To date no treatment exists that is able to eradicate the hepatitis C virus from the body discount kamagra soft 100 mg with mastercard erectile dysfunction surgical treatment options. As a result discount kamagra soft 100 mg line impotence diagnosis code, drug levels in the patients blood- stream undergo significant fluctuations in a two-day rhythm cheap 100 mg kamagra soft mastercard erectile dysfunction zurich, giving rise to side effects and limit efficacy purchase kamagra soft 100 mg otc impotence 21 year old. It is also considered that fluctuation is instrumental promoting the appearance of resistant viruses. Thanks to a carefully selected pegylation with the appropriate bond with the protein,Pegasys is broken down much more slow- ly than simple interferon and therefore remains active in the body longer. This has several advantages for patients: Firstly, Pegasys only has to be given once weekly. Secondly, the dose does not have to be adjusted gradually at least not to the same degree according to the patients age, hepatic status and renal function, a time-consuming process. Thirdly, interferon levels in the bloodstream are subject to less fluctuation, making the side effects more tolerable and improving patient compliance. First approved in 2002, Pegasys quickly became the internation- al market leader in the hepatitis C sector. The drug was also the first pegylated therapeutic protein in the world to be approved for the treatment of chronic hepatitis B. A new drug class: Therapeutic antibodies form a relatively new therapeutic antibodies drug class that was only made possible by modern biotechnology. These Y-shaped proteins bear on their two short arms two identical regions that recognise a specific foreign structure. The long stem of the molecule interacts with other components of the immune sys- tem, which then initiate destruction of the intruders. In 1972 Csar Milstein and Georges Khler, who later received the Nobel Prize, found a way to produce copies of identical antibody molecules in unlimited amounts. Within a few years these so-called monoclonal antibodies had revolutionised bio- logical research, allowing any desired molecule to be reliably identified and marked. However, it took more than 20 years for monoclonal antibodies to find widespread use in therapy. Not until the late 1990s did researchers succeed in exploiting the specificity of monoclonal antibodies for therapeutic purposes. For example, monoclonal antibodies can be designed to bind to specific molecules and block their disease-causing effects. However, drug developers were unable to use antibodies ob- tained from standard mammalian (usually mouse) cells. Because the molecules differ in structure from one species to the next, mouse antibodies proved to be of very limited benefit in humans. Re- searchers therefore turned their attention to what are known as chimeric and humanised antibodies, where only the recognition regions are based on mouse genes. It is now possible to insert all the human genes required to produce antibodies into laboratory Main avenues of research 45 A new drug class: therapeutic antibodies Mouse Chimeric Humanised Human Each antibody bears on its two short arms identical regions render them harmless. Whereas early therapeutic anti- that recognise a specific foreign structure, to which they bodies were still partly derived from mouse genes (yellow bind. This principle is exploited in therapeutic antibodies in segments), therapeutic antibodies of the latest generation order to recognise pathogenic and other substances and are indistinguishable from their human counterparts. Immunisation Gene transfer Mouse with human Ig genes Human monoclonal antibodies Fully human therapeutic antibodies are obtained by infect- production of immunoglobulins (Ig) with the target for the ing a transgenic mouse that carries human genes for the antibodies that one wishes to produce. As a result, medical science now has at its disposal an arsenal of therapeutic antibodies that are structurally identical to their natural counterparts in the human body. Example MabThera: A good example of a highly effective chimeric an- hope for patients with tibody is the Roche product MabThera/Rituxan lymphoma (rituximab). The target protein of this therapeutic antibody is a receptor located on the surface of B lymphocytes (white blood cells), which in lymphomas grow uncontrollably. The antibodies bind to the cancer cells, marking them out for destruction by the bodys immune system. At the same time rituximab makes the cells more susceptible to certain forms of chemotherapy, thus improving the survival chances of patients who previously had no further therapeutic options fol- lowing unsuccessful chemotherapy. A turbocharger for the Therapeutic antibodies such as rituximab help immune system the patients immune system to home in on dis- eased target cells. Main avenues of research 47 Enhanced immune response: modified therapeutic antibodies 120 Engineering of antibody 100 80 60 40 Wildtype antibody 20 Engineered negative 0 control antibody 0 10 20 30 40 50 Antibody concentration (ng/ml) Specifically modified therapeutic antibodies can induce a five to eight times stronger immune response (e. The next drug The next step was to link therapeutic antibodies generation: small with small molecules to form what are known as molecule conjugates small molecule conjugates. Antibodies have a disadvantage that they share with other thera- peutic proteins: they are too bulky to penetrate into the interior of cells. Potential targets are therefore limited to molecules lo- cated outside of or on the surface of the bodys cells. By contrast, many conventional, chemically synthesised small molecule drugs can readily pass through the cell membrane to targets within the cell or even the cell nucleus. Small molecule conjugates combine the specificity of therapeu- tic proteins especially antibodies with the broad target range of small molecules. To produce them, researchers have de- veloped complexes, or conjugates, consisting of therapeutic antibodies coupled to low-molecular-weight drugs. In such con- jugates the antibodys role is to ferry the actual drug directly to its target in the body. Drugs commonly used to destroy cancer cells also attack healthy cells in the body. Once Co plexbinds this occurs, the entire conju- tocell gate is internalised in the cell. In cancer cells the anti- body is digested and releases the small molecule, which Cancercell then destroys the diseased cell. In this way cancer cells Cancercell orzelle can be specifically targeted and adverse effects on Co plexcarries drugintocell healthy cells can be minim- ised. If Entireco plexinsidecell the findings from tests are borne out, the latest gener- ation of these drugs could Cancercell signal a breakthrough not Drugkills cancercell only in cancer therapy but in many other therapeutic Conjugated antibodies combine the specificity of thera- areas where medical science peutic proteins with the broad target range of small mole- has hitherto had to contend cules. The antibodies target a specific structure on the with severe side effects surface of cancer cells. Once the antibody has located its target and bound to it, the conjugated small molecule drug caused by the unspecific is released, penetrates the cancer cell and kills it. As well as the therapeutic possibilities it offers, modern biotechnology can lead to novel ways of combating diseases such as diabetes, cancer and rheumatic diseases. For example, early and specific diagnosis, and also tests that can monitor treatment and the course of an illness, can result in more effective treatment of patients. The biotechnology market Medical science can only be as good as its under- grows apace standing of disease processes. The more doctors know about the causes of diseases, the more ef- fectively they can deal with them. This realisation may sound simple, but translating it into practice remains difficult, be- cause the critical part of treatment is often finding the right diagnosis. It is precisely in this area that biotechnology has made tremendous strides in recent decades. Thus, for example, alleviating pain should not be the only goal when treating patients with chronic pain. It is only when the source of the pain has been identified that steps can be taken to counter it in the long term. Yet pain patients in particular often have to undergo veritable medical odysseys as a result of uncer- tain diagnoses, failed treatments and ever increasing pain.

If the bilirubin is primarily unconjugated discount 100 mg kamagra soft with amex erectile dysfunction treatment medicine, hemolysis or genetic defects are implicated kamagra soft 100 mg low price impotence treatment after prostate surgery. In adults kamagra soft 100mg line erectile dysfunction reversible, Gilberts syndrome is an inherited genetic disorder of impaired bilirubin conjugation. Particularly at times of physiologic stress, a mild unconjugated hyperbilirubinemia may occur. Management Management of the specific disorders causing jaundice is contained in the chapters on the hepatobiliary and pancreatic systems. Mechanisms With significant liver disease (cirrhosis), ascites is a result of activation of the renin- angiotensin-aldosterone system and portal hypertension. Increased portal pressure leads to transudation of fluid from the capillaries in the portal system to the peritoneal cavity. Signs and Symptoms Ascites most commonly presents with increasing abdominal girth. Diaphragmatic elevation or a pleural effusion (ascites fluid tracking into pleural space) can lead to shortness of breath. Clinical examination reveals a distended abdomen and bulging flanks on inspection. Smaller amounts of fluid may be detected on ultrasound when clinical signs are absent. One should look for other signs of portal hypertension, such as dilated abdominal wall veins or splenomegaly. Differential Diagnosis Newly developed ascites must have a diagnostic aspiration (paracentesis) to determine the albumin level, cell count and cytology. The gradient is calculated by subtracting the ascites albumin from the serum albumin. If the gradient is high (>11 g/L), then the ascites is due to portal hypertension. If the gradient is low (>11 g/L), then the ascites is not from portal hypertension. A low gradient results from ascites that is high in protein, so that the ascites albumin level is close to that of the serum. Ascitic fluid may become infected, in which case the white blood cell count will be elevated (>250 neutrophils/uL) in the fluid. Most cases also require addition of a diuretic such as spironolactone and/or furosemide. If ascitic fluid reaccumulates despite these measures, aspiration of large quantities of ascites fluid or large volume paracentesis may be First Principles of Gastroenterology and Hepatology A. The black colour of melena is the result of degradation of blood by intestinal bacteria. Obscure bleeding is defined as bleeding of unknown origin that persists or recurs after negative initial endoscopies (colonoscopy and upper endoscopy). Another risk factor for some patients is a reduced level of consciousness due to shock or hepatic encephalopathy. Some patients may require supplemental oxygen or even intubation for airway protection and/or assisted breathing. It is important to remember that, hemoglobin (Hb) and hematocrit (Hct) may not be low at presentation. Over the ensuing 3648 hours, most of the volume deficit will be repaired by the movement of fluid from the extravascular into the intravascular space. Only at these later times will the Hb and Hct reflect the true degree of blood loss. In a predisposed individual, anemia can lead to congestive heart failure or angina. Other important data includes a prior history of peptic ulcer disease, history of abdominal surgery (e. The hemodynamic status should be interpreted in light of the patients abilities to compensate for hypovolemia. In a young and fit adult, the presence of a resting or orthostatic tachycardia should be interpreted as a sign of significant volume loss, while the loss of an equivalent blood volume in an elderly or debilitated subject would more likely be manifested by hypotension or shock. Once supportive measures have been undertaken, the patient should be assessed with a view towards identifying the source of bleeding (ie. The pigmentation of the stool will depend on the length of time in transit along the bowel. In determining the likely source of bleeding, the clinician needs to interpret the patients manifestations of bleeding in conjunction with the hemodynamic status. In the absence of spontaneous passage of stools, a digital rectal examination to determine the stool color will be most informative. If the bleed is due to a peptic ulcer, upper endoscopy allows stratification of rebleed risk based on the appearance of the ulcer. Early upper endoscopy is done if there are signs of a brisk bleed, a variceal bleed is suspected, the patient is older or has numerous comorbidities. Wireless capsule endoscopy involves ingestion of a pill sized camera to take pictures of the small bowel. Enteroscopy involves a long scope inserted from the mouth to examine the proximal small bowel. Balloon enteroscopy is a newer endoscopic technique in which total endoscopic examination of the small bowel is possible. Description When an abdominal mass is discovered on physical examination, one must define its nature. Using a systematic approach often permits the identification of the mass before the use of sophisticated tests. Important Points in History and Physical Examination Important clues in the history and general physical examination may help to identify the enlarged viscus. For example, in a young patient presenting with diarrhea, weight loss and abdominal pain, finding a right lower quadrant mass would suggest inflammatory bowel disease. However, an abdominal mass may be discovered during physical examination of an asymptomatic individual. Certain observations made during the abdominal examination may be helpful (See also Section 20). A practical approach is to divide the abdomen into four quadrants (See Section 20. Starting from the principle that an abdominal mass originates from an organ, surface anatomy may suggest which one is enlarged. In the upper abdomen a mobile intraabdominal mass will move downward with inspiration, while a more fixed organ (e. Auscultation Careful auscultation for bowel sounds, bruit or rub over an abdominal mass is part of the systematic approach. Defining the Contour and Surface of the Mass This is achieved by inspection, percussion and palpation. In the absence of ascites, ballottement of an organ situated in either upper quadrant more likely identifies an enlarged kidney (more posterior structure) than hepatomegaly or splenomegaly. Differential Diagnosis The following suggests an approach to the differential diagnosis of an abdominal mass located in each quadrant: 18.
