BackgroundBiotherapy is becoming increasingly important in the treatment of adult-onset Still’s disease (AOSD). The aim of our study was to evaluate the efficacy and safety of biological therapy for AOSD resistant to traditional therapy.Patients and methodsDatabase of Library of Congress, the PubMed, and Web of Science Core Collection were used to retrieve relevant articles published in English language until March 2017. Only studies published in English language were included, and the additional references quoted in these articles were also checked. Articles concerning the efficacy and safety of all the biotherapies in refractory AOSD were evaluated.ResultsThere were 112 articles available in total; 422 AOSD patients were given at least one biologic. We found that 293 patients (69.43%) had received TNF-α blocking agents (infiliximab, etanercept, and adalimumab), 194 patients (45.97%) were treated with IL-1 receptor antagonists (anakinra, rilonacept, and canakinumab), 163 patients (38.63%) were given IL-6 inhibitor (tocilizumab), and 24 patients (5.69%) received rituximab and abatacept. The efficacy of biological therapy and overall tolerance of biological therapy for refractory AOSD were good. Thirty two of 271 patients given anti-TNF-α therapies (11.81%), 116 patients receiving IL-1 inhibitors (65.54%), 124 patients receiving tocilizumab (76.07%), and 13 patients given other biological therapies (36.11%) achieved remission. Side effects of biologic therapy were infections such as urinary tract infections and soft tissue abscess.ConclusionOur findings suggest that anakinra and tocilizumab may be good choices for the treatment of refractory AOSD considering the effectiveness and safety.

A newly identified DNA virus, named TT virus (TTV), was found to be related to transfusion-associated hepatitis. We conducted the following experiments to evaluate its pathogenic role in liver disease and potential modes of transmission. We used PCR to detect TTV DNA in serum. The rates of TTV viremia in 13 patients with idiopathic acute hepatitis, 14 patients with idiopathic fulminant hepatitis, 22 patients with chronic hepatitis, and 19 patients with cirrhosis of the liver were 46, 64, 55, and 63%, respectively, and were not significantly different from those in 50 healthy control subjects (53%). PCR products derived from seven patients with liver disease and three healthy controls were cloned and then subjected to phylogenetic analyses, which failed to link a virulent strain of TTV to severe liver disease. TTV infection was further assessed in an additional 148 subjects with normal liver biochemical tests, including 30 newborns (sera collected from the umbilical cord), 23 infants, 16 preschool children, 21 individuals of an age prior to that of sexual experience (aged 6 to 15 years), 15 young adults (aged under 30 years), and 43 individuals older than 30 years. The rates of TTV viremia were 0, 17, 25, 33, 47, and 54%, respectively. These findings suggest that TTV is transmitted mainly via nonparenteral daily contact and frequently occurs very early in life and that TTV infection does not have a significant effect on liver disease.

Aims Persistent pruritic eruptions (PPEs), presenting with dyskeratotic keratinocytes histologically, are characteristic skin rash in patients with adult‐onset Still's disease (AOSD). The lesions may be histologically similar to other entities that present with dyskeratosis. In the present study, we compared the histopathological features between PPEs and other entities presenting with dyskeratosis. Methods and results To investigate whether histopathological findings can be used to discriminate among PPEs and other entities presenting with dyskeratotic keratinocytes, cutaneous histopathological changes of PPEs associated with AOSD (n = 26) were compared with those of systemic lupus erythematosus (SLE) (n = 16), dermatomyositis (n = 19), and drug eruption (n = 16). Dyskeratosis was observed in the upper one‐third of the epidermal layer in all 26 PPEs. The rate of dyskeratosis for PPEs was higher than that for SLE (18.8%) and dermatomyositis (15.8%). In drug eruptions, the dyskeratotic cells were distributed in all levels of the epidermis. Variable densities of neutrophils were found in the dermis in all PPEs. Conclusions Although this was a retrospective study conducted at a single centre, presentation of dyskeratotic keratinocytes in the upper one‐third of the epidermal layer is a distinctive histopathological reactive pattern of PPEs. This pattern may be a useful histopathological marker for early diagnosis of AOSD.

A755 pharmacy. Written consent was obtained from the participants prior to the interview. Results: Among the respondents interviewed. Thematic content analysis yielded 4 major themes: (a) Lack of documentation, (b) Improper patient counseling, (c) Unavailability of pharmaceutical care guidelines, (4) Lack of collaboration with other health care providers. ConClusions: This study concludes that community pharmacies are not very much involved in provision of pharmaceutical care to patients. Documentation and patient counseling is also very poor due to lack of enough time and no financial encouragement. There is also no effective professional relationship of community pharmacists with other health care providers.

We report the case of a 54-year-old woman with concurrent Sweet's syndrome, pathergy phenomenon and eythema nodosum-like lesions associated with suppurative tonsillitis. Tender, violaceous and highly edematous papules and plaques were detected on the forearms and legs, some of which were pseudovesicular. Similar edematous papules were detected on the dorsum of the hands at the sites of intravenous injection. Biopsies of a plaque on the forearm and a papule at the site of intravenous injection confirmed the presence of Sweet's syndrome. Multiple, tender, violet-red, subcutaneous erythematous nodules were revealed on the legs. A biopsy taken from a nodule on the leg revealed septal panniculitis. To our knowledge, no patient with concurrent Sweet's syndrome, pathergy phenomenon, and erythema nodosum-lesions had been reported yet in previous literature.
