Treatment With Octreotide in Patients With Lymphangioleiomyomatosis

Lymphangioleiomyomatosis (LAM), a disease primarily of women of child-bearing age, is
characterized by cystic lung disease and abdominal tumors (e.g., angiomyolipomas). Within
the LAM patient population is a subset of patients who develop chylous ascites, chylous
pleural effusions, chyluria, peripheral lymphedema, and/or lymphangioleiomyomas.
Lymphangioleiomyomas are believed to result from a proliferation of abnormal smooth muscle
cells within the lymphatic system, which appears to obstruct fluid outflow, leading to fluid
accumulation and an increase in size. The lymphangioleiomyomas may occur anywhere along the
axial lymphatic chain. In patients with LAM, they occur most frequently in the thorax,
abdomen and pelvis and may give rise to a myriad of symptoms (e.g., paresthesias,
palpitations, peripheral edema). In some patients, treatment of many of these symptoms,
i.e., elevation of lower extremities, paracentesis, thoracentesis, diuretics, and/or
surgery, has been ineffective. Previous studies with somatostatin and octreotide in other
clinical settings (e.g., traumatic damage to the lymphatics) have shown a successful
reduction in chylous effusions, chyluria, ascites, and peripheral lymphedema, when other
therapies were less effective. This study will assess the effectiveness of octreotide in
symptomatic patients with LAM, lymphangioleiomyomas and/or chylous effusions/ascites,
peripheral lymphedema and chyluria. The dose of octreotide starts at 50 micrograms (ug) by
the subcutaneous route twice a day. After two weeks the dose will be increased to 200 ug per
day and two weeks later to 400 ug/day. Maximal dose is 400 ug twice a day.

Inclusion Criteria


Patients enrolled in the lymphangioleiomyomatosis natural history protocol who have
symptoms associated with one of the following:

1. lymphangioleiomyomas

2. chylous pleural effusions

3. peripheral lymph-edema

4. chyloptysis

5. protein-losing enteropathy

6. chyluria

Patients will be included in this protocol if symptoms are attributed to the above
processes. Patients with malabsorption disorders, diabetes, hypo/hyperthyroidism, or
other endocrine-related disorders will be included if justified clinically based on
severity of symptoms.


1. Hypersensitivity to somatostatin, octreotide or its analogues

2. Patients with hepatitis B, hepatitis C, or other clinically significant liver

3. Transplant patients

4. Pregnant women or women who are beast-feeding

5. Patient or another responsible party is unable to give the subcutaneous injection

6. Patient unwilling to be followed per the guidelines set forth

7. Patients with decreased renal function (creatinine greater than 1.5)

8. Patients with HIV infection

9. Immunosuppressed patients
