Acute Hepatitis in the DRESS Syndrome

Into the storm: the imbalance in the yin-yang immune response as the commonality of cytokine storm syndromes

There is a continuous cycle of activation and contraction in the immune response against pathogens and other threats to human health in life. This intrinsic yin-yang of the immune response ensures that inflammatory processes can be appropriately controlled once that threat has been resolved, preventing unnecessary tissue and organ damage. Various factors may contribute to a state of perpetual immune activation, leading to a failure to undergo immune contraction and development of cytokine storm syndromes. A literature review was performed to consider how the trajectory of the immune response in certain individuals leads to cytokine storm, hyperinflammation, and multiorgan damage seen in cytokine storm syndromes. The goal of this review is to evaluate how underlying factors contribute to cytokine storm syndromes, as well as the symptomatology, pathology, and long-term implications of these conditions. Although the recognition of cytokine storm syndromes allows for universal treatment with steroids, this therapy shows limitations for symptom resolution and survival. By identifying cytokine storm syndromes as a continuum of disease, this will allow for a thorough evaluation of disease pathogenesis, consideration of targeted therapies, and eventual restoration of the balance in the yin-yang immune response.

Identification of novel signal of clobazam-associated drug reaction with eosinophilia and systemic symptoms syndrome: A disproportionality analysis

OBJECTIVES

Clobazam is a well-known benzodiazepine used as an anti-anxiety drug as well as an anti-epileptic, particularly for patients who are not responding to first-line treatments. Recent case reports have indicated the association of clobazam with drug reaction with eosinophilia systemic symptoms syndrome (DRESS Syndrome). However, DRESS syndrome is not known to be associated with clobazam. Thus, the main objective of the current study was to identify the potential signal of clobazam-associated DRESS Syndrome.

MATERIALS & METHODS

US FDA Adverse event reporting system (US FAERS), pharmacovigilance data 2004Q1-2021Q3 was extracted using OpenVigil 2.1-MedDRA-v24. The Proportional Reporting Ratio (PRR), Reporting Odds Ratio (ROR) with a Chi-Square value (95% confidence interval), and number of cases (≥3) were used as disproportionality analysis parameters.

RESULTS

A total of 141 drug-event combinations were reported and results of disproportionality analysis indicate the positive signal of DRESS syndrome with clobazam. The signal strength was decreased after removing the cases of concomitantly administered drugs (phenytoin, levetiracetam, and valproic acid); however, the association of clobazam with DRESS syndrome remains statistically significant. The subgroup analysis results have shown a greater number of cases in the age group (18-64 years) as compared to other age groups whereas the number of cases in the male and female groups is almost similar.

CONCLUSION

The DRESS syndrome is identified as a novel signal with clobazam. However, further causality assessment is required.

Severe DRESS syndrome after carbamazepine intake in a case with multiple addictions: A case report

A case is presented of a male with drug rash with eosinophilia and systemic symptoms (DRESS) syndrome induced by carbamazepine intake. The patient presented all the elements of DRESS syndrome: Skin reaction, fever, enlargement of the lymph nodes, increased eosinophils and lymphocytes, with associated organ dysfunctions. The patient was admitted with acute laryngeal edema and imminence of respiratory insufficiency. The escalation of symptoms for this syndrome is typical, even after the administering of the the culprit medicine has ceased. However, in this case, the most difficult aspect was the complex treatment scheme prior to admission. All medical compounds involved in the background treatment were substituted with other substances in order to control the immune response. Current knowledge regarding DRESS is reviewed and possible influence of various etiologies over the present case are discussed. Clinicians should be aware of this rare situation with life-threatening potential. We benefited from the advantage of reuniting the knowledge of a complex team of experts from various tertiary emergency units in Romania.
