Deep vein thrombosis is a common condition encounter by hospitalists and managed by either oral or intravenous anti-coagulation. Although uncommon, phlegmasia cerulea dolens (PCD) is a life-threatening manifestation of acute deep vein thrombosis requiring early recognition and aggressive intervention to preserve life and limb. PCD is characterized by marked swelling of the lower extremities with pain and cyanosis, which often leads to gangrene and amputation. We present the case of a patient who developed PCD of her left lower extremity who was successfully treated with an EkoSonic™ endovascular catheter (Boston Scientific, Marlborough, MA, USA), which accelerates lytic dispersion of the thrombolytic drug through ultrasound technology.
Use of nitrofurantoin for uncomplicated cystitis and recurrent urinary tract infections is common practice. While the majority of patients tolerate this medication without issue, it is important to be cognizant of adverse reactions, as these can impact patient's quality of life. Nitrofurantoin-induced pulmonary toxicity is a rare side effect that can present with various clinical manifestations, imaging abnormalities, and pathologic findings. We describe a case of chronic pneumonitis in a patient on suppressive nitrofurantoin therapy presenting with dyspnea and hypoxemia.
Background People living with HIV (PLHIV) have increased risk of cardiovascular disease (CVD), however CVD risk assessment can be challenging as HIV-related factors are not included in most calculators. We compared CVD risk calculators in US Military HIV Natural History Study (NHS) participants. Methods The NHS database was screened for participants enrolled between 2009-2019 who were ≥ 40 years of age with no previous history of CVD or statin use. Of the 399 participants meeting criteria, 385 (96.5%) had available data to assess 3 CVD risk calculators: Atherosclerotic CVD risk calculator (ASCVD), Framingham Risk Calculator (FRC), and the Data Collection on Adverse Effects of Anti-HIV Drugs Study (DAD) risk calculator. Risk calculators were applied cross-sectionally at the first available time point at or after age 40 years and calculators were compared using a Wilcoxon signed rank test. Demographic and HIV-related characteristics were analyzed as independent variables. Results Participants were predominantly male (91.1%), mostly White (49.6%) or Black/African American (44.7%), and commonly had a history of tobacco use (38.9%). The mean age at HIV diagnosis and at CVD risk calculation was 33 and 41.8 years, respectively (Table 1). Overall, there was significant variability between calculators with mean scores of 3.66%, 2.50% and 1.38% for ASCVD, FRC, and DAD, respectively for all pairwise comparisons (p< 0.001; Table 2). When assessing those with CVD risk ≥ 7.5%, a clinically relevant threshold, the proportion of individuals with risk ≥ 7.5% varied for the ASCVD (10.4%), FRC (7.5%), and DAD (< 0.8%) calculators. Associations or trends toward higher CVD risk was observed among the various calculators for race/ethnicity and both age < 30 years and CD4 ≤ 350 cells/uL at HIV diagnosis (Table 2). Conclusion Since significant variability among CVD risk calculators was observed in the NHS cohort, it may be challenging to apply overall CVD risk calculators in a clinically relevant manner. HIV-related factors, such as duration of HIV infection and CD4 nadir, are not accounted for in CVD calculators and may be indicators of increased CVD risk. Future studies are warranted in order to determine the optimal clinical use of CVD risk calculators for PLHIV. Disclosures All Authors: No reported disclosures
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.
