Prevalence and Characteristics of Hyperthyroidism Among Patients With Sarcoidosis in the United States.

OBJECTIVE: We aimed to determine the prevalence and clinical characteristics of self-reported hyperthyroidism in patients with sarcoidosis. METHODS: A national registry-based study investigating 3836 respondents to the Sarcoidosis Advanced Registry for Cures questionnaire in the period between June 2014 and August 2019 was conducted. This registry is generated from a web-based questionnaire that is self-reported by patients with sarcoidosis. We compared patients with sarcoidosis who had hyperthyroidism with those who did not. We used multivariate logistic regression analysis to study the association between hyperthyroidism and different cardiac manifestations in patients with sarcoidosis. RESULTS: Three percent of the study respondents self-reported having hyperthyroidism and were generally middle-aged Caucasian women. Compared with patients without hyperthyroidism, patients with hyperthyroidism had more sarcoidosis-related comorbidities (59% vs 43%, P = .001) and more steroid-related comorbidities (56% vs 44%, P = .01), but there was no difference in the sarcoidosis-specific treatments they received, which included corticosteroids. Patients with hyperthyroidism reported sarcoidosis involvement of the heart (26.6% vs 14.9%, P = .005), kidneys (14.9% vs 8%, P = .033) and sinuses (17.7% vs 10.2%, P = .030) more frequently. Cardiac manifestations that were more frequently reported in patients with hyperthyroidism included atrial arrhythmias (11.3% vs 6.3%, P = .046), ventricular arrhythmias (17.2% vs 7.5%, P < .001), congestive heart failure (10.4% vs 5%, P = .017), and heart block (9.4% vs 4.7%, P = .036). CONCLUSION: Hyperthyroidism is infrequent in patients with sarcoidosis but is potentially associated with different cardiac manifestations. We suggest considering routine screening for hyperthyroidism in patients with sarcoidosis, especially in those with cardiac involvement. Further studies are needed to investigate the impact of identifying and treating hyperthyroidism in patients with sarcoidosis.

SERUM LEVELS OF CARCINOEMBRYONIC ANTIGEN IN PATIENTS WITH TYPE 2 DIABETES.

OBJECTIVE: To investigate whether serum carcinoembryonic antigen (CEA) levels are associated with type 2 diabetes mellitus (T2DM) and glycated hemoglobin (HbA1c). METHODS: A comparative, cross-sectional, observational study was conducted at Jordan University Hospital, Amman, Jordan, on 282 adult subjects from March 2012 to June 2015. Subjects were classified into 2 groups: T2DM subjects (n = 168) and a healthy comparison group (n = 114). Subjects with any condition known to be associated with elevated CEA levels were excluded. HbA1c and serum CEA levels were measured, and body mass index (BMI) was determined. RESULTS: Subjects with T2DM had significantly higher mean serum CEA than controls (2.4 ± 1.5 vs. 1.5 ± 1.2 ng/mL, P<.0001). Sex did not correlate with CEA levels, while age (Spearman's rho [ρ] = 0.18, P = .002) and HbA1c (ρ = 0.56, P<.0001) did; however, age no longer correlated after correcting for diabetic status. HbA1c was the only variable shown to correlate with CEA in a stepwise linear regression (r = 0 .37, P<.001). CONCLUSION: We observed a statistically significant association between elevated CEA and T2DM, despite average CEA values for both groups being within the reference range. In addition, serum CEA levels correlated positively with HbA1c values.

Prevalence and characteristics of self-reported hypothyroidism and its association with nonorgan-specific manifestations in US sarcoidosis patients: a nationwide registry study.

Little is known about the prevalence, clinical characteristics and impact of hypothyroidism in patients with sarcoidosis. We aimed to determine the prevalence and clinical features of hypothyroidism and its relation to organ involvement and other clinical manifestations in patients with sarcoidosis. We conducted a national registry-based study investigating 3835 respondents to the Sarcoidosis Advanced Registry for Cures Questionnaire between June 2014 and August 2019. This registry is based on a self-reported, web-based questionnaire that provides data related to demographics, diagnostics, sarcoidosis manifestations and treatment. We compared sarcoidosis patients with and without self-reported hypothyroidism. We used multivariable logistic regression and adjusted for potential confounders to determine the association of hypothyroidism with nonorgan-specific manifestations. 14% of the sarcoidosis patients self-reported hypothyroidism and were generally middle-aged white women. Hypothyroid patients had more comorbid conditions and were more likely to have multiorgan sarcoidosis involvement, especially with cutaneous, ocular, joints, liver and lacrimal gland involvement. Self-reported hypothyroidism was associated with depression (adjusted odds ratio (aOR) 1.3, 95% CI 1.01-1.6), antidepressant use (aOR 1.3, 95% CI 1.1-1.7), obesity (aOR 1.7, 95% CI 1.4-2.1), sleep apnoea (aOR 1.7, 95% CI 1.3-2.2), chronic fatigue syndrome (aOR 1.5, 95% CI 1.2-2) and was borderline associated with fibromyalgia (aOR 1.3, 95% CI 1-1.8). Physical impairment was more common in patients with hypothyroidism. Hypothyroidism is a frequent comorbidity in sarcoidosis patients that might be a potentially reversible contributor to fatigue, depression and physical impairment in this population. We recommend considering routine screening for hypothyroidism in sarcoidosis patients especially in those with multiorgan sarcoidosis, fatigue and depression.

Cocaine Use and Pulmonary Hypertension.

Evidence linking cocaine to the risk of pulmonary hypertension (PH) is limited and inconsistent. We examined whether cocaine use, in the absence of other known causes of PH, was associated with elevated systolic pulmonary artery pressure (sPAP) and increased probability of PH. We compared patients with documented cocaine use to a randomly selected age, sex, and race-matched control group without history of cocaine use. All participants had no known causes of PH and underwent echocardiography for noninvasive estimation of sPAP. We used routinely reported echocardiographic parameters and contemporary guidelines to grade the probability of PH. In 88 patients with documented cocaine use (mean age ± standard deviation 51.7 ± 9.5 years), 33% were women and 89% were of Black race. The commonest route of cocaine use was smoking (74%). Cocaine users compared with the control group had significantly higher sPAP (mean ± standard deviation, 30.1 ± 13.1 vs 22.0 ± 9.8 mm Hg, p <0.001) and greater likelihood of PH (25% vs 10%, p = 0.012). In multivariable analyses adjusted for potential confounders including left ventricular diastolic dysfunction, cocaine use conferred a fivefold greater odds of echocardiographic PH (p = 0.006). Additionally, a stepwise increase in the likelihood of PH was noted across cocaine users with negative or no drug screen on the day of echocardiography to cocaine users with a positive drug screen (multivariable p for trend = 0.008). In conclusion, cocaine use was associated with a higher sPAP and an increased likelihood of echocardiographic PH with a probable acute-on-chronic effect.

Iatrogenic Right-Sided Pneumothorax Presenting as ST-Segment Elevation: A Rare Case Report and Review of Literature.

Pneumothorax is a well-recognized complication of central venous line insertion (CVL). Rarely, pneumothorax can lead to electrocardiogram (ECG) findings mimicking ST-segment elevation myocardial infarction. We present a 63-year-old man with iatrogenic right-sided pneumothorax who developed ST-segment elevation on a 12-lead ECG suggestive of myocardial infarction. The ECG findings completely resolved after needle decompression and chest tube placement. This case points up this rare electrocardiographic finding with discussion of possible mechanisms and differential diagnosis.
