[Phytothermotherapy with fermenting alpine grass in knee osteoarthritis: mid-long term results]. / Fitobalneoterapia con bagni nell'erba di montagna in fermentazione nella gonartrosi: risultati a medio-lungo termine.

This is an observational study of the mid-long-term results of a single course of phytothermotherapy with grass baths (group A, 54 patients), of a course of usual medical care (group B, 58 patients) and of a course of physiokinesistherapy (FKT, group C, 30 patients) in knee osteoarthritis. For each group of consecutively treated patients we evaluated the Lequesne algo-functional Index, the drug consumption, the frequency of the patient-physician contacts and laboratory or radiological examinations after 10-15 days of treatment and at 3, 6, 9 and 12 months with blind telephonic follow-up. The mean Lequesne-score at basal time was 7.5+/-3.3, 11.9+/-5.3 and 11.0+/-2.7 in group A, B and C respectively. In each group this score diminished at the end of the treatment (p<0.001). At 3, 6, 9 and 12 months the score remained lower than at basal time in group A (p<0.001) and group B (p<0.01), but not in group C. Drug consumption, patient-physician contacts and lab examinations were 5 times lower in group A than in group B and group C at basal time and throughout the follow-up. The study underlines the mid-long term efficacy of grass baths on both pain and functionality in knee osteoarthritis; this effect, compared to basal values, was even more evident at 3 and 6 months than that of usual medical care. FKT shows improvement only at the end of the treatment, but not long-lastingly.

Anti-Saccharomyces cerevisiae and perinuclear anti-neutrophil cytoplasmic antibodies in coeliac disease before and after gluten-free diet.

BACKGROUND: Anti-Saccharomyces cerevisiae and perinuclear anti-neutrophil cytoplasmic autoantibodies are markers of Crohn's disease and ulcerative colitis respectively. AIM: To determine the prevalence of anti-S. cerevisiae and perinuclear anti-neutrophil cytoplasmic autoantibodies in a large series of coeliac disease patients before and after gluten free diet, and to correlate anti-S. cerevisiae-positivity with intestinal mucosal damage. METHODS: One hundred and five consecutive coeliac disease patients and 141 controls (22 ulcerative colitis, 24 Crohn's disease, 30 primary sclerosing cholangitis, 15 postenteritis syndrome, 50 blood donors) were tested for anti-S. cerevisiae by enzyme-linked immunosorbent assay and for perinuclear anti-neutrophil cytoplasmic autoantibodies by indirect immunofluorescence. RESULTS: In coeliac disease anti-S. cerevisiae (immunoglobulin G and/or immunoglobulin A) were slightly less frequent (59%) than in Crohn's disease (75%, P = 0.16) and significantly more frequent than in ulcerative colitis (27%), primary sclerosing cholangitis (30%), postenteritis syndrome (26%) and blood donors (4%) (P = 0.009, P = 0.0002, P = 0.025, P < 0.0001). No correlation was found between anti-S. cerevisiae and degree of mucosal damage. Perinuclear anti-neutrophil cytoplasmic autoantibodies were detected only in one coeliac. After gluten free diet the disappearance of anti-S. cerevisiae-immunoglobulin A (93%) was more frequent than that of immunoglobulin G (17%, P = 0.0001); perinuclear anti-neutrophil cytoplasmic autoantibodies disappeared in the only coeliac positive at diagnosis. CONCLUSION: More than half of untreated coeliacs are anti-S. cerevisiae-positive irrespective of the severity of mucosal damage. Differently from immunoglobulin A, anti-S. cerevisiae-immunoglobulin G persisted in more than 80% after gluten free diet. The high prevalence of anti-S. cerevisiae in coeliac disease suggests that they may be the effect of a non-specific immune response in course of chronic small bowel disease.

Anti-actin IgA antibodies in severe coeliac disease.

Anti-actin IgA antibodies have been found in sera of coeliacs. Our aim was to define the prevalence and clinical significance of anti-actin IgA in coeliacs before and after gluten withdrawal. One hundred and two biopsy-proven coeliacs, 95 disease controls and 50 blood donors were studied. Anti-actin IgA were evaluated by different methods: (a) antimicrofilament positivity on HEp-2 cells and on cultured fibroblasts by immunofluorescence; (b) anti-actin positivity by enzyme-linked immuosorbent assay (ELISA); and (c) presence of the tubular/glomerular pattern of anti-smooth muscle antibodies on rat kidney sections by immunofluorescence. Antimicrofilament IgA were present in 27% of coeliacs and in none of the controls. Antimicrofilament antibodies were found in 25 of 54 (46%) coeliacs with severe villous atrophy and in three of 48 (6%) with mild damage (P < 0.0001). In the 20 patients tested, antimicrofilaments IgA disappeared after gluten withdrawal in accordance with histological recovery. Our study shows a significant correlation between antimicrofilament IgA and the severity of intestinal damage in untreated coeliacs. The disappearance of antimicrofilament IgA after gluten withdrawal predicts the normalization of intestinal mucosa and could be considered a useful tool in the follow-up of severe coeliac disease.

[Use of nonsteroidal anti-inflammatory drugs in patients with vertebral osteoporotic fractures]. / Uso di farmaci anti-infiammatori non steroidei in pazienti con fratture vertebrali osteoporotiche.

OBJECTIVE: The aim of the study was to assess the use of Non Steroidal Anti-Inflammatory Drugs (NSAIDs) in patients with a history of osteoporotic vertebral fractures. METHODS: We investigated 119 patients with postmenopausal osteoporosis complicated by one or more non recent vertebral fractures. RESULTS: More than 60% of the patients took at least one dose of NSAID weekly. The most prescribed NSAID was nimesulide, at a dose with an exclusively antalgic effect. Patients with wedge fracture and those with a documented vertebral fracture in the last 12 months were those taking NSAIDs more frequently. 77% of the patients that used NSAIDs had concomitant features of osteoarthritis, mainly at the spine or at the knee. The use of NSAIDs was negatively related to the use of specific therapy for osteoporosis, particularly for oral daily tablets. CONCLUSIONS: This study highlights the significant use of NSAIDs in patients with osteoporotic vertebral fractures and the overlap between osteoporosis, osteoarthritis and related treatments.

Thyroid autoimmunity in chronic urticaria.

A subset of patients with idiopathic chronic urticaria (CU) has been recently classified as autoimmune on the basis of two main findings: association with thyroid autoimmunity and with anti-IgE and/or anti-IgE receptor antibodies. The association of CU with thyroid autoimmunity has been known since 1983, but its frequency varies in different reports. The objective of the present study was to verify the prevalence of thyroid antibodies (anti-thyroid peroxidase, TPO; thyroglobulin, TG; TSH-receptor, TSH-R) in two distinct series of CU: of known cause (70 cases, group A) and idiopathic (52 cases, group B). Twenty-three patients (M/F:7/16) of group A (33%) and 12 (M/F:4/8) of group B (23%) tested positive for at least one type of thyroid antibody. The difference was not statistically significant. Thyroid disease or altered serum TSH levels (requiring treatment) were present in 39% of group A and 42% of group B seropositive patients. In conclusion, the present study shows that CU, either of known cause or idiopathic, is more common in females than in males and is significantly associated with thyroid autoimmunity. These results were not expected on the assumption that autoimmune phenomena are a specific pattern of idiopathic CU. Thus, screening for thyroid autoimmunity and function is advisable in all patients with CU for the early identification of patients requiring either treatment of underlying thyroid dysfunction or follow-up.
