on mortality. In addition, basic epidemiology data were collected and analyzed.

METHODS

Experts in Indian snakebites developed a protocol specifically designed for snakebite treatment in India. A training program was implemented in Midnapore Medical College in West Bengal, India, under the direction of the Health Minister to train care providers in the new protocol. After training, data were collected for 839 snakebite victims over a 12-month period and included epidemiological data, ASV volumes administered, and mortality. The results were collated and compared with results calculated from 780 snakebite victims treated during the 12-month period before implementation of the protocol. Treatment prior to protocol implementation was based on knowledge gained by the care providers from western and forensic medicine textbooks.

RESULTS

Protocol-guided treatment resulted in a 66% decline in the amount of ASV administered to victims. Fewer victims received ASV based on rational guidelines for assessing envenomation, dosage and repeat dosage, and clear endpoints to ASV therapy. In addition, there was a trend towards reduced mortality and an absolute reduction of 24%.

CONCLUSION

Use of the protocol reduced ASV utilization and the number of deaths. Locally developed protocols should be encouraged by such organizations as the World Health Organization and national and state governments and should be established with significant input from local experts.

A study on dyslipidaemia in subclinical hypothyroidism

Subclinical hypothyroidism is characterised by elevated serum thyroid stimulating hormone (TSH) concentrations in association with normal free thyroid hormones. The aim of the study was to evaluate the prevalence and pattern of serum lipid alterations in patients with stable subclinical hypothyroidism in comparison to age- as well as sex-matched euthyroid group and also subgroup analysis between them in regard to age of presentation, sex, antithyroperoxidase (anti TPO) positivity, and TSH value. In this study, 100 patients of SCH were recruited, age ranged 17-68 years, majority (78%) being females, presenting mainly with non-specific symptoms and compared with 52 euthyroid control regarding lipid parameters. Of the subclinical hypothyroidism patients, only 10% had goitre and anti TPO was positive in 52% cases. Serum lipoprotein (a) above the age of 20 years, and total cholesterol, triglyceride and low density liporpotein cholesterol in the age group of 40-50 years were significantly elevated. In addition, total cholesterol, triglyceride and low density lipoprotein cholesterol levels in anti TPO positive cases and serum triglyceride and low density lipoprotein cholesterol in anti TPO negative patients showed statistically significant higher levels. In males only lipoprotein (a), but in females total cholesterol, triglyceride, low density lipoprotein cholesterol and liproprotein (a)--all were significantly elevated.
