Ethanolamine oleate versus botulinum toxin in the treatment of idiopathic achalasia.

Ann Gastroenterol 2015 Apr-Jun;28(2):229-235

Department of Gastroenterology, Digestive Disease Research Institute, Shariati Hospital, Tehran University of Medical Sciences (Javad Mikaeli, Arash Kazemi Veisari, Narges Fazlollahi, Narges Mehrabi, Hossein Asl Soleimani, Reza Malekzadeh), Tehran, Iran.

Background: Botulinum toxin (BT) injection reduces lower esophageal sphincter pressure and alleviates symptoms in idiopathic achalasia (IA). Ethanolamine oleate (EO) has also been introduced for the treatment of IA. We compared the long-term efficacy of BT and EO injections in the treatment of IA.

Methods: A total of 189 IA patients were evaluated prospectively, of whom 21 were unwilling to undergo or were poor candidates for pneumatic balloon dilation and Heller myotomy and were enrolled in the study. Eleven patients were treated by BT, and 10 by EO injections. Patients were followed up by achalasia symptom score (ASS), timed barium esophagogram (TBE), and high-resolution manometry at baseline and post-treatment. A good initial response was defined as a decrease in ASS to 4 or less, and a reduction in barium column height and volume in TBE by >50%.

Results: All 10 EO group patients and 10 of 11 BT group patients showed a good initial response. Four EO group relapsers and 6 BT group relapsers were managed effectively by re-injections. Mean duration of follow up was 27.38 months. On completion of the study, a sustained good response was seen in 9 and 6 patients in EO and BT groups, respectively (P=0.149).

Conclusion: This study revealed that BT and EO have comparable efficacy in the treatment of IA. However, the cost of EO is about 2 times lower than BT.

Ethanolamine oleate in resistant idiopathic achalasia: a novel therapy.

Eur J Gastroenterol Hepatol 2011 Nov;23(12):1111-5

Digestive Disease Research Center, Faculty of Pharmacy, Shiraz University of Medical Sciences, Shiraz, Iran.

Objectives: Idiopathic achalasia (IA) is a chronic disease without definite therapy. Ethanolamine oleate (EO) has multiple biological effects, including inflammatory activities. We investigated the efficacy of EO injection in selected patients with IA.

Methods: One hundred and thirty-six patients with IA were evaluated prospectively. We evaluated the efficacy of EO injection in 13 patients with IA that are resistant to or a poor candidate of pneumatic balloon dilation and/or cardiomyotomy at the Digestive Disease Research Center, Shariati Hospital, Tehran, as the major referral center for achalasia in Iran in an interventional study. Diluted EO was injected in a divided dose into each of four quadrants of lower esophageal sphincter, using a standard sclerotherapy needle. Injection was repeated at 2 and 4 weeks after first injection. The patients were evaluated with achalasia symptom score (ASS) and timed barium esophagogram (TBE) before and after injections. Good response was defined as a decrease in ASS of at least 50% of baseline and decrease in height and volume of barium of at least 50% of baseline in TBE, at 1.5 months after the last injection. Side-effects were recorded.

Results: All patients (13 cases) had good ASS (decreased, ≥ 50%) and good TBE (decreased in height and volume of barium, ≥ 50%) response rate. The mean ASS decreased from 11.38 (± 1.5) to 3.23 (± 1.96) at 1.5 months after the last injection (P=0.001). The mean volume of barium in TBE decreased from 81.38 ml (± 51.11) to 40.69 ml (± 61.22) at 1.5 months after the last injection (P=0.016). The mean duration of follow-up was 17.83 (± 1.12) months. Symptoms of six patients relapsed; all of them were treated effectively with reinjection.

Conclusion: This study indicates that EO is well tolerated and potentially effective in patients with IA that might be explained by the local inflammatory properties of EO. As presented data are too preliminary to support the routine use of EO in the treatment of all patients with IA; its use in selected cases can be considered.

Hepatitis B Virus Infection during Pregnancy: Transmission and Prevention.

Middle East J Dig Dis 2011 Sep;3(2):92-102

Digestive Disease Research Center, Shariati Hospital, Tehran University of Medical Sciences, Tehran, Iran.

Hepatitis B virus (HBV) infection is a global public health problem. In endemic areas, HBV infection occurs mainly during infancy and early childhood, with mother to child transmission (MTCT) accounting for approximately half of the transmission routes of chronic HBV infections. Prevention of MTCT is an essential step in reducing the global burden of chronic HBV. Natal transmission accounts for most of MTCT, and providing immunoprophylaxis to newborns is an excellent way to block natal transmission. Prenatal transmission is responsible for the minority of MTCT not preventable by immunoprophylaxis. Because of the correlation between prenatal transmission and the level of maternal viremia, some authors find it sound to offer lamivudine in women who have a high viral load (more than 8 to 9 log 10 copies/mL). In addition to considerations regarding the transmission of HBV to the child, the combination of HBV infection and pregnancy raises several unique management issues. Chronic HBV infection during pregnancy is usually mild but may flare after delivery or with discontinuing therapy. Management of chronic HBV infection in pregnancy is mostly supportive with antiviral medications indicated in a small subset of HBV infected women with rapidly progressive chronic liver disease.
