Role of Climate Change in Changing Hepatic Health Maps.

PURPOSE OF REVIEW: Climate change (CC) is currently responsible for global weather extremes. These weather extremes could contribute to changes in the pattern of health problems. The purpose of this review is to discuss the role of CC on remapping of hepatic diseases and the mechanisms of re-mapping. RECENT FINDINGS: CC was found to have a major influence on the distribution and severity of hepatic diseases, such as outbreaks of vector-borne, water or food-borne, parasitic diseases, re-emerging of disappeared diseases, or emerging of new forms of infectious agents. Migration of infected people from endemic areas due to the CC disasters results in rapid dissemination of infectious diseases that leads to outbreaks or endemicity of diseases in new areas. CC could cause increasing chemical emissions, or change in its biodegradability, or restriction in its dispersion, such as PM, PAHs, heavy metals, mycotoxins, and aquatic toxins. Increase in the concentrations of these chemicals may have significant impacts in changing the health map of hepatic toxicity and liver cancer. The current review confirms the role of CC in changing the pattern of several liver health problems and remapping of these problems in several regions of the world. This review could be of high importance to the health decision-makers as an early alarm and prediction of hepatic health problems with the projected CC.

Effect of surveillance for hepatocellular carcinoma on tumor staging and treatment decisions in Egyptian patients.

PURPOSE: Egyptian hepatocellular carcinoma (HCC) patients present at advanced stages. We aimed to study the influence of surveillance versus non-surveillance on HCC staging and the potential therapeutic options. METHODS: A retrospective study to evaluate the effect of surveillance on early detection of HCC among cirrhotic patients from 2003 to 2008. Patients examined every 6 months using ultrasound and α-fetoprotein (α-FP) (group A) and those diagnosed with those that present for the first time symptomatically or incidentally (group B). Groups were compared for α-FP level, tumour characteristics, severity of liver disease; tumour staging was evaluated by Okuda, CLIP and BCLC staging systems, in addition to the potential therapeutic options. RESULTS: Group A comprised 122 HCC cases and group B 473. Surveillance improved HCC detection: at the stage of single nodule in 62.3% in group A versus 52.2% in group B, (P = 0.046) and reduced the percentage of HCC with portal vein thrombosis in 16.4 versus 33.8%, (P = 0.000) and the percentage of α-FP >400 ng/ml in 19.5 versus 32.6%, (P = 0.006) in groups A and B, respectively. Surveillance doubled the detection of HCC at early stage of BCLC (25.4 vs. 11.9% P = 0.000) and doubled the patients' chance for loco-regional ablation (12.3 vs. 5.9%, P = 0.015) and liver transplantation (10.7 vs. 3.2%, P = 0.001) in groups A and B, respectively. CONCLUSION: HCC surveillance increases early detection of HCC and doubled the chances for curative options. Implementation of both HCC surveillance and cadaveric liver transplantation programs should be recommended in Egypt.
