Circulating CRP Levels Are Associated with Epicardial and Visceral Fat Depots in Women with Metabolic Syndrome Criteria.

Sexual dimorphism accounts for significant differences in adipose tissue mass and distribution. However, how the crosstalk between visceral and ectopic fat depots occurs and which are the determinants of ectopic fat expansion and dysfunction remains unknown. Here, we focused on the impact of gender in the crosstalk between visceral and epicardial fat depots and the role of adipocytokines and high-sensitivity C-reactive protein (hs-CRP). A total of 141 outward patients (both men and women) with one or more defining criteria for metabolic syndrome (MetS) were consecutively enrolled. For all patients, demographic and clinical data were collected and ultrasound assessment of visceral adipose tissue (VFth) and epicardial fat (EFth) thickness was performed. Hs-CRP and adipocytokine levels were assessed by enzyme-linked immunosorbent assay (ELISA). Men were characterized by increased VFth and EFth (p-value < 0.001 and 0.014, respectively), whereas women showed higher levels of adiponectin and leptin (p-value < 0.001 for both). However, only in women VFth and EFth significantly correlated between them (p = 0.013) and also with leptin (p < 0.001 for both) and hs-CRP (p = 0.005 and p = 0.028, respectively). Linear regression confirmed an independent association of both leptin and hs-CRP with VFth in women, also after adjustment for age and MetS (p = 0.012 and 0.007, respectively). In conclusion, men and women present differences in epicardial fat deposition and systemic inflammation. An intriguing association between visceral/epicardial fat depots and chronic low-grade inflammation also emerged. In women Although a further validation in larger studies is needed, these findings suggest a critical role of sex in stratification of obese/dysmetabolic patients.

The grandfather's fever.

An 86-year-old Caucasian man had prior episodes of fever (up to 38 °C), mild abdominal pain, tachycardia, and malaise in the last 3 months, lasting 2-3 days. He never suffered from abdominal or chest pain, rash, or arthralgia. Major causes of fever were excluded (pulmonary, urinary, abdomen, skin infections, neoplasms, and major rheumatologic disorders). The patient was native of Altamura with a family history of familial Mediterranean fever (FMF). The genetic testing confirmed the presence of MEFV gene variants c.442G>C (E148Q) on exon 2 and c.2282G>A (R761H) on exon 10, all in heterozygosity. Mildly elevated serum transaminases suggested an ongoing form of FMF hepatitis on nonalcoholic liver steatosis. The patient started colchicine 1 mg/day that induced symptom control and normalization of inflammatory markers, hyperbilirubinemia, and markers of cholestasis. Symptoms of FMF can appear at any age in life and our patient represents a very late-onset clinical case. The Apulian region has a consistent clustering of MEFV variants and FMF families with affected individuals in multiple consecutive generations. Families show unique clinical features and rare signs of secondary amyloidosis without kidney damage. Genetic and environmental bases of this phenotypic variant are under scrutiny. Colchicine lifetime remains the mainstay of treatment in FMF patients. KEY POINTS: • Familial Mediterranean fever (FMF) is the most frequent hereditary monogenic recurrent fever syndrome, and symptoms can appear at any age in life. • Late-onset FMF approaches 30% in late adulthood, but in general, onset of FMF after the age of 40 (late onset FMF) is rare, usually associated with M694V heterozygosity. • In a local cluster of FMF families (Altamura, Puglia, Southern Italy), we report a very late-onset FMF (variants E148Q, R761H) in an 86-year-old patient with a positive family history of FMF in two generations of descendants. • While lifetime colchicine remains the mainstay of treatment in FMF patients, prospective studies need to identify the characteristics of several phenotypic variants accounting for (very)-late onset FMF.

[Diagnosis of Alport syndrome]. / Il percorso diagnostico della sindrome di Alport e della malattia a membrane basali sottili.

Diagnosis of Alport syndrome or Thin basement membrane disease is suggested first of all by the clinical picture, the presence of neurisensorial hypoacusia and/or ocular abnormalities, and the family history which should be as accurate as possible involving the largest number possible of family members to recognize the transmission modalities, i.e. X-linked or autosomal. Renal biopsy remains the main tool to confirm the diagnosis and requires electron microscopy observation and collagen IV alpha chains investigation on renal tissue by means of specific antibodies. Skin biopsy is a useful and less invasive tool in families with X-linked Alport syndrome and can substitute renal biopsy in childhood as well as in patients with contraindication to renal biopsy. Confocal microscopy is mandatory to reduce the risk of false negative results in patients with segmental expression of alpha chains. Genetic analysis is at present indicated for studying subjects at risk for family planning or possible kidney donation but new techniques (Next Generation Sequencing) might increase their use in clinical practice.
