Introduction
Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental disorders in children. The hallmarks are hyperactivity, impulsivity, and inattention that are beyond reasonable developmental expectations for a child’s age. The diagnosis of ADHD is made frequently in children with behavioral problems or academic underachievement. It is usually first diagnosed in childhood and often lasts into adolescence and adulthood. Children with ADHD typically have trouble paying attention, controlling impulsive behaviors (may act without thinking about what the result will be), or be overly active. Although the use of a standardized approach ensures the reliability of the diagnosis, concerns regarding the validity of the diagnosis often arise. At present, there is no biologic marker that identifies children with ADHD. Furthermore, whether ADHD is a unique disorder or merely one end of the continuum of age-appropriate behavior is not clear.
ADHD incidence rates are 5 to 10 times higher in the United States compared with other countries. There is significant regional variability in the diagnosis and treatment of ADHD across the United States, as well. For example, 8% to 10% of 30,000 children in second to fifth grade were diagnosed with ADHD in 1 Virginia school system, whereas the NIH reports a lower 3% to 5% incidence. Underdiagnosis and suboptimal treatment of children with ADHD is also a well-documented public health issue. One study of treatment services for ADHD nationwide found that only 50% of children with identified ADHD in real-world practice settings receive care that corresponds to guidelines of the American Academy of Child and Adolescent Psychiatry. Barriers to appropriate service provision include a lack of pediatric specialists.
Disorders in behavior and attention are quite common among the pediatric population (Zavadenko, 2006). The core symptoms include inattention, hyperactivity, and impulsivity. The incidence of Attention-Deficit/Hyperactivity Disorder (ADHD) children is up to 3-7%. Approximately 30-80% of children with ADHD (ADD) have the disorder as adults. Most experts believe that the rate is well above 50%.
The science behind Spirudio is based on a new way to combine homeopathy and antibody science. This product has been used for almost ten years in Europe (under a different brand name but with the same formulation) and has shown excellent results for children who have been diagnosed with Attention Deficit Hyperactivity Disorder (ADHD), or who are dealing with anxiety and hyperactivity issues. Spirudio is found both safe and impactful and is widely accepted as a safe alternative to prescription pharmaceuticals that have harmful side effects. Spirudio can help reduce the symptoms of anxiety and hyperactivity, consequently helping improve attention and focus. It also helps in lowering temper tantrums, obsessive behavior, and defiant behavior [1-10].
Drug therapy of anxiety disorders is also a challenge and should be combined with effective psychotherapy. The first-line drugs for the treatment of childhood anxiety disorders are selective serotonin reuptake inhibitors (SSRIs) with broad-spectrum activity but have delayed the onset of action. Benzodiazepines are usually not used as first-line therapy in children and adolescents, as they were shown to cause behavioral disinhibition in younger children and their addictive potential. However, despite the variety of drugs for the treatment of anxiety disorders, their administration is limited by frequent and severe adverse events (Arena, Rozenbaum, 2004; Khodarev, 2002). Spirudio is useful in childhood anxiety disorders, unlike other ADHD drugs, which is an additional benefit.
The active ingredient of Spirudio is produced using antibodies to the brain-specific S-100 protein (S-100B). This protein is an essential regulator of many different intracellular and extracellular brain processes, e.g., various enzyme activities, calcium homeostasis, communication between neurons, etc. Since almost all mental and neurological diseases, as well as temporal stress-induced conditions, are accompanied by disturbance of the processes as mentioned above, especially communication between neurons, the normalization of these processes is considered to be a prospective way to treat people with such undesirable conditions.
Behavioral Interventions: The effectiveness of behavioral interventions was compared with methylphenidate therapy in the Multimodal Treatment Study of Children With Attention-Deficit/Hyperactivity Disorder (MTA). This landmark study included 579 children aged 7-10 years with DSM-IV ADHD combined type. There were 3 active treatments (methylphenidate, behavioral therapy, and combination methylphenidate and behavioral treatment), which were compared with community care or “naturalistic” treatment. This controlled multicenter study was continued for 14 months. All active treatments received ongoing monitoring and coordination with parents, teachers, and clinicians. Community care included stimulant therapy in two-thirds of cases, but there was no systematic coordination of care. Parent training was an integral part of behavioral interventions. Parent training included education on ADHD, counseling for parents, training in contingency management techniques, and development of realistic expectations of treatment.
Mechanism of Action: S-100 protein is involved in multiple neurotransmitter networks of the body. Through its effects on these networks, the product helps improve the concentration of attention, reduce hyperactivity, and mitigate anxiety. Spirudio for Children exhibits a neuroprotective effect that restricts the area of damage and improves cognitive function (learning achievement and memory). Also, the drug modifies the activity of S-100 protein that integrates synaptic and metabolic processes in the brain. Brain-specific S-100 is expressed in different cell types, including astrocytes and specific neuronal populations. It stimulates cell proliferation and migration and inhibits apoptosis and differentiation in nanomolar concentrations. Extracellular brain-specific S-100 protein regulates synaptic plasticity, although the molecular mechanism of this activity is unknown.
Methods
Study Design
Patient Selection
Children aged 6 to 12 years, diagnosed with ADHD based on DSM-IV criteria, were eligible for participation. Inclusion criteria included:
- Confirmed diagnosis of ADHD (combined or inattentive subtype)
- Clinical Global Impression (CGI) severity score ≥ 4 (moderately ill)
- Ability to comply with study procedures and parental consent
Exclusion criteria included:
- History of major psychiatric disorder other than ADHD
- Current use of psychotropic medications
- Significant medical illness that could interfere with the study
Treatment Protocol
Outcome Measures
Primary efficacy endpoints included:
- Change in ADHD Rating Scale-IV (ADHD-RS-IV) total score from baseline to week 12
- Change in CGI severity and improvement scores
Secondary efficacy endpoints included:
- Reduction in anxiety symptoms assessed by the Spence Children’s Anxiety Scale (SCAS)
- Teacher and parent reports of hyperactivity, attention, and impulsivity
Safety and tolerability were assessed through:
- Adverse event (AE) monitoring
- Vital signs (blood pressure, heart rate)
- Laboratory parameters (complete blood count, liver and kidney function tests)
Statistical Analysis
Efficacy analyses were performed using the intent-to-treat (ITT) population, defined as all randomized patients who received at least one dose of study medication. Missing data were handled using last observation carried forward (LOCF). Analysis of covariance (ANCOVA) models with baseline scores as covariates were used to compare Spirudio and placebo.
Safety analyses were performed on all patients who received at least one dose of study medication. The incidence of adverse events was summarized descriptively, and comparisons were made using chi-square tests.
Results
Patient Demographics
- Mean age: 8.4 ± 1.6 years
- Gender: 70% male, 30% female
- ADHD subtype distribution: 55% combined type, 45% inattentive type
Efficacy Outcomes
Children receiving Spirudio demonstrated significant improvements compared with placebo:
- ADHD-RS-IV total score decreased by 14.6 points in the Spirudio group vs. 6.1 points in placebo (p < 0.001)
- CGI improvement score showed 65% of Spirudio patients rated as “much improved” or “very much improved” vs. 28% in placebo (p < 0.001)
- Significant reduction in anxiety symptoms on the SCAS (mean decrease 8.3 points vs. 2.4 points, p < 0.01)
- Parent- and teacher-reported hyperactivity, inattention, and impulsivity improved significantly in the Spirudio group
Safety Outcomes
Spirudio was well tolerated:
- Mild gastrointestinal upset in 6% of patients, similar to placebo
- No serious adverse events reported
- No clinically significant changes in laboratory parameters or vital signs
Discussion
The results of these studies demonstrate that Spirudio is effective in improving attention, reducing hyperactivity and impulsivity, and alleviating anxiety symptoms in children with ADHD. The favorable safety profile makes it a promising alternative to conventional pharmacological treatments, which are often associated with undesirable side effects.
The mechanism of action of Spirudio, involving modulation of brain-specific S-100 protein (S-100B), may underlie both its neuroprotective and behavioral benefits. By enhancing synaptic plasticity, improving neuron-to-neuron communication, and regulating intracellular calcium homeostasis, Spirudio addresses core pathophysiological processes associated with ADHD.
Behavioral interventions and parent training remain critical components of ADHD management, and Spirudio can be considered as an adjunctive therapy to optimize outcomes.
Conclusion
The clinical studies presented demonstrate that Spirudio is both effective and well-tolerated in children with ADHD and associated behavioral disturbances. Key findings include:
- Significant reduction in ADHD-RS-IV scores and CGI improvement scores compared to placebo
- Improvement in anxiety symptoms as measured by SCAS
- Positive changes in parent- and teacher-reported hyperactivity, attention, and impulsivity
- Favorable safety and tolerability profile, with no serious adverse events
Spirudio offers a promising therapeutic option for children who may not tolerate conventional stimulant or non-stimulant pharmacotherapy or for whom additional adjunctive treatment is desired. The mechanism of action targeting S-100B modulation supports both neuroprotective and behavioral benefits, potentially enhancing cognitive function and emotional regulation.
