A method is described to assess antigenic cross-reactivity between soluble immune complexes precipitated from sera with polyethylene glycol. The precipitated complex from one serum was dissociated in acid and used to coat a plastic cup. Radioiodinated complexes from another serum were dissociated in the cup, neutralized and allowed to reassociate overnight. The binding of the labelled complex was used to measure the cross-reactivity between the complexes. Using this technique, complexes from a group of patients with haematuria and hypertension have been found to share an antigen, and a different antigen was found in patients with bullous pemphigoid. The participation of rheumatoid factors in the cross-reactions is unlikely, and no cross-reactivity of either group was found with sera from patients with rheumatoid arthritis.

Captopril is commonly prescribed to patients with hypertension and congestive heart failure. Adverse dermatological reactions have been reported in about ten percent of patients receiving captopril. This case report describes a 77-year-old white woman who developed bullous pemphigoid associated with the use of captopril. The patient presented with bullous eruptions localized on the palms of both hands about 50 days after captopril 25 mg bid was started. Biopsy report was consistent with bullous pemphigoid. Captopril therapy was discontinued and the lesions healed after oral corticosteroid therapy was initiated.

Quinidine-induced lichenoid photodermatitis was definitely isolated by Berger and Sesody in 1982. We had an opportunity to observe 4 cases of this striking clinical condition and encountered some particularities. Our patients (2 men and 2 women) were 60, 64, 81 and 68 years old respectively. All had a previous cardiovascular history; diabetes was also present in patient No. 2, and hypertension in patient No. 4. All patients were taking other drugs. The first patient presented with a 4-year old lichenoid eruption on the hands, associated with some degree of follicular keratosis. The second and third patients had a mixture of mainly lichenoid lesions on sun-exposed areas, but eczematous and desquamative lesions were also encountered. The fourth patient had typical lichenoid photodermatitis with occasional bullae on the arms and legs. In all patients the disease appeared or worsened in the Summer. It disappeared rapidly in 3 cases upon withdrawal of quinidine (patients No. 1 and 2) or hydroquinidine (patient No. 3), but it lasted longer in patient No. 4, with pigmented sequelae. Histological examination of the skin was consistent with a lichenoid eruption in all cases. However, an immunopathological study revealed a pemphigoid-like pattern in patients No. 1 and 2, and ovoid bodies more suggestive of lichen planus in patient No. 4. Photobiology was not performed. A review of the literature showed that the terms "lichen planus", "lichenoid", "lichenification" or "violaceus hue" were frequently encountered, and we suggest quinidine as one of the most common agents of lichenoid reaction.(ABSTRACT TRUNCATED AT 250 WORDS)

We investigated skin diseases associated with mucocutaneous Candida infection by analyzing the clinical records of 44695 in-patients of the department of dermatology of Kiel. For more than eighty skin diseases the relative risk (RR) was calculated by age-and sex-adjusting methods. 1996 patients demonstrated a mucocutaneous candidosis, 14.8% of them being hospitalized because of extensive Candida infection. In patients with dermatomyositis, bullous pemphigus, tinea inguinalis, and condylomata acuminata a Candida infection was observed more than threefold than expected. Furthermore, patients with urticaria, folliculitis, and bullous pemphigoid demonstrated candidosis more than twice as often as control patients. In addition, patients with erysipelas, acne, psoriasis, and atopic dermatitis showed a candidosis significantly more often (RR between 1.3 and 1.6). Some internistic maladies were investigated, too. In patients presenting with diabetes mellitus, heart-insufficiency, hypertension, chronic tonsillitis, and urinary tract infection a mucocutaneous Candida infection was significantly increased.

Immunobullous diseases usually develop spontaneously, but drug-induced bullous disease develops in a small subgroup of patients. We examined a patient in whom bullous pemphigoid developed after she received enalapril for treatment of hypertension. IgG antibody directed against a 230 kd antigen was identified. The eluted IgG autoantibody was shown to bind to the basement membrane zone on split skin. This study demonstrates that drug-induced bullous pemphigoid autoantibody in this patient was directed against the same antigen as the spontaneous bullous pemphigoid antigen.

A 47-year old patient who had been suffering from hypertension and chronic renal failure for many years developed progressive extensive haemorrhagic erosions of the mouth within 3 months and less severe erosions of the genital and nasal mucosa. Additionally, subcutaneous haematomas developed spontaneously. Laboratory investigations demonstrated circulating antibodies against factor VIII while direct and indirect immunofluorescent microscopy showed discrete tissue-bound and circulating IgG reactive with the epidermal basement membrane in a pemphigoid-like fashion. Immunoblot analysis of the patient's serum revealed an "atypical" IgG reactivity against a central portion of the extracellular domain of the BP180 antigen. These findings were unexpected, since the clinical aspect showed striking resemblance to (paraneoplastic) pemphigus. The patient developed life-threatening complications. Eventually, reduction of circulating autoantibodies by a combination of plasmapheresis and subsequent immunosuppressive therapy led to a stable remission of both autoimmune bullous skin disorder and acquired haemophilia.

Pemphigoid gestationis is a gestational skin disease usually appearing between the 28th and the 32nd week of amenorrhea. It is a rare vesiculobullous skin disease and the eruption is located around the umbilicus. The diagnosis is made with clinical symptoms but mainly on histologic examination (after skin biopsy) and direct immunofluorescence. One of the main complications is the rate of recurrence. The main treatment is based on topical corticosteroids. The effects of the pemphigoid gestationis are maternal (preterm labor), fetal (intrauterine growth retardation) and neonatal (bullous disease). We report a case of pemphigoid gestationis associated to a gestational hypertensive disorder and we try to rely on both entities.

Several cases of psoriasis associated with bullous disorders have been reported, and it is clearly recognized that bullous pemphigoid (BP) is the most common bullous disorder observed in association with psoriasis, especially after ultraviolet (UV)B and psoralen UVA therapy. Moreover, other medications have been repeatedly reported to induce bullous diseases, especially pemphigus vulgaris. We report for the first time a case of BP possibly induced by losartan, an angiotensin II antagonist, in a patient with a severe psoriatic background. Angiotensin II type 1 receptor antagonists belong to a new class of drug for hypertension or congestive heart failure with established efficacy and few side-effects. Coexistence of psoriasis vulgaris with bullous diseases represents also a difficult therapeutic challenge. This rare case of psoriasis and generalized BP triggered by a sartan drug was treated with rituximab and etanercept.

A 73-year-old woman with a 50-year history of psoriasis was referred to our clinic with a 4-month duration of tense bullae on erythematous base and erosions localized on her lower extremities and torso (Figure 1A). Neither the oral nor the ocular mucosa had been involved. The lesions were intensively pruritic, significantly affecting the quality of her life. At the time of the examination, the patient presented with psoriatic plaques with adherent scales confined on the scalp (Figure 2A). According to the patient's history, her limited psoriasis was partially controlled with occasional topical medications (topical corticosteroids, calcipotriol, and tar shampoo). She also had insulin-dependent diabetes mellitus, asthmatic bronchitis, and partially controlled hypertension with hyperlipidemia. A biopsy specimen was taken from lesional skin on her feet, and a histological examination showed a subepidermal blister with an inflammatory cell infiltrate in the upper dermis. No drugs were incriminated, and diagnosis of bullous pemphigoid was confirmed by Western immunoblotting of serum. Laboratory investigation revealed mild thrombocytopenia of 110,000/mm(3), cholesterol 279 mg/dL, and triglycerides 210 mg/dL. The patient could not tolerate prednisolone and cyclosporine because of hypertension and diabetes, or azathioprine because of the mild thrombocytopenia; she did not consent to receiving biologics. Mycophenolate mofetil (MMF) was then considered a choice. The patient agreed, and she was initially administered 1000 mg/d. After 2 weeks, the dosage increased to 1000 mg twice a day because of the formation of new blisters. Within 8 weeks of treatment with MMF 2000 mg/d, marked improvement was observed and her pruritus resolved. Complete remission of bullous pemphigoid and psoriasis was achieved within 3 and 4 months, respectively. Routine laboratory studies were performed before treatment and every month during therapy, and MMF was tolerated without side effects. The treatment was continued for 6 months with no subsequent relapse of the dermatoses (Figure 1B and Figure 2B).

To study associations of bullous pemphigoid (BP) with internal diseases, we conducted a retrospective case control study assessing the frequency of selected diseases - diabetes mellitus, neurological diseases, malignant tumors, benign prostate hyperplasia, hypertension and ischemic heart disease in patients with BP. 89 patients with BP, whose data were retrieved from the register of the Centre of bullous diseases from the period of 1991-2006, were matched with 89 controls of the same age and gender, recruited from patients treated for other skin diseases. The frequency of internal diseases at the time of the onset of BP was evaluated by unconditional logistic regression adjusted for age and gender and maximum likelihood test for contingency tables. Neurological disease was found in 42.7% of the patients and in 19.1% of controls. This difference was statistically significant (p value = 0.001). Moreover, regression analysis has shown that patients with neurological disease in the age group >or= 80 years have significantly higher risk of pemphigoid than patients without neurological disease (odds ratio 10.55; 95% confidence interval 2.68 to 41.49). Most frequent were cerebral stroke in men and dementia in women. For other diseases and other age groups, no statistically significant influence was found.
