Drug-associated acute lung injury: a population-based cohort study.

ABSTRACT: A number of drugs have been reported as risk factors for acute lung injury (ALI) and ARDS. However, evidence is largely limited to case reports, and there is a paucity of data on the incidence and outcome of drug-associated ALI (DALI).Using a population-based retrospective cohort study design, critically ill patients with a diagnosis of ALI were studied. These patients were classified as having DALI or non-DALI, based on whether they were exposed to prespecified drugs prior to development of ALI. Outcomes were compared between the two groups and frequencies and incidences reported.Among 514 patients with ALI, 49 (9.5%) had DALI with an estimated population-based incidence of 6.6 (95% CI, 4.8-8.5) per 100,000 person-years. Of the 49 patients with DALI,36 received chemotherapeutic/antiinflammatory agents, and 14 received amiodarone. Twelve patients had no additional risk factors for ALI (probable DALI), whereas 37 had alternative risk factors (possible DALI). Patients with and without DALI had similar baseline characteristics. However, the APACHE (Acute Physiology and Chronic Health Evaluation) III scores (median, 83 vs 70, P 5 .03), ICU mortality (35% vs 20%, P 5 .03), and hospital mortality (63% vs 32%, P , .001)were significantly higher in the DALI group compared with those of the non-DALI group. Hospital mortality remained significantly higher after adjusting for APACHE III score on admission and the presence of malignancy in logistic regression analysis (OR, 2.8; 95% CI, 1.3-6.4; P 5 .009).Drugs are important risk factors for ALI, and recognizing them as such may have important implications for early identification of patients at risk, discontinuation of the offending agent, and prognosis.

Project description:BackgroundPatients undergoing treatment for cancer are at increased risk of acute kidney injury (AKI). There are few data on AKI incidence and risk factors in the current era of cancer treatment.MethodsWe conducted a population-based study of all patients initiating systemic therapy (chemotherapy or targeted agents) for a new cancer diagnosis in Ontario, Canada (2007-2014). The primary outcome was hospitalization with AKI or acute dialysis. We estimated the cumulative incidence of AKI and fitted Fine and Gray models, adjusting for demographics, cancer characteristics, comorbidities, and coprescriptions. We modeled exposure to systemic therapy (the 90-day period following treatments) as a time-varying covariate. We also assessed temporal trends in annual AKI incidence.ResultsWe identified 163 071 patients initiating systemic therapy of whom 10 880 experienced AKI. The rate of AKI was 27 per 1000 person-years, with overall cumulative incidence of 9.3% (95% CI = 9.1% to 9.6%). Malignancies with the highest 5-year AKI incidence were myeloma (26.0%, 95% CI = 24.4% to 27.7%), bladder (19.0%, 95% CI = 17.6% to 20.5%), and leukemia (15.4%, 95% CI = 14.3% to 16.5%). Advanced cancer stage, chronic kidney disease, and diabetes were associated with increased risk of AKI (adjusted hazard ratios [aHR] = 1.41, 95% CI = 1.28 to 1.54; 1.80, 95% CI = 1.67 to 1.93; and 1.43, 95% CI = 1.37 to 1.50, respectively). In patients aged 66 years or older with universal drug benefits, diuretic, and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker coprescription was associated with higher AKI risk (aHR = 1.20, 95% CI = 1.14 to 1.28; 1.30, 95% CI = 1.23 to 1.38). AKI risk was further accentuated during the 90-day period following systemic therapy (aHR = 2.34, 95% CI = 2.24 to 2.45). The annual incidence of AKI increased from 18 to 52 per 1000 person-years between 2007 and 2014.ConclusionCancer-related AKI is common and associated with advanced stage, chronic kidney disease, diabetes, and concomitant receipt of diuretics or angiotensin-converting enzyme inhibitors/angiotensin receptor blockers. Risk is heightened in the 90 days after systemic therapy. Preventive strategies are needed to address the increasing burden of AKI in this population.

Project description:BackgroundRecent trends in the incidence of lung cancer have been reported despite the decreasing rate of smoking. Lung cancer is ranked among the top causes of cancer-related deaths. The ratio of adenocarcinoma to squamous cell carcinoma, as well as the ratio of women to men, is still increasing. Human papillomavirus (HPV) has been discovered in lung cancer tissues and blood specimens, particularly in Eastern countries. However, the association between HPV infection and lung adenocarcinoma remains unclear.MethodsThis population-based cohort study was conducted using data from Taiwan's single-payer national health insurance and cancer registry databases. Data on HPV infection, cancer, sex, age, comorbidities, urbanization, and occupation were collected. The cumulative incidence rates were generated using Kaplan-Meier curves and log-rank tests. COX regression analysis was used to estimate the hazard ratios of factors associated with cancer occurrence. We used data from 2007 and 2015. The cases were matched with sex and age in a 1:2 manner with 939,874 HPV+ and 1,879,748 HPV- individuals, respectively.ResultsThe adjusted hazard ratios [95% confidence interval (CI)] for HPV infection in all lung cancers were 1.539 (1.436-1.649), male lung cancer 1.434 (1.312-1.566), female lung cancer 1.742 (1.557-1.948), squamous cell carcinoma (SCC) 1.092 (0.903-1.320), male SCC 1.092 (0.903-1.320), female SCC 0.949 (0.773-1.164), adenocarcinoma 1.714 (1.572-1.870), male adenocarcinoma 1.646 (1.458-1.858), and female adenocarcinoma 1.646 (1.458-1.858). The highest adjusted hazard ratio for lung cancer was chronic obstructive pulmonary disease (COPD) 1.799 (1.613-2.007), followed by male sex 1.567 (1.451-6.863) and HPV infection. The highest adjusted hazard ratio for adenocarcinoma was HPV infection 1.714 (1.572-1.870), followed by COPD 1.300 (1.102-1.533), and for SCC, male sex 5.645 (4.43-3.37), followed by COPD 2.528 (2.002-3.192).ConclusionOur study showed that HPV infection was associated with the occurrence of adenocarcinoma of the lung in both men and women but was not associated with SCC of the lung.

Project description:Study objectiveTo estimate the incidence and relative risk of a hospitalization or emergency visit for noninfectious liver injury in users of eight oral antimicrobials-amoxicillin, amoxicillin-clavulanic acid, clarithromycin, cefuroxime, doxycycline, levofloxacin, moxifloxacin, telithromycin-compared with nonusers of these antimicrobials.DesignRetrospective, observational cohort study with a nested case-control analysis.Data sourceHealthCore Integrated Research Database.PatientsAdults with continuous health plan enrollment for at least 6 months before study entry who had a new dispensing of a study antimicrobial between July 1, 2001, and March 31, 2009. Cases had diagnoses indicating noninfectious liver injury during follow-up. To control for potentially confounding risk factors, 10 controls at risk for liver injury during follow-up were matched to each case by age, sex, and event date (liver injury date of the case), and analyses were adjusted for medical history, concomitant drugs, and health care service use.Measurements and main resultsTwo physician reviewers (blind to exposure) validated the cases. Among 1.3 million antimicrobial users, we identified 607 cases of liver injury, including 82 cases of severe hepatocellular injury and 11 cases of liver failure. Liver injury incidence in nonusers of study antimicrobials was 35/100,000 person-years (95% confidence interval [CI] 29-42/100,000 person-years). For valid cases, the adjusted relative risk among current users of multiple antimicrobials was 3.2 (95% CI 1.6-6.7). Levofloxacin had the highest relative risk for current single use (3.2, 95% CI 1.8-5.8). Relative risks were also elevated for amoxicillin-clavulanic acid (2.5, 95% CI 1.3-5.0), doxycycline (2.5, 95% CI 1.2-5.2), moxifloxacin (2.3, 95% CI 1.1-4.7), and amoxicillin (2.3, 95% CI 1.1-4.7).ConclusionThe results support a comparatively high adjusted relative risk of liver injury among patients exposed concurrently to multiple antimicrobials and modest elevations in the risk for several antimicrobials used alone; however, we found little evidence of any strong effect of commonly used antimicrobials on the risk of liver injury.
