About this study

Official title: Clinical-microbiological Study of Oral Health Condition and Quality of Life of Children/Adolescent With Acute Lymphoid Leukemia and Acute Myeloid

Among the different types of cancer that most affect children, leukemia is the principal. One of the main treatments for leukemia is chemotherapy. Among the most common side effects of chemotherapy are nausea and/or vomiting, diarrhea, fatigue, alopecia, neuropathy, opportunistic infections, and oral mucositis. It is still necessary to establish which microorganisms are predominant in the oral microbiota of children with leukemia, which factors influence it, what is its relationship with oral mucositis and what is their impact in the quality of life. To better understand the risks of secondary infection, it is important to develop preventive and/or therapeutic strategies to control the side effects of antineoplastic treatment in the mouth that may negatively impact the quality of life, to expose the risk of death as well as raise hospital costs for the care of children with leukemia. Objective: To identify the clinical characteristics of the oral condition, types of microorganisms of the oral microbiota, and quality of life in children/adolescents with acute lymphoid leukemia and acute myeloid leukemia before and during antineoplastic treatment, and compare them with healthy children/adolescent individuals. Methodology: Longitudinal, case-control study, with a convenience sample. The study group, composed of children/adolescent individuals who have a definitive diagnosis of acute lymphoid leukemia or acute myeloid leukemia. The control group, non-syndromic children/adolescents, with no history of cancer, matched by age and gender. The clinical condition of the mouth will be evaluated by means of indexes: dental caries index (dmft index), gingival index (GA), and simplified oral hygiene index. The assessment of the quality of life through the ohip-14 and POS-version14 quality of life questionnaire and microbiological evaluation of saliva through MALDI-TOF analysis. Statistical analysis will be performed through relative risk for cohort study with more than three paired groups. Odds ratio, for the control group more than three controlled groups and Mcnemere, for comparison with the control group, for more than three paired groups.

Read the detailed description

In children, non-communicable diseases such as cancer are increasing every year. It became a priority on the global child health agenda. Each year, there were an estimated 30.000 new cases of cancer in children/adolescent individuals. In Brazil, between 2018-2019, there were 12.500 new cases of cancer in children and adolescents up to 19 years of age. The mortality rate was 7.917 cases.

Among the types of cancer that most affect children, leukemia is the most prevalent. In 2018, there was a forecast of 437.033 new cases of leukemia with a mortality of 309.006 individuals around the world.

One of the main treatments for leukemia is chemotherapy, the side effects can affect different parts of the body that may present since the beginning of the treatment. Chemotherapy produces systemic toxicity resulting in anemia, leukopenia, and thrombocytopenia that is more intense in the treatment of oncohematological diseases when compared to solid tumors. Among the most common side effects of chemotherapy are included nausea and/or vomiting, diarrhea, fatigue, alopecia, neuropathy, opportunistic infections, and oral mucositis.

Some studies reported that the intensity of oral mucositis, as well as the risk of sepsis from secondary infection in the mouth of individuals with cancer, they can be influenced by some specific microorganisms present in the oral cavity. Factors such as oral hygiene, presence of dental caries, and periodontal disease may be related to the type of microorganisms present in the oral cavity. There is a lack of studies about microbiota oral in leukemic children. Oral microbiota in children with leukemia is predominantly composed of gram-positive microorganisms such as Streptococus viridans, Streptococous mutans and Lactobacillus when compared to adults oral microbiota where gram-negatives microorganisms such as Klebsiella spp., E coli, Enterobacter, Pseudomonas spp. predominate. It is noteworthy that it is necessary to establish what kind of microorganisms are predominant in the oral microbiota of children with leukemia, also which factors influence it, and what is the relationship among the oral mucositis, general clinical status, and quality of life of the children/adolescent with cancer.

Therefore, it is important to identify the risks of secondary infection in oral cavity, to be able to develop preventive and/or therapeutic strategies to control the side effects of antineoplastic treatment in the mouth that can negatively impact the quality of life, expose the risk of death as well as raise hospital costs for the care of children with leukemia.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Evaluation of dental condition

    Dental condition is going to be evaluated by dental caries index (dmft index) (WHO, 2013).

    Measured: 5 minutes to 10 minutes

  2. Evalulation of periodontal condition

    The periodontal evaluation it is goning to be evaluated by and gingival index (LOE, 1964)

    Measured: 10 minutes to 15 minutes

  3. Evalulation of oral hygiene

    Oral hygiene is going to be evaluated by simplified oral hygiene index (IHO-S).

    Measured: 10 minutes to 15 minutes

  4. To evaluate oral mucositis

    the presence of oral mucositis will be evaluated through the graduation recommended by the World Health Organization (WHO) (WHO, 1979).

    Measured: 5 minutes to 10 minutes

  5. Evaluation of oral pain of oral mucositis

    The oral pain because of the oral mucositis is going to be evaluated by Visual Analogue Scael of pain and it is gonig to be scaled by the Wong-Backer face scale which is from 0 to 10 pontuation, being 1 the minimium pain percivied and 10 de maximium pain percieved. This evaluation it is going to be make only in children with leukemia.

    Measured: 1 minutes to 2 minutes

  6. Saliva collection

    The collection of the saliva is going to be made by an unstimulated technic. The minimum of 2 mL to maximum of 10 ml of saliva are going to be collected.

    Measured: 15 minutes to 20 minutes

  7. to evaluate the quality of life of children percieved by parents

    A Pediatric Quality of Life Inventory Version 4.0 questionaire is going to be answered by children parentes with the following five options: never = 0, almost never = 1, sometimes = 2, often = 3, and almost always = 4.

    Measured: 10 to 15 minutes

  8. to evaluate the impact of oral condition on the quality of life percieved by the children

    A OHIP-14 (Oral Health Impact Profile) questionnaire (adapted for children) is going to be applied to children with 6 years old or children older than 6 years old. The questionaire is going to be answered with five options: never = 0, almost never =1 , sometimes = 2, often = 3, and almost always = 4 which is represented by a face scale.

    Measured: 10 to 15 minutes
