ABSTRACT
Case Report: Over 90% of cases of cryptococcal meningoencephalitis present in immunocompromised patients, with the majority of those being in patients with AIDS. However, this infection can also occur in patients with other immunocompromised states, such as steroid use, malignancy, rheumatologic diseases, and use of immunosuppressive medications. Delay in diagnosis can often lead to rapid neurological deterioration and mortality. Case: A young, otherwise immunocompetent patient, with a history of Chiari I malformation and recent COVID- 19 infection presented with syncope following two weeks of headaches, generalized body aches and weakness after COVID-19 diagnosis. Physical exam demonstrated an isolated CN VI palsy. Head imaging revealed new right caudate infarcts, and a cerebellar tonsillar descent compatible with history of Chiari I malformation. Initial lumbar puncture (LP) was deferred due to congenital brain herniation. Over the next few days, the patient continued to show increasing neurological deficits such as truncal ataxia and increased mood instability. The patient was transferred to the Intensive Care Unit, and LP was obtained under special neuro-critical care direction. Due to increased opening pressures and yeast on gram stain, cryptococcus was suspected and later confirmed. Although anti-fungal therapy was initiated, the patient continued to deteriorate, leading to cardiac arrest, intubation, and placement of lumbar drain. The patient unfortunately did not demonstrate neurologic recovery following arrest and progressed to brain death. Discussion(s): While cryptococcal meningoencephalitis is overwhelmingly a disease of immunocompromised patients, it can occur in immunocompetent hosts, and delay in diagnosis and treatment can lead to adverse and fatal outcomes. This patient had no known underlying conditions besides a recent mild COVID-19 infection and underlying Chiari I malformation, neither of which are known to be associated with cryptococcal meningoencephalitis. These factors may however have played a role in his disease and progression. Copyright © 2023 Southern Society for Clinical Investigation.
ABSTRACT
Case Report: A 25-year-old woman with history of Diamond-Blackfan anemia (DBA) presented with a 3- week history of weakness and fatigue. The patient was in her usual state of health until 3 weeks prior when she was diagnosed with COVID-19, at which time she experienced cough, congestion, weakness, and fatigue. She reported that the cough and congestion improved after a few days, but the fatigue and weakness progressively worsened. Admission labs were notable for a hemoglobin of 5.5 g/dL with a MCV of 119.3 fL. She received 2 units of packed RBCs with improvement in hemoglobin to 8.9 g/dL. The patient was diagnosed with DBA at birth via bone marrow biopsy and had been stable on chronic prednisone with a baseline hemoglobin around 8 g/dL. Prior to this admission, she has only required one transfusion at 3 months old. Her outpatient management involved close monitoring of her hemoglobin and increasing/decreasing prednisone based on her trending hemoglobin. She had been stable on 15 mg/day of prednisone for the past few years. Her hematologist was consulted, and the decision was made to increase her dose of prednisone to 20 mg/day resulting in resolution of symptoms and stabilization of her hemoglobin level. Discussion(s): We present a rare case of DBA with worsening anemia in the setting of a recent COVID-19 infection. The literature regarding the risk and complications of COVID-19 in these patients is severely limited, with no current data on disease management, outcomes, or predictors of morbidity. DBA is a rare, congenital erythroid red cell aplasia that typically presents in infancy with an estimated incidence of 5 cases per 1 million births. DBA is characterized by progressive macrocytic anemia, congenital malformations, and increased risk of endocrine dysfunction and malignancies. Glucocorticoids are the first-line therapy for DBA, although the exact mechanism of how they stimulate erythropoiesis in DBA remains unknown. In terms of patient prognosis, approximately 40% are steroid-dependent, 40% are transfusiondependent, and 20% go into remission by age 25 years.
