Typhoidal Salmonella strains in Pakistan: an impending threat of extensively drug-resistant Salmonella Typhi.
The aim of this study is to see the frequency, clinical presentation, and therapeutic response of extensively drug-resistant Salmonella enterica serovar Typhi and current susceptibility pattern of typhoidal Salmonella strains in our setup. This study was carried out at the Department of Medical Microbiology and Immunology and Department of Medicine, Pakistan Navy Ship (PNS) Shifa Hospital, Karachi, from January 1 to December 31, 2018. All the blood culture samples of patients (indoor and outdoor) with suspicion of enteric fever were processed. ⋯ Only 10 cases were given azithromycin who responded to treatment in mean 4.3 days. Out of 115 cases of XDR Salmonella Typhi, 103 patients were given parenteral meropenem and clinical response was seen in mean 5 days. The emergence and rapid spread of extensively drug-resistant Salmonella Typhi is alarming and highlights the significance of strict antimicrobial susceptibility surveillance programs with antimicrobial stewardship.

Evaluating the optimal dose of teicoplanin with therapeutic drug monitoring: not too high for adverse event, not too low for treatment efficacy.
Therapeutic drug monitoring (TDM) of teicoplanin is aimed at minimizing the clinical impact of pharmacokinetic variability; however, its benefits are still being defined. We performed a retrospective study of teicoplanin TDM focusing on the dose-serum concentration relationship and clinical outcomes in a clinical setting. From January 2017 to December 2018, patients receiving teicoplanin ≥ 72 h with TDM were enrolled. ⋯ In the subgroup analysis, HD regimen (P = 0.050) and high mean Cmin over 10 days (P = 0.025) were significantly associated with treatment success. Although HL regimen could achieve Cmin targets and improve clinical outcome during teicoplanin treatment, high Cmin was associated with AEs during treatment. Routine TDM can be helpful to optimize teicoplanin administration.
