RESUMEN

BACKGROUND: Coagulation disorders are frequently encountered among patients infected with coronavirus disease 2019 (COVID-19), especially among admitted patients with more severe symptoms. This study aims to determine the mortality rate and incidence and risk factors for venous thromboembolism (VTE) in hospitalized patients with COVID-19. METHODS: This retrospective observational cohort study was conducted from March to July 2020 using a hospital database. All adult patients (>18 years old) with laboratory-confirmed COVID-19 were included. Laboratory data and the real-time reverse transcriptase-polymerase chain reaction (rRT-PCR) for SARS-CoV-2 were obtained from medical records. The mortality rate and the incidence of VTE were established as study results. A multivariate logistic regression analysis was performed to identify predictors of thrombotic events. RESULTS: rA total of 1024 confirmed COVID-19 patients were treated, of whom 110 (10.7%) were deceased and 58 patients (5.7%) developed VTE. Death occurred more frequently in patients older than 50 years and those admitted to the intensive care unit (ICU, 95%) and who received mechanical ventilation (62.7%). Multivariate analysis revealed that cancer patients were two times more likely to have VTE (adjusted odds ratio = 2.614; 95% CI = (1.048-6.519); p = 0.039). Other chronic diseases, such as diabetes, hypertension, and chronic kidney disease, were not associated with an increased risk of VTE. CONCLUSIONS: One-tenth of hospitalized COVID-19 patients were deceased, and VTE was prevalent among patients with chronic conditions, such as cancer, despite anticoagulation therapy. Healthcare professionals should closely monitor individuals with a high risk of developing VTE to prevent unwanted complications.

RESUMEN

Background: Olfactory and gustatory dysfunctions are frequently reported symptoms among COVID-19 patients. However, several reports suggested that there might be significant variation in the prevalence and clinical picture of chemosensory dysfunction in COVID-19 patients among different population. Objective: To study the prevalence of chemosensory dysfunction, recovery time and its impact on quality of life (QoL) among COVID-19 patients in Saudi population. Methods: This multi-centre observational study was conducted at three COVID-19 centres in Saudi Arabia. Epidemiological and clinical data were extracted at baseline and within the 2-month post-infection. Olfactory and gustatory dysfunctions were assessed via valid taste and smell questionnaire, electronically collected via online survey. Short version of questionnaire of Olfactory disorders-negative statements (sQOD-NS) was used to assess the impact on QoL. Result: Total 1734 patients [926 males and 808 females, the mean age of patients was 37.7±11.6 years] with laboratory confirmed COVID-19 were recruited for this study. Chemosensory dysfunction was reported in 56.5% cases. olfactory and gustatory dysfunctions were significantly high in females (66.2%) and age group younger than or equal to 40 years (62.2%). Among patients with olfactory dysfunction and gustatory dysfunction, recovery rate was 757 (77.2%) and 702 (71.6%). Furthermore, the recovery time was within 8 days of onset of symptoms in 53.6% and 61.3% of olfactory dysfunction and gustatory dysfunction cases, respectively. Overall mean QoL score indicated Olfactory and gustatory dysfunction has significant impact on QoL [11.3±6.2 (P value<0.001)]. female as compared to males (12.8±7). Females had significant impact on QoL (11.4±6.6) as compared to males [12.8±7 (P value<0.001)]. Conclusion: Chemosensory dysfunction among Saudi population was comparable to the European data and significantly higher than Asian supporting the fact that these symptoms vary as per ethnicity. Olfactory and gustatory dysfunction significantly impaired QoL and could present as an early symptom of COVID-19. Recovery rate of these symptoms can serve as a good prognostic data for patient's counselling. Further long-term follow-up studies would lead to better understanding of prognosis and clinical outcomes.

RESUMEN

Background and aim: Hepatitis C virus (HCV) infection is a major global public health concern, being a leading cause of chronic liver diseases such as chronic hepatitis, cirrhosis, and hepatocellular carcinoma. The virus is classified into 8 genotypes and 93 subtypes, each displaying distinct geographic distributions. Genotype 4 is the most predominant in the Middle East and Eastern Mediterranean and is associated with high rates of hepatitis C infection worldwide. This study used next-generation sequencing to fully characterize the HCV genome and identify a novel subtype within genotype 4 isolated from a 64-year-old Saudi man diagnosed with hepatitis C. Methods: We analyzed the complete genome of the 141-HCV isolate using whole-genome sequencing. Results: Our phylogenetic reconstructions, based on the entire genome of HCV-4 strains, revealed that the 141-HCV isolate formed a distinct group within the genotype 4 classification, providing valuable new insights into the variability of HCV. Conclusion: This discovery of a previously unclassified HCV subtype within genotype 4 sheds light on the ongoing evolution and diversity of the virus. Such knowledge has significant implications for diagnostic and therapeutic approaches, as different subtypes may exhibit varying drug sensitivities and resistance profiles.

RESUMEN

Rhodococcus equi is a Gram-positive coccobacillus that falls within the category of aerobic actinomycetes. The Rhodococcus genus belongs to the nocardioform bacteria group. This microorganism has been found in various settings, including natural environments, animals, and particularly in individuals with compromised immune systems, such as those living with HIV. Notably, there is an increasing number of reports concerning R. equi infections in transplant recipients and even individuals with a normally functioning immune system. Traditionally, R. equi has been primarily associated with pulmonary infections, but there is a growing body of evidence documenting its involvement in extrapulmonary infections. In this report, we present a case involving a newly diagnosed HIV patient who experienced R. equi -induced necrotizing pneumonia, bacteremia, and a brain abscess in newly diagnosed HIV patient. It is important to note that a direct Gram stain may potentially lead to misclassification of such microorganisms as contaminants. Microbiologists should therefore prioritize the careful examination of colony morphology, biochemical reactions, and consider the limitations of automated machine databases. Furthermore, they should correlate their identification findings with clinical data to ensure optimal patient care and management, especially in the context of an immunocompromised state.

RESUMEN

BACKGROUND: Despite tremendous efforts to prevent central line-associated bloodstream infections, they still remain life-threatening complications among hospitalized patients with significant morbidity and mortality worldwide. The emerging antibiotic-resistant bacteria and other risk factors, including patient comorbidities, complicate patient management. METHODS: A single-center retrospective observational study was conducted at King Fahad Hospital of the University, Eastern Province, Saudi Arabia. Hospitalized patients with confirmed central line-associated bloodstream infections between January 2015 and December 2020 were included. The primary objectives were to investigate the trends in antibiotic susceptibility patterns of the causative agents, coexisting comorbid conditions, and other risk factors associated with mortality. RESULTS: A total of 214 patients with confirmed central line-associated bloodstream infections were included (CLABSI). The overall 30-day mortality rate was 33.6%. The infection rates per 1000 central line days for medical, surgical, and pediatric intensive care units were 4.97, 2.99, and 4.56 per 1000 CL days, respectively. The overall microbiological trends showed a predominance of Gram-negative agents, a steady increase of fungal CLABSI up to 24.0% in 2020, and a high prevalence of multidrug resistance up to 47% of bacterial CLABSI. In addition, the study indicates a significant negative surviving correlation with diabetes mellitus, cardiovascular disease, lung disease, chronic kidney disease, and the presence of ≥ 3 comorbidities (P < 0.05). CONCLUSION: The microbiological trends of the study population demonstrated a steady increase of CLABSI caused by Candida spp. with a predominance of Gram-negative pathogens. Stratifying the patients according to relevant mortality risk factors, including patient comorbidities, will help reduce CLABSI rates and improve patient outcomes.

RESUMEN

Background: The COVID-19 pandemic continues with new waves that could persist with the arrival of new SARS-CoV-2 variants. Therefore, the availability of validated and effective triage tools is the cornerstone for proper clinical management. Thus, this study aimed to assess the validity of the ISARIC-4C score as a triage tool for hospitalized COVID-19 patients in Saudi Arabia and to compare its performance with the CURB-65 score. Material and methods: This retrospective observational cohort study was conducted between March 2020 and May 2021 at KFHU, Saudi Arabia, using 542 confirmed COVID-19 patient data on the variables relevant to the application of the ISARIC-4C mortality score and the CURB-65 score. Chi-square and t-tests were employed to study the significance of the CURB-65 score and the ISARIC-4C score variables considering the ICU requirements and the mortality of COVID-19 hospitalized patients. In addition, logistic regression was used to predict the variables related to COVID-19 mortality. In addition, the diagnostic accuracy of both scores was validated by calculating sensitivities, specificities, positive predictive value, negative predictive value, and Youden's J indices (YJI). Results: ROC analysis showed an AUC value of 0.834 [95% CI; 0.800-0.865]) for the CURB-65 score and 0.809 [95% CI; 0.773-0.841]) for the ISARIC-4C score. The sensitivity for CURB-65 and ISARIC-4C is 75% and 85.71%, respectively, while the specificity was 82.31% and 62.66%, respectively. The difference between AUCs was 0.025 (95% [CI; -0.0203-0.0704], p = 0.2795). Conclusion: Study results support external validation of the ISARIC-4C score in predicting the mortality risk of hospitalized COVID-19 patients in Saudi Arabia. In addition, the CURB-65 and ISARIC-4C scores showed comparable performance with good consistent discrimination and are suitable for clinical utility as triage tools for hospitalized COVID-19 patients.

RESUMEN

The study aimed to characterize the genotype and subgenotypes of HBV circulating in Saudi Arabia, the presence of clinically relevant mutations possibly associated with resistance to antivirals or immune escape phenomena, and the possible impact of mutations in the structural characteristics of HBV polymerase. Plasma samples from 12 Saudi Arabian HBV-infected patients were analyzed using an in-house PCR method and direct sequencing. Saudi patients were infected with mainly subgenotype D1. A number of mutations in the RT gene (correlated to antiviral resistance) and within and outside the major hydrophilic region of the S gene (claimed to influence immunogenicity and be related to immune escape) were observed in almost all patients. Furthermore, the presence of mutations in the S region caused a change in the tertiary structure of the protein compared with the consensus region. Clinical manifestations of HBV infection may change dramatically as a result of viral and host factors: the study of mutations and protein-associated cofactors might define possible aspects relevant for the natural and therapeutic history of HBV infection.

RESUMEN

Background: Coronavirus disease 2019 (COVID-19) is a rapidly spreading infection that is on the rise. New variants are continuously appearing with variable degrees of lethality and infectivity. The extensive work since the start of the pandemic has led to the evolution of COVID-19 vaccines with varying mechanisms. We aim to determine real-world data by looking at the different clinical outcomes associated with COVID-19 vaccination, focusing on the rate of hospitalization, severity, and mortality. Methodology: A retrospective observational study included 624 patients with COVID-19 infection who were hospitalized at King Fahad Hospital of the University and King Fahad Military Medical City between April and July 2021. The cohort was divided into 3 groups: unvaccinated, partially vaccinated (PV), and fully vaccinated (FV). The severity and outcome of COVID-19 disease were compared among the three groups. Among the vaccinated group, we studied the effect of vaccine type on the severity and outcome of COVID-19 disease. Results: We found that 70.4% of patients with COVID-19 disease who required hospitalization were unvaccinated. Un-vaccination was a significant predictor of critical COVID-19 disease (OR 2.31; P <0.001), whereas full vaccination was associated with significantly milder disease severity (OR 0.36; P 0.01). Moreover, un-vaccination status was an independent predictor of longer hospitalization (OR 3.0; P <0.001), a higher requirement for ICU admission (OR 4.7; P <0.001), mechanical ventilation (OR 3.6; P <0.001), and death (OR 4.8; P <0.001), whereas the FV group had a lower risk of ICU admission (OR 0.49; P 0.045). Unvaccinated patients with comorbidities had worse severity and outcome of COVID-19 infection (P<0.05). Both vaccine types (Pfizer and AstraZeneca) had similar protective effects against the worst outcomes of COVID-19 disease. Conclusion: COVID-19 vaccination has been shown to be effective in reducing hospitalization, the severity of COVID-19 infection, and improving outcomes, especially in high-risk group patients. COVID-19 vaccination programs should continue to improve the outcome of such a disease.

RESUMEN

This study aimed to assess the association of obesity with the severity and outcome of COVID-19 infection. A retrospective observational study was performed from March to September 2020 in Saudi Arabia. Baseline and laboratory data were collected from the inpatient health record system. The cohort was divided into three groups based on body mass index. Following this, the severity and outcome of COVID-19 disease were analyzed between the three groups. Of the 502 COVID-19 cases included, 244 (48.5%) were obese. Obesity was significantly associated with severe (53.5%) or critical (28%) COVID-19 infection (P<0.001) and a higher need for ICU admission (35.8%, P=0.034). Multivariate analysis showed that overweight/obesity was an independent risk factor of severe (P<0.001) as well as critical COVID-19 infection (P=0.026, respectively) and a predictor of a higher risk of ICU admission (P=0.012). Class I obesity was associated with severe-critical COVID-19 disease (33.6%, P=0.042) compared to other obesity classes. Obesity is an independent risk factor for severe-critical COVID-19 infection and a higher risk of ICU admission. Clinicians should give special attention to such populations and prioritize vaccination programs to improve outcomes.

RESUMEN

OBJECTIVES: To assess the otorhinolaryngological (ORL) symptoms, including their prevalence, severity, and early presentations among coronavirus disease-19 (COVID-19) patients in the Saudi population. METHODS: This was a multicentric, cross-sectional study carried out on severe acute respiratory syndrome coronavirus-2 positive patients at 3 COVID-19 centres; Imam Abdulrahman Bin Faisal University, King Fahd Hospital of the University, ALKhobar, Qatif Central Hospital, AlQatif, and Ohud Hospital, Al Madinah Al Munawarah, Saudi Arabia. The validated survey consisted of sociodemographic data, general symptoms of COVID-19, and ORL manifestations. RESULTS: A total of 1734 COVID-19 positive patients were included in the study (mean age: 37.7±11.6 years). Most of the cases were mild (51.8%), followed by moderate (45.6%), and severe (2.6%) cases. Approximately 33.7% were asymptomatic. Severity of symptoms was significantly associated with male gender (p=0.017), higher age-group (p=0.04), and smoking (p<0.001). The most common initial ORL presentations were sore throat (20.9%), anosmia (15.5%), hyposmia (10%), and loss of taste (11.4%). Overall, 79.5% showed ORL symptoms as the initial presenting symptoms for COVID-19, with anosmia and sore throat being the most common symptoms. CONCLUSION: This study confirmed the prevalence of ORL symptoms among COVID-19 patients in Saudi Arabia. Moreover, these symptoms could also be considered for early detection of COVID-19 as they might appear prior to other symptoms.

RESUMEN

PURPOSE: This study investigated the clinical determinants of mortality in hospitalized patients infected with COVID-19. PATIENTS AND METHODS: A retrospective multicenter large cohort of COVID-19 patients hospitalized between March 2020 and February 2021. We included patients admitted with a confirmed COVID-19 infection with positive COVID-19 through real-time polymerase chain reaction (RT-PCR). SPSS version 25.0 (Armonk, NY: IBM Corp.) was used to analyze the data. RESULTS: Among the study participants (n = 1444), the mean age of the population was 49.22±17.69 years, of which 63.9% were males (n = 924). Overall, the mean age for non-survivors was 55.65 ±16.41 years and the length of ICU stay was 13.95 ±12.4 years. The most common comorbidity among the study subjects was hypertension (HTN) (32.7%), followed by cardiovascular disease (CVD) (10.7%). Patients who were mechanically ventilated (MV) had higher mortality than those who did not require MV (p < 0.001). CONCLUSION: Our study concluded that old age, the presence of underlying cardiovascular conditions, an abnormal WBC count (leukopenia or leukocytosis), and abnormal blood urea nitrogen (BUN) levels are among the independent predictors of mortality in the Saudi population. These findings may guide health care providers to manage COVID-19 patients more effectively with better outcomes.

RESUMEN

Coronavirus Disease 2019 (COVID-19) pandemic is still on-going worldwide. The available information regarding the seasonal influenza vaccine (SIV) coverage during the COVID-19 pandemic and its impact on SARS-CoV-2 spread are limited. Moreover, it is argued that SIV may or may not lessen the COVID-19 severity. No previous studies have been revealed SIV coverage among COVID-19 patients and its association with COVID-19 spread and severity, especially in Saudi Arabia. Hence, this study aimed to estimate the influenza vaccine uptake in confirmed COVID-19 patients and investigate its impact on COVID-19 spread and severity. Accordingly, 1734 COVID-19 confirmed patients were included from three government hospitals in Saudi Arabia (SA). The data were collected electronically through a newly formed, self-administrated questionnaire. Among those patients, 335 were covered with SIV (19.31%), and the coverage rate of females and males was 23.4% and 15.8%, respectively. Severe COVID-19 cases were less in vaccinated patients than in non-vaccinated (2.69% vs. 3.5%, respectively). Additionally, the results showed a significant decrease in getting infected by SARS-CoV-2 after receiving SIV (P = 0.022). Even with the tremendous efforts to promote SIV uptake among the general population and high-risk groups, the SIV coverage in SA is not optimal yet. Nevertheless, there is a significant decrease in the probability of getting infected with SARS-CoV-2 after receiving SIV. Such findings with the continuous progression of the COVID-19 pandemic call for a novel approach regarding vaccination policies to increase SIV and COVID-19 vaccine uptake.

RESUMEN

BACKGROUND Prototheca spp. are common and found in various environments, including animal and human intestines, on the skin and in respiratory tissues, and colonizing fingernails. Few strains pathogenic for humans have been discovered. Here, we describe an infection by the pathogenic fungus species Prototheca zopfii in a patient. The infection was initially classified as a fungus based on colony morphology, fungal staining results, and growth in some fungi culture media (Sabouraud dextrose agar [SDA]). Reports of Prototheca spp. infections are increasing, often with poor outcomes. The use of matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF MS) technique for identification has been widely described. Phenotypic identification depends on microscopic examination of the direct wet mount and after subculturing in blood and SDA using different stains that show a typical morphological characteristic of Prototheca spp. CASE REPORT A 48-year-old woman was diagnosed with a P. zopfii infection after 22 days of hospitalization in the critical care unit. The patient had profound febrile neutropenia and absolute neutrophil count (ANC) was zero, associated with hypotension and disseminated intravascular coagulation (DIC) 10 days after receiving the first cycle of chemotherapy for metastatic breast adenocarcinoma. Unfortunately, the patient died within 2 days of the initiation of treatment with amphotericin B. CONCLUSIONS This case report highlights algae infections as a possible opportunistic infection type in patients with profound neutropenia, and we discuss the use of MALDI-TOF MS-based technology in detecting such infections and predicting poor prognosis, especially in patients with the disseminated form with underlying febrile neutropenia.

RESUMEN

This study aimed to characterize the HCV genetic subtypes variability and the presence of natural occurring resistance-associated substitutions (RASs) in Saudi Arabia patients. A total of 17 GT patients were analyzed. Sequence analysis of NS3, NS5A, and NS5B regions was performed by direct sequencing, and phylogenetic analyses were used to determine genetic subtypes, RAS, and polymorphisms. Nine patients were infected by GT 4a, two with GT 4o and three with GT 4d. Two patients were infected with apparent recombinant virus (4a/4o/4a in NS3/NS5A/NS5B), and one patient was infected with a previously unknown, unclassifiable, virus of GT 4. Natural RASs were found in six patients (35%), including three infected by GT 4a, two by GT 4a/GT 4o/GT 4a, and one patient infected by an unknown, unclassifiable, virus of GT 4. In particular, NS3-RAS V170I was demonstrated in three patients, while NS5A-RASs (L28M, L30R, L28M + M31L) were detected in the remaining three patients. All patients were treated with sofosbuvir plus daclatasvir; three patients were lost to follow-up, whereas 14 patients completed the treatment. A sustained virological response (SVR) was obtained in all but one patient carrying NS3-RAS V170I who later relapsed. GT 4a is the most common subtype in this small cohort of Saudi Arabia patients infected with hepatitis C infection. Natural RASs were observed in about one-third of patients, but only one of them showed a treatment failure.

RESUMEN

A 69-year-old man renal transplant recipient for 4 years, presented with 4-day history of cough and dyspnoea. He was diagnosed with community-acquired pneumonia and treated accordingly. He deteriorated requiring intensive care unit admission and intubation. Mycobacterial culture from bronchoalveolar lavage grew colonies within 7 days of incubation while Mycobacterium tuberculosis PCR was negative. The antibiotic regimen was adjusted to cover for rapidly growing mycobacteria with imipenem, amikacin and clarithromycin. The final culture reported Mycobacterium cosmeticum He improved on the antibiotic regimen given which the organism turned to be sensitive to. We reported the second case with M. cosmeticum that fulfilled the diagnostic criteria for non-tuberculous mycobacterial lung infection. Improvement of patient's lung infection on appropriate antibiotics points to a causal relationship.

RESUMEN

Pseudomonas bacteria are widespread pathogens that account for considerable infections with significant morbidity and mortality, especially in hospitalized patients. The Pseudomonas genus contains a large number of species; however, the majority of infections are caused by Pseudomonas aeruginosa, infections by other Pseudomonas species are less reported. Pseudomonas stutzeri is a ubiquitous Gram-negative bacterium that has been reported as a causative agent of some infections, particularly in immunocompromised patients but has rarely been reported as a cause of infective endocarditis. Here, we report a case of a 55-year-old female with no significant medical history who presented with exertional dyspnea, productive cough, and fever. She was diagnosed as a case of acute anterior ST myocardial infarction, underwent double valve replacement surgery, and was found to have infective endocarditis caused by Pseudomonas stutzeri.

RESUMEN

BACKGROUND: Clostridioides (formerly Clostridium) difficile infection (CDI) is linked to misuse of antimicrobials. The prevalence of disease varies with difficulties of establishing the diagnosis because of the lack of sensitivity and specificity of laboratory tests. The clinical impact of upgrading CDI testing from routine to molecular based-algorithm is still unclear. The aim of this study is to assess the impact of upgrading CDI testing from routine to molecular based-algorithm on the management of CDI and evaluate the role of antimicrobials on the course of CDI. METHODS: This is an observational case-study. A total of 564 patients were included from whom stool samples were tested by enzyme immunoassay (EIA) and Xpert for C. difficile. Data on the number and results of tests ordered, antimicrobial exposure, comorbidities, and treatment with metronidazole or vancomycin were collected. The main outcome measures were C. difficile tests (EIA and Xpert C. difficile Assay) and prevalence of CDI. RESULTS: CDI was found in 9 and 10 cases out of 313 and 254 patients tested by the EIA and Xpert C. difficile assay, respectively, giving an overall incidence of 0.03 per 1,000 patient tested. Reduction was noted in the number of tests ordered per patient for presumptive CDI after shifting to the Xpert C. difficile assay which was not statistically significant (p-value 0.2). Also, there was less metronidazole and vancomycin therapy initiated for patients with a negative C. difficile test (p-value 0.2) observed with molecular testing. CONCLUSIONS: Xpert C. difficile testing is a supportive tool for diagnosing CDI with rapid turnaround time that is helpful for patient management and initiating effective infection control measures. The clinical accuracy of the assay is still to be determined in the context of low carriage rate in the local patient population.

RESUMEN

Visceral leishmaniasis is an endemic in the southwestern region of Saudi Arabia, with a low incidence rate. Clinical presentations of visceral leishmaniasis include recurrent fever, substantial weight loss, hepatosplenomegaly and anemia. However, the clinical features may not be easily evident owing to the involvement of multiple organs. This, in turn, can cause difficulties in establishing the correct diagnosis, and subsequently, in managing the patient. Here, the authors report a case of a 42-year-old male from Jizan, southwestern Saudi Arabia, who presented with impaired renal function. After kidney biopsy, the patient was diagnosed with glomerulonephritis of unknown etiology and treated with mycophenolate and prednisone.
