Diagnostic Signs and Symptoms of Cyanocobalamin Deficiency at Rural Setting in India: Novel Method of Supplementation.

Background: Cyanocobalamin or B deficiency is common in the Indian population, and responsible for anemia. Various clinical manifestations include central nervous system and cardiovascular manifestations, secondary to a rise in serum homocysteine levels.

Method And Patients: In a routine outpatient department at Bawaskar Hospital and Clinical Research Centre, Mahad, patients with suspected clinical signs and symptoms suggestive of cyanocobalamin deficiency were studied in detail regarding their dietary habits, serum hemoglobin, B, and homocysteine levels.

Findings: A total of 1,992 (female 1,009, 50.75%) were clinically examined in detail. Of these, 945 (49.94%), 999 (50.17%), and 48 (2.40%) were strict vegetarians, both vegetarian and nonvegetarian, and strict nonvegetarians, respectively. Common occupations associated with B deficiency include 666 (33.4%) housewives, 396 (19.9%) service workers, 316 (15.9%) businesspeople, 180 (9%), and 198 (9.9%) retired and industrial populations, respectively. Clinical manifestations include recurrent scalp hair loss in 268 (13.5%), poor memory in 240 (12%), tingling and numbness in 200 (10%), and generalized weakness in 387 (19.4%) patients. Additionally, 541 (27.15%) patients had pigmentation of the nail bed, knuckles, oral mucosa, and tongue, while 237 (10.81%) suffered from hypertension and ischemic heart disease. During the process of preparation of vegetarian and nonvegetarian food, there is a 30-48% reduction in vitamin content. Supplementation of vitamin by adding table salt to food on a plate at the time of eating improves the vitamin level in the blood.

Conclusion: In the absence of laboratory investigations in rural settings, clinical signs and symptoms are helpful in detecting B12 deficiency. Directly adding vitamin powder, similar to table salt, to cooked food on the plate improved blood vitamin levels.
