On account of presentation and results of investigations the case was diagnosed as being a case of:
Nephrotic syndrome in relapse, complicated with spontaneous bacterial peritonitis.
The patient was given treatment in the form of I.V antibiotics, I.V fluids and stress dose coricosteroids.

What happened next
Two days after admission and initiation of treatment:
The patient did not improve, abdominal pain worsened.
The mother reported the onset of melena.

DIFFERANTIAL DIAGNOSIS
Sepsis and DIC.Stress ulcer causing GIT bleeding.Mesenteric vascular occlusion as a
complication of hypercoagoulable state of nephrotic syndrome.
![Page 15: Case Presentation Hanan1](https://reader033.vdocuments.net/reader033/viewer/2022051820/55297adc550346752e8b47c9/html5/thumbnails/15.jpg)
![Page 16: Case Presentation Hanan1](https://reader033.vdocuments.net/reader033/viewer/2022051820/55297adc550346752e8b47c9/html5/thumbnails/16.jpg)
Sepsis and DIC
Infection continues to be a problem in patients with nephrotic syndrome, with 70% of the deaths associated with nephrotic syndrome caused by infections, and 50% of these being peritonitis.
Increased susceptibility to infections is related to the proteinuria of nephrotic syndrome and possibly is due to the immunosuppressive medications used to treat it
![Page 17: Case Presentation Hanan1](https://reader033.vdocuments.net/reader033/viewer/2022051820/55297adc550346752e8b47c9/html5/thumbnails/17.jpg)
Sepsis and DIC
Another mechanism for increased susceptibility is the hypogammaglobulinemia in nephrotic syndrome caused by IgG being lost in the urine.
In addition, patients with nephrotic syndrome have diminished opsonization of bacteria as a result of decreased serum levels of factors B (C3 proactivator) and D necessary for the alternative complement pathway
![Page 18: Case Presentation Hanan1](https://reader033.vdocuments.net/reader033/viewer/2022051820/55297adc550346752e8b47c9/html5/thumbnails/18.jpg)
![Page 19: Case Presentation Hanan1](https://reader033.vdocuments.net/reader033/viewer/2022051820/55297adc550346752e8b47c9/html5/thumbnails/19.jpg)
Nephrotic Syndrome: An Acquired Hypercoagulable State
The mechanisms and factors involved in the development of thromboembolic complications in nephrotic syndrome can be attributed to the interplay of two components:
Platelet hyperaggregability Hypercoagulability
![Page 20: Case Presentation Hanan1](https://reader033.vdocuments.net/reader033/viewer/2022051820/55297adc550346752e8b47c9/html5/thumbnails/20.jpg)
Nephrotic Syndrome: An Acquired Hypercoagulable State
Low ATIII: increased clearance .(Antithrombin III levels are lowest when the serum albumin level is less than 2.0 g/dL).
Low functional protein S: increased clearance of free protein S.
Procoagulant serum proteins, including factors I, II, V, VII, VIII, X, and XIII, are increased as a result of increased hepatic synthesis
Increased lipoprotein
![Page 21: Case Presentation Hanan1](https://reader033.vdocuments.net/reader033/viewer/2022051820/55297adc550346752e8b47c9/html5/thumbnails/21.jpg)
How does the case progressed
Abdominal U/S was repeated.
A doppler U/S examination of the splanchnic area was requested.
As well as C.T angiogram for splanchnic area was done.
![Page 22: Case Presentation Hanan1](https://reader033.vdocuments.net/reader033/viewer/2022051820/55297adc550346752e8b47c9/html5/thumbnails/22.jpg)
![Page 23: Case Presentation Hanan1](https://reader033.vdocuments.net/reader033/viewer/2022051820/55297adc550346752e8b47c9/html5/thumbnails/23.jpg)
C.T angiogram
CT image shows gas in portal venous system (blue circle); center image shows absence of contrast in superior mesenteric vein due to thrombosis of this vessel (blue arrow) ; lower image shows extensive pneumatosis intestinalis (red arrows)
![Page 24: Case Presentation Hanan1](https://reader033.vdocuments.net/reader033/viewer/2022051820/55297adc550346752e8b47c9/html5/thumbnails/24.jpg)
How does the case progressed
The ultrasonographic examination revealed the presence of an area of altered echogenicity in the spleen, moderate ascites and turbid fluid.
Doppler U/S revealed the presence of total mesenteric venous occlusion (total occlusion of portal, spleenic, and sup.mesenteric veins ) with a large area of spleenic infarction.
C.T angio revealed the same results, with evidence of venous congestion of the intestine .

![Page 26: Case Presentation Hanan1](https://reader033.vdocuments.net/reader033/viewer/2022051820/55297adc550346752e8b47c9/html5/thumbnails/26.jpg)
WHAT DID WE DO
Surgical deprtement was consulted:
Nothing surgical could be done the case is of poor prognosis.
A bleeding profile was done preliminarily , Low molecular weight heparin was initiated
promptly, The patient was maintained on clexan for 3
weeks then shifted to warfarrin. Follow up by doppler U/S was done/12 hrs
![Page 27: Case Presentation Hanan1](https://reader033.vdocuments.net/reader033/viewer/2022051820/55297adc550346752e8b47c9/html5/thumbnails/27.jpg)
WHAT DID WE DO
The patient started to show progressive improvement.
After 3 weeks the veins started to show recanalization.
Induction of remission for relapse was initiated.
The patient was discharged after 45 days from admission in remission and with recanalization of occluded vessels.
![Page 28: Case Presentation Hanan1](https://reader033.vdocuments.net/reader033/viewer/2022051820/55297adc550346752e8b47c9/html5/thumbnails/28.jpg)
Mesenteric venous thrombosis
Accounts for 5-10% of intestinal ischemia.Causes :
Prothrombotic disorders (antithrombin III protien C, protien S deficiencies) Hypercoagulable states asssocited with
Polycythemia vera, Myeloproliferative disorders, Nephrotic syndrome, Neoplasms.
![Page 29: Case Presentation Hanan1](https://reader033.vdocuments.net/reader033/viewer/2022051820/55297adc550346752e8b47c9/html5/thumbnails/29.jpg)
Acute Mesenteric Venous Thrombosis
Presents as abdominal pain that, early on , is typically out of proportion to physical findings.
Nausea and vomiting are common, and lower GIT bleeding or haematemsis indicating bowel infarction occurs in 15% of cases.
![Page 30: Case Presentation Hanan1](https://reader033.vdocuments.net/reader033/viewer/2022051820/55297adc550346752e8b47c9/html5/thumbnails/30.jpg)
Acute Mesenteric Venous Thrombosis
In patients in whom mesenteric venous occlusion is made a trial of anticoagulation is worthwhile.
Prompt laborotomy, resection of non viable bowel, and anticoagulation with heparin.
The mortality of mesenteric venous thrombosis vary from 20-50%.
Recurrence rates of 20-25 % fall to 13% to 15% if heparin is begun promptly.
