Genetic analysis as a valuable key to diagnosis and treatment of periodic Fever.
We describe 2 Dutch patients with recurrent fever attacks undiagnosed for more than 40 years. The diagnosis of periodic fever was made when molecular analysis revealed novel mutations in the tumor necrosis factor (TNF) receptor gene (TNFRSF1A), establishing the diagnosis of TNF receptor-associated periodic syndrome. This syndrome is an autosomal dominant disorder characterized by recurring episodes of fever, arthralgia, and skin lesions that is caused by mutations in the 55-kd TNFRSF1A gene. This finding has facilitated treatment for TNF receptor-associated periodic syndrome because blocking of TNF signaling seems to alleviate the symptoms. Use of a short course of recombinant p75TNFR:Fc fusion protein (etanercept) induced prolonged remission in one patient.

Evaluation of (pre-)malignant colonic abnormalities: endoscopic validation of FDG-PET findings.
The diagnostic accuracy of 2-[(18)F]-fluoro-2-deoxy- D-glucose positron emission tomography (FDG-PET) for the detection of (pre-)malignant lesions of the colon was compared with that of endoscopy. We selected a cohort of 39 patients [13 females and 26 males; mean age 62.3 years standard deviation (SD) 9.6 years] who underwent both FDG-PET and endoscopy (total of 44 procedures) in a 2-year period with a maximum interval between the examinations of 3 months (mean 30 days, SD 28 days). The underlying pathology was colorectal malignancies (24 patients), other malignancies (nine patients) and other disorders (six patients). Follow-up of resected colorectal cancer was the most common reason for the performance of endoscopy. In 19 patients FDG bowel uptake was interpreted as non-physiological, and in 18 patients abnormal findings (adenomatous polyps >3 mm or carcinoma) were detected by endoscopy. Compared with colonoscopy, FDG-PET had a sensitivity of 74% and specificity of 84%. The positive predictive value of FDG-PET was 78%. FDG-PET failed to detect small (diameter 3-10 mm) polyps in four patients. In nine cases abnormal FDG accumulation on PET imaging was the sole reason for performance of an endoscopic procedure. In these cases, endoscopy detected large adenomatous polyps in four patients and carcinomas in two patients, but no abnormalities were detected on endoscopy in the other three patients. There was a good correlation between the location of FDG uptake and endoscopy-positive lesions. FDG-PET is able to detect clinically relevant lesions of the colon. Our study suggests that it can be regarded as a useful adjunct in the non-invasive follow-up of patients with colorectal carcinomas.

Molecular analysis of the mevalonate kinase gene in a cohort of patients with the hyper-igd and periodic fever syndrome: its application as a diagnostic tool.
BACKGROUND: The hyper-IgD and periodic fever syndrome (HIDS) is characterized by recurrent attacks of fever, abdominal distress, and arthralgia and is caused by mevalonate kinase mutations. OBJECTIVE: To ascertain the role of mevalonate kinase and the usefulness of molecular diagnosis in HIDS. DESIGN: Cross-sectional study. SETTING: The international Nijmegen HIDS registry. PATIENTS: 54 patients from 41 families who met the clinical criteria for HIDS. MEASUREMENTS: Clinical symptoms and signs, immunoglobulin concentration, leukocyte count, erythrocyte sedimentation rate, mutation analysis, and mevalonate kinase enzyme activity assay. RESULTS: There were two groups of patients: 41 patients with mevalonate kinase mutations (classic-type HIDS) and 13 patients without mutations (variant-type HIDS). Patients with classic-type HIDS had a lower mevalonate kinase enzyme activity, a higher IgD level, and more additional symptoms with attacks. The IgD level did not correlate with disease severity, mevalonate kinase enzyme activity, or genotype. CONCLUSION: Genetic heterogeneity exists among patients with a clinical diagnosis of HIDS.

The primary erythermalgia-susceptibility gene is located on chromosome 2q31-32.
Primary erythermalgia is a rare disorder characterized by recurrent attacks of red, warm, and painful hands and/or feet. The symptoms are generally refractory to treatment and persist throughout life. Five kindreds with multiple cases of primary erythermalgia were identified, and the largest was subjected to a genomewide search. We detected strong evidence for linkage of the primary erythermalgia locus to markers from chromosome 2q. The highest LOD score (Z) was obtained with D2S2330 (Z(max) = 6.51). Analysis of recombination events identified D2S2370 and D2S1776 as flanking markers, on chromosome 2q31-32. This defines a critical interval of 7.94 cM that harbors the primary erythermalgia gene. Affected members within the additional families also shared a common haplotype on chromosome 2q31-32, supporting our linkage results. Identification of the primary erythermalgia gene will allow a better clinical classification of this pleomorphic group of disorders.

[From gene to disease; tumor necrosis factor receptor and a syndrome of familial periodic fever].
Familial Hibernian fever (FHF) is a rare hereditary syndrome that causes periodic attacks of fever and inflammation. It is an autosomal dominantly inherited disorder. The gene involved in FHF encodes for a receptor for tumour necrosis factor (TNFR1). These mutations are thought to result in impaired shedding of the receptor from the cell membrane, leading to deficient curtailing of the inflammatory reaction. The acronym TRAPS (TNF-receptor associated periodic syndrome) has been proposed as a more accurate name.

Molecular analysis of MVK mutations and enzymatic activity in hyper-IgD and periodic fever syndrome.
Hyperimmunoglobulinaemia D and periodic fever syndrome (HIDS) is an autosomal recessive inflammatory disorder characterised by recurrent episode of fever associated with lymphadenopathy, abdominal distress, joint involvement and skin lesions. We recently demonstrated that mutations in the mevalonate kinase gene (MVK) are associated with HIDS. Direct DNA sequencing was done to screen the entire coding region of MVK in 25 unrelated patients with HIDS. Mutations were detected in the coding region of the gene including 11 missense mutations, one deletion, the absence of expression of one allele, as well as three novel polymorphisms. Seven of these mutations are novel. The large majority of the patients were compound heterozygotes for two mutations. Of these, V377I (G-->A) is the most common mutation occurring in 20 unrelated patients and was found to be associated with I268T in six patients. Mutations were associated with a decrease of mevalonate kinase (MK) (ATP:mevalonate 5-phosphotransferase, EC 2.7.I.36) enzymatic activity but not as profound as in mevalonic aciduria, a syndrome also caused by a deficient activity of MK. In HIDS the mutations are located all along the protein which is different from mevalonic aciduria where MK mutations are mainly clustered to a same region of the protein. On the basis of this study, we propose that the diagnostic screen of MVK in HIDS should be first directed on V377I and I268T mutations. Three patients are also described to illustrate the genotypic and phenotypic overlap with mevalonic aciduria.

Hyper-immunoglobulin A in the hyperimmunoglobulinemia D syndrome.
The hyperimmunoglobulinemia D syndrome (HIDS) is an autosomal recessive disorder characterized by recurrent febrile attacks with abdominal, articular, and skin manifestations. Apart from elevated immunoglobulin D (IgD) levels (>100 IU/ml), there are high IgA levels in the majority of cases. Mutations in the gene encoding mevalonate kinase constitute the molecular defect in HIDS. The cause of elevated IgA concentrations in HIDS patients remains to be elucidated. We studied the hyper-IgA response in serum of a group of HIDS patients. Elevated IgA concentrations result from increased IgA1 concentrations. IgA and IgA1 concentrations correlated significantly with IgD concentrations, and levels of IgA polymers were significantly higher than the levels in healthy donors. These results indicate a continuous, presumably systemic, stimulation of IgA in HIDS patients.

Specific glycosylation of alpha(1)-acid glycoprotein characterises patients with familial Mediterranean fever and obligatory carriers of MEFV.
BACKGROUND: Familial Mediterranean fever (FMF) is a periodic febrile disorder, characterised by fever and serositis. The acute phase response during attacks of FMF results from the release of cytokines, which in turn induce increased expression and changed glycosylation of acute phase proteins. A recent study indicated that attacks in FMF are accompanied by a rise of plasma concentrations of serum amyloid A (SAA) and C reactive protein (CRP), which remain significantly raised during remission relative to healthy controls. Another study suggested that obligatory heterozygotes also display an inflammatory acute phase response. OBJECTIVE: To determine the state of inflammation in homozygotic and heterozygotic MEFV genotypes. METHODS: CRP and SAA were studied by enzyme linked immunosorbent assay (ELISA). The glycosylation of the acute phase protein, alpha(1)-acid glycoprotein (AGP), was visualised with crossed affinoimmunoelectrophoresis with concanavalin A as diantennary glycan-specific component and Aleuria aurantia lectin as fucose-specific affinity component. RESULTS: FMF attacks were associated with an increase (p<0.05) in the serum inflammation parameters CRP, SAA, and AGP. The glycosylation of AGP showed an increase (p<0.05) in fucosylated AGP glycoforms, whereas the branching of the glycans remained unaffected. The glycosylation of AGP in the MEFV carrier group, compared with that in a healthy control group, was characterised by a significant increase (p<0.05) in branching of the glycans, whereas the fucosylation remained unaffected. CONCLUSION: The findings suggest an FMF-specific release of cytokines, resulting in a different glycosylation of AGP between a homozygotic and heterozygotic MEFV genotype.

Limited efficacy of thalidomide in the treatment of febrile attacks of the hyper-IgD and periodic fever syndrome: a randomized, double-blind, placebo-controlled trial.
Hyper-IgD and periodic fever syndrome (HIDS) is an autosomal recessive disorder featured by recurrent febrile attacks. Previous unpublished experience (J. van der Meer and R. Powell) suggested that thalidomide may prevent febrile attacks. Six HIDS patients (5 male and 1 female) who had at least one febrile attack every 6 weeks, entered a randomized, double-blind, placebo-controlled crossover trial to explore the efficacy of a daily 200-mg thalidomide dose in the treatment of recurrent febrile attacks of HIDS. The patients received either thalidomide, 200-mg daily, or placebo for 16 weeks, followed by a 4-week washout period and another 16-week treatment (crossover) with either thalidomide or placebo. Patients completed a weekly diary card noting attacks and side effects. During the study, C-reactive protein (CRP), serum amyloid A (SAA), interleukin (IL)-6, tumor necrosis factor (TNF)-alpha, IL-1 receptor antagonist, soluble TNF receptor p55 and p75, and lipopolysaccharide-stimulated IL-1 beta and TNF-alpha production were measured at six different points, whereas urine neopterin levels were measured weekly. During the active treatment with thalidomide, there were 10 attacks compared with 13 attacks with placebo. Thalidomide resulted in a nonsignificant decrease of CRP and SAA, but the concentrations of other inflammatory mediators, including urine neopterin, remained unchanged. One patient developed sensory polyneuropathy, but this resolved when thalidomide administration was stopped. The effect of thalidomide in HIDS is limited to a decrease in acute phase protein synthesis without an effect on the attack rate.

Iron saturation of serum ferritin in patients with adult onset Still's disease.
OBJECTIVE: Patients with Still's disease show a prominent acute phase reaction. Our hypothesis is that under these circumstances the iron uptake of ferritin will not keep pace with its synthesis, and is therefore not a valid reflection of the iron status in these patients. METHODS: Previously we developed a method to measure the iron content of ferritin; we investigated the usefulness of this method to establish the iron status of patients with anemia of inflammation. RESULTS: In 9 patients with adult onset Still's disease (AOSD) we observed high ferritin concentrations and measured the iron saturation of ferritin. The mean value of saturation was 9.1%, while saturation in the healthy control group was 17.8%, a statistically significant difference (p < 0.005). Soluble transferrin receptor concentrations indicated a functional iron deficiency. CONCLUSION: We conclude that the acute phase ferritin in patients with AOSD contains less iron in comparison to ferritin in healthy controls. We suggest that soluble transferrin receptor is the method of choice in estimating the iron status of patients with an acute phase reaction.

[From gene to disease; hereditary pancreatitis].
Hereditary pancreatitis is an autosomal dominant form of chronic pancreatitis. It presents with recurrent attacks of acute pancreatitis, usually starting in early childhood. The attacks may vary from mild abdominal pain to pancreatic necrosis, splenic vein thrombosis, pseudocysts and death. Ultimately chronic pancreatitis ensues with unrelenting pain, calcifications, endocrine and exocrine dysfunction. The penetrance is estimated at 80%. With the use of genetic linkage analysis the gene for hereditary pancreatitis was placed on the long arm of chromosome 7 (7q35). Mutational analysis identified cationic trypsinogen as the disease gene. Cationic trypsinogen mutations are thought to result in resistance of this molecule to autolysis.

[Aortic stenosis and intestinal blood loss from angiodysplasia: valve replacement is a therapeutic option].
Three patients, men aged 67, 68 en 61, had for many years suffered from recurrent iron deficient anaemia and were found to have an aortic stenosis. Coloscopy identified angiodysplastic lesions, and we suspected additional lesions in the small intestine. Despite surgical and endoscopic treatment, gastrointestinal bleeding recurred. Replacement of the stenosed aortic valve with a bioprosthesis led to a recovery in the haemoglobin levels of all three patients. Angiodysplasias are a common source of gastrointestinal bleeding with an invisible origin. Data from the literature suggest an association between aortic stenosis and angiodysplasia although epidemiological evidence is lacking.

[Identification of the gene for hyper-IgD syndrome: a model of modern genetics].
Hyperimmunoglobulinaemia D and periodic fever syndrome (HIDS) is a rare autosomal recessive disorder. Patients suffer from recurrent attacks (3-6 days) with fever, abdominal distress, lymphadenopathy, skin lesions and arthralgias. Patients display a constantly elevated serum IgD which serves as a biological marker of the disease. Recently, the gene for HIDS was discovered by two independent groups using positional and functional cloning methods. One group used linkage analysis (positional cloning) and was able to locate the gene for HIDS on the long arm of chromosome 12 (12q24). Mevalonate kinase was an interesting candidate gene because patients with a near complete absence of this enzyme (mevalonic aciduria) do exhibit attacks of fever. Indeed subsequent data showed that there was a decreased enzyme activity due to missense mutations in the mevalonate kinase gene. The other group detected slightly elevated urinary excretion of mevalonic acid during attacks in a HIDS patient (functional cloning). The enzyme activity of mevalonate kinase was lower in cultured cells and sequence analysis identified several missense mutations in cDNA encoding for mevalonate kinase. Mevalonate kinase is a key enzyme in the cholesterol synthesis pathway and it is rather surprising that a defect in the cholesterol metabolism can cause a periodic inflammatory disease such as HIDS.
