There is no concurrent pruritus, urticaria, coughing, nausea, throwing up, diarrhea, abdominal discomfort, chest discomfort, lightheadedness, or lack of consciousness. No fevers had been acquired by him, chills, evening sweats, or fat loss. He’d take occasional non-steroidal anti-inflammatory medications for gout, while not lately. Home medicines included amlodipine, aspirin, metoprolol, and simvastatin. He experienced one bout of cosmetic angioedema with angiotensin-converting enzyme inhibitor make use of 20 years previously, which solved with medicine cessation. A month before presentation, the individual acquired isolated lip angioedema related to chlorthalidone; the medicine was stopped UAMC 00039 dihydrochloride as well as the swelling resolved. He had no other history of swelling, abdominal pain, or urticaria. PHYSICAL EXAMINATION The patient’s vital indicators included a heat of 36.4 C, blood pressure 110/61 mm hg, heart rate 51 beats/minute, and respiratory rate 12 breaths/minute. There was nonpitting angioedema of the lips, face, and tongue (Fig. 1). The lungs were obvious to auscultation, without wheezing; heart rate was bradycardic but regular; and the stomach was without masses or hepatosplenomegaly. There was no urticaria on skin examination. The rest of the examination was unremarkable. Open in a separate window Physique 1. An example of the patient’s lip swelling. INITIAL LABORATORY AND DIAGNOSTIC FINDINGS Laboratory analysis exhibited a hemoglobin of 16.5 g/dL (normal range, 13.5C17 g/dL), platelets were 222,000/mm3 (normal range, 150,000C400,000/mm3), and white blood cell count was 7700/mm3 (4000C10,000/mm3). The differential included neutrophils, 4100/mm3; lymphocytes, 2600/mm3; monocytes, 500 cells/mm3; and eosinophils, 400 cells/mm3 (all normal). Results of the patient’s chemistries showed a creatinine level of 0.93 mg/dL (normal range, 0.7C1.3 mg/dL), blood urea nitrogen level of 13 mg/dL (normal range, 8C20 mg/dL), and albumin level of 3.4 g/dL (normal range, 3.43C4.84 g/dL). The patient UAMC 00039 dihydrochloride received epinephrine, antihistamines, and intravenous glucocorticoids without effect. A fiberoptic laryngoscopy showed sparing of the larynx, with unremarkable glottic and supraglottic structures. Due to significant oropharyngeal UAMC 00039 dihydrochloride swelling, the patient underwent intubation. A further laboratory workup was performed. Match component 4 (C4) was 25 mg/dL (normal range, 13C60 mg/dL), match component 1q (C1q) was 20 mg/dL (normal range, 12C22 mg/dL), C1 esterase inhibitor function was 90% of normal, and C1 esterase inhibitor antigen was 36 mg/dL (normal range, 13C37 mg/dL). His immunoglobulin G (IgG) level was 1080 mg/dL (normal range, 620-1520 mg/dL), IgA level of 274 mg/dL (normal range, 40C350 mg/dL), and IgM level of 109 mg/dL (normal range, 50C370 mg/dL). The tryptase level was 3.9 ng/mL (normal value, 11.4 ng/mL). A serum protein electrophoresis with immunofixation showed no M-protein. The prostate specific antigen was 4.2 ng/mL (normal range, 0C6.5 ng/mL), consistent with the patient’s known biochemical recurrence and stable over the years. The patient’s swelling improved over 2 days, and he was successfully extubated. It was requested that unnecessary medications be halted; simvastatin and aspirin were discontinued. He was discharged on cetirizine 10 mg daily. QUESTIONS What Is the Differential Diagnosis of the Patient’s Angioedema? Angioedema denotes self-limited swelling that occurs from extravasation of fluids.1,2 Angioedema occurs during anaphylaxis, with acute and/or chronic urticaria, or in isolation. Angioedema is typically asymmetric, with onset of moments to hours and resolution of hours to days; is not gravity dependent (usually affecting the face, larynx, upper extremities, bowels, and genitals); and is nonpitting.2 The differential diagnosis includes histamine- and bradykinin-related angioedema.2,3 Anaphylaxis may occur due to foods, medications, insect stings, mastocytosis, or other causes; anaphylaxis is typically associated with additional symptoms and has a quick onset and resolution.2,3 Chronic urticaria is often idiopathic or related to autoimmune thyroid and rheumatologic diseases. 3 Bradykinin-related angioedema typically does not include other symptoms; causes include hereditary angioedema (HAE), acquired angioedema (often associated with neoplasms, including lymphoma),.
