Asthma is the most common chronic disease in childhood, the incidence progresses and constitutes a public health problem which needs the research of factors that increase the incidence and severity of crisis, and among these factors IgG4 deficiency. Therefore the objective of the study is to know the effect of IgG4 deficiency on severity and evolution of asthma in children.

Research summary
تتناول الدراسة تأثير نقص الغلوبولين المناعي IgG4 على شدة وتطور الربو عند الأطفال. الربو هو أحد الأمراض المزمنة الأكثر شيوعاً في الطفولة، ويشكل مشكلة صحية عامة تتطلب البحث عن العوامل التي تزيد من نسبة حدوثه وشدة نوباته. أجريت الدراسة على 43 طفلاً يعانون من الربو ونقص في IgG4 في مركز الربو بمشفى تروسو الجامعي في باريس، وتم تقسيمهم إلى مجموعتين: ربو تحسسي وربو غير تحسسي. تمت متابعة تطور الربو لديهم لمدة تتراوح بين 18-24 شهراً، وتمت المقارنة مع مجموعة شاهد. أظهرت النتائج أن نسبة الربو التحسسي كانت أقل في مجموعة نقص IgG4 مقارنة بمجموعة الشاهد، وأن نسبة التطور غير المناسب للربو كانت أعلى في مجموعة نقص IgG4. خلصت الدراسة إلى أن نقص IgG4 يعتبر مؤشراً سيئاً لتطور الربو التحسسي وغير التحسسي عند الأطفال، ويمكن أن يكون له دور مسبب في إمراضية الربو. وأوصت الدراسة بإمكانية استخدام العلاج بالغاماغلوبولين لتحسين الإنذار.
Critical review
دراسة نقدية: تقدم الدراسة معلومات قيمة حول تأثير نقص IgG4 على تطور الربو عند الأطفال، ولكن هناك بعض النقاط التي تحتاج إلى توضيح. أولاً، حجم العينة صغير نسبياً، مما قد يؤثر على قوة النتائج والاستنتاجات. ثانياً، لم يتم توضيح ما إذا كانت هناك عوامل أخرى قد تؤثر على شدة الربو وتطوره، مثل العوامل البيئية أو الوراثية. ثالثاً، الدراسة تعتمد على متابعة لمدة محددة (18-24 شهراً)، وقد يكون من المفيد متابعة الأطفال لفترة أطول للحصول على نتائج أكثر دقة وشمولية. وأخيراً، يجب توضيح المزيد حول آلية تأثير نقص IgG4 على الربو وكيف يمكن للعلاج بالغاماغلوبولين أن يحسن الإنذار بشكل أكثر تفصيلاً.
Questions related to the research
  1. ما هو الهدف الرئيسي من الدراسة؟

    الهدف الرئيسي من الدراسة هو معرفة تأثير نقص IgG4 على شدة وتطور الربو عند الأطفال.

  2. ما هي النتائج الرئيسية التي توصلت إليها الدراسة؟

    النتائج الرئيسية هي أن نسبة الربو التحسسي كانت أقل في مجموعة نقص IgG4 مقارنة بمجموعة الشاهد، وأن نسبة التطور غير المناسب للربو كانت أعلى في مجموعة نقص IgG4.

  3. ما هي التوصيات التي قدمتها الدراسة؟

    أوصت الدراسة بإجراء معايرة للغلوبولينات المناعية وخاصة IgG4 في حالات الربو الشديد المعتمد على الكورتيزون، واستخدام العلاج بالغاماغلوبولين الوريدي لتحسين الإنذار.

  4. ما هي العوامل التي لم تأخذها الدراسة بعين الاعتبار والتي قد تؤثر على النتائج؟

    العوامل البيئية والوراثية لم تُذكر بشكل واضح في الدراسة، وقد تكون لها تأثير على شدة وتطور الربو.

Background& Objective: Selective IgA deficiency is the most common primary immunodeficiency in humans. Its prevalence ranges from 1 in 100 to 1 in 1000 in among Arab populations. The majority of patients with selective IgA deficiency are asymptomat ic. The remaining present with recurrent upper and lower respiratory tract infections, recurrent gastrointestinal infections, otitis media, sinusitis, celiac disease, giardiasis, allergic disorders and some autoimmune diseases. to highlight the clinical manifestations and laboratory findings of Selective IgA deficiency in our study, and to compare it with medical literature. To study the bacterial complications and their prevalence. Materials & Methods: A retrospective study was carried out in Damascus University Children’s Hospital on sixteen child diagnosed as Selective IgA deficiency, in a period of the last ten years (from 2000 till September 2010). Results: most cases in our study were among males, failure to thrive was found in 75%, hepatosplenomegaly in one third, the most prominent infectious complications were: recurrent pneumonia (in 87.5% of cases), recurrent GI infections (in 75% of cases) and UTI’s in (50%)of cases. On the other hand, the celiac disease was found in (25%) of our patients, which is much higher than described in medical literature. In general, the infectious complications had a good response to antibacterial therapy, and the IgA levels became normal in one patient, when he reached the age of eleven years. Conclusion: there is no information in medical literature about the association of selective IgA deficiency with hepatomegaly, splenomegaly, failure to thrive and an increased prevalence of urinary tract infections, therefore, it is necessary to conduct researches about this association.
This study was done to determine whether use of nebulized salbutamol therapy for treatment of an acute attack of asthma in children is associated with hypokalaemia and if so what is its frequency, severity and what is accompanying clinical symptoms 103 child, aged 3 years to 14 years with asthma attack, treated with three doses of nebulized salbutamol 0.15mg/kg, every 20 min participated in the study. Blood for serum potassium was obtained at the beginning and after three doses of nebulized salbutamol therapy.The mean serum potassium level decreased from 3.94 mEq/L to 3.28 mEq/L (P < 0.05). A decrease in serum potassium concentration was noted in 93 child (90.3%).). Mild hypokalemia formed the highest proportion in 43child (41.7%) followed by moderate hypokalemia in 28 child( 27.2%). Severe hypokalemia did not happen.This decrease was accompanied with clinical symptoms (palpitations 23,muscle weakness 21,nausea 15, headache 12,myalgia 11,vomiting 9).These symptoms were moreclosely to moderate hypokalemia.
Hyperimmunoglobulin E (Job) syndrome is considered to be a relatively rare disease. Its characterized by recurrent infections in skin (eg. boils, abscesses), recurrent upper respiratory tract infections (eg. otitis media, sinusitis and mastoiditis) , and lower respiratory infections (eg. recurrent pneumonia, which is often complicated by pneumatoceles and lung abscess), that are usually difficult to treat. The highly increased IgE levels are considered to be the hallmark of the disease. The syndrome has two types: one is inherited as an autosomal recessive, and the other, as an autosomal dominant trait. To highlight the clinical manifestations and laboratory findigs of Job disease, and to compare it with medical literature, to study the bacterial complications and differrent types of antibacterial treatments and treir results, and to increase the level of awareness among physicians.
the research performed by the ITP study group in 2006[15] studying the efficacy of single dose IV-Rhesus antibodies (Anti-D) "50 ug/kg or 75 ug/kg" compared to the single dose IVIG "800 mg/kg"; that study revealed that both have a similar therapeutic effect. that study suggest to compare the single high dose of Anti-D withthree consecutive doses of Methyl-prednisolone in respect of: 1- Time of platelet recovery 2- The continuity of mediation effect throughout ( 6 months) 3- Side effects, hospitalization and cost.
This study was conducted to investigate the relationship between estrogen depletion ,calcium-deficiency,and alveolar bone loss. Alveolar bone loss was evaluated by radiographic and visual inspection of rabbits with experimental lack of estrogen an d calcium. Twenty female local rabbits (4 months old) were divided into four groups :group a -ovariectomized and given a standard solid diet. Group b-ovariectomized and given a calcium – deficient diet Group c-sham-ovariectomized and given a standard solid diet. And group d-sham-ovariectomized and given a calcium-deficient diet after 8 weeks,the rabbits were sacrificed . The maxillae, mandibles, femurs, and tibias were removed carfully and fixed in 10% neutral buffered formalin. The bone mineral density of each bone and the alveolar bone loss were measured.the bone meniral densities of the maxillae,mandibles,femurs and tabias in group (c) were significantly higher than those in groups (b)and (d),but not higher than those in group a.however there were no significant differences between any of the groups with regard to alveolar bone loss from the cemento-enamel junction to the molar bone crest.
