WHO statistics indicated that as of October 1, 1991 there were 418,403 acquired immunodeficiency syndrome (AIDS) patients in the world, and an estimated 5-10 million persons infected with the human immunodeficiency virus (HIV) were at risk of developing AIDS. 50% of AIDS victims have died. It has been reported that after 1 year of clinical use HIV could develop resistance to AZT (azidothymidine), the only effective drug used worlwide and recommended for clinical use by the US government. AIDS has also been treated by acupuncture and moxibustion which recent experiments have associated with improving immune function and enhancing resistance to disease. The American scientists Smith and Naomi Rabinowitz used acupuncture and moxibustion in the clinical treatment of AIDS from 1982 to 1988 when they treated 350 patients with AIDS and AIDS related complex. 1 advanced case with Kaposi's sarcoma and signs of hemorrhage was significantly improved after treatment. Traditional Chinese medicine (TCM) has been used successfully in treating cholera, syphilis, epidemic encephalitis, influenza, and hepatitis with a great variety of clinical treatment measures and experiences. In recent years the treatment of AIDS by TCM using herbs and their extracts has been increasing. Dr. Yu of Santa Barbara, California, Hospital, in cooperation with Dr. Chen of China, successfully treated on AIDS patient with Chinese herbal medicine. The patient was still living and well more than 2 years later when another 24 cases which were not treated with TCM died during the same period. In China there are no special laboratories dealing with the prevention and treatment of AIDS, although scientific HIV research could benefit from such activities. On the other hand, foreign scientists and Chinese abroad have accomplished a significant amount of relevant research.

Aztreoman (SQ 26,776, AZT), a synthetic monobactam antibiotic, was applied clinically in the field of obstetrics and gynecology. AZT was administered by intravenous drip infusion for 6 to 8 days at a daily dose of 2 g divided in 2 times to 5 cases. Klebsiella in 1 case with puerperal endometritis, Enterococcus, Propionibacterium and Bacteroides in each 1 case with pyometra was isolated. The clinical effect of Klebsiella was excellent. Bacteroides in 1 not-examined case was good. Enterococcus and Bacteroides with pyometra was not effective. Side effects were observed in 2 cases. One case with eclampsia arised LDH and A1-P in serum and 1 case with hepatitis arised GOT and GPT in serum.

Hepatitis is a common complication of human immunodeficiency virus (HIV) disease in children. Often a distinct pathogen cannot be identified. Therefore, by exclusion, one must consider HIV the direct pathogen. Zidovudine (AZT) has not been used as a treatment for HIV-positive children with presumed HIV-induced hepatitis because of the potential of this medication to exacerbate preexisting hepatitis. We have used AZT to treat an 8-month-old female with severe HIV-induced hepatitis and have achieved complete remission with this regimen. For some HIV-positive children with HIV-induced hepatitis, AZT may be the drug of choice to resolve hepatic inflammation caused by this virus.

The woodchuck hepatitis virus (WHV) and its natural host, the Eastern woodchuck (Marmota monax), have been established as a model of hepatitis B virus (HBV)-induced disease. Several published studies have used this experimental animal model system to demonstrate potential antiviral therapies for chronic HBV infections. However, there has been little comparative information available on compounds used in clinical anti-HBV studies in WHV-infected woodchucks, thereby making interpretations of the potential relative effectiveness of new antiviral agents in humans more difficult. In this report, using a series of placebo-controlled studies, we compared the relative effectiveness of several nucleoside analogues that have been used in clinical trials for the treatment of chronic HBV infection against WHV replication in chronically infected woodchucks. Adenine-5'-arabinoside monophosphate (Ara-AMP [vidarabine]), ribavirin, (-)beta-L-2',3'-dideoxy-3'-thiacytidine (3TC [lamivudine]), and famciclovir (oral prodrug of penciclovir) induced depressions in viremia and intrahepatic WHV-DNA replication that were consistent with their relative effectiveness in anti-HBV human clinical trials. As observed in HBV-infected patients, 3' azido-3'-deoxythymidine (AZT [zidovudine]) had no effect on WHV replication in these studies. These experimental results more firmly establish chronic WHV infection in woodchucks as an accurate and predictive model for antiviral therapies against chronic HBV infection in humans and provide a baseline for comparative antiviral effects of other experimental antiviral agents in the WHV/woodchuck model system.

A case study is presented of a 28-year-old, HIV-infected male with hepatic dysfunction of unknown etiology. After failure on AZT and 3TC, the patient was prescribed d4T, 3TC, and nevirapine. After three weeks of treatment, the patient had poor appetite, bloating, and fever. Blood chemistries, diagnostic imaging, and hepatitis and CMV serologies were all performed, with no clear findings. Since there had been reports of liver dysfunction from nevirapine, all medications were ceased, and the patient's condition improved. The role of antiretroviral agents, particularly nevirapine, in liver dysfunction is explored. Contraindications in prescribing this drug, particularly for patients with impaired liver function or current alcohol or drug abuse, are also discussed.

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.

While it appears that protease inhibitors in combination therapies are saving lives, questions continue: (1) which combinations of protease inhibitors and other antiretroviral agents are most effective in restoring immune function, (2) how these combinations can be used most effectively, and (3) what is the best time to start using them? An evaluation is presented on the immunological value of specific drug cocktail combinations and a comparison of the best and worst drug combinations and the reasons for this assessment. It indicates that Norvir is the most effective of all four protease inhibitors in preventing opportunistic infections, lymphomas, and cancers. D4T and 3TC are the safest and most effective of the nucleosides for preventing or remitting opportunistic infections when used with protease inhibitors. Rescriptor is the most therapeutic of the two non-nucleoside reverse transcriptase inhibitors in increasing absorption of protease inhibitors. The best drug combination therapies are listed as follows: Norvir plus Rescriptor; Norvir plus D4T; Norvir plus 3TC; Norvir, Rescriptor, and D4T; Norvir, Rescriptor, and 3TC; Norvir, D4T, and 3TC; and Crixivan or Viracept plus Rescriptor plus either D4T or 3TC. The worst drug combination therapies are listed as follows: AZT plus ddI (used in combination with a protease inhibitor); AZT or ddI or Combivir (used in combinations with a protease inhibitor); and any two protease inhibitors used together in any person with active hepatitis or elevated liver enzymes or impaired kidney function.

Viral hepatitis and human immunodeficiency virus (HIV) infection are important causes of mortality and morbidity in patients treated by haemodialysis (HD). Both are further promoted by the characteristic immunological dysfunction that develops in renal failure and interferes with the patient's ability to eliminate these viruses. The hepatotropic viruses A through G remain the causative agents in 60 to 80% of hepatitis. But, as far as HD is concerned, hepatitis B virus (HBV) and hepatitis C virus (HCV) are the two most important organisms responsible for almost all the patients' morbidity. In HD, both patients as well as staff are at a high risk of acquiring hepatitis B infection. The prevalence of HBV in the dialysis population in India is reported to range between 3.4% and 42%. The acute course of the infection is often anicteric and peak transaminase concentration is significantly less than in patients with normal renal function. Up to 60% of dialysis patients with HBV infection develop chronic hepatitis with persistence of hepatitis B surface antigen (HBsAg) and infectivity. The risk of transmission of HBV infection due to blood from one patient to another is mostly because of inadequate precautions taken by the dialysis staff. Combined therapy with interferon (6-10 million units) three times a week and lamivudine (100-300 mg/day) would be more effective in controlling viral replication. The most important modality for prevention of HBV infection is induction of immunity by hepatitis B vaccination. Administration of 40 microg doses at months 0, 1, 2 and 6 is the most rapid immunogenic schedule. The prevalence of HCV in HD patients ranges from 6% in the United Kingdom to 60% in Poland and Eastern Europe, 8-36% in North America. HD patients in different parts of India exhibit high anti-HCV positivity (12.1%, 45.2%, 33.3% and 41.9%) in various studies. The incidence and prevalence of HCV infection among patients on dialysis in developed countries are steadily declining because of (i) reduction in post-transfusion HCV infection, (ii) infection control measures to prevent nosocomial infection. Among HD patients with HCV infection, serum alanine aminotransferase (ALT, SGPT) levels are elevated in only 4 to 67% patients who are positive for anti-HCV, in only 12 to 31% patients with HCV RNA and only in one-third of those with biopsy proven hepatitis. Number of blood transfusion, duration of HD treatment, and mode of dialysis are important risk factors. Patient to patient transmission of HCV occurs in HD units by needle stick injury, breakdown in standard infection control practices, physical proximity to an infected patient, dialysis machines, dialysis membranes and HD ultrafiltrate and reprocessing of dialyser. The prevalence of HIV infection in dialysis populations varies according to different countries and geographic areas, 0% and 13% in 1990 and 1995 respectively. There was no evidence of transmission within the centre transmission, from patient to patient or patient to staff. Antiretroviral therapy is the corner-stone of the HIV infection in end stage renal disease (ESRD). Most commonly, zidovudine (AZT) has been used in these patients. Currently recommended dose of 200 mg three times a day is probably safe in these patients.

The hepatitis C infection is highly prevalent among HIV-infected patients. As a direct consequence of the increased survival of these patients in the HAART era, liver disease and its long-term complications have became a genuine health problem in these patients. The treatment of chronic HCV hepatitis is associated with several secondary effects, hiperlactacidemiae/lactic acidosis is one of the most dangerous. It appears to be related with the association of ribavirin and ddI, d4T or AZT. These are three cases of hiperlactacidemiae/lactic acidosis collected during the first twelve months of treatment with pegylated interferon and ribavirin in University Hospital of Guadalajara.

Accidental exposure from blood/body fluid of patients is a risk to healthcare workers (HCWs). Percutaneous injury is the most common method of exposure to blood-borne pathogens. A policy was formulated at our institute, a tertiary care centre in central Mumbai, and we report a six-year (1998--2003) ongoing surveillance of needlestick injuries. Of the 380 HCWs who reported needlestick injuries, 45% were nurses, 33% were attendants, 11% were doctors and 11% were technicians. On source analysis, 23, 15 and 12 were positive for Hepatitis B surface antigen (HBsAg), human immunodeficiency virus (HIV) and hepatitis C virus (HCV), respectively. Immediate action following potential exposure included washing the wound with soap and water, encouraging bleeding and reporting the incident to the emergency room. Analysis of the source of injuries revealed that known sources accounted for 254 injuries, and unknown sources from garbage bags and Operating Theatre instruments accounted for 126 injuries. Most needlestick injuries occurred during intravenous line insertion (N=112), followed by blood collection (N=69), surgical blade injury (N=36) and recapping needles (N=36). Immediate postexposure prophylaxis (PEP) for HCWs who sustained injuries with hepatitis-B-virus-positive patients included booster hepatitis B immunization for those positive for antiHBs. A full course of immunization with hepatitis B immunoglobulin was given to those who were antiHBs negative. All staff who sustained injury with HIV were given immediate antiretroviral therapy (AZT 600 mg/day) for six weeks. Subsequent six-month follow-up showed zero seroconversion.
