Fulltext Global utilization of low-dose corticosteroids in severe sepsis and septic shock: a report from the PROGRESS registry

Beale R, Janes JM, Brunkhorst FM, Dobb G, Levy MM, Martin GS, et al.

Crit Care, 2010;14(3):R102.
PMID: 20525247 DOI: 10.1186/cc9044

INTRODUCTION: The benefits and use of low-dose corticosteroids (LDCs) in severe sepsis and septic shock remain controversial. Surviving sepsis campaign guidelines suggest LDC use for septic shock patients poorly responsive to fluid resuscitation and vasopressor therapy. Their use is suspected to be wide-spread, but paucity of data regarding global practice exists. The purpose of this study was to compare baseline characteristics and clinical outcomes of patients treated or not treated with LDC from the international PROGRESS (PROmoting Global Research Excellence in Severe Sepsis) cohort study of severe sepsis.
METHODS: Patients enrolled in the PROGRESS registry were evaluated for use of vasopressor and LDC (equivalent or lesser potency to hydrocortisone 50 mg six-hourly plus 50 microg 9-alpha-fludrocortisone) for treatment of severe sepsis at any time in intensive care units (ICUs). Baseline characteristics and hospital mortality were analyzed, and logistic regression techniques used to develop propensity score and outcome models adjusted for baseline imbalances between groups.
RESULTS: A total of 8,968 patients with severe sepsis and sufficient data for analysis were studied. A total of 79.8% (7,160/8,968) of patients received vasopressors, and 34.0% (3,051/8,968) of patients received LDC. Regional use of LDC was highest in Europe (51.1%) and lowest in Asia (21.6%). Country use was highest in Brazil (62.9%) and lowest in Malaysia (9.0%). A total of 14.2% of patients on LDC were not receiving any vasopressor therapy. LDC patients were older, had more co-morbidities and higher disease severity scores. Patients receiving LDC spent longer in ICU than patients who did not (median of 12 versus 8 days; P <0.001). Overall hospital mortality rates were greater in the LDC than in the non-LDC group (58.0% versus 43.0%; P <0.001). After adjusting for baseline imbalances, in all mortality models (with vasopressor use), a consistent association remained between LDC and hospital mortality (odds ratios varying from 1.30 to 1.47).
CONCLUSIONS: Widespread use of LDC for the treatment of severe sepsis with significant regional and country variation exists. In this study, 14.2% of patients received LDC despite the absence of evidence of shock. Hospital mortality was higher in the LDC group and remained higher after adjustment for key determinates of mortality.

Eight cases of liver failure and encephalopathy were observed among twenty cases of grade 3 and grade 4 dengue hemorrhagic fever/dengue shock syndrome admitted to the Department of Pediatrics, University Hospital, Kuala Lumpur from January 1990 to December 1991. All patients with deterioriation in mental status showed a marked increase in liver enzymes (aspartate and alanine aminotransaminases) and severe coagulopathy. Six patients needed cerebral protection, including ventilation, intravenous sedation and muscle relaxants. There was one death during the period of study and one case of residual hemiparesis in a boy who had, in addition, intracerebral hemorrhage. All other survivors had complete recovery of liver and neurological function.

Introduction: Training of all health personnel involved in paediatric care is a key determinant of successful outcome during paediatric emergencies. We aimed to identify the need for paediatric Mock Code Blue skills training among non-paediatricians in a pre-hospital setting through checklist assessment of their performance. Methods: A paediatric septic shock and cardiac arrest Mock Code Blue pre-hospital scenarios were presented for non-paediatricians during a National Clinical Skills Conference. Eight medical student assessors and four clinical facilitators were involved in this training. Participants were expected to be able to demonstrate the skills and teamwork necessary to managepaediatric emergencies according to the learning outcomes. Results: A total of 97 delegates participated in a facilitated paediatric Mock Code Blue for multidisciplinary groups of health personnel. Outcome measures showed a significant lack of communication and team work skills, and weakness in “closing the loop” as barriers to successful resuscitation. Conclusion: We recommend Mock Code Blue simulation training to be offered regularly to all groups of healthcare providers involved in paediatric and neonatal care while not overlooking the emphasis on non-technical skills.

Fulltext A glimpse on the function of chitosan as a dental hemostatic agent

Lestari W, Yusry WNAW, Haris MS, Jaswir I, Idrus E

Managing a bleeding patient can be a challenge during dental surgery. Profuse hemorrhage due to platelet defects, coagulation disorders, vascular anomalies, medication-induced patients, as well as inherited bleeding ailments result in soft tissue hematoma, septic shock, compromised airway, and in some severe cases, death could occur. A vast array of surgical hemostatic agents are available to stop bleeding, including chitosan-based hemostatic agents. Chitosan has an advantage over other topical hemostatic materials for its ability to promote shorter bleeding times and assist in healing. Massive behind-the-scene research and development efforts are ongoing to increase the performance of chitosan as a hemostatic agent. Numerous studies on chitosan use in dental hemostasis have registered it as being safe, biodegradable, biocompatible, promoting healing, antimicrobial and bioactive. This article reviews the application of chitosan in managing hemostasis in dental patients.

MyJurnal

Necrotising fasciitis caused by Community-Acquired Methicillin-resistant Staphylococcus aureus (CA-MRSA) has emerged as a new entity. Although it is recognised worldwide, there have been no reported cases to date in Malaysia. We report a case of necrotising fasciitis of the left lower limb in an otherwise healthy 20-year-old man. He presented with septic shock and despite the paucity of clinical signs in the limb, the infection was aggressive. Methicillin-Resistant Staphylococcus aureus (MRSA) was isolated from the deep fascia of the leg. Panton-Valentine leucocidin gene (PVL), which is a stable genetic marker for CA-MRSA strain, was positive in this case. This case of community acquired MRSA necrotising fasciitis is of concern and may herald the emergence of this resistant organism in Malaysia. Vigilant surveillance and microbiological monitoring is needed to follow this CA-MRSA trend.

Sepsis causes high mortality and morbidity. Static lactate concentration and early lactate clearance are cited to be a predictor for sepsis survival. This study examined the clinical utility of static lactate concentration and early lactate clearance within the first six hours of admission in Emergency Department (ED) to predict 28-day mortality rate in sepsis patients. Patients who presented with sepsis, severe sepsis or septic shock and admitted to ED of Universiti Kebangsaan Malaysia Medical Centre were recruited. Blood lactate concentrations were measured upon admission (H0), at 1st hour (H1) and 6th hour (H6), respectively. Either standard treatment of sepsis or early goal directed therapy was initiated according to sepsis severity. A follow-up report was conducted at 28 days via telephone call, e-mail or case notes. Patients were later classified into survivor and non-survivor as final outcome. Static lactate concentration appeared to be significantly higher for non-survivor as compared to the survival group at H0, H1 and H6 (p

Fulltext Determinants of functional status among survivors of severe sepsis and septic shock: One-year follow-up

Al Khalaf MS, Al Ehnidi FH, Al-Dorzi HM, Tamim HM, Abd-Aziz N, Tangiisuran B, et al.

Ann Thorac Med, 2015 Apr-Jun;10(2):132-6.

RATIONALE: Sepsis is a leading cause of intensive care unit (ICU) admissions worldwide and a major cause of morbidity and mortality. Limited data exist regarding the outcomes and functional status among survivors of severe sepsis and septic shock.
OBJECTIVES: This study aimed to determine the functional status among survivors of severe sepsis and septic shock a year after hospital discharge.
METHODS: Adult patients admitted between April 2007 and March 2010 to the medical-surgical ICU of a tertiary hospital in Saudi Arabia, were included in this study. The ICU database was investigated for patients with a diagnosis of severe sepsis or septic shock. Survival status was determined based on hospital discharge. Patients who required re-admission, stayed in ICU for less than 24 hours, had incomplete data were all excluded. Survivors were interviewed through phone calls to determine their functional status one-year post-hospital discharge using Karnofsky performance status scale.
RESULTS: A total of 209 patients met the eligibility criteria. We found that 38 (18.1%) patients had severe disability before admission, whereas 109 (52.2%) patients were with severe disability or died one-year post-hospital discharge. Only one-third of the survivors had good functional status one-year post-discharge (no/mild disability). After adjustment of baseline variables, age [adjusted odds ratio (aOR) = 1.03, 95% confidence interval (CI) = 1.01-1.04] and pre-sepsis functional status of severe disability (aOR = 50.9, 95% CI = 6.82-379.3) were found to be independent predictors of functional status of severe disability one-year post-hospital discharge among survivors.
CONCLUSIONS: We found that only one-third of the survivors of severe sepsis and septic shock had good functional status one-year post-discharge (no/mild disability). Age and pre-sepsis severe disability were the factors that highly predicted the level of functional status one-year post-hospital discharge.

PMID: 16211138

Melioidosis is much less common in children than in adults. This study investigated the incidence, demographic characteristics, presenting symptoms and outcome of pediatric melioidosis in Pahang, Malaysia. This retrospective study included patients < or =18 years old with positive body fluid cultures for Burkholderia pseudomallei from January 2000 to June 2003. Data on culture results were obtained from 2 referral hospitals. The incidence of pediatric melioidosis was 0.68/100,000 population per year. Of the 13 patients identified during the study period, 10 were male; 9 were Malays, 2 were Indians and 2 were aborigines. The mean age of these patients was 9.5 +/- 5.4 years. None of the patients had a previous history of confirmed melioidosis or predisposing factors for infection. Localized melioidosis was the most common presentation (46.2%) followed by melioidosis with septic shock (38.4%). Among patients with localized melioidosis, head and neck involvement (83.3%) was the most common presentation (2 patients with cervical abscesses, 1 with submandibular abscesses and 2 with acute suppurative parotitis) and another patient had right axillary abscess. All of the patients with septic shock had pneumonia and 2 of them had multi-organ involvement. The mortality among patients with septic shock was 80% and death occurred within 24 h of admission in all cases. In contrast, no complications or death occurred among patients with localized melioidosis. Melioidosis with septic shock is less common than localized melioidosis in pediatric patients, but is associated with very high mortality.

Necrotizing fasciitis (NF) is a deadly soft tissue infection causing a significant morbidity and mortality. Abdominal and chest wall NF are unusual. We describe a 49-year-old male with anterior abdominal wall NF secondary to per- forated gastric ulcer (PGU). He was admitted in septic shock presenting an abdominal wall NF with severe metabolic acidosis requiring dialysis and admission to the intensive care unit. There was a patch of gangrene with surrounding skin discoloration at lower quadrant of the abdominal wall. Local debridement was done without a preoperative computed tomography that was performed after surgery. Adequate source control was not achieved after the second surgery and the patient had worsened resulting to death. We describe this rare presentation of NF and discuss the issues learnt from this unfortunate event.

We present a case study of a 26-year-old morbidly obese man with a three-day history of right leg pain and swelling. The swelling was associated with low grade fever. He was alert and conscious upon presentation to the hospital. His physical examination showed gross swelling of the entire right lower limb with no systemic manifestations. There was no discharge and bullae from the swelling area of the leg. He had high blood sugar and was newly diagnosed with type 2 diabetes mellitus. He was diagnosed with necrotizing fasciitis. An intravenous imipenem-cilastatin 500 mg every 6 h together with clindamycin 900 mg every 8 h was started empirically. Extensive wound debridement was performed. The swab culture obtained intraoperatively grew Pseudomonas aeruginosa. He required an above knee amputation due to worsening infection despite wound debridement. Post-operatively, he developed acute kidney injury with severe metabolic acidosis, which required daily hemodialysis. However, the patient deteriorated due to septic shock with multi-organ failure, resulting in his death.

MyJurnal

Strongyloides stercoralis is an intestinal nematode which is endemic in tropical and subtropical countries. The global prevalence of Strongyloides is unknown. Strongyloidiasis is found more frequently in the socioeconomically disadvantaged, in institutionalized populations, and in rural areas. The spectrum of disease varies. It may cause asymptomatic infection, mild eosinophilia or hyperinfection syndrome in the most severe form. Here we reported a case of Strongyloides hyperinfection syndrome in an immunosuppressed patient. This patient is a 54-year-old man with myasthenia gravis on long term azathioprine and prednisolone. He presented with fever associated with diarrhoea and was in septic shock. His blood culture was positive forKlebsiella pneumoniae.Strongyloides stercoralis larvae were detected in his sputum and stool sample. He was diagnosed to have Strongyloides hyperinfection and was treated with subcutaneous ivermectin. He recovered well. Our case demonstrated the association of Strongyloideshyperinfection with superimposed gram-negative sepsis as a consequence of prolonged immunosuppression. A high index of suspicion is needed in approaching patient with risk factors of hyperinfection syndrome.

Third-generation cephalosporin resistant Enterobacteriaceae (TCRE) is a global concern especially in neonatal sepsis. We performed a secondary data analysis in a Thai neonatal intensive care unit to identify the risk factors for acquisition of TCRE sepsis and mortality of Enterobacteriaceae sepsis between 1991 and 2017. Multivariate logistic and Cox proportional regression were used for analysis. Numbers of neonates with TCRE and nonTCRE sepsis were 100 and 41 patients, respectively. Medians (interquartile ranges) of gestational age, birthweight, onset of sepsis and total hospital stay of neonates with Enterobacteriaceae sepsis were 32 (28, 38) weeks, 1670 (1025, 2750) grams, 11 (6, 25) days and 41 (22, 74) days, respectively. Univariate and multivariate analysis, neonates with TCRE sepsis were more likely to have birth asphyxia (adjusted odds ratio [aOR] = 2.6; 95% confidence interval [CI] 1.1-6.0; p = 0.02) and history of aminoglycoside exposure (aOR = 2.9; 95% CI 1.3- 6.7; p = 0.01). In-hospital case fatality rate from Enterobacteriaceae sepsis was 26% (36/141). In Cox regression, neonates with TCRE sepsis was not an independent risk of non-survivors, but septic shock (adjusted hazard ratio = 9.9; 95% CI 5.0-19.7, p < 0.001) increased 30-day mortality in the final model. Asphyxia and previous aminoglycoside consumption were risks of acquisition for neonatal TCRE sepsis while the burden was not a significant difference. Infection prevention and control must be strictly implemented in high multidrug-resistant area.

PMID: 28725564 DOI: 10.1016/j.idcr.2017.05.002

We report a fatal case of post-partum streptococcal toxic shock syndrome in a patient who was previously healthy and had presented to the emergency department with an extensive blistering ecchymotic lesions over her right buttock and thigh associated with severe pain. The pregnancy had been uncomplicated, and the mode of delivery had been spontaneous vaginal delivery with an episiotomy. She was found to have septicemic shock requiring high inotropic support. Subsequently, she was treated for necrotizing fasciitis, complicated by septicemic shock and multiple organ failures. A consensus was reached for extensive wound debridement to remove the source of infection; however, this approach was abandoned due to the patient's hemodynamic instability and the extremely high risks of surgery. Both the high vaginal swab and blister fluid culture revealed Group A beta hemolytic streptococcus infection. Intravenous carbapenem in combination with clindamycin was given. Other strategies attempted for streptococcal toxic removal included continuous veno-venous hemofiltration and administration of intravenous immunoglobulin. Unfortunately, the patient's condition worsened, and she succumbed to death on day 7 of hospitalization.

MyJurnal

Enterobacter gergoviae is a gram negative rod-shaped opportunistic organism reported to cause urinary and respiratory tract infections, but peritonitis caused by this organism is unknown. We report a case of 50-year-old patient on peritoneal dialysis (PD) presented with Enterobacter gergoviae peritonitis with septic shock. Despite Intraperitoneal (IP) cloxacillin 250mg qid and IP ceftazidime 1gram q24h and subsequent escalation with IP amikacin 2mg/kg q24h and IP vancomycin 15mg/kg q24h within the next 48 hours, his peritonitis remained refractory and required catheter removal. Although Enterobacter gergoviae is naturally sensitive to aminoglycosides, carbapenems and quinolones, it reacts differently to the beta lactam antibiotics. Their resistance to third-generation cephalosporins is fast emerging and treatment with third-generation cephalosporins may cause AmpC-overproducing mutants. The majority of
Enterobacteriaceae, including Extended-spectrum beta-lactamases producers, remain susceptible to carbapenems. Our report provides an unfavourable course of E. gergoviae peritonitis likely due to acquired secondary drug resistance during the therapy period.

Fulltext Clinical Manifestations and Risk Factors of Streptococcus suis Mortality Among Northern Thai Population: Retrospective 13-Year Cohort Study

Rayanakorn A, Katip W, Goh BH, Oberdorfer P, Lee LH

Infect Drug Resist, 2019;12:3955-3965.
PMID: 32021313 DOI: 10.2147/IDR.S233326

Purpose: Streptococcus suis (S. suis) is an emerging zoonotic disease mainly in pigs, causing serious infections in humans with high prevalence in Southeast Asia. Despite a relatively high mortality rate, there are limited data regarding the risk factors of this life-threatening infection. Therefore, a 13-year retrospective cohort study in Chiang Mai, Thailand during 2005-2018 was conducted to explore risk factors associated with S. suis mortality and to update the outcomes of the disease.
Patients and methods: S. suis positive cases were derived from those with positive S. suis isolates from microbiological culture results and Matrix-Assisted Laser Desorption Ionization Time of Flight (MALDI-TOF). Potential risk factors of mortality were identified using univariate and multivariate logistic regression.
Results: Of 133 patients with culture-proven S. suis infection identified, there were 92 males and 41 females. The mean age was 56.47 years. Septicemia (55.64%) was the most common clinical manifestation followed by meningitis (37.59%) and infective endocarditis (25.56%). Alcohol drinking and raw pork consumption were documented in 66 (49.62%) and 49 (36.84%) cases respectively. The overall mortality rate was 12.03% (n=16). According to the multivariate analysis, the independent risk factors for mortality were prolonged bacteremia ≥ 6 days (OR = 43.57, 95% CI = 2.46-772.80, P =0.010), septic shock (OR = 13.34, 95% CI = 1.63-109.03, P =0.016), and direct bilirubin > 1.5 mg/dL (OR = 12.86, 95% CI = 1.91-86.59, P =0.009).
Conclusion: S. suis is not infrequent in Northern Thailand, where the cultural food habit of raw pork eating is still practiced. To the best of our knowledge, this is the largest series focusing on risk factors of S. suis mortality which has been conducted in Thailand. Prolonged bacteremia ≥ 6 days, septic shock, and direct bilirubin > 1.5 mg/dL were strong predictors associated with S. suis mortality. The mortality risk factors identified may be further utilized in clinical practice and future research to improve patient outcomes.
