Liver transplantation in patients with common variable immunodeficiency: a report of two cases.

BACKGROUND: Common variable immunodeficiency (CVID) is the most common primary immunodeficiency disease and is a heterogeneous group of antibody deficiency syndromes characterized by hypogammaglobulinemia, recurrent bacterial infections, and frequent autoimmune manifestations. Liver transplantation (LT) is rarely performed in patients with CVID and associated end-stage liver disease. CASE REPORT: We report the successful results of 2 patients who underwent LT with pre-existing diagnosis of CVID. Case 1: A 21-year-old man affected by CVID and HCV-related cirrhosis underwent LT in December 2010 with a 67-year-old deceased donor liver graft. At the time of LT, MELD score was 30. The early post-LT course was characterized by a biliary stricture treated with Roux-en-Y repackaging of the anastomosis. Neither main infections nor acute rejection were detected during the postoperative period. After 43 months follow-up, the patient is alive and well with a histological recurrence of hepatitis C grade 1 and stage 2 according to Metavir staging. Case 2. On March 2013, a 53-year-old woman developed HBV-related fulminant liver failure and underwent urgent LT utilizing a 21-year-old deceased donor liver graft. The postoperative course was characterized by relaparotomy for hemoperitoneum. CMV infection was diagnosed 5 months after LT and resolved after valganciclovir therapy. After 6 months, mild acute rejection was diagnosed and treated with steroids. The patient is currently alive and well. The immunosuppressive regimen was based on Advagraf and early steroids discontinuation in both patients. CONCLUSIONS: LT should not be precluded to patients with CVID and end-stage liver diseases. Immunosuppression has a key role in this category of patients to balance the higher risk of rejection and serious infections.

Outcomes of splenectomy in patients with common variable immunodeficiency (CVID): a survey of 45 patients.

Splenectomy has been used in patients with common variable immunodeficiency disorders (CVID), mainly in the context of refractory autoimmune cytopenia and suspected lymphoma, but there are understandable concerns about the potential of compounding an existing immunodeficiency. With increasing use of rituximab as an alternative treatment for refractory autoimmune cytopenia, the role of splenectomy in CVID needs to be re-examined. This retrospective study provides the largest cohesive data set to date describing the outcome of splenectomy in 45 CVID patients in the past 40 years. Splenectomy proved to be an effective long-term treatment in 75% of CVID patients with autoimmune cytopenia, even in some cases when rituximab had failed. Splenectomy does not worsen mortality in CVID and adequate immunoglobulin replacement therapy appears to play a protective role in overwhelming post-splenectomy infections. Future trials comparing the effectiveness and safety of rituximab and splenectomy are needed to provide clearer guidance on the second-line management of autoimmune cytopenia in CVID.

[Adenocarcinoma of the stomach and neuroendocrine carcinoma of the colon in a 45-year-old male patient suffering from common variable immunodeficiency (CVID) and ulcerative colitis]. / Adenokarzinom des Magens und neuroendokrines Kolonkarzinom bei einem 45-jährigen Patienten mit Common Variable Immunodeficiency (CVID) und Colitis ulcerosa.

Common variable immunodeficiency (CVID) is the most common primary antibody deficient syndrome in adults. Among the broad spectrum of clinical manifestations are recurrent infections, allergies, autoimmune, tumour, pulmonary, liver and gastrointestinal diseases. Here we report the case of a 45-year-old male patient, who has been suffering from ulcerative colitis - likewise recognised as a CVID-associated disease - for many years. He was admitted to our clinic with a rapid progressive reduction of his general condition and a loss of weight. Diagnostic work-up revealed adenocarcinoma of the stomach as well as an undifferentiated neuroendocrine carinoma of the colorectum at the rectosigmoidal junction. Curative resection of the distal stomach and proctolcolectomy were performed. To date, the pathogenesis of the association of many diseases with CVID is still ambiguous. Yet, there is no doubt about the significantly higher incidence of e.g., inflammatory bowel disease or gastric cancer in patients with CVID. Our case highlights that in patients with CVID and obscure deterioration of their general health condition a careful search for especially malignant complications is mandatory although to date there are no precise recommendations for screening.

Immunodeficiency due to chylous dysplasia: diagnostic and therapeutic considerations.

Among primary immunodeficiencies, common variable immunodeficiency (CVID) is defined by an impaired production of immunoglobulins characterized by low levels of plasma immunoglobulins and an altered antibody response. The case reported here was initially interpreted as a CVID. A 20 year old male suffered from diarrhea, weight loss, and malnutrition. Accurate diagnostic assessment uncovered a protein-losing enteropathy. Conventional oil contrast lymphangiography accurately documented the underlying problem and established the appropriate therapeutic approach. The operation consisted of multiple antigravitational ligatures of dilated and incompetent chylous vessels and chylous vessel-mesenteric vein microanastomoses. Serum albumin and leukocyte counts normalized by 1 week after operation and remained stable with time. There were no more episodes of diarrhea, and the patient regained weight. Accurate diagnostic assessment and particularly lymphangiography may be necessary to properly define difficult cases of immunodeficiency due to intestinal protein loss and to plan a corrective therapeutic functional approach.

Non-invasive tracking of human haemopoietic CD34(+) stem cells in vivo in immunodeficient mice by using magnetic resonance imaging.

OBJECTIVE: To assess migration of CD34(+) human stem cells to the bone marrow of athymic mice by using magnetic resonance (MR) imaging and Resovist, a contrast agent containing superparamagnetic iron oxide (SPIO) particles. METHODS: All animal and human procedures were approved by our institution's ethics committee, and women had given consent to donate umbilical cord blood (UCB). Balb/c-AnN Foxn1(nu)/Crl mice received intravenous injection of 1 x 10(6) (n=3), 5 x 10(6) (n=3) or 1 x 10(7) (n=3) human Resovist-labelled CD34(+) cells; control mice received Resovist (n=3). MR imaging was performed before, 2 and 24 h after transplantation. Signal intensities of liver, muscle and bone marrow were measured and analysed by ANOVA and post hoc Student's t tests. MR imaging data were verified by histological and immunological detection of both human cell surface markers and carboxydextrancoating of the contrast agent. RESULTS: CD34(+) cells were efficiently labelled by Resovist without impairment of functionality. Twenty-four hours after administration of labelled cells, MR imaging revealed a significant signal decline in the bone marrow, and histological and immunological analyses confirmed the presence of transplanted human CD34(+) cells. CONCLUSION: Intravenously administered Resovist-labelled CD34(+) cells home to bone marrow of mice. Homing can be tracked in vivo by using clinical 1.5-T MR imaging technology.

Memory B cells in common variable immunodeficiency: clinical associations and sex differences.

Common variable immunodeficiency (CVID) is a heterogeneous syndrome characterized by impaired antibody responses, recurrent infections, inflammatory, autoimmune and malignancy-related conditions. We evaluated the relationship between memory B cell phenotype, sex, age at diagnosis, immunologic and clinical conditions in 105 CVID subjects from one medical center. Reduced numbers of switched memory B cells (cutoff

Common variable immune deficiency and lung transplantation.

We report on a male patient with bronchiectasis secondary to common variable immune deficiency (CVID) receiving lung transplantation. The patient had been diagnosed with CVID many y prior to right-sided single lung transplantation and was receiving appropriate immunoglobulin substitution therapy. He received antithymocyte globulin induction and maintenance triple therapy with cyclosporine, azathioprine and prednisolone. The early post-operative course was complicated by the development of severe acute cellular rejection and organizing pneumonia. Despite immunoglobulin replacement and antifungal prophylaxis and treatment, Aspergillus fumigatus was repeatedly cultured from bronchoalveolar lavage fluid, 18 months after transplantation. The patient died following a protracted period of repeated hospital admissions, 46 months after transplantation. A review of the literature suggests that many CVID patients appear to have had a complicated post-operative course after lung- and other solid-organ transplantation, and highlights the need for the establishment of international registries for transplanted patients with uncommon conditions.

Common variable immunodeficiency patient with large granular lymphocytosis developing extranodal diffuse large B-cell lymphoma: a case report.

Here we describe a Common Variable Immunodeficiency (CVI) patient with large granular (LG) lymphocytosis and systemic non-malignant lymphadenopathy who developed diffuse large B-cell lymphoma of the stomach. This is the first report of gastric high-grade lymphoma with widespread lymphadenopathy in a patient with LG lymphocytosis associated with CVI.

Heart lung transplantation in a patient with end stage lung disease due to common variable immunodeficiency.

The case history is presented of a patient with common variable immunodeficiency in whom heart lung transplantation has been carried out with success. Transplantation was the only long term therapeutic option in this patient due to the progressive respiratory failure resulting from bronchiectasis, emphysema, and granulomatous lung disease.

Lung Transplantation in patients with systemic diseases: an eleven-year experience at Papworth Hospital.

BACKGROUND: The presence of a systemic disease has traditionally been considered a contraindication to lung transplantation. METHODS: We present a retrospective review of 19 patients undergoing lung transplantation for end-stage pulmonary disease associated with a systemic illness since 1984. There were 11 male and 8 female patients, aged from 23 to 59 years (median 43 years) with end-stage pulmonary involvement by sarcoidosis (11 patients), Langerhan's cell histiocytosis (three patients), systemic vasculitis (four patients: three with systemic lupus erythrematosis, one with Churg-Strauss), and common variable immunodeficiency (one patient). Ten patients received a heart-lung transplant, and eight patients received a single lung transplant. One patient underwent single lung transplantation after an earlier heart-lung transplant. RESULTS: The 30-day mortality was 5.3%. Nine patients died overall. Two of these had systemic lupus erythrematosis with anticardiolipin antibodies and died from complications of their underlying vasculitis. The mean 1- and 2-year actuarial survivals for all patients were 71% (standard error +/- 10.8%) and 64% (standard error +/- 11.9%), respectively. All patients surviving longer than 3 months achieved an improvement in functional status to New York Heart Association class I or II, and a significant increase occurred in mean forced expiratory volume in 1 second and forced vital capacity. Disease recurrence without clinical significance occurred in two patients with sarcoidosis. Of the nine patients who died, seven had autopsies and none showed evidence of disease recurrence in the lungs. CONCLUSIONS: Patients with systemic diseases can be considered for lung transplantation and each case should be judged on its individual merits. However, patients with systemic lupus erythrematosis (particularly when associated with anticardiolipin antibodies) should probably not be offered lung transplantation because they are likely to develop further complications of their underlying vasculitis.
