Background:Spondyloarthritis (SpA) and Familial Meditaerranean fever (FMF) may co-exist in certain populations, and have some overlapping manifestations (oligo-arthritis, hip involvement). Their association may impact disease phenotype and may affect disease management.Objectives:To evaluate the association of SpA and FMF and its impact on disease phenotype and management.Methods:A systematic literature search was conducted with the keywords spondyloarthritis and familial mediterranean fever from Janurary 1990 to January 2020 in PubMed and using manual cross-reference methods.Results:The search retrieved 74 articles, out of which 37 articles were relevant to the study question; most of the articles were case reports, with some large cohort studies of FMF and SpA (Flowchart in Figure 1).In large FMF cohorts, the prevalence of SpA was higher compared to the general population (7.5-13%, OR around 10). M694V was a risk factor for SpA. These FMF-SpA patients were older at diagnosis, had lower fever attacks, and higher disease duration, inflammatory back pain, chronic arthritis, enthesopathy, persistent inflammation and higher resistance to Colchicine. In case series, they were responsive to anti-TNF therapy.In large SpA cohorts, MEFV mutation, particularly M694V, was found in 15-35% (even without associated FMF). In most cohorts, MEFV mutation carriers didn’t have any distinct disease phenotype, except for some reports of higher ESR, more hip involvement, higher BASFI and higher BASDAI. Genome-wide association studies and case reports suggest an implication for IL-1 and thus a role for Anakinra therapy in these patients.Conclusion:In FMF or SpA patients with resistance to conventional therapy, the evaluation of disease association should be performed as it may have significant impact on disease management.References:[1]Li et al, Plos Genetics 2019.

Exon 10

Familial mediterranean fever (FMF) is an inherited autoinflammatory disorder characterized by recurrent episodes of fever and painful inflammation involving the intra-abdominal organs, the lungs and the joints, which is highly prevalent in specific ethnic groups including the Iranians. We report a 12-year-old boy from Iran, with a clinical history of recurrent fever. Based on the suggestive clinical data, mutational analysis revealed the presence of the novel c.1945C>T heterozygous variant in exon 10, which leads to a leucine to phenylalanine change at position 649 of the protein. The mutation was inherited from the mother. This novel mutation lies in exon 10 of the MEFV gene, which encodes for a domain called B30.2-SPRY, located in the C-terminal region of the pyrin protein and contains the most frequent mutations associated with FMF. The present report expands the spectrum of MEFV gene mutations associated with FMF. The uniqueness of this study, compared with other published case reports, consists in the new mutation found in the MEFV gene. In fact, new mutations in this gene are of high interest, in order to better understand the role of this gene in autoinflammation.

Mediterranean Fever

The objective of this study was to assess the prevalence of the Mediterranean FeVer ( MEFV) gene mutations in systemic lupus erythematosus (SLE) patients and their effect on organ involvement, as well as disease activity and severity. The frequencies of three familial Mediterranean fever-related MEFV gene mutations ( M694V, V726A and E148Q) were investigated in 70 SLE patients. Organ involvement, Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) damage index and Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) scores were correlated with mutation carriage. Eleven of 70 patients (15.7%) were found to carry an MEFV mutation. A single patient harbored two mutations, E148Q and V726A, without overt familial Mediterranean fever while the rest were heterozygous carriers. Four of the 11 carried an M694V mutation, four carried V726A and two carried E148Q. The majority of MEFV mutation carriers were Sephardic while non-carriers were mainly of Ashkenazi origin (72.7% vs. 45.7% and 47.4% vs. 9.1%, respectively, p = 0.02). SLE onset was significantly earlier in MEFV carriers (27.6 ± 9.7 vs. 38.2 ± 15.5 years, in carriers vs. non-carriers, p = 0.02). Hematologic and serologic parameters were comparable among mutation carriers and non-carriers. Febrile episodes were more common among MEFV mutation carriers (45.4% vs. 15.2%, p = 0.035) and there was a trend for excess episodes of pleuritis as well (54.5% vs. 23.7%, p = 0.06 in carriers vs. non-carriers, respectively). The frequency of secondary anti-phospholipid antibody syndrome was equivalent among the groups. Conversely, compound urinary abnormalities and renal failure was not observed among MEFV carriers yet was present in 33.4% and 18.6% of non-carriers ( p = 0.027 and 0.19, respectively). SLICC damage index and SLEDAI activity index did not differ significantly between the groups. MEFV mutation carriage appears to modify the SLE disease phenotype in that it contributes to an excess of inflammatory manifestations such as fever and pleuritis on the one hand, while thwarting more severe renal involvement on the other.

Chiari malformations (Types I–IV) are abnormalities of the posterior fossa that affect the cerebellum, brainstem, and the spinal cord with prevalence rates of 0.1%–0.5%. Case reports of familial aggregation of Chiari malformation, twin studies, cosegregation of Chiari malformation with known genetic conditions, and recent gene and genome-wide association studies provide strong evidence of the genetic underpinnings of familial Chiari malformation. The authors report on a series of 3 family pairs with Chiari malformation Type I: 2 mother-daughter pairs and 1 father-daughter pair. The specific genetic causes of familial Chiari malformation have yet to be fully elucidated. The authors review the literature and discuss several candidate genes. Recent advances in the understanding of the genetic influences and pathogenesis of familial Chiari malformation are expected to improve management of affected patients and monitoring of at-risk family members.

Recurrent Aseptic Meningitis

Abstract Background Familial Mediterranean fever (FMF) is an autosomal recessive, auto-inflammatory disease, presenting with recurrent bouts of fever and polyserositis. FMF has been associated with central nervous system (CNS) manifestations such as Headache and Myalgia. The occurrence of other forms of nervous system involvement is rare, including seizures, sinus vein thrombosis, pseudotumor cerebri and more. There are only few case reports of aseptic meningitis due to FMF. Case presentation We present the case of a 14 year-old girl diagnosed with FMF, who experienced recurrent episodes of severe headache and aseptic meningitis while on maximal dose of colchicine therapy. She had a dramatic response to anakinra with symptoms resolving completely within a few days without recurrence. Subsequently, we identified seven cases in the literature describing recurrent aseptic meningitis in patients with underlying FMF; all showed response to colchicine treatment, without treatment failure. Conclusion Our case suggests a role for Interleukin 1 (IL-1) antagonists for cases of CNS involvement secondary to FMF in patients who fail to respond to colchicine, and might imply that anakinra could be effective in other auto-inflammatory diseases with CNS involvement.

The Individual

Genome-wide association studies (GWAS) promised to translate their findings into clinically beneficial improvements of patient management by tailoring disease management to the individual through the prediction of disease risk. However, the ability to translate genetic findings from GWAS into predictive tools that are of clinical utility and which may inform clinical practice has, so far, been encouraging but limited. Here we propose to use a more powerful statistical approach that enables the prediction of multiple medically relevant phenotypes without the costs associated with developing a genetic test for each of them. As a proof of principle, we used a common panel of 319,038 SNPs to train the prediction models in 114,264 unrelated White-British for height and four obesity related traits (body mass index, basal metabolic rate, body fat percentage, and waist-to-hip ratio). We obtained prediction accuracies that ranged between 46% and 75% of the maximum achievable given their explained heritable component. This represents an improvement of up to 75% over the phenotypic variance explained by the predictors developed through large collaborations, which used more than twice as many training samples. Across-population predictions in White non-British individuals were similar to those of White-British whilst those in Asian and Black individuals were informative but less accurate. The genotyping of circa 500,000 UK Biobank participants will yield predictions ranging between 66% and 83% of the maximum. We anticipate that our models and a common panel of genetic markers, which can be used across multiple traits and diseases, will be the starting point to tailor disease management to the individual. Ultimately, we will be able to capitalise on whole-genome sequence and environmental risk factors to realise the full potential of genomic medicine.

Early Case

Peripartum cardiomyopathy (PPCM) is a rare type of cardiomyopathy. PPCM is a potentially life-threatening pregnancy-associated disease that typically arises in peripartum period and is marked with left ventricular (LV) dysfunction and heart failure. The cause of PPCM remain unclear, but several mechanisms have been proposed ehich indices a potentially multi-factorial etiology. Early case reports identified overlap between familial dilated cardiomyopathy (DCM) and PPCM, although the degree of overlap is largely unknown. Many evidence supporting a contribution from gene mutations in PPCM includes genome-wide association studies, familial occurrence, variable prevalence among different regions and ethnicities, and more recent investigations of panels of genes for mutations among women with PPCM. Although the true incidence of genetic cardiomyopathy is not yet known among women with PPCM, there is substantial evidence demonstrating that genetic contribution to their condition.

The homozygous M694V mutation in the MEFV gene may cause an augmented response to the streptococcal infection that plays a role in the development of APSGN and PAN. Both clinical manifestations may occur simultaneously after streptococcal infection in a child who is previously healthy but carries a MEFV mutation.
