Overview
This study evaluates the change of insulin resistance and glucose metabolism of patients with panniculitis associated acquired lipodystrophy syndrome and type 1 diabetes with the treatment of cyclophosphamide.
Description
Patients with panniculitis associated acquired lipodystrophy syndrome and type 1 diabetes have difficulty in blood glucose management due to the presence of both severe insulin resistance and complete insulin deficiency. It is often necessary to use insulin doses several times that of other children of the same age with type 1 diabetes.
Since autoimmune response is the main cause of panniculitis associated acquired lipodystrophy syndrome, immunosuppressive agents can suppress immune response, prevent and alleviate the progression of panniculitis and acquired lipodystrophy syndrome, and improve insulin resistance caused by subcutaneous fat deficiency.
Cyclophosphamide is a classic immunosuppressive agent. This study hopes to improve insulin resistance of patients with panniculitis associated acquired lipodystrophy syndrome and type 1 diabetes by cyclophosphamide treatment, thereby reducing insulin dosage and improving glucose metabolism.
Eligibility
Inclusion Criteria:
- Meet the diagnostic criteria of type 1 diabetes mellitus: clinical manifestations of typical diabetes mellitus include polyphagia, polyuria, weight loss, or diabetic ketoacidosis, confirmed by blood sugar level, islet function and autoimmune antibody.
- Meet the diagnostic criteria for panniculitis: fat biopsy suggests inflammatory infiltration.
- Meet the diagnostic criteria for acquired lipodystrophy syndrome: childhood onset, clinically no nutritional deficiency or catabolism, systemic or partial subcutaneous fat reduction, genetic testing to exclude congenital lipodystrophy syndrome; low leptin level and autoantibodies can aid in diagnosis.
Exclusion Criteria:
- Mature and effective treatment methods are available.
- HIV, HBV and HCV were positive.
- A the active period of infection.
- At the active stage of malignant tumors.
- Combination of other fatal diseases.
- Existence of mental and psychological diseases.
