A Woman with Bilateral Pheochromocytoma and Tuberous Sclerosis Complex.

Background/Objective: Pheochromocytoma and paraganglioma (PPGL) are rare neuroendocrine tumors. Here, we report an unusual case of synchronous PPGL in an asymptomatic patient with tuberous sclerosis complex (TSC). Case Report: A 49-year-old woman with a history of TSC and end-stage renal disease was referred for evaluation of bilateral adrenal and retroperitoneal masses. She denied chest pain, palpitations, headaches, or previous hypertensive crisis. The laboratory test results showed a plasma normetanephrine level of 20.20 nmol/L (normal range, 0.00-0.89 nmol/L) and plasma chromogranin A level Chromogranin A (CgA) levels of 1518 ng/mL (normal range, 0-103 ng/mL). The plasma metanephrine level was normal. After α-blockade, the patient underwent bilateral adrenalectomy and retroperitoneal mass excision. Pathology confirmed these lesions to be pheochromocytoma and composite paraganglioma/ganglioneuroma, respectively. Her plasma normetanephrine level normalized postoperatively, and the chromogranin A levels improved to 431 ng/mL. Discussion: Routine imaging has increased the incidental diagnosis of PPGL. Diagnostic workup includes measurement of the urinary and/or plasma metanephrine and catecholamine levels followed by tumor localization. Patients with young age, syndromic lesions, bilateral PPGL, or unilateral disease with a positive family history should have genetic testing. Definitive treatment is surgical after α-blockade. Conclusion: This case highlights a rare presentation of bilateral PPGL in a patient with TSC.

The Evolution of Diabetes Technology - Options Toward Personalized Care.

OBJECTIVE: Advances in diabetes technology, especially in the last few decades, have transformed our ability to deliver care to persons with diabetes (PWDs). Developments in glucose monitoring, especially continuous glucose monitoring (CGM) systems, have revolutionized diabetes care and empowered our patients to manage their disease. CGM has also played an integral role in advancing automated insulin delivery systems. OBSERVATIONS: Currently available and upcoming advanced hybrid closed-loop systems aim to decrease patient involvement and are approaching the functionality of a fully automated artificial pancreas. Other advances, such as smart insulin pens and daily patch pumps, offer more options for patients and require less complicated and costly technology. Evidence to support the role of diabetes technology is growing, and PWD and clinicians must choose the right type of technology with a personalized strategy to manage diabetes effectively. CONCLUSION AND RELEVANCE: Here, we review currently available diabetes technologies, summarize their individual features, and highlight key patient factors to consider when creating a personalized treatment plan. We also address current challenges and barriers to the adoption of diabetes technologies.

Persistent or Recurrent Disease in Thyroid Cancer Survivors Who Have Elevated Serum Antithyroglobulin Antibodies.

OBJECTIVE: Detection of residual differentiated thyroid cancer is important but difficult. A variety of imaging modalities and biochemical markers has been used with moderately good success. We hypothesized that elevated perioperative serum antithyroglobulin antibody (TgAb) levels would also be a predictive marker for persistent or recurrent thyroid cancer. METHODS: We performed a retrospective analysis of 277 differentiated thyroid cancer survivors divided into 2 groups: (1) those with low or normal serum TgAb (TgAb-) and (2) those with elevated serum TgAb (TgAb+). All patients were seen at one major academic medical center. Patients were followed for a median of 7.54 years. RESULTS: Patients in the TgAb+ group were more likely to have positive lymph nodes at initial surgery, to be assigned to a higher American Joint Committee on Cancer stage, and to have significantly higher incidence of persistent/recurrent disease. The higher incidence of persistent/recurrent cancer was significant under univariable and multivariable (including TgAb status, age, and sex) Cox proportional hazards model analysis. CONCLUSION: We conclude that individuals with elevated serum TgAb at the outset should be followed with a higher index of suspicion for persistent/recurrent thyroid cancer.

Role of body mass index in outcomes of patients hospitalized with COVID-19 illness.

Background: Since the start of coronavirus disease 2019 (COVID-19) pandemic, several studies have linked obesity with severity of illness as well as mortality in patients with COVID-19. Outcomes of patients with overweight or obesity, who develop critical illness, have been studied extensively over the past decade where the studies have shown conflicting results. In this study, we aimed to assess the association between the body mass index (BMI) classes and outcomes among hospitalized patients with COVID-19. Methods: This was a retrospective chart review of all adults admitted to our hospital with COVID-19 illness between 1 March 2020 and 30 June 2020. Patients were divided into four groups based on their BMI range as follows: patients with underweight (BMI < 18.5 kg/m2), patients with normal weight (BMI 18.5-24.9 kg/m2), patients with overweight (BMI 25-29.9 kg/m2), and patients with obesity (BMI ≥ 30 kg/m2). Results: 1274 patients were admitted during the study period. There were 24 (1.9%) patients with underweight, 268 (21%) patients with normal weight, 445 (34.9%) patients with overweight, and 537 (42.2%) patients with obesity. Patients with obesity were younger (p < 0.001) and there were more females among patients with underweight and patients with obesity (54% and 48% respectively, p < 0.001). There were no differences in subgroup with regards to presence of hypertension, diabetes mellitus, coronary artery disease, congestive heart failure, and dyslipidemia. In a multivariate logistic regression model, patients with overweight and patients with obesity had higher odds of requiring mechanical ventilation. BMI class was not associated with difference in survival time in a multivariate analysis. Conclusions: In our large single-center study of hospitalized patients with COVID-19, patients with overweight and obesity had higher need for mechanical ventilation but had similar mortality when compared to patients with normal weight and underweight.

Management of Hyperglycemia in the Noncritical Care Setting: A Real-World Case-Based Approach With Alternative Insulin- and Noninsulin-Based Strategies.

Insulin remains the mainstay of treatment for inpatient hyperglycemia in the United States and Canada. However, some other countries commonly use noninsulin agents such as metformin and sulfonylureas, and several trials have demonstrated the efficacy and safety of incretin-based agents in patients with type 2 diabetes who are admitted to noncritical care medicine and surgery services. There is a high degree of interest in alternative glucose-lowering strategies to achieve favorable glycemic outcomes with lower risks of hypoglycemia. In this case series, we highlight the challenges of inpatient glycemic management and the need for alternatives to the traditional basal-bolus insulin regimen. Additional investigation will be imperative to validate the safety and efficacy of appropriate insulin and noninsulin treatments and to further develop guidelines that are applicable in real-world hospital settings.

Implementation and outcomes of monoclonal antibody infusion for COVID-19 in an inner-city safety net hospital: A South-Bronx experience.

BACKGROUND: Monoclonal antibody therapy (MAT) is recommended in mild to moderate Coronavirus disease 2019 (COVID-19) patients who are at risk of progressing to severe disease. Due to limited data on its outcomes and the logistic challenges in administering the drug, MAT has not been widely used in the United States (US) despite of emergency use authorization (EUA) approval by the Food and Drug Administration (FDA). AIM: We aim to study the outcomes of MAT in patients predominantly from ethnic minority groups and the challenges we experienced in implementing the infusion therapy protocol in an inner-city safety-net-hospital in the South Bronx. METHODS AND RESULTS: We conducted a retrospective observational study of 49 patients who were offered MAT as per EUA protocol of FDA. Patient who met the criteria for MAT and received therapy were included in treatment group (n = 38) and the remaining (n = 11) who declined treatment were included in the control group. A majority of patients (76%) in the study group reported symptomatic improvement, the day after infusion. There was statistically significant reduction in COVID-19 related hospitalizations (7.8 vs 54.5%, P = < 0.001) mortality (0 vs 18.1%, P value = 0.008) in the treatment group. CONCLUSION: MAT reduced both hospitalization and mortality in this predominantly Hispanic patient population with mild to moderate COVID-19 with high risk factors for disease progression.

Use of Monoclonal Antibodies Therapy for Treatment of Mild to Moderate COVID-19 in 4 Patients with Rheumatologic Disorders.

BACKGROUND The use of monoclonal antibodies therapy (MAT) in early mild to moderate Coronavirus disease 2019 (COVID-19) has gained importance in recent times. However, there is limited information on the safety and efficacy of MAT in treating COVID-19 in patients with underlying rheumatologic diseases. Patients with rheumatologic diseases are usually on long-term corticosteroids and immunosuppressive therapy, which increases their risk for progressing to more severe forms of COVID-19. We report a case series of 4 patients with rheumatologic diseases who were treated with MAT for COVID-19. MATERIAL AND METHODS A retrospective observational study was conducted in our institution on patients with underlying rheumatological disorders who received MAT as per the EUA protocol of the FDA. RESULTS Two of the 4 patients were on immunosuppresive therapy at the time of receiving MAT. They recovered from COVID-19 without any adverse outcomes. No flare of underlying rheumatologic disease was noted. CONCLUSIONS MAT was observed to be a safe and effective therapy in 4 patients with rheumatological illnesses and COVID-19 treated at our hospital.

Encephalitis Due to Co-Infection with Cytomegalovirus and Herpes Simplex Virus Type 2 in a Patient with Acquired Immunodeficiency Syndrome.

BACKGROUND Opportunistic infections are commonly seen in immunocompromised patients. Here, we present an interesting case of a patient with poorly controlled human immunodeficiency virus (HIV) infection who presented with multiple opportunistic infections. CASE REPORT A 44-year-old woman with medical history of HIV infection (CD4 <20 cells/µl, viral load 172 996 copies/ml), presented with symptoms of headache for 2 days and changes in mentation. She was recently treated for pulmonary mycobacterium avium complex infection. Her physical examination revealed normal breath sounds and her abdominal examination was unremarkable. She did not have any focal neurological deficits, nuchal rigidity, or papilledema on examination. Computed tomography (CT) head was negative for any acute lesions. She was empirically started on vancomycin and piperacillin-tazobactam. Due to persistent symptoms, a lumbar puncture was performed, which revealed elevated total proteins in CSF, and a viral polymerase chain reaction test was positive for herpes simplex virus type 2 (HSV-2) and cytomegalovirus (CMV). Magnetic resonance imaging of the brain showed mild enhancement of the ventricular lining. She was treated with acyclovir, which was later changed to ganciclovir, with resulting clinical improvement. The patient had clinical improvement and was discharged home. CONCLUSIONS Multiple opportunistic co-infections should be considered in patients with poorly controlled HIV infection.

Potential predictors of outcomes among hospitalized COVID-19 patients treated with convalescent plasma: a single-center study.

Background: The coronavirus disease 2019 pandemic is a major international public health crisis, which has led to over 3 million deaths as of April 2021. Several therapeutics have been tried for this deadly illness including antivirals, immunosuppressive agents and convalescent plasma (CP). In this study, we present our inner-city safety net hospital experience with CP therapy. Methods: This was a retrospective chart review of hospitalized patients with confirmed COVID-19 who were treated with CP. Results: A total of 60 patients received CP during the study period. The mean age for patients in this study was 58.95 years. The most common presenting symptoms were shortness of breath (85%) and cough (73%). Hypertension (65%) and diabetes mellitus (55%) were the most common comorbidities in our patients. In our multivariate regression analysis, male sex, nausea and loss of appetite at presentation were associated with improvement in oxygenation after CP. Total survival time, history of obstructive airway disease, home use of angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers were associated with decreased survival, whereas Hispanic ethnicity showed a trend towards lower survival after CP therapy. Conclusions: Our study highlights several important characteristics of inner-city safety net hospital patient population who might benefit from CP therapy.

Impact of Prediabetes and Type-2 Diabetes on Outcomes in Patients with COVID-19.

INTRODUCTION: The true impact of prediabetes and type-2 diabetes in patients with COVID-19 remains unknown, with studies thus far providing conflicting evidence. METHODS: This is a single-center retrospective observational study involving 843 hospitalized patients with SARS-CoV-2 infection. Primary outcomes, mortality, and mechanical ventilation use were compared among the three groups: control, prediabetes, and type-2 diabetes. Binomial regression analysis was used to determine predictors of mortality and mechanical ventilation requirement. RESULTS: Age was a significant predictor of mortality. On stratifying our patients based on their age, older patients aged 55 years and above had no difference in mortality or mechanical ventilation requirement among the three groups of control, prediabetes, and type-2 diabetes. However, among the younger population aged less than 55 years, patients with type-2 diabetes had significantly higher mortality as compared with patients in control and prediabetes groups (27% vs 12.5% vs 9%, p 0.025). Additionally, newly diagnosed type-2 diabetes patients demonstrated lower mortality rate in comparison to previously known type-2 diabetes patients (18% vs 40%, p 0.005). Outcomes in the prediabetes group were similar to that in the control group. Admission hyperglycemia was associated with higher mortality regardless of diabetes status. CONCLUSION: In older patients aged 55 years and above, status of type-2 diabetes does not influence their mortality. However, in younger patients aged less than 55 years, the presence of type-2 diabetes is an important driver of mortality. Newly diagnosed type-2 diabetes, in comparison with previously diagnosed type-2 diabetes, may have better survival. Presence of prediabetes did not affect outcomes in patients with COVID-19 infection.

BNT162b2 mRNA Vaccine Interference with Co-Administration of Tdap Vaccine.

BACKGROUND It is unknown if the efficacy of the coronavirus disease-19 (COVID-19) vaccine is affected by the co-administration of other vaccines. The Centers for Disease Control and Prevention (CDC) has shifted their recommendations recently, allowing for the co-administration of the currently available COVID-19 vaccines with other vaccines. This is based on the experience with non-COVID-19 vaccines, where the immunogenicity and adverse event profiles were generally similar when vaccines are administered simultaneously or alone. CASE REPORT We present a case of a 29-year-old Asian woman who received the first dose of BNT162b2 mRNA vaccine and the tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine at around the same time. BNT162b2 mRNA vaccine and Tdap vaccine were administered into the deltoid region of the left arm and right arm, respectively. We then monitored for immunogenicity. We observed a delay in the development of SARS-CoV-2 Spike (S1) protein antibodies at around 8 weeks after the second dose. CONCLUSIONS Unless warranted, it is important to adhere to current CDC recommendations with regards to the co-administration of vaccines. Although the administration of Tdap with COVID-19 vaccine in our case caused delay in immunogenicity, it did not negate the ability of the BNT162B2 mRNA vaccine to elicit an adequate immune response. The reason for delay in immune response with co-administration of COVID-19 vaccines with other vaccines is unknown and further studies are needed.

COVID-19 Vaccine Failure in a Patient with Multiple Sclerosis on Ocrelizumab.

Vaccines will play a key role in ending the COVID-19 pandemic. Vaccination against infections remains an important part of the management of patients with multiple sclerosis. However, there are limited data about the safety and efficacy of the currently available COVID-19 mRNA vaccines in patients with multiple sclerosis receiving concurrent immunosuppressive therapies. Patients on B cell depleting therapy such as ocrelizumab have an attenuated vaccine response. We report the first case of COVID-19 vaccine failure in a patient with relapsing-remitting multiple sclerosis on B cell depleting therapy, ocrelizumab. We offer suggestions to improve vaccine efficacy in these patients.

Association of smoking status with outcomes in hospitalised patients with COVID-19.

INTRODUCTION: Smoking causes inflammation of the lung epithelium by releasing cytokines and impairing mucociliary clearance. Some studies have linked smoking with severity of illness of COVID-19 whereas others have found no such association. METHODS: This was a retrospective analysis of all adults hospitalised with COVID-19 from 9 March to 18 May 2020. RESULTS: 1173 patients met the study criteria. 837 patients never smoked whereas 336 patients were either current smokers or past smoker and were grouped together in smokers group. Patients in smokers group were more likely to be male and had higher incidence of underlying chronic obstructive pulmonary disease (19% vs 6%, p<0.001), HIV infection (11% vs 5%,p<0.001), cancer (11% vs 6%, p=0.005), congestive heart failure (15% vs 8%, p<0.001), coronary artery disease (15% vs 9%, p=0.3), chronic kidney disease (11% vs 8%, p=0.037) and end-stage renal disease (10% vs 6%, p=0.009) compared with non-smokers. Outcome analysis showed that smokers were more likely to develop critical illness requiring mechanical ventilation (47% vs 37% p=0.005). Univariate Cox model for survival analysis by smoking status showed that among smokers only current smokers had higher risk of death compared with never smokers (HR 1.61, 95% CI 1.22 to 2.12, p<0.001). In the multivariate approach, Cox model for the survival, female sex, young age, low serum lactate dehydrogenase and systemic steroid use were associated with overall improved survival. CONCLUSION: In our large single-centre retrospective database of patients hospitalised with COVID-19, smoking was associated with development of critical illness and higher likelihood of death.

The Association of Renin-Angiotensin-Aldosterone System Inhibitors With Outcomes Among a Predominantly Ethnic Minority Patient Population Hospitalized With COVID-19: The Bronx Experience.

Background and objective Angiotensin-converting enzyme inhibitors (ACE) and angiotensin II receptor blockers (ARB) are commonly used for the treatment of patients with heart disease, hypertension (HTN), and diabetes mellitus (DM). In the aftermath of the emergence of the coronavirus disease 2019 (COVID-19) pandemic, initial data raised concerns that ACE/ARB use can increase the expression of ACE2 receptors, leading to the worsening of COVID-19. However, recent studies have suggested that their use might be safe in a select subgroup of patients. We conducted a single-center retrospective study to evaluate the association of in-patient use of ACE/ARB with outcomes among a predominantly ethnic minority patient population of the inner New York City (NYC). Methods This was a retrospective analysis of all hospital admissions with COVID-19 from March 1, 2020, to March 31, 2020. Results Of the 469 patients included in the study, 91 patients (19.4%) used ACE/ARB therapy during their hospital stay and were labeled as ACE/ARB group. Patients in the ACE/ARB therapy group were older and had a higher incidence of HTN, coronary artery disease (CAD), congestive heart failure, DM, asthma, and chronic obstructive pulmonary disease. Admission D-dimer, lactate dehydrogenase (LDH), and C-reactive protein (CRP) levels were similar between the two groups, but absolute lymphocyte count (ALC) was lower in the non-ACE/ARB group (0.971 k/ul vs. 1.135 k/ul, p=0.0144). The incidence of hyperkalemia and the rise in creatinine were similar between the two groups. Univariate analysis by treatment group using the log-rank test produced significant results (p=0.0062), indicating a higher survival rate for the ACE/ARB group. Conclusion The use of ACE/ARB appears to be safe in all patients in whom their use is medically indicated.

A Rare Case of Cerebellar Glioblastoma Mimicking Acute Stroke in an Elderly Patient.

BACKGROUND Glioblastoma (GB) is a common brain tumor that usually presents in the cerebral hemisphere. Very rarely, these tumors can present in the cerebellum. The tumor tends to have a diffuse infiltrative growth that follows the white-matter pathway. Cerebellar GB is often difficult to diagnose on imaging and a biopsy is often needed for diagnosis. Here, we present the case of an elderly woman who presented with symptoms suggestive of acute stroke. CASE REPORT An 82-year-old woman presented for intermittent dizziness that started 2 weeks prior to the presentation and had been progressively worsening. She had a prior history of stroke and was noted to have decreased motor strength and sensation to touch on the left side. A cranial nerve examination was normal, as was finger-nose testing. Magnetic resonance imaging (MRI) of the brain with and without contrast showed an enhancing lesion in the left posterior cerebellum producing a mass effect in the left lateral ventricle. The differential diagnosis included cerebellitis with abscess, neoplastic process with necrosis, and, less likely, a sub-acute infarction A suboccipital craniotomy with cerebellar biopsy-diagnosed cerebellar GB. CONCLUSIONS We report the unique presentation of cerebellar GB in an elderly woman who presented with left-sided weakness, elevated blood pressure, dizziness, vasogenic edema in the left cerebellum, and a mass effect on the fourth ventricle, mimicking acute stroke.

Acute Cytomegalovirus (CMV) Hepatitis in an Immunocompetent Adult.

BACKGROUND Cytomegalovirus (CMV) is a member of Herpesviridae family with its name derived from the fact that it causes enlargement of the infected cell resulting in the characteristic inclusion bodies seen on microscopy. CMV virus has an incubation period of about 4 to 6 weeks. Symptoms of CMV infection vary and depend on factors including the age and immune status of the patient. It usually presents as asymptomatic infection in immunocompetent individuals whereas severe disease is usually seen in immunocompromised patients. Here we present a case of an immunocompetent patient who presented with acute CMV hepatitis. CASE REPORT A 35-year-old male with no significant prior medical history who presented to the Emergency Department with a 2-week history of low-grade fever. Acute CMV infection was diagnosed by positive CMV antibody and polymerase chain reaction (PCR) testing. The patient was treated with valganciclovir that resulted in rapid improvement in clinical status as well as normalization of the liver enzymes. CONCLUSIONS This article presents a rare case of immunocompetent young male with acute CMV hepatitis who responded favorably to antiviral therapy.

Case report: An unusual presentation of acute promyelocytic leukemia in a middle aged female mimicking dengue infection.

RATIONALE: Acute promyelocytic leukemia (APL) is an uncommon subtype of acute myeloid leukemia (AML). M3v phenotype is a less common presentation of APL and these patients usually present with leukocytosis and abnormal promyelocytes that are characterized by sparse granulation and are less likely to have faggot cells with multiple Auer rods. Distinguishing M3v phenotype from acute febrile illness can be challenging as the diagnosis relies on examination of peripheral smear. PATIENT CONCERNS: Fifty-seven-year-old female who presented after recent trip to Dominican Republic for high grade fever and gum bleeding. She was exposed to patients with Dengue fever during her stay. At presentation, patient had leukocytosis, thrombocytopenia, and urinalysis showing bacteria and white cell. She was started on treatment for urinary tract infection. Patient remained febrile and thrombocytopenia worsened. On day 2, flow cytometry of the peripheral smear showed 43% medium sized blasts. Fluorescence in situ hybridization was positive for promyelocytic leukemia/retinoic acid receptor alpha. DIAGNOSES: The patient was diagnosed with APL. INTERVENTIONS: Patient was started on treatment with all-trans retinoic acid and arsenic trioxide along with supportive care OUTCOMES:: Patient had a favorable clinical response and her symptoms subsided. LESSONS: Flow cytometry of the peripheral smear is key to diagnosis of suspected APL. One must maintain high suspicion for this life-threatening condition as early diagnosis saves lives.
