A total of 8.37% of the 1195 patients treated at NDTB Centre with DOTS under RNTCP between January 2002 to June 2003 presented with adverse drug reactions. Patients showing any sort of adverse reactions were studied in detail by personal interviews and a semi-structured questionnaire. The profile of patients presenting with adverse reactions showed that majority of the patients (53%) had gastrointestinal reactions, the commonest presenting complaint being nausea and vomiting. General aches and pains were complained by about 35% and giddiness was the presenting complaint in 27% irrespective of the use of streptomycin, although giddiness was observed more often in Category II patients (59%). Skin rash and itching was complained by about 17% of patients and 11% complained of arthralgia, while only 1% had hepatotoxicity during treatment. Majority of the adverse reactions (67%) were observed within the first four weeks of treatment and only 0.25% of patients treated with DOTS had interruption of treatment for short periods.

Smoking causes a variety of adverse effects on organs that have no direct contact with the smoke itself such as the liver. It induces three major adverse effects on the liver: direct or indirect toxic effects, immunological effects and oncogenic effects. Smoking yields chemical substances with cytotoxic potential which increase necro-inflammation and fibrosis. In addition, smoking increases the production of pro-inflammatory cytokines (IL-1, IL-6 and TNF- alpha) that would be involved in liver cell injury. It contributes to the development of secondary polycythemia and in turn to increased red cell mass and turnover which might be a contributing factor to secondary iron overload disease promoting oxidative stress of hepatocytes. Increased red cell mass and turnover are associated with increased purine catabolism which promotes excessive production of uric acid. Smoking affects both cell-mediated and humoral immune responses by blocking lymphocyte proliferation and inducing apoptosis of lymphocytes. Smoking also increases serum and hepatic iron which induce oxidative stress and lipid peroxidation that lead to activation of stellate cells and development of fibrosis. Smoking yields chemicals with oncogenic potential that increase the risk of hepatocellular carcinoma (HCC) in patients with viral hepatitis and are independent of viral infection as well. Tobacco smoking has been associated with suppression of p53 (tumour suppressor gene). In addition, smoking causes suppression of T-cell responses and is associated with decreased surveillance for tumour cells. Moreover, it has been reported that heavy smoking affects the sustained virological response to interferon (IFN) therapy in hepatitis C patients which can be improved by repeated phlebotomy. Smoker's syndrome is a clinico-pathological condition where patients complain of episodes of facial flushing, warmth of the palms and soles of feet, throbbing headache, fullness in the head, dizziness, lethargy, prickling sensation, pruritus and arthralgia.

Primary biliary cirrhosis (PBC) is an autoimmune disease, characterized by chronic biliary duct destruction, which mainly affects women aged between 35 and 45 years. Prolonged liver inflammation can cause scarring, leading to cirrhosis. The most common first clinical manifestations are pruritus, asthenia or jaundice, but most patients remain asymptomatic. PBC can be associated by itself with arthralgia, but polyarthritis and synovitis are exceptional. PBC is often associated with other non-hepatic autoimmune diseases, especially primary Sjogren's syndrome, which may favour articular involvement. PBC and rheumatoid arthritis (RA) have been suggested to coexist in 1.8 to 5.6% of patients with PBC, but data supporting this association are scarce. We report two cases of such an association. Both of these patients presented severe erosive RA. We discuss the therapeutic management of these patients, taking into account hepatic involvement and drug toxicity.

Oral mucositis (OM) is an extremely debilitating side effect of certain high-dose chemotherapy and radiotherapy regimens. It is especially prevalent in patients with haematological malignancies who undergo myeloablative therapy and autologous haematopoietic stem cell transplantation (HSCT). Severe erosion of the lining of the oral cavity can make patients' everyday activities, including eating, drinking, swallowing, and talking, difficult or even impossible. Palifermin (Kepivance) was approved in Europe in 2005 for both prevention and treatment of this painful condition. It works at the epithelial level to help protect cells in the mouth and throat from the damage caused by chemotherapy and radiation, and to stimulate growth and development of new epithelial cells to build up the mucosal barrier. In the pivotal clinical trial, palifermin reduced the incidence, severity, and duration of severe OM. Palifermin was also well-tolerated; common adverse reactions reported included rash, pruritus, erythema, edema, pain, fever, arthralgia, mouth or tongue disorders, and taste alteration. In this article, nurses who are skilled in caring for patients undergoing HSCT review their clinical experience with palifermin, sharing practical advice about its reconstitution, dosing, and administration. By familiarising themselves with the use of palifermin, nurses can influence a shift in clinical practice away from OM symptom management to the more satisfactory situation of protecting patients against severe OM.

Health-related quality of life (HRQoL) has become an important outcome measure in patients with chronic liver disease (CLD). In this article, an overview is given of the most common measurement instruments of HRQoL, determinants of HRQoL in patients with CLD, and current developments in the implementation of routine measurement of HRQoL in daily clinical practice. Well-developed generic instruments of HRQoL are the Short Form-36 (SF-36), the Nottingham Health Profile (NHP) and the Sickness Impact Profile (SIP). Well-developed liver disease-specific HRQoL instruments are the Hepatitis Quality of Life Questionnaire (HQLQ), the Chronic Liver Disease Questionnaire (CLDQ), the Liver Disease Quality Of Life Questionnaire (LDQOL ), and the Liver Disease Symptom Index 2.0 (LDSI 2.0). Commonly used HRQoL measures in cost-effectiveness studies are the Health Utilities Index (HUI), Short Form-6D (SF-6D) and the EuroQol-5D (EQ-5D). HRQoL of patients with chronic liver disease has been shown to be impaired, with patients with hepatitis C showing the worst HRQoL. Disease severity, pruritus, joint pain, abdominal pain, muscle cramps, fatigue, depression and anxiety have been associated with HRQoL in patients with CLD. Recently, studies assessing the feasibility and effectiveness of measuring HRQoL in daily clinical practice have been performed, generally showing positive results regarding the discussion of HRQoL-related topics, but mixed results regarding the added value of actual improvement in HRQoL. Furthermore, logistic and attitudinal barriers seem to impede successful implementation. Nevertheless, given the importance of HRQoL in liver patients, we should persist in measuring and subsequently improving HRQoL in clinical practice.

Hemodiafiltration with larger amounts of substitution fluid offers an optimal way to remove uremic substances. Hemodiafiltration could be indicated for all hemodialysis patients. Large observational studies have shown an association of a lower mortality risk with hemodiafiltration using more than 15 liters of substitution fluid. Specific indications should be considered because hemodiafiltration has been reported to be effective against hyperphospatemia, malnutrition, insomnia, irritability, restless-leg syndrome, polyneuropathy, anemia, itching and joint pain, and may prevent dialysis-associated amyloidosis. In this chapter, hemodiafiltration prescriptions concerning blood and dialysate fl ow, infusion rate, vascular access and frequency are detailed.

Numerous skin and mucosal manifestations were observed during the 2005-2006 chikungunya epidemic in Reunion Island. A prospective study was carried out in a consecutive series of 212 patients treated for chikungunya at the emergency unit of the Saint-Pierre Hospital in Reunion Island from March 8 to April 27, 2006. Diagnosis of chikungunya was suspected in patients with fever and joint pain and confirmed by RT-PCR and/or serology (IgM). Skin involvement was observed in 50% of patients. It consisted of exanthema with patches of healthy skin mainly on the trunk and limbs that sometimes displayed diffuse, congestive and even edematous features. Itching was reported in some cases (19.3%) and was sometimes isolated. Peeling of the skin was observed in a few cases but remained uncommon in adults. Outcome was rapidly favorable in most cases sometimes with scaling or persistence of dyschromic patches. These findings suggest that chikungunya should be suspected in subjects presenting a febrile rash while in an endemic areas or after returning from a tropical zone.

Interferon-alpha-n1 (lymphoblastoid interferon-alpha) is a nonrecombinant 'natural' interferon derived from lymphoblastoid cells exposed to Sendai virus. In common with endogenous and recombinant interferon-alpha molecules, interferon-alpha-n1 has antiviral, immunomodulatory and antiproliferative properties. Interferon-alpha-n1 shows some efficacy in immunocompetent adults with well-compensated chronic viral hepatitis B. Rates of complete virological response (defined as an absence of detectable hepatitis B virus-DNA in the serum) ranged from 5 to 79% of adults who received various dosage regimens of interferon-alpha-n1 in monotherapy trials. Clearance of hepatitis B 'e' antigen was reported in 5 to 70% of patients treated with the drug. Spontaneous virological responses occurred in 0 to 48% of untreated patients. The clinical efficacy of interferon-alpha-n1 in patients with chronic hepatitis B is not improved by concomitantly administered deflazacort, zidovudine or levamisole, but may be increased by a course of corticosteroid pretreatment in some patients. Interferon-alpha-n1 also shows therapeutic benefit in adults with chronic hepatitis C. Complete biochemical responses (defined as normalisation of serum ALT levels) were achieved in 27 to 60% of adult patients treated with the drug, whereas spontaneous normalisation of serum ALT levels occurred in up to 11% of untreated patients. Responses to interferon-alpha-n1 were temporary in 27 to 78% of treatment responders but were sustained in 6 to 40% of patients. Emerging data delineating baseline factors predictive of a positive response to interferon-alpha-n1 treatment may aid in the selection of patients with hepatitis B or C most likely to benefit from treatment with this drug. Most patients receiving interferon-alpha-n1 experience a transient 'influenza-like' syndrome during the first week of treatment. The syndrome, which is dose related and alleviated by paracetamol (acetaminophen), is characterised by fever, chills, and arthralgia. Dose-limiting adverse effects occurring during longer term interferon-alpha-n1 therapy include fatigue, myalgia, headache, depression, pruritus and seizures. Neutropenia and thrombocytopenia may also occur during interferon-alpha-n1 treatment. Autoimmune thyroid disease may develop in up to 9% of patients treated with interferon-alpha-n1 for >or=6 months. At present, interferon-alpha-n1 and the recombinant forms of interferon-alpha are the only drugs available for the treatment of adults with well-compensated hepatitis B or C. Interferon-alpha-n1 produces moderate response rates in adults with well-compensated chronic hepatitis B or C. Thus, it is positioned alongside recombinant interferon-alpha products as a useful first-line treatment option for patients with chronic hepatitis B or C.

The risk of oral NSAID including Cox-2 inhibitors to cause gastrointestinal, renal or cardiovascular adverse events related to systemic drug exposure could be reduced by local application. But only few long-term studies have been published to show safety and efficacy for long-term use of topical NSAID s. Diractin (formerly IDEA-033) is a viscous, aqueous formulation for epicutaneous application of ketoprofen based on ultra-deformable, self-regulating carrier (Transfersome). This multiple-dose, open label study with treatment periods up to 18 months included 402 patients with joint pain, musculoskeletal pain, stiffness or soft tissue inflammation (age of 61.4+/-11.5 years). Most of the patients suffered from osteoarthritis (OA) of the knee (68.9%). Diractin was applied epicutaneously up to twice daily with a maximum dose of 220 mg ketoprofen per a maximum of 2 application sites. The mean pain score at baseline was 5.4+/-.4 on a 10 point categorical scale. During the study the pain score progressively improved up to week 36 (3.5+/-1.9) without a substantial further change during the rest of observation period of up to 18 months. The reduction of pain scores between week 0 (baseline) and at all later visits was statistically significant (P<0.0001). Patients also reported an improvement of quality of life on the EUROQoL. The majority of treatment related adverse events were skin and subcutaneous tissue disorders with the highest frequency reported for erythema (16.7%) and pruritus (2.0%). Systemic ketoprofen exposure remained low throughout the study period with plasma concentrations of less than 1% of what was reported for a single, standard oral dose of 200 mg ketoprofen. There were no occurrences of treatment related serious adverse events and no remarkable changes in laboratory values or vital signs. In summary, Diractin provided adequate pain relief with a good safety and tolerability profile when used for up to 18 months (72 weeks).

Hepatitis C is caused by the hepatitis C virus (HCV) infection. According to World Health Organization data, 3% of the world population (approximately 170 million people) is infected with HCV; in Poland there are over 700,000. Over 70% of those infected manifest no symptoms in the acute phase of the disease, and in about 70-80% the acute phase progresses into a chronic form. Patients with symptoms in the acute phase of HCV infection most commonly present with unspecific signs and symptoms that may develop in other viral liver infections, e.g. malaise, fatigue, abdominal pain, mild hepato- and splenomegaly and arthralgia. These symptoms usually persist for 2 to 12 weeks. In the chronic phase a subset of patients complain of malaise, nausea, abdominal pain and itching. With time, chronic hepatitis C may develop into liver cirrhosis. The basic diagnostic methods in HCV infection involve determination of anti-HCV antibodies using the ELISA immunoassay and examination of HCV-RNA with the RT-PCR method. The current treatment of HCV infection involves administration of pegylated interferon a and ribavirin over a period of 48 weeks in HCV-1 genotype infection, and 24 weeks for HCV-2 and 3 genotypes. Effectiveness of therapy depends on the HCV genotype. HCV elimination can be achieved in 78% of patients with HCV-2 and 3 genotypes, and in 55% of patients with HCV-1 genotype.
