In December 2019, numerous coronavirus disease 2019 (COVID-19) cases were reported in Wuhan, China, which has since spread throughout the world. However, its impact on rheumatoid arthritis (RA) patients is unknown. Herein, we report a case of COVID-19 pneumonia in a 61-year-old female RA patient who was receiving conventional disease-modifying antirheumatic drugs (cDMARDs). The patient presented with a 4-day history of myalgia and febrile sensation. COVID-19 was confirmed by real-time polymerase chain reaction (PCR). Chest X-ray showed increased opacity on the right lower lung area, and C-reactive protein level was slightly elevated. The patient was treated with antiviral agents (lopinavir/ritonavir), and treatment with cDMARDs was discontinued except hydroxychloroquine. Her symptoms and laboratory results gradually improved. Three weeks later, real-time PCR for COVID-19 showed negative conversion, and the patient was discharged without any complications.

Objectives: The aims of our study were to determine whether the use of conventional disease-modifying antirheumatic drugs (cDMARDs) or tumor necrosis factor α (TNFα) inhibitors increase the risk of herpes zoster (HZ) in patients with ankylosing spondylitis (AS). Methods: We searched the South Korean National Health Insurance Service – National Sample Cohort Database for relevant patient records between 2002 and 2013. We evaluated the incidence of HZ by categorizing patients into in three treatment groups: disease-modifying antirheumatic drug (DMARD) nonusers, cDMARD users and TNFα inhibitor users. Results: Incidence rates of HZ was 11.0 per 1000 person-years in patients with AS. The adjusted hazard ratio of HZ was higher in cDMARD and TNFα inhibitor users than in DMARD nonusers. In subgroup analyses, current treatment with a TNFα inhibitor increased the risk of HZ significantly both in female patients and in patients aged 50 years or older, but not in patients taking steroids, compared to DMARD nonusers. Conclusions: Treatment with either TNFα inhibitors or cDMARDs is associated with a higher risk of HZ, especially in female patients and older patients, and these two patient groups could therefore benefit from HZ vaccination.

Background/Aims: Acute transverse myelitis (ATM) is a severe complication of systemic lupus erythematosus (SLE). This study evaluated the clinical factors related to outcome in patients with SLE-associated ATM. Methods: The medical records of patients diagnosed with SLE-associated ATM between January 1995 and January 2015 were reviewed. The patients were divided into two groups based on improvement of neurological deficits after treatment: favorable response group and unfavorable response group. During follow-up, the recurrence of ATM was also analyzed. Results: ATM was identified in 16 patients with SLE. All of the patients were treated with high doses of methylprednisolone (>= 1 mg/kg daily). Although 12 patients (75%) recovered (favorable response group), four (25%) had persistent neurologic deficits (unfavorable response group) after the treatment. Compared to the favorable response group, significantly higher Systemic Lupus Erythematosus Disease Activity Index-2000, lower complement levels and initial severe neurologic deficits were found in the unfavorable response group. Among the 12 favorable response patients, five (41.7%) experienced recurrence of ATM during the followup. Patients (n = 5) who experienced relapse had a shorter duration of high-dose corticosteroid treatment (13.2 days vs. 32.9 days, p = 0.01) compared to patients who did not relapse. The mean duration of tapering-off the corticosteroid until 10 mg per day was significantly longer in non-relapse group (151.3 +/- 60.8 days) than in relapse group (63.6 +/- 39.4 days, p = 0.013). Conclusions: Higher disease activity in SLE and initial severe neurologic deficits might be associated with the poor outcome of ATM. Corticosteroid slowly tapering-off therapy might be helpful in preventing the recurrence of ATM.
