Antimicrobial susceptibility of Neisseria gonorrhoeae isolates and syndromic treatment of men with urethral discharge in Kingston, Jamaica, 2018-19.

OBJECTIVES: To quantitatively determine the antimicrobial susceptibility of clinical Neisseria gonorrhoeae isolates from men with urethral discharge in Jamaica and to describe the syndromic treatment therapies administered. METHODS: Urethral eSwabs (Copan) were collected from 175 men presenting with urethral discharge to the Comprehensive Health Centre STI Clinic, Kingston, Jamaica. Clinical information was collected and MICs of eight antimicrobials were determined for N. gonorrhoeae isolates (n = 96) using Etest and interpreted using CLSI criteria. RESULTS: The median age of the subjects was 28 years (range: 18-73 years) with a median of 2 sexual partners (range: 1-25) per male in the previous 3 months. All examined N. gonorrhoeae isolates were susceptible to ceftriaxone (96/96), azithromycin (91/91), cefixime (91/91) and spectinomycin (91/91). For ciprofloxacin and gentamicin, respectively, 98.9% (91/92) and 91.3% (84/92) of the isolates were susceptible and 1.1% (1/92) and 8.7% (8/92) showed intermediate susceptibility/resistance. For tetracycline and benzylpenicillin, respectively, 38.0% (35/92) and 22.0% (20/91) of the isolates were susceptible, 52.2% (48/92) and 74.7% (68/91) showed intermediate susceptibility/resistance and 9.8% (9/92) and 3.3% (3/91) were resistant. Syndromic treatment was administered as follows: 93.1% received 250 mg of ceftriaxone intramuscularly plus 100 mg of doxycycline orally q12h for 1-2 weeks and 6.9% received 500 mg of ciprofloxacin orally plus 100 mg of doxycycline orally q12h for 1 week. CONCLUSIONS: Ceftriaxone (250 mg) remains appropriate for gonorrhoea treatment in the examined population of men in Kingston, Jamaica. Surveillance of N. gonorrhoeae AMR should be expanded in Jamaica and other Caribbean countries to guide evidence-based treatment guidelines.

Public knowledge, attitude, and practice regarding antibiotics use in Punjab, Pakistan: a cross-sectional study.

OBJECTIVES: Public awareness about antibiotics use is critical in antimicrobial resistance. We evaluated knowledge, attitudes, and practices among the general population of Punjab, Pakistan in this cross-sectional study. METHODS: We used a 50-item questionnaire to collect information on participant demographics, knowledge, and attitudes about antibiotics use and to evaluate the practices of taking antibiotics without a doctor's prescription. RESULTS: Of the 2106 participants who completed surveys, 35.4% thought antibiotics could cure viral infections; 47.5% believed they are effective against cold and flu. Nearly 60% percent of respondents had self-medicated with antibiotics. Married people (adjusted odds ratio (AOR) = 1.285, 95% confidence interval (CI): 1.004-1.643 p = 0.046), higher antibiotics use knowledge (AOR = 0.818, 95% CI: 0.674-0.993 p = 0.042), ever purchased antibiotics without a physician's prescription (AOR = 2.024 95% CI: 1.674-2.457 p ≤ 0.001) and storing antibiotics at home (AOR = 0.801 95% CI: 0.652-0.985 p = 0.035) were significantly associated with self-medication practices. CONCLUSIONS: A high proportion of inappropriate antibiotics use exists among the general population of Punjab. Interventions are needed to improve health literacy and supervise antibiotics sales in retail pharmacies.

Prevalence, co-infection and antibiotic resistance of Escherichia Coli from blood and urine samples at a hospital in Jamaica.

INTRODUCTION: Escherichia coli (E. coli) is a very common uro-pathogen and pathogen of bloodstream infections (BSI) in Jamaica. The aim of this study was to examine this organism's prevalence, determine co-infection rates and assess antibiotic resistance patterns. METHODOLOGY: In the absence of automated systems, data on all E. coli isolates identified at the University Hospital of the West Indies in Kingston, Jamaica during the first six months of 2008 and 2012 was collected and sorted. Data were analyzed using IBM SPSS Statistics version 20 for Windows. RESULTS: A total of 1188 isolates (1072 from urine and 116 from blood) was analyzed. Patients with E. coli BSI were older than those with E. coli urinary tract infections (UTI) (55.3 years vs 42.4 years, p < 0.05) and both had a female predominance. Sensitivity profiles in 2012 for E. coli in blood and urine were highest for the carbapenems, Amikacin and Nitrofurantoin and lowest for the fluoroquinolones and Trimethoprim-sulfamethoxazole. Based on antimicrobial susceptibility patterns, Nitrofurantoin was identified as an appropriate choice for empiric therapy for UTI. Ten antibiotics were noted in this study to have developed statistically significant antibiotic resistance. Patients with E. coli BSI had a co-infection E. coli UTI rate of 39%. CONCLUSIONS: Resistance patterns change drastically in a few years making frequent antimicrobial susceptibility profiling necessary. Further studies would be beneficial in guiding management of these patients.

A national survey of the knowledge, attitudes and prescribing practices of doctors regarding antibiotic resistance in a Caribbean country.

Background: Antibiotic resistance (ABR) is a serious threat that requires coordinated global intervention to prevent its spread. There is limited data from the English-speaking Caribbean. Methods: As part of a national programme to address antibiotic resistance in Jamaica, a survey of the knowledge, attitudes and antibiotic prescribing practices of Jamaican physicians was conducted using a 32-item self-administered questionnaire. Results: Of the eight hundred physicians targeted, 87% responded. The majority thought the problem of resistance very important globally (82%), less nationally (73%) and even less (53%) in personal practices. Hospital physicians were more likely to consider antibiotic resistance important in their practice compared to those in outpatient practice or both (p < 0.001). Composite knowledge scores were generated and considered good if scored > 80%, average if 60-79% and poor if < 60%. Most had good knowledge of factors preventing resistance (83%) and resistance inducing potential of specific antibiotics (59%), but only average knowledge of factors contributing to resistance (57%). Knowledge of preventative factors was highest in females (p = 0.004), those with postgraduate training (p = 0.001) and those > four years post graduation (p = 0.03). Empiric therapy was often directed by international guidelines and cultures were not routinely done. Limited laboratory and human resources were identified as challenges. Conclusion: Physicians in this study were aware of the problem of ABR, but downplayed its significance nationally and personally. These results will guide a national antibiotic stewardship programme.

Genetic characteristics and molecular epidemiology of vancomycin-resistant Enterococci isolates from Caribbean countries.

Emergence of vancomycin-resistant Enterococci (VRE) that first appeared on the stage about three decades ago is now a major concern worldwide as it has globally reached every continent. Our aim was to simply undertake a multinational study to delineate the resistance and virulence genes of clinical isolates of VRE isolates from the Caribbean. We employed both conventional (standard microbiological methods including use of E-test strips, chromogenic agar) and molecular methods (polymerase chain reactions-PCR, pulsed-field gel electrophoresis-PFGE and multilocus sequence typing-MLST) to analyze and characterize 245 Enterococci species and 77 VRE isolates from twelve hospitals from eight countries in the Caribbean. The PCR confirmed and demonstrated the resistance and virulence genes (vanA and esp) among all confirmed VRE isolates. The PFGE delineated clonally related isolates from patients from the same country and other countries in the region. The main sequence types of the VRE isolates from the region included STs 412, 750, 203, 736 and 18, all from the common ancestor for clonal complex 17 (CC17). Despite this common ancestor and association of outbreaks of this lineage clones, there has been no reports of outbreaks of infection by VRE in several hospitals in the Caribbean.

Oral Bacterial Infections: Diagnosis and Management.

The human oral cavity contains more than 500 different bacterial species. These organisms belong to several phyla including Bacteroidetes, Firmicutes, Tenericutes, Actinobacteria, Proteobacteria, Euryarchaeota, Chlamydiae, and Spirochaetes. Many of these have the ability to colonize the gingival crevices and the outer surface of the tooth forming biofilms often leading to dental plaque formation. These bacteria produce acid that erode teeth causing cavities or infections. The diagnosis of these infections is often clinical and antibiotics are used empirically to treat some infections or as prophylaxis. The characterization, definitive diagnosis, and susceptibility testing of oral bacterial infections are valuable in guiding appropriate therapy and in prevention of disease.

Hand hygiene compliance by health care workers at a teaching hospital, Kingston, Jamaica.

INTRODUCTION: Consistent practice of hand hygiene (HH) has been shown to reduce the incidence and spread of hospital acquired infections. The objectives of this study were to determine the level of compliance and possible factors affecting compliance with HH practices among HCWs at a teaching hospital in Kingston, Jamaica. METHODOLOGY: A prospective observational study was undertaken at the University Hospital of the West Indies (UHWI) over a two weeks period. Trained, validated observers identified opportunities for hand hygiene as defined by the WHO "Five Hand Hygiene Moments" and recorded whether appropriate hand hygiene actions were taken or missed. Observations were covert to prevent the observer's presence influencing the behaviour of the healthcare workers (HCWs) and targeted areas included the intensive care units (ICUs), surgical wards and surgical outpatient departments. A ward infrastructure survey was also done. Data were entered and analysed using SPSS version 16 for Windows. Chi-square analysis using Pearson's formula was used to test associations between 'exposure' factors and the outcome 'compliance'. RESULTS: A total of 270 hand hygiene opportunities were observed and the overall compliance rate was 38.9%. No differences were observed between the various types of HCWs or seniority. HCWs were more likely to perform hand hygiene if the indication was 'after' rather than 'before' patient contact (p = 0.001). CONCLUSION: This study underscores the need for improvement in HH practices among HCWs in a teaching hospital. Health education with particular attention to the need for HH prior to physical contact with patients is indicated.

New Delhi metallo-ß-lactamase in Jamaica.

INTRODUCTION: The global dissemination of the New Delhi metallo-beta-lactamase (NDM) gene among certain strains of bacteria has serious implications since the infections caused by such organisms pose a therapeutic challenge. Although the NDM gene has been detected in various parts of the world, this is the first report of its detection in the English-speaking Caribbean. The NDM producing Klebsiella pneumoniae was isolated from an Indian patient who had recently relocated to Jamaica. METHODOLOGY: Identification and susceptibility testing of the K. pneumoniae isolate was performed using the Vitek 2 automated system) in keeping with Clinical and Laboratory Standards Institute (CLSI) standards. It was identified as a metallobetalactamase producer using the Rosco KPC+MBL kit. Genotypic screening for common betalactamase (including carbapenemase) genes, was carried out  using two multiplex PCRs: one for SHV-, TEM-, CTX-M-, OXA-1-, and CMY-2-types, and one for VIM-, KPC-, IMP-, OXA-48, GES-, and NDM-types. Strain typing was conducted by pulsed-field gel electrophoresis (PFGE) using XbaI and multi-locus sequencing (MLS). Plasmid isolation and analysis was also performed. RESULTS: K. pneumoniae (N11-02395), not previously associated with the dissemination of the NDM in India, Sweden or the UK, was found to harbor the NDM-1 gene on plasmid pNDM112395. CONCLUSION: The identification of the NDM-1 gene underscores the need for effective surveillance and infection control measures to identify and prevent spread of multidrug resistant Gram negative bacilli. Strict infection control measures implemented for this patient helped to prevent the spread of this organism to other patients.

A case of Candida orthopsilosis associated septic arthritis in a patient with Systemic Lupus Erythematosus (SLE).

We report a case of persistent Candida orthopsilosis associated septic arthritis. Repeated isolation of C. orthopsilosis from tissue and joint fluid was confirmed by identification of the ITS region of the rRNA gene using a Candida-Specific Luminex based assay and gene sequencing of the D1/D2 regions. This was the first case of C. orthopsilosis associated septic arthritis reported in Jamaica and in the literature.

Major West Indies MRSA clones in human beings: do they travel with their hosts?

BACKGROUND: Descriptions of the epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) have seldom been produced in the Caribbean, which is a major tourism destination. MATERIALS AND METHODS: Using DNA microarrays and spa typing, we characterized 85 MRSA isolates from human skin and soft-tissue infections from five different islands. RESULTS: In the French West Indies (n = 72), the most frequently isolated clones were the same clones that are specifically isolated from mainland France [Lyon (n = 35) and Geraldine (n = 11) clones], whereas the clones that were most frequently isolated from the other islands (n = 13) corresponded with clones that have a worldwide endemic spread [Vienna/Hungarian/Brazilian (n = 5), Panton Valentine leukocidin-positive USA300 (n = 4), New York/Japan (n = 2), and pediatric (n = 1) clones]. CONCLUSION: The distribution of the major MRSA clones in the French (Guadeloupe and Martinique) and non-French West Indies (Jamaica, Trinidad, and Tobago) is different, and the clones most closely resemble those found in the home countries of the travelers who visit the islands most frequently. The distribution might be affected by tourist migration, which is specific to each island.

Diphtheroids as a cause of endocarditis in a haemodialysis patient.

The authors report a fatal case of Corynebacterium sp. endocarditis. Corynebacterium spp. are non-sporulating, pleomorphic Gram-positive bacilli. In particular the authors have identified a species of Corynebacterium very closely related to C striatum. This is C simulans. The authors were able to identify the genus and species using various phenotypic tests. Highlighted here is the importance of identifying diphtheroids as a significant pathogen in the appropriate setting and the need to start antibiotic therapy if this is suspected.

Implementing end of life care for patients with renal failure.

Traditional palliative care services have focused on individuals with cancer. The NHS National End of Life Care Programme, launched in December 2003, has been working to address this anomaly and to try to enhance end of life care provision for other patient groups. This article reports on work in the area of renal failure at Westmorland General Hospital, Cumbria, where the Preferred Priorities for Care tool has been introduced to support patients nearing the end of life.

Photobacterium damsela bacteremia in a child with sickle-cell disease.

Photobacterium damsela was identified in a blood culture taken from a child with sickle-cell disease. This is the first report of this organism in humans in the Caribbean. The microbiology of this organism and its identification are discussed. The clinical presentation in humans and the role of the immune status of the patient are reviewed.

The effectiveness of the Gram stain of high vaginal swabs in the diagnosis of bacterial vaginosis at the University Hospital of the West Indies [abstract]

OBJECTIVE: To correlate the gram-stain of high vaginal swabs (HVS) with the diagnosis of bacterial vaginosis (BV) and to compare this with bacterial culture reports to determine whether any useful additional information is gained by culture. METHODS: HVS submitted to the microbiology laboratory (UWI) from patients diagnosed clinically with vaginal infection were used in this study. Specimens were submitted from the Family Planning, Gynaecology and Antenatal clinics at the University Hospital of the West Indies. Swabs were placed in Stuart's Transport Medium and taken to the microbiology laboratory within 24 hours. The specimens were subjected to standard bacteriological procedures of culture on blood and MacConkey agar and microscopic procedures of wet prepartion and gram stain. The gramstain was recorded on a specially designed data sheet for each patient with a standardized scoring method for the evaluation of gram-stained smears based on the recognition of both presence and amount of significant morphotypes. This result was then compared with the bacterial culture, available a few days later, to see the degree of correlation and to determine whether any relevant additional information was gained. Almost 60 percent of the specimens collected yielded no pathogens on culture. However, one-third of this 60 percent was diagnosed as BV by standardized scoring method. One-third of all specimens submitted yielded yeast (Candida albicans and yeast not-Candida albicans) on culture and by gram stain. Streptococcus group B was isolated in < 4 percent of all specimens and a miscellaneous group of organisms including Klebsiella sp, Pseudomonas sp and anaerobic Streptoccus made up the rest of bacterial isolates. CONCLUSIONS: The standardized scoring method of evaluating the HVS gram stains yielded a more accurate and rapid diagnosis of BV than the traditional culture method. This is worthy of further study, as implementation of this method would result in considerable cost and time saving. (AU)

Systemic phaeohyphomycosis in pregnancy and the puerperium

Systemic fungal infections are rare. In pregnancy, treatment is problematic because of the risk of possible teratogenic effects of the antifungal drugs. We present the case of a 32 year-old woman who presented during pregnancy with a two-month history of painless subcutaneous nodules. Excision biopsy of one lesion showed dematiaceous fungal elements. Anti-fungal treatment was deferred and the pregnancy proceeded uneventfully. The remaining nodules were excised at the time of caesarean section delivery. Three weeks into the puerperium, she developed generalised seizures and investigations indicated systemic fungal infection with positive cultures for Aureobasidium spp which responded to appropriate antifungal therapy of flucytosine and itraconazole.(Au)

Cancrum oris (noma) in a patient with acute lymphoblastic leukaemia. A complication of chemotherapy induced neutropenia

Cancrum oris (noma) has been most commonly described in malnourished debilitated children with poor oral hygiene following systemic childhood infections such as measles, pertussis or scarlet fever. We describe a patient who developed this condition during a period of profound neutropenia following cytotoxic chemotherapy for acute lymphoblastic leukaemia(AU)

The incidence and management of life-threatening arrhythmias occurring during the course of acute myocardial infarction - abstract

During the last decade the early detection and successful treatment of life-treatening arrhythmias have resulted in a significant reduction in the mortality rate of patients with myocardial infarction. The purpose of this study was to determine the incidence of these dangerous arrhythmias and to explore the possibility of producing a similar reduction in mortality rate with our limited resources. Since the 1st July, 1971, all patients with clinical diagnosis of acute myocardial infarction have been admitted to a coronary bed in either the intensive care unit or one of our general medical wards. Each be is fully equipped with a cardioscope for the continual monitoring of the patient's electrocardiogram, a defibrillator/cardioverter and the necessary anti-arrhythmic drugs and resuscitative equipment. During the first 7 months of this project a total of 24 patients with unequivocal evidence of myocardial infarction were admitted to the study and their rhythm was continually monitored for period varying from at least 48 hours up to 21 days. Four patients died from cardiogenic shock and in addition 2 of these patients had bronchopneumonia. Nine of the 24 patients showed a significant rhythm change (40 percent) and of these, 5 patients (20 percent) had a life-threatening arrhythmia. These included (a) fast atrial fibrillation, (b) sinus bradycardia with Stokes-Adams attacks, (c) complete heart block with Strokes-Adams attack, (d) ventricular tachycardia and (e) ventricular fibrillation were treated with a combination of practolol and digoxin with cardioversion being reserved for resistant cases. Sinus bradycardia was treated with frequent doses of atropine (0.6 mgm. I.M. 2 to 6 hourly) and complete heart block was controlled by transvenous endocardial pacing. Lignocaine was used as the drug of choice for ventricular tachycardia and so far there have been no cases of ventricular tachycardia which have been resistant to this drug. Ventricular fibrillation was treated with immediate defibrillation starting at an energy level of 300 Watts Seconds. It is concluded that serious arrhythmias do occur in at least 20 percent of our patients with acute myocardial infarction and we have demonstrated that these can be successfully treated here (AU)
