Linear IgA disease (LAD) is a rare acquired autoimmune bullous disorder, characterized by linear deposition of IgA along the dermoepidermal basement membrane zone. The clinical presentation of LAD consists of vesiculobullous lesions affecting the skin and mucosal surfaces. The present case report presents a rare presentation of this vesiculobullous disorder. Although more than 50% of LAD patients present with oral lesions, there are few reported cases of involvement of the mouth as the sole manifestation. A 79-year-old female presented with a sore mouth and erosions affecting the palate. The symptoms resolved following the provision of mycophenolate, an antiproliferative immunosuppressant which has not previously appeared to have been reported in the long-term successful management of linear IgA disease limited to the mouth. We found that mycophenolate is a useful adjunct to the successful treatment of oral linear IgA when the uses of other immunosuppressants are contraindicated.

Conversion from cyclosporine (CsA) to tacrolimus (TRL) remains challenging in the daily routine due to individual variations in blood concentrations (pharmacokinetics, PK), pharmacodynamics (PD) and in interactions on plasma mycophenolic acid (MPA) concentrations. Therefore, we used our PD assays of lymphocyte function to monitor the conversion of CsA to TRL in heart (HTx) and lung (LTx) transplant recipients.. Patients (six HTx, two LTx) were converted from CsA to TRL because of gingival hyperplasia. All patients were treated with 6 mg BID TRL 24 hours after the last CsA dose and received mycophenolate mofetil BID cotherapy. PK measurements of CsA, TRL, and MPA were done by EMIT. Expression of cytokine production (IL-2, TNF-alpha), lymphocyte proliferation (PCNA), and activation (CD25) was assessed by FACS.. TRL concentrations increased from day 1 to 3, but did not alter MPA concentrations, which were comparably high to MPA concentrations in combination with CsA (day 0). Compared to CsA therapy, increased TRL concentrations did not further inhibit PCNA expression, inhibited CD25 expression less on days 1 and 2 and equally high on day 3, but inhibited expression of IL-2 and TNF-alpha significantly higher on days 2 and 3 (P < .05).. This study shows that monitoring PD of lymphocyte functions after conversion from CsA to TRL in HTx and LTx recipients revealed differences of inhibition of lymphocyte functions. Monitoring PD of lymphocyte function may provide insights in drug interactions of immunosuppressive combination therapy and may help to tailor immunosuppression to avoid toxicity and to enhance efficacy.
