ABSTRACTBackground: Previous studies have described the use of cefazolin with probenecid to treat uncomplicated skin and soft-tissue infections. Some prescribers are extrapolating from this evidence to treat more invasive infections, which have a greater potential for poor outcomes, including treatment failure that could lead to increased morbidity and mortality. Information supporting cefazolin with probenecid as effective treatment in this context is needed.Objectives: To describe prescribing patterns and outcomes for patients who received cefazolin with probenecid for the treatment of bone and joint infections.Methods: This single-centre retrospective study involved adult outpatients for whom cefazolin and probenecid were prescribed for bone and joint infections between April 1, 2012, and March 31, 2017. Patient charts were reviewed, and data were collected for clinical and microbiological variables using a standardized data collection form.Results: In a total of 80 cases, the patient received cefazolin and probenecid for treatment of a bone or joint infection, of which 69 cases met the inclusion criteria. In most cases (n = 67), the patients were treated with cefazolin 2 g IV plus probenecid 1 g PO, both given twice daily. Completion of prescribed treatment occurred in 56 patient cases (81%), resolution of signs and symptoms in 53 (77%), readmission to hospital in 11 (16%), recurrence of infection in 6 (9%), and treatment failure requiring a change in therapy in 7 (10%).Conclusions: The effectiveness of cefazolin and probenecid for the treatment of bone and joint infections appears to be similar to that of standard treatment, as reported in the literature. Antibiotic effectiveness is difficult to determine conclusively in a retrospective analysis, so these results should be interpreted with caution, but they may stimulate further research.RÉSUMÉContexte : Des études précédentes ont décrit l’utilisation de la céfazoline et du probénécide pour traiter les infections cutanées et les infections de tissus mous. Quelques prescripteurs extrapolent ces éléments probants pour traiter des infections plus invasives, dont les résultats risquent d’être défavorables, comme un échec du traitement pouvant entraîner une morbidité et une mortalité accrues. De l’information supplémentaire étayant l’efficacité du traitement à l’aide de la céfazoline et du probénécide dans ce contexte est nécessaire.Objectifs : Décrire les modes de prescription et les résultats obtenus par des patients ayant reçu de la céfazoline et du probénécide pour traiter des infections osseuses et articulaires.Méthodes : Cette étude rétrospective unicentrique porte sur des patients ambulatoires adultes à qui on a prescrit de la céfazoline et du probénécide pour traiter des infections osseuses et articulaires entre le 1er avril 2012 et le 31 mars 2017. L’examen des dossiers médicaux des patients a permis la récolte de données sur les variables cliniques et microbiologiques à l’aide d’un formulaire de recueil de données standard.Résultats : Les patients, soit 80 cas en tout, ont reçu de la céfazoline et du probénécide pour traiter une infection osseuse ou articulaire et 69 de ces cas répondaient aux critères d’inclusion. Dans la plupart des cas (n = 67), les patients étaient traités avec de la céfazoline IV dosée à 2 g et du probénécide dosé à 1 g PO, les deux produits étant administrés deux fois par jour. Le traitement a été appliqué au complet dans 56 cas (81 %), la résolution des signes et des symptômes a eu lieu dans 53 cas (77 %), la réadmission à l’hôpital s’est produite dans 11 cas (16 %), les infections ont récidivé dans 6 cas (9 %) et le traitement s’est soldé par un échec et a nécessité un changement de thérapie dans 7 cas (10 %).Conclusions : L’efficacité de la céfazoline et du probénécide dans le traitement des infections osseuses et articulaires semble être similaire à celle des traitements standard, comme le rapporte la littérature scientifique. L’efficacité des antibiotiques est difficile à déterminer de façon concluante dans une analyse rétrospective, ces résultats doivent donc être interprétés avec prudence, mais ils pourraient stimuler des recherches supplémentaires.

: The prevalence of primary hypothyroidism is increasing in adults (PHTA), and the reduction in the threshold for treatment and also the requirement to increase drug usage are major problems in approaching this disorder. Persian Medicine (PM) looks from a different view on etiology of diseases. Therefore, we tried to present the etiologies of PHTA according to an important book of PM i.e. “Zakhire Kharazmshahi”. Method: At first, the common symptoms and signs of PHTA were identified by investigating the Medline, Scopus, and Cochrane databases and their Persian equivalents were extracted from PM sources. These synonyms were searched as keywords in the book and the primary causes that were mentioned in association with the signs and symptoms were extracted. Then, we explained the total etiologies that were discussed for the occurrence of the causes, with respect to the principles of health care in PM. Results: "Cold distemperament", an increase in "Phlegmatic Humor ", an increase in "Melancholic Humor" and "Emtela" (repletion) were recognized as four main causes of PHTA. According to the book, the most important etiologies of these conditions are insufficient exercise, overeating, food intake before total stomach emptying and excessive amounts of cold temperament substances (foods, herbs, seeds, spices, etc.) in daily diet. Conclusion: From the viewpoint of PM, lifestyle spatially eating habits and physical activity play important causative roles in occurring and prognosis of PHTA. Hence, it is recommended to assess these results by more observations and clinical studies.

The prevalence of enterococcal infection, especially E. faecium, is increasing, and the issue of the impact of vancomycin resistance on clinical outcomes is controversial. This study aimed to investigate the clinical outcomes of infection caused by E. faecium and determine the risk factors associated with mortality. This retrospective study was performed at the Phramongkutklao Hospital during the period from 2014 to 2018. One hundred and forty-five patients with E. faecium infections were enrolled. The 30-day and 90-day mortality rates of patients infected with vancomycin resistant (VR)-E. faecium vs. vancomycin susceptible (VS)-E. faecium were 57.7% vs. 38.7% and 69.2% vs. 47.1%, respectively. The median length of hospitalization was significantly longer in patients with VR-E. faecium infection. In logistic regression analysis, VR-E. faecium, Sequential Organ Failure Assessment (SOFA) scores, and bone and joint infections were significant risk factors associated with both 30-day and 90-day mortality. Moreover, Cox proportional hazards model showed that VR-E. faecium infection (HR 1.91; 95%CI 1.09–3.37), SOFA scores of 6–9 points (HR 2.69; 95%CI 1.15–6.29), SOFA scores ≥ 10 points (HR 3.71; 95%CI 1.70–8.13), and bone and joint infections (HR 0.08; 95%CI 0.01–0.62) were significant risk factors for mortality. In conclusion, the present study confirmed the impact of VR-E. faecium infection on mortality and hospitalization duration. Thus, the appropriate antibiotic regimen for VR-E. faecium infection, especially for severely ill patients, is an effective strategy for improving treatment outcomes.

Abstract. Background: Hematopoietic stem cell transplantation (HSCT) recipients are at increased risk for infection. This study describes bone and joint infections (BJI) among HSCT recipients.Methods: We reviewed 5861 patients who underwent HSCT at Mayo Clinic, Rochester, MN from January 1, 2005 through January 1, 2015 for study inclusion. BJI was defined as native septic arthritis, prosthetic joint infection, osteomyelitis, and orthopedic implant infection. All adults with BJI after HSCT were included in the analysis.Results: Of 5861 patients, 33 (0.6%) developed BJI. Native joint septic arthritis was the most common BJI occurring in 15/33 (45.4%) patients. Patients were predominantly male (24/33, 72.7%), with median age of 58 (range 20-72) years. BJI was diagnosed a median of 39 (range 1-114) months after allogeneic (14/33, 42.4%) or autologous (19/33, 57.6%) HSCT. Organisms were recovered via tissue (24/27, 88.9%), synovial fluid (13/17, 76.5%), and/or blood cultures (16/25, 64%). Most underwent surgical debridement (23/33, 69.7%). Patients were followed a median of 78.3 months (range 74-119). Therapy was unsuccessful in 4/33 (12.1%), with death related to the underlying BJI in two (50%). Failure occurred a median of 3.4 (0.1-48.5) months from diagnosis. At last follow up, 7/33 (21.2%) patients were alive. Median overall survival was 13 months (0.07-70.6).Conclusion: BJI among HSCT recipients is infrequent. The most common infection is native joint septic arthritis. Pathogens appear similar to patients without HSCT. Treatment involving surgical-medical modalities is successful, with most patients surviving >1 year after BJI.
