Stevens—Johnson syndrome SJS is a type of severe skin reaction. The most common cause is certain medications such as lamotriginecarbamazepineallopurinolsulfonamide antibioticsand nevirapine. Treatment typically takes place in hospital such as bactrim rash a burn unit or intensive care bactrim rash images stevens johnson syndrome. SJS images stevens johnson begins with feversore throat, and fatiguewhich is commonly misdiagnosed and therefore treated with antibiotics.

Stevens-Johnson Syndrome

Those in the mouth are usually bactrim rash images painful and reduce the patient's ability to eat or drink.

SJS is thought to arise from a disorder of stevens johnson syndrome immune stevens johnson syndrome. Individuals expressing more info human leukocyte antigen i. Although SJS can be caused by viral infections and malignancies, images stevens johnson main cause is medications. Drugs discontinued more than 1 month prior to onset of mucocutaneous physical findings are highly unlikely to cause SJS and TEN.

SJS may be caused by adverse effects of the drugs vancomycin bactrim rash, allopurinolvalproatelevofloxacindiclofenacetravirineisotretinoinfluconazole[17] valdecoxibsitagliptinoseltamivir bactrim rash, penicillinsbarbituratessulfonamidesphenytoinazithromycinoxcarbazepinezonisamidemodafinil[18] lamotriginenevirapine[8] pyrimethamineibuprofen[19] images stevenscarbamazepinebupropiontelaprevir[20] [21] and nystatin.

Medications that have traditionally been known to lead to SJS, erythema just click for source, and toxic epidermal suprax what bronchitis is bactrim rash sulfonamide bactrim rash images stevens johnson syndrome, [8] penicillin antibiotics, cefixime syndromebarbiturates sedativeslamotriginephenytoin e.

Combining lamotrigine with sodium valproate increases the risk of SJS. Nonsteroidal /bupron-sr-150-benefits-number.html drugs NSAIDs are a rare cause of SJS in adults; the risk is higher for older patients, women, and those initiating treatment. This includes upper respiratory infectionsotitis mediapharyngitisand Epstein-Barr virusMycoplasma pneumoniae and cytomegalovirus infections.

The routine use of syndrome such as antibioticsantipyretics and analgesics to manage infections can make it difficult to identify if cases were caused by link bactrim rash images stevens johnson syndrome johnson infection or medicines taken. Viral diseases reported to syndrome SJS include: Recent upper respiratory tract infections have been reported by more than half of patients with SJS.

Bacterial infections linked to SJS include group A beta-hemolytic streptococci, diphtheriabrucellosislymphogranuloma venereummycobacteriaMycoplasma pneumoniaerickettsial infectionstularemiaand typhoid.

Syndrome infections with coccidioidomycosisdermatophytosis, and histoplasmosis are also considered possible causes. SJS is a type IV hypersensitivity reaction in which bactrim rash images stevens johnson syndrome drug or its metabolite stimulates cytotoxic T cells i.

In particular, it is a type IV, subtype IVc, delayed hypersensitivity reaction dependent in images stevens johnson on johnson syndrome tissue-injuring actions of natural killer cells.

The DRESS syndrome bactrim rash is a Type IV, Subtype IVb, hypersensitivity drug reaction naltrexone starting dose implant in part on the tissue-injuring actions bactrim rash images stevens johnson syndrome eosinophils [29] [30] and acute generalized exanthematous pustulosis which is a Type IVsubtype IVd, hypersensitivity reaction dependent in part on the tissue-injuring actions of neutrophils.

Studies indicate bactrim rash images stevens johnson syndrome the mechanism by which a drug or its metabolites accomplishes this involves subverting the antigen presentation pathways of the innate immune system. The drug or metabolite covalently binds with a host protein to form a non-self, drug-related epitope.

Stevens-Johnson syndrome

An antigen presenting cell APC takes up these alter proteins; digests bactrim rash images stevens johnson syndrome into small peptides; places the peptides in a groove on the human leukocyte antigen i.

HLA component of syndrome major histocompatibility complex i. Alternatively, a drug or its metabolite may stimulate these Johnson syndrome cells by inserting into the groove on a Johnson syndrome protein to serve as a non-self epitope or bind outside of this groove to alter a HLA protein so that it forms a non-self epitope.

In all these cases, however, a non-self epitope bactrim rash images stevens johnson syndrome bind to a specific HLA serotype i. Since the human population expresses some 13, different HLA serotypes while an individual expresses only a fraction of them and since a SJS-inducing drug or metabolite interacts with only one or a few HLA serotypes, a drug's ability to induce SCARs is limited to those individuals who express Go here serotypes targeted by the drug or its metabolite.
