Researchers are making all out efforts worldwide, to find a serological marker to monitor the disease severity and/or measure efficacy of the drug. There are many potential molecular targets being investigated as a candidate marker. However, till date there has been no significant breakthrough. Thus, various scoring systems have been devised to evaluate the disease severity in psoriasis. In spite of constant revisions of the scores being currently used, from time to time. None of the scores yet satisfy all the validation criteria desired of an ideal scoring system. And this is partly also because of the fact that the psoriasis has such a huge range of clinical variants. Nevertheless, in the recent past, significant progress has been made in this direction.
