Childhood immunobullous disease following a second organ transplant

The relationship between bullous pemphigoid and renal disease and related treatments: a review of the current literature

INTRODUCTION

Bullous pemphigoid (BP) is the most common autoimmune subepidermal blistering disorder in older adults. There is increasing evidence that BP has connections with renal diseases, such as glomerulopathy and neoplasm; it is also linked to the receipt of renal replacement therapy.

AREAS COVERED

In this review, we summarize the current evidence that BP is a comorbidity of common renal diseases. Furthermore, our exploration of the characteristics and possible mechanisms underlying these connections provides insights that may facilitate the prevention, diagnosis, and management of BP.

EXPERT OPINION

There is mounting proof that BP is not just a skin immunological disorder but rather a systemic immune-mediated illness. Quantities of case reports focused on BP as a renal disease comorbidity and the coexistence of them is not accidental. However, the underlying mechanisms are still needed to be investigated. Clinicians should be alert to the comorbidities in order to facilitate effective treatment and improve patient prognosis.

New diagnosis of bullous pemphigoid after withdrawal of immunosuppressive therapy in a failed renal transplant recipient on hemodialysis

The occurrence of the autoimmune blistering disease, bullous pemphigoid (BP), in patients with failed renal allograft is rare and the few reported cases suggest various provocative factors without reaching a consensus. Here we report the case of a patient presenting with bullous lesions soon after the complete discontinuation of immunosuppressant therapy following renal allograft failure. Skin biopsy confirmed the diagnosis of BP. Administration of systemic corticosteroid controlled the occurrence of BP lesions in our patient. Increased clinical suspicion is warranted in cases of patients with renal transplant failure, since withdrawal of the immunosuppressant therapy could lead to unmasking the underlying autoimmune skin disease.

Bullous pemphigoid in a renal transplant recipient: a case report and review of the literature

Bullous pemphigoid (BP) is an autoimmune disease with chronic, recurrent bullous eruptions. BP has been reported to be associated with drugs, physical stimuli, malignancies, and immune abnormalities. Its association with renal transplant is rare and only four cases have been reported. We present a case of BP in a 52-year-old man with chronic hepatitis B and C infection who underwent a cadaveric renal transplant 13 years earlier. His graft was still functioning well when BP appeared. The occurrence of BP in our patient might be a result of drugs (furosemide or tacrolimus), viruses, or renal allograft. As the patient was receiving regular T-cell immunosuppressant therapy, his BP lesions were recalcitrant to corticosteroid treatment. We discuss the pathogenesis and treatment of such patients.

Infectious, malignant, and autoimmune complications in pediatric heart transplant recipients

OBJECTIVE

To review clinical courses of pediatric heart transplant survivors after 5 years from transplantation for infections, lymphoproliferative, and autoimmune diseases.

STUDY DESIGN

A total of 71 patients were examined in 2 groups, infant recipients (underwent transplant <1 year of age, n = 38) and older recipients (underwent transplant >1 year, n = 33). All patients received comparable immunosuppression. Calculated occurrence rates were reported as means per 10 years of follow-up with SEs. Differences were examined by using Poisson regression.

RESULTS

Infant recipients had significantly higher (P < .001) occurrence rates of severe (mean, 2.04 +/- 0.5) and chronic infections (mean, 4.58 +/- 0.67) compared with older recipients (means, 0.37 +/- 0.19 and 1.87 +/- 0.70, respectively). Types of infections were similar to those in the general population with extremely rare opportunistic infections; however, they were more severe and resistant to treatment. Autoimmune disorders occurred at a frequency comparable with lymphoproliferative diseases and were observed in 7 of 38 infants (18%). Most common were autoimmune cytopenias.

CONCLUSIONS

Infant heart transplant recipients who survive in the long term have higher occurrence rates of infections compared with older recipients. Autoimmune disorders are a previously unrecognized morbidity in pediatric heart transplantation.

Acquired Glanzmann's thrombasthenia as part of multiple-autoantibody syndrome in a pediatric heart transplant patient

Although advances in immunosuppressive therapy have allowed prolonged patient survival, immune dysregulation observed in these patients has increased. We report an 11-year-old female heart transplant recipient in whom Glanzmann thrombasthenia was identified as part of a "multiple autoantibody syndrome" manifesting sequentially as autoimmune hemolytic anemia, thrombocytopenia, and neutropenia.

Case report: Oral pemphigus vulgaris with multiple oral polyps in a young patient

A rare case of oral pemphigus vulgaris is presented, which developed initially in a 9-year old Jordanian male. The disease was not well controlled with immunosuppressive therapy and was complicated by the development of multiple oral polyps approximately one year after the onset of symptoms. These lesions were smooth, painless and located particularly on the upper labial gingiva, the labial and buccal mucosae and the tongue. Disease activity continued for approximately nine years until the patient was referred to an oral medicine specialist. Histological examination of the polyps revealed exuberant granulation tissue. Adjustment of the steroid dosage lead to resolution of the oral symptoms and the polyps reduced in number and in size. This case highlights the occurrence of pemphigus vulgaris in young patients, illustrates a rare complication of persistent ulcero-inflammatory disease and emphasises the importance of specialist referral in the management of oral disease.
