It is critical to take HIV medications, particularly protease inhibitors, exactly as prescribed to reduce the risks of developing resistance. The Food and Drug Administration (FDA) recently approved a new drug, Combivir, a combination of 3TC (lamivudine) and AZT in one tablet. Combivir works by interfering with the HIV life cycle to prevent it from replicating, and is taken twice a day with or without food. Patients with low body mass, hepatitis, or liver or kidney disease should not take Combivir. Blood counts need to be monitored regularly when taking this drug. Potential side effects include headache, nausea, fatigue, diarrhea, nasal congestion, or flu-like symptoms. A phone number is provided for more information on Combivir.

Lisa Capaldini, a physician who treats patients with HIV-related fatigue, discusses symptoms, diagnosis techniques, and treatments of depression, anemia, and various other roots of fatigue in HIV-positive patients. Biochemical depression, caused by abnormal levels of serotonin and norepinephrine in the brain, is easily misdiagnosed or overlooked. Physical and emotional symptoms of depression mirror common effects of HIV such as exhaustion, anger, and irritability. Knowing the history of depression prior to HIV infection, including previous drug abuse and family history of depression, will help to diagnose fatigue. Dr. Capaldini recommends antidepressants provided the condition is properly diagnosed and the side effects are not harmful to the patient. Selective serotonin reuptake inhibitors (SSRI), the most frequently prescribed antidepressants, can cause short term sexual dysfunction. Bupropion and Wellbutrin can be prescribed to avoid this side effect. Psychotherapy can be effective if therapists are familiar with HIV disease and can distinguish between symptoms brought on by behavior, addictive habits, or pre-existing depression. Consideration also must be given to drug interactions, particularly with the antiretrovirals ritonavir and delavirdine, which can cause seizures or disturb cardiac rhythm. Anemia is most noticeable after physical exertion, and symptoms are more evident based on the increased rate that red blood cells move out of the normal range. To determine the course of treatment, physicians need to clarify the cause of anemia. Anemia can be caused by drugs, vitamin deficiencies, or other nutritional problems. Adrenal insufficiency, methemoglobinemia, and malnutrition are also causes of fatigue. Diagnosing fatigue due to hepatitis B or C, rather than HIV, can be achieved by measuring hepatitis levels and observing T cell counts and viral load. Dr. Capaldini suggests that proper diet and exercise prevent fatigue from getting worse.

Histamine is a classical, but still interesting inflammatory mediator. Many people have long believed that histamine is derived from mast cells or basophils alone. However, the histamine-forming enzyme, histidine decarboxylase (HDC), is induced in a variety of tissues in response (i) to gram-positive and gram-negative bacterial components (lipopolysaccharides, peptidoglycan, and enterotoxin A) and (ii) to various cytokines (IL-1, IL-3, IL-12, IL-18, TNF, G-CSF, and GM-CSF). HDC is induced even in mast-cell-deficient mice. The histamine newly formed via the induction of HDC is released immediately and may be involved in a variety of immune responses. Reviewing our work and that of Schayer and Kahlson, the pioneers in this field, lead us to the conclusion that nowadays we need to understand that histamine can be produced via the induction of HDC by a mechanism coupled with the cytokine network. We call this histamine "neohistamine", to distinguish it from the classical histamine derived from mast cells or basophils. Neohistamine is involved in physiological reactions, inflammation, immune responses and a variety of diseases such as periodontitis, muscle fatigue (or temporomandibular disorders), stress- or drug-induced gastric ulcers, rheumatoid arthritis, complications in diabetes, hepatitis, allograft rejection, allergic reactions, tumor growth, and inflammatory side effects of aminobisphosphonates.

A 26-year-old female was admitted to our hospital because of arthralgia and general fatigue. On examination, she had malar rash and arthritis. Laboratory data revealed AST, ALT and gamma-globulin elevation, antinuclear antibody and double-stranded DNA antibody positivity, and LE cell phenomenon. Liver biopsy showed marked lymphocytic infiltration and slight fibrosis in the portal areas. She was diagnosed with lupoid hepatitis, and also satisfied the criteria for SLE including malar rash, arthritis, immunologic disorder and antinuclear antibody. She was administered prednisolone, after which AST and ALT decreased. She developed psychosis and her electroencephalogram showed diffuse slow waves corresponding to psychosis by SLE. Lupoid hepatitis is frequently associated with various systemic manifestations. However, only a few cases of lupoid hepatitis satisfying the criteria for SLE associated with psychosis have been reported.

Patients with chronic hepatitis C virus (HCV) infection frequently report fatigue, lassitude, depression, and a perceived inability to function effectively. Several studies have shown that patients exhibit low quality-of-life scores that are independent of disease severity. We therefore considered whether HCV infection has a direct effect on the central nervous system, resulting in cognitive and cerebral metabolite abnormalities. Twenty-seven viremic patients with biopsy-proven mild hepatitis due to HCV and 16 patients with cleared HCV were tested with a computer-based cognitive assessment battery and also completed depression, fatigue, and quality-of-life questionnaires. The HCV-infected patients were impaired on more cognitive tasks than the HCV-cleared group (mean [SD]: HCV-infected, 2.15 [1.56]; HCV-cleared, 1.06 [1.24]; P =.02). A factor analysis showed impairments in power of concentration and speed of working memory, independent of a history of intravenous drug usage (IVDU), depression, fatigue, or symptom severity. A subgroup of 17 HCV-infected patients also underwent cerebral proton magnetic resonance spectroscopy (1H MRS). The choline/creatine ratio was elevated in the basal ganglia and white matter in this group. Patients who were impaired on 2 or more tasks in the battery had a higher mean choline/creatine ratio compared with the unimpaired patients. In conclusion, these preliminary results demonstrate cognitive impairment that is unaccounted for by depression, fatigue, or a history of IVDU in patients with histologically mild HCV infection. The findings on MRS suggest that a biological cause underlies this abnormality.

In infectious diseases and during inflammation, anorexia, loss of body weight, malaise, fatigue and depression are induced. These symptoms are correctively called 'sickness behaviors', and the central actions of cytokines play a role in their induction. The loss of body weight in cancer cachexia is also a result of development of sickness behaviors. It has been reported that the administration of NSAID ibuprofen to patients with cancer cachexia improves the loss in body weight. We studied the effect of NSAID on the loss of body weight by using rodent sickness behavior models. We have reported that sickness behaviors such as anorexia, decrease in body weight, and loss of locomotor activity are induced in concanavalin A (Con A)-induced mouse hepatitis and carbon tetrachloride-induced rat hepatitis. Zaltoprofen is a non-steroidal anti-inflammatory drug (NSAID) causes potent inhibition of cyclooxygenase-2 with fewer side effects on the gastrointestinal tract. Zaltoprofen improves the loss in body weight in both Con A-treated mice and carbon tetrachloride-treated rats. These results suggest the possible application of zaltoprofen for the treatment of sickness behaviors including loss of body weight occurring in cancer cachexia.

A study by Dr. Nagiba Abdulghani, conducted for the University of London School of Hygiene and Tropical Medicine, reports that in almost 2/3 of the cases of maternal death during childbirth in North Yemen, the children died within 1 year of their mothers. The maternal mortality ratio in North Yemen is 753 per 100,000 live births. The study included 224 maternal deaths in 10 hospitals between May, 1987, and April, 1989. 9 out of 10 mothers who died were illiterate. Only 1/5 had received prenatal care. The inaccessibility of health services, the poor quality of care and facilities, and a lack of faith in a system that humiliates women were given as reasons for failure to seek medical care. Causes of death in order of frequency were hepatitis, hemorrhage, infection, and toxemia. 3/4 of the women died postpartum. 1/5 of the babies were stillbirths. 1/5 of the mothers had a history of maternal complications. 1/5 had chronic disease. 2/3 of the women had begun their pregnancies within 1 year of their last childbirth. 1/2 of the women had symptoms ranging from vomiting and fatigue to jaundice and vaginal bleeding. Recommendations of the study included: 1) programs to prevent and treat hepatitis and; 2) an information, education, and communication (IEC) community campaign on the signs of maternal complications. Personnel should also continue their training and research activities.

Six patients presented with clinical, biochemical and histological evidence of severe hepatitis after taking herbal remedies. One patient required urgent liver transplantation for fulminant hepatic failure after the brief use of black cohosh. Five patients took a combination of herbs and presented with jaundice, fatigue and pruritus. Healthcare providers and members of the public should be aware of the potential adverse effects of these remedies.

Patients with chronic hepatitis C frequently report tiredness, easy fatigability, and depression. The aim of this study is to determine whether hepatitis C virus (HCV) replication could be found in brain tissue in patients with hepatitis C and depression. We report two patients with recurrent hepatitis C after liver transplantation who also developed severe depression. One patient died of multiorgan failure and the other, septicemia caused by Staphylococcus aureussis. Both patients had evidence of severe hepatitis C recurrence with features of cholestatic fibrosing hepatitis. We were able to study samples of their central nervous system obtained at autopsy for evidence of HCV replication. The presence of HCV RNA-negative strand, which is the viral replicative form, was determined by strand-specific Tth-based reverse-transcriptase polymerase chain reaction. Viral sequences were compared by means of single-strand conformation polymorphism and direct sequencing. HCV RNA-negative strands were found in subcortical white matter from one patient and cerebral cortex from the other patient. HCV RNA-negative strands amplified from brain tissue differed by several nucleotide substitutions from serum consensus sequences in the 5' untranslated region. These findings support the concept of HCV neuroinvasion, and we speculate that it may provide a biological substrate to neuropsychiatric disorders observed in patients with chronic hepatitis C. The exact lineage of cells permissive for HCV replication and the possible interaction between viral replication and cerebral function that may lead to depression remain to be elucidated.

We describe the case of an 87-year-old woman who presented to Tokyo Kousei Nenkin Hospital because of appetite loss and general fatigue. Multiple liver masses and Borrmann type 2 gastric tumor were detected. A clinical diagnosis of hepatocellular carcinoma and gastric cancer was made based on the patient's high levels of serum alpha-fetoprotein (AFP; 490 200 ng/mL) and protein induced by vitamin K absence or antagonist-II (PIVKA-II, 2284 mAU/mL). The patient's general condition worsened gradually and she died 42 days after admission. Autopsy revealed that the predominant histological structure of the gastric tumor was trabecular or sheet-like, although a tubular structure was also found. Venous invasion was prominent. Immunohistochemically, the tumor tissue was positive for AFP and a few tumor cells were positive for PIVKA-II. The histological appearance and immunohistochemical features of the hepatic tumors resembled that of the gastric tumor. This case was pathologically diagnosed as AFP- and PIVKA-II-producing gastric carcinoma with multiple liver metastases. When tumors are found in the stomach and liver and serum PIVKA-II level is abnormally high, the possibility of PIVKA-II-producing gastric cancer with liver metastasis should be considered, especially when hepatitis virus markers are negative and liver cirrhosis is not present.
