They are elevated in conditions like infections, malignancies, mental illness and drug reactions among others. Aim The study aimed at identifying the IMs that reflect the severity and recovery in severe cutaneous adverse drug reactions (SCARs). Methods A cross-sectional observational study was conducted among patients with SCARs (Stevens Johnson syndrome [SJS]/ toxic epidermal necrolysis [TEN] and drug reaction with eosinophilia and systemic symptoms [DRESS]) admitted to a tertiary care hospital over 18 months. Results Twenty SJS/TEN and 8 DRESS cases were included in the study. There were more females in the study (F: M = 2:1). Comparing the IMs of SJS/TEN and DRESS revealed that most markers on day 7 were lower as compared to day 0. There was a significant difference in eosinophil count (EC), procalcitonin (PCT) (p-value <0.05), and recovery time between the two groups. In the SJS/TEN group, markers like ferritin (>2000 ng/mL) and PCT (>2.0 ng/mL) were significantly higher, around the septic range, in patients with concurrent connective tissue disease and culture positivity. Ferritin (p-value- 0.025, rho- 0.578), PCT (p-value- 0.013, rho- 0.239), and ESR (p-value- 0.041, rho- 0.482) were associated with the severity of SJS/TEN. Patients with DRESS had an early recovery with a statistically significantly shorter hospital stay than SJS/TEN (p<0.005). Baseline severity-of-illness score for TEN levels, total counts, and day 7 PCT significantly reflected the time taken for recovery. Limitations Marker analysis was performed at baseline and on day 7 of admission, but not after complete clinical recovery, therefore indicating a trend but limited conclusive behaviour of markers at the time of recovery. Conclusion The progression of IMs in a SCAR follows the clinical course of the illness. IMs like ferritin and PCT, along with routine haematological investigation, aid in identifying the severity, differentiating it among patients with comorbidities, and helping predict the recovery time in SCARs.</p>","PeriodicalId":50376,"journal":{"name":"Indian Journal of Dermatology Venereology & Leprology","volume":" ","pages":"1-9"},"PeriodicalIF":3.2,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144530848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors explore the pivotal role of dermatologists in the multidisciplinary approach to CSA, emphasising their involvement in history-taking, physical examination, injury interpretation, and forensic evidence collection. The article also discusses the importance of timely reporting to authorities and adhering to treatment protocols based on the prevalent guidelines. This article attempts to create awareness among practising dermatologists in India about their role in the early detection and comprehensive care of CSA survivors.

Aim The aim of this study was to observe the effect of exposure to pesticides (by blood pesticide levels) on serological markers of pemphigus (anti-Dsg1, anti-Dsg3, and anti-M3 ACh receptor antibodies) amongst healthy individuals involved in pesticide use. Methods This was an observational, cross-sectional pilot study performed in Punjab. The study subjects were 45 couples (husband and wife) wherein the husband was involved in activities like spraying and handling pesticides, and the wife was considered a non-genetically related control (not occupationally exposed to pesticides). Clinical data were collected by a structured questionnaire, and venous blood was collected to test blood pesticide levels. Gas chromatography - mass spectroscopy (GC-MS) and enzyme-linked immunosorbent assay (ELISA) were used for anti-Dsg-1, anti-Dsg-3, and anti-M3Ach receptor antibody level detection. Results Pesticides were detected in both husband and wife. There was no correlation between the duration of pesticide exposure and their blood levels. Chlorpyrifos was most frequently detected in husbands and β- endosulfan in wives. The levels of anti-Dsg-1 and anti-Dsg-3 titres were below the diagnostic cut-off values (20 RU/mL) for pemphigus in all participants. Husbands had significantly higher anti-Dsg3 values (p=0.029). There was no statistically significant association between the presence of pesticides and anti-Dsg-1, anti-Dsg-3, and anti-M3 ACh receptor antibodies in the sera. Anti-Dsg-1 antibodies had a significant positive correlation with chlorpyrifos serum levels (r= 0.3, p=0.005). Limitation Determining aspects like expression of adhesion proteins on keratinocyte cell lines, long term follow up of healthy subjects and correlation with pesticide levels with cases of pemphigus was not done as it is cost intensive. Conclusion The exposure to pesticides did not significantly increase any of the biomarkers above clinical cut-off levels in any of the healthy participants. Considering the rarity of clinically manifest pemphigus, many healthy subjects need to be studied with the current study design. Alternatively, the expression of adhesion proteins or their adhesion function can be assessed in keratinocyte cell lines upon incubation with varying concentrations of pesticides.</p>","PeriodicalId":50376,"journal":{"name":"Indian Journal of Dermatology Venereology & Leprology","volume":" ","pages":"1-6"},"PeriodicalIF":3.2,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144530856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
