Factores predictivos de mortalidad en la gangrena de Fournier: serie de 59 casos / Predictive factors for mortality in Fournier’ gangrene: A serie of 59 cases

OBJETIVOS: La gangrena de Fournier (GF) es la fascitis necrosante del periné y área genital que presenta una elevada mortalidad. El objetivo es analizar los factores pronósticos de mortalidad, creación de una nueva escala predictiva de mortalidad y compararla con las ya validadas en los pacientes diagnosticados de GF en nuestro Servicio de Urgencias. MÉTODOS: Estudio analítico, retrospectivo entre 1998 y 2012. RESULTADOS: De los 59 casos, 44 sobrevivieron (74%) (S) y 15 fallecieron (26%) (E). Se encontraron diferencias significativas en la vasculopatía periférica (S 5 [11%]; E 6 [40%]; p = 0,023), hemoglobina (S 13; E 11; p = 0,014), hematocrito (S 37; E 31,4; p = 0,009), leucocitos (S 17.400; E 23.800; p = 0,023), urea (S 58; E 102; p < 0,001), creatinina (S 1,1; E 1,9; p = 0,032), potasio (S 3,7; E 4,4; p = 0,012) y fosfatasa alcalina (S 92; E 133; p = 0,014). Escalas predictivas: índice de Charlson (S 1; E 4; p = 0,013), criterios de sepsis grave (S 16 [36%]; E 13 [86%]; p = 0,001), Fournier's gangrene severity index score (FGSIS) (S 4; E 7; p = 0,002) y Uludag Fournier's Gangrene Severity Index (UFGSI) (S 9; E 13; p = 0,004). Los factores predictores independientes fueron la vasculopatía periférica, el potasio sérico y criterios de sepsis grave, creando un modelo con área bajo la curva de 0,850 (0,760-0,973) superior al FGSIS (0,746 [0,601-0,981]) y al UFGSI (0,760 [0,617-0,904]). CONCLUSIONES: La GF presentó una tasa de mortalidad elevada cuyos factores predictores independientes fueron la vasculopatía periférica, el potasio sérico y criterios de sepsis grave, creando un modelo con una capacidad discriminativa superior al resto

AIMS: Fournier's gangrene (FG) is the necrotizing fasciitis of the perineum and genital area and presents a high mortality rate. The aim was to assess prognostic factors for mortality, create a new mortality predictive scale and compare it with previously published scales in patients diagnosed with FG in our Emergency Department. METHODS: Retrospective analysis study between 1998 and 2012. RESULTS: Of the 59 patients, 44 survived (74%) (S) and 15 died (26%) (D). Significant differences were found in peripheral vasculopathy (S 5 [11%]; D 6 [40%]; P = .023), hemoglobin (S 13; D 11; P = .014), hematocrit (S 37; D 31.4; P = .009), white blood cells (S 17,400; D 23,800; P = .023), serum urea (S 58; D 102; P < .001), creatinine (S 1.1; D 1.9; P = .032), potassium (S 3.7; D 4.4; P = .012) and alkaline phosphatase (S 92; D 133; P = .014). Predictive scores: Charlson index (S 1; D 4; P = .013), severe sepsis criteria (S 16 [36%]; D 13 [86%]; P = .001), Fournier's gangrene severity index score (FGSIS) (S 4; D 7; P = .002) and Uludag Fournier's Gangrene Severity Index (UFGSI) (S 9; D 13; P = .004). Independent predictive factors were peripheral vasculopathy, serum potassium and severe sepsis criteria, and a model was created with an area under the ROC curve of 0.850 (0.760-0.973), higher than FGSIS (0.746 [0.601-0.981]) and UFGSI (0.760 [0.617-0.904]). CONCLUSIONS: FG showed a high mortality rate. Independent predictive factors were peripheral vasculopathy, potassium and severe sepsis criteria creating a predictive model that performed better than those previously described
