Adverse drug reactions can cause considerable discomfort. They can be life-threatening in severe cases, requiring or prolonging hospitalization, impeding proper treatment, and increasing treatment costs considerably. Although the incidence of severe cutaneous adverse reactions (SCARs) is low, they can be serious, have permanent sequelae, or lead to death. A recent pharmacogenomic study confirmed that genetic factors can predispose an individual to SCARs. Genetic markers enable not only elucidation of the pathogenesis of SCARs, but also screening of susceptible subjects...

Adverse drug reactions (ADRs) affect many patients and remain a major public health problem, as they are a common cause of morbidity and mortality. It is estimated that ADRs are responsible for about 6% of hospital admissions and about 9% of hospitalization costs. Skin is the organ that is most frequently involved in ADRs. Drug-induced skin injuries vary from mild maculopapular eruptions (MPE) to severe cutaneous adverse reactions (SCARs) that are potentially life threatening. Genetic factors have been suggested to contribute to these SCARs, and most significant genetic associations have been identified in the major histocompatibility complex (MHC) genes...

Dapsone has been part of the World Health Organization multidrug therapy for the treatment of leprosy. While it has been efficacious in the management of leprosy, there are many patients who develop adverse drug reactions to the drug including life-threatening reactions such as dapsone hypersensitivity syndrome (DHS). We report a case of a patient who was prescribed dapsone as part of multidrug therapy for leprosy following which she developed DHS. Her condition worsened after tapering the oral steroids given to manage the DHS, and she was detected to have hypothyroidism...

Dapsone-induced hypersensitivity reactions may cause severe cutaneous adverse reactions, such as drug reaction with eosinophilia and systemic symptoms (DRESS). It has been reported that HLA-B*13:01 is strongly associated with dapsone-induced hypersensitivity reactions among leprosy patients. However, the phenotype specificity and detailed immune mechanism of HLA-B*13:01 remain unclear. We investigated the genetic predisposition, HLA-B*13:01 function, and cytotoxic T cells involved in the pathogenesis of dapsone-induced severe cutaneous adverse reactions...

Dapsone hypersensitivity syndrome is a rare yet severe adverse drug reaction caused by dapsone, a principal drug in multidrug therapy for leprosy. HLA-B*13:01 has been identified as a strong risk factor of dapsone hypersensitivity syndrome; however, its low positive predictive value indicated that additional genetic variants may be involved in the disease development. To discover contributing genetic variants within HLA loci in addition to HLA-B*13:01, we performed a high-coverage next-generation sequencing (NGS)-based HLA typing analysis in 103 dapsone-hypersensitive and 857 dapsone-tolerant HLA-B*13:01-positive leprosy patients in a Chinese population...

OBJECTIVES: A previous publication in Chinese leprosy patients showed that the HLA-B*13:01 allele is a strong genetic marker for dapsone-induced drug hypersensitivity reactions, however there are no data describing whether HLA-B*13:01 is a valid marker for prediction of dapsone-induced drug hypersensitivity reactions in other ethnicities or nonleprosy patients. The aim of this study is to investigate whether there is an association between HLA genotypes and dapsone-induced severe cutaneous adverse reactions (SCARs) in Thai nonleprosy patients...

Importance: Pneumocystis pneumonia (PCP) is a potentially lethal opportunistic infection that primary prophylaxis can help prevent. The risk of prophylactic therapy must be weighed against the incidence of PCP in the patient population. Prophylaxis most frequently involves trimethoprim-sulfamethoxazole, with second-line therapies, including atovaquone, dapsone, and pentamide. The indication for prophylaxis in immunocompromised patients without HIV is less well defined. Previously, an incidence of at least 3...

Dapsone-induced agranulocytosis is a rare but potentially fatal adverse drug reaction (ADR). A 45-year-old male Caucasian patient developed agranulocytosis caused by dapsone (diamino-diphenyl sulfone), which he was prescribed for leukocytoclastic vasculitis. Patient's treatment consisted of termination of dapsone, antibiotic therapy, and granulocyte colony-stimulating factor leading to prompt improvement of symptoms and normalization of laboratory blood values. Diagnostic evaluation revealed methemoglobinemia and excluded glucose-6-phosphate dehydrogenase deficiency...

AbstractDapsone is a bactericidal and bacteriostatic against Mycobacterium leprae , a causative agent of leprosy. Dapsone is also applied in a range of medical fields because of its anti-inflammatory and immunomodulatory effects. Dapsone hypersensitivity syndrome (DHS) is a rare yet serious adverse drug reaction (ADR) caused by dapsone involving multiple organs. We performed a systematic review of published articles describing dapsone-induced hypersensitivity syndrome, including all Chinese articles and the latest literature available in online databases published between October 2009 and October 2015...

Many conventional drugs used today, including isoniazid, dapsone, and acetaminophen, are well recognized culprits of hepatotoxicity. With increasing use of complementary and alternative medical therapies, several herbal medicines, such as Ma-Huang, kava, and chaparral leaf, have been implicated as hepatotoxins. Hepatotoxicity may be the most frequent adverse reaction to these herbal remedies when taken in excessive quantities. A myriad of liver dysfunctions may occur including transient liver enzyme abnormalities due to acute and chronic hepatitis...

Adverse drug reactions (ADRs) are a relatively common cause of morbidity and mortality. Many factors can contribute to ADRs, including genetics. The degree to which genetics contributes to ADRs is not entirely clear and varies by drug, as well as the type of ADR. Pharmacogenetics and, more recently, pharmacogenomics have been applied to the field of ADRs for both predictable ADRs and hypersensitivity drug reactions. Evaluations for glucose-6-phosphate dehydrogenase and thiopurine S-methyltransferase are commonplace clinical tests to reduce hematologic problems associated with drugs, such as dapsone and azathioprine, respectively...

Dapsone is a sulfone-type drug used widely for different infectious, immune, and hypersensitivity disorders as an antibacterial treatment alone or in combination for leprosy and sometimes for infected skin lesions. DHS is a severe idiosyncratic adverse reaction with multi-organ involvement. However, acute necrotic hepatitis requiring an emergent LT is rare. Herein, we report a case of 12-yr-old girl who suffered from fulminant hepatitis and multi-organ failure due to DHS for PPD. She was saved by emergent LDLT...
