RESUMO

BACKGROUND: Pakistan has one of the highest burdens of Hepatitis C virus (HCV) infection globally. To achieve the World Health Organization's goals for HCV elimination, there is a need for substantial scale-up in testing, treatment, and a reduction in new infections. Data on the population impact of scaling up treatment is not available in Pakistan, nor is there reliable data on the incidence of infection/reinfection. This project will fill this gap by providing important empirical data on the incidence of infection (primary and reinfection) in Pakistan. Then, by using this data in epidemic models, the study will determine whether response rates achieved with affordable therapies (sofosbuvir plus daclatasvir) will be sufficient to eliminate HCV in Pakistan. METHODS: This prospective multi-centre cohort study will screen 25,000 individuals for HCV antibody (Ab) and RNA (if Ab-positive) at various centers in Pakistan- Karachi (Sindh) and Punjab, providing estimates of the disease prevalence. HCV positive patients will be treated with sofosbuvir and daclatasvir for 12-weeks, (extended to 24-weeks in those with cirrhosis) and the proportion responding to this first-line treatment estimated. Patients who test HCV Ab negative will be recalled 12 months later to test for new HCV infections, providing estimates of the incidence rate. Patients diagnosed with HCV (~ 4,000) will be treated and tested for Sustained Virological Response (SVR). Questionnaires to assess risk factors, productivity, health care usage and quality of life will be completed at both the initial screening and at 12-month follow-up, allowing mathematical modelling and economic analysis to assess the current treatment strategies. Viral resistance will be analysed and patients who have successfully completed treatment will be retested 12 months later to estimate the rate of re-infection. CONCLUSION: The HepFREEPak study will provide evidence on the efficacy of available and widely used treatment options in Pakistan. It will also provide data on the incidence rate of primary infections and re-infections. Data on incidence risk factors will allow us to model and incorporate heterogeneity of risk and how that affects screening and treatment strategies. These data will identify any gaps in current test-and-treat programs to achieve HCV elimination in Pakistan. STUDY REGISTRATION: This study was registered on clinicaltrials.gov (NCT04943588) on June 29, 2021.

RESUMO

Synonymous with congenital non-obstructive saccular or fusiform intra-hepatic duct dilatation and congenital communicating cavernous ectasia of the intra-hepatic biliary tract, Caroli's syndrome (CS) is an extremely rare fibro-polycystic liver disorder characterized by ductal plate malformation and consequent peri-portal fibrosis due to segmental intra-hepatic duct dilatation. No more than 200 cases of the syndrome have been reported since 1958. CS may affect one or both lobes of the liver, but more commonly it affects the left hepatic lobe. We describe a rare case of CS localized to the right hepatic lobe in a 21-year-old male, who presented with complaints of upper gastrointestinal (GI) bleeding without any signs or stigmata of chronic liver disease. Personal as well as family history was non-significant except positive for consanguineous parental marriage. General physical examination was unremarkable except for pallor, and upper GI endoscopy revealed columns of bandable esophageal varices which led us to a line of investigations to identify the cause of portal hypertension. Blood tests were non-specific, though imaging studies chiefly abdominal ultrasound, CT abdomen and pelvis with contrast, and magnetic resonance cholangiopancreatography (MRCP) led us to confirmation of the diagnosis of CS in the right hepatic lobe with manifestations of portal hypertension as the predominant feature. Diagnosis was confirmed on liver biopsy which showed right-sided cystic dilations with congenital hepatic fibrosis.

RESUMO

Background Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by high blood sugar levels, insulin resistance, and relative insulin deficiency. Metabolic dysfunction-associated steatotic liver disease (MASLD) is the term used to describe fatty liver (steatosis) in individuals without a history of significant alcohol intake. MASLD is progressively known as the leading cause of chronic liver disease. Dietary factors, a significant risk factor for developing T2DM and cardiovascular disease, also contribute to MASLD development. The risk of developing MASLD increases with age, particularly in patients with diabetes mellitus. This risk is notably elevated among South Asians due to their higher incidence of insulin resistance and metabolic syndrome. Importantly, MASLD is acknowledged as a component of the metabolic syndrome, with insulin resistance playing a central role in its development. Objective To determine the association between MASLD and T2DM in patients presenting at a tertiary care hospital in Pakistan. Methodology This case-control study was conducted for one year in a tertiary care hospital in Gujranwala, Pakistan. A total of 380 patients were enrolled through convenient sampling and were analyzed according to two groups: those with diabetes (case) and those without diabetes (control). All participants were assessed for serum aspartate transaminase (AST) and alanine transaminase (ALT) levels and underwent abdominal ultrasound to determine hepatic fibrosis. A diagnosis of MASLD was made only in the presence of hepatic steatosis with AST and ALT values of more than 40 IU. The odds ratio (OR) was calculated, and stratified analysis was conducted according to gender, age, and BMI. A p-value of ≤0.05 was considered statistically significant. Results In our study, 55.53% of patients were male, while 44.47% were female. The average BMI (±SD) of the patients was 23.66±3.08 kg/m2. Among the cases group, the MASLD was noted in 91 (47.9%) patients, while among the controls group, the MASLD was noted in 64 (33.7%) patients with a statistically significant OR of 1.810 (1.19-2.74). Conclusion In conclusion, MASLD is significantly associated with T2DM, regardless of gender and BMI of patients. We recommend screening T2DM patients for the presence of MASLD at regular intervals to prevent hazardous consequences of MASLD in adult populations, particularly those with features of metabolic syndrome. Further larger-scale studies investigating the impact of T2DM on MASLD are required to reduce morbidity and decrease disease burden, especially in prevalent areas.

RESUMO

Background Upper gastrointestinal bleeding (UGIB) is a common medical emergency that results in significant morbidity, mortality, and socioeconomic burden. Both types of cardio-fundal varices, gastro-esophageal varix 2 (GOV2) and isolated gastric varices type 1 (IGV1), can cause massive bleeding and often are difficult to treat compared to the other types of gastric varices. Endoscopic variceal band ligation (EVBL) is a less effective treatment modality for gastric varices than esophageal varices and is associated with high re-bleeding rates. N-butyl-2-cyanoacrylate (Histoacryl) injection is an effective and potential treatment option for fundal varices. This study aims to evaluate the safety and efficacy of n-butyl-2-cyanoacrylate injection therapy in cardio-fundal varices. Objective To assess the efficacy and safety of n-butyl-2-cyanoacrylate injection therapy for fundal varices. Methods This retrospective observational cohort study was conducted at the Department of Gastroenterology, Allied Teaching Hospital, Gujranwala, over one year. All patients, irrespective of age and gender, presenting with UGIB and in whom fundal varices were diagnosed on gastroscopy followed by n-butyl 2-cyanoacrylate injection therapy were included in this study. The efficacy and safety of Histoacryl therapy were assessed by analyzing successful hemostasis, frequency of re-bleeding, obliteration, and regression of fundal varices on repeat endoscopy. Adverse events such as re-bleeding and mortality related to fundal variceal treatment were documented. Results A total of 60 patients were included in the study. Of these, 70% had IGV1, while the remaining 30% had GOV2. Hemostasis was achieved in 100% of patients following n-butyl-2-cyanoacrylate injection. Successful obliteration with regression of varices was observed in 91.3% of patients. Various adverse events were observed, with abdominal pain being the most common observed complication in 18.3% of participants. However, only 8.3% of participants developed re-bleeding due to ulcer formation at the injection site, and no death occurred directly due to fundal variceal treatment. Conclusion N-butyl-2-cyanoacrylate injection therapy is a lifesaving, effective, and safe intervention for controlling bleeding from cardio-fundal varices, leading to improved health status and a consequent decrease in episodes of recurrent bleeding. Its side effects are few and infrequent. However, larger-scale studies are needed to further evaluate the safety and effectiveness of n-butyl-2-cyanoacrylate injection therapy. These studies will be crucial in establishing comprehensive guidelines for the management of fundal varices.

RESUMO

The incidence of dengue has been on the upsurge in the last decade. It has affected around one-third of the world's population living in endemic areas. It can be asymptomatic or may present with some specific symptoms. No control measures have proven beneficial to decrease the prevalence of this disease. The emergence of dengue vaccine has been a revolutionary hope in the future of patients affected with this disease. No doubt, this vaccine has its limitations and may do more harm than good, but with correct use, it can prove to be the most beneficial step taken in managing dengue so far.
