Popis: This case report presents two males with drug-induced liver injury acquired from working at a glass factory dealing with silica and 2,2-dichloro-1,1,1-trifluoroethane (HCFC-123). Within one month of work, both patients presented with fever, icterus with liver dysfunction, and eosinophilia. Case 1 had experienced recurrence of symptoms twice while working and showed positive results for the drug-induced lymphocyte stimulation test (DLST). Meanwhile, case 2 was diagnosed by liver biopsy and clinical course but was negative for DLST. Hazard of exposure to non-crystalline silica is low, but drug-induced liver injury after exposure to HCFC-123 has been reported. Allergic liver injury is also caused by chemical substances;however, the insight into whether this injury is caused by exposure to silica or HCFC-123 remains unclear. Further studies are required to examine the influence of silica and HCFC-123 on drug-induced liver injury among glass-factory employees.
