[Antifungal treatment for suspected or proved candidiasis in the critically ill]. / Traitements antifongiques en réanimation au cours des infections fongiques invasives documentées ou suspectées.

OBJECTIVE: Describe systemic antifungal therapy in non-neutropenic adult patients in intensive care unit (ICU). PATIENTS AND METHOD: A prospective, observational study was conducted during the first half of 2010 in the 7 ICU in a hospital with medical consultant on antimicrobial therapy. All non-neutropenic consecutive adult patients receiving systemic antifungal therapy for documented or suspected invasive fungal infection (IFI) apart from aspergillosis were included. RESULTS: Out of 1502 patients admitted in ICU, 104 (7 %) underwent systemic antifungal therapy, including 30 (29 %) for a documented IFI and 74 (71 %) for a suspected IFI. Candida albicans was identified in 23 (77 %) of the IFI and 45/52 (86 %) of the broncho-pulmonary and/or urinary colonizations in suspected IFI. Echinocandin was significantly more prescribed in patients with a documented infection (19/30 patients) and fluconazole in patients with a suspected infection (48/74 patients). The first line therapy was primarily stopped after recovery (11/30 patients) or de-escalation (9/30 patients) in documented infections, and for lack of indication (34/74 patients) or due to recovery (21/74 patients) in suspected infections after on average of 7 days of treatment. CONCLUSION: For ICU non-neutropenic adult patients in our center, antifungal therapy is prescribed two times out of three for suspected, unproved infections, in most cases with fluconazole. Documented infections were more often treated by echinocandin with secondary de-escalation. An interventional prospective study to assess the role of antifungal pre-emptive or empirical therapy is necessary.

[Antifungal treatments of candidemia in non-neutropenic patients: evaluation of practice in intensive care units]. / Traitements antifongiques des candidémies chez les patients non neutropéniques : évaluation des pratiques en réanimation.

OBJECTIVE: The authors had for objective to assess systemic antifungal treatment for candidemia in non-neutropenic patients, in intensive care units (ICU), and compare the results with French 2004 recommendations. STUDY DESIGN: A retrospective multicenter study (nine ICU in two teaching hospitals) was made. PATIENTS AND METHOD: Thirty-eight non-neutropenic patients with at least one positive blood culture for Candida who had received systemic antifungal treatment were included between May 2004 and September 2007. RESULTS: Thirty-nine cases of candidemia were analyzed. The median age was 54.5 (21-80), the median SAPS II score at admission was 44 (20-79), the median duration of stay in ICU was 22.5 days (2-82), and the death rate was 45%. Candida albicans was identified in 69% of the cases. Eight percent of Candida sp. isolates were resistant or susceptible dose-dependent (S-DD) to fluconazole. Before identification, fluconazole, caspofungin, voriconazole, and amphotericin B were used in 74%, 15%, 5%, and 5% of cases respectively. After identification and antifungal susceptibility determination, fluconazole was used in 68% of cases, caspofungin in 24% of cases, any formulation of amphotericin B in 6% of cases, voriconazole in 3% of cases. The French recommendations were applied in 71% of cases before identification and in 68% of cases after identification and antifungal susceptibility determination. CONCLUSION: The main causes of non-compliance to recommendations were the use of fluconazole in patients previously exposed to azole agents, the use of caspofungin in hemodynamically unstable patients, and the absence of therapeutic desescalade.

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.

[Thyreotoxic periodic paralysis. A cause of pseudo-paralysing hypokalemia that should not be ignored in Caucasians]. / Paralysie périodique thyréotoxique. Une cause d'hypokaliémie pseudoparalysante à ne pas méconnaître chez le Caucasien.

INTRODUCTION: Despite its rare occurrence in Caucasians, thyreotoxic periodic paralysis should be evoked in young male Caucasians presenting with episodes of pseudo-paralytic hypokalemia. OBSERVATION: A 37 year-old Caucasian was admitted in intensive care for an acute episode of hypotonic tetraplegia and hypokalemia during which laboratory tests revealed hyperthyroidism due to Basedow's disease. The clinical course was rapidly favourable after a small dose of intravenous potassium. Antithyroid treatment avoided any new occurrence of similar episodes. DISCUSSION: In Caucasians, sporadic acute paralysis with hypokalemia requires testing for hyperthyroidism. Though it is well know that hypokalemia results from potassium intracellular shift, the underlying mechanism remains poorly elucidated. Treatment includes potassium administration with caution and/or beta blockers but the specific treatment is that of hyperthyroidism.

[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.

[Clinical and epidemiologic characteristics of acute diarrhea in adults at a hospital from Cordoba city]. / Caracteristicas clinico-epidemiologicas de la diarrea aguda del adulto en un hospital de la ciudad de Cordoba.

The purpose of this work was to assess the clinical and epidemiologic presentation features of adult acute diarrhea in a general hospital form Córdoba City. All the patients older than 14 years old who assisted to the Hospital Nacional de Clínicas Central Guard for acute diarrhea, during the periods: A (15-12-89 to 15-03-90), B (15-12-93 to 15-03-94) and C (15-12-94 to 15-03-95), were included. 594 patients were studied: 337 female (56.7%) and 257 male, 143 in the period A, 250 in B and 201 in C. The means +/- SD age was 34.6 +/- 13.3 and stool loose per day at admission 7.3 +/- 4.7. Eighty six percent of patients presented liquid consistent stool, 89.6% abdominal pain, 44.7% vomiting and 18.8% bloody stools. The rate of patients who consulted Central Guard referring acute diarrhea increased from period A (2.4%) to B (3.61%); p = 0.002 and decreased form B to C (2.85%); p = 0.01. The mean (+/- SD) days transcurred from the beginning of diarrhea episode till consultation was 3.5 +/- 2.7; 2.7 +/- 2.3 y 2.9 +/- 3.5 in the periods A, B and C respectively, statistically significant difference between A and B, p < 0.01. Thirty six percent, 21.1% and 23.1% of patients presented mucus with their stools in the periods A, B and C (p = 0.01), and high temperature 61.1%, 48.1% and 48.5% respectively (p = 0.04). Twenty seven percent of stools samples cultures became positive in the periods A, 17.6% in B and 11.5% in C, statistically significant difference between A and C; p = 0.008. The results show that in a general hospital from Córdoba City the adult acute diarrhea is a frequent cause of consult. In the last years there were modifications in its clinical an epidemiologic presentation features.
