Autoimmune Hepatitis (AIH) is a progressive form of chronic hepatitis, with periods of remissions and exacerbations. Diagnosis includes abnormally high levels of immunoglobulins and multiple autoantibodies. Clinical presentation is variable, with a spectrum extending from asymptomatic cases to fulminant liver failure. Symptoms include abdominal pain, malaise, fatigue, and small joint arthralgia. We present a case of a 36-year-old male with a past medical history of alcohol dependence and acute pancreatitis who was diagnosed with AIH. There is limited data regarding patients with concomitant AIH and pancreatitis. Our patient presented with AIH with secondary acute on chronic pancreatitis, in the absence of additional autoimmune manifestations. The mechanism of AIH remains poorly understood; however, there is an association between the HLA gene and AIH. Genetic studies have shown HLA-DRB1*0301 and HLA-DRB1*0401 as primary and secondary genotypes susceptible to AIH, as well as genetic variants with CARD10 and SH2B3. Products secondary to metabolism of ETOH such as alcohol dehydrogenase, malondialdehyde, and acetaldehyde, can lead to development of autoantibodies. Additional research is indicated to evaluate the relationship between AIH and acute pancreatitis.

Panniculitis is an inflammatory process localized to subcutaneous tissue, with etiologies including infection, malignancy, external insults, enzymatic destructive processes, and inflammatory disorders. The incidence of panniculitis manifesting as necrosis of subcutaneous fat tissue associated with pancreatic diseases is low, which may encompass associated periarthritis with bone necrosis and panniculitis (Pancreatitis, panniculitis and polyarthritis syndrome). Pancreatitis, panniculitis and polyarthritis syndrome is considered to derive from the systemic activity of enzymes within the pancreas, which leads to disturbances within the microcirculatory system, and fat necrosis of medullary bone marrow; however, the exact pathophysiology remains unknown. Here, we present a case of a 53-year-old male with a history of chronic pancreatitis who presented with lower abdominal pain found to have osteolytic pelvic lesions considered to be panniculitis secondary to pancreatitis. Our patient provided an interesting clinical picture given his alcohol use disorder, and lytic lesions which lead the team initially towards a malignant etiology of panniculitis such as myeloma; however, given his negative studies, it was presumed his panniculitis was derived from his chronic pancreatitis. Overall, additional literature is warranted regarding the extensive workup of lytic bone lesions that present in patients who have acute vs chronic pancreatitis.

The carotid sinus-arterial baroreflex is essential in maintaining blood pressure (BP) regulation. Afferent baroreflex failure (ABF) can present with labile changes in BP within seconds and can be secondary to neck surgery or radiation. We present here the first case, to our knowledge, of ABF precipitated by thyroidectomy, in a patient with active COVID-19 pneumonia, causing difficult control of severely labile BP in a critical care unit. Contributing factors included her critical illness state with upregulation of IL-6 leading to pituitary-adrenal axis alteration, her thyroidectomy further exacerbating autonomic dysfunction, as well as downregulation of ACE2 via COVID-19 infection. Management was achieved with a combination of midodrine and clonidine catered to specific BP thresholds. Additional research with a multidisciplinary approach is warranted to fully optimize the treatment of ABF in patients with neck surgery and or inflammatory conditions such as COVID-19.

Cerebral venous sinus thrombosis (CVST) is a rather uncommon disorder. CVST is potentially lethal, therefore early detection and treatment is critical. CVST has been linked to pregnancy and puerperium, while COVID-19 infection has been linked to a hypercoagulable state. CVST can be difficult to detect and treat due to the wide range of neurological manifestations, especially in patients with hypercoagulability. The goal of this study is to conduct a literature review and present a unique case of a pregnant woman with CVST who had left hemiplegia and headache. After 6 months of treatment in the hospital, the patient's hemiplegia was fully resolved. Here, we discuss the treatment of CVST in pregnant women who have a suspected past COVID-19 infection.
