Thiopurines related malignancies in inflammatory bowel disease: Local experience in Granada, Spain.

AIM To investigate the incidence of neoplasms in inflammatory bowel disease (IBD) patients and the potential causative role of thiopurines. METHODS We performed an observational descriptive study comparing the incidence of malignancies in IBD patients treated with thiopurines and patients not treated with these drugs. We included 812 patients which were divided in two groups depending on whether they have received thiopurines or not. We have studied basal characteristics of both groups (age when the disease was diagnosed, sex, type of IBD, etc.) and treatments received (Azathioprine, mercaptopurine, infliximab, adalimumab or other immunomodulators), as well as neoplasms incidence. Univariate analysis was performed with the student t test, χ(2) test or Wilcoxon exact test as appropriate. A logistic regression analysis was performed as multivariate analysis. Statistical significance was establish at P values of less than 0.05, and 95%CI were used for the odds ratios. RESULTS Among 812 patients included, 429 (52.83%) have received thiopurines: 79.5% azathioprine, 14% mercaptopurine and 6.5% both drugs. 44.76% of patients treated with thiopurines and 46, 48% of patients who did not receive this treatment were women (P > 0.05). The proportion of ulcerative colitis patients treated with thiopurines was 30.3% compare to 66. 67% of patients not treated (P < 0.001). Mean azathioprine dose was 123.79 ± 36.5 mg/d (range: 50-250 mg/d), mean usage time was 72.16 ± 55.7 mo (range: 1-300 mo) and the accumulated dose along this time was 274.32 ± 233.5 g (1.5-1350 g). With respect to mercaptopurine, mean dose was 74.7 ± 23.9 mg/d (range: 25-150 mg/d), mean usage time of 23.37 ± 27.6 mo (range: 1-118 mo), and the accumulated dose along this time was 52.2 ± 63.5 g (range: 1.5-243 g). Thiopurine S-methyltransferase activity was tested in 66% of patients treated with thiopurines, among which 98.2% had an intermediate or high activity. Among the patients treated with thiopurines, 27.27% (112 patients) and 11.66% (50 patients) received treatment with Infliximab and Adalimumab respectively, but only 1.83% (7 patients) and 0.78% (3 patients) received these drugs in the group of patients who did not received thiopurines (P < 0.001 and P < 0.001 respectively). Finally, 6.8% (29 patients) among those treated with thiopurines have received other immunesupresants (Methotrexate, Tacrolimus, Cyclosporin), compare to 1% (4 patients) of patients not treated with thiopurines (P < 0.001). Among patients treated with thiopurines, 3.97% developed a malignancy, and among those not treated neoplasms presented in 8.1% (P = 0.013). The most frequent neoplasms were colorectal ones (12 cases in patients not treated with thiopurines but none in treated, P < 0.001) followed by non-melanoma skin cancer (8 patients in treated with thiopurines and 6 in not treated, P > 0.05). CONCLUSION In our experience, thiopurine therapy did not increase malignancies development in IBD patients, and was an efective and safe treatment for these diseases.

Trans-scleral local resection of toxic choroidal melanoma after proton beam radiotherapy.

AIM: To report on trans-scleral local resection of choroidal melanoma for exudative retinal detachment and neovascular glaucoma (toxic tumour syndrome) after proton beam radiotherapy (PBR). METHODS: A non-randomised, prospective study of secondary trans-scleral local resection of choroidal melanoma for exudative retinal detachment with or without neovascular glaucoma after PBR. The patients were treated at the Liverpool Ocular Oncology Centre between February 2000 and April 2008. The trans-scleral local resection was performed with a lamellar-scleral flap, using systemic hypotension to reduce haemorrhage. RESULTS: 12 patients (six women, six men) with a mean age of 51 years (range 20-75) were included in this study. The tumour margins extended anterior to ora serrata in six patients. On ultrasonography, the largest basal tumour dimension averaged 12.4 mm (range 6.8-18.1) and the tumour height averaged 7.1 mm (range 4.2-10.7). The retinal detachment was total in seven patients. Neovascular glaucoma was present in four patients. The time between PBR and local resection had a mean of 17.4 months (range 1-84). The ophthalmic follow-up time after the local resection had a mean of 46.2 months (range 14-99). At the latest known status, the eye was conserved in 10 patients, with a flat retina in all these patients and visual acuity equal or better than 6/30 in four patients. The reasons for enucleation were: patient request for enucleation when rhegmatogenous retinal detachment complicated the resection (one patient) and phthisis (one patient). CONCLUSIONS: Exudative retinal detachment, rubeosis and neovascular glaucoma after PBR of a choroidal melanoma can resolve after trans-scleral local resection of the tumour. Our findings suggest that these complications are caused by the persistence of the irradiated tumour within the eye ('toxic tumour syndrome').

BDNF overexpression in mouse hippocampal astrocytes promotes local neurogenesis and elicits anxiolytic-like activities.

The therapeutic activity of selective serotonin (5-HT) reuptake inhibitors (SSRIs) relies on long-term adaptation at pre- and post-synaptic levels. The sustained administration of SSRIs increases the serotonergic neurotransmission in response to a functional desensitization of the inhibitory 5-HT1A autoreceptor in the dorsal raphe. At nerve terminal such as the hippocampus, the enhancement of 5-HT availability increases brain-derived neurotrophic factor (BDNF) synthesis and signaling, a major event in the stimulation of adult neurogenesis. In physiological conditions, BDNF would be expressed at functionally relevant levels in neurons. However, the recent observation that SSRIs upregulate BDNF mRNA in primary cultures of astrocytes strongly suggest that the therapeutic activity of antidepressant drugs might result from an increase in BDNF synthesis in this cell type. In this study, by overexpressing BDNF in astrocytes, we balanced the ratio between astrocytic and neuronal BDNF raising the possibility that such manipulation could positively reverberate on anxiolytic-/antidepressant-like activities in transfected mice. Our results indicate that BDNF overexpression in hippocampal astrocytes produced anxiolytic-/antidepressant-like activity in the novelty suppressed feeding in relation with the stimulation of hippocampal neurogenesis whereas it did not potentiate the effects of the SSRI fluoxetine on these parameters. Moreover, overexpressing BDNF revealed the anxiolytic-like activity of fluoxetine in the elevated plus maze while attenuating 5-HT neurotransmission in response to a blunted downregulation of the 5-HT1A autoreceptor. These results emphasize an original role of hippocampal astrocytes in the synthesis of BDNF, which can act through neurogenesis-dependent and -independent mechanisms to regulate different facets of anxiolytic-like responses.

No major impact of skin aging on the response of skin blood flow to a submaximal local thermal stimulus

La peau est sujette à un vieillissement intrinsèque (processus naturel et chronologique) et extrinsèque (processus induit par l'environnement et notamment les rayons UV). Plusieurs études ont montré que le vieillissement cutané s'accompagne d'une réduction de la densité capillaire au sein du derme et d'une dégradation de plusieurs protéines de la matrice extracellulaire. Cette atteinte morphologique est associée à une diminution de la capacité vasodilatatrice maximale de la microcirculation dermique et en particulier, de la réponse maximale du flux sanguin cutané à un échauffement local de la surface cutanée à des températures avoisinant les 43-44°C. Cette réponse, appelée hyperémie locale induite par la chaleur (local thermal hyperemia), est facilement mesurable par des investigations non invasives, telles que le laser Doppler. Nous avons entrepris cette étude afin d'investiguer les effets de l'âge sur la réactivité de la microcirculation dermique dans des zones cutanées exposées différemment aux rayons UV. Pour ce faire, nous avons étudié, chez des patients jeunes (18 à 30 ans, n=13) et des patients âgés (> 60 ans, n=13), la vasodilatation cutanée induite par réchauffement local de la peau, au niveau de 3 sites anatomiques différents (la cuisse, l'avant- bras et le front). Les mesures ont été effectuées au moyen d'un laser Doppler. Pour chaque sujet et chaque site, la température cutanée fut tout d'abord amenée à 34°C par 2 corps de chauffe (A et B), disposés de manière adjacente sur la peau. La température fut ensuite augmentée à 39°C (corps de chauffe A) et à 41°C (corps de chauffe B) pour une durée de 30 minutes, dans l'optique d'induire une vasodilatation sous- maximale. Ensuite, la température fut augmentée à 43 °C (corps de chauffe A et B) pour 15 minutes supplémentaires. Enfin, la vasodilatation maximale a été induite par un échauffement local à 44°C pour 15 minutes supplémentaires (corps de chauffe A et B). L'enregistrement séquentiel du flux sanguin cutané, effectué chaque minute par laser Doppler imager, donne des images sur lesquelles peut être calculé le flux sanguin cutané (unités de perfusion, PU). Par la suite, nous avons calculé les conductances vasculaires cutanées (CVC), en divisant le flux sanguin (PU) par la tension artérielle moyenne (mmHg), afin de permettre une normalisation entre les différents sujets. Les CVC, évaluées au temps de départ (température 34°C) et après vasodilatation maximale (température 44°C), étaient plus hautes au niveau du front qu'au niveau des 2 autres sites anatomiques. Sur les 3 sites, la CVC maximale (température 44°C) diminuait avec l'âge mais de façon moins importante au niveau du front, en comparaison avec les 2 autres sites. La réponse aux températures sous-maximales (température 39 et 41°C), exprimée en pourcentage de la CVC maximale, ne variait pas avec l'âge ni en fonction du site anatomique étudié. En conclusion, cette étude est la première à étudier simultanément l'hyperémie locale induite par la chaleur sur 3 sites ayant une exposition différente aux rayons UV. Le processus utilisé (laser Doppler imager) est également unique dans la littérature concernant les altérations de la microcirculation cutanée en lien avec l'âge. Cette étude confirme ainsi que le vieillissement cutané intrinsèque et/ou extrinsèque réduit la capacité vasodilatatrice maximale de la microcirculation dermique. Par contre, la réactivité à réchauffement local à des températures moindres ne semble pas être affectée.

BAY 41-2272 activates host defence against local and disseminated Candida albicans infections

In our previous study, we have found that 5-cyclopropyl-2-[1-(2-fluoro-benzyl)-1H-pyrazolo[3,4-b]pyridine-3-yl]-pyrimidin-4-ylamine (BAY 41-2272), a guanylate cyclase agonist, activates human monocytes and the THP-1 cell line to produce the superoxide anion, increasing in vitro microbicidal activity, suggesting that this drug can be used to modulate immune functioning in primary immunodeficiency patients. In the present work, we investigated the potential of the in vivo administration of BAY 41-2272 for the treatment of Candida albicans and Staphylococcus aureus infections introduced via intraperitoneal and subcutaneous inoculation. We found that intraperitoneal treatment with BAY 41-2272 markedly increased macrophage-dependent cell influx to the peritoneum in addition to macrophage functions, such as spreading, zymosan particle phagocytosis and nitric oxide and phorbol myristate acetate-stimulated hydrogen peroxide production. Treatment with BAY 41-2272 was highly effective in reducing the death rate due to intraperitoneal inoculation of C. albicans, but not S. aureus. However, we found that in vitro stimulation of peritoneal macrophages with BAY 41-2272 markedly increased microbicidal activities against both pathogens. Our results show that the prevention of death by the treatment of C. albicans-infected mice with BAY 41-2272 might occur primarily by the modulation of the host immune response through macrophage activation.
