Given the current and future public health, social and economic consequences, the prevention and treatment of allergic reactions to foods is a major challenge that must be addressed. Copyright 2011 World Allergy Organization 48 Pawankar, Canonica, Holgate and Lockey Patients presenting with symptoms linked to food should threatening) is estimated to be greater in toddlers (5-8%) than in undergo a diagnostic work-up to identify the offending food adults (1-2%). The epidemiological knowledge of food allergy and clarify a complex spectrum of disease, which ranges from is crucial to the design of preventive strategies7. Causal Symptoms diagnosis is achieved only with a positive oral food challenge Clinical symptoms of food allergy present with a wide range against placebo, followed by a negative, open food challenge, of immunoglobulin (Ig)E and non-IgE mediated clinical carried out in a facility capable of dealing with cardiopulmonary 8 3 syndromes (Table 8). Once the suspected food allergy is confrmed, occur immediately or within 1-2 hours of ingestion of a food, dietary management plans can be drawn up in collaboration whereas non-IgE-mediated reactions present later. Table 8 Presentations of food allergy Prevalence Around 11-26 million members of the European population IgE-mediated Mixed Non-IgE mediated are estimated to suffer from food allergy4. If this prevalence (IgE and non-IgE) is projected onto the worlds population of 6,659,040,000, it Angioedema Eosinophilic Protein-losing gastroenteropathies enteropathy translates into 220-250 million people; a huge global health burden. Although we know the worldwide time trends in the Nausea and vomiting Gastroesophageal Dietary protein refux proctocolitis prevalence of symptoms of asthma, allergic rhinoconjunctivitis Rhinoconjunctivitis Dietary protein Constipation and eczema in childhood, there is no study assessing the enterocolitis prevalence of food allergy and its time trends. The problem is Laryngeal edema Colic Heiner syndrome complicated by the fact that only a small proportion of cases Systemic Anaphylaxis Pulmonary of perceived food allergy. In Oral itching and the 1980s, 30% of women reported that they or some member abdominal pain of their family had an allergy to a food product. From the mid Diarrhea 1990s, self-reports began to be compared with challenge Wheeze, Asthma confrmed diagnoses; reported incidences between 12. This was proven when a reactions such as urticaria and angioedema, food allergy plays prevalence of between 2. Thus, we can refer to two separate food allergy, with hens egg, cows milk, soy and wheat accounting allergy epidemiologies. Self-reported food allergy: this does not represent the Gastrointestinal manifestations: In the gastrointestinal tract true epidemiology of food allergy, but gives an indication IgE-mediated manifestations include mouth and lip pruritus, of the potential demand for allergy medicine. It is helpful abdominal pain, vomiting and diarrhea shortly after ingestion to health service providers in planning for the demand of culprit foods. In non-IgE-mediated manifestations the causal for specialist allergy services, as well as for food industry relationship to foods is more diffcult to detect. Challenge-confrmed food allergy frequency: representing are the same as those observed in primary gastroesophageal the real clinical dimension of the problem. Eosinophilic esophagitis is characterized Food allergies are a cause of particular concern in young by eosinophilic infammation of the esophagus. Allergic proctitis usually presents by 6 involving heat treatment, may allow sensitized individuals months of life in breastfed or occasionally formula-fed infants. Thus in many cases milk elimination or change of formula, but the pathological the avoidance of cooked foods may not be necessary. The most allergenic triggers are ubiquitous and also been suggested as a cause of constipation in infants and nutritionally valuable proteins, thus, a dieticians advice is children. Cross-reactivity is possible, but multiple food allergies a variety of respiratory tract symptoms that generally involve are rare. Since extensive elimination diets are seldom IgE-mediated responses, including rhinorrhea and wheezing. Thus, 90% of infants who are allergic Generalized manifestations: the most severe manifestation to cows milk may tolerate it by the end of their third year, of food allergy may be anaphylaxis. With an increasing whilst half their peers who are allergic to egg do not react frequency, this recently re-defned condition11 greatly adds to the to it at the same age. Clinically, food allergy is responsible for 30,000 anaphylaxis episodes/ this translates into the necessity of reviewing all dietary year12, leading to 2,000 hospitalizations and 200 deaths/ interventions and avoidance strategies with the patient or year. The mainstay of treatment of these often unpredictable their parents for clinical re-evaluation on a periodical basis. Education of teachers and of health personnel is also Hospitalization necessary in order to ensure the correct use of epinephrine the major burden of food allergy hospitalizations is from autoinjectors13. Currently, the only treatment available is where between 1993 and 2004 the number of Emergency avoidance of the food/s identifed as allergenic for the individual Department visits for allergic reactions remained stable at patient. Conversely, Hospital discharges with a factor which affects all clinical presentations of food-induced diagnosis related to food allergy increased signifcantly from allergy (including delayed reactions) and atopic dermatitis. However, a series of practical problems in diet therapy should be afforded at the individual level during outpatient consultation: Mortality 1. Most episodes develop in children with an established diagnosis of food allergy and are thus preventable. Fatalities Copyright 2011 World Allergy Organization 50 Pawankar, Canonica, Holgate and Lockey due to food anaphylaxis happen predominantly away from On both the sides of Atlantic, the regulatory problem is now the home which indicates the need to promote public awareness of opposite concern whether too many foods containing trace the problem. Emergency Departments in developed countries amounts of these allergenic foods are being over-labeled may need to be prepared for an increase in this condition in the and whether this may restrict potentially safe food choices next few years18. The legislation does not require the indication of potential contaminants, but many manufacturers are now indicating may contain as a warning of potential Severity of Disease contamination during food preparation. Food allergy reduces self-esteem, infuences the Even in the case of contaminants, excessive eliminations perception of social/emotional roles, infuences behavior of should be avoided. A case in point is lactose, indicated as children, inhibits family activities, and reduces family cohesion a possible cause of adverse reactions in children with cows (2). The literature does not report a single case of high levels of food-specifc IgE-antibodies, suggesting that an adverse reaction to lactose ingestion among children with elimination diets contribute to this burden19. Thus, even if lactose per se can determine severe allergic reactions to cows milk when inhaled by children with severe cows milk allergy21, dietary lactose elimination Drug Use (translating into a blanket ban for these children of not only Food allergy sufferers must use the drugs related to their specifc lactose-containing foods, but also of many pharmaceutical symptoms (asthma, rhinitis, atopic eczema), but the essential preparations, and even toothpastes, which may contain this drug for treating anaphylaxis symptoms is epinephrine. The sugar as an excipient, bulking agent or nutritional supplement) main therapeutic challenge for food allergic patients is dietary is not justifed. Teenagers and young adults meet obstacles unshared by their non-allergic peers, thereby curtailing their quality of life. Financial Burden Individuals with food allergy and their families have to be Children with food allergies present fnancial challenges to their concerned about potential exposures to relevant food allergens parents. Parents with food-allergic children are more likely to in a variety of settings, including restaurants, the work and/or stop working, reduce their work hours, or incur other fnancial school environment, picnics and parties, and during travel. Labeling is an issue of relevance to food allergic or food allergy, found an additional fnancial burden of $482 per consumers because accidental ingestion of allergens in pre year for medical services and prescription drugs22. Other costs packaged processed foods due to labeling ambiguities is are sustained by the food industry. In the European Union, twelve food through product recalls running into millions of Euros, together items are required by law to appear on food labels: cereals with hidden costs associated with the need for comprehensive containing gluten, crustaceans, egg, fsh, peanut, soy, milk allergen management systems of around 30 million for food (including lactose), nuts, mustard, sesame seeds, celery, and manufacturing operations alone23. Directions Thus many of the problems with unlabeled, hidden allergens Many studies are addressing the issues of possible new in the food supply may no longer apply and in particular, the treatments and preventive strategies for food allergy, but we risk that unfamiliar names can hide allergenic foods is now only report here the major trends expected to have a socio minimized. The aim children with the major food allergies (egg, wheat, milk, is both to reduce the risk of major reactions and to avoid nuts, peanut) is not widespread in all countries. In many allergy, where in many countries substitutes are either cases, tolerance induced in desensitized children disappears non-hypoallergenic. Dietary Prevention: Traditionally predicated on the avoidance of food allergens, epidemiological data highlighting the Socio-economic: involvement of the intestinal micro-fora in the development Food allergy is a modifable risk and its only form of management of allergic disease have been used to design strategies to is dietary. Success depends on the modifcation of sources of interfere with the pathogenesis of food allergy using success food-related risk: factors, rather than the exclusion of risk factors. Studies on this approach, defned as proactive in contrast to the Under-rating the food allergy problem (corrected with traditional prohibitionistic approach, have explored the medical education). From a global perspective, there are several tasks to be Ultimately, the empowerment of patients through education, addressed in the feld of food allergy in the immediate future: the guidance of an allergist and dietitian, and support from patients associations may provide optimal risk minimization and quality-of-life-enhancing strategies to be implemented Diagnostic: through all levels of care, in the absence or failure of other Implementation of point-of-care tests to screen for, and approaches. These evidence Education of clinicians in affuent parts of the world in the based guidelines are of the utmost importance to identify recognition of possible food allergy symptoms.

They should be placed in an incubator as soon as possible and within 16 hours of blood collection. Strict quality assurance is necessary to detect unusual patterns in results (such as a spike in the number of indeterminate results due to low mitogen response or high negative control responses), and it is important to run both positive and negative controls with each assay. An indeterminate result implies that the test cannot produce a valid result; often this is because of immune suppression, which leads to lack of T-cell response to the positive control. More recent studies have confirmed this finding and expanded the type of evidence on test reproducibility. The importance of pre-analytical factors, such as the time lapse between blood collection and sample processing and/or incubation at 37 C, was brought out by a recent study in the United 34 States. Compared with immediate incubation, 6 and 12-hour delays resulted in positive-to negative reversion rates of 19% (5/26) and 22% (5/23) respectively. A portion of the variability in test interpretation was associated with manual 59 data entry errors. There is currently no consensus on the exact borderline zone that should be used, and this an active area of debate and research. If results do fall in this borderline zone, care providers could choose to repeat the test, depending on the clinical context and other information available. To facilitate the interpretation of such values, laboratories should provide quantitative results in addition to the dichotomous (positive/negative) results. If portable incubators are used, it is important to make sure that such incubators can accurately stabilize the temperature at 37 C. Laboratories should avoid manual entry of results to avoid additional variability and errors (see Appendix D). However, in high incidence settings there were no consistent differences in the prevalence of positive tests. Thus, further research is needed to identify biomarkers that are highly predictive and can identify 69 latently infected individuals who are at highest risk of disease progression. Only those who would benefit from treatment should be tested, so a decision to test presupposes a decision to treat if the test is positive. This strategy will improve the overall specificity of the testing process in low-risk individuals and may also be cost-effective, as shown in a Canadian 71 study. If results do fall in this zone, care providers could choose to repeat the test, depending on the clinical context and other information available. To facilitate the interpretation of such borderline values, laboratories should provide quantitative results in addition to the dicho tomous (positive/negative) results.

In the initial phase multiple effective drugs are used in combination to achieve the first and second objective. On the basis of results of randomized trials, this phase should last 2 months, and the drugs should preferably be given daily. The second objective is addressed by the continuation phase, during which only two drugs are usually given. The length of this phase is variable, depending on indicators of risk of relapse, on the drugs given in the initial phase and on the results of pre-treatment drug susceptibility testing. Optimal therapy to achieve all three treatment objectives for patients of all ages, with disease at any site, should be guided by the results of drug susceptibility testing. If drug suscepti bility testing results are pending then more drugs may be needed to ensure that at least two are likely to be effective. In the initial intensive phase, particularly when bacillary load is high (see below), three likely effecttive drugs should be used to prevent emergence of drug resistance. Therefore, it is recommended that all necessary measures be taken to avoid patient drop-out or loss to follow-up, or interruption of drug supply. If patients experience adverse events, an alternative therapy should be initiated promptly. Practitioners who cannot guarantee adequate monitoring and supervision of therapy should refer the patients immediately to centres where this can be assured. However, to understand the rationale for many of the principles above it is useful to understand how drug resistance develops. Therapy with a single drug will lead to the uninhibited growth of bacilli carrying the mutation to this drug while all 9 other bacilli are eradicated. This means that within 2-3 months of the start of monotherapy all 10 bacteria will carry this mutation, and clinically the patient will be fully resistant to that drug. Fortunately, the mutations to different drugs are independent, so treatment with two drugs will usually mean that the mutants with resistance to one drug are killed by the other drug, unless the 9 total number of bacilli is very high. Using this, and the spontaneous mutation rate, it is possible to calculate the probability that treatment with one, two or three drugs will lead to the emergence of drug resistance as a result of natural or spontaneous mutations, even in a patient who takes all doses properly. Evidence about the action and the role in therapy of each drug comes from in-vitro and animal studies as well as from multiple randomized trials. It is clear that eye toxicity is dose dependent, and its risk is higher at 25 mg/kg than at 15 mg/kg. If these drugs are needed because of intolerance or resistance to first-line drugs, daily therapy is suggested **Initial dosage if renal function is normal. Dosing should be adjusted based on peak and trough serum levels in consultation with a pharmacist. It has very powerful early bactericidal activity, meaning that it is highly effective in rapid killing of bacteria in the first few days. It is also effective in preventing the emergence of resistance, although its role in preventing relapse is unclear. Pyridoxine (vitamin B6) should routinely be added for patients with diabetes, renal failure, malnutrition, substance abuse or seizure disorders or for women who are pregnant or breastfeeding, because of the increased risk of symptoms related to pyridoxine deficiency in these patients. The drug has good bactericidal activity (Objective 1), prevents acquired drug resistance (Objective 2) and is very important in preventing relapse (Objective 3). Current doses are based on studies performed in the 1960s, when the lowest effective dose was used because of the high cost of the drug. When the results are available, recommendations for use of the drugs as first-line therapy may change. Injectables the injectables include streptomycin, amikacin, kanamycin and capreomycin. On the basis of expert opinion, the Canadian Thoracic Society suggests that of all the injectables amikacin is preferred for use in Canada, because it is available in most hospitals, providers (including pharmacists) are familiar with the drug, and drug concentrations are readily available, reducing risk of toxicity. There are few situations in which one can confidently predict such a low likelihood of any resistance, especially since the prevalence of resistance has risen steadily over the last 40 years in all populations with access to treatment. If patients miss a single dose while receiving thrice weekly therapy they effectively receive twice weekly therapy, which is still adequate. If they miss a dose of twice weekly therapy they effectively receive once weekly therapy which is inadequate. The tablets can be crushed and mixed with water, or suspensions of the medications can be prepared to make delivery easier. To prolong therapy in all patients in order to achieve a 3% reduction in relapse would expose many patients needlessly to prolonged therapy. These include having more extensive disease and/or 19 cavities on a chest x-ray in the first 2 months of therapy, being culture-positive after 2 months of 19 20 therapy or having a cavity on chest x-ray at the end of treatment. Many studies have evaluated different schedules of therapy in the continuation phase, after daily therapy for the first 2 months. If a patient receiving thrice weekly intermittent therapy misses a single dose they are effectively receiving twice weekly therapy, which is still acceptable. In theory these formulations should prevent monotherapy from physician or patient error, or patient selection of only some of their medication. If the risk of non-adherence is judged to be low, the lower risk of toxicity may justify the longer therapy. It is suggested that all drugs can be given in normal doses and frequency, but with careful monitoring for toxicity. It is preferable to reduce the frequency of administration of these drugs rather than reduce the doses, as the peak serum concen-trations are key to their bactericidal effects. Monitoring serum concentrations will be very useful to ensure that adequate, yet safe, doses are given. The use of injectables (streptomycin, amikacin, kanamycin and capreomycin) should be avoided if possible in patients with impaired renal function, as these drugs are excreted by the kidney and may cause 1,6 worsening renal function as well as other toxicities. Hence, the standard dosing and schedule are recommended, but patients should be closely monitored, and therapeutic drug monitoring. To date there have been no reports of teratogenicity even though this drug has been given to millions of pregnant women worldwide. The use of injectables (streptomycin, amikacin, kanamycin and capreomycin) is contraindicated because of the effects on the fetus, including eighth cranial nerve palsies, 4 deafness and teratogenic effects. The resulting amounts ingested by the newborn baby will not produce toxic effects. It is important to remember that the amount ingested in maternal milk would not constitute an effective dose for treatment or prophylaxis in a nursing 27 infant, even in a newborn. Most of these drug interactions can be managed by adjusting the dosage according to measured drug concentrations. In some patients the drug interactions are not manageable or could result in serious consequences, such as a patient receiving immune suppressive therapy following solid organ transplantation. Two reviews suggest that prednisone in doses of 40-80 mg/day for 6-12 weeks 31,32 is likely to be effective, but the optimal dose and duration of treatment are not well defined. In a meta-analysis of three small randomized trials of patients with tuberculous pleurisy, corticosteroids resulted in more rapid resolution of symptoms and pleural 33 fluid, but there was no evidence of long-term benefits. Chest radiography should be performed after 2 and 6 months of therapy to assess response, potential complications and risk of relapse. This is best done by providing a 34 comprehensive, patient-centred treatment program.

The process of translating a tool into a different language can be difficult and requires a considerable investment of time and money (Sperber 2004; Acquadro et al. For this 189 reason, the translation process was funded by the School of Nursing, Midwifery and Health, University of Stirling, and it took around three months to complete before the pilot study could commence. However, appropriate translation of the instrument can enhance research quality and validity (Sperber 2004). Selecting the proper translation technique and procedure was a vital step to maintain the equivalence between the two versions of the tool (Cha et al. The translation process was carried out by highly qualified translators (Sperber 2004) to prevent difficulties that might result from tool translation that might threaten the studys validity. Although the back translation was time consuming and expensive, it is important to keep the equivalence of semantic words (meaning), idiomatic expressions and grammatical form between the translated questionnaire and its original source (Guillemin et al. The findings indicate that the Arabic version of the tool can be completed quickly in clinical settings through interviews, even with illiterate patients or those with more advanced disease. This discrepancy may have arisen because different completion methods were used, as participants in the earlier study completed the questionnaire themselves, whilst in this study the participants were interviewed. It could also be that to read the questions in Arabic takes longer than in English. It is therefore recommended that the open ended question be kept in the Arabic version to collect all relevant symptoms experienced by these patients. The foundation of all rigorous research designs is the use of measurement tools that are psychometrically sound (DeVon et al. Validity is one of the 191 most essential characteristics of an instrument and is a prerequisite for quantitative tools and for assuring the integrity of study findings (Polit and Beck 2008). Knowing what type of psychometric properties to look for can be a very important step in proving the tools validity, such as convergent construct validity (DeVon et al. Convergent construct validity is used to determine the extent to which two or more instruments measure the same construct (item) after administration to the same individuals at the same time and under the same conditions (Liobiondo-Wood and Haber 1994; Litwin 1995; McDowell 2006). Correlations indicate whether there is an overlapping between the measurements items, establish whether the tested scales items measure the same concept, and give either redundant or complementary information depending on the magnitude of the association (van der Plas et al. This result means there is moderate overlapping between the provided information by the two tools regarding these items and domains. Also, as was expected, the item of depression correlated with the domain of vitality and the item of hampered depression correlated with domain of mental health, although rs value of both correlations was less than 0. However, rs values of the remaining five correlations that were expected for Table 5-1 were 0. Furthermore, sexual activity had a moderate correlation with role limitation due to emotional problems, and sexual interest had moderate correlation with social functioning. However, it is worth noting that this study investigated sexual health in terms of erectile function among males, but not desire or activates therefore the studys findings cannot be generalised to females sexual health. It is important to highlight that difference in the results between the current study and prior study (van der Plas et al. All the items of symptoms, such as joint pain and hampered of joint pain had a moderate to high correlation with their accompanying items of hindrance of these symptoms. This finding is similar to the previous study by van der Plas in 2004 which found that the correlation value ranged from 0. These results suggest information overlapping between these items and their accompanying items. Additionally, the convergent relationships between all symptom severity items and their accompanying symptom hindrance items showed a strong relationship, rather than with other symptom hindrance items. However, reliability and validity are interrelated criteria for the tool (Polit and Beck 2008). A measuring tool cannot assess what it is intended to measure if it is inconsistent (unreliable) (Polit and Beck 2008). Reliability means to what extent the instrument gives consistent results over time (Liobiondo-Wood and Haber 1994), and whether it is free from measurement error with repeated measures (Waltz et al. The test-retest reliability procedure is conducted by administering the same instrument to the same individuals under the same conditions on two or more separate times to evaluate whether the measurement gives the same results (Liobiondo-Wood and Haber 1994; Litwin 1995; McDowell 2006; Waltz et al. The time interval between the repeated measures depends on the phenomena being measured (Waltz et al. Internal consistency reliability the results of the current study show that the alpha coefficients for the subscales exceeded the acceptable value > 0. The study design was cross-sectional in nature; which involves the collection of data at one time. The disease stage was categorised as patients with compensated or decompensated cirrhosis according to liver disease complications during the year 196 of data collection. However, the strength of the current study is the heterogeneity of the study participants, which included patients from both outpatient and inpatient clinics, as well as males and females from both rural and urban areas in Egypt. The small sample size, from only one hospital, limited the validation that could be carried out, although the initial validity was good. The pilot study was also useful to confirm the feasibility of daily recruitment rates (minimum and maximum), and the expected sample size for the main study. Additionally, it was helpful in identifying issues of concern for the main study such as time of interviews, recruitment strategy and whether three months of field work would be enough to recruit a large enough sample for the main study. This study reinforced the importance of the researcher attending the clinic settings daily and being systematic in the recruitment of a large sample size during the three months. It is also important to acknowledge that the pilot phase findings were strengthened by the diverse range of patients that were recruited. For example, the participants were from a wide age range, males and females from rural and urban regions and with different social backgrounds, allowing a range of perceptions to be obtained. Recruitment rates were monitored and recorded on a daily basis and were accurately maintained through the study. The reasons why patients refused to take part in the study, or indeed withdrew from the interview were recorded. The recruitment phase in the study lasted three months and was conducted from June 199 to August 2011. During this time, 415 patients were identified as being eligible to participate in the study; two of them were not approached because their consultant advised that these patients were too anxious to participate. The total number of participants who gave consent and participated in the study was 401 (Diagram 6-1). The researcher obtained permission from the patient before conducting the interview as to whether her/his relative could be in the room during the interview. The majority of the patients who participated in the study preferred to be interviewed alone. Whilst interviewing the participants to complete the questionnaires some of them felt the need to "explain" their answer. Illustrative quotes from qualitative quotes are seen as a way of illuminating the quantitative results and thus are treated as part of discussion. The participants were Arabic speakers so as a result their quotes were translated into English. The following quote illustrates the interest of the participants to talk about their health status. Female (303) 200 Diagram 6-1: Sample flow diagram 415 patients were identified as being eligible to participate in the study Two were not approached because they were too anxious to participate (Male and Female) 413 persons were invited to take part in the study 12 persons refused to participate in the study Three did not give any reason (Two males and one female) One had a hearing problem (Female) One had a speech problem (Male) Seven did not have time (Males=5 and Females=2) 401 participants gave consent and participated in the study Response rate 96. Only 17% of participants in this study were currently employed, although the majority (90%) were less than 65 years old. There was no significant different between males (compensated = 81, decompensated = 93) and females 2 (compensated = 120, decompensated = 107) disease stage X (1, n = 401) = 1. This question was rated on the 5-point ordinal scale ranging from one "Excellent" to five "Poor". Table 6-5: Perceived general health compared to one year ago as rated by liver cirrhotic patients n = 401 Rating scale of health transition n (%) Much better now than one year ago 12 (3. These factors were socio-demographic characteristics, medical data, disease stage, symptoms experience and perceived adequacy of social support. Using Post-hoc statistical analysis Tukey Bonferroni identified a statistically significant difference between the two age groups [mean difference = 5. The eight domains and the two component summary scores were poorer among unemployed than employed people (p = 0. There were no statistically significant differences between people living in rural and urban regions in Egypt. Factors that were significantly associated with physical health were gender, education, employment status, disease stage, complications of liver disease, comorbidities, symptoms severity and hindrance of daily life due to symptoms. Therefore, it was essential to develop a regression model for each of these dependent variables independently. The following variables were entered all together into the regression analysis to develop Model 1 for physical health and Model 2 for mental health. The significance limit to enter and leave the multiple regression steps was set at p = 0. The first model (Model 1) included symptoms experience (severity and hindrance), the three subscales of perceived social support (spouse, family and friends), socio demographic factors and medical data. This chapter will cover the second and the third aims of this study: Second aim: To explore and describe experienced symptoms (prevalence, severity and hindrance) in Egyptian cirrhotic patients and to identify and evaluate factors associated with symptoms severity and symptoms hindrance (distress). Section I describes the symptoms experience of people with liver cirrhosis and how these symptoms affect their daily activities. It also presents factors that are associated with and predicted symptoms experience. One subscale assesses the severity of various physical and 234 psychological symptoms as well as the social dysfunctional experience over the previous week, which consists of 15 items. The other subscale examines how much peoples daily or social activities are affected by some of these symptoms and it contains 9 items. Additionally, the prevalence of symptoms severity and the prevalence of the impact of symptoms on daily or social activities in patients with cirrhosis are presented. The mean score of the symptoms severity subscale was higher than the mean score of the symptoms hindrance subscale, suggesting that symptoms severity was higher than hindrance of daily life due to these symptoms among these patients. Table 7-2 shows the prevalence of the 15 symptoms that were reported by the patients who answered yes. The majority of the patients had one or more of a wide range of physical and psychosocial symptoms (Table 7-2). On the other hand, jaundice was the only symptom that few of these people experienced (27. The increased score means impaired daily and social activities as a result of symptoms. Some of the patients had one or more of a wide range of physical and psychosocial 237 symptoms that impacted on their daily and social activities (Tables 7-2 and 7-3), such as hindrance of daily life due to joint pain (70. In other words, joint pain and depression were the symptoms that influenced these peoples activities in their daily life most. This suggests that gender, educational level and employment status have a significant impact on the perceived severity of symptoms. Moreover, the limitation in their daily activities because of symptoms was higher in those same groups. Therefore, further statistical analyses (chi-square test) were done to compare these groups. Table 7-5 shows the prevalence of symptoms severity and hindrance of daily life due to symptoms among males and females. There was a significant difference in the types of symptoms experienced between men and women. Women were more likely than men to report symptoms of joint pain, right abdominal pain, decreased appetite, depression, jaundice, memory problems, changing personality and difficulty in managing time (p 0. On the other hand, men were more likely than 238 women to report symptoms of sexuality problems (decreased sexual interest and activity) (p = 0. However, males and females have the same symptoms of worry about the family situation, itching, fear of disease complications and problems in financial affairs. Women were more likely than men to have limitations in their daily life due to this symptom. Therefore, the assessment of symptoms experience showed to include not only the severity of the symptom but also the effect of this symptom on daily life. Table 7-6 presents the prevalence of symptom severity and hindrance of daily activities due to symptom among single and married people. There was a significant difference in the types of symptoms experienced between married and single people. Singles were more likely than married people to report symptoms of joint pain and worry about the family situation (p 0. In contrast, married people were significantly more likely to report a decrease in sexual interest and activity (p = 0. In terms of the impact of symptoms on daily life, single and married people were likely to experience a similar level of impact of symptoms on their daily activities. The proportion of symptoms of right abdominal pain, depression, changing personality, difficulty managing time and jaundice was significantly higher among the unemployed than the employed (p 0. In terms of the impact of symptom on daily life, the prevalence of the impact of joint pain, right abdominal pain, decreased appetite and depression on daily and social activities was higher among the unemployed than the employed (p 0. Table 7-7: the proportion of symptom severity and hindrance of symptom among employed and unemployed Symptom severity Employment status Chi-square p value phi 2 Employed Unemployed (X) coefficient N=68 N=333 n (%) n (%) Itch 30(44. In other words, it seems that the perceived severity of symptoms increases with the progressive stage of cirrhosis. Besides that, the mean score of perceived symptoms severity extensively increased with the increasing number of complications and comorbidity (p 0. This means that there was a significant positive correlation between the number of both comorbidities as well as liver disease complications and severity of symptoms. Table 7-8 shows that severity of symptoms also had a significant positive association with the number of admissions to hospital because of liver disease.
