The concept of autoimmune pancreatitis has recently been established, and ultrasonographic findings we obtained from five cases consistent with autoimmune pancreatitis are reported here. Case 1, a 77-year-old man, was admitted complaining of loss of body weight. Serum hepatobiliary enzymes and γ-globulin levels were elevated, and antinuclear antibody was positive, Abdominal ultrasonography showed dilatation of the intrahepatic bile duct, wall thickening of the common bile duct and hypoechoic swelling of the pancreatic head and body. ERCP revealed multiple stenosis of the intra-and extra-hepatic bile ducts, and diffuse irregular narrowing of the main pancreatic duct. The patient complained of thirst, and the minor salivary gland was examined histologically. Our diagnosis was Sjögren syndrome accompanied by sclerosing cholangitis and a pancreatic lesion. Obstructive jaundice also developed, and PTCD was therefore performed. Both the pancreatic swelling and multiple stenosis of the bile duct improved after steroids were administered. Case 2, a 71-year-old man, was admitted with jaundice. Abdominal ultrasonography showed hypoechoic swelling of the pancreas. ERCP showed stenosis of the common bile duct in the pancreatic head region and diffuse irregular narrowing of the main pancreatic duct. Histological examination of the minor salivary gland suggested Sjögren syndrome. Steroids were therefore administered because the presence of both hyper-γ-globulinemia and positive antinuclear antibody suggested involvement of the autoimmune mechanism. Steroid therapy improved the jaundice as well as the findings from the cholangiograms and pancreatograms. We also encountered three similar cases, all consistent with the concept of autoimmune pancreatitis. The ultrasonographic findings of the pancreatic lesion (1) showed them as homogeneous and markedly hypoechoic areas and, (2) visualized the main pancreatic duct in the lesion, which facilitated a differential diagnosis of the

A case was considered in detail of a patient with pulmonary edema of immunnocomplex nature in aerogenic intoxication by nickel tetracarbonyl. It was shown that acute aerogenic intoxication nickel carbonyl by led to unfolded toxic autoimmune syndrome. In this case autoimmune immunecomplex pulmonary lesion (AIPL) menifested by progressing pulmonary edema with expressed parenchymatous respiratory insufficiency played a leading role. Lesion of endothelium of pulmonary capillaries by immune complexes has the most significant in pathogenesis of pulmonary edema. The fact that edema appears due to AIPL, is confirmed by high efficiency of glucocorticoid therapy. Use of glucorticoids serves as a diagnostic test which provides an effective roentgenologic diagnosis of AIPL and differential diagnosis of any other pathological processes in the lungs

Autoimmune Syndrome Induced by Adjuvant (ASIA) is a definition aimed to describe the common etiological process at the root of five clinical entities sharing similar symptomatology: macrophagic myofasciitis syndrome (MMF), Gulf War Syndrome (GWS), sick building syndrome (SBS), siliconosis, and post vaccination autoimmune phenomena. ASIA illustrates the role of environmental immune stimulating agents, or adjuvants, in the instigation of complex autoimmune reactions among individuals bearing a genetic preponderance for autoimmunity. The value of ASIA lies first in the acknowledgment it provides for patients suffering from these as yet ill-defined medical conditions. Equally important is the spotlight it sheds for further research of these poorly understood conditions sharing a common pathogenesis. In this article we elaborate on the significance of ASIA, review the current evidence in support of the syndrome, and address recent reservations raised regarding its validity.

Vialettes, Bernard; Dubois-Leonardon, Noémie

2013-01-01

Type 2 autoimmune polyendocrine syndromes (APS-2) are the most frequent disorders associating several organ-specific autoimmune diseases. Their high prevalence is due to the fact that the main manifestations of APS-2, such as thyroidal autoimmunity, type 1 diabetes, autoimmune gastric atrophy and vitiligo, are common diseases. APS-2 represents a clinical model that can serve to help unravel the mechanisms underlying autoimmunity. Diagnosis of APS-2 is a challenge for the clinician, especially in poorly symptomatic forms, and may require systematic screening based on measurement of autoantibodies and functional markers.

Full Text Available The combination of at least three autoimmune diseases in the same patient has defined as multiple autoimmune syndrome (MAS. Abnormalities of T cell-mediated immunity and humoral immunity have been described previously in the literature. Aims of work were to investigate the 22 years old patient with lupus erythematosus for three years and autoimune thyroiditis for one year, regardind other possible autoimmune conditions and to establish a treatment to control the diseases. The clinical exam revealed some circular hairless patches on the beard appeared about three months ago and white depigmented disseminated areas started one month ago and the laboratory investigations were performed. The modified laboratory findings were total IgE 530 UI/mL, Anti-SSA (anti-RO antibodies> 200 IU/mL, SSB negative, Antinuclear antibodies (ANA positive and fine speckled, Lupus anticoagulant testing positive, Anti-thyroid peroxidase antibodies 951 UI/ml, TSH 4,7 µUI/mL. The diagnosis of multiple autoimmune syndrome(MAS type 3 including Lupus erythematosus, autoimune Thyroiditis, Alopecia Areata and Vitiligo was established. Endocrine autoimmunities are associated with autoantibodies that react to specific antigens, whereas patients with collagen diseases synthesize immunoglobulins that recognize nonorgan-specific cellular targets, such as nucleoproteins and nucleic acids. Cellular autoimmunity is important in the pathogenesis MAS. The existence of one autoimmune disorder helps lead to the discovery of other autoimmune conditions.

Smith-Magenis syndrome (SMS) is a sporadic congenital disorder involving multiple organ systems caused by chromosome 17p11.2 deletions. Smith-Magenis syndrome features craniofacial and skeletal anomalies, cognitive impairment, and neurobehavioral abnormalities. In addition, some SMS patients may exhibit hypogammaglobulinemia. We report the first case of SMS-associated autoimmunity in a woman who presented with adult onset of multiple autoimmune disorders, including systemic lupus erythematosus, antiphospholipid antibody syndrome, and autoimmune hepatitis. Molecular analysis using single-nucleotide polymorphism array confirmed a de novo 3.8-Mb deletion (breakpoints, chr17: 16,660,721-20,417,975), resulting in haploinsufficiency for TACI (transmembrane activator and CAML interactor). Our data are consistent with potential loss of function for the BAFF (B cell-activating factor) receptor TACI as a contributing factor to human autoimmune phenomena.

Cocaine/levamisole-associated autoimmune syndrome: a disease of neutrophil-mediated autoimmunity.

Science.gov (United States)

Cascio, Michael J; Jen, Kuang-Yu

2018-01-01

Levamisole was previously used for its immunomodulatory properties to treat rheumatoid arthritis and some cancers. However, because of serious side-effects, it was taken off the market in the United States. Recently, levamisole has reemerged as a popular cocaine adulterant. Some individuals who consume levamisole-adulterated cocaine can develop a life-threatening autoimmune syndrome. In this review, the medical consequences of levamisole exposure and postulated mechanisms by which levamisole induces these adverse effects are discussed. Although agranulocytosis and cutaneous vasculitis are the major findings in patients who develop cocaine/levamisole-associated autoimmune syndrome (CLAAS), more recent experience indicates that other organ systems can be involved as well. Current studies point to neutrophil activation and neutrophil extracellular trap formation with subsequent antineutrophil cytoplasmic antibody-mediated tissue injury as a possible mechanism of CLAAS. In the past decade, the detrimental effects of levamisole have reemerged because of its popularity as a cocaine adulterant. Although infrequent, some individuals develop a systemic autoimmune syndrome characterized by immune-mediated agranulocytosis and antineutrophil cytoplasmic antibody-mediated vasculitis. Mechanistically, neutrophil antigens appear to be a major player in inducing CLAAS. Prompt cessation of levamisole exposure is key to treatment, although relapses are frequent because of the addictive effects of cocaine and the high prevalence of levamisole within the cocaine supply.

Polyglandular autoimmune syndromes are rare diseases based on autoimmune mechanisms in which endocrine and non-endocrine disorders coexist. In type 1 the characteristic manifestations are chronic mucocutaneous candidiasis, hypoparathyroidism and adrenal insufficiency. A case is presented of a patient with typical clinical sequence, along with other changes, and in whom a mutation in homozygosis, C322fsX372, was detected after performing a molecular analysis of autoimmunity regulator gene (AIRE). Inheritance is autosomal recessive, associated with mutations in the AIRE gene, which encodes a protein involved in autoimmunity and immunodeficiency. For diagnosis, At least two of the three major clinical manifestations are required for a diagnosis. However, only one of them is necessary in the study of relatives of affected patients. These syndromes must be diagnosed early, given their high morbidity and mortality. Every manifestation needs to be treated, in order to maintain the quality of life.

Autoimmune polyglandular syndromes (APS) comprise a wide clinical spectrum of autoimmune disorders. APS is divided into Type I, Type II, Type I and Type IV depending upon the pattern of disease combination. Ghronic diarrhoea is one of the many manifestations of APS and many aetiological factors have been suggested for it. Apart from the established aetiological factors, intestinal lymphangiectasia may be responsible for chronic diarrhea in some cases.Intestinal lymphangiectasia has been reported in Type I APS. We report a case of Type III APS with hypocalcaemia and hypothyroidism who had chronic diarrhea of long duration and was finally diagnosed to have intestinal lymphangiectasia.

Coxiella burnetii as a possible cause of autoimmune liver disease: a case report

Kaech Chloe

2009-08-01

Full Text Available Abstract Introduction Q fever is a zoonotic infection that may cause severe hepatitis. Q-fever hepatitis has not yet been associated with autoimmune hepatitis and/or primary biliary cirrhosis. Case presentation We describe a 39-year-old man of Sri Lankan origin with chronic Q-fever hepatitis who developed autoantibodies compatible with autoimmune hepatitis/primary biliary cirrhosis overlap syndrome. Ursodeoxycholic acid in addition to antibiotic therapy markedly improved hepatic enzyme levels suggesting that autoimmunity, potentially triggered by the underlying infection, was involved in the pathogenesis of liver damage. Conclusion We suggest that Coxiella burnetii might trigger autoimmune liver disease. Patients with Q-fever hepatitis who respond poorly to antibiotics should be investigated for serological evidence of autoimmune hepatitis, primary biliary cirrhosis or overlap syndrome, as these patients could benefit from adjunctive therapy with ursodeoxycholic acid. Conversely, C. burnetii serology might be necessary in patients with autoimmune liver disease in order to exclude underlying Coxiella infection.

Multiple autoimmune syndrome (MAS), an extreme phenotype of autoimmune disorders, is a very well suited trait to tackle genomic variants of these conditions. Whole exome sequencing (WES) is a widely used strategy for detection of protein coding and splicing variants associated with inherited diseases. The DNA of eight patients affected by MAS [all of whom presenting with Sjögren's syndrome (SS)], four patients affected by SS alone and 38 unaffected individuals, were subject to WES. Filters to identify novel and rare functional (pathogenic-deleterious) homozygous and/or compound heterozygous variants in these patients and controls were applied. Bioinformatics tools such as the Human gene connectome as well as pathway and network analysis were applied to test overrepresentation of genes harbouring these variants in critical pathways and networks involved in autoimmunity. Eleven novel and rare functional variants were identified in cases but not in controls, harboured in: MACF1, KIAA0754, DUSP12, ICA1, CELA1, LRP1/STAT6, GRIN3B, ANKLE1, TMEM161A, and FKRP. These were subsequently subject to network analysis and their functional relatedness to genes already associated with autoimmunity was evaluated. Notably, the LRP1/STAT6 novel mutation was homozygous in one MAS affected patient and heterozygous in another. LRP1/STAT6 disclosed the strongest plausibility for autoimmunity. LRP1/STAT6 are involved in extracellular and intracellular anti-inflammatory pathways that play key roles in maintaining the homeostasis of the immune system. Further; networks, pathways, and interaction analyses showed that LRP1 is functionally related to the HLA-B and IL10 genes and it has a substantial impact within immunological pathways and/or reaction to bacterial and other foreign proteins (phagocytosis, regulation of phospholipase A2 activity, negative regulation of apoptosis and response to lipopolysaccharides). Further, ICA1 and STAT6 were also closely related to AIRE and IRF5, two very

Autoimmune polyglandular syndrome is a primary autoimmune disorder affecting two or more peripheral endocrine glands and responsible for their incompetence. It is frequently combined with various organ-specific non-endocrine diseases. Patients with this pathology need life-long replacement therapy and dynamic observation by endocrinologists and other specialists to monitor the effectiveness of the treatment and detect new components of the disease. We report a variant of type 1 autoimmune polyglandular syndrome. Special emphasis is laid on the importance of succession of actions of endocrinologists and specialists in related medical disciplines dealing with children and adult patients.

Neuromyelitis optica (NMO) associated with nephrotic syndrome and autoimmune-related pancytopenia has not been reported previously. We report herein a young woman who initially presented with bilateral blurring of vision and numbness in her hands. MRI disclosed multiple white matter lesions and a long cervical spinal cord lesion extending to the medulla oblongata. Serum aquaporin-4 antibody was positive and the patient was diagnosed with NMO. While in the hospital, she presented with hypoproteinemia and heavy proteinuria, meeting the diagnostic criteria of nephrotic syndrome. After high-dose methylprednisolone treatment, her vision improved significantly and urine protein quantity decreased. However, the patient subsequently developed severe pancytopenia with a positive Coombs' test. Thrombocytopenia finally led to uncontrollable gastrointestinal bleeding as the direct cause of the patient's death. This case illustrates the extremely rare condition of concurrence of NMO, nephrotic syndrome, and autoimmune pancytopenia in one patient, which suggests the involvement of organs beyond the central nervous system in NMO spectrum disorders.

Multiple endocrinopathies (growth hormone deficiency, autoimmune hypothyroidism and diabetes mellitus in Kearns-Sayre syndrome

Full Text Available Kearns-Sayre syndrome is characterized by onset before 20 years, chronic progressive external opthalmoplegia, pigmentary retinal degeneration, and ataxia (and/or hearth block, and/or high protein content in the cerebrospinal fluid in the presence of mtDNA rearrangements. Multiple endocrine dysfunction associated with this syndrome was rarely reported. In this paper, the Authors report on a female patient with Kearns-Sayre syndrome with large heteroplasmic mtDNA deletion, absence of cytochrome c oxidase in many muscle fibers, partial GH deficiency, hypothyroidism and subsequently insulin dependent diabetes mellitus (IDDM. Anti-thyroid peroxidase and antithyreoglobulin antibodies were present in high titer in serum while anti-islet cell antibodies were absent. The patient developed thyroiditis with Hashimoto encephalopathy. The presence of GH deficiency, autoimmune thyroiditis with hypothyroidism and IDDM distinguishes this case from others and confirms the association of Kearns-Sayre syndrome with multiple endocrine dysfunction. Hashimoto encephalopathy and anti-thyroideal antibodies suggest that in this patient, predisposed by a genetic factor (a mitochondrial deletion anti-thyroideal antibodies may have contributed to the hypothyroidism and, by interfering with cerebral mitochondrial function, may have caused the encephalopathy. GH deficiency and IDDM can be attributed to oxidative phosphorylation deficiency but the autoimmunity may also have played a role in the production of glandular insufficiencies. It seems important to search for endocrine autoimmunity in every case of KSS.

Autoimmune Polyendocrine Syndrome 3 Onset with Severe Ketoacidosis in a 74-Year-Old Woman

Full Text Available Type 1 diabetes mellitus (T1D, autoimmune thyroid disease, and autoimmune gastritis often occur together forming the so-called autoimmune polyendocrine syndrome type 3 (APS3. We here report a clinical case of a 74-year-old woman who presented for the first time with severe hyperglycemia and ketoacidosis diagnosed as T1D. Further clinical investigations revealed concomitant severe hypothyroidism with autoimmune thyroid disease and severe cobalamin deficiency due to chronic atrophic gastritis. The diagnosis of type 1 diabetes mellitus was confirmed by the detection of autoantibodies against glutamic acid decarboxylase 65, islet cell antibodies, and anti-insulin autoantibodies. Anti-thyroperoxidase, anti-thyroglobulin, and anti-gastric parietal cell antibodies were also clearly positive. The case emphasized that new onset diabetic ketoacidosis, hypothyroidism, and cobalamin deficiency may simultaneously occur, and one disease can mask the features of the other, thereby making diagnosis difficult. It is noteworthy that an APS3 acute episode occurred in an asymptomatic elder woman for any autoimmune diseases.

Type 1 diabetes and polyglandular autoimmune syndrome: A review

Science.gov (United States)

Hansen, Martin P; Matheis, Nina; Kahaly, George J

2015-01-01

Type 1 diabetes (T1D) is an autoimmune disorder caused by inflammatory destruction of the pancreatic tissue. The etiopathogenesis and characteristics of the pathologic process of pancreatic destruction are well described. In addition, the putative susceptibility genes for T1D as a monoglandular disease and the relation to polyglandular autoimmune syndrome (PAS) have also been well explored. The incidence of T1D has steadily increased in most parts of the world, especially in industrialized nations. T1D is frequently associated with autoimmune endocrine and non-endocrine diseases and patients with T1D are at a higher risk for developing several glandular autoimmune diseases. Familial clustering is observed, which suggests that there is a genetic predisposition. Various hypotheses pertaining to viral- and bacterial-induced pancreatic autoimmunity have been proposed, however a definitive delineation of the autoimmune pathomechanism is still lacking. In patients with PAS, pancreatic and endocrine autoantigens either colocalize on one antigen-presenting cell or are expressed on two/various target cells sharing a common amino acid, which facilitates binding to and activation of T cells. The most prevalent PAS phenotype is the adult type 3 variant or PAS type III, which encompasses T1D and autoimmune thyroid disease. This review discusses the findings of recent studies showing noticeable differences in the genetic background and clinical phenotype of T1D either as an isolated autoimmune endocrinopathy or within the scope of polyglandular autoimmune syndrome.

Full Text Available Evans´ syndrome is the coexistence of autoimmune thrombocytopenia with autoimmune hemolytic anemia. It is rarely found during the course of a pregnancy. This makes treatment options more difficult, since some therapeutic drugs are teratogenic. The effects of Evans´ syndrome in the fetus and newborn are unknown given the low number of reported cases. We report the case of a patient with preconceptional diagnosis of Evans´ syndrome, who develops a hemolytic crisis during the course of a pregnancy, and diagnosis of intrauterine growth restriction (IUGR, treated at Clínica Ginecotocológica “A” at the Pereira Rossell Hospital Center, in Montevideo, Uruguay. Treatment options and evolution are analyzed, as well as previous reports.

To evaluate the frequency of non-autoimmune subclinical and overt hypothyroidism in children with idiopathic steroid-resistant nephrotic syndrome (SRNS). This cross-sectional study recruited 30 children (age 1-18 y) with idiopathic SRNS; and 30 healthy controls. Serum T3, T4 and TSH were performed in cases as well as controls. Anti-thyroid peroxidase and anti-thyroglobulin antibody tests were performed in all cases. Non-autoimmune subclinical or overt hypothyroidism was detected in 10 out of 30 children with idiopathic SRNS; 2 had overt hypothyroidism, while 8 patients had subclinical hypothyroidism. Children with SRNS had a mean (SD) TSH value 4.55 (4.64) mIU/L that was higher as compared to controls (1.88 (1.04) mIU/L) (Phypothyroidism (2 cases) and grade III subclinical hypothyroidism (1 case) were subsequently started on levothyroxine therapy. The prevalence of subclinical and overt hypothyroidism seems to be high in idiopathic SRNS, with almost one-third of children having overt or subclinical non-autoimmune hypothyroidism.

Autoimmune Syndrome Induced by Adjuvants (ASIA after Silicone Breast Augmentation Surgery

Directory of Open Access Journals (Sweden)

Daniel Nunes e Silva, MD

2017-09-01

Full Text Available Summary:. Generally, the main complications of silicone implantation are local symptoms. However, some patients develop late-onset systemic symptoms often associated with a rare form of hyperactive immune response, as part of a syndrome known as autoimmune syndrome induced by adjuvants (ASIA. Reported cases of ASIA have shown resolution with explantation, but not with immunomodulatory therapy. In this report, we described a case of a previously healthy 23-year-old woman, who has undergone silicone breast implant augmentation, for aesthetic reasons, and developed localized cutaneous impairment 3 years postsurgery. She received a diagnosis of ASIA with a new presentation: Lupus-like manifestation through localized cutaneous impairment. This patient’s symptoms were managed without the need for surgical intervention, which has not been previously reported, because the patient did not want an explantation for aesthetic reasons. The patient was started on hydroxychloroquine, 400 mg per day, and remains asymptomatic after 2 years of treatment. The exact predisposition to ASIA is still unknown. Without implant explantation and with immunomodulatory treatment, this patient’s condition substantially improved. Based on our current understanding of this disease, it might not be prudent to indicate breast augmentation with silicone implants in patients with documented autoimmune reaction to an adjuvant, an established autoimmune condition, or genetic predisposition. However, if a patient does develop silicone-induced ASIA, explantation is no longer the only successfully reported option, as these symptoms can be managed with immune suppression.

2015-04-01

Autoimmune Polyglandular syndrome (APS) are rare condition characterised by presence of immune dysfunction of two or more endocrine glands and other non-endocrine organs. APS is divided into 2 major subtypes based on age of presentation, pattern of disease combinations and mode of inheritance. APS 1(juvenile) usually manifest in early adolescence or in infancy. It is characterised by multiple endocrinal deficiency with mucocutaneous candidiasis and ectodermal dystrophy. Of the endocrine diseases, hypoparathyroidism form an important component followed by Addison's disease, type 1A diabetes, hypogonadism and thyroid disease. On the other hand APS II usually manifest in 3rd or 4th decade of life with female preponderance. Endocrine diseases commonly include autoimmune thyroid disease (graves or autoimmune thyroiditis), type 1A diabetes, and Addison's disease. Hypoparathyroidism is of rare occurrence and there is no mucocutaneous candidiasis. We report here a case of APS type II in a 29-year-old male who initially presented with hypothyroidism, which was soon followed by Addison's disease. The involvement of thyroid gland preceding the involvement of adrenal is of rare occurrence. The patient also had celiac disease which makes the combination further uncommon.

Full Text Available Introduction. Erythema elevatum et diutinum (EED is classified as a variant of leukocytoclastic vasculitis. The etiology of this disease is unknown. Erythema elevatum et diutinum may coexist with several systemic disorders including hematologic and rheumatologic diseases as well as type 1 diabetes, thyroid diseases and other endocrinopathies. Autoimmune polyglandular syndromes (APS are rarely diagnosed conditions characterized by the coexistence of at least two autoimmune endocrinopathies and non-endocrine autoimmunopathies. Objective. Presentation of a patient with EED coexisting with APS type 3. Case report. A 23-year-old male patient was admitted to our department due to nodular lesions lasting for 5 months, located on the extremities, which were diagnosed clinically and confirmed histopathologically as EED. In spite of skin lesions the patient suffered from diabetes mellitus type 1, hyperthyroidism, celiac disease, myopathy and idiopathic urticaria – abnormalities characteristic for APS type 3. Substantial clinical improvement was observed after systemic administration of dapsone and, due to upper respiratory tract infection, a few weeks of antibiotic therapy. Conclusions . We present this case due to the rarity of EED, especially coexisting with APS, and the good effect of therapy with dapsone and oral antibiotics.

Possible Association of Multicentric Castleman's Disease with Autoimmune Lymphoproliferative Syndrome

2018-04-01

Full Text Available Multicentric Castleman's disease (MCD is lymphoproliferative disorder characterized by systemic inflammatory symptoms such as fever and weight loss. Human herpes virus-8 (HHV-8 is thought to be a causable pathogen in all HIV-positive and some HIV-negative MCD patients. Furthermore, the term idiopathic MCD (iMCD was recently proposed to represent a group of HIV-negative and HHV-8-negative patients with unknown etiologies. Although the international diagnostic criteria for iMCD require exclusion of infection-related disorders, autoimmune/autoinflammatory diseases and malignant/lymphoproliferative disorders to make an iMCD diagnosis, the relationships and differences between these disorders and MCD have not yet been clarified. We recently reported the first case of MCD with autoimmune lymphoproliferative syndrome (ALPS. Although ALPS was included in the iMCD exclusion criteria as an autoimmune/autoinflammatory disease according to the international diagnostic criteria, there is a lack of evidence on the association between MCD and ALPS. In this study, we review the recent understanding of MCD and discuss the possible association between MCD with ALPS.

A strange case of Evans syndrome

Full Text Available Evans syndrome is a rare autoimmune disease presenting hemolytic anemia, thrombocytopenia and/or neutropenia. It may be associated with other autoimmune or lymphoproliferative diseases. It can have an extremely serious disease course and, in rare cases, this can even be life-threatening. First-line treatment consists of steroids and/or immunoglobulin. Further therapy with rituximab, vincristine, cyclophosphamide and other immunosuppressive drugs can be considered in unresponsive patients. We report a case of Evans syndrome in a 54-year old woman admitted to the Emergency Department (ED for asthenia. Etiopathogenic, clinical, therapeutic and evolutive aspects are discussed. In contrast to many cases described in the literature, our patient had a satisfactory response to corticoids. We also discuss how to make a specific diagnosis, even in a suburban ED with limited resources, in order to admit patients to the appropriate hospital department and allow the correct therapy to be started as early as possible.

The autoimmune hepatitis (AIH)-primary biliary cirrhosis (PBC) overlap syndrome is characterized for clinical, biochemical, immunological, and histological features overlapping those of AIH and PBC, whose pathogenesis and more appropriate treatment are unknown at present. We describe two new patients of this entity, which made debut with cholestasic acute hepatitis accompanied of hypergammaglobulinemia. In the first patient was demonstrated the presence of AMA, ASMA, and anti-LKM1 autoantibodies; and ANA in the second one. The histological findings showed changes suggestive of AIH and PBC. After the start of immunosuppressive treatment, associated to ursodeoxycholic acid in one patient, a successful outcome was observed.

Autoimmune progesterone dermatitis is an uncommon disease presenting with cyclical skin eruptions corresponding with the menstrual cycle luteal phase. Because symptoms are precipitated by rising progesterone levels, treatment relies on hormone suppression. A 22-year-old nulligravid woman presented with symptoms mistaken for Stevens-Johnson syndrome. A cyclic recurrence of her symptoms was noted, and the diagnosis of autoimmune progesterone dermatitis was made by an intradermal progesterone challenge. After 48 months, she remained refractory to medical management and definitive surgical treatment with bilateral oophorectomy was performed. Autoimmune progesterone dermatitis is a challenging diagnosis owing to its rarity and variety of clinical presentations. Treatment centers on suppression of endogenous progesterone and avoidance of exogenous triggers. When these modalities fail, surgical management must be undertaken.

Liver abnormalities that normalize during infancy as well an enteropathy are reported in Shwachman-Diamond syndrome (SDS). The pathogenesis of both conditions is unknown. We report two SDS cases with autoimmune-like (antismooth muscle and/or antinuclear antibody positivity) liver disease and antigliadin antibody positive inflammatory enteropathy. Hypertransaminasemia did not resolve after immunosuppressive therapy and/or a gluten-free diet. These transient autoimmune phenomena and gut-liver axis perturbations may have played a role in transient SDS hepatopathy and enteropathy. Our report may stimulate other studies to define the relationship between the SDS genetic defect and intestinal permeability as the pathogenic mechanism underlying SDS related liver and intestinal inflammation.

Full Text Available The relationship between Sjögren’s syndrome (SS and neuromyelitis optica spectrum disorder (NMOSD is not completely understood. We report two patients with both conditions and review 47 other previously reported cases meeting currently accepted diagnostic criteria, from 17 articles extracted from PubMed. Out of 44 patients whose gender was informed, 42 were females. Mean age at onset of neurological manifestation was 36.2 years (10-74. Serum anti-AQP4-IgG was positive in 32 patients, borderline in 1, and negative in 4. Our Case 1 was seronegative for AQP4-IgG and had no non-organ-specific autoantibodies other than anti-SSB antibodies. Our Case 2 had serum anti-AQP4, anti-SSA/SSB, anti-thyreoglobulin and anti-acethylcholine-receptor antibodies, as well as clinical hypothyreoidism, but no evidence of myasthenia gravis. Our Cases and others, as previously reported in literature, with similar heterogeneous autoimmune response to aquaporin-4, suggest that SS and NMO co-exist in a common autoimmune milieu which is not dependent on aquaporin-4 autoimmunity.

Full Text Available Multiple sclerosis (MS, the most frequent demyelinating disease in adults, is thought to be an autoimmune disease. Symptoms and signs observed in MS reflect lesions present mainly in the white matter of the central nervous system (CNS. The diagnosis remains difficult, at least concerning presenting symptoms, because of their low specificity. Diagnosis criteria are usually based on dissemination of signs in time and space, evoked potentials, findings of magnetic resonance imaging, results of cerebrospinal fluid examination, and the exclusion of other diagnosis possibly explaining the clinical signs. However, no clinical and paraclinical investigation can distinguish with certainity MS from other conditions such as autoimmune or inflammatory diseases predominantly affecting the central nervous system. These other disorders include systemic lupus erythematosus, antiphospholipid syndrome, Behcet disease, Sjogren syndrome, sarcoidosis and vasculitides. We present four clinical cases showing the difficulty in reaching a proper diagnosis...

2017-09-01

Auto-immune polyendocrine syndrome type 1 (APS1) also called Auto-immune Polyendocrinopathy Candidiasis Ectodermal Dystrophy (APECED) is a rare monogenic childhood-onset auto-immune disease. This autosomal recessive disorder is caused by mutations in the auto-immune regulator (AIRE) gene, and leads to autoimmunity targeting peripheral tissues. There is a wide variability in clinical phenotypes in patients with APSI, with auto-immune endocrine and non-endocrine disorders, and chronic mucocutaneous candidiasis. These patients suffer from oral diseases such as dental enamel hypoplasia and candidiasis. Both are frequently described, and in recent series, enamel hypoplasia and candidiasis are even the most frequent components of APS1 together with hypoparathyroidism. Both often occur during childhood (before 5 years old for canrdidiasis, and before 15 years old for enamel hypoplasia). Oral candidiasis is recurrent all life long, could become resistant to azole antifungal after years of treatment, and be carcinogenic, leading to severe oral squamous cell carcinoma. Oral components of APS1 should be diagnosed and rigorously treated. Dental enamel hypoplasia and/or recurrent oral candidiasis in association with auto-immune diseases in a young child should prompt APS1 diagnosis. Copyright © 2017 Elsevier Masson SAS.

Autoimmune neurological syndrome is a group of disorders caused by cancer affecting nervous system by different immunological mechanisms. In this study, we aim to study the clinical symptoms, cerebrospinal fluid (CSF) findings, autoantibody tests, computed tomography (CT), magnetic resonance imaging (MRI) signs and treatment outcome of patients with autoimmune syndromes. In this study, 7 patients (4 male, 3 female) diagnosed with autoimmune neurological syndrome were retrospectively examined. Five of patients were diagnosed with limbic encephalitis, two of them were paraneoplastic cerebellar degeneration. Confusion and seizure were the most seen symptoms. Two patients had psychiatric disturbances (28,5%) followed by seizure. Headache was seen in 2 patients (% 28,5), disartria in 1 patient (% 14,2), and gait disorder in 2 patients (28,5%). The duration of symptoms was 46 (3-150) days on average. CSF abnormalities were detected in 2 patients. CT and MRI of the brain was available in all patients. Five patients had involvement of mesiotemporal region, two patients had diffuse cerebellar atrophy. One of patients had anti-GABAR B1 positivity. Tumors were detected in 2 patients while investigation for paraneoplasia screening. Remission is only possible with the detection and treatment of the malignancy. Early diagnosis and treatment are of paramount importance. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Primary Sjögren′s syndrome without ocular involvement: A rare case report

Full Text Available Sjögren′s Syndrome (SS is a chronic systemic autoimmune disorder, characterized by the lymphocytic infiltration of lacrimal and salivary glands, giving rise to dry eyes (keratoconjunctivitis sicca and dry mouth (xerostomia. Primary Sjögren′s Syndrome commonly presents only with sicca manifestations; whereas, secondary Sjögren′s syndrome occurs in connection with other autoimmune rheumatic diseases. Primary Sjögren′s syndrome without ocular manifestation is rarely reported in the literature. Here we report a case of a 45-year-old female, who presented to us with complaints of dryness of mouth and dysphagia, without any ocular and systemic manifestations. On further evaluation she was diagnosed as a case of Primary Sjögren′s syndrome. With this case report, we intend to emphasize the importance of an early diagnosis of this disorder, along with a brief review of various diagnostic criteria.

Small cell lung cancer (SCLC) is characterized by a relatively high rate of autoimmune phenomena. Paraneoplastic limbic encephalitis (PLE) is an autoimmune syndrome in which a non-neural tumor containing an antigen normally present in the nervous system precipitates an antibody attack on neural tissues. Patients with PLE usually present with rapidly progressive short-term memory deficits, confusion or even dementia. Palmar fasciitis and polyarthritis syndrome (PFPAS) is another autoimmune syndrome characterized by rheumatologic manifestations, especially involving the palms of the hands. We report a case of a 59-year old woman who presented with worsening neurological symptoms of two-week duration, and later coma. The combined clinical, serological, and imaging studies suggested a diagnosis of PLE. A chest computed tomographic scan showed a 1.2 cm-diameter mass in the upper lobe of the left lung that was surgically removed and showed SCLC. Following surgery, neurological symptoms rapidly improved, allowing the patient to receive adjuvant chemotherapy. While in remission for both SCLC and PLE, the patient developed pain, soft-tissue swelling, and stiffness in both palms, suggesting the diagnosis of PFPAS. Five months following the diagnosis of palmar fasciitis, SCLC relapsed with mediastinal and cervical lymphadenopathy. This case report underlines the continuous interaction of SCLC with the immune system, expressed by coexistence of two rare paraneoplastic diseases, PLE, and PFPAS, in a patient with SCLC. While symptoms related to PLE preceded the initial diagnosis of SCLC, other symptoms related to PFPAS preceded relapse.

Vaccines, adjuvants and autoimmunity.

Guimarães, Luísa Eça; Baker, Britain; Perricone, Carlo; Shoenfeld, Yehuda

2015-10-01

Vaccines and autoimmunity are linked fields. Vaccine efficacy is based on whether host immune response against an antigen can elicit a memory T-cell response over time. Although the described side effects thus far have been mostly transient and acute, vaccines are able to elicit the immune system towards an autoimmune reaction. The diagnosis of a definite autoimmune disease and the occurrence of fatal outcome post-vaccination have been less frequently reported. Since vaccines are given to previously healthy hosts, who may have never developed the disease had they not been immunized, adverse events should be carefully accessed and evaluated even if they represent a limited number of occurrences. In this review of the literature, there is evidence of vaccine-induced autoimmunity and adjuvant-induced autoimmunity in both experimental models as well as human patients. Adjuvants and infectious agents may exert their immune-enhancing effects through various functional activities, encompassed by the adjuvant effect. These mechanisms are shared by different conditions triggered by adjuvants leading to the autoimmune/inflammatory syndrome induced by adjuvants (ASIA syndrome). In conclusion, there are several case reports of autoimmune diseases following vaccines, however, due to the limited number of cases, the different classifications of symptoms and the long latency period of the diseases, every attempt for an epidemiological study has so far failed to deliver a connection. Despite this, efforts to unveil the connection between the triggering of the immune system by adjuvants and the development of autoimmune conditions should be undertaken. Vaccinomics is a field that may bring to light novel customized, personalized treatment approaches in the future. Copyright © 2015 Elsevier Ltd. All rights reserved.

Autoimmunity in Wiskott-Aldrich Syndrome: an unsolved enigma

Directory of Open Access Journals (Sweden)

Marco eCatucci

2012-07-01

Full Text Available Wiskott-Aldrich Syndrome (WAS is a severe X-linked Primary Immunodeficiency (PID that affects 1 to 10 out of 1 million male individuals. WAS is caused by mutations in the WAS Protein (WASP expressing gene that leads to the absent or reduced expression of the protein. WASP is a cytoplasmic protein that regulates the formation of actin filaments in hematopoietic cells. WASP deficiency causes many immune cell defects both in humans and in the WAS murine model, the Was-/- mouse. Both cellular and humoral immune defects in WAS patients contribute to the onset of severe clinical manifestations, in particular microthrombocytopenia, eczema, recurrent infections and a high susceptibility to develop autoimmunity and malignancies. Autoimmune diseases affect from 22% to 72% of WAS patients and the most common manifestation is autoimmune hemolytic anemia, followed by vasculitis, arthritis, neutropenia, inflammatory bowel disease and IgA nephropathy. Many groups have widely explored immune cell functionality in WAS partially explaining how cellular defects may lead to pathology. However, the mechanisms underlying the occurrence of autoimmune manifestations have not been clearly described yet. In the present review, we report the most recent progresses in the study of immune cell function in WAS that have started to unveil the mechanisms contributing to autoimmune complications in WAS patients.

Full Text Available Hypoglycemia was detected in a 15-year-old girl due to loss of consciousness. She was diagnosed with Graves' disease and was being treated with methimazole for the past 4 months. A paradoxically increased insulin levels was found when she suffered from the hypoglycemic episode. An imaging study showed no mass lesion in the pancreas, and insulin antibodies were found in the serum. She was diagnosed with insulin autoimmune syndrome. Her HLA typing was performed, and it revealed HLA-DRB1 *04:06. The patient was treated with a corticosteroid for 2 months. After discontinuing the steroid, the insulin antibody titer decreased dramatically, and she did not have any episode of hypoglycemia since. This is the first report of insulin autoimmune syndrome in a Korean girl, and we have revealed the connection between HLA type and insulin autoimmune syndrome in Korea.

Primary Biliary Cirrhosis-Related Autoimmune Hemolytic Anemia: Three Case Reports and Review of the Literature

Full Text Available The association between primary biliary cirrhosis (PBC and autoimmune hemolytic anemia (AIHA is uncommon; only fourteen such case reports have been described. In this report, three patients who developed AIHA on the basis of PBC underwent successful therapy with corticosteroids and ursodeoxycholic acid (UDCA. Patient 3 was more complicated, suffering from PBC, Evans syndrome, Sjögren syndrome and Klinefelter syndrome simultaneously. This has not previously been reported in the world literature. Review of all fifteen cases showed that there is a prominent occurrence sequence that AIHA might take place on the basis of PBC. With sufficient doses of corticosteroids or immunosuppressant therapy, besides hemolysis under effective control, liver function also improved. According to the criteria of secondary AIHA, we may call them PBC-related AIHA. Thus, patients with PBC with serum bilirubin levels rising suddenly should undergo screening for associated hemolysis. Recommended treatment for PBC-related AIHA includes sufficient doses of corticosteroids to control the hemolysis in the acute phase, and immunosuppressant or adequate dose of UDCA to maintain therapy. These case reports have been increasing in recent years, so further reserch is needed to illustrate the incidence and natural courses of these two organ-specific autoimmune diseases.

Overlap syndromes in which persons manifest clinical, histological, or immunological features of both hepatitis C infection and autoimmune hepatitis are well described. The discordant forms of treatment for hepatitis C and autoimmune hepatitis have made medical management of these patients difficult. We report our experience in using corticosteroids as first line therapy for the hepatitis C-autoimmune hepatitis overlap syndrome. Seven patients with this overlap syndrome (diagnosis based on the presence of serum hepatitis C antibody by RIBA and serum hepatitis C RNA by polymerase chain reaction, and serum hypergammaglobulinemia, elevated ANA or ASMA titers, or histological findings consistent with autoimmune hepatitis) were treated with prednisone with or without azathioprine or cyclosporine, and followed for a median duration of 44.5 months. Five patients (71%) showed improvement of median serum ALT level from 162 U/L to 38 U/L (p = 0.04) and median serum gamma-globulin from 2.1 g/dl to 1.4 g/dl (p = 0.04) by 6 months of therapy. The mean modified histological activity index score also decreased from 11.4 +/- 2.5 to 6.6 +/- 2.6 (p = 0.04) by at least 1 yr of therapy. One patient discontinued prednisone while taking azathioprine and experienced a rebound elevation of serum ALT that did not respond to retreatment with prednisone. Antiviral therapy was subsequently administered and resulted in biochemical and virologic response. Hepatitis C virus RNA remained detectable in all other patients. Corticosteroids are beneficial as a first line therapy for some patients with the hepatitis C-autoimmune overlap syndrome, resulting in appreciable biochemical and histological response but without viral eradication.

There is expanding knowledge about the phenotypic variability of patients with voltage gated potassium channel complex (VGKC) antibody mediated neurologic disorders. The phenotypes are diverse and involve disorders of the central and peripheral nervous systems. The central nervous system manifestations described in the literature include limbic encephalitis, status epilepticus, and acute encephalitis. We report a 4.5 year-old boy who presented with intractable Myoclonic Astatic Epilepsy (MAE) or Doose syndrome and positive VGKC antibodies in serum. Treatment with steroids led to resolution of seizures and electrographic normalization. This case widens the spectrum of etiologies for MAE to include autoimmunity, in particular VGKC auto-antibodies and CNS inflammation, as a primary or contributing factor. There is an evolving understanding of voltage gated potassium channel complex mediated autoimmunity in children and the role of inflammation and autoimmunity in MAE and other intractable pediatric epilepsy syndromes remains to be fully defined. A high index of suspicion is required for diagnosis and appropriate management of antibody mediated epilepsy syndromes.

Autoimmune lymphoproliferative syndrome (ALPS) is characterized by childhood onset of lymphadenopathy, hepatosplenomegaly, autoimmune cytopenias, elevated numbers of double-negative T (DNT) cells, and increased risk of lymphoma. Most cases of ALPS are associated with germline mutations of the FAS gene (type Ia), whereas some cases have been noted to have a somatic mutation of FAS primarily in their DNT cells. We sought to determine the proportion of patients with somatic FAS mutations among a group of our ALPS patients with no detectable germline mutation and to further characterize them. We found more than one-third (12 of 31) of the patients tested had somatic FAS mutations, primarily involving the intracellular domain of FAS resulting in loss of normal FAS signaling. Similar to ALPS type Ia patients, the somatic ALPS patients had increased DNT cell numbers and elevated levels of serum vitamin B(12), interleukin-10, and sFAS-L. These data support testing for somatic FAS mutations in DNT cells from ALPS patients with no detectable germline mutation and a similar clinical and laboratory phenotype to that of ALPS type Ia. These findings also highlight the potential role for somatic mutations in the pathogenesis of nonmalignant and/or autoimmune hematologic conditions in adults and children.

Asthma therapy with monoclonal antibodies is a promising and effective approach for those with a severe and refractory type of disease. Although such a targeted therapy is considered to be safe, unusual complications may occur. We present a case of a 45 year-old female patient with severe allergic asthma and chronic spontaneous urticaria, who developed autoimmune polyendocrine syndrome type 2 (APS-2) after 26 months of omalizumab administration. The patient was diagnosed with primary adrenal insufficiency (Addison's disease) and Hashimoto's thyroiditis accompanied by autoimmune atrophic gastritis. According to our knowledge this is the first description of APS-2 that developed in conjunction with omalizumab treatment, although we have no evidence that the observed phenomenon indicated a cause-effect relationship to omalizumab.

Previous research has suggested an inverse relationship between T-helper 2-related atopic disorders, such as asthma, and T-helper 1-related autoimmune diseases. One controversial hypothesis postulates that asthma provides a protective effect for the development of autoimmune-related disorders. To assess the rate of newly diagnosed autoimmune disorders in a large cohort of young adults. Using cross-sectional data from the Israeli Defense Force database, the authors analyzed the prevalence of autoimmune disorders in asthmatic and nonasthmatic military personnel between 1980 and 2003. A follow-up study traced newly diagnosed autoimmune disorders among asthmatic and nonasthmatic individuals from the time of enrollment in military service until discharge (22 and 36 months for women and men, respectively). General community. 307,367 male and 181,474 female soldiers in compulsory military service who were between 18 and 21 years of age. Cases of type 1 diabetes mellitus, vasculitis, immune thrombocytopenic purpura, inflammatory bowel disease, rheumatoid arthritis, and the antiphospholipid syndrome. Of 488,841 participants at enrollment, significantly more women than men had autoimmune disorders. Compared with asthmatic women, nonasthmatic women had a significantly higher prevalence of all autoimmune disorders except for the antiphospholipid syndrome. Type 1 diabetes mellitus, vasculitis, and rheumatoid arthritis were less prevalent in men with asthma than in those without. During the follow-up period, vasculitis and rheumatoid arthritis were more frequently diagnosed in nonasthmatic persons of both sexes. There was a significantly higher incidence of immune thrombocytopenic purpura, inflammatory bowel disease, and the antiphospholipid syndrome in nonasthmatic women and a statistically significantly higher incidence of type 1 diabetes mellitus in nonasthmatic men. The study was limited to a population of young military recruits; therefore, its findings are not necessarily

With growing use of nivolumab, rare but serious side effects have surfaced in some patients. We present a case of autoimmune haemolytic anaemia that developed after 39 cycles of nivolumab. A 78-year-old man with metastatic lung adenocarcinoma, refractory to multiple lines of chemotherapy was switched to nivolumab. After around 2 years of stable course on nivolumab, he developed transfusion-dependent anaemia with haemoglobin of 8.6 g/dL. Nivolumab was held immediately. Bone marrow biopsy findings were inconclusive of myelodysplastic syndrome. Further testing was suggestive of haemolysis with haptoglobin <10 mg/dL, elevated reticulocyte count and identification of immunoglobulin G antibody. Haemoglobin improved significantly with initiation of 1 mg/kg prednisone in addition to rituximab weekly × four doses. The development of transfusion-dependent anaemia with the exposure to cytotoxic chemotherapy usually raises the question for myelodysplastic syndrome. In contradiction, our patient was diagnosed to have a haematological autoimmune complication related to immunotherapy. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

Full Text Available Introduction. Insulin allergy is a rare complication of insulin therapy, especially in type 1 diabetes mellitus (T1DM. Key manifestations are hypersensitivity-related symptoms and poor metabolic control. T1DM, as well as insulin allergy, may develop in the context of autoimmune polyendocrine syndrome (APS, further complicating management. Case Report. A 17-year-old male patient, diagnosed with T1DM, was treated with various insulin therapy schemes over several months, which resulted in recurrent anaphylactoid reactions and poor glycemic control, after which he was referred to our Endocrinology and Immunology Department. A prick test was carried out for all commercially available insulin presentations and another insulin scheme was designed but proved unsuccessful. A desensitization protocol was started with Glargine alongside administration of Prednisone, which successfully induced tolerance. Observation of skin lesions typical of vitiligo prompted laboratory workup for other autoimmune disorders, which returned positive for autoimmune gastritis/pernicious anemia. These findings are compatible with APS type 4. Discussion. To our knowledge, this is the first documented case of insulin allergy in type 4 APS, as well as this particular combination in APS. Etiopathogenic components shared by insulin allergy and APS beg for further research in immunogenetics to further comprehend pathophysiologic aspects of these diseases.

To evaluate the frequency of cholestatic pattern in patients with autoimmune hepatitis (AIH) and to identify predictive factors associated with the development of the overlap syndrome. Eighty-two consecutive patients diagnosed with AIH at the referral centre between January 1998 and June 2002 were included in the study. The new scoring system modified by the International Autoimmune Hepatitis Group was used to classify patients as definite/probable. Overlap syndrome was considered when the patient had clinical, serological and histological characteristics of two conditions: AIH and primary biliary cirrhosis (PBC) or AIH and primary sclerosing cholangitis (PSC). From the 82 AIH patients (76 female and six male), 84.1% presented definite AIH (> 15 points) and 15.9% probable AIH (10 - 15 points). The frequency of the overlap syndrome was 20%: 13% with PBC and 7% with PSC. In the univariate analysis the overlap syndrome was associated with male gender (P = 0.01), age < 35 years (P < 0.0001), histopathological aspect of cholestasis (P < 0.0001), suboptimal response to treatment (P < 0.0001) and probable AIH (P < 0.0001). Age < 35 years, probable AIH and the absence of anti-nuclear antibody (ANA) have been identified as independent indicators of the overlap diagnosis by the logistic regression analysis. Patients with overlap syndrome between AIH and primary cholestatic liver disease are frequently diagnosed in clinical practice, representing 20% of AIH cases in our study. The independent predictive factors associated with the diagnosis of overlap syndrome are young age, ANA(-) profile, and probable diagnosis according with the scoring system for AIH.

Diabetes type 1(T1D) is the most frequent form of diabetes in children and young people, which essence is autoimmune destruction of pancreatic B cells islet. Co-occurrence of other autoimmune diseases is observed in children with T1D, the most often are: Hashimoto disease or coeliac disease. We report the case of the patient, who presents coincidence of T1D with other rare autoimmune diseases such as: Graves - Basedow disease, myasthenia gravis, vitiligo and IgA deficiency. All mentioned diseases significantly complicated both endocrine and diabetic treatment of our patient and they negatively contributed her quality of life. The clinical picture of the case allows to recognize one of the autoimmune polyendocrine syndromes: APS-3 and is associated with still high risk of developing another autoimmune disease. © Polish Society for Pediatric Endocrinology and Diabetology.

Thus, health care providers dealing with this patient group should be observant and test liberally for these conditions even before clinical symptoms......Individuals with Turner syndrome (TS) are prone to develop autoimmune conditions such as coeliac disease (CD), thyroiditis and type 1 diabetes (T1DM). The objective of the present study was to examine TS of various karyotypes for autoantibodies and corresponding diseases. This was investigated...... hypothyroid. Overall, 18% (19) presented with CD autoantibodies, of whom 26% (five) had CD. Anti-TPO and CD autoantibodies co-existed in 9% (10). Immunoglobulin A deficiency was found in 3% (three) of patients, who all had CD autoantibodies without disease. Among four patients with anti-GAD-65 none had T1DM...

Autoimmune Polyglandular Syndrome type 1 (APS-1) is a subtype of the autoimmune polyendocrine syndrome characterized by the simultaneous or sequential dysfunction of multiple endocrine or non-endocrine glands. A clinical diagnosis of APS-1 is typically based on the presence of at least two of three following criteria: chronic mucocutaneous candidiasis, hypoparathyroidism and adrenal insufficiency. The first identified causative mutated gene for APS-1 is autoimmune regulator (AIRE) encoding a critical transcription factor, which is primarily expressed in the medullary thymic epithelial cells (mTECs) for generating central immune tolerance. A wide range of chronic, debilitating complications, with no obvious correlation with genetics, makes a diagnosis of APS-1 challenging early in the disease course. Managing APS-1 is difficult due to its complexity, especially the intricate relationships within manifestations and genetic mutations. The past decades have witnessed dramatic progress in elucidating the function of AIRE and conducting large-scale cohort studies in APS-1. However, no clear evidence-based guidelines have been established in APS-1. In this review, we provide a detailed critical overview of the study history, epidemiology, clinical features, and related mechanisms of autoimmunity in APS-1, as well as currently available therapies for this autoimmune disorder.

2012-07-01

Full Text Available Immune dysregulation, Polyendocrinopathy, Enteropathy, X-linked (IPEX syndrome is a rare monogenic primary immunodeficiency (PID due to mutations of FOXP3, a key transcription factor for naturally occurring (n regulatory T (Treg cells. The dysfunction of Treg cells is the main pathogenic event leading to the multi-organ autoimmunity that characterizes IPEX syndrome, a paradigm of genetically determined PID with autoimmunity. IPEX has a severe early onset and can become rapidly fatal within the first year of life regardless of the type and site of the mutation. The initial presenting symptoms are severe enteritis and/or type 1 diabetes mellitus, alone or in combination with eczema and elevated serum IgE. Other autoimmune symptoms, such as hypothyroidism, cytopenia, hepatitis, nephropathy, arthritis, and alopecia, can develop in patients who survive the initial acute phase.The current therapeutic options for IPEX patients are limited. Supportive and replacement therapies combined with pharmacological immunosuppression are required to control symptoms at onset. However, these procedures can allow only a reduction of the clinical manifestations without a permanent control of the disease. The only known effective cure for IPEX syndrome is haematopoietic stem cell transplantation, but it is always limited by the availability of a suitable donor and the lack of specific guidelines for bone marrow transplant in the context of this disease.This review aims to summarize the clinical histories and genomic mutations of the IPEX patients described in the literature to date. We will focus on the clinical and immunological features that allow differential diagnosis of IPEX syndrome and distinguish it from other PID with autoimmunity. The efficacy of the current therapies will be reviewed, and possible innovative approaches, based on the latest highlights of the pathogenesis to treat this severe primary autoimmune disease of childhood, will be discussed.

Full Text Available A 71-year-old woman with severe right lower leg pain, edema and erythema was presented to the Emergency Department and was found to have an extensive deep vein thrombosis (DVT confirmed by ultrasound. She underwent an extensive evaluation due to her prior history of malignancy and new hypercoagulable state, but no evidence of recurrent disease was detected. Further investigation revealed pernicious anemia (PA, confirmed by the presence of a macrocytic anemia (MCV=115.8fL/red cell, Hgb=9.0g/dL, decreased serum B12 levels (56pg/mL, with resultant increased methylmalonic acid (5303nmol/L and hyperhomocysteinemia (131μmol/L, the presumed etiology of the DVT. The patient also suffered from autoimmune thyroid disease (AITD, and both antithyroglobulin and anti-intrinsic factor antibodies were detected. She responded briskly to anticoagulation with heparin and coumadin and treatment of PA with intramuscular vitamin B12 injections. Our case suggests that a DVT secondary to hyperhomocystenemia may represent the first sign of polyglandular autoimmune syndrome III-B (PAS III-B, defined as the coexistent autoimmune conditions AITD and PA. It is important to recognize this clinical entity, as patients may not only require acute treatment with vitamin B12 supplementation and prolonged anticoagulation, as in this patient, but may also harbor other autoimmune diseases.

Hyperthyroidism from autoimmune thyroiditis in a man with type 1 diabetes mellitus: a case report

Hirsch Irl B

2011-07-01

Full Text Available Abstract Introduction The presentation, diagnosis, clinical course and treatment of a man with hyperthyroidism secondary to autoimmune thyroiditis in the setting of type 1 diabetes mellitus has not previously been described. Case presentation A 32-year-old European-American man with an eight-year history of type 1 diabetes mellitus presented with an unintentional 22-pound weight loss but an otherwise normal physical examination. Laboratory studies revealed a suppressed thyroid-stimulating hormone concentration and an elevated thyroxine level, which are consistent with hyperthyroidism. His anti-thyroid peroxidase antibodies were positive, and his thyroid-stimulating immunoglobulin test was negative. Uptake of radioactive iodine by scanning was 0.5% at 24 hours. The patient was diagnosed with autoimmune thyroiditis. Six weeks following his initial presentation he became clinically and biochemically hypothyroid and was treated with thyroxine. Conclusion This report demonstrates that autoimmune thyroiditis presenting as hyperthyroidism can occur in a man with type 1 diabetes mellitus. Autoimmune thyroiditis may be an isolated manifestation of autoimmunity or may be part of an autoimmune polyglandular syndrome. Among patients with type 1 diabetes mellitus who present with hyperthyroidism, Graves' disease and other forms of hyperthyroidism need to be excluded as autoimmune thyroiditis can progress quickly to hypothyroidism, requiring thyroid hormone replacement therapy.

Autoimmune diseases are chronic conditions initiated by the loss of immunological tolerance to self-antigens. They constitute heterogeneous group of disorders, in which multiple alterations in the immune system result in a spectrum of syndromes that either target specific organs or affect the body systematically. Recent epidemiological studies have shown a possible shift of one autoimmune disease to another or the fact that more than one autoimmune disease may coexist in a single patient or in the same family. Numerous autoimmune diseases have been shown to coexist frequently with thyroid autoimmune diseases. AUTOIMMNUNE THYROID DISEASE AND OTHER ORGAN SPECIFIC NON-ENDOCRINE AUTOIMMUNE DISEASES: This part of the study reviews the prevalence of autoimmune thyroid disease coexisting with: pernicious anaemia, vitiligo, celiac disease, autoimmune liver disease, miastenia gravis, alopecia areata and sclerosis multiplex, and several recommendations for screening have been given. AUTOIMMUNE THYROID DISEASE AND OTHER ORGAN NON-SPECIFIC NON-ENDOCRINE AUTOIMMUNE DISEASES: Special attention is given to the correlation between autoimmune thyroid disease and rheumatoid arthritis, systemic lupus erythematosus, syndrome Sjögren, systemic sclerosis and mixed connective tissue disease. Screening for autoimmune thyroid diseases should be recommended in everyday clinical practice, in patients with primary organ-specific or organ non-specific autoimmune disease. Otherwise, in patients with primary thyroid autoimmune disease, there is no good reason of seeking for all other autoimmune diseases, although these patients have a greater risk of developing other autoimmune disease. Economic aspects of medicine require further analyzing of these data, from cost/benefit point of view to justified either mandatory screening or medical practitioner judgment.

Contactin-associated protein 2 (CASPR2) antibodies are originally associated with Morvan's syndrome and peripheral nerve hyper excitability. Our objective was to study retrospectively the clinical spectrum of CASPR2 antibody-positive patients in our hospital. This is a retrospective observational study. Patients treated at the Amrita Institute of Medical Sciences from May 2013 to April 2016, who were tested positive for CASPR2 antibodies, were included. A total of 1584 samples were tested in the neuroimmunology laboratory during the study period for voltage-gated potassium channel (VGKC) complex antibodies-leucine-rich glioma-inactivated protein 1 (LGI1) and CASPR2 antibodies. Thirty-four were positive for LGI1, 13 were positive for CASPR2, and 7 were for both (total 54-3.4% positivity). Of these 54 cases, 11 were treated in our hospital. Seven were positive for LGI1, three for CASPR2, and one for both. The patient who had both CASPR2 and LGI1 antibody positive had Morvan's syndrome. One patient with CASPR2 had neuromyotonia. The other patient was admitted with status epilepticus with a syndrome of parkinsonism and ataxia. The third patient had encephalopathy and myoclonus with a syndrome of parkinsonism and ataxia. Two of them underwent siddha treatment for other ailments prior to the onset of the disease for other ailments. Our short series shows the expanding spectrum of CASPR2 autoimmunity. Syndrome of parkinsonism and ataxia is an important manifestation of CASPR2 autoimmunity where we can offer a definitive treatment.

Guillain-Barre syndrome is a neurologic disorder that may appear after infection or major surgery. Guillain-Barré syndrome following cardiac surgery is rare and only based on case reports, and we review all of the published cases. A 52-year-old man after 5 months suffering from chest pain was referred to our hospital and underwent coronary artery bypass graft for 3 vessel disease. The patient was discharged without complication on the 5th postoperative day. He presented Guillain-Barré syndrome after 12 months. He has not completely recovered weakness of upper extremities grade 4/5 with atrophy of both upper extremities remains after 18 months. This disorder is similar to classic GBS. It is important to be alert to de novo autoimmune neurological disorders after cardiac surgery. These disorders are similar to classic autoimmune disease and treated with standard therapies.

Acquired immunodeficiency syndrome (AIDS) remains ill-defined by lists of symptoms, infections, tumors, and disorders in metabolism and immunity. Low CD4 cell count, severe loss of body weight, pneumocystis pneumonia, and Kaposi's sarcoma are the major disease indicators. Lines of evidence indicate that patients living with AIDS have both immunodeficiency and autoimmunity. Immunodeficiency is attributed to deficits in the skin- and mucosa-defined innate immunity, CD4 T cells and regulatory T cells, presumably relating human immunodeficiency virus (HIV) infection. The autoimmunity in AIDS is evident by: (1) overproduction of autoantibodies, (2) impaired response of CD4 cells and CD8 cells, (3) failure of clinical trials of HIV vaccines, and (4) therapeutic benefits of immunosuppression following solid organ transplantation and bone marrow transplantation in patients at risk of AIDS. Autoantibodies are generated in response to antigens such as debris and molecules de novo released from dead cells, infectious agents, and catabolic events. Disturbances in metabolic homeostasis occur at the interface of immunodeficiency and autoimmunity in the development of AIDS. Optimal treatments favor therapeutics targeting on the regulation of metabolism to restore immune homeostasis.

Abstract Autoimmune myositis encompasses various myositis-overlap syndromes, each being identified by the presence of serum marker autoantibodies. We describe a novel myositis-overlap syndrome in 4 patients characterized by the presence of a unique immunologic marker, autoantibodies to nuclear pore complexes. The clinical phenotype was characterized by prominent myositis in association with erosive, anti-CCP, and rheumatoid factor-positive arthritis, trigeminal neuralgia, mild interstitial lung disease, Raynaud phenomenon, and weight loss. The myositis was typically chronic, relapsing, and refractory to corticosteroids alone, but remitted with the addition of a second immunomodulating drug. There was no clinical or laboratory evidence for liver disease. The prognosis was good with 100% long-term survival (mean follow-up 19.5 yr). By indirect immunofluorescence on HEp-2 cells, sera from all 4 patients displayed a high titer of antinuclear autoantibodies (ANA) with a distinct punctate peripheral (rim) fluorescent pattern of the nuclear envelope characteristic of nuclear pore complexes. Reactivity with nuclear pore complexes was confirmed by immunoelectron microscopy. In a cohort of 100 French Canadian patients with autoimmune myositis, the nuclear pore complex fluorescent ANA pattern was restricted to these 4 patients (4%). It was not observed in sera from 393 adult patients with systemic sclerosis (n = 112), mixed connective tissue disease (n = 35), systemic lupus (n = 94), rheumatoid arthritis (n = 45), or other rheumatic diseases (n = 107), nor was it observed in 62 normal adults. Autoantibodies to nuclear pore complexes were predominantly of IgG isotype. No other IgG autoantibody markers for defined connective tissue diseases or overlap syndromes were present, indicating a selective and highly focused immune response. In 3 patients, anti-nuclear pore complex autoantibody titers varied in parallel with myositis activity, suggesting a pathogenic

Wolfram syndrome is a rare neurodegenerative and genetic disorder, characterized by insulin-dependent diabetes mellitus, caused by non-autoimmune loss of β cells, as well as optic atrophy; the disease is also known as DIDMOAD (diabetes insipidus, diabetes mellitus, optic atrophy, and deafness). Patients that demonstrate diabetes mellitus are also affected by: optic atrophy in the first decade of their life, diabetes insipidus and sensorineural deafness in the second decade, and urinary tract and neurological abnormalities in the third decade of their life. Patients with Wolfram syndrome usually die due to central respiratory failures caused by brain stem atrophy in their third or at the beginning of their fourth decade of life. The authors present a case of two female siblings with diagnosed Wolfram syndrome that have been diagnosed with diabetes mellitus, optic atrophy, and urological abnormalities. Early diagnosis and adequate hormonal supplementation can improve their quality of life. © Polish Society for Pediatric Endocrinology and Diabetology.

B+NK+SCID (severe combined immunodeficiency) due to IL7Rα deficiency represents approximately 10% of American SCID cases. To better understand the spectrum of autoimmune disorders associated with IL7Rα deficiency, we describe two unrelated IL7Rα-deficient female SCID infants whose clinical picture was dominated by autoimmune manifestations: one with intrauterine Omenn syndrome (OS) and another with persistent thrombocytopenic purpura since 4months of age. The OS baby harbored a homozygous p.C118Y mutation in IL7R. She presented dense eosinophilic infiltrates in several organs, including pancarditis, which may have contributed to her death (on the 2nd day of life). B cells were observed in lymph nodes, spleen, bone marrow and thymus. The second patient harbored compound heterozygous p.C118Y and p.I121NfsX8 mutations. She underwent a successful unrelated cord blood transplant. In conclusion, early OS can be observed in patients with IL7R mutations, and autoimmune cytopenias could also complicate the clinical course of SCID babies with this type of defect. Copyright © 2014.

2009-04-01

Full Text Available Abstract Introduction Autoimmune hemolytic anemia in children younger than 2 years of age is usually characterized by a severe course, with a mortality rate of approximately 10%. The prolonged immunosuppression following specific treatment may be associated with a high risk of developing severe infections. Recently, the use of monoclonal antibodies (rituximab has allowed sustained remissions to be obtained in the majority of pediatric patients with refractory autoimmune hemolytic anemia. Case presentation We describe the case of an 8-month-old Caucasian girl affected by a severe form of autoimmune hemolytic anemia, which required continuous steroid treatment for 16 months. Thereafter, she received 4 weekly doses of rituximab (375 mg/m2/dose associated with steroid therapy, which was then tapered over the subsequent 2 weeks. One month after the last dose of rrituximab, she presented with recurrence of severe hemolysis and received two more doses of rrituximab. The patient remained in clinical remission for 7 months, before presenting with a further relapse. An alternative heavy immunosuppressive therapy was administered combining cyclophosphamide 10 mg/kg/day for 10 days with methylprednisolone 40 mg/kg/day for 5 days, which was then tapered down over 3 weeks. While still on steroid therapy, the patient developed an interstitial pneumonia with Acute Respiratory Distress Syndrome, which required immediate admission to the intensive care unit where extracorporeal membrane oxygenation therapy was administered continuously for 37 days. At 16-month follow-up, the patient is alive and in good clinical condition, with no organ dysfunction, free from any immunosuppressive treatment and with a normal Hb level. Conclusions This case shows that aggressive combined immunosuppressive therapy may lead to a sustained complete remission in children with refractory autoimmune hemolytic anemia. However, the severe life-threatening complication presented by our

Summary We hypothesized that sirolimus, an mTOR inhibitor, may be effective in patients with autoimmune lymphoproliferative syndrome (ALPS) and treated patients who were intolerant to or failed other therapies. Four patients were treated for autoimmune cytopenias; all had a rapid complete or near complete response. Two patients were treated for autoimmune arthritis and colitis, demonstrating marked improvement. Three patients had complete resolution of lymphadenopathy and splenomegaly and all patients had a reduction in double negative T cells, a population hallmark of the disease. Based on these significant responses, we recommend that sirolimus be considered as second-line therapy for patients with steroid-refractory disease. PMID:19208097

Full Text Available Hematopoietic stem cell transplantation (HSCT can either cause or eliminate autoimmune disease. Here, we report two cases. One was a 33-year-old woman with myelodysplastic syndrome (refractory anemia who received bone marrow transplantation from her human leukocyte antigen (HLA-identical sister who had a history of Graves' disease. Antithyroid antibodies, including antimicrosomal antibody and antithy-roglobulin antibody, appeared 4 months after transplantation. Clinical hyperthyroidism appeared 7 months after transplantation, and a hypothyroid state was noted 2 months later. The other case was a 50-year-old woman with Sjögren's syndrome and hypothyroidism who was diagnosed with peripheral T cell non-Hodgkin's lymphoma. She received allogeneic peripheral blood stem cell transplantation (PBSCT from her histocompatible sister owing to only partial response to traditional chemotherapy. Cure of lymphoma and remission of Sjögren's syndrome was noted 4 years after PBSCT. These two illustrative cases, one of acquisition of hyperthyroidism and the other of remission of Sjögren's syndrome after transplantation, highlights that HSCT can induce adoptive autoimmune disease or cure coincidental autoimmune disease. Donor selection and attentive monitoring is required in such circumstances.

Full Text Available A 6-year-old girl underwent ureterocystoneostomy (UCN because of left flank pain due to delayed onset of ureteral stenosis one and a half years after endoscopic dextranomer/hyaluronic acid copolymer (Deflux injection for the treatment of vesicoureteral reflux (VUR. Histopathological examination indicated chronic inflammation with abundant eosinophils characteristic of a reaction to Deflux. Several autoimmune diseases developed during the treatment for ureteral stenosis. First, 2 weeks prior to the onset of left flank pain, she was diagnosed as having systemic lupus erythematosus. Finally, she died of pulmonary hemorrhage due to thrombotic thrombocytopenic purpura 4 months after UCN. The fatal outcome in this case was suspected to be caused by autoimmune syndrome induced by adjuvants, which in this case was the hyaluronic acid polymer injected into the ureteric orifice for the treatment of VUR.

Kleine–Levin Syndrome: A case report

Full Text Available The Kleine–Levin Syndrome is a differential diagnosis for patients with diurnal excessive sleepiness and a suspicion of narcolepsy. It is characterized by paroxysmal attacks of diurnal excessive sleepiness, associated with one or more symptoms of hyperphagia, hypersexuality, coprolalia and copropraxia. During crisis intervals, there are no symptoms. This pathology predominantly manifests itself in teenagers, being more frequent among males. The course of this disease is unpredictable, with variable duration and frequency. The most accepted physiopathology is that of a hypothalamic dysfunction, although and recently, there has appeared a hypothesis of a post-infectious autoimmune disorder. These patients show an elevated body mass index, which can predispose to association with comorbidities such as the sleep obstructive apnea syndrome. Treatment involves medications with different effects, but there is no specific and effective therapy. Our article shows a classic case of Kleine–Levin Syndrome associated with sleep obstructive apnea syndrome, a rare association in the literature.

Autoimmune pancreatitis (AuP) is a chronic pancreatic inflammation secondary to an underlying autoimmune mechanism. After early reports of a particular type of pancreatitis associated with hypergammaglobulinemia, others asserted that there is an autoimmune mechanism involved in some patients with chronic pancreatitis. In 1995 AuP was first described as a distinct clinical entity. Since then, there have been many documented cases of AuP in Japan, and now, perhaps due to increased awareness, more cases are being reported in Europe and the United States. Herein we present our experience with 3 cases of AuP and we review the relevant literature. These 3 cases demonstrate the difficulties that exist in making the diagnosis of AuP and the impact that the diagnosis can have on patient management.

2007-01-01

Autoimmune polyendocrine syndrome (APS) is the association of autoimmune endocrine diseases, with other autoimmune nonendocrine disorders. APS types 1, 2 and 4 include autoimmune adrenalitis; this suggests the presence of autoantibodies. A specific serological marker for these is the anti 21- hydroxilase autoantibody (a21-OH). APS type 2 is the association of autoimmune adrenalitis, to autoimmune thyroid disease and/or diabetes mellitus, all these are induced by autoantibodies. Alopecia, vitiligo, myasthenia and other manifestations can be minor components. We sought to establish the prevalence of seric a21-OH in patients with positive anti-microsomal fraction autoantibodies, autoimmune thyroid disease and/or non-endocrine autoimmune diseases. We also aimed to diagnose incomplete forms of APS and to follow up patients at risk of progression to complete forms of APS. A population of 72 patients and another of 60 controls with negative anti-microsomal fraction autoantibodies were studied. Elevated seric a21-OH were found in two patients. Patient A with 47 U/ml had autoimmune hypothyroidism and myasthenia; and patient B with 8.75 U/ml had autoimmune hypothyrodism and vitiligo; they both lacked adrenal insufficiency. Seric a21-OH had a prevalence of 2.8%. Regarding the adrenal component, patients A and B had an incomplete and latent APS type 2. Considering a21-OH as markers of latent endocrine autoimmune diseases and taking into account the eventual risk of developing clinical manifestations, periodic biochemical and clinical follow-ups are recommended.

Specific autoimmune and inflammatory rheumatic diseases have been associated with an increased risk of malignant lymphomas. Conditions such as rheumatoid arthritis (RA), primary Sjögren’s syndrome (pSS), systemic lupus erythematosus (SLE), dermatomyositis, and celiac disease have been consistently linked to malignant lymphomas. Isolated cases of lymphomas associated with spondyloarthropathies and autoinflammatory diseases have also been reported. Direct association between autoimmunity and ly...

Thyrotropinomas (TSHomas) are rare pituitary adenomas, particularly in childhood. We present here the case of an 11-year-old boy with type 1 autoimmune polyglandular syndrome (APS1) and TSHoma which was diagnosed by elevated thyroid - stimulating hormone and thyroid hormones levels without evident clinical signs of hyperthyroidism. He was underwent partial resection of the tumor via transsphenoidal approach and subsequently radiation therapy. Consequently, 1 year after radiotherapy, the patient developed growth hormone deficiency, three and half years after radiation became euthyroid, and five and half years after treatment - hypothyroid. This is the first case of the coexistence of these two rare endocrine diseases in one patient.

Full Text Available The autoimmune polyendocrinopathy syndrome type 1 (APS-1, also known as candidiasis ectodermal-autoimmune polyendocrinopathy-dystrophy (APECED, it is a rare autosomal recessive disorder caused by mutations in the autoimmune regulator gene (AIRE. Therefore, it is immunologically characterized by cell attack and / or antibodymediated generating the destruction of target organs. Furthermore, it is characterized by the pathognomonic triad chronic candidiasis, hypoparathyroidism and Addison's disease with many other endocrine and non-endocrine events. Soon, the diagnosis is made based on the presence of two of the three classic features and treatment aims to control the numerous deficiencies that patients may present. This literature review was aimed at understanding the involvement of AIRE gene in relation to immunological aspects present and, consequently, clinical manifestations of this disease. Thus, evidence of the need to broaden the discussion about this disease, in order to improve the quality of life of patients by early diagnosis and treatment and are in accordance with the clinical manifestations of each patient. Thereby, qualitative research involved scientific articles from electronic journals LILACS (Latin American and Caribbean, SCIELO (Scientific Electronic Library Online and NCBI (National Center for Biotechnology Information, between the years 2009 and 2016. Pursuant to, there is the relevance of this review, it is noted that, although the authors converge on views on this syndrome, there are still many unclear matters with regard to the mechanisms of the disease. This highlights the need to promote more discussion on this topic.

An 18-year-old boy presented with upper gastrointestinal bleeding and jaundice. Investigations revealed coarse hepatomegaly, splenomegaly and advanced oesophageal varices. Blood reports showed marked rise of alkaline phosphatase and more than twofold rise of transaminases and IgG. Liver histology was suggestive of piecemeal necrosis, interphase hepatitis and bile duct proliferation. Antinuclear antibody was positive in high titre along with positive antismooth muscle antibody and antimitochondrial antibody. The patient was positive for human leukocyte antigen DR3 type. Although an 'overlap' syndrome exists between autoimmune hepatitis (AIH) and primary biliary cirrhosis (PBC), a cholestatic variant of AIH, a rare 'outlier' syndrome could not be excluded in our case. Moreover, 'the chicken or the egg', AIH or PBC, the dilemma for the internists continued. The patient was put on steroid and ursodeoxycholic acid with unsatisfactory response. The existing international criteria for diagnosis of AIH are not generous enough to accommodate its variant forms.

Heparin-induced thrombocytopenia (HIT) is a drug-induced, immunoglobulin G medicated autoimmune disorder associated with several negative clinical outcomes including increased morbidity, mortality, and increased medical costs. Previous studies have shown associations between comorbid autoimmune diseases, but there is little known about associations between HIT and autoimmunity. To provide clinical data to suggest an association between HIT and autoimmunity. Retrospective chart review of 59 cases with a diagnosis of HIT and 251 matched controls without a HIT diagnosis, comparing the prevalence of autoimmunity in each group. A single, large upper Midwest health care system. Patients with a diagnosis of HIT were significantly more likely to have a comorbid autoimmune disease than those without a HIT diagnosis (55.9% vs 10.8%, P HIT were significantly more likely to have a diagnosis of antiphospholipid syndrome (15.3% vs 0.0%, P HIT were significantly older than controls ( P HIT and autoimmune disease and suggests a need for more research into the relationship between HIT and autoimmunity. These results could alter the anticoagulation management of venous thromboembolism and acute coronary syndrome in patients with a previously identified autoimmune disease.

2017-11-01

Full Text Available Cholangiocarcinoma (CCA is a very aggressive and lethal tumor, which arises from the epithelial cells of bile ducts. CCA comprises about 3% of all gastrointestinal malignancies and its incidence is on the rise in the recent years. Anatomically, it is classified into intrahepatic, perihilar, or extrahepatic (distal CCA. There are a number of risk factors associated with CCA including primary sclerosing cholangitis, fibropolycystic liver disease, parasitic infection, viral hepatitis, chronic liver disease, and genetic disorders like Lynch syndrome. Autoimmune hepatitis is also recently reported to have an association with development of CCA. We report an interesting case of perihilar CCA in the setting of autoimmune hepatitis along with a literature review. This case highlights the importance of early treatment and close clinical follow-up of patients with autoimmune hepatitis for development of CCA.

Full Text Available Antibodies to GAD-65 have been implicated in the pathogenesis of type 1 diabetes , limbic encephalitis and Stiff person syndrome, however these diseases rarely occur concurrently. We intend to present a rare case of 35 year old female who was recently diagnosed as having type 1 diabetes presented with 1½ month history of recurrent seizures, subacute onset gait ataxia, dysathria, psychiatric disturbance and cognitive decline. No tumor was found on imaging and the classic paraneoplastic panel was negative. Cerebrospinal fluid and blood was positive for GAD-65 antibodies.Patient showed significant improvement with immunomodulatory therapy. Association of GAD-65 antibodies has been found with various disorders including type 1 diabetes, limbic encephalitis, Stiff person syndrome,cerebellar ataxia and palatal myoclonus.This case presents with unique combination of type 1 diabetes, Stiff person syndrome and limbic encephalitis associated with GAD-65 antibodies that is responsive to immunotherapy. It also highlights the emerging concept of autoimmunity in the causation of various disorders and there associations.

Full Text Available We report the case of a 14-year-old girl who developed postural orthostatic tachycardia syndrome (POTS with chronic fatigue 2 months following Gardasil vaccination. The patient suffered from persistent headaches, dizziness, recurrent syncope, poor motor coordination, weakness, fatigue, myalgias, numbness, tachycardia, dyspnea, visual disturbances, phonophobia, cognitive impairment, insomnia, gastrointestinal disturbances, and a weight loss of 20 pounds. The psychiatric evaluation ruled out the possibility that her symptoms were psychogenic or related to anxiety disorders. Furthermore, the patient tested positive for ANA (1:1280, lupus anticoagulant, and antiphospholipid. On clinical examination she presented livedo reticularis and was diagnosed with Raynaud’s syndrome. This case fulfills the criteria for the autoimmune/auto-inflammatory syndrome induced by adjuvants (ASIA. Because human papillomavirus vaccination is universally recommended to teenagers and because POTS frequently results in long-term disabilities (as was the case in our patient, a thorough follow-up of patients who present with relevant complaints after vaccination is strongly recommended.

Full Text Available Sjogren%u2019s syndrome is a chronic autoimmune disease characterized by xerostomia and xerophthalmia, known as the %u2018sicca symptoms%u2019. Patients with Sjogren%u2019s syndrome, characteristically have positive nuclear and cytoplasmic antigens, typically Anti-Ro/SSA and Anti-La/SSB because of lymphocytic infiltration of the exocrine glands. Patients with primary Sjogren%u2019s syndrome, develop systemic complications, non-Hodgkin lymphoma being the most feared of these. We describe here a case of Sjogren%u2019s syndrome with basal cell carcinoma, which presented with an ulcerated lesion on nasal dorsum.

Full Text Available Background/AimsOverlap syndrome of autoimmune hepatitis (AIH and primary biliary cirrhosis (PBC (AIH-PBC overlap syndrome is a rare disease that has not been clearly characterized in Korean patients. This study investigated the clinical features of AIH-PBC overlap syndrome compared with those of AIH and PBC alone.MethodsThis retrospective cohort study included 158 consecutive patients who were diagnosed as AIH (n=61, PBC (n=81, or AIH-PBC overlap syndrome (n=9 based on the Paris and the International Autoimmune Hepatitis Group (IAIHG criteria from 2001 to 2011 in Korea. We compared the clinical features of these three groups retrospectively, including their biochemical characteristics, treatments, responses, and clinical outcomes.ResultsThe AIH-PBC overlap syndrome patients exhibited biochemical characteristics of both AIH and PBC, and showed a similar response to ursodeoxycholic acid (UDCA monotherapy as for the PBC patients. However, the response of AIH-PBC overlap syndrome patients to UDCA and steroid combination therapy was worse than the response of AIH patients to steroid-based therapy (P=0.024. Liver cirrhosis developed more rapidly in AIH-PBC overlap syndrome patients than in AIH patients group (P=0.013, but there was no difference between AIH-PBC overlap syndrome patients and PBC patients. The rates of developing hepatic decompensation did not differ significantly between the groups.ConclusionsThe AIH-PBC overlap syndrome patients exhibited a worse response to UDCA and steroid combination therapy and a faster cirrhotic progression compared with AIH patients.

A rare case of the insulin autoimmune syndrome (IAS) accompanied by insulin receptor anomaly is reported. Antibodies to insulin and insulin receptor were determined in the patient with severe hypoglycaemia before and after the treatment with prednisolone. Titers of antibody to insulin and insulin receptors were 73.0% and 41.5%, respectively. Drug-induced lymphocyte stimulation tests were all negative for the suspicious drugs. Her HLA-DR was DRB1*0403/04051. Following steroid therapy, the formation of antibodies was suppressed and alleviated her symptoms. Scatchard analysis yielded findings specific to polyclonal antibodies. The changes in autoantibodies resulted in alleviation of the hypoglycemic symptoms as a result of steroid therapy.

Opsoclonus-myoclonus syndrome (OMS) is a rare neurological disease in childhood which can be associated with neuroblastoma. Since autoantibodies have been detected in some patients with OMS, an autoimmune etiology is suspected. We compared the prevalence of autoimmune disorders and autoantibodies in parents of children with OMS and in a group of controls of same age and sex. Autoimmune diseases were found in 15.8% of the parents of OMS children, but only in 2.0% of the controls (pOMS parents (42.8% vs. 8.0%, pOMS parents also had significantly more autoantibodies against CNS structures than the controls (pOMS and may also hint to a genetic susceptibility for OMS.

Autoimmune myositis encompasses various myositis-overlap syndromes, each being identified by the presence of serum marker autoantibodies. We describe a novel myositis-overlap syndrome in 4 patients characterized by the presence of a unique immunologic marker, autoantibodies to nuclear pore complexes. The clinical phenotype was characterized by prominent myositis in association with erosive, anti-CCP, and rheumatoid factor-positive arthritis, trigeminal neuralgia, mild interstitial lung disease, Raynaud phenomenon, and weight loss. The myositis was typically chronic, relapsing, and refractory to corticosteroids alone, but remitted with the addition of a second immunomodulating drug. There was no clinical or laboratory evidence for liver disease. The prognosis was good with 100% long-term survival (mean follow-up 19.5 yr).By indirect immunofluorescence on HEp-2 cells, sera from all 4 patients displayed a high titer of antinuclear autoantibodies (ANA) with a distinct punctate peripheral (rim) fluorescent pattern of the nuclear envelope characteristic of nuclear pore complexes. Reactivity with nuclear pore complexes was confirmed by immunoelectron microscopy. In a cohort of 100 French Canadian patients with autoimmune myositis, the nuclear pore complex fluorescent ANA pattern was restricted to these 4 patients (4%). It was not observed in sera from 393 adult patients with systemic sclerosis (n = 112), mixed connective tissue disease (n = 35), systemic lupus (n = 94), rheumatoid arthritis (n = 45), or other rheumatic diseases (n = 107), nor was it observed in 62 normal adults.Autoantibodies to nuclear pore complexes were predominantly of IgG isotype. No other IgG autoantibody markers for defined connective tissue diseases or overlap syndromes were present, indicating a selective and highly focused immune response. In 3 patients, anti-nuclear pore complex autoantibody titers varied in parallel with myositis activity, suggesting a pathogenic link to

Full Text Available Antiphospholipid syndrome (APS is an autoimmune disease which can be primary or secondary to other autoimmune conditions and is defined by the occurrence of arterial or venous thrombosis, or pregnancy morbidity associated with persistently positive antiphospholipid antibodies (aPLA. The kidney may be affected by thrombosis at any level of its vasculature. When small vessels are involved, this results in thrombotic microangiopathy (TMA, which can manifest as either acute vaso-occlusive or chronic vascular lesions in glomeruli, arterioles and interlobular arteries. We report the case of 26-year-old man, with a previous medical history suggestive of APS, who was found to have a small elevation in serum creatinine. A kidney biopsy was performed and revealed features of chronic TMA. Anticoagulation was begun and kidney function remained stable. However, one year later, upon suspension of anticoagulation, the patient developed acute kidney injury and a second kidney biopsy showed acute TMA. This case describes different manifestations of antiphospholipid syndrome nephropathy (APSN and highlights the importance of anticoagulation for thrombosis prevention.

The role of parvovirus B19 in the pathogenesis of autoimmunity and autoimmune disease.

Science.gov (United States)

Kerr, Jonathan R

2016-04-01

Human parvovirus B19 is a single-stranded DNA virus which preferentially targets the erythroblasts in the bone marrow. B19 infection commonly causes erythema infectiosum, arthralgia, fetal death, transient aplastic crisis in patients with shortened red cell survival, and persistent infection in people who are immunocompromised. Less common clinical manifestations include atypical skin rashes, neurological syndromes, cardiac syndromes, and various cytopenias. B19 infection has also been associated with development of a variety of different autoimmune diseases, including rheumatological, neurological, neuromuscular, cardiovascular, haematological, nephrological and metabolic. Production of a variety of autoantibodies has been demonstrated to occur during B19 infection and these have been shown to be key to the pathogenesis of the particular disease process in a significant number of cases, for example, production of rheumatoid factor in cases of B19-associated rheumatoid arthritis and production of anti-glutamic acid decarboxylase (GAD) in patients with B19-associated type 1 diabetes mellitus. B19 infection has also been associated with the development of multiple autoimmune diseases in 12 individuals. Documented mechanisms in B19-associated autoimmunity include molecular mimicry (IgG antibody to B19 proteins has been shown to cross react with a variety of recognised human autoantigens, including collagen II, keratin, angiotensin II type 1 receptor, myelin basic protein, cardiolipin, and platelet membrane glycoprotein IIb/IIIa), B19-induced apoptosis with presentation of self-antigens to T lymphocytes, and the phospholipase activity of the B19 unique VP1 protein.

HES is often attributed to neoplastic or reactive causes, such as chronic eosinophilic leukemia, although a majority of cases remains unexplained and are considered idiopathic. Here, we review the current diagnosis and management of HES and present a unique case of profound hypereosinophilia associated with warm autoimmune hemolytic anemia requiring intensive management. This case clearly illustrates the limitations of current knowledge with respect to hypereosinophilia syndrome as well as the challenges associated with its classification and management.

2016-11-01

Full Text Available Puumala hantavirus (PUUV infection causes nephropathia epidemica (NE, a relatively mild form of haemorrhagic fever with renal syndrome (HFRS. Hypophyseal haemorrhage and hypopituitarism have been described in case reports on patients with acute NE. Chronic hypopituitarism diagnosed months or years after the acute illness has also been reported, without any signs of a haemorrhagic aetiology. The mechanisms leading to the late-onset hormonal defects remain unknown. Here, we present a case of NE-associated autoimmune polyendocrinopathy and hypopituitarism presumably due to autoimmune hypophysitis. Thyroid peroxidase antibody seroconversion occurred between 6 and 12 months, and ovarian as well as glutamate decarboxylase antibodies were found 18 months after acute NE. Brain MRI revealed an atrophic adenohypophysis with a heterogeneous, low signal intensity compatible with a sequela of hypophysitis. The patient developed central (or mixed central and peripheral hypothyroidism, hypogonadism and diabetes insipidus, all requiring hormonal replacement therapy. This case report suggests that late-onset hormonal defects after PUUV infection may develop by an autoimmune mechanism. This hypothesis needs to be confirmed by prospective studies with sufficient numbers of patients.

To provide an overview of paraneoplastic autoimmune disorders presenting with various movement disorders. The spectrum of paraneoplastic autoimmune disorders has been expanding with the discovery of new antibodies against cell surface and intracellular antigens. Many of these paraneoplastic autoimmune disorders manifest as a form of movement disorder. With the discovery of new neuronal antibodies, an increasing number of idiopathic or neurodegenerative movement disorders are now being reclassified as immune-mediated movement disorders. These include anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis which may present with orolingual facial dyskinesia and stereotyped movements, CRMP-5 IgG presenting with chorea, anti-Yo paraneoplastic cerebellar degeneration presenting with ataxia, anti-VGKC complex (Caspr2 antibodies) neuromyotonia, opsoclonus-myoclonus-ataxia syndrome, and muscle rigidity and episodic spasms (amphiphysin, glutamic acid decarboxylase, glycine receptor, GABA(A)-receptor associated protein antibodies) in stiff-person syndrome. Movement disorders may be a presentation for paraneoplastic autoimmune disorders. Recognition of these disorders and their common phenomenology is important because it may lead to the discovery of an occult malignancy. Copyright © 2017 Elsevier Ltd. All rights reserved.

Autoimmunity and primary immunodeficiency: two sides of the same coin?

Science.gov (United States)

Schmidt, Reinhold E; Grimbacher, Bodo; Witte, Torsten

2017-12-19

Autoimmunity and immunodeficiency were previously considered to be mutually exclusive conditions; however, increased understanding of the complex immune regulatory and signalling mechanisms involved, coupled with the application of genetic analysis, is revealing the complex relationships between primary immunodeficiency syndromes and autoimmune diseases. Single-gene defects can cause rare diseases that predominantly present with autoimmune symptoms. Such genetic defects also predispose individuals to recurrent infections (a hallmark of immunodeficiency) and can cause primary immunodeficiencies, which can also lead to immune dysregulation and autoimmunity. Moreover, risk factors for polygenic rheumatic diseases often exist in the same genes as the mutations that give rise to primary immunodeficiency syndromes. In this Review, various primary immunodeficiency syndromes are presented, along with their pathogenetic mechanisms and relationship to autoimmune diseases, in an effort to increase awareness of immunodeficiencies that occur concurrently with autoimmune diseases and to highlight the need to initiate appropriate genetic tests. The growing knowledge of various genetically determined pathologic mechanisms in patients with immunodeficiencies who have autoimmune symptoms opens up new avenues for personalized molecular therapies that could potentially treat immunodeficiency and autoimmunity at the same time, and that could be further explored in the context of autoimmune rheumatic diseases.

Insulin autoimmune syndrome (IAS) is a condition characterized by hypoglycemia associated with the presence of autoantibodies to insulin in patients who have not been injected with insulin. A female patient (aged 16 years and 3 months) presented with the complaint of being overweight. Physical examination revealed a body weight of 78.2 kg (+2.6 SD) and a height of 167 cm (+0.73 SD). While the patient's fasting blood glucose level was found to be 40 mg/dl, blood ketone was negative and the serum insulin level was determined as 379 mIU/ml. The patient was diagnosed with hyperinsulinemic hypoglycemia. Abdominal ultrasound, pancreas MRI and endoscopic ultrasound were normal. The daily blood glucose profile revealed postprandial hyperglycemia and reactive hypoglycemia in addition to fasting hypoglycemia. The results of anti-insulin antibody measurements were as high as 41.8% (normal range 0-7%). A 1,600-calorie diet containing 40% carbohydrate and divided into 6 meals a day was given to the patient. Simple sugars were excluded from the diet. Hypoglycemic episodes were not observed, but during 2 years of observation, serum levels of insulin and anti-insulin antibodies remained elevated. In all hyperinsulinemic hypoglycemia cases, IAS should be considered in the differential diagnosis and insulin antibody measurements should be carried out. © 2014 S. Karger AG, Basel.

Autoimmune/Inflammatory Arthritis Associated Lymphomas: Who Is at Risk?

Directory of Open Access Journals (Sweden)

Sujani Yadlapati

2016-01-01

Full Text Available Specific autoimmune and inflammatory rheumatic diseases have been associated with an increased risk of malignant lymphomas. Conditions such as rheumatoid arthritis (RA, primary Sjögren’s syndrome (pSS, systemic lupus erythematosus (SLE, dermatomyositis, and celiac disease have been consistently linked to malignant lymphomas. Isolated cases of lymphomas associated with spondyloarthropathies and autoinflammatory diseases have also been reported. Direct association between autoimmunity and lymphomagenesis has been reinforced by large epidemiological studies. It is still uncertain whether disease specific determinants or phenotypic or treatment related characteristics increase likelihood of lymphomagenesis in these patients. For example, recent literature has indicated a positive correlation between severity of inflammation and risk of lymphomas among RA and Sjögren’s syndrome patients. It is also debated whether specific lymphoma variants are more commonly seen in accordance with certain chronic autoimmune arthritis. Previous studies have revealed a higher incidence of diffuse large B-cell lymphomas in RA and SLE patients, whereas pSS has been linked with increased risk of mucosa-associated lymphoid tissue lymphoma. This review summarizes recent literature evaluating risk of lymphomas in arthritis patients and disease specific risk determinants. We also elaborate on the association of autoimmune arthritis with specific lymphoma variants along with genetic, environmental, and therapeutic risk factors.

The significance of bile duct injury and ductular reaction in biopsies from autoimmune hepatitis patients is not clear. We aim to establish the prevalence and clinical relevance of both phenomena in autoimmune hepatitis. Cases of newly diagnosed, untreated autoimmune hepatitis without overlap syndrome were selected. Pretreatment and follow up biopsies were scored for inflammation, fibrosis, bile ductal injury and ductular reaction. Thirty-five cases were studied of whom 14 cases had follow up biopsies. Bile duct injury was present in 29 cases (83%), mostly in a PBC-like pattern and was not correlated with demographical or laboratory findings. Ductular reaction, observed in 25 of 35 cases (71%) using conventional histology and in 30 of 32 cases (94%) using immunohistochemistry, was correlated with portal and lobular inflammation, interface hepatitis and centrilobular necrosis as well as bile duct injury and fibrosis. In 11 of 14 cases (79%) ductular reaction remained present on post-treatment biopsy whereas bile duct injury persisted in six of 14 (43%) of cases. Bile duct injury and ductular reaction are very common in newly diagnosed autoimmune hepatitis and cannot be predicted biochemically. Bile duct injury may subside in the majority of treated AIH cases while DR tends to persist during follow up. These findings show that the two phenomena are part of the spectrum of AIH with dissimilar responses to treatment and do not necessarily point towards an overlap syndrome. Persistence of ductular reaction after treatment supports the notion that it represents a regenerative response. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Patients with autoimmune polyendocrine syndrome type 1 (APS-1) suffer from multiple organ-specific autoimmunity with autoantibodies against target tissue-specific autoantigens. Endocrine and nonendocrine organs such as skin, hair follicles, and liver are targeted by the immune system. Despite sporadic observations of pulmonary symptoms among APS-1 patients, an autoimmune mechanism for pulmonary involvement has not been elucidated. We report here on a subset of APS-1 patients with respiratory symptoms. Eight patients with pulmonary involvement were identified. Severe airway obstruction was found in 4 patients, leading to death in 2. Immunoscreening of a cDNA library using serum samples from a patient with APS-1 and obstructive respiratory symptoms identified a putative potassium channel regulator (KCNRG) as a pulmonary autoantigen. Reactivity to recombinant KCNRG was assessed in 110 APS-1 patients by using immunoprecipitation. Autoantibodies to KCNRG were present in 7 of the 8 patients with respiratory symptoms, but in only 1 of 102 APS-1 patients without respiratory symptoms. Expression of KCNRG messenger RNA and protein was found to be predominantly restricted to the epithelial cells of terminal bronchioles. Autoantibodies to KCNRG, a protein mainly expressed in bronchial epithelium, are strongly associated with pulmonary involvement in APS-1. These findings may facilitate the recognition, diagnosis, characterization, and understanding of the pulmonary manifestations of APS-1.

To our knowledge the coexistence between Sweet's Syndrome and hypertrophic cranial pachymeningitis has not been reported up to date. We suggest a possible autoimmune or dysimmune mechanism in the pathogenesis of these two entities

Abstract Autoimmune gastritis is often suspected for its hematologic findings, and rarely the diagnosis is made for the presence of gastrointestinal symptoms. Aims of this cross-sectional study were to assess in a large cohort of patients affected by autoimmune gastritis the occurrence and the pattern of gastrointestinal symptoms and to evaluate whether symptomatic patients are characterized by specific clinical features. Gastrointestinal symptoms of 379 consecutive autoimmune gastritis patients were systematically assessed and classified following Rome III Criteria. Association between symptoms and anemia pattern, positivity to gastric autoantibodies, Helicobacter pylori infection, and concomitant autoimmune disease were evaluated. In total, 70.2% of patients were female, median age 55 years (range 17–83). Pernicious anemia (53.6%), iron deficiency anemia (34.8%), gastric autoantibodies (68.8%), and autoimmune disorders (41.7%) were present. However, 56.7% of patients complained of gastrointestinal symptoms, 69.8% of them had exclusively upper symptoms, 15.8% only lower and 14.4% concomitant upper and lower symptoms. Dyspepsia, subtype postprandial distress syndrome was the most represented, being present in 60.2% of symptomatic patients. Univariate and multivariate analyses showed that age gastritis is associated in almost 60% of cases with gastrointestinal symptoms, in particular dyspepsia. Dyspepsia is strictly related to younger age, no smoking, and absence of anemia. PMID:28072728

Primary Sjogren’s Syndrome Associated With Treatment-Resistant Obsessive–Compulsive Disorder

Full Text Available There is an increasing awareness that autoimmune diseases can present with neuropsychiatric manifestations. We present the case of a 17-year-old female requiring psychiatric hospitalization for obsessive–compulsive disorder and major depressive disorder with mixed affective features, who was subsequently diagnosed with primary Sjogren’s syndrome. Treatment with potent immunosuppression resulted in remission of psychiatric illness. Due to a lack of awareness and/or the lack of specific biomarkers, clinicians may not associate psychiatric symptoms with autoimmune disease, including primary Sjogren’s syndrome. This case demonstrates that Sjogren’s syndrome may be a causative or aggravating factor in mental disorders and that autoimmune diseases should be carefully considered in the differential diagnosis of psychiatric illness especially in cases of concurrent physical symptomatology and severity or treatment resistance of psychiatric disease.

The immunosuppresive drugs, primarily glucocorticosteroids, serve as the basis for the pathogenetic treatment of autoimmune diseases of the liver. In autoimmune hepatitis, immunosuppressive therapy induces and maintains persistent remission in most patients while in primary biliary cirrhosis and primary sclerosing cholangitis, its capacities are substantially limited. Ursodeoxycholic acid is used as the basic drug in predominantly occurring intrahepatic cholestasis. The treatment of cross autoimmune syndromes generally requires the choice of a combination of drugs.

Wernicke-Korsakoff syndrome (also called Wernicke's encephalopathy) is a potentially fatal, neuropsychiatric syndrome caused most frequently by thiamine deficiency. The three classic symptoms found together are confusion, ataxia and eyeball manifestations. Memory disturbances can also be symptoms. Wernicke's encephalopathy mainly results from alcohol abuse, but also from malnutrition, cancer, chronic dialysis, thyrotoxicosis and, in well-founded cases, encephalopathy associated with autoimmune thyroid disease (EAATD). The coexistence of many factors makes a proper diagnosis difficult, delays appropriate treatment and consequently reduces the chance of complete recovery. We present the case of a 53 year-old female with Wernicke's encephalopathy caused by chronic malnutrition, surgical operation, as well as thyrotoxicosis. She received treatment with intravenous thiamine administration and also anti-thyroid treatment which caused satisfactory regression of her neurological symptoms.

Overlap of autoimmune hepatitis and systemic lupus erythematosus (SLE) is a comparatively rare condition. Although both autoimmune hepatitis and SLE can share common autoimmune features such as polyarthralgia, hypergammaglobulinemia and positive ANA, it has been considered as two different entities. We report a case of anti-LKM1 positive autoimmune hepatitis who developed SLE two years later. The presence of interface hepatitis with lymphoplasma cell infiltrates and rosette formation points to the autoimmune hepatitis rather than SLE hepatitis. Autoimmune hepatitis is infrequently accompanied by SLE, therefore, it could be recommended to investigate for SLE in patients with autoimmune hepatitis.

The localized scleroderma (LS) known as morphea, presents a variety of clinical manifestations that can include systemic involvement. Current classification schemes divide morphea into categories based solely on cutaneous morphology, without reference to systemic disease or autoimmune phenomena. This classification is likely incomplete. Autoimmune phenomena such as vitiligo and Hashimoto thyroiditis associated with LS have been reported in some cases suggesting an autoimmune basis.

2011-01-01

Full Text Available Antiphospholipid syndrome is a systemic autoimmune disease with thrombotic tendency. Consensus guidelines for pregnancy with antiphospholipid syndrome recommend low-dose aspirin combined with unfractionated or low-molecular-weight heparin because antiphospholipid syndrome causes habitual abortion. We report a 36-year-old pregnant woman diagnosed with antiphospholipid syndrome receiving anticoagulation treatment. The patient developed left abdominal pain and gross hematuria at week 20 of pregnancy. An initial diagnosis of left ureteral calculus was made. Subsequently abdominal-pelvic computed tomography was required for diagnosis because of the appearance of severe contralateral pain. Computed tomography revealed serious renal hemorrhage, and ureteral stent placement and pain control by patient-controlled analgesia were required. After treatment, continuance of pregnancy was possible and vaginal delivery was performed safely. This is the first case report of serious renal hemorrhage in a pregnant woman with antiphospholipid syndrome receiving anticoagulation treatment and is an instructive case for urological and obstetrical practitioners.

Antiphospholipid syndrome is revealed by Budd Chiari syndrome in 5% of the cases. Antiphospholipid syndrome is characterized by venous or arterial thrombosis, foetal loss and positivity of antiphospholipid antibodies, namely lupus anticoagulant, anticardiolipin antibodies and anti-beta2-glycoprotein I. Anticardiolipin antibodies was reported in auto-immune thyroid disorders, particularly in Grave's disease. Antiphospholipid syndrome associated to Grave's disease was reported in only three cases. To describe a case report of association of Grave's disease and antiphospholipid syndrome. We report the first case of Grave's disease associated with antiphospholipid syndrome, revealed by Budd Chiari syndrome. Our observation is particular by the fact that it is about a patient presenting a Grave's disease associated with antiphospholipid syndrome revealed by Budd Chiari syndrome. This triple association has never been reported in literature. Although association between antiphospholipid syndrome and Grave's disease was previously described, further studies evaluating the coexistence of these two affections in the same patient would be useful.

The patient, a 24-year-old man, had suffered from hunger, sweating, tachycardia and palpitation for three years. He was diagnosed as having Graves' disease (GD) and treated with methimazole (MMI) for 3 months. He noted that palpitation and perspiration seemed to particularly occur when he was hungry, and thus he was examined to determine whether these symptoms were caused by hypoglycemia. As a markedly elevated immunoreactive insulin level and the presence of insulin antibody in serum were found, he was diagnosed as having insulin autoimmune syndrome (IAS). HLA typing revealed the patient to be positive for group Bw62/Cw4/DR4, which is reportedly a specific HLA type in MMI-treated euthyoroid GD patients with IAS. In spite of the continuation of MMI treatment, the % binding of IRI decreased and the hypoglycemic episode disappeared. In contrast to the previously reported MMI induced IAS in GD cases, MMI is unlikely to have exacerbated IAS in the present case, although his HLA combination is identical to that of the previous cases.

Endocrine autoimmune disease: genetics become complex.

The endocrine system is a frequent target in pathogenic autoimmune responses. Type 1 diabetes and autoimmune thyroid disease are the prevailing examples. When several diseases cluster together in one individual, the phenomenon is called autoimmune polyglandular syndrome. Progress has been made in understanding the genetic factors involved in endocrine autoimmune diseases. Studies on monogenic autoimmune diseases such as autoimmune polyglandular syndrome type 1, immunodysregulation, polyendocrinopathy, enteropathy, X-linked and primary immune deficiencies helped uncover the role of key regulators in the preservation of immune tolerance. Alleles of the major histocompatibility complex have been known to contribute to the susceptibility to most forms of autoimmunity for more than 3 decades. Furthermore, sequencing studies revealed three non-major histocompatibility complex loci and some disease specific loci, which control T lymphocyte activation or signalling. Recent genome-wide association studies (GWAS) have enabled acceleration in the identification of novel (non-HLA) loci and hence other relevant immune response pathways. Interestingly, several loci are shared between autoimmune diseases, and surprisingly some work in opposite direction. This means that the same allele which predisposes to a certain autoimmune disease can be protective in another. Well powered GWAS in type 1 diabetes has led to the uncovering of a significant number of risk variants with modest effect. These studies showed that the innate immune system may also play a role in addition to the adaptive immune system. It is anticipated that next generation sequencing techniques will uncover other (rare) variants. For other autoimmune disease (such as autoimmune thyroid disease) GWAS are clearly needed. © 2010 The Authors.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is accompanied by activation of immuno-inflammatory pathways, increased bacterial translocation and autoimmune responses to serotonin (5-HT). Inflammation is known to damage 5-HT neurons while bacterial translocation may drive autoimmune responses. This study has been carried out to examine the autoimmune responses to 5-HT in ME/CFS in relation to inflammation and bacterial translocation. We examined 5-HT antibodies in 117 patients with ME/CFS (diagnosed according to the centers for disease control and prevention criteria, CDC) as compared with 43 patients suffering from chronic fatigue (CF) but not fulfilling the CDC criteria and 35 normal controls. Plasma interleukin-1 (IL-1), tumor necrosis factor (TNF)α, neopterin and the IgA responses to Gram-negative bacteria were measured. Severity of physio-somatic symptoms was measured using the fibromyalgia and chronic fatigue syndrome rating scale (FF scale). The incidence of positive autoimmune activity against 5-HT was significantly higher (pfatigue, neurocognitive and autonomic symptoms, sadness and a flu-like malaise. The results show that, in ME/CFS, increased 5-HT autoimmune activity is associated with activation of immuno-inflammatory pathways and increased bacterial translocation, factors which are known to play a role in the onset of autoimmune reactions. 5-HT autoimmune activity could play a role in the pathophysiology of ME/CFS and the onset of physio-somatic symptoms. These results provide mechanistic support for the notion that ME/CFS is a neuro-immune disorder. Copyright © 2013 Elsevier B.V. All rights reserved.

Occurrence of Autoimmune Diseases Related to the Vaccine against Yellow Fever

Ana Cristina Vanderley Oliveira

2014-01-01

Full Text Available Yellow fever is an infectious disease, endemic in South America and Africa. This is a potentially serious illness, with lethality between 5 and 40% of cases. The most effective preventive vaccine is constituted by the attenuated virus strain 17D, developed in 1937. It is considered safe and effective, conferring protection in more than 90% in 10 years. Adverse effects are known as mild reactions (allergies, transaminases transient elevation, fever, headache and severe (visceral and neurotropic disease related to vaccine. However, little is known about its potential to induce autoimmune responses. This systematic review aims to identify the occurrence of autoinflammatory diseases related to 17D vaccine administration. Six studies were identified describing 13 possible cases. The diseases were Guillain-Barré syndrome, multiple sclerosis, multiple points evanescent syndrome, acute disseminated encephalomyelitis, autoimmune hepatitis, and Kawasaki disease. The data suggest that 17D vaccination may play a role in the mechanism of loss of self-tolerance.

A case of autoimmune polyglandular syndrome (APS) is presented. A 45-year-old man was admitted due to fatigue, malaise and inappetence. He had a history of primary hypothyroidism and was on levothyroxine substitution therapy. One year before, he was diagnosed with normocytic anemia and vitamin B12 deficiency, which was treated with vitamin B12 substitution therapy. Physical examination revealed hypotension and marked hyperpigmentation. Laboratory testing showed hyponatremia, hyperkaliemia and severe normocytic anemia. Endocrinological evaluation disclosed low morning cortisol and increased adrenocorticotropic hormone levels. Hence, the diagnosis of Addison's disease was established. Additional laboratory workup showed positive parietal cell antibodies. However, his vitamin B12 levels were increased due to vitamin B12 supplementation therapy, which was initiated earlier. Gastroscopy and histopathology of gastric mucosa confirmed atrophic gastritis. Based on prior low serum vitamin B12 levels, positive parietal cell antibodies and atrophic gastritis, the patient was diagnosed with pernicious anemia. Hydrocortisone supplementation therapy was administered and titrated according to urinary-free cortisol levels. Electrolyte disbalance and red blood cell count were normalized. This case report demonstrates rather unique features of pernicious anemia in a patient with Addison's disease. It also highlights the link between type II and type III APS. Not only do they share the same etiological factors, but also overlap in pathophysiological and clinical characteristics. This case report favors older classification of APS, which consolidates all endocrine and other organ-specific autoimmune diseases into one category. This is important since it might help avoid pitfalls in the diagnosis and treatment of patients with APS.

The uveal tract represents the vascular organ of the eye. In addition to providing most of the blood supply to the intraocular structures, it acts as a conduit for immune cells, particularly lymphocytes, to enter the eye. Consequently, the uveal tract is represented in many intraocular inflammatory processes. Uveitis is probably a misnomer unless antigens within the uvea are the direct targets of the inflammatory process. A better term of the condition is "intraocular inflammation" (IOI). To review the presence of IOI in autoimmune diseases, the immunopathogenic mechanisms leading to disease, and treatment. We reviewed the English medical literature by using MEDLINE (1984-2003) employing the terms "uveitis," "intraocular inflammation," and "autoimmune diseases." An underlying autoimmune disease was identified in up to 40% of patients with IOI, and included spondyloarthropathies, Behcets disease, sarcoidosis, juvenile chronic arthritis, Vogt-Koyanagi-Harada syndrome (an inflammatory syndrome including uveitis with dermatologic and neurologic manifestations), immune recovery syndrome, and uveitis with tubulointerstitial disease. The immunopathogenesis of IOI involves enhanced T-cell response. Recently, guidelines for the use of immunosuppressive drugs for inflammatory eye disease were established and include: corticosteroids, azathioprine, methotrexate, mycophenolate mofetil, cyclosporine, tacrolimus, cyclophosphamide, and chlorambucil. New therapies with limited experience include the tumor necrosis factor alpha inhibitors, interferon alfa, monoclonal antibodies against lymphocyte surface antigens, intravenous immunoglobulin (IVIG), and the intraocular delivery of immunosuppressive agents. An underlying autoimmune disease was identified in up to 40% of patients with IOI. Immunosuppressive drugs, biologic agents, and IVIG are employed for the treatment of IOI in autoimmune diseases.

Predicting post-vaccination autoimmunity: who might be at risk?

Vaccinations have been used as an essential tool in the fight against infectious diseases, and succeeded in improving public health. However, adverse effects, including autoimmune conditions may occur following vaccinations (autoimmune/inflammatory syndrome induced by adjuvants--ASIA syndrome). It has been postulated that autoimmunity could be triggered or enhanced by the vaccine immunogen contents, as well as by adjuvants, which are used to increase the immune reaction to the immunogen. Fortunately, vaccination-related ASIA is uncommon. Yet, by defining individuals at risk we may further limit the number of individuals developing post-vaccination ASIA. In this perspective we defined four groups of individuals who might be susceptible to develop vaccination-induced ASIA: patients with prior post-vaccination autoimmune phenomena, patients with a medical history of autoimmunity, patients with a history of allergic reactions, and individuals who are prone to develop autoimmunity (having a family history of autoimmune diseases; asymptomatic carriers of autoantibodies; carrying certain genetic profiles, etc.).

We report a 37-year-old woman with a 2 month history of proximal muscle weakness and extremely high creatine kinase (21,808 U/L) due to necrotizing auto-immune myositis (NAM) in association with anti-synthetase syndrome. Myositis-specific auto-immune antibody panel was positive for anti-Signal recognition particle and anti-PL-12. CT scan of the chest confirmed interstitial lung disease. Prednisolone, intravenous immunoglobulin and cyclophosphamide therapy was given with gradual improvement. This patient is notable for the unusual combination of NAM and anti-synthetase syndrome with the rare finding of two myositis-specific autoantibodies, which directed testing for associated extramuscular features and management with more aggressive immunotherapy.

Update in endocrine autoimmunity.

The endocrine system is a common target in pathogenic autoimmune responses, and there has been recent progress in our understanding, diagnosis, and treatment of autoimmune endocrine diseases. Rapid progress has recently been made in our understanding of the genetic factors involved in endocrine autoimmune diseases. Studies on monogenic autoimmune diseases that include endocrine phenotypes like autoimmune polyglandular syndrome type 1 and immune dysregulation, polyendocrinopathy, enteropathy, X-linked have helped reveal the role of key regulators in the maintenance of immune tolerance. Highly powered genetic studies have found and confirmed many new genes outside of the established role of the human leukocyte antigen locus with these diseases, and indicate an essential role of immune response pathways in these diseases. Progress has also been made in identifying new autoantigens and the development of new animal models for the study of endocrine autoimmunity. Finally, although hormone replacement therapy is still likely to be a mainstay of treatment in these disorders, there are new agents being tested for potentially treating and reversing the underlying autoimmune process. Although autoimmune endocrine disorders are complex in etiology, these recent advances should help contribute to improved outcomes for patients with, or at risk for, these disorders.

New splice site acceptor mutation in AIRE gene in autoimmune polyendocrine syndrome type 1.

Directory of Open Access Journals (Sweden)

Mireia Mora

Full Text Available Autoimmune polyglandular syndrome type 1 (APS-1, OMIM 240300 is a rare autosomal recessive disorder, characterized by the presence of at least two of three major diseases: hypoparathyroidism, Addison's disease, and chronic mucocutaneous candidiasis. We aim to identify the molecular defects and investigate the clinical and mutational characteristics in an index case and other members of a consanguineous family. We identified a novel homozygous mutation in the splice site acceptor (SSA of intron 5 (c.653-1G>A in two siblings with different clinical outcomes of APS-1. Coding DNA sequencing revealed that this AIRE mutation potentially compromised the recognition of the constitutive SSA of intron 5, splicing upstream onto a nearby cryptic SSA in intron 5. Surprisingly, the use of an alternative SSA entails the uncovering of a cryptic donor splice site in exon 5. This new transcript generates a truncated protein (p.A214fs67X containing the first 213 amino acids and followed by 68 aberrant amino acids. The mutation affects the proper splicing, not only at the acceptor but also at the donor splice site, highlighting the complexity of recognizing suitable splicing sites and the importance of sequencing the intron-exon junctions for a more precise molecular diagnosis and correct genetic counseling. As both siblings were carrying the same mutation but exhibited a different APS-1 onset, and one of the brothers was not clinically diagnosed, our finding highlights the possibility to suspect mutations in the AIRE gene in cases of childhood chronic candidiasis and/or hypoparathyroidism otherwise unexplained, especially when the phenotype is associated with other autoimmune diseases.

Context: Autoimmune polyendocrine syndrome type 1 (APS1) is a childhood-onset monogenic disease defined by the presence of two of the three major components: hypoparathyroidism, primary adrenocortical insufficiency, and chronic mucocutaneous candidiasis (CMC). Information on longitudinal follow-up of APS1 is sparse. Objective: To describe the phenotypes of APS1 and correlate the clinical features with autoantibody profiles and autoimmune regulator (AIRE) mutations during extended follow-up (1996–2016). Patients: All known Norwegian patients with APS1. Results: Fifty-two patients from 34 families were identified. The majority presented with one of the major disease components during childhood. Enamel hypoplasia, hypoparathyroidism, and CMC were the most frequent components. With age, most patients presented three to five disease manifestations, although some had milder phenotypes diagnosed in adulthood. Fifteen of the patients died during follow-up (median age at death, 34 years) or were deceased siblings with a high probability of undisclosed APS1. All except three had interferon-ω) autoantibodies, and all had organ-specific autoantibodies. The most common AIRE mutation was c.967_979del13, found in homozygosity in 15 patients. A mild phenotype was associated with the splice mutation c.879+1G>A. Primary adrenocortical insufficiency and type 1 diabetes were associated with protective human leucocyte antigen genotypes. Conclusions: Multiple presumable autoimmune manifestations, in particular hypoparathyroidism, CMC, and enamel hypoplasia, should prompt further diagnostic workup using autoantibody analyses (eg, interferon-ω) and AIRE sequencing to reveal APS1, even in adults. Treatment is complicated, and mortality is high. Structured follow-up should be performed in a specialized center. PMID:27253668

Autoimmune liver disease (ALD) includes a spectrum of diseases which comprises both cholestatic and hepatitic forms: autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC) and the so called "overlap" syndromes where hepatitic and cholestatic damage coexists. All these diseases are characterized by an extremely high heterogeneity of presentation, varying from asymptomatic, acute (as in a subset of AIH) or chronic (with aspecific symptoms such as fatigue and myalgia in AIH or fatigue and pruritus in PBC and PSC). The detection and characterization of non organ specific autoantibodies plays a major role in the diagnostic approach of autoimmune liver disease; anti nuclear reactivities (ANA) and anti smooth muscle antibodies (SMA) mark type 1 AIH, liver kidney microsomal antibody type 1 (LKM1) and liver cytosol type 1 (LC1) are the serological markers of type 2 AIH; antimitochondrial antibodies (AMA) are associated with PBC, while no specific marker is found in PSC, since anticytoplasmic neutrophil antibodies with perinuclear pattern (atypical p-ANCA or p-ANNA) are also detected in a substantial proportion of type 1 AIH cases. Treatment options rely on immunosoppressive therapy (steroids and azathioprine) in AIH and on ursodeoxycholic acid in cholestatic conditions; in all these diseases liver transplantation remains the only therapeutical approach for the end stage of liver disease.

Autoimmune lymphoproliferative syndrome (ALPS) usually presents in childhood with fever, nonmalignant splenomegaly and lymphadenopathy along with hemocytopenia. This case report describes a 10-year-old boy presenting with signs of autoimmune disease, splenomegaly, hepatomegaly and resistant hemocytopenia. Sirolimus controlled the relapsed thrombocytopenia after splenectomy. Sequencing of the FAS gene identified two spontaneous heterozygous mutations (c.234 T > G, p.D78E) (c.236dupA, p.P80Tfs*26). The boy's homozygous missense variation (c.2588G > A, p.G863D) (rs140184929) in UNC13D gene had been identified as being related to familial hemophagocytic lymphohistiocytosis (FHL). TCRαβ + CD4/CD8 double-negative T cells (markers of ALPS) were not significantly increased from the outset. Elevated cytokines, such as interferon (IFN)-γ, interleukin (IL)-6 and tumor necrosis factor α decreased to normal levels after splenectomy whereas IL-10 remained high. Immunological analysis of the patient revealed a marked depletion of forkhead-box P3 + expressing regulatory T cells (Treg) and Th17 cells. The obtained data demonstrate that mutations to FAS and UNC13D which result in overwhelming T-cell and macrophage activation, one associated with inhibited Treg cell development and a severe ALPS-like symptom. Therefore, we propose that variations of UND13D may be a risk factor of ALPS development. Copyright © 2017. Published by Elsevier B.V.

Cutting Edge: cGAS Is Required for Lethal Autoimmune Disease in the Trex1-Deficient Mouse Model of Aicardi-Goutières Syndrome.

Gray, Elizabeth E; Treuting, Piper M; Woodward, Joshua J; Stetson, Daniel B

2015-09-01

Detection of intracellular DNA triggers activation of the stimulator of IFN genes-dependent IFN-stimulatory DNA (ISD) pathway, which is essential for antiviral immune responses. However, chronic activation of this pathway is implicated in autoimmunity. Mutations in TREX1, a 3' repair exonuclease that degrades cytosolic DNA, cause Aicardi-Goutières syndrome and chilblain lupus. Trex1 (-/-) mice develop lethal, IFN-driven autoimmune disease that is dependent on activation of the ISD pathway, but the DNA sensors that detect the endogenous DNA that accumulates in Trex1 (-/-) mice have not been defined. Multiple DNA sensors have been proposed to activate the ISD pathway, including cyclic GMP-AMP synthase (cGAS). In this study, we show that Trex1 (-/-) mice lacking cGAS are completely protected from lethality, exhibit dramatically reduced tissue inflammation, and fail to develop autoantibodies. These findings implicate cGAS as a key driver of autoimmune disease and suggest that cGAS inhibitors may be useful therapeutics for Aicardi-Goutières syndrome and related autoimmune diseases.

A case of hypertrophic cranial pachymeningitis associated with Sweet's Syndrome is presented. Both entities have been described in association with several other chronic systemic inflammatory diseases and autoimmune conditions. To our knowledge the coexistence between Sweet's Syndrome and hypertrophic cranial pachymeningitis has not been reported up to date. We suggest a possible autoimmune or dysimmune mechanism in the pathogenesis of these two entities.

Full Text Available Sheehan’s syndrome remains a frequent obstetric complication with an uncertain pathophysiology. We aimed to assess the incidence of hypopituitarism (≥2 hormonal axis impairment within the first six postchildbirth months and to determine the existence of anti-pituitary antibodies. From 2015 to 2017, adult pregnant women, who developed moderate to severe postpartum hemorrhage (PPH, were consecutively included in the study. Pituitary function was assessed 4 and 24 weeks after PPH. At the end of the study, anti-pituitary antibodies were assessed. Twenty women completed the study. Mean age was 26.35 (±5.83 years. The main etiology for severe PPH was uterine atony (65% which resulted mostly in hypovolemic shock grades III-IV. Within the first four weeks after delivery, 95% of patients had at least one hormonal pituitary affected and 60% of the patients fulfilled diagnostic criteria for hypopituitarism. At the end of the study period, five patients (25% were diagnosed with hypopituitarism (GH and cortisol axes affected. Anti-pituitary antibodies were negative in all patients. At 6 months follow-up, one in every four women with a history of moderate-to-severe PPH was found with asymptomatic nonautoimmune-mediated hypopituitarism. The role of autoimmunity in Sheehan’s syndrome remains uncertain. Further studies are needed to improve the remaining knowledge gaps.

Eosinophils in Autoimmune Diseases

2017-04-01

Full Text Available Eosinophils are multifunctional granulocytes that contribute to initiation and modulation of inflammation. Their role in asthma and parasitic infections has long been recognized. Growing evidence now reveals a role for eosinophils in autoimmune diseases. In this review, we summarize the function of eosinophils in inflammatory bowel diseases, neuromyelitis optica, bullous pemphigoid, autoimmune myocarditis, primary biliary cirrhosis, eosinophilic granulomatosis with polyangiitis, and other autoimmune diseases. Clinical studies, eosinophil-targeted therapies, and experimental models have contributed to our understanding of the regulation and function of eosinophils in these diseases. By examining the role of eosinophils in autoimmune diseases of different organs, we can identify common pathogenic mechanisms. These include degranulation of cytotoxic granule proteins, induction of antibody-dependent cell-mediated cytotoxicity, release of proteases degrading extracellular matrix, immune modulation through cytokines, antigen presentation, and prothrombotic functions. The association of eosinophilic diseases with autoimmune diseases is also examined, showing a possible increase in autoimmune diseases in patients with eosinophilic esophagitis, hypereosinophilic syndrome, and non-allergic asthma. Finally, we summarize key future research needs.

Full Text Available Sjögren syndrome (SS is a chronic, inflammatory, autoimmune disease. It emerges as a dry mouth and eyes (sicca symptoms because, it fundamentally affects exocrine glands, frequently, salivary gland and lachrymal gland. Neurological involvement in Sjögren syndrome is observed in the approximately 20-25% of cases. 87% of the neurological involvements are peripheral nervous system involvement and around 13% of the neurological involvements are central nervous system involvement. Cerebral involvement represents heterogeneous features in terms of both localization (focal or diffuse and progress of the statement (acute, progressive or reversible. Affected central nervous system can show clinical and radiological signs similar to Multiple sclerosis (MS. In this paper, the case, which has a complaint of difficulty in walking and instability and MS like lesions in brain magnetic resonance imaging (MRI and is diagnosed as Sjögren syndrome by further research, is discussed

Autoimmune features caused by dengue fever: a case report

Directory of Open Access Journals (Sweden)

Denis Leonardo Fontes Jardim

Full Text Available Dengue virus is the most important mosquito-borne viral disease in the world. Co-circulation of the four types of dengue viruses and expansion of dengue epidemic gave rise to infection enhancement and a big expansion of clinical aspects of the disease. Herein we report a case of a 25-year-old white woman with dengue fever and numerous associated autoimmune features. Our patient had proteinuria, an extensive right pleural effusion, a thin pericardial effusion and ascites. She had a low C3 level and positive antinuclear antibody; cryoglobulins were also positive. The numerous autoimmune features of this patient were a diagnostic challenge, since she was a young woman and could be easily mistaken for a rheumatologic patient in a newly open disease. Dengue infection probably was a triggering event causing an abnormal immune response. Therefore, dengue should be suspected in patients with hematological disorders and autoimmune features in endemic regions or those who have travelled to those regions.

Full Text Available Monogenic primary immunodeficiency syndromes can affect one or more endocrine organs by autoimmunity during childhood. Clinical manifestations include type1 diabetes mellitus, hypothyroidism, adrenal insufficiency and vitiligo. LPS-responsive beige-like anchor protein (LRBA deficiency was described in 2012 as a novel primary immunodeficiency, predominantly causing immune dysregulation and early onset enteropathy. We describe the heterogeneous clinical course of LRBA deficiency in two siblings, mimicking an autoimmune polyendocrine disorder in one of them in presence of the same underlying genetic mutation. The third child of consanguineous Egyptian parents (Patient 1 presented at six months of age with intractable enteropathy and failure to thrive. Later on he developed symptoms of adrenal insufficiency, autoimmune haemolytic anaemia, thrombocytopenia, and infectious complications due to immunosuppressive treatment. The severe enteropathy was non-responsive to the standard treatment and led to death at the age of 22 years. His younger sister (Patient 2 presented at the age of 12 to the endocrinology department with decompensated hypothyroidism, perioral vitiligo, delayed pubertal development, and growth failure without enteropathy and immunodeficiency.Using whole-exome sequencing (WES we identified a homozygous frameshift mutation (c.6862delT, p.Y2288MfsX29 in the LRBA gene in both siblings. To our knowledge our patient (patient 2 is the first case of LRBA deficiency described with predominant endocrine phenotype without immunodeficiency and enteropathy. LRBA deficiency should be considered as underlying disease in pediatric patients presenting with autoimmune endocrine symptoms. The same genetic mutation can manifest with a broad phenotypic spectrum without genotype-phenotype correlation. The awareness for disease symptoms among non-immunologists might be a key to early diagnosis. Further functional studies in LRBA deficiency are necessary to

Full Text Available Background: Autoimmune pancreatitis is a recently described type of pancreatitis of presumed autoimmune etiology. Autoimmune pancreatitis is often misdiagnosed as pancreatic cancer difficult, since their clinical presentations are often similar. The concept of autoimmune pancreatitis was first published in 1961. Since then, autoimmune pancreatitis has often been treated not as an independent clinical entity but rather as a manifestation of systemic disease. The overall prevalence and incidence of the disease have yet to be determined, but three series have reported the prevalence as between 5 and 6 % of all patients with chronic pancreatitis. Patient vary widely in age, but most are older than 50 years. Patients with autoimmune pancreatitis usually complain of the painless jaundice, mild abdominal pain and weight loss. There is no laboratory hallmark of the disease, even if cholestatic profiles of liver dysfunction with only mild elevation of amylase and lipase levels have been reported.Conclusions: Proposed diagnostic criteria contains: (1 radiologic imaging, diffuse enlargement of the pancreas and diffusely irregular narrowing of the main pancreatic duct, (2 laboratory data, elevated levels of serum ã-globulin and/or IgG, specially IgG4, or the presence of autoantibodies and (3 histopathologic examination, fibrotic change with dense lymphoplasmacytic infiltration in the pancreas. For correct diagnosis of autoimmune pancreatitis, criterion 1 must be present with criterion 2 and/or 3. Autoimmune pancreatitis is frequently associated with rheumatoid arthritis, Sjogren’s syndrome, inflammatory bowel disease, tubulointersticial nephritis, primary sclerosing cholangitis and idiopathic retroperitoneal fibrosis. Pancreatic biopsy using an endoscopic ultrasound-guided fine needle aspiration biopsy is the most important diagnostic method today. Treatment with corticosteroids leads to the and resolution of pancreatic inflamation, obstruction and

Autoimmune thyroiditis associated with neuromyelitis optica (NMO

Sudulagunta, Sreenivasa Rao

2015-11-01

Full Text Available Neuromyelitis optica (NMO or Devic’s syndrome is a rare relapsing demyelinating disease of the central nervous system (CNS that mainly affects the spinal cord and optic nerves and shares many clinical and radiological features with multiple sclerosis. The association of NMO with other autoimmune diseases was reported, but very few reports described association with autoimmune thyroid disease. Early differentiation between NMO and multiple sclerosis is very important as the natural course and treatment regimens differ significantly. We report a case of a 50-year-old woman who was admitted initially with vomiting, hiccups and paraesthesias but was not diagnosed with NMO and presented with a severe progression of the disease. The patient was also diagnosed to have autoimmune thyroiditis with lymphocytic infiltration of the thyroid which progressed from hyperthyroidism to hypothyroidism. NMO diagnosis was established with seropositivity for NMO-IgG and MRI showing longitudinally extensive spinal cord lesions (3 or more spinal segments. In spite of treatment, the response was poor due to lack of early diagnosis and aggressive immunosuppressant therapy.

Autoimmune encephalitis is rare. Several auto- antibodies are described in autoimmune encephalitis. We describe a case of autoimmune limbic encephalitis associated with positive voltage gated potassium channel (VGKC) antibodies and positive leucine-rich glioma inactivated protein 1 antibodies (LGI1). A 33-year-old Saudi housewife, she presented with 2 months history of cognitive deterioration and recurrent left facio-brachial dystonic seizures followed by generalized tonic clonic seizures. At times the seizures are preceded by rising epigastric aura and shortness of breath. The neurological examination was normal apart from upgoing left plantar reflex. She had borderline IQ of 76 with impaired verbal fluency and impaired visual and verbal memory. Magnetic resonance imaging of the brain showed right mesial temporal non-enhancing lesion. Cerebrospinal fluid examination was positive for LGI1 and VGKC. Optimal seizure control was achieved with immunotherapy.

Autoimmune polyglandular syndrome type 3 - (APS-3), is defined as the coexistence of autoimmune thyroiditis with other non-ovarian autoimmune diseases without primary adrenal insufficiency. Additionally the definition of APS-3 also includes primary ovarian insufficiency (POI) coexistence with autoimmune thyroiditis. The main goal of that study is to assess the prevalence of APS-3 defined as coexistence of autoimmune thyroiditis with POI in population of 46 XX karyotype women with primary ovarian insufficiency (POI). The second goal is to investigate hormonal profile and insulin sensitivity in women with POI and subgroups of women with APS-3 - POI/APS-3(+) and without APS 3 - POI/APS-3(-). Anthropometric measurements, coexistence of autoimmune diseases, androgens, fasting glucose and insulin, glucose and insulin at 60' and 120' of oral glucose tolerance test (OGTT) and homeostasis model for insulin resistance (HOMA-IR), were determine in 98 patients aged between 18 and 39 with spontaneous 46 XX primary ovarian insufficiency (POI), in 33 POI/APS-3(+), 65 POI/APS-3(-), and 75 healthy controls. Continuous data were summarized by the mean±standard deviation (SD), and categorical data by number (percentages). Data were checked for normality using Shapiro-Wilk test, the comparison between groups were performed using non-parametric Mann-Whitney or Kruskall-Wallis test. Pearson's correlation coefficient was used to assess the relationships between parameters. Statistical significance was defined as p values APS-3(+) and POI/APS-3(-) showed significantly lower serum androgens in comparison to controls. Additionally women with POI/APS-3(+) showed hyperinsulinemia after 1h of OGTT; No significant differences in serum fasting glucose, insulin and during 2h OGTT between groups were observed. The prevalence of APS-3 is 33.7% in patients with spontaneous 46 XX primary ovarian insufficiency. Women with POI, POI/APS-3(+) and POI/APS-3(-) feature lower testosterone, androstendione

2008-12-01

Previous reports have given evidence that in tropical spastic paraparesis (TSP)/human T-lymphotrophic virus (HTLV-I)-associated myelopathy (HAM), an autoimmune process occurs as part of its pathogenesis. The roles of autoimmunity and the molecular mimicry was evaluated in TSP/HAM patients. Plasma samples were characterized from patients in the Pacific coastal region of Colombia. Thirty-seven were identified as TSP/HAM, 10 were diagnosed with adult T-cell leukemia virus, 22 were asymptomatic carriers but seropositive for HTLV-I and 20 were seronegative and served as negative controls. Plasmatic levels of the following were determined: antinuclear antibody (ANA) levels, anticardiolipine-2 (ACL-2), interferon- (IFN-gamma) and interleukin-4 (IL-4). Using Western blot, the crossreactivity of the seropositive and seronegative samples was evaluated against proteins extracted from several central nervous system components of non infected Wistar rats. The HTLV-I seropositive plasmas were crossreacted with a monoclonal tax (LT4 anti-taxp40) from spinal cord neurons of non infected Wistar rats. Of the TSP/HAM patients, 70.2% were reactive against ANA and 83.8% against ACL-2, in contrast with those ATL and asymptomatic seropositives subjects that were not reactive (P<0.001). Moreover, 70.3% had detectable levels of IFN and 43.2% had detectable IL-4. LT4 anti-taxp40 and plasma of TSP/HAM exhibited cross reactivity with a MW 33-35 kDa protein from the rat spinal cord nuclei. Support was provided for the existence of an autoimmune syndrome mediated by molecular mimicry; the syndrome was responsible for some of the axonal degeneration observed in TSP/HAM patients.

The authors present a case report of a patient, in whom after a head injury the monolateral blindness occurred. Because of autoimmune thrombocytopeny the patient was treated with long-term corticosteroids. The clinical findings corresponded with the orbital apex syndrome. According to the results of the CT and MRI examinations, the sphenoidotomy was indicated, and the histological findings verified fragments of paranasal sinuses' aspergiloma. During the next course of the disease, despite antimycotic therapy, the progression of the aspergiloma in to the anterior cranial fossa occurred. Invasive sino-orbital aspergilosis, after the penetration of the infectious agent across the wall of the sinus, may cause the orbital apex syndrome with paralysis of all three cranial nerves innervating the extraocular muscles, sensoric defect in the area of the ophthalmic nerve and the involvement of the optic nerve.

The Symptoms Get Worse after Pregnancy in Sheehan's Syndrome: A Case Report

Jingwen Hao

2012-01-01

Full Text Available Sheehan’s syndrome, which is pituitary necrosis after severe postpartum hemorrhage and hypovolemia, may cause hypopituitarism immediately or several years later, depending on the degree of tissue destruction. We report an unusual case, in which a 55-year-old woman with Sheehan's syndrome got worse symptoms after spontaneous labor. In 1998, she had severe postpartum hemorrhage and pituitary necrosis during the third delivery, thus it was diagnosed as Sheehan’s syndrome by clinical manifestations, laboratory tests, and magnetic resonance imaging. She was treated by replacement therapy including hydrocortisone and levothyroxine sodium. However, she had the fourth spontaneous pregnancy in 2000 and got worse symptoms after delivery. We carefully concluded that pregnancy provided no evidence against the diagnosis of Sheehan’s syndrome because pregnancy might improve hypopituitarism by stimulating the pituitary remnant to undergo hyperplasia and irritating the placenta to secrete hormone. However, pregnancy might aggravate the symptoms by inducing autoimmunity as well. All in all, early diagnosis and adequate medical treatment are important to provide a good prognosis of Sheehan’s syndrome.

Carlos Isasi

2014-12-01

Full Text Available Introduction, objective: To present a case report in which the finding of non-coeliac gluten sensitivity was decisive for the treatment of a complex autoimmune disease. Materials and methods: A 43-year-old woman with polyarthritis, psoriatic features, anti-SSA/Ro and anti-cyclic citrullinated peptide antibodies, with refractory course, was evaluated for gluten sensitivity despite negative serology for coeliac disease. Results: The patient carried the HLA DQ2 haplotype and duodenal biopsy showed lymphocytic enteritis. A gluten-free diet resolved the clinical picture and permitted tapering of immunosuppressive therapy. Conclusion: Non-coeliac gluten sensitivity can be associated with autoimmunity despite the absence of the specific autoantibodies of coeliac disease.

Environmental chemicals and autoimmune disease: cause and effect

Many important clues have been provided by the relationship of certain medications to lupus and other autoimmune syndromes. These are temporary conditions that resolve when the medication is removed. There are now over 70 such medications which have been reported related to these autoimmune conditions. Interest continues to grow in the potential for environmental substances to cause these syndromes. Among those under suspicion are hydrazines, tartrazines, hair dyes, trichloroethylene, industrial emissions and hazardous wastes. Other possible associations include silica, mercury, cadmium, gold and L canavanine. Two recognised outbreaks include 'toxic oil syndrome' related to contaminated rape seed oil in Spain in 1981 and exposure to a contaminated environmental substance associated with an autoimmune attack on muscle tissue in 1989. Recently, there have been proposals made for the definition and identification of environmentally associated immune disorders. The World Health Organisation (WHO) has also provided recent publications for other environmentally related problems. All these aspects will be presented and reviewed in detail

Type 1 diabetes mellitus (T1D) is an organ-specific autoimmune disease characterized by T-cell mediated self-destruction of insulin-producing β cells in the pancreas. T1D patients are prone to develop other glandular autoimmune disorders, such as autoimmune thyroid disease that occurs simultaneously with autoimmune polyglandular syndrome type III (APSIII). Signal transducer and activator of transcription 4 (STAT4) is a well-known regulator of proinflammatory cytokines, and interferon-induced with helicase C domain 1 (IFIH1) is activated in the interferon type I response. Both genes have been examined separately in autoimmune diseases and, in this study, we assessed their joint role in T1D and APSIII. We conducted a case-control study, enrolling 173 T1D patients and 191 healthy controls from northeastern Brazil, to assess the distribution of the rs7574865 and rs3024839 SNPs in STAT4 and the rs3747517 and rs1990760 SNPs in IFIH1 in T1D and APSIII patients. Additionally, we conducted a meta-analysis with the rs7574865 SNP in STAT4 (1392 T1D patients and 1629 controls) and the rs1990760 SNP in IFIH1 (25092 T1D patients and 28544 controls) to examine their association with T1D. Distribution of STAT4 and IFIH1 allelic frequencies did not show statistically significant differences between T1D patients and controls in our study population; however, the meta-analysis indicated that SNPs in STAT4 and IFIH1 are associated with T1D worldwide. Our findings indicate that although STAT4 and IFIH1 SNPs are not associated with T1D in a Brazilian population, they might play a role in susceptibility to T1D on a larger worldwide scale.

A Case of Devic’s Syndrome Presenting with Tonic Spasm: Response to Levetiracetam Treatment

Alev Leventoğlu

2011-03-01

Full Text Available Neuromyelitis optica or Devic’s syndrome is a rare autoimmune disorder which is characterized by inflammatory demyelination of the optic nerves and the spinal cord. Clinically, it causes visual loss in one or both eyes, and numbness or paralysis of the arms and legs. Although tonic spasm is the most frequent movement disorder occuring in MS, it has not been definetely described clinical entity for Devic’s syndrome. We hereby describe a case of Devic’s syndrome with tonic spasms treated with levetiracetam as a new approach and discussed the results of the treatment. A 52-year-old woman with Devic’s syndrome with the complaint of painful tonic spasms primarily affecting the abdomen was given levetiracetam therapy. Levetiracetam therapy resulted in a good response in our patient. Levetiracetam can be a new choice for the treatment of painful tonic spasm with Devic’s syndrome. However, more detailed studies are necessary to investigate efficacy of levetiracetam.

Pneumocystis jirovecii pneumonia in systemic autoimmune rheumatic disease: A case-control study.

Tadros, Susan; Teichtahl, Andrew J; Ciciriello, Sabina; Wicks, Ian P

2017-06-01

Pneumocystis jirovecii pneumonia (PJP) is an opportunistic fungal infection that affects the immunocompromised. Patients with systemic autoimmune rheumatic disease are increasingly recognised as an at-risk clinical population with a high mortality. This case-control study examined differences in the characteristics and peripheral blood parameters between patients with systemic autoimmune rheumatic disease who developed PJP and gender, age and disease-matched controls. Historical data collected between 2002 and 2013 at the Royal Melbourne Hospital, Australia were reviewed. Cases were defined by having a systemic autoimmune rheumatic disease and a diagnosis of PJP (either a positive toluidine blue O stain or P. jirovecii PCR, with a concurrent respiratory illness that was clinically consistent with PJP). Controls were matched for age, gender and disease in a 4:1 ratio. Peripheral blood results were retrieved from an in-house pathology database. Clinical information including glucocorticoid exposure, PJP prophylaxis, comorbidities and month of admission were retrieved from medical notes. After adjustment for corticosteroid exposure and C-reactive protein, lymphocyte count on admission (0.4 vs. 1.3; p = 0.04) and at nadir (0.2 vs. 0.8 × 10 9 /L; p = 0.05) was significantly lower in cases than in controls. Cases (n = 11) were more frequently Caucasian rather than non-Caucasian (81.8% vs. 65.9%; p = 0.04). In addition, cases more commonly presented in autumn (March to May) than in other seasons (OR = 7.3; 95% CI: 1.4-38.7; p = 0.02). These data demonstrate that patients with systemic autoimmune rheumatic disease who develop PJP have significantly greater lymphopenia than age, gender and disease-matched controls, independent of corticosteroid exposure, as well as a potential ethnicity and seasonal predilection to PJP. This may help to inform prophylactic guidelines for PJP in these patients. Copyright © 2017 Elsevier Inc. All rights reserved.

Volkman, Thomas; Hemingway, Cheryl

2017-11-01

Neuromyelitis optica (NMO) and NMO spectrum disorder (NMOSD) is a rare relapsing autoimmune disease of the central nervous system constituting less than 1% of demyelinating diseases (Jeffery and Buncic, 1996). It preferentially affects the optic nerves and spinal cord, with the brain parenchyma generally spared. Demyelinating lesions are characterised by longitudinally extensive transverse myelitis (LETM) and often longitudinally extensive optic neuritis. Following the discovery of a novel pathogenic antibody, Aquaporin 4 in 2004 (Lennon et al., 2004) this disease has been seen as a separate entity from Multiple Sclerosis (MS). We report the case of a severe AQP4 IgG case of NMO in a 10 year old child. This case unusually had a coexisting diagnosis of acute nephrotic syndrome which has only been reported once previously in the literature 2 . This article will examine some of the treatment challenges and the spectrum of co-existing autoimmune disease in NMOSD. Copyright © 2017. Published by Elsevier B.V.

Collagenous colitis (CC) is associated with autoimmune disorders. The aim of the present study was to investigate the relationship between CC and autoimmune disorders in a Swedish multicenter study. Patients with CC answered questionnaires about demographic data and disease activity. The patient's files were scrutinized for information about autoimmune diseases. A total number of 116 CC patients were included; 92 women, 24 men, median age 62 years (IQR 55-73). In total, 30.2% had one or more autoimmune disorder. Most common were celiac disease (CeD; 12.9%) and autoimmune thyroid disease (ATD, 10.3%), but they also had Sjögren's syndrome (3.4%), diabetes mellitus (1.7%) and conditions in skin and joints (6.0%). Patients with associated autoimmune disease had more often nocturnal stools. The majority of the patients with associated CeD or ATD got these diagnoses before the colitis diagnosis. Autoimmune disorders occurred in one-third of these patients, especially CeD. In classic inflammatory bowel disease (IBD), liver disease is described in contrast to CC where no cases occurred. Instead, CeD was prevalent, a condition not reported in classic IBD. Patients with an associated autoimmune disease had more symptoms. Patients with CC and CeD had an earlier onset of their colitis. The majority of the patients with both CC and CeD were smokers. Associated autoimmune disease should be contemplated in the follow-up of these patients.

APPEARANCE OF AUTOIMMUNE DISEASES IN PATIENTS WITH ENDOMETRIOSIS

Full Text Available Background. Endometriosis is a comon, complex gynecological syndrom defined as the growth of endometrial glands and stroma in an extra-uterine location. It affects 5 – 20 % of women of reproductive age.1 Nowadays, prevailing opinion about endometriosis is based on presumption, that endometriosis is a result of changed immune system, according to autoimmune theory.2, 3 Characteristics of autoimmune disease that are also found in endometriosis are female preponderance, multiorgan involvement, family occurence, possible genetic basis, response to hormonal manipulation, tissue damage, polyclonal B lymphocite activation, immunological abnormalities in T lymphocite and B lymphocite function and associated autoimmune disease. Women with endometriosis are more frequently affected by asthma, rheumatoid arthritis, systemic lupus erythematosus, Sjögren syndrom and Hashimoto’s thyroiditis. Autoimmune disease is characterized by the production of autoantibodies against components of apoptotic cells. Anti-endometrial antibodies of IgG and IgM classes could be detected in 60 % of endometriosis patients. They show reactivity in glandular epithelium and stroma. Anti-endothelial antibodies specifically react with vascular endothelium and might be with anti-endometrial antibodies partially responsible for failure of implantation leading to infertility, wich is common in endometriosis patients. Anti-nuclear antibodies are frequent serological findings in patients with autoimmune disease, and could be detected in 29–47 % of women with endometriosis.4 Generation of anti-nuclear antibodies is a risk factor for development of other autoimmune disease in women of reproductive age. Studies have shown conflicting results on the presence of anti-ovarian antibodies in the serum of endometriosis patients and in the peritoneal fluid. Their presence is one of the possible causes of infertility. Conclusions. Ethiopathogenesis of endometriosis still remains uncelar but

Gwizdek, Katarzyna; Michalski, Marek; Wojnicz, Romuald

2016-01-01

The Epstein-Barr virus (EBV), also known as human herpesvirus 4, is a member of the Herpesviridae virus family. EBV infection can cause infectious mononucleosis (IM) in the lytic phase of EBV’s life cycle. Past EBV infection is associated with lymphomas, and may also result in certain allergic and autoimmune diseases. Although potential mechanisms of autoimmune diseases have not been clearly elucidated, both genetic and environmental factors, such as infectious agents, are considered to be responsible for their development. In addition, EBV modifies the host immune response. The worldwide prevalence of autoimmune diseases shows how common this pathogen is. Normally, the virus stays in the body and remains dormant throughout life. However, this is not always the case, and a serious EBV-related illness may develop later in life. This explains the chronic course of autoimmune diseases that is often accompanied by exacerbations of symptoms. Based on the present studies, EBV infection can cause autoimmune diseases, such as systemic lupus erythematosus (SLE), multiple sclerosis (MS), rheumatoid arthritis (RA), Sjögren’s syndrome, and autoimmune hepatitis. The EBV has also been reported in patients with autoimmune thyroid disorders. Although EBV is not the only agent responsible for the development of autoimmune thyroid diseases, it can be considered a contributory factor. PMID:27833448

Hashimoto thyroiditis (HT) is the most common pediatric autoimmune endocrine disorder. It results in autoimmune-mediated thyroid gland destruction and is an organ-specific, typical autoimmune disease. The presence of antithyroid antibodies and the typical pattern on ultrasonography indicate the diagnosis. It is also frequently seen together with other autoimmune disorders including type 1 insulin-dependent diabetes, celiac disease, alopecia and vitiligo. Autoimmune hepatitis (AIH) is a chronic type of liver injury with an immune etiology that can frequently cause end-stage liver disease if left untreated. Autoimmune hepatitis patients may present with hepatitis, and the laboratory tests in the absence of other etiology usually reveal a positive immune serology together with elevated immunoglobulins and abnormal liver histology. It is interesting that HT and AIH are rarely seen together although both have an autoimmune etiology. 14-year-old male who was being followed-up for vitiligo presented with symptoms of a swelling at the neck and fatigue. He was diagnosed with HT after the tests and the liver enzymes were found to be high. The patient was also diagnosed with AIH after tests revealed that the liver enzyme elevation had continued for longer than six months. The thyroid functions and liver enzymes returned to normal and the symptoms decreased after sodium L-thyroxine replacement together with steroid and azathioprine treatment. We present this case as we believe it is the first pediatric patient diagnosed with HT, AIH and vitiligo.

Full Text Available Sjögren syndrome (SS is an autoimmune disease of the exocrine glands, characterized by focal lymphocytic infiltration and destruction of these glands. Neurologic complications are quite common, mainly involving the peripheral nervous system (PNS. The most common central nervous system (CNS manifestations are myelopathy and microcirculation vasculitis. However, specific diagnostic criteria for CNS SS are still lacking. We report two cases of primary SS in which the revealing symptom was cerebral venous thrombosis (CVT in the absence of genetic or acquired thrombophilias.

The most common reason of acquired hypothyroidism is autoimmune (Hashimoto) thyroiditis. Autoimmune thyroiditis can be atrophic or goitrogenic. Atrophic autoimmune thyroiditis (ATT) related acquired hypothyroidism causes interruption of growth, obesity, and bone age retardation in early ages while goitrogenic thyroiditis has a higher incidence rate and mostly presents with diffuse goiter. We discuss the effects of hypothyroidism on various systems through a case found to have pericardial effusion during the echocardiography performed after cardiac murmur was detected and later diagnosed with ATT related hypothyroidism.

Scleroderma of geriatric age and scleroderma-like paraneoplastic syndrome – description of two cases

Full Text Available Systemic sclerosis (Ssc is an autoimmune connective tissue disease of unknown origin, characterized by progressive fibrosis of the skin and internal organs. Immune reactions taking part in Ssc pathogenesis may contribute to cancer development; therefore patients with risk factors for this disease require observation for a neoplastic process. On the other hand, symptoms of Ssc may be a mask of various cancers. Differentiating between the idiopathic form of Ssc and scleroderma-like paraneoplastic syndrome often causes a lot of difficulties. The article presents two cases of Ssc at the beginning of the disease after 60 years of age. The first case was diagnosed as Ssc, whereas in the second case the defined diagnosis was scleroderma-like syndrome in the course of colorectal cancer. This paper presents an analysis of differential diagnostic procedures which were performed and led to the final diagnosis, mentions types of cancers co-occurring with Ssc and suggests a screening scheme for cancer development in patients with a diagnosis of Ssc.

Kleine-Levin syndrome is an extremely rare neurological entity characterized by recurrent episodes of hypersomnia which are sometimes associated with compulsive hyperphagia and behavioral changes. Autoimmunity has recently been proposed as a factor contributing to its pathogenesis. Immune thrombocytopenic purpura is a relatively common autoimmune disease showing a lot of complexity and uncertainty regarding its treatment regimens and its refractory nature in some cases. A 32-year-old Persian White man visited his private hematologist complaining of recent episodes of epistaxis and appearance of petechial lesions 24 hours after receiving a meningococcal vaccine. He had a history of immune thrombocytopenic purpura 13 years before his presentation. Based on his history and laboratory findings, his condition was diagnosed as a relapse of immune thrombocytopenic purpura and was managed accordingly. He did not respond to first-line corticosteroid regimens and later developed neurological symptoms as recurrent episodes of hypersomnia and hyperphagia. After a complete clinical and paraclinical evaluation and ruling out other possible conditions, he was given a diagnosis of Kleine-Levin syndrome. He was followed up for his immune thrombocytopenic purpura and received different treatment regimens none of which were adequately successful except intravenous immunoglobulin that was only temporarily effective. He has had 4 documented self-limited episodes of Kleine-Levin syndrome since his initial presentation. Immune thrombocytopenic purpura may be associated with meningococcal vaccination in adulthood. Responses to treatment in immune thrombocytopenic purpura vary among patients. Our patient only had a transient acceptable response to intravenous immunoglobulin while all other options failed to improve his platelet count. Concurrence of immune thrombocytopenic purpura and Kleine-Levin syndrome supports the role of autoimmunity as the proposed pathophysiological mechanism of

Various hypothalamic-pituitary diseases cause hypopituitarism. Inflammation related to autoimmunity also causes hypopituitarism. Hypophysitis is a representative disease caused by autoimmunity. Generally, anterior pituitary hormones are non-specifically impaired in this condition, but specific hormone defects have been reported in some cases. Anti-PIT-1 (pituitary-specific transcription factor 1) antibody syndrome is a novel clinical entity that presents an acquired combined pituitary hormone deficiency characterized by a specific defect in growth hormone, prolactin, and thyroid-stimulating hormone. Circulating anti-PIT-1 antibody along with various autoantibodies are detected with multiple endocrine organopathy, meeting the definition of autoimmune polyglandular syndrome. Mechanistically, cytotoxic T lymphocytes that specifically react with PIT-1 protein play an important role in the development of this syndrome.

Full Text Available Introduction. Autoimmune cholangitis or immunoglobulin G4-associated cholangitis (IAC has been recently regarded as a new clinical and histopathological entity and is a part of a complex autoimmune disorder - IgG4-related systemic disease (ISD. ISD is an autoimmune disease with multi-organic involvement, characterized with IgG4-positive plasmocytic infiltration of various tissues and organs with a consequent sclerosis, which responds well to steroid therapy. Most commonly affected organs are the pancreas (autoimmune pancreatitis, [AIP] and the common bile duct (IAC. IAC and cholangiocarcinoma (CCA share many clinical, laboratory and imaging findings. Case Outline. We present a case of a 60-year-old male with a biliary stricture of a common bile duct, which was clinically considered as a bile duct carcinoma and treated surgically. Definite histopathological findings and immunohistochemistry revealed profound chronic inflammation, showing lymphoplasmacytic IgG-positive infiltration of a resected part of a common bile duct, highly suggestive for the diagnosis of IAC. In addition, postoperative IgG4 serum levels were also increased. Conclusion. It is of primary clinical importance to make a difference between IAC and CCA, in order to avoid unnecessary surgical intervention. Therefore, IAC should be considered in differential diagnosis in similar cases.

Autoimmune gastritis is often suspected for its hematologic findings, and rarely the diagnosis is made for the presence of gastrointestinal symptoms. Aims of this cross-sectional study were to assess in a large cohort of patients affected by autoimmune gastritis the occurrence and the pattern of gastrointestinal symptoms and to evaluate whether symptomatic patients are characterized by specific clinical features.Gastrointestinal symptoms of 379 consecutive autoimmune gastritis patients were systematically assessed and classified following Rome III Criteria. Association between symptoms and anemia pattern, positivity to gastric autoantibodies, Helicobacter pylori infection, and concomitant autoimmune disease were evaluated.In total, 70.2% of patients were female, median age 55 years (range 17-83). Pernicious anemia (53.6%), iron deficiency anemia (34.8%), gastric autoantibodies (68.8%), and autoimmune disorders (41.7%) were present. However, 56.7% of patients complained of gastrointestinal symptoms, 69.8% of them had exclusively upper symptoms, 15.8% only lower and 14.4% concomitant upper and lower symptoms. Dyspepsia, subtype postprandial distress syndrome was the most represented, being present in 60.2% of symptomatic patients. Univariate and multivariate analyses showed that age gastritis is associated in almost 60% of cases with gastrointestinal symptoms, in particular dyspepsia. Dyspepsia is strictly related to younger age, no smoking, and absence of anemia.

Melkersson-Rosenthal syndrome (MRS) is a rare disorder of unknown cause. The classical triad of MRS is orofacial edema, recurrent facial paralysis, and a fissured tongue. We present a 9-year-old girl with a recurrent peripheral facial paralysis. She experienced the first episode of a peripheral facial paralysis on the same side without orofacial swelling and lingua plicata 1 year ago. She was diagnosed with Hashimoto thyroiditis 9 months earlier, as confirmed by an endocrinologic investigation. While the patient was hospitalized with recurrent facial paralysis, we found that serum levels of free thyroxine (1.3 ng/dL) and thyrotropin (0.4 uIU/mL) were within normal range, but the level of antithyroperoxidase antibodies (772.0 IU/mL) was very increased. She had been taking an oral prednisolone orally for 2 weeks. At the 1-month follow-up, the patient's symptoms had completely disappeared. The possible correlation between MRS and autoimmune disorders has been documented in only one report, which described an adult with autoimmune thyroiditis (Hashimoto thyroiditis) and MRS. We suggest that the co-occurrence of MRS and Hashimoto thyroiditis is not coincidental but linked to autoimmunity. Copyright © 2014 Elsevier Inc. All rights reserved.

Full Text Available Background. Autoimmune pancreatitis (AIP often mimics pancreatic cancer. The diagnosis of both conditions is difficult preoperatively let alone when they coexist. Several reports have been published describing pancreatic cancer in the setting of AIP. Case Report. The case of a 53-year-old man who presented with abdominal pain, jaundice, and radiological features of autoimmune pancreatitis, with a “sausage-shaped” pancreas and bulky pancreatic head with portal vein impingement, is presented. He had a normal serum IgG4 and only mildly elevated Ca-19.9. Initial endoscopic ultrasound-(EUS- guided fine-needle aspiration (FNA of the pancreas revealed an inflammatory sclerosing process only. A repeat EUS guided biopsy following biliary decompression demonstrated both malignancy and features of autoimmune pancreatitis. At laparotomy, a uniformly hard, bulky pancreas was found with no sonographically definable mass. A total pancreatectomy with portal vein resection and reconstruction was performed. Histology revealed adenosquamous carcinoma of the pancreatic head and autoimmune pancreatitis and squamous metaplasia in the remaining pancreas. Conclusion. This case highlights the diagnostic and management difficulties in a patient with pancreatic cancer in the setting of serum IgG4-negative, Type 2 AIP.

Full Text Available Abstract Introduction Devic's neuromyelitis optica is an inflammatory demyelinating disease that targets the optic nerves and spinal cord. It has a worldwide distribution and distinctive features that distinguish it from multiple sclerosis. There has been no previous report of neuromyelitis optica from our practice environment, and we are not aware of any case associated with antiphospholipid syndrome in an African person. Case presentation We report the case of a 28-year-old Nigerian woman who presented with neck pain, paroxysmal tonic spasms, a positive Lhermitte's sign and spastic quadriplegia. She later developed bilateral optic neuritis and had clinical and biochemical features of antiphospholipid syndrome. Her initial magnetic resonance imaging showed a central linear hyperintense focus in the intramedullary portion of C2 to C4. Repeat magnetic resonance imaging after treatment revealed resolution of the signal intensity noticed earlier. Conclusion Neuromyelitis optica should be considered in the differential diagnoses of acute myelopathy in Africans. We also highlight the unusual association with antiphospholipid syndrome. Physicians should screen such patients for autoimmune disorders.

Full Text Available Research shows that autoimmune encephalitis is associated with sleep disorders. Paraneoplastic neurological syndrome (PNS with Ma2 antibodies can cause sleep disorders, particularly narcolepsy and rapid eye movement sleep behavior disorder (RBD. Limbic encephalitis (LE and Morvan syndrome, associated with voltage - gated potassium channel (VGKC-complex antibodies, which include leucine-rich glioma-inactivated 1 (LGI1 antibody and contactin-associated protein 2 (Caspr2, can result in profound insomnia and other sleep disorders. Central neurogenic hypoventilation are found in patients with anti-N-methyl-D-aspartate (NMDA receptor encephalitis, whereas obstructive sleep apnea (OSA, stridor and parasomnia are prominent features of encephalopathy associated with IgLON5 antibodies. Sleep disorders are cardinal manifestations in patients with autoimmune encephalitis. Immunotherapy possiblely can improve clinical symptoms and prognosis in a positive way.

2012-04-01

Achalasia is a rare disease of the esophagus that has an unknown etiology. Genetic, infectious, and autoimmune mechanisms have each been proposed. Autoimmune diseases often occur in association with one another, either within a single individual or in a family. There have been separate case reports of patients with both achalasia and one or more autoimmune diseases, but no study has yet determined the prevalence of autoimmune diseases in the achalasia population. This paper aims to compare the prevalence of autoimmune disease in patients with esophageal achalasia to the general population. We retrospectively reviewed the charts of 193 achalasia patients who received treatment at Toronto's University Health Network between January 2000 and May 2010 to identify other autoimmune diseases and a number of control conditions. We determined the general population prevalence of autoimmune diseases from published epidemiological studies. The achalasia sample was, on average, 10-15 years older and had slightly more men than the control populations. Compared to the general population, patients with achalasia were 5.4 times more likely to have type I diabetes mellitus (95% confidence interval [CI] 1.5-19), 8.5 times as likely to have hypothyroidism (95% CI 5.0-14), 37 times as likely to have Sjögren's syndrome (95% CI 1.9-205), 43 times as likely to have systemic lupus erythematosus (95% CI 12-154), and 259 times as likely to have uveitis (95% CI 13-1438). Overall, patients with achalasia were 3.6 times more likely to suffer from any autoimmune condition (95% CI 2.5-5.3). Our findings are consistent with the impression that achalasia's etiology has an autoimmune component. Further research is needed to more conclusively define achalasia as an autoimmune disease. © 2011 Copyright the Authors.

Moebius' syndrome (MS) is characterized by a nonprogressive facial palsy associated with impairment in eye abduction, which can be uni- or bilateral. Some authors raise the possibility that patients with MS may suffer from social stigmatism due to their facial dysmorphism and that constant teasing and bullying perpetrated by people in the same social circle are adjuvants in the development of low self-esteem, behavioral problems, and even psychiatric disorders. Psychological stress, anxiety, and depression are factors contributing to both development and impairment of autoimmune diseases, such as systemic lupus erythematosus (SLE). The objective of this work is to report the case of a patient with MS who developed SLE. In the present case report, we have emphasized the importance of both clinical dental examination and surgeon-dentist in the early diagnosis of systemic diseases by considering that these conditions can affect both syndromic and normoreactive patients. © 2018 Special Care Dentistry Association and Wiley Periodicals, Inc.

Involvement of chronic epipharyngitis in autoimmune (auto-inflammatory) syndrome induced by adjuvants (ASIA).

The epipharynx is an immunologically active site even under normal conditions, and enhanced immunologic activation is prone to occur in response to an upper respiratory infection, air pollution, and possibly to vaccine adjuvants. Due to the potential link between the central nervous system and immune function, a relationship between epipharyngitis and autonomic nervous disturbance as well as autoimmune disease has been suggested. Various functional somatic symptoms have been described after human papillomavirus (HPV) vaccination, although a causal relationship has not been established. We examined the epipharynx in young women showing functional somatic symptoms following HPV vaccination. Surprisingly, despite having minimal symptoms involving the pharynx, all patients were found to have severe epipharyngitis. In addition, significant improvement in symptoms was seen in most patients who underwent epipharyngeal treatment. Thus, we speculate that the chronic epipharyngitis potentially caused by the vaccine adjuvant may be involved in the pathogenesis of functional somatic syndrome (FSS) post-HPV vaccination. Further, we suggest that epipharyngeal treatment may be effective for various types of FSS regardless of the initial cause, as well as for some autoimmune diseases, and that this may be an important direction in future research.

Monogenic autoimmune diseases of the endocrine system.

Johnson, Matthew B; Hattersley, Andrew T; Flanagan, Sarah E

2016-10-01

The most common endocrine diseases, type 1 diabetes, hyperthyroidism, and hypothyroidism, are the result of autoimmunity. Clustering of autoimmune endocrinopathies can result from polygenic predisposition, or more rarely, may present as part of a wider syndrome due to a mutation within one of seven genes. These monogenic autoimmune diseases show highly variable phenotypes both within and between families with the same mutations. The average age of onset of the monogenic forms of autoimmune endocrine disease is younger than that of the common polygenic forms, and this feature combined with the manifestation of other autoimmune diseases, specific hallmark features, or both, can inform clinicians as to the relevance of genetic testing. A genetic diagnosis can guide medical management, give an insight into prognosis, inform families of recurrence risk, and facilitate prenatal diagnoses. Copyright © 2016 Elsevier Ltd.

De novo autoimmune hepatitis after liver transplantation.

Lohse, Ansgar W; Weiler-Norman, Christina; Burdelski, Martin

2007-10-01

The Kings College group was the first to describe a clinical syndrome similar to autoimmune hepatitis in children and young adults transplanted for non-immune mediated liver diseases. They coined the term "de novo autoimmune hepatitis". Several other liver transplant centres confirmed this observation. Even though the condition is uncommon, patients with de novo AIH are now seen in most of the major transplant centres. The disease is usually characterized by features of acute hepatitis in otherwise stable transplant recipients. The most characteristic laboratory hallmark is a marked hypergammaglobulinaemia. Autoantibodies are common, mostly ANA. We described also a case of LKM1-positivity in a patients transplanted for Wilson's disease, however this patients did not develop clinical or histological features of AIH. Development of SLA/LP-autoantibodies is also not described. Therefore, serologically de novo AIH appears to correspond to type 1 AIH. Like classical AIH patients respond promptly to treatment with increased doses of prednisolone and azathioprine, while the calcineurin inhibitors cyclosporine or tacrolimus areof very limited value - which is not surprising, as almost all patients develop de novo AIH while receiving these drugs. Despite the good response to treatment, most patients remain a clinical challenge as complete stable remissions are uncommon and flares, relapses and chronic disease activity can often occur. Pathogenetically this syndrome is intriguing. It is not clear, if the immune response is directed against allo-antigens, neo-antigens in the liver, or self-antigens, possibly shared by donor and host cells. It is very likely that the inflammatory milieu due to alloreactive cells in the transplanted organ contribute to the disease process. Either leading to aberrant antigen presentation, or providing co-stimulatory signals leading to the breaking of self-tolerance. The development of this disease in the presence of treatment with calcineurin

A clinical criterion of the Wolfram syndrome is the coexistence of diabetes and optic atrophy recognized before the age of 15. Diabetes present in Wolfram syndrome is a result of the selective β cell loss and failed insulin secretion which is probably associated with non-autoimmune pathogenesis. The aim of the study was an evaluation of HLA subtypes and presence of β-cell autoantibodies in patients with molecularly confirmed Wolfram syndrome. 9 patients with Wolfram syndrome aged 10-24 years were examined. We also studied 218 patients with type 1 diabetes as a reference group. A control group of 176 healthy individuals was included in the study. Besides the clinical assessment the HLA typing by PCR-SSO was performed. Islet cell antibodies (ICA), antibodies to glutamic acid decarboxylase (GADA), thyrosine phosphatase antibodies (IA2A) and insulin antibodies (IAA) were also detected. In all nine patients the coexistence of diabetes with optic atrophy was observed and in 8/9 individuals additional symptoms were recognized. In patients with Wolfram syndrome a significantly lower age of diagnosis of diabetes (Me=5.0 years) than in type 1 diabetic children (Me=10.4; p=0.002) was observed. Studies of HLA subtypes demonstrated an increased prevalence of HLA-DQw1, DRB1⋅03 and/or 04 and DR2. A comparison of the frequency of the HLA alleles in patients with Wolfram syndrome with type 1 diabetic children showed a more frequent presence of the DRB1⋅1501 (p=0.03; OR=13.28 (2.44-72.12)) and DQB1⋅06 (p=0.016; OR=10.15 (2.49-41.35)) alleles in patients with Wolfram syndrome. Polish patients with Wolfram syndrome have a different profile of the HLA antigens with the presence of DR2, DQw1 and DRB3/4 allele and are negative for diabetes-related autoantibodies, which may confirm non-autoimmune β-cell destruction in this syndrome.

Sweet's syndrome is rare acute febrile neutrophilic dermatosis whose onset is either idiopathic or associated with other underlying conditions, such as infections, autoimmune diseases, pregnancy, use of certain medications, or malignancy. We report the case of a young male with known history of ulcerative colitis and abrupt onset of high fever, malaise, blurred vision and eruption of painful erythematous nodules and papules, localized on the head, neck, trunk and upper limbs. Ophthalmological examination established the diagnosis of anterior uveitis. Inflammatory markers were positive. Histological examination of skin lesions revealed a dense neutrophilic infiltrate of the dermis. Clinical, laboratory and histological findings were suggestive for the diagnosis of Sweet's syndrome and uveitis on a background of ulcerative colitis. Systemic and ophthalmic administration of corticotherapy leads to a prompt resolution of symptoms and inflammatory syndrome. The particularity of this case is the occurrence of two simultaneous extraintestinal manifestations in a young male with inflammatory bowel disease and colonic involvement. Although a relatively rare condition, Sweet's syndrome should be considered as a differential diagnosis in patients with acute onset of high fever and skin rash, as it may have notable internal involvement and can be easily treated.

Cytomegalovirus (CMV) infection remains a common infection after solid-organ transplantation. In the general population CMV disease is associated with Guillain-Barre syndrome (GBS), an autoimmune disease leading to an acute peripheral neuropathy, in 1 of 1000 cases. Interestingly, GBS is a rarely observed complication in solid-organ transplant recipients, possibly related to maintenance immunosuppression. We describe a case of CMV infection complicated by GBS in a kidney transplant recipient and review the literature.

Cricopharyngeal achalasia in connection with autoimmune disorders in a pre-adolescent patient: a case report

Full Text Available Cricopharyngeal achalasia is an uncommon cause of dysphagia, especially in children. Congenital form is known in neonates and infants. In older children this disease has been reported in very rare cases and mostly in connection with neurological and muscular diseases. We present a case of a 12-year-old girl with a four-year history of dysphagia. Esophagogastroduodenoscopy, radiological contrast swallow study and esophageal manometric study confrmed the diagnosis of cricopharyngeal achalasia. Te patient was successfully treated with dilatation of the upper esophageal sphincter. An initial attempt of dilatation appears to be a safe and effective option in the management of cricopharyngeal achalasia in children, and may prevent or at least postpone the need for myotomy. Following the diagnosis of cricopharyngeal achalasia, several autoimmune conditions were diagnosed. Our case report revealed that cricopharyngeal achalasia may occur in association with some other autoimmune conditions, and that autoimmunity may also play a role in cricopharyngeal achalasia itself

Our understanding of the pathogenic mechanisms and possible treatments of autoimmune diseases has significantly increased over the past decade. Nonetheless, numerous major issues remain open and such issues span from epidemiology to clinimetrics and from the role of infectious agents to the search for accurate biomarkers in paradigmatic conditions such as systemic lupus erythematosus, rheumatoid arthritis, and spondyloarthropathies. In the case of cardiovascular comorbidities of autoimmune diseases or, more generally, the pathogenesis of atherosclerosis, fascinating evidence points to a central role of autoimmunity and metabolic dysfunctions and a possible role of therapies targeting inflammation to ameliorate both conditions. Basic science and translational medicine contribute to identify common mechanisms that underlie different autoimmune diseases, as in the case of tumor necrosis factor alpha, and more recently vitamin D, autoantibodies, T and B regulatory cells, and microRNA. Finally, new therapies are expected to significantly change our approach to autoimmune diseases, as represented by the recent FDA approval of the first oral JAK inhibitor. The present article moves from the major topics that were discussed at the 2013 Asian Congress of Autoimmunity in Hong Kong to illustrate the most recent data from leading journals in autoimmunity and immunology.

Helicobacter pylori (H. pylori) is the main cause of chronic gastritis and a major risk factor for gastric cancer. This pathogen has also been considered a potential trigger of gastric autoimmunity, and in particular of autoimmune gastritis. However, a considerable number of reports have attempted to link H. pylori infection with the development of extra-gastrointestinal autoimmune disorders, affecting organs not immediately relevant to the stomach. This review discusses the current evidence in support or against the role of H. pylori as a potential trigger of autoimmune rheumatic and skin diseases, as well as organ specific autoimmune diseases. We discuss epidemiological, serological, immunological and experimental evidence associating this pathogen with autoimmune diseases. Although over one hundred autoimmune diseases have been investigated in relation to H. pylori, we discuss a select number of papers with a larger literature base, and include Sjögrens syndrome, rheumatoid arthritis, systemic lupus erythematosus, vasculitides, autoimmune skin conditions, idiopathic thrombocytopenic purpura, autoimmune thyroid disease, multiple sclerosis, neuromyelitis optica and autoimmune liver diseases. Specific mention is given to those studies reporting an association of anti-H. pylori antibodies with the presence of autoimmune disease-specific clinical parameters, as well as those failing to find such associations. We also provide helpful hints for future research. PMID:24574735

Fatal atypical reversible posterior leukoencephalopathy syndrome: a case report

Full Text Available Abstract Introduction Reversible posterior leukoencephalopathy syndrome – a reversible subacute global encephalopathy clinically presenting with headache, altered mental status, visual symptoms such as hemianopsia or cortical blindness, motor symptoms, and focal or generalized seizures – is characterized by a subcortical vasogenic edema symmetrically affecting posterior brain regions. Complete reversibility of both clinical signs and magnetic resonance imaging lesions is regarded as a defining feature of reversible posterior leukoencephalopathy syndrome. Reversible posterior leukoencephalopathy syndrome is almost exclusively seen in the setting of a predisposing clinical condition, such as pre-eclampsia, systemic infections, sepsis and shock, certain autoimmune diseases, various malignancies and cytotoxic chemotherapy, transplantation and concomitant immunosuppression (especially with calcineurin inhibitors as well as episodes of abrupt hypertension. We describe for the first time clinical, radiological and histological findings in a case of reversible posterior leukoencephalopathy syndrome with an irreversible and fatal outcome occurring in the absence of any of the known predisposing clinical conditions except for a hypertensive episode. Case presentation A 58-year-old Caucasian woman presented with a two-week history of subacute and progressive occipital headache, blurred vision and imbalance of gait and with no evidence for raised arterial blood pressure during the two weeks previous to admission. Her past medical history was unremarkable except for controlled arterial hypertension. Cerebral magnetic resonance imaging demonstrated cortical and subcortical lesions with combined vasogenic and cytotoxic edema atypical for both venous congestion and arterial infarction. Routine laboratory and cerebrospinal fluid parameters were normal. The diagnosis of reversible posterior leukoencephalopathy syndrome was established. Within hours after

Myelodysplastic Syndromes (MDS) and autoimmune disorders (AD): cause or consequence?

Science.gov (United States)

Braun, Thorsten; Fenaux, Pierre

2013-12-01

Myelodysplastic Syndromes (MDS) and Chronic Myelomonocytic Leukemia (CMML) are frequently associated with clinical manifestations of autoimmune disorders (AD) and inflammatory response of the immune system. AD accompanying MDS and CMML include vasculitis, seronegative polyarthritis and neutrophilic dermatosis. Rare AD including relapsing polychondritis is strongly associated with MDS as in a high proportion of those patients MDS is diagnosed during disease course. Antinuclear antibodies (ANA) are frequently found among MDS patients without clinical manifestation of AD. In a subset of patients, MDS and resulting cytopenias appear to be the consequence of auto reactive immunologic activity and may respond to immunosuppressive treatment (IST). Increased release of inflammatory cytokines like tumor necrosis factor-(TNF)-α and interferon (IF)-γ triggers apoptosis of myeloid precursor cells leading to cytopenias. Impaired function of immune cells including cytotoxic, regulatory (Treg), helper (Th17) T cells and NK cells also appears to predict response to IST, outcome and occurrence of AD.

Full Text Available Vogt-Koyanagi-Harada syndrome (VKH syndrome is named after ophthalmologists Alfred Vogt from Switzerland and Yoshizo Koyanagi and Einosuke Harada from Japan. It is an uncommon multisystem disorder characterized by chronic, bilateral, diffuse granulomatous uveitis with associated dermatological, neurological and auditory manifestations. It is an autoimmune disease directed against melanocytes. We report a case presenting with vitiligo, auditory defect with additional dextrocardia.

An Overlapping Case of Miller Fisher Syndrome, Bickerstaff’s Encephalitis, and the ASMAN Variant of Guillain-Barre Syndrome

2016-01-01

Full Text Available A 56-year-old man presented with a 3-day history of progressive tingling of the hands, unsteadiness, and diplopia. He was initially diagnosed clinically with Miller Fisher Syndrome (MFS but later developed limb weakness consistent with Guillain-Barre Syndrome (GBS and subsequently reduced consciousness consistent with Bickerstaff’s brainstem encephalitis (BBE. Neurophysiology revealed an axonal motor and sensory neuropathy, in keeping with the Acute Motor and Sensory Axonal Neuropathy (AMSAN variant of GBS. We believe that our patient had an MFS-AMSAN-BBE overlap syndrome. This is supported by his glycolipid antibody profile with high titres of anti-GQ1b IgG antibody and anti-GD1a IgG antibody. Anti-GQ1b antibodies are frequently found in both MFS and BBE and the anti-GD1a antibody is associated with axonal forms of GBS. Overlapping cases of MFS and BBE are well described, and because the same antibody is often found in both conditions, it is thought that they share a common autoimmune mechanism. BBE has also been previously reported in association with GBS lending support that it also lies on the same spectrum. This overlapping case of ASMAN variant of GBS, MFS, and BBE provides further support that these conditions are part of the same spectrum.

Presumed Isotretinoin-Induced, Concomitant Autoimmune Thyroid Disease and Ocular Myasthenia Gravis: A Case Report

2012-11-01

Full Text Available Introduction: There are many adverse effects that have been described for isotretinoin. To the best of our knowledge, this is the first report of a possible association of oral isotretinoin intake with autoimmune thyroiditis and ocular myasthenia gravis (OMG. Case Presentation: A 19-year-old Caucasian male, who had used oral isotretinoin for severe acne disease for the previous six months, was referred to our clinic. He had a three-week history of diplopia and variable bilateral ptosis. Physical examination showed moderate periorbital edema and limitations of up- and down-gaze in the left eye. Laboratory findings and thyroid ultrasound were consistent with autoimmune thyroiditis. Antithyroid therapy did not relieve the clinical symptoms. Concomitant OMG was suspected. Variable ptosis and a positive response to oral prednisolone of 40 mg/day and pyridostigmine of 360 mg/day supported the diagnosis of concomitant autoimmune thyroiditis and OMG. Conclusion: Autoimmune disorders may be triggered by oral isotretinoin treatment. Clinicians prescribing isotretinoin should be aware of the possible association between isotretinoin intake and concomitant autoimmune thyroiditis and OMG.

Full Text Available Autoimmune diseases are commonly encountered in dermatology practice. While the association of two autoimmune diseases in the same individual is not unknown, it is relatively rare for the second disease to be suspected based on cutaneous manifestations. We present two such cases wherein cutaneous manifestations were the first clue to the development of lupus erythematosus in a setting of autoimmune thyroiditis. Further, we have reviewed literature on this uncommon occurrence and discuss various aspects of this association.

Clinical Spectrum of Stiff Person Syndrome: A Review of Recent Reports

2016-03-01

Full Text Available Background: “Classic” stiff person syndrome (SPS features stiffness, anti-glutamic acid decarboxylase (anti-GAD antibodies, and other findings. Anti-GAD antibodies are also detected in some neurological syndromes (such as ataxia in which stiffness is inconsistently present. Patients with otherwise “classic” SPS may either lack anti-GAD antibodies or be seropositive for others. Hence, SPS cases appear to fall within a clinical spectrum that includes conditions such as progressive encephalomyelitis with rigidity and myoclonus (PERM, which exhibits brainstem and autonomic features. We have compiled herein SPS-spectrum cases reported since 2010, and have segregated them on the basis of likely disease mechanism (autoimmune, paraneoplastic, or cryptogenic for analysis. Methods: The phrases “stiff person syndrome”, “PERM”, “anti-GAD antibody syndrome”, and “glycine receptor antibody neurological disorders” were searched for in PubMed in January 2015. The results were narrowed to 72 citations after excluding non-English and duplicate reports. Clinical descriptions, laboratory data, management, and outcomes were categorized, tabulated, and analyzed. Results: Sixty-nine autoimmune, 19 paraneoplastic, and 13 cryptogenic SPS-spectrum cases were identified. SPS was the predominant diagnosis among the groups. Roughly two-thirds of autoimmune and paraneoplastic cases were female. Anti-GAD antibodies were most frequently identified, followed by anti-amphiphysin among paraneoplastic cases and by anti-glycine receptor antibodies among autoimmune cases. Benzodiazepines were the most commonly used medications. Prognosis seemed best for cryptogenic cases; malignancy worsened that of paraneoplastic cases. Discussion: Grouping SPS-spectrum cases by pathophysiology provided insights into work-up, treatment, and prognosis. Ample phenotypic and serologic variations are present within the categories. Ruling out malignancy and autoimmunity is

Reversible lacrimal gland-protective regulatory T-cell dysfunction underlies male-specific autoimmune dacryoadenitis in the non-obese diabetic mouse model of Sjögren syndrome

CD4+ CD25+ Foxp3+ regulatory T (Treg) cells are required to maintain immunological tolerance; however, defects in specific organ-protective Treg cell functions have not been demonstrated in organ-specific autoimmunity. Non-obese diabetic (NOD) mice spontaneously develop lacrimal and salivary gland autoimmunity and are a well-characterized model of Sjögren syndrome. Lacrimal gland disease in NOD mice is male-specific, but the role of Treg cells in this sex-specificity is not known. This study aimed to determine if male-specific autoimmune dacryoadenitis in the NOD mouse model of Sjögren syndrome is the result of lacrimal gland-protective Treg cell dysfunction. An adoptive transfer model of Sjögren syndrome was developed by transferring cells from the lacrimal gland-draining cervical lymph nodes of NOD mice to lymphocyte-deficient NOD-SCID mice. Transfer of bulk cervical lymph node cells modelled the male-specific dacryoadenitis that spontaneously develops in NOD mice. Female to female transfers resulted in dacryoadenitis if the CD4+ CD25+ Treg-enriched population was depleted before transfer; however, male to male transfers resulted in comparable dacryoadenitis regardless of the presence or absence of Treg cells within the donor cell population. Hormone manipulation studies suggested that this Treg cell dysfunction was mediated at least in part by androgens. Surprisingly, male Treg cells were capable of preventing the transfer of dacryoadenitis to female recipients. These data suggest that male-specific factors promote reversible dysfunction of lacrimal gland-protective Treg cells and, to our knowledge, form the first evidence for reversible organ-protective Treg cell dysfunction in organ-specific autoimmunity.

2016-04-01

Obstetric antiphospholipid syndrome is an acquired autoimmune disorder that is associated with various obstetric complications and, in the absence of prior history of thrombosis, with the presence of antiphospholipid antibodies directed against other phospholipids, proteins called cofactors or PL-cofactor complexes. Although the obstetric complications have been related to the procoagulant properties of antiphospholipid antibodies, pathological studies of human placenta have shown the proinflammatory capacity of antiphospholipid antibodies via the complement system and proinflammatory cytokines. There is no general agreement on which antiphospholipid antibodies profile (laboratory) confers the greatest obstetric risk, but the best candidates are categories I and IIa. Combined treatment with low doses of aspirin and heparin achieves good obstetric and maternal outcomes. In this study, we also review the therapeutic possibilities in refractory cases, although the likelihood of progressing to other autoimmune diseases is low. We briefly comment on incomplete obstetric antiphospholipid syndrome, also known as antiphospholipid antibody-mediated pregnancy morbidity syndrome.

Shimosegawa, Tooru; Kanno, Atsushi

2009-01-01

Since the rediscovery and definition of autoimmune pancreatitis (AIP) by Yoshida et al. in 1995, the disease has been attracting attention because of its unique clinical features and practical issues. This disease shows very impressive imaging findings, serological changes, and characteristic histopathology. It occurs most commonly in elderly males with painless jaundice or mild abdominal pain; resemblance in imaging findings between AIP and pancreatobiliary cancers poses an important practical issue of differentiation. With increasing recognition of AIP and accumulation of cases, another important feature of this disease has been revealed, i.e., association of extrapancreatic organ involvements. Initially misunderstood because it can be accompanied by other autoimmune disorders, such as Sjögren's syndrome or primary sclerosing cholangitis (PSC), AIP is now known to be associated with unique types of sialadenitis and cholangitis distinct from Sjögren's syndrome or PSC. Now the concept of "IgG4-related sclerosing disease" has become widely accepted and the list of organs involved continues to increase. With worldwide recognition, an emerging issue is the clinical definition of other possible types of autoimmune-related pancreatitis called "idiopathic duct-centric chronic pancreatitis (IDCP)" and "AIP with granulocyte epithelial lesion (GEL)" and their relation to AIP with lymphoplasmacytic sclerosing pancreatitis (LPSP). The time has arrived to establish clinical diagnostic criteria of AIP based on international consensus and to discuss regional and racial differences in the clinicopathological features of AIP. Consensus guidelines are also required for the ideal use of steroids in the treatment of AIP to suppress recurrence efficiently with minimal side effects. There are many issues to be settled in AIP; international collaboration of experts in the pancreas field is necessary to clarify the entire picture of this unique and important disease.

Full Text Available Background. Studied immune aspects of the pathogenesis of autoimmune thyroiditis (AIT, which occupies the first place among human autoimmune pathologies. Treatment of the disease is based on thyroid hormones (TH replacement therapy. TH are today considered to be super antigens in autoimmune inflammation of the thyroid gland. Aims. On the basis of complex assessment of hormonal and immunological markers (TSH, TH, Treg, the Th1-, Th2-, Th17-marker cytokines with a research of possible interrelations of their indicators at patients with various clinical options of a current of AIT initially and against the background of replacement therapy of TH to define differences in functional activity of various types of immunocompetent cages depending on weight of inflammatory process for forecasting of a further clinical current of AIT, optimization of protocols of therapy and timely correction of strategy of treatment. Methods. In a prospective study, patients with AIT were evaluated for serum levels of cytokines and their receptors before initiating TH replacement therapy and on treatment by means of the ELISA modern methods with immuneсhemiluminescence and electroсhemiluminescence ways of detection. Results. Patients suffering from AIT showed an excess production of Th1-, Th2-, Th17- and Tregs marker cytokines with a deficiency of TGF-β1, closely connected with autoimmune hypothyroidism severity. Under pressure of TH therapy the indices of most cytokines decreased or improved, with the exception of IL-6, IL-8, IL-2, IFN-g, TNF-α. The greatest variations from the normal range were recorded in the complicated hypothyroidism. Conclusions. High serum TNF-α level in the onset of the disease is an important marker for the unfavourable AIT course and a predictor of hormone replacement therapy in case of its subclinical course. Safety indexes of functional thyroid epithelium are systemic levels of IL-8 and IL-22, their dynamic reduction in blood serum is an

Insulin autoimmune syndrome (IAS) or Hirata's disease is a rare disorder characterized by hypoglycemia secondary to insulin autoantibodies (IAb). Over 200 patients have been described from Japan with significantly less numbers being reported from outside the Orient. IAS is more common in patients older than 40 yr of age with reports in the pediatric age group being notably rarer. Exposure to sulfhydryl group containing medications is implicated in the pathogenesis of this syndrome. In this report, we describe a case of IAS in an African-American adolescent. A 16-yr-old healthy African-American male was diagnosed with Graves' disease and started on Methimazole. Four weeks later, he was found unconscious and hypoglycemic (blood sugar 1.5 mmol/L). Evaluation was negative for insulinoma. Insulin antibodies were positive. Oral glucose tolerance test revealed elevated free insulin concentrations with disproportionately elevated total insulin levels. The patient was started on prednisone, diazoxide, and propranolol for management of IAS and hyperthyroidism. Thyroid radio-ablation was subsequently undertaken. The doses of prednisone and diazoxide were tapered and these medications discontinued after 9 months. The insulin antibody levels decreased gradually and became undetectable in 6 months with resolution of the hypoglycemia. © 2012 John Wiley & Sons A/S.

Autoimmune Hepatitis and Celiac Disease: Case Report Showing an Entero-Hepatic Link

Francesco Tovoli

2010-10-01

Full Text Available Celiac disease is an autoimmune disorder primarily targeting the small bowel, although extraintestinal extensions have been reported. The autoimmune processes can affect the liver with manifestations such as primary biliary cirrhosis and autoimmune hepatitis. We describe a 61-year-old woman with celiac disease and an increased levels of aminotransferases. The persistence of increased levels of aminotransferases after 1 year of gluten-free diet and the positivity for an anti-nuclear and anti-double-strand DNA antibodies led to a misdiagnosis of systemic lupus erythematosus-related hepatitis. Based on these findings the patient was placed on steroids, which after a few months were stopped because of the onset of diabetes mellitus. Soon after steroid withdrawal, the patient had a marked increase in aminotransferases and γ-globulins, and a liver biopsy revealed chronic active hepatitis. A course of three months of steroids and azathioprine normalized both biochemical and clinical parameters. Currently the patient is symptom-free and doing well. In conclusion, a hypertransaminasemia persisting after a gluten-free diet should be interpreted as a sign of coexisting autoimmune liver disease. Any autoantibody positivity (in this case to ANA and anti-dsDNA should be carefully considered in order to avoid misdiagnosis delaying appropriate clinical management.

Immune mechanism shares a common pathway both for systemic autoimmune diseases and periodontal diseases. Scientific exploration of literature revealed limited studies on the association between systemic autoimmune diseases and periodontal diseases in India. The aim of the study is to find whether the presence of systemic autoimmune diseases in an individual is a risk factor for the development of periodontal disease. This was a hospital-based case-control study. A sample of 253 patients with systemic autoimmune diseases, attending the Rheumatology Department of Government General Hospital, Chennai-3, and 262 patients without systemic autoimmune diseases, attending the outpatient department of the Tamil Nadu Government Dental College and Hospital, Chennai-3, constituted the case and control groups, respectively. Age, gender, and oral hygiene status matching was done. Oral hygiene status was assessed using oral hygiene index (OHI) and periodontal status was assessed using community periodontal index (CPI) and loss of attachment (LOA) index. Statistical analysis was done using SPSS version 15 (SPSS Inc, 2006, Chicago). Results showed 99.2% and 73.9% prevalence of gingivitis and periodontitis, respectively, in the case group as compared to 85.5% and 14.9%, respectively, in the control group. There is no linear relationship between OHI scores and prevalence of periodontitis (CPI and LOA scores) in the case group. Patients suffering from systemic autoimmune diseases showed more prevalence of periodontal diseases irrespective of oral hygiene scores. It is postulated that the presence of systemic autoimmune diseases may pose a risk for the development of periodontal diseases.

Management of phenytoin-induced gingival enlargement in a patient with antiphospholipid antibody syndrome: A rare case report

Directory of Open Access Journals (Sweden)

Shilpa Sarvesh Urolagin

2016-01-01

Full Text Available Antiphospholipid antibody (APLA syndrome is a noninflammatory autoimmune disease, with innumerable clinical manifestations ranging from recurrent thrombosis and pregnancy morbidity to valvular lesions, transverse myelitis, thrombocytopenia, and hemolytic anemia. APLAs in antiphospholipid syndrome (APS are well-known risk factors for cerebrovascular accidents. Stroke is the most common manifestation of APS in the central nervous system. Gingival enlargement is a known side effect of phenytoin which is an antiepileptic drug. This can have a significant effect on the quality of life as well as increasing the oral bacterial load by generating plaque retention sites. The management of gingival overgrowth seems to be directed at controlling gingival inflammation through a good oral hygiene regimen. Thus, this case report aims to describe the conservative management of phenytoin-induced gingival enlargement combined with inflammatory enlargement in a patient with APLA syndrome.

Personal history of autoimmune diseases is consistently associated with increased risk of non-Hodgkin lymphoma. In contrast, there are limited data on risk of Hodgkin lymphoma following autoimmune diseases and almost no data addressing whether there is a familial association between the conditions. Using population-based linked registry data from Sweden and Denmark, 32 separate autoimmune and related conditions were identified from hospital diagnoses in 7476 case subjects with Hodgkin lymphoma, 18,573 matched control subjects, and more than 86,000 first-degree relatives of case and control subjects. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) as measures of relative risks for each condition using logistic regression and also applied multivariable hierarchical regression models. All P values are two-sided. We found statistically significantly increased risks of Hodgkin lymphoma associated with personal histories of several autoimmune conditions, including rheumatoid arthritis (OR = 2.7, 95% CI = 1.9 to 4.0), systemic lupus erythematosus (OR = 5.8, 95% CI = 2.2 to 15.1), sarcoidosis (OR = 14.1, 95% CI = 5.4 to 36.8), and immune thrombocytopenic purpura (OR = infinity, P = .002). A statistically significant increase in risk of Hodgkin lymphoma was associated with family histories of sarcoidosis (OR = 1.8, 95% CI = 1.01 to 3.1) and ulcerative colitis (OR = 1.6, 95% CI = 1.02 to 2.6). Personal or family history of certain autoimmune conditions was strongly associated with increased risk of Hodgkin lymphoma. The association between both personal and family histories of sarcoidosis and a statistically significantly increased risk of Hodgkin lymphoma suggests shared susceptibility for these conditions.

Autoantibodies in Senear-Usher Syndrome: Cross-Reactivity or Multiple Autoimmunity?

Directory of Open Access Journals (Sweden)

María Elena Pérez-Pérez

2012-01-01

Full Text Available Senear-Usher syndrome or pemphigus erythematosus is a pathology that overlaps clinically and serologically with pemphigus foliaceus and lupus erythematosus. Skin biopsies of patients with pemphigus erythematosus reveal acantholysis and deposits of immunoglobulins in desmosomes, and they are positive in the lupus band test. In the present paper, we determined whether the autoantibodies associated with pemphigus erythematosus targeted a single antigen or multiple antigens as a result of the stimulation of independent B cell clones. Our present paper demonstrates that patients with pemphigus erythematosus produce both antiepithelial antibodies specific for desmoglein 1 and 3 and antinuclear antibodies specific for Ro, La, Sm, and double-stranded DNA antigens. After eluting specific anti-epithelial or anti-nuclear antibodies, which were recovered and tested using double-fluorescence assays, a lack of cross-reactivity was demonstrated between desmosomes and nuclear and cytoplasmic lupus antigens. This result suggests that autoantibodies in pemphigus erythematosus are directed against different antigens and that these autoantibodies are produced by independent clones. Given these clinical and serological data, we suggest that pemphigus erythematosus behaves as a multiple autoimmune disease.

Sjögren's syndrome in a 25-year-old female: A case study

Bacem A.E.O. Khalele

2016-12-01

Full Text Available Sjögren syndrome (SS is an autoimmune epithelitis characterized by lymphocytic glandular infiltration and various extraglandular manifestations. SS is usually encountered in middle-aged females (>50 years. Immunological, viral, hereditary, environmental and hormonal etiologic factors are controversially proposed with regard to the pathogenesis of SS with no upper hand given. The present study reports an atypical case of SS in a 25-year-old female who was closely followed up for three years. Being pregnant in 2015, SS ran a total remission course but did relapse more aggressively after delivery. Immunologically implicating, the possible interpretation, which may account for such a pathological fluctuation, is also tackled.

Summary Background: Sjögren syndrome (SS) is an autoimmune-lymphoproliferative disorder characterized by mononuclear cell infiltration of exocrine glands. Clinically, Sjögren syndrome (SS) has a wide spectrum, varying from autoimmune exocrinopathy to systemic involvement. There have been few cases reporting that primary SS developed with distal renal tubular acidosis clinically. Case Report: Here, we present a case with primary Sjögren syndrome accompanied by hypopotassemic paralysis due to renal tubular acidosis. Severe hypopotassemia, hyperchloremic metabolic acidosis, alkaline urine and disorder in urinary acidification test were observed in the biochemical examination of the 16-year-old female patient, who had applied to our clinic for extreme loss of muscle force. After the examinations it was determined that the patient had developed Type 1 RTA (distal RTA) due to primary Sjögren syndrome. Potassium and alkaline replacement was made and an immediate total recovery was achieved. Conclusions: Hypopotassemic paralysis due to primary Sjögren syndrome is a rare but severe disorder that could lead to death if not detected early and cured appropriately. Thus, effective treatment should be immediately initiated in cases where severe hypopotassemia is accompanied by metabolic acidosis, and the cases should also be examined for extraglandular involvement of SS.

Dose-response study of thimerosal-induced murine systemic autoimmunity

International Nuclear Information System (INIS)

Havarinasab, S.; Lambertsson, L.; Qvarnstroem, J.; Hultman, P.

2004-01-01

The organic compound ethylmercurithiosalicylate (thimerosal), which is primarily present in the tissues as ethylmercury, has caused illness and several deaths due to erroneous handling when used as a disinfectant or as a preservative in medical preparations. Lately, possible health effects of thimerosal in childhood vaccines have been much discussed. Thimerosal is a well-known sensitizing agent, although usually of no clinical relevance. In rare cases, thimerosal has caused systemic immune reactions including acrodynia. We have studied if thimerosal might induce the systemic autoimmune condition observed in genetically susceptible mice after exposure to inorganic mercury. A.SW mice were exposed to 1.25-40 mg thimerosal/l drinking water for 70 days. Antinucleolar antibodies, targeting the 34-kDa protein fibrillarin, developed in a dose-related pattern and first appeared after 10 days in the two highest dose groups. The lowest observed adverse effect level (LOAEL) for antifibrillarin antibodies was 2.5 mg thimerosal/l, corresponding to an absorbed dose of 147 μg Hg/kg bw and a concentration of 21 and 1.9 μg Hg/g in the kidney and lymph nodes, respectively. The same LOAEL was found for tissue immune-complex deposits. The total serum concentration of IgE, IgG1, and IgG2a showed a significant dose-related increase in thimerosal-treated mice, with a LOAEL of 5 mg thimerosal/l for IgG1 and IgE, and 20 mg thimerosal/l for IgG2a. The polyclonal B-cell activation showed a significant dose-response relationship with a LOAEL of 10 mg thimerosal/l. Therefore, thimerosal induces in genetically susceptible mice a systemic autoimmune syndrome very similar to that seen after treatment with inorganic mercury, although a higher absorbed dose of Hg is needed using thimerosal. The autoimmune syndrome induced by thimerosal is different from the weaker and more restricted autoimmune reaction observed after treatment with an equipotent dose of methylmercury

Autoimmune hematological diseases (AHDs) may occur after allogeneic hematopoietic stem cell transplantation (HSCT), but reports on these complications in large cohorts of pediatric patients are lacking. Between 1998 and 2011, 1574 consecutive children underwent allogeneic HSCT in 9 Italian centers. Thirty-three children (2.1%) developed AHDs: 15 autoimmune hemolytic anemia (45%), 10 immune thrombocytopenia (30%), 5 Evans' syndrome (15%), 2 pure red cell aplasia (6%), and 1 immune neutropenia (3%). The 10-year cumulative incidence of AHDs was 2.5% (95% confidence interval, 1.7 to 3.6). In a multivariate analysis, the use of alternative donor and nonmalignant disease was statistically associated with AHDs. Most patients with AHDs (64%) did not respond to steroids. Sustained complete remission was achieved in 87% of cases with the anti-CD20 monoclonal antibody (rituximab). Four patients (9%) (1 autoimmune hemolytic anemia, 1 Evans' syndrome, 2 immune thrombocytopenia) died at a median of 87 days after AHD diagnosis as a direct or indirect consequence of their disorder. Our data suggest that AHDs are a relatively rare complication occurring after HSCT that usually respond to treatment with rituximab.

Auto-immune hepatitis first presenting in the early postpartum period is rare. Immunosuppressive effects of pregnancy result in delayed manifestation of auto-immune hepatitis, and in established cases, the spontaneous improvements are there. Auto-immune hepatitis should be considered in the differential diagnosis of liver dysfunction first presenting in the early postpartum period. A case of postpartum hepatitis of auto-immune aetiology is being presented here. It is disease of unknown aetiology, characterised by inflammation of liver (as evidenced by raised serum transaminases, presence of interface hepatitis on histological examination), hypergammaglobulinaemia (> 1.5 times normal), presence of auto-antibodies [(antinuclear antibodies (ANA)], smooth muscle antibody (SMA) and antibody to liver-kidney microsome type 1 (LKM1) in the absence of viral markers ie, hepatitis B (HBsAg) and C (AntiHCV) and excellent response to corticosteroid therapy.

RNAi Therapeutics in Autoimmune Disease

Directory of Open Access Journals (Sweden)

Seunghee Cha

2013-03-01

Full Text Available Since the discovery of RNA interference (RNAi, excitement has grown over its potential therapeutic uses. Targeting RNAi pathways provides a powerful tool to change biological processes post-transcriptionally in various health conditions such as cancer or autoimmune diseases. Optimum design of shRNA, siRNA, and miRNA enhances stability and specificity of RNAi-based approaches whereas it has to reduce or prevent undesirable immune responses or off-target effects. Recent advances in understanding pathogenesis of autoimmune diseases have allowed application of these tools in vitro as well as in vivo with some degree of success. Further research on the design and delivery of effectors of RNAi pathway and underlying molecular basis of RNAi would warrant practical use of RNAi-based therapeutics in human applications. This review will focus on the approaches used for current therapeutics and their applications in autoimmune diseases, including rheumatoid arthritis and Sjögren’s syndrome.

2008-07-01

Full Text Available Abstract Background Polymorphisms within the insulin gene can influence insulin expression in the pancreas and especially in the thymus, where self-antigens are processed, shaping the T cell repertoire into selftolerance, a process that protects from β-cell autoimmunity. Methods We investigated the role of the -2221Msp(C/T and -23HphI(A/T polymorphisms within the insulin gene in patients with a monoglandular autoimmune endocrine disease [patients with isolated type 1 diabetes (T1D, n = 317, Addison's disease (AD, n = 107 or Hashimoto's thyroiditis (HT, n = 61], those with a polyglandular autoimmune syndrome type II (combination of T1D and/or AD with HT or GD, n = 62 as well as in healthy controls (HC, n = 275. Results T1D patients carried significantly more often the homozygous genotype "CC" -2221Msp(C/T and "AA" -23HphI(A/T polymorphisms than the HC (78.5% vs. 66.2%, p = 0.0027 and 75.4% vs. 52.4%, p = 3.7 × 10-8, respectively. The distribution of insulin gene polymorphisms did not show significant differences between patients with AD, HT, or APS-II and HC. Conclusion We demonstrate that the allele "C" of the -2221Msp(C/T and "A" -23HphI(A/T insulin gene polymorphisms confer susceptibility to T1D but not to isolated AD, HT or as a part of the APS-II.

Autoimmune AQP4 channelopathies and neuromyelitis optica spectrum disorders.

Science.gov (United States)

Hinson, Shannon R; Lennon, Vanda A; Pittock, Sean J

2016-01-01

Neuromyelitis optica (NMO) spectrum disorders (SD) represent an evolving group of central nervous system (CNS)-inflammatory autoimmune demyelinating diseases unified by a pathogenic autoantibody specific for the aquaporin-4 (AQP4) water channel. It was historically misdiagnosed as multiple sclerosis (MS), which lacks a distinguishing biomarker. The discovery of AQP4-IgG moved the focus of CNS demyelinating disease research from emphasis on the oligodendrocyte and myelin to the astrocyte. NMO is recognized today as a relapsing disease, extending beyond the optic nerves and spinal cord to include brain (especially in children) and skeletal muscle. Brain magnetic resonance imaging abnormalities, identifiable in 60% of patients at the second attack, are consistent with MS in 10% of cases. NMOSD-typical lesions (another 10%) occur in AQP4-enriched regions: circumventricular organs (causing intractable nausea and vomiting) and the diencephalon (causing sleep disorders, endocrinopathies, and syndrome of inappropriate antidiuresis). Advances in understanding the immunobiology of AQP4 autoimmunity have necessitated continuing revision of NMOSD clinical diagnostic criteria. Assays that selectively detect pathogenic AQP4-IgG targeting extracellular epitopes of AQP4 are promising prognostically. When referring to AQP4 autoimmunity, we suggest substituting the term "autoimmune aquaporin-4 channelopathy" for the term "NMO spectrum disorders." Randomized clinical trials are currently assessing the efficacy and safety of newer immunotherapies. Increasing therapeutic options based on understanding the molecular pathogenesis is anticipated to improve the outcome for patients with AQP4 channelopathy. © 2016 Elsevier B.V. All rights reserved.

A New Mutation Causing Progressive Familiar Intrahepatic Cholestasis Type 3 in Association with Autoimmune Hepatitis

Directory of Open Access Journals (Sweden)

Hugo M Oliveira

2017-03-01

Full Text Available Background: Some patients exhibit features of both autoimmune hepatitis (AIH and primary sclerosing cholangitis (PSC. Similarly, patients with progressive familial intrahepatic cholestasis type 3 (PFIC3 may share histological features with PSC. Case report: We report the case of a 22-year-old man who, since he was 5 years of age, has presented with pruritus, an approximately ninefold elevation of aminotransferases, and γ-glutamyl transferase levels ~10 times the upper limit. Initially he was diagnosed with an overlap syndrome of small duct PSC plus AIH. However, fluctuations in liver enzymes were observed over the following years. Analysis of the ABCB4 gene indicated the diagnosis of PFIC3, revealing a mutation not previously reported. Conclusion: With this case report we aim to describe a new mutation, raise awareness of this rare pathology and highlight the importance of genetic testing of the ABCB4 gene in patients with autoimmune liver disease (mainly small duct PSC with incomplete response to immunosuppressive treatment.

Simultaneous Combined Myositis, Inflammatory Polyneuropathy, and Overlap Myasthenic Syndrome

Full Text Available Immune-mediated neuromuscular disorders include pathologies of the peripheral nervous system, neuromuscular junction, and muscles. If overlap syndromes (or the association of almost two autoimmune disorders are recognized, the simultaneous occurrence of several autoimmune neuromuscular disorders is rare. We describe two patients presenting the simultaneous occurrence of inflammatory neuropathy, myositis, and myasthenia gravis (with positive acetylcholine receptor antibodies. For each patient, we carried out a pathological analysis (nerve and muscle and an electrophysiological study (and follow-up. To our knowledge, this is the first description of such a triple immune-mediated neuromuscular syndrome. We compared our observations with a few other cases of simultaneous diagnosis of two inflammatory neuromuscular disorders.

Elucidating the Role of Hyposalivation and Autoimmunity in Oral Candidiasis

Billings, Monisha; Dye, Bruce A.; Iafolla, Timothy; Grisius, Margaret; Alevizos, Ilias

2016-01-01

Introduction Oral candidiasis (OC) is a potential oral complication in Sjögren’s Syndrome (SS). Some studies indicate that the low stimulated salivary flow and not low unstimulated salivary flow is associated with OC in SS, while others report that the underlying autoimmune disorders contributes to OC, based solely on correlation coefficients. Given the conflicting and limited existing evidence, we purposed to ascertain the role of both salivary gland dysfunction (hyposalivation based on unstimulated and stimulated flow rates) and autoimmunity (SS, other autoimmune disorders) in OC among those with SS, other salivary gland dysfunction and non-salivary gland dysfunction controls (NSGD). Methods A nested case-control study was designed within a larger NIH/NIDCR cohort. Descriptive analyses, non-parametric tests, comparative analyses, and multivariate logistic regression analyses were undertaken. Results Data on 1,526 subjects (701 SS, 247 ISS, 355 Sicca, and 223 NSGD) were obtained from the source cohort of 2,046 and analyzed for this current study. The median whole unstimulated salivary flow rate (WUS, ml/15min) was lower in SS (0.8, interquartile range (IQR) 1.8) compared to ISS (5.5, IQR 5.2, pcandidiasis. Conclusion Salivary gland dysfunction (hyposalivation with WUS being a stronger predictor than TSS) and autoimmunity (SS, other autoimmune disorders, medications i.e., DMARDS) are both independent predictors of OC. Diabetes mellitus is an independent predictor of OC among those with salivary gland dysfunction. Our findings suggest that these independent predictors should be considered in the prevention and management of OC in this population. PMID:27998016

Full Text Available Celiac disease is an autoimmune systemic disorder. It presents gastrointestinal and nongastrointestinal manifestations as well as associated conditions. We report a 16-year-old Down syndrome girl who presented psychosis symptomatology, and she was diagnosed as having silent celiac disease. Olanzapine treatment and gluten-free diet were satisfactory. It is necessary to consider celiac disease in Down syndrome patients with psychiatric symptoms, mainly psychotic symptomatology.

2017-11-01

Antiphospholipid syndrome (APS) is an autoimmune disease characterized by antiphospholipid antibodies (aPL) associated with thrombosis and/or pregnancy morbidity. Most APS events are directly related to thrombotic events, which may affect small, medium or large vessels. Other clinical features like thrombocytopenia, nephropathy, cardiac valve disease, cognitive dysfunction and skin ulcers (called non-criteria manifestations) add significant morbidity to this syndrome and represent clinical situations that are challenging. APS was initially described in patients with systemic lupus erythematosus (SLE) but it can occur in patients without any other autoimmune disease. Despite the autoimmune nature of this syndrome, APS treatment is still based on anticoagulation and antiplatelet therapy.

2013-12-01

A 27-year-old male was admitted with diabetic ketoacidosis and altered sensorium with slurring of speech and ataxia. He was managed with intravenous insulin and fluids and later shifted to basal bolus insulin regimen and during further evaluation was diagnosed to be suffering from primary hypothyroidism and adrenal insufficiency. He was started on thyroxin replacement and steroids only during stress. After three months of follow up he was clinically euthyroid. His glycemic control was adequate on oral anti-hyperglycemic drugs and adrenal insufficiency recovered. However, his thyrotropin levels were persistently elevated on adequate replacement doses of thyroxin. His repeat TSH was estimated after precipitating serum with polyethylene glycol which revealed normal TSH. Here we report reversible adrenal insufficiency with hypothyroidism with falsely raised TSH because of presence of heterophile antibodies in a case of poly glandular endocrinopathy syndrome.

Paraneoplastic syndromes and autoimmune encephalitis

Rosenfeld, Myrna R.; Titulaer, Maarten J.

2012-01-01

Summary We review novel findings in paraneoplastic syndromes including the Lambert-Eaton myasthenic syndrome, and then focus on the novel disorders associated with antibodies against cell surface antigens, discussing the importance and caveats of antibody testing, and providing an algorithm for interpretation of results. In anti-NMDAR encephalitis 2 novel findings include the recognition of a characteristic EEG pattern (“extreme delta brush”) in 30% of patients and the demonstration of a fronto-temporo-occipital gradient of glucose metabolism that correlates with disease activity. In limbic encephalitis, antibodies to GABA(B) receptor are the most frequently detected in patients with small-cell lung cancer who are anti-Hu negative, and antibodies to mGluR5 distinctively associate with Hodgkin lymphoma (Ophelia syndrome). We also address the syndromes associated with “VGKC-complex antibodies,” a problematic term that groups well-characterized immune-mediated disorders (LGI1, Caspr2) with others that lack syndrome specificity, are less responsive to treatment, and for which the target antigens are unknown.

Raquel Souto-Rodríguez

Full Text Available Down's syndrome (DS is a genetic disease that has been associated with several immune and autoimmune diseases, including digestive and liver diseases, like celiac disease, autoimmune chronic hepatitis and sclerosing cholangitis. Despite in inflammatory bowel disease (IBD pathogenesis, genetics and immune mechanism play an important role, the association among DS and IBD has been poorly studied. Data about IBD diagnosis in DS patients is very scarce with only some individual case-reports. We report three cases of DS patients diagnosed of IBD and we discuss the possible association of these two entities.

Stiff person syndrome (SPS: Literature review and case report

2013-11-01

Full Text Available Stiff person syndrome (SPS is a rare, debilitating condition which presents with progressive and inconsistent neurological features. The main symptoms are stiffness and intermittent, painful muscle spasms, triggered and exacerbated by stressful and emotional stimuli. The fluctuating clinical nature of SPS, and otherwise normal neurological examination, often lead to a misdiagnosis of conversion disorder. Psychiatric symptoms frequently accompany this disorder and patients are often first seen by psychiatrists. SPS is autoimmune-based: antibodies are directed against glutamate decarboxylase, resulting in dysregulation of gamma-aminobutyric acid (GABA in the brain which is considered the cause of the neuropsychiatric symptomatology. SPS should be considered in the differential diagnosis of conversion disorder. Effective management requires early detection, a collaborative approach with GABA-ergic medication and intravenous immunoglobulins, and management of concomitant psychiatric disorders. We describe a patient with SPS. Only one other case has been reported in South Africa.

Zhiyuan Zhao

Full Text Available The prevalence of celiac disease autoimmunity or tissue transglutaminase autoantibodies (TGA amongst patients with type 1 diabetes (T1D and autoimmune thyroid disease (AITD in the Chinese population remains unknown. This study examined the rate of celiac disease autoimmunity amongst patients with T1D and AITD in the Chinese population. The study included 178 patients with type 1 diabetes and 119 with AITD where 36 had both T1D and AITD, classified as autoimmune polyglandular syndrome type 3 variant (APS3v. The study also included 145 patients with type 2 diabetes (T2D, 97 patients with non-autoimmune thyroid disease (NAITD, and 102 healthy controls. Serum islet autoantibodies, thyroid autoantibodies and TGA were measured by radioimmunoassay. TGA positivity was found in 22% of patients with either type 1 diabetes or AITD, much higher than that in patients with T2D (3.4%; p< 0.0001 or NAITD (3.1%; P < 0.0001 or healthy controls (1%; p<0.0001. The patients with APS3v having both T1D and AITD were 36% positive for TGA, significantly higher than patients with T1D alone (p = 0.040 or with AITD alone (p = 0.017. T1D and AITD were found to have a 20% and 30% frequency of overlap respectively at diagnosis. In conclusion, TGA positivity was high in the Chinese population having existing T1D and/or AITD, and even higher when both diseases were present. Routine TGA screening in patients with T1D or AITD will be important to early identify celiac disease autoimmunity for better clinical care of patients.

Among Western populations, the declining incidence of Helicobacter pylori infection coincides with a growing clinical impact of autoimmune gastritis. To describe the histological phenotype of autoimmune gastritis, also to test the prognostic impact of OLGA staging in the autoimmune setting. A single-institutional series (spanning the years 2003-2011) of 562 consecutive patients (M:F ratio: 1:3.7; mean age = 57.6 ± 14.4 years) with serologically confirmed autoimmune gastritis underwent histology review and OLGA staging. Helicobacter pylori infection was ascertained histologically in 44/562 cases (7.8%). Forty six biopsy sets (8.2%) featured OLGA stages III-IV; they included all four cases of incidental epithelial neoplasia (three intraepithelial and one invasive; three of these four cases had concomitant H. pylori infection). There were 230 (40.9%) and 139 (24.7%) cases, respectively, of linear and micro-nodular enterochromaffin-like cell hyperplasia; 19 (3.4%) type I carcinoids were detected. The series included 116 patients who underwent repeated endoscopy/biopsy sampling (mean time elapsing between the two procedures = 54 months; range 24-108). Paired histology showed a significant (P = 0.009) trend towards a stage progression [the stage increased in 25/116 cases (22%); it remained unchanged in 87/116 cases (75%)]. In autoimmune gastritis, the cancer risk is restricted to high-risk gastritis stages (III-IV), and is associated mainly with concomitant H. pylori infection. OLGA staging consistently depicts the time-dependent organic progression of the autoimmune disease and provides key information for secondary gastric cancer prevention strategies. © 2012 Blackwell Publishing Ltd.

A 33 year old female was admitted to the hospital to study aedema and bocio, A nephrotic syndrome was diagnosed and the renal biopsy demonstrated membranous glomerulonephritis, stage II. She was also diagnosed of Hashimoto's autoinmmune thyroiditis: TSH (41.5 uUl/ml), T4 (0.07 ng/dl), antithyroglobuline (1/2560) and antimicrosome (1/6400). Four year latter she was diagnosed of autoinmmune pancreatitis, without evidence of diabetes mellitus or exocrine pancreatic insufficiency. Eight years latter she was diagnosed of primary autoimmune suprarrenal insufficiency: basal cortisol: 2.7 mcg/dl, post ACTH estimulated cortisol: 5.6 mcg/dl, antinuclear antibody (1/160) and antiparietal (1/320). We present a pluriglandular autoimmune syndrome with membranous glomerulonephritis, thyroiditis, pancreatitis and suprarrenal insufficiency. To the best of our knowledge this complex syndrome has not been previously described.

Autoimmune connective tissue diseases and vaccination

Ewa Więsik-Szewczyk

2015-12-01

Full Text Available The idea that infectious agents can induce autoimmune diseases in genetically susceptible subjects has been a matter of discussion for years. Moreover, increased incidence of autoimmune diseases and introduction of prophylactic vaccinations from early childhood suggest that these two trends are linked. In the medical literature and even non-professional media, case reports or events temporally related to vaccination are reported. It raises the issue of vaccination safety. In everyday practice medical professionals, physicians, rheumatologists and other specialists will be asked their opinion of vaccination safety. The decision should be made according to evidence-based medicine and the current state of knowledge. The purpose of this paper is to discuss a potential mechanism which links infections, vaccinations and autoimmunity. We present an overview of published case reports, especially of systemic connective tissue diseases temporally related to vaccination and results from case-nested studies. As yet, no conclusive evidence supports a causal relationship between vaccination and autoimmune diseases. It has to be determined whether the performed studies are sufficiently Epsteinasensitive to detect the link. The debate is ongoing, and new data may be required to explain the pathogenesis of autoimmunity. We would like to underscore the need for prophylactic vaccination in patients with autoimmune rheumatic diseases and to break down the myth that the vaccines are contraindicated in this target group.

HTLV-1, Immune Response and Autoimmunity

Full Text Available Human T-lymphotropic virus type-1 (HTLV-1 infection is associated with adult T-cell leukemia/lymphoma (ATL. Tropical spastic paraparesis/HTLV-1-associated myelopathy (PET/HAM is involved in the development of autoimmune diseases including Rheumatoid Arthritis (RA, Systemic Lupus Erythematosus (SLE, and Sjögren’s Syndrome (SS. The development of HTLV-1-driven autoimmunity is hypothesized to rely on molecular mimicry, because virus-like particles can trigger an inflammatory response. However, HTLV-1 modifies the behavior of CD4+ T cells on infection and alters their cytokine production. A previous study showed that in patients infected with HTLV-1, the activity of regulatory CD4+ T cells and their consequent expression of inflammatory and anti-inflammatory cytokines are altered. In this review, we discuss the mechanisms underlying changes in cytokine release leading to the loss of tolerance and development of autoimmunity.

Autoimmune hepatitis in association with lymphocytic colitis.

LENUS (Irish Health Repository)

Cronin, Edmond M

2012-02-03

Autoimmune hepatitis is a rare, chronic inflammatory disorder which has been associated with a number of other auto-immune conditions. However, there are no reports in the medical literature of an association with microscopic (lymphocytic) colitis. We report the case of a 53-year-old woman with several autoimmune conditions, including lymphocytic colitis, who presented with an acute hepatitis. On the basis of the clinical features, serology, and histopathology, we diagnosed autoimmune hepatitis. To our knowledge, this is the first report of autoimmune hepatitis in association with lymphocytic colitis, and lends support to the theory of an autoimmune etiology for lymphocytic colitis.

Statin-Associated Autoimmune Myopathy: A Systematic Review of 100 Cases.

Statins are a group of drugs that reduce the levels of triglycerides and cholesterol in blood by inhibiting HMG-CoA reductase, an enzyme involved in rate limiting step in cholesterol synthesis. About 2-20% patients on statins develop toxic myopathies, which usually resolve on discontinuation of statin. More recently, an immune-mediated necrotizing myopathy has been found to be associated with statin use which in most cases requires treatment with immunosuppressants. To perform a systematic review on published case reports and case series of statin-associated autoimmune myopathy. A comprehensive search of PUBMED, EMBASE, Cochrane library and ClinicalTrials.gov databases was performed for relevant articles from inception until March 19, 2016 to identify cases of statin-associated necrotizing myopathy and characterize their symptoms, evaluation and response to treatment. A total of 16 articles describing 100 patients with statin-associated autoimmune myopathy were identified. The mean age of presentation was 64.72 years, and 54.44% were males. The main presenting clinical feature was proximal muscle weakness, which was symmetric in 83.33% of patients. The mean creatine kinase (CK) was 6853 IU/l. Anti-HMG-CoA reductase antibody was positive in all cases tested (n = 57/57, 100%). In patients with no anti-HMG-CoA antibody results, diagnosis was established by findings of necrotizing myopathy on biopsy. Among the 83 cases where muscle biopsy information was available, 81.48% had necrosis, while 18.51% had combination of necrosis and inflammation. Most (83.82%) patients received two or more immunosuppressants to induce remission. Ninety-one percent had resolution of symptoms after treatment. Statin-associated necrotizing myopathy is a symmetric proximal muscle weakness associated with extreme elevations of CK. It is common in males and can occur after months of statin use. It is associated with necrosis on muscle biopsy and the presence of anti-HMG-CoA reductase antibodies

Saccharomyces cerevisiae is best known as the baker's and brewer's yeast, but its residual traces are also frequent excipients in some vaccines. Although anti-S. cerevisiae autoantibodies (ASCAs) are considered specific for Crohn's disease, a growing number of studies have detected high levels of ASCAs in patients affected with autoimmune diseases as compared with healthy controls, including antiphospholipid syndrome, systemic lupus erythematosus, type 1 diabetes mellitus, and rheumatoid arthritis. Commensal microorganisms such as Saccharomyces are required for nutrition, proper development of Peyer's aggregated lymphoid tissue, and tissue healing. However, even the commensal nonclassically pathogenic microbiota can trigger autoimmunity when fine regulation of immune tolerance does not work properly. For our purposes, the protein database of the National Center for Biotechnology Information (NCBI) was consulted, comparing Saccharomyces mannan to several molecules with a pathogenetic role in autoimmune diseases. Thanks to the NCBI bioinformation technology tool, several overlaps in molecular structures (50-100 %) were identified when yeast mannan, and the most common autoantigens were compared. The autoantigen U2 snRNP B″ was found to conserve a superfamily protein domain that shares 83 % of the S. cerevisiae mannan sequence. Furthermore, ASCAs may be present years before the diagnosis of some associated autoimmune diseases as they were retrospectively found in the preserved blood samples of soldiers who became affected by Crohn's disease years later. Our results strongly suggest that ASCAs' role in clinical practice should be better addressed in order to evaluate their predictive or prognostic relevance.

Development of central nervous system autoimmunity is impaired in the absence of Wiskott-Aldrich syndrome protein.

Full Text Available Wiskott-Aldrich Syndrome protein (WASP is a key regulator of the actin cytoskeleton in hematopoietic cells. Defective expression of WASP leads to multiple abnormalities in different hematopoietic cells. Despite severe impairment of T cell function, WAS patients exhibit a high prevalence of autoimmune disorders. We attempted to induce EAE, an animal model of organ-specific autoimmunity affecting the CNS that mimics human MS, in Was(-/- mice. We describe here that Was(-/- mice are markedly resistant against EAE, showing lower incidence and milder score, reduced CNS inflammation and demyelination as compared to WT mice. Microglia was only poorly activated in Was(-/- mice. Antigen-induced T-cell proliferation, Th-1 and -17 cytokine production and integrin-dependent adhesion were increased in Was(-/- mice. However, adoptive transfer of MOG-activated T cells from Was(-/- mice in WT mice failed to induce EAE. Was(-/- mice were resistant against EAE also when induced by adoptive transfer of MOG-activated T cells from WT mice. Was(+/- heterozygous mice developed an intermediate clinical phenotype between WT and Was(-/- mice, and they displayed a mixed population of WASP-positive and -negative T cells in the periphery but not in their CNS parenchyma, where the large majority of inflammatory cells expressed WASP. In conclusion, in absence of WASP, T-cell responses against a CNS autoantigen are increased, but the ability of autoreactive T cells to induce CNS autoimmunity is impaired, most probably because of an inefficient T-cell transmigration into the CNS and defective CNS resident microglial function.

Chronic fatigue syndrome (CFS) is a heterogeneous disease which presents with pronounced disabling fatigue, sleep disturbances, and cognitive impairment that negatively affects patients' functional capability. CFS remains a poorly defined entity and its etiology is still in question. CFS is neither a novel diagnosis nor a new medical condition. From as early as the eighteenth century, a constellation of perplexing symptoms was observed that resembled symptoms of CFS. Commencing with "febricula" and ending with CFS, many names for the disease were proposed including neurocirculatory asthenia, atypical poliomyelitis, Royal Free disease, effort syndrome, Akureyri disease, Tapanui disease, chronic Epstein-Barr virus syndrome, and myalgic encephalitis. To date, it remains unclear whether CFS has an autoimmune component or is a condition that precedes a full-blown autoimmune disease. Research suggests that CFS may overlap with other diseases including postural orthostatic tachycardia syndrome (POTS), autoimmune syndrome induced by adjuvants (ASIA), and Sjögren's syndrome. Additionally, it has been postulated that the earliest manifestations of some autoimmune diseases can present with vague non-specific symptoms similar to CFS. Sometimes only when exposed to a secondary stimulus (e.g., antigen) which could accelerate the natural course of the disease would an individual develop the classic autoimmune disease. Due to the similarity of symptoms, it has been postulated that CFS could simply be an early manifestation of an autoimmune disease. This paper will provide a historical background review of this disease and a discussion of CFS as an entity overlapping with multiple other conditions.

Full Text Available The first clinical cases of obsessive-compulsive di­sorder and/or tic disorder in children with acute sudden onset associated with infectious diseases have been named pediatric infection-triggered autoimmune neuropsychiatric disorders (PITANDS. The relationship of such neuropsychiatric manifestations with preceding infectious diseases caused by group A beta-hemolytic Streptococcus was the most important, and it has been called paediatric autoimmune neuropsychiatric disorder associated with streptococcal infection (PANDAS. Due to the low level of evidence of the research on the relationship of infectious agents with neurological and behavioral symptoms with an acute onset, since 2014 another syndrome is diagnosed in children — pediatric acute-onset neuropsychiatric syndrome (PANS. Currently, the question about infectious etiology, pathogenesis and autoimmune mechanisms of these paediatric neuropsychiatric syndromes are still debatable.

Abstract Macrophage activation syndrome (MAS) is a severe and potentially fatal life-threatening condition associated with excessive activation and expansion of T cells with macrophages and a high expression of cytokines, resulting in an uncontrolled inflammatory response, with high levels of macrophage colony-stimulating factor and causing multiorgan damage. This syndrome is classified into primary (genetic/familial) or secondary forms to several etiologies, such as infections, neoplasias mainly hemopathies or autoimmune diseases. It is characterised clinically by unremitting high fever, pancytopaenia, hepatosplenomegaly, hepatic dysfunction, encephalopathy, coagulation abnormalities and sharply increased levels of ferritin. The pathognomonic feature of the syndrome is seen on bone marrow examination, which frequently, though not always, reveals numerous morphologically benign macrophages exhibiting haemophagocytic activity. Because MAS can follow a rapidly fatal course, prompt recognition of its clinical and laboratory features and immediate therapeutic intervention are essential. However, it is difficult to distinguish underlying disease flare, infectious complications or medication side effects from MAS. Although, the pathogenesis of MAS is unclear, the hallmark of the syndrome is an uncontrolled activation and proliferation of T lymphocytes and macrophages, leading to massive hypersecretion of pro-inflammatory cytokines. Mutations in cytolytic pathway genes are increasingly being recognised in children who develop MAS in his secondary form. We present here a case of Macrophage activation syndrome associated with Griscelli syndrome type 2 in a 3-years-old boy who had been referred due to severe sepsis with non-remitting high fever, generalized lymphoadenopathy and hepato-splenomegaly. Laboratory data revealed pancytopenia with high concentrations of triglycerides, ferritin and lactic dehydrogenase while the bone marrow revealed numerous morphologically benign

Bickerstaff’s brainstem encephalitis, Miller Fisher syndrome and Guillain-Barré syndrome overlap in an asthma patient with negative anti-ganglioside antibodies

Full Text Available Abstract Background Bickerstaff’s brainstem encephalitis (BBE, together with Miller Fisher syndrome (MFS and Guillain-Barré syndrome (GBS were considered to form a continuous clinical spectrum. An anti-GQ1b antibody syndrome has been proposed to underlie the common pathophysiology for the three disorders; however, other studies have found a positive anti-GM1 instead of anti-GQ1b antibody. Case presentation Here we report a 20-year-old male patient with overlapping BBE, MFS and GBS. The patient had a positive family history of bronchial asthma and had suffered from the condition for over 15 years. He developed BBE symptoms nine days after an asthma exacerbation. During the course of illness, he had significantly elevated IgE levels in both serum and cerebrospinal fluid. Serologic analysis of antibodies against ganglioside complexes (anti-GDIa, anti-GDIb, anti-GM1, anti-GM2, anti-GM3, anti-GQIb and anti-GTIb antibodies showed negative results. Conclusions Since asthma has recently been related to autoimmune disease, our case supports an autoimmune mechanism underlying the clinical spectrum composed of BBE, MFS and GBS. However, contrary to a proposed anti-GQ1b antibody syndrome, we would suggest that pathogenesis of this clinical spectrum is not limited to anti-ganglioside antibodies.

2012-11-01

Full Text Available Abstract Introduction Optic neuritis, although uncommon, can be the initial presentation of Sjögren’s syndrome. Coexisting Sjögren’s syndrome has also been reported with neuromyelitis optica spectrum disorder. This case report highlights the association between the two diseases and the importance of rheumatological and neurological evaluations in patients with such diagnoses. Distinction of neuromyelitis optica with coexisting connective tissue disease has both prognostic and therapeutic significance for the patient. Case presentation We report a case of a 56-year-old Chinese woman who presented with bilateral asymmetric visual loss secondary to optic neuritis. She was subsequently found to be seropositive for neuromyelitis optica immunoglobulin G (NMO-IgG (anti-aquaporin-4 antibody and was diagnosed with neuromyelitis optica spectrum disorder. She also fulfilled the international criteria for Sjögren’s syndrome. Despite initial high dose immunosuppressive therapy, she failed to regain vision in one eye. Conclusion Patients presenting with optic neuritis and severe visual loss should be screened for neuromyelitis optica and treated appropriately. Neuromyelitis optica has been associated with systemic autoimmune diseases, in particular Sjögren’s syndrome, and current evidence indicates that they are two distinct entities. We recommend that both diagnoses be considered in cases of optic neuritis with severe visual loss.

Human T lymphotropic virus type 1 (HTLV-1) infection with high prevalence in the north-east of Iran, particularly in Mashhad, can lead to adult T-cell leukemia (ATL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) and a variety of autoimmune diseases. The aim of the study was to examine the presence of autoimmune markers in HTLV carries. Serum samples were obtained from blood donors in Mashhad, northeastern Iran. One hundred and five HTLV-1 positive (cases) and 104 age- and sex-matched HTLV-1 negative donors (controls) were assessed for presence of serum autoimmune markers by enzyme-linked immunosorbent assay. The mean ages of cases and controls were 40.8 ± 9.4 and 41.5 ± 9.3 years, respectively (P = 0.5). In the case group, 81.9% and in the control group 83.7% were male (P = 0.74). The frequency of positive antinuclear antibodies and anticyclic citrullinated peptide antibodies in the serum of the two groups were not significantly different (P = 0.68 and P = 0.62, respectively). Only one antineutrophil cytoplasmic antibody-positive case (1%) was observed in the group and no anti-phospholipid immunoglobulin G positivity was observed. The frequency of rheumatoid factor (RF) was greater in case group than in the control group, although the difference was not significant (P = 0.08). The amount of RF in all 12 RF positive sera were higher than normal levels (33-37 IU/mL). Because we failed to detect any significant relation between serum autoimmune markers and HTLV-1 infection, and because of the relatively low prevalence of autoimmune diseases, it could be concluded that healthy HTLV-1 carriers do not produce rheumatologic-related auto-antibodies more than the healthy population. © 2017 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

Full Text Available Moyamoya (MMD is a disease that often involves the vascular structures of anterior cerebral circulation, particularly the proximal segments of anterior and middle cerebral arteries. The etiology of the disease is unknown. MMD often presents with cerebral ischemia and rarely with cerebral hemorrhage. The pathology is termed Moyamoya syndrome (MMS when the pathological cerebral angiography findings are accompanied by meningitis, neurofibromatosis, neoplasm, Down syndrome or polycystic kidney disease. Autoimmune diseases including Graves’ disease, Behcet’s disease and antiphospholipid syndrome might also lead to the development of MMS. In this manuscript, we presented an interesting case of MMD associated with antiphospholipid syndrome, which is quite a rare cause of acute cerebral infarction in childhood

A case report and literature review is presented. To review relevant data for the management of Bertolotti's syndrome and to determine whether the transverse process-ilium articulation may be a pain generator. Bertolotti's syndrome is associated with axial low back pain secondary to arthritic changes; the pain generator in the disorder is unclear. We present a case report of symptomatic Bertolotti's syndrome managed with intra-articular steroid injections. A patient with Bertolotti's syndrome had significant relief of axial pain after steroid injection of the ilium-transverse process articulation. Steroid therapy may be a non-surgical alternative for the treatment of symptomatic Bertolotti's syndrome.

We report the case of a 27-year-old lady presenting with painful swelling of predominantly lower limbs with extensive vesicles and ecchymotic patches and fever shortly after stopping systemic steroids taken for a prolonged duration (2002--2010. The aim of this case report is to point to the possibility of CSS in patients presenting with extensive skin lesions masquerading as Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis Syndrome (SJS/TENS.

A new animal model of spontaneous autoimmune peripheral polyneuropathy: implications for Guillain-Barré syndrome.

Spontaneous autoimmune peripheral neuropathy including Guillain-Barré Syndrome (GBS) represents as one of the serious emergencies in neurology. Although pathological changes have been well documented, molecular and cellular mechanisms of GBS are still under-explored, partially due to short of appropriate animal models. The field lacks of spontaneous and translatable models for mechanistic investigations. As GBS is preceded often by viral or bacterial infection, a condition can enhance co-stimulatory activity; we sought to investigate the critical role of T cell co-stimulation in this autoimmune disease. Our previous study reported that transgene-derived constitutive expression of co-stimulator B7.2 on antigen presenting cells of the nervous tissues drove spontaneous neurological disorders. Depletion of CD4+ T cells in L31 mice accelerated the onset and increased the prevalence of the disease. In the current study, we further demonstrated that L31/CD4-/- mice exhibited both motor and sensory deficits, including weakness and paresis of limbs, numbness to mechanical stimuli and hypersensitivity to thermal stimulation. Pathological changes were characterized by massive infiltration of macrophages and CD8+ T cells, demyelination and axonal damage in peripheral nerves, while changes in spinal cords could be secondary to the PNS damage. In symptomatic L31/CD4-/- mice, the disruption of the blood neural barriers was observed mainly in peripheral nerves. Interestingly, the infiltration of immune cells was initiated in pre-symptomatic L31/CD4-/- mice, prior to the disease onset, in the DRG and spinal roots where the blood nerve barrier is virtually absent. L31/CD4-/- mice mimic most parts of clinical and pathological signatures of GBS in human; thus providing an unconventional opportunity to experimentally explore the critical events that lead to spontaneous, autoimmune demyelinating disease of the peripheral nervous system.

We report a case of laryngeal edema associated with the Vogt-Koyanagi-Harada (VKH) syndrome. A 32-year-old African-American female presented with a 12-day prodrome, including headache, tinnitus and shortness of breath, which preceded sudden photophobia and bilateral visual loss. Examination and clinical testing were most consistent with VKH, and the patient improved with intravenous methylprednisolone therapy. The patient had persistent dyspnea, which was out of proportion to chest CT findings and which was exacerbated during a recurrence of VKH. Flexible fiberoptic laryngoscopy with stroboscopy revealed diffuse laryngeal edema. Symptoms were alleviated with breathing exercises. Several autoimmune diseases may cause diffuse laryngeal edema. In this case, VKH was associated with the patient's glottic edema and dyspnea. We recommend that laryngeal edema be considered in the differential diagnosis for patients with dyspnea and VKH.

Western countries are seeing a constant decline in the incidence of Helicobacter pylori-associated gastritis, coupled with a rising epidemiological and clinical impact of autoimmune gastritis. This latter gastropathy is due to autoimmune aggression targeting parietal cells through a complex interaction of auto-antibodies against the parietal cell proton pump and intrinsic factor, and sensitized T cells. Given the specific target of this aggression, autoimmune gastritis is typically restricted to the gastric corpus-fundus mucosa. In advanced cases, the oxyntic epithelia are replaced by atrophic (and metaplastic) mucosa, creating the phenotypic background in which both gastric neuroendocrine tumors and (intestinal-type) adenocarcinomas may develop. Despite improvements in our understanding of the phenotypic changes or cascades occurring in this autoimmune setting, no reliable biomarkers are available for identifying patients at higher risk of developing a gastric neoplasm. The standardization of autoimmune gastritis histology reports and classifications in diagnostic practice is a prerequisite for implementing definitive secondary prevention strategies based on multidisciplinary diagnostic approaches integrating endoscopy, serology, histology and molecular profiling.

CLINICAL SIGNIFICANCE OF IMMUNE IMBALANCE AND AUTOIMMUNITY IN NERVOUS SYSTEM DISORDERS (NSDs

Directory of Open Access Journals (Sweden)

Vijendra K. SINGH

2015-11-01

Full Text Available In recent years, the role of immune imbalance and autoimmunity has been experimentally demonstrated in nervous system disorders (NSDs that include Alzheimer’s disease, autism, obsessive-compulsive disorder (OCD, tics and Tourette’s syndrome, schizophrenia, and some other NSDs. And yet, these NSDs are never counted as autoimmune diseases. Deriving from the rapidly expanding knowledge of neuro-immunology and auto-immune diseases, for example multiple scle-rosis (MS, the author of this mini-review strongly recommends that these NSDs should be included while tallying the number of autoimmune diseases. This effort will help create an updated global database of all autoimmune diseases as well as it should help treat millions of patients who are suffering from debilitating NSDs for which there is no known cure or treatment currently.

2012-01-01

Full Text Available Sjogren’s syndrome is a slowly progressive autoimmune disease. Neurological involvement occurs in approximately 20-25% cases in Sjogren’s syndrome. 87% of the neurological involvement is peripheral nervous system, almost 13% in the form of central nervous system involvement. Affected central nervous system may show similar clinical and radiological findings as in multiple sclerosis (MS. In this paper, a 43-year-old patient is discussed who was referred with the complaint of dizziness, there was MS- like lesions in brain imaging studies and was diagnosed with Sjogren’s syndrome. MS- like clinical and radiologic tables can be seen, albeit rarely in Sjogren’s syndrome. In these cases, early diagnosis and early treatment for the sjögren has a great importance for the prognosis of the disease.

Addison's disease is an autoimmune process. However, Addison's disease associated with connective tissue diseases (CTD) is only occasionally reported. Here, we report six cases of Addison's disease secondary to a variety of CTD, which include systemic lupus erythematosus, Takayasu arteritis, systemic sclerosis, ankylosing spondylitis (AS) and antiphospholipid antibody syndrome. The association of Addison's disease with Takayasu arteritis and AS is reported for the first time. We also found high prevalence of hypothyroidism as concomitant autoimmune disorder. Our case series highlight the autoimmune features of Addison's disease. Therefore, we suggest considering adrenal dysfunction in patients with CTD.

Vitiligo is a chronic disease characterized by the dysfunction or destruction of melanocytes with secondary depigmentation. The aim of the present study was to determine the prevalence of vitiligo associated with autoimmune rheumatic diseases. The clinical records from a 10-year database of patients with rheumatic diseases and associated vitiligo was analysed, with one group of patients having autoimmune rheumatic disease and another non-autoimmune rheumatic disease. Available serum samples were used to assess the anti-melanocyte antibodies. A total of 5,251 individual clinical files were archived in the last 10 years, and these patients underwent multiple rheumatology consultations, with 0.3% of the group presenting with vitiligo. The prevalence of vitiligo in the autoimmune rheumatic disease group was 0.672%, which was mainly associated with lupus and arthritis. However, patients with more than one autoimmune disease had an increased relative risk to develop vitiligo, and anti-melanocyte antibodies were positive in 92% of these patients. By contrast, the prevalence was 0.082% in the group that lacked autoimmune rheumatic disease and had negative autoantibodies. In conclusion, the association between vitiligo and autoimmune rheumatic diseases was relatively low. However, the relative risk increased when there were other autoimmune comorbidities, such as thyroiditis or celiac disease. Therefore, the presence of multiple autoimmune syndromes should be suspected.

AIM: To describe the outcome and prognosis in a cohort of patients with acute liver failure due to autoimmune hepatitis without liver transplantation. METHODS: A retrospective trial was conducted in 11 patients with acute liver failure due to autoimmune hepatitis who attended the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubiran. Demographic, biochemical and severity indexes, and treatment and outcome were assessed. RESULTS: Among the 11 patients, with a median age of 31 years, 72% had inflammatory response syndrome, and six patients received corticosteroids. The mortality rate within four weeks was 56%, and the one-year survival was 27%. In the survivors, severity indexes were lower and 83% received corticosteroids. CONCLUSION: We observed a relatively high survival rate in patients with acute liver failure due to autoimmune hepatitis. This survival rate could be influenced by severity of the disease and/or use of corticosteroids. PMID:17465474

Full Text Available We report four adult cases of atopic dermatitis (AD complicated by Sjogren's syndrome (SS. The patients fulfilled diagnostic criteria for AD and SS. All cases showed persistent itchy dry skin and eczematous lesions complicated by sicca symptoms including dry eyes and dry mouth with moderate joint pain. One case manifested annular erythema and another manifested widespread discoid erythema. To investigate the underlying cause of dry skin in these cases, sweating function was evaluated using a quantitative sudomotor axon reflex test (QSART in which the axon reflex is stimulated by acetylcholine iontophoresis. The sweating latency time was significantly prolonged in eczematous skin of AD and AD/SS compared to normal controls. Axon reflex (AXR sweat volume was also significantly reduced in AD (normal and eczematous skin and AD/SS (normal and eczema compared to normal control. In contrast, the direct sweat volume of lesional or non-lesional AD skin induced by direct stimulation with acetylcholine was only slightly reduced compared to that in normal controls, but not in SS and lesional skin of AD/SS patients. These results suggest that the impaired sweat response in AD is attributable to an abnormal sudomotor axon reflex, which is accelerated and modulated when complicated by SS resulting in dry skin in the present cases.

Full Text Available Autoimmune polyendocrine syndrome type 1 (APS-1 is a rare autosomal recessive disease defined by the presence of two of the three conditions: mucocutaneous candidiasis, hypoparathyroidism, and Addison's disease. Loss-of-function mutations of the autoimmune regulator (AIRE gene have been linked to APS-1. Here we report mutational analysis and functional characterization of an AIRE mutation in a consanguineous Chinese family with APS-1. All exons of the AIRE gene and adjacent exon-intron sequences were amplified by PCR and subsequently sequenced. We identified a homozygous missense AIRE mutation c.463G>A (p.Gly155Ser in two siblings with different clinical features of APS-1. In silico splice-site prediction and minigene analysis were carried out to study the potential pathological consequence. Minigene splicing analysis and subsequent cDNA sequencing revealed that the AIRE mutation potentially compromised the recognition of the splice donor of intron 3, causing alternative pre-mRNA splicing by intron 3 retention. Furthermore, the aberrant AIRE transcript was identified in a heterozygous carrier of the c.463G>A mutation. The aberrant intron 3-retaining transcript generated a truncated protein (p.G155fsX203 containing the first 154 AIRE amino acids and followed by 48 aberrant amino acids. Therefore, our study represents the first functional characterization of the alternatively spliced AIRE mutation that may explain the pathogenetic role in APS-1.

TSH Isoforms: About a Case of Hypothyroidism in a Down's Syndrome Young Adult

Full Text Available Background. For unknown reasons, the prevalence of thyroid autoimmune disorders is higher in patients with Down's syndrome than in the general population. The present case strongly supports a recent evaluation of propagating screening for thyroid disease in this group of patients to assure early diagnosis of hypothyroidism. Methods. In a 25-year-old man diagnosed with Down's syndrome, clinical manifestations of hypothyroidism were lacking, but profound biochemical abnormalities were found with particularly high levels of thyroid stimulating hormone (TSH. Antigenic properties of TSH were characterized using a panel of anti-TSH antibodies. Results. Technical problems not infrequently associated with TSH measurements are convincingly ruled out. Antigenic characterization of the patient's circulating TSH revealed circulating forms of TSH different from pituitary TSH which closely resembled TSH recombinant human hormone. Conclusions. It appears counterintuitive that the bioactivity of TSH decreases in the hypothyroid state as higher bioactivity of TSH is anticipated in hypothyroidism promoted by an increased hypothalamic TRH drive. In contrast, diminished negative thyroid hormone feedback will enhance posttranslational glycosylation of TSH subunits and increase sialylation of the carbohydrate side chains. Both exert a negative effect on TSH bioactivity, only compensated by the very high levels of the hormone as in the present case.

Full Text Available Chronic periaortitis (CP is a rare fibro-inflammatory disease characterized by periaortic fibrosis and/or aortic aneurysms formation, mostly localized in retroperitoneum and occasionally in the mediastinum. Recent studies have shown its common association with autoimmune diseases, therefore autoimmunity has been proposed as a contributing factor. Herein, we describe the second case in the literature of CP associated with antiphospholipid syndrome. A 64-year-old man with history of open surgery for inflammatory thoracic aneurysm and recurrent deep vein thrombosis was referred for abdominal pain and weight loss in the last 6 months. Further investigation revealed elevated acute-phase reactant levels, positive antiphospholipid autoantibodies, radiological and histological evidence of periaortic fibrosis and inflammation causing abdominal aneurysm and ureteral obstruction. Diagnosis of CP and antiphospholipid syndrome were made and steroid therapy was implemented with clinical and radiological improvement. The present report further supports the potentially immune-mediated origin of CP, highlighting its possible linkage with antiphospholipid syndrome.

To describe a case of retinal phlebitis associated with autoimmune hemolytic anemia. Observational case report. A 44-year-old Indian man diagnosed with autoimmune hemolytic anemia presented with a 1-week history of blurred vision in both eyes. Fundus biomicroscopy revealed bilateral peripheral retinal venous sheathing and cellophane maculopathy. Fundus fluorescent angiogram showed bilateral late leakage from the peripheral venous arcades and submacular fluid accumulation. The retinal phlebitis resolved following a blood transfusion and administration of systemic steroids. Retinopathy associated with autoimmune hemolytic anemia is not well known. This is thought to be the first documentation of retinal phlebitis occurring in this condition.

Full Text Available Goodpasture syndrome is a rare autoimmune disease, with significant morbidity and mortality in young people and otherwise healthy population. Complete disease remission is possible with prompt diagnosis and treatment. We report 3 cases with Goodpasture syndrome treated at the Department of Nephrology, University Clinic of Nephrology, with different outcome. All of the patients were with similar clinical feature, with renal failure that needed treatment with hemodialysis. But results of the treatment with plasmapheresis indicate that this procedure reduces morbidity in patients with Goodpasture syndrome. The clinical course and the outcome of the disease were different. The disease is unpredictable, and the early diagnosis and start with the treatment is important for the remission.

Autoimmune Addison's disease (AAD) is often associated with other components in autoimmune polyendocrine syndromes (APS). Whereas APS I is caused by mutations in the AIRE gene, the susceptibility genes for AAD and APS II are unclear. In the present study, we investigated whether polymorphisms or copy number variations in the AIRE gene were associated with AAD and APS II. First, nine SNPs in the AIRE gene were analyzed in 311 patients with AAD and APS II and 521 healthy controls, identifying no associated risk. Second, in a subgroup of 25 of these patients, AIRE sequencing revealed three novel polymorphisms. Finally, the AIRE copy number was determined by duplex quantitative PCR in 14 patients with APS I, 161 patients with AAD and APS II and in 39 healthy subjects. In two Scandinavian APS I patients previously reported to be homozygous for common AIRE mutations, we identified large deletions of the AIRE gene covering at least exon 2 to exon 8. We conclude that polymorphisms in the AIRE gene are not associated with AAD and APS II. We further suggest that DNA analysis of the parents of patients found to be homozygous for mutations in AIRE, always should be performed.

Transplantation of autoimmune potential. IV. Reversal of the NZB autoimmune syndrome by bone marrow transplantation

International Nuclear Information System (INIS)

Morton, J.I.; Siegel, B.V.

1979-01-01

The results of the present experiments support the concept of an etiology of autoimmune disease predicated upon innate properties of the hemopoietic stem cell and its differentiated lymphocytic progeny, independent of the host internal environment. It was concluded earlier that the NZB mouse strain possessed an enlarged compartment of cyclically active stem cells, providing an etiological basis for the development of autoimmune disease. Conceivably, a rapidly cycling stem cell population could randomly generate excessive numbers of lymphocytic progeny. Autoantibody formation would represent, then, a manifestation of the consequent hyperresponsiveness to immunological stimuli, both foreign and autologous. Alternatively, there may exist a parallel defect in the homeostatic regulation of both stem cell and immunocyte populations, attributable to either a defect in a shared regulator mechanism or to an unusually high threshold of these cells in response to negative feedback signals

infiltration and destruction) and/or lesions suggesting chronic cholangitis as well (bile duct paucity and/or proliferation, periductal sclerosis). Small bile ducts damage may be associated, at onset or in the following years, with lesions of larger bile ducts with duct wall irregularities, strictures, dilations, and beading resulting in the characteristic ''bead-on-a-string'' appearance. The ''small duct'' (autoimmune) sclerosing cholangitis is also called autoimmune cholangitis. PSC is strictly associated to a particular form of inflammatory bowel disease (IBD) which shows features not typical of ulcerative colitis neither of Crohn's disease. Symptoms related to IBD often are present at onset (abdominal pain, weight loss, bloody stools) but the liver disease is frequently asymptomatic and it may be discovered fortuitously. Treatment of PSC is particularly challenging. In case of ''small duct'' SC or in case of evidence active inflammation on liver biopsy, immunosuppressive treatment is probably useful while in case of large bile ducts non inflammatory sclerosis, immunosuppression is probably uneffective. Ursodeoxycholic acid, however, may leads to an improvement of liver biochemistry even if there's no evidence that it may alter the course of disease. Thus, liver transplantation, is often necessary in the long term follow-up, even with a risk of disease recurrence. In adjunction to these two main disorders, many patients show an''overlap'' disease with features of both AIH and PSC. In such disorders the immune-mediated damage concerns both the hepatocyte and the cholangiocyte with a continuous clinical spectrum from AIH with minimal bile ducts lesions and PSC with portal inflammation and active inflammatory liver damage.

Turner syndrome (TS) is one of the most common sexual chromosome abnormalities and is clearly associated with an increased risk of autoimmune diseases, particularly thyroid disease and coeliac disease (CD). Single-nucleotide polymorphism analyses have been shown to provide correlative evidence that specific genes are associated with autoimmune disease. Our aim was to study the functional polymorphic variants of PTPN22 and ZFAT in relation to thyroid disease and those of MYO9B in relation to CD. A cross-sectional comparative analysis was performed on Mexican mestizo patients with TS and age-matched healthy females. Our data showed that PTPN22 C1858T (considered a risk variant) is not associated with TS (X 2  = 3.50, p = .61, and OR = 0.33 [95% CI = 0.10-1.10]). Also, ZFAT was not associated with TS (X 2  = 1.2, p = .28, and OR = 1.22 [95% CI = 0.84-1.79]). However, for the first time, rs2305767 MYO9B was revealed to have a strong association with TS (X 2  = 58.6, p = .0001, and OR = 10.44 [95% C = 5.51-19.80]), supporting a high level of predisposition to CD among TS patients. This report addresses additional data regarding the polymorphic variants associated with autoimmune disease, one of the most common complications in TS. © 2017 John Wiley & Sons Ltd.

Churg-Strauss syndrome (CSS) is a systemic inflammatory disorder characterized by asthma, transient pulmonary infiltration, hyper-eosinophilia, and systemic vasculitis. Reported triggering factors include infections, drugs, allergic desensitization, and vaccinations, although cases involving the latter two are extremely rare. Herein, we describe a patient who developed CSS after receiving an H1N1 vaccination. A 55-year-old woman presented with fever, skin eruptions, and sensory impairment of her feet within one week after an H1N1 vaccine injection. A chest X-ray showed pulmonary infiltrations in both lower lung fields. Eosinophilia was noted in a hematological test, and an electrophysiological study revealed a pattern of mononeuritis multiplex. A skin biopsy was performed which revealed palisading necrotizing granuloma around a degenerated dermis and eosinophilic infiltration of the blood vessel walls. These findings combined with the hematological and electrophysiological findings met the criteria of CSS according to the American College of Rheumatology. The patient recovered well after steroid treatment. This case highlights the possibility that the H1N1 vaccination can trigger CSS. Due to the rarity of reported autoimmune events after vaccine administration and the obscure causal association between autoimmunity and a vaccine, further post-marketing surveillance and research are necessary to clarify the relationship and identify risk factors.

A 14-year-old female came with the history of sudden onset weakness; during work up, she was found to have hyperchloremic metabolic acidosis with normal anion gap and normal renal function suggesting the possibility of renal tubular acidosis (RTA). On further evaluation of RTA, she had positive antinuclear antibody, anti-Ro, and anti-La antibodies. On nuclear scan of salivary glands, her left parotid gland was nonfunctional. Her parotid biopsy revealed dilated interlobular ducts engulfed by lymphoid cells. She also had autoimmune hypothyroidism as suggested by raised TSH and positive anti-TPO antibodies. At admission, her serum potassium levels were low and she was treated with intravenous potassium chloride. After she recovered from acute hypokalemic paralysis, she was started on oral potassium citrate along with phosphate supplements, hydroxychloroquine, oral prednisolone and thyroxine supplements. Over the next 6 months, she has significant reduction in the dosage of potassium, bicarbonate and phosphate and gained 3 kg of weight and 3.5 cm of height. As primary Sjogren syndrome itself is rare in pediatric population and its association with renal tubular acidosis is even rarer, we suggest considering Sjogren syndrome as a differential diagnosis during the RTA work-up is worth trying.

Sjögren's syndrome (SS) is a systemic autoimmune disease characterized by the infiltration of lymphocytes in exocrine glands, specifically the salivary and lacrimal glands, resulting in the typical symptoms of xerophthalmia and xerostomia. SS may be accompanied by pleural effusion when the lung is involved, but this occurrence has been reported in only 10 cases in the literature. We report the case of a 42 year-old woman with severe bilateral pleural effusion for eight years. Primary Sjögren's Syndrome was finally diagnosed based on the presence of xerophthalmia and xerostomia, biopsy of the minor salivary glands, and positive anti-SS-A antibody in the serum and pleural effusion. Biopsy of the parietal pleura through video-assisted thoracoscopy revealed infiltration of lymphocytes. The patient had a long history of pleural effusion without clear etiology. Malignant disease was first suspected because of abnormal density lesion on the left lung and malignant cells found on cytology, but PET-CT revealed no malignant lesion. Examinations did not support infection, malignant tumor, pulmonary sarcoidosis, or other connective tissue diseases. This data could be useful for the future study of pleural effusion in SS.

Coagulopathy triggered autoimmunity: experimental antiphospholipid syndrome in factor V Leiden mice

Science.gov (United States)

2013-01-01

Background We investigated interactions between genetically and autoimmune-mediated coagulopathies by inducing experimental antiphospholipid syndrome (eAPS) in mice carrying the factor V Leiden (FVL) mutation. Methods eAPS was induced in heterozygous and homozygous FVL transgenic mice (C57BL/6 background) by immunization with β2-glycoprotein I (β2-GPI). Autoantibody levels were measured at 1 and 5 months post-immunization. Mice were tested at 4 months post-immunization for behavior and cognitive function in the staircase, elevated plus-maze, and swim T-maze tests. Brains were removed and analyzed by immunohistochemistry for inflammatory markers and neurodegenerative processes. Results A single immunization with β2-GPI induced significantly higher and longer-lasting immune responses, and this was dependent on the number of FVL alleles. At 1 and 5 months post-immunization, levels of antibodies rose from 1.17 ± 0.07 to 1.62 ± 0.17 (optical density units; ODU) in homozygous FVL mice, compared with stable levels of 0.59 ± 0.17 and 0.48 ± 0.16 ODU in heterozygous FVL mice and a drop from 1.62 ± 0.21 to 0.61 ± 0.13 ODU in wild-type mice. Behavioral and cognitive clinical features of eAPS were also correlated with FVL allele load, as assessed by the elevated plus-maze (altered anxiety), staircase (hyperactivity and higher exploration), and swim T-maze (impaired learning) tests. Histological studies identified significant neurodegenerative changes in both grey and white matter in the eAPS-FVL brains. In spite of the potential interaction of two prothrombotic disease states, there were no ischemic lesions seen in this group. Conclusions The results indicate that genetically mediated coagulopathies increase the risk of developing coagulation-targeted autoimmune responses, and suggest the importance of antibody-mediated neurodegenerative processes in the brain in APS.

Full Text Available Severe eosinophilic syndromes related to the administration or use of unsuspected immunogenic substances have been described previously. Many of these diseases presented initially as clusters or isolated cases. The spanish toxic oil syndrome, the eosinophilia myalgia syndrome, and nephrogenic systemic fibrosis are examples of such diseases. We describe 2 cases of a severe eosinophilic syndrome characterized by marked peripheral blood eosinophilia (>15,000 cells/ml, mononeuritis multiplex, and necrotizing vasculitis which developed in a close temporal association with the recent onset use of nonprescription probiotics. There was no history of a prior autoimmune disease. Although both cases had prompt response to immunosuppression with rapid resolution of peripheral blood eosinophilia and accompanying constitutional symptoms, they remained with permanent neurological deficits.

Full Text Available Evans syndrome (ES is an autoimmune disorder characterized by simultaneous or sequential development of autoimmune hemolytic anemia, immune thrombocytopenia, and/or neutropenia. ES can be classified as a primary (idiopathic or secondary (associated with an underlying disease syndrome. We report a case of ES in an elderly patient in the presence of multiple trigger factors such as recent influenza vaccine, marginal zone lymphoma, and neuroendocrine tumor G1. Whether this association is casual or causal remains a matter of speculation. It is however necessary to have a thorough work-up in a newly diagnosed ES and a more accurate search of miscellaneous factors especially in elderly patients.

Objectives Reports of an association between antineutrophil cytoplasmic antibodies (ANCA) and autoimmune neutropenia have rarely included cases of proven vasculitis. A case of ANCA-associated vasculitis (AAV) with recurrent neutropenia is described and relevant literature on the association between ANCA, neutropenia, and vasculitis is reviewed. Methods Longitudinal clinical assessments and laboratory findings are described in a patient with AAV and recurrent episodes of profound neutropenia from December 2008 – October 2010. A PubMed database search of the medical literature was performed for papers published from 1960 through October 2010 to identify all reported cases of ANCA and neutropenia. Results A 49 year-old man developed recurrent neutropenia, periodic fevers, arthritis, biopsy-proven cutaneous vasculitis, sensorineural hearing loss, epididymitis, and positive tests for ANCA with specificity for antibodies to both proteinase 3 and myeloperoxidase. Antineutrophil membrane antibodies were detected during an acute neutropenic phase and were not detectable in a post-recovery sample, whereas ANCA titers did not seem to correlate with neutropenia. An association between ANCA and neutropenia has been reported in 74 cases from 24 studies in the context of drug/toxin exposure, underlying autoimmune disease, or chronic neutropenia without underlying autoimmune disease. In these cases, the presence of atypical ANCA patterns and other antibodies were common; however, vasculitis was uncommon and when it occurred was usually limited to the skin and in cases of underlying toxin exposure. Conclusions ANCA is associated with autoimmune neutropenia, but systemic vasculitis rarely occurs in association with ANCA and neutropenia. The interaction between neutrophils and ANCA may provide insight into understanding both autoimmune neutropenia and AAV. PMID:21507463

Autoimmune Addison's disease (AAD) is a rare but highly heritable condition. The BACH2 protein plays a crucial role in T lymphocyte maturation, and allelic variation in its gene has been associated with a number of autoimmune conditions. We aimed to determine whether alleles of the rs3757247 single nucleotide polymorphism (SNP) in the BACH2 gene are associated with AAD. This case-control association study was performed in two phases using Taqman chemistry. In the first phase, the rs3757247 SNP was genotyped in 358 UK AAD subjects and 166 local control subjects. Genotype data were also available from 5154 healthy UK controls from the Wellcome Trust (WTCCC2) for comparison. In the second phase, the SNP was genotyped in a validation cohort comprising 317 Norwegian AAD subjects and 365 controls. The frequency of the minor T allele was significantly higher in subjects with AAD from the United Kingdom compared to both the local and WTCCC2 control cohorts (58% vs 45 and 48%, respectively) (local controls, P = 1.1 × 10 -4 ; odds ratio [OR], 1.68; 95% confidence interval [CI], 1.29-2.18; WTCCC2 controls, P = 1.4 × 10 -6 ; OR, 1.44; 95% CI, 1.23-1.69). This finding was replicated in the Norwegian validation cohort (P = .0015; OR, 1.41; 95% CI, 1.14-1.75). Subgroup analysis showed that this association is present in subjects with both isolated AAD (OR, 1.53; 95% CI, 1.22-1.92) and autoimmune polyglandular syndrome type 2 (OR, 1.37; 95% CI, 1.12-1.69) in the UK cohort, and with autoimmune polyglandular syndrome type 2 in the Norwegian cohort (OR, 1.58; 95% CI, 1.22-2.06). We have demonstrated, for the first time, that allelic variability at the BACH2 locus is associated with susceptibility to AAD. Given its association with multiple autoimmune conditions, BACH2 can be considered a "universal" autoimmune susceptibility locus.

2014-11-01

Full Text Available Purpose: We report a case of laryngeal edema associated with the Vogt-Koyanagi-Harada (VKH syndrome. Patient and Methods: A 32-year-old African-American female presented with a 12-day prodrome, including headache, tinnitus and shortness of breath, which preceded sudden photophobia and bilateral visual loss. Examination and clinical testing were most consistent with VKH, and the patient improved with intravenous methylprednisolone therapy. Results: The patient had persistent dyspnea, which was out of proportion to chest CT findings and which was exacerbated during a recurrence of VKH. Flexible fiberoptic laryngoscopy with stroboscopy revealed diffuse laryngeal edema. Symptoms were alleviated with breathing exercises. Conclusions: Several autoimmune diseases may cause diffuse laryngeal edema. In this case, VKH was associated with the patient's glottic edema and dyspnea. We recommend that laryngeal edema be considered in the differential diagnosis for patients with dyspnea and VKH.

2010-11-01

Full Text Available Abstract Introduction We report the case of an unusual association of Coffin-Siris syndrome with Mayer-Rokitansky-Küster-Hauser syndrome. This association has never previously been reported in the medical literature. Case presentation A nine-year-old Indian girl was referred to our hospital for growth retardation, mental retardation, lax joints, generalized hypertrichosis, and hypoplastic fifth fingernails and toenails. A thorough medical examination and evaluation revealed she had phenotypic features of Coffin-Siris syndrome, with Mayer-Rokitansky-Küster-Hauser syndrome on radiological evaluation. The karyotype of our patient was normal. Conclusion In an unexplained case of mental retardation with facies suggestive of Coffin-Siris syndrome, association with Mayer-Rokitansky-Küster-Hauser syndrome should be considered and the patient should be evaluated for the same. Both of these syndromes may have a common pathogenesis, as yet unknown. This case report has broad implications, as similar cases in future may give insights into the pathogenesis of both these syndromes.

Williams syndrome is a rare genetic disorder, that occurs equally in all ethnic groups and both sexes. The diagnosis might be missed during childhood in mild cases. However, establishing the diagnosis is important, not only to find the cause of intellectual disability but to look for cardiovascular, endocrine, psychiatry, urology and other conditions, which can occur at any age in the patients' lifetime. This case report presents the story of 47-year-old woman, who was admitted with haematemesis. During her stay on the ward, in the light of the distinctive facial features, mental retardation, and social behaviour patterns, the possibility of Williams syndrome emerged. Later, the diagnosis was confirmed by genetic analysis. This female is the oldest living patient with Williams syndrome in Hungary. Orv Hetil. 2017; 158(47): 1883-1888.

Full Text Available Waardenburg Syndrome is a rare disorder of neural crest cell development. It is genetically inherited. Varying in prevalence from 1:42000 to 1:50,000, it compromises approximately 2-5% of congenital deaf children. The syndrome is not expressed in its complete form, in about 20% cases, which adds for its heterogenisity . Even among people affected in the same family,the features do vary. Unilateral heterochromia that manifests as lighter pigmentation of one iris is associated with Waardenburg syndrome and Parry-Romberg syndrome and less commonly with Hirschsprung disease. A case of ten yrs. old boy with a typical facial profile and hearing loss is reported.

2012-01-01

Full Text Available Introduction: Polycystic ovary syndrome (PCOS is a common endocrinopathy of women of child-bearing age. Although some studies have suggested an association between PCOS and autoimmune thyroiditis, to our knowledge, only a few cases indicating association between PCOS and Graves′ disease are reported. Objective: We aim to describe this first case series of six women presenting with PCOS and Graves′ disease together. Materials and Methods: Women attending the endocrinology clinic at a tertiary care centre in north India and fulfilling the AE-PCOS criteria for diagnosis of PCOS were studied using a predefined proforma for any clinical, biochemical and imaging features of Graves′ disease. Results: The series consisted of six women with a mean age of 27.5 years and menarche as 12.6 years. All women were lean with mean BMI of 22.73 kg / m 2 and three out of six had waist circumference <80 cm. The mean FG score of subjects was 16.66 and average total testosterone was 77.02 ng / dl (25.0-119.64. All the patients had suppressed TSH, the average being 0.052 μIU/ml (0.01-0.15. Thyroid gland was enlarged in all clinically and on ultrasonography and imaging with 99m Tc and/or RAIU revealed diffuse increased uptake. Conclusions: The association of a rare disorder like Graves′ disease with a relatively common disorder like PCOS is unlikely to be because of a chance alone and may point to a common aetiopathogenic linkage leaving a scope for molecular characterization.

Successful treatment of pediatric IgG4 related systemic disease with mycophenolate mofetil: case report and a review of the pediatric autoimmune pancreatitis literature

Directory of Open Access Journals (Sweden)

Cron Randy Q

2011-01-01

Full Text Available Abstract Autoimmune pancreatitis is frequently associated with elevated serum and tissue IgG4 levels in the adult population, but there are few reports of pediatric autoimmune pancreatitis, and even fewer reports of IgG4 related systemic disease in a pediatric population. The standard of care treatment in adults is systemic corticosteroids with resolution of symptoms in most cases; however, multiple courses of corticosteroids are occasionally required and some patients require long term corticosteroids. In these instances, steroid sparing disease modify treatments are in demand. We describe a 13-year-old girl with IgG4 related systemic disease who presented with chronic recurrent autoimmune pancreatitis resulting in surgical intervention for obstructive hyperbilirubinemia and chronic corticosteroid treatment. In addition, she developed fibrosing medianstinitis as part of her IgG4 related systemic disease. She was eventually successfully treated with mycophenolate mofetil allowing for discontinuation of corticosteroids. This is the first reported use of mycophenolate mofetil for IgG4 related pancreatitis. Although autoimmune pancreatitis as part of IgG4 related systemic disease is rarely reported in pediatrics, autoimmune pancreatitis is also characterized as idiopathic fibrosing pancreatitis. All pediatric autoimmune pancreatitis cases reported in the world medical literature were identified via a PUBMED search and are reviewed herein. Twelve reports of pediatric autoimmune pancreatitis were identified, most of which were treated with corticosteroids or surgical approaches. Most case reports failed to report IgG4 levels, so it remains unclear how commonly IgG4 related autoimmune pancreatitis occurs during childhood. Increased evaluation of IgG4 levels in patients with autoimmune pancreatitis may shed further light on the association of IgG4 with pancreatitis and the underlying pathophysiology.

Full Text Available Graves' disease is a common condition and is known to have a wide range of effects on a variety of organs. Hepatic dysfunction ranging from mild to severe due to direct effect of high circulating thyroid hormones as well as a deleterious effect of antithyroid medications (methimazole and propylthiouracil has been well - documented in literature. However, severe autoimmune hepatitis (AIH associated with Graves' disease is rare and limited to few case reports only. A 38-year-old woman presented with abdominal pain and yellowish discolouration of conjunctivae. On investigation, she was found to have Graves' disease and AIH. The liver histopathology showed typical features of AIH. She responded excellently to glucocorticoid therapy with normalisation of thyroid function and liver histology. The case is discussed with relevant literature review.

Coeliac disease (CD) is an autoimmune disorder of the small bowel associated with increased risk of additional autoimmune diseases (ADs).To investigate the prevalence of ADs in a population of adult coeliac patients.This was a retrospective case-control study. Data from coeliac patients and controls referred to a tertiary center between 2013 and 2016 were collected. The frequency of ADs and the unadjusted and adjusted odds ratios (ORs) for age, gender, disease duration, and body mass index with their 95% confidence intervals (CIs) were evaluated.Two hundred fifty-five patients with CD (median age 37.1 years; 206 women) were matched with 250 controls. ADs were more frequent (35.3%) in coeliac patients than in controls (15.2%). Adjusted ORs for the presence of only 1, at least 1, and more than 1 AD were 3.13 (95% CI 1.81-5.42, P disease.

Los, Evan; Baines, Hayley; Guttmann-Bauman, Ines

2017-01-01

Most cases of Van der Woude syndrome are caused by a mutation to interferon regulatory factor 6 on chromosome 1. Turner syndrome is caused by complete or partial absence of the second sex chromosome in girls. We describe a unique case of the two syndromes occurring concurrently though apparently independently in a girl with Van der Woude syndrome diagnosed at birth and Turner syndrome at 14 years 9 months. Short stature was initially misattributed to Van der Woude syndrome and pituitary insufficiency associated with clefts before correctly diagnosing Turner syndrome. We discuss the prevalence of delayed diagnosis of Turner syndrome, the rarity of reports of concurrent autosomal chromosome mutation and sex chromosome deletion, as well as the need to consider the diagnosis of Turner syndrome in all girls with short stature regardless of prior medical history.

Full Text Available Introduction. Harlequin syndrome is a very rare neurological condition characterized by redness and excessive sweating of one half of the face in response to exercise and emotions. In most cases this disorder is not life-threatening. Objective. To present diagnostic difficulties of Harlequin syndrome in dermatological practice. Case report. We present a case of a 30-year-old man with redness and excessive sweating of the right half of the face as a result of exercise that was observed during the diagnosis of chronic urticaria at the Department of Dermatology. The patient was examined ophthalmologically and neurologically, had a CT scan of the head, and the Minor test performed. Idiopathic Harlequin syndrome was diagnosed based on case history and workup results. Conclusions . Harlequin syndrome occurs most often in the form of an idiopathic condition, but neurologic and ophthalmologic assessment should be performed since some diseases, such as brainstem infarction and schwannoma of the upper chest, may initially appear as Harlequin syndrome.

Valeria Muller

2016-01-01

Full Text Available We report three cases of effective management of infertility in women with a history of repeated unsuccessful IVF attempts, who have developed antibodies to hCG. A novel approach to conservative treatment of immunologic reproductive failure, suggested for selected patients, included membrane plasmapheresis, combined prednisolone, and intravenous immunoglobulin therapy. No adverse side effects were observed; all cases resulted in pregnancy and subsequent life births. In order to be given an adequate efficient treatment, women with recurrent implantation failure should be suspected for autoimmune factor of infertility and its possible association with anti-hCG autoimmunity.

Autoimmune gastritis: Pathologist’s viewpoint

Coati, Irene; Fassan, Matteo; Farinati, Fabio; Graham, David Y; Genta, Robert M; Rugge, Massimo

2015-01-01

Western countries are seeing a constant decline in the incidence of Helicobacter pylori-associated gastritis, coupled with a rising epidemiological and clinical impact of autoimmune gastritis. This latter gastropathy is due to autoimmune aggression targeting parietal cells through a complex interaction of auto-antibodies against the parietal cell proton pump and intrinsic factor, and sensitized T cells. Given the specific target of this aggression, autoimmune gastritis is typically restricted to the gastric corpus-fundus mucosa. In advanced cases, the oxyntic epithelia are replaced by atrophic (and metaplastic) mucosa, creating the phenotypic background in which both gastric neuroendocrine tumors and (intestinal-type) adenocarcinomas may develop. Despite improvements in our understanding of the phenotypic changes or cascades occurring in this autoimmune setting, no reliable biomarkers are available for identifying patients at higher risk of developing a gastric neoplasm. The standardization of autoimmune gastritis histology reports and classifications in diagnostic practice is a prerequisite for implementing definitive secondary prevention strategies based on multidisciplinary diagnostic approaches integrating endoscopy, serology, histology and molecular profiling.

2010-11-08

We report the case of an unusual association of Coffin-Siris syndrome with Mayer-Rokitansky-Küster-Hauser syndrome. This association has never previously been reported in the medical literature. A nine-year-old Indian girl was referred to our hospital for growth retardation, mental retardation, lax joints, generalized hypertrichosis, and hypoplastic fifth fingernails and toenails. A thorough medical examination and evaluation revealed she had phenotypic features of Coffin-Siris syndrome, with Mayer-Rokitansky-Küster-Hauser syndrome on radiological evaluation. The karyotype of our patient was normal. In an unexplained case of mental retardation with facies suggestive of Coffin-Siris syndrome, association with Mayer-Rokitansky-Küster-Hauser syndrome should be considered and the patient should be evaluated for the same. Both of these syndromes may have a common pathogenesis, as yet unknown. This case report has broad implications, as similar cases in future may give insights into the pathogenesis of both these syndromes.

A Case Report of Nonvasculitic Autoimmune Inflammatory Meningoencephalitis with Sensory Ganglionopathy: A Rare Presentation of Sjögren Syndrome

João Peres

2017-01-01

Full Text Available A 68-year-old Caucasian female was admitted to the emergency department with a progressive history of behavioural symptoms and anxiety followed by visual and auditory hallucinations, forgetfulness, and impaired gait in the previous 3 months. On examination she was psychotic and had a postural and rest tremor of the upper limbs, cogwheel rigidity of the four limbs, retropulsion on standing position, and inability to walk. During the following 2 weeks she developed xerostomia and unilateral parotiditis that improved with steroids. A simultaneous improvement of the cognitive abilities allowed for the detection of sensory ataxia of the lower limbs. Sensory ganglionopathy was then detected with electrophysiological studies. A diagnosis of Sjögren syndrome was suspected and confirmed by salivary gland scintigraphy, Schirmer’s test, and submaxillary gland biopsy. We report a case of Sjögren syndrome associated with central and peripheral nervous system involvement, without sicca symptoms preceding the neurological clinical picture. The coexistence of ganglionopathy and a favourable response to immunosuppression are key features that can lead to the correct diagnosis in cases with atypical CNS symptoms, mimicking a rapidly progressive dementia.

Elderly patients with autoimmune gastritis might have different symptoms than those of young patients. The aim of the present study was to compare presented symptoms and laboratory parameters associated with autoimmune gastritis in both old and young age groups. A total of 355 patients with autoimmune gastritis were stratified into two groups: 65 years or older (n = 119, mean age 69.47 ± 5.027 years), and under 65 years (n = 236, mean age 45.79 ± 10.51 years). These two groups were then evaluated and compared by means of clinical symptoms, concurrent autoimmune diseases, serum gastrin, vitamin B 12 and chromogranin A levels, and the presence of enterochromograffin-like cell hyperplasia. Among 119 older patients, 35 had dyspeptic symptoms, and 84 patients were referred for vitamin B 12 and/or iron deficiency. In the younger group (n = 236), there were more patients who had dyspeptic symptoms (36 vs 200, P gastritis that are older and younger than 65 years-of-age. Elderly patients with autoimmune gastritis were investigated more commonly for vitamin B 12 and/or iron deficiency. Polyautoimmunity and multiple autoimmune syndrome were more common, and serum gastrin and chromogranin A levels were significantly higher in older patients.

In this study, serological screening for celiac disease (CD) was performed in patients with autoimmune cholestasis to define the prevalence of such an association and to evaluate the impact of gluten withdrawal on liver disease associated with gluten sensitive enteropathy. Immunoglobulin A endomysial, human and guinea pig tissue transglutaminase antibodies, and immunoglobulin A and G gliadin antibodies were sought in 255 patients with primary biliary cirrhosis, autoimmune cholangitis, and primary sclerosing cholangitis. Immunoglobulin A endomysial and human tissue transglutaminase antibodies were positive in nine patients (seven primary biliary cirrhosis, one autoimmune cholangitis, and one primary sclerosing cholangitis), whose duodenal biopsy results showed villous atrophy consistent with CD. Two of these patients had a malabsorption syndrome, and one had iron-deficiency anemia. Clinical and biochemical signs of cholestasis did not improve after gluten withdrawal in the three patients with severe liver disease. A longer follow-up of the six celiac patients with mild liver damage is needed to clarify whether gluten restriction can contribute to slow down the progression of liver disease. The high prevalence of CD (3.5%) in autoimmune cholestasis suggests that serological screening for CD should be routinely performed in such patients by immunoglobulin A endomysial or human tissue transglutaminase antibodies.

Role of inflammasomes in inflammatory autoimmune rheumatic diseases.

Science.gov (United States)

Yi, Young-Su

2018-01-01

Inflammasomes are intracellular multiprotein complexes that coordinate anti-pathogenic host defense during inflammatory responses in myeloid cells, especially macrophages. Inflammasome activation leads to activation of caspase-1, resulting in the induction of pyroptosis and the secretion of pro-inflammatory cytokines including interleukin (IL)-1β and IL-18. Although the inflammatory response is an innate host defense mechanism, chronic inflammation is the main cause of rheumatic diseases, such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), ankylosing spondylitis (AS), and Sjögren's syndrome (SS). Since rheumatic diseases are inflammatory/autoimmune disorders, it is reasonable to hypothesize that inflammasomes activated during the inflammatory response play a pivotal role in development and progression of these diseases. Indeed, previous studies have provided important observations that inflammasomes are actively involved in the pathogenesis of inflammatory/autoimmune rheumatic diseases. In this review, we summarize the current knowledge on several types of inflammasomes during macrophage-mediated inflammatory responses and discuss recent research regarding the role of inflammasomes in the pathogenesis of inflammatory/autoimmune rheumatic diseases. This avenue of research could provide new insights for the development of promising therapeutics to treat inflammatory/autoimmune rheumatic diseases.

Full Text Available Evans syndrome (ES is a rare autoimmune disorder whose exact pathophysiology is unknown. It is characterized by the simultaneous or subsequent development of autoimmune hemolytic anemia (AIHA and immune thrombocytopenia (ITP. Intravascular hemolysis, with hemoglobinemia, is known to produce acute kidney injury; however, the development of intratubular hemoglobin casts (hemoglobin cast nephropathy in the setting of acute hemolysis is uncommon. Likewise, the association of ES and acute renal failure is equally uncommon. We present a case of a 7-year-old girl with ES who developed acute kidney injury in the setting of intravascular hemolysis and had widespread intratubular hemoglobin casts.

2014-06-01

Full Text Available Low vitamin D levels have been described in obese individuals and in some autoimmune diseases, such as Systemic Lupus Erythematosus (SLE and primary antiphospholipid syndrome (pAPS. In particular, more than 50% of premenopausal women with pAPS have hypovitaminosis D. In this issue we report a case of an obese, premenopausal, and hypertensive woman with pseudo-Cushing syndrome, affected by deep venous thrombosis associated with pulmonary embolism after rib fracture who presented hypovitaminosis D. 7 years before, diagnosis of pAPS had been made after the detection of thrombocytopenia (present at a young age and arterial ischemia of a lower limb. For seven years she was treated with acetylsalicylic acid without complications. We found positive anti-dsDNA antibodies, a triple antiphospholipid antibodies (aPL positivity and levels of vitamin D < 4 µg/l. The case report arises some questions: is vitamin D deficiency due to obesity or APS? Is the positivity of anti-dsDNA indicative of progression to SLE? Is preventive therapy with hydroxychloroquine indicated? Does the high-risk aPL profile justify a high-intensity and life-long anticoagulation regimen?http://dx.doi.org/10.7175/cmi.v8i2.912

Advances in genomics have allowed unbiased genetic studies of human disease with unexpected insights into the molecular mechanisms of cellular immunity and autoimmunity1. We performed whole exome sequencing (WES) and targeted sequencing in patients with an apparent Mendelian syndrome of autoimmune disease characterized by high-titer autoantibodies, inflammatory arthritis and interstitial lung disease (ILD). In five families, we identified four unique deleterious variants in the Coatomer subunit alpha (COPA) gene all located within the same functional domain. We hypothesized that mutant COPA leads to a defect in intracellular transport mediated by coat protein complex I (COPI)2–4. We show that COPA variants impair binding of proteins targeted for retrograde Golgi to ER transport and demonstrate that expression of mutant COPA leads to ER stress and the upregulation of Th17 priming cytokines. Consistent with this pattern of cytokine expression, patients demonstrated a significant skewing of CD4+ T cells toward a T helper 17 (Th17) phenotype, an effector T cell population implicated in autoimmunity5,6. Our findings uncover an unexpected molecular link between a vesicular transport protein and a syndrome of autoimmunity manifested by lung and joint disease. These findings provide a unique opportunity to understand how alterations in cellular homeostasis caused by a defect in the intracellular trafficking pathway leads to the generation of human autoimmune disease.

Sweet syndrome (acute, febrile, neutrophilic dermatosis) is characterized by the acute onset of an eruption of painful nodules or erythematous or violaceous plaques on the limbs, face and neck. These symptoms are accompanied by fever. The diagnostic features include histopathological findings of dermal neutrophilic infiltration without leukocytoclastic vasculitis or peripheral blood leukocytosis. Sweet syndrome is associated with infection, malignancies, autoimmune disease, pregnancy, and drugs. Patients with Sweet syndrome demonstrate a complete and rapid response to systemic steroid administration. Recently, a distinct variant of Sweet syndrome was reported, termed "histiocytoid Sweet syndrome", in which the infiltration of myeloperoxidase-positive histiocytoid mononuclear cells are observed (in contrast to the infiltration of neutrophils). The other clinical features are similar to those of classic Sweet syndrome. Pediatric Sweet syndrome is uncommon, and the histiocytoid type is even rarer. To date, four cases of histiocytoid Sweet syndrome have been reported in children. Herein, we describe a case of histiocytoid Sweet syndrome in an otherwise healthy 10-year-old boy with no underlying systemic disease in whom non-steroidal, anti-inflammatory drug treatment was successful.

The Gorlin-Goltz syndrome (GGS) (the nevoid basal cell carcinoma syndrome-NBCCS) is an autosomal dominant syndrome caused by mutations found on chromosome 9. The syndrome is characterized by increased predisposition to develop a basal cell carcinoma and associated with multiorgan anomalies. To present a case of GGS and explain modern standards of care for patients with this syndrome. Authors report the case of a 36-year-old patient who was admitted to the Plastic Surgery Clinic due to numerous basal cell carcinomas. Previously patient underwent an orthopaedic, neurologic, dermatologic, stomatologic and surgery treatment due to particular anomalies which characterize this syndrome. Comprehensive interview and broadening of the diagnostics enabled to diagnose GGS and to introduce the appropriate treatment. GGS is a multidisciplinary problem and widespread knowledge of this syndrome could accelerate the diagnosis process. Early diagnosis of GGS allows to introduce the secondary prophylaxis and to apply the appropriate treatment to slow the progress of the syndrome.

2010-01-01

Full Text Available Adipose tissue produces a wide range of proteins that may influence the immune system. In this study, we assessed the serum levels of leptin, adiponectin, and ghrelin, in association with the measurements of body composition, in 15 female patients with various autoimmune diseases (systemic lupus erythematosus, primary Sjögren's syndrome, sarcoidosis, mixed connective tissue disease, vasculitis, CREST syndrome, and polymyositis and in 15 healthy female controls. There were no statistically significant differences between the patients and controls with regard to serum leptin, serum ghrelin, global fat mass, adiposity, and fat mass in the android or gynoid regions, whereas serum adiponectin levels were higher in patients than controls (16.3±1.6 μg/mL versus 9.7±0.6 μg/mL; =.01. As adiponectin is known to exhibit potent anti-inflammatory properties, a high adiponectinemia in patients with systemic autoimmune disease may mitigate the inflammatory response. However, the precise consequences of these elevated serum adiponectin levels on the metabolic syndrome development and atherosclerotic cardiovascular risk in this patient population still needs to be determined.

A Case of Morvan Syndrome Mimicking Amyotrophic Lateral Sclerosis With Frontotemporal Dementia.

2016-06-01

Morvan syndrome is a rare autoimmune/paraneoplastic disorder involving antibodies to the voltage-gated potassium channel complex. It is defined by subacute encephalopathy, neuromuscular hyperexcitability, dysautonomia, and sleep disturbance. It may present a diagnostic dilemma when trying to differentiate from amyotrophic lateral sclerosis with frontotemporal dementia. A 76-year-old man with a history of untreated prostate adenocarcinoma was evaluated for subacute cognitive decline, diffuse muscle cramps, and hyponatremia. MRI demonstrated atrophy most prominent in the frontal and temporal regions. Electromyography (EMG) demonstrated diffuse myokymia/neuromyotonia. Polysomnography lacked REM and N3 sleep. Paraneoplastic panel detected antibodies to voltage-gated potassium channel complex (CASPR2 subtype). It is difficult to differentiate between Morvan syndrome and amyotrophic lateral sclerosis with frontotemporal dementia with examination and neuroimaging alone. There may be a link between Morvan syndrome and prostate adenocarcinoma which could help with screening/diagnosis. The authors found that laboratory and neurophysiological tests are indispensable in diagnosing and treating Morvan syndrome.

Towards a further understanding of prenatal thyroid theory of homosexuality: Autoimmune thyroiditis, polycystic ovary syndrome, autism and low birth weight

Directory of Open Access Journals (Sweden)

2017-10-01

Full Text Available Research into the neurobiological origins of same-sex attraction is inconclusive. A recent theory of homosexuality posited that maternal thyroid dysfunction during pregnancy is associated with an increased rate of homosexual orientation in offspring. Relevant studies from the prenatal thyroid model perspective were reviewed, the major findings of which are as follows: i An increased prevalence of Hashimoto’s disease in lesbian women suggests a maternal and even familial presence of the same autoimmune thyroid disease. Female-tomale transsexuals and lesbian women were also reported to have higher rates of polycystic ovary syndrome (PCOS. Over the last several years, reports suggesting a strong link between PCOS and thyroid autoimmunity have accumulated. ii The increased risk of autism spectrum disorders (ASD in the offspring of mothers with thyroid autoimmunity in pregnancy and the association between ASD and gender dysphoria indicate a link between maternal thyroid dysfunction and gender dysphoria/same-sex attraction in the offspring. iii The high risk of miscarriage and retarded fetal growth in pregnancies of mothers who give birth to homosexual offspring can be explained by the impact of maternal thyroid dysfunction during pregnancy. This perspective review highlights relevant research findings and integrates them into the prenatal thyroid model of homosexuality. A better understanding of the mechanisms involved in the generation of same-sex orientation will contribute to the betterment of individual lives, as well as of society.

Nuclear Factor-kappaB in Autoimmunity: Man and Mouse.

Science.gov (United States)

Miraghazadeh, Bahar; Cook, Matthew C

2018-01-01

NF-κB (nuclear factor-kappa B) is a transcription complex crucial for host defense mediated by innate and adaptive immunity, where canonical NF-κB signaling, mediated by nuclear translocation of RelA, c-Rel, and p50, is important for immune cell activation, differentiation, and survival. Non-canonical signaling mediated by nuclear translocation of p52 and RelB contributes to lymphocyte maturation and survival and is also crucial for lymphoid organogenesis. We outline NF-κB signaling and regulation, then summarize important molecular contributions of NF-κB to mechanisms of self-tolerance. We relate these mechanisms to autoimmune phenotypes described in what is now a substantial catalog of immune defects conferred by mutations in NF-κB pathways in mouse models. Finally, we describe Mendelian autoimmune syndromes arising from human NF-κB mutations, and speculate on implications for understanding sporadic autoimmune disease.

Melkersson-Rosenthal syndrome is characterised by a triad of recurrent orofacial swelling, relapsing facial paralysis, and fissured tongue. The classic triad is infrequent and oligosymptomatic variants are seen more frequently. CTS is a rare complication of facial nerve paralysis characterised by inappropriate lacrimation on the side of the palsy in response to salivary stimuli. It results from aberrant reinnervation of the lacrimal gland by salivary parasympathetic fibres. The therapeutic approach for an acute bout of Melkersson-Rosenthal syndrome consists mainly of steroid administration. CTS management is composed of anticholinergic drugs and surgical procedures. Botulin toxin injection into the lacrimal gland is the most modern therapeutic option. In the case presented CTS developed in a 50-year-old man after 5 incidents of facial palsy due to Melkersson-Rosenthal syndrome. The case deserves attention due to the rarity of the observed symptoms and signs.

Full Text Available Cogan’s syndrome (CS is a rare autoimmune disorder characterized by audiovestibular dysfunction and ocular inflammation. Currently, there is no specific serum autoantibody used in the diagnostic workup of CS. Treatment is based on immunosuppressive agents, mainly corticosteroids as first-line choice. Recently, novel therapeutic modalities in CS have emerged. These include tumor necrosis factor-α inhibitors and other biologicals. Despite medical treatment, hearing loss may progress to irreversible bilateral profound SNHL in approximately half of CS patients resulting in candidacy for cochlear implantation (CI. Due to the inflammatory nature of the disease that is causing endosteal reaction with partial obliteration or complete neoossification of the intracochlear ducts, early CI is recommended. CI provides excellent and stable hearing rehabilitation with high score of word and sentence recognition. In this review, we will discuss different aspects of CS including clinical presentation, diagnosis, treatment, and future directives.

Autoimmune liver diseases (ALDs) are known to be associated with systemic autoimmune rheumatic diseases (SARDs) and their autoantibodies. We aimed to study the prevalence of SARDs and related autoantibodies, as well as their prognostic implications in a group of patients with ALDs. This was a cross-sectional study. Sixty patients with ALDs (38.3% with autoimmune hepatitis; 11.7% with primary biliary cirrhosis; 25% with primary sclerosing cholangitis and 25% with overlap syndrome) were studied for the presence of SARDs and their autoantibodies. There was autoimmune rheumatic disease in 20% of the studied sample. Systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) were the commonest (11.6% and 5%, respectively). Antinuclear antibodies (ANAs) were present in 35% of the patients, followed by anti-Ro (20.0%); anti-nucleosome (18.3%); rheumatoid factor (10%) anti-CCP (8.3%); anti-RNP (8.3%); anti-ds-DNA (6.6%); anti-La (3.3%); anti-Sm (3.3%), anti-ribosomal P (3.3%). Anti-Ro (p = 0.0004), anti-La (p = 0.03), anti-RNP (p = 0.04) and anti-Sm (p = 0.03) were commonly found in patients with SARD, but not anti-DNA, anti-nucleosome and anti-ribosomal P. No differences were found in liver function tests regarding to the presence of autoantibodies. There was a high prevalence of SARD and their autoantibodies in ALD patients. Anti-Ro, anti-La, anti-RNP and anti-Sm positivity points to an association with systemic autoimmune rheumatic diseases. The presence of autoantibodies was not related to liver function tests.

Clinical significance of autoantibodies in autoimmune hepatitis.

The accurate diagnosis and classification of autoimmune hepatitis (AIH) rely upon the detection of characteristic autoantibodies. Positivity for anti-nuclear (ANA) and/or anti-smooth muscle (SMA) autoantibodies defines AIH type 1 (AIH-1), whereas anti-liver kidney microsomal type 1 (anti-LKM1) and/or anti-liver cytosol type 1 (anti-LC1) define AIH type 2 (AIH-2). ANA and SMA, and less commonly anti-LKM1, have also been detected in de-novo autoimmune hepatitis developing after liver transplantation, a condition that may affect patients transplanted for non-autoimmune liver disease. The diagnostic autoantibodies associated with AIH-1 are also detected in the paediatric AIH/sclerosing cholangitis overlap syndrome, referred to as autoimmune sclerosing cholangitis (ASC). ASC, like adult primary sclerosing cholangitis, is often associated with atypical perinuclear anti-neutrophil cytoplasmic autoantibodies (p-ANCA), although p-ANCA are also detected in other autoimmune liver diseases. These associations highlight the necessity for simple and prompt diagnostic autoantibody testing, and the requirement for the accurate interpretation of the results of the tests in the clinical context. Fine-mapping of antigenic autoantibody targets has facilitated the development of rapid molecular assays that have the potential to revolutionise the field if properly standardised and when used in combination with classical immunofluorescence. Despite their diagnostic significance, the pathogenic role of the various autoantibodies and the mechanisms by which they can potentially inflict damage onto the liver cell remain a topic for further research.

To evaluate the efficacy of topical tacrloimus eye drops in the treatment of keratitis associated with autoimmune polyglandular syndrome (APS)-1. This is a retrospective review of 10 patients with APS-1. The patients were treated with topical tacrolimus 0.01% solution at The Eye Center, between 1 March 2012 and 30 April 2016. The outcome measures included improvement in visual acuity, photophobia and keratitis following treatment. Clinical assessment was carried out before, during and on the last visit following initiation of therapy. A total of 10 patients were included. There were five male and five female patients. The mean age was 11 years with age range of 3-42 years. The mean duration of treatment with topical tacrolimus was 26 months (range 8-46 months). There was improvement of photophobia in 7 out of 10 patients following therapy with topical tacrolimus. In three patients, the photophobia was persistent. There was no clinically detectable improvement in the severity of keratitis in all patients. The mean best corrected visual acuity was 0.1 before and following therapy. Topical tacrolimus is effective in reducing the photophobia in patients with APS-1-associated keratitis, but showed no effects on the severity of keratitis.

Full Text Available Background. Autoimmune encephalitis is a disorder characterised by the subacute onset of seizures, short-term memory loss, and psychiatric and behavioural symptoms. Initially, it was recognised as a paraneoplastic disorder, but recently a subgroup of patients without systemic cancer was identified. Case Description. We describe a 20-year-old woman with Turner syndrome presenting with a treatment-resistant rapid cycling bipolar disorder with cognitive impairment. She was diagnosed with anti-AMPA-receptor encephalitis. She showed marked improvement after starting memantine and valproic acid. Conclusion. This case description emphasises the importance of timely recognition of autoimmune limbic encephalitis in patients with psychiatric manifestations and a possible predisposition to autoimmune conditions, in order to rule out malignancy and to quickly initiate treatment.

Carpal tunnel syndrome is the most frequent of tunnel syndromes in the field of the professional sphere. It is related to repetitive movements of flexion-extension of the wrist and fingers or to a support on the heel of the hands. To determine the posts in a risk and to specify the modalities of guaranteed reimbursement of professional carpal tunnel syndrome. A retrospective and descriptive study of 27 medical files of employees indemnified for professional carpal tunnel syndrome registered in the medical control services of the social security office in charge of medical insurance of Tunis and Sousse during a period of 10 years (1995-2004). There were 24 women and 3 men with the average age of 40 years all occupying posts in a risk. Their average time of service is 15 years. Tow-thirds of them work in the clothing and textile industry. The attack is bilateral in 13 cases. Nightly acroparaesthesia rules the clinical rate (44.44% of cases). Motor disorders are noted in the quarter of cases. The electromyogram had confirmed diagnosis in all of cases. The previous state study put in evidence the antecedent of carpal tunnel syndrome in 5 cases and diabetes in one case. Twenty-one patients had profit of permanent partial incapacity with a rate varying from 3 to 25%. Five had got a transfer of working place and one stayed in the same post with a half-time work. The professional origin of carpal tunnel syndrome must be called up in front of an activity in a risk. The reparation is done according to picture 82 of occupational diseases.

To summarize the recent developments in endocrine disorders associated with Down syndrome. Current research regarding bone health and Down syndrome continues to show an increased prevalence of low bone mass and highlights the importance of considering short stature when interpreting dual energy x-ray absorptiometry. The underlying cause of low bone density is an area of active research and will shape treatment and preventive measures. Risk of thyroid disease is present throughout the life course in individuals with Down syndrome. New approaches and understanding of the pathophysiology and management of subclinical hypothyroidism continue to be explored. Individuals with Down syndrome are also at risk for other autoimmune conditions, with recent research revealing the role of the increased expression of the Autoimmune Regulatory gene on 21st chromosome. Lastly, Down-syndrome-specific growth charts were recently published and provide a better assessment of growth. Recent research confirms and expands on the previously known endocrinopathies in Down syndrome and provides more insight into potential underlying mechanisms.

Full Text Available Headache associated with neurological deficits and cerebrospinal fluid lymphocytosis (HaNDL is a self-limited syndrome characterized by sudden-onset headache with a temporary neurological deficit and cerebrospinal fluid (CSF lymphocytosis. We aimed to disscus a case of HaNDL syndrome presenting during pregnancy with relevant literature. A 20-year-old female presented with a 5-day history of severe, bilateral throbbing headache accompanied by nausea, vomiting, and phonophobia. Approximately 2 days after the pain developed, she became acutely confused for less than 90 minutes. 2 days after this episode, she experienced again confusional state and left hemiparesis. There were no symptoms consistent with meningoencephalitis. She was pregnant and at 11 weeks gestation. A neurologic examination showed confusional state, bilateral papilledema, and mild left hemiparesis. The neuroradiological examination was normal. The cerebrospinal fluid revealed lymphocytic pleocytosis, mildly elevated protein, and increased opening pressure. She recovered completely after 8 days. The precise etiology of HaNDL is unknown, although an inflammatory or infectious origin and autoimmune factors have been proposed. Moreover, the risk factors and medical conditions associated with HaNDL are unknown. It is obviously difficult to determine whether the pregnancy was coincidental or associated in this case. We believe that comprehensive studies are needed to clarify the risk factors and medical conditions associated with HaNDL

Pancreatic Tuberculosis or Autoimmune Pancreatitis

Full Text Available Introduction. Isolated pancreatic and peripancreatic tuberculosis is a challenging diagnosis due to its rarity and variable presentation. Pancreatic tuberculosis can mimic pancreatic carcinoma. Similarly, autoimmune pancreatitis can appear as a focal lesion resembling pancreatic malignancy. Endoscopic ultrasound-guided fine needle aspiration provides an effective tool for differentiating between benign and malignant pancreatic lesions. The immune processes involved in immunoglobulin G4 related systemic diseases and tuberculosis appear to have some similarities. Case Report. We report a case of a 59-year-old Southeast Asian male who presented with fever, weight loss, and obstructive jaundice. CT scan revealed pancreatic mass and enlarged peripancreatic lymph nodes. Endoscopic ultrasound-guided fine needle aspiration confirmed the presence of mycobacterium tuberculosis. Patient also had high immunoglobulin G4 levels suggestive of autoimmune pancreatitis. He was started on antituberculosis medications and steroids. Clinically, he responded to treatment. Follow-up imaging showed findings suggestive of chronic pancreatitis. Discussion. Pancreatic tuberculosis and autoimmune pancreatitis can mimic pancreatic malignancy. Accurate diagnosis is imperative as unnecessary surgical intervention can be avoided. Endoscopic ultrasound-guided fine needle aspiration seems to be the diagnostic test of choice for pancreatic masses. Long-term follow-up is warranted in cases of chronic pancreatitis.

To present a case of nonparaneoplastic autoimmune retinopathy in association with myasthenia gravis in a young woman, and to report the effect of plasmapheresis as well as passage of antiretinal antibodies through the placenta. Case report. A 31-year-old woman presented with a history of myasthenia gravis and rapidly progressive vision loss at the age of 23. Funduscopic appearance and fluorescein angiographic findings on presentation were consistent with an autoimmune retinopathy. Paraneoplastic etiology was ruled out, and antiretinal antibody testing revealed positivity for autoantibodies against GAPDH, aldolase, enolase, arrestin, as well as unnamed 48-kDa and 60-kDa proteins. ARA Western Blot and immunohistochemistry profiles were unchanged by either plasmapheresis therapy or passage of serum through the maternal placenta. However, the patient's 6-month and 8-year-old daughters appeared unaffected. This is the first report of nonparaneoplastic autoimmune retinopathy associated with myasthenia gravis, although a strong history of autoimmune disorders is a known risk factor. Our patient's antiretinal antibody panel was unaffected immediately after plasmapheresis treatment. Antibodies to GAPDH and unnamed 38-kDa and 86-kDa proteins were able to pass through the placenta into the fetal circulation, although their effect on the growing fetus is not clear.

Silva, C A; Cocuzza, M; Carvalho, J F; Bonfá, E

2014-01-01

Autoimmune orchitis is characterized by testis inflammation and the presence of specific antisperm antibodies (ASA). It is classified in two categories. Primary autoimmune orchitis is defined by infertility and asymptomatic orchitis associated with ASA (100%) directed to the basement membrane or seminiferous tubules in infertile men, without any systemic disease and usually asymptomatic. Secondary autoimmune orchitis is characterized by symptomatic orchitis and/or testicular vasculiti`s associated with a systemic autoimmune disease, particularly vasculitis. These patients typically demonstrate testicular pain, erythema and/or swelling. ASA in secondary autoimmune orchitis have been reported in up to 50% of patients, especially in systemic lupus erythematosus patients. The pathogenesis of primary as well as secondary autoimmune orchitis is still unknown. Although the etiology is likely to be multifactorial, testicular inflammation, infection or trauma may induce T cell response with pro-inflammatory cytokine production with a consequent blood-testis-barrier permeability alteration, ASA production and apoptosis of spermatocytes and spermatids. ASA is known to cause immobilization and/or agglutination of spermatozoa, which may block sperm-egg interaction resulting in infertility. Assisted reproduction has been used as an efficient option in primary cases and immunosuppressive therapy for secondary autoimmune orchitis, although there is no double-blind, randomized trial to confirm the efficacy of any treatment regimens for these conditions.

Familial autoimmunity and polyautoimmunity in 60 Brazilian Midwest patients with systemic sclerosis

Directory of Open Access Journals (Sweden)

Alex Magno Coelho Horimoto

Full Text Available ABSTRACT Introduction: Systemic sclerosis (SSc is a connective tissue disease of unknown etiology, characterized by a triad of vascular injury, autoimmunity and tissue fibrosis. It is known that a positive family history is the greatest risk factor already identified for the development of SSc in a given individual. Preliminary observation of a high prevalence of polyautoimmunity and of familial autoimmunity in SSc patients support the idea that different autoimmune phenotypes may share common susceptibility variants. Objectives: To describe the frequency of familial autoimmunity and polyautoimmunity in 60 SSc patients in the Midwest region of Brazil, as well as to report the main autoimmune diseases observed in this association of comorbidities. Methods: A cross-sectional study with recruitment of 60 consecutive patients selected at the Rheumatology Department, University Hospital, Medicine School, Federal University of Mato Grosso do Sul (FMUFMS, as well as interviews of their relatives during the period from February 2013 to March 2014. Results: A frequency of 43.3% of polyautoimmunity and of 51.7% of familial autoimmunity in SSc patients was found. Patients with the presence of polyautoimmunity and familial autoimmunity presented primarily the diffuse form of SSc, but this indicator did not reach statistical significance. The autoimmune diseases most frequently observed in polyautoimmunity patients were: Hashimoto's thyroiditis (53.8%, Sjögren's syndrome (38.5%, and inflammatory myopathy (11.5%. The main autoimmune diseases observed in SSc patients' relatives were: Hashimoto's thyroiditis (32.3%, rheumatoid arthritis (22.6%, and SLE (22.6%. The presence of more than one autoimmune disease in SSc patients did not correlate with disease severity or activity. Conclusions: From the high prevalence of coexisting autoimmune diseases found in SSc patients, we stress the importance of the concept of shared autoimmunity, in order to promote a

Primary immunodeficiencies (PIDs) are rare inborn errors of immunity that have a heterogeneous phenotype that can include severe susceptibility to life-threatening infections from multiple pathogens, unique sensitivity to a single pathogen, autoimmune/inflammatory (AI/I) disease, allergies and/or malignancy. We present a diverse cohort of monogenic PID patients with and without AI/I diseases who underwent clinical, genetic and immunological phenotyping. Novel pathogenic variants were identified in IKBKG , CTLA4 , NFKB1 , GATA2 , CD40LG and TAZ as well as previously reported pathogenic variants in STAT3 , PIK3CD , STAT1 , NFKB2 and STXBP2 . AI/I manifestations were frequently encountered in PIDs, including at presentation. Autoimmunity/inflammation was multisystem in those effected, and regulatory T cell (Treg) percentages were significantly decreased compared with those without AI/I manifestations. Prednisolone was used as the first-line immunosuppressive agent in all cases, however steroid monotherapy failed long-term control of autoimmunity/inflammation in the majority of cases and additional immunosuppression was required. Patients with multisystem autoimmunity/inflammation should be investigated for an underlying PID, and in those with PID early assessment of Tregs may help to assess the risk of autoimmunity/inflammation.

Systemic vasculitides constitute a heterogeneous group of diseases. Autoimmunity mediated by B lymphocytes and their humoral effector mechanisms play a major role in ANCA-associated vasculitis (AAV) as well as in non-ANCA associated primary systemic vasculitides and in the different types of autoimmune connective tissue disorders and rheumatoid arthritis. In order to detect autoantibodies in systemic vasculitides, we screened protein macroarrays of human cDNA expression libraries with sera from patients with ANCA-associated and ANCA-negative primary systemic vasculitides. This approach led to the identification of antibodies against progranulin, a 88 kDA secreted glycoprotein with strong anti-inflammatory activity in the course of disease of giant-cell arteritis/polymyalgia rheumatica (14/65), Takayasu's arteritis (4/13), classical panarteritis nodosa (4/10), Behcet's disease (2/6) and in the course of disease in granulomatosis with polyangiitis (31/75), Churg-Strauss syndrome (7/23) and in microscopic polyangiitis (7/19). In extended screenings the progranulin antibodies were also detected in other autoimmune diseases such as systemic lupus erythematosus (39/91) and rheumatoid arthritis (16/44). Progranulin antibodies were detected only in 1 of 97 healthy controls. Anti-progranulin positive patients with systemic vasculitides, systemic lupus erythematosus or rheumatoid arthritis had significant lower progranulin plasma levels, indicating a neutralizing effect. In light of the anti-inflammatory effects of progranulin, progranulin antibodies might exert pro-inflammatory effects thus contributing to the pathogenesis of the respective autoimmune diseases and might serve as a marker for disease activity. This hypothesis is supported by the fact that a positive progranulin antibody status was associated with active disease in granulomatosis with polyangiitis. Copyright © 2012 Elsevier Ltd.

Full Text Available Autoimmune cholangitis (AIC was first described in 1987 as immunocholangitis in three women who presented with signs and symptoms of primary biliary cholangitis (PBC, but who were antimitochondrial (AMA negative and antinuclear antibodies (ANA positive, and responded to immunosuppressive therapy with azathioprine and prednisolone (1. AIC is a rare chronic cholestatic inflammatory disease characterized by the presence of high ANA or smooth muscle antibodies (SMA but AMA seronegativity. Histologically, AIC exhibits bile duct injury (2. In terms of therapeutics, in addition to response to ursodeoxycholic acid, a prompt response to corticosteroids has also been reported in earlier stages, distinguishing it from PBC. Herein the authors describe two cases with mixed signs of PBC and autoimmune hepatitis (AIH. The diagnostic differentiation between these diseases (AIC, PBC and AIH is essential because of the different therapeutic strategies. Our cases highlight the importance of clinician awareness of the autoimmune spectrum of liver diseases.

Etiology of Organ-Specific Autoimmunity: Basic Research and Clinical Implications in IBD

Directory of Open Access Journals (Sweden)

George S Eisenbarth

1996-01-01

Full Text Available Autoimmunity develops in the setting of genetic susceptibility and can be monogenic (eg, autoimmune polyendocrine syndrome type I with Addison’s disease, mucocutaneous candidiasis and hypoparathyroidism, which is autosomal recessive with the causative gene on the tip of chromosome 21 or polygenic (usually with important alleles within the major histocompatibility complex [eg, type I diabetes]. In addition to genetic susceptibility, many autoimmune disorders can be classified into etiological categories (oncogenic, drug-induced, diet-induced, infectious or idiopathic. For most autoimmune disorders there are multiple target autoantigens and, for type I diabetes, a combinatorial approach (eg, expression of at least two autoantibodies of insulin, glutamic acid decarboxylase and/or ICA512/IA-2 is the best predictor of diabetes risk. Finally, antigen-specific therapies hold promise for the prevention and therapy of autoimmunity, eg, parenteral or oral therapy with insulin delays or prevents type I diabetes in animal models, and a small pilot trial of parenteral insulin in humans suggests that such therapy may similarly prevent diabetes in humans.

Autoimmunity and Extrahepatic Manifestations in Treatment-Naïve Children with Chronic Hepatitis C Virus Infection

Directory of Open Access Journals (Sweden)

Giuseppe Indolfi

2012-01-01

Full Text Available Hepatitis C virus (HCV infection has been associated with autoimmunity and extrahepatic manifestations in adults. Few data are available on these topics in children. Nonorgan specific auto-antibodies development is part of the natural course of chronic hepatitis C in children. Smooth muscle autoantibody is the most common autoantibody found, while liver-kidney microsomal type-1 antibody positivity is the most peculiar autoimmune feature of children with HCV infection. The clinical significance of non-organ specific autoantibodies in the course of paediatric chronic hepatitis C is still debated. Autoantibody positivity can be considered neutral for most patients, while it can be associated with negative connotations for others, especially those positive for liver-kidney microsomal type-1 autoantibody. Subclinical hypothyroidism but not autoimmune thyroiditis has been demonstrated in HCV infection in children, while only few cases of HCV-associated membranoproliferative glomerulonephritis have been described. Single reports are available in the literature reporting the anecdotal association between chronic hepatitis C and other extrahepatic manifestations such as myopathy and opsoclonus-myoclonus syndrome. Despite the low incidence of extrahepatic manifestations of chronic hepatitis C in children, overall, available data suggest a careful monitoring.

Secondary Hemophagocytic Syndrome: The Importance of Clinical Suspicion

Directory of Open Access Journals (Sweden)

Cristina Oliveira

2014-01-01

Full Text Available Hemophagocytic syndrome is a rare and potentially fatal disorder characterized by pathological immune activation associated with a primary familial disorder, genetic mutations, or occurring as a sporadic condition. The latter can be secondary to infections, malignancies, or autoimmune diseases. Clinically, patients present signs of severe inflammation, with unremitting fever, cytopenias, spleen enlargement, phagocytosis of bone marrow elements, hypertriglyceridemia, and hypofibrinogenemia. Increased suspicion is determinant to timely initiate treatment in an attempt to alter the natural history. The authors present three clinical cases of this syndrome, with a brief review of the diagnostic criteria and treatment.

Case ascertainment through self-report is a convenient but often inaccurate method to collect information. The purposes of this study were to develop, assess the sensibility, and validate a tool to identify cases of systemic autoimmune rheumatic diseases (SARD) in the outpatient setting. The SARD tool was administered to subjects sampled from specialty clinics. Determinants of sensibility - comprehensibility, feasibility, validity, and acceptability - were evaluated using a numeric rating scale from 1-7. Comprehensibility was evaluated using the Flesch Reading Ease and the Flesch-Kincaid Grade Level. Self-reported diagnoses were validated against medical records using Cohen's κ statistic. There were 141 participants [systemic lupus erythematosus (SLE), systemic sclerosis (SSc), rheumatoid arthritis, Sjögren syndrome (SS), inflammatory myositis (polymyositis/dermatomyositis; PM/DM), and controls] who completed the questionnaire. The Flesch Reading Ease score was 77.1 and the Flesch-Kincaid Grade Level was 4.4. Respondents endorsed (mean ± SD) comprehensibility (6.12 ± 0.92), feasibility (5.94 ± 0.81), validity (5.35 ± 1.10), and acceptability (3.10 ± 2.03). The SARD tool had a sensitivity of 0.91 (95% CI 0.88-0.94) and a specificity of 0.99 (95% CI 0.96-1.00). The agreement between the SARD tool and medical record was κ = 0.82 (95% CI 0.77-0.88). Subgroup analysis by SARD found κ coefficients for SLE to be κ = 0.88 (95% CI 0.79-0.97), SSc κ = 1.0 (95% CI 1.0-1.0), PM/DM κ = 0.72 (95% CI 0.49-0.95), and SS κ = 0.85 (95% CI 0.71-0.99). The screening questions had sensitivity ranging from 0.96 to 1.0 and specificity ranging from 0.88 to 1.0. This SARD case ascertainment tool has demonstrable sensibility and validity. The use of both screening and confirmatory questions confers added accuracy.

Mills’ syndrome: a case report

Full Text Available The syndrome of progressive, ascending or descending hemiplegia, with no significant sensory impairment was first describes by Mills in 1900, which several cases were reported later. However after diagnostic tests and image improvements, the number of reports has shortened. A possible explanation for this shortage is the identification of other diseases that could mimic the clinical picture. Currently, the syndrome has an uncertain nosological status, since it was described based on clinical examination only. We can find this clinical presentation (Mills syndrome in cases of amyotrophic lateral sclerosis (ALS, predominant upper motor neuron amyotrophic lateral sclerosis (UMN-ALS and primary lateral sclerosis (PLS, besides its symptomatic (secondary forms. We describe a case (initial presentation and one year follow-up of progressive ascending hemiplegia with clinical isolated upper neuron signs and normal sensory examination, discussing its nosological status, electromyographic findings, differential diagnosis and prognosis.

Activation-induced cytidine deaminase deficiency causes organ-specific autoimmune disease.

Directory of Open Access Journals (Sweden)

Koji Hase

Full Text Available Activation-induced cytidine deaminase (AID expressed by germinal center B cells is a central regulator of somatic hypermutation (SHM and class switch recombination (CSR. Humans with AID mutations develop not only the autosomal recessive form of hyper-IgM syndrome (HIGM2 associated with B cell hyperplasia, but also autoimmune disorders by unknown mechanisms. We report here that AID-/- mice spontaneously develop tertiary lymphoid organs (TLOs in non-lymphoid tissues including the stomach at around 6 months of age. At a later stage, AID-/- mice develop a severe gastritis characterized by loss of gastric glands and epithelial hyperplasia. The disease development was not attenuated even under germ-free (GF conditions. Gastric autoantigen -specific serum IgM was elevated in AID-/- mice, and the serum levels correlated with the gastritis pathological score. Adoptive transfer experiments suggest that autoimmune CD4+ T cells mediate gastritis development as terminal effector cells. These results suggest that abnormal B-cell expansion due to AID deficiency can drive B-cell autoimmunity, and in turn promote TLO formation, which ultimately leads to the propagation of organ-specific autoimmune effector CD4+ T cells. Thus, AID plays an important role in the containment of autoimmune diseases by negative regulation of autoreactive B cells.

Background. Comorbid autoimmune diseases in MS patients have been studied extensively with controversial results. Moreover, no such data exists for Latin-American MS patients. Methods. We conducted a case-control study aimed to establish the prevalence of autoimmune disorders in a cohort of Argentinean MS patients. Results. There were no significant differences in autoimmune disease prevalence in MS patients with respect to controls. The presence of one or more autoimmune disorders did not increase risk of MS (OR 0.85, 95% CI 0.6-1.3). Discussion. Our results indicate absence of increased comorbid autoimmune disease prevalence in MS patients, as well as of increased risk of MS in patients suffering from other autoimmune disorders.

A Case of Classic Raymond Syndrome

Nicholas George Zaorsky

2012-01-01

Full Text Available Classic Raymond syndrome consists of ipsilateral abducens impairment, contralateral central facial paresis, and contralateral hemiparesis. However, subsequent clinical observations argued on the presentation of facial involvement. To validate this entity, we present a case of classic Raymond syndrome with contralateral facial paresis. A 50 year-old man experienced acute onset of horizontal diplopia, left mouth drooling and left-sided weakness. Neurological examination showed he had right abducens nerve palsy, left-sided paresis of the lower part of the face and limbs, and left hyperreflexia. A brain MRI showed a subacute infarct in the right mid-pons. The findings were consistent with those of classic Raymond syndrome. To date, only a few cases of Raymond syndrome, commonly without facial involvement, have been reported. Our case is a validation of classic Raymond syndrome with contralateral facial paresis. We propose the concept of two types of Raymond syndrome: (1 the classic type, which may be produced by a lesion in the mid-pons involving the ipsilateral abducens fascicle and undecussated corticofacial and corticospinal fibers; and (2 the common type, which may be produced by a lesion involving the ipsilateral abducens fascicle and undecussated corticospinal fibers but sparing the corticofacial fibers.

Boerhaave syndrome - case report

Directory of Open Access Journals (Sweden)

Biljana Radovanovic Dinic

Full Text Available ABSTRACT CONTEXT: Boerhaave syndrome consists of spontaneous longitudinal transmural rupture of the esophagus, usually in its distal part. It generally develops during or after persistent vomiting as a consequence of a sudden increase in intraluminal pressure in the esophagus. It is extremely rare in clinical practice. In 50% of the cases, it is manifested by Mackler's triad: vomiting, lower thoracic pain and subcutaneous emphysema. Hematemesis is an uncommon yet challenging presentation of Boerhaave's syndrome. Compared with ruptures of other parts of the digestive tract, spontaneous rupture is characterized by a higher mortality rate. CASE REPORT: This paper presents a 64-year-old female patient whose vomit was black four days before examination and became bloody on the day of the examination. Her symptoms included epigastric pain and suffocation. Physical examination showed hypotension, tachycardia, dyspnea and a swollen and painful abdomen. Auscultation showed lateral crackling sounds on inspiration. Ultrasound examination showed a distended stomach filled with fluid. Over 1000 ml of fresh blood was extracted by means of nasogastric suction. Esophagogastroduodenoscopy was discontinued immediately upon entering the proximal esophagus, where a large amount of fresh blood was observed. The patient was sent for emergency abdominal surgery, during which she died. An autopsy established a diagnosis of Boerhaave syndrome and ulceration in the duodenal bulb. CONCLUSION: Boerhaave syndrome should be considered in all cases with a combination of gastrointestinal symptoms (especially epigastric pain and vomiting and pulmonary signs and symptoms (especially suffocation.

Full Text Available Objective: To report first-hand narrative experience of autoimmune encephalitis and to briefly review currently available evidence of autoimmune encephalitis in cancer patients treated with immune checkpoint inhibitors. Setting: A case study is presented on the management of a patient who developed autoimmune encephalitis during nivolumab monotherapy occurring after 28 weeks on anti-PD-1 monotherapy (nivolumab 3 mg/kg every 2 weeks for non-small cell lung cancer. Results: No substantial improvement was observed by antiepileptic treatment. After administration of 80 mg methylprednisolone, neurologic symptoms disappeared within 24 h and the patient fully recovered. Conclusions: Immune checkpoint inhibitor treatment can lead to autoimmune encephalitis. Clinical trial data indicate a frequency of autoimmune encephalitis of ≥0.1 to <1% with a higher probability during combined or sequential anti-CTLA-4/anti-PD-1 therapy than during anti-PD-1 or anti-PD-L1 monotherapy. Further collection of evidence and translational research is warranted.

Full Text Available Chikungunya infection has recently re-emerged as an important arthropod-borne disease in Thailand. Recently, Southern Thailand was identified as a potentially endemic area for the chikungunya virus. Here, we report a case of severe musculoskeletal complication, presenting with muscle weakness and swelling of the limbs. During the investigation to exclude autoimmune muscular inflammation, high titers of antinuclear antibody were detected. This is the report of autoimmunity detection associated with an arbovirus infection. The symptoms can mimic autoimmune polymyositis disease, and the condition requires close monitoring before deciding to embark upon prolonged specific treatment with immunomodulators.

Guillain-Barre Syndrome (GBS) is the most common disease resulting in acute diffuse flaccid paralysis. It is an autoimmune disease that can occur at any age. The clinical course is characterized by weakness in the arms and legs, areflexia and the progression of muscle weakness from the lower limbs to the upper limbs. The most common causes of GBS include infections, vaccinations, surgery and some medicines. We present the case of a 48 years old male patient, who developed GBS after undergoing surgery for renal calculus, under spinal anaesthesia. In this case report, we presented a rather rare case of GBS occurring following spinal anaesthesia. (author)

Glutamic acid decarboxylase (GAD65) has been implicated in a number of autoimmune-associated neurologic syndromes, including autoimmune epilepsy. This study categorizes the spectrum of MRI findings in patients with a clinical diagnosis of autoimmune epilepsy and elevated serum GAD65 autoantibodies. An institutional database search identified patients with elevated serum GAD65 antibodies and a clinical diagnosis of autoimmune epilepsy who had undergone brain MRI. Imaging studies were reviewed by three board-certified neuroradiologists and one neuroradiology fellow. Studies were evaluated for cortical/subcortical and hippocampal signal abnormality, cerebellar and cerebral volume loss, mesial temporal sclerosis, and parenchymal/leptomeningeal enhancement. The electronic medical record was reviewed for relevant clinical information and laboratory markers. A study cohort of 19 patients was identified. The majority of patients were female (84%), with a mean age of onset of 27 years. Serum GAD65 titers ranged from 33 to 4415 nmol/L (normal < 0.02 nmol/L). The most common presentation was medically intractable, complex partial seizures with temporal lobe onset. Parenchymal atrophy was the most common imaging finding (47%), with a subset of patients demonstrating cortical/subcortical parenchymal T2 hyperintensity (37%) or abnormal hippocampal signal (26%). No patients demonstrated abnormal parenchymal/leptomeningeal enhancement. The most common MRI finding in GAD65-associated autoimmune epilepsy is disproportionate parenchymal atrophy for age, often associated with abnormal cortical/subcortical T2 hyperintensities. Hippocampal abnormalities are seen in a minority of patients. This constellation of findings in a patient with medically intractable epilepsy should raise the possibility of GAD65 autoimmunity.

AUTOIMMUNE CYTOPENIAS IN CHRONIC LYMPHOCYTIC LEUKEMIA, FACTS AND MYTHS

Directory of Open Access Journals (Sweden)

2013-11-01

Full Text Available CLL has been defined as presence of more than 5000 small mature appearing monoclonal B lymphocytes with a specific immunophenotype in peripheral blood. It is a well-known fact that CLL is associated with autoimmune cytopenias. CLL cells are CD5+ B lymphocytes, and usually are not the “guilty” cells which produce autoantibodies. T cell defect is another characteristic of CLL and the total number of T cells is increased, and there is inversion of the CD4/CD8 ratio. Autoimmune hemolytic anemia (AIHA is the most common autoimmune complication of CLL and has been reported in 10-25% of CLL patients. However, the stage-adjusted estimated rate of AIHA in CLL is about 5%. Conversely, CLL is three times more common in patients who present with AIHA. Direct agglutinin test (DAT is positive in 7-14% of CLL patients but AIHA may also occur in DAT negative patients. Autoimmune thrombocytopenia (AIT is the second most common complication of CLL and has been reported in 2-3% of patients. DAT is positive in AIT but presence of antiplatelet antibodies is neither diagnostic nor reliable. Autoimmune neutropenia (AIN and pure red cell aplasia (PRCA are very rare complications of CLL and like other autoimmune complications of CLL may occur at any clinical stage. It is believed that most case reports of AIN and PRCA in CLL actually belong to large granular lymphocytic leukemia (LGL. Non-hematologic autoimmune complications of CLL including cold agglutinin disease (CAD, paraneoplastic pemphigus (PNP, acquired angioedema, and anti-myelin associated globulin are rare. Before starting any treatment, clinicians should distinguish between autoimmune cytopenias and massive bone marrow infiltration since autoimmune complications of CLL are not necessarily equal to advanced disease with poor prognosis. According to IWCLL guideline, steroids are the mainstay of treatment of simple autoimmunity. Intravenous immunoglobulin (IVIg, cyclosporine, and rituximab are used in

Genetic association, seasonal infections and autoimmune basis of narcolepsy

Singh, Abinav Kumar; Mahlios, Josh; Mignot, Emmanuel

2014-01-01

In recent years, a growing number of potential autoimmune disorders affecting neurons in the central nervous system have been identified, including narcolepsy. Narcolepsy is a lifelong sleep disorder characterized by excessive daytime sleepiness with irresistible sleep attacks, cataplexy (sudden bilateral loss of muscle tone), hypnagogic hallucinations, and abnormalities of Rapid Eye Movement sleep. Narcolepsy is generally a sporadic disorder and is caused by the loss of hypocretin (orexin)-producing neurons in the hypothalamus region of the brain. Studies have established that more than 90% of patients have a genetic association with HLA DQB1*06:02. Genome-wide association analysis shows a strong association between narcolepsy and polymorphisms in the TCRα locus and weaker associations within TNFSF4 (also called OX40L), Cathepsin H and the P2RY11-DNMT1 (purinergic receptor subtype P2Y11 to DNMT1, a DNA methytransferase) loci, suggesting an autoimmune basis. Mutations in DNMT1 have also been reported to cause narcolepsy in association with a complex neurological syndrome, suggesting the importance of DNA methylation in the pathology. More recently, narcolepsy was identified in association with seasonal streptococcus, H1N1 infections and following AS03-adjuvanted pH1N1 influenza vaccination in Northern Europe. Potential immunological pathways responsible for the loss of hypocretin producing neurons in these cases may be molecular mimicry or bystander activation. Specific autoantibodies or T cells cross-reactive with hypocretin neurons have not yet been identified, however, thus narcolepsy does not meet Witebsky’s criteria for an autoimmune disease. As the brain is not an easily accessible organ, mechanisms of disease initiation and progression remain a challenge to researchers. PMID:23497937

Full Text Available Most of the studies have shown a higher risk for subclinical and clinical hypothyroidism, antithyroid autoantibodies [overall antithyroid peroxidase antibodies (TPOAb], and in general, thyroid autoimmunity, overall in the female gender in patients with sarcoidosis (S. A significantly higher prevalence of clinical hypothyroidism and Graves’ disease was also described in female S patients with respect to controls. Gallium-67 (Ga-67 scyntigraphy in S patients, in the case of thyroid uptake, suggests the presence of aggressive autoimmune thyroiditis and hypothyroidism. For this reason, ultrasonography and thyroid function should be done in the case of Ga-67 thyroid uptake. In conclusion, thyroid function, TPOAb measurement, and ultrasonography should be done to assess the clinical profile in female S patients, and the ones at high risk (female individuals, with TPOAb positivity, and hypoechoic and small thyroid should have periodically thyroid function evaluations and suitable treatments.

RS3PE syndrome (Remitting Seronegative Symmetrical Synovitis with Pitting Edema Syndrome) is one of the disorders which present as polyarthritis. It is important to be aware of RS3PE syndrome when encountering elderly patients with polyarthritis who are negative for rheumatoid factor. We report 4 cases of RS3PE syndrome. All cases shared common clinical findings, such as acute onset, symmetrical polyarthritis, pitting edema of the hands and feet, and being negative for rheumatoid factor in serum. Treatment with corticosteroid was very effective in all cases. However, two patients showed a deteriorated clinical condition during the tapering of corticosteroid. Corticosteroid should be tapered off cautiously in patients with RS3PE syndrome. (author)

Novacek Gottfried

2006-09-01

Full Text Available Abstract Plummer-Vinson or Paterson-Kelly syndrome presents as a classical triad of dysphagia, iron-deficiency anemia and esophageal webs. Exact data about epidemiology of the syndrome are not available; the syndrome is extremely rare. Most of the patients are white middle-aged women, in the fourth to seventh decade of life but the syndrome has also been described in children and adolescents. The dysphagia is usually painless and intermittent or progressive over years, limited to solids and sometimes associated with weight loss. Symptoms resulting from anemia (weakness, pallor, fatigue, tachycardia may dominate the clinical picture. Additional features are glossitis, angular cheilitis and koilonychia. Enlargement of the spleen and thyroid may also be observed. One of the most important clinical aspects of Plummer-Vinson syndrome is the association with upper alimentary tract cancers. Etiopathogenesis of Plummer-Vinson syndrome is unknown. The most important possible etiological factor is iron deficiency. Other possible factors include malnutrition, genetic predisposition or autoimmune processes. Plummer-Vinson syndrome can be treated effectively with iron supplementation and mechanical dilation. In case of significant obstruction of the esophageal lumen by esophageal web and persistent dysphagia despite iron supplementation, rupture and dilation of the web are necessary. Since Plummer-Vinson syndrome is associated with an increased risk of squamous cell carcinoma of the pharynx and the esophagus, the patients should be followed closely.

The aim of the paper was to present the case of a patient who developed acute psychotic symptoms on her visit to Jerusalem. The analysis of the clinical case and medical history. The presented 62-year-old women with a history of previous psychiatric disorder arrived with her husband to Jerusalem as a part of organised touristic group. She developed acute psychotic reaction through some stages characteristic for the third type of Jerusalem syndrome. Symptoms resolved completely soon after returning to Poland and admission to the hospital where an antipsychotic treatment was performed. Despite the rare occurrence of this phenomenon, it is worth noting that we can divide Jerusalem syndrome into three types depending on its clinical course, patient's history of previous psychiatric disorders and this division has some clinical implications. This syndrome can be also considered in the context of some factors connected with travelling in general which may be responsible for psychiatric disturbances occurring among travelers. The course of psychiatric disturbances in the presented patient resembled the third type of Jerusalem syndrome despite her past psychiatric history and probably travelling caused her decompensations. In clinical practice we have to remember that in case of the patients with a known psychiatric history, clinical evaluation may be useful before travelling. In previously healthy patients developing the third type of the Jerusalem syndrome early intervention and separation from Jerusalem and its holy places and their contact with family are crucial for soon recovery.

Toll-Like Receptor Pathways in Autoimmune Diseases.

2016-02-01

Autoimmune diseases are a family of chronic systemic inflammatory disorders, characterized by the dysregulation of the immune system which finally results in the break of tolerance to self-antigen. Several studies suggest that Toll-like receptors (TLRs) play an essential role in the pathogenesis of autoimmune diseases. TLRs belong to the family of pattern recognition receptors (PRRs) that recognize a wide range of pathogen-associated molecular patterns (PAMPs). TLRs are type I transmembrane proteins and located on various cellular membranes. Two main groups have been classified based on their location; the extracelluar group referred to the ones located on the plasma membrane while the intracellular group all located in endosomal compartments responsible for the recognition of nucleic acids. They are released by the host cells and trigger various intracellular pathways which results in the production of proinflammatory cytokines, chemokines, as well as the expression of co-stimulatory molecules to protect against invading microorganisms. In particular, TLR pathway-associated proteins, such as IRAK, TRAF, and SOCS, are often dysregulated in this group of diseases. TLR-associated gene expression profile analysis together with single nucleotide polymorphism (SNP) assessment could be important to explain the pathomechanism driving autoimmune diseases. In this review, we summarize recent findings on TLR pathway regulation in various autoimmune diseases, including Sjögren's syndrome (SS), systemic lupus erythematosus (SLE), multiple sclerosis (MS), rheumatoid arthritis (RA), systemic sclerosis (SSc), and psoriasis.

Churg-Strauss syndrome (CSS) is a rare autoimmune disease with small-vessel vasculitis. Neurological manifestation of CSS is common. Central nervous system is less frequently involved than that of peripheral nervous system. We report a case of 60-year-old man who presented with acute onset of right hemiparesis and impaired cognition. The presence of hypereosinophilia, asthma, sinusitis and extravascular eosinophil accumulation led to the diagnosis of Churg-Strauss syndrome. Brain magnetic resonance imaging (MRI) revealed multiple infarcts in bilateral cerebral and cerebellar hemispheres. The neurophysiology study did not reveal peripheral neuropathy. The patient was effectively treated with methylprednisolone, cyclophosphamide and warfarin. Symptoms and signs of central nervous system can be the initial neurological manifestation of CSS patients. CSS should be considered while patients have stroke and hypereosinophilia. In our patient, there is a good response to timely steroid, immunosuppressant and anticoagulant therapies.

2013-05-01

The tubulo-interstitial nephritis and uveitis (TINU) syndrome, first described in 1975, is a rare disease most probably of autoimmune origin that is characterized by unilateral or bilateral uveitis and tubulointerstitial nephritis. Most patients are adolescents and it is sometimes associated with other autoimmune diseases, such as spondyloarthritis, rheumatoid arthritis and hyperthyroidosis. This article reports the case of a 43-year-old female patient who presented with refractory recurrent bilateral uveitis despite therapy with high doses of corticosteroids in combination with cyclosporin. When the patient was referred to this hospital for rheumatological examination after almost 1 year of therapy, mild renal insufficiency and proteinuria were found. The kidney biopsy revealed interstitial nephritis, partly crescent-shaped and partly chronic. A diagnosis of TINU syndrome was made and treatment with adalimumab in combination with methotrexate was started. The favorable clinical outcome indicated that tumor necrosis factor (TNF) alpha may play an important role in the pathogenesis of TINU syndrome.

Full Text Available Acanthosis nigricans (AN is a dermatosis characterized by velvety, papillomatous, brownish-black, hyperkeratotic plaques, typically on the intertriginous surfaces and neck. The majority (80% of AN occurs idiopathically or in benign conditions such as endocrinopathies like diabetes mellitus, polycystic ovary syndrome; metabolic syndrome and/or heritable disease. Malignancy-associated AN is rare. AN may rarely be associated with autoimmune diseases including systemic lupus erythematosus, due to antibodies to the insulin receptor, so-called type B insulin resistance. Here we report a case of AN in a case of diffuse progressive systemic sclerosis without evidence of insulin resistance.

2011-01-01

Full Text Available Sweet's syndrome is an acute febrile neutrophilic dermatosis which usually presents as an idiopathic disorder but can also be drug induced, associated with hematopoetic malignancies and myelodysplastic disorders, and more, infrequently, observed in autoimmune disorders. Sweet's syndrome has been reported in three cases of neonatal lupus, three cases of hydralazine-induced lupus in adults, and in nine pediatric and adult systemic lupus erythematosus (SLE patients. We describe three additional adult cases of Sweet's associated with SLE and provide a focused review on nondrug-induced, nonneonatal SLE and Sweet's. In two of three new cases, as in the majority of prior cases, the skin rash of Sweet's paralleled underlying SLE disease activity. The pathogenesis of Sweet's remains elusive, but evidence suggests that cytokine dysregulation may be central to the clinical and pathological changes in this condition, as well as in SLE. Further research is needed to define the exact relationship between the two conditions.

Full Text Available Introduction. Autoimmune encephalitis (AE is a clinically challenging diagnosis with nonspecific neurological symptoms. Prompt diagnosis is important and often relies on neuroimaging. We present a case series of AE highlighting the importance of an early [18F]-fluoro-deoxy-glucose positron emission tomography (FDG-PET scan. Methods. Retrospective review of seven consecutive cases of autoimmune encephalitis. Results. All patients had both magnetic resonance imaging (MRI and FDG-PET scans. Initial clinical presentations included altered mental status and/or new onset seizures. Six cases had serum voltage-gated potassium channel (VGKC antibody and one had serum N-methyl-D-aspartate (NMDA antibody. MRI of brain showed mesial temporal lobe hyperintensity in five cases of VGKC. The other two patients with VGKC or NMDA AE had restiform body hyperintensity on MRI brain or a normal MRI, respectively. Mesial temporal lobe hypermetabolism was noted in three cases on FDG-PET, despite initial unremarkable MRI. Malignancy workup was negative in all patients. Conclusion. A high index of suspicion for AE should be maintained in patients presenting with cognitive symptoms, seizures, and limbic changes on neuroimaging. In cases with normal initial brain MRI, FDG-PET can be positive. Additionally, extralimbic hyperintensity on MRI may also be observed.

ROHHAD syndrome (rapid-onset obesity with hypothalamic dysregulation, hypoventilation, and autonomic dysregulation) is a rare and complex disease, presenting in previously healthy children at the age of 2-4 years. Up to 40% of cases are associated with neural crest tumours. We present the case of a 2-year-old girl with symptoms of rapidly progressing obesity, who a few months later developed hypothalamic dysfunction with severe electrolyte imbalance, behaviour disorder, hypoventilation, and severe autonomic dysregulation, among other symptoms. Although the pathophysiology of this syndrome remains unclear, an autoimmune hypothesis has been proposed for ROHHAD. Therefore, after obtaining a limited response to intravenous immunoglobulins, we decided to test the response to a high dose cyclophosphamide (low dose was not effective either). Unfortunately our patient experienced many severe complications (among them central pontine myelinolysis, from which the patient recovered, and failure to wean from the ventilator requiring tracheostomy and long term ventilation) that required a prolonged ICU stay. Although her behaviour improved, our patient unfortunately died suddenly at home at the age of 5 due to respiratory pathology. ROHHAD syndrome is a rare and little-known disease which requires a multidisciplinary approach because it involves complex symptoms and multiple organ system involvement. Alveolar hypoventilation should be identified early and appropriate treatment should be started promptly for the best possible outcome. Immunomodulatory treatment with immunoglobulins, cyclophosphamide, or rituximab has previously resulted in symptom improvement in some cases. Because of the low incidence of the syndrome, multi-centre studies must be carried out in order to gather more accurate information about ROHHAD pathophysiology and design an appropriate therapeutic approach.

Structural congenital heart disease (CHD) has not previously been linked to autoimmunity. In our study, we developed an autoimmune model of structural CHD that resembles hypoplastic left heart syndrome (HLHS), a life-threatening CHD primarily affecting the left ventricle. Because cardiac myosin (CM) is a dominant autoantigen in autoimmune heart disease, we hypothesized that immunization with CM might lead to transplacental passage of maternal autoantibodies and a prenatal HLHS phenotype in exposed fetuses. Elevated anti-CM autoantibodies in maternal and fetal sera, as well as IgG reactivity in fetal myocardium, were correlated with structural CHD that included diminished left ventricular cavity dimensions in the affected progeny. Further, fetuses that developed a marked HLHS phenotype had elevated serum titers of anti-β-adrenergic receptor Abs, as well as increased protein kinase A activity, suggesting a potential mechanism for the observed pathological changes. Our maternal-fetal model presents a new concept linking autoimmunity against CM and cardiomyocyte proliferation with cardinal features of HLHS. To our knowledge, this report shows the first evidence in support of a novel immune-mediated mechanism for pathogenesis of structural CHD that may have implications in its future diagnosis and treatment.

Lemierre syndrome: two cases and a review.

Syed, Mohammed Iqbal; Baring, David; Addidle, Michael; Murray, Craig; Adams, Calum

2007-09-01

Lemierre syndrome is usually caused by an acute oropharyngeal infection in previously healthy young adults, resulting in thrombophlebitis of the internal jugular vein, leading to metastatic septic embolization and bacteraemia. The usual organism is Fusobacterium necrophorum. Lemierre syndrome, not so long ago labeled as the "forgotten disease," is on the rise. Today with increasing antibiotic-resistant organisms, and decreasing awareness of the syndrome, subsequent re-emergence of this "forgotten disease" is becoming more common in clinical settings. Lemierre syndrome has significant morbidity. Cranial nerve complications associated with the condition have been increasingly diagnosed in the last few years. Looking back at literature on Lemierre syndrome, there have been review articles in medical and microbiology journals but rarely in otolaryngology journals. By presenting our cases we demonstrate the diverse presentations and severity of the illness. A review of the literature and a case report on two cases seen in our institution in the last year are presented. Each of these had varied presentations and neurologic complications-one developed 9th to 12th cranial nerve palsies and Horner syndrome, which have not been described in previous literature, and the other developed polyneuropathy and a frontal lobe infarct among other multisystem complications. Diagnosis of Lemierre syndrome is not always straightforward as clinical features are variable and blood cultures are often negative. Awareness of the syndrome and a high degree of suspicion are needed.

The association between the signal transducer and activator of transcription 4 (STAT4) gene rs7574865 single nucleotide polymorphism and different autoimmune diseases remains controversial and ambiguous. We conducted this study to investigate whether combined evidence shows the association between STAT4 rs7574865 polymorphism and autoimmune diseases. Comprehensive Medline search and review of the references were used to get the relevant reports published before September 2011. Meta-analysis was conducted for genotype T/T (recessive effect), T/T + G/T (dominant effect) and T allele in random effects models. 40 studies with 90 comparisons including 32 systemic lupus erythematosus (SLE), 19 rheumatoid arthritis (RA), 3 type 1 diabetes (T1D), 11 Systemeric Sclerosis (SSc), 4 inflammatory bowed diseases (IBD), 3 Primary Sjogren's syndrome (pSS), 4 juvenile idiopathic arthritis (JIA), 2 Primary antiphospholipid syndrome (APS), 1 Autoimmune thyroid diseases, 1 multiple sclerosis, 1 Psoriasis, 1 Wegener's granulomatosis, 1 Type 2 diabetes, and 1 giant cell arteritis disease were available for this meta-analysis. The overall odds ratios for rs7574865 T-allele significantly increased in SLE, RA, T1D, SSc, JIA, and APS (OR = 1.56, 1.25, 1.13, 1.34, 1.25, and 2.15, respectively, P rs7574865 T allele confers susceptibility to SLE, RA, T1D, SSc, JIA, APS, IBD-UC, and pSS patients, supporting the hypothesis of association between STAT4 gene polymorphism and subgroup of autoimmune diseases.

Full Text Available Psoriasis (PsO is a chronic relapsing/remitting autoimmune skin disease, associated with an increased risk of other autoimmune disorders. Psoriatic arthritis (PsA is a chronic inflammatory arthritis occurring approximately in 30% of PsO patients. Sporadic cases of association between PsO and autoimmune thyroid disorders (AITDs have been reported. However, two different recent studies did not find any association between them. In patients with PsO and PsA, an association with AITD has been shown by most of the studies in adults, but not in the juvenile form. In PsA women and men, thyroid autoimmunity [positive antithyroid peroxidase (AbTPO antibodies, hypoechoic thyroid pattern] and subclinical hypothyroidism were more prevalent than in the general population. An association has been shown also in patients with PsO, arthritis, and inflammatory bowel disease, who have more frequently AITD. A Th1 immune predominance has been shown in early PsO, and PsA, with high serum CXCL10 (Th1 prototype chemokine, overall in the presence of autoimmune thyroiditis. This Th1 immune predominance might be the immunopathogenetic base of the association of these disorders. A raised incidence of new cases of hypothyroidism, thyroid dysfunction, positive AbTPO, and appearance of a hypoechoic thyroid pattern in PsA patients, especially in women, has been shown recently, suggesting to evaluate AbTPO levels, thyroid function, and thyroid ultrasound, especially in PsA women. Thyroid function follow-up and suitable treatments should be performed regularly in PsA female patients at high risk (thyroid-stimulating hormone within the normal range but at the higher limit, positive AbTPO, hypoechoic, and small thyroid.

Oral candidiasis (OC) is a potential oral complication in Sjögren's syndrome (SS). Some studies indicate that the low stimulated salivary flow and not low unstimulated salivary flow is associated with OC in SS, while others report that the underlying autoimmune disorders contribute to OC, based solely on correlation coefficients. Given the conflicting and limited existing evidence, we purposed to ascertain the role of both salivary gland dysfunction (hyposalivation based on unstimulated and stimulated flow rates) and autoimmunity (SS, other autoimmune disorders) in OC among those with SS, other salivary gland dysfunction, and non-salivary gland dysfunction controls (NSGD). A nested case-control study was designed within a larger NIH/NIDCR cohort. Descriptive analyses, nonparametric tests, comparative analyses, and multivariate logistic regression analyses were undertaken. Data on 1526 subjects (701 SS, 247 ISS, 355 Sicca, and 223 NSGD) were obtained from the source cohort of 2046 and analyzed for this study. The median whole unstimulated salivary flow rate (WUS, ml 15 min -1 ) was lower in SS (0.8, interquartile range (IQR) 1.8) compared to ISS (5.5, IQR: 5.2, P salivary flow rate (TSS, ml 15 min -1 ) was lowest in SS (7.0, IQR: 12.4, P diabetes mellitus (4.2, 95%CI: 1.2-15.2, P = 0.02) were independent predictors of OC; females had a lower risk than males (OR = 0.29, 95%CI: 0.13-0.67, P = 0.004). Age, race, anti-SSA/SSB autoantibodies, focus score, other medications, anxiety, fatigue, cigarette smoking, alcohol, and caffeine use were not associated with oral candidiasis. Salivary gland dysfunction (hyposalivation with WUS being a stronger predictor than TSS) and autoimmunity (SS, other autoimmune disorders, medications, i.e., DMARDS) are both independent predictors of OC. Diabetes mellitus is an independent predictor of OC among those with salivary gland dysfunction. Our findings suggest that these independent predictors should be considered in the

Stem cell therapy for severe autoimmune diseases

Marmont Alberto M.

2002-01-01

Full Text Available Intense immunosuppresion followed by alogenic or autogenic hematopoietic stem cell transplantation is a relatively recent procedure which was used for the first time in severe, refractory cases of systemic lupus erythematosus. Currently three agressive procedures are used in the treatment of autoimmune diseases: high dose chemotherapy without stem cell rescue, intense immunosuppression with subsequent infusion of the alogenic hematopoietic stem cell transplantation combined with or without the selection of CD34+ cells, and the autogenic hematopoietic stem cell transplantation. Proof of the graft-versus-leukemia effect observed define SCT as a form of immunotherapy, with additional evidence of an similar Graft-vs-Autoimmunity effect which is suggestive of a cure for autoimmune diseases in this type of therapy. The use of alogenic SCT improved due to its safety compared to autogenic transplantations. In this report, data of multiply sclerosis and systemic lupus erythematosus are reported, with the conclusion that Immunoablation followed by SCT is clearly indicated in such cases.

Full Text Available Although the role of interleukin-2 (IL-2 and interferon gamma (gIFN is still poorly understood in hyperthyroid diseases, it is reasonable to assume that these cytokines may be present at higher levels in Graves' disease (GD than in other primarily non-autoimmune thyroid diseases. In order to look for an easy method to distinguish GD from primarily non-autoimmune causes of hyperthyroidism, we compared 13 healthy individuals with 21 treated and untreated hyperthyroid GD patients and with 19 patients with hyperthyroidism due to other etiologies: 7 cases of multinodular goiter, 5 cases of excessive hormone replacement and 7 cases of amiodarone-associated hyperthyroidism. All patients presented low TSH levels and a dubious clinical thyroid state. We found a good correlation between TSH and serum IL-2 levels (r = 0.56; PgIFN (P<0.01 levels were lower in the hyperthyroid group of patients than in control subjects, suggesting a depressed TH1 pattern in the T-cell subset of hyperthyroid patients. GD had normal IL-2 levels, while patients with other forms of thyrotoxicosis presented decreased IL-2 levels (P<0.05. There was no difference between treated and untreated GD patients. We suggest that the direct measurement of serum IL-2 level may help to confirm hyperthyroidism caused by GD.

We report a patient with a seronegative autoimmune panencephalitis, adding a subtype to the emerging spectrum of seronegative autoimmune encephalitis, and we review the sparse literature on isolated psychiatric presentations of autoimmune encephalitis. (A PubMed search for "seronegative autoimmune encephalitis," "nonvasculitic autoimmune inflammatory meningoencephalitis," and related terms revealed VGKC)-complex, N-methyl-D-aspartate receptor (NMDAR), and glutamic acid decarboxylase (GAD) autoantibodies. We excluded genetic, metabolic, paraneoplastic, degenerative, and infectious etiologies. The patient's symptoms remitted fully with immune therapy, but recurred in association with widespread bihemispheric brain lesions. Brain biopsy revealed mild nonvasculitic inflammation and prominent vascular hyalinization. Immune therapy with plasma exchanges cleared the MRI abnormalities but, 10 years after onset, the patient still suffers neuropsychiatric sequelae. We conclude that autoimmune panencephalitis seronegative for VGKC-complex, NMDAR, and GAD autoantibodies is a subtype of autoimmune encephalitis that can present with pure neuropsychiatric features and a normal brain MRI. Immunologic mechanisms may account for psychiatric symptoms in a subset of patients now diagnosed with classical psychotic disorders. Delay in starting immune therapy can lead to permanent neuropsychiatric sequelae. We propose a standardized classification system for the autoimmune encephalitides, integrating earlier pathology-oriented terms with more recently defined serologic and clinical phenotypes.

The utility of immunotherapy, such as pembrolizumab, is becoming essential in the treatment of certain cancers. Pembrolizumab works through binding of programmed cell death 1 receptor that blocks the binding of the programmed cell death ligand 1 and is commonly used in non-small cell lung cancer and melanoma. Pembrolizumab has been reported to be associated with multiple adverse reactions such as pneumonitis, colitis, hepatitis, hypophysitis, hyperthyroidism, hypothyroidism, nephritis, and type 1 diabetes; however, pembrolizumab causing type 1 diabetes was only reported in 0.1% of the patients in clinical trials. A review of the literature generated 1,001 unique citations of which six reported cases of autoimmune diabetes associated with pembrolizumab were selected and compared. Review of the cases showed no sexual predilection and the average age of onset was 58 years old. The majority of the patients were treated for melanoma (5/6 cases), initially presented with diabetic ketoacidosis (4/6 cases), and had at one point taken ipilimumab (4/6 cases). There was no association found between the number of treatments received and the development of diabetes. With the increasing use of pembrolizumab in cancer treatment regular blood glucose monitoring during treatment, especially in patients who had also taken ipilimumab, may prevent the onset of this life-threatening complication.

Full Text Available Benedikt syndrome is a rare midbrain syndrome which is associated with the damage of the median mesencephalic tegmentum. The most common etiology of this syndrome is ischemic stroke. The occlusion of the posterior cerebral artery or the paramedian branches of the basilar artery results with the ischemia of this midbrain territory. Ipsilateral occulomotor cranial nerve palsy, contralateral hemiparesis, hemihypoesthesia, hemiataxia and korea or tremor are the clinical symptoms of this syndrome. In this article, we reported a case of Benedikt syndrome with an etiologic cause of cardioembolic stroke, who was diagnosed by the neurological examination and neuroradiological findings.

Autoimmune diseases (ADs) represent a heterogeneous group of disorders that affect specific target organs or multiple organ systems. These conditions share common immunopathogenic mechanisms (i.e., the autoimmune tautology), which explain the clinical similarities they have among them as well as their familial clustering (i.e., coaggregation). As part of the autoimmune tautology, the influence of environmental exposure on the risk of developing ADs is paramount (i.e., the autoimmune ecology). In fact, environment, more than genetics, shapes immune system. Autoimmune ecology is akin to exposome, that is all the exposures - internal and external - across the lifespan, interacting with hereditary factors (both genetics and epigenetics) to favor or protect against autoimmunity and its outcomes. Herein, we provide an overview of the autoimmune ecology, focusing on the immune response to environmental agents in general, and microbiota, cigarette smoking, alcohol and coffee consumption, socioeconomic status (SES), gender and sex hormones, vitamin D, organic solvents, and vaccines in particular. Inclusion of the autoimmune ecology in disease etiology and health will improve the way personalized medicine is currently conceived and applied.

Galectin-3 in autoimmunity and autoimmune diseases.

Galectin-3 (gal-3) is a β-galactoside-binding lectin, which regulates cell-cell and extracellular interactions during self/non-self-antigen recognition and cellular activation, proliferation, differentiation, migration and apoptosis. It plays a significant role in cellular and tissue pathophysiology by organizing niches that drive inflammation and immune responses. Gal-3 has some therapeutic potential in several diseases, including chronic inflammatory disorders, cancer and autoimmune diseases. Gal-3 exerts a broad spectrum of functions which differs according to its intra- or extracellular localization. Recombinant gal-3 strategy has been used to identify potential mode of action of gal-3; however, exogenous gal-3 may not reproduce the functions of the endogenous gal-3. Notably, gal-3 induces monocyte-macrophage differentiation, interferes with dendritic cell fate decision, regulates apoptosis on T lymphocytes and inhibits B-lymphocyte differentiation into immunoglobulin secreting plasma cells. Considering the influence of these cell populations in the pathogenesis of several autoimmune diseases, gal-3 seems to play a role in development of autoimmunity. Gal-3 has been suggested as a potential therapeutic agent in patients affected with some autoimmune disorders. However, the precise role of gal-3 in driving the inflammatory process in autoimmune or immune-mediated disorders remains elusive. Here, we reviewed the involvement of gal-3 in cellular and tissue events during autoimmune and immune-mediated inflammatory diseases. © 2015 by the Society for Experimental Biology and Medicine.

To evaluate the relationship between resilience and clinical outcomes in patients with autoimmune rheumatic diseases. Focus groups, individual interviews, and chart reviews were done to collect data on 188 women with autoimmune rheumatic diseases, namely rheumatoid arthritis (n=51), systemic lupus erythematosus (n=70), systemic sclerosis (n=35), and Sjögren's syndrome (n=32). Demographic, clinical, and laboratory variables were assessed including disease activity by patient reported outcomes. Resilience was evaluated by using the Brief Resilience Scale. Bivariate, multiple linear regression, and classification and regression trees were used to analyse data. Resilience was influenced by age, duration of disease, and socioeconomic status. Lower resilience scores were observed in younger patients (50years) had higher resilience scores regardless of socioeconomic status. There was no influence of disease activity on resilience. A particular behaviour was observed in systemic sclerosis in which patients with high socioeconomic status and regular physical activity had higher resilience scores. Resilience in patients with autoimmune rheumatic diseases is a continuum process influenced by age and socioeconomic status. The ways in which these variables along with exercise influence resilience deserve further investigation. Copyright © 2017 Société française de rhumatologie. Published by Elsevier SAS.

We report a case of histopathologically proven autoimmune pancreatitis in an 11-year-old boy. Abdominal US and MRI showed a focal swelling of the pancreatic head, the latter also showing delayed contrast enhancement. There was diffuse irregular pancreatic duct narrowing, compression of the intrapancreatic common bile duct, and mild proximal biliary dilatation on MR cholangiopancreatography. Laboratory results revealed normal serum IgG and subclass 4 with negative autoimmune antibodies, and slightly elevated carbohydrate antigen 19-9. This highlights the differentiation of autoimmune pancreatitis from pancreatic head cancer and, to a lesser extent, other forms of pancreatitis in children. (orig.)

In infants under 3 years of age acquired primary hypothyroidism caused by autoimmune thyroiditis is very rare. Hypothyroidism can manifest with different signs and symptoms and has a wide range of presentations from subclinical hypothyroidism to overt form. We describe a child with acquired autoimmune thyroiditis during a very early period of life and with a severe hypothyroidism presentation. A 22-month-old white male patient with normal neonatal screening presented with a six-month history of asthenia and cutaneous pallor. At general clinical and biochemical exams he showed weight gain, statural growth deceleration, poor movements, sleepy expression, instability while walking, myxoedema, bradycardia, open anterior fontanelle, changes in the face habitus, macrocytic anaemia, ascites, and high CPK, creatinine and cholesterol levels. Acquired autoimmune thyroiditis was the final diagnosis. The thyroxine replacement therapy normalized all the clinical and biochemical abnormalities but at the age of 30 months his mental age showed a delay of 6 months. Our case could give useful learning points: i) although the screening for congenital hypothyroidism is routinely performed, a severe hypothyroidism (for example due to autoimmune thyroiditis) can anyway occur early in life and the clinicians should consider this possibility; ii) hypothyroidism can have a misleading and multi-face clinical presentation; iii) anemia, rhabdomyolysis and high creatinine levels should always include the hypothyroidism in the differential diagnosis; iv) thyroxine replacement therapy is able to revert all the clinical manifestations related to the hypothyroidism; v) evaluating the patient's previous pictures could play an important role in resolving a diagnostic conundrum.

More than a century ago, Ortner described a case of cardiovocal syndrome wherein he attributed a case of left vocal fold immobility to compression of the recurrent laryngeal nerve by a dilated left atrium in a patient with mitral valve stenosis. Since then, the term Ortner's syndrome has come to encompass any nonmalignant, cardiac, intrathoracic process that results in embarrassment of either recurrent laryngeal nerve-usually by stretching, pulling, or compression; and causes vocal fold paralysis. Not surprisingly, the left recurrent laryngeal nerve, with its longer course around the aortic arch, is more frequently involved than the right nerve, which passes around the subclavian artery.
