Recurrence of Multiple Gastrointestinal Angioectasias Despite Treatment with Argon Plasma Coagulation Requiring Thalidomide Treatment in a Patient with Cirrhosis: A Rare Case Report.

Gastrointestinal (GI) angioectasia is an important cause of acute GI bleed, particularly in the elderly; however, GI angioectasia is an uncommon cause of upper GI bleeding related to cirrhosis. With the increasing incidence of liver cirrhosis and recent improvements in the treatment of advanced cirrhosis, this condition may become more common and should be considered a differential diagnosis in patients with cirrhosis who present with occult or overt GI blood loss. We present the case of a 66-year-old man with liver cirrhosis admitted with acute upper GI bleeding that was found to have antral and duodenal angioectasia during esophagogastroduodenoscopy (EDG). Argon plasma coagulation (APC), which is considered the gold standard treatment for angioectasias was performed for hemostasis but was not successful in our case. The next option was a combination of estrogen and progesterone, which was refused by the patient. Finally, thalidomide was administered and the patient responded to the medication, which was evident by the resolution of angioectasia during a repeat endoscopy done six months after treatment.

Twenty-Eight-Day-Long Delirium Tremens.

Refractory alcohol withdrawal delirium is uncommon in day-to-day clinical practice. This case report presents a rare case of delirium tremens of unusually long duration that was complicated by the difficulty in tapering down benzodiazepines despite adding midazolam drip as well as phenobarbitone to the management regimen and excluding other possible diagnoses.

Acquired Thrombotic Thrombocytopenic Purpura in a Patient with Pernicious Anemia.

Introduction. Acquired thrombotic thrombocytopenic purpura (TTP) has been associated with different autoimmune disorders. However, its association with pernicious anemia is rarely reported. Case Report. A 46-year-old male presented with blood in sputum and urine for one day. The vitals were stable. The physical examination was significant for icterus. Lab tests' results revealed leukocytosis, macrocytic anemia, severe thrombocytopenia, renal dysfunction, and unconjugated hyperbilirubinemia. He had an elevated LDH, low haptoglobin levels with many schistocytes, nucleated RBCs, and reticulocytes on peripheral smear. Low ADAMTS13 activity (<10%) with elevated ADAMTS13 antibody clinched the diagnosis of severe acquired TTP, and plasmapheresis was started. There was an initial improvement in his hematological markers, which were however not sustained on discontinuation of plasmapheresis. For his refractory TTP, he was resumed on daily plasmapheresis and Rituximab was started. Furthermore, the initial serum Vitamin B12 and reticulocyte index were low in the presence of anti-intrinsic factor antibody. So with the concomitant diagnosis of pernicious anemia, Vitamin B12 was supplemented. The rest of the immunological workups were negative. Subsequently, his symptoms resolved and his hematological parameters improved. Discussion. While pernicious anemia can masquerade as TTP, an actual association between the two can also occur and needs further evaluation and characterization.
