RESUMO

Hepatitis B reactivation can occur with various forms of immunosuppression. Cyclophosphamide, Bortezomib, and Dexamethasone (CYBOR-D) chemotherapy is commonly used for the treatment of multiple myeloma and has not been noted in guidelines to be causative in HBV reactivation. Indeed, current guidelines do not recommend providing antiviral prophylaxis to patients with prior HBV infection. We present a case of HBV reactivation as a result of CYBOR-D and autologous stem cell transplant which is complicated by the patient's partner who developed acute hepatitis B. Our case highlights the need to review the role of antiviral prophylaxis for patients undergoing treatment of multiple myeloma and also the role of ensuring immunity for close contacts of these patients who may also be at risk.

RESUMO

BACKGROUND: The aim of the study was to compare serum sclerostin levels in human im-munodeficiency virus (HIV)-infected patients and healthy controls, and to evaluate their relationship with bone turnover markers (BTM) and bone mineral density (BMD). METHODS: We prospectively studied 33 HIV treatment-naive patients and 63 healthy individuals; matched for age and sex. Serum sclerostin levels, BTM, BMD were measured. Viral load and cluster of differentiation 4 (CD4) levels were also assessed in HIV-infected patients. RESULTS: The mean±standard deviation (SD) age of sample was 37.6±10.3 years (range, 19 to 59 years). Of the 96 subjects, 58 (60.4%) were male and 38 (39.6%) were female. Infection with HIV is associated with significant reduction in serum sclerostin levels (HIV-infected: 39.4±28.3 vs. non HIV: 76.6±15.7 pmol/L; P<0.001) and a decrease in BMD at femoral neck and lumbar spine compared to healthy controls. Sclerostin however was not correlated with BMD and was not related to age, generally a strong correlation. There were no significant correlations between sclerostin and BTM (P>0.05). CONCLUSIONS: These findings suggest that untreated HIV and the resulting immune deficiency and/or systemic inflammation could be an important regulator of serum sclerostin in this population.

RESUMO

BACKGROUND/AIMS: Evidence-based medicine has established itself in the field of gastroenterology. In this study we aim to assess the types of study designs of gastroenterology-related articles published in Saudi scientific journals. PATIENTS AND METHODS: An online review using PubMed was carried out to review gastroenterology-related articles published in six Saudi medical journals in the time interval from 2003 to 2012. To classify the level of evidence in these articles we employed the Oxford's levels of evidence. One-way analysis of variance was used to compare the levels of evidence between published articles. RESULTS: A total of 721 gastroenterology-related articles were reviewed, of which 591 articles met our inclusion criteria; 80.7% were level IV. The three most common types of studies we encountered were cross-sectional (33.9%), case reports (27.9%), and case series (18.8%). Forty-three percent of the published research was in the field of hepatobiliary and spleen. The total number of articles increased from 260 articles in the 1 st 5-year period (2003-2007) to 330 in the 2 nd period (2008-2012). However, no statistically significant difference in the level of evidence was noted. In Annals of Saudi Medicine Journal, articles with level II increased from 0 to 10% with a P value 0.02. CONCLUSION: In our review of gastroenterology-related published articles in Saudi scientific journals, we observed an increase in the quantity of articles with the quality and level of evidence remaining unchanged. Further research is recommended to explore different reasons affecting the volume and quality of gastroenterology-related research in Saudi scientific journals.
