Perception and social consequences of tuberculosis: A focus group study of tuberculosis patients in Sialkot, Pakistan

Treatment defaulting is one of the major causes of the failure of TB control programs. In Bethania Hospital. Sialkot, defaulting rates are high: 72% for the standard 12 months course and 56% for the 8 months course. Attrition is especially important in the first weeks of treatment: < 70% of the patients start the 10th week of treatment. A focus group discussion study has been carried out to gain a better understanding of the impact of social stigmatization, treatment cost and pregnancy on defaulting. The study population consisted of 3 male and 3 female groups each with 8 hospitalized TB patients. The study shows that TB is perceived as a very dangerous, infectious and incurable disease. This perception has many social consequences: stigmatization and social isolation of TB patients and their families; diminished marriage prospects for young TB patients, and even for their family members; TB in one of the partners may lead to divorce. Due to fear patients often deny the diagnosis and reject the treatment. While both male and female TB patients face many social and economical problems, female patients are more affected. Divorce and broken engagements seem to occur more often in female patients. Females are usually economically dependent on their husbands and family in law, and need their cooperation to avail of treatment. The belief that pregnancy enhances the risk for relapse decreases their marriage prospects. Pregnancy is also a reason for stopping TB treatment as both are considered as incompatible. The findings of this study reveal the urgent need for a health education campaign to convince the general population that tuberculosis is curable. All health care providers should act as destigmatizers.

The development of the Tuebingen Cushing's disease quality of life inventory (Tuebingen CD-25). Part I: construction and psychometric properties

Objective To develop a disease‐specific questionnaire for Cushing’s disease (CD), the Tuebingen Cushing’s disease quality of life inventory (Tuebingen CD‐25). Methods Sources for item generation consisted of technical literature, interviews with patients and the rating of neurosurgeons, endocrinologists and a neuropsychologist. A preliminary inventory with 64 items was handed out to 63 CD patients. Twenty‐eight patients filled out the questionnaire preoperative, the remaining 35 patients evaluated their health‐related quality of life (HRQoL) retrospectively. Item reduction and scale generation followed the principles of classical test theory. Validation was performed with the WHOQoL‐BREF. Results The final version of the Tuebingen CD‐25 contained 25 items, showed high reliability (Cronbach’s alpha = 0·93) and validity (r = ?0·65) and includes the subdomains Depression, Sexual Activity, Environment, Eating Behaviour, Bodily Restrictions and Cognition. The retrospective rating of the Tuebingen CD‐25 showed similar results compared to the pretreatment group. We found a non‐linear correlation between the Tuebingen CD‐25 scores and patients’ age, younger (21–30 years) and middle‐aged (51–60 years) patients having inferior HRQoL than patients between 31 and 50 years and older than 61 years. Preoperative 24 h urinary free cortisol (UFC) levels correlated significantly with the subscale Cognition and only marginally failed significance level for the subscale Eating Behaviour, while preoperative cortisol and ACTH levels did not correlate with any scale. Conclusion The Tuebingen CD‐25 is a valid and reliable instrument to evaluate HRQoL in CD. Based on impairment of HRQoL for the different subdimensions, specific support can be offered to the patients.     

Case reports

The clinical presentation of lead intoxication may vary widely and in the absence of a high clinical index of suspicion, the diagnosis may be missed. The effects of lead on mitochondrial oxidative phosphorylation and its interaction with calcium-mediated processes explain the heterogenous presentation. In this case report, the diagnosis was finally made when bilateral wrist drop developed on top of abdominal cramps and anemia. Before, ascites raised the suspicion of a tumor. Therefore, each element of the triad of unexplained anemia, abdominal cramps, and bilateral wrist (or foot) drop should lead any physician to consider the diagnosis of lead intoxication. This case also illustrates the importance of a careful and meticulous social history in patient management.     

Secretion, degradation, and elimination of glucagon-like peptide 1 and gastric inhibitory polypeptide in patients with chronic renal insufficiency and healthy control subjects

Glucagon-like peptide 1 (GLP-1) and gastric inhibitory polypeptide (GIP) are important factors in the pathogenesis of type 2 diabetes and have a promising therapeutic potential. Alterations of their secretion, in vivo degradation, and elimination in patients with chronic renal insufficiency (CRI) have not yet been characterized. Ten patients with CRI (aged 47 +/- 15 years, BMI 24.5 +/- 2.2 kg/m(2), and serum creatinine 2.18 +/- 0.86 mg/dl) and 10 matched healthy control subjects (aged 44 +/- 12 years, BMI 24.9 +/- 3.4 kg/m(2), and serum creatinine 0.89 +/- 0.10 mg/dl) were included. On separate occasions, an oral glucose tolerance test (75 g), an intravenous infusion of GLP-1 (0.5 pmol. kg(-1). min(-1) over 30 min), and an intravenous infusion of GIP (1.0 pmol. kg(-1). min(-1) over 30 min) were performed. Venous blood samples were drawn for the determination of glucose (glucose oxidase), insulin, C-peptide, GLP-1 (total and intact), and GIP (total and intact; specific immunoassays). Plasma levels of GIP (3-42) and GLP-1 (9-36 amide) were calculated. Statistics were performed using repeated-measures and one-way ANOVA. After the oral glucose load, plasma concentrations of intact GLP-1 and intact GIP reached similar levels in both groups (P = 0.31 and P = 0.87, respectively). The concentrations of GIP (3-42) and GLP-1 (9-36 amide) were significantly higher in the patients than in the control subjects (P = 0.0021 and P = 0.027, respectively). During and after the exogenous infusion, GLP-1 (9-36 amide) and GIP (3-42) reached higher plasma concentrations in the CRI patients than in the control subjects (P < 0.001 and P = 0.0033, respectively), whereas the plasma levels of intact GLP-1 and GIP were not different between the groups (P = 0.29 and P = 0.27, respectively). Plasma half-lives were 3.4 +/- 0.6 and 2.3 +/- 0.4 min for intact GLP-1 (P = 0.13) and 5.3 +/- 0.8 and 3.3 +/- 0.4 min for the GLP-1 metabolite (P = 0.029) for CRI patients vs. healthy control subjects, respectively. Plasma half-lives of intact GIP were 6.9 +/- 1.4 and 5.0 +/- 1.2 min (P = 0.31) and 38.1 +/- 6.0 and 22.4 +/- 3.0 min for the GIP metabolite (P = 0.032) for CRI patients vs. healthy control subjects, respectively. Insulin concentrations tended to be lower in the patients during all experiments, whereas C-peptide levels tended to be elevated. These data underline the importance of the kidneys for the final elimination of GIP and GLP-1. The initial dipeptidyl peptidase IV-mediated degradation of both hormones is almost unaffected by impairments in renal function. Delayed elimination of GLP-1 and GIP in renal insufficiency may influence the pharmacokinetics and pharmacodynamics of dipeptidyl peptidase IV-resistant incretin derivatives to be used for the treatment of patients with type 2 diabetes.
