Hyperlipidemia in the Setting of Primary Biliary Cholangitis: A Case Report and Review of Management Strategies.

Primary biliary cholangitis (PBC) is a chronic and progressive cholestatic autoimmune liver disease. Its characteristic is the destruction of intrahepatic bile ducts with portal inflammation and scarring. In the setting of cholestasis, there is a reduction in bile acid production and, consequently, decreased intestinal absorption of cholesterol. The result is the endogenous synthesis of cholesterol in the liver and the secretion of very low-density lipoprotein. Mixed hyperlipidemia can be challenging to manage, and the association with increased cardiovascular events remains unclear.

Radical treatment for blastomycosis following unsuccessful liposomal amphotericin.

Pulmonary blastomycosis is a respiratory disease that is caused by the fungus Blastomyces spp, which is acquired through inhalation of the fungal spores. Blastomycosis is relatively uncommon, with yearly incidence rate of 1-2 cases per 100 000 people. Blastomycosis is a disease that is endemic to the midwest and southern regions of the USA, most commonly affecting immunocompromised patients. About 50% of patients are asymptomatic, but for those who progress to acute respiratory distress syndrome (ARDS) mortality can be as high as 80%. Patients with severe blastomycosis are initially treated with intravenous amphotericin B, followed by long-term itraconazole maintenance therapy. In this Grand Round, we present the case of an immunocompetent 35-year-old man diagnosed with chronic pulmonary blastomycosis who had a poor response to 10 days of intravenous liposomal amphotericin B (L-AmB). He was endotracheally intubated and eventually cannulated for extracorporeal membrane oxygenation (ECMO), due to worsening respiratory function. L-AmB was replaced with a continuous infusion of intravenous amphotericin B deoxycholate (AmB-d). He improved significantly and was decannulated from ECMO on day 9 of AmBd continuous infusion and extubated on day 12 Although L-AmB is considered first-line treatment for blastomycosis, mortality remains high for patients with ARDS associated with blastomycosis. This case highlights the importance of considering AmB-d continuous infusions for patients with severe blastomycosis who might have poor clinical responses to L-AmB.

A Rare Case of Good Outcome of Hodgkin Lymphoma in a Patient with HIV on Antiretroviral Therapy (ART).

BACKGROUND Recent reports have shown an increased incidence of Hodgkin lymphoma (HL) in patients treated with antiretroviral therapy (ART) for human immunodeficiency virus (HIV) infection. This report is of a case of nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) with a good outcome in a 58-year-old Nigerian HIV-positive man who was being treated with ART. CASE REPORT A 58-year-old HIV-positive man presented to a clinic for evaluation of a left axillary mass. He was diagnosed with HIV in 2005, which was well-controlled by ART. He reported intermittent swelling in the left axillary region for several years. Results of a physical examination were significant for mild tender left anterior axillary lymphadenopathy. He had a computed tomography (CT) scan of the chest and neck, which showed left axillary adenopathy, with the largest measuring 3.5×2.0 cm. A staging positron emission tomography-computed tomography (PET/CT) showed focal uptake in 2 left axillary lymph nodes with no other sites involved. He underwent excision of the left axillary lymph node. Histopathology was consistent with nodular lymphocyte-predominant-type Hodgkin's lymphoma (NLHPL). He underwent radiation therapy with a total dose of 3600 centigray (cGy) according to National Comprehensive Cancer Network (NCCN) guidelines. The 5-month follow-up PET/CT scan showed no evidence of malignancy. CONCLUSIONS We present a case of HIV-associated NLHPL that had an indolent course and a good treatment outcome. This case highlights the importance of regular physical examination in HIV patients while on treatment with ART and accurate diagnosis of the cause of lymphadenopathy to prevent extra-nodal spread in cases of lymphoma.

A Rare Case of Epstein-Barr Virus: Infectious Mononucleosis Complicated by Guillain-Barré Syndrome.

Infectious mononucleosis (IM) is an acute disease caused by Epstein-Barr virus (EBV) infection affecting adolescents and young adults. Clinically, IM presents with fever, lymphadenopathy, and tonsillar pharyngitis. Guillain-Barré syndrome (GBS) has been reported as a possible rare complication of IM. IM-induced GBS is known but rarely reported in the literature. Here, we describe the case of a 19-year-old male with no significant medical history who was diagnosed with GBS following EBV-associated IM. A 19-year-old Caucasian male presented from a referring facility after complaining of generalized weakness involving the upper and lower extremity for about five days. Symptoms began with a sensation of tingling and numbness in the fingertips and toes that progressed over five days to where he was no longer able to ambulate. Physical examination was significant for oropharyngeal exudates, posterior oropharyngeal erythema, tonsillar hypertrophy, cervical lymphadenopathy, flaccid paralysis with areflexia, and paresthesia. Diagnostic workup was consistent with IM and GBS based on cerebrospinal findings. He was subsequently admitted to the intensive care unit, where he received plasmapheresis and intravenous immunoglobulin with significant improvement. This is a rare case of EBV-associated IM GBS. IM is a self-limiting disease but can lead to GBS as one of the known but rare complications. Neurological events have been reported in approximately 2% of patients. Only a few cases of IM leading to GBS have been reported in the literature. Detailed history and physical examination can help identify patients with IM-induced GBS. Moreover, increased awareness can help physicians easily identify and manage GBS, enabling timely recognition and initiation of prompt supportive care to improve recovery time.

A Case of Multiple Sclerosis Uncovered Following Moderna SARS-CoV-2 Vaccination.

Multiple sclerosis is a demyelinating disorder of the central nervous system characterized by lesions disseminated in time and space. The diagnostic criteria for laboratory-supported definite multiple sclerosis involve two episodes of symptoms, evidence of at least one white matter lesion on MRI, and abnormal oligoclonal bands in cerebrospinal fluid. Patients usually present in their early 20s and on average have up to one flare-up per year. While vaccines play an important role in the prevention of many diseases, they have often been purported as a potential trigger of multiple sclerosis and multiple sclerosis relapses. The medical literature provides reliable information concerning the risk of developing multiple sclerosis and multiple sclerosis relapses following the administration of most vaccines, but not much is known about the novel Moderna severe acute respiratory syndrome coronavirus 2 (SARS­CoV­2) vaccine. We report the case of a 24-year-old male who presented with right-sided facial weakness, dizziness, and dysarthria two days after receiving his first dose of the Moderna coronavirus disease 2019 (COVID-19) vaccine. Imaging studies noted both acute and chronic central nervous system lesions. He met the diagnostic criteria for laboratory-supported definite multiple sclerosis. His acute flare was treated with intravenous corticosteroids and the patient was subsequently started on ocrelizumab. This case serves as an important example of the novel Moderna SARS-CoV-2 vaccine as a potential trigger of multiple sclerosis relapse. In addition, we review the literature for similar occurrences with the other COVID-19 vaccines and provide reliable guidance for COVID-19 vaccination for patients with multiple sclerosis.
