H. pylori is the most common infection in the world and is associated with gastrointestinal and extra-gastrointestinal manifestations, including peptic ulcer disease, gastrointestinal bleeding, and lymphoproliferative disorders. Despite being discovered less than half a century ago, antibiotic resistance, exacerbated by medication non-adherence and inefficacy of proton pump inhibitors, has grown substantially, explaining the rising incidence of refractory H. pylori infection. In this review, we discuss risk factors, treatment options, surveillance and follow-up, as well as emerging therapies for refractory H. pylori.

Abstract Clostridioides difficile infection (CDI) is an issue of great concern due to its rising incidence, recurrence, morbidity and impact on healthcare spending. Treatment guidelines have changed in the last few years, and new therapies are being considered. This is a practical review for the primary care practitioner of the latest guidelines for CDI diagnosis, treatment, and emerging therapies.

Abstract Helicobacter pylori is the most prevalent bacteria infecting humans resulting in a variety of gastrointestinal and extra gastrointestinal complications. Although most of the infected adults are asymptomatic, the prevalence varies in different parts of the world it is higher in Eastern and Southern Europe. Eradication of Helicobacter pylori is necessary to prevent precancerous conditions like gastric atrophy, gastric intestinal metaplasia and gastric dysplasia. This comprehensive review addresses briefly on: whom and how to test and treat including recommended first line therapies, salvage therapies, testing for eradication and strategy to be used in primary care clinics.

Abstract The COVID-19 pandemic continues to overwhelm global healthcare systems. While the disease primarily causes pulmonary complications, reports of central nervous system (CNS) involvement have recently emerged ranging from encephalopathy to stroke. This raises a practical dilemma for clinicians as to when to pursue neuroimaging and lumbar tap with cerebrospinal fluid (CSF) analysis in COVID-19 patients with neurological symptoms. We present a case of an encephalopathic patient infected with SARS-CoV-2 with no pulmonary symptoms. We propose a three-tier risk stratification for CNS COVID-19 aiming to help clinicians to decide which patients should undergo CSF analysis. The neurological examination remains an integral component of screening and evaluating patients for COVID-19 considering the range of emerging CNS complications.

Introduction: Improving flu vaccination rates in the general population is an important and effective strategy toward reducing morbidity, mortality, and the cost of seasonal influenza. In order to optimize immunization strategies, factors associated with decreased vaccination rates need to be explored. The literature suggests that there is a gender difference in the rate of influenza vaccination but is limited to population-based survey studies and also is inconsistent as to which gender has a higher rate of vaccination. The purpose of this study was to evaluate for a gender-based difference in the rate of influenza vaccination among patients who presented for an annual physical examination during the 2018 to 2019 influenza season. Methods: In this multi-site, retrospective chart review, a total of 1193 patients (608 female and 585 male) who underwent an annual physical examination in April of 2019 were included. Baseline medical information was collected, as well as demographic characteristics and influenza vaccination status. The proportion of patients who underwent influenza vaccination was compared between males and females using multivariable logistic regression models; odds ratios (ORs) were estimated. Results: The likelihood of influenza vaccination was significantly higher in females (62.8%) compared to males (53.2%) in both unadjusted analysis (OR = 1.49, P < .001) and in multivariable analysis adjusting for the potential confounding influences of clinic location, BMI, insurance type, and occupation (OR = 1.42, P = .005). Interestingly, a higher influenza vaccination rate for females compared to males was observed in patients age<60 years (OR = 1.70, P = .025) and between ages 60 and 75 (OR = 1.66, P = .009), but not for patients older than 75 years (OR = 1.12, P = .66). Conclusion: Our findings indicate that the rate of influenza vaccination is higher for females than for males who presented for an annual preventive physical exam and who are younger than 75 years old.

Abstract Patients with chronic liver disease have associated comorbidities that require treatment, including cardiovascular disease, arrhythmias, cerebrovascular accidents and pain. These medications may affect the liver disease. Due to the complexity of medical problems in patients with chronic liver disease, treating clinicians benefit from targeted guidance for their care.

Abstract Pharmacogenomics describes the link between the genetic code and variations in drug response or adverse effects. It is rapidly gaining in both interest and accessibility. The knowledge of the gene-drug pairing for a wide range of medications will allow the clinician to select drugs with the best efficacy, appropriate dose and lowest likelihood of serious side effects. In order to apply this knowledge, practitioners need to be familiar with the basic principles of pharmacodynamics and pharmacokinetics and how these relate to drug response. Once these are understood, so can be the genetic variations that lead to different phenotypes. Our review explains these concepts and uses examples of commonly prescribed medications and their gene pairings. At the present time, the Food and Drug Administration (FDA) guidelines remain sparse in regards to pharmacogenomic testing but, despite this, direct-to-consumer testing is widely available. In this context, we detail how to interpret a pharmacogenomic report, we review the indications for testing, as well as its limitations. This information is a step ahead towards invidualized medicine, in the hope that tailoring medications and doses to an individual’s genetic make-up will predict a safe and effective response.

Abstract Hypokalemic periodic paralysis (HOKPP) is a rare neuromuscular disorder caused by altered transport of cellular potassium that leads to significant muscle weakness of the extremities. Paralytic attacks are induced by a drop in the serum potassium level and they have been associated with specific triggers. This case describes a 21-year-old male who has had recurrent presentations of acute paralytic attacks following vigorous physical activity. At presentation, this patient exhibited flaccid paralysis of all skeletal muscles below the neck, but was alert and oriented with stable vital signs. The patient was found to have a potassium level of 2.1 mmol/L and an EKG demonstrating U waves (characteristic of hypokalemia). The patient was treated with potassium supplementation with resolution of symptoms. The mainstay of prevention of long term permanent muscle weakness is avoidance of triggers that can lead to hypokalemia. Through education on disease process and lifestyle modifications, we were able to end the cycle of recurrent hospital readmissions and the subsequent financial burden this generated for the patient and his family.

Since their introduction for melanoma treatment, the use of immune checkpoint inhibitors (ICIs) has rapidly expanded. Though their impact on survival is irrefutable, these medications have been associated with autoimmune‐like adverse events related to their ability to induce the immune system. One of the most commonly affected organ systems is the gastrointestinal (GI) tract, in which manifestations range from mild diarrhea to severe colitis with intestinal perforation. Because of the increased use of ICIs, hospitalists are caring for an increasing number of patients experiencing their adverse events. We present a case‐oriented review of the GI adverse events associated with the use of ICIs to familiarize the hospitalist with their mechanism of action and potential complications and to emphasize the importance of early diagnosis and treatment to decrease morbidity and mortality.
