Bone/joint pain and difficulty with sexual arousal are prevalent, frequently severe, and potentially treatable in patients on maintenance hemodialysis. However, the mediators and adequacy of treatment for these symptoms have been less well studied. We sought to assess the clinical correlates and treatment of these symptoms in patients receiving chronic hemodialysis. Using the Dialysis Symptom Index, we assessed the presence and severity of bone/joint pain and difficulty with sexual arousal in 75 patients on chronic hemodialysis. Associations of demographic and clinical variables with these 2 symptoms were assessed. We also recorded the use of analgesics for bone/joint pain and, among men, phosphodiesterase-5 inhibitors for difficulty with sexual arousal. Twenty-eight patients (37%) reported bone/joint pain, of whom 20 (71%) described it as moderate to severe. Nineteen of 50 male patients (38%) reported difficulty with sexual arousal, which was described as moderate to severe by 15 (79%). Patients' demographic and clinical characteristics were not correlated with bone/joint pain. Among men, there were no correlations between patients' demographic and clinical characteristics and difficulty with sexual arousal. Only 48% of patients with bone/joint pain were receiving analgesics, while 21% of men who described difficulty with sexual arousal were receiving phosphodiesterase-5 inhibitors. Demographic, clinical, and dialysis-related variables are poorly correlated with bone/joint pain and difficulty with sexual arousal. However, these symptoms are prevalent and under-treated, which should spur efforts to assess the impact of improving provider assessment and treatment of these symptoms on patient outcomes, including health-related quality of life.

An 11-year-old female patient, whose systemic type juvenile idiopathic arthritis (JIA) had maintained in remission for the previous 4 years while taking only a small amounts of ibuprofen, showed an abrupt 2nd relapse with congestive heart failure five days after receiving a live-attenuated rubella vaccine, which was a primary immunization. Her serum levels of anti-rubella IgM and IgG antibodies increased, and her laboratory findings such as a leukocytosis, elevated serum levels of CRP, IL-6 and other inflammatory cytokine profiles were similar to the findings observed during her previous JIA active stage. After being administration of co-therapy with steroid pulse, ibuprofen, methotrexate and phosphodiesterase inhibitor gradually improved her clinical symptoms such as spiky fever, heart failure and arthralgia. Her intermittent fever and increased serum levels of CRP and IL-6, however, have been sustained for more than 2 years, and this prolonged active clinical course therefore differed from her previous JIA active stage.This abrupt relapse only five days after vaccination was suggested not to be directly related with rubella infection, but instead to be related with the molecular mimicry between rubella and JIA.

Apremilast is a novel oral phosphodiesterase 4 inhibitor effective for psoriasis. It regulates the production of pro-inflammatory mediators. Apremilast was approved in December 2016 in Japan; however, its efficacy and safety in a real-world setting among Japanese patients have not been reported. We report on 44 patients treated with apremilast between March and October 2017. The median treatment duration was 25 weeks (range, 2-33). Thirty-five patients (79.5%) continued the drug for at least 23 weeks, and five (11.4%) achieved a Psoriasis Area and Severity Index 100 response within 12 weeks. Nine patients discontinued the drug within 24 weeks mainly due to insufficient efficacy (n = 3) and adverse events (n = 4). Seven patients continued their previous systemic therapies such as cyclosporin (n = 1), methotrexate (n = 1), etretinate + methotrexate (n = 1) and biologics (n = 4) combined with apremilast. Of these patients, 55.9% had at least one adverse event although no severe adverse events. The most common adverse event was diarrhea (31.8%), followed by nausea (25.0%), headache (13.6%), abdominal discomfort (6.8%) and vomiting (6.8%). The proportion of diarrhea in our patients was higher than those of previous clinical trials. Among 10 patients with psoriatic arthritis, apremilast did not improve joint pain in nine (90%). To investigate the relationship between treatment efficacy and plaque size, we defined a small plaque as an individual rash diameter of 1 inch or less. The efficacy of apremilast was greater in patients with small plaques than in patients with large plaques.
