RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Zataria multiflora is employed as an antitussive, anti-spasmodic, analgesic and etc. Agent in traditional medicine. The modern medical studies are also confirmed effects of this plant for treatment of respiratory problems via anti-inflammatory, anti-oxidant and immunomodulatory properties. AIM OF STUDY: We evaluated efficacy of Z. multiflora on tests of pulmonary function, respiratory symptoms, inhaled bronchodilator drugs use, and hematological factors in COPD patients. METHODS: Patients (n = 45) were randomly grouped in the following three groups: placebo group (P), groups received Z. multiflora extract 3 and 6 mg/kg/day (Z3 and Z6). FEV1 and MEF25-75, respiratory symptoms, inhaled bronchodilator drugs use and hematological factors were evaluated before and 1-2 months after treatment. RESULTS: Z. multiflora led to significant enhancement of FEV1 (p < 0.05 to p < 0.01). Respiratory symptoms were also considerably ameliorated following treatment with extracts for 1 and 2 months compared to baseline values (p < 0.05 to p < 0.001). In groups received extract, inhaled bronchodilator drugs use was remarkably declined at the end of study (both, p < 0.05). Reduction of total WBC was observed 1-2 months after treatment in treated groups with extract compared to baseline values (p < 0.05 to p < 0.001). Neutrophils were remarkably declined in Z3 and Z6 groups after 2-monthes compared to 1-month treatment (p < 0.05 to p < 0.01). CONCLUSION: The evidence show therapeutic effect of this herb on COPD patients which could be result from properties that help to decrease inflammation.

RESUMO

ABSTRACT Background: There is no pharmacological intervention on the treatment of hypoxemia and respiratory distress in COVID-19 patients. Objective: The objective of the study was to study the effect of the reduced form of methylene blue (MB) on the improvement of oxygen saturation (SpO2) and respiratory rate (RR). Methods: In an academic medical center, 80 hospitalized patients with severe COVID-19 were randomly assigned to receive either oral MB along with standard of care (SOC) (MB group, n = 40) or SOC only (SOC group, n=40). The primary outcomes were SpO2 and RR on the 3rd and 5th days. The secondary outcomes were hospital stay and mortality within 28 days. Results: In the MB group, a significant improvement in SpO2 and RR was observed on the 3rd day (for both, p < 0.0001) and also the 5th day (for both, p < 0.0001). In the SOC group, there was no significant improvement in SpO2 (p = 0.24) and RR (p = 0.20) on the 3rd day, although there was a significant improvement of SpO2 (p = 0.002) and RR (p = 0.01) on the 5th day. In the MB group in comparison to the SOC group, the rate ratio of increased SpO2 was 13.5 and 2.1 times on the 3rd and 5th days, respectively. In the MB group compared with the SOC group, the rate ratio of RR improvement was 10.1 and 3.7 times on the 3rd and 5th days, respectively. The hospital stay was significantly shortened in the MB group (p = 0.004), and the mortality was 12.5% and 22.5% in the MB and SOC groups, respectively. Conclusions: The addition of MB to the treatment protocols significantly improved SpO2 and respiratory distress in COVID-19 patients, which resulted in decreased hospital stay and mortality.
