Non-Hodgkin's lymphoma (NHL) is a common AIDS-defining malignancy among people living with HIV. Of the different types of NHLs, diffuse large B-cell lymphoma (DLBCL) is the most common. Prognosis of DLBCL has improved over the years in the general population but remains relatively poor in HIV-positive individuals. Almost any organ system can be affected by DLBCL; however, cardiac involvement remains rare and suggests aggressive disease. We present a case of DLBCL in an HIV-positive patient, who had cardiac involvement, with the only clue to cardiac involvement being symptom being tachycardia and dysphagia.
INTRODUCTION: Iron Deficiency Anemia (IDA) occurs in 2-5% of adults and requires workup including upper esophagogastroduodenoscopy (EGD) and/or colonoscopy.1 However, in 10-41% of patients a source of bleeding is not identified,2–5 which requires investigation of the small bowel using video capsule endoscopy (VCE). This study aims to determine the long-term outcomes in patients with IDA and a pan endoscopy-negative IDA, which entails negative EGD, colonoscopy and VCE. METHODS: Medical records at the VA NY Harbor were queried for patients with IDA and having an EGD, colonoscopy, and VCE between 2005-2015. Anemia was defined as hemoglobin less than 13 g/dL in men and 12 g/dL in women; IDA was confirmed using serum ferritin less than 100 ng/mL. Exclusion criteria included underlying causes for IDA such as pre-menopausal women or history of ulcerative colitis. Biographical, laboratory and endoscopic data were obtained. Baseline hemoglobin and ferritin levels were recorded, and subsequently followed at 1, 3, and 6-year intervals. RESULTS: A total of 7,000 records were reviewed, 311 patients had EGD, colonoscopy and VCE; 67 of these patients were excluded. Of the remaining patients, 99 patients (13 females, 86 males) had a negative initial workup and were included in analysis. The mean age was 68.2 (±11.1). IDA resolved in 37 (37.4%) patients, 49 (49.5%) patients had persistent anemia, and 13 (13.1%) patients had recurrent anemia. Of the 99 patients with negative workup, 80 (80.8%) patients went on to have subsequent EGD, colonoscopy or VCE. 62 (62.6%) patients had subsequent EGD with 12 (19.4%) patients having positive findings such as gastric ulcers. 64 (64.7%) patients had subsequent colonoscopies, 7 (10.9%) of these patients had positive findings such as chronically bleeding hemorrhoids. 18 (18.2%) patients had subsequent VCEs, and 5 (27.8%) of these patients had findings such as angioectasias. CONCLUSION: Our findings are consistent with previous reports suggesting that the majority of elderly patients who have an initial negative workup for IDA tend to have favorable outcomes. 21 of 80 patients (26.25%) had some findings on subsequent workup to explain IDA, however those findings were benign. In addition to previous published data, our study highlights the significance of VCE as a tool for identifying a bleeding source. Our study also emphasizes the need for randomized control studies to determine the optimal workup strategy for patients with initially negative bidirectional endoscopy and VCE.
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.
