Acute Compartment Syndrome and Intra-Abdominal Hypertension, Decompression, Current Pharmacotherapy, and Stable Gastric Pentadecapeptide BPC 157 Solution.
This review paper examines pharmacotherapies for abdominal compartment syndrome (ACS) and intra-abdominal hypertension (IAH) through the lens of cytoprotection theory, framing these conditions as failures of cytoprotective mechanisms. The authors survey existing pharmacological agents used in ACS/IAH management, noting that most currently reported treatments are limited in scope—typically effective in only one organ, tested only in mild-to-moderate IAH, applied prophylactically rather than therapeutically, and lacking confirmed broad effectiveness. The review then focuses on stable gastric pentadecapeptide BPC 157 as a proposed cytoprotective agent with claimed pleiotropic effects. The authors argue that BPC 157 may address multiple simultaneous targets in ACS/IAH, including compression/ischemia and decompression/reperfusion injury across several organs (brain, heart, lung, liver, kidney, gastrointestinal tract). A proposed mechanism involving activation of collateral "bypassing" vascular pathways—particularly azygos vein blood flow—is described as a potential key to counteracting multiorgan failure, vascular dysfunction, thrombosis, and free radical damage. The paper is a narrative review drawing primarily on animal study data; it does not present original clinical trial data or human evidence. Conclusions about BPC 157 efficacy are therefore speculative in a human clinical context.
Why this grade: This is a narrative review whose underlying evidence base for BPC 157 consists predominantly of animal studies, with no original human clinical trial data presented to support efficacy claims.
In this study, pharmacotherapies of abdominal compartment syndrome (ACS) and intra-abdominal hypertension (IAH) in animal studies were reviewed from the perspective of ACS/IAH as failed cytoprotection issues, as non-specific injuries, and from the point of view of the cytoprotection concept as resolution. Therefore, this review challenges the unresolved theoretical and practical issues of severe multiorgan failure, acknowledged significance in clinics, and resolving outcomes (i.e., open abdomen). Generally, the reported agents not aligned with cytoprotection align with current pharmacotherapy limitations and have (non-)confirmed effectiveness, mostly in only one organ, mild/moderate IAH, prophylactic application, and provide only a tentative resolution. Contrarily, stable gastric pentadecapeptide BPC 157 therapy, as a novel and relevant cytoprotective mediator having pleiotropic beneficial effects, simultaneously resolves many targets, resolving established disturbances, specifically compression/ischemia (grade III and grade IV), and decompression/advanced reperfusion. BPC 157 therapy rapidly activates collateral bypassing pathways, and, in ACS and IAH, and later, in reperfusion, there is a "bypassing key" (i.e., azygos vein direct blood flow delivery). This serves to counteract multiorgan and vessel failure, including lesions and hemorrhages in the brain, heart, lung, liver, kidney and gastrointestinal tract, thrombosis, peripherally and centrally, intracranial (superior sagittal sinus), portal and caval hypertension and aortal hypotension, occlusion/occlusion-like syndrome, advanced Virchow triad circumstances, and free radical formation acting as a membrane stabilizer and free radical scavenger. Likewise, not only in ACS/IAH resolving, but also in other occlusion/occlusion-like syndromes, this "bypassing key" could be an effect of the essential endothelial cytoprotective capacity of BPC 157 and a particular modulatory effect on the NO-system, and a rescuing impact on vasomotor tone.
