Following a three-week administration of alpha-interferon (IFN-alpha), a 62-year-old woman with chronic hepatitis C manifested fever and dyspnea and showed diffuse infiltrative opacities on chest roentgenograms. Her laboratory data included results of anemia with reticulocytosis, a decreased complement level and hepatitis with elevated ALP, LDH and gamma-GTP. Because laboratory data also revealed a positive lymphocyte stimulation test for IFN-alpha, this cytokine was considered to be responsible for the development of interstitial pneumonia, hemolytic anemia and cholestatic liver dysfunction due to its immunomodulatory effects. Although these three disorders have been reported to develop singly after IFN-alpha therapy, this is the first report of a patient in whom these disorders occurred simultaneously.

Evaluating potential adverse health impacts caused by pesticides is an important parameter in human toxicity. This study focuses on the importance of subchronic toxicity assessment of cymoxanil fungicide in rats with special reference to target biochemical enzymes and histopathological changes in different tissues. In this regard, a 21-day toxicity study with repeated cymoxanil oral doses was conducted. It has been shown that low doses (0.5 mg/kg) were less effective than medium (1 mg/kg) and high (2 mg/kg) doses. Moreover, high dose dose-treated rats showed piecemeal necrosis in the liver, interstitial nephritis and tubular degeneration in the kidneys, interstitial pneumonia and type II pneumocyte hyperplasia in the lungs, gliosis, spongiosis, and malacia in the brain, and testicular edema and degeneration in the testes. Cymoxanil significantly increased AST, ALT, and ALP in serum and liver, indicating tissue necrosis and possible leakage of these enzymes into the bloodstream. Creatinine levels increased, indicating renal damage. Similarly, significant inhibition was recorded in brain acetylcholinesterase, indicating that both synaptic transmission and nerve conduction were affected. Importantly, these histopathological and biochemical alterations were dose-dependent. Taken together, our study reported interesting biochemical and histopathological alterations in different rat tissues following repeated toxicity with oral doses of cymoxanil. Our study suggests future studies on different pesticides at different concentrations that would help urge governments to create more restrictive regulations concerning these compounds' levels.
