ABSTRACT

Background: Delusional parasitosis (DP) is characterized by single hypochondriacal delusion in which patient feels he/she is infested with insects. In India, many patients present with the sensation of something crawling on their skin. However, these patients are not delusional and often respond to medicines other than anti-psychotics. Methodology: An interventional study was carried out on patients on OPD basis. Co-morbid psychiatric illness was analyzed and patients started on anti-depressant or anti-psychotics and effectiveness of the treatment were noted. A total of 45 patients were enrolled in the study over a 3 month period. Results: Out of the total 45 patients, 73% were females. Daily activity was mildly affected in 33% and moderately affected in 27% respectively. 27% patients had psychotic disorders, somatoform disorders and history of nicotine abuse each. 33% patients went to dermatologist first. For psychiatric intervention, 80% patients started on anti-depressants and 20% on anti-psychotic. By end of 2 weeks, 40% patients reported at least 50% amelioration in symptoms. 80% patients had significant recovery by 4 weeks. Conclusion: Delusional parasitosis is considered as a severe form of delusional disorder in western literature, However, in developing countries like India, an expression of something crawling on skin is often a somatoform presentation rather than delusional. It needs to be identified as such and given proper treatment.
