Frequency of Human Brucellosis Complications in West Asia: A Systematic Review and Meta-Analysis.

BACKGROUND: Brucellosis is a multi-systemic zoonotic infection. The West Asia/Middle East region is an important global hotspot for brucellosis. This systematic review and meta-analysis aimed to aggregate and synthesize all the available evidence regarding the complications of brucellosis in West Asia/Middle East region. METHODS: PubMed, Embase, Scopus, Web of Science, Google Scholar, and Proquest were searched. Selection of studies, data extraction, and the risk of bias assessment were performed in duplicate. Data extraction was performed for 254 complications. Meta-analysis was performed using a random-effects model with Freeman-Tukey double arcsine transformation. Where applicable small-study effects was assessed using funnel plots and Egger's test. Separate by-country, by-age, and by-publication-decade subgroup analyses were performed if feasible. RESULTS: Out of 9518 results, 240 studies (260 references) were included. The majority of the included studies were conducted in Turkey (n = 177). The reported complications varied and different complication categorization systems were detected. The highest pooled estimate was observed for musculoskeletal involvement (50%, 95%CI: 39%-61%, I2 = 96.63%). The evidences is up-to-date until March 4, 2024. CONCLUSIONS: Some complications such as the complications of the eye were not reported in all the countries. Therefore, it's recommended to determine the relative frequency of those complications in regions without such reports. The pooled estimates of different complications of brucellosis were different. There's a need for the standardization of the reporting of the complications of brucellosis to achieve comparability between studies and across different regions.

Rabies control in South and Southeast Asia.

We have the knowledge and tools to eliminate the threat of canine rabies but this disease, nevertheless, remains a public health threat in many parts of the world. Lack of motivation by governments, cultural issues and inadequate funding remain barriers. This is amazing since the number of human rabies deaths worldwide is greater than that from polio, meningococcal meningitis, Japanese encephalitis, yellow fever, SARS, bird flue and other scourges that attract more attention. Safe and effective vaccines are now widely available. Reduced dose effective and less expensive post-exposure vaccination regimens have helped eliminate nerve tissue vaccines in Thailand, Philippines and Sri Lanka. India and Pakistan, the major users of dangerous nerve tissue derived Semple type vaccine, are now considering following suite. Immediate wound care and prompt use of a potent vaccine will save a majority of infected persons. Rabies immunoglobulin, injected into and around bite wounds, provides added safety for the severely exposed. The high cost of rabies immunoglobulin and tissue culture vaccines are remaining barriers, but new manufacturers and the use of intradermal vaccination schedules can reduce costs. Ultimately, it is the need to control rabies in dogs that must occupy most of our attention. The tools are available, but attitudes must change before they can be applied. There have been many new developments since publication of the last WHO rabies expert committee report in 1992 (new version in print)] and we will address those that have practical applicability.

Disseminated Penicillium marneffei infection in southeast Asia.

Disseminated infection with the fungal pathogen Penicillium marneffei is, after extrapulmonary tuberculosis and cryptococcal meningitis, the third most common opportunistic infection in HIV disease in northern Thailand. We report the clinical, microbiological, and therapeutic features of a large series of HIV-infected adults with disseminated P marneffei infection. From August, 1987, to June, 1992, 92 patients with P marneffei infection confirmed by culture were seen at Chiang Mai University Hospital, of whom 86 were also infected with HIV. Clinical information was available for 80 of these patients. The most common presenting symptoms and signs were fever (92%), anaemia (77%), weight loss (76%), and skin lesions (71%). 87% of patients presenting with skin lesions had generalised papules with central umbilication. Presumptive diagnosis was made in 50 patients by microscopic examination of Wright's-stained bone-marrow aspirate and/or touch smears of skin biopsy or lymph-node biopsy specimens. Most patients who were diagnosed responded initially to amphotericin or itraconazole, whereas most who were not diagnosed and treated died. 12 patients relapsed within 6 months of cessation of treatment. P marneffei has become an important pathogen of HIV-associated opportunistic infection in Thailand.
