A Patient with CVID

Case study for review:

Sarah Thompson, a 32-year-old elementary school teacher, presents to the immunology clinic with a history of recurrent and severe infections since childhood. Over the past few years, her infections have become more frequent and prolonged, leading to increased absenteeism from work and a significant decline in her overall quality of life.

Medical History:

• As a child, Sarah experienced frequent upper respiratory tract infections, ear infections, and sinusitis.
• During her teenage years, she was diagnosed with bronchitis on multiple occasions.
• In her early twenties, she developed a severe case of pneumonia that required hospitalization.
• She has a history of multiple skin infections, including cellulitis.
• Sarah reports a few episodes of meningitis-like symptoms, but these were not confirmed through lumbar punctures.

 Family History: There is no significant family history of immune disorders or other relevant medical conditions.

 Social History: Sarah is a non-smoker and consumes alcohol occasionally. She lives with her partner and has no history of substance abuse.

 Physical Examination:

• Vital signs are within normal limits.
• General appearance: Sarah appears tired and fatigued.
• Skin: Evidence of healing skin lesions present.
• Respiratory system: Slight wheezing and rhonchi upon auscultation.
• Other systems: No significant abnormalities noted.

Diagnostic Workup:

1. Complete Blood Count (CBC): Within normal limits.
2. Immunoglobulin Levels:
   • IgG: Significantly reduced levels.
   • IgA: Undetectable.
   • IgM: Normal.
3. Lymphocyte Subsets:
   • CD3 (T cells): Normal.
   • CD4 (T-helper cells): Normal.
   • CD8 (T-cytotoxic cells): Normal.
   • CD19 (B cells): Significantly reduced levels.
   • CD16/56 (Natural killer cells): Normal.
4. Flow Cytometry: Abnormal B cell maturation pattern.
5. Chest X-ray: Shows evidence of bronchiectasis.
6. Sinus X-ray/CT: Sinus opacification and chronic inflammation.

Diagnosis: Based on the clinical presentation, lab results, and diagnostic workup, Sarah is diagnosed with Common Variable Immunodeficiency (CVID), a primary immunodeficiency disorder characterized by defective antibody production, leading to recurrent and severe infections.

Consider the following statements/questions as you review the grading rubric for required content:

1. Discuss Sarah’s previous medical history across her lifetime as it relates to the diagnosis of Common Variable Immunodeficiency (CVID).
2. Describe the pathophysiology of CVID. Include a detailed discussion of the specific immunoglobulins that are used to make a diagnosis of CVID.  How do they impact the patient’s recurrent infections?
3. Provide a treatment plan for Sarah.  Include the primary goal for managing the disease and the components of the plan to improve Sarah’s quality of life. Be sure to also include how immunoglobulin replacement therapy and other interventions, including pharmacotherapeutics, will be used to improve her condition.  What potential side effects or adverse effects are possible with medication treatment? How will you include Sarah’s partner & family in the plan? What are the implications of her workplace on her diagnosis & plan? What psychosocial concerns may need to be addressed?
4. What are the potential complications that can arise from CVID and how might they impact the patient’s overall health?  What are the specific ways these complications can be avoided or managed?
5. Discuss Sarah’s prognosis and any education you would provide to the patient. Consider any safety considerations to improve Sarah’s quality of life.
