Topical Cyclosporine-A for Management of Epiphora in Eyes with Acquired Punctal Stenosis

引用

Open Journal of Ophthalmology 2022年第3期12卷 209-217页

Background: Cyclosporine A (CsA) is an inhibitor of calcineurin that prevents T-cell production of inflammatory cytokines and disrupts the immune-mediated inflammatory response that plays a crucial mechanism in punctal stenosis. Purpose: To evaluate the clinical outcomes and tolerances of CsA in treating epiphora in eyes with punctal stenosis. Study Design: Prospective study. Methods: The study included patients who presented with symptomatic epiphora associated with lower punctal stenosis during the period between July 2019 and December 2020. Patients were treated with topical 0.05% CsA on twice daily dose with topical preservative-free artificial tears Q.I. D. Patients were followed up monthly for at least 3 months by Munk epiphora grading, Fluorescein dye disappearance test (FDT) and evaluation of the patient satisfaction. Results: A total of 26 patients with 47 eyes were included in the study with a mean age of 55.1 ± 10.24 years. All the eyes had grade 0 lower punctal stenosis with grade 4 on Munk grading and grade 3 in FDT. There was a statistically significant difference in the Munk grading and FDT along the follow-up period compared to the baseline values (p Conclusion: CsA can control the inflammation of the conjunctival sac and restore the integrity of the ocular surface with subsequent symptomatic relief of the epiphora in eyes with punctal stenosis.

World Journal of Gastroenterology 2006年第45期12卷 7337-7340页

AIM： To study the safety and efficacy of hepatitis A vaccine （HAV） in children with chronic liver disease of various etiologies. METHODS： Eleven children with chronic liver disease and thirteen age- and sex-matched controls negative for HAV antibodies were vaccinated against hepatitis A after they gave their informed consent. Children with uncontrolled coagulopathy or signs of hepatic decompensation were excluded. The vaccine （Havrix： 720 ELISA units in 0.5 mL, from GlaxoSmithKline Biologicals） was given intramuscularly in the deltoid in 2 doses 6 mo apart. Children were tested for HAV antibodies one and six months after the ist dose and one month after the 2^nd dose. Total serum bilirubin, alanine aminotransferase （ALT）, and aspartate aminotransferase （AST） were determined immediately before and after one month of the 1st dose of the vaccine. RESULTS： Only 7 out of the 11 patients were positive for HAV antibodies after the 1^st dose of the vaccine, as compared to 100% of the controls. One month after the 2nd dose, all patients tested were positive for HAV antibodies. No deterioration in liver functions of patients was noted after vaccination. No adverse events, immediate or late, were reported by the mothers after each dose of the vaccine. CONCLUSION： Hepatitis A vaccine is both safe and effective in this small studied group of children with chronic liver disease. Given the high seroconversion rate, post-vaccination testing for HAV antibodies is not needed.

AIM: To assess hepatic fibrosis and factors associated with its progression in children with HCV infection. METHODS: At the Hepatology Unit,Cairo University Children's Hospital,a single liver biopsy was performed to 43 children with HCV infection after an informed consent between 1998-2004. Their mean age at liver biopsy was 8.67 ± 4.3 years. RESULTS: Among the 43 patients' biopsies,12 (27.9%) were having no fibrosis,20 (46.5%) mild fibrosis and 11 (25.6%) moderate to severe fibrosis. The median time for development of fibrosis was estimated to be 5.5 years. Developing fibrosis was significantly associated with shorter duration from first detected ALT elevation to biopsy (12 mo vs 1.2 mo,P = 0.015) and having higher levels of direct serum bilirubin (0.3 mg/dL vs 0.5 mg/dL,P = 0.048). No association was found between fibrosis stage and the presence of co-morbid conditions (P = 0.33). CONCLUSION: Hepatic fibrosis was present in 72.1% of children with HCV infection. The development of fibrosis was associated with higher levels of direct serum bilirubin. There was no significant association between fibrosis and age,duration of infection,risk factors,co-morbid conditions and most biochemical parameters.

Prevalence of occult hepatitis C in egyptian patients with non alcoholic fatty liver disease

Open Journal of Internal Medicine 2011年第2期1卷 33-37页

This study aim is to assess the prevalence of occult HCV infection among Egyptian patients with non alcoholic fatty liver disease (NAFLD) with elevated AST and ALT, and to correlate presence of occult HCV with severity of liver disease. Patients and Methods: After informed consent 27 patients with elevateed liver enzymes diagnosed as NAFLD were examined for demographic, clinical, laboratory data and Ultrasonography. Liver biopsy was done and tested for HCV RNA in tissue. Genotyping using RFLP analysis of PCR products in the 5’NCR was done for positive cases. Results: HCV RNA in tissue was positive in 11/27 patients (40.7%);genotype was 4a in all positive cases. AST and ALT values showed significantly lower values in occult HCV than the non HCV NAFLD group. Liver biopsy of studied patients showed no significant difference as regard inflammation and fibrosis according to METAVIR score. Conclusions: Occult HCV is highly prevalent among Egyptian NAFLD patients. It seems to induce a mild liver disease. Patients with elevated ALT and negative HCV RNA in sera might be investigated for tissue HCV RNA. Follow up is recommended for the occult HCV patients to monitor progression to overt disease.
