Background: Inadequate myelosuppression during maintenance therapy for acute lymphoblastic leukemia (ALL) is associated with an increased risk of relapse. One mechanism is skewed metabolism of 6-mercaptopurine (6MP), a major component of maintenance therapy, which results in preferential formation of the hepatotoxic metabolite (6-methyl mercaptopurine [6MMP]) with low levels of the antileukemic metabolite, 6-thioguanine nucleotides (6TGN). Allopurinol can modify 6MP metabolism to favor 6TGN production and reduce 6MMP. Methods: Patients in maintenance were considered for allopurinol treatment who had the following features: (a) Grade ≥3 hepatotoxicity; (b) Grade ≥2 nonhepatic gastrointestinal (GI) toxicity; or (c) persistently elevated absolute neutrophil count (ANC) despite >150% protocol dosing of oral chemotherapy. Results: From 2013 to 2017, 13 ALL patients received allopurinol: nine for hepatotoxicity, five for inadequate myelosuppression, and three for nonhepatic GI toxicity (four met multiple criteria). Allopurinol was well tolerated, without significant adverse events. Allopurinol resulted in a significant decrease in the average 6MMP/6TGN ratio (mean reduction 89.1, P = .0001), with a significant increase in 6TGN (mean 550.4, P = .0008) and a significant decrease in 6MMP (mean 13 755, P = .0013). Patients with hepatotoxicity had a significant decrease in transaminase elevation after starting allopurinol (alanine transaminase [ALT] mean decrease 22.1%, P = .02), and all with nonhepatic GI toxicity had improved symptoms. Those with inadequate myelosuppression had a significant increase in the time with ANC in goal (mean increase 26.4%, P = .0004). Conclusions: Allopurinol during ALL maintenance chemotherapy is a safe, feasible, and effective intervention for those who have altered metabolism of 6MP causing toxicity or inadequate myelosuppression.
IntroductionSocial support and ego resiliency play a great role in maintaining the physical and mental health of patients with burn injuries. The present study has been designed to compare ego resiliency levels and the degree of social support in patients with a burn injury and their healthy counterparts.MethodsThis study was conducted in two teaching hospitals in Lahore, Pakistan from May 2015 to July 2015. A total of 80 burn patients presenting in outpatient departments of general surgery, plastic surgery, and burn centers of these hospitals were surveyed conveniently, and for comparison, 80 patients presenting in outpatient departments with minor ailments, for routine checkups or follow-ups were recruited. The questionnaire comprised three sections: demographics, the Urdu versions of the Ego Resiliency Scale (ER-89), and the Multidimensional Scale of Perceived Social Support (MSPSS). All data were analyzed in SPSS v. 20 (IBM Corp., Armonk, NY).ResultsPatients with a burn injury were associated with lower scores on the social support scale as well as its subscales assessing support from the significant other, family and friends than their healthy counterparts. However, no significant differences in scores on the ego resiliency scale were reported between these two groups.ConclusionPatients with a burn injury perceived low social support levels from society, which negatively affects their health outcomes. However, their resilience levels were not significantly different from their healthy counterparts.
ObjectivePrevious research indicates that attitudes to pregnancy and motherhood are influenced by social values, culture and religion. This study explores the relationship between social support and unwanted pregnancy among Pakistani women. This cross-sectional study was conducted at four teaching hospitals in Lahore in 2014.ResultsA total of 500 pregnant women who visited the hospitals’ obstetrics and gynecology departments were asked to respond to a questionnaire consisting of respondents’ characteristics and the Social Provisions Scale (SPS). Logistic regression analyzed the predictors of unplanned pregnancy. Unwanted pregnancies were more likely to occur among pregnant women from rural areas, with low scores on the SPS ‘reassurance of worth’ sub-scale, no history of contraceptive use, and who already had at least one son than those with no sons.Electronic supplementary materialThe online version of this article (10.1186/s13104-018-3696-8) contains supplementary material, which is available to authorized users.
