In contrast to adaptive immunity and to certain components of innate immunity, only little is known on the influence of the complement system on cancer suppression and promotion . The lectin pathway of complement activation is an important part of innate immunity. It is mainly involved in opsonisation and lysis of pathogens and in recruitment of inflammatory cells. Our study aimed to assess the relationship between MASP-2 serum levels before and after chemotherapy in Syrian children with acute lymphoblastic leukemia, aiming to find a relation, which serve in early forecast of patients response to chemotherapy, where the study has been done at Children University Hospital in damascus between 2013-2014. This study included 37 children diagnosed with acute lymphoblastic leukemia (ALL). The levels of Mannose-Binding Lectin-associated Serine Protease-2 (MASP-2) were determined by Enzyme Linked Immuno Sorbent Assay (ELISA). The result was that serum levels of MASP-2 was strongly reduced after chemotherapy in children with acute lymphoblastic leukemia, and a strong correlation between serum marker levels before and after chemotherapy was found.

Research summary
تتناول هذه الدراسة مستويات MASP-2 المصليّة عند أطفال سوريين مصابين بابيضاض الدم اللمفاوي الحاد (ALL) قبل وبعد المعالجة الكيميائية. تهدف الدراسة إلى تقييم العلاقة بين مستويات MASP-2 المصليّة واستجابة المرضى للمعالجة الكيميائية. أجريت الدراسة في مستشفى الأطفال الجامعي بدمشق بين عامي 2013 و2014 وشملت 37 طفلاً. تم قياس مستويات MASP-2 باستخدام تقنية ELISA. أظهرت النتائج انخفاضاً ملحوظاً في مستويات MASP-2 بعد المعالجة الكيميائية، مما يشير إلى أن MASP-2 يمكن أن يكون عاملاً تنبؤياً لاستجابة المعالجة الكيميائية عند مرضى ابيضاض الدم اللمفاوي الحاد.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة في فهم العلاقة بين مستويات MASP-2 المصليّة واستجابة المعالجة الكيميائية عند الأطفال المصابين بابيضاض الدم اللمفاوي الحاد. ومع ذلك، يمكن توجيه بعض النقد البنّاء للدراسة. أولاً، حجم العينة صغير نسبياً (37 طفلاً)، مما قد يؤثر على تعميم النتائج. ثانياً، لم تتناول الدراسة تأثير العوامل الأخرى مثل الحالة الصحية العامة للأطفال أو العلاجات الأخرى التي قد تؤثر على مستويات MASP-2. وأخيراً، كان من الممكن تضمين مجموعة مقارنة من الأطفال الأصحاء لتعزيز النتائج.
Questions related to the research
  1. ما هو الهدف الرئيسي من الدراسة؟

    الهدف الرئيسي من الدراسة هو تقييم العلاقة بين مستويات MASP-2 المصليّة واستجابة المرضى للمعالجة الكيميائية عند الأطفال المصابين بابيضاض الدم اللمفاوي الحاد.

  2. ما هي التقنية المستخدمة لقياس مستويات MASP-2 المصليّة؟

    تم استخدام تقنية الممتز المناعي المربّط بالإنزيم (ELISA) لقياس مستويات MASP-2 المصليّة.

  3. ما هي النتائج الرئيسية التي توصلت إليها الدراسة؟

    أظهرت النتائج أن مستويات MASP-2 المصليّة انخفضت بشكل ملحوظ بعد المعالجة الكيميائية، مما يشير إلى وجود علاقة قوية بين مستويات MASP-2 واستجابة المعالجة الكيميائية.

  4. ما هي الانتقادات الممكنة للدراسة؟

    من الانتقادات الممكنة: حجم العينة الصغير، عدم تناول تأثير العوامل الأخرى، وعدم تضمين مجموعة مقارنة من الأطفال الأصحاء.

Chemotherapy causes neutropenia and increase susceptibility to infections. Morbidity and mortality due to infections remain serious problem in children with cancer. Decreased serum levels of Mannose-binding lectin ( MBL) may represent a risk factor f or infections in children with acute lymphoblastic leukemia receiving chemotherapy. The aim of this study was to determine whether low MBL levels is associated with increased risk of infections in Syrian children with acute lymphoblastic leukemia. The study has been done at Children University Hospital in Damascus between 2013-2014. This study included 37 children diagnosed with acute lymphoblastic leukemia (ALL) who were candidates for chemotherapy, and the infections were identified depending on patients files. The levels of Mannose-Binding Lectin (MBL) was determined by Enzyme Linked Immuno Sorbent Assay (ELISA). The result was that MBL serum levels are higher in patients who did not develop infections compared to patients who developed infections, and all patients with low MBL levels developed infections in contrast to patients with normal MBL serum levels.
This study aimed to investigate the validity of measuring IGFBP-3 in the serum of Syrian children with acute lymphoblastic leukemia (ALL) as additional markers in diagnosis and follow-up of the disease.
Our study aimed to evaluating significance of survivin as a prognostic marker of relapse in children with acute lymphoblastic leukemia. The study included 46 child (30 males, 16 females): 24 child with ALL at 35 day from BFM 95 Protocol and 22 rel apse child with ALL.
Serglycin is an intracellular proteoglycan in hematopoietic cells. It has been studied in normal and tumor hematopoietic cell, so it was suggested to have an important role in immunity and cancers as leukemia. The challenge to make a diagnosis for acute leukemia and to differentiate between myeloid or lymphoblastic leukemia, is the reason we go to assay concentration of serglyc in normal people and patient with acute myeloid leukemia and acute lymphoblastic leukemia from children and adult at hematology department in the main hospitals in Damascus ( Pediatric’shopital, Almouasat and Al asaad hospital) before beginning any kind of treatment and studying the relation with white blood cells count. We found clear difference between the concentration in patient with acute leukemia and normal people. There was a high level of this marker in paint with AML in contrast with ALL patients. We found a relation between concentration of serglycin and the count of white blood cells.
Relapse of acute lymphoblastic leukemia (ALL) in the central nervous system (CNS) in adults is considered a poor prognostic feature. Few reports have analyzed this issue. The objective of this study was to estimate the experience with CNS recurrence in adult patients with ALL, then to choose the best therapy.
