Bamlanivimab and Etesevimab administered in an outpatient setting for SARS-CoV-2 infection.

The early administration of anti-SARS-CoV-2 monoclonal antibodies (mAb) could decrease the risk of severe disease and the need of inpatients care. Herein, our clinical experience with Bamlanivimab/Etesevimab for the treatment of early SARS-CoV-2 infection through an outpatient service was described. Patients with confirmed COVID-19 were selected by General Practitioners (GPs) if eligible to mAb administration, according to manufacturer and AIFA (Agenzia-Italiana-del-Farmaco) criteria. If suitability was confirmed by the Multidisciplinary Team, the patient was evaluated within the next 48-72 hours. Then, all patients underwent a medical evaluation, followed by mAb infusion or hospitalization if the medical condition had worsened. Overall, from March 29th to June 4th, 2021, 106 patients with confirmed COVID-19 were identified by GPs; 26 were considered not eligible and then excluded, while 9 refused treatment. Among the 71 remaining, 6 were not treated because of worsening of symptoms soon after selection. Finally, 65 received mAb therapy. All treated patients survived. However, 2/65 developed adverse events (allergic reaction and atrial fibrillation, respectively) and 6/65 needed hospitalization. By performing univariate logistic regression analysis, diabetes was the only risk factor for hospitalization after mAb administration [aOR = 9.34, 95%CI = 1.31-66.49, p= .026]. Importantly, subjects who worsened awaiting mAb were more frequently obese (OR = 16.66, 95%CI = 1.80-153.9, p= .013) and received home corticosteroid therapy for COVID-19 (OR = 14.11, 95%CI = 1.53-129.6, p= .019). Establishing a network among GPs and COVID units could be an effective strategy to provide mAb treatment to patients with early SARS-CoV-2 infection to reduce hospitalizations and pressure on healthcare systems.

HPV in exhaled breath condensate of lung cancer patients.

BACKGROUND: A recent intriguing carcinogenetic hypothesis for lung cancer foresees its viral aetiology. The human papilloma virus (HPV) is the main virus actually recognised in the pathogenesis of lung cancer. The aim of this study was to investigate, for the first time to our knowledge, the presence of HPV in the exhaled breath condensate (EBC) of lung cancer patients. MATERIALS AND METHOD: We enrolled 89 patients affected by lung cancer and 68 controls. HPV infections were investigated in their EBC, paired bronchial brushing and neoplastic lung tissue through genotyping. RESULTS: We were able to detect HPV in the EBC, bronchial brushing and neoplastic lung tissue. We described the presence of an HPV infection in 16.4% of the subjects affected by non-small cell lung cancer, but in none of the controls. HPV 16 and 31 turned out to be the most widespread genotypes. The HPV positivity in airways as well as in the smoking habit was seen to independently increase the individual's susceptibility to developing lung cancer. CONCLUSION: When summing up, we demonstrated the possibility to identify an HPV infection in the EBC of lung cancer patients; further, we supported the notion that the EBC is a suitable tool to study airway colonisation. That being said, although further studies are needed to confirm our results, we retain the study of HPV in EBC to be very interesting in terms of future programmes involving lung-cancer screening.

Pro-inflammatory M1/Th1 type immune network and increased expression of TSG-6 in the eutopic endometrium from women with endometriosis.

OBJECTIVE: The study aimed to explore the type 1 and type 2 cytokines expression in the endometrium from women affected by endometriosis compared to controls. The expression of TSG-6, a multifunctional protein involved in several inflammatory disease, was also evaluated. Study Design SETTING: Experimental clinical study. PATIENTS: 10 patients affected by endometriosis and 11 controls. INTERVENTIONS: Patients underwent to an ultrasound transvaginal examination and a diagnostic hysteroscopy in order to exclude any uterine abnormality. All patients underwent endometrial biopsy using a Novak's curette. MAIN OUTCOME MEASURES: The endometrial expression of type 1 (IL- 1 ß TNF-α, IL-8) and type 2 (IL-10) cytokines, and of TSG-6 was evaluated by immunohistochemistry and by real time PCR. The expression of TSG-6 was confirmed by western blot. RESULTS: Results of PCR analysis and of immunohistochemistry revealed an increased expression of IL-1ß, TNF-α, IL-8 and of TSG-6 in the endometrium of endometriosic patients. IL-10 expression did not show any difference. CONCLUSIONS: An increased expression of pro-inflammatory type 1 cytokines was demonstrated in the endometrium from endometriosic patients, suggesting an endometrial environment harmful for implantation due to the prevalence of Th1 related immunity. An increased expression of TSG-6 was also demonstrated for the first time. Our findings concur to better define the inflammatory imbalance and the abnormal endometrial receptivity, reported in literature, of the eutopic endometrium of women affected by endometriosis.

Phase I/II study of gemcitabine plus vinorelbine as first-line chemotherapy of non-small-cell lung cancer.

PURPOSE: To determine the maximum-tolerated dose of gemcitabine when combined with a fixed dose of vinorelbine in the treatment of non-small-cell lung cancer (NSCLC) and to evaluate in a phase II trial the activity of this combination. PATIENTS AND METHODS: Sixty-eight patients with stage IIIB/IV NSCLC were treated with vinorelbine at fixed dose of 30 mg/m(2) intravenously and gemcitabine at increasing dose levels from 800 to 1,500 mg/m(2) intravenously on days 1 and 8 every 3 weeks. RESULTS: In phase I, dose-limiting toxicity occurred at the dosage of 1,500 mg/m(2) gemcitabine, with three of five patients developing grade 4 thrombocytopenia. In phase II, with gemcitabine at 1,200 mg/m(2), 19 (36%) of 52 assessable patients responded. Objective response was observed in 11 (39%) of 28 patients with stage IIIB disease and in eight (33%) of 24 patients with stage IV. The median time to progression was 29 weeks (range, 2 to 41 weeks; 35 weeks and 16 weeks for stages IIIB and IV, respectively), and median survival was 54 weeks (range, 2 to 84+ weeks; 63 weeks and 42 weeks for stages IIIB and IV, respectively). One-year survival was 64% for patients with stage IIIB disease and 29% for those with stage IV. Clinical benefit response was observed in 29 (59%) of 49 assessable patients. Grade 4 leukopenia and thrombocytopenia were uncommon (6% and 8% of cases, respectively); however, grade 3/4 leukothrombocytopenia occurred more frequently in patients aged more than 70 years (52% and 24%, respectively). CONCLUSION: The combination of vinorelbine and gemcitabine is effective and tolerable in the treatment of NSCLC, thus deserving randomized trials with cisplatin combination regimens.

Cisplatin, gemcitabine, and vinorelbine combination therapy in advanced non-small-cell lung cancer: a phase II randomized study of the Southern Italy Cooperative Oncology Group.

PURPOSE: In a previous phase I study cisplatin (CDDP), gemcitabine (GEM), and vinorelbine (VNR) combination therapy was safe and very active in patients with non-small-cell lung cancer (NSCLC). This study was aimed at better defining the activity and toxicity of this regimen. PATIENTS AND METHODS: One hundred eleven chemotherapy-naive patients, age < or = 70 years, with stage IIIB or IV NSCLC and a performance status of 0 or 1 (Eastern Cooperative Oncology Group scale) were randomized to two treatment arms. Patients on arm A received CDDP 50 mg/m2, GEM 1,000 mg/m2, and VNR 25 mg/m2 on days 1 and 8 of an every-3-weeks cycle (57 patients). Patients on arm B received CDDP 80 mg/m2, epirubicin 80 mg/m2, and vindesine 3 mg/m2, all delivered on day 1 every 4 weeks, plus lonidamine orally 150 mg three times daily (54 patients). In December 1996, randomization was stopped early, and an additional 30 patients were treated with the experimental regimen to obtain a more accurate estimation of its activity rate. RESULTS: Among 87 patients who received the CDDP-GEM-VNR combination, four complete responses (CRs) and 46 partial responses (PRs) were observed, for an overall response rate of 57% (95% confidence interval [CI], 46% to 68%). Two CRs and 18 PRs were recorded among 54 patients on arm B, giving a 37% activity rate (95% CI , 24% to 51%). After a median follow-up duration of 19 months, the median progression-free and overall survival durations were 32 and 50 weeks in arm A, and 18 and 33 weeks in arm B, respectively. World Health Organization grade 3 to 4 neutropenia and thrombocytopenia occurred in 46% and 14% of patients in arm A and in 22% and 11% of those in arm B, respectively. Severe nonhematologic toxicity was uncommon in both arms. CONCLUSION: The CDDP-GEM-VNR combination is a highly effective treatment for patients with advanced NSCLC and has a manageable toxicity. A phase III trial comparing this new combination with both CDDP-VNR and CDDP-GEM regimens is underway.

Cisplatin, gemcitabine, and paclitaxel in locally advanced or metastatic non-small-cell lung cancer: a phase I-II study. Southern Italy Cooperative Oncology Group.

PURPOSE: Because both cisplatin-paclitaxel and cisplatin-gemcitabine combinations are generally considered to be among the most active regimens in non-small-cell lung cancer (NSCLC) patients, this study aimed to determine the maximum-tolerated dose (MTD) of paclitaxel when combined with fixed doses of cisplatin and gemcitabine in advanced NSCLC patients and aimed to define the therapeutic activity of this new regimen. PATIENTS AND METHODS: From October 1996 to September 1998, 75 patients with stage IIIB-IV NSCLC, who were either chemotherapy-naive (65 patients) or who had been pretreated (10 patients), received fixed doses of cisplatin (50 mg/m(2)) and gemcitabine (1,000 mg/m(2)) and escalating doses of paclitaxel in a 1-hour infusion, all on days 1 and 8, every 3 weeks. RESULTS: Five different paclitaxel doses were tested, for a total of 275 cycles delivered. The escalation was stopped at the paclitaxel dose of 75 mg/m(2) in pretreated patients, whereas it continued to 150 mg/m(2) in chemotherapy-naive patients. A total of 65 chemotherapy-naive patients were treated. A paclitaxel dose of 125 mg/m(2) was recommended for phase II, and a total of 39 patients were treated at this level, for a total of 158 cycles delivered. No treatment-related deaths occurred. Five patients were hospitalized because of sepsis, and packed RBC transfusion was required in 13 patients. Grade 4 neutropenia and thrombocytopenia occurred in 23 (31%) and eight (11%) patients, respectively. Overall, 74 of the 75 patients were assessable for response. Four complete (CR) and 38 partial (PR) responses were recorded, for an overall response rate (ORR) of 57%. Three of the ten pretreated patients achieved a PR, compared with four CRs and 35 PRs in the 64 chemotherapy-naive patients (ORR, 61%). Thirty-eight of 39 patients included in phase II were assessable for response and quality of life (QOL) (one patient's disease was not measurable). Two CRs and 24 PRs were recorded in this group, for an ORR of 68% (95% confidence interval, 51% to 82%). The QOL score improved in 27 of 38 (71%) patients. The median survival time was 15 months in the 65 chemotherapy-naive patients, but it had not yet been reached in the 39 patients included in phase II, for whom the 1-year projected survival was 70%. CONCLUSION: The cisplatin-gemcitabine-paclitaxel combination is a feasible and well-tolerated approach in advanced NSCLC patients. Both a major response and a QOL improvement can be obtained in a high proportion of patients, with a median survival time exceeding 1 year. A phase III trial comparing this combination with other effective regimens is under way.

Accelerated neoadjuvant chemotherapy of non-small cell lung cancer (NSCLC).

Thirty patients with marginally resectable stage IIIA or stage IIIB NSCLC were treated with cisplatin (80 mg/ m(2)/i.v./dl), ifosfamide (4,000 mg/m(2)/i.v./dl) and vinorelbine (30 mg/m(2)/i.v./dl) plus G-CSF 300 mu g/s.c. on days 7-12 every 14 days for three cycles before surgery. In 26 evaluable patients, the radiographically assessed response rate to chemotherapy was 77% (8% complete). Three septic deaths (10%) occurred in spite of G-CSF and 1 patient refused to continue after the first cycle. Thoracothomy was performed in 23 patients including 19 complete resections. At 15 months median follow-up (range 10-22+), 11/19 (57%) completely resected patients relapsed. The overall median time to treatment failure was 11 months (range 0-17). Actuarial survival probability at 12, 18 and 24 months are 56%, 43% and 36%, respectively. In conclusion, the combination of cisplatin, ifosfamide and vinorelbine in full doses at a 14 day interval (accelerated chemotherapy) was very effective in neoadjuvant NSCLC setting. Nevertheless, relevant toxicity was demonstrated with a 10% death rate probably due to the overlapping toxicity of chemotherapy cycles, suggesting the need for a more intense supportive care or longer interval between cycles.

Interleukin-6 is increased in breath condensate of patients with non-small cell lung cancer.

Despite recent advances in the diagnosis and treatment of non-small cell lung cancer (NSCLC), most patients still present with advanced stage disease at the time of diagnosis. Recent studies suggest that IL-6 is involved in the development of lung cancer. The aim of the present study was to investigate whether the measurement of IL-6 levels in the breath condensate of NSCLC patients could be used to bring forward the moment of diagnosis and to monitor the progression of the disease. Twenty patients with histological evidence of NSCLC (14 men and 6 women, age 63+/-8 years) and 15 healthy controls (8 men and 7 women, age 45+/-6 years) were enrolled in the study. IL6 was measured in the exhaled breath condensate of patients and controls by means of a specific enzyme immunoassay kit. Higher concentrations of exhaled IL-6 were found in NSCLC patients (9.6+/-0.3 pg/mL) than in controls (3.5+/-0.2 pg/mL). A statistically significant difference was observed between patients with NSCLC at different stages: higher concentrations of IL-6 (10.9+/-0.5 pg/mL) were found in patients with metastatic disease than in those with stage III (9.7+/-0.4 pg/mL), stage II (8.9+/-0.3 pg/mL) and stage I disease (7.9+/-0.3 pg/mL). These findings suggest that the measurement of IL-6 in the breath condensate of patients with NSCLC could be proposed as a parameter to take into account in early diagnosis and disease monitoring.
