We undertook a prospective study of 23 male patients with Ankylosing Spondylitis (AS) (New York Criteria), 18 HLA-B27 positive and 5 HLA-B27 negative, five of them had hyperuricemia. The following data of evolution were taken into consideration: age at onset of disease, time course of the disease, presence of urolithiasis, heart disease, flares of uveitis. Clinical activity and degree of disability were evaluated every one to 3 months; on each visit, every patient had determinations of serum and urinary uric acid levels, serum and phosphorus, erythrocyte sedimentation rate (ESR), serum protein electrophoresis, as well as X-ray films of the vertebral spine and pelvis. Three groups of patients were detected, all of them with equal age at onset, duration of disease, frequency of B27, peripheral arthritis, and leukocytosis. One group had hyperuricemia (5 of 23 patients, 80% of them HLA-B27 positive) and a lesser degree of clinical activity of the disease (p less than .001, a higher frequency of uveitis (40%, lower levels of serum gammaglobulins (p less than 0.05) and ESR (p less than 0.05), a lesser degree of ankylosis of the spine, and a better functional prognosis than the other groups. Another group (8 of 23 patients, 75% of them were HLA-B27 positive) had normouricemia and hyperuricosuria, and showed a higher frequency of fever (50%), an abnormal urinalysis, and urolithiasis (25%).

Twenty-three dogs with a diagnosis of leishmaniosis (clinical stage II) were treated with meglumine antimoniate and allopurinol and were followed up for 2-9 years. The treatment showed efficacy and the clinical condition of the dogs improved markedly in the first 3 months of treatment. Anti-Leishmania antibody titres declined slowly although most dogs remained seropositive 1 year after beginning treatment. Inter-individual variability in the evolution of the titres was very high. The dogs presented with three types of complications during the follow-up period. (1) Three dogs experienced relapses characterized by clinical signs, high anti-Leishmania titres and high parasitaemia. (2) Eight dogs presented immune-mediated lesions, such as uveitis, arthritis and cutaneous vasculitis; in all of these cases, the dogs had high titres of anti-Leishmania antibodies at diagnosis and during follow-up. (3) Three dogs presented xanthine urolithiasis most likely due to the allopurinol treatment. In one case the xanthine uroliths led to hydronephrosis and nephrectomy. The study demonstrated a long survival for dogs with leishmaniosis treated with the combination of meglumine antimoniate and allopurinol. Clinicians should pay special attention to the appearance of immune-mediated lesions, especially in dogs with sustained high antibody titres, and to urolithiasis.
