Primary biliary cholangitis (PBC) is a chronic, cholestatic condition associated with symptoms that directly impact the quality of life in those afflicted with the disease. In addition to pruritus and fatigue, patients with PBC may develop metabolic bone disease from reduced bone density, such as osteopenia and osteoporosis. Osteoporosis increases the risk of fractures, as well as morbidity and mortality. The prevalence of osteoporosis in PBC is expected to increase in conjunction with the rising prevalence of PBC as a whole. Timely diagnosis, prevention and management of osteoporosis are crucial in order to optimize the quality of life. There is a paucity of data evaluating the management of osteoporosis in PBC. The optimal timing for diagnosis and monitoring is not yet established and is guided by expert opinion. National guidelines recommend screening for osteoporosis at the time of diagnosis of PBC. Monitoring strategies are based on results of initial screening and individual risk factors for bone disease. Identifying reduced bone density is imperative to institute timely preventive and treatment strategies. However, treatment remains challenging as efficacious therapies are currently lacking. The data on treatment of osteoporosis in PBC are mostly extrapolated from postmenopausal osteoporosis literature. However, this data has not directly translated to useful treatment strategies for PBC-related osteoporosis, partly because of the different pathophysiological mechanisms of the two diseases. The lack of useful preventive measures and efficacious treatment strategies remains the largest pitfall that challenges the management of patients with PBC. In this review, we comprehensively outline the epidemiology, clinical implications and challenges, as well as management strategies of PBC-related osteoporosis.

Background: Metabolic syndrome increases adverse outcomes in coronavirus disease 2019 (COVID-19) infection. Hepatic steatosis may increase risk of COVID-19 severity. Current studies evaluating steatosis lack reliable definitions. We aimed to evaluate the association of radiographic hepatic steatosis and clinical outcomes of COV-ID-19 severity in a diverse cohort. Methods:We retrospectively identified patients with COVID-19 infection admitted to two US academic hospitals. Outcomes were length of stay, intensive care unit use, mechanical ventilation, and in-hospital mortality. We used Mann-Whitney U-test for continuous measures and Chi-square or Fisher's exact test for categorical measures. Multivariable linear and logistic regression analyses were used to adjust for confounders.Results: Of the 319 patients, 14% had hepatic steatosis. There were no differences in length of stay (6 (4 -16) vs. 9 (4 -18) days, P = 0.6), intensive care unit (24% vs.

INTRODUCTION:Anemia and micronutrient deficiencies are common in newly diagnosed patients with celiac disease (CeD). We aim to determine the prevalence and etiology of anemia in a cohort of patients with CeD in the United States and examine the effect of a gluten-free diet (GFD) on the laboratory parameters related to anemia in CeD.METHODS:We analyzed a prospectively collected cohort of adults with biopsy-proven CeD followed in a specialized CeD center between January 2000 and June 2016. We used the level of hemoglobin (Hb) and micronutrients suggested by the World Health Organization to establish the diagnosis of anemia or deficiencies. Demographic data and laboratory parameters related to anemia and micronutrients were recorded at the time of diagnosis and on a GFD. A celiac expert nutritionist or gastroenterologist evaluated all patients.RESULTS:In 572 patients with laboratory evaluation before starting a GFD, approximately 25% presented with anemia at the time of diagnosis of CeD. Iron deficiency was present in 50.8% of the cohort and in 78.8% of the patients with anemia. Within the anemic population, 84.4% of female patients as compared with 58.3% of male patients (P = 0.02) showed iron deficiency. Folate deficiency (23.2%), vitamin B12 deficiency (11%), and anemia of chronic diseases (7.8%) were also part of both sexes' anemia etiology. Of the initially anemic patients, 81% and 89% normalized their Hb levels within 1 year and 2 years of beginning a GFD, respectively. All patients received appropriate supplementation when needed.DISCUSSION:Approximately 25% of individuals have anemia at CeD diagnosis. The anemia etiology included iron deficiency, vitamin deficiencies, and anemia of chronic diseases. Most of the patients will normalize their Hb levels and the anemia laboratory parameters 1 year after starting a strict GFD.
