CENAT- National Center for Tuberculosis and Leprosy Control or the National Tuberculosis Program

Goals and Activities

The goals of this implementing mechanism are to strengthen the capacity of the Cambodian National Tuberculosis Program (NTP) reliably and rapidly to diagnose tuberculosis in people with HIV and prevent the spread of multi-drug resistant Mycobacterium tuberculosis.

WHO endorses the use of liquid culture for M. tuberculosis in resource limited, high TB burden settings. The advantages of using liquid culture, including reduced time to detection as well as an increase in the yield of M. tuberculosis when compared to solid media have been well documented. Rapid differentiation of M. tuberculosis from nontuberculous mycobacterium (NTM) using cost effective identification methods is also critical. This mechanism will implement the MGIT liquid culture system and an immunochromatographic assay for identification of M. tuberculosis in the Battambang Referral Hospital. Battambang province, with a population of nearly 1,000,000, is one of the CDC/GAP's focus provinces. These methods will also be introduced at the national reference laboratory (NRL). Drug sensitivity testing (DST) using the MGIT system will be implemented at the NRL, the only government laboratory providing DST for M. tuberculosis, when the NRL meets international biosafety standards. This mechanism will fund the hiring of a TB laboratory specialist to work with the Cambodian staff to build capacity and sustain the ability of the NRL to perform TB diagnostics.

This mechanism will strengthen the capacity of the NTP to detect more rapidly TB in PLWHA and other patients. Staff will be trained in this advanced technique at both the provincial and the national levels. More rapid detection of infectious cases of TB will help reduce the TB burden in Cambodia. Prompt detection of M. tuberculosis in HIV and TB co-infected individuals can lead to more rapid initiation of treatment.

This mechanism supports TB/HIV activities and measures to prevent the spread of MDR TB in the laboratory and hospitals in the four CDC/GAP focus provinces. Renovation of the NRL will take place to ensure that the laboratory meets international standards for laboratory safety.

Procurement of laboratory supplies has been a challenge for the NTP under the existing national structure. However, the NTP is the principal recipient for Global Fund Round 7 funds and will gain direct experience in procurement of laboratory supplies and equipment. CDC/GAP will work closely with the NTP to ensure that the appropriate materials are purchased and supplied to the laboratories. The CDC/GAP has been instrumental in implementing and animating a technical working group for TB laboratories. This TWG meets monthly and includes public and private organizations with a stake in the laboratory diagnosis of tuberculosis. The NTP, through the TWG, has developed an Action Plan for TB laboratories for 2010-2014 based on the Strategic Plan for the TB Laboratory Network.

Where liquid culture is introduced, contamination of the media is initially a major challenge. Technical assistance will be provided to ensure that appropriate sputum decontamination techniques are used to reduce the contamination rate. Culture yield and contamination rates will be monitored on a monthly basis.

Target Populations and Geographic Coverage

The NTP provides services for the entire population of Cambodia. The laboratory in Battambang provides services to the provinces of Banteay Meanchey, Battambang, Pailin and Pursat. The target population is all persons with tuberculosis, with an emphasis on those TB patients coinfected with HIV.

Making the Most of HIV Resources

The NTP is seeking a long-term supply of reagents for liquid culture through the Global Fund. In addition, MSF has funded liquid TB culture at the regional TB lab in Kompong Cham.

Enhancing Sustainability

By building liquid culture capacity at the national reference laboratory, the NTP will be better able to supervise regional and provincial TB labs. As noted above, it is expected that reagents for liquid culture will come through the Global Fund in the future, making this a self-sustaining program.

M&E

Progress will be monitored by tracking the rate of contaminated cultures, which for a well functioning liquid culture lab should be approximately 10 percent.
