1/48. Markedly high eosinophilia and an elevated serum IL-5 level in an infant with cow milk allergy.BACKGROUND: interleukin-5 (IL-5) promotes the production and function of eosinophils, and an increase in the serum soluble CD23 (sCD23) level is suggestive of enhanced type-2 helper T-cell activity. The secretion of a large amount of the proinflammatory cytokine, tumor necrosis factor alpha (TNF-a), has been reported to alter the intestinal barrier capacity. OBJECTIVE: To determine whether or not distinct profiles of cytokine production were involved in the marked peripheral eosinophilia of as high as 20,000/mm3 and the gastrointestinal symptoms seen in an infant with cow milk allergy. methods: The levels of IL-5, sCD23, and TNF-alpha in serum and the culture supernatants of mononuclear cells were compared with those in infants with anaphylaxis to cow milk and nonallergic infants. RESULTS: interleukin-5 was detected in the serum (19 pg/mL) but became undetectable after 2 weeks on a milk-free diet together with clinical remission. A kinetic decrease in the serum sCD23 level was also observed during the administration of a milk-free diet with improvement of the eosinophilia in 2 months. The TNF-alpha produced in vitro after stimulation with cow milk protein was not different from in controls. CONCLUSION: It seems likely that the allergic inflammation due to cow milk can induce marked eosinophilia with an associated increase in IL-5 production.- - - - - - - - - - ranking = 1keywords = allergy (Clic here for more details about this article) |
2/48. Glucocorticosteroid treatment for cerebrospinal fluid eosinophilia in a patient with ventriculoperitonial shunt.BACKGROUND: cerebrospinal fluid (CSF) eosinophilia commonly occurs in patients with ventriculoperitoneal (VP) shunts and is associated with shunt complications such as obstruction or infection. Glucocorticosteroids (GCS) are effective in reducing eosinophilia and eosinophils in skin, nasal mucosa, and airway epithelium. Effects of GCS on CSF eosinophils has not been reported. OBJECTIVE: To demonstrate glucocorticosteroid effects on the CSF eosinophil levels and to propose that GCS may be used as a therapeutic agent for CSF eosinophilia. RESULT: A case report of a patient with congenital hydrocephalus and a VP shunt developed CSF eosinophilia associated with latex allergy and shunt malfunction. Daily treatment with 2 mg/kg of methylprednisolone was associated with reduced peripheral eosinophilia and slightly reduced CSF eosinophil counts. pulse methylprednisolone, 15 mg/kg, was associated with complete reduction of CSF eosinophils and prolonged VP shunt survival. CONCLUSION: Systemic glucocorticosteroids effectively reduce CSF eosinophils. Glucocorticosteroids may be beneficial for treatment of CSF eosinophilia associated with VP shunt malfunction.- - - - - - - - - - ranking = 0.2keywords = allergy (Clic here for more details about this article) |
3/48. Drug induced chest pain-rare but important.pericarditis, usually viral in origin, is an infrequent cause of chest pain. pericarditis due to drug allergy is even less frequent and is thus rarely considered in the differential diagnosis. A case is reported of a woman who presented with severe chest pain, caused by minocycline induced pericarditis. Such allergy may be more common than reported. It is suggested that drug induced pericarditis should be included in the differential diagnosis of acute chest pain.- - - - - - - - - - ranking = 0.4keywords = allergy (Clic here for more details about this article) |
4/48. The spectrum of pediatric eosinophilic esophagitis beyond infancy: a clinical series of 30 children.OBJECTIVES: eosinophilic esophagitis, previously confused with esophageal inflammation due to gastroesophageal reflux, has recently begun to be distinguished from it. We undertook this analysis of our large series of children with the condition to clarify its spectrum: its presenting symptoms; its relation to allergy, respiratory disease, and reflux; its endoscopic and histological findings; and its diagnosis and therapy. methods: We analyzed the details of our clinical series of 30 children with eosinophilic esophagitis, defining it as > or =5 eosinophils per high power field in the distal esophageal epithelium. Retrospective chart review was supplemented by prospective, blinded, duplicate quantitative evaluation of histology specimens, and by telephone contact with some families to clarify subsequent course. Presentation and analysis of the series as a whole is preceded by a case illustrating a typical presentation with dysphagia and recurrent esophageal food impactions. RESULTS: Presenting symptoms encompass vomiting, pain, and dysphagia (some with impactions or strictures). Allergy, particularly food allergy, is an associated finding in most patients, and many have concomitant asthma or other chronic respiratory disease. A subtle granularity with furrows or rings is newly identified as the endoscopic herald of histological eosinophilic esophagitis. Histological characteristics include peripapillary or juxtaluminal eosinophil clustering in certain cases. association with eosinophilic gastroenteritis occurs, but is not common. Differentiation from gastroesophageal reflux disease is approached by analyzing eosinophil density and response to therapeutic trials. Therapy encompasses dietary elimination and anti-inflammatory pharmacotherapy. CONCLUSION: awareness of the spectrum of eosinophilic esophagitis should promote optimal diagnosis and treatment of this elusive entity, both in children and in adults.- - - - - - - - - - ranking = 0.4keywords = allergy (Clic here for more details about this article) |
5/48. Allergic reaction to gemfibrozil manifesting as eosinophilic gastroenteritis.Eosinophilic gastroenteritis (EGE) is a rare condition of unknown etiology characterized by eosinophilic infiltration of the gastrointestinal (GI) tract. Previous associations with a drug or food allergy, allergic rhinitis, atopic dermatitis, and elevated IgE levels suggest an atopic predisposition in the pathogenesis of this disorder. Diagnostic criteria are GI symptoms, eosinophilic infiltration proven by biopsy of the GI tract, and absence of parasitic infection. We describe a case of EGE manifested as an allergy to gemfibrozil.- - - - - - - - - - ranking = 0.4keywords = allergy (Clic here for more details about this article) |
6/48. Allergic eosinophilic gastroenteritis in a boy with congenital duodenal obstruction.Eosinophilic gastroenteritis (EG) is a rare allergy-related disease, especially in early childhood. We present the case of a 1 year 4 month old boy with congenital duodenal obstruction who developed EG. That diagnosis of EG was made by a series of imaging studies and was confirmed by upper gastrointestinal (UGI) endoscopic biopsy studies which showed significant tissue eosinophilia in both mucosal and submucosal layers. No evidence of parasite segment or ova was found in the stool and biopsy specimen. Specific IgE antibodies to milk were estimated to be 2 (CAP system). Cow's milk allergy was highly suspected but not confirmed by consecutive elimination and challenge tests since the child was too much suffered to be tested. There was partial response to the 2-week treatment with Alfare (semi-elemental formula) and oral prednisolone 1 mg/kg/day. One month after initial examination, perforation of the stomach occurred and exploratory laparotomy disclosed stenosis of the duodenum. Congenital duodenal obstruction was diagnosed based on operative findings and previous sonographic findings. There has been only one report of EG in an infant with congenital duodenal obstruction. The nature of the relationships among cow's milk allergy as a possible etiologic factor, congenital duodenal obstruction as an predisposing factor and EG involvement at both mucosal and submucosal layers remains unclear.- - - - - - - - - - ranking = 0.6keywords = allergy (Clic here for more details about this article) |
7/48. life-threatening eosinophilic pleuropericardial effusion related to vitamins B5 and H.OBJECTIVE: To report a case of eosinophilic pleuropericarditis resulting from concomitant use of vitamins B5 and H. CASE SUMMARY: A 76-year-old white woman was admitted to the hospital because of chest pain and dyspnea related to pleurisy and a pericardial tamponade. This patient had no history of allergy and had been taking vitamins B5 and H for two months. blood tests performed showed an inflammatory syndrome and a high eosinophil concentration (1200-1500 cells/mm3). Pleurocentesis and pericardiotomy yielded a sterile exudative fluid with an eosinophilic infiltrate. There were no nuclear antibodies and no rheumatic factor; screenings for viruses, parasites, bacteria, and malignant tumor were negative. A myelogram, biopsy of the iliac crest bone, and concentration of immunoglobulin e were also normal. After withdrawal of the vitamins, the patient recovered and the eosinophilia disappeared. DISCUSSION: Prolonged hypereosinophilia has marked predilection to damage specific organs, including the heart, but pleuropericardial effusion is uncommon. Drug-related pleuropericarditis usually occurs without an increased eosinophil count. Other drugs responsible for eosinophilic pleuropericarditis are cephalosporins, dantrolene, propylthiouracil, and nitrofurantoin. To our knowledge, this is the first case report of pleuropericarditis related to vitamins B5 and H. CONCLUSIONS: This case suggests that vitamins B5 and H may cause symptomatic, life-threatening, eosinophilic pleuropericarditis. physicians prescribing these commonly used vitamins should be aware of this potential adverse reaction.- - - - - - - - - - ranking = 0.2keywords = allergy (Clic here for more details about this article) |
8/48. Immediate-Type allergy against human insulin associated with marked eosinophilia in type 2 diabetic patient.We describe a type 2 diabetic patient who showed immediate-type allergy against human insulin associated with marked eosinophilia at initial insulin therapy. Three months after initiation of insulin therapy, he noticed itchy skin wheals at the site of the insulin injection. Laboratory data at that time showed marked eosinophilia (2,512 /mm3) and progression of renal dysfunction. skin test with semisynthetic human insulin and protamine sulfate resulted in local immediate skin reactions such as itchy erythema and wheals. Histopathology of the biopsy specimen from skin showed perivascular infiltration of lymphocytes and numerous eosinophils in the dermis and subcutaneous fat. Although the titer of total IgE antibody was within normal range, that of insulin-specific IgE antibody was high. insulin administration was discontinued to preserve his insulin secretion, and stable control of his hyperglycemia was obtained by initiating nateglinide treatment (360 mg/day). His itchy skin lesions disappeared within two weeks after cessation of the insulin therapy and both eosinophilia and renal dysfunction gradually improved. Although the widespread use of human insulin in diabetic patients has greatly reduced the incidence of insulin allergy, the possibility of human insulin allergy should be kept in mind when initiating such therapy.- - - - - - - - - - ranking = 1.4keywords = allergy (Clic here for more details about this article) |
9/48. Acute myocarditis with transient eosinophilia and serum hyper-IgE-emia in a patient with atopic dermatitis.A 14-year-old girl with acute myocarditis, transient eosinophilia, and hyper-IgE-emia associated with atopic dermatitis is described. The patient was admitted because of severe heart failure and shock, and severe atopic dermatitis was seen. blood examinations showed moderate eosinophilia (1917/mm3) and hyper-IgE-emia (830IU/ml). The response to treatment with dopamine was excellent, and the congestive heart failure was gradually ameliorated, followed by improvement in her atopic dermatitis. In addition, rapid improvement in eosinophilia and hyper-IgE-emia was observed. Histopathological examination of the right ventricular myocardium obtained by endomyocardial biopsy showed mild interstitial fibrosis and mild infiltrations of inflammatory cells, indicating myocarditis. We speculated that the transient eosinophilia and hyper-IgE-emia in the present case indicated that an allergen induced strong allergic reactions, including type 1 allergy, and caused both acute myocarditis and deterioration of the atopic dermatitis; specifically noteworthy is that the patient's disease rapidly improved without corticosteroid treatment.- - - - - - - - - - ranking = 0.2keywords = allergy (Clic here for more details about this article) |
10/48. cephalexin-related nephropathy.hematuria and eosinophilia developed in two patients being treated for bacterial endocarditis with 20 or 24 gm/day of cephalexin given orally together with probenecid (Benemid). One patient had a concurrent transient increase in serum creatinine; both patients had a history of penicillin allergy and had previously received cephalexin intravenously. All abnormalities promptly remitted following discontinuation of therapy.- - - - - - - - - - ranking = 0.2keywords = allergy (Clic here for more details about this article) |
