Sarcoidosis is a systemic disorder of unknown etiology and is characterized by the formation of granulomas throughout various organs in the body. The most common form is pulmonary sarcoidosis, which affects 90% of patients; the second most common form is oculocutaneous sarcoidosis;¹ and the third most common form is hepatic sarcoidosis, which affects 63% to 90% of patients.² Although the liver is frequently involved in all forms of sarcoidosis, only a fraction of patients present with clinically evident liver disease.¹ Approximately 20% to 30% of patients have abnormalities on liver function tests, whereas only about 1% of patients show evidence of portal hypertension and cirrhosis.³ In fact, in the English literature, there were 35 reported cases of portal hypertension due to sarcoidosis between 1949 to 2001, of which 16 of the patients had no evidence of cirrhosis.⁴

The diagnosis of sarcoidosis is usually made by a compilation of clinical signs and symptoms, imaging studies, and biopsies demonstrating noncaseating granulomas. This case report describes a patient who presented with portal hypertension and esophageal variceal bleeding secondary to sarcoidosis of the liver without cirrhotic changes.

Case

A 47-year-old woman presented to the ED via emergency medical services with a 1-hour history of hematemesis and melena. The patient stated that she felt fatigued, nauseated, and light-headed, but had no pain or focal weakness. Her medical history was significant for pulmonary and renal sarcoidosis. She underwent a liver biopsy 1 week prior to presentation, with a 6-day hospitalization period, due to new ascites found on examination.

The patient’s vital signs at presentation were: blood pressure (BP), 72/56 mm Hg; heart rate (HR), 133 beats/min, respiratory rate, 24 breaths/min; and temperature, 97.0^oF. Oxygen saturation was 99% on room air. Physical examination revealed an alert and oriented middle-aged woman in extremis who was vomiting dark-colored blood. The cardiac and pulmonary examination revealed no extraneous sounds; the abdominal examination showed ascites with a liver edge palpable 4 cm beneath the right costal margin. The patient had no scleral icterus, palmar erythema, spider angiomata, fetor hepaticus, caput medusa, cutaneous ecchymoses, or any other stigmata of cirrhosis.

Two large-bore peripheral intravenous (IV) catheters were placed and a massive blood transfusion protocol was initiated. Packed red blood cells (PRBCs) from the resuscitation-area refrigerator were infused immediately via a pressurized fluid warmer.

After consultation with gastroenterology and general surgery services, the patient was given 1 g ceftriaxone IV, 1 g tranexamic acid IV, 20 mcg desmopressin IV, 50 mcg octreotide IV, 40 mg pantoprazole IV, 8 mg ondansetron IV, 4 g calcium gluconate IV, and 100 mg hydrocortisone IV.

Throughout the patient’s first 10 minutes in the ED, she remained persistently hypotensive and continued to vomit. Since the patient’s sensorium was intact, the team quickly discussed goals of care with her. The patient’s wishes were for maximal life-sustaining therapy, including endotracheal intubation and chest compressions, if necessary.

After this discussion, the patient was given IV etomidate and rocuronium and was intubated using video-assisted laryngoscopy. Following intubation, she was sedated with an infusion of fentanyl and underwent orogastric tube placement to aspirate stomach contents. A total of 2.5 L of frank blood were drained from the patient’s stomach.

A size 9 French single lumen left-femoral central venous catheter also was placed, through which additional blood products were infused. The patient received a total of 28 U PRBCs, fresh frozen plasma, and platelets over a 3-hour period. During transfusion, the patient’s vital signs improved to a systolic BP ranging between 110 to 120 mm Hg and an HR ranging between 90 to 110 beats/min; she did not experience any further hypotensive episodes throughout her stay in the ED.

Laboratory studies were significant for metabolic acidosis, hyperkalemia, acute on chronic anemia, leukocytosis, and acute on chronic renal failure. Synthetic function of the liver and transaminases appeared normal (Table).

Discussion

Etiology

Esophageal variceal hemorrhage is caused by pressure elevation in the portal venous system, leading to engorged esophageal veins that can bleed spontaneously. Approximately 90% of portal hypertension is due to liver cirrhosis.⁵ The remaining 10% of cases are primarily vascular in etiology, with endothelial dysfunction and thrombosis leading to increased portal resistance. Noncirrhotic causes of portal hypertension include malignancy, congenital diseases, viral hepatitides, vascular thromboses or fistulae, constrictive pericarditis, fatty liver of pregnancy, drugs, radiation injury, and infiltrative diseases.⁵

Sarcoidosis may cause noncaseating granulomas to form in the liver, leading to portal hypertension and fatal exsanguination from esophageal variceal hemorrhage. Although the lesions of sarcoidosis classically form in the lungs, any organ system may be affected.^6,7 Frank cirrhosis of the liver occurs in only 1% of sarcoidosis patients; however, radiographic involvement of the liver is seen in 5% to 15% of patients.⁸

There are several mechanisms which may be responsible for portal hypertension in patients with sarcoidosis, including granulomas causing mass effect on the hepatic sinusoids; arteriovenous shunts within the granuloma; granulomatous phlebitis within the sinusoids; or compressive periportal lymphadenopathy.⁹ Regardless of the mechanism, a review of the literature demonstrates an association between sarcoidosis and symptomatic portal hypertension.^2,4,10,11Although our patient ultimately died, early initiation of massive blood transfusion protocol, airway protection, attention to electrolytes, and endoscopic control of the hemorrhage source provided the best chance for survival.

Medical Therapy

The first priority in managing and treating esophageal varices is to secure the patient’s airways to prevent aspiration. Two large bore IV lines should be placed to permit rapid infusion of crystalloid fluids or blood products. Initiating antibiotics, specifically IV ceftriaxone, to patients with variceal bleeding is a class I recommendation, as this is the only intervention shown to increase patient survival.¹² Although proton pump inhibitors (PPI) and somatostatin analogues (typically octreotide) are frequently given, they are both class II recommendations because there is limited evidence supporting the benefit of their use.¹² However, current guidelines recommend treating patients for variceal bleeding with an initial bolus of a PPI, followed by a continuous infusion of PPI for 72 hours. As previously noted, multiple studies, have failed to show any decrease in mortality associated with this treatment.¹²

Other agents that are used to treat variceal bleeding include octreotide and vasopressin. Octreotide, a somatostatin analog, is generally given as an initial IV bolus followed by continuous infusion, and has been shown to decrease transfusion requirements without mortality benefit.¹² Vasopressin is generally given to critically ill patients, and is considered a third-line treatment for variceal bleeding.

Since our patient had a history of chronic kidney disease, desmopressin was empirically administered in the event platelet dysfunction was a contributing factor to bleeding.¹³ The absence of cirrhosis was significant because our patient was unlikely to have a bleeding diathesis caused by coagulation factor deficiency. Therefore, the goal transfusion ratio of blood products should be balanced, similar to that in traumatic exsanguination, rather than favoring an increased ratio of plasma to other blood products. Similarly, tranexamic acid was administered because insufficient tamponade rather than coagulopathy was the presumed cause of sustained hemorrhage.

An additional complicating factor in our patient’s care was the potential effect of the massive transfusion on electrolytes. Packed RBCs have a pH of approximately 6.8 and may carry up to 25 mmol/L of potassium, which may have exacerbated our patient’s underlying hyperkalemia.¹⁴ Rapid blood transfusion also places patients at risk for acute hypocalcemia secondary to citrate toxicity; this did not occur in our patient in part because the metabolic function of her liver was preserved and citrate could be broken down in the hepatocyte Krebs cycle.¹⁵ Calcium therapy doubled as treatment for the hyperkalemia and as prophylaxis against further hypocalcemia. No dysrhythmias were observed.

Surgical Intervention

Emergency physicians should consult with gastroenterology services so that an endoscopy can be performed as soon as possible to evaluate for and control bleeding. When an endoscopy cannot be performed rapidly, there are multiple balloon tamponade devices available that can be used to temporize the bleeding, such as the Sengstaken-Blakemore tube.¹²

Although balloon tamponade devices are typically reserved for the last line of therapy, endoscopy rather than transjugular intrahepatic portosystemic shunt (TIPS) was the preferred method of hemorrhage source control in our patient for several reasons. First, although the working diagnosis of varices was based on the patient’s history, we wanted to evaluate for other causes of upper gastrointestinal bleeding since our patient had no history of endoscopy. Therefore, endoscopy had both a therapeutic and diagnostic value. Secondly, though TIPS may decrease pressure within the bleeding varix, only endoscopy permits direct hemostasis. Also, endoscopy also was preferred over TIPS because our patient was too unstable to move to the interventional radiology suite.¹⁶

Conclusion

Although life-threatening esophageal variceal hemorrhage is a rare manifestation of an uncommon disease, it should be considered in the differential diagnosis of a patient who has sarcoidosis and presents with gastrointestinal bleeding. Additionally, when caring for a patient with massive hematemesis without evidence of liver cirrhosis, other etiologies of portal hypertension and esophageal varices, such as sarcoidosis, should be considered.

Sarcoidosis is a systemic disorder of unknown etiology and is characterized by the formation of granulomas throughout various organs in the body.

TORONTO – While C-reactive protein, procalcitonin, and proadrenomedullin are associated with development of severe clinical outcomes in children with lower respiratory tract infections, proadrenomedullin is most strongly associated with disease severity, preliminary results from a prospective cohort study showed.

“Despite the fact that pneumonia guidelines call the site of care decision the most important decision in the management of pediatric pneumonia, no validated risk stratification tools exist for pediatric lower respiratory tract infections (LRTI),” lead study author Todd A. Florin, MD, said at the annual Pediatric Academic Societies meeting. “Biomarkers offer an objective means of classifying disease severity and clinical outcomes.”

Doug Brunk/MDedge News

Preliminary data that Dr. Florin presented at PAS found that the median CRP, PCT, and proADM did not differ by gender, race, ethnicity, or insurance status. “In addition, there were not significant differences in the distribution of disease severity by biomarker performed, with approximately 27% of patients being classified as mild, 66% as moderate, and 7% as severe,” he said.

The median CRP was 2.4 ng/mL in those with mild disease, 2.5 ng/mL in those with moderate disease, and 6.25 ng/mL in those with severe disease, with the difference between the two subclasses of nonsevere disease and moderate disease and severe disease reaching statistical significance (P = .002). The median PCT was 0.16 ng/mL in those with mild disease, 0.26 ng/mL in those with moderate disease, and 0.49 ng/mL in those with severe disease, with the difference between the two subclasses of nonsevere disease and moderate disease and severe disease reaching statistical significance (P = .047). Meanwhile, the median proADM was 0.53 ng/mL in those with mild disease, 0.59 ng/mL in those with moderate disease, and 0.81 ng/mL in those with severe disease, with the difference between the two subclasses of nonsevere disease and moderate disease and severe disease also reaching statistical significance (P less than .0001).

Next, the researchers performed logistic regression of each biomarker individually and in combination. They found that proADM alone was associated with the largest odds for severe LRTI disease (odds ratio, 13.1), compared with CRP alone (OR 1.6) and PCT alone (OR 1.4), and had the best ability to discriminate those developing severe vs. nonsevere disease (area under the receiving operating curve of 0.72, vs. 0.67 and 0.60, respectively). When CRP and PCT markers were combined with proADM, they were no longer associated with severe disease, while a strong association with proADM remained significant.

Dr. Florin acknowledged certain limitations of the study, including the fact that requiring collection of blood samples may have resulted in an enrollment bias toward patients receiving phlebotomy or IV line placement in the ED. “In addition, the children in the moderate-severity group are likely more heterogeneous than the other two severity groups,” he said. “Finally, given that this is a single-center study, we had a relatively small number of outcomes for some of the individual severity measures, which may have limited power and precision.”

He concluded his presentation by saying that he is “cautiously optimistic” about the study results. “As is the case in many biomarker studies, I do not anticipate that any single biomarker will be the magic bullet for predicting disease severity in pediatric CAP,” Dr. Florin said. “It will likely be a combination of clinical factors and several biomarkers that will achieve optimal prognostic ability. That said, our results suggest that similar to adult studies, proADM appears to have the strongest association with severe disease, compared with CRP and PCT. Combinations of biomarkers did not perform better than proADM alone. With the advent of rapid point-of-care diagnostics, these markers may have a role in management and site-of-care decisions for children with LRTI.”

The study received funding support from the Gerber Foundation, the National Institute of Allergy and Infectious Diseases, and Cincinnati Children’s Hospital Medical Center. Dr. Florin reported having no financial disclosures.

Dr. Florin acknowledged certain limitations of the study, including the fact that requiring collection of blood samples may have resulted in an enrollment bias toward patients receiving phlebotomy or IV line placement in the ED. “In addition, the children in the moderate-severity group are likely more heterogeneous than the other two severity groups,” he said. “Finally, given that this is a single-center study, we had a relatively small number of outcomes for some of the individual severity measures, which may have limited power and precision.”

He concluded his presentation by saying that he is “cautiously optimistic” about the study results. “As is the case in many biomarker studies, I do not anticipate that any single biomarker will be the magic bullet for predicting disease severity in pediatric CAP,” Dr. Florin said. “It will likely be a combination of clinical factors and several biomarkers that will achieve optimal prognostic ability. That said, our results suggest that similar to adult studies, proADM appears to have the strongest association with severe disease, compared with CRP and PCT. Combinations of biomarkers did not perform better than proADM alone. With the advent of rapid point-of-care diagnostics, these markers may have a role in management and site-of-care decisions for children with LRTI.”

TORONTO – While C-reactive protein, procalcitonin, and proadrenomedullin are associated with development of severe clinical outcomes in children with lower respiratory tract infections, proadrenomedullin is most strongly associated with disease severity, preliminary results from a prospective cohort study showed.

“Despite the fact that pneumonia guidelines call the site of care decision the most important decision in the management of pediatric pneumonia, no validated risk stratification tools exist for pediatric lower respiratory tract infections (LRTI),” lead study author Todd A. Florin, MD, said at the annual Pediatric Academic Societies meeting. “Biomarkers offer an objective means of classifying disease severity and clinical outcomes.”

Preliminary data that Dr. Florin presented at PAS found that the median CRP, PCT, and proADM did not differ by gender, race, ethnicity, or insurance status. “In addition, there were not significant differences in the distribution of disease severity by biomarker performed, with approximately 27% of patients being classified as mild, 66% as moderate, and 7% as severe,” he said.

The median CRP was 2.4 ng/mL in those with mild disease, 2.5 ng/mL in those with moderate disease, and 6.25 ng/mL in those with severe disease, with the difference between the two subclasses of nonsevere disease and moderate disease and severe disease reaching statistical significance (P = .002). The median PCT was 0.16 ng/mL in those with mild disease, 0.26 ng/mL in those with moderate disease, and 0.49 ng/mL in those with severe disease, with the difference between the two subclasses of nonsevere disease and moderate disease and severe disease reaching statistical significance (P = .047). Meanwhile, the median proADM was 0.53 ng/mL in those with mild disease, 0.59 ng/mL in those with moderate disease, and 0.81 ng/mL in those with severe disease, with the difference between the two subclasses of nonsevere disease and moderate disease and severe disease also reaching statistical significance (P less than .0001).

Next, the researchers performed logistic regression of each biomarker individually and in combination. They found that proADM alone was associated with the largest odds for severe LRTI disease (odds ratio, 13.1), compared with CRP alone (OR 1.6) and PCT alone (OR 1.4), and had the best ability to discriminate those developing severe vs. nonsevere disease (area under the receiving operating curve of 0.72, vs. 0.67 and 0.60, respectively).

WASHINGTON – Though the liver safety of statins in patients with low-level liver enzyme elevations has long been established, some providers still hesitate to prescribe them to the patients with the conditions for which they are indicated.

Nonalcoholic fatty liver disease (NAFLD), hyperlipidemia, metabolic syndrome, and diabetes, which often co-occur, are also involved in cardiovascular disease. Cardiovascular disease is the most common cause of mortality in NAFLD, before liver disease.

Sonal Kumar, MD, MPH, of New York–Presbyterian Hospital described in a video interview at the annual Digestive Disease Week^® a study she and her colleagues conducted to evaluate statin use in patients with hyperlipidemia by using data from the National Health and Nutrition Examination Survey during 2005-2014 (NHANES). Adult patients aged over 18 years were included if they did not have viral hepatitis, did not excessively consume alcohol, were not pregnant, and did not have transaminase levels over 500 IU/L.

Statin use was assessed in 136,833,627 participants by NHANES interviewers. Of these participants, 74.6% had hyperlipidemia (defined as LDL cholesterol greater than 130 mg/dL) and 93.5% were taking a statin. Patients with hyperlipidemia with abnormal alanine aminotransferase values were significantly less likely to be taking a statin (86.3% vs. 89.1%, P = .001). With multivariate analysis, abnormal ALT significantly decreased the odds of patients receiving a statin if they had diabetes (odds ratio, 0.75; 95% confidence interval, 0.57-0.99) when sex and age were controlled for.

Statins are underutilized in patients with NAFLD and diabetes, patient groups in whom they could help control cardiovascular disease risk factors, said Dr. Kumar. Providers need to be educated on the safety of statins in these patients to improve cardiovascular outcomes.

WASHINGTON – Catheter-directed clot lysis and thrombectomy with creation of a bypass shunt is a reasonable alternative to prolonged anticoagulation for treating patients with portal vein thrombosis (PVT) based on the accumulated reported experience since 1993 using this percutaneous treatment.

Use of a transjugular intrahepatic portosystemic shunt (TIPS) for treating portal vein thrombosis (PVT) “is feasible and effective in achieving a significant and sustainable reduction in clot burden with a low risk of major complications,” Nelson Valentin, MD, said at the annual Digestive Disease Week.^® “TIPS should be considered a viable treatment option for patients with PVT,” said Dr. Valentin, a gastroenterology fellow at Mount Sinai Beth Israel hospital in New York.

Mitchel L. Zoler/MDedge News

“There is sufficient evidence from these reports to at least consider TIPS as an adjunct to anticoagulation or perhaps as primary therapy,” especially for patients with PVT who have a contraindication for anticoagulation, Dr. Valentin said in an interview. Standard anticoagulation for PVT would today involve acute treatment with a low-molecular-weight heparin followed by oral anticoagulation for a total treatment time of at least 6 months and continued for a year or longer in some patients. A recently published review of reported experience using anticoagulation to treat PVT found a complete recanalization rate of 41% and a complete or partial rate of 66%, which suggests that TIPS is at least as effective, although Dr. Valentin cautioned that no reported study has directly compared the two alternative approaches. A study designed to make this direct comparison is warranted by the reported results using TIPS, Dr. Valentin said. And the experience with TIPS positions it as an option for patients who do not respond to anticoagulation or would prefer an alternative to prolonged anticoagulation.

One factor currently limiting use of TIPS, which is usually performed by an interventional radiologist, is that the procedure is technically demanding, with a limited number of operators with the expertise to perform it. If TIPS became more widely accepted as an option for treating PVT, then the pool of interventionalists experienced with performing the procedure would grow, Dr. Valentin noted.

CHICAGO – Denosumab may be preferable to bisphosphonates in myeloma patients in specific scenarios, G. David Roodman, MD, PhD, reported at the annual meeting of the American Society of Clinical Oncology.

“We use denosumab in patients with compromised renal function,” said Dr. Roodman, director of the Division of Hematology-Oncology at Indiana University, Indianapolis, noting one such scenario. That use of denosumab echoes recently published ASCO guidelines on bone-modifying therapy.

Andrew D. Bowser/MDedge News

The addition of denosumab was based in part on results of a recent randomized phase 3 trial that comprised 1,718 myeloma patients who were treated with either denosumab or zoledronic acid.

The primary endpoint, time to first on-study skeletal-related event, was evaluated after 676 skeletal-related events had accrued on study. The investigators found no difference in time to first event (hazard ratio [HR], 0.98; 95% confidence interval, 0.85-1.14; P = 0.82).

Likewise, the secondary endpoint of overall survival showed no difference between arms (HR, 0.90; 95% CI, 0.70-1.16), though an exploratory analysis did suggest denosumab was superior on the endpoint of progression-free survival (HR, 0.82; 95% CI, 0.68-0.99).

The ASCO guidelines also recommend that clinicians consider less-frequent dosing in patients with responsive or stable disease. That recommendation is based on results of two studies of less-frequent dosing prompted by concerns over the risk of osteonecrosis of the jaw, an uncommon but potentially serious complication associated with bone-modifying agents.

Both studies suggested every-3-months dosing of zoledronic acid could be effective. However, Dr. Roodman noted that both studies had limitations that need to be considered, including small numbers of myeloma patients, limited duration of therapy studied, and a high dropout rate in the case of one study. Due to those limitations, “it’s very difficult to draw conclusions about this today,” Dr. Roodman said.

Dr. Roodman reported that he had a consulting or advisory role with Amgen.
