Paraquat poisoning is very severe. Most victims, including those who have ingested a small amount, will die from Paraquat poisoning. The cause of death in the majority of such cases is lung fibrosis. Paraquat poisoning in patients with positive human immunodeficiency virus (HIV) infection status has seldom been reported. Herein, we report a case of an HIV patient with Paraquat poisoning who had an excellent outcome even without standard treatment. Currently, only 3 such cases have been reported in the literature and in each case there was a good outcome, which was not expected according to predictive models. A possible mechanism may involve the relative lack of functional macrophages in HIV patients, which would tend to result in much less severe lung injury. None of the available predictive models of Paraquat poisoning appear to be appropriate for HIV patients.Paraquat poisoning in HIV patients may have better survival due to less lung injury.
Extranodal natural killer (NK)/T-cell lymphoma, nasal type (ENKTLN), is characterized by higher prevalence in East Asians and South Americans, association with Epstein-Barr virus infection, aggressive nature in most cases, and resistance to conventional treatment strategies such as chemotherapy and radiotherapy. The optimum treatment for this disease has not yet been established. We report a successful treatment experience in a case of ENKTLN, with a combination regimen including interferon-alpha, corticosteroid and narrowband ultraviolet B, which may serve as a promising therapy for this aggressive disease at earlier stages.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
