Effect of Combination Therapy of Hydroxychloroquine and Azithromycin on Mortality in Patients With COVID‐19

Conflicting evidence regarding the use of hydroxychloroquine (HCQ) and azithromycin for the treatment of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection do exist. We performed a retrospective single‐center cohort study including 377 consecutive patients admitted for pneumonia related to coronavirus disease 2019 (COVID‐19). Of these, 297 were in combination treatment, 17 were on HCQ alone, and 63 did not receive either of these 2 drugs because of contraindications. The primary end point was in‐hospital death. Mean age was 71.8 ± 13.4 years and 34.2% were women. We recorded 146 deaths: 35 in no treatment, 7 in HCQ treatment group, and 102 in HCQ + azithromycin treatment group (log rank test for Kaplan–Meier curve P < 0.001). At multivariable Cox proportional hazard regression analysis, age (hazard ratio (HR) 1.057, 95% confidence interval (CI) 1.035–1.079, P < 0.001), mechanical ventilation/continuous positive airway pressure (HR 2.726, 95% CI 1.823–4.074, P < 0.001), and C reactive protein above the median (HR 2.191, 95% CI 1.479–3.246, P < 0.001) were directly associated with death, whereas use of HCQ + azithromycin (vs. no treatment; HR 0.265, 95% CI 0.171–0.412, P < 0.001) was inversely associated. In this study, we found a reduced in‐hospital mortality in patients treated with a combination of HCQ and azithromycin after adjustment for comorbidities. A large randomized trial is necessary to confirm these findings.

The severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection is spreading worldwide since December 2019 and still no proven effective therapy has been found. First therapy proposed to treat coronavirus disease 2019 (COVID‐19) has been the association of lopinavir‐ritonavir, a protease inhibitor approved for HIV infection. However, Cao et al. observed no benefit comparing lopinavir‐ritonavir treatment of hospitalized patients with severe COVID‐19, ¹ and this treatment is currently not recommended. Currently, only remdesivir has been approved for COVID‐19 treatment, as it reduced recovery time by 4 days in 1,063 patients randomized to either remdesivir 200 mg loading dose followed by 100 mg daily or placebo for up to 10 days ² with a similar rate of adverse events between the 2 groups. ³ However, no effect on in‐hospital mortality was found.Chloroquine and its derivative hydroxychloroquine (HCQ), based on few preclinical studies, have also been proposed as therapies for COVID‐19. A Chinese randomized trial in patients with mild disease showed a significantly shorter recovery time in the group treated with HCQ vs. the standard of care along with a radiological improvement. ⁴ Differently, a retrospective study performed in the United States Veterans Health Administration medical centers found an increased mortality associated with the treatment with HCQ. ⁵ Moreover, an observational study has shown no significant association between HCQ use and risk of intubation or death. ⁶ Furthermore, a recent randomized controlled trial has found no differences between patients treated with HCQ plus the standard of care vs. the standard of care alone in terms of virus elimination. ⁷ On the basis of a very small nonrandomized study, azithromycin has been proposed as possible treatment in association with HCQ. ⁸ Azithromycin, is an antibiotic belonging to the class of macrolides, with some proven efficacy in acute respiratory distress syndrome. ⁹ , ¹⁰ It is known to have immunomodulatory properties through the polarization of macrophages toward the reparative state ¹¹ and the reduction in the production of pro‐inflammatory cytokines, such as IL‐8, IL‐6, TNF alpha, ¹² and iNOS expression. ¹³ Recently, two large retrospective studies evaluating in‐hospital mortality associated with the use of the combination of HCQ and azithromycin (or another macrolide, such as clarithromycin), have shown no benefits. ¹⁴ Despite the lack of a proven clinical efficacy and some concerns regarding the possible QT prolongations caused by the association of HCQ and azithromycin, ¹⁵ given the low price and the wide availability, the association of these two drugs has become the most used treatment in patients with moderate‐severe COVID‐19.Because of the urgent need to find answers to the many questions posed by the fight to SARS‐CoV2 infection and some negative evidences regarding the use of HCQ, we here propose a retrospective observational study to assess the efficacy of the combination of HCQ plus azithromycin for hospitalized patients with medium‐severe COVID‐19.     

Necrotic erythema nodosum reaction associated with histological alterations of Lucio’s phenomenon

Patients with lepromatous or borderline leprosy may present two types of vasculonecrotic reactions: Lucio’s phenomenon (LP) and necrotic erythema nodosum leprosum (nENL). These are serious conditions, which mostly lead to life-threatening infectious and thrombotic complications. The authors report the case of a patient with leprosy recurrence associated with an atypical type II reaction with LP characteristics on histopathology.

Videolaparoscopic microwave ablation in patients with HCC at a European high-volume center: Results of 815 procedures

Background: Videolaparoscopic (VL) microwave ablation (MWA) is not included in most of the international guidelines as a therapeutic option for hepatocellular carcinoma (HCC). Aim of this study was to assess the safety of VL MWA in patients with HCC for whom resection or percutaneous ablation is unsuitable. Methods: A retrospective analysis was performed on a prospective database of patients with HCC treated with VL MWA at our institution from 2009 to 2016. Patient demographics, operational characteristics, and complications were recorded. Statistical analysis was performed to identify safety profile, overall survival and recurrence rate. Results: A total of 815 VL MWA were performed in 674 patients with a mean age of 64 years. Patients had a mean Model for End-stage Liver Disease score of 10 (±3); 32.8% were Child B, 44.1% Barcelona Clinic Liver Cancer B-C. Perioperative mortality was 0.4%. Overall morbidity was 30.8%, with Dindo-Clavien complications ≥3 in 2%. The median length of stay was 2 days. In 43.1% VL MWA was the first-line therapy. Overall 1-, 3-, and 5-year survival rates were 81.9%, 54.9%, and 35.9%. Conclusions: The present is the largest series of VL ablation and the bigger number of patients with HCC treated with MW reported nowadays. It confirms the safety of a minimally invasive procedure for patients with HCC when resection or percutaneous ablation is not feasible.     

A Novel Nomogram to Identify Candidates for Extended Pelvic Lymph Node Dissection Among Patients with Clinically Localized Prostate Cancer Diagnosed with Magnetic Resonance Imaging-targeted and Systematic Biopsies

Background

Available models for predicting lymph node invasion (LNI) in prostate cancer (PCa) patients undergoing radical prostatectomy (RP) might not be applicable to men diagnosed via magnetic resonance imaging (MRI)-targeted biopsies.

Neoadjuvant therapy in the treatment of hilar cholangiocarcinoma:Review of the literature

Cholangiocarcinoma(CCA) is a malignant tumor of the biliary system and includes, according to the anatomical classification, intra hepatic CCA(iCCA),hilar CCA(hCCA) and distal CCA(dCCA). Hilar CCA is the most challenging type in terms of diagnosis, treatment and prognosis. Surgery is the only treatment possibly providing long-term survival, but only few patients are considered resectable at the time of diagnosis. In fact, tumor's extension to segmentary or subsegmentary biliary ducts, along with large lymph node involvement or intrahepatic metastases, precludes the surgical approach. To achieve R0 margins is mandatory for the disease-free survival and overall survival. In case of unresectable locally advanced hCCA, radiochemotherapy(RCT) as neoadjuvant treatment demonstrated to be a therapeutic option before either hepatic resection or liver transplantation. Before liver surgery, RCT is believed to enhance the R0 margins rate. For patients meeting the Mayo Clinic criteria, RCT prior to orthotopic liver transplant(OLT) has proved to produce acceptable 5-years survivals. In this review, we analyze the current role of neoadjuvant RCT before resection as well as before OLT.
