Background: The effect of midodrine on lactate clearance has not been assessed in critically ill patients yet. Objective: The goal of this study was to assess the effect of adjunctive midodrine therapy on lactate clearance in patients with septic shock. Materials & methods: Patients with septic shock were assigned to receive either adjunctive midodrine 10 mg three-times a day for 5 days (midodrine group = 15 patients) or not (control group = 13 patients). Results: The lactate clearance was significantly faster in the midodrine group than the control group (p = 0.049) with a large effect size (ηp2 = 0.141). Conclusion: When midodrine was added to intravenous vasopressors, it significantly accelerated lactate clearance in patients with septic shock. Trial registration number: IRCT20100228003449N25 (

In this study, efficacy and safety of interferon (IFN) ß-1b in the treatment of patients with severe COVID-19 were evaluated. Among an open-label, randomized clinical trial, adult patients (≥18 years old) with severe COVID-19 were randomly assigned (1:1) to the IFN group or the control group. Patients in the IFN group received IFN ß-1b (250 mcg subcutaneously every other day for two consecutive weeks) along with the national protocol medications while in the control group, patients received only the national protocol medications (lopinavir/ritonavir or atazanavir/ritonavir plus hydroxychloroquine for 7-10 days). The primary outcome of the study was time to clinical improvement. Secondary outcomes were in-hospital complications and 28-daymortality. Between April 20 and May 20, 2020, 80 patients were enrolled and finally 33 patients in each group completed the study. Time to clinical improvment in the IFN group was significantly shorter than the control group ([9(6-10) vs. 11(9-15) days respectively, p = 0.002, HR = 2.30; 95% CI: 1.33-3.39]). At day 14, the percentage of discharged patients was 78.79% and 54.55% in the IFN and control groups respectively (OR = 3.09; 95% CI: 1.05-9.11, p = 0.03). ICU admission rate in the control group was significantly higher than the IFN group (66.66% vs. 42.42%, p = 0.04). The duration of hospitalization and ICU stay were not significantly different between the groups All-cause 28-day mortality was 6.06% and 18.18% in the IFN and control groups respectively (p = 0.12). IFN ß-1b was effective in shortening the time to clinical improvement without serious adverse events in patients with severe COVID-19. Furthermore, admission in ICU and need for invasive mechanical ventilation decreased following administration of IFN ß-1b. Although 28-day mortality was lower in the IFN group, further randomized clinical trials with large sample size are needed for exact estimation of survival benefit of IFN ß-1b.

BACKGROUND: The role of the antiviral therapy in treatment of COVID-19 is still a matter to be investigated. Also efficacy and safety of antiviral regimens were not compared according severity of the disease. In this study the efficacy and safety of hydroxychloroquine plus atazanavir/ritonavir was compared in patients with moderate and severe COVID-19. METHODS: We prospectively evaluated the clinical outcomes of 213 patients with COVID-19 during the hospitalization course and up to 56 days after the hospital discharge. The disease was categorized to moderate and severe based on the severity of pneumonia and peripheral oxygen saturation (SpO2). The patients received the national treatment protocol containing hydroxychloroquine (400 mg BD in first day and then 200 mg BD) plus atazanavir/ritonavir (300/100 mg daily) for 7 days. Main outcomes included discharge rates at day 7, 14 and 28, 28-day mortality, rate of intensive care unit (ICU) admission and intubation, length of hospital and ICU stay and incidence of adverse events. RESULTS: The mean (SD) age of patients was 60(14) years and 53% were male. According to WHO definition, 51.64% and 48.36% of the patients had moderate (SpO2 ≥ 90%) and severe disease (SpO2 < 90%) at baseline, respectively. The discharge rate of the moderate group was significantly higher than the severe group at day 7, 14 and 28 (HR = 0.49; 95% CI: 0.35-0.69, p = < 0.001 at day 7, HR = 0.48; 95% CI: 0.35-0.66, p = < 0.001 at day 14 and HR = 0.49; 95% CI: 0.36-0.67, p = < 0.001at day 28). The 28-day mortality of the severe group was six times higher than the moderate group (HR = 6.00; 95% CI: 2.50-14.44), p = < 0.001). The need of admission in ICU for the severe group and the moderate group was 37.86% and 18.18% of the patients. Length of hospital stay was significantly shorter in the moderate group in comparison with the severe group (5 ± 4 vs. 8 ± 6 days, p < 0.001). Patients in the moderate group experienced the serious adverse events and complications less than the severe group. The discharged patients were followed up to 56 days after discharge. Some of the patients complained of symptoms such as exertional dyspnea, weakness and new-onset hair loss. CONCLUSION: Our study did not support the use of hydroxychloroquine plus atazanavir/ritonavir in patients who had SpO2 < 90% at the time of hospital admission. SpO2 was the only predictor of clinical outcomes (duration of hospital stay, discharge from the hospital and mortality) in patients treated with hydroxychloroquine plus atazanavir/ritonavir.

To the best of our knowledge, there is no published study on the use of interferon ß-1a (IFN ß-1a) in the treatment of severe COVID-19. In this randomized clinical trial, the efficacy and safety of IFN ß-1a were evaluated in patients with severe COVID-19. Forty-two patients in the interferon group received IFN ß-1a in addition to the national protocol medications (hydroxychloroquine plus lopinavir-ritonavir or atazanavir-ritonavir). Each 44-µg/ml (12 million IU/ml) dose of interferon ß-1a was subcutaneously injected three times weekly for two consecutive weeks. The control group consisted of 39 patients who received only the national protocol medications. The primary outcome of the study was time to reach clinical response. Secondary outcomes were duration of hospital stay, length of intensive care unit stay, 28-day mortality, effect of early or late administration of IFN on mortality, adverse effects, and complications during the hospitalization. Between 29 February and 3 April 2020, 92 patients were recruited, and a total of 42 patients in the IFN group and 39 patients in the control group completed the study. As the primary outcome, time to the clinical response was not significantly different between the IFN and the control groups (9.7 ± 5.8 versus 8.3 ± 4.9 days, respectively, P = 0.95). On day 14, 66.7% versus 43.6% of patients in the IFN group and the control group, respectively, were discharged (odds ratio [OR], 2.5; 95% confidence interval [CI], 1.05 to 6.37). The 28-day overall mortality was significantly lower in the IFN than the control group (19% versus 43.6%, respectively, P = 0.015). Early administration significantly reduced mortality (OR, 13.5; 95% CI, 1.5 to 118). Although IFN did not change the time to reach the clinical response, adding it to the national protocol significantly increased discharge rate on day 14 and decreased 28-day mortality. (This study is in the Iranian Registry of Clinical Trials under identifier IRCT20100228003449N28.).

Valproate-induced hyperammonemia is a common side effect of valproate, which may occur either without any symptoms or may rarely cause symptoms of encephalopathy. Different risk factors have been defined for this side effect, including some nutritional deficiencies and polypharmacy (eg, other anticonvulsants). Three cases with psychiatric disorder who showed symptoms of severe hyperammonemia encephalopathy and had taken valproate with antipsychotics, especially risperidone, are presented here. In all cases, the symptoms were improved by discontinuation of valproate. Administration of antipsychotic may be considered as a risk factor for hyperammonemic encephalopathy related to valproate, specifically in some prone populations.

Data on the status of carbapenem-resistant microorganisms in the Middle East countries are scarce. The aim of this review was to collect available data regarding resistance to carbapenems in a Middle East region. Available data regarding carbapenem-resistant isolates were considered for evaluation in this review. Biomedical electronic databases were systematically searched to find related articles. The key terms used were "carbapenem-resistant, resistant gram-negative bacilli, Enterobacteriaceae, fermenting and non-fermenting gram-negative bacilli, Pseudomonas, Acinetobacter, Klebsiella and Iran". After primary screening, 275 relevant articles were selected to be assessed thoroughly. Resistance rate to carbapenems was reported between 1% and 86% during years 2006-2018. Most of the carbapenem-resistant microorganisms were isolated from burn patients. Modified Hodge test was a commonly used phenotypic test. Only in few studies, genotypic assays were considered. Pattern of antibiotic use can affect emergence of resistant microorganisms. Rational use of drugs, and specifically, antibiotics is a challenging issue in developing countries. Mean number of drugs per prescription in these countries was higher than the World Health Organization standards. Overuse of antibiotics, especially injectable ones, and easy access to antibiotics without prescription is a warning alarm for future antibiotic resistance in developing countries. Establishing antimicrobial stewardship's programs is new in the hospitals. Unfortunately, rules and regulatory issues to restrict antibiotic access in community pharmacies and prescription by general physicians are limited.
