Antiphospholipid Syndrome in a Male Patient Presenting with Abdominal Pain

Abstract

Introduction: Antiphospholipid syndrome (APS) is a systemic autoimmune disorder characterized by antiphospholipid antibodies (aPL), leading to a hypercoagulable state and an increased risk of thrombotic events. While abdominal complications have been reported as the initial presentation of APS in some cases, these instances are predominantly observed in female patients. Here, we present a case of a 49-year-old male patient who presented with complaints and a CT scan mimicking intestinal ileus. However, no mechanical or other evident cause of ileus could be found on the explorative laparotomy. After an uneventful postoperative hospitalization and being discharged in good condition, the patient was readmitted within two weeks, and this time, an extensive small bowel resection due to ischemia was done. After going home in a good and stable condition, he presents again, but this time with cerebral ischemia. Further investigations led to the APS diagnosis. With this case, we want to emphasize the importance of being aware of and considering the diagnosis of APS, especially in cases with repeated, unexplained abdominal pain and non-typical complaints, even in male patients. An early diagnosis could prevent a more complex disease complication. Conclusion: This case underscores the importance of considering APS in the differential diagnosis of unexplained abdominal pain, particularly in male patients with a history of thrombotic events or elevated aPL levels. Heightened awareness of APS in the emergency setting can facilitate timely diagnosis and appropriate management, ultimately optimizing patient care and outcomes.
