Epidermal necrolysis (EN)--either Stevens-Johnson syndrome (SJS) or toxic EN (TEN)--is a severe drug reaction. We constructed and evaluated a specific algorithm, algorithm of drug causality for EN (ALDEN), in order to improve the individual assessment of drug causality in EN. ALDEN causality scores were compared with those from the French pharmacovigilance method in 100 cases and the case-control results of the EuroSCAR study. Scores attributed by ALDEN segregated widely. ALDEN pointed to a "probable" or "very probable" causality in 69/100 cases as compared to 23/100 with the French method (P < 0.001). It scored "very unlikely" causality for 64% of medications vs. none with the French method. Results of ALDEN scores were strongly correlated with those of the EuroSCAR case-control analysis for drugs associated with EN (r = 0.90, P < 0.0001), with probable causality being reported in 218/329 exposures. ALDEN excluded causality in 321 drugs that the case-control analysis had described as "probably not associated" and in 22/233 drugs that had been described as inconclusive exposures. Being more sensitive than a general method, ALDEN, which correlates well with case-control analysis results, can be considered a reference tool in SJS/TEN.

Analysis of risk factors for adverse drug events in critically ill patients

In everyday clinical practice, almost all physicians come across many instances of suspected adverse cutaneous drug reactions (ACDR) in different forms. Although such cutaneous reactions are common, comprehensive information regarding their incidence, severity and ultimate health effects are often not available as many cases go unreported. It is also a fact that in the present world, almost everyday a new drug enters market; therefore, a chance of a new drug reaction manifesting somewhere in some form in any corner of world is unknown or unreported. Although many a times, presentation is too trivial and benign, the early identification of the condition and identifying the culprit drug and omit it at earliest holds the keystone in management and prevention of a more severe drug rash. Therefore, not only the dermatologists, but all practicing physicians should be familiar with these conditions to diagnose them early and to be prepared to handle them adequately. However, we all know it is most challenging and practically difficult when patient is on multiple medicines because of myriad clinical symptoms, poorly understood multiple mechanisms of drug-host interaction, relative paucity of laboratory testing that is available for any definitive and confirmatory drug-specific testing. Therefore, in practice, the diagnosis of ACDR is purely based on clinical judgment. In this discussion, we will be primarily focusing on pathomechanism and approach to reach a diagnosis, which is the vital pillar to manage any case of ACDR.

Carcinogenesis is a multiyear, multistep, multipath disease of progressive genetic alterations and associated tissue damage. Chemoprevention is the use of drugs or other agents to inhibit, delay, or reverse this process. Despite the enormous population at risk of cancer who would benefit, drug

Colorectal adenomas: a prototype for the use of surrogate end points in the development of cancer prevention drugs.

We examined some of the factors that contribute to the development of adverse drug reactions (ADRs) and analyzed postmarketing ADR reports for 22 drugs. The role of metabolic-based drug-drug interaction in the development of ADRs can not be overstated. Assessment of the postmarketing ADR data for 22 drugs revealed that drugs with high potential for eliciting clinically significant ADRs are usually detected and either withdrawn from the market or placed on restricted use within the first year or two of marketing. Postmarketing data could be a useful tool for understanding the ADR profile of drugs if reporting can be adequately monitored and verified. It is hoped that early evaluation of the clinically meaningful factors such as metabolism, pharmacogenetics, and effect of physiologic and pathophysiologic states on the clinical effect of a drug during drug development would significantly reduce the incidence and severity of post-marketing ADRs.
