Although monogenic diseases often show extreme clinical phenotypes, the major burden of genetic ill health lies in the more prevalent polygenic disorders, such as diabetes, hypertension and multiple sclerosis. These conditions affect many thousands of individuals and their management consumes vast amounts of health care resources: in the UK some 80,000 people have multiple sclerosis; the estimated financial cost to society of introducing treatments, such as beta interferon, could be as high as 250 million pounds per year. Knowledge on the genetics of these common diseases is poor, but has potentially received a considerable boost with the arrival of whole genome screening. The genome screen in insulin-dependent diabetes mellitus (IDDM) reported in 1994 was the first in a human polygenic disease. Since this publication, whole genome screening has been performed in a variety of human polygenic diseases, including schizophrenia, bipolar affective disorder, non-insulin-dependent diabetes mellitus (NIDDM), inflammatory bowel disease, asthma and multiple sclerosis.

Pyoderma gangrenosum is a chronic inflammatory ulcerative skin disease of unknown etiology, often associated with various systemic disorders such as inflammatory bowel disease, rheumatoid arthritis, chronic active hepatitis, diabetes mellitus and hematologic malignancies. The ulcers are characterized by their undermined violaceous borders. The disease remains a therapeutic challenge. Corticosteroids are the mainstay of therapy; however, side effects from this treatment and recalcitrant pyoderma gangrenosum require therapeutic alternatives. We report the case of a large subacute pyoderma gangrenosum stabilized with lymecycline, topical benzoyl peroxide and successfully treated by an autograft. This observation supports the opinion that the risk of pathergy of a graft can be avoided by the stabilization of the disease.

1. Autoimmune diseases are common conditions which appear to develop in genetically susceptible individuals, with expression of disease being modified by permissive and protective environments. Familial clustering and data from twin studies provided the impetus for the search for putative loci. Both the candidate gene approach in population-based case-control studies and entire genome screening in families have helped identify susceptibility genes in a number of autoimmune diseases. 2. After the first genome screen in type 1 (insulin-dependent) diabetes mellitus it seems likely that most autoimmune diseases are polygenic with no single gene being either necessary or sufficient for disease development. Of the organ-specific autoimmune diseases, genome screens have now been completed in insulin-dependent diabetes mellitus and multiple sclerosis. Furthermore, the clustering of autoimmune diseases within the same individuals suggests that the same genes may be involved in the different diseases. This is supported by data showing that both HLA (human leucocyte antigen) and CTLA-4 (cytotoxic T-lymphocyte-associated-4) appear to be involved in the development of insulin-dependent diabetes mellitus and Graves' disease. 3. Genome screens have also been completed in some of the non-organ-specific autoimmune diseases including rheumatoid arthritis, inflammatory bowel disease and psoriasis. Many candidate genes have also been investigated although these are predominantly in population-based case-control studies. 4. Substantial progress has been made in recent years towards the identification of susceptibility loci in autoimmune diseases. The inconsistencies seen between case-control studies may largely be due to genetic mismatching between cases and controls in small datasets. Family-based association studies are being increasingly used to confirm genetic linkages and help with fine mapping strategies. It will, however, require a combination of biology and genetics, as has been necessary with the major histocompatibility complex in insulin-dependent diabetes mellitus, to identify primary aetiological mutations.

Autoantigen-specific CD4+ T cells have been implicated as the causative cell type in: multiple sclerosis, rheumatoid arthritis, autoimmune uveitis, diabetes mellitus, inflammatory bowel disease and graft-versus-host disease. The pathology of a number of experimentally induced autoimmune diseases is also mediated by autoantigen-specific CD4+ T cells. Ideally, treatment of CD4+ T-cell-mediated diseases would eliminate the autoantigen-specific cells, while sparing the remainder of the T-cell repertoire. We have developed an effective therapy that deletes the autoreactive T cells at the site of autoimmune tissue destruction. This approach uses an antibody directed against a cell-surface protein (OX-40, also known as CD134) that is selectively upregulated on activated autoantigen-specific T cells within the inflamed tissue.

The Central Medical Pharmaceutical Committee of the Health Insurance Council informs the medical profession annually about the effects of drugs through the Pharmacotherapeutical Compass. The 1998 edition now contains a chapter on pharmacokinetics as well. Compared with previous editions the main alterations of the contents concern an introduction and advice on the antidepressants, two protocols with respect to the medical treatment of patients suffering from epilepsy, advice with respect to oral drugs for the treatment of inflammatory bowel disease, an introduction and advice regarding the treatment of allergic rhinitis, the treatment of patients suffering from AIDS with antiretroviral drugs, the treatment of genital herpes, the taking of insulin lispro by patients with diabetes and the taking of bisphosphonates to prevent or to treat osteoporosis. Two corrections to the 1998 edition are given.

Breast-feeding protects the newborn against infectious diseases in developing as well as in industrialized countries. Protection is conferred against gastrointestinal and respiratory tract diseases as well as against otitis media. This protection provided by specific (antibody dependent) and broad, nonspecific protective factors in human milk (proteins, glycoproteins, and lipids) is associated with lower global morbidity and mortality of breast-fed infants as compared with formula-fed infants. While protection against diseases that develop later in life, such as insulin-dependent diabetes mellitus, inflammatory bowel disease, and childhood cancer, has been reported, well-planned prospective studies are essential in order to confirm these observations. Similar studies are essential in order to ascertain the small but consistently reported higher cognitive ability of breast-fed infants.

Both achalasia and Hirchsprung's disease arise from defects of innervation of the oesophagus and distal large bowel respectively. Their consequences are confined to disorders of motility in the relevant part of the gastrointestinal tract. Many neurogenic and primary muscle disorders are associated with abnormalities of gut motility. Stroke, even when unilateral, is commonly associated with dysphagia. Transcranial magnetoelectric stimulation has established that the pharyngeal phase of swallowing tends to receive its innervation principally from one hemisphere. In many neurological disorders, dysphagia is only one part of the clinical picture but in some--for example, the Chiari malformation--dysphagia may be the sole or major feature. Disturbances of small and large bowel motility, when seen in neurogenic disorders, are associated with autonomic neuropathy and are particularly common in diabetes mellitus. Primary muscle disorders can lead to dysphagia (for example, with polymyositis or oculopharyngeal dystrophy) or defects of large bowel motility (for example, with Duchenne's muscular dystrophy). Primary gut disorders particularly associated with neurological disease include pernicious anaemia, nicotinamide and thiamine deficiencies, selective vitamin E deficiency, and coeliac disease. Inflammatory bowel disease is associated with thromboembolic complications which may include the CNS, inflammatory muscle disease, and abnormalities on MRI of the brain of uncertain relevance. Whipple's disease is a rare condition which sometimes is largely or entirely confined to the CNS. In such cases, a particular neurological presentation can indicate the diagnosis.

Adjuvant-induced arthritis (AIA) in rats is a widely used autoimmune experimental model with many features similar to rheumatoid arthritis (RA). To identify potential genetic regulatory mechanisms in RA, we conducted genome-wide linkage analysis in F2 progeny of arthritis-susceptible Dark Agouti (DA) and relatively resistant Fischer 344 (F344) inbred rats. We compared the data with our previously reported investigation of collagen-induced arthritis (CIA), which was expanded in the follow-up study reported in this work. We found two quantitative trait loci (QTLs) in common, i.e., Aia1/Cia1 on chromosome 20, which includes the MHC, and Aia3/Cia3 on chromosome 4. We also identified a second unique QTL in AIA, Aia2, on chromosome 4. Interestingly, the QTL region on chromosome 4 (Aia3/Cia3), like the MHC, appears to be involved in several other autoimmune diseases in rats, including insulin-dependent diabetes, thyroiditis, and experimental autoimmune uveitis. Moreover, an analysis of conserved synteny among rats, mice, and humans suggested that Aia2 and Aia3/Cia3, like Aia1/Cia1, contain candidate genes for several autoimmune/inflammatory diseases in mice and humans, including diabetes, systemic lupus erythematosus, inflammatory bowel disease, asthma/atopy, multiple sclerosis, and RA. The rat models appear to provide a powerful complementary approach to identify and characterize candidate genes that may contribute to autoimmune diseases in several species.

Helicobacter pylori (H. pylori) is the most common cause of peptic ulcers, and is considered as carcinogenic with respect to gastric cancer and MALT lymphoma. The role of H. pylori in other gastroduodenal diseases like atrophic gastritis and functional dyspepsia has been investigated in hundreds of works, but little is done about what role H. pylori may play in non gastric diseases. Gastro-esophageal reflux disease does not seem to be related to H. pylori but Barrett's esophagus might be. Inflammatory bowel diseases tend to be reverse correlated with H. pylori. In coronary heart disease some studies have shown a connection, others not. Diabetes is not likely to be H. pylori-associated and nor do liver diseases with exception for cirrhosis, where a correlation is possible. Respiratory diseases are little examined but bronchiectasis might have a correlation with H. pylori. A small series of children, who had died in sudden infant death, showed a high rate of H. pylori infection.

The incidence of immune-mediated diseases is increasing worldwide. Reliable immune markers for monitoring disease progression and also the effect of therapeutic interventions are urgently needed in order to investigate preventive or therapeutic measures effectively. At a recent workshop held on 5 December 1998 in Copenhagen, the state of research on surrogate markers in Type 1 diabetes was discussed and compared with the experience in multiple sclerosis, inflammatory bowel disease and transplantation.
