Successful Renal Transplant in End-Stage Renal Disease with Chronic Immune Thrombocytopenia using Thrombopoietin Receptor Agonists and Intravenous Immunoglobulin.

Chronic kidney disease in immune thrombocytopenia (ITP) is uncommon, and renal transplant in this setting is rare. We discuss the successful renal transplant of a 29-year-old male with chronic ITP. During transplant, he was managed with thrombopoietin receptor agonist eltrombopag, intravenous methylprednisone, and intravenous immunoglobulin to maintain adequate platelet level. He recovered well with no major complications and good graft function and has been stable during the follow-up period. The case report highlights that renal transplantation is a feasible option in patients with ITP, even in the presence of low platelet counts.

Bleeding risk assessment in immune thrombocytopenia.

The bleeding risk in immune thrombocytopenia (ITP) is related not only to low platelet count but also to the presence of platelet dysfunction. However, diagnosing a concomitant platelet dysfunction is challenging as most of the available platelet function assays (PFAs) require a platelet count of greater than 100,000/µL. Sonoclot coagulation and platelet function analyzer works on the principle of viscoelastometry, and results remain unaffected by the platelet counts. To assess the platelet function in adult acute ITP patients with the help of sonoclot coagulation and platelet function analyzer and correlate it with the risk of bleeding. Newly diagnosed acute ITP patients with a platelet count less than 20,000/µL were divided into two groups based on WHO bleeding grade: ITP non-bleeder (ITP-NB) group (WHO bleeding grade ≤1) and ITP bleeder (ITP-B) group (WHO bleeding grade ≥2). Platelet function was assessed by sonoclot in both groups. The patients without significant bleeding (ITP-NB) were followed up monthly for six months with the assessment of platelet function during each contact. Eighty patients (30 ITP-B and 50 ITP-NB) were prospectively included in this study. The median age of patients in the two groups was 37 years and 30 years, respectively. The female-to-male ratio was 4:1 and 1:1 in ITP-B and ITP-NB groups. The median platelet count in ITP-B and ITP-NB was 12000/µL (range 1000-19000/µL) and 8000/µL (range 1000-19000/µL), respectively. Mean platelet functions by sonoclot in both groups were lower than the normal cut-off (>1.6). However, the mean platelet function in the ITP-B group (0.2 + 0.17) was significantly lower than the ITP-NB group (1.2 ± 0.52) (p = 0.01). During the follow-up period of 6 months, patients in ITP-NB with a normal platelet function (>1.6) on sonoclot had lesser episodes (one episode) of clinically significant bleeding than patients with a low platelet function (4 episodes). Patients with acute severe thrombocytopenia and bleeding phenotype have a greater abnormality on platelet function by sonoclot than patients with non-bleeding phenotype. This information may help in taking therapeutic decisions in patients with acute ITP.

The clinical profile, management, and outcome of febrile neutropenia in acute myeloid leukemia from resource constraint settings.

INTRODUCTION: Acute myeloid leukemia (AML) is the commonest leukemia in adults. Mortality in thew first 30-days ranges from 6% to 43%, while infections account for 30-66% of early deaths. We aim to present our experience of infections in newly-diagnosed AML. METHOD: This prospective, observational study, was undertaken at a tertiary care hospital in Northern India. Patients with confirmed AML (bone marrow morphology and flow cytometry) and who had developed febrile neutropenia (FN), were included. RESULT: A total of fifty-five patients were included in the study. The median age of the patients was 47.1 years (12-71) and 28 (50.9%) were males. Fever (33, 60%) was the commonest presentation at the time of diagnosis. One or more comorbid conditions were present in 20 patients (36.36%). Infection at presentation was detected in 17 patients (30.9%). The mean duration to develop febrile neutropenia since the start of therapy was 11.24 days. With each ten-thousand increase in white blood cell (WBC) count, the mean number of days of FN development decreased by 0.35 days (p = 0.029). Clinical and/or radiological localization was possible in 23 patients (41.81%). Thirty-four blood samples (34/242, 14.04%) from 26 patients (26/55, 47.3%) isolated one or more organisms. Gram negative bacilli (GNB) were isolated in 24 (70.58%) samples. Burkholderia cepacia (8/34, 23.52%) was the commonest organism. The number of days required to develop febrile neutropenia was inversely associated with overall survival (OS). However, when compared, there was no statistically significant difference in OS between patients developing fever on day-10 and day-25 (p = 0.063). Thirteen patients (23.63%) died during the study period. DISCUSSION: Low percentage of blood culture positivity and high incidence of MDR organisms are a matter of concern. Days to develop febrile neutropenia were inversely associated with overall survival (OS), emphasizing the importance of preventive measures against infections. CONCLUSION: Infections continues to be a major cause of morbidity and mortality among AML patients.

Safety and efficacy of azathioprine in immune thrombocytopenia.

BACKGROUND: Immune thrombocytopenia (ITP) is a benign hematological disorder characterized by low platelet counts in peripheral blood and spectrum of various bleeding manifestations. Azathioprine is one of the effective, readily available, and affordable immunosupressants available for ITP management in developing countries. We aimed to study the efficacy and long-term safety profile of our patients with ITP who were treated with azathioprine. METHOD: This was a retrospective, single-center study conducted at a tertiary care hospital in Northern India. The patients who had received at least one line of therapy before receiving azathioprine were included in this study. All patients received oral azathioprine at a dose of 1 mg/kg/day (50 mg or 100 mg tablet formulations were used), which was increased up to 2 mg/kg/day depending upon the response and adverse effects. RESULT: Sixty-three patients were analyzed. Their median age was 28 years (range 15-68); 29/63 patients (46.03%) were females. The median duration from diagnosis to azathioprine initiation was 539 days (323 days-980.5 days). The patients included in the study had received a median of 3 (range 1-6) prior lines of therapies; 38/63 patients (60.32%) had received ≥3 prior therapies. Six patients (9.5%) had relapsed after splenectomy, and 16 patients (25.4%) had relapsed after receiving rituximab. The mean baseline platelet count was 10000/µL. The median time to response was 95 days (90 days-not reached) and the cumulative overall response rate (complete and partial response) at day 90 was 38.1%. Only one patient achieved complete response with azathioprine in our study. The cumulative rate of relapse at five years was 21.2%. Twenty-six patients stopped azathioprine after achieving some response (CR/PR) with Azathioprine for a median duration of 1067.5 days (range: 236 days-2465 days). They were followed up for a median of 870 days (range: 392 days-1928 days), and twelve of them relapsed. Twenty-six patients (26/63, 41.27%) reported one or more adverse events while on azathioprine. Leucopenia was the most frequent adverse event, followed by anemia and hepatobiliary laboratory abnormalities. Serious adverse events (grade ≥3 CTCAEv4) were noted in three patients (4.7%). One patient succumbed to severe sepsis multiorgan dysfunction while being on treatment. CONCLUSION: We conclude that azathioprine has a good response rate in chronic ITP patients. It is well-tolerated with minimal and manageable side effects.

Randomized controlled trial of twice-daily versus alternate-day oral iron therapy in the treatment of iron-deficiency anemia.

Recent studies in iron-depleted women have challenged the current approach of treating iron-deficiency anemia (IDA) with oral iron in divided daily doses. Alternate day dosing leads to more fractional absorption of iron. In this randomized controlled trial, we looked at the efficacy and safety of alternate-day (AD) versus twice-daily (BD) oral iron in all severity of IDA. Total of 62 patients were randomized, 31 patients in BD arm received 60 mg elemental iron twice daily while 31 patients in AD arm received 120 mg iron on alternate days. The primary endpoint of 2 g/dl rise in hemoglobin was met in significantly more patients in the BD arm at 3 weeks (32.3% vs. 6.5%, p < 0.0001) and 6 weeks (58% vs. 35.5%, p = 0.001). There was a significant rise in the median hemoglobin at 3 (1.6 vs. 1.1, p = 0.02) and 6 weeks (2.9 vs. 2.0 g/dl, p = 0.03) in the BD arm. However, the median hemoglobin rise in the AD arm at 6 weeks was not significantly different than the BD arm at 3 weeks. Alternate-day dosing for 6 weeks and twice-daily dosing for 3 weeks resulted in the provision of the same total amount of iron. There were more reports of nausea in the BD arm (p = 0.03). In conclusion, the choice of twice-daily or alternate-day oral iron therapy should depend on the severity of anemia, the rapidity of response desired, and patient preference to either regimen due to adverse events.
