Fatigue is a highly prevalent symptom experienced by persons who live with chronic illness, including those with renal failure who require maintenance haemodialysis. Fatigue, however, is a non-specific and invisible symptom and is a phenomenon that is poorly understood by health care professionals. This study examined the symptom of fatigue as experienced by a group of 39 adult haemodialysis patients. The theory of unpleasant symptoms formed the conceptual framework for the study. A descriptive correlational design was utilized to examine fatigue from an inductive approach, considering relevant physiological, psychological and situational variables based on a review of the literature. Data were collected using a structured self-report questionnaire and biochemical data from retrospective monthly blood tests. The results of the study indicated that high levels of fatigue are experienced, with correspondingly low levels of vitality, in all the areas measured - general fatigue, physical fatigue, reduced motivation, reduced activity and mental fatigue, by adult haemodialysis patients. Individual variation was noted in the dimensions of fatigue predominantly expressed. Fatigue was significantly associated with the presence of symptoms such as sleep problems, poor physical health status and depression. No associations between fatigue and the biochemical and situational variables measured were noted. Further examination of the data revealed complex relationships between the physiological and psychological factors examined. Depression was significantly associated with physical health status, sleep problems, symptoms and anxiety. Correlations were also noted between symptoms and poor physical functioning, sleep problems and depression. Based on the results, a revised version of the theory of unpleasant symptoms relating to fatigue is presented.

A 23-year-old female patient presented with hirsutism and fatigue nine months after delivery. Endocrine assessment showed high testesterone, DHEA-S and androstenedione levels. Abdominal computed tomography and ultrasonography revealed the presence of a large tumor in the right renal region. Right adrenalectomy was performed resulting in a diagnosis of a functional adrenal tumor. Pathological examination showed a steroidogenically active tumor. Adjuvant chemotheraphy was administered postoperatively. At three months following surgery all endocrinological tests normalized, but liver metastases were detected by abdominal CT. Eight months after the operation the patient died of hepatic and renal failure. Androgen-secreting adrenal tumors are seen very rarely, yet the prognosis is poor due to their agressive nature.

Mitochondrial and metabolic myopathies constitute a group of disorders characterised by abnormal muscular metabolism of energy. Most of these disorders are genetically transmitted. Recent progress in the field has led to spectacular advances in their classification and the understanding of the mechanisms involved, particularly in mitochondrail myopathies. Diagnosis can be made et any age; the patient can present manifestations that can be misleading for the clinician. Lipid myopathies and glycogenoses usually present as a myopathic syndrome associated with cramps, spasm and myalgia, with fatigue on effort. Acute episodes of rhabdomyolysis on effort can occur, with an attendant risk of renal failure. Mitochondrial myopathies have multi-organ manifestations and muscular involvement is not always at the forefront. Although diagnosis may be suggested by clinical factors, it should be confirmed by teams and laboratories that specialize in muscular disorders.

Every patient with end-stage renal failure, at any age and whatever the type of renal disease, is a legitimate candidate to maintenance dialysis. Contraindications are infrequent and based purely on medical considerations, such as profound and irremediable alteration of physical and/or mental condition. In patients regularly managed dialysis is decided electively on the basis of laboratory criteria in the absence of clinical uremic manifestations other than fatigue, anorexia or nausea. The most widely accepted criterion is a level of creatinine clearance estimated by the Cockcroft-Gault formula between 7 and 10 mL/min/1.73 m2. Psychological preparation of the patient to dialysis is essential and should not be delayed until the advanced stage. Medical preparation involves prophylactic vaccination against virus B hepatitis and creation of a native arteriovenous fistula when hemodialysis is the scheduled option. Every patient should receive in time clear and complete information on the various technical methods of dialysis, in order to allow him an informed choice.

A 56-year-old man with persistently elevated liver enzyme levels, fatigue, lethargy and a 9.0 kg weight loss over six months underwent a percutaneous liver biopsy that demonstrated multiple granulomas. Screening serologies were positive for histoplasmosis, and he was started on itraconazole treatment. He returned to hospital the same night with coffee-ground emesis and in Addisonian crisis requiring parenteral steroids and intensive care unit support. An abdominal computed tomography scan revealed bilaterally enlarged, nonenhancing adrenal glands suggestive of infarcts, presumed secondary to histoplasmosis. Treatment was initiated with amphotericin B, and Histoplasma capsulatum was cultured from his urine and cerebrospinal fluid. A serum immunodiffusion test was also positive for both H and M bands, indicating active infection with Histoplasmosis species. His serum and urine samples were also weakly positive for the antigen. Despite complications of renal failure, pneumonia and congestive heart failure, he recovered with medical therapy and was discharged home to complete a prolonged course of itraconazole therapy. While hepatic granulomas often reflect an occult disease process, the cause may remain undiscovered in 30% to 50% of patients despite exhaustive investigations. H capsulatum is an uncommon cause of granulomatous liver disease, and with its protean clinical presentation, a high index of suspicion is needed to make the diagnosis and avoid the potentially high fatality rate associated with disseminated infection.

Omeprazole is a proton pump inhibitor that is used commonly in the treatment of acid-peptic disorders. Although omeprazole is generally well tolerated, serious adverse effects such as renal failure have been reported. Thus far, 17 cases of acute interstitial nephritis (AIN) secondary to omeprazole have been described. Another case of AIN is described in a 36-yr-old woman presenting with nausea, vomiting, weight loss, and a rising serum creatinine concentration. Omeprazole therapy had ceased 2 wk before admission. AIN was diagnosed by renal biopsy and corticosteroid therapy was initiated. After 4 wk of therapy the serum creatinine concentration had normalized. Among the reported cases in the literature, AIN was diagnosed after an average of 2.7 months of therapy with 20-40 mg of omeprazole daily. Recurrence was universal on rechallenge. Common symptoms included fatigue, fever, anorexia, and nausea. The classic triad of fever, rash, and eosinophilia was uncommon. Typical laboratory features included hematuria, proteinuria, pyuria, eosinophilia, and anemia. Management consisted of withdrawal of omeprazole and corticosteroid therapy in some patients. All but one patient recovered normal renal function. Corticosteroid therapy was well tolerated and may have been beneficial.

Allogenic blood transfusion may be required for the treatment of anemia due to a hematologic disease, the consequences of chemotherapy or other circumstances, such as haemorrage and/or surgery. Transfusion becomes indispensable to prevent the side effects of anemia, such as hypoxia, palpitations, tachycardia, cardiac ischemia and fatigue. However, frequent transfusions can cause several acute problems such as hemolysis, anaphylactic shock and septic shock but also chronic problems such as iron overload (hemochromatosis), alloimmunisation and metabolic disturbances. Each of these complications can produce serious consequences and could even be sometimes fatal. Therefore we should recognise, prevent and if necessary treat all these hazards. Our article emphasises the potential chronic problems. For hemochromatosis, an iron chelator (deferoxamine) should be administered. In the presence of allo-immunisation the more compatible ABO blood group must be chosen and blood products be eliminated by filtration, when there has been blood reaction. When an allo-graft of hematopoitic tissues is considered an irradiation of blood products is necessary. Research is being carried out to develop substitute products for transfusion (haemoglobine solutions) or molecules acting on the syntheses of haemoglobine (butyrate arginine). The efficacy of erythropoitine, (EPO) is well recognised for stimulation of haemoglobine syntheses in renal failure and oncology.

A Japanese girl aged 13 years with myeloperoxidase anti-neutrophil cytoplasmic antibodies(MPO-ANCA)-associated glomerulonephritis(GN) progressed to end-stage renal failure after 7 years' clinical observation. She had been suffering from recurrent disease flare associated with serum MPO-ANCA elevation(i.e. 153 EU/ml, 208 EU/ml and 358 EU/ml, maximum at each of the episodes, normal < 10 EU/ml). Each flare was treated successfully with prednisolone combined with cyclophosphamide and azathioprine. However, her renal function gradually deteriorated, and peritoneal dialysis(PD) was initiated 7 years after the onset of the disease. During the clinical course, no extrarenal manifestations were observed. Due to subsidence of the serum MPO-ANCA titer(10 EU/ml) after starting PD, prednisolone and azathioprine were tapered thereafter. Her daily urine volume was preserved at approximately 600 ml at that time. She suddenly developed fatigue with severe anemia, oliguria and hypertension 4 months after discontinuation of immunosuppressive therapy. The serum titer of MPO-ANCA increased to 100 EU/ml. These clinical observation suggests that disease flare may occur in selected patients with MPO-ANCA-associated GN, who develop end-stage renal failure requiring PD. Although recurrent flare associated with an increased serological activity in a proportion of patients with lupus nephritis who have received dialysis has been reported to date, to our knowledge, a similar clinical observation in the MPO-ANCA-associated GN has not been reported. Selected patients with the disease should be followed with close observation after undergoing dialysis.

Two cases of alcoholics associated with rhabdomyolysis and acute renal failure were reported. Case 1 was a 67-year-old male who had complained of general fatigue and generalized muscle pain. He had drunken and slept outdoor in winter until he was found. Laboratory data on admission showed remarkable elevation of muscle enzymes (AST, LDH, CPK) and serum levels of myoglobin, BUN, and Cr. He was treated with hemodialysis because of acute renal failure caused by rhabdomyolysis and recovered from renal failure. Case 2 was a 50-year-old male who had been unconscious and suffered from muscle weakness. He had drunken and slept in the bed for several days without eating any food until he was found by his sister. Laboratory data on admission showed remarkable elevation of muscle enzymes and serum levels of myoglobin, BUN, and Cr. It also showed hypoglycemia and hyponatremia. He developed into acute renal failure caused by rhabdomyolysis, but had a good clinical course without hemodialysis. The rhabdomyolysis of case 1 might have been caused by alcohol and sleeping outdoor in winter. That of case 2 might have been caused by alcohol and pressure necrosis due to immobility for several days in his bed.

Despite maximal intensive care, mortality of acute fulminant hepatic failure is high: 60%-75% in several studies. In addition patients with chronic liver insufficiency suffer from a bad quality of life: all patients suffer from fatigue; symptoms of hepatic encephalopathy, jaundice, and itching are often present. Analogous to artificial kidney treatment in patients with renal failure, an artificial liver assist device is needed not only to bridge patients with fulminant hepatic failure to liver transplantation or own liver regeneration, but also to improve the quality of life of patients with chronic liver insufficiency. Several modalities of artificial liver support are under investigation, like plasma exchange, haemodialysis, haemadsorption, albumin dialysis, liver cell transplantation, and the bioartificial liver. Artificial livers based on only supportive detoxification function do not show significant improvement of survival in controlled studies. Bioartificial liver support systems have also the potential to support hepatic synthetic functions. Bioreactors can be charged with freshly isolated or cryopreserved porcine hepatocytes, but also by human hepatoma cell lines. Several uncontrolled studies in humans show safety of such a treatment, even by using porcine cells. Transmission of porcine endogenous retrovirus to recipients has not been found. Furthermore, beneficial effects have been reported on symptoms of hepatic encephalopathy, on the height of intracranial pressure and on hemodynamic parameters. By using porcine cells immunological problems (e.g., serum sickness) can be expected during treatments longer than one week. However, "proof of the pudding" in the sense of improvement of survival is not yet available. The creation of a "liver dialysis unit" in the near future depends mainly on the development of well-differentiated immortalized human hepatocytes. Some progress in this field has already been obtained.
