A male patient,51 years old,was diagnosed as follows:① type 2 diabetes mellitus;② grade 2 hypertension(extremely high risk).To improve circulation,the patient was administered pentoxifylline injection 0.2 g mixed with 250 mL of 0.9％sodium chloride injection via an intravenous drip,once daily(qd).After 4 days of treatment,liver function tests showed the following results:alanine aminotransferase(ALT)at 2 390.80 U·L-1,aspartate aminotransferase(AST)at 948.28 U·L-1,and gamma-glutamyltransferase(GGT)at 517.81 U·L-1.It was highly probable that pentoxifylline caused abnormally elevated liver enzymes,with a clear drug-related association.After discontinuing pentoxifylline injection and initiating liver-protecting and en-zyme-lowering treatment,the liver function indicators gradually improved.Enhanced monitoring during the clinical use of pentoxi-fylline is essential to ensure patient safety.

Objective To understand the cases of allergic shock induced by iohexol injection,analyze the characteristics of adverse drug reactions(ADRs),and identify potential influencing factors,ensureing the safety of clinical medication.Methods A literature review and bibliometric analysis were conducted on 23 cases of allergic reactions induced by iohexol injections reported in China from 2010 to 2023.Results Among the cases of allergic reactions induced by iohexol injections,17 cases(73.91% )occurred in males,while 6 cases(26.09% )occurred in females.Individuals aged from 41 to 80 years accounted for a significant proportion(82.61% ).Systemic damage was observed in 8 cases(34.78% ),neurological damage in 7 cases(30.43% ),respiratory and circulatory system damage in 5 cases(21.74% ),and skin and appendage involvement in 3 cases(13.04% ).The majority of allergic reactions had a rapid onset(72.91% ).Patients with pre-existing chronic illnesses and other medical conditions had a higher occurrence rate(82.61% ).Conclusions Iohexol injection can lead to allergic reactions influenced by multiple factors.Healthcare professionals should closely monitor adverse reactions,especially severe ones like allergic shock.
