Implementation of a multidisciplinary infectious diseases team in a tertiary hospital within an Antimicrobial Stewardship Program.

BACKGROUND: In January 2011, as part of an antimicrobial stewardship program the Antimicrobial Management Team (AMT) at the Ghent University Hospital initiated a multidisciplinary Infectious Diseases Team (MIT) consisting of infectious diseases physicians, clinical microbiologists, and clinical pharmacists. The aim of this study is to describe the type and acceptance rate of recommendations provided by the MIT. METHOD: Prospective, observational study in a tertiary care, university teaching hospital with 1062 beds in non-consecutive hospitalized adult patients, excluding intensive care units and paediatrics. RESULTS: The MIT communicated 432 recommendations in 87 days observed. Of the 293 patients for whom a recommendation was made, the median age was 57 years (range: 16-91 years) and 169 (57·7%) were male. Skin or soft tissue infections (14%), respiratory tract infections (13%), infections without known focus (11%), abdominal infections (11%), and bone infections (8%) were most common. Recommendations were made to perform additional clinical investigation(s) [N = 137 (27%)], to adjust the dose of an antimicrobial drug [N = 42 (8%)], to stop an antimicrobial drug [N = 104 (21%)], to switch from a parenteral to an oral drug [N = 39 (8%)] or to initiate an antimicrobial drug [N = 178 (36%)], with an acceptance rate of 73·0%, 83·3%, 81·7%, 76·9%, and 84·0%, respectively. CONCLUSIONS: The MIT formulated about five recommendations a day primarily focusing on pharmacotherapy, but also on clinical investigations. In both fields, a high acceptance rate was observed.

Calciphylaxis: a rare complication in alcoholic liver disease.

Calciphylaxis, or calcific uremic arteriolopathy (CUA) is a rare but well described entity in patients with endstage renal disease (ESRD) and/or hyperparathyroidism. CUA is characterized by systemic acute calcification of the small and intermediate dermal vasculature that can lead to epidermal ischemia, ulceration, and necrosis. Cutaneous lesions of calciphylaxis characteristically begin as tender, violaceous, livedoid discolorations. The mechanisms of disease remain poorly understood although abnormal bone and mineral metabolism and hyperparathyroidism can contribute to CUA. Therapeutic strategies are of unproven benefit and mortality remains high. Calciphylaxis has also been extremely rarely reported in patients without ESRD and/or hyperparathyroidism. We report an unusual case of calciphylaxis in a patient with alcoholic liver cirrhosis and normal renal function, without any alteration in the phosphocalcic and parathyroid hormone (PTH) metabolisms.

Invasive aspergillosis in patients with cirrhosis, a case report and review of the last 10 years.

BACKGROUND: Untreated invasive aspergillosis (IA) is lethal, yet diagnosis is often delayed. Recognising the risk factors can lead to earlier diagnosis. We present a case of an invasive pulmonary aspergillosis in a patient with cirrhosis, who had been treated with corticosteroids for 2.5 weeks for alcoholic hepatitis. He was successfully treated with liposomal amphotericin B and caspofungin (first in combination, then caspofungin monotherapy). PURPOSE: To evaluate the role of aspergillosis in cirrhosis. METHODS: A literature search on aspergillosis in cirrhosis and liver failure patients was conducted in PubMed/Medline (2002-dec 2012), according to pre-set selection criteria. RESULTS: 20 out of 330 articles were retrieved, representing 43 patients with cirrhosis and/or liver failure who had an aspergillosis infection. Most Aspergillus (A.) infections were due to A. fumigatus and the lungs were the most frequent organ involved (42/43). 58% of the patients used steroids and mortality was 53.5%. The most frequent used antifungal was caspofungin. DISCUSSION: Diagnosis of IA is difficult and there might be a delay in diagnosis since cirrhosis is not recognised as one of the classical risk factors. Mortality was 53.5%, but this is lower than in previous decades. Since voriconazole is hepatotoxic, treatment with caspofungin and/or amphotericin is preferable. CONCLUSION: Early recognition of aspergillosis in a cirrhosis/liver failure patient is crucial and should prompt direct treatment.

Cyclic vomiting syndrome: case report and short review of the literature.

Cyclic vomiting syndrome (CVS) is a functional disorder that is considered to be a manifestation of migraine diathesis. It is characterized by stereotypical episodes of severe nausea and vomiting lasting several hours or days, with return to baseline health between episodes. CVS is still an insufficiently known syndrome among physicians, and is therefore often misdiagnosed. Treatment focuses on the different phases of CVS, with interepisodic prophylaxis, abortive therapy in the prodromal phase of CVS, and supportive care during an acute vomiting episode. Anti-migraine medications have been effectively used for prophylaxis in many patients. We report a case of CVS successfully treated with flunarizine, a non-selective calcium antagonist.

Glucocorticoid hypertension due to the use of bleaching skin cream, a case report.

We report on an unusual case of a 28-year old African woman who developed glucocorticosteroid induced arterial hypertension after abusive use of a skin bleaching cream. Glucocorticosteroids exert their effect at many different sites involved in blood pressure regulation: in particular at the level of the kidney, blood vessels and the heart. The exact incidence of arterial hypertension after prolonged cutaneous glucocorticosteroid administration is unknown. The mechanism of glucocorticosteroid induced hypertension is discussed.
