Brief summary

Cellulitis is the medical term for an infection of the skin, with symptoms including redness, swelling, warmth, and pain. This group of symptoms is called inflammation, and is caused by the body's immune system responding to the infection. Standard care for cellulitis is using antibiotics to destroy the infection, but the inflammation can persist and cause a great deal of pain. The hypothesis of this study is that adding a single dose of an oral steroid (prednisone), which tempers the immune response, will reduce inflammation, reduce pain, and speed recovery. This hypothesis will be examined by recruiting a group of patients with cellulitis, and randomizing them to two sub-groups: one group will receive a dose of prednisone, while the other group will receive a placebo. Neither group will know what they received unless there is a problem. These subjects will be followed up at the 48 hour mark and the 7 day mark, and will have their results compared.

Detailed description

This pilot study will be conducted in a prospective, double-blinded, placebo-controlled, randomized fashion using a convenience sample of 100 subjects who come to the ED with signs and symptoms of cellulitis. Initial medical assessment will be made by an attending/senior resident according with established clinical procedures, including the history, physical examination, and vital signs. If by clinical assessment the patients meet eligibility criteria, then they will be approached by a research associate for screening, informed consent process, enrollment in the study, and data collection. After the subjects understand and sign the informed consent form, they will be randomized to either the placebo group or treatment group. The EMCP pharmacy will be in charge of the randomization process. Once randomized, a standard source document (see data management section and appendix C for details) will be filled with information given by the subjects and in their charts. While study medication is given (time zero), subjects will receive a Visual Analog Scale (VAS) to rate their pain upon initial presentation along with determination of size of the cellulitic area. This will be done by determining the longest axis of the cellulitic area and measuring it (in mm) from the most proximal/lateral end towards the most distal/medial end, excluding any lymphangitic spread. The most proximal and distal area of erythema will be outlined. While the standard treatment of care for cellulitis will be circumscribed according to already established protocols, the class of antibiotics and pain control that patients receive will depend on their disposition: If discharged: 1. Antibiotic prescriptions will be TMP/SMX 160/800 mg (Bactrim DS), 2 pills PO BID and Cephalexin 500 mg PO qid; if allergic, Clindamycin 300 mg PO QID. 2. Pain control: during stay in the ED subjects will receive, according to their allergic history and as long as the treating physician determines it is necessary to address the pain, two tablets of either Percocet 5/325 mg,Vicodin 5/500 mg (if allergic to Percocet), or Acetaminophen 500 mg as an only dose. Once discharged they will receive, according to their allergic history and the physician's clinical judgement, a prescription of 12 tablets of either Percocet 5/325 mg, Vicodin 5/500 mg (if allergic to Percocet), Tylenol #3 300/30 mg, or Acetaminophen 500 mg, one tablet PO q6 and PRN for pain. Pain medication must not include NSAIDs. If admitted to observation unit: antibiotics will be IV Clindamycin 300 mg q6 hours; if allergic, IV Vancomycin 1 g q12 hours should be given. For pain control: Morphine 4 mg IV q4 hours and PRN pain; if allergic, Dilaudid 1 mg IV q4 hours and PRN if pain. Pain medication must not include NSAIDs. Once discharged, they will receive the same prescription as the discharged group of subjects. In addition to the standard of care described and any additional medications deemed appropriate by the attending physician that do not represent a confounding factor to the study (NSAIDs, other antibiotics), subjects will also receive an additional pill which will be either prednisone 60 mg or placebo. If the treating physician feels it is in the best interest of the subject to break the protocol, the subject's participation in study procedures will end. Data that has already been collected will be kept, and may be analyzed separately. Once the subjects have received the study medications, they will follow their dispositions (either be discharged or be admitted in the observation's unit). To assure treatment compliance, the Research Associate will provide the subjects with antibiotics and pain medication treatment corresponding to the first 48 hours. After this landmark, the subjects will cover the rest of their treatment. Subjects will be instructed not to take any medication outside the prescription during the length of the study. If the subjects take NSAIDs during the first 48 hours, this could be considered a confounding factor. As such, subjects who take NSAIDs within the first 48 hours will have their participation in study procedures ended. Their already collected data will be kept and may be analyzed separately; however, if they take NSAIDs after the 48-hour visit their study participation will continue. Subjects will be required to return to the ED after 48 hours and bring the remaining prescribed pain medications. They will meet a Research Associate for re-evaluation, which will be done by using a VAS, measuring the cellulitic area, and assessing the degree of usage of the prescribed pain medications. This second visit is not part of the standard of care so patients won't be required to receive a formal evaluation by an ED doctor nor register in triage. Financial compensation will be provided on completion of the 48 hour follow-up visit for all patients. A seventh (± one) day follow-up call will be done to assess pain severity, degree of symptomatic recovery and disappearance of the erythema, and need of additional medical assistance.
