A method and approach are described to differentiate classic autoimmune thrombocytopenia (ATP) from immune complex-associated thrombocytopenia in systemic lupus (SLE), hepatitis/chronic liver disease (LIV-ITP) and HIV-1 related thrombocytopenia (HIV-1-ITP). The platelet immunologic profile of IgG, C3C4 and IgM was measured with a solid-phase ELISA, employing 125I-staphylococcal protein A to detect indicator antibody binding. Polyethylene glycol was employed to precipitate immune complexes (PEG-IC). Platelet-associated IgG (PAIgG) was 2.8-, 5.6- and 5.8-fold higher in SLE, LIV-ITP and HIV-1-ITP patients respectively compared to ATP patients: platelet C3C4 was 3.2-, 4.8- and 4.5-fold higher respectively; platelet IgM was 2.2-, 3.7- and 3.8-fold higher respectively; serum PEG-IC levels were 4.2-, 4.8- and 2.1-fold higher respectively. With all parameters measured, there was no overlap between the 75th percentile for ATP patients and the 25th percentile for all three cohorts. The likelihood of having a platelet C3C4 level higher than the highest ATP level was 69% for SLE, 90% for LIV-ITP and 94% for HIV-1-ITP respectively; with PEG-IC measurements the likelihood was 83%, 100% and 100% respectively. Serum IgG, C3, C4, IgM and PEG-IC were examined for a possible relationship with platelet measurements. Except for a positive correlation between serum and platelet IgM in ATP, r = 0.5, P < 0.04, there was no positive correlation with any of the parameters measured. An inverse correlation was noted between PEG-IC level and platelet C3C4 in SLE, r = 0.7, P < 0.04. Thus platelet immunologic profile and serum PEG-IC level measurements differentiated classic ATP from immune complex-associated thrombocytopenias (SLE, LIV-ITP, HIV-1-ITP). Except for IgM measurements in ATP, platelet measurements could not be attributed to their respective serum concentration.

Minocycline is the most widely prescribed systemic antibiotic for the management of acne. In the past several years, increasing attention has been paid to the drug, both for its potential use as a disease-modifying antirheumatic agent and for its propensity to engender untoward autoimmune reactions, including serum sickness-like disease, drug-induced lupus, and autoimmune hepatitis. This paper reviews the evidence for minocycline as an anti-inflammatory and immunomodulatory agent, its utility in the treatment of rheumatoid arthritis, and the spectrum of adverse reactions that have been ascribed to the drug in the past 5 years.

We report four cases of the side effects of minocycline seen during the last two years in our department. There was one case of drug-related lupus and three cases of hypersensitivity reactions, including one eosinophilic pneumopathy with pericarditis, one nephropathy and one severe, pseudo-infectious episode of high fever, rash, lympadenopathy, hepatitis and eosinophilia. Minocycline is a tetracycline agent widely used for acne therapy in France and all over the world. During the last few years, there has been an increasing number of reports concerning systemic adverse reactions to minocycline, with on the one hand auto-immune disorders (lupus, autoimmune hepatitis, vascularitis with ANCA), occurring after a prolonged course of therapy and reported recently in the last few years, and on the other hand, hypersensitivity reactions (eosinophilic pneumopathies, hepatitis, nephropathies, myocarditis, serum sickness or pseudo-infectious reactions), occurring precociously in the course of therapy, and potentially severe. Although these side effects are uncommon in the context of the high number of patients who have been prescribed the drug, the first-line antibiotic therapy in acne must probably be reconsidered.

A case of idiopathic portal hypertension (IPH) associated with systemic lupus erythematosus (SLE) is reported in a 38-year-old man who had been diagnosed with SLE and treated for 18 years. Esophageal varices. found in 1994 on endoscopic examination, had been followed up for 2 years. On July 16, 1996, he was admitted to Nagoya University Hospital because there was a high risk of bleeding from the esophageal varices due to severe thrombocytopenia. As partial splenic embolization had temporarily controlled the thrombocytopenia, splenectomy and devascularization of the stomach vessels were performed after endoscopic ligation of the esophageal varices. Histological specimens of wedge biopsied liver showed chronic inactive hepatitis without cirrhosis. The presence of anticardiolipin antibody, indicated by positivity for lupus anticoagulant, was suggestive of the presence of a common immunological mechanism in the etiology of SLE and IPH.

A 24-year-old woman was followed for about ten months with oral administration of prednisolone (22.5-35 mg/d) for autoimmune hepatitis. In June 1995, she noticed fatigue and appetite loss and blood chemistry revealed markedly deteriorated liver function. She was admitted to our hospital. The daily dose of prednisolone was increased to 60 mg. Her elevated levels of transaminases decreased gradually. Administration of azathioprine (100 mg/d) was started with tapering of prednisolone on August 18th. Ten days later, tender cervical lymphadenopathy and high fever occurred. Azathioprine administration was stopped immediately and intravenous antibiotics were given. On September 5th, 50 mg of azathioprine was administered again. Two hours later, the patient complained of intolerable pain from the lumbar region to the knee joints, which subsided following two injections of analgesics within a few hours. However, chills, high fever and hypotension (86/30 mmHg) subsequently developed. No bacterial growth was detected in blood culture. She was discharged on September 12th. On October 4th, she visited our out-patient clinic. The next day, she took one tablet (50 mg) of azathioprine at 10 o'clock. She noted intense pain from the thighs to the knees and calves around noon again. Her home doctor found that she exhibited shock (BP 67/?). She was immediately taken to our department. The same symptoms and signs as the above-mentioned occurred. Azathioprine was considered responsible for these two adverse reactions (shock) as an allergen. Later, systemic lupus eythematosus was diagnosed in 1996. And she died to pulmonary hypertension in May 1999. Physicians should be aware of the potential adverse effect of azathioprine administered in order to manage the patients with autoimmune disorders.

We present two siblings with congenital and progressive encephalopathy associated with systemic lupus erythematosus. The two brothers presented soon after birth with an encephalopathy associated with intracranial calcification (=2), intrauterine growth retardation (= 2), hepatitis (= 1) and thrombocytopenia (= 1), mimicking a congenital virus infection. Within the first year of life both children developed hypocomplementaemia and systemic lupus erythematosus (SLE), the main features of which were a discoid lupus-like rash on the hands and feet and the progressive production of high levels of autoantibodies. Both children were severely handicapped and died in early childhood from streptococcal infections. There are many causes of congenital encephalopathy with intracranial calcification. The early development of systemic lupus in these children suggested that their cerebral disease formed part of an autoimmune process. Complement levels and autoantibody profiles should be considered part of the investigation of a child with congenital infection-like syndrome, particularly when there are progressive dermatological complications.

Minocycline is an oral antibiotic widely used for the long-term treatment of acne vulgaris. Unusual side effects of this medication include two overlapping autoimmune syndromes: drug-induced lupus and autoimmune hepatitis. In addition, in a few patients livedo reticularis or subcutaneous nodules have developed in association with arthritis and serum perinuclear antineutrophil cytoplasmic antibodies (P-ANCA) during long-term minocycline therapy. We report the cases of two young women receiving long-term minocycline therapy (>3 years) in whom P-ANCA-positive cutaneous polyarteritis nodosa developed. Both patients presented with a violaceous reticulated pattern on the lower extremities. Histologic examination of biopsy specimens from a reticulated area and a subcutaneous nodule showed necrotizing vasculitis of medium-sized arteries in the deep dermis, consistent with the diagnosis of polyarteritis nodosa. The cutaneous lesions rapidly resolved on discontinuation of minocycline and initiation of prednisone therapy. A high index of suspicion and testing for antineutrophil cytoplasmic antibody in addition to the standard antinuclear antibody panel can facilitate diagnosis of minocycline-related autoimmune disorders.

Lupus erythematosus panniculitis (profundus), a rare variant of chronic panniculitis, sometimes develops during the course of discoid lupus erythematosus or systemic lupus erythematosus. A 61-year-old woman had suffered from autoimmune hepatitis type I for 5 years. Prednisolone had been administered as maintenance therapy and her hepatitis had been well controlled. However, asymptomatic erythematous indurated nodules developed symmetrically in both pre-auricular regions, and skin biopsy revealed lupus erythematosus panniculitis (profundus). Increase in dosage of prednisolone resolved the skin lesion, leaving depressed atrophic scars. This is the first report of lupus erythematosus panniculitis complicating autoimmune hepatitis.

We have investigated the molecular basis of selective and complete C1s deficiency in 2-year-old girl with complex autoimmune diseases including lupus-like syndrome, Hashimoto's thyroiditis, and autoimmune hepatitis. This patient's complement profile was characterized by the absence of CH50 activity, C1 functional activity <10%, and undetectable levels of C1s Ag associated with normal levels of C1r and C1q Ags. Exon-specific amplification of genomic DNA by PCR followed by direct sequence analysis revealed a homozygous nonsense mutation in the C1s gene exon XII at codon 534, caused by a nucleotide substitution from C (CGA for arginine) to T (TGA for stop codon). Both parents were heterozygous for this mutation. We used the new restriction site for endonuclease Fok-1 created by the mutation to detect this mutation in the genomic DNA of seven healthy family members. Four additional heterozygotes for the mutation were identified in two generations. Our data characterize for the first time the genetic defect of a selective and complete C1s deficiency in a Caucasian patient.

The antiphospholipid syndrome has rarely been described in patients with autoimmune hepatitis. Two cases with type I autoimmune hepatitis and antiphospholipid syndrome are presented. The first case is that of a 53-year-old Caucasian female with a history of arterial thrombosis and fetal loss who was submitted to clinical and laboratory testing due to persistent transaminasaemia and was found to have autoimmune hepatitis. Antiphospholipid antibodies (anticardiolipin antibodies and lupus anticoagulant) were positive. The second case is that of a 31-year-old Caucasian woman with a history of autoimmune hepatitis who was submitted to laboratory testing due to a second-trimester fetal death, revealing an increased activated partial thromboplastin time and positive antiphospholipid antibodies. In conclusion, secondary antiphospholipid syndrome may accompany autoimmune hepatitis.
