Prevalence and antibiotic susceptibility pattern of esbl producing klebsiellae isolated from clinical specimens in a nigerian tertiary hospital

Background: Infection by Extended Spectrum Beta Lactamases (ESBLs) producing bacteria is a threat to man as a consequence of treatment challenges. This study evaluated the prevalence and antimicrobial susceptibility pattern of ESBL producing Klebsiellae (EPK) in clinical specimens at the University of Ilorin Teaching hospital, Ilorin (UITH), Nigeria. Methods: ESBL production was assayed using Double Discs Synergy Test (DDST). Antimicrobial susceptibility was performed by Modified Kirby-Baeur method with the organism tested against ceftazidime (30µg), cefotaxime (30µg), amoxicillin clavulinic acid (20/10µg), cefepime (30µg), ciprofloxacin (5µg), gentamicin (10µg), trimethoprim-sulphamethoxazole (23.75/1.25µg), imipenem (10µg) and doripenem (10µg) (Oxoid, UK). Results: Fifty (26.7%) of the 187 Klebsiellae studied were EPK comprising of 37(26.8%) Klebsiella pneumoniae and 13(26.5%) Klebsiella oxytoca. EPK were mostly from wound specimens (24.0%) although Klebsiellae were mostly occurring in sputum (26.2%). The EPK were resistant to ceftazidime (100%), cefotaxime (94.0%), trimethoprim-sulphamethoxazole (92.0%), gentamicin (70.0%) and ciprofloxacin (70.0%) but 100% susceptible to both doripenem and imipenem. Conclusion: The prevalence of EPK in this study is high and they are multi-drug resistant. Carbapenems are the best antibiotic treatment option for infections arising from these organisms although a coordinated rational usage is desired along with functional antibiotic prescription policy to avoid treatment failures. Continuous surveillance for ESBL producing Klebsiellae and resistance monitoring are necessary routine to strengthen infection control policies

Presentation and Outcome of Microbial Keratitis in Ilorin, Nigeria.

Aim: To determine the presentation and outcome of microbial keratitis among patients at University of Ilorin Teaching Hospital (UITH) in Ilorin, Nigeria. Methods: A 12-month, prospective, hospital-based longitudinal study was conducted by examining all patients with clinical features of infective keratitis, who met the inclusion criteria. A posttreatment evaluation was done at 6 weeks in all cases, during which visual acuity and any complications were re-assessed. The outcome measures included interval between onset and presentation, extent of corneal involvement and final visual acuity. The data was analysed with the SPSS version 20.0 software. Results: Fifty-five eyes of 54 patients were studied. There were 32 males (59.3%) and 22 females (40.7%). The mean age was 36.9 years (± 12.1). The predisposing factors were trauma in 30 (55.6%) cases, self-medication with topical steroids in 12 (22.2%) and the use of traditional eye medication in 12 (22.2%). All of the participants presented with pain, tearing, photophobia and reduction in vision. The right eye was involved in 37 patients (67.2%). The presenting visual acuity in the affected eyes was 6/60 or less in 31 (56.4%), 6/60–6/24 in 18 (32.7%) and 6/6–6/18 in 6 eyes (10.9%). At 6-week follow-up, 5 eyes (9.1%) had <6/60 visual acuity, 40 (72.7%) had 6/60– 6/24 and 10 (18.2%) had 6/6–6/18.The risk factors for poor outcome were a centrally located lesion (p=0.018), an area of corneal involvement greater than 4mm (p=0.007) and a lesion affecting the deeper layers of the cornea (p=0.002). Conclusion: Microbial keratitis is a significant cause of ocular morbidity, and public eye-health education is highly desirable as a preventive measure.

Prevalence of Extended Spectrum beta-Lactamase-Producing Klebsiella Species at the University of Ilorin Teaching Hospital

Background: Persistent blind antibiotic treatment of patients; in resource poor nations like Nigeria; makes the prevalence of antibiotic resistance to increase sporadically. Extended spectrum beta-lactamase (ESBL) production is one of the ways by which bacteria become resistant to antibiotics. For this reason; isolation; identification; sensitivity and screening for possible resistance genes is very important before prescription; if the affected patients must receive qualitative care particularly when their condition is chronic. Materials and Methods: Four hundred suspected isolates of Klebsiella belonging to various species obtained from routine specimens such as swabs; urine; blood; and sputum from May to October 2009 were studied. The identity of all isolates obtained was biochemically analyzed. The isolates were subjected to antibiotic susceptibility testing using modified Kirby-Bauer method and ESBL production was phenotypically determined using double disc synergy test for laboratory detection and reporting of bacteria by CLSI method. Results: Ninety-eight (24.5%) isolates expressed ESBL. Majority of the ESBL producing isolates were from swab specimens 59 (14.75%) followed by blood culture 16 (4.0%); urine 13 (3.25%); and sputum 10 (2.5%). Sensitivity patterns of ESBL producing Klebsiella spp. revealed that all ware resistant to augmentin (AUG); ceftazidime (CAZ); cefotaxime (CTX); cefuroxime (CRO); cefpodoxime (CPD); and none resistant to imipenem (IMP).Conclusion: ESBL producing Klebsiella spp.; were present in University of Ilorin Teaching Hospital. They are resistant to augmentin (AUG); CAZ; CTX; and CPD. Presence of ESBL in any Klebsiella spp. has made cephalosporins which are first line antibiotics usually given non-effective; thereby reducing the treatment options. We; therefore; suggest screening and confirmation for ESBL; in other to prevent treatment failure

Epidemiology, etiology, and treatment of chronic leg ulcer: experience with sixty patients

Background: Chronic leg ulcer (CLU) is reported to have an impact on virtually all aspects of life. Treatment is expensive and has large economic burden on many countries' health services. This presentation is to determine the impact; etiology; and presentation of CLU as well as the procedures for processing in a Nigeria tertiary care facility. Methods: All patients with CLU seen that were prospectively managed in our hospital between 2004 and 2006 have been included in the study. The data were analyzed by SPSS version 11.0 of software. Results: Sixty consecutive patients seen over a period of 3 years (2004-2006) were prospectively studied. There were two peak period of age presentation 30-39 and 50-69 years. The male female ratio was 1:1. Most of the patients (93.3) had unilateral ulcers and it was as common on the right as on the left. Fifty percent of patients had medical disorders. The commonest cause of CLU was poorly managed traumatic wound. Conclusion: Most patients benefited from debridement with or without split thickness skin graft or flap

Mortality pattern within twenty-four hours of emergency paediatric admission in a resource-poor nation health facility

BACKGROUND: Mortality among emergency paediatric admissions within the first 24 hours is high in resource- poor nations. Measures to reduce the childhood mortality rate can only be effectively planned and implemented when the causes and magnitude of this problem are well defined. OBJECTIVE: To determine the mortality pattern among emergency paediatric admissions within the first 24 hours in a health facility in Nigeria. METHODS: The clinical state and progress of post-neonatal patients who presented alive and were admitted into the emergency paediatric room of the University of Ilorin Teaching Hospital; Ilorin; Nigeria were monitored over a period of six months. The monitoring included records of diagnosis and outcome of management. RESULTS: A total of 606 children were admitted during the period of study out of which 51(8.4) died. Twenty-nine (57) of the deaths occurred within the first 24 hours of admission comprising 15 (51.7) males and 14 (48.3) females giving M:F ratio of about of 1:1. Majority of the deaths were among patients who reported late to the hospital. Loss of consciousness was a strong risk factor for mortality within 24 hours of admission. The highest mortality within the first 24 hours of admission was recorded among patients with malaria (89.0) followed by protein energy malnutrition. CONCLUSION: Majority of deaths among emergency paediatric admission occur within the first 24 hours of admission and are associated with clinical conditions such as malaria and protein-energy malnutrition for which sustained intervention strategies must be developed

Bacteriological Pattern of Wound Swab Isolates in Patients with Chronic Leg Ulcer

Purpose: To determine the pattern of bacterial pathogens and their antibiotic sensitivity profile in patients with infected chronic leg ulceration. Methods: Sixty swab specimens obtained from chronic leg ulcer (CLU) patients were cultured aerobically and the antibiotic sensitivity pattern of the recovered organisms determined by the modified Kirby -Bauer disc-diffusion method. Results: 47 (78.3) of the ulcers were infected out of which 39 (83.0) were culture positive. Most of the culture positive ulcers were on the distal third of the leg. The isolated bacteria from the wounds were Pseudomonas aeruginosa (33); Staphylococcus aureus (24); Proteus spp (15); Klebsiella spp (13); Citrobacter spp (13) and Escherichia coli (2). None of the patient without clinical evidence of wound infection had bacterial positive wound swab culture. All isolates were sensitive to third generation cephalosporin and floroquinolones but majority were resistant to ampicillin. Conclusion: Pseudomonas aeruginosa; Staphyloco-ccus aureus. Proteus spp; Klebsiella spp; Citrobacter spp and Escherichia coli sensitive to third generation cephalosporin and floroquinolones have been recovered from 78of patients with chronic leg ulcers in a tertiary health facility in Nigeria
