Hemophagocytic lymphohistiocytosis in inflammatory bowel disease: a nationwide analysis.

Hemophagocytic lymphohistiocytosis (HLH) is a rare but life-threatening immune dysregulation disease. Patients with inflammatory bowel disease (IBD) can become profoundly immunocompromised due to immunosuppressive therapy, hence increasing the risk of viral infections that can trigger HLH. However, data on the association between IBD and HLH remains limited. We used data from the National Inpatient Sample (2012-2019) utilizing International Classification of Diseases (ICD)-9 or ICD-10 codes to identify individuals with IBD, either Crohn's disease (CD) or ulcerative colitis (UC), and HLH. The primary outcome was to compare the prevalence of HLH among patients with IBD with those without IBD. Secondary outcomes included in-hospital mortality, mean hospital length of stay, and description of HLH-associated triggers in IBD patients. A total of 513,322 hospitalizations included a diagnosis of IBD, 188,297 had UC and 325,025 had CD. Compared to the general population, patients with IBD were older (median age of 52 vs. 49 years, p < 0.05), more likely to be male, and of Asian/Pacific Islander descent, and had a higher median household income. There was also a higher prevalence of liver disease, autoimmune diseases, tobacco abuse, and hypothyroidism (all had p-value of < 0.001) in IBD patients. There were 94 hospitalizations identified with a diagnosis of HLH in IBD patients. Compared to patients without IBD, patients with IBD had increased odds of developing HLH (0.02% vs 0.01%, p-value < 0.001). After adjusting for various demographic characteristics, co-morbidities, and HLH-related conditions, IBD was an independent predictor for developing HLH (adjusted OR, 2.3; 95% CI, 1.847-2.866, p-value of < 0.001). There was no statistical difference between CD and UC in the odds of developing HLH. Compared to IBD patients without HLH, patients with IBD and HLH had a lower mean age at diagnosis (38 vs 52, p-value of < 0.001), higher in-hospital mortality (14.9% vs 1.5%, p-value of < 0.001), and longer mean hospital length of stay (days) (17 vs 5.4, p-value of < 0.001). Prevalence of different HLH-associated illnesses was identified in HLH patient's discharge data. Lymphoma was the most common associated malignancy (18.1%) and cytomegalovirus infection was the most common associated infection (16.0%). Our population-based study suggests that IBD is independently associated with developing HLH. Early recognition of IBD patients presenting with features suggestive of HLH is warranted to aide early diagnosis and aggressive treatment.

Supporting Smokers in Difficult Settings: Suggestions for Better Education and Counseling in Cancer Centers in Jordan.

Continued smoking in cancer patients is commonly observed in Jordan. In a country that exhibits some of the highest smoking rates globally, enhancing patient education regarding the value of smoking cessation for cancer care is vital. The objectives of our study were to describe sociodemographic and clinical factors associated with continued smoking in Jordanian smokers after a cancer diagnosis; to identify reasons for smoking and knowledge regarding smoking's impact on care; to examine in a multivariable manner the factors associated with continued smoking, and to accordingly generate patient counseling recommendations. An interviewer-administered survey using the Theoretical Domains Framework was employed. Among 350 subjects (mean age 51.0, median 52.7), approximately 38% of patients had quit or were in the process of quitting; 61.7% remained smokers. Substantial knowledge gaps with regard to the impact of continued smoking on cancer care were observed. Remaining a smoker after diagnosis was associated with being employed, not receiving chemotherapy or surgery, having lower confidence in quitting, and having a lower number of identified reasons for smoking. Interventions to promote cessation in Jordanian cancer patients who smoke should focus on enhancing patient awareness about the impact of smoking in cancer care and raising perceived self-efficacy to quit.

Cessation experiences and quitting perspectives of Jordanian cancer patients who smoke.

OBJECTIVES: To describe quitting experiences of cancer patients in a Cancer Center in Jordan; to study patients' perceptions regarding the process of smoking cessation; and to provide insights about patients in this difficult setting in order to inform oncology practitioners with regards to how improve perceptions and skills related to quitting. METHODS: An Arabic cross-sectional questionnaire was developed to evaluate smoking and quitting behaviors in the context of cancer. The tool used as its framework the Theoretical Domains Framework to capture quitting perceptions of cancer patients who smoke, as well as social, environmental, and system-level factors that influence quitting. Eligible patients who were treated at the Center (both in-patient and out-patient settings) and who were current smokers or who smoked up to the time of cancer diagnosis were eligible. Patients were interviewed between July, 2018 and January 2020 using two versions of the questionnaire: an 'ex-smokers' version, and a 'current smokers' version. RESULTS: Only a third of subjects (104/350) had been smoke-free for at least 30 days. Both smokers and ex-smokers generally felt that quitting was important, but mean importance and confidence scores (out of 10) were significantly lower in current smokers (8.2 versus 9.1, p-value=0.002; 6.4 versus 8.7, p-value=0.000). Roughly 31% of subjects believed smoking harms were exaggerated and that smoking was not an addiction. About 62% of subjects agreed quitting required skills, and 78.5% felt the steps to quit were clear, but across several listed strategies for quitting, use of these was limited (even in ex-smokers). Among current smokers, roughly a third exhibited forms of cessation fatigue. CONCLUSION: Jordanian cancer patients who smoke present with limited knowledge about the quitting process. Even when some success is observed, low rates of utilization of specific quitting strategies were observed, highlighting the need for better counseling about quitting.

Atrial fibrillation in cancer patients who develop stroke.

BACKGROUND: Acute ischemic stroke (Stroke) and transient ischemic attacks (TIA) are known complications in cancer patients and those with atrial fibrillation (AF). The role AF plays in Stroke/TIA in the setting of cancer is unclear. The purpose of this study was to assess the relationship between AF and Stroke/TIA in cancer patients. METHODS: We conducted a case-control study comparing all patients who developed Stroke/TIA from 2014 to 2019 following a cancer diagnosis at King Hussein Cancer Center (KHCC), matched to Stroke/TIA-free controls based on age, gender, and cancer site. RESULTS: Two hundred seventy-two patients were included (136 per group). The mean age was 63.95 ± 13.06 and 57% were females. The Stroke/TIA group had more AF at the time of event (14% vs. 4%, OR: 4.25, 95%-CI: 1.39 - 17.36) and had a larger proportion of death on study conclusion (OR: 9.4, 95%-CI: 3.74 - 23.64). On conditional logistic regression, patients in the Stroke/TIA group had higher odds of: AF (OR: 7.93, 95%-CI: 1.6 - 39.18), ischemic stroke before cancer diagnosis (OR: 9.18, 95%-CI: 2.66 - 31.74), being on active cancer treatment (OR: 3.11, 95%-CI: 1.46 - 6.62), dyslipidemia (OR: 3.78, 95%-CI: 1.32 - 10.82), and renal disease (OR: 4.25, 95%-CI: 1.55 - 11.63). On another conditional logistic regression model built to assess the role of the CHA2DS2-VASc score, a score of >=2 in males and >=3 in females significantly increased the risk of developing Stroke/TIA in cancer patients (OR: 2.45, 95%-CI: 1.08 - 5.58). CONCLUSION: AF, previous ischemic stroke, active cancer treatment, dyslipidemia, and renal disease are independent risk factors for Stroke/TIA and a higher CHA2DS2-VASc score significantly increases the risk in cancer patients regardless of AF.

Vitamin B12 Deficiency Among the Healthy Jordanian Adult Population: Diagnostic Levels, Symptomology and Risk Factors.

BACKGROUND: Compared to the data available for developed countries, there is a marked scarcity of information on the levels and symptomology of vitamin B12 deficiency in developing countries, particularly in the Middle Eastern region. OBJECTIVE: To explore (a) the risk factors associated with a deficiency of vitamin B12, and (b) the baseline (cut-off) serum level of vitamin B12 for a clinically-symptomatic deficiency in the Jordanian adult population. METHODS: A total of 485 subjects were included in this study. Blood samples were drawn for biochemical analysis and data regarding socio-demographics, general health, anthropometric measures, and past medical, surgical, and medication history were collected. To explore the cut-off point, we compared all parameters included in a standard complete blood count as well as the main symptoms reported to be associated with B12 deficiency between groups of different B12 cut-off values, consisting of those above and below 200, 175, 150 and 125 pg/ml. RESULTS: Low dairy intake habits, age, recurrent headaches, heartburn, and peptic ulcer disease were found to be significantly associated with lower vitamin B12 levels. Surprisingly, daily smoking was associated with significantly higher B12 levels. The results revealed that none of the included potential indicators of B12 deficiency could be considered an indicative feature of deficiency. There were no significant differences neither in the symptoms nor in the CBC parameters between any of the tested study groups. CONCLUSION: Low dairy intake, older ages, recurrent headaches, heartburn, and peptic ulcer disease all could be considered as risk factors of having low vitamin B12 levels within the Jordanians. Also, they tend to have lower levels of vitamin B12 levels, in comparison to countries in the West, without necessarily having deficiency symptoms. The cut-off value to diagnose functional B12 deficiency could be less than 125 pg/ml for the Jordanians. More local studies are needed to establish an accurate vitamin B12 cut-off value for the population in Jordan.
