A study of human rabies immune globulin manufactured by the Thai Red Cross.

This is a prospective post marketing study of 4496 patients presenting with severe animal bites in a canine rabies endemic region. They received human rabies immune globulin manufactured from volunteer blood donors at the National Blood Center of the Thai Red Cross Society at Bangkok. All patients also received a full course of tissue culture rabies vaccine. Only three subjects reported an adverse reaction (redness and itching at the immune globulin injection sites). None of the patients died during the subsequent 18 month follow up period.

Acute acalculous cholecystitis in leptospirosis.

The authors present three patients with acalculous cholecystitis seen at a tertiary care center in Bangkok. The first patient was explored surgically because peritonitis was suspected. The two other patients were treated conservatively with antibiotics and supportive care, and they recovered fully. The diagnosis of leptospirosis was confirmed by increasing antibody titers in three patients and by blood culture in one patient. Leptospira were not detected in the surgical specimen. Leptospirosis is a systemic disease that can present with a multitude of symptoms and signs including right upper quadrant pain mimicking cholecystitis. A high level of awareness and appropriate laboratory studies should allow early diagnosis and may prevent unnecessary surgical intervention.

Melioidosis, an environmental and occupational hazard in Thailand.

Melioidosis is a tropical environmental hazard that causes acute and chronic pulmonary disease, abscesses of the skin and internal organs, meningitis, brain abscess and cerebritis, and acute fulminant rapidly fatal sepsis. It is more common among adults, individuals with diabetes, and individuals with chronic renal disease, but it can occur in normal hosts and children. Burkholderia pseudomellei is the most prevalent cause of community-acquired pneumonia, liver and splenic abscess, and sepsis in northeastern Thailand. Melioidosis can reactivate years after primary infection and result in chronic or acute life-threatening disease. With increasing worldwide travel and migration, patients may present in nonendemic countries with reactivation melioidosis decades after leaving an endemic region. We discuss seven selected patients presenting with this disease to a tertiary care facility in Bangkok between 1995 and 1997. Awareness should allow early diagnosis and treatment, which can lead to decreased morbidity and mortality.

Safety and efficacy of purified Vero cell rabies vaccine given intramuscularly and intradermally. (Results of a prospective randomized trial).

OBJECTIVES: To determine adverse reactions as a result of pre- and post-exposure rabies vaccination, using the conventional intramuscular, and reduced dose intradermal regimens and purified Vero cell rabies vaccine. DESIGN: A prospective and randomized study of patients exposed to rabies and of subjects in need of pre-exposure rabies vaccination. SETTING: A metropolitan rabies control center in a canine rabies endemic country. PATIENTS: 1198 subjects were recruited between May, 1994 and March, 1996. They were divided into four groups. Patients with suspected or proven rabies exposures were given the vaccine intramuscularly using the conventional regimen, or intradermally using the World Health Organization approved Thai Red Cross schedule. Human or equine rabies immune globulin was administered where indicated. Pre-exposure and post-exposure vaccine recipients were divided randomly into two groups each and given the vaccine either by the intramuscular or intradermal schedules. MEASUREMENTS: All local and systemic adverse reactions were recorded and statistically analyzed. RESULTS: Pruritus at injection sites was the only significant local reaction. It was more common in the intradermal groups. Low-grade fever, the only significant adverse systemic event, was more common in the intramuscular groups and was noted in 8% of all subjects. Eighty-four patients bitten by proven rabid animals were found to be alive and well 3 years later. Forty-four of these had received the intramuscular and 40 the intradermal postexposure regimens with human or equine immune globulin injected into wounds on the first day of treatment. CONCLUSIONS: Purified Vero cell rabies vaccine is safe, carries a very low adverse reaction rate and is effective in preventing rabies in severely exposed subjects when used with human or equine rabies immune globulin.

Rabies in Thailand.

The prevalence of canine and human rabies in Thailand has decreased significantly during the last decade. This has been associated with an increasing number of human post-exposure treatments. Educational efforts, mass vaccination of dogs and cats and the use of safe and effective vaccines have all made an impact. The proportion of fluorescent antibody positive dogs, among those examined for rabies averaged 54% indicating that rabies is still a major public health threat. Canine rabies vaccination is not usually performed in animals < 3 months old. However, this study revealed that 14% of rabid dogs were < 3 months old and 42% were < or = 6 months old. This is the age group most likely to interact with humans and other dogs. Our study also supports the World Health Organization's recommendation that observing suspected rabid dogs for 10 days is an adequate and safe practice.

Postexposure treatment of rabies in Pakistan.

To evaluate compliance with current World Health Organization (WHO) guidelines for postexposure treatment (PET) of rabies, we interviewed all animal bite victims seeking treatment on the same day of each week from 28 December 1994 through 18 January 1995 at the Civil Hospital of Karachi (Pakistan), a major referral center. Of the 143 patients studied, 109 (76%) sustained bleeding transdermal bites (WHO category III). Overall, wounds were not washed with soap or an antiseptic in 69% of victims. All victims received 5% sheep brain-derived vaccine, and only three of the 109 victims with category III bites received rabies immune globulin. PET of rabies in Karachi was deficient by all WHO standards. Although there is a great urgency to improve PET, it will remain a costly and inefficient method of controlling rabies. Reduction of rabies reservoirs is required to decrease human deaths due to rabies in Pakistan and other developing countries in which canine rabies is endemic.

Problems with rabies postexposure management: a survey of 499 public hospitals in Thailand.

Rabies is still a major public health problem in Asia. The incidence of known annual human cases in India alone has recently been revised from 20,000 to 30,000, and over 500,000 patients are given some form of postexposure rabies treatment. Only China, Peninsular Malaysia, Singapore, and Thailand are reporting a significant decrease in the prevalence of this disease in humans. Over 150,000 courses of postexposure treatment (PET) are given in Thailand every year. To determine remaining barriers to further reduction of the number of human rabies deaths, we carried out a questionnaire study of government hospitals throughout the Kingdom.

Venomous snakebite in Thailand. I: Medically important snakes.

Thailand has an abundance of venomous snakes. Among the neurotoxic family Elapidae, there are three species of the genus Naja (cobras), three of the genus Bungarus (kraits), and the king cobra of the genus Ophiophagus. Other Elapidae snakes in Thailand include sea snakes and Asian coral snakes of the genus Calliophis. They have potent venoms but rarely bite humans. Tissue and hemotoxic snakes are represented by family Viperidae, subfamilies Viperinae and Crotalinae. They remain an occupational hazard for farmers and rubber tappers, causing serious morbidity but only rare deaths, since competent treatment is now widely available throughout Thailand. Purified equine antivenin is manufactured locally for the monocled and Siamese spitting cobras (Naja kaouthia and N. siamensis), king cobra (Ophiophagus hannah), banded krait (Bungarus fasciatus), most green pit vipers (Trimeresurus sp.), Malayan pit viper (Calloselasma rhodostoma), and the Siamese Russell's viper (Daboia russelli siamensis).
