Disseminated tuberculosis is a potentially fatal disease caused by the haematogenous spread of Mycobacterium tuberculosis. First-line anti-tuberculosis drugs in-clude isoniazid, rifampicin, pyrazinamide, and ethambutol. The first three drugs are known to cause hepatotoxicity.\u0000\u0000\u0000CASE PRESENTATION\u0000We have, herein, reported a case of Drug-induced Liver Injury (DILI) due to anti-tuberculosis therapy in a one-year-old male child with disseminated tuberculosis. He was started on a fixed-dose combination of Anti-tuberculosis Therapy (ATT; isoniazid 50 mg, rifampicin 75 mg, and pyrazinamide 150 mg) and pyridoxine 10 mg orally. Initially, liver pa-rameters were normal, but later on with the course of the treatment, there was a rapid rise in liver enzymes, suggesting liver injury.\u0000\u0000\u0000DISCUSSION\u0000The association between liver injury and anti-tuberculosis therapy has been con-firmed by applying various causality association scales. It is obvious that proper treatment of disseminated tuberculosis can avoid the development of drug-resistant strains that can be harm-ful, worsening the prognosis as there are fewer therapeutic alternatives available. At the same time, there is a need to monitor the patient with ATT-induced DILI.\u0000\u0000\u0000CONCLUSION\u0000The diagnosis of tuberculosis in children is difficult because of the mild, nonspe-cific clinical presentation, which usually reflects the implicated underlying organ. In addition to prompt diagnosis and treatment of disseminated TB, careful monitoring is equally important.","PeriodicalId":13678,"journal":{"name":"Infectious disorders drug targets","volume":" 25","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140683498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A conventional method of blood culture and Antimicrobial Susceptibility Testing (AST) takes around 48-72 hours. Empirical antibiotics need to be administered until the sensitivity report is made available. It has been estimated that 20-50% of the empirical antibiotics are inappropriate, resulting in prolonged hospital stays, adverse effects, and emergence of drug resistance. Additionally, this also puts an extra financial burden on both the patients and healthcare settings. Performing direct Antimicrobial Sensitivity Testing (dAST) is an important tool to reduce turn-around time (TAT) by at least 18-24 hours, thus reducing morbidity and mortality among critically ill patients.\u0000\u0000\u0000METHODS\u0000Direct AST (dAST) was performed from the positively flagged blood culture bottles received between December, 2021 to May, 2022 from Intensive Care Units (ICUs) on MuellerHinton Agar (MHA) using four drops of withdrawn blood. dAST was performed for six drugs: Ceftriaxone-30 µg (CTR), Piperacillin/Tazobactam-100/10 µg (PIT), Meropenem-10 µg (MRP), Ciprofloxacin-5 µg (CIP), Aztreonam-30 µg (AT), and Colistin (CL). The zone of inhibition was interpreted as per CLSI M100 ed32, 2022 guidelines. A parallel conventional method was also performed to examine for categorical agreement and disagreement. Identification was carried out using MALDI-TOF MS from the colonies that appeared on the dAST plate on the subsequent day.\u0000\u0000\u0000RESULTS\u0000A total of 162 positively flagged blood culture bottles were included in the study. The majority of the Gram-negative organisms were from Enterobacterales (n=109), followed by Acinetobacter spp. (n=28) and Pseudomonas aeruginosa (n=25). Out of the 972 isolate-antimicrobial combinations, overall Categorical Agreement (CA) was seen in 936 (96.3%), whereas disagreement was observed in 36 with minor error (mE) in 21 (2.2%), major error (ME) in 7 (0.7%), and very major error (VME) in 8 (0.8%) when compared to the routine method. Categorical agreement (CA) of > 99% was seen in ceftriaxone (CTR) and ciprofloxacin (CIP). In comparison, the lowest CA was observed with meropenem (MRP) at 92%. Colistin dAST was performed using the E-strip method, and the result obtained was highly convincing, with an overall disagreement of only 1.2%.\u0000\u0000\u0000CONCLUSION\u0000Rapid dAST from positively flagged blood culture bottles proved to significantly reduce the TAT from the time of sample collection to the first availability of antimicrobial susceptibility report with excellent categorical agreement of > 95% using the conventional disc diffusion method. Results obtained were within the acceptance criteria set by U. S. Food and Drug Administration (FDA) guidelines of > 90% categorical agreement for a new method. We were able to obtain excellent concordance for colistin using the E-strip method.
