Spots Global Cancer Trial Database for Intralesional Tetracycline Injection in the Treatment of Chalazia

Study Description

Brief Summary: The investigators propose a study to investigate the role of tetracycline injection into chalazia versus observation alone. The investigators hypothesize tetracycline injection will result in a significant decrease in lesion size when compared to observation alone.

Detailed Description: Intralesional Tetracycline Injection in the Treatment of Chalazia Authors: Bryan R. Costin, M.D. and Julian D. Perry, M.D. Purpose: To investigate the therapeutic role of intralesional tetracycline injection when compared to observation alone in the treatment of chalazia. Introduction: The tetracycline family includes tetracycline, doxycycline, and minocycline and this group of compounds has a surprising number of properties including but not limited to antibiotic, anti-malarial, anti-inflammatory, and antioxidant. Recent applications include uses both in sclerotherapy in a wide variety of conditions from ganglions cysts to lymphangiomas to ovarian cysts as well as in the reduction of hypertrophic scarring in rabbit models.1,2,3,4 In 2009, there were approximately 130 ongoing clinical trials studying this class of drugs in an astounding variety of conditions from gingivitis to Alzheimer disease to brain cancer.5 Chalazia are lipogranulomatous inflammatory lesions of the eyelid and are one of the most common eyelid lesions and an extremely frequent presenting complaint to the ophthalmologist. Chalazia often represent significant morbidity for the patients suffering from these lesions because they are often recurrent, can be refractory to treatment, and are disfiguring. Consequently, chalazia can also be a challenge to the ophthalmologist. Oral tetracyclines have been shown to be effective in the treatment of ocular rosacea and meibomian gland dysfunction (MGD), which are conditions commonly seen in association with chalazia. The anti-inflammatory effect of the tetracyclines is thought to be beneficial in rosacea and these drugs have been shown to alter the fatty acid composition of the lipid layer of the tear film perhaps explaining their efficacy in MGD.6 Chalazia eventually resolve without intervention, but the process can take many months and patients are frequently dissatisfied with observation as a treatment modality. Often patients choose incision and drainage (I\&D) of the lesion and this method is often successful. Another treatment shown to be effective in chalazion treatment is the injection of corticosteroid directly into the lesion, hence providing a depot anti-inflammatory effect.7 However, unlike corticosteroids, the tetracyclines would offer antibiotic, sclerosant, and lipid tear film augmentation, in addition to their anti-inflammatory effect. Further, tetracyclines are FDA approved for the treatment of acne8, which is defined as inflammation of pilosebaceous units9, and chalazia are defined as inflammation of sebaceous glands10. With these multiple roles in mind, we propose injection of tetracycline into chalazia to investigate its use as a multipurpose depot. Methods: After IRB approval, chalazia patients who wish to participate will be enrolled after the risks, benefits, alternatives, and personnel have been explained to them and informed consent has been obtained. A total of 80 subjects will be randomized to one of two groups: 40 subjects to observation alone and 40 subjects to treatment with an intralesional injection of 0.05 mL 2% tetracycline solution. Subjects will be excluded from the study if they are less than 18 years of age, are pregnant, have chalazia of less than 1 week duration, have known allergies to tetracycline or its derivatives, or are currently taking oral tetracyclines or have taken them in the past 3 months. Men, post-menopausal women, and women who have undergone hysterectomy, bilateral oophorectomy, or bilateral salpingectomy will not be tested for pregnancy. Pregnancy testing (urine or serum) will be performed on women of childbearing age before enrollment and the results checked prior to the administration of treatment. For patients with multiple lesions, either on the same or opposite eyelids, only the most symptomatic lesion will be enrolled in the study. Eyelid margin disease and ocular rosacea will be documented at the time of enrollment. Subjects will then be examined at 4 weeks (+/- 2 weeks) post-procedure follow-up visits where data regarding lesion size, including color photography, lesion regression or recurrence, and a complete ophthalmic examination will be recorded. If subjects fail to follow up at any of these visits, telephone interviews will be conducted. At the time of enrollment, the subject's date of birth, sex, race/ethnicity, and last menstrual period will be determined as well as a gynecological history to determine need for pregnancy testing. Data collection sheets will be used to record information. Also, previous therapies including topical medications and previous surgeries will be reviewed. A millimeter ruler will be used at the time of enrollment to determine the size of the lesion. Lesion photographs will also be taken so that the independent chalazion photograph reviewer will be able to grade degrees of improvement after treatment in a masked fashion. When the procedure is performed, a variable pain scale will be used by the patient to document their level of discomfort during the injection. At the return post procedure visit, the lesion will be re-measured, the patient will be asked to grade the level of improvement and a follow up photograph will be taken for use by the masked grader. All data collection sheets and consents will be stored at the Cleveland Clinic in a secure location. All other study data will be electronic and stored only on the secure Cleveland Clinic server or Cleveland Clinic issued encrypted devices such as thumb drives and laptops. The occurrence of any minor adverse or unexpected events will be reported to the principal investigator. Any sentinel events will be reported to the IRB immediately. A decrease in lesion size by two-thirds of greater as determined by either the clinician or the masked photograph reviewer in either group will be considered improvement and if seen in lesions injected with tetracycline it will constitute treatment success.
