Abstract Background Although visceral leishmaniasis is endemic in various parts of India, management is still a challenge due to multiple drug resistance. Here we describe a case of a 50 years old female who was diagnosed with visceral leishmaniasis at a tertiary care hospital in northern parts of India and was managed with a repeated trial of liposomal Amphotericin B. Methods Case Discussion: The patient presented in the outpatient department with recurrent fever, mild intermittent abdominal discomfort associated with generalized weakness for the past one month. On per abdomen examination the patient had splenomegaly with spleen palpable 8 cm below the left costal margin. Blood investigations were suggestive of pancytopenia (leukocyte of 1800/cumm, Hemoglobin 7 g/dl, Platelet count: 80,000/cumm) along with severe neutropenia (Absolute neutrophil count: 400/cumm) . The CT abdomen showed massive splenomegaly (23 cm) with mild hepatomegaly . Leishmania Immunoglobulin G was positive. Bone marrow biopsy revealed hyperproliferative marrow with plasmacytosis (12-15%). Bone marrow Leishman-Donovan bodies were negative. Serum immunofixation was negative for M spike and serum light chain assay was also negative. She was managed with liposomal Amphotericin B (3mg/kg) for 7 days and was subsequently discharged. After 3 months, the patient again presented with continuous fever, lethargy, running nose, palpitations. Her blood work-up revealed severe pancytopenia again. She was tested for Leishmania anti- rk39 antibody, which was positive. She was given a repeat trial of Liposomal Amphotericin B with a different regimen-3 mg/kg dose on Day 1 to 5, followed by 6th dose on Day 14, followed by 7th dose on Day 21, as per the FDA approved regimen. Patient recovered well. The most recent total leukocyte counts eventually improved to 4800 with normal differential count. Platelets increased to 180,000, Hemoglobin was around 10.8g/dl and spleen was non palpable on physical examination. Results Treatment of leishmania can become complicated due to resistance to various drugs especially when a single agent is being given. Conclusion But in resource limited countries different regimens of liposomal amphotericin B can be tried which might be helpful due to speedy clinical recovery and cost effectiveness.

In 2012, the Systemic Lupus International Collaborating Clinics (SLICC) group published a new set of classification criteria for systemic lupus erythematosus (SLE). Studies applying these criteria to real-life scenarios have found either equal or greater sensitivity and equal or lower specificity to the 1997 ACR classification criteria (ACR 97). Nonetheless, there are no studies that have used the SLICC 12 criteria to investigate the incidence of lupus. We used the resource of the Rochester Epidemiology Project to identify incident SLE patients in Olmsted County, Minnesota, from 1993 to 2005, who fulfilled the ACR 97 or SLICC 12 criteria. A total of 58 patients met criteria by SLICC 12 and 44 patients met criteria by ACR 97. The adjusted incidence of 4.9 per 100,000 person-years by SLICC 12 was higher than that by ACR 97 (3.7 per 100,000 person-years, p = 0.04). The median duration from the appearance of first criterion to fulfillment of the criteria was shorter for the SLICC 12 than for ACR 97 (3.9 months vs 8.1 months). The higher incidence by SLICC 12 criteria came primarily from the ability to classify patients with renal-limited disease, the expansion of the immunologic criteria and the expansion of neurologic criteria.
