Prevalence of and factors associated with placental malaria in the White Nile State: a cross-sectional study.

INTRODUCTION: Malaria during pregnancy can lead to maternal and perinatal adverse effects. Despite the preventive measures, recent research has shown that malaria during pregnancy is still a threatening health problem, especially in Sub-Saharan African countries. The current study was conducted to determine the prevalence of and factors associated with placental malaria in Rabak Hospital in central Sudan. METHODOLOGY: A cross-sectional study was conducted from September to October 2021. Pregnant women who delivered at the Rabak Maternity Hospital in Central Sudan were included. A questionnaire was used to gather both obstetric and socio-demographic information. Blood films for malaria were prepared using the maternal, placental, and cord blood, and a placental histology was performed. A logistic regression analysis was performed. RESULTS: For the 208 women, the medians (interquartile range) of their age and parity were 25 (21.0 ‒30.0) years and 2 (1‒4), respectively. Twenty-five (12.0%) of the women had used insecticide-treated nets. Active infection, active-chronic infection, and past-chronic infection were detected in four (1.9%), five (2.4%), and 35 (16.8%) placentas, respectively. One hundred and sixty-four (78.8%) placentas showed no signs of infection. Logistic regression analysis showed that none of the examined factors (age, parity, education, antenatal care level, use of insecticide-treated nets, and blood group) was associated with placental malaria. CONCLUSIONS: Malaria affects 20% of pregnant women, regardless of their age and parity. Preventative measures should therefore be encouraged in this area.

Challenges in diagnosis and management of invasive ductal carcinoma in axillary ectopic breast tissue: a case study.

Ectopic breast tissue (EBT) is breast tissue located outside the normal anatomic boundaries of the breasts, developing due to incomplete embryological regression of the mammary ridges. EBT can develop anywhere along the milk line, with the axilla being the most common site. While generally benign, EBT can undergo malignant transformation. This case report discusses a 24-year-old female with locally advanced invasive ductal carcinoma in the axillary EBT, highlighting its clinical presentation, diagnostic process, and management in a resource-limited setting. The patient underwent wide local excision and axillary lymph node dissection followed by adjuvant chemotherapy and radiotherapy, achieving a favorable short-term outcome. This case underscores the importance of considering EBT in differential diagnosis of axillary masses and the need for tailored treatment strategies in such settings.

The missing link between cancer stem cells and immunotherapy.

Cancer stem cells (CSCs) are cancer cells that can self-renew and give rise to tumors. The multipotency of CSCs enables the generation of diverse cancer cell types and their potential for differentiation and resilience against chemotherapy and radiation. Additionally, specific biomarkers have been identified for them, such as CD24, CD34, CD44, CD47, CD90, and CD133. The CSC model suggests that a subset of CSCs within tumors is responsible for tumor growth. The tumor microenvironment (TME), including fibroblasts, immune cells, adipocytes, endothelial cells, neuroendocrine (NE) cells, extracellular matrix (ECM), and extracellular vesicles, has a part in shielding CSCs from the host immune response as well as protecting them against anticancer drugs. The regulation of cancer stem cell plasticity by cancer-associated fibroblasts (CAFs) occurs through specific signaling pathways that differ among various types of cancer, utilizing the IGF-II/IGF1R, FAK, and c-Met/FRA1/HEY1 signaling pathways. Due to the intricate dynamics of CSC proliferation, controlling their growth necessitates innovative approaches and much more research. Our current review speculates an outline of how the TME safeguards stem cells, their interaction with CSCs, and the involvement of the immune and inflammatory systems in CSC differentiation and maintenance. Several technologies have the ability to identify CSCs; however, each approach has limitations. We discuss how these methods can aid in recognizing CSCs in several cancer types, comprising brain, breast, liver, stomach, and colon cancer. Furthermore, we explore different immunotherapeutic strategies targeting CSCs, including stimulating cancer-specific T cells, modifying immunosuppressive TMEs, and antibody-mediated therapy targeting CSC markers.

Challenging the Urologist of the Future: Time for a Change?

Physicians need both medical expertise and diverse skills for effective patient care. Adaptability is also key in embracing advances in technology and new techniques. We outline six thought-provoking points to guide the new generation of urologists.

Can brucellosis influence the course of chronic hepatitis C in dual infection?

Hepatitis C and brucellosis are infectious diseases that occur worldwide, and both are endemic in Egypt. Co-infection with both agents is possible, and this can involve the liver in various ways. In this study, we investigated serum tissue inhibitor metalloproteinase-1 (TIMP-1), viral load, and liver functions in patients co-infected with hepatitis C virus (HCV) before and after brucellosis treatment. Over 3 years, 241 consecutive HCV patients (before interferon therapy was received) with recurrent fever who had occupational contact with animals were tested for brucellosis co-infection by a standard tube agglutination test. In patients with dual infection, viraemia (RT-PCR), TIMP-1 measured by ELISA, and liver functions were assessed and re-evaluated 2 months after brucellosis treatment. The number of patients with HCV/brucellosis co-infection was 32 out of 241 (13.3%). TIMP-1, viraemia, AST, ALT and bilirubin showed significant decrease (improvement) after brucellosis treatment (p < 0.001) but an insignificant difference (p > 0.05) with regard to serum albumin and prothrombin concentration. The study revealed that brucellosis is an important infection in HCV-infected patients and can aggravate the course of disease, suggesting that early treatment and prevention are important.

Molecular and pathological investigation of avian reovirus (ARV) in Egypt with the assessment of the genetic variability of field strains compared to vaccine strains.

Avian orthoreovirus (ARV) is among the important viruses that cause drastic economic losses in the Egyptian poultry industry. Despite regular vaccination of breeder birds, a high prevalence of ARV infection in broilers has been noted in recent years. However, no reports have revealed the genetic and antigenic characteristics of Egyptian field ARV and vaccines used against it. Thus, this study was conducted to detect the molecular nature of emerging ARV strains in broiler chickens suffering from arthritis and tenosynovitis in comparison to vaccine strains. Synovial fluid samples (n = 400) were collected from 40 commercial broiler flocks in the Gharbia governorate, Egypt, and then pooled to obtain 40 samples, which were then used to screen ARV using reverse transcriptase polymerase chain reaction (RT-PCR) with the partial amplification of ARV sigma C gene. The obtained RT-PCR products were then sequenced, and their nucleotide and deduced amino acid sequences were analyzed together with other ARV field and vaccine strains from GenBank. RT-PCR successfully amplified the predicted 940 bp PCR products from all tested samples. The phylogenetic tree revealed that the analyzed ARV strains were clustered into six genotypic clusters and six protein clusters, with high antigenic diversity between the genotypic clusters. Surprisingly, our isolates were genetically different from vaccine strains, which aligned in genotypic cluster I/protein cluster I, while our strains were aligned in genotypic cluster V/protein cluster V. More importantly, our strains were highly divergent from vaccine strains used in Egypt, with 55.09-56.23% diversity. Sequence analysis using BioEdit software revealed high genetic and protein diversity between our isolates and vaccine strains (397/797 nucleotide substitutions and 148-149/265 amino acid substitutions). This high genetic diversity explains the vaccination failure and recurrent circulation of ARV in Egypt. The present data highlight the need to formulate a new effective vaccine from locally isolated ARV strains after a thorough screening of the molecular nature of circulating ARV in Egypt.

Correlation of viral load with bone marrow and hematological changes in pale patients with chronic hepatitis C virus.

Liver is considered the target of hepatitis C virus (HCV), which has marked tropism for hepatocytes. In this study, we investigated changes in bone marrow (BM) and blood and their correlation with viremia level in 30 pale patients with chronic HCV who were selected before antiviral therapy. Patients with BM positive for HCV RNA (53.33 %) showed moderate to high viremia, while patients with BM negative for RNA (46.67 %) had low viremia. There was no significant difference in the liver histopathology between patients with HCV-RNA-negative and positive BM. Patients with BM positive for HCV RNA showed significant changes in BM cells, including the degree of immune complex deposition and alterations in peripheral blood counts compared to patients with BM negative for RNA and healthy controls, suggesting that BM changes could be a sequel or a reservoir for HCV viremia.

Histomorphometric study of placental blood vessels of chorion and chorionic villi vascular area among women with preeclampsia.

INTRODUCTION: The direction of blood movement in normal and abnormal placenta is curious from a morphometric point of view. Once pregnancy is compromised by an illness like hypertension, maternal and foetal distress can lead to negative outcomes. The quantitative variations in the blood vessels within the chorion and the chorionic villi in placentas from pregnancies are complicated by preeclampsia (PE) and are poorly defined. The purpose of this study was to calculate and explore the morphometric measurement of blood vessels involved in the progress of hypertension through pregnancy within the chorion and the chorionic villi among normotensive women (n = 39) versus a preeclamptic group (n = 35). METHODS: Measurements used a computerized morphometry system and a Vascular Medicine Institute (VMI) calculator. RESULTS: Our data showed a significant decrease in vessel area (VA), wall area (WA), lumen area (LA), mean wall thickness-boundary (MWTB), mean wall thickness-rosette (MWTR), mean diameter-rosette (MDR), mean wall thickness-skeleton (MWTS), and external diameter-skeleton (EDS) in preeclampsia women compared to normotensive women. There were no significant differences between preeclampsia and control group in lumen area. DISCUSSION: We concluded that preeclamptic chorion and chorionic villi vessels are linked with significant structural discrepancies; future studies should address morphological events that occur throughout pregnancy including associations between arterial elastic properties-mainly collagen and structural proteins in hypertensive patients. A more integrated approach involving parallel analysis of the effects of potential vasoactive factors on the morphology of foetal vessel alteration is also needed.

Two distinctive types of telocytes in gills of fish: A light, immunohistochemical and ultra-structure study.

Telocytes (TCs) are a vital constituent of interstitial tissue. They contribute to regulating cell function in heterotypic connections via direct contact or paracrine singling. Few studies mentioned intraepithelial TCs; however, they have been identified with scanning electron microscopy (SEM) and transmission electron microscopy (TEM). In this study, we investigated the intraepithelial and interstitial TCs using immunohistochemistry (IHC) and TEM. TCs can be identified by their distinctive telopodes (TPs), which consist of podoms and podomere, using TEM and immunohistochemical staining with CD34, CD117, and VEGF antibodies. Intraepithelial TCs established heterocontact with the lamellar capillary and interstitial TCs connected with the blood vessel in lamina propria. Intraepithelial TCs established direct contact with epithelial cells, which formed the lymph space while interstitial TCs connected with the secondary vascular vessels. The study provides evidence for TCs' heterocontact with lamellar blood capillaries, the blood vessels, chloride cells, and immune cells, such as rodlet cells and lymphocytes. In conclusion, TCs have a role in regulating respiratory activities, maintaining osmotic pressure, modulating the immune response, and conducting immunosurveillance. RESEARCH HIGHLIGHTS: We investigated the intraepithelial and interstitial TCs using immunohistochemistry (IHC) and TEM. TCs can be identified by their distinctive telopodes (TPs), which consist of podoms and podomere, using TEM and immunohistochemical staining with CD34, CD117, and VEGF antibodies. Intraepithelial TCs established heterocontact with the lamellar capillary and interstitial TCs connected with the blood vessel in lamina propria.

Treatment of Hepatitis C Cirrhotic Patients With Directly Acting Antivirals: A Multicenter Study.

BACKGROUND: With the introduction of sofosbuvir-based regimens, high cure rates and decreased duration has been achieved. Several studies showed variances in SVR rates between different genotypes, with lower rates of SVR among cirrhotic patients. The aim of our study was to assess the safety and effectiveness of sofosbuvir-based antiviral regimens for the treatment of HCVinfected Egyptian cirrhotic patients. METHODS: This was a retrospective, observational, and comparative study. A total of nine hundred and forty-six cirrhotic patients with chronic HCV genotype 4 infection, who were eligible for direct acting drugs (DAAs) therapy, were enrolled. The primary outcome measures were the number of patients with successful eradication of the virus evidenced by SVR at 12 weeks after discontinuation of therapy (SVR12), and the secondary outcome measures were the incidence of adverse effects associated with the tested HCV therapy. RESULTS: Among the 946 patients enrolled in the study, 527 patients (55.7%) were males and 419 patients (44.3%) were females with a mean age of 54.00±8.88 years. 20.2% were diabetics and 19.1% were hypertensive. Patients were classified according to Child-Pugh classifications; 818 patients (86.46%) were Child-Pugh class A cirrhosis, while 28 patients (13.53%) were Child-Pugh class B cirrhosis. The SVR12 rate was 96.93% (917 /946). Treatment response in the Child-Pugh class A cirrhosis was 794 (97%) after 12 weeks, while treatment response in the Child-Pugh class B cirrhosis was 123 (96%). Mild side effects were observed in 76 patients. CONCLUSIONS: Sofosbuvir based regimens were effective and safe in the treatment of cirrhotic patients with chronic hepatitis C genotype 4.

HCV and HEV: two players in an Egyptian village, a study of prevalence, incidence, and co-infection.

The highest recorded hepatitis C virus (HCV) prevalence worldwide is in Egypt. A high prevalence of hepatitis E virus (HEV) in chronic liver disease has been reported. The aim of this study was to study prevalence, incidence, and outcome of HCV infection in an Egyptian Nile Delta village and the relation between HEV infection and HCV-related chronic hepatic affection. This prospective cohort study included 2085 Nagreej village residents. Mass HCV screening was conducted and testing for HEV antibodies among HCV-infected patients performed. The annual incidence of HCV was recorded. Five hundred five (24.22%) of the tested villagers were positive for HCV RNA. Prevalence escalated with age and male sex. The main recorded risk factors were a history of surgery, dental procedures, hospitalization, blood transfusion, and antischistosomal treatment. HEV IgG antibody was positive in 71.4% of individuals with chronic HCV and 96.1% with advanced liver disease (cirrhosis ± hepatocellular carcinoma (HCC)). After 1 year, 29 of the 1390 HCV Ab negative villagers had a positive HCV PCR, placing an annual incidence of new HCV infections at 2.09%. The Egyptian HCV prevalence remains high with infection particularly among the elderly. The annual incidence in a small Nile Delta village is 2.086%. HCV-HEV co-infection may lead to a worse prognosis among Egyptians with chronic liver disease.

Placental growth factor, vascular endothelial growth factor, and hypoxia-inducible factor-1α in the placentas of women with pre-eclampsia.

BACKGROUND: Although the exact mechanism of pre-eclampsia - high blood pressure and proteinuria after 20 gestational weeks - is not yet fully understood, placental growth factor (PLGF), vascular endothelial growth factor (VEGF), and hypoxia-inducible factor (HIF) are known to play important roles in vascularization and in the pathology of pre-eclampsia. METHODS: PLGF, VEGF, and HIF-1α were evaluated by immunohistochemistry in the placentas of Sudanese women with mild or severe pre-eclampsia, and in normal controls. RESULTS: Sixty-two women had severe pre-eclampsia, 102 had mild pre-eclampsia and 101 women served as healthy controls. Immunohistochemical staining of PLGF was significantly lower in placentas of women with severe pre-eclampsia (16%) compared with those with mild pre-eclampsia (8.8%) and placentas of normotensive women (40.6%; p < .001). Significantly more of the pre-eclamptic placentas expressed VEGF: in 32%, 17.6%, and 14.9% (p = .020) of the placentas of women with severe or mild pre-eclampsia and in controls, respectively. Significantly more of the pre-eclamptic placentas expressed HIF-1α: in 15%, 10.8%, and 5.0% of the placentas of women with severe or mild pre-eclampsia, and in controls, respectively (p = .044). CONCLUSION: The current study showed that PLGF, VEGF, and HIF-1α are involved in the pathophysiology of pre-eclampsia.

Helicobacter pylori may be an initiating factor in newly diagnosed ulcerative colitis patients: A pilot study.

AIM: To directly visualize Helicobacter pylori (H. pylori) by the highly sensitive and specific technique of immunohistochemical staining in colonic tissue from patients newly diagnosed with ulcerative colitis (UC). METHODS: Colonoscopic biopsies from thirty patients with newly diagnosed UC and thirty controls were stained with Giemsa stain and immunohistochemical stain for detection of H. pylori in the colonic tissue. Results were confirmed by testing H. pylori Ag in the stool then infected patients were randomized to receive either anti H. pylori treatment or placebo. RESULTS: Twelve/30 (40%) of the UC patients were positive for H. pylori by Giemsa, and 17/30 (56.6%) by immunohistochemistry stain. Among the control group 4/30 (13.3%) and 6/30 (20 %) were positive for H. pylori by Giemsa and immunohistochemistry staining respectively. H. pylori was significantly higher in UC than in controls (P = 0.04 and 0.007). All Giemsa positive patients and controls were positive by immunohistochemical stain. Four cases of the control group positive for H. pylori also showed microscopic features consistent with early UC. CONCLUSION: H. pylori can be detected in colonic mucosa of patients with UC and patients with histological superficial ulcerations and mild infiltration consistent with early UC. There seems to be an association between UC and presence of H. pylori in the colonic tissue. Whether this is a causal relationship or not remains to be discovered.

Blood Ammonia Level Correlates with Severity of Cirrhotic Portal Hypertensive Gastropathy.

BACKGROUND: Portal hypertensive gastropathy (PHG) is a common anomaly with potential for bleeding found in portal hypertension. Blood ammonia levels correlate well with liver disease severity and existence of portosystemic shunts. Increased ammonia results in vasodilation and hepatic stellate cell activation causing and exacerbating portal hypertension. OBJECTIVE: To assess the relation of blood ammonia to the presence and severity of portal hypertensive gastropathy in cirrhosis. METHODS: This cross-sectional study included 381 cirrhotics undergoing screening for esophageal varices (EV) divided into a portal hypertensive gastropathy group (203 patients with EV and PHG), esophageal varix group (41 patients with EV but no PHG), and control group (137 patients with no EV or PHG). A full clinical examination, routine laboratory tests, abdominal ultrasonography, child score calculation, and blood ammonia measurement were performed for all patients. RESULTS: Blood ammonia, portal vein, splenic vein, and splenic longitudinal diameters were significantly higher and platelet counts lower in patients with EV and EV with PHG than controls. Patients having EV with PHG had significantly higher bilirubin and ammonia than those with EV but no PHG. Severe PHG was associated with significantly higher ammonia, EV grades, and superior location and a lower splenic longitudinal diameter than mild PHG. The PHG score showed a positive correlation with blood ammonia and a negative correlation with splenic longitudinal diameter. CONCLUSIONS: Blood ammonia levels correlate with the presence, severity, and score of portal hypertensive gastropathy in cirrhosis suggesting a causal relationship and encouraging trials of ammonia-lowering treatments for the management of severe PHG with a tendency to bleed.

Pilot study of orphenadrine as a novel treatment for muscle cramps in patients with liver cirrhosis.

BACKGROUND AND AIMS: Muscle cramps markedly affect the quality of life in cirrhotic patients with no available highly effective treatment. The aim of this study was to assess the safety and efficacy of orphenadrine in the treatment of muscle cramps in cirrhotic patients. METHODS: The study enrolled 30 liver cirrhosis patients complaining of frequent muscle cramps (≥3 per week), who were randomized to receive either orphenadrine 100 mg or calcium carbonate 500 mg twice daily as a control for one month. Severity, frequency, and duration of the muscle cramps were assessed before and after treatment as well as recurrence after washout of the drug for two weeks. Side effects were recorded. RESULTS: One month after treatment with orphenadrine; the frequency of muscle cramps decreased significantly to 0.6 ± 0.74 per week compared to 12.53 ± 6.01 at baseline (p < 0.001), the duration of muscle cramps decreased from 1 min to 0.1 min after treatment (p < 0.001). The pain score improved significantly from a score of 8/10 to 0/10 (p < 0.001). The side effects were few, such as dry mouth, drowsiness, and nausea, with no significant difference between their occurrences in the two groups. CONCLUSION: Orphenadrine is safe and effective in treatment of muscle cramps in patients with liver cirrhosis.

Randomized-controlled trial of rifaximin versus norfloxacin for secondary prophylaxis of spontaneous bacterial peritonitis.

BACKGROUND AND AIMS: Spontaneous bacterial peritonitis (SBP) is a serious complication of liver cirrhosis with a high recurrence rate and a marked increase in mortality. Norfloxacin is used widely for the secondary prophylaxis of SBP; however, its extensive long-term use has led to an increase in the incidence of quinolone-resistant and Gram-positive SBP. Rifaximin is a nonabsorbable broad-spectrum antibiotic and does not appear to promote emergence of resistance. The aim of this study was to compare the safety and efficacy of rifaximin versus norfloxacin for the secondary prevention of SBP in patients with liver cirrhosis and ascites. MATERIALS AND METHODS: Two hundred and sixty two cirrhotic patients with ascites and a previous episode of SBP were assigned randomly to receive either 1200 mg rifaximin or 400 mg of norfloxacin daily for 6 months. All patients were monitored clinically each month and with ascitic fluid examination at the end of 2 and 6 months if not clinically suspected of recurrence earlier. RESULTS: Recurrence of SBP was significantly lower in the rifaximin group (3.88 vs. 14.13%) compared with the norfloxacin group (P=0.04). The mortality rate was significantly decreased in the rifaximin group (13.74 vs. 24.43%) compared with the norfloxacin group (P=0.044). The causes of death between the two groups did not show a significant difference (P=0.377), but encephalopathy-related deaths were three folds higher in the norfloxacin group. There was a significant decrease in the side effects in the rifaximin group versus the norfloxacin group (P=0.033). CONCLUSION: Rifaximin was more effective than norfloxacin in the secondary prevention of SBP. Encephalopathy-related mortality and side effects were fewer in the rifaximin group.

Randomized placebo-controlled study of baclofen in the treatment of muscle cramps in patients with liver cirrhosis.

BACKGROUND AND AIMS: Muscle cramps adversely influence the quality of life of patients with liver cirrhosis. Indeed, to date, a well-established therapy for this complication is still lacking. This is the first randomized placebo-controlled trial of baclofen in the treatment of muscle cramps in patients with liver cirrhosis. PATIENTS AND METHODS: A total of 100 patients with liver cirrhosis and muscle cramps signed an informed consent to participate in this study. They were recruited from the Department of Tropical Medicine-Tanta University Hospital. They were randomized to receive either baclofen or placebo for 3 months. Patients were followed monthly and 1 month after withdrawal. At each visit, the clinicoepidemiological data were recorded, the muscle cramp questionnaire was filled, and any drug-related side effects were reported. RESULTS: In the baclofen group, the frequency of muscle cramps decreased significantly after 1 and 3 months of treatment (P<0.005), with a significant relapse after withdrawal (P<0.001). Patients receiving baclofen showed a significant decrease in the severity and duration of muscle cramps (P<0.001). After 3 months of baclofen therapy at a dose of 30 mg/day, muscle cramps disappeared completely in 72%, reduced in 20%, and led to no change in 8% of patients. No significant changes in the frequency, severity, and duration of muscle cramps were noted in the placebo group. There were few but nonsignificant side effects in the baclofen group compared with the placebo group. CONCLUSION: Baclofen was well tolerated, safe, and effective in the treatment of muscle cramps in patients with liver cirrhosis.

Randomized controlled study of endoscopic band ligation and argon plasma coagulation in the treatment of gastric antral and fundal vascular ectasia.

BACKGROUND: Gastric antral vascular ectasia (GAVE) is characterized by mucosal and submucosal vascular ectasia causing recurrent hemorrhage and thus, chronic anemia, in patients with cirrhosis. Treatment with argon plasma coagulation (APC) is an effective and safe method, but requires multiple sessions of endoscopic therapy. Endoscopic band ligation (EBL) was found to be a good alternative for APC as a treatment for GAVE, especially in refractory cases. The aim of this prospective randomized controlled study was to evaluate the safety and efficacy of EBL, as compared to APC, in the treatment of GAVE and gastric fundal vascular ectasia (GFVE). PATIENTS AND METHODS: A total of 88 cirrhotic patients with GAVE were prospectively randomized to endoscopic treatment with either EBL or APC, every 2 weeks until complete obliteration was accomplished; then they were followed up endoscopically after 6 months, plus they had monthly measurement of hemoglobin levels during that period. RESULTS: We describe the presence of mucosal and submucosal lesions in the gastric fundal area that were similar to those found in GAVE in 13 patients (29.5%) of the EBL group and 9 patients (20.5%) of the APC group; we named this GFVE. In these cases, we treated the fundal lesions with the same techniques we had used for treating GAVE, according to the randomization. We found that EBL significantly decreased the number of sessions required for complete obliteration of the lesions (2.98 sessions compared to 3.48 sessions in the APC group (p < 0.05)). Hemoglobin levels increased significantly after obliteration of the lesions in both groups, compared to pretreatment values (p < 0.05), but with no significant difference between the two groups (p > 0.05); however, the EBL group of patients required a significantly smaller number of units of blood transfusion than the APC group of patients (p < 0.05). There were no significant differences in adverse events nor complications between the two groups (p > 0.05). CONCLUSIONS: This study described and histologically proved the presence of GFVE occurring comcomitantly with GAVE in cirrhotic patients. We showed that GFVE can be successfully managed by EBL or APC. Our study revealed that EBL is more effective and is comparable in safety to APC, in the treatment of GAVE and GFVE in cirrhotic patients.

A 2-week Nitazoxanide-based quadruple treatment as a rescue therapy for Helicobacter pylori eradication: A single center experience.

As there are increasing reports of fluoroquinolone resistance on use as a first- or second-line treatment for Helicobacter pylori (H pylori), we aimed at evaluation of the efficacy and safety of nitazoxanide-based regimen as a rescue regimen in Egyptian patients whose previous traditional treatment for H pylori infection failed.In total, 100 patients from the outpatient clinic of the Tropical medicine department, Tanta University hospital in whom the standard triple therapy (clarithromycin-based triple therapy) failed were enrolled in the study. Nitazoxanide (500 mg bid), levofloxacin (500 mg once daily), omeprazole (40 mg bid), and doxycyclin (100 mg twice daily) were prescribed for 14 days. Eradication was confirmed by stool antigen for H pylori 6 weeks after the end of treatment. Among the patients enrolled in the study, 44% of patients were men and the mean age for the participants in the study was 46.41 ±â€Š8.05, 13% of patients were smokers, and 4% of patients had a previous history of upper gastro-intestinal bleeding. A total of 94 patients (94%) completed the study with excellent compliance. Only 1 patient (1%) discontinued treatment due to intolerable side effects and 5 patients (5%) did not achieve good compliance or were lost during follow up. However, 83 patients had successful eradication of H pylori with total eradication rates 83% (95 % CI 75.7-90.3%) and 88.30% (95 % CI 81.8-94.8%) according to an intention-to-treat and per-protocol analysis, respectively. Adverse events were reported in 21% of patients: abdominal pain (6%), nausea (9%) and constipation (12%), (2%) headache, and (1%) dizziness. A 2-week nitazoxanide-based regimen is an effective and safe rescue therapy in Egyptian patients whose previous standard triple therapy has failed.

Predictive value of serum insulin-like growth factor-1 in hepatocellular carcinoma.

BACKGROUND: Hepatocellular carcinoma (HCC) is the commonest primary malignant cancer of the liver in the world. Insulin-like growth factor-1 (IGF-1) levels reflect hepatic function and are inversely correlated with the severity of background chronic liver disease. OBJECTIVE: This study evaluated whether basal serum IGF-1 levels can predict prognosis of HCC patients according to different risks of disease progression. MATERIALS AND METHODS: A total of 89 patients with hepatocellular carcinoma (HCC) were recruited in 3 groups: Group I, 30 HCC patients receiving sorafinib; Group II, 30 HCC patients with best supportive care; and Group III include 29 patients undergoing transcatheter arterial chemoembolization (TACE). All patients were investigated for serum levels of AST, ALP, Bb, Cr, BUN, AFP and IGF-I. RESULTS: Patients with disease control had significantly higher baseline IGF-1 levels 210 (185-232.5) ng/mL (p value<0.01) than did patients without disease control. Low basal IGF-1 levels were associated with advanced HCC, such as multiple tumors and advanced stage, and low IGF-1 levels predicted shorter TTP and overall survival in patients treated with TACE. CONCLUSIONS: The levels of serum IGF-1, expressed as continuous values, may be helpful for accurately assessing hepatic function and the prognostic stratification of patients with HCC.
