Comparison of Dot ELISA Using GroEL Recombinant Protein as an Antigen and an Indirect Hemagglutination Assay for Serodiagnosis of Melioidosis

Kanyanan Kritsiriwuthinan, Sumet Wajanarogana, Kantima Choosang, Thitima Pimklang

Background:

Melioidosis is a disease caused by the Burkholderia pseudomallei bacterium. The mortality rate of infected patients is quite high because the symptoms are similar to those of various diseases, making it difficult to diagnose clinically and preventing the immediate treatment with effective antibiotics that is required for the management of acute infections. To provide appropriate treatment, accurate and rapid diagnosis is required.

Objective:

The aims of this study were to develop Dot ELISA using purified GroEL B. pseudomallei recombinant protein as an antigen and to compare the newly developed assay with an indirect hemagglutination assay (IHA) for the diagnosis of melioidosis.

Methods:

The GroEL recombinant protein was purified by immobilized metal affinity chromatography before being used as an antigen. The optimal conditions of the Dot ELISA were determined and used for subsequent experiments. A total of 291 serum samples were evaluated by the established Dot ELISA and IHA, using the bacterial culture method as the gold standard of melioidosis diagnosis.

Results:

The results from Dot ELISA and IHA revealed sensitivity, specificity, and accuracy of 85.7% (Dot ELISA)/64.3% (IHA), 94.4%/85.5%, and 93.1%/82.5%, respectively.

Conclusion:

These results indicate that the Dot ELISA developed is an efficient, simple, rapid and cost-effective technique for the early diagnosis of melioidosis and can be used in a local laboratory without specialized equipment.

Prevalence of Human Papillomavirus Associated with Head and Neck Squamous Cell Carcinoma in Jordanian Patients

Background:

In addition to smoking and alcohol consumption, human papillomavirus (HPV) is a leading etiology for Head and Neck Squamous Cell Carcinoma (HNSCC). However, this causal association is still understudied in Middle Eastern populations.

Objective:

The aim of this study was to determine the prevalence of HPV-associated infection in the Jordanian HNSCC patients and the associated HPV genotypes.

Methods:

Formalin-Fixed Paraffin-Embedded (FFPE) squamous cell carcinoma samples of the head and neck were collected from two referral centers in Amman, Jordan to determine the existence of HPV DNA. After DNA extraction HPV infection and genotyping were identified using real-time PCR.

Results:

HPV DNA was detected in 19 out of 61 (31.1%) HNSCC samples. Despite screening for 28 different genotypes, HPV 16 was the only genotype identified in all examined samples. Most HPV-positive samples were obtained from the oropharynx (41.7%), oral cavity (37%), and larynx (18.2%). No significant association between HPV 16 genotype and age, sex, tobacco use, anatomical location, or tumor grade was noticed.

Conclusion:

This study reported a high association between HPV 16 genotype and HNSCC in Jordanian patients. These data should facilitate the implementation of appropriate HPV awareness campaigns, and activate selective prophylactic measures against HPV infection.
