To define the clinical picture and course of the autosomal recessive disease called autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), we report data from our 10-month to 31-year follow-up of 68 patients from 54 families, now 10 months to 53 years of age. The clinical manifestations varied greatly and included from one to eight disease components, 63 percent of the patients having three to five of them. The initial manifestation was oral candidiasis in 41 patients (60 percent), intestinal malabsorption in 6 (9 percent), and keratopathy in 2 (3 percent). All the patients had candidiasis at some time. The earliest endocrine component appeared at 19 months to 35 years of age. Hypoparathyroidism was present in 54 patients (79 percent), adrenocortical failure in 49 (72 percent), and gonadal failure in 15 (60 percent) of the female patients greater than or equal to 13 years of age and 4 (14 percent) of the male patients greater than or equal to 16 years of age. There were multiple endocrine deficiencies in half the patients. From 4 to 29 percent of the patients had periodic malabsorption, gastric parietal-cell atrophy, hepatitis, alopecia, vitiligo, or a combination of these conditions. Dental-enamel hypoplasia and keratopathy were also frequent but were not attributable to hypoparathyroidism. In the patients whose initial manifestation (other than candidiasis) was adrenal failure, the other components developed less often than in the remaining patients. We conclude that the clinical spectrum in patients with APECED is broad. The majority of patients have three to five manifestations, some of which may not appear until the fifth decade. Therefore, all patients need lifelong follow-up for the detection of new components of the disease.

In this study the data on 200 patients affected by various features of lichen planus (LP) are reported. All subjects were in-patients of the Department of Dermatology, Bari, from 1973 to 1988. In 87% of cases the disease appeared as lichen tuber planus, and in 9% there was involvement of mucous membranes. Equal involvement of sex incidence has been found, and the patients were middle-aged (mean, 47 years). The lesion were not subsided in about 10% of cases. Associated fortuitous skin conditions were mainly alopecia areata and vitiligo. In addition, LP has been observed in association with diabetes (8%) and hepatic diseases (10%). These last values could appear relevant, but in our region, Apulia, both diabetes and hepatitis, and especially B-hepatitis, are very frequent diseases. Our clinical follow-up did not allow to consider LP as a symptom of other subsequent organic diseases.

Persistent viral infections have been postulated to be trigger factors for the development of autoimmune disease. We report the development of vitiligo in four patients with human immunodeficiency virus (HIV)-related conditions and in one patient with hepatitis who later developed both psoriasis and acquired immunodeficiency syndrome (AIDS). Other common features were hepatitis and multiple other viral infections. Ribavirin was associated with repigmentation in one patient. Vitiligo may be an example of an autoimmune disease triggered by viral infection in a genetically predisposed host.

Sixty-five patients with histologically proven chronic active hepatitis of unknown cause but associated with the antiliver/kidney microsome antibody type 1, confirmed by immunofluorescence and immunoprecipitation, were selected as forming a special entity. This disease was found to be rare with a prevalence of 5/1,000,000. The female to male ratio was 8:1. The condition occurred at all ages but was most common between the ages of 2 and 14 years. In 22 of the 65 cases, the hepatitis was associated with an autoimmune disease, most commonly insulin-dependent diabetes, autoimmune thyroid disease and vitiligo. The same autoimmune diseases were present in first-degree relatives from seven families. In 36 cases, the onset of disease resembled acute viral hepatitis. Serum biochemical tests showed marked elevation in aminotransaminases and hypergammaglobulinemia. Paradoxically, serum and salivary IgA levels were often normal or low. Histologic findings were multifocal hepatic necrosis with bridging in the acute stage, and aggressive hepatitis with mononuclear cell infiltration or macronodular cirrhosis in the late stages. Serologically, apart from the presence of antiliver/kidney microsome antibody type 1, the disease was characterized by the absence of antiactin, antimitochondria and antinucleus antibodies; however, organ-specific autoantibodies were often present. The clinical course was usually severe: six patients in the acute stage presented with fulminant hepatitis, and all, except two, other patients progressed to cirrhosis. Prolonged treatment with corticosteroids and immunosuppressants was usually effective in rendering the cirrhosis inactive. The cumulative survival rate was 51% at 14 years. We propose to call this entity "anti-LKM1 chronic active hepatitis" or "autoimmune hepatitis type II" to differentiate it from classical "lupoid hepatitis" or autoimmune hepatitis type I.

Fulminant hepatic failure resulting from hepatitis E and coexistent Wilson's disease was diagnosed in a six year old girl six weeks after returning from a holiday in India. Wilson's disease was diagnosed on the basis of histological evidence of hepatocellular copper deposition, confirmed by biochemical estimation of liver copper concentration. Although severely damaged, the liver was non-cirrhotic. Hepatitis E virus (HEV) was diagnosed by nested polymerase chain reaction, the specificity of which was confirmed by direct sequencing of amplified DNA. Replication of HEV within the liver at the time of diagnosis was confirmed by selective amplification of the antigenomic strand of the virus obtained from total liver RNA. The patient had an orthotopic liver transplantation without recurrence of hepatitis and remains well at 19 months. Viral excretion, recorded by serial amplification of HEV RNA extracted from stool samples, persisted for 30 days after liver grafting. Severe vitiligo, present preoperatively, dramatically improved after liver grafting and institution of immunosuppressive treatment. This case suggests that viral infection may play a part in the acute decompensation seen in some cases of Wilson's disease.

I clinically studied 905 patients with alopecia areata (AA) who visited the Department of Dermatology, College of Medicine, Chung Ang University, from January of 1982 to February of 1994. The purpose of the study was to evaluate the clinical manifestations and compare the effects of treatment with intralesional injection of triamcinolone acetonide suspension and immunotherapy with dinitrochlorobenzene (DNCB) or diphenylcyclopropenone (DPCP). The results were as follows: 1) The incidence of AA among all out-patients (59,970) was 1.5% (905 cases), and the ratio of males to females was 1.3:1 (512:393). 2) The age distribution showed high incidences in the third (41.8%) and fourth decades (20.0%). 3) The family history was contributory in 104 cases (11.5%). 4) The relapse rate was 17.5% (158 cases). 5) Almost half of the patients had a solitary lesion (408 cases, 46.7%). 6) The most common site of predilection was the occipital region of the scalp in both male and female patients. 7) Associated diseases were seborrheic dermatitis, atopic dermatitis, hepatitis, hypertension, open heart surgery, thyroid disease, pulmonary disease, and vitiligo in order of frequency. 8) The effect of treatment on the patients who had bald patches less than 50 cm2 was not significantly statistically different between intralesional injection of triamcinolone acetonide and immunotherapy with DNCB or DPCP. 9) In cases with bald areas more than 50 cm2, including alopecia totalis and universalis, DNCB or DPCP immunotherapy showed better therapeutic effects than did intralesional injection of triamcinolone acetonide.

Droxicam in a nonsteroid antiinflammatory from the oxicam family which acts as a pro-drug, being transformed into pyroxicam after being hydrolized in the stomach and has induced several cases of cholestatic or mixed hepatitis. A clinical observation in which droxicam provoked initial cholestatic hepatitis which later developed into chronic autoimmune hepatitis is presented. It has been postulated that, after causing cholestatic hepatitis by hypersensitivity and within the context of a previous autoimmune entity such as vitiligo, this drug triggered a silent autoimmune liver disease which was demonstrated clinical, analytical and histopathological manifestations 18 months later and required permanent immunosuppressive treatment.

Patients with autoimmune polyendocrine syndrome type I (APS I) have autoantibodies against the enzyme aromatic L-amino acid decarboxylase (AADC) of pancreatic beta-cells. The aim of the present study was to investigate the presence of anti-AADC antibodies in a large cohort of patients with APS I, and in patients with isolated insulin-dependent diabetes mellitus (IDDM). We found autoantibodies against AADC in 35 of 69 patients (51%) with APS I but in none of 138 patients with isolated IDDM or 91 healthy controls. Among the patients with APS I, anti-AADC antibodies were more often found in those with hepatitis (11/12, 92%), than in those without hepatitis (24/57, 42%) (P = 0.003). Similarly, of 15 patients with vitiligo, 12 (80%) had anti-AADC antibodies, compared with 23/54 (43%) without vitiligo (P = 0.021). Of the 9 APS I patients with IDDM, 5 had antibodies against both AADC and glutamate decarboxylase, 2 against AADC only, and 2 against glutamate decarboxylase only. Interestingly, AADC is present in relatively large amounts in the liver, where its function is unknown. Thus, an autoimmune reactivity against AADC may be involved in the pathogenesis of autoimmune chronic active hepatitis and vitiligo in APS I patients, whereas the role of AADC in the development of IDDM in these patients remains to be determined.

Autoimmune polyglandular syndrome type 1 (APS1) is characterized by a variable combination of disease components: (1) mucocutaneous candidiasis; (2) autoimmune tissue destruction; (3) ectodermal dystrophy. The disease is caused by mutations in a single gene called APECED (autoimmune polyendocrinopathy-candidiasis-ectodermal-dystrophy) or AIRE (autoimmune regulator) coding for a putative transcription factor featuring two zinc-finger (PHD-finger) motifs. APS1 shows a penetrance of 100%, lack of female preponderance and lack of association with HLA-DR. Typically, onset of APS1 occurs in childhood and multiple autoimmune manifestations evolve throughout lifetime. Organ-specific autoantibodies associated with hypoparathyroidism, adrenal and gonadal failures, IDDM, hepatitis and vitiligo are discussed, and autoantibody patterns in APS1 patients are compared with autoantibodies in APS type 2 (APS2). APS2 is characterized by adult onset adrenal failure associated with IDDM and/or hyperthyroidism. APS2 is believed to be polygenic, characterized by dominant inheritance and association with HLA DR3.

Autoantibodies against aromatic L-amino acid decarboxylase (AADC) are present in about 50 percent of sera from patients with autoimmune polyendocrine syndrome type I (APS I) but absent in sera from patients with different organ-specific autoimmune diseases, such as insulin-dependent diabetes mellitus, Hashimoto's thyroiditis, and Graves' disease. AADC is expressed in the pancreatic beta-cells, the liver, and the nervous system; and the presence of AADC antibodies has been shown to correlate to hepatitis and vitiligo in APS I patients. Among 101 investigated patients with autoimmune Addison's disease, 15 had high titers of AADC antibodies. According to the clinical characteristics of these patients, only 3 had APS I. The remaining 12 had either isolated Addison's disease or associated diabetes mellitus, hypothyroidism, vitiligo, alopecia, gonadal failure, and pernicious anemia. Autoantibodies against 21-hydroxylase were present in 9 of 12, whereas autoantibodies against side-chain cleavage enzyme and 17alpha-hydroxylase were present in 3 of 12. Two patients had only autoantibodies against AADC. DNA was available from 3 of these 12 patients. One of the patients, a woman with Addison's disease, autoimmune thyroiditis, and premature menopause was heterozygous for a point mutation (G1021A, Val301Met) in the first plant homeodomain zinc finger domain of the autoimmune regulator (AIRE) gene. The presence of AADC autoantibodies identifies patients with APS I and a subgroup of Addison patients who may have a milder atypical form of APS I or represent a distinct entity. Measurement of autoantibodies against AADC should be included in the evaluation of Addison's disease.
