Sterile splenic abscesses in systemic Weber-Christian disease. Unique source of abdominal pain

Pfeifer-Weber-Christian Disease: A Case Report and Review of Literature on Visceral Involvements and Treatment Choices

Pfeifer-Weber-Christian disease (PWCD) is a rare idiopathic disease characterized by lobular panniculitis of adipose tissue with systemic symptoms and multiple organ involvement. Even though the systemic involvement is rare, it is life-threatening and represent a treatment challenge for the clinicians. We report a case of PWCD characterized by hepatic, hematologic, and renal involvement, with good response to mofetil mycophenolate and prednisone treatment. A 47-year-old female presented several months’ history of painful subcutaneous nodules, fever and lymphadenopathy with recent appearing of microcytic hypochromic anemia, leucopenia with neutropenia, and increase in transaminase. Skin biopsy showed lobular panniculitis with lymph-histiocytic and neutrophilic infiltrates with necrosis of adipocytes. A combination therapy of corticosteroid with mofetil mycophenolate was effective. Moreover, we discuss the clinical manifestation and the therapeutic choices in PWCD, from classical immunosuppressive drugs to new biotechnological agents, and we provide a comprehensive review of the available literature.

Is splenectomy a treatment option for aseptic abscesses in patients with Crohn's disease?

The most common extraintestinal manifestations of Crohn's disease concern joints, skin, and eyes; however other organs such as liver, pancreas, kidneys, heart, lungs or brain can also be affected. Aseptic abscesses are an emergent entity in patients with inflammatory bowel disease and despite medical treatment the surgical approach may represent an alternative therapy. We report a case of a young woman with splenic aseptic abscesses as complication of Crohn's disease. After steroid sparing and antibiotic failure the patient underwent successful splenectomy.

Aseptic abscesses: a study of 30 patients with or without inflammatory bowel disease and review of the literature

Aseptic abscesses (AA) are characterized by deep, sterile, round lesions consisting of neutrophil that do not respond to antibiotics but improve dramatically with corticosteroids. We report the clinical, laboratory, and radiologic characteristics and the associated conditions of 29 patients from the French Register on AA plus 1 patient from the Netherlands.The mean age of patients at AA diagnosis was 29 years (SD = 14). The main clinical manifestations of AA were fever (90%), abdominal pain (67%), and weight loss (50%). Duration of symptoms was 4.7 months on average until abscesses were discovered. The abscesses involved the spleen in 27/29 patients (93%; the thirtieth patient had a personal history of splenectomy after a trauma). In 7 they were unifocal and in the others they were multifocal, involving in addition the abdominal lymph nodes in 14 (48%), liver in 12 (40%), lung in 5 (17%), pancreas in 2 (7%), and brain in 2 (7%). They were not splenic in 3, including 2 with abdominal lymph nodes and 1 with superficial lymph nodes and testicle and lung involvement. Twenty-two patients (70%) had elevated white blood cell and neutrophil count; antineutrophil cytoplasmic autoantibodies with a perinuclear, cytoplasmic or atypical pattern (negative for antiproteinase 3 and negative for antimyeloperoxidase except for 1) were positive in 21% of the 24 patients tested. Twenty-one patients had inflammatory bowel disease (IBD), which preceded the occurrence of abscesses in 7, was concomitant in 7, and appeared secondarily in 7. Six patients had neutrophilic dermatosis (20%), 3 had relapsing polychondritis as an associated condition, and 3 others had monoclonal gammopathy of undetermined significance. Three patients had no associated condition. Splenectomy was performed in 15 (52%) patients. All patients received steroid therapy. Thirteen (43%) were given additional immunosuppressive therapy, 1 immediately and the others after a relapse, of whom 3 were also treated by anti-tumor necrosis factor-alpha agents. Mean follow-up was 7 years. Eighteen (60%) patients experienced 1 or several relapses, but there was no death related to AA. Relapses occurred on immunosuppressive therapy in 2 patients and off immunosuppressive therapy in the others while corticosteroids were being tapered. We surveyed the literature and analyzed 19 additional cases. AA is an emergent and probably underrecognized entity. It represents an apparently noninfectious inflammatory disorder involving neutrophils that responds to corticosteroid therapy. AA mainly affects patients with IBD but also affects those with other conditions, or with no other apparent disease.

Abscess of the spleen

Splenic abscess is a rare disease but with increasing frequency. The authors present 9 patients with splenic abscess treated at the Institute of Digestive System Diseases, Clinical Centre of Serbia, in a period from January 1, 1986 to May 15, 2004. Splenic abscess was the complication of septic endocarditis in 4, trauma in 2, dental infection in 1, while in 2 cases it was the complication of chemotherapy in myeloproliferative disorders. All 9 patients had fever, 7 - abdominal pain, 4 - left shoulder pain, and 1 patient had nausea and vomiting. Higher white blood count was found in 6 patients, pleural effusion in 4, elevated left hemidiaphragm in 1 and basal pneumonia in 1 patient as well. Ultrasonography and CT were the most reliable diagnostic procedures. CT was superior in diagnosis of multiple small abscesses. Culture of the pus recovered the Enterococcus in 3 cases, Streptococcus a hemolyticus in 1, Staphylococcus epidermidis and Candida albicans in 1, Staphylococcus aureus, E. Coli and Candida albicans in 1, Staphylococcus aureus and Salmonella enteritidis in 1 case. Eight patients underwent splenectomy and 1 was cured by combined antibiotics in high doses. One patient died postoperatively due to septic endocarditis that had been present before surgery. The authors believe that splenectomy and antibiotics administered according to drug susceptibility test as well as management of underlying disease are the method of choice for splenic abscess treatment. Conservative antibiotic treatment is indicated in selected cases only.

Splenic Abscess: Report of Six Cases and Review of the Literature

Splenic abscesses are rare but appear to be increasing in frequency. Recent advances in radiologic techniques have affected the diagnosis and management. The purpose of this study was to evaluate these effects. The medical records of one institution were retrospectively reviewed and six cases of splenic abscesses seen between 1989 and 1999 were identified. All patients had predisposing conditions with metastatic hematogenous infection in three and one each with trauma, immunodeficiency, and a contiguous site of infection. Fever was present in all patients with chills and vomiting in five and three patients, respectively. Left upper quadrant tenderness appeared in four patients and leukocytosis was found in every patient except one with the acquired immunodeficiency syndrome. Chest roentgenograms were abnormal in five patients with a left pleural effusion most common. Ultrasound revealed the defect in both patients it was utilized in and computed tomography was diagnostic in all cases. The causative organisms were anaerobes in two cases and Candida albicans, Streptococcus viridans, Escherichia coli, and Citro-bacter freundii each present in one case. Radiology guided percutaneous drainage was attempted in four patients but was only successful in one. Splenectomy with antibiotics was curative in the remainder with a 100 per cent survival. These data suggest that percutaneous drainage may be appropriate for certain patients initially, but the high failure rate demonstrates that splenectomy remains the standard treatment.

Systemic Weber-Christian disease

BACKGROUND

Weber-Christian disease is a controversial entity that histologically presents as a lobular panniculitis. A systemic variant of this disorder, in which visceral fat is affected, has been reported.

OBJECTIVE

A 29-year-old woman with Weber-Christian disease developed a rapidly enlarging abdominal mass during hospitalization for a flare of her skin condition. The mass resolved spontaneously. Radiographic studies demonstrated a mesenteric cyst, which was thought to represent involvement of mesenteric fat by Weber-Christian disease.

CONCLUSION

The appearance of an abdominal or pelvic mass in a patient with Weber-Christian disease may be due to visceral involvement by the inflammatory process.

Splenic abscesses from 1987 to 1995

BACKGROUND

Isolated splenic abscesses is an uncommon clinical entity that is being increasingly recognized as a cause of intraabdominal sepsis in a wide variety of clinical situations, and involving a wide range of organisms. The increasing incidence of immunosuppressed states in this decade due to the use of chemotherapy for oncology, immunosuppression therapy for transplantation, and acquired immune deficiency syndrome, has changed the disease pattern of splenic abscesses.

METHOD

Data from 287 cases reported in the English literature between 1987 and 1995 were collected, analyzed, and compared with two previous reviews of cases reported before 1987.

RESULTS

Staphylococcus, Salmonella, and Escherichia coli are the most common organisms cultured. Immunosuppressed states were present in 33.5% of cases, with intravenous drug abuse and acquired immune deficiency syndrome accounting for half these cases. Computerized tomography and ultrasonography are diagnostic, with a sensitivity of 92.2% and 87.2%, respectively. Nonoperative management has a success rate of less than 65%, but salvage splenectomy does not increase mortality compared with splenectomy as initial therapy.

CONCLUSIONS

Splenic abscesses are increasingly recognized with immunosuppressed states. Percutaneous radiologically guided drainage may be suitable in some cases, but splenectomy with appropriate antibiotics is the definitive treatment.
