This is a cross-sectional study that analyzed the pattern and frequency of articular and ophthalmologic manifestations in patients with Crohn's disease (CD) and ulcerative colitis (UC), with or without signs of active bowel inflammation. One hundred and thirty consecutive patients with CD (n = 71) and UC (n = 59) were examined. Simple X-rays of lumbar spine, sacroiliac joints, and calcaneal bone were performed and human leukocyte antigen (HLA)-B27 was typed. Joint manifestations occurred in 41 (31.5%) patients, 27 (38%) with CD and 14 (23.7%) with UC. Peripheral involvement occurred in 22 patients, axial involvement in five, and mixed involvement in 14. The most frequently involved joints were knees (56.1%), ankles (29.3%), and hips (29.3%), while the predominant pattern was oligoarticular (84.6%) and asymmetrical (65.6%). Enthesitis was identified in seven (5.4%) patients and inflammatory lumbar pain in 13 (10%). Eight of these patients fulfilled the diagnostic criteria for ankylosing spondylitis (6.2%). Radiographic sacroiliitis occurred in 12 patients (9.2%). Ocular abnormalities were present in six patients (6.2%), and HLA-B27 was positive in five (5.8%). In conclusion, the articular manifestations in the present study were predominantly oligoarticular and asymmetric, with a low frequency of ophthalmologic involvement and positive HLA-B27.

The evaluation of the efficacy of an immunochemotherapy protocol to treat symptomatic dogs naturally infected with Leishmania chagasi was studied. This clinical trial had the purpose to test the combination of N-methyl meglumine antimoniate (Glucantime and the second generation recombinant vaccine Leish-110f plus the adjuvant MPL-SE to treat the canine leishmaniasis (CanL). Thirty symptomatic naturally infected mongrel dogs were divided into five groups. Animals received standard treatment with Glucantime or treatment with Glucantime Leish-110f + MPL-SEas immunochemotherapy protocol. Additional groups received Leish-110f + MPL-SE only, MPL-SE only, or placebo. Evaluation of haematological, biochemical (renal and hepatic function) and plasmatic proteins, immunological (humoral and cellular immune response) and the parasitological test revealed improvement of the clinical parameters and parasitological cure in dogs in both chemotherapy alone and immunochemotherapy cohorts. However, the immunotherapy and immunochemotherapy cohorts had reduced number of deaths, higher survival probability, and specific cellular reactivity to leishmanial antigens, in comparison with chemotherapy cohort only and control groups (adjuvant alone and placebo). These results support the notion of using well-characterized recombinant vaccine as an adjunct to improve the current chemotherapy of CanL.
