Thai national guidelines for the prevention of mother-to-child transmission of HIV: March 2010.

Thailand has been one of the leading developing countries to implement a national program to prevent mother-to-child transmission (MTCT) of HIV. Although the recent transmission rate has been low, the goal is to eliminate MTCT altogether. The Thai National HIV Guidelines Working Group issued treatment guidelines to prevent MTCT in Thailand in March 2010. These guidelines will be implemented nationwide within a year. The most important aspects of these new guidelines are as follows: Treatment in HIV-infected pregnant women who have not been on antiretroviral treatment prior to pregnancy. Antepartum treatment is recommended for all pregnant women regardless of CD4 count with highly active antiretroviral therapy (HAART) containing zidovudine (AZT) + lamivudine (3TC) + lopinavir/ritonavir (LPV/r). Treatment should be started immediately irrespective of gestational age in women with CD4 count <350 cells/ mm3, and as early as 14 weeks of gestation in those with CD4 count >350 cells/mm3. After delivery, women with baseline CD4 count <350 cells/mm3 are referred for long-term care and HAART according to the National Adult HIV Treatment and Care Guidelines 2010. Women with CD4 count >350 cells/mm3 do not need HAART and can stop all drugs after delivery. The treatment in infants includes AZT syrup for four weeks and exclusive formula feeding. Treatment in HIV-infected pregnant women who conceive while on HAART. Women who are stable on HAART should continue the treatment during the whole period of pregnancy. Those who are taking efavirenz (EFV) and present during the first trimester should have EFV switched to another drug. Whenever possible, AZT should be used during pregnancy. Treatment in infants is similar to the above scenario. Treatment in women who present in labor without antenatal care. Single-dose nevirapine (SD-NVP) 200 mg must be given immediately along with oral AZT 300 mg every three hours until delivery, or oral AZT 600 mg given as a single dose. The tail therapy of AZT + 3TC + LPV/r for four weeks should be given unless these women have a CD4 count of <350 cells/mm3 and therefore require life-long HAART. SD-NVP should not be given if the women are to deliver within two hours. The infants in this situation should receive AZT + 3TC + NVP for four weeks. Treatment during delivery and mode of delivery. During labor, oral AZT 300 mg every three hours or oral AZT 600 mg given as a single dose is recommended regardless of antepartum antiretroviral (ARV) regimen or the woman’s history of AZT resistance. Elective caesarean section is suggested in women who did not receive HAART (including those without antenatal care), received HAART for less than four weeks prior to delivery, had poor adherence, or had incomplete viral suppression at 36 weeks of gestation.

The National Access to Antiretroviral Program for PHA (NAPHA) in Thailand.

To describe the development, components, initial results and lessons learned from Thailand's National Access to Antiretroviral Program for People living with HIV/AIDS (NAPHA), a historical review was conducted and program monitoring was analyzed. The national antiretroviral therapy program at different levels of the public health system was implemented with all major program components; ARV protocol development, health care professional training, drug supply chain management, laboratory network formation, monitoring and evaluation, and multi-sector and PHA involvement since 2001, which was based on elements of research, pilot projects, training, national guideline development, experiences and policy making. A national monitoring system was developed to monitor the progress of the program. From February 2001 to December 2004, the monitoring reports received from implementing hospitals showed that 58,133 cases had received antiretroviral therapy (ART), and 85% (49,477) of them were continuing to take ARV drugs. In conclusion, the NAPHA was implemented nationwide with comprehensive systems. The reports indicate achievement of expansion of the ART program. Lessons learned from the program initiation and scaling up show local leadership, comprehensive training, adherence, and coordination are essential to program effectiveness and sustainability.

HIV/AIDS care and treatment in three provinces in northern Thailand before the national scale-up of highly-active antiretroviral therapy.

In 2003, Thailand launched a program to place 50,000 persons on highly active antiretroviral therapy (HAART) by the end of 2004, following a series of efforts since the early 1990s to develop comprehensive HIV/AIDS care services. To evaluate existing services and needs in advance of the national HAART scale-up, in 2002 we surveyed 31 hospitals and 389 community health centers in three northern Thai provinces, and interviewed 1,015 HIV-infected patients attending outpatient clinics. All hospitals offered voluntary HIV counseling and testing, 84% provided primary prophylaxis for Pneumocystis carinii pneumonia, 58% for tuberculosis, 39% for cryptococcal meningitis, and 87% had some experience providing antiretroviral therapy. Community health centers provided more limited service coverage. Of patients interviewed, 63% had been diagnosed with symptomatic HIV disease, and of these, 32% reported ever receiving antiretroviral therapy; 51 % of all patients had received a CD4 T-lymphocyte count. Thailand's current national HAART scale-up is being performed in a setting of well-developed hospital-based services introduced over the course of the epidemic.
