糖尿病性黄斑浮腫患者におけるラクティプランチバシラス・プランタルム 299v プロバイオティクス補充

Study Design: Prospective open label longitudinal interventional study with oral probiotic supplement Lactobacillus plantarum.

Inclusion criteria: Age of at least 18 years, presence of DME at the current clinical visit

Exclusion criteria: Patients with contraindication to probiotic supplement (e.g. prior allergy or GI intolerance and any type of immunocompromised diseases).

Eligible individuals (patients at least 18 years old with diabetic macular

Participants: Patients with DME that belong in the following two groups:

• Group A: 12 Patients with mild DME and good visual acuity (<= 20/30) similar to DRCR network protocol V that do not need anti-VEGF injections as per standard clinical care.
• Group B: 12 Patients with DME that need anti-VEGF injections as per standard clinical care.

Intervention: Oral probiotic supplement L. plantarum 299v twice daily for 4 months for both groups.

Study outcomes:

• OCT with central macular thickness (CMT) at 1, 2, 3, 4-months follow-up.
• Visual Acuity at 1, 2, 3, 4-months follow-up.
• Number of anti VEGF injections.

In group A, the percentage of patients with a stability or improvement in DME as determined by a stability (+/- 9% of OCT CMT) or a reduction of DME (>= 30 microns or >= 10% decrease of CMT) from baseline will be measured. Secondary endpoints will be visual acuity and need for injection initiation during the 4 months.

In group B, the same outcomes as in group A will be measured. Furthermore, the number of injections group A over the course of 4 months will be evaluated.

Data from both groups will be compared to historical data available at the study site.
