Four children of Turkish origin, three boys aged 12, 8 and 7 years, and a girl aged 5 years, presented with clinical symptoms of familial Mediterranean fever. They had the characteristic episodes of fever combined with abdominal pain, thoracic pain, general malaise or arthralgia. Familial Mediterranean fever is an autosomal recessive genetic disorder restricted to people originating from the Middle East. The causative gene (MEFV) and many missense mutations have been identified. The clinical syndrome is characterised by self-limiting febrile episodes accompanied by inflammation of the serous membranes, resulting in peritonitis, pleuritis or synovitis. In untreated patients systemic amyloidosis may develop, which manifests as renal insufficiency. The diagnosis is based on the characteristic medical history and is confirmed by DNA analysis. Meanwhile, treatment with colchicine can be started. This is effective in 90% of affected patients. Being aware of the prevalence of familial Mediterranean fever in immigrant populations can improve the quality of life and prevent long-term complications.

Familial Mediterranean fever (FMF) is a genetic disorder characterized by sporadic, acute attacks of fever and serosal inflammation. Typical manifestations are recurrent febrile episodes of acute instauration for brief duration (1 to 4 days) that is associated with severe pain due to serositis at one or more sites. Abdominal crisis occurs in 95% of the patients. Treatment with colchicine is highly effective as preventive treatment, but it is considered to be ineffective for the treatment of established acute attacks. As mentioned, untreated crisis resolves spontaneously in 1 to 4 days. Prolonged, nonresolving crisis of abdominal pain refractory to nonsteroidal anti-inflammatory drugs (NSAIDs) and opioids, with fever and elevation of acute phase reactants that resolves after the administration of colchicine, is a clinical presentation undescribed hitherto. The aim of this paper is to report a patient with this distinctively unusual clinical presentation of FMF.

Familial Mediterranean Fever (FMF) is an autosomal recessive genetic disorder characterised by recurrent and self-limited abdominal pain, synovitis and pleuritis. MEFV gene mutations are responsible from the disease and its protein product, pyrin or marenostrin, plays an essential role in the regulation of the inflammatory reactions. MEFV gene contains 10 exons and most of the mutations have been found on the last exon. Up to date, 152 mutations and polymorpisms have been reported inwhere V726A, M694V, M694I, M680I and E148Q are the most common mutations. In this study, MEFV allele frequencies of 136 individuals (60 from Pediatry, 76 from Internal Medicine) have been evaluated, and compared with each other. Asymptomatic individuals with FMF family history (4 from Pediatry, 6 from Internal Medicine) were excluded from the analysis. The prominent mutations indicated in the Pediatry group are V726A, M694V and M680I (G/C) and with the allele frequency of 0.06, 0.05 and 0.04 respectively while they were E148Q, M694V, M680I (G/C) in the Internal Medicine group with the allele frequency of 0.12, 0.08 and 0.04. The E148Q mutation is significantly overrepresented in the adult referrals (P = 0.02). Mutation on both alleles was observed in only 12% of cases. Overall mutation frequency was low, seen in 26.2% (66/252). However, when only diagnosed patients were analyzed it is 72.7% (16/22). It is also interesting that 63% of individuals are female that there may be sex influence on FMF phenotype.

Hereditary angioedema (HAE), a rare genetic disorder caused by a deficiency of the C1 esterase inhibitor, leads to an episodic, self-limiting increase in vascular permeability. Related symptoms commonly include recurrent, intractable abdominal pain, vomiting, and/or diarrhea. DX-88 (ecallantide), a 60-amino acid recombinant protein discovered through phage display technology, is a highly specific, potent inhibitor of human plasma kallikrein that has been used successfully in the treatment of patients experiencing acute HAE attacks. This case study involves a 65-year-old woman who presented with severe abdominal pain, cramping, and nausea. The study describes the use of a video obtained by capsule endoscopy for the direct imaging of bowel occlusion in a patient with HAE that resolved upon treatment with DX-88. After administration of DX-88, 80 mg intravenously, abdominal pain and nausea resolved within 30 min. Capsule endoscopy demonstrated a coincident resolution of the bowel wall edema, with a return to normal within approximately 1.5 h of DX-88 administration. This case study demonstrates that DX-88 can produce dramatic clinical benefits in a patient with an acute abdominal HAE attack, resolving both symptoms and pathologic signs. Furthermore, it illustrates the usefulness of videos obtained from capsule endoscopy in identifying the presence of bowel occlusion and demonstrating its subsequent rapid resolution upon administration of DX-88.

Gitelman syndrome (GS), also referred to as familial hypokalemia-hypomagnesemia, is characterized by hypokalemic metabolic alkalosis in combination with significant hypomagnesemia and low urinary calcium excretion. The prevalence is estimated at approximately 1:40,000 and accordingly, the prevalence of heterozygotes is approximately 1% in Caucasian populations, making it one of the most frequent inherited renal tubular disorders. In the majority of cases, symptoms do not appear before the age of six years and the disease is usually diagnosed during adolescence or adulthood. Transient periods of muscle weakness and tetany, sometimes accompanied by abdominal pain, vomiting and fever are often seen in GS patients. Paresthesias, especially in the face, frequently occur. Remarkably, some patients are completely asymptomatic except for the appearance at adult age of chondrocalcinosis that causes swelling, local heat, and tenderness over the affected joints. Blood pressure is lower than that in the general population. Sudden cardiac arrest has been reported occasionally. In general, growth is normal but can be delayed in those GS patients with severe hypokalemia and hypomagnesemia.GS is transmitted as an autosomal recessive trait. Mutations in the solute carrier family12, member 3 gene, SLC12A3, which encodes the thiazide-sensitive NaCl cotransporter (NCC), are found in the majority of GS patients. At present, more than 140 different NCC mutations throughout the whole protein have been identified. In a small minority of GS patients, mutations in the CLCNKB gene, encoding the chloride channel ClC-Kb have been identified.Diagnosis is based on the clinical symptoms and biochemical abnormalities (hypokalemia, metabolic alkalosis, hypomagnesemia and hypocalciuria). Bartter syndrome (especially type III) is the most important genetic disorder to consider in the differential diagnosis of GS. Genetic counseling is important. Antenatal diagnosis for GS is technically feasible but not advised because of the good prognosis in the majority of patients.Most asymptomatic patients with GS remain untreated and undergo ambulatory monitoring, once a year, generally by nephrologists. Lifelong supplementation of magnesium (magnesium-oxide and magnesium-sulfate) is recommended. Cardiac work-up should be offered to screen for risk factors of cardiac arrhythmias. All GS patients are encouraged to maintain a high-sodium and high potassium diet. In general, the long-term prognosis of GS is excellent.

Tangier disease is a rare genetic disorder of lipid metabolism, characterized by severe deficiency of plasma high-density lipoprotein cholesterol, low-plasma total cholesterol, and accumulation of cholesteryl ester in macrophages. Abdominal manifestation of Tangier disease is extremely rare, being reported only once in the English literature. We describe a 55-year-old patient with this condition, who underwent splenectomy 37 years before, because of splenomegaly with thrombocytopenia, and subsequently presented with abdominal pain and pancreatic mass, simulating a pancreatic tumor. The preoperative diagnosis of endocrine or solid-cystic neoplasm was made, and the tumor was successfully resected with distal pancreatectomy. Histological examination showed that the mass was composed of histiocytic cells containing lipids; some aggregates of giant polynucleated histiocytes with intracytoplasmic cholesterol crystals. To our knowledge, this is the first report of pancreatic manifestation of Tangier disease. As suggested earlier, splenectomy in these patients seems to predispose to deposition of lipids and infiltration of the abdomen by inflammatory cells.

Anderson-Fabry disease (AFD) is an X-linked recessive lysosomal disease caused by alpha-galactosidase A (alpha-gal) deficiency, causing progressive glycosphingolipid storage in various organ systems. Headache is a frequent symptom. Cerebral magnetic resonance imaging (MRI) often shows multiple white matter lesions (WML), like those seen in patients affected by migraine, in particular with aura (MA). To our knowledge, there are no reports about the prevalence of AFD in patients with MA. The objective of the study was to determine AFD prevalence, as assessed by alpha-gal activity and genetic tests, in MA patients. We evaluated 73 consecutive patients followed by the Headache Centre of our Department with a diagnosis of MA. They were screened for migraine characteristics and cerebrovascular risk factors. Gaseous contrast transcranial Doppler was used to diagnose right-to-left shunt and MRI to detect WML. All patients underwent blood test to evaluate peripheral alpha-gal activity and to identify alpha-gal gene mutations. Of 73 consecutive screened subjects (59 females, 14 males; mean age 38.3 +/- 11.8 years), the known GLA pathologic mutation p.[Asp313Tyr] was found in a 38-year-old woman, with a history of MA, deep venous thrombosis and abdominal pain. Cerebral MRI showed small WML. This is the first study reporting AFD prevalence in a cohort of MA patients. We found a relatively high prevalence (about 1.37%) among the examined patients, even if this finding needs to be confirmed in a larger sample. Despite this high prevalence, it seems not necessary to screen systematically all MA patients for AFD, but since it is a treatable genetic disorder, it is worthwhile to consider it for the subgroup of patients presenting WML and other typical AFD symptoms.

Hereditary angioedema (HAE) is a relatively rare genetic disorder that is most commonly caused by a deficiency of C1 inhibitor. It is estimated that HAE affects at least one in 10,000 to one in 50,000 of the worldwide population, with relapsing swelling of the skin and abdominal pain attacks being the most common clinical symptoms. Most seriously, laryngeal edema associated with HAE may lead to death. Replacement therapy with intravenous pasteurized C1 inhibitor concentrate is the recommended treatment for acute attacks of HAE, resulting in a rapid resolution of symptoms. Pasteurized C1 inhibitor concentrates can also be used for prophylaxis of HAE, and are currently also being assessed for home therapy in this setting. Future advances may improve disease burden and mortality associated with HAE.

Hereditary angioedema (HAE) is a relatively rare genetic disorder caused by a deficiency of C1 esterase inhibitor (C1-INH). Common clinical presentations are abdominal pain and localized edema of the skin, with laryngeal edema being potentially life-threatening. Replacement therapy with C1-INH concentrate is recommended for treatment of acute HAE attacks and results in rapid resolution of symptoms. C1-INH concentrate can also be used for prophylaxis of HAE and is recommended in cases where standard prophylactic agents are ineffective or not tolerated. This case study describes the use of C1-INH concentrate as a home therapy for on-demand and prophylactic self-administration in a patient with HAE. This treatment approach was well tolerated and effective, leading to a dramatic improvement in symptoms and improved quality of life.

Hereditary angioedema is a rare genetic disorder resulting from an inherited deficiency or dysfunction of the C1 inhibitor. It is characterized by recurrent, circumscribed, and self-limiting episodes of cutaneous and mucous membrane swelling involving different organs. Hereditary angioedema may present with diverse clinical pictures, even within families with the same mutation. We present a first reported case of type 1 hereditary angioedema in a young woman presenting as recurrent abdominal pain associated with ascites without any other clinical features of hereditary angioedema, with initial presentation in puerperium. The recognition or awareness of hereditary angioedema as a cause of acute and/or recurrent abdominal pain associated with ascites is important, and may avoid unnecessary invasive procedures and facilitate appropriate treatment.
