Serum Levels of Vascular Endothelial Growth Factor, Platelet Activating Factor and Eosinophil-Derived Neurotoxin in Chronic Spontaneous Urticaria—A Pilot Study in Adult Patients. Int J Mol Sci 2022; 23:ijms23179631.

Abstract
Chronic spontaneous urticaria (CSU) is a skin disease characterized by the presence of wheals, angioedema, or both for at least 6 weeks. Although, CSU is often regarded as autoimmune in nature, its etiology is not fully explained and interactions between various small molecules are still taken under account. The aim of this research was to investigate the mean serum concentration of vascular endothelial growth factor (VEGF), platelet activating factor (PAF), and eosinophil-derived neurotoxin (EDN) in relation to the disease activity and pruritus intensity in adult patients with CSU. Fifteen patients with CSU and 15 healthy subjects participated in this pilot study. Blood samples were taken to examine the mean serum levels of VEGF, PAF, and EDN by the enzyme-linked immunosorbent assay test (ELISA). The Urticaria Activity Score (UAS7) and The Visual Analogue Scale (VAS) were used to assess the disease activity and the pruritus intensity, respectively. Obtained results revealed that VEGF, PAF, and EDN concentrations were higher in patients with CSU compared with those of the control group, but only for VEGF it was statistically significant (p = 0.008). However, levels of all investigated cytokines were not significantly correlated neither with the disease activity nor with the pruritus intensity. Our results showed higher serum levels of VEGF, PAF, and EDN among CSU patients which may highlight a functional role of these cytokines in the disease’s pathogenesis. In contrast, VEGF, PAF, or EDN might not be useful to reflect the severity of symptoms.

Localized and Generalized Skin Adverse Drug Reactions to Nadroparin Calcium Injection in 6 Cases of Pregnant Women. JOURNAL OF HEALTHCARE ENGINEERING 2022; 2022:5622482. [PMID: 35463677 PMCID: PMC9033372 DOI: 10.1155/2022/5622482] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Revised: 03/17/2022] [Accepted: 03/24/2022] [Indexed: 11/30/2022]
Abstract
Background Despite the increasing number of skin adverse drug reactions caused by nadroparin calcium have been reported, mostly, little is known regarding of their details of clinical characteristics, especially for generalized skin adverse drug reactions. We sought to evaluate localized and generalized characteristics of the skin adverse drug reaction to nadroparin calcium injection in pregnant women. Methods A retrospective study was conducted on 6 pregnant women, who experienced localized and generalized skin adverse drug reactions during long-term nadroparin calcium injection. The patients' clinical and imaging information were retrieved from medical records. The skin prick test, patch test, and intradermal test were performed after they stopped lactation. Causality assessment of suspected adverse drug reactions was performed on these cases. Results The average total dose of nadroparin calcium injection in the 6 cases was 64.17 ± 22.66. Localized skin adverse drug reaction, manifested as erythema at the injection point, appeared after 47.5 ± 17.4 days of subcutaneous injection of nadroparin calcium. Generalized urticaria-like lesions, progressing from the injection site on the abdomen, appeared in 5.17 ± 3.60 days after the first appearance of localized reaction, while laboratory test results revealed essential peripheral blood eosinophilia. All rashes in the 6 cases subsided in 2–5 weeks after drug withdrawal. After delivery, 5 of 6 cases received complete skin tests to evaluate drug hypersensitivity. Results presented positive in the intradermal test within 7 days. Both the skin prick test and skin patch test were negative. Localized skin reactions and generalized urticaria-like adverse drug reactions were considered as definitely and probably caused by nadroparin calcium injection, respectively. Conclusion Subcutaneous injection of nadroparin calcium in pregnant women appears to be at risk of localized and generalized urticaria-like adverse drug reaction. It is important to follow up the pregnant woman during nadroparin calcium injection for evaluating adverse drug reactions. Timely detection of symptoms is pivotal in early diagnosis and treatment of adverse drug reactions.

Abstract
Introduction Eosinophilia may cause organ dysfunction, but an exact relation between eosinophil blood counts and adverse outcomes has not been described. The aim of the study is to associate in one model both normal and increased blood eosinophil counts to the subsequent development of common conditions in internal medicine, in which eosinophil granulocytes may play a role for the symptoms. Methods From the Copenhagen Primary Care Differential Count (CopDiff) Database, we identified 359,950 individuals with at least one differential cell count (DIFF) during 2000–2007. From these, one DIFF was randomly chosen. From the Danish National Patient Register we ascertained organ damage, within four years following the DIFF. Using multivariable logistic regression, odds ratios were calculated and adjusted for previous eosinophilia, sex, age, year, month, CRP and comorbid conditions. Results Risks for skin- and respiratory disease were increased from above the median eosinophil count of 0.16 × 109/l and reached a plateau around 1.0 × 109/l. Furthermore, risks of most outcomes also increased when the eosinophil count approached zero. Conclusions The observed U-shaped association with a plateau of risks around 1 × 109/l indicates that the risk for symptoms due to eosinophilia do not increase proportionate at higher counts. This study demonstrates for the first time that there is indeed an increased risk below median count of 0.16 × 109/l for an increased risk for the same manifestations. Clinically, it means that a normal or even low count of eosinophils do not rule out a risk for organ affection by eosinophils, and may contribute to explain, why patients may have normal eosinophil counts in e.g. asthma or allergy and still have symptoms from the lungs and skin, most likely explained by the extravasation of eosinophils. Blood eosinophilia may cause end-organ symptoms. An exact relation between eosinophil count and outcome has not been demonstrated. Eosinophil numbers correlate to organ damage even below the definition of eosinophilia. This association is U-shaped between organ manifestations and eosinophil count in blood. A plateau of risks is observed around 1 × 109/l.

Ann Dermatol Venereol 2012; 139:636-40. [PMID: 23122377 DOI: 10.1016/j.annder.2012.05.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2012] [Revised: 03/12/2012] [Accepted: 05/02/2012] [Indexed: 10/28/2022]
Abstract
BACKGROUND Hypereosinophilic syndrome (HES) is defined as an eosinophil count equal to or greater than 1.5 G/L for more than 6 months with organ damage (heart, nervous system, lung, etc) after the exclusion of other common causes of eosinophilia. A myeloproliferative variant of HES with FIP1L1-PDGFRα fusion gene inducing constitutive activation of a tyrosine kinase receptor has been characterized. We report a case in which the diagnosis was revealed by mucosal erosions and ulcerations. PATIENTS AND METHODS A 50-year-old man reported bipolar erosions. He presented with an erosion on the glans, an ulceration on the lower lip and mild dermographism. He had an eosinophil count of 7.5 G/L (n<0.7) and raised LDH at 520 IU/L (n<480). Screening for the usual causes of eosinophilia was negative. Histology of the labial ulceration showed a polymorphous inflammatory infiltrate containing eosinophils. A chest scan demonstrated a ground glass-like pulmonary infiltrate and broncho-alveolar lavage revealed eosinophilic alveolitis. The myelogram showed rich bone marrow with eosinophils. FIP1L1-PDGFRα fusion transcript was detected in the blood. Imatinib (Glivec(®)) was initiated and a favourable outcome was achieved within a few months and maintained after one year of treatment. DISCUSSION Cutaneous signs are frequent features of HES. They are polymorphous and include pruritis, erythematous rash and urticaria. Mucosal ulcerations are uncommon and appear more frequently with the myeloproliferative FIP1L1-PDGFRα-associated variant of HES. Early diagnosis allows the onset of a targeted treatment with imatinib that may prevent the apparition of organ damage.

Abstract
BACKGROUND/PURPOSE Increased IgE and eosinophil levels are frequently observed in cutaneous inflammation and are thought to provoke the occurrence of urticaria. However, the relationship of these factors with the disease duration of urticaria remains unclear. The aim of this study was to compare serum total IgE levels, specific IgE sensitization rates and eosinophil percentages between acute and chronic urticaria in children. METHODS A total of 165 patients (104 with acute and 61 with chronic urticaria) from a tertiary referral hospital were enrolled in this study. Serum levels of total IgE, prevalence of sensitization to food and aeroallergens and blood eosinophil percentages were compared by the disease duration of urticaria. RESULTS There were no statistical differences in total IgE production, positive sensitization to specific allergens and eosinophil percentages between the patients with acute and chronic urticaria. There is a higher prevalence of sensitization to aeroallergens than food allergens in children with urticaria. In terms of gender, males had significantly higher serum IgE levels than females. CONCLUSION Boys potentially have a higher serum IgE expression than girls children with urticaria. IgE levels and eosinophil percentages are not good indicators for a prolonged course of urticaria. The prevalence of sensitization to aeroallergens was significantly higher than that of food allergens in children with urticaria. Routine laboratory analysis for common allergens is not appropriate, and it could be a feasible approach to detect a predilection for atopy when respiratory infections are causative factors of urticaria occurrence.

Abstract
Eosinophilia is an important indicator of various neoplastic and nonneoplastic conditions. Depending on the underlying disease and mechanisms, eosinophil infiltration can lead to organ dysfunction, clinical symptoms, or both. During the past 2 decades, several different classifications of eosinophilic disorders and related syndromes have been proposed in various fields of medicine. Although criteria and definitions are, in part, overlapping, no global consensus has been presented to date. The Year 2011 Working Conference on Eosinophil Disorders and Syndromes was organized to update and refine the criteria and definitions for eosinophilic disorders and to merge prior classifications in a contemporary multidisciplinary schema. A panel of experts from the fields of immunology, allergy, hematology, and pathology contributed to this project. The expert group agreed on unifying terminologies and criteria and a classification that delineates various forms of hypereosinophilia, including primary and secondary variants based on specific hematologic and immunologic conditions, and various forms of the hypereosinophilic syndrome. For patients in whom no underlying disease or hypereosinophilic syndrome is found, the term hypereosinophilia of undetermined significance is introduced. The proposed novel criteria, definitions, and terminologies should assist in daily practice, as well as in the preparation and conduct of clinical trials.

Abstract
Eosinophils may infiltrate the lung tissue, thus impairing gas exchange and causing several symptoms as dyspnea, fever, and cough. This process may be secondary to several factors, including drugs or parasite migration, or primary (idiopathic). Acute eosinophilic pneumonia is life-threatening and presents frequently in young smokers as an acute hypoxemic respiratory failure of generally less than a week with bilateral lung infiltrates, frequently misdiagnosed as severe community-acquired pneumonia. This patients present without peripheral eosinophilia but usually have more than 25% eosinophils on bronchoalveolar fluid. Chronic eosinophilic pneumonia is a protracted disease of usually more than a month before presentation, with a predilection for middle aged asthmatic patients. Hypoxemia is mild-moderate, and there are usually more than 1,000 eosinophils/mm3 of peripheral blood. Bronchoalveolar fluid has high eosinophil levels (usually more than 25%). Migratory peripheral infiltrates are seen in the chest x-ray film. Both acute and chronic eosinophilic pneumonia are treated by glucocorticoids and respiratory support as well as avoidance of any recognized trigger.

Abstract
SUMMARY Blastocystis is an unusual enteric protozoan parasite of humans and many animals. It has a worldwide distribution and is often the most commonly isolated organism in parasitological surveys. The parasite has been described since the early 1900s, but only in the last decade or so have there been significant advances in our understanding of Blastocystis biology. However, the pleomorphic nature of the parasite and the lack of standardization in techniques have led to confusion and, in some cases, misinterpretation of data. This has hindered laboratory diagnosis and efforts to understand its mode of reproduction, life cycle, prevalence, and pathogenesis. Accumulating epidemiological, in vivo, and in vitro data strongly suggest that Blastocystis is a pathogen. Many genotypes exist in nature, and recent observations indicate that humans are, in reality, hosts to numerous zoonotic genotypes. Such genetic diversity has led to a suggestion that previously conflicting observations on the pathogenesis of Blastocystis are due to pathogenic and nonpathogenic genotypes. Recent epidemiological, animal infection, and in vitro host-Blastocystis interaction studies suggest that this may indeed be the case. This review focuses on such recent advances and also provides updates on laboratory and clinical aspects of Blastocystis spp.

Abstract
Although commonly encountered in clinical practice, chronic urticaria (CU) remains difficult to treat. In contrast to acute urticaria, neither exogenous triggers nor specific immunoglobulin E are identified in most chronic cases. A body of evidence suggests that CU is represented within the spectrum of immune-mediated inflammatory diseases (IMID). Our understanding of the CU disease pathogenesis now recognizes a role for T cells, B cells, and autoantibodies, and intrinsic abnormalities of histamine-releasing effector cells, thus providing new targets of intervention beyond the current mainstay of often inadequate symptomatic treatment directed against histamine receptors and steroids, with their attendant morbidities. Agents previously used to treat other autoimmune and inflammatory diseases have demonstrated efficacy in CU. Newer biologic and nonbiologic immunomodulatory agents approved for other indications and in clinical development provide potential options for this often severe disease.

Abstract
BACKGROUND The non- or low-sedating H1 receptor antagonists represent the basic therapy for urticaria. OBJECTIVE To test an alternative approach to patients unresponsive to conventional treatment. MATERIALS AND METHODS A total of 22 patients with chronic urticaria unresponsive to conventional antihistamine treatment were enrolled for this study. They had uncontrolled urticaria even using multiple combinations of antihistamines on maximum doses and corticosteroids in short cycles (prednisone 20-40 mg, per os once a day, 3-7 days per month). Cutaneous biopsies of the urticaria lesions were taken. These findings were classified as: (I) a mixture of perivascular dermal inflammatory infiltrate composed of lymphocytes, monocytes and neutrophils and/or eosinophils; (II) inflammatory infiltrate composed chiefly of neutrophils; and (III) inflammatory infiltrate composed mainly of eosinophils. According to histology, the patients were submitted to one of the following therapeutic schemes: class A - antihistamine treatment plus dapsone; class B - colchicine or dapsone; class C - montelukast. RESULTS Four patients in class A, 08 in class B and seven in class C displayed complete control of urticaria after 12 weeks of treatment; one patient in class B and two in class C did not respond to treatment. Two years after discontinuation, 16 patients are still free of urticaria. CONCLUSIONS This study suggests an alternative approach for treating unresponsive chronic urticaria.
