Serial regimen formulation guided by overall treatment effectiveness resulted in treatment outcomes comparable to those obtained with first-line treatment. Confirmatory formal trials in populations with high levels of human immunodeficiency virus coinfection and in populations with a higher initial prevalence of resistance to second-line drugs are required.

The distribution of ABO and Rh-D blood groups was studied among 150,536 blood donors screened at the Dr John Scudder Memorial Blood Bank, Christian Medical College Hospital, Vellore, over a period of 11 years (April 1988 to March 1999). The most common blood group was found to be group O [58,330 (38.75%)], followed by group B [49,202 (32.69%)], and group A [28,372 (18.85%)]. The least common blood group was AB group [7,930 (5.27%)]. A2 or A2B groups were found in 3.01% and 1.43% of donors, respectively. The prevalence of Rh-D negative group was found in 8,225 (5.47%) donors. Bombay group (H negative non-secretor, genotype hh phenotype Oh) was found in six donors (0.004%). Although the incidence of Rh-D negative group was identical to previously published data from North India, the most common blood group was O group in our study as opposed to B group.

Background Immunosuppressive therapy (IST) is the alternative treatment in children with aplastic anemia (AA) who do not have an HLA‐matched sibling. The aim of this study is to evaluate the outcome of children with AA treated with IST. Methods We retrospectively reviewed the hospital records of children with AA from 1984 to 2004, treated at our institution with antithymocyte globulin (ATG), cyclosporine (CS), and short course of prednisone. Result Forty‐two patients were treated with IST (24 boys, 18 girls); of whom 26% received G‐CSF. The median age at diagnosis was 8.5 years. Sixty‐nine, 19, and 12% were diagnosed with severe, very severe, and moderate AA, respectively. Twenty‐one percent had hepatitis‐associated AA. Median follow‐up time was 53.3 months. Sixty‐two percent had complete response; 19% had partial response. Two patients relapsed and received a second course of ATG; both had a partial response. The actuarial 5 years survival rate was 67.5%. Two patients developed myelodysplastic syndrome (MDS); both received long‐term G‐CSF and had partial response after two courses of IST. Fifteen percent of survivors had significant hypertension which persisted after CS was discontinued. Conclusions This study shows promising response in children with AA treated with IST; however, the outcome was inferior to our institutional results with hematopoietic stem cell transplantation from a sibling donor. Hypertension and MDS are late complications. Longer follow‐up, larger cohorts, and prospective studies are warranted to evaluate late complications and risk factors.

The clinical characteristics and outcome of 15 patients with acute myelogenous leukemia (AML) who experienced relapse at least 5 years after induction of complete remission (very late-relapse AML) are described. This subgroup represented 3% of all relapsed patients seen at this institution over the same time period. There were eight males in this cohort and the median age at diagnosis was 48 years (range 13 - 77 years). Nine patients had M4/M5 French - American - British (FAB) classification subtype and most had intermediate risk cytogenetics. The median duration of first complete remission (CR-1) was 9 years (range 5.2 - 11.5 years). Thirteen patients (86%) achieved CR-2 with reinduction therapy. The 5-year relapse-free survival and overall survival rates of this cohort were 59% and 51%, respectively. We conclude that very late-relapse AML is a rare event, and that reinduction in these patients is associated with very high CR rates and a potential cure fraction.

Nipah infection was not widespread among abattoir workers in Malaysia and was linked to exposure to pigs. Since it may be difficult to identify Nipah-infected pigs capable of transmitting virus by clinical symptoms, using personal protective equipment, conducting surveillance for Nipah infection on pig farms which supply abattoirs, and avoiding handling and processing of potentially infected pigs are presently the best strategies to prevent transmission of Nipah virus in abattoirs.

Background: Psoriasis continues to have unmet needs in its management despite introduction of newer molecules. Monotherapy with these newer agents may not achieve therapeutic goals in all cases, hence necessitating their combinations with other molecules. Improved understanding of newer as well as conventional treatment modalities and experiences in their combinations hence necessitates therapeutic guidelines for their use in psoriasis.Objective: To review the combinations of treatments reported in literature and recommendations for their use based on best current evidence in literature.Methods: A literature review of MEDLINE database for studies evaluating combinations of newer therapies with conventional therapies in psoriasis was done. Newer therapies were identified as biologic disease modifying anti rheumatic drugs and other molecules such as apremilast while conventional therapies included methotrexate, cyclosporine, or retinoids, phototherapy and others. The therapeutic guidelines are proposed with the aim to provide evidenced based approach to combine newer and conventional agents in day-to-day psoriasis management.Findings: Combination of acitretin and narrow band ultraviolet B (NB-UVB)/Psoralen with ultraviolet A (PUVA) achieves faster clearance and allows reduction of dose of the latter. A variable outcome is reported of methotrexate with TNF-α inhibitors vs. TNF-α inhibitors alone, although addition of methotrexate appears to reduce immunogenicity of TNF-α inhibitors thereby preventing formation of anti-drug antibodies especially in case of infliximab. While combination of acitretin and PUVA is beneficial, combining TNF-α inhibitors and phototherapy too produces better and faster results but long term risks of Non Melanoma Skin Cancers (NMSCs) may preclude their use together. Combination of cyclosporine and phototherapy is not recommended due to greater chances of NMSCs. Adding phototherapy to Fumaric Acid Esters (FAEs) improves efficacy. Apremilast can be safely combined with available biologic agents in patients with plaque psoriasis or psoriatic arthritis not responding adequately to biologics alone. Hydroxyurea and acitretin may be used together increasing their efficacy and reducing doses of both and hence their adverse effects.Conclusion: Selected clinical scenarios shall benefit from combinations therapies, improving efficacy of both conventional and newer agents and at the same time helping reduce toxicity of higher dosages when used individually.

This study evaluates our institution's target trough cyclosporine (CSA) concentrations as predictors of severe acute graft versus host disease (aGvHD) in children receiving either matched related or unrelated hematopoietic stem cell transplantation (HSCT). The outcomes of 87 consecutive children who underwent allogeneic HSCT and received CSA and methotrexate as prophylaxis against aGvHD between October 1, 1999 and September 30, 2002 were retrospectively evaluated. The proportion of time that each patient maintained a whole blood CSA concentration within or above the initial target range (105-155 ng/mL or 155-210 ng/mL) was calculated for each of the following time periods: in each week after HSCT from day 0 to +28; in the week preceding engraftment; and in the week preceding the onset of aGvHD. Patients were prospectively evaluated twice weekly for the presence and severity of aGvHD by senior attending physicians. The relationship between potential predictors and the development of severe aGvHD was examined using univariate logistic regression. The main variables of interest were the proportion of time that therapeutic or supratherapeutic CSA concentrations were maintained; median CSA concentrations; the number of methotrexate doses received; and the use of folinic acid rescue. Mean follow-up time was 3.0+/-1.9 years among children who survived beyond day +100. Three variables were significantly associated with the development of severe aGvHD on univariate analysis: initial CSA target concentration [odds ratio (OR), 0.24; P=0.03], proportion of time the target CSA concentration was achieved during the second week after transplant (OR, 0.16; P=0.02), and proportion of time the target CSA concentration was achieved during the week before engraftment (OR, 0.22; P=0.0489). Multivariable analysis demonstrated an inverse relationship between the median CSA concentration during the week before engraftment and the development of severe aGvHD (OR, 0.99; P=0.045). These results suggest that achievement of our CSA target concentrations is important to aGvHD outcomes.

BACKGROUND AND PURPOSE:Coinfection of neurocysticercosis (NCC) and Japanese encephalitis (JE) has been advocated as more than a chance occurrence resulting in poor outcome. We undertook this study to determine whether the association of the 2 infections is more than a chance occurrence, to define the imaging characteristics of coinfections, and to explore the synergistic effect of NCC in JE.
