The Update of Treatment for Primary Intestinal Lymphangiectasia

First case report of intestinal lymphangiectasia with refractory bleeding from the duodenum, successfully treated by intra-abdominal lymphaticovenous anastomosis with venous ligation

Intestinal lymphangiectasia (IL) is a protein-losing enteropathy (PLE) that occasionally leads to gastrointestinal bleeding (GIB). We encountered a 41-year-old female with a 9-year history of duodenal IL with PLE and GIB that progressively worsened. Despite a diet, supplemented with medium-chain triglycerides, antiplasmin therapy, oral corticosteroids, octreotides, sirolimus, and repeated endoscopic hemostasis, her symptoms remained uncontrolled, leading to blood transfusion dependence. Lymphangiography revealed significant leakage from abnormal abdominal lymph vessels into the duodenal lumen. The patient subsequently underwent an abdominal-level lymphaticovenous anastomosis combined with local venous ligation. This approach resulted in a dramatic improvement and sustained resolution of both the PLE and GIB. More than 6 months after surgery, the patient remained free of symptoms and blood transfusion dependence.

Gender differences in the association between dietary protein intake and constipation: findings from NHANES

Purpose

Dietary factors play a crucial role in the development and management of chronic constipation, yet the relationship between dietary protein intake and constipation remains underexplored. This study aims to investigate the association between dietary protein intake and the prevalence of constipation among American adults, with a focus on potential gender differences, using large-scale national data.

Materials and methods

Data from 14,048 participants aged 20 and above (7,072 men and 6,976 women) from the National Health and Nutrition Examination Survey (NHANES) 2005-2010 were analyzed. The Bristol Stool Form Scale's types 1 (separate hard lumps, resembling nuts) and 2 (sausage-shaped, but lumpy) were used to define constipation. A 24-h dietary recall technique was used to measure dietary protein intake. After controlling for covariates, the association between protein consumption and constipation risk was examined using multivariable logistic regression, smooth curve fitting, and testing for gender interaction effects. We then further determined the threshold effect between dietary protein intake and constipation risk.

Results

Constipation was present in 7.49% of people overall, with a higher proportion among women (10.19%) than among males (4.82%). In men, higher protein intake was significantly associated with a lower rate of constipation. However, in women, higher protein intake correlated with an increased risk of constipation, and the interaction between gender was significant (P for interaction = 0.0298). These results were corroborated by smooth curve fits, which also demonstrated a dose-response effect. Further threshold effect analysis showed that the turning points of dietary protein intake differed between male and female participants (119.42 gm/day for men; 40.79 gm/day for women).

Conclusion

The association between dietary protein intake and constipation was different in different genders with threshold effect. For men, moderately increasing protein intake could be beneficial, while for women, exceeding a certain level may increase the risk of constipation. These insights are crucial for guiding dietary protein recommendations for different genders and have significant clinical implications.

Other Causes of Chronic Diarrhea in Children

Chronic diarrhea is still an important cause of morbidity and mortality in children. There are several causes of chronic diarrhea which may be due to intestinal, extra-intestinal or underlying systemic diseases. The etiology varies depending on the age of onset and may include both common and uncommon disorders. In this article some of the uncommon disorders such as immune deficiencies, intestinal lymphangiectasias, drug induced diarrhea, eosinophilic gastrointestinal disorders, endocrinopathies, neuroendocrine secretory tumors, malignancy and factitious diarrhea have been included. Though these disorders are uncommon it is essential that they are considered in select situations as detailed below and evaluated so that definitive therapy may be offered.

Hypocalcaemic tetany linked to vitamin D deficiency and hypomagnesemia in primary intestinal lymphangiectasia: a literature review

Primary intestinal lymphangiectasia (PIL) is a rare disorder in children causing protein-losing enteropathy. Vitamin D deficiency and hypomagnesemia contributed to the tetany. The literature review reflects the importance of screening for these deficiencies and regular serum magnesium monitoring in PIL cases with neuromuscular or ionic abnormalities.

Solitary Intestinal Lymphangiectasia Causing Transient Intussusception

Lymphangiectasia is the benign malformation of lymphatic channels associated with either focal or diffuse dilation of vessels and impaired lymph drainage. This malformation has the potential to create a cystic mass due to the accumulation of lymphatic fluid. While rare in adults, intussusception, the telescoping of the proximal bowel into the distal bowel, can be caused by a mass within the bowel. In this case, a near-obstructing cystic colon mass developed in a 74-year-old man; this was later found to be a large lymphangiectasia. In addition, this near-obstructing colonic lymphangiectasia served as the lead point in a colo-colonic intussusception. Due to this complication, the mass was immediately removed by a laparoscopic oncologic right-extended hemicolectomy which proved to be both diagnostic and therapeutic.

Adult-Onset Primary Intestinal Lymphangiectasia With Liver Enzymes Elevation

Primary intestinal lymphangiectasia is a rare disorder that may result in protein-losing enteropathy. We report a 21-year-old man with malabsorption syndrome, an unintentional weight loss of 30 kg over 10 months, lymphocytopenia, and hepatic aminotransferase elevation. His diagnosis was established by a combination of enteroscopy, histopathology, and secondary etiology exclusion. Institution of parenteral nutrition, followed by a low-fat diet, medium-chain triglycerides, and octreotide, resulted in the resolution of his symptoms and laboratory abnormalities and led to weight gain. Aminotransferase abnormalities are an atypical finding in primary intestinal lymphangiectasia and were most likely due to nonalcohol steatohepatitis after rapid weight loss. Primary intestinal lymphangiectasia should be considered in patients with protein-losing enteropathy and lymphocytopenia.

Embolization in Pediatric Patients: A Comprehensive Review of Indications, Procedures, and Clinical Outcomes

Embolization in pediatric patients encompasses a large spectrum of indications, ranging from the elective treatment of congenital diseases of the cardiovascular system to the urgent management of acute hemorrhagic conditions. In particular, the endovascular treatment of central and peripheral vascular malformations and hypervascular tumors represents a wide chapter for both congenital and acquired situations. Thanks to the progressive availability of low-profile endovascular devices and new embolic materials, the mini-invasive approach has gradually overtaken surgery. In this review, the main embolization procedures will be illustrated and discussed, with a focus on clinical indications and expected outcomes. The most recent mini-invasive techniques will be described, with hints on the cutting-edge devices and embolic materials.

Pathophysiology, Diagnosis, and Management of Canine Intestinal Lymphangiectasia: A Comparative Review

Intestinal lymphangiectasia was first described in the dog over 50 years ago. Despite this, canine IL remains poorly understood and challenging to manage. Intestinal lymphangiectasia is characterized by variable intestinal lymphatic dilation, lymphatic obstruction, and/or lymphangitis, and is a common cause of protein-losing enteropathy in the dog. Breed predispositions are suggestive of a genetic cause, but IL can also occur as a secondary process. Similarly, both primary and secondary IL have been described in humans. Intestinal lymphangiectasia is definitively diagnosed via intestinal histopathology, but other diagnostic results can be suggestive of IL. Advanced imaging techniques are frequently utilized to aid in the diagnosis of IL in humans but have not been thoroughly investigated in the dog. Management strategies differ between humans and dogs. Dietary modification is the mainstay of therapy in humans with additional pharmacological therapies occasionally employed, and immunosuppressives are rarely used due to the lack of a recognized immune pathogenesis. In contrast, corticosteroid and immunosuppressive therapies are more commonly utilized in canine IL. This review aims toward a better understanding of canine IL with an emphasis on recent discoveries, comparative aspects, and necessary future investigations.
