Introduction

Churg Strauss syndrome (CSS) (allergic granuloma­tosis and angiitis) is a systemic disorder characterized by asthma, transient pulmonaiy infiltrates, hypereosinophilia and a systemic vasculitis1-3. CSS is a rare disease; however, this syndmme has been reported with increasing frequency in recent years2. The organs most evidently involved clinically are the heart, lungs, kidney, gut, skin and peripheral nerves3.
We present a case of Churg-Strauss Syndrome compli­cated by intestinal perforation and intracerebral hemorrhage, alongwith a review of literature regarding gastrointestinal involvement in this condition.

Case History

A 45 years old gentleman was admitted to the hospital beóause of headache, dysphasia and right hemiparesis for one day. He had been well until two years ago when he began experiencing paroxysmal attacks of wheezing. A total white count done at that time was 18x109/L with 73% eosinophils. He was prescribed inhaledbmnchodilators and steroids,yet he continued to have episodes of breathlessness and wheezing during the next two years.One month prior to admission to the hospital he began complaining of intensejoint pain, dyspnoea and weakness in his hands. He also developed a papular rash over both feet A complete blood picture showed the white blood count to be 30.9x109/L with 64% eosinophils. A skin biopsy was taken which showed leukoclastic vasculitis (Figure).

He was treated with prednisolone for one week following which his symptoms, particularly his wheezing improved.
At the time of admission, he was conscious but disorientated in time, place and person. He was afebrile, pulse was 90/minute and blood pressure was 140/80 mmHg. Neurological examinationshowed dysphasia and upper motor neuron palsy of the seventh and twelfth cranial nerves on the right side. There was right hemiparesis alongwith bilateral wrist drop with wasting of small muscles of both hands. There also was evidence of Raynaud’s phenomenon. Examination of all other systems was unremarkable. His hemoglobin was 14.4 g/dl and white cell count was 9x109fL with 70% polymorphs, 18% lymphocytes and 12%eosinophils. A CT scan showed an intracerebral bleed in the left temporal region. Subsequently his neurological status improved over the next few days. The nerve conduction study was consistent with mononeuritis multiplex. His anti-neutrophilic cytoplasmic antibodies (ANCA) was positive while the chest x-ray was normal. He was treated with cyclophosphaniide and steroids.
On the sixth day of admission, he suddenly developed severe abdominal pain which gradually increased. He became hypotensive and developed signs of generalized peritonitis. An X-ray film of the abdomen showed pneumoperitoneum. A laparotomy was performed and per operatively a solitaiy punched out perforation 135 cm from the duodenojejunal flexure was seen. Wedge resection and primary closure of the perforation was done.
Histopathology of the gut wall taken from the perfora­tion showed heavy infiltration of acute inflammatory cells.
His post-operative course was uneventful and he was discharged on Predmsolone and Cyclophosphamide. Six months post-operation, he had a grand-mal seizure, while coming back from work and was started on Phenytoin. Till the writing of this report it has been over 2 years since the operation and he has remained asymptomatic on 5 mg Prednisolone.

Discussion

The original description of this disorder as a distinct clinicopathological entity was done by Churg and Strauss in 19492,3. Since then, several reports of CSS have appeared in the literature. Although Lanham et al1 reviewed 154 cases with CSS in 1984, this remains a rare disease.
Lanham et al noted 3 criteria for the diagnosis of CSS; asthma peak peripheral blood eosinophil count in excess of 1 .5x109/L and the characteristic systemic vasculitis involving 2 or more extrapulmonary organs. The presentation of this syndrome is highly variable and its clinical manifestations are protean5. CSS can involve a number of organs including the cardiovascular, pulmonary, gastrointestinal, nervous, renal and musculoskeletal system6,7. Cardiac disease is recorded as the major cause of death in CSS. It can present as pericarditis, cardiac failure or merely an abnormal electrocardiogram. Pulmonaiy disease may manifest as infiltrates which are generally transient. Pulmonary hemorrhage is an important complication. Pleural effusion can occur and contains large amount ofeosinophils. Renal disease occurs in the majority of the patients and is characterized by focal segmental glomeru­lonephritis, but renal failure is relativ ely uncommon. The usual lesion in CNS involvement is a mononeuritis multiplex. although a diffuse symmetric neuropathy can occur. Cerebral infarction, although rare is the second most common cause of death. Rash is a common feature, appearing as palpable purpura, erythema orurticaria. Arthritis orarthralgia may also be seen.
Our patient demonstrates several important features of CSS. He initially had adult onset of asthma and peripheral eosinophilia. Later on he had evidence of a systemic disease involving the joints, skin, central nervous system and gastro­intestinal tract.
Gastrointestinal symptoms in CSS include abdominal pain, bloody stools, diarrhoea and nausea and vomiting. Although gastrointestinal symptoms are commonly seen, the literature contains few detailed descriptions of the gastrointes­tinal lesion2. The gastrointestinal tract may be involved in 20% of the patients with CSS and typically results in intestinal inflammation, ulceration, perforation or hemorrhage8.
In a review of 154 cases reported in the English literature, Lanharn found abdominal pain as a common symptom (59% of all cases) which reflected bowel perfora­tion, peritonitis, intestinal obstruction, mesenteric vasculitis or cholecystitis6. In a large series of 165 patients which included both Churg Strauss syndrome and Polyarterities Nodosa patients9, 52 (31%) had abdominal signs and symp­toms. The most severe episodes of abdominal pain were due to peritonitis (9 cases), duodenal ulcer (3 cases), intestinal infarction (1 case) and unexplained pain (1 case). while 11 patients presented with gastrointestinal hemorrhage. In the Japanese literature there have been 21 cases of lesions in the gastro-intestinal tract in association with CSS. These lesions were in the form of multiple ulcers located in the stomach, small intestine and the colon. Twelve of these 21 cases presented as a gastrointestinal perforation. The small intestine was the most common site of involvement and the most frequently perforated. Most of the cases in the literature were not diagnosed until surgery or death2.
Other gastrointestinal manifestations of CSS reported in the literature are chronic active hepatitis, chronic ulcerative colitis10, intrahepatic duct perforation caused by hepatic aneurysm rupture11 and a calculous cholecystitis12. Schoret­santis et al have recently reported a case of Churg-Strauss syndrome where severe mesenteric intestinal ischemia lead to small bowel necrosis13. This patient underwent five laparoto­mies for resection of small bowel and survived.
The case that we have described fits most likely to the diagnosis of Churg Strauss Syndrome (CSS). Abdominal pain and intestinal ulceration and perforation are not rare. If physicians and surgeons keep this condition in mind and accurate and reliable histopathological reports are available, we have no doubt that more of such cases would be diagnosed.In tropical countries eosinophilia should not be labeled as only due to parasitic and allergic causes. Other less common causes like Churg strauss syndrome and Polyarteritis Nodosa should also be considered.
