RESUMEN
To avoid unnecessary neoadjuvant chemotherapy in case anticipating a poor therapy response, it is essential to find the pathological parameters that would predict pathological complete response or at least a decrease in tumor burden following neoadjuvant chemotherapy. The purpose of this study is to investigate the hypothesis that tumor infiltrating lymphocytes can predict the efficacy of neoadjuvant chemotherapy and to find the Ki67 cutoff value that best predicts the benefit of chemotherapy. 153 cases of breast cancer were chosen, based on their molecular subtype: triple negative subtype (77) and luminal, HER2-ve subtype (76). Histopathological assessment of pretherapy core biopsies was conducted to assess variable pathological parameters including TILs rates with the aid of immunohistochemical staining for CD20 and CD3. Moreover, core biopsies were stained for Ki67, and the findings were compared to the residual cancer burden following neoadjuvant chemotherapy. On analyzing and contrasting the two groups, a significant association between molecular subtype and pathological complete response was confirmed, while tumor-infiltrating lymphocytes in either group had no effect on therapy response. We used receiver operating characteristic curve analysis to determine that a cutoff of 36% for Ki67 is the most accurate value to predict complete therapy response.
RESUMEN
OBJECTIVE: To assess the safety and efficacy of glucocorticoids (GCs), immunosuppressive agents (IM) and rituximab (RTX), alone or in combination, for the treatment of IgG4-RD. METHODS: Relevant articles published were searched in the databases with relevant key words. Network meta-analysis was conducted, with various outcomes including relapse rate, remission rate and adverse events. Data were calculated with odds ratio (ORs) and 95% CI. P-score was used to rank the treatments. RESULTS: A total of 15 studies involving 1169 patients were included. Network meta-analysis indicated that RTX maintenance therapy had the lowest relapse rate of all treatments (OR = 0.10, 95% CI [0.01, 1.63]), whereas GCs + IM was associated with a lower relapse rate compared with GCs alone (OR = 0.39, 95% CI [0.20, 0.80]). Further, patients treated with GCs + IM had a higher remission rate than those given GCs (OR= 3.36, 95% CI [1.44, 7.83]), IM (OR= 55.31, 95% CI [13.73, 222.73]) monotherapies or RTX induction therapy only (OR= 7.38, 95% CI [1.56, 34.94]). The rate of adverse events was comparable among the different treatment groups. CONCLUSION: Treatment of IgG4-RD patients with GCs and IM was associated with higher remission rates and lower relapse rates, as well as comparable safety profiles compared with GC, IM and RTX induction therapy. RTX maintenance therapy had a larger reduction in the relapse rate compared with GC and IM. The current evidence should be carefully scrutinized as the included studies were observational in design. Larger randomized controlled trials are needed to confirm.

BACKGROUND: Kuwait has a high prevalence and incidence of type 1 diabetes (T1D). At present there is a need for structured educational programs (SEP) specifically tailored for Arabian youth with T1D. This SEP was locally and culturally adapted from the Kids In Control of Food (KICk-OFF) course delivered at the Dasman Diabetes Institute, Kuwait. AIMS: To explore the psychological and social impact of a pilot SEP for Arabian youth with T1D and their mothers through exploring their respective perspectives. METHODS: All 20 participants were interviewed using semistructured interviews individually, with a duration of approximately 30-45 min. The interviews were recorded and then transcribed verbatim. Data were analyzed using an inductive thematic approach. RESULTS: The adolescents gained more self-confidence in managing their diabetes and their mothers were more confident in allowing their children take the lead in their diabetes self-management. Participants were empowered with adequate knowledge about the underlying pathophysiology of glucose metabolism and the nutritional and pharmacological management which made them feel in control and helped them to better cope with diabetes. It reduced diabetes-related family stress and gave them more social freedom, supporting behavioral change for a better lifestyle. CONCLUSIONS: Attending the adapted SEP had a positive impact on adolescents with T1D and their mothers through enhancement of their knowledge and confidence, thus giving them a sense of disease control. This pilot study has proven effective in terms of enhancement of confidence in diabetes management and psychosocial factors. Therefore, there is a need for a wider implementation.

OBJECTIVES: We aimed to determine the quality of life (QoL) of Kuwaiti adults with type 1 diabetes mellitus (T1DM) who used continuous subcutaneous insulin infusions (CSIIs) and to understand their perception of this treatment. BACKGROUND: CSII is an effective and safe alternative to multiple daily injections for T1DM, with the potential to improve both glycemic control and QoL. Although CSII has been widely used in Kuwait, its effectiveness and benefits have not been properly evaluated. Healthcare providers and patients need more information on CSII before its initiation. METHODS: In this qualitative case study, semi-structured individual interviews were performed using a topic guide. Interviews were stopped at data saturation point. Subsequently, a thematic analysis of transcripts was performed. RESULTS: Eighteen adults with T1DM (8 males and 10 females; age 31.4 ± 6.4 years; diabetes duration 17.7 ± 9.5 years; CSII duration 3.6 ± 2.4 years) were recruited from the CSII clinic. Six main themes were studied: health benefits, lifestyle flexibility, improvement of mood and emotion, practical problems, physical and personal effects, and self-confidence to manage diabetes. CSII positively affected the QoL of participants', most notably by enhancing lifestyle flexibility; however, important negative qualities were also reported. CONCLUSION: The identified themes highlight the complexity of the experiences of participants, and can be used to provide a framework to help healthcare providers understand how people with T1DM become aware of their treatment regimens. It is important to identify the positive aspects of CSII and not focus only on its negative effects.

OBJECTIVES: To audit the current clinical practice of continuous subcutaneous insulin infusion (CSII) for the treatment of type 1 diabetes mellitus (T1D) in children and adolescents attending a single centre in Kuwait. METHODS: A one year retrospective audit was performed in children and adolescents with T1D on CSII, who attended the paediatric diabetes clinic, Dasman Diabetes Institute during 2012. The primary outcome measure was glycaemic control as evidenced by glycated haemoglobin (HbA1c) level and the secondary outcome measures were the frequency of monitoring of the risk for microvascular complications and occurrence of acute complications and adverse events. RESULTS: 58 children and adolescents (mean age ± SD: 12.6 ± 4.1 years) were included. Mean HbA1c at baseline was 8.8% (72.7 mmol/mol) and 8.9% (73.8 mmol/mol) at the end of a 12 months observation period. Children with poor control (HbA1c >9.5% (80 mmol/mol) had a significant 1.4% reduction in HbA1c compared with the overall reduction of 0.1% (p=0.7). Rate of screening for cardiovascular risk factors and for long term complications were well documented. However, there was underreporting of acute complications such as severe hypoglycaemia and diabetic ketoacidosis. Only 1.7% of patients discontinued the pump. CONCLUSION: There was no significant change in HbA1c values at the end of 12 months follow up. However, HbA1c values in poorly controlled children improved. CSII requires care by skilled health professionals as well as education and selection of motivated parents and children.
RESUMEN
AIMS: This study had 2 aims: to report data on the incidence of childhood-onset type 1 diabetes in Kuwaiti children aged 0-14 years during 2011 to 2013 and to compare the recent data with those collected during 1992 to 1997. METHODS: All newly diagnosed patients were registered through the Childhood-Onset Diabetes eRegistry (CODeR) in 2011-2013, based on the DiaMond protocol used in 1992-1997. RESULTS: A total of 515 Kuwaiti children (247 boys and 268 girls) aged 0-14 years newly diagnosed with type 1 diabetes were registered from 1 January 2011 to 31 December 2013. Data ascertainment were 96.7%. The mean age ± SD at diagnosis was 8.7 ± 3.4 years in boys and 7.9 ± 3.1 years in girls. The crude incidence rate (95% CI) was 40.9 (37.4-44.6) and the age standardized rate 41.7 (95% 38.1-45.4) per 100,000 per year, 39.3 (34.6-44.4) among boys and 44.1 (39.0-49.7) among girls. A statistically significant increasing trend in incidence was observed as the overall crude incidence rose from 17.7 in 1992-1994 to 40.9 per 100,000 per year in 2011-2013. The Poisson regression model depicting the trend in incidence revealed that, the incidence rates adjusted for age and sex in 2011 to 2013 was 2.3 (95% CI 1.9-2.7) times higher than 1992-1997. CONCLUSIONS: The incidence of type 1 diabetes in Kuwaiti children 0-14 years has doubled in the last 2 decades. The reasons for this increase requires further investigation.

We examined the frequency and severity of diabetic ketoacidosis (DKA) in 679 children and adolescents (0-14 years) at diagnosis of Type 1 Diabetes Mellitus (T1DM) in Kuwait. Between 1(st) January 2011 and 31(st) December 2013, all newly diagnosed children with diabetes were registered prospectively in a population-based electronic register. DKA was diagnosed using standard criteria based on the levels of venous pH and serum bicarbonate. At the time of diagnosis, mild/moderate DKA was present in 24.8% of the children, while severe DKA was present in 8.8%. Incidence of ketoacidosis was significantly higher in young children less than 2 (60.7% vs 32.4% p = <0.005) compared to children 2-14 years old, and a higher proportion presented with severe DKA (21.4% vs 8.3% p = <0.05). No association was seen with gender. Significant differences were found in the incidence of DKA between Kuwaiti and non-Kuwaiti children (31.1% vs 39.8%; p < 0.05). Family history of diabetes had a protective effect on the occurrence of DKA (OR = 0.44; 95% CI = 0.27-0.71). Incidence of DKA in children at presentation of T1DM remains high at 33.6%. Prevention campaigns are needed to increase public awareness among health care providers, parents and school teachers in Kuwait.

BACKGROUND AND STUDY AIMS: As HCV lymphotropism was ascertained, this study was carried out to verify the possible involvement of the spleen in HCV-related chronic hepatitis. PATIENTS AND METHODS: A cross-sectional study was conducted on 97 HCV infected patients attending for treatment with interferon, categorised as follows; before treatment (group I, n=49), non-responders (group II, n=18), responders (group III, n=18) and group IV (n=12) including patients with HCV RNA below detection limit after 24 weeks of treatment. A control group of healthy blood donors (n=19) was enrolled in our study. Conventional ultrasonography was carried out on all participants. Splenic volume was measured and compared between the groups, and its relationship to HCV RNA concentration was investigated. RESULTS: It was found that the splenic volume of patients of both groups I and II is significantly greater than that of the control group (p-values : 0.004 and 0.009, respectively) and, of patients of both groups III and IV. The latter are not significantly greater than that of the control group (p-value: 0.8 and 0.6, respectively). A significant positive relationship was detected between the splenic volume and the HCV RNA concentration in group I (r=0.56, p-value=0.00) but this is insignificant in group II. There is no significant relationship between the splenic longitudinal diameter and the HCV RNA concentration in any of the studied groups. CONCLUSION: The splenic volume positively correlated with HCV RNA concentration in HCV positive patients, but this become insignificant in non-responders to interferon therapy. The successful response to interferon therapy matches with near normal splenic volume whilst non-responders to Interferon therapy matches with increased splenic volume. The change in the viral load leads to a corresponding change in the splenic volume and does not affect the splenic longitudinal diameter.
