IL-10 and IL-12p40 in Egyptian patients with HCV-related chronic liver disease

Hepatitis C virus (HCV) is the leading cause of chronic liver disease worldwide with a prevalence of approximately 14% in Egypt. IL-10 is a cytokine produced by Th2 cells. It down-regulates the proinflammatory response and modulates hepatic fibrogenesis. IL-12 is produced by antigen presenting cells. It promotes Th1 cell response and has many antiviral properties. Data concerning the Th-1/Th-2 balance in chronic hepatitis C (CH-C) are rather conflicting. Using ELISA, we assessed serum IL-10 and IL-12p40 levels in 66 Egyptian patients with HCV-related liver illness (CH-C, cirrhosis, and HCC), and their relationship to disease activity. Our results showed that spontaneous IL-10 was undetectable in patients with CH-C, HCC or controls. Only 5/22 (23%) of patients with cirrhosis showed detectable levels of IL-10. IL-12p40 was elevated in the patient groups compared to controls (p= 0.01, p= 0.01, p= 0.05 in CH-C, cirrhosis and HCC, respectively). The presence of IL-12p40 was associated with HCV level of viremia and serum AST. Serum ALT level was significantly associated with the level of IL-12p40. IL-12p40 was unrelated to liver histology or fibrosis. We concluded that in the Egyptian patients an augmentation of IL-12p40 and a suppression of IL-10 are both found. Whether this pattern is related to HCV genotype 4, or to the presence of schistosomiasis would need to be further investigated.     

Effects of Enteral Nutrition on the Barrier Function of the Intestinal Mucosa and Dopamine Receptor Expression in Rats With Traumatic Brain Injury

Background: Impaired intestinal mucosal barrier (IMB) function is common in traumatic brain injury (TBI), but dopamine receptors (DRs) change in intestinal mucosa after TBI, and effects of enteral nutrition (EN) and supplements on IMB function remain unclear. Our purpose was to study the effects of EN and supplements on intestinal mucosal permeability (IMPB) and the expression of DRs DRD1 and DRD2 in the intestinal mucosa of rats with TBI. Methods: Forty‐eight rats were divided into 8 groups; control, animals with TBI, dopamine group, animals with TBI treated with dopamine antagonist, EN alone, or EN combined with glutamine, probiotics, or a combination of probiotics and glutamine daily after TBI. Results: The IMPB was improved in the glutamine, probiotics, and combination groups. Including probiotics improved IMPB more than adding glutamine, and bacterial translocation in the intestines after TBI was reduced in the probiotics and combination groups (all Ps < .01). TBI led to elevated DRD1 and DRD2 mRNA and protein levels, which were reduced in the DA antagonist, glutamine, probiotics, and combination groups. DRD2 mRNA and protein levels in the probiotics and combination groups were decreased more than in the DA antagonist group (all Ps < .01). The increased IMPB after TBI correlated with increased DRD1 and DRD2 levels in the rat intestinal mucosa. Conclusion: EN supplemented with probiotics or combining glutamine and probiotics lowers the increased IMPB, bacterial translocation, and DRD1 and DRD2 mRNA and protein expression in rat intestinal mucosa caused by TBI.     

Normal outcome of pregnancy in chronic myeloid leukemia treated with interferon-alpha in 1st trimester: report of 3 cases and review of the literature

Three patients with chronic myeloid leukemia (CML) in chronic phase received interferon-alpha during pregnancy, starting from the 1st trimester. No maternal complications were reported. The 3 patients delivered normal looking babies apart from one baby who was found to have transient mild thrombocytopenia. Subsequently these children were followed for 30, 12, and 4 months and all had normal growth and development.     

Latent tuberculosis infection: risks to health care students at a hospital in Lima, Peru.

SETTING: University hospital and university campus in Lima, Peru. OBJECTIVE: To demonstrate the risk of latent tuberculosis infection (LTBI) in the hospital relative to the community. DESIGN: Prospective cohort study of university students measuring prevalence, boosting, and conversion of tuberculin skin tests (TSTs) among health care students (HCS) and non-health care students (NHCS). RESULTS: Among the HCS relative to NHCS, prevalence of initial positive TST was 20.9% vs. 12.2% (P < 0.001), and conversion rate was 1.1% vs. 0% (P = 0.423) at the 10 mm cut-off and 11.8% vs. 0% at the 6 mm cut-off (P = 0.00005). Multivariate analysis showed that the HCS group had a higher risk of baseline positive TST compared with the NHCS group after controlling for confounding factors (OR 1.7, 95% CI 1.1-2.6). CONCLUSION: HCS are at greater risk than NHCS for having positive baseline TSTs and for TST conversion at the 6 mm cut-off. We conclude that the hospital we studied in Lima, Peru, poses a greater risk than the surrounding community for tuberculosis infection, and greater attention to hospital infection control measures is warranted. A higher rate of skin test boosting among the HCS cohort suggests the possibility of transient, non-progressive LTBI, which merits further study.     

Effect of shared care on blood pressure in patients with chronic kidney disease: a cluster randomised controlled trial

Background

Chronic kidney disease (CKD) is highly prevalent in patients with diabetes or hypertension in primary care. A shared care model could improve quality of care in these patients

Aim

To assess the effect of a shared care model in managing patients with CKD who also have diabetes or hypertension.

Design and setting

A cluster randomised controlled trial in nine general practices in The Netherlands.

Method

Five practices were allocated to the shared care model and four practices to usual care for 1 year. Primary outcome was the achievement of blood pressure targets (130/80 mmHg) and lowering of blood pressure in patients with diabetes mellitus or hypertension and an estimated glomerular filtration rate (eGFR)<60ml/min/1.73m².

Results

Data of 90 intervention and 74 control patients could be analysed. Blood pressure in the intervention group decreased with 8.1 (95% CI = 4.8 to 11.3)/1.1 (95% CI = −1.0 to 3.2) compared to −0.2 (95% CI = −3.8 to 3.3)/−0.5 (95% CI = −2.9 to 1.8) in the control group. Use of lipid-lowering drugs, angiotensin-system inhibitors and vitamin D was higher in the intervention group than in the control group (73% versus 51%, 81% versus 64%, and 15% versus 1%, respectively, [P = 0.004, P = 0.01, and P = 0.002]).

Conclusion

A shared care model between GP, nurse practitioner and nephrologist is beneficial in reducing systolic blood pressure in patients with CKD in primary care.
