Clinical spectrum and outcomes of patients with different resistance patterns of .

BACKGROUND AND OBJECTIVE

Unceasing rise in cases of enteric fever, in particular extensively drug resistant (XDR) strain of Salmonella enterica, has led to a growing threat, leaving only carbapenems and azithromycin as the precious option. In this regard, we determined the burden and clinical course of XDR salmonella in comparison to multidrug-resistant (MDR) and drug sensitive (DS) strains.

METHODS

A retrospective chart review of 1515 Salmonella Typhi (S.typhi) culture positive patients was conducted at Indus Hospital and Health Network, Karachi from July 2017 to December 2018.

RESULTS

During our study, we observed children at the age of 5-6 years and adults at the age of 20-22 years were the chief targets of S.typhi. Further, we witnessed a rapid shift of drug resistance from MDR to XDR over the one year of study. Almost all patients presented with fever. However other signs and symptoms like malaise, body aches, anorexia, diarrhea, vomiting and abdominal pain were more common in XDR Typhoid patients. Further, the need of hospitalization, total hospital stay and mortality was also greater for XDR typhoid patients.

CONCLUSION

There is a crucial requirement for consolidated steps to curtail the spread of XDR Salmonella tyhi disease as its management is challenging, and it is associated with increased morbidity and mortality.
