Burden of alcohol use disorder and its consequences in Iran from 1990 to 2019: Findings from the global burden of disease study.

Background: This study aimed to provide an up-to-date evaluation of the burden of alcohol use disorder and its consequences in Iran from 1990 to 2019. Methods: We assessed the burden of alcohol use disorder and its three subsequent disorders, including cirrhosis and other chronic liver diseases, liver cancer, and cardiomyopathy using Global Burden of Disease (GBD) data. We retrieved data on incidence, prevalence, death, Years of Life Lost from mortality (YLL), Years of healthy life Lost due to Disability (YLD), and Disability-Adjusted Life Year (DALY), which is calculated by summing YLL and YLD values, indices, as well as sociodemographic index (SDI) values. Results: Age-standardized DALY rate of alcohol use disorder reduced from 55.5 in 1990 to 41.8 per 100,000 in 2019 (-24.1 %). Similarly, age-standardized DALY rates of cirrhosis due to alcohol use (-28.7 %), liver cancer due to alcohol use (-20.9 %), and alcoholic cardiomyopathy (-36.3 %) decreased in Iran from 1990 to 2019. In 2019, alcohol use disorder had the highest DALY rate among individuals younger than 55 years, while cirrhosis due to alcohol use imposed the greatest burden on those older than 55. After adjusting for the year, SDI was negatively associated with the age-standardized DALY rate of liver cancer due to alcohol use (p < 0.001), positively associated with that of alcoholic cardiomyopathy (p = 0.002), and not significantly associated with the burden of other conditions (p > 0.05). Conclusions: Despite reductions in the age-standardized DALY rate of alcohol use disorders and related consequences among Iranians, they remain a serious public health concern in Iran.

Case Report of a Novel NFkB Mutation in a Lymphoproliferative Disorder Patient.

BACKGROUND: Lymphoproliferative disorders include a heterogeneous list of conditions that commonly involve dysregulation of lymphocyte proliferation resulting in lymphadenopathy and bone marrow infiltration. These disorders have various presentations, most notably autoimmune manifestations, organomegaly, lymphadenopathy, dysgammaglobulinemia, and increased risk of chronic infections. CASE PRESENTATION: A young boy presented with symptoms overlapping different lymphoproliferative disorders, including episodes of chronic respiratory tract infections, dysgammaglobulinemia, lymphadenopathy-associated with splenomegaly as well as skin rashes. Genetic studies revealed multiple heterozygous variants, including a novel mutation in the NFκB1 gene. CONCLUSION: This novel mutation can reveal new aspects in the pathogenesis of lymphoproliferative disorders and propose new treatments for them.
