Efficacy of topical galbanum oil with dry cupping in hospitalized COVID-19 patients: A randomized open-label clinical trial.

Objective: This study was designed to detect the therapeutic effects of galbanum oil plus dry cupping (a Persian medicine-based method) in hospitalized patients with coronavirus disease-2019 (COVID-19). Materials and Methods: In this randomized controlled trial, 60 hospitalized COVID-19 patients with positive polymerase chain reaction test (PCR), pulmonary involvement and blood oxygen saturation (SpO2) ≤93 mmHg, were randomly assigned into two groups to take the standard therapeutic regimen alone or alongside cupping and topical galbanum oil (Ferula gommosa oleo-gum resin) for 3-5 days. The SpO2 level, the severity of signs and symptoms of patients and laboratory parameters were compared between the two groups. Results: Fifty-eight patients were analyzed. The SpO2 level changed from 89.27±3.82 to 90.29±3.09 mmHg (p=0.038) in control group, while it increased from 88.74±3.45 to 94.23±2.1 mmHg (<0.001) in galbanum group with a significant difference between the groups (p<0.001). Fever, cough, dyspnea, and anorexia alleviated in the galbanum group more than the control (p=0.003, 0.001, 0.01, and 0.04, respectively). No adverse effects were reported due to galbanum oil and cupping therapy. Conclusion: Dry cupping with galbanum oil alongside the routine therapeutic regimen could be more effective than the routine therapeutic regimen alone for improving SpO2 level and alleviating fever, cough, and dyspnea in COVID-19 patients.

Comparing efficacy and safety of high-dose and standard-dose rifampicin in the treatment of brucellosis: a randomized clinical trial.

BACKGROUND: In a few studies, higher doses of rifampicin improved the outcome of patients with TB. There is no information regarding efficacy and safety of higher doses of rifampicin in patients with brucellosis. OBJECTIVES: To compare efficacy and safety of higher and standard doses of rifampicin, each with doxycycline, in the treatment of patients with brucellosis. METHODS: Within a randomized clinical trial, clinical response and adverse events of high-dose rifampicin (900-1200 mg/day) plus doxycycline 100 mg twice daily were compared with standard-dose rifampicin (600 mg/day) plus doxycycline 100 mg twice daily in 120 patients with brucellosis. RESULTS: Clinical response occurred in 57 (95%) of patients in the high-dose group and 49 (81.66%) of patients in the standard-dose group (P = 0.04). The most common adverse events of the treatment were nausea (37.5%), skin rash (13.33%), vomiting (10%) and transaminitis (7.22%). Incidence of these events was comparable between the groups. CONCLUSIONS: The rate of clinical response in patients with brucellosis who were treated with high-dose rifampicin plus standard-dose doxycycline was significantly higher than in the patients who received the standard doses of rifampicin and doxycycline, without further adverse events. The high-dose rifampicin therefore improved clinical response in patients with brucellosis with a similar safety profile to the standard dose. If these findings are confirmed in future studies, higher doses of rifampicin may be recommended for treatment of patients with brucellosis.

Efficacy of a multiple-indication antiviral herbal drug (Saliravira®) for COVID-19 outpatients: A pre-clinical and randomized clinical trial study.

BACKGROUND: The scientific researches on COVID-19 pandemic topics are headed to an explosion of scientific literature. Despite these global efforts, the efficient treatment of patients is an in-progress challenge. Based on a meta-study of published shreds of evidence about compounds and their botanic sources in the last six decades, a novel multiple-indication herbal compound (Saliravira®) has been developed. Based on the antiviral, anti-inflammatory, and immune-enhancing properties of its ingredients, we hypothesized that Saliravira® has the potential to act as an antiviral agent, accelerate treatment, and reduce undesirable effects of COVID-19. METHODS: In this randomized, controlled, open-label clinical trial, COVID-19 outpatients were included by RT-PCR test or diagnosis of physicians according to the symptoms. Participants were randomly divided into intervention and control groups to receive Saliravira® package plus routine treatments of COVID-19 or routine treatments of COVID-19 alone, respectively. Saliravira® package includes tablets, nasal-sinuses spray, oral-pharynx spray, and inhaler drops. The treatment was for 10 days and followed up till 23 days after admission. RESULTS: On the 8th day, the "mean reduction rates" of viral load of the patients in the intervention group was 50% lower compared to the control group with a p-value < 0.05. The improvement of 10 out of 14 COVID-19 symptoms in the intervention group was significantly accelerated. The mean treatment duration of patients in the intervention group was 4.9 days less than the control group. In addition, no patients in the intervention group were hospitalized compared to 28% of the control group needed to be hospitalized.

Effect of green tea consumption in treatment of mild to moderate depression in Iranian patients living with HIV: A double-blind randomized clinical trial / 中草药·英文版

Objective: Depression affects people living with HIV (PLWH) compliance leading to poor control infection. Previous observational studies showed an anti-depression effect of green tea extract (GTE). The therapeutic effect of GTE on depression were investigated in PLWH receiving antiretroviral therapy (ART). Methods: Fifty PLWH on ART with diagnose of mild to moderate of depression, participated in a double-blind, placebo-controlled trial and underwent 12 weeks of treatment with either 400 mg GTE capsules or placebo twice daily. The Hamilton depression scale of patients was measured before, 6 weeks and 12 weeks after treatment in two groups. The primary outcome measure was performed to evaluate the efficacy of GTE in improving depressive symptoms. Results: The mean of Hamilton score showed a significant difference between the two groups after 12 weeks (P = 0.035). Repeated measures ANOVA test showed a significant effect for time × treatment interaction on the Hamilton mean score between the two groups (P = 0.000). Conclusion: It seems the use of GTE capsules in PLWH on ART is safe and could lead to greater and more rapid improvement in depressive symptoms than placebo. Thus it can be considered as an alternative therapy for mild to moderate depression. Further studies with higher sample size and longer follow-up and comparisons with other antidepressive drugs are warranted.

Low level of antifungal resistance of Candida glabrata blood isolates in Turkey: Fluconazole minimum inhibitory concentration and FKS mutations can predict therapeutic failure.

BACKGROUND: Candida glabrata is the third leading cause of candidaemia in Turkey; however, the data regarding antifungal resistance mechanisms and genotypic diversity in association with their clinical implication are limited. OBJECTIVES: To assess genotypic diversity, antifungal susceptibility and mechanisms of drug resistance of C glabrata blood isolates and their association with patients' outcome in a retrospective multicentre study. PATIENTS/METHODS: Isolates from 107 patients were identified by ITS sequencing and analysed by multilocus microsatellite typing, antifungal susceptibility testing, and sequencing of PDR1 and FKS1/2 hotspots (HSs). RESULTS: Candida glabrata prevalence in Ege University Hospital was twofold higher in 2014-2019 than in 2005-2014. Six of the analysed isolates had fluconazole MICs ≥ 32 µg/mL; of them, five harboured unique PDR1 mutations. Although echinocandin resistance was not detected, three isolates had mutations in HS1-Fks1 (S629T, n = 1) and HS1-Fks2 (S663P, n = 2); one of the latter was also fluconazole-resistant. All patients infected with isolates carrying HS-FKS mutations and/or demonstrating fluconazole MIC ≥ 32 µg/mL (except one without clinical data) showed therapeutic failure (TF) with echinocandin and fluconazole; seven such isolates were collected in Ege (n = 4) and Gulhane (n = 3) hospitals and six detected recently. Among 34 identified genotypes, none were associated with mortality or enriched for fluconazole-resistant isolates. CONCLUSION: Antifungal susceptibility testing should be supplemented with HS-FKS sequencing to predict TF for echinocandins, whereas fluconazole MIC ≥ 32 µg/mL may predict TF. Recent emergence of C glabrata isolates associated with antifungal TF warrants future comprehensive prospective studies in Turkey.

Molecular Identification, Genotypic Diversity, Antifungal Susceptibility, and Clinical Outcomes of Infections Caused by Clinically Underrated Yeasts, Candida orthopsilosis, and Candida metapsilosis: An Iranian Multicenter Study (2014-2019).

Despite the increasing occurrence of Candida orthopsilosis and Candida metapsilosis in clinical settings, little is known about their microbiological and clinical properties. Herein, we conducted a national retrospective study (2014-2019) from multiple centers in Iran. Among the 1,770 Candida isolates collected, we identified 600 Candida parapsilosis species complex isolates. Isolate identification was performed by 9-plex PCR, matrix-assisted laser desorption-time of flight mass spectrometry (MALDI-TOF MS), and rDNA sequencing, and antifungal susceptibility testing (AFST) followed CLSI M27-A3/S4; genotyping was performed by amplified fragment length polymorphism (AFLP) analysis; and clinical information was mined. Thirty-one isolates of C. orthopsilosis from various clinical sources, one mixed sample (blood) concurrently containing C. orthopsilosis and C. parapsilosis and one isolate of C. metapsilosis from a nail sample were identified. Although both 9-plex PCR and MALDI-TOF successfully identified all isolates, only 9-plex PCR could identify the agents in a mixed sample. For the C. orthopsilosis isolates, resistance (non-wild type) was noted only for itraconazole (n = 4; 12.5%). Anidulafungin and fluconazole showed the highest and voriconazole had the lowest geometric mean values. AFLP analysis showed three main and four minor genotypes. Interestingly, 90% of nail isolates clustered with 80% of the blood isolates within two clusters, and four blood isolates recovered from four patients admitted to a hospital clustered into two genotypes and showed a high degree of similarity (>99.2%), which suggests that C. orthopsilosis disseminates horizontally. Supported by our data and published case studies, C. orthopsilosis and C. metapsilosis can be linked to challenging clinical failures, and successful outcomes are not always mirrored by in vitro susceptibility. Accordingly, conducting nationwide studies may provide more comprehensive data, which is required for a better prognosis and clinical management of patients.
