    TITLE

    Effect The effectiveness of vitamin D supplementation in preventing

    latent tuberculosis infection among healthy children five years or less

    that are contacts of tuberculosis cases :

    a double blind randomized- control trial

    1. ABSTRACTMany study have reported clearly, that vitamin D activity as immunomodulator

    affect by blood level either genetic polymorphism Vitamin D Receptor (VDR), but the overall

    effect to TB treatment still controversial. There was no report about vitamin D

    supplementation to prevent tuberculosis in healthy child contact TB. This study aim are to

    know about effect of vitamin D supplementation to prevent developing latent tuberculosis in

    children under five years with TB close contact. In this study, we will enrolle the healthy

    children (without infection, without disease) and divided into two groups, group of vitamin D

    supplementation and placebo, twice, day 0 and day 42. We use vitamin D3, with high dosages

    25.000 IU each time. We will evaluate about the vitamin D blood level at baseline and after

    12 weeks. We will check genotype VDR too, to asses the influence on vitamin D respons.

    We use tuberculin skin test to define latent tuberculosis, and the positive results will confirme

    with interferon (IFN) assay. Therefore we analyze the effect with various statistical

    analysis.

    2. EXECUTIVE SUMMARYThere was no doubt that tuberculosis (TB) in children have been transmitted from

    adult TB, especially smear positive and close contact. Risk of infection and disease increase

    by age, therefore can suffered more severe TB disease, furthermore affect quality of life.

    Althought, National Tuberculosis Program (NTP) program gives Isoniazid Prophylaxis

    Therapy (IPT) to every children under five with TB contact, but actually in field generally

    difficult with low compliance, and in fact can drive MDR TB. So we need the other action to

    prevent TB in children TB contact.

    However, the immune system greatly affected the immunopathogenesis to M. tb,

    influenced by various micronutrients, specially concern is vitamin D. Several clinical studies

    found a strong association between vitamin D and TB. The study mainly focused on the

    association of vitamin D deficiency with incidence of TB and improvement of adult TB cases.

    Nursyam in Jakarta, found improvement of sputum conversion of in group addition with

    vitamin D. Recently study carried out by Martineau, patient who were receiving standard TB

    treatment and had been supplemented with vitamin D, found sputum clereance more rapid

    than placebo. However, Wejse et al. found no effect of supplementation on disease outcome.

    In the other hand, some study showed role of genotype Vitamin D Receptor (VDR) on

    macrophage activity.

    There were lack of data about prevention of TB with vitamin D supplementation,

    especially in children. Study to adult TB contact were given a single dose of 100,000 IU (2,5

    mg) vitamin D, demonstrated enhanced immunity to mycobacteria, therefore prevent latent

    TB. However, there are many evidence that vitamin D supplementation have beneficial effect

    on immune system in general, particularly in childhood. Some study demonstrated effect of

    vitamin D supplementation on reduce influenza and pneumonia in children.

    This study aim to find out the effect of vitamin D supplementation to healthy children

    TB contact to prevent latent TB. Our hypothesize is there are different about incidence of laten

    TB between group of vitamin D supplementation and placebo in healthy child TB contact. In

    this study, we will enrolle the healthy children (without infection, without disease) and dividedinto two groups, group of vitamin D supplementation and placebo, twice day 0 and day 42.

    We use vitamin D3, with high dosages 25.000 IU each time. We will evaluate about the

    vitamin D blood level at baseline and after 12 weeks. We will check genotype VDR too, to

    asses the influence on vitamin D respons. Tuberculin skin test was used to define latent

    tuberculosis, and the positive results will confirme with IFN assay. The research assistants,

    research nurses, and participants were unaware of the assignment groups. Therefore we

    analyze the effect with different statistical analyzed according to the data.

    3. INTRODUCTIONTB Global Report 2011 reported 22 high burden countries (HBCs), that contribute to

    80% of TB cases worldwide every year, Indonesia at the fourth rank. More specific, each year

    there were 450.000 new TB cases and 64.000 die.1 Indonesia 2010 data showed there were

    296,272 total TB cases, and 28,312 child TB cases or 9.6%,marked variation betweenprovinces about 1.5% to 17% .2

    It has been clear that tuberculosis (TB) in children have been transmitted from adult

    TB, especially smear positive and close contact. According to Shaw (1954), adult smear-

    positive TB is infectious to 62.5% of the children around him. Even if smear negative but

    culture positive M.tuberculosis 26.8% infected, if smear and culture negative 17.6%.

    Infection and disease increase by age, therefore can become longterm effect according to

    dorman characteristic of M tuberculosis. In case the child has been suffer severe TB disease

    form, furthermore can affected quality of life.3 Althought, NTP program gives Isoniazid

    Prophylaxis Therapy (IPT) to every children under five with TB contact,4 in fact in field

    generally difficult with low compliance,5-7 and actually can drive MDR TB.8 Its important to

    find out the other way to prevent TB in children contact TB.

    The immune system greatly affected human body to againts to M. tuberculosis.

    Celluler immunity have major role (innate and adaptive) and influenced by various

    micronutrients, specially is vitamin D.9Some studies demonstrated that vitamin D regulates

    the expression of specific endogenous antimicrobial peptides on macrophages, stimulate the

    production of cytokine, etc, especially to M. Tuberculosis.10,11 The other studies have reported

    that vitamin D receptor (VDR) genetic polymorphisms also contribute to the work of vitamin

    D as an immune system modulator. 12,13 Both of this condition, can happen event in tropical

    country. In Indonesia, which is actually an equatorial regions with high solar flow, should the

    conversion of vitamin D may occur properly, but there were 3 study showed vitamin D

    deficiency in children.14-16

    Several risk factors were responsible, such as lifestyle changes,many time spent indoor game, as well as malnutrition.17Overall, in worldwide prevalence of

    vitamin D deficiency about 30-50%.18

    Many clinical studies demonstrated association between vitamin D and TB. Most

    of study has been done to adult TB. Nursyam in Jakarta, found improvement of sputum

    conversion of in group addition with vitamin D.19Recently study carried out by Martineau,

    patient who were receiving standard TB treatment and had been supplemented with vitamin

    D, found sputum clereance more rapid than placebo.20 However, Wejse et al found no effect

    of supplementation on disease outcome.21There were limited study in children. One study in

    Bandung found that serum vitamin D level is low in children with tuberculosis .14 The other

    study reported about genotype FokI VDR have role for risk of TB disease, various by race and

    place.22-24

    There were lack of data about prevention of TB with vitamin D supplementation,

    especially in children. Study to adult TB contact were given a single dose of 2,5 mg vitamin

    D, demonstrated enhanced immunity to mycobacteria, therefore prevent latent TB.25 In

    Mongolian school-age children, vitamin D supplementation for 6 month, trend was seen

    toward fewer TST conversions in the vitamin D group.26 However, there are many evidence

    that vitamin D supplementation have beneficial effect on immune system in general,

    particularly in childhood. Some study demonstrated effect of vitamin D supplementation on

    reduce influenza and pneumonia in children.27,28

    According to furthermore needed to find out the other way to prevent latent TB in child

    TB contact, and limited data about vitamin D for prevention TB in this population, we want to

    know about the effect vitamin D supplementation to child TB contact under five years age,

    addition to standart IPT therapy, to prevent latent TB. We design a double blind randomized

    control trial to healthy children TB contact. This is the first clinical trial study in children,

    about this topic, especially in Indonesia.

    Research Questions

    Is Can vitamin D supplementation can reduce incidence ofprevent latent TB infection

    among healthy children aged five years or less that are contacts of in healthy child TB contact

    under five years ageTB cases ?

    Hypothesis

    Child contacts age five years or less that received vitamin D supplementation will be

    less likely to develop latent TB infection compare to those received placebo.

    There are any different about incidence of latent TB between group of vitamin D

    supplementation and placebo in healthy child TB contact under five years age.

    Objectives

    General Main Objectives

    To evaluate the effectiveness overall effect of vitamin D supplementation in healthy

    child TB contacts aged five years or less under 5 years age to reduce the incidencein

    preventingoflatent tuberculosis infection.

    Specific Objective

    Primary objective

    To determine the effect of vitamin D supplementation to tuberculin skin test conversion

    4. SUMMARY OF LITERATURE REVIEW

    Magnitude of problems

    TB Global Report 2011 reported 22 high burden countries (HBCs), that contribute to

    80% of TB cases worldwide every year, Indonesia at the fourth rank. More specific, each year

    there were 450.000 new TB cases and 64.000 died.1 Indonesia 2010 data showed there

    were 296,272 total TB cases, and 28,312 child TB cases or 9.6%,marked variation betweenprovinces about 1.5% to 17%.2 In West Sumatera 2012, there were child TB disease for 3 last

    year, about 4,3-7,4%.29 In 2 years, number of TB cases in Pediatric Department M Djamil

    Hospital are 93, most commonly isolated pulmonary TB.30

    Importance of prevent latent TB in children

    It is clear on TB that M. tuberculosis transmitted from adult TB cases especiallysmear positive, to children around them. Close contact of smear positive sources cause an

    increased risk of TB infection and TB disease in children, especially age under five, either

    developed severe TB cases too. Natural history data show that the vast majority (>95%) of

    children who progress to disease, do so within 6-12 months of primary infection .3 A

    systematic review found prevalence TB infection is high among child contacts, with

    proportion about 24-69%. 31 Other data showed TB infection among them are in West

    Sumatera 69,9% 32and Yogyakarta 35%33

    Early intervention in child TB contact may reduce the burden of cavitating disease and

    associated disease transmission in the community in future adult life. Exposed children

    should be screened and tuberculosis status should be determine. Children aged less than 5

    years who do not have active disease should receive Isoniazid Preventive Therapy (IPT) to

    reduce the likelihood of developing tuberculosis disease. The current recommendation for

    preventive therapy is isoniazid 10 mg/kg daily for 6 months.4Meta-analysis of IPT in HIV-

    uninfected individuals with latent TB infection (LTBI) showed that IPT is effective in

    preventing the development of tuberculosis disease by 60% overall.34 In children, the benefit

  • 7/30/2019 180813 Final-1 Revision Content of Proposal Form 2a 2012-1_rt

    7/34

    7

    is estimated to be greater at around an 80% reduction.34-36

    Despite these benefits, contact investigation and management are rarely carried out in

    resource-poor countries, in which tuberculosis is usually endemic. In fact, there was infrequent

    contact scrining, IPT often not available and poor adherence.7 Two studies from Malawi

    reported an uptake of less than 10%.37 Similarly, a more recent study in India reported that

    among patients with young child contacts, only a quarter had been informed to screen the

    close contacts for tuberculosis and of the availability of IPT to the children. Of 365 children

    under five, only 33 (9%) were actually screened for tuberculosis38. Moreover, newest

    publication showed that by mathematics modelling, community-wide IPT drives drug-resistant

    TB.8

    The poor implementation of contact investigation and management in developing

    countries is likely to relate to the issues regarding health systems/infrastructure and facilities

    as well as human resources capacities, limited resources for Tuberculin Skin Test, low public

    awereness, and it is not easy to convince families of the need for investigation and prolonged

    treatment in well children. So, its important to find out the other way or the addition way to

    prevent TB in children contact TB.

    Vitamin D as an immunomodulator

    The immune system greatly affected the event of latent TB in child TB contact.

    Latent TB will not occur if the natural immunity (innate immunity) works well, play by

    various immune cells including macrophage, dendritic cells, followed by adaptive immunity,

    including IFN, TNF, and other Th2 cytokine. Both the immune system is influenced by

    various micronutrients. One micronutrient that is growing role in natural immunity during the

    last 3 decades, is vitamin D.39

    Vitamin D is a steroid-like protein, that synthesized in the skin during to ultraviolet

    light and is also available in the diet, principally from oily fish. It is readily metabolized in the

    liver to form 25-hydroxy-vitamin D [25(OH)D], the accepted measure of vitamin D status.

    This form is the further metabolized by the 1-hydroxylase enzyme Cyp27B1 in renal to its

    biologically active metabolite, the steroid hormone 1,25-hydroxy-vitamin D.40

    Epidemiologically, approximately 1 million people in the world is estimated to

    have vitamin D insufficiency or deficienc, about 30-50%.

    18

    . Lack of sunlight (during thewinter), vegetarian diet, skin with dark pigmentation, increased pollution, and wear long

    clothes that cover the body, are risk factors that are often found. Habit of living in modern

    times, such as the use of computers, video games, play station, the old television program,

    causing children to spend longer time in the house.40 As a result, exposure to sunlight is

    reduced, the effect on vitamin D levels in the blood. In fact, event in tropical country like

    Indonesia have vitamin D deficiency according the results above. Newest survey by

    SEANUTS 2012, prevalence vitamin D deficiency in Indonesian children about 39%-45,4%,

    various between city and village area.16

    Vitamin D is suspected having effect as potential modulators according to several

    mechanism. There is significant biological plausibility for a clinical association between low

    [25(OH)D] levels and susceptibility to infection, regarding to direct effect of [1,25(OH)2D]

    on innate immunity.11Many immune cells express the VDR, including T and B cells, dendritic

    cells, as well as macrophage. Initial studies found that vitamin D stimulates antimicrobial

    activity, throughout resulting in induction of cathelicidin and/or defensin, both of which are

    potent antimicrobial peptide.41 Autophagy is the other mechanism to kill mycobacteria,

    throught the lysosomal machinery, one of the effect of vitamin D to innate immunity.42,43In

    the state of vitamin D deficiency, infected macrophages can not produce [1,25(OH) 2D] is

    sufficient in the production of cathelicidin settings.41

    Its appear that downstream adaptive immunity can also be modified by [1,25 (OH)2D].

    There were some evidence that vitamin D suppressed IFN production in respons to M.

    tuberculosis antigens.11(Effect vitamin D IFN) Other in vitro study showed that coculture of T

    cells with [1,25 (OH)2D] reduces the number of Th1 cytokine expressing cells (specifically

    IFN and TNF ).41 However, the effect of vitamin D on Th2 cytokine production remain

    unclear.

    In addition, the vitamin D receptor (VDR) polymorphism play a role insusceptibility to TB. The association between TB incidence and other polymorphisms varies

    widely across different ethnic groups. For example, the FokI ff genotype of the VDR appears

    to be most consistently associated with increased susceptibily to TB among Asians, but not

    Africans. A study of patients with TB in Peru, found that genetic polymorphisms vitamin D

    receptor (VDR) is closely related to sputum conversion with auramine staining and culture

    M.tb.44 Fok1 VDR genetic polymorphisms, together with IL-1B and Toll-like receptor 2,

    increasing the incidence of extra pulmonary TB.24Study in children at Bandung, FokI gene

    polymorphism have more risk to TB disease 2,94 times than control group.22

    Evidence based association vitamin D and TB

    The role of vitamin D in TB was first proposed by Peter Davies, and several clinical

    studies found a strong association between vitamin D with TB, likelihood more suffer TB

    disease. Talat study in Pakistan found the role of vitamin D to progression of TB .45Ho-Pham

    in Vietnam report on vitamin D insufficiency is a risk factor for TB incidence in men .46Study

    cross sectional and case control 42 contact TB, found that a sufficient level was a protector

    against TST conversion, and the mean serum level [25(OH)D] in TST conversion cases was

    lower than control.47To know about influence of seasonal variation in vitamin D status and

    TB in Cape Town South Africa, Martineu has done study measure vitamin D level, and found

    reprocical seasonal variation in serum [25(OH)D] concentration and TB incidence.48A meta-

    analysis, concluded that low levels of vitamin D is associated with risk of progression to

    active tuberculosis.49

    Clinical evidence using vitamin D in TB treatment was reported in several studies. An

    RCT study in Guinea-Bissau, did not show any improvement in clinical outcomes of TB

    patients treatment21, but Nursyam in Indonesia, getting the opposite.19 In an Egyptian study

    vitamin D was administred to children with tuberculosis, showing that clinical improvement

    was more evident in patients taking vitamin D as compare to treatment alone.50 The study

    conclude that vitamin D supplementation may be very effective in addition to antituberculosis

    drugs in the treatment of TB children.51 Supplementation with high doses of vitamin D

    accelerated clinical, radiographic improvement in all TB patients and increased host immune

    activation in patient with baseline deficient serum levels. These result suggest a therapeutic

    role for vitamin D in treatment of TB.47

    Vitamin D has been suggested as prophylaxis in TB household contacs, being a low-

    cost intervention that also easy to administer in resource-poor settings .52A single oral dose of

    vitamin D enhanced tuberculosis contacts antimycobacterial immunity in vitro. The finding

    that a single oral dose of 2,5 mg vitamin D corrects profound vitamin D deficiency for at least6 weeks, without causing hypercalcemia, underlines the potential use of this formulation as

    safe, effective, and low cost public health intervention.25. In Mongolian school-age children,

    vitamin D supplementation for 6 month, trend was seen toward fewer TST conversions in the

    vitamin D group.27

    Rationalization to give safety and effective vitamin D supplementation in children

    In connection with the extensive benefits of vitamin D on health, the AAP now

    recommends vitamin D every day at a dose of 400 IU starting from the first few days after

    birth, and passed childhood and adolescence, including the exclusively breastfed babies.

    53

    Vitamin D is well tolerated when administered in accordance with the correct dose. However,

    when given orally in excessive amounts, can increase blood calcium levels, which in the long

    run can be a kidney stone.54

    A meta-analysis indicates that vitamin D3 (cholecalciferol) is more effective in

    raising serum [25(OH)D] concentration than is vitamin D2 (ergocalciferol), so that vitamin D3

    Formatted: Font: 11 pt

    10/34

    10

    is preferred in supplementation.55Some studies used daily dose and the other are single dose.

    In adult, by using 1600 IU daily vitamin D3 compare with 50.000 IU once a month give the

    same effect.56Supplementation vitamin D 800 IU/day in Mongolian school-age children for 6

    month was significant in maintain serum [25(OH)D] consentration.26

    Admistration of cholecalciferol once a day and stop at the week 12 more stabille than

    ergocalsiferol degradation after 6 weeks. A single bolus of 50.000 IU of cholecalsiferol has

    the same peak concentration and not return to baseline at the end of the 28-d after intervention.

    37,55 Side effects are high levels of calcium in the blood (hypercalcaemia), high levels of

    calcium in the urine (hypercalciuria) and allergic (hypersensitivity) reactions. The signs of

    overdose include loss of appetite, feeling sick, being sick, headache, and feeling tired, drowsy

    or weak. Reported toxicity of vitamin D showing hypercalsemia at daily intake of > 1000 mcg

    (40.000 IU)57.

    Knowledge gap

    According to furthermore needed to find out the other way to prevent latent TB in child TB

    contact, and limited data about vitamin D for prevention TB in this population, we want to

    know about the effect vitamin D supplementation to child TB contact under five years age,

    addition to standart IPT therapy, to prevent latent TB, with use 25.000 IU vitamin D3, twice

    in day 0 and day 42.

    Study site

    This study will take place in Padang city, one of the city in West Sumatera province,

    Indonesia. Case notification rate of smear-positive in 20110 in Padang city was 31.4 per 100

    000 population. In 2008, approximately 600 new cases of PTB, both smear-positive and

    smear-negative, were commenced on TB treatment at this site.

    We will recruite the subjectsThe index cases will be identified in several Primary

    Health Cares (PHCs), and Pulmonary clinic at M Djamil hospital, the teaching hospital of

    Faculty of Medicine, Andalas University, Padang. All laboratory studies will be performed in

    Biomedic Laboratory Andalas University.

    Time

    The overall study will be conducted for 12 month with the cohort will be recruited over

    the first 6 month of this study.

    Exclusion criteria:

    o Have been treated or are on TB treatmento Severe wastedo Have severe infections such as measles, typhoid, HIV, etc, in the last 3 months

    Randomization

    We will do simple randomization using a table of random numbers to pick the

    treatment group.

    Sample Size

    The sample size is calculated based on the below formula. The proportion of latent TB

    infection among TB contacts who receive vitamin D supplementation is 11%, whereas

    among those withoutrvitamin D is 27% .

    With assumption that 60% of 600 new PTB cases have at least one child living in the

    same house and 80% of them are eligible for the study, and the different of proportion of

    latent TB are 11% and 27% from previous study26, we calculate sample using formula for

    difference of2 proporsion :

    a. Source case

    Source case is a new case (all ages) of PTB identified during the study period.

    New case is a patient who has sputum smear positif tuberculosis, never had treatmentfor tuberculosis and has taken anti-tuberculosis drugs for less than one month.

    Pulmonary tuberculosis is tuberculosis disease which involves lungs and theparenchyma.

    Positive acid fast bacilli (AFB) is the presence of AFB in microscopy smearaccording to the WHO criteria.

    Sputum Smear Positive tuberculosis will be defined as at least 2 positive initialsputum smears, or 1 positive initial sputum smear with radiographic abnormalities

    consistent with active PTB as determined by the treating doctor, or 1 positive sputum

    smear with a positive sputum culture.

    Sputum Negative Smear PTB will be defined as a patient with pulmonarytuberculosis not meeting the above criteria for smear-positive disease. Diagnostic

    criteria should include: at least two sputum smear examinations negative for AFB; and

    radiographic abnormalities consistent with active pulmonary tuberculosis; and no

    response to a course of broad-spectrum antibiotics (except in a patient for whom there

    is laboratory confirmation or strong clinical evidence of HIV infection); and a

    decision by a clinician to treat with a full course of anti-tuberculosis chemotherapy; or

    positive culture but negative AFB sputum examinations.

    b. For child contacts

    Child TB contact : Certain tuberculosis: the presence of at least one of the following symptoms- cough,

    objective weight loss, unexplained fatigue or lethargy or prolonged fever-, AND at

    least one of bacteriological confirmation, radiology confirmation or certain extra

    pulmonary tuberculosis.

    Probable tuberculosis: any child not meeting strict criteria as defined under certaintuberculosis, in whom the treating clinician started tuberculosis treatment AND a

    clear treatment response was documented. Bacteriology confirmed tuberculosis: the presence of AFB on microscopy and/ or

    M. Tuberculosis on culture.

    Radiology confirmed PTB: the presence of any of childhood intrathoracictuberculosis manifestations in CXR.

    Tuberculosis disease: either certain or probable tuberculosis.

    Latent tuberculosis infection: a positive IGRA and/or reactive TST in the absence ofcertain tuberculosis.

    Tuberculosis exposed or healthy child TB contact, but no latent infection ordisease: negative IGRA and a negative TST in the absence of certain tuberculosis.

    Nutritional status: will be classified using the z-score of WHO growth chart, whichis now the standard used in West Sumatera Indonesia. The classification is based on

    the weight for height as follows:

    Severe wasted: < - 3 SD Wasted: -2 to -2 SD Well-nourished: -2 to + 2 SD Overweight: +2 to + 3 SD

    Obese: > + 3 SD

    c. Tuberculosis related symptoms

    Cough: any cough regardless the duration, remitting or not remitting Fever: body temperature of > 38 C Weight loss: weight loss or not gaining weight in the preceding 3 months or the loss

    of more than 10% of bodyweight (minimum 1 kg) over any time interval) despite at

    least 2 weeks of confirmed adequate nutrition

    Fatigue: unexplained perceived decrease in playfulness/activity since the onset ofcoughing, reported by parents/caregiver

    Chest pain: chest pain reported by the child. Hemoptysis: blood in the sputum (not hematemesis or a nose bleed) Night sweat: regular sweating that requires a dry set of nightclothes.

    children aged < 5 years or less living in the household, the source case will be informed

    about this study by the attending clinician. Informed consent then will be asked from the

    parent/guardian who agrees to involve to the study and whose children are eligible for the

    study.

    Baseline assessment

    Home visit

    After eligibility assessment and informed consent, study nurse/doctor will visit the

    subject at home to identify the location of subjects house for follow up purpose and

    to complete baseline data as follows:

    Demographic and clinical data using a questionnaireSubjects characteristics, source case characteristics and other data

    Physical examination Weight and height as well as general examination (detail in the

    questionnaire)

    Tuberculin skin test (TST)Intradermal injection of 0.1 ml of 2 TU of tuberculine purified protein

    derivate (PPD) RT 23 in the volar by trained research nurses.

    The result of TST of transversal diameter of induration will be measured at72 hours by study doctor/nurse at Sardjito hospital during hospital visit for

    further invesigation. If the subject does not come to the hospital at the

    scheduled time, home visit will be done to read the TST result,

    The result will be considered positive if the induration is > 10 mm regardlessthe BCG vaccination, or > 5 mm in severe malnourished or

    immunocompromised subjects.

    Blood collectionWe will performs aseptically form of peripheral blood aspiration. Peripheral

    venous blood sampling as much as 5 ml aseptic have done by study nurse. We

    will examine blood samples within 1 x 24 hours for levels of vitamin D.

    IGRA examination

    We will determine the TB status by examination of the peripheral blood IGRA. If

    increasing levels of IFN, confirmation checks will be performed 1 week later.

    Increasing IFN in two measurements are considered positive. IGRA positive value

    means that the sample is clinically latent tuberculosis (TB infection). Samples are

    included in this phase of research is showing negative IGRA results (not infected with

    TB). IGRA is an analytical examination of IFN levels in cultured lymphocytes

    induced with the ESAT-6. We will isolate the lymphocytes from blood with the

    Hypaque Ficol then culture with the concentration of 1 x 10 6 cells / well and induced

    with the ESAT-6 M. tuberculosis at a concentration of 0.5 ug / ml. On the 6th day of

    culture, the supernatant is taken and examined levels of IFN with the IFN ELISA kit

    (Abcam). The result is read with the ELISA READER. IFN concentrations are based

    on the normal curve composed from normal values. For comparison,

    phytohemaglutinin is used for positive control and aquadest as a negative control.

    Clinical and Radiological Examination

    All children is going through a routine clinical examination and radiological

    examination if IGRA is increasing in the two measurements. If proven TB disease,

    OAT treatment will be given. This child is not included in the study group.

    DNA extraction

    We will extract DNA from 0.2 ml of cell suspension morphonuclear using DNA

    extraction kit (Qiagen, Chatsworth, USA). Protocol correspond with the procedures

    developed by the manufacturer.

    DNA amplification

    Models and primers used for amplification are performed according to the protocolperformed by Liu et al (2006) with some modifications to the optimization.

    Primers used were:

    BsmI. The result then electrophoreses on 2% agarose gel and visualized with

    Cybergreen. Observations are made with a gel dock.

    Allocation of vitamin D supplementation

    All of the healthy children with close contact, divide into two group. First group is

    supplementation of vitamin D which given orally at day 1 and day 42 and the second

    group is given the placebo. Mixture of vitamin D will be prepared by the pharmacy staff

    that have been selected. Vitamin D and placebo preparations known only by the two

    researchers. The main research subjects and investigators and laboratory staff, do not know

    what kind of preparations are given.

    After 12 weeks of supplementation, we do TST and collect the blood sample to measure

    the IFN level and vitamin D level. Higher IFN level and conversion of TST means the

    children developed latent tuberculosis. After that we analyze is there any correlation

    between vitamin D supplementation and latent tuberculosis. We also analyzed

    polymorphism role in tuberculosis infection.

    Statistics analysis

    Data will be recorded on a data collection form at baseline and follow-up visits. Datawill be entered to the database which was developed using SPSS.

    The data will be summarized as a proportion or a mean or median, where appropriate.

    Comparison of proportions of outcomes between groups were tested using chi square(X2) test; whereas comparisons of mean or median used student t-test for normallydistributed data, and Mann-Whitney rank sum test for non parametric data. A p valueof < 0.05 was considered as statistically significant. Confidence intervals (CI) werecalculated for the prevalence of an outcome. The effectiveness of vitamin D in preventingLTBI will be presented as an Odd Ratio with 95% confidence interval (CI).

    Descriptive statistics Frequencies (gender, contact TB history, level positive smear of index case, VDR

    genetic polymorphism ), percent distributions.

    Mean/Median and standard deviation/IQR for normally or no-normally distributeddata (age, socioeconomic, nutritional status, vitamin D level).

    Analytic statistics Prevalence of vitamin D deficiency and VDR genetic polymorphysm with 95% CI. Chi-square test for comparisons of categorical variables. T-test for comparisons of continuous variables (age). Odds ratio and confidence interval will be calculated for studying the association

    and incindence of latent TB.

    Employ a two-tailed alpha () of 0.05 to determine significance.

    Ethical Clearance

    The ethical clearance will be based on the man using protocol as the research subject and

    approved will be submitted to the by Ethical Commitee of Faculty of Medicine Andalas

    University.

    Informed Consent

    All the subject are being informed about the research procedure, especially to the parent as the

    person responsible, if they were understood and has given time to ask question, they will sign

    the informed consent letter.

    Quality Control

    Selection Bias In order to ensure that the sample is representative, random sampling

    approach will be used to select the community clinics for the study.

    Information Bias We will use the structure questionnaire for collect the data about contact

    history, TB symptom, etc.

    Re-training laboratory technical. Pilot study: To prevent laboratory results bias, we will a pilot study to 15-20

    blood sample, for examine vitamin D level, IGRA, VDR genetic

    polymorphism, etc.

    Strengths and Limitations

    Strengths

    1. The first study on vitamin D supplementation effect in child contact TB2. Quiet large simple size;3. Team members with expertise in Pediatrics TB, Clinical Nutrition, Biomolecular

    Microbiology;

    4. Use of validated effect of vitamin D supplementation in vivo

    Limitations

    1. We do not use normal control (no contact TB) to compare vitamin Dsupplementation effect.

    2. We should still determine the age group < 5 years, according to the focus on thisage group to prevent latent TB in WHO policy, due to lack of immunity capability

    to againt M. tuberculosis.

    8. APPENDICES

    CONSENT TO PARTICIPATE IN RESEARCH

    Effect of vitamin D supplementation to develope latent tuberculosis in healthychildren under five years age with tuberculosis contact :

    a double blind randomized- control trial

    Parental Consent form

    We invite your child to participate in a research study conducted at the study site by Principal

    investigators name (s). Your childs participation in this study is voluntary. You should read

    the information below, and ask questions about anything you do not understand, before

    deciding whether or not to allow your child to participate.

    PURPOSE OF THE STUDY

    This study is to examinine the child uder 5 years old which close contact to tuberculosis

    adult patient at home. This child is highly possibility to get tuberculosis. By doing this

    research, we will know the infection status and the treatment will be given if your child

    infected. If your child didnt get tuberculosis infection, we will examine the blood to know

    the level of vitamin D and genetic receptor of vitamin D. From many studies vitamin D,

    could prevent the TB infection. We will give supplementation of vitamin D to your child

    for 3 month and we will check the blood again and examine the infection status. The

    supplementation and examination are free of charge.

    DURATION AND LOCATION

    The child will be supplemented vitamin D for 3 month, so your childs participation in this

    study will last for approximately 3-4 months. This study will be conducted at Biomedical

    laboratory.

    PROCEDURES

    If you allow your child to volunteer to participate in this study, we would ask your child to

    do the following things:

    1. Get peripheral blood sample for interferon gamma examination, vitamin D level andpolymorphism, clinical evaluation, and chest X-rays.

    2. Supplementation of vitamin D and placebo for 3 month3. Get peripheral blood sample interferon gamma examination and vitamin D level,

    clinical evaluation after 3 months.

    POTENTIAL RISKS AND DISCOMFORTS

    1.No study is without some risk. Some procedure will discomforts the child, such asperipheral blood sampling and chest X-rays. It has some risk such as fail to get the

    blood in one times punction. We will minimize this risk by doing the punction with

    professional operator.

    2. Having vitamin D supplementation will discomfort your child because she/he mustdrink the vitamin D daily for 3 months. So far, no risk of drink vitamin D but "there

    may also be risks and discomforts which are not yet known".

    ANTICIPATED BENEFITS TO SUBJECTS

    The benefit of this research is to know the infection tuberculosiss status of your childand she/he will get the treatment if positive infected and get sick. If your child is

    healthy, by giving vitamin D we will prove the protection effect of vitamin D to your

    child. If it is proven, may be our government will implement a policy about vitamin D

    supplementation to high risk children whom has close contact to tuberculosis adult

    suffer.

    PAYMENT FOR PARTICIPATION

    All examination and the vitamin that will be given are free of charge.

    CONFIDENTIALITY

    When the results of the research are published or discussed in conferences, no

    information will be included that would reveal your childs identity. If photographs,

    videos, or audio-tape recordings of you will be used for educational purposes, your
