REVIEW
Aditya Kumar, Huned S Patwa, Richard J Nowak
Multifocal motor neuropathy (MMN) is a chronic immune-mediated disorder leading to slowly progressive muscle weakness and wasting. Current treatments are aimed at modulating the immune system in order to avoid further decline and to maintain functional status. Intravenous immunoglobulin (IVIg) is widely used in the treatment of immune-mediated disorders and is the only treatment approved for MMN. While patients do remain stable with maintenance IVIg treatment, most patients will slowly deteriorate over many years...

OBJECTIVE: Small fiber neuropathy commonly affects patients with sarcoidosis and is often refractory to standard immunosuppressive therapies used for systemic disease. The clinical features of sarcoidosis-associated small fiber neuropathy (SSFN) and its response to medical therapy have not been described in a large population. METHODS: We performed a retrospective review of patients with SSFN seen at the Cleveland Clinic over a 4-year period. RESULTS: SSFN was identified in 143 individuals although other causes of neuropathy were found in 28 cases...

REVIEW
Nichola Cooper
The management of patients with immune thrombocytopenia (ITP) is rapidly evolving. Over the last 15 years, a number of novel treatments have improved practice, with many steroid-sparing agents and a reduction in the progression to splenectomy. Although this has improved clinical care, many therapeutic challenges remain. There is no diagnostic test, no biomarkers to direct treatment and few comparative studies to help management decisions. Development of up to date guidelines is difficult with little high-grade evidence...

IVIg is used as an immunomodulatory agent in inflammatory disorders such as sepsis. IVIg also affects monocyte differentiation and functions, two processes in which microRNAs play a crucial role. Monocytes detect microorganisms through pathogen recognition receptors (PRRs) such as TLR4. MiR-146a has been shown to supress NF-κB and IRF3 activity, two key components of TLR4 signaling. To evaluate whether miR-146a is involved in the anti-inflammatory effects of IVIg, monocytes were treated with LPS or IVIg alone or, alternately, first activated with LPS followed by washing and addition of IVIg...

PURPOSE: Because immune mediated mechanisms are suspected in epileptogenesis, IVIg and corticosteroids have been used as alternatives to treat refractory seizures. We present our experience treating intractable epileptic children with IVIg and prednisone. METHODS: Children with intractable epilepsy treated with prednisone or IVIg between 2005-2016 were reviewed retrospectively. Children with infantile spasms and autoimmune epilepsy were excluded. Data analyzed include epilepsy type and etiology, duration of epilepsy prior to treatment, seizure outcome, time to best seizure outcome, and adverse effects...

Viral infections represent significant morbidity and mortality factors in kidney transplant recipients, with CMV, EBV, and BKV infections being most common. Desensitization (DES) with IVIg and rituximab with/without plasma exchange followed by kidney transplantation with alemtuzumab induction increased successful transplant rates in HLA-sensitized patients but may represent an increased risk for viral infections due to severe lymphocyte depletion. Here, we report on the posttransplant viral infection status in 372 DES versus 538 non-DES patients...

Throughout the past years we stepwise modified our immunosuppressive treatment regimen for patients with antibody-mediated rejection (ABMR). Here, we describe three consecutive groups treated with different regimens. From 2005 until 2008, we treated all patients with biopsy-proven ABMR with rituximab (500 mg), low-dose (30 g) intravenous immunoglobulins (IVIG), and plasmapheresis (PPH, 6x) (group RLP, n = 12). Between 2009 and June 2010, patients received bortezomib (1.3 mg/m(2), 4x) together with low-dose IVIG and PPH (group BLP, n = 11)...

Pregnancy with Rh isoimmunization is a grave situation. Two women with indirect Coombs test (ICT) positive were managed conservatively with a favorable outcome. Peak systolic velocity (PSV) of middle cerebral artery (MCA) was measured every 2 weeks, and pregnancy continued till the value remained <1.5 mean of median. In one woman, the pregnancy could be prolonged to 37 weeks when delivery was induced and the neonate did not develop hyperbilirubinemia. In the second woman with bad obstetric history, when a highly positive ICT was reported, intravenous immunoglobulin (IVIG) was given in a single dose of 5 g every 2 weeks starting at 27 weeks, for a total of three doses, along with measurement of PSV of MCA...

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease and elderly people living in rural areas have the greatest risk of infection. We report the first pediatric case of SFTS in Korea and the clinical characteristics and disease progression in children. A 10-year-old child from Chonnam province visited the hospital with myalgia and a history of fever over the previous 8 days. Her father noticed a tick on her head and removed it before fever developed. Because the symptoms continued, her father consulted the community health center and SFTS virus was detected both from the tick (Haemaphysalis longicornis) and the patient's blood...

PROBLEM: Fetal and neonatal alloimmune thrombocytopenia is an alloimmune disorder resulting from platelet opsonization by maternal antibodies that destroy fetal platelets. As there is no antenatal screening or immunization to prevent sensitization, selection of high-risk population or the prevention of antenatal sensitization is significantly limited. METHOD OF STUDY: (i) A case report of ante- and postnatal management of a woman with paternal homozygosity for human platelet antigen-1(HPA) incompatibility...

BACKGROUND: Immune checkpoint inhibitors, including antibodies against programmed death 1 (PD-1) and cytotoxic T-lymphocyte antigen 4 (CTLA-4), are being used with increasing frequency for the treatment of cancer. Immune-related adverse events (irAEs) including colitis, dermatitis, and pneumonitis are well described, but less frequent events are now emerging with larger numbers of patients treated. Herein we describe the incidence and spectrum of thrombocytopenia following immune checkpoint inhibitor therapy and two severe cases of idiopathic thrombocytopenic purpura (ITP)...

Intravenous immunoglobulin (IVIg) preparations are being investigated as a potential agent for treatment or prevention of Alzheimer's disease (AD). Antibodies towards soluble β-amyloid (Aβ) contained in IVIg were considered to be the major component contributing to the beneficial effect of the preparations in pilot studies. This study compared the antibody concentrations against Aβ in Octagam(®) IVIg (Octapharma) and 9 IVIg preparations from different Chinese manufacturers by ELISA, using Aβ40 monomer, Aβ40 soluble oligomers, Aβ42 monomer and Aβ42 soluble oligomers as the antigens...
