We describe a patient suffering from an abdominal inflammatory mass due to chronic yersiniosis. Functional assays revealed defects in the recognition of flagellin by Toll-like receptor 5 (TLR5) and of muramyl dipeptide by NOD2, leading to a defective inflammatory response to Yersinia enterocolitica.

Treatment with IL-1 receptor antagonist anakinra resulted in complete resolution of these symptoms, with a radical beneficial change in her quality of life. In recent years this patient had developed progressive neurological symptoms leading to a diagnosis of amyotrophic lateral sclerosis (ALS), which seems unrelated to the idiopathic cold urticaria. The neurological symptoms did not respond to anakinra treatment and were eventually fatal. Conclusion: We describe the first case of IL-1RA treatment in idiopathic cold urticaria with good response.

Although several abnormalities of T-cell populations have been described in HCL, the effector mechanism responsible for the increased susceptibility to infections is not known. METHODS: Blood was collected from 11 patients with HCL and 22 age- and gender-matched volunteers. Proinflammatory cytokine production by freshly isolated mononuclear cells was stimulated with either lipopolysaccharide or various heat-killed microorganisms. Cytokine concentrations were assessed by specific ELISAs. RESULTS: We demonstrate that mononuclear cells harvested from HCL patients have a specific defect of IFNgamma production when stimulated with a broad panel of bacterial stimuli. In contrast, the production of other proinflammatory cytokines, such as TNF, IL-1beta and IL-6, did not differ between HCL patients and controls.

One patient had documented systemic lupus erythematosus (SLE), the other three patients had primary hypogammaglobulinaemia without known cause. Whereas the cessation of azathioprine therapy may have contributed to the recovery in the patient with SLE, the restoration of the immunoglobulin production in the other three patients occurred spontaneously. All four patients were IgA deficient when the hypogammaglobulinaemia was first detected and remained so after IgM and IgG production had recovered. Two of the three patients who also had anti-IgA antibodies started to produce anti-IgA again after stopping the immunoglobulin substitution. We conclude that recovery of hypogammaglobulinaemia is possible but rare. When recovery is suspected, we recommend that immunoglobulin substitution is stopped and the antibody response to vaccination is tested. TI - Reversible hypogammaglobulinaemia.

One patient, with documented pernicious anaemia and chronic atrophic gastritis with metaplasia, developed a Helicobacter pylori-positive extranodal marginal zone lymphoma in the stomach. Three triple regimens of antibiotics were necessary to eliminate the H. pylori, after which the lymphoma completely regressed. Patient B had an H. pylori-negative extranodal marginal zone lymphoma of the parotid gland, which remarkably regressed after treatment with clarithromycin. Reviewing the literature, we found eight cases of extranodal marginal zone lymphoma complicating CVID, but probably many more cases labelled as non-Hodgkin's lymphoma are hidden in the literature. Until more data are available on the predictive value of noninvasive screening for pathology of the stomach, we recommend endoscopy to assess the gastric status in CVID patients in order to detect these malignancies at an early stage. Elimination of H. pylori infection is the treatment of choice in Helicobacter-positive extranodal marginal zone lymphoma. The possibility of elimination failure, most probably due to frequent and prolonged exposure to antibiotics in this patient group, should be taken into account. Treatment with antibiotics in Helicobacter-negative extranodal marginal zone lymphoma must be considered. TI - Extranodal marginal zone (MALT) lymphoma in common variable immunodeficiency.

NOD2 is a cytoplasmic receptor for the bacterial product peptidoglycan. There is considerable controversy in the literature whether the most common mutation in Crohn's disease, the 3020insC NOD2, leads to a loss of function, i.e. decreased cytokine production, or to the reverse, i.e. a gain of function. In previous papers we proposed the former, since we could show decreased cytokine production with a net proinflammatory status after exposure to muramyl dipeptide (MDP). METHODS: Because of recent data in the literature showing increased interleukin-beta (IL-1beta) production in mice with the corresponding NOD2 mutation, we investigated the production of this cytokine by cells of patients with Crohn's disease, either homozygous or heterozygous for the 3020insC mutation, and compared it with that of patients with Crohn's disease bearing the wild-type allele. RESULTS: A strongly decreased production of IL-1beta by peripheral mononuclear cells was found upon exposure to either peptidoglycan or peptidoglycan-derived MDP in homozygous patients bearing the 3020insC NOD2mutation. CONCLUSION: This sustains the hypothesis that the 3020insC mutation in the human NOD2 gene leads to a loss-of-function phenotype.

However, blocking the bioactivity of proinflammatory cytokines, crucial activators of host defence, has proved to be accompanied by an increased susceptibility to infections, especially with Mycobacteria, Salmonellae and fungal pathogens. Multiple mechanisms for these side effects have been proposed, such as inhibition of gamma-interferon production, decreased expression of pattern-recognition receptors, and leucocyte apoptosis. Caution is therefore warranted when these treatments are given to patients with an increased risk for infections. A range of side effects other than infection have been reported.

Almost every hospital was using an antibiotic formulary (97%), sometimes supported by extra restrictions in antibiotic choice (55%). Local practice guidelines (95%) were commonly present, but effective implementation, for example using intranet applications, could be improved (21%). National guidelines had received little attention in the composition process of local guidelines (19%).

Treatment of HIDS is difficult, although simvastatin is beneficial and etanercept might be effective. Studying the treatment of a rare periodic syndrome is complicated by the varying frequency and severity of symptoms and low prevalence. Our aim was to develop a system of clinical observations to evaluate effectiveness of treatment-on-demand. METHODS: Seven fever episodes in three HIDS patients were monitored, with and without administration of etanercept or anakinra. We developed a clinical score, which includes 12 symptoms. In one patient, inflammatory attacks were provoked by vaccination. RESULTS AND CONCLUSIONS: At the onset of an attack, all patients reported a clinical score between 20 and 25. The score was used to quantify severity and define the end of an attack. Reproducible monitoring of inflammatory episodes was difficult, even in this pilot study. The effect of early administration of etanercept was variable. In one patient, a fever episode could be readily provoked within 12 to 24 hours by vaccination. In this patient, the IL-1ra analogue anakinra was more successful in aborting the inflammatory attack than etanercept. We propose that this vaccination model will allow evaluation of treatment-on-demand in a controlled setting.

The objective of this study was to evaluate infection rates and clinical safety of different protocols for human experimental malaria induced by Plasmodium falciparum-infected mosquitoes. METHODS: Thirty nonimmune volunteers were infected by bites of 1-2 or 4-7 Anopheles stephensi mosquitoes infected with the NF54 strain of P. falciparum. RESULTS: A 100 or 50% infection rate was obtained after bites of 4-7 and 1-2 infected mosquitoes, respectively. Median prepatent period was 8.8 days. The most common symptoms after a median incubation time of eight days were headache, malaise/fatigue and fever. There was no significant difference in clinical and parasitological presentation between groups infected by 4-7 or 1-2 mosquitoes. Delay of treatment by maximally 48 hours after the first positive thick smear was generally well tolerated but fever was higher and more frequently observed. The most prominent laboratory abnormality was uncomplicated thrombocytopenia. Two volunteers with parasitaemia developed psychiatric side effects after chloroquine treatment. CONCLUSION: With stringent inclusion criteria, close monitoring and immediate administration of treatment upon detection of parasitaemia, experimental human malaria challenges can be considered safe and generally well tolerated.

To further complicate the efficiency of the residency programme, about 20% of the residents who became internists did not finish within six years, but had a delay of two years due to combined internal medicine/PhD tracks (the training for internist/clinical investigator). In another 20% there is a delay of six to 12 months due to part-time training tracks as well as to (multiple) pregnancies of female residents and parental leave of both sexes.

The purpose of this study was to measure the agreement between the evaluations of chronically fatigued patients by physicians using a CFS protocol and by researchers using computerised questionnaires. METHODS: The sample consisted of 516 patients referred to an internal medicine outpatient clinic with complaints of chronic fatigue. Retrospectively the medical records and the computerised questionnaires were checked separately and compared to see whether the criteria for diagnosis of CFS had been met. In addition, the reasons for not diagnosing CFS were evaluated. RESULTS: Agreement between the physicians' and the researchers' evaluations was 84%. Disagreement mostly concerned severity of fatigue and functional impairment, or premorbid exclusion criteria. A physical cause for the chronic fatigue was only found in 3% of the cases. CONCLUSIONS: For physicians, questionnaire assessment may be complementary to the CFS protocol in optimising the process of diagnosing CFS.

Administration of immunoglobulins is a well-established treatment to reduce the frequency and severity of these infections. However, in patients with anti-IgA antibodies or side effects to previous immunoglobulin substitution therapy, administration of immunoglobulins may lead to anaphylactoid reactions. OBJECTIVE: To describe the feasibility of immunoglobulin substitution therapy in patients with anti-IgA antibodies or side effects to previous immunoglobulins. METHODS: A retrospective study was conducted in two university hospital outpatient clinics. Fourteen patients with common variable immunodeficiency were found to have circulating anti-IgA antibodies or have experienced severe reactions to previously administered blood products. RESULTS: In eight out of 15 patients side effects to immunoglobulins and/or blood transfusions had occurred previously. In four patients these reactions were due to anti-IgA antibodies. No side effects were observed when human immunoglobulin 16% was given by subcutaneous infusion. In all patients with anti-IgA antibodies, as well as in those without, subcutaneous immunoglobulins were well tolerated. In some patients antibodies disappeared and therapy could be changed into intravenous immunoglobulin administration. CONCLUSIONS: Patients with serious side effects to previous immunoglobulin therapy and/or blood transfusions can be safely treated with subcutaneous immunoglobulins and, if necessary, with intravenous immunoglobulins at a later point in time.

METHODS: Five female patients were eligible to receive oral granisetron for one month (1 mg a day for the first two weeks and 2 mg a day for the second two weeks). The patients had to be between 18 and 65 years of age and suffering from CFS according to the CDC criteria. The effect was assessed by pre- and post-testing, using validated instruments designed to assess the different dimensions of CFS. Treatment response was also evaluated by visual analogue scales (VAS) for fatigue. Analysis was based on intention to treat. RESULTS: Treatment with granisetron resulted in significant improvement in fatigue severity and functional impairment. Activity level showed no significant increase. CONCLUSION: The promising results of this study have encouraged us to perform a placebo-controlled, double-blind study to evaluate the efficacy of 5-HT3 receptor antagonists in the treatment of CFS.

We describe a family with four hyper-IgE syndrome patients (38, 37, 30 and 7 years old), in which we investigated the cytokine response to both specific and non-specific stimulation. METHODS: Whole blood from patients and volunteers was stimulated for either 24 or 48h at 37 degrees C with heat-killed Staphylococcus, C. albicans or a combination of IL-12 and IL-18. Cytokine concentrations in the plasma were measured by specific radioimmuno-assays or ELISA. RESULTS: Serum IgE ranged from 5,000 to 16,670 IU/ml, and neutrophil chemotaxis was normal in all four patients. Tumour necrosis factor, interleukin (IL)-1beta, IL-6 and IL-8 production after stimulation of whole-blood cultures with lipopolysaccharide or heat-killed S. aureus did not differ between the adult patients and four healthy controls. In contrast, when blood from patients and controls was stimulated with heat-killed S. aureus or C. albicans, a severe imbalance towards a Th2 phenotype was found, with 10- to 30-fold reduction in the IFNgamma/IL-10 ratios in the hyper-IgE syndrome patients. The IFNgamma production in the patients was less severely impaired when blood was non-specifically stimulated with a combination of IL-18 and IL-12. CONCLUSION: In this family with hyper-IgE syndrome, the imbalance in the Th1/Th2 cytokine production may have been involved in the pathogenesis of the recurrent infections and/or chronic eczema characteristic of this disease.

Although immunoglobulin substitution largely abolished life-threatening respiratory tract infections, considerable infectious and non-infectious morbidity was still encountered in these patients. Almost all patients suffered from chronic or recurrent upper and lower airway infections, mainly caused by Haemophilus influenzae and pneumococci. The lower respiratory tract infections led to cumulative damage to the respiratory tract, especially in XLA patients. Also the incidence of infections outside the respiratory tract (giardiasis, Campylobacter jejuni infections) was more common in XLA patients than in CVID patients. Nodular lymphoid hyperplasia was only found in CVID. A variety of other non-infectious complications were seen especially in CVID. Neoplastic complications occurred in nine patients (two cases of thymoma, two colorectal cancer, one gastric carcinoma, two haematological malignancies, two cases of skin cancer). Six patients died (five XLA patients and one CVID patient, from infectious and non-infectious causes).
