Résumé

Background: Previous studies correlating Th1 and Th2 cytokine profiles with psoriasis activity provided inconsistent results. Correlation of tissue cytokine levels with psoriasis severity has not been studied till now. Objective: To compare serum and tissue Th1 and Th2 cytokine profiles of patients with active and stable psoriasis as well as healthy controls, and to correlate them with psoriasis severity. Methodology: This was a cross-sectional study involving adult patients with 'active' psoriasis (untreated progressive chronic plaque psoriasis, guttate psoriasis, and erythrodermic psoriasis), 'stable' psoriasis (stable plaque psoriasis or those with completely resolved lesions) and healthy subjects with non-inflammatory skin lesions as controls. Mean levels of Th1 and Th2 cytokines in serum [interleukin 2 (IL-2), interferon-gamma (IFN-γ), IL-4, IL-10] and tissue mRNA expression (IFN-γ, IL-4) were compared among these three groups. Results: There were 30 patients each in active and stable psoriasis groups, and 15 in the control group. Mean serum IL-2, IFN-γ, and IL-10 levels of patients with psoriasis patients were significantly higher than the controls (P < 0.001 for both active and stable psoriasis), whereas mean serum IL-4 level of patients was significantly lower than the controls (P < 0.001). However, there was no statistically significant difference of serum cytokine levels between active and stable psoriasis groups. Mean quantitative tissue mRNA expression of IFN-γ and IL-4 of patients with active and stable psoriasis were significantly lower than the controls (P < 0.001 and <0.01, respectively), but were not significantly different between active and stable psoriasis groups. Serum and tissue cytokines showed weak correlation with psoriasis area and severity index. Limitations: Small sample size and heterogenous nature of patients with psoriasis in terms of disease activity, morphology and treatment are limitations of this study. Conclusions: There is no significant change in the serum or tissue levels of Th1 and Th2 cytokines with activity or severity of psoriasis.

Résumé

Several large scale clinical trials have demonstrated that angiotensin converting enzyme inhibitors offer cardiovascular and renal protection independent of their effects on systolic BP. Trandolapril is a new angiotensin converting enzyme inhibitor approved for the treatment of hypertension. The potential advantages of this drug are long duration of action and better tolerability. The objective of the study was to compare the efficacy and tolerability of trandolapril with that of enalapril in mild to moderate hypertension in Indian population. In this double blind, multicentric, parallel comparative clinical study, 120 patients with mild to moderate hypertension were randomly assigned to receive trandolapril 2 mg or enalapril 5 mg once daily for 8 weeks. The attainment of sitting diastolic blood pressure <90 mmHg at the end of 8th week was considered as primary outcome measure and attainment of diastolic blood pressure <90 mmHg or reduction of at least 10 mmHg diastolic blood pressure compared to baseline at any visit was considered as secondary outcome measures. 98.4% patients treated with trandolapril and 92.6% patients treated with enalapril fulfilled the primary outcome measure. 54, 72 and 62% patients on trandolapril and 52, 61 & 64% patients on enalapril fulfilled secondary outcome measure at the end of 2nd, 4th and 8th week respectively. Also trandolapril was better tolerated than enalapril with no significant abnormality in lab parameters.

Résumé

In unstable angina (USA) patients, immunological responses contributing to inflammation play a vital role in plaque rupture and thrombosis causing stroke. In the present study an attempt is made to estimate the levels of adenosine deaminase activity, an immunoenzyme marker and C-reactive protein, a marker of inflammation in USA patients. 45 patients presenting USA and 50 age and sex matched healthy controls were included in the study. Serum ADA activity was measured spectrophotometrically at 630nm and serum C-reactive protein was detected using Avitex CRP kit, which is a rapid latex agglutination test. The Mean ADA levels were 41.15 ± 11.04 in patients and 20.71±5.63 in controls and 66.6% of patients and none of the controls were positive to CRP. The present study observed the importance of ADA as a serum marker in addition to CRP for assessing the immune response in USA patients.
