Autosomal Dominant Hyper-IgE Syndrome in the USIDNET Registry.

BACKGROUND: Autosomal dominant hyper-IgE syndrome (AD-HIES) is a rare condition. OBJECTIVE: Data from the USIDNET Registry provide a resource to examine the characteristics of patients with rare immune deficiency diseases. METHODS: A query was submitted to the USIDNET requesting deidentified data for patients with physician-diagnosed AD-HIES through July 2016. RESULTS: Data on 85 patients diagnosed with AD-HIES (50 males; 35 females) born between 1950 and 2013, collected by 14 physicians from 25 states and Quebec, were entered into the USIDNET Registry by July 2016. Cumulative follow-up was 2157 years. Of these patients, 45.9% had a family history of HIES. The complications reported included skin abscesses (74.4%), eczema (57.7%), retained primary teeth (41.4%), fractures (39%), scoliosis (34.1%), and cancer (7%). Reported allergic diseases included food (37.8%), environmental (18%), and drugs (42.7%). The mean serum IgE level was 8383.7 kU/mL and was inversely correlated to the patient's age. A total of 49.4% had eosinophilia; 56% were known to be on trimethoprim-sulfamethoxazole, 26.6% on antifungal coverage, and 30.6% on immunoglobulin replacement therapy. Pneumonias were more commonly attributed to Staphylococcus aureus (55.3%) or Aspergillus fumigatus (22.4%); 19.5% had a history of lung abscess; these were most often associated with Pseudomonas aeruginosa (P Fisher's exact test = .029) or A. fumigatus (P Fisher's exact test = .016). Lung abscesses were significantly associated with drug reactions (P χ2 = .01; odds ratio: 4.03 [1.2-12.97]), depression (P Fisher's exact test = .036), and lower Karnofsky index scores (P Mann-Whitney = .007). DISCUSSION: Data from the USIDNET Registry summarize the currently reported clinical characteristics of a large cohort of subjects with AD-HIES.

Ophthalmic manifestations of perinatally acquired HIV in a US cohort of long-term survivors.

BACKGROUND/AIMS: To determine the ophthalmic manifestations of HIV in a cohort of long-term survivors of perinatally acquired HIV. METHODS: Twenty-two patients with perinatally acquired HIV who were aged ≥12 years were prospectively studied at a university clinic. They underwent complete ophthalmic examinations and fundus photography. Their medical histories, medications and CD4 counts were abstracted from the medical records. To evaluate for keratoconjunctivitis sicca, both HIV patients and 44 healthy controls (matched by age, gender and contact lens wear) underwent Schirmer testing and ocular surface staining. RESULTS: Nine male and 13 female HIV patients with mean age of 16.6 years (SD, 3.4) were examined. Of the 22 HIV patients, 21 had been treated with highly active antiretroviral therapy (HAART). Only one patient had a CD4 count nadir of <200 cells/µL. The mean visual acuity of the eyes of the HIV subjects was 20/22 (SD, 1.6 lines). No patient had cytomegalovirus retinitis. Four of the 22 (18%) HIV patients had strabismus. HIV subjects and controls had similar rates of abnormal Schirmer (9% and 14%, p=0.62) and ocular staining scores (p=0.29). CONCLUSIONS: In the post-HAART era, long-term survivors of perinatally acquired HIV exhibited little vision-threatening disease, but had a high prevalence of strabismus.

Persistent systemic inflammation and atypical enterocolitis in patients with NEMO syndrome.

The NEMO syndrome is a primary immunodeficiency with immune and non-immune manifestations. The immune deficiency is heterogeneous showing defects in humoral, innate, and cell-mediated immunity. While the clinical aspects of the immunodeficiency are increasingly well understood, little is known about autoimmune manifestations in NEMO patients. We therefore sought to examine serologic markers of systemic inflammation and intestinal pathology in a kindred of patients with the NEMO syndrome. We observed persistent elevation of erythrocyte sedimentation rates in five patients, and two were symptomatic, with a chronic but atypical enterocolitis. Though pathologic lesions in these two patients were consistent with acute inflammation, sustained clinical improvement was only achieved with systemic and/or topical glucocorticoid therapy. Our data suggest that some patients with the NEMO syndrome exhibit persistent elevation of inflammatory markers similar to systemic autoimmune diseases and may subsequently develop an atypical enterocolitis.
