A Case of Rash with Fever
LM Parsons Division of Dermatology Feb 2014 Provide an approach to a patient presenting with rash and fever Underscore the importance of the history in making this diagnosis Discuss the meaning of a photo-distributed eruption This is a 16 year old student with a long history of RA just moved to Calgary from BC Arthritis has been flaring and she has missed most of the school year Moved closer to Calgary for closer access to her rheumatologist No skin problems until 2 weeks prior when she developed a fever (40 degrees) and began c/o a sore throat and then swollen glands under her neck and in her axilla and groin Seen in ER on day 2 and prescribed amoxicillin which she took for 3 days The following day, she began to develop an itchy rash, which was 3 days after the fever began Rash began with swelling around eyes and then noted on central chest, spreading up to face, proximal and then distal arms. Involvement of torso followed then legs, all over a 3 day period over a 3 day period. Rash evolved from pruritic to painful over 7 days Defervesce occurred on day 10 Rash described by K and family as itchy then painful Fingers swollen but hard to tell if this was her arthritis or the rash No suspected aggravating or relieving factors PMHX RA type arthritis Diagnosed Strep Pharyngitis in ER Meds ▪ Sulfsalazine begun 3 months before with a dose adjustment 2 weeks prior ▪ Plaquenil Dose unchanged for 15 months ▪ Amoxicillin – DC’d on day 5 of the fever Family History – non contributory No significant travel history Cutaneous ▪ morbilliform rash ▪ periorbital swelling but not photo-distributed ▪ no conjunctival involvement ▪ Palms and soles clear ▪ No nail fold changes MSK ▪ Painful swelling of joints of both hands and some of her toes ▪ Pain on movement of her left hip which restricts ROM Lymphoreticular ▪ Palpable lymphadenopathy in right submandibular and left groin. ( causing the left hip pain) ▪ Hepatomegaly determined to be present and was tender on palpation Why is the absence of a photo-distribution important in this case of rash and fever? A. B. C. A rash which exacerbates in areas of old sun damage A rash which appears on the skin only when the patients goes outside A rash which is found on skin in areas which are not photo-protected A. B. C.

No - urticaria are evanescent lesions seldom lasting more than 24 hours No - urticaria have as a primary lesion, small discrete papules Yes - urticaria are always associated with eosinophilia Yes - urticaria have eye involvement as a possible sequelae A.

Toxic erythema Toxic epidermal necrolysis Steven Johnson’s syndrome DRESS AGEP Amoxicillin rash in a case of Infectious Mononucleosis A. B. C. Amoxicillin Sulfasalazine Plaquenil A. B. C. Amoxicillin Sulfasalazine Plaquenil 70% of patients will have elevated transaminases and hepatomegaly This may persist for months The hepatitis is often anicteric and without cholangitis. 11% of DRESS patients will exhibit renal disease Allopurinol is the most common drug followed by carbamazepine and dapsone Pulmonary Minocycline is the most common drug causing lung pathology Cardiac Myocarditis- potentially fatal and can present months after withdrawal of the offending drug and resolution of the clinical and laboratory abnormalities Ampicillin and minocycline are the most commonly implicated drugs Provide an approach to a patient presenting with rash and fever Underscore the importance of the history in making this diagnosis Discuss the meaning of a photo-distributed eruption A. B. C. D. Yes – There are target lesions and mucosal involvement in this patient Yes - Ocular edema without conjunctival involvement is a prominent feature of SJS Yes- Fever is a prominent feature of SJS No – the clinical picture is not that of SJS A.

Yes – There are target lesions and mucosal involvement in this patient Yes - Ocular edema without conjunctival involvement is a prominent feature of SJS Yes- Fever is a prominent feature of SJS No – the clinical picture is not that of SJS A. B. C. D. Sulfa drugs Ampicillin Allopurinol Carbamazepine A. B. C. D. Sulfa drugs Ampicillin Allopurinol Carbamazepine immediate cessation of the causative medication(s). In cases in which the culprit drug is not obvious, clinicians must use their clinical judgment to select which medication to discontinue. They may also utilize patch or lymphocyte transformation tests to aid in identification when appropriate. Topical corticosteroids can be used for symptomatic relief, but systemic steroid therapy is generally required. Other immunosuppressants have also been employed in treatment and show promise in future therapy. Patients with DRESS syndrome should be managed in an intensive care or burn unit for appropriate care and infection control. In addition, appropriate specialists should be consulted based on the affected organ systems. Most patients recover completely after drug withdrawal and appropriate therapy. However, some patients with DRESS syndrome suffer from chronic complications and approximately 10% die, primarily from visceral organ compromise. Controlled clinical trials investigating the most appropriate therapies and their risks, particularly intravenous corticosteroids, are lacking, and would be invaluable in determining the optimal
