JALLER RAAD, Juan et al. Immunological response of a population from the Caribbean region of Colombia infected with the chikungunya virus. Rev.Colomb.Reumatol. [online]. 2016, vol.23, n.2, pp.85-91. ISSN 0121-8123.

Introduction: Chikungunya virus infection has become a public health problem, due to its immediate effect on the health and quality of life of patients and their families, as well as complications in the medium and long term. Its necessary to determine immunological characteristics of this afection as an important step for the future development of strategies to reduce its incidence and aggressiveness. Objective: To characterize immunologically a population from Colombian Caribbean with serologic and clinic diagnosis of chikungunya virus infection. Material and methods: A descriptive, longitudinal, and prospective study was conducted on in 109 patients with a clinical diagnosis and serological confirmation of chikungunya virus infection and attended in the emergency department of the Fundación Hospital Universitario Metropolitano and the Orthopaedic and Rheumatology Centre. Immunoglobulin G or M type antibodies against Chikungunya virus were determined in a peripheral blood sample using immuno-enzymatic serological and immunological test in order to diagnose rheumatic diseases. Results: Tests were positive for immunoglobulin G type antibodies against chikungunya virus in all of the 109 patients. The results for anti-cyclic citrullinated peptide antibodies, rheumatoid factor, antinuclear, and anti-DNA antibodies were negative in almost all of the 109 patients. Conclusion: Patients were not in a viral replication process that characterizes the acute phase of the disease. There were no positive results in laboratory test related to rheumatic diseases. High concentrations of certain pro-inflammatory interleukins were found in patients, and the clinical manifestations in these, suggest an inflammatory joint process with severe arthralgia that can mimic the symptoms of a rheumatic disease.
