RESUMEN
A 54-year-old man with a university degree was admitted to our hospital because of a two-year history of progressive dementia. He had familial sensorineural hearing loss and had been treated for epilepsy since his 30s. On admission, he showed severe dementia and parkinsonism without fever or skin rash. Systemic inflammation was evident, and the CSF cell count and IL-6 level were elevated to 53/µl and 307â |pg/ml, respectively. Brain MRI demonstrated diffuse brain atrophy. More detailed anamnesis revealed a history of rheumatoid arthritis in childhood and aseptic meningitis in his 20s. Genetic examination for autoinflammatory diseases demonstrated compound heterozygotic mutations in the NLRP3 gene, causing cryopyrin-associated periodic fever syndrome (CAPS). This case was atypical CAPS presenting as early-onset progressive dementia, without recurrent fever or urticaria-like eruption which are usually seen in this disease.

Cold hypersensitivity in the hands and feet (CHHF) is a protective or predisposing factor for many diseases; however, the relationship between CHHF and erectile dysfunction (ED) remains unclear. We aimed to investigate associations between CHHF and ED among young men of Southeast Asian origin. In this cross-sectional study, sexually active Taiwanese men aged 20-40 years were enrolled via an online questionnaire comprising general demographic information, comorbidities, subjective thermal sensations of their hands and feet in the past 6 months, and their erectile function using the International Index of Erectile Function-5 (IIEF-5). Participants who reported cold sensation of hands and feet were classified to have CHHF; those with IIEF-5 score ≤ 21 were considered to have ED. Total 54.2% and 27.9% of participants had ED and CHHF, respectively. Men with CHHF were significantly younger, had lower body mass index and IIEF-5 scores (p < 0.001), and a lower prevalence of diabetes mellitus (p = 0.033) along with higher prevalence of ED, psychiatric disorders, and insomnia (p < 0.001). After adjusting for predisposing factors of ED, CHHF (odds ratio 1.410, 95% confidence interval 1.159-1.714; p = 0.001) remained an independent predictor of ED. Thus, CHHF is independently associated with ED, affecting more than a quarter of young Taiwanese men. Autonomic dysregulation and subclinical endothelial dysfunction may be common pathophysiologies of CHHF and ED.

Muckle-Wells syndrome (MWS) is a genetic periodic fever syndrome characterised by urticaria, fever and malaise starting in childhood with the development of perceptive hearing loss and risk of amyloidosis later in life.Patient A, in his 60s, was referred to a nephrologist because of glomerular haematuria and elevated erythrocyte sedimentation rate. He appeared to have periodic fevers since childhood, skin changes in cold circumstances and progressive deafness since he was 30 years of age. Genetic analysis revealed a pathogenic variant in the NLRP3 gene compatible with MWS. Treatment with anakinra (interleukin 1 antagonist) improved his symptoms, but only mild episodic arthralgia remained. Glomerular erythrocyturia diminished during treatment, supposing a relation between MWS and haematuria.This case report shows that rare genetic fever syndromes starting from early childhood can still be diagnosed in adult patients, with important therapeutic consequences. Symptoms can be relieved and amyloidosis with potential renal failure may be prevented.

OBJECTIVES: NLRP3-associated autoinflammatory disease (NLRP3-AID) is a spectrum of autosomal dominant inherited diseases associated with NLRP3 gene mutations. Reports of Chinese NLRP3-AID cases are limited to date. In the present study, we aim to describe the phenotype and genotype of a cohort of Chinese adult NLRP3-AID patients METHODS: This single-center study included sixteen adult patients diagnosed with NLRP3-AID at Department of Rheumatology, Peking Union Medical College Hospital from April 2015 to September 2021. Whole-exome sequencing using next-generation sequencing was performed in each patient. Clinical data and mutational information were compared with a European cohort. RESULTS: The median age of disease onset was 16 (0-46) years old, and adult-onset was observed in 4 patients (25%). The median time of diagnosis delay was 20 (0-39) years. Five patients (31.3%) had family history of similar symptoms. The most common clinical manifestations were recurrent fever (93.8%), arthralgia/arthritis (81.3%), skin rash (75%), myalgia (62.5%), and central nervous system manifestations (50%). Heterozygous NLRP3 variants detected in these patients were p.T348M (n = 4, 25%), Q703K, V70M, K129R, M116I, P38S, V442I, D303G, G326E, A439V, K829T, L632F and V198M (n = 1, separately). All the variants were missense mutations. CONCLUSIONS: We reported the largest case series of Chinese adult NLRP3-AID patients. The distinct symptoms of NLRP3-AID patients suggest the heterogeneity of disease. P38S, M116I, K129R, V442I and K829T were identified as novel NLRP3 variants. These data expand the clinical phenotypic and genotypic profiles of NLRP3-AID. Key Points ⢠We characterized the clinical and genetic features of sixteen Chinese adult NLRP3-AID patients. ⢠Thirteen NLRP3 gene variants were confirmed in this cohort, and P38S, M116I, K129R, V442I and K829T were identified as novel variants. ⢠Clinical data and mutation information were compared with a European cohort. ⢠We hope these data would expand the phenotypic and genotypic profile of NLRP3-AID and raise the awareness of early diagnosis and accurate treatment among rheumatologists.

El síndrome periódico asociado a la criopirina es una enfermedad rara y probablemente infradiagnosticada. Se presenta con manifestaciones sistémicas, entre ellas oftalmológicas, muy diversas, por lo que su diagnóstico supone un reto para el clínico. Presentamos el caso de una niña de 4 años en la que la identificación de papiledema en el examen oftalmológico constituyó el signo guía para el diagnóstico de síndrome periódico asociado a la criopirina. Pretendemos así concienciar sobre esta enfermedad de graves implicaciones y cuyo diagnóstico precoz resulta esencial para los afectados, para que sea tenido en cuenta con mayor frecuencia como diagnóstico diferencial (AU)

Periodic fever syndromes (PFS) are a group of autoinflammatory diseases characterized by repeated febrile episodes and systemic inflammation. The most common monogenic periodic fever syndromes are familial Mediterranean fever, mevalonate kinase deficiency/hyper immunoglobulin D syndrome, cryopyrin-associated periodic syndrome, and tumor necrosis factor receptor-associated periodic syndrome. Although fever is the predominant feature of PFS, other systems, including the cardiovascular system, may be involved in the disease process. This review focuses on cardiovascular risks and issues in monogenic PFS. Cardiovascular involvement may occur as a disease manifestation, association, or result of complications or a drug's adverse effects in monogenic PFS. Pericarditis seems to be a feature of PFS. Patients with recurrent pericarditis or pericarditis resistant to conventional treatment should be evaluated for PFS. Amyloidosis is the most severe complication of PFS, increasing the risk of cardiac morbidity. Furthermore, ongoing inflammation may result in early atherosclerosis. Therefore, assessing cardiovascular risks in PFS patients should be considered a part of routine care. Key points ⢠Pericarditis is the most common cardiac involvement of monogenic periodic fever syndromes (PFS), while some forms may present with myocarditis. ⢠Amyloidosis, the most significant complication of PFS, may lead to deterioration in cardiac functions. ⢠Ongoing inflammation in PFS may result in endothelial dysfunction and atherosclerosis. ⢠Effective control of inflammation and reducing concomitant risk factors such as obesity, diabetes mellitus, and hypertension could improve cardiovascular outcomes in PFS patients.

A healthy 12-month-old female presented with relapsing and remitting urticaria since birth that was resistant to treatment with antihistamines. A thorough history revealed extensive rheumatic disease on the father's side of the family, and subsequent genetic testing was positive for a missense variant of NLRP3, indicating cryopyrin-associated periodic fever syndrome (CAPS). CAPS encompasses a spectrum of diseases, all related to a defect in the same gene; manifestations vary in severity and presentation, but most are associated with recurrent rash and fever. Because the patient's only presenting symptom was rash, this case highlights the importance of having a high index of suspicion for cryopyrin-associated periodic fever syndrome in infants with persistent, early urticaria.

Familial cold autoinflammatory syndrome (FCAS) is a rare phenotype of cryopyrin-associated periodic syndrome (CAPS) and is characterized by repetitive systemic inflammation triggered by cold stimulation. Recently, we treated a 13-year-old female with FCAS/CAPS scheduled to undergo removal of an impacted tooth. To minimize perioperative heat loss, a forced-air warming system was utilized to prewarm the patient for 10 minutes before induction of general anesthesia. The patient's core and peripheral temperatures were monitored with axillary, superficial temporal artery, and rectal thermometers. The difference in temperatures at these 3 locations decreased to 0.4° C within 60 minutes as a result of the forced-air warming system before induction. Perioperative use of the warming system successfully prevented the occurrence any significant redistribution hypothermia and any symptoms of FCAS/CAPS.

OBJECTIVE: To report our five-years experience on the use of NLRP3 inflammasome functional assays in the differential diagnosis of Brazilian patients with a clinical suspicion of CAPS. PATIENTS AND METHODS: The study included 9 patients belonging to 2 families (I, II) and 7 unrelated patients with a clinical suspicion of AID according to Eurofever/PRINTO classification, recruited between 2017 and 2022. The control group for the NLRP3 functional assay consisted of 10 healthy donors and for the CBA cytokines measurement of 19 healthy controls. Patients underwent clinical evaluation, genetic and functional analysis. RESULTS: All members of the family I received the diagnosis of Muckle-Wells Syndrome (MWS), carried the NLRP3 Thr348Met variant and resulted positive for the functional assay. The 2 patients of the family II resulted negative for the mutational screening but positive for the functional assay compatible with a MWS clinical phenotype. In 2 unrelated patients with NLRP3 mutations, including a novel mutation (Gly309Val, Asp303His), a positive functional test confirmed the clinical diagnosis of NOMID. 3 unrelated MWS and 1 FCAS patients resulted negative to the genetic screening and positive for the functional test. One patient with a FCAS-like phenotype harbored the NLRP12 His304Tyr variant confirming the diagnosis of FCAS2. CONCLUSION: The NLRP3 inflammasome functional assay can assist the clinical diagnosis of CAPS even in patients with unknown genetic defects.

OBJECTIVE: Cryopyrin-associated periodic syndrome (CAPS) is a rare but treatable inherited autoinflammatory condition including familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS) and chronic infantile neurologic cutaneous articular syndrome (CINCA). Our objective was to describe the main features of CAPS AA amyloidosis (AA-CAPS) associated and the efficacy of IL-1 inhibitors in this indication. METHODS: Retrospective study in France associated with a systematic literature review. RESULTS: Eighty-six patients were identified: 23 new French cases and 63 from the literature, with a median age at amyloidosis diagnosis of 39 years old. CAPS subtypes were MWS (n = 62), FCAS (n = 9), frontier forms between MWS and FCAS (n = 12) and between CINCA and MWS (n = 3). NLRP3 had been sequenced in 60 patients (70%) and the most frequent mutation was R260W (60%). Three AA-CAPS patients displayed somatic NLRP3 mutations. Death occurred in 35 patients (41%), none of whom having ever received IL-1 inhibitors. Twenty-eight patients (33%) received IL-1 inhibitors, with a >50% decrease in proteinuria in 89% of cases. CONCLUSION: AA amyloidosis can occur in nearly all CAPS subtypes. IL-1 inhibitors are effective, underlining the necessity of an early diagnosis of CAPS in order to start this treatment as soon as possible among AA-CAPS patients.

BACKGROUND: Cryopyrin-Associated Periodic Syndrome (CAPS) is a variety of clinical variants of autoinflammatory diseases. The pathology is based on a mutation in the NLRP3 gene encoding the cryopyrin protein, which leads to the uncontrolled production of interleukin-1ß. Particular attention should be paid to the rarity of this disease and the lack of clinical knowledge about it in therapeutic and rheumatological practice, which leads to an erroneous diagnosis and the appointment of ineffective treatment for a long time, leading to the progression of the disease and disability of the patient. CASE PRESENTATION: This article describes a clinical case of this disease. The first manifestations of the disease in a woman appeared from the age of 2 years, in the form of a rash and fever. Since school age, there have been signs of arthritis. By the age of 24, sensorineural hearing loss and pain in the spine were evident. The disease occurred under the clinical manifestations of spondyloarthritis. Its treatment with anti-inflammatory therapy did not give a stable result. CONCLUSION: From the analysis, we can conclude that patient M. from early childhood suffers from a severe Neonatal-onset Multisystem Inflammatory Disease of a genetic nature. For a long time, the patient was diagnosed with ankylosing spondylitis, and appropriate treatment was carried out without significant success. The correct diagnosis of CAPS was made only in 2018. This patient has conditions of both CAPS and AS together, which is a very rare association in rheumatological practice. The only treatment method that could stop the manifestations of the disease and prevent life-threatening kidney damage (amyloidosis) is the use of genetically engineered biological drugs, i.e., IL-1ß inhibitors. The only drug of this group registered in Russia is canakinumab (Ilaris®). From the moment of diagnosis to the present day, the patient is treated with the genetically engineered drug canakinumab (Ilaris®) at a dose of 150 mg once every 8 weeks. 6 months after taking the drug, the patient went into complete clinical and laboratory remission.

A 20-year-old man presented with recurrent subdural haemorrhages on a background of progressive sensorineural hearing loss, juvenile idiopathic arthritis and intracranial hypertension of unknown cause. His mother had a similar previous history. They both had a persistently mildly elevated serum C reactive protein. Repeat lumbar punctures identified persistently elevated intracranial pressure and mild pleocytosis. A dural biopsy showed necrotising pachymeningitis with granulomatous vasculitis. The underlying cause in both patients was a cryopyrin-associated periodic syndrome. We discuss its varied phenotype and how clinicians need to be aware of this treatable genetic condition to facilitate early treatment and to prevent accumulation of disability.

The co-existence of an autoinflammatory syndrome with a demyelinating disorder is a very rare occurrence raising the question whether there is a pathophysiological connection between them. We describe the case of a man with symptoms of cryopyrin-associated periodic syndrome (CAPS) since infancy who later developed multiple sclerosis (MS). As CAPS was genetically confirmed, the inhibition of interleukin-1 (IL-1) with anakinra led to a swift resolution of the CAPS symptoms and also, in combination with teriflunomide, to a clinical and imaging improvement of MS. In vitro studies showed that, upon a CAPS flare, the patient's peripheral neutrophils released neutrophil extracellular traps (NETs) decorated with IL-1ß, while NET release was markedly decreased following anakinra-induced remission of CAPS. Taking into account the growing evidence on the involvement of IL-1ß in experimental models of MS, this rare patient case suggests that the role of neutrophils/NETs and IL-1ß in MS should be further studied.

The cold-sensitivity constitution (CSC), termed "Hiesho" in Japanese, is a woman-specific cold sense of peripheral sites. The etiology of and criteria for CSC are not yet well established. We defined CSC as temperature gradient > 6ËC between body surface and core, and investigated the autonomic nervous activity by measuring heart rate variability and the vascular endothelial function by determining reactive hyperemia index (RHI) in 43 healthy premenopausal women, aged 18-47 years. Twenty five women had CSC during both the follicular and luteal phases of their menstrual cycles (sustained-CSC group), 8 women did not show CSC during both phases (non-CSC group), and the remaining 10 women showed CSC in either menstrual phase (occasional CSC). To identify the pathophysiological bases of CSC, we compared the sympathetic nervous activity and vascular endothelial function between sustained-CSC and non-CSC. We thus found that sympathetic nervous activity was higher among the sustained-CSC group (p = 0.042) during the follicular phase, compared with the non-CSC group, while the RHI was similar in both groups. Furthermore, the sympathetic nervous activity was similar between the sustained-CSC women aged ≥ 40 years (n = 10) and those aged < 40 years (n = 15) during either menstrual phase, whereas the RHI of the women aged < 40 years was lower during the follicular phase (p = 0.045), compared with the women aged ≥ 40 years. In conclusion, CSC is associated with sympathetic nervous hyperactivity in premenopausal women, and vascular endothelial dysfunction is also involved in CSC among younger women.

PURPOSE: To report a case of uveitis and papillitis in a patient with cryopyrin-associated periodic syndrome. METHODS: Case report. A 44-year-old white woman with a long history of inflammatory arthritis, diffuse erythematous rashes and hives, and hearing loss was referred to the Massachusetts Eye Research and Surgery Institution for an evaluation of chronic ocular inflammation. She was diagnosed with bilateral papillitis and uveitis after a comprehensive eye examination, which included dilated fundoscopy, optic nerve ocular coherence tomography, fluorescein angiography, indocyanine green angiography, and B-scan ultrasonography. She was later diagnosed with cryopyrin-associated periodic syndrome, an interleukin-1-driven autoimmune disease, as confirmed by genetic testing. Soon after starting treatment with anakinra, a human interleukin-1 receptor antagonist, she experienced rapid improvement of her ocular and systemic symptoms, including rash, uveitis, and arthritis. RESULTS: Cryopyrin-associated periodic syndrome-associated ocular inflammation in remission with anakinra 100-mg daily subcutaneous injection. CONCLUSION: Anakinra is a very effective treatment for both cryopyrin-associated periodic syndrome and cryopyrin-associated periodic syndrome-associated ocular inflammation.
