The spectrum of patients’ profile of JIA showed many similarities and differences among different populations. Therefore, our study aimed to analyze the clinical data, laboratory data, treatment protocols and patient’s outcomes of JIA among Egyptian population. Methods: We checked and analyzed medical files of children with JIA followed up at pediatric rheumatology clinic between 2004-2010 at Alexandria Main Children Hospital. Results: Our study included data about 63 Egyptian JIA patients (33 males and 30 females), with a mean age of 7.3±3.1 years (range 3-16 years). We found that oligoarticular subtype was the predominant (41.2%) among cases followed by polyarticular (35%) then systemic onset type in (23.8%). Most of the patients lived in rural areas (57.1%). Clinically, knee joints (74.6%) were the most affected joints while pallor (42.9%) was main extra-articular manifestations (42.2%) among all subtypes. Uveitis (6.3%) manifested among oligoarticular and polyarticular subtypes only. Rheumatoid factor and anti-nuclear antibody (ANA) were positive among 69.8% and 20.6% of the studied cases respectively. Remission rate was 47.6% and occurred mostly in oligoarticular subtype. Also, the regimen of combination of two drugs showed the highest remission rate (39.8%).

Reports showed that obese children are more liable to infection than lean ones; it was claimed that obese subjects have altered peripheral blood total lymphocyte counts in addition to reduced lymphocyte proliferative response to mitogen stimulation as well as dysregulated cytokine expression. Objective: This study aimed to evaluate the effect of childhood obesity on cell mediated immunity as indicated by peripheral blood lymphocyte phenotyping. Methods: We enrolled 30 school-aged children (mean age 10±3.27 years). They comprised two groups; 20 obese children with a mean body mass index (BMI) of 39.2± 12.5 and 10 matched control subjects with mean BMI of 18.4± 1.9. They were subjected to detailed anthropometric evaluation including weight, height, and waist hip ratio in addition to calculation of BMI, complete blood counting, and flow cytometric assessment of T-helper (CD4), T-cytotoxic/suppressor (CD8), and natural killer (CD56) cell counts . Results : The absolute lymphocyte (CD3) and natural killer cell (CD56) counts were comparable in both groups. However, the CD4%, CD8%, CD4/CD8 ratio were significantly lower in the obese children ( p =0.02, 0.03, 0.015 respectively).

We sought to investigate the expression of regulatory NK cells (CD56+CD16+CD158+) in atopic children with bronchial asthma in order to outline the value of these cells as biomarkers of disease severity and/or control. Methods: A cross sectional controlled study was carried out in the Pediatric Allergy and Immunology Unit, Ain Shams University. The study included 45 atopic children [mean age(SD)= (2.9) years] with bronchial asthma (BA) and/or allergic rhinitis (AR)as well as 40 healthy matched controls. Enrolled subjects underwent complete blood counting and flow cytometric measurement of NK cell (CD16+ CD56+) and regulatory NK cells (CD16+CD56+CD158+). Results: Patients had significantly higher regulatory NK cell percentages [mean (SD)= 41 (52) %] than controls [mean (SD)=15 (7.1)]; p ≤0.001. Regulatory NK cell counts and percentages did not vary with the concomitant presence of AR or the degree of asthma control. Regulatory NK cell counts tended to be higher in children with moderate/severe BA compared to those with mild asthma but the difference did not reach statistical significance (U= -1.8, p=0.06). NK cell counts [mean (SD)= 159 (164) cells/μl] and percentages [mean (SD)= 3.7 (3.2) %] were comparable among patients and controls and did not vary with the presence of AR ( p = 0.51, 0.95) or with the degree of asthma control. NK cells absolute counts and percentages tended to be higher among patients with moderate/severe compared to mild asthma but the difference did not reach statistical significance.

The prevalence of CD in type-1 DM ranges from 0.6 to 16.4% compared with 0.01–0.03% in the general population. The mechanism of association between the two diseases involves a shared genetic background of HLA genotype. Serum tissue transglutaminase IgA antibodies (tTG IgA) are considered specific and sensitive markers for screening of Celiac disease in more than 95 % of patients. Objective: Screening for the presence of serum tissue transglutaminase IgA antibodies (tTG ab) as a specific and sensitive biochemical marker for Celiac disease in patients with type-1DM and its relation to the clinical manifestations of those patients. Methods: One hundred-forty-nine patients with type-1 DM attending the out-patient clinic of endocrine and metabolism, Minia University Hospital were screened for the presence of serum tissue transglutaminase IgA antibodies during the period from March 2014 to November 2015. Results: Out of 149 patients 8 patients (5.3%) were positive for IgA tTG antibodies. They who were predominantly of female gender (75% were females). According to each age group, there were four sero-positive cases in children (with age group between 9 and ≤ 12 years); two cases in adolescents (with age group between 12 and ≤ 16 years) and two cases in adults (with age group 16-21 years). Intestinal manifestations, chronic diarrhea, recurrent abdominal pain/ distension, recurrent aphtha's stomatitis, anemia and bleeding tendency were significantly more common in sero-positive cases (P=0.001, 0.001, 0.016, 0.00, 0.001and 0.04 respectively). All sero-positive cases (100%) had lower BMIs than normal. There were no correlations between the tTG antibodies levels and HbA1c levels. Conclusions: The presence of tTG IgA antibodies is associated with significant changes in the clinical status of patient with type-1 DM. Celiac disease related manifestations like weight loss; anemia and chronic diarrhea were more common in sero-positive diabetic patients.

The development of sensitive diagnostic polymerase chain reaction (PCR) based techniques permitted demonstration of an already clinically suspected association between common viral respiratory infections and asthma exacerbations. Respiratory viruses have been identified in 80–85% of exacerbations in school-aged children, with human rhinoviruses (HRVs) being the most frequently detected. A recently identified HRV genotype, HRV-C, is circulating worldwide and is an important cause of febrile wheeze and asthmatic exacerbations in children requiring hospitalization. Objectives: This study aimed to detect HRV- induced asthma exacerbations (including the new HRV-C genotype) among a group of Egyptian children. Methods: This cross-sectional study was conducted on 31 asthmatic children in exacerbations in the period from September 2014 till October 2015. Patients were recruited from the emergency department and chest clinic, Children's hospital, Ain Shams University. Sputum (for children ≥7years) and nasopharyngeal aspirates (for infants and children<7years) were collected for one-step, real-time pan Rhinovirus reverse transcription polymerase chain reaction (RT-PCR) assay. One step RT-PCR was done to detect Rhinovirus C among positive cases. Results: This study included 31 asthmatic children in exacerbations. They were 15 males (48.4%) and 16 females (51.6%). Their ages ranged from 7 months to 12 years with a mean and SD of (4.47 ± 3.15) years. Eight (25.8%) of the studied patients showed positive Rhinovirus RT-PCR test and 4 (50%) of the HRV positive patients were of the Rhinovirus C genotype (12.9% of the total population). HRV positive patients showed higher percentage of positive family history of bronchial asthma (p=0.002), higher mean values of respiratory rate (p=0.001) and temperature (p=0.001), but lower mean value of oxygen saturation (p =0.011). There were statistically significant differences regarding the exacerbation severity (p=0.024) and outcome (p=0.048) between HRV positive and negative patients. Conclusion: HRVs are important triggers of asthma exacerbations among Egyptian children. The newly described HRV-C genotype accounts for a significant proportion of HRV- associated asthma exacerbations.

To date, more than 150 defects have been identified and the number is growing. These disorders are broadly classified into defects affecting the humoral (B cell) immunity, defects of the cellular (T cell) immunity or both T cell and B cell, neutrophil and macrophage defects, and defects in the innate immunity. The hallmark clinical feature is recurrent and/or severe infections. However, some type of immune defect may present with autoimmune manifestations, and increased risk of malignancy in association with their underlying immunodeficiency. In PID diseases, the gastrointestinal (GI) tract is the second target organ affected after the respiratory tract. In fact, the GI is largest lymphoid organ in the body with a unique function to handle the process of regulation and suppression of foreign antigens including viruses, bacteria, parasites, and food. Therefore, in PID the dysfunction of the regulatory mechanisms that maintain the balance between active immunity and tolerance in the gut may lead to mucosal damage and chronic GI diseases. The GI manifestations in PIDs can be categorized into five different forms: (1) Infection throughout the GI tract or hepatobiliary system such as giardiasis in humoral immunodeficiency; cytomegalovirus colitis and hepatitis in severe T cell dysfunction as well as hepatic abscess in phagocytic defect. (2) Autoimmune phenomena such as autoimmune hepatitis and enteropathy that are associated with some PIDs and may mimic classic forms of diseases such as celiac disease (CD), inflammatory bowel disease (IBD), and pernicious anemia, but differ in pathogenesis and are often unresponsive to conventional therapies. (3) Unregulated inflammatory conditions such as granulomatous colitis in common variable immunodeficiency (CVID) and chronic granulomatous disease (CGD).
