Hepatokine Profile in Adolescents with Polycystic Ovary Syndrome: A Case-Control Study.

The current guidelines suggest routine screening for non-alcoholic fatty liver disease (NAFLD) in patients with polycystic ovary syndrome (PCOS). Hepatokines seem to be promising surrogate endpoints for the diagnosis and severity of NAFLD. PCOS has its onset in adolescence and its metabolic sequalae begin during the same period. There are scarce data on the hepatokine profile of adolescent PCOS patients. This case-control study examined the serum profile of the hepatokines sex hormone-binding globulin (SHBG), selenoprotein P, fibroblast growth factor 21 (FGF21), and fetuin A in a sample of adolescent PCOS patients, and their association to metabolic and hormonal parameters. The selenoprotein P and SHBG serum concentrations were significantly decreased in PCOS patients vs. the controls (median (IQR), 2.47 (0.40) vs. 2.66 (0.36) µg/mL, p = 0.025; mean ± SD, 41.71 ± 19.41 vs. 54.94 ± 22.12 nmol/L, p = 0.011, respectively), whereas selenoprotein P was significantly and positively associated with testosterone (r = 0.325, p = 0.007) and the free androgen index (r = 0.361, p = 0.002). The SHBG demonstrated multiple significant negative correlations with adverse metabolic parameters. Among the PCOS patients, the FGF21 concentrations were significantly higher in those with NAFLD, whereas a 1 pg/mL increase in the FGF21 concentration increased the odds of NAFLD diagnosis by liver ultrasound by 1%, suggesting FGF21 as a potential biomarker for hepatic disease in females with PCOS in adolescence. Fetuin A was the least differentiated hepatokine between the PCOS patients and controls with the least associations with metabolic and hormonal parameters.

The Burden of Non-Alcoholic Fatty Liver Disease in Adolescents with Polycystic Ovary Syndrome: A Case-Control Study.

The aim of this case-control study was to assess the burden of non-alcoholic fatty liver disease (NAFLD) in adolescents with polycystic ovary syndrome (PCOS) and its associations with insulin resistance, hyperandrogenism, and other metabolic characteristics of the syndrome. A total of 87 Caucasian adolescent girls (47 with PCOS and 40 controls), aged 12.3-20.4 years, underwent blood sampling for glucose metabolism, hormonal and lipid profile, gynecological and liver ultrasound, and liver elastography. Indices of insulin resistance, liver steatosis, and liver fibrosis were calculated. NAFLD diagnosed by ultrasound was more prevalent in adolescents with PCOS than controls (22.7% vs. 6.1%, p = 0.046), and was also verified by liver steatosis indices. The latter was not apparent for hepatic fibrosis, as assessed by Fibroscan® and calculated indices. The homeostatic model assessment for insulin resistance (HOMA-IR) was found to predict NAFLD diagnosis by the liver fat score (LFS) index (ß = 0.709, p = 0.002). Adolescents with PCOS and high free androgen index (FAI) presented worse NAFLD than those adolescents with PCOS and lower FAI. In addition, adolescents with PCOS and concurrent NAFLD had worse insulin sensitivity indices (HOMA-IR, QUICKI, and glucose to insulin ratio) than adolescents with PCOS alone. Adolescent insulin resistance could be considered a confounder of the association between PCOS and NAFLD.

Bone disease in patients with cirrhosis of different etiology and severity; are Klotho protein and osteoprotegerin potential biomarkers?

BACKGROUND AND AIMS: Cirrhosis is associated with increased risk for osteoporosis and osteopenia. This study aims to further investigate this relationship by examining if etiology and severity of cirrhosis are independent predictors of bone mineral density (BMD) loss. Furthermore we examined the serum levels of osteoprotegerin (OPG) and Klotho proteins that have been involved in bone metabolism. METHODS: Seventy-four patients with cirrhosis of different etiology and 25 matched healthy controls were included in this study. Bone mineral densitometry at both lumbar spine and femoral neck was measured. Serum total OPG, Klotho protein and vitamin D levels were also determined. Comparisons were performed according to etiology and severity of cirrhosis. RESULTS: Decreased bone density was observed in cirrhotic patients compared to healthy controls with T = -1.46 and T = -1.37 in lumbar spine and femoral bone respectively compared to T = -0.396 and T = -0.672 in the control group. In the cirrhotic group, osteopenia was observed in 46% in lumbar spine and 51% in femoral bone whereas osteoporosis was observed in 20% in lumbar spine and 9% in femoral bone. Decreased bone density was confirmed, regardless of cirrhosis etiology or stage of liver function. Patients were found to have higher levels of OPG than the control group (136 pg/ml vs. 67 pg/ml, p < 0.001), but lower levels of Klotho protein (1051 pg/ml vs. 1842 pg/ml, p < 0.001) regardless etiology and severity of cirrhosis. High OPG levels were found to be associated with low femoral bone density. CONCLUSIONS: BMD is lower in cirrhotic patients regardless etiology and severity of liver disease with osteopenia and osteoporosis be present in 50% and 20%, respectively. Higher levels of OPG and lower levels of Klotho protein were observed in cirrhotic patients regardless etiology and severity in comparison to matched healthy group.

Eosinophilic Myocarditis in a Patient With Strongyloides stercoralis Infection.

A 40-year-old woman with a pulmonary embolism, central nervous system infarcts, and eosinophilia was referred for evaluation. Findings on echocardiography and cardiac magnetic resonance were consistent with eosinophilic myocarditis with left ventricular involvement. Further examination led to the diagnosis of Strongyloides stercoralis infection, and treatment with ivermectin and rivaroxaban resulted in clinical, laboratory, and cardiac imaging improvement. (Level of Difficulty: Intermediate.).

Fatal Streptococcus pseudoporcinus disseminated infection in decompensated liver cirrhosis: a case report.

BACKGROUND: Streptococcus pseudoporcinus (S. pseudoporcinus) was first identified in 2006. It cross-reacts with Lancefield group B antigen agglutination reagents and has been misidentified as S. agalactiae. Sites of S. pseudoporcinus isolation include the female genitourinary tract, urine, wounds, and dairy products. The prevalence of vaginal colonization is reportedly between 1 and 5.4%. Two uneventful cases of soft tissue infection caused by S. pseudoporcinus were reported in the past. However, since late 2019, six cases of invasive S. pseudoporcinus infections have emerged in the literature, one of which was fatal. CASE PRESENTATION: We describe a fatal case of a Caucasian male with spontaneous bacterial peritonitis associated with bacteremia due to a multidrug-resistant S. pseudoporcinus strain in a patient with decompensated liver cirrhosis. Despite the patient's good general condition and stable blood test results when he had visited the outpatient clinic for large-volume paracentesis a few days before admission, this time he presented to the emergency department with a rapidly worsening clinical condition and with laboratory features consistent with multiple-organ dysfunction syndrome, and succumbed within a short period. CONCLUSIONS: Contrary to what was thought until recently, multidrug-resistant S. pseudoporcinus may cause invasive, disseminated, fatal disease in humans. According to current limited data, vancomycin, linezolid, daptomycin, levofloxacin, clindamycin, and tetracycline seem to be the most effective antimicrobial agents against multidrug-resistant strains, and should be the empirical choice in cases of disseminated S. pseudoporcinus infection until laboratory antimicrobial susceptibility results are available. Improvements and new approaches for bacterial identification in routine clinical microbiology laboratories may reveal the real spectrum of S. pseudoporcinus infections in humans, which is currently believed to be underestimated. SS. pseudoporcinus could emerge as a serious medical problem in the near future, similar to other ß-hemolytic streptococci.

Diabetes mellitus in the era of climate change.

Worldwide, diabetes mellitus (DM) represents a major public-health problem due to its increasing prevalence in tandem with the rising trend of obesity. However, climate change, with its associated negative health effects, also constitutes a worrisome problem. Patients with DM are experiencing more visits to emergency departments, hospitalizations, morbidity and mortality during heat waves at ever-increasing numbers. Such patients are particularly vulnerable to heat waves due to impaired thermoregulatory mechanisms in conjunction with impaired autonomous nervous system responses at high temperatures, electrolyte imbalances and rapid deterioration of kidney function, particularly among those aged > 80 years and with preexisting chronic kidney disease (CKD). Moreover, exposure to cold temperatures is associated with increased rates of acute myocardial infarction as well as poor glycaemic control, although results are conflicting regarding cold-related mortality among patients with DM. In addition to extremes of temperature, air pollution as a consequence of the climate crisis may also be implicated in the increased prevalence and incidence of DM, particularly gestational DM (GDM), and lead to deleterious effects in patients with DM. Thus, more large-scale studies are now required to elucidate the association between specific air pollutants and risk of DM. This review presents the currently available evidence for the detrimental effects of climate change, particularly those related to weather variables, on patients with DM (both type 1 and type 2) and GDM. Specifically, the effects of heat waves and extreme cold, and pharmaceutical and therapeutic issues and their implications, as well as the impact of air pollution on the risk for DM are synthesized and discussed here.

Clinical characteristics and outcomes of measles outbreak in adults: A multicenter retrospective observational study of 93 hospitalized adults in Greece.

OBJECTIVES: Measles outbreaks are increasingly reported among countries that were close-to-eliminate measles infection. There are few reports of clinical characteristics of measles in adults in the contemporary literature. In this study we aim to describe the clinical characteristics and complications of measles infection in hospitalized adults during the recent epidemic in Greece. METHODS: A multicentre observational retrospective study was conducted in three tertiary hospitals in Greece. All adult hospitalized patients (≥18 years old) with serologically confirmed and/or clinical features compatible with measles were included. Pediatric patients and patients with missing data were excluded. RESULTS: In total, 93 patients, 40 males (43 %) and 53 females (57 %), mostly young patients were included. Most of them (87 %) had no past medical history. Among women, 4 were pregnant. 56 (60.2 %) and 25 (26.9 %) patients reported either unknown or incomplete vaccination for measles. Ribavirin was administered in 8 (8.6 %) patients. Pneumonitis and hepatic involvement were the most common complications, occurring in 43 (46.2 %) and 75 (80.6 %) patients respectively. Pneumonitis was significantly associated with male sex, older age, lower lymphocyte counts and higher C-reactive protein (CRP) on admission. One pregnant woman suffered spontaneous fetal miscarriage and one patient died due to acute respiratory distress syndrome (ARDS) and high-risk pulmonary embolism. CONCLUSION: Considerable proportions of incompletely vaccinated or unvaccinated adults have led to the re-emergence of measles in countries with reported close-to-elimination rates. Pneumonitis is a major complication among adults with measles. More studies are imperative in order to explore the role of immune paresis in measles.

Interleukin-17A and B-cell activating factor in chronic hepatitis C patients with or without asymptomatic mixed cryoglobulinemia: effects of antiviral treatment and correlations with vitamin D.

BACKGROUND: Several studies have provided conflicting results regarding the immune responses in chronic hepatitis C (CHC) patients with mixed cryoglobulinemia (MC). The importance of B-cell activating factor (BAFF) in MC has been described, but the role of interleukin (IL)-17A is less clear. METHODS: Serum concentrations of IL-17A, BAFF and 25-OH vitamin D were measured in CHC patients at baseline, end of treatment, and 6 months post-treatment with pegylated interferon-α and ribavirin, versus 12 healthy controls. RESULTS: Thirty-four patients (20 male, mean age 40.7±9.2 years, 12 of genotype 1 or 4, 22 of genotype 2 or 3) were included, of whom 64.7% achieved a sustained virological response (SVR). MC was detected in 52.9% of the patients. Higher levels of both cytokines were found in patients with MC compared to those without. Patients who achieved SVR had higher pretreatment IL-17A and lower BAFF levels compared to those without SVR. IL-17A was downregulated during and following treatment in responders, whereas upregulation was observed in non-responders. CHC patients demonstrated low vitamin D levels compared to HC. Moreover, the changes in IL-17A over the treatment period were significantly associated with vitamin D changes (ß=-0.04, SE=0.02, P=0.046). No difference in IL-17A, BAFF and vitamin D values was seen between patients with cirrhosis (n=14) and those without. CONCLUSIONS: CHC patients with asymptomatic MC have increased levels of IL-17A and BAFF. IL-17A levels decline significantly while BAFF increases during treatment in responders. An interplay between IL-17A and vitamin D concentrations was revealed during the antiviral treatment.

Cytomegalovirus infection in a splenectomized with ß-thalassemia major: immunocompetent or immunosuppressed?

We should possibly revise our knowledge about risk assessment of splenectomized individuals with ß-thalassemia major. Besides their known risk of certain bacterial infection, they might be also in a risk of life-threatening primary cytomegalovirus (CMV) infection and end-, multi-organ disease, in the context of their immunosuppression status. Prompt and appropriate treatment initiation can be life saving.

Clinical presentation, diagnosis, and survival in cholangiocarcinoma: A prospective study.

BACKGROUND AND STUDY AIMS: The diagnosis of cholangiocarcinoma (CCA) is difficult. The present study aimed to assess the clinical features, diagnosis, and survival in CCA. PATIENTS AND METHODS: This is a prospective study on 46 patients with CCA who underwent endoscopic retrograde cholangiopancreatography (ERCP) or surgical resection and 20 controls with a clinical and ERCP suspicion for CCA in whom surgical biopsy and/or 4-year follow-up showed a benign biliary stricture. RESULTS: The median age at presentation was 71years (range 44-88). Thirty-four patients (73.9%) presented with painless jaundice. Median CA 19-9 value was 188IU/L (range 1-49,138), with a level of <100IU/L in 13 patients (28%). Total bilirubin was 11.9 (0.6-36.3)mg/dL. The tumour was intrahepatic in 3 (6.5%), hilar (Klatskin) in 25 (54.3%), and located in the lower third of the bile duct in 18 (39.1%) patients. The diagnosis was confirmed by positive cytology in 10 (21.7%), biopsy in 20 (43.5%), cholangioscopy in five (10.9%), and imaging and clinical grounds in 11 (23.9%) patients. Cytology was feasible in 36 patients; it was positive in 10 and "highly indicative" in two patients (33.3% sensitivity). Twenty-two patients (47.8%) were treated by surgical resection, and the rest were offered palliative biliary drainage. Mean estimated survival for the entire group of CCA patients was 21.5±3.3months. Survival was slightly longer in patients who underwent surgical resection than those who had palliative treatment; the estimated mean survival rates were 26.2±4.2 vs. 17.1±3.3months, respectively, but the difference was not statistically significant (p=0.115). CONCLUSION: The diagnosis of CCA is difficult and often delayed. The outcome is generally poor.

Extensively drug-resistant bacteria are an independent predictive factor of mortality in 130 patients with spontaneous bacterial peritonitis or spontaneous bacteremia.

AIM: To evaluate the epidemiology and outcomes of culture-positive spontaneous bacterial peritonitis (SBP) and spontaneous bacteremia (SB) in decompensated cirrhosis. METHODS: We prospectively collected clinical, laboratory characteristics, type of administered antibiotic, susceptibility and resistance of bacteria to antibiotics in one hundred thirty cases (68.5% males) with positive ascitic fluid and/or blood cultures during the period from January 1, 2012 to May 30, 2014. All patients with SBP had polymorphonuclear cell count in ascitic fluid > 250/mm(3). In patients with SB a thorough study did not reveal any other cause of bacteremia. The patients were followed-up for a 30-d period following diagnosis of the infection. The final outcome of the patients was recorded in the end of follow-up and comparison among 3 groups of patients according to the pattern of drug resistance was performed. RESULTS: Gram-positive-cocci (GPC) were found in half of the cases. The most prevalent organisms in a descending order were Escherichia coli (33), Enterococcus spp (30), Streptococcus spp (25), Klebsiella pneumonia (16), S. aureus (8), Pseudomanas aeruginosa (5), other Gram-negative-bacteria (GNB) (11) and anaerobes (2). Overall, 20.8% of isolates were multidrug-resistant (MDR) and 10% extensively drug-resistant (XDR). Health-care-associated (HCA) and/or nosocomial infections were present in 100% of MDR/XDR and in 65.5% of non-DR cases. Meropenem was the empirically prescribed antibiotic in HCA/nosocomial infections showing a drug-resistance rate of 30.7% while third generation cephalosporins of 43.8%. Meropenem was ineffective on both XDR bacteria and Enterococcus faecium (E. faecium). All but one XDR were susceptible to colistin while all GPC (including E. faecium) and the 86% of GNB to tigecycline. Overall 30-d mortality was 37.7% (69.2% for XDR and 34.2% for the rest of the patients) (log rank, P = 0.015). In multivariate analysis, factors adversely affecting outcome included XDR infection (HR = 2.263, 95%CI: 1.005-5.095, P = 0.049), creatinine (HR = 1.125, 95%CI: 1.024-1.236, P = 0.015) and INR (HR =1.553, 95%CI: 1.106-2.180, P = 0.011). CONCLUSION: XDR bacteria are an independent life-threatening factor in SBP/SB. Strategies aiming at restricting antibiotic overuse and rapid identification of the responsible bacteria could help improve survival.

Soluble CD146, a novel endothelial marker, is related to the severity of liver disease.

OBJECTIVES: Angiogenesis and inflammation have been involved in the progression of fibrosis in patients with chronic liver disease (CLD). Soluble CD146 (sCD146), a biomarker that was recently characterized as a novel component of the endothelial junction is implicated in endothelial proliferation. Our study evaluates the performance of sCD146 in assessing liver fibrosis and cirrhosis, and determines if its levels are related to the severity of liver disease in patients with cirrhosis. MATERIAL AND METHODS: sCD146 levels were determined by a commercially available immunoenzymatic technique in 62 consecutive patients with cirrhosis, 43 patients with CLD and 27 healthy controls. RESULTS: Patients with cirrhosis compared to non-cirrhotics with CLD had a higher median sCD146 concentration (639 vs. 317 ng/ml). In receiver operating characteristic (ROC) curve analysis, the cut-off of 412 ng/ml showed a sensitivity of 78% and a specificity of 75% for diagnosis of cirrhosis, offering good diagnostic accuracy (area under the ROC curve [AUROC: 0.838]). Patients with compensated compared to those with decompensated cirrhosis had a lower median sCD146 concentration (399 vs. 848 ng/ml, respectively). A cut-off of 534 ng/ml offered a sensitivity of 83% and a specificity of 78% for differentiating compensated from decompensated cirrhosis (AUROC: 0.866). Furthermore, in cirrhotics, sCD146 correlated positively with AST, bilirubin levels and most importantly with international normalized ratio and model for end-stage liver disease (r = 0.648, p < 0.001 and r = 0.567, p < 0.001, respectively). CONCLUSION: sCD146 can be used as a surrogate, inexpensive biomarker for the diagnosis of cirrhosis. It is also well correlated with severity of liver disease in cirrhotic patients. Further studies are needed to define its role in clinical practice.

Presence of spur cells as a highly predictive factor of mortality in patients with cirrhosis.

BACKGROUND AND AIM: The presence of spur-cell anemia (SCA) is due to lipid disturbances of the erythrocyte membrane and may develop in patients with advanced liver cirrhosis. The accurate predicting value of SC for survival has not been clarified. The aim of this study was to evaluate SCA as a prognostic indicator in patients with cirrhosis. METHODS: We prospectively evaluated clinical, laboratory parameters, and survival in patients with cirrhosis, with or without SCA, during the period 2008-2011. Patients who had at admission renal failure, other causes of hemolytic anemia, hepatocellular carcinoma, sepsis, and/or active bleeding, were excluded. One hundred sixteen patients with cirrhosis were included. The presence of SCA (SC rate higher or equal to 5% [≥ 5%]) was diagnosed in 36 (31%) patients. RESULTS: Patients with SCA compared to those without had more advanced liver disease (higher Model for End-Stage Liver Disease [MELD], P < 0.001), higher total bilirubin (P < 0.001), and International Normalized Ratio (P < 0.001). Patients with SCA had worse survival (log rank P < 0.001). Survival of patients with SCA at the first, second, and third month of follow-up was 77%, 45%, and 33%, respectively. In multivariate Cox's regression analysis, the presence of SCA was an independent predictor of mortality (hazard ratio = 3.17 [95% CI 1.55-6.48]). CONCLUSIONS: The presence of spur-cell anemia is not uncommon in cirrhosis and seems to be strongly associated with mortality. SCA can be used in combination with MELD as an additional predictor of early mortality.

An extended fluorescence in situ hybridization approach for the cytogenetic study of cholangiocarcinoma on endoscopic retrograde cholangiopancreatography brushing cytology preparations.

The cytological diagnosis of cholangiocarcinoma has been significantly aided by applying a 4-probe fluorescence in situ hybridization system on endoscopic retrograde cholangiopancreatography brushing smears, aiming mainly at the detection of hyperdiploidy. However, this approach adds little to our understanding of the genetic background of the disease. With the prospect of obtaining additional data on chromosomal aberrations, we have extended the fluorescence in situ hybridization study, with the application of 4 independent 2-probe systems in 35 patients with documented cholangiocarcinoma. Fluorescence in situ hybridization assays were performed on endoscopic retrograde cholangiopancreatography brushing smears, with probes for the 7q31, 11q13 (CCND1), 17p53 (TP53), and 9p21 (INK4 locus) bands, together with the respective centromeric probe. Hyperdiploidy, involving at least 2 of the 4 chromosomes targeted, was found in 31 patients. 17p13 deletion was detected in 3, and 9p21 deletion, in 5 of the hyperdiploid cases, with the 2 aberrations concurrent in 1. CCND1 amplification was found in 1 case as the sole abnormality and in another together with hyperdiploidy, but in apparently unrelated clones. This work indicates that interphase fluorescence in situ hybridization is a practical and useful tool for the cytogenetic study of cholangiocarcinoma on endoscopic retrograde cholangiopancreatography brushing smears, which is often the only available tissue specimen of the tumor. Apart from hyperdiploidy, it provides additional data on the genetic profile of cholangiocarcinoma, especially regarding structural chromosomal aberrations and clonal diversity. This line of investigation may prove useful in the delineation of oncogenesis and the interpretation of the diverse clinical features of the disease.

Sarcoid-like granulomatosis in patients treated with anti-TNFα factors. A case report and review of the literature.

This report describes a 56-year-old woman who developed granulomatous lesions consistent with sarcoidosis during adalimumab therapy for rheumatoid arthritis. Cervical and axillary lymphadenopathy developed approximately 21 months after adalimumab administration. Non-caseating epithelioid cell granulomas consistent with sarcoidosis were detected both in an axillary lymph node specimen and in the bone marrow. Diseases showing similar histologic changes, especially tuberculosis, were excluded, and a diagnosis of sarcoidosis was made. Adalimumab was discontinued, and recovery was observed. The current case is, to our knowledge, the first to describe adalimumab-induced non-caseating granulomas in lymph nodes and bone marrow without pulmonary involvement in a patient treated for rheumatoid arthritis.

Nitric oxide, ammonia, and CRP levels in cirrhotic patients with hepatic encephalopathy: is there a connection?

GOALS: Comparison of nitric oxide (NO) levels in cirrhotic patients with and without hepatic encephalopathy (HE), evaluation of possible correlation between HE and other clinical or laboratory characteristics, and estimation of utilization of NO levels in clinical practice. BACKGROUND: HE is a neuropsychiatric complication of cirrhosis. The exact pathogenetic mechanisms underlying the presence of HE are not known. However, dysfunction of the NO pathway and ammonia detoxification are thought to play a major role. STUDY: Sixty-seven cirrhotic patients, 36 (53.7%) without HE, and 31 (46.3%) with HE were included in the study. Eighteen healthy individuals were used as control group. Clinical and laboratory data, including ammonia and stable end products of NO using Griess reaction, were collected. RESULTS: NOx levels were statistically significantly higher in cirrhotic patients (225.5 µmol/L) than in control group [(67.94 µmol/L) (P=0.000)]. NOx levels were, also, statistically significantly higher in patients with HE compared with patients without HE (324.67 µmol/L vs. 141.96 µmol/L, P=0.000). Significant correlation between the presence of HE and NOx, ammonia, C-reactive protein, albumin, Model for End-Stage Liver Disease score, and Child-Pugh classification revealed. NOx levels also correlated with severity of HE. NOx and ammonia are independent factors predicting HE according to regression analysis. Diagnostic accuracy for the diagnosis of HE using a combination of NOx and ammonia was superior compared with standalone NOx or ammonia utilization. CONCLUSIONS: NOx levels are correlated with the presence and severity of HE. NOx levels determination, in addition to ammonia levels, could contribute in diagnosis of HE.

The burden of incidental findings in clinical practice in a tertiary care center.

BACKGROUND: To evaluate the prevalence and clinical burden of serendipitously discovered abnormalities in hospitalized patients, unrelated to their presenting symptoms and physical signs. METHODS: A total of 478 patients consecutively admitted in the Department of Medicine were enrolled in the study. In the end of first diagnostic work-up, the previously undetected imaging or endoscopic asymptomatic abnormalities termed as incidental findings (IFs) were recorded and some of them were further investigated. RESULTS: One hundred thirty eight (28.8%) patients had IFs. The most common IFs were located in the kidney and genitourinary system followed by liver and gallbladder. The most common method of detection of IFs was ultrasonography (US) of the abdomen. The patients with IFs compared with those without, were older (P=0.007), had no previous hospitalizations (P<0.001) and stayed longer in the hospital (P<0.001). The 25 (18.1%) patients with IFs were not evaluated further. One hundred seventy seven IFs discovered in 113 patients were further evaluated by medical specialists and additional tests were performed if warranted. In the end of the diagnostic work-up, in a total of 113 patients with IFs, 78.7% had insignificant and 21.2% potentially significant IFs. The latter group had higher rate of IFs compared with the former group, usually more than 3 (P=0.017). CONCLUSIONS: IFs were prevalent in a hospital population. Hospitalized patients with IFs were more than 60 years old and had no previous hospitalization. A large number of IFs were potentially significant deserving further clinical management.

Autoimmune blistering disease in a patient with Graves disease and vitiligo.

Autoimmune thyroid diseases have been correlated with a variety of autoimmune diseases also affecting the skin. A 56-year-old patient with a history of vitiligo is presented who was admitted for hyperthyroidism (Graves disease) and a blistering eruption. Clinical and histological appearance of the skin disorder, rapid response to corticosteroids, recurrence and remission of the lesions with discontinuation and reintroduction of corticosteroids, respectively, were all suggestive of an autoimmune blistering disease accompanying autoimmune hyperthyroidism and vitiligo.

Simultaneous development of diabetic ketoacidosis and Hashitoxicosis in a patient treated with pegylated interferon-alpha for chronic hepatitis C.

Classical interferon-alpha has been shown to be correlated with the development of a variety of autoimmune disorders. A 38 year-old female patient developed simultaneously diabetic ketoacidosis and hyperthyroidism 5 mo following initiation of treatment with pegylated interferon-alpha and ribavirin for chronic hepatitis C. High titers of glutamic acid decarboxylase, antinuclear and thyroid (thyroid peroxidase and thyroglobulin) antibodies were detected. Antiviral treatment was withdrawn and the patient was treated with insulin for insulin-dependent diabetes mellitus and propranolol for hyperthyroidism. Twelve months after cessation of pegylated interferon-alpha therapy the patient was euthyroid without any medication but remained insulin-dependent.
