Summary
Common variable immunodeficiency (CVID) increases infection and autoimmune risks. This report details a rare CVID case with relapsing polychondritis (RP) and chronic arthritis, highlighting a new association.
Area of Science:
- Immunology
- Rheumatology
- Clinical Medicine
Background:
- Common variable immunodeficiency (CVID) is a primary immunodeficiency characterized by impaired antibody production, leading to recurrent infections.
- Autoimmune manifestations are frequent in CVID, commonly including idiopathic thrombocytopenic purpura, autoimmune hemolytic anemia, chronic arthritis, and gastrointestinal inflammation.
- Relapsing polychondritis (RP) is a rare systemic inflammatory disorder targeting cartilage, typically affecting the ears, joints, and respiratory tract.
Observation:
- This report presents a unique case of a patient diagnosed with CVID.
- The patient also exhibited symptoms and diagnosis of relapsing polychondritis (RP).
- Chronic arthritis was another significant comorbidity observed in this CVID patient.
Findings:
- The case demonstrates a co-occurrence of CVID, relapsing polychondritis (RP), and chronic arthritis.
- This presentation suggests a potential, previously unreported association between CVID and RP.
- Autoimmunity to cartilage components, implicated in RP pathogenesis, may be linked to immune dysregulation in CVID.
Implications:
- This case expands the spectrum of autoimmune conditions associated with CVID.
- It underscores the importance of considering RP in CVID patients presenting with relevant symptoms.
- Further research is warranted to investigate the immunological mechanisms underlying the CVID-RP association.

01:25Immunodeficiency Diseases
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

01:29Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
01:23Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
01:25Inflammatory Bowel Disease III: Crohn's Disease
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
01:22Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
01:24Chronic Obstructive Pulmonary Disease
COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
