Disease Details
Family Health Simplified
- Description
- Immunodeficiency 31B is a rare genetic disorder characterized by a weakened immune system due to mutations in the DOCK8 gene, leading to increased susceptibility to infections and immune dysregulation.
- Type
- Immunodeficiency 31B (IMD31B) is a primary immunodeficiency disorder. It is transmitted in an autosomal recessive manner.
- Signs And Symptoms
-
Immunodeficiency 31B is a rare genetic disorder that affects the immune system. It can lead to recurrent infections and may present with various signs and symptoms, including:
- Frequent respiratory infections (such as pneumonia, bronchitis)
- Infections in other parts of the body (such as skin, ears, and sinuses)
- Failure to thrive or poor growth in children
- Chronic diarrhea
- Autoimmune disorders (where the immune system mistakenly attacks the body’s own tissues)
- Increased susceptibility to opportunistic infections
- Reduction in the number of B cells, T cells, or both, affecting the immune response
Diagnosis typically involves clinical evaluation, immunological tests, and genetic testing to confirm the underlying genetic defect. Treatment mainly focuses on managing infections and may include antibiotics, antiviral medications, and in some cases, immunoglobulin replacement therapy. - Prognosis
- Immunodeficiency-31b, caused by mutations in the NFKB2 gene, typically results in a range of immune-related issues, including recurrent infections, autoimmunity, and endocrine abnormalities. Prognosis can vary depending on the severity and specific disease manifestations. Early diagnosis and appropriate management with immunoglobulin replacement therapy and other supportive treatments can improve long-term outcomes. The prognosis is highly individualized, and regular monitoring by healthcare professionals is essential.
- Onset
- For immunodeficiency_31b (also known as COVID-19-related immunodeficiency 31b), "onset" is typically early childhood. This condition is characterized by a susceptibility to certain infections and immune system dysfunctions from a young age.
- Prevalence
- Immunodeficiency-31B (IMD31B) is an autosomal recessive primary immunodeficiency disorder. It is extremely rare, with only a few cases reported in the medical literature. Due to its rarity, specific prevalence data is not well-established.
- Epidemiology
-
Immunodeficiency 31B (also known as IMD31B) is a rare genetic disorder characterized by a primary immunodeficiency.
Epidemiology: The exact prevalence of IMD31B is not well established due to its rarity. It is an inheritable condition typically transmitted in an autosomal recessive pattern. This means that both parents must carry and pass on a defective gene for their child to be affected. Cases are sporadically reported across different populations.
"Epidemiology, nan" presumably refers to a classification or identifier within a particular database or context, but without additional context, a detailed response is not possible. - Intractability
- Immunodeficiency-31B is associated with mutations in the PIK3R1 gene. This primary immunodeficiency disorder can be challenging to treat due to its genetic basis and the resultant immune dysfunction. Although the condition is complex and often requires a multi-faceted treatment approach, including potential use of immunoglobulin replacement therapy and management of infections, it is not necessarily intractable. Advances in gene therapy and targeted treatments continue to improve outcomes for such genetic immunodeficiencies.
- Disease Severity
- Immunodeficiency-31B is characterized by an increased susceptibility to infections due to a compromised immune system. The severity of the disease can vary widely among individuals, ranging from mild to severe, and it is influenced by the specific genetic mutations and environmental factors affecting the individual.

- Pathophysiology
- Immunodeficiency-31B is a rare genetic disorder characterized by a compromised immune system. The pathophysiology involves mutations in the gene coding for the Signal Transducer and Activator of Transcription 3 (STAT3) protein. STAT3 is crucial for the signaling pathways that stimulate immune cell differentiation, proliferation, and function, particularly Th17 cells, which are important for fighting off fungal and bacterial infections. Mutations result in a deficiency or dysfunction of these immune responses, leading to increased susceptibility to infections and other immune-related complications.
- Carrier Status
- For immunodeficiency 31B, carrier status is not typically described as it primarily manifests as an autosomal recessive disease. This means that a person must inherit two defective copies of the gene, one from each parent, to exhibit the disease. Individuals with only one defective copy of the gene (carriers) generally do not show symptoms but can pass the gene to their offspring.
- Mechanism
-
Immunodeficiency-31B (IMD31B) is a primary immunodeficiency disorder characterized by defects in the immune system that lead to increased susceptibility to infections. The molecular mechanism behind IMD31B involves mutations in the NFKBIA gene, which encodes the IκBα protein.
**Mechanism:**
The IκBα protein normally acts as an inhibitor of the NF-κB signaling pathway, which is crucial for immune responses, inflammation, and cell survival. Under resting conditions, IκBα binds to NF-κB, sequestering it in the cytoplasm and preventing it from translocating to the nucleus to activate target genes.
**Molecular Mechanism:**
Mutations in NFKBIA associated with IMD31B typically lead to either a truncated or dysfunctional IκBα protein. This defective IκBα is unable to properly inhibit NF-κB. As a result, NF-κB may be constitutively active even in the absence of appropriate stimuli, leading to dysregulated immune responses. This dysregulation impairs the ability to mount effective responses against infections and may also affect inflammatory processes and cell survival pathways.
Overall, the failure to appropriately regulate NF-κB signaling due to defective IκBα underlies the immunodeficiency seen in IMD31B. - Treatment
-
Immunodeficiency 31b, also known as CARMIL2 deficiency, is characterized by a defect in the CARMIL2 gene affecting immune cell function. Treatment primarily focuses on managing infections and preventing complications. It includes:
1. **Antibiotics and Antivirals:** Used to treat bacterial and viral infections, respectively.
2. **Immunoglobulin Replacement Therapy:** Administered to boost the immune system.
3. **Hematopoietic Stem Cell Transplantation (HSCT):** Considered in severe cases to restore normal immune function.
4. **Prophylactic Antimicrobials:** Preventative use of antibiotics or antifungals to avoid infections.
5. **Supportive Care:** Includes routine monitoring, maintaining good hygiene, and managing symptoms on a case-by-case basis.
Consultation with an immunologist is essential for personalized treatment plans. - Compassionate Use Treatment
-
Immunodeficiency-31b (IMD31B), also known as DOCK8 deficiency, is a rare autosomal recessive disorder characterized by severe combined immunodeficiency, chronic eczema, and a high susceptibility to infections and malignancies.
### Compassionate Use Treatment
Compassionate use refers to the use of unapproved drugs outside of clinical trials for patients with serious or life-threatening conditions who have no other treatment options. For DOCK8 deficiency, bone marrow transplantation (BMT) or hematopoietic stem cell transplantation (HSCT) are often considered under compassionate use, particularly when no suitable donor is available in clinical trials.
### Off-label or Experimental Treatments
1. **Interleukin-2 (IL-2) Therapy**: Has been explored off-label to boost immune function, though its efficacy and safety profile for DOCK8 deficiency need more validation.
2. **Gene Therapy**: Experimental gene therapy approaches aim to correct the genetic defect in DOCK8. Research is ongoing, but it is not yet a standard treatment.
3. **Hematopoietic Stem Cell Transplant (HSCT)**: Although a standard treatment, different conditioning regimens and sources of stem cells (like haploidentical donors) can be considered experimental in some contexts.
4. **Targeted Therapies**: Use of targeted drugs like JAK inhibitors has moved into experimental stages to control inflammatory and autoimmune manifestations of the disease.
These treatments are at various stages of research and clinical application, emphasizing the importance of clinical judgment and ethical considerations. - Lifestyle Recommendations
-
For individuals with immunodeficiency-31b, some general lifestyle recommendations might be:
1. **Healthy Diet**: Maintain a balanced diet rich in fruits, vegetables, lean proteins, and whole grains to support overall immune health.
2. **Regular Exercise**: Engage in moderate physical activity, such as walking, swimming, or cycling, to enhance cardiovascular health and boost immune function.
3. **Adequate Sleep**: Ensure sufficient and quality sleep to help the body repair and strengthen the immune system.
4. **Hand Hygiene**: Practice regular hand washing with soap and water to reduce the risk of infections.
5. **Avoiding Sick Contacts**: Minimize exposure to individuals who are ill to reduce the chances of contracting infections.
6. **Vaccinations**: Follow a healthcare provider’s recommendations regarding vaccinations, which can provide additional protection.
7. **Stress Management**: Employ stress-reducing techniques such as meditation, yoga, or deep-breathing exercises to maintain mental well-being.
8. **Regular Check-ups**: Keep up with regular medical appointments for monitoring and managing the condition effectively.
