There is a scarcity of research investigating the association between food allergy and AC. This retrospective cohort study aimed to determine the incidence of food allergy within AC patients and its linkage to disease intensity and to compare the response to sublingual immunotherapy after 4 months of therapy. The study included 240 individuals diagnosed with AC. Of these patients, only 214 (89.16%) cases exhibited positive skin prick test results and showed incidence of food allergy of 29.6 %. After 4 months of sublingual allergen immunotherapy, the total serum IgE level and the grades of severity decreased significantly (p 0.001 for each). On comparing patients with food allergy on sublingual immunotherapy and patients without food allergy and on sublingual immunotherapy, the change in total serum IgE concentration and the grade of severity did not differ among the two groups (p value was 0.63 and 1.00 respectively).

The link between oral lichen planus (LP) and CD was revealed, but there is currently no information available regarding the association between cutaneous LP and gluten sensitivity. This study aimed to assess the AGA (IgA and IgG) serum levels in LP patients compared to controls and to determine their correlation with LP severity. The study included 20 patients with cutaneous LP and 20 age- and sex-matched controls, both free of CD manifestations. The enzyme-linked immunosorbent assay (ELISA) technique was utilized for the evaluation of AGA (IgA and IgG) serum levels. Hepatitis C virus (HCV) antibodies in LP patients were evaluated qualitatively using a chromatographic immunoassay. In LP patients, AGA (IgA and IgG) serum levels were significantly elevated compared to controls (p = 0.015 and p=0.016, respectively). A significant positive correlation between AGA (IgG) serum levels and the age of patients (p= 0.024), duration of disease (p= 0.02), and LP severity index (p< 0.0001) was found. AGA serum levels were insignificantly different between HCV-positive and HCV-negative LP patients (p= 0.054).

The use of NSAIDs is essential in the Abidjan school because of the absence of therapeutic alternatives in the management of the inflammatory crisis of this disease. The induction of tolerance to NSAIDs initiated by the authors has had clear clinical success. The basic biological reasons for this tolerance were evaluated in this study. A group of 11 sickle cell patients aged 12 to 39 years in whom post-NSAID respiratory manifestations disappeared for at least 6 months following a short tolerance induction protocol with ibuprofen, was assayed by ELISA for TNFα, INFg (Th1 cytokines), IL-4 (Th2 cytokine), IL-10, TGF-β (immunosuppressive cytokines) and total IgE, before induction or pre-induction (D-1) and at day one (D1), D2- 3, one month (M1), and M6 after induction. A repolarization of the Th1/Th2 balance was noted during the post induction period. The high concentration of IL-4 observed at D-1 gradually decreased in favor of the cytokines TNFα, INFg. The decrease in cytokine IL-4 with the level of total IgE was accompanied by the increase of IL-10 and TGF-β demonstrating the regulatory role of these cytokines in the control of allergic diseases. In conclusion, the induction of immuno-tolerance to NSAIDs through a short protocol is well supported by immune regulation. The medium-term effects are real, unlike the results of allergen desensitization or specific immunotherapy. However, this protocol could be used in certain circumstances such as in the case of intolerance to trimethoprim-sulfamethoxazole, used as the treatment of choice for the prevention of opportunistic diseases in people living with human immunodeficiency virus.","PeriodicalId":39724,"journal":{"name":"The Egyptian journal of immunology / Egyptian Association of Immunologists","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135605690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to accurately determine the extent of the pandemic, it is important to accurately identify the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among healthcare workers (HCWs). This study intended to determine the prevalence of SARS-CoV-2 infection among HCWs and examine its correlation with the demographic characteristics of the study participants prior to the implementation of the vaccination campaign. In this cross-sectional study included 431 HCWs from Suez Canal University Hospital in Ismailia, Egypt. Their sera were screened for SARS-CoV-2 antibodies using a one-step novel coronavirus (COVID-19) IgM/IgG antibody test from Artron, Canada. Positive cases were then confirmed using nasal swab real-time reverse transcriptase PCR from Viasure, Spain. Of the 431 study participants, 254 (58.9%) were males and 177 (41.1%) females. The majority of participants, 262 (60.8%), were younger than 30 years old, 150 (34.8%) between 30 and 40 years old, and only 19 (4.4%) older than 40 years old. Out of the total samples, 26 (6%) tested positive for SARS-CoV-2 IgM, while 19 (4.4%) tested positive for both IgM and IgG.

This was a cross sectional study that included 108 active RA patients who were receiving csDMARDs. A detailed history was reviewed for all patients in addition to a complete physical examination and assessment of the 28-joint disease activity score (DAS28). Some laboratory measures were recorded as C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and serum rheumatoid factor (RF). Quantitative real-time polymerase chain reaction (qRT-PCR) was used to measure expression levels of TNF- α and IL-6 genes. In active RA patients, TNF-α and IL-6 genes expression levels were significantly correlated to each other (p<0.001, r=0.788). Also, both had positive correlations with the age and DAS28 among RA patients (p<0.001). IL-6 and TNF-α expression levels were significantly higher in RA patients with high DAS28 scores (p<0.001). Most RA patients (81.5%) had relatively higher IL-6 gene expression levels than TNF-α. RA patients with relatively high IL-6 expression levels were younger in age and had shorter disease duration and less DAS28 than RA patients with relatively high TNF-α gene expression levels. In addition, they had higher CRP and RF levels. Young age was detected as a significant predictor for relatively higher IL-6 gene expression levels than TNF-α.
