Clinical and Biochemical Predictors of Nonalcoholic Fatty Liver Disease among Type 2 Diabetes Mellitus Patients at Primary Health Care Level in South Western Saudi Arabia.

OBJECTIVES: To predict the role of different clinical and biochemical parameters in identifying nonalcoholic fatty liver disease (NAFLD) among patients with type 2 diabetes mellitus (T2DM) in Abha city, southwestern Saudi Arabia. METHODS: A stratified random sample was selected. A detailed clinical and biochemical examinations were performed. Using portable abdominal ultrasound examination, NAFLD was identified. The study used receiver operating characteristic (ROC) analysis. RESULTS: The study covered 237 T2DM patients. NAFLD was detected among 174 patients. Area under the curve (AUC) calculations showed that the ability of age, duration of DM in years, and body mass index to predict NAFLD was poor (AUC < 0.6). Similarly, biochemical factors like HbA1c%, AST, cholesterol, triglycerides, HDL, LDL, and VLDL were poor in discriminating between those with and without NAFLD among T2DM. On the other hand, the ability of ALT to predict NAFLD among T2DM was good (AUC = 0.701, 95% CI: 0.637-0.761). The analysis identified the optimal cutoff point of ALT to be ≤22.1 nmol/L. The corresponding sensitivity was 60.7% (95% CI: 53.0-68.0) and specificity was 62.5% (95% CI: 49.5-74.3). CONCLUSIONS: Early identification of NAFLD among T2DM is important. A threshold cutoff value of 22.1 nmol/L of ALT has been identified to predict NAFLD. They should be referred for ultrasound examination for NAFLD.

Non-Alcoholic Fatty Liver Disease among Type-2 Diabetes Mellitus Patients in Abha City, South Western Saudi Arabia.

The objective of this study was to determine the prevalence and the factors associated with non-alcoholic fatty liver disease (NAFLD) among type-2 diabetes mellitus (T2DM) patients in Abha City, Southwestern Saudi Arabia. Using a cross-sectional study design, a representative sample of 245 T2DM patients were recruited from all primary healthcare centers in Abha city. A detailed medical history as well as laboratory investigations were done. NAFLD was diagnosed using abdominal ultrasound examination. The overall prevalence of NAFLD was 72.8% (95% CI: 66.6%⁻78.1%). In a multivariable regression analysis, the risk of NAFLD was significantly higher among overweight T2DM patients (aOR = 6.112, 95% CI: 1.529⁻4.432), Obese (aOR = 10.455, 95% CI: 2.645⁻41.326), with high ALT of more than 12 IU/L (aOR = 2.335, 95% CI: 1.096⁻5.062), moderate diet-compliant patients (aOR = 2.413, 95% CI: 1.003⁻5.805) and poor diet-compliant patients (aOR = 6.562, 95% CI: 2.056⁻20.967). On the other hand, high HDL (high density cholesterol) (in mg/dL) was a protective factor for NAFLD (aOR = 0.044, 95% CI: 0.005⁻0.365). It was concluded that NAFLD is a common association of T2DM. Increasing BMI (Body mass index), lower HDL level, and poor dietary control are significant factors associated with NAFLD among T2DM patients. Health education to improve dietary control and avoid excessive weight gain, testing for NAFLD among diabetic patients, especially those with abnormal BMI and HDL, are recommended for early detection and to ensure optimal levels of HDL.

Hepatitis C Virus Infection at Primary Healthcare Level in Abha City, Southwestern Saudi Arabia: Is Type 2 Diabetes Mellitus an Associated Factor?

BACKGROUND: There is an increasing concern about the relation between hepatitis C virus infection (HCV) and type 2 diabetes mellitus (T2DM). The present study aims to determine the prevalence of HCV infection among T2DM patients and non-diabetic patients attending primary healthcare centers (PHCCs) in Abha city, southwestern Saudi Arabia, and to explore the possible association between T2DM and HCV infection. METHODS: A cross-sectional study targeting a random sample of T2DM and non-diabetic patients attending PHCCs in Abha City was conducted. Patients were interviewed using a structured questionnaire and screened for HCV infection using fourth-generation ELISA kits. All positive cases were confirmed by qualitative RT-PCR immune assay. RESULTS: The study revealed an overall seroprevalence of HCV infection of 5% (95% CI: 2.9⁻7.9%). Among T2DM and non-diabetics, a seroprevalence of 8.0% and 2.0% was found, respectively. Using multivariable regression analysis, the only significant associated factor for HCV infection was T2DM (aOR = 4.185, 95% CI: 1.074⁻16.305). CONCLUSIONS: There is strong positive association between T2DM and HCV infection. Yet, the direction of relationship is difficult to establish. Patients with T2DM have higher prevalence of HCV infection than non-diabetic group. It is highly recommended for primary health care providers to screen for HCV infection among T2DM patients and to increase the level of HCV awareness among them.

Feasibility of cord blood bank in high altitude Abha: preclinical impacts.

We explored the possibility of the cryo-storage of cord blood hematopoietic stem cells (CBHPSC) with respect to the quantity, quality and biologic efficacy of high altitude (HA) region Abha against sea level (SL) region. The results of the post-processed total nucleated cell count was 8.03 ± 0.31 × 107 and 8.44 ± 0.23 × 107 cells in the HA and SL regions respectively. The mean post processing viability of the nucleated cells was about 87.03 ± 1.39 (HA) and 88.33 ± 1.55% (SL) while post thaw cells were 85.61 ± 1.44 (HA) and 86.58 ± 1.61% (SL) after transient cryo-storage. The proliferation of CBHSCs after thawing were comparable between the HA and SL regions. The results of the colony forming unit (CFU) assays of CFU-E, CFU-GEMM, CFU-GM and BFU-E were comparable between HA and SL in both fresh and post thaw, while a declining trend with viability was significant. The differentiation capability of post thaw samples into adipocytes and osteocytes were comparable between HA and SL regions. Overall from the results, it can be evidenced that HA cord blood collection, processing or storage does not hinder the quality or biological efficacy of the CBHPSC.

Endoscopic Treatment of Biliary Leak Following Gunshot Injury: A Case Report.

This report describes the endoscopic treatment of a biliary leak following a gunshot injury in a young Saudi female. She was admitted to the emergency unit having sustained an accidental gunshot on the upper part of her right shoulder when her spouse was maintaining his gun sitting on a higher level chair. She was intubated and immediately taken for exploratory laparotomy, which revealed right liver lobe laceration and significant hemoperitoneum. Bleeding was controlled surgically, and two peritoneal lavage catheters were inserted for drainage. However, about 300-400 ml of bile drainage was observed daily. Accordingly, endoscopic retrograde cholangiopancreatography (ERCP) was performed, which demonstrated a biliary leak. Sphincterotomy was performed and a stent was inserted, following which bile drainage gradually reduced, and stopped after 5 days. A follow-up ERCP was performed 10 weeks later, and no further leak was observed. This is the first case report of a successful endoscopic treatment of traumatic biliary injuries due to a gunshot in Saudi Arabia. ERCP is a valuable method in the treatment of a traumatic bile leak.

Hepatitis B and C Viral Infections in Tihamet Aseer, South-Western Saudi Arabia: Are There Gender Differences?

BACKGROUND: Hepatitis B virus (HBV) infection is endemic in Saudi Arabia. Many studies have shown varying results in gender differences in HBV and hepatitis C virus (HCV) infection. The objective of this study was to determine if gender differences exist in HBV and HCV infection and to elucidate any related risk factors in Tihamet Aseer, south-western Saudi Arabia. MATERIALS AND METHODS: The study was a cross-sectional study of a representative sample of males and females in Tihamet Aseer, south-western Saudi Arabia. A comprehensive questionnaire was completed by all participants. Blood samples were taken and sera were tested for hepatitis B surface antigen and HCV antibodies by fourth-generation enzyme immunoassays. RESULTS: The study included 1532 participants from the Tihamet Aseer area. An overall seroprevalence of 7.9% and 1.7% was found for HBV and HCV infections, respectively. In logistic regression analysis, no gender differences were found for HBV seroprevalence. Identified risk factors for HBV infection included a history of blood transfusion and lack of hepatitis B vaccination. On the other hand, females were more prone to become seropositive for HCV (adjusted odds ratio = 5.034, 95% confidence interval: 1.042-9.321). Other identified risk factors for HCV infection were illiteracy and a history of blood transfusion. CONCLUSION: The prevalence and HBV and HCV infection is high compared to the national figures. Gender differences were only observed in HCV infection. It is recommended to have an active educational and media campaign. A "catch-up" vaccination program against HBV should be introduced for adults as a strategy to achieve the herd immunity effect in the affected area.

Hepatitis C virus infection in southwestern Saudi Arabia: Are we still in the plateau phase?

The aim was to study the seroprevalence of Hepatitis C virus (HCV) infection and related risk factors in Aseer region in southwestern Saudi Arabia, the region known to be of the highest endemicity of viral hepatitis. In a cross-sectional study, all participants were interviewed using structured questionnaire. HCV infection was diagnosed using fourth-generation ELISA. All positive and equivocal HCV serology results were further confirmed by using a qualitative confirmatory RT-PCR. The study enrolled 10,234 participants. A seroprevalence of 2.2% (95%CI: 1.9-2.5%) was found. In multivariate logistic regression analysis, the study showed that males had significantly more risk to become seropositive for HCV (aOR = 1.437, 95%CI: 1.071-1.927) compared to females. Similarly, participants having history of blood transfusion had more than two times the risk of becoming seropositive for HCV (aOR = 2.079, 95%CI: 1.037-4.149). HCV infection in the study area is still high in the plateau phase. It is recommended to have an active educational and media campaign about the risks of HCV infections. Workshops and training of qualified laboratory staff related to blood banking seem mandatory. J. Med. Virol. 89:867-871, 2017. © 2016 Wiley Periodicals, Inc.

Choledochocele: the disputed origin.

Choledochocele is classified as a type III choledochal cyst according to Alonso-Lej classification. Although it is anatomically related to the common bile duct, it does not share the strong premalignant potential of the more common types of choledochal cysts. In addition, duodenal mucosa has been found lining many of these cysts. These findings pose certain disputes about their possible origin, necessitating revision of the current inclusion of choledochocele with choledochal cysts.
