title: Postpartum thyroiditis in India: prevalence of postpartum thyroiditis in Kashmir Valley of Indian sub-continent.
abstract: Various studies have reported a spectrum of thyroid dysfunction in the postpartum period. Postpartum thyroiditis is a syndrome of thyroid dysfunction that occurs in the first year after parturition. Prevalence of postpartum thyroiditis has been reported to vary from 3 to 6 percent in different regions of the world. Kashmir Valley is inhabited by a relatively homogeneous racial group and the Valley has been documented to have significant iodine deficiency. We studied the prevalence and pattern of postpartum thyroiditis in an urban region of this Valley. 120 women were registered within first month of postpartum period for the study along with one hundred controls. Of these 120 women, 104 reported for follow-up at 3 months postpartum and 106 reported for follow-up at 6 months postpartum. Initial and subsequent clinical details at follow-up were recorded on a pre-determined questionnaire. Overall, postpartum thyroiditis (PPT) was seen in 8 (7%) study subjects. Of these 8 patients with PPT, 4 had biochemical evidence of thyrotoxicosis at first month, 3 developed biochemical thyrotoxicosis at 3-month follow-up while as one study subject developed thyrotoxicosis at 6 months. Most of these subjects were antithyroid antibodies (anti-microsomal and anti-thyroglobulin) positive. We conclude that iodine deficient status of the community doesn't seem to influence the incidence of PPT.
