Latar belakang: Leukemia limfoblastik akut (LLA) merupakan kanker tersering pada anak. Berbagai studi mendapatkan bahwa vitamin D berperan dalam pencegahan beberapa jenis kanker. Belum ada studi yang menilai hubungan status vitamin D dengan penyakit LLA pada anak di Indonesia. Tujuan: Untukmengetahui hubungan antara status vitamin D dengan penyakit LLA pada anak. Metode: Studi potong lintang pada 40 anak LLA yang baru terdiagnosis dan 40 anak sehat yang sesuai umur dan jenis kelamin. Pasien LLA diambil secara consecutive sampling di RSUPN Dr. Cipto Mangunkusumo Jakarta dan RSUP Dr. M. Djamil Padang. Status vitamin D diklasifikasikan berdasarkan rekomendasi Institute of Medicine yaitu defisiensi bila kadar < 12 ng/mL, insufisiensi 12 - <20 ng/mL, dan normal 20-100 ng/mL. Data dianalisa menggunakan uji Chi-Squaredan independent sample t-test, dengan kemaknaan p <0,05. Hasil: Terdapat 22 (55%) anak laki-laki pada masing-masing kelompok dan kelompok usia 1-4 tahun merupakan kelompok terbanyak (48%). Mayoritas anak LLA memiliki status vitamin D normal (78%), demikian juga kelompok kontrol (63%). Terdapat 3(7%) dan 6(15%) anak LLA serta 1(2%) dan 14(35%) anak sehat memiliki status defisiensi dan insufisiensi berturut-turut dengan p =0,14. Rerata kadar vitamin D anak LLA adalah 25,1(7,6) ng/mL dan anak sehat 21,9(5,67) ng/mL, dengan perbedaan rerata 3,14 (IK95% 0,15-6,13) dan p =0,04. Simpulan:Mayoritas anak LLA yang baru terdiagnosis memiliki status vitamin D normal. Rerata kadar vitamin D anak LLA lebih tinggi bermakna dari anak sehat, namun tidak terdapat hubungan yang bermakna antara status vitamin D dan penyakit LLA pada anak. ...... Background:Acute lymphoblastic leukemia (ALL) is the most common cancer in children. Various studies have found that vitamin D plays a role in the prevention of several types of cancer. Currently, there is no study in Indonesia that assess association between vitamin D status and pediatric ALL Objective:To determine association between vitamin D status and pediatric ALL. Methods:A cross-sectional study of 40 newly diagnosed ALL children and 40 age-and sex-matched healthy children. ALL patients were taken by consecutive sampling at Dr. Cipto Mangunkusumo Hospital Jakarta and Dr. M. Djamil Hospital Padang. Vitamin D status is classified based on Institute of Medicine recommendations; deficiency <12 ng/mL, insufficiency 12 - <20 ng/mL, and normal 20-100 ng/mL. Data were analyzed using Chi-square test and independent sample t-test. A p-value <0.05 is considered to be statistically significant. Results: There were 22 (55%) boys in each group and the group 1-4 years was the most age group (48%). Majority of ALL children had normal vitamin D status (78%) and also in healthy children (63%). There were 3(7%) and 6(15%) ALL children as well as 1(2%) and 14(35%) healthy children had deficiency and insufficiency status consecutively, with p value =0.14. The mean vitamin D level of ALL children and healthy children were 25.1 (7.6) ng/mL and was 21.9 (5.67) ng/mL consecutively, with mean difference of 3.14 (95% CI 0.15-6.13) and p value =0.04.. Conclusion:The majority of newly diagnosed ALL children have normal vitamin D status. The mean vitamin D levels of ALL children was significantly higher than healthy children, however there was no significant association between vitamin D status and ALL in children.

Latar belakang : Prevalens terjadinya malnutrisi bervariasi pada berbagai siklus kemoterapi LLA. Penelitian di Malaysia mendapatkan anak LLA pasca-kemoterapi fase induksi cenderung mengalami obesitas atau status gizi lebih. Penyebab malnutrisi pada anak LLA dapat dipengaruhi oleh berbagai faktor. Perubahan status gizi selama kemoterapi dapat memengaruhi luaran kemoterapi. Tujuan: mengetahui faktor-faktor yang memengaruhi perbaikan status gizi anak LLA setelah kemoterapi fase konsolidasi, serta pengaruhnya terhadap luaran kemoterapi, sehingga dapat dipakai sebagai masukan untuk upaya mengatasi malnutrisi pada anak LLA. Metode : Penelitian ini dengan uji retrospektif, di Rumah sakit Cipto Mangunkusumo, selama tahun 2016-2018. Total sampling pada pasien leukemia limfoblastik akut yang terdiagnosis, dan menjalani kemoterapi di RSCM hingga fase konsolidasi. Hasil : Seratus empat puluh satu subyek pasien anak LLA diikutsertakan dalam penelitian ini. Terdapat 69,5% subyek mengalami perbaikan status gizi, dan 30,5% mengalami perburukan status gizi, dengan 60% perburukan ke arah overnutrition pasca-kemoterapi fase konsolidasi. Faktor risiko independen terhadap terjadinya perbaikan status gizi pasca-kemoterapi fase konsolidasi ialah tidak timbulnya efek samping kemoterapi (RR 1,36, 95% IK 1,02 - 1,81). Jenis makanan dan cara pemberian makan tidak memengaruhi perubahan status gizi anak LLA pasca-fase konsolidasi. Terdapat hubungan antara perbaikan status gizi anak LLA pasca-fase konsolidasi dengan kejadian remisi (RR 1,24, 95% IK 1,03 - 1,5). Simpulan : Status gizi pasca-kemoterapi fase konsolidasi mengalami perbaikan dibandingkan sebelum kemoterapi, sedangkan yang mengalami perburukan status gizi cenderung mengalami overnutrition. Perbaikan status gizi anak LLA pasca-kemoterapi fase konsolidasi dipengaruhi oleh tidak timbulnya efek samping kemoterapi. Terdapat hubungan antara perbaikan status gizi anak LLA pasca-kemoterapi fase konsolidasi dengan kejadian remisi.

ABSTRACT
Background: Acute lymphoblastic leukemia (ALL) is the most common malignancy in childhood. The prevalence of malnutrition varies in phase of ALL chemotherapy. Study in Malaysia showed ALL children after induction phase of chemotherapy tended to be obese or overweight. The causes of malnutrition in ALL children can be influenced by various factors. Changes in nutritional status during chemotherapy can affect the outcome of chemotherapy. Aim: To investigate factors that influence nutritional status improvement of ALL children after consolidation phase, as well as the effect on the outcomes of chemotherapy, so it can be used as an input to overcome malnutrition in ALL children. Method: A retrospective design was performed in Cipto Mangunkusumo Hospital from 2016 until 2018. Total sampling in patients with acute lymphoblastic leukemia who was diagnosed and started chemotherapy at Cipto Mangunkusumo Hospital until the consolidation phase. Result: A total of 141 subjects were included in this study. After consolidation phase, 69.5% of subjects experienced nutritional status improvements, and 30.5% worsened, of which 60% become over nutrition post-consolidation phase. Independent risk factor for the improvement of nutritional status after consolidation phase was the absence of chemotherapy side effects (RR 1.36, 95% CI 1.02 - 1.81). There were no association between type of food and route of feeding with nutritional status improvement of ALL children after consolidation phase. There was association between improvement in nutritional status of ALL children after consolidation phase with the incidence of remission (RR 1.24, 95% CI 1.03 - 1.5). Conclusion: Nutritional status at post-consolidation phase has improved compared to pre- chemotherapy, while those who worsening nutritional status tend to overnutrition. The absence of chemotherapy side effects affects nutritional status improvement of ALL children after consolidation phase. There is a relationship between nutritional status improvement of ALL children after consolidation phase with the incidence of remission.
