Pemphigus Oral Lesions Intensity Score (POLIS): A Novel Scoring System for Assessment of Severity of Oral Lesions in Pemphigus Vulgaris.

ABSTRACT: Background: Many patients with pemphigus vulgaris (PV) in India present with predominant/exclusive oral mucosal lesions. Current validated scoring systems for pemphigus do not adequately represent the clinical variability of oral lesions. Objective: To develop and validate a novel scoring system exclusively for oral lesions in PV. Methods: In this cross-sectional study, the Delphi method was used to build an initial scale that was administered in 115 patients with PV. Exploratory factor analysis was used to examine the underlying factor structure of the new scale. The psychometric properties of the new scale were studied. Correlations between the new scale and Autoimmune Bullous Skin Disorder Intensity Score (ABSIS), Pemphigus Disease Area Index (PDAI), and Physician Global Assessment (PGA) were also assessed. Results: Content validity of the initial scale was established with an average content validity index (CVI) of 0.8. Exploratory factor analysis resulted in a 3-factor structure with a total of 9 items. Corrected item-total correlation, a measure of data quality, was more than 0.30 for all items in the new oral mucosal scale-Pemphigus Oral Lesions Intensity Score (POLIS). Significant correlations were observed between POLIS and oral ABSIS (r = 0.85, p < 0.001), mucosal PDAI (r = 0.70, p < 0.001), and PGA (r = 0.60, p < 0.001). POLIS was also reliable with good internal consistency (Cronbach's ? = 0.86) and strong inter-rater agreement. Limitations: The study cohort included participants from a single center. Usability and time taken to administer the scale were not assessed. Conclusions: The new scale, POLIS, has adequate validity and reliability. It includes both quality of life and clinical disease severity parameters, assessing disease severity holistically. Further studies evaluating the scale's responsiveness to change are in progress.

Project description:Importance:The variation in both clinical appearance and responses to diverse treatment options emphasize the importance of an accurate, clinically relevant, yet easy-to-use scoring system in hidradenitis suppurativa. Objective:To propose and provide validation data for the newly designed Severity Assessment of Hidradenitis Suppurativa score. Design, Setting, and Participants:We prospectively assessed disease severity using Hurley staging and the modified Hidradenitis Suppurativa Score in 355 patients referred to Ruhr-University Bochum Department of Dermatology between March 2016 and June 2017. We also assessed disease severity via the Severity Assessment of Hidradenitis Suppurativa score. Main Outcomes and Measures:Evaluation and assessment of convergent validity and responsiveness to treatment of the Severity Assessment of Hidradenitis Suppurativa score. Results:Eighty-eight of the 355 patients (134 [37.7%] men and 221 [62.3%] women with a median [IQR] age of 40 [30-49] years) were classified as Hurley stage I, 221 were Hurley stage II, and 46 were Hurley stage III, with an overall median modified Hidradenitis Suppurativa Score of 31 (interquartile range [IQR], 19.3-53). The median total Severity Assessment of Hidradenitis Suppurativa score was 6 (IQR, 4-9), significantly different among the 3 Hurley groups. The median SAHS score for patients in Hurley stage I was 5 (IQR, 3-6), 6 (IQR, 5-9) for patients in Hurley stage II, and 9 (IQR, 7-12) for patients in Hurley stage III (P?<?.001, Kruskal-Wallis test). Correlation analysis showed a significant correlation between the modified Hidradenitis Suppurativa Score and the Severity Assessment of Hidradenitis Suppurativa score (r?=?0.79, P?<?.001). Disease severity assessment before and after 3 months of conservative systemic treatment showed a significant correlation between the Severity Assessment of Hidradenitis Suppurativa score and modified Hidradenitis Suppurativa Score. Both the mHSS (P?=?.001) and the SAHS score (P?<?.001) significantly differed between the baseline visit (median mHSS, 33 [IQR, 24-52]; median SAHS score, 6 [IQR, 5-9]) and the 3-month visit (median mHSS, 28 [IQR, 15-43.5]; median SAHS score, 5 [IQR, 4-6.3]). The 2 patient-reported items demonstrated excellent test-retest reliability with intraclass correlation coefficient values greater than 0.8. Conclusions and Relevance:Our validation data demonstrated that the Severity Assessment of Hidradenitis Suppurativa score is a disease severity instrument that significantly correlates with Hurley staging and the modified Hidradenitis Suppurativa Score, and is responsive enough to measure treatment outcome.

Project description:BACKGROUND:Severity of AP is an important indicator of death rate, playing a crucial role in defining a correct dealing with a patient at his/her initial admission, in deciding on the need to transfer a patient to the intensive care unit. Many studies point out a direct relation between the death rate and the number of affected organs. In light of this, looking for the new criteria of multiple organ failure is still useful in clinical practice. Typically, assessment of multiple organ failure with patients undergoing treatment in the intensive care unit is carried out with the use of various integrated scores based both on clinical laboratory assessment of patient's condition and on data obtained by advanced imaging methods. However, many scientists point out that the facilities of diagnostic radiology, including in particularly computerised tomography, are not used to the full extent. AIM:We developed a CT score for assessment of pancreatitis severity that takes into consideration not only alterations of the pancreas but also enables evaluation of multiple organ failure with the examined patients. METHODS:We have examined 100 patients with suspected pancreatitis. Among them 30 patients had pancreatitis without alterations of the vital organs; 70 patients had alterations of the vital organs, suffered organ or multiple organ failure and received treatment in the surgery unit and intensive care unit of the Department of Surgical Conditions of Karaganda Medical University. RESULTS:Because of CT results, based on the proposed score, we assessed a degree of pancreas necrosis, analysed the relation between organ failure and degree of pancreas necrosis. Finally, we evaluated the connection between multiple organ failure and the specific failure of one organ and the presence of necrosis and death rate. CONCLUSION:The proposed score for CT-based assessment of pancreatitis severity can be used not only for identification but also for prediction of organ failure at the early stage of pancreatitis to a high accuracy as compared to conventional CT systems for assessment of the condition of patients affected by pancreatitis. It can also be used to differentiate the severity of organ failure and the number of affected organs.

Project description:Neonatal disease severity scoring systems are needed to make standardized comparison between performances of different units and to give prognostic information to parents of individual babies admitted. Existing scoring systems are unsuitable for resource-limited settings which lack investigations like pH, pO2/FiO2 ratio, and base excess. This study was planned to evaluate Modified Sick Neonatal Score (MSNS), a novel neonatal disease severity score designed for resource-constrained settings. It was a facility-based cross-sectional analytical study, conducted in the "Special Newborn Care Unit" (SNCU) of government district hospital, attached to Kasturba Medical College, Mangalore, India from November 2016 to October 2017. A convenience sample of 585 neonates was included. Disease severity was assessed immediately at admission using MSNS. MSNS had 8 parameters with 0, 1, and 2 scores for each. 41% of study population was preterm (n=240), and 84.1% had birth weight less than 2500 grams (n=492). The mean (SD) of the total MSNS scores for neonates who expired and discharged was, respectively, 8.22 (2.96) and 13.4 (2.14), a difference being statistically significant at P < 0.001. Expired newborns had statistically significant frequency of lower scores across each of the parameters. An optimum cutoff score of ≤10 with 80% sensitivity and 88.8% specificity in predicting mortality was obtained when the ROC curve was generated with the MSNS score as the test variable. Area under the curve was 0.913 (95% CI: 0.879-0.946). In conclusion, MSNS is a practicable disease severity score in resource-restricted settings like district SNCUs. It is for application in both term and preterm neonates. Total score ≤10 has a good sensitivity and specificity in predicting mortality of admitted neonates when used early during the course of hospitalization. MSNS could be used as a tool to compare performance of SNCUs and also enable early referral of individual cases to units with better facilities.

Project description:BACKGROUND: A number of autoimmune diseases have been clinically and pathologically characterized. In contrast, target antigens have been identified only in a few cases and, in these few cases, the knowledge of the exact epitopic antigenic sequence is still lacking. Thus the major objective of current work in the autoimmunity field is the identification of the epitopic sequences that are related to autoimmune reactions. Our labs propose that autoantigen peptide epitopes able to evoke humoral (auto)immune response are defined by the sequence similarity to the host proteome. The underlying scientific rationale is that antigen peptides acquire immunoreactivity in the context of their proteomic similarity level. Sequences uniquely owned by a protein will have high potential to evoke an immune reaction, whereas motifs with high proteomic redundancy should be immunogenically silenced by the tolerance phenomenon. The relationship between sequence redundancy and peptide immunoreactivity has been successfully validated in a number of experimental models. Here the hypothesis has been applied to pemphigus diseases and the corresponding desmoglein autoantigens. METHODS: Desmoglein 3 sequence similarity analysis to the human proteome followed by dot-blot/NMR immunoassays were carried out to identify and validate possible epitopic sequences. RESULTS: Computational analysis led to identifying a linear immunodominant desmoglein-3 epitope highly reactive with the sera from Pemphigus vulgaris as well as Pemphigus foliaceous. The epitopic peptide corresponded to the amino acid REWVKFAKPCRE sequence, was located in the extreme N-terminal region (residues 49 to 60), and had low redundancy to the human proteome. Sequence alignment showed that human desmoglein 1 and 3 share the REW-KFAK-RE sequence as a common motif with 75% residue identity. CONCLUSION: This study 1) validates sequence redundancy to autoproteome as a main factor in shaping desmoglein peptide immunogenicity; 2) offers a molecular mechanicistic basis in analyzing the commonality of autoimmune responses exhibited by the two forms of pemphigus; 3) indicates possible peptide-immunotherapeutical approaches for pemphigus diseases.
