Personality disorders and psychiatric symptoms in psoriasis

Two groups of psoriatic outpatients (ns = 192 and 119) were given, respectively, the Million Clinical Multiaxial Inventory-II and Foulds' Delusions-Symptoms-States Inventory. They were compared with dental (n = 192) and with general surgical (n = 190) patients. The psoriatic group presented clearly higher mean scores and frequencies on most of the personality disorder scales. On Foulds' inventory, psoriatic patients showed higher frequencies of neurotic and psychotic class allocations. A cluster analysis of personality scores provided evidence for 4 different personality clusters of patients with psoriasis: (a) Avoidant, Dependent, Schizoid, and Self-defeating (32.2%), (b) Compulsive, Narcissistic, and Aggressive (30.7%), (c) no personality disorder (18.2%), (d) Borderline, Paranoid, and Schizotypal, etc. (18.8%).     

Cyclosporine A in the treatment of early rheumatoid arthritis. A prospective, randomized 24-month study

OBJECTIVE: To investigate the efficacy, tolerability and safety of cyclosporine A (CSA) in early rheumatoid arthritis (RA) patients. METHODS: Patients with an early diagnosis of RA, a disease duration of less than 3 years, and without prior disease modifying antirheumatic drug (DMARD) treatment were studied. They randomly received oral CSA (3 mg/kg/day) or oral methotrexate (MTX) (0.15 mg/kg/week). In addition, all patients in both groups received oral prednisone (7.5 mg/day). RESULTS: Fifty-two patients were assigned to the CSA group and 51 to the MTX group. After 24 months of treatment, 48 patients from the CSA group and 48 from the MTX group showed significant clinical improvement. This was evaluated by the duration of morning stiffness, grip strength, the total joint count, joint swelling, and joint tenderness and pain, compared to pre-treatment values. The clinical improvement was also associated with a significant decrease in ESR and CRP values in both groups. No significant radiological deterioration was observed in the CSA patients compared to those treated with MTX after 24 months. Four patients from the CSA group dropped out of the study, two because of a synovitis flare, one because of severe hypertrichosis and one because of severe gingival hyperplasia. Three patients from the MTX group withdrew, one because of disease flare-up and two because of gastrointestinal disturbances. CONCLUSION: Early immunointervention in RA patients appears to be crucial to limit the development of joint damage. Cyclosporine A appears to be effective, well tolerated and safe in the long-term treatment of RA and can therefore be used as a first immunomodulatory drug in the armamentarium for the treatment of RA.     

Ki-1 large cell anaplastic lymphoma--a clinicopathological study

Ki-1 large cell anaplastic lymphoma is a recently described variant of malignant lymphoma. A retrospective study of 10 cases of Ki-1 lymphoma was carried out at the Armed Forces Institute of Pathology (AFIP) Rawalpindi to document its clinical and morphological features. The morphological features were evaluated by a study of paraffin embedded sections stained with haematoxylin and eosin stains. Immunohistochemical stains for BER-H2 and leucocyte common antigen (LCA) were performed in all cases. The age of the patients ranged from 2 to 60 years and male to female ratio was 2.3:1. Cervical lymphadenopathy was the most common presentation. Histologically, there was a complete effacement of the lymph node architecture in 8 cases. The Reed-Sternberg like cells were seen in 2 and histiocyte like cells in 7 cases. Immunohistochemically all cases were positive for BER-H2. It is suggested that the possibility of Ki-1 lymphoma should be considered in all cases of lymphoma with pleomorphic morphology.     

Gastrointestinal pH profiles in patients with inflammatory bowel disease

BACKGROUND: 5-Amino salicylic acid preparations are used in therapy for patients with inflammatory bowel diseases. The bioavailability of these drugs depends on their coating. AIM: To determine whether intraluminal pH is decreased by the presence of inflammation, thereby altering the release of 5-amino salicylic acid in the intestinal lumen. METHODS: Intraluminal gastrointestinal pH was measured by means of a radiotelemetry capsule in 12 healthy controls, in 12 patients with Crohn's disease (five with active disease), and in 11 patients with ulcerative colitis (seven with active disease). RESULTS: The median gastric pH values in the patient groups (Crohn's disease 2.4, range 1.5-4.1; ulcerative colitis 1.95, range 1.55-4.4) were significantly higher than those observed in the controls (1.55, range 0.95-2.6). In the small bowel and colonic segments, all the pH values of Crohn's disease patients were comparable to those of the controls, as were the pH values in the proximal small intestine and in the left colon in patients with ulcerative colitis. However, the latter group had higher pH values in the terminal ileum, the caecum and the right colon. Patients with active disease had comparable median gastrointestinal pH values to patients in remission. CONCLUSIONS: The luminal release of 5-amino salicylic acid might not be inhibited by low pH in patients with active inflammatory bowel diseases. This supports a safe disintegration of the slow release mesalazine preparations even in the presence of severe disease.     

Comparative analysis of semiotic shifts, established by LCS of blood plasma from random samples of studied subjects from the zone of the Chernobyl accident, "Ural Radiation Trace", and collaborators from St. Petersburg Institute of Nuclear Physics of the Russian Academy of Sciences

The effects of an alternative chelation program in thalassemic patients with severe iron overload are investigated. The schedule of treatment, feasible at home, consists in the administration of deferoxamine intravenously (100 mg/kg/die 8 hours 10 days a month), followed by 50 mg/kg/die subcutaneously in the remaining 20 days of the month. The results in 34 patients who underwent this program over 8 months are reported. After intensive chelation therapy serum ferritin and transaminase levels were significantly lower, and daily urinary iron excretion values were significantly higher when compared to the levels observed before the treatment. After the period of study, echocardiography revealed an ejection fraction (EF) significantly higher in 15 out of 34 cardiopathic patients. In conclusion, the alternative chelation program is effective in reducing iron overload of thalassemic patients, protecting them also against cardiac disease.     

Murine IgG1 complexes trigger immune effector functions predominantly via Fc gamma RIII (CD16)

Previously, we have demonstrated that phagocytosis of IgG1-coated particles by macrophages in vitro is impaired by deletion of Fc gamma RIII in mice, suggesting that IgG1 may interact preferentially with Fc gamma RIII. In the present study, the biologic relevance of this observation was addressed by triggering various effector functions of the immune system in Fc gamma RIII(-/-) mice, using panels of mAbs of different IgG subclasses. Both binding and phagocytosis of IgG1-coated sheep or human erythrocytes by Fc gamma RIII(-/-) macrophages in vitro were strongly impaired, indicating that the impaired ingestion of complexed IgG1 by Fc gamma RIII(-/-) macrophages is due to a defect in binding. An in vivo consequence of the defective phagocytosis was observed by resistance of Fc gamma RIII-deficient mice to experimental autoimmune hemolytic anemia, as shown by a lack of IgG1-mediated erythrophagocytosis in vivo by liver macrophages. Furthermore, trapping of soluble IgG1-containing immune complexes by follicular dendritic cells in mesenteric lymph nodes from Fc gamma RIII(-/-) mice was abolished. Whole blood from Fc gamma RIII(-/-) mice was unable to induce lysis of tumor cells in the presence of IgG1 antitumor Abs. Finally, IgG1 mAbs proved unable to mount a passive cutaneous anaphylaxis in Fc gamma RIII(-/-) mice. Together, these results demonstrate that IgG1 complexes, either in particulate or in soluble form, trigger in vitro and in vivo immune effector functions in mice predominantly via Fc gamma RIII.
