Epstein-Barr virus expression in Hodgkin's lymphoma in Kuwait

Area of Science:

• Oncology
• Virology
• Epidemiology

Background:

• Hodgkin's lymphoma (HL) exhibits geographical variations in histological subtypes and Epstein-Barr virus (EBV) association.
• Data on HL epidemiology and EBV in the Persian Gulf and Middle East are scarce.
• EBV association with HL varies globally, being low in industrialized, high in non-industrialized, and intermediate in early-industrialized nations.

Purpose of the Study:

• To determine the epidemiology of Hodgkin's lymphoma in Kuwait, an early-industrialized Persian Gulf nation.
• To assess the association between Epstein-Barr virus and Hodgkin's lymphoma in this region.

Main Methods:

• Retrospective review of 134 Hodgkin's lymphoma cases for histology and demographics.
• Immunohistochemistry (IHC) for LMP1 and in-situ hybridization (ISH) for EBER used to detect EBV in 107 cases.
• Analysis of histological subtypes, patient demographics, and EBV expression rates.

Main Results:

• Mixed cellularity HL (45.5%) was the most common subtype, followed by nodular sclerosis (37.3%).
• EBV expression was detected in 56% of cases, higher in mixed cellularity, children, and males.
• The male:female ratio was 2.4:1, with a mean age of 30.6 years.

Conclusions:

• The frequency of EBV expression in Hodgkin's lymphoma in Kuwait aligns with patterns observed in other early-industrialized countries.
• Findings contribute to understanding HL epidemiology and EBV association in the Middle East.
• Further regional studies are needed to fully elucidate HL epidemiology and EBV's role in the Persian Gulf and Middle East.
