abstract

sulphur mustard is a chemical warfare agent, which was largely used during the world war one and in iraq-iran conflict. it may also be used as a chemical terrorism agent. therefore, medical professions should have sufficient knowledge and be prepared for medical intervention of any such chemical attack. sulphur mustard exerts direct toxic effects on the eyes, skin, and respiratory tract, with subsequent systemic actions on the nervous, immunologic, hematologic, digestive, and reproductive systems. it is an alkylating agent that affects dna synthesis and thus, delayed complications have been considered since the world war one. cases of malignancies in the target organs particularly in hematopoietic, respiratory, and digestive systems were reported. common delayed respiratory complications include chronic bronchitis, bronchiectasis, frequent bronchopneumonia, and pulmonary fibrosis, all of which tend to deteriorate with time. severe dry skin, delayed keratitis, and reduction of natural killer cells with subsequent increased risk of infections and malignancies are also among the most distressing long-term consequences of sulphur mustard intoxication. however, despite extensive research that has been conducted on iranian veterans during the past decades, major gaps continue to remain in the sulphur mustard literature. immunological and neurological dysfunctions and the relationship between exposure to sulphur mustard and mutagenicity, carcinogenicity, and teratogenicity are important fields that require further studies, particularly on iranian veterans with chronic health problems caused by sulphur mustard poisoning. there is also a paucity of information on the medical management of acute and delayed toxic effects of sulphur mustard poisoning, a subject that greatly challenges the medical professions.

Evaluation of JAK2 (V617F) Mutation in Iranian Veterans with Delayed Complications of Sulphur Mustard Poisoning

Background: Sulfur mustard was the most widely applied chemical warfare agent by the Iraqi army in Iran–Iraq war (1983-1988). Considering the role of sulfur mustard toxicity in hematopoietic neoplasms and also new role of JAK2 mutation in these neoplasms, we assessed this mutation and delayed hematologic complications in veterans exposed to sulfur mustard. Methods: This case control st...

Delayed neurological complications of sulphur mustard and tabun poisoning in 43 Iranian veterans.

Delayed neurotoxic complications of chemical warfare agents (CWA), such as sulphur mustard (SM) and tabun, in human beings have not been reported in detail. We thus aimed to investigate possible neurotoxic complications of these agents in Iranian veterans 22-27 years after exposure. After co-ordination with the veteran foundation and obtaining the approval of the medical research ethics committ...

HEMATOLOGICAL FINDINGS OF SULPHUR MUSTARD POISONING IN IRANIAN COMBATANTS

Sulphur mustard (SM) is an alkylating agent that was first used as a chemical warfare agent during the First World War in 1917. SM is readily absorbed from the skin, respiratory and gastrointestinal tract and is distributed to several organs. SM may act rapidly and persistently upon DNA replicating mechanism of the individual cells during mitosis particularly in the hematopoietic system. O...

Long-term complications of sulfur mustard poisoning: retinal electrophysiological assessment in 40 severely intoxicated Iranian veterans

BACKGROUND The eye is one of the most sensitive organs to sulfur mustard (SM) [C4H8Cl2S], and preliminary symptoms of exposure usually become evident in the eyes. In this study we aim to evaluate the possible long-term retinal electrophysiologic complications of SM poisoning in Iranian veterans during Iran-Iraq war (1980-1988). METHODS In a cross-sectional study forty Iranian veterans who wer...
