Temporal shifts in the skin microbiome associated with disease flares and treatment in children with atopic dermatitis.

Atopic dermatitis (AD) has long been associated with Staphylococcus aureus skin colonization or infection and is typically managed with regimens that include antimicrobial therapies. However, the role of microbial communities in the pathogenesis of AD is incompletely characterized. To assess the relationship between skin microbiota and disease progression, 16S ribosomal RNA bacterial gene sequencing was performed on DNA obtained directly from serial skin sampling of children with AD. The composition of bacterial communities was analyzed during AD disease states to identify characteristics associated with AD flares and improvement post-treatment. We found that microbial community structures at sites of disease predilection were dramatically different in AD patients compared with controls. Microbial diversity during AD flares was dependent on the presence or absence of recent AD treatments, with even intermittent treatment linked to greater bacterial diversity than no recent treatment. Treatment-associated changes in skin bacterial diversity suggest that AD treatments diversify skin bacteria preceding improvements in disease activity. In AD, the proportion of Staphylococcus sequences, particularly S. aureus, was greater during disease flares than at baseline or post-treatment, and correlated with worsened disease severity. Representation of the skin commensal S. epidermidis also significantly increased during flares. Increases in Streptococcus, Propionibacterium, and Corynebacterium species were observed following therapy. These findings reveal linkages between microbial communities and inflammatory diseases such as AD, and demonstrate that as compared with culture-based studies, higher resolution examination of microbiota associated with human disease provides novel insights into global shifts of bacteria relevant to disease progression and treatment.

Novel assessment tools to evaluate clinical and laboratory responses in a subset of patients enrolled in the Rituximab in Myositis trial.

OBJECTIVES: We aimed to assess changes in myositis core set measures and ancillary clinical and laboratory data from the National Institutes of Health's subset of patients enrolled in the Rituximab in Myositis trial. METHODS: Eighteen patients (5 dermatomyositis, 8 polymyositis, 5 juvenile dermatomyositis) completed more in-depth testing of muscle strength and cutaneous assessments, patient-reported outcomes, and laboratory tests before and after administration of rituximab. Percentage change in individual measures and in the definitions of improvement (DOIs) and standardized response means were examined over 44 weeks. RESULTS: Core set activity measures improved by 18-70% from weeks 0-44 and were sensitive to change. Fifteen patients met the DOI at week 44, 9 patients met a DOI 50% response, and 4 met a DOI 70% response. Muscle strength and function measures were more sensitive to change than cutaneous assessments. Constitutional, gastrointestinal, and pulmonary systems improved 44-70%. Patient-reported outcomes improved up to 28%. CD20+ B cells were depleted in the periphery, but B cell depletion was not associated with clinical improvement at week 16. CONCLUSIONS: This subset of patients had high rates of clinical response to rituximab, similar to patients in the overall trial. Most measures were responsive, and muscle strength had a greater degree of change than cutaneous assessments. Several novel assessment tools, including measures of strength and function, extra-muscular organ activity, fatigue, and health-related quality of life, are promising for use in future myositis trials. Further study of B cell-depleting therapies in myositis, particularly in treatment-naïve patients, is warranted.

Brief report: genotype, phenotype, and clinical course in five patients with PAPA syndrome (pyogenic sterile arthritis, pyoderma gangrenosum, and acne).

OBJECTIVE: To describe the genotypes, phenotypes, immunophenotypes, and treatments of PAPA syndrome (pyogenic sterile arthritis, pyoderma gangrenosum, and acne), a rare autoinflammatory disease, in 5 patients. METHODS: Clinical information was gathered from medical records and through interviews with 5 patients from 4 kindreds. PSTPIP1 (CD2BP1) exon 10 and exon 11 sequencing was performed in each patient. Neutrophil granule content and cytokine levels were determined in plasma and stimulated peripheral blood mononuclear cells (PBMCs) from patients and controls. RESULTS: We identified 2 previously described PAPA syndrome-associated PSTPIP1 mutations, A230T and E250Q, and a novel change, E250K. Disease penetrance was incomplete, with variable expressivity. The cutaneous manifestations included pathergy, cystic acne, and pyoderma gangrenosum. Interleukin-1ß (IL-1ß) and circulating neutrophil granule enzyme levels were markedly elevated in patients compared to those in controls. PBMC stimulation studies demonstrated impaired production of IL-10 and enhanced production of granulocyte-macrophage colony-stimulating factor. Good resolution of pyoderma gangrenosum was achieved in 3 patients with tumor necrosis factor α (TNFα) blockade treatment. CONCLUSION: This analysis of 5 patients demonstrates that mutations in PSTPIP1 are incompletely penetrant and variably expressed in the PAPA syndrome. Neutrophil granule proteins are markedly elevated ex vivo and in the plasma, and elevated levels might be compatible with a diagnosis of PAPA syndrome. TNFα blockade appears to be effective in treating the cutaneous manifestations of PAPA syndrome.

Combined immunodeficiency associated with DOCK8 mutations.

BACKGROUND: Recurrent sinopulmonary and cutaneous viral infections with elevated serum levels of IgE are features of some variants of combined immunodeficiency. The genetic causes of these variants are unknown. METHODS: We collected longitudinal clinical data on 11 patients from eight families who had recurrent sinopulmonary and cutaneous viral infections. We performed comparative genomic hybridization arrays and targeted gene sequencing. Variants with predicted loss-of-expression mutations were confirmed by means of a quantitative reverse-transcriptase-polymerase-chain-reaction assay and immunoblotting. We evaluated the number and function of lymphocytes with the use of in vitro assays and flow cytometry. RESULTS: Patients had recurrent otitis media, sinusitis, and pneumonias; recurrent Staphylococcus aureus skin infections with otitis externa; recurrent, severe herpes simplex virus or herpes zoster infections; extensive and persistent infections with molluscum contagiosum; and human papillomavirus infections. Most patients had severe atopy with anaphylaxis; several had squamous-cell carcinomas, and one had T-cell lymphoma-leukemia. Elevated serum IgE levels, hypereosinophilia, low numbers of T cells and B cells, low serum IgM levels, and variable IgG antibody responses were common. Expansion in vitro of activated CD8 T cells was impaired. Novel homozygous or compound heterozygous deletions and point mutations in the gene encoding the dedicator of cytokinesis 8 protein (DOCK8) led to the absence of DOCK8 protein in lymphocytes. CONCLUSIONS: Autosomal recessive DOCK8 deficiency is associated with a novel variant of combined immunodeficiency.

An autoinflammatory disease with deficiency of the interleukin-1-receptor antagonist.

BACKGROUND: Autoinflammatory diseases manifest inflammation without evidence of infection, high-titer autoantibodies, or autoreactive T cells. We report a disorder caused by mutations of IL1RN, which encodes the interleukin-1-receptor antagonist, with prominent involvement of skin and bone. METHODS: We studied nine children from six families who had neonatal onset of sterile multifocal osteomyelitis, periostitis, and pustulosis. Response to empirical treatment with the recombinant interleukin-1-receptor antagonist anakinra in the first patient prompted us to test for the presence of mutations and changes in proteins and their function in interleukin-1-pathway genes including IL1RN. RESULTS: We identified homozygous mutations of IL1RN in nine affected children, from one family from Newfoundland, Canada, three families from The Netherlands, and one consanguineous family from Lebanon. A nonconsanguineous patient from Puerto Rico was homozygous for a genomic deletion that includes IL1RN and five other interleukin-1-family members. At least three of the mutations are founder mutations; heterozygous carriers were asymptomatic, with no cytokine abnormalities in vitro. The IL1RN mutations resulted in a truncated protein that is not secreted, thereby rendering cells hyperresponsive to interleukin-1beta stimulation. Patients treated with anakinra responded rapidly. CONCLUSIONS: We propose the term deficiency of the interleukin-1-receptor antagonist, or DIRA, to denote this autosomal recessive autoinflammatory disease caused by mutations affecting IL1RN. The absence of interleukin-1-receptor antagonist allows unopposed action of interleukin-1, resulting in life-threatening systemic inflammation with skin and bone involvement.

Autosomal dominant and sporadic monocytopenia with susceptibility to mycobacteria, fungi, papillomaviruses, and myelodysplasia.

We identified 18 patients with the distinct clinical phenotype of susceptibility to disseminated nontuberculous mycobacterial infections, viral infections, especially with human papillomaviruses, and fungal infections, primarily histoplasmosis, and molds. This syndrome typically had its onset in adulthood (age range, 7-60 years; mean, 31.1 years; median, 32 years) and was characterized by profound circulating monocytopenia (mean, 13.3 cells/microL; median, 14.5 cells/microL), B lymphocytopenia (mean, 9.4 cells/microL; median, 4 cells/microL), and NK lymphocytopenia (mean, 16 cells/microL; median, 5.5 cells/microL). T lymphocytes were variably affected. Despite these peripheral cytopenias, all patients had macrophages and plasma cells at sites of inflammation and normal immunoglobulin levels. Ten of these patients developed 1 or more of the following malignancies: 9 myelodysplasia/leukemia, 1 vulvar carcinoma and metastatic melanoma, 1 cervical carcinoma, 1 Bowen disease of the vulva, and 1 multiple Epstein-Barr virus(+) leiomyosarcoma. Five patients developed pulmonary alveolar proteinosis without mutations in the granulocyte-macrophage colony-stimulating factor receptor or anti-granulocyte-macrophage colony-stimulating factor autoantibodies. Among these 18 patients, 5 families had 2 generations affected, suggesting autosomal dominant transmission as well as sporadic cases. This novel clinical syndrome links susceptibility to mycobacterial, viral, and fungal infections with malignancy and can be transmitted in an autosomal dominant pattern.

Mutations in a novel gene lead to kidney tumors, lung wall defects, and benign tumors of the hair follicle in patients with the Birt-Hogg-Dubé syndrome.

Birt-Hogg-Dubé (BHD) syndrome is a rare inherited genodermatosis characterized by hair follicle hamartomas, kidney tumors, and spontaneous pneumothorax. Recombination mapping in BHD families delineated the susceptibility locus to 700 kb on chromosome 17p11.2. Protein-truncating mutations were identified in a novel candidate gene in a panel of BHD families, with a 44% frequency of insertion/deletion mutations within a hypermutable C(8) tract. Tissue expression of the 3.8 kb transcript was widespread, including kidney, lung, and skin. The full-length BHD sequence predicted a novel protein, folliculin, that was highly conserved across species. Discovery of disease-causing mutations in BHD, a novel kidney cancer gene associated with renal oncocytoma or chromophobe renal cancer, will contribute to understanding the role of folliculin in pathways common to skin, lung, and kidney development.

A multicenter pilot evaluation of the National Institutes of Health chronic graft-versus-host disease (cGVHD) therapeutic response measures: feasibility, interrater reliability, and minimum detectable change.

The lack of standardized criteria for measuring therapeutic response is a major obstacle to the development of new therapeutic agents for chronic graft-versus-host disease (cGVHD). National Institutes of Health (NIH) consensus criteria for evaluating therapeutic response were published in 2006. We report the results of 4 consecutive pilot trials evaluating the feasibility and estimating the interrater reliability and minimum detectable change of these response criteria. Hematology-oncology clinicians with limited experience in applying the NIH cGVHD response criteria (n = 34) participated in a 2.5-hour training session on response evaluation in cGVHD. Feasibility and interrater reliability between subspecialty cGVHD experts and this panel of clinician raters were examined in a sample of 25 children and adults with cGVHD. The minimum detectable change was calculated using the standard error of measurement. Clinicians' impressions of the brief training session, the photo atlas, and the response criteria documentation tools were generally favorable. Performing and documenting the full set of response evaluations required a median of 21 minutes (range: 12-60 minutes) per rater. The Schirmer tear test required the greatest time of any single test (median: 9 minutes). Overall, interrater agreement for skin and oral manifestations was modest; however, in the third and fourth trials, the agreement between clinicians and experts for all dimensions except movable sclerosis approached satisfactory values. In the final 2 trials, the threshold for defining change exceeding measurement error was 19% to 22% body surface area (BSA) for erythema, 18% to 26% BSA for movable sclerosis, 17% to 21% BSA for nonmovable sclerosis, and 2.1 to 2.6 points on the 15-point NIH Oral cGHVD scale. Agreement between clinician-expert pairs was moderate to substantial for the measures of functional capacity and for the gastrointestinal and global cGVHD rating scales. These results suggest that the NIH response criteria are feasible for use, and these reliability estimates are encouraging, because they were observed following a single 2.5-hour training session given at multiple transplant centers, with no opportunity for iterative training and calibration. Research is needed to evaluate inter- and intrarater reliability in larger samples, and to evaluate these response criteria as predictors of outcomes in clinical trials.

Phenotype and course of Hutchinson-Gilford progeria syndrome.

BACKGROUND: Hutchinson-Gilford progeria syndrome is a rare, sporadic, autosomal dominant syndrome that involves premature aging, generally leading to death at approximately 13 years of age due to myocardial infarction or stroke. The genetic basis of most cases of this syndrome is a change from glycine GGC to glycine GGT in codon 608 of the lamin A (LMNA) gene, which activates a cryptic splice donor site to produce abnormal lamin A; this disrupts the nuclear membrane and alters transcription. METHODS: We enrolled 15 children between 1 and 17 years of age, representing nearly half of the world's known patients with Hutchinson-Gilford progeria syndrome, in a comprehensive clinical protocol between February 2005 and May 2006. RESULTS: Clinical investigations confirmed sclerotic skin, joint contractures, bone abnormalities, alopecia, and growth impairment in all 15 patients; cardiovascular and central nervous system sequelae were also documented. Previously unrecognized findings included prolonged prothrombin times, elevated platelet counts and serum phosphorus levels, measured reductions in joint range of motion, low-frequency conductive hearing loss, and functional oral deficits. Growth impairment was not related to inadequate nutrition, insulin unresponsiveness, or growth hormone deficiency. Growth hormone treatment in a few patients increased height growth by 10% and weight growth by 50%. Cardiovascular studies revealed diminishing vascular function with age, including elevated blood pressure, reduced vascular compliance, decreased ankle-brachial indexes, and adventitial thickening. CONCLUSIONS: Establishing the detailed phenotype of Hutchinson-Gilford progeria syndrome is important because advances in understanding this syndrome may offer insight into normal aging. Abnormal lamin A (progerin) appears to accumulate with aging in normal cells. (ClinicalTrials.gov number, NCT00094393.)

STAT3 mutations in the hyper-IgE syndrome.

BACKGROUND: The hyper-IgE syndrome (or Job's syndrome) is a rare disorder of immunity and connective tissue characterized by dermatitis, boils, cyst-forming pneumonias, elevated serum IgE levels, retained primary dentition, and bone abnormalities. Inheritance is autosomal dominant; sporadic cases are also found. METHODS: We collected longitudinal clinical data on patients with the hyper-IgE syndrome and their families and assayed the levels of cytokines secreted by stimulated leukocytes and the gene expression in resting and stimulated cells. These data implicated the signal transducer and activator of transcription 3 gene (STAT3) as a candidate gene, which we then sequenced. RESULTS: We found increased levels of proinflammatory gene transcripts in unstimulated peripheral-blood neutrophils and mononuclear cells from patients with the hyper-IgE syndrome, as compared with levels in control cells. In vitro cultures of mononuclear cells from patients that were stimulated with lipopolysaccharide, with or without interferon-gamma, had higher tumor necrosis factor alpha levels than did identically treated cells from unaffected persons (P=0.003). In contrast, the cells from patients with the hyper-IgE syndrome generated lower levels of monocyte chemoattractant protein 1 in response to the presence of interleukin-6 (P=0.03), suggesting a defect in interleukin-6 signaling through its downstream mediators, one of which is STAT3. We identified missense mutations and single-codon in-frame deletions in STAT3 in 50 familial and sporadic cases of the hyper-IgE syndrome. Eighteen discrete mutations, five of which were hot spots, were predicted to directly affect the DNA-binding and SRC homology 2 (SH2) domains. CONCLUSIONS: Mutations in STAT3 underlie sporadic and dominant forms of the hyper-IgE syndrome, an immunodeficiency syndrome involving increased innate immune response, recurrent infections, and complex somatic features.

Chronic phototoxicity and aggressive squamous cell carcinoma of the skin in children and adults during treatment with voriconazole.

BACKGROUND: Voriconazole is a broad-spectrum antifungal agent associated with photosensitivity and accelerated photoaging. A possible link with aggressive squamous cell carcinoma (SCC) has also been reported. OBJECTIVE: We sought to determine the incidence and frequency of cutaneous SCC among patients undergoing long-term treatment with voriconazole who also manifest features of chronic phototoxicity. METHODS: We conducted a retrospective review of patients who developed one or more squamous cell neoplasms during long-term treatment with voriconazole at 3 academic dermatology centers. RESULTS: A total of 51 cutaneous SCC were identified in 8 patients (median age 34.5 years, range 9-54) treated with chronic voriconazole (median duration 46.5 months, range 13-60). Underlying diagnoses included graft-versus-host disease, HIV, and Wegener granulomatosis. Signs of chronic phototoxicity and accelerated photoaging included erythema, actinic keratoses, and lentigo formation. LIMITATIONS: The retrospective nature of the study cannot determine the true population risk of SCC associated with voriconazole therapy. A prospective cohort study is needed. CONCLUSION: A high index of suspicion for photosensitivity and SCC may be warranted with chronic voriconazole use when used in the setting of concurrent immunosuppression.

Hand-foot skin reaction increases with cumulative sorafenib dose and with combination anti-vascular endothelial growth factor therapy.

PURPOSE: Sorafenib, a vascular endothelial growth factor (VEGF) receptor-2 and RAF kinase inhibitor, commonly causes skin toxicity. We retrospectively analyzed dermatologic toxicity in patients receiving combined antiangiogenic therapy involving sorafenib and bevacizumab. EXPERIMENTAL DESIGN: Castration-resistant prostate cancer and metastatic non-small cell lung cancer patients were accrued to phase II studies, receiving sorafenib 400 mg twice daily. A phase I study explored sorafenib 200 to 400 mg twice daily with bevacizumab 5 to 10 mg/kg every 2 weeks in patients with advanced solid tumors. The probability of development of maximum grade of dermatologic toxicity as a function of the cumulative dose of sorafenib was determined. Additional analyses compared extent of toxicity, pharmacokinetics, and patient risk factors. RESULTS: Ninety-six patients were enrolled: 54 received sorafenib and 42 received bevacizumab/sorafenib. Hand-foot skin reaction (HFSR) was observed in 50 of 96 (52%) patients. Grade 2 to 3 HFSR developed in 16 of 54 (30%) sorafenib patients and 24 of 42 (57%) bevacizumab/sorafenib patients (P=0.012) and was associated with cumulative sorafenib exposure (P=0.0008). Twenty-four of 42 phase I patients randomized to start with bevacizumab had increased risk of grade 2 to 3 HFSR than those starting with sorafenib (P=0.013) after adjusting for association between HFSR risk and hypertension (P=0.01), which was the only toxicity associated with HFSR. There was no association between HFSR and baseline history of neuropathy, prior taxane/platinum treatment, or systemic sorafenib levels. CONCLUSIONS: Sorafenib-related HFSR is associated with increasing cumulative sorafenib dose. HFSR is increased in patients treated with bevacizumab/sorafenib combination anti-VEGF therapy, and this finding is not explained by pharmacokinetic interaction between the two agents. Our results suggest that the pathophysiology of HFSR may be related to VEGF inhibition.

Voriconazole-induced phototoxicity masquerading as chronic graft-versus-host disease of the skin in allogeneic hematopoietic cell transplant recipients.

Systemic fungal infections pose a significant risk to patients following allogeneic hematopoietic cell transplantation (alloHCT). Voriconazole (Vfend, Pfizer) is an oral second-generation triazole antifungal agent that offers a broad spectrum of coverage against fungal species and is frequently utilized in the post-HCT setting. Herein, we describe 5 patients who were initially believed to be experiencing a flare of cutaneous chronic graft-versus-host disease (cGVHD), but who were actually exhibiting phototoxicity caused by voriconazole. A high index of suspicion for this adverse reaction in the post-alloHCT setting will prevent misdiagnosis and avoid inappropriate therapy for cGVHD.

Neonatal-onset multisystem inflammatory disease responsive to interleukin-1beta inhibition.

BACKGROUND: Neonatal-onset multisystem inflammatory disease is characterized by fever, urticarial rash, aseptic meningitis, deforming arthropathy, hearing loss, and mental retardation. Many patients have mutations in the cold-induced autoinflammatory syndrome 1 (CIAS1) gene, encoding cryopyrin, a protein that regulates inflammation. METHODS: We selected 18 patients with neonatal-onset multisystem inflammatory disease (12 with identifiable CIAS1 mutations) to receive anakinra, an interleukin-1-receptor antagonist (1 to 2 mg per kilogram of body weight per day subcutaneously). In 11 patients, anakinra was withdrawn at three months until a flare occurred. The primary end points included changes in scores in a daily diary of symptoms, serum levels of amyloid A and C-reactive protein, and the erythrocyte sedimentation rate from baseline to month 3 and from month 3 until a disease flare. RESULTS: All 18 patients had a rapid response to anakinra, with disappearance of rash. Diary scores improved (P<0.001) and serum amyloid A (from a median of 174 mg to 8 mg per liter), C-reactive protein (from a median of 5.29 mg to 0.34 mg per deciliter), and the erythrocyte sedimentation rate decreased at month 3 (all P<0.001), and remained low at month 6. Magnetic resonance imaging showed improvement in cochlear and leptomeningeal lesions as compared with baseline. Withdrawal of anakinra uniformly resulted in relapse within days; retreatment led to rapid improvement. There were no drug-related serious adverse events. CONCLUSIONS: Daily injections of anakinra markedly improved clinical and laboratory manifestations in patients with neonatal-onset multisystem inflammatory disease, with or without CIAS1 mutations. (ClinicalTrials.gov number, NCT00069329 [ClinicalTrials.gov].).

Description of familial keloids in five pedigrees: evidence for autosomal dominant inheritance and phenotypic heterogeneity.

BACKGROUND: Familial keloids have been reported, having either autosomal dominant or autosomal recessive inheritance. We wished to determine the inheritance pattern and phenotype of keloids among multigenerational families, as a prelude to a positional mapping strategy to identify candidate genes. METHODS: We studied three African American families, one Afro-Caribbean family and one Asian-American family. Phenotyping including assessing all patients for the presence, distribution, and appearance of keloids, together with the timing of keloid onset and provocative factors. The clinical trial was registered at clinicaltrials.gov (NCT 00005802). RESULTS: Age of keloid onset varied considerably within families, but commonly occurred by the second decade. The fraction of affected individuals was 38%, 45%, 62%, 67% and 73% among the five families respectively. Keloid severity and morphology differed within and between families. A novel finding is that certain families manifest keloids in distinct locations, with one family showing an excess of extremity keloids and two families showing an excess of axilla-groin keloids. CONCLUSION: Familial keloids appear to most commonly manifest autosomal dominant or semidominant inheritance, and there may be familial patterns of keloid distribution.

Chronic granulomatous disease as a risk factor for autoimmune disease.

Chronic granulomatous disease (CGD) is characterized by recurrent infections and granuloma formation. In addition, we have observed a number of diverse autoimmune conditions in our CGD population, suggesting that patients with CGD are at an elevated risk for development of autoimmune disorders. In this report, we describe antiphospholipid syndrome, recurrent pericardial effusion, juvenile idiopathic arthritis, IgA nephropathy, cutaneous lupus erythematosus, and autoimmune pulmonary disease in the setting of CGD. The presence and type of autoimmune disease have important treatment implications for patients with CGD.

Cutaneous sarcoidosis and primary biliary cirrhosis: A chance association or related diseases?

Sarcoidosis and primary biliary cirrhosis (PBC) are thought to be two distinct disorders of unknown origin. However, both are characterized by hepatic granuloma formation and may also manifest cutaneous granulomatous inflammation. In this report, we describe two cases of cutaneous sarcoidosis occurring in the setting of PBC and review 7 additional cases from the literature of granulomatous skin disease associated with PBC. Although the pathogenesis of both sarcoidosis and PBC remains elusive, the simultaneous occurrence of these uncommon diseases suggests a common pathway may contribute to granuloma formation in both disorders.

Itraconazole to prevent fungal infections in chronic granulomatous disease.

BACKGROUND: Chronic granulomatous disease is a rare disorder in which the phagocytes fail to produce hydrogen peroxide. The patients are predisposed to bacterial and fungal infections. Prophylactic antibiotics and interferon gamma have reduced bacterial infections, but there is also the danger of life-threatening fungal infections. We assessed the efficacy of itraconazole as prophylaxis against serious fungal infections in chronic granulomatous disease. METHODS: Thirty-nine patients at least 5 years old (6 female and 33 male; mean age, 14.9 years) were enrolled in a randomized, double-blind, placebo-controlled study. After the initially assigned treatment, each patient alternated between itraconazole and placebo annually. Patients 13 years of age or older and all patients weighing at least 50 kg received a single dose of 200 mg of itraconazole per day; those less than 13 years old or weighing less than 50 kg received a single dose of 100 mg per day. The primary end point was severe fungal infection, as determined by histologic results or culture. RESULTS: One patient (who had not been compliant with the treatment) had a serious fungal infection while receiving itraconazole, as compared with seven who had a serious fungal infection while receiving placebo (P=0.10). No patient receiving itraconazole but five patients receiving placebo had a superficial fungal infection. No serious toxic effects were noted, although one patient had a rash and another had elevated results on liver-function tests; both of these effects resolved with the discontinuation of itraconazole. CONCLUSIONS: Itraconazole prophylaxis appears to be an effective and well-tolerated treatment that reduces the frequency of fungal infections in chronic granulomatous disease, but monitoring for long-term toxic effects is warranted.

Vulvovaginal chronic graft-versus-host disease with allogeneic hematopoietic stem cell transplantation.

OBJECTIVE: To describe the diagnosis and management of female genital chronic graft-versus-host (GVH) disease, a complication of hematopoietic stem cell transplantation. METHODS: From 1999 to 2006, 33 women with vulvar symptoms or undergoing systematic evaluation for chronic GVH disease were referred 267 (median, range 29-6,117) days after transplantation for gynecologic evaluation. Pertinent histories, laboratory tests, and skin and genital area-directed examinations were performed. Vulvar disease was treated with superpotent topical glucocorticoids and topical estrogen. Sexually active, menopausal women used vaginal dilators, topical glucocorticoids and estrogen, and estrogen vaginal rings for vaginal synechiae. RESULTS: At presentation, most patients complained of vulvar pain during urination and pain that prevented sexual intercourse. Twenty-nine of 33 presenting with vulvovaginal chronic GVH disease had vulvar erythema, with additional signs including vulvar vestibulitis syndrome (n=9), vulvar erosions (n=12), vulvar scarring (n=2), and vaginal scarring (n=6); over time, eight additional patients developed vaginal scarring. Topical glucocorticoids improved vulvar symptoms, and estrogen decreased vulvar mucosal friability. Eleven of 12 patients, who wanted to resume having intercourse, responded to nonsurgical treatment for vaginal synechiae. CONCLUSION: A combination of topical superpotent glucocorticoids and estrogen was effective in the treatment of vulvovaginal chronic GVH disease. In those with vaginal scarring, use of a vaginal dilator and estrogen ring was helpful. Early identification and treatment of vulvovaginal chronic GVH disease ameliorates vulvar pain by healing eroded vulvar mucosa and may prevent the need for surgery for hematocolpos. LEVEL OF EVIDENCE: III.

Development and reliability testing of a standardized questionnaire to assess psoriasis phenotype.

BACKGROUND: Psoriasis genetics researchers have utilized separate and widely differing survey instruments to capture clinical data to be utilized in genotype-phenotype studies, which make comparison and collaboration studies among these researchers difficult. OBJECTIVE: The purpose of this study was to develop and validate a clinical survey instrument to facilitate future collaborative genotype-phenotype studies among psoriasis genetics researchers. METHODS: The Delphi method was employed to obtain international consensus on components of the novel survey instrument. The survey was pretested for acceptability purposes, and then formally tested for reliability using 3 independent raters interviewing 48 subjects with psoriasis. RESULTS: Data showed high or moderately high agreement for questions relating to place of birth (85% to 100% in agreement), family origin (kappa = 0.48 -1.0), psoriasis history (kappa = 0.66-1.0), patient medical history (kappa = 0.76-1.0), distribution of lesions (kappa = 0.73-1.0), precipitating factors (kappa = 0.79-1.0), joint involvement (kappa = 0.74-.91), and treatment history, including use of oral retinoids, methotrexate, and etanercept (kappa = 0.73-1.0). Other parameters had lower degrees of agreement. LIMITATIONS: The time involved and the need for the rater to be a clinician with knowledge of psoriasis may preclude widespread use of this survey instrument. CONCLUSION: We developed a novel, reliable survey instrument that can be used to gather clinical information in a standardized manner from psoriasis patients participating in clinical and genetics research studies.
