Background: Eosinophilic fasciitis (EF) is a rare disease characterized by scleroderma-like skin, inflammation of deep muscle fascia, hypergammaglobulinemia, peripheral eosinophilia, and elevated erythrocyte sedimentation rate.

Objectives: To present our experience in diagnosis and treatment of seven biopsy-proven EF patients in a large tertiary medical center.

Methods: We screened all patients who were admitted to our tertiary medical center and diagnosed with EF by tissue biopsies from January 2000 to January 2016. We analyzed relevant patient files regarding diagnosis, treatment, and outcome parameters. A comprehensive framework was presented based on the results of our observations and the corresponding literature.

Results: We identified seven patients (six males; one child). Mean age at diagnosis was 37.4 years (range 10–67 years). Underlying autoimmune disorders were observed in three patients (42.8 %). Disease anatomical distribution was noted in lower and upper limbs (85.7% and 57.1%, respectively) as well as neck and shoulders (14.3% each). Three patients (42.8%) had a history of initial misdiagnosis. The mean time period from first clinical presentation to histopathological diagnosis was 150.3 days (range 16–602 days). Treatment included oral glucocorticoids (71.4%), pulse methylprednisolone (14.2%), and methotrexate (42.8%). Recovery from symptoms related to EF was observed in six patients.

Conclusions: Diagnosis of EF is primarily based on clinical and histopathological findings. As eradication of this disease can be expedited with early treatment, it is important to increase awareness in the medical community.

A 47 year old man presented with a combination of dry mouth and lightheadedness while standing. His medical background was unremarkable except for cigarette smoking and hyperlipidemia. Sjögren’s syndrome was ruled out, and he was referred for evaluation of orthostatic hypotension, which by then included syncopal episodes and injuries. Additional symptoms included dry eyes, constipation, reduced sweating, and erectile dysfunction. After excluding medications and structural cardiac abnormalities as causes of orthostatic hypotension, a clinical autonomic evaluation was performed. The pattern of beat-to-beat blood pressure associated with performance of the Valsalva maneuver, and a low plasma norepinephrine level that did not increase in response to standing, established that the orthostatic hypotension was neurogenic. Treatment with an alpha-adrenoceptor agonist and fludrocortisone yielded partial improvement. After systemic diseases involving autonomic failure were excluded, cardiac sympathetic neuroimaging was performed by ¹²³I-metaliodobenzylguanidine (MIBG) scanning. The normal uptake seen in the heart indicated intact post ganglionic sympathetic innervation. There were no signs of central neurodegeneration or peripheral neuropathy. Because of symptoms and signs of both parasympathetic and sympathetic failure without denervation, an autonomic ganglionopathy was considered. A high titer of antibody to the neuronal nicotinic receptor, which mediates ganglionic neurotransmission, was obtained. The diagnosis of autoimmune autonomic ganglionopathy (AAG) was made, and the management strategy shifted to first lowering the antibody burden by plasma exchanges and then instituting chronic anti-autoimmune treatment with rituximab and a low dose of cortiosteroid. The patient showed remarkable improvement.

Background: Postpericardiotomy syndrome (PPS) is characterized by pleuro-pericardial inflammation, which occurs in patients undergoing surgical procedures involving the pleura, pericardium, or both. The syndrome is considered to be immune mediated. However, its pathogenesis is not fully understood. It has previously been demonstrated that the Mediterranean Fever (MEFV) gene, which is associated with familial Mediterranean fever (FMF), has a role in the activation and expression of several inflammatory diseases.

Objectives: To investigate whether carriage of the MEFV mutation may precipitate PPS or affect its phenotype.

Methods: The study population included 45 patients who underwent cardiac surgery and developed PPS. The control group was comprised of 41 patients who did not develop PPS. Clinical and demographic data was collected. The severity of PPS was evaluated. Genetic analysis to determine the carriage of one the three most common MEFV gene mutations (M694V, V726A, E148Q) was performed. The carriage rate of MEFV mutations in patients with and without PPS was compared. Association between MEFV mutation carriage and severity of PPS was evaluated. 

Results: The rate of mutation carriage in the MEFV gene was similar in patients with and without PPS (15.6% in the study groups vs. 29.3% in the control group, P = 0.1937). The rate of mutation carriage in the MEFV gene was significantly lower among patients with severe PPS as compared to patients with mild-moderate PPS (4.8% vs. 25%, P < 0.05).

Conclusions: Carriage of mutations in the MEFV gene is not associated with development of PPS; however, it may affect PPS severity.

 

Primary Sjögren’s syndrome (pSS) is a chronic autoimmune disease mainly affecting exocrine glands. However, a subgroup of patients experiences extraglandular manifestations which worsens disease prognosis. To date evidence based guidelines for the management of pSS are lacking, hence the therapeutic approach is mainly based on expert opinion and data from other connective tissue diseases. In recent years, several studies have explored the efficacy and safety of biologic agents in pSS and after the failure of tumor necrosis factor inhibitors, the attention has been focused on compounds directly targeting B or T lymphocytes. The aim of this review article is to provide an overview of available data about B and T cell targeting in pSS and of future directions based on ongoing trials. 

Background: Pulmonary arterial hypertension (PAH) is a significant consequence of congenital heart disease (CHD). Its presence and severity is associated with increased morbidity and mortality. 

Objectives: To evaluate the clinical and demographic characteristics of adults with congenital heart diseases (ADCHD) and PAH at a single center. 

Methods: A prospective registry of all patients with PAH was conducted between 2009 and 2015. 

Results: Thirty-two patients were identified. The mean age at the last visit was 44 years (range 19–77 years). The prevalence of PAH among all ADCHD patients was 6% (95% confidence interval 4.3%–8.4%). A much higher prevalence (53%) was found in patients with Down syndrome. Most patients with PAH had moderate or severe disease. Fifteen patients (47%) were treated with pulmonary vasodilators and 6 (19%) with combination therapy. The average World Health Organization functional class was 2.6. Morbidity included cerebral vascular accident or transient ischemic attack in 22% (mostly in patients with right-to-left shunt) and arrhythmia in 37% of the patients. During a median follow-up of 3.5 years, 5 patients (15.6%) died. Of 13 women with no mental retardation, 11 were or had been married and all had children (between 1 and 13, mean 3.3). 

Conclusions: Patients with congenital heart disease and PAH have significant morbidity and mortality. PAH is more prevalent in patients with Down syndrome. While pulmonary pressure during the reproductive years was not always known, 27% of women with PAH at the time of the study were multiparous.

 

Fevers recurring at a nearly predictable rate every 3–8 weeks are the signature symptom of periodic fever, aphthous stomatitis, pharyngitis, cervical adenitis (PFAPA) syndrome, an acquired autoinflammatory disorder which recurs in association with at least one sign among aphthous stomatitis, pharyngitis, and/or cervical lymph node enlargement without clinical signs related to upper respiratory airways or other localized infections. The disease usually has a rather benign course, although it might relapse during adulthood after a spontaneous or treatment-induced resolution in childhood. The number of treatment choices currently available for PFAPA syndrome has grown in recent years, but data from clinical trials dedicated to this disorder are limited to small cohorts of patients or single case reports. The response of PFAPA patients to a single dose of corticosteroids is usually striking, while little data exist for treatment with cimetidine and colchicine. Preliminary interesting results have been published with regard to vitamin D supplementation in PFAPA syndrome, while inhibition of interleukin-1 might represent an intriguing treatment for PFAPA patients who have not responded to standard therapies. Tonsillectomy has been proven curative in many studies related to PFAPA syndrome, although the evidence of its efficacy is not widely shared by different specialists, including pediatricians, rheumatologists and otorhynolaryngologists.

Background: Biallelic BLM gene mutation carriers are at an increased risk for cancer, including colorectal cancer (CRC). Whether heterozygous BLM gene mutations confer an increased cancer risk remains controversial.

Objectives: To evaluate CRC and endometrial cancer risk in BLM heterozygous mutation carriers.

Methods: Jewish Ashkenazim at high risk for colon or endometrial cancer and endometrial cancer cases unselected for family history were genotyped for the BLM^Ash predominant mutation.

Results: Overall, 243 high-risk individuals were included: 97 men CRC patients (55.12 ± 12.3 years at diagnosis), 109 women with CRC (56.5 ± 13.7 years), 32 women with endometrial cancer (58.25 ± 13.4 years) and 5 women with both CRC and endometrial cancer. In addition, 120 unselected Ashkenazi women with endometrial cancer (64.2 ± 11.58 years) were genotyped. The BLM^Ash mutation was present in 4/243 (1.65%) high-risk patients; 2 CRC (0.97%) 2 endometrial cancer (5.4%), and 1/120 unselected endometrial cancer patients (0.84%). Notably, in high-risk cases, BLM^Ash mutation carriers were diagnosed at a younger age (for CRC 47.5 ± 7.8 years; P = 0.32 ; endometrial cancer 49.5 ± 7.7 years; P = 0.36) compared with non-carriers.

Conclusions: Ashkenazi high risk CRC/endometrial cancer, and women with endometrial cancer have a higher rate of BLM^Ash heterozygous mutation compared with the general population. BLM^Ash heterozygous mutation carriers are diagnosed with CRC and endometrial cancer at a younger age compared with non-carriers. These observations should be validated and the possible clinical implications assessed.

Obstetric antiphospholipid syndrome (Obs-APS) is one of the most commonly identified causes of recurrent pregnancy loss and its accurate diagnosis is a requirement for optimal treatment. Some patients do not fulfill the revised Sapporo classification criteria, the original APS classification criteria, and are considered to be non-criteria Obs-APS. In these patients with non-criteria, there is controversy about their inclusion within the spectrum of APS and eventually their treatment as having Obs-APS. A subset of patients may also have clinical characteristics of Obs-APS even though lupus anticoagulant (LA), anticardiolipin antibodies, and anti-β2-glycoprotein I (aβ2GPI) antibodies are consistently negative. These patients are recognized as seronegative Obs-APS.

We reviewed evidence of non-criteria Obs-APS and discuss a case of a woman with a diagnosis of active systemic lupus erythematosus (SLE) and non-criteria Obs-APS with four consecutive pregnancy losses. After an accurate diagnosis the patient received prenatal counseling and benefited from the optimal treatment of Obs-APS that led to a successful pregnancy. The applicability of this successful experience about outcomes in women with non-criteria, or seronegative, Obs-APS is also evaluated.
