CASE PRESENTATION: Melioidosis is uncommon in pregnancy but both spontaneous abortion and neonatal melioidosis have been reported. We report a case of bacteraemic melioidosis in a young woman with a subsequent spontaneous abortion, with B. pseudomallei cultured from a high vaginal swab as well as blood.
CONCLUSION: It remains unclear in this and previously reported cases as to whether the maternal melioidosis was sexually transmitted.
METHODS: We reviewed 39 cases of splenic abscesses in a district hospital in Kapit, Sarawak, from January 2017 to December 2018. The demographics, clinical characteristics, underlying diseases, causative organisms, therapeutic methods, and mortality rates were investigated.
RESULTS: There were 21 males and 18 females (mean age, 33.7±2.7 years). Almost all patients (97.4%) had a history of pyrexia. Diabetes mellitus was present in 8 patients (20.5%). Splenic abscesses were diagnosed using ultrasonography and were multiple in all 39 cases. Positive blood cultures were obtained in 20 patients (51.3%), and all yielded B. pseudomallei. Melioidosis serology was positive in 9 of 19 patients (47.4%) with negative blood cultures. All patients were treated for melioidosis with antibiotics without the need for surgical intervention. All splenic abscesses resolved after anti-melioidosis treatment was completed. One patient died (2.6%) as a result of B. pseudomallei septicaemia with multiorgan failure.
CONCLUSIONS: Ultrasonography is a valuable tool for diagnosing splenic abscesses in resource-limited settings. B. pseudomallei was the most common etiological agent of splenic abscesses in our study.
METHODS: This was an observational study conducted among sepsis patients presented to ED of a tertiary university hospital from 18th January 2021 until 28th February 2021. ED overcrowding status was determined using the National Emergency Department Overcrowding Score (NEDOCS) scoring system. Sepsis patients were identified using Sequential Organ Failure Assessment (SOFA) scores and their door-to-antibiotic time (DTA) were recorded. Patient outcomes were hospital length of stay (LOS) and in-hospital mortality. Statistical analysis was done using Statistical Package for Social Sciences (SPSS) version 26. P-value of less than 0.05 for a two-sided test was considered statistically significant.
RESULTS: Total of 170 patients were recruited. Among them, 33 patients presented with septic shock and only 15% (n = 5) received antibiotics within one hour. Of 137 sepsis patients without shock, 58.4% (n = 80) received antibiotics within three hours. We found no significant association between ED overcrowding with DTA time (p = 0.989) and LOS (p = 0.403). However, in-hospital mortality increased two times during overcrowded ED (95% CI 1-4; p = 0.041).
CONCLUSION: ED overcrowding has no significant impact on DTA and LOS which are crucial indicators of sepsis care quality but it increases overall mortality outcome. Further research is needed to explore other factors such as lack of resources, delay in initiating fluid resuscitation or vasopressor so as to improve sepsis patient care during ED overcrowding.
MATERIALS AND METHODS: A total of 7204 clinical specimens from HIV patients from 2012 to 2017 were processed for the isolation of S. aureus strains using conventional culture techniques and cultures were identified using standard biochemical test. Antibiotic susceptibility of S. aureus strains was tested by Kirby-Bauer disk diffusion method.
RESULTS: A total of 380 (5.3%) S. aureus strains were isolated from HIV patients in the study period. High percentage of S. aureus strains were isolates from urine (69.5%) specimen and 58.4% of S. aureus infections were noted among hospitalized patients. Antibiotic susceptibility profile reveals S. aureus was highly resistant to penicillin (95.2%) followed by cephalexin (84.6%). Methicillin resistance was highly observed in the year 2017 (86%) and the rate of MRSA steadily increasing from 51.8% in 2012 to 86% in 2017. Significant increase of S. aureus infections (35%; p<0.001) and MRSA (76%; p=0.0007) were observed in the year 2016.
CONCLUSIONS: This study reports the increasing trends of S. aureus infections and MRSA among HIV patients from Southern India. Multidrug-resistance profile of S. aureus could complicate the selection of proper antibiotic regimens and time cure of HIV patients.
METHODS: This is a retrospective cohort single-centre study from 1 November 2006 to 29 May 2019, in all adult patients admitted with first episode of PAB. Data collected included demographics, clinical management and outcomes for PAB and whether IDC occurred. In addition, 29 Pseudomonas aeruginosa (PA) stored isolates were available for Illumina whole genome sequencing to investigate if pathogen factors contributed to the mortality.
RESULTS: A total of 128 cases of PAB were identified, 71% received IDC. Patients who received IDC were less likely to receive inappropriate duration of antibiotic therapy (4.4%; vs 67.6%; p
Methods: We searched 4 electronic databases (Medline, the Cochrane Central Register of Controlled Trials, Embase, CINAHL) and internet sources for randomized controlled trials, ongoing clinical trials, and unpublished studies up to August 2016. Studies that assessed CVCs with antimicrobial impregnation with nonimpregnated catheters or catheters with another impregnation were included. Primary outcomes were clinically diagnosed sepsis, catheter-related bloodstream infection (CRBSI), and all-cause mortality. We performed a network meta-analysis to estimate risk ratio (RR) with 95% confidence interval (CI).
Results: Sixty studies with 17255 catheters were included. The effects of 14 impregnations were investigated. Both CRBSI and catheter colonization were the most commonly evaluated outcomes. Silver-impregnated CVCs significantly reduced clinically diagnosed sepsis compared with silver-impregnated cuffs (RR, 0.54 [95% CI, .29-.99]). When compared to no impregnation, significant CRBSI reduction was associated with minocycline-rifampicin (RR, 0.29 [95% CI, .16-.52]) and silver (RR, 0.57 [95% CI, .38-.86]) impregnations. No impregnations significantly reduced all-cause mortality. For catheter colonization, significant decreases were shown by miconazole-rifampicin (RR, 0.14 [95% CI, .05-.36]), 5-fluorouracil (RR, 0.34 [95% CI, .14-.82]), and chlorhexidine-silver sulfadiazine (RR, 0.60 [95% CI, .50-.72]) impregnations compared with no impregnation. None of the studies evaluated antibiotic/antiseptic resistance as the outcome.
Conclusions: Current evidence suggests that the minocycline-rifampicin-impregnated CVC appears to be the most effective in preventing CRBSI. However, its overall benefits in reducing clinical sepsis and mortality remain uncertain. Surveillance for antibiotic resistance attributed to the routine use of antimicrobial-impregnated CVCs should be emphasized in future trials.
METHODOLOGY: Cross-sectional study was conducted at 13 hospitals and 44 primary health clinics in Perak from May to July 2017. Adults above 18 years, literate, and had experience in antibiotics consumption were selected through sequential sampling method. Data was collected using a self-administered questionnaire which included the three study domains i.e. belief, knowledge and practice. The questionnaire was pilot on 30 subjects.
RESULTS: Out of 2850 distributed questionnaires, 2773 returned and 2632 were included for analysis. Mean age of the respondents was 39.7 ± 14.5 years old. Most respondents were female (58.6%), Malay (74.7%) and underwent upper secondary school (45.6%). Mean score were generated for each domain with belief: 5.87 ± 3.00 (total score: 12), knowledge: 15.82 ± 3.85 (total score: 24), practice: 6.91 ± 2.07 (total score: 12). In the belief domain, 63.2% of respondents believed that antibiotics would help them to recover faster. In the knowledge domain, 52.7% of respondents inappropriately thought that antibiotics could work on viral infections. In the practice domain, 70% of respondents expected doctors to prescribe antibiotics if suffered from symptoms.
CONCLUSION: Majority of the respondents expect doctors to prescribe antibiotics for their illness, and most believes that antibiotics can speed up recovery of illness. Lack of awareness on antibiotic resistance was found to be a significant factor associated with inappropriate antibiotic use.
