BACKGROUND Isolated congenital asplenia is a poorly understood and rare form of primary immunodeficiency, often associated with life-threatening infections. CASE REPORT We encountered a unique case of a 22-year-old asplenic male who presented with severe iron-deficiency anemia secondary to occult gastrointestinal bleeding since age 15. Our extensive work-up confirmed jejunal arteriovenous malformations as the source of the bleed. Six months after the treatment, the patient has reported no further episodes of gastrointestinal bleeding and his hemoglobin has remained stable...

PURPOSE OF REVIEW: Overview of neuroendocrine neoplasms in the context of their associations with primary and secondary immunodeficiency states. RECENT FINDINGS: Malignancies of neuroendocrine origin are well known to be associated with hereditary syndromes, including multiple endocrine neoplasia type 1, von Hippel-Lindau syndrome, neurofibromatosis type 1, and tuberous sclerosis. This review includes the X-linked form of hyper-IgM syndrome (XHIGM), due to mutations in the CD40Ligand gene (CD40LG), as an additional inherited disorder with susceptibility to such malignancies, and discusses neuroendocrine tumors (NETs) arising in other immunocompromised states...

REVIEW
Michael Garshick, James A Underberg
PURPOSE OF REVIEW: Many guidelines exist for the use of statins in the primary prevention of atherosclerotic cardiovascular disease (ASCVD). Few have focused on disease specific states that predispose to ASCVD. This review is intended to focus on the recommendations and evidence in inflammatory diseases that predispose to an increased risk of ASCVD beyond what conventional cardiac risk scores would predict. RECENT FINDINGS: Certain autoimmune inflammatory diseases such as rheumatoid arthritis (RA), systemic lupus erythematous (SLE), and psoriasis/psoriatic arthritis have all been shown to increase the risk of ASCVD...

Natural killer (NK) cells play an essential role in antiviral immunity, but knowledge of their function in secondary lymphoid organs is incomplete. Lymph node follicles constitute a major viral reservoir during infections with HIV-1 and simian immunodeficiency virus of macaques (SIVmac). In contrast, during nonpathogenic infection with SIV from African green monkeys (SIVagm), follicles remain generally virus free. We show that NK cells in secondary lymphoid organs from chronically SIVagm-infected African green monkeys (AGMs) were frequently CXCR5(+) and entered and persisted in lymph node follicles throughout the follow-up (240 d post-infection)...

Exclusive Breastfeeding (EBF) among human immunodeficiency virus (HIV)-infected mothers is known to be associated with a sustained and significant reduction in HIV transmission and has the potential to reduce infant and under-five mortality. Research shows that EBF is not common in many HIV-endemic, resource-limited settings despite recommendations by the World Health Organization. Although evidence abounds that male partner involvement increases HIV testing and uptake and retention of prevention of mother-to-child transmission interventions, few studies have evaluated the impact of male partners' involvement and decision-making on initiation, maintenance, and sustainment of EBF...

Background: East Africa, where Leishmania donovani is prevalent, faces the highest burden world-wide of visceral leishmaniasis (VL) and human immunodeficiency virus (HIV) coinfection. However, data on the risk and predictors of VL relapse are scarce. Such information is vital to target medical follow-up and interventions to those at highest risk. Methods: We conducted a retrospective cohort study at a Médecins Sans Frontières-supported health center in northwest Ethiopia...

Background: Ocular syphilis is an inflammatory eye disease due to Treponema pallidum infection. In the United States, syphilis rates have increased since 2000; clusters of ocular syphilis were reported in 2015. We investigated ocular syphilis in North Carolina to describe the epidemiology and clinical course of disease. Methods: We reviewed syphilis cases reported to North Carolina during 2014-2015 and abstracted information from health department interviews for cases with ocular symptoms and no other defined etiology...

In an Egyptian girl born to consanguineous parents, whole-exome sequencing (WES) identified a homozygous mutation in PHGDH, c.1273G>A (p.Val425Met), indicating 3-phosphoglycerate dehydrogenase deficiency. This diagnosis was compatible with the patient's microcephaly, severe psychomotor retardation, seizures and cataracts. However, she additionally suffered from recurrent (at least monthly) episodes of prolonged and severe chest infections requiring hospitalization, suggesting a secondary, predisposing and potentially Mendelian, condition...

Secondary syphilis (SS) has always been puzzling for the clinicians because of the similarity of the appearance of skin rashes with other dermatoses. Serological assays are useful, but less sensitive at an early stage of SS or when patients are immunodeficient. Therefore, there is an urgent need to develop a rapid and effective tool for the diagnosis of SS, which may play an important role in the control of epidemic syphilis outbreaks. In this study, we evaluated a loop-mediated isothermal amplification (LAMP) assay, targeting gene encoding the basic membrane protein of Treponema pallidum, to detect the presence of circulating T...

Follicular helper T cells (Tfh) have been discovered in lymph nodes and, since then, are the focus of very intensive research to understand their origin, differentiation and functions. Tfh interact with B cells in the secondary lymphoid organs leading to B cell differentiation and maturation. Tfh are particularly studied in pathological contexts such as autoimmune diseases and infection by the human immunodeficiency virus (HIV). In the context of HIV infection, broadly neutralizing antibodies have been identified in a few patients...

HIV-related immunodeficiency has complex effects on female genital HPV, which include increased risks of infection, multiple types, persistence, reactivation and the risk to develop pre-invasive and invasive disease. Reconstitution of immunity with anti-viral drugs improves cellular immunity, but the risk of HPV-related malignancy remains higher than background incidences and presents at younger ages. Early initiation of antiretroviral therapy (ART) allows improved retention of immune memory through existing antibodies and T-cell clones and improves long-term outcomes...

Ritonavir is commonly used in low doses to boost plasma levels of protease inhibitors in patients with human immunodeficiency virus (HIV) infections. It is also a potent inhibitor of cytochrome P450. We present a 50-year-old African American male with past medical history of HIV on highly active antiretroviral therapy (HAART), which also included ritonavir and long standing asthma that has been treated with inhaled fluticasone, who presented with back pain. He had central obesity, prominent abdominal striae and wasted extremities on physical examination...

PURPOSE: Over a third of patients with common variable immunodeficiency (CVID) suffer from secondary complications like inflammatory organ disease, autoimmune manifestations, or lymphoproliferation contributing to increased morbidity and mortality in affected patients. Innate lymphoid cells (ILCs) have emerging roles in setting the milieu for physiological, but also pathological, immune responses and inflammation. We therefore sought to correlate the recently identified disturbed homeostasis of ILCs with alterations of the adaptive immune system in complex CVID patients (CVIDc)...

BACKGROUND: Acute respiratory failure (ARF) is still one of the most severe complications in immunocompromised patients. Our previous systematic review showed noninvasive mechanical ventilation (NIV) reduced mortality, length of hospitalization and ICU stay in AIDS/hematological malignancy patients with relatively less severe ARF, compared to invasive mechanical ventilation (IMV). However, this systematic review was based on 13 observational studies and the quality of evidence was low to moderate...

Despite extensive characterization of the human immunodeficiency virus type 1 (HIV-1) hydrophobic fusion peptide (FP), the structure-function relationships underlying its extraordinary degree of conservation remain poorly understood. Specifically, the fact that the tandem repeat of the FLGFLG tripeptide is absolutely conserved suggests that high hydrophobicity may not suffice to unleash FP function. Here, we have compared the nuclear magnetic resonance (NMR) structures adopted in nonpolar media by two FP surrogates, wtFP-tag and scrFP-tag, which had equal hydrophobicity but contained wild-type and scrambled core sequences LFLGFLG and FGLLGFL, respectively...
