COVID-19 presentations and outcome in patients with epilepsy.

OBJECTIVE: To determine whether patients with epilepsy (PWE) are particularly over-represented in a very large cohort of patients with COVID-19. We also investigated whether COVID-19 is associated with a different clinical picture or a more severe course of illness in PWE (compared with others). METHODS: All consecutive patients who referred to and admitted at healthcare facilities anywhere in Fars province (located in the south of Iran with a population of 4,851,000 people) from February 19, 2020 until November 20, 2020 were included. RESULTS: A total of 37,968 patients were studied. Eighty-two patients (0.2%) had pre-existing epilepsy. Seizures were significantly more frequent among PWE as a presenting manifestation of COVID-19 compared with that in people without epilepsy (Odds Ratio = 27; p = 0.0001). Furthermore, PWE less often reported cough (significantly) and more often had gastrointestinal symptoms (vomiting and anorexia; as trends) compared with those in people without epilepsy. Patients with epilepsy were not differently likely to be intubated or admitted at ICUs. Case fatality rates were not different between the two groups [9.8% in PWE and 8.5% in people without epilepsy; p = 0.690]. CONCLUSION: Patients with epilepsy are not susceptible to contracting COVID-19 more than other individuals. Furthermore, COVID-19 in PWE is not associated with a more severe illness or a poorer prognosis. However, PWE and COVID-19 may present somewhat differently than others with such an illness. Why PWE less often present with cough and more often present with gastrointestinal symptoms is not clear yet and should be investigated and clarified in the future studies.

A follow-up study of patients with COVID-19 presenting with seizures.

OBJECTIVE: We performed a follow-up study of patients with COVID-19 presenting with seizures. METHODS: All consecutive patients with seizures, who were referred to Namazee Hospital, Shiraz, Iran, with a diagnosis of COVID-19, from 10 August 2020 until 20 October 2020 were included in this longitudinal study. The clinical data were collected by the admitting physician. In a follow-up phone call to the discharged patients (after eight weeks or more), we inquired their seizure outcome. RESULTS: In total, 32 patients were studied; 28 patients were followed. Twelve patients (37.5%) presented with a single tonic-clonic seizure and nine (28.1%) had convulsive status epilepticus; one patient had functional (psychogenic) seizures. Ten patients (31.3%) had pre-existing epilepsy, eight others (25%) had pre-existing CNS problems (without epilepsy), one person (3.1%) had pre-existing functional seizures, and 13 individuals (40.1%) neither had epilepsy nor had other CNS problems. Eight patients (28.6%) reported experiencing seizure(s) after being discharged from the hospital; six of these had pre-existing epilepsy and one had pre-existing functional seizures. One patient, who had a newly developed ischemic brain infarction, reported experiencing recurrent seizures. CONCLUSION: Seizures in patients with COVID-19 are either acute symptomatic (in about two-thirds) or an exacerbation of a pre-existing epilepsy/functional seizures (in about one-third). A thorough investigation of the underlying etiology of seizures in patients with COVID-19 is necessary. Seizure outcome in patients, who are hospitalized with COVID-19 and seizures, is generally good.

COVID-19 in patients with Down syndrome.

PURPOSE: The aim of the current study was to determine whether COVID-19 is associated with a different presenting clinical picture or a more severe course of illness in people with Down syndrome (DS). METHODS: All consecutive patients who were admitted at healthcare facilities anywhere in Fars province (located in the south of Iran with a population of 4,851,000 people) from 19 February 2020 to 20 November 2020 were included. For every patient with DS, three age- and sex-matched patients with COVID-19 and without any underlying medical conditions were selected as controls. RESULTS: During the study period, 37,968 patients were hospitalized with a diagnosis of COVID-19. Eighteen patients had DS. Patients with DS were significantly more likely to be intubated [7 patients (39%)] compared with those without DS [3 patients (6%)]; p = 0.002. Patients with DS significantly more often died of COVID-19 compared with the controls [8 (44.4%) vs. 1 (1.9%); odds ratio: 24.37; 95% confidence interval 2.39-247.94; p = 0.007]. CONCLUSION: Patients with DS are among the high-risk populations with respect to severe COVID-19 and should receive the vaccine as soon as possible. Furthermore, they should receive more intensive care if they get hospitalized with the illness.

Survival rate in hypertensive patients with COVID-19.

INTRODUCTION: A life-threatening respiratory disease, coronavirus 2019 (COVID-19), has spread across the globe since December 2019. Many prognostic factors have already been put forward to predict the risk of death and other outcomes. The current study is evaluating the survival rate between hypertensive and non-hypertensive infected patients. METHODS: Patients who were included in this study were admitted between 20 February to 1 March 2020 in Fars (southwest of Iran) province hospitals. Data were collected from the electronic base registry which contained demographic information, medical symptoms, and signs, underlying diseases, CT scan results, and final outcome. RESULTS: Of all 1239 positive cases, 159 (12.83%) had known with hypertension ant this group was significantly older than non-hypertensive patients (66.1 years Vs 48.95 years, p < .001). According to Kaplan-Meier survival curve and log-rank test, it was seen hypertensive patients deteriorated more rapidly than non-hypertensive group (p = .032). Moreover, HIV, cardiovascular, and kidney disease were diagnosed as factors that increase the risk of death in hypertensive patients. CONCLUSION: The current study about the survival rate of COVID-19 patients had shown hypertensive patents are in danger of disease severity, although it may be related to their age. Moreover, the probability of other complications like diabetes, smoking, asthma, kidney, and cardiovascular diseases, and either some other infections such as HIV can make the condition complicated and need more consideration to prevent noxious outcomes.

Hidden threat lurking behind the alcohol sanitizers in COVID-19 outbreak.

The ongoing COVID-19 pandemic has made various challenges for communications all over the world. Nowadays hand hygiene practices with alcohol sanitizers are an unavoidable reality for many people, which cause skin dryness and flaking. The current short communication has been explained about monitoring the quality control of alcohol concentrations and hand rub formulation, which needs more attention and should consider meticulous in this crisis.

Seizure in patients with COVID-19.

OBJECTIVE: The purpose of the current study was to collect the data on the occurrence of seizures in patients with COVID-19 and to clarify the circumstances of the occurrence of seizures in these patients. METHODS: All consecutive patients who referred to healthcare facilities anywhere in Fars province (located in South Iran with a population of 4.851 million people) from February 19 until June 2, 2020, and had confirmed COVID-19 by positive result on polymerase chain reaction testing and seizure were included. RESULTS: During the study period, 6,147 people had confirmed COVID-19 in Fars province, Iran; 110 people died from the illness (case fatality rate 1.79%). During this time period, five people had seizures (seizure rate 0.08%). In four patients, seizure was one of the presenting manifestations, and in one person, it happened during the course of hospital admission. Two patients had status epilepticus. All patients experienced hypoxemia and four of them needed respirator. Two patients had related metabolic derangements and one had cerebrospinal fluid (CSF) lymphocytic pleocytosis. Brain imaging was abnormal in three patients. Four patients died. CONCLUSION: New-onset seizures in critically ill patients with COVID-19 should be considered as acute symptomatic seizures and the treating physician should try to determine the etiology of the seizure and manage the cause immediately and appropriately. Detailed clinical, neurological, imaging, and electrophysiological investigations and attempts to isolate SARS-CoV-2 from CSF may clarify the role played by this virus in causing seizures in these patients.

Which came first, the risk of migraine or the risk of asthma? A systematic review.

OBJECTIVES: We conducted this review to systematically assess the association and risk of the migraine in the patient with asthma and vice versa. METHODS: We systematically searched publishes articles indexed in PubMed, Scopus, Cochrane library, PsycINFO, CINAHL, ISI Web of Science, Science Direct from inception, and Embase databases until June 2017. The quality assessment of the involved studies was done using the Newcastle-Ottawa Scale (NOS). RESULTS: Eight studies with 389,573 participants were reviewed and selected for data extraction. Among the selected studies, 5 were reported the association between migraine with asthma risk, and the rest three studies reported the risk of asthma in patient with migraine compared to non-moraine individuals. Odds ratio (OR) of migraine for patient with asthma as compared with non-asthmatic individuals was 1.62 (95% CI 1.43-1.82). Data pooling using a random-effect model showed that migraine was associated with a significant increased risk of asthma (relative risk (RR): 1.56; 95% CI: 1.51-1.60; p < .00001). Besides, sub-group and sensitivity analyses supported the positive association between asthma and migraine, and risk of asthma in migraine patients. CONCLUSION: Now it is unknown if control of the asthma will impact the severity of migraines or vice versa, but it is necessary to perform more research to further explain the mechanisms through which asthma increases the frequency of migraine or vice versa. If two conditions linked, once an individual undergo better control of asthma symptoms, might the excruciating migraine ease, too.

Bioinformatics and Structural Analysis of Antigenic Variation in the Hemagglutinin Gene of the Influenza A(H1N1)pdm09 Virus Circulating in Shiraz (2013 to 2015).

Circulating influenza A virus provided an excellent opportunity to study the adaptation of the influenza A(H1N1)pdm09 virus to the human host. Particularly, due to the availability of sequences taken from isolates, we could monitor amino acid changes and the stability of mutations that occurred in hemagglutinin (HA). HA is crucial to viral infection because it binds to ciliated cell receptors and mediates the fusion of cells and viral membranes; because antibodies that bind to HA may block virus entry to the cell, this protein is subjected to high selective pressure. In this study, the locations of mutations in the structures of mutant HA were analyzed and the three-dimensional (3D) structures of these mutations were modeled in I-TASSER. Also, the location of these mutations was visualized and studied using Swiss PDB Viewer software and the PyMOL Molecular Graphics System. The crystal structure of the HA from A/California/07/2009 (3LZG) was used for further analysis. The new noncovalent bond formations in mutant luciferases were analyzed via WHAT IF and PIC, and protein stability was evaluated in the iStable server. We identified 33 and 23 mutations in A/Shiraz/106/2015 and A/California/07/2009 isolates, respectively; some mutations are located on the antigenic sites of Sa, Sb, Ca1, Ca2, and Cb HA1 and the fusion peptide of HA2. The results show that with the mutation some interactions are lost and new interactions are formed with other amino acids. The results of the free-energy analysis suggested that these new interactions have a destabilizing effect, which needs confirmation experimentally. IMPORTANCE Due to the fact that the mutations that occurred in the influenza virus HA cause the instability of the protein produced by the virus and antigenic changes and the escape of the virus from the immune system, the mutations that occurred in A/Shiraz/1/2013 were investigated in terms of energy level and stability. The mutations located in a globular portion of the HA are S188T, Q191H, S270P, K285Q, and P299L. On the other hand, the E374K, E46K-B, S124N-B, and I321V mutations are located in the stem portion of the HA (HA2). The change V252L mutation eliminates interactions with Ala181, Phe147, Leu151, and Trp153 and forms new interactions with Gly195, Asn264, Phe161, Met244, Tyr246, Leu165, and Trp167 which can change the stability of the HA structure. The K166Q mutation, which is located within the antigenic site Sa, causes the virus to escape from the immune response.

Death Reporting in Breakthrough and Unvaccinated SARS-CoV-2 Infection Cases.

Vaccines are undeniably an important tool for controlling infectious disease outbreaks, and they are the most certain way to end the epidemic risk. This brief report describes the characteristics of coronavirus disease 2019 (COVID-19) deaths among breakthrough and unvaccinated cases hospitalized in Fars province in the south of Iran. This cross-sectional study was performed to compare breakthrough and unvaccinated death cases in Fars, Iran (February 2, to August 19, 2021). Among 444,728 fully vaccinated people, 60,800 breakthrough cases were detected. Thus, 501 died, of which 297 (297/501) cases were hospitalized and compared with the unvaccinated dead group. The median age for breakthrough and unvaccinated cases was estimated 79 and 65 y, respectively. All signs and symptoms of COVID-19 were more frequent in the unvaccinated group. Decreasing O2 saturation (less than 93%) happened more often in the unvaccinated group significantly. Unvaccinated dead patients had significantly shorter hospital stays. These patients received 66.63% Sinopharm, 0.67% Sputnik, 0.67% COVIran Barekat, and 31.99% AstraZeneca vaccines. None of them were health-care staff. Equitable access to safe and effective vaccines is critical to ending the COVID-19 pandemic. As vaccine uptake increases, we observed a decrease in mortality and protection from severe forms of the disease.

Liver Biomarkers Assay in COVID-19 Cases: A Comparison Study between Alive and Dead Patients.

BACKGROUND: Identifying effective biomarkers plays a critical role on screening; rapid diagnosis; proper managements and therapeutic options, which is helpful in preventing serious complications. The present study aimed to compare the liver laboratory tests between alive and dead hospitalized cases for prediction and proper management of the patients. METHODS: This retrospective, cross sectional study consists of all deceased patients admitted in one center in Shiraz, Iran during 19 Feb 2020 to 22 Aug 2021. For further comparison, we selected a 1:2 ratios alive group randomly. RESULTS: Overall, 875 hospitalized cases died due to COVID-19. We selected 1750 alive group randomly. The median age was significantly higher in died group (65.96 vs 51.20). Regarding the laboratory findings during the hospitalization ALT, AST, Bili.D were significantly higher in non-survivors than survivors but Albumin was less in deceased patients. It was revealed elevated levels of Albumin, AST, Bili.T and Bili.D were associated with increasing the risk of in hospital death. Moreover, the predictive effect of ALP and Bili.D had significantly more than others with high sensitivity and specify. CONCLUSION: We found patients with COVID-19 have reduced serum albumin level, and increase ALT and AST. The current results revealed abnormal liver chemistries is associated with poor outcome, which highlighted the importance of monitoring these patients more carefully and should be given more caution.

Designing a Multicenter Registry of COVID-19 and Other Respiratory Infections in Fars, Iran.

OBJECTIVE: A year after the emergence of a novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as a new crisis in respiratory infections, there remain many uncertainties and unknowns about SARS-CoV-2 and the disease it causes, called coronavirus disease (COVID-19). Although COVID-19 is known as a respiratory disease, some atypical manifestations have been seen, different from those seen in other types of viral respiratory infections. This paper aims to describe designing, launching, and implementing a data collection system for all respiratory diseases, with a focus on SARS-CoV-2 from the onset of this pandemic. METHOD: The current registry is designed in compliance with the standard Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines, along with the declaration of Helsinki principles. RESULTS: A respiratory disease registry, with an emphasis on COVID-19 and other co-infections, was developed. Data consisted of demographic, clinical, and supporting information about SARS-CoV-2 and other respiratory viral diseases. CONCLUSION: It is hoped that the current data registry will facilitate patient evaluation and improve the outcomes of cases of respiratory infection defined by a particular condition, disease, or exposure. Moreover, the registry can harmonize data about the treatment, outcomes, and well-being of patients who receive care over time, and identify best practices.

Molecular diversity survey on diarrheagenic Escherichia coli isolates among children with gastroenteritis in Fars, Iran.

Aim: To differentiate Escherichia coli isolates from diarrheal pediatric patients in clinical laboratories. Materials & methods: Patients with watery diarrhea were selected for sampling and tested for diarrheagenic E. coli (DEC) by API kit. DEC isolates were tested for phylotyping, pathotyping and presence of determined virulence-encoding genes by specific molecular methods. Results: About 50% of isolates were detected as DECs (>55 and >31% were categorized B2 and D phylotypes respectively). Enterotoxigenic E. coli was the most and enteroinvasive E. coli was the lowest prevalent pathotypes. csg and fim genes were the most present virulence factors. Conclusion: Typing of E. coli isolates from stool specimens will help to determine the diversity of diarrheal pathogens and take proper decisions to reduce the health burden of diarrheal diseases.

The role of comorbidities on mortality of COVID-19 in patients with diabetes.

BACKGROUND: Patients with diabetes are one of the most high-risk group to become infected with SARS-CoV-2. Current study was designed to evaluate the risk of other complications in COVID-19 patients with diabetes. METHODS: In this cross-sectional study (25 February to July 10, 2020), 458 patients with diabetes were enrolled based on their characteristics, symptoms and signs, laboratory data and presence of other underlying diseases. Multiple logistic regression and Chi-square test analysis were used to check the effectiveness of other comorbidities on the mortality outcome among patients with diabetes. RESULTS: Of 458 patients with diabetes, 306 (67%) had other underlying diseases, such as 200 (65.4%) hypertension, 103 (33.7%) cardiovascular diseases and 29 (9.5%) kidney diseases. The rate of fatality was significantly high in patients with chronic kidney and liver diseases. The odds of mortality were increased 3.1-fold for patients over 55 years as compared to those under 55 years (P = 0.011), and the odds of mortality outcome were more than 5.1-fold for those who had chronic kidney disease (P < 0.001). CONCLUSIONS: The presentation of SARS-CoV-2 in older patients with diabetes with other comorbidities such as chronic kidney and liver diseases is more severe in risk of mortality.

COVID-19 in Patients With a Past History of Chemical War Injury: A Cross-Sectional Study in Southern Iran.

OBJECTIVE: This study aimed to determine whether COVID-19 is associated with a different presenting clinical picture or a more severe course of illness in people with a past history of chemical war injury. METHODS: This is a multicenter retrospective study in Fars Province, Iran, from August 22 to October 4, 2020. People with a past history of chemical war injury and COVID-19 were studied. Two age- and sex-matched control groups, double the size of the patient group each, from the same database of patients with COVID-19 who were hospitalized at the same time (ie, healthy controls and pseudocontrols). RESULTS: A total of 46 people with a past history of chemical war injury, 92 healthy controls, and 92 pseudocontrols were studied. People with COVID-19 and a past history of chemical war injury had a significantly higher rate of chest pain compared with others. There were no other clinical differences between the groups. Mortality rate was 17.39%, 15.21%, and 27.17% in people with a past history of chemical war injury, the control group, and the pseudocontrol group, respectively. CONCLUSIONS: A past history of a chemical war injury does not add to the risk of COVID-19 and does not significantly modify its clinical picture either.

Prevalence of Underlying Diseases in Hospitalized Patients with COVID-19: a Systematic Review and Meta-Analysis.

INTRODUCTION: In the beginning of 2020, an unexpected outbreak due to a new corona virus made the headlines all over the world. Exponential growth in the number of those affected makes this virus such a threat. The current meta-analysis aimed to estimate the prevalence of underlying disorders in hospitalized COVID-19 patients. METHODS: A comprehensive systematic search was performed on PubMed, Scopus, Web of science, and Google scholar, to find articles published until 15 February 2020. All relevant articles that reported clinical characteristics and epidemiological information of hospitalized COVID-19 patients were included in the analysis. RESULTS: The data of 76993 patients presented in 10 articles were included in this study. According to the meta-analysis, the pooled prevalence of hypertension, cardiovascular disease, smoking history and diabetes in people infected with SARS-CoV-2 were estimated as 16.37% (95%CI: 10.15%-23.65%), 12.11% (95%CI 4.40%-22.75%), 7.63% (95%CI 3.83%-12.43%) and 7.87% (95%CI 6.57%-9.28%), respectively. CONCLUSION: According to the findings of the present study, hypertension, cardiovascular diseases, diabetes mellitus, smoking, chronic obstructive pulmonary disease (COPD), malignancy, and chronic kidney disease were among the most prevalent underlying diseases among hospitalized COVID-19 patients, respectively.

Antibiotic resistant profile of asymptomatic bacteriuria in pregnant women: a systematic review and meta-analysis.

OBJECTIVES: Different microorganisms contribute in the pregnancy bacteriuria, which resistance microorganisms limited the therapeutic options for the treatment and increasing the related risks to pregnant women and their pregnancy. Based on this, asymptomatic bacteriuria and the use of inappropriate empirical antibiotics are dangerous in the emergence of pregnancy complications and the incidence of drug resistant. METHODS: A comprehensive systematic search was performed on all international databases including Scopus, PubMed, Web of Science, Medline, Cochrane library during 2000 - June 2019. This meta-analysis, which was registered by a pre-defined protocol in PROSPRO, carried out in accordance with PRISMA guideline. Relevant articles were included in the analysis if reported the susceptibility pattern of antimicrobial resistance related to asymptomatic bacteria in pregnant women with no acute diseases. Overall prevalence and related 95% confidence interval for resistance in different asymptomatic infections were estimated by inverse variance method. The random effect model was used in case of considerable heterogeneity. RESULTS: Results of this analysis demonstrated different resistance rate against studied classes of antibiotics. Nitrofurantoin resistance in E. coli, Klebsiella sp, P. aeruginosa, and Staphylococcus aureus isolates were estimated 0.22 (95%CI: 0.15-0.30), 0.40 (95%CI: 0.26-0.54), 0.81 (95%CI: 0.59-0.97), 0.34 (0.11-0.63), respectively. Subgroups analysis showed highest resistance in E. coli isolates, in Asia and Africa against Cefotaxime and Ampicillin, respectively. CONCLUSION: In summary, increasing resistance rate in urinary tract infection (UTI)-related agents is a risk factor that endangers both mother and fetus. Health care providers should consider screening as the radical part of infection control strategies. Due to low resistance rate to Nitrofurantoin, this drug can be a good choice for UTI treatment in pregnancies, but it should use with caution.

A Decade Epidemiological Study of Pediatric Burns in South West of Iran.

BACKGROUND: Burn is one of the most traumatic injuries and life-threatening states which expose children at a higher risk. The aim of this study was evaluating the epidemiology of pediatric burns in age less than eighteen years old during the last decade. METHODS: This cross-sectional study was carried out during 2008-2017 in Amir-al Momenin Burn Center, affiliated by Shiraz University of Medical Sciences, Shiraz, Iran. The subjects consisted of burn victims under 18 years old who were registered as outpatients and inpatients. RESULTS: During the study period, 1893 and 12431 patient were registered as inpatients and outpatients of the hospital. The burn victims were males. Children under 5 years old were prone to scald injuries more than children in any other age. More than 90% of inpatients children burned accidentally, while 116 (6.12%) burn injuries were suicidal; which was mostly seen in girls (75%, 87 out of 116). CONCLUSION: Most burns involved scalds from hot liquids especially in children age less than 5 years. Different strategies can be executed by means of broadcast flashes in mass media and educational programs through schools to show risk situation and statements calling attention to prevent childhood burn injuries.

Prevalence of underlying diseases in died cases of COVID-19: A systematic review and meta-analysis.

INTRODUCTION: Underlying disease have a critical role in vulnerability of populations for a greater morbidity and mortality when they suffer from COVID-19. The aim of current study is evaluating the prevalence of underlying disease in died people with COVID-19. METHODS: The current study have been conducted according to PRISMA guideline. International database including PubMed, Scopus, Web of Science, Cochrane and google scholar were searched for relevant studies up to 1 June. All relevant articles that reported underlying disease in died cases of COVID-19 were included in the analysis. RESULTS: After screening and excluding duplicated and irrelevant studies, 32 articles included in the analysis. The most prevalent comorbidities were hypertension, diabetes, cardiovascular disease, liver disease, lung disease, malignancy, cerebrovascular disease, COPD and asthma. Among all reported underlying disease, highest and lowest prevalence was related to hypertension and asthma which were estimated 46% (37% - 55%) and 3% (2%- 6%), respectively. CONCLUSION: In summary, underlying disease have a critical role in poor outcomes, severity of disease and high mortality rate of COVID-19 cases. Patients with hypertension, cardiovascular disease and diabetes should be carefully monitored and be aware of health protocols.

Possibility of BKV-Associated Nephropathy in Hospitalized Burn Patients.

Although renal failure in burn patients results from some defined reasons, there are various causes which are still unclear. BK virus is a human polyomavirus, which, in case of reactivation, can cause late-onset renal dysfunction and cystitis among immunodeficient patients such as transplant, pregnant, diabetic, and HIV patients. Regarding the related challenges, Polyomavirus BK (BKV), as a ubiquitous virus, is considered as one of the potential threats in the occurrence of Polyomavirus-associated nephropathy (PAN). Hypovolemia, occurring due to the weakness of the immune system, may be regarded as the major reason for the possibility of PAN as a risk factor in burn patients. Accordingly, this study was designed to evaluate the reactivation of BKV as a probable risk factor for renal failure or a problem in the future life of burn patients. This case-control study was conducted from October 2014 to September 2016, during which 270 patients were admitted to the burn unit. The patients were divided into two groups of case and control according to the inclusion criteria, and 20 patients were assigned to each group. The serum samples were first assessed for BKV-IgG and then were quantified by specific quantitative real-time polymerase chain reaction for BKV load. Positive samples were assessed for changes in noncoding regulatory region (NCRR) compared to Archetype strain by PCR sequencing method. Amplified sequences were analyzed for NCRR arrangement while the reactivation was assessed through these changes in NCRR. In both groups, patients were seropositive for BKV-IgG. Eight patients (40%) in the case group and two patients (10%) in the control group were found to be positive for BKV DNA with a load of ≥1000 and ≥100 copies/ml, respectively. There was a significant association between BKV DNA and kidney injury in the case group. The NCRR of DNA-positive samples had a large rearrangement compared to standard strain, but they showed relatively high similarity. Compared with other patients, burn patients are among the most susceptible ones to PAN, which can be considered as a major risk factor in the treatment of burn patients and optimizing their therapy.

Three Year Study of Infection Profile and Antimicrobial Resistance Pattern from Burn Patients in Southwest Iran.

INTRODUCTION: Burn wound infections, as one of the most important risk factors, cause serious complications in burns. Hence, the focus of medical care should be preventing infections and resistant isolates. The current study investigates the prevalence of infectious agents and antimicrobial resistance patterns during three years. MATERIALS AND METHODS: A total of 960 isolates were collected from different sample kinds cultured for 615 burn patients who were hospitalized during January 2016 to December 2018 in Amir-Al-Momenin Burn Center. The type of microorganism and their antibiotic resistance patterns were identified by microbiological tests and the standard disk-diffusion method according to the introduced standard techniques. RESULTS: Incidence of positive growth was seen more in males than in females. Most of the burns encountered were due to flame injuries (35.4%). Based on the diversity of bacterial isolates, Pseudomonas aeruginosa was the most frequent pathogen (49.9%), followed by Klebsiella sp. (9.7%), Acinetobacter sp. (7.2%) and Staphylococcus aureus (6.5%). The trend of resistance of meropenem was declining in P. aeruginosa isolates. Klebsiella sp. as the second most prevalent agent showed a high level of resistance to the studied antibiotics. The antibiogram results for S. aureus isolates showed an increasing trend in MRSA isolates. CONCLUSION: By evaluating the infectious agent, it was found that although frequencies of microorganisms and resistant isolates were a little high, performing a multidisciplinary approach controls the trend during the study period. These achievements have been gained due to a strict politicized infection control and stewardship program in the appointed burn center.
