RESUMO
BACKGROUND: Older adults experience persistent symptoms post-COVID-19, termed as Long COVID, affecting their physical and mental health. This study aimed to evaluate the effects of Long COVID, level of physical activity, and functional decline on older adults' health-related quality of life post-COVID-19. METHODS: This cross-sectional study was conducted on 121 older adults with 60 to 90 years old post-coronavirus infection. The standardized metrics used in the study were Fatigue Severity Scale, Physical Activity Elderly, SF12, Post-COVID-19 functional status scale, and COVID-19 Yorkshire rehabilitation screening scale. The severity of coronavirus infection was evaluated by changes in chest CT scan images and O2 saturation at hospital admission. Data were analyzed using linear regression analyses. RESULTS: The results of regression analysis revealed six factors to be predictors of physical health at 6 months post-COVID-19 (F = 9.046, P < 0.001; explained variance 63%), which the significant factors were fatigue, level of physical activity, worsened pain, difficulties in activities of daily living and cognitive-communication problems. Among these factors, greater fatigue and worsened pain intensity were the strongest predictors. Mental health was associated with days of hospitalization and cognitive-communication problems (F = 2.866, P < 0.001; explained variance 35%). CONCLUSIONS: Considering the negative impact of fatigue, pain, low physical activity, and cognitive-communication problems on health-related quality of life, early and accurate evaluation and management are required for recovered older adults post-COVID-19.

Background: According to the World Health Organization, COVID-19 management focuses primarily on infection prevention, case management, case monitoring, and supportive care. However, due to the lack of evidence, no specific anti-SARS-CoV-2 treatment is recommended. This study aimed to evaluate the effectiveness of plasmapheresis treatment in COVID-19 patients with symptoms of pulmonary involvement on the computed tomography (CT) of the lung. Methods: In 2021, an experimental study in critically ill patients admitted to the COVID-19 ward in the Hazrat-e Rasool hospital diagnosed with COVID-19 was conducted in the second phase (pilot study). The diagnosis was confirmed according to clinical signs, CT scan of the lung, and the Polymerase chain reaction (PCR) test. All patients received the usual treatments for COVID-19 disease and underwent plasmapheresis at a dose of 40 cc/kg daily up to 4 doses. All patients were observed for 24 hours for complications of plasmapheresis treatment and simultaneously for symptoms of COVID-19, after which only routine care measures were performed. The next day and 2 weeks after resumption of the treatment, patients experienced COVID-19 symptoms, including shortness of breath, cough, and fever. Blood oxygen saturation, and treatment results were evaluated. Qualitative and rank variables were described using absolute and relative frequencies and quantitative parametric variables were used using mean and confidence interval. Frequencies were compared in groups using the chi-square test. All tests were performed in 2 directions and P > 0.05 was considered statistically significant. Results: Of the 120 patients studied, 79 (65.8%) were men and 41 (34.2%) were women. The mean age was 60.30 ± 15.61 years (22-95 years). The mean hospital stay was 12.89 days ± 7.25 days (2-38 days). Increased blood oxygen saturation levels in patients had an increasing trend. Inflammatory indices had a downward trend in patients. The frequency of plasmapheresis had no significant effect on reducing the downward trend of inflammatory markers. The greatest reduction occurred in the first plasmapheresis. Conclusion: Finally, according to the findings, plasmapheresis is one of the appropriate treatments to improve patients' symptoms and reduce cytokine storm. Recovered patients had lower levels of inflammatory markers than those who died.
RESUMO
The purpose of this study was to compare the effectiveness of Atazanavir/Ritonavir/Dolutegravir/Hydroxychloroquine and Lopinavir/Ritonavir/Hydroxychloroquine treatment regimens in COVID-19 patients based on clinical and laboratory parameters. We prospectively evaluated the clinical and laboratory outcomes of 62 moderate to severe COVID-19 patients during a 10-day treatment plan. Patients were randomly assigned to either KH (receiving Lopinavir/Ritonavir [Kaletra] plus Hydroxychloroquine) or ADH (receiving Atazanavir/Ritonavir, Dolutegravir, and Hydroxychloroquine) groups. During this period, clinical and laboratory parameters and outcomes such as intensive care unit (ICU) admission or mortality rate were recorded. Compared to the KH group, after the treatment period, patients in the ADH group had higher activated partial thromboplastin time (aPTT) (12, [95% confidence interval [CI]: 6.97, 17.06), p = <0.01), international normalized ratio (INR) (0.17, [95% CI: 0.07, 0.27), p = <0.01) and lower C-reactive protein (CRP) (-14.29, (95% CI: -26.87, -1.71), p = 0.03) and potassium (-0.53, (95% CI: -1.03, -0.03), p = 0.04) values. Moreover, a higher number of patients in the KH group needed invasive ventilation (6 (20%) vs. 1 (3.1%), p = 0.05) and antibiotic administration (27 (90%) vs. 21(65.6), p = 0.02) during hospitalization while patients in the ADH group needed more corticosteroid administration (9 (28.1%) vs. 2 (6.7%), p = 0.03). There was no difference in mortality rate, ICU admission rate, and hospitalization period between the study groups. Our results suggest that the Atazanavir/Dolutegravir treatment regimen may result in a less severe disease course compared to the Lopinavir/Ritonavir treatment regimen and can be considered as an alternative treatment option beside standard care. However, to confirm our results, larger-scale studies are recommended.

Background: The COVID-19 infection is a novel virus that mainly targets the respiratory system via specific receptors without any coronavirus-targeted therapies. Many efforts have been made to prepare specific vaccines for COVID-19 or use of prefabricated vaccines of other similar viruses, especially severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and influenza (flu). We aimed to evaluate the effects of previous flu vaccine injection on severity of incoming COVID-19 infection. Methods: We conducted a large cross-sectional study of 529 hospitalized Iranian COVID patients to evaluate the severity of disease courses in patients with or without previous flu vaccination history using some main factors like length of hospitalization, need for the intensive care unit (ICU) admission and length of stay in the ICU for comparison between COVID-19 infected patients with or without flu vaccination history. For the quantitative data, we used independent-samples t and Mann-Whitney tests. The qualitative data were calculated using the Fisher exact and chi-square tests in IBM SPSS Statistics version 22 (SPSS Inc) and P value <0.05 was considered statistically significant. Results: There were no significant differences in the demographic data of patients, disease, and severity-related parameters between the 2 groups. It means that there were not any significant differences between patients with and without history of flu vaccination regarding mean days of hospitalization, percentage of needing to be admitted to the ICU, days being admitted to the ICU (8.44±6.36 vs 7.94±8.57; 17% vs 11.5%; and 1.17±3.09 vs 0.92±3.04, retrospectively) (p=0.883, 0.235, and 0.809, respectively). In the laboratory tests, in comparison between patients with and without history of previous flu vaccination, only lymphocytes count in the vaccine positive group was higher than the vaccine negative group (20.82±11.23 vs 18.04±9.71) (p=0.067) and creatine phosphokinase (CPK) levels were higher in the vaccine negative group (146.57±109.72 vs 214.15±332.06) (p=0.006). Conclusion: We did not find any association between flu vaccination and decrease in disease severity in our patients. It seems that patients with previous history of flu vaccination may experience less laboratory abnormalities in some parameters that could be interpreted in favor of lower overall inflammation; however, this study cannot answer this definitely because of its design. As we collected retrospective data from only alive discharged patients and had no healthy control group, we could not discuss the probable effect of the vaccine on the mortality rate or its probable protective role against the infection. We need more well-designed controlled studies with different populations in different geographic areas to address the controversies.
RESUMO
BACKGROUND: Treatment of patients with COVID-19 has included supportive care to mainly relief symptoms of the disease. Although World Health Organization (WHO) has not recommended any effective treatments for COVID-19, there are some reports about use of antiviral drugs. The aim of this study is to determine the effect of Arbidol (ARB) on COVID-19 disease. METHODS: Using an open-label randomized controlled trial, we examined the efficacy of ARB in patients with COVID-19 in a teaching hospital. One hundred eligible patients with diagnosis of COVID-19 were recruited in the study and assigned randomly to two groups of either hydroxychloroquine followed by KALETRA (Lopinavir/ritonavir) or hydroxychloroquine followed by ARB. The primary outcome was hospitalization duration and clinical improvement 7 days after admission. The criteria of improvement were relief of cough, dyspnea, and fever. Time to relief from fever was also assessed across the two groups. Without any dropouts, 100 patients were entered into the study for the final analysis at significance level of 0.05. RESULTS: The mean age of patients was 56.6 (17.8) years and 56.2 (14.8) years in ARB and KALETRA groups, respectively. Majority of patients were male across two groups (66 and 54%). The duration of hospitalization in ARB group was significantly less than KALETRA arm (7.2 versus 9.6 days; P = 0.02). Time to relief fever was almost similar across two groups (2.7 versus 3.1 days in ARB and KALETRA arms, respectively). Peripheral oxygen saturation rate was significantly different after 7 days of admission across two groups (94% versus 92% in ARB and KALETRA groups respectively) (P = 0.02). Based on multiple linear regression analysis, IHD, Na level, and oxygen saturation at the time of admission and type of therapy were the independent adjusted variables that determined the duration of hospitalization in patients with COVID-19. CONCLUSION: Our findings showed that Arbidol, compared to KALETRA, significantly contributes to clinical and laboratory improvements, including peripheral oxygen saturation, requiring ICU admissions, duration of hospitalization, chest CT involvements, WBC, and ESR. We suggest further studies on ARB against COVID-19 using larger sample size and multicenter design. TRIAL REGISTRATION: IRCT20180725040596N2 on 18 April 2020.

OBJECTIVES: The present study aimed to assess the features, clinical characteristics, and species diversity among patients admitted to referral Hospitals for SARS-CoV-2 pneumonia and mucormycosis in Tehran, Iran, and the relationship between seasonal and species diversity was considered. METHODS: Confirmed COVID-19 patients with a positive reverse-transcriptase real-time (rRT-PCR) test for SARS-CoV2 were primarily included based on clinically suspected mucormycosis infection and confirmed by histopathology and mycology examination of biopsy specimens. The PCR technique was performed by the amplification of the high-affinity iron permease 1 (FTR1) gene for identification and discrimination between Rhizopus arrhizus and non- Rhizopus arrhizus isolates. In contrast, species identification of non-Rhizopus arrhizus was performed by sequencing of ITS rDNA region. RESULTS: Rhino-sino-orbital mucormycosis was identified in the majority of cases (n = 33), with 66 % and 34 % of the cases involving male and female patients, respectively. Rhizopus arrhizus was found to be the most prevalent (84.6 %), followed by Mucor circinelloides (7.6 %). Rhizopus arrhizus was the most prevalent species and present in all the seasons; however, Mucor circinelloides was only present in the autumn. The overall mortality of the total population was 24.6 % (16/ 65); the mortality rates occurring in patients diagnosed with rhino-sino-orbital infection and rhino-sinusal form were 21.4 % and 25 %, respectively. CONCLUSION: CAM can be a serious complication of severe COVID-19, especially in patients with uncontrolled diabetes. It is important to monitor the epidemiology of mucormycosis to raise awareness of the disease and improve diagnosis, treatment and prognosis, particularly in the setting of pandemic.

Background and Purpose: This review aimed to compare the efficacy of acidifying agents and clotrimazole in the treatment of patients with otomycosis. Materials and Methods: The databases, including Research Gate, Google Scholar, ScienceDirect, Embase, Medline, Scopus, Cochrane, and library databases of clinical trials were searched in this study. The keywords were "Fungal Ear Infection" and "Otitis External" for otomycosis, "Clotrimazole", Lotrimin", "Mycelex", "Desenex", and "Clotrimaderm Mycoderm" for clotrimazole, and "Boric Acid Alcohol", "Alcohol-vinegar solution", Burow solution (Domeboro), "Isopropyl Alcohol", "VoSol" and "Acetic Acid" for acidifying agents. Regarding search strategy, a total of 53 studies were collected, 11 of which were maintained for assessment. Almost all studies were published after 1990. These articles discussed the role of clotrimazole and acidifying compounds in the treatment of otomycosis. Moreover, the route of administration, dosage, and side effects of these medications were highlighted. Results: Eight studies had similar results and claimed that clotrimazole has the best or most significant effect on the treatment of otomycosis for patients suffering from pain, itching, swelling, and hearing loss. Conclusion: Although all medications appear effective, there is a paucity of evidence to fully support the decision to choose between clotrimazole or acidifying agents for the treatment of otomycosis in terms of both efficacy and safety. However, in the biomedical field, the re-emerging investigation attention is due to the statements of a number of mechanisms defending the use of acidifying agents to treat mycosis (of antifungal-resistant species).
RESUMO
BACKGROUND: Bacterial and fungal superinfections are commonly reported in patients with coronavirus disease 2019. CASE PRESENTATION: We report the first case of brain and intramedullary abscesses caused by Pseudomonas aeruginosa and a rare case of brain abscesses caused by Aspergillus fumigatus in two post-coronavirus disease 2019 patients. The first patient-34-year-old Iranian woman-presented with weakness of the left upper limb, headaches, and lower limb paresthesia. She had a history of undiagnosed diabetes and had received corticosteroid therapy. The second patient-45-year-old Iranian man-presented with right-sided weakness and had a history of intensive care unit admission. Both patients passed away despite appropriate medical therapy. CONCLUSION: The immune dysregulation induced by coronavirus disease 2019 and its' treatments can predispose patients, especially immunosuppressed ones, to bacterial and fungal infections with unusual and opportunistic pathogens in the central nervous system. Pseudomonas aeruginosa and Aspergillus fumigatus should be considered as potential causes of brain infection in any coronavirus disease 2019 patient presenting with neurological symptoms and evidence of brain abscess in imaging, regardless of sinonasal involvement. These patients should get started on appropriate antimicrobial therapy as soon as possible, as any delay in diagnosis or treatment can be associated with adverse outcomes.

BACKGROUND: As an emerging pandemic disease, COVID-19 encompasses a spectrum of clinical diagnoses, from the common cold to severe respiratory syndrome. Considering the shreds of evidence demonstrating the relationship between human leukocyte antigen (HLA) allele diversity and infectious disease susceptibility, this study was conducted to determine the association of HLA alleles with COVID-19 severity in Iranian subjects. METHODS: In this case-control study, a total of 200 unrelated individuals (consisting of 100 people with severe COVID-19 and an average age of 55.54 as the case group, and 100 patients with mild COVID-19 with an average age of 48.97 as the control group) were recruited, and HLA typing (Locus A, B, and DR) was performed using the Olerup sequence-specific oligonucleotide (SSO) HLA-typing kit. RESULTS: Our results showed that HLA-A*11 and HLA-DRB1*14 alleles were more frequently observed in severe COVID-19 cases, while HLA-B*52 was more common in mild cases, which was in agreement with some previous studies. CONCLUSION: Our results confirmed the evidence for the association of HLA alleles with COVID-19 outcomes. We found that HLA-A*11 and HLA-DRB1*14 alleles may be susceptibility factors for severe COVID-19, while HLA-B*52 may be a protective factor. These findings provide new insight into the pathogenesis of COVID-19 and help patient management.

BACKGROUND: Aspergillus spp. are among the fungal pathogens that can cause life-threatening infections in patients with a history of COVID-19. CASE PRESENTATION: We present the case of a 58-year-old Iranian woman with post-COVID-19 Aspergillus fumigatus endocarditis complicated by numerous thromboembolisms. She underwent mitral valve replacement surgery and multiple lower extremity embolectomies and was treated with voriconazole, which led to her final recovery. CONCLUSIONS: Aspergillus endocarditis should be considered in any patient with suspected endocarditis who has a history of COVID-19 infection and does not respond to routine antibiotic and antifungal therapy, as COVID-19 interferes with proper immune function, and lack of underlying cardiac conditions and immunodeficiencies does not preclude the diagnosis. Culture and histopathological evaluation of vegetations and emboli, as well as PCR, can confirm the diagnosis. Early initiation of antifungal therapy and surgical removal of infected valves and emboli can improve prognosis in patients with Aspergillus endocarditis.

Background and Objectives: Fusarium species are known to be one of the common causes of keratitis. This study was conducted to identify Fusarium spp. causing keratitis and to investigate their genetic diversity using TEF1 and RPB2 gene sequences. Materials and Methods: Twenty-four clinical isolates of Fusarium were isolated from the patient with keratitis. Phylogenetic analysis of two-locus of the 24 clinical isolates and three reference strains was carried out using the maximum parsimony and RAxML methods. Results: Based on gene sequences of the 24 clinical isolates, 17, 4, and 3 isolates were identified as Fusarium solani species complex (FSSC), Fusarium fujikuroi species complex (FFSC), and Fusarium oxysporum, respectively. FFSC include F. proliferatum (n=1), F. globosum (n=1), F. verticillioides (n=1), and F. brevicatenulatum (n=1), respectively. Conclusion: Given that sequence of a sole gene can be challenging and on the other hand, due to the high resistance to antifungal drugs, identification of Fusarium species is of substantial significance. In this study, by designing a novel set of primers for the RPB2 area and using TEF1 primer, we were able to differentiate 24 Fusarium spp. isolated from patients with keratitis.
RESUMO
Here, we report six cases of spontaneous pneumothorax and pneumomediastinitis in patients with COVID-19 in Iran, which were treated with different drugs such as hydroxychloroquine, sofosbuvir, atazanavir, and remdesivir as antiviral agents. Despite the differences in the type of drugs, pneumothorax occurred in all patients.
RESUMO
To our knowledge, no previous studies have reported lung abscess as a complication of COVID-19 infection. It is essential to follow-up with the patients after discharge for such complications, especially if they are symptomatic.
RESUMO
INTRODUCTION AND AIMS: The present study was conducted to determine the candidate genes involved in caspofungin (CAS) resistance in clinical isolates of Aspergillus flavus (A. flavus). MATERIALS AND METHODS: The antifungal susceptibility assay of the CAS was performed on 14 clinical isolates of A. flavus using the CLSI-M-38-A2 broth micro-dilution protocol. Since CAS had various potencies, the minimum effective concentration (MEC) of anidulafungin (AND) was also evaluated in the present study. The FKS1 gene sequencing was conducted to assess whether mutations occurred in the whole FKS1 gene as well as hot spot regions of the FKS1 gene of the two resistant isolates. A complementary DNA-amplified fragment length polymorphism (CDNA-AFLP) method was performed to investigate differential gene expression between the two resistant and two sensitive clinical isolates in the presence of CAS. Furthermore, quantitative real-time PCR (QRT-PCR) was utilized to determine the relative expression levels of the identified genes. RESULTS: No mutations were observed in the whole FKS1 gene hot spot regions of the FKS1 genes in the resistant isolates. A subset of two genes with known biological functions and four genes with unknown biological functions were identified in the CAS-resistant isolates using the CDNA-AFLP. The QRT-PCR revealed the down-regulation of the P-type ATPase and ubiquinone biosynthesis methyltransferase COQ5 in the CAS-resistant isolates, compared to the susceptible isolates. CONCLUSION: The findings showed that P-type ATPase and ubiquinone biosynthesis methyltransferase COQ5 might be involved in the CAS-resistance A. flavus clinical isolates. Moreover, a subset of genes was differentially expressed to enhance fungi survival in CAS exposure. Further studies are recommended to highlight the gene overexpression and knock-out experiments in A. flavus or surrogate organisms to confirm that these mentioned genes confer the CAS resistant A. flavus.

BACKGROUND: We examined the safety and efficacy of a treatment protocol containing Favipiravir for the treatment of SARS-CoV-2. METHODS: We did a multicenter randomized open-labeled clinical trial on moderate to severe cases infections of SARS-CoV-2. Patients with typical ground glass appearance on chest computerized tomography scan (CT scan) and oxygen saturation (SpO2) of less than 93% were enrolled. They were randomly allocated into Favipiravir (1.6 gr loading, 1.8 gr daily) and Lopinavir/Ritonavir (800/200 mg daily) treatment regimens in addition to standard care. In-hospital mortality, ICU admission, intubation, time to clinical recovery, changes in daily SpO2 after 5 min discontinuation of supplemental oxygen, and length of hospital stay were quantified and compared in the two groups. RESULTS: 380 patients were randomly allocated into Favipiravir (193) and Lopinavir/Ritonavir (187) groups in 13 centers. The number of deaths, intubations, and ICU admissions were not significantly different (26, 27, 31 and 21, 17, 25 respectively). Mean hospital stay was also not different (7.9 days [SD = 6] in the Favipiravir and 8.1 [SD = 6.5] days in Lopinavir/Ritonavir groups) (p = 0.61). Time to clinical recovery in the Favipiravir group was similar to Lopinavir/Ritonavir group (HR = 0.94, 95% CI 0.75 - 1.17) and likewise the changes in the daily SpO2 after discontinuation of supplemental oxygen (p = 0.46) CONCLUSION: Adding Favipiravir to the treatment protocol did not reduce the number of ICU admissions or intubations or In-hospital mortality compared to Lopinavir/Ritonavir regimen. It also did not shorten time to clinical recovery and length of hospital stay.

The new severe acute respiratory syndrome- coronavirus 2 is reported to affect the nervous system. Among the reports of the various neurological manifestations, there are a few documented specific processes to explain the neurological signs. We report a para-infectious encephalitis patient with clinical, laboratory, and imaging findings during evolution and convalescence phase of coronavirus infection. This comprehensive overview can illuminate the natural history of similar cases. As the two previously reported cases of encephalitis associated with this virus were not widely discussed regarding the treatment, we share our successful approach and add some recommendations about this new and scarce entity.

Hydatid disease commonly involves liver but in rare cases, it can involve cardiac structures. A 75-yr-old farmer from Parsabad-Moghan, northwestern Iran was presented to the Emergency Room of Tehran Imam Khomeini Hospital, Tehran, Iran with dyspnea and without chest pain in 2014. A lesion compatible with hydatid cyst was found in echocardiography and confirmed by serology and MRI. Surgical treatment was done but the patient was died in recovery room because of cardiac arrhythmia. In endemic areas, hydatid cyst should be considered in differential diagnosis of heterogeneous echogenic lesions even if the serologic tests are negative. Physician can use cardiac MRI to earn valuable information about the lesion and its relation to other structures. However, with all of these assessments, surgical removal of cardiac cysts may have some complications.
RESUMO
BACKGROUND: There is little data about the correlation between the outcome of community acquired pneumonia (CAP) and the hypercapnic type respiratory failure. In this study we prospectively investigated the prognostic significance of first arterial CO2 tension in patients hospitalized with CAP. METHODS: In this prospective study patients with CAP, admitted to a general hospital were included. PaCO2 was measured for each subject in an arterial blood sample drawn in the first 2 hours and its correlations with three major outcomes were evaluated: intensive care unit (ICU) admission, duration of admission and mortality in 30 days. RESULTS: A total of 114 patients (mean age: 60.9±18.3; male: 51.8%) diagnosed with CAP were included. Significant relationship was not found between PaCO2 and mortality (P=0.544) or ICU admission (P=0.863). However advanced age, associated CHF, high BUN levels, high CURB-65 scores, associated pleural effusion in chest X-ray and being admitted to the ICU (P=0.012, 0.004, 0.003, <0.001, 0.045 and <0.001 respectively) were all significant prognostic factors of higher mortality risks. Prognostic factors for ICU admission were a history of malignancy (P=0.004), higher CURB-65 (P<0.001) scores and concomitant pleural effusion (P=0.028) in chest X-ray. Hypercapnic patients hospitalized for longer duration compared with normocapnic subjects. Furthermore, patients with lower pH (P=0.041) and pleural effusions (P=0.002) were hospitalized longer than the others. CONCLUSIONS: There was less prominent prognostic value regarding on-admission PaCO2 in comparison to other factors such as CURB-65. Considering the inconsistent results of surveys conducted on prognostic value of PaCO2 for CAP outcomes, further investigations are required to reach a consensus on this matter.
