A Case of Mediastinal Lymphangioma Successfully Treated with Kampo Medicine

Effect of Japanese Kampo medicine, eppikajutsuto, in patients with lymphatic malformation: A retrospective observational study

Lymphatic malformations (LMs) are congenital malformations of the lymphatic system that cause considerable cosmetic and functional complications. In this study, we present 8 children with LM who were treated with the Kampo medicine eppikajutsuto (EKJT).Between 2001 and 2020, 8 children (male: 4, female: 4) with LMs who underwent magnetic resonance imaging (MRI) evaluation both before and after treatment or observation were selected for investigating the effect of EKJT. Two patients were observed without any treatment for 24 and 60 months. EKJT was evaluated based on percentage reduction, defined as the percentage of total lesions that decreased in size, confirmed by radiological examination after initiating treatment with EKJT or determined by observation alone. Volumetric analysis of LMs on MRI was performed using the Digital Imaging and Communications in Medicine viewer.Six patients were treated with EKJT. The mean observational period was 13.2 months (range: 6-24 months). The mean reduction in LM volume on MRI was 73.0% in treated patients and -66.3% in observed patients. Two of the 6 lesions exhibited complete reduction, 2 exhibited marked (>90%) reduction, 1 exhibited moderate reduction, and 1 exhibited a small response. The treatment was well-tolerated, with no severe adverse events.This preliminary study demonstrated the beneficial effects of EKJT. Prospective evaluations of this promising therapeutic modality are warranted based on the results of this study.

Acquired cryptorchidism: an unexpected consequence of inguinoscrotal lymphatic malformation treated with Eppikajutsuto

Lymphatic malformation (LM) that causes inguinoscrotal swelling is extremely rare. Surgery, sclerotherapy and pharmacotherapy have been reported as possible treatment options for LM. Recently, Eppikajutsuto (TJ-28), a traditional Japanese herbal medicine has emerged as therapeutic option for LM. We report the case of a 2-year-old boy who presented with a left inguinoscrotal swelling, which was diagnosed as retroperitoneal LM extending into the left scrotum. The surgical approach was less favourable, given the risk of damaging the testicular vasculature or the spermatic cord. Therefore, the patient received medical treatment with TJ-28. As a result, a volume reduction of 83% was obtained, as well as the unexpected consequence of the left testicle retracting into the inguinal area. Laparoscopic exploration was performed and a small bulge on the internal inguinal ring was detected. The patient's acquired cryptorchidism was subsequently treated by orchidopexy.

Histopathological evaluation of the effectiveness of oral Eppikajutsuto treatment for lymphatic malformation

BACKGROUND

Lymphatic malformation (LM) is a congenital disease caused by lymphatic vessel malformation. Although standard therapies for LMs are sclerotherapy and/or surgical excision, a new therapy using Japanese herbal medicine Eppikajutsuto (TJ-28) has been recently reported as clinically effective. We aimed to experimentally confirm the therapeutic effectiveness of TJ-28 for LMs.

METHODS

LM lesions were generated in the mesentery and peritoneum of mice by intraperitoneal injection of Freund's incomplete adjuvant. Mice with LMs were treated by gavage or dietary administration of TJ-28 for 2 months. Formalin-fixed paraffin-embedded tissue sections of mesentery and peritoneum tissues were histologically and immunohistochemically examined by focusing on lymph nodes and perinodal lymph vessels.

RESULTS

Multiple Freund's incomplete adjuvant-associated foreign-body granulomas were formed in the mesentery and peritoneum, resulting in congestion of lymph fluid and dilatation of lymph vessels. The numbers and sizes of lymph nodes were not significantly different between TJ-28-treated and control groups. However, the luminal areas of lymphatic vessels were reduced significantly in the TJ-28 treatment group by both gavage and dietary administrations.

CONCLUSION

TJ-28 conspicuously reduced congestion of lymph fluid. This is the first histopathological evaluation of LM model mice to study the effectiveness of oral TJ-28 treatment.

Japanese clinical practice guidelines for vascular anomalies 2017

The objective was to prepare guidelines to perform the current optimum treatment by organizing effective and efficient treatments of hemangiomas and vascular malformations, confirming the safety, and systematizing treatment, employing evidence-based medicine (EBM) techniques and aimed at improvement of the outcomes. Clinical questions (CQs) were decided based on the important clinical issues. For document retrieval, key words for literature searches were set for each CQ and literature published from 1980 to the end of September 2014 was searched in Pubmed, Cochrane Library, and Japana Centra Revuo Medicina (JCRM). The strengths of evidence and recommendations acquired by systematic reviews were determined following the Medical Information Network Distribution System (MINDS) technique. A total of 33 CQs were used to compile recommendations and the subjects included efficacy of resection, sclerotherapy/embolization, drug therapy, laser therapy, radiotherapy, and other conservative treatment, differences in appropriate treatment due to the location of lesions and among symptoms, appropriate timing of treatment and tests, and pathological diagnosis deciding the diagnosis. Thus, the Japanese Clinical Practice Guidelines for Vascular Anomalies 2017 have been prepared as the evidence-based guidelines for the management of vascular anomalies.

A single institution experience of Eppikajutsuto for the treatment of lymphatic malformations in children

BACKGROUND

Eppikajutsuto (TJ-28) is an herbal medicine recently reported to be effective in treating lymphatic malformations (LMs). We report our experience concerning the clinical efficacy of TJ-28 for LMs.

METHODS

Medical records of 10 LM cases treated with TJ-28 between 2016 and 2018 were reviewed. TJ-28 was given at 0.3 g/kg/day and then increased to 0.5 if no improvement was noted after the first three months of treatment. Their clinical data were collected, and LM volume indices (depth×width×height) were measured with the first (LMVI-F) and latest (LMVI-L) imaging studies. The response rates were calculated as 1-LMVI-L / LMVI-F (%).

RESULTS

The median age at the diagnosis and treatment period was 1.5 years and 17.5 months, respectively. LMs were located in the neck (six), mesenterium or retroperitoneum (three), and inguinal region (one). The median response rate was 83%, including 100% in three cases and the apparent improvement of obstructive airway symptoms in one case. One case underwent surgery for insufficient improvement, and another that showed no effect is being considered for surgery. Most of the satisfactory outcomes were demonstrated in the first six months of treatment.

CONCLUSION

TJ-28 seems to be effective in treating LMs in children, especially early in treatment.

A Case of Suspected Adverse Reactions to Sirolimus in the Treatment of Generalized Lymphatic Anomaly

Generalized lymphatic anomaly (GLA) is characterized by diffuse or multicentric proliferation of dilated lymphatic vessels resembling common lymphatic malformation, and thoracic lesions can be related to a poor prognosis. Sirolimus, an inhibitor of the mammalian target of rapamycin, is effective against vascular anomalies with few severe adverse drug reactions. Here, we report the case of a patient with intractable hemothorax pleural effusion due to GLA who was treated with sirolimus and experienced disseminated intravascular coagulation. Although a standard treatment for GLA has not been established, pleural fluid might be reduced using the Kampo medicine Eppikajyutsuto.

Prenatally diagnosed large mediastinal lymphangioma: A case report

Thoroughly planned labor with immediate postnatal resuscitation and percutaneous decompression is mandatory for a large mediastinal lymphangioma that compromises the cardiopulmonary function, and close observation with the administration of Eppikajutsuto (TJ-28), a Japanese herbal medicine, may be a reasonable treatment, especially when resection of the lesion seems technically challenging.

A large retroperitoneal lymphatic malformation successfully treated with traditional Japanese Kampo medicine in combination with surgery

BACKGROUND

Current treatment options for lymphatic malformations (LMs) are multimodal. Recently, the effectiveness of treating LMs with Eppikajyutsuto (TJ-28) has been reported. TJ-28 is a kind of oral herbal medicine classified as the traditional Japanese Kampo medicine.

CASE PRESENTATION

A 12-year-old girl was admitted to our hospital for intermittent upper abdominal pain. Radiological examinations revealed a large (9.5 × 5.8 × 10.0 cm) retroperitoneal LM, which was suspected to adhering and stretching both pancreas head and duodenum. The large retroperitoneal tumor resection might induce involving complications because of the size and the location. Therefore, we used TJ-28 in order to diminish the tumor size before surgery. The patient received oral doses of 7.5 g/day (2.5 g × 3 times/day) of TJ-28. Six months after the medication, the tumor decreased markedly to 3.5 × 1.5 × 1.2 cm in size. Thereafter, the mass was sub-totally resected (95%) via a 3 cm trans-umbilical incision without any surgical complications.

CONCLUSIONS

We reported a case of successfully treated retroperitoneal LM with the combination treatment of TJ-28 and surgery. Based on our experience, this TJ-28 treatment option may be very useful in treating cases of LMs having surgical difficulties because of size and/or location.

Clinical Efficacy of Herbal Medicine for Pediatric Lymphatic Malformations: A Pilot Study

BACKGROUND

Lymphatic malformations (LMs) are congenital malformations of the lymphatic system that commonly affect the head and neck region and cause marked cosmetic and functional complications. In this pilot study, we present eight children with LMs treated using an herbal medicine for this indication.

METHODS

Between January 2009 and May 2014, eight children (four boys, four girls) with LMs were treated using oral administration of an herbal medicine, Eppikajyutsuto (TJ-28; Tsumura, Tokyo, Japan), as monotherapy.

RESULTS

Four of the cases were macrocystic and four were mixed micro- and macrocystic. The mean treatment duration was 7.2 ± 2.9 months (range 5-12 mos). The mean LM volume shrinkage on magnetic resonance imaging was 54.5 ± 38.3% (macrocystic 73.6 ± 27.0%; mixed micro- and macrocystic 35.4 ± 41.5%). One of four macrocystic lesions had a marked reduction, two had a moderate reduction, and one had no response. A marked reduction was observed in three of the four mixed micro- and macrocystic cases; the other mixed cystic case had no response. The treatment was well tolerated, without severe adverse events.

CONCLUSIONS

This preliminary study demonstrates the beneficial effects of TJ-28. Further evaluations of this therapeutic modality are warranted.
