ABSTRACT

INTRODUCTION: Until recently, biological therapy for hidradenitis suppurativa was limited to anti-tumor necrosis factor (TNF) blockade with adalimumab (ADA). However, not all patients respond to treatment with ADA. This highlighted the need for more therapeutic options. Interleukin (IL)-17/T-helper 17 (Th17) axis may play an important role in the pathophysiology of HS. Recently, the IL-17A inhibitor secukinumab, which targets IL-17A specifically and prevents it from interacting with the IL-17 receptor, has been FDA-approved for HS. AREAS COVERED: Secukinumab, represents a novel therapeutic strategy in HS management. An overview of structural and pharmacological characteristics is provided. Described efficacy in clinical trials and case reports and safety data from is presented. EXPERT OPINION: As response to anti-TNFas is lost over time, secukinumab has provided an alternative HS treatment option in clinical practice. Overall, secukinumab has shown good efficacy and a favorable side effect profile in HS clinical trials but may be avoided in patients with inflammatory bowel disease. Long-term and real-life data on the use of secukinumab are essential for improving decision-making in HS therapy.

ABSTRACT

The isolation of a pan-echinocandin-resistant Candida parapsilosis strain (anidulafungin, caspofungin, micafungin and rezafungin EUCAST MICs > 8 mg/L) from urine of a patient following prolonged exposure to echinocandins (38 days of micafungin followed by 16 days of anidulafungin) is described. The isolate harbored the novel alteration F652S in the hotspot 1 region of fks1. Isogenic C. parapsilosis bloodstream isolates collected up to 1.5 months earlier from the same patient were susceptible to echinocandins (anidulafungin, caspofungin and micafungin EUCAST MICs 1−2, 1 and 1 mg/L, respectively) and contained wild-type FKS1 sequences. This is the first report of pan-echinocandin resistance in C. parapsilosis associated with an aminoacid change in hotspot 1 region of fks1.

ABSTRACT

In a recent study of our group with the acronym ACTIVATE, Bacillus Calmete-Guérin (BCG) vaccination reduced the occurrence of new infections compared to placebo vaccination in the elderly. Most benefit was found for respiratory infections. The ACTIVATE-2 study was launched to assess the efficacy of BCG vaccination against coronavirus disease 2019 (COVID-19). In this multicenter, double-blind trial, 301 volunteers aged 50 years or older were randomized (1:1) to be vaccinated with BCG or placebo. The trial end points were the incidence of COVID-19 and the presence of anti-severe acute respiratory syndrome coronavirus 2 (anti-SARS-CoV-2) antibodies, which were both evaluated through 6 months after study intervention. Results revealed 68% relative reduction of the risk to develop COVID-19, using clinical criteria or/and laboratory diagnosis, in the group of BCG vaccine recipients compared with placebo-vaccinated controls, during a 6-month follow-up (OR 0.32, 95% CI 0.13-0.79). In total, eight patients were in need of hospitalization for COVID-19: six in the placebo group and two in the BCG group. Three months after study intervention, positive anti-SARS-CoV-2 antibodies were noted in 1.3% of volunteers in the placebo group and in 4.7% of participants in BCG-vaccinated group. These data indicate that BCG vaccination confers some protection against possible COVID-19 among patients older than 50 years with comorbidities. BCG vaccination may be a promising approach against the COVID-19 pandemic.

ABSTRACT

Early increase of soluble urokinase plasminogen activator receptor (suPAR) serum levels is indicative of increased risk of progression of coronavirus disease 2019 (COVID-19) to respiratory failure. The SAVE-MORE double-blind, randomized controlled trial evaluated the efficacy and safety of anakinra, an IL-1α/ß inhibitor, in 594 patients with COVID-19 at risk of progressing to respiratory failure as identified by plasma suPAR ≥6 ng ml-1, 85.9% (n = 510) of whom were receiving dexamethasone. At day 28, the adjusted proportional odds of having a worse clinical status (assessed by the 11-point World Health Organization Clinical Progression Scale (WHO-CPS)) with anakinra, as compared to placebo, was 0.36 (95% confidence interval 0.26-0.50). The median WHO-CPS decrease on day 28 from baseline in the placebo and anakinra groups was 3 and 4 points, respectively (odds ratio (OR) = 0.40, P < 0.0001); the respective median decrease of Sequential Organ Failure Assessment (SOFA) score on day 7 from baseline was 0 and 1 points (OR = 0.63, P = 0.004). Twenty-eight-day mortality decreased (hazard ratio = 0.45, P = 0.045), and hospital stay was shorter.

ABSTRACT

INTRODUCTION: The anti-inflammatory effect of macrolides prompted the study of oral clarithromycin in moderate COVID-19. METHODS: An open-label non-randomized trial in 90 patients with COVID-19 of moderate severity was conducted between May and October 2020. The primary endpoint was defined at the end of treatment (EOT) as no need for hospital re-admission and no progression into lower respiratory tract infection (LRTI) for patients with upper respiratory tract infection and as at least 50% decrease of the respiratory symptoms score without progression into severe respiratory failure (SRF) for patients with LRTI. Viral load, biomarkers, the function of mononuclear cells and safety were assessed. RESULTS: The primary endpoint was attained in 86.7% of patients treated with clarithromycin (95% CIs 78.1-92.2%); this was 91.7% and 81.4% among patients starting clarithromycin the first 5 days from symptoms onset or later (odds ratio after multivariate analysis 6.62; p 0.030). The responses were better for patients infected by non-B1.1 variants. Clarithromycin use was associated with decreases in circulating C-reactive protein, tumour necrosis factor-alpha and interleukin (IL)-6; by increase of production of interferon-gamma and decrease of production of interleukin-6 by mononuclear cells; and by suppression of SARS-CoV-2 viral load. No safety concerns were reported. CONCLUSIONS: Early clarithromycin treatment provides most of the clinical improvement in moderate COVID-19. TRIAL REGISTRATION: ClinicalTrials.gov, NCT04398004.

ABSTRACT

AIM: To estimate the cost per patient for hepatocellular carcinoma in Greece, a setting that is currently facing financial constraints. BACKGROUND: Hepatocellular carcinoma patient management strategies are associated with significant costs. Despite this, patient level data on healthcare resource use and cost-of-illness analyses of hepatocellular carcinoma remain rather scarce in the international literature. METHODS: 123 patients diagnosed with hepatocellular carcinoma and followed in a specialised clinic of a tertiary hospital in Greece formed the basis of the analysis. Detailed resource use data were derived from the medical records of each patient. Data were recorded from the first encounter of the patient with the facility until a fatal endpoint or until the last day of follow up. Patients that were lost to follow-up were excluded from the analysis. Calculations follow a third-party payer perspective, according to official prices and tariffs. RESULTS: The average cost per patient was estimated at 12,119.1 Euros (SD: 14,670.3) (21,375.1 PPP USD) for the average follow-up period and 10,241.5 Euros (18,063.5 PPP USD) per year. Median costs per month of follow-up according to underlying disease were 1,218.1, 1,376.8, 1,521.3 and 686.9 Euros (2,148.4, 2,428.3, 2,683.2 and 1,211.5 PPP USD) for patients with alcoholic steatohepatitis, hepatitis B, hepatitis C and non-alcoholic fatty liver disease, respectively. CONCLUSION: Hepatocellular carcinoma represents a heavy toll, both from the clinical as well as from the economic perspective, especially for a setting in "dire straits". Interventions towards reducing the incidence and, subsequently, the cost of HCC are imperative.

ABSTRACT

BACKGROUND: The pneumonia of COVID-19 illness has often a subtle initial presentation making mandatory the use of biomarkers for evaluation of severity and prediction of final patient disposition. We evaluated the use of hydrogen sulfide (H2S) for the outcome of COVID-19 pneumonia. PATIENTS AND METHODS: We studied 74 patients with COVID-19. Clinical data were collected, and survival predictors were calculated. Blood was collected within 24 h after admission (day 1) and on day 7. H2S was measured in sera by monobromobimane derivation followed by high-performance liquid chromatography and correlated to other markers like procalcitonin and C-reactive protein (CRP). Tumor necrosis factor alpha and interleukin (IL)-6 were also measured in serum. RESULTS: Survivors had significantly higher H2S levels on days 1 and 7 after admission. A cut-off point of 150.44 µM could discriminate survivors from non-survivors with 80% sensitivity, 73.4% specificity, and negative predictive value 95.9%. Mortality after 28 days was 32% with admission levels lower than or equal to 150.44 µM and 4.1% with levels above 150.44 µM (P: 0.0008). Mortality was significantly greater among patients with a decrease of H2S levels from day 1 to day 7 greater than or equal to 36% (p: 0.0005). Serum H2S on day 1 was negatively correlated with IL-6 and CRP and positively correlated with the absolute lymphocyte count in peripheral blood. CONCLUSION: It is concluded that H2S is a potential marker for severity and final outcome of pneumonia by the SARS-CoV-2 coronavirus. Its correlation with IL-6 suggests anti-inflammatory properties.

ABSTRACT

Cases of sexual reassignment in Greco-Roman antiquity, presenting as a pubertal female to male gender transformation, are described in the "classical"literature. Textual evidence concerning a case of androgynism, garnered by Diodorus Siculus, among other similar accounts, as an odd story of gender dispute in a court of justice, is provided in the present study. A medical interpretation of the data pertaining to this case has been attempted and is herein reported. The spontaneous virilization and post-pubertal gender inversion of the specific individual appears to have been caused by a defect either in 5α-reductase type 2 or in 17ß hydroxysteroid dehydrogenase genes and consequent deficient enzymatic activity.
