Establishment of the First Comprehensive Adult and Pediatric Hematopoietic Stem Cell Transplant Unit in the United Arab Emirates: Rising to the Challenge.

Hematopoietic stem cell transplantation (HSCT) is increasingly indicated for various malignant and non-malignant diseases. In the United Arab Emirates (UAE), patients that could benefit from the procedure commonly need to seek medical care abroad in view of the lack of a comprehensive HSCT facility that could offer the full spectrum of interventions and monitoring protocols. This comes with considerable challenges related to coverage and logistics of travel. It also limits the continuity of clinical care, and presents inconvenience to patients who come from a different cultural background. In this article, we share our experiences and lessons learned during the establishment of the first comprehensive adult and pediatric HSCT unit in the UAE that is designed to cater for local citizens and residents, as well as neighboring countries facing similar availability challenges.

A comparison of hospitalized children with enterovirus D68 to those with rhinovirus.

BACKGROUND: During the Fall of 2014, numerous children were hospitalized with asthma or respiratory distress related to Enterovirus D68 (EV-D68). A large proportion initially tested positive for rhinovirus. During this period our laboratory noted a cross-reactivity between EV-D68 and the rhinovirus component of the GenMark multiplex respiratory viral panel. Many other laboratories used assays not designed to distinguish these Picornoviridae. METHODS: To compare the presentation and outcomes of patients with rhinovirus and EV-D68, 103 GenMark rhinovirus positive nasopharyngeal swabs from hospitalized children were retested for EV-D68. RESULTS: EV-D68 positive patients versus EV-D68 negative patients were more likely to have a history of asthma (33.3% vs. 11.0%, P = 0.02) and to present with acute respiratory illness (66.7% vs. 40.2%, P = 0.048), especially status asthmaticus (47.6% vs. 2.4%, P < 0.001). On admission they had more wheezing, respiratory distress, and lower respiratory tract involvement, and were more likely to be treated with steroids and discharged home on asthma medications. Respiratory viral coinfection was less common in EV-D68 positive vs EV-D68 negative patients. In patients without a respiratory viral coinfection the overall findings were similar. CONCLUSION: Patients with EV-D68 versus rhinovirus were more likely to have a history of asthma, to present with status asthmaticus, to wheeze on admission, and to receive treatment with asthma medications in hospital and at discharge. The inability of common assays to distinguish EV-D68 from rhinoviruses raises the possibility that the role of EV-D68 as a viral trigger of asthma has been under appreciated.

Mycobacterium genavense-induced spindle cell pseudotumor in a pediatric hematopoietic stem cell transplant recipient: Case report and review of the literature.

We describe the first reported pediatric patient to our knowledge with a spindle cell pseudotumor caused by Mycobacterium genavense in a hematopoietic stem cell transplant recipient, and review the literature of such an entity in the transplant population.

Cirrhosis is present in most patients with hepatitis B and hepatocellular carcinoma.

BACKGROUND & AIMS: There are few data available about the prevalence or effects of cirrhosis in patients with hepatocellular carcinoma (HCC) from viral hepatitis. We compared patients with HCC and hepatitis B virus (HBV) or hepatitis C virus (HCV) infections to determine the proportions of cirrhosis in each group, virologic and tumor characteristics, and overall survival. METHODS: This analysis included patients with HBV (n = 64) or HCV (n = 118) infection who were diagnosed with HCC at the Mayo Clinic in Rochester, Minnesota from 1994-2008; groups were matched for age and sex. The diagnosis of cirrhosis was based on histology and, if histologic information was insufficient or unavailable, clinical indicators that included ascites or varices, thrombocytopenia or splenomegaly, and radiographic configuration of cirrhosis. Virologic characteristics, tumor stage, and patient survival were also assessed. RESULTS: The prevalence of histologic cirrhosis was 88% among patients with HBV infection and 93% among those with HCV infection (P = .46). When the most inclusive criteria for cirrhosis were applied, cirrhosis was present in 94% of patients with HBV and 97% with HCV (P = .24). Among HCV patients, 5.2% were negative for HCV RNA after antiviral treatment; 63.4% of HBV patients had HBV DNA <2000 IU/mL with or without treatment. Patients with HBV tended to have less surveillance and more advanced stages of HCC, without differences in survival from those with HCV infection (P = .75). CONCLUSIONS: Most patients with HCC and chronic viral hepatitis had evidence of cirrhosis, including those with HBV infection and those without active viral replication.
