ABSTRACT
BACKGROUND: Regarding the COVID-19 pandemic, potential therapeutic agents are being evaluated almost every day. Ciclosporin, a calcineurin inhibitor, is characterized by beneficial antiviral and immunomodulatory effects. The present study aimed to evaluate the efficacy of ciclosporin in managing COVID-19. METHODS: This study was a prospective non-controlled clinical trial carried out on 20 patients. Confirmed COVID-19 patients received two doses of ciclosporin (10 mg/kg and 5 mg/kg injections) 24 h apart. Mortality rate and the lengths of intensive care unit (ICU) and hospital stays were assessed for all 20 patients. RESULTS: The mortality rate and the need for mechanical ventilation were calculated as 50%. The percentage of ICU admission was 70%. The lengths of ICU and hospital stays were 8.13 ± 6.81 and 14.25 ± 8.55 days, respectively. The levels of ferritin and white blood cells were significantly higher after injecting the second dose of ciclosporin. Seven patients (35%) had radiologically improved lungs after ciclosporin therapy. CONCLUSION: It seems that the protocol of two doses of ciclosporin in combination with favipiravir does not have favorable effects among COVID-19 patients that do not respond to dexamethasone. Controlled trials are needed to confirm the results.

Interferon Beta-1a (IFN-ß1-a), an immunomodulatory mediator with antiviral effects, has shown in vivo and in vitro activities especially on coronavirus including SARS-CoV-2. COVID-19 defined as the disease caused by infection with SARS-CoV-2. The virus has been illustrated inhibits the production of IFN-ß1-a from inflammatory cells. We conducted a retrospective study of all adult confirmed COVID-19 hospitalized patients who received combination of three doses of 12 million international units of IFN-ß1-a and Lopinavir 400 mg and Ritonavir 100 mg every 12 h (case group) for 14 days besides standard care and age- and sex- matched COVID-19 patients with receiving lopinavir/ritonavir (control group) at Masih Daneshvari Hospital as a designated hospital for COVID-19 between Feb 19 and Apr 30, 2020. Multivariate analysis was done to determine the impact of IFN-ß1-a on outcome and all-cause mortality. 152 cases in IFN-ß1-a group and 304 cases as control group were included. IFN-ß1-a group stayed at hospital longer and required noninvasive ventilation more than control group (13 vs. 6 days, p = 0.001) and (34% vs. 24%, p = 0.04), respectively. During treatment, 57 (12.5%) patients died. The death rate in case and control groups was 11% and 13% respectively. In multivariate analysis, not receiving IFN-ß1-a (HR 5.12, 95% CI: 2.77-9.45), comorbidity (HR 2.28, 95% CI: 1.13-4.60) and noninvasive ventilation (HR 2.77, 95% CI: 1.56-4.93) remained significantly associated with all-cause mortality. In this study, risk of death decreased by using IFN-ß1-a in COVID-19 patients. More clinical study will be necessary to measure efficacy of IFN-ß1-a in COVID-19 treatment.

Objective. This study aimed to report the molecular detection and antimicrobial resistance of Aeromonas among houseflies (Musca domestica) in Shahrekord and Isfahan provinces of Iran. Materials and methods. Flies were caught from household kitchens, cattle farms, animal hospitals, human hospitals, slaughter house and poultry farms and put in collection separate sterile tubes. Isolation was accomplished by culture of flies in alkaline peptone water followed by identification with Aeromonas-specific Polymerase Chain Reaction (PCR). Results. Out of 600 houseflies 73 (12.2%) were infected with Aeromonas spp. Significantly higher frequencies of Aeromonas were isolated in Shahrekord province (13.0%; 39/300) than in Isfahan province (11.3%; 34/300). The recovery frequencies of the organisms were significantly lower in kitchens as compared to those in cattle farms and hospital wards which were similar. Higher proportions of infected flies were obtained during summer whereas low proportions were obtained during winter. Conclusions. It is concluded that houseflies do harbor diarrheagenic pathogens, including Aeromonas especially during summer. The carried organisms are resistant to a number of antimicrobials at different levels. Thus, future plans aimed at stemming infections caused by these organisms should take flies into account. Control efforts of infections caused by this particular bacterium should therefore take into account Musca domestica.
Objetivo. Este estudio tuvo como objetivo informar de la detección molecular y resistencia antimicrobiana de Aeromonas entre moscas domésticas (Musca domestica) en las provincias de Shahrekord y Isfahan de Irán. Materiales y métodos. Las moscas fueron capturadas en las cocinas domésticas, granjas de ganado, hospitales de animales, hospitales humanos, mataderos y granjas avícolas y pusieron en tubos separados estériles de recolección. El aislamiento se llevó a cabo por cultivo de moscas en agua de peptona alcalina seguida por la identificación con la reacción en cadena de polimerasa Aeromonas-específica (PCR). Resultados. De 600 moscas domésticas 73 (12.2%) estaban infectadas con Aeromonas spp. Se aislaron significativamente mayores frecuencias de Aeromonas en la provincia Shahrekord (13.0%; 39/300) que en la provincia de Isfahan (11.3%; 34/300). Las frecuencias de recuperación de los organismos fueron significativamente más bajos en las cocinas, en comparación con las granjas de ganado y salas de hospitales que fueron similares. Mayores proporciones de moscas infectadas se obtuvieron durante el verano mientras que bajas proporciones se obtuvieron durante el invierno. Conclusiones. Se concluye que las moscas domésticas no albergan patógenos diarreogénicos, incluyendo Aeromonas especialmente durante el verano. Los organismos llevadas a son resistentes a un número de antimicrobianos en diferentes niveles. Este modo, los planes futuros dirigidos a limitar las infecciones causadas por estos organismos deberían tomar en cuenta las moscas. Los esfuerzos de control de infecciones causadas por esta bacteria en particular, por lo tanto debería tener en cuenta Musca doméstica.
