The existing literature is scarce on this topic, particularly in the context of Iran. The present study investigates mortality and morbidity among 62 confirmed COVID-19-associated-mucormycosis Iranian patients in relation to their demographic characteristics, laboratory test results, predisposing factors, and COVID-related factors. Material and Methods: In this prospective cohort study, the patients were identified in the fifth wave of the disease, between 1<sup>st</sup> August and 15<sup>th</sup> October 2021, with data collected at baseline with a three-week follow-up. This was a multicenter investigation with patients admitted to two clinics in Iran. 62 participants were admitted, with the key criteria of them being COVID-19-associated-mucormycosis patients. 53 out of 60 patients underwent corticosteroid therapy and debridement surgery. Intravenous remdesivir (200 mg/ kg/day at day 1, 100 mg/kg/day in following days for up to 5 days) and corticosteroids were administered for 53 out 54 patients. Oxygen therapy was only needed for 30% (n = 19) of the patients. Results: A 40% mortality rate was observed within the three-week follow-up, with deaths concentrated among those with controlled diabetes mellitus (61%) and long-term diabetes mellitus patients (an average of eight versus four years). Higher mortality was also observed in patients with higher leucocytes and those with rhino-orbital-cerebral (59%), followed by nasal (55.6%) mucormycosis. Among survivors, 32% were reinfected, and 56% suffered from loss of vision. Conclusion: The study concludes that mucormycosis is associated with a higher mortality rate among COVID-19 patients with diabetes mellitus, particularly corticosteroid recipients. Thus, urgent attention to this coinfection is warranted in Iran.展开更多

文摘In the current pandemic,COVID-19 patients with predisposing factors are at an increased risk of mucormycosis,an uncommon angioinvasive infection that is caused by fungi with Mucor genus which is mainly found in plants and soil.Mucormycosis development in COVID-19 patient is related to various factors,such as diabetes,immunocompromise and neutropenia.Excessive use of glucocorticoids for the treatment of critically ill COVID-19 patients also leads to opportunistic infections,such as pulmonary aspergillosis.COVID-19 patients with mucormycosis have a very high mortality rate.This review describes the pathogenesis and various treatment approaches for mucormycosis in COVID-19 patients,including medicinal plants,conventional therapies,adjunct and combination therapies.
文摘BACKGROUND Reports of mucormycosis,an infectious disease that commonly affects immunocompromised individuals,have increased during the ongoing coronavirus disease 2019(COVID-19) pandemic.Disseminated mucormycosis associated with COVID-19 is rare but fatal and is characterized by an aggressive clinical course and delayed diagnosis.Our report documents a case of disseminated mucormycosis after COVID-19 infection.This is a rare pathological autopsy report on COVID-19-associated mucormycosis.CASE SUMMARY A 58-year-old man was transferred to our hospital with severe COVID-19 pneumonia.During treatment for acute respiratory distress syndrome,he developed intra-abdominal bleeding that required a right hemicolectomy and ileostomy for hemostasis.The ileostoma and surgical wound developed necrosis followed by sepsis and multi-organ failure,which led to death.An autopsy revealed multiple thrombi associated with Rhizopus oryzae infection,which led to the necrosis of multiple infected organs.CONCLUSION Early suspicion and diagnosis followed by treatment are keys to better outcomes of mucormycosis in patients with severe COVID-19.

文摘BACKGROUND This study presents a case of rapidly developing respiratory failure due to antisynthetase syndrome(AS)following coronavirus disease 2019(COVID-19)in a 33-year-old man diagnosed with Klinefelter syndrome(KS).CASE SUMMARY A 33-year-old man with a diagnosis of KS was admitted to the Department of Pulmonary and Critical Care Medicine of a tertiary hospital in China for fever and shortness of breath 2 wk after the onset of COVID-19.Computed tomography of both lungs revealed diffuse multiple patchy heightened shadows in both lungs,accompanied by signs of partial bronchial inflation.Metagenomic next-generation sequencing of the bronchoalveolar lavage fluid suggested absence of pathogen.A biopsy specimen revealed organizing pneumonia with alveolar septal thickening.Additionally,extensive auto-antibody tests showed strong positivity for anti-SSA,anti-SSB,anti-Jo-1,and anti-Ro-52.Following multidisciplinary discussions,the patient received a final diagnosis of AS,leading to rapidly progressing respiratory failure.CONCLUSION This study underscores the clinical progression of AS-associated interstitial lung disease subsequent to viral infections such as COVID-19 in patients diagnosed with KS.
文摘During the outbreak of the coronavirus disease 2019(COVID-19)pandemic,particular interest rose regarding the interaction between metabolic dysfunctionassociated fatty liver disease(MAFLD)and the COVID-19 infection.Several studies highlighted the fact that individuals with MAFLD had higher probability of severe acute respiratory syndrome coronavirus 2 infection and more severe adverse clinical outcomes.One of the proposed mechanisms is the inflammatory response pathway,especially the one involving cytokines,such as interleukin 6,which appeared particularly elevated in those patients and was deemed responsible for additional insult to the already damaged liver.This should increase our vigilance in terms of early detection,close follow up and early treatment for individuals with MAFLD and COVID-19 infection.In the direction of early diagnosis,biomarkers such as cytokeratin-18 and scoring systems such as Fibrosis-4 index score are proposed.COVID-19 is a newly described entity,expected to be of concern for the years to come,and MAFLD is a condition with an ever-increasing impact.Delineating the interaction between these two entities should be brought into the focus of research.Reducing morbidity and mortality of patients with COVID-19 and MAFLD should be the ultimate objective,and the optimal way to achieve this is by designing evidence-based prevention and treatment policies.

文摘The increased risk of mucosa-associated lymphoid tissue(MALT)lymphoma is closely associated with chronic antigenic stimulation,with infection being the most common cause of recurrence.Lesions are usually associated with the gastrointestinal tract,and the involvement of small intestinal is rare.Recent studies have established a close relationship between novel coronavirus 2019(COVID-19)and the occurrence and progression of various diseases.This article presents a rare case of a small intestinal MALT lymphoma.The patient was initially admitted with COVID-19 pneumonia and subsequently developed gastrointestinal bleeding during hospitalization.Medical and endoscopic treatments were ineffective,and an emergency exploratory laparotomy was performed.The affected segment of the small intestine was excised,and a pathological biopsy confirmed the diagnosis of MALT lymphoma.This case underscores the significance of raising clinical awareness of this condition among health care professionals.
文摘BACKGROUND Metabolic dysfunction-associated steatotic liver disease(MASLD),formally known as nonalcoholic fatty liver disease,is the most common chronic liver disease in the United States.Patients with MASLD have been reported to be at a higher risk of developing severe coronavirus disease 2019(COVID-19)and death.However,most studies are single-center studies,and nationwide data in the AIM To study the influence of MASLD on COVID-19 hospitalizations during the initial phase of the pandemic.METHODS We retrospectively analyzed the 2020 National Inpatient Sample(NIS)database to identify primary COVID-19 hospitalizations based on an underlying diagnosis of MASLD.A matched comparison cohort of COVID-19 hospit-alizations without MASLD was identified from NIS after 1:N propensity score matching based on gender,race,and comorbidities,including hypertension,heart failure,diabetes,and cirrhosis.The primary outcomes included inpatient mortality,length of stay,and hospitalization costs.Secondary outcomes included the prevalence of systemic complications.RESULTS A total of 2210 hospitalizations with MASLD were matched to 2210 hospitalizations without MASLD,with a good comorbidity balance.Overall,there was a higher prevalence of severe disease with more intensive care unit admissions(9.5%vs 7.2%,P=0.007),mechanical ventilation(7.2%vs 5.7%,P=0.03),and septic shock(5.2%vs 2.7%,P<0.001)in the MASLD cohort than in the non-MASLD cohort.However,there was no difference in mortality(8.6%vs 10%,P=0.49),length of stay(5 d vs 5 d,P=0.25),and hospitalization costs(42081.5$vs 38614$,P=0.15)between the MASLD and non-MASLD cohorts.CONCLUSION The presence of MAFLD with or without liver cirrhosis was not associated with increased mortality in COVID-19 hospitalizations;however,there was an increased incidence of severe COVID-19 infection.This data(2020)predates the availability of COVID-19 vaccines,and many MASLD patients have since been vaccinated.It will be interesting to see if these trends are present in the subsequent years of the pandemic.
文摘BACKGROUND Non-alcoholic fatty liver disease(NAFLD)and metabolic-associated fatty liver disease(MAFLD)are on the rise like any other liver disease,and tend to affect 25%of the United States population.The impact of NAFLD and MAFLD on patients with coronavirus disease 2019(COVID-19)remains unclear.AIM To identify the association of NAFLD and MAFLD with mortality,hospitalization,hospital length of stay,and supplemental oxygen utilization in COVID-19 patients.METHODS A systematic review of literature on Cochrane,Embase,PubMed,ScienceDirect,and Web of Science databases was conducted from January 2019 to July 2022.Studies that evaluated NAFLD/MAFLD using laboratory methods,noninvasive imaging,or liver biopsy were included.The study protocol was registered in PROSPERO(ID CRD42022313259)and PRISMA guidelines were followed.The National Institutes of Health quality assessment tool was used to assess the quality of the studies.Pooled analysis was conducted using software Rev Man version 5.3.The stability of the results was assessed using sensitivity analysis.RESULTS Thirty-two studies with 43388 patients were included in the meta-analysis of whom 8538(20%)patients were observed to have NAFLD.There were 42254 patients from 28 studies included in the mortality analysis.A total of 2008 patients died from COVID-19;837(10.52%)in the NAFLD group and 1171(3.41%)in the non-NAFLD group.The odds ratio(OR)was 1.38 for mortality with a 95%confidence interval(95%CI)=0.97-1.95 and P=0.07.A total of 5043 patients from eight studies were included in the hospital length of stay analysis.There were 1318 patients in the NAFLD group and 3725 patients in the non-NAFLD group.A qualitative synthesis showed that the mean difference in hospital length of stay was about 2 d between the NAFLD and non-NAFLD groups with a 95%CI=0.71-3.27 and P=0.002.For hospitalization rates,the OR was 3.25 with a 95%CI of 1.73-6.10 and P=0.0002.For supplemental oxygen utilization,the OR was 2.04 with a 95%CI of 1.17-3.53 and P=0.01.CONCLUSION Our meta-analysis suggests that there are increased odds of hospitalization,longer hospital length of stay,and increased use of supplemental oxygen in NAFLD/MAFLD patients.
文摘BACKGROUND Diabetic ketoacidosis(DKA)manifests as hyperglycemia,metabolic acidosis,and ketosis.However,euglycemic DKA(eu-DKA)conceals severe DKA with glucose levels below 200 mg/dL.Sodium-glucose cotransporter-2(SGLT2)inhibitors can induce eu-DKA in diabetic patients.Notably,coronavirus disease 2019(COVID-19)-infected individuals with diabetes using SGLT2 inhibitors face an augmented risk of eu-DKA due to the direct toxic impact of the virus on pancreatic islets.This study aims to comprehensively investigate the association between SGLT2 inhibitors and eu-DKA in COVID-19 patients through meticulous case report analysis.Additionally,we endeavor to examine the outcomes and treatment approaches for COVID-19-infected diabetics receiving SGLT2 inhibitors,providing indispensable insights for healthcare professionals managing this specific patient population.AIM To investigate the connection between SGLT2 inhibitors and euglycemic DKA in COVID-19 patients through a meticulous analysis of case reports.METHODS We conducted an exhaustive search across prominent electronic databases,including PubMed,SCOPUS,Web of Science,and Google Scholar.This search encompassed the period from December 2019 to May 2022,incorporating published studies and pre-prints.The search terms employed encompassed“SGLT2 inhibitors”,“euglycemic DKA”,“COVID-19”,and related variations.By incorporating these diverse sources,our objective was to ensure a thorough exploration of the existing literature on this subject,thereby augmenting the validity and robustness of our findings.RESULTS Our search yielded a total of seven case reports and one case series,collectively comprising a cohort of twelve patients.These reports detailed instances of eu-DKA in individuals with COVID-19.Crucially,all twelve patients were utilizing SGLT2 as their primary anti-diabetic medication.Upon admission,all oral medications were promptly discontinued,and the patients were initiated on intravenous insulin therapy to effectively manage the DKA.Encouragingly,eleven patients demonstrated a favorable outcome,while regrettably,one patient succumbed to the condition.Subsequently,SGLT2 were discontinued for all patients upon their discharge from the hospital.These findings provide valuable insights into the clinical management and outcomes of eu-DKA cases associated with COVID-19 and SGLT2,underscoring the critical importance of prompt intervention and vigilant medication adjustments.CONCLUSION Our study sheds light on the possibility of diabetic patients developing both drug-related and unrelated DKA,as well as encountering adverse outcomes in the context of COVID-19,despite maintaining satisfactory glycemic control.The relationship between glycemic control and clinical outcomes in COVID-19 remains ambiguous.Consequently,this systematic review proposes that COVID-19-infected diabetic patients using SGLT2 should contemplate alternative treatment protocols until their recovery from the disease.
文摘BACKGROUND Alcohol-associated cirrhosis(AC)contributes to significant liver-related mortality in the United States.It is known to cause immune dysfunction and coagulation abnormalities.Patients with comorbid conditions like AC are at risk of worse clinical outcomes from coronavirus disease 2019(COVID-19).The specific association between AC and COVID-19 mortality remains inconclusive,given the lack of robust clinical evi-dence from prior studies.AIM To study the predictors of mortality and the outcomes of AC in patients hospitalized with COVID-19 in the United States.METHODS We conducted a retrospective cohort study using the National Inpatient Sample(NIS)database 2020.Patients were identified with primary COVID-19 hospitalizations based on an underlying diagnosis of AC.A matched comparison cohort of COVID-19 patients without AC was identified after 1:N propensity score matching based on baseline sociodemographic characteristics and Elixhauser comorbidities.Primary outcomes included median length of stay,median inpatient charges,and in-hospital mortality.Secondary outcomes included a prevalence of systemic complications.RESULTS A total of 1325 COVID-19 patients with AC were matched to 1135 patients without AC.There was no difference in median length of stay and hospital charges in COVID-19 patients with AC compared to non-AC(P>0.05).There was an increased prevalence of septic shock(5.7%vs 4.1%),ventricular fibrillation/ventricular flutter(0.4%vs 0%),atrial fibrillation(13.2%vs 8.8%),atrial flutter(8.7%vs 4.4%),first-degree atrioventricular nodal block(0.8%vs 0%),upper extremity venous thromboembolism(1.5%vs 0%),and variceal bleeding(3.8%vs 0%)in the AC cohort compared to the non-AC cohort(P<0.05).There was no difference in inpatient mortality in COVID-19 patients with non-AC compared to AC,with an odds ratio of 0.97(95%confidence interval:0.78-1.22,P=0.85).Predictors of mortality included advanced age,cardiac arrhythmias,coagulopathy,protein-calorie malnutrition,fluid and electrolyte disorders,septic shock,and upper extremity venous thromboembolism.CONCLUSION AC does not increase mortality in patients hospitalized with COVID-19.There is an increased association between inpatient complications among COVID-19 patients with AC compared to non-AC.
