Community acquired fungemia caused by Candida pulcherrima: diagnostic contribution of MALDI-TOF mass spectrometry

BACKGROUND: Community-onset candidemia constitute a distinct clinical entity the incidence of which is increasing. Contribution of non-albicans Candida species is rising. CASE PRESENTATION: We describe here the first reported case of community acquired fungemia due to Candida pulcherrima. Identification to the species level was performed by MALDI-TOF mass spectrometry. Treatment with fluconazole was successful. CONCLUSION: This case confirms the pathogenic role of C. pulcherrima and the contribution of MALDI-TOF mass spectrometry for identification of rare Candida species

Neurological manifestations of COVID-19 in adults and children

Different neurological manifestations of coronavirus disease 2019 (COVID-19) in adults and children and their impact have not been well characterized. We aimed to determine the prevalence of neurological manifestations and in-hospital complications among hospitalized COVID-19 patients and ascertain differences between adults and children. We conducted a prospective multicentre observational study using the International Severe Acute Respiratory and emerging Infection Consortium (ISARIC) cohort across 1507 sites worldwide from 30 January 2020 to 25 May 2021. Analyses of neurological manifestations and neurological complications considered unadjusted prevalence estimates for predefined patient subgroups, and adjusted estimates as a function of patient age and time of hospitalization using generalized linear models. Overall, 161 239 patients (158 267 adults; 2972 children) hospitalized with COVID-19 and assessed for neurological manifestations and complications were included. In adults and children, the most frequent neurological manifestations at admission were fatigue (adults: 37.4%; children: 20.4%), altered consciousness (20.9%; 6.8%), myalgia (16.9%; 7.6%), dysgeusia (7.4%; 1.9%), anosmia (6.0%; 2.2%) and seizure (1.1%; 5.2%). In adults, the most frequent in-hospital neurological complications were stroke (1.5%), seizure (1%) and CNS infection (0.2%). Each occurred more frequently in intensive care unit (ICU) than in non-ICU patients. In children, seizure was the only neurological complication to occur more frequently in ICU versus non-ICU (7.1% versus 2.3%, P < 0.001). Stroke prevalence increased with increasing age, while CNS infection and seizure steadily decreased with age. There was a dramatic decrease in stroke over time during the pandemic. Hypertension, chronic neurological disease and the use of extracorporeal membrane oxygenation were associated with increased risk of stroke. Altered consciousness was associated with CNS infection, seizure and stroke. All in-hospital neurological complications were associated with increased odds of death. The likelihood of death rose with increasing age, especially after 25 years of age. In conclusion, adults and children have different neurological manifestations and in-hospital complications associated with COVID-19. Stroke risk increased with increasing age, while CNS infection and seizure risk decreased with age

Mycobacterium mucogenicum bacteremia: major role of clinical microbiologists

Abstract Introduction Mycobacterium mucogenicum is a rare but emerging cause of infections, especially in immunocompromised patients. Case presentation We describe a new case of M. mucogenicum catheter-related bloodstream infection in a 34-year-old woman with ovarian cancer. M. mucogenicum was at first considered as a contaminant, and susceptibility testing was not performed. Usual susceptibility of M. mucogenicum motivated prescription of clarithromycin and moxifloxacin. Finally, our isolate was confirmed susceptible to both drugs. Clinical outcome was favorable with no relapse of infection after antibiotics discontinuation despite concomitant chemotherapy. Conclusion Our case illustrates the need for a clinician-microbiologist dialogue in case of suspected M. mucogenicum infection to avoid delaying appropriate management

Spondylitis Due to Mycobacterium xenopi in a Human Immunodeficiency Virus Type 1-Infected Patient: Case Report and Review of the Literature

Nontuberculous mycobacterial infections are well known to occur in patients with human immunodeficiency virus infection. However, spondylitis due to mycobacteria other than Mycobacterium tuberculosis is uncommon. We report a case of biopsy- and culture-proven Mycobacterium xenopi spondylitis in an AIDS patient and discuss approaches to diagnosis and therapy. This case serves to highlight the potential pathogenic role of this usually environmental commensal organism in severely immunosuppressed AIDS patients and uncertainties in their management, given the scarce data on appropriate therapy for this organism
