[Caspofungin after solid organ transplantation in Germany: observational study on treatment of invasive fungal infections]

[Severe Candida sepsis in a 28-year-old female patient with initial diagnosis of diabetes mellitus and marked hyperosmolar coma]

We report on a 28-year-old female patient who had no history of diseases and who was brought to our intensive care unit in a comatose state by the ambulance service. The clinical picture corresponded to sepsis with a massively increased blood sugar concentration (> 2000 mg/dl) as well as a pronounced skin mycosis in the groin region of the very obese patient (body mass index [BMI]: 33.7 kg/m²) in the physical examination. The treatment of sepsis was initially supplemented by a calculated antifungal treatment. The blood culture diagnosis confirmed the presence of Candida albicans and Candida glabrata. Despite adequate anti-infective treatment, the patient developed a septic shock in the further course, so that the additional escalation of treatment was initiated by renal replacement therapy on the second day and venovenous extracorporeal membrane oxygenation because of an ARDS. Despite all of these measures and maximum intensive care treatment, the patient developed a progressive multiple organ failure. When the pupils became rigid to light, a cerebral computed tomography was carried out. This showed evidence of a severe cerebral edema without signs of cerebral bleeding. Multiple examinations of somatosensory evoked potentials and electroencephalograms showed signs of irreversible brain damage. In view of this poor prognosis the therapeutic measures were limited. The patient died on day 24 after admission to the intensive care unit. The case study shows that antifungal treatment should definitely be considered in the context of sepsis treatment if there is a clinically justified suspicion.The role of the severely altered metabolic situation with massive hyperglycemia and ketoacidosis cannot be finally assessed.

Salvage combination antifungal therapy for acute invasive aspergillosis may improve outcomes: a systematic review and meta-analysis

OBJECTIVE

A meta-analysis was performed to compare mold-active triazoles or lipid amphotericin B plus an echinocandin to non-echinocandin monotherapy for acute invasive aspergillosis (IA).

METHODS

We searched PubMed, EMBASE, and other databases through May 2013 unrestricted by language. We included observational and experimental studies wherein patients with proven or probable IA by EORTC/MSG criteria underwent our comparative intervention. PRISMA and MOOSE guidelines were followed and quality was assessed using the Jadad and Newcastle-Ottawa criteria. Meta-regression with fixed and random effects and sensitivity analyses were performed. The primary study outcome measure was 12-week overall mortality. The secondary outcome assessed was complete and partial response.

RESULTS

Only observational studies of primary 12-week survival showed heterogeneity (I(2)=48.96%, p=0.05). For salvage IA therapy, fixed effects models demonstrated improved 12-week survival (Peto odds ratio (OR) 1.80, 95% confidence interval (CI) 1.08-3.01) and success (Peto OR 2.17, 95% CI 1.21-3.91) of combination therapy. Significance remained after applying random effects as a sensitivity analysis (12-week survival: Peto OR 1.90, 95% CI 1.04-3.46, and unchanged value for success). Restriction to high quality studies and including echinocandins as the comparator for refractory IA revealed an adjusted OR of 1.72 (95% CI 0.96-3.09; p=0.07) for global success, while the survival endpoint remained unaltered.

CONCLUSIONS

Combination antifungals for IA demonstrate improved outcomes over monotherapy in the salvage setting. Clinicians should consider this approach in certain situations.
