RESUMO

BACKGROUND: Clostridium septicum bacteremia is often associated with occult malignancies (approximately 80%), especially of the right colon. Furthermore, inflammation of the aortic wall can rapidly lead to aneurysm induction through bacterial seeding into atheromatous lesions with consecutive life-threatening rupture. We summarize all published data on this rare and lethal disease to evaluate therapeutic approaches and give valid treatment recommendations because there are no guidelines. METHODS: A systematic review of the literature was conducted screening EMBASE and MEDLINE databases following the PRISMA guidelines with search period from first description to August 25, 2021. RESULTS: There were 72 cases of C septicum aortitis reported in 64 publications. Endovascular aortic repair (EVAR) was performed in a minority of patients (n = 6) unfit for surgery but lacked long-term survivors. Antibiotic treatment was beneficial in a bridge to surgery concept, but up to now harbored a 6-month mortality rate of 100% (median overall survival, 0.5 months) when no additional aortic repair was performed. Open aortic repair was the only potential curative approach but was accompanied with a 90-day-mortality of 26.7% (4/15). CONCLUSIONS: Open aortic repair combined with perioperative antibiotic treatment should be offered to all patients as the only potentially curative approach. If applicable, resection of a coexisting colonic tumor should be performed after successful aortic repair. Alternatively, long-term antibiotic treatment can be offered to patients unfit for surgery in a palliative setting. Endovascular aortic repair has been performed on a minority of patients with a high risk for stent graft infection and should remain a salvage strategy when therapeutic pressure demands acute intervention in patients unfit for surgery.

RESUMO

BACKGROUND: Diagnosis and treatment of diverticulitis in immunosuppressed patients are more challenging than in immunocompetent patients, as maintenance immunosuppressive therapies may mask symptoms or impair the patient's ability to counteract the local and systemic infective sequelae of diverticulitis. The purpose of this study was to compare the in-hospital mortality and morbidity due to diverticulitis in immunosuppressed and immunocompetent patients and identify risk factors for lethal outcomes. METHODS: This retrospective study included consecutive in-patients who received treatment for colonic diverticulitis at our institution between April 2008 and April 2014. Patients were divided into immunocompetent and immunosuppressed groups. Primary end points were mortality and morbidity during treatment. Risk factors for death were evaluated. RESULTS: Of the 227 patients included, 15 (6.6%) were on immunosuppressive therapy for solid organ transplantation, autoimmune disease, or cerebral metastasis. Thirteen of them experienced colonic perforation and showed higher morbidity (p = 0.039). Immunosuppressed patients showed longer stays in hospital (27.6 v. 14.5 d, p = 0.016) and in the intensive care unit (9.8 v. 1.1 d, p < 0.001), a higher rate of emergency operations (66% v. 29.2%, p = 0.004), and higher in-hospital mortality (20% v. 4.7%, p = 0.045). Age, perforated diverticulitis with diffuse peritonitis, emergency operation, C-reactive protein > 20 mg/dL, and immunosuppressive therapy were significant predictors of death. Age (hazard ratio [HR] 2.57, p = 0.008) and emergency operation (HR 3.03, p = 0.003) remained significant after multivariate analysis. CONCLUSION: Morbidity and mortality due to sigmoid diverticulitis is significantly higher in immunosuppressed patients. Early diagnosis and treatment considering elective sigmoid resection for patients with former episodes of diverticulitis who are wait-listed for transplant is crucial to prevent death.


BACKGROUND: Le diagnostic et le traitement des diverticulites sont plus délicats chez les patients immunosupprimés que chez les patients immunocompétents, étant donné que les thérapies immunosuppressives d'entretien peuvent masquer les symptômes ou réduire la capacité du patient à lutter contre les infections locales ou systémiques pouvant découler de la diverticulite. La présente étude avait pour but de comparer les taux de mortalité et de morbidité en milieu hospitalier associés à la diverticulite chez des patients immunosupprimés et immunocompétents et de cerner les facteurs de risque de décès. METHODS: Cette étude rétrospective portait sur des patients traités consécutivement pour une diverticulite du côlon hospitalisés dans notre établissement entre avril 2008 et avril 2014. Les patients ont été divisés en 2 groupes : immunocompétents et immunosupprimés. Les résultats primaires à l'étude étaient la mortalité et la morbidité pendant le traitement, et nous avons évalué les facteurs de risque de décès. RESULTS: Parmi les 227 patients retenus, 15 (6,6 %) suivaient une thérapie immunosuppressive en raison d'une greffe d'organe plein, d'une maladie auto-immune ou de métastases cérébrales. Parmi eux, 13 ont subi une perforation du côlon et présentaient un taux de morbidité supérieur (p = 0,039). Les patients immunosupprimés sont restés plus longtemps à l'hôpital (27,6 j c. 14,5 j, p = 0,016) et à l'unité de soins intensifs (9,8 j c. 1,1 j, p < 0,001), et présentaient des taux supérieurs d'intervention d'urgence (66 % c. 29,2 %, p = 0,004) et de mortalité pendant l'hospitalisation (20 % c. 4,7 %, p = 0,045). L'âge, une diverticulite perforée avec péritonite diffuse, une opération d'urgence, un résultat de protéine C réactive > 20 mg/dL et une thérapie immunosuppressive étaient des prédicteurs de décès significatifs. L'âge (rapport de risque [RR] 2,57, p = 0,008) et une opération d'urgence (RR 3,03, p = 0,003) sont demeurés significatifs après l'exécution d'une analyse multivariée. CONCLUSION: Les taux de morbidité et de mortalité attribuables à une diverticulite du sigmoïde sont significativement plus élevés chez les patients immunosupprimés que chez les autres patients. Afin de prévenir les décès, il est essentiel de diagnostiquer et de traiter rapidement, possiblement par résection du sigmoïde, les patients ayant déjà souffert de diverticulite qui sont sur une liste d'attente pour une greffe.
