Oral manifestations resulting from chemotherapy in children with acute lymphoblastic leukemia

Assessment of the Changes in the Salivary Profile and Its Clinical Correlation in Children with Acute Lymphoblastic Leukemia Undergoing Chemotherapy: A Follow-up Study

Aim

To assess the changes in salivary profile and its clinical correlation in patients with acute lymphoblastic leukemia (ALL) undergoing chemotherapy.

Materials and methods

Children who have been diagnosed with ALL undergoing chemotherapy at Bharati Hospital, Pune, were included in the study. Those children were included who fulfilled the following inclusion and exclusion criteria. Stimulated salivary samples were collected in sterile vials at 1-, 3-, and 6-month intervals and ware assessed for salivary pH and buffering capacity. Caries and oral manifestations were also checked at each interval.

Results

A total of 25 children with ALL undergoing chemotherapy were included to participate in the study. The results were analyzed using Statistical Package for the Social Sciences software. There was a statistically significant difference in the change in salivary pH during the 1st and 6th months of chemotherapy (p-value of 0.001). Salivary buffering capacity was also found to be low in these patients during the 1st month of chemotherapy, which gradually increased during the entire course of chemotherapy (p-value of 0.011). Progression of dental caries was seen during the entire course of treatment.

Conclusion

All the major changes were seen in the 1st month, that is, the induction phase of chemotherapy. Hence, we can say this is the most affected phase of chemotherapy.

Clinical significance

The parents and children should be educated and motivated to maintain proper oral hygiene. Whenever possible, all preventive dental procedures should be undertaken before the start of chemotherapy to avoid future complications.

Antineoplastic therapy in childhood cancer patients presents a negative impact in the periodontal tissues: a cohort study

OBJECTIVES

To investigate the effect of antineoplastic therapy (AT) in the periodontal tissues of childhood cancer (CC) patients.

MATERIALS AND METHODS

Seventy-two individuals were divided into CC (n=36) and healthy individuals (control group-CG, n=36). Demographics, hygiene habits, CC type, and AT were collected. Salivary flow and the presence and concentration of Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Tannerella forsythia, and Fusobacterium nucleatum were analyzed. Clinical evaluation included plaque (PI) and gingival indexes (GI), periodontal probing depth (PPD), and clinical attachment level (CAL). Patients were classified into periodontal health, gingivitis, or periodontitis. Descriptive statistics, T test, Mann-Whitney test, chi-square, Fisher's exact test, and two-way analysis of variance were used (p<0.05).

RESULTS

The mean age of the patients was similar (CC 12.0±3.9 years and CG 12.0±4.0 years). In the CC group, all patients underwent chemotherapy and nine radiotherapy. Color/race, income, and family education showed significant differences between groups. There was no difference between groups in salivary flow. Higher levels of Fusobacterium nucleatum were seen in CC (p=0.02). Significant difference between groups was found for PI (CC: 30.5%, CG: 22.6%), GI (CC: 28.8%, CG: 17.3%), PPD (CC: 1.77 mm, CG: 1.61 mm), and CAL (CC: 1.77 mm, CG: 1.57 mm), periodontal health (CC: 3, CG: 7), gingivitis (CC: 16, CG: 24), or periodontitis (CC: 17, CG: 5).

CONCLUSION

AT in CC patients presents a negative impact in the periodontal and microbiological parameters.

CLINICAL RELEVANCE

Childhood cancer individuals showed worse periodontal parameters and higher levels of Fusobacterium nucleatum in the saliva when compared to healthy individuals.

Exploring the Impact of Blood Disorders on Dental Caries

Blood comprises various cellular elements and serves as our immune system's second line of defense. Deviations from its normal composition can have adverse effects on health. At the same time, the oral mucosa in the oral cavity functions as the body's first line of defense, and any anomalies or diseases within it can give rise to both systemic and oral complications. If left untreated, caries can lead to severe tooth damage or extraction, potentially affecting an individual's nutrition and overall health. This review article focuses on the importance of understanding the intricate relationship between blood disorders and oral health. It underscores the profound impact of oral manifestations of blood disorders such as β-thalassemia, sickle cell disease, iron deficiency anemia, leukemia, hemophilia, Plummer-Vinson syndrome, erythroblastosis fetalis, Fanconi anemia, cyclic neutropenia, and acute lymphoblastic leukemia on the overall well-being of an individual.

Chemotherapy-associated oral complications in a south Indian population: a cross-sectional study

Over the years, chemotherapy (CT) has evolved as an essential therapeutic modality for cancer, with oral manifestations frequently encountered as complications of cancer CT. Our study aimed to assess the prevalence of oral complications during CT and evaluate the significance of independent risk factors (age, gender, socio-economic status, oral hygiene practices etc). A cross-sectional study was carried out in a tertiary cancer hospital in Bhubaneswar, Odisha, India, in which a total of 138 hospitalized patients undergoing CT and fulfilling the inclusion and exclusion criteria were included. Comprehensive history and rigorous clinical examination eliciting the oral manifestations were carried out. Around 60% of patients exhibited oral manifestations. Xerostomia and lichenoid reactions were the highest and lowest recorded manifestations. Higher frequencies of oral lesions occurred in patients with breast cancer, TNM stage III, and with the administration of the docetaxel. Also, patients in the older age group, poor socio-economic status, poor quality of life, poor oral hygiene practices, and longer CT duration demonstrated more oral lesions. Individuals subjected to a dental evaluation either before or during CT exhibited a reduction in the number of oral features. Several oral complications were reported in the present study. All patients undergoing chemotherapy must receive reinforcement of oral hygiene instructions and dental evaluation before, during, and after chemotherapy treatment. The study also emphasizes the importance of oral health physician inclusion in the multidisciplinary cancer treatment team.

Oral Health, Caries Risk Profiles, and Oral Microbiome of Pediatric Patients with Leukemia Submitted to Chemotherapy

Background

Chemotherapy is the primary treatment modality used for patients with acute lymphoblastic leukemia (ALL), but inevitably causes microbiota-related oral complications. This study is aimed at investigating the effects of chemotherapy on oral health status, caries risk, and oral microbiome in pediatric patients with ALL.

Methods

Thirty-nine children with ALL receiving chemotherapy were enrolled, and a gender-, age-, dentition stage, and socioeconomic class matched healthy counterpart were recruited. Demographic information and overall health condition were obtained through the questionnaire and medical records. Oral examination was performed to assess caries and salivary status, plaque index, and other oral manifestations. Cariogram was used to assess the overall caries risk. Supragingival samples of thirteen ALL subjects and their counterparts were randomly selected to perform a 16S ribosomal RNA gene 454 pyrosequencing. Raw sequence data were screened, trimmed, and filtered using Seqcln and MOTHUR.

Results

The prevalence of dental caries, gingivitis, oral mucositis, xerostomia, and candidiasis in ALL groups was higher than that of the control group (p < 0.05). Children with ALL demonstrated higher caries risk compared to healthy controls (HC) based upon Cariogram (p < 0.05). The oral microbial structure of ALL patients receiving chemotherapy is different from that of healthy controls. Oral microbiota of ALL groups showed less alpha diversity and significant differences in the composition of the oral microbiome compared to healthy controls.

Conclusions

ALL patients receiving chemotherapy demonstrated compromised oral health, high caries risk, alteration of caries-related factors, and dysbiosis of oral microbiota. These findings may be of clinical importance in developing better strategies for personalized preventive management of oral diseases for pediatric children with ALL.

Evaluating the additive effect of Persica and chlorhexidine mouthwashes on oral health status of children receiving chemotherapy for their hematomalignancy: A randomized clinical trial

Background

No definitive protocol has been introduced for treatment or prevention of chemotherapy induced mucositis. The aim of this study was to assess the additive effect of Persica and chlorhexidine on chemotherapy induced mucositis of children with hematomalignancies.

Material and Methods

This randomized clinical trial was performed on 44 children aged 6 to 12 years who were under a similar maintenance chemotherapy protocol for their hematomalignancies. The clinician instructed oral hygiene cares to the patients and their parents and the severity of the mucositis and oral health status of patients were evaluated according to Oral Assessment Guide index. Then, the patients were randomly assigned to one of two experimental groups and were instructed to rinse either with Persica oral drops or normal saline, twice a day for two weeks. Subsequently, the patients in both groups were educated to rinse with chlorhexidine for 30 seconds and avoid eating for an hour. Second and third oral examinations were performed on the 8th and 15th day using the same questionnaire.

Results

Comparing severity of mucositis and oral health status of patients did not show any significant difference between treatment groups in either of examination sessions (p>0.05). However, both treatment groups showed statistically significant oral health improvement, in terms of mucositis, plaque accumulation and gingival condition, in 14 days following mouthrinses administration (p<0.05).

Conclusions

Both mouth-rinse combinations were effective on mucositis, plaque and gingival status of children receiving chemotherapy. However, Persica does not seem to pose additional effect on chlorhexidine in decreasing severity of chemotherapy induced mucositis.

Key words:Mucositis, chemotherapy, children, chlorhexidine, Persica.

Oral health status and its determinants in children with leukaemia at the Radiation and Isotope Center Khartoum, Khartoum State, Sudan

The burden of oral health diseases in children with leukaemia and the impact of cancer treatment on their oral health have not been studied in Sudan. The present study assesses the oral health status of leukemic children through measuring caries experience, gingival status, oral hygiene status and mucositis. It also explores the association between the oral health status of children with leukaemia and their parental education, oral hygiene habits, treatment stage and type of leukaemia. A cross sectional hospital-based study was conducted at the Radiation and Isotope Center Khartoum, Khartoum State. A total of 87 children were included in this study. Data were collected by interviewer questionnaire and clinical examination. The oral health status revealed high prevalence of untreated dental caries (37.9%) and the majority (67.9%) of children had poor oral hygiene. Nearly, all children with leukaemia (93.1%) had never visited a dental health facility in their lives. Regarding the treatment stages of leukaemia, the severity of dental caries was found to be more significant in the maintenance phase, while oral mucositis was more significant in the induction phase.

Differences between the oral changes presented by patients with solid and hematologic tumors during the chemotherapeutic treatment

Objective:

This study sought to identify the differences between the oral changes presented by patients with solid and hematologic tumors during chemotherapeutic treatment.

Methodology:

This is an observational, prospective and quantitative study using direct documentation by follow-up of 105 patients from 0 to 18 years using the modified Oral Assessment Guide (OAG). Of the 105 patients analyzed, 57 (54.3%) were boys with 7.3 years (±5.2) mean age. Hematologic neoplasms accounted for 51.4% of all cases.

Results:

Voice, lips, tongue, and saliva changes were not significantly different (p>0.05) between patients with solid or hematologic tumors and during the follow-up. From the 6^th until the 10^th week of chemotherapeutic treatment alterations in swallowing function, in the mucous membrane (buccal mucosa and palate), in the labial mucosa, and in the gingiva occurred and were distributed differently between the two tumors groups (p<0.05). The main alterations were observed in patients with hematologic tumors.

Conclusion:

It was concluded that the oral changes during the chemotherapeutic treatment occurred especially in swallowing function, in the mucous membrane, in the labial mucosa and in the gingiva, and these alterations were found mainly in patients with hematologic tumors.

Nigella sativa Oil Mouth Rinse Improves Chemotherapy-Induced Oral Mucositis in Patients with Acute Myeloid Leukemia

Objective

The present study aims at evaluating the beneficial effect of Nigella sativa (NS) oil mouth rinse in the management of chemotherapy- (CT-) induced oral mucositis (OM) in patients with acute myeloid leukemia (AML).

Methods

Fifty-four AML patients were participated in this study and randomly allocated to either the test group or a control group. The patients of the test group received NS oil mouth rinse during 28-day CT, while the participants of the control group received a "magic mouthwash" formula. The primary outcome of this study was the incidence and severity of CT-induced OM in terms of erythema and ulcer. The secondary outcomes were the pain severity score, swallowing function, and the salivary concentrations of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α).

Results

NS oil mouth rinse attenuated the progression of CT-induced OM compared with the control formula (AUC = 5.9 vs. 38.4, P < 0.05) and significantly decreased the erythema and ulceration scores (AUC of total OMAS = 11.4 vs. 85.9, P < 0.001) compared with the magic mouthwash formula. It also reduced the pain score and enabled all the participants of this group to consume normal food during treatment. It significantly decreased salivary IL-6 (AUC = 7376 vs. 16599, P < 0.001), while the changes of TNF-α levels were not significant (AUC = 676.9 vs. 885.2, P > 0.05).

Conclusions

NS oil mouth rinse is effective in attenuating the severity of CT-induced OM and improves the pain and swallowing function in AML patients.

Oral health status before, during and after antineoplastic treatment at a cancer institute in Barranquilla, Colombia

Chemotherapy and radiotherapy are aggressive treatments for cancer management. Both therapies make the stomatogatic system vulnerable to adverse effects on the oral mucosa and hard tissues. This may result in severe oral complications that can affect the quality of life of the oncologic patient. Consequently, oral diagnosis and interdisciplinary management by the stomatologist are critical for cancer treatment, regardless of its location. Objective. To determine the oral health status of cancer patients before, during and after antineoplastic treatment at a cancer institute in the city of Barranquilla, Colombia. Materials and Methods. A descriptive, longitudinal and prospective study of 131 cancer patients, was conducted. The study consisted of initial stomatological assessment of the antineoplastic therapy; classification according to the antineoplastic therapy given by the oncologist; a second stomatological assessment during treatment; and a final stomatological assessment or evaluation forty days after the end of therapy. Descriptive statistics, chi-square and MacNemar test were used to compare and identify variances at the different stages. Results. Female patients accounted for 69%, and breast cancer had 24% prevalence among the included subjects. At the initial stomatological assessment, high frequency lesions were identified, such as generalized biofilm-associated gingivitis in 69% of the cases, followed by oral candidiasis in 61%. The specific prevalence of lesions was 10.65%. In the second stomatological assessment, a greater frequency of periodontal abscesses was observed in 31%, and oral mucositis type II in 18%. The third clinical assessment showed significant changes in oral health status; an increase in the frequency of gingivitis was found in 9.9% (p<0.001); unlike before and during, there was an increment in dental caries of 26.73% (p<0.00000) at this last stage, root remains increased by 39.53% (p<0.00000), and finally, xerostomia increased by 45%. Oral candidiasis was the only lesion that showed improvement. Conclusion. An increase in the number of lesions was observed during and after antineoplastic treatment. The oral cavity is susceptible to antineoplastic treatments; gingivitis, candidiasis, xerostomia, and mucositis were observed, among others conditions.

Identification of New Inhibitors with Potential Antitumor Activity from Polypeptide Structures via Hierarchical Virtual Screening

Leukemias are neoplasms that affect hematopoietic cells, which are developed by genetic alterations (mutations) that lead to the loss of proliferation control mechanisms (maturation and/or cell death). The α4β1 integrin receptor is a therapeutic target for inflammation, autoimmune diseases and lymphoid tumors. This study was carried out to search through the antagonists-based virtual screening for α4β1 receptor. Initially, seventeen (17) structures were selected (based on the inhibitory activity values, IC₅₀) and the structure with the best value was chosen as the pivot. The pharmacophoric pattern was determined from the online PharmaGist server and resulted in a model of score value equal to 97.940 with 15 pharmacophoric characteristics that were statistically evaluated via Pearson correlations, principal component analysis (PCA) and hierarchical clustering analysis (HCA). A refined model generated four pharmacophoric hypotheses totaling 1.478 structures set of Zinc_database. After, the pharmacokinetic, toxicological and biological activity predictions were realized comparing with pivot structure that resulted in five (ZINC72088291, ZINC68842860, ZINC14365931, ZINC09588345 and ZINC91247798) structures with optimal in silico predictions. Therefore, future studies are needed to confirm antitumor potential activity of molecules selected this work with in vitro and in vivo assays.

Oral health in children with acute lymphoblastic leukaemia: before and after chemotherapy treatment

AIM

To evaluate changes in the oral health status of children under the age of 14 years with acute lymphoblastic leukaemia (ALL) attending a cancer centre before and after chemotherapy treatment.

MATERIALS AND METHODS

A total of 32 children with ALL without distinction of gender were selected for study. The oral cavity of the patients was evaluated before the induction stage and 17 days later. Clinical evaluation of the submandibular, submental, and cervical lymph nodes was performed. Saliva samples were collected during the early morning hours. Bacterial plaque was assessed by using the Silness and Löe plaque index (SLPI) and gingiva status was evaluated with the gingival Löe and Silness index (GLSI). The WHO toxicity oral scale was used to record the degree of oral mucositis. The resulting data were analysed with McNemar's test, t test (for related samples), and Wilcoxon test.

RESULTS

There were statistically significant differences for palpable lymph nodes, paleness of oral mucosa, and ecchymoseis, respectively, P ≤ 0.000, P = 0.03, and P = 0.01, with these manifestations decreasing significantly after treatment. Incipient gingivitis had frequencies of 71.9% and 75% before and after treatment, respectively. The mean SLPI score declined significantly from 1.16 ± 0.52 (before treatment) to 0.56 ± 0.36 (after treatment) (P < 0.000); salivary flow increased significantly from 0.54 ± 0.34 to 1.22 ± 1.07 after chemotherapy treatment (P < 0.00). Oral mucositis was present in 24 children (75%) with a 1-2 severity level.

CONCLUSIONS

After chemotherapy treatment, there were changes in the oral conditions of children with ALL. Some manifestations decreased after treatment, whereas in others increased.

Factors Contributing to the Duration of Chemotherapy-Induced Severe Oral Mucositis in Oncopediatric Patients

This study analyzes the factors contributing to the duration of severe oral mucositis in oncopediatric patients. A longitudinal study was conducted in the pediatric department of a cancer referral hospital between 2013 and 2017. Seventy-three patients diagnosed with cancer undergoing chemotherapy protocols were analyzed. Oral evaluations were performed using the Modified Oral Assessment Guide criteria, and the data were collected from the patients’ records. The Kaplan-Meier method was used to estimate survival curves. Most patients were males (52.1%), of mixed race (“pardo”) (49.3%), with a mean age of 7.56 years (±5.34). There was a predominance of patients diagnosed with solid tumors (52.1%), with no metastasis (86.3%), using natural product chemotherapeutics (56.2%), who had not undergone a bone marrow transplant (97.3%); amputation was observed in 35.6% of patients, while death rates were as high as 8.2%. The survival analysis estimated a mean time of 30.6 days until complete remission of severe oral mucositis. The regression analysis showed that patients over 10 years old had a median mucositis duration 1.4 times greater than those at the age of 10 years or younger. Patients without metastasis had a median mucositis duration 1.7 times greater than those with metastasis (p-value ≤ 0.10). Increasing age and the absence of metastasis were conditions that prolonged the duration of severe oral mucositis.

DENTAL CONSIDERATIONS FOR LEUKEMIC PEDIATRIC PATIENTS: AN UPDATED REVIEW FOR GENERAL DENTAL PRACTITIONER

The early signs of leukemia can usually manifest in the oral cavity due to infiltration of leukemic cells or due to associated decline in normal marrow elements, especially in the acute phase of leukemia, as common lesions at this stage of the disease can be screened and diagnosed by the dentist. Therefore, the dental community should be aware of the oral manifestations of leukemia and oral complications of anticancer treatment. This can eliminate the oral symptoms of the disease and to improve quality of life for these patients. An extensive search in PubMed line using a combination of terms like “leukemia, children, dental, Acute lymphoblastic leukemia, pediatric” for last ten years was made. Reviews and case reports concerned about acute lymphoblastic leukemia in children were all collected and analyzed and data were extracted. Accordingly, the aim of this review is to highlight on the oral presentations of leukemia in children attending dental clinics and the management of its undesirable side effects.
