Background Drug-induced liver injury (DILI) represents an increasing morbidity in the general population, but more so in the elderly cohort of patients. Despite this, the concept of its prevention through prospective analysis has largely remained unexamined. We evaluated the utility of recently validated adverse drug reactions (ADR) avoidability tool in a cohort of elderly patients with DILI. Methods We examined 38 DILI-drug pairs from n=38 patients in a prospective cohort of patients presenting with adverse drug reactions to a Weill Cornell-affiliated tertiary hospital between February 2019 and January 2020. DILI outcomes were adjudicated by the updated Roussel Uclaf Causality Assessment Method (RUCAM). Two clinical pharmacologists and two general physicians utilized the Liverpool adverse drug reactions avoidability tool (LAAT) and the modified Hallas tools to rate the preventability of DILI-drug pairs. Inter-rater, exact agreement proportions, as well as intraclass correlation coefficients were generated and expressed as ordinal outcomes. Results The cases examined for the determination of DILI avoidability had probability likelihood of “probable” or “highly probable” by the updated RUCAM scale. Examination of the 38 DILI-drug pairs (n= 38 patients) resulted in a total of 152 ordinal outcome decisions. We found about 32.3% (50/152) and 34.2% (52/152) of DILI-drug pairs were rated as “avoidable” (“probable” or “definite”) by the LAAT and the modified Hallas tools respectively. The overall median Krippendorf’s kappa with the LAAT was 0.61 (SE 0.12, CI 0.36, 0.85) and for modified Hallas tool was 0.53 (SE 0.18; CI 0.16, 0.89). The inter-rater correlation coefficient (ICC) for the LAAT and modified Hallas were 0.50 [0.32, 0.65] and 0.63 [0.48, 0.76] respectively. Exact pairwise agreement was present in 30/38 (IQR 29.5, 34.5), and 28/38 (IQR 27.5-35.5) of DILI-ADR pairs using the LAAT and modified Hallas tools respectively. Conclusion We found a significant proportion of drug-induced liver injury adjudicated by the updated RUCAM scale in elderly hospitalized cohort of patients were avoidable with significant implication for therapeutic commissioning as well as cost effectiveness interventions in this cohort of patients.
Klebsiella pneumoniae (K. pneumoniae) is a Gram-negative bacteria that can infect most of the body's organs, from the lungs to the central nervous system. It is notorious for causing pneumonia in alcoholic, diabetic, and hospitalized patients. It is now emerging as a cause of abscesses involving multiple organs. Invasive K. pneumoniae is most commonly observed in the Asian population but has been reported in other geographical areas as well. We present a case of invasive K. pneumoniae. The patient was initially admitted with diabetic ketoacidosis (DKA); further investigations showed multiple abscesses involving the liver, lungs, brain, and muscles. K. pneumoniae was identified in blood and liver abscess cultures. The patient was managed for DKA as per protocol, and was administered broad-spectrum antibiotics with percutaneous drainage of liver abscess for invasive K. pneumoniae syndrome. In this paper, we highlight the invasive nature of K. pneumoniae, which may aid clinicians in diagnosing and managing similar cases, thereby preventing the associated high morbidity and mortality.
Pulmonary tuberculosis is a common endemic disease in developing countries but its thrombogenic tendency is not well-studied and established yet. Pulmonary embolism is rarely reported in Mycobacterium tuberculosis infection. There are reports stating the relation of pulmonary embolism (PE) and deep vein thrombosis (DVT) with a severe infection of tuberculosis but no data is available to establish a mutual association between pulmonary tuberculosis and pulmonary thromboembolism. Herein, we report the case of a 51-year-old male who presented with a one-month history of productive cough, shortness of breath, and fever associated with chills and night sweating. He reported an 8 kg weight loss in the last month. He was found to have pulmonary tuberculosis. On further investigations for leg swelling and tachycardia. Deep vein thrombosis and sub-massive saddle bilateral pulmonary embolism were diagnosed, which was treated with thrombolysis therapy (alteplase). He responded well to initial therapy and was discharged on anticoagulation with anti-tuberculous therapy (ATT).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
