Sera from 25 patients with type 1 (Lepra), upgrading and downgrading, and type 2 (erythema nodosum leprosum [ENL]) reactions were assayed, during the reaction and after its clinical remission, for changes in levels of alpha-1-antitrypsin (A1A) and C-reactive protein (CRP). The results were compared with those from normal healthy adults and patients of leprosy without history and/or clinical evidence of reaction. The A1A levels correlated better with changes in status of type 1 reaction; whereas CRP levels correlated well with alterations in type 2 reactions and were definitely superior to A1A in this situation for monitoring the course of these episodes.
Twenty-five patients with Type I (lepra) and Type 2 (ENL) reactions, were assayed for SIL-2R in serum-before and after treatment for their acute condition-and the results were compared with 10 normal healthy adults and 20 patients of leprosy per se. Classification of each subject into different leprosy groups, and into various types and subtypes of reactions, was done according to standard criteria, prior to inclusion into the study. Detailed statistical evaluation of the data revealed significantly higher levels of SIL-2R in all leprosy patients, as compared to normal controls, with higher levels in the multibacillary groups as compared to the paucibacillary group. SIL-2Rs appeared higher in Type I upgrading reaction than in other fo rms of reaction, though this was not statistically significant. There was no significant change in levels fo llowing treatment and clinical remiSSIOn. 'Soluble' interleukin-2 receptors (SIL-2R), are part of the alpha polypeptide subunit (55 Kd) with low affinity to IL-2, that are released from the cell membrane of activated immunocompetent cells under certain conditions, in vitro l and in vivo. 2 .3 The role of this molecule in modulation of immune mechanisms is still unsettled although its 'potential' in down-regulating immune activation is well recognized.4 In addition to malignancies,3 AIDS5 and autoimmune diseases, SIL-2R has been studied in leprosy patients per se with intriguing findings.6,7 The SIL-2R values were raised across the spectrum and did not vary significantly between the various clinical bacilliferous groups, while paucibacillary cases had significantly different values, fa lling somewhere between that of the normal healthy adults and the multibacillary clinical groups. However, in a few patients who were
Twenty-five patients with type 1 (lepra) and type 2 (E.N.L.) leprosy reactions were studied for lymphocyte adenosine deaminase activity (L-ADA), during and after treatment of the reactions, using a standard technique, in order to establish its pattern and if possible, its value in assessing the course of reactions. The results were compared with those from 30 control subjects, comprising 10 normal healthy adults, 10 patients with borderline tuberculoid (BT) leprosy, four patients with borderline lepromatous (BL) leprosy and six patients with lepromatous (LL) leprosy. The level of L-ADA in the leprosy controls was higher than that of normal healthy subjects. The L-ADA values in patients with different types of reactions were about 10-fold higher than those obtained from leprosy controls, emphasizing a possible role in assessing reactions in leprosy. However, there was no significant variation in L-ADA levels, either between the various leprosy controls or reaction groups, before and after treatment.
Background: The genetic factors play an essential role in the cell behavior and function in areas affected with cancer, identifying them could help faster risk detection and mitigation of cases that can be easily saved without much therapeutic intervention at the primary stage itself. This review aims to develop comprehensive evidence regarding genomics in oral cancer initiation, regulation, and progress/inhibition. Material and Methods: A systematic review was carried out of all the reported literature on genomics and proteomics as biomarkers from January 2015 to December 2021 across 3 different search engines- Medline/PubMed, Google Scholar and Scopus. There were 61 articles for the genetic components of oral cancer after following the PRISMA guidelines. Results: Among the 61 articles a number of genes were identified which showed either over or under expression in presence of cancer. All of the proteins showed a rise in their levels in cancer cases compared to healthy cohorts and premalignant cases. The levels of these proteins were also raised significantly in the premalignant cases compared to the healthy patients. Conclusion: A conclusion can be drawn that not all gene markers are raised; some show low expressions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
