ABSTRACT
ABSTRACT Background: Musculoskeletal inflammatory lesions in chronic Chikungunya virus (CHIKV) infection have not been thoroughly assessed using whole-body magnetic resonance imaging (WBMRI). This study aimed to determine the prevalence of these lesions in such patients. Methods: From September 2018 to February 2019, patients with positive Chikungunya-specific serology (Immunoglobulin M/Immunoglobulin G anti-CHIKV), with a history of polyarthralgia for > 6 months prior to MRI with no pre-existing rheumatic disorders, underwent 3T WBMRI and localized MRI. The evaluation focused on musculoskeletal inflammatory lesions correlated with chronic CHIKV infection. Pain levels were assessed using a visual analogue scale on the same day as WBMRI. Results: The study included 86 patients of whom 26 met the inclusion criteria. All patients reported pain and most (92.3%) categorized it as moderate or severe. The most common finding across joints was effusion, particularly in the tibiotalar joint (57.7%) and bursitis, with the retrocalcaneal bursa most affected (48.0%). Tenosynovitis was prevalent in the flexor compartment of the hands (44.2%), while Kager fat pad and soleus edema were also observed. Bone marrow edema-like signals were frequently seen in the sacroiliac joints (19.2%). Most WBMRI findings were classified as mild. Conclusions: This study represents the first utilization of 3T WBMRI to assess musculoskeletal inflammatory disorders in chronic CHIKV infection. The aim was to identify the most affected joints and prevalent lesions, providing valuable insights for future research and clinical management of this condition regarding understanding disease pathophysiology, developing targeted treatment strategies, and using advanced imaging techniques in the assessment of musculoskeletal manifestations.
ABSTRACT
Adult Still’s disease is rare and may present as pyrexia of unknown origin. Due to lack of expertise, diagnosis may be delayed inadvertently. The patient usually presents with spiked fever, polyarthralgia or arthritis, evanescent skin rash, non-purulent pharyngitis, lymphadenopathy and hepatosplenomegaly. Leukocytosis, predominantly of neutrophils, elevated erythrocyte sedimentation rate and C-reactive protein without obvious infection are the hallmarks of the disease. Delay in diagnosis may expose the patient to the side effects of antibiotics as they are repeatedly prescribed in view of elevated leukocytes. The majority of patients report pain in the throat without evidence of infection. This was an important clue to our diagnosis of this patient. Grossly elevated serum ferritin is diagnostic of adult onset still's disease. As the white cell counts are grossly elevated, a bone marrow examination to rule out hematological malignancy may be mandatory. Serum ferritin value has prognostic value too. Minor illness may respond to non-steroidal anti-inflammatory drugs (NSAIDs), but steroids are the mainstay of the treatment. Methotrexate is of additional value for those presenting predominantly with arthritis. Anakinra, Infliximab and Tocilizumab are other options. Those patients presenting with severe disease and organ involvement require high dose intravenous steroids followed by high dose oral steroids.
ABSTRACT
Background: To describe the diversity of clinical manifestations, laboratory findings and outcome of chikungunya fever in patients attending SMS Hospital, Jaipur during the epidemic of 2016 (September to November).Methods: All cases of febrile illness with polyarthralgia/polyarthritis diagnosed as chikungunya were analyzed. Diagnosis was made by ELISA based IgM serology and RT PCR assay.Results: A total of 200 cases were studied. All of them presented with fever, severe crippling joint pain & tenderness, headache, anorexia and body rash. On examination, there was periarticular edema, erythema, and tenderness in joints with post auricular and cervical lymphadenopathy. Unusual manifestations were hyper pigmentation of face and forehead and scrotal ulcers. On investigations patient had leucopenia with elevated level of SGOT, SGPT with normal bilirubin levels. Other complications observed were encephalopathy, encephalitis, myocarditis and hepatitis. There was no mortality in this group.Conclusions: Chikungunya though prevalent is under-reported. The diagnostic certainty is mandated by presence of febrile transiently crippling polyarthragias / arthritis. On analyzing a large series, unusual clinical features may emerge
ABSTRACT
BACKGROUND:The Chikungunya (CHIK) virus was recently reported by the CDC to have spread to the United States. We report an early documented case of CHIK from the state of Pennsylvania after a patient recently returned from Haiti in June of 2014. METHODS:A 39-year-old man presented to the emergency department complaining of fever, fatigue, polyarthralgias and a diffuse rash for two days. Four days before, he returned from a mission trip to Haiti and reported that four of his accompanying friends had also become ill. A CHIK antibody titer was obtained and it was found to be positive. During his hospital stay, he responded well to supportive care, including anti-inflammatories, intravenous hydration and anti-emetics. RESULTS:His condition improved within two days and he was ultimately discharged home. CONCLUSIONS:Manifestations of CHIK can be similar to Dengue fever, which is transmitted by the same species of mosquito, and occasionally as a co-infection. Clinicians should include Chikungunya virus in their differential diagnosis of patients who present with fever, polyarthralgia and rash with a recent history of travel to endemic areas, including those within the United States.
