Evaluation of the expanding spectrum of sertraline against uncommon fungal pathogens.

The emergence of non-Aspergillus mold pathogens has increased notoriously in the last decades with serious health consequences. The options of treatment for these microorganisms often resistant to a wide variety of antifungals is limited. Sertraline is an antidepressant with in vitro and in vivo antifungal properties which has been recently studied as an adjuvant in the treatment of invasive infections. In this study, we evaluated the in vitro interaction of sertraline with voriconazole and amphotericin B against Lomentospora prolificans, Scedosporium spp., Fusarium spp., Paecilomyces spp., Alternaria spp. and Curvularia spp. The minimum inhibitory concentration and minimum fungicidal concentration for sertraline were in the range of 8-32 µg/mL. Sertraline showed antifungal capacity against all fungi tested and synergism in combination with amphotericin B against some strains of Lomentospora prolificans, Scedosporium apiospermum and Alternaria alternata, antagonism with voriconazole against Purpureocillium lilacinum and indifference in both combinations for most of the other strains tested. These results suggest a potential role of sertraline as an adjuvant in the treatment of some of these serious mycoses.

Kocuria kristinae neuroinfection in an immunocompetent patient: a case report and review of the literature.

Few cases of disease by Kocuria kristinae have been reported, some in immunocompetent patients but mainly in immunocompromised. The current case report describes a 28-year-old female with an initial diagnosis of pituitary macroadenoma. After the initial surgery, the patient was readmitted due to tension pneumocephalus and cerebrospinal fluid (CSF) fistula. Cultures showed K. kristinae in the CSF and Candida albicans in the urine. The patient died after multiple complications. This is the first case of neuroinfection by K. kristinae in the American continent as reviewed. It was not determined as the main cause of death due to the sudden herniation, however, with active infection derived from the identification in two different samples, for this reason, we consider that it could be useful to take it as a cause of disease and a probable cause when the studies for detection of the most common pathogens have been negative.

Baricitinib plus dexamethasone compared to dexamethasone for the treatment of severe COVID-19 pneumonia: A retrospective analysis.

OBJECTIVE: We aimed to analyze clinical outcomes from patients with severe COVID-19 pneumonia that received either baricitinib plus dexamethasone or dexamethasone monotherapy. METHODOLOGY: We performed a retrospective comparative study. Data from hospitalized patients with severe COVID-19 pneumonia (saturation <93%, bilateral pulmonary infiltrates) that were treated with baricitinib plus dexamethasone or dexamethasone were collected. Our primary objective was to compare overall mortality and secondly to compare progression to mechanical ventilation and over infection rates. RESULTS: A total of 793 patients were assessed for inclusion criteria, 596 were excluded and 197 were analyzed for primary outcome: 123 in the baricitinib plus dexamethasone group and 74 in the dexamethasone monotherapy group. The mean age was 59.9 years (SD ± 14.5) and 62.1% (123/197) were male. 42.9% (85/197) of the cases required ICU admission and 25.8% (51/197) underwent invasive mechanical ventilation (IMV). Overall thirty-day mortality was 27.9% (55/197); Mortality was significantly lower in the baricitinib plus dexamethasone group compared to the dexamethasone monotherapy group (20.3% vs 40.5%, P = <.05). There was no difference in hospital acquired infections between both groups. CONCLUSION: Thirty-day mortality was significantly lower in patients with COVID-19 pneumonia treated with baricitinib plus dexamethasone versus dexamethasone monotherapy. No difference was observed in progression to invasive mechanical ventilation and hospital acquired infections.
