RESUMO
OBJECTIVES: PEPDar compared the tolerability and safety of ritonavir-boosted darunavir (DRV/r)-based post-exposure prophylaxis (PEP) with the tolerability and safety of standard of care (SOC). The primary endpoint was the early discontinuation rate among the per-protocol population. METHODS: PEPDar was an open-label, randomized, multicentre, prospective, noninferiority safety study. Subjects were stratified by type of event (occupational vs. nonoccupational, i.e. sexual) and were randomized to receive DRV/r plus two nucleoside reverse transcriptase inhibitors (NRTIs) or SOC PEP. Twenty-two private or university HIV clinics in Germany participated. Subjects were ≥ 18 years old and had documented or potential HIV exposure and indication for HIV PEP. They initiated PEP not later than 72 h after the event and were HIV negative. RESULTS: A total of 324 subjects were screened, the per-protocol population was 305, and 273 subjects completed the study. One hundred and fifty-five subjects received DRV/r-based PEP and 150 subjects received ritonavir-boosted lopinavir (LPV/r)-based PEP for 28-30 days; 298 subjects also received tenofovir/emtricitabine. The early discontinuation rate in the DRV/r arm was 6.5% compared with 10.0% in the SOC arm (P = 0.243). Adverse drug reactions (ADRs) were reported in 68% of DRV/r subjects and 75% of SOC subjects (P = 0.169). Fewer DRV/r subjects (16.1%) had at least one grade 2 or 3 ADR compared with SOC subjects (29.3%) (P = 0.006). All grades of diarrhoea, nausea, and sleep disorders were significantly less frequent with DRV/r, while headache was significantly more frequent. No HIV seroconversion was reported during follow-up. CONCLUSIONS: Noninferiority of DRV/r to SOC was demonstrated. DRV/r should be included as a standard component of recommended regimens in PEP guidelines.

Nonerosive reflux disease (NERD) is commonly diagnosed in patients with symptoms of reflux. The aim of the present study was to determine whether high-definition endoscopy (HD) plus equipped with the iScan function or chromoendoscopy with Lugol's solution might permit the differentiation of NERD patients from those without reflux symptoms, proven by targeted biopsies of endoscopic lesions. A total of 100 patients without regular intake of proton pump inhibitors and with a normal conventional upper endoscopy were prospectively divided into NERD patients and controls. A second upper endoscopy was performed using HD+ with additional iScan function and then Lugol's solution was applied. Biopsy specimens were taken from the gastroesophageal junction in all patients. A total of 65 patients with reflux symptoms and 27 controls were included. HD(+) endoscopy with iScan revealed subtle mucosal breaks in 52 patients; the subsequent biopsies confirmed esophagitis in all cases. After Lugol's solution, 58 patients showed mucosal breaks. Sensitivity for the iScan procedure was 82.5%, whereas that for Lugol's solution was 92.06%. Excellent positive predictive values of 100% and 98.3%, respectively, were noted. The present study suggests that the majority of patients with NERD and typical symptoms of reflux disease can be identified by iScan or Lugol's chromoendoscopy as minimal erosive reï¬ux disease (ERD) patients.

PURPOSE: To assess rate of late presentation with HIV in Southwestern Germany and to identify patient characteristics correlated with CD4 nadir. METHODS: Patients with primary diagnosis who presented to one of ten participating clinics rated on knowledge and behavior towards HIV testing on a self-developed questionnaire, whereas clinical data was assessed by the physician. RESULTS: 161 patients were included. Risk factors were homosexual (59.5 %) or heterosexual contacts (26.8 %), drug use (2.0 %), migration (3.9 %), or others (7.8 %). 63.5 % had a CD4 T cell count < 350/µl. 52.5, 17.4, and 31.1 % were diagnosed in CDC stadium A, B or C, respectively. 209 disease episodes were reported, from whom 83.7 % had led to the diagnosis of HIV. 75.2 and 68.3 % said to have been well-informed about ways of transmission and testing offerings, respectively, and 20.4 % admitted to have psychologically repressed the possibility of being infected. 48 patients rated their personal behavioral risk as "high" or "very high". Of these, however, only ten had performed at test in the precedent year. Performing a regression analysis, younger age and previous testing were correlated with a higher CD4 T cell nadir (p = 0.005, and 0.018, resp.). CONCLUSION: The rate of late presentation in this region was even higher compared to national or European surveys. Most infected patients perceived to have had only a low risk. Several disease episodes did not lead to the initiation of HIV testing by the physician.

BACKGROUND: Liver cirrhosis develops as a terminal complication of chronic liver disease. The clinical course is determined by the underlying etiology and the accompanying risk factors, which are influenced by the geographic and cultural background. METHODS: A total of 236 patients (159 men, 77 women, median age 57 [22-81] years) were included for retrospective analysis between July 2012 and February 2014 using standardized questionnaires during an outpatient visit at a hepatology clinic. RESULTS: The most common etiologies of liver cirrhosis were related to alcohol consumption (52â%), chronic hepatitis C (28â%) or hepatitis B (14â%) infection and NASH (nonalcoholic steatohepatitis, 6â%). At the time of presentation 55â% patients had compensated cirrhosis corresponding to Child-Turcotte-Pugh (CTP) stage A, while 45â% were in a decompensated stage (30â% CTP B and 15â% CTP C). Subgroups were analyzed for the incidence of complications and the emergence of infections. Most frequently esophageal varices (60â%) and ascites (49â%) were observed, followed by pleural effusion (14â%), hepatic encephalopathy (25â%) or hepatorenal syndrome (18â%). 16â% of patients exhibited infection based on clinical criteria. An infective agent was isolated in 38â% of all cases with infection and of those 50â% were gram positive bacteria. In multivariate analysis only the presence of ascites was an independent risk factor for infection. CONCLUSION: Despite improved medical therapies for viral hepatitis, these were the most frequent causes of liver cirrhosis, closely followed by alcoholic cirrhosis. The observed complications included bacterial infection and complication related to portal hypertension.

Indeterminate strictures of the bile ducts are common diagnostic dilemmas in gastroenterology, and differential diagnosis includes inflammatory and neoplastic diseases. Alveolar echinococcosis (AE) is rarely considered as a differential diagnosis, although it is endemic in the Northern hemisphere. In this case report on a 50-year-old male patient, the lack of cystic lesions or calcifications on CT, and suggestive ERCP findings made a hilar cholangiocellular carcinoma the most probable differential diagnosis, and only explorative laparotomy provided the definite diagnosis of AE. AE should therefore be included in the differential diagnosis of indeterminate biliary strictures even in the absence of typical stigmata in imaging studies.

Disclosure is a prerequisite to receive disease-specific social support. However, in the case of a stigmatised disease, it can also lead to discrimination. We aimed to assess disclosure rates of HIV patients and the reactions they encountered in comparison to patients with chronic viral hepatitis or diabetes mellitus and patients' general perception of disease-specific discrimination. We constructed a self-report questionnaire, anonymously assessing the size of the social environment, the persons who had been informed, and the experienced reactions as perceived by the disclosing patients, to be rated on 1-4 point Likert scales. In addition, patients were asked whether they perceive general discrimination in Germany. One hundred and seventy-one patients were asked to participate. Five rejected, thus questionnaires from 83 patients with HIV, 42 patients with chronic viral hepatitis B (n = 9) or C (n = 33), and 41 patients with insulin-dependent diabetes mellitus (type I n = 14, type II n = 27) were analysed. Whereas the size of the social environment did not differ, HIV-infected patients were least likely to disclose their disease (60.7%, SD ± 31.9) to their social environment as compared to patients with chronic viral hepatitis (84.2 ± 23.3%, p<0.0001), or diabetes mellitus (94.4 ± 10.3%, p<0.0001), respectively. Within the HIV patient group, the mean disclosure rate was highest to partners (90.9%), followed by the public environment (65.2%), friends (59.4%) and family members (43.8%). HIV patients experienced supportive reactions after 79.3 ± 26.4% of disclosures, which was the case in 91.4 ± 19.6% and 75.7 ± 36.1% of patients with hepatitis or diabetes mellitus, respectively. 69.5% of HIV patients stated to perceive general discrimination in Germany. We conclude that HIV patients had experienced supportive reactions after the majority of disclosures, but the low rate points out that their information strategy had been very selective. Societal discrimination of HIV patients is still an issue and needs to be further addressed.

A 35-year-old Kenian lady with advanced immunodeficiency due to HIV infection started on an antiretroviral therapy. Five months later, a severe colitis was diagnosed, however, no causal pathogen could be found. In order to avoid imminent perforation, a hemicolectomy became necessary, and immediately the symptoms and inflammation markers normalized rapidly. M. tuberculosis could be proven in culture in a draining abdominal lymph node. We assume that the severe inflammation was caused by an immune restoration inflammatory syndrome (IRIS). Essentials in diagnosis, pathogenesis and therapy of IRIS are discussed.

Esophageal involvement in the context of opportunistic infections in human immunodeficiency virus (HIV) positive patients is a frequent phenomenon. However, worldwide esophageal achalasia has been described only twice in HIV-infected patients.We report the case of a 44-year-old Caucasian patient with HIV and Hepatitis C virus (HIV/HCV) coinfection who, within 2.5 years, displayed a progressive symptomatology with dysphagia, retrosternal pain, regurgitation as well as a considerable loss of weight before achalasia was finally diagnosed. Treatment was performed primarily surgically by means of laparoscopic Heller myotomy with an anterior 180° semifundoplication according to Dor.Histopathology of the specimens taken from the lower esophageal sphincter high-pressure zone proved alterations with abundant connective tissue and only scarce parts of the smooth muscular system without inflammatory infiltrations. In addition, the ganglia cells of the myenteric plexus as well as the interstitial cells of Cajal were significantly reduced. Interestingly, specific gene sequences of the hepatitis C virus could be detected in the esophageal tissue specimen. In contrast, analysis of specific HIV-gene sequences in the same tissue revealed a negative result.The possible but previously unknown relationship between esophageal achalasia and coinfection with HIV and HCV, also described as neurotropic viruses, will be discussed.

INTRODUCTION: Since 2003, immunoglobulin preparations have been approved for subcutaneous (s.c.) use in Germany. Although all our adult patients on intravenous (i.v.) substitution were offered to switch to s.c. home therapy, approximately half of them refused to change. METHODS: To evaluate patients' attitude towards s.c. home therapy, a questionnaire was developed and sent to 125 patients. Questions had to be answered by ticking numbers on a Likert scale from 1 (not at all) to 8 (very much). Four scales of the Freiburg Personality Inventory (FPI) were added. From the 70 questionnaires returned (56%), 61 could be analysed (i.v. n = 28, s.c. n = 33). RESULTS: The i.v. treated patients were afraid of being more busy with self-administration (6.9 +/- 2.1). This was not a serious concern in the s.c. treated group (3.6 +/- 1.8, p < 0.001). Many i.v. treated patients worried about severe adverse reactions at home (4.7 +/- 2.8), but patients in the s.c. group did not (1.7 +/- 1.0, p < 0.001). The statement "I dislike to puncture myself" reached 5.3 +/- 2.7 points in the i.v. treated group, but only 2.0 +/- 1.1 (p < 0.001) in the s.c. treated patients. As main reason, patients on i.v. substitution considered s.c. therapy as inconvenient (48%). Secondly, they were afraid of side effects (31%). All patients on s.c. therapy appreciated the new treatment (7.2 +/- 1.0). Main advantage for them was an increase of flexibility (6.6 +/- 1.6). The FPI displayed lower values for s.c. treated patients in the scales "Physical Complaints" and "Emotional Lability". CONCLUSION: Those patients who had changed to s.c. therapy were highly satisfied. However, others preferred to stay on i.v. treatment for different reasons. Perception of inconvenience, anxiety of side effects, but also personal traits may play a role.

OBJECTIVE: To investigate whether in rheumatoid arthritis (RA) patients the immunological changes induced by adrenaline are different from healthy controls (HC). METHODS: Fifteen female RA patients and 14 HC were infused with 1 micro g/kg adrenaline over 20 min. Blood was drawn before, immediately after, and 1 h after the end of infusion. Lymphocyte subpopulations, cytokine production and natural killer cell cytotoxicity were determined. RESULTS: Subjects exhibited mild cardiovascular changes with no differences between patients and controls. CD16(+)CD56(+)CD3(-) NK cells increased by a factor of 5.7, CD3(+) T cells by 1.5, monocytes by 1.6 and PMN by 1.2 in both groups. The numbers of IL-8- and IL-10-producing monocytes were higher in patients and presented a larger increase after infusion. NK cytotoxic activity was higher in RA patients and increased after infusion in both groups. Activated monocytes and T cells were preferentially recruited in patients and controls. Values returned to baseline 1 h later. CONCLUSION: We describe an altered response to adrenaline in patients with RA with both pro- and anti-inflammatory effects. Additionally, activated T cells and monocytes recruited to the peripheral blood may influence disease activity.
