RESUMO
The European Society of Clinical Microbiology and Infectious Disease (ESCMID) has advised against the use of metronidazole for fulminant Clostridioides difficile (C. difficile) infection (CDI) in their latest guidelines. They suggest using oral vancomycin alone instead. This recommendation is based on a few retrospective studies, which have multiple biases. We evaluated the three studies that led ESCMID to advise against intravenous metronidazole for fulminant CDI and performed a meta-analysis. The meta-analysis revealed a mild (2.7%), not statistically significant (p=0.8) difference in mortality between the two groups. The high heterogeneity (I2= 89%) should also be noted. The decision to add or remove metronidazole should be discussed in the near future. In the meantime, combination therapy could be a cautious treatment for fulminant CDI.
RESUMO
BACKGROUND: Malaria during pregnancy is associated with a greater risk of complications for the mother and fetus. The aim of the study is to analyze the features of imported cases of malaria in pregnant women in Europe and evaluate which factors are associated with a non-favourable outcome. METHODS: A computerized search of the literature was performed combining the terms plasmod*, malaria, pregnan*, maternal, gravid, parturient, expectant, and congenital, from January 1997 to July 2023. RESULTS: 28 articles reporting 57 cases of malaria in pregnant women immigrant in non-endemic areas were included. The patients mainly came from Sub-Saharan Africa. There were 10 asymptomatic cases, while the predominant clinical syndrome among the symptomatic women was fever associated with anaemia. The median latency period from permanence in endemic areas and diagnosis in European countries was 180 days (IQR 15-730). Pregnancy outcomes were favourable in 35 cases (61 %): all term pregnancies, no low-birth-weight newborns. There were 4 abortions; 1 child was delivered pre-term; 7 babies were reported to have a low birth weight; 10 cases of congenital malaria were documented. P. falciparum was found with a higher frequency in women with a favourable outcome, while P. vivax was, in all cases, associated with a worse prognosis. CONCLUSIONS: Diagnosis of malaria in pregnant woman in non-endemic countries may be challenging and a delay in diagnosis may lead to an adverse outcome. Screening for malaria should be performed in pregnant women from endemic areas, especially if they present anaemia or fever.

Human Pseudomonas infections have high morbidity and mortality rates. Pseudomonas bacteria can cause sepsis or septic shock; they produce biofilm and commonly exhibit a multidrug-resistant phenotype. The choice of antimicrobial therapy in many cases is challenging, and deep knowledge of clinical, microbiological, and pharmacological issues is required. Intravenous fosfomycin is being repurposed in a combination given its favorable pharmacokinetic/pharmacodynamic properties (a small molecule with favorable kinetic both in bloodstream infection and in deep-seated infections), antibiofilm activity, and its interesting synergistic effects with other antimicrobials. Recent literature on epidemiological, microbiological, pharmacological, and clinical data on intravenous fosfomycin therapy against Pseudomonas is herein reviewed and discussed.
RESUMO
During the Coronavirus Disease 2019 (COVID-19) pandemic, an increasing number of fungal infections associated with SARS-CoV-2 infection have been reported. Among them, cryptococcosis could be a life-threatening disease. We performed a Systematic Review (PRISMA Statement) of cryptococcosis and COVID-19 co-infection, case report/series were included: a total of 34 cases were found, then we added our case report. We collected patients' data and performed a statistical analysis comparing two groups of patients sorted by outcome: "dead" and "alive". Three cases were excluded for lack of information. To compare categorical data, we used a Fisher-exact test (α=0.05). To compare quantitative variables a U Mann-Whitney test was used (α=0.05), with a 95% Confidence Interval. A total of 32 co-infected patients were included in the statistical analysis. Mortality rate was 17/32 (53.1%): these patients were included in "dead" group, and 15/32 (46.9%) patients survived and were included in "alive" group. Overall, males were 25/32 (78.1%), the median age was 60 years (IQR 53-70) with non-statistically significant difference between groups (p=0.149 and p=0.911, respectively). Three variables were associated with mortality: ARDS, ICU admission and inadequate treatment. Overall, 21 out of 24 (87.5%) patients were in ARDS with a statistically significant difference among two groups (p=0.028). ICU admission for COVID-19 was observed in 18/26 (69.2%), more frequently among dead group (p=0.034). Finally, 15/32 (46.9%) patients had adequate treatment (amphotericin B + flucytosine for invasive cryptococcosis) mostly among alive patients (p=0.039). In conclusion, mortality due to cryptococcal infection among COVID-19 patients remains high but an early diagnosis and appropriate treatment could reduce mortality.
RESUMO
Bacillus Calmette-Guérin (BCG), a live, attenuated strain of Mycobacterium bovis, is the essential constituent of the vaccine against tuberculosis and the gold-standard adjuvant treatment for urothelial cancer of the bladder. Being a live, attenuated strain with a potential pathogenic action, bacilli can cause several complications, both locally near the inoculation site and remotely through blood dissemination. BCG-related disease can represent a side effect of anti-TB vaccination in patient with congenital or acquired immunodeficiency or a complication of the therapeutic schedule in oncologic patients. Herein we report five cases of BCG-related disease which occurred at the Infectious Diseases Department of the University Hospital of Palermo during a five-year period from January 2014 to December 2019.
