Design outcomes

Primary

MeasureTime frame
Main Objective: The aim of this study is to see whether the addition of Clindamycin, a protein inhibiting antibiotic, to the standard antibiotic treatment of limb cellulitis, with Flucloxacillin, results in less tissue damage and a more rapid resolution of both systemic and local features, in a cost-effective manner.;Secondary Objective: 1. Compare with placebo the effect of adjunctive clindamycin on the resolution of systemic features of sepsis (e.g. fever, tachycardia, neutrophil count and urea) at five and ten days post first dose of clindamycin 2. Evaluate clindamycin’s effect on limb swelling (by the measurement of limb circumference) and tissue damage (by the proportion of the limb affected) 3. Perform an economic evaluation to determine the cost-effectiveness of adjunctive clindamycin at 30 days. 4. Evaluate clindamycin’s effect on haematological parameters (e.g. white cell count, renal function and albumin) and how these relate to systemic and local features of cellulitis, to provide objective measures of severity 5. Document the duration between initial systemic features and the development of local signs (e.g.. swelling, pain, blistering and rash) 6. Examine the effect of the duration between systemic and local features and first dose of flucloxacillin on the subsequent duration and severity of celluliti;Primary end point(s): Primary outcome: Improvement at day 5 (range 4-6) based on a composite of systemic and local features: Temperature less than 37.5C, Reduction in limb swelling Reduction in local skin temperature ;Timepoint(s) of evaluation of this end point: Day 5

Secondary

MeasureTime frame
Secondary end point(s): Decrease in pain using a visual analogue score (VAS) at 30 days, Quality of life, measured by the Euroqol questionnaire at 30 days, that would allow to derive short-term Quality Adjusted Life Years Resolution of systemic features, resolution of composite inflammatory markers, Recovery of renal function, Return to work or normal activities, Absence of increased side-effects. ;Timepoint(s) of evaluation of this end point: VAS, Euroquol and return to normal activities at 30 days Systemic features, renal function and side effects at Day 5 and Day 10
