In clinical practice spectrum of cutaneous reactions to various drugs is a common phenomenon. Drugs usually incriminated are Sulfonamides, Barbiturates, Antitubercular drugs, Antibiotics, Pyrazone derivatives and Non Steroidal Anti-inflammatory drugs [1, 2]. Nitrofurans have been described to cause all types of skin rashes . Any infection and any drug can probably give rise to erythema multiformae . As per best of our knowledge and review of literature including Medline search, erythema multiforme exclusively resulting from administration of Furazolidine has not been reported so far. We present a case of erythema multiforme resulting from administration of Furazolidine.
10 month old child was admitted with rash over lower back, arms, buttocks and thighs. History revealed that the child was having loose motions and vomiting for which she was given Furazolidine (Furoxone) by a private general practitioner.
She reported to us within 10 hours of the administration of the drug with complaints of development of rash and itching. On examination general condition of the child was stable. Pulse rate was 110/min, temperature – 98.6°F. Respiration was 22/min. There were no lesions seen on oral, anal and urogenital mucosa. Skin over buttocks, arms and thighs showed classical “IRIS” lesions of erythema multiforme with dusky centre and bright red raised borders. Palms and soles were spared. Systemic examination was essentially within normal limits. The lesions were confluent at places. There was no conjunctival injection. Furazolidine was stopped and child was treated with antihistaminic and plenty of oral fluids. Skin lesions regressed within 10 days and the child was discharged with the advice not to take Furazolidine in future.
Erythema multiforme (EM), Steven Johnson Syndrome (SJ Syndrome) and Toxic Epidermal Necrolysis (TEN) represent a spectrum of which, EM is the mildest form. Exact etiology of EM is not known, but it is known to occur as an adverse reaction to medications, viral infections, of which Herpes Simplex virus is the most common . Herpes simplex labialis and less commonly HSV genitalis have been implicated in 60% of episodes of EM and are believed to trigger nearly all episodes of EM, frequently in association with sun exposure, despite the presence of robust HSV specific immunity.
The pathogenesis of EM is unclear, but it may be host specific cell mediated immune response to an antigenic stimulus, resulting in damage to keratinocytes. Cytokines released by activated mononuclear cells and keratinocytes may contribute to epidermal cell death and constitutional symptoms .
EM usually has an acute onset and is characterised by target lesions. The lesions may be erythematous, macular, papular, urticarial, vesicular or bullous. These lesions may remain localized to extremities or may become generalized with involvement of oro/genital mucosa and conjunctiva. When mucosal surfaces are involved, it is called as SJ Syndrome and manifests as rhinitis, vulvo-vaginitis and balanitis [7, 9, 10].
Treatment of EM is supportive. Topical emolients, antihistaminic and non steroidal antiinflammatory agents do not alter the course of the disease, but may provide symptomatic relief. Glucocorticoids have no beneficial role in management, rather they may be permissive of HSV replication and make EM episodes more frequent or continuous. Prophylactic oral Acyclovir for 6 months may be effective in controlling recurrent episodes of HSV associated with EM .
Our case did not have any systemic involvement of the mucosal surfaces nor posed any life threatening emergency. The case, however, is being reported for specific association of EM with administration of Furazolidine. Reporting of this case is further considered relevant due to the fact that skin rashes are a very common presentation of many paediatric illnesses and State Consumer Forum has held a Paediatrician negligent for not diagnosing SJ Syndrome, when a child presented with a rash .
