As partner notification (PN) has shown effective in increasing the number of partners of HIV infected patients being tested we aimed to evaluate the feasibility of implementing PN in the West-African country Guinea-Bissau. Patients enrolled were offered the choice of three different PN methods. Acceptance, successful referrals and HIV status of partners were evaluated. Of 697 patients offered PN, 495 (71.0%) accepted and listed 547 partners. At end of follow-up 118 (21.5%) partners had been tested of which 44 (37.3%) were HIV infected. HIV infected partners had a higher median CD4 count at diagnosis compared with index patients; 401 cells/mm 3 versus 240 cells/mm 3 , p < 0.001. The results indicate that implementation of PN is feasible, effective in identifying HIV infected partners and enables initiation of earlier treatment, yet there are major barriers to bringing partners in for testing which should be addressed in order to exploit the full potential of PN.

Background: Diagnosis of Pneumocystis jirovecii (PJ) pneumonia ordinarily requires invasive procedures that could be avoided by PCR methodologies, if these could be designed with adequate cut-off values for confounding background carriage., Methods: We designed a novel quantitative real-time PCR assay to detect the mitochondrial large subunit rRNA gene of PJ in oral washes. To benchmark levels of PJ carriage versus infection, we tested asymptomatic immunosuppressed patients including Danish (n = 88) and West African HIV-infected (n = 142) patients, renal transplant recipients (n = 51), rheumatologic patients (n = 102), patients with inflammatory bowel diseases (n = 98), and healthy blood donors (controls, n = 50). The fungal burden in patients with PJ pneumonia (PCP, n = 7) was also investigated., Results: Danish HIV-infected patients (with viremia/low CD4) and recent transplant recipients were at most risk of being carriers (prevalence of 23% and 16.7% respectively), whereas PJ was rarely detected among rheumatologic patients, patients with inflammatory bowel diseases, and untreated West African HIV patients. PJ was not detected among healthy controls. The fungal burden in patients with PCP fell rapidly on treatment., Conclusions: The quantitative PCR method described could conceivably discriminate between carriage and disease, given suitable threshold values for the former, and predict treatment efficacy by measures of the fungal burden in daily oral washes.
