A reappraisal of ICU and long-term outcome of allogeneic hematopoietic stem cell transplantation patients and reassessment of prognosis factors: results of a 5-year cohort study (2009-2013).

Epidemiology and prognosis of complications related to allogeneic hematopoietic stem cell transplant (HSCT) recipients requiring admission to intensive care unit (ICU) have not been reassessed precisely in the past few years. We performed a retrospective single-center study on 318 consecutive HSCT patients (2009-2013), analyzing outcome and factors prognostic of ICU admission. Among these patients, 73 were admitted to the ICU. In all, 32 patients (40.3%) died in ICU, 46 at hospital discharge (63%) and 61 (83.6%) 1 year later. Survivors had a significantly lower sequential organ failure assessment (SOFA) score, serum lactate and bilirubin upon ICU admission. Catecholamine support, mechanical ventilation (MV) and/or renal replacement therapy during ICU stay, a delayed organ support and an active graft versus host disease (GvHD) significantly worsen the outcome. By multivariate analysis, the worsening of SOFA score from days 1 to 3, the need for MV and the occurrence of an active GvHD were predictive of mortality. In conclusion, the incidence of HSCT-related complications requiring an admission to an ICU was at 22%, with an ICU mortality rate of 44%, and 84% 1 year later. A degradation of SOFA score at day 3 of ICU, need of MV and occurrence of an active GvHD are main predictive factors of mortality.

Sirolimus-associated acute respiratory distress syndrome in a renal transplant recipient.

Sirolimus is a new potent immunosuppressive drug used in organ transplantation; its major advantage is the absence of deterioration in renal function. Documented adverse effects include myelosuppression and hyperlipidemia. Recently several cases of sirolimus-associated interstitial pneumonitis have been reported, usually of mild severity. We report a new case that was complicated by a severe acute respiratory distress syndrome, which required several days of mechanical ventilation. No infectious or cardiogenic etiology was documented. Low sirolimus blood levels and acute CD4 lymphocytic alveolitis suggested an immune-related mechanism rather than a direct toxic effect of the drug. The patient recovered after discontinuation of sirolimus and the administration of corticosteroids.

[Severe imported malaria in adults: a retrospective study of 32 cases admitted to intensive care units]. / Paludisme grave d'importation chez l'adulte: étude rétrospective de 32 cas admis en réanimation.

INTRODUCTION: Few studies have focused on severe imported malaria in patients admitted to intensive care units. We, therefore, undertook a retrospective study in the University Hospital of Montpellier. MATERIAL AND METHODS: All patients, more than 15 years-old with falciparum malaria who were admitted to intensive care units between October 1997 and April 2004 were included. Main epidemiological features, criteria of admission, treatment and outcome were investigated. RESULTS: Thirty-two patients were included, representing 9% of falciparum malaria cases diagnosed in the same period. The mean age was 44 years. All patients acquired falciparum malaria in sub-Sahara Africa and 25 patients were nonimmune. Chemoprophylaxis was absent or inadequate in 94%. The mean time from symptom onset and treatment initiation was 6 days. Mean parasitemia on admission was 15%. Criteria of admission were impaired consciousness in 69%, acute renal failure in 19% and isolated high parasitemia in 19% of the cases. All, but one received quinine therapy and a loading dose was performed in 34%. Seven patients (22%) had community-acquired coinfections and six (19%) had nosocomial infections. Mortality was 16%. Causes of death were refractory shock, cerebral edema, and acute respiratory distress syndrome. CONCLUSION: Severe imported malaria remains associated with a bad outcome. Improving chemoprophylaxis and an earlier diagnosis may reduce significantly this mortality.

[Epidemiology and prognosis of hyperosmolar state in the elderly]. / Epidémiologie et facteurs pronostiques des états hyperosmolaires chez le sujet âgé.

OBJECTIVE: We studied elderly patients admitted for hyperosmolar state (HS) to evaluate current outcome of HS and identify prognosis factors associated with mortality. STUDY DESIGN: A clinical retrospective study in an eight bed ICU. PATIENTS AND METHODS: Eighteen over 65-year-old patients admitted with a serum osmolality greater than 325 mOsm/kg were reviewed. Age, sex, diabetes mellitus, underlying medical condition, presence of an acute precipitating factor, Apache II and Glasgow scores, systolic arterial pressure, state of hydration, core temperature, heart rate, serum osmolality, creatininemia, lactatemia, plasma urea and bicarbonate, and protidemia were collected at the admission. Amount of fluid, time course of osmolality correction, length of hospitalization and mortality were recorded. All data were analyzed to identify possible correlations with patient outcome. RESULTS: Mean age: 75 +/- 11 years; sex ratio 1/2; hyperosmolar hyperglycemic states: 13 patients; hyperosmolar hypernatremic states: five patients; mean Apache II score: 18 +/- 7; Glasgow coma score: 11 +/- 3; mean osmolality: 370 +/- 25 mOsm/kg. In nine patients, infection was the precipitating factor. Five patients died (28%). At the admission, low blood pressure and high heart rate were related to mortality. During hospitalization, the occurrence of an acute cardiocirculatory failure and/or the need of mechanical ventilation significantly worsens the outcome. CONCLUSION: Our results showed that ICU mortality of HS in the elderly was at 28%. Haemodynamic state was the only factor of prognosis at the admission. Deaths were mostly related to acute respiratory and circulatory failure.

[Acute motor axonal neuropathy and aseptic meningitis due to Staphylococcus aureus endocarditis]. / Neuropathie axonale motrice aiguë et méningite aseptique révélant une endocardite à Staphylococcus aureus.

INTRODUCTION: Central nervous system complications are commonly described in Staphylococcus aureus endocarditis but peripheral nervous system involvement is rare. EXEGESIS: We report the case of a 65-year-old woman who had tetraparesia and aseptic meningitis revealing S. aureus endocarditis. The presence of purpura on the lower limbs led to an initial diagnosis of meningococcal meningitis. Tetraparesia was due to an acute motor axonal neuropathy. Anti-GM1 antibodies were negative. Meningitis and tetraparesia improved with antibiotic therapy. CONCLUSION: Acute motor axonal neuropathy may be a presenting symptom of S. aureus endocarditis.
