Following completion of additional workup, she was started on anakinra 100 mg daily with prompt resolution of her symptoms. Due to the rarity of the disease, the diagnosis of Schnitzler’s syndrome is often delayed, with an average time to diagnosis being approximately 5 years. The symptoms in most cases can be debilitating and add to significant morbidity as noted in our patient, who required bilateral hip arthroplasty at a much younger age than expected. Published reports discuss the poor quality of life associated with the delayed diagnosis and unawareness of potential end organ damage. With our case report we like to highlight the disease characteristics for an early identification to prevent further organ damage believed to be from chronic inflammation. Early diagnosis and treatment with agents such as interleukin-1 (IL-1) inhibitors can promptly provide symptomatic relief, reduce inflammation and prevent organ damage.Leflunomide has not been previously associated with thrombotic thrombocytopenic purpura (TTP), a rare life-threatening clinical syndrome characterized by thrombotic microangiopathy (TMA) due to inability to cleave ADAMTS13. Here, we present the first case of leflunomide-induced TTP. Selleck p-Hydroxy-cinnamic Acid Our patient developed encephalopathy, thrombocytopenia, anemia and hyperbilirubinemia 2 months after starting leflunomide. Schistocytes were noted on peripheral smear and ADAMTS13 activity was low ( less then 5%), consistent with acquired TTP. He received therapeutic plasma exchange, corticosteroids, rituximab and caplacizumab with normalization of hemolysis labs and ADAMTS13 activity. However, pancytopenia persisted, raising the suspicion for leflunomide toxicity. Oral cholestyramine treatment was empirically started before teriflunomide (a leflunomide metabolite) level was found to be elevated. Blood counts normalized after cholestyramine and have remained normal at last follow-up over a year later. This is the first reported case of TTP precipitated by leflunomide. Our case highlights the importance of recognizing drugs as an etiology of TMA and adds leflunomide to this list.Cases of late onset neutropenia (LON) after rituximab therapy have been documented, but few cases have been documented of early onset neutropenia (EON). We present a case report of a patient with mantle cell lymphoma who presented with EON, only 6 days after initiation of rituximab therapy, notable for the shortest duration to EON ever reported in literature. Throughout this paper, we explore the potential pathogenesis and incidence of EON with the help of our unique case.TERC variant telomere biology disorders (TBDs) are a rare, heterogenous group of disorders that arise from germline variants in TERC, a gene that encodes for the RNA component of telomerase. Variants in TERC lead to accelerated telomere attrition and can manifest as many different phenotypes. In this case series, we aimed to add to the literature describing TERC variant TBDs by reporting cases from two unrelated families from Atlantic Canada. The first case, a previously described germline TERC variant, n.107G>T (NR_001566.1), was identified in a young woman with myelodysplastic syndrome (MDS) and found to segregate with cytopenias in the family. This case represents a unique phenotypic presentation this variant has not previously been described in patients with MDS and adds important segregation data to the literature. The second case, a novel TERC n.437T>G variant, was identified in a patient with both aplastic anemia and pulmonary fibrosis manifesting in his early 30s. We report these novel cases of germline TERC variants in order to help clinicians recognize TBDs, as well as to add important supporting information for the pathogenicity of these variants.

Infections are an important cause of morbidity and mortality in T-cell lymphomas. Factors contributing to increased risk of infection include the nature of the underlying disease, as well as treatment-associated immunosuppression. Currently there are few reports describing the types of infections, including preventable infections, in this cohort of patients. The aim of the study was to identify the type, frequency and severity of infection in patients with T-cell lymphoma undergoing treatment.

A case series was performed on all patients with T-cell lymphoma over a 5-year period from 2011 to 2016 at a tertiary Australian hospital. Information was collected from medical record review regarding patient demographics, lymphoma treatment and outcomes, and infectious outcomes. Severe infections were recorded, defined as infection requiring hospitalization.

Sixteen patients were identified with a diagnosis of T-cell lymphoma who received treatment at our institution. There were 42 discrete episodes of severe in. Our data suggests that fungal prophylaxis may be indicated with T-cell lymphoma.

Correction of vitamin D deficiency through administration of either vitamin D

or D

has been shown to reduce chronic bone pains and frequency of acute bone pains, increase bone density as well as improve growth stature in children with sickle cell anemia (SCA). Findings vary on the effectiveness of the two forms of the vitamin. The current study was carried out to compare the effectiveness of a 6-week treatment course of vitamin D

and D

in the correction of hypovitaminosis D (vitamin D insufficiency and deficiency) as well as evaluate treatment response to derangement of serum calcium and alkaline phosphatase (ALP) in children with SCA in steady state.

The study was a randomized, double-blind clinical trial of 174 children with SCA aged 1 – 18 years. Subjects with hypovitaminosis D (baseline serum 25-hydroxyvitamin D (25(OH)D) below 75 nmol/L) were randomized into two treatment arms. Each arm treated either of the two forms of vitamin D had a once weekly dose of 50,000 IU for a period of 6 weeks.

Median rise in serum 25(OH)D after 6 weeks of oral vitamin D

or D

was similar between the two groups (median rise in 25(OH)D of 17.8 nmol/L in D

, 15.3 nmol/L in D

groups). Also, there was no significant difference in the proportion of subjects that improved in their vitamin D status in both treatment arms (P = 0.409). Treatment was significantly associated with increase in proportion of subjects with normal serum calcium (P ≤ 0.001) and decrease in proportion of subjects with elevated serum ALP (P ≤ 0.001).

Once weekly dose (50,000 IU) of either vitamin D supplement has equal effectiveness in correction of hypovitaminosis D. However, vitamin D

may be cost-effective because it is cheaper.

Once weekly dose (50,000 IU) of either vitamin D supplement has equal effectiveness in correction of hypovitaminosis D. However, vitamin D3 may be cost-effective because it is cheaper.
