Serum midkine is a more sensitive predictor for hepatocellular carcinoma than Dickkopf-1 and alpha-L-fucosidase in cirrhotic HCV patients.

ABSTRACT: Alpha fetoprotein (AFP) level is the gold standard diagnostic tool for detection and monitoring hepatocellular carcinoma (HCC) but with low sensitivity. Thus, the identification of alternative or combined serum markers of HCC is highly needed. Therefore, the aim of this work was to verify the value of serum midkine (MDK), Dickkopf-related protein 1 (DKK1), and alpha-L-fucosidase (AFU) in detection of HCC.We recruited 244 subjects to the present study; 89 with liver cirrhosis, 86 cirrhotic hepatitis C virus (HCV) induced HCC, and 69 apparently healthy volunteers as controls. Serum AFP, MDK, DKK1, and AFU were measured by ELISA.Patients with HCC showed significantly higher serum MDK, DKK1, and AFU levels compared with those patients with liver cirrhosis and healthy controls (X2 = 179.56, 153.94, and 90.07 respectively) (P < .001 in all). In HCC cases, neither of MDK, DKK1, or AFU was correlated with tumor number. On the other hand, only serum DKK1 was significantly higher in lesions >5 cm, those with portal vein thrombosis and advanced HCC stage. Receiver operator characteristic (ROC) curve analysis showed that serum MDK levels discriminated between cirrhosis and HCC at a sensitivity of 100%, a specificity of 90% at cut-off value of >5.1 ng/mL.Although our results showed that serum MDK, DKK-1, and AFU are increased in HCC cases only MDK may be considered as the most promising serological marker for the prediction of the development of HCC in cirrhotic HCV patients.

Molecular Patterns of MEFV Gene Mutations in Egyptian Patients with Familial Mediterranean Fever: A Retrospective Cohort Study.

BACKGROUND: Familial Mediterranean Fever (FMF) is a hereditary autosomal recessive disease which is mainly seen in the Turks, Armenians, Arabs, and Jews. It is characterized by recurrent episodes of fever, polyserositis, and rash. MEFV gene, encoding pyrin protein, is located on the short arm of chromosome 16. FMF is associated with a broad mutational spectrum in this gene. Certain mutations are more common in particular ethnic groups. To date, different mutations of MEFV were observed in studies carried out in different regions worldwide. However, most of these studies did not extensively investigate the Egyptian population, in spite of the high prevalence of FMF in this geographical region. AIM: To identify the frequency of MEFV gene mutations among the patients who presented with FMF like symptoms and, to characterize the different genetic mutations and their association with increased Amyloid A among Egyptian patients. METHODS: FMF Strip Assay (Vienna Lab Diagnostics, Vienna, Austria) was used. This test is based on reverse hybridization of biotinylated PCR products on immobilized oligonucleotides for mutations and controls in a parallel array of allele-specific oligonucleotides. RESULTS: Among the 1387 patients presenting with signs and symptoms suggestive of FMF, 793 (57.2%) were of undefined mutations, whereas 594 had MEFV gene mutations. 363 patients (26.2%) were heterozygous mutants, 175 patients (12.6%) were compound heterozygous mutants, and 56 patients (4%) were homozygous mutants. The most commonly encountered gene mutations in heterozygous and homozygous groups were E148Q (38.6%), M694I (18.1%), and V726A (15.8%). The most commonly encountered gene mutations in the compound heterozygous groups were E148Q+M694I observed in 20.6% of the patients, followed by M694I+V726A and M6801+V726A found in 18.9% and 11.4 %, respectively. The most commonly encountered gene mutation associated with abdominal pain, fever, and high serum Amyloid A was E148Q allele (37.5%). CONCLUSIONS: Unlike all previous publications, E148Q allele was found to be the most frequent in the studied patients. Moreover, this allele was associated with increased Amyloid A. 793 patients were free of the 12 studied Mediterranean mutations, which implies the necessity to perform future sequencing studies to reveal other mutations.

Coagulation abnormalities in type 1 Gaucher disease in children.

Gaucher disease is the most prevalent inherited lysosomal storage disorder caused by deficiency of beta-glucocerebrosidase enzyme. Clinically, 3 forms of Gaucher disease are recognized, of which type 1 is the mild to moderately severe, slowly progressive, nonneuropathic form. Bleeding disorders in Gaucher disease are believed to be due to thrombocytopenia but there may be additional factors that influence coagulation and fibrinolysis in Gaucher disease patients. The aim of the present work was to study some coagulation parameters in the Egyptian children with type 1 Gaucher disease. Five newly diagnosed patients and another 5 patients on enzyme replacement therapy (ERT) were enrolled in the study. Their coagulation profile, including coagulation factors, was evaluated. The results showed that in newly diagnosed cases factors II and VII were deficient in 40%, factor V was deficient in 20%, and all the cases had low levels of serum fibrinogen. In patients on ERT, factors VII and VIII were deficient in 60%, factor XI was deficient in 40% and factors V, X, and XII were deficient in 20% of cases. In conclusion, Egyptian patients with type 1 Gaucher disease, whether newly diagnosed or receiving enzyme replacement therapy, experience coagulation factor abnormalities regardless the clinical expression of bleeding diathesis. This should be taken into consideration before these patients are subjected to surgery for, e.g., splenectomy, which is common in these patients.
