Aspergillus infection is a well-known complication of severe influenza and severe acute respiratory syndrome coronavirus (SARS-CoV), and these infections have been related with significant morbidity and mortality even when appropriately diagnosed and treated. Recent studies have indicated that SARS-CoV-2 might increase the risk of invasive pulmonary aspergillosis (IPA). Here, we report the first case of Aspergillus ochraceus in a SARS-CoV-2 positive immunocompetent patient, which is complicated by pulmonary and brain infections. Proven IPA is supported by the positive Galactomannan test, culture-positive, and histopathological evidence. The patient did not respond to voriconazole, and liposomal amphotericin B was added to his anti-fungal regimen. Further studies are needed to evaluate the prevalence of IPA in immunocompetent patients infected with SARS-CoV-2. Consequently, testing for the incidence of Aspergillus species in lower respiratory secretions and Galactomannan test of COVID-19 patients with appropriate therapy and targeted anti-fungal therapy based on the primary clinical suspicion of IPA are highly recommended.

Coronavirus Disease-2019 Pneumonia and Pulmonary Embolism: Presentation of Four Cases.

Indian J Crit Care Med 2020 Sep;24(9):873-876

Department of Pulmonology, Amin Hospital, Isfahan University of Medical Sciences, Isfahan, Iran.

Since the beginning of the Coronavirus Disease-2019 (COVID-19) outbreak, elevated D-dimer levels as an acute-phase reactant have been reported in some patients. Additionally, the patients with pneumonia are at increased risk of developing thromboembolic events. Diagnosing acute pulmonary embolism and deep vein thrombosis can be challenging in SARS-CoV2-positive patients. Here, we report four patients with COVID-19 pneumonia to highlight the possibility of acute thromboembolism in these patients. The physicians should be aware of this complication and even consider prophylactic anticoagulant therapy in proper clinical settings. Alikhani F, Aalinezhad M, Haji Rezaei M, Akbari P, Hashemi M.

Structural Assessment of Hydrogen Bonds on Methylpentynol-Azide Clusters To Achieve Regiochemical Outcome of 1,3-Dipolar Cycloaddition Reactions Using Density Functional Theory.

ACS Omega 2020 Mar 10;5(11):5964-5975. Epub 2020 Mar 10.

Department of Organic Chemistry, Faculty of Chemistry, Razi University, 67149-67346 Kermanshah, Iran.

This study was focused on the geometries and properties of the structural isomers obtained from a random walk of methylpentynol-HN clusters. The theoretical aspects of hydrogen bonding effects on the discussed 1,3-dipolar cycloaddition (1,3-DC) reactions [between methylpentynol () as a dipolarophile and azide () as a 1,3-dipole] have shown regioselective output concepts. The dipolarophile methylpentynol () was applied for the treatment of insomnia. Both methylpentynol () and azide () can be H-bond acceptor and H-bond donor agents. Because of this trait of them, structures of H-bonding arrays () and methylpentynol-azide clusters () can be probable. In this work, regioselectivity of the 1,3-DC reaction [between methylpentynol () as a dipolarophile and azide () as a 1,3-dipole] was determined based on these structures () using density functional theory (DFT). The energy levels of the reactants ( and ) and the structures of H-bonding arrays (), methylpentynol-azide clusters (), transition states, and products ( and ) were studied, and also, the free energies of the reaction (Δ and Δ, in kcal mol) and rate constants were determined using Eyring's equation (). Structural data were calculated and obtained by the DFT/B3LYP method. Seven different basis sets have been used to obtain the most appropriate results from comparison of data.

The utility of elastography during EBUS-TBNA in a population with a high prevalence of anthracosis.

Clin Respir J 2020 May 19;14(5):488-494. Epub 2020 Feb 19.

Tracheal Diseases Research Center, National Research Institute of Tuberculosis and Lung Diseases (NRITLD), Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Background: Ultrasound elastography, is a pioneer sonographic modality that is conducted during endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in order to increase the accuracy of sampling location. The current study aims to evaluate the usefulness of elastography during EBUS-TBNA in a population with a high prevalence of anthracosis.

Methods: This prospective single-blinded study was performed on 69 lymph nodes (LNs) of patients with mediastinal lymphadenopathy undergoing EBUS-TBNA and EBUS-elastography from October 2017 to July 2018. The stiffness level of the tissue was translated into a color to demonstrate the hardness of tissue. Blue and total areas of each section were measured to calculate the hardness of each LN.

Results: Sixty-nine LNs were evaluated by elastography. Twenty percent of LNs were malignant. There was a statistical difference between malignant and non-malignant nodes based on color dominancy (P = 0.032). However, with the exclusion of anthracosis nodes from the analysis, the difference was more significant (P < 0.001). Moreover, when the blue dominancy was used as the predictor of malignancy or anthracosis, the results showed a significant correlation (P < 001).

Conclusion: The usefulness of elastography in selecting the hardest area of tissue that is appropriate for diagnosing diseases has been proven previously. Since in countries with a high prevalence of anthracosis, blue color achieved using elastography predicts either malignancy or anthracosis so, cases with blue dominancy of LNs in elastography and the white color in the EBUS-TBNA indicate anthracosis-caused calcification should be reconsidered.

Real Time Polymerase Chain Reaction for Hepatitis B Screening in Donor Corneas in the Central Eye Bank of Iran.

J Ophthalmic Vis Res 2018 Oct-Dec;13(4):392-396

Central Eye Bank of Iran, Tehran, Iran.

Purpose: The aim of this study was to report the results of the use of real-time polymerase chain reaction (PCR) for the diagnosis of hepatitis B virus (HBV) infection in cornea donors at the Central Eye Bank of Iran.

Methods: Between 2014 and 2016, all cornea donors that had negative screening serologic results for hepatitis B (HB) surface antigen, HB surface antibody (Ab), hepatitis C virus Ab, human immune deficiency virus Ab, human T-cell leukemia virus Ab, and syphilis, and positive serology for HB core Ab were subjected to real-time PCR with a detection limit of 400 IU/mL to identify HBV DNA. Positive results for HBV DNA were considered occult HBV infections in these donors.

Results: Over the 3-year period, 122 out of 10448 cornea donors had negative screening serologic tests outside of HB core Ab. Of which, 90 cases were subjected to real-time PCR. Occult HBV was detected in 11 cases (12.2%), resulting in the rejection of the corresponding corneas. The remaining 79 cases (87.8%) had negative results for HBV DNA and the corresponding corneas were used for transplantation.

Conclusion: Implementation of PCR for the detection of occult HBV in cornea donors is necessary to not only increase the security level of cornea donation but also minimize the rejection rate of donors that have isolated HB core Ab reactivity.

Assessemnt of nasal bone in first trimester screening for chromosomal abnormalities in Khuzestan.

Iran J Reprod Med 2014 May;12(5):321-6

Department of obstetrics and Gynecology, Ahvaz Jundishapour University of Medical Sciences, Ahvaz, Iran.

Background: Fetal nasal bone assessment is a non-invasive procedure that helps provide even greater assurance to patients undergoing their first trimester risk assessment for aneuploidies. Absence or presence of this factor is different in some races.

Objective: The study was aimed to evaluate nasal bone in the first trimester of pregnancy in the indigenous population of Khuzestan Province, and to monitor its value in the diagnosis of chromosomal abnormalities.

Materials And Methods: This study was conducted on 2314 pregnant women between 17-43 years old who referred for first trimester screening for chromosomal abnormalities. Gestational age was between 11-13w + 6 days. Nuchal translucency (NT), fetal heart rate (FHR), crown rump length (CRL), and maternal age and maternal blood serum factors (Free HCG) and pregnancy-associated plasma protein-A (PAPP-A) and nasal bone were assessed. Finally the risk of trisomies was calculated. The statistical tests are based on the relationship between chromosomal abnormality and the presence or absence of the nasal bone.

Results: In 114 cases we could not examine the nasal bone. Also, in 20 cases missed abortion happened without knowing the karyotype. 2173 cases were delivered normal baby, and in seven cases chromosomal abnormalities were diagnosed. Nasal bone was absent in all three cases with trisomy 21 and six of 2173 cases with normal phenotype (0.3%). With use of the Fisher exact test (p=0.0001), a significant correlation was found between the absence of the nasal bone and the risk of chromosomal abnormality.

Conclusion: Inclusion of the nasal bone in first-trimester combined screening for aneuploidies achieves greater detection rate especially in Down syndrome.

Should We Look for Celiac Disease among all Patients with Liver Function Test Abnormalities?

Int J Prev Med 2012 Mar;3(3):167-72

Department of Gastroenterology and Hepatology, Isfahan University of Medical Sciences, Isfahan, Iran.

Background: Celiac disease (CD) has been found in up to 10% of the patients presenting with unexplained abnormal liver function tests (LFT). As there is no precise data from our country in this regard, we investigated the prevalence of CD in patients presenting with abnormal LFT.

Methods: From 2003 to 2008, we measured IgA anti-tissue transglutaminase (t-TG) antibody (with ELISA technique) within the first-level screening steps for all patients presenting with abnormal LFT to three outpatient gastroenterology clinics in Isfahan, IRAN. All subjects with an IgA anti-tTG antibody value of >10 μ/ml (seropositive) were undergone upper gastrointestinal endoscopy and duodenal biopsy. Histopathological changes were assessed according to the Marsh classification. CD was defined as being seropositive with Marsh I or above in histopathology and having a good response to gluten free diet (GFD).

Results: During the study, 224 patients were evaluated, out of which, 10 patients (4.4%) were seropositive for CD. Duodenal biopsies were performed in eight patients and revealed six (2.7%) cases of Marsh I or above (four Marsh IIIA, two Marsh I), all of them had good response to GFD. The overall prevalence of CD among patients with hypertransaminasemia, autoimmune hepatitis, and cryptogenic cirrhosis was determined as 10.7% (3/28), 3.4% (2/59), and 5.3% (1/19), respectively.

Conclusion: Serological screening with IgA anti-tTG antibody test should be routinely performed in patients presenting with abnormal LFT and especially those with chronic liver diseases including hypertransaminasemia, autoimmune hepatitis, and cryptogenic cirrhosis.

How frequent is celiac disease among epileptic patients?

J Gastrointestin Liver Dis 2008 Dec;17(4):379-82

Isfahan University of Medical Sciences (UMS) and Poursina Hakim Institute (PHRI), Isfahan, Iran.

Background: A variety of neurological disorders have been reported in association with celiac disease (CD) including epilepsy, ataxia, neuropathy and multifocal leucoencephalopathy. The purpose of this study was to assess the prevalence of CD among epileptic patients.

Methods: Our study population consisted of 108 consecutive unexplained epileptic patients from Epilepsy Clinics. Patients who were able to give informed consent were invited to undergo screening for CD in a gastroenterology clinic. The diagnosis of CD was determined by IgA anti-tissue transglutaminase (t-TG) antibodies and by small intestine biopsy. Histopathologic changes were interpreted according to the Marsh classification.

Results: A total of 108 consecutive epileptic patients (72 females, 36 males) ranging from 2-64 years (mean: 23.44, SD: 12.1) were studied. Positive IgA anti t-TG were detected in 4 of 108 epileptic patients (3.7%), while the known prevalence of CD in the study area was 0.6%.The intestinal biopsy confirmed the diagnosis of CD in three patients and was interpreted as Marsh I. In the other patient, small intestinal biopsy indicated only slightly increased number of intraepithelial lymphocytes. There was a significant difference between patients with CD and without CD for two symptoms: diarrhea and aphtous lesions (p<0.05).

Conclusion: Prevalence of CD was increased among patients with epilepsy of unknown etiology. It is important to investigate CD in any patient with idiopathic epilepsy even in the absence of digestive symptoms.

Diagnostic accuracy of IgA anti-tissue transglutaminase in patients suspected of having coeliac disease in Iran.

J Gastrointestin Liver Dis 2008 Jun;17(2):141-6

Poursina Hakim Research Institute & Isfahan University of Medical Science, Bozorgmehr Avenue, Isfahan, Iran.

Background And Aim: As there are little data about the sensitivity of the IgA anti-tissue transglutaminase (IgA anti-tTG) antibody test in the clinical practice setting, we evaluated the sensitivity of this serologic test in a group of patients who were suspected of having coeliac disease and had serologic testing performed at commercial laboratories.

Patients And Methods: The study was performed at Poursina Hakim Research Institute in Isfahan-Iran. A total number of 350 consecutive patients were enrolled in our study. They were divided into 3 groups: classical mode of presentation, atypical mode of presentation and patients with non specific prolonged gastrointestinal symptoms. Upper gastrointestinal endoscopy, histopathologic examination of biopsies from the second part of duodenum and serologic evaluation were performed for every patient. Biopsy specimens were evaluated according to Marsh (1992, revised in 1997).

Results: The overall sensitivity and specificity of IgA anti-tTG antibody were 38% and 98%. The positive and negative predictive values for the anti-tTG antibodies were 57% and 96%, respectively. The sensitivity was 80% in patients with Marsh IIIC.

Conclusion: In contrast to other reports suggesting a diagnostic accuracy of more than 90% for anti-tTG antibody in coeliac disease patients, our data showed that we are still far from an ideal screening serologic tool which can rely on the antibody test as the sole way of identifying patients with coeliac disease. This could result in many missed diagnoses, in particular in patients with lesser degrees of Marsh classification.
