Evaluating the Effects of Umifenovir Compared to Lopinavir/Ritonavir in the Management of Patients with COVID-19: A Randomized Controlled Trial

Background. Due to the lack of specific safe medications for the treatment of COVID-19, medications used for other similar conditions are being tested to alleviate the condition of COVID-19 patients, resulting in acceptable outcomes in some cases. Umifenovir (Arbidol®) is used to treat influenza viruses by inhibiting the fusion of the virus with the host cell. According to previous findings, umifenovir may inhibit SARS-CoV-2 infection by interfering with the release of SARS-CoV-2 from inside the cell. This study aimed to determine the effects of umifenovir, a fusion inhibitor, versus lopinavir/ritonavir in treating patients with COVID-19. Methods. This study was a randomized controlled trial consisting of 90 confirmed COVID-19 patients divided into the lopinavir/ritonavir group and the umifenovir group. The lopinavir/ritonavir group received 100/25 mg twice, while the umifenovir group was given 200 mg thrice a day, in both groups, for seven days. Outcomes included mortality rate and the need for mechanical ventilation or intensive care unit admission. Length of stay in the hospital and ICU and the lab tests trend were also assessed. Results. The mortality rate and the need for admission to the ICU were significantly lower in the umifenovir group (8% vs. 27.5%; P-value = 0.02). Moreover, The levels of white blood cells were also lower in the umifenovir group than in the control group by day 10 (6.2 (5.3-7.4) vs. 10.8 (9.9-13); P-value <0.001). Conclusions. Umifenovir may reduce the need for admission to the ICU and mortality rate in patients with COVID-19 compared with lopinavir/ritonavir. The lab test trends were also in favor of umifenovir use.

The global burden of cancer attributable to risk factors, 2010-19 : a systematic analysis for the Global Burden of Disease Study 2019

Background Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings Globally, in 2019, the risk factors included in this analysis accounted for 4.45 million (95% uncertainty interval 4.01-4.94) deaths and 105 million (95.0-116) DALYs for both sexes combined, representing 44.4% (41.3-48.4) of all cancer deaths and 42.0% (39.1-45.6) of all DALYs. There were 2.88 million (2.60-3.18) risk-attributable cancer deaths in males (50.6% [47.8-54.1] of all male cancer deaths) and 1.58 million (1.36-1.84) risk-attributable cancer deaths in females (36.3% [32.5-41.3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20.4% (12.6-28.4) and DALYs by 16.8% (8.8-25.0), with the greatest percentage increase in metabolic risks (34.7% [27.9-42.8] and 33.3% [25.8-42.0]). Interpretation The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

Determination of Voriconazole Plasma Concentration by HPLC Technique and Evaluating Its Association with Clinical Outcome and Adverse Effects in Patients with Invasive Aspergillosis

Purpose. Invasive aspergillosis is a prevalent fungal disease, especially in Asian countries with a high mortality rate. Voriconazole (VRZ) is the first choice for invasive aspergillosis treatment. Plasma concentration of this drug is unpredictable and varies among individuals. This variability is influenced by many factors leading to clinical implication. Therapeutic drug monitoring (TDM) may have a crucial role in the patients’ treatment process. The HPLC method provides sufficient specificity and sensitivity for plasma VRZ concentration determination for TDM purposes of this drug. Methods. Patients who initiated oral or intravenous VRZ for invasive aspergillosis were enrolled in this study. Demographic characteristics and clinical data, outcome, and adverse effects were documented. For each patient, the plasma sample was collected under steady-state condition and analyzed using a validated HPLC method. Results. A total of 22 measurements were performed. Fifty percent of patients were out of the therapeutic range. From them, 27.27% and 22.73% were in subtherapeutic and supratherapeutic ranges (5.5 μg/mL), respectively. There was a significant correlation between VRZ plasma concentration and treatment outcomes (P=0.022). Treatment failure was five times higher than treatment success in those in the subtherapeutic range. Adverse effects were observed more frequently in patients with supratherapeutic concentrations compared to those with non-supratherapeutic levels. Furthermore, the mortality rate in patients experiencing treatment failure was 2.17 times higher than those with treatment success. Conclusions. TDM of VRZ plays an important role in better evaluation of efficacy and toxicity during treatment. Therefore, determination of the drug level may be of clinical significance

A Pregnant Woman with a Diagnosis of COVID-19 without Clinical Manifestations: A Case Report: A Pregnant Woman with a Diagnosis of COVID-19

A 41 year old woman, 38 weeks and 3 days pregnant, without any past medical history and gravida (G) 4, parity (P) 2 and abortion (Ab) 2, gave birth by Cesarean section. The patient did not have any fever, cough, and dyspnea and did not report any close contact with COVID-19 patients. She was extubated post-surgery in the recovery room. She had oxygen saturation (SpO2) of 87-93% with face mask and was transferred to medical ward. Six hours later, she experienced dyspnea and her SpO2 fell down to 83%. Ten hours after surgery, due to worsening of her dyspnea and SpO2 of 78%, cardiology consultation was conducted and patient was admitted to the intensive care unit (ICU) with the diagnosis of pulmonary thromboembolism (PTE). Cardiac consultation and echocardiography excluded PTE. In the ICU, her chest computerized tomography scan (CT-scan) showed bilateral ground glass opacity in favor of COVID-19. Reverse Transcription-Polymerase Chain Reaction (RT-PCR) for COVID-19 was also positive. The baby was born with an Apgar score of 9, a normal physical examination and a positive PCR test for COVID-19

Successful IgM-enriched immunoglobulin treatment in severe COVID-19 pneumonia: a case report

Coronavirus disease (COVID-19) pandemic has turned into one of the most considerable challenges worldwide. The optimal treatment strategy, particularly in severely ill patients, is still unrecognized. IgM-enriched immunoglobulin (Pentaglobin®, Biotest AG, Dreieich, Germany) contains IgM, IgA and IgG against a variety of pathogens representing passive immune protection for affected individuals and it may be effective in the treatment of COVID-19. On March 16, 2020, a 32-year-old woman presented to Masih Daneshvari Hospital, Tehran, Iran. On admission, the peripheral oxygen saturation (O2 Sat) was 84%. Spiral chest computed tomography (CT) scan revealed bilateral ground-glass opacification (GGO) involvement. On March 19, 2020, the clinical condition was deteriorated, and her O2 Sat decreased to 70% in ambient air. Treatment with IgM-enriched immunoglobulin was immediately initiated over the course of three days (total dose for the patient was calculated to be 1500 ml). On the seventh day of hospitalization, the patient was discharged with satisfactory general condition, without any complaints, and with stable vital signs and O2 Sat of 95% on room air. In conclusion, IgM-enriched immunoglobulin could be considered as a potential option for the treatment of severely ill patients with COVID-19
