Symptoms of Juvenile Hypermobility Syndrome

The symptoms of JHS can vary widely in severity and may include:

Joint Hypermobility: The primary feature of JHS is the ability of joints to move beyond the normal range. This hypermobility is often most noticeable in the elbows, knees, fingers, and spine.

Joint Pain and Stiffness: Pain, especially after physical activity, is common in children with JHS. Stiffness can also occur, often after periods of inactivity.

Frequent Joint Dislocations and Subluxations: Due to the increased laxity of the ligaments, joints may partially or fully dislocate more easily.

Muscle Pain and Fatigue: The muscles may tire quickly and become painful due to the extra effort required to stabilize the hypermobile joints.

Frequent Sprains and Strains: The hypermobility can lead to a higher incidence of soft tissue injuries.

Poor Coordination and Balance: Children with JHS may experience difficulties with coordination and balance, leading to clumsiness or frequent falls.

Flat Feet: Overpronation or flat feet is a common feature due to the laxity of the ligaments in the feet.

Digestive Issues: Some children with JHS may experience gastrointestinal problems such as irritable bowel syndrome (IBS).

Diagnosis of HIDS

Diagnosing HIDS involves a combination of clinical evaluation, laboratory tests, and genetic analysis. Key diagnostic steps include:

Clinical Evaluation: A thorough medical history and physical examination to assess the pattern and characteristics of fever episodes, as well as other symptoms such as rash, abdominal pain, and lymphadenopathy.

Laboratory Tests:

Elevated IgD Levels: Measurement of immunoglobulin D (IgD) levels in the blood. Elevated IgD levels are a hallmark of HIDS, although they may not be elevated in all patients, particularly infants.

Urinary Mevalonic Acid: Elevated levels of mevalonic acid in the urine during fever episodes can support the diagnosis of HIDS.

Inflammatory Markers: Elevated levels of acute-phase reactants such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) during attacks.

Genetic Testing: Confirmatory diagnosis through genetic testing to identify mutations in the MVK gene. This test can definitively diagnose HIDS and distinguish it from other periodic fever syndromes.

What is Hyperimmunoglobulin D Syndrome?

Hyperimmunoglobulin D Syndrome, also known as Mevalonate Kinase Deficiency (MKD), is an autosomal recessive disorder caused by mutations in the MVK gene, which encodes the enzyme mevalonate kinase. This enzyme is critical for the biosynthesis of cholesterol and other isoprenoids, and its deficiency leads to the accumulation of intermediates that trigger inflammatory responses.
