Not every skin rash in a returning adult male traveler is monkeypox
No full textIn May 2022, several European countries including Spain reported cluster of monkeypox cases with no apparent travel to endemic areas. We report a suspected case of monkeypox in Saudi Arabia in a healthy 30-year-old man who returned from Spain and the Netherlands with fever and rash for six days duration during the same time period of the outbreak, he was suspected to have monkeypox but was ultimately diagnosed with chickenpox
Epidemiology and clinical characteristics of Morganella morganii infections: A multicenter retrospective study
No full textBackground: Morganella morganii is a Gram-negative, opportunistic pathogen that can cause a variety of infections, including bloodstream infections, especially in those with compromised immune systems. It is often resistant to antibiotics, making it a difficult organism to treat. Limited studies have addressed M. morganii, but the organism is becoming increasingly recognized as a public health threat. More research is needed to understand the epidemiology and virulence factors of M. morganii in Saudi Arabia, as well as to develop effective treatment strategies. Methods: This retrospective study included all M. morganii bloodstream infections patients admitted to five tertiary care hospitals in Saudi Arabia between 2015 and 2022. Results: The study population included 75 patients (45 males and 30 females) between the age of 53–72 with a 54% ICU admission rate. The most comorbidities were hypertension followed by diabetes. The most common symptoms were fever, cough, shortness of breath, vomiting, and fatigue. The study also found that M. morganii was often resistant to multiple antibiotics, including ciprofloxacin, trimethoprim/sulfamethoxazole, gentamicin, amoxicillin, nitrofurantoin, and colistin. The most common treatment for M. morganii bacteremia was carbapenems, followed by aminoglycosides, ciprofloxacin, and colistin. Source control measures, such as surgery, line removal, drainage, and tissue removal, were also used in some cases. The study found that the in-hospital mortality rate for M. morganii bacteremia was 41%. The risk of mortality was increased in patients who were admitted to the ICU, who were older than 65 years, and who had Klebsiella pneumoniae co-infection. Conclusion: M. morganii bacteremia is a serious infection that is often resistant to antibiotics. Elderly patients and patients with comorbidities are at increased risk of mortality. Source control measures and appropriate antibiotic therapy are important for improving outcomes
Factors associated with poor outcomes among hospitalized patients with COVID-19: Experience from a MERS-CoV referral hospital
No full textBackground: Coronavirus disease 2019 (COVID-19) has resulted in millions of deaths, including more than 6000 deaths in the Kingdom of Saudi Arabia (KSA). Identifying key predictors of intensive care unit (ICU) admission and mortality among infected cases would help in identifying individuals at risk to optimize their care. We aimed to determine factors of poor outcomes in hospitalized patients with COVID-19 in a large academic hospital in Riyadh, KSA that serves as a Middle East Respiratory Syndrome coronavirus (MERS-CoV) referral center. Methods: This is a single-center retrospective cohort study of hospitalized patients between March 15 and August 31, 2020. The study was conducted at King Saud University Medical City (KSUMC). COVID-19 infection was confirmed using real-time reverse transcriptase polymerase chain reaction (RT-PCR) for SARS-COV-2. Demographic data, clinical characteristics, laboratory, radiological features, and length of hospital stay were obtained. Poor outcomes were, admission to ICU, need for invasive mechanical ventilation (IMV), and in-hospital all-cause mortality. Results: Out of 16,947 individuals tested in KSUMC, 3480 (20.5%) tested positive for SARS-CoV-2 and of those 743 patients (21%) were hospitalized. There were 62% males, 77% were younger than 65 years. Of all cases, 204 patients (28%) required ICU admission, 104 (14%) required IMV, and 117 (16%) died in hospital. In bivariate analysis, multiple factors were associated with mortality among COVID-19 patients. Further multivariate analysis revealed the following factors were associated with mortality: respiratory rate more than 24/min and systolic blood pressure 37 units/L in the first 48 h of presentation, while a RT-PCR cycle threshold (Ct) value ≤24 was a predictor for IMV. Conclusion: Variable factors were identified as predictors of different outcomes among COVID-19 patients. The only predictor of IMV was a low initial Ct values of SARS-CoV-2 PCR. The presence of tachypnea, hypotension, lymphopenia, and elevated AST in the first 48 h of presentation were independently associated with mortality. This study provides possible independent predictors of mortality and invasive mechanical ventilation. The data may be helpful in the early identification of high-risk COVID-19 patients in areas endemic with MERS-CoV
Nosocomial outbreak of the Middle East Respiratory Syndrome coronavirus: a phylogenetic, epidemiological, clinical and infection control analysis
Get PDFBackground:
Middle East Respiratory Syndrome coronavirus (MERS-CoV) continues to cause intermittent community and nosocomial outbreaks. Obtaining data on specific source(s) and transmission dynamics of MERS-CoV during nosocomial outbreaks has been challenging. We performed a clinical, epidemiological and phylogenetic investigation of an outbreak of MERS-CoV at a University Hospital in Riyadh, Kingdom of Saudi Arabia.
Methods:
Clinical, epidemiological and infection control data were obtained from patients and Healthcare workers (HCWs). Full genome sequencing was conducted on nucleic acid extracted directly from MERS-CoV PCR-confirmed clinical samples and phylogenetic analysis performed. Phylogenetic analysis combined with published MERS-CoV genomes was performed. HCWs compliance with infection control practices was also assessed.
Results:
Of 235 persons investigated, there were 23 laboratory confirmed MERS cases, 10 were inpatients and 13 HCWs. Eight of 10 MERS inpatients died (80% mortality). There were no deaths among HCWs. The primary index case assumed from epidemiological investigation was not substantiated phylogenetically. 17/18 of MERS cases were linked both phylogenetically and epidemiologically. One asymptomatic HCW yielded a MERS-CoV genome not directly linked to any other case in the investigation. Five HCWs with mild symptoms yielded >75% full MERS-CoV genome sequences. HCW compliance with use of gowns was 62.1%, gloves 69.7%, and masks 57.6%.
Conclusions:
Several factors and sources, including a HCW MERS-CoV ‘carrier phenomenon’, occur during nosocomial MERS-CoV outbreaks. Phylogenetic analyses of MERS-CoV linked to clinical and epidemiological information is essential for outbreak investigation. The specific role of apparently healthy HCWs in causing nosocomial outbreaks requires further definition
Serum cortisol as a predictor of major adverse outcomes in patients with COVID-19
Get PDFBackgroundSeveral biomarkers were found to predict the severity and outcome of COVID-19 infection.AimsTo determine the serum cortisol response in patients with Coronavirus Disease 2019 (COVID-19) and its correlation with disease outcomes.Methods A prospective study among confirmed COVID-19 patients aged 18 years old and above. Morning cortisol levels were measured within 24 hours of admission. Relationship between cortisol levels and outcomes (intensive care unit (ICU) admission, intubation, and death) were analysed.Results A total of 206 patients positive for COVID-19 (mean age of 53.6±15.2 years) were included in the study. Mortality was recorded in 21 (30.4 per cent) patients with cortisol levels of ≥570nmol/L, 6 (8.8 per cent) among patients with 181–569nmol/L cortisol level, and 8 (11.6 per cent) among patients with ≤180nmol/L cortisol. Patients with cortisol levels of ≥570nmol/L were more likely to be admitted to the ICU, be intubated and longer hospital stay. Serum cortisol and ferritin levels were the most significant predictors of mortality. ConclusionOn admission, the morning cortisol level was predictive of mortality, ICU admission, intubation, and length of hospital stay in patients with COVID-19 and may be listed as an independent predictor for worse outcomes of COVID-19 infection
