Antibiotic Guidelines for Critically Ill Patients in Nigeria.

BACKGROUND: It is well documented that inappropriate use of antimicrobials is the major driver of antimicrobial resistance. To combat this, antibiotic stewardship has been demonstrated to reduce antibiotic usage, decrease the prevalence of resistance, lead to significant economic gains and better patients' outcomes. In Nigeria, antimicrobial guidelines for critically ill patients in intensive care units (ICUs), with infections are scarce. We set out to develop antimicrobial guidelines for this category of patients. METHODS: A committee of 12 experts, consisting of Clinical Microbiologists, Intensivists, Infectious Disease Physicians, Surgeons, and Anesthesiologists, collaborated to develop guidelines for managing infections in critically ill patients in Nigerian ICUs. The guidelines were based on evidence from published data and local prospective antibiograms from three ICUs in Lagos, Nigeria. The committee considered the availability of appropriate antimicrobial drugs in hospital formularies. Proposed recommendations were approved by consensus agreement among committee members. RESULTS: Candida albicans and Pseudomonas aeruginosa were the most common microorganisms isolated from the 3 ICUs, followed by Klebsiella pneumoniae, Acinetobacter baumannii, and Escherichia coli. Targeted therapy is recognized as the best approach in patient management. Based on various antibiograms and publications from different hospitals across the country, amikacin is recommended as the most effective empiric antibiotic against Enterobacterales and A. baumannii, while colistin and polymixin B showed high efficacy against all bacteria. Amoxicillin-clavulanate or ceftriaxone was recommended as the first-choice drug for community-acquired (CA) CA-pneumonia while piperacillin-tazobactam + amikacin was recommended as first choice for the treatment of healthcare-associated (HA) HA-pneumonia. For ventilatorassociated pneumonia (VAP), the consensus for the drug of first choice was agreed as meropenem. Amoxycillin-clavulanate +clindamycin was the consensus choice for CAskin and soft tissue infection (SSIS) and piperacillin-tazobactam + metronidazole ±vancomycin for HA-SSIS. Ceftriaxone-tazobactam or piperacillin-tazobactam + gentamicin was consensus for CA-blood stream infections (BSI) with first choice+regimen for HA-BSI being meropenem/piperacillin-tazobactam +amikacin +fluconazole. For community-acquired urinary tract infection (UTI), first choice antibiotic was ciprofloxacin or ceftriaxone with a catheter-associated UTI (CAUTI) regimen of first choice being meropenem + fluconazole. CONCLUSION: Data from a multicenter three ICU surveillance and antibiograms and publications from different hospitals in the country was used to produce this evidence-based Nigerian-specific antimicrobial treatment guidelines of critically ill patients in ICUs by a group of experts from different specialties in Nigeria. The implementation of this guideline will facilitate learning, continuous improvement of stewardship activities and provide a baseline for updating of guidelines to reflect evolving antibiotic needs.

CONTEXTE: Il est bien établi que l'utilisation inappropriée des antimicrobiens est le principal moteur de la résistance aux antimicrobiens. Pour lutter contre ce phénomène, il a été démontré que la bonne gestion des antibiotiques permettait de réduire l'utilisation des antibiotiques, de diminuer la prévalence de la résistance, de réaliser des gains économiques significatifs et d'améliorer les résultats pour les patients. Au Nigéria, les directives antimicrobiennes pour les patients gravement malades dans les unités de soins intensifs (USI), souffrant d'infections, sont rares. Nous avons entrepris d'élaborer des lignes directrices sur les antimicrobiens pour cette catégorie de patients. MÉTHODES UTILISÉES: Un comité de 12 experts, composé de microbiologistes cliniques, d'intensivistes, de médecins spécialistes des maladies infectieuses, de chirurgiens et d'anesthésistes, a collaboré à l'élaboration de lignes directrices pour la prise en charge des infections chez les patients gravement malades dans les unités de soins intensifs nigérianes. Les lignes directrices sont basées sur des données publiées et des antibiogrammes prospectifs locaux provenant de trois unités de soins intensifs de Lagos, au Nigeria. Le comité a pris en compte la disponibilité des médicaments antimicrobiens appropriés dans les formulaires des hôpitaux. Les recommandations proposées ont été approuvées par consensus entre les membres du comité. RÉSULTATS: Candida albicans et Pseudomonas aeruginosa étaient les microorganismes les plus fréquemment isolés dans les trois unités de soins intensifs, suivis par Klebsiella pneumoniae, Acinetobacter baumannii et Escherichia coli. La thérapie ciblée est reconnue comme la meilleure approche pour la prise en charge des patients. Sur la base de divers antibiogrammes et publications provenant de différents hôpitaux du pays, l'amikacine est recommandée comme l'antibiotique empirique le plus efficace contre les entérobactéries et A. baumannii, tandis que la colistine et la polymixine B se sont révélées très efficaces contre toutes les bactéries. L'amoxicilline-clavulanate ou la ceftriaxone ont été recommandées comme médicaments de premier choix pour les pneumonies communautaires, tandis que la pipéracilline-tazobactam + amikacine ont été recommandées comme médicaments de premier choix pour le traitement des pneumonies associées aux soins. Pour les pneumonies acquises sous ventilation mécanique (PAV), le consensus sur le médicament de premier choix est le méropénem. L'amoxycilline-clavulanate +clindamycine était le choix consensuel pour les infections de la peau et des tissus mous et la pipéracilline-tazobactam + métronidazole ±vancomycine pour les infections de la peau et des tissus mous. HA-SSIS. Ceftriaxone-tazobactam ou pipéracilline-tazobactam + gentamicine a fait l'objet d'un consensus pour les infections de la circulation sanguine de l'AC (BSI), le premier choix de régime pour les HA-BSI étant le méropénem/pipéracilline-tazobactam +amikacine +fluconazole. Pour les infections urinaires communautaires, l'antibiotique de premier choix était la ciprofloxacine ou la ceftriaxone, le régime de premier choix pour les infections urinaires associées à un cathéter étant le meropenem +fluconazole. CONCLUSION: Les données issues d'une surveillance multicentrique de trois unités de soins intensifs, d'antibiogrammes et de publications de différents hôpitaux du pays ont été utilisées par un groupe d'experts de différentes spécialités nigérianes pour élaborer ces lignes directrices sur le traitement antimicrobien des patients gravement malades dans les unités de soins intensifs, fondées sur des données probantes et spécifiques au Nigeria. La mise en œuvre de ces lignes directrices facilitera l'apprentissage, l'amélioration continue des activités de gestion et fournira une base de référence pour la mise à jour des lignes directrices afin de refléter l'évolution des besoins en antibiotiques.

Intussusception in pregnancy--a rarely considered diagnosis.

Intussusception in pregnancy is rare and making a preoperative diagnosis is extremely difficult. The objective of this paper is to report a case of intussusception in a pregnant woman and to review the literature on the subject with a view to highlighting the peculiarities of this condition. The case file of a 26 year old Gravida 3, Para(0+2) lady who had appendectomy 5 years earlier and now presented at 33 weeks of gestation with features of intestinal obstruction was evaluated. Ultrasound scan showed dilated bowel loops suggestive of intestinal obstruction. At operation, an ileo-ileal intussusception was found without a lead point. Histology of the resected bowel segment showed haemorrhagic infarction without evidence of malignancy. Even though bands and adhesions are the commonest causes of intestinal obstruction in a patient that has had a previous abdominal surgery, possibility of other aetiological factors should always be considered.

Gastric carcinoma--a big challenge in a poor economy.

BACKGROUND: Gastric carcinoma is usually characterized with significant morbidity and mortality mainly because of late presentation. Late presentation of gastric carcinoma is a prominent feature in developing and poor countries. AIM OF STUDY: The purpose of this study is to present our experience with the pattern and outcome of gastric tumors at the University of Benin Teaching Hospital, Benin City, Nigeria; with emphasis on late presentation of the patients. PATIENTS AND METHODS: The case files of the patients that were managed at the University of Benin Teaching Hospital for gastric tumors over a 5-year period (January 2004 to December 2006) were analyzed for biodata, symptoms and signs of disease, findings at operation, treatment offered, and outcome of treatment. RESULTS: The male/female ratio was 2.3:1, with the youngest patient being 38 years while the oldest patient was 76 years old. Upper abdominal pain and a palpable mass per abdomen were the commonest symptoms and signs, respectively. Alcohol ingestion was the commonest identifiable risk factor. Only 30.4% of the patients presented within a year of the onset of symptoms. The gastric antrum was affected in over 78% of the cases, and adenocarcinoma was found in about 90% of the patients. Partial gastrectomy with gastrojejunostomy was the commonest procedure carried out. The mortality rate was 39.1%, and of the patients that died, 66.7% occurred within a year from time of diagnosis. CONCLUSION: Most of the cases of gastric carcinoma presented in this study presented late with associated significant mortality. Health education is advised with a view to encouraging early presentation.

Indirect inguinal hernia in Nigerian older children and young adults: is herniorrhaphy necessary?

BACKGROUND: In many centers in sub-Saharan Africa, adults and children aged over 12 years with indirect inguinal hernias are treated with Bassini's herniorrhaphy with many avoidable complications. The objective of this study was to determine the applicability of herniotomy in patients aged between 12 and 45 years. METHODS: A prospective study was carried out on patients aged between 12 and 45 years with indirect inguinal hernias who were treated with herniotomy at the Leadeks Medical Center, Benin City, Nigeria, between January 2002 and December 2007. RESULTS: A total of 316 patients aged between 12 and 45 years (mean 25 +/- 5.3 years), comprising 305 males and 11 females with a male:female ratio of 27.7:1, had 326 herniotomies, which accounted for 27.5% of pediatric operations during the study period. Two hundred and eighty-three (86.8%) patients had elective while 43 (13.2%) had emergency surgery following features of obstruction and strangulation, with a mean duration of surgery of 30 min (range 20-40 min). All of the patients were operated on day case with a mean observation period of 8 +/- 3.5 h (range 2-24 h), and no significant immediate postoperative complication was recorded. Postoperative pain was extremely statistically significant in those cases that had strangulation before operation (P < 0.0001), but paracetamol was an adequate analgesia. The patients resumed normal duties between 5 and 14 days after repair and have been followed up for 1-5 years, with one (0.3%) patient, who was also being treated for chronic cough, who had recurrence 3 years after operation. CONCLUSION: Herniotomy was found to be safe, applicable, beneficial, and cost-effective in this age group, with many advantages over Bassini's herniorrhaphy.
