Fulltext Outcome of bacteraemia in patients admitted to the adult medical wards of the UKM hospital

Petrick P, Kong NC, Nordiah AJ, Cheong IK, Tamil MA

PMID: 18551939 MyJurnal

The clinical outcome of bacteraemic patients is influenced by many factors. It is vital to know one's own local hospital epidemiological data so as to provide optimal care to the affected patients. This was a prospective, observational study carried out in the said patient population over a period of four months in the year 2005. One hundred and ninety one patients presented with bacteraemia over the study period. Fifty-two (27%) of the patients died. Mechanical ventilation, inappropriate empirical antibiotic usage, Chinese ethnicity and low serum albumin levels independently affected prognosis. These factors should alert physicians to those patients who require more intensive monitoring and care.

Evaluation of the use of Bactec anaerobic blood cultures in the detection of bacteraemia and fungaemia in children

Riley PA, Parasakthi N

Malays J Pathol, 1996 Jun;18(1):31-4.
PMID: 10879222

In an attempt to reduce costs, the role of Bactec anaerobic blood culture in the detection of bacteraemia and fungaemia in children was evaluated. Results from 3167 sets of aerobic and anaerobic blood cultures from children admitted to the University Hospital, Kuala Lumpur during a one year period, were analysed. Four hundred and eight (12.9%) sets of blood cultures were positive, of which 348 sets (11.0%) from 201 patients were clinically significant. Of the 348 significant positive sets, organisms were isolated on 177 (50.9%) occasions from both aerobic and anaerobic bottles, on 136 (39.1%) occasions from the aerobic bottle only and 35 (10.0%) occasions from the anaerobic bottle only. No strict anaerobes were isolated, but clinically significant isolates recovered from the anaerobic bottle only included Klebsiella pneumoniae, Salmonella species, Enterobacter cloacae, Staphylococcus aureus, coagulase negative staphylococci, Streptococcus pneumoniae and Group B streptococcus. Patients with bacteraemia diagnosed solely by anaerobic culture were distributed evenly across the various paediatric subspecialities. When results from the anaerobic bottles were excluded, the overall isolation rate was reduced from 11% to 9.9%. Potential financial savings resulting from omission of anaerobic cultures must be balanced against the small number of bacteraemic episodes that could be missed. Undiagnosed bacteraemia may result in increased morbidity and mortality with its own attendant financial implications.

Fulltext High sPLA2-IIA level is associated with eicosanoid metabolism in patients with bacterial sepsis syndrome

Ahmad NS, Tan TL, Arifin KT, Ngah WZW, Yusof YAM

PLoS One, 2020;15(3):e0230285.
PMID: 32160261 DOI: 10.1371/journal.pone.0230285

The aim of this study was to determine the association between secretory phospholipase A2 group IIA (sPLA2-IIA) and eicosanoid pathway metabolites in patients with bacterial sepsis syndrome (BSS). Levels of sPLA2-IIA, eicosanoids prostaglandin (PG)E2, PGD synthase were quantified in the sera from patients confirmed to have bacterial sepsis (BS; N = 45), bacterial severe sepsis/septic shock (BSS/SS; N = 35) and healthy subjects (N = 45). Cyclooxygenase (COX)-1 and COX-2 activities were analyzed from cell lysate. Serum levels of sPLA2-IIA, PGE2, and PGDS increased significantly in patients with BS and BSS/SS compared to healthy subjects (p<0.05). COX-2 activity was significantly increased in patients with BS compared to healthy subjects (p<0.05), but not COX-1 activity. Binary logistic regression analysis showed that sPLA2-IIA and PGE2 were independent factors predicting BSS severity. In conclusion, high level of sPLA2-IIA is associated with eicosanoid metabolism in patients with BSS.

Should all children admitted with community acquired pneumonia have blood cultures taken?

Lai EM, Nathan AM, de Bruyne JA, Chan LL

Indian J Pediatr, 2015 May;82(5):439-44.
PMID: 25179241 DOI: 10.1007/s12098-014-1565-6

OBJECTIVE: To evaluate the yield of blood cultures and the impact of blood culture results on the adjustment of empiric antibiotic treatment in children hospitalised with community acquired pneumonia (CAP).
METHODS: This was a prospective study conducted at a tertiary hospital in Malaysia, from 1st August 2010 until 31st July 2011. Children aged between 1 mo and 12 y who were admitted for CAP and had blood cultures performed before starting intravenous antibiotics were recruited. Children with congenital pneumonia, immunodeficiency, chronic cardiac or respiratory disorders, nosocomial pneumonia or those on corticosteroids, were excluded. Decision for admission was made by the attending Accident and Emergency physician.
RESULTS: One hundred and seventy-one children were enrolled. The median age was 13 mo (range: 38 d-10 y 3 mo) and 59 % were males. Blood cultures were positive in 1.2 % (2/171) of patients while the contamination rate was 1.8 % (3/171). Doctors altered antibiotics based on blood culture results in only one patient.
CONCLUSIONS: Both the yield and the impact of blood culture results on the adjustment of empiric antibiotic treatment were very small. There was a high contamination rate. The recommended practice of performing blood cultures in all children admitted with CAP should be reviewed.
