Visceral leishmaniasis (VL), a life-threatening parasitic infection, is endemic in the Mediterranean region. Diagnosis of VL is based on epidemiologic, clinical, and laboratory findings. However, sometimes, clinical features and laboratory findings overlap with those of autoimmune diseases. In some cases, autoantibodies are detected in patients with VL and this could be a potential diagnostic pitfall. In this study, we have reported on a three-year-old girl from a VL-endemic area in Iran, who presented with prolonged fever and splenomegaly. Bone marrow examination, serologic tests, and the molecular PCR assay were performed; however, results were inconclusive. The levels of anti-double stranded DNA, cytoplasmic antineutrophil cytoplasmic autoantibody, and perinuclear antineutrophil cytoplasmic autoantibody were elevated and, at the end, splenic biopsy was performed. The splenic tissue PCR test detected the DNA ofLeishmania infantum. The patient’s condition improved with anti-Leishmaniatherapy, and the autoantibodies disappeared within the following four months. Clinical presentations and laboratory findings of VL and autoimmune diseases may overlap in some patients.

Careful History

Pancytopenia is an important clinico-haematological entity and striking feature of many serious and life-threatening illnesses. Many haematological and non-haematological diseases involve the bone marrow primarily or secondarily and cause pancytopenia. Decrease in haemopoietic cell production, ineffective haemopoiesis and peripheral sequestration or destruction of the cells are the main pathophysiology of pancytopenia. The cause of pancytopenia thus may be lying in the bone marrow or in the periphery or both. Careful history, physical examination, simple blood work, review of the peripheral blood smear, sometimes bone marrow examination and trephine biopsy are required for diagnosis. Treatment and prognosis depend on the severity of pancytopenia and underlying pathology.

There is paucity of information about the prevalence of hematological disorders in Yemen and neighboring countries .This is the rst project to evaluate the relative spectrum of hematological diseases in Taiz and Ibb governorate Yemen ,by method of bone marrow examination which is considered an important valuable diagnostic tool, for evaluation and nal diagnosis of various hematological and non-hematological disorders especially when CBC and peripheral blood lm study and other investigation failed to give a diagnosis . OBJECTIVES: The aim of this study was to evaluate the spectrum of haematological diseases diagnosed by bone marrow examination in Taiz and IBB governorates Yemen between September 2016 and October 2020 .Patients and method : A total of 1108 patients aged between (1 -100 )years old were evaluated by bone marrow examination at referral hematological center in IBB city Yemen . Relevant investigations were performed when needed. After exclusion of 98 patients with normal bone marrow ndings ,a total of 1010 patients had hematological disorders , and their data were analyzed. There were 527 (52.2 %) males and 483(47.8 %) females . A total of 655(64.9%) patients had benign hematological diseases and 355 (35.1% ) patients had malignant hematological diseases . RESULTS :A total of 138 patients had Iron deciency anemia ,107 had immune thrombocytopenic purpura (ITP) , 92 had hypersplenism,84 had Acute lymphoblastic leukemia ,79 had Acute myeloid leukaemia, 71 had megaloblastic anemia 58 had myeloproliferative disorder , 53 had Chronic myeloid leukemia , 45 had hemolytic anemia ,45had visceral leishmaniasis. 44 had malaria, 38 had chronic lymphocytic leukemia 38 had anemia of chronic disease ,25 had aplastic anemia ,25 had myelodysplastic syndromes, ,21 had anemia of infection ,19 had congenital syndroms,7had multiple myeloma ,6 had mixed deciency anemia and 5 had metastatic deposits , 4 had myeloid leukomoid reaction ,4 had lymphoma inltration and 2 had hairy cell leukemia . Sex- and age-related distribution of the various disorders was also presented. CONCLUSION: The anemias of all types were the most frequently encountered diagnosis followed by acute and chronic leukemias , ITP , Hypersplenism , ,myeloproliferative disorder , visceral leishmaniasis , malaria, myelodysplastic syndrome and congenital syndromes respectively. The other haematological disorders were less common. These ndings are comparable with published data in previous studies done in Yemen and other developing countries

Blood Examination

The laboratory haematologist has a role in the diagnosis of parasitic infections. Peripheral blood examination is critical in the diagnosis of malaria, babesiosis, filariasis and trypanosomiasis. Bone marrow examination is important in the diagnosis of leishmaniasis and occasionally leads to the diagnosis of other parasitic infections. The detection of eosinophilia or iron deficiency anaemia can alert the laboratory haematologist or physician to the possibility of parasitic infection. In addition to morphological skills, an adequate clinical history is important for speedy and accurate diagnosis, particularly in non-endemic areas.

In Brazil, American visceral leishmaniasis (AVL) is caused byLeishmania (Leishmania) chagasi and its main vector isLutzomyia longipalpis. Cases of canine visceral leishmaniasis (CVL) in non-endemic areas have been reported over the last few years throughout the country. The objective of this research note is to describe an autochthonous case of CVL that occurred in the municipality of Volta Redonda, state of Rio de Janeiro, an area where the disease is not endemic, alerting veterinarians and the scientific community to the expansion of this important zoonosis and advising veterinary practitioners on how to deal with a suspicion of CVL. Canine visceral leishmaniasis can be misdiagnosed within a broad spectrum of canine diseases based on clinical and laboratory findings. Therefore, knowledge of its clinical manifestations, specific and sensitive laboratory diagnostic tests and parasitological procedures are of the utmost importance for rapid confirmation and notification of a case, thus contributing directly to the control of a focus.

BACKGROUND: Visceral Leishmaniasis is a chronic disease and was first described in 1903, byLIESHMAN and DONOVAN. The disease is common in tropical and sub tropical areas of the worldwith various hematological manifestations. It is characterized by fever, visceromegaly, weight loss,pancytopenia and hypergammaglobulenemia. The disease is silent killer, invariably killing almost alluntreated patients, but curable with hematological improvement within 4-6 weeks of treatment.OBJECTIVE: To determine the frequency of Visceral Leishmaniasis in patints with cytopenias .MATERIAL AND METHODS: A descriptive study conducted in Pathology department, HayatabadMedical Complex, Hayatabad from September 1, 2012 to August 31, 2013. This study comprises of 126patients, subjected to complete blood counts. Diagnosis were confirmed by finding Amastigote( L/Dbody) from bonemarrow aspirate. All the patients who were referred to pathology Department of thehospital for bone marrow examination, with the results of peripheral blood using automatedHaematology analyzer, Sysmex KX 21 showing cytopenia were included in the study. Consent wastaken from the patient for bone-marrow aspiration procedure. After consent detailed history, physicalexamination was done.Laboratory investigations i.e. full blood count, which includes hemoglobin estimation, white blood cell,red blood, and platelet count.Bone marrow cytology (Giemsa stain) was recorded on the designed profroma.Posterior superior iliac spine (PSIS) was used as the site for aspiration in adults and children over 2years of ageRESULT: Descriptive case series study of 126 patients of peripheral cytopenia. In which 77 (61.1%)patients were males and 49 (38.9%) were female with male to female ratio of 1.57: 1 It was also foundin this study that visceral leishmaniasis was present in 29 (23%) of cases and the male: female were 1.6:1. Result of the automated hematology analyzer of peripheral cytopenic patients in visceralleishmaniasis show that all of the patients were having total leukocyte count less than 4000/cmm(100%). The hemoglobin level wass less than lOgm/dl in 26 cases (87.7%) and more than lOgm/dl inthree cases (10.3%). In case of platelets count, 27 cases (93.1%) were having platelets count less than150000/cmm.CONCLUSION: Incidence of visceral leishmaniasis is highier in children age group 1-10 years, alsomales are more prone than females. Leukopenia is recorded in all (100%) of the cases, followed bythrombocytopenia (93.1%) and anemia (Hb <10gm %) 87.7% cases.KEY WORD: Visceral Leishmaniasis, Kala Azar, Amastigote (L/D body)

Background. Dysphagia can be a serious problem in patients with inflammatory myopathies. It may be associated with nutritional deficit, aspiration pneumonia, and poor prognosis. Case report. We presented a 60-year-old male, suffering from difficulty in swallowing, pain and weaknes in the proximal parts of his extremities, and skin manifestation. Laboratory findings showed increased creatine kinase and aldolase. Antinuclear antibodies to HEP-2 subtrate revealed titer of 1:40. Electromyoneurography demonstrated evidence of a proximal myopathy. A muscle biopsy revealed myositis. The baruim swallow test was remarkable for regurgitation, and nasal emerging of barium. Nuclear magnetic resonance images of cranium was normal. Tumor markers CEA, and Ca 19-9 were increased. A dose of 1 mg daily prednisolone was administered and percutaneous enteral feeding was performed. Two months later, the patient developed febrile state, aspiration pneumonia, and died due to respiratory failure. Conclusion. In cases of dermatomyositis with the serious dysphagia, percutaneous endoscopic gastrostomy should be performed as soon as possible. Owerall survival rate is low, even with an adequate therapy administration. Inflammatory myopathies should be considered in any patient with oropharyngeal dysphagia.

Visceral Leishmaniasis and HIV-AIDS coinfection (VL/HIV) is considered a life-threatening pathology when undiagnosed and untreated, due to the immunosuppression caused by both diseases. Serological tests largely used for the VL diagnosis include the direct agglutination test (DAT), ELISA and immunochromatographic (ICT) assays. For VL diagnosis in HIV infections, different studies have shown that the use of the DAT assay facilitates the VL diagnosis in co-infected patients, since the performance of the most widely used ELISA and ICT tests, based on the recombinant protein rK39, are much less efficient in HIV co-infections. In this scenario, alternative recombinant antigens may help the development of new serological diagnostic methods which may improve the VL diagnosis for the co-infection cases. This work aimed to evaluate the use of the recombinant Lci2 antigen, related to, but antigenically more diverse than rK39, for VL diagnosis in co-infected sera through ELISA assays. A direct comparison between recombinant Lci2 and rK39 was thus carried out. The two proteins were first tested using indirect ELISA with sera from VL afflicted individuals and healthy controls, with similar performances. They were then tested with two different sets of VL/HIV co-infected cases and a significant drop in performance, for one of these groups, was observed for rK39 (32% sensitivity), but not for Lci2 (98% sensitivity). In fact, an almost perfect agreement (Kappa: 0.93) between the Lci2 ELISA and DAT was observed for the coinfected VL/HIV patients. Lci2 then has the potential to be used as a new tool for the VL diagnosis of VL/HIV co-infections.

AbstractVentricular shunting is the usual method for treatment of congenital or acquired hydrocephalus. Immune-mediated glomerulonephritis (shunt nephritis) is a rare but life-threatening complication of this neurosurgical technique. Intraglomerular deposition of circulating immune complexes and the subsequent activation of the classical pathway of serum complement’s cascade result in glomerular inflammation. Membranoproliferative gomerulonephritis is the most common histologic pattern observed in renal biopsy. The diagnosis needs high suspicion and is based on clinical and laboratory findings. Deterioration of renal function in association with signs of infection and low levels of serum complement’s proteins C3 and C4 make the diagnosis possible. The prognosis is variable and depends on the time of diagnosis after the onset of glomerular injury. The optimal treatment includes timely removal of the infected shunt in combination with aggressive antibiotic therapy. In this paper we present the case of a membranoproliferative glomerulonephritis type 1 in a patient with a ventriculoperitoneal shunt. Although this type of shunting is considered safer than the ventriculoatrial one, the risk of complications such as an immune-mediated glomerulonephritis still exists.
