Physicians across the United States are engaged in training in the identification, isolation, and initial care of patients with Ebola. Some will be asked to do more. The issue this viewpoint will address is the moral obligation of physicians to participate in these activities. In order to do so the implicit contract between society and its physicians will be considered, as will many of the arguments that are redolent of those that were litigated 30 years ago when acquired immune deficiency syndrome (AIDS) was raising public fears to similar levels, and some physicians were publically proclaiming their unwillingness to render care to those individuals. We will build the case that if steps are taken to reduce risks-optimal personal protective equipment and training-to what is essentially the lowest possible level then rendering care should be seen as obligatory. If not, as in the AIDS era there will be an unfair distribution of risk, with those who take their obligations seriously having to go beyond their fair measure of exposure. It would also potentially undermine patients' faith in the altruism of physicians and thereby degrade the esteem in which our profession is held and the trust that underpins the therapeutic relationship. Finally there is an implicit contract with society. Society gives tremendously to us; we encumber a debt from all society does and offers, a debt for which recompense is rarely sought. The mosaic of moral, historical, and professional imperatives to render care to the infected all echoes the words of medicine's moral leaders in the AIDS epidemic. Arnold Relman perhaps put it most succinctly, "the risk of contracting the patient's disease is one of the risks that is inherent in the profession of medicine. Physicians who are not willing to accept that risk…ought not be in the practice of medicine." Copyright © 2015 Elsevier Inc. All rights reserved.

People with acquired immune deficiency syndrome (AIDS) develop ischemic stroke through distinct mechanisms. These include infections such as syphilis, tuberculosis, varicella, and other conditions such as cocaine abuse, endocarditis, and hypercoagulability. The effect of improved awareness, detection, and treatment with highly active antiretroviral therapy (HAART) on the incidence and outcome of AIDS patients with stroke is unknown. Data from the Nationwide Inpatient Sample from 1995 to 2010 were analyzed. Patients with ischemic stroke and AIDS were identified using ICD-9 (International Classification of Diseases) codes. Time trends for demographics, survival, and frequency of AIDS-associated conditions were analyzed. Proportion of AIDS among stroke patients increased significantly during the study. Median age of all strokes decreased from 75 years in 1995 to 72 years in 2010. Conversely, median age for men with stroke and AIDS increased from 43 years to 53 years; and for women with stroke and AIDS, from 41 years to 51 years. Death rates from stroke in the AIDS patients declined. In recent years, the death rates from stroke are similar to patients without HIV/AIDS. Stroke patients with AIDS had increased odds of syphilis (odds ratio [OR]: 33.50), varicella (OR: 48.34), tuberculosis (OR: 137.48), endocarditis (OR: 5.19), cocaine abuse (OR: 26.05), and hypercoagulability (OR: 4.82). In the HAART era, the median age of incident stroke in AIDS has increased and the mortality from stroke has improved. Research should focus on optimal management of dyslipidemia while on HAART. Whether HAART can reduce the incidence and improve survival of stroke needs to be explored. Copyright © 2017 National Stroke Association. Published by Elsevier Inc. All rights reserved.

Refractory and relapsing crytocococcosis in acquired immune deficiency syndrome (AIDS) patients have a poor prognosis. The risk factors for this complicated infection course were evaluated by comparing refractory and/or relapsing cryptococcosis in human immunodeficiency virus-coinfected patients (cohort 1) with another group of AIDS patients who adequately responded to antifungals (cohort 2). Except for one isolate of Cryptococcus gattii from a cohort 2 case, all other isolates were identified as Cryptococcus neoformans var. grubii, sex type α, genotype VNI, including Cryptococcus reisolated from the relapse or in the refractory state. No differences were observed with respect to Cryptococcus capsule size and in the melanin and phospholipase production. The cohort 1 patients presented higher prevalence of cryptococcemia, cerebral dissemination, chronic liver disease, and leucopenia, and have increased death rate. Apparently, the refractory and/or relapsing cryptococcosis in the AIDS patients were more related to the host and the extent of the infection than to the fungal characteristics. © The American Society of Tropical Medicine and Hygiene.

Current Features of Secondary (Acquired) Types of Immune Deficiency.

Secondary (acquired) types of immune deficiencies (SID) take a leading place in practice of modern clinical immunology. The causes for SID development are extremely variable. Special attention is concerned with accumulating facts about target action of microorganisms, and first of all viruses, on certain processes in immune system. Damageable action of HIV-1 on cell elements expressing CD4 molecules is known in most precise manner. It is noteworthy that the search of real molecular defects, induced by microorganisms in immune system is required. It is not to be ruled out that the increased level of apoptosis of immune system cells is one of the causes of SID. The basis of it is disbalance between positive and negative activation processes of immunocompetent cells. Multiple factors may serve as apoptogens, including drugs (glucocorticoids etc.), xenobiotics, physical factors (radiation) and many others. In practice of clinical laboratories a certain spectrum of immunological investigations is recommended that allows to diagnose the degree of immunopathology. At present, in clinical practice these methods are focused around flow cytometry (immunophenotyping), immunodiffusion and immunoenzyme tests (determination of immunoglobulins, cytokines, other soluble components of immune system), tests of estimation of immunocompetent cell activation, proliferation and differentiation. As a prospective, some methods, based on identification of molecular defects in cells and soluble factors of immune system, may be taken into consideration.

Henan Province in China has a major epidemic of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS). Chinese medicine (CM) has been used throughout the last decade, and a management modality was developed, which can be described by unified-planning, graded-administration, and centralized-controlling (UGC). The UGC modality has one primary concept (patient-centered medicine from CM theory), four basic foundations (classifying administrative region, characteristics of CM on disease treatment, health resource conditions, and distribution of patients living with HIV), six important relationships (the "three uniformities and three combinations," and the six relationships therein guide the treatment of AIDS with CM), and four key sections (management, operation, records, and evaluation). In this article, the authors introduce the UGC modality, which could be beneficial to developing countries or resource-limited areas for the management of chronic infectious disease.

The in vitro effects of isoprinosine (ISO) on interleukin-2 (IL-2) production, the expression of Tac antigen (IL-2 receptor) on lymphocytes, and the ability of Leu 3(+) cells to absorb interleukin-1 (IL-1) were investigated in 10 patients with acquired immune deficiency syndrome (AIDS). In 9 of the 10 patients, production of IL-2 from mononuclear cells and Leu 3(+) cells was depressed; expression of Tac antigen on mononuclear cells and Leu 2(+) cells was found to be depressed in 9 of 10 patients. The ability of the Leu 3(+) lymphocytes to absorb IL-1 was depressed in all (four of four) patients studied. After ISO treatment, IL-2 production, Tac antigen expression and IL-1 absorption were restored to normal or near normal levels in most of the patients. These results suggest that ISO has an immunostimulating capacity in AIDS patients and that the potential of ISO in immune response restoration in AIDS patients deserves critical consideration.

A pilot project, ¿Youth Inform¿ endorsed by the Ministry of Health and Ministry of Education, Singapore, was undertaken in 1992 for 2 years. It aims to enhance sexually transmitted disease (STDs)/human immunodeficiency virus (HIV) control in Singapore by providing structured information for young people between the ages of 16 to 20 years in Polytechnics, Junior Colleges, Centralised Institutes and Pre-University Centres. Project Youth Inform comprises 8 components. They include a focus group discussion, a training seminar for teachers, a lecture/slide presentation cum question-and-answer session, an educational booklet/bookmark, exhibitions, a video, provisions for anonymous questions, and an evaluation. The programme is conducted during school hours at the premises of the institutions and the attendance per session is between 150 to 350 students. A total of 152 sessions have been completed for all the schools. It is ongoing and is currently administered by the School Health Service and Training and Health Education Department. Feedback from principals, teachers and students was gathered formally through surveys and informally through interviews and observations. One thousand students were randomly selected for the survey to assess their responses towards the programme. Eighty-six percent reported that they found it educational and informative. Indicators found to have an influence on the effectiveness of the programme were timing, vocabulary used (medical terms) and integration of the programme into the school's curriculum. In conclusion, Project Youth Inform was on the whole positively received. However, it is essential to constantly accommodate and adapt to new facts and methods of teaching and maintain close coordination with the Ministries and the schools. An effective STD/acquired immune deficiency syndrome programme is an important step towards the prevention, management and control of the epidemic.

South Africa is known to have one of the highest prevalence rates of human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) globally, with one in seven healthcare workers being HIV-positive. An HIV-positive healthcare workforce is less equipped to respond to the increasing spread of the epidemic. Assessment of the factors contributing to high HIV prevalence rates among healthcare workers is important in planning the development of human resources. This review sought to identify and understand predominant risky sexual behaviours among healthcare workers in HIV and AIDS-affected countries. This study reviewed articles focusing on sexual behaviour among healthcare workers. Major health science databases (e.g. ProQuest, Cochrane, PubMed and CINAHL) were searched for combinations of keywords including 'healthcare workers', 'risky sexual behaviour' and 'HIV and AIDS'. Articles from a range of countries met inclusion and exclusion criteria. Findings of the study revealed three main contributing factors: unprotected sex, multiple sex partners and sexual violence. Sexual violence emerged as the dominant risk factor in the majority of the studies. Most research was conducted in developed countries where the HIV infection rate is much lower than it is in developing countries. More research needs to be conducted in developing countries and appropriate strategies should be implemented to reduce sexual violence among healthcare workers. Appropriate procedures on reporting sexual violence coupled with education on HIV and AIDS as well as influencing attitudes and belief systems could assist in reducing the spread of HIV and AIDS within the healthcare workforce while minimising the effect on patient care.

Histoplasmosis is one of the most common and deadly opportunistic infections among persons living with human immunodeficiency virus (HIV)/acquired immune deficiency syndrome in Latin America, but due to limited diagnostic capacity in this region, few data on the burden and clinical characteristics of this disease exist. Between 2005 and 2009, we enrolled patients ≥ 18 years of age with suspected histoplasmosis at a hospital-based HIV clinic in Guatemala City. A case of suspected histoplasmosis was defined as a person presenting with at least three of five clinical or radiologic criteria. A confirmed case of histoplasmosis was defined as a person with a positive culture or urine antigen test for Histoplasma capsulatum . Demographic and clinical data were also collected and analyzed. Of 263 enrolled as suspected cases of histoplasmosis, 101 (38.4%) were confirmed cases. Median time to diagnosis was 15 days after presentation (interquartile range [IQR] = 5-23). Crude overall mortality was 43.6%; median survival time was 19 days (IQR = 4-69). Mycobacterial infection was diagnosed in 70 (26.6%) cases; 26 (25.7%) histoplasmosis cases were coinfected with mycobacteria. High mortality and short survival time after initial symptoms were observed in patients with histoplasmosis. Mycobacterial coinfection diagnoses were frequent, highlighting the importance of pursuing diagnoses for both diseases.

To determine if vesicular rosettes (VR), tubuloreticular structures (TRS), and "test-tube and ring-shaped forms" (TRF) are characteristic ultrastructural features of the syndromes of acquired immune deficiency (AIDS) or of unexplained persistent lymphadenopathy (PLS), the authors studied lymph nodes from nine patients with PLS, two patients with AIDS, and seven controls by electron microscopy. An average of 122 lymphocytes per case were photographed. VR were present in only 0.37% of lymphocytes in 4 of 11 index cases and were mimicked by grouped vesicles and degenerating multivesicular bodies (MVB). TRS were found in 10 of 11 index cases, compared with only one of seven controls (P less than 0.01). In the index cases, they were more frequent in AIDS (mean 21%) than in PLS lymphocytes (mean 4%) (P less than 0.05). MVB were found in all index cases and five of seven controls and were more frequent in index lymphocytes (mean 19%) than in controls (mean 5%) (P less than 0.01). TRF were found in one Haitian male with AIDS, where they were present in 4% of lymphocytes. VR are infrequent and indistinct. MVB probably reflect the reactivity of the lymphocytes. TRF is not a feature of PLS. The authors conclude that there are no pathognomonic ultrastructural markers of AIDS or PLS but that TRS are characteristic of both syndromes and occur frequently enough to be supportive to the diagnosis of AIDS and PLS.

Innate or acquired immune deficiency may show respiratory manifestations, often characterized by small airway involvement. The purpose of this article is to provide an overview of small airway disease across the major causes of immune deficiency. In patients with common variable immune deficiency, recurrent lower airway infections may lead to bronchiolitis and bronchiectasis. Follicular and/or granulomatous bronchiolitis of unknown origin may also occur. Bronchiolitis obliterans is the leading cause of death after the first year in patients with lung transplantation. Bronchiolitis obliterans also occurs in patients with allogeneic haematopoietic stem cell transplantation, especially in the context of systemic graft-versus-host disease. Small airway diseases have different clinical expression and pathophysiology across various causes of immune deficiency. A better understanding of small airways disease pathogenesis in these settings may lead to the development of novel targeted therapies. Copyright © 2015 SPLF. Published by Elsevier Masson SAS.

According to the 15 autopsies performed at the Department of Pathological Anatomy, Escola Paulista de Medicina, São Paulo, Brazil, it was confirmed that acquired immunodeficiency syndrome (AIDS) occurs preferably in young homosexual males, who die in a short period of time of the disease, which leads to a consumptive state verified by cachexia of the cadavers. The most affected organs of this series were the lungs and encephalum, exactly the ones responsible for the immediate cause of death. In this series of autopsies there were 9 types of microorganisms represented by virus, bacteria, fungi, protozoans and two types of tumors, Kaposi's sarcoma and lymphoma of the central nervous system. From the microorganisms, the most frequent was the Cytomegalovirus and, from the tumors, Kaposi's sarcoma. The various types of microorganisms were frequently associated, principally in the central nervous and digestive systems. There was also association of microorganisms with tumors. Besides the lesions produced by microorganisms there were other associated alterations as brown atrophy of neuronia, which was related to the infiltration of cerebral lymphoma, and the lymphocytic depletion of lymphoid organs due to immunological exhaustion. Cellular reaction to microorganisms was practically none, principally with Pneumocystis carinii and Cryptococcus neoformans, the first one behaving as an inert mould in the pulmonary alveoli and the second proliferating freely in tissues. In two cases there was no granulomatous reaction to Mycobacterium tuberculosis. The primary lymphoma of the central nervous system should be interpreted as a microglioma, i.e., a reticulosarcoma of this system according to Hortega's school.

Recent reports indicate that patients infected with HIV are at increased risk for the development of thrombosis. Among other possibilities, an acquired deficiency of protein S (PS), one of the plasma's natural anticoagulants, might explain this tendency. PS deficiency can be classified in three types depending on the levels of total and free protein (antigenic assays) as well as anticoagulant activity (functional assay). Although the prevalence of inherited PS deficiency is not known because of its rarity, several conditions can lead to acquired forms of the disease. We report two AIDS patients with coexistent type III PS deficiency and thrombosis. Our first patient presented with bilateral chronic leg ulcers and a skin biopsy revealed dermal microthromboses. On laboratory evaluation he had PS deficiency and was started on anticoagulation, but was lost to follow-up. The second patient presented with hepatic vein thrombosis (Budd-Chiari syndrome) and was also PS deficient. On long-term anticoagulation, she experienced resolution of the thrombosis. Neither patient had prior personal or family history of venous thrombosis, nor acquired risk factors such as immobility, acute infection, recent surgery, or hormonal therapy. The literature contains a few reports of skin ulcers and Budd-Chiari syndrome associated with PS deficiency, although none in AIDS patients. While a larger number of studies describe an association between PS deficiency and HIV infection, the causal effect of this deficiency on the thrombophilic tendency in AIDS has not been established. We propose that awareness of the increased risk for thrombosis in HIV infection is important to the understanding of disease pathophysiology and management of these patients.

Acquired color vision deficiency occurs as the result of ocular, neurologic, or systemic disease. A wide array of conditions may affect color vision, ranging from diseases of the ocular media through to pathology of the visual cortex. Traditionally, acquired color vision deficiency is considered a separate entity from congenital color vision deficiency, although emerging clinical and molecular genetic data would suggest a degree of overlap. We review the pathophysiology of acquired color vision deficiency, the data on its prevalence, theories for the preponderance of acquired S-mechanism (or tritan) deficiency, and discuss tests of color vision. We also briefly review the types of color vision deficiencies encountered in ocular disease, with an emphasis placed on larger or more detailed clinical investigations. Copyright © 2016 Elsevier Inc.

To investigate the traditional Chinese Medicine (TCM) etiology and pathogenesis of acquired immune deficiency syndrome (AIDS) by 18-month observation of Chinese rhesus macaques infected with simian immunodeficiency virus (SIV) mac239. Thirty-five healthy Chinese rhesus macaques were divided into a model group (n = 30) and a control group (n = 5). The model was established by inoculating monkeys intravenously with SIVmac239. Changes in TCM symptoms after SIV infection within 18 months were then observed and recorded. Routine blood tests, SIV viral load, T-lymphocyte subsets, plasma triiodothyronine (T3), tetraiodothyronine (T4), adrenocorticotropic hormone (ACTH) and cortisol (Cor) were tested periodically during the experiment. During the acute infection period of SIV, model monkeys temporarily showed clinical symptoms such as diarrhea, dysphoria and slight weight loss. Decrease percentages of CD4+ T-lymphocytes were observed but levels of T3, T4, Cor, and ACTH were relatively unchanged. Monkeys in the model group during the early and middle periods of infection showed no obvious symptoms, except few monkeys exhibited transient diarrhea and reduced food intake. All variables at this stage showed normal fluctuations. In the middle period model group monkeys showed chronic and persistent diarrhea, weight loss, reduced food intake and low levels of T3 and Cor. In the late period, symptoms including emaciation, weight loss, listlessness, crouching in corners and low levels of T3 appeared. The results suggest that the rhesus monkey SIV/SAIDS model can be applied to research on TCM etiology and pathogenesis of AIDS. According to this model, the etiology of disease is the SIV virus. The pathogenesis manifests as the invasion of SIV virus, incubation of the virus, balance between virus and healthy "Qi", damage to spleen and kidney as the disease progressed, exhaustion of vitality and finally the failure of five zang and six fu organs.

Stigma and discrimination attached to human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) have been recognised as a major obstacle to HIV prevention, treatment, care and support throughout the world. Stigma and discrimination are more devastating when they occur in health care settings where it is least expected. To explore the factors attributable to stigma and discrimination of people living with HIV in two Ethiopian rural hospitals on what they thought of health care professionals (HCPs) attending to them. A qualitative exploratory approach was used. Data collection was by means of audio-taped interview and Tesch's content analysis approach was used. The sample size for this study was determined by saturation of data and consisted of 16 participants who were people living with HIV admitted as inpatients to the two selected hospitals in Amhara region of Ethiopia. Participants' views were grouped into: fear of contact, delay of services, substandard services, denial of care, impoliteness of health care providers, breach of confidentiality and poor patient follow-up for persons infected with HIV. The health care settings have been recognised as one of the contexts where HIV and AIDS-related stigmatisation and discrimination can occur. Hospital policies and institutional support should be tailored to embrace people living with HIV as the provision of institutional support is imperative in creating a good working environment and improving the commitment of HCPs so as to enable them to provide holistic care for people living with HIV and AIDS (PLWHA) without discrimination.

Good syndrome (GS) is defined as the association between thymoma and immune deficiency. It is often complicated by broncho-pulmonary bacterial infections and rhinosinusitis. This disease accounts for only 5% of all parathymic syndromes. These recurrent respiratory infections can cause bronchiectasis associated with Good syndrome. We report the case of a 52-year old woman hospitalized for non resolutive infectious pneumonitis. Chest CT scan showed bronchiectasis associated with thymoma confirmed by biopsy. The discovery of hypogammaglobulinemia allowed the diagnosis of Good syndrome.

Pi (Spleen)-deficiency syndrome in tumor microenvironment is the pivotal pathogenesis of colorectal cancer immune escape.

Cancer immunoediting consists of three sequential phases: elimination, equilibrium, and escape. For colorectal adenoma-carcinoma sequence, the adenoma dysplastic progression may represent an equilibrium phase and the cancer stage as escape phase. Immune system eliminates transformed enterocytes by destroying them at first, sculpts them at the same time and selects the variants subsequently that are no longer recognized and insensitive to immune effectors, and finally induces immunosuppressive state within the tumor microenvironment that facilitates immune escape and tumor outgrowth. Immunosuppression and inflammation are the two crucial features of Pi (Spleen)-deficiency. Classic quotations, immune evidence and clinical observations suggest that Spleen (but not other organs) deficiency is the key pathogenesis of colorectal cancer (CRC) microenvironment. Weakness of old age, immunosuppressive cytokines from chronic inflammation, tumor-derived immunosuppressive factors and surrendered immune cells-regulatory T cells, myeloid-derived suppressor cells and tumor associated macrophages (TAMs) constitutes CRC microenvironment of Pi-deficiency. Furthermore, excess in superficiality, such as phlegm stagnation, blood stasis and toxin accumulation are induced by chronic inflammation on the basis of asthenia in origin, an immunosuppressive state. Great masters of Chinese medicine emphasize that strengthen Pi is the chief therapeutic principle for CRC which receives good therapeutic effects. So, Pi-deficiency based syndrome is the pivotal pathogenesis of tumor microenvironment. The immunosuppressive microenvironment facilitates immune escape which play an important role in the transition from adenoma to adenocarcinoma. There are some signs that strengthen Pi based treatment has potential capacity to ameliorate tumor environment. It might be a novel starting point to explore the mechanism of strengthen Pi based therapy in the prevention and treatment of CRC through regulation of

Histoplasmosis is common among persons living with human immunodeficiency virus/acquired immune deficiency syndrome (PLWHA) in Latin America, but its diagnosis is difficult and often nonspecific. We conducted prospective screening for histoplasmosis among PLWHA with signs or symptoms suggesting progressive disseminated histoplasmosis (PDH) and hospitalized in Hospital La María in Medellín, Colombia. The study's aim was to obtain a clinical and laboratory profile of PLWHA with PDH. During 3 years (May 2008 to August 2011), we identified 89 PLWHA hospitalized with symptoms suggestive of PDH, of whom 45 (51%) had histoplasmosis. We observed tuberculosis (TB) coinfection in a large proportion of patients with PDH (35%), so all analyses were performed adjusting for this coinfection and, alternatively, excluding histoplasmosis patients with TB. Results showed that the patients with PDH were more likely to have Karnofsky score ≤ 30 (prevalence ratio [PR] = 1.98, 95% confidence interval [CI] = 0.97-4.06), liver compromised with hepatomegaly and/or splenomegaly (PR = 1.77, CI = 1.03-3.06) and elevation in serum of alanine aminotransferase and aspartate aminotransferase to values > 40 mU/mL (PR = 2.06, CI = 1.09-3.88 and PR = 1.53, CI = 0.99-2.35, respectively). Using multiple correspondence analyses, we identified in patients with PDH a profile characterized by the presence of constitutional symptoms, namely weight loss and Karnofsky classification ≤ 30, gastrointestinal manifestations with alteration of liver enzymes and hepatosplenomegaly and/or splenomegaly, skin lesions, and hematological alterations. Study of the profiles is no substitute for laboratory diagnostics, but identifying clinical and laboratory indicators of PLWHA with PDH should allow development of strategies for reducing the time to diagnosis and thus mortality caused by Histoplasma capsulatum. © The American Society of Tropical Medicine and Hygiene.

Results showed that the patients with PDH were more likely to have Karnofsky score ≤ 30 (prevalence ratio [PR] = 1.98, 95% confidence interval [CI] = 0.97–4.06), liver compromised with hepatomegaly and/or splenomegaly (PR = 1.77, CI = 1.03–3.06) and elevation in serum of alanine aminotransferase and aspartate aminotransferase to values > 40 mU/mL (PR = 2.06, CI = 1.09–3.88 and PR = 1.53, CI = 0.99–2.35, respectively). Using multiple correspondence analyses, we identified in patients with PDH a profile characterized by the presence of constitutional symptoms, namely weight loss and Karnofsky classification ≤ 30, gastrointestinal manifestations with alteration of liver enzymes and hepatosplenomegaly and/or splenomegaly, skin lesions, and hematological alterations. Study of the profiles is no substitute for laboratory diagnostics, but identifying clinical and laboratory indicators of PLWHA with PDH should allow development of strategies for reducing the time to diagnosis and thus mortality caused by Histoplasma capsulatum.

In last fifteen years remarkable success in the fight against human immunodeficiency virus (HIV) is achieved globally. The number of HIV infections has decreased and the number of people on antiretroviral therapy is increased. This all is possible by strong political commitments and heavy investments in the fight against HIV. Pakistan is among few Asian countries in which HIV cases are increasing year by year since 1990. There are 94000 cases of HIV in Pakistan and only 14000 are registered with government. The main source of HIV infection in Pakistan is the use of contaminated injection equipment among people who inject drugs (PWID). The overall prevalence of HIV among PWID in Pakistan is 27.2%. There are five cities in Pakistan in which HIV prevalence is above 40% in PWIDs. In June 2016, United Nations political declaration on acquired immune deficiency syndrome (AIDS) provided a global mandate to fast-track the AIDS response over the next five years to achieve the targets in Sustainable Development Goals. To achieve the targets in fast-track AIDS response, the global leaders showed strong commitments to invest $ 26 billion per year by 2020. Pakistan needs to speed up its HIV control program. There is a dire need to locate all HIV positive people and enroll them in the treatment program. Pakistan also needs to calculate exact number of people living with HIV, increase HIV treatment centers and increase HIV awareness. Recently, Global Fund invested handsome money in the fight against HIV. Let's hope the country will have effective HIV control strategy to achieve the HIV elimination target by 2030.

Oral health care of patients with human immunodeficiency virus (HIV)/acquired immune-deficiency syndrome (AIDS) is a growing area of concern. Information on HIV- and AIDS-related knowledge among dental students provides a crucial foundation for efforts aimed at developing an appropriate dental curriculum on HIV and AIDS. The purpose of this study was to assess the knowledge and attitude of Indian clinical dental students towards the treatment of patients with HIV/AIDS and perceived sources of information regarding HIV-related issues. Data were collected from clinical dental students (third year, fourth year and internship) from three dental institutions in Delhi National Capital Region (NCR). The questions assessed the knowledge and attitude towards treatment of patients with HIV and the perceived source of information related to HIV. The willingness to treat HIV-positive patients among dental students was 67.0%, and 74.20% were confident of treating a patient with HIV/AIDS. The potential problems in rendering treatment to these patients were effect on the attitude of other patients (49.90%) and staff fears (52.50%). The correct knowledge regarding the infection-control practice (barrier technique) was found among only 15.50% of respondents. The respondents had sufficient knowledge regarding the oral manifestations of HIV/AIDS. There was no correlation between the knowledge and attitude score, demonstrating a gap between knowledge and attitude among dental students regarding treatment of HIV-infected patients. Appropriate knowledge has to be delivered through the dental education curriculum, which can instil confidence in students about their ability to manage HIV-positive patients. © 2014 FDI World Dental Federation.

To compare acquired immune deficiency syndrome (AIDS) related knowledge, attitudes, behaviors and their influencing factors among college students in different years in Beijing, and to provide evidence for targeted health education among college students in future. College students were selected by the stratified cluster sampling method, and a questionnaire survey was conducted among college students in year 2006 and 2016 in Beijing. The sample sizes were 1 800 and 3 001 college students, respectively. The contents of the questionnaire included: socio-demographic characteristics, AIDS related knowledge, AIDS related attitude, sex intercourse and its related risk behaviors, condom use intension, and AIDS related health education. Compared with the year 2006, the average AIDS knowledge scores of college students in year 2016 dropped from 12.78±1.95 to 11.90±2.56 (t=12.91, P<0.05), and the correct answer rates of questions in the knowledge part were decreased, too. Except for belief on condom use, the college students were more negative on AIDS related attitude and self-efficacy in year 2016 than in year 2006. Among the students who had sex experience, the rates of commercial sex [17.65% (33/187) vs. 6.53% (16/245), χ 2 =13.003, P<0.001] and the rates of homo-sexual intercourse [15.43% (29/188) vs. 4.13% (10/242), χ 2 =16.356, P<0.001] were higher in year 2016 than in year 2006. The main way for the students seeking pornographic information was changed from books to internet (41.15%) in 2016 compared with the year 2016. In 2016, the influencing factors of intention on condom use were male (OR=0.713), self-efficacy of condom purchase (OR=0.876), never received sex education before college (OR=0.752), self-efficacy of condom use (OR=1.135), belief of condom use (OR=1.775), and attitude towards AIDS patients (OR=1.136).

Hypogammaglobulinemia factitia- Munchausen syndrome masquerading as common variable immune deficiency

PubMed Central

2013-01-01

Background We describe the first case of a patient with factitious disorder who closely simulated a primary immune deficiency disorder – Common Variable Immune Deficiency (CVID), by surreptitiously ingesting non-steroidal anti-inflammatory agents. Case description He was treated with several expensive and potentially dangerous drugs before the diagnosis was established through collateral information. In retrospect he did not meet the proposed new criteria for CVID. These criteria may prove useful in distinguishing cases of CVID from secondary hypogammaglobulinemia. Conclusion It is imperative clinicians recognise patients with factitious disorder at the earliest opportunity to prevent iatrogenic morbidity and mortality. PMID:24341706

Pneumonia is the leading cause of death after acute spinal cord injury and is associated with poor neurological outcome. In contrast to the current understanding, attributing enhanced infection susceptibility solely to the patient’s environment and motor dysfunction, we investigate whether a secondary functional neurogenic immune deficiency (spinal cord injury-induced immune deficiency syndrome, SCI-IDS) may account for the enhanced infection susceptibility. We applied a clinically relevant model of experimental induced pneumonia to investigate whether the systemic SCI-IDS is functional sufficient to cause pneumonia dependent on spinal cord injury lesion level and investigated whether findings are mirrored in a large prospective cohort study after human spinal cord injury. In a mouse model of inducible pneumonia, high thoracic lesions that interrupt sympathetic innervation to major immune organs, but not low thoracic lesions, significantly increased bacterial load in lungs. The ability to clear the bacterial load from the lung remained preserved in sham animals. Propagated immune susceptibility depended on injury of central pre-ganglionic but not peripheral postganglionic sympathetic innervation to the spleen. Thoracic spinal cord injury level was confirmed as an independent increased risk factor of pneumonia in patients after motor complete spinal cord injury (odds ratio = 1.35, P < 0.001) independently from mechanical ventilation and preserved sensory function by multiple regression analysis. We present evidence that spinal cord injury directly causes increased risk for bacterial infection in mice as well as in patients. Besides obvious motor and sensory paralysis, spinal cord injury also induces a functional SCI-IDS (‘immune paralysis’), sufficient to propagate clinically relevant infection in an injury level dependent manner.

Acquired bone marrow failure syndromes encompass a unique set of disorders characterized by a reduction in the effective production of mature cells by the bone marrow (BM). In the majority of cases, these syndromes are the result of the immune-mediated destruction of hematopoietic stem cells or their progenitors at various stages of differentiation. Microbial infection has also been associated with hematopoietic stem cell injury and may lead to associated transient or persistent BM failure, and recent evidence has highlighted the potential impact of commensal microbes and their metabolites on hematopoiesis. We summarize the interactions between microorganisms and the host immune system and emphasize how they may impact the development of acquired BM failure.

Little is known about secondary impairments and overuse problems in patient with acquired or congenital upper limb deficiency. Our aim was to estimate the frequency of overuse problems in persons after unilateral upper limb deficiency and identify the factors relevant for development of these problems. Cross-sectional study conducted at the University Rehabilitation Institute in Ljubljana. In total, 65 persons after unilateral upper limb deficiency who had visited our subspecialist outpatient clinic during the 2011-2013 period (excluding those with other possible medical causes of overuse-type problems) were interviewed about the frequency, duration and severity of neck, elbow and shoulder pain and the presence of carpal tunnel syndrome and filled in the Orthotics and Prosthetics User Survey-Upper Extremity Functional Status questionnaire. The most frequent problem was carpal tunnel syndrome, followed by shoulder pain, neck pain and elbow pain. No statistically significant association of deficiency level, cause of deficiency, time since deficiency, extent of daily prosthesis use or type of prosthesis with frequency or severity of pain or number of problems was found. The presence of carpal tunnel syndrome decreased from wearing no prosthesis through aesthetic and body-powered to myoelectric prosthesis (p = 0.014). Factors contributing to overuse problems after upper limb deficiency are not straightforward, so a large multicentric study is warranted. Persons with acquired or congenital upper limb deficiency are under a heightened risk of developing overuse problems but the contributing factors are not clear, so regular individual follow-up is required. © The International Society for Prosthetics and Orthotics 2015.

Studies show that nearly 40 million people are living with human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) around the world and since the beginning of the epidemic, about 35 million have died from AIDS. Heterosexual intercourse is the most common route for transmission of HIV infection (85%). People with a sexually transmitted infection (STI), such as syphilis, genital herpes, chancroid, or bacterial vaginosis, are more likely to obtain HIV infection during sex. On the other hand, a patient with HIV can acquire other infections such as hepatitis C virus (HCV) and hepatitis B virus (HBV) and also STIs. Co-infections and co-morbidities can affect the treatment route of patients with HIV/AIDs. Sometimes, physicians should treat these infections before treating the HIV infection. Therefore, it is important to identify co-infection or comorbidity in patients with HIV/AIDS. This study was conducted in order to understand the prevalence of HIV/AIDS/STI co-infection. In this cross-sectional study, we evaluated all HIV/AIDS patients who were admitted to the infectious wards of Boo-Ali hospital (Southeastern Iran) between March 2000 and January 2015. All HIV/AIDS patients were studied for sexually transmitted infections (STI) such as syphilis, gonorrhea, hepatitis B virus (HBV) and genital herpes. A questionnaire including data on age, sex, job, history of vaccination against HBV, hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), hepatitis B surface antigen (anti-HBs), HCV-Ab, venereal disease research laboratory (VDRL) test, fluorescent treponemal antibody absorption (FTA-Abs) test, and urine culture was designed. Data was analyzed by the Chi square test and P values of < 0.05 were considered significant. Among the 41 patients with HIV/AIDS (11 females and 30 males; with age range of 18 to 69 years) five cases (12.1%) had a positive test (1:8 or more) for VDRL. The FTA-Abs was positive for all patients who

The Primary Immune Deficiency Treatment Consortium (PIDTC) is a collaboration of 41 North American centers studying therapy for rare primary immune deficiency diseases (PID) including Severe Combined Immune Deficiency (SCID), Wiskott-Aldrich syndrome (WAS) and chronic granulomatous disease (CGD). An additional 3 European centers have partnered with the PIDTC to study CGD. Natural history protocols of the PIDTC analyze outcomes of treatment for rare PID in multicenter longitudinal retrospective, prospective and cross-sectional studies. Since 2009, participating centers have enrolled over 800 subjects on PIDTC protocols for SCID, and enrollment on the studies in WAS and CGD is underway. Four pilot projects have been funded and 12 junior investigators have received fellowship awards. Important publications of the consortium describe outcomes of hematopoietic cell transplantation (HCT) for SCID during 2000–2009, diagnostic criteria for SCID, and the pilot project of newborn screening (NBS) for SCID in the Navajo Nation. The PIDTC Annual Scientific Workshops provide an opportunity to strengthen collaborations with junior investigators, patient advocacy groups and international colleagues. Funded by the NIAID and ORDR, NCATS, the PIDTC has recently received renewal for another 5 years. Here, we review accomplishments of the group, projects underway, highlights of recent workshops and challenges for the future. PMID:27262745

The human immunodeficiency virus and acquired immune-deficiency syndrome (HIV/AIDS) is still a 'family crises' which marks the beginning of the deterioration of the family unit and the trauma in the emotional, psychological and material lives of both the mother and child. In South African context where the majority of HIV-positive mothers are young single women who live in extended families, disclosure to the sexual partner alone is not an adequate condition for the success of prevention of mother to child transmission (PMTCT). In South Africa, close to one in three women who attend antenatal clinics are HIV positive. KwaZulu-Natal is one of the worst affected provinces, where as many as 40-60% of pregnant women attending antenatal services are living with HIV infection. The study sought to investigate the link between the home environment and its contribution to the success of the programme on PMTCT of HIV/AIDS. A qualitative, explorative, descriptive and contextual study was used in this study to explore whether the home environment for the support system is available for the HIV-positive women on the PMTCT programme. The population of this study included all women who have undergone counselling and tested HIV positive and who have joined the programme on PMTCT of HIV/AIDS in a specific hospital in KwaZulu-Natal Province. Although 14 women agreed to participate in the study, only 10 women were interviewed as saturation was attained. Data were collected using semi-structured interview schedule. Interviews were audio-taped and field notes were taken. Content analysis was used and it was done manually. This study revealed that one of the major issues still surrounding HIV/AIDS and PMTCT is that of non-disclosure, selective disclosure and the stigma and discrimination that surrounds this disease.

Objectives: Setarud (IMOD™) is a herbal medicine with beneficial effect for patients suffering Human immunodeficiency virus (HIV) infection and has been approved for IV (intra venues) injection. The beneficial effect of IMOD administration for acquired immune deficiency syndrome (AIDS) patient has been proved in previous clinical trials. Here the in vitro inhibitory effect of IMOD against HIV-1, Herpes simplex virus (HSV) and murine leukemia viruses (MLV) was evaluated. Materials and Methods: HIV single cycle replication and HSV plaque reduction assays were used to evaluate the anti-viral effect. The level of HIV replication was monitored by p24 capture Enzyme-linked immunosorbent assay (ELISA). The single round infection [with green fluorescent protein (GFP) reporter MLV and HIV], virucidal and time-of-additions (HSV) assays were utilized to determine the mode of anti-viral activity. The toxicity of IMOD for cells was monitored by XTT (sodium 3_-[1 (phenylaminocarbonyl)- 3,4-tetrazolium]-bis (4-methoxy-6-nitro)benzene sulfonic acid) cell proliferation assay kit. Results: IMOD inhibited 50% of HIV-1 and HSV replication (IC50) at 6.5 × 10-4 and 4.3 × 10-3V/V concentrations, respectively. The IC50 value against HIV-1 and MLV infection were 6 × 10-4V/V and 4.9 × 10-4V/V. Virucidal assay showed that IMOD reduces the potency of HIV and HSV particles to 41 and 54% of control, respectively. Time-of-addition study revealed that IMOD inhibits the replication of HSV at a stage after penetration of virions to the target cells. Conclusions: Data from this study indicate that IMOD has significant anti-viral activity against HIV, HSV and MLV. Setarud could be subjected to further investigation after isolation of the constituents and determination of the toxic components. PMID:23087503

To study the effects of AÇaí(Euterpe oleracea) on lipid metabolism, immune substances and endocrine hormone level in rats with deficiency-heat and deficiency-cold syndrome. SD rats were divided into blank control group, deficiency-heat model group, deficiency-heat & Phellodendri Cortex group, deficiency-heat & AÇaí high dose and low dose groups, deficiency-cold model group, deficiency-cold & Cinnamomi Cortex group, deficiency-cold & AÇaí high dose and low dose groups. The rats received intramuscular injection of dexamethasone sodium phosphate (0.35 mg) or hydrocortisone sodium succinate (20 mg) for 21 days to set up deficiency-heat models and deficiency-cold models. Then the changes in fatmetabolism levels (FFA, LPL, HL) and immune indexes (IgG, IgM, C3 and C4) were detected by colorimeter; and the levels of endocrine hormone indexes (CORT, E2 and T) were detected by radioimmunoassay. The levels of FFA, LPL and HL in serum were reduced (P<0.01 or P<0.001); levels of IgG, IgM and C3 in serum were increased (P<0.05 or P<0.001); level of CORT in serum was increased (P<0.05) and the level of E2, E2/T in serum were reduced in the AÇaí high dose group (P<0.05). The effect of high dose AÇaí on fat metabolism was not obvious in deficiency-cold models, but the levels of IgG, IgM, C3 and CORT in serum were increased (P<0.05 or P<0.001). AÇaí was showed the same effect trend with Phellodendri Cortex in adjusting the levels of deficiency-heat rats; but unlike Cinnamomi Cortex, AÇaí was showed no obvious effect in adjusting the levels of deficiency-cold rats. In this experiment, homogeneous comparison and heterogeneous disproof were used to verify the cold nature of Çaí. Copyright© by the Chinese Pharmaceutical Association.

Systemic lupus erythematosus (SLE) is a systemic inflammatory disease of connective tissue with an unknown etiology and a rich clinical picture with involvement of multiple organs. Given the rich symptomatology, application of the current classification criteria is associated with a significant risk of attributing symptoms of other pathologies to lupus and/or other connective tissue disease. Inherited and acquired immune deficiencies may sometimes demonstrate a lupus-like clinical symptomatology. In this work we reviewed 4 of cases referred to the Department of Internal Diseases and Rheumatology of the Silesian Medical University in Katowice with suspected or confirmed systemic lupus erythematosus. A positive anti-HIV antibody test led to the diagnosis of the acquired immunodeficiency syndrome (AIDS). Due to the close similarity of the clinical picture and the presence of antinuclear antibodies in both diseases, the authors postulate that the anti-HIV antibody test should be done routinely in patients with connective tissue diseases.

Isolated acquired factor VII (FVII) deficiency is a rare haemorrhagic disorder. We report what is currently known about the pathogenesis, clinical features, diagnosis, treatment and prognosis of acquired FVII deficiency. We performed a literature search and included all articles published between 1980 and August 2015. Acquired FVII deficiency has been reported in 42 patients. There are well-established clinical diseases associated with acquired FVII deficiency, most notably infections, malignancy and haematological stem cell transplantation. The exact pathogenesis of the diseases is still unknown, but different pathophysiological hypotheses have been suggested. The clinical manifestation of acquired FVII deficiency varies greatly in severity; asymptomatic course as well as severe life-threatening bleeding diathesis and fatal bleedings have been described.

Acquired Amino Acid Deficiencies: A Focus on Arginine and Glutamine.

Nonessential amino acids are synthesized de novo and therefore not diet dependent. In contrast, essential amino acids must be obtained through nutrition since they cannot be synthesized internally. Several nonessential amino acids may become essential under conditions of stress and catabolic states when the capacity of endogenous amino acid synthesis is exceeded. Arginine and glutamine are 2 such conditionally essential amino acids and are the focus of this review. Low arginine bioavailability plays a pivotal role in the pathogenesis of a growing number of varied diseases, including sickle cell disease, thalassemia, malaria, acute asthma, cystic fibrosis, pulmonary hypertension, cardiovascular disease, certain cancers, and trauma, among others. Catabolism of arginine by arginase enzymes is the most common cause of an acquired arginine deficiency syndrome, frequently contributing to endothelial dysfunction and/or T-cell dysfunction, depending on the clinical scenario and disease state. Glutamine, an arginine precursor, is one of the most abundant amino acids in the body and, like arginine, becomes deficient in several conditions of stress, including critical illness, trauma, infection, cancer, and gastrointestinal disorders. At-risk populations are discussed together with therapeutic options that target these specific acquired amino acid deficiencies.

In vivo treatment with interleukin 12 protects mice from immune abnormalities observed during murine acquired immunodeficiency syndrome (MAIDS)

PubMed Central

1994-01-01

Lymphoproliferation, chronic B cell activation resulting in hypergammaglobulinemia, and profound immunodeficiency are prominent features of a retrovirus-induced syndrome designated murine acquired immunodeficiency syndrome (MAIDS). In vivo treatment of infected mice with recombinant interleukin 12 (IL-12) beginning at the time of infection or up to 9 wk after virus inoculation markedly inhibited the development of splenomegaly and lymphadenopathy, as well as B cell activation and Ig secretion. Treatment with IL-12 also had major effects in preventing induction of several immune defects including impaired production of interferon gamma (IFN-gamma) and IL-2 and depressed proliferative responses to various stimuli. The therapeutic effects of IL-12 on the immune system of mice with MAIDS were also associated with reduced expression of the retrovirus that causes this disease (BM5def), with lesser effects on expression of ecotropic MuLV. IL-12 treatment was not effective in IFN-gamma knockout mice or in infected mice treated simultaneously with IL-12 and anti-IFN-gamma. These results demonstrate that induction and progression of MAIDS are antagonized by IL-12 through high-level expression of IFN-gamma and may provide an experimental basis for developing treatments of retrovirus- induced immune disorders with similar immunopathogenic mechanisms.

Lynch syndrome is a cancer predisposition syndrome caused by germline mutations in mismatch repair (MMR) genes. MMR deficiency is a ubiquitous feature of Lynch syndrome-associated colorectal adenocarcinomas; however, it remains unclear when the MMR-deficient phenotype is acquired during tumorigenesis. To probe this issue, the present study examined genetic alterations and MMR statuses in Lynch syndrome-associated colorectal adenomas and adenocarcinomas, in comparison with sporadic adenomas. Among the Lynch syndrome-associated colorectal tumors, 68 of 86 adenomas (79%) and all adenocarcinomas were MMR-deficient, whereas all the sporadic adenomas were MMR-proficient, as determined by microsatellite instability testing and immunohistochemistry for MMR proteins. Sequencing analyses identified APC or CTNNB1 mutations in the majority of sporadic adenomas (58/84, 69%) and MMR-proficient Lynch syndrome-associated adenomas (13/18, 72%). However, MMR-deficient Lynch syndrome-associated adenomas had less APC or CTNNB1 mutations (25/68, 37%) and frequent frameshift RNF43 mutations involving mononucleotide repeats (45/68, 66%). Furthermore, frameshift mutations affecting repeat sequences constituted 14 of 26 APC mutations (54%) in MMR-deficient adenomas whereas these frameshift mutations were rare in MMR-proficient adenomas in patients with Lynch syndrome (1/12, 8%) and in sporadic adenomas (3/52, 6%). Lynch syndrome-associated adenocarcinomas exhibited mutation profiles similar to those of MMR-deficient adenomas. Considering that WNT pathway activation sufficiently drives colorectal adenoma formation, the distinct mutation profiles of WNT pathway genes in Lynch syndrome-associated adenomas suggest that MMR deficiency commonly precedes adenoma formation.

Background and Objectives: Human immunodeficiency virus (HIV) is a major public health challenge. Unjustified calls for the isolation of patients with HIV infection might further constrain the potential for expansion of clinical services to deal with a greater number of such patients. This infectious illness can evoke irrational emotions and fears in health care providers. Keeping this in view, a study was conducted to assess the knowledge and attitudes related to HIV/acquired immune deficiency syndrome (AIDS) among dental and medical students. Methodology: Descriptive cross-sectional survey of the entire dental and medical undergraduate students from two colleges was carried out using a pretested, self-administered questionnaire. Descriptive statistics such as percentage was used to present the data. Results: Ninety-eight percentage medical and dental undergraduate graduate students knew about HIV transmission in the hospital. Journals and internet were the leading source of information among both medical and dental undergraduates. The majority of respondents discussed HIV-related issues with their classmates. Surprisingly, 38% medical and 52% dental undergraduates think that HIV patient should be quarantined (isolation) to prevent the spread of infection. 68% medical and 60% dental undergraduates are willing to rendering dental/medical care to HIV-infected patients. Relatively large proportion (98%) of participants was willing to participate for HIV prevention program. Conclusion: The knowledge of medical and dental students is adequate, but the attitude needs improvement. Dental and medical students constitute a useful public health education resource. Comprehensive training, continuing education, and motivation will improve their knowledge and attitude, which enable them to provide better care to HIV patients. PMID:26538940

The Hayflick Limit and Age-Related Adaptive Immune Deficiency.

PubMed

Gill, Zoe; Nieuwoudt, Martin; Ndifon, Wilfred

2018-01-01

The adaptive immune system (AIS) acquires significant deficiency during chronological ageing, making older individuals more susceptible to infections and less responsive to vaccines compared to younger individuals. At the cellular level, one of the most striking features of this ageing-related immune deficiency is the dramatic loss of T-cell diversity that occurs in elderly humans. After the age of 70 years, there is a sharp decline in the diversity of naïve T cells, including a >10-fold decrease in the CD4+ compartment and a >100-fold decrease in the CD8+ compartment. Such changes are detrimental because the AIS relies on a diverse naïve T-cell pool to respond to novel pathogens. Recent work suggests that this collapse of naïve T-cell diversity results from T cells reaching the Hayflick limit and being eliminated through both antigen-dependent and -independent pathways. The progressive attrition of telomeres is the molecular mechanism that underlies this Hayflick limit. Therefore, we propose that by measuring the telomere lengths of T cells with high resolution, it is possible to develop a unique biomarker of immune deficiency, potentially much better correlated with individual susceptibility to diseases compared to chronological age alone. © 2017 S.

Sub-Saharan Africa bears an inordinate burden of human immunodeficiency virus (HIV) infection/acquired immune deficiency syndrome (AIDS). Reports have shown increased prevalence of clustering of cardiovascular risk factors referred to as metabolic syndrome in treatment-naïve patients and patients on highly active antiretroviral therapy (HAART). In view of the fact that metabolic syndrome is a heterogeneous disorder with substantial variability in the prevalence and component traits within and across populations and the dearth of publications on the prevalence and clinical correlates of metabolic syndrome in people living with HIV/AIDS (PLWHA) in Nigeria, this study was carried out to determine the prevalence and clinical correlates of metabolic syndrome among an HIV-infected outpatient population using the National Cholesterol Education Adult Treatment Panel III (NCEP ATP III), the International Diabetes Federation (IDF), and the Joint Interim Statement (JIS) definitions. We also sought to determine if HAART use and CD4 count level were associated with metabolic syndrome. This cross-sectional study involved 291 (95 men, 196 women) consecutive PLWHA. Anthropometry, blood pressure, fasting plasma glucose, and lipid profile values were determined. The prevalence rates of metabolic syndrome according to the ATP III, IDF, and JIS criteria were 12.7%, 17.2%, and 21.0%, respectively. Metabolic syndrome was significantly associated with female gender (all definitions), body mass index (all definitions), increasing age, and CD4 count (IDF definition). There was no significant association between metabolic syndrome and HAART. The concordance [kappa coefficient (κ)] between the definitions of metabolic syndrome varied between 0.583 and 0.878. The prevalence of metabolic syndrome varied with the criteria used and metabolic syndrome correlates with traditional cardiovascular risk factors rather than HAART-related factors.

concurrent toxoplasmosis infection of the brain, spinal cord, and muscle has never been reported together in a patient antemortem. Toxoplasma gondii is the most common focal central nervous system opportunistic infection in the acquired immune deficiency syndrome (AIDS) population. Despite this fact, isolated toxoplasmosis infection in the spinal cord is rarely reported. In addition, toxoplasmic myositis is also rarely diagnosed and Toxoplasma cysts are seldom found on biopsy. We present a patient with AIDS and toxoplasmosis resistant to standard anti-Toxoplasma therapy. a 34-year-old man with a history of untreated AIDS presented with symptoms of myelopathy. Pathologically proven toxoplasmosis of the spinal cord was diagnosed and no brain lesions were found. However, despite appropriate treatment and initiation of highly active antiretroviral therapy, the patient developed worsening symptoms, including myopathy and autonomic instability. Muscle biopsy revealed Toxoplasma cysts, and there was laboratory evidence of a restored immune system. we report the first case of toxoplasmosis presenting initially with myelitis in the absence of encephalitis that subsequently progressed to myositis despite antiparasitic treatment. We also discuss the possibility of immune reconstitution inflammatory syndrome as a cause of his deterioration.

To investigate the awareness of acquired immune deficiency syndrome (AIDS) knowledge and AIDS-related behaviors among youth students in gay dating sites, and to provide evidences for AIDS prevention education through the internet. The students in gay dating sites, selected by a snowball sampling, were interviewed by questionnaires. Chi-square tests were used to analyze the awareness of AIDS knowledge among the students of different characteristics. The Logistic regression was used to analyze the factors associated with ever testing for HIV. In the study, 469 youth students in gay dating sites filled in the questionnaires, and a total of 442 (94.2%) valid samples were collected. The awareness of HIV/AIDS knowledge for the public among the youth students in gay dating sites was 83.9% (371).The awareness of HIV/AIDS knowledge for the youth students was 77.1% (341), and the rate of ever testing for HIV was 52.0% (230). The awareness of HIV/AIDS knowledge for the public in the students were different in different age groups (P=0.001), different marital statuses (P<0.001), different sexual orientations (P<0.001), and different genders of the first sexual partner (P<0.001). The awareness of HIV/AIDS knowledge for the youth students were different in different age groups (P=0.010), different marital status (P=0.004), different sexual orientations (P<0.001), and different genders of the first sexual partner (P<0.001). The rate of ever having sexual intercourse among the youth students in gay dating sites was 75.1% (332), and the rate of multiple sexual partnerships among the youth students was 41.3% (137). Compared with homosexual orientation, sexual orientation as heterosexual (OR=0.282, 95%CI: 0.151 to 0.528) and not sure (OR=0.175, 95%CI: 0.035 to 0.885) were risk factors of ever testing for HIV. Multiple sexual partnerships (OR=2.103, 95%CI: 1.278 to 3.462) were promoting factors of ever testing for HIV. The rate of high-risk behaviors among the youth students in gay

Isolated acquired factor VII deficiency is a rare coagulopathy. It has been reported in 31 patients with malignancy, sepsis, postoperatively, aplastic anemia, and during bone marrow transplantation. We discuss, through a new case of acquired factor VII deficiency, the characteristics of this disease when it is associated with acute myeloid leukemia. Acquired factor VII deficiency in hematological diseases can be caused by intensive chemotherapy, infections, or hepatic dysfunction. The best treatment in developing countries remains corticosteroids associated with plasma exchange, frozen plasma, and antibiotics.

Genetic Associations in Acquired Immune-Mediated Bone Marrow Failure Syndromes: Insights in Aplastic Anemia and Chronic Idiopathic Neutropenia

Increasing interest on the field of autoimmune diseases has unveiled a plethora of genetic factors that predispose to these diseases. However, in immune-mediated bone marrow failure syndromes, such as acquired aplastic anemia and chronic idiopathic neutropenia, in which the pathophysiology results from a myelosuppressive bone marrow microenvironment mainly due to the presence of activated T lymphocytes, leading to the accelerated apoptotic death of the hematopoietic stem and progenitor cells, such genetic associations have been very limited. Various alleles and haplotypes of human leucocyte antigen (HLA) molecules have been implicated in the predisposition of developing the above diseases, as well as polymorphisms of inhibitory cytokines such as interferon-γ, tumor necrosis factor-α, and transforming growth factor-β1 along with polymorphisms on molecules of the immune system including the T-bet transcription factor and signal transducers and activators of transcription. In some cases, specific polymorphisms have been implicated in the outcome of treatment on those patients. PMID:22956967

Immune deficiency as a risk factor in Epstein-Barr virus-induced malignant diseases.

Epstein-Barr virus (EBV) is a ubiquitous DNA virus that normally infects silently, establishing lifelong latency. Substantial empirical observations support the view that immunodeficiency is permissive in EBV-induced lymphoproliferative diseases (LPD). Primary immune deficient patients such as those with X-linked lymphoproliferative disease and individuals with acquired immune deficiency secondary to immunosuppressive drugs for organ transplantation or individuals infected with human immunodeficiency virus are also at very high risk for lethal LPD. The importance of immunodeficiency and EBV in the development of head and neck carcinomas and uterine cervical carcinoma is less clear. Methods are available for detecting immunodeficiency and EBV genome and thus preventive strategies are being developed to preclude LPD from occurring. PMID:2176975

Once animals have experienced a helminthic infection, they often show stronger protective immunity against subsequent infections. Although helminthic infections are well known to elicit Th2-type immune responses, it remains ill-defined where and how acquired protection is executed. Here we show that skin-invading larvae of the intestinal helminth Nippostrongylus brasiliensis are surrounded by skin-infiltrating cells and are prevented from migrating out of infected skin during the second but not the first infection. B cell– or IgE receptor FcεRI–deficient mice showed impaired larval trapping in the skin. Selective ablation of basophils, but not mast cells, abolished the larval trapping, leading to increased worm burden in the lung and hence severe lung injury. Skin-infiltrating basophils produced IL-4 that in turn promoted the generation of M2-type macrophages, leading to the larval trapping in the skin through arginase-1 production. Basophils had no apparent contribution to worm expulsion from the intestine. This study thus reveals a novel mode of acquired antihelminth immunity, in which IgE-armed basophils mediate skin trapping of larvae, thereby limiting lung injury caused by larval migration.

Computer-assisted tomography (CT) with 2 mm axial sections and reconstructions was carried out in 31 children affected by GH deficiency (GHD): 18 with idiopathic complete isolated GHD, 3 with idiopathic partial isolated GHD, 2 with idiopathic panhypopituitarism, 4 with isolated acquired GHD and 4 with acquired panhypopituitarism. Density in the intrasellar area on CT corresponded to that of cerebrospinal fluid in 13/20 cases with idiopathic hypopituitarism and in 2/8 cases with acquired hypopituitarism. The overall incidence of primary empty sella syndrome (PESS) in the GH deficient patients studied was thus over 48%, while in children without endocrine dysfunction, it was only 5/213 (2.4%). It is concluded that PESS is more frequent in childhood than assumed until now and that it is frequently associated with GHD.

Trade-offs between acquired and innate immune defenses in humans

McDade, Thomas W.; Georgiev, Alexander V.; Kuzawa, Christopher W.

2016-01-01

Immune defenses provide resistance against infectious disease that is critical to survival. But immune defenses are costly, and limited resources allocated to immunity are not available for other physiological or developmental processes. We propose a framework for explaining variation in patterns of investment in two important subsystems of anti-pathogen defense: innate (non-specific) and acquired (specific) immunity. The developmental costs of acquired immunity are high, but the costs of maintenance and activation are relatively low. Innate immunity imposes lower upfront developmental costs, but higher operating costs. Innate defenses are mobilized quickly and are effective against novel pathogens. Acquired responses are less effective against novel exposures, but more effective against secondary exposures due to immunological memory. Based on their distinct profiles of costs and effectiveness, we propose that the balance of investment in innate versus acquired immunity is variable, and that this balance is optimized in response to local ecological conditions early in development. Nutritional abundance, high pathogen exposure and low signals of extrinsic mortality risk during sensitive periods of immune development should all favor relatively higher levels of investment in acquired immunity. Undernutrition, low pathogen exposure, and high mortality risk should favor innate immune defenses. The hypothesis provides a framework for organizing prior empirical research on the impact of developmental environments on innate and acquired immunity, and suggests promising directions for future research in human ecological immunology.

Specific antibody deficiency (SAD) is an immune deficiency which has been reported in adults and children with recurrent respiratory tract infections; however, the clinical features of SAD are not well described. This study evaluated formally the clinical syndrome of SAD, by comparing the clinical features of children with SAD and those of children with recurrent infection but normal immune function tests. SAD was defined as an adequate IgG antibody response to less than 50% of 12 pneumococcal serotypes tested following 23-valent unconjugated pneumococcal immunization. An adequate IgG antibody response was defined as a post-immunization titre of >or= 1.3 microg/ml or >or= four times the preimmunization value. Seventy-four children with recurrent infection were evaluated where immune deficiencies other than SAD had been excluded. Eleven (14.9%) of these children had SAD. Clinical features differed between the group with SAD and the group with normal antibody responses. A history of otitis media, particularly in association with chronic otorrhoea was associated with SAD [relative risk (RR) of SAD in those with chronic otorrhoea 4.64 (P = 0.02)]. SAD was associated with allergic disease, particularly allergic rhinitis [RR of SAD in those with allergic rhinitis 3.77 (P = 0.04)]. These two clinical associations of SAD were independent in this study [RR of chronic otorrhoea in those with allergic rhinitis 0.85 (P = 0.28)]. SAD was not an age-related phenomenon in this population. SAD has a distinct clinical phenotype, presenting as recurrent infection associated with chronic otorrhoea and/or allergic disease, and the condition should be sought in children with these features.

Wiskott-Aldrich syndrome (WAS) is an X-linked immunodeficiency characterized by eczema, infections, and susceptibility to autoimmunity and malignancies. Thrombocytopenia is a constant finding, but its pathogenesis remains elusive. To dissect the basis of the WAS platelet defect, we used a novel conditional mouse model (CoWas) lacking Wiskott-Aldrich syndrome protein (WASp) only in the megakaryocytic lineage in the presence of a normal immunologic environment, and in parallel we analyzed samples obtained from patients with WAS. Phenotypic and functional characterization of megakaryocytes and platelets in mutant CoWas mice and patients with WAS with and without autoantibodies was performed. Platelet antigen expression was examined through a protein expression profile and cluster proteomic interaction network. Platelet immunogenicity was tested by using ELISAs and B-cell and platelet cocultures. CoWas mice showed increased megakaryocyte numbers and normal thrombopoiesis in vitro, but WASp-deficient platelets had short lifespan and high expression of activation markers. Proteomic analysis identified signatures compatible with defects in cytoskeletal reorganization and metabolism yet surprisingly increased antigen-processing capabilities. In addition, WASp-deficient platelets expressed high levels of surface and soluble CD40 ligand and were capable of inducing B-cell activation in vitro. WASp-deficient platelets were highly immunostimulatory in mice and triggered the generation of antibodies specific for WASp-deficient platelets, even in the context of a normal immune system. Patients with WAS also showed platelet hyperactivation and increased plasma soluble CD40 ligand levels correlating with the presence of autoantibodies. Overall, these findings suggest that intrinsic defects in WASp-deficient platelets decrease their lifespan and dysregulate immune responses, corroborating the role of platelets as modulators of inflammation and immunity.

An Increased Risk of Osteoporosis during Acquired Immunodeficiency Syndrome

PubMed Central

2004-01-01

Osteoporosis is characterized by decreased bone mineral density and mechanistic imbalances of bone tissue that may result in reduced skeletal strength and an enhanced susceptibility to fractures. Osteoporosis in its most common form affects the elderly (both sexes) and all racial groups of human beings. Multiple environmental risk factors like acquired immune deficiency syndrome (AIDS) are believed to be one of the causes of osteoporosis. Recently a high incidence of osteoporosis has been observed in human immunodeficiency virus (HIV) infected individuals. The etiology of this occurrence in HIV infections is controversial. This problem seems to be more frequent in patients receiving potent antiretroviral therapy. In AIDS, the main suggested risk factors for the development of osteoporosis are use of protease inhibitors, longer duration of HIV infection, lower body weight before antiretroviral therapy, high viral load. Variations in serum parameters like osteocalcin, c-telopeptide, levels of elements like Calcium, Magnesium, Phosphorus, concentration of vitamin-D metabolites, lactate levels, bicarbonate concentrations, amount of alkaline phosphatase are demonstrated in the course of development of osteoporosis. OPG/RANKL/RANK system is final mediator of bone remodeling. Bone mineral density (BMD) test is of added value to assess the risk of osteoporosis in patients infected with AIDS. The biochemical markers also aid in this assessment. Clinical management mostly follows the lines of treatment of osteoporosis and osteopenia. PMID:15912194

This study aimed to determine whether the human immunodeficiency virus (HIV) exists in giant idiopathic esophageal ulcers in the patients with acquired immune deficiency syndrome (AIDS). 16 AIDS patients with a primary complaint of epigastric discomfort were examined by gastroscopy. Multiple and giant esophageal ulcers were biopsied and analyzed with pathology staining and reverse transcription-polymerase chain reaction (RT-PCR) to determine the potential pathogenic microorganisms, including HIV, cytomegalovirus (CMV) and herpes simplex viruses (HSV). HIV was detected in ulcer samples from 12 out of these 16 patients. Ulcers in 2 patients were infected with CMV and ulcers in another 2 patients were found HSV positive. No obvious cancerous pathological changes were found in these multiple giant esophageal ulcer specimens. HIV may be one of the major causative agents of multiple benign giant esophageal ulcers in AIDS patients.

2016-06-01

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.

Lack of recognition of human immunodeficiency virus (HIV) infection especially in children and delayed implementation of effective control programs makes HIV infection as a major cause for concern. Information on HIV epidemiology in Iran as well as other Islamic countries is limited. The aim of our study was to describe the clinical manifestation and laboratory finding of HIV infected children who were admitted to a referral Children Medical Center (CMC) in Tehran, Iran, during 11 years from January 2002 to January 2013. This was a retrospective study carried out over a period of 11 years. The records of all patients attending to the CMC with confirmed acquired immunodeficiency syndrome (AIDS) were screened. The patients were evaluated for social circumstance, family history, age, gender, clinical, and laboratory features. Clinical data including fever, respiratory distress, diarrhea, rash, etc. as well as laboratory tests including complete blood count, serum glucose level, electrolytes, liver function test, cultures, CD4 lymphocyte count were evaluated. During the study period, 32 HIV positive children were enrolled. The majority of patients were presented with weight loss, prolonged fever, respiratory infection and chronic diarrhea. In this study, salmonella infections as well as streptococcal pneumonia and candida infections followed by, tuberculosis and Pseudomonas aeruginosa infections were the predominant opportunistic infections. Since the number of HIV-positive children has been alarmingly increasing in recent years and perinatal transmission is the most common route of HIV infection in children, essential recommendations for prenatal HIV testing as well as appropriate antiretroviral therapy by HIV infected mothers are needed. © 2015 Wiley Periodicals, Inc.

A Tumor Profile in Primary Immune Deficiencies Challenges the Cancer Immune Surveillance Concept.

PubMed

Satgé, Daniel

2018-01-01

Under the concept of cancer immune surveillance, individuals with primary immune deficiencies would be expected to develop many more malignancies and show an excess of all types of cancers, compared to people with a normal immune system. A review of the nine most frequent and best-documented human conditions with primary immune deficiency reveals a 1.6- to 2.3-fold global increase of cancer in the largest epidemiological studies. However, the spectrum of cancer types with higher frequencies is narrow, limited mainly to lymphoma, digestive tract cancers, and virus-induced cancers. Increased lymphoma is also reported in animal models of immune deficiency. Overstimulation of leukocytes, chronic inflammation, and viruses explain this tumor profile. This raises the question of cancers being foreign organisms or tissues. Organisms, such as bacteria, viruses, and parasites as well as non-compatible grafts are seen as foreign (non-self) and identified and destroyed or rejected by the body (self). As cancer cells rarely show strong (and unique) surface antibodies, their recognition and elimination by the immune system is theoretically questionable, challenging the immune surveillance concept. In the neonatal period, the immune system is weak, but spontaneous regression and good outcomes occur for some cancers, suggesting that non-immune factors are effective in controlling cancer. The idea of cancer as a group of cells that must be destroyed and eliminated appears instead as a legacy of methods and paradigms in microbiological medicine. As an alternative approach, cancer cells could be considered part of the body and could be controlled by an embryonic and neonatal environment.

Five ARL patients underwent ¹⁸F-FDG PET/CT at Peking Union Medical College Hospital from October 2008 to January 2013. Two patients received two additional follow-up studies 6 months later. Among these 5 patients, ¹⁸FDG-PET/CT helped in diagnosis of two patient and changed therapeutic strategy in other two patients. In two patients underwent ¹⁸F-FDG PET/CT brain scans, low-metabolism lesion was newly found in cerebral cortex. Of 4 patients receiving highly active antiretroviral therapy, PET/CT also demonstrated diffusely elevated ¹⁸F-FDG uptake in subcutaneous adipose tissue in two patients. ¹⁸F-FDG PET/CT is a highly useful tool in the diagnosis and treatment of ARL patients, in particular in the identification of associated encephalopathy and lipodystrophy.

Most autosomal genetic causes of childhood-onset hypogammaglobulinemia are currently not well understood. Most affected individuals are simplex cases, but both autosomal-dominant and autosomal-recessive inheritance have been described. We performed genetic linkage analysis in consanguineous families affected by hypogammaglobulinemia. Four consanguineous families with childhood-onset humoral immune deficiency and features of autoimmunity shared genotype evidence for a linkage interval on chromosome 4q. Sequencing of positional candidate genes revealed that in each family, affected individuals had a distinct homozygous mutation in LRBA (lipopolysaccharide responsive beige-like anchor protein). All LRBA mutations segregated with the disease because homozygous individuals showed hypogammaglobulinemia and autoimmunity, whereas heterozygous individuals were healthy. These mutations were absent in healthy controls. Individuals with homozygous LRBA mutations had no LRBA, had disturbed B cell development, defective in vitro B cell activation, plasmablast formation, and immunoglobulin secretion, and had low proliferative responses. We conclude that mutations in LRBA cause an immune deficiency characterized by defects in B cell activation and autophagy and by susceptibility to apoptosis, all of which are associated with a clinical phenotype of hypogammaglobulinemia and autoimmunity.

This report concerns an immune deficiency disorder in a girl with eczema. She has had recurrent infections including three severe attacks of herpes simplex and five attacks of pneumococcal meningitis. There is a moderate lymphopenia, dysgammaglobulinaemia with high IgG, high IgA, and low IgM; lymphocyte transformation with phytohaemagglutinin is impaired. Production of circulating antibody is abnormal, as are delayed hypersensitivity reactions. Although there is no thrombocytopenia, the resemblance to the Wiskott-Aldrich syndrome is discussed.

Vitamin D deficiency and metabolic syndrome are 2 very common health problems in the Spanish population. It has been suggested that patients with metabolic syndrome may be vitamin D deficient more often than subjects without it and that low vitamin D levels may predispose to metabolic syndrome development. However, the results of prospective and intervention studies have been different and such relationship remains unclear. We assessed the relationship between 25-hydroxyvitamin D levels and the prevalence and incidence of metabolic syndrome. We undertook a population-based cohort study in Spain. At baseline (1996-1998), 1,226 subjects were evaluated. Follow-up visits were performed in 2002-2004 and 2005-2007.At baseline and follow-up, participants underwent an interview and a standardized clinical examination with an oral glucose tolerance test in those subjects without known diabetes. At the second visit, 25-hydroxyvitamin D levels and intact parathyroid hormone levels were measured. The prevalence of metabolic syndrome at the second and third visit was 29.4 and 42.5%, respectively. Mean levels of 25-hydroxyvitamin D were lower in subjects with metabolic syndrome: 21.7 (6.21) vs 23.35 (6.29) ng/ml, P<.001.The prevalence of vitamin D deficiency (25-hydroxyvitamin D<20 ng/ml) at the second evaluation was 34.7%, with significant differences between subjects with and without metabolic syndrome(34.6 vs 26.5%, P<.01). Men with vitamin D deficiency had more frequently hypertension and metabolic syndrome than men with normal levels. Women with vitamin D deficiency had more frequently hyperglycemia, hypertension, increased waist circumference and hypertriglyceridemia. In a prospective study, 25-hydroxyvitamin D values<20 ng/ml were not significantly associated with an increased risk of developing metabolic syndrome in the next 5 years (odds ratio 0,99, 95% confidence interval 0.57-1.7, P=.97) after adjusting by sex and age. Vitamin D deficiency is associated with an

Treatment of infectious complications of acquired immunodeficiency syndrome.

The infectious complications of the acquired immunodeficiency syndrome (AIDS) are discussed, and the conventional and nonconventional therapies used for these infections are reviewed. The infections most commonly encountered in patients with AIDS are Pneumocystis carinii pneumonia (58%), Candida esophagitis (31%), toxoplasmosis (21%), cytomegalovirus infections (15%), and herpes-simplex virus infections (12%). Pneumocystis carinii pneumonia is the most common life-threatening process in these patients. Trimethoprim-sulfamethoxazole (TMP-SMZ) is considered the drug of choice for its treatment. Oral candidiasis often indicates the progression to AIDS in the high-risk populations of homosexual or bisexual men, intravenous drug abusers, and individuals with hemophilia. Nystatin suspension is commonly used to treat oral candidiasis, while Candida esophagitis demands systemic therapy with ketoconazole. Toxoplasmosis most commonly manifests itself in patients with AIDS as a cerebral mass lesion. The recommended therapy includes sulfadiazine and pyrimethamine. AIDS patients frequently experience protozoal invasion of the intestinal tract with Giardia lamblia, Isospora belli, and Cryptosporidium muris. Various drugs have been tried for these infections, including quinacrine hydrochloride, metronidazole, TMP-SMZ, and spiramycin. Cytomegalovirus (CMV) infections commonly involve the lungs, gastrointestinal tract, eyes, brain, and nervous system. Attempts to treat these disseminated CMV infections with antiviral agents, including acyclovir, have not been successful. However, acyclovir has been found beneficial in the treatment of herpes-simplex virus infections. Multiple infectious complications may occur in patients with AIDS as a result of the cellular-immune deficiency associated with this disease. Until more research is done with AIDS patients, therapy must be based on the data available from the treatment of these infections in immunosuppressed patients without AIDS.

During an 8-year period of observation, defects of immune responses were characterized and monitored in 40 of 50 Polish children with Nijmegen breakage syndrome referred to the Children's Memorial Health Institute in Warsaw. The following parameters were determined at diagnosis: (1) concentrations of serum IgM, IgG, IgA; (2) concentrations of IgG subclasses; and (3) lymphocyte subpopulations. In addition, naturally acquired specific antibodies against Streptococcus pneumoniae were determined in 20 patients with a history of recurrent respiratory infections. During follow-up, total serum immunoglobulins and IgG subclasses were monitored systematically in 17 patients who did not receive immunomodulatory therapy. Moreover, anti-HBs antibody response was measured after vaccination of 20 children against HBV. We found that the immune deficiency in NBS is profound, highly variable, with a tendency to progress over time. Systematic monitoring of the humoral response, despite good clinical condition, is essential for early medical intervention. PMID:12390322

We report a 20-year-old man with gigantism syndrome, hypertrophic cardiomyopathy, muscle weakness, exercise intolerance, and severe psychomotor retardation since childhood. Histochemical and biochemical analysis of skeletal muscle biopsy revealed myoadenylate deaminase deficiency; molecular genetic analysis confirmed the diagnosis of primary (inherited) myoadenylate deaminase deficiency. Plasma, urine, and muscle carnitine concentrations were reduced. L-Carnitine treatment led to gradual improvement in exercise tolerance and cognitive performance; plasma and tissue carnitine levels returned to normal, and echocardiographic evidence of left ventricular hypertrophy disappeared. The combination of inherited myoadenylate deaminase deficiency, gigantism syndrome and carnitine deficiency has not previously been described.

Deficiency of adenosine deaminase (ADA, EC3.5.4.4), a housekeeping enzyme of purine metabolism encoded by the Ada gene, is a cause of human severe combined immune deficiency (SCID). Numerous deleterious mutations occurring in the ADA gene have been found in patients with profound lymphopenia (T - B - NK - ), thus underscoring the importance of functional purine metabolism for the development of the immune defense. While untreated ADA SCID is a fatal disorder, there are multiple life-saving therapeutic modalities to restore ADA activity and reconstitute protective immunity, including enzyme replacement therapy (ERT), allogeneic hematopoietic stem cell transplantation (HSCT) and gene therapy (GT) with autologous gene-corrected hematopoietic stem cells (HSC). We review the pathogenic mechanisms and clinical manifestations of ADA SCID.

Nutrition plays a major role in the management of both acute and chronic diseases, in terms of body’s response to the pathogenic organism. An array of nutrients like macro- and micro-nutrients, vitamins, etc., are associated with boosting the host’s immune responses against intracellular pathogens including mycobacterium tuberculosis (M.tb). These nutrients have an immunomodulatory effects in controlling the infection and inflammation process and nutritional deficiency of any form, i.e., malnutrition may lead to nutritionally acquired immunodeficiency syndrome, which greatly increases an individual’s susceptibility to progression of infection to disease. This narrative review looks at the various mechanisms by which nutrition or its deficiency leads to impaired cell mediated and humoral immune responses, which in turn affects the ability of an individual to fight M.tb infection or disease. There is very little evidence in the literature that any specific food on its own or a specific quantity can alter the course of TB disease or be effective in the treatment of malnutrition. Further clinical trials or studies will be needed to recommend and to better understand the link between malnutrition, tuberculosis, and impaired immunity. PMID:29093710

Heterotrimers composed of B cell CLL/lymphoma 10 (BCL10), mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1), and caspase recruitment domain–containing (CARD) family adaptors play a role in NF-κB activation and have been shown to be involved in both the innate and the adaptive arms of immunity in murine models. Moreover, individuals with inherited defects of MALT1, CARD9, and CARD11 present with immunological and clinical phenotypes. Here, we characterized a case of autosomal-recessive, complete BCL10 deficiency in a child with a broad immunodeficiency, including defects of both hematopoietic and nonhematopoietic immunity. The patient died at 3 years of age and was homozygous for a loss-of-expression, loss-of-function BCL10 mutation. The effect of BCL10 deficiency was dependent on the signaling pathway, and, for some pathways, the cell type affected. Despite the noted similarities to BCL10 deficiency in mice, including a deficient adaptive immune response, human BCL10 deficiency in this patient resulted in a number of specific features within cell populations. Treatment of the patient’s myeloid cells with a variety of pathogen-associated molecular pattern molecules (PAMPs) elicited a normal response; however, NF-κB–mediated fibroblast functions were dramatically impaired. The results of this study indicate that inherited BCL10 deficiency should be considered in patients with combined immunodeficiency with B cell, T cell, and fibroblast defects. PMID:25365219

Monoallelic germline mutations in one of the DNA mismatch repair (MMR) genes cause Lynch syndrome, with a high lifetime risks of colorectal and endometrial cancer at adult age. Less well known, is the constitutional mismatch repair deficiency (CMMRD) syndrome caused by biallelic germline mutations in MMR genes. This syndrome is characterized by the development of childhood cancer. Patients with CMMRD are at extremely high risk of developing multiple cancers including hematological, brain and intestinal tumors. Mutations in MMR genes impair DNA repair and therefore most tumors of patients with CMMRD are hypermutated. These mutations lead to changes in the translational reading frame, which consequently result in neoantigen formation. Neoantigens are recognized as foreign by the immune system and can induce specific immune responses. The growing evidence on the clinical efficacy of immunotherapies, such as immune checkpoint inhibitors, offers the prospect for treatment of patients with CMMRD. Combining neoantigen-based vaccination strategies and immune checkpoint inhibitors could be an effective way to conquer CMMRD-related tumors. Neoantigen-based vaccines might also be a preventive treatment option in healthy biallelic MMR mutation carriers. Future studies need to reveal the safety and efficacy of immunotherapies for patients with CMMRD. Copyright © 2017 The Author(s). Published by Elsevier B.V. All rights reserved.

Background Identifying genetic syndromes that lead to significant atopic disease can open new pathways for investigation and intervention in allergy. Objective To define a genetic syndrome of severe atopy, elevated serum IgE, immune deficiency, autoimmunity, and motor and neurocognitive impairment. Methods Eight patients from two families who had similar syndromic features were studied. Thorough clinical evaluations, including brain MRI and sensory evoked potentials, were performed. Peripheral lymphocyte flow cytometry, antibody responses, and T cell cytokine production were measured. Whole exome sequencing was performed to identify disease-causing mutations. Immunoblotting, qRT-PCR, enzymatic assays, nucleotide sugar and sugar phosphate analyses along with MALDI-TOF mass spectrometry of glycans were used to determine the molecular consequences of the mutations. Results Marked atopy and autoimmunity were associated with increased TH2 and TH17 cytokine production by CD4+ T cells. Bacterial and viral infection susceptibility were noted along with T cell lymphopenia, particularly of CD8+ T cells, and reduced memory B cells. Apparent brain hypomyelination resulted in markedly delayed evoked potentials and likely contributed to neurological abnormalities. Disease segregated with novel autosomal recessive mutations in a single gene, phosphoglucomutase 3 (PGM3). Although PGM3 protein expression was variably diminished, impaired function was demonstrated by decreased enzyme activity and reduced UDP-GlcNAc, along with decreased O- and N-linked protein glycosylation in patients’ cells. These results define a new Congenital Disorder of Glycosylation. Conclusions Autosomal recessive, hypomorphic PGM3 mutations underlie a disorder of severe atopy, immune deficiency, autoimmunity, intellectual disability and hypomyelination. PMID:24589341

Although prior studies suggest reduced androgen levels in women with acquired immune deficiency syndrome wasting, little is known regarding the regulation of adrenal and ovarian androgen secretion in such patients. We investigated ovarian and adrenal function in 13 human immunodeficiency virus-infected women with acquired immune deficiency syndrome wasting and 21 age- and body mass index-matched healthy control subjects studied in the early follicular phase. Subjects received hCG (5000 U, im) on d 1 and Cosyntropin (0.25 mg, i.v.) on d 3 after dexamethasone (1 mg, orally, at 2400 h) pretreatment on d 2. At baseline, human immunodeficiency virus-infected subjects demonstrated significantly reduced T [18 +/- 2 vs. 25 +/- 2 ng/dl (0.6 +/- 0.1 vs. 0.9 +/- 0.1 nmol/liter); P = 0.02], free T [1.5 +/- 0.1 vs. 2.4 +/- 0.2 pg/ml (5.3 +/- 0.5 vs. 8.3 +/- 0.6 pmol/liter); P = 0.001], androstenedione [119 +/- 6 vs. 162 +/- 14 ng/dl (4.16 +/- 0.20 vs. 5.66 +/- 0.48 nmol/liter); P = 0.02], and dehydroepiandrosterone sulfate [0.96 +/- 0.17 vs. 1.55 +/- 0.19 microg/ml (2.6 +/- 0.5 vs. 4.2 +/- 0.5 micromol/liter); P = 0.047] levels compared with the control subjects. T [8 +/- 2 vs. 6 +/- 2 ng/dl (0.3 +/- 0.1 vs. 0.2 +/- 0.1 nmol/liter); P = 0.48], free T [0.5 +/- 0.2 vs. 0.4 +/- 0.1 pg/ml (1.7 +/- 0.7 vs. 1.5 +/- 0.5 pmol/liter); P = 0.85], 17 hydroxyprogesterone [0.5 +/- 0.2 vs. 0.7 +/- 0.2 microg/liter (1.6 +/- 0.6 vs. 2.0 +/- 0.6 nmol/liter); P = 0.63], and androstenedione [-1 +/- 12 vs. 8 +/- 11 ng/dl (-0.03 +/- 0.42 vs. 0.28 +/- 0.39 nmol/liter), P = 0.61] responses to hCG were not different between the groups. Cortisol responses were increased and dehydroepiandrosterone sulfate responses were decreased in the human immunodeficiency virus-infected vs. control subjects after ACTH stimulation. The ratio of DHEA to cortisol was significantly decreased at 60 (71 +/- 11 vs. 107 +/- 10; P = 0.02) and 90 (63 +/- 8 vs. 102 +/- 9; P = 0.004) min post-ACTH in the human immunodeficiency

Even in cases where viral replication has been controlled by antiretroviral therapy for long periods of time, human immunodeficiency virus (HIV)-infected patients have several non-acquired immunodeficiency syndrome (AIDS) related co-morbidities, including liver disease, cardiovascular disease and neurocognitive decline, which have a clear impact on survival. It has been considered that persistent innate and acquired immune activation contributes to the pathogenesis of these non-AIDS related diseases. Immune activation has been related with several conditions, remarkably with the bacterial translocation related with the intestinal barrier damage by the HIV or by hepatitis C virus (HCV)-related liver cirrhosis. Consequently, increased morbidity and mortality must be expected in HIV-HCV coinfected patients. Disrupted gut barrier lead to an increased passage of microbial products and to an activation of the mucosal immune system and secretion of inflammatory mediators, which in turn might increase barrier dysfunction. In the present review, the intestinal barrier structure, measures of intestinal barrier dysfunction and the modifications of them in HIV monoinfection and in HIV-HCV coinfection will be considered. Both pathogenesis and the consequences for the progression of liver disease secondary to gut microbial fragment leakage and immune activation will be assessed.

Hemophagocytic lymphohistiocytosis (HLH) is a rare and aggressive disease involving immune system over-activation leading to hemophagocytosis. HLH requires early diagnosis and prompt treatment initiation, especially in patients with Acquired Immunodeficiency Syndrome (AIDS). We present a case of a middle-aged male with AIDS and renal failure, who developed HLH secondary to disseminated histoplasmosis. Etoposide chemotherapy as recommended by the HLH 2004 Guidelines was deferred and treatment focused instead on anti-fungal therapy. Anti-retroviral therapy followed thereafter.

Norovirus is an emerging pathogen causing gastroenteritis. We sought to identify factors associated with clinical outcomes in a cohort of patients with laboratory-confirmed norovirus infection. We performed a retrospective chart review of patients with positive norovirus polymerase chain reaction in stool between October 1, 2015, and May 31, 2016. 128 unique patients were identified during the study period, 64 of whom had immune deficiency, of which only 3 patients had a primary immune deficiency (common variable immune deficiency), while 61 patients had a secondary immune deficiency. 50% of patients with immune deficiency were hospitalized as compared to only 30% of the non-immune-deficient cohort (odds ratio: 2.1 (1.1-4.18, P=0.04). One-third (32.8%) of the patients had a polymicrobial stool infection, and 21.1% had concurrent Clostridium difficile infection. Initial mean total leukocyte count was higher in the hospitalized group at 8.40×109/L versus 6.31×109/L in the nonhospitalized group (P=0.049). All 13 patients presenting with fever had symptomatic resolution (P=0.002). The presence of C. difficile infection was correlated with persistent symptoms (OR 2.30 [0.95-5.58], P=0.067). The overall mortality rate among our cohort was 3.13% (4 patients). All deceased patients had secondary immune deficiency, and none had C. difficile coinfection. Presence of an immune deficiency increases the risk of hospitalization with norovirus infection. Absence of fever is associated with lower resolution and possibly may contribute to a persistent infectious state. Presence of concomitant C. difficile infection is correlated with a lower overall mortality rate. Copyright © 2017 Elsevier Inc. All rights reserved.

Legionella pneumophila community-acquired pneumonia (CAP) in a post-splenectomy patient with myelodysplastic syndrome (MDS).

Cunha, Burke A; Hage, Jean E

2012-01-01

Legionnaire's disease is a cause of community-acquired pneumonia (CAP) in normal hosts, but those with impaired cell-mediated immunity (CMI) and T-lymphocyte function are particularly predisposed to Legionella species CAP. Myelodysplastic syndrome (MDS) is a disorder of the elderly that is associated with impaired CMI. Cases of MDS or Legionella species CAP are rare. Splenectomized patients primarily have impaired humoral immunity and B-lymphocyte function, and, to a lesser extent, some decrease in CMI. For this reason, Legionnaire's disease has rarely been reported in splenectomized patients. We believe this to be the first reported case of Legionella pneumophila CAP in an asplenic patient with MDS. Copyright © 2012 Elsevier Inc. All rights reserved.

Bartter syndrome is a rare autosomal recessive disorder characterized by hypokalemia, salt loss, and metabolic alkalosis. Short stature is one of the clinical manifestations in these children. Although polyuria, polydipsia, hypokalemia, and salt loss may be responsible for growth retardation, the exact pathogenesis of short stature in Bartter syndrome is not known. In this study, we present three children diagnosed as having Bartter syndrome with short stature and growth hormone (GH) deficiency. After recombinant human growth hormone therapy (rhGH), their growth velocities were improved. These results indicate that GH deficiency may contribute to short stature in children with Bartter syndrome, and rhGH therapy would be an excellent adjunctive treatment for short children with this syndrome whose condition is resistant to conventional therapies in terms of growth.

To evaluate the economic impact of routine testing of human immune deficiency virus in antenatal settings. Many children are being infected with human immune deficiency virus through mother-to-child transmission of the virus. Most of these infections are preventable if the mothers' human immune deficiency virus status is identified in a timely manner and appropriate interventions put in place. Routine human immune deficiency virus testing is widely acclaimed as a strategy for universal access to human immune deficiency virus testing and is being adopted by developed and developing poor income countries without recourse to the economic impact. A systematic review of published articles. Extensive electronic searches for relevant journal articles published from 1998-2015 when countries began to implement routine antenatal HIV testing on their own were conducted in the following databases: Science Direct, MEDLINE, SCOPUS, JSTOR, CINAHL and PubMed with search terms as listed in Box 2. Manual searches were also performed to complement the electronic identification of high-quality materials. There were no geographical restrictions, but language was limited to English. Fifty-five articles were retrieved; however, ten were eligible and included in the review. The findings showed that many programmes involving routine human immune deficiency virus testing for pregnant women compared to the alternatives were cost-effective and cost saving. Data from the reviewed studies showed cost savings between $5,761.20-$3.69 million per case of previously undiagnosed maternal human immune deficiency virus-positive infection prevented. Overall, cost-effectiveness was strongly associated with the prevalence rate of human immune deficiency virus in the various settings. Routine human immune deficiency virus testing is both cost-effective and cost saving compared to the alternatives. However, there are wide variations in the methodological approaches to the studies.

Constitutional mismatch repair deficiency (CMMR-D) syndrome is characterised by a significantly increased risk for developing cancer in childhood. It arises when both parents have a mutation in the same mismatch repair gene and pass it on to their child. An 8-year-old girl was diagnosed with CMMR-D syndrome after she developed a brain tumour at the age of 4 and a T-cell non-Hodgkin lymphoma at the age of 6. She had multiple hyperpigmented skin lesions and died of myelodysplastic syndrome at the age of 11. In children with cancer CMMR-D syndrome can be recognized particularly if there are multiple primary malignancies and skin hyperpigmentations and hypopigmentations. The parents of these children are at high risk for colorectal and endometrial cancer (Lynch syndrome), amongst others.

An ongoing tragedy: the acquired immune deficiency syndrome (AIDS).

PubMed

Desai, B T

1989-01-01

The AIDS epidemic has, to date, had only a minimal impact in India; however, given the low health status of the population and the lack of adequate health care facilities, the emergence of AIDS on a wider scale would be devastating. India's human immunodeficiency virus (HIV) seropositivity rate now stands at about 2-3/1000 people tested. In what is suspected to be a racially motivated move, the Government of India has embarked on testing all foreign students (most of whom are from Africa) for HIV and is returning all those who test seropositive to their countries of origin. Of concern is the steady increase in HIV infection in professional blood donors (1.5/1000 in late 1988). Mandatory screening of donated blood is prohibitively expensive in India, and none of the 9 companies that manufacture blood products in India test their donors for HIV infection. Another concern is the finding that 1 of every 6 prostitutes in Bombay is infected with HIV. The response of the Indian Government to the AIDS threat has tended to be punitive toward AIDS victims rather than based on a sound preventive strategy. For example, the 1989 AIDS Prevention Bill forces individuals who are infected with HIV to reveal their past sexual partners, empowers authorities to hospitalize AIDS victims and drug addicts, and contains no provisions to protect the human and civil rights of AIDS victims. The mass media have treated AIDS in a sensationalized manner rather than presenting scientific information about the prevention and transmission of the disease. It is essential that the Government of India--and all world governments--realize that punitive measures will do little to reduce the spread of AIDS. Needed, instead, is a global prevention and control effort based on generosity and compassion.

Many children with HIV infection now survive into adulthood. This study explored the impact of vertically acquired HIV in the era of antiretroviral therapy on the development of humoral immunity. Natural and vaccine-related immunity to pneumococcus and B-cell phenotype was characterized and compared in three groups of young adults: those with vertically-acquired infection, those with horizontally acquired infection and healthy controls. Serotype-specific pneumococcal (Pnc) immunoglobulin M and G concentrations before and up to 1 year post-Pnc polysaccharide (Pneumovax) immunization were determined, and opsonophagocytic activity was analysed. B-cell subpopulations and dynamic markers of B-cell signalling, turnover and susceptibility to apoptosis were evaluated by flow cytometry. HIV-infected patients showed impaired natural Pnc immunity and reduced humoral responses to immunization with Pneumovax; this was greatest in those viraemic at time of the study. Early-life viral control before the age of 10 years diminished these changes. Expanded populations of abnormally activated and immature B-cells were seen in both HIV-infected cohorts. Vertically infected patients were particularly vulnerable to reductions in marginal zone and switched memory populations. These aberrations were reduced in patients with early-life viral control. In children with HIV, damage to B-cell memory populations and impaired natural and vaccine immunity to pneumococcus is evident in early adult life. Sustained viral control from early childhood may help to limit this effect and optimize humoral immunity in adult life.

Background Chronic Fatigue Syndrome (CFS) is a multifactorial disorder that affects various physiological systems including immune and neurological systems. The immune system has been substantially examined in CFS with equivocal results, however, little is known about the role of neutrophils and natural killer (NK) phenotypes in the pathomechanism of this disorder. Additionally the role of erythrocyte rheological characteristics in CFS has not been fully expounded. The objective of this present study was to determine deficiencies in lymphocyte function and erythrocyte rheology in CFS patients. Methods Flow cytometric measurements were performed for neutrophil function, lymphocyte numbers, NK phenotypes (CD56dimCD16+ and CD56brightCD16-) and NK cytotoxic activity. Erythrocyte aggregation, deformability and fibrinogen levels were also assessed. Results CFS patients (n = 10) had significant decreases in neutrophil respiratory burst, NK cytotoxic activity and CD56brightCD16- NK phenotypes in comparison to healthy controls (n = 10). However, hemorheological characteristic, aggregation, deformability, fibrinogen, lymphocyte numbers and CD56dimCD16+ NK cells were similar between the two groups. Conclusion These results indicate immune dysfunction as potential contributors to the mechanism of CFS, as indicated by decreases in neutrophil respiratory burst, NK cell activity and NK phenotypes. Thus, immune cell function and phenotypes may be important diagnostic markers for CFS. The absence of rheological changes may indicate no abnormalities in erythrocytes of CFS patients. PMID:20064266

Triple-negative breast cancer (TNBC) is associated with worse outcomes relative to other breast cancer subtypes. Chemotherapy remains the standard-of-care systemic therapy for patients with localized or metastatic disease, with few biomarkers to guide benefit. We will discuss recent advances in our understanding of two key biological processes in TNBC, homologous recombination (HR) DNA repair deficiency and host anti-tumor immunity, and their intersection. Recent advances in our understanding of homologous recombination (HR) deficiency, including FDA approval of PARP inhibitor olaparib for BRCA1 or BRCA2 mutation carriers, and host anti-tumor immunity in TNBC offer potential for new and biomarker-driven approaches to treat TNBC. Assays interrogating HR DNA repair capacity may guide treatment with agents inducing or targeting DNA damage repair. Tumor infiltrating lymphocytes (TILs) are associated with improved prognosis in TNBC and recent efforts to characterize infiltrating immune cell subsets and activate host anti-tumor immunity offer promise, yet challenges remain particularly in tumors lacking pre-existing immune infiltrates. Advances in these fields provide potential biomarkers to stratify patients with TNBC and guide therapy: induction of DNA damage in HR-deficient tumors and activation of existing or recruitment of host anti-tumor immune cells. Importantly, these advances provide an opportunity to guide use of existing therapies and development of novel therapies for TNBC. Efforts to combine therapies that exploit HR deficiency to enhance the activity of immune-directed therapies offer promise. HR deficiency remains an important biomarker target and potentially effective adjunct to enhance immunogenicity of 'immune cold' TNBCs.

The objective of the present study was to investigate whether dietary selenium (Se) deficiency would affect the expression of selenoprotein T (SelT) and immune response in the immune organs of broilers. Changes in expression of inflammatory cytokines and oxidative stress response caused by Se deficiency can lead to organism damage, which in turn leads to immune response. Sixty (1-day-old) broilers were divided into the control group and Se-deficiency group. Animal models with exudative diathesis were duplicated in the broilers by feeding them Se-deficient diet for 20 days. After the Se-deficient group exhibited symptoms of exudative diathesis, all the broilers were euthanized, and their immune organs were taken for analysis. The tissues including spleen, bursa of Fabricius, and thymus were treated to determine the pathological changes (including microscopic and ultramicroscopic), the messenger RNA (mRNA) expression levels of SelT and its synthetase (SecS and SPS1), cytokine mRNA expression levels, and antioxidant status. The microscopic and ultramicroscopic analyses showed that immune tissues were obviously injured in the Se-deficient group. The mRNA expression of SelT was decreased compared with that in the control group. Meanwhile, the mRNA expression levels of SecS and SPS1 were downregulated. In the Se-deficient group, the mRNA expression levels of IL-1R and IL-1β were higher than those of three control organs. Additionally, the IL-2 and INF-γ mRNA expression levels were lower than those of the control group. The activity of CAT was decreased, and the contents of H 2 O 2 and •OH were increased due to Se deficiency. Pearson method analysis showed that the expression of SelT had a positive correlation with IL-2, INF-γ, SecS, and SPS1 and a negative correlation with IL-1R and IL-1β. In summary, these data indicated that Se-deficient diet decreased the SelT expression and its regulation of oxidative stress, and it inhibited a pleiotropic mechanism of the

Toward immunogenetic studies of amphibian chytridiomycosis: Linking innate and acquired immunity

Recent declines in amphibian diversity and abundance have contributed significantly to the global loss of biodiversity. The fungal disease chytridiomycosis is widely considered to be a primary cause of these declines, yet the critical question of why amphibian species differ in susceptibility remains unanswered. Considerable evidence links environmental conditions and interspecific variability of the innate immune system to differential infection responses, but other sources of individual, population, or species-typical variation may also be important. In this article we review the preliminary evidence supporting a role for acquired immune defenses against chytridiomycosis, and advocate for targeted investigation of genes controlling acquired responses, as well as those that functionally bridge the innate and acquired immune systems. Immunogenetic data promise to answer key questions about chytridiomycosis susceptibility and host-pathogen coevolution, and will draw much needed attention to the importance of considering evolutionary processes in amphibian conservation management and practice. ?? 2009 by American Institute of Biological Sciences.

Creatine deficiency syndromes.

Schulze, Andreas

2013-01-01

The lack of creatine in the central nervous system causes a severe but treatable neurological disease. Three inherited defects, AGAT, GAMT, and CrT deficiency, compromising synthesis and transport of creatine have been discovered recently. Together these so-called creatine deficiency syndromes (CDS) might represent the most frequent metabolic disorders with a primarily neurological phenotype. Patients with CDS present with global developmental delays, mental retardation, speech impairment especially affecting active language, seizures, extrapyramidal movement disorder, and autism spectrum disorder. The two defects in the creatine synthesis, AGAT and GAMT, are autosomal recessive disorders. They can be diagnosed by analysis of the creatine, guanidinoacetate, and creatinine in body fluids. Treatment is available and, especially when introduced in infancy, has a good outcome. The defect of creatine transport, CrT, is an X-linked condition and perhaps the most frequent reasons for X-linked mental retardation. Diagnosis is made by an increased ratio of creatine to creatinine in urine, but successful treatment still needs to be explored. CDS are under-diagnosed because easy to miss in standard diagnostic workup. Because CDS represent a frequent cause of cognitive and neurological impairment that is treatable they warrant consideration in the workup for genetic mental retardation syndromes, for intractable seizure disorders, and for neurological diseases with a predominant lack of active speech.

Lynch syndrome is the most common form of hereditary colorectal carcinoma. However, establishing the diagnosis of Lynch syndrome is challenging, and ancillary studies that distinguish between sporadic DNA mismatch repair (MMR) protein deficiency and Lynch syndrome are needed, particularly when germline mutation studies are inconclusive. The aim of this study was to determine if MMR protein-deficient non-neoplastic intestinal crypts can help distinguish between patients with and without Lynch syndrome. We evaluated the expression of MMR proteins in non-neoplastic intestinal mucosa obtained from colorectal surgical resection specimens from patients with Lynch syndrome-associated colorectal carcinoma (n = 52) and patients with colorectal carcinoma without evidence of Lynch syndrome (n = 70), including sporadic MMR protein-deficient colorectal carcinoma (n = 30), MMR protein proficient colorectal carcinoma (n = 30), and "Lynch-like" syndrome (n = 10). MMR protein-deficient non-neoplastic colonic crypts were identified in 19 of 122 (16%) patients. MMR protein-deficient colonic crypts were identified in 18 of 52 (35%) patients with Lynch syndrome compared to only 1 of 70 (1%) patients without Lynch syndrome (p < 0.001). This one patient had "Lynch-like" syndrome and harbored two MSH2-deficient non-neoplastic colonic crypts. MMR protein-deficient non-neoplastic colonic crypts were not identified in patients with sporadic MMR protein-deficient or MMR protein proficient colorectal carcinoma. Our findings suggest that MMR protein-deficient colonic crypts are a novel indicator of Lynch syndrome, and evaluation for MMR protein-deficient crypts may be a helpful addition to Lynch syndrome diagnostics.

Mismatch repair-deficient endometrial carcinomas are optimal candidates for immunotherapy given their high neoantigen loads, robust lymphoid infiltrates, and frequent PD-L1 expression. However, co-opting the PD-1/PD-L1 pathway is just one mechanism that tumors can utilize to evade host immunity. Another immune modulatory molecule that has been demonstrated in endometrial carcinoma is indoleamine 2,3-dioxygenase (IDO). We herein evaluate IDO expression in 60 endometrial carcinomas and assess results in relation to PD-L1 and mismatch repair status. IDO immunohistochemistry was performed on 60 endometrial carcinomas (20 Lynch syndrome (LS)-associated, 20 MLH1 promoter hypermethylated, and 20 mismatch repair-intact). Eight-five percent of endometrial carcinomas showed IDO tumor staining in >1% of cells. Twenty-five percent were positive in >25% of tumor cells and only 7% exceeded 50% staining. Mismatch repair-deficient cancers were more likely than mismatch repair-intact cancers to be >25% IDO-positive (35% vs. 5% p = 0.024). Differences were amplified when Lynch syndrome-associated cases were evaluated in isolation (50% Lynch syndrome-associated vs. 10% mismatch repair-intact and MLH1-hypermethylated, p = 0.001). Of the four cases showing >50% staining, three were Lynch syndrome-associated and one was MLH1-hypermethylated; no mismatch repair-intact cases had >50% staining. Forty-three percent of IDO-positive tumors were also positive for PD-L1, whereas only two cases showed tumoral PD-L1 in the absence of IDO. In summary, IDO expression is prevalent in endometrial carcinomas and diffuse staining is significantly more common in mismatch repair-deficient cancers, particularly Lynch syndrome-associated cases. Given that the majority of PD-L1 positive cancers also express IDO, synergistic combination therapy with anti-IDO and anti-PD1/PD-L1 may be relevant in this tumor type. Furthermore, anti-IDO therapy may be an option for a small subset of mismatch repair

Acute thiamine deficiency and refeeding syndrome: Similar findings but different pathogenesis.

Refeeding syndrome can occur in several contexts of relative malnutrition in which an overaggressive nutritional support is started. The consequences are life threatening with multiorgan impairment, and severe electrolyte imbalances. During refeeding, glucose-involved insulin secretion causes abrupt reverse of lipolysis and a switch from catabolism to anabolism. This creates a sudden cellular demand for electrolytes (phosphate, potassium, and magnesium) necessary for synthesis of adenosine triphosphate, glucose transport, and other synthesis reactions, resulting in decreased serum levels. Laboratory findings and multiorgan impairment similar to refeeding syndrome also are observed in acute thiamine deficiency. The aim of this study was to determine whether thiamine deficiency was responsible for the electrolyte imbalance caused by tubular electrolyte losses. We describe two patients with leukemia who developed acute thiamine deficiency with an electrolyte pattern suggestive of refeeding syndrome, severe lactic acidosis, and evidence of proximal renal tubular dysfunction. A single thiamine administration led to rapid resolution of the tubular dysfunction and normalization of acidosis and electrolyte imbalance. This demonstrated that thiamine deficiency was responsible for the electrolyte imbalance, caused by tubular electrolyte losses. Our study indicates that, despite sharing many laboratory similarities, refeeding syndrome and acute thiamine deficiency should be viewed as separate entities in which the electrolyte abnormalities reported in cases of refeeding syndrome with thiamine deficiency and refractory lactic acidosis may be due to renal tubular losses instead of a shifting from extracellular to intracellular compartments. In oncologic and malnourished patients, individuals at particular risk for developing refeeding syndrome, in the presence of these biochemical abnormalities, acute thiamine deficiency should be suspected and treated because it promptly

Baraitser and Winter syndrome with growth hormone deficiency.

2014-01-01

Baraitser-Winter syndrome (BWS), first reported in 1988, is apparently due to genetic abnormalities that are still not well-defined, although many gene abnormalities are already discovered and de novo missense changes in the cytoplasmic actin-encoding genes (called ACTB and ACTG1) have been recently discovered. The syndrome combines facial and cerebral malformations. Facial malformations totally or partially present in the same patient are: Iris coloboma, bilateral ptosis, hypertelorism, broad nasal bridge, and prominent epicanthic folds. The various brain malformations are probably responsible for growth and mental retardation. To the best of our knowledge, the syndrome is very rare as few cases have been reported so far. Our aim was to describe a child with a phenotype that looks like BWS with proved partial growth hormone (GH) deficiency which was not reported before. A girl aged 7-year-old of consanguineous parents was referred for short stature and mental retardation. Clinical examination showed dwarfism and a delay in her mental development. Other clinical features included: Strabismus, epicanthic folds, broad nasal bridge, and brain anomalies such as lissencephaly, bilateral hygroma, and cerebral atrophy. Hormonal assessment showed partial GH deficiency without other endocrine disorders. Our case looks exactly like BWS. However, apart from facial and cerebral abnormalities, there is a partial GH deficiency which can explain the harmonious short stature. This case seems worth to be reported as it adds GH deficiency to the very rare syndrome.

Autoimmune diseases such as systemic lupus erythematosus (SLE) are associated with increased cardiovascular disease and reduced plasma high-density lipoprotein (HDL) levels. HDL mediates cholesterol efflux from immune cells via the ATP binding cassette transporters A1 and G1 (ABCA1/G1). The significance of impaired cholesterol efflux pathways in autoimmunity is unknown. We observed that Abca1/g1-deficient mice develop enlarged lymph nodes (LNs) and glomerulonephritis suggestive of SLE. This lupus-like phenotype was recapitulated in mice with knockouts of Abca1/g1 in dendritic cells (DCs), but not in macrophages or T cells. DC-Abca1/g1 deficiency increased LN and splenic CD11b + DCs, which displayed cholesterol accumulation and inflammasome activation, increased cell surface levels of the granulocyte macrophage-colony stimulating factor receptor, and enhanced inflammatory cytokine secretion. Consequently, DC-Abca1/g1 deficiency enhanced T cell activation and T h 1 and T h 17 cell polarization. Nlrp3 inflammasome deficiency diminished the enlarged LNs and enhanced T h 1 cell polarization. These findings identify an essential role of DC cholesterol efflux pathways in maintaining immune tolerance. Copyright © 2017 Elsevier Inc. All rights reserved.

To explore the impedance characteristics of ear acupoints in stroke patients with excess or deficiency syndrome, and to provide basis data for objective study of the syndromes of stroke. The data of electrical characteristics of ear acupoints in stroke patients and healthy people were collected, and excess syndrome and deficiency syndrome of stroke were identified by quantifying the syndromes of stroke using scales. The differences in impedance characteristics of ear acupoints between stroke patients and healthy people were analyzed, and the differences in impedance characteristics of ear acupoints between stroke patients with excess syndrome and stroke patients with deficiency syndrome were analyzed too. The correlation among impedance characteristics of ear acupoints, stroke and the syndromes was also analyzed. There were significant differences in impedance characteristics of ear acupoints between stroke patients and healthy people (P<0.05,P<0.01). The ear acupoints CO12 (Gan) and CO13 (Pi) had a significant role in diagnosing stroke as compared with CO18 (Neifenmi), AT3.4.AH12i (Naogan), CO10 (Shen), TG2p (Shenshangxian), AH6a (Jiaogan), AT4 (Pizhixia), and CO15 (Xin). There were significant differences in impedance characteristics of ear acupoints between stroke patients with excess syndrome and stroke patients with deficiency syndrome (P<0.05, P<0.01). The ear acupoints AH6a (Jiaogan) and CO10 (Shen) played an important role in differentiation diagnosis of excess syndrome and deficiency syndrome of stroke, followed by CO18 (Neifenmi), TF4 (Shenmen) and TG2p (Shenshangxian). Some ear acupoints with diagnostic value for stroke may provide basis of objective research for stroke diagnosis as well as identifying excess syndrome and deficiency syndrome of stroke.

Light chain proximal tubulopathy is a rarely reported entity associated with plasma cell dyscrasia that classically manifests as acquired Fanconi syndrome and is characterized by the presence of κ-restricted crystals in the proximal tubular cytoplasm. We herein present a case of multiple myeloma with Fanconi syndrome and acute kidney injury due to light chain proximal tubulopathy with light chain cast nephropathy. Prominent phagolysosomes and numerous irregularly shaped inclusions with a fibrillary matrix in the cytoplasm of the proximal tubules were identified on electron microscopy. A monotypic light chain of the λ type was detected in the distal tubular casts, proximal tubular cytoplasmic lysosomes and fibrillary inclusions on immunofluorescence and immune electron microscopy. This case underscores the importance of conducting careful ultrastructural investigations and immunocytologic examinations of light chains for detecting and diagnosing light chain proximal tubulopathy.

To study the qi deficiency syndrome distribution and quality of life (QOL) of patients with advanced non-small cell lung cancer (NSCLC). A questionnaire survey was conducted in 120 patients with advanced NSCLC using the QOL scale "Functional Assessment of Cancer Therapy" (FACT-L) (Version 4.0). Meanwhile, syndrome typing was performed. On the basis of results of syndrome typing, patients of different syndrome types were grouped and compared, thus studying the distribution of advanced NSCLC patients of qi deficiency syndrome and qi deficiency syndrome correlated QOL features. Qi deficiency, blood stasis, yin deficiency, phlegm and dampness dominated in syndrome types of the 120 patients with advanced NSCLC. Of syndrome types accounting for larger ratios in 112 patients, pure qi deficiency syndrome accounted for 30.36% (34 cases), qi deficiency and blood stasis syndrome for 18. 75% (21 cases), both qi and yin deficiency syndrome for 10. 71% (12 cases). There was no correlation between the appearance of qi deficiency syndrome and patients' age, sex, pathological typing (adenocarcinoma/squamous carcinoma), or the disease duration. NSCLC patients in phase IV were mostly complicated with qi deficiency syndrome (P<0.05). Scores of physical states, emotional states, functional states, and total scores in the FACT-L scale were lower in those complicated with qi deficiency syndrome (89 cases) than in those without complicated qi deficiency syndrome (31 cases), showing statistical difference (P<0.01, P<0.05). The scores of the lung cancer specific module (additional concerns) in the FACT-L scale showed statistical difference, sequenced as qi deficiency and blood stasis syndrome > pure qi deficiency syndrome > both qi and yin deficiency syndrome (P<0.05). Qi deficiency syndrome is the main syndrome of advanced NSCLC. The QOL of advanced NSCLC patients complicated with qi deficiency syndrome was poorer than those without complicated qi deficiency syndrome. Besides, along with

Human immunodeficiency virus vaccination and pre-exposure prophylaxis represent two different emerging preventive tools. Google Trends was used to assess the public interest toward these tools in terms of digital activities. Worldwide web searches concerning the human immunodeficiency virus vaccine represented 0.34 percent, 0.03 percent, and 46.97 percent of human immunodeficiency virus, acquired immune deficiency syndrome, and human immunodeficiency virus/acquired immune deficiency syndrome treatment-related Google Trends queries, respectively. Concerning temporal trends, digital activities were shown to increase from 0 percent as of 1 January 2004 percent to 46 percent as of 8 October 2017 with two spikes observed in May and July 2012, coinciding with the US Food and Drug Administration approval. Bursts in search number and volume were recorded as human immunodeficiency virus vaccine trials emerged. This search topic has decreased in the past decade in parallel to the increase in Truvada-related topics. Concentrated searches were noticed among African countries with high human immunodeficiency virus/acquired immune deficiency syndrome prevalence. Stakeholders should take advantage of public interest especially in preventive medicine in high disease burden countries.

An enlargement of the thymus suggesting a tumor was discovered in a 28-year-old man who had early-stage acquired immune deficiency syndrome. A biopsy was performed. The adipose involuted thymus, with persistence of many Hassall's corpuscles, was judged to be a large lymphoid follicular hyperplasia. This follicular hyperplasia was similar to that previously described for lymph nodes, spleen, and other lymphoid tissues at earlier stages of human immunodeficiency virus infection, before the development of acquired immune deficiency syndrome. Human immunodeficiency virus RNA and p24 human immunodeficiency virus protein were detected in the hyperplastic germinal centers (lymphocytes and follicular dendritic infected cells), and also in many cells that may have been either lymphocytes and/or epithelial cells in the interfollicular areas. The tissue was negative for Epstein-Barr virus DNA sequences, as determined by the polymerase chain reaction. These observations identify the first state of infection of the thymus in a human immune deficiency virus-infected adult, preceding the severe involution with lymphoid depletion observed in all fatal cases of acquired immunodeficiency syndrome in which the thymus has been analyzed.

The Primary Immune Deficiency Treatment Consortium (PIDTC) is a network of 33 centers in North America that study the treatment of rare and severe primary immunodeficiency diseases. Current protocols address the natural history of patients treated for severe combined immunodeficiency (SCID), Wiskott-Aldrich syndrome, and chronic granulomatous disease through retrospective, prospective, and cross-sectional studies. The PIDTC additionally seeks to encourage training of junior investigators, establish partnerships with European and other International colleagues, work with patient advocacy groups to promote community awareness, and conduct pilot demonstration projects. Future goals include the conduct of prospective treatment studies to determine optimal therapies for primary immunodeficiency diseases. To date, the PIDTC has funded 2 pilot projects: newborn screening for SCID in Navajo Native Americans and B-cell reconstitution in patients with SCID after hematopoietic stem cell transplantation. Ten junior investigators have received grant awards. The PIDTC Annual Scientific Workshop has brought together consortium members, outside speakers, patient advocacy groups, and young investigators and trainees to report progress of the protocols and discuss common interests and goals, including new scientific developments and future directions of clinical research. Here we report the progress of the PIDTC to date, highlights of the first 2 PIDTC workshops, and consideration of future consortium objectives. Published by Mosby, Inc.

Acquired angioedema is a rare disease caused by a deficiency of C1 esterase inhibitor with recurrent swelling symptoms. It may occur in the course of lymphoproliferative disorders or autoimmune diseases. Symptoms resemble hereditary angioedema, and the only differentiating features is negative family history, late onset of symptoms and accompanying lymphoproliferative disorder. The aim of the study was to analyze the cases of acquired angioedema. The retrospective analysis of 341 patients from the registry of patients with C1 inhibitor deficiency. Results: We identified 4 patients among 119 with HAE (3.57%) diagnosed in this same period of time 2012-2016 who fulfilled the criteria of acquired edema. In two cases the primary reason of angioedema was lymphoproliferive disease, in two monoclonal gammapathy of unknown reason. We analyzed also the results of laboratory tests C4, C1 inhibitor, C1q. In all cases the face was dominated localization. After the treatment of primary lymphoproliferive disease, in two cases, we observed total remission of angioedema. Only one patient with gammapathy require treatment with C1 inhibitor during the attacks. In these case we observed both plasma deriver, and recombinant C1 inhibitor were effective.

The therapeutic effects of fullerene derivatives on many models of inflammatory disease have been demonstrated. The anti-inflammatory mechanisms of these nanoparticles remain to be elucidated, though their beneficial roles in allergy and autoimmune diseases suggest their suppressive potential in acquired immunity. Here, we evaluated the effects of C60 pyrrolidine tris-acid (C60-P) and polyhydroxylated fullerene (C60(OH)36) on the acquired immune response in vitro and in vivo. In vitro, both C60 derivatives had dose-dependent suppressive effects on T cell receptor-mediated activation of T cells and antibody production by B cells under anti-CD40/IL-4 stimulation, similar to the actions of the antioxidant N-acetylcysteine. In addition, C60-P suppressed ovalbumin-specific antibody production and ovalbumin-specific T cell responses in vivo, although T cell-independent antibodies responses were not affected by C60-P. Together, our data suggest that fullerene derivatives can suppress acquired immune responses that require T cells.

Scope Zinc deficiency results in immune dysfunction and promotes systemic inflammation. The objective of this study was to examine the effects of zinc deficiency on cellular immune activation and epigenetic mechanisms that promote inflammation. This work is potentially relevant to the aging population given that age-related immune defects, including chronic inflammation, coincide with declining zinc status. Methods and results An in vitro cell culture system and the aged mouse model were used to characterize immune activation and DNA methylation profiles that may contribute to the enhanced proinflammatory response mediated by zinc deficiency. Zinc deficiency up-regulated cell activation markers ICAM1, MHC class II, and CD86 in THP1 cells, that coincided with increased IL1β and IL6 responses following LPS stimulation. A decreased zinc status in aged mice was similarly associated with increased ICAM1 and IL6 gene expression. Reduced IL6 promoter methylation was observed in zinc deficient THP1 cells, as well as in aged mice and human lymphoblastoid cell lines derived from aged individuals. Conclusion Zinc deficiency induced inflammatory response in part by eliciting aberrant immune cell activation and altered promoter methylation. Our results suggested potential interactions between zinc status, epigenetics, and immune function, and how their dysregulation could contribute to chronic inflammation. PMID:25656040

Fighting against acquired immunodeficiency syndrome with Chinese medicine: a perspective from China.

Continuing expansion of the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) pandemic has been recognized as an exceptional challenge to global health. Taking highly active antiretroviral treatment (HAART), a confirmed effective treatment, has its limitations. While a much cheaper and potential treatment-the Chinese medicine (CM) has not been paid enough attention from the worldwide. We explained the CM viewpoints about pathology and etiology to answer some questions about whether and how CM can treat AIDS. Some herbal formulae and their targeted patterns and common symptoms were also introduced. Chinese government has realized the important role of CM as an independent therapy for early management, bolstering immune-system functions depressed by HIV, and has funded large randomized double-blind controlled clinical trials to more accurately assess the benefits, and valued the fundamental research to establish a quantitative standardization of pattern diagnosis. Researchers of CM are looking for cooperation with all the world's top experts in the areas of AIDS and immunity to strive for victories in the fight against AIDS.

Dengue virus (DENV) causes a spectrum of diseases ranging from self-limiting dengue fever to severe conditions such as haemorrhagic fever and dengue shock syndrome. Antibody-dependent enhancement (ADE) is thought to explain the occurrence of severe dengue whereby pre-existing binding but non-neutralising antibodies enhance DENV infection. The ADE phenomenon is supported by epidemiological findings that infants that born to dengue immune mothers are at greater risk to develop severe dengue upon primary infection. The role of maternally acquired dengue-specific antibodies in disease enhancement was recently recapitulated in a mouse model where mice born to DENV1-immune mothers experienced enhanced disease severity upon DENV2 infection. Here, this study investigates the relative contribution of maternal dengue-specific antibodies acquired during gestation and breastfeeding in dengue disease. Using a surrogate breastfeeding mother experimental approach, we showed that majority of the maternal dengue-specific antibodies were acquired during breastfeeding and conferred an extended enhancement window. On the other hand, in the context of homologous infection, breastfeeding conferred protection. Furthermore, measurement of dengue-specific antibody titres over time in mice born to dengue immune mothers revealed a biphasic pattern of antibody decay as reported in humans. Our work provides evidence of the potential contribution of breast milk-acquired dengue-specific IgG antibodies in enhancement and protection against dengue. Should such contribution be established in humans as well, it may have important implications for the development of guidelines to dengue-immune breastfeeding mothers.

Changes in serum gamma globulin levels, numbers of replete female ticks and engorged tick mass were used as parameters to monitor the acquired immune response (antibody mediated immune response) elicited by Rhipicephalus appendiculatus adult tick infestations. Three consecutive Rhipicephalus appendiculatus adult tick infestations were applied to South African Indigenous goats (Nguni), Saanen goats and cross-bred goats (Saanen goats crossed with South African Indigenous goats [Nguni]) under laboratory conditions. During the three consecutive Rhipicephalus appendiculatus adult tick infestations the serum gamma globulin levels increased in all three breeds, whilst the mean replete female tick numbers and engorged tick mass decreased. Even though all three goat breeds exhibited an acquired immune response, the South African Indigenous goats (Nguni) response was significantly higher than that of the Saanen and cross-bred goats. However, the acquired immune response elicited by Saanen goats was significantly lower when compared with cross-bred goats.

Chromosome instability syndromes are a group of inherited conditions associated with chromosomal instability and breakage, often leading to immunodeficiency, growth retardation and increased risk of malignancy. We performed exome sequencing on a girl with a suspected chromosome instability syndrome that manifested as growth retardation, microcephaly, developmental delay, dysmorphic features, poikiloderma, immune deficiency with pancytopenia, and myelodysplasia. She was homozygous for a previously reported splice variant, c.4444 + 3A > G in the POLE1 gene, which encodes the catalytic subunit of DNA polymerase E. This is the second family with POLE1-deficency, with the affected individual demonstrating a more severe phenotype than previously described.

Normal functioning of the human body requires a balance between nutritional intake and metabolism, and imbalances manifest as nutritional deficiencies or excess. Nutritional deficiency states are associated with social factors (war, poverty, famine, and food fads), medical illnesses with malabsorption (such as Crohn disease, cystic fibrosis, and after bariatric surgery), psychiatric illnesses (eating disorders, autism, alcoholism), and medications. Nutritional excess states result from inadvertent or intentional excessive intake. Cutaneous manifestations of nutritional imbalance can herald other systemic manifestations. This contribution discusses nutritional deficiency and excess syndromes with cutaneous manifestations of particular interest to clinical dermatologists. Copyright © 2010. Published by Elsevier Inc.

Neurological complications in patients with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS) are still common, even in the era of highly active antiretroviral therapy. Opportunistic infections, immune reconstitution, the virus itself, antiretroviral drugs and neurocognitive disorders have to be considered when establishing the differential diagnosis. Toxoplasmic encephalitis remains the major cause of space-occupying lesions in the brain of patients with HIV/AIDS; however, spinal cord involvement has been reported infrequently. Here, we review spinal cord toxoplasmosis in HIV infection and illustrate the condition with a recent case from our hospital. We suggest that most patients with HIV/AIDS and myelitis with enhanced spine lesions, multiple brain lesions and positive serology for Toxoplasma gondii should receive immediate empirical treatment for toxoplasmosis, and a biopsy should be performed in those cases without clinical improvement or with deterioration.

Objective In recent years, vitamin D has been shown to possess a wide range of immunomodulatory effects. Although there is extensive amount of research on vitamin D, we lack a comprehensive understanding of the prevalence of vitamin D deficiency or the mechanism by which vitamin D regulates the human immune system. This study examined the prevalence and correlates of vitamin D deficiency and the relationship between vitamin D and the immune system in healthy individuals. Methods Healthy individuals (n = 774) comprised of European-Americans (EA, n = 470), African–Americans (AA, n = 125), and Native Americans (NA, n = 179) were screened for 25-hydroxyvitamin D [25(OH)D] levels by ELISA. To identify the most noticeable effects of vitamin D on the immune system, 20 EA individuals with severely deficient (<11.3 ng/mL) and sufficient (>24.8 ng/mL) vitamin D levels were matched and selected for further analysis. Serum cytokine level measurement, immune cell phenotyping, and phosphoflow cytometry were performed. Results Vitamin D sufficiency was observed in 37.5% of the study cohort. By multivariate analysis, AA, NA, and females with a high body mass index (BMI, >30) demonstrate higher rates of vitamin D deficiency (p<0.05). Individuals with vitamin D deficiency had significantly higher levels of serum GM-CSF (p = 0.04), decreased circulating activated CD4+ (p = 0.04) and CD8+ T (p = 0.04) cell frequencies than individuals with sufficient vitamin D levels. Conclusion A large portion of healthy individuals have vitamin D deficiency. These individuals have altered T and B cell responses, indicating that the absence of sufficient vitamin D levels could result in undesirable cellular and molecular alterations ultimately contributing to immune dysregulation.

We describe a 65-year-old Thai woman who developed cytomegalovirus retinitis (CMVR) in the setting of Good syndrome-a rare, acquired partial immune deficiency caused by thymoma. The patient subsequently developed vitritis with cystoid macular edema (CME) similar to immune recovery uveitis (IRU) despite control of the retinitis with antiviral agents. A comprehensive review of the literature through December, 2014, identified an additional 279 eyes of 208 patients with CMVR in the absence of human immunodeficiency virus (HIV) infection. Including our newly reported case, 9 of the 208 patients (4.3 %) had Good syndrome. Twenty-one of the 208 patients (10.1 %) had CMVR related to intraocular or periocular corticosteroid administration. The remaining 178 patients (85.6 %) acquired CMVR from other causes. Within the subset of patients who did not have Good syndrome or did not acquire CMVR followed by intraocular or periocular corticosteroid administration, there were many other factors contributing to a decline in immune function. The most common included age over 60 years (33.1 %), an underlying malignancy (28.7 %), a systemic autoimmune disorder requiring systemic immunosuppression (19.1 %), organ (15.2 %) or bone marrow (16.3 %) transplantation requiring systemic immunosuppression, and diabetes mellitus (6.1 %). Only 4.5 % of the patients had no identifiable contributor to a decline in immune function. While the clinical features of CMVR are generally similar in HIV-negative and HIV-positive patients, the rates of moderate to severe intraocular inflammation and of occlusive retinal vasculitis appear to be higher in HIV-negative patients.

Background Subjects with glucose-6-phosphate dehydrogenase (G6PD) deficiency may be more susceptible to infections due to impaired leukocyte bactericidal activity. The disorder is common in the Mediterranean area. The aim of this study was to investigate whether G6PD deficiency may be a risk factor for acquiring H. pylori infection. Methods We performed a retrospective study. Data from clinical records of 6565 patients (2278 men and 4287 women, median age 51, range 7‒94) who underwent upper endoscopy between 2002 and 2014 were collected. H. pylori status, assessed by histology plus rapid urease test or 13C-urea breath test, and G6PD status were also reported. A multiple logistic regression model was used to investigate the association between G6PD deficiency and H. pylori infection. Results Enzyme deficiency was detected in 12% (789/6565) of the entire cohort, and more specifically in 8.3% of men and in 14.0% of women. Overall, the proportion of patients positive for H. pylori was 50.6% and 51.5% among G6PD deficient and non-deficient patients (χ² = 0.271; p = 0.315). Moreover, among G6PD-deficient and normal patients the frequency of previous H. pylori infection was similar. After adjustment for age and gender the risk for acquiring H. pylori infection was similar in G6PD-deficient and normal patients. Only age was a strong statistically significant risk predictor. Conclusions These results demonstrate for the first time that G6PD deficiency does not enhance patients’ susceptibility to acquire H. pylori infection in Sardinia. PMID:27467818

Decreased IgG subclass levels in pyogenic infections and immunocompromised situations have been described. A study was made to determine IgG subclass levels in four groups of 68 Hispanic patients. The first group consisted of 25 terminal patients with AIDS, the second group of 20 i.v. drug abusers, and the third group of eight hospital patients with neither a diagnosis of AIDS/ARC nor a history of i.v. drug abuse. IgG subclass levels of these 53 cases were compared with those of a fourth group of 15 normal controls. The total IgG, IgA, and IgM levels as well as the four IgG subclass concentrations were measured by radial immunodiffusion using appropriate standards and specific antisera. The first two groups had similar values, with an average IgG level of 10.37 g/liter; IgA, 2.68; and IgM, 1.78; subclass levels were IgG1, 6.68 g/liter; IgG2, 2.77; IgG3, 0.34; and IgG4, 0.68. These were significantly lower than those of controls, except for IgG4. Determination of minor subclasses may offer some possibilities for immunomodulation and therapy and could be useful in terms of prognosis.

The brunt of the human immunodeficiency virus infection/the acquired immunodeficiency syndrome is largely borne by communities in sub-Saharan Africa. We describe renal disease in Nigerians with the acquired immunodeficiency syndrome. Consecutive patients with the acquired immunodeficiency syndrome (AIDS) seen in the infections unit of the Jos University Teaching Hospital and a similar group of healthy controls were evaluated for renal disease. Subjects with past history of renal disease, hypovolemia, hypertension, diabetes mellitus and/or a documented fever were excluded from the study. Of the 79 patients with the acquired immunodeficiency syndrome and 57 controls studied, renal disease was present in 41 (51.8%) of the patients in the AIDS group and 7 (12.2%) of controls. While 15 (19%) of the AIDS group had azotemia alone and 20 (25.3%) had proteinuria alone, 6 (7.6%) had azotemia and proteinuria. The mean protein excretion/24 hours was significantly higher in the AIDS group compared to controls, (2.99 +/- 54 g and 0.56 +/- 0.12 g respectively, p = 0.001), while the GFR was significantly higher in controls compared to the study group (103.30 +/- 37.78 and 68.03 +/- 37.55 respectively, p = 0.004). Subjects in the AIDS group with renal disease had a significantly longer duration of illness compared to those without (12.33 +/- 8.67 months and 7.28 +/- 7.78 months respectively, p = 0.008). Age and serum CD4+ cell counts were similar in patients with and without renal disease in the AIDS group. Renal disease is a common complication of acquired immunodeficiency syndrome, the duration of illness being strongly associated with its presence.

Classic Bartter syndrome complicated with profound growth hormone deficiency: a case report

PubMed Central

2013-01-01

Introduction Classic Bartter syndrome is a salt-wasting tubulopathy caused by mutations in the CLCNKB (chloride channel Kb) gene. Although growth hormone deficiency has been suggested as a cause for persistent growth failure in patients with classic Bartter syndrome, in our opinion the diagnoses of growth hormone deficiency has been unconvincing in some reports. Moreover, Gitelman syndrome seems to have been confused with Bartter syndrome in some cases in the literature. In the present work, we describe a new case with CLCNKB gene mutations and review the reported cases of classic Bartter syndrome associated with growth hormone deficiency. Case presentation Our patient was a Japanese boy diagnosed as having classic Bartter syndrome at eight months of age. The diagnosis of Bartter syndrome was confirmed by CLCNKB gene analysis, which revealed compound heterozygous mutations with deletion of exons 1 to 3 (derived from his mother) and ΔL130 (derived from his father). His medical therapy consisted of potassium (K), sodium chloride, spironolactone, and anti-inflammatory agents; this regime was started at eight months of age. Our patient was very short (131.1cm, -4.9 standard deviation) at 14.3 years and showed profoundly impaired growth hormone responses to pharmacological stimulants: 0.15μg/L to insulin-induced hypoglycemia and 0.39μg/L to arginine. His growth response to growth hormone therapy was excellent. Conclusions The present case strengthens the association between classic Bartter syndrome and growth hormone deficiency. We propose that growth hormone status should be considered while treating children with classic Bartter syndrome. PMID:24377430

The authors describe a 3-year-old female, diagnosed with GLUT1 deficiency Syndrome, with a previously unreported mutation in exon 7 of the SLC2A1 gene: c.968_972 + 3del P. (Val323Alafs*53), characterized by a classic phenotypic of acquired microcephaly, developmental delay, ataxia, spasticity, and epilepsy. Ketogenic diet was started at the age of 30 months with epilepsy improvement. She presented paroxysmal ocular movements in the first 12 months of life, recently defined as "aberrant gaze saccades", that are present in the early phase of visual system development, being one of the first disease signs, but easily disregarded. Recognizing these particular ocular movements would allow an early diagnosis, followed by ketogenic diet implementation, improving significantly the prognosis and the neurological development of those children.

Growth hormone deficiency: an update.

Growth hormone (GH) deficiency (GHD) in humans manifests differently according to the individual developmental stage (early after birth, during childhood, at puberty or in adulthood), the cause or mechanism (genetic, acquired or idiopathic), deficiency intensity and whether it is the only pituitary-affected hormone or is combined with that of other pituitary hormones or forms part of a complex syndrome. Growing knowledge of the genetic basis of GH deficiency continues to provide us with useful information to further characterise mutation types and mechanisms for previously described and new candidate genes. Despite these advances, a high proportion of GH deficiencies with no recognisable acquired basis continue to be labelled as idiopathic, although less frequently when they are congenital and/or familial. The clinical and biochemical diagnoses continue to be a conundrum despite efforts to harmonise biochemical assays for GH and IGF-1 analysis, probably because the diagnosis based on the so-called GH secretion stimulation tests will prove to be of limited usefulness for predicting therapy indications.

A case of bilateral progressive outer retinal necrosis occurred after herpes zoster ophthalmicus in a patient with acquired immunodeficiency syndrome. This case does not correspond to the classical picture of progressive outer retinal necrosis. The disease led to blindness despite intravenous therapy with acyclovir and foscarnet. PCR could not identify any virus in the aqueous humour, but VZV is evidenced in cerebrospinal fluid. Acute retinal necrosis is now clearly defined by the American Uveitis Society, which should allow to determine its incidence and risk factors. Herpes zoster usually precedes the acute outer retinal necrosis. The infectious theory (VZV, HSV, CMV) widely prevails over the immune theory. We prefer the virus genome identification in the aqueous humor or in the vitreous by PCR to confirm diagnosis rather than the specific antibody titration. Therapy consists in acyclovir, foscarnet and ganciclovir. But whatever the treatment, the visual prognosis is poor.

In recent years, metabolic syndrome, obesity, diabetes and cardiovascular disease has had a tremendous elevation growth. Many studies have demonstrated negative correlation between vitamin D deficiency and indexes of metabolic syndrome in obese patients. This study was designed to find the relation between vitamin D deficiency and markers of metabolic syndrome among overweight and obese adults referred to obesity center of Shahid Sadoughi hospital in 2014. Eighty-nine overweight and obese adults (79 women and 10 men), who 13 subjects were overweight and 76 subjects were obese were recruited in this cross-sectional study. Total cholesterol, high-density lipoprotein cholesterol, triglyceride, plasma glucose and vitamin D were measured. IDF criteria were used for identifying subjects with metabolic syndrome. Demographic questionnaire was completed. Statistical analysis was performed using SPSS version 16.0. Fisher exact test, logistic regression, and Spearman correlation coefficient were used. The frequency of vitamin D deficiency was 93.2%. According to IDF criteria, the frequency of metabolic syndrome was 36%. There was no significant relationship between vitamin D deficiency and metabolic syndrome. Among metabolic syndrome indicators, there was a significant direct relationship between vitamin D level with FBS (P=0.013) and SBP (P=0.023). There was no significant relationship between vitamin D deficiency and metabolic syndrome. Due to the lack of relationship between vitamin D deficiency and metabolic syndrome, small number of participants in this study and very low case of normal vitamin D level, further studies are needed.

Poland syndrome was first described as a deficiency of the pectoral muscle with ipsilateral symbrachydactyly. Currently, numerous case reports describe variations of Poland syndrome in which pectoral muscle deficiency is often used as the only defining criterion. However, more syndromes can present with pectoral muscle deficiency. The aim of this review is to illustrate the diversity of the phenotypic spectrum of Poland syndrome and to create more awareness for alternative diagnoses in pectoral muscle deficiency. A systematic literature search was performed. Articles containing phenotypical descriptions of Poland syndrome were included. Data extraction included number of patients, sex, familial occurrence, and the definition of Poland syndrome used. In addition, hand deformities, thoracic deformities, and other deformities in each patient were recorded. Alternative syndrome diagnoses were identified in patients with a combination of hand, thorax, and other deformities. One hundred-and-thirty-six articles were included, describing 627 patients. Ten different definitions of Poland syndrome were utilized. In 58% of the cases, an upper extremity deformity was found and 43% of the cases had an associated deformity. Classic Poland syndrome was seen in 29%. Fifty-seven percent of the patients with a pectoral malformation, a hand malformation, and another deformity had at least 1feature that matched an alternative syndrome. Pectoral muscle hypoplasia is not distinctive for Poland syndrome alone but is also present in syndromes with other associated anomalies with a recognized genetic cause. Therefore, in patients with an atypical phenotype, we recommend considering other diagnoses and/or syndromes before diagnosing a patient with Poland syndrome. This can prevent diagnostic and prognostic errors. Differentiating Poland syndrome from the alternative diagnoses has serious consequences for the patient and their family in terms of inheritance and possible related anomalies

Chronic mucocutaneous candidiasis (CMC) is characterized by recurrent or persistent infections affecting the nails, skin and oral and genital mucosae caused by Candida spp., mainly Candida albicans. CMC is an infectious phenotype in patients with inherited or acquired T-cell deficiency. Patients with autosomal-dominant (AD) hyper IgE syndrome (HIES), AD signal transducer and activator of transcription 1 (STAT1) gain-of-function, autosomal-recessive (AR) deficiencies in interleukin (IL)-12 receptor β1 (IL-12Rβ1), IL-12p40, caspase recruitment domain-containing protein 9 (CARD9) or retinoic acid-related orphan receptor γT (RORγT) or AR autoimmune polyendocrinopathy–candidiasis–ectodermal dystrophy (APECED) develop CMC as a major infectious phenotype that is categorized as Syndromic CMC. In contrast, CMC disease (CMCD) is typically defined as CMC in patients in the absence of any other prominent clinical signs. This definition is not strict; thus, CMCD is currently used to refer to patients presenting with CMC as the main clinical phenotype. The etiology of CMCD is not related to genes that cause severe combined immunodeficiency or combined immunodeficiency, nor to genes responsible for Syndromic CMC. Four genetic etiologies, AR IL-17 receptor A, IL-17 receptor C and ACT1 deficiencies, and AD IL-17F deficiency, are reported to underlie CMCD. Each of these gene defects directly has an impact on IL-17 signaling, suggesting their nonredundant role in host mucosal immunity to Candida. Here, we review current knowledge focusing on IL-17 signaling and the genetic etiologies responsible for, and associated with, CMC. PMID:28090315

Acquired immunodeficiency syndrome (AIDS), caused by human immunodeficiency virus (HIV), has become, because of the rapid spread of the disease, a serious global problem and cannot be treated. Recent studies indicate that VIF is a protein of HIV to prevent all of human immunity to attack HIV. Molecular compounds of traditional Chinese medicine (TCM) database filtered through molecular docking and molecular dynamics simulations to inhibit VIF can protect against HIV. Glutamic acid, plantagoguanidinic acid, and Aurantiamide acetate based docking score higher with other TCM compounds selected. Molecular dynamics are useful for analysis and detection ligand interactions. According to the docking position, hydrophobic interactions, hydrogen bonding changes, and structure variation, the study try to select the efficacy of traditional Chinese medicine compound Aurantiamide acetate is better than the other for protein-ligand interactions to maintain the protein composition, based on changes in the structure.

We studied the immunological basis for the very potent encephalitogenicity of myelin/oligodendrocyte glycoprotein (MOG), a minor component of myelin in the CNS that is widely used to induce experimental autoimmune encephalomyelitis (EAE). For this purpose, we generated a mutant mouse lacking a functional mog gene. This MOG-deficient mouse presents no clinical or histological abnormalities, permitting us to directly assess the role of MOG as a target autoantigen in EAE. In contrast to WT mice, which developed severe EAE following immunization with whole myelin, MOG-deficient mice had a mild phenotype, demonstrating that the anti-MOG response is a major pathogenic component of the autoimmune response directed against myelin. Moreover, while MOG transcripts are expressed in lymphoid organs in minute amounts, both MOG-deficient and WT mice show similar T and B cell responses against the extracellular domain of MOG, including the immunodominant MOG 35–55 T cell epitope. Furthermore, no differences in the fine specificity of the T cell responses to overlapping peptides covering the complete mouse MOG sequence were observed between MOG+/+ and MOG–/– mice. In addition, upon adoptive transfer, MOG-specific T cells from WT mice and those from MOG-deficient mice are equally pathogenic. This total lack of immune tolerance to MOG in WT C57BL/6 mice may be responsible for the high pathogenicity of the anti-MOG immune response as well as the high susceptibility of most animal strains to MOG-induced EAE.

Changes that occur in the behaviour of voltage-gated ion channels and ligand-gated receptor channels due to gene mutations or auto-immune attack are the cause of channelopathies in the central and peripheral nervous system. Although the relation between molecular channel defects and clinical symptoms has been explained in the case of many neuromuscular channelopathies, the pathophysiology of auto-immunity in neuropsychiatric syndromes is still unclear. To review recent findings regarding neuronal auto-immune reactions in severe neuropsychiatric syndromes. Using PubMed, we consulted the literature published between 1990 and August 2014 relating to the occurrence of auto-immune antibodies in severe and persistent neuropsychiatric syndromes. Auto-antibodies have only limited access to the central nervous system, but if they do enter the system they can, in some cases, cause disease. We discuss recent findings regarding the occurrence of auto-antibodies against ligand-activated receptor channels and potassium channels in neuropsychiatric and neurological syndromes, including schizophrenia and limbic encephalitis. Although the occurrence of several auto-antibodies in schizophrenia has been confirmed, there is still no proof of a causal relationship in the syndrome. We still have no evidence of the prevalence of auto-immunity in neuropsychiatric syndromes. The discovery that an antibody against an ion channel is associated with some neuropsychiatric disorders may mean that in future it will be possible to treat patients by means of immunosuppression, which could lead to an improvement in a patient's cognitive abilities.

Colorectal carcinomas in patients with Lynch syndrome (LS) arise in a background of mismatch repair (MMR) deficiency, display a unique immune profile with upregulation of immune checkpoints, and response to immunotherapy. However, there is still a gap in understanding the pathogenesis of MMR-deficient colorectal premalignant lesions, which is essential for the development of novel preventive strategies for LS. To characterize the immune profile of premalignant lesions from a cohort of patients with LS. Whole-genome transcriptomic analysis using next-generation sequencing was performed in colorectal polyps and carcinomas of patients with LS. As comparator and model of MMR-proficient colorectal carcinogenesis, we used samples from patients with familial adenomatous polyposis (FAP). In addition, a total of 47 colorectal carcinomas (6 hypermutants and 41 nonhypermutants) were obtained from The Cancer Genome Atlas (TCGA) for comparisons. Samples were obtained from the University of Texas MD Anderson Cancer Center and "Regina Elena" National Cancer Institute, Rome, Italy. All diagnoses were confirmed by genetic testing. Polyps were collected at the time of endoscopic surveillance and tumors were collected at the time of surgical resection. The data were analyzed from October 2016 to November 2017. Assessment of the immune profile, mutational signature, mutational and neoantigen rate, and pathway enrichment analysis of neoantigens in LS premalignant lesions and their comparison with FAP premalignant lesions, LS carcinoma, and sporadic colorectal cancers from TCGA. The analysis was performed in a total of 28 polyps (26 tubular adenomas and 2 hyperplastic polyps) and 3 early-stage LS colorectal tumors from 24 patients (15 [62%] female; mean [SD] age, 48.12 [15.38] years) diagnosed with FAP (n = 10) and LS (n = 14). Overall, LS polyps presented with low mutational and neoantigen rates but displayed a striking immune activation profile characterized by CD4 T cells

Diagnosis and treatment of chronic acquired demyelinating polyneuropathies.

PubMed

Latov, Norman

2014-08-01

Chronic neuropathies are operationally classified as primarily demyelinating or axonal, on the basis of electrodiagnostic or pathological criteria. Demyelinating neuropathies are further classified as hereditary or acquired-this distinction is important, because the acquired neuropathies are immune-mediated and, thus, amenable to treatment. The acquired chronic demyelinating neuropathies include chronic inflammatory demyelinating polyneuropathy (CIDP), neuropathy associated with monoclonal IgM antibodies to myelin-associated glycoprotein (MAG; anti-MAG neuropathy), multifocal motor neuropathy (MMN), and POEMS syndrome. They have characteristic--though overlapping--clinical presentations, are mediated by distinct immune mechanisms, and respond to different therapies. CIDP is the default diagnosis if the neuropathy is demyelinating and no other cause is found. Anti-MAG neuropathy is diagnosed on the basis of the presence of anti-MAG antibodies, MMN is characterized by multifocal weakness and motor conduction blocks, and POEMS syndrome is associated with IgG or IgA λ-type monoclonal gammopathy and osteosclerotic myeloma. The correct diagnosis, however, can be difficult to make in patients with atypical or overlapping presentations, or nondefinitive laboratory studies. First-line treatments include intravenous immunoglobulin (IVIg), corticosteroids or plasmapheresis for CIDP; IVIg for MMN; rituximab for anti-MAG neuropathy; and irradiation or chemotherapy for POEMS syndrome. A correct diagnosis is required for choosing the appropriate treatment, with the aim of preventing progressive neuropathy.

Given the challenges in exploring lifelong therapy with little side effect for human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) cases, there is increasing interest in developing traditional Chinese medicine (TCM) treatments based on specific TCM syndrome. However, there are few objective and biological evidences for classification and diagnosis of HIV/AIDS TCM syndromes to date. In this study, iTRAQ-2DLC-MS/MS coupled with bioinformatics were firstly employed for comparative proteomic profiling of top popular TCM syndromes of HIV/AIDS: accumulation of heat-toxicity (AHT) and Yang deficiency of spleen and kidney (YDSK). It was found that for the two TCM syndromes, the identified differential expressed proteins (DEPs) as well as their biological function distributions and participation in signaling pathways were significantly different, providing biological evidence for the classification of HIV/AIDS TCM syndromes. Furthermore, the TCM syndrome-specific DEPs were confirmed as biomarkers based on western blot analyses, including FN1, GPX3, KRT10 for AHT and RBP4, ApoE, KNG1 for YDSK. These biomarkers also biologically linked with the specific TCM syndrome closely. Thus the clinical and biological basis for differentiation and diagnosis of HIV/AIDs TCM syndromes were provided for the first time, providing more opportunities for stable exertion and better application of TCM efficacy and superiority in HIV/AIDS treatment.

Abstract Objectives To explore the relationships between traditional Chinese medicine (TCM) syndromes and disease severity and prognoses after ischemic stroke, such as neurologic deficits and decline in activities of daily living (ADLs). Methods The study included 211 patients who met the inclusion criteria of acute ischemic stroke based on clinical manifestations, computed tomography or magnetic resonance imaging findings, and onset of ischemic stroke within 72 hours with clear consciousness. To assess neurologic function and ADLs in patients with different TCM syndromes, the TCM Syndrome Differentiation Diagnostic Criteria for Apoplexy scale (containing assessments of wind, phlegm, blood stasis, fire-heat, qi deficiency, and yin deficiency with yang hyperactivity syndromes) was used within 72 hours of stroke onset, and Western medicine–based National Institutes of Health Stroke Scale (NIHSS) and Barthel Index (BI) assessments were performed at both admission and discharge. Results The most frequent TCM syndromes associated with acute ischemic stroke were wind syndrome, phlegm syndrome, and blood stasis syndrome. Improvement according to the BI at discharge and days of admission were significantly different between patients with and those without fire-heat syndrome. Patients with qi deficiency syndrome had longer hospital stays and worse NIHSS and BI assessments at discharge than patients without qi deficiency syndrome. All the reported differences reached statistical significance. Conclusions These results provide evidence that fire-heat syndrome and qi deficiency syndrome are essential elements that can predict short-term prognosis of acute ischemic stroke. PMID:23600945

Disorders of the auditory and vestibular system are often associated with human immunodeficiency virus infection and acquired immunodeficiency syndrome. However, the extent and nature of these vestibular manifestations are unclear. To systematically review the current peer-reviewed literature on vestibular manifestations and pathology related to human immunodeficiency virus and acquired immunodeficiency syndrome. Systematic review of peer-reviewed articles related to vestibular findings in individuals with human immunodeficiency virus infection and acquired immunodeficiency syndrome. Several electronic databases were searched. We identified 442 records, reduced to 210 after excluding duplicates and reviews. These were reviewed for relevance to the scope of the study. We identified only 13 reports investigating vestibular functioning and pathology in individuals affected by human immunodeficiency virus and acquired immunodeficiency syndrome. This condition can affect both the peripheral and central vestibular system, irrespective of age and viral disease stage. Peripheral vestibular involvement may affect up to 50 per cent of patients, and central vestibular involvement may be even more prevalent. Post-mortem studies suggest direct involvement of the entire vestibular system, while opportunistic infections such as oto- and neurosyphilis and encephalitis cause secondary vestibular dysfunction resulting in vertigo, dizziness and imbalance. Patients with human immunodeficiency virus and acquired immunodeficiency syndrome should routinely be monitored for vestibular involvement, to minimise functional limitations of quality of life.

Hyponatremia is often observed in patients with Legionella pneumonia. However, other electrolyte abnormalities are uncommon and the mechanism remains to be clarified. We experienced two male cases of acquired Fanconi syndrome associated with Legionella pneumonia. The laboratory findings at admission showed hypophosphatemia, hypokalemia, hypouricemia and/or hyponatremia. In addition, they had the generalized dysfunction of the renal proximal tubules presenting decreased tubular reabsorption of phosphate (%TRP), increased fractional excretion of potassium (FEK) and uric acid (FEUA), low-molecular-weight proteinuria, panaminoaciduria and glycosuria. Therefore, they were diagnosed as Fanconi syndrome. Treatment for Legionella pneumonia with antibiotics resulted in the improvement of all serum electrolyte abnormalities and normalization of the %TRP, FEK, FEUA, low-molecular-weight proteinuria, panaminoaciduria and glycosuria, suggesting that Legionella pneumophila infection contributed to the pathophysiology of Fanconi syndrome. To the best of our knowledge, this is the first report demonstrating Fanconi syndrome associated with Legionella pneumonia.

Illicium verum, whose extractives can activate the demic acquired immune response, is an expensive medicinal plant. However, the rich extractives in I. verum biomass were seriously wasted for the inefficient extraction and separation processes. In order to further utilize the biomedical resources for the good acquired immune response, the four extractives were obtained by SJYB extraction, and then the immunology moleculars of SJYB extractives were identified and analyzed by GC–MS. The result showed that the first-stage extractives contained 108 components including anethole (40.27%), 4-methoxy-benzaldehyde (4.25%), etc.; the second-stage extractives had 5 components including anethole (84.82%), 2-hydroxy-2-(4-methoxy-phenyl)-n-methyl-acetamide (7.11%), etc.; the third-stage extractives contained one component namely anethole (100%); and the fourth-stage extractives contained 5 components including cyclohexyl-benzene (64.64%), 1-(1-methylethenyl)-3-(1-methylethyl)-benzene (17.17%), etc. The SJYB extractives of I. verum biomass had a main retention time between 10 and 20 min what’s more, the SJYB extractives contained many biomedical moleculars, such as anethole, eucalyptol, [1S-(1α,4aα,10aβ)]-1,2,3,4,4a,9,10,10a-octahydro-1,4a-dimethyl-7-(1-methylethyl)-1-phenanthrenecarboxylic acid, stigmast-4-en-3-one, γ-sitosterol, and so on. So the functional analytical results suggested that the SJYB extractives of I. verum had a function in activating the acquired immune response and a huge potential in biomedicine. PMID:27081359

To study the effect of primary Epstein-Barr virus (EBV) infection on antigen-specific antibody production, we immunized 17 college students who had developed acute infectious mononucleosis with the T-cell dependent neoantigen bacteriophage phi X174. During the early phase of infectious mononucleosis, the proportion of peripheral blood lymphocytes displaying Ia and T8 (CD8) phenotypes was increased and the T helper/suppressor (T4/T8) ratio was decreased (less than 1). These abnormalities disappeared during the convalescent phase. Correlating with EBV-induced changes in T lymphocytes, we demonstrated depressed humoral immune responses to bacteriophage phi X174 both in vivo and in vitro. In vitro coculture experiments indicated that the Ia+ suppressor T cells could inhibit antibody production and isotype switch. Removal of T8+ lymphocytes from patient T cells normalized in vitro antibody synthesis. In addition, impaired B-cell function was shown to be in part responsible for deficient antibody production. These studies demonstrate that infection with EBV affects both B and T lymphocytes and causes a broad-based transient immune deficiency in patients with uncomplicated infectious mononucleosis.

The development of acquired immunity to tapeworms and progress towards active immunization, with special reference to Echinococcus spp

An assessment is made of the present state of knowledge on acquired immune responses developed by the intermediate and definitive hosts to tapeworm infections. From this evaluation, some gaps in knowledge and some of the problems associated with the development of practical immunization techniques are described. The principal conclusion reached is that absolute resistance to the larval stage can be acquired and resistance to a number of cestode species can be artificially induced in a number of hosts. Thus, research directed towards isolation and characterization of the functional antigens may lead to the development of vaccines for use in public health programmes, such as for the control of echinococcosis, as well as for improving the present status of meat hygiene in regions where cysticercosis, for example, exists.

Crusted scabies-associated immune reconstitution inflammatory syndrome

PubMed Central

2012-01-01

Background Despite the widely accepted association between crusted scabies and human immunodeficiency virus (HIV)-infection, crusted scabies has not been included in the spectrum of infections associated with immune reconstitution inflammatory syndrome in HIV-infected patients initiating antiretroviral therapy. Case presentation We report a case of a 28-year-old Mexican individual with late HIV-infection, who had no apparent skin lesions but soon after initiation of antiretroviral therapy, he developed an aggressive form of crusted scabies with rapid progression of lesions. Severe infestation by Sarcoptes scabiei was confirmed by microscopic examination of the scale and skin biopsy. Due to the atypical presentation of scabies in a patient responding to antiretroviral therapy, preceded by no apparent skin lesions at initiation of antiretroviral therapy, the episode was interpreted for the first time as “unmasking crusted scabies-associated immune reconstitution inflammatory syndrome”. Conclusion This case illustrates that when crusted scabies is observed in HIV-infected patients responding to antiretroviral therapy, it might as well be considered as a possible manifestation of immune reconstitution inflammatory syndrome. Patient context should be considered for adequate diagnosis and treatment of conditions exacerbated by antiretroviral therapy-induced immune reconstitution. PMID:23181485

Staphylococcal toxic shock syndrome: superantigen-mediated enhancement of endotoxin shock and adaptive immune suppression.

Infectious diseases caused by Staphylococcus aureus present a significant clinical and public health problem. S. aureus causes some of the most severe hospital-associated and community-acquired illnesses. Specifically, it is the leading cause of infective endocarditis and osteomyelitis, and the second leading cause of sepsis in the USA. While pathogenesis of S. aureus infections is at the center of current research, many questions remain about the mechanisms underlying staphylococcal toxic shock syndrome (TSS) and associated adaptive immune suppression. Both conditions are mediated by staphylococcal superantigens (SAgs)-secreted staphylococcal toxins that are major S. aureus virulence factors. Toxic shock syndrome toxin-1 (TSST-1) is the SAg responsible for almost all menstrual TSS cases in the USA. TSST-1, staphylococcal enterotoxin B and C are also responsible for most cases of non-menstrual TSS. While SAgs mediate all of the hallmark features of TSS, such as fever, rash, hypotension, and multi-organ dysfunction, they are also capable of enhancing the toxic effects of endogenous endotoxin. This interaction appears to be critical in mediating the severity of TSS and related mortality. In addition, interaction between SAgs and the host immune system has been recognized to result in a unique form of adaptive immune suppression, contributing to poor outcomes of S. aureus infections. Utilizing rabbit models of S. aureus infective endocarditis, pneumonia and sepsis, and molecular genetics techniques, we aim to elucidate the mechanisms of SAg and endotoxin synergism in the pathogenesis of TSS, and examine the cellular and molecular mechanisms underlying SAg-mediated immune dysfunction.

Growth hormone deficiency affects roughly between one in 3000 and one in 4000 children with most instances of growth hormone deficiency being idiopathic. Growth hormone deficiency can also be associated with genetic diseases or chromosome abnormalities. Association of growth hormone deficiency together with hypothalamic-pituitary axis malformation and Cat-Eye syndrome is a very rare condition. We report a family with two brothers presenting with growth delay due to a growth hormone deficiency associated with a polymalformation syndrome. They both displayed pre-auricular pits and tags, imperforate anus and Duane retraction syndrome. Both parents and a third unaffected son displayed normal growth pattern. Cerebral MRI showed a hypothalamic-pituitary axis malformation in the two affected brothers. Cytogenetic studies revealed a type I small supernumerary marker chromosome derived from chromosome 22 resulting in a tetrasomy 22pter-22q11.21 characteristic of the Cat-Eye syndrome. The small supernumerary marker chromosome was present in the two affected sons and the mother in a mosaic state. Patients with short stature due to growth hormone deficiency should be evaluated for chromosomal abnormality. Family study should not be underestimated. Copyright © 2015 Elsevier Masson SAS.

Human immunodeficiency virus (HIV) infection is a major health burden across the world which leads to the development of acquired immune deficiency syndrome (AIDS). This review article discusses the prevalence of HIV, its major routes of transmission, natural immunity, and evasion from the host immune system. HIV is mostly prevalent in Sub-Saharan Africa and low income countries. It is mostly transmitted by sharing syringe needles, blood transfusion, and sexual routes. The host immune system is categorized into three main types; the innate, the adaptive, and the intrinsic immune system. Regarding the innate immune system against HIV, the key players are mucosal membrane, dendritic cells (DCs), complement system, interferon, and host Micro RNAs. The major components of the adaptive immune system exploited by HIV are T cells mainly CD4+ T cells and B cells. The intrinsic immune system confronted by HIV involves (apolipoprotein B mRNA-editing enzyme, catalytic polypeptide-like 3G) APOBEC3G, tripartite motif 5-α (TRIM5a), terherin, and (SAM-domain HD-domain containing protein) SAMHD1. HIV-1 efficiently interacts with the host immune system, exploits the host machinery, successfully replicates and transmits from one cell to another. Further research is required to explore evasion strategies of HIV to develop novel therapeutic approaches against HIV. © 2016 APMIS. Published by John Wiley & Sons Ltd.

Prediction of selenoprotein T structure and its response to selenium deficiency in chicken immune organs.

Selenoprotein T (SelT) is associated with the regulation of calcium homeostasis and neuroendocrine secretion. SelT can also change cell adhesion and is involved in redox regulation and cell fixation. However, the structure and function of chicken SelT and its response to selenium (Se) remains unclear. In the present study, 150 1-day-old chickens were randomly divided into a low Se group (L group, fed a Se-deficient diet containing 0.020 mg/kg Se) and a control group (C group, fed a diet containing sodium selenite at 0.2 mg/kg Se). The immune organs (spleen, thymus, and bursa of Fabricius) were collected at 15, 25, 35, 45, and 55 days of age. We performed a sequence analysis and predicted the structure and function of SelT. We also investigated the effects of Se deficiency on the expression of SelT, selenophosphate synthetase-1 (SPS1), and selenocysteine synthase (SecS) using RT-PCR and the oxidative stress in the chicken immune organs. The data showed that the coding sequence (CDS) and deduced amino acid sequence of SelT were highly similar to those of 17 other animals. Se deficiency induced lower (P < 0.05) levels of SelT, SPS1, and SecS, reduced the catalase (CAT) activity, and increased the levels of hydrogen peroxide (H2O2) and hydroxyl radical (-OH) in immune organs. In conclusion, the CDS and deduced amino acid sequence of chicken SelT are highly homologous to those of various mammals. The redox function and response to the Se deficiency of chicken SelT may be conserved. A Se-deficient diet led to a decrease in SelT, SecS, and SPS1 and induced oxidative stress in the chicken immune organs. To our knowledge, this is the first report of predictions of chicken SelT structure and function. The present study demonstrated the relationship between the selenoprotein synthases (SPS1, SecS) and SelT expression in the chicken immune organs and further confirmed oxidative stress caused by Se deficiency. Thus, the information presented in this study is helpful to

Impaired local immune response in vitamin A-deficient rats.

The functional integrity of the local immune system in vitamin A-deficient (A-) rats was investigated. Secretory IgA levels in the intestinal fluid of A- rats were significantly lower than in controls. This and the decrease in intensity of immunofluorescent staining for secretory component (SC) in the intestinal cells was related to the duration of vitamin A deprivation. IgG levels in the intestinal fluid, and serum IgA and IgG levels were unaffected in deficiency. Moreover, when the response of animals to DNP50-BGG was evaluated, the local anti-DNP response in the intestine was markedly depressed. These defects may result from impaired synthesis of SC by epithelial cells. On the other hand, the serum antibody response in deficient animals was not noticeably different from that of the controls; if any, htere was a slight reduction in the affinity of antibody.

Acquired immune deficiency syndrome (AIDS) is a recently recognized entity characterized by a deficiency in cell mediated immune response. The syndrome is manifested by the development of otherwise rare malignant neoplasms and severe life-threatening opportunistic infections. Case histories of five AIDS patients evaluated for abdominal pain are presented to demonstrate the unusual spectrum of intra-abdominal pathology that may be encountered in the AIDS patient. As the number of patients with AIDS continues to escalate, surgical evaluation and intervention will be required more frequently. An understanding of this syndrome and its complications is mandatory for the surgeon to adequately evaluate AIDS patients with abdominal pain. PMID:6322708

Immune reconstitution inflammation syndrome typically occurs within days after patients undergo highly active anti-retroviral therapy and is a big hurdle for effective treatment of AIDS patients. In this study, we monitored immune reconstitution inflammation syndrome occurrence in 238 AIDS patients treated with highly active anti-retroviral therapy. Among them, immune reconstitution inflammation syndrome occurred in 47 cases (19.7%). Immune reconstitution inflammation syndrome patients had significantly higher rate of opportunistic infection (p<0.001) and persistently lower CD4(+) cell count (p<0.001) compared to the non-immune reconstitution inflammation syndrome patients. In contrast, no significant differences in HIV RNA loads were observed between the immune reconstitution inflammation syndrome group and non-immune reconstitution inflammation syndrome group. These data suggest that a history of opportunistic infection and CD4(+) cell counts at baseline may function as risk factors for immune reconstitution inflammation syndrome occurrence in AIDS patients as well as potential prognostic markers. These findings will improve the management of AIDS with highly active anti-retroviral therapy. Copyright © 2013 Elsevier Editora Ltda. All rights reserved.

The adhesive cell surface molecule P(0) is the most abundant glycoprotein in peripheral nerve myelin and fulfills pivotal functions during myelin formation and maintenance. Mutations in the corresponding gene cause hereditary demyelinating neuropathies. In mice heterozygously deficient in P(0) (P(0)(+/-) mice), an established animal model for a subtype of hereditary neuropathies, T-lymphocytes are present in the demyelinating nerves. To monitor the possible involvement of the immune system in myelin pathology, we cross-bred P(0)(+/-) mice with null mutants for the recombination activating gene 1 (RAG-1) or with mice deficient in the T-cell receptor alpha-subunit. We found that in P(0)(+/-) mice myelin degeneration and impairment of nerve conduction properties is less severe when the immune system is deficient. Moreover, isolated T-lymphocytes from P(0)(+/-) mice show enhanced reactivity to myelin components of the peripheral nerve, such as P(0), P(2), and myelin basic protein. We hypothesize that autoreactive immune cells can significantly foster the demyelinating phenotype of mice with a primarily genetically based peripheral neuropathy.

Objective Bruton’s Tyrosine Kinase (BTK) is a B cell signaling protein that also contributes to innate immunity. BTK-inhibitors prevent autoimmune arthritis, but have off-target effects, and the mechanisms of protection remain unknown. These studies used genetic deletion to investigate the role of BTK in adaptive and innate immune responses that drive inflammatory arthritis. Methods Btk-deficient K/BxN mice were generated to study the role of BTK in a spontaneous model that requires both adaptive and innate immunity. The K/BxN serum transfer model was used to bypass the adaptive system and elucidate the role of BTK in innate immune contributions to arthritis. Results Btk-deficiency conferred disease protection to K/BxN mice, confirming BTK-inhibitor outcomes. B lymphocytes were profoundly reduced, more than in other Btk-deficient models. Subset analysis revealed loss at all developmental stages. Germinal center B cells were also decreased, with downstream effects on T follicular helper numbers, and greatly reduced autoantibodies. In contrast, total IgG was only mildly decreased. Strikingly, and in contrast to small molecule inhibitors, Btk-deficiency had no effect on the serum transfer model of arthritis. Conclusions BTK contributes to autoimmune arthritis primarily via its role in B cell signaling, not innate immune components. PMID:26945549

Cornelia de Lange syndrome is a genetic disease characterized by distinctive facial features, failure to thrive, microcephaly and several malformations associated. Its main endocrinological features are anomalies of the genitalia. We present a 13-year-old boy, who suffered from complicated aspiration pneumonia and showed Cornelia de Lange syndrome phenotype, with global developmental delay, suction-swallowing abnormalities, short stature and abnormal genitalia associated. His bone age was delayed, so he underwent full endocrinological panel. Central hypothyroidism, growth hormone deficiency and low luteinizing hormone-follicle-stimulating hormone levels were observed and multiple pituitary hormone deficiencies diagnosis was made. Basal cortisol, adrenocorticotropic hormone and prolactin levels were normal. He received thyroid hormonal substitution. Multiple pituitary hormone deficiencies are an unusual feature of De Lange syndrome. We suggest evaluating all different endocrine axes in these patients. Sociedad Argentina de Pediatría.

Interleukin-1 and cutaneous inflammation: a crucial link between innate and acquired immunity.

PubMed

Murphy, J E; Robert, C; Kupper, T S

As our primary interface with the environment, the skin is constantly subjected to injury and invasion by pathogens. The fundamental force driving the evolution of the immune system has been the need to protect the host against overwhelming infection. The ability of T and B cells to recombine antigen receptor genes during development provides an efficient, flexible, and powerful immune system with nearly unlimited specificity for antigen. The capacity to expand subsets of antigen-specific lymphocytes that become activated by environmental antigens (memory response) is termed "acquired" immunity. Immunologic memory, although a fundamental aspect of mammalian biology, is a relatively recent evolutionary event that permits organisms to live for years to decades. "Innate" immunity, mediated by genes that remain in germ line conformation and encode for proteins that recognize conserved structural patterns on microorganisms, is a much more ancient system of host defense. Defensins and other antimicrobial peptides, complement and opsonins, and endocytic receptors are all considered components of the innate immune system. None of these, however, are signal-transducing receptors. Most recently, a large family of cell surface receptors that mediate signaling through the NF-kappaB transcription factor has been identified. This family of proteins shares striking homology with plant and Drosophila genes that mediate innate immunity. In mammals, this family includes the type I interleukin-1 receptor, the interleukin-18 receptor, and a growing family of Toll-like receptors, two of which were recently identified as signal-transducing receptors for bacterial endotoxin. In this review, we discuss how interleukin-1 links the innate and acquired immune systems to provide synergistic host defense activities in skin.

To evaluate the rates of new-onset cytomegalovirus (CMV) retinitis and worsening existing CMV retinitis in patients with AIDS after initiating combination antiretroviral therapy (cART) and the role of an immune recovery inflammatory syndrome (IRIS). Cohort study. Immune recovery was defined as an increase in CD4 + T cells to ≥100 cells/μL; rates of new-onset CMV retinitis and of worsening of CMV retinitis (either increasing border activity or retinitis progression) were compared between those with and without immune recovery. Among patients without CMV retinitis, 1 of 75 patients with immune recovery developed CMV retinitis in the first 6 months after initiating cART vs 1 of 31 without immune recovery (P = .14). Among patients with CMV retinitis, the rates of retinitis progression and increasing retinitis border activity among patients during the first 6 months after initiating cART in those with immune recovery were 0.11 per person-year (PY; 95% confidence interval [CI] 0-0.62) and 0.11 per PY (95% CI 0-0.62), respectively, vs 0.67 per PY (95% CI 0.22-1.56) and 0.40 per PY (95% CI 0.08-1.17), respectively, for those without immune recovery (P = .11 and .47). Among persons with AIDS who experience immune recovery, there was neither an increased rate of new-onset CMV retinitis nor worsening of existing CMV retinitis in the first 6 months after initiating cART vs those without immune recovery. These data are consistent with the known 3- to 6-month lag in recovery of specific immunity to CMV after initiating cART and suggest that "immune recovery retinitis," a proposed immune recovery inflammatory syndrome phenomenon, is rare.

Vitamin D modulates innate and adaptive immune responses, and vitamin D deficiency is associated with increased mortality in hospitalized patients with pneumonia. We evaluated the prevalence of vitamin D deficiency in Korean patients with acute respiratory distress syndrome (ARDS) and its effect on the clinical outcomes of ARDS. We retrospectively analyzed the data of 108 patients who had a measured serum level of 25-hydroxy vitamin D3 (25(OH)D3) at the time of diagnosis with ARDS. The clinical outcomes were evaluated based on 25(OH)D3 levels of 20 ng/mL and stratified by quartiles of 25(OH)D3 levels. The mean age of patients was 59.4 years old; 77 (71.3%) were male. Vitamin D deficiency was found in 103 patients (95.4%). The mean 25(OH)D3 level was 8.3 ± 7.0 ng/mL. Neither in-hospital mortality (40.0% vs. 68.0%) nor 6-month mortality (40.0% vs. 71.8%) significantly differed between groups. There were no significant differences in 25(OH)D3 level between survivors (8.1 ± 7.6 ng/mL) and non-survivors (8.5 ± 6.8 ng/mL, p = 0.765). There were no trends toward a difference in mortality among quartiles of 25(OH)D3 levels. However, 25(OH)D3 levels were inversely related with length of hospital stay and intensive care unit stay among in-hospital survivors. Vitamin D deficiency was prevalent in Korean patients with ARDS. However, levels of vitamin D were not associated with mortality. A large, prospective study is needed to evaluate the effects of vitamin D deficiency on clinical outcomes of ARDS.

1983-01-01

Acquired immunodeficiency syndrome, or AIDS, is a new illness that occurs in previously healthy individuals. It is characterized by immunodeficiency, opportunistic infections and unusual malignant diseases. Life-threatening single or multiple infections with viruses, mycobacteria, fungi or protozoa are common. A rare neoplasm, Kaposi's sarcoma, has developed in approximately one third of patients with AIDS. More than 800 cases of AIDS have been reported in North America, over 24 of them in Canada. The majority of patients are male homosexuals, although AIDS has also developed in abusers of intravenously administered drugs, Haitian immigrants, individuals with hemophilia, recipients of blood transfusions, prostitutes, and infants, spouses and partners of patients with AIDS. The cause of AIDS is unknown, but the features are consistent with an infectious process. Early diagnosis can be difficult owing to the nonspecific symptoms and signs of the infections and malignant diseases. Therefore, vigilance by physicians is of utmost importance. PMID:6342737

How We Manage Adenosine Deaminase-Deficient Severe Combined Immune Deficiency (ADA SCID).

PubMed

Kohn, Donald B; Gaspar, H Bobby

2017-05-01

Adenosine deaminase-deficient severe combined immune deficiency (ADA SCID) accounts for 10-15% of cases of human SCID. From what was once a uniformly fatal disease, the prognosis for infants with ADA SCID has improved greatly based on the development of multiple therapeutic options, coupled with more frequent early diagnosis due to implementation of newborn screening for SCID. We review the various treatment approaches for ADA SCID including allogeneic hematopoietic stem cell transplantation (HSCT) from a human leukocyte antigen-matched sibling or family member or from a matched unrelated donor or a haplo-identical donor, autologous HSCT with gene correction of the hematopoietic stem cells (gene therapy-GT), and enzyme replacement therapy (ERT) with polyethylene glycol-conjugated adenosine deaminase. Based on growing evidence of safety and efficacy from GT, we propose a treatment algorithm for patients with ADA SCID that recommends HSCT from a matched family donor, when available, as a first choice, followed by GT as the next option, with allogeneic HSCT from an unrelated or haplo-identical donor or long-term ERT as other options.

Watkins, Richard R; Lemonovich, Tracy L; Salata, Robert A

2015-05-01

Vitamin D plays an important role in modulating the immune response to infections. Deficiency of vitamin D is a common condition, affecting both the general population and patients in health care facilities. Over the last decade, an increasing body of evidence has shown an association between vitamin D deficiency and an increased risk for acquiring several infectious diseases, as well as poorer outcomes in vitamin D deficient patients with infections. This review details recent developments in understanding the role of vitamin D in immunity, the antibacterial actions of vitamin D, the association between vitamin D deficiency and common infections (like sepsis, pneumonia, influenza, methicillin-resistant Staphylococcus aureus, human immunodeficiency virus type-1 (HIV), and hepatitis C virus (HCV)), potential therapeutic implications for vitamin D replacement, and future research directions.

2009-12-01

To report a successfully treated case of acquired night blindness associated with fundus white spots secondary to vitamin A deficiency. An ocular examination, electrophysiologic testing, as well as visual field and OCT examinations were obtained on a 61-year-old man with vitamin A deficiency who had previously undergone gastric bypass surgery. The patient had a re-evaluation after treatment with high doses of oral vitamin A. The patient was observed to have numerous white spots in the retina of each eye. Best-corrected visual acuity was initially 20/80 in each eye, which improved to 20/40-1 OU after oral vitamin A therapy for 2 months. Full field electroretinogram (ERG) testing, showed non-detectable rod function and a 34 and 41% reduction for 32-Hz flicker and single flash cone responses, respectively, below the lower limits of normal. Both rod and cone functions markedly improved after initiation of vitamin A therapy. Vitamin A deficiency needs to be considered in a patient with white spots of the retina in the presence of poor night vision.

Góth, László; Bigler, N William

2007-09-01

Patients with low (inherited and acquired) catalase activities who are treated with infusion of uric acid oxidase because they are at risk of tumour lysis syndrome may experience very high concentrations of hydrogen peroxide. They may suffer from methemoglobinaemia and haemolytic anaemia which may be attributed either to deficiency of glucose-6-phosphate dehydrogenase or to other unknown circumstances. Data have not been reported from catalase deficient patients who were treated with uric acid oxidase. It may be hypothesized that their decreased blood catalase could lead to the increased concentration of hydrogen peroxide which may cause haemolysis and formation of methemoglobin. Blood catalase activity should be measured for patients at risk of tumour lysis syndrome prior to uric acid oxidase treatment.

The immunocompromised district in dermatology: A unifying pathogenic view of the regional immune dysregulation.

2014-01-01

Besides the systemic immune deficiency, a sectorial default in immune control may occur in immunocompetent subjects. This regional immune defect can appear and remain confined to differently damaged skin areas, lately labeled immunocompromised districts (ICDs). An ICD is a skin area more vulnerable than the rest of the body for genetic or acquired reasons. Its vulnerability mainly consists in a local dysregulation of the immune control, which often facilitates (but sometimes hinders) the local onset of immunity-related eruptions or skin disorders. The factors responsible for localized immune dysregulation are multifarious, being represented by chronic lymphatic stasis, herpetic infections, ionizing or ultraviolet (UV) radiations, burns, all sorts of trauma (especially amputation), tattooing, intradermal vaccinations, and others of disparate nature (eg, paralytic stroke, poliomyelitis). Whatever the cause, in time an ICD may become a vulnerable site, prone to developing opportunistic infections, tumors, or dysimmune reactions (often of granulomatous type), strictly confined to the district itself; however, the opposite may also occur with systemic immune disorders or malignancies that selectively spare the district. In any case, the immunologic behavior of an ICD is different from that of the rest of the body. The pathomechanisms involved in this sectorial immune destabilization may reside in locally hampered lymph drainage that hinders the normal trafficking of immunocompetent cells (eg, chronic lymphedema, posttraumatic lymph stasis) or in a damage to sensory nerve fibers that release immunity-related peptides (eg, herpetic infections, carpal tunnel syndrome), or in both conditions (eg, amputation stump, radiation dermatitis). The ICD is a conceptual entity with no definite shape or dimension. It may take an extremely variable form and extent depending on the causative agent, ranging from a minimal area (eg, intradermal vaccination) or a small area (eg, herpes

The so-called «testosterone deficiency syndrome» is a blend of nonspecific symptoms typical of the physiological process of aging. This syndrome has been the subject of intense promotional activity that has presented the phenomenon as highly prevalent and with a major public health impact. This strategy has been accompanied by the emergence of new and easy to administer testosterone devices into the pharmaceutical market and has generated significant sales for drug companies. The commercial promotion of testosterone deficiency syndrome and its remedies has exploited cultural stereotypes of aging and sexuality through awareness campaigns promoted by the laboratories involved and has been disseminated by media with the participation of numerous experts and with the support of scientific associations, representing a paradigmatic case of disease mongering. This example might be of use in the response to disease mongering activities from the clinical and public health fields. Copyright © 2013 SESPAS. Published by Elsevier Espana. All rights reserved.

Bruton's tyrosine kinase (BTK) is a B cell signaling protein that also contributes to innate immunity. BTK inhibitors prevent autoimmune arthritis but have off-target effects, and the mechanisms of protection remain unknown. We undertook these studies using genetic deletion to investigate the role of BTK in adaptive and innate immune responses that drive inflammatory arthritis. BTK-deficient K/BxN mice were generated to study the role of BTK in a spontaneous model that requires both adaptive and innate immunity. The K/BxN serum-transfer model was used to bypass the adaptive system and elucidate the role of BTK in innate immune contributions to arthritis. BTK deficiency conferred disease protection to K/BxN mice, confirming outcomes of BTK inhibitors. B lymphocytes were profoundly reduced, more than in other models of BTK deficiency. Subset analysis revealed loss of B cells at all developmental stages. Germinal center B cells were also decreased, with downstream effects on numbers of follicular helper T cells and greatly reduced autoantibodies. In contrast, total IgG was only mildly decreased. Strikingly, and in contrast to small molecule inhibitors, BTK deficiency had no effect in the serum-transfer model of arthritis. BTK contributes to autoimmune arthritis primarily through its role in B cell signaling and not through innate immune components. © 2016, American College of Rheumatology.

NAD(P)H: Quinone Oxidoreductase 1 Deficiency Conjoint with Marginal Vitamin C Deficiency Causes Cigarette Smoke Induced Myelodysplastic Syndromes

PubMed Central

Das, Archita; Dey, Neekkan; Ghosh, Arunava; Das, Tanusree; Chatterjee, Indu B.

2011-01-01

Background The etiology of myelodysplastic syndromes (MDS) is largely unknown. Exposure to cigarette smoke (CS) is reported to be associated with MDS risk. There is inconsistent evidence that deficiency of NAD(P)H-quinone: oxidoreductase 1 (NQO1) increases the risk of MDS. Earlier we had shown that CS induces toxicity only in marginal vitamin C-deficient guinea pigs but not in vitamin C-sufficient ones. We therefore considered that NQO1 deficiency along with marginal vitamin C deficiency might produce MDS in CS-exposed guinea pigs. Methodology and Principal Findings Here we show that CS exposure for 21 days produces MDS in guinea pigs having deficiency of NQO1 (fed 3 mg dicoumarol/day) conjoint with marginal vitamin C deficiency (fed 0.5 mg vitamin C/day). As evidenced by morphology, histology and cytogenetics, MDS produced in the guinea pigs falls in the category of refractory cytopenia with unilineage dysplasia (RCUD): refractory anemia; refractory thrombocytopenia that is associated with ring sideroblasts, micromegakaryocytes, myeloid hyperplasia and aneuploidy. MDS is accompanied by increased CD34(+) cells and oxidative stress as shown by the formation of protein carbonyls and 8-oxodeoxyguanosine. Apoptosis precedes MDS but disappears later with marked decrease in the p53 protein. MDS produced in the guinea pigs are irreversible. MDS and all the aforesaid pathophysiological events do not occur in vitamin C-sufficient guinea pigs. However, after the onset of MDS vitamin C becomes ineffective. Conclusions and Significance CS exposure causes MDS in guinea pigs having deficiency of NQO1 conjoint with marginal vitamin C deficiency. The syndromes are not produced in singular deficiency of NQO1 or marginal vitamin C deficiency. Our results suggest that human smokers having NQO1 deficiency combined with marginal vitamin C deficiency are likely to be at high risk for developing MDS and that intake of a moderately large dose of vitamin C would prevent MDS.

Here, we report a case of trichuris dysentery syndrome complicated with severe chronic iron deficiency anaemia in a 4-year-old girl who required blood transfusion. The nematode was visualized on stool microscopic and colonoscopic examination. A longer duration of anti-helminthic treatment is required to achieve effective and better outcome.

Immune Reconstitution Inflammatory Syndrome (IRIS): What pathologists should know.

PubMed

Nelson, Ann Marie; Manabe, Yukari C; Lucas, Sebastian B

2017-07-01

Antiretroviral therapy has significantly improved the quality and length of life for those patients able to access effective and sustained treatment. The resulting restoration of the immune response is associated with a change in the clinical presentation of opportunistic infections, and the histologic reaction to pathogens. A complex combination of alterations in host response across the stages of HIV infection has been documented over the past 3 decades. The defects are seen in both acute and chronic phases of inflammation and involve innate and adaptive immunity. In advanced stages of HIV infection, the marked disruption of lymphoid tissue and loss of follicular dendritic cells limits the host's ability to process antigen and mount specific responses to pathogens. There are qualitative and quantitative defects in CD4 T cells due to HIV infection. The resulting indirect effects include loss of cytokine production, dysregulation of B-cell function, loss of cellular mediated immunity and "holes" in the immunologic repertoire that may not be restored with the use of antiretroviral therapy. Immune reconstitution allows the host to respond to and control infection, but a significant number of patients will have atypical inflammatory syndromes during the recovery period. We briefly discuss the impact of HIV infection on the immune system and give an overview of the spectrum of conditions attributed to the Immune Reconstitution Inflammatory syndrome (IRIS).

New genetic discoveries and primary immune deficiencies.

PubMed

Hernandez-Trujillo, Vivian

2014-04-01

The field of immunology has undergone recent discoveries of genetic causes for many primary immunodeficiency diseases (PIDD). The ever-expanding knowledge has led to increased understanding behind the pathophysiology of these diseases. Since these diseases are rare, the patients are frequently misdiagnosed early in the presentation of their illnesses. The identification of new genes has increased our opportunities for recognizing and making the diagnosis in patients with PIDD before they succumb to infections that may result secondary to their PIDD. Some mutations lead to a variety of presentations of severe combined immunodeficiency (SCID). The myriad and ever-growing genetic mutations which lead to SCID phenotypes have been identified in recent years. Other mutations associated with some genetic syndromes have associated immunodeficiency and are important for making the diagnosis of primary immunodeficiency in patients with some syndromes, who may otherwise be missed within the larger context of their syndromes. A variety of mutations also lead to increased susceptibility to infections due to particular organisms. These patterns of infections due to specific organisms are important keys in properly identifying the part of the immune system which is affected in these patients. This review will discuss recent genetic discoveries that enhance our understanding of these complex diseases.

Cerebral creatine deficiency syndromes: clinical aspects, treatment and pathophysiology.

PubMed

Stockler, Sylvia; Schutz, Peter W; Salomons, Gajja S

2007-01-01

Cerebral creatine deficiency syndromes (CCDSs) are a group of inborn errors of creatine metabolism comprising two autosomal recessive disorders that affect the biosynthesis of creatine--i.e. arginine:glycine amidinotransferase deficiency (AGAT; MIM 602360) and guanidinoacetate methyltransferase deficiency (GAMT; MIM 601240)--and an X-linked defect that affects the creatine transporter, SLC6A8 deficiency (SLC6A8; MIM 300036). The biochemical hallmarks of these disorders include cerebral creatine deficiency as detected in vivo by 1H magnetic resonance spectroscopy (MRS) of the brain, and specific disturbances in metabolites of creatine metabolism in body fluids. In urine and plasma, abnormal guanidinoacetic acid (GAA) levels are found in AGAT deficiency (reduced GAA) and in GAMT deficiency (increased GAA). In urine of males with SLC6A8 deficiency, an increased creatine/creatinine ratio is detected. The common clinical presentation in CCDS includes mental retardation, expressive speech and language delay, autistic like behaviour and epilepsy. Treatment of the creatine biosynthesis defects has yielded clinical improvement, while for creatine transporter deficiency, successful treatment strategies still need to be discovered. CCDSs may be responsible for a considerable fraction of children and adults affected with mental retardation of unknown etiology. Thus, screening for this group of disorders should be included in the differential diagnosis of this population. In this review, also the importance of CCDSs for the unravelling of the (patho)physiology of cerebral creatine metabolism is discussed.

HMBPP-deficient Listeria mutant immunization alters pulmonary/systemic responses, effector functions, and memory polarization of Vγ2Vδ2 T cells

Whereas infection or immunization of humans/primates with microbes coproducing HMBPP/IPP can remarkably activate Vγ2Vδ2 T cells, in vivo studies have not been done to dissect HMBPP- and IPP-driven expansion, pulmonary trafficking, effector functions, and memory polarization of Vγ2Vδ2 T cells. We define these phosphoantigen-host interplays by comparative immunizations of macaques with the HMBPP/IPP-coproducing Listeria ΔactA prfA* and HMBPP-deficient Listeria ΔactAΔgcpE prfA* mutant. The HMBPP-deficient ΔgcpE mutant shows lower ability to expand Vγ2Vδ2 T cells in vitro than the parental HMBPP-producing strain but displays comparably attenuated infectivity or immunogenicity. Respiratory immunization of macaques with the HMBPP-deficient mutant elicits lower pulmonary and systemic responses of Vγ2Vδ2 T cells compared with the HMBPP-producing vaccine strain. Interestingly, HMBPP-deficient mutant reimmunization or boosting elicits enhanced responses of Vγ2Vδ2 T cells, but the magnitude is lower than that by HMBPP-producing listeria. HMBPP-deficient listeria differentiated fewer Vγ2Vδ2 T effector cells capable of coproducing IFN-γ and TNF-α and inhibiting intracellular listeria than HMBPP-producing listeria. Furthermore, HMBPP deficiency in listerial immunization influences memory polarization of Vγ2Vδ2 T cells. Thus, both HMBPP and IPP production in listerial immunization or infection elicit systemic/pulmonary responses and differentiation of Vγ2Vδ2 T cells, but a role for HMBPP is more dominant. Findings may help devise immune intervention. PMID:25114162

Paleo-Immunology: Evidence Consistent with Insertion of a Primordial Herpes Virus-Like Element in the Origins of Acquired Immunity

PubMed Central

Dreyfus, David H.

2009-01-01

Background The RAG encoded proteins, RAG-1 and RAG-2 regulate site-specific recombination events in somatic immune B- and T-lymphocytes to generate the acquired immune repertoire. Catalytic activities of the RAG proteins are related to the recombinase functions of a pre-existing mobile DNA element in the DDE recombinase/RNAse H family, sometimes termed the “RAG transposon”. Methodology/Principal Findings Novel to this work is the suggestion that the DDE recombinase responsible for the origins of acquired immunity was encoded by a primordial herpes virus, rather than a “RAG transposon.” A subsequent “arms race” between immunity to herpes infection and the immune system obscured primary amino acid similarities between herpes and immune system proteins but preserved regulatory, structural and functional similarities between the respective recombinase proteins. In support of this hypothesis, evidence is reviewed from previous published data that a modern herpes virus protein family with properties of a viral recombinase is co-regulated with both RAG-1 and RAG-2 by closely linked cis-acting co-regulatory sequences. Structural and functional similarity is also reviewed between the putative herpes recombinase and both DDE site of the RAG-1 protein and another DDE/RNAse H family nuclease, the Argonaute protein component of RISC (RNA induced silencing complex). Conclusions/Significance A “co-regulatory” model of the origins of V(D)J recombination and the acquired immune system can account for the observed linked genomic structure of RAG-1 and RAG-2 in non-vertebrate organisms such as the sea urchin that lack an acquired immune system and V(D)J recombination. Initially the regulated expression of a viral recombinase in immune cells may have been positively selected by its ability to stimulate innate immunity to herpes virus infection rather than V(D)J recombination Unlike the “RAG-transposon” hypothesis, the proposed model can be readily tested by

Pathology in euthermic bats with white nose syndrome suggests a natural manifestation of immune reconstitution inflammatory syndrome

USGS Publications Warehouse

Meteyer, Carol U.; Barber, Daniel; Mandl, Judith N.

2012-01-01

White nose syndrome, caused by Geomyces destructans, has killed more than 5 million cave hibernating bats in eastern North America. During hibernation, the lack of inflammatory cell recruitment at the site of fungal infection and erosion is consistent with a temperature-induced inhibition of immune cell trafficking. This immune suppression allows G. destructans to colonize and erode the skin of wings, ears and muzzle of bat hosts unchecked. Yet, paradoxically, within weeks of emergence from hibernation an intense neutrophilic inflammatory response to G. destructans is generated, causing severe pathology that can contribute to death. We hypothesize that the sudden reversal of immune suppression in bats upon the return to euthermia leads to a form of immune reconstitution inflammatory syndrome (IRIS), which was first described in HIV-infected humans with low helper T lymphocyte counts and bacterial or fungal opportunistic infections. IRIS is a paradoxical and rapid worsening of symptoms in immune compromised humans upon restoration of immunity in the face of an ongoing infectious process. In humans with HIV, the restoration of adaptive immunity following suppression of HIV replication with anti-retroviral therapy (ART) can trigger severe immune-mediated tissue damage that can result in death. We propose that the sudden restoration of immune responses in bats infected with G. destructans results in an IRIS-like dysregulated immune response that causes the post-emergent pathology.

Primary Immune Deficiencies – Principles of Care

2014-01-01

Primary immune deficiencies (PIDs) are a growing group of over 230 different disorders caused by ineffective, absent or an increasing number of gain of function mutations in immune components, mainly cells and proteins. Once recognized, these rare disorders are treatable and in some cases curable. Otherwise untreated PIDs are often chronic, serious, or even fatal. The diagnosis of PIDs can be difficult due to lack of awareness or facilities for diagnosis, and management of PIDs is complex. This document was prepared by a worldwide multi-disciplinary team of specialists; it aims to set out comprehensive principles of care for PIDs. These include the role of specialized centers, the importance of registries, the need for multinational research, the role of patient organizations, management and treatment options, the requirement for sustained access to all treatments including immunoglobulin therapies and hematopoietic stem cell transplantation, important considerations for developing countries and suggestions for implementation. A range of healthcare policies and services have to be put into place by government agencies and healthcare providers, to ensure that PID patients worldwide have access to appropriate and sustainable medical and support services.

1998-10-27

Common Variable Immuno-Deficiency (CVID) is the most common symptomatic primary antibody-deficiency syndrome, but the basic immunologic defects underlying this syndrome are not well defined. We report here that among eight patients studied (six CVID and two hypogammaglobulinemic patients with recurrent infections), there is in two CVID patients a dramatic reduction in Ig V gene somatic hypermutation with 40-75% of IgG transcripts totally devoid of mutations in the circulating memory B cell compartment. Functional assays of the T cell compartment point to an intrinsic B cell defect in the process of antibody affinity maturation in these two cases.

Guillain Barre syndrome in an HIV-1-infected patient after the beginning of combined antiretroviral therapy: an immune reconstitution inflammatory syndrome?

PubMed

Fantauzzi, Alessandra; Digiulio, Maria Anna; Cavallari, Eugenio Nelson; d'Ettorre, Gabriella; Vullo, Vincenzo; Mezzaroma, Ivano

2014-01-01

HIV-1-associated Guillan-Barre syndrome (hGBS) is an ascendant progressive polyradiculoneuropathy described throughout the course of the viral disease, mainly associated with the acute retroviral syndrome. HGBS is occasionally described in severely immunocompromised subjects in the context of the immune reconstitution inflammatory syndrome. The case described occurred soon after the start of a combined antiretroviral treatment in an HIV-1 infected patient with ulcerative colitis in the absence of severe immunosuppression. This manifestation may be interpreted as an uncommon appearance of an immune reconstitution syndrome in the presence of a predisposing autoimmune pathology.

Herbal compatibility of traditional Chinese medical formulas for acquired immunodeficiency syndrome.

Cui, Meng; Li, Jinghua; Li, Haiyan; Song, Chunxin

2012-09-01

Because herbal compatibility is one of the most important reasons why Traditional Chinese Medcine (TCM) formulas are effective for acquired immunodeficiency syndrome (AIDS), our study aimed to determine the compatibility of herbs based on published AIDS clinical research in Chinese periodicals. To achieve this aim, we designed a new data-mining algorithm according to TCM data characteristics. We found 25 clinical AIDS studies, all using Chinese herbs for treatment, in the Traditional Chinese Medicine Database System, and information on diagnosis and treatment was extracted. To find out herbal compatibility, especially the formulae for herbal combinations, we proposed an improved association rule algorithm based on the frequency of combinations. In this algorithm, all the compatibility relationships were displayed in a tree structure, by which the relationship between formulas and their derivation could be clearly inferred. Data analysis showed that approximately 100 herbs have been used for treating AIDS. Based on the whole herb compatibility tree, we calculated a basic formula for AIDS: Huang Qi combined with Ren Shen, Fu Ling, Bai Zhu, Bai Zhu, Dang Gui, and Bai Shao. This formula, deriving from most of clinical prescriptions, and was chosed by most of clinicians for AIDS treatment. From data mining we found that Qi replenishment and detoxification were the main treatment principles, which coincided with the AIDS pathological mechanism in which immune function is destroyed by human immunodeficiency virus (HIV). Our data-mining results suggest that the core TCM treatment of AIDS is replenishing Qi and detoxification, by which AIDS patients' immune system may be enhanced. Compatibility of Huang Qi with some frequently-used herbs have shown real efficacy in clinical practice, which warrants pharmacological research in the future.

A 33-year-old heterosexual white man underwent a liver biopsy for determination of mild elevation of aminotransferase levels (aspartate aminotransferase, two times; alanine aminotransferase, three times). The patient had acquired immunodeficiency syndrome (stage IVC2) with tuberculosis of the lymph nodes. Antibody to hepatitis B surface antigen and antibody to hepatitis B core antigen were positive. Syphillis tests were positive. Liver architecture was normal; sinusoids were dilated with perisinusoidal, centrilobular, and portal fibrosis. On a 1-micron-thick section and under electron microscopy, perisinusoidal cells appeared to be massively loaded with lipids, while endothelial cells contained numerous dense bodies. Some hepatocytes presented evidence of cell damage. Sinusoids were infiltrated by an increased number of lymphocytes and macrophages. This patient who had recently been treated for tuberculosis was not taking extra vitamin A. He had no disease so far reported as being associated with perisinusoidal cell hypertrophy. This case and others are evidence that acquired immunodeficiency syndrome represents another cause of perisinusoidal cell hypertrophy in which there is no documented hypervitaminosis A.

Biotinidase deficiency is an autosomal recessively inherited metabolic disorder that can be easily and effectively treated with pharmacological doses of the vitamin, biotin. Untreated children with profound biotinidase deficiency may exhibit neurological, cutaneous and cellular immunological abnormalities, specifically candida infections. To better understand the immunological dysfunction in some symptomatic individuals with biotinidase deficiency, we studied various aspects of immunological function in a genetically engineered knock-out mouse with biotinidase deficiency. The mouse has no detectable biotinidase activity and develops neurological and cutaneous symptoms similar to those seen in symptomatic children with the disorder. Mice with profound biotinidase deficiency on a biotin-restricted diet had smaller thymuses and spleens than identical mice fed a biotin-replete diet or wildtype mice on either diet; however, the organ to body weight ratios were not significantly different. Thymus histology was normal. Splenocyte subpopulation study showed a significant increase in CD4 positive cells. In addition, in vitro lymphocyte proliferation assays consistently showed diminished proliferation in response to various immunological stimuli. Not all symptomatic individuals with profound biotinidase deficiency develop immunological dysfunction; however, our results do show significant alterations in cellular immunological function that may contribute and/or provide a mechanism(s) for the cellular immunity abnormalities in individuals with biotinidase deficiency.

Immune deficiency vs. immune excess in inflammatory bowel diseases-STAT3 as a rheo-STAT of intestinal homeostasis.

PubMed

Leppkes, Moritz; Neurath, Markus F; Herrmann, Martin; Becker, Christoph

2016-01-01

Genome-wide association studies have provided many genetic alterations, conferring susceptibility to multifactorial polygenic diseases, such as inflammatory bowel diseases. Yet, how specific genetic alterations functionally affect intestinal inflammation often remains elusive. It is noteworthy that a large overlap of genes involved in immune deficiencies with those conferring inflammatory bowel disease risk has been noted. This has provided new arguments for the debate on whether inflammatory bowel disease arises from either an excess or a deficiency in the immune system. In this review, we highlight the functional effect of an inflammatory bowel disease-risk allele, which cannot be deduced from genome-wide association studies data alone. As exemplified by the transcription factor signal transducer and activator of transcription 3 (STAT3), we show that a single gene can have a plethora of effects in various cell types of the gut. These effects may individually contribute to the restoration of intestinal homeostasis on the one hand or pave the way for excessive immunopathology on the other, as an inflammatory "rheo-STAT". © Society for Leukocyte Biology.

To reclassify deaths of women infected with the human immunodeficiency virus/acquired immunodeficiency syndrome in pregnancy and childbirth in the State of Pernambuco, Brazil, from 2000 to 2010. A descriptive exploratory study, developed from the following steps: translation to Portuguese of the item "HIV and aids" of the United Nations document "The WHO application of ICD-10 to deaths during pregnancy, childbirth and the puerperium: DCI MM 2012"; development of a classification algorithm of deaths of women living with the human immunodeficiency virus/acquired immunodeficiency syndrome in pregnancy and childbirth; and reclassification of deaths by a group of experts. Among the 25 reclassified deaths, 12 were due to human immunodeficiency virus/acquired immunodeficiency syndrome, and pregnancy condition was coexisting; 9 were reclassified as indirect maternal death, with O98.7 code, proposed by the World Health Organization; 2 as direct/indirect maternal death; and 2 were considered indeterminate. The reclassification showed a possible pattern of change in maternal mortality, since most of the deaths were attributed to the virus and may lead to a reduction in deaths from maternal causes. The algorithm will subsidize the use of the new classification of maternal death and human immunodeficiency virus/acquired immunodeficiency syndrome.

HIV "controllers" are persons infected with human immunodeficiency virus, type I (HIV) who maintain long-term control of viremia without antiviral therapy and who usually do not develop the acquired immune deficiency syndrome (AIDS). In this study, we have correlated results from polychromatic flow cytometry and oligonucleotide expression arrays to characterize the mucosal immune responses of these subjects in relation to untreated HIV(+) persons with high viral loads and progressive disease ("noncontrollers"). Paired peripheral blood and rectosigmoid biopsies were analyzed from 9 controllers and 11 noncontrollers. Several cellular immune parameters were found to be concordant between the 2 compartments. Compared with noncontrollers, the mucosal tissues of controllers had similar levels of effector T cells and fewer regulatory T cells (Tregs). Using principal component analysis to correlate immunologic parameters with gene expression profiles, transcripts were identified that accurately distinguished between controllers and noncontrollers. Direct 2-way comparison also revealed genes that are significantly different in their expression between controllers and noncontrollers, all of which had reduced expression in controllers. In addition to providing an approach that integrates flow cytometry datasets with transcriptional profiling analysis, these results underscore the importance of the sustained inflammatory response that attends progressive HIV disease.

To comparatively analyse the objective characteristics of different syndrome types of qi-disturbance-induced blood stasis syndrome (QDBS) in the pathogenetic evolution of unstable angina coronary heart disease (UA-CHD). Seventy-eight patients with UA-CHD of QDBS were differentiated into 2 groups: 55 in the qi-deficiency-induced blood-stasis syndrome group (A) and 23 in the qi-stagnation-induced blood-stasis syndrome group (B). The comparative analysis on them was carried out through comparing their blood pressure, glucose and lipid metabolisms, coagulation function, thyroid function and inflammation reaction changes, etc. In the pathogenetic process of qi-disturbance induced blood stasis, the initiating age, levels of HbA1c, TSH, PT and APTT between the two groups were significantly different (P < 0.05). Levels of TNF-alpha and LN were higher and levels of sIgA lower in patients than those in healthy subjects (P < 0.05). Inflammation immune reaction may play an important role in the pathogenetic process of blood-stasis syndrome, and the functional disturbance of hypothalamus, pituitary and endocrinal secretion induced by emotional stress is possibly the essence of qi-stagnation induced blood stasis syndrome.

Advances in understanding the pathogenesis of HLH.

Usmani, G Naheed; Woda, Bruce A; Newburger, Peter E

2013-06-01

Haemophagocytic lymphohistiocytosis (HLH) is a hyperinflammatory disorder resulting from immune dysfunction reflecting either primary immune deficiency or acquired failure of normal immune homeostasis. Familial HLH includes autosomal recessive and X-linked disorders characterized by uncontrolled activation of T cells and macrophages and overproduction of inflammatory cytokines, secondary to defects in genes encoding proteins involved in granule-dependent cytolytic pathways. In older children and adults, HLH is associated more often with infections, malignancies, autoimmune diseases, and acquired immune deficiencies. HLH, macrophage activation syndrome, sepsis, and systemic inflammatory response syndrome are different clinical entities that probably represent a common immunopathological state, termed cytokine storm. These conditions may be clinically indistinguishable; all include massive inflammatory response, elevated serum cytokine levels, multi-organ involvement, haemophagocytic macrophages, and often death. Tissues of haematopoietic and lymphoid function are directly involved; other organs are secondarily damaged by circulating cytokines and chemokines. Haemophagocytic disorders are now increasingly diagnosed in the context of severe inflammatory reactions to viruses, malignancies and systemic connective tissue diseases. Many of these cases may reflect underlying genetic predispositions to HLH. The detection of gene defects has contributed considerably to our understanding of HLH, but the mechanisms leading to acquired HLH have yet to be fully determined. © 2013 John Wiley & Sons Ltd.

Hospital admissions for vitamin D related conditions and subsequent immune-mediated disease: record-linkage studies

PubMed Central

2013-01-01

Background Previous studies have suggested that there may be an association between vitamin D deficiency and the risk of developing immune-mediated diseases. Methods We analyzed a database of linked statistical records of hospital admissions and death registrations for the whole of England (from 1999 to 2011). Rate ratios for immune-mediated disease were determined, comparing vitamin D deficient cohorts (individuals admitted for vitamin D deficiency or markers of vitamin D deficiency) with comparison cohorts. Results After hospital admission for either vitamin D deficiency, osteomalacia or rickets, there were significantly elevated rates of Addison’s disease, ankylosing spondylitis, autoimmune hemolytic anemia, chronic active hepatitis, celiac disease, Crohn’s disease, diabetes mellitus, pemphigoid, pernicious anemia, primary biliary cirrhosis, rheumatoid arthritis, Sjogren’s syndrome, systemic lupus erythematosus, thyrotoxicosis, and significantly reduced risks for asthma and myxoedema. Conclusions This study shows that patients with vitamin D deficiency may have an increased risk of developing some immune-mediated diseases, although we cannot rule out reverse causality or confounding. Further study of these associations is warranted and these data may aid further public health studies. PMID:23885887

Clinical Endocannabinoid Deficiency Reconsidered: Current Research Supports the Theory in Migraine, Fibromyalgia, Irritable Bowel, and Other Treatment-Resistant Syndromes.

PubMed

Russo, Ethan B

2016-01-01

Medicine continues to struggle in its approaches to numerous common subjective pain syndromes that lack objective signs and remain treatment resistant. Foremost among these are migraine, fibromyalgia, and irritable bowel syndrome, disorders that may overlap in their affected populations and whose sufferers have all endured the stigma of a psychosomatic label, as well as the failure of endless pharmacotherapeutic interventions with substandard benefit. The commonality in symptomatology in these conditions displaying hyperalgesia and central sensitization with possible common underlying pathophysiology suggests that a clinical endocannabinoid deficiency might characterize their origin. Its base hypothesis is that all humans have an underlying endocannabinoid tone that is a reflection of levels of the endocannabinoids, anandamide (arachidonylethanolamide), and 2-arachidonoylglycerol, their production, metabolism, and the relative abundance and state of cannabinoid receptors. Its theory is that in certain conditions, whether congenital or acquired, endocannabinoid tone becomes deficient and productive of pathophysiological syndromes. When first proposed in 2001 and subsequently, this theory was based on genetic overlap and comorbidity, patterns of symptomatology that could be mediated by the endocannabinoid system (ECS), and the fact that exogenous cannabinoid treatment frequently provided symptomatic benefit. However, objective proof and formal clinical trial data were lacking. Currently, however, statistically significant differences in cerebrospinal fluid anandamide levels have been documented in migraineurs, and advanced imaging studies have demonstrated ECS hypofunction in post-traumatic stress disorder. Additional studies have provided a firmer foundation for the theory, while clinical data have also produced evidence for decreased pain, improved sleep, and other benefits to cannabinoid treatment and adjunctive lifestyle approaches affecting the ECS.

This article contains data from a study of New Jersey's home and community-based Medicaid waiver program for persons with symptomatic human immunodeficiency virus illness. Major findings include lower hospital costs and utilization for waiver participants compared with general Medicaid acquired immunodeficiency syndrome admissions in New Jersey. Average program expenditures were $2,400 per person per month. Based on study findings, it is evident that the waiver program is an important means of providing financial benefits and access to services and that comprehensive case management is a critical factor in assuring program quality.

Taylor, G. R.; Kropp, K. D.; Molina, T. C.

1978-01-01

The paper presents a microflora analysis of a 5-year-old male child with severe combined immune deficiency who was delivered by Caesarean section and continuously maintained in an isolator. Despite precautions, it was found that the child had come in contact with at least 54 different microbial contaminants. While his skin autoflora was similar to that of a reference group of healthy male adults in numbers of different species and the number of viable cells present per square centimeter of surface area, the subject's autoflora differed from the reference group in that significantly fewer anaerobic species were recovered from the patient's mouth and feces. It is suggested that the child's remaining disease free shows that the reported bacteria are noninvasive or that the unaffected components of the child's immune defense mechanisms are important.

Growth hormone deficiency (GHD) in adults is characterized by reduced quality of life and physical fitness, skeletal fragility, increased weight and cardiovascular risk. It may be found in (over-) treated acromegaly as well as in active Cushing's syndrome. Hypopituitarism may develop in patients after definitive treatment of acromegaly, although the exact prevalence of GHD in this population is still uncertain because of limited awareness, and scarce and conflicting data so far available. Because GHD associated with acromegaly and Cushing's syndrome may yield adverse consequences on similar target systems, the final outcomes of some complications of both acromegaly and Cushing's syndrome may be further affected by the occurrence of GHD. It is still largely unknown, however, whether GHD in patients with post-acromegaly or active Cushing's syndrome (e.g. pharmacologic glucocorticoid treatment) may benefit from GH replacement. We review the diagnostic, clinical and therapeutic aspects of GHD in adults treated for acromegaly and in those with active Cushing's syndrome. Copyright © 2017 Elsevier Ltd. All rights reserved.

Granzyme A is a protease implicated in the degradation of intracellular DNA. Nucleotide complexes are known triggers of systemic autoimmunity, but a role in organ-specific autoimmune disease has not been demonstrated. To investigate whether such a mechanism could be an endogenous trigger for autoimmunity, we examined the impact of granzyme A deficiency in the NOD mouse model of autoimmune diabetes. Granzyme A deficiency resulted in an increased incidence in diabetes associated with accumulation of ssDNA in immune cells and induction of an interferon response in pancreatic islets. Central tolerance to proinsulin in transgenic NOD mice was broken on a granzyme A-deficient background. We have identified a novel endogenous trigger for autoimmune diabetes and an in vivo role for granzyme A in maintaining immune tolerance. © 2017 by the American Diabetes Association.

To explore Chinese medicine (CM) syndrome distribution of chronic hepatitis B virus (HBV) carriers in immunotolerant phase (ITP). One hundred and eighty-five chronic HBV carriers in ITP, seen in the Third Affiliated Hospital of Sun Yat-sen University from May 2009 to December 2010, were admitted in an observational study under the guidance of CM. Patients' CM symptoms and signs, demographics, liver biochemistries, and qualitative HBV DNA were recorded in the questionnaires. CM syndromes were then differentiated to 15 detailed types and analyzed by generalization. Lastly, the location, pathogenic factors and nature of the disease were also assessed. When CM syndrome patterns were differentiated to 15 types, there were 27 (15%) no syndrome cases, 94 (50%) single syndrome cases and 64 (35%) compound syndromes cases. The main detailed syndromes included Liver (Gan)-qi depression (LQD), Kidney (Shen)-qi deficiency (KQD), Spleen (Pi)-qi deficiency (SQD) and Kidney-yang deficiency (KYAD). After CM syndromes generalized to five types, their frequency was Spleen-Kidney deficiency (SKD)>LQD>inner dampness-heat retention (IDHR)>Liver-Kidney deficiency (LKD)>blood stasis blocking collateral (BSBC). SKD and LQD occupied 64%. The disease location included Liver, Gallbladder (Dan), Spleen, Stomach (Wei) and Kidney. The pathogenic factors were mainly qi stagnation, qi deficiency, yang deficiency, concurrently dampness-heat and blood stasis. The deficiency syndrome was more than excess syndrome in its nature. Most of chronic HBV carriers in ITP have their CM syndrome, and the most common types are SKAD, LQD. This study suggests that the natural history may be improved through breaking the state of immune tolerance or shorten the time of ITP by strengthening Spleen-Kidney and reliving Liver qi.

To study the correlation between Chinese medical types of coronary heart disease (CHD) [i.e., phlegm turbidity syndrome (PTS) and qi deficiency syndrome (QDS)] and their metabolites. Recruited were 65 CHD patients including 37 cases of PTS and 28 cases of QDS. Serum endogenous metabolites in the two syndrome types were determined by gas chromatograph-mass spectrometer-computer (GC/MS), and their differences between their metabolic profiles analyzed. More than 100 chromatographic peaks were totally scanned. Chromatograms obtained was matched with mass spectrum bank, and finally we got the category contribution value of 46 kinds of substances. Results of MCTree analysis showed patients of PTS and patients of QDS could be effectively distinguished. Compounds contributing to identify the two syndromes were sequenced as serine, valine, 2 hydroxy propionic acid. Comparison of metabolites showed contents of serine and 2 hydroxy propionic acid were higher in patients of PTS than in patients of QDS (P<0.05). The differences in the metabonomics of CHD TCM syndrome types could provide material bases for TCM syndrome differentiation of CHD, indicating that metabonomics technologies might become a new research method for TCM syndrome typing.

Acquired antiprothrombin antibodies: an unusual cause of bleeding.

PubMed

Carvalho, Cristiana; Viveiro, Carolina; Maia, Paulo; Rezende, Teresa

2013-01-07

Acquired inhibitors of coagulation causing bleeding manifestations are rare in children. They emerge, normally in the context of autoimmune diseases or drug ingestion, but transient and self-limiting cases can occur after viral infection. We describe, an otherwise healthy, 7-year-old girl who had gingival bleeding after a tooth extraction. The prothrombin time (PT) and the activated partial thromboplastin time (APTT) were both prolonged with evidence of an immediate acting inhibitor (lupic anticoagulant). Further coagulation studies demonstrated prothrombin (FII) deficiency and prothrombin directed (FII) antibodies. The serological tests to detect an underlying autoimmune disease were all negative. The coagulation studies normalised alongside the disappearance of the antibody. This article presents lupus anticoagulant hypoprothrombinaemia syndrome (LAHS) as a rare case of acquired bleeding diathesis in childhood.

We assessed non-liver-related non-acquired immunodeficiency syndrome (AIDS)-related (NLR-NAR) events and mortality in a cohort of human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients treated with interferon (IFN) and ribavirin (RBV), between 2000 and 2008. The censoring date was May 31, 2014. Cox regression analysis was performed to assess the adjusted hazard rate (HR) of overall death in responders and nonresponders. Fine and Gray regression analysis was conducted to determine the adjusted subhazard rate (sHR) of NLR deaths and NLR-NAR events considering death as the competing risk. The NLR-NAR events analyzed included diabetes mellitus, chronic renal failure, cardiovascular events, NLR-NAR cancer, bone events, and non-AIDS-related infections. The variables for adjustment were age, sex, past AIDS, HIV transmission category, nadir CD4 + T-cell count, antiretroviral therapy, HIV RNA, liver fibrosis, HCV genotype, and exposure to specific anti-HIV drugs. Of the 1,625 patients included, 592 (36%) had a sustained viral response (SVR). After a median 5-year follow-up, SVR was found to be associated with a significant decrease in the hazard of diabetes mellitus (sHR, 0.57; 95% confidence interval [CI], 0.35-0.93; P = 0.024) and decline in the hazard of chronic renal failure close to the threshold of significance (sHR, 0.43; 95% CI, 0.17-1.09; P = 0.075). Our data suggest that eradication of HCV in coinfected patients is associated not only with a reduction in the frequency of death, HIV progression, and liver-related events, but also with a reduced hazard of diabetes mellitus and possibly of chronic renal failure. These findings argue for the prescription of HCV therapy in coinfected patients regardless of fibrosis stage. (Hepatology 2017;66:344-356). © 2017 The Authors.

Coping with uncertainty: nutrient deficiencies motivate insect migration at a cost to immunity.

PubMed

Srygley, Robert B; Lorch, Patrick D

2013-12-01

Migration often is associated with movement away from areas with depleted nutrients or other resources, and yet migration itself is energetically demanding. Migrating Mormon crickets Anabrus simplex (Orthoptera: Tettigoniidae) lack nutrients, and supplementation of deficient nutrients slows migratory movements and enhances specific aspects of their immune systems. Migrants deficient in proteins have less spontaneous phenoloxidase (PO) activity, whereas those deficient in carbohydrates have lower lysozyme-like anti-bacterial titers with a proposed compromise between migratory and anti-bacterial activities. To investigate the relationship between diet, movement, and immunity further, we removed Mormon crickets from a migratory band and offered each cricket one of five diets: high protein, high carbohydrate, equal weight of proteins and carbohydrates (P + C), vitamins only, or water only for 1 h. We then attached a radio, returned each to the migratory band, and recaptured them 18-24 h later. Mormon crickets fed protein moved the furthest, those with only water or only vitamins moved less, and those fed carbohydrates or P + C moved the least. Standard intake trials also indicated that the Mormon crickets were deficient in carbohydrates. Consistent with a previous study, lysozyme-like anti-bacterial activity was greatest in those fed carbohydrates, and there was no difference between those fed water, protein, or P + C. Crickets were removed from the same migratory band and fed one of four diets: high P, high C, P + C, or vitamins only, for 1 h. Then the crickets were held in captivity with water only for 4 or 24 h before blood was drawn. Immunity measures did not differ between times of draw. Diet treatments had no effect on anti-bacterial activity of captive Mormon crickets, whereas total PO was greater in those fed protein. These results support the hypothesis of a direct compromise between migratory and anti-bacterial activities, whereas PO is compromised by low

Systemic Lupus Erythematosus and Deficiencies of Early Components of the Complement Classical Pathway

PubMed Central

Macedo, Ana Catarina Lunz; Isaac, Lourdes

2016-01-01

The complement system plays an important role in the innate and acquired immune response against pathogens. It consists of more than 30 proteins found in soluble form or attached to cell membranes. Most complement proteins circulate in inactive forms and can be sequentially activated by the classical, alternative, or lectin pathways. Biological functions, such as opsonization, removal of apoptotic cells, adjuvant function, activation of B lymphocytes, degranulation of mast cells and basophils, and solubilization and clearance of immune complex and cell lysis, are dependent on complement activation. Although the activation of the complement system is important to avoid infections, it also can contribute to the inflammatory response triggered by immune complex deposition in tissues in autoimmune diseases. Paradoxically, the deficiency of early complement proteins from the classical pathway (CP) is strongly associated with development of systemic lupus erythematous (SLE) – mainly C1q deficiency (93%) and C4 deficiency (75%). The aim of this review is to focus on the deficiencies of early components of the CP (C1q, C1r, C1s, C4, and C2) proteins in SLE patients. PMID:26941740

Kidney yang deficiency syndrome, a diagnostic pattern in Chinese medicine, is similar with clinical features of the glucocorticoid withdrawal syndrome. The aim of this present study was to explore low molecular mass differentiating metabolites between control group and model group of kidney yang deficiency rats induced with corticosterone as well as the therapeutic effect of Shen Qi Pill, a classic traditional Chinese medicine formula for treating Kidney yang deficiency syndrome in China. This study utilized ultra-performance liquid chromatography coupled with electrospray ionization synapt quadrupole time-of-flight high definition mass spectrometry (UPLC/ESI-SYNAPT-QTOF-HDMS) to identify the underlying biomarkers for clarifying mechanism of Shen Qi Pill in treating Kidney yang deficiency syndrome based on metabolite profiling of the serum samples and in conjunction with multivariate and pathway analysis. Meanwhile, blood biochemistry assay and histopathology were examined to identify specific changes in the model group rats. Distinct changes in the pattern of metabolites were observed by UPLC-HDMS. The changes in metabolic profiling were restored to their baseline values after treatment with Shen Qi Pill according to the combined with a principal component analysis (PCA) score plots. Altogether, the current metabolomics approach based on UPLC-HDMS and orthogonal projection to latent structures discriminate analysis (OPLS-DA) demonstrated 27 ions (18 in the negative mode, 9 in the positive mode, 17 ions restored by Shen Qi Pill). These results indicated that effectiveness of Shen Qi Pill in Kidney yang deficiency syndrome rats induced a substantial change in the metabolic profiles by regulating the biomarkers and adjusting the metabolic disorder. It suggested that the metabolomics approach was a powerful approach for elucidation of pathologic changes of Chinese medicine syndrome and action mechanisms of traditional Chinese medicine.

A 53-year-old female developed epigastric discomfort and back pain in 2007. Diagnostic imaging studies demonstrated a soft tissue tumor with heterogeneous enhancement in the anterior mediastinum and multiple nodules in the right lung. She underwent expanded thymectomy with subtotal resection of the right lung. The pathological diagnosis was primary thymic mucosa-associated lymphoid tissue (MALT) lymphoma. The patient complained of ocular discomfort, oral dryness and continuous nasal bleeding in 2007. Detailed examination led to a diagnosis of Sjögren syndrome and acquired von Willebrand syndrome. Rituximab treatment for residual disease achieved not only a reduction of the lung MALT lymphoma but also clinical and hematological remission of both syndromes. This is, to our knowledge, the first reported case of primary thymic MALT lymphoma accompanied by Sjögren and acquired von Willebrand syndromes.

The aim of the present study was to investigate the effects of selenium (Se) deficiency on autophagy-related genes and on ultrastructural changes in the spleen, bursa of Fabricius, and thymus of chickens. The Se deficiency group was fed a basal diet containing Se at 0.033 mg/kg and the control group was fed the same basal diet containing Se at 0.15 mg/kg. The messenger RNA (mRNA) levels of the autophagy genes microtubule-associated protein 1 light chain 3 (LC3)-I, LC3-II, Beclin 1, dynein, autophagy associated gene 5 (ATG5), and target of rapamycin complex 1 (TORC1) were assessed using real-time qPCR. The protein levels of LC3-II, Beclin 1, and dynein were investigated using western blot analysis. Furthermore, the ultrastructure was observed using an electron microscope. The results indicated that spleen mRNA levels of LC3-I, LC3-II, Beclin 1, dynein, ATG5, and TORC1 and the protein levels of LC3-II, Beclin 1, and dynein were increased in the Se deficiency group compared with the control group. In the bursa of Fabricius, the mRNA levels of LC3-I, LC3-II, Beclin 1, dynein, ATG5, and TORC1 and the protein levels of Beclin 1 and dynein were increased; furthermore, the protein level of LC3-II was decreased in the Se deficiency group compared to the control group. In the thymus, the mRNA levels of LC3-I, Beclin 1, and ATG5 increased; the levels of LC3-II, dynein, and TORC1 were decreased; the protein level of Beclin 1 increased; and the levels of LC3-II and dynein decreased in the Se deficiency group compared to those in the control group. Further cellular morphological changes, such as autophagy vacuoles, autolysosomes, and lysosomal degradation, were observed in the spleen, bursa of Fabricius, and thymus of the Se-deficiency group. In summary, Se deficiency caused changes in autophagy-related genes, which increased the autophagic process and also caused structural damages to the immune organs of chickens.

To clarify this problem, we studied 64 children with Down syndrome (DS) compared with an age-matched control group. All children had always lived at home. All the DS children were negative for hepatitis B surface antigen. Serum zinc concentration in the DS group was on average 12 micrograms/dl lower than age-matched control children. They also had significantly lower levels of immunoglobulin M, total lymphocyte count, T and B lymphocytes, and T helper and suppressor cells. In vitro lymphocyte response to phytohemagglutinin and concanavalin A was significantly reduced at all ages in the DS group. Lymphocyte response to pokeweed mitogen increased with age in control children but decreased in the DS children. By 18 yr, the mean response for DS was 60000 cpm lower than controls. The DS group had significantly higher concentrations of immunoglobulins A and G than controls and the difference increased with age. Complement fractions C3 and C4 were also higher in the DS group at all ages. The number of HNK-1 positive cells was higher in the DS group than controls at all ages. When hepatitis and institutionalization are excluded as confounding factors, DS children still differ in both humoral and cell-mediated immunity from an age-matched control group.

Clinical problems of colorectal cancer and endometrial cancer cases with unknown cause of tumor mismatch repair deficiency (suspected Lynch syndrome).

Carriers of a germline mutation in one of the DNA mismatch repair (MMR) genes have a high risk of developing numerous different cancers, predominantly colorectal cancer and endometrial cancer (known as Lynch syndrome). MMR gene mutation carriers develop tumors with MMR deficiency identified by tumor microsatellite instability or immunohistochemical loss of MMR protein expression. Tumor MMR deficiency is used to identify individuals most likely to carry an MMR gene mutation. However, MMR deficiency can also result from somatic inactivation, most commonly methylation of the MLH1 gene promoter. As tumor MMR testing of all incident colorectal and endometrial cancers (universal screening) is becoming increasingly adopted, a growing clinical problem is emerging for individuals who have tumors that show MMR deficiency who are subsequently found not to carry an MMR gene mutation after genetic testing using the current diagnostic approaches (Sanger sequencing and multiplex ligation-dependent probe amplification) and who also show no evidence of MLH1 methylation. The inability to determine the underlying cause of tumor MMR deficiency in these "Lynch-like" or "suspected Lynch syndrome" cases has significant implications on the clinical management of these individuals and their relatives. When the data from published studies are combined, 59% (95% confidence interval [CI]: 55% to 64%) of colorectal cancers and 52% (95% CI: 41% to 62%) of endometrial cancers with MMR deficiency were identified as suspected Lynch syndrome. Recent studies estimated that colorectal cancer risk for relatives of suspected Lynch syndrome cases is lower than for relatives of those with MMR gene mutations, but higher than for relatives of those with tumor MMR deficiency resulting from methylation of the MLH1 gene promoter. The cause of tumor MMR deficiency in suspected Lynch syndrome cases is likely due to either unidentified germline MMR gene mutations, somatic cell mosaicism, or biallelic somatic

Numerous syndromic forms of intellectual disability have been described including those with abnormal sweating pattern. To describe the clinical and molecular analysis of a large multiplex consanguineous Saudi family with an unusual constellation of severe intellectual disability, hypohidrosis, abnormal teeth, and acquired microcephaly. Clinical evaluation, autozygosity mapping, exome sequencing, and expression analysis. Autozygosity mapping revealed a single critical locus corresponding to chr13:39 338 062-40 857 430. Exome sequencing uncovered a deep intronic (NM_020751.2:c.1167-24A>G) variant in COG6 that largely replaces the consensus acceptor site, resulting in pronounced reduction of the normal transcript and consequent deficiency of COG6 protein. Patient cells also exhibited pronounced deficiency of STX6, consistent with the established stabilising effect of COG6 on STX6. Four additional patients representing two families of the same tribal origin as the original family were found to have the same mutation, confirming a founder effect. Remarkably, none of the patients displayed any detectable abnormality in the glycosylation pattern of transferrin, which contradicts a previously published report of a patient whose abnormal glycosylation pattern was presumed to be caused by a missense variant in COG6. Our data implicate COG6 in the pathogenesis of a novel hypohidrotic disorder in humans that is distinct from congenital disorders of glycosylation.

Leptin and Mucosal Immunity

PubMed Central

Mackey-Lawrence, Nicole M.; Petri, William A.

2012-01-01

Enhanced susceptibility to infection has long been recognized in children with congenital deficiency of leptin or its receptor. Studies in mice have demonstrated that leptin deficiency affects both the innate and acquired immune systems. Here we review recent studies that demonstrate the impact on immunity of a common non-synonomous polymorphism of the leptin receptor. In a Bangladesh cohort of children, the presence of two copies of the ancestral Q223 allele was significantly associated with resistance to amebiasis. Children and mice with at least one copy of the leptin receptor 223R mutation were more susceptible to amebic colitis. Leptin signaling in the intestinal epithelium and downstream STAT3 and SHP2 signaling were required for protection in the murine model of amebic colitis. Murine models have also implicated leptin in protection from other infections including M. tuberculosis, K. pneumoniae and S. pneumoniae. Thus, the role of leptin signaling in infectious disease and specifically leptin-mediated protection of the intestinal epithelium will be the focus of this review. PMID:22692456

Acquired immune response to oncogenic human papillomavirus associated with prophylactic cervical cancer vaccines.

PubMed

Einstein, Mark H

2008-04-01

Human papillomavirus (HPV) is a common infection among women and a necessary cause of cervical cancer. Oncogenic HPV types infecting the anogenital tract have the potential to induce natural immunity, but at present we do not clearly understand the natural history of infection in humans and the mechanisms by which the virus can evade the host immune response. Natural acquired immune responses against HPV may be involved in the clearance of infection, but persistent infection with oncogenic virus types leads to the development of precancerous lesions and cancer. B cell responses are important for viral neutralization, but antibody responses in patients with cervical cancer are poor. Prophylactic vaccines targeting oncogenic virus types associated with cervical cancer have the potential to prevent up to 80% of cervical cancers by targeting HPV types 16 and 18. Clinical data show that prophylactic vaccines are effective in inducing antibody responses and in preventing persistent infection with HPV, as well as the subsequent development of high-grade cervical intraepithelial neoplasia. This article reviews the known data regarding natural immune responses to HPV and those developed by prophylactic vaccination.

Immune dysfunction in cirrhosis

Sipeki, Nora; Antal-Szalmas, Peter; Lakatos, Peter L; Papp, Maria

2014-01-01

Innate and adaptive immune dysfunction, also referred to as cirrhosis-associated immune dysfunction syndrome, is a major component of cirrhosis, and plays a pivotal role in the pathogenesis of both the acute and chronic worsening of liver function. During the evolution of the disease, acute decompensation events associated with organ failure(s), so-called acute-on chronic liver failure, and chronic decompensation with progression of liver fibrosis and also development of disease specific complications, comprise distinct clinical entities with different immunopathology mechanisms. Enhanced bacterial translocation associated with systemic endotoxemia and increased occurrence of systemic bacterial infections have substantial impacts on both clinical situations. Acute and chronic exposure to bacteria and/or their products, however, can result in variable clinical consequences. The immune status of patients is not constant during the illness; consequently, alterations of the balance between pro- and anti-inflammatory processes result in very different dynamic courses. In this review we give a detailed overview of acquired immune dysfunction and its consequences for cirrhosis. We demonstrate the substantial influence of inherited innate immune dysfunction on acute and chronic inflammatory processes in cirrhosis caused by the pre-existing acquired immune dysfunction with limited compensatory mechanisms. Moreover, we highlight the current facts and future perspectives of how the assessment of immune dysfunction can assist clinicians in everyday practical decision-making when establishing treatment and care strategies for the patients with end-stage liver disease. Early and efficient recognition of inappropriate performance of the immune system is essential for overcoming complications, delaying progression and reducing mortality. PMID:24627592

Magnesium deficiency and metabolic syndrome: stress and inflammation may reflect calcium activation.

PubMed

Rayssiguier, Yves; Libako, Patrycja; Nowacki, Wojciech; Rock, Edmond

2010-06-01

Magnesium (Mg) intake is inadequate in the western diet and metabolic syndrome is highly prevalent in populations around the world. Epidemiological studies suggest that high Mg intake may reduce the risk but the possibility of confounding factors exists, given the strong association between Mg and other beneficial nutriments (vegetables, fibers, cereals). The concept that metabolic syndrome is an inflammatory condition may explain the role of Mg.Mg deficiency results in a stress effect and increased susceptibility to physiological damage produced by stress. Stress activates the hypothalamic-pituitary-adrenal axis (HPA) axis and the sympathetic nervous system. The activation of the renin-angiotensin-aldosterone system is a factor in the development of insulin resistance by increasing oxidative stress. In both humans and rats, aldosteronism results in an immunostimulatory state and leads to an inflammatory phenotype. Stress response induces the release of large quantities of excitatory amino acids and activates the nuclear factor NFkappaB, promoting translation of molecules involved in cell regulation, metabolism and apoptosis. The rise in neuropeptides is also well documented. Stress-induced HPA activation has been identified to play an important role in the preferential body fat accumulation but evidence that Mg is involved in body weight regulation is lacking. One of the earliest events in the acute response to stress is endothelial dysfunction. Endothelial cells actively contribute to inflammation by elaborating cytokines, synthesizing chemical mediators and expressing adhesion molecules. Experimental Mg deficiency in rats induces a clinical inflammatory syndrome characterized by leukocyte and macrophage activation, synthesis of inflammatory cytokines and acute phase proteins, extensive production of free radicals. An increase in extracellular Mg concentration decreases inflammatory effects, while reduction in extracellular Mg results in cell activation. The

Acquired immunodeficiency syndrome — an assessment of the present situation in the world: Memorandum from a WHO Meeting*

PubMed Central

1984-01-01

A consultative meeting was convened by the World Health Organization in Geneva on 22-25 November 1983 to assess the present situation of AIDS (the acquired immunodeficiency syndrome) in the world and to encourage collaboration between the different nations affected by this disease. AIDS was first reported in the USA in 1981, but probably existed there as early as 1978. Soon after its recognition in the USA, similar cases were identified in other areas of the world. In most western European countries and Canada, the epidemiological pattern is very similar to that in the United States, the majority of cases being in homosexual men. In other areas such as equatorial Africa and the Caribbean, the pattern seems to be different with no identifiable risk factors for the majority of cases. The disease is manifested by opportunistic infections and/or selected malignancies, with apparent differences in the clinical presentation between the cases in North America and Europe, on the one hand, and those in the tropics. To date there is no treatment that has significantly improved the underlying cellular immune deficiency, and the mortality is very high. The etiology of AIDS is unknown, but the epidemiological pattern is most consistent with its being caused by a transmissible agent; retroviruses come on top of the list of candidate agents. Despite the unknown etiology and the lack of laboratory diagnostic tests, sufficient information is available to permit health authorities to make recommendations that may reduce appreciably the incidence of the disease. AIDS is an important health problem in a number of countries and has international implications. Collaborative laboratory, epidemiological and clinical research between countries is needed to accelerate control efforts. In the meantime, WHO will coordinate exchange of information among countries. ImagesFig. 1 PMID:6331905

Personality, immune response and reproductive success: an appraisal of the pace-of-life syndrome hypothesis.

The pace-of-life syndrome (POLS) hypothesis is an extended concept of the life-history theory that includes behavioural traits. The studies challenging the POLS hypothesis often focus on the relationships between a single personality trait and a physiological and/or life-history trait. While pathogens represent a major selective pressure, few studies have been interested in testing relationships between behavioural syndrome, and several fitness components including immunity. The aim of this study was to address this question in the mealworm beetle, Tenebrio molitor, a model species in immunity studies. The personality score was estimated from a multidimensional syndrome based of four repeatable behavioural traits. In a first experiment, we investigated its relationship with two measures of fitness (reproduction and survival) and three components of the innate immunity (haemocyte concentration, and levels of activity of the phenoloxidase including the total proenzyme and the naturally activated one) to challenge the POLS hypothesis in T. molitor. Overall, we found a relationship between behavioural syndrome and reproductive success in this species, thus supporting the POLS hypothesis. We also showed a sex-specific relationship between behavioural syndrome and basal immune parameters. In a second experiment, we tested whether this observed relationship with innate immunity could be confirmed in term of differential survival after challenging by entomopathogenic bacteria, Bacillus thuringiensis. In this case, no significant relationship was evidenced. We recommend that future researchers on the POLS should control for differences in evolutionary trajectory between sexes and to pay attention to the choice of the proxy used, especially when looking at immune traits. © 2017 The Authors.

Immune deficiency in chronic rhinosinusitis: screening and treatment

PubMed Central

Chiarella, Sergio E.; Grammer, Leslie C.

2017-01-01

Introduction Chronic rhinosinusitis (CRS) is a prevalent disease with a high annual cost of treatment. Immune deficiencies are more common in individuals with CRS and should be especially considered in those patients who are refractory to medical and surgical therapy. Areas covered We performed a literature search in PubMed of the terms “immunodeficiency” and “sinusitis” or “rhinosinusitis” from 2006 through March 2016. All abstracts were reviewed to determine if they pertained to human disease; relevant articles were evaluated in their entirety and included in this review. Expert commentary CRS is a common disease; in those patients with frequent exacerbations or who are refractory to treatment, an immunodeficiency evaluation should be considered. Treatment includes vaccination, antibiotic therapy, immunoglobulin replacement and surgery. PMID:27500811

Obesity, insulin resistance, and related pathologies are associated with immune-mediated chronic inflammation. Kit mutant mice are protected from diet-induced obesity and associated co-morbidities, and this phenotype has previously been attributed to their lack of mast cells. We performed a comprehensive metabolic analysis of Kit-dependent Kit(W/Wv) and Kit-independent Cpa3(Cre/+) mast-cell-deficient mouse strains, employing diet-induced or genetic (Lep(Ob/Ob) background) models of obesity. Our results show that mast cell deficiency, in the absence of Kit mutations, plays no role in the regulation of weight gain or insulin resistance. Moreover, we provide evidence that the metabolic phenotype observed in Kit mutant mice, while independent of mast cells, is immune regulated. Our data underscore the value of definitive mast cell deficiency models to conclusively test the involvement of this enigmatic cell in immune-mediated pathologies and identify Kit as a key hematopoietic factor in the pathogenesis of metabolic syndrome.

Acquired Dyke-Davidoff-Masson syndrome, also known as hemispheric atrophy, is characterized by loss of volume of one cerebral hemisphere from an insult in early life. Crossed cerebellar diaschisis refers to dysfunction/atrophy of cerebellar hemisphere which is secondary to contralateral supratentorial insult. We describe magnetic resonance imaging findings in two cases of acquired Dyke-Davidoff-Masson syndrome with crossed cerebro-cerebellar diaschisis.

Leung, Anne K H; Ng, George W Y; Sin, K C; Au, S Y; Lai, K Y; Lee, K L; Law, K I

2015-04-01

We report a rare complication of factor V deficiency in a patient having Legionella pneumonia. This patient also had other complications like severe acute respiratory distress syndrome, acute kidney injury, and septic shock that required venous-venous extracorporeal membrane oxygenation support. This is the first reported case of acquired factor V deficiency in a patient receiving extracorporeal membrane oxygenation for Legionella pneumonia. With the combined use of intravenous immunoglobulin, rituximab and plasma exchange, we achieved rapid clearance of the factor V inhibitor within 1 week so as to allow safe decannulation of extracorporeal membrane oxygenation.

Biochemical and molecular analysis of an X-linked case of Leigh syndrome associated with thiamin-responsive pyruvate dehydrogenase deficiency.

1997-08-01

We report molecular analysis of thiamin-responsive pyruvate dehydrogenase complex (PDHC) deficiency in a patient with an X-linked form of Leigh syndrome. PDHC activity in cultured lymphoblastoid cells of this patient and his asymptomatic mother were normal in the presence of a high thiamin pyrophosphate (TPP) concentration (0.4 mmol/L). However, in the presence of a low concentration (1 x 10(-4) mmol/L) of TPP, the activity was significantly decreased, indicating that PDHC deficiency in this patient was due to decreased affinity of PDHC for TPP. The patient's older brother also was diagnosed as PDHC deficiency with Leigh syndrome, suggesting that PDHC deficiency in these two brothers was not a de novo mutation. Sequencing of the X-linked PDHC E1 alpha subunit revealed a C-->G point mutation at nucleotide 787, resulting in a substitution of glycine for arginine 263. Restriction enzyme analysis of the E1 alpha gene revealed that the mother was a heterozygote, indicating that thiamin-responsive PDHC deficiency associated with Leigh syndrome due to this mutation is transmitted by X-linked inheritance.

Salivary Defense Proteins: Their Network and Role in Innate and Acquired Oral Immunity

PubMed Central

Fábián, Tibor Károly; Hermann, Péter; Beck, Anita; Fejérdy, Pál; Fábián, Gábor

2012-01-01

There are numerous defense proteins present in the saliva. Although some of these molecules are present in rather low concentrations, their effects are additive and/or synergistic, resulting in an efficient molecular defense network of the oral cavity. Moreover, local concentrations of these proteins near the mucosal surfaces (mucosal transudate), periodontal sulcus (gingival crevicular fluid) and oral wounds and ulcers (transudate) may be much greater, and in many cases reinforced by immune and/or inflammatory reactions of the oral mucosa. Some defense proteins, like salivary immunoglobulins and salivary chaperokine HSP70/HSPAs (70 kDa heat shock proteins), are involved in both innate and acquired immunity. Cationic peptides and other defense proteins like lysozyme, bactericidal/permeability increasing protein (BPI), BPI-like proteins, PLUNC (palate lung and nasal epithelial clone) proteins, salivary amylase, cystatins, prolin-rich proteins, mucins, peroxidases, statherin and others are primarily responsible for innate immunity. In this paper, this complex system and function of the salivary defense proteins will be reviewed. PMID:22605979

2016-11-01

Thrombotic thrombocytopenic purpura is a rare thrombotic microangiopathy, related to a severe ADAMTS13 deficiency (a disintegrin and metalloprotease with thromboSpondin type 1 repeats, member 13; activity <10% of normal). Childhood-onset thrombotic thrombocytopenic purpura is very rare and initially often misdiagnosed, especially when ADAMTS13 deficiency is acquired (ie, not linked to inherited mutations of the ADAMTS13 gene). We aimed to investigate initial presentation, management, and outcome of acquired thrombotic thrombocytopenic purpura in children. Between Jan 1, 2000, and Dec 31, 2015, we studied a cohort of patients with child-onset and adolescent-onset acquired thrombotic thrombocytopenic purpura included in the French national registry for thrombotic microangiopathies at presentation and during follow up. The inclusion criteria were: first episode before age 18 years; ADAMTS13 activity less than 10% of normal at presentation; positive anti-ADAMTS13 autoantibodies during an episode, or a recovery of ADAMTS13 activity in remission, or both. ADAMTS13 activity and anti-ADAMTS13 autoantibodies were investigated by a central laboratory, and medical records were extensively reviewed to collect clinical and biological features with a standardised form. This study is registered with ClinicalTrials.gov, number NCT00426686. We enrolled 973 patients with childhood-onset thrombotic microangiopathy, of whom 74 had a severe ADAMTS13 deficiency (activity <10%) at presentation. 24 patients had an inherited thrombotic thrombocytopenic purpura also known as Upshaw-Schulman syndrome and five did not have follow-up data available, thus 45 children had acquired thrombotic thrombocytopenic purpura and were included in our database at presentation. 25 (56%) patients had idiopathic disease and 20 (44%) had miscellaneous associated clinical conditions. At diagnosis, median age was 13 years (IQR 7-16, range 4 months-17 years), with a sex ratio of 2·5 girls to 1 boy. Anti-ADAMTS13

Objectives The longer survival of patients with human immunodeficiency virus/acquired immunodeficiency syndrome and the introduction of the highly active antiretroviral therapy have increased the number of chronic conditions; among these, cardiovascular diseases. The aim of this study is to determine patient, disease, and factors associated with peripheral arterial disease in a population of patients with human immunodeficiency virus/acquired immunodeficiency syndrome. Methods A prospective nested case-control study of a cohort of patients with human immunodeficiency virus/acquired immunodeficiency syndrome was conducted in a tertiary medical center in Mexico City. A sample size of 206 patients was calculated. Medical history, relevant laboratory data, peripheral arterial exam, and screening ankle-brachial index tests were obtained. Results The prevalence of abnormal ankle-brachial indexes was 20% (42 patients). Patient's mean age was 44 years ±13. The majority (98.5%) were actively receiving highly active antiretroviral therapy; active smoking was reported in 55 (27%), arterial hypertension and type 2 diabetes mellitus were found in 24 (12%) and 22 (11%) patients. Median time from the human immunodeficiency virus diagnosis was eight years (Interquartile range ±11); the mean CD4 count was 481, with a mean viral load of 13,557 copies (SD ± 69025.27) and 1889.18 (SD ± 9052.77) for patients with normal and abnormal ankle-brachial index and a median of 40 (IQ ± 2). Viral load ( p = 0.04) and number of years with human immunodeficiency virus/acquired immunodeficiency syndrome ( p = 0.04) were significantly associated with abnormal ankle-brachial indexes. Conclusions Abnormal ankle-brachial index seems to be more frequent in Mexican patients with human immunodeficiency virus/acquired immunodeficiency syndrome when compared with the general population at the same age. The most important factors associated with arterial disease were the viral

Growth impairment in short stature homeobox-containing gene (SHOX) deficiency and Turner syndrome share a similar etiology. Because of the established effect of GH treatment on height in patients with Turner syndrome, we hypothesized that GH therapy would also stimulate growth in patients with SHOX deficiency. Our objectives were to evaluate long-term efficacy of GH treatment in short patients with SHOX deficiency and to compare the effect on final (adult) height (FH) in patients with SHOX deficiency and Turner syndrome. A prospective, multinational, open-label, randomized 3-arm study consisting of a 2-year control period and a subsequent extension period to FH. The treatment groups were 1) SHOX-D-C/GH (untreated during the control period, GH-treated during the extension), 2) SHOX-D-GH/GH, and 3) Turner-GH/GH (GH-treated during both study periods). Short-statured prepubertal patients with genetically confirmed SHOX deficiency (n = 49) or Turner syndrome (n = 24) who participated in the extension. Depending on the study arm, patients received a daily sc injection of 0.05 mg/kg recombinant human GH from start of the study or start of the extension until attainment of FH or study closure. Height SD score gain from start of GH treatment to FH was similar between the combined SHOX-deficient groups (n = 28, 1.34 ± 0.18 [least-squares mean ± SE]) and the Turner group (n = 19, 1.32 ± 0.22). In this FH population, 57% of the patients with SHOX deficiency and 32% of the patients with Turner syndrome achieved a FH greater than -2 SD score. GH treatment in short children with SHOX deficiency showed similar long-term efficacy as seen in girls with Turner syndrome.

Acquired pendular nystagmus

Acquired pendular nystagmus is comprised of quasi-sinusoidal oscillations of the eyes significantly affecting gaze holding and clarity of vision. The most common causes of acquired pendular nystagmus include demyelinating disorders such as multiple sclerosis and the syndrome of ocular palatal tremor. However, several other deficits, such as pharmacological intoxication, metabolic and genetic disorders, and granulomatous disorders can lead to syndromes mimicking acquired pendular nystagmus. Study of the kinematic features of acquired pendular nystagmus has suggested a putative pathophysiology of an otherwise mysterious neurological disorder. Here we review clinical features of neurological deficits that co-occur with acquired pendular nystagmus. Subsequent discussion of the pathophysiology of individual forms of pendular nystagmus speculates on mechanisms of the underlying disease while providing insights into pharmacotherapy of nystagmus.

Dental Space Deficiency Syndrome: An Anthropological Perspective.

PubMed

Richman, Colin S

2017-03-01

A new syndrome in dentistry, the dental space deficiency syndrome is proposed in this article. Signs and symptoms of this entity may include one or more of the following clinical dental features: tooth crowding, gingival recession, tooth impactions, rapid resorption of facial alveolar bony plates following premature tooth loss, dentally oriented sleep disorders, extended orthodontic treatment time, and malocclusion relapse following orthodontic therapy. These oral conditions, individually or collectively, seem to be associated with both genetic and functional factors. From an anthropological-functional perspective, the human jaws (basal bone and/or alveolar bone) have been shrinking. This results in a three-dimensional discrepancy between jawbone and tooth volumes, which are genetically determined. Consequently, the reduced volume of alveolar bone is not adequately able to accommodate the associated genetically determined dentition in functional and esthetic harmony. This paper describes the common etiology for the conditions listed above, namely the discrepancy between alveolar bone volume (essentially determined by functionality), and associated tooth volume (essentially determined by genetics), when considered in a three-dimensional perspective.

In endemic regions, visceral leishmaniasis is one of the most common opportunistic infections in HIV positive patients. Simultaneous infection with Leishmania and HIV has been reported in some countries but this is the first report of such a case in Iran. Our patient was a 27 years old man with intermittent night fever, abdominal pain, loss of appetite, vomiting, watery diarrhea and severe weight loss for 6 months. He had low socio-economic status with an imprisonment history. The patient was quite cachectic and had low grade fever. Physical exam and upper GI endoscopy revealed oropharyngeal candidiasis. Microscopic evaluation of duodenal biopsy material showed Leishmania amastigotes in macrophages of lamina propria. Leishman bodies were also observed in bone marrow aspiration specimen. Serologic tests were positive for Leishmania infantum. HIV antibody was also positive with a CD4+cell count of 80/μl. The diagnosis was acquired immunodeficiency syndrome with simultaneous visceral leishmaniasis involving intestinal mucosa.

A case with GAMT deficiency (homozygous c.64dupG mutation) presented with neurodevelopmental delay, rare seizures, behavioral disturbances, and mild hypotonia, posing diagnostic challenges. Metabolic investigations showed low creatinine in plasma and urine (guanidinoacetate couldn't be investigated) and slightly elevated lactate. MRI was normal. Correct diagnosis was possible only after MR spectroscopy was performed at age 5½ years. A homozygous c.64dupG mutation of the GAMT gene was identified in the proband. In conclusion, every case with neurodevelopmental delay or arrest, especially when accompanied by seizures, behavioral impairment, muscle hypotonia or extrapyramidal symptoms should undergo MRI with MR spectroscopy. Normal structural MRI doesn't exclude a creatine deficiency syndrome. Biochemical investigations of guanidinoacetate, creatine, and creatinine in body fluid should be done to diagnose cerebral creatine deficiency syndromes and to specify the deficient enzyme. Thus, a treatable disease will not be missed. © 2016 by the Association of Clinical Scientists, Inc.

Rhabdomyosarcoma in patients with constitutional mismatch-repair-deficiency syndrome.

Biallelic germline mutations in the mismatch repair genes MLH1, MSH2, MSH6 or PMS2 cause a recessive childhood cancer syndrome characterised by early-onset malignancies and signs reminiscent of neurofibromatosis type 1 (NF1). Alluding to the underlying genetic defect, we refer to this syndrome as constitutional mismatch repair-deficiency (CMMR-D) syndrome. The tumour spectrum of CMMR-D syndrome includes haematological neoplasias, brain tumours and Lynch syndrome-associated tumours. Other tumours, such as neuroblastoma, Wilm tumour, ovarian neuroectodermal tumour or infantile myofibromatosis, have so far been found only in individual cases. We analysed two consanguineous families that had members with suspected CMMR-D syndrome who developed rhabdomyosarcoma among other neoplasias. In the first family, we identified a pathogenic PMS2 mutation for which the affected patient was homozygous. In family 2, immunohistochemistry analysis showed isolated loss of PMS2 expression in all tumours in the affected patients, including rhabdomyosarcoma itself and the surrounding normal tissue. Together with the family history and microsatellite instability observed in one tumour this strongly suggests an underlying PMS2 alteration in family 2 also. Together, these two new cases show that rhabdomyosarcoma and possibly other embryonic tumours, such as neuroblastoma and Wilm tumour, belong to the tumour spectrum of CMMR-D syndrome. Given the clinical overlap of CMMR-D syndrome with NF1, we suggest careful examination of the family history in patients with embryonic tumours and signs of NF1 as well as analysis of the tumours for loss of one of the mismatch repair genes and microsatellite instability. Subsequent mutation analysis will lead to a definitive diagnosis of the underlying disorder.

Secondary IGF-I deficiency as a prognostic factor of growth hormone (GH) therapy effectiveness in children with isolated, non-acquired GH deficiency.

2015-04-01

Growth hormone (GH) deficiency (GHD) has recently been classified as secondary IGF-I deficiency but the significance of IGF-I measurement in diagnosing GHD is still discussed. The aim of the study was to assess the relationships between IGF-I secretion and GH therapy effectiveness in children with GHD. The analysis comprised 300 children with isolated, non-acquired GHD (GH peak below 10 μg/l) who completed GH therapy and attained final height (FH). In all patients IGF-I concentration was measured before the treatment and IGF-I deficiency was diagnosed if IGF-I SDS for age and sex was below -1.0. The following auxological indices were assessed: patients' height SDS before treatment (H₀SDS), FH SDS and improvement of FHSDS vs. H₀SDS (ΔHSDS). In the patients with IGF-I deficiency when compared with those with normal IGF-I secretion before treatment, significantly better FH SDS (-1.42±0.90 vs. -1.74±0.86, p=0.004) and ΔHSDS (1.64±1.01 vs. 1.32±1.05, p=0.010) were observed, despite similar H₀SDS (- 3.07±0.78 vs. - 3.11±0.77, p=0.63) and GH peak (7.0±3.1 μg/l vs. 6.8±2.1 μg/l, p=0.55). The patients who achieved FH over 10(th) centile had significantly lower IGF-I SDS before treatment than those with FH below 10(th) centile (- 1.59±1.54 vs. - 1.20±1.64, p=0.04), despite similar GH peak (7.0±2.3 μg/l vs. 6.7±3.1 μg/l, p=0.45). The patients with ΔHSDS over the median value had significantly lower IGF-I SDS than those with ΔHSDS below the median value (- 1.59±1.71 vs. - 1.09±1.47, p<0.0001), despite similar GH peak (6.8±2.5 μg/l vs. 7.0±2.7 μg/l, p=0.86). In children with isolated, non-acquired GHD, secondary IGF-I deficiency is an important predictor of better GH therapy effectiveness. © Georg Thieme Verlag KG Stuttgart · New York.

Acquired deficiency of tafazzin in the adult heart: Impact on mitochondrial function and response to cardiac injury.

The content and composition of cardiolipin (CL) is critical for preservation of mitochondrial oxidative phosphorylation (OXPHOS) and inner membrane integrity. Tafazzin (Taz) is an enzyme responsible for remodeling of immature CL containing mixed acyl groups into the mature tetralinoleyl form (C18:2)4-CL. We hypothesized that acquired defects in Taz in the mature heart would impact remodeling of CL and augment cardiac injury. The role of acquired Taz deficiency was studied using the inducible Taz knockdown (TazKD) mouse. Taz-specific shRNA is induced by doxycycline (DOX). One day of DOX intake decreased Taz mRNA in the heart to 20% vs. DOX-treated WT. Knockdown was initiated at an adult age and was stable during long term feeding. CL phenotype was assessed by (C18:2)4-CL content and was reduced 40% vs. WT at two months of DOX. TazKD showed increased production of reactive oxygen species and increased susceptibility to permeability transition pore opening at baseline. However, OXPHOS measured using the rate of oxygen consumption was unchanged in the setting of acquired Taz deficiency. Infarct size, measured in isolated buffer-perfused Langendorff hearts following 25min. Stop flow ischemia and 60min. Reperfusion was not altered in TazKD hearts. Thus, impaired Taz-function with onset at adult age does not enhance susceptibility to ischemia-reperfusion injury. Published by Elsevier B.V.

Parental vitamin deficiency affects the embryonic gene expression of immune-, lipid transport- and apolipoprotein genes

World Health Organization is concerned for parental vitamin deficiency and its effect on offspring health. This study examines the effect of a marginally dietary-induced parental one carbon (1-C) micronutrient deficiency on embryonic gene expression using zebrafish. Metabolic profiling revealed a reduced 1-C cycle efficiency in F0 generation. Parental deficiency reduced the fecundity and a total of 364 genes were differentially expressed in the F1 embryos. The upregulated genes (53%) in the deficient group were enriched in biological processes such as immune response and blood coagulation. Several genes encoding enzymes essential for the 1-C cycle and for lipid transport (especially apolipoproteins) were aberrantly expressed. We show that a parental diet deficient in micronutrients disturbs the expression in descendant embryos of genes associated with overall health, and result in inherited aberrations in the 1-C cycle and lipid metabolism. This emphasises the importance of parental micronutrient status for the health of the offspring.
