Abstract
The human immune system responds to harmful foreign invaders frequently encountered by the body and employs defense mechanisms to counteract such assaults. Various exogenous and endogenous factors play a prominent role in maintaining the balanced functioning of the immune system, which can result in immune suppression or immune stimulation. With the advent of different immune-modulatory agents, immune responses can be modulated or regulated to control infections and other health effects. Literature provides evidence on various immunomodulators from different sources and their role in modulating immune responses. Due to the limited efficacy of current drugs and the rise in drug resistance, there is a growing need for new therapies for infectious diseases. In this review, we aim to provide a comprehensive overview of different immune-modulating agents and immune therapies specifically focused on viral infectious diseases.

Abstract
Pentoxifylline (PTX), a non-selective phosphodiesterase inhibitor, has demonstrated protective effects against lung injury in animal models. Given the significance of pulmonary toxicity resulting from paraquat (PQ) exposure, the present investigation was designed to explore the impact of PTX on PQ-induced pulmonary oxidative impairment in male mice.Following preliminary studies, thirty-six mice were divided into six groups. Group 1 received normal saline, group 2 received a single dose of PQ (20 mg/kg; i.p.), and group 3 received PTX (100 mg/kg/day; i.p.). Additionally, treatment groups 4-6 were received various doses of PTX (25, 50, and 100 mg/kg/day; respectively) one hour after a single dose of PQ. After 72 hours, the animals were sacrificed, and lung tissue was collected.PQ administration caused a significant decrease in hematocrit and an increase in blood potassium levels. Moreover, a notable increase was found in the lipid peroxidation (LPO), nitric oxide (NO), and myeloperoxidase (MPO) levels, along with a notable decrease in total thiol (TTM) and total antioxidant capacity (TAC) contents, catalase (CAT) and superoxide dismutase (SOD) enzymes activity in lung tissue. PTX demonstrated the ability to improve hematocrit levels; enhance SOD activity and TTM content; and decrease MPO activity, LPO and NO levels in PQ-induced pulmonary toxicity. Furthermore, these findings were well-correlated with the observed lung histopathological changes.In conclusion, our results suggest that the high dose of PTX may ameliorate lung injury by improving the oxidant/antioxidant balance in animals exposed to PQ.

Abstract
Coronavirus disease 2019 (COVID-19) can manifest with ocular symptoms. These symptoms can be divided into isolated events attributed to COVID-19, and those occurring in multisystem inflammatory syndrome in children (MIS-C), a newly diagnosed disease entity associated with COVID-19 infection. Currently, the literature lacks specific guidelines and treatment regimens for COVID-19 ocular symptoms, especially in children. The authors present the case of a 14-and-a-half-year-old boy with bilateral uveitis of the anterior and posterior segments along with vasculitis and optic neuritis associated with SARS-CoV-2 infection. The authors also perform an up-to-date review of all available publications on the treatment of post-COVID-19 uveitis in children described in the literature between 2020 and 2023. In the case described by the authors, the treatment involved a Depo-Medrol 40 mg/mL injection uder the Tenon capsule, with two subconjunctival injections of epinephrine, topical steroid therapy and non-steroidal anti-inflammatory drugs: dexamethasone 0.1%; diclofenac eye drops. In addition, acetylsalicylic acid (150 mg) and pentoxifylline (100 mg, orally) were administered throughout the course of the disease as well as up to 12 months after its termination, until a complete improvement in visual acuity and the withdrawal of ocular lesions were achieved. It can be assumed that this type of treatment is far more beneficial for pediatric patients, with an effect comparable to systemic steroid administration with a preserved improvement in retinal-vascular circulation, without exposing the child to systemic post-steroid complications.

Abstract
INTRODUCTION Despite the ever-increasing occurrences of the coronavirus disease (COVID-19) cases around the world, very few medications have been validated in the clinical trials to combat COVID-19. Although several vaccines have been developed in the past quarter, the time elapsed between deployment and administration remains a major impediment. CONTENT Repurposing of pre-approved drugs, such as phosphodiesterase 5 (PDE5) inhibitors, could be a game-changer while lessening the burden on the current healthcare system. Repurposing and developing phosphodiesterase 5 (PDE5) inhibitors could extrapolate their utility to combat the SARS-CoV-2 infection, and potentially aid in the management of the symptoms associated with its newer variants such as BF.7, BQ.1, BQ.1.1, XBB.1.5, and XBB.1.16. SUMMARY Administration of PDE5 inhibitors via the oral and intravenous route demonstrates other potential off-label benefits, including anti-apoptotic, anti-inflammatory, antioxidant, and immunomodulatory effects, by intercepting several pathways. These effects can not only be of clinical importance in mild-to-moderate, but also moderate-to-severe SARS-CoV-2 infections. This article explores the various mechanisms by which PDE5 inhibitors alleviates the symptoms associated with COVID-19 as well as well as highlights recent studies and findings. OUTLOOK These benefits of PDE5 inhibitors make it a potential drug in the physicians' armamentarium in alleviating symptoms associated with SARS-CoV-2 infection. However, adequate clinical studies must be instituted to eliminate any untoward adverse events.

Evaluation of the efficacy and safety of oral N-acetylcysteine in patients with COVID-19 receiving the routine antiviral and hydroxychloroquine protocol: A randomized controlled clinical trial. Immun Inflamm Dis 2023; 11:e1083. [PMID: 38018602 PMCID: PMC10659758 DOI: 10.1002/iid3.1083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 10/25/2023] [Accepted: 10/31/2023] [Indexed: 11/30/2023] Open
Abstract
BACKGROUND The current absence of gold-standard or all-aspect favorable therapies for COVID-19 renders a focus on multipotential drugs proposed to prevent or treat this infection or ameliorate its signs and symptoms vitally important. The present well-designed randomized controlled trial (RCT) sought to evaluate the efficacy and safety of N-acetylcysteine (NAC) as adjuvant therapy for 60 hospitalized Iranian patients with COVID-19. METHODS Two 30-person diets, comprising 15 single diets of Kaletra (lopinavir/ritonavir) + hydroxychloroquine (HCQ) with/without NAC (600 mg TDS) and atazanavir/ritonavir + HCQ with/without NAC (600 mg TDS), were administered in the study. RESULTS At the end of the study, a further decrease in C-reactive protein was observed in the NAC group (P = 0.008), and no death occurred in the atazanavir/ritonavir + HCQ + NAC group, showing that the combination of these drugs may reduce mortality. The atazanavir/ritonavir + HCQ and atazanavir/ritonavir + NAC groups exhibited the highest O2 saturation at the end of the study and a significant rise in O2 saturation following intervention commencement, including NAC (P > 0.05). Accordingly, oral or intravenous NAC, if indicated, may enhance O2 saturation, blunt the inflammation trend (by reducing C-reactive protein), and lower mortality in hospitalized patients with COVID-19. CONCLUSION The NAC could be more effective as prophylactic or adjuvant therapy in stable non-severe cases of COVID-19 with a particularly positive role in the augmentation of O2 saturation and faster reduction of the CRP level and inflammation or could be effective for better controlling of COVID-19 or its therapy-related side effects.

Abstract
Inhalation of high concentrations of phosgene often causes pulmonary edema, which obstructs the airway and causes tissue hypoxia. There is currently no specific antidote. This study was performed to investigate the effect behind pentoxifylline (PTX) treatment for phosgene-induced lung injury in rat models. Rats were exposed to phosgene. The protein levels of hypoxia-inducible factor-1α (HIF-1α), vascular endothelial growth factor (VEGF), and occludin proteins in lung tissue were determined. The effect of both prophylactic and therapeutic administration of PTX (50 mg/kg and 100 mg/kg) was evaluated. The lung permeability index and HIF-1α protein level increased, the arterial blood oxygenation index (PaO2/FIO2 ratio) and occludin protein level decreased significantly 6 h after phosgene exposure (P < 0.05). PTX exerted protective effects by HIF-1α-VEGF-occludin signaling pathway to some extent. Moreover, prophylactic, but not therapeutic administration of PTX (100 mg/kg), exhibited a significant protective effect. Pretreatment with PTX protected against phosgene-induced lung injury, possibly by inhibiting differential expression of HIF-1α, VEGF, and occludin.

Abstract
Rapid and proper diagnosis of mucocutaneous presentations of COVID-19 which in many cases are representing internal organ damage is a key way to better approach these patients, and it could be even lifesaving. In this original study, we reported consultant critical and non-critical cases of admitted COVID-19 patients and some interesting outpatient cases for 14 months, and some newly encountered vaccine-associated dermatoses. We presented 121 cases divided into 12 categories; all had full multi-aspects photographs attached as an atlas to a Supplementary File. These categories were:1- Generalized papulopustular eruptions (3 patients), 2- Erythroderma (4 patients), 3- Maculopapular lesions(16 patients), 4- Mucosal lesions (8 patients), 5- Urticarial lesions and angioedema (16 patients), 6- Vascular injuries (22 patients), 7- Vesiculobullous lesions (12 patients), 8- The specific new onset of mucocutaneous presentations or aggravation of any especial previous dermatoses (9 patients), 9- Nail changes (3 patients), 10- Hair loss (2 patients), 11- Non-specific mucocutaneous problems (16 patients) and 12-Vaccine-associated dermatoses (10 patients).In the pandemic, if we countered with extensive mucocutaneous lesions with vascular components or vesiculobullous erosive lesions in association with any cutaneous rash that could be an alarming sign of a probable life-threatening systemic event, we would need to approach them as soon as possible.

Abstract
COVID-19 is a fatal, fast-spreading pandemic, and numerous attempts are being made around the world to understand and manage the disease. COVID-19 patients may develop a cytokine-release syndrome, which causes serious respiratory diseases and, in many cases, death. The study examined the feasibility of employing legally available anti-inflammatory pentoxifylline (PTX), a low toxicity and cost medication, to mitigate the hyper-inflammation caused by COVID-19. Thirty adult patients who tested positive for SARS-CoV2 were hospitalized owing to the cytokine storm syndrome. They were given 400 mg of pentoxifylline orally TID according to the standard COVID-19 protocol of the Egyptian Ministry of Health. Besides this, a group of thirty-eight hospitalized COVID-19 patients who received the standard COVID-19 protocol was included in the study as a control group. The outcomes included laboratory test parameters, clinical improvements, and number of deaths in both groups. After receiving PTX, all patients showed a significant improvement in C reactive protein (CRP), and interleukin-6 (IL-6) levels at p < 0.01 and p = 0.004, respectively, while there was an increase in total leukocyte count (TLC) and neutrophil-to-leucocyte ratio (NLR) at p < 0.01 compared to their baseline levels. The D-dimer level showed a significant increase in the treatment group at p < 0.01, while showing no statistically significant difference in the control group. The median initial ALT (42 U/L) in the treatment group showed a decrease compared to the control group (51 U/L). No statistical significance was reported regarding clinical improvement, length of stay, and death percentages between the two groups. Our results showed no significant improvement of PTX over controls in clinical outcomes of hospitalized COVID-19 patients. Nevertheless, PTX displayed a positive effect on certain inflammatory biomarkers.

The Role of Exosomes in Pancreatic Ductal Adenocarcinoma Progression and Their Potential as Biomarkers. Cancers (Basel) 2023; 15:cancers15061776.

Abstract
Pancreatic ductal adenocarcinoma (PDAC), the most common pancreatic malignancy, is an aggressive and lethal cancer with a dismal five-year survival rate. Despite remarkable improvements in cancer therapeutics, the clinical outcome of PDAC patients remains poor due to late diagnosis of the disease. This highlights the importance of early detection, wherein biomarker evaluation including exosomes would be helpful. Exosomes, small extracellular vesicles (sEVs), are cell-secreted entities with diameters ranging from 50 to 150 nm that deliver cellular contents (e.g., proteins, lipids, and nucleic acids) from parent cells to regulate the cellular processes of targeted cells. Recently, an increasing number of studies have reported that exosomes serve as messengers to facilitate stromal-immune crosstalk within the PDAC tumor microenvironment (TME), and their contents are indicative of disease progression. Moreover, evidence suggests that exosomes with specific surface markers are capable of distinguishing patients with PDAC from healthy individuals. Detectable exosomes in bodily fluids (e.g., blood, urine, saliva, and pancreatic juice) are omnipresent and may serve as promising biomarkers for improving early detection and evaluating patient prognosis. In this review, we shed light on the involvement of exosomes and their cargos in processes related to disease progression, including chemoresistance, angiogenesis, invasion, metastasis, and immunomodulation, and their potential as prognostic markers. Furthermore, we highlight feasible clinical applications and the limitations of exosomes in liquid biopsies as tools for early diagnosis as well as disease monitoring. Taking advantage of exosomes to improve diagnostic capacity may provide hope for PDAC patients, although further investigation is urgently needed.

Abstract
A series of physiological and pathological changes occur after radiotherapy and accidental exposure to ionizing radiation (IR). These changes cause serious damage to human tissues and can lead to death. Radioprotective countermeasures are radioprotective agents that prevent and reduce IR injury or have therapeutic effects. Based on a good understanding of radiobiology, a number of protective agents have achieved positive results in early clinical trials. The present review grouped known radioprotective agents according to biochemical categories and potential clinical use, and reviewed radiation countermeasures, i.e., radioprotectors, radiation mitigators and radiotherapeutic agents, with an emphasis on their current status and research progress. The aim of the present review is to facilitate the selection and application of suitable radioprotectors for clinicians and researchers, to prevent or reduce IR injury.

Abstract
Study Background & Objective: After the influenza pandemic (1918), COVID-19 was declared a Vth pandemic by the WHO in 2020. SARS-CoV-2 is an RNA-enveloped single-stranded virus. Based on the structure and life cycle, Protease (3CLpro), RdRp, ACE2, IL-6, and TMPRSS2 are the major targets for drug development against COVID-19. Pre-existing several drugs (FDA-approved) are used to inhibit the above targets in different diseases. In coronavirus treatment, these drugs are also in different clinical trial stages. Remdesivir (RdRp inhibitor) is the only FDA-approved medicine for coronavirus treatment. In the present study, by using the drug repurposing strategy, 70 preexisting clinical or under clinical trial molecules were used in scrutiny for RdRp inhibitor potent molecules in coronavirus treatment being surveyed via docking studies. Molecular simulation studies further confirmed the binding mechanism and stability of the most potent compounds. MATERIAL AND METHODS Docking studies were performed using the Maestro 12.9 module of Schrodinger software over 70 molecules with RdRp as the target and remdesivir as the standard drug and further confirmed by simulation studies. RESULTS The docking studies showed that many HIV protease inhibitors demonstrated remarkable binding interactions with the target RdRp. Protease inhibitors such as lopinavir and ritonavir are effective. Along with these, AT-527, ledipasvir, bicalutamide, and cobicistat showed improved docking scores. RMSD and RMSF were further analyzed for potent ledipasvir and ritonavir by simulation studies and were identified as potential candidates for corona disease. CONCLUSION The drug repurposing approach provides a new avenue in COVID-19 treatment.

Dermatol Ther 2022; 35:e15639.

Abstract
Lichen planoplaris (LPP) is one of the most common causes of inflammatory cicatricial alopecias. There is no definitive cure for the disease and most of the available therapeutic options can potentially lead to serious complications following their use for extended durations. In this study, we aimed to evaluate the efficacy, safety and tolerability of N-acetylcysteine (NAC) and pentoxyfillin (PTX), as adjunctive therapies, in the management of LPP. In a randomized, assessor- and analyst-blinded controlled trial, patients with proven LPP were randomly assigned to three groups of 10. Group I (the control group) received clobetasol 0.05%lotion; Group II, a combination of clobetasol 0.05% lotion and oral PTX; Group III, a combination of clobetasol lotion 0.05% and oral NAC. Lichen planopilaris activity index (LPPAI), the possible side effects, tolerability and patients satisfaction were assessed before and two and four months after the initiation of the treatments. Thirty patients, 96.7% women, with a mean age of 46.8 ± 13.3 years old, were included in the study. Four months into the treatments, the overall LPPAI and the severity and/or frequency of most of its determinants significantly decreased in all groups. In a comparison among the groups, patients who received either of the combination therapies showed more decline in their LPPAI than those receiving only clobetasol. The decline was more noticeable and statistically significant only in the NAC group. Three patients in the PTX group developed complications that were not statistically significant when compared with the other groups. There were no substantial differences in the tolerability of the treatments among the study arms. The use of oral NAC and PTX added to the therapeutic efficacy of topical clobetasol in the treatment of LPP, suggesting that they might be beneficial and safe adjuvant therapies and add to the efficacy of topical treatment without any noticeable impact on the adverse effects experienced by patients.

A systematic review on mucocutaneous presentations after COVID-19 vaccination and expert recommendations about vaccination of important immune-mediated dermatologic disorders. Dermatol Ther 2022; 35:e15461. [PMID: 35316551 PMCID: PMC9111423 DOI: 10.1111/dth.15461] [Citation(s) in RCA: 23] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2021] [Revised: 03/14/2022] [Accepted: 03/17/2022] [Indexed: 11/29/2022]
Abstract
With dermatologic side effects being fairly prevalent following vaccination against COVID-19, and the multitude of studies aiming to report and analyze these adverse events, the need for an extensive investigation on previous studies seemed urgent, in order to provide a thorough body of information about these post-COVID-19 immunization mucocutaneous reactions. To achieve this goal, a comprehensive electronic search was performed through the international databases including Medline (PubMed), Scopus, Cochrane, Web of science, and Google scholar on July 12, 2021, and all articles regarding mucocutaneous manifestations and considerations after COVID-19 vaccine administration were retrieved using the following keywords: COVID-19 vaccine, dermatology considerations and mucocutaneous manifestations. A total of 917 records were retrieved and a final number of 180 articles were included in data extraction. Mild, moderate, severe and potentially life-threatening adverse events have been reported following immunization with COVID vaccines, through case reports, case series, observational studies, randomized clinical trials, and further recommendations and consensus position papers regarding vaccination. In this systematic review, we categorized these results in detail into five elaborate tables, making what we believe to be an extensively informative, unprecedented set of data on this topic. Based on our findings, in the viewpoint of the pros and cons of vaccination, mucocutaneous adverse events were mostly non-significant, self-limiting reactions, and for the more uncommon moderate to severe reactions, guidelines and consensus position papers could be of great importance to provide those at higher risks and those with specific worries of flare-ups or inefficient immunization, with sufficient recommendations to safely schedule their vaccine doses, or avoid vaccination if they have the discussed contra-indications.

Abstract
Background: In the last two decades, the world has witnessed the emergence of zoonotic corona viruses (CoVs), which cause mild to severe respiratory diseases in humans. Human coronaviruses (HCoVs), mainly from the alpha-CoV and beta-CoV genera, have evolved to be highly pathogenic, such as SARS-CoV-2 causing the COVID-19 pandemic. These coronaviruses carry functional enzymes necessary for the virus life cycle, which represent attractive antiviral targets. Methods & Results: We aimed to therapeutically target the main protease (Mpro) of HCoV-NL63 and HCoV-229E (from alpha-CoV genus) and HCoV-OC43 and SARS-CoV-2 (from beta-CoV genus). Through virtual screening, we identified an FDA-approved drug dyphylline, a xanthine derivate, that binds to the catalytic dyad residues; histidine and cystine of the Mpro structures. Importantly, dyphylline dose-dependently inhibited the viral replication in cell culture models infected with the viruses. Conclusion: Our findings support the repurposing of dyphylline as a pan-coronavirus antiviral agent.

Abstract
Mounting research has been performed and published on natural antioxidants, more so than on synthetic ones, as key molecules that control oxidative damage and its pathway to disease. Since the discovery of vitamins, various fully synthetic or natural-identical compounds have been developed as stable small molecules translated into constantly active and completely controlled products which are widely exploited in the food and pharmaceutical industries. There is currently a debate within the literature about their mechanism of action, bioavailability, safety and real benefit for human health. Using a semiquantitative method and eligible criteria of selection, this review aimed to provide a very useful classification of antioxidants and a comprehensive cross-disciplinary description of 32 approved synthetic/natural-identical antioxidants, in terms of regulatory, antioxidant mechanism of action, safety issues, pharmacological properties, effectiveness in human health, timeline and future trends. Enriched interpretation of the data was obtained from summary bibliometrics, useful to portray the “good antioxidant” within the period 1966–2021 and, hopefully, to encourage further research.

Abstract
Varicocele is recognized as one of the main attributable causes of male infertility which can affect spermatogenesis by various pathophysiological mechanisms. Recent studies have identified oxidative stress and reduction in antioxidant, hyperthermia, hypoxia, hormonal dysfunction, and inflammatory conditions as major factors in the pathophysiology of varicocele, all of which have known direct associations with the coronavirus disease 2019 (COVID-19) and can significantly increase the risk of detrimental COVID-19-related outcomes. Emerging data have shown an association between COVID-19 and inflammation, overproduction of cytokine, and other pathophysiological processes. The present review, summarizes the current understanding of the pathophysiology of varicocele and investigates the potential correlation between the severity of COVID-19 and the varicocele disease. In addition, various possible treatments which can be effective in both diseases were examined. Despite numerous challenges associated with the prevalence of COVID-19 in healthcare systems in infected countries, special attention should be given to maintaining a high level of care for complex patients with a pre-existing disease such as varicocele and providing appropriate practical advice for optimal control of the COVID-19 disease.

Abstract
While mucocutaneous manifestations of COVID-19 have been frequently reported and added to our knowledge every day during the pandemic, another issue is the COVID-related diseases that can present as intensified lesions of underlying diseases, a new disease, or changes in the behavior of an old lesion. Given that immune system overreaction and cytokine storm are among the most prominent events in COVID-19, the incidence of autoimmune diseases is expected to increase after COVID-19, as confirmed in several reports. To increase the body of knowledge about short- and long-term outcomes of COVID-19 for specialists, it is essential that similar cases be reported and collected for years to come. The present study investigated a case of pansclerotic morphea that rapidly progressed a few weeks after infection with COVID-19 in a 57-year-old woman with no history of any autoimmune skin or rheumatic diseases. She was prescribed outpatient COVID-19 treatment of azithromycin, vitamins D and C, and then quarantined for 2 weeks. The manifestations of the disease were exacerbated at each follow-up and sampling visit at short intervals. This kind of pansclerotic morphea is reported for the first time.

Abstract
As a respiratory viral infection caused by a novel coronavirus, COVID-19 became rapidly pandemic within a few months. Despite the wide range of manifestations and organ involvement in COVID-19 patients, the exact pathogenesis of severe and fatal types of COVID-19 and causes involved with the individual base of the disease is not yet understood. Several studies have reported clinical, laboratory, and histopathological data in favor of vascular injury in multiple organs of critically ill patients with COVID-19 as a result of hyperactive immune response, inflammation, and cytokine storm. Also, both clinical and histopathological evidence points to such vascular involvements in the skin. Given the ease of clinical examinations and skin biopsy and the lower risks of transmission of COVID-19 to healthcare workers, the present review article was conducted to investigate the vascular skin manifestations of COVID-19 patients clinically and/or histopathologically as helpful clues for better understanding the pathogenesis and predicting the prognosis of the disease, especially in severe cases.

Abstract
Objective. Manganese (Mn) has been reported, through dietary and occupational overexposure, to induce neurotoxicity named manganism. Pentoxifylline (PTX) administration attracts much attention considering the beneficial properties of PTX, as an anti-inflammatory and smooth muscle relaxation agent. This in vivo study aims to evaluate the effect of PTX on manganism in rat model. Materials and Methods. Thirty adult male Sprague Dawley rats received MnCl2 (100 mg/kg, i.p. on days 1, 3, and 7) during a week alone or in combination with PTX (300 mg/kg, i.p. every day for 8 consecutive days on manganism rat model). Several locomotor activity indices, as well as biomarkers of oxidative stress, were monitored in the brain tissue of Mn-exposed animals. Results. It was found that PTX supplementation (300 mg/kg, i.p.) deteriorated the Mn-induced locomotor deficit. This drug also increased the Mn brain accumulation as well as reactive oxygen species (ROS) and lipid peroxidation products in the manganism rat model. Moreover, the levels of total antioxidant capacity (TAC) and glutathione (GSH) were shown to be reduced significantly compared to the control group. Conclusion. The results of this study revealed that PTX at a high dose (300 mg/kg) might increase manganism complications. PTX lowers the blood viscosity, improves the tissue perfusion, and increases the Mn levels in the brain.

Abstract
Background: The COVID-19 infection is a novel virus without any specific targeted therapies; thus, focusing on primary epidemiologic concerns, preventive strategies, risk factors, exacerbation factors, and mortality-related factors are of great importance to better control this disorder. There are some controversies about the factors associated with COVID-19 in different theories, and addiction is no exception. Methods: We conducted a large cross-sectional study of 513 hospitalized Iranian patients with COVID-19 infection to evaluate the severity of disease courses in patients with or without history of opium addiction. We recorded these data retrospectively after patients' discharge from the hospital. For the quantitative data, we used independent-samples t and Mann-Whitney tests. The qualitative data were calculated using Fisher exact and chi-square tests in IBM SPSS Statistics Version 22. Also, p<0.05 was considered statistically significant. Results: There was no significant difference regarding mean days of hospitalization in opium positive and negative groups (7.95±8.39 vs 8.35±5.11, respectively) (p=0.771); however, the need for intensive care unit (ICU) admission was significantly higher in the opium positive group (36% vs 11%) (p=0.005). The mean days of ICU stay was significantly higher in the opium positive group (2.36±3.81 vs 0.86±2.90) (p=0.026). The percentage of febrile patients, anosmia/hyposmia, and dysgeusia at the initiation of hospitalization was significantly lower in the opium positive group (39% vs 66%; 8% vs 23%; 8% vs; 20%, respectively) (p=0.002, 0.018, and.031, respectively). In the laboratory tests, only the white blood cell (WBC) count and the segmented cells were higher in the opium positive group (10.1±6.60 vs 7.38±4.14 and 73±20.47 vs 56.5±32.60, respectively) (p=0.018 and.001, respectively) and lymphocytes were lower in the opium positive (15.60±8.25 vs18.70±10.12) (p=0.048). Opium addicts had a significantly lower rate of azithromycin and lopinavir/ritonavir prescription in their initiation therapy (19% vs 34%, and 47% vs 70%, respectively) (p=0.038 and 0.012, respectively). Conclusion: Opium addict patients with COVID infection may be more febrile and experience more disease-specific symptoms and more severe disease course. These patients may show more evidence of laboratory inflammation and probable superinfections, so may manage with more caution and somehow different therapeutic regimen.

The effect of influenza vaccine on severity of COVID-19 infection: An original study from Iran. Med J Islam Repub Iran 2021; 35:114. [PMID: 34956960 PMCID: PMC8683836 DOI: 10.47176/mjiri.35.114] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Indexed: 12/23/2022] Open
Abstract
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.

Abstract
BACKGROUND Rituximab is a FDA-approved monoclonal antibody for adults with moderate to severe potentially life-threatening pemphigus vulgaris. Recent studies have focused on assessments of efficacy and safety of low-dose rituximab (<2 gram in each cycle). METHOD Databases were searched from 2010 to 2020 (last update: 1 June 2020). RESULT Nine studies were entered; including180 cases (92: women, 88: men, age range: 9-83 years). The dosages of each Rituximab cycle varied between ultra-low-dose (≤500 mg for a cycle, either multiple infusions or a single infusion), low-dose (2 × 375 mg/m2 or 2 × 500 mg) and modified-dose (3 × 375 mg/m2 or 3 × 500 mg). The efficacy and safety of Rituximab in the studies are known by the recovery time, relapse time, and side events. According to the studies, 2 × 500 can lead to complete remission in a broad range, from 35 to 82%. These differences might be explained by different end-points and variable cumulative corticosteroid dosage after RTX administration. Although the studies showed that low dose RTX is efficient, there are some controversies regarding the choosing low-dose for severe patients. CONCLUSION Considering the effectiveness of low-dose, intermediate dose, and ultra-low-dose protocols of Rituximab in inducing remission in pemphigus disease and considering factors such as cost of therapy, and the need to induce a minimum of immunosuppression for a minimum duration in the COVID-19 pandemic, suggested to use low-dose Rituximab protocol (2 infusions of 500 mg Rituximab: interval of 2 weeks) to induce the remission in mild-to-moderate pemphigus patients.

Abstract
The mucocutaneous manifestations of Corona Virus Disease 2019 (COVID‐19) logically may reflect systemic visceral involvements. These findings are visible and easy to approach like biopsies for exact histopathologic evaluations. This systematic review was conducted to collect the mucocutaneous histopathologic data of COVID‐19 patients for future investigations and interpretations. The COVID‐19 dermatology resource of the Centre of Evidence‐Based Dermatology (CEBD) at the University of Nottingham, PubMed, Scopus, Google Scholar and Medscape was searched for relevant English articles published by June 3, 2020. This review included 31 articles, involving 459 patients. The common primary virus‐related mucocutaneous manifestations are easy to approach in the course of COVID‐19. The authors of this study supposed dermatopathological findings as the predictors of the nature of potential systemic involvements and outcomes of COVID‐19. Scrutinizing these findings can help with adopting more effective therapeutic and management strategies; nevertheless, this review found the severity and time of onset of symptoms not to be associated with the laboratory and histopathological findings. Deterioration of clinical conditions and laboratory tests was also not related to the histopathological findings. It is recommended that meta‐analyses be conducted in the future to detail on these data for having more comprehensive and better conclusion.

Abstract
COVID-19 was first discovered in Wuhan, China, and has spread rapidly around the world. The most important manifestation of COVID-19 was ARDS-like lung injury at first, but the involvement of other organs, such as kidney, heart, liver, and skin, was gradually reported. It is important to report and share all atypical manifestations of this disease to help other physicians to gain more knowledge about this new viral disease. As mentioned, there are also studies that show different types of cutaneous involvement in these patients, but due to the lack of more detailed studies in this field, and on the other hand, the possible usefulness of skin lesions as a diagnostic or alarming sign in the COVID-19 era, in this study we report a COVID-19 patient with a large hemorrhagic blister similar to sepsis-induced skin lesion. Despite the lack of common symptoms of the disease, the lung scan of the patient was positive for COVID-19.

Abstract
Background: In the pandemic era of Coronavirus disease 19 (COVID-19), one of the most important issues is the nature of real pathological events that occur during disease course in different parts of the body. There are several ways to know more about COVID-related histopathological events,such as tissue sampling which means biopsy from the tissues of either livepeople or necropsy/autopsy of people who died from COVID-19. Methods: We conducted an original study for assessing histopathological findings of lung necropsy samples collected from 15 Iranian patients.The continuous variables were presented as mean and standard deviation, and for the qualitative data on histopathological findings, the percentage or qualitative scores (0 to +3) were used. Results: We found similar presentations of COVID-related histopathologic events regarding percentage and severity in pulmonary tissue, includinglymphocytic infiltrations, inflammatory infiltrations of septal and perivascular areas, desquamated type2 pneumocytes, hyaline membrane changes, fibrin material depositions, abnormal changes of alveolar capillaries, presence of megakaryocytes, PMN infiltrations, septal necrosis, microabscess formation and bacterial colony formation. Also, we found few interesting features which were not completely compatible with previous similar studies or newly reported by ours asa high percentage of anthracosis (86%: 13 patients) that was not clearly reported in other previous studies, also a lower percentage of microthrombotic vascular lung injuries (20%: 3 patients), and a higher percentage of viral cytopathic effects (27%: 4 patients). Conclusion: This article suggests a greater need for evaluatingthe autopsy samples of COVID-19 patients to provide better management strategies and propose the question of whether anthracosismay be a mortality risk factor in COVID-19 patients.

Abstract
Acne vulgaris is one of the most common dermatologic disorders affects people of all races and ethnicities and has many adverse effects on the quality of life. The increased bacterial resistance to antibiotics has reduced the effectiveness of treatment with these agents. There is an increasing focus on the involvement of oxidative stress in the pathophysiology of acne. This study investigates the effect of N-acetylcysteine (NAC) as an antioxidant in the treatment of acne vulgaris. This systematic review was conducted through a search in databases such as Science Direct, PubMed, Scielo, and Medline using keywords including acne vulgaris, anti and NAC, and all the keywords associated with each of the subtitles. The factors affecting the occurrence and expansion of acne include increased sebum synthesis, hyperkeratinization of pilosebaceous units, colonization with Propionibacterium acnes, and increased release of inflammatory mediators and ROS. Studies have shown that glutathione stimulation following the administration of NAC increases glutathione levels for the detoxification of oxygen-free radicals. Moreover, NAC prevents the synthesis and release of inflammatory cytokines such as TNF-α, IL-8, IL-6, MP9, and IL-1β and has shown antibacterial activities against important bacteria including E. coli, S. epidermidis, Pseudomonas, and Klebsiella. This medication has anti-proliferative effects and is also used for excoriation and PCOD. The results of the present study showed the beneficial effects of using NAC in patients with acne vulgaris in terms of the disease complications and comorbidities. Given its diverse functional mechanisms, this medication can be used to treat acne and its consequences.

Abstract
In December 2019, a new coronavirus, named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), emerged from China, causing pneumonia outbreaks first in the Wuhan region and has now spread worldwide. There are no specific drugs for the disease caused by this virus, coronavirus disease 2019 (COVID-19). Considering that new synthesized drugs cannot be applied immediately to patients, conventional drug in new use is a feasible solution. Chloroquine, remdesivir, favipiravir, lopinavir, ribavirin, and ritonavir have shown efficacy to inhibit coronavirus in vitro. Pentoxifylline, a drug with anti-inflammatory, immunomodulatory, and bronchodilatory effects, has previously been shown to inhibit several viral infections. Immunological studies have shown that most patients with severe COVID-19 exhibit substantially elevated serum levels of pro-inflammatory cytokines. Pentoxifylline is a phosphodiesterase inhibitor that increases the levels of cyclic adenosine monophosphate, which in turn activates protein kinase, leading to a reduction in the synthesis of pro-inflammatory cytokines and immune cell migration. Here, we propose pentoxifylline, a drug with low cost and toxicity, as a possible treatment for COVID-19 based on its interesting properties.

Abstract
INTRODUCTION The recent global outbreak of coronavirus disease 2019 (COVID-19) has become a pandemic with a lot of sufferers. Excessive inflammation, exaggerated immune response, with ultimate apoptosis contribute to COVID-19 pathology that progress to acute lung acute respiratory distress. OBJECTIVE To shed a light on the likely benefits of the oral phosphodiesterase 5 (PDE5) inhibitor adjuvant role in combating COVID-19 infection. METHODS A literature review was performed in the PubMed/Medline database, Scopus, Cochrane Library, EMBASE, Academic Search Complete, Google Scholar, and CINAHL databases using the keywords COVID-19; phosphodiesterase-5 inhibitors; cytokine storm; respiratory distress. RESULTS Despite the worsening trends of COVID-19, still no drugs are validated to have significant clinical efficacy in the treatment of patients with COVID-19 in large-scale studies. While the progress toward a curative agent and/or vaccine is certainly hopeful, the principal limiting factor in such public health emergencies is always the time. Therefore, a preexisting licensed therapeutic(s) might offer a reprieve to the healthcare systems operating at the edge of capacity. In this context, the innovation of oral PDE5 inhibitors with their valuable effects on erection have provided a breakthrough in the treatment of erectile dysfunction and opened new fields of clinical application for this class of drugs. Oral PDE5 inhibitors have been demonstrated to possess many beneficial useful additional implications with acknowledged anti-inflammatory, antioxidant, immune response regulation, and antiapoptotic properties. These properties have been elucidated through the nitric oxide/soluble guanylyl cyclase/cyclic guanylate monophosphate pathway in addition to the emerged hemeoxygenase-1 enzyme as well as hydrogen sulfide pathways. These properties could support repurposing oral PDE5 inhibitors' potential adjuvant use in targeting different aspects of COVID-19 infection. CONCLUSION Oral PDE5 inhibitors retain several acknowledged off-labeled useful implications with anti-inflammatory, antioxidant, immune response regulation, and antiapoptotic properties. These properties may support repurposing oral PDE5 inhibitors' potential adjuvant use in the protocols combating COVID-19 manifestations. Mostafa T.

[PMID: 33301232 PMCID: PMC7883102 DOI: 10.1111/dth.14662] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Revised: 12/05/2020] [Accepted: 12/07/2020] [Indexed: 12/22/2022]
Abstract
Most of drugs could have certain mucocutaneous reactions and COVID-19 drugs are not an exception that we focused. We systematically reviewed databases until August 15, 2020 and among initial 851 articles, 30 articles entered this study (20 case reports, 4 cohorts, and 6 controlled clinical trials). The types of reactions included AGEP, morbiliform drug eruptions, vasculitis, DRESS syndrome, urticarial vasculitis, and so on. The treatments have been used before side effects occur, included: antimalarial, anti-viral, antibiotics, tocilizumab, enoxaparin and and so on. In pandemic, we found 0.004% to 4.15% of definite drug-induced mucocutaneous reactions. The interval between drug usage and the eruption varied about few hours to 1 month; tightly dependent to the type of drug and hydroxychloroqine seems to be the drug with highest mean interval. Antivirals, antimalarials, azithromycin, and tocilizumab are most responsive drugs for adverse drug reactions, but antivirals especially in combination with antimalarial drugs are in the first step. Types of skin reactions are usually morbilliform/exanthematous maculopapular rashes or urticarial eruptions, which mostly may manage by steroids during few days. In the setting of HCQ, specific reactions like AGEP should be considered. Lopinavir/ritonavir is the most prevalent used drug among antivirals with the highest skin adverse reaction; ribarivin and remdisivir also could induce cutaneous drug reactions but favipiravir has no or less adverse effects. Logically the rate of dermatologic adverse effects among anivirals may relate to their frequency of usage. Rarely, potentially life-threatening reactions may occur. Better management strategies could achieve by knowing more about drug-induced mucocutaneous presentations of COVID-19.

A comprehensive review study. JOURNAL OF RESEARCH IN MEDICAL SCIENCES : THE OFFICIAL JOURNAL OF ISFAHAN UNIVERSITY OF MEDICAL SCIENCES 2020; 25:109. [PMID: 33824674 PMCID: PMC8019127 DOI: 10.4103/jrms.jrms_777_20] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 08/11/2020] [Accepted: 09/25/2020] [Indexed: 01/08/2023]
Abstract
BACKGROUND Coronaviruses are major pathogens of respiratory system causing different disorders, including the common cold, Middle East respiratory syndrome, and severe acute respiratory syndrome. Today's global pandemic coronavirus disease 2019 (COVID-19) has high mortality rate, with an approximate of 20% in some studies, and is 30-60 times more fatal than the common annual influenza, However, there is still no gold standard treatment for it. N-acetylcysteine (NAC) is a well-known multi-potential drug with hypothetically probable acceptable effect on COVID-related consequences, which we completely focused in this comprehensive review. MATERIALS AND METHODS PubMed, Scopus, Science Direct, and Google Scholar have been searched. Study eligibility criteria: efficacy of NAC in various subclasses of pathogenic events which may occur during COVID-19 infection. Efficacy of NAC for managing inflammatory or any symptoms similar to symptoms of COVID-19 was reviewed and symptom improvements were assessed. RESULTS Randomized clinical trials introduced NAC as an antioxidant glutathione analog and detoxifying agent promoted for different medical conditions and pulmonary disorders to alleviate influenza and reduce mortality by 50% in influenza-infected animals. The beneficial effects of NAC on viral disorders, including Epstein-Barr virus, HIV and hepatitis, and well-known vital organ damages were also exist and reported. CONCLUSION We classified the probable effects of NAC as oxidative-regulatory and apoptotic-regulatory roles, antiviral activities, anti-inflammatory roles, preventive and therapeutic roles in lung disorders and better oxygenation functions, supportive roles in intensive care unit admitted patients and in sepsis, positive role in other comorbidities and nonpulmonary end-organ damages or failures and even in primary COVID-associated cutaneous manifestations. Based on different beneficial effects of NAC, it could be administered as a potential adjuvant therapy for COVID-19 considering patient status, contraindications, and possible drug-related adverse events.

Curr Pharm Des 2020; 26:4515-4521. [PMID: 32787748 DOI: 10.2174/1381612826666200811180232] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2020] [Accepted: 07/09/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND COVID-19, caused by SARS-CoV-2, is a potentially lethal, rapidly-expanding pandemic and many efforts are being carried out worldwide to understand and control the disease. COVID-19 patients may display a cytokine release syndrome, which causes severe lung inflammation, leading, in many instances, to death. OBJECTIVE This paper is intended to explore the possibilities of controlling the COVID-19-associated hyperinflammation by using licensed drugs with anti-inflammatory effects. HYPOTHESIS We have previously described that pentoxifylline alone, or in combination with oxypurinol, reduces the systemic inflammation caused by experimentally-induced pancreatitis in rats. Pentoxifylline is an inhibitor of TNF-α production and oxypurinol inhibits xanthine oxidase. TNF-α, in turn, activates other inflammatory genes such as Nos2, Icam or IL-6, which regulate migration and infiltration of neutrophils into the pulmonary interstitial tissue, causing injury to the lung parenchyma. In acute pancreatitis, the anti-inflammatory action of pentoxifylline seems to be mediated by the prevention of the rapid and presumably transient loss of PP2A activity. This may also occur in the hyperinflammatory -cytokine releasing phase- of SARS-CoV-2 infection. Therefore, it may be hypothesized that early treatment of COVID-19 patients with pentoxifylline, alone or in combination with oxypurinol, would prevent the potentially lethal acute respiratory distress syndrome. CONCLUSION Pentoxifylline and oxypurinol are licensed drugs used for diseases other than COVID-19 and, therefore, phase I clinical trials would not be necessary for the administration to SARS-CoV-2- infected people. It would be worth investigating their potential effects against the hyperinflammatory response to SARS-CoV-2 infection.

Abstract
Background: During the COVID-19 pandemic, elderly individuals (with the chronological age of 65 years and above) are more susceptible to the SARS-CoV-2 infection complications due to altered immune system response and the higher rate of underlying comorbidities. A vast majority of mortalities are reported in elderly patients; thus, this study aimed to evaluate complications of COVID-19 in elderly patients. Methods: A systematic review was conducted according to MOOSE guidelines. Science Direct, Google Scholar, Scopus, PubMed databases were searched for published articles related to COVID-19 in the elderly up to March 26, 2020. Search MeSh terms included "Severe acute respiratory syndrome coronavirus 2", "2019-nCoV", "SARS-CoV-2", "comorbidity", "elderly", and "geriatrics". Results: In total 1360 potentially relevant articles were screened, of which 35 were relevant and their full texts were considered for the review. Organ damages to the pulmonary system, cardiovascular, liver, and renal system are more prevalent in the elderly with SARS-CoV-2 infection. As the chance of multiorgan involvement is more common among elderly patients, preventive, multidisciplinary, and holistic evaluations are essential to reduce disease consequences. Conclusion: More attention needs to be paid to elderly individuals in the quarantine. Social contact should be made and maintained through online facilities, media, and phone calls to ensure patients' mental health during this stressful situation. Also, they should be provided with enough food and medications by their families or friends. Also, providing social and volunteer services might play an important role in the mental health of those patients who have no social network.
