Inflawell® improves neutrophil-to-lymphocyte ratio and shortens hospitalization in patients with moderate COVID-19, in a randomized double-blind placebo-controlled clinical trial.

AIMS: COVID-19 is a significant global threat to public health. Despite the availability of vaccines and anti-viral drugs, there is an urgent need for alternative treatments to help prevent and/or manage COVID-19 symptoms and the underlying dysregulated immune response. We hypothesized that administration of Inflawell® syrup, a Boswellia extract formulation enriched for boswellic acids (BAs), can reduce the excessive or persistent inflammation and thereby prevent disease progression. BAs are medicinally activated triterpenoids found in the resins of Boswellia spp., and possess an immense therapeutic potential due to their anti-inflammatory and immunoregulatory activities. We investigated the effect of Inflawell® syrup, on moderate COVID-19 patients along with the current standard of care treatment. METHODS: A randomized placebo-controlled double-blind clinical trial was conducted, following definitive confirmation of COVID-19. Forty-seven hospitalized patients with moderate COVID-19 were enrolled and received either the Inflawell® syrup or placebo. Clinical symptoms and markers of inflammation were evaluated at baseline and completion of the trial. RESULTS: Our clinical trial revealed an increase in the percentage of oxygen saturation level in patients that received the BAs compared to placebo (P < 0.0001). In addition, the average duration of hospitalization was significantly shorter in the BAs group compared with the placebo group (P < 0.04). Concomitantly, some improvement in the clinical symptoms including cough, dyspnea, myalgia, headache, and olfactory and gustatory dysfunction were detected in the BAs group. Hematologic findings showed a significant decrease in the percentage of neutrophils (P < 0.006) and neutrophil-to-lymphocyte ratio (NLR) levels (P < 0.003), associated with a significant increase in the percentage of lymphocytes in the BAs group compared with the placebo (P < 0.002). Additionally, a significant decrease in CRP, LDH, IL - 6 and TNF - α levels was detected in the BAs group. Following the intervention, fewer patients in the BAs group were PCR-positive for COVID-19 compared to placebo, though not statistically significant. CONCLUSION: Overall, the treatment with Inflawell® resulted in shorter hospital stay, alleviation of COVID-19 clinical symptoms and decline in the level of pro-inflammatory cytokines.

An investigation into the Effects of Intravenous Vitamin C on Pulmonary CT Findings and Clinical Outcomes of Patients with COVID 19 Pneumonia A Randomized Clinical Trial.

PURPOSE: In late December 2019, a series of unexplained cases of pneumonia were reported in Wuhan, China. On January 12, 2020, the World Health Organization temporarily named the virus responsible for the emerging cases of pneumonia as the 2019 coronavirus. Acute respiratory distress syndrome (ARDS) due to Covid-19 has rapidly spread around the world, and while no specific treatment or vaccine has been reported, mortality rates remain high. One of the suggested treatments for cellular damage in the pathogenesis of ARDS caused by the coronavirus is the administration of high doses of intravenous vitamin C. Considering the paucity of literature on the therapeutic effects of high doses of intravenous vitamin C in patients with ARDS resulting from the coronavirus, this study was conducted to assess this therapeutic supplement in these patients. MATERIALS AND METHODS: This study was performed as a single-center clinical trial in patients with a documented diagnosis of COVID-19 pneumonia. 54 eligible patients with moderate to severe COVID-19 symptoms, based on specific inclusion and exclusion criteria, were included in the investigation and randomly divided into two groups. The control group consisted of 26 patients who received standard treatment, whereas the treatment group was comprised of 18 patients administered intravenous vitamin C at a dose of 2 g every 6 hours for 5 days in addition to standard treatment. Demographic characteristics, underlying diseases, length of hospital stay, and mortality rates were reviewed and collected. Oxygen saturation, respiratory rates, serum C Reactive Protein (CRP) levels, lymphopenia and lung parenchymal involvement on CT were investigated at the time of admission and on the sixth day after hospitalization. Finally, all variables were analyzed with IBM SPSS Statistics 23 software and a significant statistical difference was defined for all variables, P <0.05. RESULTS: Of these variables, the amount of oxygen saturation in the vitamin C group increased significantly from 86±5% on the first day of hospitalization to 90±3% on the sixth day of hospitalization (P value=0.02). Also, the respiratory rate in the vitamin C group decreased significantly from 27±3 on the first day of hospitalization to 24±3 on the sixth day of hospitalization (P value=0.03). Lung CT scans of patients in the two groups reported by two radiologists were also compared. Based on the report of the radiologists, the rate of lung involvement in the vitamin C group was significantly lower than in the control group at the end of treatment (P value=0.02). CONCLUSION: Due to the effectiveness of high doses of intravenous vitamin C on reducing lung involvement and improving clinical symptoms, further studies with a larger sample size are recommended to demonstrate the effects of this drug supplement.

COVID-19 reinfection or reactivation in a renal transplant patient.

Recurrences of COVID-19 infection may occur in immunocompromised patients. Reinfection or reactivation of COVID-19 virus is a challenging issue in these patients.

Fatal invasive pulmonary aspergillosis in an immunocompetent patient with COVID-19 due to Aspergillus terreus: A case study.

Case reports of CAPA emerged. In most of the reports, the predominant species is Aspergillus fumigatus. Uncommon species are less reported. Due to poor clinical outcome with Aspergillus terreus, the increasing reports with this agent require attention.

COVID-19 and kidney transplant recipients.

BACKGROUND: The novel coronavirus has become a global threat and healthcare concern. The manifestations of COVID-19 pneumonia in transplant patients are not well understood and may have more severe symptoms, longer duration, and a worse prognosis than in immunocompetent populations. AIMS: This study proposed to evaluate the clinical characteristics of COVID-19 pneumonia in kidney transplant recipients. PATIENTS/METHODS: Clinical records, laboratory results, radiological characteristics, and clinical outcome of 24 kidney transplant patients with COVID-19 pneumonia were evaluated from March 20, 2020, to May 20, 2020. RESULTS: The most common symptom was shortness of breath (70.8%), followed by fever (62.5%) and cough (45.8%). Five patients had leukopenia, and only one patient had leukocytosis, while 75% of the patients had a white blood cell (WBC) count in the normal range, and 79% of recipients developed lymphopenia. All of the patients had an elevated concentration of C-reactive protein and an increase in blood urea levels. Chest CT images of 23 patients (95.8%) showed typical findings of patchy ground-glass shadows in the lungs. Of the 24 patients, 12 were admitted to ICU (invasive care unit), and ten of 24 patients (41.6%) died, and 14 patients were discharged after complete recovery. CONCLUSION: It seems that COVID-19 is more severe in transplant patients and has poorer outcomes. Multiple underlying diseases, low O2 saturation, and multilobar view in chest CT scan may be of prognostic value. However, many SARS-CoV-2 demonstrations are similar to those of the general population.
