ABSTRACT

OBJECTIVE: This study investigated the prognostic factors of anti-melanoma differentiation-associated gene 5 antibody-positive dermatomyositis (MDA5-DM). METHODS: This study analysed 34 MDA5-DM cases (20 and 14 in the survival and death groups, respectively) encountered at Kurume University between 2008 and 2021. The clinical, physiological, and computed tomography findings, pulmonary function, and serological results were retrospectively evaluated for each MDA5-DM case during the first visit and throughout the next 12 weeks. RESULTS: In the death group, the mean age of patients was higher (47.6 vs. 61.8 years), while the duration from symptom onset to consultation was shorter (110 vs. 34.9 days). During the first visit, the death group demonstrated a significantly higher serum C-reactive protein (CRP) level (0.52 vs. 1.99) and a significantly lower albumin level (3.23 vs. 2.63) than the survival group; this persisted throughout the next 12 weeks. Poor prognosis was associated with CRP and albumin levels above 0.19 mg/dL and below 2.3 g/dL, respectively, 4 weeks after starting treatment. CONCLUSION: Four weeks after beginning treatment, serum CRP and albumin levels of patients with MDA5-DM can be used to evaluate treatment response and predict prognosis.

ABSTRACT

A 70-year-old woman was hospitalised due to jaundice and fever. She was diagnosed with rheumatoid arthritis (RA) at 54 years of age. Treatment with methotrexate (MTX) was successful, and her RA was in remission. Five weeks before the hospitalisation, she was diagnosed with optic neuritis due to a decline in the visual acuity of the right eye. She was treated with methylprednisolone pulse therapy, followed by prednisolone (PSL), before the hospitalisation, which were not effective. Blood tests showed increased C-reactive protein (CRP) levels, liver injury, and thrombocytopenia. Abdominal echo revealed numerous enlarged lymph nodes in the hepatic portal region. Malignant lymphoma was suspected due to high serum levels of soluble interleukin-2 receptor. None of the treatments were effective, and she died on the fifth hospital day. Diffuse large B cell lymphoma was diagnosed during the autopsy, which showed infiltration of CD20-positive atypical lymphocytes in almost all organs. Since she was taking MTX, she was diagnosed with immunosuppressive drug-associated lymphoproliferative disease (LPD). Anti-human T-cell leukaemia virus type 1 (HTLV-1) antibody was detected in her serum after her death; however, adult T cell leukaemia/lymphoma was not observed. LPD develops during the treatment of RA with disease modifying anti-rheumatic drugs; however, a rapid clinical course leading to death is rarely observed. Previous reports suggest that T cell dysregulation observed in HTLV-1 may contribute towards the development of B cell lymphoma. We have discussed the possible roles of HTLV-1 in LPD development in this case.

ABSTRACT

RATIONALE: The ancient infectious diseases, Lemierre's Syndrome and Bezold's Abscesses are rare. PATIENT CONCERNS: A 70-year-old Japanese woman with a 15-year history of Parkinson's disease was referred to our hospital due to fever, occipital headache and bilateral shoulder pain that had continued for three months. She had been prescribed prednisolone due to a diagnosis of polymyalgia rheumatica. DIAGNOSES: A blood culture revealed bacteremia of Streptococcus constellatus. In addition, computed tomography revealed Bezold's abscesses and Lemierre's syndrome. INTERVENTIONS: We administered ceftriaxone for 31 days, followed by oral amoxicillin. OUTCOMES: The patient recovered and the abscesses improved. LESSONS: This case underscores the importance of blood culture tests and cross-referencing with radiological imagings in the diagnoses of these rare critical infectious diseases that mimic polymyalgia rheumatica.
