Abstract:
Inflammatory diseases of the oral mucosa are common in
patients with chronic kidney disease (CKD), often exacerbated by systemic
oxidative stress and impaired immune regulation. This study evaluates the
effectiveness of a combined therapeutic approach incorporating antiseptic
therapy and antioxidant modulation through laser blood irradiation. One
hundred CKD patients with oral mucosal inflammation were divided into two
groups: the control group received standard symptomatic and antiseptic
treatment, while the main group received additional low-level laser blood
irradiation and an immunomodulatory antiseptic agent. Biochemical markers,
including lipid hydroperoxides (LOOH), catalase activity, and interleukins (IL-
1β, IL-2, IL-6), were assessed before and after treatment. The main group
showed significant improvements in oxidative stress and cytokine profiles,
confirming the superiority of the integrated treatment.

Introduction:
Chronic kidney disease (CKD) is a systemic condition known
to affect multiple organ systems, including the oral cavity. Patients with CKD are
particularly susceptible to inflammatory conditions of the oral mucosa, such as
desquamative gingivitis, glossitis, and candidiasis. These manifestations often
result from a combination of xerostomia, altered mineral metabolism, and a
compromised immune system. The imbalance between oxidative and
antioxidative mechanisms plays a central role in the pathogenesis of these oral
lesions. Elevated levels of reactive oxygen species (ROS) and lipid peroxidation
products like lipid hydroperoxides (LOOH) contribute to tissue damage,
inflammation, and impaired healing.
Recent therapeutic strategies have emphasized the importance of targeting
oxidative stress and modulating inflammatory mediators to enhance clinical
outcomes. In this context, low-level laser blood irradiation (LLLI) has emerged
as a promising technique due to its potential to stabilize cellular membranes,
improve microcirculation, and normalize redox balance. When combined with

locally applied antiseptic agents possessing immunomodulatory properties, this
approach may offer synergistic benefits.
This study aims to assess the biochemical and immunological outcomes of a
combined therapy approach for treating oral mucosal inflammation in CKD
patients.
Materials and Methods:
A total of 100 CKD patients with clinically diagnosed inflammatory diseases
of the oral mucosa were enrolled. Patients were randomly divided into two
groups:
Control group (n=50): Received standard therapy, including antiseptic
rinses and anti-inflammatory medications.
Main group (n=50): Received the same treatment plus low-level laser
blood irradiation and a topical immunomodulatory antiseptic.
Laser Therapy Protocol:
A 635 nm low-intensity laser was used for
intravenous irradiation. Each session lasted 10 minutes, with a total of 10
sessions administered over two weeks.
Antiseptic Therapy:
Topical antiseptics were applied as mouth rinses
three times daily for 14 days. Agents used included chlorhexidine-based
solutions and immunomodulatory formulations.
Biochemical Assessments:
Lipid hydroperoxides (LOOH):
Measured in plasma and saliva via
spectrophotometry.
Catalase activity:
Determined by assessing H2O2 degradation capacity.
Cytokine levels (IL-1β, IL-2, IL-6):
Measured using ELISA.
Samples were collected in the morning before eating. Saliva was obtained
unstimulated over 10 minutes.
Statistical Analysis:
Data were analyzed using STATISTICA 6.0. Results
were expressed as mean ± SD. Student's t-test was used to compare pre- and
post-treatment values, with p<0.05 considered significant.
Results:
Oxidative Stress Markers:
Initial LOOH levels were elevated in both
groups compared to healthy controls (normal: 1.15 ± 0.08 OD units/ml).
Baseline levels were 2.89 ± 0.12 in the control and 2.91 ± 0.11 in the main group.
Post-treatment levels decreased to 2.05 ± 0.09 (control, p<0.05) and 1.48 ± 0.07
(main, p<0.001), indicating a more pronounced reduction in the main group.
Antioxidant Defense:
Catalase activity, initially below normal in both
groups (normal: 20.1 ± 1.6 mkat/L), increased from 8.94 ± 0.62 to 12.87 ± 0.84

in the control group (p<0.05), and from 9.01 ± 0.65 to 16.23 ± 0.79 in the main
group (p<0.01), reflecting enhanced antioxidant activity with combined therapy.
Cytokine Profiles:
IL-1β:
Decreased from 5.41 ± 0.39 to 4.32 ± 0.27 (control, p<0.05) and to
3.06 ± 0.21 (main, p<0.01).
IL-6:
Decreased from 5.88 ± 0.51 to 4.12 ± 0.35 (control, p<0.05) and to
2.79 ± 0.26 (main, p<0.001).
IL-2:
Increased from 5.62 ± 0.49 to 7.98 ± 0.54 (control, p<0.05) and to
9.82 ± 0.61 (main, p<0.01), indicating immune recovery.
This diagram illustrates the dynamics of key biochemical and
immunological markers in CKD patients with oral mucosal inflammation before
and after treatment. Four subgroups are presented: Control Before, Control
After, Main Before, and Main After. Significant improvements were observed in
the main group (combined therapy) in lipid peroxidation levels (LOOH), catalase
activity, and cytokines (IL-1β, IL-6, IL-2), indicating reduced oxidative stress and
inflammation and improved immune response. These findings support the
biochemical effectiveness of combining laser blood irradiation with antiseptic
and immunomodulatory therapy.
Discussion:
This study highlights the biochemical and immunological
benefits of integrating laser therapy with topical antiseptic agents in CKD
patients with oral mucosal inflammation. The notable reductions in LOOH and
pro-inflammatory interleukins, along with improved catalase activity and IL-2

levels, suggest a dual mechanism of action: attenuation of oxidative stress and
immune restoration. The results align with previous reports on the effectiveness
of LLLI in modulating ROS and cytokine production.
Importantly, the findings underscore the clinical utility of combining
systemic and local interventions to address the complex pathophysiology of oral
diseases in CKD patients. Such an approach could reduce recurrence, accelerate
healing, and improve patient quality of life.
Conclusion:
The combination of laser blood irradiation and
immunomodulatory antiseptic therapy significantly enhances oxidative balance
and cytokine regulation in CKD patients with oral mucosal inflammation. These
results support the adoption of this integrated strategy in routine dental and
nephrological care.
