ICD-10: M02.16

Postdysenteric arthropathy, classified under ICD-10 code M02.16, refers to a type of arthritis that occurs following an episode of dysentery, which is typically caused by bacterial infections such as Shigella or Entamoeba histolytica. The diagnosis of postdysenteric arthropathy involves several criteria, which can be categorized into clinical, laboratory, and imaging findings.

Clinical Criteria

1. History of Dysentery: A confirmed or suspected history of dysentery is essential. This may include symptoms such as diarrhea, abdominal pain, and fever, typically occurring prior to the onset of arthropathy.

2. Joint Symptoms: Patients usually present with joint pain, swelling, and stiffness, particularly in the knee. The symptoms may develop within weeks to months after the dysentery episode.

3. Exclusion of Other Causes: It is crucial to rule out other forms of arthritis, such as rheumatoid arthritis, osteoarthritis, or other inflammatory arthropathies, to confirm that the joint symptoms are indeed postdysenteric in nature.

Laboratory Criteria

1. Serological Tests: Blood tests may be conducted to identify markers of inflammation, such as elevated C-reactive protein (CRP) or erythrocyte sedimentation rate (ESR). However, these tests are nonspecific and should be interpreted in conjunction with clinical findings.

2. Microbiological Tests: If available, stool cultures or serological tests can help confirm a previous infection with dysentery-causing organisms. This is particularly relevant if the dysentery episode was recent.

Imaging Criteria

1. Radiological Examination: Imaging studies, such as X-rays or MRI of the knee, may be performed to assess joint damage or inflammation. These studies can help visualize any changes consistent with inflammatory arthritis.

2. Joint Aspiration: In some cases, aspiration of the knee joint may be performed to analyze synovial fluid. This can help rule out other conditions, such as septic arthritis or gout.

Conclusion

The diagnosis of postdysenteric arthropathy (ICD-10 code M02.16) is primarily based on a combination of clinical history, joint symptoms, laboratory findings, and imaging studies. A thorough evaluation is necessary to differentiate it from other arthropathies and to confirm the link to a prior dysentery episode. Proper diagnosis is crucial for effective management and treatment of the condition.

Postdysenteric arthropathy, classified under ICD-10 code M02.16, refers to a specific type of arthritis that occurs following a dysentery infection. This condition primarily affects the knee joint and is characterized by inflammation and pain resulting from the body's immune response to the dysentery-causing pathogens.

Clinical Description

Definition

Postdysenteric arthropathy is a reactive arthritis that develops after an episode of dysentery, which is typically caused by bacterial infections such as Shigella or Entamoeba histolytica. The condition is classified as a type of inflammatory arthritis, where the immune system mistakenly attacks the joints after the initial infection has resolved.

Symptoms

Patients with postdysenteric arthropathy may experience:
- Joint Pain: Primarily localized in the knee, but can also affect other joints.
- Swelling: Inflammation around the affected joint, leading to visible swelling.
- Stiffness: Reduced range of motion in the knee joint, particularly after periods of inactivity.
- Warmth and Redness: The affected area may feel warm to the touch and appear red.

Diagnosis

Diagnosis of postdysenteric arthropathy typically involves:
- Medical History: Reviewing the patient's history of dysentery and any related gastrointestinal symptoms.
- Physical Examination: Assessing joint tenderness, swelling, and range of motion.
- Laboratory Tests: Blood tests may be conducted to check for markers of inflammation and to rule out other types of arthritis.

Postdysenteric arthropathy, classified under ICD-10 code M02.16, is a type of reactive arthritis that occurs following an episode of dysentery, typically caused by bacterial infections such as Shigella or Campylobacter. This condition primarily affects the joints, particularly the knee, and is characterized by a range of clinical presentations, signs, and symptoms.

Clinical Presentation

Onset and Duration

Postdysenteric arthropathy usually develops within a few weeks after the initial gastrointestinal infection. The onset can be acute, with patients experiencing sudden joint pain and swelling, or it may present more gradually. The duration of symptoms can vary significantly, with some patients experiencing persistent symptoms for months or even years, while others may have a more transient course.

Affected Joints

While the knee is the most commonly affected joint in postdysenteric arthropathy, other joints may also be involved, including the ankles, wrists, and fingers. The involvement of multiple joints is not uncommon, and the condition can manifest as either monoarthritis (affecting one joint) or oligoarthritis (affecting a few joints).

Signs and Symptoms

Common Symptoms

1. Joint Pain: Patients typically report significant pain in the affected joints, which may be exacerbated by movement or weight-bearing activities.
2. Swelling: The affected knee may exhibit noticeable swelling due to inflammation.
3. Stiffness: Morning stiffness or stiffness after periods of inactivity is common, impacting the range of motion.
4. Redness and Warmth: The skin over the affected joint may appear red and feel warm to the touch, indicating inflammation.

Systemic Symptoms

In addition to joint-specific symptoms, patients may experience systemic manifestations such as:
- Fever: A low-grade fever may accompany the joint symptoms, particularly during the acute phase.
- Fatigue: Generalized fatigue and malaise are common, reflecting the body’s response to inflammation.

Patient Characteristics

Demographics

Postdysenteric arthropathy can affect individuals of any age, but it is more frequently observed in young adults and middle-aged individuals. There may be a slight male predominance in cases of reactive arthritis.

Risk Factors

• Recent Gastrointestinal Infection: A history of dysentery or gastrointestinal infection is a significant risk factor for developing postdysenteric arthropathy.
