DRESS is one of the most severe drug reactions. The aim of this retrospective study was to summarize the clinical presentation, genetic predisposition and prognostic factors of DRESS. A total of 52 patients with DRESS, who were inpatients at a medical referral centre in Shanghai, China, from January 2011 to December 2016, were analysed retrospectively. All the patients had skin eruption, 83% had liver involvement, and ≤10% had other organ involvement. Average cost of hospitalization was $5,511±3,050. The 3 most common causative agents were allopurinol (18/52; 35%), salazosulphapyridine (11/52; 21%) and carbamazepine (5/52; 10%)...

REVIEW
Zhi-Hua Xing, Yu-Chang Ma, Xin-Ping Li, Bing Zhang, Meng-di Zhang
The research progress of puerarin and its derivatives in anti-inflammatory and anti-gout activities was reviewed in this paper. Puerarin possesses anti-inflammatory activity by affecting immunocyte, inflammation cytokines and signaling pathway. Puerarin also has anti-gout activity through inhibition of xanthine oxidase, promoting the excretion of uric acid to reduce serum uric acid level. Although its ability in reducing uric acid level was lower than that of allopurinol in clinical application, puerarin can also enhance the total antioxidant and free radical scavenging with stronger anti-inflammatory effect, so it will be a promising research direction to find new drugs with better anti-gout activity and less side effects by modifying the chemical structure of puerarin...

Tumor lysis syndrome is a metabolic complication that may follow the initiation of cancer therapy. It commonly occurs in hematological malignant patients particularly non-Hodgkin's lymphoma and acute leukemia due to chemotherapy or spontaneously. It is characterized by a biochemical abnormality such as hyperuricemia, hyperkalemia, hyperphosphatemia, and hypocalcemia and its clinical outcome is directly related to these biochemical abnormalities. Prevention and treatment of tumor lysis syndrome depend on immediate recognition of patients at risk...

INTRODUCTION: Topiroxostat, a recently developed xanthine oxidase inhibitor, is expected to have fewer adverse effects than allopurinol because it has different mechanism of action from alloprinol. However, its dosage, usage and safety have not been established in patients with impaired renal function or those undergoing dialysis at the development since no studies was conducted in these patients. METHODS: Cross over clinical trial using 3 months of allopurinol and topiroxostat on 27 maintain Japanese HD patients were carried out...

Toxic epidermal necrolysis (TEN) is a serious adverse drug reaction with high lethality, which usually requires intensive-medical care. A 44-year-old man developed generalized exanthema with increasing exfoliation and mucosal involvement after taking allopurinol, ibuprofen, and etoricoxib. The clinical diagnosis of TEN was histologically confirmed. Prednisolone therapy with 3 mg/kg body weight (BW) was not able to prevent further progress to finally 80% of the body surface, and infliximab 5 mg/kg BW was given as a single dose...

A 71-year-old male, a renal allograft recipient, presented to us with a history of fever and right palm swelling. He had a history of fever 7 years back when he was treated with antitubercular treatment (ATT). Three years back, he was diagnosed to have gout and he was started on allopurinol. He developed severe bone marrow toxicity and allopurinol was changed to febuxostat. On admission, routine investigations did not reveal any focus of infection. The fluid aspirate from the palm revealed acid-fast bacilli (AFB)...

A new agar-free bioautographic assay for xanthine oxidase (XO) inhibitors and superoxide scavengers on TLC layers was developed and validated. Compared to the first version of TLC bioautographic agar overlay method, our bioautographic assay greatly improved the sensitivity and quantification ability. The limit of detection (LOD) of this assay was 0.017ng for allopurinol. Quantitative estimation of XO inhibitors and superoxide scavengers was achieved by densitometry scanning, expressed as allopurinol equivalents in millimoles on a per sample weight basis...

Xanthine oxidase (XO), an enzyme widely distributed among mammalian tissues, is associated with the oxidation of xanthine and hypoxanthine to form uric acid. Reactive oxygen species are also released during this process, leading to oxidative damages and to the pathology called gout. Available treatments mainly based on allopurinol cause serious side effects. Natural products such as flavonoids may represent an alternative. Thus, a series of polymethoxyflavones isolated and hemisynthesized from the bud exudates of Gardenia oudiepe has been evaluated for in vitro XO inhibitory activity...

BACKGROUND: Urate-lowering therapy (ULT) is associated with low rates of adherence, leading to a potential risk of relapse of gouty arthritis, tophi, or urolithiasis. Our main aim was to identify the recurrence of gouty arthritis, tophi, or urolithiasis after discontinuation of ULT. Secondary aims included an assessment of ULT reintroduction rates and factors associated with relapse. METHODS: We conducted a systematic literature review of clinical studies investigating the effect of discontinuing any ULT (allopurinol, febuxostat, probenecid, sulfinpyrazone, benzbromarone) in adults on long-term therapy...

Drug hypersensitivity reactions (DHRs) are unpredictable, complex responses to medicines in predisposed individuals. They represent a major health problem owing to the number of patients affected and the severity of the clinical conditions they can induce. In addition to environmental factors, the underlying mechanisms of DHRs are also influenced by genetic factors, although considerable gaps remain in our knowledge. Therefore, further study of the genetics of DHRs is necessary to shed light on their underlying mechanisms...

Thiopurine drugs, including azathioprine and 6-mercaptopurine, are used commonly in patients with inflammatory bowel disease for maintenance of remission. Although generally well tolerated, adverse effects lead to discontinuation in a significant minority of patients. Pharmacogenomic studies have suggested that metabolic breakdown of azathioprine in an individual is genetically determined. Coupled with the fact that certain thiopurine metabolites, notably 6-thioguanine nucleotide and 6-methylmercaptopurine, are associated with antiinflammatory effects and adverse effects, respectively, some investigators have examined intentionally shunting the metabolism of azathioprine toward increasing 6-thioguanine nucleotide levels by using low doses of the xanthine oxidoreductase inhibitor allopurinol to improve efficacy and decrease toxicity of azathioprine in patients with inflammatory bowel disease...

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are considered a delayed-type hypersensitivity reaction to drugs. They represent true medical emergencies and an early recognition and appropriate management is decisive for the survival. SJS/TEN manifest with an "influenza-like" prodromal phase (malaise, fever), followed by painful cutaneous and mucous membrane (ocular, oral, and genital) lesions, and other systemic symptoms. The difference between SJS, SJS/TEN overlap, and TEN is defined by the degree of skin detachment: SJS is defined as skin involvement of < 10%, TEN is defined as skin involvement of > 30%, and SJS/TEN overlap as 10-30% skin involvement...

OBJECTIVE: Studies found a strong association between allopurinol-induced Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) and the HLA-B*58:01 allele. HLA-B*58:01 screening-guided therapy may mitigate the risk of allopurinol-induced SJS/TEN. This study aimed to evaluate the cost-effectiveness of HLA-B*58:01 screening before allopurinol therapy initiation compared with the current practice of no screening for Malaysian patients with chronic gout in whom a hypouricemic agent is indicated...
