RESUMO
INTRODUCTION: Mortality from candidemia is higher in elderly population than in younger patients, which may be related to suboptimal management. The aim of the present study is to evaluate adherence to the recommendations for the clinical management of candidemia in a population over 75 years before and after implementing specific training. PATIENTS AND METHODS: We recorded retrospectively data from candidemia episodes in elderly patients during two periods of time: 2010-2015 years (before training) and 2017-2022 years (after training), as well as adherence to the recommendations of the clinical practice guidelines, mortality and consultation to infectious disease specialists. RESULTS: Forty-five episodes of candidemia were recorded in the first period and 29 episodes in the second period. A better compliance to the recommendations of the clinical practice guidelines was observed in the second period: echocardiogram performance (75.9% vs. 48.9% p = .021), fundoscopy (65.5% vs. 44.4% p = .076), follow-up blood cultures (72.4% vs. 42.2% p = .011), removal of central venous catheter (80% vs. 52.9% p = .080) and adequate antifungal treatment (82.6% vs. 52.6% p = .018). A trend towards lower mortality was observed during the second period (27.6% vs. 44.4% p = .144). CONCLUSION: The improvement of knowledge of clinical guidelines on candidemia and the participation of infectious disease specialists may increase the quality of care in elderly patients with candidemia. It would be necessary to enlarge the sample size to evaluate the real impact of this intervention on mortality.

BACKGROUND: Cobicistat, dolutegravir and rilpivirine are all modest inhibitors of proximal tubular creatinine secretion (IPTCrS) and hence a moderate and early non-progressive creatinine estimated glomerular filtration rate (Cr-eGFR) reduction has been observed in clinical trials. Data regarding the impact of combination of those drugs on Cr-eGFR, in the clinical practice, are scarcely known. METHODS: Changes in Cr-eGFR after starting darunavir/cobicistat alone or in combination with dolutegravir and/or rilpivirine were studied in a nationwide retrospective cohort study of consecutive HIV-infected patients initiating darunavir/cobicistat. The relationship between Cr-eGFR changes over time and the use of darunavir/cobicistat alone or darunavir/cobicistat plus dolutegravir and/or rilpivirine adjusted by different HIV patient's characteristics, socio-demographics, HIV severity and use of tenofovir concomitant medication other than antiretrovirals was explored through univariate and multivariate analyses. RESULTS: The analysis included 725 patients. At 48 weeks, the combination of two or more IPTCrS (darunavir/cobicistat with rilpivirine and/or dolutegravir) was associated with higher decreases in Cr-eGFR [adjusted median difference (±SD) -3.5 ± 1.6 (95% CI -6.6 to -0.3), P = 0.047], and a decrease up to or higher than 15 mL/min/1.73 m2 was more frequent [adjusted OR 3.233 (95% CI 1.343-7.782), P = 0.009], with respect to darunavir/cobicistat alone. The Cr-eGFR changes between darunavir/cobicistat and darunavir/cobicistat with rilpivirine and/or dolutegravir showed more significant decreases in patients taking two or more IPTCrS at 12, 24 and 48 weeks. (ClinicalTrials.gov: NCT03042390). CONCLUSIONS: Concomitant use of darunavir/cobicistat plus IPTCrS dolutegravir, rilpivirine, or both produced an additive effect in the expected Cr-eGFR decrease.

Background: Although switching antiretroviral therapy (ART) in people with human immunodeficiency virus experiencing insomnia due to dolutegravir-related neurotoxicity is well founded upon evidence, there is a lack of proof in regard to the outcome of stopping dolutegravir-based ART in people without insomnia but reporting poor sleep quality. Methods: This is a randomized, multicenter, open-label study to evaluate the reversibility of patient-reported sleep disturbances in patients on dolutegravir/lamivudine/abacavir without insomnia after switching to darunavir/cobicistat/emtricitabine/tenofovir alafenamide. The participants were randomized to switch ART at baseline or at week 4 and then completed 8 weeks of darunavir/cobicistat/emtricitabine/tenofovir alafenamide. Our primary objective was to compare changes in sleep quality between arms at week 4. Secondary objectives were to compare changes in mood and neuropsychiatric symptoms (NS) at week 4 and 4 and 8 weeks after switching to darunavir/cobicistat/emtricitabine/tenofovir alafenamide. The participants completed a survey, including the Pittsburgh Sleep Quality Index (PSQI), the Hospital Anxiety and Depression scale (HADS), and specific questions to explore NS, at each visit to assess those objectives. Results: We included 72 participants. The results show that study arms were similar at baseline; however, at week 4, PSQI scores remained unchanged with dolutegravir/lamivudine/abacavir, whereas patients improved significantly after switching to darunavir/cobicistat/emtricitabine/tenofovir alafenamide. Similar differences between arms were also observed in HADS and NS changes. At weeks 4 and 8 after all participants switched to darunavir/cobicistat/emtricitabine/tenofovir alafenamide, we have observed significant improvements in PSQI and HAD scores and in NS. Conclusions: In patients reporting subclinical sleep disturbances without insomnia, switching from dolutegravir/lamivudine/abacavir to darunavir/cobicistat/emtricitabine/tenofovir alafenamide was associated with better sleep quality and improvements in mood and NS.
RESUMO
We present the case of a patient with multiple comorbidities, including cirrhosis, poorly controlled diabetes mellitus and HIV infection, who was diagnosed with skin and soft-tissue infection of right lower limb. Outcome was poor after prescribing standard antibiotic therapy, and we finally obtained isolation of Candida tropicalis in cultures of infected tissue. The patient's condition improved after antifungal treatment was started, and he could be discharged with oral therapy. Here, we report the literature's first case of cellulitis provoked by C. tropicalis in a patient with cirrhosis.

BACKGROUND: Despite evidence shown of dolutegravir (DTG)-related neurotoxicity, which may be more common when combined with abacavir (ABC), its reversibility has not been explored in a clinical trial. METHODS: We conducted a randomized, multicenter, open-label, pilot trial to evaluate the reversibility of patient-reported neuropsychiatric symptoms, developed or worsened on DTG/ABC/lamivudine (DTG/ABC/3TC), in virologically suppressed patients switched to cobicistat-boosted-elvitegravir/emtricitabine/tenofovir-alafenamide (EVG/COBI/FTC/TAF). Participants were randomized to immediate switch (baseline) or to defer switch (week 4), and then all completed 24 weeks of follow up on EVG/COBI/FTC/TAF. At each visit, participants completed Pittsburgh Sleep Quality Index (PSQI) and Hospital Anxiety and Depression (HAD) scales and were interviewed about 11 neuropsychiatric symptoms potentially related with DTG through a questionnaire. At baseline and at the end of follow up, they also performed neurocognitive testing. Our primary objective was to compare changes in neuropsychiatric symptoms and PSQI and HAD scales between arms at week 4. Secondary objectives were to evaluate changes in neuropsychiatric symptoms and PSQI and HAD scales at weeks 4, 12, and 24 after switching to EVG/COBI/FTC/TAF and in neurocognitive performance and magnetic resonance imaging biomarkers at end of follow up. RESULTS: Thirty-eight participants were included. Study arms were similar at baseline. At week 4, neuropsychiatric symptoms and PSQI and HAD scores remained unchanged in participants receiving DTG/ABC/3TC and improved significantly in participants receiving EVG/COBI/FTC/TAF. These significant improvements were also observed at weeks 4, 12, and 24 after all participants switched to EVG/COBI/FTC/TAF. In addition, global neurocognitive performance improved (NPZ-7) after switching to EVG/COBI/FTC/TAF. CONCLUSIONS: Neuropsychiatric symptoms in patients on DTG/ABC/3TC could resolve or improve after switching to EVG/COBI/FTC/TAF.
RESUMO
Coinfection with hepatitis C virus (HCV) influences HIV reservoir size. However, it is unknown whether this coinfection also induces a higher provirus transcription. Viral transcription is promoted by synergy between cellular factors such as NF-κB and the viral regulator Tat. The impact of HCV coinfection on HIV provirus transcription was analyzed in resting (r)CD4 T+ cells (CD3+CD4+CD25-CD69-HLADR-) and rCD4 T cells-depleted PBMCs (rCD4 T- PBMCs) from a multicenter cross-sectional study of 115 cART-treated HIV patients: 42 HIV+/HCV+ coinfected individuals (HIV+/HCV+), 34 HIV+ patients with HCV spontaneous clearance (HIV+/HCV-) and 39 HIV patients (HIV+). Viral transcription was assessed in total RNA through the quantification of unspliced, single spliced, and multiple spliced viral mRNAs by qPCR. Linear correlations between viral reservoir size and viral splicing were determined. A 3-fold increase of multiple spliced transcripts in rCD4 T+ cells of HIV+/HCV+ patients was found compared to HIV+ individuals (p < 0.05). As Tat is synthesized by multiple splicing, the levels of Tat were also quantified in these patients. Significant differences in single and multiple spliced transcripts were also observed in rCD4 T- PBMCs. Levels of multiple spliced mRNAs were increased in rCD4 T+ cells isolated from HIV+/HCV+ subjects, which could indicate a higher Tat activity in these cells despite their resting state.
