Antibiotics vs Corticosteroids in Treatment of Granulomatous Lobular Mastitis

Granulomatous Mastitis

The goal of this clinical trial is to find the most effective and safe medical treatment for Granulomatous Lobular Mastitis (GLM) - a rare, chronic inflammatory breast disease that affects young and middle-aged women, often following childbirth. The main questions it aims to answer are: Does an antibiotic regimen (clarithromycin, ofloxacin, rifaximin) lead to faster and complete healing (Complete Clinical Response) compared to steroids? Do steroids (prednisolone in tapering doses) provide better symptom control or cause more side effects? Researchers will compare the antibiotic group (Group A) and the steroid group (Group B) to see which treatment results in quicker recovery, fewer side effects, and lower recurrence rates. Participants will: Receive a 14-day antibiotic trial initially (screening phase). If no improvement, be randomly assigned to: Group A (Antibiotic therapy) - Clarithromycin, Ofloxacin, Rifaximin for 8 weeks, or Group B (Steroid therapy) - Prednisolone in tapering doses for 8 weeks. Undergo evaluation after 2 months: If not fully recovered, receive Methotrexate + Folic acid for another 8 weeks. If still no improvement, switch to the alternate treatment or undergo surgery if required. Attend regular follow-ups for 6 months for clinical assessment and monitoring of side effects. This 2-year study aims to develop a standardized, step-by-step treatment protocol for GLM, helping improve outcomes and reduce unnecessary surgeries for affected women.

What is this study about? This research is being done at AIIMS Bhubaneswar to find the best medical treatment for a breast condition called Granulomatous Lobular Mastitis (GLM). GLM is a rare, long-lasting inflammation of the breast that mainly affects young and middle-aged women, often those who have recently had children. It can look very similar to breast cancer or a breast abscess, causing anxiety and sometimes unnecessary surgery. Common symptoms include: Painful or painless breast lump Swelling, redness, or abscess (collection of pus) Discharge from the nipple or retraction (nipple pulled inward) Skin changes over the breast It can occur in one or both breasts and may come back after treatment. Why is this study important? At present, there is no single, standard treatment for GLM. Doctors use antibiotics, steroids, immunosuppressants (like methotrexate), or surgery - but the results vary widely. Some medicines help one patient but not another, and some cause unwanted side effects or recurrences. This study aims to compare antibiotics and steroids directly, to identify which gives better and faster healing with fewer side effects. The goal is to develop a clear, step-by-step treatment plan for all patients with GLM. What will happen in this study? Who can take part? Women diagnosed with GLM by biopsy (tissue test). Participants must be willing to attend regular follow-ups. Women who are pregnant, breastfeeding, diabetic (uncontrolled), on other immunosuppressive treatment, or allergic to study drugs cannot participate. How the study works: First step (screening): All participants will receive a short course of antibiotics for 14 days. If the infection improves, treatment continues outside the study. If it doesn't improve, the person will be included in the main trial. Random assignment: Patients will be randomly divided into two groups: Group A - Antibiotic group: Receives clarithromycin, ofloxacin, and rifaximin tablets for 8 weeks. Group B - Steroid group: Receives prednisolone (steroid tablets) in reducing doses for 8 weeks. Review after 2 months: Doctors will check whether the breast swelling and pain are gone. If completely cured (called Complete Clinical Response or CCR), medicines are stopped. If not cured, the patient is given an additional medicine (methotrexate + folic acid) for 8 weeks. If still not improved: The treatment groups are switched (antibiotic patients receive steroids, and vice versa). If there's still no recovery, surgery (like abscess drainage or lump removal) will be considered. Throughout the study, symptoms, side effects, and any need for surgery will be recorded carefully. How long does participation last? Each participant will be followed for around 6 months - this includes treatment, monitoring, and follow-up visits. Possible benefits for participants Regular medical check-ups, follow-ups, and investigations by specialist doctors. Chance of receiving an effective, well-monitored treatment plan. Early detection of complications and quick medical management. Contribution to medical knowledge that may help future patients avoid prolonged or incorrect treatment. Possible side effects or risks All medicines used in this study are commonly prescribed and generally safe under supervision. However, possible side effects may include: For antibiotics: stomach upset, nausea, mild diarrhea, or allergy (rare). For steroids: weight gain, bloating, mood changes, increased appetite, or joint pain. For methotrexate: mild fatigue, nausea, or rare liver enzyme changes (monitored closely). Doctors will monitor all participants closely and adjust or stop treatment if any problems arise. Any abscess or fluid collection will be drained if needed, and pain will be managed with appropriate medicines. Confidentiality and voluntary participation All personal information will be kept strictly confidential. Participants' names will not appear in any reports or publications. Joining this study is completely voluntary. You may leave the study at any time without affecting your future medical care. Costs and compensation All investigations and medicines that are part of routine care are free or low-cost. The average expected expense is about ₹2500, which includes only the patient's regular medical costs. If any research-related injury occurs, the hospital will provide free treatment. Expected outcomes By comparing results between antibiotics and steroids, this study aims to: Identify which treatment helps more women achieve complete healing faster. Understand which drugs have fewer side effects. Reduce the need for surgery and recurrence. Develop a standardized treatment protocol for GLM. If antibiotics are found to be equally effective or better, they could become the first-line, low-cost, safer option - especially in areas with limited resources. If steroids prove superior, their dosage and duration can be refined to minimize side effects. Study time - 2 years
