Efficacy assessment of intravenous immunoglobulin for gastrointestinal involvement in systemic sclerosis using UCLA SCTC GIT: Case-based review. | LitMetric

Objectives: To summarize the published evidence in the literature on the use of intravenous immunoglobulin in gastrointestinal tract involvement in systemic sclerosis patients and report the experience of our department.

Methods: A systematic literature review was performed; and a literature search was conducted in MEDLINE and Embase until 1/5/2024, using the participants, intervention, comparator and outcomes framework. Only full-text articles involving systemic sclerosis adults, submitted to intravenous immunoglobulin (at least one administration) to treat primary gastrointestinal tract manifestations. The outcome was the University of California at Los Angeles Scleroderma Clinical Trial Consortium Gastrointestinal Tract 2.0 score to evaluate response to treatment. Two reviewers performed the assessment of data extraction and synthesis, independently.

Results: Four papers (two case reports and two retrospective studies) out of 35 references were included. In addition, we added two systemic sclerosis patients from our department in this review. In 25 systemic sclerosis patients, with various gastrointestinal tract manifestations, the intravenous immunoglobulin therapy was found to improve digestive tract symptoms in SSc patients, as shown by the decrease in the scores of University of California at Los Angeles Scleroderma Clinical Trial Consortium Gastrointestinal Tract 2.0. No adverse events were reported, except for one case of low-grade fever post-administration.

Conclusion: The results from this systematic literature review based on case series suggest that intravenous immunoglobulin may improve gastrointestinal tract symptoms assessed by the University of California at Los Angeles Scleroderma Clinical Trial Consortium Gastrointestinal Tract 2.0 scale, with only minor reported adverse events, suggestive of an acceptable safety profile. We believe that this systematic literature review will contribute to shed light on the efficacy and safety aspects of intravenous immunoglobulin treatment in the management of gastrointestinal tract symptoms; and multicenter randomized placebo-controlled trials are urgently needed to foster progress in this field.
